The Company will deliver, without charge, (i) to the Representatives, two signed copies of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith; and (ii) to each Underwriter (A) a conformed copy of the Registration Statement as originally filed and each amendment thereto (without any exhibits) and (B) during the Prospectus Delivery Period (as defined below), as many copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) and each Issuer Free Writing Prospectus as the Representatives may reasonably request. As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Securities as in the opinion of counsel for the Underwriters a prospectus relating to the Securities is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Securities by any Underwriter or dealer.

The Company will advise the Representatives promptly, and confirm such advice in writing, (i) when the Registration Statement has become effective; (ii) when any amendment to the Registration Statement has been filed or becomes effective; (iii) when any supplement to the Prospectus or any amendment to the Prospectus or any Issuer Free Writing Prospectus has been filed; (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (v) of the issuance by the

Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (vi) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Information or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vii) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (viii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will use its reasonable best efforts to obtain as soon as possible the withdrawal thereof.

(e) Time of Sale Information. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(f) Ongoing Compliance. If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law.

(g) Blue Sky Compliance. The Company will qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Securities; provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

(h) Earning Statement. The Company will make generally available to its security holders and the Representatives as soon as practicable an earning statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the “effective date” (as defined in Rule 158) of the Registration Statement.

(i) Clear Market. During the period from the date hereof through and including the business day following the Closing Date, the Company will not, without the prior written consent of the Representatives, directly or indirectly, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Company and having a tenor of more than one year.

(j) Use of Proceeds. The Company will apply the net proceeds from the sale of the Securities as described in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Use of Proceeds”.

(k) No Stabilization. The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(l) Record Retention. The Company will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

5. Certain Agreements of the Underwriters. Each Underwriter hereby represents and agrees that it has not used, authorized use of, referred to, or participated in the planning of use of, and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Annex B or prepared pursuant to Section 3(c) or Section 4(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing.

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information contained in the seventh paragraph of the Preliminary Prospectus and the Prospectus under the heading “Underwriting.”

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request, and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and

indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover the prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company, on the one hand, and the Underwriters, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or the NASDAQ Global Select Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

RE: Gilead Sciences, Inc. – Offering of Senior Notes

Ladies and Gentlemen:

We have acted as special counsel to Gilead Sciences, Inc., a Delaware corporation (the “Company”), in connection with the Underwriting Agreement, dated November 12, 2014 (the “Underwriting Agreement”), between you, as representatives of the several underwriters named therein (the “Underwriters”), and the Company, relating to the sale by the Company to the Underwriters of (a) $500,000,000 aggregate principal amount of the Company’s 2.350% Senior Notes due 2020 (the “2020 Notes”), (b) $1,750,000,000 aggregate principal amount of the Company’s 3.500% Senior Notes due 2025 (the “2025 Notes”) and (c) $1,750,000,000 aggregate principal amount of the Company’s 4.500% Senior Notes due 2045 (together with the 2020 Notes and the 2025 Notes, the “Securities”) to be issued under the Indenture, dated as of March 30, 2011 (the “Base Indenture”) and as supplemented by the Fourth Supplemental Indenture, dated as of November 17, 2014 (the “Fourth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and Xxxxx Fargo Bank, National Association, as trustee (the “Trustee”).

This opinion is being furnished to you pursuant to Section 6(g) of the Underwriting Agreement.

In rendering the opinions stated herein, we have examined and relied upon the following:

(a) the registration statement on Form S-3 (File No. 333-194298) of the Company relating to the Securities and other securities of the Company filed with the Securities and Exchange Commission (the “Commission”) on March 4, 2014 under the Securities Act of 1933, as amended (the “Securities Act”) allowing for delayed offerings pursuant to Rule 415 of the General Rules and Regulations under the Securities Act (the “Rules and Regulations”), including information deemed to be a part of the registration statement pursuant to Rule 430B of the Rules and Regulations (such registration statement, including the Incorporated Documents (as defined below), being hereinafter referred to as the “Registration Statement”);

(b) the prospectus, dated March 4, 2014 (the “Base Prospectus”), which forms a part of and is included in the Registration Statement;

(c) the preliminary prospectus supplement, dated November 12, 2014 (together with the Base Prospectus and the Incorporated Documents, the “Preliminary Prospectus”), relating to the offering of the Securities, in the form filed by the Company pursuant to Rule 424(b) of the Rules and Regulations;

(d) the prospectus supplement, dated November 12, 2014 (together with the Base Prospectus and the Incorporated Documents, the “Prospectus”), relating to the offering of the Securities, in the form filed by the Company pursuant to Rule 424(b) of the Rules and Regulations;

(e) the documents described on Schedule A hereto filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934 and incorporated by reference into the Prospectus, as of the date hereof, or the Preliminary Prospectus, as of the date of the Underwriting Agreement (collectively, the “Incorporated Documents”);

(f) an executed copy of the Underwriting Agreement;

(g) the global certificates evidencing the Securities (the “Note Certificates”) in the form delivered by the Company to the Trustee for authentication and delivery;

(h) an executed copy of the Base Indenture;

(i) an executed copy of the Fourth Supplemental Indenture;

(j) an executed copy of a certificate of Xxxxx X. Xxxxxxxxxx, Executive Vice President and Chief Financial Officer of the Company, and Xxxxx Xxxxxxxx, Senior Vice President, General Counsel and Assistant Secretary of the Company, dated the date hereof, a copy of which is attached as Exhibit A hereto (the “Officers’ Certificate”);

(k) an executed copy of a certificate of Xxxxx Xxxxxxxx, Assistant Secretary of the Company, dated the date hereof (the “Secretary’s Certificate”);

(l) a copy of the Company’s restated certificate of incorporation and a copy of the Company’s amendment to certificate of incorporation, certified by the Secretary of State of the State of Delaware as of [—], 2014, and certified pursuant to the Secretary’s Certificate;

(m) a copy of the Company’s bylaws, as amended and in effect as of the date hereof, certified pursuant to the Secretary’s Certificate;

(n) copies of certain resolutions of the Board of Directors of the Company, adopted on [—], 2014, and certain resolutions of the Offering Committee thereof, adopted on [—], 2014, each certified pursuant to the Secretary’s Certificate;

(o) an executed copy of a pricing certificate of Xxxxx X. Xxxxxxxxxx, Chief Financial Officer of the Company, dated [—], 2014;

(p) a copy of a certificate, dated [—], 2014, and a bringdown verification thereof, dated the date hereof, from the Secretary of State of the State of Delaware with respect to the Company’s existence and good standing in the State of Delaware (collectively, the “Delaware Certificate”);

(q) a copy of a certificate, dated [—], 2014, and a bringdown verification thereof, dated [—], 2014, from the Secretary of State of the State of California as to the qualification of the Company to transact intrastate business in such jurisdiction (the “Foreign Qualification Certificate”); and

(r) the Scheduled Contracts (as defined below).

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions stated below.

In our examination, we have assumed the genuineness of all

signatures, including endorsements, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinions stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials, including the facts and conclusions set forth in the Officers’ Certificate.

We do not express any opinion with respect to the laws of any jurisdiction other than (i) the laws of the State of New York, (ii) the federal laws of the United States of America and (iii) the General Corporation Law of the State of Delaware (the “DGCL”).

The Underwriting Agreement, the Note Certificates and the Indenture are referred to herein collectively as the “Transaction Agreements.” As used herein: “Organizational Documents” means those documents listed in paragraphs (l) and (m) above. “Scheduled Contracts” means those agreements or instruments described on Schedule B hereto. “Scheduled Orders” means those orders or decrees described on Schedule C hereto. “General Disclosure Package” means the Preliminary Prospectus as amended and supplemented by the document identified on Schedule D hereto.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that:

1. Based solely on our review of the Delaware Certificate, the Company is duly incorporated and is validly existing and in good standing under the DGCL.

2. Based solely on our review of the Foreign Qualification Certificate, the Company is qualified to transact intrastate business in the State of California, as of the latest date identified on the Foreign Qualification Certificate.

3. The Company has the corporate power and authority under the DGCL to conduct its business and own and lease its properties, in each case as described in the Prospectus, and to execute and deliver each of the Transaction Agreements and to consummate the issuance and sale of the Securities contemplated thereby.

4. Each of the Underwriting Agreement and the Indenture has been duly authorized, executed and delivered by all requisite corporate action on the part of the Company under the DGCL.

5. The Indenture constitutes the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms under the laws of the State of New York.

6. Neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the issuance and sale of the Securities contemplated thereby: (i) conflicts with the Organizational Documents, (ii) constitutes a violation of, or a default under, any Scheduled Contract, (iii) contravenes any Scheduled Order or (iv) violates the DGCL or any law, rule or regulation of the State of New York or the United States of America.

7. Neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the issuance and sale of the Securities contemplated thereby requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of the State of New York or the United States of America except for those consents, approvals, licenses and authorizations already obtained and those filings, recordings and registrations already made.

8. The Note Certificates have been duly authorized by all requisite corporate action on the part of the Company and duly executed by the Company under the DGCL, and when duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Note Certificates will constitute valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms under the laws of the State of New York.

9. The Company is not and, solely after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectus, will not be an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

10. The statements in the Prospectus and the General Disclosure Package under the captions “Description of Debt Securities” and “Description of the Notes” other than under the caption “Book-Entry; Delivery and Form of Notes,” insofar as such statements purport to summarize certain provisions of the Indenture and the Note Certificates, fairly summarize such provisions in all material respects.

The opinions stated herein are subject to the following qualifications:

(a) the opinions stated herein are limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

(b) except to the extent expressly stated in the opinions contained herein with respect to the Company, we do not express any opinion with respect to the effect on the opinions stated herein of (i) the compliance or non-compliance of any party to any of the Transaction Agreements with any laws, rules or regulations applicable to such party or (ii) the legal status or legal capacity of any party to any of the Transaction Agreements;

(c) except to the extent expressly stated in the opinions contained herein with respect to the Company, we do not express any opinion with respect to any law, rule or regulation that is applicable to any party to any of the Transaction Agreements or the transactions contemplated thereby solely because such law, rule or regulation is part of a regulatory regime applicable to any such party or any of its affiliates as a result of the specific assets or business operations of such party or such affiliates;

(d) except to the extent expressly stated in paragraph 9 above, we do not express any opinion with respect to any securities, antifraud, derivatives or commodities laws, rules or regulations or Regulations T, U or X of the Board of Governors of the Federal Reserve System;

(e) except to the extent expressly stated in the opinions contained herein with respect to the Company, we have assumed that each of the Transaction Agreements (other than the Underwriting Agreement) constitutes the valid and binding obligation of each party to such Transaction Agreement, enforceable against such party in accordance with its terms;

(f) except to the extent expressly stated in the opinions contained herein, the opinions stated herein are limited to the agreements specifically identified herein without regard to any agreement or other document referenced in such agreement (including agreements or other documents incorporated by reference or attached or annexed thereto);

(g) we do not express any opinion with respect to whether the execution or delivery of any Transaction Agreement by the Company, or the performance by the Company of its obligations under any Transaction Agreement, will constitute a violation of, or a default under, any covenant, restriction or provision with respect to financial ratios or tests or any aspect of the financial condition or results of operations of the Company or any of its subsidiaries;

(h) we do not express any opinion with respect to the enforceability of any provision contained in any Transaction Agreement relating to any indemnification, contribution, exculpation or waiver that may be contrary to public policy or violative of federal or state securities laws;

(i) to the extent that any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions contained in any Transaction Agreement, the opinions stated herein are subject to the qualification that such enforceability may be subject to, in each case, (i) the exceptions and limitations in New York General Obligations Law sections 5-1401 and 5-1402 and (ii) principles of comity or constitutionality; and

(j) we call to your attention that irrespective of the agreement of the parties to any Transaction Agreement concerning personal jurisdiction over them, a court may decline to hear a case on grounds of forum non conveniens or other doctrine limiting the availability of such court as a forum for resolution of disputes; in addition, we call to your attention that we do not express any opinion with respect to the subject matter jurisdiction of the federal courts of the United States of America in any action arising out of or relating to any Transaction Agreement.

In addition, in rendering the foregoing opinions we have assumed that:

(a) except to the extent expressly stated in the opinions contained herein with respect to the Company, neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the transactions contemplated thereby, including the issuance and sale of the Securities: (i) constitutes or will constitute a violation of, or a default under, any lease, indenture, instrument or other agreement to which the Company or its property is subject, (ii) contravenes or will contravene any order or decree of any governmental authority to which the Company or its property is subject, (iii) violates or will violate any law, rule or regulation to which the Company or its property is subject or (iv) requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of any jurisdiction; and

(b) in rendering the opinion set forth in paragraph 8 above, we have assumed that the Trustee’s certificates of authentication of the Note Certificates will have been manually signed by one of the Trustee’s authorized officers.

the Underwriting Agreement. Without our prior written consent, this opinion may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert the rights of an Underwriter in respect of this opinion (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

Very truly yours,

We have acted as special counsel to Gilead Sciences, Inc., a Delaware corporation (the “Company”), in connection with the Underwriting Agreement, dated November 12, 2014 (the “Underwriting Agreement”), between you, as representatives of the several underwriters named therein (the “Underwriters”), and the Company, relating to the sale by the Company to the Underwriters of (a) $500,000,000 aggregate principal amount of the Company’s 2.350% Senior Notes due 2020 (the “2020 Notes”), (b) $1,750,000,000 aggregate principal amount of the Company’s 3.500% Senior Notes due 2025 (the “2025 Notes”) and (c) $1,750,000,000 aggregate principal amount of the Company’s 4.500% Senior Notes due 2045 (together with the 2020 Notes and the 2025 Notes, the “Securities”) to be issued under the Indenture, dated as of March 30, 2011 (the “Base Indenture”), and as supplemented by the Fourth Supplemental Indenture, dated as of November 17, 2014 (together with the Base Indenture, the “Indenture”), between the Company and Xxxxx Fargo Bank, National Association, as trustee.

This letter is being furnished to you pursuant to Section 6(g) of the Underwriting Agreement.

In the above capacity, we have reviewed the registration statement on Form S-3 (File No. 333-194298) of the Company relating to the Securities and other securities of the Company filed on March 4, 2014 with the Securities and Exchange

Commission (the “Commission”) under the Securities Act of 1933 (the “Securities Act”) allowing for delayed offerings pursuant to Rule 415 of the General Rules and Regulations under the Securities Act (the “Rules and Regulations”) including the Incorporated Documents (as defined below) and the information deemed to be a part of the registration statement pursuant to Rule 430B of the Rules and Regulations (such registration statement being hereinafter referred to as the “Registration Statement”), and (i) the prospectus, dated March 4, 2014 (the “Base Prospectus”), which forms a part of and is included in the Registration Statement, (ii) the preliminary prospectus supplement, dated November 12, 2014 (together with the Base Prospectus and the Incorporated Documents, the “Preliminary Prospectus”), relating to the offering of the Securities in the form filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations and (iii) the prospectus supplement, dated November 12, 2014 (the “Prospectus Supplement” and, together with the Base Prospectus and the Incorporated Documents, the “Prospectus”), relating to the offering of the Securities in the form filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations. We also have reviewed the documents identified on Schedule A hereto filed by the Company pursuant to the Securities Exchange Act of 1934 and incorporated by reference into the Prospectus or the Preliminary Prospectus, as the case may be, as of the date hereof or as of the Applicable Time (as defined below), respectively (collectively, the “Incorporated Documents”), the “issuer free writing prospectus” (as defined in Rule 433(h)(1) of the Rules and Regulations) identified on Schedule B hereto relating to the Securities (the “Free Writing Prospectus”) and such other documents as we deemed appropriate. Assuming the accuracy of the representations and warranties of the Company set forth in Section 2(d) and 2(gg) of the Underwriting Agreement, the Registration Statement became effective upon filing with the Commission pursuant to Rule 462 of the Rules and Regulations and, pursuant to Section 309 of the Trust Indenture Act of 1939, the Indenture has been qualified under the Trust Indenture Act of 1939, and to our knowledge, based solely upon our review of the Commission’s website, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

In addition, we have participated in conferences with officers and other representatives of the Company, representatives of the independent registered public accountants of the Company, representatives of the Underwriters, and counsel for the Underwriters at which the contents of the Registration Statement, the Prospectus, the Disclosure Package (as defined below) and related matters were discussed. We did not participate in the preparation of the Incorporated Documents but have, however, reviewed such documents and discussed the business and affairs of the Company with officers and other representatives of the Company. We do not pass upon, or assume any responsibility for, the accuracy, completeness or fairness

of the statements contained or incorporated by reference in the Registration Statement, the Prospectus or the Disclosure Package and have made no independent check or verification thereof (except to the limited extent referred to in (i) paragraph 10 of our opinion to you dated the date hereof and (ii) our opinion to you dated the date hereof regarding tax matters described under the caption “Certain United States Federal Income Tax Considerations” in the Prospectus).

On the basis of the foregoing, (i) the Registration Statement, at the Effective Time (as defined below), and the Prospectus, as of the date of the Prospectus Supplement, appeared on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the Rules and Regulations (except that in each case we do not express any view as to the financial statements, schedules and other financial information included or incorporated by reference therein or excluded therefrom or the Statement of Eligibility on Form T-1 (the “Form T-1”)) and (ii) no facts have come to our attention that have caused us to believe that the Registration Statement, at the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as of the date of the Prospectus Supplement and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that in each case we do not express any view as to the financial statements, schedules and other financial information included or incorporated by reference therein or excluded therefrom, the report of management’s assessment of the effectiveness of internal controls over financial reporting or the auditors’ report on the effectiveness of the Company’s internal controls over financial reporting, or the statements contained in the exhibits to the Registration Statement, including the Form T-1). In addition, on the basis of the foregoing, no facts have come to our attention that have caused us to believe that the Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that we do not express any view as to the financial statements, schedules and other financial information included or incorporated by reference therein or excluded therefrom, the report of management’s assessment of the effectiveness of internal controls over financial reporting or the auditors’ report on the effectiveness of the Company’s internal controls over financial reporting, or the statements contained in the exhibits to the Registration Statement, including the Form T-1, to the extent included or incorporated by reference therein).

As used herein, (i) “Effective Time” means the time of effectiveness of the Registration Statement for purposes of Section 11 of the Securities Act, as

such section applies to the Underwriters, (ii) “Applicable Time” means 4:00 p.m. (Eastern time) on November 12, 2014 and (iii) “Disclosure Package” means the Preliminary Prospectus, as amended and supplemented by the Free Writing Prospectus.

This letter is furnished only to you as representatives of the Underwriters and is solely for the Underwriters’ benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Without our prior written consent, this letter may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert the rights of an Underwriter in respect of this letter (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

Very truly yours,

Re: Gilead Sciences, Inc. – Offering of Senior Notes

Ladies and Gentlemen:

I am the Senior Vice President and General Counsel of Gilead Sciences, Inc., a Delaware corporation (the “Company”), and have served as counsel to the Company in connection with the Underwriting Agreement, dated as of November 12, 2014 (the “Underwriting Agreement”), between you, as representatives of the several underwriters named therein (the “Underwriters”), and the Company, relating to the sale by the Company to the Underwriters of (a) $500,000,000 aggregate principal amount of the Company’s 2.350% Senior Notes due 2020 (the “2020 Notes”), (b) $1,750,000,000 aggregate principal amount of the Company’s 3.500% Senior Notes due 2025 (the “2025 Notes”) and (c) $1,750,000,000 aggregate principal amount of the Company’s 4.500% Senior Notes due 2045 (the “2045 Notes” and, together with the 2020 Notes and the 2025 Notes, the “Securities”) to be issued under the Indenture, dated as of March 30, 2011 (the “Base Indenture”), as supplemented prior to the date hereof and as supplemented by the Fourth Supplemental Indenture, dated as of November 17, 2014 (the “Fourth Supplemental Indenture” and, together with the Base Indenture, as supplemented prior to the date hereof, the “Indenture”), between the Company and Xxxxx Fargo Bank, National Association, as trustee (the “Trustee”).

This letter is being furnished to you pursuant to Section 6(h) of the Underwriting Agreement.

As such counsel, I have examined such matters of fact and questions of law as I have considered appropriate for purposes of this letter. I have examined, among other things, the following:

the General Rules and Regulations under the Securities Act (the “Rules and Regulations”), including information deemed to be a part of the registration statement pursuant to Rule 430B of the Rules and Regulations (such registration statement, including the Incorporated Documents (as defined below), being hereinafter referred to as the “Registration Statement”)

(b) the prospectus, dated March 4, 2014 (the “Base Prospectus”), which forms a part of and is included in the Registration Statement;

(c) the prospectus supplement, dated November 12, 2014 (together with the Base Prospectus and the Incorporated Documents, the “Prospectus”), relating to the offering of the Securities, in the form filed by the Company pursuant to Rule 424(b) of the Rules and Regulations;

(d) the documents described on Schedule A hereto filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934 and incorporated by reference into the Prospectus, as of the date hereof (collectively, the “Incorporated Documents”);

(e) an executed copy of the Underwriting Agreement;

(f) an executed copy of the Base Indenture;

(g) an executed copy of the Fourth Supplemental Indenture;

(h) the global certificates evidencing the Securities in the form delivered by the Company to the Trustee for authentication and delivery;

(i) the written agreements of the Company listed on Exhibit A (the “Identified Documents”); and

(j) such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as I have deemed necessary or advisable to enable me to render these opinions.

The documents described under the foregoing clauses (e) through (h) are referred to herein as the “Transaction Documents.”

As to facts material to the opinions, statements and assumptions expressed herein, I have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company and others, including the representations and warranties of the Company in the Underwriting Agreement. I have not independently verified such factual matters.

I am opining herein as to the effect on the subject transaction only of the federal laws of the United States and the internal laws of the State of California, and I express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or as to any matters of municipal law or the laws of any local agencies within any state. My opinions and confirmations herein are based upon my consideration of only those statutes, rules and regulations which, in my experience, are normally applicable to private

offerings of debt securities. Various matters concerning the offering of the Securities are addressed in the opinions and negative assurances letter of Xxxxxxx, Arps, Slate, Xxxxxxx & Xxxx LLP, which have been separately provided to you. I express no opinion with respect to those matters.

Whenever a statement in this letter is qualified by “to the best of my knowledge” or a similar phrase, it is intended to indicate that I and the other attorneys of the Company do not have current actual knowledge of the inaccuracy of such statement. However, except as otherwise indicated, I have not undertaken any independent investigation to determine the accuracy of any such statement, and no inference as to my knowledge of any matters pertaining to such statement should be drawn from my representation of the Company. Whenever a statement in this letter is made regarding action taken by me and/or my participation in activities, such references include actions taken and/or participation by attorneys at the Company under my supervision.

Subject to the foregoing and the other matters set forth herein, it is my opinion that, as of the date hereof:

1. The Incorporated Documents (other than the financial statements and the notes thereto, schedules and other financial data included in, incorporated by reference in or omitted from the Prospectus, as to which I express no opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder as in effect at the time of their respective filings.

2. To the best of my knowledge, the statements in the “Legal Proceedings” section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, giving effect to Rule 412 of the Securities Act, as amended, insofar as such statements constitute summaries of the legal matters or proceedings referred to therein, are accurate in all material respects, and to the best of my knowledge, there are no other legal or governmental proceedings pending or threatened, to which the Company is a party or to which any of the properties of the Company is subject that are required to be described in the Prospectus or incorporated by reference therein which are not so described or incorporated by reference.

3. The execution and delivery by the Company of the Transaction Documents and the issuance and sale of the Securities by the Company to the Underwriters pursuant to the Underwriting Agreement on the date hereof do not contravene any of the Identified Documents.

In rendering the opinion in paragraph 3 insofar as it requires interpretation of the Identified Documents, with your consent, (i) I have assumed that courts of competent jurisdiction would enforce such agreements in accordance with their plain meaning, (ii) to the extent that any questions of legality or legal construction have arisen in connection with my review, I have applied the laws of the State of California in resolving such questions, although the agreements or instruments binding upon the Company may be governed by other laws which differ from California law, (iii) I express no opinion with respect to the effect of any discretionary action or inaction by the Company under Identified Documents that may result in a breach or default

under such agreements or instruments, and (iv) I express no opinion with respect to any matters which would require me to perform a mathematical calculation or make a financial or accounting determination.

This opinion is furnished only to you as representatives of the Underwriters and is solely for the Underwriters’ benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Without my prior written consent, this opinion may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert your rights in respect of this opinion (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

Very truly yours,

Xxxxx Xxxxxxxx

Senior Vice President and General Counsel
