Agreement and Plan of Merger

On May 16, 2021, Aerpio Pharmaceuticals, Inc., a Delaware corporation (“Aerpio”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) among Aerpio, Aadi Bioscience, Inc., a Delaware corporation (“Aadi”), and Aspen Merger Subsidiary, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of Aadi (“Merger Sub”), pursuant to which, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Aadi will be merged with and into Merger Sub (the “Merger”) at the effective time of the Merger (the “Effective Time”), with Aadi continuing after the Merger as the surviving company and a wholly-owned subsidiary of Aerpio. The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes.

At the Effective Time, each outstanding share of Aadi capital stock will be converted into the right to receive shares of Aerpio common stock, par value $0.001 (the “Aerpio Common Stock”), as set forth in the Merger Agreement. Under the exchange ratio formula in the Merger Agreement, immediately following the Effective Time, the former Aadi securityholders are expected to own approximately 66.8% of the outstanding shares of Aerpio Common Stock on a fully-diluted basis and securityholders of Aerpio as of immediately prior to the Effective Time are expected to own approximately 33.2% of the outstanding shares of Aerpio Common Stock on a fully-diluted basis (prior to giving effect to the PIPE Financing described below). Under certain circumstances further described in the Merger Agreement, the ownership percentages may be adjusted upward or downward based on the level of Aerpio’s net cash at the closing of the Merger. There can be no assurances as to Aerpio’s level of net cash between the signing of the Merger Agreement and closing.

In addition, as more fully described below, each holder of Aerpio Common Stock as of immediately prior to the Effective Time shall be entitled to one contractual contingent value right issued by Aerpio, subject to and in accordance with the terms and conditions of the CVR Agreement (as defined below), for each share of Aerpio Common Stock held by such holder. In connection with the Merger, Aerpio will assume all outstanding Aadi options, subject to appropriate adjustment of the number and exercise price based on the exchange ratio formula in the Merger Agreement.

The Merger Agreement contains a customary “no-shop” provision under which neither Aerpio nor Aadi is permitted to (i) solicit any alternative acquisition proposals, (ii) furnish any non-public information to any person in connection with or in response to any alternative acquisition proposal, (iii) engage in any negotiations or discussions with any person with respect to any alternative acquisition proposal, (iv) approve, endorse or recommend any alternative acquisition proposal, (v) execute or enter into any agreement relating to any alternative acquisition proposal, or (vi) publicly propose to do any of the foregoing. The “no-shop” provision is subject to certain exceptions that permit the board of directors of Aerpio Pharmaceuticals, Inc. (the “Aerpio Board”), to comply with its fiduciary duties, which, under certain circumstances, would enable Aerpio to provide information to, and enter into discussions or negotiations with, third parties in response to any alternative acquisition proposals.

The Merger Agreement contains customary representations, warranties and covenants made by Aadi and Aerpio, including covenants relating to obtaining the requisite approvals of the stockholders of Aadi and Aerpio, indemnification of directors and officers, and Aadi’s and Aerpio’s conduct of their respective businesses between the date of signing the Merger Agreement and the Effective Time.

The Merger Agreement provides each of Aerpio and Aadi with specified termination rights, and further provides that, upon termination of the Merger Agreement under specified circumstances, Aerpio may be required to pay the Aadi a termination fee of $2,000,000. In addition, in connection with certain terminations of the Merger Agreement, Aerpio may be required to pay Aadi’s out-of-pocket fees and expenses up to $750,000, which shall be credited against any termination fee which becomes payable thereafter.

The Merger Agreement provides that, immediately following the Effective Time, the board of directors of the combined company will consist of seven directors, comprised of three directors designated by Aadi, three directors designated by Aerpio and one director mutually agreed upon by Aadi and Aerpio (until each of their respective successors are duly elected or appointed and qualified or their earlier death, resignation or removal). Upon the closing of the transaction, the combined company will be led by Aadi’s chief executive officer. In connection with the Merger, Aerpio will seek to amend its certificate of incorporation to: (i) effect a reverse split of Aerpio Common Stock at a ratio to be determined by Aerpio and Aadi (if deemed necessary by the parties); (ii) change the name of Aerpio to “Aadi Bioscience, Inc.”; and (iii) make certain other changes that the Aerpio Board deems advisable and in the best interest of Aerpio.

The Aerpio Board has approved the Merger Agreement and the related transactions, and has adopted resolutions recommending that the requisite stockholders of Aerpio approve the issuance of shares of Aerpio Common Stock pursuant to the Merger and the issuance of shares of Aerpio Common Stock and Aerpio Pre-Funded Warrants in the PIPE Financing described below, and

approve the related amendments to Aerpio’s certificate of incorporation (the “Aerpio Stockholder Matters”). Aerpio has agreed to hold a stockholders’ meeting to submit the Aerpio Stockholder Matters to its stockholders for their consideration. In connection with the Merger, Aerpio intends to file a proxy statement with the Securities and Exchange Commission (“SEC”), with respect to the Aerpio Stockholder Matters (the “Proxy Statement”). Aadi stockholders holding the requisite amount of shares of the capital stock of Aadi have approved the Merger Agreement by written consent.

Aerpio’s and Aadi’s obligations to consummate the Merger are subject to the satisfaction or waiver of customary closing conditions, including, among others, obtaining the requisite approval of the Aerpio Stockholder Matters by the stockholders of Aerpio, Aerpio’s net cash not being less than $10,000,000 and the completion of the PIPE Financing described below.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about Aerpio or Aadi. The Merger Agreement contains representations, warranties and covenants that Aerpio and Aadi made to each other as of specific dates. The assertions embodied in those representations, warranties and covenants were made solely for purposes of the Merger Agreement between Aerpio and Aadi and may be subject to important qualifications and limitations agreed to by Aerpio and Aadi in connection with negotiating its terms, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Merger Agreement. Moreover, the representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to investors or security holders, or may have been used for the purpose of allocating risk between Aerpio and Aadi rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Aerpio’s public disclosures. For the foregoing reasons, no person should rely on the representations and warranties as statements of factual information at the time they were made or otherwise.

Stockholder Support Agreements

In connection with the execution of the Merger Agreement, Aerpio and Aadi entered into stockholder support agreements (the “Stockholder Support Agreements”) with Aerpio’s current directors and executive officers who collectively beneficially own or control an aggregate of approximately 1.3% of the outstanding shares of Aerpio Common Stock. The Aerpio Stockholder Support Agreements provide that, among other things, each of the stockholders has agreed to vote or cause to be voted all of the shares of Aerpio Common Stock beneficially owned by such stockholder in favor of the Aerpio Stockholder Matters at the Aerpio stockholders’ meeting to be held in connection with the Merger.

The foregoing description of the Aerpio Stockholder Support Agreements does not purport to be complete and is qualified in its entirety by reference to the form of the Aerpio Stockholder Support Agreement, which is provided as Exhibit A to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Lock-up Agreements

Concurrently and in connection with the execution of the Merger Agreement, Aerpio’s current directors who will serve on the board of directors of the combined company and certain stockholders of Aadi, which collectively beneficially own or control an aggregate of approximately 96.08% of Aadi’s voting securities, entered into lock-up agreements with Aerpio and Aadi, pursuant to which each stockholder will be subject to a 180 day lockup on the sale or transfer of shares of Aerpio Common Stock held by each such stockholder at the closing of the Merger, including those shares received by Aadi stockholders in the Merger (the “Lock-up Agreements”).

The foregoing description of the Lock-up Agreements does not purport to be complete and is qualified in its entirety by reference to the forms of the Lock-up Agreement, which are provided as Exhibits B and C to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Private Placement and Subscription Agreements

On May 16, 2021, Aerpio entered into Subscription Agreements (the “Subscription Agreements”) with the purchasers named therein (the “PIPE Investors”).

Pursuant to the Subscription Agreements, Aerpio agreed to sell shares of Aerpio Common Stock (in the form of shares of common stock and/or pre-funded warrants to acquire common stock of Aerpio (the “Aerpio Pre-Funded Warrants”)) for an aggregate purchase price of $155,000,000 (collectively, the “PIPE Financing”).

The closing of the PIPE Financing is expected to occur concurrently with, and is conditioned upon, the closing of the Merger. Following the closing of the PIPE Financing, the former Aadi securityholders are expected to own approximately 29.6% of the outstanding shares of Aerpio Common Stock on a fully-diluted basis, the securityholders of Aerpio as of immediately prior to the Effective Time of the Merger are expected to own approximately 14.7% of the outstanding shares of Aerpio Common Stock on a fully-diluted basis and the PIPE Investors are expected to own approximately 55.7% of the outstanding shares of Aerpio Common Stock on a fully-diluted basis.

The foregoing summary of the Subscription Agreements do not purport to be complete and is qualified in its entirety by reference to the Subscription Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Registration Rights Agreement

At the closing of the PIPE Financing, in connection with the Subscription Agreements, Aerpio intends to enter into a Registration Rights Agreement (the “Registration Rights Agreement”) with the PIPE Investors. Pursuant to the Registration Rights Agreement, Aerpio will prepare and file a resale registration statement with the SEC within 30 calendar days following the closing of the PIPE Financing (the “Filing Deadline”). Aerpio will use its reasonable best efforts to cause this registration statement to be declared effective by the SEC within 60 calendar days of the closing of the PIPE Financing (or within 90 calendar days if the SEC reviews the registration statement).

Aerpio will also agree among other things, to indemnify the Investors, their officers, directors, members, employees and agents, successors and assigns under the registration statement from certain liabilities and pay all fees and expenses (excluding any legal fees of the selling holder(s), and any underwriting discounts and selling commissions) incident to Aerpio’s obligations under the Registration Rights Agreement.

The PIPE Financing is exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and/or Regulation D promulgated thereunder, as a transaction by an issuer not involving a public offering. The PIPE Investors have acquired the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends have been affixed to the securities issued in this transaction.

The foregoing summary of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Registration Rights Agreement, which is provided as Exhibit C to the Subscription Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Contingent Value Rights Agreement

The Merger Agreement contemplates that, at or prior to the Effective Time, Aerpio, the Holder Representative (as defined therein) and the Rights Agent (as defined therein) will execute and deliver a contingent value rights agreement (the “CVR Agreement”), pursuant to which each holder of Aerpio Common Stock as of immediately prior to the Effective Time shall be entitled to one contractual contingent value right issued by Aerpio, subject to and in accordance with the terms and conditions of the CVR Agreement, for each share of Aerpio Common Stock held by such holder. Each contingent value right shall entitle the holder thereof to receive 90% of the net proceeds, if any, received by Aerpio pursuant to the Amended Gossamer License Agreement (as defined in Aerpio’s Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on March 11, 2021) and any agreement related to the Aspen Legacy Assets (as defined in the Merger Agreement) entered into prior to the Closing of the Merger. The contingent value rights are not transferable, except in certain limited circumstances as will be provided in the CVR Agreement, will not be certificated or evidenced by any instrument and will not be registered with the SEC or listed for trading on any exchange.

The foregoing description of the CVR Agreement does not purport to be complete and qualified in its entirety by reference to the form of CVR Agreement, which is provided as Exhibit E to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

The information in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

The shares to be issued by Aerpio in the Merger and the PIPE Investment will be issued in private placements exempt from registration under Section 4(a)(2) of the Securities Act, because the offer and sale of such securities does not involve a “public offering” as defined in Section 4(a)(2) of the Securities Act, and other applicable requirements were met.

The information in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

The information in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

On May 16, 2021, the Board amended Aerpio’s Amended and Restated By-laws in order to a new Section 11 of Article VI to designate the U.S. federal district courts as the exclusive jurisdiction for any litigation arising under the Securities Act (the “By-law Amendment”). The Board adopted the By-Law Amendment to reduce any potential expenses that Aerpio may incur in connection with any such actions or proceedings if it was required to defend any such potential actions or proceedings in multiple jurisdictions and/or in parallel proceedings in federal and state courts simultaneously.

The foregoing summary and description of the provisions of the By-law Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the By-law Amendment, a copy of which is filed as Exhibit 3.1 with this Current Report on Form 8-K and is incorporated herein by reference.

Furthermore, the information in Item 7.01 of this Current Report on Form 8-K, including the information in the press release attached as Exhibit 99.1 to this Current Report on Form 8-K, shall not be deemed to be incorporated by reference in the filings of Aerpio under the Securities Act.

2.5    Conversion of Shares.

(a)    At the Effective Time, by virtue of the Merger and without any further action on the part of Aspen, Merger Sub, the Company or any stockholder of the Company or Aspen:

(i)    any shares of Company Capital Stock held as treasury stock immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor; and

(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.

(c)    No fractional shares of Aspen Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued, with no cash being paid for any fractional share eliminated by such rounding.

(d)    All Company Options outstanding immediately prior to the Effective Time under the Company Plan shall be treated in accordance with Section 6.5.

(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.

(f)    If, between the time of calculating the Exchange Ratio and the Effective Time, the outstanding shares of Company Capital Stock or Aspen Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split (including the Nasdaq Reverse Split to the extent such split has not previously been taken into account in calculating the Exchange Ratio), combination or exchange of shares or other like change, the Exchange Ratio shall, to the extent necessary, be equitably adjusted to reflect such change to the extent necessary to provide the holders of Company Capital Stock, Company Options and Aspen Common Stock with the same economic effect as contemplated by this Agreement prior to such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or other like change; provided, however, that nothing herein will be construed to permit the Company or Aspen to take any action with respect to Company Capital Stock or Aspen Common Stock, respectively, that is prohibited or not expressly permitted by the terms of this Agreement.

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.

(b)    At or prior to the Effective Time, Aspen shall authorize and duly adopt, execute and deliver, and will ensure that Rights Agent (as defined in the CVR Agreement) execute and deliver, the CVR Agreement, subject to any reasonable revisions to the CVR Agreement that are requested by such Rights Agent (provided that such revisions are not, individually or in the aggregate, detrimental or adverse, taken as a whole, to any holder of CVR). Aspen and the Company shall cooperate, including by making changes to the form of CVR Agreement, as necessary to shall ensure that the CVRs are, and Aspen shall not issue or distribute any CVRs unless such issuance and distribution is, not subject to registration under the Securities Act, the Exchange Act or any applicable state securities or “blue sky” laws.

(c)    Aspen, the Rights Agent shall, at or prior to the Effective Time, duly authorize, execute and deliver the CVR Agreement.

2.7    Closing of the Company’s Transfer Books. At the Effective Time: (a) all shares of Company Capital Stock outstanding immediately prior to the Effective Time shall be treated in accordance with Section 2.5(a), and all holders of certificates representing shares of Company Capital Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Capital Stock outstanding immediately prior to the Effective Time. 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. If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of the Company, then the officers and directors of the Surviving Corporation shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of the Company, in the name of Merger Sub, in the name of the Surviving Corporation and otherwise) to take such action.

26

2.12    Intended Tax Treatment. For United States federal income tax purposes (and applicable state and local), the Merger is intended to constitute a reorganization within the meaning of Section 368(a) of the Code (the “Intended Tax Treatment”). The Parties adopt this Agreement as a “plan of reorganization” within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3.

2.13    Withholding. The Parties and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Capital Stock or any other Person such amounts as such Party or the Exchange Agent reasonably determines it is required to deduct and withhold under the Code or any other Law with respect to the making of such payment. To the extent that amounts are so withheld and paid 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.

Section 3. Representations and Warranties of the Company.

The Company is not under any obligation, nor is it bound by any Contract pursuant to which it may become obligated, to repurchase, redeem or otherwise acquire any outstanding shares of Company Common Stock or other securities. Section 3.6(b) of the Company Disclosure Schedule accurately and completely lists all repurchase rights held by the Company with respect to shares of Company Common Stock (including shares issued pursuant to the exercise of stock options) and specifies which of those repurchase rights are currently exercisable. Each share of Company Preferred Stock is convertible into one share of Company Common Stock.

(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.

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;

(v)    an incentive award plan and an employee stock purchase plan of Aspen in form and substance as agreed to by the Parties (the “2021 Plans”) each reserving for issuance an amount, to be determined by the Company in consultation with Aspen, of shares of Aspen Fully-Diluted Shares after giving effect to the Closing;

(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.

76

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.

77

6.6    Aspen Options.

(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. Each D&O Indemnified Party will be entitled to

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. Without otherwise limiting the D&O Indemnified Parties’ rights with regards to counsel, following the Effective Time, the D&O Indemnified Parties shall be entitled to continue to retain Goodwin Procter LLP or such other counsel selected by the D&O Indemnified Parties.

(b)    The provisions of the certificate of incorporation and bylaws of Aspen with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of Aspen that are presently set forth in the certificate of incorporation and bylaws of Aspen shall not be amended, modified or repealed for a period of six years from the Effective Time in a manner that would adversely affect the rights thereunder of individuals who, at or prior to the Effective Time, were officers or directors of Aspen, unless such modification is required by applicable Law. The certificate of incorporation and bylaws of the Surviving Corporation shall contain, and Aspen shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers as those presently set forth in the certificate of incorporation and bylaws of Aspen.

(c)    From and after the Effective Time, (i) the Surviving Corporation shall fulfill and honor in all respects the obligations of the Company to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under the Company’s Organizational Documents and pursuant to any indemnification agreements between the Company and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time and (ii) Aspen shall fulfill and honor in all respects the obligations of Aspen to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under Aspen’s Organizational Documents and pursuant to any indemnification agreements between Aspen and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time.

(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

79

(e)    From and after the Effective Time, Aspen shall pay all expenses, including reasonable attorneys’ fees, that are incurred by the persons referred to in this Section 6.9 in connection with their enforcement of the rights provided to such persons in this Section 6.9.

(f)    The provisions of this Section 6.9 are intended to be in addition to the rights otherwise available to the current and former officers and directors of Aspen and the Company by Law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, their heirs and their representatives.

(g)    In the event Aspen or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Aspen or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 6.9.

(e)    If either Party fails to pay when due any amount payable by it under this Section 10.3, then (i) such Party shall reimburse the other Party for reasonable costs and expenses (including reasonable fees and disbursements of counsel) incurred in connection with the collection of such overdue amount and the enforcement by the other Party of its rights under this Section 10.3 and (ii) such Party shall pay to the other Party interest on such overdue amount (for the period commencing as of the date such overdue amount was originally required to be paid and ending on the date such overdue amount is actually paid to the other Party in full) at a rate per annum equal to the “prime rate” (as announced by Bank of America or any successor thereto) in effect on the date such overdue amount was originally required to be paid plus three percent.

(f)    The Parties agree that, subject to Section 10.2, the payment of the fees and expenses set forth in this Section 10.3 shall be the sole and exclusive remedy of each Party following a termination of this Agreement under the circumstances described in this Section 10.3, it being understood that in no event shall either Aspen or the Company be required to pay the individual fees or damages payable pursuant to this Section 10.3 on more than one occasion. 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.

91

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.

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.

Exhibit A

Form of Aspen Stockholder Support 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:

(a)    If such Stockholder is an Entity: (i) such Stockholder is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it is incorporated, organized or constituted, (ii) such Stockholder has all necessary power and authority to execute and deliver this Agreement, to perform such Stockholder’s obligations hereunder and to consummate the transactions contemplated hereby, and (iii) the execution and delivery of this Agreement, performance of such Stockholder’s obligations hereunder and the consummation of the transactions contemplated hereby by such Stockholder have been duly authorized by all necessary action on the part of such Stockholder and no other proceedings on the part of such Stockholder are necessary to authorize this Agreement, or to consummate the transactions contemplated hereby. 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;

(f)    no investment banker, broker, finder or other intermediary is entitled to a fee or commission from Aspen or the Company in respect of this Agreement based upon any Contract made by or on behalf of such Stockholder; and

(g)    as of the date of this Agreement, there is no Legal Proceeding pending or, to the knowledge of such Stockholder, threatened against such Stockholder that would 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.

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.

4

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.

6

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.

For the avoidance of doubt, amounts placed in escrow or earnout, contingent or other post-closing payments, including milestone or royalty payments, in connection with the Covered Agreements will not be considered Net Proceeds unless (and only to the extent that) such amounts are actually received, and no longer subject to any contingency, by the Company prior to the CVR Term.

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.

(d) The permissive rights of the Rights Agent to do things enumerated in this Agreement will not be construed as a duty.

(e) The Rights Agent will not be required to give any note or surety in respect of the execution of its powers or otherwise under this Agreement.

(f) The Rights Agent will have no liability and shall be held harmless by the Company in respect of the validity of this Agreement or the execution and delivery herof (except the due execution and deliver hereof by the Rights Agent and the enforceability of this Agreement against the Rights Agent assuming the due execution and deliver hereof by the Company); nor shall it be responsible for any breach by the Company or any other Person of any covenant or condition contained in this Agreement.

(g) The Company agrees to indemnify the Rights Agent for, and to hold the Rights Agent harmless from and against, any loss, liability, damage, judgment, fine, penalty, cost or expense (each, a “Loss”) suffered or incurred by the Rights Agent and arising out of or in connection with the Rights Agent’s performance of its obligations under this Agreement, including the reasonable and documented costs and expenses of defending the Rights Agent against any claims, charges, demands, actions or suits arising out of or in connection in connection with the execution, acceptance, administration, exercise and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights

12

hereunder, except to the extent such Loss has been determined by a final non-appealable decision of a court of competent jurisdiction to have resulted from the Rights Agent’s fraud, gross negligence, bad faith or willful misconduct; provided that this Section 3.2(g) shall not apply with respect to income, receipt, franchise or similar Taxes. For avoidance of any doubt, any payments made by the Company under this Section 3.2(f) will be deducted from the CVR Payments.

(h) The Company agrees (i) to pay the fees of the Rights Agent in connection with the Rights Agent’s performance of its obligations hereunder, as agreed upon in writing by the Rights Agent and the Company on or prior to the date of this Agreement, and (ii) to reimburse the Rights Agent for all reasonable and documented out-of-pocket expenses and other documented disbursements incurred in the exercise and performance of its duties hereunder, including all stamp and transfer Taxes (and excluding for the avoidance of doubt, any income, receipt, franchise or similar Taxes) and governmental charges, incurred by the Rights Agent in the performance of its obligations under this Agreement, except that the Company will have no obligation to pay the fees of the Rights Agent or reimburse the Rights Agent for the fees of counsel in connection with any lawsuit initiated by the Rights Agent on behalf of itself or the Holders, except in the case of any suit enforcing the provisions of Section 2.4(a), Section 2.4(b) or Section 3.2(g), if the Company is found by a court of competent jurisdiction to be liable to the Rights Agent or the Holders, as applicable in such suit.

(i) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(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;

(l) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company or Aadi resulting from any such act, default, neglect or misconduct, absent gross negligence, bad faith or willful misconduct (each as determined by a final non-appealable judgment of a court of competent jurisdiction) in the selection and continued employment thereof.

13

(m) The Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement (except its countersignature thereof) or be required to verify the same, and all such statements and recitals are and shall be deemed to have been made by the Company only.

(n) The Rights Agent shall act hereunder solely as agent for the Company and shall not assume any obligations or relationship of agency or trust with any of the owners or holders of the CVRs. The Rights Agent shall not have any duty or responsibility in the case of the receipt of any written demand from any Holders with respect to any action or default by the Company, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or to make any demand upon the Company.

(o) The Rights Agent shall not be liable or responsible for any failure of the Company to comply with any of its obligations relating to this Agreement, including without limitation obligations under applicable regulation or law.

(p) The obligations of the Company and rights of the Rights Agent under this Section 3.2 and Section 2.4 shall survive the expiration of the CVRs and the termination of this Agreement and the resignation, replacement or removal of the Rights Agent.

(q) The Rights Agent may rely on and be fully authorized and protected in acting or failing to act upon (a) any guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program” or insurance program in addition to, or in substitution for, the foregoing; or (b) any law, act, regulation or any interpretation of the same even though such law, act, or regulation may thereafter have been altered, changed, amended or repealed.

3.3 Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice to the Company. Any such resignation notice shall specify the date on which such resignation will take effect (which shall be at least 45 days following the date that such resignation notice is delivered), and such resignation will be effective on the earlier of (x) the date so specified and (y) the appointment of a successor Rights Agent.

(b) The Company will have the right to remove the Rights Agent at any time by written notice to the Rights Agent, specifying the date on which such removal will take effect. Such notice will be given at least 30 days prior to the date so specified (or, if earlier, the appointment of the successor Rights Agent).

14

(c) If the Rights Agent resigns, is removed or becomes incapable of acting, the Company will promptly appoint a qualified successor Rights Agent. Notwithstanding the foregoing, if the Company fails to make such appointment within a period of 30 days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then the incumbent Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. The successor Rights Agent so appointed will, upon its acceptance of such appointment in accordance with this Section 3.3(c) and Section 3.4, become the Rights Agent for all purposes hereunder.

(d) The Company will give notice to the Holders of each resignation or removal of the Rights Agent and each appointment of a successor Rights Agent in accordance with Section 6.2. Each notice will include the name and address of the successor Rights Agent. If the Company fails to send such notice within ten Business Days after acceptance of appointment by a successor Rights Agent, the successor Rights Agent will cause the notice to be mailed at the expense of the Company.

(e) Notwithstanding anything to the contrary in this Section 3.3, unless consented to in writing by the Holder Representative, the Company will not appoint as a successor Rights Agent any Person that is not a stock transfer agent of national reputation or the corporate trust department of a commercial bank.

(f) The Rights Agent will reasonably cooperate with the Company and any successor Rights Agent in connection with the transition of the duties and responsibilities of the Rights Agent to the successor Rights Agent, including the transfer of all relevant data, including the CVR Register, to the successor Rights Agent, but such predecessor Rights Agent shall not be required to make any additional expenditure or assume any additional liability in connection with the foregoing.

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.

4. Covenants

4.1 List of Holders. The Company will furnish or cause to be furnished to the Rights Agent in such form as the Company receives from the Company’s transfer agent (or other agent performing similar services for the Company), the names and addresses of the Holders within ten Business Days of the Effective Time.

4.2 Payment. If any CVR Payment is due under Section 2.4(a), the Company will deposit the CVR Payment with the Rights Agent for payment to the Holders in accordance with Section 2.4(c).

15

4.3 Prohibited Actions.

(a) Notwithstanding anything to the contrary herein, the Company will not, and will cause its Subsidiaries to not, willfully and materially breach any of the material terms and conditions under any of the Covered Agreements in a manner that would reasonably be expected to be adverse to the interests of the Holders.

(b) The Company shall take no action for the principal purpose of (i) reducing the amount of any CVR Payment payable under this Agreement or (ii) restricting the Company’s ability to pay any of the CVR Payment hereunder.

4.4 Books and Records. The Company shall, and shall cause its Affiliates to, keep true, complete and accurate records in sufficient detail to enable the Holders and their consultants or professional advisors to confirm the applicable Payment Amount payable to each Holder hereunder in accordance with the terms specified in this Agreement.

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.

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.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder will affect the sufficiency of such notice with respect to other Holders.

7.3 The Company Successors and Assigns; Merger of Rights Agent.

(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. All funds received by the Rights Agent under this Agreement that are to be distributed or applied by the Rights Agent in the performance of services hereunder (the “Funds”) shall be held by the Rights Agent as agent for the Company and deposited in one or more bank accounts to be maintained by the Rights Agent in its name as agent for the Company. Until paid pursuant to the terms of this Agreement, the Rights Agent will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (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. 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 proceeding between the Parties arising out of or relating to this Agreement, each Party: (a) 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 United States District Court for the District of Delaware or, to the extent that neither of the foregoing courts has jurisdiction, the Superior Court of the State of Delaware; (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 7.10; (c) waives any objection to laying venue in any such action or proceeding in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party; (e) agrees that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 7.1 of this Agreement; and (f) irrevocably and unconditionally waives the right to trial by jury.
