Section 7.02 Company Stockholders’ Meeting. The Company shall take all lawful action to call, give notice of, convene and, after the commencement of the mailing of the Proxy Statement to the Company’s stockholders, hold the Company Stockholders’ Meeting as promptly as practicable for the purpose of obtaining the Company Stockholder Approval. Unless this Agreement is validly terminated in accordance with Section 9.01, the Company agrees that this Agreement shall be submitted for adoption by the stockholders of the Company at the Company Stockholders’ Meeting and the obligation of the Company to call, give notice of,

Subject to Section 7.03(d), the Company shall solicit from its stockholders proxies in favor of the adoption of this Agreement. Unless this Agreement is validly terminated in accordance with Section 9.01, the Company agrees that it shall not submit to a vote of the stockholders of the Company any Competing Transaction or Competing Transaction Agreement (in either case, whether or not a Superior Proposal) prior to the vote of the Company’s stockholders regarding the adoption of this Agreement at the Company Stockholders’ Meeting. Parent may request on one occasion that the Company Stockholders’ Meeting be postponed or adjourned for up to 15 Business Days (but in any event no later than the Outside Date), (x) in order to solicit additional proxies for the purpose of obtaining the Company Stockholder Approval (unless prior to such adjournment the Company shall have received an aggregate number of proxies voting for the adoption of this Agreement, which have not been withdrawn, such that the condition in Section 8.01(b) will be satisfied at such meeting), (y) if a quorum is not present or (z) in order to allow reasonable additional time for (1) the filing and mailing of, at the reasonable request of Parent, any supplemental or amended disclosure and (2) such supplemental or amended disclosure to be disseminated to, and reviewed by, the stockholders of the Company prior to the Company Stockholders’ Meeting, in which event the Company shall cause the Company Stockholders’ Meeting to be postponed or adjourned in accordance with Parent’s request.

Section 7.03 No Solicitation of Transactions. (a) The Company agrees that neither it nor any of its Subsidiaries nor any of their respective Representatives will, and that it will cause each of its Subsidiaries and each of its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) solicit, initiate or encourage (including by way of furnishing nonpublic information), or take any other action to facilitate, any inquiries or the making of any proposal or offer (including any proposal or offer to the Company’s stockholders) with respect to any Competing Transaction, (ii) enter into, maintain, continue or otherwise engage or participate in any discussions or negotiations with any Person or entity in furtherance of such inquiries or to obtain a proposal or offer with respect to a Competing Transaction, (iii) agree to, approve, endorse, recommend or consummate any Competing Transaction, (iv) enter into any Competing Transaction Agreement, (v) take any action to approve a third party becoming an “interested stockholder”, or to approve any transaction, for purposes of Section 203 of the DGCL or (vi) resolve, propose or agree, or authorize or permit any Representative, to do any of the foregoing. Except as explicitly permitted by this Section 7.03, the Company acknowledges and agrees that the doing of any of the foregoing by any of its Subsidiaries or any Representative of the Company or any of its Subsidiaries shall be deemed to be a breach by the Company of this Section 7.03. The Company shall, and shall cause its Subsidiaries and its and its Subsidiaries’ Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Persons conducted prior to the execution of this Agreement by the Company, any of its Subsidiaries or its or any of their Representatives with respect to a Competing Transaction. The Company shall not, and shall not permit any Subsidiary of the Company to, release any third party from, or waive any provision of, any confidentiality or standstill agreement to which it is a party and the Company shall, to the extent possible, promptly use commercially reasonable efforts to take all steps necessary to terminate or cause to

be terminated any such waiver previously granted with respect to any provision of any such confidentiality or standstill agreement; provided, that, the Company Board shall not be required to take any action with respect to standstill agreements that would be inconsistent with the fiduciary duties of the members of the Company Board to the Company and its stockholders under applicable Law. The Company shall promptly request each Person that has, in the past 18 months, executed a confidentiality agreement in connection with such Person’s consideration of acquiring (whether by merger, acquisition of stock or assets or otherwise) the Company or any of its Subsidiaries, to return (or if permitted by the applicable confidentiality agreement, destroy) all information required to be returned (or, if applicable, destroyed) by such Person under the terms of the applicable confidentiality agreement and, if requested by Parent, to enforce such Person’s obligation to do so.

(b) The Company shall promptly (and in any event within 24 hours after the Company attains knowledge thereof) notify Parent, orally and in writing, after the receipt by the Company, any or its Subsidiaries or any of their respective Representatives of any proposal, inquiry, offer or request (or any amendment thereto) with respect to either a Competing Transaction or an IP Transaction and including any request for discussions or negotiations and any request for information relating to the Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries, in each case, with respect to a Competing Transaction or an IP Transaction. Such notice shall indicate the identity of the Person making such proposal, inquiry, offer or request and, to the extent such proposal, inquiry, offer or request (or any amendment thereto) is oral, a description of such proposal, inquiry, offer or request, including the terms and conditions (if any) of such proposed Competing Transaction or IP Transaction, and the Company shall promptly (and in any event within 24 hours after receipt by the Company) provide to Parent copies of any written materials received by the Company in connection with any of the foregoing. The Company agrees that it shall keep Parent reasonably informed of the status and material details of (including discussions with respect to or amendments or proposed amendments to) (i) any such proposal, inquiry, offer or request and (ii) any information requested of or provided by the Company pursuant to Section 7.03(c). To the extent practicable, the Company shall provide Parent with notice of any meeting of the Company Board at which the Company Board is reasonably expected to consider any proposal, inquiry, offer or request with respect thereto (or any lesser advance notice otherwise provided to members of the Company Board in respect of such meeting), which notice may be provided on the same day that notice is provided to the Company Board of such meeting. The Company agrees that it shall simultaneously provide to Parent any nonpublic information concerning the Company that may be made available pursuant to Section 7.03(c) to any other Person in response to any such proposal, inquiry, offer or request (or any amendment thereto) to the extent that the Company has not made such information previously available to Parent.

(c) Notwithstanding anything to the contrary in this Section 7.03 (except as explicitly permitted by Section 7.03(b)), at any time prior to the receipt of the Company Stockholder Approval, the Company may furnish information to, and enter into discussions with, a Person who has made an unsolicited, written, bona fide proposal or offer with respect to a Competing Transaction that did not arise or result from any breach of this Section 7.03 if, prior to furnishing such information and entering into such discussions, the Company Board has (i) determined, in its good faith judgment (after having received the advice of outside legal counsel) (A) that such proposal or offer constitutes, or may reasonably be expected to lead to, a

Superior Proposal and (B) that the failure to furnish such information to, or enter into such discussions with, the Person who made such proposal or offer would be inconsistent with the Company Board’s fiduciary duties to the Company’s stockholders under applicable Law, (ii) provided written notice to Parent of its intent to furnish information or enter into discussions with such Person, which notice may be provided on the same day that the Company takes such action, and (iii) obtained from such Person an Acceptable Confidentiality Agreement (it being understood that an Acceptable Confidentiality Agreement and any related agreements shall not include any provision granting such Person exclusive rights to negotiate with the Company or having the effect of prohibiting the Company from satisfying its obligations under this Agreement) and, immediately upon its execution, delivered to Parent a copy of such Acceptable Confidentiality Agreement.

(d) Except as set forth in this Section 7.03(d), neither the Company Board nor any committee thereof shall (i) withdraw, qualify, modify, amend or fail to make, or propose publicly to withdraw, qualify, modify or amend the Company Recommendation or (ii) make any public statement inconsistent with the Company Recommendation (any of the actions described in clauses (i) or (ii), a “Change in the Company Recommendation”). Notwithstanding the foregoing, at any time prior to the receipt of the Company Stockholder Approval, in response to a Superior Proposal that did not arise or result from any breach of this Section 7.03 or an Intervening Event, the Company Board may make a Change in the Company Recommendation if the Company Board determines in its good faith judgment (after having received the advice of outside legal counsel) that, in light of such Superior Proposal or Intervening Event, the failure of the Company Board to make a Change in the Company Recommendation would be inconsistent with the fiduciary duties of the members of the Company Board to the Company and its stockholders under applicable Law; provided, however, that the Company shall not be entitled to exercise its right to make a Change in the Company Recommendation pursuant to this Section 7.03(d) unless:

(1)

in connection with a Superior Proposal:

(A) prior to giving effect to clauses (B) through (D) below, the Company Board shall have determined, in its good faith judgment (after having received the advice of outside legal counsel) that such unsolicited, written, bona fide proposal or offer with respect to a Competing Transaction that did not arise or result from any breach of this Section 7.03 constitutes, or may reasonably be expected to lead to, a Superior Proposal;

(B) the Company shall have provided to Parent the notice relating to such Competing Transaction in accordance with Section 7.03(b);

(C) the Company has provided written notice to Parent (a “Notice of Change in the Company Recommendation”), stating that the Company Board intends to make a Change in the Company Recommendation and the manner in which it intends (or may intend) to do so, at least four Business Days prior to making any Change in the Company Recommendation; and

(D) Parent does not, within four Business Days of receipt of the Notice of Change in the Company Recommendation (the “Notice Period”), make an offer or proposal to revise the terms of this Agreement, including by increasing or modifying the Merger Consideration (any such offer, a “Revised Transaction Proposal”), in a manner that the Company Board determines in its good faith judgment, after having received the advice of outside legal counsel, is on such terms and conditions that the failure of the Company Board to make a Change in the Company Recommendation would no longer be inconsistent with the Company Board’s fiduciary duties to the Company and its stockholders under applicable Law; provided, however, that during the Notice Period the Company shall negotiate in good faith with Parent (to the extent Parent desires to negotiate) regarding any Revised Transaction Proposal provided, further, that any amendment to the terms of a Superior Proposal during the Notice Period shall require a new written notice of the terms of such amended Superior Proposal from the Company and an additional Notice Period of two Business Days (instead of four Business Days) that otherwise satisfies this Section 7.03(d)(1)(D).

(2)

in connection with an Intervening Event:

(A) the Company has provided a Notice of Change in the Company Recommendation, stating that the Company Board intends to make a Change in the Company Recommendation and the manner in which it intends (or may intend) to do so, describing the applicable material fact, event, change, development or set of circumstances giving rise to the Intervening Event, at least four Business Days prior to making any Change in the Company Recommendation;

(B) Parent does not, within the Notice Period, make a Revised Transaction Proposal, in a manner that the Company Board determines in its good faith judgment, after having received the advice of outside legal counsel, is on such terms and conditions that the failure of the Company Board to make a Change in the Company Recommendation would no longer be inconsistent with the Company Board’s fiduciary duties to the Company and its stockholders under applicable Law; provided, however, that during the Notice Period the Company shall negotiate in good faith with Parent (to the extent Parent desires to negotiate) regarding any Revised Transaction Proposal.

(e) Any disclosure that the Company Board is required to make with respect to the receipt of a proposal or offer with respect to a Competing Transaction, an Intervening Event or otherwise consistent with its fiduciary duties to the Company and its stockholders under applicable Law or Rule 14d-9 or with Rule 14e-2(a) promulgated under the Exchange Act will

not constitute a violation of this Section 7.03; provided, however, that neither the Company Board nor any committee thereof shall make a Change in the Company Recommendation in connection with such disclosure (it being understood that any “stop, look and listen” communication by or on behalf of the Company pursuant to Rule 14d-9(f) shall not be considered a Change in the Company Recommendation). Any Change in the Company Recommendation shall not change the approval of the Company Board for purposes of causing any state takeover statute or other state Law to be inapplicable to the Transactions.

Section 7.04 Access to Information; Confidentiality. (a) Except as otherwise prohibited by applicable Law or the terms of any contract or agreement to which the Company or any of its Subsidiaries is subject (provided that the Company shall use its reasonable best efforts to promptly obtain any consent required under such contract or agreement in order that it may comply with the terms of this Section 7.04(a), from the date of this Agreement until the Effective Time, the Company shall, and shall cause its Subsidiaries to, (i) provide to Parent and Parent’s Representatives access at reasonable times upon reasonable prior notice to the officers, employees, agents, properties, offices and other facilities of the Company and its Subsidiaries and to the books and records thereof; and (ii) furnish promptly to Parent such information concerning the business, properties, contracts, assets, liabilities, personnel and other aspects of the Company and its Subsidiaries as Parent or its Representatives may reasonably request.

(b) All information obtained by the parties pursuant to this Section 7.04 shall be kept confidential in accordance with the Confidentiality Agreement.

(c) No investigation pursuant to this Section 7.04 shall affect any representation, warranty, covenant or agreement in this Agreement of any party hereto or any condition to the obligations of the parties hereto.

(d) The Company hereby waives compliance by Parent, Merger Sub, or any of their respective Affiliates, of the standstill obligations under the Confidentiality Agreement with respect to this Agreement and the Merger contemplated hereby.

Section 7.05 Employee Benefits Matters. (a) From and after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries to honor in accordance with their terms, all contracts, agreements, arrangements, policies, plans and commitments of the Company and its Subsidiaries as in effect immediately prior to the Effective Time that are applicable to any current or former employees or directors of the Company or any Subsidiary of the Company; provided that nothing herein shall prohibit Parent or the Surviving Corporation and its Subsidiaries from, with respect to any such contract, agreement, arrangement, policy, plan or commitment, (i) terminating it in accordance with its terms or (ii) replacing it with a similar contract, agreement, arrangement policy, plan or commitment of Parent, as applicable. With respect to any employees of the Company or any Subsidiary of the Company as of the date of this Agreement who remain employed by the Surviving Corporation or any of its Subsidiaries immediately following the Closing Date, during the six month period following the Closing Date, Parent shall cause the Surviving Corporation and its Subsidiaries to honor the severance arrangements set forth in Section 7.05 of the Company Disclosure Schedule applicable to such employees. Employees of the Company or any Subsidiary of the Company shall receive credit for purposes of eligibility to participate and vesting under any employee benefit plan, program or

arrangement established or maintained by the Surviving Corporation or any of its Subsidiaries for service accrued or deemed accrued prior to the Effective Time with the Company or any Subsidiary of the Company; provided, however, that such crediting of service shall not operate to duplicate any benefit or the funding of any such benefit. In addition, Parent shall waive, or cause to be waived, any limitations on benefits relating to any pre-existing conditions to the extent such conditions are covered immediately prior to the Effective Time under the applicable Plans and to the same extent such limitations are waived under any comparable plan of Parent or its Subsidiaries and use commercially reasonable efforts to 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 employees of the Company and its Subsidiaries in the calendar year in which the Effective Time occurs. The parties agree that nothing in this Section 7.05, whether express or implied, is intended to create any third party beneficiary rights in any Service Provider and that all provisions in this Section 7.05 are included for the sole benefit of the parties to this Agreement and shall not create any right in any other person, including any current or former Service Providers, any participant in any Plan or any beneficiary of a Plan.

(b) On or prior to the date that is ten (10) business days prior to the Closing Date, Parent may request that the Company take all necessary action to terminate the World Heart 401(k) Savings & Investment Plan (the “401(k) Plan”) effective as of no later than the day immediately preceding the Closing Date. In event that Parent makes such request, (i) the Company shall provide Parent with evidence reasonably acceptable to Parent that the 401(k) Plan has been terminated effective as of no later than the day immediately preceding the Closing Date pursuant to resolutions of the Company Board and (ii) Parent shall use its reasonable best efforts to take all steps necessary to permit each employee of the Company or one of its Subsidiaries who has received an eligible rollover distribution (as defined in Section 402(c)(4) of the Code) from the 401(k) Plan, if any, to roll such eligible rollover distribution as part of any lump sum distribution to the extent permitted by the 401(k) Plan into an account under Parent’s 401(k) plan to the extent permitted by Parent’s 401(k) Plan.

(c) COBRA. The Company will not continue to offer a group health plan to employees after the Closing and, accordingly, Parent shall be solely responsible for providing, or causing an Affiliate of Parent to provide, continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, to those individuals who are M&A qualified beneficiaries (as defined in Treasury Regulation Section 54.4980B-9, Q&A-4(a)) with respect to the transactions contemplated by this Agreement (collectively, the “M&A Qualified Beneficiaries”). The Company shall provide all necessary or appropriate information for Parent to offer continuation coverage to such M&A Qualified Beneficiaries.

Section 7.06 Directors’ and Officers’ Indemnification and Insurance. (a) Parent and the Surviving Corporation agree that all rights to indemnification existing in favor of the current or former directors, officers, employees, fiduciaries or agents of the Company or any of its Subsidiaries as provided in the respective charter, by-laws or other organizational documents or in any indemnification agreement as in effect on the date of this Agreement for acts or omissions occurring prior to the Effective Time shall be assumed and performed by the Surviving Corporation and shall continue in full force and effect for not less than six years following the Effective Time, except as otherwise required by Law. If any claims for indemnification are asserted within such period, all rights to indemnification in respect of such

claims shall continue until final disposition of such claims. Without limiting the scope of the foregoing, the certificate of incorporation of the Surviving Corporation shall contain provisions no less favorable with respect to indemnification than are set forth in Article VI of the certificate of incorporation of the Company and Article XI of the bylaws of the Company, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were directors, officers, employees, fiduciaries or agents of the Company, unless such modification shall be required by Law.

(b) The Surviving Corporation shall use its reasonable best efforts to maintain in effect for six years from the Effective Time, if available, the current directors’ and officers’ liability insurance policies maintained by the Company (except the Surviving Corporation may substitute therefor policies of at least the same coverage containing terms and conditions that are not materially less favorable to the Persons covered by such policies maintained by the Company) with respect to matters occurring prior to the Effective Time; provided, however, that in no event shall the Surviving Corporation be required to expend pursuant to this Section 7.06(b) an annual amount in excess of 100% of the annual premiums currently paid by the Company (which current amount is set forth in Section 7.06 of the Company Disclosure Schedule) for such insurance; provided, further, that, if the amount of the annual premiums necessary to maintain or procure such insurance coverage exceeds such maximum amount, the Surviving Corporation shall maintain or procure, for such six-year period, the most advantageous policies of directors’ and officers’ insurance obtainable for an annual premium equal to that maximum amount.

(c) The Surviving Corporation’s obligations under Section 7.06(b) may be satisfied, with the approval of Parent, by the Company purchasing a “tail” policy from an insurance carrier with substantially the same or better credit rating as the current carrier for the Company’s existing directors’ and officers’ insurance policy, which (i) has an effective term of six years from the Effective Time, (ii) covers each Person covered by the Company’s directors’ and officers’ insurance policy in effect on the date of this Agreement or at the Effective Time for actions and omissions occurring prior to the Effective Time, and (iii) contains terms and conditions that are no less favorable to the persons covered by such policies maintained by the Company than those of the Company’s directors’ and officers’ insurance policy in effect on the date of this Agreement; provided, however, that the amount paid by the Company shall not be in excess of 150% of the annual premiums currently paid by the Company (which current amount is set forth in Section 7.06 of the Company Disclosure Schedule) for such insurance. If such “tail” prepaid policies have been obtained by the Company prior to the Effective Time, the Surviving Corporation shall maintain such policies in full force and effect, for their full respective terms, and continue to honor its respective obligations thereunder.

(d) In the event the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation, as the case may be, or at Parent’s option, Parent, shall assume the obligations set forth in this Section 7.06. This Section 7.06 may not be amended, altered or repealed after the Effective Time without the prior written consent of the affected Persons.

Section 7.07 Notification of Certain Matters. (a) The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (i) the occurrence, or non-occurrence, of any event which could reasonably be expected to cause any of their respective representations or warranties contained in this Agreement to become untrue or inaccurate such that the conditions set forth in Section 8.02(a) or Section 8.03(a), as applicable, would not be satisfied and (ii) any failure of the Company, Parent or Merger Sub, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement such that the conditions set forth in Section 8.02(a) or Section 8.03(b), as applicable, would not be satisfied; provided, however, that the delivery of any notice pursuant to this Section 7.07 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

(b) The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (i) any notice or other written communication from any Governmental Authority in connection with the Transactions or from any Person alleging that the consent of such Person is or may be required in connection with the Transactions and (ii) any Action commenced or, to its knowledge, threatened in writing, relating to or involving or otherwise affecting it or any of its Subsidiaries which, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to Article IV or Article V, as applicable, or which relates to the consummation of the Transactions.

Section 7.08 Commercially Reasonable Efforts; Further Action. (a) Each party hereto shall use commercially reasonable efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws or otherwise to consummate and make effective the Transactions, including using commercially reasonable best efforts to obtain, or cause to be obtained, all permits, consents, approvals, authorizations, qualifications and Orders of all Governmental Authorities and officials and parties to contracts with the Company and the Subsidiaries that may be or become necessary for the performance of the obligations of such party hereto pursuant to this Agreement and the consummation of the Transactions and will cooperate fully with the other parties in promptly seeking to obtain all such permits, consents, approvals, authorizations, qualifications and Orders.

(b) Each of the parties hereto agrees to cooperate and use commercially reasonable efforts to vigorously contest and resist any Action, including any administrative or judicial Action, and to have vacated, lifted, reversed or overturned any Order (whether temporary, preliminary or permanent) that is in effect and that restricts, prevents or prohibits consummation of the Transactions, including by vigorously pursuing all available avenues of administrative and judicial appeal.

Section 7.09 Plan of Reorganization. (a) Unless Parent exercises the Parent Cash Election, this Agreement is intended to constitute a “plan of reorganization” within the meaning of Section 1.368-2(g) of the income Tax regulations promulgated under the Code. From and after the date of this Agreement and until the earlier of the Effective Time and the date of Parent’s exercise of the Parent Cash Election, each party hereto shall use its reasonable best

efforts to cause the Merger to qualify, and will not knowingly take any action, cause or permit any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act could prevent the Merger from qualifying, as a “reorganization” within the meaning of Section 368(a) of the Code. Following the Effective Time, unless Parent has exercised the Parent Cash Election, none of the Surviving Corporation, Parent nor any of their Affiliates shall knowingly take any action, cause or permit any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act could cause the Merger to fail to qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

(b) Parent and the Company shall cooperate and use their respective reasonable best efforts (unless Parent exercises the Parent Cash Election) in order for (i) Parent to obtain the opinion of Shearman & Sterling LLP, in form and substance reasonably acceptable to Parent, dated as of the Closing Date, and (ii) the Company to obtain the opinion of Cooley LLP (the “Cooley Opinion”), in form and substance reasonably acceptable to the Company, dated as of the Closing Date, each to the effect that, on the basis of the facts, representations and assumptions set forth or referred to in such opinion, for United States federal income Tax purposes, the Merger will constitute a “reorganization” within the meaning of Section 368(a) of the Code and that each of Parent, Merger Sub and the Company will be a party to the reorganization within the meaning of Section 368(b) of the Code. As a condition precedent to the rendering of such opinions, Parent and the Company shall, as of the Closing Date, execute and deliver to Shearman & Sterling LLP and Cooley LLP Tax Representation Letters. Parent and the Company shall, as of the date for filing the Registration Statement (unless Parent exercises the Parent Cash Election), execute and deliver to Shearman & Sterling LLP and Cooley LLP Tax Representation Letters, dated and executed as of the applicable filing date.

(c) As of the date hereof, the Company does not know of any reason (i) why it would not be able to deliver to counsel to the Company and Parent the Tax Representation Letters at the applicable times set forth in Section 7.09(b) or (ii) why counsel to the Company and Parent would not be able to deliver the opinions contemplated by Section 7.09(b).

(d) As of the date hereof, Parent does not know of any reason (i) why it would not be able to deliver to counsel to the Company and Parent the Tax Representation Letters at the applicable times set forth in Section 7.09(b) or (ii) why counsel to the Company and Parent would not be able to deliver the opinions contemplated by Section 7.09(b).

Section 7.10 Obligations of Merger Sub. Parent shall take all action necessary to cause Merger Sub to perform its obligations under this Agreement and to consummate the Merger on the terms and subject to the conditions set forth in this Agreement.

Section 7.11 Consents of Accountants. Parent and the Company will each use their respective commercially reasonable efforts to cause to be delivered to each other consents from their respective independent auditors, in form reasonably satisfactory to the recipient and customary in scope and substance for consents delivered by independent public accountants in connection with the Registration Statement, unless Parent exercises the Parent Cash Election.

Section 7.12 Listing of Shares of Parent Common Stock. Unless Parent exercises the Parent Cash Election, Parent shall use its reasonable best efforts to cause the shares

of Parent Common Stock to be issued in the Merger to be approved for listing on NASDAQ, subject to official notice of issuance, and the Company shall cooperate with Parent with respect to such listing.

Section 7.13 Public Announcements. The initial press release relating to this Agreement shall be a joint press release the text of which has been agreed to by each of Parent and the Company. Thereafter, unless otherwise required by applicable Law or the requirements of NASDAQ, each of Parent and the Company shall each use its reasonable best efforts to consult with the other before issuing any press release or otherwise making any public statements with respect to this Agreement, the Merger or any of the other Transactions; provided, however, that this Section 7.13 shall terminate upon a Change in the Company Recommendation; provided, further, that each of Parent and the Company may make public statements in response to specific questions by the press, analysts, investors or those attending industry conferences or financial analyst conference calls, so long as any such statements are not materially inconsistent with previous press releases, public disclosures or public statements made jointly by Parent and the Company and do not reveal material, nonpublic information regarding the other party.

Section 7.14 Transfer Taxes. The Company and Parent shall cooperate in the preparation, execution and filing of all Tax Returns or other documents regarding any Transfer Taxes. All Transfer Taxes shall be paid by the Company and expressly shall not be a liability of any holder of Shares.

Section 7.15 Section 16 Matters. Prior to the Effective Time, each of Parent and the Company shall use all reasonable efforts, including in accordance with the interpretive guidance set forth by the SEC, to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) or acquisitions of Parent Common Stock (including derivative securities with respect to Parent Common Stock) resulting from the Transactions by each officer or director who is or will be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 7.16 Stockholder Litigation. The Company shall give Parent and its Representatives the opportunity to consult with the Company in connection with the defense or settlement of any stockholders litigation against the Company or its directors relating to the Transactions.

Section 10.03 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by virtue of any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

Section 10.04 Entire Agreement; Assignment. This Agreement (including the exhibits and schedules hereto and including the Company Disclosure Schedule), the Voting Agreements and the Confidentiality Agreement constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof and thereof. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties, in whole or in part (whether pursuant to a merger, by operation of Law or otherwise), without the prior written consent of the other parties, except that Parent and Merger Sub may assign all or any of their rights and obligations under this Agreement to any Affiliate of Parent, provided that (i) no such assignment shall relieve the assigning party of its obligations under this Agreement if such assignee does not perform such obligations and (ii) such assignment would not reasonably be expected to cause the Merger to fail to qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

Section 10.05 Parties in Interest. This Agreement shall be binding upon, inure solely to the benefit of, and be enforceable by, only the parties hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 7.06 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons).

Section 10.06 Specific Performance. The parties hereto agree that the parties hereto would be irreparably damaged if any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached.

Section 10.07 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware. All actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in the Court of Chancery of the State of Delaware. The parties hereto hereby (a) submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (b) irrevocably waive, and agree not to assert by way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts.

Section 10.08 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission or pdf) in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 10.09 Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the Transactions. Each of the parties hereto (a) certifies that no Representative of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.09.
