Upon the written request of the Paid Party and not more than once in each calendar year, the Paying Party shall permit an independent certified public accounting firm of nationally recognized standing selected by the Paid Party and reasonably acceptable to the Paying Party to have access during normal business hours to such of the records of the Paying Party and its applicable Affiliates (and, as applicable, the Infinity Related Parties) as may be reasonably necessary to verify the accuracy of the payments due and costs incurred under this Agreement, including the royalty reports under this Agreement, for any period ending not more than three (3) years prior to the date of such request. The accounting firm shall disclose to the Paid Party only whether the payments due and costs incurred, including any payment reports (as applicable), are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to the Paid Party without the prior consent of the Paying Party unless disclosure is required by law, regulation or judicial order. If the Paid Party determines that disclosure is required by law, regulation or judicial order, it shall, if permitted, give the Paying Party prior notice thereof reasonably sufficient for the Paying Party to seek a protective order against or limiting such disclosure. The Paying Party is entitled to require the accounting firm to execute a reasonable confidentiality agreement prior to commencing any such audit.

The fees charged by such accounting firm shall be paid by the Paid Party; provided, however, that if the audit uncovers an underpayment by the Paying Party that exceeds five percent (5%) of the total payment owed, then the fees of such accounting firm shall be paid by the Paying Party unless the reason for such underpayment was a miscalculation on the part of the Paid Party. Any underpayments or unpaid amounts discovered by such audit or otherwise will be paid promptly by the Paying Party within thirty (30) days of the date the Paid Party delivers to the Paying Party such accounting firm’s written report, or as otherwise agreed upon by the Parties, plus interest calculated in accordance with Section 9.7 unless the reason for such underpayment was a miscalculation on the part of the Paid Party. In the event of an overpayment by the Paying Party, the Paying Party shall be entitled to credit such overpayment against any subsequent payment due to the Paid Party under this Agreement.

Payment. Payments shall be made by electronic wire transfer of immediately available funds to the account of the Paid Party, as designated in writing to the Paying Party.

Late Payments. Subject to Section 9.5(c), interest shall be payable by the Paying Party on any amounts payable to the Paid Party under this Agreement which are not paid by the due date for payment. All interest shall accrue and be calculated on a daily basis (both before and after any judgment) at a rate per annum equal to three (3) percentage points above the then current “prime rate” in effect published in The Wall Street Journal, Eastern Edition (but in no event in excess of the maximum rate permissible under applicable law), for the period from the due date for payment until the date of actual payment. The payment of such interest shall not limit the Paid Party from exercising any other rights it may have as a consequence of the lateness of any payment.

Other. Notwithstanding any other provision of this Agreement, if at any time legal restrictions prevent the prompt remittance of part or all of the payments required hereunder in any country, payment shall be made through such lawful means or methods as the Parties may agree. The Parties hereby acknowledge that the value contributed by Intellikine to any Product developed and/or commercialized by or on behalf of Infinity and its Affiliates, licensees and sublicensees is the access to the Intellikine Intellectual Property and that the Milestone Payments described above in Article 8 will be payable by Infinity in accordance with the terms and conditions hereof regardless of whether or not a Product is covered by an Intellikine Patent or, as applicable, Navy Patent Right or UCSF Patent Right.

INTELLECTUAL PROPERTY RIGHTS

Ownership of Inventions.

Ownership of all inventions arising from research, development or commercialization activities conducted by or on behalf of the Parties as contemplated by the Original Agreement or this Agreement, including Patent Rights and other intellectual property rights covering such inventions (collectively, “Inventions”), shall be as set forth in this Section 10.1. All Inventions made solely by employees, agents, contractors or consultants of Infinity or its Affiliates shall be owned by Infinity or its Affiliates. All Inventions made solely by employees, agents, contractors or consultants of Intellikine or Intellikine Program Affiliates shall be owned by Intellikine or its Affiliates; provided, however, that Intellikine, on behalf of itself and its Affiliates, shall, and hereby does, assign all of its and their right, title and interest in and to Intellikine Program Inventions and Intellikine Program Patents to Infinity. All Inventions made jointly by one or more employees, agents, contractors or consultants of

Intellikine’s rights in any Inventions, other than the Inventions assigned to Infinity pursuant to Section 10.1(a), shall be included in the Intellikine Intellectual Property for the purposes of this Agreement. Infinity’s rights in any Inventions, including its interest in any Inventions assigned to Infinity pursuant to Section 10.1(a), shall be included in the Infinity Intellectual Property for the purposes of this Agreement.

In the event of any disagreement between the Parties regarding the inventorship or ownership of any Invention, the Parties shall refer such dispute to a neutral Third Party patent attorney or other appropriately qualified person who is neither a current or former employee or director of, nor a current or former consultant or outside counsel to, either Party and who is mutually agreed upon by the Parties.

The provisions of Sections 10.2 through 10.7 are subject to the terms of any agreement pursuant to which a Third Party licensed any of the relevant Intellikine Patents to Intellikine. If Infinity exercises the Navy Sublicense Option or the UCSF Sublicense Option in accordance with Section 2.6(a) or 2.6(b), references in Sections 10.2 through 10.7 to Intellikine Patents will include the Navy Patent Rights or the UCSF Patent Rights (but not the UCSF Other Patent Rights), as applicable, subject to the rights of Navy under the Navy Agreement and to the rights of The Regents under the UCSF Agreement, respectively. Intellikine shall use reasonable efforts to cause such licensors to reasonably cooperate with Intellikine and Infinity with respect to such provisions and to join any suit brought by Infinity with respect to any Third Party Infringement.

Patent Prosecution.

Patent Committee.

Intellikine and Infinity will form a patent committee (“Patent Committee”) composed of one (1) representative from each Party and one (1) representative from each Party’s internal or outside patent counsel, as a forum to (A) keep Intellikine regularly and reasonably informed of the status of Intellikine Patents, and (B) provide Intellikine with copies of all substantive documentation submitted to, or received from, the patent offices in connection therewith. The Patent Committee shall meet as frequently as necessary for such purposes.

Decisions of the Patent Committee shall be made by unanimous vote, with Infinity’s representatives to the Patent Committee collectively having one (1) vote and Intellikine’s representatives to the Patent Committee collectively having one (1) vote.

To the extent that Intellikine wishes to have external patent counsel participate as one of its representatives on the Patent Committee, which counsel is not the then-current mutually acceptable outside patent counsel described in Section 10.2(b), Intellikine shall bear all expenses with respect to its external patent counsel’s participation as a representative on the Patent Committee.

Subject to Section 10.2(d), [**], at Infinity’s expense (which, with respect to Intellikine’s activities, shall be limited to Intellikine’s Out-of-Pocket Expenses), to file, prosecute and maintain the Intellikine Patents, using mutually acceptable outside patent counsel. As of the Effective Date, [**] are mutually acceptable to the Parties. Intellikine will assist Infinity in connection with the filing, prosecution and maintenance of the Intellikine Patents, including by providing access to relevant persons and executing all required documentation.

(i) Infinity will have the sole right to file, prosecute and maintain any Infinity Patents at its own expense. (ii) Intellikine will have the sole right to file, prosecute and maintain any Patents Rights within the Intellikine Additional Patents, the Intellikine Background Technology and the Intellikine Other Technology at its own expense. Intellikine will keep Infinity regularly and fully informed through the Patent Committee of the status of the patents and patent applications within the Intellikine Additional Patents, the Intellikine Background Technology and the Intellikine Other Technology.

In the event that (i) Infinity wishes to cease prosecution and/or maintenance of any Intellikine Patent in a country (ies) or (ii) Infinity does not wish to bear the costs with respect to the filing, prosecution or maintenance of an Intellikine Patent in a country(ies), Infinity shall provide Intellikine with prompt written notice thereof, and Intellikine shall have the right, in its discretion and at its own expense, to assume responsibility for the filing, prosecution and maintenance of such Intellikine Patent in such country(ies). If Intellikine assumes responsibility for the filing, prosecution and maintenance of such Intellikine Patent in such country(ies) or retains such responsibility, at its own expense, the license granted to Infinity under Section 2.1 under such Intellikine Patent in such country (ies) shall terminate. Infinity will provide such written notice to Intellikine in sufficient time (but no less than thirty (30) days before any statutory bar date) to permit Intellikine to file, prosecute or maintain such Intellikine Patent at its own expense.

Patent Infringement.

Each Party will promptly notify the other Party in writing of (i) any actual or threatened infringement or misappropriation by a Third Party of any Intellikine Patent or any Infinity Patent of which it becomes aware, as a result of such Third Party’s research, development, manufacture, use, sale, offer for sale, other commercialization or importation of Licensed Compounds or Products in the Field in the Territory, including any certification filed by a Third Party pursuant to 21 U.S.C. §355(b)(2)(A)(iv) or 355(j)(2)(A)(vii)(IV) or any notice under comparable U.S. or foreign law (a “Paragraph IV Certification”), which references the foregoing; or (ii) an actual or threatened challenge to any Intellikine Patent or Infinity Patent by a Third Party. The Parties will consult with each other through each Party’s patent attorneys to determine the response to any such infringement or challenge by a Third Party of any Intellikine Patent, including any Paragraph IV Certification which references the foregoing (collectively “Third Party Infringement”).

To the fullest extent possible under applicable law, Infinity will have the first right, but not the obligation, to initiate proceedings or take other appropriate action in connection with the Third Party Infringement as it reasonably determines appropriate, and Intellikine shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. Infinity may exercise such right itself or through any Infinity Related Party.

If Infinity fails to initiate proceedings or take other appropriate action with respect to, or to terminate, Third Party Infringement of any such Intellikine Patent (i) within ninety (90) days following Infinity’s receipt of the notice of alleged infringement or (ii) solely with respect to a Paragraph IV Certification, within

The Party conducting such action shall have full control over its conduct, including settlement thereof; provided, however, that, in no event shall either Party, through any court action or proceeding, any settlement arrangement or any proceeding, filing or communication with any patent office, admit the invalidity of, or otherwise impair the other Party’s rights in, any Intellikine Patent without the other Party’s prior written consent.

At the request of the Party controlling a Third Party Infringement action, the other Party shall provide reasonable assistance and cooperation in connection therewith, including by executing any required documents, participating in discovery (including producing laboratory notebooks and other documentation and providing access to employees or relevant persons), and joining as a party to the action if required. The Party controlling such Third Party Infringement action shall reimburse the reasonable Out-of-Pocket Expenses of such other Party incurred in providing such assistance within thirty (30) days after receipt of a detailed and accurate invoice therefor.

Unless otherwise agreed to by the Parties as part of any cost sharing arrangement, any recoveries resulting from an action relating to a claim of Third Party Infringement (after payment of Out-of-Pocket Expenses related to such action incurred by each Party) will be retained by the Party that brought and controlled such action; provided, however, that, if Infinity brought and controlled such action, any portion of such recovery (after payment of each Party’s Out-of-Pocket Expenses related to such action) that is attributable to lost profits with respect to Products shall be subject to a royalty payment to Intellikine in accordance with Section 8.3 equal to the amount that would be due if such amount were Net Sales under this Agreement.

Intellikine will have the sole right, but not the obligation, to initiate proceedings or take other appropriate action, as it reasonably determines appropriate, in connection with any actual or threatened infringement or misappropriation by a Third Party of any Intellikine Additional Patent, Intellikine Background Patent or Intellikine Other Technology at its own expense, shall have full control over its conduct, including settlement thereof, and shall retain any recoveries resulting from such action or proceeding.

Defense of Actions. In the event that a declaratory judgment or similar action alleging the invalidity or non-infringement, or any request for, or filing or declaration of, any interference, opposition, reissue or reexamination, of any Intellikine Patent or Infinity Patent is initiated by any Third Party, each Party will promptly notify the other and the rights and responsibilities for defending against any such action shall be determined in

Trademarks. Infinity shall have the right to brand the Products using Infinity related trademarks and trade names and any other trademarks and trade names it determines appropriate for the Product, which may vary by country or within a country (“Product Marks”). Infinity and, if applicable, certain Infinity Related Parties, shall own all right, title and interest in and to the Product Marks and Infinity or the Infinity Related Parties may file, seek registration and maintain the Product Marks in the countries and regions they determine reasonably necessary. Notwithstanding the foregoing, (i) with respect to any Product sold in the United States after receipt of Marketing Authorization for such Product in the United States, Infinity shall, to the extent permitted under applicable law and if reasonably practicable, include the Intellikine name or logo (“Intellikine Mark”) on the commercial packaging for such Product, and a disclosure that such Product is licensed from Intellikine, and (ii) Infinity and Infinity Related Parties may otherwise include the Intellikine Mark on the Product or any packaging, labels, containers, advertisements and other materials related thereto; provided, however, that any use of the Intellikine Mark shall be in compliance with Intellikine’s then-current reasonable trademark guidelines provided to Infinity. Intellikine hereby grants Infinity a non-exclusive, sublicenseable, royalty-free, transferrable (in accordance with Section 18.1) right to use the Intellikine Mark in connection with the foregoing. Intellikine or an Affiliate of Intellikine shall retain the ownership of the entire right, title and interest in and to the Intellikine Mark, and all goodwill associated with or attached to the Intellikine Mark arising out of the use thereof by Infinity, its Affiliates and sublicensees shall inure to the benefit of Intellikine. ▇▇▇▇▇▇▇▇ agrees that it will not contest, oppose or challenge Intellikine’s ownership of the Intellikine Mark. Infinity agrees that it will not at any time do or suffer to be done any act or thing that will in any way impair Intellikine’s ownership of or rights in and to the Intellikine Mark or any registration thereof or that may depreciate the value of the Intellikine Mark or the reputation of Intellikine.

Drug Price Competition and Patent Term Restoration Act.

Intellikine shall cooperate with Infinity in an effort to avoid loss of any Intellikine Patents which may otherwise be available under the provisions of the Drug Price Competition and Patent Term Restoration Act of 1984 or comparable United States or foreign laws, including by executing any documents as may be reasonably required. In particular, Intellikine shall cooperate with Infinity in obtaining patent term restoration or supplemental protection certificates or their equivalents in any country and region (“Patent Term Extensions”) where applicable to the Intellikine Patents. Intellikine shall provide all reasonable assistance to Infinity, including permitting Infinity to proceed with applications for such in the name of Intellikine, if so required.

After consultation by Infinity with Intellikine, Infinity shall have the sole right to determine, if applicable, for which, if any, of the Intellikine Patents the Parties will attempt to seek Patent Term Extensions for any Licensed Compound or Product.

Intellikine shall provide reasonable assistance to Infinity, including by executing any required documents and providing any relevant patent information and other relevant information to Infinity, so that Infinity can obtain such extensions and additional protection and inform the FDA or other Regulatory Authority of such intended Patent Term Extension.

Intellikine shall not seek Patent Term Extensions for any Intellikine Background Technology, Intellikine Additional Patents or Intellikine Other Patents for any Licensed Compound or Product.

Patent Marking. Infinity hereby agrees to mark each Product made, used or sold under the terms of this Agreement (or when the character of the product precludes marking, the package containing any such Product) in accordance with all applicable laws relating to patent marking.

EXCLUSIVITY

Exclusivity.

Intentionally Omitted

Intentionally Omitted

Subject to clauses (i) and (ii) below, Intellikine shall not, and Intellikine and its Affiliates shall ensure that the relevant individuals in clause (ii) below do not (in the course and duration of their employment by Intellikine or its Affiliates), alone or through work conducted in collaboration with an Affiliate or Third Party, research, develop, commercialize, distribute, market or sell (or license or otherwise grant rights to an Affiliate or a Third Party to do any of the foregoing) in the Territory in the Field, unless otherwise agreed by Infinity, [**]; provided that, the restriction described in this Section 11.1(c) will apply only as follows:

without limiting subsection (ii) below, [**] after the Effective Date (or the end of the Term, if earlier); and

[**].

Competing Products. In the event that Infinity is an Acquired Party in a transaction described in Section 18.1(a)(ii), to the extent that the Acquirer or any Acquirer Affiliate is then or later researching, developing or commercializing (or collaborating with a Third Party with respect thereto) a Target Inhibitor, such Target Inhibitor shall be considered a Licensed Compound and Product unless (i) such Acquirer and Acquirer Affiliates do not obtain rights or access (other than access in connection with due diligence prior to the transaction described in Section 18.1(a)(ii)) to (A) any Confidential Information of Intellikine and (B) the Intellikine Intellectual Property and, as applicable, Navy Patent Rights, UCSF Intellectual Property and UCSF Other Patent Rights; (ii) the Acquirer’s and all Acquirer Affiliates’ research, development, and commercialization activities related to such Target Inhibitor are kept separate from the research, development, and commercialization activities for Licensed Compounds and Products under this Agreement; and (iii) Infinity otherwise continues to meet its obligations under this Agreement.

CONFIDENTIALITY

Duty of Confidence. All Confidential Information disclosed or made available by a Party or its Affiliates to the other Party will be maintained in confidence and otherwise safeguarded by the recipient Party. For clarification, all Intellikine Intellectual Property shall be Confidential Information of Intellikine and all Infinity Intellectual Property shall be Confidential Information of Infinity; provided that (a) notwithstanding anything to the contrary in Section 12.2, Intellikine and its Affiliates may not rely on Sections 12.2(b) or (d) with respect to the Intellikine Program Patents or any Inventions assigned to Infinity pursuant to Section 10.1(a); and (b) Intellikine Know-How generated by or for Intellikine or Intellikine Program Affiliates, pursuant to and in accordance with the Original Agreement or this Agreement, which Know-How solely and specifically relates to Licensed Compounds and Products in the Field, shall be the Confidential Information of both Parties, with both Parties deemed to be recipient Parties and disclosing Parties. The recipient Party may only use the Confidential Information of the other Party and its Affiliates for the purposes of this Agreement and pursuant to the rights granted to the recipient Party under this Agreement. Each Party shall hold as confidential such Confidential Information of the other Party and its Affiliates in the same manner and with the same protection as such recipient Party maintains its own confidential information, but no less than a reasonable standard of care. A recipient Party may disclose Confidential Information of the other Party and its Affiliates to employees, agents, contractors, consultants and advisers of the recipient Party and its Affiliates and sublicensees to the extent reasonably necessary for the purposes of, and for those matters undertaken pursuant to, this Agreement; provided that such persons and entities are bound to maintain the confidentiality of the Confidential Information in a manner consistent with the confidentiality provisions of this Agreement.

Exceptions. The obligations under Section 12.1 shall not apply to any information to the extent the recipient Party can demonstrate by competent evidence that such information:

is (at the time of disclosure) or becomes (after the time of disclosure) known to the public or part of the public domain through no breach of the Original Agreement or this Agreement by the recipient Party or its Affiliates;

was known to, or was otherwise in the possession of, the recipient Party or its Affiliates prior to the time of disclosure by the disclosing Party;

is disclosed to the recipient Party or any of its Affiliates on a non-confidential basis by a Third Party who is entitled to disclose it without breaching any confidentiality obligation to the disclosing Party or any of its Affiliates; or

is independently developed by or on behalf of the recipient Party or its Affiliates, as evidenced by its written records, without reference to the Confidential Information disclosed by the disclosing Party or its Affiliates under the Original Agreement or this Agreement.

Authorized Disclosures.

In addition to disclosures allowed under Section 12.1, each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is necessary in the following instances: (i) filing or prosecuting Patent Rights as permitted by this Agreement; (ii) regulatory filings for Products such Party has a license or right to develop hereunder; (iii) prosecuting or defending litigation as permitted by this Agreement; (iv) complying with applicable court orders or governmental regulations; and (v) disclosure (A) to existing and potential consultants, investors, bankers, lawyers, accountants, agents or other Third Parties in connection with due diligence or similar investigations by such Third Parties, or (B) to existing and potential licensees or sublicensees, or (C) in the case of Infinity, disclosure of results of the Research Program and other research results to Third Parties as reasonably necessary to develop and commercialize Licensed Compounds and Products; provided, in each case described in clauses (v)(A) or (B), that any such consultant, investor, banker, lawyer, accountant, agent, licensee, sublicensee or Third Party is bound to maintain the confidentiality of the Confidential Information in a manner consistent with the confidentiality provisions of this Agreement.

In the event Infinity or any of its Affiliates discloses Intellikine Confidential Information to any Regulatory Authority to obtain Marketing Authorization for any Product and/or Licensed Compound, or discloses such information in connection with the filing of a patent application or the prosecution and maintenance of any patent, Infinity shall inform Intellikine as soon as reasonably practicable of the disclosure and use reasonable efforts to obtain confidential treatment for such disclosure to the extent permitted by law or regulation.

In the event the recipient Party is required to disclose Confidential Information of the disclosing Party by law, including to comply with any order of any court or governmental or regulatory authority, such disclosure shall not be a breach of this Agreement; provided that the recipient Party (i) informs the disclosing Party as soon as reasonably practicable of the required disclosure, (ii) takes all reasonable and lawful actions to obtain confidential treatment for such disclosure and limits the disclosure to the required purpose, and (iii) at the disclosing Party’s request and expense, assists in an attempt to object to or limit the required disclosure.

In the event of a disclosure of the Original Agreement or this Agreement or the terms hereof as required by law, governmental regulation or the rules of any recognized stock exchange or quotation system, the Parties shall coordinate with each other with respect to the timing, form and content of such required disclosure to the extent practicable under the circumstances, and, if so requested by the other Party, the Party subject to such obligation shall use reasonable commercial efforts to obtain an order protecting to the maximum extent possible the confidentiality of such provisions of this Agreement as reasonably requested by the other Party. If the Parties are unable to agree on the form or content of any required disclosure, such disclosure shall be limited to the minimum required, as determined by the disclosing Party in consultation with its legal counsel.

PUBLICATIONS; PUBLICITY

Publications. Any proposed oral public disclosures or written publications by Intellikine relating to a Product or a Licensed Compound (including results of the Research Program) shall require the written consent of Infinity prior to their release (which consent shall not be unreasonably withheld); provided, that the foregoing shall not apply to information which is not of a scientific or technical nature and which is in the public domain or any public disclosures required by law or governmental regulation or by the rules of any recognized stock exchange or quotation system. Each Party shall have the right to review and comment on any material proposed for disclosure or publication by the other Party, such as by oral presentation, manuscript or abstract, which includes Confidential Information of the non-publishing Party or, with respect to disclosures or publications proposed by Intellikine, relate to a Product or Licensed Compound (including results of the Research Program). Before any such material is submitted for publication, the Party proposing publication shall deliver a complete copy to the other Party at least thirty (30) days prior to submitting the material to a publisher or initiating any other disclosure (or if the Party proposing publication cannot reasonably provide such publication by such date, then as soon as practicable). Such other Party shall review any such material and give its comments to the Party proposing publication at least ten (10) days prior to the planned date of submission or disclosure (but in any event no fewer than ten (10) days after the delivery of such material to such other Party); provided, that such other Party shall make reasonable efforts to expedite review of such materials and abstracts, and shall return such items as soon as practicable to the Party proposing publication with appropriate comments, if any. The publishing Party shall comply with the other Party’s request to delete references to the other Party’s Confidential Information in any such material and agrees to delay any submission for publication or other public disclosure for a period of up to an additional forty-five (45) days for the purpose of preparing and filing appropriate patent applications.

Publicity. Each Party agrees not to issue any press release or other public statement, whether oral or written, disclosing the existence of the Original Agreement or this Agreement or the terms hereof without the prior written consent of the other Party. Subject to clause (c) below, the Party preparing any such public announcement shall provide the other Party with a draft thereof at least three (3) Business Days prior to the date on which such Party would like to make the public announcement. Notwithstanding the foregoing, (a) Infinity may issue the press release in substantially the form attached as Exhibit 8 to this Agreement as soon as practicable following the execution of this Agreement; (b) each Party will be permitted to disclose the achievement of Milestone Events and the payment of Milestone Payments, provided that the other Party is given the opportunity to review in advance (subject to clause (c) below) any such disclosure to ensure that no Confidential Information of that other Party is disclosed; (c) neither Party will be prevented from complying with any duty of disclosure it may have pursuant to law or governmental regulation or pursuant to the rules of any recognized stock exchange or quotation system; and (d) either Party may issue a press release or public announcement or make such other disclosure if the contents of such press release, public announcement or disclosure has previously been made public other than through a breach of this Agreement by the issuing Party or its Affiliates.

TERM AND TERMINATION

Term. The term of this Agreement (the “Term”) will commence on the Effective Date and continue until the earlier of (a) the termination of this Agreement in accordance with Section 6.3, 14.2, 14.3 or 14.4 or (b) the last to occur of (i) the expiry of the last-to-expire Valid Claim, or (ii) the expiration of the last-to-expire Royalty Term in accordance with Section 9.2.

Termination by Either Party.

If either Infinity or Intellikine (the “Breaching Party”) is in material breach of any material obligation hereunder, the other Party (the “Non-Breaching Party”) may give written notice to the Breaching Party specifying the claimed particulars of such breach, and in such event, if the breach is not cured within seventy-five (75) days after such notice (thirty (30) days in the event of failure to make any payment when due), the Non-Breaching Party shall have the right thereafter to terminate this Agreement immediately by giving written notice to the Breaching Party to such effect; provided, however, that if such breach (other than failure to make any payment when due) is capable of being cured but cannot be cured within such seventy-five (75) day period and the Breaching Party initiates actions to cure such breach within such period and thereafter diligently pursues such actions, the Breaching Party shall have such additional period as is reasonable in the circumstances to cure such breach.

In the event the Non-Breaching Party gives notice to the Breaching Party pursuant to Section 14.2(a) as a result of a material breach (or alleged material breach) by the Breaching Party and, on or before the end of the cure period therefor set forth above, either Party has requested an arbitration pursuant to Section 18.5 in which the Breaching Party is in good faith disputing such basis for termination pursuant to Section 14.2(a), then this Agreement shall not terminate unless and until such arbitrators issue a final ruling or award upholding such basis for termination (or unless and until the Breaching Party is no longer disputing such basis in good faith, if earlier).

Termination by Intellikine. Intellikine shall have the right to terminate this Agreement upon thirty (30) days written notice to Infinity if Infinity or any Infinity Related Party brings an action or proceeding that disputes the validity of any of the Intellikine Patents or files an opposition (or any equivalent action) against any of the Intellikine Patents in any country of the Territory. Any such termination shall only become effective if Infinity or such Infinity Related Party, as applicable, has not withdrawn such action before the end of the above notice period.

Termination for Convenience. Infinity may terminate this Agreement in its entirety at any time on one hundred eighty (180) days’ prior written notice to Intellikine.

EFFECT OF TERMINATION

Effect of Termination. Upon any expiration or termination of this Agreement, any licenses granted by either Party to the other Party will terminate and revert to the granting Party; provided that (a) in the case of any expiration or termination of this Agreement, any license granted under Section 15.2(a) or (b), if applicable, will continue in accordance with its terms, (b) in the case of any expiration of this Agreement or termination of this Agreement by Infinity under Section 14.2, any license described in Section 9.2(b) then in effect will continue in effect on a perpetual and irrevocable basis, and (c) the licenses and sublicenses granted by Intellikine to Infinity under Sections 2.1(a) and 2.1(d)(ii) and (iii) and, if Infinity has exercised the Navy Sublicense Option and the UCSF Sublicense Option, respectively, Sections 2.1(b) and 2.1(c), will continue in effect solely to the extent and during the period necessary for Infinity to exercise its rights or perform its obligations under Sections 15.2(d), 15.2(f) or Section 15.3(a). If this Agreement terminates prior to full and complete payment of the Release Payment, within thirty (30) days after the effective date of such termination, Infinity shall pay to Intellikine any portion of the Release Payment not previously paid.

Effects of Termination by Intellikine under Section 6.3, 14.2 or 14.3 or by Infinity under Section 14.4. Upon termination of this Agreement by Intellikine pursuant to Section 6.3, 14.2 or 14.3 or by Infinity pursuant to Section 14.4:

Infinity shall, and it hereby does (effective only and automatically upon such termination), grant to Intellikine a non- exclusive, worldwide, fully-paid, irrevocable, perpetual and transferrable (in accordance with Section 18.1) license, including the right to sublicense, under Infinity’s interest in the Infinity Know-How, to develop, make, have made, use, sell, have sold, offer for sale and import any then-identified Licensed Compounds (“Reverted Compounds”), and Products containing Reverted Compounds (“Reverted Products”), in the Field in the Territory;

For termination under Section 6.3, Infinity shall, and it hereby does (effective only and automatically upon such termination), grant to Intellikine a non-exclusive, worldwide, royalty-bearing, transferrable (in accordance with Section 18.1) license, including the right to sublicense, under the Infinity Patents and Infinity Know-How (including, for the sake of clarity, any Joint Patents and Joint Know-How), to develop, make, have made, use, import, offer for sale and sell any Reverted Compounds and Reverted Products, subject to a royalty obligation to Infinity on Infinity Patents and Infinity Know-How (other than Joint Patents, Joint Know-How, Intellikine Program Patents and Intellikine Program Inventions), which royalty obligation, if applicable, will be negotiated in good faith by the Parties for a period of [**] days immediately following such termination of the Agreement by Intellikine, which royalty shall not exceed [**] percent ([**]%) of Net Sales (applied to Intellikine in the same manner as applied to Infinity). For termination by Intellikine under Section 6.3, 14.2 or 14.3 or by Infinity under Section 14.4, Intellikine will have an exclusive right of first negotiation, exercisable by written notice to Infinity at any time within [**] days of such termination, to obtain a worldwide, exclusive, royalty-bearing license, with the right to sublicense, under the Infinity Patents and Infinity Know-How (except for the case of any Joint Patents, Joint Know- How, Intellikine Program Patents and Intellikine Program Inventions with respect to which Infinity had automatically granted the royalty-free license described above in this clause (b)), to develop, make, have made, use, sell, have sold, offer for sale and import Reverted Compounds and Reverted Products in the Field in the Territory on commercially reasonable terms to be negotiated in good faith by the Parties for up to an additional [**] days following exercise of such right of first negotiation;

For the sake of clarity, any license granted to Intellikine as described in Section 15.2(a) or (b) will include the right to use clinical and regulatory data and information generated by or on behalf of Infinity or its Affiliates and in Infinity’s or its Affiliates’ possession or control for regulatory purposes relating to the Reverted Products;

in the event that any development activities with regard to Reverted Compound(s) or Reverted Product(s) are ongoing at the time of such termination, the Parties shall negotiate in good faith and adopt a plan to wind-down the development activities in an orderly fashion (not to exceed [**] months) or, at Intellikine’s election, promptly transition such development activities to Intellikine or its designee, with due regard for patient safety and the rights of any subjects that are participants in any clinical trials of any Reverted Compound or Reverted Product, and take any actions it deems reasonably necessary or appropriate to avoid any human health or safety problems and in compliance with all applicable laws; all such activities shall be at Intellikine’s cost;

the exclusive license, if any, and any exclusive license agreement entered into as described in Section 15.2(b) will provide for Infinity to transfer and assign to Intellikine all of Infinity’s and the Infinity Related Parties’ right, title and interest in and to all U.S. and foreign regulatory submissions and Marketing Authorizations with respect to the Reverted Products and all drug master files and drug dossiers with respect to the Reverted Products (other than those related to manufacturing facilities);

Infinity or Infinity Related Parties may continue, to the extent that Infinity or Infinity Related Parties continue to have stocks of usable Products, to fulfill orders received for Reverted Products in the Field until [**] months following the date of termination. For Reverted Products sold by Infinity or Infinity Related Parties after the effective date of a termination, Infinity shall continue to pay Royalties pursuant to Section 8.3. Prior to the end of such [**] month period, Infinity shall provide Intellikine written notice of an estimate of the quantity of Reverted Products and shelf life remaining in the inventory of Infinity at the end of such [**] month period and Intellikine shall have the right to purchase any such quantities of Products from Infinity at a price equal to [**] for such Reverted Products. In addition, Infinity shall use reasonable efforts to transition to Intellikine, upon Intellikine’s request and at Intellikine’s expense, any arrangement with any contractor from which Infinity had arranged to obtain supplies of Reverted Compounds or Reverted Products, to the extent permitted under any such agreement with such contractor. In the event that Reverted Compounds or Reverted Products are then being manufactured by Infinity, then, upon request by Intellikine, Infinity shall continue to provide Intellikine with such materials at a price equal to [**] for such Reverted Products for not longer than [**] months;

the provisions of Article 12 shall survive such termination for so long as Intellikine or any of its Affiliates, licensees or sublicensees develops or commercializes any Reverted Compound or Reverted Product;

except as provided in Sections 15.2(d) and 15.2(f), Infinity will immediately cease to use or exploit in any way the Reverted Products, the Intellikine Marks, the Intellikine Intellectual Property, Intellikine Additional Patents, Intellikine Background Technology and Intellikine Other Technology (and, if Infinity has exercised the Navy Sublicense Option and the UCSF Sublicense Option, the Navy Patent Rights and the UCSF Intellectual Property and UCSF Other Patent Rights); provided that Infinity retains its right to use or exploit its ownership interest in Infinity Intellectual Property (including Joint Patents and Joint Know-How), subject to any exclusive license granted thereunder to Intellikine as described in Section 15.2(b);

except as provided in Section 15.2(a), (b), (c), (d), (e) and (f), Intellikine will immediately cease to use or exploit in any way the Product Marks and the Infinity Intellectual Property;

within thirty (30) days of the date of such termination, Infinity will make all outstanding payments, including any royalty payments, due to Intellikine hereunder at the date of such termination; and

following the period set forth in Section 15.2(f), Infinity will promptly return, or at Intellikine’s option, destroy any Intellikine Know-How, Intellikine Background Know-How, UCSF Know-How (if Infinity has exercised the UCSF Sublicense Option) and Intellikine Confidential Information and any materials containing the Intellikine Know- How, Intellikine Background Know-How, UCSF Know-How (if Infinity has exercised the UCSF Sublicense Option) or Intellikine Confidential Information in its or its Affiliates’ possession, custody or power, except for such records as may be required to be retained by Infinity by any national or local laws, rules or regulations.

Effect of Termination by Infinity under Section 14.2. In the event of termination of this Agreement by Infinity under Section 14.2:

Infinity and the Infinity Related Parties shall be entitled to continue to sell existing stocks of the Products in the Territory for a period of not longer than six (6) months following the date of termination; provided that, Infinity pays Intellikine any Royalties due in respect of such sales in accordance with the provisions of this Agreement;

except as provided in Sections 9.2(b) and 15.3(a), Infinity will immediately cease to use or exploit in any way the Intellikine Marks and the Intellikine Intellectual Property, Intellikine Additional Patents, Intellikine Background Technology and Intellikine Other Technology (and, if Infinity has exercised the Navy Sublicense Option and the UCSF Sublicense Option, the Navy Patent Rights and the UCSF Intellectual Property and UCSF Other Patent Rights), and Intellikine will immediately cease to use or exploit in any way the Infinity Intellectual Property; and

following the period set forth in Section 15.3(a), Intellikine will promptly return, or at Infinity’s option, destroy any Infinity Know-How and Infinity Confidential Information (other than data generated with respect to Licensed Compounds or Products in the conduct of the Research Program, which shall thereafter be considered to be Intellikine Confidential Information) and any materials containing the Infinity Know-How or such Infinity Confidential Information in its or its Affiliates’ possession, custody or power, except for such records as may be required to be retained by Intellikine by any national or local laws, rules or regulations.

Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination, nor affect in any way the survival of any other right, duty or obligation of the Parties which is expressly stated elsewhere in this Agreement to survive such termination or expiry. Without limiting the foregoing, Articles 1, 15 (including the additional sections that survive in accordance with the express terms of Section 15) and 18 and Sections 9.2 (b), 9.2(d), 9.5, 10.1, 13.2, 16.6, 17.1, 17.2, 17.3 and 17.4 shall survive expiration or termination of this Agreement. The provisions of Article 12 (Confidentiality) shall survive the termination or expiration of this Agreement for a period of ten (10) years (subject to Section 15.2(g)) and the provisions of Section 17.5 (Insurance) shall survive the termination or expiration of this Agreement for a period of six (6) years. For the sake of clarity, Article 11 shall not survive expiration or termination of this Agreement.

Exercise of Right to Terminate. The use by either Party of a termination right provided for under this Agreement shall not give rise to the payment of damages or any other form of compensation or relief to the other Party solely with respect thereto.

Damages; Relief. Subject to Sections 15.4 and 15.5 above, termination of this Agreement shall not preclude either Party from claiming any other damages, compensation or relief that it may be entitled to upon such termination.

Intentionally Omitted

Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Infinity or Intellikine are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that each Party, as a licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code.

INDEMNIFICATION AND LIABILITY

Indemnification by Intellikine. Intellikine shall indemnify and hold Infinity and its Affiliates, and their respective officers, directors, employees, contractors, agents and assigns (each, an “Infinity Indemnified Party”), harmless from and against losses, damages and liability, including reasonable legal expense and attorneys’ fees (collectively, “Indemnified Losses”), incurred by any Infinity Indemnified Party as a result of any Third Party demands, claims or actions (including product liability claims) (“Claims”) against any Infinity Indemnified Party to the extent arising or resulting from: (a) the negligence or willful misconduct of Intellikine or any Intellikine Indemnified

Indemnification by Infinity. Infinity shall indemnify and hold Intellikine and its Affiliates, and their respective officers, directors, employees, contractors, agents and assigns (each, an “Intellikine Indemnified Party”), harmless from and against Indemnified Losses incurred by any Intellikine Indemnified Party as a result of any Claims against any Intellikine Indemnified Party to the extent arising or resulting from: (a) the research, development or commercialization of the Licensed Compounds and/or Products by Infinity, any Infinity Indemnified Party or any Infinity Related Party; (b) the negligence or willful misconduct of Infinity or any Infinity Related Party in performing Infinity’s obligations or exercising Infinity’s rights under the Original Agreement or this Agreement; (c) the breach of any of the covenants, warranties and representations made by Infinity to Intellikine under the Original Agreement or this Agreement; or (d) if Infinity does not exercise the Navy Sublicense Option or the UCSF Sublicense Option under Section 2.6(a) or 2.6(b), respectively, the practice, use, infringement or misappropriation of any Navy Patent Rights or any UCSF Intellectual Property or UCSF Other Patent Right, as applicable, in the research, development or commercialization of the Licensed Compounds and/or Products. Notwithstanding the foregoing, Infinity shall not be responsible for the indemnification of any Intellikine Indemnified Party: (A) to the extent that the Indemnified Losses of such Intellikine Indemnified Party were caused by the negligence or willful misconduct of such Intellikine Indemnified Party, or (B) to the extent that the Indemnified Losses of such Intellikine Indemnified Party were caused by any breach by Intellikine of its covenants, obligations, warranties or representations pursuant to the Original Agreement or this Agreement.

Indemnification Procedure.

Any Infinity Indemnified Party or Intellikine Indemnified Party seeking indemnification hereunder (“Indemnified Party”) shall notify the Party against whom indemnification is sought (“Indemnifying Party”) in writing reasonably promptly after the assertion against the Indemnified Party of any Claim in respect of which the Indemnified Party intends to base a claim for indemnification hereunder, but the failure or delay so to notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation or liability that it may have to the Indemnified Party except to the extent that the Indemnifying Party’s ability to defend or resolve such Claim is adversely affected thereby.

Subject to the provisions of Sections 17.3(d) and (e) below, the Indemnifying Party shall have the right, upon written notice given to the Indemnified Party within thirty (30) days after receipt of the notice from the Indemnified Party of any Claim, to assume the defense and handling of such Claim, at the Indemnifying Party’s sole expense, in which case the provisions of Section 17.3(c) below shall govern.

If the Indemnifying Party assumes the defense and handling of such Claim: The Indemnifying Party shall select counsel reasonably acceptable to the Indemnified Party in connection with conducting the defense and handling of such Claim, and the Indemnifying Party shall defend or handle the same in consultation with the Indemnified Party, and shall keep the Indemnified Party timely apprised of the status of such Claim. The Indemnified Party shall not settle such Claim without the prior written consent of the Indemnifying Party. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, agree to a settlement of such Claim which could lead to liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder, or would involve any admission of wrongdoing on the part of the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party, at the request and expense of the Indemnifying Party, and shall be entitled to participate in the defense and handling of such Claim with its own counsel and at its own expense. Notwithstanding the foregoing, in the event the Indemnifying Party fails to conduct the defense and handling of any Claim in good faith after having assumed such, then the provisions of Section 17.3 (e) below shall govern.

If the Indemnifying Party does not give written notice to the Indemnified Party, within thirty (30) days after receipt of the notice from the Indemnified Party of any Claim, of the Indemnifying Party’s election to assume the defense and handling of such Claim, the provisions of Section 17.3(e) below shall govern.

Unless Section 17.3(c) applies: The Indemnified Party may, at the Indemnifying Party’s expense, select counsel reasonably acceptable to the Indemnifying Party in connection with conducting the defense and handling of such Claim and defend or handle such Claim in such manner as it may deem appropriate; provided, however, that the Indemnified Party shall keep the Indemnifying Party timely apprised of the status of such Claim and shall not settle such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. The Indemnifying Party shall not settle such Claim without the prior written consent of the Indemnified Party. If the Indemnified Party defends or handles such Claim, the Indemnifying Party shall cooperate with the Indemnified Party, at the Indemnified Party’s request but at no expense to the Indemnified Party, and shall be entitled to participate in the defense and handling of such Claim with its own counsel and at its own expense.

In the event a Claim is based partially on an indemnified claim and partially on a non-indemnified claim or based partially on a claim indemnified by one Party and partially on a claim indemnified by the other Party, any payments in connection with such Claim shall be apportioned between the Parties in accordance with the degree of cause attributable to each Party.

Nothing in this Section 17 will act to negate any obligation under common law of either Party to mitigate damages with respect to any Claim for which such Party is seeking indemnification from the other Party hereunder.

Special, Indirect and Other Losses. IN NO EVENT SHALL EITHER PARTY OR ANY OF ITS AFFILIATES BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL DAMAGES OR LOSS OF PROFITS SUFFERED BY THE OTHER PARTY, EXCEPT FOR LIABILITY FOR (A) BREACH OF ARTICLE 12 OF THE ORIGINAL AGREEMENT OR THIS AGREEMENT, OR (B) TO THE EXTENT ANY SUCH DAMAGES ARE REQUIRED TO BE PAID TO A THIRD PARTY PURSUANT TO SECTIONS 17.1 THROUGH 17.3 AS PART OF A CLAIM (AS DEFINED IN SECTION 17.1). IN NO EVENT WILL PAYMENTS DUE UNDER SECTION 8 BE CONSIDERED LOST PROFITS.

Insurance. Each Party, at its own expense, shall maintain liability insurance (or self-insure) with respect to its activities hereunder in an amount consistent with industry standards. Each Party shall provide a certificate of insurance (or evidence of self-insurance) evidencing such coverage to the other Party upon request. Without limitation of the foregoing, during the Term and thereafter for the period of time required below, Infinity shall maintain on an ongoing basis comprehensive general liability insurance in the minimum amount of $[**] per occurrence and $[**] annual aggregate combined single limit for bodily injury and property damage liability; and products liability insurance (including contractual liability coverage on Infinity’s indemnification obligations under this Agreement) in the amount of at least $[**] per occurrence and as an annual aggregate combined single limit for bodily injury and property damage liability; provided, however, that, commencing not later than [**] by Infinity or any Infinity Related Party, and thereafter for the period of time required below, Infinity shall obtain and maintain on an ongoing basis products liability insurance (including contractual liability coverage on Infinity’s indemnification obligations under this Agreement) in the amount of at least $[**] per occurrence and as an annual aggregate combined single limit for bodily injury and property damage liability. All of such insurance coverage may be maintained through a self insurance plan that substantially complies with the foregoing limits and requirements and may be satisfied through one or more policies, including an umbrella policy. Not later than thirty (30) days following receipt of written request from Intellikine, Infinity shall provide to Intellikine a letter(s) affirming appropriate self-insurance and/or a Certificate of Insurance evidencing such coverage in accordance with this Agreement. Thereafter, Infinity shall maintain such

GENERAL PROVISIONS

Assignment.

Neither Party may assign its rights and obligations under this Agreement without the other Party’s prior written consent, except that (i) either Party may assign its rights and obligations under this Agreement or any part hereof to one or more of its Affiliates without the consent of any other Party, provided that the assigning Party shall remain liable and responsible to the non-assigning Party for the performance and observance of all such duties and obligations by such Affiliate; and (ii) either Party may assign this Agreement in its entirety to a Third Party successor to all or substantially all of its business relating to Licensed Compounds and Products, whether by merger, sale of stock, sale of assets or otherwise and whether this Agreement is actually assigned or is assumed by the acquirer by operation of law, including in the context of a reverse triangular merger. The assigning Party shall provide the other Party with prompt written notice of any such assignment. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Any attempted assignment in contravention of the foregoing shall be void.

In connection with a transaction described in Section 18.1(a)(ii) with respect to a transaction that occurs at any time after the Original Effective Date (with respect to the corporate structure of the Acquired Party (as defined below) as it existed on the Original Effective Date or at the relevant time thereafter): (1) the “Acquired Party” means the Party that is a party to such transaction; (2) the “Acquired Party Pre-Existing Affiliates” means the Affiliates of the Acquired Party existing immediately prior to the closing of such transaction; (3) the “Acquirer” means the acquiring Third Party in such transaction; (4) the “Acquirer Affiliates” means all Affiliates of the Acquirer other than, following such transaction, the Acquired Party and the Acquired Party Pre-Existing Affiliates; and (5) “Non- Acquired Party” means the Party that is not a party to such transaction.

Performance by Affiliates. Any obligation of Infinity under or pursuant to this Agreement may be satisfied, met or fulfilled, in whole or in part, at Infinity’s sole and exclusive option, either by Infinity directly or by any Affiliate of Infinity that Infinity causes to satisfy, meet or fulfill such obligation, in whole or in part. Any obligation of Intellikine under or pursuant to this Agreement may be satisfied, met or fulfilled, in whole or in part, at Intellikine’s sole and exclusive option, either by Intellikine directly or by any Affiliate of Intellikine that Intellikine causes to satisfy, meet or fulfill such

Severability. Should one or more of the provisions of this Agreement become void or unenforceable as a matter of law, then this Agreement shall be construed as if such provision were not contained herein and the remainder of this Agreement shall be in full force and effect, and the Parties will use their best efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision which conforms as nearly as possible with the original intent of the Parties.

Governing Law. This Agreement shall be governed by and construed under the laws of the State of New York, USA, without giving effect to the conflicts of laws provision thereof.

Dispute Resolution.

The Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising from or related to this Agreement or the breach thereof. If the Parties cannot resolve the dispute, controversy or claim (other than any such matter to be resolved by the Patent Committee, which shall not be subject to this Section 18.5 but shall be resolved solely pursuant to the procedures set forth in Article 10 (except with respect to any disputes not resolved as a result of the proviso in Section 10.2(a)(ii)(B)) within thirty (30) days of a written request by either Party to the other Party, the Parties agree to hold a meeting, attended by the Senior Officers (or their designee with executive authority), as appropriate in light of the subject matter of the dispute, to attempt in good faith to negotiate a resolution of the dispute prior to pursuing other available remedies. If, within thirty (30) days after such written request, the Parties have not succeeded in negotiating a resolution of the dispute, and a Party wishes to pursue the matter, each such dispute, controversy or claim that is not an Excluded Claim shall be resolved by binding arbitration in accordance with the Commercial Arbitration Rules and Supplementary Procedures for Large Complex Disputes of AAA as then in effect, and judgment on the arbitration award may be entered in any court having jurisdiction thereof; provided, however, that a Party may pursue any matter described under Section 18.6 as described therein. The decision rendered in any such arbitration will be final and not appealable. If either Party intends to commence binding arbitration of such dispute, controversy or claim, such Party will provide written notice to the other Party informing the other Party of such intention and the issues to be resolved. Within thirty (30) days after the receipt of such notice, the other Party may by written notice to the Party initiating binding arbitration, add additional issues which meet the criteria in the second (2nd) sentence of this Section 18.5(a) (and are not Excluded Claims), to be resolved.

The arbitration shall be conducted by a panel of three (3) persons experienced in the pharmaceutical business, none of whom shall be a current or former employee or director, or a then-current stockholder, of either Party, their respective Affiliates or any other Infinity Related Party. Within thirty (30) days after receipt of the original notice of binding arbitration (the “Notice Date”), each Party shall select one person to act as arbitrator and the two Party- selected arbitrators shall select a third arbitrator within ten (10) Business Days of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the AAA. The place of arbitration shall be New York, New York, and all proceedings and communications shall be in English.

It is the intention of the Parties that discovery, although permitted as described herein, will be limited except in exceptional circumstances. The arbitrators will permit such limited discovery necessary for an understanding of any legitimate issue raised in the arbitration, including the production of documents. No later than thirty (30) days after selection of the third arbitrator, the Parties and their representatives shall hold a preliminary meeting with the arbitrators, to mutually agree upon and thereafter follow procedures seeking to assure that the arbitration will be concluded within six (6) months from such meeting. Failing any such mutual agreement, the arbitrators will design and the Parties shall follow procedures to such effect.

The arbitrators will, in rendering their decision, apply the substantive law of the State of New York, without giving effect to its principles of conflicts of law, and without giving effect to any rules or laws relating to arbitration.

Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other non- compensatory damages, except as may be permitted by Section 17.4. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ and any administrative fees of arbitration.

Except to the extent necessary to confirm or enforce an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable New York statute of limitations.

As used in this Section, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns the validity, enforceability or infringement of a patent, trademark or copyright.

Injunctive Relief. Each Party acknowledges and agrees that, due to the unique and valuable nature of the other Party’s Confidential Information, there would be no adequate remedy at law for any breach by such Party of Section 11.1(c), the proviso in Section 16.4(g), Article 12 or Article 13, that any such breach may result in irreparable harm to the other Party for which monetary damages would be inadequate to compensate such party and that the other Party shall have the right, in addition to any other rights available under applicable law, to obtain from any court of competent jurisdiction injunctive relief to restrain any breach or threatened breach of, or otherwise to specifically enforce, any covenant or obligation of such Party under such provisions, without the necessity of posting any bond or security.

Force Majeure. Neither Party shall be responsible to the other for any failure or delay in performing any of its obligations under this Agreement or for other nonperformance hereunder (excluding, in each case, the obligation to make payments when due) if such delay or nonperformance is caused by strike, fire, flood, earthquake, accident, war, act of terrorism, act of God or of the government of any country or of any local government, or by cause unavoidable or beyond the reasonable control of such Party. In such event, the Party affected will use commercially reasonable efforts to resume performance of its obligations.

Waivers and Amendments. The failure of any Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party. No waiver shall be effective unless it has been given in writing and signed by the Party giving such waiver. No provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party.

Relationship of the Parties. Nothing contained in this Agreement shall be deemed to constitute a partnership, joint venture, or legal entity of any type between Intellikine and Infinity, or to constitute one as the agent of the other. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give any Party the power or authority to act for, bind, or commit the other.

Notices.
