(a) Notwithstanding the foregoing in this Section 1.25, amounts received by COMPANY, its Affiliates or sublicensees for the sale of Licensed Products among COMPANY, its Affiliates and sublicensees for resale shall not be included in the computation of Net Selling Price hereunder.

(b) For purposes of this Section 1.25, “Distributor” shall mean any third party (i) to which a Seller has granted (at any time during the term) a right to sell or distribute a Licensed Product, (ii) that sells Licensed Products to hospitals and/or pharmacies for their sale to or use with patients (rather than to other third parties for resale to hospitals and/or pharmacies for their sale to or use with patients), and (iii) that does not make payments to COMPANY or such COMPANY Affiliate that are calculated on the basis of a percentage of, or profit share on, such third party’s sales of Licensed Products.

(c) Where Licensed Product is sold in the form of a combination product containing one or more active ingredients in addition to a Licensed Compound (“Combination Product”), Net Selling Price for such Combination Product for purposes of determining royalties payable under this Agreement will be calculated by multiplying the actual Net Selling Price of such Combination Product by the fraction A/(A+B) where A is the Net Selling Price for the stock keeping unit most comparable in formulation and dosing to that used for the Combination Product of the Licensed Product containing the relevant Licensed Compound as the sole active ingredient, if sold separately, in such country during the relevant fiscal quarter, and B is the Net Selling Price for the stock keeping unit, most comparable in formulation and dosing to that used for the Combination Product, of any other active ingredient, if sold separately, in such country during the relevant fiscal quarter. For clarity, if there are three or more active ingredients (including the Licensed Compound), additional B terms calculated in the same manner, shall be included in the denominator so that such fraction shall be A/(A+B_l+B₂+...). If, on a country-by-country basis, one or more of the other active ingredients in the Combination Product are not sold separately in said country, Net Selling Price for the purpose of determining royalties payable under this Agreement for the Combination Product shall be calculated by multiplying the actual Net Selling Price of such Combination Product by the fraction A/C where A is the Net Selling Price for the stock keeping unit most comparable in formulation and dosing to that used for the Combination Product of the Licensed Product containing the relevant Licensed Compound as the sole active ingredient, if sold separately, in such country during the relevant fiscal quarter and C is the Net Selling Price for the Combination Product in such country during the relevant fiscal quarter. If, on a country-by-country basis, the Licensed Product containing a Licensed Compound as the sole active ingredient is not sold separately in

- 22 -

said country during the relevant fiscal quarter but one or more of the other active ingredients in the Combination Product are sold separately in said country during the relevant fiscal quarter, the Net Selling Price for the Combination Product shall be calculated by multiplying the actual Net Selling Price of such Combination Product by the fraction (1-(D/C)) where D is the Net Selling Price for the stock keeping unit most comparable in formulation and dosing to that used for the Combination Product of the product containing the other active ingredient as the sole active ingredient and C is the Net Selling Price for the Combination Product in such country during the relevant fiscal quarter. If, on a country-by-country basis, the Licensed Product containing a Licensed Compound as the sole active ingredient is not sold separately and one or more of the other active ingredients in the Combination Product are not sold separately in such country during the relevant fiscal quarter Net Selling Price for the purposes of determining royalties of the Combination Product shall be deemed to be the Net Selling Price of such Combination Product multiplied by a fraction, the numerator of which is the number of Licensed Compounds in such Combination Product and the denominator of which is the number of all active ingredients in such Combination Product.

1.26 “Other Change” shall mean (i) an amendment, supplement or modification (other than a written amendment) to an agreement that might reasonably be expected to have an adverse effect on LICENSOR’s or ROYALTY PHARMA’s rights or obligations under this Agreement, or (ii) a waiver of a term of an agreement that might reasonably be expected to have an adverse effect on LICENSOR’s or ROYALTY PHARMA’s rights or obligations under this Agreement.

1.27 “Registration” shall mean, in relation to any Licensed Product, such approvals by the regulatory authorities in a given country (including pricing approvals) as may be legally required before such Licensed Product may be commercialized or Sold in such country.

1.28 “Royalty Pharma Indemnitees” shall mean ROYALTY PHARMA and all its Affiliates and their respective trustees, directors, employees, investors, partners (limited or otherwise), members and other equity and interest holders.

1.29 “Sale” or “Sold” shall mean the sale, transfer, exchange or other disposition of Licensed Products whether by gift or otherwise, subsequent to Registration in a given country (if such Registration is required) by a Seller to make such sale, transfer, exchange or disposition, to any party that is not a Seller. Sales of Licensed Products shall be deemed consummated upon the first to occur of: (a) receipt of payment from the purchase; (b) delivery of Licensed Products to the purchaser or a common carrier; (c) release of Licensed Products from consignment; or (d) if otherwise transferred, exchanged or disposed of, whether by gift or otherwise, when such transfer, exchange, gift or other disposition occurs. Notwithstanding the foregoing definition of Sale, to the extent COMPANY distributes any Licensed Product under a Treatment IND or through an expanded access program or the Global Access Program, only to the extent that the actual Net Selling Price exceeds Fully Absorbed Costs therefor will such distribution be considered a Sale. If the actual Net Selling Price exceeds the Fully

- 23 -

Absorbed Costs, the distribution shall be deemed to be a Sale with a deemed Net Selling Price (prior to any application of Section 1.25(c)) for purposes of Section 3.2 of the difference between the actual Net Selling Price and the Fully Absorbed Cost therefor.

1.30 “Settlement Agreement” shall mean the Settlement Agreement, dated as of May 6, 1999, by and among Glaxo Wellcome plc and GW on the one hand, and LICENSOR, COMPANY and ▇▇. ▇▇▇▇▇ ▇. ▇▇▇▇▇ on the other hand, providing for the settlement, release and dismissal of the FTC litigation and related claims (including but not limited to Civil Action 1:96-CV-1754-GET), and certain claims of ▇▇. ▇▇▇▇▇ ▇. ▇▇▇▇▇ against Glaxo Wellcome, plc, GW and their Affiliates.

1.31 “U.S. Government Licenses” shall mean the non-exclusive licenses to the U.S. Government or agencies thereof pursuant to [ * ], copies of which licenses are attached hereto as Appendix “B.”

1.32 “Valid Claim” shall mean (a) an issued claim of any unexpired patent included among the Licensed Patents, or (b) a pending claim of any pending patent application included among the Licensed Patents, which has not been held unenforceable, unpatentable or invalid by a decision of a court or governmental body of competent jurisdiction, unappealable or unappealed within the time allowed for appeal, which has not been rendered unenforceable through disclaimer or otherwise or which has not been lost through an interference proceeding.

3.2 Payments from COMPANY

(a) {Intentionally deleted}

(b) COMPANY shall pay ROYALTY PHARMA, a royalty equal to the following percentages of the Net Selling Price of Licensed Products Sold on or after July 1, 2005, in the Licensed Territory by COMPANY and its Affiliates and sublicensees for HIV and HBV indications:

(i)


Percentage of Net Selling Price		Annual Net Selling Price of Licensed Products for HIV
[ * ]		[ * ]

(ii)


Percentage of Net Selling Price		Annual Net Selling Price of Licensed Products for HBV
[ * ]		[ * ]

Royalties (at the rates set forth in Subsections 3.2(b), subject to reduction or modification only as prescribed herein) shall be paid in respect of a given Licensed Product for a period of [ * ] after commercial introduction of such Licensed Product in a given country. Thereafter, royalties shall be paid only so long as the manufacture, use, offer for sale, sale or importation of such Licensed Product in such country would, in the absence of a license, infringe a Valid Claim of an issued and unexpired patent within the Licensed Patents. If, during such [ * ] period, a third party or third parties commence selling a therapeutic product in a country in which there are no Valid Claims or are Valid Claims only of the type described in Section 1.32(b) and (i) such product contains any Licensed Compound (“unlicensed unit

- 29 -

sales”) and (ii) such unlicensed unit sales for any royalty period amount to [ * ] or more of the COMPANY’S unit sales of such Licensed Product in such country in such royalty period, determined in accordance with Subsection 3.2(d) below, then COMPANY’s royalty obligation in such country with respect to such Licensed Product shall be suspended commencing with the royalty period next succeeding the royalty period in which such [ * ] threshold was initially exceeded and shall resume with the royalty period next succeeding the first royalty period in which such [ * ] threshold is no longer exceeded. COMPANY’s royalty obligations with respect to such Licensed Product shall resume in such country if and when such Valid Claim per Subsection 1.32(b) becomes a Valid Claim per Subsection 1.32(a).

(d) Unit Sales. For purposes of this Section 3.2, (i) “unlicensed unit sales” and “COMPANY unit sales” shall be deemed to mean the grams of Licensed Compound in third party product (irrespective of dosage form) or the Licensed Product (irrespective of dosage form), respectively, as reflected on the label of each such unit; and (ii) unlicensed unit sales shall be determined by the sales reports of IMS America Ltd. of Plymouth Meeting, Pennsylvania (“IMS”) or any successor to IMS or any other independent marketing auditing firm selected by COMPANY or its sublicensees and reasonably acceptable to ROYALTY PHARMA. If COMPANY is entitled to a royalty suspension based on unlicensed unit sales pursuant to Subsection 3.2(c) for any royalty period, it or its sublicensees shall submit the sales report of IMS or such other independent firm, as applicable, for the relevant royalty period to ROYALTY PHARMA, together with COMPANY’s or its sublicensees’ sales report for the relevant royalty period. Such sales reports for each royalty period in which COMPANY is entitled to such royalty suspension shall be submitted with the royalty report for such royalty period submitted pursuant to Section 4.1.

3.3 Annual Minimum Royalties

(a) Subject to Subsection 3.3(c), in the event that COMPANY’s total annual royalty payment to ROYALTY PHARMA pursuant to Subsection 3.2(b)(i) above during the calendar year [ * ] and each calendar year thereafter for so long as there exist Valid Claims in the U.S. is less than the annual minimum royalty set forth opposite such year below (the “Annual Minimum”), COMPANY shall make a payment to ROYALTY PHARMA together with the report for the fourth quarter of such year required in Section 4.1 of this Agreement equal to the difference between such Annual Minimum and the total royalties paid to ROYALTY PHARMA for the preceding year pursuant to Subsection 3.2(b)(i) above:


Calendar Year		Annual Minimum
[ * ]		[ * ]

(b) Subject to Subsection 3.3(c), in the event that COMPANY’s total annual royalty payment to ROYALTY PHARMA pursuant to Subsection 3.2(b)(ii) above during the [ * ] calendar year following the year during which the first Registration in a Major Market Country is granted for a Licensed Product covered by Subsection 3.2(b)(ii)

- 30 -

above and each calendar year thereafter for so long as there exist Valid Claims in the U.S. is less than the annual minimum royalty set forth opposite such year below (the “Annual Minimum”), COMPANY shall make a payment to ROYALTY PHARMA together with the report for the fourth quarter of such year required in Section 4.1 of this Agreement equal to the difference between such Annual Minimum and the total royalties paid to ROYALTY PHARMA for the preceding year pursuant to Subsection 3.2(b)(ii) above:


Calendar Year		Annual Minimum
[ * ]		[ * ]

(c) If during a given year, the sum of royalty payments paid hereunder for all Licensed Products described in Subsection 3.2(b) of this Agreement exceeds the sum of the applicable Annual Minimums which are required to be paid for such year pursuant to Subsections 3.3(a) and 3.3(b), COMPANY shall be deemed to have satisfied the requirements of each of Subsections 3.3(a) and 3.3(b) for such year. For any year in which no Valid Claims exist in the United States for the entire year or this Agreement is not in effect for the entire year, the Annual Minimum shall be prorated accordingly.

(d) [ * ], COMPANY may credit solely against running royalties (paid pursuant to Section 3.2), all reasonable costs incurred by COMPANY after the date hereof in connection with any litigation, interference, opposition or other inter partes action pertaining to the validity, enforceability, allowability or subsistence of the Licensed Patents or whether COMPANY’s practice of the Licensed Patents infringes a third-party patent. Until [ * ], the amount of such credits shall not exceed in any year [ * ] of the royalty payments due hereunder in such year.

Such costs shall not be credited against any other payments due to ROYALTY PHARMA under this Agreement.

3.4 Accrual of Royalties

No royalty shall be payable on a Licensed Product made, sold, or used for tests or development purposes or distributed as samples. No royalties shall be payable on sales among COMPANY, its Affiliates and sublicensees, but royalties shall be payable on subsequent sales by COMPANY, its Affiliates or sublicensees to a third party. No multiple royalty shall be payable because the manufacture, use or sale of a Licensed Product is covered by more than one Valid Claim or at least one Valid Claim and the Licensed Technology.

3.5 Third Party Royalties

(a) If COMPANY, its Affiliates or sublicensees determine after consultation with ROYALTY PHARMA, but at COMPANY’s discretion, that it or they are required to pay royalties or other fees to any third party (including under any third

- 31 -

party or GW license to which Section 2.6 applies) because the manufacture, use, offer for sale, importation, or sale of a Licensed Product infringes any patent or other intellectual property rights of such third party in a given country (“Third Party Royalties”), COMPANY, its Affiliates or sublicensees may deduct from running royalties thereafter due to ROYALTY PHARMA (per Section 3.2(c) of this Agreement) with respect to the Net Selling Price of such Licensed Product in such country up to [ * ] of the Third Party Royalties. In no event shall the royalties due on such Sales of such Licensed Product in such country on account of any reduction pursuant to this Subsection 3.5(a) be thereby reduced to less than [ * ] on such Sales of such Licensed Product in such country.

(b) If the sum of (i) the royalties paid hereunder (taking into account all royalty deductions and credits taken with respect to such royalties, including those in Section 3.5(a)), plus (ii) [ * ] of all Third Party Royalties paid in respect of the manufacture, use, offer for sale, importation or sale of a Licensed Compound as contained in a given Licensed Product in a given country exceeds, at any time, [ * ] of the Net Selling Price for such Licensed Product, upon COMPANY’s request, ROYALTY PHARMA and COMPANY agree to negotiate in good faith in an effort to agree on a reduction in the royalties payable hereunder to ROYALTY PHARMA for such Licensed Product in such country.

(c) COMPANY shall be responsible for paying the royalties due to GW under the GW License Agreement resulting from sale of Licensed Products (as defined in the GW License Agreement) by COMPANY, its Affiliates and sublicensees. COMPANY hereby indemnifies (i) [ * ], and (ii) [ * ]. COMPANY will pay such royalties directly to GW, as prescribed by the GW License Agreement, with notice to LICENSOR and ROYALTY PHARMA. COMPANY’s obligation under this paragraph (c) shall terminate in respect of a given country upon the expiration or termination of the GW License Agreement in such country.

(d) The royalties actually paid by COMPANY, its Affiliates and sublicensees under the GW License Agreement shall be deemed to be “Third Party Royalties” under Section 3.5(a) and COMPANY, its Affiliates and sublicensees shall have the right of deduction pursuant to this Section 3.5 with respect to the royalties paid thereunder to GW. [ * ].

3.6 Compulsory Licenses

Should a compulsory license be granted to any third party in any country of the Licensed Territory to make, have made, use, import, offer for sale or sell Licensed Products, the royalty rate payable thereunder for sales of the Licensed Products by COMPANY in such country [ * ].

3.7 Reduction in Royalty Due to Invalid Claims

In the event that all applicable claims of all patents or patent applications included within the Licensed Patents under which COMPANY is selling or actively developing a Licensed Product shall be held invalid or not infringed by the Licensed Products COMPANY is selling or actively developing by a court of competent jurisdiction in a given country of the Licensed Territory, whether or not there is a conflicting decision by another court of competent jurisdiction in such country, COMPANY may cease all royalty payments on its, its Affiliates’ or its sublicensees’ sales of such Licensed Product covered by such claims and, if it does so, shall deposit such royalty payments in an interest-bearing escrow account until such judgment is finally reversed by an unappealed or unappealable decree of a court of competent jurisdiction of higher dignity in such country or is otherwise unappealable or is unappealed within the time allowed therefor; provided, however, that if such judgment is finally reversed by an unappealed or unappealable decree of a court of competent jurisdiction of higher dignity in such country, the former royalty payments shall be resumed and the royalty payments not theretofore made and interest earned thereon shall become due and payable to ROYALTY PHARMA.

ROYALTY PHARMA agrees that, to the extent LICENSOR does not make such payment within sixty (60) days, COMPANY, its Affiliates and sublicensees may credit up to [ * ] of such amounts so not paid against any royalties payable hereunder to ROYALTY PHARMA. The exercise by COMPANY of the right set forth in the immediately preceding sentence shall not affect LICENSOR’s obligations to ROYALTY PHARMA set forth in Sections 3.8(b)(i) and (ii).

(d) COMPANY agrees that, to the extent it, or any of its Affiliates or sublicensees credit any amounts owed by LICENSOR against royalties payable hereunder to ROYALTY PHARMA pursuant to this Section 3.8, and COMPANY, or any of its Affiliates or sublicensees thereafter recovers such amounts so credited from LICENSOR, COMPANY will immediately pay such amounts so credited to ROYALTY PHARMA.

Notwithstanding anything to the contrary contained herein but subject to Section 9.4, ROYALTY PHARMA may disclose written information and data supplied by LICENSOR or COMPANY to any rating agency, any note holder of ROYALTY PHARMA or its Affiliates, or any insurer thereof, provided in each case that such agency, holder or insurer is subject to commercially reasonable confidentiality obligations.

- 46 -

9.3 Release from Restrictions

The obligation not to disclose Information shall not apply to any part of such Information that:

(a) is or becomes patented, published or otherwise part of the public domain, other than by unauthorized acts of the party obligated not to disclose such Information (for purposes of this Article 9 the “receiving party”) or its Affiliates or sublicensees in contravention of this Agreement; or

(b) is disclosed to the receiving party or its Affiliates or sublicensees by a third party provided that such Information was not obtained by such third party directly or indirectly from the other party to this Agreement; or

(c) prior to disclosure under this Agreement, was already in the possession of the receiving party, its Affiliates or sublicensees, provided that such Information was not obtained directly or indirectly from the other party to this Agreement; or

(d) results from research and development by the receiving party or its Affiliates or sublicensees, independent of disclosures from the other party of this Agreement, provided that the persons developing such information have not had exposure to the information received from the other party to this Agreement; or

(e) is required by law to be disclosed by the receiving party, provided that the receiving party uses reasonable efforts to notify the^-other party immediately upon learning of such requirement in order to give the other party reasonable opportunity to oppose such requirement; or

(f) in the case of Information disclosed by a party to this Agreement, if such party agrees in writing that such Information may be disclosed by the party to this Agreement to whom such Information has been disclosed by such party.

9.4 GSK/Shire and GW Confidentiality

If COMPANY or LICENSOR provides to ROYALTY PHARMA or any sublicensee or any other third party any information or data which was furnished to LICENSOR under the GSK/Shire Agreement or the GW Agreements and then provided to COMPANY, or if COMPANY discloses to any sublicensee or to any other third party any specific terms of the GSK/Shire Agreement or the GW Agreements, COMPANY shall ensure that such sublicensee or third party is subject to the confidentiality obligations imposed on sublicensees under, as applicable, (i) Article 9 and Section 13.3 of the GSK/Shire Agreement; (ii) Article 3 of the Settlement Agreement; and (iii) Article

- 47 -

12 and Section 15.3 of the GW License Agreement. ROYALTY PHARMA agrees that it is subject to the confidentiality obligations referred to in clauses (i), (ii) and (iii) of the immediately preceding sentence.

ARTICLE 10.

TERM AND ENFORCEMENT

10.1 Term

The term of this Agreement shall commence on the date of this Agreement and shall continue in full force and effect until the expiration of (a) the last to expire Valid Claim or (b) COMPANY’s obligations to pay royalties hereunder, whichever is last to occur. Upon the expiration of this Agreement pursuant to this Section 10.1, the licenses granted under Section 2.1 shall remain fully paid-up, perpetual and irrevocable (notwithstanding Sections 10.4(a) and 10.5).

10.2 Failure to Enforce

The failure of any party, at any time, or for any period of time, to enforce any of the provisions of this Agreement, shall not be construed as a waiver of such provisions or as a waiver of the right of such party thereafter to enforce each and every such provision of this Agreement.

10.3 No Termination

No party to this Agreement shall have the right to terminate, nor shall any party to this Agreement seek to terminate or encourage any others to terminate or seek to terminate, this Agreement for any reason, but instead upon any breach of any obligation owed under this Agreement, a party may seek money damages or equitable relief through Section 14.1, if applicable, or through other means.

10.4 Bankruptcy

The parties intend for this Agreement to be treated as an “executory” contract under Title 11 of the U.S. Code and other applicable bankruptcy law (“Title 11”). In the event that COMPANY becomes a debtor under Title 11:

(a) If this Agreement is rejected as provided in or pursuant to Title 11, (i) such rejection shall not serve to terminate this Agreement as between ROYALTY PHARMA and LICENSOR (and if this Agreement is terminated or otherwise rendered unenforceable as a result of such rejection or otherwise in connection with COMPANY’s Title 11 proceeding, LICENSOR and ROYALTY PHARMA shall be deemed to have entered into a like agreement in replacement thereof, which they shall confirm by written agreement), (ii) neither LICENSOR nor ROYALTY PHARMA shall be treated as having assumed or otherwise be liable to the other for any obligations of COMPANY under this Agreement (including any obligations to LICENSOR or ROYALTY PHARMA), (iii)

- 48 -

following such rejection, ROYALTY PHARMA and LICENSOR shall use commercially reasonable efforts jointly to seek to obtain a new licensee to market the Licensed Products in accordance with the terms of this Agreement, to enjoy the rights of COMPANY under this Agreement and to assume the obligations of COMPANY under this Agreement (including all obligations to LICENSOR and ROYALTY PHARMA) (the “Re-license”) and (iv) LICENSOR shall use commercially reasonable efforts (without any requirement to make payments as a result thereof) to preserve its rights under the GSK/Shire Agreement and the GW Agreements so as to make them available for the Re-license. LICENSOR and ROYALTY PHARMA agree to negotiate the terms and conditions of the Re-license in good faith and such that Re-license will provide that (A) LICENSOR shall be reimbursed for its out-of-pocket expenses incurred as a result of COMPANY becoming a debtor under Title 11 and the Re-license, (B) the new licensee under the Re-license will bear all obligations of COMPANY to LICENSOR and ROYALTY PHARMA under this Agreement including Sections 3.5(c), 8.5 and 8.6 hereof and (C) the new licensee will make payment of royalties and other amounts, other than amounts owed to LICENSOR under this Agreement, to ROYALTY PHARMA with LICENSOR not being entitled to any such payments. Neither LICENSOR nor ROYALTY PHARMA will have any obligation to enter into the Re-license unless such Re-license complies with the immediately preceding sentence. Nothing in this paragraph shall be construed to require LICENSOR to make any payment to ROYALTY PHARMA in connection with such rejection or Re-license or to require ROYALTY PHARMA to make any payment to LICENSOR in connection with such rejection or Re-license.

(b) If COMPANY (in any capacity, including as a debtor-in-possession or by a Title 11 trustee) seeks, pursuant to or as provided in Title 11, to assume this Agreement, and if LICENSOR’s consent or other approval is required for such assumption, LICENSOR shall exercise any such consent or other approval rights at ROYALTY PHARMA’s written direction, and further shall not object to or otherwise challenge any such assumption without ROYALTY PHARMA’s prior written consent, as long as, in each case, doing so shall not expose LICENSOR to any liability other than as provided in this Agreement. If COMPANY (in any capacity, including as a debtor-in-possession or by a Title 11 trustee) seeks, pursuant to or as provided in Title 11, to assume and assign this Agreement, and if LICENSOR’s consent or other approval is required for such assumption and assignment, LICENSOR shall not unreasonably withhold or delay such consent.

The foregoing provisions of this Section 10.4 are without prejudice to any other rights or remedies LICENSOR or ROYALTY PHARMA may have arising under this Agreement, Title 11 or other applicable law.

10.5 Diligence

If during the term of this Agreement COMPANY and its sublicensees cease to market, promote and sell (other than for safety or other regulatory reasons) all of the Licensed Products previously Registered in all of the Major Market Countries for a period of [ * ], then within [ * ] of ROYALTY PHARMA’s written request, COMPANY

- 49 -

shall meet with ROYALTY PHARMA to discuss COMPANY’s future commercialization plans for such Licensed Products. Notwithstanding the foregoing, the [ * ] period described in the preceding sentence shall be extended for so long as COMPANY experiences a suspension of manufacturing of Licensed Product for reasons not within its control and COMPANY is using reasonable commercial efforts to have such manufacturing resumed. If within [ * ] of COMPANY’s receipt of such written request, COMPANY shall have failed to provide reasonable evidence to ROYALTY PHARMA of COMPANY’s marketing and sale of any one or more Licensed Products in any one or more of the Major Market Countries, then effective upon written notice from ROYALTY PHARMA:

(a) all of the rights and obligations of COMPANY hereunder (including all obligations to LICENSOR) shall be immediately and irrevocably transferred to a new licensee designated by ROYALTY PHARMA (“New Licensee”), whose identity is subject to the prior written consent of LICENSOR, which consent shall not be unreasonably withheld or delayed, with New Licensee becoming “COMPANY” hereunder for such purposes, provided that COMPANY shall not be required to transfer any rights to intellectual property other than the Licensed Patents except as provided below in this Section 10.5;

(b) COMPANY shall no longer be a party to this Agreement and shall have no rights or obligations hereunder, other than as provided pursuant to this Section 10.5 and those accrued prior to delivery of such written notice;

(c) LICENSOR shall not make or otherwise advance any claim or other position that diminishes or otherwise impairs the rights afforded ROYALTY PHARMA by the preceding Sections 10.5(a) and 10.5(b); and

(d) following the transfer in subsection (a), New Licensee’s right to assign the rights of COMPANY hereunder shall be subject to the prior written consent of LICENSOR, which consent shall not be unreasonably withheld or delayed.

In the event of any transfer of the license and rights pursuant to this Section 10.5, ROYALTY PHARMA and COMPANY shall negotiate in good faith and agree upon commercially reasonable terms for (i) the transfer of technology, intellectual property rights, including patents and trademarks, manufacturing contracts and rights, regulatory filings and approvals (including NDAs and drug master files), and such other matters as ROYALTY PHARMA and COMPANY agree are necessary and appropriate to transfer to New Licensee to enable New Licensee and its Affiliates and sublicensees to manufacture, have manufactured, use, sell, offer for sale, market, import and promote Licensed Compounds; (ii) [ * ]; and other relevant factors); (iii) [ * ] to the extent that ROYALTY PHARMA and COMPANY agree that COMPANY shall [ * ]; and (iv) [ * ] (to the extent those matters are not already addressed by the preceding clause (ii)). Notwithstanding the foregoing, [ * ] pursuant to this Section 10.5).

- 50 -

ROYALTY PHARMA shall promptly reimburse LICENSOR for all reasonable expenses LICENSOR incurs in connection with any assignments described in Sections 10.5(a) and (d). The foregoing provisions of this Section 10.5 are without prejudice to any other rights or remedies ROYALTY PHARMA or LICENSOR may have arising under this Agreement or other applicable law.

ARTICLE 11.

14.11 Severability

All rights and restrictions contained herein may be exercised and shall be applicable and binding only to the extent that they do not violate any applicable laws and are intended to be limited to the extent necessary so that they will not render this Agreement illegal, invalid or unenforceable. If any provision or portion of any provision of this Agreement, not essential to the commercial purpose of this Agreement, shall be held to be illegal, invalid or unenforceable by a court of competent jurisdiction, it is the intention of the parties that the remaining provisions or portions thereof shall constitute their agreement with respect to the subject matter hereof, and all such remaining provisions, or portions thereof, shall remain in full force and effect.

FOR IMMEDIATE RELEASE

GILEAD SCIENCES AND ROYALTY PHARMA ANNOUNCE $525 MILLION AGREEMENT WITH EMORY UNIVERSITY TO PURCHASE ROYALTY INTEREST FOR EMTRICITABINE

Foster City, CA, New York, NY and Atlanta, GA, July 18, 2005 – Gilead Sciences, Inc. (Nasdaq: GILD) and Royalty Pharma today announced that the companies have entered into an agreement with Emory University providing for the purchase of the royalty interest owed to Emory for emtricitabine, also known as Emtriva^® . Under the terms of the agreement, Gilead and Royalty Pharma will make a one-time cash payment of $525 million to Emory in exchange for elimination of the emtricitabine royalties due to Emory on worldwide net sales of the product. The transaction, which is subject to customary closing conditions, is expected to close on or before July 29, 2005.

Gilead and Royalty Pharma will pay 65 and 35 percent, respectively, of the $525 million cash payment to Emory. Following this transaction, Gilead will be obligated to pay to Royalty Pharma royalty revenue based on all future emtricitabine net sales relative to Royalty Pharma’s contribution to the Emory royalty buyout. Gilead will continue to have obligations to pay certain royalties to GlaxoSmithKline, fulfilling Emory’s obligations under a previous agreement. Within 30 days of closing, Emory and certain inventors of emtricitabine may acquire interests in Royalty Pharma approximating up to 25 percent of the proceeds payable by Royalty Pharma in the transaction.

Lazard is acting as financial advisor to Gilead and Citigroup is acting as financial advisor to Emory and the inventors.

The University’s share of the transaction will be reinvested in Emory’s research mission following the terms of the ▇▇▇▇-▇▇▇▇ Act passed by Congress in 1980 to encourage commercialization of research by universities.

“We feel privileged and humbled to receive such extraordinary recognition for the value of our intellectual property,” said Emory University President Dr. ▇▇▇▇▇ ▇▇▇▇▇▇. “These dividends will be plowed back into our mission of research and discovery for the benefit of our state, our nation and the world, in accordance with the priorities we have identified in our University-wide strategic plan.”

Emtricitabine was discovered by Emory researchers ▇▇. ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, ▇▇. ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇ and ▇▇. ▇▇▇-▇▇▇▇ ▇▇▇▇ and licensed to Triangle Pharmaceuticals by Emory University in 1996. Triangle was acquired by Gilead in 2003. Emtricitabine, marketed by Gilead as Emtriva, was first approved by the U.S.

Food and Drug Administration in July 2003 for the treatment of HIV infection in combination with other antiretroviral agents. Emtricitabine is a component of Truvada^® (emtricitabine and tenofovir disoproxil fumarate), approved by the U.S. Food and Drug Administration in August 2004 for the treatment of HIV infection in combination with other antiretroviral agents. Emtricitabine is also a component of the triple fixed-dose combination product under development by the ▇▇▇▇▇▇▇-▇▇▇▇▇ Squibb and Gilead Sciences joint venture. In connection with amending and restating the license agreement, Gilead will make a one-time payment of $15 million to Emory on closing of the transaction.

Under the terms of Emory University’s intellectual property policy in effect at the time of the discovery, the majority share of the proceeds will go to the University, including various proportions to the central administration and schools, academic departments, and laboratories of the faculty inventors, who were based in the School of Medicine’s Department of Pediatrics and in Emory College’s Department of Chemistry. A minority share of the proceeds will go to ▇▇. ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇ Professor of Chemistry; ▇▇. ▇▇▇▇▇▇▇▇, professor of pediatrics and senior research career scientist at the Atlanta Veterans Affairs Medical Center; and ▇▇. ▇▇▇▇, a former Emory researcher who is now CEO of FOB Synthesis, Inc., a new drug development company in Atlanta. They have developed a number of other significant anti-HIV and anti-hepatitis B compounds.

Drs. ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇▇ were recognized in 2003 with the top honor from the Georgia Biomedical Partnership, the Biomedical Industry Growth Award, for making a series of significant contributions to research that resulted in successful drug development. Their work in AIDS began in the mid-1980s when they established the first HIV laboratory at Emory.

Tenofovir, the active agent in Viread^® (tenofovir disoproxil fumarate) and second component in Truvada, was discovered through a collaborative research effort between Dr. ▇▇▇▇▇▇▇ Holy, Institute for Organic Chemistry and Biochemistry, Academy of Sciences of the Czech Republic (IOCB) in Prague and ▇▇. ▇▇▇▇ ▇▇▇▇▇▇▇▇, Rega Institute for Medical Research, Katholic University in Leuven, Belgium. Emory University and the inventors of both Viread and Emtriva have agreed to waive their right to a royalty on sales of Truvada in the Gilead Access Program countries to ensure the product can be offered at a no-profit price in parts of the world where the epidemic has hit the hardest.

About Truvada

Truvada combines Emtriva and Viread 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.

Emtriva and Viread have each been studied as part of multi-drug regimens and have been found to be safe and effective. In clinical study 303 Emtriva and lamivudine (3TC) demonstrated comparable efficacy, safety and resistance patterns as part of multidrug regimens. These data, and those from study 903, in which lamivudine and tenofovir were used in combination, support the use of Truvada for the treatment of HIV-1 infection in treatment-naive adults. 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.

Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including Viread. 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.

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-naive 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 five 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 one 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.

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-naive 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 coadministered 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 and increases in biochemical markers of bone metabolism 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 five 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 one percent of patients discontinued participation because of gastrointestinal events.
