SECTION 3.

DEVELOPMENT ACTIVITIES

3.1 General. Under the oversight of the JDC, Gilead and BMS shall each perform, or cause its Affiliates to perform, on behalf of and in the name of the JV, the Development Activities designated for such Member Party in the Development Plan, in each case in accordance with the timeline set forth in the Development Plan. For the avoidance of doubt, Gilead, on its own behalf and in its own name, shall have the sole right to [ * ] in its sole discretion and without oversight by the JDC or the JEC, but shall [ * ] with respect to [ * ] of such [ * ].

3.2 Clinical Development.

(a) Without limitation of Section 3.1, Gilead, under the oversight of the JDC, shall have primary responsibility for the development of the Combination Product and the conduct of any clinical trials and bioequivalence studies required for obtaining approval of (i) an NDA for the Combination Product in the United States in the Field, and (ii) an NDS for the

-36-

Combination Product in Canada in the Field, in each case only as set forth in the Development Plan or otherwise mutually agreed upon by the Member Parties.

(b) In the event that either Member Party desires (i) to conduct or sponsor, or cause to be conducted or sponsored, jointly with the other Member Party, or in the name of the JV, a clinical trial of the Combination Product (whether such clinical trial would involve the Combination Product alone, or with one or more other products) other than any clinical trial contemplated by the Development Plan, including, without limitation, an expanded access program or Phase IIIb/IV study, or (ii) to support jointly with the other Member Party (either on their own behalf or in the name of the JV) any such clinical trial sponsored by an investigator, such Member Party shall so notify the other Member Party. The Member Parties shall then discuss the particulars of the proposed clinical trial. In the event that the Member Parties, each in its sole discretion, agree to conduct jointly or sponsor jointly such clinical trial (either on their own behalf or in the name of the JV), the JDC representatives shall prepare and agree upon a trial protocol and designate a Member Party to take the lead in conducting or supervising such clinical trial and negotiating any necessary clinical trial agreements, as the case may be, and the external, out-of-pocket costs of the Member Parties, if any, without any markup, relating to such clinical trial shall be treated as Authorized Development Expenses. In the event that the Member Parties, each in its sole discretion, agree to support jointly (either on their own behalf or in the name of the JV) any investigator-sponsored clinical trial, the Member Parties shall coordinate with the investigator seeking to conduct such clinical trial and agree upon an appropriate grant of support (including, without limitation, support in the form of funding or the contribution of drug product), and the external, out-of-pocket costs of the Member Parties, if any, without any xxxx up, with respect to such clinical trial shall be treated as Authorized Development Expenses. Each clinical trial that the Member Parties shall determine to conduct, sponsor or support jointly pursuant to the preceding two sentences shall be referred to as a “Co-Funded Clinical Trial.” The Clinical Data with respect to any Co-Funded Clinical Trial shall be deemed to be Joint Know-How; provided, however, that, in the case of any investigator-sponsored clinical trial, the Clinical Data resulting from any such Co-Funded Clinical Trial shall be deemed to be Joint Know-How only if and to the extent that the JV or either or both Member Parties obtains any right, title and interest in and to such Clinical Data.

For the avoidance of doubt, nothing contained in this Section 3.2 is intended, or shall be construed, to restrict or prohibit either Member Party from conducting independently or together with one or more Third Parties, any clinical trial of the Combination Product (whether such clinical trial would involve the Combination Product alone, or with one or more other products). Prior to a Member Party’s commencing any such clinical trial sponsored by such Member Party, whether independently or together with one or more Third Parties, the applicable Member Party shall provide a brief summary of the protocols to the other Member Party’s representatives on the JDC (it being understood that neither such representatives nor the JDC shall have any approval rights with respect to such study or protocols), provided that (A) each such summary shall constitute Confidential Information of the disclosing Member Party to the extent that the information provided in such summary satisfies the criteria set forth in Section 12.3, (B) the receiving Member Party’s representatives shall not use such summary for any purpose other than providing comments thereon to the disclosing Member Party (which

-37-

comments may be accepted or rejected by the disclosing Member Party in its sole discretion), and (C) the receiving Member Party’s representatives shall not disclose such summary to any Persons other than employees of such Member Party who have an obligation (x) not to further disclose such summary and (y) to use such summary solely in order to assist such Member Party’s representatives in providing comments thereon. For the avoidance of doubt, a Member Party’s providing such summary with respect to any such clinical trial pursuant to this Agreement shall not be construed to have the effect of causing the activities with respect to such clinical trial to be deemed to be Project Activities for purposes of this Agreement.

(c) In the event that the Member Parties determine to conduct additional Development Activities for an alternative formulation or presentation of the Combination Product, and conduct or cause to be conducted such additional activities, the external, out-of-pocket costs of the Member Parties, if any, without any markup, with respect to such activities shall be treated as Authorized Development Expenses.

3.3 Formulation and CMC Data. Without limitation of Section 3.1, Gilead, under the oversight of the JDC, shall have primary responsibility for formulation and Manufacturing Process development for, and preparation of the CMC Data relating to, the Combination Product as contemplated by the Development Plan. Formulation development shall include, without limitation, conducting the formulation screening, optimization, scale-up and technology transfer for the Combination Product in the Field.

3.4 Regulatory Matters.

(a) Without limitation of Section 3.1, Gilead, under the oversight of the JDC and with the participation of BMS as described in this Section 3.4, shall have primary responsibility for preparing and filing all necessary Regulatory Documentation and for acting as liaison on behalf of the JV for all communications with the Regulatory Authorities in the Territory relating to the obtaining of approval of the Combination Product in the Field, in the case of the United States, under an NDA separate from the respective NDAs for Sustiva, Viread, Emtriva and Truvada, and in the case of Canada, under an NDS separate from the respective NDSs for Sustiva, Viread, Emtriva and Truvada. Gilead shall prepare and file all Combination Product Regulatory Documentation with Regulatory Authorities in the Territory in the name of the JV. All submissions of Combination Product Regulatory Documentation consisting of any INDs, NDAs, sNDAs, CTAs, NDSs, SNDSs, CMC Data, drug master files and PSURs (collectively, the “Key Regulatory Submissions”) shall be approved in advance by the JDC (which shall not delegate such approval to any subcommittees or groups referred to in Section 2.6(g)). If permitted by Applicable Law, the label for the Combination Product shall list the agents in the following order: [ * ]. For the avoidance of doubt, this Section 3.4(a) shall not apply with respect to obtaining and maintaining the [ * ].

(b) Gilead shall notify BMS as early as reasonably practicable in advance of all meetings (whether face to face or by teleconference) and communications with representatives of the Regulatory Authorities in the Territory concerning the Combination Product and in order to provide BMS with an opportunity to be present at such meetings and to review and comment on such communications; provided, however, that in no event shall Gilead,

-38-

after using reasonable efforts to provide BMS with an opportunity to be present at any such meeting or to review and comment on such communications, be required to postpone any such meeting to ensure that BMS attends such meeting or to postpone any such communication in order to ensure that BMS’ comments are received by Gilead in advance of its submission to Regulatory Authorities, as the case may be. In order to enhance the efficiency of the Member Parties’ coordination on regulatory matters concerning the Combination Product, and increase the likelihood that BMS will have a meaningful opportunity to participate in such activities, during the term of this Agreement, BMS will cause one of its employees with the necessary regulatory expertise and decision-making authority to be dedicated on a full-time basis to serving as a conduit for BMS’ participation in such activities. Gilead shall promptly forward to BMS in advance of any such meeting copies of all documents and other relevant information relating to such meeting. Notwithstanding anything contained in this Agreement to the contrary, (i) at any such meeting with, or any such communication to, the Regulatory Authorities in the Territory concerning the Combination Product, at which BMS and Gilead are present or in which both Member Parties participate, each Member Party shall take the lead on matters relating to its respective Single Agent Product(s) or Double Agent Product and (ii) at any such meeting with, or any such communication to, such Regulatory Authorities concerning the Combination Product, at which only one Member Party meets or in which communication only one Member Party participates (without the other Member Party’s presence or participation), such Member Party shall not engage in any substantive discussions pertaining to the other Member Party’s Single Agent Product(s) or Double Agent Product, as the case may be, including, without limitation, with respect to API consisting of EFV, TDF or FTC, as the case may be, as it relates to the Combination Product. Notwithstanding anything in this Section 3.4(b) to the contrary, this Section 3.4(b) shall not apply with respect to obtaining and maintaining the [ * ].

(c) Each Member Party shall promptly forward to the other Member Party any written communications received from representatives of the Regulatory Authorities relating to the Combination Product. BMS shall provide Gilead with full access to and copies (including electronic copies if requested) of the BMS Regulatory Documentation, including without limitation the NDA and NDS for Sustiva, as Gilead may reasonably request in connection with (and solely for the purpose of) the performance of its duties under this Section 3.4. Notwithstanding anything in this Section 3.4(c) to the contrary, this Section 3.4(c) shall not apply with respect to obtaining and maintaining the [ * ].

(d) Nothing in this Section 3.4 shall prohibit or restrict either Member Party from communicating with the Regulatory Authorities on matters relating to the Exploitation of any of its respective Single Agent Product(s), Double Agent Product or other pharmaceutical products. Each Member Party shall promptly notify the other Member Party of any label change for the first Member Party’s respective Single Agent Product(s) or Double Agent Product that may result in a label change for the Combination Product. If any communications from Regulatory Authorities regarding potential label changes for the Combination Product are reasonably expected to lead to a label change for a Member Party’s Single Agent Product or Double Agent Product, then, notwithstanding anything in this Agreement to the contrary, the affected Member Party shall take the lead in dealing with the Regulatory Authorities on such matter.

-40-

(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 [ * ], in which case [ * ], shall apply. Each such request shall be made in writing and shall state the reason(s) therefor (each a “Development Record Request”). The Member 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, without limitation, based on such Member Party’s interests in protecting from disclosure to the requesting Member Party trade secrets or other competitive business information.

4.1 Clinical Supply. Gilead shall Manufacture or have Manufactured through a subcontractor, on behalf of the JV, clinical supplies of the Combination Product in such quantities as may be needed for the clinical trials and studies required to obtain Approvals of the Combination Product in each country in the Territory. In connection with such Manufacture, Gilead and BMS each shall donate to the JV quantities of FTC and TDF, in the case of Gilead, and EFV, in the case of BMS. Each Member Party’s Cost of Goods of such supply, as well as Gilead’s Cost of Goods for Manufacture of the clinical supplies of the Combination Product, shall not be chargeable to the JV.

4.2 Commercial Supply.

(a) The initial Development Plan designates the initial commercial Supplier of the Combination Product, which Supplier shall be the source of Combination Product supply for purposes of the NDA filing and Launch in the United States. Within [ * ] after the Effective Date, the JCC shall determine the most cost-efficient manner in which to source the commercial supply of the Combination Product, including, without limitation, one or more alternate suppliers. Thereafter, during the term of this Agreement, the JCC shall review annually the appropriate source(s) of commercial supply of the Combination Product after Launch in the United States and agree upon appropriate changes. Each Member Party may propose interim changes with respect thereto from time to time between such reviews, which changes the JCC shall adopt if failure to do so would be likely to have a material adverse effect on the Combination Product business. If Gilead or BMS desires to be considered as a possible Supplier of the Combination Product, it shall submit a confidential written proposal to the JV for consideration by the JCC alongside written proposals submitted by recognized, reliable and sufficiently capitalized Third Parties and/or the supply terms pertaining to the initial Supplier. Any proposal submitted by a possible Supplier shall include an offer to perform any required tableting, blistering, packaging, labeling, analytical testing and storage activities with respect to commercial supplies of the Combination Product. The JCC shall select a Person to supply the

-45-

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 [ * ] in which case [ * ] shall apply. Each such request shall be made in writing and shall state the reason(s) therefore (each a “Commercial Record Request”). The Member Party from which such records, documentation or data are requested shall have the right to raise reasonable objections in writing in response to such Commercial Record Request, including, without limitation, based on such Member Party’s interests in protecting from disclosure to the requesting Member Party trade secrets or other competitive business information.

5.11 Commercialization Plans and Budgets.

(a) The Commercialization Plan for a country in the Territory shall cover only activities for commercialization of the Combination Product in such country that shall be conducted by a single Member Party or that must be coordinated between the Member Parties, which activities shall conform to the Collaboration Principles and the provisions of this Section 5.

-58-

(b) The initial U.S. Commercialization Plan attached hereto as Annex C covers the period from the Effective Date through the Initial Launch Period for the United States (the “U.S. Commercialization Plan”). The initial Canadian Commercialization Plan attached hereto as Annex U covers the period from the Amended Effective Date through the Initial Launch Period for Canada (the “Canadian Commercialization Plan” and together with the U.S. Commercialization Plan, the “Commercialization Plans”). Each Commercialization Plan and any update thereto shall contain a budget for each Member Party’s out-of-pocket expenses for such Member Party’s activities set forth therein (respectively, the “U.S. Commercialization Budget” and “Canadian Commercialization Budget;” together, the “Commercialization Budgets”). The initial Commercialization Plan for each country covers (i) the [ * ] by each Member Party in [ * ] for the Initial Launch Period, (ii) [ * ] for the Combination Product in such country for the Initial Launch Period, and (iii) certain other Marketing and other commercialization activities for the Combination Product that are required to be conducted in such country by a single Member Party or that must be coordinated between the Member Parties. Updates of a Commercialization Plan shall not cover or include any activities not covered by the applicable initial Commercialization Plan unless mutually agreed by the Member Parties

(c) The responsible Member Party (as determined below) shall prepare and submit to each of the JCC or JCOC, as applicable, and JFC (i) not less than [ * ] prior to the start of each Calendar Year, any proposed update to a Commercialization Plan and a Commercialization Budget for such Calendar Year and (ii) not less than [ * ] prior to the start of each Calendar Year, a preliminary update to such Commercialization Budget (which may address budget issues at a general level, may be incomplete and is subject to change). Following review, discussion and revision of such proposed update, the JCC or JCOC, as applicable, shall vote upon such update at least [ * ] prior to the start of the applicable Calendar Year. BMS shall prepare the first such annual update; thereafter, such responsibility shall rotate between BMS and Gilead on a year-to-year basis, on the same annual schedule as for the first update, through the Calendar Year in which the Subsequent Launch Period for such country ends (or for such longer period as may be agreed by the Member Parties). In addition, either Member Party, directly or through its representatives on the JCC or JCOC, as the case may be, may propose interim updates to a Commercialization Plan and a Commercialization Budget to the JCC or JCOC from time to time as appropriate in light of changed circumstances. Such annual and interim updates for periods through the Calendar Year containing the end of the Subsequent Launch Period for such country shall be approved by the JCC as set forth in Section 2.4(b)(ii) or by the JCOC as set forth in Section 2.5(b)(ii), as applicable. Subject to Sections 2.2(vi) and 2.11, if a proposed update to the Commercialization Plan or Commercialization Budget is not approved by the JEC, then such Commercialization Plan or Commercialization Budget, as the case may be, shall continue in effect as approved and most recently updated pursuant to this Section 5.11(c).

5.12 Commercialization Expenses. The Parties agree that the JV shall bear all JV Expenses incurred by each of Gilead and BMS in connection with the performance of its respective Commercialization Activities with respect to a country in the Territory to the extent that they meet all of the following criteria (“Authorized Commercialization Expenses”): (a) such Commercialization Activities are covered in and consistent with the Commercialization Plan for such country and are within an area of responsibility for the relevant Member Party listed in the

-59-

applicable Commercialization Budget as being chargeable to the JV; (b) the total expenses for that Member Party’s designated activities under such Commercialization Plan for the relevant period do not exceed the aggregate amount set forth in the in the applicable Commercialization Budget for such activities in that period by more than [ * ] (c) the expenses are external, out-of-pocket costs of Gilead or BMS, without any markup, and not internal costs, including, without limitation, internal costs incurred in [ * ] and (d) the relevant Commercialization Activities are for the Marketing in such country of the Combination Product only and not for the Marketing of any other proprietary products of Gilead or BMS. Notwithstanding the limitation contained in clause (d) above, in the event that either Member Party reasonably believes that there are cost or other efficiencies that the JV can reasonably be expected to achieve through one or both Member Parties’ conducting Commercialization Activities with respect to the Combination Product as part of, or in coordination with, activities being conducted by one or both Member Parties with respect to its or their Single Agent Product(s) and/or Double Agent Product, such Member Party(ies) may propose, by and through its applicable Commercialization Committee member(s), that such activities be coordinated and an appropriate and reasonable allocation of the related costs be made between the Combination Product, on the one hand, and such other product or products, on the other hand, and that the amount allocated to the Combination Product be treated as Authorized Commercialization Expenses (each such proposal, a “Cost Allocation Proposal”). If, and only to the extent that, such Cost Allocation Proposal is reviewed by the JFC and JCC or JCOC, as applicable, pursuant to Sections 0 and 0 or 2.5(b)(vii), respectively, and approved by the JEC pursuant to Section 2.2(ix) (with any modifications made by the JEC), the amount approved by the JEC for allocation to the Combination Product (any such approved costs, “Allocated Costs”) shall constitute Authorized Commercialization Expenses.

5.13 Reports. Gilead and BMS shall each present to the other, at a meeting of the applicable Commercialization Committee at least once per Calendar Quarter until the second anniversary of the Launch of the Combination Product in the applicable country in the Territory and, thereafter, at a meeting of the applicable Commercialization Committee at least semiannually, a report (oral and written, which written report shall not be required to contain more detail than that typically included in an executive summary) describing (i) the Commercialization Activities it has performed, or caused to be performed, since the preceding meeting at which such a report was presented (or, in the case of the first meeting of the applicable Commercialization Committee, prior to such meeting) and on a Calendar Year-to-date basis, evaluating the work performed in relation to the goals and timeline of each Commercialization Plan, (ii) its Commercialization Activities in process and the future activities it expects to initiate during the then-current Calendar Year, as compared to each Commercialization Plan, and (iii) in the case of the written report the Authorized Commercialization Expenses incurred, and expected to be incurred, by such Member Party for the then-current Calendar Year, as compared to the applicable Commercialization Budget. In addition, Gilead and BMS shall report promptly to the JCC or JCOC through their respective committee members any material developments with respect to Commercialization Activities that they are responsible for performing under the Commercialization Plan. Notwithstanding anything contained in this Section 5.13 to the contrary, each Member Party’s reporting obligations under this Section 5.13 shall automatically be deemed to terminate with respect to any period in which there is not then in effect a Commercialization Plan and/or a Commercialization Budget.

SECTION 7.

PAYMENTS AND THIRD PARTY ROYALTIES

7.1 Payments to Member Parties.

(a) In consideration of the supply by Gilead and BMS to the JV of quantities of their respective active pharmaceutical ingredients for manufacture of non-clinical supply of the Combination Product pursuant to Section 4.2(c) and their respective Supply Agreements (and in consideration of the provision of certain services hereunder), and subject to adjustment pursuant to Section 7.1(d), the JV shall pay to Gilead the “Gilead Transfer Price” and to BMS Sub the “BMS Transfer Price” in accordance with this Section 7. For a given Calendar Year, pursuant to this Section 7.1, the JFC shall calculate (i) interim Gilead Transfer Prices per kilogram of TDF or FTC bulk active pharmaceutical ingredient respectively, i.e. the applicable Transfer Price in accordance with Annex K hereto per kilogram of bulk active pharmaceutical ingredient (each an “Interim Gilead Unit Transfer Price”) and (ii) an interim BMS Transfer Price per kilogram of EFV active pharmaceutical ingredient, i.e. the applicable Transfer Price in accordance with Annex K hereto per kilogram of EFV active pharmaceutical ingredient (the “Interim BMS Unit Transfer Price”), in each case based upon the respective Working Percentages calculated pursuant to Section 7.1(c)(i), the Estimated Net Selling Price of the Combination Product in the Territory determined by the JFC with respect to such Calendar Year pursuant to Section 7.1(c)(ii), and the relevant Target Yield for the active pharmaceutical ingredient calculated pursuant to Annex K hereto. The JFC shall then inform Gilead and BMS of their respective Interim Unit Transfer Prices pursuant to Section 7.1(c)(iii). Subject to the last sentence of Section 7.3(c), each of Gilead and BMS Sub shall use its then-current Interim Unit Transfer Price(s) in preparing an invoice for each shipment of bulk active pharmaceutical ingredients it makes pursuant to Section 4.2(c) and its Supply Agreement.

(b) The Actual Gilead Percentage and the Actual BMS Percentage for a particular Calendar Year shall be equal to one hundred percent (100%) multiplied by a fraction, the denominator of which is the sum of the Net Selling Prices of Truvada and Sustiva in the Territory during the relevant Calendar Year, and the numerator of which is:

for the Actual Gilead Percentage, the Net Selling Price of Truvada in the Territory during the relevant Calendar Year; and

-69-

for the Actual BMS Percentage, the Net Selling Price of Sustiva in the Territory during the relevant Calendar Year;

provided, however, that, without limitation of the obligations of the Member Parties under Section 5.3A(j) or 5.3B(f), for purposes of calculating the numerator and denominator of such fraction for both the Actual Gilead Percentage and the Actual BMS Percentage, any [ * ] in the Net Selling Price of Sustiva or Truvada for the relevant Calendar Year that [ * ] for the Calendar Year [ * ] shall be [ * ] and any such [ * ] shall not be [ * ] In the event of a termination of this Agreement, the effective date of which falls on a date other than December 31 of a Calendar Year, the determination of the Actual Percentages shall be based on the period from January 1 of such Calendar Year through the effective date of termination, instead of the entire Calendar Year; and the provisions of this Agreement shall apply, mutatis mutandis, to such period.

(c) The JFC shall determine the Member Parties’ Interim Unit Transfer Prices for each Calendar Year using the Member Parties’ respective Working Percentages, the Estimated Net Selling Price and the Target Yield, as follows:

On or before [ * ] BMS and Gilead shall agree in writing on the Working BMS Percentage and the Working Gilead Percentage for Calendar Year 2005 (which shall be equal to their respective Actual Percentages for Calendar Year 2004 using the relevant data for Calendar Year 2004 inclusive). For each subsequent Calendar Year, the respective Working Percentages shall equal the Actual BMS Percentage and the Actual Gilead Percentage, respectively, for the immediately preceding Calendar Year; provided, however, that, with respect to any Calendar Year, pending determination of the Actual Percentages for the immediately preceding Calendar Year, the Working Percentages for such immediately preceding Calendar Year shall remain in effect until such time as the Actual Percentages for such immediately preceding Calendar Year have been determined. On or before [ * ] BMS and Gilead shall agree in writing on the Target Yields for each of EFV, TDF and FTC for the Calendar Year 2005. For each subsequent Calendar Year, the relevant Target Yields for EFV, TDF and FTC shall be calculated pursuant to Section 7.1(d)(ii) and Annex K.

No later than [ * ] of each subsequent Calendar Year, the JFC shall determine the estimated Net Selling Price for the Combination Product in the Territory for such Calendar Year using only historical data (such amount for each Calendar Year, the “Estimated Net Selling Price”).

Using the Member Parties’ respective Working Percentages, the Estimated Net Selling Price in the Territory and the Target Yield for such Calendar Year, the JFC shall calculate each Member Party’s Interim Unit Transfer Price(s), in accordance with Annex K and shall so notify the Member Parties in writing no later than [ * ] days after the first day of the applicable Calendar Year. From and after the date on which a Member Party receives a notice from the JFC with respect to such Member Party’s respective Interim Unit Transfer Price(s) with respect to such Calendar Year, such amounts shall then be used by the Member Parties in invoicing the JV for the Transfer Price for shipments of bulk active pharmaceutical ingredients pursuant to Section 4.2(c) and the applicable Supply Agreement in such Calendar Year. Notwithstanding the foregoing, on a Calendar Quarter basis, the JFC shall recalculate the respective Interim Unit Transfer Prices (each, a “Recalculated Transfer Price”) in accordance with Annex K within [ * ]

-70-

after the end of [ * ] Such recalculation shall be made using the Working Percentages, Target Yield and updated Net Selling Prices as determined in Annex I for such [ * ] In the event that a particular Interim Unit Transfer Price is less than the Recalculated Transfer Price, the JV shall deliver a reconciliation statement to the applicable Member Party setting forth the difference in price multiplied by the quantity of active pharmaceutical ingredient the Member Party invoiced to the JV during such [ * ] In the event a particular Interim Unit Transfer Price is greater than the Recalculated Transfer Price, the JV shall deliver a reconciliation statement to the applicable Member Party setting forth the difference in price multiplied by the quantity of active pharmaceutical ingredient the Member Party invoiced to the JV during such [ * ] In each case, the relevant adjustment shall be addressed as part of the cash netting mechanism provided for in Section 4.1 of the Operating Agreement and shall be settled on the first Cash Netting Day following such recalculation. The Interim Unit Transfer Prices shall not be changed as a result of the recalculation mentioned above.

Following [ * ] the JV shall cause the Independent Accounting Expert to calculate (solely for planning, accounting and bookkeeping purposes of the Member Parties) the Actual Percentages for such [ * ] based on data as of [ * ] to be completed no later than [ * ] after [ * ] The Respective Percentages shall not be changed as a result of the recalculation mentioned above.

(d) Following the end of each Calendar Year, the JFC shall cause an independent Third Party accounting firm or consultant mutually agreed by the Member Parties (such agreed Third Party, the “Independent Accounting Expert”) to calculate the Actual Percentages for such Calendar Year and recalculate the Transfer Prices (using the Product Yields determined pursuant to Section 7.1(d)(ii) and actual Net Selling Price for the Combination Product determined pursuant to Section 7.1(d)(iii)) with respect to shipments of bulk active pharmaceutical ingredient made by the Member Parties in such Calendar Year pursuant to Section 4.2(c) and their respective Supply Agreements, as follows.

Within [ * ] following the end of each Calendar Year, each Member Party shall provide to the Independent Accounting Expert the data necessary in order to make the calculations required pursuant to this Section 7.1(d), which data is described in Annex N.

Within [ * ] following the end of each Calendar Year, the JFC shall (A) calculate the Product EFV Yield, Product FTC Yield, and Product TDF Yield, in each case based on Actual Yield, for the supply of Combination Product and (B) provide to the Independent Accounting Expert written confirmation of such calculations. Within [ * ] following the first full-scale commercial manufacturing run, the JFC shall determine a blended average of each of Product EFV Yield, Product FTC Yield and TDF Product Yield on a per weight and per unit basis and inform the Independent Accounting Expert thereof.

Within [ * ] following the end of each Calendar Year, the JV shall cause the Independent Accounting Expert to (A) calculate the actual Net Selling Prices of the Combination Product, Truvada and Sustiva for that Calendar Year, (B) calculate the Actual Gilead Percentage and the Actual BMS Percentage pursuant to Section 7.1(b) using the actual Net Selling Prices of the Combination Product, Truvada and Sustiva for that Calendar Year and (C) recalculate the Gilead Transfer Price and the BMS Transfer Prices for the bulk active pharmaceutical ingredient shipments during that Calendar Year pursuant to Section 7.1(a) in accordance with Annex K.

Within [ * ] following the end of each Calendar Year, on the basis of such the recalculated Transfer Prices (as notified to the JV by the Independent Accounting Expert), the JFC shall

-71-

recalculate the amounts owed by the JV to the Member Parties with respect to shipments received by the JV in such Calendar Year pursuant to Section 4.2(c) and their respective Supply Agreements and provide to the Member Parties notice of the recalculated amounts (and the adjustments that will be required pursuant to this Section 7.1(d)(iv)). If the aggregate amount invoiced by a Member Party for Transfer Prices is greater than or less than the aggregate amount owed to such Member Party by the JV for such Transfer Prices, as recalculated pursuant to this Section 7.1(d), then the relevant adjustment shall be addressed as part of the cash netting mechanism provided for in Section 4.1 of the Operating Agreement and shall be settled on the first Cash Netting Day following such recalculation.

(e) The Independent Accounting Expert shall be bound by commercially reasonable written confidentiality and non-use obligations to the Member Parties. Such Independent Accounting Expert shall, upon the written request of either Member Party (the “Initiating Member”), audit the other Member Party to confirm the accuracy of the data provided to such Independent Accounting Expert by such other Member Party. Further, upon the written request of either Member Party, the calculations of the Independent Accounting Expert shall be audited by a second Third Party mutually agreed by the Member Parties. The Independent Accounting Expert and the Third Party auditor, if any, shall notify the Member Parties of their respective determinations; provided, however, that neither the Independent Accounting Expert nor any Third Party selected to audit the Independent Accounting Expert shall share with either Member Party any information provided to such Independent Accounting Expert (and/or such Third Party) by the other Member Party. The calculations made by the Independent Accounting Expert pursuant to this Section 7.1(e) shall be binding on the Parties; provided, however, that in the event that a Third Party auditor identifies a discrepancy in the Independent Accounting Expert’s calculations, the Member Parties shall cause the Independent Accounting Expert and such Third Party to confer and agree upon the final calculations and advise the Member Parties in writing of same, whereupon such final agreed calculations shall be binding on the Parties. The Initiating Member shall bear the fees and costs of the Independent Accounting Expert in connection with its confirmation of the accuracy of such data, unless the Independent Accounting Expert finds a discrepancy equal to or greater than [ * ] therein, in which case the other Member Party shall bear such fees and costs.

(f) For the purpose of making calculations under this Agreement that require conversion from Canadian dollars into U.S. dollars, the Member Parties shall convert Canadian Dollars into U.S. dollars according to the following rules:

For the purpose of calculating the Net Selling Price for the Combination Product as it relates to the applicable Transfer Price, during a given Calendar Year, in Canadian dollars, the applicable Member Party shall convert such Canadian dollars to US dollars using the applicable spot rate listed on [ * ] to be determined by the JFC, which date shall occur within [ * ] after the approval by the JEC of the annual update to the Canadian Commercialization Budget for such Calendar Year.

For all purposes other than calculating the Net Selling Price for the Combination Product as it relates to the applicable Transfer Price, including for calculating the Net Selling Price of Viread, Emtriva, Truvada and Sustiva sold in Canadian dollars and for calculating Authorized Expenses incurred in Canadian dollars, each Member Party shall, in a manner consistent with its then-

-72-

current standard worldwide currency conversion methodology, convert the applicable amounts incurred or sold, as the case may be, in Canadian dollars into US dollars.

7.2 Royalty Payments to Third Parties. If a Third Party’s Patent is or would be infringed or a Third Party’s trade secrets are or would be misappropriated solely as a direct result of the incorporation of TDF, FTC or both TDF and FTC in the Combination Product, then Gilead shall be solely responsible for any Losses or royalty, license fee or other payment obligation to such Third Party (which shall not qualify as a JV Expense or Authorized Expense) in connection with such infringement or misappropriation, including, without limitation, its obligations pursuant to Section 11.4. If a Third Party’s Patent is or would be infringed or a Third Party’s trade secrets are or would be misappropriated solely as a direct result of the incorporation of EFV in the Combination Product, then BMS shall be solely responsible for any Losses or royalty, license fee or other payment obligation to such Third Party (which shall not qualify as a JV Expense or Authorized Expense) in connection with such infringement or misappropriation, including, without limitation, its obligations pursuant to Section 11.4. All other royalty, license fee or other payments by Gilead or BMS to Third Parties in connection with licenses under Third Party Patents or Third Party trade secrets which are reasonably necessary for the performance of the Member Parties’ obligations under this Agreement shall qualify as Authorized Commercialization Expenses.

7.3 Authorized Expenses; Mode and Timing of Payment.

(a) The JV shall bear all Authorized Expenses incurred by Gilead and BMS. Each Member Party shall calculate and invoice the JV for its respective Authorized Expenses incurred in each Calendar Quarter in sufficient time to ensure that the applicable invoice is received by the JV no later than the last day of the next Calendar Quarter (the “Final Invoice Date”). The JV shall not have any obligation to make payments to Gilead or BMS on account of any such expenses incurred in a given Calendar Quarter for which an invoice is not received by the Final Invoice Date.

(b) All payments by the JV to the Member Parties pursuant to Sections 7.3(a) and 14.6(b)(ii) and other payments to be made to Member Parties under this Agreement shall be made by wire transfer or electronic funds transfer of United States Dollars in the requisite amount to such bank account as each Member Party may designate from time to time by notice to the payor.

(c) Each Member Party shall calculate and invoice the JV at the time of shipment, for the Transfer Price for each shipment of bulk active pharmaceutical ingredient pursuant to Section 4.2(c) and the applicable Supply Agreement using the applicable Interim Unit Transfer Price. The JV shall pay to a Member Party any amounts owed to such Member Party (or, in the case of BMS, to BMS Sub) pursuant to Section 7.1(a) on the applicable Cash Netting Day as provided in Section 4.1 of the Operating Agreement. In the case of any shipment of bulk active pharmaceutical ingredient pursuant to the applicable Supply Agreement during the first Calendar Quarter of a given Calendar Year prior to the JFC giving notice of the applicable Interim Unit Transfer Price, the Member Party providing such shipment shall use the Interim Unit Transfer Price for the immediately preceding Calendar Year for purposes of invoicing such shipment, provided that upon the JFC’s determination of the new Interim Xxxx

-00-

Transfer Price for the Calendar Year in which such shipment occurs pursuant to Section 7.1(d) and Annex K, the JV shall recalculate such invoices using such new Interim Transfer Price for such Calendar Year and at the time of payment shall issue to the applicable Member Party a reconciliation statement, with respect to such invoice to reconcile any differences between the original Transfer Price for such shipment and the Transfer Price for such shipment as calculated using such new Interim Unit Transfer Price.

(d) Interest shall accrue on delinquent payments from the date such payments are due at the lesser of (i) the prime rate of interest, as published in The Wall Street Journal (Eastern United States Edition), plus [ * ] basis points and (ii) the maximum rate of interest permissible under Applicable Law, taking into consideration any amounts deemed additional interest.

(c) The Member Parties may, for commercial reasons or otherwise, mutually determine to withdraw the Combination Product from the market. If the reason for market withdrawal relates to efficacy or safety, such withdrawal shall be treated as one mandated by a government agency or authority and be dealt with as provided in Section 10.1(b). In all other cases, the JV shall, upon receiving Regulatory Authority approval, cease selling the Combination Product; and the Member Parties shall mutually determine whether, and if so how, to recall any Combination Product already on the market.

(d) Nothing set forth in this Section 10.1 shall be construed as restricting the right of either Member 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.

10.2 Recall Expenses. The Member Parties shall bear the expenses of any recall of the Combination Product in proportion to their Respective Percentages, and their respective external, out-of-pocket costs of such recall (without any markup) shall qualify as an Authorized Other Expense; provided, however, that each Member Party shall bear the expenses of a recall incurred in a reasonable manner to the extent that such recall is (a) caused by such Member Party’s breach of its obligations under this Agreement or its Supply Agreement (or, if it is the Supplier, its supply contract referred to in Section 4.2) or its gross negligence or willful misconduct, or (b) otherwise occasioned solely by such Member Party’s Single Agent Product and/or Double Agent Product, as the case may be. Such expenses of recall shall include, without limitation, the expenses of notification and destruction or return of the recalled Combination Product and the refund to consumers of amounts paid for the recalled Combination Product.

In the event that the Member Parties fail to reach written agreement that such patent application should be filed, neither Member Party, whether on behalf of itself, the JV or any Third Party, may file or cause to be filed such patent application.

In the event that the Member Parties mutually agree in writing pursuant to Section 11.2(c)(i) that a patent application for a Joint Patent claiming a Joint Invention should be filed, Gilead shall have the sole right and obligation to prepare, file, prosecute and maintain the Joint Patents in the name of the JV in such countries as the Member Parties shall determine, and the external, out-of-pocket costs, without any markup, with respect thereto shall be treated as Authorized Other Expenses. BMS shall cooperate fully in Gilead’s preparation, filing, prosecution, and maintenance of the Joint Patents (and in any other proceedings before a patent official or office with respect thereto). Such cooperation shall include, without limitation, (A) promptly executing all papers and instruments or requiring employees to execute such papers and instruments as reasonable and appropriate so as to enable Gilead to prepare, file, prosecute, and maintain the Joint Patents in any country; and (B) promptly informing Gilead of matters that may affect the preparation, filing, prosecution, or maintenance of any such Joint Patent, including, without limitation, providing a copy of any official correspondence received by BMS from a patent office in any country with respect to Joint Patents. Gilead shall keep BMS advised of the status

-78-

of Joint Patent filings and upon request of BMS 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.

The Member Parties shall have the sole discretion to determine (by mutual agreement) which Joint Patents, if any, shall be listed in the “Orange Book” [ * ] with respect to the Combination Product.

11.3 Enforcement of Patents.

(a) Gilead Patents. As among the Parties, Gilead shall have the sole right and option, at its sole cost and expense, to respond to any Infringement (as defined below) with respect to any Gilead Patent by appropriate steps, including, without limitation, by filing an infringement suit or taking other similar action. Gilead shall also have the sole right and option not to take action to respond to any such Infringement (and in such event no other Party shall have the right to take any action to respond to any Infringement with respect to such Gilead Patent). At Gilead’s request, each of BMS and the JV shall, at such Party’s own expense, provide reasonable assistance to Gilead in connection with any such action to respond to Infringement, including, without limitation, providing access to relevant documents and other evidence, making its employees available at reasonable business hours, and joining (and having the JV join) the action to the extent necessary to allow Gilead to maintain the action. For purposes of this Section 11.3, (i) “Infringement” shall mean (A) infringement or potential infringement of one (1) or more Gilead Patents and/or one (1) or more BMS Patents, as the case may be, by the actions of a Third Party in connection with a product (an “Infringing Combination Product”) containing, among its active pharmaceutical ingredients, all of TDF, FTC and EFV and/or (B) with respect to Canada, [ * ] with respect to the Combination Product and (ii) “other similar action” shall include, without limitation, responses to paragraph (iv) certification under the Drug Price Competition and Patent Restoration Act (also known as the Xxxxx-Xxxxxx Act) (a “Paragraph (iv) Certification”) and actions under section 6 of the Patented Medicines (Notice of Compliance) Regulations (Canada) resulting from an attempt to market a Generic Version Combination Product. For the avoidance of doubt, the Parties acknowledge and agree that infringement of a Gilead Patent or a BMS Patent, as the case may be, other than by an Infringing Combination 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.

(b) BMS Patents. As among the Parties, BMS shall have the sole right and option, at its sole cost and expense, to respond to any Infringement with respect to any BMS Patent by appropriate steps, including, without limitation, filing an infringement suit or taking other similar action. BMS shall also have the sole right and option not to take action to respond to any such Infringement (and in such event no other Party shall have the right to take any action to respond to any Infringement with respect to a BMS Patent). At the request of BMS, each of Gilead and the JV shall, at such Party’s own expense, provide reasonable assistance to BMS or the EFV Licensor as applicable, in connection with any such action to respond to Infringement including, without limitation, providing access to relevant documents and other evidence, making its employees available at reasonable business hours, and joining (and having the JV join) the action to the extent necessary to allow BMS or the EFV Licensor to maintain the action.

-79-

(c) Joint Patents. If either Member Party determines that any Joint Patent is being infringed by a Third Party’s activities, it shall notify the other Member Party in writing and provide it with any evidence of such infringement that is reasonably available. Gilead, on behalf of, and in the name of, the JV, shall have the first right and option to respond to any infringement with respect to any Joint Patent by appropriate steps, including without limitation, filing an infringement suit or taking other similar action, and shall notify BMS of, and consult with BMS from time to time regarding, any such suit or other action. If Gilead elects at its sole discretion not to take action to respond to any such infringement, then BMS, on behalf of, and in the name of, the JV, shall have the right and option to respond to such infringement by appropriate steps, including without limitation, filing an infringement suit or taking other similar action, and shall notify Gilead of, and consult with Gilead from time to time regarding, any such suit or other action. Without limiting the foregoing, in the event that Gilead (for itself or on behalf of the JV) receives a Paragraph (iv) Certification [ * ] with respect to the Combination Product, Gilead shall notify BMS within thirty (30) days after its receipt of such Paragraph (iv) Certification [ * ] whether or not Gilead has made the election described in the preceding sentence and, if Gilead elects not to take action to respond to any such infringement, or fails to notify BMS within such [ * ] period, then BMS shall have the rights described in the immediately preceding sentence. The Member Party not taking action to respond to the infringement shall provide reasonable assistance to the Member Party taking such action, including without limitation 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 Member Party taking such action to maintain the action. Any amounts recovered by a Member Party pursuant to this Section 11.3(c), whether by settlement or judgment, shall be deemed to be recovered on behalf of (and shall be paid over to) the JV; and the reasonable out-of-pocket costs, including reasonable attorneys’ fees, without any markup, incurred by the Member Parties in making such recovery shall be treated as Authorized Other Expenses.

(d) Paragraph (iv) Certifications; [ * ] Each Member Party shall notify the other Member Party in writing within [ * ] of receiving any Paragraph (iv) Certification [ * ] with respect to the Combination Product, (in the case of BMS) Sustiva, or (in the case of Gilead) Viread, Emtriva or Truvada, as applicable.

11.4 Infringement of Third Party Rights. If a Third Party initiates a Proceeding against the JV or a Member Party alleging that the conduct of the Project Activities infringes or will infringe such Third Party’s Patent or misappropriates or will misappropriate such Third Party’s trade secrets, (a) if such Proceeding arises as a direct result of TDF, FTC or both TDF and FTC being incorporated in the Combination Product, in each case without reference to EFV, then Gilead shall defend and hold the JV and BMS harmless from and against such Proceeding and any Losses resulting from such Proceeding, and shall have the sole right and obligation to defend such Proceeding or to settle it (e.g., by obtaining a license from such Third Party) at Gilead’s sole cost (which shall not be deemed a JV Expense or Authorized Expense), and BMS shall reasonably cooperate at Gilead’s request and expense in such defense and/or settlement; (b) if such claim arises as a direct result of EFV being incorporated in the Combination Product, in each case without reference to TDF or FTC, then BMS shall defend and

-80-

hold the JV and Gilead harmless from and against such Proceeding and any Losses resulting from such Proceeding, and shall have the sole right and obligation to defend such Proceeding or to settle it (e.g., by obtaining a license from such Third Party) at BMS’ sole cost (which shall not be deemed a JV Expense or Authorized Expense), and Gilead shall reasonably cooperate at BMS’ request and expense in such defense and/or settlement; and (c) in the event that neither clause (a) nor (b) applies, then the JEC shall determine whether to defend against such claim or to obtain a license from such Third Party, and if so, on what terms and conditions (which out-of-pocket costs, without any markup, shall be deemed Authorized Other Expenses), and which Member Party shall take such actions on behalf of the JV. The procedures set forth in Section 13.8 shall apply to indemnification of Member Parties under this Section 11.4.

11.5 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 by appropriate steps, including, without limitation, 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 or take action to respond to any such infringement.

(b) BMS Licensed Trademarks. BMS shall have the sole right, at its sole cost and expense, to search, clear, file, register, prosecute, maintain and enforce the BMS Licensed Trademarks in the Territory. BMS shall have the sole right and option, at its sole cost and expense, to respond to any infringement with respect to any BMS Licensed Trademark by appropriate steps, including, without limitation, by filing an infringement suit or taking other similar action. BMS shall also have the sole right and option not to prosecute, maintain or enforce BMS Licensed Trademarks or take action to respond to any such infringement.

(c) Combination Product Trademarks. Except as otherwise expressly provided in Section 6.7, the Parties agree that, as among themselves, the JV shall own all right, title and interest in and to the Combination Product Trademarks. Gilead shall be solely responsible for searching, clearing, filing, registering, prosecuting and maintaining the Combination Product Trademarks in the Territory in the name of the JV, the external out-of-pocket costs (without any markup) of which shall be treated as Authorized Other Expenses. If either Member Party has a reasonable basis to believe that a Third Party is or may be engaging in commercially significant infringement of any Combination Product Trademark, such Member Party shall notify the other Member Party in writing and provide it with any evidence of such infringement that is reasonably available. Gilead shall have the first right and option to respond to any infringement or potential infringement with respect to any Combination Product Trademark by appropriate steps, including, without limitation, filing an infringement suit or taking other similar action, and shall notify BMS of, and consult with BMS from time to time regarding, any such suit or other action. If Gilead elects at its sole discretion not to take action to respond to any such infringement or potential infringement within [ * ] of Gilead’s becoming aware of such infringement or potential infringement, then BMS shall have the right and option

-81-

to respond to such infringement or potential infringement by appropriate steps, including, without limitation, filing an infringement suit or taking other similar action, and shall notify Gilead of, and consult with Gilead from time to time regarding, any such suit or other action. The Member Party not taking action to respond to the infringement or potential infringement shall provide reasonable assistance to the Member Party taking such action, including, without limitation, 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 Member Party taking such action to maintain the action. Any amounts recovered by a Member Party pursuant to this Section 11.5(c), whether by settlement or judgment, shall be deemed to be recovered on behalf of (and shall be paid over to) the JV; and the reasonable out-of-pocket costs, including reasonable attorneys’ fees, without any markup, incurred by the Member Parties in making such recovery shall be treated as Authorized Other Expenses.

(a) Made only as required to specific persons or entities under applicable laws, rules, regulations or orders of a court of competent jurisdiction or other supra-national, federal, national, regional, state, provincial or local governmental or regulatory body of competent jurisdiction; provided, however, that the Receiving Party shall first have given notice to the Disclosing Party and given the Disclosing Party a reasonable opportunity to seek any available limitations on, exemptions from or protections available under such disclosure requirement and reasonably cooperate in any such efforts by the Disclosing Party; and provided further that if an exemption from such disclosure requirement is not obtained, the Confidential Information disclosed in response to such requirement shall be limited to that information which is legally required to be disclosed;

(a) Defined. “Confidential Information” of a Party shall mean the terms of this Agreement and all Information and Inventions provided by or on behalf of such Party to another Party (or, in the case of Section 5.3A, to the US Pricing Committee) either in connection with the discussions and negotiations pertaining to this Agreement (including under the Mutual Confidential Disclosure Agreement entered into by and between Xxxxxxx-Xxxxx Squibb Company and Gilead Sciences, Inc. as of December 12, 2003) or in the course of performing this Agreement or the MTTA, including, without limitation: the material terms of this Agreement; 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.

(b) Exclusions. Notwithstanding the foregoing, Information and Inventions of a Disclosing Party shall not be deemed Confidential Information with respect to a Receiving Party for purposes of this Agreement if it:

was already known to the Receiving Party or its Affiliates, other than under an obligation of confidentiality or non-use, at the time of disclosure to such Receiving Party;

was generally available or known, or was otherwise part of the public domain, at the time of its disclosure to such Receiving Party;

became generally available or known, or otherwise became part of the public domain, after its disclosure to such Receiving Party through no fault of the Receiving Party or its Affiliates;

was disclosed to such Receiving Party or its Affiliates, other than under an obligation of confidentiality or non-use, by a Third Party who had no obligation to the Disclosing Party not to disclose such Information and Inventions to others; or

was independently discovered or developed by such Receiving Party or its Affiliates, as evidenced by their written records, without the use of Confidential Information belonging to 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 merely because the Confidential Information is embraced by more general information in the public domain or in the possession of such Party. Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of a Party merely because individual elements of such Confidential Information are in the public domain or in the possession of such Party unless the combination and its principles are in the public domain or in the possession of such Party.

-84-

12.4 Use of Name. Subject to Sections 5.8, 6.7 and 12.5, no Member Party shall mention or otherwise use the name, insignia, symbol, trademark, trade name or logotype of another 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 Member Party in each instance. For purposes of this Section 12.4, Approved Marketing Materials shall be deemed to have been approved by all of the Member Parties. The restrictions imposed by this Section shall not prohibit any Member Party from making any disclosure identifying another Party that is required by Applicable Law.

(b) After public disclosure of the joint press release pursuant to Section 12.5(a), if either Member Party desires to make a public announcement (such as a press release) concerning the material terms of this Agreement, such Member Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Member Party for its prior review and approval (except as otherwise provided in this Section 12.5(b)), such approval not to be unreasonably withheld. A Member Party commenting on such a proposed announcement shall provide its comments, if any, as soon as reasonably practicable but in any event within three (3) Business Days after receiving the proposed announcement for review. Either Member Party shall have the right to make a press release announcing the receipt of Approvals, subject only to the review procedure set forth in the preceding sentence. Neither Member Party shall be required to seek the permission of the other Member Party to repeat any information as to the terms of this Agreement that have already been publicly disclosed by such Member Party in accordance with Section 12.2 or this Section 12.5. In the event of a legally required press release or other public announcement or disclosure, the Member Party in question shall provide the other Member Party with a copy of the proposed text with as much notice as practicable (which shall be no less than three (3) Business Days prior to the proposed disclosure), the other Member Party shall respond with its comments as promptly as practicable (but no less than one (1) Business Day prior to the proposed disclosure), and the Member Party in question shall take into due consideration any and all reasonable comments that such other Member Party may provide in a timely manner; provided, however, that if a Member Party determines that it must make a legally required disclosure under Regulation FD, then it shall have the right to make such disclosure at such time as is necessary to comply with Regulation FD and shall provide the other Member Party with as much notice and opportunity for review and comment as is practicable in the circumstances.

12.6 Notification. The Receiving Party shall notify the Disclosing Party immediately, and cooperate with the Disclosing Party as the Disclosing Party may reasonably request, upon the Receiving Party’s discovery of any loss or compromise of the Disclosing Party’s Confidential Information.

12.7 Permitted Uses. Notwithstanding any provision of this Agreement to the contrary, regardless of which Member Party is the Disclosing Party, to the extent that any Confidential Information relates specifically to the Combination Product, including any such Confidential Information consisting of Combination Product Regulatory Documentation, each Member Party shall have the right to use such Confidential Information in connection with any Exploitation of the Combination Product to the extent permitted by the terms and conditions of this Agreement, including, without limitation (a) any use in accordance with the license grants made by the JV to the Member Parties in Section 6.2, or with the Rights of Reference granted by the JV to the Member Parties in Sections 6.4(b), 6.4(c) and 6.4(d), as the case may be, or (b) in connection with the preparation and/or submission to Regulatory Authorities as required in connection with any filing or application, or request for regulatory approval for the Combination Product anywhere in the world.

12.8 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 represent an insufficient remedy. In the event of any violation of this Section 12, 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, and may obtain that relief without making a showing of insufficiency of money damages or irreparable harm. The Receiving Party agrees to waive any requirement that the Disclosing Party post bond as a condition for obtaining any such relief.

The BMS Patents are not subject to any encumbrance or lien by any Third Party (except for any such encumbrances or liens as would not, in the aggregate, have a material adverse effect on the license rights granted to the JV and Gilead under this Agreement). Prior to the Effective Date, BMS has delivered to Gilead a copy (with financial terms redacted) of any license or similar grant of rights between BMS, on the one hand, and a Third Party, on the other hand, (i) pursuant to which BMS obtained from such Third Party a license or other rights with respect to any of the BMS Patents, or (ii) pursuant to which BMS grants to any such Third Party a license or other rights with respect to any of the BMS Patents for Exploitation in the Territory.

BMS shall use commercially reasonable efforts to maintain its Single Agent Product label and the BMS 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 BMS makes the representation and covenant to Gilead set forth in this Section 13.2(e) solely for purposes of the Member Parties’ collaboration pursuant to this Agreement, and for no other purpose.

(b) Neither Gilead nor any of its Affiliates has been debarred or is subject to debarment and neither Gilead nor any of its Affiliates shall use in any capacity, in connection with the services to be performed under this Agreement, any Person who has been debarred pursuant to Section 306 of the Act, or who is the subject of a conviction described in such section. Gilead agrees to inform BMS in writing immediately if it or any Person who is performing services under this Agreement is debarred or is the subject of a conviction described in Section 306, or if any action, suit, claim, investigation or legal or administrative proceeding is pending or, to the knowledge of Gilead, is threatened, relating to the debarment or conviction of Gilead or any Person performing services under this Agreement.

(c) Gilead has the right to grant the license under the Gilead Patents that is set forth in Section 6.1(a), and has not, prior to the Effective Date, made a grant to any Third Party of any right or license in respect of the Gilead Patents that would conflict with any grant of rights or licenses to BMS or the JV hereunder. The Gilead Patents are not subject to any encumbrance or lien by any Third Party (except for any such encumbrances or liens as would not, in the aggregate, have a material adverse effect on the license rights granted to the JV and BMS under this Agreement). Prior to the Effective Date, Gilead has delivered to BMS a copy (with financial terms redacted) of any license or similar grant of rights between Gilead, on the one hand, and a Third Party, on the other hand, (i) pursuant to which Gilead obtained from such Third Party a license or other rights with respect to any of the Gilead Patents, or (ii) pursuant to which Gilead grants to any such Third Party a license or other rights with respect to any of the Gilead Patents for Exploitation in the Territory. Gilead covenants and agrees that, except for agreements referred to in the preceding sentence (including extensions, amendments and renewals thereof), it shall not, from and after the Effective Date and throughout the term of this Agreement, grant to any Third Party any right or license in respect of the Gilead Patents that would conflict with any grant to Gilead or the JV hereunder.

-89-

(d) There are no judgments or settlements against or amounts with respect thereto owed by Gilead relating to the Gilead Patents. To the knowledge of Gilead, it has not received written notice of any Proceeding in which it is alleged that (i) the Gilead 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 EFV, infringes any Third Party Patent.

(e) 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 and NDSs 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 as of the Effective Date. Gilead shall use commercially reasonable efforts to maintain its Single and Double Agent Product labels and the Gilead Regulatory Documentation through updates as needed to ensure that such information continues to represent a complete and accurate reflection in all material respects of the safety and efficacy profile of its Single and Double Agent Products. It is understood and agreed that Gilead makes the representation and covenant to BMS set forth in this Section 13.3(e) solely for purposes of the Member Parties’ collaboration pursuant to this Agreement, and for no other purpose.

(f) Quantities of FTC and TDF provided by Gilead pursuant to Section 4.1 will (i) be Manufactured using reasonable care; (ii) conform to the applicable Product Specifications (as defined in the Gilead Supply Agreement) and with the applicable certificate of analysis at the time of delivery; (iii) be conveyed by Gilead with good title and free from any lawful security interest, lien or encumbrance; and Gilead (or any Affiliates or Third Party suppliers as applicable) will have obtained all approvals required by all applicable Regulatory Authorities to Manufacture FTC and TDF for use in Viread, Emtriva and Truvada as applicable.

13.8 Indemnification Procedure.

(a) Each Indemnified Party agrees to give the Indemnifying Party prompt written notice of any Losses or the discovery of a fact (including any Proceeding) upon which such Indemnified Party intends to base a request for indemnification under Section 11.4, 13.5, 13.6 or 13.7, as the case may be (it being understood and agreed, however, that the failure to give notice as provided in this Section 13.8(a) shall not relieve the Indemnifying Party of any such indemnification obligations except and only to the extent that the Indemnifying Party is actually materially prejudiced as a result of such failure to give notice).

(b) Each Party shall furnish promptly to the other Parties, copies of all papers and official documents received in respect of any Proceedings. The Indemnified Party shall reasonably cooperate as requested by and at the expense of the Indemnifying Party in the defense of any Proceedings.

(c) With respect to any Losses relating solely to the payment of money damages and which shall not result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affecting the Indemnified Party in any manner, and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party under this Agreement, the Indemnifying Party shall have the sole right to defend, settle or otherwise dispose of such Proceeding, on such terms as the Indemnifying Party shall deem appropriate.

(d) With respect to all Losses other than those addressed in Section 13.8(c), and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party under this Agreement, the Indemnifying Party

-93-

shall have the sole right to control the defense of the relevant Proceeding, provided that the Indemnifying Party shall obtain the written consent of the Indemnified Party, which shall not be unreasonably withheld, prior to ceasing to defend, settling or otherwise disposing of any Proceeding if as a result thereof (i) the Indemnified Party would become responsible for the payment of any money damages or other costs (with respect to which the Indemnifying Party has contested or challenged or may contest or challenge its obligation to indemnify), (ii) the Indemnified Party would become subject to injunctive or other equitable relief or any remedy other than the payment of money by the Indemnifying Party or (iii) the Indemnified Party would otherwise be adversely affected.

(e) Furthermore, with respect to each of Section 13.8(c) and 13.8(d), the Indemnifying Party shall be entitled to control the proceeding only if it so notifies the Indemnified Party within thirty (30) days after delivery of the notice by the Indemnified Party under Section 13.8(a).

(f) The Indemnifying Party shall not be liable for any Losses resulting from any settlement or other disposition of a Proceeding by the Indemnified Party which is reached without the written consent of the Indemnifying Party.

(g) The allocation among the Member Parties and the JV of any liability for a Loss or Proceeding, if not otherwise determined in a court of law, shall be considered by the JEC and, if the JEC does not reach agreement on such allocation, by unanimous Member Vote or unanimous written consent of its members, either Member Party shall have the right to refer the dispute to arbitration pursuant to Section 15.6. The dispute resolution procedures in Section 2.8 shall not apply to any disputes arising under this Section 13.8(g).

13.9 Limitation on Damages. Except for breaches of Section 12, the Parties shall not be liable to each other for special, indirect, incidental or consequential damages (including, without limitation, for lost profits), whether in contract, warranty, negligence, tort, strict liability or otherwise, arising out of any breach or failure to perform any provision(s) of this Agreement; provided, however, that the Parties shall be liable to each other for [ * ] and provided, further, that the Parties shall be liable to each other for [ * ] provided that such breaches are intentional or arise out of acts or omissions constituting gross negligence. Nothing in this Section 13.9 is intended to or shall operate to limit a Party’s obligations of indemnity with respect to losses awarded to third parties in a proceeding under Sections 11.4, 13.5, 13.6 and 13.7.

13.10 Ancillary Agreements. Any reference in this Agreement to an Ancillary Agreement (other than the SDEA) or any obligation under any such Ancillary Agreement, shall

-94-

not be construed to include within the scope of the indemnification obligations of the Parties under this Agreement any liability arising out of any such Ancillary Agreement or any obligation under any such Ancillary Agreement.

13.11 Employees. The Parties agree that, as among the Parties, all actions taken or omitted to be taken by any employee of a Member Party (or any of its Affiliates) in his or her capacity as a member of the JEC, any Operating Committee or the US Pricing Committee, and all other actions taken or omitted to be taken by any employee of a Member Party (or any of its Affiliates) with respect to the Project Activities, shall be attributed only to such Member Party. Accordingly, any claims by the other Member Party or the JV arising out of such actions or inactions shall be asserted directly against the Member Party who is (or whose Affiliate is) such individual’s employer, and such other Member Party, or the JV, as the case may be, hereby waives any such claims against such individual.

SECTION 14.

TERM AND TERMINATION

14.1 Term. The term of this Agreement shall commence as of the Effective Date and shall continue until terminated by mutual agreement of the Parties or otherwise in accordance with this Section 14.

14.2 Certain Litigation. This Agreement shall terminate upon notice given by either Member Party to the other Member Party in the event that any U.S. governmental authority seeks or obtains a temporary restraining order or preliminary injunction to enjoin the transactions contemplated by this Agreement or institutes litigation seeking other relief in respect of such transactions under any Applicable Law in the United States.

14.3 Termination with respect to Canada.

(a) Either Member Party may terminate this Agreement, solely as to Canada, by notice to the other Member Party if either (i) no NDS for the Combination Product in the Field is filed by [ * ] or (ii) no NDS for the Combination Product in the Field is approved by [ * ]

(b) This Agreement shall terminate with respect to Canada upon notice given by either Member Party to the other Member Party in the event that any [ * ] under any Applicable Law in Canada.

14.4 Material Default.

(a) If a Member Party (the “Breaching Member Party”) fails to comply with or perform, in any material respect, any of its material obligations contained in this Agreement or the Operating Agreement, or any act or omission by such Member Party causes a failure by the JV to comply with or perform, in any material respect, any of its material obligations contained in this Agreement or the Operating Agreement (any such default, a

-95-

“Material Default”), then the other Member Party (the “Non-Breaching Member Party”) shall have the right to give to the Breaching Member Party notice specifying the nature of the Material Default. The Breaching Member Party shall have a period of sixty (60) days after receipt of such notice to fully cure the Material Default in a manner reasonably acceptable to the Non-Breaching Member Party, and, if it does not do so within such period, the Member Parties shall discuss in good faith appropriate adjustments to or cancellation of the Member Parties’ respective obligations under this Agreement to permit the continuation of this Agreement and the JV on a mutually agreeable basis. For the avoidance of doubt, the Non-Breaching Member Party may, in its sole discretion, deliver a notice of Material Default to the Breaching Member Party prior to completion of the dispute resolution procedures set forth in Section 2.9, in which case the sixty (60) day cure period referred to in the preceding sentence shall begin to run upon receipt of such notice and shall run concurrently with such procedures.

(b) If the Breaching Member Party does not cure a Material Default pursuant to Section 14.4(a) and the Member Parties’ discussions pursuant to the last sentence of Section 14.4(a) do not lead to a mutually agreeable restructuring of this Agreement, then if the Non-Breaching Member Party and the Breaching Member Party mutually agree that it is both desirable and practicable to withdraw the Combination Product from the market in the Territory, the Non-Breaching Member Party shall have the right to terminate this Agreement as a whole upon notice to the Breaching Member Party given within thirty (30) days of the cessation of the Member Parties’ discussions pursuant to the last sentence of Section 14.4(a). Any such termination shall be effective upon such withdrawal, and the Member Parties shall cooperate with each other and cause the JV to effect such withdrawal as promptly as practicable under Applicable Law.

(c) Whether or not there is a termination of this Agreement pursuant to Section 14.4(b), the Non-Breaching Member Party shall have the right to seek damages on account of the Material Default in an arbitration pursuant to Section 15.6. The express remedies of the Non-Breaching Member Party pursuant to this Section 14.4 shall be in addition to any other remedies in favor of the Non-Breaching Member Party (or, if applicable, the JV) provided for in this Agreement or the Operating Agreement, as applicable, or under the BMS Guarantee Agreement or Gilead Guarantee Agreement, as applicable.

(d) The Parties acknowledge that each Member Party has entered into this Agreement and the Operating Agreement in reliance on the other Member Party’s continued compliance with, and performance of, its obligations under this Agreement and the Operating Agreement. Accordingly, each Member Party agrees that any Material Default may cause severe and irreparable damage to the Non-Breaching Member Party or the JV as applicable, for which money damages would represent an insufficient remedy. In the event of any such Material Default, notwithstanding anything in this Agreement to the contrary, the Non-Breaching Member Party shall be authorized and entitled to seek from any arbitrator under Section 15.6 the remedy of specific performance with respect to any such Material Default, as well as any other relief permitted by Applicable Law and may obtain that relief without making a showing of the insufficiency of money damages. The Breaching Member Party agrees to waive any requirement that the Non-Breaching Member Party post bond as a condition for obtaining any such relief.

-96-

14.5 Termination Upon Generic Launch [ * ] Either Member Party (the “Continuing Member Party”) may terminate this Agreement [ * ] by notice to the other Member Party (the “Terminated Member Party”) in the event that there is the Launch in the [ * ] of at least one (1) Generic Version of all of the Single Agent Products (or the Double Agent Product) of the Terminated Member Party (a “Generic Version Launch”) and the Continuing Member Party delivers notice of termination within thirty (30) days after the Generic Version Launch. Such termination shall be effective on the last day of the Calendar Quarter in which such notice is given. For the avoidance of doubt, [ * ]

Each such payment shall be accompanied by a written report, providing a detailed breakdown of the calculation of amounts paid for the relevant period.

The Terminated Member Party, at its own election (of which it shall promptly notify the Continuing Member Party in writing), shall (pursuant to a license and/or supply agreement containing the following terms and any other terms upon which the Member Parties mutually agree) either (A) enable the Continuing Member Party to Manufacture quantities of EFV or TDF and FTC, as the case may be, in bulk active pharmaceutical ingredient form for use in the Manufacture of the Combination Product for use in the Territory, in which event the Terminated Member Party shall (1) automatically be deemed to grant a royalty-free, non-exclusive license to the Continuing Member Party (or its Third Party designee, which shall be reasonably acceptable to the Terminated Member Party) under the Terminated Member Party’s Patents covering such Manufacture and Information and Inventions used in such Manufacture by or on behalf of the Terminated Member Party, to Manufacture such ingredient(s) for the sole purpose of using such ingredient(s) in the Manufacture of the Combination Product for the Territory, and (2) provide reasonable technical assistance to such Continuing Member Party or Third Party designee (which choice of recipient shall be subject to the prior approval of the Terminated Member Party, such approval not to be unreasonably withheld or delayed), at the Continuing Member Party’s expense on the Terminated Member Party’s then-current standard terms and conditions; or (B) continue

The JV and the Continuing Member Party shall be responsible for all Third Party royalties payable by the Terminated Member Party in respect of any supply provided by the Terminated Member Party pursuant to this Section 14.6(b)(iii).

effective date of such termination (i) the Territory shall exclude Canada, (ii) the obligations of the Parties with respect to the development and commercialization of the Combination Product in Canada, including without limitation obtaining and maintaining any Approvals for the Combination Product in Canada, shall cease, including without limitation any obligations under the Canadian Commercialization Plan or any Development Activities with respect to Canada as set forth in the Development Plan with respect to Canada attached hereto as Annex V, (iii) the JCOC shall cease to operate, and (iv) each Member Party shall promptly (and in any event within [ * ] thereafter) make arrangements for the return or disposal, at the other Member Party’s option, of any Confidential Information relating solely to Canada, 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 the licenses and other rights granted in Section 6). Such termination shall not effect any other provisions of this Agreement, which shall remain in effect.

14.7 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by the JV, BMS or Gilead are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the United States Bankruptcy Code. The Parties agree that the JV, BMS and Gilead, as licensees of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the United States Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against the JV or either Member Party under the United States Bankruptcy Code, the non-subject Parties shall be entitled to a complete duplicate of (or complete access to, as the non-subject Party deems appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in their possession, shall be promptly delivered to them (a) upon any such commencement of a bankruptcy proceeding upon a non-subject Party’s written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement or (b) if not delivered under clause (a) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by a non-subject Party. The provisions of this Section 14.7 are without prejudice to any rights the non-subject Parties may have arising under the U.S. Bankruptcy Code or other Applicable Law.

(a) Termination or expiration of this Agreement in its entirety or with respect to either country in the Territory shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to such termination or expiration.

SECTION 15.

GENERAL PROVISIONS

15.1 Force Majeure. No Party shall be held liable or responsible to the other Parties or 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, without limitation, 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 Parties of such force majeure within five (5) days after such occurrence by giving written notice to the other Parties 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 Collaboration Principles. For purposes of this Agreement a force majeure shall not include a failure to commit sufficient resources, financial or otherwise, to the Project Activities or general market or economic conditions.

15.3 Further Assurances. Each Party shall 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, without limitation, the filing of such assignments, agreements, documents and instruments, as may be necessary or as another Party may reasonably request in connection with this Agreement or 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.

15.4 Successors and Assigns.

(a) 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 3.5, 4.1, 4.2 and 5.5, no Member Party may, without the prior written consent of the other Member Party, assign or otherwise transfer any of its rights and interests or subcontract or otherwise delegate any of its obligations under this Agreement; provided, however, that (i) either Member Party, without such consent, may assign its rights and

-102-

delegate its duties under this Agreement to an Affiliate which is a directly or indirectly wholly-owned subsidiary of Gilead Parent or BMS Parent, as the case may be; provided, however, that the assigning Member Party shall remain primarily (and not secondarily or derivatively) liable for the full and timely performance by such Affiliate of all its obligations under this Agreement; and provided, further, that, except as set forth in clause (ii) below, such assignment or delegation shall terminate automatically at such time, if any, as such Affiliate ceases to be wholly-owned, directly or indirectly, by Gilead Parent or BMS Parent, as the case may be, and (ii) either Member Party, without such consent, may assign its rights and delegate its duties under this Agreement, whether by contract or operation of law, to a Third Party Acquirer in the event of a Change of Control of such Member Party. Any permitted successor or assignee of rights and/or obligations hereunder (a “Permitted Assignee”) shall, in a writing delivered to the other Parties at the time of such assignment, expressly assume performance of such rights and/or obligations. The JV may not assign this Agreement without the prior written consent of the Member Parties. Any purported assignment, transfer, subcontract or delegation by either Member Party or the JV in violation of the terms of this Section 15.4 shall be null and void and of no legal effect.

(b) In the event of any Change of Control of a Member Party (the “Transferring Member Party”), the Transferring Member Party shall give the other Member Party written notice thereof within ten (10) days, identifying such Third Party Acquirer. If at the time of such Change of Control such Third Party Acquirer is marketing in the Territory a Competing Product that was commercially available as of the Effective Date, then upon written notice from the other Member Party at its election to the Transferring Member Party within thirty (30) days of such other Member Party’s receiving written notice of such Change of Control, such Third Party Acquirer shall have [ * ] If such Third Party Acquirer fails to [ * ] (i) the performance obligations (other than payment obligations) of the Member Parties under this Agreement shall terminate, except to the extent of those minimum obligations reasonably required (A) for the JV to obtain and maintain Approval for the Combination Product in the Territory, (B) for Gilead, to sell the Combination Product on behalf of the JV, to perform its obligations with respect to pricing and discounting of the Combination Product pursuant to Section 5.3A, the [ * ] Section 5.3B and the [ * ] and (C) for each Member Party to supply to the JV bulk active pharmaceutical ingredient pursuant to Section 4 and the applicable Supply Agreement, (ii) the Commercialization Plan and Budget (including any minimum Commercialization expenditures and/or [ * ] shall terminate, and (iii) each Member Party shall have the right to Promote, Market and otherwise commercialize the Combination Product in the Territory without coordination with the other Member Party under this Agreement (including, without any obligation to reach agreement on the form of Approved Marketing Materials).

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

15.6 Arbitration.

(a) Disputes between the Member Parties, or between a Member Party and the JV, relating to or arising out of the validity, interpretation or construction of, or the compliance with or breach of, this Agreement, the Operating Agreement, any Ancillary

-103-

Agreement or any other agreement contemplated by this Agreement to which such Member Party (or its Affiliates) and the JV and/or the other Member Party (or its Affiliates) are parties shall (except as otherwise expressly provided in this Agreement, the Operating Agreement, any Ancillary Agreement or any such other agreement) be referred initially to the JEC as provided in Section 2.8 and, if not resolved as so provided in Section 2.8, thereafter (subject to the limitations in Section 2.8) resolved exclusively through binding arbitration in accordance with the CPR Institute for Dispute Resolution Rules for Non-Administered Arbitration, to be held in Washington, D.C. In any proceeding between a Member Party and the JV, the other Member Party shall act on behalf of and in the name of the JV, and any external, out-of-pocket costs (without markup) so incurred by such other Member Party shall be deemed to be JV Expenses and Authorized Expenses. In any proceeding under this Section 15.6, there shall be one arbitrator, except that at the election of either Member Party in writing within ten (10) Business Days of receiving notice of such referral to arbitration, there shall be a panel of three (3) arbitrators. The Member Parties shall appoint such arbitrator(s) by mutual agreement or, if the Member Parties cannot agree on the appointment of such arbitrator(s) within thirty (30) days after receipt of a demand for arbitration, the Member Parties shall have the relevant number of arbitrators with the required qualifications appointed by the CPR Institute for Dispute Resolution, provided that if either Member Party has elected to have a panel of three arbitrators, each Member Party shall have the right to appoint one arbitrator with the required qualifications, and the third arbitrator shall be appointed by the CPR Institute for Dispute Resolution. Each arbitrator shall either have at least ten (10) years of significant management level experience in the biopharmaceutical industry including responsibility for legal matters or have at least ten (10) years of substantial experience as an attorney representing or working with biopharmaceutical clients as either in-house or outside counsel in commercial litigation or transactional matters, shall not be directly or indirectly affiliated with either Member Party or with either Member Party’s Affiliates, and shall not have any direct or indirect interest of any kind in the resolution of the relevant issue. This Section 15.6 shall also apply to any dispute properly referred to arbitration in accordance with Section 2.8 or Section 13.8(g) hereof or Section 6.5(d) of the Operating Agreement (with respect to the JEC).

(b) Any fees and expenses payable with respect to an arbitration under this Section 15.6, together with the reasonable legal fees of the prevailing Party, shall be borne by the non-prevailing Party, as determined by the arbitrator(s). All arbitration rulings and awards shall be final and binding on the Parties.

(c) Any dispute referred to binding arbitration pursuant to this Section 15.6 shall be scheduled for discovery, briefing and arguments by the arbitrator(s) so that the decision can be rendered within [ * ] (or as soon thereafter as practicable) after such referral. Each of the Member Parties shall submit to the arbitrator(s) a comprehensive proposal for resolution of the dispute (including, if the arbitration involves an allegation of breach by a Member Party of any of its obligations under this Agreement, the Operating Agreement, any Ancillary Agreement or any other agreement contemplated by this Agreement to which such Member Party (or its Affiliates) and the JV and/or the other Member Party (or its Affiliates) are parties, a proposal for damages), and the arbitrator(s) shall decide in favor of one of the two (2) proposals, without making any modifications thereto. The decision of the arbitrator(s) shall be

-104-

based on which of the proposals complies most nearly with this Agreement, any relevant Development Plan(s) or Commercialization Plan(s), and any relevant principles reflected in such plans, including, without limitation, the Collaboration Principles.

(d) Nothing in this Agreement, including, without limitation this Section 15.6, shall preclude either Member 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 Member Party, either prior to or during the dispute resolution procedures set forth in this Section 15.6, if necessary to protect the interests of such Member Party. This Section 15.6(d) shall be specifically enforceable.

15.7 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.

15.8 Severability. If any provision of this Agreement, other than the obligation of the JV to make payments pursuant to Section 7.1(a), should be held 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 their best 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. 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.

15.9 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.

15.10 Construction. Except where the context otherwise requires, wherever used the singular shall include the plural, the plural the singular, 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 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 Member Parties, or words of similar import, shall not be construed as an agreement that the Member 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 any Party.

-105-

15.11 Status of the Parties. Except as set forth expressly in this Agreement or in the Operating Agreement, no Party shall have the right to enter into any agreements or take action on behalf of any other Party, nor shall it represent to any Person that it has any such right or authority. Except for the status of BMS Sub and Gilead Sub as members of the JV, nothing in this Agreement shall be construed as establishing a partnership or joint venture relationship between the Parties. Each Member Party shall be made a third party beneficiary of all Ancillary Agreements to which the other Member Party is a party, for the purpose of enforcing the JV’s rights thereunder.

15.12 Standstill. During the period commencing on the Effective Date and continuing until the fifth anniversary of the Effective Date, BMS shall not, and shall cause the Affiliates of BMS not to:

(a) acquire, or offer or agree to acquire, directly or indirectly, beneficial ownership of any equity securities of Gilead, or any rights or options to acquire such beneficial ownership, or otherwise act in concert with respect to any such securities, rights or options with any Person;

(b) make, or participate in, directly or indirectly, any “solicitation” of “proxies” to vote (as such terms are used in the Regulation 14A promulgated under the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”)), become a “participant” in any “election contest” (as such terms are defined in Rule 14a-11 promulgated under the Exchange Act) or initiate, propose or otherwise solicit stockholders of Gilead for the approval of any stockholder proposals;

(c) form, join, participate in, or encourage the formation of, a group (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any voting securities of Gilead;

(d) deposit any securities of Gilead into a voting trust, or subject any securities of Gilead to any agreement or arrangement with respect to the voting of such securities;

(e) make any public announcement with respect to, or submit a proposal for, or offer (with or without conditions) of any extraordinary transaction involving Gilead or any of its securities or assets;

(f) seek, or encourage or support any effort, to influence or control the management, Board of Directors, business, or policies of Gilead (it being understood and agreed that this Section 15.12(f) shall not apply to the exercise by BMS of any of its rights and obligations under this Agreement, the Operating Agreement and the Ancillary Agreements as applicable);

(g) encourage or assist any other Person to undertake any of the foregoing actions; or

-106-

(h) take any action that could reasonably be expected to require Gilead to make a public announcement regarding the possibility of any of the events described in clauses (a) through (g) of this Section 15.12;

provided, however, that nothing in Sections 15.12(a), (e) or (g) shall be deemed to prohibit BMS from acquiring (i) by merger or stock purchase of more than fifty percent (50%) of the voting securities thereof, a Third Party that has beneficial ownership of equity securities of Gilead (or rights or options to acquire such beneficial ownership) or (ii) beneficial ownership of up to five percent (5%) of any class of equity securities of Gilead (or rights or options to acquire such beneficial ownership) by or through (1) an employee benefit plan of BMS or any of its Affiliates, (2) a diversified mutual or pension fund managed by an independent investment adviser or pension plan established for the benefit of the employees of BMS or its Affiliates, or (3) any stock portfolios not controlled by BMS or any of its Affiliates that invest in Gilead or any of its Affiliates among other companies; provided that BMS or any of its Affiliates does not, directly or indirectly, request the trustee or administrator or investment adviser of such fund, plan or portfolio to acquire Gilead equity securities; and provided, further, that this Section 15.12 shall be of no further effect and shall not bind BMS in any manner from and after such time, if any, as Gilead shall make a public announcement that it has entered into a letter of intent or definitive agreement with a Third Party Acquirer providing for a Change of Control of Gilead.

15.13 Nonsolicitation of Employees. During the period commencing on the Effective Date and continuing through the term of this Agreement, each Member Party agrees that neither it nor any of its Affiliates that participates in or is responsible for the Development or Commercialization of the Combination Product pursuant to this Agreement shall recruit, solicit or induce any employee of the other Member Party’s, or any of its Affiliates’, HIV/Virology Sales Force (including managers) who is employed in the Territory to terminate his or her employment with such other Member Party or its Affiliate and become employed by or consult for such other Member Party or its Affiliate, whether or not such employee is a full-time employee of such other Member Party or its Affiliate, and whether or not such employment is pursuant to a written agreement or is at-will. For purposes of the foregoing, “recruit,” “solicit” or “induce” shall not be deemed to mean (x) general solicitations by Third Party placement specialists or firms (e.g., headhunters) or (y) other general solicitations of employment (including responses to general advertisements), in each case ((x) and (y)) not specifically targeted at employees of a Party or any of its Affiliates.

15.14 Entire Agreement. This Agreement (including the Annexes hereto), together with the Operating Agreement, the Ancillary Agreements and the other agreements contemplated by this Agreement (including without limitation the SDEA), constitutes, on and as of the Amended Effective Date, the entire agreement of the Parties with respect to the subject matter hereof, and all prior or contemporaneous understandings or agreements, whether written or oral, between the Parties with respect to such subject matter (including the Mutual Technology Transfer Agreement entered into by Xxxxxxx-Xxxxx Squibb Company and Gilead Sciences, Inc. as of February 5, 2004 (the “MTTA”) and the Mutual Confidential Disclosure Agreement entered into by and between Xxxxxxx-Xxxxx Squibb Company and Gilead Sciences, Inc. as of December 12, 2003, as amended) are hereby superseded in their entireties; provided,

-107-

however, that any rights and obligations of the Parties under the MTTA and such Mutual Confidential Disclosure Agreement that have accrued as of the Effective Date shall survive. This Agreement shall not be amended in any respect whatsoever except by a further agreement, in writing, fully executed by each of the Parties (or prior to the Effective Date, by Gilead and BMS). Amendment of this Agreement shall be without prejudice to any rights that shall have accrued to the benefit of a Party hereunder prior to such amendment.

15.15 Consent to Jurisdiction. Each Party, for the purpose of enforcing an award under Section 15.6 or for seeking injunctive or other equitable relief as permitted by Section 12.8, 14.4(d) or 15.6(d), (a) irrevocably submits to the non-exclusive jurisdiction of the United States District Court for the District of Columbia (the “Court”), for purposes of any action, suit or other proceeding arising out of this Agreement, the Operating Agreement and any Ancillary Agreement, and (b) agrees not to raise any objection at any time to the laying or maintaining of the venue of any such action, suit or proceeding in any of 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 or 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 15.15.

15.16 Third Parties. Except as set forth in Sections 13.5, 13.6, and 13.7 as to those Third Parties expressly referred to therein, the agreements, covenants and representations contained herein are for the benefit of the Parties only and are not for the benefit of any Third Parties.

Annex I – Manner of Calculation of Net Selling Price

The Net Selling Price for a product for a relevant period for a country shall be expressed in dollars per daily dose for such product and shall be equal to the quotient of (i) the aggregate Net Sales for such country of such product for such period that are recognized as revenue (under United States generally accepted accounting principles in effect from time to time, as consistently applied), divided by (ii) the number of daily doses of such product in units for which revenue may be recognized (under United States generally accepted accounting principles in effect from time to time, as consistently applied) for such period that may be sold or used [ * ] in such country plus the number of daily doses of such product in [ * ] for such country shipped during such period, provided, however, that consistent with the definition of Net Sales, [ * ]. The Parties’ intent is that the practices of BMS and Gilead in calculation of Net Sales shall be harmonized in the process of calculating Net Selling Price, such that (a) any deductions, payments, rebates or other compensations made or given by BMS or Gilead in connection with or in respect of sales of such products shall be treated as a deduction from gross amount invoiced in the calculation of Net Sales, and (b) if both BMS and Gilead make payments or provide other compensation for a similar purpose with respect to a product but only one of them treats that item for accounting purposes as a deduction from revenues, then for purposes of calculation of Net Selling Price under this Annex I that item shall be a deduction from gross amount invoiced in the calculation of Net Sales for both parties.

XXXXXXX-XXXXX SQUIBB AND GILEAD SCIENCES ESTABLISH

JOINT VENTURE TO DEVELOP AND COMMERCIALIZE

FIXED-DOSE COMBINATION OF THREE HIV MEDICINES

First Collaboration to Develop a Once-Daily Antiretroviral Fixed-Dose Regimen

Xxx Xxxx, XX xxx Xxxxxx Xxxx, XX, DATE, 2004 – Xxxxxxx-Xxxxx Squibb Company (NYSE: BMY) and Gilead Sciences, Inc. (Nasdaq: GILD) today announced details of a joint venture to develop and commercialize the fixed-dose combination of Xxxxxxx-Xxxxx Squibb’s Sustiva^® (efavirenz) and Gilead’s Truvada^™ (emtricitabine and tenofovir disoproxil fumarate) in the United States. If approved, the new product would be the first complete Highly Active Antiretroviral Therapy (HAART) treatment regimen for HIV available in a fixed-dose combination taken once daily. Fixed-dose combinations contain multiple medicines formulated together and may help simplify HIV therapy for patients and providers. The joint venture established by the two companies is the first of its kind in the field of HIV therapy.

The work necessary to co-formulate Sustiva and Truvada into a once-daily combination product has been ongoing throughout most of 2004 and will continue into 2005. Through the joint venture – Xxxxxxx-Xxxxx Squibb & Gilead Sciences, LLC – the companies will work in partnership to complete development and U.S. regulatory filings for this fixed-dose regimen. Subject to receiving marketing approval of the fixed-dose regimen, the companies would share responsibility for commercializing the product in the United States. Both companies will provide funding and field-based sales representatives in support of promotional efforts for the combination product. Xxxxxxx-Xxxxx Squibb and Gilead will receive revenues from future net sales at percentages relative to the contribution represented by their individual products that comprise the fixed-dose combination.

Guidelines issued by the U.S. Department of Health and Human Services (DHHS) list the combination of emtricitabine, tenofovir disoproxil fumarate and efavirenz as one of the preferred non-nucleoside reverse transcriptase inhibitor (NNRTI)-based treatments for use in appropriate patients that have never taken anti-HIV medicines before. It is important that patients be aware that individual HIV medications must be taken as part of combination regimens, and that they do not cure HIV infection or prevent passing HIV to others.

“Gilead and Xxxxxxx-Xxxxx Squibb share a steadfast commitment to addressing the needs of people living with HIV/AIDS around the world, and today’s announcement signals significant progress toward our common goal,” commented Xxxx X. Xxxxxx, PhD, president and chief executive officer, Gilead Sciences. “This landmark partnership reflects the dedication Gilead and Xxxxxxx-Xxxxx Squibb bring to delivering simplified therapy to physicians and patients. We look forward to working with the Xxxxxxx-Xxxxx Squibb team to ensure this novel therapeutic advancement reaches physicians and people living with HIV/AIDS as rapidly as possible.”

“For more than a decade, Xxxxxxx-Xxxxx Squibb has been a leader in the field of HIV with significant investments in innovative scientific research and an unwavering commitment to finding new and better treatment options to help improve the lives of people with HIV,” said Xxxxx X. Xxxxx, chairman and chief executive officer, Xxxxxxx-Xxxxx Squibb Company. “We are pleased to be leveraging our leadership in HIV through this collaboration with Gilead to help advance the management of the disease through the development of potentially more convenient treatment options.”

Earlier in 2004, U.S. Secretary of Health and Human Services Xxxxx Xxxxxxxx addressed the need for new products to help advance and simplify treatment for people with HIV/AIDS, encouraging members of industry to work together to create fixed-dose combinations that would help achieve these goals. Additionally, earlier this year the U.S. Food and Drug Administration issued new guidelines to expedite the approval of new combination products for HIV.

“The availability of simplified treatment regimens for HIV/AIDS is important to our ability to make progress in the fight against the disease,” Secretary Xxxxxxxx said. “I am pleased to see the collaboration and efforts of Xxxxxxx-Xxxxx Squibb and Gilead. This partnership to create a fixed-dose combination of three HIV medications represents an important advance in our collective effort to deliver simplified therapy for people living with HIV.”

Important Safety Information About Sustiva

Sustiva is a prescription medicine used in combination with other medicines to treat people who are infected with the human immunodeficiency virus type 1 (HIV-1). Sustiva does not cure HIV or help prevent passing HIV to others.

Sustiva should not be taken with Hismanal^® (astemizole), Propulsid^® (cisapride), Versed^® (midazolam), Halcion^® (triazolam), ergot medicines (for example, Wigraine^® and Cafergot^®), or Vfend^® (voriconazole). This list of medicines is not complete. Patients should discuss all prescription and non-prescription medicines, vitamin and herbal supplements, or other health preparations (particularly St. John’s wort) they are taking or plan to take with their healthcare provider. Patients taking Sustiva should tell their doctor right away if they have any side effects or conditions including: severe depression, strange thoughts, or angry behavior, which have been reported in a small number of patients. A few reports of suicide have been made, but it is not known if Sustiva was the cause. Patients should tell their doctor if they have a history of mental illness or are using drugs or alcohol. Dizziness, trouble sleeping, drowsiness, trouble concentrating, and/or unusual dreams are common. These feelings tend to go away after taking Sustiva for a few weeks.

Women should not become pregnant or breastfeed while taking Sustiva. Rash is a common side effect that usually goes away without any change in treatment. Rash may be a serious problem in some children. If a child develops a rash, their doctor should be contacted right away. Patients should tell their

L-2

doctor if they have liver disease, have ever had seizures, or are taking medicine for seizures as tests to check the liver or drug levels in the blood may be needed. Changes in body fat have been seen in some patients taking HIV medicines, however, the cause and long-term effects of these changes are not known at this time. Other common side effects include: tiredness, upset stomach, vomiting and diarrhea. Taking Sustiva with food increases the amount of medicine in the body, which may increase the frequency of side effects. Sustiva should be taken on an empty stomach, preferably at bedtime, which may make some side effects less bothersome. United States Full Prescribing Information is available at xxx.xxxxxxx.xxx.

About Truvada

Truvada combines Emtriva^® (emtricitabine) and Viread^® (tenofovir disoproxil fumarate) in one tablet taken once a day in combination with other antiretroviral agents. In the United States, Truvada is indicated in combination with other antiretroviral agents (such as non-nucleoside reverse transcriptase inhibitors or protease inhibitors) for the treatment of HIV-1 infection in adults. Safety and efficacy studies using Truvada tablets or using Emtriva and Viread in combination are ongoing.

Both components of Truvada have been studied individually, as part of multi-drug regimens and have been found to be safe and effective. Since Emtriva and lamivudine (3TC) are comparable in their structure, resistance profiles, and efficacy and safety as part of multi-drug regimens, existing data from the use of lamivudine and Viread in combination have been extrapolated to support use of Truvada tablets for the treatment of HIV-1 infection in adults. Therefore, in treatment-naïve patients, Truvada should be considered as an alternative to the combination of Viread and lamivudine for those patients who might benefit from a once-daily regimen. In treatment-experienced patients, the use of Truvada should be guided by laboratory testing and treatment history.

There are no study results demonstrating the effect of Truvada on clinical progression of HIV-1, and it is not recommended that Truvada be used as a component of a triple nucleoside regimen.

Truvada should not be used with Emtriva or Viread, or other drugs containing lamivudine, including Combivir^®, Epivir^®, Epivir-HBV^®, Epzicom^™ or Trizivir^®. Two-hundred eighty-three patients have received combination therapy with Emtriva and Viread with either a non-nucleoside reverse transcriptase inhibitor or protease inhibitor for 24 to 48 weeks in ongoing clinical studies. Based on these limited data, no new patterns of adverse events were identified and there was no increased frequency of established toxicities. For additional safety information about Emtriva or Viread in combination with other antiretroviral agents, please see “About Emtriva” and “About Viread,” below.

Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues alone or in combination with other antiretrovirals. Viread, Emtriva and Truvada are not indicated for the treatment of chronic hepatitis B virus (HBV) infection and the safety and efficacy of these drugs has not been established in patients co-infected with HBV and HIV. Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued Viread or Emtriva. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue Viread, Emtriva or Truvada and are co-infected with HIV and HBV. If appropriate, initiation of anti-hepatitis B therapy may be warranted.

Changes in body fat have been observed in patients taking Viread, Emtriva, Truvada and other anti-HIV medicines. The cause and long term health effect of these conditions are unknown.

L-3

About Viread

In the United States, Viread is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection. This indication is based on analyses of plasma HIV-1 RNA levels and CD4 cell counts in controlled studies of Viread in treatment-naïve adults and in treatment-experienced adults. There are no study results demonstrating the effect of Viread on clinical progression of HIV-1. The use of Viread should be considered for treating adult patients with HIV-1 strains that are expected to be susceptible to tenofovir as assessed by laboratory testing or treatment history.

Drug interactions have been observed when didanosine, atazanavir or lopinavir/ritonavir is co-administered with Viread and dose adjustments may be necessary. Data are not available to recommend a dose adjustment of didanosine for patients weighing less than 60 kg. Patients on atazanavir or lopinavir/ritonavir plus Viread should be monitored for Viread-associated adverse events which may require discontinuation. When co-administered with Viread, it is recommended that atazanavir 300 mg be given with ritonavir 100 mg. Atazanavir without ritonavir should not be co-administered with Viread.

Renal impairment, including serious cases, has been reported. Renal impairment occurred most often in patients with underlying systemic or renal disease or in patients taking concomitant nephrotoxic agents, though some cases have appeared in patients without identified risk factors. Decreases in bone mineral density (BMD) at the lumbar spine and hip have been seen with the use of Viread. The clinical significance of changes in BMD and biochemical markers is unknown and follow-up is continuing to assess long-term impact. The most common adverse events and those occurring in more than 5 percent of patients receiving Viread with other antiretroviral agents in clinical trials include asthenia, pain, abdominal pain, headache, nausea, diarrhea, vomiting, rash (rash, pruritis, maculopapular rash, urticaria, vesiculobullous rash and pustular rash), flatulence, dizziness and depression. Less than 1 percent of patients discontinued participation because of gastrointestinal events.

About Emtriva

In the United States, Emtriva is indicated, in combination with other antiretroviral agents, for the treatment of HIV-1 infection in adults. This indication is based on analyses of plasma HIV-1 RNA levels and CD4 cell counts from controlled studies of 48 weeks duration in antiretroviral-naïve patients and antiretroviral-treatment-experienced patients who were virologically suppressed on an HIV treatment regimen. In antiretroviral-treatment-experienced patients, the use of Emtriva may be considered for adults with HIV strains that are expected to be susceptible to Emtriva as assessed by genotypic or phenotypic testing.

Adverse events that occurred in more than 5 percent of patients receiving Emtriva with other antiretroviral agents in clinical trials include abdominal pain, asthenia (weakness), headache, diarrhea, nausea, vomiting, dizziness and rash (rash, pruritis, maculopapular rash, urticaria, vesiculobullous rash, pustular rash and allergic reaction). Approximately 1 percent of patients discontinued participation because of these events. All adverse events were reported with similar frequency in Emtriva and control treatment groups with the exception of skin discoloration which was reported with higher frequency in the Emtriva treated group. Skin discoloration, manifested by hyperpigmentation on the palms and/or soles, was generally mild and asymptomatic. The mechanism and clinical significance are unknown.

XXXXXXX-XXXXX SQUIBB AND GILEAD SCIENCES ESTABLISH AGREEMENT

TO COMMERCIALIZE ATRIPLA^™ (efavirenz 600 mg/ emtricitabine 200 mg/ tenofovir

disoproxil fumarate 300 mg) IN CANADA

If Approved, Product Would Be the First Once-Daily Single Tablet Regimen for HIV-1 Infection in Adults in Canada

Princeton, N.J. and Foster City, Calif., September 28, 2006 – Xxxxxxx-Xxxxx Squibb Company (NYSE: BMY) and Gilead Sciences, Inc. (Nasdaq: GILD) today announced an agreement to commercialize ATRIPLA^TM(efavirenz 600 mg/ emtricitabine 200 mg/ tenofovir disoproxil fumarate 300 mg) in Canada for the treatment of HIV-1 infection in adults, subject to the approval of the product by Health Canada. ATRIPLA is the first once-daily single tablet regimen (STR) for HIV intended as a stand-alone therapy or in combination with other antiretrovirals. ATRIPLA received approval from the U.S. Food & Drug Administration on July 12, 2006.

The agreement is the result of negotiations between Xxxxxxx-Xxxxx Squibb and Gilead Sciences and expands the companies’ U.S. joint venture established in December 2004. The companies will work together to complete regulatory filings in Canada and will share responsibility for commercializing ATRIPLA in Canada, subject to regulatory approval of the product. As in the United States, both companies will provide funding and field-based sales representatives in support of promotional efforts for ATRIPLA. Gilead will record revenues from future net sales of ATRIPLA, while Xxxxxxx-Xxxxx Squibb will record revenues at percentages relative to the contribution represented by its individual product.

“We are pleased to have finalized our agreement for Canada, and are working expeditiously to complete the regulatory filing for ATRIPLA with Health Canada,” said Xxxx X. Xxxxxx, PhD, President and CEO, Gilead Sciences. “We recognize the need for access to ATRIPLA, the first once-daily single tablet regimen, and are working to make it available to all patients who need it as quickly as possible.”

W-3

“This agreement with Gilead Sciences marks an important step forward in our efforts to deliver effective HIV therapies,” said Xxxxxxxx Xxxxxxxxx, president, Worldwide Pharmaceuticals, Xxxxxxx-Xxxxx Squibb. “We look forward to working with Gilead Sciences and Health Canada to make available another effective treatment option for Canadian adult patients living with HIV/AIDS.”

ATRIPLA combines SUSTIVA^® (efavirenz), manufactured by Xxxxxxx-Xxxxx Squibb, and Truvada^® (emtricitabine and tenofovir disoproxil fumarate), manufactured by Gilead Sciences. Truvada itself is a fixed-dose product that contains two of Gilead’s anti-HIV medications, Viread^{^®} (tenofovir disoproxil fumarate) and Emtriva^{^®} (emtricitabine), in a single once-daily tablet for use as part of combination therapy.

Important Safety Information About ATRIPLA, Truvada, Viread and Emtriva

Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues alone or in combination with other antiretrovirals. ATRIPLA, Truvada, Viread and Emtriva are not indicated for the treatment of chronic hepatitis B virus (HBV) infection and the safety and efficacy of these drugs have not been established in patients co-infected with HBV and HIV. Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued Emtriva or Viread (components of ATRIPLA and Truvada). Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue ATRIPLA, Truvada, Emtriva or Viread and are co-infected with HIV and HBV. If appropriate, initiation of anti-hepatitis B therapy may be warranted.

Additional Important Information About ATRIPLA

In the United States, ATRIPLA is indicated for use alone as a complete regimen or in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults.

It is important for patients to be aware that ATRIPLA does not cure HIV infection or AIDS. ATRIPLA has not been shown to reduce the risk of transmission of HIV to others through sexual contact or blood contamination.

ATRIPLA is contraindicated for use with astemizole, cisapride, midazolam, triazolam, ergot derivatives, or voriconazole. Concomitant use of ATRIPLA and St. John’s wort (Hypericum perforatum) or St. John’s wort-containing products is not recommended. Since ATRIPLA contains efavirenz, emtricitabine and tenofovir disoproxil fumarate, it should not be coadministered with SUSTIVA, Emtriva, Viread, or Truvada. Due to similarities between emtricitabine and lamivudine, ATRIPLA should not be coadministered with drugs containing lamivudine, including Combivir^®, Epivir^®, Epivir-HBV^®, Epzicom^™, or Trizivir^®.

W-4

medication. There have been occasional postmarketing reports of suicide, delusions, and psychosis-like behavior, but it could not be determined if efavirenz was the cause. Patients with serious psychiatric adverse experiences should be evaluated immediately to determine whether the risks of continued therapy outweigh the benefits. Fifty-three percent of patients reported central nervous system symptoms including dizziness (28.1%), insomnia (16.3%), impaired concentration (8.3%), somnolence (7.0%), abnormal dreams (6.2%) and hallucinations (1.2%) when taking efavirenz compared to 25% of patients receiving control regimens. These symptoms usually begin during the first or second day of therapy and generally resolve after the first two to four weeks of therapy. After four weeks of therapy, the prevalence of central nervous system symptoms of at least moderate severity ranged from 5% to 9% in patients treated with regimens containing efavirenz. Nervous system symptoms are not predictive of the less frequent psychiatric symptoms.

ATRIPLA should not be given to patients with creatinine clearance below 50 mL/min. Renal impairment, including cases of acute renal failure and Fanconi syndrome (renal tubular injury with severe hypophosphatemia), has been reported in association with the use of tenofovir disoproxil fumarate, most often in patients with underlying systemic or renal disease, or in patients taking concomitant nephrotoxic agents. Some cases have occurred in patients with no identified risk factors. ATRIPLA should be avoided with concurrent or recent use of a nephrotoxic agent.

ATRIPLA may cause fetal harm when administered during the first trimester to a pregnant woman. Women should not become pregnant or breastfeed while taking ATRIPLA. Barrier contraception must always be used in combination with other methods of contraception such as oral or other hormonal contraceptives. If the patient becomes pregnant while taking ATRIPLA, she should be apprised of the potential harm to the fetus.

Mild to moderate rash is a common side effect of efavirenz. In controlled clinical trials, 26% of patients treated with efavirenz experienced new-onset skin rash compared with 17% of patients treated in control groups. Skin discoloration, associated with emtricitabine, may also occur. ATRIPLA should be discontinued in patients developing severe rash associated with blistering, desquamation, mucosal involvement, or fever. Liver enzymes should be monitored in patients with known or suspected hepatitis B or C and when ATRIPLA is administered with ritonavir or other medications associated with liver toxicity. Decreases in bone mineral density have been seen with tenofovir disoproxil fumarate. Use ATRIPLA with caution in patients with a history of seizures. Convulsions have been observed in patients receiving efavirenz, generally in the presence of known medical history of seizures. Redistribution and/or accumulation of body fat have been observed in patients receiving antiretroviral therapy. Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including the components of ATRIPLA.

Coadministration of ATRIPLA and atazanavir is not recommended due to concerns regarding decreased atazanavir concentrations. Patients on lopinavir/ritonavir plus ATRIPLA should be monitored for tenofovir-associated adverse events. ATRIPLA should be discontinued in patients who develop tenofovir-associated adverse events. Coadministration of ATRIPLA and didanosine should be undertaken with caution. Patients receiving this combination should be monitored closely for didanosine-associated adverse events. See full prescribing information for complete list of drug-drug interactions.

W-5

In a large controlled clinical trial (Study 934), adverse events observed in greater than or equal to 5% of patients in the Viread/Emtriva/SUSTIVA group include dizziness, nausea, diarrhea, fatigue, headache, and rash.

The dose of ATRIPLA is one tablet once daily taken orally on an empty stomach. Dosing at bedtime may improve the tolerability of nervous system symptoms.

Important Information About SUSTIVA

SUSTIVA (efavirenz) in combination with other antiretroviral agents is indicated for the treatment of HIV-1 infection. This indication is based on two clinical trials of at least one year duration that demonstrated prolonged suppression of HIV RNA.

Coadministration with astemizole, cisapride, midazolam, triazolam, ergot derivatives, or voriconazole is contraindicated. Concomitant use of SUSTIVA and St. John’s wort (Hypericum perforatum) or St. John’s wort-containing products is not recommended. This list of medications is not complete.

Serious psychiatric adverse experiences, including severe depression (2.4%), suicidal ideation (0.7%), nonfatal suicide attempts (0.5%), aggressive behavior (0.4%), paranoid reactions (0.4%) and manic reactions (0.2%) have been reported in patients treated with SUSTIVA. In addition to SUSTIVA, factors identified in a clinical study that were associated with an increase in psychiatric symptoms included history of injection drug use, psychiatric history, and use of psychiatric medication. There have been occasional reports of suicide, delusions, and psychosis-like behavior, but it could not be determined if SUSTIVA was the cause. Patients with serious psychiatric adverse experiences should be evaluated immediately to determine whether the risks of continued therapy outweigh the benefits. Fifty-three percent of patients reported central nervous system symptoms including dizziness (28.1%), insomnia (16.3%), impaired concentration (8.3%), somnolence (7.0%), abnormal dreams (6.2%) and hallucinations (1.2%) when taking SUSTIVA compared to 25% of patients receiving control regimens. These symptoms usually begin during Days 1-2 of therapy and generally resolve after the first 2-4 weeks of therapy. After four weeks of therapy, the prevalence of central nervous system symptoms of at least moderate severity ranged from 5% to 9% in patients treated with regimens containing SUSTIVA. Nervous system symptoms are not predictive of the less frequent serious psychiatric symptoms.

SUSTIVA may cause fetal harm when administered during the first trimester to a pregnant woman. Women should not become pregnant or breastfeed while taking SUSTIVA. Barrier contraception must always be used in combination with other methods of contraception (e.g. oral or other hormonal contraceptives). If the patient becomes pregnant while taking SUSTIVA, she should be apprised of the potential harm to the fetus.

Mild to moderate rash is a common side effect of SUSTIVA. In controlled clinical trials, 26% of patients treated with SUSTIVA experienced new-onset skin rash compared with 17% of patients treated in control groups. SUSTIVA should be discontinued in patients developing severe rash associated with blistering, desquamation, mucosal involvement, or fever. Rash is more common and often more severe in pediatric patients.

Liver enzymes should be monitored in patients with known or suspected hepatitis B or C, in patients treated with other medications associated with liver toxicity, and when SUSTIVA is administered with ritonavir. Use SUSTIVA with caution in patients with a history of seizures. Convulsions have been observed in patients receiving efavirenz, generally in the presence of known medical history of seizures. Redistribution and/or accumulation of body fat have been seen in patients receiving antiretroviral therapy. A causal relationship has not been established. Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including SUSTIVA.

It is recommended that SUSTIVA be taken on an empty stomach, preferably at bedtime. The increased concentrations following administration of SUSTIVA with food may lead to an increase in frequency of adverse events. Dosing at bedtime may improve the tolerability of nervous system symptoms.

Additional Important Information About Truvada

Truvada is a fixed-dose combination product that combines 200 mg of Emtriva^® (emtricitabine) and 300 mg of Viread^® (tenofovir disoproxil fumarate) in one tablet, taken once a day. In the United States, Truvada is indicated in combination with other antiretroviral agents (such as non-nucleoside reverse transcriptase inhibitors or protease inhibitors) for the treatment of HIV-1 infection in adults. Truvada should not be coadministered with Emtriva, Viread or lamivudine-containing products and it is not recommended that Truvada be used as a component of a triple nucleoside regimen. In treatment-experienced patients, the use of Truvada should be guided by laboratory testing and treatment history.

Clinical Study 934 supports the use of Truvada tablets for the treatment of HIV-1 infection. Additional data in support of the use of Truvada are derived from Study 903, in which Viread and lamivudine were used in combination in treatment-naïve adults, and clinical Study 303, in which Emtriva and lamivudine demonstrated comparable efficacy, safety and resistance patterns as part of multidrug regimens.

No drug interaction studies have been conducted using Truvada. Drug interactions have been observed when didanosine, atazanavir, or lopinavir/ritonavir are co-administered with Viread, a component of Truvada, and dose adjustments may be necessary. Data are not available to recommend a dose adjustment of didanosine for patients weighing less than 60 kg. Patients on atazanavir or lopinavir/ritonavir plus Truvada should be monitored for Truvada-associated adverse events that may require discontinuation. When co-administered with Truvada, it is recommended that atazanavir 300 mg be given with ritonavir 100 mg. Atazanavir without ritonavir should not be co-administered with Truvada.

Four-hundred and forty-seven HIV-1 infected patients have received combination therapy with Emtriva and Viread with either a non-nucleoside reverse transcriptase inhibitor (Study 934) or protease inhibitor for 48 weeks in clinical studies. Adverse events observed in Study 934 were generally consistent with those seen in other studies in treatment-experienced or treatment-naïve patients receiving Viread and/or Emtriva. Adverse events observed in more than 5% of patients in the Viread/Emtriva group in Study 934 include diarrhea, nausea, fatigue, headache, dizziness and rash.

Renal impairment, including cases of acute renal failure and Fanconi syndrome (renal tubular injury with severe hypophosphatemia), has been reported among patients taking Viread, a component of Truvada (emtricitabine and tenofovir disoproxil fumarate). Renal impairment

W-7

occurred most often in patients with underlying systemic or renal disease or in patients taking concomitant nephrotoxic agents, though some cases have appeared in patients without identified risk factors. Decreases in bone mineral density (BMD) at the lumbar spine and hip have been seen with the use of Viread. Redistribution and/or accumulation of body fat have been observed in patients receiving antiretroviral therapy. Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy including Truvada, Viread and Emtriva.

The effects of Viread-associated changes in BMD and biochemical markers on long-term bone health and future fracture risk are unknown. Skin discoloration, manifested by hyperpigmentation on the palms and/or soles, has been reported with the use of Emtriva, a component of Truvada. Skin discoloration was generally mild and asymptomatic and its mechanism and clinical significance are unknown.

The parent compound of Viread was discovered through a collaborative research effort between Dr. Xxxxxxx Holy, Institute for Organic Chemistry and Biochemistry, Academy of Sciences of the Czech Republic (IOCB) in Prague and Xx. Xxxx XxXxxxxx, Rega Institute for Medical Research, Katholic University in Leuven, Belgium.
