If no royalty is payable on a given unit of Licensed Product (e.g., following the Royalty Term for such Licensed Product in a given country), then the Net Sales of such unit

of Licensed Product will not be included for purposes of determining the royalties or royalty tiers, Net Sales of a given Licensed Product will not be combined with Net Sales of any other Licensed Product for purposes of determining the foregoing royalties or royalty tiers.

(b)    Offset for Third Party Payments. If a Selling Party obtains a right or license under any Patent, Know-How, or other intellectual property right of a Third Party after the Effective Date, where the Development, Manufacturing, or Commercialization of any Licensed Product by or on behalf of a Selling Party would result in a payment to such Third Party, then, subject to Section 8.5.3(e), Gilead may deduct from the royalty payments that would otherwise have been due under Section 8.5.1 and the milestone payments that would otherwise have been due under Section 8.4.1 with respect to Annual Net Sales in a particular Calendar Quarter, an amount equal to [***] percent ([***]%) of the amount of any payments (including [***]) paid or accrued by a Selling Party to such Third Party for such right or license or the exercise thereof during such Calendar Quarter.

(c)    Offsets for Certain [***] Costs. In addition to the deductions permitted under Section 8.5.3(b), Gilead may deduct from the milestone payments that would otherwise have been due under Section 8.3.1, the milestone payments that would otherwise have been due under Section 8.4.1, and the royalty payments that would otherwise have been due under Section 8.5.1 with respect to Annual Net Sales in a particular Calendar Quarter, an amount equal to [***] percent ([***]%) of the amount of [***] and, as applicable, other [***] actually incurred by or on behalf of Gilead [***], in each case excluding any such costs and expenses previously recovered by Gilead pursuant to Section 10.6.

respect to Annual Net Sales in a particular Calendar Quarter, an amount equal to the payments [***] to the relevant [***] or [***] counterparty or counterparties, as applicable, under the relevant [***] or [***] during such Calendar Quarter; provided that under no circumstance may Gilead deduct an amount under this Section 8.5.3(d) that exceeds [***] with respect to any payments paid or accrued under the relevant [***] or [***].

(e)    Royalty Floor. Without limiting the provisions of Section 15.6, in no event will the royalty reductions or royalty offset rights described in Section 8.5.3(a), Section 8.5.3(b), or Section 8.5.3(c), alone or together, reduce the royalties payable by Gilead for a given Calendar Quarter to less than [***] percent ([***]%) of the amounts payable by Gilead for a given Calendar Quarter pursuant to Section 8.5.1 (without the application of Section 8.5.3(a), Section 8.5.3(b) and Section 8.5.3(c)). Subject to the previous sentence, Gilead may [***] any such royalty reductions or offset rights, which [***] a Calendar Quarter [***] such Calendar Quarter, [***] to such royalties [***] and [***] on a Calendar Quarterly basis thereafter.

8.5.4    Payment of Royalties.

The Payor shall have the right to deduct any such tax, levy, or charge actually paid from payment due to the Payee. For

the avoidance of doubt, the Payor’s remittance of such withheld taxes, together with payment to the Payee of the remaining payment, will constitute the Payor’s full satisfaction of payments due under this Article 8.

(c)    Transfer Taxes. Unless otherwise agreed by the Parties in writing, the amounts payable under this Agreement are exclusive of all applicable sales or use, goods and services, value added, consumption or other similar fees or taxes (“Transfer Taxes”).

Subject to the other terms of this Section 8.7.2, during the Term and for a period of [***] years thereafter, at the request of Jounce, which will not be made more frequently than [***] per Calendar Year [***], upon at least [***] days’ prior written notice from Jounce, and at the expense of Jounce, Gilead will permit an independent, nationally-recognized certified public accountant selected by Jounce and reasonably acceptable to Gilead (each, an “Auditor”) to inspect, during regular business hours, the relevant records required to be maintained by Gilead under Section 8.7.1; provided, that such audit right will not apply to records beyond [***] years from the Calendar Quarter of the audit request and all periods are subject to audit only once. Prior to its inspection, the Auditor will enter into a confidentiality agreement with both Parties having obligations of confidentiality and non-use no less restrictive than those set forth in Article 12 and limiting the disclosure and use of such information by the Auditor to authorized representatives of the Parties and the purposes germane to Section 8.7.1. The Auditor will report to Jounce only whether the particular amount being audited was accurate and, if not, the amount of and reason for any discrepancy, and the Auditor will not report any

other information to Jounce. Jounce will treat the results of any Auditor’s review of Gilead’s records as Confidential Information of Gilead subject to the terms of Article 12. Notwithstanding the foregoing, Jounce may disclose such conclusions of the Auditor to the [***] Agreement counterparties, to the extent required under the relevant [***] Agreement, provided that such conclusions shall be subject to a binding confidentiality agreement acceptable to Gilead. In the event such audit leads to the discovery of a discrepancy to Jounce’s detriment, Gilead will, within [***] days after receipt of such report from the Auditor, pay any undisputed amount of the discrepancy. Jounce will pay the full cost of the audit unless the underpayment of amounts due by Gilead is greater than [***] percent ([***]%) of the amount due for the entire period being examined, in which case Gilead will pay the reasonable cost charged by the Auditor for such review.

10.3.2    Absent a claim of Third Party Infringement under Section 10.5, Gilead will have the first right, but not obligation, to undertake proceedings to proactively invalidate Third Party Patents (e.g., through oppositions, post grant review, inter partes review, derivations, re-examinations, post-grant proceedings, and other similar proceedings) that Gilead at its sole discretion deems a risk to the commercialization of the Licensed Products (“Proactive Defense Proceedings”). Gilead will [***] of such Proactive Defense Proceedings. Notwithstanding the foregoing, the Parties agree and acknowledge that prior to the Effective Date, [***] (the “[***]”), and Jounce and Gilead will [***] with respect to this [***].

10.4    Enforcement.

10.4.1    Each Party will promptly notify the other Party if it becomes aware of infringement or Patent challenge by a Third Party of any Jounce Patent or any Joint Patent in the Territory, including any declaratory judgment, opposition, post grant review, inter partes review, or similar action alleging the invalidity, unenforceability, unpatentability, or non-infringement with respect to such Jounce Patent, including under the BPCIA or the United States Patient Protection and Affordable Care Act of 2010 (Pub. L. No. 111-48) or their successor provisions, any regulatory filing based on Section 351(k) of the Public Health Service Act (42 U.S.C. § 262), or Article 10(4) of the Directive 2001/83/EC, or any other similar regulation promulgated by the FDA, EMA, MHLW, or by other applicable similar Governmental Authority or other actual or potential infringement or Patent challenge by a generic or biosimilar or potential generic or biosimilar competitor (including any Biosimilar Product) to a Licensed Product anywhere in the Territory (collectively, “Competing Infringement”).

10.4.2    As between the Parties, Gilead will have the first right, but not the obligation, to bring and control any legal action or take such other actions as it deems appropriate (including responding to Third Party notice letters and controlling settlements), which may include the granting of licenses and authorizing the launch of Biosimilar Product(s) in connection with any Competing Infringement of any Jounce-Owned Patent as it reasonably determines appropriate, at its cost and expense. If Gilead does not (a) take any such action or (b) notify

Jounce in writing of its intent to allow the applicable Competing Infringement without intervention within a period of [***] days after delivering or receiving, as applicable, notice of such Competing Infringement in accordance with Section 10.4.1, then Jounce will have the right, but not the obligation, to bring and control any such legal action or other actions; provided that: (x) if Applicable Law prevents such actions within such period, then such period will be extended to the date that is [***] days after Applicable Law does not prevent such action; and (y) if a delay in bringing such action would limit or compromise the remedies available for such Competing Infringement, then such [***] day period will be shortened to permit Jounce at least [***] days to initiate such action. At the request and expense of the enforcing Party, the non-enforcing Party will provide reasonable assistance in connection with the enforcing Party’s legal or other actions in connection with any such Competing Infringement, including by executing reasonably appropriate documents, cooperating in discovery, and joining as a party to the action if required.

10.5    Defense. Each Party will promptly notify the other Party of any claim alleging that the Development, Manufacture, or Commercialization of any Licensed Product in the Territory infringes, misappropriates, or otherwise violates any Patents, Know-How, or other intellectual property rights of any Third Party (“Third Party Infringement”). In any such instance, the Parties will as soon as practicable thereafter discuss in good faith the best response to such notice of Third Party Infringement. Subject to Section 10.1, as between the Parties, Gilead will have the sole and exclusive right, but not the obligation, to defend, and take other actions (including to settle) with respect to, any such claim of Third Party Infringement, at Gilead’s sole discretion, cost, and expense.

10.7    Trademarks. Subject to Section 10.1, as between the Parties, Gilead will have the exclusive right, but not the obligation, to brand the Licensed Products using trademarks and trade names it determines appropriate in its sole discretion for the Licensed Products, which may vary within the Territory (the “Licensed Product Marks”). Gilead will own all rights in the Licensed Product Marks and will register and maintain the Licensed Product Marks to the extent it determines reasonably necessary.

10.8    Patent Extensions. As between the Parties, Gilead will have the sole right to obtain patent term restoration (including under the Drug Price Competition and Patent Term Restoration Act), supplemental protection certificates or their equivalents, and patent term extensions (collectively, “Patent Extensions”) with respect to the Jounce-Owned Patents or Joint Patents, where applicable, at Gilead’s sole discretion, cost, and expense. Jounce will provide all reasonable assistance requested by Gilead, including permitting Gilead to proceed with applications for such Patent Extensions in the name of Jounce, if deemed appropriate by Gilead, and executing documents and providing any relevant information and assistance to Gilead.

10.9    Purple Book Listings.

Jounce and

Gilead, as each deems advisable and necessary, may reasonably designate any competitively sensitive material to be provided to the other under this Section 11.2 as “Antitrust Outside Counsel Only Material.” Such materials and the information contained therein will 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 Party unless express permission is obtained in advance from the source of the materials or the applicable Party’s legal counsel.

as soon as reasonably practicable after receiving notice of the claim (an “Indemnification Claim Notice”); provided, that any delay or failure to provide such notice will not constitute a waiver or release of, or otherwise limit, the Indemnitee’s rights to indemnification under Section 14.1 or Section 14.2, as applicable, except to the extent that such delay or failure materially prejudices the Indemnitor’s ability to defend against the relevant claims.

14.3.2    The Indemnitor will have the right and obligation within [***] days after receipt of the Indemnification Claim Notice, to assume the defense of any such claim for which the Indemnitee is seeking indemnification pursuant to Section 14.1 or Section 14.2, as applicable. The Indemnitee will cooperate with the Indemnitor and the Indemnitor’s insurer as the Indemnitor may reasonably request, and at the Indemnitor’s cost and expense. The Indemnitee will have the right to participate, at its own expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the Indemnitor.

14.3.3    The Indemnitor will not settle any claim to which it is subject pursuant to Section 14.1 or Section 14.2 above, as applicable, without first obtaining the prior written consent of the Indemnitee, not to be unreasonably withheld, conditioned, or delayed; provided, however, that the Indemnitor will not be required to obtain such consent if the settlement: (a) involves only the payment of money and will not result in the Indemnitee (or other Jounce Indemnitees or Gilead Indemnitees, as applicable) becoming subject to injunctive or other similar type of relief; (b) does not require an admission by the Indemnitee (or other Jounce Indemnitees or Gilead Indemnitees, as applicable); and (c) does not adversely affect the rights or licenses granted to the Indemnitee (or its Affiliate) under this Agreement. The Indemnitee will not settle or compromise any such claim without first obtaining the prior written consent of the Indemnitor.

14.3.4    If the Parties cannot agree as to the application of Section 14.1 or Section 14.2, as applicable, to any claim, pending the resolution of the dispute pursuant to Section 16.8, the Parties may conduct separate defenses of such claims, with each Party retaining the right to claim indemnification from the other Party in accordance with Section 14.1 or Section 14.2, as applicable, upon resolution of the underlying claim. In each case, the Indemnitee will reasonably cooperate with the Indemnitor and will make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information will be subject to Article 12.

14.4    Insurance. During the Term and for a period of [***] years thereafter, each Party will maintain, at its cost, a program of insurance (or self-insurance, in the case of Gilead) against liability and other risks associated with its activities and obligations under this Agreement (including with respect to its Clinical Trials), 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 including:

The Jounce policy(ies) shall name Gilead, its officers, directors, employees and volunteers, as Additional Insured. [***]. Such insurance will not be construed to create a limit on either Party’s liability with respect to its indemnification obligations under this Article 14, or otherwise.

14.5    LIMITATION OF LIABILITY. NEITHER JOUNCE NOR GILEAD, NOR ANY OF THEIR RESPECTIVE AFFILIATES, WILL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES UNDER OR IN CONNECTION WITH THIS AGREEMENT FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE, OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS OR LOST REVENUES), WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY, CONTRIBUTION, OR OTHERWISE, 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.
