Dear Bill:

You play an important role at PayPal and your continued engagement is important to PayPal’s success. In recognition of the important role you play, you will be eligible to receive the following retention incentives. Except as otherwise described in this letter, all terms of your employment letter of September 25, 2013, including the “at will” nature of your employment, will remain in full force and effect.

Retention Arrangement

As part of your retention arrangement, the two grants of restricted stock units awarded to you on January 15, 2014, have been modified to provide that, following the vesting of 25 percent of the units subject to each grant on January 15, 2016, 1/48th of the shares subject to each grant will vest each month thereafter.

If you remain employed with PayPal through February 1, 2016, and, prior to the full vesting of the grants, you: (1) subsequently elect to resign from your employment and (2) do not qualify for the severance protection for a voluntary resignation for “Good Reason” described in the “Termination During a Change in Control Period” paragraphs below, then you will be eligible to receive a cash payment equal to the value of the equity subject to the two grants of restricted stock units awarded to you by eBay on January 15, 2014, that would otherwise have vested in the six months following the effective date of your termination (the “Retention Payment”), subject to you executing and not revoking the Company’s standard form of release within 60 days of your termination of employment (which shall also contain customary exceptions for your continued indemnification and coverage under D&O policies, exclusions for vested benefits under retirement and welfare benefit plans and equity incentive plans, and reasonable post-employment cooperation covenants (but for the avoidance of doubt no restrictive covenants or other covenants imposing limitations on your post-employment activities (the “Release”)). Subject to the Section 409A paragraph in the “Tax and Other Matters” section below in this letter, the Retention Payment shall be payable not later than 30 days after you execute a Release and any revocation period has expired, provided that if the 60-day time period following your termination of employment spans two calendar years, the Retention Payment shall be provided as of the later of the date the Release becomes irrevocable or the first calendar day of the calendar year following the year in which your employment terminates. For the avoidance of doubt, if you are eligible for a payment under the section labeled “Termination During a Change in Control Period,” you will be entitled to the severance protections described below and you will not be entitled to the Retention Payment described in this paragraph as an additional payment.

Severance Protections

Although your employment with the Company shall be “at-will” as set forth below, you will be entitled to severance protection in certain circumstances, as described below, subject in all instances to you executing and not revoking the Release within 60 days of your termination of employment, with such amounts or benefits to be paid and/or provided as of the dates described below, provided that if the 60-day time period following your termination of employment spans two calendar years, they shall be provided as of the later of the date the Release becomes irrevocable or the first calendar day of the calendar year following the year in which your employment terminates.

Subject to approval by the Compensation Committee of the eBay Board of Directors, you will be eligible for the following:

Termination Outside a Change in Control Period. If, outside a Change in Control Period (as defined below), your employment is terminated by the Company without Cause (as defined below), then the Company shall provide you with (a) the Accrued Benefits and (b) a lump sum severance payment, payable not later than 30 days after you execute a Release and any revocation period has expired, in an amount equal to the sum of:

(i) one times the sum of (a) your Annual Base Salary and (b) your Bonus Amount; and

(ii) notwithstanding any election you may have made to defer any portion of any RSUs or PBRSUs, a cash amount equal to the value of any other eBay equity awards that are outstanding and unvested as of the date of your termination of employment which, but for such termination, otherwise would have become vested pursuant to their respective vesting schedules within 12 months following the date of such termination (with such value calculated based on the Valuation Assumptions).

Termination During a Change in Control Period. If, during a Change in Control Period, your employment is terminated by the Company without Cause or if you voluntarily resign for Good Reason, then the Company shall provide you with (a) the Accrued Benefits and (b) a lump sum severance payment, payable not later than 30 days after you execute the Release and any revocation period has expired, in an amount equal to the sum of:

(i) two times the sum of (a) your Annual Base Salary and (b) your Bonus Amount; and

(ii) notwithstanding any election you may have made to defer any portion of any RSUs or PBRSUs, a cash amount equal to the value of all then unvested eBay equity awards that are outstanding and unvested as of the date of termination of employment (with such value calculated based on the Valuation Assumptions).

Special Treatment of Equity Awards on Death/Permanent Disability. In the event that your employment with eBay terminates due to your death or disability (within the meaning of eBay’s long-term disability plan), within thirty (30) days after the date of such termination of employment, you will receive a cash payment equal to the value of any eBay equity awards that were

outstanding and unvested as of the date of such termination which, but for such termination, otherwise would have become vested pursuant to their respective vesting schedules within 24 months following the date of such termination (with such value calculated based on the Valuation Assumptions).

Tax and Other Matters.

Section 409A. The Company may withhold from any amounts payable to you such Federal, state, local or foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation. It is intended that the payments and benefits provided under this Letter shall comply with the provisions of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”) and the regulations relating thereto, or an exemption to Section 409A, and this Letter shall be interpreted accordingly. Any payments or benefits that qualify for the “short-term deferral” exception or another exception under Section 409A shall be paid under the applicable exception. Each payment under this Letter will be treated as a separate payment for purposes of Section 409A. Notwithstanding anything to the contrary herein, a termination of employment shall not be deemed to have occurred for purposes of any provision of this Letter providing for the payment of amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Letter, references to a “resignation,” “termination,” “termination of employment” or like terms shall mean separation from service. If you become entitled to a payment of nonqualified deferred compensation as a result of your termination of employment and at such time you are a “specified employee” (within the meaning of Section 409A and as determined in accordance with the methodology established by the Company as in effect on your date of termination), such payment will be postponed to the extent necessary to satisfy Section 409A, and any amounts so postponed will be paid in a lump sum on the first business day that is six months and one day after your separation from service (or any earlier date of your death). If the compensation and benefits provided under this Letter would subject you to taxes or penalties under Section 409A, the Company and you will cooperate diligently to amend the terms of this Letter to avoid such taxes and penalties, to the extent possible under applicable law.

Change in Control Golden Parachute Excise Taxes. In the event of a Change in Control, where an accounting firm designated by the Company determines that the aggregate amount of the payments and benefits that (but for the application of this paragraph) would be payable to you under this Letter agreement or any other plan, policy or arrangement of the Company and any of their affiliates, exceeds the greatest amount of payments and benefits that could be paid or provided to you without giving rise to any liability for any excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then you may elect either to (1) pay the Excise Tax and receive all such payments and benefits as may be payable to you, or (2) only receive the aggregate amount of such payments and benefits payable or to be provided to you that would not exceed the amount that produces the greatest after-tax benefit to you after taking into account any Excise Tax and other taxes that would otherwise be payable by you (such reduced amount of payments and benefits, the “Reduced Benefit Amount”). In the event you elect to receive the Reduced Benefit Amount, however, the reduction in such payments or benefits pursuant to the immediately preceding sentence shall be made in the following order: (1) by reducing severance payments based on your Annual Base Salary and Bonus Amount, if any is then payable, and then (2) by reducing amounts in respect of any equity-based awards (first in the form of cash payments, if any are due hereunder, then in respect of any vesting of any such awards hereunder, and only thereafter in respect of any vesting of any such awards under any other plan or arrangement).

Definitions.

Very truly yours,
