Incentive Stock Option:

THIS INCENTIVE STOCK OPTION AGREEMENT (this “Agreement”) dated as of the       day of                , 20     , by and between EarthLink, Inc., a Delaware corporation (the “Company”), and                      (“Participant”) is made pursuant and subject to the provisions of the                      Plan (the “Plan”), a copy of which is attached hereto.  All terms used herein that are defined in the Plan have the same meaning given them in the Plan.

1.                                   Grant of Incentive Stock Option.  Pursuant to the Plan, the Company, on                , 20      (the “Date of Grant”), granted to Participant, subject to the terms and conditions of the Plan and subject further to the terms and conditions herein set forth, the right and option to purchase from the Company all or any part of an aggregate of            shares of Common Stock at the option price of $           per share, such option price per share being not less than the Fair Market Value of a share of the Common Stock on the Date of Grant (or, in case of a Ten Percent Shareholder as described in the Plan, not less than 110 percent of the Fair Market Value of a share of the Common Stock on the Date of Grant). This Option is to be treated as an Incentive Stock Option; except, however, if the aggregate Fair Market Value, determined at the time of grant, of shares of Common Stock with respect to which Participant may exercise Incentive Stock Options for the first time during any calendar year under the Plan and any other plan of the Company exceeds $100,000, the Incentive Stock Options that cause the limitation to be exceeded shall be treated as Nonqualified Stock Options. . This Incentive Stock Option is exercisable as hereinafter provided.

2.                                       Terms and Conditions.  This Incentive Stock Option is subject to the following terms and conditions:

(a)                                  Expiration Date.  This Incentive Stock Option shall expire at 11:59 p.m. on                , 20      (the “Expiration Date”).  In no event shall the Expiration Date be later than 10 years from the Date of Grant (or, in case of a Ten Percent Shareholder as described in the Plan, five years from the Date of Grant).

(b)                                 Exercise of Option.  Except as provided in the Plan and in paragraphs 3, 4, 5, 6 or 7, this Incentive Stock Option shall be exercisable with respect to Twenty-Five Percent (25%) of the shares of Common Stock subject to the Option on the first annual anniversary of the Date of Grant and then with respect to another Six and One Quarter Percent (6.25%) of the Shares of Common Stock subject to this Option on each quarterly (three-month) anniversary thereafter until this Option has become exercisable with respect to One Hundred Percent (100%) of the shares of Common Stock subject to this Option, provided Participant is still employed by

the Company or any Subsidiary at each such time.  Once this Incentive Stock Option has become exercisable in accordance with the preceding sentence, it shall continue to be exercisable until the earlier of the termination of the Participant’s rights hereunder pursuant to paragraphs 3, 4, 5, 6 or 7 or until the Expiration Date.  A partial exercise of this Incentive Stock Option shall not affect Participant’s right to exercise this Incentive Stock Option with respect to the remaining shares, subject to the conditions of the Plan and this Agreement.

(c)                                  Method of Exercise and Payment for Shares.  This Incentive Stock Option shall be exercised by delivering written notice to the attention of the Company’s Secretary or his designee at the Company’s principal office located at 1375 Peachtree Street, Level A, Atlanta, GA 30309.  The exercise date shall be (i) in the case of notice by mail, the date of postmark, or (ii) if delivered in person, the date of delivery.  Such notice shall be accompanied by payment of the Option price in full, in cash or cash equivalent acceptable to the Administrator, or, if the Administrator in its discretion permits, (i) by the surrender of shares of Common Stock that Participant has owned for at least six months with an aggregate Fair Market Value (determined as of the preceding business day) which, together with any cash or cash equivalent Participant pays, is not less than the Option price of the number of shares of Common Stock for which the Incentive Stock Option is being exercised, (ii) by a cashless exercise through a broker, (iii) by such other medium of payment as the Administrator in its discretion shall authorize or (iv) by any combination of the aforementioned methods of payment.

(d)                                 Nontransferability.  This Incentive Stock Option is nontransferable except by will or by the laws of descent and distribution.  During Participant’s lifetime, only Participant may exercise this Incentive Stock Option. No right or interest of Participant in this Incentive Stock Option shall be liable for, or subject to, any lien, obligation or liability of the Participant.

(e)                                  Shareholder Rights.  Participant shall not have any rights as a shareholder with respect to shares of Common Stock subject to this Incentive Stock Option until the proper exercise of such Incentive Stock Option, the payment of the Option price and any applicable withholding taxes, and the issuance to Participant of the certificates representing the shares of Common Stock for which the Incentive Stock Option is exercised.

3.                                       Exercise in the Event of Death.  This Incentive Stock Option shall be exercisable for all or part of the number of shares of Common Stock that Participant is entitled to purchase pursuant to paragraph 2(a) and (b) as of the date of Participant’s death, reduced by the number of shares for which Participant previously exercised the Incentive Stock Option, in the event Participant dies while employed by the Company or any Subsidiary and prior to the Expiration Date and prior to the termination of the Participant’s rights under paragraphs 4, 5, 6 or 7.  In that event, this Incentive Stock Option may be exercised by Participant’s estate, or the person or persons to whom Participant’s rights under this Incentive Stock Option shall pass by will or the laws of descent and distribution.  In that event, Participant’s estate or such persons may exercise this Incentive Stock Option during the remainder of the period preceding the Expiration Date or within 180 days of the date Participant dies, whichever is shorter.
