SEVERANCE PACKAGE. In exchange for the mutual covenants set forth in this letter, on the eighth day after your execution of this Agreement, provided that you have not exercised your right of rescission under the Older Worker Benefits Protection Act ("OWBPA"), as set forth in Section 6 below, Akamai agrees to accelerate the vesting of 393,750 shares of restricted stock that was issued to you under the Company's Second Amended and Restated 1998 Stock Incentive Plan (the "Plan") and the Restricted Stock Agreement ("RSA") between you and the Company. The Company will exercise its Purchase Option (as defined in the RSA) with respect to all shares of restricted stock that are not vested as of the Separation Date and are not accelerated pursuant to this Agreement, i.e., 236,250 shares. This Section 2 shall constitute written notice of the Company's exercise of its Purchase Option. You agree that within ten days of your execution of this Agreement, you will tender to the Company the certificate or certificates representing the shares as to which the Company is exercising its Purchase Option. As soon as practicable after receipt and cancellation of the repurchased shares, the Company will pay you the original purchase price for those shares, or $9,581.62. Except as set forth in this Section 2, all of the terms, rights, obligations and conditions of the Plan that you were eligible for or participated in during your employment with Akamai, and any documents executed by you pursuant to the Plan are hereby incorporated by reference and shall survive the signing of this Agreement. You acknowledge and agree that from and after the Separation Date, you shall not have any rights to vest in any stock options or restricted stock under any Akamai stock or stock option plan (of whatever name or kind) that you participated in or were eligible to participate in during your employment. You acknowledge and agree that the Severance Package provided in this Agreement is not otherwise due or owing to you under any Akamai policy or practice, and that the Severance Package to be provided to you is not intended to, and shall not constitute, a severance plan, and shall confer no benefit - -------- 1/ For the purposes of this Agreement, the parties agree that the term "Akamai" is intended to include Akamai Technologies, Inc. and any other divisions, affiliates and subsidiaries, and its and their respective officers, directors, agents and assigns. 2 Letter Agreement for Earl Galleher April 2, 2001 Page 2 on anyone other than the parties hereto.
