PROPOSAL 1

ELECTION OF DIRECTORS

There are eight nominees for the eight Board of Directors positions presently authorized by resolution of the Board.

PROPOSAL 2

APPROVAL OF THE AMENDED AND RESTATED 1991 STOCK OPTION PLAN

In November 1991, the Board adopted, and the stockholders subsequently approved, the Company's 1991 Stock Option Plan (the "1991 Plan"). In January 2002, the Board adopted an amendment to the 1991 Plan subject to stockholder approval (the "Restated 1991 Plan") and reserved an additional 6,000,000 shares of Common Stock on a split-adjusted basis for issuance under the Restated 1991 Plan, bringing the total shares authorized for issuance thereunder to 53,000,000. The Board adopted this amendment to enable the Company to continue to grant stock options to employees at levels that the Board and the Compensation Committee deem to be appropriate. The Board intends to increase the shares available for issuance under the Restated 1991 Plan on an annual basis in amounts approximating the number of shares required for the options the Company anticipates granting over the subsequent year.

As of February 28, 2002, options (net of canceled or expired options) to purchase an aggregate of 37,884,651 shares of Common Stock had been granted under the Restated 1991 Plan and 15,115,349 shares (plus any shares that might in the future be returned as a result of the cancellation or expiration

of options) remained available for future grants under the Restated 1991 Plan. During 2001, under the 1991 Plan, the Company granted the following:

•: options to purchase 904,000 shares at exercise prices ranging from $14.7969 to $19.6200 per share to all current executive officers, as a group;
•: options to purchase 5,332,860 shares at exercise prices ranging from $13.5813 to $34.3250 per share to all employees, other than executive officers, as a group; and
•: no options to current directors who are not officers.

For information regarding stock option grants to the Company's Chief Executive Officer and its four other most highly compensated executive officers for the year ended December 31, 2001 (the "Named Executive Officers"), see "Executive Compensation-Stock Option Grants and Exercises."

Stockholders are requested in this proposal to approve the amendment of the 1991 Plan as the Restated 1991 Plan in the form attached hereto as Exhibit B. This amendment involves reserving for issuance an additional 6,000,000 shares of Common Stock. If the stockholders fail to approve this proposal, the 1991 Plan will continue in the form prior to the amendment.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting will be required to approve the Restated 1991 Plan. Abstentions will be counted towards the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

THE BOARD RECOMMENDS A VOTE FOR PROPOSAL 2.

The essential features of the Restated 1991 Plan are outlined below:

General

The Restated 1991 Plan provides for the grant of both incentive stock options and nonstatutory stock options. Incentive stock options granted under the Restated 1991 Plan are intended to qualify as "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code. Nonstatutory stock options granted under the Restated 1991 Plan are intended not to qualify as incentive stock options under the Internal Revenue Code. See "Federal Income Tax Information" for a discussion of the tax treatment of the options included in the Restated 1991 Plan.

Purpose

The Restated 1991 Plan was adopted to provide a means:

•: by which selected directors and employees of, and consultants to, the Company and its affiliates could be given an opportunity to acquire stock in the Company;
•: to secure and retain the services of persons capable of filling such positions;
•: to assist in retaining the services of employees holding key positions; and
•: to provide incentives for such persons to exert maximum efforts for the success of the Company and its affiliates.

Administration

The Board administers the Restated 1991 Plan unless and until the Board delegates administration to a committee. Under the Restated 1991 Plan, the committee may consist of one or more non-employee members of the Board.

The Board delegated primary administration of the Restated 1991 Plan to the Compensation Committee of the Board, and on October 25, 2001 delegated to the Chief Executive Officer of the Company the authority to grant stock options to certain eligible employees of the Company. In connection with the administration of the Restated 1991 Plan, the Compensation Committee generally has the powers possessed by the Board. However, the Compensation Committee's powers may be restricted by resolutions adopted by the Board, from time to time, so long as the resolutions are not inconsistent with the provisions of the Restated 1991 Plan. In this proposal, the "Board" refers to the Compensation Committee as well as to the Board.

The Board has delegated to the Company's Chief Executive Officer the authority to grant options to eligible persons who are not then subject to Section 16 of the Exchange Act and/or who are either:

•: not then employees covered by Section 162(m) of the Internal Revenue Code and are not expected to be covered by Section 162(m) of the Internal Revenue Code at the time of recognition of income resulting from such option; or
•: not persons with respect to whom the Company wishes to avoid the application of Section 162(m) of the Internal Revenue Code.

The Board may at any time return the administration of the Restated 1991 Plan to the Board.

The Board, or a committee as the case may be, generally has the power to construe and interpret the Restated 1991 Plan. In addition, subject to the provisions of the Restated 1991 Plan, the Board has the power to determine the following:

•: the persons to whom and the dates on which options will be granted;
•: what type of option will be granted;
•: the number of shares to be subject to each option;
•: the time or times during the term of each option within which all or a portion of the option may be exercised;
•: the exercise price;
•: the type of consideration; and
•: other terms of the option.

Shares Subject to the Restated 1991 Plan

The Common Stock that may be sold pursuant to options under the Restated 1991 Plan shall not exceed in the aggregate 53,000,000 shares of Common Stock. If any option expires or terminates, in whole or in part, without having been exercised in full, the stock not purchased under such option will become available again for issuance under the Restated 1991 Plan.

Eligibility

Incentive stock options may be granted only to employees. Nonstatutory stock options may be granted to employees, directors or consultants of both the Company and its affiliates. As of February 28, 2002, approximately 1,031 employees were eligible to participate in the Restated 1991 Plan.

Generally, a person who owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any affiliate of the Company will not be eligible for the grant of an incentive stock option. However, such 10% stockholder may be granted an incentive stock option if: (1) the exercise price of the option is at least 110% of the fair market value of the Common

Stock subject to the option on the option's date of grant; and (2) the term of the option does not exceed five years from the date of grant. No person is eligible to be granted options covering more than 2,000,000 shares of Common Stock in any calendar year.

Term and Termination

No option is exercisable after the expiration of 10 years from the date it was granted.

In the event that an optionee's continuous service to the Company or its affiliates is terminated, the optionee's ability to exercise his or her option is restricted. In such a case, the optionee may exercise his or her option, to the extent that he or she was entitled to exercise it at the time of termination, but only within the earlier of (1) the period of time after the termination of the optionee's continuous service specified in the option agreement or (2) the expiration of the term of the option as specified in the option agreement. In the case of an incentive stock option, if such period of time exceeds three months from the date of termination except in the event of death or disability, the option will be taxed as a non-statutory stock option.

In the event an optionee's continuous service to the Company or its affiliates terminates as a result of the optionee's death or disability, the ability of the optionee or such optionee's estate, heirs or beneficiaries to exercise his or her option is restricted. In such a case, the option may be exercised, but only within the period ending on the earlier of (1) twelve months following such termination or such longer or shorter period as specified in the option agreement or (2) the expiration of the term of the option as specified in the option agreement.

The option term generally is not extended in the event that exercise of the option within these periods is prohibited. An optionee's option agreement may provide that if the exercise of the option following the termination of the optionee's service would result in liability under Section 16(b) of the Exchange Act, then the option shall terminate on the earlier of (i) the expiration of the term of the option or (ii) the tenth day after the last date on which such exercise would result in such liability under Section 16(b). An optionee's option agreement also may provide that if the exercise of the option following the termination of the optionee's service would be prohibited because the issuance of stock would violate the registration requirements under the Securities Act of 1933, as amended (the "Securities Act"), then the option will terminate on the earlier of (i) the expiration of the term of the option or (ii) 90 days after the termination of the optionee's service during which the exercise of the option would not be in violation of such registration requirements.

Exercise Price

The exercise price of each incentive stock option and each nonstatutory stock option granted under the Restated 1991 Plan will not be less than 100% of the fair market value of the Company's Common Stock on the date of grant. If options were granted with exercise prices below market value, deductions for compensation attributable to the exercise of such options could be limited by Section 162(m) of the Code. See "Federal Income Tax Information." Under the Code, the exercise price of incentive stock options (see "Eligibility" above) may not be less than 110% of the fair market value of the Company's Common Stock on the date of grant.

As of February 28, 2002, the closing price of the Company's Common Stock as reported by The Nasdaq Stock Market was $35.23. The Company is prohibited from repricing outstanding options granted under the Restated 1991 Plan without the consent of its stockholders.

Payment of Exercise Price

The option's exercise price is paid either:

•: in cash at the time of exercise or purchase; or

•: if determined by the Board at the time of grant, by (1) deferred payment or other arrangement or (2) in any other form of legal consideration that may be acceptable to the Board, such as by delivery to the Company of other Common Stock of the Company.

In the case of any deferred payment arrangement, interest will be compounded at least annually. Interest will be charged at the minimum rate of interest necessary to avoid imputed interest for federal tax purposes.

Transferability

An incentive stock option is not transferable except by will or by the laws of descent and distribution. Moreover, an incentive stock option is exercisable during the lifetime of the person to whom the incentive stock option is granted only by such person. A nonstatutory stock option generally will not be transferable except by will or by the laws of descent and distribution. In addition, an optionee may designate a beneficiary who may exercise his or her option after death.

Vesting

Options granted under the Restated 1991 Plan may become exercisable in monthly, quarterly or other periodic installments. The option agreement may provide that from time to time during each of such installment periods, the option may become exercisable or vest with respect to some or all of the shares allotted to that period. In addition, it may provide that the option may be exercised with respect to some or all of the shares allotted to such period or any prior period as to which the option became vested but was not fully exercised. The option agreement may also provide that an optionee may exercise an option prior to full vesting, so long as the Company has a repurchase right with respect to any unvested shares.

Adjustments upon Changes in Stock

If any change is made in the Common Stock subject to the Restated 1991 Plan, or subject to any option, without receipt of cash or other property by the Company through:

•: merger, consolidation, reorganization, recapitalization;
•: stock dividend, dividend in property other than cash, stock split, liquidating dividend; or
•: combination of shares, exchange of shares, change in corporate structure or otherwise,

the class(es) and maximum number of shares subject to the Restated 1991 Plan, the maximum annual grant of shares under the Restated 1991 Plan and the class(es) and number of shares and price per share of stock subject to outstanding options will be appropriately adjusted.

In the event of:

•: a dissolution or liquidation of the Company;
•: a sale of all or substantially all of the assets of the Company;
•: a merger or consolidation in which the Company is not the surviving corporation;
•: a reverse merger in which the Company is the surviving corporation but the shares of the Company's Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or
•: any other capital reorganization in which more than 50% of the shares of the Company entitled to vote are exchanged

(collectively, a "change in control"),

then, at the discretion of the Board and to the extent permitted by applicable law, either (1) the surviving corporation will assume outstanding options or will substitute similar options for those outstanding under the Restated 1991 Plan, (2) the time during which such options may be exercised will be accelerated and the options terminated if not exercised prior to such event or (3) the options will continue in full force and effect.

If, within one month before or thirteen months after the date of a change in control, the continuous service of an optionee terminates due to an involuntary termination (not including death or disability) without "cause" (as such term is defined in the Restated 1991 Plan) or a voluntary termination by the optionee due to a "constructive termination" (as such term is defined in the Restated 1991 Plan), then the vesting and exercisability of all options held by that optionee will be accelerated or any reacquisition or repurchase rights held by the Company with respect to the option will lapse.

In the event that such acceleration of the vesting and exercisability of the options (or lapse of reacquisition or repurchase rights held by the Company with respect to options) as described above, when added to the benefits otherwise payable to an optionee, constitute "parachute payments" within the meaning of Section 280G of the Internal Revenue Code that would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code, then the optionee's benefits will be delivered to such lesser extent that will result in no portion of the benefits being subject to the excise tax.

Amendment of the Restated 1991 Plan

The Board at any time, and from time to time, may make further amendments to the Restated 1991 Plan. However, no amendment will be effective unless approved by the stockholders within twelve months before or after the adoption of the amendment, where the amendment will:

•: increase the number of shares reserved for issuance under the Restated 1991 Plan;
•: modify the requirements as to eligibility for participation; or
•: require stockholder approval in order for the Restated 1991 Plan to satisfy the requirements of Section 422 of the Internal Revenue Code, Rule 16b-3 promulgated under the Exchange Act or any securities exchange requirements.

The Board may in its sole discretion submit any other amendment to the Restated 1991 Plan for stockholder approval.

Termination or Suspension of the Restated 1991 Plan

The Board may suspend or terminate the Restated 1991 Plan at any time. Unless sooner terminated, the Restated 1991 Plan will terminate on April 30, 2010. No options may be granted under the Restated 1991 Plan while the Restated 1991 Plan is suspended or after it is terminated.

Federal Income Tax Information

The following describes the material federal income tax consequences to an optionee and the Company associated with the grant and exercise of options under the Restated 1991 Plan. This discussion does not purport to be complete and does not discuss the income tax laws of any state or foreign country in which an optionee may reside.

Incentive Stock Options

Incentive stock options under the Restated 1991 Plan are intended to be eligible for the favorable federal income tax treatment applicable to "incentive stock options" under the Internal Revenue Code.

There generally are no federal income tax consequences to the optionee or the Company by reason of the grant or exercise of an incentive stock option. However, the exercise of an incentive stock option may increase the optionee's alternative minimum tax liability, if any.

If an optionee holds stock acquired through exercise of an incentive stock option for (1) more than two years from the date on which the option is granted and (2) more than one year from the date on which the shares are transferred to the optionee upon exercise of the option, any gain or loss on a disposition of such stock will be capital gain or loss.

The disposition of the stock before the expiration of either of these holding periods is generally referred to as a "disqualifying disposition." A disqualifying disposition generally results in the optionee realizing taxable ordinary income equal to the lesser of (1) the excess of the stock's fair market value on the date of exercise over the exercise price, or (2) the optionee's actual gain, if any, on the purchase and sale. The optionee's additional gain, or any loss, upon the disqualifying disposition will be a capital gain or loss. The capital gain or loss will be long-term or short-term depending on whether the stock was held for more than one year.

Capital gains are generally subject to lower tax rates than ordinary income.

To the extent the optionee recognizes ordinary income by reason of a disqualifying disposition, the Company will generally be entitled to a corresponding business expense deduction in the tax year in which the disqualifying disposition occurs. The Company's ability to take this deduction will generally depend upon the satisfaction of the requirement of reasonableness, the provisions of Section 162(m) of the Internal Revenue Code and a tax reporting obligation.

Nonstatutory Stock Options

Nonstatutory stock options granted under the Restated 1991 Plan generally have the following federal income tax consequences.

There are no tax consequences to the optionee or the Company by reason of the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock option, the optionee normally will recognize taxable ordinary income. The ordinary income will generally be equal to the excess of the stock's fair market value on the date of exercise over the option exercise price.

Generally, the Company is required to withhold from regular wages or supplemental wage payments of employees an amount based on any ordinary income recognized. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Internal Revenue Code and the satisfaction of a reporting obligation, the Company will generally be entitled to a business expense deduction equal to the taxable ordinary income realized by the optionee.

Upon disposition of the stock, the optionee will recognize a capital gain or loss. The capital gain or loss will be equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon exercise of the option. Such gain or loss will be long-term or short-term depending on how long the optionee holds the stock.

Potential Limitation on the Company's Deductions

Section 162(m) of the Internal Revenue Code denies a deduction to any publicly held corporation for compensation paid to certain "covered employees" in a taxable year to the extent that compensation exceeds $1 million for a covered employee. It is possible that compensation attributable to options when combined with all other types of compensation received by a covered employee from the Company may cause this limitation to be exceeded in any particular year.

Certain kinds of compensation, including qualified "performance-based compensation" are disregarded for purposes of the deduction limitation. Under United States Treasury Regulations, compensation attributable to stock options will qualify as performance-based compensation, if the option is granted by a compensation committee comprised solely of "outside directors" and either:

•: (1) the option plan contains a per-employee limitation on the number of shares for which options may be granted during a specified period, (2) the per-employee limitation is approved by the stockholders, and (3) the exercise price of the option is no less than the fair market value of the stock on the date of grant; or
•: the option is granted or exercisable only upon the achievement, as certified in writing by the compensation committee, of an objective performance goal established in writing by the compensation committee while the outcome is substantially uncertain and the option is approved by stockholders.

PROPOSAL 3

APPROVAL OF THE AMENDED 1995 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

In November 1995, the Board adopted, and the stockholders subsequently approved, Gilead's 1995 Non-Employee Directors' Stock Option Plan (the "Directors' Option Plan"). In January 2002, the Board adopted an amendment to the Directors' Option Plan. The amendment increased the authorized shares under the Directors' Option Plan from 2,200,000 to 2,800,000 on a split-adjusted basis. Stockholders are requested in this proposal to approve the amendment to the Directors' Option Plan, as amended in the form attached hereto as Exhibit C. If the stockholders fail to approve this proposal, the Directors' Option Plan will continue in the form prior to the amendment. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting will be required to approve the Directors' Option Plan. Abstentions will be counted towards the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

THE BOARD RECOMMENDS A VOTE FOR PROPOSAL 3.

The essential features of the Directors' Option Plan are outlined below:

General

The Directors' Option Plan provides for non-discretionary grants of nonstatutory stock options, on an automatic basis pursuant to a pre-approved schedule. Options granted under the Directors' Option Plan are not intended to qualify as incentive stock options, as defined under Section 422 of the Internal Revenue Code.

Purpose

The purpose of the Directors' Option Plan is: (1) to retain the services of persons now serving as non-employee directors of Gilead, as defined below; (2) to attract and retain the services of persons capable of serving on the Board; and (3) to provide incentives for such persons to exert maximum efforts to promote the success of the Company.

Administration

The Directors' Option Plan is administered by the Board. The Board has the final power to construe and interpret the Directors' Option Plan and options granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board is authorized to delegate

administration of the Directors' Option Plan to a committee of not less than two members of the Board. The Board does not presently contemplate delegating administration of the Directors' Option Plan to any committee of the Board.

Shares Subject to the Non-Employee Directors' Stock Option Plan

The common stock that may be sold pursuant to options under the Directors' Option Plan shall not exceed in the aggregate 2,800,000 shares of Gilead Common Stock on a split-adjusted basis, after giving effect to the January 2002 amendment. If any option expires or terminates without having been exercised in full, the stock not purchased under such option will revert to and again become available for issuance under the Directors' Option Plan. The common stock subject to the Directors' Option Plan may be unissued shares or reacquired shares, bought on the market or otherwise.

Eligibility

The Directors' Option Plan provides that options may be granted only to non-employee directors of Gilead. A "non-employee director" is defined in the Directors' Option Plan as a director of Gilead and its affiliates who is not otherwise an employee of Gilead or any affiliate. All of Gilead's directors standing for election at the annual meeting, except for Dr. Martin, are eligible to participate in the Directors' Option Plan.

Terms and Conditions of Options

Each option under the Directors' Option Plan is subject to the following terms and conditions:

Non-Discretionary

Option grants under the Directors' Option Plan are non-discretionary. Each non-employee director shall, on the later of January 2, 1996 or the date he or she is first elected to be a non-employee director, be granted an option to purchase 100,000 shares of Gilead Common Stock as his or her initial grant. On each anniversary date of the non-employee director's initial grant, the non-employee director shall automatically be granted an option to purchase 15,000 shares of Gilead Common Stock as his or her annual grant. A non-employee director who is also the Chairperson of the Gilead Board of Directors, or designated by the Gilead Board of Directors as the "lead director" in circumstances where there is no Chairperson or the Chairperson is an employee of Gilead, will be granted an option to purchase an additional 80,000 shares of Gilead Common Stock at the time of his or her initial grant, and an additional 12,000 shares of Gilead Common Stock at the time of his or her annual grant. Each non-employee director who also serves on a standing committee of the Gilead Board of Directors shall automatically be granted an option to purchase an additional 4,000 shares of Gilead Common Stock at the time of his or her initial grant, and an additional 3,000 shares of common stock of the Company at the time of his or her annual grant, for each such committee. Each non-employee director who serves on a standing committee and who is also the Chairperson of that committee shall automatically be granted an option to purchase 8,000 shares at the time of his or her initial grant or later election as Chairperson and an additional 6,000 shares of Gilead Common Stock at the time of his or her annual grant. No other options may be granted under the Directors' Option Plan.

Transferability; Term

Under the Directors' Option Plan, an option may not be transferred by the optionee, except by will or the laws of descent and distribution, or pursuant to a domestic relations order. No option granted under the Directors' Option Plan is exercisable by any person after the expiration of ten years from the date the option is granted.

Option Exercise

An option granted under the Directors' Option Plan becomes exercisable or vests over a period of five years in equal quarterly installments at the rate of 5% per quarter. Such vesting is conditioned upon continued service as a non-employee director or employee of, or consultant to, Gilead.

Other Provisions

The option agreement may contain such other terms, provisions and conditions not inconsistent with the Directors' Option Plan as may be determined by the Board.

Exercise Price and Consideration

The exercise price of each option granted under the Directors' Option Plan will not be less than 100% of the fair market value of Gilead Common Stock on the date of grant. As of February 28, 2002, the closing price for Gilead Common Stock as reported by The Nasdaq Stock Market was $35.23. The exercise price of options granted under the Directors' Option Plan must be paid in cash, shares of Gilead Common Stock or pursuant to a broker-assisted exercise program at the time the option is exercised. Gilead is prohibited from repricing outstanding options granted under the Directors' Option Plan without the consent of Gilead's stockholders.

Adjustments Upon Changes in Stock

If any change is made in the common stock subject to the Directors' Option Plan, or subject to any option, without receipt of consideration by Gilead through:

•: merger, consolidation, reorganization, recapitalization;
•: stock dividend, dividend in property other than cash, stock split, liquidating dividend;
•: or combination of shares, exchange of shares, change in corporate structure or otherwise,

then the class(es) and maximum number of shares subject to the Directors' Option Plan, the maximum annual grant of shares under the Directors' Option Plan and the class(es) and number of shares and price per share of stock subject to outstanding options will be appropriately adjusted.

In the event of:

•: a dissolution or liquidation of the Company;
•: a merger or consolidation in which Gilead is not the surviving corporation;
•: a reverse merger in which Gilead is the surviving corporation but the shares of Gilead Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or
•: any other capital reorganization in which more than 50% of the shares of Gilead entitled to vote are exchanged

then, to the extent permitted by applicable law, the time during which such options may be exercised will be accelerated and the options terminated if not exercised prior to such event. The acceleration of an option in the event of an acquisition or similar corporate event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain control of Gilead.

Duration, Amendment and Termination

The Board may amend, suspend or terminate the Directors' Option Plan at any time or from time to time. However, the Board may not amend the Directors' Option Plan with respect to the amount, price or timing of grants more often than once every six months other than to comply with changes to the Internal Revenue Code or the Employee Retirement Income Security Act of 1974 or associated regulations. No amendment will be effective unless approved by the stockholders of Gilead within twelve months before or after its adoption by the Board if the amendment would: (1) increase the number of shares reserved for options under the plan; (2) modify the requirements as to eligibility for participation in the plan, to the extent such modification requires stockholder approval in order for the plan to comply with the requirements of Rule 16b-3; or (3) modify the plan in any other way if such modification requires stockholder approval in order for the plan to meet the requirements of Rule 16b-3 or any securities exchange requirements. Unless sooner terminated, the Directors' Option Plan will terminate on November 26, 2005.

Federal Income Tax Information

The following describes the material federal income tax consequences to an optionee and Gilead associated with the grant and exercise of options under the Directors' Option Plan. This discussion does not purport to be complete and does not discuss the income tax laws of any state or foreign country in which an optionee may reside. Options granted under the Directors' Option Plan are subject to federal income tax treatment applicable to options that are not incentive stock options. Options granted under the Directors' Option Plan are nonstatutory options. There are no tax consequences to the optionee or Gilead by reason of the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock option, the optionee normally will recognize taxable ordinary income equal to the excess of the stock's fair market value on the date of exercise over the option exercise price. Upon disposition of the stock, the optionee will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon exercise of such options. Such gain or loss will be long-term or short-term depending on whether the stock was held for more than one year.

PROPOSAL 4

RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITORS

The Board has selected Ernst & Young LLP as the Company's independent auditors for the fiscal year ending December 31, 2002 and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the Annual Meeting. The Audit Committee of the Board believes that the provision of services performed by Ernst & Young during 2001 was compatible with their independence. Ernst & Young LLP has audited the Company's financial statements since Gilead's inception in 1987. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

During the fiscal year ended December 31, 2001, Gilead incurred fees for the services of Ernst & Young LLP and its affiliates of approximately $806,000. These expenditures consisted in part of annual audit fees of $383,000. The Company also incurred $423,000 in additional fees including $237,000 in audit-related services such as reviews of registration statements filed with the Securities and Exchange Commission (the "SEC"), foreign subsidiary statutory audits and consultations on accounting matters. The remaining $186,000 in additional fees consisted principally of pension audits, internal audit services and consultations on tax matters. Ernst & Young did not perform any services related to financial information systems design and implementation.

Stockholder ratification of the selection of Ernst & Young LLP as Gilead's independent auditors is not required by the Company's bylaws or otherwise. However, the Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee and the Board in their discretion may direct the appointment of a different independent accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting will be required to ratify the selection of Ernst & Young LLP. Abstentions will be counted towards the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

THE BOARD RECOMMENDS A VOTE FOR PROPOSAL 4.

Section 16(a) of the Exchange Act requires the Company's directors and executive officers, and persons who own more than ten percent of a registered class of the Company's equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of Common Stock and other equity securities of the Company. Executive officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file.

To the Company's knowledge, based solely on a review of the copies of such reports furnished to the Company and written representations that no other reports were required during 2001, the Company's executive officers, directors and greater than ten percent beneficial owners complied with all Section 16(a) filing requirements applicable to these executive officers, directors and greater than ten percent beneficial owners, except that Dr. Nicole P. Onetto, former Senior Vice President, Medical Affairs, filed an amended Form 4 report covering the sale of 7,600 shares which was not included in the initial timely filing of the original Form 4 report.

Compensation Committee Interlocks and Insider Participation

The Company's Compensation Committee consists of Drs. Moore (Chairman) and Berg, Mr. Denny and Mrs. Wilson. None of the members of the Compensation Committee is currently or has been, at any time since the Company's formation, one of the Company's officers or employees.

Executive Compensation

Compensation of Directors

Each non-employee director of the Company receives an annual retainer of $25,000, a fee of $1,500 for each Board meeting attended and an additional $1,000 ($1,500 for Committee Chair) for each committee meeting attended. For the year ended December 31, 2001, the total compensation paid to current non-employee directors was $238,750. The members of the Board are also eligible for reimbursement for their expenses incurred in connection with attendance at Board meetings in accordance with Company policy.

Each non-employee director of the Company also receives stock option grants under the Directors' Option Plan. The Directors' Option Plan provides for non-discretionary grants of nonstatutory stock options to non-employee directors of the Company, on an automatic basis pursuant to a pre-approved schedule. Options granted under the Directors' Option Plan are at prices not less than fair value on the date of grant, become exercisable over a period of five years in equal quarterly installments at the rate of 5% per quarter and expire after ten years. Such vesting is conditioned upon continuous service as a non-employee director of or consultant to the Company. The exercise price of options granted must be paid in cash or shares of Common Stock of Gilead at the time the option is exercised.

Each non-employee director was granted as of January 2, 1996, or on such later date as he or she first became a non-employee director, an initial stock option grant to purchase 100,000 shares of Common Stock of Gilead. Thereafter, on each anniversary date of a non-employee director's initial grant, the non-employee director is automatically, without further action by the Company, the Board or stockholders of the Company, granted an annual stock option grant to purchase 15,000 shares of Common Stock of Gilead. A non-employee director who is also the Chairperson of the Board is granted an option to purchase an additional 80,000 shares of Common Stock of Gilead at the time of his or her initial grant or later election as Chairperson, and an additional 12,000 shares of Common Stock of Gilead at the time of his or her annual grant. Each non-employee director who serves on a standing committee of the Board is automatically granted an option to purchase an additional 4,000 shares of Common Stock of Gilead at the time of his or her initial grant, and an additional 3,000 shares of Common Stock of Gilead at the time of his or her annual grant, for each such committee. Each non-employee director who serves on a standing committee and who is also the Chairperson of that committee is automatically granted an option to purchase 8,000 shares at the time of the initial grant or later election as Chairperson and an additional 6,000 shares of Common Stock of Gilead at the time of his or her annual grant. No other options may be granted under the Directors' Option Plan.

During 2001, the Company granted options covering 472,000 shares to its current non-employee directors, at exercise prices ranging from $14.7969 to $34.3250 per share. Each option granted had an exercise price equal to the fair value of the Company's Common Stock on the date of grant.

As of February 28, 2002, options to purchase a total of 1,485,000 shares of Common Stock of Gilead were outstanding under the Directors' Option Plan.

Crispin G.S. Eley	60,000	.96	%	$	14.7969	1/17/11	$	558,148	$	1,414,346

(1): The terms of such options, which include both incentive and nonstatutory stock options, are consistent with those of options granted to other employees under the Restated 1991 Plan. The

options vest at the rate of 20% after one year and 5% per quarter thereafter during the optionee's employment. Subject to certain exceptions, the maximum term of options granted under the Restated 1991 Plan is ten years. All share amounts and per share references have been restated to reflect the stock split effected in the form of a stock dividend completed on March 8, 2002.

(2): Based on options to purchase 6,236,860 shares of Common Stock granted to employees, including executive officers, for the year ended December 31, 2001.
(3): The potential realizable value is based on the term of the option at the date of the grant. It is calculated by assuming that the stock price on the date of grant appreciates at the indicated annual rate, compounded annually for the entire term, and that the option is exercised and sold on the last day of the option term for the appreciated stock price. Actual gains, if any, are dependent on the actual future performance of Gilead's Common Stock and the timing of exercise and sale transactions by the holder. These numbers are based on the SEC requirements and do not reflect the Company's projection or estimate of future stock price growth.
(4): On December 31, 2001 Dr. Onetto left the Company in connection with the sale of Gilead's oncology assets to OSI Pharmaceuticals, Inc.

Compensation Committee Report(1)

During the fiscal year ended December 31, 2001, the Compensation Committee of the Board (the "Compensation Committee") was comprised of Drs. Moore (Chairman) and Berg and Mr. Denny from January 1, 2001 through October 25, 2001 and since October 26, 2001 has been and is currently comprised of Drs. Moore (Chairman) and Berg, Mr. Denny and Mrs. Wilson. None of the Compensation Committee members is an officer or an employee of the Company. The Compensation Committee is responsible for making recommendations and taking actions concerning salaries and incentive compensation of officers and employees of the Company, including the award of stock options under the Company's stock option plans. In particular, the Compensation Committee evaluates the performance of management and determines the compensation of the Chief Executive Officer and other Named Executive Officers on an annual basis. The Chief Executive Officer is not present during the discussion of his compensation.

(1): This Report is not "soliciting material," is not deemed "filed" with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

The Company's executive compensation philosophy is to attract and retain executive officers capable of leading the Company to fulfillment of its business objectives by offering competitive compensation opportunities that reward individual contributions as well as corporate performance. In addition, long-term equity compensation is awarded to align the interests of management and stockholders. The Company provides executive officers (and key employees) of the Company with a substantial economic interest in the long-term appreciation of the Company's Common Stock through the grant of stock options, subject to vesting restrictions.

The Compensation Committee met in January 2002 to determine salary and incentive compensation for the Company's Chief Executive Officer and other Named Executive Officers. Compensation for the Chief Executive Officer and each of the Company's other Named Executive Officers generally consists of three elements: cash salary, a performance-based cash bonus and stock option grants with exercise prices set at fair value at the time of grant. Base salaries and cash bonuses are determined annually, based in part on the achievement of corporate performance goals and objectives set by the Board and the Company's Chief Executive Officer. Under this performance criteria, the Chief Executive Officer's compensation is based entirely on the Company's success in meeting these established goals and objectives, while compensation for each Named Executive Officer is weighted between the Company's success (75%) and the performance of the respective functional group under that Named Executive Officer's responsibility (25%) in meeting those same goals and objectives. The Compensation Committee makes no other distinctions between the basis for the Chief Executive Officer's compensation and those factors and criteria upon which the other Named Executive Officer's compensation is based. Long-term equity incentives are granted to all Named Executive Officers from time to time on a discretionary basis. In determining compensation for all Named Executive Officers, the Compensation Committee also takes into consideration the financial condition and prospects for the Company as well as any promotions or changes in responsibilities that may have taken place during the fiscal year. Total compensation paid by the Company to its Chief Executive Officer and its other Named Executive Officers is designed to be competitive with compensation packages paid to the management of comparable companies in the biopharmaceutical industry. As in previous years, in making its compensation decisions, the Compensation Committee took into consideration executive compensation information from other biopharmaceutical companies, including industry surveys, publicly available information and reports from compensation consulting firms. The information reviewed by the Compensation Committee is not necessarily from the same group of companies that are included in the market indices in the graph included under "Performance Measurement Comparison" in this Proxy Statement.

Many traditional measures of corporate performance, such as earnings per share or sales growth, are less important in reviewing performance of executives in the biopharmaceutical industry, as compared to more established industries. Because of the Company's current stage of development, the Compensation Committee emphasizes other indications of performance, such as the progress of the Company's research and development programs and corporate development activities. These qualitative factors necessarily involve a subjective assessment by the Compensation Committee of corporate performance. Moreover, the Compensation Committee does not base its considerations on any single performance factor, nor does it specifically assign relative weight to factors, but rather considers a mix of factors and evaluates Company and individual performance against that mix.

In its January 2002 meeting, the Compensation Committee authorized increased compensation, including base salaries, performance-based cash bonuses and stock option grants for the Chief Executive Officer and the other Named Executive Officers based on the objective criteria discussed in this report. Specifically, the Compensation Committee concluded that the Company achieved or made progress towards the following stated performance goals and objectives established by the Company for the year 2001:

•: filings for marketing approval in both the United States and Europe for tenofovir disoproxil fumarate ("tenofovir DF") were completed by May 2001 and approved by the FDA and recommended for approval by the European Union Committee for Proprietary Medicinal Products in October 2001;
•: Viread™, a formulation of tenofovir DF, was successfully launched prior to its original target date;
•: manufacturing targets for development and commercial supplies of tenofovir DF were met as well as expectations for quantity and cost effectiveness of tenofovir DF's Active Pharmaceutical Ingredient (API) production;
•: the Company made significant progress in controlling expenses and meeting revenue targets;
•: the expanded access program for tenofovir DF was successfully designed and executed;
•: milestones for NX 211 and two pre-clinical oncology products were met;
•: milestones were achieved for adevofir dipivoxil for hepatitis B; and
•: the objective to introduce two new products into the Company's pipeline through licensing, acquisition, co-promotion or internal research programs was achieved with the commercialization agreement entered into with Cubist Pharmaceuticals, Inc. for European sales rights to Cidecin™ and the identification of GS 7340, a novel nucleotide analog reverse transcriptase inhibitor, through internal research.

In addition, the Compensation Committee considered the following additional accomplishments in the year 2001:

•: the Company's oncology programs and research and development organizational structure were evaluated;
•: the Company's oncology assets and related technology were sold to OSI Pharmaceuticals for a pretax gain of $157.8 million;
•: a potential protease inhibitor candidate was identified through internal research;
•: the Company successfully licensed its SELEX™ (Systemic Evolution of Ligands through EXponential Enrichment) patent rights to Archemix Corporation for $17.5 million;
•: the Company's interest in Proligo, L.L.C. was sold for $14.3 million; and

•: the Company launched its new branding and logo project.

The Compensation Committee believes that the continued commitment and leadership of the Company's executive officers through fiscal year 2001 were and continue to be important factors in the Company's achievements.

Compliance with Internal Revenue Code Section 162(m).

Section 162(m) of the Internal Revenue Code (the "Code") generally provides that publicly held companies may not deduct compensation paid to certain of its top executive officers to the extent that such compensation exceeds $1 million per officer in a calendar year. Compensation that is "performance-based compensation" within the meaning of the Code does not count toward the $1 million limit. The Compensation Committee has determined that ordinary income recognized by the Company's Named Executive Officers as a result of their exercise of stock options granted by the Compensation Committee under the Restated 1991 Plan having an exercise price at least equal to the fair market value of the Company's Common Stock on the date of grant, qualifies as performance- based compensation as defined under Section 162(m) of the Code. Except for compensation paid to the Chief Executive Officer, the Company expects that amounts of compensation paid to its Named Executive Officers will fall within the $1 million limit under Section 162(m) of the Code.

Audit Committee Report(1)

From January 1, 2001 through April 18, 2001, the Audit Committee of the Board (the "Audit Committee") consisted of Mr. Denny (Chairman) and Drs. Shultz and Moore. From April 19, 2001 through December 31, 2001, the Audit Committee consisted of Mr. Hull (Chairman) and Drs. Shultz and Moore. Mr. Denny, Chairman of the Board of Directors, during 2001, attended two of the four Audit Committee meetings in an ex-officio capacity. None of the Audit Committee members is an officer or an employee of the Company and all are "independent" directors and meet the financial literacy requirements under NASD rules.

(1): This Report is not "soliciting material," is not deemed "filed" with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

The Audit Committee oversees the Company's financial reporting process on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal control. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements included in the Annual Report on Form 10-K with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity and completeness of disclosures in the financial statements.

The Audit Committee reviewed with the independent auditors, who are responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States, their judgments as to the quality, not just the acceptability, of the Company's accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. The Audit Committee has discussed with the independent auditors the matters required to be discussed by Statement of Auditing Standards 61 as well as the auditors' independence from management and the Company, including the matters in the written disclosures received by the Audit Committee in accordance with the requirements of the Independence Standards Board Standard No. 1. The Audit Committee has also considered the compatibility of non-audit services with the auditors' independence.

The Audit Committee discussed with the Company's independent auditors the overall scope and plans for their audit. The Audit Committee meets with the independent auditors, with and without management present, to discuss the results of their audit and quarterly reviews, their evaluations of the Company's internal controls and the overall quality of the Company's financial reporting. The Audit Committee held four regular meetings, one special meeting and acted by unanimous written consent once during 2001.

In reliance on the reviews and discussion referred to above, the Audit Committee recommended to the Board (and the Board approved) that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2001 for filing with the SEC. The Audit Committee and the Board have also recommended, subject to stockholder ratification, the selection of the Company's independent auditors.

Performance Measurement Comparison(1)

The following graph compares total stockholder returns of Gilead since its initial public offering of Common Stock on January 22, 1992 to two indices: the Nasdaq CRSP Total Return Index for The Nasdaq Stock Market (U.S. companies), labeled Nasdaq-US, and the Nasdaq Pharmaceutical Index, labeled Nasdaq-Pharmaceutical. The total return for Gilead's Common Stock and for each index assumes the reinvestment of dividends, although cash dividends have never been declared on Gilead's Common Stock, and is based on the returns of the component companies weighted according to their capitalizations as of the end of each monthly period. The Nasdaq-US tracks the aggregate price performance of equity securities of U.S. companies traded on The Nasdaq Stock Market. The Nasdaq-Pharmaceutical tracks the aggregate price performance of equity securities of pharmaceutical companies traded on The Nasdaq Stock Market. Gilead's Common Stock is traded on The Nasdaq Stock Market and is a component of both the Nasdaq-US and the Nasdaq-Pharmaceutical.

(a) The Plan initially was adopted on November 15, 1991 and amended through October 17, 1995 (the "Initial Plan"). The Initial Plan was amended and restated in its entirety effective as of January 22, 1998 and amended through March 30, 1999. The Plan was amended and restated in its entirety, effective as of April 5, 2000 and further amended effective January 18, 2001.

The terms of the Plan (excluding the previously amended provision relating to the exercise price of Nonstatutory Stock Options) shall apply to all options granted pursuant to the Initial Plan.

(b) The purpose of the Plan is to provide a means by which selected Employees and Directors of, and Consultants to, the Company and its Affiliates may be given an opportunity to purchase stock of the Company.

(d) The Company intends that the Options issued under the Plan shall, in the discretion of the Board or any Committee to which responsibility for administration of the Plan has been delegated pursuant to subsection 3(c), be either Incentive Stock Options or Nonstatutory Stock Options. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and in such form as issued pursuant to Section 6, and a separate certificate or certificates will be issued for shares purchased on exercise of each type of Option.

B-3

(ii) To construe and interpret the Plan and Options granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Option Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective.

(b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise.

5. Eligibility.

(a) Incentive Stock Options may be granted only to Employees. Nonstatutory Stock Options may be granted to Employees, Directors and Consultants.

6. Option Provisions.

Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions:

(a) Term. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted.

(b) Price.

(i) Exercise Price. The exercise price of each Incentive Stock Option and each Nonstatutory Stock Option shall be not less than one hundred percent (100%) of the fair market value of the stock subject to the Option on the date the Option is granted.

(ii) No Authority to Reprice. Without the consent of the stockholders of the Company, the Board shall have no authority to effect (a) the repricing of any outstanding Options under the Plan and/or (b) the cancellation of any outstanding Options under the Plan and the grant in substitution therefor of new Options under the Plan covering the same or different numbers of shares of Common Stock.

(c) Consideration. The purchase price of stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (i) in cash at the time the Option is exercised, or (ii) at the discretion of the Board or the Committee, at the time of the grant of the Option, (A) by delivery to the Company of other common stock of the Company, (B) according to a deferred payment arrangement, except that payment of the common stock's "par value" (as defined in the Delaware General Corporation Law) shall not be made by deferred payment or other arrangement (which may include, without limiting the generality of the foregoing, the use of other common stock of the Company) with the person to whom the Option is granted or to whom the Option is transferred pursuant to subsection 6(d), or (C) in any other form of legal consideration that may be acceptable to the Board.

In the case of any deferred payment arrangement, interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement.

(d) Transferability. An Incentive Stock Option shall not be transferable except by will or by the laws of descent and distribution, and shall be exercisable during the lifetime of the person to whom the Option is granted only by such person. A Nonstatutory Stock Option but not an Incentive Stock Option, may be transferred to the extent provided in the Option Agreement; provided that if the Option Agreement does not expressly permit the transfer of a Nonstatutory Stock Option, the Nonstatutory Stock Option shall not be transferable except by will, by the laws of descent and distribution and shall be exercisable during the lifetime of the person to whom the Option is granted only by such person. The person to whom the Option is granted may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Option.

(e) Vesting. The total number of shares of stock subject to an Option may, but need not, be allotted in periodic installments (which may, but need not, be equal). The Option Agreement may provide that from time to time during each of such installment periods, the Option may become exercisable ("vest") with respect to some or all of the shares allotted to that period, and may be exercised with respect to some or all of the shares allotted to such period and/or any prior period as to which the Option became vested but was not fully exercised. During the remainder of the term of the

B-5

Option (if its term extends beyond the end of the installment periods), the option may be exercised from time to time with respect to any shares then remaining subject to he Option. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The provisions of this subsection 6(e) are subject to any Option provisions governing the minimum number of shares as to which an Option may be exercised.

(f) Securities Law Compliance. The Company may require any Optionee, or any person to whom an Option is transferred under subsection 6(d), as a condition of exercising any such Option, (1) to give written assurances satisfactory to the Company as to the Optionee's knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters, and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Option; and (2) to give written assurances satisfactory to the Company stating that such person is acquiring the stock subject to the Option for such person's own account and not with any present intention of selling or otherwise distributing the stock. These requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares upon the exercise of the Option has been registered under a then currently effective registration statement under the Securities Act of 1933, as amended (the "Securities Act"), or (ii) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may require the Optionee to provide such other representations, written assurances, or information which the Company shall determine is necessary, desirable or appropriate to comply with applicable securities and other laws as a condition of granting an Option to such Optionee or permitting the Optionee to exercise such Option. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock.

(g) Termination of Employment or Consulting Relationship. In the event an Optionee's Continuous Service terminates (other than upon the Optionee's death or Disability), the Optionee may exercise his or her Option, but only within such period of time as is determined by the Board, and only to the extent that the Optionee was entitled to exercise it at the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the case of an Incentive Stock Option, the Board shall determine such period of time (in no event to exceed ninety (90) days from the date of termination) when the Option is granted. If, at the date of termination, the Optionee is not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate, and the shares covered by such Option shall revert to the Plan.

(h) Disability of Optionee. In the event an Optionee's Continuous Service terminates as a result of the Optionee's Disability, the Optionee may exercise his or her Option, but only within twelve (12) months from the date of such termination (or such shorter period specified in the Option Agreement), and only to the extent that the Optionee was entitled to exercise it at the date of such termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). If, at the date of termination, the Optionee is not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to the Plan.

B-6

(i) Death of Optionee. In the event of the death of an Optionee, the Option may be exercised, at any time within twelve (12) months following the date of death (or such shorter period specified in the Option Agreement) (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement), by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent the Optionee was entitled to exercise the Option at the date of death. If, at the time of death, the Optionee was not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to the Plan. If, after death, the Optionee's estate or a person who acquired the right to exercise the Option by bequest or inheritance does not exercise the Option within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to the Plan.

(j) Early Exercise. The Option may, but need not, include a provision whereby the Optionee may elect at any time while an Employee or Consultant to exercise the Option as to any part or all of the shares subject to the Option prior to the full vesting of the Option. Any unvested shares so purchased may be subject to a repurchase right in favor of the Company or to any other restriction the Board determines to be appropriate.

(k) Withholding. To the extent provided by the terms of an Option Agreement, the Optionee may satisfy any federal, state or local tax withholding obligation relating to the exercise of such Option by any of the following means or by a combination of such means: (1) tendering a cash payment; (2) authorizing the Company to withhold shares from the shares of the common stock otherwise issuable to the Optionee as a result of the exercise of the Option; or (3) delivering to the Company owned and unencumbered shares of the common stock of the Company.

7. Covenants Of The Company.

(a) During the terms of the Options, the Company shall keep available at all times the number of shares of stock required to satisfy such Options.

(b) The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the Options; provided, however, that this undertaking shall not require the Company to register under the Securities Act either the Plan, any Option or any stock issued or issuable pursuant to any such Option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Options unless and until such authority is obtained.

8. Use Of Proceeds From Stock.

Proceeds from the sale of stock pursuant to Options shall constitute general funds of the Company.

9. Miscellaneous.

(a) The Board shall have the power to accelerate the time at which an Option may first be exercised or the time during which an Option or any part thereof will vest pursuant to subsection 6(e), notwithstanding the provisions in the Option stating the time at which it may first be exercised or the time during which it will vest.

(b) Neither an Optionee nor any person to whom an Option is transferred under subsection 6(d) shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such Option unless and until such person has satisfied all requirements for exercise of the Option pursuant to its terms.

(c) Nothing in the Plan or any instrument executed or Option granted pursuant thereto shall confer upon any Employee, Consultant or Optionee any right to continue in the employ of the

B-7

Company or any Affiliate (or to continue acting as a Consultant) or shall affect the right of the Company or any Affiliate to terminate the employment or relationship as a Consultant of any Employee, Consultant or Optionee with or without cause.

(d) To the extent that the aggregate Fair Market Value (determined at the time of grant) of stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year under all plans of the Company and its Affiliates exceeds one hundred thousand dollars ($100,000), the Options or portions thereof which exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options.

10. Adjustments Upon Changes In Stock.

(a) If any change is made in the stock subject to the Plan, or subject to any Option (through merger, consolidation, reorganization, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or otherwise), the Plan will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan pursuant to subsection 4(a) and the maximum number of shares subject to award to any person during any calendar year period pursuant to subsection 5(d), and the outstanding Options will be appropriately adjusted in the class(es) and number of shares and price per share of stock subject to such outstanding Options.

(b) In the event of: (1) a dissolution or liquidation of the Company; (2) a merger or consolidation in which the Company is not the surviving corporation; (3) a reverse merger in which the Company is the surviving corporation but the shares of the Company's common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (4) any other capital reorganization in which more than fifty percent (50%) of the shares of the Company entitled to vote are exchanged, then, at the sole discretion of the Board and to the extent permitted by applicable law: (i) any surviving corporation shall assume any Options outstanding under the Plan or shall substitute similar Options for those outstanding under the Plan, (ii) the time during which such Options may be exercised shall be accelerated and the Options terminated if not exercised prior to such event, or (iii) such Options shall continue in full force and effect.

(c) Notwithstanding any other provisions of this Plan to the contrary, if an event occurs as specified in subsection 10(b) (a "Change in Control") and if within one (1) month before or thirteen (13) months after the date of such Change in Control the Continuous Service of an Optionee terminates due to an involuntary termination (not including death or Disability) without Cause (as such term is defined below) or a voluntary termination by the Optionee due to a Constructive Termination (as such term is defined below), then the vesting and exercisability of all Options held by such Optionee shall be accelerated, or any reacquisition or repurchase rights held by the Company with respect to an option shall lapse, as follows. With respect to those Options held by an Optionee at the time of such termination, one hundred percent (100%) of the unvested shares covered by such Options shall vest and become exercisable (or reacquisition or repurchase rights held by the Company shall lapse with respect to one hundred percent (100%) of the shares still subject to such rights, as appropriate) as of the date of such termination. Notwithstanding the foregoing, however, if such potential acceleration of the vesting and exercisability of Options (or lapse of reacquisition or repurchase rights held by the Company with respect to Options) would cause a contemplated Change in Control transaction that would otherwise be eligible to be accounted for as a "pooling-of-interests" transaction to become ineligible for such accounting treatment under generally accepted accounting principles as determined by the Company's independent public accountants (the "Accountants") prior to the Change of Control, such acceleration shall not occur.

For the purposes of this subsection 10(c) only, "Cause" means (i) conviction of, a guilty plea with respect to, or a plea of nolo contendere to a charge that an Optionee has committed a felony under the

laws of the United States or of any state or a crime involving moral turpitude, including, but not limited to, fraud, theft, embezzlement or any crime that results in or is intended to result in personal enrichment at the expense of the Company or an Affiliate; (ii) material breach of any agreement entered into between the Optionee and the Company or an Affiliate that impairs the Company's or the Affiliate's interest therein; (iii) willful misconduct, significant failure of the Optionee to perform the Optionee's duties, or gross neglect by the Optionee of the Optionee's duties; or (iv) engagement in any activity that constitutes a material conflict of interest with the Company or any Affiliate.

For purposes of this subsection 10(c) only, "Constructive Termination" means the occurrence of any of the following events or conditions: (i) (A) a change in the Optionee's status, title, position or responsibilities (including reporting responsibilities) which represents an adverse change from the Optionee's status, title, position or responsibilities as in effect at any time within ninety (90) days preceding the date of a Change in Control or at any time thereafter; (B) the assignment to the Optionee of any duties or responsibilities which are inconsistent with the Optionee's status, title, position or responsibilities as in effect at any time within ninety (90) days preceding the date of a Change in Control or at any time thereafter; or (C) any removal of the Optionee from or failure to reappoint or reelect the Optionee to any of such offices or positions, except in connection with the termination of the Optionee's Continuous Service for Cause, as a result of the Optionee's Disability or death or by the Optionee other than as a result of Constructive Termination; (ii) a reduction in the Optionee's annual base compensation or any failure to pay the Optionee any compensation or benefits to which the Optionee is entitled within five (5) days of the date due; (iii) the Company's requiring the Optionee to relocate to any place outside a fifty (50) mile radius of the Optionee's current work site, except for reasonably required travel on the business of the Company or its Affiliates which is not materially greater than such travel requirements prior to the Change in Control; (iv) the failure by the Company to (A) continue in effect (without reduction in benefit level and/or reward opportunities) any material compensation or employee benefit plan in which the Optionee was participating at any time within ninety (90) days preceding the date of a Change in Control or at any time thereafter, unless such plan is replaced with a plan that provides substantially equivalent compensation or benefits to the Optionee, or (B) provide the Optionee with compensation and benefits, in the aggregate, at least equal (in terms of benefit levels and/or reward opportunities) to those provided for under each other employee benefit plan, program and practice in which the Optionee was participating at any time within ninety (90) days preceding the date of a Change in Control or at any time thereafter; (v) any material breach by the Company of any provision of an agreement between the Company and the Optionee, whether pursuant to this Plan or otherwise, other than a breach which is cured by the Company within fifteen (15) days following notice by the Optionee of such breach; or (vi) the failure of the Company to obtain an agreement, satisfactory to the Optionee, from any successors and assigns to assume and agree to perform the obligations created under this Plan.

(d) In the event that the acceleration of the vesting and exercisability of the Options or lapse of reacquisition or repurchase rights held by the Company with respect to Options provided for in subsection 10(c) and benefits otherwise payable to an Optionee (i) constitute "parachute payments" within the meaning of Section 280G (as it may be amended or replaced) of the Code, and (ii) but for this subsection 10(d) would be subject to the excise tax imposed by Section 4999 (as it may be amended or replaced) of the Code (the "Excise Tax"), then such optionee's benefits hereunder shall be delivered to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax; provided, however, that the benefits hereunder shall be reduced only to the extent necessary after all cash amounts otherwise payable to such optionee and which constitute "parachute payments" have been returned. Unless the Company and such optionee otherwise agree in writing, any determination required under this subsection 10(d) shall be made in writing in good faith by the Accountants. For purposes of making the calculations required by this subsection 10(d), the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of the Code. The Company and such optionees

(iii) Modify the requirements as to eligibility for participation in the Plan (to the extent such modification requires stockholder approval in order for the Plan to satisfy the requirements of Section 422 of the Code); or

(iv) Modify the Plan in any other way if such modification requires stockholder approval in order for the Plan to satisfy the requirements of Section 422 of the Code or to comply with the requirements of Rule 16b-3 or any Nasdaq or securities exchange listing requirements.

(b) The Board may in its sole discretion submit any other amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations promulgated thereunder regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to certain executive officers.

(c) It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide optionees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options and/or to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith.

(d) Rights and obligations under any Option granted before amendment of the Plan shall not be altered or impaired by any amendment of the Plan unless (i) the Company requests the consent of the person to whom the Option was granted and (ii) such person consents in writing.

1. Purpose.

(a) The purpose of the 1995 Non-Employee Directors' Stock Option Plan (the "Plan") is to provide a means by which each director of Gilead Sciences, Inc. (the "Company") who is not otherwise an employee of the Company or of any Affiliate of the Company (each such person being hereafter referred to as a "Non-Employee Director") will be given an opportunity to purchase stock of the Company.

(b) The word "Affiliate" as used in the Plan means any parent corporation or subsidiary corporation of the Company as those terms are defined in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended from time to time (the "Code").

(c) The Company, by means of the Plan, seeks to retain the services of persons now serving as Non-Employee Directors of the Company, to secure and retain the services of persons capable of serving in such capacity, and to provide incentives for such persons to exert maximum efforts for the success of the Company.

(a) The Plan shall be administered by the Board of Directors of the Company (the "Board") unless and until the Board delegates administration to a committee, as provided in subparagraph 2(b).

(b) The Board may delegate administration of the Plan to a committee composed of not fewer than two (2) members of the Board (the "Committee"). If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan.

3. Shares Subject To The Plan.

(a) Subject to the provisions of paragraph 10 relating to adjustments upon changes in stock, the stock that may be sold pursuant to options granted under the Plan shall not exceed in the aggregate two million eight hundred thousand (2,800,000) shares of the Company's common stock. If any option granted under the Plan shall for any reason expire or otherwise terminate without having been exercised in full, the stock not purchased under such option shall again become available for the Plan.

(b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise.

C-1

4. Eligibility.

Options shall be granted only to Non-Employee Directors of the Company.

5. Non-Discretionary Grants.

(a) On January 2, 1996, each person who is then a Non-Employee Director automatically shall be granted an option to purchase one hundred thousand (100,000) shares of common stock of the Company on the terms and conditions set forth herein.

(b) Each person who is, after January 2, 1996, elected for the first time to be a Non-Employee Director automatically shall, upon the date of initial election to be a Non-Employee Director by the Board or stockholders of the Company, be granted an option to purchase one hundred thousand (100,000) shares of common stock of the Company on the terms and conditions set forth herein.

(c) On the one-year anniversary date of each Non-Employee Director's initial grant under subparagraph 5(a) or 5(b) above, and on each one-year anniversary date thereafter, each person who is then a Non-Employee Director automatically shall be granted an option to purchase fifteen thousand (15,000) shares of common stock of the Company on the terms and conditions set forth herein.

(d) In addition to the option grants described above, the Chairperson of the Board, if he or she is a Non-Employee Director, or a Non-Employee Director designated by the Board as a "lead director" in circumstances where there is no Chairperson or the Chairperson is an employee of the Company, automatically shall be granted options to purchase: (i) eighty thousand (80,000) shares of common stock of the Company, at the time of his or her initial grant under subparagraph 5(a) or 5(b) above or upon later election as Chairperson or designation as lead director; and (ii) twelve thousand (12,000) shares of common stock of the Company at the time of each annual grant under subparagraph 5(c) above, all such grants to be on the terms and conditions set forth herein.

(e) In addition to the option grants described above, each Non-Employee Director who serves on a standing committee of the Board automatically shall be granted options to purchase: (i) four thousand (4,000) shares of common stock of the Company, at the time of his or her initial grant under subparagraph 5(a) or 5(b) above or upon later election to each such committee, plus an additional eight thousand (8,000) shares of common stock of the Company at the same time for the Chairperson of each such committee; and (ii) three thousand (3,000) shares of common stock of the Company at the time of each annual grant under subparagraph 5(c) above, plus an additional six thousand (6,000) shares of common stock of the Company for the Chairperson of each such committee, at the time of each annual grant, all such grants to be on the terms and conditions set forth herein.

6. Option Provisions.

Each option granted under the Plan shall be subject to the following terms and conditions:

(a) The term of each option commences on the date it is granted and, unless sooner terminated as set forth herein, expires on the date ("Expiration Date") ten (10) years from the date of grant. If the optionee's service as a Non-Employee Director or employee of or consultant to the Company or any Affiliate terminates for any reason or for no reason, the option shall terminate on the earlier of the Expiration Date or the date three (3) months following the date of termination of all such service; provided, however, that if such termination of service is due to the optionee's death or permanent and total disability (within the meaning of Section 422(c)(6) of the Code), the option shall terminate on the earlier of the Expiration Date or one (1) year following the date of the optionee's death or permanent and total disability. In any and all circumstances, an option may be exercised following termination of the optionee's service as a Non-Employee Director or employee of or consultant to the Company or any Affiliate only as to that number of shares as to which it was exercisable on the date of termination of all such service under the provisions of subparagraph 6(e).

C-2

(b) The exercise price of each option shall be one hundred percent (100%) of the fair market value of the stock subject to such option on the date such option is granted.

(c) Payment of the exercise price of each option is due in full in cash upon any exercise when the number of shares being purchased upon such exercise is less than 4,000 shares; but when the number of shares being purchased upon an exercise is 4,000 or more shares, the optionee may elect to make payment of the exercise price under one of the following alternatives:

(i) Payment of the exercise price in cash at the time of exercise; or

(ii) Provided that at the time of the exercise the Company's common stock is publicly traded and quoted regularly in the Wall Street Journal, payment by delivery of shares of common stock of the Company already owned by the optionee, held for the period required to avoid a charge to the Company's reported earnings, and owned free and clear of any liens, claims, encumbrances or security interests, which common stock shall be valued at its fair market value on the date preceding the date of exercise; or

(iii) Payment by a combination of the methods of payment specified in subparagraphs 6(c)(i) and 6(c)(ii) above.

Notwithstanding the foregoing, this option may be exercised pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board which results in the receipt of cash (or check) by the Company prior to the issuance of shares of the Company's common stock.

(d) An option shall not be transferable except by will or by the laws of descent and distribution, or pursuant to a qualified domestic relations order satisfying the requirements of Rule 16b-3 under the Securities Exchange Act of 1934, as amended ("Rule 16b-3") and shall be exercisable during the lifetime of the person to whom the option is granted only by such person (or by his guardian or legal representative) or transferee pursuant to such an order. Notwithstanding the foregoing, the optionee may, by delivering written notice to the Company in a form satisfactory to the Company, designate a third party who, in the event of the death of the optionee, shall thereafter be entitled to exercise the option.

(e) The option shall become exercisable in installments over a period of five (5) years from the date of grant at the rate of five percent (5%) in equal quarterly installments commencing on the date three (3) months after the date of grant of the option, provided that the optionee has, during the entire period prior to such vesting date, continuously served as a Non-Employee Director or employee of or consultant to the Company or any Affiliate of the Company, whereupon such option shall become fully exercisable in accordance with its terms with respect to that portion of the shares represented by that installment.

(f) The Company may require any optionee, or any person to whom an option is transferred under subparagraph 6(d), as a condition of exercising any such option: (i) to give written assurances satisfactory to the Company as to the optionee's knowledge and experience in financial and business matters; and (ii) to give written assurances satisfactory to the Company stating that such person is acquiring the stock subject to the option for such person's own account and not with any present intention of selling or otherwise distributing the stock. These requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares upon the exercise of the option has been registered under a then-currently-effective registration statement under the Securities Act of 1933, as amended (the "Securities Act"), or (ii), as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then-applicable securities laws.

(g) Notwithstanding anything to the contrary contained herein, an option may not be exercised unless the shares issuable upon exercise of such option are then registered under the Securities Act or,

C-3

if such shares are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act.

7. Covenants Of The Company.

(a) During the terms of the options granted under the Plan, the Company shall keep available at all times the number of shares of stock required to satisfy such options.

(b) The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the options granted under the Plan; provided, however, that this undertaking shall not require the Company to register under the Securities Act either the Plan, any option granted under the Plan, or any stock issued or issuable pursuant to any such option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such options.

8. Use Of Proceeds From Stock.

Proceeds from the sale of stock pursuant to options granted under the Plan shall constitute general funds of the Company.

9. Miscellaneous.

(a) Neither an optionee nor any person to whom an option is transferred under subparagraph 6(d) shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such option unless and until such person has satisfied all requirements for exercise of the option pursuant to its terms.

(b) Throughout the term of any option granted pursuant to the Plan, the Company shall make available to the holder of such option, not later than one hundred twenty (120) days after the close of each of the Company's fiscal years during the option term, upon request, such financial and other information regarding the Company as comprises the annual report to the stockholders of the Company provided for in the Bylaws of the Company and such other information regarding the Company as the holder of such option may reasonably request.

(c) Nothing in the Plan or in any instrument executed pursuant thereto shall confer upon any Non-Employee Director any right to continue in the service of the Company or any Affiliate or shall affect any right of the Company, its Board or stockholders or any Affiliate to terminate the service of any Non-Employee Director with or without cause.

(d) No Non-Employee Director, individually or as a member of a group, and no beneficiary or other person claiming under or through him, shall have any right, title or interest in or to any option reserved for the purposes of the Plan except as to such shares of common stock, if any, as shall have been reserved for him pursuant to an option granted to him.

(e) In connection with each option made pursuant to the Plan, it shall be a condition precedent to the Company's obligation to issue or transfer shares to a Non-Employee Director, or to evidence the removal of any restrictions on transfer, that such Non-Employee Director make arrangements satisfactory to the Company to insure that the amount of any federal or other withholding tax required to be withheld with respect to such sale or transfer, or such removal or lapse, is made available to the Company for timely payment of such tax.

C-4

(f) As used in this Plan, "fair market value" means, as of any date, the value of the common stock of the Company determined as follows:

(i) If the common stock is listed on any established stock exchange or a national market system, including without limitation the National Market System of the National Association of Securities Dealers, Inc. Automated Quotation ("Nasdaq") System, the Fair Market Value of a share of common stock shall be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on such system or exchange (or the exchange with the greatest volume of trading in common stock) on the last market trading day prior to the day of determination, as reported in the Wall Street Journal or such other source as the Board deems reliable;

(ii) If the common stock is quoted on the Nasdaq System (but not on the National Market System thereof) or is regularly quoted by a recognized securities dealer but selling prices are not reported, the Fair Market Value of a share of common stock shall be the mean between the bid and asked prices for the common stock on the last market trading day prior to the day of determination, as reported in the Wall Street Journal or such other source as the Board deems reliable;

(iii) In the absence of an established market for the common stock, the Fair Market Value shall be determined in good faith by the Board.

10. Adjustments Upon Changes In Stock.

(a) If any change is made in the stock subject to the Plan, or subject to any option granted under the Plan (through merger, consolidation, reorganization, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or otherwise), the Plan and outstanding options will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan and the class(es) and number of shares and price per share of stock subject to outstanding options.

(b) In the event of: (1) a merger or consolidation in which the Company is not the surviving corporation; (2) a reverse merger in which the Company is the surviving corporation but the shares of the Company's common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (3) any other capital reorganization in which more than fifty percent (50%) of the shares of the Company entitled to vote are exchanged, the time during which options outstanding under the Plan may be exercised shall be accelerated and the options terminated if not exercised prior to such event.

11. Amendment Of The Plan.

(a) The Board at any time, and from time to time, may amend the Plan, provided, however, that the Board shall not amend the plan more than once every six (6) months, with respect to the provisions of the Plan which relate to the amount, price and timing of grants, other than to comport with changes in the Code, the Employee Retirement Income Security Act, or the rules thereunder. Except as provided in paragraph 10 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the stockholders of the Company within twelve (12) months before or after the adoption of the amendment, where the amendment will:

(i) Increase the number of shares which may be issued under the Plan;

(ii) Modify the requirements as to eligibility for participation in the Plan (to the extent such modification requires stockholder approval in order for the Plan to comply with the requirements of Rule 16b-3); or

C-5

(iii) Modify the Plan in any other way if such modification requires stockholder approval in order for the Plan to comply with the requirements of Rule 16b-3 or Section 162(m) of the Internal Revenue Code.

12. Termination Or Suspension Of The Plan.

(a) The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on November 26, 2005. No options may be granted under the Plan while the Plan is suspended or after it is terminated.

(b) Rights and obligations under any option granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except with the consent of the person to whom the option was granted.

(c) The Plan shall terminate upon the occurrence of any of the events described in Section 10(b) above.

13. Effective Date Of Plan; Conditions Of Exercise.

(a) The Plan shall become effective upon adoption by the Board of Directors, subject to the condition subsequent that the Plan is approved by the stockholders of the Company.
