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

Dear Marissa:

I’m pleased to confirm the 2015 performance-vesting methodology established by
the Compensation and Leadership Development Committee (the “Compensation
Committee”) for the Performance Stock Option Agreement (Mayer Retention Grant)
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.

/s/ Allan McCall

Allan McCall

Sr. Director, Compensation

Acknowledged and Agreed:

Appendix A - 2012 Performance Option (Mayer Retention Grant)

Vesting of Option

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

 

Performance Year

   Vesting Date  

2015

     January 26, 2016   

2016

     January 26, 2017   

 

  •   For each 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 2015 Performance Year. At the start of 2016,
the Administrator will establish Goals for the 2016 Performance Year. The Goals
will be communicated to the Optionee after they are established by the
Administrator.

 

  •   After the end of each year, 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

   100%

A-1

--------------------------------------------------------------------------------

  •   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).

 

  •   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 an 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 each year’s Annual Tranche, the number of options that vest shall be
determined by applying the Overall Vesting Percentage for such year to the
number of shares underlying such year’s Annual Tranche, and rounding down to the
nearest whole share.

 

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

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

Maximum Vesting. Notwithstanding any other provision herein, in no event shall
any Annual Tranche vest as to more than one hundred percent (100%) of the
options subject to the Annual Tranche.

compensation expense for such year, as such items are determined by the Company
and reflected in its reporting of financial results.
