Description of Registrant's Securities

The following description of the capital stock of Gilead Sciences, Inc. (“Gilead”) does not purport to be complete and is subject to, and qualified in its entirety by, our restated certificate of incorporation (“certificate”) and our amended and restated bylaws (“bylaws”), each of which is incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this exhibit is a part.

Our authorized capital stock consists of 5,600,000,000 shares of common stock, $0.001 par value, and 5,000,000 shares of preferred stock, $0.001 par value per share. We have one class of securities registered under Section 12 of the Securities Exchange Act of 1934, our common stock, which is listed on the Nasdaq Global Select Market under the symbol “GILD.”

Voting rights. The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. A majority of the votes cast is required for stockholders to elect directors (except that directors are elected by a plurality of the votes cast in a contested director election). All other matters put to a stockholder vote generally require the approval of a majority of the shares entitled to vote on the matter and present in person or represented by proxy, except for certain matters for which our certificate and bylaws require the approval of a majority of the voting power of the outstanding shares entitled to vote on the matter and except as otherwise required by law. Stockholders do not have cumulative voting rights.

Dividends. The holders of our common stock have the right to receive dividends if they are declared by our board of directors and there are sufficient funds to legally pay dividends, subject to the rights of the holders of any outstanding preferred stock to receive preferential dividends.

Liquidation. Upon our liquidation, holders of our common stock would share ratably in any assets available for distribution to stockholders after payment of all of our obligations and the aggregate liquidation preference (including accrued and unpaid dividends) of any outstanding preferred stock.

Preemptive, subscription and conversion rights. Our common stock is not redeemable and has no preemptive, subscription or conversion rights.

Transfer agent. The transfer agent and registrar for our common stock is Computershare.

The rights, preferences and privileges of holders of our common stock are subject to the rights of the holders of shares of any series of preferred stock which we may issue.

Our board of directors has the authority, without further action by our stockholders, to issue up to 5,000,000 shares of preferred stock, none of which are outstanding. Our board of directors may issue preferred stock in one or more series and fix the rights, preferences, privileges and restrictions of such preferred stock, including:

The issuance of preferred stock could decrease the amount of earnings and assets available for distribution to the holders of our common stock or adversely affect the rights and powers, including voting rights, of the holders of our common stock.

Some provisions of our certificate of incorporation, bylaws and Delaware law may have the effect of delaying, deferring or discouraging another party from acquiring control of us.

Our certificate and bylaws provide that:

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law (“DGCL”). In general, the statute prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date that the person became an interested stockholder unless, with some exceptions, the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the stockholder, and an “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years prior, did own) 15% or more of the corporation’s outstanding voting stock. This provision may have the effect of delaying, deferring or preventing a change in control without further action by the stockholders.

Our certificate provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of Gilead or our stockholders; (iii) any action asserting a claim against us arising pursuant to any provision of the DGCL, or our restated certificate of incorporation or our amended and restated bylaws; or (iv) any action asserting a claim against us or any of our directors, officers, employees or agents governed by the internal affairs doctrine; provided, however, that in the event the Court of Chancery of the State of Delaware lacks jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall be another state or federal court located within the State of Delaware. Our certificate also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and to have consented to this choice of forum provision. It is possible that a court of law could rule that the choice of forum provision contained in our restated certificate of incorporation is inapplicable or unenforceable if it is challenged in a proceeding or otherwise.
