2.1.1 General Description. As set forth in Section 3.1, Celgene has Options on Programs, each of which is focused on a Collaboration Target as described below.

(a) ICOS Activator Program and PD-1 Activator Program. As of the Effective Date, Jounce has developed JTX-2011 to treat cancer by targeting ICOS, and has developed JTX-4014 to treat cancer by targeting PD-1. Both ICOS and PD-1, each solely with respect to Collaboration Candidates that are Immune Activators, are Collaboration Targets and subjects of the ICOS Activator Program and the PD-1 Activator Program, respectively.

(b) Other Programs; Expansion of Pre-LO Target Pool. In addition, the Collaboration may include certain “Other Programs” that contain Biologics that are Specifically Directed to Available Targets and that are either Immune Activators or Immune Suppressors as follows (provided that, solely with respect to ICOS and PD-1, “Other Programs” shall only include Biologics that are Immune Suppressors):

(i) Macrophages. By screening Macrophages, Jounce has discovered certain Targets, listed on Exhibit F, that may be useful in treating diseases in the Field (such Targets listed on Exhibit F as of the Effective Date under the column “Available Macrophage Targets” the “Initial Macrophage Targets”). During the Research Term, as part of the Collaboration, Jounce may (a) perform various screens in accordance with Section 2.2.2(a) to identify, or (b) otherwise Develop alone or with Third Parties, for each of (a) and (b), additional potential Targets (other than Excluded Jounce Targets and Excluded Celgene Targets) expressed by Macrophages which, by binding of a Biologic (Developed by or on behalf of Jounce) to an applicable Target on such Macrophage or by binding of a Biologic (Developed by or on behalf of Jounce) that is a ligand trap that contains such Target or a fragment thereof, causes significant Immune Activation or Immune Suppression (together with the Initial Macrophage Targets, such Targets the “Available Macrophage Targets”)

(ii) B-Cell/Treg Targets. During the Research Term, as part of the Collaboration, Jounce may (a) perform various screens in accordance with Section 2.2.2(a) to identify, or (b) otherwise Develop alone or with Third Parties, for each of (a) and (b), additional potential Targets (other than Excluded Jounce Targets and Excluded Celgene Targets) expressed by B-Cell/Treg Targets which, by binding of a Biologic (Developed by or on behalf of Jounce) to an applicable Target on such B-Cell or Treg or by binding of a Biologic (Developed by or on behalf of Jounce) that is a ligand trap that contains such Target or a fragment thereof, causes significant Immune Activation or Immune Suppression (such Targets the “Available B-Cell/Treg Targets”).

(iii) Progression of Pre-LO Targets to Collaboration Targets. As further described and subject to the definition of “Pre-LO Target Pool” and Section 2.2.2(b), (A) the Available Macrophage Targets and the Available B-Cell/Treg Targets, (B) any additional Proposed Targets that are added by mutual written agreement of the Parties (which shall thereafter be deemed other “Available Targets”) and (C) ICOS and PD-1 (each solely with respect to Collaboration Candidates Specifically Directed to ICOS or PD-1, respectively, that are Immune Suppressors), will form the Pre-LO Target Pool. Each (x) Available Macrophage Target or Available B-Cell/Treg Target and/or (y) other Available Target (including ICOS or PD-1, each solely with respect to Collaboration Candidates Specifically Directed to ICOS or PD-

1, respectively, that are Immune Suppressors), that [***] shall be deemed to be moved from the Pre-LO Target Pool to the LO Target Pool in accordance with Section 2.2.2 and shall thereafter be deemed a “Collaboration Macrophage Target”, “Collaboration B-Cell/Treg Target”, or “Collaboration Other Target” (with respect to subpart (y) above), as applicable, and each such Collaboration Macrophage Target, Collaboration B-Cell/Treg Target or Collaboration Other Target and its corresponding Biologics that are Immune Activators or Immune Suppressors, as applicable, shall together be deemed “Other Programs” (subject to Section 2.1.6).

(c) Development. Jounce will provide updates on the progress of each Program at the JSC meetings, including providing a periodic Portfolio Roadmap in accordance with Section 2.2.4. If merited by the research results, Jounce may in its sole discretion pursue one or more Collaboration Candidates within a Program through [***], a “Development Candidate”).

2.1.2 ICOS Activator Program.

(a) Commencing on the Effective Date until expiration of the JTX-2011 Option Term, Jounce may, in its sole discretion, conduct the ICOS Activator Program (which may be in accordance with the JTX-2011 IDP when any such IDP is established) with the goal of advancing JTX-2011 through the Evaluation of POC.

(b) The Parties acknowledge that in the course of Jounce performing the research activities under this Agreement with respect to the B-Cell/Treg Targets, certain B-Cell/Treg Targets may be Bundled B-Cell/Treg Targets. In the event that Jounce develops a Collaboration Candidate Specifically Directed against a Bundled B-Cell/Treg Target (each such Collaboration Candidate a “Bundled B-Cell/Treg Collaboration Candidate”), and Jounce decides to advance such Bundled B-Cell/Treg Collaboration Candidate, Jounce may, in its sole discretion, conduct the B-Cell/Treg Program consisting of such Bundled B-Cell/Treg Target and such Bundled B-Cell/Treg Collaboration Candidate (each such B-Cell/Treg Program, a “Bundled B-Cell/Treg Program”) in accordance with Section 2.1.5(a).

(c) In the event that Jounce advances more than one (1) Bundled B-Cell/Treg Collaboration Candidate that is Specifically Directed to separate Bundled B-Cell/Treg Targets that are included in the same Bundled B-Cell/Treg Target Group, then: (x) each such Bundled B-Cell/Treg Collaboration Candidate shall be the subject of a separate Bundled B-Cell/Treg Program; (y) each such separate Bundled B-Cell/Treg Program described in (x) above shall be offered as an additional Option to Celgene in accordance with Section 3.1.6; and (z) the second and any subsequent Option exercised by Celgene with respect to the same Bundled Target Group shall not count towards Celgene’s maximum Option exercise Option Cap under Section 3.1.

2.1.6 Lead Program. As of the Effective Date, the first Development Candidate Specifically Directed against an Available Target (excluding ICOS and PD-1 solely with respect to Collaboration Candidates that are Immune Activators) for which an IND is filed and which Jounce elects to advance shall be deemed the “Lead Program” and such Collaboration Target shall be the “Lead Collaboration Target”. For the avoidance of doubt, at the time of designation of the Lead Program, the remaining Collaboration Targets shall thereafter continue to be “Collaboration Targets”.

2.1.7 Lead Program Substitution. In the event that Jounce delivers the Lead Program Data Package to Celgene, Celgene may (i) exercise its Lead Program Option for such Lead Program and enter into a Celgene Lead Co-Development and Co-Commercialization Agreement, (ii) notify Jounce that it declines to exercise its Lead Program Option for such Lead Program, and upon delivery of such notification Celgene’s Lead Program Option shall expire, or (iii) substitute the “Lead Program” that is described in such Lead Program Data Package for a different Other Program in accordance with and under the following conditions described in this Section 2.1.7 (any such substitution, the “Lead Program Substitution”). Notwithstanding anything to the contrary in this Agreement, Celgene shall only be permitted to exercise its Lead Program Substitution right once during the Research Term.

(a) If, at the time of delivery of such Lead Program Data Package, Celgene has not exercised any Other Program Option, then Celgene may, instead of exercising its Lead Program Option under Section 3.1.3 for the Program described in such Lead Program Data Package, in its Option Exercise Notice: (A) elect to designate the Lead Program described in such Lead Program Data Package (the “Former Lead Program”) as the First Other Program (at which time such Former Lead Program shall thereafter be deemed the “First Other Program” for purposes of Celgene’s Option Cap and for entry into the applicable Jounce Lead Co-Development and Co-Commercialization Agreement with related economics as further described in Section 6.4.4) and elect to enter into a Jounce Lead Co-Development and Co-Commercialization Agreement for the Former Lead Program as the First Other Program in accordance with Section 3.1.7, provided that if Celgene does not elect to designate the Former Lead Program as the First Other Program in such Option Exercise Notice as described herein, then the Lead Program Option shall automatically expire; and (B) designate a replacement Collaboration Target from the Other Programs in existence as of the date of delivery of such Option Exercise Notice to advance as the Lead Collaboration Target. After the occurrence of the Lead Program Substitution in accordance with this Section 2.1.7(a), Jounce may in its sole discretion advance such replacement Lead Collaboration Target as the Lead Program in accordance with this Agreement, including Section 4.2.5, up to obtaining an IND Approval[***] and, if Celgene delivers a timely Option Exercise Notice for such replacement Lead Program, Celgene shall be deemed to have exercised its Lead Program Option with respect to such replacement Lead Program, the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization Agreement for such replacement Lead Program and Celgene shall pay the amount set forth in Section 6.4.2. Notwithstanding the foregoing, Celgene may postpone exercise of its Lead Program Option with respect to such replacement Lead Program until delivery of an [***] (and for the corresponding period ending on the Data Package Verification Date) for such replacement Lead Program. Notwithstanding anything to the contrary in this Agreement, Celgene shall only be permitted to exercise the Lead Program Substitution described in this Section 2.1.7(a) one (1) time.

(b) If at the time of delivery of such Lead Program Data Package, Celgene has exercised its Other Program Option for only one (1) Other Program (such Other Program for which Celgene has exercised its first Other Program Option, the “First Other Program”): (A) Celgene may in its Option Exercise Notice, instead of exercising its Lead Program Option for the Former Lead Program, elect to substitute the Former Lead Program for the First Other Program (at which time, the Former Lead Program shall no longer be the “Lead Program” and shall thereafter be deemed the “First Other Program” under and subject to the then-existing Jounce Lead Co-Development and Co-Commercialization Agreement (and related economics as further described in Section 6.4)) and the Other Program that was the subject of the then-existing Jounce Lead Co-Development and Co-Commercialization Agreement shall thereafter be deemed the “Lead Program” and the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization Agreement (with related Lead Program economics which, for purposes of payment of the Option exercise payments set forth in Section 6.4, shall only include payment of the amount set forth in Section 6.4.2 and not 6.4.4) for such Other Program, and the Parties shall (x) take such actions as are necessary to transition the First Other Program from Jounce-led Development to Celgene-led Development, including transferring regulatory filings, Patent prosecution and other activities, and (y) within [***] after entering into the applicable Celgene Lead Co-Development and Co-Commercialization Agreement, make such payments as are necessary to conform the allocation of all costs incurred for the First Other Program to comply with the provisions of the applicable Celgene Lead Co-Development and Co-Commercialization Agreement as if such First Other Program had been conducted under a Celgene Lead Co-Development and Co-Commercialization Agreement from the date that Celgene exercised its Other Program Option; or (B) in the event that Celgene does not make a Lead Program Substitution under this Section 2.1.7(b), Celgene shall not have the right to substitute the Lead Program with any Other Program under this Agreement under any other circumstances with respect to the conditions described in this Section 2.1.7(b). Upon the occurrence of the Lead Program Substitution in accordance with this Section 2.1.7(b): (i) Celgene shall be deemed to have exercised its Lead Program Option with respect to the Program that was the subject of the then-existing Jounce Lead Co-Development and Co-Commercialization Agreement (i.e. the former First Other Program); and (ii) Celgene shall be deemed to have exercised its Option for the First Other Program with respect to the Former Lead Program under Section 3.1.4. Notwithstanding anything to the contrary in this Agreement, Celgene shall only be permitted to exercise the Lead Program Substitution described in this Section 2.1.7(b) one (1) time.

(c) If at the time of delivery of such Lead Program Data Package, Celgene has exercised its Option for more than one (1) Other Program, Celgene may in its Option Exercise Notice, instead of exercising its Lead Program Option for the Former Lead Program, elect to substitute such Former Lead Program with either: (i) the First Other Program, at which time the Former Lead Program shall no longer be the “Lead Program” and shall thereafter be deemed the “First Other Program” under and subject to the then-existing Jounce Lead Co-Development and Co-Commercialization Agreement (and related economics as further described in Section 6.4) and the Other Program that was the subject of the then-existing Jounce Lead Co-Development and Co-Commercialization Agreement shall thereafter be deemed the “Lead Program” and the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization Agreement (with related Lead Program economics) for such Other Program, and the Parties shall (x) take such actions as are necessary to transition the First Other Program

from Jounce-led Development to Celgene-led Development, including transferring regulatory filings, Patent prosecution and other activities, and (y) within [***] after entering into the applicable Celgene Lead Co-Development and Co-Commercialization Agreement, make such payments as are necessary to conform the allocation of all costs incurred for the First Other Program to comply with the provisions of the applicable Celgene Lead Co-Development and Co-Commercialization Agreement as if such First Other Program had been conducted under a Celgene Lead Co-Development and Co-Commercialization Agreement from the date that Celgene exercised its Other Program Option; or (ii) any Other Program for which Celgene has exercised its Other Program Option that is not the First Other Program and is then the subject of a Celgene Lead Co-Development and Co-Commercialization Agreement (with applicable Other Program economics) (“Additional Other Program”), at which time, the Program described in such Lead Program Data Package shall no longer be the “Lead Program” and shall thereafter be deemed the “Additional Other Program” under and subject to the then-existing Celgene Lead Co-Development and Co-Commercialization Agreement and the Additional Other Program that was the subject of the then-existing Celgene Lead Co-Development and Co-Commercialization Agreement shall thereafter be deemed the “Lead Program” and the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization Agreement (with related Lead Program economics) for such Additional Other Program. In the event that Celgene does not make a Lead Program Substitution under Section 2.1.7(c)(i) or (ii), Celgene shall not be permitted to substitute the Lead Program with an Other Program under this Agreement under any other circumstances with respect to the conditions described in this Section 2.1.7(c). Upon the occurrence of the Lead Program Substitution in accordance with this Section 2.1.7(c): (A) Celgene shall be deemed to have exercised its Lead Program Option with respect to the First Other Program or the Additional Other Program, as applicable; and (B) Celgene shall be deemed to have exercised an Other Program Option with respect to the Program that is described in such Lead Program Data Package with the economics applicable to such Other Program chosen by to Celgene to substitute for the Lead Program as further described in Section 6.4.5 and Section 6.4.6, as applicable. Notwithstanding anything to the contrary in this Agreement, Celgene shall only be permitted to exercise the Lead Program Substitution described in this Section 2.1.7(c) one (1) time.

(d) Notwithstanding the foregoing, in the event that Jounce does not deliver the Lead Program Data Package to Celgene by the end of the Research Term and Celgene has exercised at least one (1) Other Program Option, then Celgene may, instead of exercising its Lead Program Option for the Lead Program in existence at the time of such expiration, either:

(i) select an Other Program for which Celgene has previously exercised its Other Program Option that is the subject of a Development & Commercialization Agreement to designate as the “Lead Program” and following such designation Celgene shall be deemed to have exercised its Lead Program Option and the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization Agreement for such Other Program as the “Lead Program” with the Lead Program economics as further described in Section 6.4 for such Other Program, and, if such Other Program is the First Other Program that is subject to Jounce Lead Co-Development and Co-Commercialization Agreement, then the Parties shall (x) take such actions as are necessary to transition the First Other Program from Jounce-led Development to Celgene-led Development, including transferring regulatory filings, Patent prosecution and other

activities, and (y) within [***] after entering into the applicable Celgene Lead Co-Development and Co-Commercialization Agreement, make such payments as are necessary to conform the allocation of all costs incurred for the First Other Program to comply with the provisions of the applicable Celgene Lead Co-Development and Co-Commercialization Agreement as if such First Other Program had been conducted under a Celgene Lead Co-Development and Co-Commercialization Agreement from the date that Celgene exercised its Other Program Option; or

(ii) exercise its Lead Program Option with respect any Other Program in existence prior to the expiration of the Research Term for which Celgene has not exercise its Other Program Option.

If Celgene, in its sole discretion and where applicable, agrees to perform the activities assigned to Celgene under the applicable IDP, then Celgene, at its sole cost and expense, shall use diligent efforts to perform such activities in accordance with such IDP.

2.2.2 Inclusion of Macrophage Targets and B-Cell/Treg Targets into the Collaboration.

(a) Screening for Available Macrophage Targets and Available B-Cell/Treg Targets. Within [***] after the Effective Date, Jounce, in its sole discretion, [***] Initial Macrophage Targets for the purpose of identifying Available Macrophage Targets and Available B-Cell/Treg Targets that may be added to the Pre-LO Target Pool. Jounce, in its sole discretion, [***] Initial Macrophage Targets [***].

(b) Process of Determining Pre-LO Target Pool. From time to time during the Research Term:

(i) Jounce, promptly after determining the Available Macrophage Targets and Available B-Cell/Treg Targets, including in accordance with Section 2.2.2(a), shall provide to Celgene a cumulative written list of all such Available Macrophage Targets and/or Available B-Cell/Treg Targets (such cumulative list, the “Proposed Pre-LO Target List”); it being understood and agreed that the Proposed Pre-LO Target List shall in all cases exclude any Excluded Jounce Targets.

(ii) Within [***] following receipt of each Proposed Pre-LO Target List, Celgene shall with respect to any Available Target thereon notify Jounce in writing of any Immune Activating Program or Immune Suppressing Program for such Available Target

[***] (“Excluded Celgene Program”) [***] “Excluded Celgene Target”. [***] Any Available Macrophage Targets, Available B-Cell/Treg Targets and/or other Available Targets on such Proposed Pre-LO Target List that are not excluded from the Collaboration by Celgene in writing in accordance with this Section 2.2.2(b)(ii) shall automatically be added to the Pre-LO Target Pool and shall be deemed “Pre-LO Targets”; provided, however, that Celgene may, at any time during the Research Term or the Option Term, exclude a Pre-LO Target from the Pre-LO Target Pool as an Excluded Celgene Target upon written notice to Jounce. Except for any Available Target that is an Excluded Jounce Target, Excluded Celgene Target or Lapsed Target, all of the Available Targets on the Proposed Pre-LO Target List shall be deemed to be included in the “Pre-LO Target Pool”. For clarity, the Initial Macrophage Targets, ICOS and PD-1 (with respect to to ICOS or PD-1, solely for Collaboration Candidates that are Immune Suppressors) shall be deemed to be included in the Pre-LO Target Pool as of the Effective Date.

(iii) With respect to any Excluded Celgene Program or Excluded Celgene Target: (A) all rights granted by Jounce to Celgene with respect to such Excluded Celgene Program or Excluded Celgene Target, as applicable, shall revert to Jounce in accordance with Section 2.2.2(f), (B) subject to ARTICLE 8, Celgene shall return to Jounce, or destroy, at Jounce’s option, all Confidential Information and/or Materials provided by Jounce to Celgene solely with respect to such Excluded Celgene Program or Excluded Celgene Target, as applicable; provided, however, that any Confidential Information and/or Materials that also relate to another Program may be retained and used by Celgene; (C) Celgene shall not have the right to exercise an Option with respect to any Excluded Celgene Program; (D) Jounce’s obligations under this Agreement shall no longer apply, including under Section 5.1; and (E) subject to (B) above, Celgene shall not have the right to use any Jounce Know-How or Jounce Confidential Information that relates to such Excluded Celgene Program or Excluded Celgene Target, as applicable for any purpose. Notwithstanding anything to the contrary contained herein, Celgene shall additionally be entitled to designate, in a written notice (“Limited Target Notice”) to Jounce, any Pre-LO Target for which Celgene wishes to receive specified or no additional information (and, for clarity, Celgene may include in such Limited Target Notice whether it wishes to receive such information with respect to solely Immune Activators or Immune Suppressors, or both) and/or to have a Third Party designee receive and review such information (any such designated Pre-LO Target, a “Limited Target”); it being understood and agreed that Celgene shall be entitled to modify (x) the designation of any Limited Target such that the corresponding Pre-LO Target is no longer a Limited Target, and (y) the information restrictions and recipients then-imposed with respect to such Limited Target. In each initial Limited Target Notice and in any subsequent modifications to such Limited Target Notice, Celgene shall include (A) the identity of the corresponding Limited Target, (B) a detailed written description of the limited information, if any, that Celgene wishes to receive for such Limited Target (such limited information the “Limited Information”), and (C) the identity and address of Celgene’s designee (if any) that Celgene wishes to receive the Limited Information.

(c) Advancement to LO Target Pool; LO Data Package. Jounce may, in its sole discretion, Develop any applicable Immune Activating Collaboration Candidate or Immune Suppressing Collaboration Candidate Specifically Directed to a Pre-LO Target with the goal of advancing each such Collaboration Candidate towards the LO Criteria set forth on Schedule 2.2.2. Based upon [***], either Jounce or Celgene may nominate the applicable Pre-LO Target to become an LO Target with respect to the applicable Program (i.e., such Pre-LO

Target and the applicable Immune Activating Collaboration Candidate(s) or Immune Suppressing Collaboration Candidate(s) that are Specifically Directed to such Pre-LO Target). For clarity, if both Immune Activating Collaboration Candidates and Immune Suppressing Collaboration Candidates are in existence with respect to such Pre-LO Target, such Immune Activating Collaboration Candidate(s) and Immune Suppressing Collaboration Candidate(s) shall be part of two (2) separate Programs hereunder and each such Program shall be assessed separately with respect [***], by providing written notification thereof to Celgene and the JSC. Within [***] following any such proposed nomination of a Pre-LO Target and the applicable Program(s), Jounce shall use its reasonable efforts to deliver to Celgene and the JSC an LO Data Package for such Pre-LO Target; provided that, for any such Program nominated by Celgene, Jounce shall include only as much data or information as is reasonably available at the time of Celgene’s request for such LO Data Package.

(d) LO Criteria. Following nomination of a Pre-LO Target as an LO Target and delivery of an LO Data Package by Jounce pursuant to Section 2.2.2(c), the [***]; provided that if [***] after the delivery of such Pre-LO Target’s LO Data Package, then: (i) either Party shall have the right to submit such matter to a panel of three Qualified Scientists (each and every such panel of three Qualified Scientists, a “Scientific Panel”) appointed as provided in this Section 2.2.2(d) for [***]; it being understood and agreed that, in connection with any review and determination by the Scientific Panel, the Scientific Panel [***]; and (ii) within [***] following any such submission to a Scientific Panel, each of Jounce and Celgene shall nominate a Qualified Scientist to participate on the applicable Scientific Panel and, if the Parties are unable to agree upon a third Qualified Scientist for such Scientific Panel within [***] following any such request for a Scientific Panel, then the initial two Qualified Scientists shall select such third Qualified Scientist within [***] after the expiration of such [***] period. For purposes of this Agreement, a “Qualified Scientist” shall mean any scientist (A) with at least [***] of pharmaceutical biologics and antibody development industry experience, (B) who has not worked for or been engaged by either Party in the [***] period immediately prior to the formation of the applicable Scientific Panel, and (C) who does not own equity in either Party. Each Scientific Panel shall act as follows: (I) each Qualified Scientist (and the Scientific Panel as a whole) shall act as an expert and not as an arbitrator; (II) each decision of the Scientific Panel shall be by majority vote of the three Qualified Scientists; (III) the decision of the Scientific Panel is, in the absence of fraud or manifest error, final and binding on the Parties; (IV) the costs of the Scientific Panel shall be shared equally by Jounce and Celgene; and (V) the Parties agree that only if such Scientific Panel determines that such Collaboration Candidate (which is an Immune Activator or Immune Suppressor, as applicable) for such Pre-LO Target [***] will such Pre-LO Target be presented to Celgene in accordance with Section 2.2.2(e) for a determination of whether such Pre-LO Target shall be added to the LO Target Pool and if such Scientific Panel determines that such Collaboration Candidate (which is an Immune Activator or Immune Suppressor, as applicable) for such Pre-LO Target [***] such Pre-LO Target shall not be presented to Celgene in accordance with Section 2.2.2(e); provided, however, that (x) if the applicable Collaboration Candidate is an Immune Suppressor of such Pre-LO Target and the Scientific Panel determines such Collaboration Candidate [***], then all Biologics which are Immune Activators of such Pre-LO Target (if any) shall remain in the Collaboration as separate Other Programs, or (y) if the applicable Collaboration Candidate is an Immune Activator of the Target, then all Biologics which are Immune Suppressors of such Pre-LO Target (if any) shall remain in the Collaboration as separate Other Programs. Conversely, if such Scientific Panel

determines that any such Collaboration Candidate for such Pre-LO Target [***], then such Pre-LO Target shall remain in the Pre-LO Target Pool and remain eligible for nomination to the LO Target Pool as a Collaboration Target during the Research Term.

Subject to this Section 3.1, with respect to each of the Other Programs, Jounce hereby grants to Celgene three (3) exclusive Options, exercisable at any time during the applicable Option Term, to enter into a Development & Commercialization Agreement with respect to such Other Programs (including the applicable Development Candidate and all Collaboration Candidates of such Other Program that are either Immune Activators or Immune Suppressors, as applicable, but not both Immune Activators and Immune Suppressors with respect to such Other Program’s Available Target, and applicable Program-Specific Reagents thereunder) and any related Diagnostic Products developed therefor, as set forth in and on the terms and conditions set forth in the Development & Commercialization Agreement (and each applicable Collaboration Candidate under such Other Program shall be deemed a “Co-Co Candidate” thereunder) (each such Option an “Other Program Option”).

3.1.5 Paired Programs. With respect to each Paired Program, Jounce hereby grants to Celgene an exclusive Option, exercisable at any time during the applicable Option Term, to enter into a Development & Commercialization Agreement for each such Paired Program (including all applicable Collaboration Candidates of such Paired Program) and any related Diagnostic Products developed therefor, as set forth in and on the terms and conditions set forth in the Development & Commercialization Agreement (and each applicable Collaboration Candidate under such Paired Program shall be deemed a “Co-Co Candidate” thereunder).

3.1.6 Bundled Programs.

(a) With respect to any of the Other Programs (including, for

the avoidance of doubt, the Lead Program) that is a Bundled Program, if Jounce advances a Bundled Macrophage Collaboration Candidate for a Bundled Macrophage Program or a Bundled B-Cell/Treg Collaboration Candidate for a Bundled B-Cell/Treg Program and obtains an IND Approval from the FDA for such Collaboration Candidate, then each additional Bundled Macrophage Program or Bundled B-Cell/Treg Program that is advanced after the first Bundled Macrophage Program or Bundled B-Cell/Treg Program, as applicable for which Jounce obtains an IND Approval from the FDA (each, an “Additional Bundled Program”) shall be offered as an additional Option to Celgene in accordance with Section 3.1.6(b) (and for clarity, each such Option shall not count towards Celgene’s maximum Option exercise Option Cap under Section 3.1).

(b) With respect to each Additional Bundled Program, Jounce hereby grants to Celgene an exclusive Option, exercisable at any time during the applicable Option Term, to enter into a Development & Commercialization Agreement for such Additional Bundled Program (including all applicable Collaboration Candidates of such Additional Bundled Program that are Immune Activators or Immune Suppressors, as applicable, but not both Immune Activators and Immune Suppressors, and Program-Specific Reagents thereunder) and any related Diagnostic Products developed therefor, as set forth in and on the terms and conditions set forth in the Development & Commercialization Agreement (and each applicable Collaboration Candidate under such Additional Bundled Program shall be deemed a “Co-Co Candidate” thereunder).

(c) In the event that Celgene exercises its Option for an Additional Bundled Program in accordance with Section 3.1.6(b), the Parties understand and agree that such Additional Bundled Program shall not count as a distinct Program from the corresponding Bundled Program solely for purposes of counting towards the Option Cap with respect to Celgene’s permitted exercise of up to a maximum of six (6) Options pursuant to Section 3.1. Notwithstanding the foregoing, any such Additional Bundled Program for which Celgene exercises its Option shall otherwise be treated as an Other Program for purposes of this Agreement, including for the avoidance of doubt (i) the triggering events for delivery of an IND Data Package for such Other Program, and (ii) Celgene’s opt-in, royalty and milestone payment obligations for such Program pursuant to this Agreement and the applicable Development & Commercialization Agreement, as if such Additional Bundled Program were an Other Program. For example:

(i) If the Available Target for the first Other Program for which Celgene exercises its Option is part of the same Bundled Target Group as the Available Target for the Lead Program then, notwithstanding the fact that such first Other Program shall not count towards the Option Cap, such Option exercise shall be for the “First Other Program” hereunder, the Parties shall enter into a Jounce Lead Co-Development and Co-Commercialization for such Other Program, and Celgene shall pay the amount set forth in Section 6.4.4.

(ii) If the Available Target for the second Other Program for which Celgene exercises its Option is part of the same Bundled Target Group as either the Available Target for the Lead Program or the Available Target for the First Other Program (each of which Options have been previously been exercised by Celgene) then, notwithstanding

the fact that such second Other Program shall not count towards the Option Cap, such Option exercise shall be for the second “Other Program” hereunder, the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization for such Other Program, and Celgene shall pay the amount set forth in Section 6.4.5.

(iii) If Celgene exercises its Option for any Other Program after it has exercised its Option for three (3) Other Programs (or four (4) Other Programs where Jounce has terminated the ICOS Activator Program) and either (A) the Available Target for the next Other Program is part of the same Bundled Target Group for any of the previously exercised Other Programs or (B) the Available Target for the such additional Other Program is not part of a Bundled Target Group for which an Option has previously been exercised, but Celgene has not yet reached the Option Cap (because one (1) or more of such previous Option exercises constituted a Bundled Program and therefore did not count towards the Option Cap), then, the Parties shall enter into a Celgene Lead Co-Development and Co-Commercialization for such Other Program, and Celgene shall pay the amount set forth in Section 6.4.6.

(iv) For two Bundled Targets (e.g Target A and Target B) that are in the same Bundled Target Group, if Celgene has previously exercised an Option for the Program for Immune Activating Collaboration Candidates for Target A as the First Other Program, then subsequently (x) Celgene shall be entitled to exercise an Option for the Program for Immune Suppressing Collaboration Candidates for Target A, and the two (2) separate Programs (one for Immune Activating Collaboration Candidates and one for Immune Suppressing Collaboration Candidates) for Target B, and upon Celgene’s exercise of each such Option, Celgene shall pay first an Option payment under 6.4.5 (if no other Options have been exercised in the interim), and then shall pay two (2) Option payments under Section 6.4.6 (for the subsequent two (2) Programs for which it exercises its Option), and (y) the exercise of such four (4) Options shall only count as one (1) Option exercise towards the Option Cap.

3.1.7 Option Exercise; Lapsed Targets.

(a) On a Program-by-Program basis, during the applicable Option Term, Celgene shall have the right, but not the obligation, to exercise the Option for such Program in its sole discretion by delivering written notice of such exercise (the “Option Exercise Notice”) to Jounce. Within [***] following each Option Exercise Notice delivery, and subject to this Section 3.1.7 and Section 3.2, each of Celgene (or an Affiliate designated by Celgene) and Jounce agree to enter into the applicable Development & Commercialization Agreement described below in this Section 3.1.7 with respect to such Program and will update the exhibits and schedules thereto. On a Collaboration Target-by-Collaboration Target basis, if Celgene fails to provide its Option Exercise Notice with respect to each of the Immune Activating and the Immune Suppressing Program for such Collaboration Target before the expiration of the applicable Option Term, then such Collaboration Target for which the applicable Collaboration Candidates are Specifically Directed shall be deemed a “Lapsed Target”. The Parties shall enter into (a) for the ICOS Activator Program, a Jounce Lead Co-Development and Co-Commercialization Agreement, (b) for the PD-1 Activator Program, the PD-1 License Agreement, (c) subject to Section 2.1.7, for the Lead Program, a Celgene Lead Co-Development and Co-Commercialization Agreement, (d) subject to Section 2.1.7 and in accordance with Section 3.1.4, for the First Other Program for which Celgene exercises an

Option, a Jounce Lead Co-Development and Co-Commercialization Agreement; and (e) subject to Section 2.1.7, for all Other Programs (including any Bundled Programs and/or Paired Programs) that are not the First Other Program, a Celgene Lead Co-Development and Co-Commercialization Agreement. Notwithstanding anything to the contrary herein, Jounce shall have the right to opt-out of its co-development and co-commercialization rights under any Jounce Lead Co-Development and Co-Commercialization Agreement or Celgene Lead Co-Development and Co-Commercialization Agreement, pursuant to the terms set forth in such agreements.

(b) Celgene shall not have the right to exercise its Option with respect to any Lapsed Program or Lapsed Target, and no Lapsed Program or Lapsed Target shall be subject to Sections 5.1 and 5.2.

3.1.8 Covenants During Option Term or Research Term. Except as otherwise permitted under this Agreement or a Development & Commercialization Agreement, on a Program-by-Program basis, commencing on the Effective Date until expiration of the applicable Option Term for such Program or the Research Term (as applicable, and including any extension for ICOS Activator Program pursuant to Section 3.1.1(b)), neither Jounce nor its Affiliates will (a) assign, transfer, convey, encumber (including any liens or charges, but excluding any licenses, which are the subject of subsection (b) below) or dispose of, or enter into any agreement with any Third Party or any entity that is Third Rock Portfolio Company for such period of time in which any Third Rock Fund controls more than [***] to assign, transfer, convey, encumber (including any liens or charges, but excluding any licenses, which are the subject of subsection (b) below) or dispose of, any assets specifically related to a Program, including with respect to any such Program’s Pre-LO Targets, Collaboration Targets, Collaboration Candidates, Development Candidates, or Collaboration IP (such assets the “Program Assets”), except in each case to the extent such assignment, transfer, conveyance, encumbrance or disposition would not conflict with or adversely affect in any respect any of the rights granted to Celgene hereunder or under any Development & Commercialization Agreement, (b) license or grant to any Third Party or any entity that is Third Rock Portfolio Company for such period of time in which any Third Rock Fund controls more than [***], or agree to license or grant to any Third Party or any entity that is Third Rock Portfolio Company for such period of time in which any Third Rock Fund controls more than [***], any rights to any Program Assets if such license or grant would conflict with or adversely affect in any respect any of the rights granted to Celgene hereunder or under any Development & Commercialization Agreement, or (c) disclose any Confidential Information relating to the Program Assets to any Third Party or any entity that is Third Rock Portfolio Company for such period of time in which any Third Rock Fund controls more than [***] if such disclosure would impair or conflict in any respect with any of the rights granted to Celgene hereunder or under any Development & Commercialization Agreement. Notwithstanding the foregoing, an assignment of any Program Assets by Jounce in accordance with Section 12.4.3 shall not be a breach of this Section 3.1.8.

3.2 Government Approvals.

3.2.1 Efforts. Each of Jounce and Celgene will use its commercially reasonable good faith efforts to eliminate any concern on the part of any Governmental Authority regarding the legality of any proposed Development & Commercialization Agreement including, if

required by federal or state antitrust authorities, promptly taking all steps to secure government antitrust clearance, including cooperating in good faith with any government investigation including the prompt production of documents and information demanded by a second request for documents and of witnesses if requested. Notwithstanding anything to the contrary in this Agreement, this Section 3.2.1 and the term “commercially reasonable good faith efforts” do not require that either Party (i) offer, negotiate, commit to or effect, by consent decree, hold separate order, trust or otherwise, the sale, divestiture, license or other disposition of any capital stock, assets, rights, products or businesses of Jounce, Celgene or their respective Affiliates, (ii) agree to any restrictions on the businesses of Jounce, Celgene or their respective Affiliates, or (iii) pay any amount or take any other action to prevent, effect the dissolution of, vacate, or lift any decree, order, judgment, injunction, temporary restraining order, or other order in any suit or proceeding that would otherwise have the effect of preventing or delaying the transactions contemplated by any proposed Development & Commercialization Agreement.

3.2.2 HSR Filings. Each of Jounce and Celgene will, within [***] after the execution of a Development & Commercialization Agreement (or such later time as may be agreed to in writing by the Parties) file with the U.S. Federal Trade Commission (“FTC”) and the Antitrust Division of the U.S. Department of Justice (“DOJ”) any HSR Filing required of it under the HSR Act in the reasonable opinion of either Party with respect to the transactions contemplated by such Development & Commercialization Agreement. The Parties shall cooperate with one another to the extent necessary in the preparation of any such HSR Filing. Each Party shall be responsible for its own costs, expenses, and filing fees associated with any HSR Filing; provided, however, the Parties shall equally share all fees (other than penalties that may be incurred as a result of actions or omissions on the part of a Party, which penalties shall be the sole financial responsibility of such Party), required to be paid to any Governmental Authority in connection with making any such HSR Filing. In the event that the Parties make an HSR Filing under this Section 3.2.2, the relevant Development & Commercialization Agreement shall terminate (i) at the election of either Party, immediately upon notice to the other Party, in the event that the FTC or DOJ obtains a preliminary injunction under the HSR Act against the Parties to enjoin the transactions contemplated by such Development & Commercialization Agreement, or (ii) at the election of either Party, immediately upon notice to the other Party, in the event that the HSR Clearance Date shall not have occurred on or prior to [***] after the effective date of the HSR Filing. Notwithstanding anything to the contrary contained herein, except for the terms and conditions of this Section 3.2.2, none of the terms and conditions contained in a Development & Commercialization Agreement shall be effective until the “Implementation Date,” which is agreed and understood to mean the later of (A) the execution date of the Development & Commercialization Agreement, (B) if a determination is made pursuant to this Section 3.2.2 that a notification of this Agreement is not required to be made under the HSR Act, the date of such determination, or (C) if notification of the Development & Commercialization Agreement is required to be made under the HSR Act, the HSR Clearance Date. As used herein: (x) “HSR Clearance Date” means the earliest date on which the Parties have actual knowledge that all applicable waiting periods under the HSR Act with respect to the transactions contemplated by a Development & Commercialization Agreement have expired or have been terminated; and (y) “HSR Filing” means a filing by Jounce and Celgene with the FTC and the DOJ of a Notification and Report Form for Certain Mergers and Acquisitions (as that term is defined in the HSR Act) with respect to the matters set forth in the Development & Commercialization Agreement, together with all required documentary attachments thereto.

3.2.3 Information Exchange. Each of Jounce and Celgene will, in connection with any HSR Filing, (i) reasonably cooperate with each other in connection with any communication, filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party; (ii) keep the other Party and/or its counsel informed of any communication received by such Party from, or given by such Party to, the FTC, the DOJ or any other U.S. or other Governmental Authority and of any communication received or given in connection with any proceeding by a private party, in each case regarding the transactions contemplated by any proposed Development & Commercialization Agreement; (iii) consult with each other in advance of any meeting or conference with the FTC, the DOJ or any other Governmental Authority or, in connection with any proceeding by a private party, with any other Person, and to the extent permitted by the FTC, the DOJ or such other Governmental Authority or other Person, give the Parties and/or their counsel the opportunity to attend and participate in such meetings and conferences; and (iv) permit the other Party and/or its counsel to review in advance any submission, filing or communication (and documents submitted therewith) intended to be given by it to the FTC, the DOJ or any other Governmental Authority; provided, that materials may be redacted to remove references concerning the valuation of the business of Jounce. Jounce and Celgene, as each deems advisable and necessary, may reasonably designate any competitively sensitive material to be provided to the other under this Section 3.2.3 as “Antitrust Counsel Only Material.” Such materials and the information contained therein shall be given only to the outside antitrust counsel of the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (Jounce or Celgene, as the case may be) or its legal counsel.

3.2.4 Assistance. Subject to this Section 3.2, Jounce and Celgene shall cooperate and use respectively all reasonable efforts to make all other registrations, filings and applications, to give all notices and to obtain as soon as practicable all governmental or other consents, transfers, approvals, orders, qualifications, authorizations, permits and waivers, if any, and to do all other thing necessary or desirable for the consummation of the transactions as contemplated hereby.

3.2.5 No Further Obligations. If a Development & Commercialization Agreement is terminated pursuant to this Section 3.2, then, notwithstanding any provision in this Agreement to the contrary, neither Party shall have any further obligation to the other Party with respect to the subject matter of such Development & Commercialization Agreement; provided, that Celgene shall be permitted to assign such Development & Commercialization Agreement or any rights or obligations related thereto, if required to comply with any Antitrust Law.

If the JSC cannot agree on a matter for which the JSC has decision-making authority within [***] after it has met and attempted to reach such decision, then, either Party may, by written notice to the other, have such issue referred to the Executive Officers for resolution. The Parties’ respective Executive Officers shall meet within [***] after such matter is referred to them, and shall negotiate in good faith to resolve the matter. If the Executive Officers are unable to resolve the matter within

[***], or such other longer time frame the Executive Officers may otherwise agree upon, after the matter is referred to them in accordance with this Section 4.2.5, then: (a) if the matter in dispute relates to activities under a Program prior to Celgene’s exercise of the Option for such Program, then Jounce shall have the final decision making authority; (b) if the matter in dispute relates to activities under the ICOS Activator Program or the First Other Program for which Celgene has exercised its Option, then Jounce shall have the final decision-making authority in the United States and Celgene shall have the final decision making authority in the ROW Territory; (c) if the matter in dispute relates to activities under the Lead Program or any Other Program (including any Bundled Program) for which Celgene has exercised its Option that is not the First Other Program for which Celgene has exercised its Option, then Celgene shall have the final decision making authority worldwide; (d) following Celgene’s exercise of its Option for a Program, for activities or matters arising under such Program’s IDP that do not have global implications for the Program, then the Development Lead Party for such activities under such Program in the territory or country to which such dispute relates shall have the final decision making authority; (e) for activities or matters arising after such Option exercise that (1) are referred by the JSC or that relate to Commercialization of Co-Co Products, and (2) do not have global implications for such Program, the Commercialization Lead Party for the territory or country to which such dispute relates shall have final decision making authority; and (f) subject to the applicable Development & Commercialization Agreement, following Celgene’s exercise of its Option for a Program, for activities or matters arising after such Option exercise that have global implications for such Program, except for those disputes relating to Commercialization, Jounce shall have the final decision making authority for decisions under a Jounce Lead Co-Development and Co-Commercialization Agreement, and Celgene shall have the final decision making authority under a Celgene Lead Co-Development and Co-Commercialization Agreement. The Parties understand and agree that any JSC disagreements with respect to the PD-1 License Agreement shall be resolved in accordance with the terms of the PD-1 License Agreement and this Article 4 shall not govern, as contemplated by Section 2.2.3 of the PD-1 License Agreement.

Notwithstanding the foregoing, the Party having final decision-making authority shall not have the right to exercise its final decision-making authority to unilaterally: (i) determine that it has fulfilled any obligations under this Agreement, any Development & Commercialization Agreement or that the other Party has breached any obligation under this Agreement or any Development & Commercialization Agreement; (ii) determine that milestone events required for the payment of milestone payments have or have not occurred; (iii) make a decision that is expressly stated to require the mutual agreement or mutual consent of the Parties; (iv) require the conduct of, or restrict the other Party from conducting, Development activities specifically related only to such Party’s territory under a Co-Development and Co-Commercialization Agreement; or (v) otherwise expand its rights or reduce its obligations under this Agreement or any Development & Commercialization Agreement.

During the Research Term, Jounce and its Affiliates shall not, except as otherwise expressly permitted in this Agreement or any applicable Development & Commercialization Agreement: (i) alone or with or for any Third Party, (x) research (including screen) in the Field any Biologic (which, in the case of an Antibody, [***] of any Collaboration Candidate), that is Specifically Directed to a Pre-LO Target or Collaboration Target other than PD-1 (the “Jounce Exclusivity Targets”), or (y) Develop, Manufacture or Commercialize any Biologic in the Field that is Specifically Directed to any Jounce Exclusivity Target, other than in performance of Collaboration activities under this Agreement or a Development & Commercialization Agreement, (ii) grant a license or sublicense to research (including screen), Develop, Manufacture or Commercialize any Biologic in the Field or pharmaceutical product in the Field, in each case described in this clause (ii) as Specifically Directed to Jounce Exclusivity Targets, as part of a Third Party Transaction, or (iii) except as expressly permitted under Section 12.4, transfer, assign, convey or otherwise sell any Biologic or pharmaceutical product described in clause (i) above. Upon exercise of any Option, Jounce understands and agrees that it also shall be bound by the exclusivity provisions set forth in the applicable Development & Commercialization Agreement with respect to the applicable Program. The restrictions described in this Section 5.1 shall not apply to: (A) any Lapsed Targets or any Biologic or pharmaceutical product Specifically Directed to any Lapsed Target; (B) PD-1; (C) to any Excluded Jounce Target, Excluded Celgene Target or Excluded Celgene Program; or (D) with respect to [***], any Biologic that is Specifically Directed to [***]. Jounce hereby agrees it will only Develop Biologics Specifically Directed to a Jounce Exclusivity Target, pursuant to a Program under this Agreement, and for which such Biologic, if a Collaboration Candidate, is subject to an Option under this Agreement. Both Parties understand and agree that, when any Program hereunder becomes a “Lapsed Program”, any Biologics that are Immune Activating or Immune Suppressing, as applicable, and Specifically Directed to the applicable Collaboration Target for such Lapsed Program shall no longer be subject to this Section 5.1.

5.2 Celgene Exclusivity. During the Research Term, Celgene and its Affiliates shall not, except as otherwise expressly permitted in this Agreement or any applicable Development & Commercialization Agreement, on a Program-by-Program basis: (i) [***] (A) [***], (B) [***], or (C) [***], or [***].

5.3 Exceptions. Notwithstanding anything to the contrary contained herein, neither Party shall be deemed in breach of this Section 5 as follows:

5.3.1 Academic Collaborations. Notwithstanding the provisions of Sections 5.1 and 5.2, each Party shall be permitted to perform any of the activities that would otherwise be prohibited under Sections 5.1 and 5.2 and in relation to a given Collaboration Target, if such activities are (a) the subject of an existing agreement between such Party and an academic institution or academic collaborator entered into prior to the Effective Date, provided that such contracting Party shall not be permitted to amend any of such existing agreement’s provisions with respect to (i) ownership and licenses of pre-existing intellectual property rights, as well as intellectual property rights and inventions arising pursuant to the conduct of activities under such agreement, (ii) rights regarding publication of the results arising pursuant to the conduct of activities under such agreement, and (iii) confidentiality obligations (collectively, (i) through (iii), the “Academic Essential Provisions”), in a manner that would result in any of the provisions covered by the Academic Essential Provisions in such existing agreement being less favorable to the contracting Party, or which would adversely affect any rights granted to Celgene or Jounce under this Agreement or any Development & Commercialization Agreement following such amendment without the prior written consent of the other Party (such consent not to be unreasonably withheld), or (b) the subject of an agreement entered into between such Party and an academic institution or academic collaborator after the Effective Date that contains terms and conditions with respect to the Academic Essential Provisions consistent with the terms and conditions of the agreements between such Party and an academic institution or academic collaborator entered into prior to the Effective Date; provided that if any Academic Essential Provisions of an amendment described in (a) or an agreement described in (b) would not be consistent with the Academic Essential Provisions of the agreements between such Party and an academic institution or academic collaborator entered into prior to the Effective Date, such Party shall not enter into such amendment or agreement on such inconsistent terms and conditions without the prior written consent of the other Party, not to be unreasonably withheld.

5.3.2 Competitive Programs. Sections 5.1 and 5.2 shall not apply if, during the Research Term, any Party or its Affiliates merges or consolidates with, or otherwise acquires, a Third Party that is then engaged in activities that would otherwise constitute a breach of this

Section 5 by any Party or its Affiliates (a “Competitive Program”) or acquires by license or otherwise a Competitive Program from a Third Party; it being understood and agreed that, unless the Parties agree otherwise in writing, such Party that is engaged in a Competitive Program (the “Competitive Program Party”) shall, within [***] after the date of such merger, consolidation or acquisition, notify the other Party that it intends to either: (a) terminate, or cause its relevant Affiliate to terminate, the Competitive Program or (b) divest, or cause its relevant Affiliate to divest, whether by license or otherwise, the Competitive Program. If the Competitive Program Party notifies the other Party within such [***] period that it intends to terminate, or cause its relevant Affiliate to terminate, such Competitive Program, the Competitive Program Party or its relevant Affiliate, shall (i) terminate such Competitive Program as quickly as possible, and in any event within [***] (unless applicable Law requires a longer termination period) after the Competitive Program Party delivers such notice to the other Party; and (ii) confirm to the other Party when such termination has been completed, and the Competitive Program Party’s continuation of the Competitive Program during such [***] (or, as required by applicable Law, longer) period shall not constitute a breach of the Competitive Program Party’s exclusivity obligations under Sections 5.1 and 5.2. If the Competitive Program Party notifies the other Party within such [***] period that it intends to divest such Competitive Program, the Competitive Program Party or its relevant Affiliate shall use all reasonable efforts to effect such divestiture as quickly as possible, and in any event within [***] after the Competitive Program Party delivers such notice to the other Party, and shall confirm to the other Party when such divestiture has been completed. If the Competitive Program Party or its relevant Affiliate fails to complete such divestiture within such [***] period, but has used reasonable efforts to effect such divestiture within such [***] period, then, unless otherwise required by applicable Law, such [***] period shall be extended for such additional reasonable period thereafter as is necessary to enable such Competitive Program to be in fact divested, not to exceed an additional [***]; provided that such additional [***] period shall be extended for such period as is necessary to obtain any governmental or regulatory approvals required to complete such divestiture if the Competitive Program Party or its relevant Affiliate is using good faith efforts to obtain such approvals. The Competitive Program Party’s continuation of the Competitive Program during such divestiture period shall not constitute a breach of the Competitive Program Party’s exclusivity obligations under Sections 5.1 and 5.2.

5.3.3 Certain Permitted Activities.

(a) The [***] shall not constitute a breach of Section 5.1 or 5.2, as applicable. Each Party shall report to the JSC on a Calendar Quarterly basis [***], as applicable. For clarity, providing at market price any supply of any biological or pharmaceutical product owned or controlled by a Party or any of its Affiliates that is then being commercialized without violation of Section 5.1 or 5.2, as applicable, to a Third Party conducting a human clinical trial with respect to a compound in the Field for the Territory shall not constitute development in violation of such Party’s exclusivity obligations under this Article 5 as long as neither such Party nor any of its Affiliates receives any other monetary consideration with respect to any product other than such product that is the subject of such clinical trial.

(b) The entry into any Funding Agreement by Celgene or its Affiliates, either before or after the Effective Date, and the performance by Celgene or its Affiliates of any obligations thereunder shall not constitute a breach of Section 5.2; provided that

any exercise of any options with respect to licensing any intellectual property rights by Celgene or its Affiliates thereunder shall be subject to the provisions set forth in Section 5.2 and shall not be permitted under this Section 5.3.3(b).

(c) The restrictions set forth in Section 5.1 or 5.2, as applicable, shall not be deemed to prevent either Party or its respective Affiliates from (A) fulfilling its obligations under this Agreement, and (B) engaging any subcontractors in accordance with Section 2.6 of this Agreement.

(d) If a Change of Control occurs with respect to either Party with a Third Party and the Third Party already is conducting or is planning, as of the effective date of such Change of Control, to conduct activities that would cause a Party or an Affiliate to violate Section 5.1 or 5.2, as applicable, (an “Acquirer Program”), then such Third Party will be permitted to continue such Acquirer Program and such initiation or continuation will not constitute a violation of Section 5.1 or 5.2, as applicable; provided that (i) none of the Collaboration IP or Joint Collaboration IP will be used in any Acquirer Program, (ii) none of the other Patents or Know-How licensed by either Party to the other Party pursuant to this Agreement will be used in any Acquirer Program, (iii) no Confidential Information of the other Party will be used in any such Acquirer Program, and (iv) the research or Development activities required under this Agreement will be conducted separately from any research or development activities directed to such Acquirer Program, including by the maintenance of separate lab notebooks and records (password-protected to the extent kept on a computer network) and the use of separate personnel working on each of the activities under this Agreement, and the activities covered under such Acquirer Program (except that this requirement shall not apply to personnel who have senior research management roles and not project level research roles, provided such personnel in senior research management roles are not directly involved in the day-to-day activities under such Acquirer Program).

(e) Notwithstanding anything to the contrary contained herein, each Party shall have, at all times, the right to conduct cell-based screens directed toward cell phenotypes, even if such cell-based screens result in the unanticipated identification or discovery of any Target, and such activities shall not constitute a violation of this Article 5.

5.3.4 Supply of Biologics. Both Parties shall at all times have the right to supply any Biologic owned or Controlled (other than under a Development & Commercialization Agreement) by such Party that is then being commercialized to a Third Party conducting a Clinical Trial for a combination therapy involving such supplied Biologic so long as such supply of such Biologic to such Third Party is at a then-prevailing market price.

(b) Back-Up Right. If Jounce in any country decides not to file a Collaboration Patent Controlled by Jounce or intends to allow such Patent to lapse or become abandoned without having first filed a substitute, it shall notify and consult with Celgene of such decision or intention at least [***] prior to the date upon which the subject matter of such Patent shall become unpatentable or such Patent shall lapse or become abandoned, and Celgene shall thereupon have the right (but not the obligation) to assume the Prosecution and Maintenance thereof at Celgene’s expense with counsel of its choice.

(c) Filing and Prosecution of New Patents. For any Patent that is first filed after the Effective Date that Covers the composition of matter of a Development Candidate for which Jounce is responsible for Prosecution and Maintenance pursuant to Section 7.3.1(a), Jounce shall file such Patents in every country listed in Schedule 7.3.1(c) (the “Core Countries”). If Celgene wishes to Prosecute and Maintain such Patent in countries other than the Core Countries, it may so notify Jounce in writing. Following Jounce’s receipt of such notice, subject to Section 7.3.1(a)(ii), Jounce shall pursue the Prosecution and Maintenance of such Patent in the countries designated in such Celgene notice, and Celgene shall reimburse to Jounce all expenses incurred by Jounce in connection with the Prosecution and Maintenance of such Patent in such non-Core Countries. On a Program-by-Program basis and after Celgene’s exercise of its Option with respect to such Program, for any Patent that is first filed that Covers compositions of matter or methods of use of a Collaboration Candidate, Prosecution and

Maintenance of such Patent shall be conducted in accordance with the applicable Development & Commercialization Agreement for such Program.

(d) Celgene Patents. As between the Parties, Celgene shall have the sole right (but not the obligation) to Prosecute and Maintain the Collaboration Patents solely owned by Celgene (the “Celgene Patents”), at its cost. Celgene shall keep Jounce informed as to material developments with respect to the Prosecution and Maintenance of Celgene Patents. Celgene shall provide or make reasonably available to Jounce copies of all substantive office actions or any other substantive documents that Celgene receives from any patent office, including notice of all interferences, reissues, re-examinations, inter partes, review, post grant proceedings, oppositions or requests for patent term extensions. Celgene shall also provide Jounce with a reasonable opportunity to substantively comment on the Prosecution and Maintenance of such Patents prior to taking material actions (including the filing of initial applications), and will in good faith consider any comments by and actions recommended by Jounce; provided however that Jounce does so promptly and consistent with any applicable filing deadlines. If Celgene decides not to file any Collaboration Patent for which it is responsible for Prosecution and Maintenance pursuant to Section 7.3.2(a) and this Section 7.3.1(d) or intends to allow any such Patent to lapse or become abandoned in any country without having first filed a substitute, it shall notify and consult with Jounce of such decision or intention at least [***] prior to the date upon which the subject matter of such Patent shall become unpatentable or such Patent shall lapse or become abandoned, and Jounce shall thereupon have the right (but not the obligation) to assume the Prosecution and Maintenance thereof at Jounce’s expense with counsel of its choice. With respect to any Celgene Independent Products, Celgene retains the right to Prosecute and Maintain any Patents solely Covering such Celgene Independent Products, including allowing such Patent to lapse or become abandoned.

(e) Notwithstanding anything in this Section 7.3.1 to the contrary, Celgene shall have final decision-making authority as to representations made to any patent office worldwide with respect to any Celgene Independent Products.

7.3.2 Joint Collaboration Patents.

(a) Generally.

(i) As between the Parties, Jounce shall have the first right (but not the obligation) to Prosecute and Maintain the Joint Collaboration Patents that Cover an Invention in a Program prior to Celgene’s exercise of the Option for such Program, and Prosecution and Maintenance of such Joint Collaboration Patents arising from activities conducted in a Program after Celgene’s exercise of the Option for such Program shall be conducted in accordance with the applicable Development & Commercialization Agreement.

(ii) To the extent any Joint Collaboration Patent is directed both to a Collaboration Candidate and a Celgene Independent Product that is not Specifically Directed to one of the Pre-LO Targets or Collaboration Targets, prosecution of such Patent shall be by Jounce prior to Celgene’s exercise of the relevant Option and pursuant to the applicable Development & Commercialization Agreement after Celgene’s exercise of the relevant Option.

(b) Back-Up Right. If the Party responsible for Prosecution and Maintenance of a Joint Collaboration Patent pursuant to Section 7.3.2(a)(ii) in any country decides not to file such Joint Collaboration Patent or intends to allow such Joint Collaboration Patent to lapse or become abandoned without having first filed a substitute, it shall notify and consult with the other Party of such decision or intention at least [***] prior to the date upon which the subject matter of such Joint Collaboration Patent shall become unpatentable or such Joint Collaboration Patent shall lapse or become abandoned, and such other Party shall thereupon have the right (but not the obligation) to assume the Prosecution and Maintenance thereof at such other Party’s expense with counsel of its choice.

(c) Notwithstanding anything in this Section 7.3.2 to the contrary, Celgene shall have final decision-making authority as to representations made to any patent office worldwide with respect to any Celgene Independent Products.

7.3.3 Cooperation in Prosecution and Maintenance.

(a) Further Assurances. Each Party agrees to make its employees, agents and consultants reasonably available to the other Party (or to the other Party’s authorized attorneys, agents or representatives), to the extent reasonably necessary to enable the Party responsible for the Prosecution and Maintenance of a Patent in accordance with this Section 7.3 or any Development & Commercialization Agreement to undertake such Prosecution and Maintenance, and shall assist in any license registration processes with applicable Governmental Authorities that may be available for the protection of a Party’s interests in this Agreement or any Development & Commercialization Agreement. In the event of any termination of a Party’s license rights under this Agreement or any Development & Commercialization Agreement, the Party with a license registration related to such terminated license rights shall promptly cooperate with any request by the other Party to terminate any such registration relating to the terminated license rights.

(b) Assistance. The Parties shall cooperate with one another, through the Patent Committee including their respective Patent Liaisons, to file and prosecute the Patents for which Jounce is responsible for Prosecution and Maintenance pursuant to Section 7.3.1(a) or for which Celgene is responsible for Prosecution and Maintenance pursuant to Section 7.3.1(d), Joint Collaboration Patents and Celgene Patents for which either Party is responsible for Prosecution and Maintenance pursuant to this Section 7.3 or any Development & Commercialization Agreement, including in the furtherance of the Patent Strategy, with respect to Collaboration Candidates, and Development Candidates. At either Party’s request, the Parties shall cooperate with one another to file and prosecute continuing or divisional Patent applications with respect to Patents for which Jounce is responsible for Prosecution and Maintenance pursuant to Section 7.3.1(a) or for which Celgene is responsible for Prosecution and Maintenance pursuant to Section 7.3.1(d), Joint Collaboration Patents and Celgene Patents, in each case that are primarily applicable to a Collaboration Candidate if practicable and if necessary or desirable to divide subject matter primarily relating to the development, manufacture or commercialization of one or more Collaboration Candidates or Development Candidates or products from other subject matter.

7.3.4 Costs of Prosecution and Maintenance. Prior to Celgene’s exercise of an Option with respect to a Program, each Party shall be responsible for all costs and expenses associated with its Prosecution and Maintenance activities under Section 7.3 with respect to Patents related to such Program for which it is responsible pursuant to Sections 7.3.1 or 7.3.2 and after such Option exercise pursuant to the applicable Development & Commercialization Agreement.

7.4 Defense of Claims Brought by Third Parties. If a Party becomes aware of any actual or potential claim that the research, Development, Manufacture or Commercialization of any Available Target, Biologic or Collaboration Candidate being researched, Developed, Manufactured or Commercialized pursuant to this Agreement or a Development & Commercialization Agreement, infringes the intellectual property rights of any Third Party, such Party shall promptly notify the other Party. In any such instance, the Parties shall as soon as practicable thereafter meet (which may be through the JSC) to discuss in good faith regarding the best response to such notice. Certain additional rights and obligations of the Parties with respect to any such claim will be set forth in the Development & Commercialization Agreement for such Program (in each case if applicable).

7.5 Enforcement of Patents Prior to Exercise of Option.

Unless stated otherwise in a Development & Commercialization Agreement, on a Program-by-Program and country-by-country basis, within applicable time limits after such Program’s Biologic has received marketing authorization by a governmental authority, Jounce and Celgene shall discuss and seek to reach mutual agreement as to which, if any, of the Patents within the Jounce Patents or Celgene Patents, or Joint Collaboration Patents, in each case that Cover Collaboration Candidates, and Development Candidates, or Products containing such Collaboration Candidates, and Development Candidates, for which the Parties shall apply to obtain patent term extensions, adjustments, restorations, or supplementary protection certificates under applicable Laws, based on the best commercial interests of such Collaboration Candidates and Development Candidates and Products; it being understood and agreed that, (a) if Celgene seeks a patent term extension, then Jounce agrees to negotiate in good faith with respect to any measures required by applicable Law for Celgene to obtain such extension, and (b) if Jounce seeks a patent term extension, then Celgene agrees to negotiate in good faith with respect to any measures required by applicable Law for Jounce to obtain such extension. If the Parties are unable to reach mutual agreement and unless stated otherwise in a Development & Commercialization Agreement: (i) prior to exercise of the Option for such Program, Jounce shall have the right to make the final decision with respect to all Patents; and (ii) after exercise of the Option for such Program, patent term extension decisions shall be made in accordance with the applicable Development & Commercialization Agreement.

7.7 Common Interest Agreement. The Parties shall negotiate in good faith to enter into a common interest agreement within [***] after the Effective Date.

7.8 Third Party Licenses.

7.8.1 Notice. On a Program-by-Program basis, if, at any time during the Term, either Party reasonably determines that any Third Party intellectual property rights may be necessary for the Development, Manufacture or Commercialization of any Collaboration Candidate or Biologic that is the subject of research, Development, Manufacture and/or Commercialization efforts under this Agreement or any Development & Commercialization Agreement, then such Party will promptly notify the JSC and the Patent Committee. [***].

7.8.2 Discussion. After receiving the notification provided in Section 7.8.1, the Patent Committee, in consultation with the Patent Liaisons will discuss whether the Parties should obtain one or more licenses from one or more Third Parties for the activities described in Section 7.8.1 or take other appropriate measures in view of such Third Party rights, such as whether the Parties should obtain an opinion relating to such Third Party intellectual property rights, or take alternative approaches to avoid using such Third Party intellectual property rights.

7.8.3 Pre-Option.

(a) Prior to Celgene’s exercise of the Option for a Program, if the Patent Committee determines in accordance with Section 7.8.2 that the Parties should obtain one or more licenses from one or more Third Parties for the activities described in Section 7.8.1, and the Parties agree with such determination, then Jounce shall use Commercially Reasonable Efforts to obtain a license to such Third Party intellectual property rights (such license, a “Third Party License”), with the right to sublicense such Third Party intellectual property rights to the other Party to the extent necessary for the other Party to exercise its rights and conduct its obligations under this Agreement or any Development & Commercialization Agreement. Prior to Celgene’s exercise of the Option for a Program, Celgene may elect to participate or be consulted in any negotiations for such Third Party License and, if Celgene will bear any obligation under such resulting Third Party License or share costs under Section 7.8.5 or the terms of any Development & Commercialization Agreement with respect to such Third Party License, then Celgene must approve the terms of such Third Party License prior to Jounce executing such Third Party License. With respect to potential licenses from [***] as described in Section 7.8.1, prior to Jounce initiating a campaign with [***] to discover Antibodies that may become Collaboration Candidates in an Other Program, the Parties agree that the milestone payments and royalty payments that may be owed to [***] as a result of Manufacturing, Developing and/or Commercializing such Collaboration Candidates will be allocated between the Parties if Celgene subsequently exercises its Option with respect to such Other Program and enters into a Development & Collaboration Agreement with respect thereto, as follows: (i) such payments arising from Development anywhere in the Territory as part of the Parties’ joint global development will be deemed Worldwide Development Costs; (ii) such payments arising from Development or Commercialization in the ROW Territory by Celgene, its Affiliates or Sublicensees for the purpose of ROW Administration will be paid by Celgene, provided that Celgene shall be entitled to reductions in Celgene’s royalty payment obligations to Jounce in accordance with the provisions of the applicable Development & Commercialization Agreement as if such payments were for licenses under Third Party Patents; and (iii) such payments arising as a result of Commercialization in the United States will be treated as COGs under the applicable Development & Collaboration Agreement.

(b) If the Parties do not agree with the Patent Committee’s determination to obtain a Third Party License, then prior to Celgene’s exercise of the Option for a Program, Celgene shall have the right to obtain such Third Party License, at its sole cost and expense. If Jounce obtains a Third Party License without the agreement of Celgene, then the rights granted to Jounce under such Third Party License shall not be deemed to be Controlled by Jounce; provided, however that, after Celgene exercises an Option, such rights shall only be deemed Controlled by Jounce upon Celgene’s written consent. In the event that Celgene gives such consent, Celgene shall reimburse a reasonable, applicable portion of amounts previously

paid by Jounce to the Third Party licensor for such Third Party License prior to the date of Celgene’s consent to such Third Party License, and Section 7.8.5 shall apply. If Jounce obtains a Third Party License under Section 7.8.3(a), and Celgene does not provide its consent to such Third Party License as provided in Section 7.8.3(a), Jounce shall be solely responsible for all fees, expenses and royalties associated with the exercise of Jounce’s rights under such Third Party License and Celgene shall not have any sublicense under such Third Party License.

7.8.4 Post-Option. Following the exercise of the Option for a Program and subject to the applicable Development & Commercialization Agreement, if Celgene reasonably determines that any Third Party intellectual property rights may be necessary for the Development, Manufacture, or Commercialization of a Collaboration Candidate or Diagnostic Product that is the subject of research, Development, Manufacture and/or Commercialization efforts under this Agreement or such Development & Commercialization Agreement, Celgene shall have the right, but not the obligation, to obtain a license to such Third Party intellectual property, with the right to sublicense, in order to permit Celgene to conduct its obligations and exercise its rights under such Development & Commercialization Agreement. The terms and conditions involved in obtaining such rights shall be determined at Celgene’s sole discretion and expense (subject to Section 7.8.5); provided, however, that if Jounce would be required to practice such Third Party intellectual property rights to perform its obligations under this Agreement or any Development & Commercialization Agreement, Celgene shall structure such Third Party License to allow Celgene to grant to Jounce a sublicense thereunder. The costs of such Third Party License shall be borne as provided in Section 7.8.5.

7.8.5 Costs. The costs associated with the exercise of rights under any Third Party License obtained under Section 7.8 shall be borne as follows:

(a) Unless otherwise agreed by the Parties in writing, the costs associated with negotiating and obtaining such Third Party License shall be borne in accordance with Section 7.8.5(b), provided that if such Third Party License is obtained with respect to a Program that is subject to a Co-Development and Co-Commercialization Agreement, such costs shall be included as an Allowable Expense in accordance with the terms of the applicable Co-Development and Co-Commercialization Agreement; and

(b) If (i) the Parties agree to obtain a Third Party License or if Celgene provides consent to a Third Party License as provided in Section 7.8.3, or (ii) if Celgene elects to obtain a Third Party License pursuant to Section 7.8.4, then following the execution of such Third Party License (or Celgene’s consent, whichever is later), all fees, expenses and royalties incurred by Celgene that are associated with the exercise of rights under such Third Party License shall be borne as described in the royalty anti-stacking provisions described in the applicable Development & Commercialization Agreement.

ARTICLE 8.
CONFIDENTIALITY

8.1 Nondisclosure. Each Party agrees that a Party (the “Receiving Party”) receiving Confidential Information of any other Party (the “Disclosing Party”) shall (a) maintain in confidence such Confidential Information using not less than the efforts such Receiving Party

uses to maintain in confidence its own proprietary information of similar kind and value, but in no event less than a reasonable degree of efforts, (b) not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below, and (c) not use such Confidential Information for any purpose except those expressly permitted by this Agreement (it being understood that this clause (c) shall not create or imply any rights or licenses not expressly granted under this Agreement). The obligations of confidentiality, non-disclosure and non-use under this Section 8.1 shall be in full force during the Term and for a period of [***] thereafter. Each Party, upon the request of the other Party, will return all copies of or destroy (and certify such destruction in writing) the Confidential Information disclosed or transferred to it by the other Party pursuant to this Agreement, within [***] of such request or, if earlier, the termination or expiration of this Agreement; provided however that a Party may retain (i) Confidential Information of the other Party which expressly survives such termination pursuant to this Agreement, and (ii) one (1) copy of all other Confidential Information in archives solely for the purpose of establishing the contents thereof. Notwithstanding anything to the contrary in this Agreement, Jounce will keep confidential, and will cause its employees, consultants, licensees, sublicensees, professional advisors and Affiliates to keep confidential, the Jounce IP, and Celgene will keep confidential, and will cause its employees, consultants, licensees, sublicensees, professional advisors and Affiliates to keep confidential, the Celgene IP, in each case on confidentiality terms at least as protective as the confidentiality provisions of this Agreement (without regard to Section 8.2, other than Section 8.2.3).

8.2 Exceptions. The obligations in Section 8.1 shall not apply with respect to any portion of the Confidential Information of the Disclosing Party that the Receiving Party can show by competent written proof:

8.2.1 was known to the Receiving Party or any of its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party;

8.2.2 is subsequently disclosed to the Receiving Party or any of its Affiliates by a Third Party lawfully in possession thereof and without any obligation to keep it confidential or any restriction on its use;

8.2.3 is published by a Third Party or otherwise becomes publicly available or enters the public domain, either before or after it is disclosed to the Receiving Party, without any breach by the Receiving Party of its obligations hereunder; or

8.2.4 is independently developed by or for the Receiving Party or its Affiliates without reference to or reliance upon the Disclosing Party’s Confidential Information.

Notwithstanding anything to the contrary in this Agreement or any Development & Commercialization Agreement, a Receiving Party may use any learning, skills, ideas, concepts, techniques, know-how and information, including general chemistry methodologies and general SAR (structure-activity relationship) concepts, retained in intangible form in the unaided memory of the Receiving Party’s directors, employees, contractors, advisors, agents and other personnel of the Receiving Party who had access to the Disclosing Party’s Confidential

Information (collectively, “Residual Information”) for any purpose, provided that this right to use Residual Information does not represent a license to any Patents Controlled by the Disclosing Party. For purposes of clarity, nothing contained in the preceding sentence gives the Receiving Party the right to publish or otherwise disclose or use the tangible source of any Residual Information for any purpose other than as provided for in this Agreement or any Development & Commercialization Agreement. A personnel’s memory will be considered unaided only if such person has not intentionally memorized the information for the purpose of retaining and/or subsequently recording, publishing, disclosing or using it.

8.3 Authorized Disclosure.

8.3.1 Disclosure. Notwithstanding Section 8.1, the Receiving Party may disclose Confidential Information belonging to the Disclosing Party, and Confidential Information deemed to belong to both the Disclosing Party and the Receiving Party, to the extent (and only to the extent) such disclosure is reasonably necessary in the following instances:

(a) subject to Section 8.5, complying with applicable Laws (including the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) or any national securities exchange) and with judicial process, if in the reasonable opinion of the Receiving Party’s counsel, such disclosure is necessary for such compliance;

(b) disclosure of the other Party’s Confidential Information to any of its officers, employees, consultants, agents or Affiliates or sublicensees (and in the case of Celgene, Sublicensees) if and only to the extent necessary to carry out its responsibilities or exercise its rights under this Agreement; provided that each such disclose is bound by written confidentiality obligations to maintain the confidentiality thereof and not to use such Confidential Information except as expressly permitted by this Agreement;

(c) disclosure, solely on a “need to know basis,” to (i) Affiliates, potential or actual research and development collaborators, subcontractors, advisors (including attorneys and accountants), (ii) subject to Section 8.3.1(d), actual or potential acquirers, investment bankers, investors, lenders, or other potential financial partners, and (iii) in each case of (i) and (ii), their and each of the Parties’ respective directors, employees, contractors and agents; provided, that in all cases of (i), (ii) and (iii), prior to any such disclosure, each disclosee must be bound by written obligations of confidentiality, non-disclosure and non-use no less restrictive than the obligations set forth in this Article 8 (provided, however, that in the case of prospective investment bankers, investors, lenders or other financial partners, the term of confidentiality may be shortened to [***] from the date of disclosure and in the case of legal advisors, no written agreement shall be required), which for the avoidance of doubt, will not permit use of such Confidential Information for any purpose except those permitted by this Agreement; provided, however, that, in each of the above situations, the Receiving Party shall remain responsible for any failure by any Person who receives Confidential Information pursuant to this Section 8.3.1(c) to treat such Confidential Information as required under this Article 8; and

(d) in the case of any disclosure of this Agreement or any executed Development & Commercialization Agreement, to any actual or potential acquirer, or

prospective investment bankers, investors, lenders or other financial partners, such disclosure shall solely be in the form of the redacted version of this Agreement or such Development & Commercialization Agreement, in each case, which version has been agreed upon by the Parties in good faith, including any such redacted version that has been agreed upon for actual or potential filing to the SEC; it being understood and agreed that only after negotiations with any such Third Party have progressed so that such Party reasonably and in good faith believes that consummation of the proposed transaction with such Third Party is imminent, only then may such Party provide an unredacted version of this Agreement or such Development & Commercialization Agreement, to such Third Party.

8.3.2 Terms of Disclosure. If and whenever any Confidential Information is disclosed in accordance with this Section 8.3, such disclosure shall not cause any such information to cease to be Confidential Information except to the extent that such disclosure results in a public disclosure of such information (other than by breach of this Agreement). Where reasonably possible and subject to Section 8.5, the Receiving Party shall notify the Disclosing Party of the Receiving Party’s intent to make any disclosures pursuant to Section 8.3.1 sufficiently prior to making such disclosure so as to allow the Disclosing Party adequate time to take whatever action it may deem appropriate to protect the confidentiality of the information, and the Receiving Party will provide reasonable assistance to the Disclosing Party with respect thereto; provided that, in the event, the Receiving Party will use reasonable measures to ensure confidential treatment of such information and shall only disclose such Confidential Information of the Disclosing Party as is necessary to comply with such Laws or judicial process.

8.4 Terms of this Agreement. The Parties agree that this Agreement and all of the respective terms hereof shall be deemed to be Confidential Information of Jounce and Celgene, and each Party agrees not to disclose any of them without the prior written consent of the other Party, except that each Party may disclose any of them in accordance with the procedures of Section 8.3 (and the provisions related thereto, including, to the extent applicable, the provisions of Section 8.5).

8.5 Securities Filings. Each Party acknowledges and agrees that the other Party may submit this Agreement or any executed Development & Commercialization Agreement to the SEC or any national securities exchange in any jurisdiction (collectively the “Securities Regulators”), and if a Party does submit this Agreement or any such Development & Commercialization Agreement to any Securities Regulators, such Party agrees to consult with the other Party with respect to the preparation and submission of, a confidential treatment request for such agreement. Notwithstanding the foregoing, if a Party is required by applicable Law or any Securities Regulator to make a disclosure of the terms of this Agreement or any Development & Commercialization Agreement in a filing with or other submission to such Securities Regulator, and (a) such Party has provided copies of the disclosure to the other Party as far in advance of such filing or other disclosure as is reasonably practicable under the circumstances, (b) such Party has promptly notified the other Party in writing of such requirement and any respective timing constraints, and (c) such Party has given the other Party a reasonable time under the circumstances from the date of notice by such Party of the required disclosure to comment upon, request confidential treatment or approve such disclosure, then such Party will have the right to make such public disclosure at the time and in the manner reasonably

determined by its counsel to be required by applicable Law. Notwithstanding anything to the contrary herein, it is hereby understood and agreed that if a Party seeking to make a disclosure to a Securities Regulator as set forth in this Section 8.5, and the other Party provides comments within the respective time periods or constraints specified herein or within the respective notice, the Party seeking to make such disclosure or its counsel, as the case may be, will in good faith consider incorporating such comments.

8.6 Publicity.

8.6.1 Press Release. The Parties agree to issue a mutually agreed upon press release promptly after execution of this Agreement. Promptly following the exercise of the Option for a Program, the Parties shall discuss and mutually agree upon a form of press release that may be issued by each Party following the execution of a Development & Commercialization Agreement for such Program and the occurrence of the First Extension, Second Extension or Third Extension, as applicable (but, subject to Section 8.6.1(ii) below, for the avoidance of doubt excluding any amounts paid in connection with such extensions or events). The agreed form of such press release shall be attached as Exhibit E to the applicable Development & Commercialization Agreement.

Notwithstanding the foregoing (i) Jounce shall have the right to disclose the occurrence of any Option exercised by Celgene or milestone achieved by Celgene under this Agreement or any Development & Commercialization Agreement, and solely if required by Applicable Law or securities exchange rule, any corresponding amounts paid by Celgene with respect to such Option exercise or milestone achievement, and (ii) any disclosure that is required by applicable Laws (including the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended) or the rules of any Securities Regulator or the securities regulations of any state or other jurisdiction, or by judicial process shall be in accordance with Sections 8.3 and 8.5, as applicable. Without limiting the foregoing, each Party agrees to provide to the other Party a copy of any public announcement covered by this Section 8.6 as soon as reasonably practicable under the circumstances prior to its scheduled release. Except under extraordinary circumstances, each Party shall provide the other Party with an advance copy of any such announcement at least [***] prior to its scheduled release. Each Party shall have the right to expeditiously review and recommend changes to any such announcement and, except as otherwise required by applicable Laws or such rules or regulations, the Party whose announcement has been reviewed shall remove any Confidential Information of the reviewing Parties that the reviewing Parties deem to be inappropriate for disclosure and request in writing that the publishing Party remove from such announcement within the applicable review period (not to exceed [***] from receipt of such copy).

Celgene shall indemnify, defend and hold harmless Jounce, its Affiliates and its or their respective directors, officers, employees and agents (collectively, the “Jounce Indemnitees”), from and against any and all Third Party Damages to the extent arising out of or relating to, directly or indirectly, from any Claim based upon:

10.1.1 the [***] under this Agreement;

10.1.2 any [***] under this Agreement; or

10.1.3 the [***] described in this Section 10.1.3;

[***]

10.2 Indemnification by Jounce. Jounce shall indemnify, defend and hold harmless Celgene, its Affiliates and its or their respective directors, officers, employees and agents (collectively, the “Celgene Indemnitees”), from and against any and all Third Party Damages to the extent arising out of or relating to, directly or indirectly, from any Claim based upon:

10.2.1 the [***] in connection with [***] under this Agreement;

10.2.2 any [***] under this Agreement; or

10.2.3 the [***] described in this Section 10.2.3;

[***].

10.3 Notice of Claims. A Claim to which indemnification applies under Section 10.1 or Section 10.2 shall be referred to herein as an “Indemnification Claim.” If the Indemnitee intends to claim indemnification under this Article 10, the Party claiming indemnification (the “Indemnitee”) shall notify the indemnifying Party (the “Indemnitor”) in writing, promptly upon becoming aware of an Indemnification Claim, describing in reasonable detail the facts giving rise to the Indemnification Claim; provided, that an Indemnification Claim in respect of any action at law or suit in equity by or against a Third Party as to which indemnification shall be sought shall be given promptly after the action or suit is commenced (provided that the Indemnitee is aware of such commencement); and provided further, that the failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice.

10.4 Indemnification Procedures. If an Indemnitee receives written notice of a Claim that the Indemnitee believes may result in a claim for indemnification under this Article 10, such Indemnitee shall deliver an Indemnification Claim to the Indemnitor in accordance with the

provisions of Section 10.3. If the Litigation Conditions are satisfied, then the Indemnitor shall have the right to assume and control the defense of the Claim, at its own expense with counsel selected by it and reasonably acceptable to the Indemnitee, by delivering written notice of its assumption of such defense to the Indemnitee within [***] of its receipt of notice of such Claim from the Indemnitor (but the Indemnitor shall in any event have the right to assume and control the defense of a Claim that initially sought injunctive relief (including a declaratory judgment) from the Indemnitee when the only remaining dispute in such matter is the determination of non-injunctive relief or when the only remaining relief sought by the Third Party in such matter is non-injunctive relief, whichever is first); provided, however, that the Indemnitee shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the Indemnitor, if (a) representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflict of interests between such Indemnitee and Indemnitor, (b) the Indemnitor has failed within a reasonable time to retain counsel, (c) the Indemnitee shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnitor, or (d) at any time the Litigation Conditions are not satisfied with respect to such Claim. If the Indemnitor assumes and controls the defense of such Claim, the Indemnitor shall keep the Indemnitee reasonably apprised of the status of the Claim and the Indemnitee shall be entitled to otherwise monitor such Claim at its sole cost and expense. If the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee or if the Indemnitor does not assume the defense of the Claim as described in this Section 10.4, the Indemnitee shall be permitted to assume and control the defense of such Claim (but shall have no obligation to do so) and in such event shall be entitled to settle or compromise the Indemnification Claims in its sole and reasonable discretion, provided that if the Indemnitee is entitled to assume the defense of the Claim pursuant to this Section 10.4 solely because the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee, then the Indemnitee shall not settle or compromise such Indemnification Claims in any manner that involves the payment of monetary damages or has an adverse effect on the Indemnitor’s rights or interests (including any rights under this Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this Agreement or a Development & Commercialization Agreement) without the prior written consent of the Indemnitor, which consent the Indemnitor shall not unreasonably withhold, condition or delay. If the Indemnitor has assumed and controls the defense of the Claim in accordance with this Section 10.4, (i) the Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld, conditioned or delayed and (ii) the Indemnitor shall not settle or compromise the Indemnification Claim in any manner that would result in the payment of amounts by the Indemnitee, impose any other obligation on the Indemnitee or otherwise have an adverse effect on the Indemnitee’s rights or interests (including any rights under this Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this Agreement or a Development & Commercialization Agreement), without the prior written consent of the Indemnitee. In each case, the Party that is not controlling the defense of any Claim shall reasonably cooperate with the Party that is controlling the defense of such Claim, at the non-controlling Party’s expense and shall make available to the controlling Party all pertinent information under the control of the non-controlling Party, which information shall be subject to Article 8. Each Party shall use commercially reasonable efforts to avoid production of

Confidential Information of the other Party (consistent with applicable Law and rules of procedure), and to cause all communications among employees, counsel and other representatives of such Party to be made so as to preserve any applicable attorney-client or work-product privileges.

10.5 Indemnification Following Exercise of the Option. The Development & Commercialization Agreements provide separately for each Party’s indemnification obligations with respect to each Target or Biologic Specifically Directed to a Target, or products constituting, incorporating, comprising or containing such Biologic, that is the subject of such agreement following exercise of the Option for such Program.

10.6 Insurance. Each Party shall maintain, at its cost, a program of insurance and/or self-insurance against liability and other risks associated with its activities and obligations under this Agreement, including as applicable its Clinical Trials, the Commercialization of any Collaboration Candidate, and its indemnification obligations hereunder, in such amounts, subject to such deductibles and on such terms as are customary for such Party for the activities to be conducted by it under this Agreement.

ARTICLE 11.
TERM AND TERMINATION

11.1 Term; Expiration. Unless earlier terminated in accordance with this Article 11, the term of this Agreement (the “Term”) shall commence as of the Effective Date and remain in force until the later of (a) the expiration of the last-to-expire of the following (i) all Option Terms; and (ii) the Research Term; and (b) if one or more Options is exercised, the termination or expiration of the last to expire Development & Commercialization Agreement executed with respect to any Program hereunder.

11.2 Termination for Breach.

11.2.1 Material Breach. Subject to the other terms of this Agreement, this Agreement and the rights granted herein may be terminated by either Party (a) on a Program-by-Program basis prior to Celgene’s exercise of its Option for such Program, for the Material Breach by the other Party of this Agreement with respect to such Program, or (b) on a Program-by-Program basis after Celgene’s exercise of its Option for such Program, if a Development & Commercialization Agreement for such Program is terminated for Material Breach by a Party; provided in each of (a) or (b) that the breaching Party has not cured such breach within [***] after the date of written notice to the breaching Party of such breach (or [***] in the case of a breach as a result of non-payment of any amounts due under this Agreement or a Development & Commercialization Agreement, as applicable) (the “Cure Period”), which notice shall describe such breach in reasonable detail and shall state the non-breaching Party’s intention to terminate this Agreement with respect to a given Program, pursuant to this Section 11.2.1 with respect to such Program. For clarity, but subject to Section 11.2.2, the Cure Period for any allegation made in good faith as to a Material Breach under this Agreement with respect to a given Program for events described in Sections 11.2.1(a) or (b) will run from the date that written notice was first provided to the breaching Party by the non-breaching Party. Any such termination of this Agreement with respect to a given Program under this Section 11.2.1 shall become effective at the end of the Cure Period, unless the breaching Party has cured any such breach or default prior to the expiration of such Cure Period, or, if such breach is not susceptible to cure within the Cure Period, then, the non-breaching Party’s right of termination shall be suspended only if and for so long as the breaching Party has provided to the non-breaching Party a written plan that is reasonably calculated to effect a cure and such plan is acceptable to the non-breaching Party, and the breaching Party commits to and carries out such plan as provided to the non-breaching Party. For the avoidance of doubt, termination of any particular Program(s) pursuant to this Section 11.2.1 shall not terminate (i) this Agreement with respect to any other Program(s) or (ii) any Development & Commercialization Agreement for any other Program. The Parties understand and agree that the totality of this Agreement with respect to a given Program, and the totality of the circumstances with respect to this Agreement with respect to a given Program, will be taken into account and assessed as a whole for purposes of determining whether a breach is material under this Agreement with respect to a given Program.

11.2.2 Disagreement as to Material Breach. If the Parties reasonably and in good faith disagree as to whether there has been a Material Breach pursuant to either Section 11.2.1(a) or 11.2.1(b), then subject to Section 12.7: (a) the Party that disputes that there has been a Material Breach may contest the allegation by referring such matter, within [***] following such notice of alleged Material Breach for resolution to the Executive Officers, who shall meet promptly to discuss the matter, and determine, within [***] following referral of such matter, whether or not a Material Breach has occurred pursuant to Section 11.2.1(a) or 11.2.1(b), as applicable; (b) the relevant Cure Period with respect thereto will be tolled from the date the breaching Party notifies the non-breaching Party of such dispute and through the resolution of such dispute in accordance with the applicable provisions of this Agreement (provided, that if such dispute relates to payment, the Cure Period will only apply with respect to payment of disputed amounts, and not with respect to undisputed amounts), (c) it is understood and agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder) and (d) if it is finally and conclusively determined that the breaching Party committed

such Material Breach, then the breaching Party shall have the right to cure such Material Breach after such determination within the Cure Period.

11.2.3 If the Executive Officers are unable to resolve a dispute within such [***] period after it is referred to them, the matter will be resolved as provided in Section 12.7.

11.3 Voluntary Termination. Celgene may terminate this Agreement in its entirety or with respect to one or more Programs upon [***] prior written notice to Jounce hereunder at any time (it being understood and agreed that Celgene shall be entitled to terminate upon [***] written notice at any time it reasonably determines that such termination is necessary to comply with any Antitrust Law), except that Celgene shall not have the right to terminate any Program under this Section 11.3 for which Celgene has exercised its Option. For the avoidance of doubt, any such termination of any particular Program(s) pursuant to this Section 11.3 shall not terminate any other Program(s), and such terminated Program shall be deemed a “Lapsed Program”.

In connection therewith, the provisions of Section 7.1.5 shall apply.

(b) all Development & Commercialization Agreements previously entered into by the Parties for Programs for which Celgene exercised its Option shall continue in full force, in accordance with the terms and conditions of such Development & Commercialization Agreements; and

(c) Jounce shall promptly return to Celgene all data, Confidential Information and materials transferred by Celgene to Jounce under this Agreement, consistent with Article 8.

11.6 Surviving Provisions.

11.6.1 Accrued Rights; Remedies. Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination, relinquishment or expiration, including the payment obligations under Article 6 hereof, and any and all damages or remedies (whether in law or in equity) arising from any breach hereunder. Such termination, relinquishment or expiration shall not relieve any Party from obligations which are expressly indicated to survive termination of this Agreement. Except as otherwise expressly set forth in this Agreement, the

termination provisions of this Article 11 are in addition to any other relief and remedies available to either Party under this Agreement and at Law.

11.6.2 Survival. Notwithstanding any provision herein to the contrary, any rights or obligations otherwise accrued hereunder (including any accrued payment obligations) shall survive the expiration or termination of this Agreement. Further, the rights and obligations of the Parties set forth in the following Sections and Articles shall survive the expiration or termination of this Agreement, in addition to those other terms and conditions that are expressly stated to survive termination or expiration of this Agreement:

(b) with respect to any Programs that are the subject of executed Development & Commercialization Agreements remaining in effect, Sections 2.3, 2.4, 2.5, 2.6, 3.2, 4, 6.9, 7 and 10 (to the extent applicable to claims arising after such expiration or termination to the extent a Party retains a license from the other Party to Develop, Manufacture or Commercialize Products, Collaboration Candidates, or Development Candidates thereafter), and Exhibit G;

provided that such survival shall be limited to any specific time periods set forth in such Articles and Sections, if any. For the avoidance of doubt, in the event notice of termination of this Agreement is given prior to the achievement of any milestone set forth in the applicable Development & Commercialization Agreement, Celgene shall not be obligated to make any milestone payment to Jounce with respect to any milestone achieved following the notice of such termination.

11.6.3 Relationship to Other Agreements.

ARTICLE 12.
MISCELLANEOUS

12.1 Severability. If any one or more of the terms or provisions of this Agreement is held by a court of competent jurisdiction or arbitrator to be void, invalid or unenforceable in any situation in any jurisdiction, such holding shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the invalid, void or unenforceable term or provision in any other situation or in any other jurisdiction and the term or provision shall be considered severed from this Agreement, unless the invalid or unenforceable term or provision is of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid or

unenforceable term or provision. If the final judgment of such court or arbitrator declares that any term or provision hereof is invalid, void or unenforceable, the Parties agree to (a) reduce the scope, duration, area or applicability of the term or provision or to delete specific words or phrases to the minimum extent necessary to cause such term or provision as so reduced or amended to be enforceable, and (b) make a good faith effort to replace any invalid or unenforceable term or provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

12.2 Notices. Any notice required or permitted to be given by this Agreement shall be in writing and in English and shall be (a) delivered by hand or by overnight courier with tracking capabilities, (b) mailed postage prepaid by first class, registered, or certified mail, or (c) delivered by facsimile followed by delivery via either of the methods set forth in Sections 12.2(a) and (b), in each case, addressed as set forth below unless changed by notice so given:

A Party may add, delete, or change the person or address to which notices should be sent at any time upon written notice delivered to the other Parties in accordance with this Section 12.2.

12.3 Force Majeure. Except for the payment of money, no Party shall be liable for delay or failure in the performance of any of its obligations hereunder if such delay or failure is due to a cause beyond the reasonable control of a Party, including acts of God, fires, earthquakes, acts of war, terrorism, or civil unrest, or hurricane or other inclement weather (“Force Majeure”); provided, however, that the affected Party promptly notifies the other Party and further provided that the affected Party shall use its commercially reasonable efforts to avoid or remove such causes of non-performance and to mitigate the effect of such occurrence, and shall continue performance with the utmost dispatch whenever such causes are removed. When such

circumstances arise, the Parties shall negotiate in good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order to arrive at an equitable solution.

12.4 Assignment.

12.4.1 Generally. This Agreement may not be assigned by any Party, nor may any Party delegate its obligations or otherwise transfer licenses or other rights created by this Agreement, except as expressly permitted hereunder without the prior written consent of the other Party, which consent will not be unreasonably withheld, delayed or conditioned.

12.4.2 Celgene. Notwithstanding the limitations in Section 12.4.1, Celgene Corp. and Celgene RIVOT may assign this Agreement, or any rights or obligations hereunder in whole or in part, to (a) one or more Affiliates or (b) its successor in interest in connection with the merger, consolidation, or sale of all or substantially all of its assets or that portion of its business pertaining to the subject matter of this Agreement.

12.4.3 Jounce. Notwithstanding the limitations in Section 12.4.1, Jounce may assign this Agreement, or any rights or obligations hereunder in whole or in part, to (a) one or more Affiliates solely as provided in this Section 12.4.3 or (b) its successor in connection with the merger, consolidation, or sale of all or substantially all of its assets or that portion of its business pertaining to the subject matter of this Agreement; provided however that, except in the case where Jounce [***], (i) Jounce provides Celgene [***] advance written notice of any such assignment(s), (ii) prior to such assignment(s), Jounce agrees in a written agreement delivered to Celgene (and upon which Celgene may rely) to remain fully liable for the performance of its obligations under this Agreement by its assignee(s), and (iii) prior to such assignment(s), the assignee(s) agree in a written agreement delivered to Celgene (and upon which Celgene may rely) to assume performance of all such assigned obligations, (iv) in the case of any assignment(s) by Jounce, [***], and (v) all of the matters referred to in clauses (i), (ii), (iii) and (iv), as applicable, will be set forth in documentation [***] prior to any such assignment(s) [***] and in all cases will provide [***].

12.5 Waivers and Modifications. The failure of any Party to insist on the performance of any obligation hereunder shall not be deemed to be a waiver of such obligation. Waiver of any breach of any provision hereof shall not be deemed to be a waiver of any other breach of such provision or any other provision on such occasion or any succeeding occasion. No waiver, modification, release, or amendment of any obligation under or provision of this Agreement shall be valid or effective unless in writing and signed by the Parties against whom enforcement is sought.

12.6 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,

PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

12.7 Choice of Law; Jurisdiction; Venue. This Agreement shall be governed by, enforced, and shall be construed in accordance with the Laws of the State of New York without regard to any conflicts of law provision that would result in the application of the Laws of any State other than the State of New York and excluding the United Nations Convention on Contracts for the International Sales of Goods; provided however that with respect to matters involving the enforcement, validity or scope of intellectual property rights, the Laws of the applicable country shall apply. Each Party hereby irrevocably and unconditionally (a) consents to submit to the non-exclusive jurisdiction of the state and federal courts located in New York, New York, for any actions, suits or proceedings arising out of or relating to this Agreement and the transactions contemplated hereby and (b) waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the state and federal courts of New York, New York, and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

12.8 Relationship of the Parties. Jounce and Celgene are independent contractors under this Agreement. Nothing contained herein is intended or is to be construed so as to constitute (a) Jounce as partner, agent, or joint venturer of Celgene or (b) Celgene as a partner, agent or joint venturer of Jounce. Neither Jounce nor Celgene shall have any express or implied right or authority to assume or create any obligations on behalf of or in the name of Celgene or Jounce, respectively, or to bind Celgene or Jounce, respectively, to any contract, agreement, or undertaking with any Third Party. There are no express or implied third party beneficiaries hereunder.

12.9 Entire Agreement. This Agreement, together with the attached Exhibits (including the form of PD-1 License Agreement, each form of Co-Development and Co-Commercialization Agreement, and the Equity Purchase Agreement) and Schedules, contains the entire agreement by the Parties with respect to the subject matter hereof and supersedes any prior express or implied agreements, understandings and representations, either oral or written, which may have related to the subject matter hereof in any way, including the Existing Confidentiality Agreement (as set forth in Section 8.8) and any and all term sheets relating to the transactions contemplated by this Agreement and exchanged between the Parties prior to the Effective Date; it being understood and agreed that this Agreement shall not in any way modify or supersede that certain Confidentiality Agreement, dated June 24, 2016, between Jounce and Celgene Corp.

12.10 Counterparts. This Agreement may be executed in counterparts with the same effect as if both Parties had signed the same document. All such counterparts shall be deemed an original, shall be construed together, and shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a fax machine or by .pdf, .tif, .gif, .jpeg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party hereto shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a defense to the formation of a contract, and each Party forever waives any such defense, except to the extent that such defense relates to lack of authenticity.

12.11 Equitable Relief. Notwithstanding anything to the contrary herein, the Parties shall be entitled to seek equitable relief, including injunction and specific performance, as a remedy for any breach of this Agreement. Such remedies shall not be deemed to be the exclusive remedies for a breach of this Agreement but shall be in addition to all other remedies available at law or equity. The Parties further agree not to raise as a defense or objection to the request or granting of such relief that any breach of this Agreement is or would be compensable by an award of money damages.

12.12 Interpretation.

12.12.1 Generally. This Agreement has been diligently reviewed by and negotiated by and among the Parties, and in such negotiations each of them has been represented by competent counsel, and the final agreement contained herein, including the language whereby it has been expressed, represents the joint efforts of the Parties and their counsel. Accordingly, in interpreting this Agreement or any provision hereof, no presumption shall apply against any Party as being responsible for the wording or drafting of this Agreement or any such provision, and ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision.

12.12.2 Definitions; Pronouns. The definitions of the terms herein shall apply equally to the singular and plural forms of the terms defined and where a word or phrase is defined herein, each of its other grammatical forms shall have a corresponding meaning. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine, and neuter forms. The word “will” shall be construed to have the same meaning and effect as the word “shall.” The word “any” shall mean “any and all” unless otherwise clearly indicated by context. The word “including,” “includes,” “include,” “for example,” and “e.g.” will be deemed to be followed by the words “without limitation.” The word “or” is disjunctive but not necessarily exclusive. The words “hereof,” “herein” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement.

12.12.3 Subsequent Events. Unless the context requires otherwise, (i) any definition of or reference to any agreement, instrument, or other document herein shall be construed as referring to such agreement, instrument, or other document as from time to time amended, supplemented, or otherwise modified (subject to any restrictions on such amendments,

supplements, or modifications set forth herein or therein), (ii) any reference to any Laws herein shall be construed as referring to such Laws as from time to time enacted, repealed, or amended, (iii) any reference herein to any Person shall be construed to include the Person’s successors and assigns, and (iv) all references herein to Articles, Sections, Schedules or Exhibits, unless otherwise specifically provided, shall be construed to refer to Articles, Sections, Schedules and Exhibits of this Agreement.

12.12.4 Headings. Headings, captions and the table of contents are for convenience only and are not to be used in the interpretation of this Agreement.

12.12.5 Prior Drafts. No prior draft of this Agreement nor any course of performance or course of dealing shall be used in the interpretation or construction of this Agreement.

12.12.6 Independent Significance. Although the same or similar subject matters may be addressed in different provisions of this Agreement, the Parties intend that, except as reasonably apparent on the face of the Agreement or as expressly provided in this Agreement, each such provision shall be read separately, be given independent significance and not be construed as limiting any other provision of this Agreement (whether or not more general or more specific in scope, substance or content).

12.13 Further Assurances. Each Party shall execute, acknowledge and deliver such further instruments, and do all such other acts, as may be necessary or appropriate in order to carry out the expressly stated purposes and the clear intent of this Agreement.

12.14 Celgene Parties. The Parties hereby acknowledge and agree that (a) Celgene Corp. is the party to this Agreement with respect to all rights and obligations under this Agreement in the United States; and (b) Celgene RIVOT is the party to this Agreement with respect to all rights and obligations under this Agreement outside of the United States.

Each Party will cause each of its

sales representatives assigned to promote the Co-Co Product to attend and complete the training program developed as provided above for the Co-Co Product to assure a consistent, focused promotional strategy and message as and to the extent consistent with applicable Law.

(b) Sales Representatives; Detailing. The following provisions shall apply to the activities of sales representatives with respect to Commercialization of Co-Co Products:

(i) Each Party will be solely responsible for recruiting, hiring and maintaining its sales force of sales representatives for promotion of the Co-Co Product in accordance with its standard procedures, the requirements of this Celgene Lead Co-Co Agreement and the minimum qualifications set forth on Schedule 3.1.5(b). Each Party will be responsible for the activities of its sales representatives, including compliance by its sales representatives with training and detailing requirements. In particular, each Party will provide its sales representatives assigned to promote the Co-Co Product in the U.S. with the level of oversight, management, direction and sales support with respect to the promotion of Co-Co Product necessary to effectively and efficiently promote the Co-Co Product in accordance with the terms of this Celgene Lead Co-Co Agreement and applicable Law. Each Party agrees that none of its sales representatives involved in the promotion of the Co-Co Product will have any legal or regulatory disqualifications, bars or sanctions. If Celgene raises any reasonable concern with Jounce regarding the performance or fitness of any of Jounce’s sales representatives, Jounce will address such concerns in a reasonable manner.

(ii) Notwithstanding the foregoing, Jounce will not have the right to use any Third Party contract sales force to fulfil its obligations under this Celgene Lead Co-Co Agreement, except with the prior written consent of Celgene not to be unreasonably withheld or delayed (provided that Celgene may withhold or revoke its consent, with respect to all Co-Co Products, for any reason during the [***] following First Co-Co Sale in the United States upon reasonable written notice to Jounce).

(iv) If Jounce does not provide in the United States at any particular time, for any reason, the number of sales representatives

specified in the U.S. Commercialization Plan to be provided for the United States, then Celgene will have the right to make up such shortfall using its sales representatives until such time as Jounce is able to provide its agreed upon number of sales representatives and for a period of [***] days thereafter, and, for clarity, all costs incurred by Celgene related to Celgene’s making up such shortfall shall be included in the calculation of Operating Profits or Losses.

(v) The calculation of costs of engaging sales representatives in the United States for purposes of calculating Operating Profits or Losses shall be based on the FTE Rate, and such FTE Rate shall be used by both Parties for promotion of Co-Co Product in the United States.

(c) Promotional Materials. Each Party’s sales representatives assigned to promote the Co-Co Product in the United States will utilize only promotional materials that have been approved by Celgene. All detailing activities conducted by each Party’s sales representatives will be consistent in all material respects with the promotional materials so approved. Each Party will train and instruct their respective sales representatives to make only those statements and claims regarding the Co-Co Product, including as to efficacy and safety, that are consistent with the Co-Co Product labeling and accompanying inserts and the approved promotional materials. For clarity, all marketing and promotional materials used in the United States must be approved by Celgene prior to use.

(d) Medical Affairs; Information. For Co-Co Products in the United States, the Parties will discuss the implementation of medical and scientific affairs and programs, including for professional symposia and other educational activities, and medical affairs studies based upon approved protocols, medical information support and medical communications and publishing activities, and the allocation of each Party to such activities in the United States, provided Jounce shall have the final decision-making authority to the conduct of such activities in the United States. The Parties acknowledge that in the United States each Party may receive requests for medical information concerning the Co-Co Product from members of the medical professions and consumers. Celgene will have the exclusive right to respond to questions and requests for information about Co-Co Product received from Persons in the Territory that warrant a response beyond the understanding of the sales representatives or that are beyond the scope of the Co-Co Product labels and inserts (each such request, an “Information Request”) and that are solely applicable to Co-Co Product for U.S. Administration. Any Information Request that is applicable to Co-Co Product throughout the Territory shall be referred to the JCC.

(e) Market Access Activities. Celgene, as the Commercialization Lead Party, will have sole authority, in the Territory, in consultation with the JCC, to develop plans for market access activities. For Co-Co Products in the United States, each Party shall have the right to participate in the foregoing activities in accordance with the U.S. Commercialization Plan. For

clarity, the costs related to such market access activities shall be included as an Allowable Expense in the calculation of Operating Profits or Losses.

(f) Reporting. Each Party will provide the JCC with a report, as soon as practicable but in no event later than [***] following the end of each Calendar Quarter commencing as of the date upon which the first Co-Co Product has received Regulatory Approval in the Territory, or at such other time as the JCC deems appropriate, and continuing thereafter for each Calendar Quarter for the remainder of the Celgene Co-Co Term for such Co-Co Product, setting forth the number of details made by its sales representatives of Co-Co Product during such Calendar Quarter. Costs and expenses for sales representatives for U.S. Administration will be charged to the Profit & Loss Share on an FTE Rate basis consistent with the U.S. Commercialization Budget.

If and at such time as the JCC deems appropriate, the JCC shall discuss in good faith any branding and/or co-branding of the Co-Co Products to be used in connection with the Commercialization of Co-Co Products both in the United States and the ROW Territory, and the Parties will enter into appropriate trademark licensing agreements to achieve the foregoing. For the avoidance of doubt, nothing in this Celgene Lead Co-Co Agreement shall be construed to grant either Party any rights in or to any of the other Party’s trademarks, trade names, logos, or other marks, including use thereof, absent a separate trademark licensing agreement entered into in accordance with this Section 3.2.2.

3.2.3 Commercialization Reports. Celgene will, with Jounce’s cooperation

with respect to its activities under the U.S. Commercialization Plan, provide the JCC with a report, as soon as practicable but in no event later than [***] days following the end of each Calendar Quarter commencing as of and continuing after the Calendar Quarter in which the first Co-Co Product has received Regulatory Approval in the United States setting forth a summary written progress report on the status of its Commercialization Activities with respect to Co-Co Products and Co-Co Diagnostic Products, including the number of details made by any sales representatives of Co-Co Product in the United States during such Calendar Quarter (a “U.S. Commercialization Report”), as well as Celgene’s plans with respect to Commercialization of Co-Co Products and Co-Co Diagnostic Products during the following [***] period.

4.3.3 Membership. The JCC shall be comprised of three (3) representatives (or such other number of representatives as the Parties may mutually agree) from each of Celgene and Jounce. Each representative of a Party shall have sufficient seniority and expertise in the commercialization of pharmaceuticals to participate on the JCC. Jounce shall have the right to designate the chairperson of the JCC. Each Party may replace any or all of its representatives on the JCC at any time upon written notice to the other Party in accordance with Section 12.2 of the Master Collaboration Agreement. Each Party may, subject to the other Party’s prior approval, invite non-member representatives of such Party and any Third Party to attend meetings of the JCC as non-voting participants; provided, that any such representative or Third Party is bound by obligations of confidentiality, non-disclosure and non-use consistent with those set forth herein prior to attending such meeting and provided, further, that such Third Party shall not have any voting or decision-making authority on the JCC.

Any payments or portions thereof due hereunder that are not paid on the date such payments are due under this Celgene Lead Co-Co Agreement shall bear interest at an annual rate equal to the lesser of: (a) [***] above the prime rate as published by Citibank, N.A., New York, New York, or any successor thereto, at 12:01 a.m. on the first day of each Calendar Quarter in which such payments are overdue or (b) the maximum rate permitted by applicable Law; in each case calculated on the number of days such payment is delinquent, compounded monthly.

5.7.3 Tax Withholding.

(a) Each Party shall be entitled to deduct and withhold from any amounts payable under this Celgene Lead Co-Co Agreement (or allocable to another Party pursuant to Section 1.6 of Exhibit G) such taxes as are required to be deducted or withheld therefrom under any provision of applicable Law. The Party that is required to make such withholding (the “Paying Party”) will: (i) deduct those taxes from such payment, (ii) timely remit the taxes to the proper taxing authority, and (iii) send evidence of the obligation together with proof of tax payment to the recipient Party (the “Payee Party”) on a timely basis following that tax payment; provided, however, that before making any such deduction or withholding, the Paying Party shall give the Payee Party notice of the intention to make such deduction or withholding (and such notice, which shall set forth in reasonable detail the authority, basis and method of calculation for the proposed deduction or withholding, shall be given at least a reasonable period of time before such deduction or withholding is required, in order for such Payee Party to obtain

reduction of or relief from such deduction or withholding). Each Party agrees to assist and cooperate with the other Parties in claiming refunds or exemptions from such deductions or withholdings under any relevant agreement or treaty or other applicable Law which is in effect to ensure that any amounts required to be withheld pursuant to this Section 5.7.3(a) are reduced in amount to the fullest extent permitted by applicable Laws. In addition, the Parties shall cooperate in accordance with applicable Laws to minimize [***].

(b) Notwithstanding the foregoing, and subject to Section 5.7.3(c) of this Celgene Lead Co-Co Agreement, if (i) a Paying Party (or its assignee pursuant to Section 9.4) redomiciles or assigns its rights or obligations under this Agreement pursuant to Section 9.4, (ii) as a result of such redomiciliation or assignment, such Party (or its assignee pursuant to Section 9.4) is required by applicable Law to withhold taxes, or if such redomiciliation or assignment results in the imposition of Indirect Taxes that were not otherwise applicable, from or in respect of any amount payable under this Celgene Lead Co-Co Agreement (or any other agreement entered into pursuant to this Celgene Lead Co-Co Agreement), and (iii) such withholding taxes or Indirect Taxes exceed the amount of withholding taxes or Indirect Taxes that would have been applicable if such redomiciliation or assignment had not occurred, then any such amount payable shall be increased to take into account such increased withholding taxes or Indirect Taxes as may be necessary so that, after making all required withholdings (including withholdings on the withheld amounts) and/or paying such Indirect Taxes, as the case may be, the Payee Party (or its assignee pursuant to Section 9.4) receives an amount equal to the sum it would have received had such redomiciliation or assignment not occurred; provided, however, that the Paying Party will have no obligation to pay any additional amount under the immediately preceding clause to the extent that such withholding taxes or such Indirect Taxes would not be imposed but for the failure by the Payee Party to comply with the requirements of Section 5.7.3(c). The additional amounts payable pursuant to this Section 5.7.3(b) shall be reduced by the amount any foreign tax credit, tax refund or similar item available to the Payee Party in respect or as a result of withholding taxes or Indirect Taxes for which additional amounts have been paid pursuant to this Section 5.7.3(b), as mutually determined by the Parties cooperating in good faith.

(c) Tax Documentation. The Parties have each provided to the other Parties a properly completed and duly executed IRS Form W-9 or applicable Form W-8. Each Party and any other recipient of payments under this Celgene Lead Co-Co Agreement shall provide to the other Party, at the time or times reasonably requested by such other Party or as required by applicable Law, such properly completed and duly executed documentation as will permit payments made under this Celgene Lead Co-Co Agreement to be made without, or at a reduced rate of, withholding for taxes, and the applicable payment shall be made without (or at a reduced rate of) withholding to the extent permitted by such documentation, as reasonably determined by the Paying Party.

5.8 Records Retention by Celgene; Review by Jounce.

5.8.1 Royalty Records. With respect to payments to be made under Sections 5.1 through 5.4, inclusive, Celgene agrees to keep, and to require its Affiliates and Sublicensees to keep, for at least [***] from the end of the Calendar Year to which they pertain, complete and accurate records of transfer and sales by Celgene or its Affiliates or Sublicensees, as the case

may be, of each Co-Co Product, in sufficient detail to allow the accuracy of the payments made thereunder to be confirmed.

5.8.2 Review. Subject to the other terms of this Section 5.8.2, at the request of Jounce, which shall not be made more frequently than [***] during the Co-Co Term, upon at least [***] prior written notice from Jounce, and at the expense of Jounce, Celgene shall permit an independent, nationally-recognized certified public accountant selected by Jounce and reasonably acceptable to Celgene to inspect (during regular business hours) the relevant records required to be maintained by Celgene under Section 5.8.1. In every case the accountant must have previously entered into a confidentiality agreement with both Parties substantially similar to the provisions of Article 8 of the Master Collaboration Agreement and limiting the disclosure and use of such information by such accountant to authorized representatives of the Parties and the purposes germane to Section 5.8.1. Results of any such review shall be binding on both Parties absent manifest error. Jounce shall treat the results of any such accountant’s review of Celgene’s records as Confidential Information of Celgene subject to the terms of Article 8 of the Master Collaboration Agreement. If any review reveals a deficiency or overpayment in the calculation and/or payment of royalties by Celgene, then (a) Celgene or Jounce shall promptly pay the other Party the amount remaining to be paid, and (b) if such underpayment is by [***] or more in any Calendar Year, Celgene shall, within [***] of invoice therefor, pay the reasonable Out-of-Pocket Costs incurred by Jounce in connection with the review.

(a) Celgene ROW Initial Enforcement. As between the Parties, and subject to Section 6.7, Celgene shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any Competitive Infringement in the ROW Territory of (A) any Celgene Co-Co Collaboration Patent that is exclusively licensed to Celgene under this Celgene Lead Co-Co Agreement and that solely Covers Co-Co Products or the Co-Co Candidate (such Patents, the “Celgene Co-Co Product Patents”) and (B) any Celgene Patent, in each case by counsel of its own choice, in Celgene’s own name and under Celgene’s direction and control, provided that Celgene shall keep Jounce, through the JSC and/or Patent Committee, reasonably informed as to the status of, and all material developments in such action, including considering in good faith, the input of Jounce regarding the strategy and handling of such enforcement activities.

(b) Celgene U.S. Initial Enforcement. As between the Parties, and subject to Section 6.7, Celgene shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any Competitive Infringement in the United States of (A) any Celgene Co-Co Product Patent, and (B) any Celgene Patent, in each case by counsel of its own choice, in Celgene’s own name and under Celgene’s direction and control, provided that Celgene shall keep Jounce, through the JSC and/or Patent Committee, reasonably informed as to the status of, and all material developments in such action, including considering in good faith, the input of Jounce regarding the strategy and handling of such enforcement activities. For clarity, Celgene shall have final decision-making authority as to representations made in any proceedings under this Section 6.5 with respect to any Celgene Independent Products.

(c) Timing. Celgene, as the Party having the first right to enforce a Patent pursuant to Sections 6.5.2(a) and 6.5.2(b), will have a period of [***] after its delivery of notice and evidence pursuant to Section 6.5.1 or receipt of written notice from a Third Party that reasonably evidences any action or proceeding with respect to any Co-Co Competitive

Infringement described in Section 6.5.2(a), as applicable (such action or proceeding a “Co-Co Enforcement Proceeding”), to elect to so enforce such Celgene Co-Co Collaboration Patent or Celgene Patent, as applicable, in the applicable jurisdiction (or to settle or otherwise secure the abatement of such Co-Co Competitive Infringement), provided however, that such period will be (i) more than [***] to the extent applicable Law prevents earlier enforcement of such Celgene Co-Co Collaboration Patent or Celgene Patent, as applicable, and provided further that if such period is extended because applicable Law prevents earlier enforcement, Celgene shall have until the date that is [***] following the date upon which applicable Law first permits such Co-Co Enforcement Proceeding, and (ii) less than [***] to the extent that a delay in bringing such Co-Co Enforcement Proceeding against such alleged Third Party infringer would limit or compromise the remedies (including monetary relief, and stay of regulatory approval) available against such alleged Third Party infringer. In the event Celgene does not so elect to enforce or settle or otherwise secure the abatement of such Co-Co Competitive Infringement before the first to occur of (A) the expiration of the applicable period of time set forth in above, or (B) [***] before the expiration of any time period under applicable Law, that would, if a Co-Co Enforcement Proceeding was not filed within such time period, limit or compromise the remedies available from such Co-Co Enforcement Proceeding, Celgene will so notify Jounce in writing and in the case where such other Party then desires to commence a suit or take action to enforce the applicable Celgene Co-Co Collaboration Patent or Celgene Patent with respect to such Co-Co Competitive Infringement in the applicable jurisdiction, Jounce will, subject to Section 6.5.2(e), thereafter have the right to commence such a suit or take such action to enforce the applicable Celgene Co-Co Collaboration Patent or Celgene Patent, as applicable (such action, a “Co-Co Step-In Proceeding”), at such other Party’s expense. Notwithstanding anything in this Section 6.5 to the contrary, Celgene shall have final decision-making authority as to representations made in any proceedings under this Section 6.5 with respect to any Celgene Independent Products.

(d) Right to Participate; Joinder. The non-enforcing Party in relation to any enforcement action or proceeding set forth in Sections 6.5.2(a) through 6.5.2(b) will have the right, at its own expense and by counsel of its choice, to be represented in any such action or proceeding. In the case of any Co-Co Enforcement Proceeding or Co-Co Step-In Proceeding, at the enforcing Party’s written request, and at the enforcing Party’s expense (subject to Section 6.5.4), the other Party shall join any such action or proceeding as a party and will use Commercially Reasonable Efforts to cause any Third Party as necessary to join such action or proceeding as a party if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable Law to pursue such action or proceeding, or if the JSC (with respect to enforcement activities relating to Co-Co Product for U.S. Administration) determines that such joinder is necessary or desirable. All time periods set forth in this Section 6.5.2 shall be subject to applicable Law, which may prevent earlier enforcement.

Each Party bringing any such action or proceeding in accordance with this Section 6.5 shall have an obligation to consult with the other Party and will take comments of such other Party into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any Celgene Co-Co Collaboration Patent and Celgene Patent that is the subject of such proceeding.

(f) Agreement to Enforce. Notwithstanding anything to the contrary in this Section 6.5, if either Party has a reasonable, good faith concern that the other Party’s exercise of its backup enforcement or defense rights with respect to any Patent as set forth in Section 6.5.2(a) and 6.5.2(b) would be detrimental to the overall patent protection of the Co-Co Products or related Co-Co Diagnostic Products, then such other Party shall not be permitted to enforce or defend such Patent without the prior consent of the objecting Party.

(g) Settlement. Notwithstanding anything to the contrary in this Section 6.5, a settlement or consent judgment or other voluntary final disposition of a suit under this Section 6.5: (i) with respect to enforcement in the ROW Territory, may be entered into without the consent of the Party not bringing suit, and (ii) with respect to enforcement in the U.S., may only be entered into with the approval of the JSC; provided, however, that in any event, any such settlement, consent judgment or other disposition of any action or proceeding by a Party under this Article 6 shall not, without the consent of the Party not bringing suit, (a) impose any liability or obligation on the Party not bringing suit, (b) include the grant of any license, covenant or other rights to any Third Party that would conflict with or reduce the scope of the subject matter included under the licenses granted to the Party not bringing suit under this Celgene Lead Co-Co Agreement, (c) conflict with or reduce the scope of the subject matter claimed in any Patent owned by the Party not bringing suit, or (d) adversely affect the interest of the Party not bringing suit in any material respect, provided that such consent shall not be unreasonably withheld, conditioned or delayed.

(i) Recoveries. Any damages or other monetary awards recovered in any action, suit or proceeding brought under this Section 6.5 shall be shared as follows:

(i) Initial Allocation. Such damages or other sums recovered shall first be applied to reimburse each Party for all of its Out-of-Pocket Costs expenses incurred by

each Party directly in connection with such action (including, for this purpose, a reasonable allocation of expenses of outside counsel), and if such recovery is insufficient to cover all such costs and expenses of both Parties, it shall be shared in proportion to the total of such costs and expenses incurred by each Party; and

(ii) Remaining Proceeds. Any remaining proceeds in case of suits with respect to a Co-Co Enforcement Proceeding or a Co-Co Step-In Proceeding relating to any Co-Co Product or related Co-Co Diagnostic Product under this Section 6.5, shall, (A) with respect to such suits in the ROW Territory, be allocated between the Parties such that the Party bringing suit under this Section 6.5 retains [***] and the other Party retains [***] of such amount, and (B) with respect to suits in the U.S., shall be shared by the Parties in accordance with the Profit & Loss Share.

(j) Opt-Out by Jounce.

If the Parties are unable to reach mutual agreement, Celgene shall have the right to make the final decision in the Territory.

6.7 Third Party Licenses. If, at any time during the Celgene Co-Co Term, either Party reasonably determines that any Third Party intellectual property rights may be necessary for the Development, Manufacture or Commercialization of any Co-Co Product or Co-Co Candidate, that is the subject of research, Development, Manufacture and/or Commercialization efforts under this Celgene Lead Co-Co Agreement, then such Party will notify the Patent Committee promptly, and Section 7.9 of the Master Collaboration Agreement shall apply (excluding Section 7.9.3); provided, however, that notwithstanding anything to the contrary in such provision of the Master Collaboration Agreement, unless Jounce has delivered a Jounce Opt-Out Notice in accordance with Section 4.4, the Parties shall cooperate through the Patent Committee regarding determining which Party should obtain a license, provided, further that unless the Parties otherwise agree, Celgene shall have the sole right, but not the obligation, to obtain a license from a Third Party under intellectual property rights that may be necessary for such activities with respect to U.S. Administration and/or ROW Administration or, to the extent any Co-Co Product is being Manufactured by or on behalf of Celgene anywhere in the Territory, with respect to such Manufacturing. Any amounts paid by (i) Celgene pursuant to any Third

The restrictions described in this Section 6.9.1 shall not apply to PD-1.

6.9.2 Exceptions.

rights regarding publication of the results arising pursuant to the conduct of activities under such agreement, and (iii) confidentiality obligations (collectively, (i) through (iii), the “Academic Essential Provisions”) in a manner that would result in any of the provisions covered by the Academic Essential Provisions in such existing agreement being less favorable to the contracting Party, or which would adversely affect any rights granted to Celgene or Jounce under this Celgene Lead Co-Co Agreement or any Development & Commercialization Agreement following such amendment without the prior written consent of the other Party (such consent not to be unreasonably withheld or delayed), or (b) the subject of a new agreement entered into between such Party and an academic institution or academic collaborator that contains terms and conditions with respect to the Academic Essential Provisions consistent with the terms and conditions of the agreements between such Party and an academic institution or academic collaborator entered into prior to the Effective Date of the Master Collaboration Agreement; provided that if any Academic Essential Provisions of an amendment described in (a) or an agreement described in (b) would not be consistent with the Academic Essential Provisions of the agreements between such Party and an academic institution or academic collaborator entered into prior to the Effective Date of the Master Collaboration Agreement, such Party shall not enter into such amendment or agreement on such inconsistent terms and conditions without the prior written consent of the other Party.

(b) Competitive Programs. Section 6.9.1 shall not apply if, during the Celgene Co-Co Term, any Party or its Affiliates merges or consolidates with, or otherwise acquires, a Third Party that is then engaged in activities that would otherwise constitute a breach of this Section 6.9 by any Party or its Affiliates (a “Competitive Program”) or acquires by license or otherwise a Competitive Program from a Third Party; it being understood and agreed that, unless the Parties agree otherwise in writing, such Party that is engaged in a Competitive Program (the “Competitive Program Party”) shall, within [***] after the date of such merger, consolidation or acquisition, notify the other Party that it intends to either: (i) terminate, or cause its relevant Affiliate to terminate, the Competitive Program or (ii) divest, or cause its relevant Affiliate to divest, whether by license or otherwise, the Competitive Program. If the Competitive Program Party notifies the other Party within such [***] period that it intends to terminate, or cause its relevant Affiliate to terminate, such Competitive Program, the Competitive Program Party or its relevant Affiliate, shall (i) terminate such Competitive Program as quickly as possible, and in any event within [***] (unless applicable Law requires a longer termination period) after the Competitive Program Party delivers such notice to the other Party; and (ii) confirm to the other Party when such termination has been completed, and the Competitive Program Party’s continuation of the Competitive Program during such [***] (or, as required by applicable Law, longer) period shall not constitute a breach of the Competitive Program Party’s exclusivity obligations under Section 6.9.1. If the Competitive Program Party notifies the other Party within such [***] period that it intends to divest such Competitive Program, the Competitive Program Party or its relevant Affiliate shall use all reasonable efforts to effect such divestiture as quickly as possible, and in any event within [***] after the Competitive Program Party delivers such notice to the other Party, and shall confirm to the other Party when such divestiture has been completed. If the Competitive Program Party or its relevant Affiliate fails to complete such divestiture within such [***] period, but has used reasonable efforts to effect such divestiture within such [***] period, then, unless otherwise required by applicable Law, such [***] period shall be extended for such additional reasonable period thereafter as is necessary to enable such Competitive Program to be in fact divested, not to exceed an additional [***];

provided that such additional [***] period shall be extended for such period as is necessary to obtain any governmental or regulatory approvals required to complete such divestiture if the Competitive Program Party or its relevant Affiliate is using good faith efforts to obtain such approvals. The Competitive Program Party’s continuation of the Competitive Program during such divestiture period shall not constitute a breach of the Competitive Program Party’s exclusivity obligations under Section 6.9.1.

(i) The [***] shall not constitute a breach of Section 6.9.1. Each Party shall report to the JSC on a Calendar Quarterly basis [***]. For clarity, providing at market price any supply of any biological or pharmaceutical product owned or controlled by a Party or any of its Affiliates that is then being commercialized to a Third Party conducting a human clinical trial with respect to a Biologic that is an [Immune Activator/Immune Suppressor] [select the applicable one before signing] through direct binding to the Co-Co Target in the Field for the Territory shall not constitute Development in violation of such Party’s exclusivity obligations under this Section 6.9 as long as neither such Party nor any of its Affiliates receives any other monetary consideration with respect to any product other than such product that is the subject of such clinical trial.

(ii) The entry into any Funding Agreement by Celgene or its Affiliates, either before or after the Celgene Lead Effective Date, and the performance by Celgene or its Affiliates of any obligations thereunder shall not constitute a breach of Section 6.9; it being understood and agreed that any exercise of any options by Celgene or its Affiliates shall be subject to Section 6.9.1.

(iii) The restrictions set forth in Section 6.9.1, as applicable, shall not be deemed to prevent either Party or its respective Affiliates from (A) fulfilling its obligations under this Celgene Lead Co-Co Agreement, and (B) engaging any subcontractors in accordance with Section 2.6 of this Celgene Lead Co-Co Agreement.

(iv) If a Change of Control occurs with respect to either Party with a Third Party and the Third Party already is conducting or is planning, as of the effective date of such Change of Control, to conduct activities on an existing program that would cause a Party or an Affiliate to violate Section 6.9, as applicable, (an “Acquirer Program”), then such Third Party will be permitted to continue such Acquirer Program and such initiation or continuation will not constitute a violation of Section 6.9, as applicable; provided that (i) none of the Collaboration IP or Joint Collaboration IP will be used in any Acquirer Program, (ii) none of the other Patents or Know-How licensed by either Party to the other Party pursuant to this Celgene Lead Co-Co Agreement will be used in any Acquirer Program, (iii) no Confidential Information of the other Party will be used in any such Acquirer Program, and (iv) the research or Development activities required under this Celgene Lead Co-Co Agreement will be conducted separately from any research or development activities directed to such Acquirer Program, including by the maintenance of separate lab notebooks and records (password-protected to the extent kept on a computer network) and the use of separate personnel working on each of the activities under this Celgene Lead Co-Co Agreement, and the activities covered under such Acquirer Program (except that this requirement shall not apply to personnel who have senior

research management roles and not project level research roles, provided such personnel in senior research management roles are not directly involved in the day-to-day activities under such Acquirer Program)..

(v) Notwithstanding anything to the contrary contained herein, each Party shall have, at all times, the right to conduct cell-based screens directed toward cell phenotypes, even if such cell-based screens result in the unanticipated identification or discovery of the Co-Co Target, and such activities shall not constitute a violation of this Section 6.9.

(d) Clinical Combinations. Both Parties shall at all times have the right to supply any Biologic owned or Controlled (other than under any Development & Commercialization Agreement) by such Party that is then being Commercialized to a Third Party conducting a Clinical Trial for a combination therapy involving such supplied Biologic so long as such supply of such Biologic to such Third Party is at a then-prevailing market price.

(b) any [***] under this Celgene Lead Co-Co Agreement; or

[***].

7.3 Notice of Claims. A Claim to which indemnification applies under Section 7.1 or Section 7.2 shall be referred to herein as an “Indemnification Claim.” If the Indemnitee intends to claim indemnification under this Article 7, the Party claiming indemnification (the “Indemnitee”) shall notify the indemnifying Party (the “Indemnitor”) in writing, promptly upon becoming aware of an Indemnification Claim, describing in reasonable detail the facts giving rise to the Indemnification Claim; provided, that an Indemnification Claim in respect of any action at law or suit in equity by or against a Third Party as to which indemnification shall be sought shall be given promptly after the action or suit is commenced (provided that the Indemnitee is aware of such commencement); and provided further, that the failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this Celgene Lead Co-Co Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice.

7.4 Indemnification Procedures. If an Indemnitee receives written notice of a Claim that the Indemnitee believes may result in a claim for indemnification under this Article 7, such Indemnitee shall deliver an Indemnification Claim to the Indemnitor in accordance with the provisions of Section 7.3. If the Litigation Conditions are satisfied, then the Indemnitor shall have the right to assume and control the defense of the Claim, at its own expense with counsel selected by it and reasonably acceptable to the Indemnitee, by delivering written notice of its assumption of such defense to the Indemnitee within [***] of its receipt of notice of such Claim from the Indemnitor (but the Indemnitor shall in any event have the right to assume and control the defense of a Claim that initially sought injunctive relief (including a declaratory judgment) from the Indemnitee when the only remaining dispute in such matter is the determination of non-injunctive relief or when the only remaining relief sought by the Third Party in such matter is non-injunctive relief, whichever is first); provided, however, that the Indemnitee shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the Indemnitor, if (a) representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflict of interests between such Indemnitee

and Indemnitor, (b) the Indemnitor has failed within a reasonable time to retain counsel, (c) the Indemnitee shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnitor, or (d) at any time the Litigation Conditions are not satisfied with respect to such Claim. If the Indemnitor assumes and controls the defense of such Claim, the Indemnitor shall keep the Indemnitee reasonably apprised of the status of the Claim and the Indemnitee shall be entitled to otherwise monitor such Claim at its sole cost and expense. If the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee or if the Indemnitor does not assume the defense of the Claim as described in this Section 7.4, the Indemnitee shall be permitted to assume and control the defense of such Claim (but shall have no obligation to do so) and in such event shall be entitled to settle or compromise the Indemnification Claims in its sole and reasonable discretion, provided that if the Indemnitee is entitled to assume the defense of the Claim pursuant to this Section 7.4 solely because the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee, then the Indemnitee shall not settle or compromise such Indemnification Claims in any manner that involves the payment of monetary damages or has an adverse effect on the Indemnitor’s rights or interests (including any rights under this Celgene Lead Co-Co Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this Celgene Lead Co-Co Agreement, any other Development & Commercialization Agreement or the Master Collaboration Agreement) without the prior written consent of the Indemnitor, which consent the Indemnitor shall not unreasonably withhold, condition or delay. If the Indemnitor has assumed and controls the defense of the Claim in accordance with this Section 7.4, (i) the Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld, conditioned or delayed and (ii) the Indemnitor shall not settle or compromise the Indemnification Claim in any manner that would result in the payment of amounts by the Indemnitee, impose any other obligation on the Indemnitee or otherwise have an adverse effect on the Indemnitee’s rights or interests (including any rights under this Celgene Lead Co-Co Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this Celgene Lead Co-Co Agreement or any other Development & Commercialization Agreement, or the Master Collaboration Agreement), without the prior written consent of the Indemnitee. In each case, the Party that is not controlling the defense of any Claim shall reasonably cooperate with the Party that is controlling the defense of such Claim, at the non-controlling Party’s expense and shall make available to the controlling Party all pertinent information under the control of the non-controlling Party, which information shall be subject to Article 8 of the Master Collaboration Agreement. Each Party shall use commercially reasonable efforts to avoid production of Confidential Information of the other Party (consistent with applicable Law and rules of procedure), and to cause all communications among employees, counsel and other representatives of such Party to be made so as to preserve any applicable attorney-client or work-product privileges.

7.5 U.S. Administration Liabilities. In the event that either Party (a) incurs any Third Party Damages in connection with a Claim for personal injury or death caused by the use of Co-Co Product for U.S. Administration, or any other Product Liability relating thereto, or (b) is required to make payments to any Third Party in order to acquire a license or other rights under Patents or Know-How necessary for the Development, Manufacture or Commercialization of Co-Co Product for U.S. Administration (collectively, “U.S. Administration Liabilities”), such

U.S. Administration Liabilities arising from or occurring as a result of the performance, in good faith, of the Development, Manufacture or Commercialization of Co-Co Product for U.S. Administration in accordance with this Celgene Lead Co-Co Agreement will be shared by the Parties as Operating Profits or Losses under the Profit & Loss Share, provided that the Operating Profits or Losses will not include U.S. Administration Liabilities of a Party or its Affiliates: (i) that are caused by a breach of this Celgene Lead Co-Co Agreement by such Party or its Affiliates; (ii) incurred with respect to or allocable to products other than Co-Co Product for U.S. Administration; or (iii) that are subject to indemnification by such Party pursuant to this Article 7 (and for clarity, if a Third Party makes a Claim directly against Jounce (or any of its Affiliates) or Celgene (or any of its Affiliates), respectively, that would otherwise be indemnified by Jounce or Celgene, respectively, if such Claim had been made against the other Party (or any of its Affiliates), then U.S. Administration Liabilities incurred by Jounce or Celgene in connection with such direct Claim will not be included in the calculation of the Operating Profits or Losses).

7.6 Insurance. Each Party shall maintain, at its cost, a program of insurance and/or self-insurance against liability (including product liability insurance) and other risks associated with its activities and obligations under this Celgene Lead Co-Co Agreement, including as applicable its Clinical Trials, the Commercialization of any Co-Co Candidate, and its indemnification obligations hereunder, in such amounts, subject to such deductibles and on such terms as are customary for such Party for the activities to be conducted by it under this Celgene Lead Co-Co Agreement.

7.7 Product Liability Costs. Solely with respect to Co-Co Products distributed in the United States, except with respect to such portion (if any) of Product Liabilities that are claims entitled to indemnification under Sections 7.1 or 7.2, the Parties shall be responsible for all Product Liabilities, all Direct Costs (including Out-of-Pocket Costs) (calculated using the applicable FTE Rate) incurred in connection with any litigation or proceeding related to such Third Party Products Liability Action, and all Direct Costs (including Out-of-Pocket Costs) (calculated using the applicable FTE Rate) incurred as follows:

7.7.1 All such costs and expenses incurred before the Jounce Opt-Out Date relating to Co-Co Products distributed in the United States prior to the Jounce Opt-Out Date shall be taken into account in determining the Profit & Loss Share as, and to the extent, provided in Exhibit D.

7.7.2 All such costs and expenses incurred after the Jounce Opt-Out Date relating to Co-Co Products shall be borne solely by Celgene if and only to the extent such Product Liabilities arose from Co-Co Products distributed after the Jounce Opt-Out Date.

7.8 LIMITATION OF LIABILITY. EXCEPT (A) FOR A BREACH OF SECTION 9.4 OR ARTICLE 6.9 OR (B) FOR CLAIMS THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 7 OR (C) FOR DAMAGES DUE TO THE FRAUD, MALICIOUS ACTIONS AND/OR INTENTIONAL TORT OF THE LIABLE PARTY, NEITHER JOUNCE NOR CELGENE, NOR ANY OF THEIR RESPECTIVE AFFILIATES WILL BE LIABLE TO THE OTHER PARTY TO THIS CELGENE LEAD CO-CO AGREEMENT OR ITS AFFILIATES UNDER THIS CELGENE LEAD CO-CO AGREEMENT FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR

PUNITIVE OR EXEMPLARY DAMAGES OR LOST PROFITS OR LOST DATA, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

(c) No Expiration in U.S. For clarity, unless earlier terminated pursuant to this Article 8 or there is a Jounce Opt-Out, this Celgene Lead Co-Co Agreement shall remain in effect in perpetuity with respect to the United States.

8.2 Termination Without Cause.

8.2.1 Termination by Celgene for Convenience. At any time during the Celgene Co-Co Term, Celgene shall have the right, at its sole discretion, to terminate this Celgene Lead Co-Co Agreement in its entirety, upon [***] prior written notice to Jounce hereunder; it being understood and agreed that Celgene shall be entitled to terminate upon [***] written notice at any time it reasonably determines that such termination is necessary to comply with any Antitrust Law.

8.2.2 Termination by Celgene for Safety Reasons. Celgene shall have the right to terminate this Celgene Lead Co-Co Agreement immediately on a Co-Co Candidate-by-Co-Co Candidate basis upon written notice to Jounce based on Safety Reasons (defined below). Upon such termination for Safety Reasons, subject to the terms and conditions of this Celgene Lead Co-Co Agreement, Celgene shall be responsible, at its expense, for the wind-down, if any, of any Development of the applicable Co-Co Candidate, and corresponding Co-Co Product (including any Clinical Trials for the applicable Co-Co Candidate or Co-Co Product being conducted by or on behalf of Celgene and any regulatory costs for closing out corresponding regulatory activities) and any Commercialization activities for the applicable Co-Co Candidate or Co-Co Product.

Upon such termination for Safety Reasons, all licenses granted by Jounce to Celgene under this Celgene Lead Co-Co Agreement shall terminate solely with respect to the applicable Co-Co Candidate or Co-Co Product. For purposes of this Celgene Lead Co-Co Agreement, “Safety Reason” means that the Data Safety Monitoring Board for a Clinical Trial, or the Parties by mutual written agreement, based upon additional information that becomes available or an analysis of then-existing information at any time, determines that Development or Commercialization, as applicable, of the Co-Co Candidate and/or Co-Co Products should be discontinued because the medical risk/benefit of the Co-Co Candidate or Co-Co Products is sufficiently unfavorable as to be incompatible with the welfare of patients to Develop or Commercialize or to continue to Develop or Commercialize it. If this Celgene Lead Co-Co Agreement is terminated pursuant to this Section 8.2.2, then subject to applicable data privacy laws, and on Jounce’s request, Celgene shall provide Jounce with full access to all relevant data relating to the terminated Co-Co Product.

8.3 Termination for Breach.

Notwithstanding the preceding sentence, the Cure Period for any allegation made in good faith as to a material breach under this Celgene Lead Co-Co Agreement will run from the date that written notice was first provided to the breaching Party by the non-breaching Party in accordance with Section 12.2 of the Master Collaboration Agreement. Any such termination of this Celgene Lead Co-Co Agreement under this Section 8.3.1 shall become effective at the end of the Cure Period, unless the breaching Party has cured any such breach or default prior to the expiration of such Cure Period, or, if such breach is not susceptible to cure within the Cure Period, then, the non-breaching Party’s right of termination shall be suspended only if and for so long as the breaching Party has provided to the non-breaching Party a written plan that is reasonably calculated to effect a cure and such plan is acceptable to the non-breaching Party, and the breaching Party commits to and carries out such plan as provided to the non-breaching Party. The Parties understand and agree that the totality of this Celgene Lead Co-Co Agreement and the totality of the circumstances with respect to this Celgene Lead Co-Co Agreement will be taken into account and assessed as a whole for purposes of determining whether a breach is material under this Celgene Lead Co-Co Agreement.

8.3.2 Additional Procedures for Termination by either Party for Failure of the Other Party to Use Commercially Reasonable Efforts. If either Party wishes to exercise its right to terminate this Celgene Lead Co-Co Agreement pursuant to Section 8.3.1 for the other Party’s material breach of its obligations to use Commercially Reasonable Efforts as set forth in Section 2.2.2, it shall provide to such other Party a written notice of its intent to exercise such right, which notice shall be labeled as a “notice of material breach for failure to use Commercially Reasonable Efforts,” and shall state the reasons and justification for such termination and recommending steps which such Party believes the other Party should take to cure such alleged breach. For any such notice of breach by a Party, the Cure Period shall be [***], and shall become effective in accordance with Section 8.3.1.

8.3.3 Disagreement as to Material Breach. If the Parties reasonably and in good faith disagree as to whether there has been a material breach pursuant to either Section 8.3.1 or 8.3.2, the Party that disputes that there has been a material breach may contest the allegation by referring such matter, within [***] following such notice of alleged material breach for resolution to the Executive Officers, who shall meet promptly to discuss the matter, and determine, within [***] following referral of such matter, whether or not a material breach has occurred pursuant to Section 8.3.1 or 8.3.2, as applicable. If the Executive Officers are unable to resolve a dispute within such [***] period after it is referred to them, the matter will be resolved as provided in Section 12.7 of the Master Collaboration Agreement.

8.3.3 or otherwise and such dispute is resolved in a manner in which no termination of this Celgene Lead Co-Co Agreement occurs with respect to such breach or the breaching Party cures the applicable breach during the Cure Period, then upon such resolution or cure Celgene will within [***] pay to Jounce the applicable milestone payment for each milestone achieved during the period between the notice of termination under Section 8.3.1 or 8.3.2 and the resolution of such dispute or cure of such breach, and if it was determined that Celgene wrongly asserted breach by Jounce under Section 8.3.1, then Celgene shall also pay interest on such amount at an annual rate equal to the lesser of: (a) [***] above the prime rate as published by Citibank, N.A., New York, New York, or any successor thereto, at 12:01 a.m. on the first day of each Calendar Quarter in which such payments are overdue or (b) the maximum rate permitted by applicable Law; in each case calculated on the number of days such payment is withheld, compounded monthly.

8.4 Termination for Bankruptcy. If either Party makes a general assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not dismissed, discharged, bonded or stayed within [***] after the filing thereof, the other Party may terminate this Celgene Lead Co-Co Agreement in its entirety effective immediately upon written notice to such Party. In connection therewith, the provisions of Section 6.1.5 shall apply.

8.5 Termination for Patent Challenges. Either Party shall have the right to terminate this Celgene Lead Co-Co Agreement solely on a Co-Co Product-by-Co-Co Product basis upon written notice in accordance with Section 12.2 of the Master Collaboration Agreement if the other Party or any Affiliate challenges the validity, scope or enforceability of or otherwise opposes any Patent (a) included in the Celgene Co-Co IP and that is licensed to Celgene under this Celgene Lead Co-Co Agreement, or (b) included in the Celgene Patents that is licensed to Jounce under this Celgene Lead Co-Co Agreement (other than in either case as may be necessary or reasonably required to assert a cross-claim or a counter-claim or to respond to a court request or order or administrative law, request or order) it being understood and agreed that either Party’s right to terminate this Celgene Lead Co-Co Agreement under this Section 8.5 shall not apply to any actions undertaken by an Affiliate of the other Party (the “Challenging Party”) that first becomes such an Affiliate as a result of a Business Combination involving the Challenging Party, where such new Affiliate was undertaking any of the activities described in the foregoing clause prior to such Business Combination; provided that a Party’s right to terminate this Celgene Lead Co-Co Agreement under this Section 8.5 shall apply to actions undertaken by such new Affiliate if the Challenging Party is the acquiror in such Business Combination and such new Affiliate does not terminate or otherwise cease such challenge or opposition within [***] after the effective date of such Business Combination. For the avoidance of doubt, an action by a Party or any Affiliate (collectively the “Prosecuting Party”) in accordance with this Celgene Lead Co-Co Agreement and the Master Collaboration Agreement to amend claims within a pending patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application or in defense of a Third Party proceeding, or to make a negative determination of patentability of claims of a patent application of the other Party or to abandon a patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application in accordance with Section 6.3, shall not constitute a challenge under this

Section 8.5.

8.6 Effects of Expiration or Termination.

8.6.1 License Upon Expiration. Upon expiration (but not upon earlier termination) of this Celgene Lead Co-Co Agreement in the ROW Territory (or any country(ies) therein), the license granted to Celgene in Section 6.1.1 shall, with respect to the ROW Territory (or such country(ies)), automatically convert to the applicable license set forth in Section 8.1.2.

8.6.2 Termination by Celgene Pursuant to Section 8.2, or by Jounce Pursuant to Section 8.3, 8.4, or 8.5.

(b) It is the intention of the Parties to interpret definitions to be consistent with this Exhibit D and Accounting Principles, it being understood and agreed that (i) [***]. Where such costs will be determined based on either Party’s system of cost or project accounting, each Party agrees to provide reasonable supporting documentation, as may be requested by the other Party, to ensure that each Party’s methodologies are reasonable and consistently applied. To the extent that such costs are not readily determinable based on the respective Party’s system of cost or project accounting, the JCC will develop a reasonable methodology for determining such costs. Reasonable methodologies may include a standard rate or some other appropriate basis for allocating costs. For billing and reporting, the statement of operations will be translated into U.S. Dollars in accordance with this Celgene Lead Co-Co Agreement.

Unless the schedule of such reporting is altered by the JSC, reporting by each Party for revenues and expenses will be as set forth in this Paragraph 2 of this Exhibit D.

(b) Celgene will prepare, for sales of Co-Co Product and Co-Co Diagnostic Product, a consolidated reporting of the activities undertaken by the Parties hereunder (including Operating Profit or Loss), the calculation of the Operating Profit or Loss sharing, and determination of the cash settlement as between the Parties. Celgene will provide Jounce within [***] after the end of each Calendar Quarter, a detailed statement showing the consolidated results and calculations of the Operating Profit or Loss sharing and cash settlement required in a format agreed to by the Parties (the “Report”). Jounce will cooperate as appropriate and provide Celgene with financial statements, within [***] of the end of each Calendar Quarter, for Jounce’s activities with respect to Co-Co Product and Co-Co Diagnostic Product (if any), prepared in accordance with the terms contained in the financial planning, accounting and reporting procedures set forth in this Exhibit D in order for Celgene to prepare the consolidated reports, including in reasonable detail the following costs and expenses incurred by Jounce (if any in such Calendar Quarter: (i) Cost of Goods Sold, (ii) Marketing Costs, (iii) Sales Costs, (iv) Distribution Costs, and (v) Other Operating Income/Expense.

(iv) If Celgene does not provide in the United States at any particular time, for any reason, the number of sales representatives specified in the U.S. Commercialization Plan to be provided for the United States, then Jounce will have the right to make up such shortfall using its sales representatives until such time as Celgene is able to provide its agreed upon number of sales representatives and for a period of [***] thereafter, and, for clarity, all costs incurred by Jounce related to Jounce’s making up such shortfall shall be included in the calculation of Operating Profits or Losses.

Each Party will train and instruct their respective sales representatives to make only those statements and claims regarding the Co-Co Product, including as to efficacy and safety, that are consistent with the Co-Co Product labeling and accompanying inserts and the approved promotional materials. For clarity, all marketing and promotional materials used in the United States must be approved by Jounce prior to use.

(d) Medical Affairs; Information. For Co-Co Products in the United States, the Parties will discuss the implementation of medical and scientific affairs and programs, including for professional symposia and other educational activities, and medical affairs studies based upon approved protocols, medical information support and medical communications and publishing activities, and the allocation of each Party to such activities in the United States, provided Jounce shall have the final decision-making authority to the conduct of such activities in the United States. The Parties acknowledge that in the United States each Party may receive requests for medical information concerning the Co-Co Product from members of the medical professions and consumers. Jounce will have the exclusive right to respond to questions and requests for information about Co-Co Product received from such Persons that warrant a response beyond the understanding of the sales representatives or that are beyond the scope of the Co-Co Product labels and inserts (each such request, an “Information Request”) and that are solely applicable to Co-Co Product for U.S. Administration.

At least [***] prior to the anticipated First Co-Co Sale of a Co-Co Product under this Jounce Lead Co-Co Agreement in the United States, the JCC shall discuss and agree upon the form and content for such U.S. Commercialization Report.

Subject to compliance with Section 2.6 of the Master Collaboration Agreement, Celgene shall have the right to grant sublicenses under the rights granted to it under Section 6.1.1 and 6.1.2, without the prior consent of Jounce (except as stated below in this Section 6.1.3), to any (a) Affiliate of Celgene, (b) Third Party subcontractor engaged by Celgene, and (c) Third Party (if for the Commercialization of Co-Co Products in the U.S., solely with Jounce’s prior written consent, such consent not to be unreasonably withheld) for the Development or Commercialization of any Co-Co Candidate, Co-Co Product or related Co-Co Diagnostic Product (other than for PD-1, for which no consent shall be required), provided that in the event Celgene grants a sublicense under Section 6.1.3(c) (but excluding sublicenses granted to contractors, agents and other Third Parties performing services for or on behalf of Celgene or its Affiliates), Celgene shall provide Jounce with a fully-executed copy of any agreement (redacted as necessary to protect confidential or commercially sensitive information that is not necessary to confirm compliance with this Jounce Lead Co-Co Agreement) reflecting any such sublicense promptly after the execution thereof. Subject to compliance with Section 2.6 of the Master Collaboration Agreement, Jounce shall have the right to grant sublicenses under the rights granted to it under Section 6.1.2, without the prior consent of Celgene, to any (a) Affiliate of Jounce, and (b) Third Party subcontractor engaged by Jounce. Each sublicense granted by either Party under this Section 6.1.3 shall be subject to and consistent with the terms and conditions of this Jounce Lead Co-Co Agreement.

6.1.4 Rights Retained by the Parties; No Implied Rights. Each Party retains the rights under all Know-How and Patents Controlled by such Party not expressly granted to the other Party pursuant to this Jounce Lead Co-Co Agreement or the Master Collaboration Agreement. Except as explicitly set forth in this Jounce Lead Co-Co Agreement, neither Party shall be deemed by estoppel, implication or otherwise to have granted the other Party any license or other right to any intellectual property rights of such Party. For clarity, Celgene retains all rights under Know-How and Patents relating to or Covering Celgene’s programs outside the scope of this Collaboration, including Celgene’s approved product programs, except as otherwise

granted by Celgene to Jounce in writing. For further clarity, Jounce retains all rights under Know-How and Patents relating to or Covering Jounce’s programs outside the scope of this Collaboration except as otherwise granted by Jounce to Celgene in writing.

6.1.5 Section 365(n) of the Bankruptcy Code. All licenses granted under this Jounce Lead Co-Co Agreement are deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined in Section 101 of such Code. Each Party, as licensee, may fully exercise all of its rights and elections under the Bankruptcy Code. The Parties further agree that, if a Party elects to retain its rights as a licensee under any Bankruptcy Code, such Party shall be entitled to a complete duplicate of, or complete access to any technology licensed to it hereunder and all embodiments of such technology. Such embodiments of the technology shall be delivered to the licensee Party not later than: (a) the commencement of bankruptcy proceedings against the licensor, upon written request, unless the licensor elects to perform its obligations under this Jounce Lead Co-Co Agreement, or (b) if not delivered under Section 6.1.5(a), upon the rejection of this Jounce Lead Co-Co Agreement by or on behalf of the licensor, upon written request. Any agreements supplemental hereto will be deemed to be “agreements supplementary to” this Jounce Lead Co-Co Agreement for purposes of Section 365(n) of the Bankruptcy Code.

6.3. Prosecution and Maintenance of Patents.

6.3.1 Jounce Co-Co Collaboration Patents. As between the Parties, subject to Section 4.4.3(n), and except as set forth in Section 6.3.3, the Parties will be jointly responsible for, and shall cooperate through the Patent Committee to Prosecute and Maintain, acting through Jounce, the Jounce Co-Co Collaboration Patents in the Territory, subject to the following terms and conditions: (a) the Parties shall continue to use the patent counsel used by Jounce prior to the Jounce Lead Effective Date to conduct such Prosecution and Maintenance of such Jounce Co-Co Collaboration Patents unless Celgene requests such counsel be changed due to such patent counsel, in Celgene’s good faith belief, not adequately conducting such Prosecution and Maintenance in the Territory, such request to be considered by Jounce in good faith and, if agreed to by Jounce, such Prosecution and Maintenance shall be transferred to a patent counsel reasonably acceptable to both Parties at Celgene’s expense; and (b) in the event Jounce disagrees

with Celgene’s comments and recommended actions for the Jounce Co-Co Collaboration Patents in the Territory, Jounce will have final decision-making authority in the U.S., and Celgene will have final decision-making authority in the ROW Territory, in each case subject to Section 6.3.2.

6.3.2 Backup Right. Subject to Section 4.4.3(n), if Jounce decides not to file a Jounce Co-Co Collaboration Patent or intends to allow a Jounce Co-Co Collaboration Patent to lapse or become abandoned without having first filed a substitute in the Territory, it shall notify Celgene of, and consult with Celgene with respect to, such decision or intention at least [***] prior to the date upon which the subject matter of such Patent shall become unpatentable or such Patent shall lapse or become abandoned, and Celgene shall thereupon have the right (but not the obligation) to assume the Prosecution and Maintenance thereof at Celgene’s expense with counsel of its choice.

6.3.3 Prosecution and Maintenance of Third Party Patents. Notwithstanding Sections 6.3.1 and 6.3.2, Celgene acknowledges that the MSKCC has the first right to Prosecute and Maintain the Patents licensed to Jounce pursuant to the MSKCC Agreement (the “MSKCC Patents”). If MSKCC decides to refrain from or to cease prosecuting or maintaining the MSKCC Patents, then under the MSKCC Agreement, Jounce has the right to continue such prosecution or maintenance in accordance with the MSKCC Agreement. If Jounce continues such activities, then Jounce shall proceed as provided in this Section 6.3 with respect to the MSKCC Patents, subject to any obligations of Jounce to any Third Party licensees with respect to the MSKCC Patents existing as of the Jounce Lead Effective Date; provided that Celgene agrees and acknowledges that Jounce is obligated to comply with the obligations described in the MSKCC Agreement with respect to Prosecution and Maintenance of Patents licensed under the MSKCC Agreement, including to provide to MSKCC any and all draft filings and applications for the MSKCC Patents, as well as responses to patent authorities in connection therewith, before filing such items, for review and comment by MSKCC.

6.3.4 Costs of Prosecution and Maintenance. Celgene shall bear all of the costs and expenses of Prosecution and Maintenance of the Jounce Co-Co Collaboration Patents in the ROW Territory. For Prosecution and Maintenance of the Jounce Co-Co Collaboration Patents in the US, all costs and expenses shall, prior to the delivery of a Jounce Opt-Out Notice in accordance with Section 4.4, be allocated [***] to Jounce and [***] to Celgene for the ICOS Activator Program and shared equally for the First Other Program, and after the delivery of a Jounce Opt-Out Notice in accordance with Section 4.4, shall be borne in their entirety by Celgene.

6.4. Defense of Claims Brought by Third Parties.

ROW Territory, and Jounce shall have the sole right, but not the obligation, to defend and dispose (including through settlement or license) such claim in the United States.

6.4.2 Costs. The costs and expenses incurred by the Parties in connection with defense of any claim described in Section 6.4.1 in the U.S. shall be shared by the Parties in accordance with the Profit & Loss Share, and with respect to any such claim in the ROW Territory shall be borne solely by Celgene, unless otherwise agreed in writing by the Parties. For clarity, this Section 6.4.2 is intended to address the Parties’ defense costs in such claim, and if as a result of any such defense of such claim, a Party obtains a license under Third Party intellectual property rights, Section 6.8 may apply to the amounts due to any such Third Party pursuant to such license.

6.5. Enforcement of Patents.

6.5.1 Notice. If any Party learns of an infringement or threatened infringement by a Third Party with respect to any Jounce Co-Co Collaboration Patent, including actual or alleged infringement under 35 USC §271(e)(2) that is or would be infringing activity involving the using, making, importing, offering for sale or selling of compounds or products that are substantially the same as or otherwise competitive with the Co-Co Candidate, Co-Co Products or Co-Co Diagnostic Products (including Comparable Co-Co Third Party Products) in the Field (“Competitive Infringement”), such Party shall promptly notify the other Party and shall provide such other Party with available evidence of such Competitive Infringement. For any Competitive Infringement, each Party shall share with the other Party all information available to it regarding such actual or alleged infringement.

6.5.2 Enforcement of Jounce Co-Co Collaboration Patent and Celgene Patents.

(a) Celgene ROW Initial Enforcement. As between the Parties, and subject to Section 6.7, Celgene shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any Competitive Infringement in the ROW Territory of (A) any Jounce Co-Co Collaboration Patent that is exclusively licensed to Celgene under this Jounce Lead Co-Co Agreement and that solely Covers Co-Co Products or the Co-Co Candidate (such Patents, the “Jounce Co-Co Product Patents”) and (B) any Celgene Patent, in each case by counsel of its own choice, in Celgene’s own name and under Celgene’s direction and control, provided that Celgene shall keep Jounce, through the JSC and/or Patent Committee, reasonably informed as to the status of, and all material developments in such action, including considering in good faith, the input of Jounce regarding the strategy and handling of such enforcement activities.

(b) Jounce U.S. Initial Enforcement. As between the Parties, and subject to Section 6.7, Jounce shall have the first right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to any Competitive Infringement in the United States of (A) any Jounce Co-Co Product Patent, and (B) any Celgene Patent, in each case by counsel of its own choice, in Jounce’s own name and under Jounce’s direction and control, provided that Jounce shall keep Celgene, through the JSC and/or Patent Committee, reasonably informed as to the status of, and all material developments in such action, including considering in good faith, the input of Celgene regarding the strategy and handling of such enforcement

activities. Notwithstanding anything in this Section 6.5 to the contrary, Celgene shall have final decision-making authority as to representations made in any proceedings under this Section 6.5 with respect to any Celgene Independent Products.

(c) Timing. The Party having the first right to enforce a Patent pursuant to Sections 6.5.2(a) through 6.5.2(b) will have a period of [***] after its delivery of notice and evidence pursuant to Section 6.5.1 or receipt of written notice from a Third Party that reasonably evidences any action or proceeding with respect to any Co-Co Competitive Infringement described in Section 6.5.2(a), as applicable (such action or proceeding a “Co-Co Enforcement Proceeding”), to elect to so enforce such Jounce Co-Co Collaboration Patent or Celgene Patent, as applicable, in the applicable jurisdiction (or to settle or otherwise secure the abatement of such Co-Co Competitive Infringement), provided however, that such period will be (i) more than [***] to the extent applicable Law prevents earlier enforcement of such Jounce Co-Co Collaboration Patent or Celgene Patent, as applicable, and provided further that if such period is extended because applicable Law prevents earlier enforcement, the Party having the first right to enforce shall have until the date that is [***] following the date upon which applicable Law first permits such Co-Co Enforcement Proceeding, and (ii) less than [***] to the extent that a delay in bringing such Co-Co Enforcement Proceeding against such alleged Third Party infringer would limit or compromise the remedies (including monetary relief, and stay of regulatory approval) available against such alleged Third Party infringer. In the event the Party having the first right to enforce does not so elect to enforce or settle or otherwise secure the abatement of such Co-Co Competitive Infringement before the first to occur of (A) the expiration of the applicable period of time set forth in above, or (B) [***] before the expiration of any time period under applicable Law, that would, if a Co-Co Enforcement Proceeding was not filed within such time period, limit or compromise the remedies available from such Co-Co Enforcement Proceeding, such Party having the first right to enforce will so notify the other Party in writing and in the case where such other Party then desires to commence a suit or take action to enforce the applicable Jounce Co-Co Collaboration Patent or Celgene Patent with respect to such Co-Co Competitive Infringement in the applicable jurisdiction, such other Party will, subject to Section 6.5.2(e), thereafter have the right to commence such a suit or take such action to enforce the applicable Jounce Co-Co Collaboration Patent or Celgene Patent, as applicable (such action, a “Co-Co Step-In Proceeding”), at such other Party’s expense. Notwithstanding anything in this Section 6.5 to the contrary, Celgene shall have final decision-making authority as to representations made in any proceedings under this Section 6.5 with respect to any Celgene Independent Products.

(d) Right to Participate; Joinder. The non-enforcing Party in relation to any enforcement action or proceeding set forth in Sections 6.5.2(a) through 6.5.2(b) will have the right, at its own expense and by counsel of its choice, to be represented in any such action or proceeding. In the case of any Co-Co Enforcement Proceeding or Co-Co Step-In Proceeding, at the enforcing Party’s written request, and at the enforcing Party’s expense (subject to Section 6.5.2(h)), the other Party shall join any such action or proceeding as a party and will use Commercially Reasonable Efforts to cause any Third Party as necessary to join such action or proceeding as a party if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable Law to pursue such action or proceeding, or if the JSC (with respect to enforcement activities relating to Co-Co Product for U.S. Administration) determines

that such joinder is necessary or desirable. All time periods set forth in this Section 6.5.2 shall be subject to applicable Law, which may prevent earlier enforcement.

(e) Cooperation. In addition to the obligations set forth in Section 6.5.2(a) through 6.5.2(f), each Party will provide to the Party enforcing any such rights under Sections 6.5.2(a) or 6.5.2(b), as applicable, reasonable assistance and cooperation in such enforcement, at such enforcing Party’s request and expense (subject to Section 6.5.2(h)). The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts. The Parties will coordinate any Co-Co Enforcement Proceeding with respect to the Jounce Co-Co Collaboration Patent and Celgene Patents through the JSC and/or Patent Committee. Each Party bringing any such action or proceeding in accordance with this Section 6.5 shall have an obligation to consult with the other Party and will take comments of such other Party into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any Jounce Co-Co Collaboration Patent and Celgene Patent that is the subject of such proceeding.

(g) Settlement. Notwithstanding anything to the contrary in this Section 6.5, a settlement or consent judgment or other voluntary final disposition of a suit under this Section 6.5: (i) with respect to enforcement in the ROW Territory, may be entered into without the consent of the Party not bringing suit, and (ii) with respect to enforcement in the U.S., may only be entered into with the approval of the JSC; provided, however, that in any event, any such settlement, consent judgment or other disposition of any action or proceeding by a Party under this Article 6 shall not, without the consent of the Party not bringing suit, (a) impose any liability or obligation on the Party not bringing suit, (b) include the grant of any license, covenant or other rights to any Third Party that would conflict with or reduce the scope of the subject matter included under the licenses granted to the Party not bringing suit under this Jounce Lead Co-Co Agreement, (c) conflict with or reduce the scope of the subject matter claimed in any Patent owned by the Party not bringing suit, or (d) adversely affect the interest of the Party not bringing suit in any material respect, provided that such consent shall not be unreasonably withheld, conditioned or delayed.

(h) Costs of Enforcement. Except as otherwise set forth in this Section 6.5:

(i) ROW. Each Party shall bear all of its own internal costs incurred in connection with its activities under this Section 6.5 that relate to a Co-Co Enforcement Proceeding or a Co-Co Step-In Proceeding relating to Jounce Co-Co Patents or Celgene Patents in the ROW Territory, and, if a Party commences a Co-Co Enforcement Proceeding or a Co-Co Step-In Proceeding in the ROW Territory, it shall bear all external costs and expenses for such action; and

(ii) U.S. All Direct Costs and reasonable and documented external costs and expenses incurred by either Party in pursuing any Co-Co Enforcement Proceeding or a Co-Co Step-In Proceeding of the Jounce Co-Co Patents or the Celgene Patents in the U.S. in accordance with this Section 6.5 shall be shared by the Parties in accordance with the Profit & Loss Share.

(i) Recoveries. Any damages or other monetary awards recovered in any action, suit or proceeding brought under this Section 6.5 shall be shared as follows:

(i) Initial Allocation. Such damages or other sums recovered shall first be applied to reimburse each Party for all of its Out-of-Pocket Costs expenses incurred by each Party directly in connection with such action (including, for this purpose, a reasonable allocation of expenses of outside counsel), and if such recovery is insufficient to cover all such costs and expenses of both Parties, it shall be shared in proportion to the total of such costs and expenses incurred by each Party; and

(j) Opt-Out by Jounce. Notwithstanding any other provisions in this Section 6.5.2, if Jounce opts-out of its rights and responsibilities under Section 4.4 of this Jounce Lead Co-Co Agreement, Celgene shall have the sole right to enforce Jounce Co-Co Product Patents and Celgene Patents in the U.S. and in the ROW Territory at its own expense, and shall have sole right of settlement of and enforcement suit with respect to such Patents, and Celgene shall retain [***] of remaining proceeds under 6.5.2(i)(ii) in the U.S. and in the ROW Territory.

6.6. Patent Term Extensions. Subject to Section 4.4.3(n), in the course of conducting activities pursuant to this Jounce Lead Co-Co Agreement, Jounce and Celgene shall discuss and seek to reach mutual agreement as to which, if any, of the Patents within the Jounce Co-Co Collaboration Patents or Celgene Patents that Cover the Co-Co Candidate, or Co-Co Products containing the Co-Co Candidate, for which the Parties shall apply to obtain patent term extensions, adjustments, restorations, or supplementary protection certificates under applicable Laws, based on the best commercial interests of the Co-Co Candidate or Co-Co Products; it being understood and agreed that, (a) if Celgene seeks a patent term extension in the ROW Territory, then Jounce agrees to negotiate in good faith with respect to any measures required by applicable Law for Celgene to obtain such extension and (b) if Jounce seeks a patent term extension in the United States, then Celgene agrees to negotiate in good faith with respect to any measures required by applicable Law for Jounce to obtain such extension. If the Parties are unable to reach mutual agreement, Celgene shall have the right to make the final decision in the ROW Territory and Jounce shall have the right to make the final decision in the United States.

6.7. Third Party Licenses. If, at any time during the Jounce Co-Co Term, either Party reasonably determines that any Third Party intellectual property rights may be necessary for the Development, Manufacture or Commercialization of any Co-Co Product or Co-Co Candidate, that is the subject of research, Development, Manufacture and/or Commercialization efforts under this Jounce Lead Co-Co Agreement, then such Party will notify the Patent Committee promptly, and Section 7.9 of the Master Collaboration Agreement shall apply (excluding Section 7.9.3); provided, however, that notwithstanding anything to the contrary in such provision of the Master Collaboration Agreement, unless Jounce has delivered a Jounce Opt-Out Notice in accordance with Section 4.4, the Parties shall cooperate through the Patent Committee regarding determining which Party should obtain a license, provided, further that unless the Parties otherwise agree, the following shall apply: (a) Jounce shall have the sole right, but not the obligation, to obtain a license from a Third Party under intellectual property rights that may be necessary for such activities with respect to U.S. Administration or, to the extent any Co-Co Product is being Manufactured by or on behalf of Jounce anywhere in the Territory, with respect to such Manufacturing; and (b) Celgene shall have the sole right, but not the obligation, to obtain a license from a Third Party under intellectual property rights that may be necessary for such activities with respect to ROW Administration or, to the extent any Co-Co Product is being Manufactured by or on behalf of Celgene anywhere in the Territory, with respect to such Manufacturing. Any amounts paid by (i) Celgene pursuant to any Third Party License Agreement entered into pursuant to Section 7.9 of the Master Collaboration Agreement or this Section 6.7 for ROW Administration shall be applied to reduce royalties payable to Jounce, to the extent provided in Section 5.3.3, or (ii) by Jounce or Celgene pursuant to this Section 6.7 or by Celgene pursuant to Section 7.9 of the Master Collaboration Agreement, in each case for U.S. Administration, shall be shared by the Parties in accordance with the Profit & Loss Share.

6.9.1 Exclusivity Obligations. From the Jounce Lead Effective Date until the end of the Term, each of the Parties, on behalf of itself and its Affiliates, hereby covenants and agrees that, subject to Section 9.4, neither such Party nor its Affiliates shall, directly or indirectly, alone or with any Third Party: (i) alone or with or for any Third Party, (x) research (including screen) in the Field any Biologic (which, in the case of an Antibody, has one or more of the same CDR sequences of either any Collaboration Candidate hereunder or the Co-Co Candidate Specifically Directed to the Co-Co Target) or (y) research (including screen), Develop, Manufacture or Commercialize any Biologic that is an [Immune Activator/Immune Suppressor] [select the applicable one before signing] in the Field and that is Specifically Directed to the Co-Co Target, other than in performance of activities under this Jounce Lead Co-Co Agreement; except for (x) Co-Co Products (including those activities specifically permitted following termination of this Jounce Lead Co-Co Agreement) and (y) Programs (as defined in the Master Collaboration Agreement) directed to the Co-Co Target (A) that are being conducted pursuant to the Master Collaboration Agreement, (B) to which Celgene has exercised its Option (as defined in the Master Collaboration Agreement) under the Master Collaboration Agreement or (C) the rights to which have reverted to Jounce in accordance with the terms of the Master

Collaboration Agreement; (ii) grant a license or sublicense to research (including screen), Develop, Manufacture or Commercialize any Biologic in the Field or pharmaceutical product in the Field, in each case described in clause (i) above as Specifically Directed to the Co-Co Target, as part of a Third Party Transaction; or (iii) except as expressly permitted under Section 9.4, transfer, assign, convey or otherwise sell any Biologic or pharmaceutical product described in clause (i) above. The restrictions described in this Section 6.9.1 shall not apply to PD-1.

6.9.2 Exceptions.

(a) Academic Collaborations. Notwithstanding the provisions of Section 6.9.1, each Party shall be permitted to perform any of the activities that would otherwise be prohibited under Section 6.9.1 and in relation to the Co-Co Target, if such activities are (a) the subject of an existing agreement between such Party and an academic institution or academic collaborator entered into prior to the Effective Date of the Master Collaboration Agreement, provided that such Party shall not be permitted to amend any such agreement unless such amendment contains provisions consistent with the terms and conditions of such agreement in effect as of the Effective Date of the Master Collaboration Agreement with respect to (i) ownership and licenses of pre-existing intellectual property rights, as well as intellectual property rights and inventions arising pursuant to the conduct of activities under such agreement, (ii) rights regarding publication of the results arising pursuant to the conduct of activities under such agreement, and (iii) confidentiality obligations (collectively, (i) through (iii), the “Academic Essential Provisions”) in a manner that would result in any of the provisions covered by the Academic Essential Provisions in such existing agreement being less favorable to the contracting Party, or which would adversely affect any rights granted to Celgene or Jounce under this Jounce Lead Co-Co Agreement or any Development & Commercialization Agreement following such amendment without the prior written consent of the other Party (such consent not to be unreasonably withheld or delayed), or (b) the subject of a new agreement entered into between such Party and an academic institution or academic collaborator that contains terms and conditions with respect to the Academic Essential Provisions consistent with the terms and conditions of the agreements between such Party and an academic institution or academic collaborator entered into prior to the Effective Date of the Master Collaboration Agreement; provided that if any Academic Essential Provisions of an amendment described in (a) or an agreement described in (b) would not be consistent with the Academic Essential Provisions of the agreements between such Party and an academic institution or academic collaborator entered into prior to the Effective Date of the Master Collaboration Agreement, such Party shall not enter into such amendment or agreement on such inconsistent terms and conditions without the prior written consent of the other Party.

(b) Competitive Programs. Section 6.9.1 shall not apply if, during the Jounce Co-Co Term, any Party or its Affiliates merges or consolidates with, or otherwise acquires, a Third Party that is then engaged in activities that would otherwise constitute a breach of this Section 6.9 by any Party or its Affiliates (a “Competitive Program”) or acquires by license or otherwise a Competitive Program from a Third Party; it being understood and agreed that, unless the Parties agree otherwise in writing, such Party that is engaged in a Competitive Program (the “Competitive Program Party”) shall, within [***] after the date of such merger, consolidation or acquisition, notify the other Party that it intends to either: (i) terminate, or cause its relevant Affiliate to terminate, the Competitive Program or (ii) divest, or cause its relevant Affiliate to

divest, whether by license or otherwise, the Competitive Program. If the Competitive Program Party notifies the other Party within such [***] period that it intends to terminate, or cause its relevant Affiliate to terminate, such Competitive Program, the Competitive Program Party or its relevant Affiliate, shall (i) terminate such Competitive Program as quickly as possible, and in any event within [***] (unless applicable Law requires a longer termination period) after the Competitive Program Party delivers such notice to the other Party; and (ii) confirm to the other Party when such termination has been completed, and the Competitive Program Party’s continuation of the Competitive Program during such [***] (or, as required by applicable Law, longer) period shall not constitute a breach of the Competitive Program Party’s exclusivity obligations under Section 6.9.1. If the Competitive Program Party notifies the other Party within such [***] period that it intends to divest such Competitive Program, the Competitive Program Party or its relevant Affiliate shall use all reasonable efforts to effect such divestiture as quickly as possible, and in any event within [***] after the Competitive Program Party delivers such notice to the other Party, and shall confirm to the other Party when such divestiture has been completed. If the Competitive Program Party or its relevant Affiliate fails to complete such divestiture within such [***] period, but has used reasonable efforts to effect such divestiture within such [***] period, then, unless otherwise required by applicable Law, such [***] period shall be extended for such additional reasonable period thereafter as is necessary to enable such Competitive Program to be in fact divested, not to exceed an additional [***]; provided that such additional [***] period shall be extended for such period as is necessary to obtain any governmental or regulatory approvals required to complete such divestiture if the Competitive Program Party or its relevant Affiliate is using good faith efforts to obtain such approvals. The Competitive Program Party’s continuation of the Competitive Program during such divestiture period shall not constitute a breach of the Competitive Program Party’s exclusivity obligations under Section 6.9.1.

(ii) The entry into any Funding Agreement by Celgene or its Affiliates, either before or after the Jounce Lead Effective Date, and the performance by Celgene or its Affiliates of any obligations thereunder shall not constitute a breach of Section 6.9; it being understood and agreed that any exercise of any options by Celgene or its Affiliates shall be subject to Section 6.9.1.

(iii) The restrictions set forth in Section 6.9.1, as applicable, shall not be deemed to prevent either Party or its respective Affiliates from (A) fulfilling its obligations

under this Jounce Lead Co-Co Agreement, and (B) engaging any subcontractors in accordance with Section 2.6 of this Jounce Lead Co-Co Agreement.

(iv) If a Change of Control occurs with respect to either Party with a Third Party and the Third Party already is conducting or is planning, as of the effective date of such Change of Control, to conduct activities on an existing program that would cause a Party or an Affiliate to violate Section 6.9, as applicable, (an “Acquirer Program”), then such Third Party will be permitted to continue such Acquirer Program and such initiation or continuation will not constitute a violation of Section 6.9, as applicable; provided that (i) none of the Collaboration IP or Joint Collaboration IP will be used in any Acquirer Program, (ii) none of the other Patents or Know-How licensed by either Party to the other Party pursuant to this Jounce Lead Co-Co Agreement will be used in any Acquirer Program, (iii) no Confidential Information of the other Party will be used in any such Acquirer Program, and (iv) the research or Development activities required under this Jounce Lead Co-Co Agreement will be conducted separately from any research or development activities directed to such Acquirer Program, including by the maintenance of separate lab notebooks and records (password-protected to the extent kept on a computer network) and the use of separate personnel working on each of the activities under this Jounce Lead Co-Co Agreement, and the activities covered under such Acquirer Program (except that this requirement shall not apply to personnel who have senior research management roles and not project level research roles, provided such personnel in senior research management roles are not directly involved in the day-to-day activities under such Acquirer Program)..

If the Litigation Conditions are satisfied, then the Indemnitor shall have the right to assume and control the defense of the Claim, at its own expense with counsel selected by it and reasonably acceptable to the Indemnitee, by delivering written notice of its assumption of such defense to the Indemnitee within [***] of its receipt of notice of such Claim from the Indemnitor (but the Indemnitor shall in any event have the right to assume and control the defense of a Claim that initially sought injunctive relief (including a declaratory judgment) from the Indemnitee when the only remaining dispute in such matter is the determination of non-injunctive relief or when the only remaining relief sought by the Third Party in such matter is non-injunctive relief, whichever is first); provided, however, that the Indemnitee shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the Indemnitor, if (a) representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflict of interests between such Indemnitee and Indemnitor, (b) the Indemnitor has failed within a reasonable time to retain counsel, (c) the Indemnitee shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnitor, or (d) at any time the Litigation Conditions are not satisfied with respect to such Claim. If the Indemnitor assumes and controls the defense of such Claim, the Indemnitor shall keep the Indemnitee reasonably apprised of the status of the Claim and the Indemnitee shall be entitled to otherwise monitor such Claim at its sole cost and expense. If the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee or if the Indemnitor does not assume the defense of the Claim as described in this Section 7.4, the Indemnitee shall be permitted to assume and control the defense of such Claim (but shall have no obligation to do so) and in such event shall be entitled to settle or compromise the Indemnification Claims in its sole and reasonable discretion, provided that if the Indemnitee is entitled to assume the defense of the Claim pursuant to this Section 7.4 solely because the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee, then the Indemnitee shall not settle or compromise such Indemnification Claims in any manner that involves the payment of monetary damages or has an adverse effect on the Indemnitor’s rights or interests (including any rights under this Jounce Lead Co-Co Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this Jounce Lead Co-Co Agreement, any other Development & Commercialization Agreement or the Master Collaboration Agreement) without the prior written consent of the Indemnitor, which consent the Indemnitor shall not unreasonably withhold, condition or delay. If the Indemnitor has assumed and controls the defense of the Claim in accordance with this Section 7.4, (i) the Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld, conditioned or delayed and (ii) the Indemnitor shall not settle or compromise the Indemnification Claim in any manner that would result in the payment of amounts by the Indemnitee, impose any other obligation on the Indemnitee or otherwise have an adverse effect on the Indemnitee’s rights or interests (including any rights under this Jounce

Lead Co-Co Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this Jounce Lead Co-Co Agreement or any other Development & Commercialization Agreement, or the Master Collaboration Agreement), without the prior written consent of the Indemnitee. In each case, the Party that is not controlling the defense of any Claim shall reasonably cooperate with the Party that is controlling the defense of such Claim, at the non-controlling Party’s expense and shall make available to the controlling Party all pertinent information under the control of the non-controlling Party, which information shall be subject to Article 8 of the Master Collaboration Agreement. Each Party shall use commercially reasonable efforts to avoid production of Confidential Information of the other Party (consistent with applicable Law and rules of procedure), and to cause all communications among employees, counsel and other representatives of such Party to be made so as to preserve any applicable attorney-client or work-product privileges.

7.5. U.S. Administration Liabilities. In the event that either Party (a) incurs any Third Party Damages in connection with a Claim for personal injury or death caused by the use of Co-Co Product for U.S. Administration, or any other Product Liability relating thereto, or (b) is required to make payments to any Third Party in order to acquire a license or other rights under Patents or Know-How necessary for the Development, Manufacture or Commercialization of Co-Co Product for U.S. Administration (collectively, “U.S. Administration Liabilities”), such U.S. Administration Liabilities arising from or occurring as a result of the performance, in good faith, of the Development, Manufacture or Commercialization of Co-Co Product for U.S. Administration in accordance with this Jounce Lead Co-Co Agreement will be shared by the Parties as Operating Profits or Losses under the Profit & Loss Share, provided that the Operating Profits or Losses will not include U.S. Administration Liabilities of a Party or its Affiliates: (i) that are caused by a breach of this Jounce Lead Co-Co Agreement by such Party or its Affiliates; (ii) incurred with respect to or allocable to products other than Co-Co Product for U.S. Administration; or (iii) that are subject to indemnification by such Party pursuant to this Article 7 (and for clarity, if a Third Party makes a Claim directly against Jounce (or any of its Affiliates) or Celgene (or any of its Affiliates), respectively, that would otherwise be indemnified by Jounce or Celgene, respectively, if such Claim had been made against the other Party (or any of its Affiliates), then U.S. Administration Liabilities incurred by Jounce or Celgene in connection with such direct Claim will not be included in the calculation of the Operating Profits or Losses).

7.6. Insurance. Each Party shall maintain, at its cost, a program of insurance and/or self-insurance against liability (including product liability insurance) and other risks associated with its activities and obligations under this Jounce Lead Co-Co Agreement, including as applicable its Clinical Trials, the Commercialization of any Co-Co Candidate, and its indemnification obligations hereunder, in such amounts, subject to such deductibles and on such terms as are customary for such Party for the activities to be conducted by it under this Jounce Lead Co-Co Agreement.

7.7. Product Liability Costs. Solely with respect to Co-Co Products distributed in the United States, except with respect to such portion (if any) of Product Liabilities that are claims entitled to indemnification under Sections 7.1 or 7.2, the Parties shall be responsible for all Product Liabilities, all Direct Costs (including Out-of-Pocket Costs) (calculated using the applicable FTE Rate) incurred in connection with any litigation or proceeding related to such

Third Party Products Liability Action, and all Direct Costs (including Out-of-Pocket Costs) (calculated using the applicable FTE Rate) incurred as follows:

7.8. LIMITATION OF LIABILITY. EXCEPT (A) FOR A BREACH OF SECTION 9.4 OR ARTICLE 6.9 OR (B) FOR CLAIMS THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 7 OR (C) FOR DAMAGES DUE TO THE FRAUD, MALICIOUS ACTIONS AND/OR INTENTIONAL TORT OF THE LIABLE PARTY, NEITHER JOUNCE NOR CELGENE, NOR ANY OF THEIR RESPECTIVE AFFILIATES WILL BE LIABLE TO THE OTHER PARTY TO THIS JOUNCE LEAD CO-CO AGREEMENT OR ITS AFFILIATES UNDER THIS JOUNCE LEAD CO-CO AGREEMENT FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR PUNITIVE OR EXEMPLARY DAMAGES OR LOST PROFITS OR LOST DATA, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

ARTICLE 8
JOUNCE CO-CO TERM AND TERMINATION

8.1. Jounce Co-Co Term; Expiration.

8.1.1 Co-Co Term. This Jounce Lead Co-Co Agreement shall become effective on the Jounce Lead Effective Date and, unless earlier terminated pursuant to this Article 8, shall remain in effect until it expires (the “Jounce Co-Co Term”):

(a) on a Co-Co Product-by-Co-Co Product and country-by-country basis in the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory), this Jounce Lead Co-Co Agreement shall expire on the date of the expiration of all applicable Co-Co Royalty Terms with respect to such Co-Co Product in such country; and

(b) in its entirety with respect to the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory) only upon the expiration of all applicable Co-Co Royalty Terms in the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory) under this Jounce Lead Co-Co Agreement with respect to all Co-Co Products in the ROW Territory or the Territory, as applicable.

8.1.2 Effect of Expiration. After the expiration of the Jounce Co-Co Term in the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory) or specific countries therein pursuant to Section 8.1.1 above, the following terms shall apply solely with respect to the ROW Territory (or such countries therein):

(a) Licenses after Co-Co Product Expiration. After expiration of the Jounce Co-Co Term (but not after early termination) with respect to any Co-Co Product in a country in the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory) pursuant to Section 8.1.1(a), Celgene shall have an exclusive, fully-paid, royalty-free, irrevocable, non-terminable, in such country right and license, with the right to grant sublicenses, under the Jounce Co-Co IP to develop, manufacture, have manufactured, use, offer for sale, sell, import and otherwise commercialize such Co-Co Product and related Co-Co Diagnostic Products in the Field in such country.

(b) Licenses after Expiration of Co-Co Agreement. After expiration of the Jounce Co-Co Term (but not after early termination) with respect to this Jounce Lead Co-Co Agreement in its entirety pursuant to Section 8.1.1(b), Celgene shall have an exclusive, fully-paid, royalty-free, irrevocable, non-terminable, in the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory) right and license, with the right to grant sublicenses, under the Jounce Co-Co IP to develop, manufacture, have manufactured, use, offer for sale, sell, import and otherwise commercialize Co-Co Products and Co-Co Diagnostic Products in the Field in the ROW Territory (or, in the event of any Jounce Opt-Out, the Territory).

(c) No Expiration in U.S. For clarity, unless earlier terminated pursuant to this Article 8 or there is a Jounce Opt-Out, this Jounce Lead Co-Co Agreement shall remain in effect in perpetuity with respect to the United States.

8.2. Termination Without Cause.

8.2.1 Termination by Celgene for Convenience. At any time during the Jounce Co-Co Term, Celgene shall have the right, at its sole discretion, to terminate this Jounce Lead Co-Co Agreement in its entirety, upon [***] prior written notice to Jounce hereunder; it being understood and agreed that Celgene shall be entitled to terminate upon [***] written notice at any time it reasonably determines that such termination is necessary to comply with any Antitrust Law.

8.2.2 Termination by Celgene for Safety Reasons. Celgene shall have the right to terminate this Jounce Lead Co-Co Agreement immediately on a Co-Co Candidate-by-Co-Co Candidate basis upon written notice to Jounce based on Safety Reasons (defined below). Upon such termination for Safety Reasons, subject to the terms and conditions of this Jounce Lead Co-Co Agreement, Celgene shall be responsible, at its expense, for the wind-down, if any, of any Development of the applicable Co-Co Candidate, and corresponding Co-Co Product (including any Clinical Trials for the applicable Co-Co Candidate or Co-Co Product being conducted by or on behalf of Celgene and any regulatory costs for closing out corresponding regulatory activities) and any Commercialization activities for the applicable Co-Co Candidate or Co-Co Product. Such termination shall become effective upon the date that the Parties agree in writing that such wind-down is complete. Upon such termination for Safety Reasons, all licenses granted by

Jounce to Celgene under this Jounce Lead Co-Co Agreement shall terminate solely with respect to the applicable Co-Co Candidate or Co-Co Product. For purposes of this Jounce Lead Co-Co Agreement, “Safety Reason” means that the Data Safety Monitoring Board for a Clinical Trial, or the Parties by mutual written agreement, based upon additional information that becomes available or an analysis of then-existing information at any time, determines that Development or Commercialization, as applicable, of the Co-Co Candidate and/or Co-Co Products should be discontinued because the medical risk/benefit of the Co-Co Candidate or Co-Co Products is sufficiently unfavorable as to be incompatible with the welfare of patients to Develop or Commercialize or to continue to Develop or Commercialize it. If this Jounce Lead Co-Co Agreement is terminated pursuant to this Section 8.2.2, then subject to applicable data privacy laws, and on Jounce’s request, Celgene shall provide Jounce with full access to all relevant data relating to the terminated Co-Co Product.

8.3. Termination for Breach.

8.3.1 Termination by Either Party for Breach. Subject to certain variations set forth in Section 8.3.2 with respect to a material breach by either Party of its obligations to use Commercially Reasonable Efforts pursuant to Section 2.2.2, this Jounce Lead Co-Co Agreement and the rights granted herein may be terminated by either Party for the material breach by the other Party of this Jounce Lead Co-Co Agreement, provided, that if the breaching Party has not cured such breach within [***] (or [***], in the case of Celgene’s payment obligations under this Jounce Lead Co-Co Agreement or the time period provided in Section 8.3.2 with respect to a material breach by either Party of its obligation to use Commercially Reasonable Efforts, each as applicable) (the “Cure Period”) after the date of written notice to the breaching Party of such breach, which notice shall describe such breach in reasonable detail and shall state the non-breaching Party’s intention to terminate this Jounce Lead Co-Co Agreement pursuant to this Section 8.3.1. Notwithstanding the preceding sentence, the Cure Period for any allegation made in good faith as to a material breach under this Jounce Lead Co-Co Agreement will run from the date that written notice was first provided to the breaching Party by the non-breaching Party in accordance with Section 12.2 of the Master Collaboration Agreement. Any such termination of this Jounce Lead Co-Co Agreement under this Section 8.3.1 shall become effective at the end of the Cure Period, unless the breaching Party has cured any such breach or default prior to the expiration of such Cure Period, or, if such breach is not susceptible to cure within the Cure Period, then, the non-breaching Party’s right of termination shall be suspended only if and for so long as the breaching Party has provided to the non-breaching Party a written plan that is reasonably calculated to effect a cure and such plan is acceptable to the non-breaching Party, and the breaching Party commits to and carries out such plan as provided to the non-breaching Party. The Parties understand and agree that the totality of this Jounce Lead Co-Co Agreement and the totality of the circumstances with respect to this Jounce Lead Co-Co Agreement will be taken into account and assessed as a whole for purposes of determining whether a breach is material under this Jounce Lead Co-Co Agreement.

which notice shall be labeled as a “notice of material breach for failure to use Commercially Reasonable Efforts,” and shall state the reasons and justification for such termination and recommending steps which such Party believes the other Party should take to cure such alleged breach. For any such notice of breach by a Party, the Cure Period shall be [***], and shall become effective in accordance with Section 8.3.1.

8.3.4 Payments. No milestone payments by Celgene as set forth in Exhibit C-1 or Exhibit C-2, as applicable, will be due on milestones achieved during the period between the delivery to Jounce in accordance with Section 12.2 of the Master Collaboration Agreement of a notice of termination by Celgene under Section 8.3.1 or 8.3.2 and the effective date of termination; provided, however, if either Party provides notice of a dispute pursuant to Section 8.3.3 or otherwise and such dispute is resolved in a manner in which no termination of this Jounce Lead Co-Co Agreement occurs with respect to such breach or the breaching Party cures the applicable breach during the Cure Period, then upon such resolution or cure Celgene will within [***] pay to Jounce the applicable milestone payment for each milestone achieved during the period between the notice of termination under Section 8.3.1 or 8.3.2 and the resolution of such dispute or cure of such breach, and if it was determined that Celgene wrongly asserted breach by Jounce under Section 8.3.1, then Celgene shall also pay interest on such amount at an annual rate equal to the lesser of: (a) [***] above the prime rate as published by Citibank, N.A., New York, New York, or any successor thereto, at 12:01 a.m. on the first day of each Calendar Quarter in which such payments are overdue or (b) the maximum rate permitted by applicable Law; in each case calculated on the number of days such payment is withheld, compounded monthly.

8.4. Termination for Bankruptcy. If either Party makes a general assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not dismissed, discharged, bonded or stayed within [***] after the filing thereof, the other Party may terminate this Jounce Lead Co-Co Agreement in its entirety effective immediately upon written notice to such Party. In connection therewith, the provisions of Section 6.1.5 shall apply.

8.5. Termination for Patent Challenges. Either Party shall have the right to terminate this Jounce Lead Co-Co Agreement solely on a Co-Co Product-by-Co-Co Product basis upon written notice in accordance with Section 12.2 of the Master Collaboration Agreement if the other Party or any Affiliate challenges the validity, scope or enforceability of or otherwise opposes any Patent (a) included in the Jounce Co-Co IP and that is licensed to Celgene

under this Jounce Lead Co-Co Agreement, or (b) included in the Celgene Patents that is licensed to Jounce under this Jounce Lead Co-Co Agreement (other than in either case as may be necessary or reasonably required to assert a cross-claim or a counter-claim or to respond to a court request or order or administrative law, request or order) it being understood and agreed that either Party’s right to terminate this Jounce Lead Co-Co Agreement under this Section 8.5 shall not apply to any actions undertaken by an Affiliate of the other Party (the “Challenging Party”) that first becomes such an Affiliate as a result of a Business Combination involving the Challenging Party, where such new Affiliate was undertaking any of the activities described in the foregoing clause prior to such Business Combination; provided that a Party’s right to terminate this Jounce Lead Co-Co Agreement under this Section 8.5 shall apply to actions undertaken by such new Affiliate if the Challenging Party is the acquiror in such Business Combination and such new Affiliate does not terminate or otherwise cease such challenge or opposition within [***] after the effective date of such Business Combination. For the avoidance of doubt, an action by a Party or any Affiliate (collectively the “Prosecuting Party”) in accordance with this Jounce Lead Co-Co Agreement and the Master Collaboration Agreement to amend claims within a pending patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application or in defense of a Third Party proceeding, or to make a negative determination of patentability of claims of a patent application of the other Party or to abandon a patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application in accordance with Section 6.3, shall not constitute a challenge under this Section 8.5.

8.6. Effects of Expiration or Termination.

8.6.1 License Upon Expiration. Upon expiration (but not upon earlier termination) of this Jounce Lead Co-Co Agreement in the ROW Territory (or any country(ies) therein), the license granted to Celgene in Section 6.1.1 shall, with respect to the ROW Territory (or such country(ies)), automatically convert to the applicable license set forth in Section 8.1.2.

8.6.2 Termination by Celgene Pursuant to Section 8.2, or by Jounce Pursuant to Section 8.3, 8.4, or 8.5. In the event this Jounce Lead Co-Co Agreement is terminated by Celgene pursuant to Section 8.2 or by Jounce pursuant to Section 8.3, 8.4, or 8.5, then notwithstanding anything contained in this Jounce Lead Co-Co Agreement to the contrary, upon the effective date of such termination:

(a) License Termination. All rights and licenses granted to Celgene under this Jounce Lead Co-Co Agreement shall terminate (i) in their entirety if pursuant to Section 8.2.1, and (ii) with respect to the corresponding Co-Co Candidate and Co-Co Product if pursuant to Section 8.2.2, Celgene shall cease any and all Development, and Commercialization activities with respect to all corresponding terminated Co-Co Products and the Co-Co Candidate (subject to its wind-down obligations in accordance with Section 8.2.2 and Section 8.6.3), and all rights in such terminated Co-Co Product and the Co-Co Candidate granted by Jounce to Celgene shall revert to Jounce pursuant to Section 8.7;

(b) Return of Confidential Information. Each Party shall return or destroy all Confidential Information of the other Party with respect to the terminated Co-Co Products and

(c) Reversion Product Obligations. In the event this Jounce Lead Co-Co Agreement is terminated by Celgene pursuant to Section 8.2 or by Jounce Pursuant to Section 8.3, 8.4, or 8.5 , then Celgene shall comply with Section 8.7.

8.6.3 Termination by Celgene Pursuant to Section 8.3, 8.4, or 8.5.

8.6.4 Wind-Down of Regulatory Activities. In the case of any termination of this Jounce Lead Co-Co Agreement, if any Clinical Trials (including any Jounce Co-Co Additional Studies) are then being conducted at the time of such termination with respect to any Co-Co Product, the Parties hereby agree (i) to reasonably cooperate in the completion of any such Clinical Trials (including any Jounce Co-Co Additional Studies), and (ii) notwithstanding anything to the contrary contained herein, to grant to the Party that retains global Commercialization rights to such Co-Co Product following such termination (A) free of charge, copies of and rights of reference to and use of all Co-Co Product Data that is Controlled by such Party and generated pursuant to such Clinical Trials (including any Jounce Co-Co Additional Studies) that are relevant to or necessary to address issues relating to: (1) the safety of such Co-Co Product in the Territory, including data that is related to adverse effects experienced with such Co-Co Product and/or (2) all activities relating to CMC regarding such Co-Co Product and in each of (1) and (2), that are required to be reported or made available to Regulatory Authorities in the Territory, when and as such data become available, and (B) copies of and rights of reference to and use of all Co-Co Product Data (other than the Co-Co Product Data referred to in subclause (A) above) that is Controlled by such Party and generated pursuant to such Clinical Trials (including any Jounce Co-Co Additional Studies) that are relevant to or

8.7. Jounce Reversion Products.

8.7.1 Reversion. If this Jounce Lead Co-Co Agreement terminates with respect to the Co-Co Candidate or a Co-Co Product, or in the entirety, except for any termination by Celgene pursuant to Section 8.3, 8.4 or 8.5, then all corresponding Co-Co Products and/or the Co-Co Candidate shall be deemed “Jounce Reversion Products”.

8.7.2 Reversion Royalty. If such Jounce Reversion Products is designated as such by reason of a termination under Section 8.7.1, Jounce shall reimburse Celgene’s (i) actual costs directly incurred in the conduct of activities under this Jounce Lead Co-Co Agreement with respect to such Jounce Reversion Product in the ROW Territory, and (ii) share of Celgene’s actual costs directly incurred in the conduct of activities under this Jounce Lead Co-Co Agreement with respect to such Jounce Reversion Product in the U.S. that were included in the Profit & Loss Share, in each case prior to the effective date of such termination (the “Full Amount”). Such payment shall be in the form of an annual royalty of [***] of Co-Co Annual Net Sales of the relevant Jounce Reversion Products (applied mutatis mutandis as if such sales were by Celgene), until such time as the Full Amount has been fully paid.

(e) with respect to any Co-Co Candidate or Co-Co Product that becomes a Jounce Reversion Product as a result of termination of this Jounce Lead Co-Co Agreement at a time during which Celgene is conducting a Clinical Trial for such Co-Co Candidate or Co-Co Product, Celgene will, as directed by Jounce, facilitate the transfer to Jounce of all filings, information, Materials and Third Party agreements necessary to enable Jounce to complete such Clinical Trial, at Celgene’s sole cost and expense, if such termination is pursuant to Sections 8.3 or 8.4 (in each case by Jounce), and otherwise at Jounce’s cost and expense;

(g) As and to the extent a Third Party is Manufacturing such Jounce Reversion Product, Celgene shall use reasonable efforts to assist in the transfer of such supply

arrangements to Jounce at Celgene’s sole cost and expense, if such termination is by Jounce pursuant to Sections 8.3 or 8.4, and otherwise at Jounce’s cost and expense;

(i) If Celgene has obtained a Third Party License with respect to such Jounce Reversion Product and Jounce is a sublicensee under such Third Party License, then Jounce shall be solely responsible for any fees, expenses, milestones, royalties and other payments associated with the exercise of any rights under such Third Party License to the extent due with respect to the practice by Jounce, its Affiliates or sublicensees of the technology covered by or rights licensed under such Third Party License. To the extent Celgene has obtained a Third Party License with respect to such Jounce Reversion Product and Jounce is not a sublicensee under such Third Party License, then Celgene shall (1) if permitted under such Third Party License, assign to Jounce such Third Party License or (2) if such assignment is not permitted under such Third Party License, then, to the extent Celgene is permitted to do so, grant Jounce a sublicense under such Third Party License; provided, in each case, Jounce shall be solely responsible for any fees, expenses, milestones, royalties and other payments associated with the assignment, sub license and/or exercise of any rights under such Third Party License to the extent due with respect to the practice by Jounce, its Affiliates or sublicensees of the technology covered by or rights licensed under such Third Party License.

8.8. Survival of Sublicensees. Notwithstanding the foregoing, termination of this Jounce Lead Co-Co Agreement shall be construed as a termination of any sublicense of any Sublicensee hereunder, provided however that such Sublicensee shall have the right to request that Jounce grants to such Sublicensee a direct license. Jounce shall not unreasonably withhold its consent to any such request.

8.9. Surviving Provisions.

8.9.1 Accrued Rights; Remedies. Termination, relinquishment or expiration of this Jounce Lead Co-Co Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination, relinquishment or expiration, including the payment obligations under Article 5 hereof, and any and all damages or remedies (whether in law or in equity) arising from any breach hereunder. Such termination, relinquishment or expiration shall not relieve any Party from obligations which are expressly indicated to survive termination of this Jounce Lead Co-Co Agreement.

are in addition to any other relief and remedies available to either Party under this Jounce Lead Co-Co Agreement and at applicable Law.

2.2.3 From and after the PD-1 Effective Date, Article 4 of the Master

Collaboration Agreement shall no longer apply with respect to this PD-1 License Agreement.

2.3 Development.

2.3.1 Joint Working Group.

(a) Establishment. Within [***] after the PD-1 Effective Date, the Parties shall establish a joint working group (the “JWG”) as more fully described in this Section 2.3.1(a). The JWG shall set the Guiding Principles as described in Section 2.3.1(c)(i) and shall have review and oversight responsibilities for the activities performed under this PD-1 License Agreement with respect to Licensed Products.

(b) Membership. The JWG shall be comprised of [***] representatives (or such other number of representatives as the Parties may mutually agree) from each of Celgene and Jounce. Each Party may replace any or all of its representatives on the JWG at any time upon written notice to the other.

(i) [***].

(ii) The JWG shall create the Development Plan for Monotherapy Products and related commercialization plan and commercialization budgets, which the Parties may mutually agree upon from time to time and shall have oversight over and serve as a forum for the coordination of the Parties’ Development and Commercialization activities with respect to Monotherapy Products and the resolution of disputes with respect to such Development and Commercialization, including as described in Section 2.10.1. Each Party agrees to keep the JWG informed of its progress and activities with respect to such Development and Commercialization Activities.

(iii) [***] shall be responsible for preparing and circulating minutes of each meeting of the JWG, setting forth, inter alia, an overview of the discussions at the meeting and a list of any actions, decisions or determinations approved by the JWG. Such minutes shall be effective only after such minutes have been approved by both Parties in writing.

The Parties’ respective Executive Officers shall meet within [***] after such matter is referred to them, and shall negotiate in good faith to resolve the matter. If the Executive Officers are unable to resolve the matter within [***], or such other longer time frame the Executive Officers may

otherwise agree upon, after the matter is referred to them in accordance with this Section 2.3.1(d), then: (i) [***].

(e) Authority. For purposes of clarity, the JWG shall not have any authority with respect to either Party’s Development of any Non-Collaboration Combination Product or Collaboration Combination Products, and in particular none of the Parties, alone, or the JWG shall have any power to amend, modify, interpret or waive the terms of this PD-1 License Agreement or any Co-Development & Co-Commercialization Agreement, or to alter, increase, expand or waive compliance by a Party with a Party’s obligations under this PD-1 License Agreement. In any case where a matter within the JWG’s authority arises, the JWG shall convene a meeting and consider such matter as soon as reasonably practicable, but in no event later than [***] after the matter is first brought to the JWG’s attention (or, if earlier, at the next regularly scheduled JWG meeting).

2.3.2 Development Plan.

(a) Scope and Preparation.

(i) Monotherapy Products. The Parties may discuss preparation of an initial global Development Plan for any Monotherapy Products prior to the initiation of Development of such Monotherapy Products, and if the Parties mutually agree, shall work together in good faith to prepare an initial global Development Plan for such Monotherapy Products.

(b) Updates. Following the initial preparation of the Development Plan as set forth in Section 2.3.2(a), the Parties will update any applicable Development Plan [***] in each Calendar Year during the PD-1 Term prior to the grant of Regulatory Approval for the applicable Licensed Products. In addition, either Party may reasonably request at any time that the other Party consider and approve other updates to the Development Plan for Development activities to support Regulatory Approval for any Additional Study that the Parties agree to conduct pursuant to Section 2.3.3.

2.3.3 New Clinical Trials and Other Studies. If, following the PD-1 Effective Date, a Party (the “Proposing Party”) wishes to conduct a Clinical Trial or other study for Monotherapy Products in the Territory not already included in a Development Plan (an “Additional Study”), then solely in the case of Development of Monotherapy Products: (A) the Proposing Party shall first provide the proposed trial design and protocol for such Additional Study to the other Party (the “Non-Proposing Party”) for review and approval as to the clinical and regulatory aspects of such Additional Study, and shall incorporate reasonable comments from the Non-Proposing Party into such Additional Study design and protocol, and (B) following such review, provide the final proposed design and projected costs of such Additional Study to the Non-Proposing Party; it being understood and agreed that (1) in the case of any Additional Studies involving a Collaboration Combination Product, the terms and conditions for such Additional Study under Section 2.3 of the applicable Co-Development & Co-Commercialization Agreement shall supersede the following provisions in this Section 2.3.3, and (2) in the case of any Monotherapy Product, then the Parties agree that neither Party shall be entitled to participate in or have any access to any of the efficacy data arising under such Additional Study (and, for the avoidance of doubt, the Parties understand and agree that neither Party shall be required to submit any proposed trial design, protocol or otherwise for any such Additional Study to the other Party), provided that each party shall have a right to access such data for safety reporting to applicable Regulatory Authorities. Subject to the preceding sentence, the following shall apply for Additional Studies hereunder:

Each Party shall treat the results of any such accountant’s review of the other Party’s records as Confidential Information of the non-requesting Party subject to the terms of Article 8 of the Master Collaboration Agreement. If any review reveals a deficiency or overpayment in the calculation and/or payment of royalties by a Party, then (a) the applicable

party shall promptly pay the other Party the amount remaining to be paid, and (b) if any such underpayment is by [***] or more in any Calendar Year, the non-requesting Party shall, within [***] of invoice therefor, pay the reasonable Direct Costs incurred by the requesting Party in connection with the review.

(c) Right to Participate; Joinder. The non-enforcing Party in relation to any enforcement action or proceeding set forth in Sections 4.5.2(a) and 4.5.2(b) will have the right, at its own expense and by counsel of its choice, to be represented in any such action or proceeding. In the case of any Licensed Enforcement Proceeding or Licensed Step-In Proceeding, at the enforcing Party’s written request, and at the enforcing Party’s expense (subject to Section 4.5.4), the other Party shall join any such action or proceeding as a party and will use Commercially Reasonable Efforts to cause any Third Party as necessary to join such action or proceeding as a party if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable Law to pursue such action or proceeding. All time periods set forth in this Section 4.5.2 shall be subject to applicable Law, which may prevent earlier enforcement.

(d) Cooperation. In addition to the obligations set forth in Section 4.5.2(a) through 4.5.2(c), each Party will provide to the Party enforcing any such rights under Section 4.5.2(a) or 4.5.2(b), as applicable, reasonable assistance and cooperation in such enforcement, at such enforcing Party’s request and expense (subject to Section 4.5.4). The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts. The Parties will coordinate any Licensed Enforcement Proceeding with respect to the Jounce Licensed Collaboration Patent and Celgene Patents. Each Party bringing any such action or proceeding in accordance with this Section 4.5 shall have an obligation to consult with the other Party and will take comments of such other Party into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any Jounce Licensed Collaboration Patent and Celgene Patent that is the subject of such proceeding.

(e) Agreement to Enforce. Notwithstanding anything to the contrary in this Section 4.5, if either Party has a reasonable, good faith concern that the other Party’s exercise of its backup enforcement or defense rights with respect to any Patent as set forth in Section 4.5.2(a) would be detrimental to the overall patent protection of the Licensed Products or related

Licensed Diagnostic Products, then such other Party shall not be permitted to enforce or defend such Patent without the prior consent of the objecting Party.

(f) Settlement. Notwithstanding anything to the contrary in this Section 4.5, a settlement or consent judgment or other voluntary final disposition of a suit under this Section 4.5 may be entered into without the consent of the Party not bringing suit; provided, however, that in any event, any such settlement, consent judgment or other disposition of any action or proceeding by a Party under this Article 4 shall not, without the consent of the Party not bringing suit, (a) impose any liability or obligation on the Party not bringing suit, (b) include the grant of any license, covenant or other rights to any Third Party that would conflict with or reduce the scope of the subject matter included under the licenses granted to the Party not bringing suit under this PD-1 License Agreement, (c) conflict with or reduce the scope of the subject matter claimed in any Patent owned by the Party not bringing suit, or (d) adversely affect the interest of the Party not bringing suit in any material respect, provided that such consent shall not be unreasonably withheld, conditioned or delayed.

(g) Costs of Enforcement. Except as otherwise set forth in this Section 4.5, each Party shall bear all of its own internal costs incurred in connection with its activities under this Section 4.5 that relate to a Licensed Enforcement Proceeding or a Licensed Step-In Proceeding relating to Jounce Licensed Patents or Celgene PD-1 Patents in the Territory, and, if a Party commences a Licensed Enforcement Proceeding or a Licensed Step-In Proceeding in the Territory, it shall bear all external costs and expenses for such action.

(h) Recoveries. Any damages or other monetary awards recovered in any action, suit or proceeding brought under this Section 4.5 shall be shared as follows:

(i) Initial Allocation. Such damages or other sums recovered shall first be applied to reimburse each Party for all of its Direct Costs incurred in connection with such action (including, for this purpose, a reasonable allocation of expenses of outside counsel), and if such recovery is insufficient to cover all such costs and expenses of both Parties, it shall be shared in proportion to the total of such costs and expenses incurred by each Party; and

(ii) Remaining Proceeds. Any remaining proceeds in case of suits with respect to a Licensed Enforcement Proceeding or a Licensed Step-In Proceeding relating to any Licensed Product or related Licensed Diagnostic Product under this Section 4.5, shall be retained by the Party bringing suit under this Section 4.5 or, if damages are recovered for infringement of both Jounce Licensed Collaboration Patents and Celgene PD-1 Patents, then such remaining proceeds shall be shared equally by the Parties.

4.6 Patent Term Extensions. In the course of conducting activities pursuant to this PD-1 License Agreement, Jounce and Celgene shall discuss and seek to reach mutual agreement as to which, if any, of the Patents within the Jounce Licensed Collaboration Patents or Celgene Patents that Cover the Licensed Candidate, or Licensed Products containing the Licensed Candidate, for which the Parties shall apply to obtain patent term extensions, adjustments, restorations, or supplementary protection certificates under applicable Laws, based on the best commercial interests of the Licensed Candidate or Licensed Products; it being understood and agreed that, (a) Celgene shall have final say with respect to such actions in the ROW Territory and if Celgene seeks a patent term extension in the ROW Territory, then Jounce agrees to

negotiate in good faith with respect to any measures required by applicable Law for Celgene to obtain such extension and (b) Jounce shall have final say with respect to such actions in the U.S. and if Jounce seeks a patent term extension in the U.S., then Celgene agrees to negotiate in good faith with respect to any measures required by applicable Law for Jounce to obtain such extension.

4.7 Third Party Licenses. If, at any time during the PD-1 Term, either Party reasonably determines that any Third Party intellectual property rights may be necessary for the Development, Manufacture or Commercialization of any Licensed Product or Licensed Candidate, that is the subject of research, Development, Manufacture and/or Commercialization efforts under this PD-1 License Agreement, then such Party will notify the other Party promptly, and Section 7.9.2 of the Master Collaboration Agreement shall apply and, if the Parties agree to obtain a license under such Third Party intellectual property that enables each Party to Develop, Manufacture and Commercialize any Licensed Candidate, Licensed Product or Licensed Diagnostic Product in the Territory, then the Parties shall share equally in the costs of such license; provided, however, that notwithstanding anything to the contrary in the Master Collaboration Agreement, the Parties shall cooperate through the Patent Committee regarding determining which Party should obtain a license, provided, further that unless the Parties otherwise agree, the following shall apply: (a) Jounce shall have the sole right, but not the obligation, to obtain a license from a Third Party under intellectual property rights that may be necessary for such activities with respect to any Licensed Product that is being Manufactured by or on behalf of Jounce anywhere in the Territory, with respect to such Manufacturing; and (b) Celgene shall have the sole right, but not the obligation, to obtain a license from a Third Party under intellectual property rights that may be necessary for such activities with respect to any Licensed Product that is being Manufactured by or on behalf of Celgene anywhere in the Territory, with respect to such Manufacturing.

ARTICLE 5
INDEMNIFICATION; INSURANCE

5.1 Indemnification by Celgene. Celgene shall indemnify, defend and hold harmless the Jounce Indemnitees, from and against any and all Third Party Damages to the extent arising out of or relating to, directly or indirectly, from any Claim based upon:

5.1.1 the [***] under this PD-1 License Agreement;

5.1.2 any [***] under this PD-1 License Agreement;

5.1.3 any [***] under this PD-1 License Agreement; or

5.1.4 any [***];

5.1.5 [***].

5.2 Indemnification by Jounce. Jounce shall indemnify, defend and hold harmless the Celgene Indemnitees, from and against any and all Third Party Damages to the extent arising out of or relating to, directly or indirectly, from any Claim, based upon:

5.2.1 the [***] under this PD-1 License Agreement; or

5.2.2 any [***] under this PD-1 License Agreement;

5.2.3 any [***] under this PD-1 License Agreement; or

5.2.4 [***].

5.3 Notice of Claims. A Claim to which indemnification applies under Section 5.1 or Section 5.2 shall be referred to herein as an “Indemnification Claim.” If the Indemnitee intends to claim indemnification under this Article 5, the Party claiming indemnification (the “Indemnitee”) shall notify the indemnifying Party (the “Indemnitor”) in writing, promptly upon becoming aware of an Indemnification Claim, describing in reasonable detail the facts giving rise to the Indemnification Claim; provided, that an Indemnification Claim in respect of any action at law or suit in equity by or against a Third Party as to which indemnification shall be sought shall be given promptly after the action or suit is commenced (provided that the Indemnitee is aware of such commencement); and provided further, that the failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this PD-1 License Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice.

5.4 Indemnification Procedures. If an Indemnitee receives written notice of a Claim that the Indemnitee believes may result in a claim for indemnification under this Article 5, such Indemnitee shall deliver an Indemnification Claim to the Indemnitor in accordance with the provisions of Section 5.3. If the Litigation Conditions are satisfied, then the Indemnitor shall have the right to assume and control the defense of the Claim, at its own expense with counsel selected by it and reasonably acceptable to the Indemnitee, by delivering written notice of its assumption of such defense to the Indemnitee within [***] of its receipt of notice of such Claim from the Indemnitor (but the Indemnitor shall in any event have the right to assume and control the defense of a Claim that initially sought injunctive relief (including a declaratory judgment) from the Indemnitee when the only remaining dispute in such matter is the determination of non-injunctive relief or when the only remaining relief sought by the Third Party in such matter is non-injunctive relief, whichever is first); provided, however, that the Indemnitee shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the Indemnitor, if (a) representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflict of interests between such Indemnitee and Indemnitor, (b) the Indemnitor has failed within a reasonable time to retain counsel, (c) the Indemnitee shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnitor, or (d) at any time the Litigation Conditions are not satisfied with respect to such Claim. If the Indemnitor assumes and controls the defense of such Claim, the Indemnitor shall keep the Indemnitee reasonably apprised of the status of the Claim and the Indemnitee shall be entitled to otherwise monitor such Claim at its sole cost and expense. If the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee or if the Indemnitor does not assume the defense of the Claim as

described in this Section 5.4, the Indemnitee shall be permitted to assume and control the defense of such Claim (but shall have no obligation to do so) and in such event shall be entitled to settle or compromise the Indemnification Claims in its sole and reasonable discretion, provided that if the Indemnitee is entitled to assume the defense of the Claim pursuant to this Section 5.4 solely because the Claim seeks injunctive relief (including a declaratory judgment) against or from the Indemnitee, then the Indemnitee shall not settle or compromise such Indemnification Claims in any manner that involves the payment of monetary damages or has an adverse effect on the Indemnitor’s rights or interests (including any rights under this PD-1 License Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this PD-1 License Agreement, any other Co-Development & Co-Commercialization Agreement or the Master Collaboration Agreement) without the prior written consent of the Indemnitor, which consent the Indemnitor shall not unreasonably withhold, condition or delay. If the Indemnitor has assumed and controls the defense of the Claim in accordance with this Section 5.4, (i) the Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld, conditioned or delayed and (ii) the Indemnitor shall not settle or compromise the Indemnification Claim in any manner that would result in the payment of amounts by the Indemnitee, impose any other obligation on the Indemnitee or otherwise have an adverse effect on the Indemnitee’s rights or interests (including any rights under this PD-1 License Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this PD-1 License Agreement or any other Co-Development & Co-Commercialization Agreement, or the Master Collaboration Agreement), without the prior written consent of the Indemnitee. In each case, the Party that is not controlling the defense of any Claim shall reasonably cooperate with the Party that is controlling the defense of such Claim, at the non-controlling Party’s expense and shall make available to the controlling Party all pertinent information under the control of the non-controlling Party, which information shall be subject to Article 8 of the Master Collaboration Agreement. Each Party shall use commercially reasonable efforts to avoid production of Confidential Information of the other Party (consistent with applicable Law and rules of procedure), and to cause all communications among employees, counsel and other representatives of such Party to be made so as to preserve any applicable attorney-client or work-product privileges.

5.5 Insurance. Each Party shall maintain, at its cost, a program of insurance and/or self-insurance against liability (including product liability insurance) and other risks associated with its activities and obligations under this PD-1 License Agreement, including as applicable its Clinical Trials, the Commercialization of any Licensed Candidate, and its indemnification obligations hereunder, in such amounts, subject to such deductibles and on such terms as are customary for such Party for the activities to be conducted by it under this PD-1 License Agreement.

5.6 LIMITATION OF LIABILITY. EXCEPT (A) FOR A BREACH OF SECTION 7.4 OR (B) FOR CLAIMS THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 5 OR (C) FOR DAMAGES DUE TO THE FRAUD, MALICIOUS ACTIONS AND/OR INTENTIONAL TORT OF THE LIABLE PARTY, NEITHER JOUNCE NOR CELGENE, NOR ANY OF THEIR RESPECTIVE AFFILIATES WILL BE LIABLE TO THE OTHER PARTY TO THIS PD-1 LICENSE AGREEMENT OR ITS AFFILIATES

UNDER THIS PD-1 LICENSE AGREEMENT FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR PUNITIVE OR EXEMPLARY DAMAGES OR LOST PROFITS OR LOST DATA, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

ARTICLE 6
PD-1 TERM AND TERMINATION

6.1 PD-1 Term; Expiration. This PD-1 License Agreement shall become effective on the PD-1 Effective Date and, unless terminated pursuant to this Article 6, shall remain in effect until the later to occur of (a) the date there is no longer a Valid Claim in the Jounce Licensed Collaboration Patents or the Celgene PD-1 Patents that Cover a Licensed Product, (b) [***] following First Licensed Sale of the Licensed Product, or (c) the [***] of the PD-1 Effective Date (the “PD-1 Term”).

6.2 Termination Without Cause.

6.2.1 Termination by Celgene for Convenience. At any time during the PD-1 Term, Celgene shall have the right, at its sole discretion, to terminate this PD-1 License Agreement in its entirety, upon [***] prior written notice to Jounce hereunder; it being understood and agreed that Celgene shall be entitled to terminate upon [***]’ written notice at any time it reasonably determines that such termination is necessary to comply with any Antitrust Law.

6.2.2 Termination by Celgene for Safety Reasons. Celgene shall have the right to terminate this PD-1 License Agreement immediately on a Licensed Candidate-by-Licensed Candidate basis upon written notice to Jounce based on Safety Reasons (defined below). Upon such termination for Safety Reasons, subject to the terms and conditions of this PD-1 License Agreement, Celgene shall be responsible, at its expense, for the wind-down, if any, of any Development of the applicable Licensed Candidate, and corresponding Licensed Product (including any Clinical Trials for the applicable Licensed Candidate or Licensed Product being conducted by or on behalf of Celgene and any regulatory costs for closing out corresponding regulatory activities) and any Commercialization activities for the applicable Licensed Candidate or Licensed Product. Such termination shall become effective upon the date that the Parties agree in writing that such wind-down is complete. Upon such termination for Safety Reasons, all licenses granted by Jounce to Celgene under this PD-1 License Agreement shall terminate solely with respect to the applicable Licensed Candidate or Licensed Product. For purposes of this PD-1 License Agreement, “Safety Reason” means that the Data Safety Monitoring Board for a Clinical Trial, or the Parties by mutual written agreement, based upon additional information that becomes available or an analysis of then-existing information at any time, determines that Development or Commercialization, as applicable, of the Licensed Candidate and/or Licensed Products should be discontinued because the medical risk/benefit of the Licensed Candidate or Licensed Products is sufficiently unfavorable as to be incompatible with the welfare of patients to Develop or Commercialize or to continue to Develop or Commercialize

it. If this PD-1 License Agreement is terminated pursuant to this Section 6.2.2, then subject to applicable data privacy laws, and on Jounce’s request, Celgene shall provide Jounce with full access to all relevant data relating to the terminated Licensed Product.

6.3 Termination for Breach. This PD-1 License Agreement and the rights granted herein may be terminated by either Party for the material breach by the other Party of this PD-1 License Agreement, provided, that if the breaching Party has not cured such breach within [***]s (or [***], in the case of Celgene’s payment obligations under this PD-1 License Agreement with respect to a material breach by either Party of its obligation to use Commercially Reasonable Efforts, each as applicable) (the “Cure Period”) after the date of written notice to the breaching Party of such breach, which notice shall describe such breach in reasonable detail and shall state the non-breaching Party’s intention to terminate this PD-1 License Agreement pursuant to this Section 6.3. Notwithstanding the preceding sentence, the Cure Period for any allegation made in good faith as to a material breach under this PD-1 License Agreement will run from the date that written notice was first provided to the breaching Party by the non-breaching Party in accordance with Section 12.2 of the Master Collaboration Agreement. Any such termination of this PD-1 License Agreement under this Section 6.3 shall become effective at the end of the Cure Period, unless the breaching Party has cured any such breach or default prior to the expiration of such Cure Period, or, if such breach is not susceptible to cure within the Cure Period, then, the non-breaching Party’s right of termination shall be suspended only if and for so long as the breaching Party has provided to the non-breaching Party a written plan that is reasonably calculated to effect a cure and such plan is acceptable to the non-breaching Party, and the breaching Party commits to and carries out such plan as provided to the non-breaching Party. The Parties understand and agree that the totality of this PD-1 License Agreement and the totality of the circumstances with respect to this PD-1 License Agreement will be taken into account and assessed as a whole for purposes of determining whether a breach is material under this PD-1 License Agreement.

6.4 Termination for Bankruptcy . If either Party makes a general assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not dismissed, discharged, bonded or stayed within [***] after the filing thereof, the other Party may terminate this PD-1 License Agreement in its entirety effective immediately upon written notice to such Party. In connection therewith, the provisions of Section 4.1.5 shall apply.

6.5 Termination for Patent Challenges. Either Party shall have the right to terminate this PD-1 License Agreement upon written notice in accordance with Section 12.2 of the Master Collaboration Agreement if the other Party or any Affiliate challenges the validity, scope or enforceability of or otherwise opposes any Patent (a) included in the Jounce Licensed IP and that is licensed to Celgene under this PD-1 License Agreement, or (b) included in the Celgene Patents that is licensed to Jounce under this PD-1 License Agreement (other than in either case as may be necessary or reasonably required to assert a cross-claim or a counter-claim or to respond to a court request or order or administrative law, request or order) it being understood and agreed that either Party’s right to terminate this PD-1 License Agreement under this Section 6.5 shall not apply to any actions undertaken by an Affiliate of the other Party (the “Challenging Party”) that first becomes such an Affiliate as a result of a Business Combination

involving the Challenging Party, where such new Affiliate was undertaking any of the activities described in the foregoing clause prior to such Business Combination; provided that a Party’s right to terminate this PD-1 License Agreement under this Section 6.5 shall apply to actions undertaken by such new Affiliate if the Challenging Party is the acquiror in such Business Combination and such new Affiliate does not terminate or otherwise cease such challenge or opposition within [***] after the effective date of such Business Combination. For the avoidance of doubt, an action by a Party or any Affiliate (collectively the “Prosecuting Party”) in accordance with this PD-1 License Agreement and the Master Collaboration Agreement to amend claims within a pending patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application or in defense of a Third Party proceeding, or to make a negative determination of patentability of claims of a patent application of the other Party or to abandon a patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application in accordance with Section 4.3, shall not constitute a challenge under this Section 6.5.

6.6 Effects of Expiration or Termination.

6.6.1 Licenses Upon Expiration. Upon expiration (but not upon earlier termination) of this PD-1 License Agreement in the Territory (or any country(ies) therein), the licenses granted under Section 4.1.1 and Section 4.1.2 shall, with respect to the Territory (or such country(ies)), become worldwide, non-exclusive, fully paid-up, royalty-free, sublicensable (through multiple tiers), irrevocable and non-terminable.

EXHIBIT E

PD-1 Profit & Loss Share

This Exhibit E to this PD-1 License Agreement covers financial planning, accounting policies and procedures to be followed in determining the PD-1 Profit & Loss Share for Monotherapy Products and any other Licensed Products which are not co-packaged or co-formulated (excluding, for the avoidance of doubt, any co-formulated or co-packaged Collaboration Combination Products or Non-Collaboration Combination Products, the “Revenue Split Products”). The PD-1 Profit & Loss Share is not a legal entity and has been defined for identification purposes only.

1. Principles of Reporting.

The presentation of results of operation of the Parties with respect to Revenue Split Products will be based on each Party’s respective financial information presented separately and on a consolidated basis in the reporting format depicted as follows:

	[]*	[]*

[***]

[***]

[***]

[***]

It is the intention of the Parties to interpret definitions to be consistent with this Exhibit E and Accounting Principles, it being understood and agreed that [***]. Where such costs will be determined based on either Party’s system of cost or project accounting, each Party agrees to provide reasonable supporting documentation, as may be requested by the other Party, to ensure that each Party’s methodologies are reasonable and consistently applied. To the extent that such costs are not readily determinable based on the respective Party’s system of cost or project accounting, the JWG will develop a reasonable methodology for determining such costs. Reasonable methodologies may include a standard rate or some other appropriate basis for allocating costs. For billing and reporting, the statement of operations will be translated into U.S. Dollars in accordance with this PD-1 License Agreement.

If necessary, a Party will make the appropriate adjustments to the financial information it supplies under this Exhibit E to conform to the above format of reporting results of operation.

The Parties agree that (a) all Revenue Split Products will be booked by the Party which is then-Commercializing such Revenue Split Product and (b) all Collaboration Combination Products will be booked pursuant to the terms of the applicable Co-Development &

E - 1

Co-Commercialization Agreement pursuant to which such Collaboration Combination Product is then-being Commercialized.

2. Frequency of Reporting. Solely with respect to Revenue Split Products:

a. The fiscal year for the purposes of reporting and other activities undertaken by the Parties pursuant to this Exhibit E will be a Calendar Year. Unless the schedule of such reporting is altered by the JWG, reporting by each Party for revenues and expenses will be as set forth in this Paragraph 2 of this Exhibit E.

b. The Party Commercializing such Revenue Split Product will prepare a consolidated reporting of the activities undertaken by the Parties hereunder (including Gross Profit or Loss), the calculation of the Gross Profit or Loss sharing, and determination of the cash settlement as between the Parties. The Party Commercializing such Revenue Split Product will provide the other Party within [***] after the end of each Calendar Quarter, a detailed statement showing the consolidated results and calculations of the Gross Profit or Loss sharing and cash settlement required in a format agreed to by the Parties (the “Report”). The non-Commercializing Party will cooperate as appropriate and provide the Commercializing Party with financial statements, within [***] of the end of each Calendar Quarter, for the non-Commercializing Party’s activities with respect to Revenue Split Product (if any), prepared in accordance with the terms contained in the financial planning, accounting and reporting procedures set forth in this Exhibit E in order for the Commercializing Party to prepare the consolidated reports, including in reasonable detail the Cost of Goods Sold in such Calendar Quarter.

c. On a monthly basis, the Commercializing Party will supply the non- Commercializing Party with an estimate of Revenue Split Product Annual Net Sales during the prior month of such Revenue Split Product and related Licensed Diagnostic Product, in units, local currency and U.S. dollars (using the conversion method set forth in this PD-1 License Agreement) according to the Commercializing Party’s sales reporting system, which will be consistent with the financial planning, accounting and reporting procedures set forth in this Exhibit E. Each such report will be provided as early as possible, but no later than [***] after the last day of the month in question, and will separately provide monthly and year-to-date cumulative figures. The Commercializing Party will provide to the non- Commercializing Party, together with the next monthly estimate under this Section 2(c), an updated report for the immediately preceding month providing a reconciliation of the estimated amounts for such preceding month against the actual Revenue Split Product Annual Net Sales during such month of such Revenue Split Product and Licensed Diagnostic Product in the United States.

3. Financial Records. With respect to all financial records and reports required by this Exhibit E, each Party to the extent applicable hereunder will keep financial records in accordance with its Accounting Principles. All cost reporting will be based on the appropriate costs definitions stated in this Exhibit E or elsewhere in this PD-1 License

E - 2

Agreement, and each Party will report costs in a manner consistent with a mutually agreed standard.

4. Gross Profits and Loss Sharing.

a. The Parties agree to share Gross Profits or Losses with respect to Development and Commercialization of Revenue Split Products in the Territory as set forth below:

i. Celgene will bear (and be entitled to) fifty percent (50%), and Jounce will bear (and be entitled to) fifty percent (50%) of Gross Profits or Losses.

b. Jounce shall either invoice Celgene, or pay to Celgene, at the time the Report is delivered to Celgene, an amount such that Celgene will be bearing its portion of the PD-1 Profit & Loss Share for the relevant sales of Revenue Split Product and related Licensed Diagnostic Product. Either (i) Celgene shall make payment in full to Jounce of the amount of any such invoice, within [***] after the date of such invoice, or (ii) Jounce shall pay Celgene within [***] after the Report is delivered to Celgene, an amount such that Celgene will bear or receive its portion of the PD-1 Profit & Loss Share. Such amounts will be invoiced and paid (whether before or after Regulatory Approval is received) pursuant to this Paragraph 4(b) of this Exhibit E. All payments to be made by either Party hereunder will be made in U.S. Dollars by wire transfer to such bank account as such Party may designate. Jounce shall have the right to request deferral of Jounce’s obligation to pay amounts such that Celgene bears its portion of the PD-1 Profit & Loss Share for the relevant sales of Revenue Split Product and related Licensed Diagnostic Product as described in Exhibit G of the Master Collaboration Agreement.

c. In the event any payment is made after the date specified in Paragraph 4(b) of this Exhibit E and provided that such payment is not otherwise subject to good faith dispute, the paying Party will pay the additional amounts or the receiving Party will reimburse such excess payments, with interest from the date originally due as provided in Section 3.2.3 of this PD-1 License Agreement.

5. Start of Operations and Effective Accounting Date Termination.

a. Operation of the PD-1 Profit & Loss Share will be deemed to have commenced as of the PD-1 Effective Date. Except as otherwise provided herein, costs and expenses incurred prior to such date are not chargeable to the Profit & Loss Share.

b. Unless otherwise set forth in this PD-1 License Agreement, for reporting and accounting purposes with respect to the PD-1 Profit & Loss Share, the effective termination date of the PD-1 License Agreement with regard to the last detailing year for Revenue Split Product and related Licensed Diagnostic Product will be the end of the month in which such termination takes place.

E - 3

6. Audits. Each Party will keep, and will cause its Affiliates and Sublicensees, as applicable, to keep, accurate books and records of accounting as required under its Accounting Principles for the purpose of calculating all amounts payable by either Party to the other Party under the PD-1 Profit & Loss Share. Such records shall be retained by each Party or any of its Affiliates or Sublicensees (in such capacity, the “Recording Party”) for a period of no less than [***] after the Calendar Year to which such records relate. At the request of either Party, the other Party will, and, will cause its Affiliates and Sublicensees, as applicable, to, permit the requesting Party and its representatives (including an independent auditor), at reasonable times and upon reasonable notice to the Recording Party, to inspect, review and audit the books and records maintained pursuant to this Paragraph 6 of this Exhibit E. Such examinations may not, unless otherwise required by applicable Law, (a) be conducted for any Calendar Year more than [***] after the end of such Calendar Year, (b) be conducted more than once in any [***] period, or (c) be repeated for any Calendar Year. Except as provided below, the cost of this examination will be borne by the Party that requested the examination, unless the audit reveals a variance of more than [***] from the reported amounts, in which case the audited Party will bear the cost of the audit. Unless disputed as described below, if such audit concludes that additional payments were owed or that excess payments were made during such period, the paying Party will pay the additional amounts or the receiving Party will reimburse such excess payments, with interest from the date originally due as provided in Section 3.2.3 of this PD-1 License Agreement, within [***] after the date on which a written report of such audit is delivered to the Parties. In the event of a dispute regarding such books and records, including the amounts owed to a Party under Article 3 of this PD-1 License Agreement, Revenue Split Product Annual Net Sales of Revenue Split Product and related Licensed Diagnostic Product or Gross Profit, the Parties will work in good faith to resolve the disagreement. If the Parties are unable to reach a mutually acceptable resolution of any such dispute within [***], such dispute will be resolved in accordance with Section 12.7 of the Master Collaboration Agreement. The receiving Party will treat all information subject to review under this Paragraph 6 of this Exhibit E in accordance with the confidentiality provisions of Article 8 of the Master Collaboration Agreement and the Parties will cause any auditor or arbitrator to enter into a reasonably acceptable confidentiality agreement with the audited Party obligating such firm to retain all such financial information in confidence pursuant to a confidentiality agreement.
