Re: Letter Amendment to Performance Stock Option (the “Option”)

Dear Xxx:

I’m pleased to inform you of the 2015 performance-vesting methodology established by the Compensation and Leadership Development Committee (the “Compensation Committee”) for the Performance Stock Option Agreement between you and Yahoo! Inc. (the “Company”) dated November 29, 2012, as amended April 14, 2014 (the “Original Agreement”). Capitalized terms used in this letter agreement and the attached exhibit and not otherwise defined herein or therein are used as defined in the Original Agreement.

The Compensation Committee has established GAAP revenue, revenue ex-TAC and adjusted EBITDA as the Option’s new Performance Metrics. Accordingly, effective with the 2015 Performance Year, Appendix A to the Original Agreement is amended and restated in its entirety to read as set forth on Appendix A to this letter agreement.

This letter agreement does not modify any other terms of the Original Agreement except as expressly set forth above. (For the avoidance of doubt, no amendment is made to the vesting provisions of the Original Agreement as applicable to any Performance Period prior to 2015).

If this letter accurately sets forth our agreement with respect to the foregoing matters, please sign the enclosed copy of this letter and return it to me.

YAHOO! INC.

Appendix A - 2012 Performance Option

Vesting of Option

Subject to Sections 6 and 7 of the Original Agreement, the Annual Tranche for 2015 shall be eligible to vest in accordance with this Appendix A.

Performance Year		Vesting Date
2015			January 26, 2016

• For the Performance Year, the “Performance Metrics” and “Weightings” shall be as follows: GAAP Revenue (one-third), Revenue ex-TAC (one-third), and Adjusted EBITDA (one-third).

• For each Performance Metric, the Administrator has established a performance target (“Goal”) for the Performance Year. The Goals will be communicated to the Optionee.

• After the end of 2015, the Company’s actual results for each Performance Metric shall be adjusted for purposes of this Option as set forth in “Definitions and Adjustments,” below.

• For each Performance Metric, a vesting percentage (each, a “Component Vesting Percentage”) shall be calculated based on the Company’s actual performance (as adjusted) for the Performance Year as follows (with actual performance expressed as a percentage of the applicable Goal):

GAAP Revenue Actual Performance (as adjusted) relative to Goal		Component Vesting Percentage
80% or less		0%
100%		100%
106% or more		130%

Revenue Ex-TAC Actual Performance (as adjusted) relative to Goal		Component Vesting Percentage
80% or less		0%
100%		100%
106% or more		130%

Adjusted EBITDA Actual Performance (as adjusted) relative to Goal		Component Vesting Percentage
60% or less		0%
100%		100%
112% or more		130%

• If the Company’s actual performance (as adjusted), as to a particular Performance Metric, is between two levels specified in the applicable table above, the Component Vesting Percentage for such metric shall be determined by linear interpolation between the vesting percentages specified for those two levels in such table (without rounding the result).

A-1

• For each Performance Metric, a weighted vesting percentage (each, a “Weighted Vesting Percentage”) shall be calculated by multiplying such metric’s Component Vesting Percentage by such metric’s Weighting, and rounding the product to the nearest one-hundredth of one percent. In no event shall any Weighted Vesting Percentage exceed 43.33 percent.

• The overall vesting percentage applicable to the 2015 Annual Tranche (the “Overall Vesting Percentage”) shall equal the sum of the three Weighted Vesting Percentages, with such sum rounded to the nearest one percent; provided, however, that the Overall Vesting Percentage shall not exceed 100 percent.

• For the 2015 Annual Tranche, the number of options that vest shall be determined by applying the Overall Vesting Percentage to the number of shares underlying the Annual Tranche, and rounding down to the nearest whole share.

• Regardless of the vesting dates shown above, the vested portion of the Annual Tranche shall become exercisable on the date of the Administrator’s vesting determination described below.

The Administrator shall, following the end of the 2015 Performance Year, determine whether and the extent to which the applicable Goals have been satisfied and the vesting percentage of the 2015 Annual Tranche. Such determinations by the Administrator shall be final and binding. Any portion of the 2015 Annual Tranche that is not vested after giving effect to the Administrator’s determination for the Performance Year shall terminate as of the final day of such Performance Year.

Definitions and Adjustments

Definitions. For purposes of the Option, the following definitions will apply:

• “Adjusted EBITDA” as to a particular year means the Company’s income from operations before depreciation, amortization, restructuring charges (and reversals), goodwill and intangible asset impairment charges, and stock-based compensation expense for such year, as such items are determined by the Company and reflected in its reporting of financial results.

• “Annual Tranche” means the one-third (1/3) of the “Total Number of Shares Granted” (as set forth in the Notice of Grant) that are eligible to vest with respect to the Performance Year.

• “Financial Plan” for a particular year means the Company’s final financial plan for such year reviewed by the Board of Directors in advance of such year.

• “GAAP” means U.S. generally accepted accounting principles.

Adjustments. When calculating GAAP Revenue, Revenue ex-TAC, and Adjusted EBITDA for purposes of determining actual performance for a Performance Year, the Company’s actual GAAP Revenue, Revenue ex-TAC, and Adjusted EBITDA for such year shall be adjusted (without duplication) for the following items to the extent such items were not included in the Financial Plan for such year:

(a) increased or decreased to eliminate the financial statement impact of acquisitions with a GAAP purchase price of $500 million or more and costs associated with such acquisitions;

(b) increased or decreased to eliminate the financial statement impact of divestitures with a GAAP sale price of $500 million or more and costs associated with such divestitures;
