RECITALS WHEREAS, the Boards of Directors of Purchaser and the Company each have determined that it is in the best interests of their respective shareholders for Purchaser to acquire the Company upon the terms and subject to the conditions set forth herein; and WHEREAS, the Company, Purchaser and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with this Agreement. NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein the parties hereto hereby agree as follows: ARTICLE I The Tender Offer 1.1. Tender Offer. (a) Provided that this Agreement shall not have been terminated in accordance with Article IX hereof and none of the events set forth in Annex A hereto shall have occurred or be existing, within five business days of the date hereof, Merger Sub will commence a tender offer (the "Offer") for all of the outstanding common stock, par value $0.01 per share (the "Shares"), of the Company at a price of $20.50 per Share in cash, net to the seller. The obligation of Merger Sub to accept for payment and pay for Shares tendered pursuant to the Offer shall be subject only to the satisfaction or waiver of the conditions to the Offer set forth in Annex A hereto. Without the prior written consent of the Company, Merger Sub shall not (i) change or waive the Minimum Condition (as defined in Annex A), (ii) reduce the number of 2 Shares subject to the Offer, (iii) reduce the price per Share to be paid pursuant to the Offer, (iv) extend the Offer if all of the conditions to the Offer are satisfied or waived, (v) change the form of consideration payable in the Offer, or (vi) amend, modify, or add to the conditions of the Offer in any manner adverse to the holders of Shares. So long as this Agreement is in effect and the conditions to the Offer have not been satisfied or waived, at the request of the Company, Merger Sub shall extend the Offer for an aggregate period of not more than 10 business days beyond the originally scheduled expiration date of the Offer. Subject to the terms and conditions of the Offer, Purchaser will promptly pay for all Shares tendered and not withdrawn pursuant to the Offer as soon as practicable after the expiration of the Offer. The Company's Board of Directors shall recommend acceptance of the Offer to its stockholders in a Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D- 9") to be filed with the Securities and Exchange Commission (the "SEC") upon commencement of the Offer; provided, however, that if the Company's Board of Directors determines consistent with its fiduciary duties to amend or withdraw its recommendation, such amendment or withdrawal shall not constitute a breach of this Agreement. (b) Purchaser agrees, as to the Offer to Purchase and related Letter of Transmittal (which together constitute the "Offer Documents") and the Company agrees, as to the Schedule 14D-9, that such documents shall, in all material respects, comply with the requirements of the Exchange Act and the rules and regulations thereunder and other applicable laws. The Company and its counsel, as to the Offer Documents, and Merger Sub and its counsel, as to the Schedule 14D-9, shall be given an opportunity to review such documents prior to their being filed with the SEC. (c) In connection with the Offer, the Company will cause its Transfer Agent to furnish promptly to Merger Sub a list, as of a recent date, of the record holders of Shares and their addresses, as well as mailing labels containing the names and addresses of all record holders of Shares and lists of security positions of Shares held in stock deposito- ries. The Company will furnish Merger Sub with such additional information (including, but not limited to, updated lists of holders of Shares and their addresses, mailing labels and lists of security positions) and such other assistance as Purchaser or Merger Sub or their agents may reasonably request in communicating the Offer to the record and beneficial holders of Shares. All such information shall be held subject to the letter agreement, dated July 26, 1996 (the "Confidentiality Agreement"), 3 between Purchaser and the Company relating to confidential information. ARTICLE II The Merger; Closing; Effective Time 2.1. The Merger. Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 2.3) Merger Sub shall be merged with and into the Company and the separate corporate existence of Merger Sub shall thereupon cease (the "Merger"). The Company shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the "Surviving Corporation") and shall continue to be governed by the laws of the State of Delaware, and the separate corporate existence of the Company with all its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger, except as set forth in Section 3.1. The Merger shall have the effects specified in the Delaware General Corporation Law (the "DGCL"). 2.2. Closing. The closing of the Merger (the "Closing") shall take place (i) at the offices of Sullivan & Cromwell, 125 Broad Street, New York, New York at 10:00 A.M. on the first business day on which the last to be fulfilled or waived of the conditions set forth in Article VIII hereof shall be fulfilled or waived in accordance with this Agreement or (ii) at such other place and time and/or on such other date as the Company and Purchaser may agree. 2.3. Effective Time. As soon as practicable following the Closing, and provided that this Agreement has not been terminated or abandoned pursuant to Article IX hereof, the Company and the Purchaser will cause a Certificate of Merger (the "Delaware Certificate of Merger") to be executed and filed with the Secretary of State of Delaware as provided in Section 251 of the DGCL. The Merger shall become effective on the date on which the Delaware Certificate of Merger has been duly filed with the Secretary of State of Delaware, and such time is hereinafter referred to as the "Effective Time." 4 ARTICLE III Certificate of Incorporation and By-Laws of the Surviving Corporation 3.1. The Certificate of Incorporation. The Restated Certificate of Incorporation of the Company (the "Certificate") in effect at the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation, until duly amended in accordance with the terms thereof, and the DGCL, except that Article Fourth of the Company's Certificate shall be amended to read in its entirety as follows: "The aggregate number of shares which the Corporation shall have the authority to issue is 1,000 shares of Common Stock, par value $0.01 per share." 3.2. The By-Laws. The By-Laws of Merger Sub in effect at the Effective Time shall be the By-Laws of the Surviving Corporation, until duly amended in accordance with the terms thereof and the DGCL. ARTICLE IV Officers and Directors of the Surviving Corporation 4.1. Officers and Directors. The directors of Merger Sub and the officers of the Company at the Effective Time shall, from and after the Effective Time, be the directors and officers, respectively, of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Surviving Corporation's Certificate of Incorporation and By-Laws. 4.2. Actions by Directors. Following the election or appointment of Purchaser's designees pursuant to Section 4.3 hereof, and prior to the Effective Time, the approval of a majority of the directors of the Company then in office who were not designated by Purchaser shall be required to authorize (and such authorization shall constitute the authorization of the Board of Directors of the Company and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) any termination of this Agreement by the Company, any amendment of this Agreement requiring action by the Board of Directors of the Company, 5 any extension of time for the performance of any of the obligations or other acts of Purchaser or Merger Sub, any waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company or any other rights of the Company hereunder, and any amendment or withdrawal by the Board of Directors of its recommendation of the Merger pursuant to Section 7.3 hereof. 4.3. Boards of Directors; Committees. (a) If requested by Purchaser, the Company will, subject to compliance with applicable law and immediately following the purchase by Merger Sub of more than 50 percent of the outstanding Shares pursuant to the Offer, take all actions necessary to cause persons designated by Purchaser to become directors of the Company so that the total number of such persons equals that number of directors, rounded up to the next whole number, which represents the product of (x) the total number of directors on the Board of Directors multiplied by (y) the percentage that the number of Shares so purchased plus any Shares beneficially owned by Purchaser or its affiliates on the date hereof bears to the number of Shares outstanding at the time of such purchase; provided, however, that in no event shall Purchaser be entitled to designate a majority of the Board of Directors unless it is the beneficial owner of Shares entitling it to exercise at least a majority of the voting power of the Company's outstanding shares entitled to vote generally in the election of directors. In furtherance thereof, the Company will use its reasonable best efforts to secure the resignation of all but three directors, or will increase the size of the Board, or both, as is necessary to permit Purchaser's designees to be elected to the Company's Board of Directors; provided, however, that prior to the Effective Time, the Company's Board of Directors shall always have at least three members who are neither officers of Purchaser nor designees, shareholders or affiliates of Purchaser ("Purchaser Insiders"). At such time, the Company, if so requested, will use its reasonable efforts to cause persons designated by Purchaser to constitute the same percentage of each committee of such board, each board of directors of each subsidiary of the Company and each committee of each such board (in each case to the extent of the Company's ability to elect such persons). The Company's obligations to appoint designees to the Board of Directors shall be subject to Section 14(f) of the Securities Exchange Act of 1934 (the "Exchange Act") and Rule 14f-1 thereunder. The Company shall promptly take all actions required in order to fulfill its obliga- tions under this Section 4.3 and shall include in the Schedule 14D-9 such information as is required under such Section and Schedule. The Purchaser will supply to the Company in writing and be solely respon- 6 sible for any information with respect to the Purchaser and its subsidiaries (collectively, the "Purchaser Companies") and the nominees, directors and affiliates thereof required by Section 14(f) and Rule 14f-1 to be included in the Schedule 14D-9. ARTICLE V Conversion or Cancellation of Shares in the Merger 5.1. Conversion or Cancellation of Shares. The manner of converting or canceling shares of the Company and Merger Sub in the Merger shall be as follows: (a) At the Effective Time, each Share issued and outstanding immediately prior to the Effective Time (other than Shares owned by Purchaser, Merger Sub or any other subsidiary of Purchaser (collectively, the "Purchaser Companies") or Shares which are held by stockholders ("Dissenting Stockholders") exercising appraisal rights pursuant to Section 262 of the DGCL) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive, without interest, an amount in cash equal to $20.50 or such greater amount which may be paid pursuant to the Offer (the "Merger Consideration"). All such Shares, by virtue of the Merger and without any action on the part of the holders thereof, shall no longer be outstanding and shall be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such Shares shall thereafter cease to have any rights with respect to such Shares, except the right to receive the Merger Consideration for such Shares upon the surrender of such certificate in accordance with Section 5.2 or the right, if any, to receive payment from the Surviving Corporation of the "fair value" of such Shares as determined in accordance with Section 262 of the DGCL. (b) At the Effective Time, each Share issued and outstanding at the Effective Time and owned by any of the Purchaser Companies, and each Share issued and held in the Company's treasury at the Effective Time, shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be canceled and retired without payment of any consideration therefor and shall cease to exist. (c) At the Effective Time, each share of Common Stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall, 7 by virtue of the Merger and without any action on the part of Merger Sub or the holders of such shares, be converted into one Share. 5.2. Payment for Shares. Purchaser shall make available or cause to be made available to the paying agent appointed by Purchaser with the Company's prior approval (the "Paying Agent") amounts sufficient in the aggregate to provide all funds necessary for the Paying Agent to make payments pursuant to Section 5.1(a) hereof to holders of Shares issued and outstanding immediately prior to the Effective Time. Promptly after the Effective Time, the Purchaser shall instruct the Paying Agent to mail to each person who was, at the Effective Time, a holder of record (other than any of the Purchaser Companies) of issued and outstanding Shares a form (mutually agreed to by Purchaser and the Company) of letter of transmittal and instructions for use in effecting the surrender of the certificates which, immediately prior to the Effective Time, represented any of such Shares in exchange for payment therefor. Upon surrender to the Paying Agent of such certificates, together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the Surviving Corporation shall promptly cause to be paid to the persons entitled thereto a check in the amount to which such persons are entitled, after giving effect to any required tax withholdings. No interest will be paid or will accrue on the amount payable upon the surrender of any such certificate. If payment is to be made to a person other than the registered holder of the certificate surrendered, it shall be a condition of such payment that the certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer and that the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of the certificate surrendered or establish to the satisfaction of the Surviving Corporation or the Paying Agent that such tax has been paid or is not applicable. One hundred and eighty days following the Effective Time, the Surviving Corporation shall be entitled to cause the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent which have not been disbursed to holders of certificates formerly representing Shares outstanding on the Effective Time, and thereafter such holders shall be entitled to look to the Surviving Corporation only as general creditors thereof with respect to the cash payable upon due surrender of their certificates. Notwithstanding the foregoing, neither the Paying Agent nor any party hereto shall be liable to any holder of certificates formerly representing Shares for any amount paid to a public official 8 pursuant to any applicable abandoned property, escheat or similar law. The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, in connection with the exchange of cash for Shares and Purchaser shall reimburse the Surviving Corporation for such charges and expenses. 5.3. Dissenters' Rights. If any Dissenting Stockholder shall be entitled to be paid the "fair value" of his or her Shares, as provided in Section 262 of the DGCL, the Company shall give Purchaser notice thereof and Purchaser shall have the right to participate in all negotiations and proceedings with respect to any such demands. Neither the Company nor the Surviving Corporation shall, except with the prior written consent of Purchaser, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment. If any Dissenting Stockholder shall fail to perfect or shall have effectively withdrawn or lost the right to dissent, the Shares held by such Dissenting Stockholder shall thereupon be treated as though such Shares had been converted into the Merger Consideration pursuant to Section 5.1. 5.4. Transfer of Shares After the Effective Time. No transfers of Shares shall be made on the stock transfer books of the Surviving Corporation at or after the Effective Time.
