Dear David:

On behalf of Yahoo! Inc. (“Yahoo!” or the “Company”), I am pleased to offer you the position of senior Vice President, Production Operations, reporting to Aristotle Balogh working in US - Sunnyvale and hope that you will accept this offer. If you’re up for the challenge, get ready to yodel. Your starting base salary will be $31,250 per month ($375,000.00 annually), less applicable taxes, deductions, and withholdings, paid semi-monthly and subject to annual review. For purposes of this letter, your first day of work at Yahoo! will be considered your “Employment Start Date.”

Sign-On Bonus. You will receive a one-time sign-on bonus in the amount of $100,000.00 less applicable taxes, deductions and withholdings. This will be payable to you on the first semi-monthly paycheck that occurs 30 days after your Employment Start Date. If you voluntarily resign from your employment with Yahoo! during the first twelve (12) months following your Employment Start Date, this sign-on bonus, (Net of withheld taxes) will become due and payable by you to Yahoo! on your last day of employment.

Stock Options. As a part of the Yahoo! team, we strongly believe that ownership of the Company by Yahoos is an important factor to our success. Therefore, as part of your compensation, management will recommend that the Compensation Committee of the Board of Directors grant you an option to purchase 150,000 shares of Yahoo! Inc.’s common stock. The exercise price for this option will be the fair market value of Yahoo! common stock on the date of grant as determined by the Compensation Committee. The option will be subject to the terms and conditions of Yahoo! Inc.’s 1995 Stock Plan, as amended, and the applicable notice of stock option grant and stock option agreement (which will include the stock option vesting schedule), and vesting of the option is contingent on your continued employment with Yahoo! through each vesting date.

Restricted Stock Units. In addition, management will also recommend that the Compensation Committee of the Board of Directors grant you an award of 60,000 Restricted Stock Units (“RSUs”), subject to the terms and conditions of the Yahoo! Inc. 1995 Stock Plan, as amended, and the applicable restricted stock unit award agreement. The RSUs will vest on the third anniversary of the date of grant, provided that you have been continuously employed with Yahoo! through such date. Following the vesting of the RSUs, you will receive one share of Yahoo! Inc. common stock for each vested RSU (subject to tax withholding).

Management Incentive Plan. If your Employment Start Date is on or before October 1, 2009, you also will be eligible to participate in the 2009 Management Incentive Plan (MIP), with a target incentive of 50% of your annual base salary, pro-rated based on the period of time you are employed at Yahoo! in a MIP eligible position during the relevant year, less applicable taxes, deductions, and withholdings. Target incentives do not constitute a promise of payment. Your actual MIP payout will depend on Yahoo! financial performance and management’s assessment of your group and individual performance, and it is subject to, and governed by, the terms and requirements of the MIP plan document. Eligibility for participation in the MIP plan is subject to annual review.

Change In Control Severance Plan. Under the Yahoo! Inc. Change in Control Employee Severance Plan (“Severance Plan”), if you are a full-time regular employee employed by Yahoo! on the date of a “Change in Control” and your employment is terminated without “Cause”· or you resign for “Good Reason” within two years following a Change in Control (a “Severance”), you will be eligible for the following severance benefits: (1) continuation of your then current annual base salary for 18 months; (2) continuation of your group health insurance

benefits for 18 months; (3) reimbursement of up to $15,000.00 for outplacement services; and (4) acceleration of your unvested equity awards so that such awards become fully vested and exercisable as of the date of termination. These severance benefits are subject to the terms of the Severance Plan and receipt is conditioned upon your signing and not revoking a release of claims against the Company. The amounts of the severance benefits referenced in this letter are based on the level of the position you are being offered herein. In the event that you hold a different position at the time of a Severance, the amounts for which you are eligible could differ.

Benefits. A significant part of your total compensation at Yahoo! is derived from the benefits that Yahoo! provides. Yahoo! provides a very competitive benefits package for its eligible full- and part-time employees. Eligible Yahoos may participate in Yahoo!’s health insurance benefits (medical, dental and vision), life insurance, short term and long term disability, the Employee Stock Purchase Plan, 401(k) Plan, and Yahoo’s Flexible Spending Plan (Healthcare Reimbursement Account and/or Dependent Care Reimbursement Account). Yahoos working less than 40 hours per week may not be eligible for all benefit programs or certain benefits may be provided on a pro-rated basis. Please refer to benefit plan documents for eligibility. Of course, Yahoo! may change its benefits at any time. Prior to New Hire Orientation, you will be provided a website address and logon instructions to access detailed information about Yahoo! benefits programs, including the plan documents.

Paid Time Off. You will accrue vacation at a rate of fifteen (15) days for the first year of your employment at Yahoo!. Thereafter, you will accrue vacation at the regular Yahoo! vacation accrual rate. Vacation is accrued based on hours worked, therefore Yahoos who work a part-time schedule accrue vacation on a pro-rata basis. ln addition, Yahoo! currently provides eligible employees with ten (10) paid holidays and two (2) personal floating holidays each year.
