thereto, and such other documents as may be reasonably required by the Exchange Agent, the holder of such Company Certificate shall be entitled to receive in exchange therefor certificates representing that number of whole Parent Shares, if any, into which the number of Company Shares previously represented by such Company Certificates shall have been converted pursuant to Section 3.1 and any cash, distributions or dividends required to be paid pursuant to Sections 3.2(d) and (e) below, and Company Certificates so surrendered shall be forthwith canceled. The Exchange Agent shall promptly accept such Company Certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. No interest shall accrue on the Merger Consideration (or the cash payable as described in Sections 3.2(d) and (e) below) payable upon the surrender of Company Certificates for the benefit of, or be paid to, the holders of Company Certificates.

(d) No dividends or other distributions with respect to Parent Shares shall be paid to the holder of any unsurrendered Company Certificate with respect to the Parent Shares represented thereby by reason of the conversion of Company Shares pursuant to Section 3.1, and no cash payment in lieu of fractional Parent Shares shall be paid to any such holder pursuant to Section 3.2(e) until such Company Certificate is surrendered in accordance with this Article III. Subject to the effect of applicable Laws, following surrender of any such Company Certificate, there shall be paid, without interest, to the Person in whose name the Parent Shares representing such securities are registered (i) at the time of such surrender, the amount of any cash payable in lieu of fractional Parent Shares to which such holder is entitled pursuant to Section 3.2(e) and the proportionate amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to Parent Shares issued upon conversion of Company Shares, and (ii) at the appropriate payment date or as promptly as practicable thereafter, the proportionate amount of dividends or other distributions, with (x) a record date with respect thereto after the Effective Time, but prior to such surrender, and (y) a payment date subsequent to such surrender, payable with respect to such Parent Shares.

(e) Notwithstanding any other provision hereof, no fraction of a Parent Share will be issued and no dividend or other distribution, stock split or interest with respect to Parent Shares shall relate to any fractional Parent Share, and such fractional interest shall not entitle the owner thereof to vote or to any rights as a security holder of the Parent Shares. In lieu of any such fractional security, each holder of shares of Company Shares otherwise entitled to a fraction of a Parent Share in accordance with the provisions of this Article III will be entitled to receive from the Exchange Agent a cash payment in an amount equal to the product of (i) such fractional part of a Parent Share multiplied by (ii) the 20-Day Parent VWAP Price.

(f) All Merger Consideration delivered upon the surrender of Company Certificates in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to Company Shares theretofore represented by such Company Certificates. Until surrendered as contemplated by this Section 3.2, each Company Certificate shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration into

which Company Shares theretofore represented by such Company Certificate shall have been converted pursuant to this Article III. No interest will be paid or will accrue on the cash payable upon the surrender of any Company Certificate.

(g) At the Effective Time, 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 Company Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Company Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article III.

(h) If any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed and, if required by the Exchange Agent, the posting by such Person of a bond or other surety in such amount as the Exchange Agent may reasonably direct as indemnity against any claim that may be made with respect to such Company Certificate and subject to such other reasonable conditions as the Exchange Agent may impose, the Exchange Agent shall deliver in exchange for such Company Certificate the Merger Consideration into which Company Shares theretofore represented by such Company Certificate shall have been converted pursuant to this Article III.

(i) If any payment under this Article III is to be made to a Person other than the Person in whose name any Company Certificate surrendered in exchange therefor is registered, it shall be a condition of payment that the Company Certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer and that the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of Company Certificate surrendered or such Person shall establish to the satisfaction of the Surviving Corporation that such Tax has been paid or is not applicable.

(j) The Exchange Agent shall invest any funds held by it for purposes of this Section 3.2 as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent.

(k) Parent and/or the Exchange Agent shall be entitled to deduct and withhold from the consideration or other amounts otherwise payable pursuant to this Agreement (in whatever form) to the holders of Company Shares an amount equal to the amounts, if any, required to be deducted or withheld under any provision of U.S. federal Tax Law, or any provision of state, local or foreign Tax Law, with respect to the making of such payment. Amounts so withheld shall promptly be paid to the appropriate Tax authority and shall be treated for all purposes of this Agreement as having been paid to the holders of Company Shares in respect of which such deduction or withholding was made.

(l) None of Parent, Merger Sub, the Company or the Exchange Agent shall be liable to any Person in respect of any Parent Shares (or dividends or distributions

with respect thereto) or cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. Any Parent Shares or portion of the cash that has been made available to the Exchange Agent pursuant to this Section 3.2 that remains unclaimed by the holder of any Company Certificate six (6) months after the Effective Time, shall be returned to Parent and any such holder who has not exchanged such holder’s Company Certificate prior to such time shall thereafter look only to Parent for any claim for Merger Consideration, any cash in lieu of fractional shares of Parent Shares to which they are entitled pursuant to Section 3.2(e) and any dividends or other distributions with respect to Parent Shares to which they are entitled pursuant to Section 3.2(d) hereunder.

Section 3.3 Company Stock Options/Warrants.

(a) Company Stock Options. Each Company Option, whether vested or unvested, that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, cease to represent a right to acquire Company Shares and shall automatically be converted into an option (a “Company Converted Option”) to purchase Parent Shares. The number of Parent Shares subject to each Company Converted Option shall be equal to the product of the number of Company Shares subject to such Company Option multiplied by the Exchange Ratio; provided that any fractional Parent Shares resulting from such multiplication shall be rounded down to the nearest whole share. The exercise price per share of each Company Converted Option shall equal the quotient of the exercise price per share under the corresponding Company Option divided by the Exchange Ratio; provided that such exercise price shall be rounded up to the nearest whole cent. Each such Company Converted Option will otherwise have substantially the same terms and conditions as the corresponding Company Option, including vesting and term of exercise. The Company agrees to take all actions necessary, if any, to effectuate the provisions of this Section 3.3. Notwithstanding anything in this Agreement to the contrary, the conversion of options under this Section 3.3 shall be made in a manner so as to preserve as nearly as possible any exemption from Section 409A a Company Option may have and/or any status as an “incentive stock option” a Company Option may have immediately prior to the Effective Time.

(b) Company Warrants. Each warrant to purchase Company Shares (a “Company Warrant”) that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, cease to represent a right to acquire Company Shares and shall automatically be converted into a warrant (a “Company Converted Warrant”) to purchase Parent Shares. The number of Parent Shares subject to each Company Converted Warrant shall be equal to the product of the number of Company Shares subject to such Company Warrant multiplied by the Exchange Ratio; provided that any fractional Parent Shares resulting from such multiplication shall be rounded down to the nearest whole share. The purchase price per share of each Company Converted Warrant shall equal the quotient of the purchase price per share under the corresponding Company Warrant divided by the Exchange Ratio; provided that such purchase price shall be rounded up to the nearest whole cent. Each such Company Converted Warrant will otherwise have substantially the same terms and conditions as the corresponding Company Warrant, including the term of exercise.

The Company Options have been properly accounted for by the Company in accordance with GAAP.

(c) All Pension Plans have been and continue to be the subject of favorable (through any applicable remedial amendment period) determination letters from the IRS, or a timely application therefor has been filed, to the effect that such Pension Plans are qualified and exempt from federal income taxes under Section 401(a) and 501(a), respectively, of the Code, and no such determination letter has been revoked nor has any such Pension Plan been amended since the date of its most recent determination letter or application therefor in any respect that would adversely affect its qualification or materially increase its costs; and no circumstances exist and no events have occurred that would reasonably be expected to adversely affect the qualification of any Pension Plan or the related trust after taking into account the availability of applicable remedial action programs.

(h) All contributions or premiums owed by the Company or any of its Subsidiaries with respect to Benefit Plans under law, contract or otherwise have been made in full and on a timely basis in all material respects and the Company or its Subsidiaries are not obligated to contribute with respect to any such Benefit Plan that involves a material retroactive contribution, assessment or funding waiver arrangement. All administrative costs attributable to Benefit Plans have been paid when due.

(j) There are no pending or, to the Company’s Knowledge, threatened, claims, lawsuits, arbitrations or audits asserted or instituted against any Benefit Plan, any fiduciary (as defined by Section 3(21) of ERISA) thereto, the Company, any of its Subsidiaries or any employee or administrator thereof in connection with the existence, operation or administration of a any Benefit Plan, other than routine claims for benefits.

The Company has

delivered or made available to Parent the current base salary and target bonus with respect to each “disqualified individual” of the Company (as defined under Section 280G(c) of the Code).

(l) No amounts payable under any of the Benefit Plans or any other contract, agreement or arrangement with respect to which the Company or any of its Subsidiaries may have any liability that was intended to constitute “performance-based compensation” for the purposes of section 162(m)(4)(C) of the Code would reasonably be expected to fail to be deductible for federal income tax purposes by virtue of section 162(m) of the Code.

(m) Neither the Company nor its Subsidiaries is a party to any collective bargaining agreement. There are no material threatened or pending controversies, strikes, work stoppages, slowdowns, lockouts, arbitrations or other material labor disputes pending or, to the Knowledge of the Company, threatened between the Company or its Subsidiaries and any representatives of any of their employees.

(o) The Company and each Subsidiary has in all material respects properly classified the employment or other service status of all employees or other persons providing services to or on behalf of the Company or any of its Subsidiaries for purposes of (i) all applicable law and, (ii) if applicable, the terms or tax qualification requirements of any Benefit Plan or other benefit arrangement.

Section 4.11 Contracts.

(a) Neither the Company nor any of its Subsidiaries or, to the Knowledge of the Company, any other party, is in violation or is in material breach of or in default under (nor does there exist any condition which the passage of time or the giving of notice would result in such a violation or breach of, or constitute such a default or other condition under) any Company Contract to which it is a party. No other party to any such

(a) Neither the Board of Directors of Parent nor any committee thereof shall withdraw (or modify in a manner adverse to the Company), or propose to withdraw (or modify in a manner adverse to the Company), the approval, recommendation or declaration of advisability by such Board of Directors or any such committee thereof of this Agreement, the Merger or the other transactions contemplated by this Agreement, including the issuance of Parent Shares in connection with the Merger (any action described in this sentence being referred to as a “Parent Adverse Recommendation Change”). Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Parent Stockholder Approval, the Board of Directors of Parent or any committee thereof may make a Parent Adverse Recommendation Change in response to a material change in circumstances after the date of this Agreement if such Board of Directors or committee thereof determines in good faith (after consultation with outside counsel) that it is required to do so in order to comply with its fiduciary duties to the stockholders of Parent under applicable Law; provided, however, that (i) no Parent Adverse Recommendation Change shall be made until after the second (2^nd) Business Day following the Company’s receipt of written notice from Parent advising the Company that the Board of Directors of Parent or committee thereof intends to take such action and specifying the reasons therefor, including description of the material change in circumstances in reasonable detail, (ii) during such two (2) Business Day period Parent shall negotiate with the Company in good faith to make such adjustments to the terms and conditions of this Agreement as would enable Parent to proceed with its recommendation of this Agreement and not make a Parent Adverse Recommendation Change and (iii) Parent shall not make a Parent Adverse Recommendation Change if, prior to the expiration of such two (2) Business Day period, the Company makes a binding, written proposal (contingent only on the Board of Directors of Parent not making a Parent Adverse Recommendation Change) to adjust the terms and conditions of this Agreement such that the Board of Directors of Parent or committee thereof would no longer be required to make a Parent Adverse Recommendation Change.

Without limiting the generality of the foregoing, the Company’s obligations pursuant to the first sentence of this Section 6.4(a) shall not be affected by (i) the commencement, public proposal, public disclosure or communication to the Company of any Takeover Proposal or (ii) any Company Adverse Recommendation Change; provided, however, that no breach of this Section 6.4(a) shall be deemed to have occurred if the Company adjourns or postpones the Company Stockholders Meeting for a reasonable period of time, each such period of time not to exceed ten (10) Business Days; provided that (x) at the time of such adjournment or postponement the Board of Directors

shall be prohibited by the terms of this Agreement from making a Company Adverse Recommendation Change, and the Company Stockholders Meeting is then scheduled to occur within three (3) Business Days of the time of such adjournment or postponement or (y) at the time the Board of Directors announces a Company Adverse Recommendation Change, the Company Stockholders Meeting is then scheduled to occur no later than ten (10) Business Days from the date of such Company Adverse Recommendation Change; provided further that the Company may not adjourn or postpone the Company Stockholders Meeting pursuant to this clause (ii) more than two (2) times or for more than fifteen (15) Business Days in the aggregate.

(b) Parent shall, as promptly as practicable following the effectiveness of the Form S-4, establish a record date for, duly call, give notice of, convene and hold the Parent Stockholder Meeting.

(d) As promptly as practicable after the execution of this Agreement, (i) Parent and the Company shall prepare and shall cause to be filed with the SEC a Joint proxy statement (together with any amendments thereof or supplements thereto, the “Joint Proxy Statement/Prospectus”) relating to the Company Stockholder Meeting and the Parent Stockholder Meeting and (ii) Parent shall prepare and shall cause to be filed with the SEC a registration statement on Form S-4 (together with all amendments thereto, the “Form S-4”) in which the Joint Proxy Statement/Prospectus shall be included as a prospectus, in connection with the registration under the Securities Act of the Parent Shares to be issued to the stockholders of the Company pursuant to the Merger. Each of the Company and Parent shall cooperate and provide the other with reasonable opportunity to review and comment on the Form S-4 and Joint Proxy Statement/Prospectus and any amendment or supplement thereto prior to filing such document with the SEC. Each of Parent and the Company shall use reasonable efforts to cause the Form S-4 to become effective as promptly as practicable after the execution of this Agreement, and, prior to the effective date of the Form S-4, Parent shall use reasonable efforts to take all or any action required under any applicable federal or state securities Laws in connection with the issuance of Parent Shares pursuant to the Merger. Each of Parent and the Company shall furnish all information concerning it as may reasonably be requested by the other party in connection with such actions and the preparation of the Joint Proxy Statement/Prospectus and the Form S-4. As promptly as practicable after the Form S-4 shall have become effective, each of the Company and Parent shall mail the Joint Proxy Statement/Prospectus to its respective stockholders. Each of Parent and the Company shall also promptly file, use all of their respective reasonable efforts to cause to become effective as promptly as practicable and, if required, mail to the Company’s and Parent’s stockholders, any amendment to the Form S-4 or Joint Proxy Statement/Prospectus which may become necessary after the date the Form S-4 is declared effective.

(e) No amendment or supplement to the Joint Proxy Statement/Prospectus or the Form S-4 will be made by Parent or the Company without the approval of the other party, which shall not be unreasonably withheld or delayed. Each of Parent and the Company will advise the other, promptly after it receives notice thereof, of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Shares issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Joint Proxy Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information. If at any time prior to the Effective Time any information relating to either party, or any of their respective Affiliates, officers or directors should be discovered by the Company or Parent, that should be set forth in an amendment or supplement to the Form S-4 or the Joint Proxy Statement/Prospectus, so that either of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other party hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law or regulation, disseminated to the Company’s and Parent’s stockholders.

Section 6.5 Access to Information. The Company and Parent shall, and shall cause each of its Subsidiaries to, afford to the other party and its officers, employees, accountants, counsel, agents and other Representatives reasonable access upon reasonable advance notice and during reasonable business hours (in a manner that does not disrupt or interfere with business operations) to such properties, personnel, books and records of such party and its Subsidiaries (including Tax Returns filed and those in preparation, workpapers and other items relating to Taxes) as the other party shall reasonably request, and shall furnish promptly all information concerning the business, properties and personnel of such party and its Subsidiaries as the other party may reasonably request. All such information shall be kept confidential in accordance with the terms of the Confidentiality Agreement; provided that no information or Knowledge obtained by Parent or the Company in any investigation conducted pursuant to this Section 6.5 shall affect or be deemed to modify any representation or warranty of the other party set forth herein or the conditions to the consummation of the transaction contemplated hereby.

Section 6.6 Notification of Certain Matters. The Company shall use reasonable efforts to give prompt notice to Parent, and Parent shall use reasonable efforts to give prompt notice to the Company, of (a) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, has caused any representation or warranty made by such party contained in this Agreement to be untrue such that the condition with respect to such party’s representations set forth in Section 7.2(a) or Section 7.3(a), as applicable, would not be satisfied and (b) any Company Material Adverse Effect or Parent Material Adverse Effect or the occurrence of any event or events which could be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect or a Parent Material Adverse Effect; provided, however, that the delivery of any notice pursuant to this

Section 6.6 shall not be considered in determining whether any representation or warranty is true for purposes of Article VII; provided, further, that the failure to deliver any notice pursuant to this Section 6.6 shall not be considered in determining whether the condition set forth in Section 7.2(b) or Section 7.3(b) has been satisfied or any related termination right in Article VIII is available.

Section 6.7 Reasonable Efforts.

(a) Subject to the other terms of this Agreement, each of the parties hereto shall use reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable under applicable Laws and regulations to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement as promptly as practicable, including (i) the preparation and filing of all forms, registrations and notices required to be filed to consummate the transactions contemplated by this Agreement and the taking of such reasonable actions as are necessary to obtain any requisite approvals, consents, orders, exemptions or waivers by any third party or Governmental Entity, including filings pursuant to the HSR Act and (ii) using reasonable efforts to cause the satisfaction of all conditions to Closing. Each party shall promptly consult with the other with respect to, provide any necessary information with respect to and provide the other (or its counsel) copies of, all filings made by such party with any Governmental Entity or any other information supplied by such party to a Governmental Entity in connection with this Agreement and the transactions contemplated by this Agreement; provided, however, that nothing in this Section 6.7 shall require or be construed to require Parent to offer or agree to enter into any agreements, including agreements to sell, license or otherwise dispose of, or hold separate or otherwise divest itself of, all or any portion of Parent’s businesses or assets or any portion of the businesses or assets of any of its Subsidiaries or any portion of the businesses or assets of the Company or any of its Subsidiaries or agreeing to any limitations or restrictions on its conduct in order for the Closing to occur.

(b) Each party hereto shall promptly inform the others of any communication from any Governmental Entity regarding any of the transactions contemplated by this Agreement. If any party or Affiliate thereof receives a request for additional information or documentary material from any such Governmental Entity with respect to the transactions contemplated by this Agreement, then such party will endeavor in good faith to make, or cause to be made, as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request. Nothing herein shall require any party to waive any substantial rights or agree to any substantial limitation on its (or the Surviving Corporation’s) operations or to dispose of any assets.

Section 6.8 State Takeover Statutes. The Company and its Board of Directors shall (a) take all reasonable action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to this Agreement, or the transactions contemplated by this Agreement and (b) if any state takeover statute or similar statute becomes applicable to this Agreement or the transaction contemplated by

this Agreement, take all reasonable action necessary to ensure that the 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 or the transactions contemplated by this Agreement.

Section 6.9 Indemnification, Exculpation and Insurance.

(a) From and after the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) indemnify, defend and hold harmless, and advance expenses to, the individuals who at or prior to the Effective Time were directors or officers of the Company or any of its Subsidiaries (collectively, the “Indemnitees”) with respect to all acts or omissions by them in their capacities as such at any time prior to the Effective Time, to the fullest extent required by: (i) certificate of incorporation or bylaws (or comparable charter or organizational documents) of the Company or any of its Subsidiaries as in effect on the date of this Agreement; and (ii) any applicable contract which has been disclosed to Parent at or prior to the date hereof and as in effect on the date of this Agreement or, with respect to persons who become directors or officers of the Company or any of its Subsidiaries after the date hereof and prior to the Closing, which is entered into and disclosed to Parent after the date hereof and which is in the form and substance of the agreements that have been disclosed to Parent at or prior to the date hereof.

(b) For six (6) years after the Effective Time, Parent shall provide directors and officers liability insurance covering acts or omissions occurring prior to the Effective Time with respect to those Indemnitees who are covered by the Company’s and its Subsidiaries’ directors’ and officers’ liability insurance policies as of the Closing on terms with respect to such coverage and amount no less favorable in the aggregate than the Company’s and its Subsidiaries’ current directors’ and officers’ liability insurance policies; provided, however, that if the aggregate annual premiums for such insurance at any time during such period shall exceed two hundred percent (200%) of the per annum rate of premium paid by the Company as of the date hereof for such insurance, then Parent shall provide only such coverage as shall then be available at an annual premium equal to two hundred percent (200%) of such rate.

(c) This Section 6.9 shall survive the consummation of the Merger and shall be binding on all successors and assigns of Parent and the Surviving Corporation. The Indemnitees to whom this Section 6.9 applies shall be third party beneficiaries of this Section 6.9. The provisions of this Section 6.9 are intended to be for the benefit of each Indemnitee, his or her heirs and his or her representatives.

Section 6.12 Affiliates. Not less than ten (10) Business Days prior to the date of the Company Stockholder Meeting, the Company shall deliver to Parent a letter identifying all Persons who, in the judgment of the Company, may be deemed at the time this Agreement is submitted for adoption by the stockholders of the Company, “affiliates” of the Company for purposes of Rule 145 under the Securities Act and applicable SEC rules and regulations, and such list shall be updated as necessary to reflect changes from the date thereof. The Company shall use its reasonable efforts to cause each Person identified on such list to deliver to Parent not later than five (5) Business Days prior to the Effective Time, a written agreement substantially in the form attached as Exhibit A hereto.

Section 6.13 Employee Benefits; Options.

(a) For a period of at least one (1) year following the Effective Time (such period of time, the “Protected Period”), Parent shall cause the Surviving Corporation or any of its Affiliates to provide to employees of the Company and its Subsidiaries with benefits which are comparable in the aggregate to those provided to similarly situated employees of Parent. Notwithstanding anything set forth above, the participation of the employees of the Company or its Subsidiaries in any Parent’s option or similar equity grant or purchase programs or plans shall be subject to the eligibility requirements of such programs or plans.

(b) Employees of the Company and its Subsidiaries as of the Closing shall be provided credit for all service with the Company and its Subsidiaries, to the same extent as such service was credited for such purpose by the Company and its Subsidiaries for such employees, under: (i) all employee benefit plans, programs, policies and fringe benefits to be provided to such employees for purposes of eligibility and vesting (but not benefit accrual); (ii) severance plans, programs and policies to be provided to such employees for purposes of calculating the amount of each such employee’s severance benefits; and (iii) vacation and sick leave plans, programs and policies for purposes of calculating the amount of each such employee’s vacation and sick leave.

(c) Notwithstanding anything in this Agreement to the contrary, nothing in this Section 6.13 shall impede or limit Parent, Merger Sub, the Company or any of their Affiliates from terminating any of their employees at any time for any reason or no reason, subject to the provisions of applicable Law and applicable Contracts.

(d) As promptly as practicable but no later than fifteen (15) Business Days after the Effective Time, Parent shall file with the SEC a registration statement on Form S-8 covering the sale of Parent Stock issuable pursuant to outstanding Company Options assumed by Parent pursuant to the terms hereof, and Parent shall use reasonable efforts to maintain the effectiveness of such registration statement so long as any assumed Company Options remain outstanding. The Company will cooperate and reasonably assist Parent in the preparation of such registration statement.

(e) No provision of this Section 6.13 shall create any third-party beneficiary rights in any Company Employee, any beneficiary or dependent thereof with respect to the compensation, terms and conditions of employment and/or benefits that may be provided to any Company Employee by Parent, the Surviving Corporation or any of their Subsidiaries under any benefit plan which they may maintain.

Section 6.14 Tax Covenants.

(a) The Company shall prepare and timely file or cause to be prepared and timely filed, in accordance with applicable Law and (provided consistent therewith) past practice, all Tax Returns (whether separate or consolidated, combined, group or unitary Tax Returns that include the Company or any of its Subsidiaries) that are required to be filed (with extensions) on or before the Closing Date; provided, however, that the Company shall deliver substantively complete, final drafts of all income Tax Returns to Parent at least fifteen (15) days prior to the due date thereof and shall not file any such Tax Return without obtaining the prior written consent of Parent (such consent not to be unreasonably withheld or delayed); it being understood that the Company shall not be deemed in breach of this covenant by reason of a failure to timely file a Tax Return (if the Company shall have provided Parent with the required draft of such Tax Return at least fifteen (15) days prior to the filing deadline) if such failure to timely file is due to Parent having unreasonably withheld or delayed its consent to the filing of the Tax Return in question or due to a reasonable, good faith disagreement between the Parent and the Company with respect to the reporting of an item on such Tax Return not resolved by the filing deadline.

(b) Except as otherwise directed by Parent in writing at least five (5) days prior to the Closing Date, all contracts, agreements, arrangements, or intercompany account systems under which the Company or any of its Subsidiaries may at any time have an obligation to indemnify for or share the payment of or liability for any portion of a Tax or any amount calculated with reference to any portion of a Tax (other than customary agreements to indemnify lessors, licensors, lenders and debt securityholders in respect of Taxes none of which involves any material financial exposure) shall be terminated with respect to the Company and each such Subsidiary on or prior to the

Closing Date, and the Company and each such Subsidiary shall thereafter be released from any liability thereunder.

(c) Without the written consent of Parent, which consent shall not be unreasonably withheld or delayed, the Company shall not, and shall not permit any of its Subsidiaries to, do any of the following: (i) make, change or revoke any election in respect of Taxes, (ii) file any amended Tax Return, (iii) adopt or change any accounting method or period in respect of Taxes, (iv) enter into any closing agreement, (v) settle any claim or assessment in respect of Taxes, (vi) change any practice with respect to Taxes, (vii) consent to any extension or waiver of any statute of limitations applicable to any claim or assessment in respect of Taxes or (viii) offer or agree to do any of the foregoing or surrender its rights to do any of the foregoing or to claim any refund in respect of Taxes.

(d) Parent and Company intend that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Each of Parent, Merger Sub and the Company agrees that it will not take (and will cause its Subsidiaries not to take) any action, or fail to take (or allow any Subsidiary to fail to take) any action, which action or failure to take action would reasonably be expected to cause the Merger not to so qualify. Each of Parent and the Company shall use all reasonable efforts to obtain the Tax opinions referred to in Section 7.2(i) and Section 7.3(e), respectively.

Section 6.15 Parent Board of Directors. Effective as of the Effective Time, the size of the Board of Directors of Parent shall be increased from eight (8) to ten (10) members and two (2) individuals selected by the Board of Directors of Parent and agreed to by the Company, consistent with the policies of Parent’s corporate governance committee, shall be appointed as independent directors of Parent.

Section 6.16 Lock-up Agreements. The Person listed on Section 6.16 of the Company Disclosure Schedule shall enter into a lock-up agreement in the form attached as Exhibit B hereto, pursuant to which, among other things, such Person shall agree not to sell, assign or otherwise transfer the Parent Shares such Person receives pursuant to the terms of this Agreement from the Closing Date until six (6) months after the Closing Date.

Each such representation letter shall be dated on or before the date of such opinion and shall not have been withdrawn or modified in any material respect. If Parent

has not received such an opinion from Dewey Ballantine LLP, but Cooley Godward Kronish LLP is willing to provide an opinion to Parent, in form and substance reasonably satisfactory to Parent, based on facts, representations and assumptions set forth in such opinion that are consistent with the state of facts existing at the Effective Time, dated as of the Effective Time, to the effect that the Merger will qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of section 368(a) of the Code, the delivery of such an opinion by Cooley Godward Kronish LLP shall be sufficient to cause this condition to be satisfied.
