EXECUTION VERSION

3.7Right of First Refusal. If at any time prior to the date which is ninety (90) days subsequent to the Initial Results Date (such period, the “ROFR Offer Period”) Five Prime determines that it wishes to out-license the right to commercialize the Five Prime CSF1R Program in any territory, Five Prime will promptly notify BMS in writing of same and the territory as to which the license will cover, and BMS will have the exclusive right to negotiate for the right to obtain an exclusive license to develop and commercialize the Five Prime CSF1R Program in such territory (the “Right of First Refusal”), for a period of three (3) months thereafter (the “ROFR Negotiation Period”); provided that the ROFR Negotiation Period shall be extended for any period during which Five Prime has not complied with Section 3.6 above. For clarity, if the original notice is not for a worldwide license, then BMS’s rights shall remain in effect during the ROFR Offer Period with respect to the territory not covered by the original notice if Five Prime subsequently determines to expand the territory of the license. During the ROFR Negotiation Period, if requested by BMS, Five Prime will disclose to BMS all material information and results relating to the Five Prime CSF1R Program as promptly as practicable after such information and results become available. Any such information and results shall be treated as Confidential Information of Five Prime hereunder. If BMS and Five Prime do not reach an agreement for such rights within the ROFR Negotiation Period, then Five Prime will be free to out-license any and all rights (subject to the terms of this Agreement) to the Five Prime CSF1R Program in such territory; provided, however, that Five Prime shall not out-license the right to commercialize the Five Prime CSF1R Program in such territory (including any modification to such territory than was previously considered by BMS) to a Third Party within the ninety (90) day period after the end of the ROFR Offer Period without first offering to BMS the same terms that such Third Party offered to Five Prime (with such terms being memorialized in a written term sheet or proposed definitive agreement) (such terms, “Third Party Terms”) and allowing BMS ten (10) Business Days to accept such Third Party Terms (the end of such ten (10) Business Day period, the “Final Match Date”). In the event that Five Prime does not enter into a transaction with a Third Party with respect to the rights that are the subject of such Right of First Refusal within a period of *** subsequent to the Final Match Date or Five Prime does not receive (or make) an offer to any such Third Party that would give rise to the existence of any Third Party Terms and the ROFR Offer Period has not ended, then BMS rights under this Section 3.7 shall be reinstated for the remainder of the ROFR Offer Period, such that in the event that Five Prime determines that it wishes to out-license the right to commercialize the Five Prime CSF1R Program in any territory prior to the end of the ROFR Offer Period, Five Prime will again promptly notify BMS in writing of same and the territory as to which the license will cover, and BMS’s Right of First Refusal will once again apply on the same terms and conditions described above.

EXECUTION VERSION

3.8Right of First Negotiation. During the Term and subsequent to the ROFR Offer Period, if Five Prime determines that it wishes to out-license the right to commercialize the Five Prime CSF1R Program in any territory, Five Prime will inform BMS in writing of same and the territory as to which the license will cover. BMS will have an exclusive right to negotiate, for a period of three (3) months thereafter, to obtain exclusive rights to develop and commercialize the Five Prime CSF1R Program for such territory (the “ROFN Negotiation Period”). During the ROFN Negotiation Period, if requested by BMS, Five Prime will disclose to BMS all material information and results relating to the Five Prime CSF1R Program as promptly as practicable after such information and results become available. Any such information and results shall be treated as Confidential Information of Five Prime hereunder. Notwithstanding the foregoing, the ROFN Negotiation Period shall be extended for any period during which Five Prime has not complied with its obligations in the preceding sentence. If the original notice is not for a worldwide license, then BMS’s rights shall remain in effect with respect to the territory not covered by the original notice if Five Prime subsequently determines to expand the territory of the license. If BMS does not exercise its right of first negotiation for such rights to the Five Prime CSF1R Program or if an agreement is not reached between BMS and Five Prime for such rights within the ROFN Negotiation Period, then Five Prime will be free to out-license any and all rights (subject to the terms of this Agreement) to the Five Prime CSF1R Program for such territory.

5.3Other Clinical Trials. Except for the Combined Therapy Trials, each clinical trial for the BMS Compound and the Five Prime Compound, alone or in combination with other pharmaceutical agents, is independently conducted and shall not be subject to this Agreement (but without limiting each Party’s obligation to share relevant safety information as provided in Section 2.1(c), Section 2.1(d) and Section 2.2 and to comply with its obligations with respect to any Subsequent Studies). BMS Compound provided to Five Prime under this Agreement shall not be used for such other clinical trials. Except as provided in Section 3.5, nothing in this Agreement shall preclude either Party from conducting any such other clinical trials as it may determine in its discretion, so long as it does not use or rely on the Confidential Information of the other Party in doing so.

5.4Additional Studies. After completion of a Combined Therapy Trial in a Developed Tumor Type, the Parties agree to discuss in good faith additional clinical trials (other than clinical trials contemplated by Section 2.1(a)) of the Combined Therapy in such Developed Tumor Type for a period of up to *** after such Developed Tumor Type ceases being a Restricted Tumor Type. If the Parties jointly agree to conduct any such further clinical trials of such Combined Therapy in such Developed Tumor Type, such further clinical trials will be conducted in accordance with a separate agreement between the Parties and a revised Pharmacovigilance Agreement between the Parties (such revised Pharmacovigilance Agreement to be executed *** after the execution of the separate agreement but in any case before the initiation of any further clinical trials). For clarity, no Party shall be obligated to collaborate with the other Party or agree on terms with the other Party with respect to such additional clinical trials, except as follows:

(a)The provisions as set forth below shall only be in effect (and the Parties will only have the rights set forth below) with respect to each Subsequent Study in an indication that was a Developed Tumor Type for which the proposed protocol synopsis has been submitted by the Proposing Party to the Other Party (as set forth below) by the earlier of (i) *** after such indication ceased being a Restricted Tumor Type and (ii) the date that the Compounds of both parties have been approved in the U.S. and are commercially available for purchase (such earlier date, the “Subsequent Study Request Deadline”); provided that the proposed Subsequent Study must be commenced (first patient first visit) within *** of such protocol synopsis being provided to the Other Party; provided further that, in the event of termination of this Agreement, the provisions as set forth below shall only be in effect for a Proposing Party (and the Proposing Party will only have the rights set forth below) to the extent that Section 12.5 provides that the Proposing Party’s license to conduct Subsequent Studies under Section 3.1 or Section 3.2 (as applicable) survives such termination of this Agreement.

EXECUTION VERSION

(b)If one Party (for purposes of this Section 5.4 only, the “Proposing Party”) would like to conduct one or more clinical or required non-clinical studies of the use of the Combined Therapy in a Developed Tumor Type (each study being a “Subsequent Study”), the Proposing Party shall provide the other Party (for purposes of this Section 5.4 only, the “Other Party”) with a proposed protocol synopsis for such proposed Subsequent Study and the opportunity to participate in such Subsequent Study by the Subsequent Study Request Deadline. The Other Party shall have the right, which must be exercised (if at all) within *** after receipt of the protocol synopsis, to co-participate in and co-fund the proposed Subsequent Study under the same terms and conditions as the Agreement and, upon the election of the Other Party, the Parties shall enter into an agreement for the conduct of such Subsequent Study having substantially the same terms and conditions as this Agreement (the “Subsequent Study Agreement”), with the protocol (and any changes thereto) for the Subsequent Study to be subject to agreement of both parties and with the Proposing Party to be the sponsor of and primarily be responsible for conducting the Subsequent Study (i.e., as Five Prime is doing for the Combined Therapy Trials under the Development Plan). Any such Subsequent Study that the Parties co-participate in and co-fund is referred to in this Agreement as a “Joint Subsequent Study.”

(c)In the case the Other Party has declined to participate, but where material changes are made to the protocol for a proposed Subsequent Study (relative to the protocol synopsis that was most recently reviewed by the Other Party) before it is initiated, such protocol and Subsequent Study shall then be subject to a new review by the Other Party as a new proposal for a Subsequent Study (with the Other Party having the right to co-participate and co-fund set forth above, and otherwise review as set forth below).

(d)In the case where the Other Party does not desire to co-participate and co-fund the proposed Subsequent Study under a Subsequent Study Agreement or, if the Other Party elected to participate but both Parties otherwise do not reach agreement with respect to the Protocol or Subsequent Study Agreement within *** following the Other Party’s decision to participate in the proposed Subsequent Study (but no later than *** from the receipt by the Other Party of the proposed protocol synopsis (as amended pursuant to clause (c) above, if applicable) for the proposed Subsequent Study), the Proposing Party may proceed with the Subsequent Study, subject to the following conditions:

(i)such Subsequent Study is approved by all applicable IRBs, and is otherwise conducted in compliance with all Applicable Law;

(ii)the Subsequent Study shall not proceed if the Other Party has a reasonable significant safety objection to the conduct of the Subsequent Study (unless and until such safety objection is addressed to the Other Party’s reasonable satisfaction);

Page 46 of 84

EXECUTION VERSION

(iii)unless the Parties agree otherwise in writing, the dosage and dosage regimen of the Other Party’s Compound to be used in the Subsequent Study shall be within (A) the dosage and regimen in the approved label for such Compound (if such Compound is approved), (B) the protocol-determined expansion dosage and regimen for such Compound in any Phase 1b Combined Therapy Trial, (C) the final recommended Phase 2 dosage and regimen used for such Compound in any Phase 2 Combined Therapy Trial, (D) the dosage and regimen then being used for such Compound in any on-going Phase 2 or Phase 3 clinical study then being conducted by the Other Party for its Compound or (E) such other dose and regimen that the Parties agree on;

(iv)for the Subsequent Studies where Five Prime is the non-participating Other Party, the total number of subjects to be treated with Five Prime Compound in aggregate in all such Subsequent Studies shall not exceed *** (such that the total amount of Five Prime Compound to be manufactured by Five Prime for all such Subsequent Studies where Five Prime is the Other Party shall not exceed the amount required for the treatment of ***). BMS shall reimburse Five Prime for *** (without profit xxxx-up and determined in accordance with Five Prime’s customary practices in accordance with GAAP), ***;

(v)for the Subsequent Studies where BMS is the non-participating Other Party, the total number of subjects to be treated with BMS Compound in aggregate in all of such Subsequent Studies shall not exceed *** (such that the total amount of BMS Compound to be manufactured by BMS for all such Subsequent Studies where BMS is the Other Party shall not exceed the amount required for the treatment of ***). BMS shall supply the amount required for such Subsequent Studies ***;

(vi)the Proposing Party hereby grants to the Other Party a non-exclusive, worldwide, non-transferable, royalty-free license (with the right to sublicense solely pursuant to the terms of Section 3.3) to use any intellectual property generated as a result of a Subsequent Study solely to the extent such intellectual property relates to such non-participating Other Party’s Compound;

(vii)the Parties will enter into a mutually acceptable written Supply Agreement for the supply of the Other Party’s Compound (giving the Subsequent Study the same supply priority as the Other Party’s other clinical studies for the Compound), as well as a mutually acceptable quality agreement (in each case, the Parties to act in good faith and reasonably in finalizing such Supply and Quality Agreements);

(viii)Exhibit D sets forth a list of possible countries in which the Subsequent Studies may be conducted, provided that a Party shall not be obligated to supply its Compound for use in a country listed on Exhibit D or otherwise if such Party’s Compound has not previously been made available for clinical or commercial use in such country;

Page 47 of 84

EXECUTION VERSION

(ix)the Proposing Party shall indemnify, defend and hold harmless the Other Party against all third claims and any resulting liabilities, losses, damages, cost and expenses incurred by the Other Party arising out of such Third Party claims based on the use of the Other Party’s Compound in such Subsequent Study, except to the extent attributable to (i) the Other Party’s Compound not meeting applicable specifications or (ii) the negligence or willful misconduct of the Other Party (with the indemnification procedures to follow those set forth in Section 11.3); and

(x)the Other Party hereby grants a non-exclusive, fully-paid (with the Other Party to be responsible for any Third Party Payments as may be owed in connection therewith relating to the use of the Other Party’s Compound) license under the intellectual property controlled by it and its Affiliates to enable the Proposing Party to conduct the Subsequent Study.

Page 48 of 84

EXECUTION VERSION

(e)Subject to the above, the Other Party would provide the Proposing Party under the Supply Agreement with sufficient quantities of its Compound (subject to any forecasting, minimum order quantity, and similar provisions to be set forth in the Supply Agreement) to conduct the applicable Subsequent Study and promptly provide written authorization to the FDA and other applicable regulatory authorities of the Proposing Party’s Right to Cross-Reference the appropriate INDs (including any Combined Therapy Trial IND) and other Regulatory Documentation of the Other Party for its Single Agent Compound as may be required for the conduct of the Subsequent Study (subject to Applicable Law). Subject to Section 5.4(f), the same rights and obligations as set forth in the Agreement would apply with respect to each Subsequent Study with respect to the use and disclosure of results, sharing of information, safety data exchange and patent rights in connection with the applicable Subsequent Study (with such rights and obligations to be confirmed/restated in the Supply Agreement for such Subsequent Study). Accordingly, under the Supply Agreement for each Subsequent Study (but subject to Section 5.4(f)): (i) the Proposing Party will keep the Other Party informed of the progress of the Subsequent Study; (ii) the Other Party shall be entitled to use the Combination Therapy Data from the Subsequent Study to (1) submit regulatory filings and, subject to Section 5.4(f), seek approvals for its own Compound, either alone or as part of a combination use therapy with the Proposing Party’s Compound and (2) following the applicable approval, to promote indications based on, and to disseminate, the Combination Therapy Data for the benefit of its own Compound, either alone or as part of the combination therapy with the Proposing Party’s Compound, where permitted by and in accordance with Applicable Law and (iii) in the case where a Party submits Combination Therapy Data for regulatory approval for the use of its Single Agent Compound in combination with the other Party’s Single Agent Compound (including any reference to the Combination Therapy Data in its label), then the Party seeking approval shall be granted by the other Party a Right of Cross-Reference to the Other Party’s Regulatory Documentation (including any INDs owned or controlled by it for any Combined Therapy Trials) solely to the extent required for such purpose.

Page 49 of 84

EXECUTION VERSION

(f)In the case where the non-participating Other Party for a Subsequent Study elects to use the Combination Therapy Data from such Subsequent Study in a regulatory filing in the FDA or EMA for its Compound for purposes of obtaining approval of an indication for the Combination Therapy for its Compound, and the non-participating Other Party obtains such regulatory approval for such Combination Therapy indication (i.e., such approved Combination Therapy indication is included in the label for its Compound allowing promotion of such indication), then the Other Party shall thereafter be obligated to pay to the Proposing Party an amount in aggregate equal to *** of the documented out-of-pocket payments (other than costs of drug supply) to clinical trial sites, CROs and other contractors reasonably incurred by the Proposing Party directly as a result of the conduct of the applicable Subsequent Studies in such indication relied upon for the approval of the new indication (including costs for project management, document management, monitoring and site management, specimen management, laboratory, imaging, investigator grants, site costs, Compound labeling and storage, EDC, IVRS, consultants, contractors for the testing and screening of patients and lab costs) (for purposes of this Section 5.4(f) only, such aggregate amount, the “Cost Sharing Payment”). The Other Party shall pay the Proposing Party *** of the Cost Sharing Payment each year (without interest) (for purposes of this Section 3.4(b)(v) only, each such payment, a “Cost Sharing Installment”), such that the Cost Sharing Payment would be fully paid after *** Cost Sharing Installment payments, with the first payment to be made within *** after the date Regulatory Approval is obtained by the Other Party for such Combination Therapy indication and the next *** Cost Sharing Installments to be made within *** after each of the next *** of such Regulatory Approval. For clarity, use of the Combination Therapy Data by the Other Party in a regulatory filing for safety reporting purposes (or other purposes that do not permit the promotion of its Compound for the Combination Therapy indication) shall not trigger any Cost Sharing Payment.

(b)Defense. If both Parties are charged with infringement pursuant to a claim described in Section 6.4(a), the Parties shall defend such claim jointly, unless they agree otherwise. If only one Party is charged with infringement, such Party will have the first right but not the obligation to defend such claim. If the charged Party does not commence actions to defend such claim within *** after being so charged, then the other Party shall have the right, but not the obligation, to defend any such claim. In any event, the non-defending Party shall reasonably cooperate with the Party conducting the defense of the claim and shall have the right to participate with separate counsel at its own expense, and the defending Party shall consider comments by the non-defending Party in good faith. The Party defending the claim shall bear the cost and expenses of the defense of any such Third Party infringement claim and shall have sole rights to any recovery. If the Parties jointly defend the claim, Five Prime shall bear ***, and BMS shall bear *** of any costs and expenses of the defense of any such Third Party infringement claim; provided, however, that, notwithstanding the foregoing, if the claim relates solely to one Party’s Compound, such Party will bear *** of the costs and expenses of the defense of such claim and shall have the sole right, but not the obligation, to defend, settle and otherwise handle the disposition of such claim. Neither Party shall enter into any settlement concerning activities under this Agreement or the Combined Therapy that affects the other Party’s rights under this Agreement or imposes any obligations on the other Party, including any admissions of wrongdoing on behalf of the other Party, without such other Party’s prior written consent, not to be unreasonably withheld or delayed, except that a Party may settle any claim that solely relates to its Compound without the consent of the other Party as long as such other Party’s rights under this Agreement are not adversely impacted (in which case, it will obtain such other Party’s prior written consent, not to be unreasonably withheld or delayed).

7.3Invoicing; Payment.

(a)Reconciliation. Five Prime shall provide a report to BMS within *** after the end of each Quarter which shall set forth in reasonable detail all Third Party Study Costs and Section 4.2(b) Costs actually incurred during such Quarter by Five Prime (a “Quarterly Report”). If requested by BMS, Five Prime shall provide invoices or other appropriate supporting documentation for any payments to a Third Party exceeding ***. The Parties shall seek to resolve any questions related to such Quarterly Reports within *** following receipt by BMS of such Quarterly Report. Based on these Quarterly Reports, the Parties finance teams will determine the amount, if any, owed by BMS for such Quarter and such payment will be made by BMS within *** after the end of such *** reconciliation period.

(b)Budget Overruns. Any costs that are incurred by Five Prime that are *** greater than the JDC-approved budget shall require approval of the JDC for payment. If the reason for the costs exceeding such JDC-approved budget by more than *** is attributable to a Party’s negligence or breach of its obligations under this Agreement, then the costs incurred that are more than *** greater than the JDC-approved budget shall be the sole responsibility of such Party.

(c)Payment Method. BMS shall pay all amounts due hereunder in United States dollars to the bank account Five Prime designates in writing from time to time.

7.4Customs Valuation. Five Prime will provide BMS in writing with a list of all countries participating in a Combined Therapy Trial prior to study start initiation of such Combined Therapy Trial. During the conduct of such Combined Therapy Trial, Five Prime will send in writing any changes to the list of participating countries to BMS one month prior to the end of each Quarter. If no changes are sent to BMS by Five Prime for a particular Quarter, the prior Quarter’s participating country list will be used as the basis for customs valuation for that Quarter. BMS will provide Five Prime with Nivolumab country-specific customs valuations initially prior to study start initiation of Combined Therapy Trial(s) and at the end of each Quarter during the conduct of the Combined Therapy Trial. Five Prime will use the BMS provided values for the import/export process to the listed participating countries and not make any change to such valuations without BMS’s prior written consent.

EXECUTION VERSION

(b)Five Prime and BMS agree to collaborate to disclose publicly, publish or present (1) top-line results from the performance of the Development Plan, limited if possible to avoid jeopardizing the future publication of the Study Data at a scientific conference or in a scientific journal, solely for the purpose of disclosing, as soon as reasonably practicable, the safety or efficacy results and conclusions that are material to either Party under applicable securities laws, and (2) the conclusions and outcomes (the “Results”) of each Combined Therapy Trial at a scientific conference as soon as reasonably practicable following the completion of such Combined Therapy Trial, subject in the case of (2) to the following terms and conditions. The Party proposing to disclose, publish or present the Results shall deliver to the other Party a copy of (i) any abstract or press release at least *** before submission to a Third Party and (ii) any proposed slide presentation, publication, poster presentation or any other disclosure, publication or presentation at least *** before submission to a Third Party. The reviewing Party shall determine whether any of its Confidential Information that may be contained in such disclosure, publication or presentation should be modified or deleted, whether to file a patent application on any Five Prime Study Invention (solely with respect to Five Prime) or BMS Study Invention (solely with respect to BMS) or Combined Therapy Invention disclosed therein. The disclosure, publication or presentation shall be delayed for an additional *** (i.e., a total of *** from the initial proposal) if the reviewing Party reasonably requests such extension to allow time for the preparation and filing of relevant patent applications. If the reviewing Party reasonably requests modifications to the disclosure, publication or presentation to prevent the disclosure of a material trade secret or proprietary business information, the publishing Party shall edit such publication to prevent the disclosure of such information prior to submission of the disclosure, publication or presentation. In the event of a disagreement as to content, timing and/or venue or forum for any disclosure, publication or presentation of the Results, such dispute (a “Publication Dispute”) shall be referred to the Executive Officers (or their respective designees); provided that, in the absence of agreement after such good faith discussions, and upon expiration of the additional ***-period, academic collaborators engaged by Five Prime in connection with the performance of the Combined Therapy Trials may publish Combined Therapy Study Data obtained by such academic collaborator solely to the extent that such ability to publish such Combined Therapy Study Data is set forth in an agreement between Five Prime and such academic collaborator relating to the conduct of Combined Therapy Trials. Authorship of any publication shall be determined based on the accepted standards used in peer-reviewed academic journals at the time of the proposed disclosure, publication or presentation. The Parties agree that they shall make reasonable efforts to prevent publication of a press release that could jeopardize the future publication of Study Data at a scientific conference or in a scientific journal but in no way will this or any other provision of this Agreement supersede the requirements of any Applicable Law or the rules or regulations of any securities exchange or listing entity on which a Party’s stock is listed (including any such rule or regulation that may require a Party to make public disclosures about interim results of a Combined Therapy Trial). Notwithstanding the foregoing, Five Prime hereby authorizes disclosure to Ono in accordance with Section 9.4. Notwithstanding the foregoing, nothing herein shall prevent or restrict Ono from making any disclosures of published Study Data disclosed to it by BMS pursuant to Section 9.4 or of the existence of this Agreement, in each case in order for Ono to comply with requirements of

Applicable Law, the rules or regulations of any securities exchange or listing entity on which its stock may be traded or pursuant to an order of a court or governmental entity to publicly disclose the existence of the Agreement and the Study Data.

9.6Compliance with Sunshine Laws.

(a)For purposes of compliance with reporting obligations under Sunshine Laws, Five Prime represents that it is not, as of the Effective Date, subject to reporting obligations under the Sunshine Laws. Therefore, as between the Parties, BMS will report payments or other transfers of value (“POTV”) made by Five Prime or the CRO related to the conduct of the Combined Therapy Trials and any applicable associated contractor engagements as required under the Sunshine Laws, for each Combined Therapy Trial initiated prior to such date that Five Prime becomes responsible for reporting POTV for studies sponsored by it. BMS shall request delayed publication for any reported POTV for the studies sponsored by Five Prime as permitted under the Sunshine Laws and if consistent with BMS’s normal business practices. In the event Five Prime becomes responsible for reporting POTV for studies sponsored by it in a given country during the Term, Five Prime shall provide written notification to BMS, and the Parties will meet and confer to discuss how they wish to handle reporting thereafter. Interpretation of the Sunshine Laws for purposes of reporting any POTV by a Party shall be in such Party’s sole discretion so long as the interpretation complies with Applicable Law.

(b)Five Prime (i) will provide (to the extent in the possession of Five Prime), or will utilize Commercially Reasonable Efforts to obligate and ensure that each CRO and other applicable Third Party contractors for a Combined Therapy Trial provide, BMS with any information requested by BMS as BMS may reasonably determine is necessary for BMS to comply with its reporting obligations under Sunshine Laws (with such amounts paid to, or at the direction of, each Recipient to be reported to BMS within a reasonable time period specified by BMS) and (ii) will reasonably cooperate with, and will utilize Commercially Reasonable Efforts to obligate and ensure that each CRO and other applicable Third Party contractors for a Combined Therapy Trial reasonably cooperate with, BMS in connection with its compliance with such Sunshine Laws. The form in which Five Prime provides any such information shall be mutually agreed but sufficient to enable BMS to comply with its reporting obligations and BMS may disclose any information that it believes is necessary to comply with Sunshine Laws. BMS shall have the right to allocate payments or other transfers of value in connection with this Agreement in any required reporting under Sunshine Laws in accordance with its normal business practices. These obligations shall survive the expiration and termination of the agreement to the extent necessary for BMS to comply with Sunshine Laws.

(c)For purposes of this Section 9.7, “Sunshine Laws” means Applicable Laws requiring collection, reporting and disclosure of POTVs to certain healthcare providers, entities and individuals. These Applicable Laws may include relevant provisions of the Patient Protection and Affordable Health Care Act of 2010 and implementing regulations thereunder. “Recipients” means healthcare providers, teaching hospitals and/or any other Persons for whom transfers of value or payments must be reported under Sunshine Laws.

Five Prime hereby agrees to Indemnify BMS, its Affiliates, and its and their agents, directors, officers, and employees (the “BMS Indemnitees”) from and against any and all Losses resulting from Third Party Claims to the extent that they arise or result from (a) the negligence or intentional misconduct of Five Prime or any Five Prime Indemnitee or any (sub)licensee of Five Prime conducting activities on behalf of Five Prime under this Agreement; (b) any breach by Five Prime of any provision of this Agreement; (c) any injury to a subject in a Combined Therapy Trial or Joint Subsequent Study (but not any other Subsequent Study) to the extent caused by the development, use or manufacture of the Five Prime Compound; (d) any injury to a subject in a Combined Therapy Trial or Joint Subsequent Study (but not any other Subsequent Study) where it ultimately cannot be or is not determined if such injury is the direct result of the Five Prime Compound on the one hand or the BMS Compound on the other hand; provided that, in the case of this clause (d), Five Prime shall only Indemnify the BMS Indemnitees for *** of any such Loss; or (e) the use by Five Prime, its Affiliates, contractors or (sub)licensees of Combined Therapy Study Data, Five Prime Study Data, Five Prime Study Inventions, Five Prime Study Patent Rights, Combined Therapy Inventions and Combined Therapy Patent Rights outside the scope of this Agreement (other than with respect to Third Party Claims that are covered under Section 6.4)), including in the conduct of a Parallel Study or Subsequent Study other than a Joint Subsequent Study) by Five Prime, but excluding, in each case ((a) through (e)), any such Losses to the extent BMS is obligated to Indemnify the Five Prime Indemnitees pursuant to Section 11.1 or to the extent that the Third Party Claim is attributable to a failure of the BMS Compound used by Five Prime in a Parallel Study or Subsequent Study to have been manufactured in accordance with applicable specifications.

11.3Indemnification Procedure. Each Party’s agreement to Indemnify the other Party is conditioned on the performance of the following by the Party seeking indemnification: (a) providing written notice to the Indemnifying Party of any Loss of the types set forth in Section 11.1 and 11.2 within *** after the Party seeking indemnification has knowledge of such Loss; provided that any delay in complying with the requirements of this clause (a) will only limit the Indemnifying Party’s obligation to the extent of the prejudice caused to the Indemnifying Party by such delay; (b) permitting the Indemnifying Party to assume full responsibility to investigate, prepare for and defend against any such Loss; (c) providing reasonable assistance to the Indemnifying Party, at the Indemnifying Party’s expense, in the investigation of, preparation for and defense of any Loss; and (d) not compromising or settling such Loss without the Indemnifying Party’s written consent, such consent not to be unreasonably withheld or delayed.

11.4Separate Defense of Claims. In the event that the Parties cannot agree as to the application of Sections 11.1, 11.2 and/or 11.3 to any particular Loss, the Parties may conduct separate defenses of such Loss. Each Party further reserves the right to claim indemnity from the other in accordance with Sections 11.1, 11.2 and/or 11.3 upon resolution of the underlying claim, notwithstanding the provisions of Section 11.3(b).

TERM AND TERMINATION

12.1Term. This Agreement shall be effective as of the Effective Date and, unless earlier terminated pursuant to Sections 12.2, 12.3 or 12.4 or any other termination right expressly stated in this Agreement, shall continue in effect until the date which is ninety (90) days subsequent to completion by all centers or institutions participating in the Combined Therapy Trials, the delivery of all Study Data, including all completed case report forms, all final analyses and all final clinical study reports contemplated by the Combined Therapy Trials, to both Parties, and the completion of the Development Plan and any then-agreed upon Statistical Analysis and Bioanalysis Plan (the “Term”).

12.2Termination for Material Breach.

(a)Notice and Cure Period. If a Party (the “Breaching Party”) is in material breach, the other Party (the “Non-Breaching Party”) shall have the right to give the Breaching Party notice specifying the nature of such material breach. The Breaching Party shall have a period of *** after receipt of such notice to cure such material breach (the “Cure Period”) in a manner reasonably acceptable to the Non-Breaching Party. For the avoidance of doubt, this provision is not intended to restrict in any way either Party’s right to notify the other Party of any other breach or to demand the cure of any other breach.

(b)Termination Right. The Non-Breaching Party shall have the right to terminate this Agreement, upon written notice, in the event that the Breaching Party has not cured such material breach within the Cure Period, provided, however, that if such breach is capable of cure but cannot reasonably be cured within the Cure Period, and the Breaching Party notifies the non-Breaching Party of its intent to cure such material breach, commences actions to cure such material breach within the Cure Period and thereafter diligently continues such actions, the Breaching Party shall have an additional *** to cure such breach. If a Party contests such termination pursuant to the dispute resolution procedures under Section 13.3, such termination shall not be effective until a conclusion of the dispute resolution procedures in Section 13.3, as applicable, resulting in a determination that there has been a material breach that was not cured within the Cure Period (or, if earlier, abandonment of the dispute by such Party).

12.3Termination for Bankruptcy. Either Party may terminate this Agreement if, at any time, the other Party shall file in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of such other Party or of such other Party’s assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed or stayed within *** after the filing thereof, or if the other Party will propose or be a party to any dissolution or liquidation, or if the other Party shall make an assignment for the benefit of its creditors.

12.4Termination due to Material Safety Issue; Clinical Hold.

(a)Either Party shall have the right to terminate this Agreement immediately upon written notice if it reasonably deems it necessary to protect the safety, health or welfare of subjects enrolled in any Combined Therapy Trial due to the existence of a Material Safety Issue. In the event of a termination due to a Material Safety Issue, prior to the terminating Party providing written notice, each Party’s safety committee shall, to the extent practicable, meet and discuss in good faith the safety concerns raised by the terminating Party and consider in good faith the input, questions and advice of the non-terminating Party, but should any dispute arise in such discussion, the dispute resolution processes set forth in Sections 2.8 or 13.3 shall not apply to such dispute and the terminating Party shall have the right to issue such notice and such termination shall take effect without the Parties first following the procedures set forth in Sections 2.8 or 13.3.

(b)If a Clinical Hold with respect to either the BMS Compound or the Five Prime Compound should arise at any time after the Effective Date, the Parties will meet and discuss the basis for the Clinical Hold, how long the Clinical Hold is expected to last, and how they might address the issue that caused the clinical hold. If, after ninety (90) days of discussions following the Clinical Hold, either Party reasonably concludes that the issue is not solvable or that unacceptable and material additional costs/delays have been and/or will continue to be incurred in the conduct of the Combined Therapy Trial, then such Party may immediately terminate this Agreement.

Any such wind-down activities will include the return to BMS, or destruction, of all BMS Compound provided to Five Prime and not consumed in the performance of the Development Plan. If applicable, upon termination of this Agreement, the Parties shall remain responsible pursuant to the terms of this Agreement for any expenses incurred that are associated with terminating any ongoing clinical trial work and/or result from such ongoing activities under this Agreement solely to the extent such activities are deemed necessary by Five Prime (after discussion at a meeting of the JDC) based on reasonable medical judgment to protect the health of subjects participating in any Combined Therapy Trial.

PRESS RELEASE

Xxxxxxx-Xxxxx Squibb and Five Prime Therapeutics Announce Exclusive Clinical Collaboration to Evaluate the Combination of Investigational Immunotherapies Opdivo (nivolumab) and FPA008 in Six Tumor Types

(NEW YORK and SOUTH SAN FRANCISCO, CA – November 24, 2014) - Xxxxxxx-Xxxxx Squibb Company (NYSE:BMY) and Five Prime Therapeutics, Inc. (Nasdaq:FPRX) today announced that they have entered into an exclusive clinical collaboration agreement to evaluate the safety, tolerability and preliminary efficacy of combining Opdivo (nivolumab), Xxxxxxx-Xxxxx Squibb’s investigational PD-1 immune checkpoint inhibitor, with FPA008, Five Prime’s monoclonal antibody that inhibits colony stimulating factor-1 receptor (CSF1R). The Phase 1a/1b study will evaluate the combination of Opdivo and FPA008 as a potential treatment option for patients with non-small cell lung cancer (NSCLC), melanoma, head and neck cancer, pancreatic cancer, colorectal cancer and malignant glioma. Xxxxxxx-Xxxxx Squibb has proposed the name Opdivo, which, if approved by health authorities, will serve as the trademark for nivolumab.

Opdivo and FPA008 are part of a new class of cancer treatments known as immunotherapies that are designed to harness the body’s own immune system to fight cancer. Opdivo is approved in Japan for the treatment of patients with unresectable melanoma, and is being developed in multiple tumor types in more than 50 clinical trials. FPA008, in development as a potential treatment for rheumatoid arthritis (RA) and solid tumors, has initiated dosing for a Phase 1 clinical trial in RA. Preclinical data suggest that combining antibodies targeting PD-1 and CSF1R may lead to an enhanced anti-tumor immune response compared to either approach alone in treating cancer.

EXECUTION VERSION

“This collaboration supports our strategy to expand the clinical development of Opdivo, including novel combination regimens and across numerous tumor types,” said Xxxxxxx Xxxxxxxx, senior vice president, Head of Development, Oncology, Xxxxxxx-Xxxxx Squibb. “We are excited to build upon our existing relationship with Five Prime Therapeutics in immuno-oncology, and explore the full potential of Opdivo and FPA008 in multiple tumor types.”

“We are pleased to establish a second collaboration with Xxxxxxx-Xxxxx Squibb in the area of immuno-oncology,” said Xxxxx X. “Xxxxx” Xxxxxxxx, M.D., Ph.D., president and chief executive officer of Five Prime. “Their vision aligns with our commitment to advancing promising immune-modulating targets, alone or in combination, to create next-generation immunotherapies for cancer patients. We look forward to initiating this study and expanding the development of FPA008 as a potential immunotherapy for these six types of cancer.”

Under the terms of this agreement, Xxxxxxx-Xxxxx Squibb will make a one-time payment of $30 million to Five Prime and will be responsible for study costs. Five Prime will conduct the clinical trial, which is expected to begin in the second half of 2015. The agreement provides for exclusivity with respect to the development, with a collaborative partner, of combination regimens of an anti-PD-1/PD-L1 antagonist together with an anti-CSF1R antagonist. Xxxxxxx-Xxxxx Squibb will have a time-limited right of first refusal subject to certain conditions if Five Prime wishes to seek a partner for FPA008.

About Opdivo (nivolumab)

Cancer cells may exploit “regulatory” pathways, such as checkpoint pathways, to hide from the immune system and shield the tumor from immune attack. Opdivo is an investigational, fully-human PD-1 (programmed death-1) immune checkpoint inhibitor that binds to the checkpoint receptor PD-1 expressed on activated T-cells.

Xxxxxxx-Xxxxx Squibb has a broad, global development program to study Opdivo in multiple tumor types consisting of more than 50 trials – as monotherapy or in combination with other therapies – in which more than 7,000 patients have been enrolled worldwide. Among these are several potentially registrational trials in non-small cell lung cancer (NSCLC), melanoma, renal cell carcinoma (RCC), head and neck cancer, glioblastoma and NHL.

EXECUTION VERSION

In 2013, the FDA granted Fast Track designation for Opdivo in NSCLC, melanoma and RCC. In April 2014, the company initiated a rolling submission with the FDA for Opdivo in third-line pre-treated squamous cell NSCLC and expects to complete the submission by year-end. The FDA granted its first Breakthrough Therapy Designation for Opdivo in May 2014 for the treatment of patients with Hodgkin lymphoma after failure of autologous stem cell transplant and brentuximab. On July 4, Ono Pharmaceutical Co. announced that Opdivo received manufacturing and marketing approval in Japan for the treatment of patients with unresectable melanoma, making Opdivo the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. On September 26, Xxxxxxx-Xxxxx Squibb announced that the FDA accepted for priority review the Biologics License Application for previously treated advanced melanoma, and the Prescription Drug User Fee Act goal date for a decision is March 30, 2015. The FDA also granted Opdivo Breakthrough Therapy status for this indication. In the European Union, the European Medicines Agency (EMA) has validated for review the Marketing Authorization Application (MAA) for Opdivo in advanced melanoma. The application has also been granted accelerated assessment by the EMA’s Committee for Medicinal Products for Human Use. The EMA also validated for review the MAA for Opdivo in NSCLC.

About FPA008

FPA008, an antibody that inhibits colony stimulating factor-1 receptor (CSF1R), blocks the activation and survival of monocytes and macrophages. Inhibition of CSF1R in inflamed RA joints blocks the production of inflammatory cytokines by macrophages and inhibits osteoclasts, monocyte-lineage cells that can cause bone erosions and joint destruction. Inhibition of CSF1R in many cancers reduces the number of immunosuppressive tumor-associated macrophages (TAMs), thereby facilitating an immune response against tumors.
