RECITALS -------- WHEREAS, the Boards of Directors of each of Parent, Merger Sub and the Company have determined that the merger of Merger Sub with and into the Company (the "Merger") in accordance with the provisions of the Delaware General Corporation Law, as amended (the "DGCL"), and subject to the terms and conditions of this Agreement, is advisable and in the best interests of Parent, Merger Sub and the Company and their respective stockholders. NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto intending to be legally bound do hereby agree as follows: ARTICLE I THE MERGER SECTION 1.1. GENERAL. ------- (a) Subject to the terms and conditions of this Agreement and in accordance with the DGCL, at the Effective Time (i) Merger Sub shall be merged with and into the Company, (ii) the separate corporate existence of Merger Sub shall cease and (iii) the Company shall be the surviving company (the "Surviving Company") and shall continue its legal existence under the laws of the State of Delaware. (b) The Merger shall become effective at the time of filing of a Certificate of Merger with the Secretary of State of the State of Delaware in accordance with the provisions of Section 251 of the DGCL, or at such later time as may be stated in the Certificate of Merger (the "Effective Time"). (c) The closing of the Merger (the "Closing") shall take place at the offices of Hogan & Hartson, L.L.P., 111 S. Calvert Street, Baltimore, Maryland 21202 at 10:00 A.M., subject to the satisfaction or waiver of the conditions set forth in ARTICLE VI, two Business Days after the date on which the last of the conditions set forth in SECTIONS 6.1(a) and 6.1(b) shall have been satisfied or waived, or on such other date, time and place as the Company, Parent and Merger Sub may mutually agree (the "Closing Date"). (d) At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of Merger Sub shall vest in the Surviving Company, and all debts, liabilities, obligations, and duties of Merger Sub shall become the debts, liabilities, obligations, restrictions, disabilities and duties of the Surviving Company. SECTION 1.2. CERTIFICATE OF INCORPORATION. ---------------------------- The Certificate of Incorporation of the Company, as in effect immediately prior to the Effective Time, shall be amended so that Article FOURTH of the Certificate of Incorporation shall be amended to read in its entirety as follows: "The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is 100 shares of Common Stock par value $.01 per share." As so amended, the Certificate of Incorporation of the Company shall be the Certificate of Incorporation of the Surviving Company, until thereafter changed or amended as provided therein and by applicable law. SECTION 1.3. THE BY-LAWS. ----------- The By-laws of Merger Sub, as in effect immediately prior to the Effective Time, shall be adopted as the By-laws of the Surviving Company, until thereafter changed or amended as provided therein and by applicable law. SECTION 1.4. BOARD OF DIRECTORS AND OFFICERS. ------------------------------- From and after the Effective Time, the Board of Directors and Officers of Merger Sub at the Effective Time shall continue as the Board of Directors and Officers of the Surviving Company, each to hold office in accordance with the certificate of incorporation and by-laws of the Surviving Company until his or her respective successors are duly elected or appointed and qualified. SECTION 1.5. CONVERSION OF SECURITIES. ------------------------ At the Effective Time, by virtue of the Merger and without any action on the part of the Company or the holders of the Company's common stock, par value $0.01 per share (the "Company Common Stock"): (a) Each issued and outstanding share of Merger Sub capital stock immediately prior to the Effective Time shall be converted into one validly issued, fully paid and non-assessable share of Common Stock of the Surviving Company; (b) Each share of Company Common Stock held in the treasury of the Company and each share of Company Common Stock owned by Merger Sub or Parent shall be cancelled without any conversion thereof and no payment or distribution shall be made with respect thereto; and (c) At the Effective Time, each then issued and outstanding share of Company Common Stock together with associated Company Rights (as defined in SECTION 2.3) (other than shares to be cancelled in accordance with SECTION 1.5(b)) shall be converted into, and become exchangeable for the right to receive consideration consisting of $47.50 in cash (the "Merger Consideration"). SECTION 1.6. ADJUSTMENTS TO PREVENT DILUTION. ------------------------------- In the event that, prior to the Effective Date, any stock split, combination, reclassification or stock dividend with respect to the Company Common Stock, any change or conversion of Company Common Stock into other securities or any other dividend or distribution with respect to the Company Common Stock should occur or, if a record date with respect to any of the foregoing should occur, appropriate and proportionate adjustments shall be made to the Merger Consideration, and thereafter all references to the Merger Consideration shall be deemed to be to such Merger Consideration as so adjusted. SECTION 1.7. EXCHANGE PROCEDURES; DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES; STOCK TRANSFER BOOKS. -------------------------------------------------- (a) Prior to the Effective Time, Parent shall appoint a commercial bank or trust company reasonably acceptable to the Company to act as exchange agent for the purpose of exchanging Certificates for the Merger Consideration (the "Exchange Agent"). At or prior to the Effective Time, Parent shall deposit with the Exchange Agent for the benefit of the holders of shares of Company Common Stock the aggregate Merger Consideration (such cash is referred to herein as the "Exchange Fund"). (b) As soon as practicable after the Effective Time, Parent shall cause the Exchange Agent to send to each Person who was, at the Effective Time, a holder of record of certificates which represented outstanding Company Common Stock (the "Certificates") which shares were converted into the right to receive the Merger Consideration pursuant to SECTION 1.5, a letter of transmittal which (i) shall specify that delivery shall be effected and risk of loss and title to such Certificates shall pass, only upon actual delivery thereof to the Exchange Agent and (ii) shall contain instructions for use in effecting the surrender of the Certificates. Upon surrender to the Exchange Agent of Certificates for cancellation, together with such letter of transmittal duly executed, such holder shall be entitled to receive in exchange therefor the Merger Consideration, and the Certificates so surrendered shall then be cancelled. Subject to SECTION 1.7(c) and SECTION 1.8, until surrendered as contemplated by this SECTION 1.7(b), each Certificate, from and after the Effective Time, shall be deemed to represent only the right to receive, upon such surrender, the Merger Consideration. (c) If the Merger Consideration is to be paid to any Person other than the registered holder of the Certificate surrendered in exchange therefor, it shall be a condition to such exchange that such surrendered Certificate shall be properly endorsed and otherwise in proper form for transfer and such Person either (i) shall pay to the Exchange Agent any transfer or other taxes required as a result of the distribution of such cash payment to such Person or (ii) shall establish to the reasonable satisfaction of the Exchange Agent that such tax has been paid or is not applicable. Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent or the Exchange Agent. All amounts in respect of taxes received or withheld by Parent shall be disposed of by Parent in accordance with the Code or such state, local or foreign tax law, as applicable. (d) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and subject to such other reasonable conditions as the Board of Directors of Parent may impose, Parent shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration as determined under SECTION 1.5(c) in respect of such Certificate. (e) 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 thereafter there shall be no further registration of transfers of shares of Company Common Stock on the records of the Company. From and after the Effective Time, the holders of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares except as otherwise provided herein or by applicable law. SECTION 1.8. RETURN OF EXCHANGE FUND. ----------------------- Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for six months after the Effective Date shall be delivered to Parent, upon its request, and any such former holders who have not theretofore surrendered to the Exchange Agent their Certificates in compliance herewith shall thereafter look only to Parent for payment of the Merger Consideration SECTION 1.9. NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. --------------------------------------------------- The Merger Consideration delivered upon the surrender for exchange of any Certificate in accordance with the terms hereof shall be deemed to have been delivered (and paid) in full satisfaction of all rights pertaining to the Company Common Stock previously represented by such Certificate. SECTION 1.10. FURTHER ASSURANCES. ------------------ If at any time after the Effective Time the Surviving Company shall consider or be advised that any deeds, bills of sale, assignments or assurances or any other acts or things are necessary, desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in the Surviving Company, its right, title or interest in, to or under any of the rights, privileges, powers, franchises, properties or Assets of either the Company or Merger Sub or (b) otherwise to carry out the purposes of this Agreement, the Surviving Company and its proper officers and directors or their designees shall be authorized to execute and deliver, in the name and on behalf of the Company or Merger Sub, all such deeds, bills of sale, assignments and assurances and do, in the name and on behalf of the Company or Merger Sub, all such other acts and things necessary, desirable or proper to vest, perfect or confirm its right, title or interest in, to or under any of the rights, privileges, powers, franchises, properties or Assets of the Company or Merger Sub and otherwise to carry out the purposes of this Agreement. SECTION 1.11. APPRAISAL RIGHTS ---------------- (a) Each outstanding share of Company Common Stock as to which a written demand for appraisal is filed in accordance with Section 262 of the DGCL at or prior to the Company Stockholders Meeting (as hereinafter defined) and not withdrawn at or prior to the Company Stockholders Meeting and which is not voted in favor of the Merger shall not be converted into or represent a right to receive the Merger Consideration hereunder unless and until the holder shall have failed to perfect, or shall have effectively withdrawn or lost his or her right to appraisal of and payment for his or her Company Common Stock under such Section 262, at which time his or her Company Common Stock shall be treated in accordance with SECTION 1.11(b) below. All such Company Common Stock as to which such a written demand for appraisal is so filed and not withdrawn at or prior to the time of such vote and which are not voted in favor of the Merger, except any such Company Common Stock the holder of which, prior to the Effective Time, shall have effectively withdrawn or lost, his or her right to appraisal of and payment for his or her Company Common Stock under such Section 262, are herein called "Dissenting Shares." The Company shall give Parent prompt notice upon receipt by the Company of any written demands for appraisal rights, withdrawal of such demands, and any other instruments served pursuant to Section 262 of the DGCL, and the Company shall give Parent the opportunity to direct all negotiations and proceedings with respect to such demands. The Company shall not voluntarily make any payment with respect to any demands for appraisal rights and shall not, except with the prior written consent of the Parent, settle or offer to settle any such demands. Each holder of Company Common Stock who becomes entitled, pursuant to Section 262 of the DGCL, to payment for his or her Company Common Stock under the provisions of such section shall receive payment therefor from the Surviving Corporation and such Company Common Stock shall be cancelled. (b) If prior to the Effective Time any stockholder of the Company shall fail to perfect, or shall effectively withdraw or lose, his or her right to appraisal of and payment for his or her Dissenting Shares under Section 262 of the DGCL, the Company Common Stock of such holder shall be treated for purposes of this ARTICLE I like any other shares of Company Common Stock. If, after the Effective Time, any holder of Company Common Stock shall fail to perfect, or shall effectively withdraw or lose, his or her right to appraisal of and payment for his or her Dissenting Shares under Section 262 of the DGCL, each Dissenting Share of such holder shall be treated as though such share has been converted into the right to receive the Merger Consideration as provided in this ARTICLE I.

SECTION 5.4. ACQUISITION PROPOSALS. --------------------- (a) The Company shall not, nor shall it permit any of its Subsidiaries to, nor shall it authorize or permit any of its directors, officers or employees or any investment banker, financial advisor, attorney, accountant or other representative retained by it or any of its Subsidiaries to, directly or indirectly through another Person, (i) solicit, initiate or encourage (including by way of furnishing information), or take any other action to facilitate, any inquiries or the making of any proposal or offer other than the Merger that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal (as defined below) or (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information with respect to, or accept or implement any Acquisition Proposal; provided, however, that prior to the time at which the Company Requisite Vote shall have been obtained, the Company may, in response to an Acquisition Proposal received subsequent to the date hereof which did not result from a breach of this SECTION 5.4 and which the Board of Directors of the Company determines is reasonably likely to result in a Superior Proposal, and subject to providing prior written notice of its decision to take such action to Parent and compliance with SECTION 5.4, furnish information with respect to the Company and its Subsidiaries to any Person making such Acquisition Proposal pursuant to a customary confidentiality agreement which is (i) no less favorable to the Company and (ii) no less restrictive on the Person requesting such information than those contained in the Confidentiality Agreement, and participate in discussions or negotiations regarding such Acquisition Proposal. For purposes of this Agreement, "Superior Proposal" means any written proposal not solicited in breach of this SECTION 5.4 by the Company made by a third party to consummate a tender offer, exchange offer, merger, consolidation or similar transaction which would result in such third party (or its stockholders) owning, directly or indirectly, a majority of the shares of Company Common Stock then outstanding (or of the surviving entity in a merger) or all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, and otherwise on terms which a majority of the members of the Board of Directors of the Company determines in good faith (after consultation with outside counsel and its financial advisor) to be more favorable to the Company's stockholders, from a financial point of view, than the transactions contemplated by this Agreement. In reaching such good faith determination, the Board of Directors of the Company shall give significant consideration to whether any such third party proposal includes definitive financing and is reasonably capable of being consummated. For purposes of this Agreement, "Acquisition Proposal" means any inquiry, proposal or offer from any Person other than Parent relating to any direct or indirect acquisition or purchase of more than 10% of the total assets (including without limitation stock of Subsidiaries) of the Company and its Subsidiaries, taken as a whole, or any shares of any class or series of equity securities of the Company or any of its Subsidiaries constituting more than 10% of the outstanding shares of Company Common Stock, any tender offer or exchange offer involving more than 10% of the outstanding shares of Company Common Stock, or any merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company or any of its Subsidiaries, other than the transactions contemplated by this Agreement. (b) Neither the Company nor the Board of Directors of the Company nor any committee thereof shall (i) make a Change in the Company Board Recommendation (as defined in SECTION 5.6(a) below), (ii) approve or recommend any Acquisition Proposal, or (iii) approve or recommend, or execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement (each, an "Acquisition Agreement"), in any such case to permit or facilitate the consummation of an Acquisition Proposal, or agree to do any of the foregoing constituting or related to, or which is intended to or would reasonably be expected to lead to, any Acquisition Proposal. Notwithstanding the foregoing, at any time prior to the time at which the Requisite Company Vote shall have been obtained, in response to a Superior Proposal which did not result from a breach of SECTION 5.4(a), the Board of Directors of the Company may (subject to this sentence and the definition of the term "Superior Proposal"), after consultation with outside counsel and financial advisors, subject to payment of the termination fee provided for in SECTION 7.2 (if applicable), (i) make a Change in the Company Board Recommendation or (ii) approve or recommend a Superior Proposal or cause the Company or any of its Subsidiaries to enter into a definitive written agreement with respect to a Superior Proposal, but in each case referred to in the foregoing clauses (i) and (ii), only if the Company notifies Parent, in writing, at least 48 hours prior to taking any such action, of its intention to take such action, specifying the material terms of such Superior Proposal and identifying the Person making such Superior Proposal, and Parent does not make, on or before 5:00 p.m., New York City time, on the second Business Day following receipt of such written notification, an offer that the Board of Directors of the Company determines, in good faith, after consultation with its financial advisors, is at least as favorable to the stockholders of the Company as such Superior Proposal, it being understood that the Company shall not enter into any binding agreement with respect to such Superior Proposal prior to 5:00 p.m. New York City time, on the third Business Day following Parent's receipt of such written notification. (c) In addition to the obligations of the Company set forth in paragraphs (a) and (b) of this SECTION 5.4, the Company shall no later than 24 hours thereafter advise Parent orally and in writing of any information or of any inquiry with respect to an Acquisition Proposal, the material terms and conditions of such request, inquiry or Acquisition Proposal and the identity of the person making such request, inquiry or Acquisition Proposal. The Company will promptly keep Parent informed of the status and details (including amendments or changes or proposed amendments or changes) of any such request, inquiry or Acquisition Proposal. (d) Nothing contained in this SECTION 5.4 shall prohibit the Company complying with Rules 14d-9 and 14e-2 promulgated under the Exchange Act or from making any disclosure to the Company's stockholders if, in the good faith judgment of a majority of the members of the Board of Directors of the Company, after consultation with outside counsel, failure so to disclose would be inconsistent with its obligations under applicable law; provided, however, that, subject to SECTION 5.4(b), neither the Company nor its Board of Directors nor any committee thereof shall make a Change in the Company Board Recommendation (as defined below) or approve or recommend, or propose to approve or recommend, an Acquisition Proposal. (e) The Company agrees that it will, and will cause its officers, directors and representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any parties conducted heretofore with respect to any Acquisition Proposal. The Company agrees that it will use reasonable efforts to promptly inform its directors, officers, key employees, agents and representatives of the obligations undertaken in this SECTION 5.4. SECTION 5.5. INFORMATION SUPPLIED. -------------------- Each of the Company and Parent agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it or its Subsidiaries for inclusion or incorporation by reference in the proxy statement on Schedule 14A to be filed with the SEC by the Company in connection with stockholder approval of the Merger (the "Proxy Statement") will, at the time the Proxy Statement is mailed to the Company's stockholders and at the time of the Company Stockholders Meeting (as defined below) contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Board of Directors of the Company shall, subject to SECTION 5.4 and SECTION 5.6 include in the Proxy Statement its recommendation in favor of adoption of the Merger Agreement (the "Company Board Recommendation") and the written opinion of JP Morgan Chase, dated the date of this Agreement, to the effect that, as of the date hereof, the Merger Consideration is fair, from a financial point of view, to the holders of Company Common Stock. SECTION 5.6. STOCKHOLDERS MEETING. -------------------- (a) Unless there shall be a Change in the Company Board Recommendation (as defined below), the Company shall duly take all lawful action to call, give notice of, convene and hold a meeting of its stockholders on a date as soon as reasonably practicable (the "Company Stockholders Meeting") for the purpose of obtaining the required approval of its stockholders with respect to the transactions contemplated by this Agreement, and shall take all lawful action to solicit the adoption of this Agreement, by the requisite vote of its stockholders; and the Board of Directors of the Company shall make the Company Board Recommendation, and shall not withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to Parent such recommendation or the approval of the Merger or this Agreement or take any action or make any statement in connection with the Company Stockholders Meeting inconsistent with such recommendation or approval (collectively, a "Change in the Company Board Recommendation"); provided the foregoing shall not prohibit accurate disclosure (and such disclosure shall not be deemed to be a Change in the Company Board Recommendation) of material factual information regarding the business, financial condition or results of operations of Parent or the Company or the fact that an Acquisition Proposal has been made, the identity of the party making such proposal or the material terms of such proposal (provided, that the Board of Directors of the Company does not withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to Parent its recommendation), to the extent such information, facts, identity or terms is required to be disclosed under applicable law; and, provided further, that the Board of Directors of the Company may make a Change in the Company Board Recommendation pursuant to SECTION 5.4 hereof. If there is a Change in the Company Board Recommendation and/or this Agreement is terminated, this Agreement need not be submitted to a vote of the Company's stockholders. (b) For purposes of this Agreement, a Change in the Company Board Recommendation shall be deemed to include, without limitation, a recommendation by the Company Board of Directors of a third party Acquisition Proposal with respect to the Company. SECTION 5.7. FILINGS; OTHER ACTIONS; NOTIFICATION. ------------------------------------ (a) The Company shall (with the cooperation of the Parent) prepare and file with the SEC the Proxy Statement as promptly as practicable. Parent and the Company each shall use its reasonable best efforts to have the Proxy Statement mailed to the stockholders of the Company as promptly as practicable thereafter. (b) The Company and Parent each shall from the date hereof until the Effective Time cooperate with the other and use its reasonable best efforts to cause to be done all things necessary, proper or advisable on its part under this Agreement and applicable Laws to consummate and make effective the Merger and the other transactions contemplated by this Agreement as soon as practicable, including preparing and filing as promptly as practicable all documentation to effect all necessary notices, reports and other filings, including the Company providing any notices required under the Connecticut Property Transfer Act (Conn. Gen. Stat. ss.ss.22A-134 et seq.) and to obtain as promptly as practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any third party and/or any Governmental Entity, including filings under the Hart-Scott-Rodino Act, in order to consummate the Merger or any of the other transactions contemplated by this Agreement. Parent will advise the Company promptly in respect of any understandings or arguments which it proposes to make or has made with applicable federal, state or foreign governmental bodies having jurisdiction over or rights of review with respect to antitrust law, in connection with the Merger, and Parent and the Company shall use their reasonable best efforts to seek to resolve any objections to the Merger as may be asserted by a Governmental Entity under applicable laws. If necessary to obtain any regulatory approval pursuant to any applicable Law, or if any administrative or judicial action or proceeding, is instituted (or threatened to be instituted), challenging the Merger or any other transaction contemplated by this Agreement as violative of applicable antitrust or competition Law, each of Parent and the Company shall cooperate in all respects with each other and, if necessary, to (i) obtain any such regulatory approval, (ii) contest and resist any such action or proceeding or (iii) have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order made or granted pursuant thereto (whether, temporary, preliminary or permanent), then Parent and its Subsidiaries shall (i) sell, hold separate, or otherwise dispose of or conduct their business in a specified manner, (ii) agree to sell, hold separate or otherwise dispose of or conduct their business in a specified manner, or (iii) permit the sale, holding separate or other disposition of, any assets of Parent, the Company or their respective Subsidiaries or the conduct of their business in a specified manner, provided that in no event will Parent be required hereby to sell, hold separate or otherwise dispose of any material assets or business or agree to restrict in any way the conduct of any material business conducted by Parent or proposed to be conducted by Parent following the Merger. (c) The Company and Parent each shall keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby. (d) The Company and Parent each shall, upon request by the other, furnish the other with all information concerning itself, its Subsidiaries, directors, executive officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement or any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any third party and/or any Governmental Entity in connection with the Merger and the transactions contemplated by this Agreement. SECTION 5.8. COMPANY STOCK OPTIONS. --------------------- (a) Concurrent with the Effective Time, each Company Option outstanding and unexercised immediately prior to the Effective Time pursuant to the Company Stock Plans shall be assumed by the Parent and shall thereby be converted into an option (an "Assumed Option") to purchase the number of shares of Parent Common Stock (decreased to the nearest full share) determined by multiplying (i) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time by (ii) the Conversion Ratio (as defined below). The exercise price of each Company Option shall also be adjusted by dividing and rounding up to the nearest whole cent the exercise price for each share otherwise purchasable pursuant to each Company Option by the Conversion Ratio. Except for the foregoing adjustments, all the terms and conditions in effect for each Assumed Option immediately prior to the Effective Time shall continue in effect following the assumption of such option in accordance with this Agreement. "Conversion Ratio" means the Merger Consideration divided by the average of the closing price per share of the Parent Common Stock on the New York Stock Exchange for the five consecutive trading days ending on and including the trading day immediately prior to the day of the Effective Time. (b) It is the intention of the parties that the Company Options so assumed by Parent shall qualify, immediately after the Effective Time, as "Incentive Stock Options" under Section 422 of the Code to the same extent those options qualified as such Incentive Stock Options immediately prior to the Effective Time. Accordingly, the adjustments provided herein with respect to any Company Options that are Incentive Stock Options shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code. (c) Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon the exercise of the Assumed Options. As soon as practicable after the Effective Time, Parent shall deliver to the holders of Company Options appropriate notices setting forth such holders' rights pursuant to such Assumed Options and that such Assumed Options shall continue in effect on the same terms and conditions as the Company Options and the applicable Company Stock Plan (subject to the adjustment set forth in this SECTION 5.8). (d) As soon as practicable after the Effective Time, Parent shall prepare and file with the SEC a registration statement on Form S-8 (or another appropriate form) registering a number of shares subject to the Assumed Options. Such registration statement shall be kept effective (and the current status of the prospectus required thereby shall be maintained in accordance with the relevant requirements of the Securities Act and the Exchange Act) at least for so long as any Assumed Options remain outstanding. SECTION 5.9. NOTIFICATION OF CERTAIN MATTERS. ------------------------------- The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of the occurrence of any event which would be likely to cause (i) any representation or warranty made by such Person contained in this Agreement to be untrue or inaccurate in any material respect; or (ii) any covenant, condition or agreement made by such Person contained in this Agreement not to be complied with or satisfied; or (iii) any failure of the Company or Parent, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided that the delivery of any notice pursuant to this SECTION 5.9 shall not limit or otherwise affect the remedies available to the party receiving such notice. SECTION 5.10. INDEMNIFICATION. --------------- (a) From and after the Effective Time, Parent agrees that it will (i) indemnify and hold harmless, against any costs or expenses (including attorney's fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, and provide advancement of expenses to, all past and present directors, officers and employees of the Company and its Subsidiaries (in all of their capacities) (individually, an "Indemnified Party" and collectively the "Indemnified Parties") (a) to the same extent such persons are indemnified or have the right to advancement of expenses, and to the extent permitted by law, as of the date of this Agreement by the Company pursuant to the Company Charter Documents and indemnification agreements, if any, in existence on the date hereof with any directors, officers and employees of the Company and its Subsidiaries and (b) without limitation to clause (a), to the fullest extent permitted by law, in each case, for acts or omissions at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby), (ii) include and cause to be maintained in effect in the Surviving Corporation's (or any successor's) certificate of incorporation and bylaws for a period of six years after the Effective Time, the current provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses contained in the Company Charter Documents and (iii) use commercially reasonable efforts to maintain or cause to be maintained for a period of six years after the Effective Time the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by the Company (provided that Parent (or any successor) may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured and provided further that Parent shall not be required to pay an annual premium therefor in excess of 200% of the last annual premium paid for the Company's directors' and officers' liability insurance prior to the date of this Agreement) with respect to claims arising from facts or events that occurred on or before the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby). Without limiting the rights of any Indemnified Party set forth in this Section 5.10, such Indemnified Party shall be entitled to be represented by counsel of its choice reasonably acceptable to Parent, in any circumstance where the Indemnified Party reasonably believes that there is an actual or potential conflict of interest between Parent and the Indemnified Party, and subject to the terms of the then applicable insurance policies covering the Indemnified Parties, and Parent shall, and shall cause the Surviving Company to, pay as incurred the reasonable fees and expenses of such separate counsel, promptly after statements therefor are received. In no event shall Parent be liable for fees and expenses of more than one separate counsel and one local counsel for all Indemnified Parties in connection with any one action or related actions in the same jurisdiction arising out of the same general allegations or facts. No Indemnified Party shall, without the prior consent of Parent, settle or compromise or consent to the entry of any judgment with respect to any claim in respect of which indemnification could be sought hereunder. The obligations of Parent under this SECTION 5.10 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this SECTION 5.10 applies without the consent of such affected Indemnified Party (it being expressly agreed that the indemnities to whom this SECTION 5.10 applies shall be third party beneficiaries of this SECTION 5.10).
