WHEREAS the Board of Directors of each of the Company and Merger Sub has approved and declared advisable, and the Board of Directors of Parent has approved, this Agreement and the merger of Merger Sub with and into the Company (the "MERGER"), upon the terms and subject to the conditions set forth in this Agreement, whereby each issued and outstanding share of common stock, par value $0.10 per share, of the Company (the "COMPANY COMMON STOCK") not owned by Parent, Merger Sub or the Company, other than the Appraisal Shares (as defined below), will be converted into the right to receive $22.00 in cash, without interest (the "MERGER CONSIDERATION"); WHEREAS Parent, Merger Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe various conditions to the Merger; NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements set forth herein, the parties hereto agree as follows: ARTICLE I THE MERGER SECTION 1.01 THE MERGER. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the "DGCL"), Merger Sub shall be merged with and into the Company at the Effective Time (as defined below). At the Effective Time, the separate corporate existence of Merger <Page> 2 Sub shall cease and the Company shall continue as the surviving corporation (the "SURVIVING CORPORATION") and shall succeed to and assume all the rights and obligations of Merger Sub in accordance with the DGCL. SECTION 1.02. CLOSING. Upon the terms and subject to the conditions set forth in this Agreement, the closing of the Merger (the "CLOSING") shall take place at 11:00 a.m., New York time, on the second business day after the satisfaction or waiver of the conditions set forth in Section 6.01 (other than those that by their terms cannot be satisfied until the time of the Closing), at the offices of Cravath, Swaine & Moore, 825 Eighth Avenue, New York, New York 10019, or at such other time, date or place agreed to in writing by Parent and the Company; PROVIDED, HOWEVER, that if all the conditions set forth in Article VI shall not have been satisfied or waived on such second business day, then the Closing shall take place on the first business day on which all such conditions shall have been satisfied or waived. The date on which the Closing occurs is referred to in this Agreement as the "CLOSING DATE". SECTION 1.03. EFFECTIVE TIME. Upon the terms and subject to the conditions set forth in this Agreement, as soon as practicable on or after the Closing Date, a certificate of merger or other appropriate documents (in any such case, the "CERTIFICATE OF MERGER") shall be duly prepared and executed by the parties in accordance with the relevant provisions of the DGCL and filed with the Secretary of State of the State of Delaware. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such subsequent time or date as Parent and the Company shall agree and specify in the Certificate of Merger. The time at which the Merger becomes effective is referred to in this Agreement as the "EFFECTIVE Time". SECTION 1.04. EFFECTS OF THE MERGER. The Merger shall have the effects set forth in Section 259 of the DGCL. SECTION 1.05. CERTIFICATE OF INCORPORATION AND BY-LAWS. (a) The Restated Certificate of Incorporation of the Company shall be amended at the Effective Time to read in the form of Exhibit A and, as so amended, such Restated <Page> 3 Certificate of Incorporation shall be the Restated Certificate of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law. (b) The By-laws of Merger Sub as in effect immediately prior to the Effective Time shall be the By-laws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law. SECTION 1.06. DIRECTORS. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. SECTION 1.07. OFFICERS. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. ARTICLE II CONVERSION OF SECURITIES SECTION 2.01. CONVERSION OF CAPITAL STOCK. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of capital stock of the Company or Merger Sub: (a) CAPITAL STOCK OF MERGER SUB. Each issued and outstanding share of common stock of Merger Sub shall be converted into and become one fully paid and nonassessable share of common stock, par value $1.00 per share, of the Surviving Corporation. (b) CANCELATION OF TREASURY STOCK AND PARENT-OWNED STOCK. Each share of Company Common Stock that is owned by the Company as treasury stock, or by Parent or Merger Sub, immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to <Page> 4 exist and no consideration shall be delivered in exchange therefor. (c) CONVERSION OF COMPANY COMMON STOCK. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.01(b) and the Appraisal Shares) shall be converted into the right to receive the Merger Consideration. At the Effective Time all such shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such shares (a "CERTIFICATE") shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration with respect to each such share. (d) APPRAISAL RIGHTS. Notwithstanding anything in this Agreement to the contrary, shares (the "APPRAISAL SHARES") of Company Common Stock issued and outstanding immediately prior to the Effective Time that are held by any holder who is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL ("SECTION 262") shall not be converted into the right to receive the Merger Consideration as provided in Section 2.01(c), but instead such holder shall be entitled to payment of the fair value of such shares in accordance with the provisions of Section 262. At the Effective Time, all Appraisal Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such shares in accordance with the provisions of Section 262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to be paid the fair value of such holder's Appraisal Shares under Section 262 shall cease and each such Appraisal Share shall be deemed to have been converted at the Effective Time into, and each such Appraisal Share shall have become, the right to receive the Merger Consideration as provided <Page> 5 in Section 2.01(c). The Company shall provide prompt notice to Parent of any demands for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. SECTION 2.02. EXCHANGE OF CERTIFICATES. (a) PAYING AGENT. Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent for the payment of the Merger Consideration upon surrender of Certificates (the "PAYING AGENT"), and, from time to time after the Effective Time, Parent shall provide, or cause the Surviving Corporation to provide, to the Paying Agent funds in amounts and at the times necessary for the payment of the Merger Consideration pursuant to Section 2.01(c) upon surrender of Certificates, it being understood that any and all interest or income earned on funds made available to the Paying Agent pursuant to this Agreement shall be turned over to Parent (such funds being hereinafter referred to as the "EXCHANGE FUND"). (b) EXCHANGE PROCEDURE. As soon as reasonably practicable after the Effective Time, the Paying Agent shall mail to each holder of record of a Certificate (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such person shall pass, only upon proper delivery of the Certificates to the Paying Agent and shall be in customary form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of a Certificate in exchange for the Merger Consideration with respect to each share of Company Common Stock formerly represented by such Certificate. Upon surrender of a Certificate for cancelation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash <Page> 6 into which the shares formerly represented by such Certificate shall have been converted pursuant to Section 2.01(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock that is not registered in the stock transfer books of the Company, the proper amount of cash may be paid in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and 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 such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate. (c) NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. All cash paid upon the surrender of a Certificate in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificate. At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for transfer or any other reason, they shall be canceled and exchanged as provided in this Article II. (d) NO LIABILITY. None of Parent, Merger Sub, the Company or the Paying Agent shall be liable to any person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificates shall not have been surrendered prior to two years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration would otherwise escheat to or became the property of any Governmental Entity (as defined below)), any such Merger Consideration in respect thereof shall, to <Page> 7 the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto. (e) LOST CERTIFICATES. If any Certificate shall have been lost, stolen, defaced or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen, defaced or destroyed and, if required by Parent, the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against the Surviving Corporation with respect to such Certificate, the Paying Agent shall pay in respect of such lost, stolen, defaced or destroyed Certificate the Merger Consideration with respect to each share of Company Common Stock formerly represented by such Certificate. (f) WITHHOLDING RIGHTS. Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold any applicable taxes from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock. To the extent that amounts are so deducted and withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Paying Agent, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the stockholder in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Paying Agent. (g) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock for six months after the Effective Time shall be delivered to Parent, upon demand, and any holder of Company Common Stock who has not theretofore complied with this Article II shall thereafter look only to Parent for payment of its claim for Merger Consideration.

During the period from March 18, 2002 to the date of this Agreement, (x) there have been no issuances by the Company of shares of capital stock of, or other equity or voting interests in, the Company other than issuances of shares of Company Common Stock pursuant to the exercise of Company Stock Options outstanding on such date as required by their terms as in effect on the date of this Agreement and (y) there have been no issuances by the Company of options, warrants or other rights to acquire shares of capital stock or other equity or voting interests from the Company.

Each of the Company and its subsidiaries has timely paid or caused to be paid all taxes due with respect to the taxable periods covered by such tax returns and all other taxes otherwise due, and its most recent financial statements included in the Filed SEC Documents reflect an adequate reserve (including any reserve for deferred taxes) for all taxes not yet due but <Page> 26 that are payable for periods or portions thereof accrued through the date of such financial statements, except for such failures to pay or reserve that individually and in the aggregate have not had and could not reasonably be expected to have a Material Adverse Effect.

Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative or affiliate of the Company or any of its subsidiaries, whether or not such person is purporting to act on behalf of the Company <Page> 39 or any of its subsidiaries or otherwise, shall be deemed to be a breach of this Section 4.02(a) by the Company.

The term "TAKEOVER PROPOSAL" means any inquiry, proposal or offer from any person (other than Parent) relating to, or that is reasonably likely to lead to, any direct or indirect acquisition, in one transaction or a series of transactions, including by way of any merger, consolidation, tender offer, exchange offer, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture or similar transaction, of (A) assets or businesses that constitute or represent 15% or more of the revenues, income from continuing operations, net income or total assets of the Company and its subsidiaries, taken as a whole, or (B) 15% or more of the outstanding shares of Company Common Stock or capital stock of, or other equity or voting interests in, any of the Company's subsidiaries directly or indirectly holding the assets or businesses referred to in clause (A) above. (b) Neither the Board of Directors of the Company nor any committee thereof shall (i) withdraw (or modify in a manner adverse to Parent or Merger Sub) or propose publicly to withdraw (or modify in a manner adverse to Parent or Merger Sub) the recommendation or declaration of advisability by such Board of Directors of the Company or any such committee of this Agreement or the Merger, or recommend, or propose publicly to recommend, the approval or adoption of any Takeover Proposal (each such action being referred to herein as an "ADVERSE RECOMMENDATION"), unless the Board of Directors of the Company determines in good faith, based on such matters as it deems appropriate, after consulting with legal counsel, that the failure to take such action would be reasonably likely to result in a breach of its fiduciary duties under applicable law, (ii) adopt or approve, or propose publicly to adopt or approve, any Takeover Proposal, or withdraw its approval of <Page> 40 the Merger, or propose publicly to withdraw its approval of the Merger, (iii) cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement (each, an "ACQUISITION AGREEMENT") constituting or related to, or which is intended to or is reasonably likely to lead to, any Takeover Proposal (other than a confidentiality agreement referred to in Section 4.02(a)) or (iv) agree or resolve to take any of the actions prohibited by clauses (i), (ii) or (iii) of this sentence. Notwithstanding anything in this Section 4.02 to the contrary, at any time prior to obtaining the Company Stockholder Approval, the Board of Directors of the Company may, in response to a Superior Proposal (as defined below) that did not result from a breach of Section 4.02(a), cause the Company to terminate this Agreement pursuant to Section 7.01(f) and concurrently enter into an Acquisition Agreement; PROVIDED, HOWEVER, that the Company shall not terminate this Agreement pursuant to Section 7.01(f), and any purported termination pursuant to Section 7.01(f) shall be void and of no force or effect, unless the Company shall have complied with all the provisions of this Section 4.02, including the notification provisions in this Section 4.02, and with all applicable requirements of Sections 5.06(b) (including the payment of the Termination Fee (as defined below) prior to or concurrently with such termination); and PROVIDED FURTHER, HOWEVER, that the Company shall not exercise its right to terminate this Agreement pursuant to Section 7.01(f) until after the fifth business day following Parent's receipt of written notice (a "NOTICE OF SUPERIOR PROPOSAL") from the Company advising Parent that the Board of Directors of the Company has received a Superior Proposal, specifying the material terms and conditions of the Superior Proposal, identifying the person making such Superior Proposal and stating that the Board of Directors of the Company intends to exercise its right to terminate this Agreement pursuant to Section 7.01(f) (it being understood and agreed that, prior to any such termination taking effect, any amendment to the price or any other material term of a Superior Proposal shall require a new Notice of Superior Proposal and a new five business day period). <Page> 41 The term "SUPERIOR PROPOSAL" means any bona fide binding offer made by a third party in respect of a transaction that if consummated would result in such third party (or in the case of a direct merger between such third party and the Company or one of its subsidiaries, the stockholders of such third party) acquiring, directly or indirectly, all or substantially all of the voting power of the Company Common Stock or all or substantially all the assets of the Company and its subsidiaries, taken as a whole, which transaction the Board of Directors of the Company determines in its good faith judgment (after consultation with a financial advisor of nationally recognized reputation) (taking into account the person making the offer, the consideration offered, the likelihood of consummation (including the legal, financial and regulatory aspects of the offer) as well as any other factors deemed relevant by the Board of Directors of the Company) to be more favorable from a financial point of view to the stockholders of the Company than the Merger, taking into account any changes to the terms of this Agreement offered by Parent in response to such Superior Proposal or otherwise. (c) In addition to the obligations of the Company set forth in paragraphs (a) and (b) of this Section 4.02, the Company promptly shall advise Parent orally and in writing of any request for information that the Company reasonably believes could lead to or contemplates a Takeover Proposal or of any Takeover Proposal, or any inquiry the Company reasonably believes could lead to any Takeover Proposal, the material terms and conditions of such request, Takeover Proposal or inquiry (including any subsequent amendment or other modification to such terms and conditions) and the identity of the person making any such request, Takeover Proposal or inquiry. The Company shall keep Parent informed in all material respects of the status and details (including material amendments or proposed amendments) of any such request, Takeover Proposal or inquiry. (d) Nothing contained in this Section 4.02 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or (ii) making any disclosure to the Company's stockholders if, in the good faith judgment of the Board of <Page> 42 Directors of the Company, after consultation with outside counsel, failure to make such disclosure would be inconsistent with applicable law; PROVIDED, HOWEVER, that in no event shall the Company or its Board of Directors or any committee thereof take, or agree or resolve to take, any action prohibited by Section 4.02(b)(i) or 4.02(b)(ii). Notwithstanding anything in this Section 4.02(d) or the second sentence of Section 4.02(b), but subject always to Section 7.01(f), the Company Board may not take any action that would result in the Company's stockholders no longer being legally capable under the DGCL of validly adopting this Agreement.

Each Indemnified Party shall be entitled to the advancement of expenses to the full extent contemplated in this Section 5.05(a) in connection with any such action; PROVIDED, HOWEVER, that any person to whom expenses are advanced provides an undertaking to repay such advances if <Page> 48 it is ultimately determined that such person is not entitled to indemnification.

(c) For six years after the Effective Time, unless Parent agrees in writing to guarantee the indemnification obligations set forth in Section 5.05(b), Parent shall cause to be maintained in effect the Company's current directors' and officers' liability insurance covering each person currently covered by the Company's directors' and officers' liability insurance policy for acts or omissions occurring prior to the Effective Time on terms with respect to such coverage and amounts no less favorable in any material respect to such directors and officers than those of such policy as in effect on the date of this Agreement; PROVIDED that Parent may substitute therefor policies of a reputable insurance company the material terms of which, including coverage and amount, are no less favorable in any material respect to such directors and officers than the insurance coverage otherwise required under this Section 5.05(c); PROVIDED, HOWEVER, that in no event shall Parent be required to pay aggregate annual premiums for insurance under this Section 5.05(c) in excess of $632,952 (the "MAXIMUM PREMIUM"), which the Company represents and warrants is equal to 200% of the annual premiums paid as of the date hereof by the Company for such insurance; PROVIDED that, if such premium exceeds the Maximum Premium, Parent shall nevertheless be obligated to provide the most advantageous coverage as may be obtained for such Maximum Premium. <Page> 49 (d) If Parent or the Surviving Corporation or any of their successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then and in either such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations of Parent or the Surviving Corporation, as applicable, set forth in this Section 5.05. (e) The rights of each Indemnified Party hereunder shall be in addition to any other rights such Indemnified Party may have under applicable law, agreement or otherwise. The provisions of this Section 5.05 shall survive the consummation of the Merger and expressly are intended to benefit each of the Indemnified Parties, their heirs and representatives. SECTION 5.06. FEES AND EXPENSES. (a) All fees and expenses incurred in connection with this Agreement, the Merger and the other transactions contemplated hereby shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated, except that Parent and the Company shall share equally all fees and expenses incident to the filing and distribution of the Proxy Statement (including all SEC and other filing fees and all printing and mailing expenses associated with the Proxy Statement) and all fees and expenses incident to filings under the HSR Act and other applicable antitrust laws (including all fees and expenses of experts). (b) In the event that (i) (A) a Takeover Proposal shall have been made to the Company or its stockholders or any person has announced an intention (whether or not conditional and whether or not withdrawn) to make a Takeover Proposal, (B) thereafter this Agreement is terminated by either Parent or the Company pursuant to 7.01(b)(iii) or 7.01(d) and (C) within 15 months after such termination, the Company or any of its subsidiaries enters into any Acquisition Agreement with respect to, or consummates, any Takeover Proposal (solely for purposes of this Section 5.06(b)(i)(C), the term "Takeover Proposal" shall have the meaning set forth in the definition of <Page> 50 Takeover Proposal contained in Section 4.02(a) except that all references to 15% shall be deemed references to 50%), (ii) this Agreement is terminated by the Company pursuant to Section 7.01(f) or (iii) this Agreement is terminated by Parent pursuant to Section 7.01(c), then the Company shall pay Parent a fee equal to $65 million (the "TERMINATION FEE") by wire transfer of same day funds to an account designated by Parent (x) in the case of a termination by the Company pursuant to Section 7.01(f), concurrently with such termination, (y) in the case of a termination by Parent pursuant to Section 7.01(c), within two business days after such termination and (z) in the case of a payment as a result of any event referred to in Section 5.06(b)(i)(C), upon the first to occur of such events. The Company acknowledges that the agreements contained in Section 5.06(b) are an integral part of the transactions contemplated hereby, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails promptly to pay the amounts due pursuant to Section 5.06(b) and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company, the Company shall pay to Parent interest on the amount set forth in Section 5.06(b) from and including the date payment of such amount was due to but excluding the date of actual payment at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made, together with reasonable legal fees and expenses incurred in connection with such suit.

If a majority in number representing three fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of this corporation as consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of this corporation, as the case may be, and also on this corporation.
