Exhibit 10.2

YAHOO! INC.
1995 STOCK PLAN
(MAY 1999 AMENDMENT)

    1.  Purposes of the Plan.  The purposes of this 1995 Stock Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to Employees and Consultants of the Company and its Subsidiaries and to promote the success of the Company's business. Options granted under the Plan may be incentive stock options (as defined under Section 422 of the Code) or nonstatutory stock options, as determined by the Administrator at the time of grant of an option and subject to the applicable provisions of Section 422 of the Code, as amended, and the regulations promulgated thereunder. Stock purchase rights may also be granted under the Plan.

    2.  Definitions.  As used herein, the following definitions shall apply:



    3.  Stock Subject to the Plan.  Subject to the provisions of Section 13 of the Plan, the maximum aggregate number of Shares that may be optioned and sold under the Plan is 126,000,000 shares of Common Stock. The Shares may be authorized, but unissued, or reacquired Common Stock. If an Option should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares that were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan. In addition, any Shares of Common Stock which are retained by the Company upon exercise of an Option or Stock Purchase Right in order to satisfy the exercise or purchase price for such Option or Stock Purchase Right or any withholding taxes due with respect to such exercise shall be treated as not issued and shall continue to be available under the Plan.

    4.  Administration of the Plan.  


    5.  Eligibility.  

    6.  Term of Plan.  The Plan shall become effective upon the earlier to occur of its adoption by the Board of Directors or its approval by the shareholders of the Company as described in Section 20 of the


Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 16 of the Plan.

    7.  Term of Option.  The term of each Option shall be the term stated in the Option Agreement; provided, however, that the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and provided further that, in the case of an Incentive Stock Option granted to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the written option agreement.

    8.  Limitation on Grants to Employees.  Subject to adjustment as provided in this Plan, the maximum number of Shares which may be subject to Options granted to any one Employee under this Plan for any fiscal year of the Company shall be 1,500,000.

    9.  Option Exercise Price and Consideration.  


    10.  Exercise of Option.  

    An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the Option is exercised. Full payment may, as authorized by the Board, consist of any consideration and method of payment allowable under Section 9(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, not withstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate promptly upon exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 13 of the Plan.

    Exercise of an Option in any manner shall result in a decrease in the number of Shares that thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

    (b)  Termination of Employment or Consulting Relationship.  Subject to Section 10(c), in the event of termination of an Optionee's Continuous Status as an Employee or Consultant with the Company, such Optionee may, but only within three (3) months (or such other period of time not less than thirty (30) days and not more than twelve (12) months as is determined by the Administrator, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option and not exceeding three (3) months) after the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise his or her Option to the extent that the Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of such termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. No termination shall be deemed to occur and this Section 10(b) shall not apply if (I) the Optionee is a Consultant who becomes an Employee; or (ii) the Optionee is an Employee who becomes a Consultant.

    (c)  Disability of Optionee.  Notwithstanding Section 10(b) above, in the event of termination of an Optionee's Continuous Status as an Employee or Consultant as a result of his or her total and permanent disability (within the meaning of Section 22(e)(3) of the Code), Optionee may, but only within twelve (12) months from the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise the Option to the extent otherwise entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate.

    (d)  Death of Optionee.  In the event of the death of an Optionee during the period of Continuous Status as an Employee or Consultant, or within thirty (30) days following the termination of the Optionee's Continuous Status as an Employee or Consultant, the Option may be exercised, at any time within twelve (12) months following the date of death (but in no event later than the expiration date 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 or, if earlier, the date of termination of the Continuous Status as an Employee or Consultant. To the extent that Optionee was not entitled to exercise the Option at the date of death or termination, as the case may be, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate.



    (e)  Extension of Exercise Period.  Notwithstanding the limitations set forth in Sections 10(b), (c) and (d) above, the Administrator has full power and authority to extend the period of time for which any Option granted under the Plan is to remain exercisable following termination of an Optionee's Continuous Status as an Employee or Consultant from the limited period set forth in the written option agreement to such greater period of time as the Administrator shall deem appropriate; provided, however, that in no event shall such Option be exercisable after the specified expiration date of the Option term.

    (f)  Rule 16b-3.  Options granted to Reporting Persons shall comply with Rule 16b-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption for Plan transactions.

    (g)  Buyout Provisions.  The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

    11.  Stock Purchase Rights.  

    (a)  Rights to Purchase.  Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid (which price shall not be less than 85% of the Fair Market Value of the Shares as of the date of the offer), and the time within which such person must accept such offer, which shall in no event exceed thirty (30) days from the date upon which the Administrator made the determination to grant the Stock Purchase Right. The offer shall be accepted by execution of a Restricted Stock purchase agreement in the form determined by the Administrator. Shares purchased pursuant to the grant of a Stock Purchase Right shall be referred to herein as "Restricted Stock."

    (b)  Repurchase Option.  Unless the Administrator determines otherwise, the Restricted Stock purchase agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser's employment with the Company for any reason (including death or disability). The purchase price for Shares repurchased pursuant to the Restricted Stock purchase agreement shall be the original purchase price paid the purchaser and may be paid by cancellation of any indebtedness of the Purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator may determine.

    (c)  Other Provisions.  The Restricted Stock purchase agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock purchase agreements need not be the same with respect to each purchaser.

    (d)  Rights as a Shareholder.  Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to those of a shareholder, and shall be a shareholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 13 of the Plan.

    12.  Stock Withholding to Satisfy Withholding Tax Obligations.  At the discretion of the Administrator, Optionees may satisfy withholding obligations as provided in this paragraph. When an Optionee incurs tax liability in connection with an Option or Stock Purchase Right, which tax liability is subject to tax withholding under applicable tax laws, and the Optionee is obligated to pay the Company an amount required to be withheld under applicable tax laws, the Optionee may satisfy the withholding tax obligation by one or some combination of the following methods: (a) by cash payment, or (b) out of Optionee's current compensation, (c) if permitted by the Administrator, in its discretion, by surrendering to the Company Shares that (I) in the case of Shares previously acquired from the Company, have been owned by the Optionee for more than six months on the date of surrender, and (ii) have a fair market value on the date of surrender equal to or less than Optionee's marginal tax rate times the ordinary income recognized,


or (d) by electing to have the Company withhold from the Shares to be issued upon exercise of the Option, or the Shares to be issued in connection with the Stock Purchase Right, if any, that number of Shares having a fair market value equal to the amount required to be withheld. For this purpose, the fair market value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined (the "Tax Date").

    Any surrender by a Reporting Person of previously owned Shares to satisfy tax withholding obligations arising upon exercise of this Option must comply with the applicable provisions of Rule 16b-3.

    All elections by an Optionee to have Shares withheld to satisfy tax withholding obligations shall be made in writing in a form acceptable to the Administrator and shall be subject to the following restrictions:

    In the event the election to have Shares withheld is made by an Optionee and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Optionee shall receive the full number of Shares with respect to which the Option or Stock Purchase Right is exercised but such Optionee shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date.

    13.  Adjustments Upon Changes in Capitalization, Corporate Transactions.  


    14.  Non-transferability of Options and Stock Purchase Rights.  Options and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution; provided, however, that the Administrator may in its discretion grant transferable Nonstatutory Stock Options pursuant to option agreements specifying (i) the manner in which such Nonstatutory Stock Options are transferable and (ii) that any such transfer shall be subject to the Applicable Laws. Options and Stock Purchase Rights may be exercised or purchased during the lifetime of the Optionee or Stock Purchase Rights Holder only by the Optionee, Stock Purchase Rights Holder or a transferee permitted by this Section 14.

    15.  Time of Granting Options and Stock Purchase Rights.  The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such other date as is determined by the Board. Notice of the determination shall be given to each Employee or Consultant to whom an Option or Stock Purchase Right is so granted within a reasonable time after the date of such grant.

    16.  Amendment and Termination of the Plan.  

    17.  Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant to the exercise of an Option or Stock Purchase Right unless the exercise of such Option or Stock Purchase Right and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any Stock Exchange. As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by law.

    18.  Reservation of Shares.  The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority


is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

    19.  Agreements.  Options and Stock Purchase Rights shall be evidenced by written agreements in such form as the Administrator shall approve from time to time.

    20.  Shareholder Approval.  

    21.  Information to Optionees.  The Company shall provide to each Optionee, during the period for which such Optionee has one or more Options outstanding, copies of all annual reports and other information which are provided to all shareholders of the Company.
