(ii)    subject to Section 2.5(c), each share of Company Capital Stock outstanding immediately prior to the Effective Time (excluding shares to be

21

canceled pursuant to Section 2.5(a)(i) and excluding Dissenting Shares) shall be converted solely into the right to receive a number of shares of Aspen Common Stock equal to the Exchange Ratio (the “Merger Consideration”).

(b)    If any shares of Company Capital Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option or a risk of forfeiture under any applicable restricted stock purchase agreement or other similar agreement with the Company, then the shares of Aspen Common Stock issued in exchange for such shares of Company Capital Stock at the Effective Time will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and certificates (if any) representing such shares of Aspen Common Stock shall accordingly be marked with appropriate legends. The Company shall use its commercially reasonable efforts to take all actions that may be reasonably necessary to ensure that, from and after the Effective Time, Aspen is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement.

(e)    Each share of common stock, $0.01 par value per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, $0.01 par value per share, of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall, as of the Effective Time, evidence ownership of such shares of common stock of the Surviving Corporation.

2.6    Contingent Value Right

(a)    Holders of Aspen Common Stock of record as of immediately prior to the Effective Time (for the avoidance of doubt, not including the PIPE Investors) shall be entitled to one contractual contingent value right (a “CVR”) issued by Aspen subject to and in accordance with the terms and conditions of the CVR Agreement, attached hereto as Exhibit E (the “CVR

22

Agreement”), for each share of Aspen Common Stock held by such holders. Notwithstanding anything herein to the contrary, the Parties shall be entitled to modify the CVR Agreement, prior to the execution thereof, to accommodate any reasonable comments by the Rights Agent.

No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Capital Stock outstanding immediately prior to the Effective Time (a “Company Stock Certificate”) is presented to the Exchange Agent or to the Surviving Corporation, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Sections 2.5 and 2.8.

2.8    Surrender of Certificates.

(a)    On or prior to the Closing Date, the Parties shall agree upon and select a reputable bank, transfer agent or trust company to act as exchange agent in the Merger (the “Exchange Agent”). At the Effective Time, Aspen shall deposit with the Exchange Agent evidence of book-entry shares representing the shares of Aspen Common Stock issuable pursuant to Section 2.5(a) in exchange for shares of Company Capital Stock. The Aspen Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.”

(b)    Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of shares of Company Capital Stock that were converted into the right to receive the Merger Consideration: (i) a letter of transmittal in customary form and containing such provisions as Aspen may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent) and (ii) instructions for effecting the surrender of Company Stock Certificates in exchange for book-entry shares of Aspen Common Stock. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be

23

reasonably required by the Exchange Agent or Aspen: (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor book-entry shares representing the Merger Consideration (in a number of whole shares of Aspen Common Stock) that such holder has the right to receive pursuant to the provisions of Section 2.5(a); and (B) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 2.8(b), each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive book-entry shares of Aspen Common Stock representing the Merger Consideration. If any Company Stock Certificate shall have been lost, stolen or destroyed, Aspen may, in its reasonable discretion and as a condition precedent to the delivery of any shares of Aspen Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an applicable affidavit with respect to such Company Stock Certificate that includes an obligation of such owner to indemnify Aspen against any claim suffered by Aspen related to the lost, stolen or destroyed Company Stock Certificate as Aspen may reasonably request. In the event of a transfer of ownership of a Company Stock Certificate that is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a Person other than the Person in whose name such Company Stock Certificate so surrendered is registered if such Company Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the transfer or establish to the reasonable satisfaction of Aspen that such Taxes have been paid or are not applicable.

(c)    No dividends or other distributions declared or made with respect to Aspen Common Stock with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Aspen Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or provides an affidavit of loss or destruction in lieu thereof in accordance with this Section 2.8 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar Laws, to receive all such dividends and distributions, without interest).

(d)    Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date that is one year after the Closing Date shall be delivered to Aspen upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 2.8 shall thereafter look only to Aspen for satisfaction of their claims for Aspen Common Stock, and any dividends or distributions with respect to shares of Aspen Common Stock.

(e)    Each of the Exchange Agent, Aspen and the Surviving Corporation shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement such amounts as are required to be deducted or withheld from such consideration under the Code or under any other applicable Law. To the extent such amounts are so deducted or withheld, and remitted to the appropriate Tax authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f)    No Party shall be liable to any holder of any Company Stock Certificate or to any other Person with respect to any shares of Aspen Common Stock (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property Law, escheat Law or similar Law.

24

2.9    Calculation of Net Cash.

(a)    No later than the Determination Date, Aspen will deliver to the Company a schedule (the “Net Cash Schedule”) setting forth, in reasonable detail, Aspen’s good faith, estimated calculation of Net Cash (the “Net Cash Calculation” and the date of delivery of such schedule being the “Delivery Date”) as of the close of business on the last Business Day prior to the Anticipated Closing Date (the “Cash Determination Time”) prepared and certified by Aspen’s Chief Financial Officer. Aspen shall make available to the Company, as reasonably requested by the Company, the work papers and back-up materials used or useful in preparing the Net Cash Schedule and, if reasonably requested by the Company, Aspen’s accountants and counsel at reasonable times and upon reasonable notice. The Net Cash Calculation shall include Aspen’s determination, as of the Cash Determination Time, of the defined terms in Section 1.1(a) necessary to calculate the Exchange Ratio.

(b)    No later than three (3) days after the Delivery Date (the last day of such period, the “Response Date”), the Company shall have the right to dispute any part of the Net Cash Calculation by delivering a written notice to that effect to Aspen (a “Dispute Notice”). Any Dispute Notice shall identify in reasonable detail and to the extent known the nature and amounts of any proposed revisions to the Net Cash Calculation and will be accompanied by reasonably detailed materials supporting the basis for such revisions.

(c)    If, on or prior to the Response Date, the Company notifies Aspen in writing that it has no objections to the Net Cash Calculation or, if on the Response Date, the Company fails to deliver a Dispute Notice as provided in Section 2.9(b), then the Net Cash Calculation as set forth in the Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Cash Determination Time for purposes of this Agreement.

(d)    If the Company delivers a Dispute Notice on or prior to the Response Date, then Representatives of Aspen and the Company shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Net Cash, which agreed upon Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Cash Determination Time for purposes of this Agreement.

(e)    If Representatives of Aspen and the Company are unable to negotiate an agreed-upon determination of Net Cash as of the Cash Determination Time pursuant to Section 2.9(d) within three days after delivery of the Dispute Notice (or such other period as Aspen and the Company may mutually agree upon), then any remaining disagreements as to the calculation of Net Cash shall be referred to an independent auditor of recognized national standing jointly selected by Aspen and the Company. If the parties are unable to select an independent auditor within five (5) days, then either Aspen or the Company may thereafter request that the Boston, Massachusetts Office of the American Arbitration Association (“AAA”) make such selection (either the independent auditor jointly selected by both parties or such independent auditor selected by the AAA, the “Accounting Firm”). Aspen and the Company shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the Net Cash Schedule and the Dispute Notice, and Aspen and the Company shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within five (5) Business Days of accepting its selection. Aspen and the Company shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of a Representative of each of Aspen and the Company. The determination of the Accounting Firm shall be limited to the disagreements

25

submitted to the Accounting Firm. The determination of the amount of Net Cash made by the Accounting Firm shall be made in writing delivered to each of Aspen and the Company, shall be final and binding on Aspen and the Company and shall (absent manifest error) be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Cash Determination Time for purposes of this Agreement. The Parties shall delay the Closing until the resolution of the matters described in this Section 2.9(e). The fees and expenses of the Accounting Firm shall be allocated between Aspen and the Company in the same proportion that the disputed amount of the Net Cash that was unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Net Cash amount. If this Section 2.9(e) applies as to the determination of the Net Cash at the Cash Determination Time described in Section 2.9(a), upon resolution of the matter in accordance with this Section 2.9(e), the Parties shall not be required to determine Net Cash again even though the Closing Date may occur later than the Anticipated Closing Date, except that either Aspen and the Company may request a redetermination of Net Cash if the Closing Date is more than 30 days after the Anticipated Closing Date.

2.10    Appraisal Rights.

(a)    Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who have exercised and perfected appraisal rights for such shares of Company Capital Stock in accordance with the DGCL or Chapter 13 of California Law (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration described in Section 2.5 attributable to such Dissenting Shares. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Company Capital Stock held by them in accordance with the DGCL or California Law, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL or California Law. All Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have effectively withdrawn or lost their right to appraisal of such shares of Company Capital Stock under the DGCL or California Law (whether occurring before, at or after the Effective Time) shall thereupon be deemed to be converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest, attributable to such Dissenting Shares upon their surrender in the manner provided in Section 2.5.

(b)    The Company shall give Aspen prompt written notice of any demands by dissenting stockholders received by the Company, withdrawals of such demands and any other instruments served on the Company and any material correspondence received by the Company in connection with such demands, and the Company shall have the right to direct all negotiations and proceedings with respect to such demands; provided that Aspen shall have the right to participate in such negotiations and proceedings. The Company shall not, without Aspen’s prior written consent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

2.11     Further Action.

5.3    Access and Investigation.

(a)    Subject to the terms of the Confidentiality Agreement, which the Parties agree will continue in full force following the date of this Agreement, during the Pre-Closing Period, upon reasonable notice, Aspen, on the one hand, and the Company, on the other hand, shall and shall use commercially reasonable efforts to cause such Party’s Representatives to: (a) provide the other Party and such other Party’s Representatives with reasonable access during normal business hours to such Party’s Representatives, personnel and assets and to all existing books, records, Tax Returns, work papers and other documents and information relating to such Party and its Subsidiaries, (b) provide the other Party and such other Party’s Representatives with such copies of the existing books, records, Tax Returns, work papers, product data, and other documents and information relating to such Party and its Subsidiaries, and with such additional financial, operating and other data and information regarding such Party and its Subsidiaries as

Any investigation conducted by either Aspen or the Company pursuant to this Section 5.3 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the other Party. The Company shall use reasonable best efforts to work in good faith to satisfy the covenants set forth in Section 5.3(a) of the Company Disclosure Schedule. Notwithstanding the foregoing, satisfying such covenants shall in no event be a condition to Closing nor shall the failure to satisfy such covenants prior to the Closing Date be a breach of this Agreement or constitute a Company Material Adverse Effect.

(b)    Notwithstanding anything herein to the contrary in this Section 5.3, no access or examination contemplated by this Section 5.3 shall be permitted to the extent that it would require any Party or its Subsidiaries to waive the attorney-client privilege or attorney work product privilege, or violate any applicable Law; provided, that such Party or its Subsidiary (i) shall be entitled to withhold only such information that may not be provided without causing such violation or waiver, (ii) shall provide to the other Party all related information that may be provided without causing such violation or waiver (including, to the extent permitted, redacted versions of any such information) and (iii) shall enter into such effective and appropriate joint-defense agreements or other protective arrangements as may be reasonably requested by the other Party in order that all such information may be provided to the other Party without causing such violation or waiver.

5.4    No Solicitation.

(a)    Aspen agrees that, during the Pre-Closing Period, neither it nor any of its Subsidiaries shall, nor shall it or any of its Subsidiaries authorize any of its Representatives to, directly or indirectly: (i) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry, (ii) furnish any non-public information regarding Aspen to any Person in connection with or in response to an Acquisition Proposal or Acquisition Inquiry, (iii) engage in discussions (other than to inform any Person of the existence of the provisions contained in this Section 5.4) or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry, (iv) approve, endorse or recommend any Acquisition Proposal (subject to Section 6.2 and Section 6.3), (v) execute or enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition Transaction or (vi) publicly propose to do any of the foregoing; provided, however, that, notwithstanding anything contained in this Section 5.4 and subject to compliance with this Section 5.4, prior to the approval of this Agreement by Aspen’s stockholders (i.e., the Required Aspen Stockholder Vote in the case of Aspen), Aspen may furnish non-public information regarding Aspen and its Subsidiaries to, and enter into discussions or negotiations with, any Person in response to a bona fide written Acquisition Proposal by such Person which Aspen’s board of directors determines in good faith, after consultation with Aspen’s outside financial advisors and outside legal counsel, constitutes, or is reasonably likely to result in, a Superior Offer (and is not withdrawn) if: (A) neither Aspen nor any Representative of Aspen shall have breached this Section 5.4 in any material respect, (B) the board of directors of Aspen concludes in good faith based on the advice of outside legal counsel, that the failure to take such action would reasonably be likely to violate the board of directors’ fiduciary duties under applicable Law, (C) at least two (2) Business Days prior to initially furnishing any such nonpublic information to, or entering into discussions with, such Person,

69

Aspen gives the Company written notice of the identity of such Person and of Aspen’s intention to furnish nonpublic information to, or enter into discussions with, such Person, (D) Aspen receives from such Person an executed Acceptable Confidentiality Agreement and (E) substantially contemporaneously with furnishing any such nonpublic information to such Person, Aspen furnishes such nonpublic information to the Company (to the extent such information has not been previously furnished by Aspen to the Company). Without limiting the generality of the foregoing, Aspen acknowledges and agrees that, in the event any Representative of Aspen takes any action that, if taken by Aspen, would constitute a breach of this Section 5.4, the taking of such action by such Representative shall be deemed to constitute a breach of this Section 5.4 by Aspen for purposes of this Agreement.

(b)    If any Party or any Representative of such Party receives an Acquisition Proposal or Acquisition Inquiry at any time during the Pre-Closing Period, then such Party shall promptly (and in no event later than one (1) Business Day after such Party becomes aware of such Acquisition Proposal or Acquisition Inquiry) advise the other Party orally and in writing of such Acquisition Proposal or Acquisition Inquiry (including the identity of the Person making or submitting such Acquisition Proposal or Acquisition Inquiry, and the material terms thereof). Such Party shall keep the other Party reasonably informed with respect to the status and material terms of any such Acquisition Proposal or Acquisition Inquiry and any material modification thereto.

(c)    During the Pre-Closing Period, the Company shall not, and the Company shall cause each of its Affiliates and its or their Representatives not to, directly or indirectly: (a) solicit, initiate, seek, encourage, promote or support, any inquiry, proposal or offer from, furnish any information regarding the Company or any of its Subsidiaries to, or participate in any discussions or negotiations with, any third party regarding, or in a manner intended or reasonably likely to facilitate, any Acquisition Proposal or Acquisition Inquiry; (b) disclose any information not customarily disclosed to any person concerning the business, properties, assets or technologies of the Company or any of its Subsidiaries, or afford to any Person access to their respective properties, assets, technologies, books or records, not customarily afforded such access; (c) assist or cooperate with any person to make any inquiry, offer, proposal or indication of interest regarding any Acquisition Proposal or Acquisition Inquiry; or (d) enter into any Contract with any person providing for an Acquisition Proposal or Acquisition Inquiry.

(d)    Each Party shall immediately cease and cause to be terminated any existing discussions, negotiations and communications with any Person that relate to any Acquisition Proposal or Acquisition Inquiry as of the date of this Agreement and request the destruction or return of any nonpublic information provided to such Person.

5.5    Notification of Certain Matters. During the Pre-Closing Period, each of the Company, on the one hand, and Aspen, on the other hand, shall promptly notify the other (and, if in writing, furnish copies of) if any of the following occurs: (a) any notice or other communication is received from any Person alleging that the Consent of such Person is or may be required in connection with any of the Contemplated Transactions, (b) any Legal Proceeding against or involving or otherwise affecting such Party or its Subsidiaries is commenced, or, to the Knowledge of such Party, threatened against such Party or, to the Knowledge of such Party, any director, officer or Key Employee of such Party, (c) such Party becomes aware of any inaccuracy in any representation or warranty made by such Party in this Agreement or (d) the failure of such Party to comply with any covenant or obligation of such Party; in each case that could reasonably be expected to make the timely satisfaction of any of the conditions set forth in Sections 7, 8 and 9, as applicable, impossible or materially less likely. No such notice shall be deemed to supplement

70

or amend the Company Disclosure Schedule or the Aspen Disclosure Schedule for the purpose of (x) determining the accuracy of any of the representations and warranties made by the Company in this Agreement or (y) determining whether any condition set forth in Section 7, 8 or 9 has been satisfied. Any failure by either Party to provide notice pursuant to this Section 5.5 shall not be deemed to be a breach for purposes of Section 8.2 or 9.2, as applicable, unless such failure to provide such notice was knowing and intentional.

Section 6. Additional Agreements of the Parties.

6.1    Proxy Statement.

(a)    As promptly as practicable after the date of this Agreement, Aspen shall prepare and file with the SEC a proxy statement relating to the Aspen Stockholder Meeting to be held in connection with the Merger and the PIPE Investment (together with any amendments thereof or supplements thereto, the “Proxy Statement”). Each of the Parties shall furnish all information concerning itself and their Affiliates, as applicable, to the other Parties as the other Parties may reasonably request in connection with such actions and the preparation of the Proxy Statement. Aspen shall promptly respond to any SEC comments on the Proxy Statement, but in no event shall Aspen take longer than 20 Business Days to respond.

(b)    Aspen (i) shall permit the Company and its counsel to review and comment on the Proxy Statement and all exhibits, amendments or supplements thereto (or other related documents); (ii) shall consider any such comments in good faith and shall accept all reasonable additions, deletions or changes suggested by the Company and its counsel in connection therewith; and (iii) shall not file the Proxy Statement or any exhibit, amendment or supplement thereto without the prior written consent of the Company, not to be unreasonably withheld, conditioned or delayed. As promptly as practicable after receipt thereof, Aspen shall provide to the Company and its counsel notice and a copy of all correspondence (or, to the extent such correspondence is oral, a summary thereof), including any comments from the SEC or its staff, between Aspen or any of its representatives, on the one hand, and the SEC, or its staff or other government officials, on the other hand, with respect to the Proxy Statement, and, in each case, shall consult with the Company and its counsel concerning any such correspondence. Aspen shall not file any response letters to any comments from the SEC without the prior written consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed. Aspen will advise the Company, promptly after it receives notice thereof, of the time when the Proxy Statement or any amendment or supplement thereto has been filed with the SEC and the time when all SEC comments to the Proxy Statement have been cleared.

(c)    Aspen and the Company shall comply with all applicable provisions of and rules under the Securities Act and Exchange Act and all applicable Laws of the State of Delaware and Nasdaq, in the preparation, filing and distribution of the Proxy Statement (or any amendment or supplement thereto), as applicable, the solicitation of proxies under the Proxy Statement and the calling and holding of Aspen Stockholder Meeting. Aspen covenants and agrees that the Proxy Statement (or any amendment or supplement thereto) will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. The Company covenants and agrees that the information supplied by or on behalf of the Company or its Subsidiaries to Aspen for inclusion in the Proxy Statement (including the Company Financials) will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make such information, in light of the circumstances under which they were made, not misleading.

71

Notwithstanding the foregoing, Aspen makes no covenant, representation or warranty with respect to statements made in the Proxy Statement (or any amendment or supplement thereto), if any, based on information provided by the Company or its Subsidiaries or any of their Representatives for inclusion therein.

(d)    As soon as practicable following the date on which all comments to the Proxy Statement have been cleared, each of the Parties shall use commercially reasonable efforts to cause the Proxy Statement to be mailed to Aspen’s stockholders and, pursuant thereto, shall call an Aspen Stockholder Meeting in accordance with its Organizational Documents and the DGCL and, subject to the other provisions of this Agreement, solicit proxies from such holders to vote in favor of the issuance of shares of Aspen Common Stock to the stockholders of the Company in the Merger, the approval of the PIPE Investment and other matters presented to Aspen Stockholders for approval or adoption at the Aspen Stockholder Meeting, including, without limitation, the matters described in Section 6.3. If Aspen, Merger Sub or the Company become aware of any event or information that, pursuant to the Securities Act or the Exchange Act, should be disclosed in an amendment or supplement to the Proxy Statement, then such Party, as the case may be, shall promptly inform the other Parties thereof and shall cooperate with such other Parties in filing such amendment or supplement with the SEC and, if appropriate, in mailing such amendment or supplement to Aspen’s stockholders.

(e)    The Company shall reasonably cooperate with Aspen and provide, and cause its Representatives to provide, Aspen and its Representatives, with all true, correct and complete information regarding the Company or its Subsidiaries that is required by Law to be included in the Proxy Statement.

(f)    As promptly as reasonably practicable following the date of this Agreement the Company will furnish to Aspen audited financial statements for each of its fiscal years required to be included in the Proxy Statement (the “Company Audited Financial Statements”) and the Company will furnish to Aspen unaudited interim financial statements for each interim period completed prior to Closing that would be required to be included in the Proxy Statement or any periodic report due prior to the Closing if the Company were subject to the periodic reporting requirements under the Securities Act or the Exchange Act (the “Company Interim Financial Statements”). Each of the Company Audited Financial Statements and the Company Interim Financial Statements will be suitable for inclusion in the Proxy Statement and prepared in accordance with GAAP as applied on a consistent basis during the periods involved (except in each case as described in the notes thereto) and on that basis will present fairly, in all material respects, the financial position and the results of operations, changes in stockholders’ equity, and cash flows of the Company as of the dates of and for the periods referred to in the Company Audited Financial Statements or the Company Interim Financial Statements, as the case may be.

6.2    Company Stockholder Written Consent.

(a)    Promptly after the execution of this Agreement, the Company shall use its best efforts to take all lawful action to obtain the approval by written consent from Company stockholders sufficient for the Required Company Stockholder Vote in lieu of a meeting pursuant to Section 228 of the DGCL, for purposes of (i) adopting and approving this Agreement and the Contemplated Transactions, (ii) acknowledging that the approval given thereby is irrevocable and that such stockholder is aware of its rights to demand appraisal for its shares pursuant to Section 262 of the DGCL and

72

Chapter 13 of California Law, a copy of which will be attached thereto, and that such stockholder has received and read a copy of Section 262 of the DGCL and Chapter 13 of California Law and (iii) acknowledging that by its approval of the Merger it is not entitled to appraisal rights with respect to its shares in connection with the Merger and thereby waives any rights to receive payment of the fair value of its capital stock under the DGCL or California Law. Under no circumstances shall the Company assert that any other approval or consent is necessary by its stockholders to approve this Agreement and the Contemplated Transactions.

(b)    Reasonably promptly following receipt of the Required Company Stockholder Vote, the Company shall prepare and mail a notice (the “Stockholder Notice”) to every stockholder of the Company that did not execute the Company Stockholder Written Consent. The Stockholder Notice shall (i) be a statement to the effect that the Company Board determined that the Merger is advisable in accordance with Section 251(b) of the DGCL and in the best interests of the stockholders of the Company and approved and adopted this Agreement, the Merger and the other Contemplated Transactions, (ii) provide the stockholders of the Company to whom it is sent with notice of the actions taken in the Company Stockholder Written Consent, including the adoption and approval of this Agreement, the Merger and the other Contemplated Transactions in accordance with Section 228(e) of the DGCL and the certificate of incorporation and bylaws of the Company and (iii) include a description of the appraisal rights of the Company’s stockholders available under the DGCL and California Law, along with such other information as is required thereunder and pursuant to applicable Law. All materials (including any amendments thereto) submitted to the stockholders of the Company in accordance with this Section 6.2(b) shall be subject to Aspen’s advance review and reasonable approval which approval shall not be unreasonably withheld, delayed or conditioned.

(c)    The Company agrees that, subject to Section 6.2(d): (i) the Company Board shall recommend that the Company’s stockholders vote to adopt and approve this Agreement and the Contemplated Transactions and shall use commercially reasonable efforts to solicit such approval as set forth in Section 6.2(a) (the recommendation of the Company Board that the Company’s stockholders vote to adopt and approve this Agreement being referred to as the “Company Board Recommendation”) and (ii) the Company Board Recommendation shall not be withdrawn or modified (and the Company Board shall not publicly propose to withdraw or modify the Company Board Recommendation) in a manner adverse to Aspen, and no resolution by the Company Board or any committee thereof to withdraw or modify the Company Board Recommendation in a manner adverse to Aspen or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed.

(d)    The Company’s obligation to solicit the consent of its stockholders to sign the Company Stockholder Written Consent in accordance with Section 6.2(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or other Acquisition Proposal.

6.3    Aspen Stockholder Meeting.

(a)    Aspen shall take all action necessary under applicable Law to call, give notice of and hold a meeting of the holders of Aspen Common Stock to consider and vote to approve:

(i)    the Contemplated Transactions, including the issuance of shares of Aspen Common Stock to the stockholders of the Company pursuant to the terms of this Agreement;

73

(ii)    the issuance of shares of Aspen Common Stock and Aspen Pre-Funded Warrants to the PIPE Investors in connection with the PIPE Investment;

(iii)    the change of control of Aspen resulting from the Merger pursuant to the Nasdaq rules;

(iv)     the adoption and approval of the amendments to the Aspen A&R Charter and, to the extent required by applicable law or regulation, Aspen A&R Bylaws;

(vi)    in accordance with Section 14A of the Exchange Act and the applicable SEC rules issued thereunder, seeking advisory approval of a proposal to Aspen’s stockholders for a non-binding, advisory vote to approve certain compensation that may become payable to Aspen’s named executed officers in connection with the completion of the Merger, if applicable; and

(vii)    if deemed necessary by the Parties, an amendment to Aspen’s certificate of incorporation to effect the Nasdaq Reverse Split (the matters contemplated by the clauses 6.3(a)(i) – (vii) are referred to as the “Aspen Stockholder Matters,” and such meeting, the “Aspen Stockholder Meeting”).

The Aspen Stockholder Meeting shall be held as promptly as practicable after the Proxy Statement is “cleared” by the SEC. Aspen shall take reasonable measures to ensure that all proxies solicited in connection with the Aspen Stockholder Meeting are solicited in compliance with all applicable Law and Aspen’s Organizational Documents. Notwithstanding anything to the contrary contained herein, if on the date of the Aspen Stockholder Meeting, or a date preceding the date on which the Aspen Stockholder Meeting is scheduled, Aspen reasonably believes that (i) it will not receive proxies sufficient to obtain the Required Aspen Stockholder Vote, whether or not a quorum would be present or (ii) it will not have sufficient shares of Aspen Common Stock represented (whether in person or by proxy) to constitute a quorum necessary to conduct the business of the Aspen Stockholder Meeting, Aspen may postpone or adjourn, or make one or more successive postponements or adjournments of, the Aspen Stockholder Meeting as long as the date of the Aspen Stockholder Meeting is not postponed or adjourned more than an aggregate of 30 calendar days in connection with any postponements or adjournments, provided, however, that more than one such postponement or adjournment shall not be permitted without the Company’s prior written consent, not to be unreasonably withheld or delayed.

(b)    Aspen agrees that, subject to Section 6.3(c): (i) the Aspen Board shall recommend that the holders of Aspen Common Stock vote to approve the Aspen Stockholder Matters and shall use commercially reasonable efforts to solicit such approval within the timeframe set forth in Section 6.3(a) above, (ii) the Proxy Statement shall include a statement to the effect that the Aspen Board recommends that Aspen’s stockholders vote to approve the Aspen Stockholder Matters (the recommendation of the Aspen Board being referred to as the “Aspen Board Recommendation”) and (iii) the Aspen Board Recommendation shall not be withheld, amended, withdrawn or modified (and the Aspen Board shall not publicly propose to withhold, amend, withdraw or modify the Aspen Board Recommendation) in a manner adverse to

74

the Company, and no resolution by the Aspen Board or any committee thereof to withdraw or modify the Aspen Board Recommendation in a manner adverse to the Company or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed (the actions set forth in the foregoing clause (iii), collectively, a “Aspen Board Adverse Recommendation Change”).

(c)    Notwithstanding anything to the contrary contained in Section 6.3(b), and subject to compliance with Section 5.4 and Section 6.3, at any time prior to the approval of Aspen Stockholder Matters by the Required Aspen Stockholder Vote, (i) Aspen receives a written Acquisition Proposal and, after consultation with outside legal counsel, the Aspen Board shall have determined, in good faith, that such Acquisition Proposal is a Superior Offer or (ii) as a result of a material development or change in circumstances that was not known to, or reasonably foreseeable by, the Aspen board prior to the date hereof (other than any such event, development or change (A) to the extent related to any Acquisition Proposal, Acquisition Inquiry or the consequences thereof or (B) that would not be taken into account when determining whether an Aspen Material Adverse Effect or a Company Material Adverse Effect has occurred) that affects the business, assets or operations of Aspen that occurs or arises after the date of this Agreement (a “Aspen Intervening Event”), the Aspen Board may make a Aspen Board Adverse Recommendation Change if, but only if: (y) in the receipt of and on account of such Superior Offer, the Aspen Board determines in good faith, based on the advice of its outside legal counsel, that the failure to make a Aspen Board Adverse Recommendation Change would reasonably be likely to violate its fiduciary duties under applicable Law; provided that (1) the Company receives written notice from Aspen confirming that the Aspen Board has determined to change its recommendation during the Notice Period, which notice shall include a description in reasonable detail of the reasons for such Aspen Board Adverse Recommendation Change, and written copies of any relevant proposed transaction agreements with any party making a potential Superior Offer, (2) during any Notice Period, the Company shall be entitled to deliver to Aspen one or more counterproposals to such Acquisition Proposal and Aspen will, and cause its Representatives to, negotiate with the Company in good faith (to the extent the Company desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the applicable Acquisition Proposal ceases to constitute a Superior Offer and (3) in the event of any material amendment to any Superior Offer (including any revision in price or percentage of the combined company that Aspen’s stockholders would receive as a result of such potential Superior Offer), Aspen shall be required to provide the Company with notice of such material amendment and the Notice Period shall be extended, if applicable, to ensure that at least two (2) Business Days remain in the Notice Period following such notification during which the parties shall comply again with the requirements of this Section 6.3(c) and the Aspen Board shall not make a Aspen Board Adverse Recommendation Change prior to the end of such Notice Period as so extended (it being understood that there may be multiple extensions) or (z) in the case of a Aspen Intervening Event, Aspen promptly notifies the Company, in writing, within the Notice Period before making a Aspen Board Adverse Recommendation Change, which notice shall state expressly the material facts and circumstances related to the applicable Aspen Intervening Event and that the Aspen Board intends to make a Aspen Board Adverse Recommendation Change.

(d)    Aspen’s obligation to call, give notice of and hold the Aspen Stockholder Meeting in accordance with Section 6.3(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or Acquisition Proposal, or by any withdrawal or modification of the Aspen Board Recommendation.

(e)    Nothing contained in this Agreement shall prohibit Aspen or the Aspen Board from complying with Rules 14d-9 and 14e-2(a) promulgated under the Exchange

75

Act; provided however, that any disclosure made by Aspen or the Aspen Board pursuant to Rules 14d-9 and 14e-2(a) shall be limited to a statement that Aspen is unable to take a position with respect to the bidder’s tender offer unless the Aspen Board determines in good faith, after consultation with its outside legal counsel, that such statement would reasonably be likely to violate its fiduciary duties under applicable Law.

6.4    Efforts; Regulatory Approvals.

(a)    The Parties shall use reasonable best efforts to consummate the Contemplated Transactions. Without limiting the generality of the foregoing, each Party: (i) shall make all filings and other submissions (if any) and give all notices (if any) required to be made and given by such Party in connection with the Contemplated Transactions as set forth on Section 6.4(i) of the Aspen Disclosure Schedule or the Company Disclosure Schedule, respectively, (ii) shall use commercially reasonable efforts to obtain each Consent required to be obtained (pursuant to any applicable Law or Material Contract, or otherwise) by such Party in connection with the Contemplated Transactions or for such Material Contract to remain in full force and effect as set forth on Section 6.4(ii) of the Aspen Disclosure Schedule or the Company Disclosure Schedule, respectively, (iii) shall use commercially reasonable efforts to lift any injunction prohibiting, or any other legal bar to, the Contemplated Transactions and (iv) shall use commercially reasonable efforts to satisfy the conditions precedent to the consummation of this Agreement.

(b)    Notwithstanding the generality of the foregoing, each Party shall use commercially reasonable efforts to file or otherwise submit, as soon as practicable after the date of this Agreement, all applications, notices, reports and other documents reasonably required to be filed by such Party with or otherwise submitted by such Party to any Governmental Authority with respect to the Contemplated Transactions, and to submit promptly any additional information requested by any such Governmental Authority. To the extent required by applicable Law, without limiting the generality of the foregoing, the Parties shall, promptly and no later than ten (10) Business Days after the date of this Agreement, prepare and file, if any, (a) the notification and report forms required to be filed under the HSR Act and (b) any notification or other document required to be filed in connection with the Merger under any applicable foreign Law relating to antitrust or competition matters. The Company and Aspen shall respond as promptly as is practicable to respond in compliance with: (i) any inquiries or requests received from the Federal Trade Commission or the Department of Justice for additional information or documentation and (ii) any inquiries or requests received from any state attorney general, foreign antitrust or competition authority or other Governmental Authority in connection with antitrust or competition matters.

(c)    Without limiting the generality of the foregoing, the Parties shall, promptly and no later than ten (10) Business Days after the date of this Agreement, prepare and file, if any, (a) the notification and report forms required to be filed under the HSR Act and (b) any notification or other document required to be filed in connection with the Merger under any applicable foreign Law relating to antitrust or competition matters. The Company and Aspen shall respond as promptly as is practicable to respond in compliance with: (i) any inquiries or requests received from the Federal Trade Commission or the Department of Justice for additional information or documentation and (ii) any inquiries or requests received from any state attorney general, foreign antitrust or competition authority or other Governmental Authority in connection with antitrust or competition matters.

6.5    Company Options.

(a)    Subject to Section 6.5(c), at the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time under the Company Plan, whether or not vested, shall be converted into and become an option to purchase Aspen Common Stock, and Aspen shall assume the Company Plan and each such Company Option in accordance with the terms (as in effect as of the date of this Agreement) of the Company Plan and the terms of the stock option agreement by which such Company Option is evidenced (but with changes to such documents as Aspen and the Company mutually agree are appropriate to reflect the assumption of the Company Options by Aspen to purchase shares of Aspen Common Stock). All rights with respect to Company Common Stock under Company Options assumed by Aspen shall thereupon be converted into rights with respect to Aspen Common Stock. Accordingly, from and after the Effective Time: (i) each Company Option assumed by Aspen may be exercised solely for shares of Aspen Common Stock, (ii) the number of shares of Aspen Common Stock subject to each Company Option assumed by Aspen shall be determined by multiplying (A) the number of shares of Company Common Stock that were subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Aspen Common Stock, (iii) the per share exercise price for the Aspen Common Stock issuable upon exercise of each Company Option assumed by Aspen shall be determined by dividing (A) the per share exercise price of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent and (iv) any restriction on the exercise of any Company Option assumed by Aspen shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged; provided, however, that: (A) to the extent provided under the terms of a Company Option, such Company Option assumed by Aspen in accordance with this Section 6.5(a) shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction with respect to Aspen Common Stock subsequent to the Effective Time and (B) the Aspen Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to each Company Option assumed by Aspen. Notwithstanding anything to the contrary in this Section 6.5(a), the conversion of each Company Option (regardless of whether such option qualifies as an “incentive stock option” within the meaning of Section 422 of the Code) into an option to purchase shares of Aspen Common Stock shall be made in a manner consistent with Treasury Regulations Section 1.424-1, such that the conversion of a Company Option shall not constitute a “modification” of such Company Option for purposes of Section 409A or Section 424 of the Code.

(b)    Aspen shall file with the SEC, as soon as reasonably practicable after the Effective Time, a registration statement on Form S-8 (or any successor form), if available for use by Aspen, relating to the shares of Aspen Common Stock issuable with respect to Company Options assumed by Aspen in accordance with Section 6.5(a).

(c)    Prior to the Effective Time, the Company shall take all actions that may be necessary to effectuate the provisions of this Section 6.5 and to ensure that, from and after the Effective Time, holders of Company Options have no rights with respect thereto other than those specifically provided in this Section 6.5.

(a)    Prior to the Closing, the Aspen Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide that the vesting of each unexpired, unexercised and unvested Aspen Option, shall be accelerated in full effective as of immediately prior to the Effective Time and each unexpired, unexercised, and fully vested Aspen Option shall continue to remain outstanding in accordance with its terms after the Effective Time.

(b)    With respect to the Aspen ESPP, as soon as practicable (and in any event within ten days) following the date hereof, the Aspen Board will adopt resolutions and take other actions as may be reasonably necessary or required to provide that (i) each individual participating in an Offering (as defined in the Aspen ESPP) in progress on the date hereof will not be permitted to (A) increase his or her payroll contribution rate pursuant to the Aspen ESPP from the rate in effect as of the date hereof; or (B) make separate non-payroll contributions to the Aspen ESPP on or following the date hereof, except as may be required by applicable law, and (ii) no individuals will be permitted to newly enroll in the Aspen ESPP following the date hereof. Prior to the Closing Date, Aspen will take all action that may be necessary to, cause any outstanding Offering that is in progress on such date shall terminate and be the final Offering under the Aspen ESPP and the accumulated payroll deductions of each participant under the Aspen ESPP will be returned to the participant by Aspen pursuant to the terms of the Aspen ESPP, without issuance of any shares of Aspen Common Stock.

6.7    Employee Benefits.

(a)    Aspen and the Company shall cause Aspen to comply with the terms of any employment, severance, retention, change of control, or similar agreement specified on Section 4.17(c) of the Aspen Disclosure Schedule, subject to the provisions of such agreements.

(b)    Unless otherwise requested by the Company in writing at least ten (10) business days prior to the Closing Date, the Aspen Board shall take (or cause to be taken) all actions to adopt such resolutions as may be necessary or appropriate to terminate, effective no later than the day prior to the Closing Date, any Aspen Employee Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (a “Aspen 401(k) Plan”). If Aspen is required to terminate any Aspen 401(k) Plan, then Aspen shall provide to the Company prior to the Closing Date written evidence of the adoption by the Aspen Board of resolutions authorizing the termination of such Aspen 401(k) Plan (the form and substance of which shall be subject to the reasonable prior review and approval of the Company).

6.8    Indemnification of Officers and Directors.

(a)    From the Effective Time through the sixth anniversary of the date on which the Effective Time occurs, each of Aspen and the Surviving Corporation shall 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 Aspen or the Company, respectively (the “D&O Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements (collectively, “Costs”), incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the D&O Indemnified Party is or was a director or officer of Aspen or of the Company, whether asserted or claimed prior to, at or after the Effective Time, in each case, to the fullest extent permitted under the DGCL.

78

advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Aspen and the Surviving Corporation, jointly and severally, upon receipt by Aspen or the Surviving Corporation from the D&O Indemnified Party of a request therefor; provided that any such person to whom expenses are advanced provides an undertaking to Aspen, to the extent then required by the DGCL, to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

(d)    From and after the Effective Time, Aspen shall maintain directors’ and officers’ liability insurance policies, with an effective date as of the Closing Date, on commercially available terms and conditions and with coverage limits customary for U.S. public companies similarly situated to Aspen. In addition, Aspen shall purchase, prior to the Effective Time, a six-year prepaid “D&O tail policy” for the non-cancellable extension of the directors’ and officers’ liability coverage of Aspen’s existing directors’ and officers’ insurance policies for a claims reporting or discovery period of at least six years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under Aspen’s existing policies as of the date of this Agreement with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a director or officer of Aspen by reason of him or her serving in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the Contemplated Transactions or in connection with Aspen’s initial public offering of shares of Aspen Common Stock). During the term of the “tail” policy, Aspen shall not take any action following the Effective Time to cause such “tail” policy to be cancelled or any provision therein to be amended or waived in any manner that would adversely affect in any material respect the rights of their former and current officers and directors

10.2    Effect of Termination.

(a)    Except as set forth in this Section 10.3 and Section 6.10 all Transaction Costs and other expenses incurred in connection with this Agreement and the Contemplated Transactions shall be paid by the Party incurring such expenses, whether or not the Merger is consummated.

89

(b)    If (i) this Agreement is terminated by Aspen or the Company pursuant to Section 10.1(b) or 10.1(e) or by the Company pursuant to Section 10.1(f), (ii) at any time after the date of this Agreement and prior to the Aspen Stockholder Meeting an Acquisition Proposal with respect to Aspen shall have been publicly announced, disclosed or otherwise communicated to the Aspen Board (and shall not have been withdrawn) and (iii) in the event this Agreement is terminated pursuant to Section 10.1(e), within twelve (12) months after the date of such termination, Aspen enters into a definitive agreement with respect to a Subsequent Transaction or consummates a Subsequent Transaction whether or not in respect of the Acquisition Proposal referred to in clause (ii), then Aspen shall pay to the Company, within two (2) Business Days after termination (or, if applicable, upon such entry into a definitive agreement and/or consummation of a Subsequent Transaction), a nonrefundable fee in an amount equal to $2,000,000 (the “Company Termination Fee”).

(c)    If this Agreement is terminated by Aspen pursuant to Section 10.1(j), then Aspen shall pay to the Company, concurrent with such termination, the Company Termination Fee.

Subject to Section 10.2, following the payment of the fees and expenses set forth in this Section 10.3 by a Party, (i) such Party shall have no further liability to the other Party in connection with or arising out of this Agreement or the termination thereof, any breach of this Agreement by the other Party giving rise to such termination, or the failure of the Contemplated Transactions to be consummated, (ii) no other Party or their respective Affiliates shall be entitled to bring or maintain any other claim, action or proceeding against such Party or seek to obtain any recovery, judgment or damages of any kind against such Party (or any partner, member, stockholder, director, officer, employee, Subsidiary, Affiliate, agent or other representative of such Party) in connection with or arising out of this Agreement or the termination thereof, any breach

90

by such Party giving rise to such termination or the failure of the Contemplated Transactions to be consummated and (iii) all other Parties and their respective Affiliates shall be precluded from any other remedy against such Party and its Affiliates, at law or in equity or otherwise, in connection with or arising out of this Agreement or the termination thereof, any breach by such Party giving rise to such termination or the failure of the Contemplated Transactions to be consummated. Each of the Parties acknowledges that (x) the agreements contained in this Section 10.3 are an integral part of the Contemplated Transactions, (y) without these agreements, the Parties would not enter into this Agreement and (z) any amount payable pursuant to this Section 10.3 is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate the Parties in the circumstances in which such amount is payable.

(b)    No Party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Party and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

93

otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity, and each of the Parties waives any bond, surety or other security that might be required of any other Party with respect thereto. Each of the Parties further agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. Any Party seeking an injunction or injunctions to prevent breaches of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

11.11    No Third Party Beneficiaries . Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties and the D&O Indemnified Parties to the extent of their respective rights pursuant to Section 6.9) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

AERPIO PHARMACEUTICALS, INC.

SUPPORT AGREEMENT

THIS SUPPORT AGREEMENT (this “Agreement”), dated as of May 16, 2021, is made by and among Aerpio Pharmaceuticals, Inc., a Delaware corporation (“Aspen”), Aadi Bioscience, Inc., a Delaware corporation (the “Company”), and the undersigned holders (each a “Stockholder”) of shares of capital stock (the “Shares”) of Aspen.

WHEREAS, Aspen, Aspen Merger Subsidiary, Inc., a Delaware corporation and a wholly owned subsidiary of Aspen (“Merger Sub”), and the Company, have entered into an Agreement and Plan of Merger, dated of even date herewith (the “Merger Agreement”), providing for the merger of Merger Sub with and into the Company (the “Merger”);

WHEREAS, each Stockholder beneficially owns and has sole or shared voting power with respect to the number of Shares, and holds Aspen Options and/or Aspen Warrants to acquire the number of Shares indicated opposite such Stockholder’s name on Schedule 1 attached hereto;

WHEREAS, as an inducement and a condition to the willingness of the Company to enter into the Merger Agreement, each Stockholder has agreed to enter into and perform this Agreement; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Merger Agreement.

NOW, THEREFORE, in consideration of, and as a condition to, the Company’s entering into the Merger Agreement, each Stockholder, Aspen and the Company agree as follows:

1.    Agreement to Vote Shares. Each Stockholder agrees that, prior to the Expiration Date (as defined in Section 2 below), at any meeting of the stockholders of Aspen or any adjournment or postponement thereof, or in connection with any written consent of the stockholders of Aspen, with respect to the Merger, the Merger Agreement or any Acquisition Proposal, such Stockholder shall:

(a)    appear at such meeting or otherwise cause the Shares and any New Shares (as defined in Section 3 below) to be counted as present thereat for purposes of calculating a quorum;

(b)    from and after the date hereof until the Expiration Date, vote (or cause to be voted), or deliver a written consent (or cause a written consent to be delivered) covering all of the Shares and any New Shares that Stockholder shall be entitled to so vote: (i) in favor of (A) approval of the issuance of the shares of Aspen Common Stock by virtue of the Merger, (B) approval of the issuance of the shares of Aspen Common Stock in connection with the PIPE Investment, and (C) any matter that could reasonably be expected to facilitate the Merger, the PIPE Investment and the Contemplated Transactions; (ii) against any Acquisition Proposal, or any agreement, transaction or other matter that is intended to, or would reasonably be expected to, impede, interfere with, delay, postpone,

discourage or materially and adversely affect the consummation of the Merger, the PIPE Investment and all of the other Contemplated Transactions; and (iv) to approve any proposal to adjourn or postpone the meeting to a later date, if there are not sufficient votes for the adoption of the Merger Agreement on the date on which such meeting is held. Stockholder shall not take or commit or agree to take any action inconsistent with the foregoing.

2.    Expiration Date. As used in this Agreement, the term “Expiration Date” shall mean the earlier to occur of (a) the Effective Time, (b) such date and time as the Merger Agreement shall be terminated pursuant to Section 10 thereof or otherwise, or (c) the mutual written agreement of the parties to terminate this Agreement.

3.    Additional Acquisitions. Each Stockholder agrees that any shares of capital stock or other equity securities of Aspen that such Stockholder acquires or with respect to which such Stockholder otherwise acquires sole or shared voting power (including any proxy) after the execution of this Agreement and prior to the Expiration Date, whether by the exercise of any Aspen Options, Aspen Warrants or otherwise, including, without limitation, by gift, succession, in the event of a stock split or as a dividend or distribution of any Shares (“New Shares”), shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Shares.

4.    Agreement to Retain Shares. From and after the date hereof until the Expiration Date, each Stockholder shall not, directly or indirectly, (a) sell, assign, transfer, tender, or otherwise dispose of (including, without limitation, by the creation of any Liens (as defined in Section 5(c) below)) any Shares or any New Shares, (b) deposit any Shares or New Shares into a voting trust or enter into a voting agreement or similar arrangement with respect to such Shares or New Shares or grant any proxy or power of attorney with respect thereto (other than this Agreement), (c) enter into any Contract, option, commitment or other arrangement or understanding with respect to the direct or indirect sale, transfer, assignment or other disposition of (including, without limitation, by the creation of any Liens) any Shares or New Shares, or (d) take any action that would make any representation or warranty of such Stockholder contained herein untrue or incorrect or have the effect of preventing or disabling such Stockholder from performing such Stockholder’s obligations under this Agreement. Any action taken in violation of the foregoing sentence shall be null and void ab initio. Notwithstanding the foregoing, each Stockholder may make (1) transfers by will or by operation of Law or other transfers for estate-planning purposes, in which case this Agreement shall bind the transferee, (2) with respect to such Stockholder’s Aspen Options which expire on or prior to the Expiration Date, transfers, sale, or other disposition of Shares to Aspen as payment for the (i) exercise price of such Stockholder’s Aspen Options and (ii) taxes applicable to the exercise of such Stockholder’s Aspen Options, (3) if Stockholder is a partnership or limited liability company, a transfer to one or more partners or members of Stockholder or to an Affiliated corporation, trust or other Entity under common control with Stockholder, or if Stockholder is a trust, a transfer to a beneficiary, provided that in each such case the applicable transferee has signed a voting agreement in substantially the form hereof, (4) make transfers that occur by operation of law pursuant to a qualified domestic relations order or in connection with a divorce settlement, and (5) transfers, sales or other dispositions as the Company may otherwise agree in writing in its sole discretion. If any voluntary or involuntary transfer of any Shares covered hereby shall occur (including a transfer or disposition permitted by Section 4(1) through Section 4(5), sale by a Stockholder’s trustee in bankruptcy, or a sale to a

2

purchaser at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Shares subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect, notwithstanding that such transferee is not a Stockholder and has not executed a counterpart hereof or joinder hereto.

5.    Representations and Warranties of Stockholder. Each Stockholder hereby, severally but not jointly, represents and warrants to Aspen and the Company as follows:

If such Stockholder is an individual, such Stockholder has the legal capacity to execute and deliver this Agreement, to perform such Stockholder’s obligations hereunder and to consummate the transactions contemplated hereby;

(b)    this Agreement has been duly executed and delivered by or on behalf of such Stockholder and, to such Stockholder’s knowledge and assuming this Agreement constitutes a valid and binding agreement of the Company and Aspen, constitutes a valid and binding agreement with respect to such Stockholder, enforceable against such Stockholder in accordance with its terms, except as enforcement may be limited by general principles of equity whether applied in a court of Law or a court of equity and by bankruptcy, insolvency and similar Laws affecting creditors’ rights and remedies generally;

(c)    such Stockholder beneficially owns the number of Shares indicated opposite such Stockholder’s name on Schedule 1, and will own any New Shares, free and clear of any liens, claims, charges or other encumbrances or restrictions of any kind whatsoever (“Liens”), and has sole or shared, and otherwise unrestricted, voting power with respect to such Shares or New Shares and none of the Shares or New Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares or the New Shares, except as contemplated by this Agreement;

(d)    to the knowledge of such Stockholder, the execution and delivery of this Agreement by such Stockholder does not, and the performance by such Stockholder of his, her or its obligations hereunder and the compliance by such Stockholder with any provisions hereof will not, violate or conflict with, result in a material breach of or constitute a default (or an event that with notice or lapse of time or both would become a material default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of any Liens on any Shares or New

3

Shares pursuant to, any agreement, instrument, note, bond, mortgage, Contract, lease, license, permit or other obligation or any order, arbitration award, judgment or decree to which such Stockholder is a party or by which such Stockholder is bound, or any Law, statute, rule or regulation to which such Stockholder is subject or, in the event that such Stockholder is a corporation, partnership, trust or other Entity, any bylaw or other Organizational Document of such Stockholder; except for any of the foregoing as would not reasonably be expected to prevent or delay the performance by such Stockholder of his, her or its obligations under this Agreement in any material respect;

(e)    the execution and delivery of this Agreement by such Stockholder does not, and the performance of this Agreement by such Stockholder does not and will not, require any consent, approval, authorization or permit of, or filing with or notification to, any Governmental Authority or regulatory authority by such Stockholder except for applicable requirements, if any, of the Exchange Act, and except where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not prevent or delay the performance by such Stockholder of his, her or its obligations under this Agreement in any material respect;

6.    Irrevocable Proxy. Subject to the penultimate sentence of this Section 6, by execution of this Agreement, each Stockholder does hereby appoint the Company and any of its designees with full power of substitution and resubstitution, as such Stockholder’s true and lawful attorney and irrevocable proxy, to the fullest extent of such Stockholder’s rights with respect to the Shares, to vote and exercise all voting and related rights, including the right to sign such Stockholder’s name (solely in its capacity as a stockholder) to any Stockholder consent, if Stockholder is unable to perform or otherwise does not perform his, her or its obligations under this Agreement, with respect to such Shares solely with respect to the matters set forth in Section 1 hereof. Each Stockholder intends this proxy to be irrevocable and coupled with an interest hereunder until the Expiration Date, hereby revokes any proxy previously granted by such Stockholder with respect to the Shares and represents that none of such previously-granted proxies are irrevocable. The Stockholder hereby affirms that the proxy set forth in this Section 6 is given in connection with, and granted in consideration of, and as an inducement to the Company, Aspen and Merger Sub to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Stockholder under Section 1. The irrevocable proxy and power of attorney granted herein shall survive the death or incapacity of such Stockholder and the obligations of such Stockholder shall be binding on such Stockholder’s heirs, personal representatives, successors, transferees and assigns. Each Stockholder hereby agrees not to grant any subsequent powers of attorney or proxies with respect to any Shares with respect to the matters set forth in Section 1 until after the Expiration Date. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the Expiration Date.

7.    No Solicitation. From and after the date hereof until the Expiration Date, each Stockholder shall not (a) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry regarding Aspen or take any action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry regarding Aspen, (b) furnish any non-public information regarding Aspen to any Person in connection with or in response to an Acquisition Proposal or Acquisition Inquiry regarding Aspen, (c) engage in discussion or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry regarding Aspen, (d) approve, endorse or recommend any Acquisition Proposal (subject to Section 6.3 of the Merger Agreement), (e) execute or enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition Transaction regarding Aspen (subject to Section 5.4 of the Merger Agreement), (f) take any action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry regarding Aspen, (g) initiate a stockholders’ vote or action by consent of the Aspen’s stockholders with respect to an Acquisition Proposal regarding Aspen, (h) except by reason of this Agreement, become a member of a “group” (as such term is defined in Section 13(d) of the Exchange Act) with respect to any voting securities of Aspen that takes any action in support of an Acquisition Proposal regarding Aspen or (i) propose or agree to do any of the foregoing. In the event that such Stockholder is a corporation, partnership, trust or other Entity, it shall not permit any of its Subsidiaries or Affiliates to, nor shall it authorize any officer, director or representative of such Stockholder, or any of its Subsidiaries or Affiliates to, undertake any of the actions contemplated by this Section 7.

8.    No Legal Actions. Each Stockholder will not in its capacity as a stockholder of Aspen bring, commence, institute, maintain, prosecute or voluntarily aid any Legal Proceeding which (i) challenges the validity or seeks to enjoin the operation of any provision of this Agreement or (ii) alleges that the execution and delivery of this Agreement by such Stockholder, either alone or together with the other voting agreements and proxies to be delivered in connection with the execution of the Merger Agreement, or the approval of the Merger Agreement by the Aspen Board, constitutes a breach of any fiduciary duty of the Aspen Board or any member thereof.

9.    Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with, and not exclusive of, any other remedy conferred hereby, or by Law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof without the need of posting bond in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity.

10.    Directors and Officers. This Agreement shall apply to each Stockholder solely in such Stockholder’s capacity as a stockholder of Aspen and/or holder of Aspen Options and/or Aspen Warrants and not in such Stockholder’s capacity as a director, officer or employee of Aspen

5

or any of its Subsidiaries or in such Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall (or require Stockholder to attempt to) limit or restrict a director and/or officer of Aspen in the exercise of his or her fiduciary duties consistent with the terms of the Merger Agreement as a director and/or officer of Aspen or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust or prevent or be construed to create any obligation on the part of any director and/or officer of Aspen or any trustee or fiduciary of any employee benefit plan or trust from taking any action in his or her capacity as such director, officer, trustee and/or fiduciary.

11.    No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in the Company any direct or indirect ownership or incidence of ownership of or with respect to any Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to such Stockholder, and the Company does not have authority to manage, direct, superintend, restrict, regulate, govern, or administer any of the policies or operations of Aspen or exercise any power or authority to direct such Stockholder in the voting of any of the Shares, except as otherwise provided herein.

12.    Termination. This Agreement shall terminate and shall have no further force or effect as of the Expiration Date. Notwithstanding the foregoing, upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, nothing set forth in this Section 12 or elsewhere in this Agreement shall relieve any party from liability for any fraud or for any willful and material breach of this Agreement prior to termination hereof.

13.    Further Assurances. Each Stockholder shall, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further consents, documents and other instruments as the Company or Aspen may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement and the Contemplated Transactions.

14.    Disclosure. Each Stockholder hereby agrees that Aspen and the Company may publish and disclose in the Proxy Statement, any prospectus filed with any regulatory authority in connection with the Contemplated Transactions and any related documents filed with such regulatory authority and as otherwise required by Law, such Stockholder’s identity and ownership of Shares and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement and may further file this Agreement as an exhibit to the Proxy Statement or prospectus or in any other filing made by Aspen or the Company as required by Law or the terms of the Merger Agreement, including with the SEC or other regulatory authority, relating to the Contemplated Transactions, all subject to prior review and an opportunity to comment by Stockholder’s counsel. Prior to the Closing, each Stockholder shall not, and shall use its reasonable best efforts to cause its representatives not to, directly or indirectly, make any press release, public announcement or other public communication that criticizes or disparages this Agreement or the Merger Agreement or any of the Contemplated Transactions, without the prior written consent of Aspen and the Company, provided that the foregoing shall not limit or affect any actions taken by such Stockholder (or any affiliated officer or director of such Stockholder) that would be permitted to be taken by such Stockholder, Aspen or the Company pursuant to the Merger Agreement; provided, further, that the foregoing shall not effect any actions of Stockholder the prohibition of which would be prohibited under applicable Law.

15.    Notice. All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally or sent by overnight courier (providing proof of delivery), by facsimile transmission (providing confirmation of transmission) or by electronic transmission (providing confirmation of transmission) to the Company or Aspen, as the case may be, in accordance with Section 11.7 of the Merger Agreement and to each Stockholder at his, her or its address or email address (providing confirmation of transmission) set forth on Schedule 1 attached hereto (or at such other address for a party as shall be specified by like notice).

16.    Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. 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 or provision.

17.    Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and assigns; provided, however, that neither this Agreement nor any of a party’s rights or obligations hereunder may be assigned or delegated by such party without the prior written consent of the other parties hereto, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by such party without the other party’s prior written consent shall be void and of no effect. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

18.    No Waivers. No waivers of any breach of this Agreement extended by the Company or Aspen to such Stockholder shall be construed as a waiver of any rights or remedies of the Company or Aspen, as applicable, with respect to any other stockholder of Aspen who has executed an agreement substantially in the form of this Agreement with respect to Shares held or subsequently held by such stockholder or with respect to any subsequent breach of Stockholder or any other such stockholder of Aspen. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

19.    Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the Laws of the state of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of Laws. In any action or Legal Proceeding

7

between any of the parties arising out of or relating to this Agreement, each of the parties: (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the state of Delaware or to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, (ii) agrees that all claims in respect of such action or Legal Proceeding shall be heard and determined exclusively in accordance with clause (i) of this Section 19, (iii) waives any objection to laying venue in any such action or Legal Proceeding in such courts, (iv) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party, and (v) agrees that service of process upon such party in any such action or Legal Proceeding shall be effective if notice is given in accordance with Section 15 of this Agreement.

22.    Entire Agreement; Counterparts; Exchanges by Facsimile. This Agreement and the other agreements referred to in this Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all parties by facsimile or electronic transmission via “.pdf” shall be sufficient to bind the parties to the terms and conditions of this Agreement.

23.    Amendment. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed on behalf of each party hereto; provided, however, that the rights or obligations of any Stockholder may be waived, amended or otherwise modified in a writing signed by Aspen, the Company and such Stockholder.

2. Contingent Value Rights.

2.1 CVRs. The CVRs represent the rights of Holders to receive contingent cash payments pursuant to the Merger Agreement and this Agreement. The initial Holders will be the holders of the Common Stock as of immediately prior to the Effective Time. One CVR will be issued with respect to each share of Common Stock that is outstanding as of immediately prior to the Effective Time.

2.2 Nontransferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer. Any purported transfer of a CVR other than in a Permitted Transfer shall be null and void ab initio.

2.3 No Certificate; Registration; Registration of Transfer; Change of Address; CVR Distribution.

(a) The CVRs will be issued in book-entry form only and will not be evidenced by a certificate or other instrument. The CVRs will not be listed on any quotation system or traded on any securities exchange.

(b) The Rights Agent shall create and maintain a register (the “CVR Register”) for the registration of CVRs and Permitted Transfers. The CVR Register will be created, and CVRs will be distributed, pursuant to written instructions to the Rights Agent from the Company. The CVR Register will initially show one position for Cede & Co. representing all the shares of Common Stock held by DTC on behalf of the street holders of the shares of Common Stock held by such holders as of immediately prior to the Effective Time. The Rights Agent will have no responsibility whatsoever directly to the street name holders with respect to transfers of CVRs. With respect to any payments to be made under Section 2.4(d) below, the Rights Agent will accomplish the payment to any former street name holders of shares of Common Stock by sending one lump-sum payment to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument or instruments of transfer any other requested documentation in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, including a guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative or the Holder’s survivor, and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice, the Rights Agent shall, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions of this

6

Agreement and applicable law (including the provisions of Section 2.2), register the transfer of the CVRs in the CVR Register. The Company and Rights Agent may require evidence of payment of a sum sufficient to cover any stamp, documentary, registration, or other Tax or governmental charge that is imposed in connection with any such registration of transfer (or evidence that such Taxes and charges are not applicable). The Rights Agent shall have no duty or obligation to take any action under any section of this Agreement that requires the payment by a Holder of a CVR of applicable taxes or charges unless and until the Rights Agent is satisfied that all such taxes or charges have been paid. All duly transferred CVRs registered in the CVR Register will be the valid obligations of the Company and will entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR will be valid until registered in the CVR Register, and any transfer not duly registered in the CVR Register will be void and invalid. All costs and expenses related to any transfer or assignment of the CVRs (including the cost of any transfer tax) will be the responsibility of the transferor.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent shall, subject to its reasonable determination that the transfer instrument is in proper form, promptly record the change of address in the CVR Register. The Holder Representative may make a written request to the Rights Agent for a list containing the names, addresses and number of CVRs of the Holders that are registered in the CVR Register. Upon receipt of such written request from the Holder Representative, the Rights Agent shall promptly deliver a copy of such list to the Holder Representative.

(e) The Company will provide written instructions to the Rights Agent for the distribution of CVRs to holders of Common Stock as of immediately prior to the Effective Time (the “Record Time”). Subject to the terms and conditions of this Agreement and the Company’s prompt confirmation of the Effective Time, the Rights Agent shall effect the distribution of the CVRs, less any tax withholding required by applicable law, to each holder of Common Stock as of the Record Time by the mailing of a statement of holding reflecting such CVRs.

2.4 CVR Payment and Related Procedures.

(a) No later than 45 days after the end of each CVR Payment Period during the CVR Term, commencing with the first CVR Payment Period in which the Company or its subsidiaries receives Gross Consideration, the Company shall deliver to the Holder Representative a draft CVR Payment Statement for such CVR Payment Period for review by the Holder Representative. Following the time the amount of Gross Consideration is agreed or finally determined by the Parties pursuant to Section 2.4(d) of this Agreement and in any event within 10 Business Days, the Company and the Holder Representative shall jointly deliver to the Rights Agent a CVR Payment Statement for such CVR Payment Period. Concurrent with the delivery of each CVR Payment Statement, on the terms and conditions of this Agreement, the Company shall pay the Rights Agent in U.S. dollars an amount equal to 90% of Net Proceeds (if any) received with respect to the applicable CVR Payment Period. Such amount of Net Proceeds will be transferred by wire transfer of immediately available funds to an account designated in

7

writing by the Rights Agent not less than 20 Business Days prior to the date of the applicable payment. The Company shall be entitled to retain for its own benefit the remaining 10% of any such Net Proceeds (if any) received with respect to the applicable CVR Payment Period. For clarity, to the extent that any non-cash consideration in Gross Consideration is monetized after the end of the CVR Term, the Company will include a description of such non-cash consideration in the CVR Payment Statement for the CVR Payment Period in which it is received, and will make the applicable payment to the Rights Agent upon monetization of such non-cash consideration.

(b) All payments by the Company to the Rights Agent under this Agreement shall be made in U.S. dollars. The rate of exchange to be used in computing the amount of currency equivalent in U.S. dollars shall be made at the average of the closing exchange rates reported in The Wall Street Journal (U.S., Eastern Edition) for the ten Business Days preceding the date of the CVR Payment Statement.

(c) The Rights Agent will promptly, and in any event within ten Business Days after receipt of a CVR Payment Statement under Section 2.4(a), send each Holder at its address set forth on the CVR Register a copy of such statement (which statement may be modified or redacted, at the reasonable request of the Company, so as to provide only the total amount of Gross Consideration, the total amount of Permitted Deductions and the ultimate Net Proceeds payable thereunder in respect of each CVR). If the Rights Agent also receives any payment under Section 2.4(a) (each, a “CVR Payment”), then within ten Business Days after the receipt of each CVR Payment, the Rights Agent will also pay to each Holder, by check mailed, first-class postage prepaid, to the address of each Holder as reflected in the CVR Register as of the close of business on the date of the receipt of the CVR Payment Statement, such Holder’s Payment Amount.

(d) Upon the Holder Representative’s reasonable request after receipt of any statement under Section 2.4(a), the Company shall promptly provide the Holder Representative with reasonable documentation to support its calculation of Net Proceeds (including any allocation applied when calculating the Gross Consideration component thereof and including its determination of the applicable fair market values), and shall make its financial personnel reasonably available to the Holder Representative to discuss and answer the Holder Representative’s questions regarding such calculations. If the Holder Representative does not agree with the Company’s calculation, and the Holder Representative and the Company fail to agree on an alternative calculation within ten Business Days after the Holder Representative requests documentation supporting the Company’s calculation, then the Company and the Holder Representative shall engage a mutually agreeable independent third party valuation expert (a “Valuation Expert”) to determine the applicable calculation. The determination of the Valuation Expert will be final and binding on the Company, the Rights Agent, the Holder Representative, the Acting Holders and each Holder, unless the Company and Holder Representative agree otherwise in writing. The Valuation Expert shall be an investment banker or other Person experienced in the valuation of pharmaceutical businesses and products, who shall not have had any material business relationship with the Company or the Holder Representative in the 36 months prior to appointment, unless the Company and the Holder Representative agree in writing to waive this requirement. If the Holder Representative and the Company fail to agree on a Valuation Expert within 30 days after determining to seek a

8

Valuation Expert, the Holder Representative and the Company shall each designate a valuation expert, and the two such experts shall select a Valuation Expert. The Valuation Expert selected shall be entitled to apply discounted cash flow models and such other valuation models as she or he determines are appropriate under the circumstances, together with any other valuation models as may be agreed by the Holder Representative and the Company. Within ten Business Days after the selection of the Valuation Expert, each of the Company and the Holder Representative will deliver to the Valuation Expert a detailed written proposal setting forth its proposed calculation of the Net Proceeds and the Company will deliver to the Valuation Expert a copy of the applicable Third Party agreements. The Company and the Holder Representative will use reasonable efforts to cause the Valuation Expert to make a determination within 30 days after receipt of the proposals. Following its determination, the Valuation Expert shall deliver to the Company and the Holder Representative a report of her or his determination, and within 30 days after receipt of such report, the Company shall make the applicable payment to the Rights Agent. The fees charged by the Valuation Expert shall be borne 50% by the Holders (through deduction from the next one or more CVR Payments, including the CVR Payment evaluated by the Valuation Expert) and 50% by the Company.

(e) The Company shall be entitled to deduct and withhold, or cause the Rights Agent to deduct and withhold, any tax or similar governmental charge or levy, that is required to be deducted or withheld under applicable law from any amounts payable pursuant to this Agreement (“Withholding Taxes”). To the extent the amounts are so withheld by the Company or the Rights Agent, as the case may be, and paid over to the appropriate Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of whom such deduction and withholding was made. The Rights Agent shall request from each Holder an IRS Form W-9 or applicable IRS Form W-8 at such time or times as is necessary to permit any payment under this Agreement to be made without U.S. federal backup withholding. In the event the Company becomes aware that a payment under this Agreement is subject to Withholding Taxes (other than U.S. federal backup withholding), the Company shall use commercially reasonable efforts to provide written notice to the Rights Agent.

(f) Any portion of any CVR Payment that remains undistributed to the Holders six months after the CVR Payment is received by the Rights Agent from the Company, provided that the Rights Agent has fully complied with Section 2.4(c), will be delivered by the Rights Agent to the Company, upon demand, and any Holder will thereafter look only to the Company for payment of its share of such returned CVR Payment, without interest, but such Holder will have no greater rights against the Company than those accorded to general unsecured creditors of the Company under applicable law.

(g) If any CVR Payment (or portion thereof) remains unclaimed by a Holder two years after the applicable CVR Payment Period end (or immediately prior to such earlier date on which such CVR Payment would otherwise escheat to or become the property of any Governmental Authority), such CVR Payment (or portion thereof) will, to the extent permitted by applicable Law, become the property of the Company and will be transferred to the Company or a person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent), free and clear of all claims or interest of any Person previously entitled thereto, and no consideration or compensation shall be payable therefor. Neither the

9

Company nor the Rights Agent will be liable to any Person in respect of a CVR Payment delivered to a public official pursuant to any applicable abandoned property, escheat or similar legal requirement under applicable Law. In addition to and not in limitation of any other indemnity obligation herein, the Company agrees to indemnify and hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to the Company, a public office or a person nominated in writing by the Company.

(h) Notwithstanding the foregoing, the Company will not be obligated to make any CVR Payments unless the aggregate amount of the CVR Payments exceeds $1,000,000 in any given CVR Payment Period. If the amount of the CVR Payment is less than $1,000,000, such amount will be rolled over to the next CVR Payment Period until the amount of the CVR Payment exceeds $1,000,000. It is hereby agreed that if the amount of the CVR Payment does not exceed $1,000,000 in any given CVR Payment Period, the Company shall pay the total amount of the then unpaid CVR Payment immediately prior to the termination or expiry of this Agreement.

2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in the Company.

(a) The CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable in respect of CVRs to any Holder.

(b) The CVRs will not represent any equity or ownership interest in the Company or in any constituent company to the Merger. The rights of the Holders and the obligations of the Company are contract rights limited to those expressly set forth in this Agreement, and such Holders’ sole right to receive property hereunder is the right to receive cash from the Company, if any, through the Rights Agent in accordance with the terms hereof. It is hereby acknowledged and agreed that a CVR shall not constitute a security of the Company.

(c) Nothing contained in this Agreement shall be construed as conferring upon any Holder, by virtue of the CVRs, any rights or obligations of any kind or nature whatsoever as a stockholder or member of the Company or any of its subsidiaries either at law or in equity. The rights of any Holder and the obligations of the Company and its Affiliates and their respective officers, directors and controlling Persons are contract rights limited to those expressly set forth in this Agreement.

(d) It is hereby acknowledged and agreed that the CVRs and the possibility of any payment hereunder with respect thereto are highly speculative and subject to numerous factors outside of the Company’s control, and there is no assurance that Holders will receive any payments under this Agreement or in connection with the CVRs. Each Holder acknowledges that it is highly possible that there will not be any Gross Consideration that may be the subject of a CVR Payment. It is further acknowledged and agreed that neither the Company nor its Affiliates owe, by virtue of their obligations under this Agreement, a fiduciary duty or any implied duties to the Holders and the parties hereto intend solely the express provisions of this Agreement to govern their contractual relationship with respect to the CVRs. It is acknowledged and agreed that this Section 2.5(d) is an essential and material term of this Agreement.

10

2.6 Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights represented by CVRs by transferring such CVR to the Company or a Person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent) without consideration in compensation therefor, and such rights will be cancelled, with the Rights Agent being promptly notified in writing by the Company of such transfer and cancellation. Nothing in this Agreement is intended to prohibit the Company or its subsidiaries from offering to acquire or acquiring CVRs, in private transactions or otherwise, for consideration in its sole discretion.

2.7 Intended Tax Treatment. For U.S. federal income tax (and applicable state and local income tax purposes), the parties agree that (i) the distribution of the CVRs pursuant to Section 2.1 of this Agreement is intended to be treated as a distribution of property (and not debt or equity of the Company) by the Company to its stockholders governed by Section 301 of the Code and (ii) any CVR Payment (if any) is intended to be treated as a contractual payment pursuant to the rights afforded by this Agreement to the Holder and not as a distribution by the Company in respect of Company stock (collectively, the “Intended Tax Treatment”). The parties agree to file all tax returns and other tax reports in a manner consistent with the Intended Tax Treatment, unless a nationally recognized tax advisor approved by both the Company and the Rights Agent determines in written advice provided to the Company and Rights Agent that it is “more-likely-than-not” that such reporting is incorrect under U.S. federal income tax law.

3. The Rights Agent.

3.1 Appointment of Rights Agents; Certain Duties and Responsibilities. The Company hereby appoints the Rights Agent to act as agent for the Company in accordance with the express terms and conditions of this Agreement, and the Rights Agent hereby accepts such appointment. The Rights Agent will not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent of its fraud, willful misconduct, bad faith or gross negligence (in each case as determined by a final, non- appealable decision of a court of competent jurisdiction). Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damages of any kind whatsoever (including, without limitation, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damages, and regardless of the form of action.

(a) The Rights Agent will not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent such liability arises as a result of the fraud, willful misconduct, bad faith or gross negligence of the Rights Agent (in each case as determined by a final non-appealable judgment of court of competent jurisdiction). Notwithstanding anything in this Agreement to the contrary, any liability of the Rights Agent under this Agreement will be limited to the amount of annual fees paid by the Company to the Rights Agent (but not including reimbursable expenses and other charges) during the 18 months immediately preceding the event for which recovery from the Rights Agent is being sought. Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damages of any kind whatsoever (including, without limitation, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damages, and regardless of the form of action.

11

3.2 Certain Rights of Rights Agent

(a) The Rights Agent may rely and will be protected by the Company in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it in the absence of bad faith to be genuine and to have been signed or presented by or on behalf of the Company.

(b) Whenever the Rights Agent deems it desirable that a matter be proved or established prior to taking or omitting any action hereunder, the Rights Agent may rely upon an Officer’s Certificate, which certificate shall be full authorization and protection to the Rights Agent, and the Rights Agent shall, in the absence of fraud, bad faith, gross negligence or willful misconduct on its part (in each case as determined by a final, non-appealable decision of a court of competent jurisdiction), incur no liability and be held harmless by the Company for or in respect of any action taken or omitted to be taken by it under the provisions of this Agreement in reliance upon such Officer’s Certificate.

(c) The Rights Agent may engage and consult with counsel of its selection and the advice of such counsel or any opinion of counsel will be full and complete authorization and protection and shall be held harmless by the Company in respect of any action taken or omitted by it hereunder in the absence of fraud, bad faith, gross negligence or willful misconduct and in reliance thereon.

(j) The Rights Agent shall not be subject to, nor be required to comply with, or determine if any Person has complied with, the Merger Agreement or any other agreement between or among any of the Company, Aadi or Holders, even though reference thereto may be made in this Agreement, or to comply with any notice, instruction, direction, request or other communication, paper or document other than as expressly set forth in this Agreement.

(k) In the event the Rights Agent reasonably believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Rights Agent hereunder, the Rights Agent shall, as soon as practicable, provide notice to the Company, and the Rights Agent, may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to the Company or any Holder or any other Person for refraining from taking such action, unless the Rights Agent receives written instructions from the Company or such Holder or other Person which eliminate such ambiguity or uncertainty to the reasonable satisfaction of the Rights Agent;

3.4 Acceptance of Appointment by Successor.

Every successor Rights Agent appointed hereunder will, at or prior to such appointment, execute, acknowledge and deliver to the Company and to the resigning or removed Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and such successor Rights Agent, without any further act, deed or conveyance, will become vested with all the rights, powers, trusts and duties of the Rights Agent; provided that upon the request of the Company or the successor Rights Agent, such resigning or removed Rights Agent will execute and deliver an instrument transferring to such successor Rights Agent all the rights, powers and trusts of such resigning or removed Rights Agent.

5. The Holder Representative

5.1 Appointment of Holder Representative. The Holder Representative is hereby appointed, authorized and empowered to be the exclusive representative, agent and attorney-in-fact of each Holder, with full power of substitution, to make all decisions and determinations and to act (or not act) and execute, deliver and receive all agreements, documents, instruments and consents on behalf of and as agent for each Holder at any time in connection with, and that may be necessary or appropriate to accomplish the intent and implement the provisions of this Agreement and to facilitate the consummation of the transactions contemplated hereby, including without limitation for purposes of (i) negotiating and settling, on behalf of the Holders, any dispute that arises under this Agreement, (ii) confirming the satisfaction of the Company’s obligations under this Agreement and (iii) negotiating and settling matters with respect to the amounts to be paid to the Holders pursuant to this Agreement.

5.2 Authority. The appointment of the Holder Representative in accordance with this Agreement is coupled with an interest and may not be revoked in whole or in part (including, without limitation, upon the death or incapacity of any stockholder). Subject to the prior qualifications, such appointment shall be binding upon the heirs, executors, administrators, estates, personal representatives, officers, directors, security holders, successors and assigns of each Holder. All decisions of the Holder Representative shall be final and binding on all Holders. The Company and the Rights Agent shall be entitled to rely upon, without independent investigation, any act, notice, instruction or communication from the Holder Representative and any document executed by the Holder Representative on behalf of any Holder and shall be fully protected in connection with any action or inaction taken or omitted to be taken in reliance thereon, absent willful misconduct by the Company or the Rights Agent (as such willful misconduct is determined by a final, non-appealable judgment of a court of competent jurisdiction). The Holder Representative shall not be responsible, and shall be indemnified by the Holders and the Company, for any loss suffered by, or liability to the Holders, arising out of this Agreement, including as a result of legal action, arising out of any act done or omitted by the Holder Representative in connection with the acceptance or administration of the Holder Representative’s duties hereunder, unless such act or omission involves fraud, bad faith, gross negligence or willful misconduct.

16

5.3 Successor Holder Representative. The Holder Representative may be removed for any reason or no reason by written consent of the Acting Holders. In the event that the Holder Representative dies, becomes unable to perform his or her responsibilities hereunder or resigns or is removed from such position, the Acting Holders shall be authorized to and shall select another representative to fill such vacancy and such substituted representative shall be deemed to be the Holder Representative for all purposes of this Agreement. The newly-appointed Holder Representative shall notify the Company, the Rights Agent and any other appropriate Person in writing of his or her appointment, provide evidence that the Acting Holders approved such appointment and provide appropriate contact information for purposes of this Agreement. The Company and the Rights Agent shall be entitled to rely upon, without independent investigation, the identity and validity of such newly-appointed Holder Representative as set forth in such written notice. In the event that within 30 days after the Holder Representative dies, becomes unable to perform his or her responsibilities hereunder or resigns or is removed from such position, no successor Holder Representative has been so selected, the Company shall cause the Rights Agent to notify the Person holding the largest quantity of the outstanding CVRs (and who is not the Company or, to the Rights Agent’s actual knowledge, any Affiliate of the Company) that such Person is the successor Holder Representative, and such Person shall be the successor Holder Representative hereunder. If such Person notifies the Rights Agent in writing that such Person declines to serve, the Rights Agent shall forthwith notify the Person holding the next-largest quantity of the outstanding CVRs (and who is not the Company or, to the Rights Agent’s actual knowledge, any Affiliate of the Company) that such next-largest-quantity Person is the successor Holder Representative, and such next-largest-quantity Person shall be the successor Holder Representative hereunder. (And so on, to the extent as may be necessary.) The Holders are intended third party beneficiaries of this Section 8.3, provided that no enforcement may be brought hereunder unless and until such enforcement is approved by the Acting Holders. If a successor Holder Representative is not appointed pursuant to the preceding procedure within 60 days after the Holder Representative dies, becomes unable to perform his or her responsibilities hereunder or resigns or is removed from such position, the Company shall appoint a successor Holder Representative.

5.4 Termination of Duties and Obligations. The Holder Representative’s duties and obligations under this Agreement shall survive until no CVRs remain outstanding or until this Agreement expires or is terminated pursuant to Section 9.8, whichever is earlier.

(a) the Company may not assign this Agreement without the prior written consent of the Holder Representative, provided that (a) the Company may assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more direct or indirect wholly-owned subsidiaries of the

20

Company (each, an “Assignee”) provided that the Assignee agrees to assume and be bound by all of the terms of this Agreement; provided, however, that in connection with any assignment to an Assignee, the Company shall, and shall agree to, remain liable for the performance by such Assignee of all obligations of the Company hereunder, with such Assignee substituted for the Company under this Agreement, and (b) the Company may assign this Agreement in its entirety without the consent of any other party to its successor in interest in connection with the sale of all or substantially all of its assets or of its stock, or in connection with a merger, acquisition or similar transaction (such successor in interest, the “Acquiror”, and such transaction, the “Acquisition”). This Agreement will be binding upon, inure to the benefit of and be enforceable by the Company’s successors, acquirers and each Assignee. Each reference to “the Company” in this Agreement shall be deemed to include the Company’s successors, acquirers and all Assignees. Each of the Company’s successors, acquirers and assigns shall expressly assume by an instrument supplemental hereto, executed and delivered to the Rights Agent, the due and punctual payment of the CVR Payments and the due and punctual performance and observance of all of the covenants and obligations of this Agreement to be performed or observed by the Company.

(b) Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the stock transfer or other shareholder services business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the Parties hereto, provided that such Person would be eligible for appointment as a successor Rights Agent under the provisions of the Agreement. The purchase of all or substantially all of the Rights Agent’s assets employed in the performance of transfer agent activities shall be deemed a merger or consolidation for purposes of this Section 6.3(b).

7.4 Benefits of Agreement. Nothing in this Agreement, express or implied, will give to any Person (other than the Rights Agent, the Company, the Company’s successors and assignees, and the Holders) any benefit or any legal or equitable right, remedy or claim under this Agreement or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the Rights Agent, the Company, the Company’s successors and assignees, and the Holders. The rights of Holders are limited to those expressly provided in this Agreement and the Merger Agreement. Notwithstanding anything to the contrary contained herein, any Holder may agree to renounce, in whole or in part, such Holder’s rights under this Agreement by written notice to the Rights Agent and the Company, which notice, if given, shall be irrevocable. In such event, such Holder’s CVRs will not be included for determining the Payment Amounts to all other Holders.

7.5 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable. The Parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision; provided, however, that if such excluded provision shall affect the rights, immunities, liabilities, duties or obligations of the Rights Agent, the Rights Agent shall be entitled to resign immediately upon written notice to the Company.

21

7.6 Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by electronic scan delivered by electronic mail), each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties hereto and delivered to the other Party, it being understood that the Parties need not sign the same counterpart.

7.7 Termination.

(a) This Agreement will expire and be of no force or effect, and will terminate automatically upon the earlier of (a) the twenty (20) year anniversary of Closing, and (b) the time at which the License Agreement has expired or been terminated and no other amounts are reasonably expected to be owed under any other Covered Agreement (which the Company shall notify the Holder Representative of in writing).

(b) The Parties hereto will have no liability hereunder (other than with respect to monies due and owing by the Company to Rights Agent or any other rights of the Rights Agent which expressly survive the termination of this Agreement), and no additional payments will be required to be made upon the payment of the full amount of all CVR Payments to the Rights Agent and the payment of the full amount of all Payment Amounts to the Holders by the mailing by the Rights Agent of each applicable Payment Amount to each Holder at the address reflected in the CVR Register.

(c) The Company shall be permitted, prior to a change of control event, to terminate this Agreement so long as immediately prior to such termination, the Company agrees to pay out Net Proceeds under this Agreement for the remaining CVR Term, at the then existing fair market value of the amounts that remain payable or may be payable under this Agreement. The fair market value shall be mutually determined by the Company and the Holder Representative; provided that, if the Company and the Holder Representative are unable to agree, either Party may, upon request, cause the Company to engage a Valuation Expert to determine such value, using the same methods as described in Section 2.4(d) of this Agreement. It is hereby agreed and understood by the Parties that, so long as the Company pays no less than the amount determined by the Valuation Expert pursuant to Section 2.4(d) of this Agreement or as agreed with the Holder Representative, the Company will be considered to have fully satisfied all of its obligations under the Agreement, and the Company will be entitled to terminate this Agreement following the distribution of such amounts.

(d) Upon termination or expiry of this Agreement pursuant to this Section 7.7, all CVRs issued hereunder shall be automatically cancelled and forfeited by the Holders without any consideration or payment therefor.

22

7.8 Funds.

(LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). The Rights Agent shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by the Rights Agent in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other Third Party. The Rights Agent may from time to time receive interest, dividends or other earnings in connection with such deposits. The Rights Agent shall not be obligated to pay such interest, dividends or earnings to the Company, any Holder or any other party.

7.9 Entire Agreement. Notwithstanding the reference to any other agreement hereunder, this Agreement contains the entire understanding of the Parties hereto and thereto with reference to the transactions and matters contemplated hereby and thereby and supersedes all prior agreements, written or oral, among the Parties with respect hereto and thereto. If and to the extent that any provision of this Agreement is inconsistent or conflicts with the Merger Agreement, this Agreement will govern and control.

7.10 Applicable Law; Jurisdiction.
