In the event that Tibotec does not provide any Tibotec Regulatory Documentation or such other requested information, or does not provide the consent required pursuant to Section 4.3(c) to permit Gilead to obtain or use any such information, then, to the extent that such information is reasonably required for Gilead to perform its obligations hereunder with respect to one or more country(ies) in the Territory, Gilead shall not be obligated to perform such obligations with respect to such country(ies).

(b) Regulatory Documentation for use in the Tibotec Countries. Reasonably promptly following the later of (i) filing of the NDA or the authorization for marketing approval with the European Commission for the Combination Product, or (ii) the date on which Tibotec first becomes the Selling Party with respect to any country in the Territory, Gilead shall provide Tibotec the CTD for use by Tibotec in connection with obtaining and maintaining Approvals for

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

the Combination Product in the Field in the Tibotec Countries, and shall thereafter reasonably promptly provide Tibotec with any updates by Gilead to the CTD. Tibotec shall include the CTD in each Drug Approval Application (to the extent required to comply with the requirements for such Drug Approval Application) filed to obtain and maintain Approvals in the Field for the Combination Product in the Tibotec Countries. The CTD shall be used by Tibotec solely to obtain Approvals for the Combination Product in the Field in the Tibotec Countries. Tibotec’s regulatory filings with the Regulatory Authorities, including Drug Approval Applications, with respect to the Combination Product in the Tibotec Countries shall be consistent with the CTD. Tibotec shall, to the extent required by Applicable Law or otherwise reasonably requested by Gilead, exercise Commercially Reasonable Efforts to update any such filings promptly to reflect any updates to the CTD as are provided by Gilead to Tibotec from time to time pursuant to this Section 4.3(b). Gilead shall provide electronic versions of the CTD (including any such updates) to Tibotec in a mutually agreed-upon format for the purpose of expediting Tibotec’s activities in preparing and filing Regulatory Documentation for the Tibotec Countries.

(c) Additional Regulatory Documentation Provided by Either Party Following Approval. Notwithstanding anything herein to the contrary, except in the case of the FDA and the EMEA, neither Party shall have any obligation hereunder to provide to the other Party or any Regulatory Authority, in connection with any filings to obtain Approval of the Combination Product in the Field in the Territory, any information relating to such Party’s (or its Affiliates’) APIs, Single Agent Product(s) or Double Agent Product, as the case may be, the disclosure of which such Party reasonably believes may harm its or its Affiliates’ business interests with respect to such APIs, Single Agent Product(s) or Double Agent Product. Notwithstanding the foregoing, once the Selling Party has obtained Approval for the Combination Product in the Field in a country, the non-Selling Party may not withhold Regulatory Documentation or other information related to the Combination Product in the non-Selling Party’s Control that the Selling Party reasonably requires to comply with Applicable Law. Except as otherwise expressly authorized by the non-Selling Party, the Selling Party (and its Affiliates) shall have the right to use any additional information related to the Combination Product provided or made available pursuant to the foregoing sentence (and not pursuant to any other provision hereunder) solely to the extent reasonably necessary to comply with Applicable Law (solely for regulatory purposes contemplated by this Agreement or any Ancillary Agreement).

4.4 Regulatory Filings and Communication.

(a) MA Holder. With respect to each country in the Territory, unless prohibited by Applicable Law, Gilead, or its designated Affiliate or Third Party Distributor, shall hold the marketing authorization with respect to the Combination Product with respect to such country. In those countries in which Tibotec, as the Selling Party, or its designated Affiliate or Third Party Distributor, is required by Applicable Law to hold the marketing authorization, it shall hold the marketing authorization.

(b) Responsibilities With Respect to Combination Product Regulatory Filings. Subject to Section 4.3 and the remainder of this Section 4.4, the Selling Party with respect to each country in the Territory, on behalf of the applicable MA Holder with respect to such country, with the cooperation of the non-Selling Party as reasonably required, shall have primary responsibility for preparing and filing all necessary Regulatory Documentation and for acting as liaison for all communications with the Regulatory Authorities in such country for the purpose of obtaining and maintaining Approval for the Combination Product in the Field in such country, including, subject to clause (ii) below, with respect to any changes to the Product Label and Insert for the Combination Product. Notwithstanding anything to the contrary in this Agreement, each Party shall be responsible for preparing any Regulatory Documentation or other materials with respect to any Clinical Trial that it conducts (either solely or with one or more Third Parties) pursuant to this Agreement.

(i) Discussion of Single Agent Products or Double Agent Product. Notwithstanding anything contained in this Agreement to the contrary, at any meeting with, or any communication to, Regulatory Authorities in the Territory concerning the Combination Product, the Selling Party shall not engage in any substantive discussions pertaining to the other Party’s Single Agent Product(s) or Double Agent Product or the API contained therein, without such other Party’s prior written consent.

(ii) Label Change for Single Agent Products or Double Agent Product. If any communications from Regulatory Authorities in the Territory regarding potential changes to any Product Label and Insert for the Combination Product in the Territory are reasonably expected to lead to a label change for a Party’s Single Agent Product(s) or Double Agent Product, as the case may be, and are not reasonably expected to lead to a label change for the other Party’s Single Agent Product(s) or Double Agent Product, as the case may be, then, notwithstanding anything in this Agreement to the contrary, the affected Party shall take the lead (in coordination with the Selling Party, if such Party is not the Selling Party) in dealing with such Regulatory Authorities on such matter.

(iii) SDEA. Notwithstanding the foregoing, after the SDEA has been entered into pursuant to Section 13, the Party which has responsibility for communications with Regulatory Authorities in a country relating to routine safety-related submissions (e.g., individual case reports) pursuant to the SDEA, shall have the right to communicate (or to cause one or more of its Affiliates or Third Party Distributors to communicate) with Regulatory Authorities in such country in the Territory concerning such submissions in accordance with the terms of the SDEA in a manner consistent with any determinations with respect to such communications made pursuant to the SDEA.

(c) Price Approvals. Notwithstanding anything in this Section 4.4 to the contrary, this Section 4.4 shall not govern the obtaining and maintaining of pricing and reimbursement approvals in the Territory with respect to the Combination Product, or any communications with any Regulatory Authorities with respect to the foregoing matters. For clarity, such approvals and communications shall be governed by Section 7.

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(d) Regulatory Matters Concerning Single/Double Agent Products. Nothing contained in this Section 4.4 shall prohibit or restrict either Party from communicating with the Regulatory Authorities on matters relating to the Exploitation of any of its respective Single Agent Product(s), Double Agent Product or pharmaceutical products other than the Combination Product. Each Party shall promptly notify the other Party of any change proposed by the notifying Party to any Product Label and Insert for its Single Agent Product(s) or Double Agent Product in the Territory that is substantive in nature, where such proposed change is likely to have an impact on any Product Label and Insert for the Combination Product, reasonably in advance of the anticipated filing date of such proposed change, by furnishing the other Party with the text of the proposed change and a summary description of the data supporting or basis for such proposed change. In addition, promptly after the filing of such proposed change with the applicable Regulatory Authorities in the Territory, the Party that has provided such notice shall furnish the other Party with the text of the proposed change as filed. Any resulting filing with respect to the Product Label and Insert for the Combination Product shall be governed by Section 4.4(b) and any documentation required in connection with such filing shall be exchanged to the extent and in the manner set forth in Section 4.3.

(e) Regulatory Matters Concerning a Party’s Compliance with Applicable Law. Notwithstanding anything herein to the contrary, as between the Parties, regardless of which Party is the Selling Party, each Party shall have sole responsibility for any submissions to, or communications with, any Regulatory Authority in the Territory with respect to any matter relating to such Party’s or any of its Affiliates’, subcontractors’ or Third Party Distributor’s compliance with Applicable Law in connection with its performance of such Party’s Commercialization Activities, unless such submissions or communications are made in connection with obtaining or maintaining the applicable Drug Approval Application (in which case the applicable provisions of this Section 4.4 shall control).

(f) Activities in the EU. This Section 4.4 shall apply to the preparing and filing of all necessary Regulatory Documentation and communications with the Regulatory Authorities of the European Union, including the EMEA, as if the European Union were a “country” for purposes of this Section 4.4.

4.5 Records. Each Party shall maintain, or cause to be maintained, records with respect to its activities pursuant to this Section 4 in material compliance with Applicable Law. Such records shall be retained for at least (a) three (3) years or (b) such longer period as may be required by Applicable Law.

4.6 Regulatory Costs and Expenses. With respect to each country in the Territory, each Party shall bear its own costs and expenses relating to the Combination Product Regulatory Activities and regulatory filings for the Combination Product in such country. Tibotec or its applicable Affiliate shall bear all costs and expenses relating to the TMC278 Product Regulatory Activities and any regulatory filings relating to the TMC278 Product.

SECTION 5

MEDICAL AFFAIRS; CONFERENCES

5.1 Product Information; Medical Affairs and Medical Communications.

(a) Generally. Subject to this Section 5, Gilead and Tibotec shall determine independently how to utilize and deploy their respective medical science liaisons for activities relating to the Combination Product, subject to the referral provisions set forth in Annex V.

(b) Responses to Medical Inquiries. Each Party shall (i) apply its standard guidelines and procedures for determining and providing appropriate responses to medical inquiries about the Combination Product in the Territory, including assigning responsibilities for medical communications and (ii) to the extent determined appropriate by a Party, develop a set of standard response documents for use by such Party in responding to medical inquiries about the Combination Product in the Territory. Each Party shall ensure that any such response procedures and standard response documents comply with Applicable Law. Each Party may make its standard response documents for the Territory available to the other Party and the other Party may, in its sole discretion, elect to use or adapt the providing Party’s standard response documents in connection with the receiving Party’s response to medical inquiries in the Territory, subject to the receiving Party’s ensuring that such documents that it elects to use or adapt comply with Applicable Law. If at any time a Party has concerns about the other Party’s procedures for responding to medical inquiries about the Combination Product in the Territory or standard response documents for use in responding to medical inquiries about the Combination Product in the Territory, the concerned Party may refer the matter to the Alliance Managers and the Alliance Managers shall facilitate discussion and resolution of such concerns.

5.2 Conferences and Symposia. Tibotec shall not participate in or sponsor any formal presentation or panel with respect to the Combination Product at any conference or symposia without the prior written consent of Gilead; provided, however, that Tibotec may participate in or sponsor such presentations or panels at conferences or symposia (other than international meetings) in the Tibotec Countries.

SECTION 6

COMMERCIALIZATION ACTIVITIES

6.1 Distribution Rights in the Option Countries and Related Matters. Tibotec shall have the right to negotiate to become the Selling Party with respect to any Option Country. In the event that either Party desires to become the Selling Party with respect to any Option Country(ies), such Party shall notify the other Party in writing (an “Option Notice”). Promptly following receipt of an Option Notice by either Party, the Parties shall exclusively negotiate in good faith, for a period of one hundred eighty (180) days, terms of an agreement pursuant to which Gilead shall (a) appoint Tibotec as the exclusive distributor of the Combination Product in the Option Country(ies) identified in the Option Notice in the Field and grant Tibotec the right to Distribute (either itself or through its Third Party Distributors) the Combination Product in such

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Option Country(ies) in the Field, in each case during the term of this Agreement, and (b) in connection therewith, sell to Tibotec the Combination Product in bulk or unlabeled bottle form (each such agreement, a “Tibotec Distributor Agreement”) or, if Tibotec does not desire to serve as a distributor of the Combination Product in such country, amendments to this Agreement that would allow Gilead to be the Selling Party with respect to such country. In the event that, following such period of exclusive negotiation, the Parties enter into a Tibotec Distributor Agreement with respect to any Option Country(ies) identified in the Option Notice, Tibotec shall become the Selling Party with respect to such country(ies). Neither Party may conduct Commercialization Activities in any Option Country prior to becoming the Selling Party with respect to such Option Country pursuant to this Section 6.1 or otherwise by mutual agreement of the Parties in writing.

6.2 Commercialization Activities.

(a) Diligence. Subject to the terms and conditions of this Agreement, the Selling Party shall have the right to perform Commercialization Activities with respect to the countries for which it is the Selling Party. The Selling Party shall use Commercially Reasonable Efforts to perform Commercialization Activities, including Premarket Launch Activities, with respect to the United States and the European Union. Notwithstanding the foregoing, in no event shall the Selling Party have the right to perform or be required to perform any Commercialization Activities (other than (i) Premarket Launch Activities and (ii) seeking pricing and reimbursement approvals in anticipation of Launch) unless and until Launch in such country is permitted by Section 7 and Annex R (each such country, a “Permitted Launch Country”). In determining whether the Selling Party is using Commercially Reasonable Efforts to perform Commercialization Activities in a particular country, it shall be taken into account whether the Combination Product is priced competitively within such country. To the extent that Section 7 and Annex R do not permit the Selling Party to set a competitive price (without reducing its portion of the revenue of the Combination Product), or, in a Price Approval Country, the Selling Party is unable to obtain a competitive price, the Selling Party shall not be deemed to have breached its obligation to use Commercially Reasonable Efforts if it does not use efforts equivalent to those that would have been deemed to constitute Commercially Reasonable Efforts had the price of the Combination Product been competitive and if it is not possible to set such a competitive price, the Selling Party shall have the right to suspend some or all of its Commercialization Activities, in its sole discretion.

(b) Specific Commercialization Obligations. Without limitation of Section 6.2(a), Gilead agrees to the following solely with respect to each of the Major Markets:

(i) Commencing as of the later of Approval or Launch of the Combination Product in the applicable country until the earlier of [*], whichever comes first (such period, the “Launch Period”), Gilead shall ensure (and certify in writing each Calendar Quarter) that the incentive compensation provided by Gilead each Calendar Quarter with respect to the Combination Product to each of the sales representatives of Gilead who are responsible for Detailing the Combination Product in one or more Major Market satisfies the following criteria:

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

the incentive compensation payable to each such sales representative if such sales representative achieves his or her target sales for such Calendar Quarter with respect to the Combination Product shall [*] if he or she achieves his or her target sales for such Calendar Quarter for all of the products for which such sales representative is responsible for detailing.

(ii) For each Major Market, Gilead shall (A) achieve [*] Aided Physician Awareness (as defined in Annex F) on or about the first anniversary of the later of Approval or Launch of the Combination Product in such country, (B) achieve [*] Aided Physician Awareness on or about the second anniversary of such Launch or Approval, as applicable and (C) maintain [*] Aided Physician Awareness for the remainder of the Launch Period (which level of Aided Physician Awareness, unless waived by Tibotec in writing, shall be demonstrated by Gilead annually on or about each subsequent anniversary of such Launch or Approval, as applicable, during the Launch Period). The method for determining whether the applicable level of Aided Physician Awareness has been achieved is set forth on Annex F.

(iii) In each Major Market, for each Detailing Year (as defined below), through the Calendar Quarter that includes the last day of the Launch Period, Gilead shall perform the number of Details of the Combination Product, [*], as set forth on Annex F. Gilead shall use Commercially Reasonable Efforts to ensure that the number of such Details for each Major Market in each Calendar Quarter of each Detailing Year is no less than [*] of the number of Details required for such Detailing Year. Gilead shall certify in writing its compliance with this Section 6.2(b)(iii) on a quarterly basis. A “Detailing Year” for a Major Market shall mean (A) in the case of the first Detailing Year, the period beginning on the first day of the first full Calendar Quarter after the later to occur of the Launch or Approval of the Combination Product in such Major Market through the end of the Calendar Year in which such Launch or Approval, as applicable, occurs (in which case, Gilead’s obligations under this paragraph with respect to such Detailing Year shall be prorated accordingly), and (B) in the case of each other Detailing Year, the Calendar Year following the prior Detailing Year, until the end of the Calendar Quarter that includes the last day of the Launch Period (and in the case of the last Detailing Year with respect to a Major Market, Gilead’s obligations under this paragraph with respect to such Detailing Year shall be prorated accordingly).

(iv) Gilead acknowledges and agrees that Gilead’s achievement of each and all of the requirements in subsections (i) through (iii) of this Section 6.2(b) (the “Specific Targets”) with respect to each Major Market country goes to the root of this Agreement and is an essential element of this Agreement, and that Gilead’s failure to substantially achieve each or any of the Specific Targets with respect to a Major Market country is a Material Breach that entitles Tibotec to terminate this Agreement pursuant to Section 19.4 if Gilead fails to cure such failure as provided in Section 19.4 or, with respect to each Initial Specific Target Breach, Section 6.2(b)(v).

(v) With respect to each Initial Specific Target Breach, Tibotec agrees that Gilead shall be deemed to have cured such failure if Gilead complies with the following (each a “Specific Cure”) with respect to the applicable failure:

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(A) in the case of a breach of Section 6.2(b)(i) with respect to a Major Market country, for a number of consecutive Calendar Quarters equal to the number that Gilead was so in breach, starting with the Calendar Quarter immediately following the Calendar Quarter in which Gilead received written notice of such breach, Gilead complies (and on a quarterly basis certifies its compliance in writing) with the requirements of Section 6.2(b)(i) in all respects, except that the incentive compensation with respect to the Combination Product for such period shall be [*].

(B) in the case of a breach of Section 6.2(b)(ii) with respect to a Major Market country, no later than ninety (90) days following Gilead’s receipt of notice of such breach, Gilead achieves [*] Aided Physician Awareness in accordance with Annex F; and

(C) in the case of a breach of Section 6.2(b)(iii) with respect to a Major Market country for a given Detailing Year (or a given Calendar Quarter within a Detailing Year), no later than ninety (90) days following Gilead’s receipt of notice of such breach, Gilead conducts in such country a number of Details of the Combination Product, in either the [*], equal to the number of Details by which Gilead fell short of its obligations under Section 6.2(b)(iii) with respect to such country and such Detailing Year (or Calendar Quarter, as applicable); provided, that the Details performed by Gilead in curing said breach shall not count toward Gilead’s fulfillment of its Detailing obligations under Section 6.2(b)(iii) for any Calendar Quarter or Detailing Year other than the Calendar Quarter and Detailing Year in which the breach occurred;

provided, however, that with respect to each Major Market country, once Gilead successfully completes a Specific Cure with respect to a breach of subsection (i), (ii) or (iii) of this Section 6.2(b), [*], and the [*] shall be governed by the general principles governing cure set forth in Section 19.4 and not by this subsection 6.2(b)(v).

(vi) Notwithstanding the foregoing, if the Target Product Profile is not achieved in the applicable country then the obligations set forth in this Section 6.2(b) shall not apply to such country and the Parties shall negotiate in good faith substitute obligations for such country during the Launch Period, which obligations take account of the product profile of the Combination Product. If there is a modification in Applicable Law or industry guidelines with respect to the compensation of, or activities performed by, pharmaceutical sales representatives, or if Detailing is prohibited at Customer facilities, then, to the extent such modification or prohibition would render the achievement of the Specific Targets commercially impracticable or unethical, then the Parties shall negotiate in good faith substitute obligations, which obligations take account of such modification or prohibition. If and for so long as the Base Price(s) with respect to one or more potential Customers does not permit the Selling Party to sell the Combination Product to such potential Customers and such inability would render the achievement of the Detailing obligations set forth in Section 6.2(b)(iii) commercially impracticable, then such obligations shall be reduced in proportion to the reduction in Detailing opportunities resulting from the inability to sell Combination Product to such Customer(s).

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

For clarification, the satisfaction of the obligations of subsections (i) to (iii) of this Section 6.2(b) does not necessarily, in and of itself, constitute satisfaction of Gilead’s obligations under Section 6.2(a).

(c) Performance; Subcontracting. Each Party shall comply, and shall cause its Affiliates and any of its permitted subcontractors to comply, with all Applicable Law and the requirements of all Approvals for the Combination Product in conducting their respective Commercialization Activities. Either Party may subcontract the performance of Commercialization Activities allocated to it hereunder, including to a contract sales organization or Distribution Subcontractor; provided, however, that (i) Gilead shall not use a contract sales organization in any of the Major Markets and (ii) the subcontracting Party shall oversee the performance by its subcontractors of such subcontracted Commercialization Activities in a manner that would be reasonably expected to result in their timely and successful completion and shall remain responsible for the performance of such Commercialization Activities in accordance with this Agreement.

6.3 Detailing Election.

(a) Election. With respect to any country in the Territory, the non-Selling Party shall have the non-exclusive right to elect to commence, at its expense, Detailing of the Combination Product in such country (provided, in the case of Tibotec, that it (or its Affiliate) markets the TMC278 Product in such country and, in the case of Gilead, that there is a wholly owned subsidiary of Gilead Parent located in such country, which subsidiary will perform the Detailing) (a “Detailing Election”). A Detailing Election shall be effective upon three (3) months’ prior written notice thereof to the Selling Party, which notice shall specify the date on which the non-Selling Party intends to commence such Detailing.

(b) Other Promotion by Tibotec. Tibotec may not market or promote (other than Detail) the Combination Product in any Gilead Country, but may, in connection with its activities relating to the TMC278 Product, respond to unsolicited questions that it receives with respect to the Combination Product. Gilead may elect to provide Tibotec with an approved slide deck or other background materials for use in responding to such questions. In the event that Gilead does elect to provide such materials, Tibotec shall respond to any unsolicited questions that it receives with respect to the Combination Product in a manner consistent with such materials (unless Tibotec believes in good faith that such materials are inconsistent with Applicable Law or its corporate policies).

6.4 Detailing of the TMC278 Product. Following the initial Approval of the TMC278 Product in the Field in any country in the Territory until the initial Approval of the Combination Product in the Field has been granted in such country, Gilead shall have the non-exclusive right, but not the obligation, to detail the TMC278 Product for use with Truvada in such country. In the event that Gilead desires to commence detailing of the TMC278 Product in a country, Gilead shall provide Tibotec written notice and the Parties shall, within thirty (30) days from the date of such written notice, agree on (a) the date on which Gilead may commence such detailing, and

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(b) the anticipated detail efforts and other related matters, such as field force training, promotional materials to be used by Gilead, if any, and key messages. In the course of such detailing Gilead shall use, and Tibotec shall supply (at Gilead’s cost), promotional materials for the TMC278 Product that have been approved or used by Tibotec or its Affiliates; provided, however, that in the event that, prior to the commencement of detailing of the TMC278 Product in a country, Gilead has complied with all agreed requirements for such detailing other than approval in accordance with Gilead’s policies and procedures of Tibotec’s promotional materials for the TMC278 Product for the applicable country, then Gilead may detail the TMC278 Product in such country using the Product Label and Insert for the TMC278 Product and no other promotional materials. Gilead shall not perform any detailing of TMC278 Product that is inconsistent with any of Tibotec’s promotional materials for the TMC278 Product, Applicable Law or the Product Label and Insert for the TMC278 Product. For the avoidance of doubt, (x) Gilead shall not receive any compensation for its efforts in detailing TMC278 Product, (y) Tibotec shall remain solely responsible for commercialization of the TMC278 Product, and (z) Gilead may not market or promote (other than Detail) the TMC278 Product.

6.5 Third Party Distributor Countries.

(a) In General. The Selling Party shall have the right, with respect to those countries in the Territory as to which it serves as the Selling Party, to engage a Third Party Distributor to Distribute Territory Combination Product. Any country in which the Selling Party has engaged a Third Party Distributor to Distribute the Territory Combination Product, for so long as a Third Party is so engaged, shall constitute a “Third Party Distributor Country”.

(b) Transfer Price. The price at which the Selling Party sells the Combination Product to a Third Party Distributor shall be determined in accordance with Section 7 and Annex R.

6.6 Distribution and Related Matters.

(a) Distribution Activities. With respect to each Permitted Launch Country, subject to the terms and conditions of this Agreement, the Parties hereby acknowledge and agree that, the Selling Party for such country (or its Third Party Distributor) shall have the right to Distribute the Territory Combination Product in such country. The Selling Party (or its Third Party Distributor) for such country shall have the sole responsibility and right to fill orders with respect to the Territory Combination Product in such country and shall have the sole responsibility and right to distribute (or cause its applicable Affiliate to distribute) the Territory Combination Product and to perform distribution activities with respect thereto, including inventory management and control, warehousing and storage, order filling, invoicing, collection of sales proceeds, determination and processing of charge-backs and rebates, preparation of sales records and reports, customer relations and services, and handling of returns (the “Distribution Activities”). The Selling Party shall not (i) grant rights to conduct any Distribution Activities with respect to the Territory Combination Product in the applicable country to any Person other than its Affiliates, Distribution Subcontractors or Third Party Distributors, (ii) sell or permit its

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Affiliates or Third Party Distributors to sell any Territory Combination Product in a country outside of the European Union if the Selling Party (or such Affiliate or Third Party Distributor) has reason to believe that such Territory Combination Product will be exported from such country to any country as to which such Party is not the Selling Party (including any country outside the Territory), and (iii) export or have exported (other than, in the case of Gilead, pursuant to any Tibotec Distributor Agreement), or permit its Third Party Distributor to export, any Territory Combination Product from any country outside of the European Union for purposes of Distribution (by such Party, its Affiliates or any other Person) in or to any country as to which it is not the Selling Party (including any country outside the Territory) without the written consent of the other Party, unless refusing to so export the Combination Product would violate Applicable Law. The Selling Party shall perform (or cause to be performed) the Distribution Activities in the Territory consistent with Applicable Law. The non-Selling Party with respect to a country in the Territory shall promptly forward (or cause its Affiliates to forward) to the Selling Party (or its designee) any order(s) for the purchase of the Combination Product for sale or use in such country that are received by the non-Selling Party or any of its Affiliates; provided that the non-Selling Party’s failure to forward any such order to the Selling Party (or its designee) shall not constitute a breach of this Agreement unless such failure constitutes willful misconduct.

(b) First Expiration, First Out. The Selling Party shall Distribute (and shall cause its Affiliates and Distribution Subcontractors to Distribute) all Territory Combination Product on a first expiration, first out (FEFO) basis.

6.7 Marketing Materials.

(a) Key Selling Messages. Gilead shall, and Tibotec may, develop and propose, and the Parties shall mutually agree upon, a set of core marketing messages with respect to the Combination Product. From time to time, either Party may propose updates to such core messages, which updates shall be mutually agreed by the Parties. Any such core messages approved by the Parties pursuant to this Section 6.7(a) and any updates thereto approved pursuant to this Section 6.7(a) shall be deemed the “Key Selling Messages.” If the Parties cannot reach agreement with respect to the Key Selling Messages or any updates thereto, the Parties shall (on a country-by-country basis if and to the extent appropriate) refer any disputed issues to the Executives for resolution pursuant to Section 2.4. If the Executives are unable to reach agreement with respect to a given core message, neither Party shall be obligated to use such message with respect to the Combination Product, but each Party shall be permitted to use such core message with respect to the Combination Product (and include such message in its Local Promotional Materials) if such message is consistent with both (i) the Product Label and Insert for the Combination Product approved by the applicable Regulatory Authority(ies) and (ii) Applicable Law.

(b) Local Promotional Materials. All advertising and promotional materials, if any, to be used in connection with the marketing and promotion, including Detailing, of the Territory Combination Product in a given country in the Territory (such advertising and

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

promotional materials for each such country, the “Local Promotional Materials”) shall be developed by the Party using such materials at its cost and expense and shall be (i) consistent with the Key Selling Messages (if any), (ii) consistent with the Product Label and Insert for the Combination Product approved by the applicable Regulatory Authority, (iii) consistent with Applicable Law, and (iv) in the case of Tibotec, consistent with the branding guidance provided by Gilead from time to time, with deviation solely to the extent required by Applicable Law. Any other deviation by Tibotec from such branding guidance shall require the written consent of Gilead. In the event that Gilead notifies Tibotec in writing of a modification to Gilead’s branding guidance or the Parties agree upon updates to the Key Selling Messages, each Party shall promptly review and update its Local Promotional Materials, if any, to conform such materials thereto. Except as otherwise provided in this Section 6.7, each Party shall use Local Promotional Materials (and only the Local Promotional Materials) for a given country (as developed in accordance with this Section 6.7), together with Product Label and Insert for the Combination Product approved by the applicable Regulatory Authority in such country, in marketing and promoting the Territory Combination Product in such country; provided, however, that subject to the foregoing, each Party (and its Affiliates) shall have a right to position the Territory Combination Product within its HIV product portfolio in its sole discretion.

(c) Regulatory Approval for Promotional Materials. For clarity, in any interactions with a Regulatory Authority with respect to the Local Promotional Materials, the allocation of the Parties’ rights and responsibilities shall be as set forth in Section 4.4.

(d) Compliance with Applicable Law. The Parties hereby agree and acknowledge that notwithstanding the provisions of this Section 6.7, neither Party shall be required to market the Combination Product utilizing Local Promotional Materials which such Party believes in good faith do not comply with Applicable Law.

6.8 Selection and Use of Trademarks. Gilead shall have the right to select the Combination Product Trademarks. Gilead shall not, and shall not permit its Affiliates to, select or use, as the Combination Product Trademark, any Trademark that is confusingly similar to, misleading or deceptive with respect to, or that dilutes any (or any part) of, the Product Trademarks for the TMC278 Product. Tibotec shall not, and shall not permit its Affiliates to, use, in connection with any Other TMC278 Product, any Trademark that is confusingly similar to, misleading or deceptive with respect to or that dilutes any (or any part) of the Combination Product Trademarks. Each Party shall refrain from, and shall cause its Affiliates and their respective sublicensees and subdistributors to refrain from, using, directly or indirectly, any Product Trademarks other than the Combination Product Trademarks, the Gilead Licensed Trademarks and Tibotec Licensed Trademarks in connection with the Exploitation of the Combination Product for sale or distribution in the Territory; provided, however, that, the foregoing shall not be construed to preclude either Party or its Affiliates from using any Trademark in connection with the Exploitation of the Combination Product for sale or distribution in the Territory to the extent that Applicable Law requires such Trademark to be so used.

6.9 Abandonment of Countries. Without limiting the obligations of the Selling Party pursuant to Sections 6.2 and 6.6 (and without limiting any rights or remedies the non-Selling Party may have in connection with a failure of the Selling Party to comply with such obligations), in the event the Selling Party determines, in its sole discretion, to abandon all Commercialization Activities (or not to file for Approval in the Field) for the Combination Product in a country in the Territory, the Selling Party shall promptly notify the other Party of such determination in writing, which notice shall include a reasonable description (including, supporting data, if applicable) of the justifications for such determination (each, a “Non-Commercialization Notice”). This right to abandon all Commercialization Activities (or not to file for Approval of the Combination Product in the Field) shall not apply to any Major Market. Thereafter, the non-Selling Party shall have the right, but not the obligation, to elect to engage in Commercialization Activities for the Combination Product (either itself or through a Third Party Distributor) in such country by delivery of written notice to the Selling Party within six (6) months after receipt of the applicable Non-Commercialization Notice; provided, however, that in the case of Tibotec as the non-Selling Party, Gilead shall have the right to consent to any such change in the designation of the Selling Party, such consent not to be unreasonably withheld (unless the country requested by Tibotec is a Designated Country, in which case, Gilead may withhold its consent in its sole discretion); provided, further, that if such Designated Country is in the European Union and the Combination Product has been launched in such country, then the Parties shall discuss in good faith the conditions under which Tibotec (or its Affiliates) might assume responsibility for Commercialization Activities in such country. In the event the non-Selling Party so elects to engage in Commercialization Activities for the Combination Product in such country, then for purposes of this Agreement (and any Ancillary Agreement), such Party shall thereafter be deemed to be the Selling Party with respect to such country, and in each case, the Parties shall work together in good faith to effectuate the transfer of responsibilities in connection with the foregoing to the other Party or a Third Party Distributor.

6.10 Patient Assistance Program; Product Donations.

(a) Patient Assistance. For each country in the Territory, the Selling Party shall have the right, but not the obligation, in accordance with its standard practice to respond to requests from individual patients who have or may obtain prescriptions for the Combination Product in such country but may be unable to afford it, and from health care providers on behalf of such patients, including establishing appropriate procedures and response times that shall apply in responding to such requests. The non-Selling Party with respect to any country in the Territory may not conduct any of the activities described in this Section 6.10(a), without the prior written consent of the Selling Party with respect to such country.

(b) Donations. Each Party shall have the right, but not the obligation, subject to the other Party’s consent, not to be unreasonably withheld, to donate Combination Product to any Third Party for use in any country in the Territory. Notwithstanding the foregoing, this Section 6.10(b) shall not apply to any Combination Product to be used in any Clinical Trial (which use is addressed in Section 8.3).

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(c) Price of Combination Product. In the event that either Party desires to use Territory Combination Product in connection with any activities permitted pursuant to Section 6.10(a) or (b), such Party may provide written notice to the other Party of its desire to use such Combination Product in connection with such activities, which notice shall specify the quantity of such Combination Product desired. If Gilead is the requesting Party, then notwithstanding anything to the contrary in this Agreement or the Ancillary Agreements, the compensation due to Tibotec (or its Affiliate) from Gilead (or its Affiliate) under the TMC278 Supply Agreement with respect to the quantity of the Supplied TMC278 corresponding to such quantity of Combination Product shall be adjusted so that it equals [*] and Gilead shall reimburse Tibotec for its portion of the Manufacturing Fees with respect to such quantity of Combination Product. If Tibotec is the requesting Party, Tibotec shall have the right to purchase such quantity of Combination Product for such purpose from Gilead (which quantity Gilead shall use reasonable efforts to supply to Tibotec as promptly as practical, taking into account Gilead’s Manufacturing capacity and schedule and the availability of TDF, FTC and the Supplied TMC278) at a price that [*] contained therein at [*], and Tibotec shall, in addition to paying its portion of the Manufacturing Fees with respect to such quantity of Combination Product, reimburse Gilead for Gilead’s portion of the Manufacturing Fees with respect to such quantity of Combination Product. Appropriate adjustments to the financial calculations hereunder and in any Ancillary Agreements shall be made to reflect the foregoing principles.

6.11 Commercialization Costs and Expenses. Except as otherwise expressly provided hereunder, each Party or its applicable Affiliate or Third Party Distributor shall bear all of its costs and expenses relating to its Commercialization Activities.

SECTION 7

PRICING

7.1 Pricing and Discounts in the Territory. The provisions set forth in this Section 7 shall apply to the pricing of Territory Combination Product sold by the Selling Party or any of its applicable Affiliates to any Third Party, including a Third Party Distributor. The Selling Party shall sell the Combination Product at prices that comply with this Section 7 and with the determinations of the Discount Committee (as defined below) made pursuant to the provisions of this Section 7 and Annex R. Given the close relationship between (a) the pricing of the Parties’ respective Stand-Alone Products, the TMC278 Product and Truvada, and (b) how the Parties anticipate the Territory Combination Product (TMC278 Product + Truvada) will ultimately be priced, the following pricing and reimbursement rules are necessary to facilitate the launch and pricing of the Territory Combination Product. In the absence of such rules, the Parties believe that it would be difficult to price the Territory Combination Product in a manner that protects the Parties’ respective financial interests in their Stand-Alone Products.

7.2 Discount Committee.

(a) Purpose. In order to ensure that only appropriate pricing information is communicated and that access to such information within each Party is limited, all

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

communications between the Parties to establish pricing for the Territory Combination Product shall be made solely through a special committee (the “Discount Committee” or “DC”), subject to Annex R. Except to the extent contained in the revenue reports contemplated in Annex Q, neither Party shall communicate to the other non-public pricing information concerning the Territory Combination Product or concerning any of its Single Agent Product(s) or Double Agent Product, as applicable, except through the DC and then only to the extent specifically authorized by this Agreement. No non-public information on their respective future pricing strategies shall be communicated between the Parties. The membership of the DC shall exclude employees who are responsible for determining pricing for a Party’s (or any of its Affiliates’) HIV antiviral products. The role of the DC shall be solely ministerial, i.e., to communicate necessary pricing information from one Party to the other and the DC members shall not make pricing decisions beyond the application of rules and calculations prescribed by this Agreement. Each Party is responsible for implementing internal procedures to restrict access to and use of the non-public pricing information received from the other Party so as to comply with this Agreement and Applicable Law.

(b) Members. Each Party shall appoint two (2) members of the Discount Committee. One (1) representative from each Party (the “Business Representative”) shall be an employee of such Party (or any of its Affiliates). The other representative from each Party (the “Attorney Representative”) shall be an attorney for such Party. Neither the Business Representative nor the Attorney Representative shall, at the time of his or her appointment, or at any time during his or her service on the DC, be involved, directly or indirectly, in the pricing of such Party’s (or any of its Affiliates’) antiviral products used to treat HIV infection, including any such products that are the subject of a collaboration with any Third Party (provided, that for purposes of this Section 7.2(b), duties solely with respect to accounts receivable analysis, bookkeeping and accounting shall not, without more, be deemed involvement in pricing). Such representatives shall have skills reasonably appropriate to their responsibilities and functions as members of the DC. Furthermore, each Party covenants that, for twelve (12) months immediately after an individual’s service on the DC (or for such shorter period as he or she is employed by such Party or its Affiliate), he or she will not be assigned to a function or position that involves, directly or indirectly, the pricing of such Party’s (or any of its Affiliates’) antiviral products used to treat HIV infection, including any such products that are the subject of a collaboration with any Third Party. Each Party shall have the right to approve the other Party’s proposed Business Representative and Attorney Representative on the DC (or any replacement therefor), which approval shall not be unreasonably withheld. Subject to the preceding sentence, each Party shall have the right to replace its Business Representative or Attorney Representative from time to time during the term of this Agreement, provided that the composition of the DC as so changed meets the requirements set forth above in this Section 7.2(b).

(c) Firewall Policies. Reasonably in advance of Launch of the Combination Product in the first country in the Territory, Gilead shall develop and propose to Tibotec for approval, not to be unreasonably withheld, one or more policies designed to prevent disclosure by Gilead to Bristol-Myers Squibb Company or any of its affiliates (“BMS”) or Merck & Co.,

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Inc. or any of its affiliates (“Merck”) of non-public pricing information provided to Gilead by Tibotec, and to prevent disclosure by Gilead to Tibotec of any non-public pricing information received by Gilead from BMS or Merck. Gilead may modify such policies from time to time, provided that such modifications are approved by Tibotec, such approval not to be unreasonably withheld. Gilead shall comply with any of its policies adopted pursuant to this Section 7.2(c), as modified from time to time in accordance with this Section 7.2(c) (each such policy, a “Firewall Policy”).

(d) DC Member Oversight. Each Party shall be responsible for the performance of its representatives on the DC and their compliance with the terms of this Section 7 and Annex R. Any issue regarding the functioning of the DC shall be reviewed jointly by the Parties’ respective Attorney Representatives. Each Party shall bear its own costs and expenses related to the DC, including all costs and expenses relating to the meetings of the DC, the participation of the Parties’ representatives in such meetings, communications with the other Party in connection with such meetings or matters within the authority of the DC, and travel to and from such meetings.

(e) Meetings. The Discount Committee shall meet at least each Calendar Quarter (which meeting may be conducted by telephone or videoconference equipment, so long as each attendee is able to hear the others), and as otherwise required from time to time, to determine such matters as are within the jurisdiction of the Pricing Committee as set forth in this Section 7.2.

(f) Authority. The Discount Committee shall perform only such functions as are assigned to the Discount Committee hereunder. The Discount Committee shall apply Annex R to make such calculations and determinations as are specified in Annex R.

(g) Information Exchange. The representatives of each Party on the Discount Committee shall, in connection with the calculation of any Base Price with respect to a Customer, provide the Discount Committee with (i) its Desired Component Price and (ii) such other limited pricing information, if any, with respect to such Customer as the Attorney Representatives shall agree is necessary and appropriate.

(h) Disputes. In the event that interpretation or application of this Section 7 or Annex R is necessary in order to implement the provisions of this Section 7 or Annex R, the Business Representatives shall discuss the matter with the Attorney Representatives and attempt to resolve the matter by consensus. In the event that the Attorney Representatives disagree regarding any such interpretation or application, either Attorney Representative may refer the dispute to the Executives for resolution pursuant to Section 2.4.

(i) Retention of Counsel. The Discount Committee may determine, by consensus and in its sole discretion, to retain independent legal counsel, in which case the costs and expenses of such counsel shall be shared by the Parties in accordance with their Actual Percentages.

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(j) Launch Coordination Committee. In order to obtain necessary pricing approval for the Combination Product as soon as possible after receiving marketing approval to sell the TMC278 Product and submitting applications for marketing approval for the Combination Product in Major Market countries, the Parties agree that reasonably in advance of Launch in any such country that is a Permitted Launch Country, the Parties shall establish an Ad Hoc Operating Committee (each a “Launch Coordination Committee”) solely for the purpose of establishing a schedule for and coordinating logistics regarding (i) preparing and filing dossiers for price approvals for the Combination Product in such country, if applicable, (ii) establishing the Minimum Target Price, if applicable, and (iii) establishing the initial Base Price for significant potential Customers in such country. Such committee shall be comprised of representatives from each Party and shall make decisions by consensus, consent of the non-Selling Party not to be unreasonably withheld. Each Party shall inform the other Party in writing of its proposed Launch Coordination Committee members, which members shall be subject to the other Party’s consent, not to be unreasonably withheld. Such committee may, in cooperation with the Discount Committee, revise any of the applicable time periods set forth in this Section 7 or Annex R in the interest of facilitating an effective launch of the Combination Product in such country, including time periods for (A) providing Territory Pricing Information, including DCPs, to the Discount Committee or (B) responding to any Customer-requested discounts communicated through the Discount Committee with respect to the Combination Product, but shall not have authority to alter or deviate from any other provisions or rules of Section 7 or Annex R without consent of each Party, which it may grant or withhold in its sole discretion. For clarity, the Launch Coordination Committee is not intended as a substitute for the Discount Committee, shall not perform any of the functions of the Discount Committee and a Party’s members of the Launch Coordination Committee shall not discuss with, or otherwise disclose to, the other Party’s members any pricing information relating to such Party’s Stand-Alone Product or the pricing strategy for the Combination Product. At the request of either Party, its legal counsel, or at the request of both Parties, the independent legal counsel described in Section 7.2(i), shall be permitted to attend any or all meetings of a Launch Coordination Committee, for the purpose of monitoring and ensuring compliance with the rules and requirements of this Section 7.2(j) and Applicable Law.

7.3 Country-Level Pricing.

(a) In General. With respect to any given country of the Territory in which the Combination Product is sold, the Selling Party shall offer to sell the Combination Product at the Country Price for such country unless otherwise specifically provided in this Section 7. The “Country Price” in non-Price Approval Countries shall be determined in accordance with Section 7.3(b) and in Price Approval Countries shall be set in accordance with Section 7.3(c).

(b) Non-Price Approval Countries. The Country Price for the Combination Product in any non-Price Approval Country shall be 1+1 EXP [*] such Stand-Alone Product occurred, or as promptly as practicable thereafter (and shall not be in breach of Section 7.3(a) provided that it implements such change as of such date).

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(i) Minimum Target Price. The minimum acceptable Approved Price (the “Minimum Target Price”) to be obtained in connection with any negotiations by the Selling Party (or its applicable Affiliate) with the applicable pricing authority for the purpose of obtaining any initial Approved Price for the Combination Product in any Price Approval Country shall equal the then current 1+1 Approved Price in such country or such other price as the Parties may agree in writing. Prior to the commencement of such negotiations each Party shall provide to the other the applicable then-current Approved Price for its Stand-Alone Product. The non-Selling Party shall notify the Selling Party if it desires to include in the calculation of the Minimum Target Price a lower price than [*] and the Minimum Target Price shall automatically be adjusted to reflect such lower price. The Selling Party shall use Commercially Reasonable Efforts to obtain and maintain an Approved Price for the Combination Product that is equal to the then-current Minimum Target Price in such country. If the initial Minimum Target Price is not obtained, the Selling Party may elect not to launch the Combination Product in the applicable country and shall not launch without the consent of the other Party. Each Party shall provide the other Party through the DC notice (in advance, if possible) of any [*] and the Minimum Target Price shall automatically be adjusted to reflect such change. At Launch and thereafter, unless modified as below, the Country Price shall be the [*].

(ii) Ongoing Selling Party Price Approval Obligations for Price Approval Countries. Except as otherwise agreed by the Parties, with respect to any Price Approval Country, the Selling Party shall be responsible for managing the negotiation with the applicable authority(ies) in each such country in the Territory to obtain and maintain pricing approval and shall use Commercially Reasonable Efforts to obtain and maintain pricing approval; provided, however, that for purposes of clarity, Commercially Reasonable Efforts shall not require the Selling Party to consent to a price for the Combination Product that is lower than the Minimum Target Price for the applicable country. In conducting such negotiations, the Selling Party shall cooperate with the other Party and act in accordance with this Section 7.3(c)(ii). Upon the request of the non-Selling Party, Selling Party shall make available to the other Party a copy of the initial submission for obtaining pricing approval for the Combination Product in each country in the Territory for review in advance of its filing. Upon request of the non-Selling Party, the Selling Party shall furnish the other Party with a copy of all materials received from such authorities, together with all reports and other communications submitted by the Selling Party to such authorities, in each case solely to the extent relating to the Combination Product.

(iii) Seeking Modified Pricing Approvals; Proposed Governmental Reductions. In the event that an initial Approved Price is obtained in a Price Approval Country, [*]. If a pricing authority in a given country proposes to reduce an Approved Price for the Combination Product, the Selling Party shall use Commercially Reasonable Efforts to maintain such Approved Price at a price equal to the then-current Minimum Target Price with respect to

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

such Approved Price. Any voluntary reduction of the Approved Price to a price less than the then-current Minimum Target Price shall first be approved by the non-Selling Party.

(iv) Mandatory Price Reductions. Notwithstanding any other provision of this Agreement, in the event that, following the Launch of the Combination Product in a given Price Approval Country, [*].

(d) Sub-National Pricing. If any sub-national pricing authority (such as a Canadian province) in a country in the Territory requires pricing approval that is distinct from national pricing approval in such country, or in the case in which there is no national pricing approval, negotiations with such sub-national pricing authority with respect to such sub-national pricing approval shall be subject to this Section 7 as if such pricing approval were an Approved Price and as if such sub-national pricing authority were a national pricing authority.

(e) In-Market Pricing in Third Party Distributor Countries. The Parties shall not place any restrictions on the price at which a Third Party Distributor may sell Territory Combination Product in its applicable Third Party Distributor Country.

7.4 Customer-Level Pricing and Discounts. This Section 7.4 shall cover discounts to the Country Price for any proposed sale of the Territory Combination Product to any Customer. On a Customer by Customer basis, the Selling Party shall sell the Territory Combination Product at the Base Price or the Discounted Price, rather than the Country Price, according to the terms of this Section.

(a) Base Price Setting.

(i) In General. On a Calendar Quarter basis and [*], each Party shall provide to the Discount Committee, for each Customer, its Desired Component Price. If a Party’s Desired Component Price is not so provided for a given Customer, its DCP for such Customer shall equal [*]. Each Party may set its “Desired Component Price” with respect to a Customer at any price in its sole discretion, subject to the remainder of this clause (a). For each Calendar Quarter [*] (such price, as adjusted pursuant to this Agreement, the “Base Price”). In the event that any Customer requests a price that is less than the Base Price (“Discounted Price”), Annex R shall apply. The Discount Committee shall be responsible, on an ongoing basis, for calculating and providing to the Selling Party the Base Price, as adjusted if applicable pursuant to Annex R. In no event shall the setting of the Base Price or application of Annex R result in a price that may be deemed at that time to be the “new best price” under the Medicaid “best price” calculation. The Selling Party shall not sell any Territory Combination Product to any Customer at a price, or agree to a reimbursement price for the Combination Product in connection with any formulary listing of a Customer, that is different than the Base Price in effect at the date on which the applicable contract with such Customer is executed, as adjusted pursuant to Annex R, if applicable. Notwithstanding the foregoing, if the Selling Party would be required to [*], the matter shall be considered a Discount Deadlock and referred to the Discount Committee for resolution pursuant to Annex R; pending resolution by the Discount Committee,

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

the Base Price with respect to such Customer shall be [*]. The term for any agreement to sell Territory Combination Product to a Customer shall not exceed [*] or, if applicable, such longer period as is agreed pursuant to Section 2B of Annex R.

(ii) Exceptions. Notwithstanding Section 7.4(a)(i), the following shall apply:

(A) Third Party Distributors.

(1) Initial Transfer Price. For Combination Product sold by the Selling Party to a Third Party Distributor, the initial transfer price for the Combination Product to the Third Party Distributor shall be [*].

(2) [*].

(3) [*].

(4) [*].

(5) Pricing Discretion. For the avoidance of doubt, nothing in this clause (A) shall prevent the Third Party Distributor from being free unilaterally to set its selling price for the Combination Product to any customer.

(B) Wholesalers. For Combination Product sold by the Selling Party to a wholesaler, the initial price at which the Selling Party sells the Combination Product to such wholesaler shall be [*], as determined pursuant to Section 7.4(a).

(1) “Medicaid Sales” shall mean sales of Territory Combination Product purchased directly by Medicaid at a discount to the EXP, or sold by the Selling Party and subject to a Downstream Discount Trigger due to a subsequent sale covered by Medicaid.

(2) “Medicaid DCP” shall mean, without limitation of Section 7.4(a)(ii)(B), with respect to a given Calendar Quarter (x) [*]. Each Calendar Quarter, Tibotec shall notify Gilead of its DCP for each Customer that is a Medicaid entity as described in Section 7.4(a).

(3) Price of the Territory Combination Product. The Parties acknowledge that Medicaid will determine the price that it will pay for the Combination Product based on the WAC of the Combination Product. The Selling Party shall set the WAC for the Combination Product in the United States at [*]. The Parties acknowledge that price increases for the Territory Combination Product for Medicaid Sales will be subject to

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Medicaid mandatory discounts so as to limit the effective price increase to Medicaid to increases in the Consumer Price Index – Urban (CPIU).

(4) Rebates to Medicaid Customers. Gilead shall provide to Customers that are Medicaid entities any required Medicaid discounts for the Combination Product and shall [*].

(5) [*].

(6) Revenue Share. [*] shall be used as such Party’s DCP for purposes of determining each Party’s share of revenues from Medicaid Sales to that Customer.

(7) Medicaid Changes. The foregoing provisions on sales of the Territory Combination Product into the Medicaid program are based on Medicaid laws, regulations and practices on the Effective Date. In the event of any changes to such Medicaid laws, regulations and practices, the Parties agree to negotiate in good faith replacement provisions for the allocation of the revenues from Medicaid Sales between the Parties that preserve, as nearly as possible, consistent with Applicable Law, the economic benefit to each Party as those set forth herein.

(D) Tenders. In the case of Combination Product to be sold to a governmental purchaser pursuant to a tender, in advance of the Selling Party’s participation in such tender, the Parties, through their members on the Discount Committee, shall negotiate in good faith to agree in writing on rules and procedures applicable to such tender that are consistent with Applicable Law (including without limitation all national and local statutes and other laws governing tenders in the applicable jurisdiction) and which permit the Parties legally to communicate their respective DCPs within the context of such tender (to the extent the Parties have not agreed on a method of participating in the tender that does not require such communication). In order to determine which procedures are consistent with Applicable Law, the Selling Party may discuss with the governmental purchaser in advance of the tender the Parties’ proposed methods of communicating their respective DCPs to each other or to the governmental purchaser, as applicable. To the extent possible under Applicable Law, the Discount Committee shall attempt in good faith to agree on rules and procedures applicable to such tender that permit the Parties to follow the procedures for determining a Base Price set forth in Section 7.4(a)(i). In the event that the Discount Committee is unable to agree on rules and procedures applicable to such tender, the Selling Party may offer to sell the Combination Product in such tender, but the non-Selling Party’s DCP for purposes of such tender shall be [*]. All the provisions of this Section 7.4(a)(ii)(D) shall likewise apply to any sale of Combination Product to any non-governmental purchaser pursuant to a tender if either Party reasonably believes participation in such tender on the basis of the other rules, procedures and provisions of Section 7 would violate Applicable Law.

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(b) Modification of Desired Component Prices. On a Calendar Quarter basis or at such interval as the Parties may otherwise agree, for each country, as provided in Section 7.4(a), each Party shall update its Desired Component Prices, including to take account of changes to the applicable [*]. Subject to the limitations in Section 7.4(a), a Party may revise its Desired Component Price with respect to any Customer. In either case, unless otherwise agreed by the Parties in writing, the modification of a Party’s Desired Component Price with respect to a Customer shall become effective on the [*] with respect to such Customer solely with respect to future negotiations and contracts with such Customer and shall not apply to the price that is in effect under any existing contract with such Customer.

(c) Pricing Information. All information provided to the Discount Committee that is not publicly available (“Territory Pricing Information”) shall be considered Confidential Information of the disclosing Party and shall be used solely for the purpose of making the applicable calculation under Annex R, setting any applicable Base Price and making any other calculation required under this Agreement or any Ancillary Agreement and for no other purpose. Except as expressly permitted by this Section 7 or Annex R, each Party shall cause its representatives on the Discount Committee not to disclose any Territory Pricing Information of the other Party except to the Independent Accounting Expert engaged pursuant to Section 12.2, to counsel, or to other employees of the receiving Party or its Affiliates who require access to the Territory Pricing Information of the other Party in order to perform their role or function in furthering the purposes of this Agreement (“Necessary Personnel”). All Territory Pricing Information shall be segregated in locked or password protected files maintained by the Discount Committee, which files shall not be accessible by Persons other than the members of the Discount Committee and the receiving Party’s Necessary Personnel (which access of Necessary Personnel shall be solely to the extent necessary for the performance of such Necessary Personnel’s role and function in furthering the purposes of this Agreement), and each Party shall cause its representatives on the Discount Committee and any Necessary Personnel not to reference or use, directly or indirectly, any Territory Pricing Information of the other Party in pricing its or any of its Affiliates’ other products, including any such products that are the subject of collaborations with Third Parties. For the avoidance of doubt, setting the pricing of each Party’s respective Stand-Alone Product, or other combination product incorporating such Stand-Alone Product, is not a purpose of this Agreement, and no Territory Pricing Information shall be disclosed for such purpose.

(d) Review of Rules. On an annual basis, or as requested by either Attorney Representative in the event that such representative believes that this Section 7 or Annex R do not cover a scenario with respect to Territory Combination Product that needs to be addressed, the Parties shall review this Section 7 and Annex R (in each case, as most recently amended pursuant to this Section 7.4(d), if applicable) in light of the then-prevailing market conditions. If (and only to the extent that) the Parties reflect any changes to this Section 7 or Annex R, as the case may be, in a formal written amendment to this Agreement, which amendment is signed by both Parties, will such changes be effective and binding on either Party, whereupon this Section 7 or Annex R, as applicable, as so changed shall be deemed to be Section 7 or Annex R for all

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

purposes hereunder. For the avoidance of doubt, the Parties’ action or inaction under this Section 7.4(d) shall not be subject to arbitration.

(e) Government Purchasers. In the event that, following Launch of the Combination Product in a given country, a governmental purchaser [*].

(f) Shared Revenue Reduction Events. In the event and to the extent that (i) any Mandatory Reduction occurs as contemplated by Section 7.3(c)(iv), or (ii) a government purchaser imposes a purchase price for the Territory Combination Product that is lower than the Base Price with respect to such purchaser pursuant to Section 7.4(e) (each, a “Revenue Reduction Event”), then each Party’s DCP for Territory Combination Product sales affected by the Revenue Reduction Event shall be [*].

(g) Certain Shared Charges. In the event that Applicable Law, the Patented Medicine Prices Review Board (“PMPRB”), with respect to Canada, or any other similar government authority in any country in the Territory, [*] The non-Selling Party shall issue a credit note to the Selling Party as is required to achieve the allocation described in this Section 7.4(g).

7.5 Pricing and Other Contract Negotiations. As between the Parties (and their respective Affiliates), the Selling Party (and its Affiliates) shall have primary responsibility for conducting pricing and discounting negotiations (and all other contracting matters) with respect to the Combination Product with Customers in the applicable country in the Territory in accordance with this Section 7 and Annex R; provided, however, that except as otherwise agreed by the Parties in writing, subject to Section 7.3(e), the Third Party Distributor in any Third Party Distributor Country shall have all rights and responsibilities with respect to the foregoing activities. The non-Selling Party may discuss with a Customer the amount that such Party anticipates that the Selling Party will charge for the non-Selling Party’s component incorporated within the Combination Product.

7.6 Pricing of Single Agent Products/Double Agent Product. Gilead and Tibotec shall each retain sole discretion with respect to price-setting and discounts for its respective Single Agent Products and Double Agent Product. Notwithstanding the foregoing, each Party covenants that it shall act in good faith in setting the price and discounts for its respective Single Agent Products and Double Agent Product in the Territory and shall not directly or indirectly manipulate pricing or discounting arrangements of its own Single Agent Products or Double Agent Product in the Territory solely or primarily for the purpose of increasing such Party’s portion of the revenue from the Territory Combination Product.

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(a) The Parties acknowledge and agree that, subject to Section 8.3, the Parties’ rights and obligations with respect to the supplies of the TMC278 (in API or other form) for use in the Combination Product for commercial sale in the Territory and Clinical Trial use consistent with this Agreement (other than the Combination Product Development Activities, unless TMC278 (in API or other form) initially provided for Combination Product Development Activities is to be used for commercial sale in the Territory as set forth in Section 8.1(b)) shall be as set forth in a TMC278 (in API or other form) supply agreement (the “TMC278 Supply Agreement”) to be negotiated in good faith and entered into by the Parties (or their applicable Affiliates). The Parties shall attempt in good faith to execute (or cause to be executed) such agreement within one hundred twenty (120) days after the Effective Date.

(b) Without limitation of either Party’s (or its Affiliates’) rights and obligations under the TMC278 Supply Agreement, Tibotec shall, at its sole cost and expense, supply quantities of TMC278, in such form as supplied under the MTA, to Gilead as promptly as practicable following a reasonable request from Gilead for such TMC278 for use in the Combination Product Development Activities. Gilead shall promptly notify Tibotec in the event that any quantity of TMC278 (in API or other form) supplied under the MTA for use in Combination Product Development Activities is incorporated into Territory Combination Product intended for commercial sale in the Territory; provided that no commercial sales of Combination Product shall be made until the TMC278 Supply Agreement is executed. Promptly following receipt of any such notice, Tibotec shall invoice Gilead at the Pre-Conversion Supply Price in accordance with the terms of the TMC278 Supply Agreement for the quantity of TMC278 (in API or other form) identified in Gilead’s notice and such TMC278 (in API or other form) shall be treated for all purposes (including the invoicing and payment of the Post-Conversion Supply Price) hereunder and under any Ancillary Agreement as though it were supplied by Tibotec under the TMC278 Supply Agreement.

8.2 Combination Product Supply to Tibotec. The Parties acknowledge and agree that the supply of Combination Product to Tibotec for Distribution in the Tibotec Countries (if any) shall be governed by the applicable Tibotec Distributor Agreement with respect to such country.

8.3 Supplies of Combination Product for use in Clinical Trials. In the event that the Party sponsoring or conducting a Clinical Trial (other than the bioequivalence studies covered under Section 8.1(b)) desires to use Combination Product Manufactured for sale and distribution hereunder (and does not desire to purchase such Combination Product from a Third Party), such Party may provide written notice to the other Party of its desire to use such Combination Product in such Clinical Trial, which notice shall specify the quantity of such Combination Product desired. If Gilead is the requesting Party, Gilead shall have the right to use such Combination Product and, notwithstanding anything to the contrary in this Agreement or the Ancillary Agreements, (a) the due date for the Pre-Conversion Invoice (or portion thereof) with respect to the quantity of the Supplied TMC278 corresponding to such quantity of Combination Product shall be the last day of the calendar month following the month in which such written notice was provided by Gilead hereunder with respect to such quantity of the Supplied TMC278, (b) no

Additional Supply Price shall be due to Tibotec with respect to such quantity of Supplied TMC278 and (c) Gilead shall reimburse Tibotec for its portion of the Manufacturing Fees with respect to such quantity of Combination Product. If Tibotec is the requesting Party, Tibotec shall have the right to purchase such quantity of Combination Product for such purpose from Gilead (which quantity Gilead shall use reasonable efforts to supply to Tibotec as promptly as practical, taking into account Gilead’s Manufacturing capacity and schedule and the availability of TDF, FTC and the Supplied TMC278) at a price that compensates Gilead for the TDF and FTC contained therein at the TDF Replacement Cost and FTC Replacement Cost, respectively, plus [*], and the compensation due to Tibotec (or its Affiliate) from Gilead (or its Affiliate) under the TMC278 Supply Agreement with respect to the quantity of the Supplied TMC278 corresponding to such quantity of Combination Product shall be adjusted so that such Supplied TMC278 is provided free-of-charge (or, as elected by Tibotec, the Tibotec-entity purchasing such Combination Product shall reimburse Gilead for any amount due to Tibotec (or its Affiliate) pursuant to the TMC278 Supply Agreement for such quantity of Supplied TMC278), and Tibotec shall, in addition to paying its portion of the Manufacturing Fees with respect to such quantity of Combination Product, reimburse Gilead for Gilead’s portion of the Manufacturing Fees with respect to such quantity of Combination Product.

8.4 Additional Requirements. In the event that Applicable Law or a Regulatory Authority in the Territory imposes, with respect to the Manufacture of Combination Product (or TDF, FTC or the Supplied TMC278 contained therein) for sale or distribution in one or more countries in the Territory, a requirement that is not imposed by any of the EMEA, the European Commission and the FDA with respect to the Manufacture of the Combination Product (or such component) for sale or distribution in the European Union or United States, as applicable (an “Additional Requirement”), the Selling Party for such country that requires the Additional Requirement shall notify the non-Selling Party of such Additional Requirement. The Parties shall consider the relative costs and benefits of complying with such Additional Requirement and discuss whether, how and when to implement such Additional Requirement in order to obtain or maintain Approvals for the Combination Product in the Field in the applicable country(ies). In the event that the Parties determine to implement such Additional Requirement, the Parties shall establish an implementation plan for such Additional Requirement. Either Party’s obligation hereunder or under any Ancillary Agreement to comply with any Additional Requirement, and the allocation between the Parties of costs to be incurred pursuant to such obligations, shall be solely as agreed under such plan. In the event the Selling Party with respect to a country fails to notify the other Party of any Additional Requirement with respect to such country pursuant to this Section 8.4, the non-Selling Party shall not be liable hereunder or under any Ancillary Agreement for any failure to comply with such Additional Requirement and such a failure shall not constitute a default hereunder or under any Ancillary Agreement.

Any amounts due hereunder shall be paid in the currency in which such amounts are invoiced.

(b) Notwithstanding paragraph (a) above, payments pursuant to Section 10.4(a) or 10.4(b) shall be made in the same currency as the [*]; provided that (i) such currency is a Hedge-able Currency and (ii) the aggregate of such payments in all countries in such currency in the applicable Calendar Year (with respect to a given currency, “[*]”) is forecasted (in the first forecast for a Calendar Year that is provided by Tibotec as described below) to be [*] or more. For any payments pursuant to Section 10.4(a) or 10.4(b) that do not meet the criteria set forth in the foregoing proviso (i.e., do not meet the threshold or are [*] in a non-Hedge-able Currency), such payment shall be made in U.S. Dollars, converted into U.S. Dollars using the standard methodology described in Section 10.9(b), but based on exchange rates reported using the Bloomberg service described in Section 10.9(a). For clarity, once determined pursuant to this clause (b) for a given country, the applicable currency for payments pursuant to Sections 10.4(a) and 10.4(b) with respect to such country for a given Calendar Year shall not be altered, even if such forecast of the [*] for such currency proves to be inaccurate. On or before the 31st of October of each Calendar Year, Tibotec shall provide to Gilead a good faith forecast of the [*] for the upcoming Calendar Year for each Hedge-able Currency, which forecast shall be broken down by Calendar Quarter and stated in the applicable Hedge-able Currency, and the applicable payment currency for purposes of Sections 10.4(a) and 10.4(b) for each country that has such Hedge-able Currency shall be determined based on such forecast. Tibotec shall update such forecast on or before June 30th of each Calendar Year as set forth in Annex Q. “Hedge-able Currency” means any of the following: [*].

10.9 Currency.

(a) At the end of each month, including for the purpose of all end-of-month calculations, Net Sales and Net Selling Prices for the Combination Product shall be converted into U.S. Dollars using the actual average daily exchange rate for such month for converting the applicable currency into U.S. Dollars, as such rate is reported in Bloomberg Professional (R) service application.

(b) For all purposes (hereunder and under any Ancillary Agreement) other than making the calculations described in Section 10.9(a), the Party responsible for making any currency conversions shall, in a manner consistent with its then-current standard worldwide currency conversion methodology, convert the applicable amounts incurred or sold, as the case may be, into the applicable currency.

(c) Except as otherwise provided in this Agreement, any invoices (or credit notes) and payments provided or made hereunder that constitute adjustments to any invoices or payments made pursuant to any Ancillary Agreement shall be provided or made, as applicable, in the currency in which the corresponding invoices or payments under such Ancillary Agreement are required to be provided or made pursuant to such Ancillary Agreement.

(d) Notwithstanding this Section 10.9 or any Ancillary Agreement, the Parties may, by mutual written agreement, modify (i) the applicable currency for invoicing and payments provided or made hereunder or under any Ancillary Agreement, or (ii) the manner in which any currency conversion is to be made hereunder or under any Ancillary Agreement.

10.10 Interest. Interest on any payments due and owing pursuant to this Agreement that are not timely made shall accrue from the date such payments are due at the lesser of (a) an annual rate equal to the sum of (i) the prime rate of interest in force on the date the payment is due as published in The Wall Street Journal (Eastern United States Edition) (in the case of payments to be made in United States dollars) or the European Central Bank main refinancing rate (as published in the Central Bank and Financial Services Authority for Ireland website www.centralbank.ie) (in the case of payments to be made in any currency other than United States dollars) and (ii) [*] and (b) the maximum rate of interest permissible under Applicable Law. For clarity, interest on any disputed payments or amounts due under this Agreement, including amounts determined to be due pursuant to an audit or adjustment as set forth in Section 12, shall be calculated as specified in this Section 10.10, provided that interest shall accrue on such payments or amounts from the date such payment or amount was originally due hereunder.

Each Party shall pay to the proper taxing authority any and all withholding taxes or

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

similar charges imposed by any governmental unit that are required to be withheld from any amounts due to the other Party pursuant to this Section 10, and proof of payment of such taxes or charges shall be secured and sent to such other Party as evidence of such payment. All amounts withheld and paid by a Party pursuant to the immediately preceding sentence with respect to taxes for which the other Party is responsible pursuant to the first sentence of this Section 10.11 shall be paid for the account of such other Party and deducted from the amounts due from the paying Party to such other Party pursuant to this Section 10.

10.12 Royalty Payments to Third Parties.

(a) If a Patent of any Third Party is or would be infringed or any such Person’s trade secrets are or would be misappropriated solely as a direct result of (i) TDF, FTC or both TDF and FTC being incorporated into the Combination Product (where, for purposes of clause (i) of this Section 10.12(a) and Section 10.12(b), “incorporation” shall be construed to mean the presence of an API in the Combination Product, not the process whereby such API is included in the Combination Product or the formulation of the Combination Product and “incorporated” shall be construed in a corresponding manner), or (ii) the process whereby TDF or FTC is included in the Combination Product, or (iii) the formulation of the Combination Product, then Gilead shall be solely responsible for any royalty, license fee or other payment obligation to such Person in connection with any such infringement or misappropriation in connection with the Territory Combination Product (or the TDF or FTC included therein) or any other activities conducted hereunder or under any Ancillary Agreement.

(b) If a Patent of any Third Party is or would be infringed or any such Person’s trade secrets are or would be misappropriated solely as a direct result of the Supplied TMC278 being incorporated in the Territory Combination Product, then Tibotec shall be solely responsible for any royalty, license fee or other payment obligation to such Person in connection with any such infringement or misappropriation in connection with the Territory Combination Product (or the Supplied TMC278 included therein).

(c) In the event that either Party (a “License Requesting Party”) believes in good faith that the Manufacture and supply of the Territory Combination Product (other than the Manufacture and supply of TDF, FTC or the Supplied TMC278) or the performance of either Party’s activities with respect to the Territory Combination Product hereunder requires a license to quiet infringement of any Patent or other intellectual property of any Third Party (other than a Patent for which one of the Parties has responsibility for royalties, fees and other payment obligations pursuant to Section 10.12(a) or Section 10.12(b), and other than a Patent or other intellectual property for which such Party already has a license) (each, an “Additional Required License”), such Party shall notify (prior to contacting the Third Party, if practicable, and in any event prior to entering into any agreement with respect to such Additional Required License) the other Party in writing and the Parties shall consider in good faith whether one or both of such Parties shall enter into licensing negotiations with respect to such Patent or other intellectual property and if so, shall coordinate in good faith with respect to such matter to the extent mutually agreed. In connection with one or both of the Parties entering into any Additional

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Required License, the Parties shall negotiate in good faith to determine appropriate terms of such license, including the term, the scope and the rights to the licensed intellectual property. Any royalties, fees or other similar payment obligations that may arise under an Additional Required License, to the extent relating to the Combination Product sold hereunder, shall be shared by the Parties [*]. If the Parties cannot agree on whether to obtain an Additional Required License or the appropriate terms therefor, Gilead shall have the right to obtain the Additional Required License and the immediately preceding sentence shall apply except to the extent that Tibotec establishes that such royalties, fees or other similar payment obligations are unreasonable under the circumstances.

(d) Nothing herein shall be construed to prevent either Party or any of its Affiliates from entering into any in-license agreement with respect to the Combination Product or otherwise; provided, however, that in the event that a Party desires to enter into such an in-license agreement with respect to the Combination Product, such Party shall comply with Section 10.12(c), provided, further however, that if the license in question is not an Additional Required License, the other Party shall have no obligation to bear any cost thereof.

(b) Decision to Recall or Withdraw. Within a period of time reasonable under the circumstances after the date of a notice given pursuant to the first sentence of Section 13.2(a) that relates to, or otherwise has implications for, the Exploitation of the Territory Combination Product in any country(ies) in the Territory, for each country in the Territory, the Selling Party with respect thereto shall recall or withdraw the Territory Combination Product in such country if the Recall/Withdrawal Criteria (described below) are met with respect to such country. In such a case, the Selling Party shall determine in its reasonable judgment (i) the extent to which to conduct such recall or withdrawal (where such determination shall be made by the Selling Party, in its reasonable judgment, based on the circumstances (e.g., a discrete Manufacturing non-conformity would justify a recall with respect to the applicable quantities of Combination Product, but not a market withdrawal of the Combination Product from such country)), (ii) the breadth, extent and level of customer to which any such recall or withdrawal shall reach, (iii) the strategies and notifications to be used, and (iv) other related matters with respect to the conduct of such recall or withdrawal. The “Recall/Withdrawal Criteria” shall be deemed to have been met in any country in the Territory if (A) the recall or withdrawal is mandated by any Regulatory Authority, (B) the Selling Party reasonably determines to recall or withdraw the Territory Combination Product, or the non-Selling Party reasonably requests such recall or withdrawal in writing, and such determination by the Selling Party, or such request by the non-Selling Party, is made: (v) for failure of the Territory Combination Product to meet the specifications therefor, (w) with a reasonable basis to conclude that material harm to patients may occur in the absence of such recall or withdrawal, (x) in the event the Manufacture of the Territory Combination Product sold in such country does not comply with Applicable Law, (y) on account of safety issues with respect to the Territory Combination Product or either Party’s Single Agent Product(s) or Double Agent Product, as the case may be, including, in the event of a withdrawal of any Single Agent Product(s) or Double Agent Product, as the case may be, from markets in the European Union or the United States for safety concerns, or (z) on account of a Regulatory Authority mandating a withdrawal of either Party’s Single Agent Product(s) or Double Agent Product, as the case may be, from markets in the European Union or the United States or (C) the Parties mutually agree in writing to recall or withdraw the Territory Combination Product in the applicable country(ies).

(c) Product Withdrawal. Without limitation of Section 13.2(b), the Parties may, for commercial reasons or otherwise, mutually determine to withdraw the Combination Product from the market in one or more countries in the Territory (and to recall the Combination Product in connection therewith, if applicable). If the reason for such market withdrawal is based on any of the Recall/Withdrawal Criteria, such withdrawal shall be conducted in accordance with Section 13.2(b). In all other cases of mutually agreed upon market withdrawal, the Selling Party shall, upon receiving any necessary or appropriate approval from the applicable Regulatory Authority(ies), cease selling (and cause its subdistributors and Third Party Distributors, as applicable, to cease selling) the Combination Product in such country(ies) in the Territory and the Selling Party shall determine whether, and if so how, to recall any Combination Product already on the market in such country(ies).

(e) Regulatory Filings; Required Reporting. In the case of any recall or withdrawal of the Territory Combination Product in any country in the Territory, the Selling Party with respect to such country shall make (or cause to be made) such regulatory filings with Regulatory Authorities in such country as may be required to effect such recall or withdrawal.

(f) Reporting and other Actions Required by Applicable Law. Nothing set forth in this Section 13.2 shall be construed as restricting the right of either Party to make a timely report of such matter to any government agency or take other action that it deems appropriate or required by Applicable Law.

13.3 Recall Expenses. Each Party (the “Responsible Party”) shall bear any and all Recall Expenses with respect to any recall or withdrawal that (a) is caused by one or more of the following: (i) such Party’s (or its Affiliate’s) negligence, gross negligence or willful misconduct or omission, (ii) safety issues with respect to its APIs, (iii) breach by such Party (or its Affiliate or subcontractor) of this Agreement or any Ancillary Agreement, or (iv) any event occurring while the Territory Combination Product is under the control of such Party (or its Affiliate) hereunder or under any Tibotec Distributor Agreement; and (b) is not caused or occasioned by any of the following: (i) the other Party’s (or its Affiliate’s) negligence, gross negligence or willful misconduct or omission, (ii) safety issues with respect to the other Party’s APIs, (iii) the breach by the other Party (or its Affiliate or subcontractor) of this Agreement or any Ancillary Agreement, or (iv) any event occurring while the Territory Combination Product is under the control of the other Party (or its Affiliate) hereunder or under any Tibotec Distributor Agreement (such a recall or withdrawal, a “Party-Specific Recall/Withdrawal”). Any Recall Expenses that are not exclusively borne by one of the Parties pursuant to the preceding sentence shall be borne by the Parties [*] with respect to the Territory. In addition, if any existing Territory Combination Product is rendered unusable as a result of a recall or withdrawal (either by way of a return resulting in unusable Territory Combination Product or an inability to make future sales of Territory Combination Product in inventory) (“Recalled Product”), the following shall apply with respect to the Recalled Product (and the quantity of APIs contained therein): [*].

Each Party shall provide such assistance as may reasonably be required to obtain such extensions.

14.3 Liability for Prosecution and Maintenance. Each Party acknowledges that the Party responsible for prosecution and maintenance of Patents licensed or co-owned under this Agreement or the Ancillary Agreements (the “Prosecution and Maintenance”) does not guarantee the issuance, validity, or enforceability of any such Patent or any claim resulting from its efforts hereunder. Neither Party shall have any liability to the other Party for any negligent acts or misconduct of outside counsel utilized in connection with the Prosecution and Maintenance, provided that the other Party was notified of the selection of such outside counsel and gave consent thereto, not unreasonably withheld. Neither Party shall have any liability to the other Party with respect to the Prosecution and Maintenance to the extent the other Party had an opportunity to review and comment on the communication, filing or submission relevant thereto. The foregoing provisions of this Section 14.3 are without prejudice to either Party’s potential liability for breach of its obligations under Section 14.1 or 14.2.

14.4 Enforcement of Patents.

(a) Gilead Patents. As between the Parties, Gilead shall have the sole right and option, at its sole expense, to respond to any Infringement (as defined below) with respect to any Gilead Patent, including Patents claiming or covering the Gilead-Owned Collaboration Inventions, by appropriate steps, including by filing an infringement suit or taking other similar action. Gilead shall also have the sole right and option not to take any action to respond to any such Infringement (and in such event Tibotec shall not have the right take any action to respond to any Infringement with respect to such Gilead Patent). At Gilead’s request, Tibotec shall, at Tibotec’s own expense, provide reasonable assistance to Gilead in connection with any such action to respond to Infringement, including providing access to relevant documents and other

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

evidence, making its employees available at reasonable business hours, and joining the action to the extent necessary to allow Gilead to maintain the action.

(b) Tibotec Patents.

(i) Infringing Combination Products. As between the Parties, Tibotec shall have the first right and option, at its sole expense, to respond to any Infringement with respect to any Tibotec Patent, including Patents claiming or covering the Tibotec-Owned Collaboration Inventions, by appropriate steps, including by filing an infringement suit or taking other similar action. In the event Tibotec fails within thirty (30) days following notice of such Infringement or following receipt by Tibotec of a Paragraph IV Certification, whichever is later, or earlier notifies Gilead in writing of its intent not, to take commercially appropriate steps to remove any Infringement of any Combination Product-Related Tibotec Patent, then Gilead shall have the right, but not the obligation, to do so at Gilead’s sole cost and expense; provided, however, (except in the case of a Paragraph IV Certification) that if Tibotec has commenced negotiations with an alleged infringer for discontinuance of such Infringement within such thirty (30) day period, Tibotec shall have an additional ninety (90) days to conclude its negotiations before Gilead may bring suit for such Infringement. At the request of the Party bringing the suit or action, the other Party shall, at such other Party’s own expense, provide reasonable assistance to the Party bringing the suit or action in connection with any such suit or action to respond to Infringement, including providing access to relevant documents and other evidence, making its employees available at reasonable business hours, and joining such suit or action to the extent necessary to allow the Party bringing such suit or action to maintain such suit or action.

(ii) Other Infringing Products. As between the Parties, Tibotec shall have the sole right and option, at its sole expense, to respond to any Other Product Infringement with respect to any Tibotec Patent, including Patents claiming or covering the Tibotec-Owned Collaboration Inventions, by appropriate steps, including by filing an infringement suit or taking other similar action. Punitive or enhanced damages recovered by judgment shall be retained by Tibotec. As between the Parties, any other amounts recovered by Tibotec pursuant to this Section 14.4(b)(ii), whether by settlement or judgment, shall first be used to reimburse Tibotec for its costs and expenses in making such recovery. Any remaining recovery shall be retained by Tibotec, provided that any such remaining recoveries with respect to any Other Infringing Product for which [*].

(c) For purposes of this Section 14.4, (i) “Infringement” shall mean infringement or potential infringement of one or more Gilead Patents or one or more Tibotec Patents, as the case may be, by the actions of a Third Party in connection with the Combination Product (an “Infringing Combination Product”) where such infringement or potential infringement relates to the manufacture, importation, sale or offering for sale of such Combination Product in the Territory, (ii) “Other Product Infringement” shall mean infringement or potential infringement of one or more Tibotec Patents by the actions of a Third Party in connection with a product, which is not an Infringing Combination Product, that would be covered by Section 10.4 if Tibotec or its Affiliates had sold such product (an “Other

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Infringing Product”), where such infringement or potential infringement relates to the manufacture, importation, sale or offering for sale of such product in the Territory, and (iii) “other similar action” shall include responses to paragraph (iv) certification under the Drug Price Competition and Patent Term Restoration Act (also known as the Hatch-Waxman Act) (a “Paragraph (iv) Certification”) or a Notice of Allegation, which Paragraph (iv) Certification or Notice of Allegation relates to any such Gilead Patent or Tibotec Patent and results from an attempt to market (A) in the case of an Infringing Combination Product, a Generic Combination Product or (B) in the case of an Other Infringing Product, a generic version (determined in a manner analogous to [*] thereof. For the avoidance of doubt, the Parties acknowledge and agree that infringement of a Gilead Patent or a Tibotec Patent, as the case may be, other than by an Infringing Combination Product, or with respect to the Tibotec Patents, an Other Infringing Product, is outside the scope of this Agreement and shall not create any rights or impose any obligations on the Parties hereunder, including any right or obligation to take actions to respond to such infringement.

(d) Joint Patents. As between the Parties, Gilead, on behalf of and in the name of both Parties as joint owners, shall have the first right and option, at its sole expense, to respond to any infringement with respect to any Joint Patent to the extent relating to the Combination Product by appropriate steps, including filing an infringement suit or taking other similar action, and shall notify Tibotec of, and consult with Tibotec from time to time regarding, any such suit or other action. In the event that Gilead fails within thirty (30) days following notice of such infringement, or earlier notifies Tibotec in writing of its intent not, to take commercially appropriate steps to remove any infringement of any such Joint Patent, then Tibotec shall have the right, but not the obligation, to do so at Tibotec’s sole cost and expense. The Party not bringing the suit or action shall provide, at such Party’s own expense, reasonable assistance to the Party bringing the suit or action, including providing access to relevant documents and other evidence, making its employees available at reasonable business hours, and joining the action to the extent necessary to allow the Party bringing the suit or action to maintain such suit or action.

(e) Paragraph (iv) Certifications; Notices of Allegation. Each Party shall notify the other Party in writing within five (5) Business Days of receiving any Paragraph (iv) Certification or Notice of Allegation with respect to the Combination Product, the TMC278 Product (in the case of Tibotec), or Truvada (in the case of Gilead), as applicable. In the event that a Party provides a notice pursuant to this clause (e) of a Paragraph (iv) Certification or a Notice of Allegation resulting from an attempt to market a Generic Combination Product or a generic version of an Other Infringing Product as described in clause (B) of Section 14.4(c), then the rights and obligations in clauses (a), (b) and (d) of this Section 14.4, as applicable, shall apply with respect to any responses to such Paragraph (iv) Certification or Notice of Allegation to the extent that it relates to any Gilead Patent, Tibotec Patent or Joint Patent, as applicable.

(f) Recoveries. As between the Parties, any amounts recovered by either Party pursuant to this Section 14.4 (other than pursuant to Section 14.4(b)(ii)), whether by

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

settlement or judgment, shall first be used to reimburse the applicable Party(ies) for their costs and expenses in making such recovery (which amounts shall be allocated first to reimburse the costs and expenses of the Party that prosecuted the infringement suit and second to reimburse the costs and expenses of the other Party). Any remaining recovery shall be allocated between the Parties based on the proportion of the Combination Product revenue to which each Party is entitled hereunder or under any Ancillary Agreement, with respect to the applicable country and Calendar Year(s) in which the sales of the Infringing Combination Product occurred; provided, however, that any portion of such remaining recovery that constitutes punitive or enhanced damages recovered by judgment (assuming that recoveries constituting punitive or enhanced damages are first applied to the foregoing costs and expenses) shall be retained by the Party that prosecuted the infringement suit.

14.5 Defense of Patents. In the event that a Third Party asserts, in a declaratory judgment action or similar action or claim filed by such Third Party, that any Gilead Patent, Tibotec Patent or Joint Patent to the extent relating to the Combination Product is invalid or unenforceable, Gilead shall have the right, but not the obligation, at its sole cost and expense, to defend such action or claim made against any Gilead Patent or Joint Patent to the extent relating to the Combination Product, and Tibotec shall have the first right, but not the obligation, at its sole cost and expense, to defend such action or claim made against any Tibotec Patent. In the event Tibotec fails within ninety (90) days following notice of such declaratory judgment action or similar action or claim, or earlier notifies Gilead in writing of its intent not, to take commercially appropriate steps to defend any such action or claim alleging that any Combination Product-Related Tibotec Patent is invalid or unenforceable, then Gilead shall have the right, but not the obligation, to do so at Gilead’s sole cost and expense.

Gilead (or its designee) shall have the sole right, at its sole expense, to search, clear, file, register, prosecute and maintain the Combination Product Trademarks anywhere in the world in the name of Gilead (or its designee).

15.3 Confidential Information.

(a) Defined. “Confidential Information” of a Party shall mean the terms of this Agreement and each Ancillary Agreement and all information provided by or on behalf of such Party (or its Affiliates) to the other Party (or its Affiliates) either in connection with the discussions and negotiations pertaining to this Agreement or any Ancillary Agreement, the MTA or the CDA or in the course of performing this Agreement or any such other agreement, including data; knowledge; practices; processes; ideas; research plans; engineering designs and drawings; research data; manufacturing processes and techniques; scientific, manufacturing, marketing and business plans; and financial and personnel matters relating to the Disclosing Party or to its present or future products, sales, suppliers, customers, employees, investors or business, including any of the foregoing included in any Annexes or Exhibits to this Agreement or any Ancillary Agreement.

Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of a Party or its Affiliate merely because individual elements of such Confidential Information are in the public domain or in the

17.2 Additional Representations, Warranties and Covenants of Tibotec. Tibotec hereby represents, warrants and covenants to Gilead as of the Effective Date as follows:

(a) During the term of this Agreement, without the prior written consent of Gilead (i) Tibotec will not import, sell or offer to sell, and will cause its Affiliates not to import, sell or offer to sell, and (ii) Tibotec will not grant any rights to any Third Party to import, sell or offer to sell, in each case ((i) and (ii)) in the Field anywhere in the world (A) the Combination Product other than pursuant to this Agreement, or (B) any other combination product that is [*]; provided, that this sentence shall not apply to Japan or any of the countries in the Access Territory from and after [*]. For clarity, Tibotec retains rights to Exploit any combination products other than those described in clauses (A) and (B) of this Section 17.2(a).

(b) There are no judgments or settlements against, or amounts with respect thereto owed by, Tibotec relating to the Tibotec Patents. To the knowledge of Tibotec, except as is otherwise disclosed in writing by Tibotec to Gilead on or before the Effective Date, Tibotec has not received written notice of any Proceeding in which it is alleged that, with respect to the Territory (i) any of the Tibotec Patents that are composition of matter Patents are invalid or unenforceable or (ii) the Exploitation of TMC278 (in API or other form), whether alone or in combination with either or both of TDF and FTC, infringes any Third Party Patent (other than any such infringement that would arise from the Exploitation of either or both of TDF and FTC in the absence of the TMC278 (in API or other form)).

(c) To the knowledge of Tibotec, the information contained in its INDs for its Single Agent Product represents, in all material respects, a complete and accurate reflection of the safety and efficacy profile of its Single Agent Product. As of the date of submission of the NDA for its Single Agent Product to the FDA, to the knowledge of Tibotec as of such date, the information contained in such NDA as of such date will represent, in all material respects, a complete and accurate reflection of the safety and efficacy profile of its Single Agent Product as of such date. Tibotec will seek to obtain a label for its Single Agent Product that represents, in all material respects, a complete and accurate reflection of the safety and efficacy profile of its Single Agent Product as of the date that such label is obtained, to the knowledge of Tibotec or its Affiliates as of such date based on the information in the possession of Tibotec or its Affiliates as of such date. Thereafter, Tibotec will use reasonable efforts to maintain its Single Agent Product labels and the Tibotec Regulatory Documentation through updates as needed to ensure that such information continues to represent a complete and accurate reflection in all material respects of the safety and efficacy profile of its Single Agent Product. It is understood and agreed that Tibotec makes the representation, warranty and covenant to Gilead set forth in this Section 17.2(c) solely for purposes of the Parties’ collaboration pursuant to this Agreement, and for no other purpose.

17.3 Additional Representations, Warranties and Covenants of Gilead. Gilead hereby represents, warrants and covenants to Tibotec as of the Effective Date as follows:

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

(a) There are no judgments or settlements against, or amounts with respect thereto owed by, Gilead relating to the Gilead Patents. To the knowledge of Gilead, except as is otherwise disclosed in writing by Gilead to Tibotec on or before the Effective Date, it has not received written notice of any Proceeding in which it is alleged that, with respect to the Territory (i) any of the Gilead Patents that are composition of matter Patents are invalid or unenforceable or (ii) the Exploitation of either TDF or FTC, whether alone or together and whether or not in combination with TMC278, infringes any Third Party Patent (other than any such infringement that would arise from the Exploitation of TMC278 in the absence of TDF and FTC).

(b) To the knowledge of Gilead, the information contained in the labels of Gilead’s Single Agent Products and Double Agent Product and in the NDAs for Gilead’s Single Agent Products and Double Agent Product represents, in all material respects, a complete and accurate reflection of the safety and efficacy profile of Gilead’s Single Agent Products and Double Agent Product. Gilead will use reasonable efforts to maintain its Single and Double Agent Product labels and the Gilead Regulatory Documentation through updates as needed to ensure that such information continues to represent a complete and accurate reflection in all material respects of the safety and efficacy profile of its Single Agent Products and Double Agent Product. It is understood and agreed that Gilead makes the representation, warranty and covenant to Tibotec set forth in this Section 17.3(b) solely for purposes of the Parties’ collaboration pursuant to this Agreement, and for no other purpose.

During the term of this Agreement, except as expressly provided in the TMC278 Supply Agreement, neither Gilead nor any of its Affiliates shall purchase or otherwise acquire (or use any contract manufacturers that have purchased or otherwise acquired), for use in the manufacture of the Combination Product for sale or distribution in the Territory, any TMC278 from any Person other than Tibotec and its Affiliates; provided, however, that Gilead shall have the right to contract with a potential TMC278 supplier and qualify it for supplying TMC278 to Gilead following the termination of Tibotec’s obligation to supply Supplied TMC278 under the TMC278 Supply Agreement.

17.4 Disclaimer. EXCEPT AS SET FORTH IN SECTIONS 17.1 AND 17.2 AND 17.3, EACH PARTY HEREBY DISCLAIMS ANY AND ALL REPRESENTATIONS AND WARRANTIES, WHETHER WRITTEN OR ORAL, OR EXPRESS OR IMPLIED, IN CONNECTION WITH THIS AGREEMENT, INCLUDING WITH RESPECT TO THE SINGLE AGENT PRODUCT(S), THE DOUBLE AGENT PRODUCT, THE COMBINATION PRODUCT OR ANY TIBOTEC TECHNOLOGY, GILEAD TECHNOLOGY, JOINT TECHNOLOGY OR REGULATORY DOCUMENTATION LICENSED UNDER THIS

SECTION 18

INDEMNIFICATION AND INSURANCE

(a) By Each Party. Each Party shall indemnify the other Party and its Indemnified Persons from and against (i) any Proceeding in which such other Party or any of its Indemnified Persons is involved or threatened to be involved to the extent that such Proceeding arises out of or relates to (A) the negligence or willful misconduct of the Indemnifying Party, any of its Affiliates, licensees or subcontractors, in each case in connection with the exercise of such Indemnifying Party’s or any of its Affiliates’ rights, or performance of such Party’s or any of its Affiliates’, obligations, under this Agreement or any Ancillary Agreement, (B) the Indemnifying Party’s or any of its Affiliates’, licensees’ or subcontractor’s failure to comply with or perform one or more of such Party’s or such Affiliate’s, as applicable, covenants in this Agreement or any Ancillary Agreement, or the breach or inaccuracy of one or more of such Party’s or such Affiliate’s, as applicable, representations and warranties in this Agreement or any Ancillary Agreement, (C) Exploitation (by the Indemnifying Party, any of its Affiliates, licensees or subcontractors) of the Joint Technology in connection with such Indemnifying Party’s (or its Affiliate’s) Single Agent Product(s), Double Agent Product (if any) or any other of its products (other than the Combination Product), (D) the violation of Applicable Law by the Indemnifying Party or any of its Affiliates, licensees or subcontractors in connection with the exercise of such Indemnifying Party’s or any of its Affiliates’ rights, or performance of such Party’s or any of its Affiliates’ obligations, under this Agreement or any Ancillary Agreement, (E) a breach by the Indemnifying Party or any of its Affiliates of any contracts that such Indemnifying Party or Affiliate has entered into with a Third Party to the extent relating to the Exploitation of the Territory Combination Product, (F) the marketing, sales or promotional activity, relating to the Combination Product or the TMC278 Product, of the employees and agents of the Indemnifying Party or any of its Affiliates, except (1) to the extent resulting from the reasonable reliance on promotional materials or safety information provided by the Indemnified Party or any of its Indemnified Persons and (2) in the case of the marketing, sales or promotion of the TMC278 Product by Gilead and its Affiliates, any such activity that is consistent with the Product Label and Insert for the TMC278 Product, provided that if any Proceedings or Losses would be covered both by this subsection (F) and by Section 18.2(a) or Section 18.2(b), as the case may be, then Section 18.2(a) or (b), as applicable, shall control and this clause (F) shall not apply), or (G) a breach by the Indemnifying Party or any of its Affiliates of any In-License Agreement of such Party or Affiliate to the extent relating to the Exploitation of the Territory Combination

Product, and (ii) all Losses incurred by the Indemnified Party or any of its Indemnified Persons to the extent arising from any Proceeding covered by the foregoing clause (i).

(b) Limitation. Notwithstanding anything in this Section 18, in no event shall either Party’s obligations of indemnity or reimbursement under this Section 18.1 or any of Sections 18.2, 18.3, 18.4 and 18.5 apply to any Proceeding or Loss to the extent that such Proceeding or Loss was caused by the negligence or willful misconduct of, breach of this Agreement or any Ancillary Agreement by, or violation of Applicable Law by, the other Party or any of its Indemnified Parties.

18.2 Indemnification for Certain Product Liability-Related Matters.

(a) By Gilead. Gilead shall indemnify Tibotec and its Indemnified Persons from and against (i) all Proceedings arising anywhere in the world in which Tibotec or any of its Indemnified Persons is involved or threatened to be involved to the extent such Proceedings arise from personal injury or death caused by Territory Combination Product due to defects or the inherent characteristics thereof, where [*] that such defects or characteristics are the direct result of the incorporation (where, for purposes of this Section 18.2 and Sections 18.3 and 18.4, “incorporation” shall be construed to mean the presence of an API in the Combination Product, not the process whereby such API is included in the Combination Product or the formulation of the Combination Product and “incorporated” shall be construed in a corresponding manner) in the Combination Product of TDF, FTC or both TDF and FTC, in each case without reference to the incorporation in the Combination Product of the Supplied TMC278 (other than any Selected Product Liability Proceedings, which, for purposes of clarity, are provided for in Section 18.3), irrespective of whether such defects or characteristics (or any associated defects or characteristics of TDF or FTC) are [*] (such defects or characteristics, “TDF/FTC Characteristics”), and (ii) all Losses (other than Selected Product Liability Losses) incurred by Tibotec or any of its Indemnified Persons arising from any Proceeding covered by the foregoing clause (i) to the extent arising from TDF/FTC Characteristics.

(b) By Tibotec. Tibotec shall indemnify Gilead and its Indemnified Persons from and against (i) all Proceedings arising anywhere in the world in which Gilead or any of its Indemnified Persons is involved or threatened to be involved to the extent such Proceedings arise from personal injury or death caused by Territory Combination Product due to (A) defects or the inherent characteristics thereof, where [*] that such defects or characteristics are the direct result of the incorporation in the Combination Product of the Supplied TMC278 without reference to the incorporation in the Combination Product of either or both of TDF or FTC (other than any Selected Product Liability Proceedings, which, for purposes of clarity, are provided for in Section 18.3), irrespective of whether such defects or characteristics (or any associated defects or characteristics of the Supplied TMC278) are [*] (such defects or characteristics, “TMC278 Characteristics”) or (B) the Label Characteristics (as defined below), and (ii) all Losses (other than Selected Product Liability Losses) incurred by Gilead or any of its Indemnified Persons arising from any Proceeding covered by the foregoing clause (i) to the extent arising from TMC278 Characteristics or the Label Characteristics. “Label Characteristics” shall mean the

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

failure of the label of Tibotec’s Single Agent Product to represent, in all material respects and [*], a complete and accurate reflection of the safety and efficacy profile of Tibotec’s Single Agent Product as of such date, which failure leads to the failure of the label of the Territory Combination Product to represent, in all material respects and [*], a complete and accurate reflection of the safety and efficacy profile of the TMC278 portion of the Combination Product as of such date.

18.3 Selected Product Liability Losses. Any Selected Product Liability Losses shall be borne by Gilead and Tibotec in accordance with [*] with respect to the Territory. “Selected Product Liability Losses” shall mean any Losses arising out of any Selected Product Liability Proceeding. “Selected Product Liability Proceeding” shall mean any Proceeding arising anywhere in the world in which any Party or any of its Indemnified Persons is involved or threatened to be involved to the extent such Proceedings arise from personal injury or death caused by Territory Combination Product due to defects or the inherent characteristics of the Combination Product, (a) where [*] such defects or characteristics are the direct result of both (i) the Supplied TMC278 and (ii) either or both of TDF or FTC being incorporated into the Combination Product, (b) where it ultimately cannot be or is not determined whether such defects or characteristics are the direct result of the Supplied TMC278, on the one hand, or either or both of TDF and FTC, on the other hand, being incorporated into the Combination Product, or (c) where such defects or characteristics are the direct result of an aspect of the Combination Product other than any of its APIs, except, in each case ((a), (b) and (c)), to the extent such Proceeding arises from personal injury or death caused by Territory Combination Product due to the Label Characteristics, which Proceeding is covered in Section 18.2(b).

18.4 Third Party Infringement Losses.

(a) By Gilead. Gilead shall indemnify Tibotec and its Indemnified Persons from and against (i) any Proceeding arising anywhere in the world in which Tibotec or any of its Indemnified Persons is involved or threatened to be involved to the extent that (A) such Proceeding arises out of an allegation that any Exploitation of Territory Combination Product infringes or misappropriates, or will infringe or misappropriate, any patent or other intellectual property, including trade secrets, of a Third Party, and (B) (x) such Proceeding is a direct result of TDF, FTC or both TDF and FTC being incorporated into the Territory Combination Product, in each case without reference to the Supplied TMC278 or (y) such Proceeding is the direct result of (1) the process whereby any such API is included in the Combination Product or (2) the formulation of the Combination Product, and (ii) all Losses arising from such a Proceeding incurred by Tibotec or any of its Indemnified Persons, as the case may be, to the extent arising as a direct result of a cause described in either clause (x) or (y) above.

(b) Combination Product Trademark. Gilead shall indemnify Tibotec and its Indemnified Persons from and against (i) any Proceeding arising anywhere in the world where Tibotec is licensed by Gilead to use the Combination Product Trademark in which Tibotec or any of its Indemnified Persons is involved or threatened to be involved to the extent that such Proceeding arises out of an allegation that the use of the Combination Product Trademark

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

infringes or dilutes the Trademark rights of any Third Party, and (ii) all Losses arising from such a Proceeding incurred by Tibotec or any of its Indemnified Persons, as the case may be, to the extent arising as a direct result of such use.

(c) By Tibotec. Tibotec shall indemnify Gilead and its Indemnified Persons from and against (i) any Proceeding in which Gilead or any of its Indemnified Persons is involved or threatened to be involved to the extent that (A) such Proceeding arises out of an allegation that any Exploitation of any Territory Combination Product infringes or misappropriates, or will infringe or misappropriate, any patent or other intellectual property, including trade secrets, of a Third Party and (B) such Proceeding is a direct result of the Supplied TMC278 being incorporated into the Territory Combination Product, in each case without reference to TDF or FTC, and (ii) all Losses arising from such a Proceeding incurred by Gilead or any of its Indemnified Persons, as the case may be, to the extent arising as a direct result of the Supplied TMC278 being incorporated into the Combination Product, in each case without reference to TDF or FTC.

(d) Shared Infringement Losses. To the extent that (i) any Losses arising out of any Proceeding against any Party or any of its Indemnified Persons arise out of an allegation that the Exploitation of any Territory Combination Product infringes or misappropriates, or will infringe or misappropriate, any patent or other intellectual property, including trade secrets, of a Third Party, and (ii) such Losses are not covered by Section 18.1, 18.4(a), 18.4(b) or 18.4(c), such Losses shall be borne by the Parties [*].

18.5 Other Shared Combination Product-Related Losses. With respect to any Losses arising out of any Proceeding brought or made against any Party or any of its Indemnified Persons to the extent arising out of the Exploitation of Territory Combination Product (including (a) any Manufacture of any Territory Combination Product, and (b) any activities performed by or on behalf of any Party, in its capacity as the MA Holder), except to the extent that either Party has an obligation of indemnification with respect to such Losses pursuant to any of Section 18.1 through 18.4, Gilead and Tibotec shall each bear such portion of such Losses [*].

18.6 Indemnification Procedure. The indemnity and reimbursement obligations of a Party under this Section 18 shall be governed by the following:

(a) Notice. In the case of any Proceeding for which an Indemnifying Party may be liable to an Indemnified Person under this Section 18, the Indemnified Party shall as soon as practicable notify the Indemnifying Party in writing of such Proceeding (a “Notice of Claim”). Failure or delay in notifying the Indemnifying Party shall not relieve the Indemnifying Party of any liability it may have to the Indemnified Party, except and only to the extent that such failure or delay causes actual harm to the Indemnifying Party with respect to such Proceeding. The Notice of Claim shall specify in reasonable detail the Proceeding with respect to which such Indemnified Party or any of its Indemnified Persons intends to base a request for indemnification or reimbursement under this Section 18. Failure to provide such reasonable detail will not relieve the Indemnifying Party of any liability it may have to the Indemnified

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Party, except and only to the extent that such failure causes actual harm to the Indemnifying Party with respect to such Proceeding. The Indemnified Party shall enclose with the Notice of Claim a copy of all papers served with respect to such Proceeding, if any. The Indemnifying Party shall have thirty (30) days from the date on which the Indemnifying Party received the Notice of Claim to notify the Indemnified Party that the Indemnifying Party desires to assume the defense of such Proceeding and any litigation resulting therefrom with counsel of its choice.

(b) Control of the Third Party Defense. If the Indemnifying Party has given the Indemnified Party notice pursuant to Section 18.6(a) that it desires to assume control of a Proceeding and the Indemnifying Party has acknowledged in writing an obligation to indemnify or reimburse fully the Indemnified Party or its applicable Indemnified Person(s) for all Losses arising from the Proceeding (to the extent such Losses and Proceedings are covered by such Indemnifying Party’s indemnity obligations under Sections 18.1, 18.2 and 18.4), then, subject to Section 18.6(d), the Indemnifying Party shall have the right to defend, settle and otherwise dispose of such Proceeding (such Party, “Defending Party”). If the Indemnifying Party provides notice that it desires to assume control of the Proceeding, but the Indemnifying Party does not have the right to be the Defending Party pursuant to the preceding sentence, or if Losses are to be allocated under Section 18.3, 18.4(d) or 18.5, then the Parties shall confer and negotiate in good faith to determine whether to enter into a joint defense agreement pursuant to which the Parties shall allocate the respective rights and obligations of the Parties with respect to the control of the Proceeding, including whether to designate one of the Parties as the Defending Party. In the event that there are two or more Indemnified Parties or Indemnified Persons that are subject to the same Proceeding, this Section 18.6 shall be construed to apply separately to such Proceeding as it applies to each such Indemnified Party or Indemnified Person, provided that the applicable Parties agree to take account of such fact in connection with their negotiations pursuant to this Section 18.6(b) with respect to the defense, control and settlement of such Proceeding as it applies to each such Indemnified Party or Indemnified Person. The out-of-pocket costs and expenses (including reasonable attorneys’ fees) reasonably incurred by the Defending Party in connection with its control of a Proceeding shall constitute Losses with respect to such Proceeding.

(c) Interim Control. Unless and until the Defending Party is determined, the Indemnified Party subject to such Proceeding shall have the right to defend and control such Proceeding, but shall not have the right to consent to the entry of any judgment or enter into any settlement with respect to the Proceeding for which it would be seeking indemnification or reimbursement hereunder (including under Section 18.3, 18.4(d) or 18.5) without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed).

(d) Control by the Indemnifying Party. If either Party is the Defending Party, (i) the other Party may retain separate co-counsel at (from and after such assumption) its sole cost and expense and participate in the defense of the Proceeding but the Defending Party shall control the investigation, defense and settlement thereof, (ii) the other Party will not consent to

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

the entry of any judgment or enter into any settlement with respect to the Proceeding for which it would be seeking indemnification or reimbursement hereunder without the prior written consent of the Defending Party (which consent shall not be unreasonably withheld, conditioned or delayed) and (iii) the Defending Party will not, without the prior written consent of the other Party, consent to the entry of any judgment or enter into any settlement with respect to the Proceeding to the extent such judgment or settlement (A) provides for equitable relief (or any other relief other than solely for money damages), or for any monetary relief that will not be fully discharged by the Defending Party (without any recourse to the other Party) concurrently with the effectiveness of such judgment or settlement; provided that the other Party’s consent shall not be unreasonably withheld, conditioned or delayed to the extent that the sole relief is monetary, or (B) does not effect a full and unconditional release of the other Party and its Indemnified Persons with respect to all claims in such Proceeding (or the portion thereof to which the judgment or settlement relates). The Parties shall act in good faith in responding to, defending against, settling or otherwise dealing with such Proceeding; provided, that (A) an Indemnified Party shall not be obligated pursuant to this sentence to enter into or consent to the entry of any judgment or settlement in relation to any Proceeding and (B) in any event, an Indemnifying Party shall not be relieved of its obligations under this sentence as a result of any breach of this sentence (determined after giving effect to clause (A)) except to the extent that the Indemnifying Party is actually prejudiced by such breach. Notwithstanding anything contained herein to the contrary, an Indemnifying Party shall not be entitled to assume the defense of any Proceeding that seeks an injunction or other equitable relief (or any other relief other than solely money damages) against the other Party. The Parties shall also cooperate in any such defense and give each other reasonable access to all non-privileged information relevant thereto to the extent permitted by applicable law.

(e) Election Not to Control. If there is no Defending Party with respect to a given Proceeding, then the Indemnified Party will be entitled to assume control of the Proceeding, at its cost and expense (or to the extent the Indemnified Party is entitled to indemnification or reimbursement with respect thereto pursuant to this Section 18, at the expense of the other Party to such extent) upon delivery of notice to such effect to the other Party; provided that the Indemnifying Party shall have the right to participate in the Proceeding at its sole cost and expense, but the Indemnified Party shall control the investigation, defense and settlement thereof.

(f) Unauthorized Settlements. Whether or not the Indemnifying Party has assumed control of the Proceeding, such Indemnifying Party shall not be obligated to indemnify or reimburse the Indemnified Party hereunder for any settlement entered into, or any judgment that was consented to, by the Indemnified Party without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

(g) Allocations. The allocation between the Parties (whether by indemnification, reimbursement or otherwise) of any liability for any Losses, if not otherwise determined in a court of law, shall be considered by the Parties and, if the Parties do not reach

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

agreement in writing on such allocation, either Party shall have the right to refer the dispute to arbitration pursuant to Section 20.7. The Parties or the arbitrator, as the case may be, shall make such allocation based on the indemnification and reimbursement principles set forth in this Section 18. The dispute resolution procedures in Section 2.4 shall not apply to any disputes arising under this Section 18.6(g). Notwithstanding the foregoing, the Parties shall not be entitled to refer any dispute with respect to Losses arising under a Proceeding pursuant to this Section 18.6(g) to arbitration to the extent that the liability of either Party for such Losses is being contested in such Proceeding (or any other Proceeding that would be binding with respect to such first Proceeding).

(h) Third Party Rights. The Parties shall attempt in good faith to coordinate with respect to the rights set forth in this Section 18.6, including any rights with respect to the control of any applicable Proceeding, to take into account the rights of any Third Party (e.g., a subcontractor of a Party) that has an obligation to indemnify any Party (or its Indemnified Persons) with respect to any Losses covered by this Section 18.

18.7 LIMITATION ON DAMAGES. EXCEPT WITH RESPECT TO LIABILITY ARISING FROM BREACHES OF SECTION 15 BY A PARTY, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE, MULTIPLIED OR CONSEQUENTIAL DAMAGES (INCLUDING FOR LOST PROFITS), WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, ARISING IN CONNECTION WITH THIS AGREEMENT OR ANY ANCILLARY AGREEMENT. NOTHING IN THIS SECTION 18.7 IS INTENDED TO OR SHALL OPERATE TO LIMIT A PARTY’S OBLIGATIONS OF INDEMNITY OR REIMBURSEMENT OF LOSSES UNDER THIS SECTION 18.

18.8 Insurance. Each Party shall maintain during the term of this Agreement and for a period of at least five years thereafter product liability insurance on an occurrences reported or a claims-made coverage form with limits of not less than [*] per occurrence and annual aggregate. If such coverage is written on a claims-made basis, the retroactive date, if any, shall precede the Effective Date. In addition, a [*] extended reporting period shall be purchased if the policy or policies are cancelled or not renewed and not replaced by another claims-made policy with the same (or earlier) retroactive date. Such insurance shall include worldwide coverage. If commercially reasonable insurance is unavailable, each Party may elect to self-insure its respective risks. Each Party shall provide the other with thirty (30) days’ prior written notice in the event of cancellation of or material change in such insurance. Each Party shall, upon the written request of the other, provide the other with written evidence of insurance coverage meeting the above criteria. To the extent that either Party insures its respective risks and exposures arising out of the Exploitation of the Combination Product, the Party obtaining such insurance or self-insuring for such exposures shall have the sole right to retain any recoveries under such policies or programs. For the avoidance of doubt, nothing contained in this Section 18.8 is intended, or shall be construed, to limit a Party’s indemnity obligations or obligation to share Losses pursuant this Section 18.

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

18.9 Quality Agreements. For clarity, no Indemnified Party shall be entitled to indemnification pursuant to Section 18.1 based solely on a breach of a Quality Agreement. Further, each Party shall, and shall cause its Affiliates to, refrain from seeking damages or any other remedy under any Quality Agreement.

SECTION 19

TERM AND TERMINATION

19.1 Term. The term of this Agreement shall commence as of the Effective Date and shall continue until terminated pursuant to this Section 19.

19.2 Challenge by Governmental Authority. In the event that any governmental authority in a country obtains a preliminary injunction or permanent injunction enjoining the transactions between the Parties in connection with entering into this Agreement, the Parties shall meet and discuss whether to terminate this Agreement with respect to such country.

19.3 Combination Product Withdrawal. Either Party may terminate this Agreement, with respect to a country, if (a) the Territory Combination Product is withdrawn from the market in such country for reasons of safety or efficacy or (b) the Territory Combination Product is withdrawn in a Major Market for reasons of safety or efficacy. In such event, termination shall be effective immediately upon written notice from the terminating Party.

19.4 Material Breach.

(a) Notice and Cure Period. If a Party (the “Breaching Party”) is in Material Breach, the other Party (the “Non-Breaching Party”) shall have the right to give the Breaching Party notice specifying the nature of such Material Breach. Except as set forth in Section 6.2(b)(v) with respect to Initial Specific Target Breaches, the Breaching Party shall have a period of ninety (90) days after receipt of such notice to cure such Material Breach (including Commercial Target Breaches other than Initial Specific Target Breaches) (the “Cure Period”) in a manner reasonably acceptable to the Non-Breaching Party. For the avoidance of doubt, this provision is not intended to restrict in any way either Party’s right to notify the other Party of any other breach or to demand the cure of any other breach.

(b) Termination Right. The Non-Breaching Party shall have the right to terminate this Agreement, upon written notice to the Breaching Party, in the event that the Breaching Party has not, in the case of an Initial Specific Target Breach, cured such Material Breach within the applicable time period set forth in Section 6.2(b)(v), or in the case of any other Material Breach, cured such Material Breach within the Cure Period. If a Party contests such termination pursuant to the escalation procedures under Section 2.4 or under Section 20.7, such termination shall not be effective until a conclusion of the procedures in Section 2.4 and Section 20.7, as applicable, resulting in a determination that there has been an uncured Material Breach (or, if earlier, abandonment of the dispute by such Party). If the Breaching Party asserts that the

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

Such termination shall be effective as of the date of such notice.

(c) Either Party may, by written notice to the other Party, terminate this Agreement in its entirety at any time prior to the earlier of the first Approval for the Combination Product in the Field in the US or the first marketing authorization for the Combination Product in the Field by the European Commission if either the FDA or the EMEA requires (i) for, or as a condition of, Approval or marketing authorization of the Combination Product in the Field in the United States or the European Union, as applicable, any Clinical Trials or studies other than the activities contemplated in Section 3.2(a) and Section 3.2(b)(i), or (ii) for, or as a condition of, Approval of marketing authorization of the TMC278 Product in the Field in the United States or the European Union, as applicable, any Clinical Trials or studies other than the Ongoing TMC278 Studies or such other studies as Tibotec would be obligated to perform under Section 3.1(a), and, in the case of clause (i), Gilead is unwilling to conduct such Clinical Trials or studies, and, in the case of clause (ii), regardless of whether Tibotec is willing to conduct such Clinical Trials or studies. Such termination shall be effective as of the date of such notice.

obtain the exclusive rights to do so and would pay to Gilead a portion of the Combination Product revenue to be determined during the course of such negotiation [*].

SECTION 20

GENERAL PROVISIONS

20.1 Force Majeure. Neither Party shall be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement, except for the payment of any amounts under this Agreement, when such failure or delay is caused by or results from causes beyond the reasonable control of the non-performing Party, including fires, floods, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorism, insurrections, riots, civil commotion, acts of God or acts, omissions or delays in acting by any governmental authority. The non-performing Party shall notify the other Party of such force majeure within five (5) days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use, throughout the period of suspension of performance, commercially reasonable efforts to remedy its inability to perform; provided, however, that in the event the suspension of performance continues for ninety (90) days after the date such force majeure commences, the Parties shall meet to discuss in good faith how to proceed in order to accomplish the objectives of this Agreement; and provided, further, however, that if the suspension of performance continues for more than one (1) year after the date such force majeure commences, either Party shall have the right to terminate this Agreement upon notice to the other Party. Upon such termination, the provisions of Section 19.6(b) shall apply and any amounts remaining to be paid by Gilead pursuant to Section 10.1 shall be canceled (but any amounts theretofore paid pursuant to Section 10.1 may be retained by Tibotec).

It is understood and agreed that this Section 20.2 is not intended to govern the day-to-day business communications necessary between the Parties in performing their duties, in due course, under the terms of this Agreement. Whenever this Agreement requires or permits the giving of notice by or to Gilead, such notice may be given by or to Gilead Parent on behalf Gilead.

20.3 Further Assurances. Each Party shall use commercially reasonable efforts to duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further ministerial, administrative or similar acts and things, including the filing of such assignments, agreements, documents and instruments, as may be necessary, or as the other Party may reasonably request, to carry out more effectively the provisions and purposes hereof, or to better assure and confirm unto such other Party its rights and remedies under this Agreement.

20.4 Guarantee. Tibotec shall cause [*] to, and Gilead Parent shall, enter into a guarantee agreement substantially in the form of Annex U.

20.5 Successors and Assigns. The terms and provisions hereof shall inure to the benefit of, and be binding upon, the Parties and their respective successors and permitted assigns. Except as expressly permitted pursuant to Sections 3.3, 4.1(b) and 6.2(c) or otherwise in this Agreement, neither Party may, without the prior written consent of the other Party, assign or otherwise transfer any of its rights and interests or subcontract or otherwise delegate any of its obligations under this Agreement. Notwithstanding the foregoing, (i) either Party, without such consent, may assign its rights and delegate its duties under this Agreement to an Affiliate which is a directly or indirectly wholly-owned subsidiary of Gilead Parent or Tibotec Parent, as the case may be; provided, that, except as set forth in clause (ii) below, such assignment or delegation to an Affiliate shall terminate automatically at such time, if any, as such Affiliate ceases to be wholly-owned, directly or indirectly, by Gilead Parent or Tibotec Parent, as the case may be, unless such Affiliate owns substantially all the assets of Gilead or Tibotec, as the case may be, that are described in clause (ii)(A)(1) or (ii)(A)(2), respectively, and (ii) each of Gilead and Tibotec, without the prior written consent of the other, may assign its rights and delegate its

107

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

duties under this Agreement, whether by contract or operation of law, (A) to any Third Party that acquires (through the purchase of assets, stock or otherwise) substantially all of the assets of such Party related to (1) in the case of Gilead, [*], and (2) in the case of Tibotec, [*], or (B) in connection with a merger or consolidation of (1) in the case of Gilead as the assigning Party, Gilead Parent, or (2) in the case of Tibotec as the assigning Party, Tibotec, with or into any Third Party, to such Third Party or to the surviving entity in such merger or consolidation with such Third Party. For purposes of the foregoing proviso and clause (ii)(A) of this Section 20.5, “Tibotec” shall refer to the Affiliate(s) of Tibotec Parent which have rights or obligations under this Agreement, and “Gilead” shall refer to the Affiliate(s) of Gilead Parent which have rights or obligations under this Agreement. Any permitted delegee of obligations hereunder shall, in a writing delivered to the other Party at the time of such delegation, expressly assume performance of such obligations. Any purported assignment, transfer, subcontract or delegation by either Party in violation of the terms of this Section 20.5 shall be null and void and of no legal effect. In the event that a Party delegates any of its obligations under this Agreement to a subcontractor, or makes any other assignment of this Agreement (other than pursuant to clause (ii)(B) above), the delegating or assigning Party shall remain primarily (and not secondarily or derivatively) liable for the full and timely performance by such subcontractor or assignee of all such Party’s obligations under this Agreement. For clarity, for purposes of this Agreement, neither Party nor any of its Affiliates shall constitute a subcontractor of the other Party or any of its Affiliates and no activity performed by a Party or its Affiliates shall be deemed performed “on behalf” of the other Party.

20.6 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without reference to the rules of conflict of laws thereof.

20.7 Arbitration.

(a) Arbitration Matters shall be referred initially to the Executives as provided in Section 2.4. If such Arbitration Matter is not resolved as provided in Section 2.4, then, unless the Parties agree in writing to alternate provisions, such Arbitration Matter shall (subject to the limitations in Section 2.4) be resolved exclusively through binding arbitration pursuant to the Non-Administered Arbitration Rules then in effect of the International Institute for Conflict Prevention and Resolution (“CPR”) (available at http://www.cpradr.org), or successor, except where those rules conflict with these provisions, in which case these provisions control. The arbitration will be held in New York, New York.

(b) The panel shall consist of three arbitrators chosen from the CPR Panels of Distinguished Neutrals (unless the Parties agree on the selection of the arbitrators) each of whom shall be a lawyer with at least fifteen (15) years experience with a law firm or corporate law department of over twenty-five (25) lawyers or who was a judge of a court of general jurisdiction. In the event the aggregate damages sought by the claimant are stated to be less than five million U.S. Dollars ($5,000,000), and the aggregate damages sought by the counterclaimant are stated to be less than five million U.S. Dollars ($5,000,000), and neither side seeks equitable

108

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

relief, then a single arbitrator shall be chosen, having the same qualifications and experience specified above. Each arbitrator shall be impartial and independent of the Parties and shall abide by the Code of Ethics for Arbitrators in Commercial Disputes (available at http://www.adr.org/EthicsAndStandards).

(c) In the event the Parties cannot agree upon selection of the arbitrator(s), the CPR will select arbitrator(s) as follows: CPR shall provide the Parties with a list of no less than twenty-five (25) proposed arbitrators (fifteen (15) if a single arbitrator is to be selected) having the credentials referenced above. Within fifteen (15) days of receiving such list, the Parties shall rank at least sixty-five percent (65%) of the proposed arbitrators on the initial CPR list, after exercising cause challenges. The Parties may then jointly interview the five candidates (three if a single arbitrator is to be selected) with the highest combined rankings for no more than one hour each and, following the interviews, may exercise one peremptory challenge each. The panel will consist of the remaining three candidates (or one, if one arbitrator is to be selected) with the highest combined rankings. In the event these procedures fail to result in selection of the required number of arbitrators, CPR shall select the appropriate number of arbitrators from among the members of the various CPR Panels of Distinguished Neutrals, allowing each side challenges for cause and one peremptory challenge each.

(d) The Parties agree to cooperate (i) to attempt to select the arbitrator(s) by agreement within thirty (30) days of initiation of the arbitration, including jointly interviewing the final candidates, (ii) to meet with the arbitrator(s) within thirty (30) days of selection and (iii) to agree at that meeting or before upon procedures for discovery and as to the conduct of the hearing which will result in the hearing being concluded within no more than six (6) months after selection of the arbitrator(s) and in the award being rendered within sixty (60) days of the conclusion of the hearings, or of any post-hearing briefing, which briefing will be completed by both sides within thirty (30) days after the conclusion of the hearings.

(e) In the event the Parties cannot agree upon procedures for discovery and conduct of the hearing meeting the schedule set forth in Section 20.7(d), then the arbitrator(s) shall set dates for the hearing, any post-hearing briefing, and the issuance of the award following the schedule set forth in Section 20.7(d) as closely as practical. The arbitrator(s) shall provide for discovery according to those time limits, giving recognition to the understanding of the Parties that they contemplate reasonable discovery, including document demands and depositions, but that such discovery will be limited so that the schedule set forth in Section 20.7(d) may be met without difficulty. In no event will the arbitrator(s), absent agreement of the Parties, allow more than a total of ten days for the hearing or permit either side to obtain more than a total of forty (40) hours of deposition testimony from all witnesses, including both fact and expert witnesses, or serve more than twenty (20) individual requests for documents, including subparts. There shall be no requests for admission or interrogatories. Multiple hearing days will be scheduled consecutively to the greatest extent possible. The arbitrator(s) shall have power to exclude evidence on grounds of hearsay, prejudice beyond its probative value, redundancy, or irrelevance and no award shall be overturned by reason of any ruling on

109

(b) Notwithstanding anything in this Agreement to the contrary, any Patent Matter with respect to a given Patent shall be subject to adjudication in accordance with the laws of the country in which such Patent is pending or has been issued. The Parties agree that the venue of any such adjudication involving a Patent pending in or issued by the United States shall be a U.S. federal district court sitting in the City of New York, State of New York, and for a Patent pending in or issued by any other country, any competent court having jurisdiction over the subject of the Patent Matter sitting in the capital of such country (or if there is not any such competent court in the capital, a location reasonably proximate to the capital) and each Party irrevocably submits to the jurisdiction of such court. Each Party agrees not to raise any objection at any time to the laying or maintaining of the venue of any action, suit or proceeding for such purpose in any such court, irrevocably waives any claim that such action, suit or other proceeding has been brought in an inconvenient forum, including any forum non conveniens argument, and further irrevocably waives the right to object, with respect to such action, suit or other proceeding, that such court does not have any jurisdiction over such Party.

20.9 Waiver. A Party’s failure to enforce, at any time or for any period of time, any provision of this Agreement, or to exercise any right or remedy, does not constitute a waiver of such provision, right or remedy, or prevent such Party thereafter from enforcing any or all provisions and exercising any or all other rights and remedies. The exercise of any right or remedy does not constitute an election or prevent the exercise of any or all rights or remedies, all rights and remedies being cumulative.

20.10 Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect, then, to the fullest extent permitted by Applicable Law, (a) all other provisions hereof shall remain in full force and effect and shall be liberally construed in order to carry out the intent of the Parties as nearly as may be possible, and (b) the Parties agree to use commercially reasonable efforts to negotiate a provision, in replacement of the provision held invalid, illegal or unenforceable, that is consistent with Applicable Law and accomplishes, as nearly as possible, the original intention of the Parties with respect thereto. Without limitation of the foregoing, if any aspect of Section 7, Section 10, Section 11, Annex J or Annex R is held to be invalid, illegal or unenforceable in any respect, then the Parties agree to negotiate replacement provisions that preserve, as nearly as possible, consistent with Applicable Law, the economic benefit to each Party as those set forth therein. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof prohibited or unenforceable in any respect.

20.11 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of which, taken together, shall constitute one and the same instrument.

20.12 Construction. Except where the context otherwise requires, wherever used the singular shall include the plural, the plural the singular, and the use of any gender shall be applicable to all genders. The words “hereof” and “hereunder”, and words of similar import, shall be construed to refer to this Agreement (including the Annexes hereto) as an entirety and

not to any particular provision. The word “including” as used herein shall mean, including, without limiting the generality of any description preceding such term. The word “or” is used in the inclusive sense (and/or). The captions of this Agreement are for convenience of reference only and in no way define, describe, extend or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. Any reference in this Agreement to a matter or action being subject to the “mutual agreement” or “mutual consultation” of the Parties, or words of similar import, shall not be construed as an agreement that the Parties shall agree to such matter or action. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party.

20.13 Status of the Parties. Neither Party shall have the right to enter into any agreements or take action on behalf of the other Party, nor shall it represent to any Person that it has any such right or authority. Nothing in this Agreement shall be construed as establishing a partnership or joint venture relationship between the Parties.

20.14 Entire Agreement. This Agreement (including the Annexes hereto), together with the Ancillary Agreements executed on or before the Effective Date by the Parties, constitutes, on and as of the Effective Date, the entire agreement of the Parties with respect to the subject matter hereof, and all prior or contemporaneous understandings or agreements between Gilead, on the one hand, and Tibotec, on the other hand (including the CDA and the MTA), whether written or oral, with respect to such subject matter are hereby superseded in their entireties; provided, however, that the CDA shall be superseded solely to the extent applicable to the subject matter of this Agreement. This Agreement shall not be amended in any respect whatsoever except by a further agreement, in writing, fully executed by Gilead and Tibotec.

20.15 Third Parties. Except as set forth in Section 18 as to those Third Parties expressly referred to therein, the agreements, covenants, warranties and representations contained herein are for the benefit of the Parties only and are not for the benefit of any Third Parties.

Unless otherwise agreed, such surveys shall be at the sponsoring Party’s sole expense, the results need not be shared with the other Party, and such surveys shall not be deemed to determine Aided Physician Awareness.

Required Minimum Details

1. Minimum Details. For each Major Market, for each applicable Detailing Year, through the Calendar Quarter that includes the last day of the Launch Period, Gilead shall perform the number of Details of the Combination Product in such Major Market as set forth below (which amounts shall be prorated for any partial Detailing Year):


i.	United States	*[]**

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

of a Detailing Year made by Gilead in a Major Market applicable to meeting the requirements of this Annex F and (b) whether or not the other requirements of Section 6.2(b)(iii) are satisfied. Any such audit shall be conducted during normal business hours at Gilead’s facilities by a reputable independent Third Party selected by Tibotec and reasonably acceptable to Gilead (the “Auditor”). Such Auditor shall sign a confidentiality agreement in a form reasonably satisfactory to Gilead, and shall not disclose to Tibotec or any other person any information, except the number of Details made by Gilead per Major Market for each applicable quarter of a Detailing Year determined by such audit, and the Auditor’s findings as to whether or not the other requirements of Section 6.2(b)(iii) are satisfied. Such audit shall be at Tibotec’s expense, unless the Auditor determines (absent manifest error on the part of the Auditor) that Gilead incorrectly over-reported (i) the number of Details made by Gilead for a particular Major Market and Detailing Year and did not meet the number of Details required for such Major Market and Detailing Year, and/or (ii) meeting the requirements of Section 6.2(b)(iii), in either of which cases Gilead shall be responsible for reimbursing Tibotec for the fees and expenses charged by the Auditor in connection with such audit that are applicable to such Major Market and Detailing Year.

Annex G

Calculation of Net Sales and Net Selling Prices

Capitalized terms not defined in this Annex shall have the meanings set forth in the agreement to which this Annex is attached (the “Agreement”).

1. “Net Sales” shall mean, with respect to a product for any period for a country, expressed in local currency in such country, the gross amount invoiced for commercial sales of such product in such period by the applicable selling Party or any of its Affiliates to Third Parties (for clarity, excluding in the case of the Combination Product any amounts of Combination Product supplied to (or Manufactured by) the Selling Party and distributed pursuant to Section 6.10(a) or (b) of the Agreement) (“Gross Sales”), less charges, if any, to the applicable Third Party for freight, postage, shipping and insurance expenses (if separately identified in such invoice) and less deductions for: (a) normal and customary quantity or cash discounts and sales returns and allowances, including those granted on account of prompt payment, price adjustments, billing errors, permitted customer rejections or returns, including due to a recall or product withdrawal, for a given quantity of the applicable product, administrative fees or reimbursements or similar payments to wholesalers or other distributors, buying groups, pharmacy benefit management organizations, health care insurance carriers or other institutions; allowances, rebates, fees paid to distributors and chargebacks allowed or given; (b) customs or excise duties or other duties related to the sales making up the gross invoice amount (if separately identified in such invoice); (c) any rebates or similar payments accrued with respect to sales paid for by any governmental or regulatory authority; (d) sales and other taxes and duties directly related to the sale, to the extent that such items are included in the gross invoice amount (but not including taxes assessed against the income derived from such sale); and (e) any other item taken as a deduction to determine net sales under GAAP. The foregoing shall be calculated in accordance with GAAP (unless otherwise agreed by the Parties (or their respective Affiliates) pursuant to Section 3 of this Annex). Any of the deductions listed above that involves a payment by such Party shall not be taken as a deduction prior to the date accrued in accordance with GAAP; provided, however that returns shall be deducted based on the actual returns rather than on the basis of the GAAP accruals approach. Further, for purposes of determining Net Sales with respect to a product, the product shall be deemed to be sold when the revenue obtained in connection with the transfer of such product to a Third Party is recognized in accordance with GAAP. Net Sales with respect to a product for any period for the Territory as a whole shall be expressed in U.S. Dollars and, in the case of the Territory Combination Product, shall be equal to the sum of Net Sales of the Territory Combination Product (as converted into U.S. Dollars on a monthly basis using the actual average daily exchange rate for the applicable month for converting the applicable currency into U.S. Dollars, as such rate is reported in Bloomberg Professional (R) service application) in each country in the Territory for such period.

2. “Net Selling Price” shall mean, for any product, for any country in the Territory for any period, expressed in the applicable local currency, the quotient of (i) the aggregate Net Sales for such country of such product for such period, divided by (ii) the number of Units of such product

Annex G Page 1

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

for which revenue has been recognized by the applicable Party in accordance with GAAP for such period that may be sold or used for commercial purposes in such country. (For clarity, donations and patient assistance quantities of Territory Combination Product are subject to Section 6.10 of the Agreement.)

3. Harmonization.

Notwithstanding any of the foregoing, in the case of determining Net Sales of the Territory Combination Product or any product covered by [*] for purposes of the Agreement (or any Ancillary Agreement), the Parties shall coordinate in good faith to harmonize their respective practices in the calculation of Net Sales in a country, such that each Party’s method of calculating Net Sales (for the Territory Combination Product, [*] includes or excludes the same categories or types of deductions as the other Party’s method.

4. “Net Component Price” shall mean, with respect to a Customer and a country, expressed in local currency, the average net price charged to such Customer for the TMC278 Product or Truvada, as the case may be, in such country during the most recently completed Calendar Quarter as to which data are available to allow such calculation, which price shall be calculated by Tibotec (for the TMC278 Product) or Gilead (for Truvada) based on the data and information maintained by it (and its applicable Affiliates) in the ordinary course of its business, on a consistent basis; provided, however, that for Customers in the United States, the calculation of the Net Component Price shall not take into account prompt-pay discounts. For clarity, except as otherwise expressly provided in this definition, the Net Component Price shall take account of any customer-specific discounts or rebates provided to such Customer. Notwithstanding any of the foregoing, in the case of determining the Net Component Prices of the TMC278 Product and Truvada with respect to any given country, (a) the Parties may elect by mutual written agreement to include or exclude from the calculation of the Net Component Price any deductions, payments or rebates given to Customers in such country and (b) the Parties shall coordinate in good faith to harmonize their respective practices in the calculation of Net Component Prices in such country, such that each Party’s method of calculating the Net Component Price for its respective products includes or excludes the same categories or types of deductions as the other Party’s method.

Agreement. To the extent that products or services covered by the Manufacturing Fee are expected to be sourced from multiple vendors in a given year, the estimated Manufacturing Fee for such year shall, to that extent, represent a weighted average standard based on expected sourcing.

Any amount invoiced to Tibotec pursuant to Section 10.2 of the Agreement during the period from January 1 through February 15 of a Calendar Year for its portion of any Manufacturing Fees shall be recalculated promptly based on Tibotec’s current Working Percentage for such Calendar Year (rather than the prior Calendar Year’s Working Percentage) and the Parties shall make reconciling payments or issue credit notes, as appropriate, promptly following such recalculation (or as otherwise agreed by the Parties in writing) to effect the result of such modified calculations.

No later than the January 31 after the end of each Calendar Year, Gilead shall calculate the actual Manufacturing Fee for each Manufacturing Stage with respect to the Calendar Year then-ended and shall multiply the actual Manufacturing Fee for each Manufacturing Stage for such Calendar Year for the Territory by the number of Units of Territory Combination Product for which Tibotec’s portion of the Manufacturing Fee with respect to such Manufacturing Stage was invoiced to Tibotec during such Calendar Year pursuant to the Agreement (with respect to a given Manufacturing Stage, the “Actual Manufacturing Fee”). Gilead shall add together (a) the Actual Manufacturing Fee for each of the two Manufacturing Stages and (b) the Additional Manufacturing Fee for such Calendar Year (such aggregate amount, the “Annual Manufacturing Fee” for such Calendar Year), which amount shall be used for the purpose of making any year-end adjustments required pursuant to Section 10.3 of the Agreement.

For Immediate Release

GILEAD SCIENCES ANNOUNCES AGREEMENT WITH TIBOTEC PHARMACEUTICALS TO DEVELOP AND COMMERCIALIZE NEW FIXED-DOSE COMBINATION OF TRUVADA^® AND TMC278

— Product Would Represent Second Truvada-Based Complete Fixed-Dose Regimen —

Foster City, CA, July 16, 2009 – Gilead Sciences, Inc. (Nasdaq: GILD) today announced that it has entered into a license and collaboration agreement with Tibotec Pharmaceuticals for the development and commercialization of a new once-daily fixed-dose antiretroviral regimen containing Gilead’s Truvada^® (emtricitabine and tenofovir disoproxil fumarate) and Tibotec’s investigational non-nucleoside reverse transcriptase inhibitor (NNRTI) TMC278 (rilpivirine hydrochloride, 25 mg) for treatment-naïve HIV-infected individuals. Fixed-dose combinations contain multiple medicines formulated into one tablet and help to simplify HIV therapy.

“Gilead and Tibotec share a strong focus on bringing safe and effective treatment options to people living with HIV/AIDS,” said John C. Martin, PhD, Chairman and Chief Executive Officer, Gilead Sciences. “Fixed-dose regimens have become the standard of care as HIV treatment has evolved toward more simplified regimens for patients. We are very pleased to collaborate with Tibotec and look forward to advancing this new fixed-dose product.”

Subject to regulatory approval, Gilead will assume the lead role in the manufacturing, registration, distribution and commercialization of the fixed-dose combination of Truvada and rilpivirine worldwide, excluding the developing world and Japan. Tibotec will be responsible for the commercialization of rilpivirine as a stand-alone product and will hold rights to co-promote the fixed-dose combination in these territories. The companies will also work towards an agreement to make the fixed-dose combination of Truvada and rilpivirine available in the developing world.

If approved, the new product would become the second complete antiretroviral treatment regimen for HIV available in a single tablet taken once daily. The first and only such therapy available today, Atripla^® (efavirenz 600 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg), was approved

Annex S-1 Page 1

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

by the U.S. Food and Drug Administration (FDA) in 2006. Both Atripla and the new fixed-dose combination contain a nucleoside reverse transcriptase inhibitor (NRTI) backbone of Truvada.

Current HIV treatment guidelines issued by the U.S. Department of Health and Human Services list emtricitabine and tenofovir (the components of Truvada) in combination with an NNRTI or a protease inhibitor as a preferred regimen for patients initiating therapy. Tibotec is currently studying the combination of Truvada and rilpivirine in Phase III clinical trials.

Two Phase III trials for rilpivirine are currently being conducted in the United States, Canada, Africa, Asia, Europe and South America. As an investigational agent, the safety and efficacy of rilpivirine, in combination with other antiretroviral agents, has not yet been established in humans.

“A simplified regimen may help improve patient adherence and decrease overall pill burden,” said Roger Pomerantz, MD, President Tibotec R&D. “We are very pleased to collaborate with Gilead, one of the leading companies in the fight against HIV/AIDS, and look forward to advancing this new fixed-dose product in addition to TMC278 as a single agent.”

This agreement represents the first fixed dose combination product collaboration for Tibotec and, when approved, it would become the first complete once-daily antiretroviral treatment regimen for HIV to include an antiretroviral from Tibotec. Tibotec is currently studying the combination of Truvada and TMC278 in its Phase III program; the two ongoing pivotal clinical trials, TMC278-C209 and TMC278-C215 are fully recruited having enrolled over 1,300 treatment-naïve adult patients with HIV-1. Current HIV treatment guidelines issued by the U.S. Department of Health and Human Services list emtricitabine and tenofovir (the components of Truvada) in combination with a non-nucleoside reverse transcriptase inhibitor or a protease inhibitor as a preferred regimen for patients initiating therapy.

Tibotec will remain uniquely responsible for the commercialization of TMC278 as a single product and additionally will have the right to promote the fixed-dose combination product to healthcare professionals in all countries except Japan and the access countries. Gilead will assume the lead role in manufacturing, registration and, subject to regulatory approval, commercialization of the fixed-dose combination of TMC278 and Truvada throughout the territory.

Tibotec and Gilead are committed to working together to make the fixed-dose combination of TMC278 and Truvada available in the developing world and will work towards a separate agreement for these countries.

Notwithstanding anything in this Agreement to the contrary, if any modification, amendment, renewal or extension of or to any Guaranteed Agreement is made, without Guarantor’s written consent, by any party other than Guarantor and its Affiliates, Guarantor shall have no liability with respect to, and the Guaranteed Obligations shall not include, any obligation arising out of such modification, amendment, renewal or extension, to the

UNDER 17 C.F.R. §§ 200.80 (b)(4) AND 230.406

extent that such obligation would not exist in the absence of such modification, amendment, renewal or extension.

1.4 Waiver. Guarantor hereby waives (a) notice of (i) acceptance hereof, (ii) any action taken or omitted in reliance hereon, (iii) any default with respect to any Guaranteed Obligation and (b) any other notice of any kind not provided for in this Agreement or in any Guaranteed Agreement. Guarantor also waives any requirement that the Guaranteed Party proceed first against the Gilead Entities under any Guaranteed Agreement with respect to any Guaranteed Obligation before proceeding hereunder; provided, however, that notwithstanding anything in this Agreement to the contrary, if any dispute between the Guaranteed Party and any Gilead Entity relating to a Guaranteed Obligation is subject to arbitration under Section 20.7 of the Collaboration Agreement (or any other dispute resolution procedure set forth in the applicable Guaranteed Agreement) or is a Patent Matter, the Guaranteed Party may not proceed against Guarantor under this Agreement unless and until the procedures set forth in Section 20.7 of the Collaboration Agreement (or any other dispute resolution procedure set forth in the applicable Guaranteed Agreement) have been complied with in full or, in the case of a Guaranteed Obligation that is a Patent Matter, it has been determined by the applicable court pursuant to Section 20.8(b) to be payable by the Gilead Entity. Nothing contained in this Agreement shall affect the right of Guarantor to assert (x) any claim it may have against the Guaranteed Party (or its successors or assigns) in a separate action or proceeding or (y) any defense, set off or counterclaim that any Gilead Entity may have against the Guaranteed Party (or its successors or assigns) arising out of any Guaranteed Agreement or any transaction contemplated thereby.

1.5 Reinstatement. Guarantor agrees that, with respect to any Guaranteed Obligation, if at any time following the termination of this Agreement all or any part of any payment of the Guaranteed Obligations is rescinded or required to be returned by the Guaranteed Party to any Person for any reason whatsoever (including, without limitation, the insolvency, bankruptcy, or reorganization of any Gilead Entity) this Agreement shall be reinstated with respect to such payment so rescinded or returned as though such payment had never been received by the Guaranteed Party.

specific performance and general principles of equity, whether enforceability is considered in a proceeding at law or in equity.

2.2 Assignability; Binding Effect. Guarantor and the Guaranteed Party each may assign this Agreement only [*]. Any assignment of this Agreement in violation of this Section 2.2 shall be null and void and of no force and effect. This Agreement shall be binding upon, inure to the benefit of, and be enforceable by the successors and permitted assigns of Guarantor and the Guaranteed Party.

2.5 Construction. The headings and subheadings of this Agreement are inserted for convenience of reference only and shall not affect the interpretation of this Agreement.

2.6 Entire Agreement; Amendments. This Agreement constitutes the entire agreement of the parties hereto with respect to the subject matter hereof. This Agreement may be amended only in a writing signed by Guarantor and the Guaranteed Party and any waiver of rights hereunder must be set forth in writing signed by the party against whom the waiver is to be effective.

2.7 Third Party Rights.

2.10 Notice. The notice provisions set forth in Section 20.2 of the Collaboration Agreement shall likewise apply to Guarantor and the Guaranteed Party with respect to this Agreement; provided, however, that notice shall be provided to Guarantor at the following address (or to such other address as may be specified by notice to the Guaranteed Party from time to time by Guarantor):

2.11 Subrogation. Guarantor will not exercise any rights which it may have acquired against any Gilead Entity by way of subrogation, by any payment made hereunder or otherwise, or accept any payment on account of such subrogation rights, unless and until all of the Guaranteed Obligations of such Gilead Entity for which payment is then due have been fully satisfied.

2.12 [*] Guarantee Agreement. Notwithstanding anything in this Agreement to the contrary, (a) any continuing failure, for any reason whatsoever, by [*] to abide by the terms of that certain Guarantee Agreement by and between [*], Guarantor and Gilead Sub, dated as of the date hereof (as it may be amended from time to time, the “[*] Guarantee Agreement”) shall (so
