(1)           Employer or an Affiliate shall pay Employee Cash Severance in one lump sum payment, subject to all applicable withholdings and employment taxes and subject to reductions pursuant to Sections 4 and 16 of this Plan, as soon as practical (and within 30 days) after the Employee’s Termination of Employment, subject to any required delays under Sections 2(a)(4) or 4 below.

(2)           The Employer or an Affiliate shall pay any and all amounts with respect to COBRA continuation coverage that the Employee elects under any Welfare Plan of the Employer or an Affiliate for him or her or his or her spouse or dependents through the Benefits Severance Period, including all attendant administrative fees and expenses, however described or denominated.  All such payments shall be made, no less frequently than monthly, in such manner as to permit Employee to continue his or her COBRA coverage on a timely basis; provided that the Company will make all such payments as soon as administratively practicable, subject to any required delays under Sections 2(a)(4) or 4 below.

(3)           The Employee or his Beneficiary, or any other person entitled to receive benefits with respect to the Employee under any Retirement Plan, Welfare Plan, or other plan or

(b)           If the Employee has a Termination of Employment by the Employer or an Affiliate or by the Employee other than under the circumstances set forth in Section 2(a), including without limitation on the death or On Account of Disability of the Employee, by the Employer or an Affiliate for Cause or by the Employee other than for Good Reason, then the Employee’s compensation shall be paid through the date of his or her Termination of Employment (no less frequently than monthly and consistent with Employer’s customary payroll practices), and the Employer and its Affiliates shall have no further obligation with respect to the Employee under this Plan.  Such Termination of Employment shall have no effect upon an Employee’s other rights, including but not limited to rights under any Retirement Plan, Welfare Plan or other plan or program in which Employee participates, the amount, form and time of payment of such benefits to be determined by the terms of such Retirement Plan, Welfare Plan, or other plan or program.

(c)           This Section 2 shall have no effect, and Employer shall have no obligations hereunder with respect to, an Employee who has a Termination of Employment for any reason at any time other than within eighteen (18) months after a Change in Control of the Employer occurs under the circumstances described in Section 2(a) above.

(d)           The Employer or Affiliate that employs the Employee on his or her Termination of Employment will fund the payments to be made under the Plan to such Employee from its general assets.

3.                                       Accelerated Vesting of Options and Restricted Stock Units.

(a)           (i)            In the event no provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with a Change in Control of the Employer of outstanding stock options the Employer or an Affiliate granted before the Change in Control of the Employer, then contemporaneously with the Change in Control of the Employer, all outstanding stock options that the Employer or any Affiliate previously granted to an Employee in either the Gold or Silver Benefit Category shall be exercisable in full, if not then already fully exercisable, in accordance with the terms of such options and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the stock options or plans to the contrary regarding the exercisability of such options.  If provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with the Change in Control of the Employer of outstanding stock options the Employer or an Affiliate granted before the Change in Control of the Employer, then on the Employee’s Termination of Employment on or after a Change in Control of the Employer occurs, all outstanding stock options that the Employer or any Affiliate previously granted to an Employee in either the Gold or Silver Benefit Category shall be exercisable in full, if not then already fully exercisable, in accordance with the terms of such options and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the stock options or plans to the contrary regarding the exercisability of such stock options.

(ii)           In the event no provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with a Change in Control of the Employer of outstanding stock options the Employer or an Affiliate granted before the Change in Control of the Employer, then contemporaneously with the Change in Control of the Employer, all outstanding stock options that the Employer or any Affiliate previously granted to an Employee in the Bronze Benefit Category shall be exercisable, in accordance with the terms of such options and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the stock options or plans to the contrary regarding the exercisability (and only exercisability) of such options, on at least the basis they would have been exercisable had Employee remained employed with the Employer or any Affiliate for twenty-four (24) months after the Change in Control of the Employer occurs, if not then already exercisable to such extent.  If provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with the Change in Control of the Employer of outstanding stock options the Employer or an Affiliate granted before the Change in Control of the Employer, then on the Employee’s Termination of Employment on or after a Change in Control occurs, all outstanding stock options that the Employer or any Affiliate previously granted to an Employee in the Bronze Benefit Category shall be exercisable, in accordance with the terms of such options and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the stock options or plans to the contrary regarding the exercisability (and only exercisability) of such stock options, on at least the basis they would have been exercisable had Employee remained employed with the Employer or an Affiliate for twenty-four (24) months after the Change in Control of the Employer occurs, if not then already exercisable to such extent.

(iii)          It is deemed under this Plan that the Employer or an Affiliate consistent with the plans and agreements governing the applicable stock options accelerated the exercisability of such outstanding stock options at such time and on such basis.  Notwithstanding any other provision of this Plan, this Section 3 only impacts the exercisability and vesting of the

10

applicable stock option; it is not intended to nor does it extend the terms or expiration dates of the applicable stock options.

(iv)          Notwithstanding any of the foregoing, for purposes of this Section 3 only, an Employee in the Bronze Benefit Category who previously participated in the EarthLink, Inc. Accelerated Vesting and Compensation Continuation Plan and who elected to participate in this Plan and waive any and all rights to benefits he or she had under the EarthLink, Inc. Accelerated Vesting and Compensation Continuation Plan shall be treated for purposes of this Section 3 as if he or she were in the Silver Benefit Category solely for purposes of the accelerated vesting of stock options.  Exhibit C attached hereto shall show the names of each employee who is included in the foregoing position and who is entitled to the treatment described in this Section 3(a)(iv) if they become an Employee under this Plan.

(v)           Exhibit B attached hereto provides a summary of the accelerated vesting to which an Employee will be entitled based on the Benefit Category for which such Employee qualifies.  In the event of any conflict between such summary and the terms of Section 3 of the Plan, the provisions of Section 3 of the Plan shall govern.

(b)           (i)            In the event no provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with a Change in Control of the Employer of outstanding restricted stock units the Employer or an Affiliate granted before the Change in Control of the Employer, then contemporaneously with the Change in Control of the Employer, all outstanding restricted stock units that the Employer or any Affiliate previously granted to an Employee in either the Gold or Silver Benefit Category shall be earned and payable in full, if not then already fully earned and payable, in accordance with the terms of such restricted stock units and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the restricted stock units or plans to the contrary regarding their becoming fully earned and payable; provided that a restricted stock unit that contains performance criteria shall not become fully earned and payable if the date, if any, for attainment of the performance criteria on which such restricted stock unit would have become fully earned and payable has passed as of the date of the Change of Control.  If provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with the Change in Control of the Employer of outstanding restricted stock units the Employer or an Affiliate granted before the Change in Control of the Employer, then on the Employee’s Termination of Employment on or after a Change in Control of the Employer occurs, all outstanding restricted stock units that the Employer or any Affiliate previously granted to an Employee in either the Gold or Silver Benefit Category shall be earned and payable in full, if not then already fully earned and payable, in accordance with the terms of such restricted stock units and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the restricted stock units or plans to the contrary regarding their becoming fully earned and payable; provided that a restricted stock unit that contains performance criteria shall not become fully earned and payable if the date, if any, for attainment of the performance criteria on which such restricted stock unit would have become fully earned and payable has passed as of the date of the Change of Control.

(ii)           In the event no provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with a Change in Control of the Employer of outstanding restricted stock units the Employer or an Affiliate granted before the

11

Change in Control of the Employer, then contemporaneously with the Change in Control of the Employer, all outstanding restricted stock units that the Employer or any Affiliate previously granted to an Employee in the Bronze Benefit Category shall be earned and payable, in accordance with the terms of such restricted stock units and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the restricted stock units or plans to the contrary regarding their becoming fully earned and payable on at least the basis they would have been earned and payable had Employee remained employed with the Employer or any Affiliate for twenty-four (24) months after the Change in Control of the Employer occurs, if not then already earned and payable to such extent; provided that a restricted stock unit that contains performance criteria shall not become fully earned and payable if the date, if any, for attainment of the performance criteria on which such restricted stock unit would have become fully earned and payable has passed as of the date of the Change of Control or occurs more than twenty-four (24) months after the date of the Change in Control.  If provision is made for the continuance, assumption or substitution by the Employer or its successor in connection with the Change in Control of the Employer of outstanding restricted stock units the Employer or an Affiliate granted before the Change in Control of the Employer, then on the Employee’s Termination of Employment on or after a Change in Control occurs, all outstanding restricted stock units that the Employer or any Affiliate previously granted to an Employee in the Bronze Benefit Category shall be earned and payable, in accordance with the terms of such restricted stock units and the applicable plans pursuant to which they were granted, notwithstanding any provisions in the restricted stock units or plans to the contrary regarding their becoming earned and payable, on at least the basis they would have been earned and payable had Employee remained employed with the Employer or an Affiliate for twenty-four (24) months after the Change in Control of the Employer occurs, if not then already earned and payable to such extent; provided that a restricted stock unit that contains performance criteria shall not become fully earned and payable if the date, if any, for attainment of the performance criteria on which such restricted stock unit would have become fully earned and payable has passed as of the date of the Change of Control or occurs more than twenty-four (24) months after the date of the Change in Control.

(iii)          It is deemed under this Plan that the Employer or an Affiliate consistent with the plans and agreements governing the applicable restricted stock units accelerated such restricted stock units becoming earned and payable at such time and on such basis.  Notwithstanding any other provision of this Plan, this Section 3 only impacts the vesting of the applicable restricted stock units; it is not intended to nor does it extend the terms or expiration dates of the applicable restricted stock units.

(iv)          Notwithstanding any of the foregoing, for purposes of this Section 3 only, an Employee in the Bronze Benefit Category who previously participated in the EarthLink, Inc. Accelerated Vesting and Compensation Continuation Plan and who elected to participate in this Plan and waive any and all rights to benefits he or she had under the EarthLink, Inc. Accelerated Vesting and Compensation Continuation Plan shall be treated for purposes of this Section 3 as if he or she were in the Silver Benefit Category solely for purposes of the accelerated vesting of restricted stock units.  Exhibit C attached hereto shall show the names of each employee who is included in the foregoing position and who is entitled to the treatment described in this Section 3(b)(iv) if they become an Employee under this Plan.

(v)           Exhibit B attached hereto provides a summary of the accelerated vesting to which an Employee will be entitled based on the Benefit Category for which such Employee

12

qualifies.  In the event of any conflict between such summary and the terms of Section 3 of the Plan, the provisions of Section 3 of the Plan shall govern.

4.                                     Release and Setoff.

Notwithstanding any other provision of this Plan, payments shall be made under the Plan to any Employee or his Beneficiary only after the Employee executes a release and waiver containing such terms and conditions as the Employer and its Affiliates may reasonably require, including non-solicitation, non-competition and confidentiality provisions on or within 21 days, (45 days in the event of a group termination) after the Employee’s Termination of Employment, but not prior to such Termination of Employment.  Each Employee’s right to participate under this Plan and to receive benefits hereunder (including the benefits described in Section 3 of the Plan) is contingent upon the Employee’s agreement to this Section 4 and his or her continued compliance with any agreements entered into hereunder.  The Employer and its Affiliates also may reduce and set-off any payments to or with respect to an Employee pursuant to this Plan by any amount the Employee or his Beneficiary may owe to Employer or any Affiliate.  Notwithstanding any other provision of this Plan, no payments shall be made or benefits provided pursuant to this Plan during the first 30 days (60 days in the event of a group termination) after the Employee’s Termination of Employment and any payments or benefits that are to be provided in that period shall be accumulated and paid (or provided or reimbursed) in a lump sum as soon as such period ends.

5.                                     Death.

If an Employee has a Termination of Employment under circumstances described in Section 2(a), then upon the Employee’s subsequent death, all unpaid amounts payable to the Employee under Section 2(a)(1) or (2) shall be paid to his Beneficiary.  Any death benefits owing under Section 2(a)(3) shall be paid as specified by the applicable Retirement Plan, Welfare Plan or other plan or program.

6.                                     Claim for Benefits.

(a)           Employees do not need to complete a claim for benefits to obtain benefits under the Plan.  However, Employees who dispute the amount of, or their entitlement to, Plan benefits must file a claim with the Employer to obtain Plan benefits.  Any claim by an Employee who disputes the amount of, or his or her entitlement to, Plan benefits must be filed in writing within ninety (90) days of the event that the Employee is asserting constitutes an entitlement to such Plan benefits.  Failure by the Employee to submit such claim within the ninety (90)-day period shall bar the Employee from any claim for benefits under the Plan as a result of the occurrence of such event.

(b)           Claims for benefits shall be filed in writing with the Employer.  Written notice of the decision on such claim shall be furnished to the claimant within ninety (90) days of receipt of such claim unless special circumstances require an extension of time for processing the claim.  If the Employer needs an extension of time to process a claim, written notice will be delivered to the claimant before the end of the initial ninety (90) day period.  The notice of extension will

13

include a statement of the special circumstances requiring an extension of time and the date by which the Employer expects to render its final decision.  However, that extension may not exceed ninety (90) days after the end of the initial period.  If the Employer rejects a claim for failure to furnish necessary material or information, the written notice to the claimant will explain what more is needed and why, and will tell the claimant that the claimant may refile a proper claim.

(c)           The Employer shall provide payment for the claim only if the Employer determines, in its sole discretion, that the claimant is entitled to the claimed benefit.

(d)           If any part of a claim for benefits under this Plan is denied, the Employer will provide the claimant with a written notice stating (i) the specific reason or reasons for the denial; (ii) the specific reference to pertinent Plan provisions on which the denial was based; (iii) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary; and (iv) appropriate information as to the steps to be taken if the claimant wishes to submit a claim for review, including a statement of the claimant’s right to bring a civil action under Section 502(a) of ERISA following an adverse benefit determination on review.

(e)           The full value of any payment made according to the Plan satisfies that much of the claim and all related claims under the Plan.

(f)            If a claim is denied, the claimant may appeal the denial by delivering a written notice to the Employer specifying the reasons for the appeal.  That notice must be delivered within sixty (60) days after receiving the notice of denial.  The claimant may submit written comments, documents, records and other information relating to the claimant’s claim for benefits.  The claimant will be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits.  The Employer’s review will take into account all such written comments, documents, records and other information the claimant submits relating to the claim, without regard to whether such information was submitted or considered initially.

(g)           The Employer will advise the claimant in writing of the final determination after review.  The decision on review will be written in a manner calculated to be understood by the claimant, and it will include specific reasons for the decision and specific references to the pertinent provisions of the Plan or related documents on which the decision is based.  Such written notification also will include a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits, the claimant’s right to obtain the information about such procedures and a statement of the claimant’s right to bring a civil action under Section 502(a) of ERISA following a denial on review.  The written decision will be rendered within sixty (60) days after the request for review is received, unless special circumstances require an extension of time for processing.  If an extension is necessary the Employer will furnish written notice of the extension to the claimant before the end of the 60-day period and indicate the special circumstances requiring the extension of time.  The extension notice will indicate the date by which the Employer expects to render a decision.  The decision will then be rendered as soon as possible, but no later than one hundred twenty (120) days after receipt of the request for review.

14

(h)           If the Employer holds regularly scheduled meetings at least quarterly, the time periods for rendering the written decision described in the preceding paragraph shall not apply and the Employer shall instead make a benefit determination no later than the date of the meeting of the Employer that immediately follows the Plan’s receipt of a request for review, unless the request for review is filed within 30 days preceding the date of such meeting.  In such case, a benefit determination may be made by no later than the date of the second meeting following the Plan’s receipt of the request for review.  If special circumstances require a further extension of time for processing, a benefit determination will be rendered no later than the third meeting of the Employer following the Plan’s receipt of the request for review.  If such an extension of time for review is required because of special circumstances, the Employer will provide the claimant with written notice of the extension, describing the special circumstances and the date as of which the benefit determination will be made, prior to the commencement of the extension.  The Employer will notify the claimant of the benefit determination as soon as possible, but not later than five days after the benefit determination is made.

(i)            In no event shall an Employee or other claimant be entitled to challenge a decision of the Employer in court or in any other administrative proceeding unless and until these claim review and appeal procedures have been complied with and exhausted.  The claimant shall have ninety (90) days from the date of receipt of the Employer’s decision on review in which to file suit regarding a claim for benefits under the Plan.  If suit is not filed within such 90-day period, it shall be forever barred.  The decisions made hereunder shall be final and binding on Employees and any other party.

7.                                       Administration of the Plan.

The Employer through its Board of Directors shall interpret and administer the Plan.  The Employer shall establish rules for the administration of the Plan.  The Employer shall have the discretionary authority to construe the terms of the Plan and shall determine all questions arising in its administration, interpretation and application, including those concerning eligibility for benefits.  All determinations of the Employer shall be final and binding on all Employees and Beneficiaries.  The Employer may appoint a committee or an agent or other representative to act on its behalf and may delegate to such committee or agent or representative any of its powers hereunder.  Any action that such committee or agent or representative takes shall be considered to be the action of the Employer, when the committee or agent or representative is acting within the scope of the authority that the Employer delegated to it, and the Employer shall be responsible for all such actions.  If the Employer appoints a committee or other agent or representative to act on its behalf, the Employer will pay all the expenses relating to such administration, and, as permitted by law, the Employer will indemnify and save each committee member or agent or representative harmless against expenses, claims, and liabilities arising out of being such committee member or agent or representative within the time, if any, required by Section 409A of the Code.  The Employer also may employ such accountants, counsel, specialists and other advisory clerical persons as it deems necessary or desirable in connection with administration of the Plan.  The Employer is entitled to rely conclusively on any opinions from its accountants or counsel.  The Employer will keep all books of account, records and other data necessary for proper administration of the Plan.

15

8.                                     Employee Assignment.

No interest of any Employee, his or her spouse or any Beneficiary under this Plan, or any right to receive any payment or distribution hereunder, shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind, nor may such interest or right to receive a payment or distribution be taken, voluntarily or involuntarily, for the satisfaction of the obligations or debts of, or other claims against, the Employee or his or her spouse or Beneficiary, including claims for alimony, support, separate maintenance, and claims in bankruptcy proceedings.

9.                                     Benefits Unfunded.

All rights under this Plan of the Employees and their spouses and Beneficiaries, shall at all times be entirely unfunded, and no provision shall at any time be made with respect to segregating any assets of Employer or any Affiliate for payment of any amounts due hereunder.  The Employees, their spouses and Beneficiaries shall have only the rights, if any, of general unsecured creditors of Employer and its Affiliates.

10.                               Applicable Law.

This Plan shall be construed and interpreted pursuant to the laws of the State of Delaware (other than its choice-of-law rules), except to the extent those laws are superceded by the laws of the United States of America.

11.                               No Employment Contract.

Nothing contained in this Plan shall be construed to be an employment contract between an Employee and the Employer or an Affiliate.  The creation, continuance or change of this Plan or any payment hereunder does not give any person a non-statutory legal or equitable right against the Employer or an Affiliate to remain employed by the Employer or an Affiliate.  This Plan does not modify the terms of any Employee’s employment.

12.                               Severability.

In the event any provision of this Plan is held illegal or invalid, the remaining provisions of this Plan shall not be affected thereby.

13.                               Successors.

The Plan shall be binding upon and inure to the benefit of Employer, its Affiliates, the Employees and their respective heirs, representatives and successors.

16

14.                               Amendment and Termination.

Notwithstanding any other provision of this Plan, Employer shall have the right (i) to declare that an individual who previously was selected to participate as an Employee in the Plan shall no longer participate as an Employee in the Plan, (ii) to amend the Plan from time to time and (iii) to terminate the Plan at any time; provided that, within four (4) months before a Change in Control of the Employer occurs or after a Change in Control of the Employer occurs, without the Employee’s consent, (i) the Employer may not declare that an individual who previously was selected to participate as an Employee in the Plan no longer participates as an Employee in the Plan, (ii) no amendment may be made that diminishes any Employee’s rights under the Plan and (iii) the Plan may not be terminated until all benefits that become payable under the Plan are paid in full.  An amendment may be made retroactively to the Plan if it is necessary to make this Plan conform to applicable law.  Upon termination of the Plan, the Plan shall no longer be of any further force or effect, and neither the Employer, any Affiliate nor any Employee shall have any obligations or rights under this Plan.  Likewise, the rights of any individual who was an Employee and whose designation as an Employee is revoked or rescinded by the Employer shall cease upon such action.

15.                               Notice.

Notices under this Plan shall be in writing and sent by registered mail, return receipt requested, to the following addresses or to such other address as the party being notified may have previously furnished to the other party by written notice:

If to Employer:

EarthLink, Inc.

1375 Peachtree Street, N.W.

Suite 7 North

Atlanta, Georgia 30309-2935

Attention: Chief People Officer

If to an Employee:

The address last indicated on the records of Employer.

16.                               Excise Tax.

Despite any other provisions of this Plan to the contrary, if the receipt of any payments or benefits under this Plan would subject an Employee to tax under Code Section 4999, the Employer may determine whether some amount of payments or benefits would meet the definition of a “Reduced Amount.”  If the Employer determines that there is a Reduced Amount, the total payments or benefits to the Employee hereunder must be reduced to such Reduced Amount, but not below zero.  If the Employer determines that the benefits and payments must be reduced to the Reduced Amount, the Employer must promptly notify the Employee of that determination, with a copy of the detailed calculations by the Employer.  All determinations of the Employer under this Section are final, conclusive and binding upon the Employee.  It is the intention of the Employer and the Employee to reduce the payments under this Plan only if the

17

aggregate Net After Tax Receipts to the Employee would thereby be increased.  Any such reduction shall first reduce any non-cash benefits on a pro-rata basis and then reduce any cash payments on a pro-rata basis.  As a result of the uncertainty in the application of Code Section 4999 at the time of the initial determination by the Employer under this Section, however, it is possible that amounts will have been paid under the Plan to or for the benefit of an Employee which should not have been so paid (“Overpayment”) or that additional amounts which will not have been paid under the Plan to or for the benefit of an Employee could have been so paid (“Underpayment”), in each case consistent with the calculation of the Reduced Amount.  If the Employer, based either upon the assertion of a deficiency by the Internal Revenue Service against the Employer or the Employee, which the Employer believes has a high probability of success, or controlling precedent or other substantial authority, determines that an Overpayment has been made, any such Overpayment must be treated for all purposes as a loan which the Employee must repay to the Employer together with interest at the applicable Federal rate under Code Section 7872(f)(2); provided, however, that no such loan may be deemed to have been made and no amount shall be payable by the Employee to the Employer if and to the extent such deemed loan and payment would not either reduce the amount on which the Employee is subject to tax under Code Section 1, 3101 or 4999 or generate a refund of such taxes.  If the Employer, based upon controlling precedent or other substantial authority, determines that an Underpayment has occurred, the Employer must pay the amount of the Underpayment to the Employee as soon as administratively practicable (and within 30 days) after the final determination of Underpayment has been made.  For purposes of this Section, (i) “Net After Tax Receipt” means the Present Value of a payment under this Plan net of all taxes imposed on the Employee with respect thereto under Code Sections 1, 3101 and 4999, determined by applying the highest marginal rate under Code Section 1 which applies to the Employee’s taxable income for the applicable taxable year; (ii) “Present Value” means the value determined in accordance with Code Section 280G(d)(4) and (iii) “Reduced Amount” means the largest aggregate amount of all payments and benefits under this Plan which (a) is less than the sum of all payments and benefits under this Plan and (b) results in aggregate Net After Tax Receipts which are equal to or greater than the Net After Tax Receipts which would result if the aggregate payments and benefits under this Plan were any other amount less than the sum of all payments and benefits to be made under this Plan.

17.                               Miscellaneous.

(a)           The failure of the Employer or an Affiliate to enforce any provisions of the Plan shall in no way be construed to be a waiver of those provisions, nor in any way effect the validity of the Plan or any part thereof, or the right of the Employer or an Affiliate thereafter to enforce such provision.

(b)           The benefits provided under this Plan are in addition to and not in lieu of any other similar benefits that the Employer or any Affiliate may specify from time to time in any employee handbook or in any other agreement between the Employee and the Employer or an Affiliate.  Additionally, the benefits that this Plan provides shall not be reduced or offset by any other payments or benefits that the Employee may receive from any other third party or other employer after the Employee’s Termination of Employment.

18

(c)           Whenever any benefits become payable under the Plan, the Employer and its Affiliates shall have the right to withhold such amounts as are sufficient to satisfy any applicable federal, state or local withholding, tax, excise tax or similar requirements.

(d)           The terms of an Employee’s benefits are as set forth in this document, which cannot be changed by the promises of any individual employee or manager.  Only the Employer may change the terms of the Plan, and then only through a written amendment.  No promises (oral or written) that are contrary to the terms of the Plan and its written amendments are binding upon the Plan or the Employer.

(e)           The terms and conditions of this Plan and the Employees’ benefits under the Plan shall remain strictly confidential.  Employees may not discuss or disclose any terms of this Plan or its benefits with anyone except their attorneys, accountants and immediate family members who shall be instructed to maintain the confidentiality agreed to under this Plan, except as may be required by law.

(f)            Benefits under the Plan are not considered eligible earnings for the Employer’s 401(k) Plan or any other benefit program.

(g)           This Plan is intended to comply with the applicable requirements of Section 409A of the Code and shall be construed and interpreted in accordance therewith.  The Employer may at any time amend, suspend or terminate this Plan, or any payments to be made hereunder, as necessary to be in compliance with Section 409A of the Code.  For purposes of this Plan, all rights to payments and benefits hereunder shall be treated as rights to receive a series of separate payments and benefits to the fullest extent allowed by Section 409A of the Code. Notwithstanding the preceding, the Employer and all Affiliates shall not be liable to any Employee or any other person if the Internal Revenue Service or any court or other authority having jurisdiction over such matter determines for any reason that any amount under this Plan is subject to taxes, penalties or interest as a result of failing to comply with Code Section 409A of the Code.

(h)           This Plan is intended to be a “Welfare Plan” and not a “Pension Plan” as defined in ERISA Sections 3(1) and 3(2), respectively.  Accordingly, the Plan must be interpreted and administered in a manner that is consistent with that intent.

19

YOUR RIGHTS UNDER ERISA

The following statement is required by law to be included in this Summary Plan Description:

As a participant in the EarthLink, Inc. Change-in-Control Accelerated Vesting and Severance Plan (the “Plan”) you are entitled to certain rights and protections under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).  ERISA provides that all Plan participants shall be entitled to:

Examine, without charge, at the Employer’s office and at other specified location, such as worksites, all Plan documents and a copy of the latest Annual Report (Form 5500 series) filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Pension and Welfare Benefit Administration.

Obtain, upon written request to the Employer, copies of all Plan documents governing the operation of the Plan and copies of the latest Annual Report (Form 5500 series) and an updated summary plan description.  The Employer may make a reasonable charge for the copies.

Receive a summary of the Plan’s annual financial report.  The Employer is required by law to furnish each Employee with a copy of this summary annual report.

In addition to creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the Plan.  The people who operate your Plan, called fiduciaries, have a duty to do so prudently and in the interest of you and other Plan participants.  No one, including your employer or any other person, may fire you or otherwise discriminate against you in any way solely in order to prevent you from obtaining a benefit or exercising your rights under ERISA.  If your claim for a benefit is denied, in whole or in part, you must receive a written explanation of the reason for the denial.  You have the right to have the Plan review and reconsider your claim.  Under ERISA, there are steps you can take to enforce the above rights.  For instance, if you request materials from the Plan and do not receive them within 30 days, you may file suit in a federal court.  In such a case, the court may require the Employer to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the Employer.  If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or federal court.  If it should happen that Plan fiduciaries misuse the Plan’s money, or if you are discriminated against for asserting your rights, you may file suit in a federal court.  The court will decide who should pay court costs and legal fees.  If you are successful, the court may order the person you have sued to pay these costs and fees.  If you lose, the court may order you to pay these costs and fees.  If you have any questions about your Plan, you should contact the Employer.  If you have any questions about this statement or about your rights under ERISA, you should contact the nearest office of the Pension and Welfare Benefits Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Pension and Welfare Benefits Administration, U.S. Department of Labor, 200 Constitution Avenue, N.W.,

Washington, D.C. 20210.  You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Pension and Welfare Benefits Administration.
