SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS We urge you to carefully consider the following important factors that could affect the semiconductor industry and cause actual results of our operations to differ materially from our expectations: o market demand for semiconductors, particularly for digital signal processors and analog chips in key markets, such as telecommunications and computers; o our ability to develop, manufacture and market innovative products in a rapidly changing technological environment; o our ability to compete in products and prices in an intensely competitive industry; o our ability to maintain and enforce a strong intellectual property portfolio and obtain needed licenses from third parties; o timely completion by customers and suppliers of their Year 2000 programs, accurate assessment of our Year 2000 readiness and of risks associated with its current and past products, and effective implementation of contingency plans and corrective actions; o timely completion of announced acquisitions; o global economic, social and political conditions in the countries in which we and our customers and suppliers operate, including fluctuations in foreign currency exchange rates; o losses or curtailments of purchases from key customers; o our ability to recruit and retain skilled personnel; o availability of raw materials and critical manufacturing equipment; and o realization of savings from announced worldwide corporate restructuring efforts and consolidation of manufacturing operations. For a more detailed discussion of these factors, see the text under the heading "Cautionary Statements Regarding Future Operations" in Item 1 of our annual report on Form 10-K for 1998. The forward-looking statements included in this prospectus are made only as of the date of this prospectus and we undertake no obligation to publicly update the forward-looking statements to reflect subsequent events or circumstances. In this prospectus and in the documents we incorporate by reference, we state our beliefs of future events and our future financial performance. In some cases, you can identify those so-called "forward-looking statements" by words such as "may," "will," "should," "expects," "plans," "anticipates," "believes," "estimates," "predicts," "potential," or "continue" or the negative of those words and other comparable words. You should be aware that those statements are only our predictions. Actual events or results may differ materially. In evaluating those statements, you should specifically consider various factors, including risks. Those factors may cause our actual results to differ materially from any of our forward-looking statements. 1

TEXAS INSTRUMENTS INCORPORATED We are a global semiconductor company and the world's leading designer and supplier of digital signal processors and analog integrated circuits, the engines driving the digitization of electronics. These two types of semiconductor products work together in digital electronic devices such as digital cellular phones. Analog technology converts analog signals like sound, light, temperature and pressure into the digital language of zeros and ones, which can then be processed in real-time by a digital signal processor. Analog integrated circuits also translate digital signals back to analog. Digital signal processors and analog integrated circuits enable a wide range of new products and features for our more than 30,000 customers in commercial, industrial and consumer markets. We are also the world leader in the design and manufacturing of other semiconductor products. Those products include standard logic, application- specific integrated circuits, reduced instruction-set computing microprocessors, and microcontrollers. The semiconductor business comprised 80% of our 1998 revenues when the divested memory business is excluded. Our semiconductor products are used in a diverse range of electronic systems, including digital cell phones, computers, printers, hard disk drives, modems, networking equipment, digital cameras and video recorders, motor controls, autos and home appliances. Products are sold primarily to original-equipment manufacturers and through distributors. Our semiconductor patent portfolio has been established as an ongoing contributor to semiconductor revenues. Revenues generated from sales to our top three semiconductor customers accounted for approximately 24% of total semiconductor revenues in 1998. In addition to semiconductors, we have two other principal segments. The largest, representing 12% of our 1998 revenues when the memory business is excluded, is Materials & Controls (M&C). This business sells electrical and electronic controls, electronic connectors, sensors, radio- frequency identification systems and clad metals into commercial and industrial markets. Revenues generated from sales to our top three M&C customers accounted for approximately 15% of total M&C revenues in 1998. Educational & Productivity Solutions (E&PS) represents 6% of our 1998 revenues when the memory business is excluded, and is a leading supplier of educational and graphing calculators. Revenues generated from sales to our top three E&PS customers accounted for approximately 26% of total E&PS revenues in 1998. In addition, we continue to invest in digital imaging, an emerging business that produces micro- mirror-based devices than enable brightness and clarity in large-screen video displays. We are a Delaware corporation that was organized in 1938. We have our principal executive offices at 12500 TI Boulevard, Dallas, Texas 75366- 0199. Our telephone number is (972) 995-3773. We also have a world wide web site at http://www.ti.com. The information posted on our web site is not incorporated into this prospectus. 2

USE OF PROCEEDS We intend to use the net proceeds from the sale of the securities for working capital and general corporate purposes, including possible redemption or purchase of our existing debt securities. We may also invest the proceeds in certificates of deposit, United States government securities or certain other interest bearing securities. If we decide to use the net proceeds from a particular offering of securities for a specific purpose, we will describe that in a prospectus supplement. RATIO OF EARNINGS TO FIXED CHARGES The following table sets forth our ratio of earnings to fixed charges for each of the years ended December 1994 through 1998 and for nine months ended September 30, 1999. Earnings consist of income (loss) from continuing operations before income taxes, extraordinary items, cumulative effect of accounting changes, equity in net losses of affiliates and fixed charges. Fixed charges consist of interest expense and capitalized interest.

The coverage deficiency was $43 million in 1996. DESCRIPTION OF THE SENIOR DEBT SECURITIES AND THE SUBORDINATED DEBT SECURITIES Our debt securities, consisting of notes, debentures or other evidences of indebtedness, may be issued from time to time in one or more series: o in the case of senior debt securities, under a senior indenture dated as of July 15, 1996 between us and Citibank, N.A., as trustee; and o in the case of subordinated debt securities, under a subordinated indenture dated as of December 16, 1999 between us and Chase Bank of Texas, National Association, as trustee. The senior indenture and the subordinated indenture are included as exhibits to the registration statement of which this prospectus is a part. Because the following is only a summary of the indentures and the debt securities, it does not contain all information that you may find useful. For further information about the indentures and the debt securities, you should read the indentures. As used in this Section of the prospectus and under captions "Description of Warrants," "Description of Purchase Contracts" and "Description of Units," the terms we, us and our mean Texas Instruments Incorporated only, and not subsidiaries of Texas Instruments Incorporated. General The senior debt securities will constitute unsecured and unsubordinated obligations of ours and the subordinated debt securities will constitute unsecured and subordinated obligations of ours. A detailed description of the subordination provisions is provided below under the caption "Certain Terms of the subordinated debt securities -- Subordination". In general, however, if we declare bankruptcy the senior debt securities will be paid in full before the subordinated debt securities will receive anything. We conduct some of our operations through subsidiaries. Consequently, our ability to pay our obligations, including our obligation to pay principal or interest on the debt securities, to pay the debt securities at maturity or upon redemption or to buy the debt securities may depend upon our subsidiaries repaying investments and advances we have made to them, and upon our subsidiaries' earnings and their distributing those earnings to us. Our subsidiaries are separate and distinct legal entities and have no 3

obligation, contingent or otherwise, to pay any amounts due on the debt securities or to make funds available to us to do so. Our subsidiaries' ability to pay dividends or make other payments or advances to us will depend upon their operating results and will be subject to applicable laws and contractual restrictions. The indentures will not limit our subsidiaries' ability to enter into other agreements that prohibit or restrict dividends or other payments or advances to us. You should look in the prospectus supplement for the following terms of the debt securities being offered: o the debt securities' designation; o the aggregate principal amount of the debt securities; o the percentage of their principal amount (i.e. price) at which the debt securities will be issued; o the date or dates on which the debt securities will mature and the right, if any, to extend such date or dates; o the rate or rates, if any, per year, at which the debt securities will bear interest, or the method of determining such rate or rates; o the date or dates from which such interest will accrue, the interest payment dates on which such interest will be payable or the manner of determination of such interest payment dates and the record dates for the determination of holders to whom interest is payable on any interest payment dates; o the right, if any, to extend the interest payment periods and the duration of that extension; o provisions for a sinking fund purchase or other analogous fund, if any; o the period or periods, if any, within which, the price or prices at which, and the terms and conditions upon which the debt securities may be redeemed, in whole or in part, at our option or at your option; o the form of the debt securities; o any provisions for payment of additional amounts for taxes and any provision for redemption, if we must pay such additional amounts in respect of any debt security; o the terms and conditions, if any, upon which we may have to repay the debt securities early at your option and the price or prices in the currency or currency unit in which the debt securities are payable; o the currency, currencies or currency units for which you may purchase the debt securities and the currency, currencies or currency units in which principal and interest, if any, on the debt securities may be payable; o the terms and conditions, if any, pursuant to which the debt securities may be exchanged for the cash value of other securities issued by us or by a third party; and o any other terms of the debt securities, including any additional events of default or covenants provided for with respect to the debt securities, and any terms which may be required by or advisable under applicable laws or regulations. You may present debt securities for exchange and you may present registered debt securities for transfer in the manner, at the places and subject to the restrictions set forth in the debt securities and the prospectus supplement. We will provide you those services without charge, although you may have to pay any tax or other governmental charge payable in connection with any exchange or transfer, as set forth in the indenture. You may also transfer debt securities in bearer form by delivery. Debt securities will bear interest at a fixed rate or a floating rate. Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate (Original Issue Discount Securities) may be sold at a discount below their stated principal amount. Special United States federal income tax considerations applicable to any such discounted debt securities or to certain debt securities issued at par which are treated as having 4

been issued at a discount for United States federal income tax purposes will be described in the relevant prospectus supplement. We may issue debt securities with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices or indices. You may receive a payment of principal on any principal payment date, or a payment of interest on any interest payment date, that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value on such dates of the applicable currency, security or basket of securities, commodity or index. Information as to the methods for determining the amount of principal or interest payable on any date, the currencies, securities or baskets of securities, commodities or indices to which the amount payable on such date is linked and certain additional tax considerations will be set forth in the applicable prospectus supplement. Certain Terms of the Senior Debt Securities Certain Covenants Certain Definitions. The term "attributable debt" in respect of a sale and leaseback transaction means, at the time of determination, the present value (discounted at the interest rate implicit in the lease or, if it is not practicable to determine such rate, then at our incremental borrowing rate determined in accordance with generally accepted accounting principles) of the obligation of the lessee for net rental payments during the remaining term of any lease. The term "consolidated net tangible assets" means, at any date, the total assets appearing on our audited annual consolidated balance sheet and that of our subsidiaries for the most recently completed fiscal year, prepared in accordance with generally accepted accounting principles, less all current liabilities as shown on such balance sheet, and intangible assets. The term "funded debt" means all debt whether incurred, assumed or guaranteed, including purchase money indebtedness, maturing by its terms more than one year from the date of creation thereof or which is renewable or extendable at the sole option of the obligor in such manner that it may become payable more than one year from the date of creation thereof. The term "principal manufacturing property" means each of our, or our subsidiary's manufacturing or processing plant or facility located in the United States of America (other than its territories and possessions) or Puerto Rico, except any such manufacturing or processing plant or facility which the board of directors by resolution reasonably determines not to be of material importance to the total business conducted by us and our consolidated subsidiaries. The term "restricted subsidiary" means: o any of our subsidiaries which owns or is the lessee of any principal manufacturing property; provided, however, that the term "restricted subsidiary" shall not include any subsidiary primarily engaged in financing our operations or the operations of our subsidiaries or both, or any subsidiary acquired or organized for the purpose of business acquisitions; or o any other subsidiary which is hereafter designated by the board of directors as a restricted subsidiary. Restrictions on Liens. The senior indenture provides that, unless as may otherwise be indicated by a supplemental indenture, we will not nor will we permit any restricted subsidiary to issue or assume any debt for money borrowed (which, including guarantees of debt for borrowed money, we refer to as "debt"), if the debt is secured by a mortgage, pledge, lien or other encumbrance (which we refer to as a "mortgage") upon any principal manufacturing property or on any shares of stock or debt of any restricted subsidiary (whether such principal manufacturing property, shares of stock or debt is now owned or subsequently acquired) without in any such case effectively providing that the senior debt securities (together with any other debt security ranking equally with the senior debt securities) shall be secured equally and ratably with the debt. The foregoing restrictions shall not apply to: o mortgages on property existing at the time of or within 120 days after acquisition of the property and certain purchase money 5

mortgages; o mortgages on property of a corporation existing at the time that corporation is merged into or consolidated with us or a restricted subsidiary; o mortgages in favor of the United States or any political subdivision or any instrumentality thereof, to secure certain payments pursuant to any contract or statute or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of construction of the property subject to the mortgages; o any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any mortgage referred to in bullet points one to three above; and o mortgages securing the indebtedness of a restricted subsidiary to us or to another restricted subsidiary. Restrictions on Sale and Leaseback Transactions. The senior indenture provides that, unless as may otherwise be indicated by a supplemental indenture, we will not, and will not permit any restricted subsidiary to, enter into any lease longer than three years covering any principal manufacturing property that is sold to any other person in connection with such lease unless the proceeds from such sale or transfer shall be at least equal to the fair value of such property as determined by resolution by our board of directors and either: o we or such restricted subsidiary would be entitled, pursuant to the "Restrictions on Liens" described above, to incur debt secured by a mortgage on the principal manufacturing property involved in an amount at least equal to the attributable debt in respect of the principal manufacturing property without equally and ratably securing the senior debt securities, provided, that such attributable debt shall thereupon be deemed to be Debt subject to the provisions of such restrictions on liens; or o within a period commencing twelve months prior to the consummation of the sale and leaseback transaction and ending twelve months after consummation of such transaction, we or such restricted subsidiary has expended or will expend for principal manufacturing property an amount equal to o the proceeds of such sale and leaseback transaction and we elect to designate such amount as a credit against such transaction, or o a part of the proceeds of such sale and leaseback transaction and we elect to designate such amount as a credit against such transaction and treat an amount equal to the remainder of the proceeds as provided in clause directly below, or o such attributable debt (less any amount elected under the clause directly above) is applied within 120 days after the transaction to the retirement of funded debt, or is considered attributable debt for purposes of the calculation of exempted debt and, after giving effect to the exempted debt, the exempted debt does not exceed 5% of consolidated net tangible assets. Exempted Debt. The senior indenture provides that, notwithstanding the restrictions on mortgages and sale and leaseback transactions described above, we and our restricted subsidiaries may, in addition to amounts permitted under such restrictions, create debt secured by mortgages, or enter into sale and leaseback transactions, which would otherwise be subject to the foregoing restrictions, without equally and ratably securing the senior debt securities and without any obligation to make expenditures for principal manufacturing property or to retire any debt, provided, that after giving effect thereto, the aggregate additional outstanding amount of such debt secured by mortgage plus attributable debt resulting from such sale and leaseback transactions does not exceed 5% of consolidated net tangible assets. Consolidation, Merger and Sale or Conveyance. We may not consolidate with, merge with or into, or sell, or convey (including by way of lease) all or substantially all of our assets to any person or permit any person to merge with or into us unless: 6

o we are the continuing person or the person formed by such consolidation or into which we are merged or that acquired or leased our property and assets shall be a corporation or entity organized and validly existing under the laws of the United States of America or any jurisdiction thereof (or, any entity not organized under such laws which agrees, in a form satisfactory to the trustee, to submit to the jurisdiction of the United States district court for the Southern District of New York, and to indemnify and hold harmless the holders of the debt securities against certain taxes and expenses) and shall expressly assume, by a supplemental indenture, executed and delivered to the trustee, all of our obligations on all of the debt securities and under the indenture; o immediately after giving effect to such transaction, no default or event of default shall have occurred and be continuing; and o we deliver to the trustee an officers' certificate and opinion of counsel, in each case stating that such consolidation, merger, or transfer and such supplemental indenture complies with this provision and that all conditions precedent provided for in the indenture and the debt securities relating to such transaction have been complied with. Events of Default An event of default for any series of senior debt securities is defined under the senior indenture as being: o our default in the payment of principal or premium on the senior debt securities of such series when due and payable whether at maturity, upon acceleration, redemption, or otherwise; o our default in the payment of interest on any senior debt securities of such series when due and payable, if that default continues for a period of 30 days; o our default in the performance of or breach of any of our other covenants or agreements in the senior indenture applicable to senior debt securities of such series, other than a covenant breach of which is specifically dealt with elsewhere in the senior indenture, and that default or breach continues for a period of 90 consecutive days after we receive written notice from the trustee or from the holders of 25% or more in aggregate principal amount of the senior debt securities of such series; o our default in the performance of any other covenant, if that default is an Event of Default under any supplemental indenture or in the resolution of the Board of Directors under which such series of senior debt securities is issued or in the form of Security for such series; o a court having jurisdiction enters a decree or order for: o relief in respect of us in an involuntary case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect; o appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official of us or for all or substantially all of our property and assets; or o the winding up or liquidation of our affairs and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days. o we: o commence a voluntary case under any applicable bankruptcy, insolvency, or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law; o consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator, or similar official of ours for all or substantially all of our property and assets; or o effect any general assignment for the 7

benefit of creditors. If an event of default other than an event of default specified in the last two bullet points above or an event of default which is in respect of all outstanding senior debt securities under the third or fourth bullet point above, occurs with respect to an issue of senior debt securities and is continuing under the indenture, then, and in each and every such case, either the trustee or the holders of not less than 25% in aggregate principal amount of such series then outstanding under the indenture (each such series voting as a separate class) by written notice to us and to the trustee, if such notice is given by the holders, may, and the trustee at the request of such holders shall, declare the principal amount of and accrued interest, if any, on such senior debt securities to be immediately due and payable. Unless otherwise specified in the prospectus supplement relating to a series of debt securities originally issued at a discount, the amount due upon acceleration shall include only the original issue price of the debt securities, the amount of original issue discount accrued to the date of acceleration and accrued interest, if any. Upon a declaration of acceleration, such principal amount of and accrued interest, if any, on such senior debt securities shall be immediately due and payable. If an event of default specified in the last two bullet points above or an event of default which is in respect of all outstanding senior debt securities under the third or fourth bullet point above, occurs with respect to us, either the trustee or the holders of not less than 25% in aggregate principal amount of the securities of such series then outstanding (treated as one class) may, by written notice to us and to the trustee, if such notice is given by the holders, declare the entire principal amount of, and accrued interest, if any, on each issue of senior debt security then outstanding to be immediately due and payable. Upon certain conditions such declarations above may be rescinded and annulled and past defaults may be waived by the holders of a majority in aggregate principal amount of all the securities of such series affected by the default, each series voting as a separate class, (or, of all the senior debt securities, as the case may be, voting as a single class). Furthermore, subject to various provisions in the senior indenture, the holders of at least a majority in aggregate principal amount of an issue of senior debt securities by notice to the trustee, may waive an existing default or event of default with respect to such senior debt securities and its consequences, except a default in the payment of principal of or interest on such senior debt securities or in respect of a covenant or provision of the indenture which cannot be modified or amended without the consent of the holders of each such senior debt securities. Upon any such waiver, such default shall cease to exist, and any event of default with respect to such senior debt securities shall be deemed to have been cured, for every purpose of the senior indenture; but no such waiver shall extend to any subsequent or other default or event of default or impair any right consequent thereto. For information as to the waiver of defaults, see "--Modification and Waiver." The holders of at least a majority in aggregate principal amount of an issue of senior debt securities may direct the time, method, and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such senior debt securities. However, the trustee may refuse to follow any direction that conflicts with law or the senior indenture, that may involve the trustee in personal liability, or that the trustee determines in good faith may be unduly prejudicial to the rights of holders of such issue of senior debt securities not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from holders of such issue of senior debt securities. A holder may not pursue any remedy with respect to the indenture or any series of senior debt securities unless: o the holder gives the trustee written notice of a continuing event of default; o the holders of at least 25% in aggregate principal amount of such series of senior debt securities make a written request to the trustee to pursue the remedy in respect of such event of default; o the requesting holder or holders offer the trustee indemnity satisfactory to the trustee against any costs, liability, or expense; o the trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 8

o during such 60-day period, the holders of a majority in aggregate principal amount of such series of senior debt securities do not give the trustee a direction that is inconsistent with the request. These limitations, however, do not apply to the right of any holder of a debt security to receive payment of the principal of or interest, if any, on such senior debt security, or to bring suit for the enforcement of any such payment, on or after the due date for the senior debt securities, which right shall not be impaired or affected without the consent of the holder. The senior indenture requires certain of our officers to certify, on or before a fixed date in each year in which any security is outstanding, as to their knowledge of our compliance with all conditions and covenants under the senior indenture. Discharge and Defeasance The senior indenture provides that, unless the terms of any series of senior debt securities provides otherwise, we may discharge our obligations with respect to an issue of senior debt securities and the indenture with respect to such series of senior debt securities if: o we pay or cause to be paid, as and when due and payable, the principal of and any interest on all securities of such series outstanding under the indenture; o all senior debt securities of such series previously authenticated and delivered with certain exceptions, have been delivered to the trustee for cancellation and we have paid all sums payable by it under the indenture; or o o the senior debt securities of such series mature within one year or all of them are to be called for redemption within one year under arrangements satisfactory to the trustee for giving the notice of redemption; o we irrevocably deposit in trust with the trustee, as trust funds solely for the benefit of the holders of the senior debt securities of such series, for that purpose, the entire amount in cash or, in the case of any series of senior debt securities payments on which may only be made in US dollars, U.S. government obligations (maturing as to principal and interest in such amounts and at such times as will insure the availability of cash sufficient), after payment of all federal, state and local taxes or other charges and assessments in respect thereof payable by the trustee, to pay principal of and interest on the senior debt securities of such series to maturity or redemption, as the case may be, and to pay all other sums payable by it under the senior indenture. With respect to the first and second bullet points, only our obligations to compensate and indemnify the trustee and our right to recover unclaimed money held by the trustee under the indenture shall survive. With respect to the third bullet point, certain rights and obligations under the senior indenture (such as our obligation to maintain an office or agency in respect of such senior debt securities, to have moneys held for payment in trust, to register the transfer or exchange of such senior debt securities, to deliver such senior debt securities for replacement or to be canceled, to compensate and indemnify the trustee and to appoint a successor trustee, and our right to recover unclaimed money held by the trustee) shall survive until such senior debt securities are no longer outstanding. Thereafter, only our obligations to compensate and indemnify the trustee, and our right to recover unclaimed money held by the trustee shall survive. Unless the terms of any series of senior debt securities provide otherwise, on the 121st day after the date of deposit of the trust funds with the trustee, we will be deemed to have paid and will be discharged from any and all obligations in respect of the series of senior debt securities provided for in the funds, and the provisions of the senior indenture will no longer be in effect with respect to such senior debt securities ("legal defeasance"); provided that the following conditions shall have been satisfied: o we have irrevocably deposited in trust with the trustee as trust funds solely for the benefit of the holders of the senior debt securities of such series, for payment of the principal of and interest on the senior debt securities of such series, cash in an amount or, in the case of any series of senior debt securities payments on which can only be made in US dollars, U.S. government obligations (maturing 9

as to principal and interest at such times and in such amounts as will insure the availability of cash) or a combination thereof sufficient (in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the trustee), after payment of all federal, state and local taxes or other charges and assessments in respect thereof payable by the trustee, to pay and discharge the principal of and accrued interest on the senior debt securities of such series to maturity or earlier redemption, as the case may be; o such deposit will not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which we are a party or by which we are bound; o no default or event of default with respect to the senior debt securities of such series shall have occurred and be continuing on the date of such deposit; o we shall have delivered to the trustee either an officers' certificate and an opinion of counsel that the holders of the senior debt securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of our exercising our option under this provision of the indenture and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred or a ruling by the Internal Revenue Service to the same effect; and o we have delivered to the trustee an officers' certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in the indenture relating to the defeasance contemplated of the senior debt securities of such series have been complied with. Subsequent to the legal defeasance above, certain rights and obligations under the senior indenture (such as our obligation to maintain an office or agency in respect of such senior debt securities, to have moneys held for payment in trust, to register the exchange of such senior debt securities, to deliver such debt securities for replacement or to be canceled, to compensate and indemnify the trustee and to appoint a successor trustee, and our right to recover unclaimed money held by the trustee) shall survive until such senior debt securities are no longer outstanding. After such senior debt securities are no longer outstanding, only our obligations to compensate and indemnify the trustee and our right to recover unclaimed money held by the trustee shall survive. Modification and Waiver We and the trustee may amend or supplement the senior indenture or the senior debt securities without the consent of any holder: o to convey, mortgage or pledge any assets to the trustee as security for the securities of one or more series; o to evidence the succession of another corporation to us, and the assumption by such successor corporation of our covenants, agreements and obligations under the senior indenture; o to cure any ambiguity, defect, or inconsistency in the senior indenture; provided that such amendments or supplements shall not adversely affect the interests of the holders in any material respect; o to comply with the provisions described under "--Certain Covenants --Consolidation, Merger and Sale or Conveyance; o to evidence and provide for the acceptance of appointment hereunder by a successor trustee, or to make such changes as shall be necessary to provide for or facilitate the administration of the trusts in the senior indenture by more than one trustee; o to establish the form or forms or terms of the senior debt securities as permitted by the senior indenture; o to make any change that does not adversely affect the rights of any holder; 10

o to add to our covenants such new covenants, restrictions, conditions or provisions for the protection of the holders, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default; or o to make any change so long as no senior debt securities are outstanding. Subject to certain conditions, modifications and amendments of the senior indenture may be made by us and the trustee with the written consent of the holders of a majority in principal amount of such series of senior debt securities affected, and compliance by us with any provision of the indenture with respect to such series of senior debt securities may be waived by written notice to the trustee by the holders of a majority in principal amount of such series of senior debt securities outstanding; provided, however, that each affected holder must consent to any modification, amendment or waiver that, o changes the stated maturity of the principal of, or any installment of interest on, any senior debt securities of such series; o reduces the principal amount of, or premium, if any, or interest on, any senior debt securities of such series; o changes the place or currency of payment of principal of, or premium, if any, or interest on, any senior debt securities of such series; o changes the provisions for calculating the optional redemption price, including the definitions relating thereto; o changes the provisions relating to the waiver of past defaults or change or impair the right of holders to receive payment or to institute suit for the enforcement of any payment of any senior debt securities of such series on or after the due date therefor; o reduces the above-stated percentage of outstanding senior debt securities of such series the consent of whose holders is necessary to modify or amend or to waive certain provisions of or defaults under the indenture; o waives a default in the payment of principal of or interest on the senior debt securities; o adversely affects the rights of such holder under any mandatory redemption or repurchase provision or any right of redemption or repurchase at the option of such holder; or o modifies any of the provisions of this paragraph, except to increase any required percentage or to provide that certain other provisions cannot be modified or waived with the consent of the holder of each senior debt security of such series affected by the modification. It shall not be necessary for the consent of the holders under this section of the indenture to approve the particular form of any proposed amendment, supplement, or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement, or waiver under this section of the indenture becomes effective, the trustee must give to the holders affected thereby certain notice briefly describing the amendment, supplement, or waiver. We will mail supplemental indentures to holders upon request. Any failure by the trustee to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver. No Personal Liability of Incorporators, Stockholders, Officers, Directors The senior indenture provides that no recourse shall be had under or upon any obligation, covenant, or agreement of ours in the indenture or any supplemental indenture, or in any of the senior debt securities or because of the creation of any indebtedness represented thereby, against any incorporator, stockholder, officer, director of ours or of any successor person thereof under any law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. Each holder, by accepting the senior debt securities, waives and releases all such liability. 11

Concerning the Trustee The senior indenture provides that, except during the continuance of a default, the trustee will not be liable, except for the performance of such duties as are specifically set forth in the senior indenture. If an event of default has occurred and is continuing, the trustee will exercise such rights and powers vested in it under the senior indenture and will use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person's own affairs. Governing Law The indentures and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York. The Trustees We may have normal banking relationships with the trustees under the indentures in the ordinary course of business. Certain Terms of the Subordinated Debt Securities Other than the terms of the subordinated indenture and subordinated debt securities relating to subordination, or otherwise as described in the prospectus supplement relating to a particular series of subordinated debt securities, the terms of the subordinated indenture and subordinated debt securities are identical, in all material respects, to the terms of the senior indenture and senior debt securities. Subordination The indebtedness evidenced by the subordinated debt securities is subordinate to the prior payment in full of all Senior Indebtedness, as defined in the subordinated indenture. During the continuance beyond any applicable grace period of any default in the payment of principal, premium, interest or any other payment due on any senior indebtedness, we may not make any payment of principal of, or premium, if any, or interest on the subordinated debt securities. In addition, upon any distribution of our assets upon any dissolution, winding up, liquidation or reorganization, the payment of the principal of, or premium, if any, and interest on the subordinated debt securities is to be subordinated to the extent provided in the subordinated indenture in right of payment to the prior payment in full of all senior indebtedness. Because of this subordination, if we dissolve or otherwise liquidate, holders of senior indebtedness may receive more, ratably, and holders of our subordinated debt securities may receive less, ratably, than our other creditors. The subordination provisions do not prevent the occurrence of an event of default under the subordinated indenture. The term "Senior Indebtedness" means the principal of, premium, if any, interest on, and any other payment due pursuant to any of the following, whether outstanding today or incurred by us in the future: o all of our indebtedness for money borrowed, including any indebtedness secured by a mortgage or other lien which is (1) given to secure all or part of the purchase price of property subject to the mortgage or lien, whether given to the vendor of that property or to another lender, or (2) existing on property at the time we acquire it; o all of our indebtedness evidenced by notes, debentures, bonds or other securities sold by us for money; o all of our lease obligations which are capitalized on our books in accordance with generally accepted accounting principles; o all indebtedness of others of the kinds described in the first two bullet points above and all lease obligations of others of the kind described in the third bullet point above that we, in any manner, assume or guarantee or that we in effect guarantee through an agreement to purchase, whether that agreement is contingent or otherwise; and o all renewals, extensions or refundings of indebtedness of the kinds described in the first, second or fourth bullet point above and all renewals or extensions of leases of the kinds described in the third or fourth bullet point above; 12

unless, in the case of any particular indebtedness, lease, renewal, extension or refunding, the instrument or lease creating or evidencing it or the assumption or guarantee relating to it expressly provides that such indebtedness, lease, renewal, extension or refunding is not superior in right of payment to the subordinated debt securities. Our senior debt securities constitute Senior Indebtedness for purposes of the subordinated debt indenture. DESCRIPTION OF WARRANTS General We may issue warrants to purchase securities or rights of ours, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies or indices, or securities of other issuers or any combination of the foregoing. Warrants may be issued independently or together with any securities and may be attached to or separate from such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The following sets forth certain general terms and provisions of the warrants offered hereby. Further terms of the warrants and the applicable warrant agreement will be set forth in the applicable prospectus supplement. The applicable prospectus supplement will describe the following terms of any warrants in respect of which this prospectus is being delivered: o the title of such warrants; o the aggregate number of such warrants; o the price or prices at which such warrants will be issued; o the currency or currencies, including composite currencies, in which the price of such warrants may be payable; o the securities or rights of ours, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies or indices, or securities of other issuers or any combination of the foregoing purchasable upon exercise of such warrants; o the price at which and the currency or currencies, including composite currencies, in which the securities purchasable upon exercise of such warrants may be purchased; o the date on which the right to exercise such warrants shall commence and the date on which such right shall expire; o if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time; o if applicable, the designation and terms of the securities with which such warrants are issued and the number of such warrants issued with each such security; o if applicable, the date on and after which such warrants and the related securities will be separately transferable; o information with respect to book-entry procedures, if any; o if applicable, a discussion of certain United States Federal income tax considerations; and o any other terms of such warrants, including terms, procedures and limitations relating to the exchange and exercise of such warrants. 13

DESCRIPTION OF PURCHASE CONTRACTS We may issue purchase contracts for the purchase or sale of: o our securities or securities of an entity unaffiliated or affiliated with us, a basket of such securities, an index or indices of such securities or any combination of the above as specified in the applicable prospectus supplement; o currencies or composite currencies; or o commodities. Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, all as set forth in the applicable prospectus supplement. We must, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value thereof or, in the case of underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract. Purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, the pre-paid purchase contracts will be issued under one of the indentures. DESCRIPTION OF UNITS As specified in the applicable prospectus supplement, units will consist of one or more purchase contracts, warrants or debt securities, or any combination thereof. Reference is made to the applicable prospectus supplement for: o all terms of the units and of the purchase contracts, warrants, debt securities, or any combination thereof, comprising the units, including whether and under what circumstances the securities comprising the units may or may not be traded separately; o a description of the terms of any unit agreement governing the units; and o a description of the provisions for the payment, settlement, transfer or exchange of the units. GLOBAL SECURITIES We may issue the debt securities, warrants, purchase contracts and units of any series in the form of one or more fully registered global securities that will be deposited with a depositary or with a nominee for a depositary identified in the prospectus supplement relating to such series and registered in the name of the depositary or its nominee. In that case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of outstanding registered securities of the series to be represented by such global securities. Unless and until the depositary exchanges a global security in whole for securities in definitive registered form, the global security may not be transferred except as a whole by the depositary to a nominee of the depositary or by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any of its nominees to a successor of the depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any portion of a series of securities to be represented by a global security will be described in the prospectus supplement relating to such series. We anticipate that the following provisions will apply to all depositary arrangements. 14

Ownership of beneficial interests in a global security will be limited to persons that have accounts with the depositary for such global security known as "participants" or persons that may hold interests through such participants. Upon the issuance of a global security, the depositary for such global security will credit, on its book-entry registration and transfer system, the participants' accounts with the respective principal or face amounts of the securities represented by such global security beneficially owned by such participants. The accounts to be credited shall be designated by any dealers, underwriters or agents participating in the distribution of such securities. Ownership of beneficial interests in such global security will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for such global security (with respect to interests of participants) and on the records of participants (with respect to interests of persons holding through participants). The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to own, transfer or pledge beneficial interests in global securities. So long as the depositary for a global security, or its nominee, is the registered owner of such global security, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the securities represented by such global security for all purposes under the applicable indenture, warrant agreement, purchase contract, or unit agreement. Except as set forth below, owners of beneficial interests in a global security will not be entitled to have the securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of such securities in definitive form and will not be considered the owners or holders thereof under the applicable indenture, warrant agreement, purchase contract, or unit agreement. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of the depositary for such global security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, purchase contract, or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a global security desires to give or take any action which a holder is entitled to give or take under the applicable indenture, warrant agreement, purchase contract, or unit agreement, the depositary for such global security would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participants to give or take such action or would otherwise act upon the instructions of beneficial owners holding through them. Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants, purchase contracts, preferred securities, or units, represented by a global security registered in the name of a depositary or its nominee will be made to such depositary or its nominee, as the case may be, as the registered owner of such global security. None of us, the trustees, the warrant agents, the unit agents or any of our other agents, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in such global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. We expect that the depositary for any securities represented by a global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or commodities to holders in respect of such global security, will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in such global security as shown on the records of such depositary. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such participants. If the depositary for any securities represented by a global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and we do not appoint a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934 within 90 15

days, we will issue such securities in definitive form in exchange for such global security. In addition, we may at any time and in our sole discretion determine not to have any of the securities of a series represented by one or more global securities and, in such event, will issue securities of such series in definitive form in exchange for all of the global security or securities representing such securities. Any securities issued in definitive form in exchange for a global security will be registered in such name or names as the depositary shall instruct the relevant trustee, warrant agent or other relevant agent of ours. We expect that such instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in such global security. PLAN OF DISTRIBUTION We may sell the securities being offered hereby in four ways: o directly to purchasers; o through agents; o through underwriters; and o through dealers. We may directly solicit offers to purchase securities, or we may designate agents to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act of 1933 and describe any commissions we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business. If any underwriters are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement with them at the time of sale to them and we will set forth in the prospectus supplement relating to such offering their names and the terms of our agreement with them. If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. Remarketing firms, agents, underwriters and dealers may be entitled under agreements which they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act of 1933, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business. If so indicated in the prospectus supplement, we will authorize agents and underwriters to solicit offers by certain institutions to purchase debt securities from us at the public offering price set forth in the prospectus supplement pursuant to Delayed Delivery Contracts ("Contracts") providing for payment and delivery on the date stated in the prospectus supplement. Such Contracts will be subject only to those conditions set forth in the prospectus supplement. A commission indicated in the prospectus supplement will be paid to underwriters and agents soliciting purchases of debt securities pursuant to Contracts accepted by us. In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. 16

Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities, and may end any of these activities at any time. Any underwriter, agent or dealer utilized in the initial offering of securities will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer. LEGAL MATTERS The validity of the offered securities will be passed upon for us by Davis Polk & Wardwell, New York, New York.

PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 14. Other Expenses of Issuance and Distribution All of the expenses in connection with the offering are as follows: Securities and Exchange Commission registration fee................ $ 237,600 * Legal fees and expenses............................................ 125,000 * Printing and engraving fees........................................ 20,000 * Accountants' fees and expenses..................................... 25,000 * Miscellaneous...................................................... 10,000 * ---------- Total......................................................... $ 417,600 * ========== - --------- * Estimated Item 15. Indemnification of Directors and Officers. The General Corporation Law of the State of Delaware, at Section 145, provides, in pertinent part, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or complete action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as the director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. In addition, the indemnification of expenses, including attorneys' fees, is allowed in derivative actions, except no indemnification is allowed in respect to any claim, issue or matter as to which any such person has been adjudged to be liable to the corporation, unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought decides that indemnification is proper. To the extent that any such person succeeds on the merits or otherwise, he shall be indemnified against expenses, including attorney's fees, actually and reasonably incurred by him in connection therewith. The determination that the person to be indemnified met the applicable standard of conduct, if not made by a court, is made by the directors of the corporation by a majority vote of the directors not party to such an action, suit or proceeding even though less than a quorum, by a committee of such directors designated by majority vote of such directors even though less than a quorum, or if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion or by the stockholders. Expenses may be paid in advance upon the receipt, in the case of officers and directors, of undertakings to repay such amount if it shall ultimately be determined that the person is not entitled to be indemnified by the corporation as authorized in this section. A corporation may purchase indemnity insurance. The above described indemnification and advancement of expenses, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and inure to the benefit of such person's heirs, executors and administrators. Article VI, Section 2 of the Texas Instruments Incorporated By-laws provides that Texas Instruments Incorporated shall indemnify its officers and directors for such expenses, judgments, fines and amounts paid in settlement to the full extent permitted by the laws of the State of Delaware. Section 102(b)(7) of the General Corporation Law of the State of Delaware, as amended, permits a II-1

corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware, or (iv) for any transaction from which the director derived an improper personal benefit. Article Seventh of Texas Instruments Incorporated Restated Certificate of Incorporation contains such a provision. Under insurance policies of Texas Instruments Incorporated, directors and officers of Texas Instruments Incorporated may be indemnified against certain losses arising from certain claims, including claims under the Securities Act of 1933, which may be made against such persons by reason of their being such directors or officers.

Item 17. Undertakings. The undersigned registrant hereby undertakes: 1. (a) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the "Securities Act"); (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that subparagraphs (a) (i) and (a) (ii) shall not apply to the extent that information required to be included in a post-effective amendment by those subparagraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act") that are incorporated by reference in the Registration Statement. (b) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. 2. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act II-3

that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 3. If the securities to be registered are to be offered at competitive bidding, the undersigned registrant hereby undertakes (1) to use its best efforts to distribute prior to the opening of bids, to prospective bidders, underwriters, and dealers, a reasonable number of copies of a prospectus which at that time meets the requirements of Section 10(a) of the Securities Act, and relating to the securities offered at competitive bidding, as contained in the Registration Statement, together with any supplements thereto, and (2) to file an amendment to the Registration Statement reflecting the results of bidding, the terms of the reoffering and related matters to the extent required by the applicable form, not later than the first use, authorized by the issuer after the opening of bids, of a prospectus relating to the securities offered at competitive bidding, unless no further public offering of such securities by the issuer and no reoffering of such securities by the purchasers is proposed to be made. 4. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

     From time to time, Texas Instruments Incorporated, a Delaware corporation,
may enter into one or more underwriting agreements that provide for the sale of
designated securities to the several underwriters named therein. The standard
provisions set forth herein may be incorporated by reference in any such
underwriting agreement (an "Underwriting Agreement"). The Underwriting
Agreement, including the provisions incorporated therein by reference, is
herein referred to as this Agreement. Unless otherwise defined herein, terms
defined in the Underwriting Agreement are used herein as therein defined.

                                      I.

     The Company proposes to issue and sell certain of its debt securities
("the Debt Securities") issuable under an indenture dated as of July 15, 1996
(the "Senior Indenture") between the Company and Citibank, N.A., as trustee
(the "Senior Indenture Trustee"), and an indenture dated as of December 16,
1999 (the "Subordinated Indenture") between the Company and Chase Bank of
Texas, National Association, as trustee (the "Subordinated Indenture Trustee")
(together the "Trustee" and "Indenture"), the applicable indenture of which
shall be identified in the Underwriting Agreement, in one or more offerings on
terms determined at the time of sale. The Debt Securities will have varying
designations, maturities, principal amounts, rates and times of payment of
interest, selling prices, and redemption terms.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement including a prospectus relating to the
Debt Securities and has filed with, or mailed for filing to, the Commission a
prospectus supplement specifically relating to the Offered Debt Securities
pursuant to Rule 424 under the Securities Act of 1933. The term "Registration
Statement" means the registration statement, including the exhibits thereto, as
amended to the date of the Underwriting Agreement. The term "Basic Prospectus"
means the prospectus included in the Registration Statement. The term
"Prospectus" means the Basic Prospectus together with the prospectus supplement
or supplements specifically relating to Debt Securities then being offered (the
"Offered Debt Securities"), as filed with, or mailed for filing to, the
Commission pursuant to Rule 424. The term "preliminary prospectus" means a
preliminary prospectus supplement specifically relating to the Offered Debt
Securities


together with the Basic Prospectus. As used herein, the terms "Registration Statement", "Basic Prospectus", "Prospectus" and "preliminary prospectus" shall include in each case the material, if any, incorporated by reference therein. The term "Underwriters' Securities" means the Offered Debt Securities to be purchased by the Underwriters herein. The term "Contract Securities" means the Offered Debt Securities, if any, to be purchased pursuant to the delayed delivery contracts referred to below. II. If the Prospectus provides for sales of Offered Debt Securities pursuant to delayed delivery contracts, the Company hereby authorizes the Underwriters to solicit offers to purchase Contract Securities on the terms and subject to the conditions set forth in the Prospectus pursuant to delayed delivery contracts substantially in the form of Schedule I attached hereto ("Delayed Delivery Contracts") but with such changes therein as the Company may authorize or approve. Delayed Delivery Contracts are to be with institutional investors approved by the Company and of the types set forth in the Prospectus. On the Closing Date (as hereinafter defined), the Company will pay the Manager as compensation, for the accounts of the Underwriters, the fee set forth in the Underwriting Agreement in respect of the principal amount of Contract Securities. The Underwriters will not have any responsibility in respect of the validity or the performance of Delayed Delivery Contracts. If the Company executes and delivers Delayed Delivery Contracts with institutional investors, the Contract Securities shall be deducted from the offered Debt Securities to be purchased by the several Underwriters and the aggregate principal amount to be purchased by each Underwriter shall be reduced pro rata in proportion to the principal amount of Offered Debt Securities set forth opposite each Underwriter's name in the Underwriting Agreement, except to the extent that the Manager determines that such reduction shall be otherwise and so advises the Company. III. The Company is advised by the Manager that the Underwriters propose to make a public offering of their respective portions of the Underwriters' Securities as soon after this Agreement is entered into as in the Manager's judgment is advisable. The terms of the public offering of the Underwriters' Securities are set forth in the Prospectus. IV. 2

Payment for the Underwriters' Securities shall be made by certified or official bank check or checks payable to the order of the Company in New York Clearing House funds at the time and place set forth in the Underwriting Agreement, upon delivery to the Manager for the respective accounts of the several Underwriters of the Underwriters' Securities registered in such names and in such denominations as the Manager shall request in writing not less than two full business days prior to the date of delivery. The time and date of such payment and delivery with respect to the Underwriters' Securities are herein referred to as the Closing Date. V. The several obligations of the Underwriters hereunder are subject to the following conditions: (a) No stop order suspending the effectiveness of the Registration Statement shall be in effect, and no proceedings for such purpose shall be pending before or threatened by the Commission and there shall have been no material adverse change (not in the ordinary course of business) in the condition of the Company and its subsidiaries, taken as a whole, from that set forth in or contemplated by the Registration Statement and the Prospectus; and the Underwriters shall have received, on the Closing Date, a certificate, dated the Closing Date and signed by an executive officer of the Company, to the foregoing effect. Such certificate shall also provide that the representations and warranties of the Company contained herein are true and correct as of the Closing Date. The officer making such certificate may rely upon the best of his knowledge as to proceedings pending or threatened. (b) The Manager shall have received on the Closing Date an opinion of Richard J. Agnich, Esq., Senior Vice President, Secretary and General Counsel of the Company, dated the Closing Date, to the effect that: (i) the Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Delaware and has full corporate power and authority to own its properties and conduct its business as presently conducted; (ii) the Company is duly qualified to transact business and is in good standing in each other state of the United States, wherein it owns or leases material property or conducts material business, which requires such qualification, except to the extent that the 3

failure to be so qualified or be in good standing would not have a material adverse effect on the Company; (iii) the Indenture has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company and the Senior Indenture or Subordinated Indenture, as appropriate, is qualified under the Trust Indenture Act of 1939; (iv) the Offered Debt Securities have been duly authorized and, when executed and authenticated in accordance with the Indenture and when delivered to and paid for by the Underwriters or by institutional investors, if any, pursuant to Delayed Delivery Contracts, will be valid and binding obligations of the Company and will be entitled to the benefits of the Indenture; (v) this Agreement has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company, except as rights to indemnity hereunder may be limited under applicable law; (vi) the Offered Debt Securities conform in all material respects to the description thereof contained in the Prospectus, as then amended or supplemented, if applicable, under the caption "Description of Debt Securities"; (vii) the Registration Statement, and any amendments thereto, is effective under the Securities Act of 1933, and, to the best of such counsel's knowledge, no proceedings for a stop order are pending or threatened by the Commission; (viii) the execution, delivery and performance of the Underwriting Agreement, the Offered Debt Securities and the Indenture will not contravene any provision of applicable law or the certificate of incorporation or by-laws of the Company or, to the knowledge of such counsel, any agreement or other instrument binding upon the Company, and no consent, approval or authorization of any governmental body or agency is required for the performance by the Company of its obligations under the Underwriting Agreement, the Offered Debt Securities and the Indenture, except such as are specified and have been obtained and such as may be required by the securities or Blue Sky laws of the various states in connection with the purchase and distribution of the Offered Debt Securities by the Underwriters; 4

(ix) the statements in the Prospectus under the captions "Description of Debt Securities" and "Plan of Distribution", insofar as they constitute summaries of documents or proceedings referred to therein, are accurate summaries in all material respects of such documents and proceedings; (x) after due inquiry, such counsel does not know of any legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject that are required to be described in the Registration Statement or the Prospectus and are not so described or of any contract or other document that is required to be described in the Registration Statement or the Prospectus or to be filed as an exhibit to the Registration Statement that is not described or filed as required; and (xi) such counsel (1) is of the opinion that each document, if any, filed pursuant to the Securities Exchange Act of 1934 (except for financial statements included therein, as to which such counsel need not express any opinion) and incorporated by reference in the Registration Statement and Prospectus complied when so filed as to form in all material respects with such Act and the rules and regulations thereunder, (2) has no knowledge that (except for the financial statements contained therein, as to which such counsel need not express any belief) any part of the Registration Statement (including the documents incorporated by reference therein) filed with the Commission pursuant to the Securities Act of 1933 relating to the Offered Debt Securities, when such part became effective, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (3) is of the opinion that the Registration Statement and Prospectus, as amended or supplemented, if applicable (except for financial statements included therein, as to which such counsel need not express any opinion), comply as to form in all material respects with the Securities Act of 1933 and the rules and regulations thereunder and (4) has no knowledge that (except for the financial statements contained therein, as to which such counsel need not express any belief) the Prospectus, as amended or supplemented, if applicable, contains any untrue statement of a material fact or omits to state a material fact necessary in order to 5

make the statements therein, in the light of the circumstances under which they were made, not misleading. (c) The Manager shall have received on the Closing Date an opinion of Davis Polk & Wardwell, counsel for the Underwriters, dated the Closing Date, to the effect set forth in (iii), (iv), (v), (vii), (ix) (as to "Description of Debt Securities") and (xi) of (b) above, and further to the effect that statements in the Prospectus under the caption "Plan of Distribution", insofar as such statements constitute a summary of the documents referred to therein, are accurate summaries of the material provisions of such documents. It is understood that Richard J. Agnich, Esq. may rely as to all matters relating to the laws of the State of New York upon the opinion of Davis Polk & Wardwell. With respect to the matters set forth in (b)(xi) above, Richard J. Agnich, Esq., and Davis Polk & Wardwell may state that their belief is based upon participation by them in the preparation of the Registration Statement (excluding any documents incorporated by reference therein) and review and discussion of the contents thereof (including any such incorporated documents), but is without independent check or verification, except as specified. (d) The Manager shall have received on the Closing Date a letter dated the Closing Date, in form and substance satisfactory to the Manager, from the Company's independent public accountants, containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement and the Prospectus. (e) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have occurred any downgrading, nor shall any notice have been given of (i) any intended or potential downgrading or (ii) any review or possible change that, in the Manager's opinion, indicates an intended or potential downgrading in the rating accorded any of the Company's securities by any "nationally recognized statistical rating organization", as such term is defined for purposes of Rule 436(g)(2) under the Securities Act of 1933, that, in the Manager's judgment, is material and adverse and that makes it, in the Manager's judgment, impracticable to market the Offered Debt Securities on the terms, in the manner and substantially at the price contemplated in the Prospectus. 6

(f) There shall not have occurred any change, or any event that is reasonably likely to cause a change, in the financial condition of the Company and its subsidiaries, taken as a whole, from that set forth in or contemplated by the Registration Statement and the Prospectus, that, in the Manager's judgment, is material and adverse and that makes it, in the manager's judgment, impracticable to market the Offered Debt Securities on the terms, in the manner and substantially at the price contemplated in the Prospectus. VI. In further consideration of the agreements of the Underwriters contained in this Agreement, the Company covenants as follows: (a) To furnish the Manager, without charge, three copies of the Registration Statement, including exhibits and materials, if any, incorporated by reference therein, and, during the period mentioned in paragraph (c) below, as many copies of the Prospectus, any documents incorporated by reference therein and any supplements and amendments thereto as the Manager may reasonably request. The terms "supplement" and "amendment" or "amend" as used in this Agreement shall include all documents filed by the Company with the Commission subsequent to the date of the Basic Prospectus, pursuant to the Securities Exchange Act of 1934, which are deemed to be incorporated by reference in the Prospectus. (b) Before amending or supplementing the Registration Statement or the Prospectus with respect to the Offered Debt Securities, to furnish the Manager a copy of each such proposed amendment or supplement. (c) If, during such period after the first date of the public offering of the Offered Debt Securities as in the opinion of counsel for the Underwriters the Prospectus is required by law to be delivered, any event shall occur or condition shall exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading, or if it is necessary to amend or supplement the Prospectus to comply with law, forthwith to prepare and furnish, at its own expense, to the Underwriters, either amendments or supplements to the Prospectus so that the statements in the 7

Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law. (d) To qualify the Offered Debt Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Manager shall reasonably request and to pay all expenses (including fees and disbursements of counsel) in connection with such qualification. (e) To make generally available to the Company's security holders as soon as practicable an earning statement covering a twelve month period beginning after the date of the Underwriting Agreement, which shall satisfy the provisions of Section 11(a) of the Securities Act of 1933 and the applicable rules and regulations thereunder; it being intended that the Company will satisfy the foregoing obligations by making available copies of its annual report on Form 10-K and its current reports on Form 10-Q. (f) During the period beginning on the date of the Underwriting Agreement and continuing to and including the Closing Date, not to offer, sell, contract to sell or otherwise dispose of any debt securities of the Company substantially similar to the Offered Debt Securities without the prior written consent of the Manager. VII. The Company represents and warrants to each Underwriter that (i) each document, if any, filed or to be filed pursuant to the Securities Exchange Act of 1934 and incorporated by reference in the Prospectus complied or will comply when so filed in all material respects with such Act and the rules and regulations thereunder, (ii) each part of the Registration Statement (including the documents incorporated by reference therein) filed with the Commission pursuant to the Securities Act of 1933 relating to the Offered Debt Securities, when such part became effective, did not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) each preliminary prospectus, if any, filed pursuant to Rule 424 under the Securities Act of 1933 complied when so filed in all material respects with such Act and the applicable rules and regulations thereunder, (iv) the Registration Statement and the Prospectus comply and, as amended or supplemented, if applicable, will comply in all material respects with the Securities Act of 1933 and the applicable rules and regulations thereunder and 8

(v) the Registration Statement and the Prospectus do not contain and, as amended or supplemented, if applicable, will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that these representations and warranties do not apply to (a) that part of the Registration Statement that constitutes the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of 1939 of the Trustee under the Indenture, or (b) statements or omissions in the Registration Statement, any preliminary prospectus or the Prospectus based upon information furnished to the Company in writing by any Underwriter expressly for use therein. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act of 1933 or Section 20 of the Securities Exchange Act of 1934, from and against any and all losses, claims, damages and liabilities (including the reasonable fees and expenses of counsel in connection with any governmental or regulatory investigation or proceeding) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus or the Prospectus (if used within the period set forth in paragraph (c) of Article VI hereof and as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company in writing by any Underwriter expressly for use therein. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the 9

indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Manager in the case of parties indemnified pursuant to the second preceding paragraph and by the Company in the case of parties indemnified pursuant to the first preceding paragraph. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the third sentence of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 10 business days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. If the indemnification provided for in this Article VII under the second or third paragraphs hereof is unavailable in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the 10

other from the offering of the Offered Debt Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other in connection with the offering of the Offered Debt Securities shall be deemed to be in the same proportion as the net proceeds from the offering of such Offered Debt Securities (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters in respect thereof, in each case as set forth in the table on the cover of the Prospectus. The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Article VII were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Article VII, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Debt Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act of 1933) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Article VII are several, in proportion to the respective principal amounts of Offered Debt Securities purchased by each of such Underwriters, and not joint. The indemnity and contribution agreements contained in this Article VII and the representations and warranties of the Company in this Agreement shall 11

remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its directors or officers or any person controlling the Company and (iii) acceptance of and payment for any of the Offered Debt Securities. VIII. This Agreement shall be subject to termination in the Manager's absolute discretion, by notice given to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange or the National Association of Securities Dealers, Inc., (ii) trading of any securities of the Company shall have been suspended on the New York Stock Exchange or in the U.S. over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities or a severe deterioration in U.S. financial markets or any other calamity or crisis that is material and adverse and (b) in the case of any of the events specified in clauses (a) (i) through (iv), such event singly or together with any other such event makes it, in the Manager's judgment, impracticable to market the Offered Debt Securities on the terms, in the manner and substantially at the price contemplated in the Prospectus. Any such termination of this Agreement shall be without liability on the part of any Manager or on the part of the Company except as stated in Article IX. IX. If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase Underwriters' Securities that it or they have agreed to purchase on such date, and the aggregate principal amount of Underwriters' Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Underwriters' Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Offered Debt Securities set forth opposite their respective names in the Underwriting Agreement bears to the aggregate principal amount of Offered Debt Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Manager may specify, to purchase the Underwriters' Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of 12

Underwriters' Securities that any Underwriter has agreed to purchase pursuant to the Underwriting Agreement be increased pursuant to this Article IX by an amount in excess of one-ninth of such principal amount of Underwriters' Securities without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Underwriters' Securities and the aggregate principal amount of Underwriters' Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Underwriters' Securities to be purchased on such date, and arrangements satisfactory to the Underwriters and the Company for the purchase of such Underwriters' Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Underwriters or the Company shall have the right to postpone the Closing Date but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement, with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with the Offered Debt Securities. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 13

Such signatures may be the manual or facsimile signatures of the present or any future such officers. The seal of the Issuer may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Securities. Typographical and other minor errors or defects in any such reproduction of the seal or any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee. In case any officer of the Issuer who shall have signed any of the Securities or Coupons, if any, shall cease to be such officer before the Security or Coupon so signed (or the Security to which the Coupon so signed appertains) shall be authenticated and delivered by the Trustee or disposed of by the Issuer, such Security or Coupon nevertheless may be authenticated and delivered or disposed of as though the person who signed such Security or Coupon had not ceased to be such officer of the Issuer; and any Security or Coupon may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Security or Coupon, shall be the proper officers of the Issuer, although at the date of the execution and delivery of this Indenture any such person was not such an officer.

Only such Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized officers, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. No Coupon shall be entitled to the benefits of this Indenture or shall be valid and obligatory for any purpose until the certificate of authentication 15

on the Security to which such Coupon appertains shall have been duly executed by the Trustee. The execution of such certificate by the Trustee upon any Security executed by the Issuer shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture. SECTION 2.07. Denomination and Date of Securities; Payments of Interest. The Securities of each series shall be issuable as Registered Securities or Unregistered Securities in denominations established as contemplated by Section 2.03 or, with respect to the Registered Securities of any series, if not so established, in denominations of $1,000 and any integral multiple thereof. If denominations of Unregistered Securities of any series are not so established, such Securities shall be issuable in denominations of $1,000 and $5,000. The Securities of each series shall be numbered, lettered or otherwise distinguished in such manner or in accordance with such plan as the officers of the Issuer executing the same may determine with the approval of the Trustee, as evidenced by the execution and authentication thereof. Unless otherwise indicated in a Board Resolution or supplemental indenture for a particular series, interest will be calculated on the basis of a 360-day year of twelve 30-day months. Each Registered Security shall be dated the date of its authentication. Each Unregistered Security shall be dated as provided in the resolution or resolutions of the Board of Directors of the Issuer referred to in Section 2.03. The Securities of each series shall bear interest, if any, from the date, and such interest shall be payable on the dates, established as contemplated by Section 2.03. The Person in whose name any Registered Security of any series is registered at the close of business on any record date applicable to a particular series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on such interest payment date notwithstanding any transfer, exchange or conversion of such Registered Security subsequent to the record date and prior to such interest payment date (subject, in the case of conversion of such Security during such period, to Section 14.02), except if and to the extent the Issuer shall default in the payment of the interest due on such interest payment date for such series, in which case such defaulted interest shall be paid to the Persons in whose names Outstanding Registered Securities for such series are registered at the close of business on a subsequent record date (which shall be not less than five Business Days prior to the date of payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer to the Holders of Registered Securities not less than 15 days preceding such subsequent record date. The term "record date" as used with respect to any interest payment date (except a date for payment of defaulted interest) for the Securities of any series shall mean the date specified as such in the terms of the 16

Registered Securities of such series established as contemplated by Section 2.03, or, if no such date is so established, if such interest payment date is the first day of a calendar month, the 15th day of the next preceding calendar month or, if such interest payment date is the 15th day of a calendar month, the first day of such calendar month, whether or not such record date is a Business Day. SECTION 2.08. Registration, Transfer and Exchange. The Issuer will keep at each office or agency to be maintained for the purpose as provided in Section 3.02 for each series of Securities a register or registers in which, subject to such reasonable regulations as it may prescribe, it will provide for the registration of Securities of such series and the registration of transfer of Registered Securities of such series. Such register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. At all reasonable times such register or registers shall be open for inspection by the Trustee. Upon due presentation for registration of transfer of any Registered Security of any series at any such office or agency to be maintained for the purpose as provided in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Registered Security or Registered Securities of the same series, maturity date, interest rate and original issue date in authorized denominations for a like aggregate principal amount. Unregistered Securities (except for any temporary Unregistered Securities) and Coupons (except for Coupons attached to any temporary Unregistered Securities) shall be transferable by delivery. At the option of the Holder thereof, Registered Securities of any series (except a Registered Global Security) may be exchanged for a Registered Security or Registered Securities of such series having authorized denominations and an equal aggregate principal amount, upon surrender of such Registered Securities to be exchanged at the agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.02 and upon payment, if the Issuer shall so require, of the charges hereinafter provided. If the Securities of any series are issued in both registered and unregistered form, except as otherwise specified pursuant to Section 2.03, at the option of the Holder thereof, Unregistered Securities of any series may be exchanged for Registered Securities of such series having authorized denominations and an equal aggregate principal amount, upon surrender of such Unregistered Securities to be exchanged at the agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.02, with, in the case of Unregistered Securities that have Coupons attached, all unmatured Coupons and all matured Coupons in default thereto appertaining, and 17

upon payment, if the Issuer shall so require, of the charges hereinafter provided. At the option of the Holder thereof, if Unregistered Securities of any series, maturity date, interest rate and original issue date are issued in more than one authorized denomination, except as otherwise specified pursuant to Section 2.03, such Unregistered Securities may be exchanged for Unregistered Securities of such series having authorized denominations and an equal aggregate principal amount, upon surrender of such Unregistered Securities to be exchanged at the agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.02 or as specified pursuant to Section 2.03, with, in the case of Unregistered Securities that have Coupons attached, all unmatured Coupons and all matured Coupons in default thereto appertaining, and upon payment, if the Issuer shall so require, of the charges hereinafter provided. Unless otherwise specified pursuant to Section 2.03, Registered Securities of any series may not be exchanged for Unregistered Securities of such series. Whenever any Securities are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities and Coupons surrendered upon any exchange or transfer provided for in this Indenture shall be promptly cancelled and disposed of by the Trustee and the Trustee will deliver a certificate of disposition thereof to the Issuer. All Registered Securities presented for registration of transfer, exchange, redemption or payment shall (if so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the Holder or his or her attorney duly authorized in writing. The Issuer may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in connection with any exchange or registration of transfer of Securities. No service charge shall be made for any such transaction. The Issuer shall not be required to exchange or register a transfer of (a) any Securities of any series for a period of 15 days next preceding the first mailing of notice of redemption of Securities of such series to be redeemed or (b) any Securities selected, called or being called for redemption, in whole or in part, except, in the case of any Security to be redeemed in part, the portion thereof not so to be redeemed. Notwithstanding any other provision of this Section 2.08, unless and until it is exchanged in whole or in part for Securities in definitive registered form, a Registered Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series 18

to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. If at any time the Depositary for the Registered Securities of a series notifies the Issuer that it is unwilling or unable to continue as Depositary for the Registered Securities of such series or if at any time the Depositary for the Registered Securities of a series shall no longer be eligible under Section 2.04, the Issuer shall appoint a successor Depositary with respect to the Registered Securities of such series. If a successor Depositary for the Registered Securities of such series is not appointed by the Issuer within 90 days after the Issuer receives such notice or becomes aware of such ineligibility, the Issuer's election pursuant to Section 2.03 that the Registered Securities of such series be represented by a Registered Global Security shall no longer be effective and the Issuer will execute, and the Trustee, upon receipt of an Officer's Certificate for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive registered form without Coupons, in any authorized denominations, in an aggregate principal amount equal to the principal amount of the Registered Global Security or Securities representing the Registered Securities of such series, in exchange for such Registered Global Security or Securities. The Issuer may at any time and in its sole discretion determine that the Registered Securities of any series issued in the form of one or more Registered Global Securities shall no longer be represented by a Registered Global Security or Securities. In such event the Issuer will execute, and the Trustee, upon receipt of an Officer's Certificate for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive registered form without Coupons, in any authorized denominations, in an aggregate principal amount equal to the principal amount of the Registered Global Security or Securities representing such series, in exchange for such Registered Global Security or Securities. If specified by the Issuer pursuant to Section 2.03 with respect to Securities represented by a Registered Global Security, the Depositary for such Registered Global Security may surrender such Registered Global Security in exchange in whole or in part for Securities of the same series in definitive registered form on such terms as are acceptable to the Issuer and such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and deliver, without service charge, 19

(a) to the Person specified by such Depositary a new Registered Security or Securities of the same series, of any authorized denominations as requested by such Person, in an aggregate principal amount equal to and in exchange for such Person's beneficial interest in the Registered Global Security; and (b) to such Depositary a new Registered Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Registered Global Security and the aggregate principal amount of Registered Securities authenticated and delivered pursuant to clause (a) above. Upon the exchange of a Registered Global Security for Securities in definitive registered form without Coupons, in authorized denominations, such Registered Global Security shall be cancelled by the Trustee. Securities in definitive registered form without Coupons issued in exchange for a Registered Global Security pursuant to this Section 2.08 shall be registered in such names and in such authorized denominations as the Depositary for such Registered Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to or as directed by the Persons in whose names such Securities are so registered. All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. Notwithstanding anything herein or in the terms of any series of Securities to the contrary, neither the Issuer nor the Trustee (which shall rely on an Officers' Certificate and an Opinion of Counsel) shall be required to exchange any Unregistered Security for a Registered Security if such exchange would result in adverse Federal income tax consequences to the Issuer (such as, for example, the inability of the Issuer to deduct from its income, as computed for Federal income tax purposes, the interest payable on the Unregistered Securities) under then applicable United States Federal income tax laws. SECTION 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security or any Coupon appertaining to any Security shall become mutilated, defaced or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request of any officer of the Issuer, the Trustee shall authenticate and deliver a new Security of the same series, maturity date, interest rate and original issue date, bearing a number or other distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the mutilated or defaced Security, or in lieu of and substitution for the Security so destroyed, lost or stolen with Coupons corresponding to the 20

Coupons appertaining to the Securities so mutilated, defaced, destroyed, lost or stolen, or in exchange or substitution for the Security to which such mutilated, defaced, destroyed, lost or stolen Coupon appertained, with Coupons appertaining thereto corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen. In every case the applicant for a substitute Security or Coupon shall furnish to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as may be required by them to indemnify and defend and to save each of them harmless and, in every case of destruction, loss or theft, evidence to their satisfaction of the destruction, loss or theft of such Security or Coupon and of the ownership thereof and in the case of mutilation or defacement shall surrender the Security and related Coupons to the Trustee. Upon the issuance of any substitute Security or Coupon, the Issuer may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. In case any Security or Coupon which has matured or is about to mature or has been called for redemption in full, or is being surrendered for conversion in full, shall become mutilated or defaced or be destroyed, lost or stolen, the Issuer may, instead of issuing a substitute Security (with the Holder's consent, in the case of convertible Securities), pay or authorize the payment of the same or the relevant Coupon or convert, or authorize conversion of the same (without surrender thereof except in the case of a mutilated or defaced Security or Coupon), if the applicant for such payment shall furnish to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security or Coupon and of the ownership thereof. Every substitute Security or Coupon of any series issued pursuant to the provisions of this Section by virtue of the fact that any such Security or Coupon is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Security or Coupon shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other Securities or Coupons of such series duly authenticated and delivered hereunder. All Securities and Coupons shall be held and owned upon the express condition that, to the extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment or conversion of mutilated, defaced or destroyed, lost or stolen Securities and Coupons and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the 21

replacement or payment of negotiable instruments or other securities without their surrender. SECTION 2.10. Cancellation of Securities; Destruction Thereof. All Securities and Coupons surrendered for exchange for Securities of the same series or for payment, redemption, registration of transfer, conversion or for credit against any payment in respect of a sinking or analogous fund, if surrendered to the Issuer or any agent of the Issuer or the Trustee, shall be delivered to the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no Securities or Coupons shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of cancelled Securities and Coupons held by it and deliver a certificate of disposition to the Issuer. If the Issuer shall acquire any of the Securities or Coupons, such acquisition shall not operate as a redemption or satisfaction of the Debt represented by such Securities or Coupons unless and until the same are delivered to the Trustee for cancellation. SECTION 2.11. Temporary Securities. Pending the preparation of definitive Securities for any series, the Issuer may execute and the Trustee shall authenticate and deliver temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable as Registered Securities without Coupons, or as Unregistered Securities with or without Coupons attached thereto, of any authorized denomination, and substantially in the form of the definitive Securities of such series but with such omissions, insertions and variations as may be appropriate for temporary Registered Securities, all as may be determined by the Issuer with the concurrence of the Trustee as evidenced by the execution and authentication thereof. Temporary Securities may contain such reference to any provisions of this Indenture as may be appropriate. Every temporary Security shall be executed by the Issuer and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay the Issuer shall execute and shall furnish definitive Securities of such series and thereupon temporary Registered Securities of such series may be surrendered in exchange therefor without charge at each office or agency to be maintained by the Issuer for that purpose pursuant to Section 3.02 and, in the case of Unregistered Securities, at any agency maintained by the Issuer for such purpose as specified pursuant to Section 2.03, and the Trustee shall authenticate and deliver in exchange for such temporary Securities of such series an equal aggregate principal amount of definitive Securities of the same series having authorized denominations and, in the case of Unregistered Securities, having attached thereto any appropriate Coupons. Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits under this 22

Indenture as definitive Securities of such series, unless the benefits of the temporary Securities are limited pursuant to Section 2.03. The provisions of this Section are subject to any restrictions or limitations on the issue and delivery of temporary Unregistered Securities of any series that may be established pursuant to Section 2.03 (including any provision that Unregistered Securities of such series initially be issued in the form of a single global Unregistered Security to be delivered to a depositary or agency located outside the United States and the procedures pursuant to which definitive or global Unregistered Securities of such series would be issued in exchange for such temporary global Unregistered Security). ARTICLE 3 COVENANTS OF THE ISSUER SECTION 3.01. Payment of Principal and Interest. The Issuer covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay or cause to be paid the principal of, and interest on, each of the Securities of such series (together with any additional amounts payable pursuant to the terms of such Securities) at the place or places, at the respective times and in the manner provided in such Securities and in the Coupons, if any, appertaining thereto and in this Indenture. The interest on Securities with Coupons attached (together with any additional amounts payable pursuant to the terms of such Securities) shall be payable only upon presentation and surrender of the several Coupons for such interest installments as are evidenced thereby as they severally mature. If any temporary Unregistered Security provides that interest thereon may be paid while such Security is in temporary form, the interest on any such temporary Unregistered Security (together with any additional amounts payable pursuant to the terms of such Security) shall be paid, as to the installments of interest evidenced by Coupons attached thereto, if any, only upon presentation and surrender thereof, and, as to the other installments of interest, if any, only upon presentation of such Securities for notation thereon of the payment of such interest, in each case subject to any restrictions that may be established pursuant to Section 2.03. The interest on Registered Securities (together with any additional amounts payable pursuant to the terms of such Securities) shall be payable only to or upon the written order of the Holders thereof and at the option of the Issuer may be paid by mailing checks for such interest payable to or upon the written order of such Holders at their last addresses as they appear on the registry books of the Issuer. SECTION 3.02. Offices for Payments, Etc. The Issuer will maintain (a) in the Borough of Manhattan, The City of New York, an agency where the 23

Registered Securities of each series may be presented for payment, an agency where the Securities of each series may be presented for exchange and conversion, if applicable, as is provided in this Indenture and, if applicable, pursuant to Section 2.03 and an agency where the Registered Securities of each series may be presented for registration of transfer as in this Indenture provided and (b) such further agencies in such places as may be determined for the Securities of such series pursuant to Section 2.03. The Issuer will maintain one or more agencies in a city or cities located outside the United States (including any city in which such an agency is required to be maintained under the rules of any stock exchange on which the Securities of such series are listed) where the Unregistered Securities, if any, of each series and Coupons, if any, appertaining thereto may be presented for payment. No payment on any Unregistered Security or Coupon will be made upon presentation of such Unregistered Security or Coupon at an agency of the Issuer within the United States nor will any payment be made by transfer to an account in, or by mail to an address in, the United States unless pursuant to applicable United States laws and regulations then in effect such payment can be made without adverse tax consequences to the Issuer. Notwithstanding the foregoing, payments in Dollars of Unregistered Securities of any series and Coupons appertaining thereto which are payable in Dollars may be made at an agency of the Issuer maintained in the Borough of Manhattan, The City of New York, if such payment in Dollars at each agency maintained by the Issuer outside the United States for payment on such Unregistered Securities is illegal or effectively precluded by exchange controls or other similar restrictions. The Issuer will maintain in the Borough of Manhattan, The City of New York, an agency where notices and demands to or upon the Issuer in respect of the Securities of any series, the Coupons appertaining thereto or this Indenture may be served. The Issuer will give to the Trustee written notice of the location of each such agency and of any change of location thereof. In case the Issuer shall fail to maintain any agency required by this Section to be located in the Borough of Manhattan, The City of New York, or shall fail to give such notice of the location or of any change in the location of any of the above agencies, presentations and demands may be made and notices may be served at the Corporate Trust Office of the Trustee. The Issuer may from time to time designate one or more additional agencies where the Securities of a series and any Coupons appertaining thereto may be presented for payment, where the Securities of that series may be presented for exchange or conversion, if applicable, as provided in this Indenture 24

and pursuant to Section 2.03 and where the Registered Securities of that series may be presented for registration of transfer as in this Indenture provided, and the Issuer may from time to time rescind any such designation, as the Issuer may deem desirable or expedient; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain the agencies provided for in this Section. The Issuer will give to the Trustee prompt written notice of any such designation or rescission thereof. SECTION 3.03. Appointment to Fill a Vacancy in Office of Trustee. The Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so that there shall at all times be a Trustee with respect to each series of Securities hereunder. SECTION 3.04. Paying Agents. Whenever the Issuer shall appoint a paying agent other than the Trustee with respect to the Securities of any series, it will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section, (a) that it will hold all sums received by it as such agent for the payment of the principal of or interest on the Securities of such series (whether such sums have been paid to it by the Issuer or by any other obligor on the Securities of such series) in trust for the benefit of the Holders of the Securities of such series, or Coupons appertaining thereto, if any, or of the Trustee, (b) that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Securities of such series) to make any payment of the principal of or interest on the Securities of such series when the same shall be due and payable, and (c) that at any time during the continuance of any such failure, upon the written request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust by such paying agent. The Issuer will, on or prior to each due date of the principal of or interest on the Securities of such series, deposit with the paying agent a sum sufficient to pay such principal or interest so becoming due, and (unless such paying agent is the Trustee) the Issuer will promptly notify the Trustee of any failure to take such action. If the Issuer shall act as its own paying agent with respect to the Securities of any series, it will, on or before each due date of the principal of or interest on the Securities of such series, set aside, segregate and hold in trust for the benefit 25

of the Holders of the Securities of such series or the Coupons appertaining thereto a sum sufficient to pay such principal or interest so becoming due. The Issuer will promptly notify the Trustee of any failure to take such action. Anything in this Section to the contrary notwithstanding, but subject to Section 10.01, the Issuer may at any time, for the purpose of obtaining a satisfaction and discharge with respect to one or more or all series of Securities hereunder, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust for any such series by the Issuer or any paying agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein contained. Anything in this Section to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section is subject to the provisions of Sections 10.03 and 10.04. SECTION 3.05. Written Statement to Trustee. So long as any Securities are Outstanding, the Issuer will deliver to the Trustee on or before July 15 in each year (beginning in 1999) a written statement covering the previous calendar year, signed by two of its officers (which need not comply with Section 11.05), stating that in the course of the performance of their duties as officers of the Issuer they would normally have knowledge of any default by the Issuer in the performance or fulfillment of any covenant, agreement or condition contained in this Indenture, stating whether or not they have knowledge of any such default and, if so, specifying each such default of which the signers have knowledge and the nature thereof. SECTION 3.06. Limitation on Liens. The following provisions shall apply to the Securities of each series unless specifically otherwise provided in a Board Resolution, Officers' Certificate or indenture supplemental hereto as provided pursuant to Section 2.03. (a) The Issuer will not issue or assume, and will not permit any Restricted Subsidiary to issue or assume, any Debt secured by any mortgage, pledge, lien or other encumbrance (mortgages, pledges, liens and other encumbrances being hereinafter called "Mortgage" or "Mortgages") upon any Principal Manufacturing Property, or shares of capital stock or Debt of any Restricted Subsidiary (whether such Principal Manufacturing Property, shares of stock or Debt is now owned or hereafter acquired) without in any such case effectively providing, concurrently with the issuance or assumption of such Debt, that the Securities (together with, if the Issuer shall so determine, any other Debt of the Issuer or such Restricted Subsidiary ranking equally with the Securities and 26

then existing or thereafter created) shall be secured equally and ratably with such Debt; provided, that the foregoing restrictions shall not apply to: (i) Mortgages on any Principal Manufacturing Property hereafter acquired by the Issuer or a Restricted Subsidiary prior to, at the time of, or within 120 days after the latest of the acquisition, completion of construction (including any improvements on an existing property) or commencement of commercial operation of such property, to secure or provide for the payment or financing of all or any part of the purchase price thereof or construction of fixed improvements thereon, or, in addition to assumptions in transactions contemplated by subparagraph (ii) below, the assumption of any Mortgage upon any such property hereafter acquired existing at the time of such acquisition, or the acquisition of any such property subject to any Mortgage without the assumption thereof; provided, that the aggregate principal amount of Debt secured by any such Mortgage so issued, assumed or existing shall not exceed 100% of the cost of such Principal Manufacturing Property to the corporation acquiring the same or of the fair value thereof (as determined by resolution adopted by the Board of Directors) at the time of such acquisition, whichever is less, and provided, further, that in the case of any such acquisition, construction or improvement the Mortgage shall not apply to any property theretofore owned by the Issuer or a Restricted Subsidiary, other than, in the case of any such construction or improvement, any theretofore unimproved real property on which the property so constructed, or the improvement, is located; (ii) the assumption of any Mortgage on any Principal Manufacturing Property of a corporation which is merged into or consolidated with the Issuer or a Restricted Subsidiary or substantially all the assets of which are acquired by the Issuer or a Restricted Subsidiary; (iii) Mortgages on any Principal Manufacturing Property of the Issuer or a Restricted Subsidiary in favor of the United States of America or any State thereof, or any department, agency or instrumentality or political subdivision of the United States of America or any State thereof, or in favor of any other country, or any political subdivision thereof, to secure partial, progress, advance or other payments pursuant to any contract or statute or to secure any Debt incurred or guaranteed for the purpose of financing all or any part of the cost of acquiring, constructing or improving the property subject to such Mortgages (including Mortgages incurred in connection with pollution control, industrial revenue, Title XI maritime financings or similar financings); 27

(iv) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part, of any Mortgage referred to in the foregoing clauses (i) through (iii); provided, however, that the principal amount of Debt so secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property which secured the Mortgage so extended, renewed or replaced (plus improvements and construction on such property); and (v) Mortgages securing Debt of a Restricted Subsidiary owing to the Issuer or another Restricted Subsidiary. (b) Notwithstanding the provisions of subsection (a) of this Section 3.06, the Issuer or any one or more Subsidiaries may issue or assume Debt secured by a Mortgage in addition to those permitted by subsection (a) of this Section 3.06 and renew, extend or replace such Mortgages; provided, that at the time of such creation, assumption, renewal, extension or replacement, and after giving effect thereto, Exempted Debt does not exceed 5% of Consolidated Net Tangible Assets. SECTION 3.07. Limitation on Sale and Leaseback. The following provisions shall apply to the Securities of each series unless specifically otherwise provided in a Board Resolution, Officers' Certificate or indenture supplemental hereto provided pursuant to Section 2.03. (a) The Issuer will not, nor will it permit any Restricted Subsidiary to, enter into any arrangement with any Person providing for the leasing by the Issuer or any Restricted Subsidiary of any Principal Manufacturing Property, whether such Principal Manufacturing Property is now owned or hereafter acquired, except for temporary leases for a term, including renewals at the option of the lessee, of not more than three years and except for leases between the Issuer and a Restricted Subsidiary or between Restricted Subsidiaries, which property has been or is to be sold or transferred by the Issuer or such Restricted Subsidiary to such Person with the intention of taking back a lease of such property (a "sale and leaseback transaction") unless the proceeds of such sale or transfer shall be at least equal to the fair value of such property as determined by resolution adopted by the Board of Directors and either: (i) the Issuer or such Restricted Subsidiary would be entitled, pursuant to the provisions of Section 3.06, to issue or assume Debt secured by a Mortgage on such property at least equal in amount to the Attributable Debt in respect of such sale and leaseback transaction without equally and ratably securing the Securities; provided, however, that from 28

and after the date on which such sale and leaseback transaction becomes effective the Attributable Debt in respect of such arrangement shall be deemed for all purposes under Section 3.06 and this Section 3.07 to be Debt subject to the provisions of Section 3.06; or (ii) within a period commencing 12 months prior to the consummation of such sale and leaseback transaction and ending 12 months after the consummation of such sale and leaseback transaction, the Issuer or Restricted Subsidiary, as the case may be, has expended, or will expend, for Principal Manufacturing Property an amount equal to (A) the proceeds of such sale and leaseback transaction and the Issuer elects to designate such amount as a credit against such sale and leaseback transaction or (B) a part of the proceeds of such sale and leaseback transaction and the Issuer elects to designate such amount as a credit against such sale and leaseback transaction and treats an amount equal to the remainder of the proceeds as provided in clause (iii) hereof; or (iii) such sale or transfer does not come within the exceptions provided by clause (i) hereof and the Issuer does not make the election permitted by clause (ii) hereof or makes such election only as to part of such proceeds, in either of which events the Issuer will (A) within 120 days after such sale and leaseback transaction, apply an amount equal to the Attributable Debt in respect of such sale and leaseback transaction (less an amount equal to the amount, if any, elected under clause (ii) hereof) to the retirement (other than any mandatory retirement or by way of payment at maturity) of Funded Debt of the Issuer or any Restricted Subsidiary, or (B) consider an amount equal to the Attributable Debt in respect of such sale and leaseback transaction (less an amount equal to the amount, if any, elected under clause (ii) hereof) to be Attributable Debt for purposes of the calculation of Exempted Debt; provided, that, after giving effect thereto, Exempted Debt does not exceed 5% of Consolidated Net Tangible Assets. For the purpose of this Section 3.07 the term "Attributable Debt" shall mean, at the time of determination, the present value (discounted at the interest rate implicit in the lease or, if it is not practicable to determine such rate, then at the Issuer's incremental borrowing rate determined in accordance with generally accepted accounting principles) of the obligation of the lessee for net rental payments during the remaining term of any lease included in the sale and leaseback transaction (including any period for which such lease has been extended or may, at the option of the lessor, be extended). The term "net rental payments" under any lease for any period shall mean the sum of the rental and other payments required to be paid by such lessee thereunder, not including, 29

however, amounts payable by the lessee for maintenance and repairs, insurance, taxes, assessments and similar charges and for contingent rents (such as those based on sales). (b) Notwithstanding the provisions of paragraph (a) of this Section 3.07, the Issuer and any Restricted Subsidiary may enter into sale and leaseback transactions in addition to those permitted by paragraph (a) of this Section 3.07 and without any obligation to make expenditures for Principal Manufacturing Property or to retire any Debt; provided, that at the time of entering into such sale and leaseback transactions and after giving effect thereto, Exempted Debt does not exceed 5% of Consolidated Net Tangible Assets. SECTION 3.08. Luxembourg Publications. In the event of the publication of any notice pursuant to Section 5.11, 6.10(a), 6.11, 8.02, 10.04, 13.02 or 13.06, the party making such publication in the Borough of Manhattan, The City of New York, and London shall also, to the extent that notice is required to be given to Holders of Securities of any series by applicable Luxembourg law or stock exchange regulation, as evidenced by an Officers' Certificate delivered to such party, make a similar publication in Luxembourg.

The Issuer covenants to file with the Trustee, within 15 days after the Issuer is required to file the same with the Commission, copies of the annual reports and of the information, documents, and other reports which the Issuer may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934.

ARTICLE 5 REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT SECTION 5.01. Event of Default Defined; Acceleration of Maturity; Waiver of Default. "Event of Default", with respect to Securities of any series wherever used herein, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) default in the payment of any installment of interest upon any of the Securities of such series as and when the same shall become due and payable, and continuance of such default for a period of 30 days; or (b) default in the payment of all or any part of the principal on any of the Securities of such series as and when the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise; or (c) default in the performance, or breach, of any covenant or warranty of the Issuer in respect of the Securities of such series (other than a covenant or warranty in respect of the Securities of such series a default in the performance or breach of which is elsewhere in this Section specifically dealt with), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of all series affected thereby, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or 31

(d) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Issuer or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or (e) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Issuer or for any substantial part of its property, or make any general assignment for the benefit of creditors; or (f) default by the Issuer in the conversion of any Security in accordance herewith and continuance of such default for a period of 45 days; or (g) any other Event of Default provided in the supplemental indenture or resolution of the Board of Directors under which such series of Securities is issued or in the form of Security for such series. If an Event of Default described in clauses (a), (b), (c), (f) or (g) (if the Event of Default under clause (c) or (g) is with respect to less than all series of Securities then Outstanding) occurs and is continuing, then, and in each and every such case, unless the principal of all of the Securities of such series shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding hereunder (each such series voting as a separate class) by notice in writing to the Issuer (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of such series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) of all Securities of such series and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. If an Event of Default described in clause (c) or (g) (if the Event of Default under clause (c) or (g) is with respect to all series of Securities then Outstanding), (d) or (e) occurs and is continuing, then and in each and every such case, unless the principal of all the Securities shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of all the Securities then Outstanding hereunder (treated as one class), by notice in writing to the Issuer (and to the 32

Trustee if given by Securityholders), may declare the entire principal (or, if any Securities are Original Issue Discount Securities, such portion of the principal as may be specified in the terms thereof) of all the Securities then Outstanding and interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. The foregoing provisions, however, are subject to the condition that if, at any time after the principal (or, if the Securities are Original Issue Discount Securities, such portion of the principal as may be specified in the terms thereof) of the Securities of any series (or of all the Securities, as the case may be) shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of such series (or of all the Securities, as the case may be) and the principal of any and all Securities of such series (or of all the Securities, as the case may be) which shall have become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series, (or at the respective rates of interest or Yields to Maturity of all the Securities, as the case may be) to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee except as a result of negligence or bad faith, and if any and all Events of Default under the Indenture, other than the non-payment of the principal of Securities which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided herein--then and in every such case the Holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, (or of all the Securities, as the case may be, voting as a single class) then Outstanding, by written notice to the Issuer and to the Trustee, may waive all defaults with respect to such series (or with respect to all the Securities, as the case may be) and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon. For all purposes under this Indenture, if a portion of the principal of any Original Issue Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and 33

payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Securities. SECTION 5.02. Collection of Debt by Trustee; Trustee May Prove Debt. The Issuer covenants that (a) in case default shall be made in the payment of any installment of interest on any of the Securities of any series when such interest shall have become due and payable, and such default shall have continued for a period of 30 days or (b) in case default shall be made in the payment of all or any part of the principal of any of the Securities of any series when the same shall have become due and payable, whether upon maturity of the Securities of such series or upon any redemption or by declaration or otherwise--then, upon demand of the Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series the whole amount that then shall have become due and payable on all Securities of such series, and such Coupons, for principal or interest, as the case may be (with interest to the date of such payment upon the overdue principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series); and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor trustee, their respective agents, attorneys and counsel, and any expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor trustee except as a result of its negligence or bad faith. In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Issuer or other obligor upon such Securities and collect in the manner provided by law out of the property of the Issuer or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to be payable. In case there shall be pending proceedings relative to the Issuer or any other obligor upon the Securities under Title 11 of the United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer or its property or such other obligor or its property, or in case of any 34

other comparable judicial proceedings relative to the Issuer or other obligor upon the Securities of any series, or to the creditors or property of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise: (i) to file and prove a claim or claims for the whole amount of principal and interest (or, if the Securities of any series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the Securities of any series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and each predecessor trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor trustee, except as a result of negligence or bad faith) and of the Securityholders allowed in any judicial proceedings relative to the Issuer or other obligor upon the Securities of any series, or to the creditors or property of the Issuer or such other obligor, (ii) unless prohibited by applicable law and regulations, to vote on behalf of the Holders of the Securities of any series in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or person performing similar functions in comparable proceedings, and (iii) to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Securityholders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the Securityholders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Securityholders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor trustee except as a result of its negligence or bad faith and all other amounts due to the Trustee or any predecessor trustee pursuant to Section 6.06. 35

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of any series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person. All rights of action and of asserting claims under this Indenture, or under any of the Securities of any series or Coupons appertaining to such Securities, may be enforced by the Trustee without the possession of any of the Securities of such series or Coupons appertaining to such Securities or the production thereof on any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders of the Securities or Coupons appertaining to such Securities in respect of which such action was taken. In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Securities or Coupons appertaining to such Securities in respect to which such action was taken, and it shall not be necessary to make any Holders of such Securities or Coupons appertaining to such Securities parties to any such proceedings. SECTION 5.03. Application of Proceeds. Any moneys collected by the Trustee pursuant to this Article in respect of any series shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal or interest, upon presentation of the several Securities and Coupons appertaining to such Securities in respect of which monies have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange for the presented Securities of like series if only partially paid, or upon surrender thereof if fully paid: FIRST: To the payment of all amounts due to the Trustee or any predecessor trustee pursuant to Section 6.06; 36

SECOND: In case the principal of the Securities of such series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference; THIRD: In case the principal of the Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and interest, with interest upon the overdue principal, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal and interest or Yield to Maturity, without preference or priority of principal over interest or Yield to Maturity, or of interest or Yield to Maturity over principal, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such principal and accrued and unpaid interest or Yield to Maturity; and FOURTH: To the payment of the remainder, if any, to the Issuer or any other Person lawfully entitled thereto. SECTION 5.04. Suits for Enforcement. In case an Event of Default has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. SECTION 5.05. Restoration of Rights on Abandonment of Proceedings. In case the Trustee shall have proceeded to enforce any right under this Indenture 37

and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and in every such case the Issuer and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the Trustee and the Securityholders shall continue as though no such proceedings had been taken. SECTION 5.06. Limitations on Suits by Securityholders. No Holder of any Security of any series or of any Coupon appertaining thereto shall have any right by virtue or by availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 5.09; it being understood and intended, and being expressly covenanted by the taker and Holder of every Security or Coupon with every other taker and Holder and the Trustee, that no one or more Holders of Securities of any series or Coupons appertaining to such Securities shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other such Holder of Securities or Coupons appertaining to such Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities of the applicable series and Coupons appertaining to such Securities. For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. SECTION 5.07. Unconditional Right of Securityholders to Institute Certain Suits. Notwithstanding any other provision in this Indenture and any provision of any Security, the right of any Holder of any Security or Coupon to receive payment of the principal of and interest on such Security or Coupon on or after the respective due dates expressed in such Security or Coupon, or to convert such Security in accordance with Article 14, or to institute suit for the enforcement of 38

any such payment on or after such respective dates, or for the enforcement of such conversion right, shall not be impaired or affected without the consent of such Holder. SECTION 5.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as provided in Section 5.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or Coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. No delay or omission of the Trustee or of any Holder of Securities or Coupons to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 5.06, every power and remedy given by this Indenture or by law to the Trustee or to the Holders of Securities or Coupons may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders of Securities or Coupons. SECTION 5.09. Control by Holders of Securities. The Holders of a majority in aggregate principal amount of the Securities of each series affected (with each series voting as a separate class) at the time Outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Securities of such series by this Indenture; provided, that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture and provided, further, that (subject to the provisions of Section 6.01) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee, or a trust committee of directors or Responsible Officers of the Trustee shall determine that the action or proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forebearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities of all series so affected not joining in the giving of said direction, it being understood that (subject to Section 6.01) the Trustee shall have no duty to ascertain whether or not such actions or forebearances are unduly prejudicial to such Holders. 39

Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders. SECTION 5.10. Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Securities of any series as provided in Section 5.01, the Holders of a majority in aggregate principal amount of the Securities of such series at the time Outstanding may on behalf of the Holders of all the Securities of such series waive any past default or Event of Default described in clause (c) or (g) of Section 5.01 (or, in the case of an event specified in clause (c) or (g) of Section 5.01 which relates to less than all series of Securities then Outstanding, the Holders of a majority in aggregate principal amount of the Securities then Outstanding affected thereby (each series voting as a separate class) may waive any such default or Event of Default, or, in the case of an event specified in clause (c) or (g) (if the Event of Default under clause (c) or (g) relates to all series of Securities then Outstanding), (d) or (e) of Section 5.01 the Holders of Securities of a majority in principal amount of all the Securities then Outstanding (voting as one class) may waive any such default or Event of Default), and its consequences except a default in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each Security affected. In the case of any such waiver, the Issuer, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. Upon any such waiver, such default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. SECTION 5.11. Trustee to Give Notice of Default, but May Withhold in Certain Circumstances. The Trustee shall, within 90 days after the occurrence of a default with respect to the Securities of any series, give notice of all defaults with respect to that series known to the Trustee (a) if any Unregistered Securities of that series are then Outstanding, to the Holders thereof, by publication at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an Authorized Newspaper in London (and, if required by Section 3.08, at least once in an Authorized Newspaper in Luxembourg) and (b) to all Holders of Securities of such series in the manner and to the extent provided in Section 4.03, unless in each case such defaults shall have been cured before the mailing or publication of such notice (the term "defaults" for the purpose of this Section being hereby defined to mean any event or condition 40

which is, or with notice or lapse of time or both would become, an Event of Default); provided, that, except in the case of default in the payment of the principal of or interest on any of the Securities of such series, or in the payment of any sinking fund installment on such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders of such series. SECTION 5.12. Right of Court to Require Filing of Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Security or Coupon by his or her acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder or group of Securityholders of any series holding in the aggregate more than 10% in aggregate principal amount of the Securities of such series, or, in the case of any suit relating to or arising under clause (c) or (g) of Section 5.01 (if the suit relates to Securities of more than one but less than all series), 10% in aggregate principal amount of Securities then Outstanding and affected thereby, or in the case of any suit relating to or arising under clause (c) or (g) (if the suit under clause (c) or (g) relates to all the Securities then Outstanding), (d) or (e) of Section 5.01, 10% in aggregate principal amount of all Securities then Outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of or interest on any Security on or after the due date expressed in such Security or any date fixed for redemption or for the enforcement of a right to convert any Security in accordance with Article 14. ARTICLE 6 CONCERNING THE TRUSTEE SECTION 6.01. Duties and Responsibilities of the Trustee; During Default; Prior to Default. With respect to the Holders of any series of Securities issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a particular series and after the curing or waiving of all 41

Events of Default which may have occurred with respect to such series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a series has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct, except that (a) prior to the occurrence of an Event of Default with respect to the Securities of any series and after the curing or waiving of all such Events of Default with respect to such series which may have occurred: (i) the duties and obligations of the Trustee with respect to the Securities of any series shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such statements, certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 5.09 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. 42

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there shall be reasonable ground for believing that the repayment of such funds or adequate indemnity against such liability is not reasonably assured to it. The provisions of this Section 6.01 are in furtherance of and subject to Sections 315 and 316 of the Trust Indenture Act of 1939. SECTION 6.02. Certain Rights of the Trustee. In furtherance of and subject to the Trust Indenture Act of 1939 and subject to Section 6.01: (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, Officers' Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; (b) any request, direction, order or demand of the Issuer mentioned herein shall be sufficiently evidenced by an Officers' Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the secretary or an assistant secretary of the Issuer; (c) the Trustee may consult with counsel and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request, order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred therein or thereby; (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture; 43

(f) prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Securities of all series affected then Outstanding; provided, that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such investigation shall be paid by the Issuer or, if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer upon demand; and (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder. SECTION 6.03. Trustee Not Responsible for Recitals, Disposition of Securities or Application of Proceeds Thereof. The recitals contained herein and in the Securities, except the Trustee's certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Securities or Coupons. The Trustee shall not be accountable for the use or application by the Issuer of any of the Securities or of the proceeds thereof. SECTION 6.04. Trustee and Agents May Hold Securities or Coupons; Collections, Etc. The Trustee or any agent of the Issuer or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities or Coupons with the same rights it would have if it were not the Trustee or such agent and may otherwise deal with the Issuer and receive, collect, hold and retain collections from the Issuer with the same rights it would have if it were not the Trustee or such agent. SECTION 6.05. Moneys Held by Trustee. Subject to the provisions of Section 10.04 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent 44

required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or the Trustee shall be under any liability for interest on any moneys received by it hereunder. SECTION 6.06. Compensation and Indemnification of Trustee and its Prior Claim. The Issuer covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Issuer covenants and agrees to pay or reimburse the Trustee and each predecessor trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Issuer also covenants to indemnify the Trustee and each predecessor trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in the premises. The obligations of the Issuer under this Section to compensate and indemnify the Trustee and each predecessor trustee and to pay or reimburse the Trustee and each predecessor trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such additional indebtedness shall be a senior claim to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities or Coupons, and the Securities are hereby subordinated to such senior claim. SECTION 6.07. Right of Trustee to Rely on Officers' Certificate, Etc. Subject to Sections 6.01 and 6.02, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers' Certificate delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 45

SECTION 6.08. Indentures Creating Potential Conflicting Interests for the Trustee. No indentures are hereby specifically described for the purposes of Section 310(b)(1) of the Trust Indenture Act of 1939. SECTION 6.09. Persons Eligible for Appointment as Trustee. The Trustee for each series of Securities hereunder shall at all times be a corporation having a combined capital and surplus of at least $50,000,000 and shall be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of a Federal, State or District of Columbia supervising or examining authority, then, for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. SECTION 6.10. Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one or more or all series of Securities by giving written notice of resignation to the Issuer and (i) if any Unregistered Securities of a series affected are then Outstanding, by giving notice of such resignation to the Holders thereof, by publication at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an Authorized Newspaper in London (and, if required by Section 3.08, at least once in an Authorized Newspaper in Luxembourg), (ii) if any Unregistered Securities of a series affected are then Outstanding, by mailing notice of such resignation to the Holders thereof who have filed their names and addresses with the Trustee pursuant to Section 4.01 at such addresses as were so furnished to the Trustee and (iii) by mailing notice of such resignation to the Holders of then Outstanding Registered Securities of each series affected at their addresses as they shall appear on the registry books. Upon receiving such notice of resignation, the Issuer shall promptly appoint a successor trustee or trustees with respect to the applicable series by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed with respect to any series and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Securityholder who has been a bona fide Holder of a Security or Securities of the applicable series for at least six months may, subject to the provisions of Section 5.12, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 46

(b) In case at any time any of the following shall occur: (i) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act of 1939 with respect to any series of Securities after written request therefor by the Issuer or by any Securityholder who has been a bona fide Holder of a Security or Securities of such series for at least six months; or (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939 and shall fail to resign after written request therefor by the Issuer or by any Securityholder; or (iii) the Trustee shall become incapable of acting with respect to any series of Securities, or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; then, in any such case, the Issuer may remove the Trustee with respect to the applicable series of Securities and appoint a successor trustee for such series by written instrument, in duplicate, executed by order of the Board of Directors of the Issuer, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to Section 315(e) of the Trust Indenture Act of 1939, any Securityholder who has been a bona fide Holder of a Security or Securities of such series for at least six months may on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. (c) The Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding may at any time remove the Trustee with respect to Securities of such series and appoint a successor trustee with respect to the Securities of such series by delivering to the Trustee so removed, to the successor trustee so appointed and to the Issuer the evidence provided for in Section 7.01 of the action in that regard taken by the Securityholders. (d) Any resignation or removal of the Trustee with respect to any series and any appointment of a successor trustee with respect to such series pursuant to 47

any of the provisions of this Section 6.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 6.11. SECTION 6.11. Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 6.10 shall execute and deliver to the Issuer and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee with respect to all or any applicable series shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations with respect to such series of its predecessor hereunder, with like effect as if originally named as trustee for such series hereunder; but, nevertheless, on the written request of the Issuer or of the successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 10.04, pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any such successor trustee, the Issuer shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a prior claim upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 6.06. If a successor trustee is appointed with respect to the Securities of one or more (but not all) series, the Issuer, the predecessor trustee and each successor trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor trustee with respect to the Securities of any series as to which the predecessor trustee is not retiring shall continue to be vested in the predecessor trustee, and shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such trustees co-trustees of the same trust and that each such trustee shall be trustee of a trust or trusts under separate indentures. No successor trustee with respect to any series of Securities shall accept appointment as provided in this Section 6.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 310(b) of the Trust Indenture Act of 1939 and eligible under the provisions of Section 310(a) of the Trust Indenture Act of 1939. 48

Upon acceptance of appointment by any successor trustee as provided in this Section 6.11, the Issuer shall mail notice thereof (a) if any Unregistered Securities of a series affected are then Outstanding, to the Holders thereof, by publication of such notice at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an Authorized Newspaper in London (and, if required by Section 3.08, at least once in an Authorized Newspaper in Luxembourg), (b) if any Unregistered Securities of a series affected are then Outstanding, to the Holders thereof who have filed their names and addresses with the Trustee pursuant to Section 4.01, by mailing such notice to such Holders at such addresses as were so furnished to the Trustee (and the Trustee shall make such information available to the Issuer for such purpose) and (c) to the Holders of Registered Securities of each series affected, by mailing such notice to such Holders at their addresses as they shall appear on the registry books. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 6.10. If the Issuer fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be given at the expense of the Issuer. SECTION 6.12. Merger, Conversion, Consolidation, or Succession to Business of Trustee. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided, that such corporation shall be qualified under the provisions of Section 310(b) of the Trust Indenture Act of 1939 and eligible under the provisions of Section 310(a) of the Trust Indenture Act of 1939, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case, at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Securities of any series shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities of any series shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Securities of such series or in this Indenture provided that the certificate of the Trustee shall have; provided, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Securities 49

of any series in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation. ARTICLE 7 CONCERNING THE SECURITYHOLDERS SECTION 7.01. Evidence of Action Taken by Securityholders. Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by a specified percentage in principal amount of the Securityholders of any or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Securityholders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Sections 6.01 and 6.02) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Article. SECTION 7.02. Proof of Execution of Instruments and of Holding of Securities. Subject to Sections 6.01 and 6.02, the execution of any instrument by a Securityholder or his or her agent or proxy may be proved in the following manner: (a) The fact and date of the execution by any Holder of any instrument may be proved by the certificate of any notary public or other officer of any jurisdiction authorized to take acknowledgments of deeds or administer oaths that the person executing such instruments acknowledged to him or her the execution thereof, or by an affidavit of a witness to such execution sworn to before any such notary or other such officer. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute sufficient proof of the authority of the person executing the same. The fact of the holding by any Holder of an Unregistered Security of any series, and the identifying number of such Security and the date of his or her holding the same, may be proved by the production of such Security or by a certificate executed by any trust company, bank, banker or recognized securities dealer wherever situated satisfactory to the Trustee, if such certificate shall be deemed by the Trustee to be satisfactory. Each such certificate shall be dated and shall state that on the date thereof a Security of such series bearing a specified identifying number was deposited with or exhibited to such trust company, bank, banker or recognized securities dealer by the Person named in such certificate. Any such certificate 50

may be issued in respect of one or more Unregistered Securities of one or more series specified therein. The holding by the Person named in any such certificate of any Unregistered Securities of any series specified therein shall be presumed to continue for a period of one year from the date of such certificate unless at the time of any determination of such holding (i) another certificate bearing a later date issued in respect of the same Securities shall be produced, or (ii) the Security of such series specified in such certificate shall be produced by some other Person, or (iii) the Security of such series specified in such certificate shall have ceased to be Outstanding. Subject to Sections 6.01 and 6.02, the fact and date of the execution of any such instrument and the amount and numbers of Securities of any series held by the Person so executing such instrument and the amount and numbers of any Security or Securities for such series may also be proven in accordance with such reasonable rules and regulations as may be prescribed by the Trustee for such series or in any other manner which the Trustee for such series may deem sufficient. (b) In the case of Registered Securities, the ownership of such Securities shall be proved by the Security register or by a certificate of the Security registrar. (c) If the Issuer shall solicit from the Holders of Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other action, the Issuer may, at its option, by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Issuer shall have no obligation to do so. Notice of such record date shall be given to the Trustee as soon as practicable after the time that the record date has been fixed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders of Registered Securities for the purposes of determining whether Holders of Registered Securities of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities shall be computed as of such record date; provided, that no such authorization, agreement or consent by the Holders of Registered Securities on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. SECTION 7.03. Holders to Be Treated as Owners. The Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the Person in whose name any Security shall be registered upon the Security register for such series as the absolute owner of such Security (whether or not such Security shall be 51

overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of, and, subject to the provisions of this Indenture, interest on, such Security and for all other purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be affected by any notice to the contrary. The Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the Holder of any Unregistered Security and the Holder of any Coupon as the absolute owner of such Unregistered Security or Coupon (whether or not such Unregistered Security or Coupon shall be overdue) for the purpose of receiving payment thereof or on account thereof and for all other purposes and neither the Issuer, the Trustee, nor any agent of the Issuer or the Trustee shall be affected by any notice to the contrary. All such payments so made to any such Person, or upon his or her order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Unregistered Security or Coupon. SECTION 7.04. Securities Owned by Issuer Deemed Not Outstanding. In determining whether the Holders of the requisite aggregate principal amount of Outstanding Securities of any or all series have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Issuer or any other obligor on the Securities with respect to which such determination is being made or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Securities which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to such Securities and that the pledgee is not the Issuer or any other obligor upon the Securities or any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers' Certificate listing and identifying all Securities, if any, known by the Issuer to be owned or held by or for the account of any of the above-described Persons; and, subject to Sections 6.01 and 6.02, the Trustee shall be entitled to accept such Officers' Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding for the purpose of any such determination. 52

SECTION 7.05. Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 7.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action, any Holder of a Security the serial number of which is shown by the evidence to be included among the serial numbers of the Securities the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article, revoke such action so far as concerns such Security. Except as aforesaid, any such action taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon any such Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action shall be conclusively binding upon the Issuer, the Trustee and the Holders of all the Securities affected by such action. ARTICLE 8 SUPPLEMENTAL INDENTURES SECTION 8.01. Supplemental Indentures Without Consent of Securityholders. The Issuer, when authorized by a resolution of its Board of Directors, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto in form satisfactory to the Trustee for one or more of the following purposes: (a) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Securities of one or more series any property or assets; (b) to evidence the succession of another corporation to the Issuer, or successive successions, and the assumption by the successor corporation of the covenants, agreements and obligations of the Issuer pursuant to Article 9; (c) to add to the covenants of the Issuer such further covenants, restrictions, conditions or provisions as its Board of Directors and the Trustee shall consider to be for the protection of the Holders of Securities or Coupons, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default permitting the enforcement of all or any of the several remedies provided 53

in this Indenture as herein set forth; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in aggregate principal amount of the Securities of such series to waive such an Event of Default; (d) to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make any other provisions as the Board of Directors may deem necessary or desirable; provided, that no such action shall adversely affect the interests of the Holders of the Securities or Coupons; (e) to establish the form or terms of Securities of any series or of the Coupons appertaining to such Securities as permitted by Sections 2.01 and 2.03 and to provide for adjustment of conversion rights pursuant to Section 14.05; and (f) to evidence and provide for the acceptance of appointment hereunder by a successor trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, pursuant to the requirements of Section 6.11. The Trustee is hereby authorized to join with the Issuer in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. Any supplemental indenture authorized by the provisions of this Section may be executed without the consent of the Holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 8.02. SECTION 8.02. Supplemental Indentures With Consent of Securityholders. With the consent (evidenced as provided in Article 7) of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series affected by such supplemental indenture (voting as one class), the Issuer, when authorized by a resolution of its Board of Directors, and 54

the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each such series or of the Coupons appertaining to such Securities; provided, that no such supplemental indenture shall (a) extend the final maturity of any Security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof, or make the principal thereof (including any amount in respect of original issue discount) or interest thereon payable in any coin or currency other than that provided in the Securities and Coupons or in accordance with the terms thereof, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereof pursuant to Section 5.01 or the amount thereof provable in bankruptcy pursuant to Section 5.02, or alter the provisions of Section 11.11 or 11.12, or impair or affect the right of any Securityholder to institute suit for the payment or conversion thereof, or materially and adversely affect the right to convert the Securities in accordance with Article 14 or, if the Securities provide therefor, any right of repayment at the option of the Securityholder, in each case without the consent of the Holder of each Security so affected; provided, that no consent of any Holder of any Security shall be necessary under this Section 8.02 to permit the Trustee and the Issuer to execute supplemental indentures pursuant to Section 8.01(e) and Section 14.05 of this Indenture, or (b) reduce the aforesaid percentage of Securities of any series, the consent of the Holders of which is required for any such supplemental indenture, without the consent of the Holders of each Security so affected. A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of Holders of Securities of such series, or of Coupons appertaining to such Securities, with respect to such covenant or provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series or of the Coupons appertaining to such Securities. Upon the request of the Issuer, accompanied by a copy of a resolution of the Board of Directors certified by the secretary or an assistant secretary of the Issuer authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 7.01, the Trustee shall join with the Issuer in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee's own rights, duties or immunities 55

under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. It shall not be necessary for the consent of the Securityholders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. Promptly after the execution by the Issuer and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Trustee shall give a notice thereof (a) to the Holders of then Outstanding Registered Securities of each series affected thereby, by mailing a notice thereof by first-class mail to such Holders at their addresses as they shall appear on the Security register, (b) if any Unregistered Securities of a series affected thereby are then Outstanding, to the Holders thereof who have filed their names and addresses with the Trustee pursuant to Section 4.01, by mailing a notice thereof by first-class mail to such Holders at such addresses as were so furnished to the Trustee and (c) if any Unregistered Securities of a series affected thereby are then Outstanding, to all Holders thereof, by publication of a notice thereof at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an Authorized Newspaper in London (and, if required by Section 3.08, at least once in an Authorized Newspaper in Luxembourg), and in each case such notice shall set forth in general terms the substance of such supplemental indenture. Any failure of the Trustee to mail or publish such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. SECTION 8.03. Effect of Supplemental Indenture. Upon the execution of any supplemental indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Issuer and the Holders of Securities of each series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. SECTION 8.04. Documents to Be Given to Trustee. The Trustee, subject to the provisions of Sections 6.11 and 6.02, may receive an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article 8 complies with the applicable provisions of this Indenture. 56

SECTION 8.05. Notation on Securities in Respect of Supplemental Indentures. Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article may bear a notation in form approved by the Trustee for such series as to any matter provided for by such supplemental indenture or as to any action taken by Securityholders. If the Issuer or the Trustee shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding. ARTICLE 9 CONSOLIDATION, MERGER, SALE OR CONVEYANCE SECTION 9.01. Issuer May Consolidate, Etc., on Certain Terms. The Issuer covenants that it will not merge or consolidate with any other corporation or sell or convey (including by way of lease) all or substantially all of its assets to any Person, unless (a) either the Issuer shall be the continuing corporation, or the successor corporation or the Person which acquires by sale or conveyance substantially all the assets of the Issuer (if other than the Issuer) shall expressly assume the due and punctual payment of the principal of and interest on all the Securities and Coupons, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or observed by the Issuer, including, without limitation, the conversion rights, if any, provided for in accordance with Article 14, by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such corporation or entity, and shall be a corporation or entity organized under the laws of the United States of America or any State thereof or a corporation or entity not organized under such laws which shall agree, in form satisfactory to the Trustee, (i) to subject itself to the jurisdiction of the United States district court for the Southern District of New York, and (ii) to indemnify and hold harmless the holders of all Securities or Coupons against (A) any tax, assessment or governmental charge imposed on such holders by a jurisdiction other than the United States or any political subdivision or taxing authority thereof or therein with respect to, and withheld on the making of, any payment of principal of or interest on such Securities or Coupons and which would not have been so imposed and withheld had such consolidation, merger, sale or conveyance not been made and (B) any tax, assessment or governmental charge imposed on or relating to, and any costs or expenses involved in, such consolidation, merger, sale or conveyance, and (b) the Issuer or such successor corporation or entity, as 57

the case may be, shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition. SECTION 9.02. Successor Issuer Substituted. In case of any such consolidation, merger, sale or conveyance, and following such an assumption by the successor corporation or entity, such successor corporation or entity shall succeed to and be substituted for the Issuer with the same effect as if it had been named herein. Such successor corporation or entity may cause to be signed, and may issue either in its own name or in the name of the Issuer prior to such succession any or all of the Securities issuable hereunder, together with any Coupons appertaining thereto, which theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such successor corporation or entity instead of the Issuer and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities, together with any Coupons appertaining thereto, which previously shall have been signed and delivered by the officers of the Issuer to the Trustee for authentication, and any Securities, together with any Coupons appertaining thereto, which such successor corporation or entity thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Securities so issued, together with any Coupons appertaining thereto, shall in all respects have the same legal rank and benefit under this Indenture as the Securities and Coupons theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities and Coupons had been issued at the date of the execution hereof. In case of any such consolidation, merger, sale, lease or conveyance, such changes in phraseology and form (but not in substance) may be made in the Securities and Coupons thereafter to be issued as may be appropriate. In the event of any such sale or conveyance (other than a conveyance by way of lease), the Issuer or any successor corporation or entity which shall theretofore have become such in the manner described in this Article shall be discharged from all obligations and covenants under this Indenture and the Securities and may be liquidated and dissolved. SECTION 9.03. Opinion of Counsel and Officers' Certificate to Trustee. The Trustee, subject to the provisions of Sections 6.11 and 6.02, may receive an Opinion of Counsel and an Officers' Certificate, prepared in accordance with Section 11.05, as conclusive evidence that any such consolidation, merger, sale, lease or conveyance, and any such assumption, and any such liquidation or dissolution, complies with the applicable provisions of this Indenture. 58

(D) the Issuer has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the defeasance contemplated by this provision have been complied with, and the Opinion of Counsel shall also state that such deposit does not violate applicable law. SECTION 10.02. Application by Trustee of Funds Deposited for Payment of Securities. Subject to Section 10.04, all moneys deposited with the Trustee (or other trustee) pursuant to Section 10.01 shall be held in trust and applied by it to the payment, either directly or through any paying agent (including the Issuer acting as its own paying agent), to the Holders of the particular Securities of such series and of Coupons appertaining thereto for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest; but such money need not be segregated from other funds except to the extent required by law. SECTION 10.03. Repayment of Moneys Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture with respect to Securities of any series, all moneys then held by any paying agent under the provisions of this Indenture with respect to such series of Securities shall, upon demand of the Issuer, be repaid to it or paid to the Trustee and thereupon such paying agent shall be released from all further liability with respect to such moneys. SECTION 10.04. Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any moneys deposited with or paid to the Trustee or any paying agent for the payment of the principal of or interest on any Security of any series or Coupons appertaining thereto and not applied but remaining unclaimed for two years after the date upon which such principal or interest shall have become due and payable, shall, upon the written request of the Issuer and unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Issuer by the Trustee for such series or such paying agent, and the Holder of the Securities of such series and of any Coupons appertaining thereto shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property laws, thereafter look only to the Issuer for any payment which such Holder may be entitled to collect, and all liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease; provided, however, that the Trustee or such paying agent, before being required to make any such repayment with respect to moneys deposited with it for any payment (a) in respect of Registered Securities of any series, shall at the expense of the Issuer, mail by first-class mail to Holders of such Securities at their addresses as they shall appear on the 62

Security register, and (b) in respect of Unregistered Securities of any series, shall at the expense of the Issuer cause to be published once, in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and once in an Authorized Newspaper in London (and if required by Section 3.08, once in an Authorized Newspaper in Luxembourg), notice, that such moneys remain and that, after a date specified therein, which shall not be less than 30 days from the date of such mailing or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. SECTION 10.05. Indemnity for U.S. Government Obligations. The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 10.01 or the principal or interest received in respect of such obligations. ARTICLE 11 MISCELLANEOUS PROVISIONS SECTION 11.01. Incorporators, Stockholders, Officers and Directors of Issuer Exempt from Individual Liability. No recourse under or upon any obligation, covenant or agreement contained in this Indenture, or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such, or against any past, present or future stockholder, officer or director, as such, of the Issuer or of any successor, either directly or through the Issuer or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities and the Coupons appertaining thereto by the Holders thereof and as part of the consideration for the issue of the Securities and the Coupons appertaining thereto. SECTION 11.02. Provisions of Indenture for the Sole Benefit of Parties and Holders of Securities and Coupons. Nothing in this Indenture, in the Securities or in the Coupons appertaining thereto, expressed or implied, shall give or be construed to give to any person, firm or corporation, other than the parties hereto and their successors and the Holders of the Securities or Coupons, if any, any legal or equitable right, remedy or claim under this Indenture or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the parties hereto and their successors and of the Holders of the Securities or Coupons, if any. 63

SECTION 11.03. Successors and Assigns of Issuer Bound by Indenture. All the covenants, stipulations, promises and agreements contained in this Indenture by or on behalf of the Issuer shall bind its successors and assigns, whether so expressed or not. SECTION 11.04. Notices and Demands on Issuer, Trustee and Holders of Securities and Coupons. Any notice or demand which by any provision of this Indenture is required or permitted to be given or served by the Trustee or by the Holders of Securities or Coupons to or on the Issuer may be given or served by being deposited postage prepaid, first-class mail (except as otherwise specifically provided herein) addressed (until another address of the Issuer is filed by the Issuer with the Trustee) to Texas Instruments Incorporated, Post Office Box 660199, Dallas, Texas 75266-0199, Attn: Secretary. Any notice, direction, request or demand by the Issuer or any Holder of Securities or Coupons to or upon the Trustee shall be deemed to have been sufficiently given or made, for all purposes, if given or made at the Corporate Trust Office, Attn: Corporate Trustee Administration Department. Where this Indenture provides for notice to Holders of Registered Securities, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder entitled thereto, at his or her last address as it appears in the Security register. In any case where notice to such Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice to Holders of Unregistered Securities, such notice shall be sufficiently given to Holders of Unregistered Securities if published in an Authorized Newspaper in London and New York and, if the Unregistered Securities of such series are then listed on the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, in Luxembourg, or in any other required city or, if not practicable, elsewhere in Europe on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for the giving of such notice. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case, by reason of the suspension of or irregularities in regular mail service, it shall be impracticable to mail notice to the Issuer when such notice is required to be given pursuant to any provision of this Indenture, then any manner 64

of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice. In case, by reason of the suspension of or irregularities in regular mail service, it shall be impracticable to mail notice of any event to Holders of Registered Securities when said notice is required to be given pursuant to any provision of this Indenture or of the Securities, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice. Neither the failure to give notice, nor any defect in any notice so given, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice by publication to Holders of Unregistered Securities given as provided above. In case, by reason of the suspension of publication of any Authorized Newspaper or by reason of any other cause, it shall be impossible or impracticable to make publication of any notice to Holders of Unregistered Securities in an Authorized Newspaper or Authorized Newspapers as required by this Indenture or by the Unregistered Securities, then such method of publication or notification to Holders of Unregistered Securities as shall be made in a manner satisfactory to the Trustee shall constitute a sufficient publication of such notice. Neither the failure to give notice by publication to Holders of Unregistered Securities as provided above nor any defect in any notice as published shall affect the sufficiency of any notice mailed to Holders of Registered Securities. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. SECTION 11.05. Officers' Certificates and Opinions of Counsel; Statements to Be Contained Therein. Upon any application or demand by the Issuer to the Trustee to take any action under any of the provisions of this Indenture, the Issuer shall furnish to the Trustee an Officers' Certificate stating that all conditions precedent provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent have been complied with, except that in the case of any such application or demand as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or demand, no additional certificate or opinion need be furnished. 65

Each certificate or opinion provided for in this Indenture and delivered to the Trustee with respect to compliance with a condition or covenant provided for in this Indenture shall include (a) a statement that the person making such certificate or opinion has read such covenant or condition, (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based, (c) a statement that, in the opinion of such person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with and (d) a statement as to whether or not, in the opinion of such person, such condition or covenant has been complied with. Any certificate, statement or opinion of an officer of the Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of or representations by counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters, information with respect to which is in the possession of the Issuer, upon the certificate, statement or opinion of or representations by an officer or officers of the Issuer, unless such counsel knows that the certificate, statement or opinion or representations with respect to the matters upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of an officer of the Issuer or of counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of or representations by an accountant or firm of accountants in the employ of the Issuer, unless such officer or counsel, as the case may be, knows that the certificate or opinion or representations with respect to the accounting matters upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate or opinion of any independent firm of public accountants filed with and directed to the Trustee shall contain a statement that such firm is independent. SECTION 11.06. Payments Due on Saturdays, Sundays and Holidays. If the date of maturity of interest on or principal of the Securities of any series or any Coupons appertaining thereto or the date fixed for redemption or repayment of any such Security or Coupon, or the last day on which a Holder has the right to 66

convert any Security, shall not be a Business Day, then payment of interest or principal, or any conversion, need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date of maturity or the date fixed for redemption or on such last day for conversion, and no interest shall accrue for the period after such date. SECTION 11.07. Conflict of Any Provision of Indenture with Trust Indenture Act of 1939. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with another provision included in this Indenture by operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939, such incorporated provision shall control. SECTION 11.08. New York Law to Govern. This Indenture and each Security and Coupon shall be deemed to be a contract under the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of such State, except as may otherwise be required by mandatory provisions of law. SECTION 11.09. Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an original; but such counterparts shall together constitute but one and the same instrument. SECTION 11.10. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. SECTION 11.11. Securities in a Foreign Currency or in euro. Unless otherwise specified in an Officers' Certificate delivered pursuant to Section 2.03 of this Indenture with respect to a particular series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders of a specified percentage in aggregate principal amount of Securities of all series or all series affected by a particular action at the time Outstanding and, at such time, there are Outstanding Securities of any series which are denominated in a coin or currency other than Dollars (including euro), then the principal amount of Securities of such series which shall be deemed to be Outstanding for the purpose of taking such action shall be that amount of Dollars that could be obtained for such amount at the Market Exchange Rate. For purposes of this Section 11.11, Market Exchange Rate shall mean the noon Dollar buying rate for that currency for cable transfers quoted in The City of New York as certified for customs purposes by the Federal Reserve Bank of New York. If such Market Exchange Rate is not available for any reason with respect to such currency, the Trustee shall use, in its sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York as of the most recent available date, or quotations or 67

rates of exchange from one or more major banks in The City of New York or in the country of issue of the currency in question, which for purposes of the euro shall be Brussels, Belgium, or such other quotations or rates of exchange as the Trustee shall deem appropriate. The provisions of this paragraph shall apply in determining the equivalent principal amount in respect of Securities of a series denominated in a currency other than Dollars in connection with any action taken by Holders of Securities pursuant to the terms of this Indenture. All decisions and determinations of the Trustee regarding the Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Issuer and all Holders. SECTION 11.12. Judgment Currency. The Issuer agrees, to the fullest extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of or interest on the Securities of any series (the "Required Currency") into a currency in which a judgment will be rendered (the "Judgment Currency"), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day next preceding that on which final unappealable judgment is given and (b) its obligations under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, "New York Banking Day" means any day except a Saturday, Sunday or legal holiday in The City of New York or a day on which banking institutions in The City of New York are authorized or required by law or executive order to close. 68

ARTICLE 12 SUBORDINATION OF SECURITIES SECTION 12.01. Agreement of Subordination. The Issuer covenants and agrees, and each holder of Securities issued hereunder by his acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article 12; and each Securityholder, whether upon original issue or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions. The payment of the principal of, premium, if any, and interest on all Securities issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred. No provision of this Article 12 shall prevent the occurrence of any default or Event of Default hereunder. SECTION 12.02. Payments to Securityholders. In the event and during the continuation of any default in the payment of principal, premium, interest or any other payment due on any Senior Indebtedness continuing beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior Indebtedness, then, unless and until such default shall have been cured or waived or shall have ceased to exist, no payment shall be made by the Issuer with respect to the principal of, or premium, if any, or interest on the Securities, except sinking fund payments made by the acquisition of Securities under Section 13.06 prior to the happening of such default and payments made pursuant to Article 10 hereof from monies deposited with the Trustee pursuant thereto prior to the happening of such default. Upon any payment by the Issuer, or distribution of assets of the Issuer of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Issuer, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness shall first be paid in full, or payment thereof provided for in money in accordance with its terms, before any payment is made on account of the principal (and premium, if any) or interest on the Securities (except payments made pursuant to Article 10 hereof from monies deposited with the Trustee pursuant thereto prior to the happening of such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding-up or liquidation or reorganization any payment by the Issuer, or distribution of assets of the Issuer of any kind or 69

character, whether in cash, property or securities, to which the holders of the Securities or the Trustee would be entitled, except for the provisions of this Article 12, shall (except as aforesaid) be paid by the Issuer or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the holders of the Securities or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, as calculated by the Issuer) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in money or money's worth, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution is made to the holders of the Securities or to the Trustee. In the event that, notwithstanding the foregoing, any payment or distribution of assets of the Issuer of any kind or character, whether in cash, property or securities, prohibited by the foregoing, shall be received by the Trustee or the holders of the Securities before all Senior Indebtedness is paid in full, or provision is made for such payment in money in accordance with its terms, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Issuer, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in money in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness. For purposes of this Article 12, the words, "cash, property or securities" shall not be deemed to include shares of stock of the Issuer as reorganized or readjusted, or securities of the Issuer or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article 12 with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment, and (ii) the rights of the holders of the Senior Indebtedness (other than leases) and of leases which are assumed are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Issuer with, or the merger of the Issuer into, another corporation or the liquidation or dissolution of 70

the Issuer following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article 9 hereof shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 12.02 if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article 9 hereof. Nothing in this Section 12.02 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.06. SECTION 12.03. Subrogation of Securities. Subject to the payment in full of all Senior Indebtedness, the rights of the holders of the Securities shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Issuer applicable to the Senior Indebtedness until the principal of (and premium, if any) and interest on the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the holders of the Securities or the Trustee would be entitled except for the provisions of this Article 12, and no payment over pursuant to the provisions of this Article 12, to or for the benefit of the holders of Senior Indebtedness by holders of the Securities or the Trustee, shall, as between the Issuer, its creditors other than holders of Senior Indebtedness, and the holders of the Securities, be deemed to be a payment by the Issuer to or on account of the Senior Indebtedness. It is understood that the provisions of this Article 12 are and are intended solely for the purpose of defining the relative rights of the holders of the Securities, on the one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing contained in this Article 12 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Issuer, its creditors other than the holders of Senior Indebtedness, and the holders of the Securities, the obligation of the Issuer, which is absolute and unconditional, to pay to the holders of the Securities the principal of (and premium, if any) and interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Securities and creditors of the Issuer other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 12 of the holders of Senior Indebtedness in respect of cash, property or securities of the Issuer received upon the exercise of any such remedy. Upon any payment or distribution of assets of the Issuer referred to in this Article 12, the Trustee, subject to the provisions of Section 6.01, and the holders 71

of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the holders of the Securities, for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 12. SECTION 12.04. Authorization by Securityholders. Each holder of a Security by his acceptance thereof authorizes and directs the Trustee in his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 12 and appoints the Trustee his attorney-in-fact for any and all such purposes. SECTION 12.05. Notice to Trustee. The Issuer shall give prompt written notice to a Responsible Officer of the Trustee of any fact known to the Issuer which would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this Article 12. Notwithstanding the provisions of this Article 12 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this Article 12, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office of the Trustee from the Issuer or a holder or holders of Senior Indebtedness or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.01, shall be entitled in all respects to assume that no such facts exist; provided that if on a date not fewer than three Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the principal of (or premium, if any) or interest on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 12.05, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such prior date. Notwithstanding anything to the contrary hereinbefore set forth, nothing shall prevent any payment by the Issuer or the Trustee to the Securityholders of monies in connection with a redemption of Securities if (i) notice of such redemption has been given pursuant to Article 13 or Section 10.01 hereof prior to 72

the receipt by the Trustee of written notice as aforesaid, and (ii) such notice of redemption is given not earlier than 60 days before the redemption date. The Trustee conclusively shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 12, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 12, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. SECTION 12.06. Trustee's Relation to Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 12 in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness and nothing elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article 12, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to holders of Securities, the Issuer or any other Person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article 12 or otherwise. SECTION 12.07. No Impairment of Subordination. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Issuer with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. 73

SECTION 12.08. Rights of Trustee. Nothing in this Article 12 shall apply to claims of or payments to, the Trustee pursuant to Section 6.06 or 10.05. ARTICLE 13 REDEMPTION OF SECURITIES AND SINKING FUNDS SECTION 13.01. Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series, except as otherwise specified, as contemplated by Section 2.03 for Securities of such series. SECTION 13.02. Notice of Redemption; Partial Redemptions. Notice of redemption to the Holders of Registered Securities of any series to be redeemed as a whole or in part at the option of the Issuer shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such Holders of Securities of such series at their last addresses as they shall appear upon the registry books. Notice of redemption to the Holders of Unregistered Securities to be redeemed as a whole or in part, who have filed their names and addresses with the Trustee pursuant to Section 4.01, shall be given by mailing notice of such redemption, by first class mail, postage prepaid, at least 30 days and not more than 60 prior to the date fixed for redemption, to such Holders at such addresses as were so furnished to the Trustee (and, in the case of any such notice given by the Issuer, the Trustee shall make such information available to the Issuer for such purpose). Notice of redemption to all other Holders of Unregistered Securities shall be published in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and in an Authorized Newspaper in London (and, if required by Section 3.08, in an Authorized Newspaper in Luxembourg), in each case, once in each of three successive calendar weeks, the first publication to be not less than 30 nor more than 60 days prior to the date fixed for redemption. Any notice which is given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure to give notice or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series. The notice of redemption to each such Holder shall specify the principal amount of each Security of such series held by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place or places of payment, that payment will be made upon presentation and surrender of such Securities and, 74

in the case of Securities with Coupons attached thereto, of all Coupons appertaining thereto maturing after the date fixed for redemption, that such redemption is pursuant to the mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid as specified in such notice and that on and after said date interest thereon or on the portions thereof to be redeemed will cease to accrue and shall also specify, if applicable, the Conversion Price then in effect and the date on which the right to convert such Securities or the portions thereof to be redeemed will expire. In case any Security of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued. The notice of redemption of Securities of any series to be redeemed at the option of the Issuer shall be given by the Issuer or, at the Issuer's request, by the Trustee in the name and at the expense of the Issuer. On or before the redemption date specified in the notice of redemption given as provided in this Section, the Issuer will deposit with the Trustee or with one or more paying agents (or, if the Issuer is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 3.04) an amount of money sufficient to redeem on the redemption date all the Securities of such series so called for redemption (other than those theretofore surrendered for conversion into Common Stock) at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any paying agent or so segregated and held in trust for the redemption of such Security shall be paid to the Issuer upon the Issuer's request, or, if then held by the Issuer, shall be discharged from such trust. The Issuer will deliver to the Trustee at least 70 days prior to the date fixed for redemption (unless a shorter time period shall be acceptable to the Trustee) an Officers' Certificate (which need not comply with Section 11.05) stating the aggregate principal amount of Securities to be redeemed. In case of a redemption at the election of the Issuer prior to the expiration of any restriction on such redemption, the Issuer shall deliver to the Trustee, prior to the giving of any notice of redemption to Holders pursuant to this Section, an Officers' Certificate stating that such restriction has been complied with. If less than all the Securities of a series are to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate and fair, Securities of such Series to be redeemed. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or 75

any multiple thereof. The Trustee shall promptly notify the Issuer in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities of any series shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed. If any Security selected for partial redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Upon any redemption of less than all the Securities, the Issuer and the Trustee may treat as Outstanding Securities surrendered for conversion during the period of 15 days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the unconverted portion of any Security converted in part during such period. SECTION 13.03. Conversion Arrangement on Call for Redemption. In connection with any redemption of Securities, the Issuer may arrange for the purchase and conversion in accordance with Article 14 of any Securities called for redemption by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the paying agent, in trust for the Securityholders, on or before the close of business on the redemption date, an amount that, together with any amounts deposited with the paying agent by the Issuer for the redemption of such Securities, is not less than the redemption price of such Securities together with interest to and including the redemption date. Notwithstanding anything to the contrary contained in this Article 13, the obligation of the Issuer to pay the redemption price of such Securities shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, any Securities not duly surrendered for conversion in accordance with Article 14 by the Holders thereof may, at the option of the Issuer, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 14) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the redemption date, subject to payment of the above amount as aforesaid. The paying agent shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it in the same manner as it would moneys deposited with it by the Issuer for the redemption of Securities. Without the paying agent's and the Trustee's prior written consent, no arrangement between the Issuer and such purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the paying agent or the Trustee as set forth in this Indenture, and the Issuer agrees to 76

indemnify the paying agent and the Trustee from, and hold them harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Issuer and such purchasers, including the costs and expenses incurred by the paying agent or the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture. SECTION 13.04. Payment of Securities Called for Redemption. If notice of redemption has been given as above provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for redemption, and on and after said date (unless the Issuer shall default in the payment of such Securities at the redemption price, together with interest accrued to said date) interest on the Securities or portions of Securities so called for redemption shall cease to accrue, and the unmatured Coupons, if any, appertaining thereto shall be void, and, except as provided in Sections 6.05 and 10.04, such Securities shall cease from and after the date fixed for redemption to be convertible into Common Stock, if applicable, and to be entitled to any benefit or security under this Indenture, and the Holders thereof shall have no right in respect of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender of such Securities at a place of payment specified in said notice, together with all Coupons, if any, appertaining thereto maturing after the date fixed for redemption, said Securities or the specified portions thereof shall be paid and redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided, that payment of interest becoming due on or prior to the date fixed for redemption shall be payable in the case of Securities with Coupons attached thereto, to the Holders of the Coupons for such interest upon surrender thereof, and in the case of Registered Securities, to the Holders of such Registered Securities registered as such on the relevant record date subject to the terms and provisions of Sections 2.03 and 2.07 hereof. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by such Security and, if applicable, such Security shall remain convertible into Common Stock until the principal of such Security shall have been paid or duly provided for. 77

If any Security with Coupons attached thereto is surrendered for redemption and is not accompanied by all appurtenant Coupons maturing after the date fixed for redemption, the surrender of such missing Coupon or Coupons may be waived by the Issuer and the Trustee if there be furnished to each of them such security or indemnity as they may require to save each of them harmless. Upon presentation of any Security redeemed in part only, the Issuer shall execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Issuer, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented. SECTION 13.05. Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in an Officers' Certificate delivered to the Trustee at least 40 days prior to the last date on which notice of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or (b) an entity specifically identified in such written statement as directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer. SECTION 13.06. Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of the Securities of any series is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of the Securities of any series is herein referred to as an "optional sinking fund payment". The date on which a sinking fund payment is to be made is herein referred to as the "sinking fund payment date". In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Issuer may at its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the mandatory sinking fund) by the Issuer or receive credit for Securities of such series (not previously so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10 and, if applicable, receive credit for Securities (not previously so credited) converted into Common Stock and so delivered to the Trustee for cancellation, (b) receive credit for optional sinking fund payments (not previously so credited) made pursuant to this Section, or (c) receive credit for Securities of such series (not previously so credited) redeemed by the Issuer through any optional redemption provision contained in the terms of such series. Securities so delivered or credited shall be 78

received or credited by the Trustee at the sinking fund redemption price specified in such Securities. On or before the 60th day next preceding each sinking fund payment date for any series, the Issuer will deliver to the Trustee an Officers' Certificate (which need not contain the statements required by Section 11.05) (a) specifying the portion of the mandatory sinking fund payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities of such series and the basis for such credit, (b) stating that none of the Securities of such series has theretofore been so credited, (c) stating that no defaults in the payment of interest or Events of Default with respect to such series have occurred (which have not been waived or cured) and are continuing and (d) stating whether or not the Issuer intends to exercise its right to make an optional sinking fund payment with respect to such series and, if so, specifying the amount of such optional sinking fund payment which the Issuer intends to pay on or before the next succeeding sinking fund payment date. Any Securities of such series to be credited and required to be delivered to the Trustee in order for the Issuer to be entitled to credit therefor as aforesaid which have not theretofore been delivered to the Trustee shall be delivered for cancellation pursuant to Section 2.10 to the Trustee with such Officers' Certificate (or reasonably promptly thereafter if acceptable to the Trustee). Such Officers' Certificate shall be irrevocable and upon its receipt by the Trustee the Issuer shall become unconditionally obligated to make all the cash payments or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Issuer, on or before any such 60th day, to deliver such Officers' Certificate and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable election of the Issuer (i) that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof and (ii) that the Issuer will make no optional sinking fund payment with respect to such series as provided in this Section. If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or the equivalent thereof in any Foreign Currency or in euro or a lesser sum in Dollars or in any Foreign Currency or in euro if the Issuer shall so request) with respect to the Securities of any particular series, such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If such amount shall be $50,000 (or the equivalent thereof in any Foreign Currency or euro) or less and the Issuer makes no such request then it shall be carried over until a sum in excess of 79

$50,000 (or the equivalent thereof in any Foreign Currency or euro) is available. The Trustee shall select, in the manner provided in Section 13.02, for redemption on such sinking fund payment date a sufficient principal amount of Securities of such series to absorb said cash, as nearly as may be, and shall (if requested in writing by the Issuer) inform the Issuer of the serial numbers of the Securities of such series (or portions thereof) so selected. Securities shall be excluded from eligibility for redemption under this Section if they are identified by registration and certificate number in an Officers' Certificate delivered to the Trustee at least 60 days prior to the sinking fund payment date as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or (b) an entity specifically identified in such Officers' Certificate as directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer. The Trustee, in the name and at the expense of the Issuer (or the Issuer, if it shall so request the Trustee in writing), shall cause notice of redemption of the Securities of such series to be given in substantially the manner provided in Section 13.02 (and with the effect provided in Section 13.04) for the redemption of Securities of such series in part at the option of the Issuer. The amount of any sinking fund payments not so applied or allocated to the redemption of Securities of such series shall be added to the next cash sinking fund payment for such series and, together with such payment, shall be applied in accordance with the provisions of this Section. Any and all sinking fund moneys held on the stated maturity date of the Securities of any particular series (or earlier, if such maturity is accelerated), which are not held for the payment or redemption of particular Securities of such series, shall be applied, together with other moneys, if necessary, sufficient for the purpose, to the payment of the principal of, and interest on, the Securities of such series at maturity. The Issuer's obligation to make a mandatory or optional sinking fund payment shall automatically be reduced by an amount equal to the sinking fund redemption price allocable to any Securities or portions thereof called for redemption pursuant to the preceding paragraph on any sinking fund payment date and converted into Common Stock; provided, that, if the Trustee is not the conversion agent for the Securities, the Issuer or such conversion agent shall give the Trustee written notice prior to the date fixed for redemption of the principal amount of Securities or portions thereof so converted. On or before each sinking fund payment date, the Issuer shall pay to the Trustee in cash or shall otherwise provide for the payment of all interest accrued to the date fixed for redemption on Securities to be redeemed on the next following sinking fund payment date. The Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking fund moneys or give any notice of redemption of Securities for such series by operation of the sinking fund during the continuance of a default in 80

payment of interest on such Securities or of any Event of Default except that, where the mailing of notice of redemption of any Securities shall theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Issuer a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance of such default or Event of Default, be deemed to have been collected under Article 5 and held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Section 5.10, or the default cured on or before the 60th day preceding the sinking fund payment date in any year, such moneys shall thereafter be applied on the next succeeding sinking fund payment date in accordance with this Section to the redemption of such Securities. ARTICLE 14 CONVERSION OF SECURITIES SECTION 14.01. Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which are convertible into Common Stock, except as otherwise specified, as contemplated by Section 2.03 for Securities of such series. SECTION 14.02. Exercise of Conversion Privilege. In order to exercise the conversion privilege, the Holder of any Security to be converted shall surrender such Security, together with all unmatured Coupons, to the Issuer at any time during usual business hours at its office or agency maintained for the purpose as provided in this Indenture, accompanied by a fully executed written notice, in substantially the form set forth on the reverse of the Security, that the Holder elects to convert such Security or a stated portion thereof constituting a multiple of the minimum authorized denomination thereof, and, if such Security is surrendered for conversion during the period between the close of business on any record date for such Security and the opening of business on the related interest payment date (unless such Security shall have been called for redemption on a redemption date within such period or on such interest payment date), accompanied also by payment of an amount equal to the interest payable on such interest payment date on the portion of the principal amount of the Security being surrendered for conversion. A Holder of any Security on a record date for such Security who converts such Security on the related interest payment date will receive the interest payable on such Security, and such converting Holder need not include a payment for any such interest upon surrender of such Security for conversion. Such notice shall also state the name or names (with address) in 81

which the certificate or certificates for shares of Common Stock shall be issued. Securities and any appurtenant Coupons surrendered for conversion shall (if so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the Holder or his or her attorney duly authorized in writing. As promptly as practicable after the receipt of such notice and the surrender of such Security and any appurtenant Coupons as aforesaid, the Issuer shall, subject to the provisions of Section 14.07, issue and deliver at such office or agency to such Holder, or on his or her written order, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion of Securities in accordance with the provisions of this Article and cash, as provided in Section 14.03, in respect of any fraction of a share of Common Stock otherwise issuable upon such conversion. Such conversion shall be deemed to have been effected immediately prior to the close of business on the date (herein called the "Date of Conversion") on which such notice shall have been received by the Issuer and such Security and any appurtenant Coupons shall have been surrendered as aforesaid, and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on the Date of Conversion the holder or holders of record of the shares represented thereby; provided, however, that any such surrender on any date when the stock transfer books of the Issuer shall be closed shall constitute the Person or Persons in whose name or names the certificate or certificates for such shares are to be issued as the recordholder or holders thereof for all purposes at the opening of business on the next succeeding day on which such stock transfer books are open but such conversion shall nevertheless be at the Conversion Price in effect at the close of business on the date when such Security and any appurtenant Coupons shall have been so surrendered with the conversion notice. In the case of conversion of a portion, but less than all, of a Security, the Issuer shall execute, and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Issuer, a Security or Securities in the aggregate principal amount of the unconverted portion of the Security surrendered. Except as otherwise expressly provided in this Indenture, no payment or adjustment shall be made for interest accrued on any Security (or portion thereof) converted or for dividends or distributions on any Common Stock issued upon conversion of any Security; provided, however, that, in the case of any Securities which are converted after the close of business on a relevant record date and on or prior to the next succeeding interest payment date, installments of interest which are due and payable on the next succeeding interest payment date shall be payable on such interest payment date notwithstanding such conversion (unless such Security shall have been called for redemption on a redemption date after the close of business on such record date and prior to the opening of business on such interest payment date) and such interest (whether or not punctually paid or duly provided for) shall be paid to the 82

Holder of such Securities registered as such at the close of business on the relevant record date according to their terms and the provisions of Section 2.07. If any Security surrendered for conversion shall not be accompanied by all appurtenant Coupons maturing after the Date of Conversion, such Security may be converted after payment in cash by the Holder thereof in an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupons may be waived by the Issuer and any conversion agent if there be furnished to the Issuer and any such conversion agent such security or indemnity as they may require to save each of them harmless. SECTION 14.03. Fractional Interests. No fractions of shares or scrip representing fractions of shares shall be issued upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities so surrendered. If any fraction of a share of Common Stock would, except for the provisions of this Section, be issuable on the conversion of any Security or Securities, the Issuer shall make payment in lieu thereof in an amount of Dollars equal to the value of such fraction computed on the basis of the last sale price of the Common Stock as reported on the Composite Tape for New York Stock Exchange - Listed Stocks (or if not listed or admitted to trading on such Exchange, then on the principal national securities exchange on which the Common Stock is listed or admitted to trading, or, if not listed or admitted to trading on any national securities exchange, then as reported by the National Association of Securities Dealers, Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting information) on the last trading day prior to the Date of Conversion or, if no such sale takes place on such day, the last sale price for such day shall be the average of the closing bid and asked prices regular way on the New York Stock Exchange (or if not listed or admitted to trading on such Exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading, or if not listed or admitted to trading on any national securities exchange, the average of the highest bid and lowest asked prices as reported by the National Association of Securities Dealers, Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting information) (any such last sale price being hereinafter referred to as the "Last Sale Price"). If on such trading day the Common Stock is not quoted by any such organization, the fair value of such Common Stock on such day, as determined by the Board of Directors, shall be used. For the purpose of this Section 14.03, the term "trading day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on which securities are not traded on such exchange or in such market. 83

SECTION 14.04. Adjustment of Conversion Price. The Conversion Price shall be subject to adjustment from time to time as follows: (a) In case the Issuer shall (i) pay a dividend or make a distribution on Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares or (iii) combine its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such action shall be adjusted as provided below so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock which he or she would have or been entitled to receive immediately following such action had such Security been converted immediately prior thereto. An adjustment made pursuant to this subsection (a) shall become effective immediately, except as provided in subsection (e) below, after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. (b) In case the Issuer shall issue rights, warrants or options to all holders of Common Stock entitling them (for a period not exceeding 45 days from the date of such issuance) to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (as determined pursuant to subsection (d) below) of the Common Stock on the record date mentioned below, the Conversion Price shall be adjusted to a price, computed to the nearest cent, so that the same shall equal the price determined by multiplying: (i) the Conversion Price in effect immediately prior to the date of issuance of such rights, warrants or options by a fraction, of which (ii) the numerator shall be (A) the number of shares of Common Stock outstanding on the date of issuance of such rights, warrants or options immediately prior to such issuance, plus (B) the number of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase would purchase at such current market price (determined by multiplying such total number of shares by the exercise price of such rights, warrants or options and dividing the product so obtained by such current market price), and of which (iii) the denominator shall be (A) the number of shares of Common Stock outstanding on the date of issuance of such rights, warrants or options, immediately prior to such issuance, plus (B) the number of additional shares of Common Stock which are so offered for subscription or purchase. 84

Such adjustment shall become effective immediately, except as provided in subsection (e) below, after the record date for the determination of holders entitled to receive such rights, warrants or options. (c) In case the Issuer shall distribute to substantially all holders of Common Stock evidences of indebtedness, equity securities (including equity interests in the Issuer's Subsidiaries) other than Common Stock or other assets (other than cash dividends paid out of earned surplus of the Issuer or, if there shall be no earned surplus, out of net profits for the fiscal year in which the dividend is made and/or the preceding fiscal year), or shall distribute to substantially all holders of Common Stock rights, warrants or options to subscribe to securities (other than those referred to in subsection (b) above), then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the date of such distribution by a fraction of which the numerator shall be the current market price per share (determined as provided in subsection (d) below) of the Common Stock on the record date mentioned below less the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value, and described in a Board Resolution filed with the Trustee) of the portion of the assets, evidences of indebtedness and equity securities so distributed or of such subscription rights, warrants or options applicable to one share of Common Stock, and of which the denominator shall be such current market price per share of the Common Stock. Such adjustment shall become effective immediately, except as provided in subsection (e) below, after the record date for the determination of stockholders entitled to receive such distribution. (d) For the purpose of any computation under subsections (b) and (c) above, the current market price per share of Common Stock on any date shall be deemed to be the average of the Last Sale Prices of a share of Common Stock for the five consecutive trading days commencing not more than 20 trading days before, and ending not later than, the earliest of the date in question and the date before the "ex" date with respect to the issuance or distribution requiring such computation. If on any such trading day the Common Stock is not quoted by any organization referred to in the definition of Last Sale Price in Section 14.03, the fair value of the Common Stock on such day, as determined by the Board of Directors, shall be used. For purposes of this paragraph, the term "'ex' date", when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the principal national securities exchange on which the Common Stock is listed or admitted to trading (or, if not so listed or admitted, on NASDAQ or a similar organization if NASDAQ is no longer reporting trading information) without the right to receive such issuance or distribution. 85

(e) In any case in which this Section shall require that an adjustment be made immediately following a record date, the Issuer may elect to defer the effectiveness of such adjustment (but in no event until a date later than the effective time of the event giving rise to such adjustment), in which case the Issuer shall, with respect to any Security converted after such record date and before such adjustment shall have become effective (i) defer making any cash payment pursuant to Section 14.03 or issuing to the Holder of such Security the number of shares of Common Stock and other capital stock of the Issuer issuable upon such conversion in excess of the number of shares of Common Stock and other capital stock of the Issuer issuable thereupon only on the basis of the Conversion Price prior to adjustment, and (ii) not later than five Business Days after such adjustment shall have become effective, pay to such Holder the appropriate cash payment pursuant to Section 14.03 and issue to such Holder the additional shares of Common Stock and other capital stock of the Issuer issuable on such conversion. (f) No adjustment in the Conversion Price shall be required if Securityholders are to participate in the transaction on a basis and with notice that the Board of Directors determines to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. In addition, no adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Price; provided, that any adjustments which by reason of this subsection (f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. (g) Whenever the Conversion Price is adjusted as herein provided, the Issuer shall promptly (i) file with the Trustee and each conversion agent an Officers' Certificate setting forth the Conversion Price after such adjustment and setting forth in reasonable detail the facts requiring such adjustment and the calculations on which the adjustment is based, which certificate shall be conclusive evidence of the correctness of such adjustment and which shall be made available by the Trustee to the Holders of Securities for inspection thereof and (ii) mail or cause to be mailed a notice of such adjustment, setting forth the adjusted Conversion Price and the date on which such adjustment became or becomes effective, to each Holder of Securities at his or her address as the same appears on the registry books of the Issuer. Anything in this Section to the contrary notwithstanding, the Issuer shall be entitled to make such reductions in the Conversion Price, in addition to those required by this Section, as it in its discretion shall determine to be advisable in 86

order that any stock dividend, subdivision or combination of shares, distribution of rights, warrants or options to purchase stock or securities, distribution of securities convertible into or exchangeable for stock or distribution of other assets (other than cash dividends) hereafter made by the Issuer to its stockholders shall not be taxable. SECTION 14.05. Continuation of Conversion Privilege in Case of Reclassification, Reorganization, Change, Merger, Consolidation or Sale of Assets. In case of any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in case of any consolidation of the Issuer with, or merger of the Issuer with or into, any other Person, any merger of another Person into the Issuer (other than a merger which does not result in any reclassification, change, conversion, exchange or cancellation of outstanding shares of Common Stock of the Issuer) or any sale or transfer of all or substantially all of the assets of the Issuer, the Issuer, or the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture complying with the provisions of Article 9, in form satisfactory to the Trustee, providing that the Holder of each Security then Outstanding shall have the right thereafter to convert such Security only into the kind and amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock of the Issuer into which such Security might have been converted immediately prior to such reclassification, change, consolidation, merger, sale or transfer, assuming such holder of Common Stock of the Issuer (a) is not a Person with which the Issuer consolidated or into which the Issuer merged or which merged into the Issuer or to which such sale or transfer was made, as the case may be ("constituent Person"), or an affiliate of a constituent Person and (b) failed to exercise his or her rights of an election, if any, as to the kind or amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, sale or transfer (provided, that, if the kind or amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, sale or transfer is not the same for each share of Common Stock of the Issuer held immediately prior to such reclassification, change, consolidation, merger, sale or transfer by other than a constituent Person or an affiliate thereof and in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, sale or transfer by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Such supplemental indenture shall provide for adjustments which, for events subsequent to the 87

effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. If, in the case of any such reclassification, change, consolidation, merger, sale or transfer, the stock or other securities and property (including cash) receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and property (including cash) of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, sale or transfer, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales or transfers. Notice of the execution of each such supplemental indenture shall be mailed to each Holder of Securities at his or her address as the same appears on the registry books of the Issuer. Neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or securities or property or cash receivable by Holders of Securities upon the conversion of their Securities after any such reclassification, change, consolidation, merger, sale or transfer or to any adjustment to be made with respect thereto, but, subject to the provisions of Sections 6.11 and 6.02, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers' Certificate (which the Issuer shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. SECTION 14.06. Notice of Certain Events. In case: (a) the Issuer shall declare a dividend (or any other distribution) payable to the holders of Common Stock (other than cash dividends paid out of the earned surplus of the Issuer or, if there shall be no earned surplus, out of net profits for the fiscal year in which the dividend is made and/or the preceding fiscal year, and dividends payable in Common Stock); or (b) the Issuer shall authorize the granting to the holders of Common Stock of rights, warrants or options to subscribe for or purchase any shares of stock of any class or of any other rights, warrants or options; or 88

(c) the Issuer shall authorize any reclassification or change of the Common Stock (other than a subdivision or combination of its oustanding shares of Common Stock or a change in par value, or from par value to no par value, or from no par value to par value), or any consolidation or merger to which the Issuer is a party and for which approval of any stockholders of the Issuer is required, or the sale or transfer of all or substantially all the property or business of the Issuer; or (d) there shall be proposed any voluntary or involuntary dissolution, liquidation or winding-up of the Issuer; then, the Issuer shall cause to be filed with the Trustee, and, if other than the Corporate Trust Office of the Trustee, at the office or agency maintained for the purpose of conversion of the Securities as provided in Section 3.02, and shall cause to be mailed to each Holder of Securities, at his or her address as it shall appear on the registry books of the Issuer, as promptly as possible but in any event at least 20 days before the date hereinafter specified (or the earlier of the dates hereinafter specified, in the event that more than one date is specified), a notice stating the date on which (i) a record is expected to be taken for the purpose of such dividend, distribution, rights, warrants or options, or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, or (ii) such reclassification, change, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective and the date, if any is to be fixed, as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, change, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. SECTION 14.07. Taxes on Conversion. The issuance and delivery of certificates for shares of Common Stock on conversion of Securities shall be made without charge to the converting Holder of Securities for such certificates or for any documentary, stamp or similar taxes payable to the United States of America or any political subdivision or taxing authority thereof in respect of the issuance or delivery of such certificates; provided, however, that the Issuer shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance of certificates for shares of Common Stock, and no such issue or delivery shall be made unless and until the Person requesting such issue or delivery has paid to the Issuer the amount of any such tax or has established, to the satisfaction of the Issuer, that such tax has been paid. SECTION 14.08. Issuer to Provide Common Stock. The Issuer covenants that it will reserve and keep available, free from preemptive rights, out of its 89

authorized but unissued shares, solely for the purpose of issue upon conversion of Securities as herein provided, sufficient shares to provide for the conversion of the Securities from time to time as such Securities are presented for conversion. If any shares of Common Stock to be reserved for the purpose of conversion of Securities hereunder require registration with or approval of any governmental authority under any Federal or State law before such shares may be validly issued or delivered upon conversion, then the Issuer covenants that it will in good faith and as expeditiously as possible endeavor to secure such registration or approval, as the case may be; provided, however, that nothing in this Section shall be deemed to affect in any way the obligations of the Issuer to convert Securities into Common Stock as provided in this Article. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value, if any, of the Common Stock, the Issuer will take all corporate action which may, in the Opinion of Counsel, be necessary in order that the Issuer may validly and legally issue fully paid and non-assessable shares of Common Stock at such adjusted Conversion Price. The Issuer covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be duly and validly issued and fully paid and non-assessable by the Issuer and free of preemptive rights and that, if the Common Stock is then listed on any national securities exchange, the shares of Common Stock which may be issued upon conversion of Securities will be similarly listed at the time of such issuance. SECTION 14.09. Disclaimer of Responsibility for Certain Matters. Neither the Trustee nor any conversion agent or agent of the Trustee shall at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the Officers' Certificate referred to in Section 14.04(g) or 14.05, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee nor any conversion agent nor any agent of the Trustee shall be accountable with respect to the validity, registration, listing, or value (or the kind or amount) of any shares of Common Stock, or of any securities or cash or other property, which may at any time be issued or delivered upon the conversion of any Security; and neither the Trustee nor any agent of the Trustee nor any conversion agent makes any representation with respect thereto. Neither the Trustee nor any conversion agent nor any agent of the Trustee shall be responsible for any failure of the Issuer to make any cash payment or to issue, register the transfer of or deliver any shares of Common Stock or stock certificates or other securities or property upon the surrender of any 90

Security and any appurtenant Coupons for the purpose of conversion or, subject to Sections 6.11 and 6.02, to comply with any of the covenants of the Issuer contained in this Article. SECTION 14.10. Return of Funds Deposited for Redemption of Converted Securities. Any funds which at any time shall have been deposited by the Issuer or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of and interest on any of the Securities and which shall not be required for such purposes because of the conversion of such Securities, as provided in this Article, shall after such conversion, upon the written request of the Issuer, be repaid to the Issuer by the Trustee or such other paying agent. 91

(REVERSE OF SECURITY) TEXAS INSTRUMENTS INCORPORATED [ ] Note due [ ] 1. Interest. TEXAS INSTRUMENTS INCORPORATED , a Delaware corporation (the "Company"), promises to pay interest on the principal amount of this Security at the rate per annum shown above. Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from [ ]. The Company will pay interest [semi-annually] in arrears on each Interest Payment Date, commencing [ ]. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful. 2. Method of Payment. The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts ("U.S. Legal Tender"). However, the Company may pay principal and interest by wire transfer of Federal funds (provided that the Paying Agent shall have received written wire instructions by no later than the Interest Record Date for such Interest Payment Date), or interest by check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address. 3. Paying Agent. Initially, Citibank, N.A., (the "Trustee") will act as Paying Agent. The Company may change any Paying Agent without notice to the Holders. 4. Indenture. The Company issued the Securities under an Indenture, dated as of July 15, 1996 (the "Indenture"), between the Company and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa- 77bbbb) (the "TIA"), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and holders of Securities are referred to the Indenture and the TIA for a statement of them. The Securities are general obligations of the Company limited in aggregate principal amount to $[ ]. 3

5. Denominations; Transfer; Exchange. The Securities are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not register the transfer of or exchange any Securities or portions thereof selected for redemption, except the unredeemed portion of any Security being redeemed in part. 6. Persons Deemed Owners. The registered Holder of a Security shall be treated as the owner of it for all purposes. 7. Unclaimed Funds. If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease. 8. Legal Defeasance. The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof upon satisfaction of certain conditions specified in the Indenture. 9. Amendment; Supplement; Waiver. Subject to certain exceptions, the Securities and the provision of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not materially and adversely affect the rights of any Holder of a Security. 10. Restrictive Covenant. The Indenture contains a covenant that limits the ability of the Company to merge or sell all or substantially all of its assets. 11. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities then outstanding may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee 4

may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest. 12. Trustee Dealings with Company. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee. 13. No Recourse Against Others. No stockholder, director, officer, or incorporator, as such, of the Company or any of its successors shall have any liability for any obligation of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 14. Authentication. This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security. 15. Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 16. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon. 17. Governing Law. The laws of the State of New York shall govern the Indenture and this Security thereof without regard to principles of conflicts of laws. 5

Method of Payment. The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts ("U.S. Legal Tender"). However, the Company may pay principal and interest by wire transfer of Federal funds (provided that the Paying Agent shall have received written wire instructions by no later than the Interest Record Date for such Interest Payment Date), or interest by check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address. 3. Paying Agent. Initially, Chase Bank of Texas, National Association (the "Trustee") will act as Paying Agent. The Company may change any Paying Agent without notice to the Holders. 4. Indenture. The Company issued the Securities under an Indenture, dated as of December 16, 1999 (the "Indenture"), between the Company and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa- 77bbbb) (the "TIA"), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and holders of Securities are referred to the Indenture and the TIA for a statement of them. The Securities are general obligations of the Company limited in aggregate principal amount to $[ ]. 3

5. Denominations; Transfer; Exchange. The Securities are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Company need not register the transfer of or exchange any Securities or portions thereof selected for redemption, except the unredeemed portion of any Security being redeemed in part. 6. Persons Deemed Owners. The registered Holder of a Security shall be treated as the owner of it for all purposes. 7. Unclaimed Funds. If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease. 8. Legal Defeasance. The Company may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except for certain provisions thereof upon satisfaction of certain conditions specified in the Indenture. 9. Amendment; Supplement; Waiver. Subject to certain exceptions, the Securities and the provision of the Indenture relating to the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not materially and adversely affect the rights of any Holder of a Security. 10. Restrictive Covenant. The Indenture contains a covenant that limits the ability of the Company to merge or sell all or substantially all of its assets. 11. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Securities then outstanding may declare all of the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee 4

may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest. 12. Subordination. Reference is made to the Indenture, including, without limitation, provisions subordinating the payment of principal of and premium, if any, and interest on the Securities to the prior payment in full of all Senior Indebtedness as defined in the Indenture. 13. Trustee Dealings with Company. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company as if it were not the Trustee. 14. No Recourse Against Others. No stockholder, director, officer, or incorporator, as such, of the Company or any of its successors shall have any liability for any obligation of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 15. Authentication. This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security. 16. Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 17. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon. 18. Governing Law. The laws of the State of New York shall govern the Indenture and this Security thereof without regard to principles of conflicts of laws. 5

WARRANT AGREEMENT1 THIS AGREEMENT dated as of between TEXAS INSTRUMENTS INCORPORATED, a corporation duly organized and existing under the laws of the State of Delaware (the "Company"), and , a [bank] [trust company] duly incorporated and existing under the laws of , as Warrant Agent (the "Warrant Agent"), W I T N E S S E T H : [WHEREAS, the Company has entered into an Indenture dated as of July 15, 1996 (the "Senior Indenture") between the Company and Citibank, N.A., as Trustee (the "Senior Indenture Trustee"), and an Indenture dated as of December 16, 1999 (the "Subordinated Indenture") between the Company and Chase Bank of Texas, National Association, as Trustee (the "Subordinated Indenture Trustee") (together the "Trustees" or "Trustee" and "Indentures" or "Indenture"), providing for the issuance from time to time of its unsecured debt securities to be issued in one or more series as provided in the Indenture; and] WHEREAS, the Company proposes to sell [title of such securities being offered] (the "Offered Securities") with one or more warrants (the "Warrants") representing the right to purchase [title of such securities purchasable through exercise of Warrants] (the "Warrant Securities"), the Warrants to be evidenced by warrant certificates issued pursuant to this Agreement (the "Warrant Certificates"); and WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company in connection with the issuance, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the terms and conditions on which they may be issued, transferred, exchanged, exercised and replaced; NOW, THEREFORE, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree as follows: - -------- 1 Complete or modify the provisions of this form as appropriate to reflect the terms of the Warrants and Warrant Securities. Monetary amounts may be in U.S. dollars in a foreign currency or in a composite currency, including but not limited to the euro.

ARTICLE 1 ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT CERTIFICATES SECTION 1.01. Issuance of Warrants. The Warrants shall be evidenced by one or more Warrant Certificates. Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein, to purchase [_____ shares of the Warrant Securities] [ aggregate principal amount of Warrant Securities]. SECTION 1.02. Execution and Delivery of Warrant Certificates. Each Warrant, whenever issued, shall be evidenced by a Warrant Certificate in registered form substantially in the form set forth in Exhibit A hereto, shall be dated and may have such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by its chairman or vice chairman of the Board of Directors, the president, any managing director, or the treasurer of the Company, in each case under its corporate seal, which may but need not be attested by its Secretary or one of its Assistant Secretaries. Such signatures may be manual or facsimile signatures of such authorized officers and may be imprinted or otherwise reproduced on the Warrant Certificates. The corporate seal of the Company may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates. No Warrant Certificate shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been countersigned by the Warrant Agent by manual signature. Such signature by the Warrant Agent upon any Warrant Certificate executed by the Company shall be conclusive evidence, and the only evidence, that the Warrant Certificate so countersigned has been duly issued hereunder. In case any officer of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent, such Warrant Certificates may be countersigned and delivered notwithstanding that the person who signed such Warrant Certificates ceased to be such officer of the Company; and any Warrant 2

Certificate may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution of this Agreement any such person was not such officer. The term "Holder", when used with respect to any Warrant Certificate shall mean any person in whose name at the time such Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose. SECTION 1.03. Issuance of Warrant Certificates. Warrant Certificates evidencing the right to purchase [_____ shares of the Warrant Securities] [an aggregate principal amount not exceeding aggregate principal amount of Warrant Securities] (except as provided in Sections 2.03, 3.02 and 4.01) may be executed by the Company and delivered to the Warrant Agent upon the execution of this Warrant Agreement or from time to time thereafter. The Warrant Agent shall, upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign Warrant Certificates evidencing Warrants representing the right to purchase up to [_____shares of the Warrant Securities] [ aggregate principal amount of Warrant Securities] and shall deliver such Warrant Certificates to or upon the order of the Company. Subsequent to such original issuance of the Warrant Certificates, the Warrant Agent shall countersign a Warrant Certificate only if the Warrant Certificate is issued in exchange or substitution for one or more previously countersigned Warrant Certificates or in connection with their transfer as hereinafter provided or as provided in the antepenultimate paragraph of Section 2.03. Pending the preparation of definitive Warrant Certificates evidencing Warrants, the Company may execute and the Warrant Agent shall countersign and deliver temporary Warrant Certificates evidencing such Warrants (printed, lithographed, typewritten or otherwise produced, in each case in form satisfactory to the Warrant Agent). Such temporary Warrant Certificates shall be issuable substantially in the form of the definitive Warrant Certificates but with such omissions, insertions and variations as may be appropriate for temporary Warrant Certificates, all as may be determined by the Company with the concurrence of the Warrant Agent. Such temporary Warrant Certificates may contain such reference to any provisions of this Warrant Agreement as may be appropriate. Every such temporary Warrant Certificate shall be executed by the Company and shall be countersigned by the Warrant Agent upon the same conditions and in substantially the same manner, and with like effect, as the definitive Warrant Certificates. Without unreasonable delay, the Company shall execute and shall furnish definitive Warrant Certificates and thereupon such temporary Warrant Certificates may be surrendered in exchange therefor without charge pursuant to and subject to the provisions of Section 4.01, and the Warrant Agent shall 3

countersign and deliver in exchange for such temporary Warrant Certificates definitive Warrant Certificates of authorized denominations evidencing a like aggregate number of Warrants evidenced by such temporary Warrant Certificates. Until so exchanged, such temporary Warrant Certificates shall be entitled to the same benefits under this Warrant Agreement as definitive Warrant Certificates. ARTICLE 2 WARRANT PRICE, DURATION AND EXERCISE SECTION 2.01. Warrant Price. Warrant Price. On , the exercise price of each Warrant will be . During the period from , through and including , , the exercise price of each Warrant will be [plus [accrued amortization of the original issue discount] [accrued interest] from , .] On , , the exercise price of each Warrant will be .

Such exercise price of Warrant Securities is referred to in this Agreement as the "Warrant Price". [The original issue discount for each principal amount of Warrant Securities is ]. SECTION 2.02. Duration of Warrants. Subject to Section 4.03(b), each Warrant may be exercised [in whole but not in part] [in whole or in part] [at any time, as specified herein, on or after [the date thereof] [ , ] and at or before [time, location] on , (each day during such period may hereinafter be referred to as an "Exercise Date")] [on [list of specific dates] (each, an "Exercise Date")], or such later date as the Company may designate by notice to the Warrant Agent and the Holders of Warrant Certificates [in registered form and to the beneficial owners of the Global Warrant Certificate] (the "Expiration Date"). Each Warrant not exercised at or before [time, location] on the Expiration Date shall become void, and all rights of the Holder [and any beneficial owners] of the Warrant Certificate evidencing such Warrant under this Agreement shall cease. SECTION 2.03. Exercise of Warrants. [With respect to Warrants evidenced by Warrant Certificates in registered form, during] [During] the period specified in Section 2.02, any whole number of Warrants may be exercised by providing certain information as set forth on the reverse side of the Warrant Certificates evidencing such Warrants and by paying in full [in lawful money of the United States of America] [in applicable currency] [in cash] [by certified check or official bank check or by bank wire transfer, in each case,] [by bank wire transfer] [in immediately available funds,] the Warrant Price for each Warrant exercised [(plus accrued interest, if any, on the Warrant Securities to be issued 4

upon exercise of such Warrant from and including the Interest Payment Date (as defined in the Indenture), if any, in respect of such Warrant Securities immediately preceding the Exercise Date to and including the Exercise Date (unless the Exercise Date is after the Regular Record Date (as defined in the Indenture), if any, for such Interest Payment Date, but on or before the immediately succeeding Interest Payment Date for such Warrant Securities, in which event no such accrued interest shall be payable))] to the Warrant Agent at its corporate trust office at [address] [or at ], provided that such exercise is subject to receipt within five business days of such [payment] [wire transfer] by the Warrant Agent of the Warrant Certificate evidencing each Warrant exercised with the form of election to purchase Warrant Securities set forth on the reverse side of the Warrant Certificate properly completed and duly executed. [Cashless Exercise Option]. The date on which payment in full of the Warrant Price (plus any such accrued interest) is received by the Warrant Agent shall, subject to receipt of the Warrant Certificate as aforesaid, be deemed to be the date on which the Warrant is exercised. The Warrant Agent shall deposit all funds received by it in payment for the exercise of Warrants in an account of the Company maintained with it (or in such other account as may be designated by the Company) and shall advise the Company, by telephone or by facsimile transmission or other form of electronic communication available to both parties, at the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited to its account. The Warrant Agent shall promptly confirm such advice to the Company in writing. If a day on which Warrants may be exercised in the city in which such Warrants are to be exercised shall be a Saturday or Sunday or a day on which banking institutions in such city are authorized or required to be closed, then, notwithstanding any other provision of this Agreement or the Warrant Certificate evidencing such Warrants, but subject to the limitation that no Warrant may be exercised after the Expiration Date, the Warrants shall be exercisable on the next succeeding day which in such city is not a Saturday or Sunday or a day on which banking institutions in such city are authorized or required to be closed. The Warrant Agent shall, from time to time, as promptly as practicable, advise the Company [and the Trustee] in writing of (i) the number of Warrants exercised, (ii) the instructions of each Holder of the Warrant Certificates evidencing such Warrants with respect to delivery of the Warrant Securities to be issued upon such exercise, (iii) delivery of any Warrant Certificates evidencing the balance, if any, of the Warrants remaining after such exercise, and (iv) such other information as the Company or the Trustee shall reasonably require. 5

As soon as practicable after the exercise of any Warrant, but subject to receipt by the Warrant Agent of the Warrant Certificate evidencing such Warrant as provided in this Section, the Company shall issue[, pursuant to the Indenture, in authorized denominations to or upon the order of the Holder of the Warrant Certificate evidencing each Warrant,] the Warrant Securities to which such Holder is entitled, in fully registered form, registered in such name or names as may be directed by such Holder. If fewer than all of the Warrants evidenced by such Warrant Certificate are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign and deliver, a new Warrant Certificate evidencing the number of such Warrants remaining unexercised. The Company shall not be required to pay any stamp or other tax or other governmental charge required to be paid in connection with any transfer involved in the issuance of the Warrant Securities, and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Security until such tax or other charge shall have been paid or it has been established to the Company's satisfaction that no such tax or other charge is due. ARTICLE 3 OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT SECTION 3.01. No Rights as Warrant Securityholder Conferred by Warrants or Warrant Certificates. No Warrant Certificate or Warrant evidenced thereby shall entitle the Holder or any beneficial owner thereof to any of the rights of a holder or beneficial owner of Warrant Securities, including, without limitation, [the right to receive the payment of principal of (premium, if any) or interest, if any, on Warrant Securities or to enforce any of the covenants in the Indenture] [the right to receive dividend payments on the Warrant Securities or any voting rights]. SECTION 3.02. Lost, Mutilated, Stolen or Destroyed Warrant Certificates. Upon receipt by the Warrant Agent of evidence reasonably satisfactory to it and the Company of the ownership of and the loss, mutilation, theft or destruction of any Warrant Certificate and of such security or indemnity as may be required by the Company and the Warrant Agent to hold each of them and any agent of them harmless and, in the case of mutilation of a Warrant Certificate, upon surrender thereof to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, mutilated, stolen or destroyed Warrant Certificate, a new Warrant Certificate of the same tenor and evidencing a like number of Warrants. Upon the 6

issuance of any new Warrant Certificate under this Section, the Company may require the payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant to this Section in lieu of any lost, mutilated, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement of lost, mutilated, stolen or destroyed Warrant Certificates. SECTION 3.03. Enforcement of Rights. Notwithstanding any of the provisions of this Agreement, any Holder of a Warrant Certificate, without the consent of the Warrant Agent, the relevant Trustee, the holder of any Offered Securities or the Holder of any other Warrant Certificate, may, in its own behalf and for its own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, its right to exercise its Warrants in the manner provided in its Warrant Certificate and in this Agreement. SECTION 3.04. Merger, Consolidation, Conveyance or Transfer. (a) If at any time there shall be a merger or consolidation of the Company or a conveyance or transfer of its property and assets substantially as an entirety [as permitted under the Indenture], then in any such event the successor or assuming corporation referred to therein shall succeed to and be substituted for the Company, with the same effect[, subject to the Indenture,] as if it had been named herein and in the Warrant Certificates as the Company; the Company shall thereupon, except in the case of a transfer by way of lease, be relieved of any further obligation hereunder and under the Warrants and the Warrant Certificates, and the Company as the predecessor corporation, except in the case of a transfer by way of lease, may thereupon or at any time thereafter be dissolved, wound up or liquidated. Such successor or assuming corporation may thereupon cause to be signed, and may issue either in its own name or in the name of the Company, Warrant Certificates evidencing any or all of the Warrants issuable hereunder which theretofore shall not have been signed by the Company, and may execute and deliver Warrant Securities in its own name[, pursuant to the Indenture], in fulfillment of its obligations to deliver Warrant Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same legal rank and benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Warrants 7

had been issued at the date of the execution hereof. In any case of any such merger, consolidation, conveyance or transfer, such changes in phraseology and form (but not in substance) may be made in the Warrant Certificates representing the Warrants thereafter to be issued as may be appropriate. (b) The Warrant Agent may receive a written opinion of legal counsel (who shall be acceptable to the Warrant Agent) as conclusive evidence that any such merger, consolidation, conveyance or transfer complies with the provisions of this Section and the Indentures. [Add Anti-Dilution provisions as necessary.] ARTICLE 4 EXCHANGE AND TRANSFER SECTION 4.01. Exchange and Transfer. (a) Upon surrender at the corporate trust office of the Warrant Agent at [address] [or ], Warrant Certificates evidencing Warrants may be exchanged for Warrant Certificates in other authorized denominations evidencing such Warrants or the transfer thereof may be registered in whole or in part; provided, however, that such other Warrant Certificates shall evidence the same aggregate number of Warrants as the Warrant Certificates so surrendered. (b) The Warrant Agent shall keep, at its corporate trust office at [address] [and at ], books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates and exchanges and transfers of outstanding Warrant Certificates upon surrender of such Warrant Certificates to the Warrant Agent at its corporate trust office at [address] [or ] for exchange or registration of transfer, properly endorsed [or accompanied by appropriate instruments of registration of transfer and written instructions for transfer, all in form satisfactory to the Company and the Warrant Agent.] (c) No service charge shall be made for any exchange or registration of transfer of Warrant Certificates, but the Company may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in connection with any such exchange or registration of transfer. (d) Whenever any Warrant Certificates are so surrendered for exchange or registration of transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled thereto a Warrant Certificate or Warrant Certificates, duly authorized and executed by the 8

Company, as so requested. The Warrant Agent shall not effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate, evidencing a fraction of a Warrant or a number of full Warrants and a fraction of a Warrant. (e) All Warrant Certificates issued upon any exchange or registration of transfer of Warrant Certificates shall be the valid obligations of the Company, evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for such exchange or registration or transfer. SECTION 4.02. Treatment of Holders of Warrant Certificates. Each Holder of a Warrant Certificate, by accepting the same, consents and agrees with the Company, the Warrant Agent and every subsequent Holder of such Warrant Certificate that until the transfer of such Warrant Certificate is registered on the books of such Warrant Agent, the Company and the Warrant Agent may treat the registered Holder of such Warrant Certificate as the absolute owner thereof for any purpose and as the person entitled to exercise the rights represented by the Warrants evidenced thereby, any notice to the contrary notwithstanding. SECTION 4.03. Cancellation of Warrant Certificates. [(a)] Any Warrant Certificate surrendered for exchange or registration of transfer or exercise of the Warrants evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent, and all Warrant Certificates surrendered or so delivered to the Warrant Agent shall be promptly cancelled by the Warrant Agent and shall not be reissued and, except as expressly permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor or in lieu thereof. The Warrant Agent shall cause all cancelled Warrant Certificates to be destroyed and shall deliver a certificate of such destruction to the Company. [(b) If the Company notifies the relevant Trustee of its election to redeem [, as a whole but not in part,] the Warrant Securities pursuant to the Indenture or the terms thereof, the Company may elect, and shall give notice to the Warrant Agent of its election, to cancel the unexercised Warrants, the Warrant Certificates and the rights evidenced thereby.

All of the terms and provisions with respect to such powers and authority contained in the Warrant Certificates are subject to and governed by the terms and provisions hereof. SECTION 5.02. Conditions of Warrant Agent's Obligations. The Warrant Agent accepts its obligations herein set forth upon the terms and conditions hereof, including the following, to all of which the Company agrees and to all of which the rights hereunder of the Holders from time to time of the Warrant Certificates shall be subject: (a) Compensation and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation to be agreed upon with the Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket expenses (including reasonable attorneys' fees) incurred by the Warrant Agent without negligence, bad faith or breach of this Agreement on its part in connection with the services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Warrant Agent, arising out of or in connection with its acting as Warrant Agent hereunder, as well as the reasonable costs and expenses of defending against any claim of such liability. (b) Agent for the Company. In acting under this Agreement and in connection with the Warrants and the Warrant Certificates, the Warrant Agent is acting solely as agent of the Company and does not assume any obligation or relationship of agency or trust for or with any of the Holders of Warrant Certificates or beneficial owners of Warrants. (c) Counsel. The Warrant Agent may consult with counsel satisfactory to it in its reasonable judgment, and the advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or 10

omitted by it hereunder in good faith and in accordance with the advice of such counsel. (d) Documents. The Warrant Agent shall be protected and shall incur no liability for or in respect of any action taken or thing suffered by it in reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other paper or document reasonably believed by it to be genuine and to have been presented or signed by the proper parties. (e) Certain Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner of, or acquire any interest in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted by applicable law, it or they may engage or be interested in any financial or other transaction with the Company and may act on, or as depositary, trustee or agent for, any committee or body of holders of Warrant Securities or other obligations of the Company as freely as if it were not the Warrant Agent hereunder. [Nothing in this Warrant Agreement shall be deemed to prevent the Warrant Agent from acting as Trustee under the Indenture.] (f) No Liability for Interest. The Warrant Agent shall have no liability for interest on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates. (g) No Liability for Invalidity. The Warrant Agent shall not be under any responsibility with respect to the validity or sufficiency of this Agreement or the execution and delivery hereof (except the due authorization to execute this Agreement and the due execution and delivery hereof by the Warrant Agent) or with respect to the validity or execution of any Warrant Certificates (except its countersignature thereof). (h) No Liability for Recitals. The recitals contained herein shall be taken as the statements of the Company and the Warrant Agent assumes no liability for the correctness of the same. (i) No Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as are herein and in the Warrant Certificates specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrant Certificates against the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which may tend to involve it in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it. The Warrant Agent shall not be accountable or under any duty or responsibility for the use by the Company of any of the Warrant Certificates countersigned by the Warrant Agent and delivered by 11

it to the Company pursuant to this Agreement or for the application by the Company of the proceeds of the Warrant Certificates. The Warrant Agent shall have no duty or responsibility in case of any default by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in the case of the receipt of any written demand from a Holder of a Warrant Certificate with respect to such default, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or, except as provided in Section 6.02, to make any demand upon the Company. SECTION 5.03. Resignation and Appointment of Successor. (a) The Company agrees, for the benefit of the Holders from time to time of the Warrant Certificates, that there shall at all times be a Warrant Agent hereunder until all the Warrants have been exercised or are no longer exercisable. (b) The Warrant Agent may at any time resign as such by giving written notice of its resignation to the Company, specifying the desired date on which its resignation shall become effective; provided, however, that such date shall be not less than 90 days after the date on which such notice is given unless the Company agrees to accept shorter notice. Upon receiving such notice of resignation, the Company shall promptly appoint a successor Warrant Agent (which shall be a bank or trust company in good standing, authorized under the laws of the jurisdiction of its organization to exercise corporate trust powers) by written instrument in duplicate signed on behalf of the Company, one copy of which shall be delivered to the resigning Warrant Agent and one copy to the successor Warrant Agent. The Company may, at any time and for any reason, remove the Warrant Agent and appoint a successor Warrant Agent (qualified as aforesaid) by written instrument in duplicate signed on behalf of the Company and specifying such removal and the date when it is intended to become effective, one copy of which shall be delivered to the Warrant Agent being removed and one copy to the successor Warrant Agent. Any resignation or removal of the Warrant Agent and any appointment of a successor Warrant Agent shall become effective upon acceptance of appointment by the successor Warrant Agent as provided in this subsection (b). In the event a successor Warrant Agent has not been appointed and accepted its duties within 90 days of the Warrant Agent's notice of resignation, the Warrant Agent may apply to any court of competent jurisdiction for the designation of a successor Warrant Agent. Upon its resignation or removal, the Warrant Agent shall be entitled to the payment by the Company of the compensation and to the reimbursement of all reasonable out-of-pocket expenses (including reasonable attorneys' fees) incurred by it hereunder as agreed to in Section 5.02(a). 12

(c) The Company shall remove the Warrant Agent and appoint a successor Warrant Agent if the Warrant Agent (i) shall become incapable of acting, (ii) shall be adjudged bankrupt or insolvent, (iii) shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, (iv) shall consent to, or shall have had entered against it a court order for, any such relief or to the appointment of or taking possession by any such official in any involuntary case or other proceedings commenced against it, (v) shall make a general assignment for the benefit of creditors or (vi) shall fail generally to pay its debts as they become due. Upon the appointment as aforesaid of a successor Warrant Agent and acceptance by it of such appointment, the predecessor Warrant Agent shall, if not previously disqualified by operation of law, cease to be Warrant Agent hereunder. (d) Any successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor and the Company an instrument accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance, shall become vested with all the authority, rights, powers, immunities, duties and obligations of such predecessor with like effect as if originally named as Warrant Agent hereunder, and such predecessor shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be entitled to receive, all monies, securities and other property on deposit with or held by such predecessor as Warrant Agent hereunder. (e) Any corporation into which the Warrant Agent hereunder may be merged or converted or any corporation with which the Warrant Agent may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or substantially all the assets and business of the Warrant Agent, provided that it shall be qualified as aforesaid, shall be the successor Warrant Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto. 13

WARRANT AGREEMENT1 THIS AGREEMENT dated as of between TEXAS INSTRUMENTS INCORPORATED, a corporation duly organized and existing under the laws of the State of Delaware (the "Company"), and , a [bank] [trust company] duly incorporated and existing under the laws of , as Warrant Agent (the "Warrant Agent"), Bracketed language here and throughout this Agreement should be inserted as follows: 1. If Warrants are immediately detachable from the Offered Securities; and 2. If Warrants are detachable from the Offered Securities only after the Detachable Date. W I T N E S S E T H : [WHEREAS, the Company has entered into an Indenture dated as of July 15, 1996 (the "Senior Indenture") between the Company and Citibank, N.A., as Trustee (the "Senior Indenture Trustee"), and an Indenture dated as of December 16, 1999 (the "Subordinated Indenture") between the Company and Chase Bank of Texas, National Association, as Trustee (the "Subordinated Indenture Trustee") (together, the "Trustees" or "Trustee" and "Indentures" or "Indenture"), providing for the issuance from time to time of its unsecured debt securities to be issued in one or more series as provided in the Indenture; and] WHEREAS, the Company proposes to sell [title of such securities being offered] (the "Offered Securities") with one or more warrants (the "Warrants") representing the right to purchase [title of such securities purchasable through exercise of Warrants] (the "Warrant Securities"), the Warrants to be evidenced by Warrant certificates issued pursuant to this Agreement (the "Warrant Certificates"); and WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company in connection with the issuance, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the - -------- 1 Complete or modify the provisions of this form as appropriate to reflect the terms of the Warrants and Warrant Securities. Monetary amounts may be in U.S. dollars in a foreign currency or in a composite currency, including but not limited to the euro.

terms and conditions on which they may be issued, transferred, exchanged, exercised and replaced; NOW, THEREFORE, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree as follows: ARTICLE 1 ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT CERTIFICATES SECTION 1.01. Issuance of Warrants. Issuance of Warrants. The Warrants shall be evidenced by one or more Warrant Certificates. Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein, to purchase [_____ shares of the Warrant Securities] [ aggregate principal amount of Warrant Securities ] and shall be initially issued in connection with the issuance of the Offered Securities [1: and shall be separately transferable immediately thereafter] [2: but shall not be separately transferable until on and after , (the "Detachable Date")]. The Warrants shall be initially issued [in units] with the Offered Securities, and each Warrant [included in such a unit] shall evidence the right, subject to the provisions contained herein and in the Warrant Certificates, to purchase [_____ shares of the Warrant Securities] [ aggregate principal amount of Warrant Securities] [included in such a unit]. SECTION 1.02. Execution and Delivery of Warrant Certificates. Each Warrant, whenever issued, shall be evidenced by a Warrant Certificate in registered form, substantially in the form set forth in Exhibit A hereto, shall be dated and may have such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by its chairman or vice chairman of the Board of Directors, the president, any managing director or the treasurer of the Company, in each case under its corporate seal, which may but need not be, attested by its Secretary or one of its Assistant Secretaries. Such signatures may be manual or facsimile signatures of such authorized officers and may be imprinted or otherwise reproduced on the Warrant Certificates. The corporate seal of the Company may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates. 2

No Warrant Certificate shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been countersigned by the Warrant Agent by manual signature. Such signature by the Warrant Agent upon any Warrant Certificate executed by the Company shall be conclusive evidence, and the only evidence, that the Warrant Certificate so countersigned has been duly issued hereunder. In case any officer of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent as provided herein, such Warrant Certificates may be countersigned and delivered notwithstanding that the person who signed such Warrant Certificates ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution of this Agreement any such person was not such officer. The term "Holder", when used with respect to any Warrant Certificate, shall mean any person in whose name at the time such Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose [2: or, prior to the Detachable Date, any person in whose name at the time the Offered Security to which such Warrant Certificate is attached is registered upon the register of the Offered Securities. Prior to the Detachable Date, the Company will, or will cause the registrar of the Offered Securities to, make available at all times to the Warrant Agent such information as to holders of the Offered Securities with Warrants as may be necessary to keep the Warrant Agent's records up to date.] SECTION 1.03. Issuance of Warrant Certificates. Warrant Certificates evidencing the right to purchase [_____ shares of the Warrant Securities] [an aggregate principal amount not exceeding aggregate principal amount of Warrant Securities] (except as provided in Sections 2.03, 3.02 and 4.01) may be executed by the Company and delivered to the Warrant Agent upon the execution of this Warrant Agreement or from time to time thereafter. The Warrant Agent shall, upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign Warrant Certificates evidencing ___________ Warrants representing the right to purchase up to [_____shares of the Warrant Securities] [ aggregate principal amount of Warrant Securities] and shall deliver such Warrant Certificates to or upon the order of the Company. Subsequent to such original issuance of the Warrant Certificates, the Warrant Agent shall countersign a Warrant Certificate only if the Warrant Certificate is issued in exchange or substitution for one or more previously countersigned Warrant Certificates or in 3

connection with their transfer as hereinafter provided or as provided in the antepenultimate paragraph of Section 2.03. Pending the preparation of definitive Warrant Certificates evidencing Warrants, the Company may execute and the Warrant Agent shall countersign and deliver temporary Warrant Certificates evidencing such Warrants (printed, lithographed, typewritten or otherwise produced, in each case in form satisfactory to the Warrant Agent). Such temporary Warrant Certificates shall be issuable substantially in the form of the definitive Warrant Certificates but with such omissions, insertions and variations as may be appropriate for temporary Warrant Certificates, all as may be determined by the Company with the concurrence of the Warrant Agent.

If a day on which Warrants may be exercised in the city in which such Warrants are to be exercised shall be a Saturday or Sunday or a day on which banking institutions in such city are authorized or required to be closed, then, notwithstanding any other provision of this Agreement or the Warrant Certificate evidencing such Warrants, but subject to the limitation that no Warrant may be exercised after the Expiration Date, the Warrants shall be exercisable on the next succeeding day which in such city is not a Saturday or Sunday or a day on which banking institutions in such city are authorized or required to be closed.

If fewer than all of the Warrants evidenced by such Warrant Certificate are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign and deliver, a new Warrant Certificate evidencing the number of such Warrants remaining unexercised. The Company shall not be required to pay any stamp or other tax or other governmental charge required to be paid in connection with any transfer involved in the issuance of the Warrant Securities, and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Security until such tax or other charge shall have been paid or it has been established to the Company's satisfaction that no such tax or other charge is due. 6

Upon the issuance of any new Warrant Certificate under this Section, the Company may require the payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant to this Section in lieu of any lost, mutilated, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement of lost, mutilated, stolen or destroyed Warrant Certificates.

Such successor or assuming corporation may thereupon cause to be signed, and may issue either in its own name or in the name of the Company, Warrant Certificates evidencing any or all of the Warrants issuable hereunder which theretofore shall not have been signed by the Company, and may execute and deliver Warrant Securities in its own name [,pursuant to the Indenture,] in fulfillment of its obligations to deliver Warrant Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same legal rank and benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Warrants had been issued at the date of the execution hereof. In any case of any such merger, consolidation, conveyance or transfer, such changes in phraseology and form (but not in substance) may be made in the Warrant Certificates representing the Warrants thereafter to be issued as may be appropriate. (b) The Warrant Agent may receive a written opinion of legal counsel (who shall be acceptable to the Warrant Agent) as conclusive evidence that any such merger, consolidation, conveyance or transfer complies with the provisions of this Section and the Indenture.

(d) Whenever any Warrant Certificates are so surrendered for exchange or registration of transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled thereto a Warrant Certificate or Warrant Certificates, duly authorized and executed by the Company, as so requested. The Warrant Agent shall not effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate evidencing a fraction of a Warrant or a number of full Warrants and a fraction of a Warrant (e) All Warrant Certificates issued upon any exchange or registration of transfer of Warrant Certificates shall be the valid obligations of the Company, evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for such exchange or registration or transfer.

To the Members of the Board of Directors:

As Senior Vice President, Secretary and General Counsel of Texas Instruments
Incorporated (the "Company"), I am familiar with a registration statement on
Form S-3 (the "Registration Statement") to be filed by the Company with the
Securities and Exchange Commission in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), of up to $1,000,000,000
aggregate principal amount of (i) senior debt securities and subordinated debt
securities (the "Debt Securities"); (ii) warrants to purchase Debt Securities or
other securities or rights (the "Warrants"); (iii) purchase contracts (the
"Purchase Contracts") requiring the holders thereof to purchase or sell (x) the
Company's securities or securities of an entity unaffiliated or affiliated with
the Company, a basket of such securities, an index or indices of such securities
or any combination of the above, (y) currencies or composite currencies, or (z)
commodities; (iv) units consisting of one or more of the foregoing securities
(the "Units"); which Debt Securities, Warrants, Purchase Contracts and Units may
be offered by the Company on a continuous or delayed basis pursuant to Rule 415
under the Act. The Debt Securities may be exchangeable for other Debt
Securities, Warrants, Purchase Contracts or Units, or other securities or
rights.

I have (directly or through attorneys acting under my direction) examined the
Registration Statement, the Indenture (the "Indenture") dated as of July 15,
1996 between the Company and Citibank, N.A., as trustee, the Subordinated
Indenture (the "Subordinated Indenture") dated as of December 16, 1999 between
the Company and Chase Bank of Texas, National Association, as trustee, forms of
warrant agreements and such records of the Company's corporate proceedings and
such other documents and have made such other factual and legal investigations
as I have deemed necessary or appropriate in order to render this opinion.
Further, I am familiar with additional corporate procedures that the Company
contemplates taking prior to the issuance of any Debt Securities, Warrants,
Purchase Contracts and Units.

Based upon such examinations and investigations and subject to (i) the proposed
additional proceedings being taken as are now contemplated prior to the issuance
of the Debt Securities, Warrants, Purchase Contracts and Units; (ii) the terms
of the Debt Securities, Warrants, Purchase Contracts and Units being otherwise
in compliance with then applicable law; (iii) the due execution of the warrant
agreements for attached warrants or bearer warrants; (iv) the effectiveness of
the Registration Statement under the Act and the qualification of the
Subordinated Indenture under the Trust Indenture Act of 1939, as amended; and
(v) the due execution, authentication and delivery of the Debt Securities,
Warrants, Purchase Contracts and Units, I am of the opinion that the Debt
Securities, Warrants, Purchase Contracts and Units will, upon the issuance and
sale thereof in the manner referred to in the Registration Statement, be legally
issued and valid and binding obligations of the Company.

I consent to the use of this opinion as an exhibit to the Registration Statement
and to the reference to my name under the caption "Legal Opinions" in the
Prospectus which is part of the Registration Statement. In giving such consent I
do not thereby admit that I come within the category of persons whose consent is
required under Section 7 of the Act or of the Rules and Regulations of the
Securities and Exchange Commission thereunder.

                                           Very truly yours,

Ladies and Gentlemen:

          We have acted as your counsel in connection with the Company's
Registration Statement on Form S-3 (the "Registration Statement") filed with
the Securities and Exchange Commission pursuant to the Securities Act of 1933,
as amended, for the registration of the sale by Texas Instruments Incorporated,
a Delaware corporation (the "Company") from time to time of up to
$1,000,000,000 aggregate principal amount of (i) senior debt securities and
subordinated debt securities (collectively, the "Debt Securities"), (ii)
warrants to purchase Debt Securities or other securities or rights
("Warrants"), (iii) purchase contracts ("Purchase Contracts") requiring the
holders thereof to purchase or sell (x) the Company's securities or securities
of an entity unaffiliated or affiliated with the Company, a basket of such
securities, an index or indices of such securities or any combination of the
above, (y) currencies or composite currencies or (z) commodities, (iv) units
("Units") consisting of Debt Securities, Warrants, Purchase Contracts or any
combination of the foregoing. The Debt Securities, Warrants, Purchase Contracts
and Units are herein collectively referred to as the "Securities". The Debt
Securities may be exchangeable for Securities or other securities or rights.
The senior Debt Securities are to be issued pursuant to an Indenture (the
"Senior Indenture") dated as of July 15, 1996 between the Company and Citibank,
N.A., as Trustee. The subordinated Debt Securities are to be issued pursuant to
an Indenture (the "Subordinated Indenture") dated as of December 16, 1999
between the Company and Chase Bank of Texas, National Association, as Trustee.
The Senior Indenture and the Subordinated Indenture are hereinafter referred to
individually as an "Indenture" and collectively as the "Indentures".

          We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments as we have deemed
necessary for the purposes of rendering this opinion.



Texas Instruments Incorporated -2- December 16, 1999 On the basis of the foregoing, we are of the opinion that: 1. When the Indentures have been duly authorized, executed and delivered by the Trustee and the Company, the specific terms of a particular Debt Security have been duly authorized and established in accordance with the applicable Indenture and such Debt Security has been duly authorized, executed, authenticated, issued and delivered in accordance with the applicable Indenture and the applicable underwriting or other agreement, such Debt Security will constitute a valid and binding obligation of the Company, enforceable in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other similar laws affecting creditors' rights generally from time to time in effect and to general equity principles). 2. When the Warrants have been duly authorized by the Company, the applicable Warrant Agreement has been duly executed and delivered and the Warrants have been duly issued and delivered by the Company as contemplated by the Registration Statement and any prospectus supplement relating thereto, the Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other similar laws affecting creditors' rights generally from time to time in effect and to general equity principles). 3. When the Units and Purchase Contracts have been duly authorized by the Company, the applicable Unit Agreement and Purchase Contract Agreement have been duly executed and delivered, the Units and Purchase Contracts will constitute valid and binding obligations of the Company, enforceable in accordance with their terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other similar laws affecting creditors' rights generally from time to time in effect and to general equity principles). In connection with the opinions expressed above, we have assumed that, at or prior to the time of the delivery of any such Security, (i) the Board of Directors shall have duly established the terms of such Security and duly authorized the issuance and sale of such Security and such authorization shall not have been modified or rescinded; (ii) the Registration Statement shall have been declared effective and such effectiveness

Texas Instruments Incorporated -3- December 16, 1999 shall not have been terminated or rescinded; and (iii) there shall not have occurred any change in law affecting the validity or enforceability of such Security. We have also assumed that none of the terms of any Security to be established subsequent to the date hereof, nor the issuance and delivery of such Security, nor the compliance by the Company with the terms of such Security will violate any applicable law or will result in a violation of any provision of any instrument or agreement then binding upon the Company, or any restriction imposed by any court or governmental body having jurisdiction over the Company. We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the federal laws of the United States of America. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In addition, we consent to the reference to us under the caption "Legal Matters" in the prospectus. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent. Very truly yours, /s/ Bruce Dallas ---------------------- Bruce Dallas

                        CONSENT OF INDEPENDENT AUDITORS
