9.7 No Projections. Each of Hookipa and Gilead hereby acknowledges and agrees that nothing in this Agreement shall be construed as representing an estimate or projection of anticipated sales of any Licensed Product, and that the Milestones and Net Sales levels set forth above or elsewhere in this Agreement or that have otherwise been discussed by the Parties are merely intended to define the Milestone Payments and royalty obligations to Hookipa in the event such Milestones or Net Sales levels are achieved, NEITHER HOOKIPA NOR GILEAD MAKES ANY REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, THAT IT WILL BE ABLE TO SUCCESSFULLY DEVELOP, OBTAIN REGULATORY APPROVAL FOR, OR COMMERCIALIZE ANY LICENSED PRODUCT OR, IF COMMERCIALIZED, THAT ANY PARTICULAR NET SALES LEVEL OF SUCH LICENSED PRODUCT WILL BE ACHIEVED.

9.8 Non-Refundable and Non-Creditable Payments. Notwithstanding the non-refundable or non-creditable nature of any payments hereunder, but subject to the limitations set forth in Section 16.5

nothing in this Agreement shall limit either Party’s rights to assert or obtain damages for breach of this Agreement, including damages calculated based on the payments made under this Agreement.

9.9 Allocation of Payment Values.

(a) The Parties agree and acknowledge that: (i) the Licensed Technology comprises Patent Rights, Know-How, and other intellectual property rights both owned by Hookipa and in-licensed by Hookipa from Third Parties under the Hookipa Third Party Agreements set forth in Schedule 9.5(a), as in effect on the Effective Date; and (ii) Hookipa has certain payment obligations to Third Parties under such Hookipa Third Party Agreements based on amounts payable by Gilead to Hookipa under this Agreement in consideration for Hookipa’s grant of a respective sublicense to Gilead in accordance with Section 3.1(a).

(b) To enable Hookipa to correctly calculate the payments due to its Third Party licensors under the Hookipa Third Party Agreements and solely for this purpose, and in acknowledgement that the payments set forth in Sections 9.1, 9.2(c), 9.2(d), and 9.3 are paid in consideration of a license or, as applicable, sublicense to Gilead under the Licensed Technology in its entirety, the Parties agree that the payments set forth in Sections 9.1, 9.2(c), 9.2(d), and 9.3 shall be allocated to the various components of Licensed Technology as follows: (i) [***].

(c) Notwithstanding Sections 9.9(a) and 9.9(b), the Parties agree and acknowledge that one (1) or more of the intellectual property rights comprised by the Licensed Technology may become irrelevant for a given Licensed Product in course of the Research, Development, Manufacture, or Commercialization undertaken under this Agreement. The Parties shall discuss from time to time at the JSC whether any Patent Rights, Know-How, or other intellectual property rights comprised by the Licensed Technology are no longer relevant for further Research, Development, Manufacture, or Commercialization of a Licensed Product, including whether an adjusted allocation of the payments set forth in Sections 9.1, 9.2(c), 9.2(d), and 9.3 to the various components of Licensed Technology is advisable. Upon the Parties’ mutual agreement, if any, on such adjusted allocation, Hookipa will calculate the participation payments due to its Third Party licensors in accordance with such adjusted allocation.

(d) For the avoidance of doubt, the Parties further confirm that the payments set forth in Sections 9.2(a), 9.2(b), and 9.6 are paid as reimbursement of costs and expenses as well as in consideration of the Research work performed and results achieved by Hookipa, and not in consideration of a (sub)license grant.

(b) Each Party (the “Auditing Party”) shall have the right, once per [***] and at its own expense, to have an internationally recognized, independent, certified public accounting firm (the “Auditor”), selected by the Auditing Party and reasonably acceptable to the other Party (the “Audited Party”), review any such records of such other Party (either directly by the Auditing Party or through the Audited Party) in the location(s) where such records are maintained by the Audited Party upon reasonable written notice (which shall be no less than [***] days’ prior written notice) and during regular business hours and under obligations of strict confidence secured through a confidentiality agreement between the Auditor and the Audited Party, for the sole purpose of verifying the basis and accuracy of payments made and deductions taken within the [***] period preceding the date of the request for review. Records for any particular period may be audited only once.

(c) In the event such audit leads to the discovery of a discrepancy to the Auditing Party’s detriment, the Audited Party shall, within [***] days after receipt of such report from the Auditor, pay any undisputed amount of the discrepancy. The Auditing Party shall pay the full cost of the audit unless the underpayment of amounts due or overpayment of amounts payable by the Auditing Party is greater than [***] of the amount due for the entire period being examined, in which case the Audited Party shall pay the reasonable cost charged by the Auditor for such review.

The Recipient Party may only use Confidential Information of the Disclosing Party for the purposes of this Agreement and pursuant to the rights granted to the Recipient Party under this Agreement. Subject to the other provisions of this Article 12, the Recipient Party shall hold as confidential such Confidential Information of the Disclosing Party in the same manner and with the same protection as such Recipient Party maintains its own Confidential Information, but in any event with no less than reasonable protections.

16. INDEMNIFICATION; LIABILITY

16.1 Indemnification by Hookipa. Hookipa shall indemnify and hold Gilead, its Affiliates, and their respective officers, directors, and employees (the “Gilead Indemnitees”) harmless from and against any and all liability, damage, loss, cost, or expense of any nature (including reasonable attorney’s fees and litigation expenses) (“Losses”) incurred by or imposed upon the Gilead Indemnitees or any of them in connection with any claim, suit, action, demand, proceeding, cause of action, or judgment resulting from a Third Party claim (“Claims”), in each case, to the extent arising or resulting from:

(a) Hookipa’s, or any of its Affiliates’ or contractors’ activities in connection with: (i) the Programs; (ii) the Manufacture of Licensed Products; or (iii) other activities under this Agreement;

(b) the negligence or willful misconduct of Hookipa or any of its Affiliates or contractors; or

(c) the breach of any of the obligations, covenants, representations, or warranties made by Hookipa to Gilead under this Agreement;

provided, however, that Hookipa shall not be obliged to so indemnify and hold harmless the Gilead Indemnitees for any Claims to the extent Gilead has an obligation to indemnify Hookipa Indemnitees pursuant to Section 16.2 or to the extent that such Claims arise from the breach, negligence, or willful misconduct of Gilead or any Gilead Indemnitee.

16.2 Indemnification by Gilead. Gilead shall indemnify and hold Hookipa, its Affiliates, and their respective officers, directors, and employees (the “Hookipa Indemnitees”) harmless from and against any and all Losses incurred by or imposed upon the Hookipa Indemnitees or any of them in connection with any Claims, in each case, to the extent arising or resulting from:

(a) Gilead’s, or any of its Affiliates’, sublicensees’, or contractors’ activities in connection with the: (i) Programs; (ii) Development, Manufacture, or Commercialization of the Licensed Products in the Field in the Territory; or (iii) other activities under this Agreement;

(b) the negligence or willful misconduct of Gilead or any of its Affiliates or sublicensees or contractors; or

(c) the breach of any of the obligations, covenants, representations, or warranties made by Gilead to Hookipa under this Agreement;

provided, however, that Gilead shall not be obliged to so indemnify and hold harmless the Hookipa Indemnitees for any Claims to the extent Hookipa has an obligation to indemnify Gilead Indemnitees pursuant to Section 16.1 or to the extent that such Claims arise from the breach, negligence, or willful misconduct of Hookipa or any Hookipa Indemnitee.

16.3 Indemnification Procedure.

(a) For the avoidance of doubt, all indemnification claims in respect of a Gilead Indemnitee or a Hookipa Indemnitee shall be made solely by Gilead or Hookipa, respectively.

(b) A Party seeking indemnification hereunder (the “Indemnified Party”) shall notify the other Party (the “Indemnifying Party”) in writing reasonably promptly after the assertion against the Indemnified Party of any Claim or fact in respect of which the Indemnified Party intends to base a claim for indemnification hereunder (each, an “Indemnification Claim Notice”); provided, that

the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation or liability that it may have to the Indemnified Party, except to the extent that the Indemnifying Party demonstrates that its ability to defend or resolve such Claim is adversely affected thereby. The Indemnification Claim Notice shall contain a description of the Claim and the nature and amount of the Claim (to the extent that the nature and amount of such Claim is known at such time). Upon the request of the Indemnifying Party, the Indemnified Party shall furnish promptly to the Indemnifying Party copies of all correspondence, communications and official documents (including court documents) received or sent in respect of such Claim.

(c) Subject to Sections 16.3(d) and 16.3(e), the Indemnifying Party shall have the right, upon written notice given to the Indemnified Party within [***] days after receipt of the Indemnification Claim Notice, to assume the defense and handling of such Claim, at the Indemnifying Party’s sole expense, in which case the provisions of Section 16.3(d) below shall govern; provided, that any such Claim is only for monetary damages. The assumption of the defense of a Claim by the Indemnifying Party shall not be construed as acknowledgement that the Indemnifying Party is liable to indemnify any Indemnitee in respect of the Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against any Indemnified Party’s claim for indemnification. In the event that it is ultimately decided that the Indemnifying Party is not obligated to indemnify or hold an Indemnitee harmless from and against the Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all reasonable costs and expenses (including reasonable attorneys’ fees and costs of suit) and any losses incurred by the Indemnifying Party in its defense of the Claim. If the Indemnifying Party does not give written notice to the Indemnified Party, within [***] days after receipt of the Indemnification Claim Notice, of the Indemnifying Party’s election to assume the defense and handling of such Claim, the provisions of Section 16.3(e) shall govern.

(d) Upon assumption of the defense of a Claim by the Indemnifying Party: (i) the Indemnifying Party shall have the right to and shall assume sole control and responsibility for dealing with the Claim; (ii) the Indemnifying Party may, at its own cost, appoint as counsel in connection with conducting the defense and handling of such Claim any law firm or counsel reasonably selected by the Indemnifying Party; (iii) the Indemnifying Party shall keep the Indemnified Party informed of the status of such Claim; and (iv) the Indemnifying Party shall have the right to settle the Claim on any terms the Indemnifying Party chooses; provided, however, that it shall not, without the prior written consent of the Indemnified Party (such consent not to be unreasonably withheld, conditioned, or delayed), agree to a settlement of any Claim which could lead to liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder or which admits any wrongdoing or responsibility for the claim on behalf of the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party and shall be entitled to participate in, but not control, the defense of such Claim with its own counsel and at its own expense. In particular, the Indemnified Party shall furnish such records, information, and testimony, provide witnesses, and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours by the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Claim, and making the Indemnified Party, the Indemnitees and its and their employees and agents available on a mutually convenient basis to provide additional information and explanation of any records or information provided.

(e) If the Indemnifying Party does not give written notice to the Indemnified Party as set forth in Section 16.3(c) or fails to conduct the defense and handling of any Claim in good faith after having assumed such, the Indemnified Party may, at the Indemnifying Party’s expense, select counsel reasonably acceptable to the Indemnifying Party in connection with conducting the defense and handling of such Claim and defend or handle such Claim in such manner as it may deem appropriate. In such

event, the Indemnified Party shall keep the Indemnifying Party timely apprised of the status of such Claim and shall not settle such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned, or delayed. If the Indemnified Party defends or handles such Claim, the Indemnifying Party shall cooperate with the Indemnified Party, at the Indemnified Party’s request but at no expense to the Indemnified Party, and shall be entitled to participate in the defense and handling of such Claim with its own counsel and at its own expense.

16.4 Mitigation of Loss. Each Indemnified Party shall take and shall procure that its Affiliates take all such reasonable steps and action as are necessary or as the Indemnifying Party may reasonably require in order to mitigate any Claims (or potential losses or damages) under this Article 16. Nothing in this Agreement shall or shall be deemed to relieve any Party of any common law or other duty to mitigate any losses incurred by it.

16.5 Special, Indirect and Other Losses. NEITHER PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE IN CONTRACT, TORT, NEGLIGENCE, BREACH OF STATUTORY DUTY, OR OTHERWISE FOR ANY SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES OR FOR ANY LOSS OF PROFITS SUFFERED BY THE OTHER PARTY, EXCEPT TO THE EXTENT ANY SUCH DAMAGES ARE: [***].

16.6 No Exclusion. Neither Party excludes any liability for death or personal injury caused by its negligence or willful misconduct or that of its officers, directors, employees, agents, sublicensees, or sub-contractors.

16.7 Insurance. Each Party shall maintain, at its cost, insurance against liability and other risks associated with its activities and obligations under this Agreement, in such amounts and on such terms as are customary for a company such as the respective Party for the activities to be conducted by it under this Agreement. Each Party shall furnish to the other Party evidence of such insurance upon request. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 16.

17. PUBLICATIONS AND PUBLICITY

17.1 Publications.

(a) Except to the extent made in accordance with the provisions of Article 12 or Section 17.2, any proposed public disclosure (whether written, electronic, oral, or otherwise) by Hookipa or any of its Affiliates relating to the Licensed Products shall require, in each case, the prior written consent of Gilead (such consent not to be unreasonably withheld, conditioned, or delayed).

(b) For the avoidance of doubt, Gilead or any of its Affiliates shall have the sole right, without any required consents from Hookipa, but, to the extent practicable, with at least [***] days’ prior written notice to Hookipa, to publish or have published information about clinical trials related to the Licensed Products, including the results of such clinical trials, or other activities under this Agreement. This Section 17.1(b) shall not affect the rights or obligations of the Parties pursuant to Article 12.

17.2 Publicity.

(a) Use of Name. Unless otherwise provided in this Agreement, neither Party shall use the name, symbol, trademark, trade name, or logo of the other Party or its Affiliates in any press release, publication, or other form of public disclosure without, in each case, first obtaining the prior

written consent of the other Party (such consent not to be unreasonably withheld, conditioned, or delayed).

(b) Press Releases. On or promptly after the Effective Date, the Parties shall issue a public announcement of the execution of this Agreement in the form attached hereto as Schedule 17.2(b). Except as provided in this Section 17.2(b) or in Article 12 each Party agrees not to issue any press release or other public statement, whether written, electronic, oral, or otherwise, disclosing the existence of this Agreement, the terms of this Agreement, or any information relating to this Agreement without, in each case, first obtaining the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned, or delayed; provided, however, that: (i) Gilead may issue press releases and other public statements as it deems reasonably appropriate in connection with the Research, Development, Manufacture, or Commercialization of Licensed Products under this Agreement without such consent, but, to the extent practicable, with at least [***] Business Days’ prior written notice to Hookipa; (ii) Hookipa and any of its Affiliates may issue press releases and other public statements as it deems reasonably appropriate to communicate the receipt of Regulatory Approval for any Licensed Product or the receipt of any Milestone Payment or royalty payments from Gilead pursuant to Section 9.2 or Section 9.3, including the corresponding triggering event, without such consent, but, to the extent practicable, with at least [***] Business Days’ prior written notice to Gilead; provided, that such press release or statement by Hookipa or its Affiliates shall not disclose the amount of such Milestone Payment or royalty payment; and (iii) without limiting the foregoing clauses (i) and (ii), the Parties shall discuss in good faith from time to time the advisability of joint or individual press releases with respect to any material progress of a Program or the Research, Development, Manufacture, or Commercialization of Licensed Products under this Agreement; provided, that the issuance and substance of any such press release contemplated by this clause (iii) shall be subject to mutual agreement of the Parties.

(c) Re-Publication. Nothing in Article 12 or this Article 17 (but subject to the Parties’ other obligations under this Agreement) shall prohibit either Party or its Affiliates from including, in future publications or press releases, any information that was previously publicly disclosed by the other Party or its Affiliates (other than by breach of this Agreement). Any authorization by a Party for information to be publicly disclosed in any publication or press release of the other Party or its Affiliates shall be valid for [***] days.

18. GENERAL PROVISIONS

18.1 Assignment. This Agreement may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party; provided, however, that either Party may assign this Agreement or individual rights or obligations thereunder without the consent of the other Party: (a) to any of its Affiliates; or (b) to a successor to all or substantially all of its business or assets to which this Agreement relates. Any purported assignment in contravention of this Section 18.1 shall be null and void and of no effect. No assignment shall release either Party from responsibility for the performance of its accrued obligations under this Agreement and upon any such assignment, the assigning Party shall remain liable for the performance of this Agreement and for any acts or omissions of its assignee or its successor constituting a breach of this Agreement. This Agreement shall be binding upon and enforceable against the successor to or any permitted assignees from either of the Parties.

18.2 Extension to Affiliates. Gilead shall have the right to extend the rights, immunities, and obligations granted in this Agreement to one (1) or more of its Affiliates. All applicable terms and provisions of this Agreement shall apply to any such Affiliate to which this Agreement has been extended to the same extent as such terms and provisions apply to Gilead. Gilead shall remain primarily liable for any acts or omissions of its Affiliates.

18.3 Severability. To the extent permitted under any Applicable Laws, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under Applicable Laws, but should one (1) or more of the provisions of this Agreement become void or unenforceable as a matter of law, then such provision(s) shall be void and unenforceable only to the extent of such invalidity or unenforceability, without invaliding the remainder of this Agreement. In such case, this Agreement shall be construed as if such provision(s) were not contained herein and the remainder of this Agreement shall be in full force and effect, and the Parties shall use their commercially reasonable efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision which conforms as nearly as possible with the original intent of the Parties.

18.4 Governing Law and Waiver of Jury Trial.

(a) This Agreement and any dispute arising from the performance or breach hereof shall be governed by and interpreted in accordance with the laws of the State of New York, without giving effect to the application of any conflict of laws principles that would require application of the laws of another jurisdiction. The provisions of the United Nations Convention on Contracts for the International Sale of Goods shall not apply to this Agreement or any subject matter hereof.

(b) THE PARTIES HEREBY WAIVE, AND COVENANT THAT THEY SHALL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT, OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY, AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE ITS RIGHT TO TRIAL BY JURY IN ANY PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS AGREEMENT SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

18.5 Dispute Resolution; Rules of Arbitration.

(a) Initial Dispute Resolution Process. Except as otherwise set forth in this Agreement, in the event of an unresolved matter, dispute, or issue which relates to the breach or alleged breach or interpretation of this Agreement (each, a “Dispute”) or which this Agreement expressly provides shall be resolved in accordance with this Section 18.5 (each, a “Selected Dispute”), the Parties shall refer the Dispute or Selected Dispute to the Alliance Managers for discussion and resolution. If the Alliance Managers are unable to resolve such Dispute or Selected Dispute within [***] days of the Dispute or Selected Dispute being referred to them by either Party in writing, either Party may require that the Parties forward the matter to the Senior Officers (or designees with similar authority to resolve such dispute), who shall attempt in good faith to resolve such Dispute or Selected Dispute. If the Senior Officers cannot resolve such Dispute or Selected Dispute within [***] days of the matter being referred to them in writing, then the Dispute or Selected Dispute shall be resolved as provided in Sections 18.5(b), 18.5(c), or 18.5(e) as applicable.

(b) Arbitration. Any unresolved Dispute or Selected Dispute between the Parties arising out of or in connection with this Agreement shall be resolved by final and binding arbitration. Whenever a Party decides to institute arbitration proceedings, it shall give written notice to that effect to the other Party. Arbitration shall be held in New York, New York, according to the Rules of Arbitration of the International Chamber of Commerce (“ICC Rules”) in effect at the Effective Date, except as they may be modified herein or by mutual agreement of the Parties. All arbitration proceedings shall be

conducted by three (3) arbitrators unless otherwise mutually agreed by the Parties. The claimant and the respondent shall each nominate an arbitrator in accordance with the ICC Rules, and the third arbitrator, who shall be the president of the arbitral tribunal, shall be appointed by the two (2) Party-appointed arbitrators in consultation with the Parties. The arbitrators shall: (i) be disinterested, neutral, and independent from both Parties and all of their respective Affiliates; and (ii) have the requisite experience and expertise in licensing and partnering agreements in the pharmaceutical and biotechnology industries, shall have appropriate experience with respect to the subject matter(s) to be arbitrated, and shall have some experience in mediating or arbitrating issues relating to such agreements. In the case of any Dispute involving an alleged failure to use Commercially Reasonable Efforts, the arbitrators shall in addition be an individual with experience and expertise in the worldwide development and commercialization of pharmaceuticals and the business, legal and scientific considerations related thereto. The Arbitrators shall have the authority to engage additional experts as necessary in order to facilitate resolution of the Dispute or Selected Dispute, as applicable.

(c) Selected Dispute Arbitration. Within [***] days after the arbitrators for a Selected Dispute are nominated or appointed pursuant to Section 18.5(b), each Party shall provide the arbitrators a proposal and written memorandum in support of its position regarding the Selected Dispute, including its specific proposal to resolve the Selected Dispute, as well as any documentary evidence it wishes to provide in support thereof (each, a “Brief”), and the arbitrators shall provide each Party’s Brief to the other Party after it receives a Brief from each Party. Within [***] days after a Party submits its Brief, the other Party shall have the right to respond thereto. The response and any material in support thereof (each, a “Response”) will be provided to the arbitrators and the other Party. The arbitrators shall have the right to meet with the Parties as necessary to inform the arbitrators’ determination and to perform independent research and analysis. Within [***] days of the receipt by the arbitrators of both Parties’ Responses (or expiration of the [***]-day period if any Party fails to submit a Response), the arbitrators shall deliver their decision regarding the Selected Dispute in writing; provided, that the arbitrators shall select one (1) of the resolutions proposed by the Parties which corresponds with, or comes closer to, the determination of the arbitrators.

(d) Confidentiality; Awards. The Parties undertake to maintain confidentiality in accordance with Article 12 as to the existence of the arbitration proceedings and as to all submissions, correspondence, evidence, and findings relating to the arbitration proceedings. Sections 18.5(b) and 18.5(c) shall survive the termination of the arbitral proceedings. No arbitrator (nor any arbitral tribunal) shall have the power to award punitive damages under this Agreement, and such award is expressly prohibited. Decisions of the arbitrator(s) shall be final and binding on the Parties, Judgment on the award so rendered may be entered in any court of competent jurisdiction. The costs of the arbitration shall be shared by the Parties during the course of such arbitration, as assessed by the International Chamber of Commerce, and shall be borne as determined by the arbitrator(s).

(e) Preliminary Injunctive Relief. Notwithstanding anything to the contrary, either Party may at any time seek to obtain preliminary injunctive relief or other applicable provisional relief from a court of competent jurisdiction with respect to an issue arising under this Agreement if the rights of such Party would be prejudiced absent such relief. A request by a Party to a court of competent jurisdiction for interim measures necessary to preserve the Party’s rights, including attachments or injunctions, shall not be deemed incompatible with, or a waiver of, the agreement to mediate or arbitrate contained in this Section 18.5, or the availability of interim measures of protection under the ICC Rules. Notwithstanding anything to the contrary in this Section 18.5, any disputes regarding the scope, validity, enforceability, or inventorship of any Patent Rights shall be submitted for final resolution by a court of competent jurisdiction.

18.6 Force Majeure. Neither Party shall be responsible to the other for any failure or delay in performing any of its obligations under this Agreement or for other nonperformance hereunder if such delay or nonperformance is caused by strike, stoppage of labor, lockout or other labor trouble, earthquake, fire, flood, accident, war, act of terrorism, act of God or of the government of any country or of any local government, or by any other cause unavoidable or beyond the control of any Party. In such event, the Party affected shall provide the other Party with written notice of the full particulars of the force majeure event as soon as it becomes aware thereof, including its best estimate of the likely extent and duration of the interference with its activities, and shall use Commercially Reasonable Efforts to resume performance of its obligations as soon as practicable.

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

18.8 Relationship of the Parties. Nothing contained in this Agreement shall be deemed to constitute a partnership, joint venture, agency, employee-employer relationship, or legal entity of any type between Hookipa and Gilead, or to constitute one as the agent of the other. Each Party agrees not to construe this Agreement, or any of the transactions contemplated hereby, as a partnership for any tax purposes. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give any Party the power or authority to act for, bind, or commit the other.

18.9 Notices. All notices and other communications between the Parties shall be in writing and shall be deemed to have been duly given: (a) when delivered in person; or (b) when delivered by FedEx or other internationally recognized overnight delivery service, addressed as follows:

18.12 No Third Party Beneficiary Rights. The provisions of this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they shall not be construed as conferring any rights to any Third Party (including any third party beneficiary rights), except for the indemnification rights of the Gilead Indemnitees pursuant to Sections 16.1 and 16.3 and the indemnification rights of the Hookipa Indemnitees pursuant to Sections 16.2 and 16.3.

In the event of any conflict between a substantive provision of this Agreement and any Exhibit or Schedule hereto, the substantive provisions of this Agreement shall prevail.

18.16 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one (1) and the same instrument.

Hookipa and Gilead Enter into a Collaboration and License Agreement to Develop Immunotherapies Against HIV and Hepatitis B

· Hookipa and Gilead will jointly develop therapeutics against HIV and Hepatitis B infections

· Hookipa and Gilead will jointly research and Hookipa xxxx manufacture arenavirus-based vectors for clinical development by Gilead

· The deal expands the relationship between Hookipa and Gilead following Gilead’s participation in Hookipa’s Series C financing in December 2017

· Total potential deal value exceeds $400 million, including upfront and milestone payments, plus research and development funding

Vienna, Austria and Foster City, CA, 5 June 2018 - Hookipa Biotech AG (“Hookipa”), a clinical-stage biotech company pioneering an innovative class of active immunization therapies for oncology and infectious diseases and Gilead Sciences, Inc., (“Gilead”), a research-based biopharmaceutical company that discovers, develops and commercializes innovative medicines in areas of unmet medical need, today announced that they have entered into a research collaboration and license agreement that grants Gilead exclusive rights to Hookipa’s TheraT® and Vaxwave® arenavirus vector-based immunization technologies for two major chronic infectious disease indications, hepatitis B virus (HBV) and human immunodeficiency virus (HIV).

Under the terms of the agreement, Gilead will provide an upfront payment of $10 million. Additionally, Hookipa will be eligible to receive milestone payments based upon the achievement of specified development, regulatory, and commercial milestones up to a total of more than $400 million. Gilead will fund all research and development activities. Hookipa will also be eligible to receive tiered royalties on net sales.

“Gilead, a world leader in innovative therapies against major viral diseases, is the ideal partner for us to drive our pipeline development in this area for the benefit of patients in need. This partnership is strong recognition of our unique immunization technology, and helps us concentrate our own energy and resources on immuno-oncology,” commented Xxxxx Xxxxx, Chief Executive Officer of Hookipa. “The collaborative HIV and HBV programs nicely complement our significant efforts in the infectious disease area with an exciting proprietary prophylactic CMV vaccine.”

“Gilead is committed to advancing innovative approaches directed at functional cures against HIV and HBV,” said Xxxx Xxx, PhD, Executive Vice President of Research, Gilead. “We are convinced that Hookipa’s unique therapeutic vaccine technology, which has demonstrated excellent safety and immunogenicity in Phase 1 clinical studies, has strong potential to have synergistic effect with other Gilead cure efforts in both of these diseases areas. Our ultimate long-term goal is to eliminate the need for life-long antiviral therapy for millions of patients around the world.”

About Hookipa Biotech

Hookipa Biotech is a clinical stage company developing next-generation immunotherapies for infectious diseases and cancer using novel proprietary arenavirus vector platforms.

Hookipa’s Vaxwave® technology presents a completely new replication-defective viral vector platform designed to overcome the limitations of current technologies. Vaxwave® is based on lymphocytic choriomeningitis virus (LCMV). In this vector the gene encoding the LCMV envelope protein, normally responsible for virus entry into target cells, has been deleted and replaced with an antigen of interest. The resulting vectors infect dendritic cells and stimulate very potent and long-lasting immune response, however they cannot replicate and are therefore non-pathogenic and inherently safe.

Hookipa’s TheraT® platform is based on an attenuated replicating arenavirus and is capable of eliciting the most potent T cell responses - a crucial step in treating patients with aggressive cancers. Significant pre-clinical data demonstrates that TheraT is a powerful modality capable of turning “cold tumors hot” which should result in an additional layer of efficacy in the fight against solid tumors. Specifically, TheraT® has proven to be safe in animals as well as capable of eliciting uniquely potent antigen-specific CD8+ cytotoxic T cell responses and strong tumor control in mice. The first clinical trial with HB-201 targeting human papilloma virus-induced head and neck cancer is currently being prepared. This immuno-oncology technology is further being leveraged to target tumor self-antigens or shared neoantigens.
