ARTICLE II

CONVERSION OF SECURITIES

2.1   Conversion of Capital Stock.   As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of the capital stock of the Company or capital stock of the Acquisition Sub:

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

(b)   Cancellation of Treasury Stock and Buyer-Owned Stock.   All shares of common stock, par value $0.01 per share of the Company (the “Company Common Stock”) including the associated Preferred Stock Purchase Rights (the “Company Rights” and, together with the Company Common Stock, the “Shares”) issued pursuant to the Rights Agreement, dated as of October 25, 2002, between the Company and SunTrust Bank (the “Company Rights Plan”) that are owned by the Company as treasury stock and all Shares held by any wholly owned Subsidiary of the Company, the Buyer, the Acquisition Sub or any other wholly owned Subsidiary of the Buyer immediately prior to the Effective Time shall be automatically cancelled and shall cease to exist and no stock of the Buyer or other consideration shall be delivered in exchange therefor.

(c)   Merger Consideration for Company Common Stock.   Subject to Section 2.2, each Share (other than Shares to be cancelled in accordance with Section 2.1(b) and Dissenting Shares (as defined in Section 2.4(a) below)) issued and outstanding immediately prior to the Effective Time shall be automatically converted into the right to receive $27.50 (less applicable withholding Taxes) in cash (the “Merger Consideration”). As of the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration pursuant to this Section 2.1(c) upon the surrender of such certificate in accordance with Section 2.2, without interest.

2

(d)   Adjustments to Merger Consideration.   The Merger Consideration shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time.

2.2   Exchange of Certificates.   The procedures for exchanging outstanding Shares for the Merger Consideration pursuant to the Merger are as follows:

(a)   Paying Agent.   At or prior to the Effective Time, the Buyer shall deposit with a bank or trust company mutually acceptable to the Buyer and the Company (the “Paying Agent”), for the benefit of the holders of Shares outstanding immediately prior to the Effective Time, for payment through the Paying Agent in accordance with this Section 2.2, cash in an amount sufficient to make payment of the Merger Consideration pursuant to Section 2.1(c) in exchange for all of the outstanding Shares (the “Exchange Fund”). The Exchange Fund shall not be used for any other purpose. The Exchange Fund shall be invested by the Paying Agent as directed by the Buyer. Any net profit resulting from, or interest or income produced by, such Exchange Fund will be payable to the Buyer or as the Buyer otherwise directs and any loss resulting from the investment of such Exchange Fund shall be borne by the Buyer and shall not diminish any amount payable by the Buyer in exchange for the Shares pursuant to this Agreement.

(b)   Exchange Procedures.   Promptly (and in any event within five (5) Business Days) after the Effective Time, the Buyer shall cause the Paying Agent to mail to each holder of record of a certificate (or evidence of shares in book-entry form) which immediately prior to the Effective Time represented outstanding Shares (each, a “Certificate”) entitled to receive Merger Consideration pursuant to Section 2.1(c) a letter of transmittal in customary form and (ii) instructions for effecting the surrender of the Certificates in exchange for the Merger Consideration payable with respect thereto. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be paid, promptly in exchange therefor, cash in an amount equal to the Merger Consideration that such holder has the right to receive pursuant to the provisions of this Article II, and the Certificate so surrendered shall immediately be cancelled. No interest will be paid or accrued on the cash payable upon the surrender of such Certificate or Certificates. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, the Merger Consideration may be paid to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid and the Person requesting such payment pays any transfer or other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or establishes to the reasonable satisfaction of the Buyer that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration as contemplated by this Section 2.2. As used in this Agreement, “Person” means any individual, corporation, partnership, limited liability company, joint venture, association, trust, Governmental Entity, unincorporated organization or other entity.

(c)   No Further Ownership Rights in Company Common Stock.   All Merger Consideration paid upon the surrender of Certificates in accordance with the terms hereof shall be deemed to have been paid in satisfaction of all rights pertaining to the Shares formerly represented by such Certificates, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares which were outstanding immediately prior to the Effective Time. Subject to the last sentence of Section 2.2(d), if, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

3

(d)   Termination of Exchange Fund.   Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for one (1) year after the Effective Time shall be delivered to the Buyer, upon demand, and any holder of Shares who has not previously complied with this Section 2.2 shall be entitled to receive only from the Buyer payment of its claim for Merger Consideration, without interest. Any amount remaining unclaimed by such holders at such time at which amounts would otherwise escheat to or become property of any Governmental Entity shall become, to the extent permitted by applicable Law, the property of the Buyer free and clear of any and all claims or interests of any Person previously entitled thereto.

(e)   No Liability.   To the extent permitted by applicable Law, none of the Buyer, the Acquisition Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any holder of Shares delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(f)   Withholding Rights.   Each of the Buyer, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares and/or Company Stock Options such amounts as it 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 other applicable state, local or foreign Tax law. To the extent that amounts are so withheld by the Surviving Corporation, the Buyer or the Paying Agent, as the case may be, such withheld amounts (i) shall be remitted by the Buyer, the Surviving Corporation or the Paying Agent, as the case may be, to the applicable Governmental Entity, and (ii) shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares and/or Company Stock Options in respect of which such deduction and withholding was made by the Surviving Corporation, the Buyer or the Paying Agent, as the case may be.

(g)   Lost Certificates.   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, if required by the Buyer or the Paying Agent, the posting by such Person of a bond in such reasonable amount as the Buyer or the Paying Agent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the Shares formerly represented thereby pursuant to this Agreement.

(h)   Expenses.   The Buyer or the Acquisition Sub shall bear and pay all charges and expenses, including those of the Paying Agent, incurred in connection with the payment for Shares.

2.3   Company Stock Plans.

(a)   Cash-Out of Vested Company Stock Options at Spread.   Immediately after the Effective Time, each outstanding option to purchase shares of Company Common Stock (“Company Stock Options”) that is vested in accordance with its terms at the Effective Time (each a “Vested Company Stock Option”) shall, to the extent so vested, without any action on the part of the Company or the holder of such option, automatically be cancelled and exchanged for a cash payment by the Buyer or the Acquisition Sub (which shall be made promptly after the Effective Time) in an amount equal to (i) the excess, if any, of (x) the Merger Consideration per share of Company Common Stock over (y) the exercise price per share of Company Common Stock subject to such Vested Company Stock Option, multiplied by (ii) the number of shares of Company Common Stock for which such Vested Company Stock Option is vested and exercisable immediately prior to the Effective Time.

(b)   Assumption of Unvested Company Stock Options.   At the Effective Time, each outstanding Company Stock Option that is unvested in accordance with its terms at the Effective Time (each an “Unvested Company Stock Option”) shall, without any action on the part of the Company or any holder of such options, automatically be assumed by the Buyer together with all stock option plans or other

4

equity-related plans of the Company (the “Company Stock Plans”) insofar as they relate to outstanding Unvested Company Stock Options, and each option so assumed shall, without any action on the part of the Company or the holder of such option, to the extent so unvested, automatically become an option to acquire, on the same terms and conditions as were applicable under the Unvested Company Stock Option immediately prior to the Effective Time, a number of shares of common stock, $0.01 par value per share, of the Buyer (“Buyer Common Stock”) determined as follows:

(i)    the number of shares of Buyer Common Stock subject to each Company Stock Option assumed by the Buyer shall be determined by multiplying the number of shares of Company Common Stock that were subject to such Unvested Company Stock Option immediately prior to the Effective Time by the Conversion Ratio (as defined below), and rounding the resulting number down to the nearest whole number of shares of Buyer Common Stock; and

(ii)   the per share exercise price for the Buyer Common Stock issuable upon exercise of each Unvested Company Stock Option assumed by the Buyer shall be determined by dividing the per share exercise price of Company Common Stock subject to such Unvested Company Stock Option, as in effect immediately prior to the Effective Time, by the Conversion Ratio, and rounding the resulting exercise price up to the nearest whole cent.

The “Conversion Ratio” means the quotient of Merger Consideration per Share,divided by the average of the closing sale prices of a share of Buyer Common Stock as reported on The Nasdaq National Market for each of the twenty (20) consecutive trading days immediately preceding the Closing Date; provided, however, that if, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock or Buyer Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Conversion Ratio shall be adjusted to the extent appropriate to reflect such occurrence. Any restriction on the exercise of any Unvested Company Stock Option assumed by the Buyer shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Unvested Company Stock Option shall otherwise remain unchanged as a result of the assumption of such Unvested Company Stock Option, in each case except to the extent otherwise provided in any Company Stock Plan or any stock option or other agreement between the holder of an Unvested Company Stock Option and the Company. Nothing herein shall be construed to prohibit the Buyer from adjusting the conversion described in this subsection (b) by modifying the exercise price per share of Buyer Common Stock, and taking such actions, in each case, as may be necessary or appropriate to comply with Section 409A of the Code and to preserve the intended tax treatment of the Unvested Company Stock Options.

(c)   Notification.   Within five (5) Business Days following the Effective Time, the Buyer shall deliver to the participants in the Company Stock Plans an appropriate notice setting forth such participants’ rights pursuant to the Company Stock Options, as provided in this Section 2.3.

(d)   Action by Buyer.   As soon as reasonably practicable following the date of this Agreement and in any event prior to the Effective time, the Buyer shall take all corporate action necessary to reserve for issuance under the Company Stock Plans a sufficient number of shares of Buyer Common Stock for delivery upon exercise of the Unvested Company Stock Options assumed in accordance with this Section 2.3. As soon as reasonably practicable following the Effective Time (and in any event not later than twenty (20) days after the Buyer becomes eligible to register securities on Form S-8 (or any successor form)), the Buyer shall file a registration statement on Form S-8 (or any successor form) or another appropriate form with respect to the shares of Buyer Common Stock subject to such options and shall use commercially reasonable efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options remain outstanding.

5

(e)   Action by the Company.   As soon as reasonably practicable following the date of this Agreement and in any event prior to the Effective Time, the Company Board (or, if appropriate, any committee administering the Company Stock Plans) shall adopt such resolutions or take such other actions as are required to adjust the terms of the Company Stock Options to permit the foregoing and to provide that with respect to the Company ESPP (i) participants thereunder may not increase their payroll deductions or purchase elections from those in effect on the date of this Agreement, (ii) no purchase period will be commenced after the date of this Agreement, and (iii) the amount of each participant’s accumulated contributions under the Company ESPP as of immediately prior to the Effective Time shall be refunded to such participant as promptly as practicable following the Effective Time (without interest).

(f)   Withholding Taxes, Consents Required.   All amounts payable pursuant to this Section 2.3 shall be subject to any required withholding of Taxes and shall be paid without interest.

(g)   Termination of Company ESPP.   The Company shall terminate its Amended and Restated Employee Stock Purchase Plan, as amended (the “Company ESPP”), in accordance with its terms as of or prior to the Effective Time.

2.4   Dissenting Shares.

(a)   Notwithstanding anything to the contrary contained in this Agreement, shares of Company Common Stock issued and outstanding immediately prior to the Effective Time that are held by a holder who did not vote in favor of the Merger and who is entitled to demand and has made a proper demand for appraisal of such shares of Company Common Stock in accordance with the DGCL (any such shares being referred to as “Dissenting Shares” until such time as such holder fails to perfect or otherwise loses such holder’s appraisal rights under the DGCL with respect to such shares) shall not be converted into or represent the right to receive Merger Consideration in accordance with Section 2.1, but shall be entitled only to such rights as are granted pursuant to Section 262 of the DGCL to a holder of Dissenting Shares.

(b)   If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall automatically be converted into and shall represent only the right to receive Merger Consideration in accordance with Section 2.1, without interest thereon, upon surrender of the Certificate formerly representing such shares.

(c)   The Company shall give the Buyer: (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time pursuant to the DGCL, any withdrawal of any such demand and any other demand, notice or instrument delivered to the Company pursuant to the DGCL that relate to such demand; and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. The Company shall not waive any failure by a holder of shares of Company Common Stock to timely comply with the requirements of the DGCL to perfect or demand appraisal rights pursuant to this Section 2.4 or make any payment or settlement offer prior to the Effective Time with respect to any such demand, notice or instrument unless the Buyer shall have given its written consent to such payment or settlement offer.

All of the outstanding shares of capital stock and other equity securities or interests of each Subsidiary of the Company are duly authorized, validly issued, fully paid, nonassessable and free of preemptive rights and all such shares (other than directors’ qualifying shares in the case of non-U.S. Subsidiaries, all of which the Company has the power to cause to be transferred for no or nominal consideration to the Company or the Company’s designee) are owned, of record and beneficially, by the Company or another of its Subsidiaries free and clear of all security interests, liens,

20

Company’s Knowledge have there been any attempts to organize the employees of the Company within the past three (3) years. Neither the Company nor any of its Subsidiaries is the subject of any proceeding asserting that the Company or any of its Subsidiaries has committed an unfair labor practice that, individually or in the aggregate, would reasonably be expected to have a Company Material Adverse Effect. To the Company’s Knowledge, there is no picketing pending or threatened, nor, to the Company’s Knowledge any labor strikes, disputes, walkouts, work stoppages, slow-downs or lockouts involving the Company or any of its Subsidiaries, that, individually or in the aggregate, would reasonably be expected to have a Company Material Adverse Effect.

No notice of cancellation or termination has been received by the Company or any of its Subsidiaries with respect to any of the Policies. The consummation of the transactions contemplated by this Agreement will not, in and of itself, cause the revocation, cancellation or termination of any Policy.

3.19   Opinion of Financial Advisor.   The financial advisor of the Company, Goldman Sachs, has delivered to the Company an opinion dated the date of this Agreement to the effect that, as of such date, the Merger Consideration is fair to the holders of Company Common Stock from a financial point of view, a copy of which has been provided to Buyer.

3.22   Brokers.   No agent, broker, investment banker, financial advisor or other firm or Person is or shall be entitled, as a result of any action, agreement or commitment of the Company or any of its Affiliates, to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with any of the transactions contemplated by this Agreement, except Goldman Sachs, whose fees and expenses shall be paid by the Company.

Notwithstanding anything to the contrary set forth in this Agreement, prior to receipt of the Company Stockholder Approval, (x) in response to an unsolicited, bona fide Acquisition Proposal that did not result from a breach of this Section 6.1 and that the Company Board determines in good faith (after consultation with outside counsel and its financial advisor) is, or would be reasonably likely to constitute, a Superior Proposal, and (y) if the Company Board otherwise determines in good faith (after consultation with outside counsel) that failure to do so would reasonably be likely to result in a breach by the Company’s directors of their fiduciary duties to the Company or its stockholders, and subject in each case to compliance with Section 6.1(c), the Company may, at any time prior to obtaining the Company Stockholder Approval (but in no event after obtaining the Company Stockholder Approval), after providing Buyer with not less than 48 hours’ written notice of its intention to take such actions (A) furnish information with respect to the Company to any Person (and the Representatives of such Person) making an Acquisition Proposal or an inquiry (provided, that such Person has entered into a confidentiality agreement with the Company with confidentiality provisions in favor of the Company that are not materially less favorable to the Company than the Confidentiality Agreement and that expressly permits disclosure of the identity of the bidder and the material terms of such inquiry or Acquisition Proposal), (B) engage in discussions or negotiations (including solicitation of revised Acquisition Proposals with such Person and its Representatives regarding any such Acquisition Proposal or inquiry and (C) amend, or grant a waiver or release under, any standstill or similar agreement with such Person or with Buyer.

Notwithstanding anything to the contrary set forth in this Agreement (but subject to the next sentence), the Company or the Company Board may take any action otherwise prohibited by this Section 6.1(c) if the Company Board determines in good faith, after consultation with outside counsel, that such action is necessary to comply with its fiduciary obligations under applicable Law or that failure to take such action could violate their fiduciary duties to the Company or its stockholders; provided, however, that no Company Adverse Recommendation Change may be made in response to a Superior Proposal until the third Business Day following the Company’s delivery to Buyer of written notice (unless at the time such notice is otherwise required to be given there are less than three Business Days prior to the Company Stockholders Meeting, in which case the Company shall provide as much notice as is reasonably practicable) from the Company (a “Company Adverse Recommendation Notice”) advising the Buyer that the Company Board intends to make such Company Adverse Recommendation Change and specifying the terms and conditions of such Superior Proposal (it being understood and agreed that any amendment to the financial terms or other material terms of such Superior Proposal shall require a new Company Adverse Recommendation Notice and a new three Business Day period (unless at the time such notice is otherwise required to be given there are less than three Business Days prior to the Company Stockholders Meeting, in which case the Company shall provide as much notice as is reasonably practicable)). However, the Company Board shall nevertheless not make such an Adverse Recommendation Change, unless, (x) the Company notifies the Buyer in writing at least three Business Days (or such lesser period as is reasonably practicable if less than three Business Days remain before the Company Stockholders Meeting) before taking that action, of its intention to make an Adverse Recommendation Change and attaching the most current version of any proposed agreement or a detailed summary of all material terms of any such proposal and the identity of the offeror (to the extent not prohibited by any confidentiality agreement executed by the Company prior to the date hereof), and (y) the Buyer does not propose, within three Business Days (or such lesser period as specified above) after delivery by the Company of that written notification, such adjustments to the terms and conditions of this Agreement as would enable the Company Board to proceed with its recommendation to its stockholders without an Adverse Recommendation Change.

(d)   Certain Permitted Disclosure.   Nothing contained in this Section 6.1 or in Section 6.5 (or elsewhere in this Agreement) shall prohibit the Company from (i) taking and disclosing to its stockholders a position with respect to any tender offer contemplated by Rule 14d-9 or Rule 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or (ii) making any disclosure to the Company’s stockholders if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure to make such disclosure would be inconsistent with its obligations under applicable Law or would create a material risk of a breach by the Company’s directors of their fiduciary duties to the Company’s stockholders or (iii) furnishing a copy of or excerpts from this Agreement to any third party (or its

28

representatives) that makes an Acquisition Proposal or that makes an inquiry that could lead to an Acquisition Proposal.

(e)   Cessation of Ongoing Discussions.   Promptly following the execution and delivery of this Agreement by the parties, the Company shall, and shall direct its Representatives to, cease, terminate and discontinue immediately all discussions and negotiations that commenced prior to the date of this Agreement regarding any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal.

Any such notification and report form and supplemental information shall be in substantial compliance with the requirements of, and shall request early termination of the waiting period (if applicable) under, the Antitrust Laws. The Buyer, Acquisition Sub and the Company

31

shall furnish, and shall cause their respective Affiliates to furnish, to the other such necessary information and reasonable assistance as the other may request in connection with its preparation of any filing, presentation or submission that is necessary under any applicable Antitrust Law.

For the avoidance of doubt, subject to the final proviso in the preceding sentence, each of the Company and the Buyer shall take any and all actions necessary in order to ensure that (i) no requirement for a waiver, consent or approval of the Federal Trade Commission, the Antitrust Division of the Department of Justice, any State Attorney General or other Governmental Entity, (ii) no decree, judgment, injunction, temporary restraining order or any other order in any suit or proceeding, and (iii) no other matter relating to any antitrust or competition Law or regulation would preclude consummation of the Merger by the Outside Date, provided that in the case of clauses (i) through (iii) above, the parties shall not be required to take any such action if it has received the advice of outside counsel that such action does not have a reasonable probability of success.

(d)   Except as otherwise expressly provided herein, each of the Company, the Buyer and the Acquisition Sub shall give (or shall cause their respective Subsidiaries to give) any notices to third parties, and use, and cause their respective Subsidiaries to use, their commercially reasonable efforts to obtain any third party consents, the absence of which would reasonably be expected to have a Company Material Adverse Effect or a Buyer Material Adverse Effect or to prevent the consummation of the Merger.

6.6   Public Disclosure.   Except as may be required by Law or stock market regulations, (a) the initial press release announcing the execution of this Agreement shall be jointly issued and shall be in such form as shall be mutually agreed upon by the Company and the Buyer and (b) the Buyer and the Acquisition Sub and (except in furtherance of actions permitted by Section 6.1 or as required by Law) the Company

32

shall each use its commercially reasonable efforts to consult with the other party before issuing any other press release or otherwise making any public statement with respect to the Merger or this Agreement.

6.7   Indemnification.

(a)   From and after the Effective Time, the Buyer and the Surviving Corporation shall, jointly and severally, indemnify and hold harmless each Person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of the Company or any of its Subsidiaries (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, legislative or investigative (whether internal or external), arising out of or pertaining to the fact that the Indemnified Party is or was an officer or director of the Company or any of its Subsidiaries, whether asserted or claimed prior to, at or after the Effective Time, to the full extent required or permitted by the Company’s or such Subsidiary’s certificate of incorporation, bylaws or other agreements currently in effect. Each Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of the Buyer and the Surviving Corporation within ten (10) Business Days of receipt by the Buyer or the Surviving Corporation from the Indemnified Party of a request therefor, provided that any such Indemnified Party shall have provided an undertaking, to the extent required by the DGCL, to repay such advancement if it is ultimately determined that the Indemnified Party is not entitled to be indemnified.

(b)   From and after the Effective Time, the Buyer will (and will cause the Surviving Corporation and its Subsidiaries to) fulfill and honor in all respects the obligations of the Company and its Subsidiaries pursuant to: (i) each indemnification agreement in effect between the Company or any of its Subsidiaries and any Indemnified Party; and (ii) any indemnification provision and any exculpation provision set forth in the certificate of incorporation, bylaws or other charter or organizational documents of the Company or any of its Subsidiaries as in effect on the date of this Agreement.  From the Effective Time through the sixth anniversary of the date on which the Effective Time occurs, the certificate of incorporation and bylaws of the Surviving Corporation shall contain, and Buyer shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of the Company and its Subsidiaries than are presently set forth in the certificate of incorporation and bylaws of the Company, and such provisions shall not be amended, repealed, or otherwise modified in any manner that could adversely affect the rights thereunder of any Person benefited by such provisions. If, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Party delivers to the Company, the Surviving Corporation or the Buyer, as applicable, a written notice asserting a claim for indemnification under this section, then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved.

(c)   Subject to the next sentence, the Surviving Corporation shall either (i) maintain, and the Buyer shall cause the Surviving Corporation to maintain, at no expense to the beneficiaries, in effect for six (6) years from and after the Effective Time the current policies of the directors’ and officers’ liability insurance maintained by the Company (the “Current D&O Insurance”) with respect to matters existing or occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), so long as the annual premium therefor would not be in excess of two hundred fifty percent (250%) of the last annual premium paid prior to the Effective Time (such 250%, the “Maximum Premium”), or (ii) purchase a six (6) year extended reporting period endorsement with respect to the Current D&O Insurance (a “Reporting Tail Endorsement”) and maintain such endorsement in full force and effect for its full term. If the Company’s existing insurance expires, is terminated or cancelled during such six-year period or exceeds the Maximum Premium, the Surviving Corporation shall obtain, and Buyer shall cause the Surviving Corporation to obtain, as much directors’ and officers’ liability insurance as can be obtained for the

33

remainder of such period for an annualized premium not in excess of the Maximum Premium, on terms and conditions no less advantageous to the Indemnified Parties than the Company’s existing directors’ and officers’ liability insurance. Notwithstanding anything to the contrary in this Agreement, the Company may, prior to the Effective Time, purchase a Reporting Tail Endorsement, provided that the Company does not pay more than six (6) times the last annual premium for Current D&O Insurance for such Reporting Tail Endorsement, in which case, provided that the Buyer causes the Surviving Corporation to maintain such Reporting Tail Endorsement in full force and effect for its full term, the Buyer shall be relieved from its obligations under the preceding two sentences of this Section 6.7(c).

(d)   The Buyer shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by the Persons referred to in this Section 6.7 in connection with their enforcement of their rights provided in this Section 6.7.

(e)   The provisions of this Section 6.7 are intended to be in addition to the rights otherwise available to the current officers and directors of the Company by law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives.

(f)    The Company will use commercially reasonable efforts to cause each officer or director of the Company and each of its Subsidiaries to enter into an agreement or amendment to an existing agreement providing for reasonable cooperation by such Person in connection with any present and future actual or threatened litigation, administrative proceeding or investigation involving the Company or its Subsidiaries that relates to events, occurrences or conduct occurring or claimed to have occurred during the period of such Person’s association with the Company in a form reasonably satisfactory to the Buyer.

6.8   Notification of Certain Matters.   During the Interim Period, the Buyer and the Acquisition Sub shall give prompt notice to the Company, and the Company shall give prompt notice to the Buyer and the Acquisition Sub, of (a) the occurrence, or failure to occur, of any event, which occurrence or failure to occur is reasonably likely to cause any representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect, in each case at any time from and after the date of this Agreement until the Effective Time, (b) any material failure of the Buyer and Acquisition Sub or the Company, as the case may be, or of any officer, director, employee or agent thereof, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, (c) receipt of any notice from any third party or Governmental Entity alleging that the consent of such third party or Governmental Entity is or may be required in connection with the transactions contemplated by this Agreement, (d) any material claims, actions, proceedings or governmental investigations commenced or, to its Knowledge, threatened, related to the transactions contemplated by this Agreement. Notwithstanding the above, the delivery of any notice pursuant to this Section 6.8 will not limit or otherwise affect the remedies available hereunder to the party receiving such notice or the conditions to such party’s obligation to consummate the Merger.

6.9   Exemption from Liability under Section 16(b).

(a)   The Board of Directors of the Buyer, or a committee thereof consisting of non-employee directors (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall adopt a resolution in advance of the Effective Time providing that the receipt by the Company Insiders of options to purchase Buyer Common Stock upon assumption and conversion of Company Stock Options, in each case pursuant to the transactions contemplated hereby and to the extent such securities are listed in the Section 16 Information, is intended to be exempt pursuant to Rule 16b-3 under the Exchange Act.

(b)   For purposes of this Agreement, “Section 16 Information” means information regarding the Company Insiders and the number of shares of Company Common Stock or other Company equity securities deemed to be beneficially owned by each such Company Insider and expected to be exchanged

34

for options to purchase Buyer Common Stock in connection with the Merger, which shall be provided by the Company to the Buyer at least 10 Business Days prior to the Closing. For purposes of this Agreement, “Company Insiders” means those officers and directors of the Company who immediately after the Closing become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to equity securities of the Buyer.

6.10   Employee Benefits and Service Credit.   From and after the Effective Time, the Buyer shall, or shall cause the Surviving Corporation and its Subsidiaries to, provide employees of the Buyer or the Surviving Corporation or their respective Subsidiaries who shall have been employees of the Company or any of its Subsidiaries immediately prior to the Effective Time (“Continuing Employees”), until the first anniversary of the Effective Time, health and welfare benefits that are reasonably comparable, in the aggregate, to, at the election of the Buyer, either those provided by the Company and its Subsidiaries immediately prior to the Effective Time or those provided to similarly situated employees of the Buyer and its Subsidiaries from time to time under the Buyer Employee Plans (as defined below). Following the Effective Time, the Buyer will give Continuing Employees full credit for prior service with the Company or its Subsidiaries for purposes of (w) eligibility and vesting under any Buyer Employee Plans, and (x) determination of benefit levels under any Buyer Employee Plan or policy relating to vacation or severance, in each case for which the Continuing Employees are otherwise eligible and in which the Continuing Employees are offered participation, but except where such credit would result in a duplication of benefits. In addition, the Buyer shall waive, or cause to be waived, any limitations on medical benefits relating to pre-existing conditions to the same extent such limitations are waived under any comparable plan of the Buyer and recognize for purposes of annual deductible and out-of-pocket limits under its medical and dental plans, deductible and out-of-pocket expenses paid by Continuing Employees in the calendar year in which the Effective Time occurs.

Commitment Letter, and provides for financing in an amount that, when taken together with the amount of equity provided under the Equity Commitment Letter, is not less than that provided for in the Financing as of the date of this Agreement. For the avoidance of doubt, occurrence of the Financing and/or the Buyer’s receipt of the proceeds thereof shall not be a condition precedent to the obligations of the Buyer and the Acquisition Sub to effect the Merger.

(a)   by mutual written consent of the Buyer and the Company at any time prior to the Effective Time; or

(b)   by either the Buyer or the Company if the Effective Time shall not have occurred by the first anniversary of the date of this Agreement (the “Outside Date”) (provided, that the right to terminate this Agreement under this Section 8.1(b) shall not be available to any party whose failure (or whose Subsidiary’s failure) to fulfill any obligation under this Agreement has been a principal cause of or resulted in the failure of the Effective Time to occur on or before the Outside Date, and provided further, that the passage of such period shall be tolled for up to three months during which any party shall be subject to a non-final order, decree, ruling or action restraining, enjoining or otherwise prohibiting the consummation of the Merger); or

(c)   by either the Buyer or the Company at any time prior to the Effective Time if a Governmental Entity of competent jurisdiction shall have issued a nonappealable final order, decree or ruling or taken any other nonappealable final action, in each case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger;

(e)   by the Buyer if (A) a Company Adverse Recommendation Change shall have occurred or (B) the Company Board or any committee thereof (x) shall not have rejected any Acquisition Proposal (including, for these purposes, by taking no position with respect to the acceptance by the Company’s stockholders of a tender offer or exchange offer, which shall constitute a failure to reject such Acquisition Proposal) within three Business Days after receipt of a written request from Buyer that it do so if such request is made following the making by any Person of an Acquisition Proposal or (y) shall have failed to publicly reconfirm the Company Board Recommendation within three Business Days after receipt of a written request from Buyer that it do so if such request is made following the public disclosure by any Person of an Acquisition Proposal;

(f)    by the Buyer at any time prior to the Effective Time, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, which breach or failure to perform (i) would cause the conditions set forth in Sections 7.1(d) or 7.1(e) not to be satisfied, and (ii) shall not have been cured within twenty (20) Business Days following receipt by the Company of written notice of such breach or failure to perform from the Buyer; or

(g)   by the Company, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of the Buyer or the Acquisition Sub set forth in this Agreement, which breach or failure to perform (i) would cause the conditions set forth in Sections 7.2(d) or 7.2(e) not to be satisfied, and (ii) shall not have been cured within twenty (20) Business Days following receipt by the Buyer of written notice of such breach or failure to perform from the Company.

39

immediately become void and there shall be no liability or obligation on the part of the Company, the Buyer, the Acquisition Sub or their respective officers, directors, stockholders or Affiliates; provided, that (a) any such termination shall not relieve any party from liability for any willful breach of this Agreement (including, in the case of the Buyer and the Acquisition Sub, damages based on the consideration payable to the stockholders of the Company as contemplated by this Agreement) or from liability for fraud and (b) the provisions of Sections 5.2 (Confidentiality) and 8.3 (Fees and Expenses), this Section 8.2 (Effect of Termination) and Article IX (Miscellaneous) of this Agreement and the Confidentiality Agreement shall remain in full force and effect and survive any termination of this Agreement.

8.3   Fees and Expenses.

(a)   Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees and expenses, whether or not the Merger is consummated.

(b)   In the event that:

(i)    (A) an Acquisition Proposal shall have been made known to the Company or shall have been made directly to its stockholders generally or any Person shall have publicly announced an intention (whether or not conditional or withdrawn) to make an Acquisition Proposal, and thereafter (B) this Agreement is terminated by the Company or Buyer pursuant to Section 8.1(b) or 8.1(d) and, in the case of a termination pursuant to Section 8.1(d), such Acquisition Proposal shall have been publicly disclosed or announced, and (C) the Company enters into a definitive agreement with respect to, or consummates, a transaction contemplated by any Acquisition Proposal within twelve (12) months after the date this Agreement is terminated;

(iii)  this Agreement is terminated by Buyer pursuant to Section 8.1(e); then in any such event under clause (i) or (ii), or this clause (iii) of this Section 8.3(b), the Company shall pay to Buyer a termination fee of $35.5 million in cash (the “Termination Fee”).

(c)   Any payment required to be made pursuant to clause (i) or (ii) or (iii) of Section 8.3(b) shall be made to Buyer promptly upon the earlier of the execution of a definitive agreement with respect to, or the consummation of, any transaction contemplated by a Acquisition Proposal. All such payments shall be made by wire transfer of immediately available funds to an account to be designated by the Buyer.

(d)   In the event that the Company shall fail to pay the Termination Fee required pursuant to this Section 8.3 when due, such fee shall accrue interest for the period commencing on the date such fee became past due, at a rate equal to the rate of interest publicly announced by Citibank, in the City of New York from time to time during such period, as such bank’s Prime Lending Rate plus 2%. In addition, if the Company shall fail to pay such fee when due, the Company shall also pay to the other party all of the other party’s costs and expenses (including attorneys’ fees) in connection with efforts to collect such fee. The Company acknowledges that the fee and the other provisions of this Section 8.3 are an integral part of the transactions and that, without these agreements, Buyer would not enter into this Agreement.

8.4   Amendment.   This Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters

40

presented in connection with the Merger by the stockholders of any party, but, after any such approval, no amendment shall be made which by law requires further approval by such stockholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.5   Extension; Waiver.   At any time prior to the Effective Time, except as otherwise provided, the parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. Such extension or waiver shall not apply to any time for performance, inaccuracy in any representation or warranty, or noncompliance with any agreement or condition, as the case may be, other than that which is specified in the extension or waiver. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

9.5   Assignment.   Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of Law or otherwise by any of the parties hereto without the prior written consent of the other parties, and any such assignment without such prior written consent shall be null and void. Subject to the preceding sentence, this Agreement shall

42

be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.

In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.
