for the purpose set forth in clause (i), (ii) or (iii) above, as the case may be. Clause (iii) of the immediately preceding sentence shall not require any Party to provide such
data, documentation or records in the event that the Parties’ interests in such matter are or may be adverse in any material respect, in which case Applicable Law, including discovery rules and procedures, shall apply. Each such request shall
be made in writing and shall state the reason(s) therefor (each a “Development Record Request”). The Party from which such records, documentation or data are requested shall have the right to raise reasonable objections in writing
in response to such Development Record Request, including based on such Party’s interests in protecting from disclosure trade secrets or other competitive business information. Upon any such objection being asserted, the Parties shall promptly
confer in an attempt to address each Party’s concerns and reach a resolution with respect to the matter, and in the event that the Parties are unable to agree upon a mutually agreeable resolution, either Party shall have the right to refer the
matter to the Executives. In the event that any such dispute is ultimately referred by a Party to arbitration pursuant to Section 2.4(c), the arbitrator(s) shall determine as a threshold matter whether and to what extent one or more criteria
set forth in clauses (i), (ii) or (iii) above have been satisfied by the requesting Party, and, if so, shall make a determination with respect to whether and to what extent the disclosure of such information shall be required by balancing,
on the one hand, the requesting Party’s need to obtain such records, documentation or data, and on the other hand, the objecting Party’s interests in protecting such records, documentation and data from disclosure. In making such
determination, the arbitrator(s) (A) shall confine their consideration to the facts and arguments set forth in the Development Record Request and the other Party’s written response thereto, and (B) shall have the right to require the
receiving Party to abide by terms and conditions for the handling, use and non-disclosure (either within such Party’s organization or to Third Parties) of such information as may be reasonable under the circumstances.

present, as the case may be. If requested by the reviewing Party, the publishing Party shall provide the Clinical Data supporting such proposed publication or presentation within three (3) Business Days of the later of such request and the
reviewing Party’s receipt of the proposed publication or presentation. Written copies of each such proposed publication or presentation required to be provided for review shall be provided to the other Party’s Alliance Manager no later
than twenty (20) days before submission for publication or presentation, except that (i) in the case of an abstract, a copy of the abstract shall be provided as soon as reasonably practicable in advance of the submission of such abstract

provided to such Regulatory Authority in order for the Selling Party to obtain an Approval for the Combination Product in the Field in such country. 
 4.2 Registration Plan. 
 (a) Creation. Within one hundred eighty
(180) days after the Effective Date, the Parties shall commence discussion of, and within one (1) year after the Effective Date, shall establish, an initial plan of activities for obtaining and maintaining Approvals for the Combination

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).

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.

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.

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

 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:

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:

 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).

 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

(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

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

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).

 (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.

 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.,

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.

 (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).

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

 (c) Price Approval Countries. 
 (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

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,

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). 
 (C) Medicaid. 
 (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

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.

 (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

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.

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

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,

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.

which Gilead is the Selling Party in its reasonable discretion on account of product expiry (or short remaining shelf-life, as applicable), or such Combination Product is otherwise returned by a Customer (and such Customer is entitled to a credit in
connection with such return pursuant to Gilead’s (or its Affiliate’s) applicable standard return policy (published and in effect immediately prior to such return)) to Gilead (or its applicable Affiliate), and cannot be resold (any such

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

Year as set forth in Annex Q. “Hedge-able Currency” means any of the following: [*].

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.

this Section 10, and each Party shall be responsible for any taxes (including any such taxes imposed by way of withholding) in the nature of income or franchise taxes or based on or measured by gross or net income imposed with respect to its

 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

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. 
 SECTION 11 
 FINANCIAL CALCULATIONS AND ADJUSTMENTS 
 11.1 Calculations. Any
obligation of a Party hereunder to make any calculation or to provide the results of such calculation, which calculation requires any information that the other Party is obligated to provide hereunder, shall be subject to receipt of such information
from such other Party. In the event that delivery of any such information to the Party performing such calculation is delayed, the deadline for performing such calculation and providing the results of such calculation shall be extended for a period
of time corresponding to such delay. 
 11.2 Working Percentages. The Working Percentages for each Calendar Year shall be
determined as set forth in Annex H. 
 11.3 Actual Percentages. Gilead shall calculate the Actual Percentages with
respect to each Calendar Year in accordance with Annex I. Gilead shall use reasonable efforts to provide such percentages to Tibotec no later than January 31 after the end of such Calendar Year. 
 11.4 Establishment of API Replacement Costs. For each Calendar Year, on or before November 15 prior to such Calendar Year,
Tibotec shall notify Gilead in writing of the TMC278 Replacement Cost for such Calendar Year and Gilead shall notify Tibotec in writing of the TDF Replacement Cost and the FTC Replacement Cost for such Calendar Year. Tibotec shall calculate the
TMC278 Replacement Cost and Gilead shall calculate the TDF Replacement Cost and FTC Replacement Cost, in each case, for each such Calendar Year (and any adjustments thereto) in accordance with Annex O based on the applicable Party’s good faith
estimate of the cost of replacing the applicable API during such Calendar Year.

 11.5 Establishment/Adjustment of the Supply Prices. Subject to the other terms
and conditions of this Agreement, the TMC278 Supply Agreement shall provide that, with respect to any quantity of Supplied TMC278, Tibotec shall issue, and Gilead shall pay, a Pre-Conversion Invoice and a Post-Conversion Invoice in accordance with
the terms and procedures set forth on Annexes M and N such that Gilead pays to Tibotec the Post-Conversion Supply Price for the Supplied TMC278. On a monthly basis, no later than the tenth (10th) Business Day after the end of each month, Gilead
shall calculate the Post-Conversion Supply Price for Supplied TMC278 corresponding to Combination Product for which Triggering Sales occurred in such month in accordance with Annex N, and shall provide such Post-Conversion Supply Price to Tibotec.
All Pre-Conversion Supply Prices and Post-Conversion Supply Prices shall be calculated in U.S. Dollars. 
 11.6
[*]. For each Calendar Quarter following the [*] with respect to a given country in the Territory, this Section 11.6 shall apply with respect to such country as follows: 
 (a) the Specified Percentage with respect to the Territory Combination Product sold in such country shall be modified to [*] with
respect to such country; or 
 (b) the Specified Percentage with respect to the Territory Combination Product sold in such
country shall be modified to [*];

 11.7 Payment Terms and Related Matters. 
 (a) All TMC278 Invoices shall be
issued and paid in U.S. Dollars. 
 (b) Within ten (10) Business Days after the end of each month, with respect to any
Triggering Sales of Combination Product by Gilead in the Territory occurring in such month, Gilead shall notify Tibotec of the due date of any TMC278 Invoice (or portion thereof) for which a due date is established due to any such Triggering Sale,
which due date Gilead shall calculate in accordance with Annex M. Such due date shall constitute the due date for payment of the applicable TMC278 Invoice under the TMC278 Supply Agreement. For clarity, (i) this Section 11.7(b) is intended
to apply to TMC278 Invoices for Combination Product sold to all Customers, including Third Party Distributors and (ii) the due date calculated in accordance with Annex M with respect to any Triggering Sale shall apply to both the portion of the
Pre-Conversion Invoice and the portion of the Post-Conversion Invoice with respect to a given quantity of Supplied TMC278 that corresponds (based on the Estimated Yield Rate) to such Triggering Sale.

 (c) The Parties acknowledge and agree that Pre-Conversion Invoices shall become due on a
first-in, first-out basis (as set forth in Annex M) and a portion of a Pre-Conversion Invoice may be due earlier than the remainder of such invoice. For clarity, this Section 11.7(c) is intended to apply to Pre-Conversion Invoices corresponding
to Combination Product sold to all Customers, including Third Party Distributors. 
 (d) In the case that the Selling Party
determines, consistent with GAAP and its ordinary course of business, that any amounts due from a Third Party with respect to any Triggering Sale of the Territory Combination Product with respect to any country for which it is the Selling Party
constitute bad debt such that a write-off of such amounts will occur, then such amounts, to the extent subject to a write-off, shall be treated as follows: [*], in the case of Gilead as the Selling Party. Further, if the Selling Party
subsequently collects any amounts previously written off as bad debt (pursuant to the preceding sentence) from a Third Party with respect to any quantity of Combination Product, the adjustment made pursuant to the immediately preceding sentence
shall be reversed with respect to such quantity of Combination Product. 
 (e) If Tibotec becomes the Selling Party in any
country in the Territory, the Parties shall amend this Agreement to address the matters described in this Section 11.7 as they apply to invoices for the Combination Product issued by Gilead or its applicable Affiliate pursuant to any Tibotec
Distributor Agreement (to the extent that such matters are not addressed in any such Tibotec Distributor Agreement).

or in reporting Manufacturing Fees or other information hereunder (other than inaccurate pricing or discount information), which inaccurate information caused an underpayment by the Audited Party or overpayment by the Auditing Party hereunder or
under any Ancillary Agreement with respect to a given Calendar Year of [*] or more. Except as provided in the foregoing sentence or as otherwise agreed by the Parties in writing, (i) in the case of an audit pursuant to

or determination. Each Party shall also notify the other (i) in the event of the issuance by such Party of an FDA field alert or similar alert or foreign equivalent thereof (in which case the Party issuing such field alert shall notify the
other Party at the same time as the applicable governmental agency or authority) with respect to the Combination Product or any of such Party’s Single Agent Product(s) (or, in the case of Tibotec, any Other TMC278 Product, if the reason for
such field alert is reasonably likely to affect the Combination Product) or Double Agent Product, and (ii) within twenty-four (24) hours of such Party’s receipt of any communication from any governmental agency or authority regarding
a potential recall or market withdrawal of the Combination Product or any of such Party’s respective Single Agent Product(s) (or, in the case of Tibotec, any Other TMC278 Product, if the reason for such communication is reasonably likely to

 (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).

limitation of Section 13.2(b), any withdrawal or recall with respect to the Combination Product in any country in the Territory required or agreed upon by the Parties pursuant to this Section 13.2 shall be conducted by the Selling Party
with respect to such country (or in the case of a country in which a Third Party Distributor is the distributor in such country, the Selling Party shall cause the Third Party Distributor to conduct such product recall or withdrawal) with reasonable
cooperation from the other Party, regardless of whether the other Party requested such withdrawal or recall. 
 (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): [*].

 (b) Tibotec Patents. Tibotec, through patent attorneys or agents of its choice, shall have the first right, at its sole cost and
expense, to prepare, file, prosecute and maintain the Tibotec Patents, including Patents claiming or covering the Tibotec-Owned Collaboration Inventions, anywhere in the world in the name of Tibotec. If Tibotec elects not (i) to pursue or
continue the filing, prosecution (including any interferences, reissue proceedings and re-examinations) or maintenance of a Tibotec Patent claiming or covering the Manufacture, sale, use or formulation of the Combination Product (other than the
Manufacture of TMC278) (a “Combination Product-Related Tibotec Patent”) in the Field in the Territory, or (ii) to take any other action with respect to a Combination Product-Related Tibotec Patent in the Field in the Territory
that is necessary or useful to establish, preserve or extend rights thereto, then in each such case Tibotec shall so notify Gilead in writing not less than two (2) months before any deadlines by which an action must be taken to establish or
preserve any such rights in such Tibotec Patent in the Field in the Territory. Upon receipt of any such notice, Gilead shall have the right, but not the obligation, at its sole cost and expense, through counsel of its choosing, to pursue the filing
or registration, or support the continued prosecution (including any interferences, reissue proceedings and re-examinations) or maintenance, of such Tibotec Patent. If Gilead elects to pursue such filing or registration, as the case may be, or
continue such support, then Gilead shall notify Tibotec of such election and Tibotec shall, and shall cause its Affiliates to, reasonably cooperate with Gilead in this regard. Gilead shall have sole discretion to determine which Tibotec Patents, if
any, shall be listed in the “Orange Book” in the U.S., or any analogous or similar listing in any other country in the Territory, with respect to the Combination

Product. Without limitation of Section 14.1(e), Gilead shall, and shall cause its Affiliates and their respective employees and agents to, reasonably cooperate, by the execution of documents
and otherwise, to vest ownership of the Tibotec-Owned Collaboration Inventions in Tibotec. 
 (c) Joint Patents.

 (i) Relating to the Combination Product. Gilead, through patent attorneys or agents of its choice, shall have the
first right, but not obligation, at its sole expense, to prepare and file Patent applications claiming the Joint Know-How to the extent that such Joint Know-How is related to the Combination Product and to obtain, prosecute, and maintain Joint
Patents to the extent related to the Combination Product throughout the Territory. Tibotec shall have the right to request that Gilead obtain, prosecute and maintain a Joint Patent related to the Combination Product in a particular country. If
Gilead declines in writing to do so, or otherwise fails to initiate any such requested action with respect to the Joint Patent within sixty (60) days after receiving a request (and thereafter diligently pursue such action), Tibotec shall have
the right, but not the obligation, at its sole cost and expense, through counsel of its choosing, to pursue such action with respect to such Joint Patent. Gilead and Tibotec shall, and shall cause their respective Affiliates, as applicable, to
assist and cooperate with one another in obtaining, prosecuting and maintaining the Joint Patents and the reasonable costs and expenses of such assistance and cooperation shall be allocated as costs and expenses are otherwise allocated under this
clause (i). 
 (ii) Other Joint Patents. In the event that either Party desires to prepare and have filed any Patent
application in the Territory claiming the Joint Know-How to the extent that such Joint Know-How is not related to the Combination Product, such Party shall propose such filing to the other Party and the Parties shall discuss and agree in writing on
which Party shall take responsibility for preparing and filing the Patent application and the allocation as between the Parties of costs and expenses related to such Joint Patent application. In the event that the Parties fail to reach agreement
that such Patent application should be filed, neither Party may file or cause to be filed such patent application. In the event that the Parties agree that a patent application for a Joint Patent claiming or covering a Joint Invention that is not
related to the Combination Product should be filed, the Party designated to lead such application process (the “Lead Patent Party”) shall have the sole right and obligation, in consultation with the other Party, to prepare, file,
prosecute, maintain and take any other actions as directed by the Parties with respect to such Joint Patents in the name of both Parties in such countries as the Parties shall direct, and the costs and expenses with respect thereto shall be shared
by the Parties as agreed pursuant to this Section 14.2(c)(ii). The Lead Patent Party shall keep the other Party advised of the status of Joint Patent filings pursuant to this Section 14.2(c)(ii) and upon request of the other Party shall
provide copies of any official correspondence or other documentation with respect to official actions and submissions relating to the prosecution or maintenance of such Joint Patents. For the avoidance of doubt, the Lead Patent Party may elect to
use outside patent counsel for the filing, prosecution and maintenance of the Joint Patents subject to the approval of the non-Lead Patent Party. The non-Lead Patent Party may engage outside patent counsel, at its expense, to

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

 
review any filings to be made with respect to any Joint Patent. The non-Lead Patent Party shall, and shall cause its Affiliates to, assist and cooperate with the Lead Patent Party in filing,
prosecuting and maintaining the Joint Patents to the extent not related to the Combination Product. Costs and expenses with respect to such assistance shall be shared by the Parties as agreed pursuant to this Section 14.2(c)(ii). 
 (iii) Cooperation. Without limitation of Section 14.1(e), each Party shall, and shall cause its Affiliates and their respective
employees and agents to, reasonably cooperate, by the execution of documents and otherwise, to vest co-ownership of such Joint Patents in one another. 
 (iv) Orange Book. Gilead shall have the sole discretion to determine which Joint Patents, if any, shall be listed in the “Orange Book” in the U.S., or any analogous or similar listing in
any other country in the Territory, with respect to the Combination Product. 
 (d) Extensions. Each Party may file and
prosecute to obtain extensions of the Tibotec Patents (in the case of Tibotec) or the Gilead Patents (in the case of Gilead) in any country in which such extensions are available, each in its sole discretion. 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

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

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

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. 
 14.6 Trademarks. 
 (a) Gilead Licensed Trademarks. Gilead shall have the sole right, at its sole cost and expense, to search, clear, file, register,
prosecute, maintain and enforce the Gilead Licensed Trademarks in the Territory. Gilead shall have the sole right and option, at its sole cost and expense, to respond to any infringement with respect to any Gilead Licensed Trademark in the Territory
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 prosecute, maintain or enforce Gilead Licensed Trademarks in the Territory or take action to
respond to any such infringement in the Territory. 
 (b) Tibotec Licensed Trademarks. Tibotec shall have the sole right,
at its sole cost and expense, to search, clear, file, register, prosecute, maintain and enforce the Tibotec Licensed Trademarks in the Territory. Tibotec shall have the sole right and option, at its sole cost and expense, to respond to any
infringement with respect to any Tibotec Licensed Trademark in the Territory by appropriate steps, including by filing an infringement suit or taking other similar action. Tibotec shall also have the sole right and option not to prosecute, maintain
or enforce Tibotec Licensed Trademarks in the Territory or take action to respond to any such infringement in the Territory.

their respective Affiliates, Gilead (or its designee) shall own all right, title and interest in and to the Combination Product Trademarks. 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). 
 (ii) Infringement. If Tibotec has a reasonable basis to believe that a Third Party is engaging in commercially significant infringement of any Combination Product Trademark in any Tibotec Country, Tibotec shall notify Gilead in
writing and provide it with any evidence of such infringement that is reasonably available. As between the Parties, Gilead or its designee shall have the sole right and option, at its sole expense, to respond to any infringement or potential
infringement with respect to any Combination Product Trademark 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. Tibotec shall provide reasonable assistance to Gilead or such designee with respect to any enforcement activities with respect to the Combination Product Trademarks pursuant to this Section 14.6(c)(ii), 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 Gilead or its designee to maintain the action. Any amounts recovered pursuant to
this Section 14.6(c)(ii), whether by settlement or judgment, shall be allocated between the Parties in a manner analogous to the allocation set forth in Section 14.4(f). 
 SECTION 15

 15.1 Treatment of Confidential Information. Except as provided in this Section 15, during the term of this Agreement and for
five (5) years thereafter, each Party (the “Receiving Party”) (a) shall hold in confidence and shall not publish or otherwise disclose, directly or indirectly, to any Third Party any Confidential Information of the other
Party or its Affiliates (collectively, the “Disclosing Party”), (b) shall not directly or indirectly use Confidential Information of a Disclosing Party for any purpose other than performance of its obligations or exercise of
its rights under this Agreement or any Ancillary Agreement, and (c) shall use the same level of effort to maintain the confidentiality of Confidential Information of a Disclosing Party as it uses for its own confidential or proprietary

 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. 
 (b) Exclusions.
Notwithstanding the foregoing, any information of the Disclosing Party shall not be deemed Confidential Information with respect to the Receiving Party if it: 
 (i) was already known to the Receiving Party or any of its Affiliates, other than to the extent and for so long as the Receiving Party (or its Affiliate) is under an obligation of confidentiality or
non-use with respect to such information, at the time of disclosure to such Receiving Party or its Affiliate; 
 (ii) was
generally available or known, or was otherwise part of the public domain, at the time of disclosure to such Receiving Party or its Affiliate;

after its disclosure to such Receiving Party or its Affiliate; 
 (iv) was received by such Receiving Party or any of its
Affiliates from a Third Party that, to the knowledge of the Receiving Party, had no obligation to the Disclosing Party not to make such disclosure; or 
 (v) was independently discovered or developed by such Receiving Party or any of its Affiliates, as evidenced by their written records, without the use of Confidential Information of the Disclosing Party.

 Specific aspects or details of Confidential Information shall not be deemed to be within the public domain or in the possession of a Party or
its Affiliate merely because the Confidential Information is embraced by more general information in the public domain or in the possession of such Party or its Affiliate. 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

 15.4 Notification. Each Party shall notify the other Party immediately, and cooperate with the other Party as the other Party may
reasonably request, upon the first Party’s discovery of any loss or compromise of the other Party’s Confidential Information. 
 15.5 Data Privacy. Without limitation of its other obligations under this Section 15, each Party shall, and shall cause each of its Affiliates to, comply with Applicable Law, including the
applicable national laws implementing the European Union Directive 95/46/EC on the protection of individuals with regard to the processing of personal data and on the free movement of such data of 24 October 1995, with respect to the
collection, use, transfer, storage, deletion, processing (both by computer and manually), combination or other use of subject or other personal data as contemplated by applicable data protection or privacy laws of all data relating to any Person
about whom or which data may be collected, retained or exchanged pursuant to this Agreement or any Ancillary Agreement. Without limitation of the foregoing, each Party shall, and shall cause each of its Affiliates to, ensure that it takes any
technical and organizational measures required by Applicable Law to protect any such data against accidental or unlawful destruction, loss, damage, alteration, disclosure, access or data processing and against all other unauthorized disclosure,
access or forms of data processing. 
 15.6 Remedies. Each Party agrees that the unauthorized use or disclosure of any
material Confidential Information by the Receiving Party in violation of this Agreement may cause severe and irreparable damage to the Disclosing Party, for which money damages may represent an insufficient remedy. In the event of any violation of
this Section 15, notwithstanding anything in this Agreement to the contrary, the Disclosing Party shall be authorized and entitled to seek from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, with
respect to such violation as well as any other relief permitted by Applicable Law.

Double Agent Product, shall be subject to prior approval by Gilead, such approval not to be unreasonably withheld and (b) in the case of Gilead as the announcing Party, any proposed public announcement that refers to the safety, efficacy or
other characteristics of the Territory Combination Product or Tibotec’s Single Agent Product, shall be subject to prior approval by Tibotec, such approval not to be unreasonably withheld. Further, if any proposed public announcement by either
Party that relates to the Exploitation of the Territory Combination Product uses any name or any Trademark of the other Party or its Affiliates (other than a Gilead Licensed Trademark or a Tibotec Licensed Trademark used in connection with Territory
Combination Product), such public announcement shall be subject to prior approval of such other Party, except to the extent such announcement is required by Applicable Law. If the non-announcing Party with respect to any public announcement provided
by the announcing Party for review under this Section 16.2 desires to provide comments or, if applicable, indicate whether the applicable public announcement is approved, it shall do so as soon as reasonably practicable but in any event within
three (3) Business Days after receiving the proposed announcement for review. Subject to Section 16.3, neither Party shall be required to have the other Party review or, if applicable, approve the public disclosure of any information that
has already been publicly disclosed by either Party in accordance with Section 3.6, Section 15.2 or this Section 16.2. In the event of a legally required press release or other public announcement or disclosure, the Party (or its
Affiliate) desiring to make such announcement shall provide the other Party with a copy of the proposed text with as much notice as practicable (which shall, to the extent practicable under the circumstances, be no less than three (3) Business
Days prior to the proposed disclosure), the other Party shall respond with its comments (if any) as promptly as practicable (but no less than one (1) Business Day prior to the proposed disclosure), and the proposing Party shall take into due
consideration any and all reasonable comments that the other Party may provide in a timely manner; provided, however, that, notwithstanding the foregoing, if a Party determines that it or any of its Affiliates must make a legally required disclosure
under Regulation FD, 17 CFR § 243.100, et seq., as amended from time to time, or other similar Applicable Law, then it or its Affiliate, as applicable, shall have the right to make such disclosure at such time as is necessary to
comply with Regulation FD or such other Applicable Law, and shall provide the other Party as much notice and opportunity for review and comment as is practicable in the circumstances. 
 16.3 Use of Names. Except as otherwise permitted expressly herein or in any Ancillary Agreement or other written agreement between
the Parties (or their respective Affiliates), neither Party shall mention or otherwise use any Trademark, including any name, insignia, symbol, trade name or logotype of the other Party (or any abbreviation or adaptation thereof) in any publication,
press release, promotional material or other form of publicity without the prior written approval of such other Party in each instance. The restrictions imposed by this Section 16.3 shall not prohibit any Party from making any disclosure
identifying another Party or

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

 (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.

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

term of this Agreement, without the prior written consent of Tibotec (i) Gilead will not import, sell or offer to sell, and will cause its Affiliates not to import, sell or offer to sell, and (ii) Gilead 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 [*];

obligation to supply Supplied TMC278 under the TMC278 Supply Agreement.

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

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

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

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).

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

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

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

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

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.

 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

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

 
Material Breach has been cured, this Agreement shall not be terminated if the alleged cure has effectively remedied the harm to the Non-Breaching Party caused by the Material Breach. 

19.5 Voluntary Termination. 
 (a) In the event of a Program Failure, either Party may terminate this Agreement in its entirety at any time prior to Approval of the Combination Product in the Field by the FDA or the grant of the
marketing authorization of the Combination Product in the Field by the European Commission, whichever occurs first, by written notice to the other Party. A “Program Failure” shall mean the failure of either of the phase III Ongoing
TMC278 Studies to meet their primary clinical endpoints. Such termination shall be effective as of the date of such notice. 
 (b) If both of the following circumstances have occurred: (i) as of the third anniversary of the first Approval of the TMC278 Product in the Field in the United States (which date shall be extended for the period of time that Gilead
agrees in writing to exert Commercially Reasonable Efforts to perform Clinical Trials or other studies (other than bioequivalence studies) that have become necessary to obtain Approval from the FDA for the Combination Product in the Field), Approval
of the Combination Product in the Field has not been granted by the FDA and (ii) as of the third anniversary of the first marketing authorization of the TMC278 Product in the Field by the European Commission (which date shall be extended for
the period of time that Gilead agrees in writing to exert Commercially Reasonable Efforts to perform Clinical Trials or other studies (other than bioequivalence studies) that have become necessary to obtain marketing authorization from the European
Commission for the Combination Product in the Field), marketing authorization of the Combination Product in the Field has not been granted by the European Commission, then Tibotec may terminate this Agreement in its entirety by written notice to
Gilead, provided that Tibotec exercises such termination right prior to the first Approval of the Combination Product in the Field in the United States or the first marketing authorization of the Combination Product in the Field by the European
Commission. 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.

 (d) On or after the expiration of the last to expire of the Viread Patents (as defined
below) in the United States, Gilead may terminate this Agreement with respect to the United States and Canada by written notice to Tibotec. On and after the expiration of the last to expire of the Viread Patents in the first country in the European
Union in which the Viread Patents expire, Gilead may terminate this Agreement with respect to all countries other than the United States and Canada by written notice to Tibotec. Any termination pursuant to this clause (d) shall be effective as
of the later of (i) the last day of the second (2nd) Calendar Quarter after the Calendar Quarter in which such notice is delivered to the other Party and (ii) such expiration date. A “Viread Patent” shall mean a
Patent in the applicable country that contains at least one claim that (A) covers TDF or use (excluding any use in combination claim) of TDF in the Field, and (B) has not been determined to be invalid or unenforceable by a court in the
applicable jurisdiction. 
 (e) On or after the expiration of the last to expire of the TMC278 Patents (as defined below) in the
United States, Tibotec may terminate this Agreement with respect to the United States and Canada by written notice to Gilead. On or after the expiration of the last to expire of the TMC278 Patents in the first country in the European Union in which
the TMC278 Patents expire, Tibotec may terminate this Agreement with respect to all countries other than the United States and Canada by written notice to Gilead. Any termination pursuant to this clause (e) shall be effective as of the later of
(i) the last day of the second (2nd) Calendar Quarter after the Calendar Quarter in which such notice is delivered to Gilead and (ii) such expiration date. A “TMC278 Patent” shall mean a Patent in the
applicable country that contains at least one claim that (A) covers TMC278 or use (excluding any use in combination claim) of TMC278 in the Field, and (B) has not been determined to be invalid or unenforceable by a court in the applicable
jurisdiction and (C) with respect to the European Union is either issued or a patent application that is pending (and has been pending for [*] and not abandoned. 
 19.6 Consequences of Termination. 
 (a) Termination Prior to Commercialization. Upon termination of this Agreement pursuant to Section 19.2, 19.5(a), 19.5(b) or 19.5(c), the provisions of this Section 19.6(a) shall apply
(with respect to the applicable country, in the case of a country-specific termination). The license grants in Section 9 (other than those license grants that survive as described in Section 19.7(b)) to a Party shall survive only to the
extent necessary to enable such Party (or its Affiliates) to perform any obligations of such Party (or its Affiliates) that survive the termination of this Agreement or any Ancillary Agreement or as otherwise provided in Section 19.7(b). No
later than thirty (30) days after the date of such termination, each Party shall make arrangements for, at the election of the other Party, either the return or disposal of any Confidential Information of the other Party, whether such
Confidential Information is in tangible or intangible form (except for one (1) copy which may be retained solely for archival purposes); provided, however, that the foregoing shall not apply with respect to any such Confidential
Information (i) to the extent that this Agreement or any other binding agreement between the Parties (or their respective Affiliates) expressly provides that the returning Party retains the right

to use such Confidential Information (e.g., in the case of a surviving license) following such termination or (ii) in the case of a Region-specific or country-specific termination, to
the extent that such Confidential Information is relevant to any other Region or country as to which termination has not yet occurred. Solely in the case of a termination of this Agreement by Gilead pursuant to Section 19.5(a), in the event
that Gilead has paid less than [*] pursuant to Section 10.1 as of the effective date of such termination then Tibotec shall invoice Gilead for the difference between the amounts previously paid pursuant to Section 10.1 and
[*] and Gilead shall pay such invoice on terms consistent with Section 10.1. Thereafter, Gilead shall have no obligation to pay any additional amounts pursuant to Section 10.1. 
 (b) Termination Due to Withdrawal. Upon termination of this Agreement by either Party pursuant to Section 19.3 with respect to a
given country, the provisions of this Section 19.6(b) shall apply with respect to such country: (i) Section 19.6(a) shall apply, (ii) the Parties shall coordinate in good faith to wind down matters relating to the Manufacture and
supply of the Territory Combination Product with respect to the terminated country, including the appropriate disposition of any Territory Combination Product then in the applicable Party’s (or its Affiliate’s) inventory to the extent not
usable for commercialization in the non-terminated countries, if any, and appropriate financial adjustments with respect to such inventory pursuant to Section 13.3, and (iii) in the case of clause (b) of Section 19.3 (i.e., the
Combination Product has not yet been withdrawn in such country), the Territory Combination Product shall be withdrawn from the market in such country in accordance with Section 13. 
 (c) Termination Due to Material Breach. If this Agreement is terminated for a Material Breach, then the provisions of clause
(b) of this Section 19.6 shall apply. If this Agreement is terminated by Tibotec for a Material Breach of Gilead before Gilead has paid [*] pursuant to Section 10.1, then Tibotec shall invoice Gilead for the difference between
the amounts previously paid pursuant to Section 10.1 and [*] and Gilead shall pay such invoice on terms consistent with Section 10.1. Except to the extent expressly precluded by this Agreement, the aggrieved Party may also seek
damages and other relief for such Material Breach and (for the avoidance of doubt) for any other breach of this Agreement. 
 (d) Post-Launch Voluntary Termination by Tibotec. Upon termination of this Agreement by Tibotec pursuant to Section 19.5(e) with respect to a Region (where “Region” shall mean either (x) the United States
and Canada, or (y) all countries in the Territory other than the United States and Canada, as the case may be), the provisions of this Section 19.6(d) shall apply with respect to such terminated Region: 
 (i) Gilead shall have the right, for [*] after receipt of the notice from Tibotec with respect to such termination, to notify Tibotec
in writing if it desires to continue to distribute and commercialize the Combination Product in the terminated Region. If Gilead timely elects to continue to distribute and commercialize the Combination Product in the terminated Region, the
remainder of this Section 19.6(d), other than Section 19.6(d)(ix), shall apply. If Gilead does not so timely elect to continue to distribute and commercialize the

 (ii) The Parties shall enter into good faith negotiations with respect to one or more written agreements (or amendments to this Agreement
or the Ancillary Agreements, as applicable) pursuant to which Tibotec (or, at the election of Tibotec, a designee of Tibotec) would continue to supply Gilead with the Supplied TMC278 for use in the Manufacture of the Combination Product for sale or
Distribution in the terminated Region, on a non-exclusive basis, in quantities as Gilead may reasonably request, subject to the TMC278 Supply Agreement until such time as Gilead or its designee has been enabled to manufacture TMC278 in accordance
with this clause (ii), or for such longer period as Tibotec may agree in its sole discretion; provided that in no event shall this Section 19.6(d) obligate Tibotec to supply any TMC278 beyond [*]. Tibotec shall (A) enable Gilead to
Manufacture quantities of TMC278 in the form supplied under the TMC278 Supply Agreement for use in the Manufacture of the Combination Product for distribution in the terminated Region, (B) automatically be deemed to grant a royalty-free
nonexclusive worldwide license to Gilead under Tibotec’s and its Affiliates’ Patents and Information and Inventions covering the Manufacture of TMC278 in the form supplied under the TMC278 Supply Agreement or the composition or use of
TMC278 in such form to Manufacture the TMC278 in such form for inclusion in the Combination Product in the form sold as of the date of termination of this Agreement for sale or distribution in the terminated Region (and to so sell or distribute such
Combination Product), which license shall be sublicensable to any Third Party Distributor or Affiliate of Gilead and shall permit Gilead to engage a contract manufacturer to conduct such Manufacture, and (C) provide reasonable technical
assistance to Gilead or its designee (which designee shall be subject to the prior approval of Tibotec, such approval not to be unreasonably withheld or delayed), at Gilead’s expense at [*] to enable the foregoing Manufacture. Tibotec
will be deemed to have satisfied all obligations to enable Gilead or its designee to manufacture the TMC278 (in API or other form) where it has provided (i) information on equipment, process conditions, starting materials, and procedures known
to Tibotec to achieve yields equivalent to those then currently obtained by Tibotec and (ii) consultation with Tibotec’s skilled scientists and production experts as reasonably necessary to enable Gilead to act on the information provided
by Tibotec hereunder. 
 (iii) The license grants in Section 9.4 made by Tibotec to Gilead shall survive to the extent
necessary to enable Gilead to identify Tibotec on the Product Label and Insert for the Combination Product to be sold or distributed in the terminated Region, as approved by the applicable Regulatory Authorities in the terminated Region, in each
case solely to the extent required by Applicable Law. 
 (iv) Except to the extent necessary to enable Gilead to identify
Tibotec (or its applicable Affiliate) on the Product Label and Insert approved by the applicable Regulatory Authorities for the Combination Product to the extent required by Applicable Law, Gilead shall not (and shall cause its Affiliates not to)
use the Trademark or name of Tibotec (or any of its Affiliates) (A) on any labeling, packaging and advertising materials for the

disposal, at Gilead’s option, of any Confidential Information of Gilead, in tangible or intangible form, except for (A) one (1) copy which may be retained solely for archival purposes and (B) Confidential Information relating to
(1) any surviving licenses and other rights pursuant to this Agreement or any Ancillary Agreement or (2) any surviving obligations of Tibotec under this Agreement or any Ancillary Agreement or (3) any Region as to which termination
has not yet occurred.

extent relating to the terminated Region pursuant to the terms of such Tibotec Distribution Agreement. 
 (ix) In the event

Manufacture and supply of the Territory Combination Product with respect to the terminated Region, including the appropriate disposition of any Territory Combination Product then in the applicable Party’s (or its Affiliate’s) inventory to
the extent not usable for commercialization in the non-terminated Region, if applicable, and appropriate financial adjustments with respect to such inventory so that the Party holding such inventory pays the other Party an amount for its APIs that
is equal to the [*]. 
 (e) Post-Launch Voluntary Termination by Gilead. Upon termination of this Agreement by
Gilead pursuant to Section 19.5(d) with respect to a Region, the provisions of this Section 19.6(e) shall apply with respect to such Region: 
 (i) Tibotec shall have the right, for [*] after receipt of the notice from Gilead with respect to such termination, to notify Gilead that it desires to distribute and commercialize the Combination

 19.7 Accrued Liabilities; Survival.  
 (a) Termination of this
Agreement, in whole or in part, shall be without prejudice to any liabilities that shall have accrued prior to such termination or any remedies to which either Party may be entitled. Such termination shall not relieve a Party from obligations that
are expressly indicated to survive the termination of this Agreement. In the event that there are any outstanding credit notes that were issued pursuant to this Agreement as of the date of any such termination, the issuing Party shall pay, promptly
and in no event later than forty-five (45) days after such termination, to the non-issuing Party the amount set forth in such outstanding credit notes and, upon such payment, such notes shall no longer be in effect.

Annexes to the extent applicable to the other surviving terms of this Agreement, shall survive such termination (with respect to the terminated Region, if applicable). 
 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). For purposes of this Agreement a force majeure shall not include a failure to commit sufficient resources, financial
or otherwise, to the activities to be conducted pursuant to this Agreement or general market or economic conditions. 
 20.2
Notice. All notices, requests, reports, statements and other communications to either Party shall be in writing, shall refer specifically to this Agreement and shall be delivered personally, sent by nationally-recognized overnight courier,

 Any such communication shall be deemed to have been given (a) when delivered, if personally
delivered during the recipient’s normal business hours, (b) on the Business Day after dispatch, if sent by nationally-recognized overnight courier and proof of delivery is obtained, (c) on the Business Day following electronic
confirmation of receipt, if sent by facsimile, and (d) on the third (3rd) Business Day following the date of mailing, if sent by mail. 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

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

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

evidence. A transcript of the testimony adduced at the hearing shall be made and shall, upon request, be made available to either Party. 
 (f) The arbitrator(s) are expressly empowered to decide dispositive motions in advance of any hearing, including but not limited to motions
to dismiss and motions for summary judgment, and shall endeavor to decide such motions as would a Federal District Judge sitting in the State of New York. 
 (g) The arbitrator(s) shall decide the issues presented in accordance with the governing law set forth in Section 20.6. The arbitrator(s) shall render a written opinion stating the reasons upon which
the award is based. To the extent possible, the arbitration hearings and award will be maintained in confidence. 
 (h) Nothing
in this Agreement, including this Section 20.7, shall preclude either Party from seeking interim or provisional relief, including a temporary restraining order, preliminary injunction or other interim equitable relief concerning a dispute with
the other Party, either prior to or during the dispute resolution procedures set forth in this Section 20.7, if necessary to protect the interests of such Party. 
 (i) EACH PARTY HERETO WAIVES ANY CLAIM OF DAMAGES TO THE EXTENT THAT SUCH DAMAGES ARE PRECLUDED PURSUANT TO SECTION 18.7. 
 (j) EACH PARTY HERETO WAIVES ANY CLAIM FOR ATTORNEYS’ FEES AND COSTS FROM THE OTHER. 
 (k) EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY. 
 20.8 Consent to Jurisdiction.

 (a) Each Party, for the purpose of enforcing an award under Section 20.7 or for seeking interim or provisional relief as
contemplated in Section 20.7(h) with respect to any breach of this Agreement or any Ancillary Agreement, (i) irrevocably submits to the jurisdiction of the federal and state courts located in the City of New York, State of New York (the
“Court”), and (ii) 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 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. Each Party
further agrees that service of any process, summons, notice or document by U.S. registered mail to such Party’s notice address provided for in this Agreement shall be effective service of process for any action, suit or proceeding in the Court
with respect to any matters to which it has submitted to jurisdiction in this Section 20.8(a).

 (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.

 Annex F 
 Physician Awareness Standard; Required Minimum Details 
 Capitalized terms not defined in this Annex shall have the meanings set forth in the agreement to which this Annex is attached (the “Agreement”). 
 Physician Awareness Standard 
 1. [*] 
 2. [*] 
 3. [*] 
 4. Other Surveys. Either Party, separately or jointly with the other Party or any third party, may conduct other surveys of physician awareness.
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	  	[*]	 	
	ii.	  	France	  	[*]	 	
	iii.	  	Germany	  	[*]	 	
	iv.	  	Italy	  	[*]	 	
	v.	  	Spain	  	[*]	 	
	vi.	  	United Kingdom	  	[*]	 	

 2. Records and Reports. Gilead shall require its sales representatives who Detail the
Combination Product to keep records of their Detailing efforts in accordance with industry standards for the applicable Major Market and sufficient to determine whether or not the required number of Details are achieved and that the requirements of
Section 6.2(b)(iii) are satisfied. Within thirty (30) days after the end of each Detailing Year, Gilead shall provide Tibotec with a written report stating the number of Details for each Major Market. 
 3. Audit. Notwithstanding any provision of Section 12 to the contrary, with reasonable advance notice and not more often than once each Calendar
Year for each Major Market, Tibotec may audit Gilead’s records in order to verify (a) the number of Details in each Calendar Quarter

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

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. 
 5. Other Amounts Included in the Manufacturing
Fees.

 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

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.

 About
Rilpivirine 
 Rilpivirine is an investigational non-nucleoside reverse transcriptase inhibitor being developed by Tibotec
Pharmaceuticals. 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. 
 About Gilead Sciences 
 Gilead Sciences is a biopharmaceutical company that discovers, develops and commercializes innovative therapeutics in areas of unmet medical need. The
company’s mission is to advance the care of patients suffering from life-threatening diseases worldwide. Headquartered in Foster City, California, Gilead has operations in North America, Europe and Australia. 
 This press release includes forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, that are subject to
risks, uncertainties and other factors, including risks related to whether ongoing clinical trials for rilpivirine will be successful and whether rilpivirine will receive regulatory approval, our ability to formulate the combination product or to
perform clinical trials and our ability to obtain FDA and other regulatory approvals. As a result, the combination product may never be successfully commercialized. Further, the parties may make a strategic decision to discontinue development of the
combination product if, for example, we are unable to successfully formulate the fixed-dose combination or the market for the product fails to materialize as expected. These risks, uncertainties and other factors could cause actual results to differ
materially from those referred to in the forward-looking statements. The reader is cautioned not to rely on these forward-looking statements. These and other risks are described in detail in Gilead’s Quarterly Report on Form 10-Q for the
quarter ended March 31, 2009, as filed with the U.S. Securities and Exchange Commission. All forward-looking statements are based on information currently available to Gilead, and Gilead assumes no obligation to update any such forward-looking
statements.

 “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.

 Annex U-1 
 Tibotec Form of Guarantee 
 TIBOTEC GUARANTEE
AGREEMENT 
 GUARANTEE AGREEMENT (this “Agreement”), dated as of
[            ], 2009, by [*] (“Guarantor”), in favor of Gilead Sciences, Inc., a Delaware corporation (“Gilead Parent”) and Gilead Sciences
Limited, a corporation organized and existing under the laws of Ireland and a wholly-owned subsidiary of Gilead Parent (“Gilead Sub”). Gilead Parent and the Gilead Sub are referred to in this Agreement collectively as
“Gilead” or the “Guaranteed Parties” and individually as a “Guaranteed Party.” 
 WHEREAS, Tibotec Pharmaceuticals, a company organized and existing under the laws of Ireland (“Tibotec”) and the Guaranteed Parties are entering into that certain License and Collaboration Agreement, dated as of the date
hereof (as it may be amended from time to time, the “Collaboration Agreement”), which provides, on the terms and conditions set forth in the Collaboration Agreement, for the development and commercialization in the Territory of a
fixed-dose, co-formulated combination product containing TDF, FTC and TMC278 as its only active ingredients (capitalized terms which are used in this Agreement but not otherwise defined in this Agreement shall have the meanings ascribed thereto in
the Collaboration Agreement); 
 WHEREAS, as an inducement to the Guaranteed Parties to consummate the transactions contemplated
by the Collaboration Agreement, Guarantor is executing and delivering this Agreement upon the execution and delivery of the Collaboration Agreement; and 
 NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 
 1. GUARANTEE. 
 1.1
Guaranteed Obligations. [*]. 
 1.2 Obligations Unconditional. The obligations of Guarantor under this
Article 1 shall constitute a present and continuing guarantee of payment and not of collectability, and shall be absolute and unconditional. Without limiting the generality of the foregoing (but subject to Section 1.3 and Section 2.2
hereof), it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of Guarantor hereunder: 
 [*]. 
 1.3 Certain Exceptions. 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 an Affiliate of Tibotec Parent, Guarantor shall have no

 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 Parties proceed first against the Tibotec 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 any of the Guaranteed Parties, on the one hand,
and any Tibotec Entity, on the other hand, 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 Parties 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 Tibotec Entity. Nothing contained in this Agreement shall affect the right of Guarantor to assert (x) any claim it may have against any Guaranteed Party (or its successors or assigns) in a separate action or proceeding or (y) any
defense, set off or counterclaim that any Tibotec Entity may have against any 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 any Guaranteed Party to any Person for any reason whatsoever (including, without limitation, the insolvency, bankruptcy, or
reorganization of any Tibotec 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 Parties. 
 2. MISCELLANEOUS. 
 2.1
Representations and Warranties. 
 Guarantor hereby represents and warrants to Gilead Parent and Gilead Sub that:

 (a) Guarantor (i) has the power and authority and the legal right to enter into this Agreement and to perform its
obligations under this Agreement and (ii) has taken all necessary action on its part required to authorize the execution and delivery of this Agreement. This Agreement has been duly executed and delivered on behalf of Guarantor and constitutes

under, any contractual obligation or court or administrative order by which Guarantor is bound. 
 2.2 Assignability; Binding
Effect. Guarantor, on the one hand, and any of the Guaranteed Parties, on the other hand, 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 Parties[*] 
 2.3 Counterparts. This Agreement may be executed simultaneously in two (2) or more counterparts, each of which shall be deemed
an original, but all of which together shall constitute and be the same instrument.

 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. The language used in this Agreement shall be deemed to be the language chosen by Guarantor and the Guaranteed Parties to express their mutual intent, and no rule of strict construction shall be applied against
any party on account of such party’s drafting of any provision hereof. 
 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 Parties and any waiver of rights hereunder must be set
forth in writing signed by the party against whom the waiver is to be effective.

 AMENDMENT NUMBER 4 TO 
 SOLAR WAFER SUPPLY AGREEMENT 
 This Amendment
Number 4 to Solar Wafer Supply Agreement (this “Fourth Amendment”) is entered into as of September 22, 2009 by and between MEMC SINGAPORE PTE. LTD., a Singapore corporation (“MEMC Singapore”) and
wholly-owned subsidiary of MEMC ELECTRONIC MATERIALS, INC., a Delaware corporation with its principal place of business at 501 Pearl Drive (City of O’Fallon), St. Peters, Missouri 63376, United States of America (“MEMC”), or
such other designated majority-owned subsidiary of MEMC, and GINTECH ENERGY CORPORATION, a Taiwan corporation with its principal place of business at 8F, no. 396, Sec. 1 Neihu Rd. Neihu Technology Park, Taipei 114, Taiwan
(“Gintech”), or its designated majority-owned subsidiary. MEMC Singapore and Gintech together shall be referred to as the “Parties” and individually as a “Party”. 
 RECITALS: 
 WHEREAS, on October 25, 2006, MEMC and Gintech entered into that certain Solar Wafer Supply Agreement (the “Agreement”), pursuant to which MEMC agreed to supply and Gintech agreed to purchase certain quantities of
solar wafers, pursuant to the terms of the Agreement; and 
 WHEREAS, on October 25, 2006, pursuant to Section 7.6 of
the Agreement, MEMC assigned the Agreement to its wholly-owned subsidiary, MEMC Singapore; and 
 WHEREAS, on October 25,
2007, MEMC and Gintech entered into that certain Amendment Number 1 to Solar Wafer Supply Agreement (the “First Amendment”), pursuant to which MEMC agreed to supply and Gintech agreed to purchase certain additional quantities of
solar wafers, pursuant to the terms of the First Amendment; and 
 WHEREAS, on November 30, 2008, MEMC Singapore and
Gintech entered into that certain Amendment Number 2 to Solar Wafer Supply Agreement (the “Second Amendment”), pursuant to which MEMC agreed to certain non-price and volume changes to the Agreement; and 
 WHEREAS, on February 16, 2009, MEMC Singapore and Gintech entered into that certain Amendment Number 3 to Solar Wafer Supply Agreement
(the “Third Amendment”), pursuant to which Gintech and MEMC Singapore agreed to certain changes to the Agreement related to 2009 price and volume; and 
  

 1 

 WHEREAS, the Parties hereto wish to amend the Agreement, as amended by the First Amendment,
Second Amendment, and Third Amendment, and as provided herein by this Fourth Amendment: 
 NOW, THEREFORE, in consideration of
the foregoing and the mutual representations, warranties, covenants and agreements herein contained, MEMC Singapore and Gintech agree as follows: 
 ARTICLE I 
 AMENDMENT TO SELECTED SECTIONS OF THE AGREEMENT 
 1.1 Defined Terms. Capitalized terms used herein and not otherwise defined herein shall have the meanings set forth in the Agreement.

 1.2 Revision of Attachment B to the Agreement, Attachment B-1 to the First Amendment and Attachment B-3 to the Third
Amendment. Notwithstanding the price and volume schedules set forth in the Agreement, the First Amendment or the Third Amendment, the Parties have agreed to amend and revise the price and minimum volumes for the remainder of Contract Year three
(specifically, Q3 and Q4 of calendar year 2009) only by amending the Multi Wafer Price per Watt for Contract Year three (specifically, only Q3 and Q4 of calendar year 2009) and Yearly Minimum Quantity rows for Contract Year three on Attachment
B to the Agreement (as Attachment B to the Agreement was revised as set forth on Attachment B-1 to the First Amendment and as revised further and set forth on Attachment B-3 to the Third Amendment) and to Attachment
B-1 to the First Amendment and Attachment B-3 to the Third Amendment, all as is set forth on Section 1.2 of Attachment B-4 to this Fourth Amendment. 
 1.3 Rolling Forecasts and Binding Purchase Orders; Minimum Revenue Requirement. 
 (a) Rolling Forecasts and Binding Purchase Orders. Pursuant to Section 2.2(e) of the Agreement, Gintech is
required to provide twelve month rolling forecasts to MEMC, and pursuant to Section 2.3 of the Agreement, Gintech is required to maintain at all times binding purchase orders with MEMC for at least the next ninety (90) days. As of
January 13, 2009, Gintech had not met either of these obligations, which failure continues as of the date hereof. Gintech affirms that it will use best efforts to comply with the binding purchase orders requirement of Section 2.3 of the
Agreement and the twelve month rolling forecast requirement of Section 2.2(e) of the Agreement. MEMC Singapore acknowledges that any rolling forecasts provided by Gintech beyond day 90 are not intended to be binding on Gintech. 
 (b) Minimum Revenue Requirement for Contract Year 3. The net end result of the revisions reflected in the Third
Amendment was to maintain the same aggregate revenue commitment from Gintech to MEMC Singapore for Contract Year 3 (the “Contract Year 3 Revenue Amount”) as Gintech had previously committed to MEMC Singapore in the Agreement and in
the First Amendment. Gintech did not take any of the Third Amendment required volumes in Q2 2009, and has indicated an inability to take the Third Amendment required volumes in Q3 2009 and Q4 2009, and as a result, the

  

 2 

 
Parties have agreed with this Fourth Amendment to further revise the Contract Year 3 (calendar 2009) minimum quantities and prices as is set forth on Attachment B-4 to this Fourth
Amendment. The Contract Year 3 aggregate revenue to MEMC Singapore if Gintech complies with the provisions of this Fourth Amendment will be less than the Contract Year 3 Revenue Amount. The amount by which the aggregate revenue to MEMC Singapore
from actual purchases made by Gintech in Contract Year 3 is less than the Contract Year 3 Revenue Amount is the “Contract Year 3 Purchase Shortfall.” 
 (c) Contract Year 3 Purchase Shortfall – Possible Deferral. Gintech agrees and acknowledges that the Contract
Year 3 Purchase Shortfall would be due and payable to MEMC Singapore in accordance with the provisions of Section 2.2(d) and Section 3.1 of the Agreement. The Parties now hereby agree in this Fourth Amendment that the payment to MEMC
Singapore of the Contract Year 3 Purchase Shortfall in accordance with the timetable set forth in Section 2.2(d) and Section 3.1 of the Agreement may nonetheless be deferred by Gintech if all of the following conditions are met:

 (i) Notwithstanding any other provision of this Fourth Amendment, Gintech agrees that the quantities of Watts
actually purchased and paid for by Gintech from MEMC Singapore in the third quarter of Contract Year 3 and the fourth quarter of Contract Year 3 shall in any event be at least *** (***) in the third quarter of Contract Year 3 and at least *** (***)
in the fourth quarter of Contract Year 3; and 
 (ii) If, as of January 15, 2010, Gintech is current in all
payments due to MEMC Singapore, in accordance with the terms of Section 2.7 of the Agreement; and 
 (iii)
If, by no later than the required dates set forth in the Agreement, Gintech has provided the required Loan/Security Deposit Amount and Letter of Credit Amount (and Letter of Credit) for Contract Year 4 to MEMC Singapore (as the same may be agreed by
the Parties in the future, including pursuant to the provisions of Section 1.6 below). 
 If all of the foregoing conditions
are met, then Gintech may defer the payment to MEMC Singapore of the Contract Year 3 Purchase Shortfall, and perhaps eliminate some or all of it, by purchasing (A) additional Watts in Contract Year 4 (above the Yearly Minimum Quantities for
Contract Year 4 currently set forth in the Agreement and all prior Amendments) with additional incremental aggregate revenue to MEMC Singapore equal to *** (***) of the amount of the Contract Year 3 Purchase Shortfall; and (B) additional
Watts in Contract Year 5 (above the Yearly Minimum Quantities for Contract Year 5 currently set forth in the Agreement and all prior Amendments) with additional incremental aggregate revenue to MEMC Singapore equal to *** (***) of the amount of the
Contract Year 3 Purchase Shortfall; and (C) additional Watts in Contract Year 6 (above the Yearly Minimum Quantities for Contract Year 6 currently set forth in the Agreement and all prior Amendments) with additional incremental aggregate
revenue to MEMC Singapore equal to *** (***) of the amount of the Contract Year 3 Purchase Shortfall; and (D) additional Watts in Contract Year 7 (above the Yearly Minimum

  

 3 

 
Quantities for Contract Year 7 currently set forth in the Agreement and all prior Amendments) with additional incremental aggregate revenue to MEMC Singapore equal to *** (***) of the amount of
the Contract Year 3 Purchase Shortfall; and (E) additional Watts in Contract Year 8 (above the Yearly Minimum Quantities for Contract Year 8 currently set forth in the Agreement and all prior Amendments) with additional incremental
aggregate revenue to MEMC Singapore equal to *** (***) of the amount of the Contract Year 3 Purchase Shortfall. 
 (d) Future Contract Years — Purchase Shortfalls and Possible Deferrals. In the Agreement, the First Amendment and the Third Amendment, Gintech had previously committed to purchase certain Yearly Minimum Quantities from MEMC
Singapore, on a set price curve, which would have resulted in minimum aggregate revenues in each Contract Year to MEMC Singapore (the minimum aggregate revenue for each Contract Year, the “Contract Year X Revenue Amount”). For
Contract Year 3 and future Contract Years, Gintech has requested relief from (x) the take or pay provisions of Section 2.2 of the Agreement and (y) the requirement of payment of any Purchase Shortfalls under Section 2.2(d) of the
Agreement immediately after the conclusion of any Contract Year (pursuant to the provisions of Section 2.2(d)). MEMC Singapore is unwilling to provide such unconditional relief from these take or pay and Purchase Shortfall provisions for future
Contract Years, but MEMC Singapore is willing to provide Gintech with an opportunity to defer the immediate payment of Purchase Shortfalls for future Contract Years (as MEMC has provided for Contract Year 3 in Section 1.3(c) above), pursuant to
the procedures set forth in Section 1.4 below, including specifically Section 1.4(e). The amount by which the aggregate revenue to MEMC Singapore from actual purchases made by Gintech in any individual Contract Year is less than the
Contract Year X Revenue Amount is the “Contract Year X Purchase Shortfall.” 
 1.4 Yearly Minimum Quantity
Amounts for future Contract Years. 
 (a) Additions to Yearly Minimum Quantity Generally. Assuming
that Gintech’s actual Watts purchased in Contract Year X produces a Contract Year X Purchase Shortfall, then the Yearly Minimum Quantity required to be purchased by Gintech (without triggering a right for MEMC Singapore to recover immediately
for a Purchase Shortfall after the conclusion of that Contract Year pursuant to Section 2.2(d) of the Agreement) in any particular future Contract Year shall be equal to at least (i) the Yearly Minimum Quantity for such Contract Year;
plus (ii) the quantity of Watts equal to the amount of the Contract Year 3 Purchase Shortfall required to be purchased in that Contract Year as described in Section 1.3(c) above, if any; plus (iii) the quantity of Watts
equal to the amount of the Contract Year X Purchase Shortfall required to be purchased in that Contract Year as described in Section 1.3(d) above and as calculated in Section 1.4(b) below, if any; plus (iv) the quantity of
Watts equal to the Demand Limitation Rollover Amount rolled over into the next succeeding Contract Year pursuant to Section 1.4(e)(iii) hereof; provided, however, that Gintech’s actual purchases in any Contract Year shall not be
less than *** (***) of Gintech’s demand for such Contract Year (such demand shall be calculated exclusive of any tolling that Gintech may do for third parties), unless Gintech has already made up all outstanding Contract Year X Purchase
Shortfalls prior to or during such Contract Year; and provided, further that if Gintech’s actual

  

 4 

 
purchases in any Contract Year are less than *** (***) of Gintech’s demand for such Contract Year (again, unless Gintech has already made up all outstanding Contract Year X Purchase
Shortfalls prior to or during such Contract Year), then the deferral by MEMC Singapore of its right to collect immediately for any Purchase Shortfalls shall lapse, and all such deferred Purchase Shortfalls shall be due and payable immediately.

 (b) Additions to Yearly Minimum Quantities for Contract Year 4 through Contract Year 11 Mechanics. For
any Contract Year in which Gintech’s actual purchases and the provisions of Section 1.3(d) above and the provisions of Section 1.4(a) above would produce a Contract Year X Purchase Shortfall, then the Parties agree that *** (***) of
the amount of such Contract Year X Purchase Shortfall shall be added to the Yearly Minimum Quantity for each of the next *** (***) Contract Years (as is required by Section 1.4(a)(iii) above). By way of example only, the Parties have set forth
on Attachment B-4 to this Fourth Amendment a revised table that includes the Yearly Minimum Quantities for each future Contract Year, based on the provisions of Section 1.3 (deferrals related to Purchase Shortfalls) and Section 1.4
hereof (Demand Limitation Rollover Amounts), assuming that the price per Watt for Q4 2009 is the price per Watt for each future Contract Year, and showing how such amounts will be rolled forward into future Contract Years if Gintech is in compliance
with all of the requirements for such deferrals set forth in Section 1.3 and Section 1.4 hereof. The actual Yearly Minimum Quantities will be higher or lower based on the actual prices per Watt in future Contract Years, as is required by
Section 1.4(d) below. 
 (c) Contract Year 11. The Parties hereto understand that the deferral and
roll-forward provisions of Section 1.3 and Section 1.4 hereof could produce a Yearly Minimum Quantity amount in Contract Year 11 that is greater than the *** (***) of Gintech’s demand limitation of Section 1.4(a) above. In such
event, the Parties hereby agree that such amounts will be similarly rolled forward into future years, and that the Agreement will be automatically extended for such number of years until Gintech has purchased all of its required Yearly Minimum
Quantities (the Parties acknowledge that after Contract Year 11, there will only be “make-up” quantities from Section 1.4(a)(iii) above, if any, left to purchase after Contract Year 11). For the avoidance of doubt, the Parties hereby
agree that once Gintech’s actual purchases have reached the aggregate revenue commitment from Gintech to MEMC Singapore during the life of the Agreement (as the Agreement may be extended pursuant to this Section 1.4(c)), the payment to
MEMC Singapore of any Purchase Shortfalls in accordance with Section 2.2(d) and Section 3.1 of the Agreement will be eliminated by MEMC Singapore. 
 (d) Consequence of Further Price Reductions or Increases. If the Parties subsequently reduce pricing for all or a
portion of any future Contract Year, then the Yearly Minimum Quantities for such future Contract Years will increase by a corresponding amount (all with the purpose of maintaining the same aggregate revenue commitment from Gintech to MEMC Singapore
for such Contract Year and/or the life of the Agreement (as the Agreement may be extended pursuant to Section 1.4(c) hereof)), and the quantity of Watts equal to the additional incremental Contract Year X Purchase Shortfall amount will be added
to this revised Yearly Minimum Quantity for each such Contract Year. The pricing for any such Wafers would be at the then prevailing price per

  

 5 

 
Watt under the Agreement or any Amendments thereto. Similarly, if pricing is increased for all or a portion of any future Contract Year, then the Yearly Minimum Quantities for such future
Contract Years will decrease by a corresponding amount. 
 (e) Contract Year X Purchase Shortfalls –
Possible Deferrals. Gintech agrees and acknowledges that any Contract Year X Purchase Shortfalls would be due and payable to MEMC Singapore in accordance with the provisions of Section 2.2(d) and Section 3.1 of the Agreement. The
Parties now hereby agree in this Fourth Amendment that the payment to MEMC Singapore of the Contract Year X Purchase Shortfall in accordance with the timetable set forth in Section 2.2(d) and Section 3.1 of the Agreement may nonetheless be
deferred by Gintech if all of the following conditions are met: 
 (i) Notwithstanding any other provision of
this Fourth Amendment, Gintech and MEMC Singapore shall agree, at least thirty (30) days before the start of each Contract Year X, on the minimum quantities of Watts to be purchased by Gintech from MEMC Singapore in each calendar quarter of the
upcoming Contract Year X (and these minimum quantities of Watts for Contract Year X will be based on the provisions and limits of Section 1.3 and Section 1.4 hereof); and 
 (ii) Notwithstanding any other provision of this Fourth Amendment, Gintech agrees that the quantities of Watts actually
purchased and paid for by Gintech from MEMC Singapore in any particular calendar quarter of any future Contract Year X shall be no less than *** (***) of Gintech’s quarterly demand (such demand shall be calculated exclusive of any tolling that
Gintech may do for third parties in the quarter), unless the Parties mutually agree to a lesser demand for one or more calendar quarter pursuant to Section 1.4(e)(i) above, which lesser demand would need be made up by Gintech in a subsequent
calendar quarter within Contract Year X; and 
 (iii) Notwithstanding any other provision of this Fourth
Amendment, Gintech agrees that the aggregate quantity of Watts actually purchased and paid for by Gintech from MEMC Singapore in any Contract Year X shall be equal to at least the lesser of (A) *** (***) of Gintech’s demand for that
Contract Year (and the Parties agree that such demand shall be calculated exclusive of any tolling that Gintech may do for third parties) and (B) the Yearly Minimum Quantity required by Section 1.4(a); provided, however, that
for any Contract Year X where *** (***) of Gintech’s demand for that Contract Year X is less than the Yearly Minimum Quantity for that Contract Year X required by Section 1.4(a), then the amount of the excess of such Yearly Minimum
Quantity will “roll over”, in full, into the immediately following Contract Year (such amount, the “Demand Limitation Rollover Amount”); and 
 (iv) Notwithstanding any other provision of this Fourth Amendment, including specifically the Yearly Minimum Quantity
required by Section 1.4(a), Gintech agrees that its actual demand for Watts to be purchased and paid for by Gintech from MEMC Singapore for Contract Year X shall be equal to or greater than *** (***) of its demand, as such demand is currently
set forth on Attachment B-4 to this Fourth Amendment; and 
  

 6 

 (v) If, as of any such particular future date, Gintech is current in all
payments due to MEMC Singapore, in accordance with the terms of Section 2.7 of the Agreement; and 
 (vi)
If, by no later than the required dates set forth in the Agreement, Gintech has provided the required Loan/Security Deposit Amount and Letter of Credit Amount (and Letter of Credit) for Contract Year X to MEMC Singapore (as the same may be agreed by
the Parties in the future, including pursuant to the provisions of Section 1.6 below). 
 1.5 Future Contract Year
Pricing. Gintech has requested that MEMC Singapore amend the Agreement now to replace the agreed-upon pricing per Watt for each future Contract Year in the Agreement and the First Amendment with a fluctuating quarterly pricing mechanism. Given
MEMC Singapore’s expenditures on capacity expansion predicated on the ten year take-or-pay Agreement and related commitment from Gintech, MEMC Singapore cannot agree to such a blanket price change request. However, MEMC Singapore is willing to
provide Gintech with a quarterly “market” price, on a per Watt basis, which market price shall be determined only on a quarter-by-quarter basis (unless the Parties otherwise specifically agree to a longer time period) if, and only if, all
of the following conditions are met at any particular future date: 
 (a) If, as of any such particular future
date during any future Contract Year, Gintech is current in all payments due to MEMC Singapore, in accordance with the terms of Section 2.7 of the Agreement; and 
 (b) If, as of any such particular future date during any future Contract Year, Gintech has provided, by no later than the
required dates set forth in the Agreement, the required Loan/Security Deposit Amount and Letter of Credit Amount (and Letter of Credit) for each such Contract Year to MEMC Singapore (as the same may be agreed by the Parties in the future pursuant to
the provisions of Section 1.6 below); and 
 (c) If, as of any such particular future date during any future
Contract Year, Gintech has actually purchased the required minimum quantity of Watts required to be purchased as of such date pursuant to the provisions of Section 1.4(a) (including that any previously agreed quarterly linear demand schedules
mutually agreed by the Parties or required by Section 1.4(e)(i) and Section 1.4(e)(ii) had been complied with by Gintech); and 
 (d) If, as of any such particular future date during any future Contract Year, Gintech has not (i) become insolvent, (ii) made a general assignment for the benefit of creditors,
(iii) suffered or permitted the appointment of a receiver for its business or assets, (iv) become subject as the debtor to any proceeding under any bankruptcy or insolvency Law, whether domestic or foreign, and such proceeding has not been
dismissed with prejudice within sixty (60) days after filing, or (v) commenced liquidation or dissolution proceedings, voluntarily or otherwise. 
  

 7 

 If all of the foregoing conditions are met at any particular future date during any future Contract Year,
then MEMC Singapore agrees that it will determine a competitive price per Watt for the next succeeding calendar quarter (unless the Parties otherwise specifically agree to a longer time period, or shorter time period (such as the next succeeding
calendar month), if market conditions, in MEMC’s reasonable discretion, would require a shorter time period or faster potential price adjustment), and provide Gintech with such competitively determined price. Gintech acknowledges that
(x) such competitive price per Watt will be a price that reflects the stability of supply and quality of MEMC Singapore-supplied Wafers, and will not be merely a “matching” of the lowest spot price available in the market;
(y) any lowering of the price per Watt in a future Contract Year will require a corresponding increase in Gintech’s Yearly Minimum Quantity commitment based on the principles set forth in Section 1.3 and Section 1.4 above; and
(z) prices per Watt under this Section 1.5 could also rise from quarter to quarter as well (which would then dictate a corresponding decrease in Gintech’s Yearly Minimum Quantity commitment based on the principles set forth in
Section 1.3 and Section 1.4 above). 
 1.6 Calculation of revised Loan/Security Deposit Amounts and Letter of
Credit Amounts. Notwithstanding the Letter of Credit Amount rows for future Contract Years set forth on Attachment C to the Agreement (as revised on Attachment B-1 to the First Amendment), the Parties now agree to revise the
Loan/Security Deposit Amount and the Letter of Credit Amount for each future Contract Year based upon the pricing and quantities agreed to by the Parties in accordance with all of the provisions of Section 1.3 and Section 1.4 by using the
same formula set forth in Section 3.1(c) of the Agreement on a Contract Year-by-Contract Year basis, at least sixty (60) days before commencement of each such future Contract Year; provided, however, that the Parties agree that for
calendar 2009 through calendar 2011, MEMC Singapore shall maintain and hold the amounts of the Loan/Security Deposit and Letter of Credit held by MEMC Singapore as of the date hereof as security. Furthermore, notwithstanding anything in the
Agreement or First Amendment to the contrary, unless the Parties otherwise agree in the future, the Parties agree that after the date hereof, for the life of the Agreement (as it may be extended pursuant to Section 1.4(c) hereof), MEMC
Singapore and Gintech will not be required to increase or decrease the Loan/Security Deposit Amount each Contract Year, and no payments back and forth each Contract Year per Section 3.1(a) and Section 3.1(b) will be made by either Party.
The Parties also agree that per Section 3.1 of the Agreement, the aggregate Retained Loan/Security Deposit Amount of *** shall be retained in full by MEMC Singapore at the conclusion of the last Contract Year, with the balance being returned to
Gintech, unless the provisions of the Agreement and any amendment thereto would otherwise permit MEMC Singapore to retain more of the Loan/Security Deposit than such amount. By way of example, the Parties have set forth on Attachment B-4 to
this Fourth Amendment a revised table that includes the current Loan/Security Deposit Amounts and Letter of Credit Amounts assuming that the price per Watt for Q4 2009 is the price per Watt for each future Contract Year. 
  

 8 

 1.7 Right to Have Gintech Toll Cells. 
 (a) Subject to Gintech’s production capacity, Gintech agrees to convert (or “toll manufacture”) wafers into
cells for designated third parties of MEMC Singapore (a “Designated Third Party”) at the cost to convert set forth on Attachment B-4 to this Fourth Amendment. The Parties agree to work together to reduce this cost to convert
over the life of the Agreement, and the Parties will amend Attachment B-4 accordingly as these reductions occur. 
 (b) This tolling charge (or cost to convert) charged to the Designated Third Party will be the most favorable price (lowest price) charged by Gintech to any of its customers on substantially the same supply terms and conditions, and in any
event shall not exceed the maximum cost set forth on Attachment B-4. MEMC Singapore shall have the right, on behalf of the Designated Third Party, to audit Gintech’s books and records, upon reasonable prior notice to Gintech, to ensure
compliance with this Section 1.7(b). 
 (c) In the event that the Designated Third Party desires to have
Gintech toll cells, the Designated Third Party shall convey such request and its wafer delivery plan in writing to Gintech by a date no less than twenty five (25) Business Days before MEMC Singapore or the Designated Third Party delivers the
wafers to Gintech. Gintech shall provide the Designated Third Party with a workable cell delivery plan for cells manufactured with such wafers no later than ten (10) Business Days after receipt of such wafer delivery plan. Gintech reserves the
right to refuse or delay the acceptance of such request due to production capacity constraints, and if Gintech does so refuse or delay such acceptance, Gintech will communicate such refusal or delay no later than five (5) Business Days after
receipt of such request and wafer delivery plan. In the event Gintech accepts the request, Gintech shall manufacture such cells and deliver them to the Designated Third Party in accordance with said cell delivery plan, but in any event no later than
thirty (30) Business Days after receipt of the wafer delivery plan. Payment for such cell purchases shall be thirty (30) days after receipt of the invoice for delivered product by the Designated Third Party. 
 1.8 Section 2.14 – Continuous Improvement. Pursuant to Section 2.14 of the Agreement, the Parties agreed to work
together on continuous improvement efforts to Wafers and Wafer specifications. In order to allow MEMC Singapore to offer the Wafer price reduction offered by this Fourth Amendment, the Parties have now agreed to cooperate with each other to reach a
*** Wafer thickness as soon as reasonably practicable. 
 1.9 Board Observer. In light of MEMC Singapore’s existing
investment in Gintech, and any potential future investment in Gintech, Gintech shall invite an individual appointed by MEMC to attend the Board meeting of Gintech (the “Gintech Board Observer”); provided that the Gintech Board
Observer will not have voting rights toward the matters discussed at any such Board meeting and MEMC and MEMC Singapore shall keep any information obtained and any decisions made at any such Board meeting in strict confidence. MEMC Singapore’s
initial Gintech Board Observer shall be as previously communicated to Gintech. MEMC Singapore may change the individual appointed as the Gintech Board Observer from time to time, and Gintech shall reasonably accommodate such changes, should they
occur. 
  

 9 

 1.10 Additional Consideration to be provided by Gintech. Gintech acknowledges that
MEMC Singapore has agreed to forego significant economic and other rights by offering the price reduction included in this Fourth Amendment. In exchange for this price reduction, Gintech agrees to use its best efforts to transfer the items set forth
on Attachment B-4, Section 1.10, to this Fourth Amendment to MEMC Singapore as soon as practicable, and in any event by no later than thirty (30) days after the date of this Fourth Amendment. 
 ARTICLE II 
 MISCELLANEOUS 
 2.1 No Other Changes. Other than with respect to the Sections of the Agreement specifically
enumerated above, this Fourth Amendment does not modify, change or delete any other addendum, term, provision, representation, warranty or covenant (the “Provisions”) relating to or contained in the Agreement or any Attachment, and
all such Provisions of the Agreement shall remain in full force and effect. 
 2.2 No Waiver. By agreeing to this Fourth
Amendment, in no way is MEMC Singapore waiving any past actions or inactions by Gintech under the Agreement or any Amendments thereto, or consenting to any future action or inactions by Gintech under the Agreement or any Amendments thereto. The
failure of a Party hereto at any time or times to require strict performance of any provision hereof or claim damages with respect thereto shall in no manner affect its right at a later time to enforce the same. No waiver by a Party of any condition
or of any breach of any term, covenant, representation or warranty contained in this Fourth Amendment shall be effective unless in writing, and no waiver in any one or more instances shall be deemed to be a further or continuing waiver of any such
condition or breach in other instances or a waiver of any other condition or breach of any other term, covenant, representation or warranty. 
 2.3 Amendment; Entire Agreement. This Fourth Amendment may be amended, modified or supplemented only in writing signed by MEMC Singapore and Gintech. This Fourth Amendment sets forth the entire
agreement and understanding of the Parties hereto with respect to the specific amendment(s) to the Agreement contemplated hereby and supersedes any and all prior agreements, arrangements and understandings, both written and oral, among the Parties
relating to the subject matter of this Fourth Amendment. 
 2.4 Applicable Law. This Fourth Amendment shall be governed
by and construed and enforced in accordance with the internal Laws of the State of New York, without giving effect to the principles of conflicts of law thereof. 
 2.5 Counterparts; Facsimile Signatures. This Fourth Amendment may be executed in counterparts, and when so executed each counterpart shall be deemed to be an original, and said counterparts
together shall constitute one and the same instrument. This Fourth Amendment may be executed and delivered by facsimile and upon such delivery the facsimile signature shall be deemed to have the same effect as if the original signature had been
delivered to the other Part(ies). The original signature copy shall be delivered to the other Part(ies) by express overnight delivery. The failure to deliver the original signature copy and/or the nonreceipt of the original signature copy shall have
no effect upon the binding and enforceable nature of this Fourth Amendment.
