Each of the foregoing persons is a citizen of the United States. The business address of each of the foregoing persons is c/o Parent, 13500 North Central Expressway, P.O. Box 655474, Dallas, Texas 75265-5474. 5 6 During the past five years, neither Parent nor Purchaser and, to the best knowledge of Parent and Purchaser, no other person referenced in this Item 2 has been convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The funds used by Purchaser to purchase the shares of Common Stock beneficially owned directly by Purchaser (and indirectly by Parent) were obtained through a capital contribution from Parent. Parent obtained such funds from its cash on hand. ITEM 4. PURPOSE OF TRANSACTION Parent, Purchaser and the Company are parties to an Agreement and Plan of Merger dated as of November 19, 1997 (the "Merger Agreement"). Pursuant to the Merger Agreement, Purchaser commenced on November 25, 1997 a tender offer (the "Offer") for all outstanding shares of Common Stock of the Company at a price of $20.00 per share, net to the seller in cash, without interest. The Offer expired at 12:00 midnight, New York City time, on December 23, 1997. Following the expiration of the Offer, Purchaser accepted for payment 15,290,381 shares of Common Stock (approximately 77.3% of the issued and outstanding shares of Common Stock) validly tendered and not withdrawn pursuant to the Offer, which number gives effect to the failure of a number of shares of Common Stock to be delivered in accordance with guaranteed delivery procedures. In accordance with the terms of the Merger Agreement, three of the Company's five directors resigned upon the consummation of the Offer and were replaced with three persons designated by Parent. Pursuant to the Merger Agreement, a meeting of the Company's stockholders will be held as soon as practicable for the purpose of approving the merger (the "Merger") of Purchaser with and into the Company. In connection with the Merger, the Company will become a wholly owned subsidiary of Parent and each issued and outstanding share of the Company's Common Stock (other than shares owned by Purchaser, held in the treasury of the Company or with respect to which dissenter's rights have been demanded and perfected in accordance with applicable Delaware law) shall be converted into the right to receive $20.00 in cash. Under Delaware law, the affirmative vote of holders of a majority of the outstanding shares of Common Stock entitled to vote, including the shares owned by Purchaser, will be required to approve the Merger. Because Purchaser owns approximately 77.3% of the shares of Common Stock entitled to vote, it will have the power to effect the Merger without the approval of any other stockholder of Company. Upon consummation of the Merger, Parent intends to delist the Company's Common Stock from the NASDAQ Stock Market and to terminate the registration of the same under Section 12 of the Exchange Act. 6 7 The purpose of the Offer and the Merger is to enable Parent, through Purchaser, to acquire control of the Company's board of directors and the entire equity interest in the Company. The Offer was commenced and consummated to increase the likelihood that the Merger would be completed promptly. Except for the Merger and the election of Parent's designees to fill a majority of the seats on the Company's board of directors, Parent and Purchaser have no present plans or proposal that would result in an extraordinary corporate transaction, such as a merger, reorganization, liquidation, or sale or transfer of a material amount of assets, involving the Company or any other material changes in the Company's capitalization, dividend policy, corporate structure, business or composition of its management. However, Parent and Westell Technologies, Inc. ("Westell") have entered into an agreement in principle to outsource to Westell certain of the Company's manufacturing activities so that following the Merger, the Company can focus on the commercial implementation of its technologies and research and development activities related thereto. Notwithstanding the foregoing, Parent intends to evaluate and review from time to time the Company's assets, operations, management and personnel and consider what, if any, changes would be desirable in light of circumstances which then exist. Parent reserves the right to take such actions or effect such changes as it deems advisable. ITEM 5. INTEREST OF SECURITIES OF ISSUER Purchaser is the direct beneficial owner, and Parent is the indirect beneficial owner, of 15,290,381 shares of the Company's Common Stock (approximately 77.3% of the issued and outstanding shares). All of such shares were purchased pursuant to the Offer as described in Item 4. Parent and Purchaser may be deemed to share both the power to vote and the power to dispose of all shares of the Company's Common Stock held by Purchaser. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Reference is hereby made to the information provided under Item 4 of this statement, which Item contains the information called for in response to this Item 6. 7 8 ITEM 7.
