The Parties will endeavor to make decisions of the JPC by consensus; provided that GSK will have the tie-breaking vote in the event of any dispute; provided, further, that no decision by GSK may be in conflict with any of the terms of this Agreement (including by amending or increasing any obligations on Surface or any of its Affiliates or by granting any licenses or other rights to GSK or any of its Affiliates that, in each case, are not expressly set forth in this Agreement).

(c) Disbanding of JPC. Unless otherwise agreed by the Parties, the JPC will have no further responsibilities and will disband at the end of the Term.

(d) Limitations on Authority of the JPC. Except as otherwise provided in this Agreement, the JPC will have solely the roles and responsibilities assigned to it in this ARTICLE VI. The JPC will have no authority to amend, modify or waive compliance with this Agreement or make any decision other that those specifically assigned under this Agreement to be made by the JPC.

Each Alliance Manager shall attend meetings of the JDC as a non-voting observer. The Alliance Managers shall be the primary point of contact for the Parties regarding communications contemplated by this Agreement, whether formal reporting obligations or otherwise, including after disbanding of the JDC. The Alliance Managers shall also be responsible for assisting the JDC in performing its responsibilities such as scheduling meetings, circulating agendas as necessary and preparing and finalizing the minutes from meetings of the JDC. Each Party may replace its Alliance Manager, in its sole discretion, from time to time, upon notification to the other Party, which notice may be given by e-mail, sent to the other Party.

FINANCIAL PROVISIONS

Section 7.1. Upfront Payment; Milestone Payments.

(a) Upfront Payment. Subject to the terms and conditions of this Agreement, and in partial consideration for the rights granted to GSK under this Agreement, GSK will pay Surface a non-refundable, non-creditable payment in the amount of Eighty-Five Million U.S. Dollars (US$ 85,000,000), which upfront payment will be due and payable to Surface within [***] Business Days following receipt of an invoice from Surface for such payment on or after the Effective Date.

(b) Development Milestone Payment. During the Term, GSK will notify Surface in writing of the achievement by or on behalf of GSK, its Affiliates or its or their Sublicensees of any milestone event set forth in this Section 7.1(b) (each, a “Development Milestone Event”) within [***] after the occurrence thereof. After receipt of such notice, Surface will submit an invoice to GSK for the corresponding non-refundable, non-creditable milestone payment set forth in the tables below (each, a “Development Milestone Payment”). GSK will make the corresponding Development Milestone Payment by [***] from GSK’s receipt of an invoice, in accordance with GSK’s standard payment terms. Each of the Development Milestone Payments set forth in this Section 7.1(b) is payable only one time upon the first achievement of the corresponding Development Milestone Event by the first Licensed Product to achieve such Development Milestone Event and no amounts shall be due for subsequent or repeated achievements of such Development Milestone Event, whether for the same or a different Licensed Product.

24

Notwithstanding anything to the contrary set forth herein, [***]. The maximum aggregate amount of Development Milestone Payments payable by GSK pursuant to this Section 7.1(b) is Two Hundred Forty-Five Million U.S. Dollars ($245,000,000).

(c) Sales Milestone Payments. During the Term, GSK will notify Surface in writing of the achievement by or on behalf of GSK, its Affiliates or its or their Sublicensees of any milestone event set forth in this Section 7.1(c) (each, a “Sales Milestone Event” and the corresponding payment, a “Sales Milestone Payment”) within [***] after becoming aware of the occurrence thereof. Each of the Sales Milestone Payments set forth in this Section 7.1(c) is payable only upon the first achievement of such Sales Milestone Event and none of the Sales Milestone Payments will be payable more than once and no amounts shall be due for subsequent or repeated achievements of such Sales Milestone Event, whether for the same or a different Licensed Product. For clarity, but subject to the following sentence, the Sales Milestone Payments will be additive such that if all [***] Sales Milestone Events set forth below are achieved in the same Calendar Year, GSK will pay to Surface a payment of Four Hundred Eighty-Five Million Dollars ($485,000,000), and the maximum aggregate amount of Sales Milestone Payments payable by GSK pursuant to this Section 7.1(c) is Four Hundred Eighty-Five Million Dollars ($485,000,000). [***]. After receipt of any notice under this Section 7.1(c) regarding achievement of a Sales Milestone Event [***], Surface will submit an invoice to GSK for the corresponding non-refundable, non-creditable Sales Milestone Payment [***]. GSK will make the corresponding Sales Milestone Payment [***] by [***] from GSK’s receipt of an invoice, in accordance with GSK’s standard payment terms.

25

Section 7.2. Royalties.

(a) Royalty Rate. Subject to the terms and conditions of this Agreement, and in partial consideration for the rights granted to GSK under this Agreement, during the Royalty Term, GSK will pay to Surface non-refundable, non-creditable royalties (except in the case of an overpayment as set forth in Section 7.5(b)) at the graduated royalty rates specified in the following table with respect to the aggregate annual worldwide Net Sales of all Licensed Products across all indications in the Territory in a given Calendar Year:

(b) Royalty Term. Royalties will be due under this Section 7.2 with respect to a given Licensed Product in a given country in the Territory during the period commencing upon the First Commercial Sale of such Licensed Product in such country and ending upon the later of (i) the expiration of the last-to-expire Valid Claim that Covers the composition of matter or approved method of use of such Licensed Product or the Licensed Antibody contained in such Licensed Product in such country, (ii) the expiration of the Regulatory Exclusivity Period with respect to such Licensed Product in such country, or (iii) the tenth (10th) anniversary of the First Commercial Sale of such Licensed Product in such country (such period, the “Royalty Term”). For clarity, once the Royalty Term has expired in a given country in the Territory, Net Sales in such country will not be included in the calculation of the aggregate annual worldwide Net Sales used to determine the royalty rate.

26

Section 7.3. Royalty Payments and Reports. Within [***] after the end of each Calendar Quarter, commencing with the Calendar Quarter during which the First Commercial Sale of a Licensed Product is made anywhere in the Territory, GSK will provide to Surface a report setting forth on a Licensed Product–by–Licensed Product and country-by-country basis (a) the Net Sales; and (b) the calculation of the royalties payable under this Agreement on account of those Net Sales. Each royalty report along with the royalties shown to have accrued on that report are due and payable to Surface within [***] following the end of such Calendar Quarter. All payments due under this Section 7.3 shall be made by bank wire transfer in immediately available funds to an account designated by Surface.

Section 7.4. Royalty Payment Reductions. The royalties payable under Section 7.2 will be subject to the following:

(a) Third Party Licenses. If GSK enters into a license agreement after the Effective Date with a Third Party for the right to use or Commercialize a Licensed Product under intellectual property controlled by such Third Party, pursuant to which GSK pays a royalty to such Third Party for the right to use or Commercialize such Licensed Product under such Patent Rights, then, subject to Section 7.4(e), GSK may deduct [***] of all upfront payment, milestone payments, and royalty payments paid to such Third Party to the extent attributable to the use or Commercialization of such Licensed Product against the royalties due under Section 7.2; provided that GSK shall have the right to carry forward for application against royalties payable to Surface with respect to Net Sales of such Licensed Product in future periods any amount that is not so credited due to the limitation in Section 7.4(e).

(b) [***].

(c) Lack of Patent Protection. Subject to Section 7.4(e) the royalties payable to Surface with respect to Net Sales of Licensed Products shall be reduced, on a Licensed Product–by–Licensed Product and country-by-country basis, to [***] of the amounts otherwise payable pursuant to Section 7.2 during any portion of the Royalty Term upon expiration of the last-to-expire Valid Patent Claim Covering the composition of matter or method of use of the applicable Licensed Product in that country.

(d) Biosimilar Competition. If, on a Licensed Product-by-Licensed Product and country-by-country basis, at least one Biosimilar Product is commercially available with respect to such Licensed Product in such country and the combined market share for all such Biosimilar Products [***]. Unit volume sales will be identified and calculated based on relevant information published by IQVIA, any successor to IQVIA, or any other similar industry-standard Third Party source used by GSK.

(e) Cumulative Deductions. Notwithstanding the foregoing, in no event will the deductions set forth in Section 7.4(a) through Section 7.4(d) reduce the royalties otherwise payable to Surface as specified in Section 7.2(a) by more than [***].

Section 7.5. Financial Audits.

(a) Record Keeping. GSK and its Affiliates will, and will cause their respective Sublicensees to, keep complete, true and accurate books and records in accordance with its Accounting Standards of the items underlying (i) Net Sales, (ii) royalty payments under this Agreement and (iii) [***]. GSK and its Affiliates will, and will cause their respective Sublicensees to keep, such books and records for at least [***] following the Calendar Quarter to which they pertain. Surface [***] will have the right annually, at its own expense, to have an internationally-recognized independent, certified public accountant, selected by Surface [***] and reasonably acceptable to GSK (the “Auditor”), review any such records of GSK in the location(s) where such records are customarily maintained by GSK upon at least [***] prior written notice, during regular business hours and under obligations of confidentiality, except to the extent necessary to enforce Surface’s rights under this Agreement [***] or if disclosure is required by applicable Law, for the sole purpose of verifying the basis and accuracy of payments made under this Agreement and

27

the content of the reports described in Section 7.3, within the prior [***] period after receipt of such report. The Auditor will have the right to disclose to Surface ([***] its conclusions regarding any payment owed under this Agreement. The records for any Calendar Year may be audited no more than once with respect to records covering any specific period of time.

(b) Audit Report. The report prepared by the Auditor, a copy of which will be sent or otherwise provided to each Party by such Auditor at the same time before such report is considered final, will contain the conclusions of such Auditor regarding the audit and will specify that the amounts paid pursuant thereto were correct or, if incorrect, the amount of any underpayment or overpayment, and the specific details regarding any discrepancies. No other information will be provided to Surface without the prior consent of GSK unless disclosure is required by applicable Laws, and if so determined by Surface in consultation with GSK, it will, if permitted, give GSK prior notice thereof to the extent possible for GSK to seek a protective order against or limiting such disclosure. If such report shows any underpayment, then GSK will remit to Surface, within [***] after receipt of such report, (i) the amount of such underpayment and (ii) if such underpayment exceeds [***] of the total amount owed for the period then being audited, the actual costs incurred by Surface in conducting such review. For the avoidance of doubt, payment of the underpayment will be considered a late payment, subject to Section 7.9. If such report shows any overpayment, then at Surface’s election, either GSK will deduct the overpaid amount for application against future payments owed to Surface or Surface will reimburse GSK the amount of such overpayment. The Parties mutually agree that all information subject to review under this Section 7.5 is Confidential Information of both Parties and that the receiving Party will retain and cause the Auditor to retain all such information in confidence in accordance with confidentiality and non-use obligations no less stringent than those contained in ARTICLE IX.

Section 7.6. Tax Withholding. Any tax paid or required to be withheld by GSK under applicable Laws in effect at the time of payment for the benefit of Surface on account of any royalties or other payments payable to Surface under this Agreement shall be deducted from the amount of royalties or other payments otherwise due. The Parties shall reasonably cooperate with one another to reduce or minimize any such deduction or withholding required by applicable Laws, including by providing any forms or other certifications necessary to reduce the amount of such withholding (i.e. including duly completed IRS Form W-9 or applicable IRS Form W-8). If, in accordance with the foregoing, GSK withholds any amount, then it will pay to Surface the balance when due, timely remit to the proper taxing authority the withheld amount, and send Surface proof of such remittance within [***] following Surface’s request for such proof of remittance. Notwithstanding the foregoing, GSK shall assume the responsibility for, and increase the amount payable hereunder such that Surface receives the amount it would have received but for, any Incremental Withholding (as defined below) in the event that such Incremental Withholding arises as a result of any Withholding Action by or on behalf of GSK. For purposes of this Section, “Withholding Action” by or on behalf of GSK means any action taken by GSK that would directly result in any additional withholding or reduction from payments made hereunder (any such amount withheld or deducted, an “Incremental Withholding”, which would not have resulted absent GSK taking, or causing to be taken, such action).

Section 7.7. VAT and Indirect Taxes. All amounts payable under or in connection with this Agreement are exclusive of VAT & Indirect Taxes. Any VAT & Indirect Taxes payable on the consideration shall be paid at the same time as the payment or provision of the consideration to which it relates, subject to the production of a VAT invoice. GSK will provide to Surface within [***] after the earlier of the Effective Date and receipt of any consideration or a valid VAT invoice, if appropriate. If such amounts of VAT & Indirect Taxes are refunded subsequently by the fiscal authorities to GSK, GSK will refund these monies to Surface within [***] of receipt.

28

Section 7.8. Currency of Payments. All amounts payable and calculations under this Agreement will be in Dollars. As applicable, Net Sales and any royalty reductions will be calculated using GSK’s standard conversion method consistent with its applicable Accounting Standards in a manner consistent with GSK’s customary and usual conversion procedures used in preparing its financial statements applied on a consistent basis, provided that such procedures use a widely accepted source of published exchange rates, which as of the Effective Date is Reuters/Bloomberg. All payments under this Agreement will be paid in Dollars by wire transfer to an account designated by the receiving Party (which account the receiving Party may update from time to time in writing).

Section 7.9. Late Payments. Without limiting any other rights or remedies available to Surface hereunder, any undisputed late payment or portion thereof by GSK will bear interest, to the extent permitted by Laws, at an annual rate of [***] above the applicable daily rate published in the Wall Street Journal (or any other qualified source that is acceptable to both Parties) on the date payment was due or the highest rate permitted by law (whichever is lower), computed from the date such payment was due until the date GSK makes the payment. Where the late payment is caused by Surface, including for reasons such as failure to communicate in a timely manner changes to bank details, or failure to respond to communications from GSK regarding the interpretation or dispute of the terms of such payment, then no interest will be payable by GSK.

Section 7.10. Invoices. To the extent an invoice is required to be submitted to GSK under this Agreement, such invoice shall include the information set forth on Schedule 7.10.

Section 7.11. [***].

ARTICLE VIII

INTELLECTUAL PROPERTY OWNERSHIP,

PROTECTION AND RELATED MATTERS

Section 8.1. Ownership.

(a) Subject only to the rights expressly granted to GSK under this Agreement, Surface will retain all rights, title and interests in and to the Licensed Patents and Licensed Know-How.

(b) As between the Parties, each Party will own all inventions and Know-How conceived, discovered, developed or otherwise made, as necessary to establish authorship (in case of publication and other copyrightable work), inventorship (in case of inventions, whether patentable or not) or ownership under applicable Law, solely by or on behalf of such Party (or its Affiliates, its or their subcontractors or sublicensees (including Sublicensees) or its or their respective directors, officers, employees or agents) in the course of conducting such Party’s activities or exercising such Party’s rights under this Agreement, and any and all Patent Rights and other intellectual property rights thereto (collectively, “Sole Inventions” and with respect to GSK, “GSK Sole Inventions” and with respect to Surface, “Surface Sole Inventions”). All Patent Rights claiming patentable GSK Sole Inventions will be referred to herein as “GSK Patents.” All Patent Rights claiming patentable Surface Sole Inventions will be considered Licensed Patents.

(c) As between the Parties, each Party will own an equal, undivided interest in all inventions and Know-How that are conceived, discovered, developed or otherwise made, as necessary to establish authorship (in case of publication and other copyrightable work), inventorship (in case of inventions, whether patentable or not) or ownership under applicable Law, jointly by or on behalf of each Party (or their respective Affiliates, subcontractors or sublicensees (including Sublicensees) or its or their respective directors, officers, employees or agents) in the course of performing activities or exercising rights

29

under this Agreement, whether or not patentable (collectively, “Joint Inventions”), and any and all Joint Patents and other intellectual property rights thereto. Each Party will have full rights to license, assign and exploit such Party’s interest in such Joint Inventions (and any Joint Patents arising therefrom) anywhere in the world, without any requirement of gaining the consent of, or accounting to, the other Party, subject to the licenses granted herein and subject to any other intellectual property held by such other Party. Each Party will promptly disclose to the other via the JPC all Joint Inventions, in each case, including all invention disclosures or other similar documents submitted to such Party by its, or its Affiliates’ subcontractors or sublicensees (including Sublicensees’) or its or their directors, officers, employees or agents, describing such Joint Inventions.

(d) Assignment Obligation. Each Party will assign its rights, and cause all employees of such Party who perform activities for such Party under this Agreement to be under an obligation to assign their rights, in any Patent Rights and Know-How, whether or not patentable, resulting therefrom to such Party to effectuate the terms and conditions set forth in this Section 8.1. With respect to any activities of a Party under this Agreement that are subcontracted to a Person that is not an employee, the Party retaining such subcontractor will include in the applicable subcontract an assignment to such Party of all rights in Patent Rights and Know-How made by such subcontractor resulting from such activities, and in any event will include in the applicable subcontract a license to such Party that is sublicensable to the other Party under this Agreement, of any Patent Rights and Know-How made by such subcontractor resulting from such activities.

(e) Inventorship. Inventorship for inventions made during the course of the performance of this Agreement will be determined in accordance with United States patent laws for determining inventorship.

Section 8.2. Prosecution and Maintenance of the Licensed Patents.

(a) Prosecution by GSK. As between the Parties, GSK will have the first right, and will use diligent, good faith efforts to Prosecute the Licensed Patents and Joint Patents in the Field in the Territory to the extent relating to the Licensed Antibodies or Licensed Products, at GSK’s sole cost and expense through patent counsel or agents of its choice. In addition, GSK shall have the first right to pursue the European Opposition Proceeding, including to submit arguments relating to the European Opposition Proceeding on behalf of Surface to the European Patent Office, at GSK’s sole cost and expense through patent counsel or agents of its choice. GSK will keep Surface reasonably informed via the JPC of all steps with regard to and the status of such Prosecution of such Licensed Patents and Joint Patents and the activities in the European Opposition Proceeding, including by providing Surface with (i) copies of all correspondence and material communications it sends to or receives from any patent office or agency in the Territory relating to such Licensed Patents, Joint Patents and European Opposition Proceeding, (ii) a draft copy of all applications and other documents relating to such Licensed Patents, Joint Patents and European Opposition Proceeding sufficiently in advance of filing to permit reasonable review and comment by Surface and giving due consideration to such comments, and (iii) a copy of applications and other documents as filed, together with notice of its filing date and serial number, relating to such Licensed Patents, Joint Patents and European Opposition Proceeding. Before GSK submits any material filing relating to such Licensed Patents or Joint Patents (including a new patent application) or the European Opposition Proceeding, or a response to such patent authorities with respect to such Licensed Patents, Joint Patents or the European Opposition Proceeding, GSK will provide Surface with a reasonable opportunity to review and comment on such filing or response and will take into account and consider in good faith Surface’s reasonable and timely requests and suggestions regarding the Prosecution of such Licensed Patents and Joint Patents and the activities in the European Opposition Proceeding under this Section 8.2(a). In addition, GSK will provide Surface with copies of all final material filings and responses made to any patent office with respect to the Licensed Patents, the Joint Patents and the European Opposition Proceeding in a timely manner following submission thereof.

30

(b) Step-In Right. If GSK elects not to continue to (i) Prosecute a given Patent Right within the Licensed Patents or Joint Patents in the Field in the Territory pursuant to Section 8.2(a) or (ii) pursue the European Opposition Proceeding, then in each case GSK will give Surface notice thereof within a reasonable period (but not less than [***]) prior to allowing such Patent Rights to lapse or become abandoned or unenforceable or prior to any material deadline in the European Opposition Proceeding, and Surface will have the right to Prosecute such Patent Right within the Licensed Patents or Joint Patents, as applicable or pursue the European Opposition Proceeding. Surface will have the right, but not the obligation, to assume responsibility for continuing the Prosecution of such Patent Right in the Field in such country or pursuing the European Opposition Proceeding and paying any required fees, all at Surface’s sole expense, through patent counsel or agents of its choice. Upon transfer of GSK’s responsibility for Prosecuting any of the Patent Rights within the Licensed Patents or Joint Patents to Surface under this Section 8.2(b), (i) solely with respect to any Patent Right within the Joint Patents, GSK will assign to Surface all of GSK’s rights, title, and interests in and to such Patent Right; (ii) such Patent Right will cease to be Licensed Patents or Joint Patents licensed to GSK under this Agreement; (iii) Surface may, in its sole discretion, Prosecute or abandon such Patent Right; and (iv) GSK will promptly deliver to Surface copies of all necessary files related to the Patent Rights with respect to which responsibility has been transferred and will take all actions and execute all documents reasonably necessary for Surface to assume such Prosecution and defense. Upon transfer of GSK’s responsibility for pursuing the European Opposition Proceeding under this Section 8.2(b), (i) Surface may, in its sole discretion, pursue or abandon efforts related to the European Opposition Proceeding; and (ii) GSK will promptly deliver to Surface copies of all necessary files related to the European Opposition Proceeding with respect to which responsibility has been transferred and will take all actions and execute all documents reasonably necessary for Surface to assume activities relating to the European Opposition Proceeding.

(c) Cooperation in Support of Assignment. In the event that Surface exercises its right to be assigned GSK’s interest in a Joint Patent pursuant to Section 8.2(b), then upon Surface’s request, GSK will provide all further cooperation that Surface reasonably determines is necessary to give effect to such assignment and to ensure Surface the full and quiet enjoyment of such assigned Patent Rights, including executing and delivering further assignments, consents, releases, and other commercially reasonable documentation, and providing good faith testimony by affidavit, declaration, deposition, in person or other proper means, and otherwise assisting Surface in support of any effort by Surface to establish, perfect, defend, or enforce its rights in such assigned Patent Rights.

(d) Cooperation in Prosecution and the European Opposition Proceeding. Each Party will, and will cause its Affiliates to, reasonably cooperate, with the other Party with respect to the Prosecution of Licensed Patents and Joint Patents and activities relating to the European Opposition Proceeding pursuant to this Section 8.2, including providing any necessary powers of attorney, complying with any applicable duty of candor or disclosure with a patent office and executing any other required documents or instruments for such Prosecution.

(e) Prosecution of GSK Patents. GSK will control and be responsible, at its own expense, for the Prosecution of all GSK Patents.

(f) Patent Extensions; Data Exclusivity and Purple Book and Patent Register Listings; Biosimilar Applications.

31

(i) Patent Term Extension. If elections with respect to obtaining patent term extension or supplemental protection certificates or their equivalents in any country with respect to any Licensed Product becomes available, upon Regulatory Approval or otherwise, the Parties will mutually agree on which issued patent to extend, and in any event, the Parties understand and agree that a Licensed Patent or Joint Patent will be extended (including in the U.S. upon Regulatory Approval thereof), if possible, in lieu of any other Patent Right only if such Licensed Patent or Joint Patent would extend longer than such other Patent Right.

(ii) Data Exclusivity, Purple Book and Patent Register Listings. With respect to data exclusivity periods (such as those periods listed in the Purple Book (including any available pediatric extensions) or periods under national implementations of Article 10.1(a)(iii) of Directive 2001/EC/83, and all equivalents in any country), GSK, in consultation with Surface, will seek and maintain all such data exclusivity periods that may be available for any of the Licensed Products. GSK will determine which Licensed Patents and Joint Patents, if any, will be listed with the applicable Regulatory Authorities for any Licensed Product, including all so-called “Patent Register” listings required by certain Governmental Authorities, and all similar listings in any other relevant countries.

(iii) Biosimilar Applications. If either Party receives a copy of an application submitted to the FDA under subsection (k) of Section 351 of the PHSA (a “Biosimilar Application”) naming a Licensed Product as a reference product or otherwise becomes aware that such a Biosimilar Application has been filed (including by the receipt of information disclosed pursuant to Section 351(l)(2) of the PHSA, or in an instance described in Section 351(l)(9)(C) of the PHSA), either Party will, within [***], notify the other Party so that the other Party may seek permission to view the application and related confidential information from the filer of the Biosimilar Application under Section 351(l)(1)(B)(iii) of the PHSA. If either Party receives any equivalent or similar certification, information or notice in any other jurisdiction in the Territory naming a Licensed Product, either Party will, within [***], notify and provide the other Party with copies of such communication. Regardless of the Party that is the “reference product sponsor” for purposes of such Biosimilar Application, (A) GSK will have the first right, after consulting with Surface, to designate pursuant to Section 351(l)(1)(B)(ii) of the PHSA the outside counsel and in-house counsel who will receive confidential access to the Biosimilar Application, (B) GSK will have the first right, after consulting with Surface, to (1) list any Licensed Patents, and any other Patent Rights, as required pursuant to Section 351(l)(3)(A), Section 351(l)(5)(b)(i)(II), or Section 351(l)(7) of the PHSA, (2) respond to any communications with respect to such lists from the filer of the Biosimilar Application, and (3) negotiate with the filer of the Biosimilar Application as to whether to utilize a different mechanism for information exchange than that specified in Section 351(l) of the PHSA; and (C) GSK will have the first right, after consulting with Surface, to identify Licensed Patents and any other Patent Rights, and to respond to communications under any equivalent or similar listing in any other jurisdiction in the Territory. If GSK does not defend a given Patent Right within the Licensed Patents or Joint Patents under this Section 8.2(f)(iii) within [***] (or such shorter period of time before the time limit, if any, set forth in the appropriate Laws in the United States or any other country in the Territory to not waive any statutory rights), or elects not to continue any such defense (in which case it will promptly provide notice thereof to Surface), then Surface will have the right (but not the obligation), at its sole discretion, to defend any such Patent Right.

Section 8.3. Third Party Infringement.

(a) Notice. Each Party will promptly notify the other in writing of any (i) apparent, threatened or actual infringement by a Third Party of any Licensed Patent or Joint Patent, or (ii) unauthorized use or misappropriation of any Licensed Know-How by a Third Party of which it becomes aware, and, in each case, will provide the other Party with all evidence in such Party’s possession or control supporting such infringement or unauthorized use or misappropriation (each, an “Infringement”).

32

(b) GSK Sole Right. As between the Parties, GSK will have the sole right, but not the obligation, using counsel of its choosing and at its sole expense, to institute any Action alleging Infringement of the Licensed Patents or Joint Patents by a Third Party conducting the manufacture, use, marketing or sale of a product falling within the scope of the exclusive license granted to GSK in Section 2.1 (any such Action, an “Infringement Action”). GSK will notify and keep Surface apprised in writing of any such Infringement Action and will consider Surface’s reasonable interests and requests regarding such Infringement Action.

(c) Cooperation. In any Infringement Action brought under the Licensed Patents or Joint Patents pursuant to Section 8.3(b), Surface will, and will cause its Affiliates to, reasonably cooperate with GSK, in good faith, relative to GSK’s efforts to protect the Licensed Patents and Joint Patents and will join such suit as a party, if requested by GSK. Furthermore, GSK will consider in good faith all reasonable and timely comments from Surface on any proposed arguments asserted or to be asserted in litigation related to the enforcement or defense of any such Patent Rights. GSK will have the right to settle any patent infringement litigation with respect to any Licensed Patent under this Section 8.3 in a manner that diminishes the rights or interests of Surface without the consent of Surface (which will not be unreasonably withheld).

(d) Expenses. Subject to Section 8.3(e), GSK will be solely responsible for all expenses arising from a suit or Action against an Infringement Action. For the avoidance of doubt, GSK will not be responsible for Surface’s internal expenses (e.g., FTEs) incurred as a result of Surface’s cooperation with the enforcement Action as provided in this Section 8.3. Surface will be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but Surface will at all times cooperate fully with GSK.

(e) Allocation of Recoveries. Any settlements, damages or monetary awards recovered by either Party pursuant to any Infringement Action with respect to the Licensed Patents or Joint Patents will, after reimbursing the Parties for their reasonable expenses in making such recovery (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses), be retained by the Party that has exercised its right to bring the enforcement action; provided, however, that to the extent that any award or settlement (whether by judgment or otherwise) with respect to a Licensed Patent or Joint Patent is attributable to loss of sales or profits with respect to a Licensed Product, such amount shall be paid to or retained by GSK and treated as “Net Sales” in the Calendar Year in which the money is actually received and any royalties pursuant to Section 7.2 shall be payable by GSK to Surface with respect thereto.

Section 8.4. Claimed Infringement. Each Party will promptly notify the other Party if a Third Party brings any Action alleging patent infringement by GSK or Surface or any of their respective Affiliates or sublicensees with respect to the Development, Manufacture or Commercialization of any Licensed Product (any such Action, an “Infringement Claim”) in the Territory. GSK will have the right, but not the obligation, to control the defense and response to any such Infringement Claim in the Territory, at GSK’s sole cost and expense, and Surface will have the right, at its own expense, to be represented in any such Infringement Claim in the Territory by counsel of its own choice. Upon the request of GSK, Surface will reasonably cooperate with GSK in the reasonable defense of such Infringement Claim. Surface will have the right to consult with GSK concerning any Infringement Claim and to participate in and be represented by independent counsel in any associated litigation. GSK will (a) consult with Surface as to the strategy for the prosecution of such defense, (b) consider in good faith any comments from Surface with respect thereto and (c) keep Surface reasonably informed of any material steps taken and provide copies of all material documents filed, in connection with such defense. GSK will have the right to settle such Infringement Claim on terms deemed reasonably appropriate by it, provided, that, unless any such settlement includes a full and unconditional release from all liability of Surface and does not adversely affect the rights of Surface, any such settlement will be subject to Surface’s prior written consent.

33

Section 8.5. Common Interest. All information exchanged between the Parties regarding the Prosecution of Licensed Patents and Joint Patents under this ARTICLE VIII will be deemed Confidential Information of the disclosing Party. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning the Licensed Patents, the Joint Patents and the European Opposition Proceeding under this ARTICLE VIII, including privilege under the common interest doctrine and similar or related doctrines. Notwithstanding anything to the contrary contained herein, to the extent a Party has a good faith belief that any information required to be disclosed by such Party to the other Party under this ARTICLE VIII is protected by attorney-client privilege or any other applicable legal privilege or immunity, such Party will not be required to disclose such information, and the Parties will in good faith cooperate to agree upon a procedure (including entering into a specific common interest agreement, disclosing such information on a “for counsel eyes only” basis or similar procedure) under which such information may be disclosed without waiving or breaching such privilege or immunity.

Section 9.1. Confidential Information.

(a) Confidentiality Obligation. During the Term and for a period of [***] after any termination or expiration of this Agreement, each Party agrees to, and will cause its Affiliates, its and their sublicensees and subcontractors to, keep in confidence and not to disclose to any Third Party, or use for any purpose, except to exercise its rights or perform its obligations under this Agreement, any Confidential Information of the other Party, without the prior written consent of such disclosing Party. The existence and terms of this Agreement are the Confidential Information of each Party.

(b) Permitted Disclosures. Each Party agrees that it and its Affiliates will provide or permit access to the other Party’s Confidential Information only to the receiving Party’s employees, consultants, subcontractors, advisors and sublicensees, and to the employees, consultants, subcontractors, advisors and sublicensees of the receiving Party’s Affiliates, in each case on a need to know basis who are subject to obligations of confidentiality and non-use with respect to such Confidential Information no less stringent than the obligations of confidentiality and non-use of the receiving Party pursuant to this Section 9.1; provided, however, that each Party will remain responsible for any failure by its Affiliates and its and their sublicensees, and its and its Affiliates’ respective employees, consultants, subcontractors and advisors, to treat such Confidential Information as required under this Section 9.1 as if such Affiliates, employees, consultants, subcontractors, advisors and sublicensees were parties directly bound to the requirements of this Section 9.1.

(c) Confidentiality Limitation. Notwithstanding anything to the contrary herein, each Party may use and disclose the other Party’s Confidential Information as follows: (i) to its Affiliates, bona fide potential or actual collaborators, licensors, Sublicensees, sublicensees, or strategic partners and to employees, directors, agents, consultants, and advisers of such Third Parties, financial advisors, attorneys and accountants, bona fide actual or potential acquisition partners, financing sources or investors and underwriters in all cases on a need to know basis, and under appropriate confidentiality and non-use obligations (which may include professional ethical obligations) no less stringent than those in this Agreement (but of duration customary in confidentiality agreements entered into for a similar purpose); provided, however, that each Party will remain responsible for any failure by any of the foregoing recipients to treat such Confidential Information as required under Section 9.1 as if such recipients were parties directly bound to the requirements of this Section 9.1, (ii) as required by any court governmental body or other Governmental Authority as otherwise required by applicable Laws (including any such disclosures as are required by a Regulatory Authority in connection with seeking Regulatory Approval, Pricing and

34

Reimbursement Approval, import authorization for any Licensed Product in the Territory, or the rules or regulations of the United States Securities and Exchange Commission or similar Regulatory Authority in a country other than the United States or of any stock exchange or listing entity); provided, that, notice is promptly given to the other Party and the disclosing Party cooperates with reasonable requests from the other Party to seek a protective order or other appropriate remedy to protect the Confidential Information, or (iii) to a patent authority as may be reasonably necessary or useful for purposes of obtaining Patent Rights as permitted by this Agreement; provided that reasonable measures shall be taken to assure confidential treatment of such information, to the extent such protection is available. Notwithstanding anything to the contrary contained in this ARTICLE IX, Confidential Information that is permitted or required to be disclosed will remain otherwise subject to the confidentiality and non-use provisions of Section 9.1(b) and this Section 9.1(c). If either Party concludes that a copy of this Agreement must be filed with the United States Securities and Exchange Commission or similar Regulatory Authority in a country other than the United States, then such Party will, within a reasonable time (and in no event less than [***]) prior to any such filing, provide the other Party with a copy of this Agreement showing any provisions hereof as to which the Party proposes to request confidential treatment and will provide the other Party with an opportunity to comment on any such proposed redactions and to suggest additional redactions. The Party filing the Agreement will take the other Party’s reasonable comments into consideration before filing such agreement and use reasonable efforts to have terms identified by such other Party afforded confidential treatment by the applicable Regulatory Authority.

(d) When transferring Confidential Information, all communications between GSK and Surface will use encryption methods agreed to by the Parties. Upon discovering any suspected or actual unauthorized disclosure, loss or theft of Confidential Information (a “Data Security Breach”) Surface will send an e-mail to [***] notifying GSK, and upon discovering any suspected or actual Data Security Breach, GSK will send an e-mail to [***], notifying Surface. The Parties shall work with each other in good faith to identify a root cause and remediate the Data Security Breach.

Section 9.2. Publicity and Press Release. The Parties acknowledge the importance of supporting each other’s efforts to publicly disclose results and significant Developments regarding Licensed Products in the Field in the Territory, and each Party may make such disclosures from time to time, subject to the terms and conditions of this Agreement, including this Section 9.2. Such disclosures may include achievement of milestones, significant events in the Development process with respect to Licensed Products, or Commercialization activities with respect to Licensed Products.

(a) The Parties have agreed upon the content of a press release which shall be issued by Surface substantially in the form attached hereto as Schedule 9.2, promptly after the Effective Date. Except for disclosures permitted in accordance with Section 9.1(b), Surface shall not issue any other public announcement, press release or other public disclosure regarding this Agreement, its subject matter or any amendment hereto without GSK’s prior written consent, except for any such disclosure that (i) repeats any information regarding this Agreement, its subject matter or any amendment hereto that has already been publicly disclosed by either Party in accordance with this Section 9.2, provided that such information remains accurate as of such time and provided the frequency and form of such disclosure are reasonable, or (ii) is, in the opinion of Surface’s counsel, required by applicable Laws or the rules of a stock exchange on which the securities of Surface are listed (or to which an application for listing has been submitted), provided, that disclosure under this clause (ii) shall include the minimum amount of Confidential Information required by such applicable Laws, and Surface will use reasonable efforts to seek confidential treatment of Confidential Information to be included in such disclosures. In the event Surface is, in the opinion of its counsel, required by applicable Laws or the rules of a stock exchange on which its securities are listed (or to which an application for listing has been submitted) to make such a public disclosure, Surface shall submit the proposed disclosure in writing to GSK as far in advance as reasonably practicable (and in no event less than [***] prior to the anticipated date of disclosure) so as to provide a reasonable

35

opportunity to comment thereon. For clarity, GSK and its Affiliates and its and their Sublicensees shall have the right to publicly disclose research, development and commercial information (including with respect to regulatory matters) regarding the Licensed Antibody and Licensed Product; provided such disclosure is subject to the provisions of Section 9.1 with respect to Surface’s Confidential Information.

(b) The principles to be observed in such disclosures will include accuracy, compliance with applicable Laws and regulatory guidance documents and the need to keep investors informed regarding the business of the Party making such public disclosure. Nothing in this Section 9.2 will restrict a Party from making a disclosure required by Laws as reasonably determined by such Party’s counsel, including disclosures required by any Laws relating to the public sale of securities; provided, however, that such disclosure will include the minimum amount of Confidential Information required by such applicable Laws, and the Parties will use reasonable efforts to seek confidential treatment of Confidential Information to be included in such disclosures.

Section 9.3. Scientific Publications.

(a) As between the Parties, GSK shall control all scientific publications relating to all activities undertaken under this Agreement for the relevant Licensed Antibodies and Licensed Products, which publications shall not require the prior written approval of Surface. If GSK or its employees or consultants (such as clinical investigators) wish to publish or publicly present any information about a Licensed Product or the results of any activities relating to the research or development of Licensed Antibodies, which publication contains any of Surface’s Confidential Information, it shall deliver to Surface a copy of the proposed written publication or an outline of an oral disclosure at least [***] ([***] in the case of abstracts) prior to submission for publication or presentation. Surface will respond in writing promptly and in no event later than [***] ([***] in the case of abstracts) after receipt of the proposed material and shall have the right to propose modifications to the publication or presentation for confidentiality reasons, or request a reasonable delay in publication or presentation in order to protect patentable information. In the event that Surface identifies patentable subject matter in the proposed material, GSK agrees not to submit such publication or to make such presentation that contains such information for a period of up to [***] in order to seek patent protection for any material in such publication or presentation. If Surface reasonably requests modifications to the publication or presentation to prevent disclosure of Surface’s Confidential Information, GSK shall edit such publication to prevent the disclosure of such Confidential Information prior to submission of the publication or presentation.

(b) All publications made by GSK relating to any Licensed Antibody or Licensed Product will be prepared, presented, and published in accordance with pharmaceutical industry accepted guidelines.

(c) In addition to the foregoing, subject to this Section 9.3, GSK shall have the right at any time during and after the Term to (a) publish the results or summaries of results of all Clinical Studies, observational studies and other studies such a meta analyses, conducted with respect to any and all Licensed Antibodies and Licensed Products in any clinical trial register maintained by GSK or its Affiliates and the protocols of such Clinical Studies on www.clinicaltrials.gov or in each case publish the results, summaries or protocols of such Clinical Studies or other studies on such other websites or repositories or at scientific congresses and in peer-reviewed journals within such timescales as required by applicable Laws or GSK’s or its Affiliate’s internal policies and procedures, irrespective of the outcome of such Clinical Studies; (b) make information from Clinical Studies or other studies conducted by or on behalf of GSK with respect to Licensed Antibodies or Licensed Products available under its Data Sharing Initiative; and (c) make any other public disclosures of Clinical Data that become required of GSK due to its internal policies and procedures or applicable Laws.

36

(d) Each publication made in accordance with this Section 9.3 shall not be a breach of the confidentiality provisions set forth in Section 9.1.

Section 9.4. Equitable Relief. Given the nature of the Confidential Information and the competitive damage that could result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages will not be a sufficient remedy for any breach of this ARTICLE IX. In addition to all other remedies, and notwithstanding the provisions of ARTICLE XIV, a Party will be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this ARTICLE IX.

Section 13.3. Early Termination.

(a) Termination for Material Breach. Upon (i) any material breach of this Agreement by Surface or (ii) any material breach of this Agreement by GSK (the Party so allegedly breaching being the “Breaching Party”), the other Party (the “Non-Breaching Party”) will have the right, but not the obligation, to terminate this Agreement in its entirety by providing [***] written notice to the Breaching Party with respect to any breach of any payment obligation under this Agreement and [***] written notice to the Breaching Party with respect to any other breach, which notice will, in each case (A) expressly reference this Section 13.3(a), (B) reasonably describe the alleged breach which is the basis of such termination, and (C) clearly state the Non-Breaching Party’s intent to terminate this Agreement if the alleged breach is not cured within the applicable cure period. The termination will become effective at the end of the notice period unless the Breaching Party cures such breach during such notice period; provided, that if there is a good faith dispute with respect to the existence of a material breach or whether such material breach has been cured, and if such alleged breach or failure to cure is contested in good faith by the Breaching Party in writing within [***] of the delivery of the breach notice, then the dispute resolution procedure pursuant to ARTICLE XIV, may be initiated by either Party to determine whether a material breach or a failure to cure has actually occurred. If either Party so initiates the dispute resolution procedure, then the applicable cure period (and the corresponding termination of this Agreement, in whole or in part), shall be tolled until such time as the dispute is resolved pursuant to ARTICLE XIV. Notwithstanding the foregoing, if the breach and failure to cure contemplated by this Section 13.3(a) is with respect to GSK’s breach of its diligence obligations set forth in Sections 4.1 and 5.2 with respect to one or more (but not all) of the countries in the Territory, Surface shall not have the right to terminate this Agreement in its entirely, but shall have the right to terminate this Agreement solely with respect to the country(ies) to which such breach and failure to cure applies.

(b) Termination by GSK for Convenience. GSK will have the right to terminate this Agreement in its entirety for convenience, without cause, and for any or no reason (a) on not less than [***] prior written notice to Surface if such notice is provided prior to GSK’s receipt of the first Regulatory Approval for a Licensed Product, and (b) on not less than [***] prior written notice to Surface if such notice is provided following GSK’s receipt of the first Regulatory Approval for a Licensed Product.

(c) Termination for Bankruptcy.

(d) Patent Challenge.

(i) Except to the extent that this Section 13.3(d) is unenforceable under the Law of the applicable jurisdiction where the applicable Licensed Patents are pending or issued, Surface has the right to terminate this Agreement upon written notice to GSK in the event that GSK or any of its Affiliates or its or their Sublicensees directly or indirectly challenges in a legal or administrative proceeding the patentability, enforceability or validity of any Licensed Patents (a “Patent Challenge”); provided that (A) this Section 13.3(d) will not apply to any such Patent Challenge that is first made by GSK or any of its Affiliates or its or their Sublicensees in defense of a claim of patent infringement brought by Surface under the applicable Licensed Patents, (B) with respect to any Affiliate or Sublicensee, Surface will not have the right to terminate this Agreement under this Section 13.3(d) if GSK (1) causes such Patent Challenge to be terminated or dismissed (or in the case of ex-parte proceedings, multi-party proceedings, or other Patent

43

Challenges in which the challenging party does not have the power to unilaterally cause the Patent Challenge to be withdrawn, causes such Affiliate or Sublicensee to withdraw as a party from such Patent Challenge and to cease actively assisting any other party to such Patent Challenge), or (2) terminates such Sublicensee’s sublicense to the Licensed Patents being challenged by the Affiliate or Sublicensee, in each case, within [***] of Surface’s notice to GSK under this Section 13.3(d).

(ii) In lieu of exercising its rights to terminate under this Section 13.3(d), Surface may elect upon written notice [***], which election will be effective retroactively to the date of the commencement of the Patent Challenge.

(iii) GSK acknowledges and agrees that this Section 13.3(d) is reasonable, valid and necessary for the adequate protection of Surface’s interest in and to the Licensed Patents, and that Surface would not have granted to GSK the licenses under those Licensed Patents, without this Section 13.3(d). Surface will have the right, at any time in its sole discretion, to strike this Section 13.3(d) (or any portion thereof) from this Agreement, and Surface will have no liability whatsoever as a result of the presence or absence of this Section 13.3(d) (or any struck portion thereof).

(e) Termination for Cessation of Development. Without prejudice to any other remedies available to it at law or in equity (including for any breach of the terms hereof), if (i) GSK does not conduct, or cause to be conducted, or otherwise ceases or abandons, material Development activities with respect to Licensed Antibodies and Licensed Products for a period of [***] at any time during the Term or (ii) GSK has not commenced any material Development activities with respect to any Licensed Antibody or Licensed Product on or after the date that is the [***] anniversary of the Effective Date (each, a “Cessation of Development”), then, in each case ((i) and (ii)), Surface will have the right to terminate this Agreement in its entirety with [***] written notice to GSK, unless GSK cures such Cessation of Development during such notice period; provided, that if there is a good faith dispute with respect to the existence of a Cessation of Development or whether such Cessation of Development has been cured, and if such alleged Cessation of Development or failure to cure is contested in good faith by GSK in writing within [***] of the delivery of the notice thereof, then the dispute resolution procedure pursuant to ARTICLE XIV, may be initiated by either Party to determine whether a Cessation of Development or a failure to cure has actually occurred. If either Party so initiates the dispute resolution procedure, then the applicable cure period (and the corresponding termination of this Agreement, in whole or in part), shall be tolled until such time as the dispute is resolved pursuant to ARTICLE XIV. Notwithstanding the foregoing, the abandonment or cessation of material Development activities by GSK with respect to Licensed Antibodies and Licensed Product as described in clauses (i) and (ii) shall not be deemed a Cessation of Development to the extent any such abandonment or cessation is the result of [***].

(f) Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by GSK or Surface are and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction.

44

this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party. The Parties acknowledge and agree that payments made under Section 7.1 shall not (x) constitute royalties within the meaning of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction or (y) relate to licenses of intellectual property hereunder.

ARTICLE XIV

DISPUTE RESOLUTION

Section 14.1. Dispute Resolution; Escalation. The Parties recognize that disputes as to certain matters arising out of or in connection with this Agreement may arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising out of or in connection with this Agreement in an expedited manner by mutual cooperation. To accomplish this objective, any and all disputes between the Parties arising out of or in connection with this Agreement will first be referred to the Senior Officers for resolution and the Senior Officers will attempt to resolve the matter in good faith.

Section 14.2. Mediation. If the Parties’ Senior Officers are unable for any reason to resolve a dispute within [***] of referral of the dispute to them, then the Parties agree that they shall try in good faith to resolve the dispute by referring it for confidential mediation under the CPR Mediation Procedure in effect at the start of mediation, before resorting to arbitration as set forth in Section 14.3. If the Parties cannot agree on a mediator within [***] after the dispute was referred to mediation, the mediator shall, upon request by either Party, be appointed by CPR pursuant to CPR Mediation Procedure. The cost of mediator shall be borne equally by the Parties.

Section 14.3. Arbitration. Except as set forth in this Section 14.3, each dispute, difference, controversy or claim arising in connection with or related or incidental to, or question occurring under, this Agreement or the subject matter hereof that cannot be resolved pursuant to Section 14.1 and Section 14.2 will be referred to and finally resolved by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (the “Rules”). Arbitration proceedings may be commenced by either Party by notice to the other Party. Within [***] after the institution of the arbitration proceedings, each Party will appoint one (1) arbitrator with the third arbitrator to be selected by mutual agreement of the two (2) arbitrators appointed by the Parties, and each arbitrator will have significant experience in the biopharmaceutical industry. If the two initial arbitrators are unable to select a third arbitrator within [***], the third arbitrator will be appointed in accordance with the Rules. Unless otherwise agreed by the Parties, all such arbitration proceedings will be held in New York, New York; provided, however, that proceedings may be conducted by videoconference or telephone conference call with the consent of the Parties and the arbitrator(s). All arbitration proceedings will be conducted in the English language. The arbitrators will consider grants of equitable relief and orders for specific performance as co-equal remedies along with awards of monetary damages. The arbitrators will have no authority to award punitive damages. The allocation of expenses of the arbitration, including reasonable attorney’s fees, will be determined by the arbitrators, or, in the absence of such determination, each Party will pay its own expenses. The Parties hereby agree that the arbitrators have authority to issue rulings and orders regarding all procedural and evidentiary matters that the arbitrators deem reasonable and necessary with or without petition therefore by the Parties as well as the final ruling and judgment. All rulings by the arbitrators will be final. Notwithstanding any contrary provision of this Agreement, any Party may seek equitable measures of protection in the form of attachment of assets or injunctive relief (including specific performance and injunctive relief) in any matter relating to the proprietary rights and interests of either Party from any court of competent jurisdiction, pending a decision by the arbitral tribunal in accordance with this Section 14.3). The Parties hereby exclude any right of appeal to any court on the merits of such matter. The provisions of this Section 14.3 may be enforced and judgment on the award (including equitable remedies) granted in

47

any arbitration hereunder may be entered in any court having jurisdiction over the award or any of the Parties or any of their respective assets. Except to the extent necessary to confirm an award or as may be required by Laws, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties as if any of the foregoing was the Confidential Information of each Party. The Parties agree that, in the event of a dispute over the nature or quality of performance under this Agreement, neither Party may terminate this Agreement until final resolution of the dispute through arbitration or other judicial determination. Nothing in this Section 14.3 will preclude either Party from seeking interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding.

Section 14.4. Notwithstanding the Parties’ agreement to arbitrate, unless the Parties agree in writing in any particular case, claims and disputes between the Parties relating to or arising out of, or for which resolution depends in whole or in part on a determination of the interpretation, scope, validity, enforceability or infringement of, Patent Rights or of any Trademark rights relating to any Licensed Products will not be subject to arbitration under this Agreement, and the Parties may pursue whatever rights and remedies may be available to them under law or equity, including litigation in a court of competent jurisdiction, with respect to such claims and disputes. All questions concerning (a) inventorship of Patent Rights under this Agreement will be determined in accordance with Section 8.1 and (b) the construction or effect of Patent Rights or with respect to Trademarks, will be determined in accordance with the Laws of the country or other jurisdiction in which the particular patent within such Patent Rights or the Trademark has been filed or granted, as the case may be.

49

Section 15.4. Severability. In the event that one or more provisions of this Agreement is held invalid, illegal or unenforceable in any respect, then such provision will not render any other provision of this Agreement invalid or unenforceable, and all other provisions will remain in full force and effect and will be enforceable, unless the provisions that have been found to be invalid or unenforceable will substantially affect the remaining rights or obligations granted or undertaken by either Party. The Parties agree to attempt to substitute for any invalid or unenforceable provision a provision which achieves to the greatest extent possible the objectives of the invalid or unenforceable provision.

Section 15.5. Integration. This Agreement, together with all schedules and exhibits attached hereto, constitutes the entire agreement between the Parties with respect to the subject matter of this Agreement and supersedes all previous arrangements between the Parties with respect to the subject matter hereof, whether written or oral, including, effective as of the Effective Date, the Prior CDA (provided that all information disclosed or exchanged under such agreement will be treated as Confidential Information hereunder).

Section 15.6. Waivers and Amendments. The failure of any Party to assert a right under this Agreement or to insist upon compliance with any term or condition of this Agreement will not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party. The exercise by any Party of any right or election under the terms or covenants herein will not preclude or prejudice any Party from exercising the same or any other right it may have under this Agreement, irrespective of any previous action or proceeding taken by the Parties hereunder. Notwithstanding the authority granted to the JDC under this Agreement, (a) no waiver will be effective unless it has been given in writing and signed by the Party giving such waiver, and (b) no provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party.

For all purposes, and notwithstanding any other provision of this Agreement to the contrary, each Party’s legal relationship under this Agreement to the other Party will be that of independent contractor, and the relationship between the two Parties will not constitute a partnership, joint venture, or agency, including for all tax purposes, except as otherwise required by applicable Law.
