AGREEMENT AND PLAN OF MERGER dated as of August 23, 2006 (this “Agreement”), by and among INTERNATIONAL BUSINESS MACHINES CORPORATION, a New York corporation (“Parent”), AEGIS ACQUISITION CORP, a Delaware corporation and a wholly owned subsidiary of Parent (“Sub”), and INTERNET SECURITY SYSTEMS, INC., a Delaware corporation (the “Company”).

WHEREAS the Board of Directors of each of the Company and Sub deems it in the best interests of their respective stockholders to consummate the merger (the “Merger”), on the terms and subject to the conditions set forth in this Agreement, of Sub with and into the Company in which the Company would become a wholly owned subsidiary of Parent, and such Boards of Directors have approved this Agreement and declared its advisability (and, in the case of the Board of Directors of the Company, recommended that this Agreement be adopted by the Company’s stockholders);

WHEREAS Parent, 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;

WHEREAS concurrently with the execution and delivery of this Agreement and as a condition to the willingness of Parent to enter into this Agreement, certain employees of the Company are executing and delivering offer letters (the “Offer Letters”) regarding the employment of such employees following the consummation of the Merger; and

WHEREAS concurrently with the execution and delivery of this Agreement and as a condition to the willingness of Parent to enter into this Agreement, certain stockholders and employees of the Company are entering into agreements with Parent pursuant to which such stockholders and employees shall agree, among other things, to certain non-competition, non-solicitation and no hire restrictions.

NOW, THEREFORE, in consideration of the foregoing and the respective 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 General Corporation Law of the State of Delaware (the “DGCL”), Sub shall be merged with and into the Company at the Effective Time. At the Effective Time, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (the “Surviving Corporation”).

SECTION 1.02. Closing. The closing of the Merger (the “Closing”) will take place at 10:00 a.m., New York time, on a date to be specified by the parties, which shall be not later than the second business day after satisfaction or waiver of the conditions set forth in Article VI (other than those that by their terms are to be satisfied or waived at the Closing, it being understood that the occurrence of the Closing shall remain subject to the satisfaction or waiver of such conditions at Closing), at the offices of Cravath, Swaine & ▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, unless another time, date or place is 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 of the Merger. Upon the terms and subject to the conditions set forth in this Agreement, as soon as practicable on or after the Closing Date, the parties shall file a certificate of merger (the “Certificate of Merger”) in such form as is required by, and executed and acknowledged in accordance with, the relevant provisions of the DGCL. The Merger shall become effective at such date and time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware or at such subsequent date and time as Parent and the Company shall agree and specify in the Certificate of Merger. The date and 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 Bylaws. (a) The Restated Certificate of Incorporation of the Company (the “Company Certificate”) shall be amended at the Effective Time to read in the form of Exhibit A hereto and, as so amended, the Company Certificate shall be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

(b) The Bylaws of Sub as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

SECTION 1.06. Directors. The directors of 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 Sub 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 Common Stock, par value $0.001 per share, of the Company (the “Company Common Stock”), or the holder of any shares of capital stock of Sub:

(a) Capital Stock of Sub. Each issued and outstanding share of common stock of Sub, par value $0.01 per share, shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(b) Cancelation of Treasury Stock and Parent-Owned Stock. All shares of Company Common Stock that are owned as treasury stock by the Company or owned by Parent or Sub immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and no consideration shall be delivered or deliverable 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 (i) shares to be canceled in accordance with Section 2.01(b), (ii) except as provided in Section 2.01(d), the Appraisal Shares and (iii) Restricted Shares to the extent set forth in Section 5.04) shall be converted into the right to receive $28.00 in cash, without interest (the “Merger Consideration”). At the Effective Time such shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate (or evidence of shares in book-entry form) 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 in accordance with the terms of this Agreement. The right of any holder of any share of Company Common Stock to receive the Merger Consideration shall be subject to and reduced by the amount of any withholding that is required under applicable tax Law, such withholding to be pursuant to the terms of Section 2.02(f) and any applicable tax Law.

(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, the Appraisal 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 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 such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 2.01(c). The Company shall serve prompt notice to Parent of any demands for appraisal of any shares of Company Common Stock, withdrawals of any such demands and any other instruments served pursuant to the DGCL received by the Company, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. 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 or commit 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 make available, or cause the Surviving Corporation to make available, 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 other amounts earned with respect to funds made available to the Paying Agent pursuant to this Agreement shall be turned over to Parent.

(b) Exchange Procedure. As soon as reasonably practicable after the Effective Time, the Surviving Corporation or Parent shall cause the Paying Agent to 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 a form and have such other provisions (including customary provisions with respect to delivery of an “agent’s message” with respect to shares held in book-entry form) as Parent may reasonably specify and which shall be reasonably acceptable to the

Company) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. 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 equal to the Merger Consideration that such holder has the right to receive 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, payment of the Merger Consideration in exchange therefor may be made 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 the Surviving Corporation 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 that were outstanding immediately prior to the Effective Time. If, after the close of business on the day on which the Effective Time occurs, 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, Sub, the Company or the Paying Agent shall be liable to any person in respect of any cash that would otherwise have been payable in respect of any Certificate which is properly delivered to a public official in accordance with 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 become the property of any Governmental Entity), any such Merger Consideration in respect thereof shall, to 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 the Surviving

Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall pay the Merger Consideration in respect of such lost, stolen, defaced or destroyed Certificate.

(f) Withholding Rights. Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Paying 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, the Surviving Corporation or the Paying Agent.

(g) Termination of Fund. At any time following the 18-month anniversary of the Closing Date, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) that had been made available to the Paying Agent and which have not been disbursed to holders of Certificates, and thereafter, subject to time limitations in Section 2.01(d), such holders shall be entitled to look only to Parent and the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the payment of any Merger Consideration that may be payable upon surrender of any Certificates held by such holders, as determined pursuant to this Agreement, without any interest thereon.

ARTICLE III

Representations and Warranties

SECTION 3.01. Representations and Warranties of the Company. Except as set forth in the letter (with specific reference to the Section of this Agreement to which the information stated in such disclosure relates; provided that information contained in any section of the Company Letter shall be deemed to be disclosed with respect to any other Section of this Agreement to the extent that it is readily apparent from the face of such disclosure that such information is applicable to such other Section of this Agreement) delivered by the Company to Parent prior to the execution of this Agreement (the “Company Letter”), the Company represents and warrants to Parent and Sub as follows:

The Company has made available to Parent complete and correct copies of the Company Certificate and the Bylaws of the Company (the “Company Bylaws”) and the certificate of incorporation and bylaws (or similar organizational documents) of each of its Subsidiaries, in each case as amended to the date of this Agreement. The Company has made available to Parent complete and correct copies of the minutes (or, in the case of draft minutes, the most recent drafts thereof) of all meetings of the stockholders, the Board of Directors and each committee of the Board of Directors of the Company and each of its Subsidiaries held since January 1, 2004.

(b) Subsidiaries. Section 3.01(b) of the Company Letter sets forth a complete and correct list of each Subsidiary of the Company, its place and form of organization. All the outstanding shares of capital stock of, or other equity or voting interests in, each such Subsidiary are owned by the Company, by another wholly owned Subsidiary of the Company or by the Company and another wholly owned Subsidiary of the Company, free and clear of all pledges, claims, liens, charges, options, security interests or other encumbrances of any kind or nature whatsoever (collectively, “Liens”), except for transfer restrictions imposed by applicable securities Laws, and are duly authorized, validly issued, fully paid and nonassessable.

Other than the Company Stock Plans, there is no plan or other Contract providing for the grant of options exercisable for or into shares of Company Common Stock by the Company or any of its Subsidiaries. No shares of Company Preferred Stock are issued or outstanding. No shares of Company Common Stock are owned by any Subsidiary of the Company. The Company has delivered to Parent (1) a complete and correct list, as of the close of business on August 18, 2006, of all outstanding Stock Options, the number of shares subject to each such Stock Option, the grant date, exercise price, vesting schedule and expiration date of each such Stock Option and the name of the holder thereof and an indication of whether or not each such holder is a current employee of the Company or any of its Subsidiaries and whether or not such Stock Option is intended to qualify as an “incentive stock option” under Section 422 of the Code and (2) a complete and correct list, as of the close of business on August 18, 2006, of all Restricted Shares and Stock Units, the grant date and the name of the holder of each such Restricted Share and Stock Units and the forms of Restricted Share and Stock Unit grant agreements pursuant to which any such Restricted Shares and Stock Units were granted that sets forth the date any forfeiture or repurchase conditions lapse and any repurchase price.

(ii) Except as set forth in Section 3.01(c)(i), as of the close of business on August 18, 2006, no shares of capital stock of, or other equity or voting interests in, the Company, or options, warrants, shares of deferred stock, restricted stock

awards, stock appreciation rights, phantom stock awards or other rights to acquire any such stock or securities, or other rights that are linked to the value of the Company Common Stock or the value of the Company or any part thereof, were issued, reserved for issuance or outstanding.

During the period from the date of this Agreement to the Effective Time, (i) the Company and each of its Subsidiaries shall timely file all material tax returns (“Post-Signing Returns”) required to be filed by each such entity (after taking into account any extensions), and all Post-Signing Returns shall be complete and correct in all material respects and shall be prepared on a basis consistent with the past practice of the Company; (ii) the Company and each of its Subsidiaries shall timely pay all taxes shown as due on such Post-Signing Returns; (iii) the Company will accrue a reserve in its books and records and financial statements in accordance with GAAP and past practice for all taxes payable by the Company or any of its Subsidiaries for which no Post-Signing Return is due prior to the Effective Time; (iv) the Company and each of its Subsidiaries will promptly notify Parent of any suit, claim, action, investigation, proceeding or audit pending against or with respect to the Company or any of its Subsidiaries in respect of any material tax and will not settle or compromise any such suit, claim, action, investigation, proceeding or audit without Parent’s prior written consent, which consent shall not be unreasonably withheld or delayed; (v) none of the Company or any of its Subsidiaries will amend any material tax

return or make or change any material tax election in each case without Parent’s consent, which consent shall not be unreasonably withheld or delayed; and (vi) the Company and each of its Subsidiaries will retain all books, documents and records necessary for the preparation of tax returns and reports and tax audits.

SECTION 4.02. No Solicitation. (a) Notwithstanding any provision in this Agreement to the contrary, the Company shall not, nor shall it permit any of its Subsidiaries to, nor shall it authorize or permit any director, officer or employee of the Company or any of its Subsidiaries or any investment banker, attorney, accountant or other advisor or representative of the Company or any of its Subsidiaries to, directly or indirectly (and it shall instruct and cause each applicable Subsidiary, if any, to instruct each such director, officer, employee, investment banker, attorney, accountant or other advisor or representative of the Company or any of its Subsidiaries not to), (i) solicit, initiate or knowingly encourage, or take any other action knowingly to facilitate, any Takeover Proposal or any inquiries or the making of any proposal that is reasonably likely to lead to a Takeover Proposal or (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any person (or any representative thereof) any information with respect to, or otherwise cooperate in any way with any person (or any representative thereof) with respect to, any Takeover Proposal; provided, however, that at any time prior to obtaining the Stockholder Approval, in response to a bona fide written unsolicited Takeover Proposal that the Board of Directors of the Company determines in good faith constitutes or is reasonably likely to lead to a Superior Proposal, and which Takeover Proposal did not result from a breach of this Section 4.02 or Section 4.01(a)(viii)(C), the Company may, and may permit and authorize its Subsidiaries and its and its Subsidiaries’ representatives to, in each case subject to compliance with Section 4.02(c), (A) furnish information with respect to the Company and its Subsidiaries to the person making such Takeover Proposal (and its representatives) pursuant to a confidentiality agreement which contains terms that are no less restrictive than those contained in the Confidentiality Agreement dated April 4, 2006, between Parent and the Company (as it may be amended from time to time, the “Confidentiality Agreement”), provided that all such information had been provided, or is concurrently provided, to Parent, and (B) participate in discussions or negotiations with the person making such Takeover Proposal (and its representatives) regarding such Takeover Proposal. Without limiting the generality of the foregoing, it is understood that any violation of the restrictions set forth in the preceding sentence by any director, officer or employee of the Company or any of its Subsidiaries or any investment banker, attorney, accountant or other advisor or representative of the Company or any of its Subsidiaries shall be deemed to be a breach of this Section 4.02(a) by the Company.

For purposes of this Agreement, the term “Takeover Proposal” means any inquiry, proposal or offer from any person (other than Parent or Sub or any affiliate of Parent or Sub) 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, stock acquisition, asset acquisition, binding

share exchange, business combination, recapitalization, liquidation, dissolution, joint venture, license agreement or similar transaction, of (i) assets or businesses that constitute or generate 15% or more of the total revenue, net income, EBITDA or assets of the Company and its Subsidiaries, taken as a whole, or (ii) 15% or more of the outstanding shares of Company Common Stock or of any class of capital stock of, or other equity or voting interests in, one or more of the Subsidiaries of the Company which, in the aggregate, directly or indirectly hold the assets or businesses referred to in clause (i) above.

For purposes of this Agreement, the term “Superior Proposal” means any binding bona fide unsolicited written offer, which did not result from a breach of Section 4.02(a), made by any person (other than Parent or Sub or any affiliate of Parent or Sub) that, if consummated, would result in such person (or in the case of a direct merger between such person and the Company, the stockholders of such person) acquiring, directly or indirectly, more than 50% 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, and which offer, in the good faith judgment of the Board of Directors of the Company (after consultation with a financial advisor of nationally recognized reputation and outside legal counsel), (i) is more favorable from a financial point of view to the Company’s stockholders than the Merger (taking into account all of the terms and conditions of such proposal and this Agreement (including the ability of the parties thereto to consummate the transactions contemplated thereby and any changes to the terms of this Agreement proposed by Parent in response to such Superior Proposal or otherwise)) and (ii) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal.

(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 Sub, or propose publicly to withdraw or modify in a manner adverse to Parent or Sub, the recommendation or declaration of advisability by such Board of Directors 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, or resolve or agree to take any such action (any such action, resolution or agreement to take such action being referred to herein as an “Adverse Recommendation Change”), (ii) adopt or approve any Takeover Proposal, or propose the approval or adoption of any Takeover Proposal, or resolve or agree to take any such action, or (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 resolve or agree to take any such action. Notwithstanding the foregoing, at any time prior to the Stockholder Approval, the Board of Directors of the Company may, in response to a Superior Proposal or an Intervening Event, effect an Adverse Recommendation Change, provided

that the Board of Directors of the Company determines in good faith, after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation, that the failure to do so is reasonably likely to result in a breach of its fiduciary duties to the stockholders of the Company under applicable Law, and provided, further, that the Board of Directors of the Company may not effect such an Adverse Recommendation Change unless (A) the Board of Directors shall have first provided prior written notice to Parent (an “Adverse Recommendation Change Notice”) that it is prepared to effect an Adverse Recommendation Change in response to a Superior Proposal or an Intervening Event, which notice shall, in the case of a Superior Proposal, attach the most current version of any written agreement or proposal relating to the transaction that constitutes such Superior Proposal, and, in the case of an Intervening Event, attach information describing such Intervening Event in reasonable detail, and (B) Parent does not make, within five business days after the receipt of such notice, a proposal that would, in the reasonable good faith judgment of the Board of Directors of the Company (after consultation with a financial advisor of national reputation and outside legal counsel), (x) cause the offer previously constituting a Superior Proposal to no longer constitute a Superior Proposal or (y) obviate the need for an Adverse Recommendation Change as a result of an Intervening Event. The Company agrees that, during the five business day period prior to its effecting an Adverse Recommendation Change, the Company and its officers, directors and representatives shall negotiate in good faith with Parent and its officers, directors, and representatives regarding any revisions to the terms of the transaction contemplated by this Agreement proposed by Parent.

For purposes of this Agreement the term “Intervening Event” means an event, unknown to the Board of Directors of the Company as of the date of this Agreement (or, if known, the material consequences of which are not known to or understood by the Board of Directors of the Company as of this Agreement), which event (or any material consequence of which) becomes known to or by (or understood by) the Board of Directors of the Company prior to the Stockholder Approval and which causes the Board of Directors of the Company to conclude in good faith, after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation, that its failure to effect an Adverse Recommendation Change is reasonably likely to result in a breach of its fiduciary duties to the stockholders of the Company under applicable Law; provided, however, that in no event shall the receipt, existence or terms of a Takeover Proposal or any matter relating thereto or consequence thereof constitute an Intervening Event.

(c) In addition to the obligations of the Company set forth in Sections 4.02(a) and 4.02(b), the Company shall, as promptly as possible and in any event within 24 hours after the Company first obtains knowledge of the receipt thereof, advise Parent orally and in writing of (i) any Takeover Proposal or any request for information or inquiry that the Company reasonably believes could lead to or contemplates a Takeover Proposal and (ii) the terms and conditions of such Takeover Proposal, request or inquiry (including any subsequent amendment or other modification

to such terms and conditions) and the identity of the person making any such Takeover Proposal, request or inquiry. Commencing upon the provision of any notice referred to above, once, and not more than once, each day at mutually reasonably agreeable times, the Company (or its outside counsel) shall (A) advise and confer with Parent (or its outside counsel) regarding the progress of negotiations concerning any Takeover Proposal, the material resolved and unresolved issues related thereto and the material terms (including material amendments or proposed amendments as to price and other material terms) of any such Takeover Proposal, request or inquiry and (B) promptly upon receipt or delivery thereof, provide Parent (or its outside counsel) with copies of all documents and written communications relating to any such Takeover Proposal, request or inquiry exchanged between the Company or any of its officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives, on the one hand, and the person making a Takeover Proposal or any of its officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives, on the other hand.

(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 14d-9 and 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 Directors of the Company, failure so to disclose is reasonably likely to be inconsistent with applicable Law; provided, however, that in no event shall the Company or its Board of Directors or any committee thereof take, agree or resolve to take any action prohibited by Section 4.02(b)(i), (ii) or (iii), except as expressly permitted by Section 4.02(b).

SECTION 4.03. Conduct by Parent. During the period from the date of this Agreement to the Effective Time, except as consented to in writing by the Company prior to such action or as specifically contemplated by this Agreement, Parent shall not, and shall not permit any of its Subsidiaries to, take any action that is reasonably likely to result in (a) any representation and warranty of Parent or Sub set forth in this Agreement that is qualified as to materiality becoming untrue (as so qualified) or (b) any such representation and warranty that is not so qualified becoming untrue in any material respect.

ARTICLE V

Additional Agreements

SECTION 5.01. Preparation of the Proxy Statement; Stockholders Meeting. (a) Subject to the reasonable cooperation of Parent, as promptly as practicable following the date of this Agreement, the Company shall prepare and, no later than the tenth business day immediately following the date of this Agreement, file with the SEC the preliminary Proxy Statement. Each of the Company and Parent shall use its

reasonable best efforts to cause the Proxy Statement to be cleared by the SEC as promptly as practicable after such filing. The Company will use its reasonable best efforts to cause the Proxy Statement to be mailed to the Company’s stockholders as promptly as practicable after the Proxy Statement is cleared by the SEC. Each of the Company and Parent shall furnish all information concerning such person and its affiliates to the other, and provide such other assistance, as may be reasonably requested in connection with the preparation, filing and distribution of the Proxy Statement. The Company shall promptly notify Parent upon the receipt of any comments from the SEC or any request from the SEC for amendments or supplements to the Proxy Statement and shall provide Parent with copies of all correspondence between it and its representatives, on the one hand, and the SEC, on the other hand. Each of the Company and Parent shall use reasonable best efforts to respond as promptly as practicable to any comments of the SEC with respect to the Proxy Statement. Notwithstanding the foregoing, prior to filing or mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, the Company (i) shall provide Parent an opportunity to review and comment on such document or response (including the proposed final version of such document or response), (ii) shall include in such document or response all comments promptly and reasonably proposed by Parent, and (iii) unless the Board of Directors of the Company shall have made an Adverse Recommendation Change, shall not file or mail such document, or respond to the SEC, prior to receiving the approval of Parent, which approval shall not be unreasonably withheld or delayed and in any event approval will be provided within two business days following a request therefor. If, at any time prior to the Stockholders Meeting, any information relating to the Company, Parent or any of their respective affiliates, officers or directors should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Proxy Statement, so that the Proxy Statement does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, the party that discovers such information shall as promptly as practicable notify the other parties hereto, and an appropriate amendment or supplement describing such information shall be filed with the SEC and, to the extent required by applicable Law, disseminated to the stockholders of the Company.

(b) The Company agrees that the Proxy Statement will comply as to form in all material respects with the requirements of the Exchange Act and that none of the information included or incorporated by reference in the Proxy Statement will (except to the extent revised or superseded by amendments or supplements contemplated hereby), at the date the Proxy Statement is filed with the SEC or mailed to the stockholders of the Company or at the time of the Stockholders Meeting, or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, except that no covenant is made by the Company with respect to statements made in the Proxy

Statement based on information supplied in writing by or on behalf of Parent for inclusion or incorporation for reference therein. Parent agrees that none of such information will (except to the extent revised or superseded by amendments or supplements contemplated hereby), at the date the Proxy Statement is filed with the SEC or mailed to the stockholders of the Company or at the time of the Stockholders Meeting, or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

(c) The Company shall, as promptly as practicable after the date of this Agreement, establish a record date (which will be as promptly as reasonably practicable following the date of this Agreement) for, duly call, give notice of, convene and hold a meeting of its stockholders, which meeting the Company shall, absent any Legal Restraint that has the effect of preventing such action, cause to occur no later than the 20th business day immediately following the date of mailing of the Proxy Statement (the “Stockholders Meeting”), for the purpose of obtaining the Stockholder Approval, regardless of whether the Board of Directors of the Company determines at any time that this Agreement is no longer advisable or recommends that the stockholders of the Company reject it or any other Adverse Recommendation Change has occurred at any time; provided, however, that (i) the Company may delay the Stockholders Meeting to the extent (and only to the extent) the Company reasonably determines that such delay is required by applicable Law to comply with comments made by the SEC with respect to the Proxy Statement and (ii) if the Board of Directors of the Company shall have delivered an Adverse Recommendation Change Notice to Parent, the Company may delay the Stockholders Meeting until one day after the expiration of the five-business day period immediately following delivery of such notice. The notice of such Stockholders Meeting shall state that a resolution to adopt this Agreement will be considered at the Stockholders Meeting. Subject to Section 4.02(b), the Board of Directors of the Company shall recommend to holders of the Company Common Stock that they adopt this Agreement, and shall include such recommendation in the Proxy Statement. Without limiting the generality of the foregoing, the Company agrees that its obligations pursuant to this Section 5.01(c) shall not be affected by the commencement, public proposal, public disclosure or communication to the Company or any other person of any Takeover Proposal.

SECTION 5.02. Access to Information; Confidentiality. (a) Subject to applicable Law or Judgment, (i) the Company shall, and shall cause each of its Subsidiaries to, afford to Parent and to Parent’s officers, employees, investment bankers, attorneys, accountants, consultants and other representatives and advisors reasonable access upon reasonable advance notice and during normal business hours during the period prior to the Effective Time or the termination of this Agreement to all their respective properties, assets, books, records, Contracts, Permits, documents, information, directors, officers and employees, and during such period the Company shall, and shall

cause each of its Subsidiaries to, make available to Parent any information concerning its business as Parent may reasonably request (including the work papers of Ernst & Young LLP) subject to the requirements of Ernst & Young LLP) and (ii) following the date of this Agreement and prior to the Effective Time, Parent may (but shall not be required to), following reasonable notice to the Company, contact and interview any Company Personnel as Parent may reasonably request; provided that Parent and its representatives shall coordinate any such activities with the Company with a view towards not unreasonably interfering with the business or operations of the Company. No investigation by Parent or any of its officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives and no other receipt of information by Parent or any of its officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives shall operate as a waiver or otherwise affect any representation or warranty of the Company or any covenant or other provision in this Agreement. Except as required by any applicable Law or Judgment, Parent will hold, and will direct its officers, employees, investment bankers, attorneys, accountants and other advisors and representatives to hold, any and all information received from the Company confidential in accordance with the Confidentiality Agreement and will comply with the terms of the Confidentiality Agreement.

(b) Without limiting the generality of the foregoing, during the period from the date of this Agreement to the Effective Time, the Company shall, and shall cause each of its Subsidiaries to, as and to the extent requested by Parent, provide Parent with (i) a complete and correct list of all licenses issued by the Federal Communications Commission (the “FCC”) and held by the Company or any of its Subsidiaries (the “FCC Licenses”), (ii) complete and correct copies of each FCC License, which FCC Licenses contain: (A) the address and physical location of the device(s) covered by each FCC License, and (B) a written description of the purpose of the device(s) covered by each FCC License, (iii) complete and correct copies of any Notices of Apparent Liability for Forfeiture issued by the FCC against the Company or any of its Subsidiaries and (iv) all information reasonably necessary for Parent to make an independent determination that the Company and its Subsidiaries have complied with FCC rules regarding changes of ownership control of the FCC Licenses (including descriptions of any transactions that effected a change of ownership or control of the FCC Licenses (including any intracompany reorganizations) and corporate organizational charts depicting the ownership structure of the holder of the FCC Licenses before and after any such change of ownership or control).

(c) The Company and Parent shall, and shall cause each of their respective Subsidiaries to, reasonably cooperate to ensure an orderly transition and integration process in connection with the Merger and the other transactions contemplated by this Agreement in order to minimize the disruption to, and preserve the value of, the business of the Surviving Corporation and its Subsidiaries.

SECTION 5.03. Reasonable Best Efforts; Consultation and Notice. (a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective the Merger and the other transactions contemplated by this Agreement, including using its reasonable best efforts to accomplish the following: (i) the satisfaction of the conditions precedent set forth in Article VI, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from, and the giving of any necessary notices to, Governmental Entities and other persons and the making of all necessary registrations, declarations and filings (including filings under the HSR Act and other registrations, declarations and filings with, or notices to, Governmental Entities, if any), (iii) the taking of all reasonable steps to provide any supplemental information requested by a Governmental Entity, including participating in meetings with officials of such entity in the course of its review of this Agreement, the Merger or the other transactions contemplated by this Agreement, (iv) the taking of all reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity or other person and (v) the obtaining of all necessary consents, approvals or waivers from any third parties; provided, that this clause (v) shall not limit the rights of the Company or its Board of Directors under Section 4.02(b). In connection with and without limiting the generality of the foregoing, each of the Company and its Board of Directors shall, if any state takeover statute or similar statute or regulation is or becomes applicable to this Agreement or any of the Merger and the other transactions contemplated by this Agreement, use its reasonable best efforts to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on this Agreement, the Merger and the other transactions contemplated by this Agreement. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Parent or Sub be obligated to, and the Company and its Subsidiaries shall not without the prior written consent of Parent, agree or proffer to divest or hold separate, or enter into any licensing or similar arrangement with respect to, any assets (whether tangible or intangible) or any portion of any business of Parent, the Company or any of their respective Subsidiaries. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Parent or any of its Subsidiaries be obligated to litigate or participate in the litigation of any suit, claim, action, investigation or proceeding, whether judicial or administrative, brought by any Governmental Entity (i) challenging or seeking to restrain or prohibit the consummation of the Merger or any of the other transactions contemplated by this Agreement, or seeking to obtain from Parent or any of its Subsidiaries any damages in relation therewith; (ii) seeking to prohibit or limit in any respect, or place any conditions on, the ownership or operation by the Company, Parent or any of their respective affiliates of all or any portion of the business or assets or any product of the Company or its Subsidiaries or Parent or its Subsidiaries or to require any such person to dispose of, license (whether pursuant to an exclusive or nonexclusive license) or hold separate all or any portion of the business or assets or any product of the Company or its

Subsidiaries or Parent or its Subsidiaries, in each case as a result of or in connection with the Merger or any of the other transactions contemplated by this Agreement; (iii) seeking to directly or indirectly impose limitations on the ability of Parent or any of its affiliates to acquire or hold, or exercise full rights of ownership of, any shares of Company Common Stock or any shares of common stock of the Surviving Corporation, including the right to vote the Company Common Stock or the shares of common stock of the Surviving Corporation on all matters properly presented to the stockholders of the Company or the Surviving Corporation, respectively; or (iv) seeking to (A) directly or indirectly prohibit Parent or any of its affiliates from effectively controlling in any respect any of the business or operations of the Company or its Subsidiaries or (B) directly or indirectly prevent the Company or its Subsidiaries from operating any of their business in substantially the same manner as operated by the Company and its Subsidiaries immediately prior to the date of this Agreement. The Company and Parent shall provide such assistance, information and cooperation to each other as is reasonably required to obtain any such actions, nonactions, waivers, consents, approvals, orders and authorizations and, in connection therewith, shall notify the other person promptly following the receipt of any comments from any Governmental Entity and of any request by any Governmental Entity for amendments, supplements or additional information in respect of any registration, declaration or filing with, or notice to, such Governmental Entity and shall supply the other person with copies of all correspondence between such person or any of its representatives, on the one hand, and any Governmental Entity, on the other hand.

(b) (i) In connection with the continuing operation of the business of the Company and its Subsidiaries between the date of this Agreement and the Effective Time, subject to applicable Law, the Company shall consult in good faith on a reasonably regular basis with Parent to report material, individually or in the aggregate, operational developments, the general status of relationships with customers and resellers, the general status of ongoing operations and other matters reasonably requested by Parent pursuant to procedures reasonably requested by Parent; provided, however, that no such consultation shall affect the representations, warranties, covenants, agreements or obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(ii) Except as prohibited by applicable Law, the Company shall promptly notify Parent of:

(A) the occurrence of any matter or event that (1) is, or that is reasonably likely to be, material, in an adverse manner, to the business, assets, properties, financial condition or results of operations of the Company and its Subsidiaries, taken as a whole, or (2) has resulted, or is reasonably likely to result, in (I) any representation and warranty of the Company set forth in this Agreement becoming untrue or inaccurate such that the condition set forth in Section 6.02(a) would not be satisfied or (II) any other condition to the transactions contemplated hereby and set forth in Section 6.02 not being satisfied;

(B) the failure of the Company to perform any obligation to be performed by it under this Agreement such that the condition set forth in Section 6.02(b) would not be satisfied;

(C) any material notice or other material communication from any person (other than a Governmental Entity) reasonably alleging that the consent of such person is required in connection with the Merger or any of the other transactions contemplated by this Agreement;

(D) any notice or other communication from any Major Customer or Major Supplier to the effect that such Major Customer or Major Supplier is terminating or otherwise materially adversely modifying its relationship with Company or any of its Subsidiaries as a result of the Merger or any of the other transactions contemplated by this Agreement;

(E) any material notice or other material communication from any Governmental Entity in connection with the Merger or any of the other transactions contemplated hereby, and a copy of any such notice or communication (if in written form) shall be promptly furnished to Parent; and

(F) any actions, suits, claims, investigations or proceedings commenced or, to the knowledge of the Company, threatened against, relating to or involving or otherwise affecting the Company or any of its Subsidiaries that, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to Section 3.01(h) or that relate to the consummation of the Merger or any of the other transactions contemplated by this Agreement;

provided, however, that no such notification shall affect the representations, warranties, covenants, agreements or obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(iii) Parent shall give prompt notice to the Company of (A) any representation or warranty made by Parent or Sub contained in this Agreement becoming untrue or inaccurate such that the condition set forth in Section 6.03(a) would not be satisfied, (B) the failure of Parent or Sub to perform any obligation to be performed by such party under this Agreement such that the condition set forth in Section 6.03(b) would not be satisfied; provided, however, that no such notification shall affect the representations, warranties, covenants, agreements or obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(c) Without limiting the generality of the foregoing, the Company shall give Parent the opportunity to participate in the defense of any litigation against the Company and/or its directors relating to the Merger or the other transactions contemplated by this Agreement, and will obtain the prior written consent of Parent prior to settling or satisfying any such claim (which consent shall, solely in the case of any Material Litigation that has resulted in any condition set forth in Section 6.02(c) not being satisfied, not be unreasonably withheld; provided, however, that no litigation shall be considered Material Litigation for purposes of this Section 5.03 if Parent shall have waived any condition to Closing to the extent such condition is not satisfied as a result of such litigation as of the date that all other conditions to closing shall have been satisfied or waived by Parent); provided that nothing in this Section 5.03(c) shall obligate Parent to agree or consent to the Company or any Subsidiary divesting, holding separate, or entering into any licensing or similar arrangement with respect to, any assets (whether tangible or intangible); and provided further that it is understood and agreed that this Section 5.03(c) shall not give Parent the right to direct such defense.

SECTION 5.04. Equity Awards. (a) As soon as practicable following the date of this Agreement, the Company agrees that the Board of Directors of the Company (or, if appropriate, any committee administering the Company Stock Plans) shall adopt such resolutions or take such other actions (including obtaining any required consents) as may be required to effect the following:

(i) at the Effective Time, each Vested Employee Stock Option other than a Rolled-Over Stock Option or an Affected Stock Option shall be canceled and each holder thereof shall be entitled to receive in consideration for such cancelation an amount in cash equal to the product of (A) the number of shares of Company Common Stock that are subject to such Vested Employee Stock Option immediately prior to the Effective Time and (B) the excess, if any, of the Merger Consideration over the exercise price per share of Company Common Stock subject to such Vested Employee Stock Option, which amount shall be payable to such holder at or as soon as practicable following the Effective Time;

(ii) at the Effective Time, each Non-Employee Stock Option shall be canceled and each holder thereof shall be entitled to receive in consideration for such cancelation an amount in cash equal to the product of (A) the number of shares of Company Common Stock that are subject to such Non-Employee Stock Option immediately prior to the Effective Time and (B) the excess, if any, of the Merger Consideration over the exercise price per share of Company Common Stock subject to such Non-Employee Stock Option, which amount shall be payable to such holder at or as soon as practicable following the Effective Time;

(iii) Subject to the Offer Letters, each Rolled-Over Stock Option shall be converted at the Effective Time into an option to acquire, on the same terms and conditions as were applicable under such Rolled-Over Stock Option (other than with respect to exercisability prior to vesting or the ability to pay the exercise price by tendering previously owned shares of Company Common Stock), the number of shares of Parent common stock, par value $0.20 per share (“Parent Common Stock”) (rounded down to the nearest whole share), determined by multiplying the number of shares of Company Common Stock subject to such Rolled-Over Stock Option immediately prior to the Effective Time by the Option Exchange Ratio, at an exercise price per share of Parent Common Stock (rounded up to the nearest whole cent) equal to (A) the exercise price per share of Company Common Stock otherwise purchasable pursuant to such Rolled-Over Stock Option divided by (B) the Option Exchange Ratio (each Rolled-Over Stock Option as so adjusted, an “Adjusted Option”);

(vi) Subject to the Offer Letters, each Employee Restricted Share outstanding at the Effective Time shall be converted at the Effective Time into the right to receive an amount of cash equal to the Merger Consideration (each Employee Restricted Share as so converted, a “Restricted Share Cash Amount”), the payments of which shall be subject to, and shall be made to the holder of such Employee Restricted Share (each, an “RS Holder”) in accordance with, Section 5.04(c) hereof, provided, however, that Restricted Shares granted under the 1995 Plan that are held by RS Holders who have not executed Offer Letters or otherwise consented to the foregoing treatment prior to the Effective Time (the “Cash-Out Restricted Shares”) shall be subject to Section 5.04(a)(vii) and not subject to this Section 5.04(a)(vi) or Section 5.04(c);

(vii) Each Cash-Out Restricted Share outstanding at the Effective Time shall be adjusted as necessary to provide that the restrictions on such share shall lapse at the Effective Time, and at the Effective Time, such Cash-Out Restricted Share shall be converted into the right to receive the Merger Consideration in accordance with Section 2.01(c), subject to any applicable withholding pursuant to Section 2.02(f), which amount shall be payable to the holder of such Cash-Out Restricted Share at or as soon as practicable following the Effective Time;

(viii) Subject to the Offer Letters, each Employee Stock Unit shall be converted at the Effective Time into a restricted stock unit, subject to the same terms and conditions as were applicable under such Employee Stock Unit (other than with respect to performance-based vesting), with respect to a number of shares of Parent Common Stock determined by multiplying the number of Company Common Stock subject to such Employee Stock Unit immediately prior to the Effective Time by the Option Exchange Ratio (rounded down to the nearest whole share) (each Employee Stock Unit so adjusted, an “Adjusted RSU”);

(ix) each Non-Employee Restricted Share outstanding at the Effective Time shall be converted at the Effective Time into the right to receive an amount of cash equal to the Merger Consideration, which amount shall be payable to the holder of such Non-Employee Restricted Share at or as soon as practicable following the Effective Time;

For purposes of this Agreement, (i) ”Applicable RS Portion” means, in respect of each such RS Holder, an amount equal to the product of the Merger Consideration and the number of Employee Restricted Shares held by such RS Holder at the Effective Time that would have vested or with respect to which the Company’s right to repurchase would have lapsed on the applicable Lapse Date; and (ii) ”Lapse Date” means, in respect of any Employee Restricted Shares, each date on which such shares would have vested or the Company’s right to repurchase such shares or units would have lapsed pursuant to such terms and conditions as were applicable to such Employee Restricted Shares immediately prior to the Effective Time.

connection with the performance of services for the Company or any of its Subsidiaries to any person who is an employee or officer of the Company or any of its Subsidiaries at the Effective Time; (v) ”Non-Employee Restricted Share” means a Restricted Share outstanding immediately prior to the Effective Time that is not an Employee Restricted Share; (vi) ”Non-Employee Stock Option” means a Stock Option (other than those granted under the ESPP) outstanding immediately prior to the Effective Time that is not an Employee Stock Option; (vii) ”Non-Employee Stock Unit” means a Stock Unit outstanding immediately prior to the Effective Time that is not an Employee Stock Unit; (viii) “Option Exchange Ratio” means a fraction, the numerator of which is the Merger Consideration and the denominator of which is the average closing price per share of Parent Common Stock on the New York Stock Exchange Composite Transactions Tape on the ten trading days immediately preceding the date on which the Effective Time occurs; (ix) ”Rolled-Over Stock Option” means (A) an Employee Stock Option that is not a Vested Employee Stock Option and (B) a Vested Employee Stock Option with an exercise price per share of Company Common Stock equal to or less than $36.40 and equal to or greater than the per share Merger Consideration; and (x) ”Vested Employee Stock Option” means an Employee Stock Option that is vested and unexercised as of immediately prior to the Effective Time.

(e) On or before the date on which any Adjusted Option becomes vested, Parent shall either (i) prepare and file with the SEC a registration statement on Form S-8 (or another appropriate form) registering a number of shares of Parent Common Stock equal to the number of shares subject to such Adjusted Option or (ii) assume such Adjusted Option under an existing equity incentive plan of Parent or any of its affiliates with respect to which a registration statement on Form S-8 (or another appropriate form) is currently effective. Any such registration statement shall be kept effective (and the current status of the prospectus or prospectuses required thereby shall be maintained) as long as any Adjusted Option may remain outstanding.

(f) The adjustments provided in Section 5.04(a) with respect to any Stock Options that are “incentive stock options” (as defined in Section 422 of the Code) are intended to be effected in a manner that is consistent with Section 424(a) of the Code.

(g) All amounts payable pursuant to this Section 5.04 shall be subject to any required withholding of taxes and shall be paid without interest.

SECTION 5.05. Indemnification, Exculpation and Insurance. (a) Parent and Sub agree that all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors or officers of the Company and its Subsidiaries as provided in their respective certificates of incorporation or bylaws (or comparable organizational documents) and any indemnification or other agreements of the Company as in effect on the date of this Agreement shall be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time, and

shall survive the Merger and shall continue in full force and effect in accordance with their terms, and Parent shall cause the Surviving Corporation to comply with and honor the foregoing obligations without termination or modification thereof.

(b) In the event that the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all its properties and assets to any person, or if Parent dissolves the Surviving Corporation then, and in each such case, Parent shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation assume the obligations set forth in this Section 5.05.

(c) Parent shall obtain as of the Effective Time a “tail” insurance policy with a claims period of six years from the Effective Time with respect to 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 that are no less favorable than those of such policy of the Company in effect on the date of this Agreement, which insurance shall, prior to the Closing, be in effect and prepaid for such six year period; provided, that in no event shall Parent or the Surviving Corporation be required to pay, with respect to the entire six year period following the Effective Time, premiums for insurance under this Section 5.05(c) which in the aggregate exceed 300% of the aggregate premiums paid by the Company for the period from March 24, 2006 to, and including, March 24, 2007, for such purpose (which premiums for such period are hereby represented and warranted by the Company to be $753,000); provided that Parent shall nevertheless be obligated to provide such coverage, with respect to the entire six year period following the Effective Time, as may be obtained for such 300% amount. For the avoidance of doubt, nothing in this Section 5.05(c) shall require Parent to make expenditures exceeding $2,259,000 in the aggregate.

(d) The provisions of this Section 5.05(i) are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise. The obligations of Parent and the Surviving Corporation under this Section 5.05 shall not be terminated or modified in such a manner as to adversely affect the rights of any indemnified party to whom this Section 5.05 applies unless (i) such termination or modification is required by applicable Law or (ii) the affected indemnified party shall have consented in writing to such termination or modification.

SECTION 5.06. Fees and Expenses. (a) Except as expressly set forth in this Section 5.06, all fees and expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated.

(b) In the event that (i) a Takeover Proposal has been publicly made known to the Company or shall have been made directly to its stockholders or any person has publicly announced an intention (whether or not conditional and whether or not withdrawn) to make a Takeover Proposal or a Takeover Proposal otherwise becomes widely known to the stockholders of the Company and thereafter (A) this Agreement is terminated by either Parent or the Company pursuant to Section 7.01(b)(i) or Section 7.01(b)(iii) and (B) prior to the date that is 12 months after such termination, the Company or any of its Subsidiaries enters into any Acquisition Agreement with respect to any Takeover Proposal or any Takeover Proposal is consummated (solely for purposes of this Section 5.06(b)(i)(B), the term “Takeover Proposal” shall have the meaning set forth in the definition of Takeover Proposal contained in Section 4.02(a) except that all references to 15% shall be deemed references to 40%) or (ii) this Agreement is terminated by Parent pursuant to Section 7.01(c), then, in each such case, the Company shall pay Parent a fee equal to $37,000,000 (the “Termination Fee”) by wire transfer of same-day funds to an account designated by Parent (A) in the case of a termination by Parent pursuant to Section 7.01(c), within two business days after such termination and (B) in the case of a payment as a result of any event referred to in Section 5.06(b)(i)(B), no later than the first to occur of such events.

(c) The Company acknowledges that the agreements contained in this Section 5.06 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not have entered into this Agreement. Accordingly, if the Company fails promptly to pay the amounts due pursuant to this Section 5.06 and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for the amounts set forth in this Section 5.06, the Company shall pay to Parent its reasonable costs and expenses (including attorneys’ fees and expenses) in connection with such suit and any appeal relating thereto, together with interest on the amounts set forth in this Section 5.06 at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made. Parent and Sub acknowledge that in no event shall the Company be required to pay the fee referred to in this Section 5.06 on more than one occasion.

SECTION 5.07. Public Announcements. The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the parties. Parent and Sub, on the one hand, and the Company, on the other hand, shall, to the extent at all reasonably practicable, consult with each other before making, and give each other a reasonable opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the Merger and the other transactions contemplated hereby and shall not issue any such press release or make any such public statement prior to such reasonably practicable consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system; provided, however, that each of Parent and the Company may make any public statement in response to specific questions by the press,

analysts, investors or those attending industry conferences or financial analyst conference calls, so long as such statements are substantially similar to previous press releases, public disclosures or public statements made jointly by Parent and the Company (or individually, if made in compliance with the foregoing provisions of this Section 5.07). For the avoidance of doubt, in the event a Takeover Proposal that is not a Superior Proposal is made, then, as and to the extent required by its fiduciary duties to the stockholders of the Company under applicable Law, the Board of Directors of the Company shall in no way be limited in communicating to the stockholders of the Company the reasons it did not withdraw its recommendation of this Agreement or the Merger as a result of such Takeover Proposal, and such communications shall not constitute an Adverse Recommendation Change.

SECTION 5.08. Sub Compliance. Parent shall cause Sub to comply with all of Sub’s obligations under this Agreement.

SECTION 5.09. Company Rights Agreement. The Board of Directors of the Company shall take all further actions (in addition to those referred to in Section 3.01(s)) reasonably requested by Parent in order to render the Company Rights inapplicable to this Agreement, the Merger, the other transactions contemplated by this Agreement and compliance with the terms of this Agreement. Except as provided above with respect to this Agreement, the Merger and the other transactions contemplated by this Agreement, the Board of Directors of the Company shall not, without the prior written consent of Parent, amend, modify, take any action with respect to, or make any determination under, the Company Rights Agreement.

SECTION 5.10. Certain Pre-Closing Actions. Prior to the Closing, the Company shall take all actions set forth on Section 5.10 of the Company Letter.

Each of the parties hereto irrevocably and unconditionally waives (and agrees not to plead or claim), any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware) or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 8.10. Waiver of Jury Trial. Each party hereto hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any suit, action or other proceeding directly or indirectly arising out of, under or in connection with this Agreement.
