     for corporate, operating or executive officers or other management 
     employees of the Company, You shall be eligible to fully participate in 
     each such plan or benefit program.

     provide health, medical, disability and term life insurance to You and 
     your family in accordance with any group plan which it now maintains or 
     which may hereafter be established by the Company.  If the Company does 
     not maintain any group plan providing all of the coverages described 
     above for which You and your family are eligible, the Company shall 
     reimburse You, upon request, for Your insurance policy payments for any 
     such coverages under policies held by You on April 1, 1998 (and under 
     any replacement 

                                       3



     policies).  In any event, the Company shall reimburse You, upon request,

     the coverages and benefits under such term life insurance policy.  The 
     $1,000,000 term life insurance coverages and payments described in this

     provided to executive officers of the Company generally.

          (f)  You shall receive not less than four (4) weeks paid vacation 
     during each twelve (12) month period of Your employment.  Such vacation 
     period may be increased from time to time and at any time by the Board 
     of Directors but shall in no event be shortened to less than the longest

     amounts to be paid to You immediately upon Your request.

     5.   STOCK OPTIONS.

          (a)  Pursuant to a Non-Qualified Stock Option Agreement dated 
     February 19, 1998 (the "Option Agreement"), You have been granted 
     options to purchase 150,000 shares of the common stock of the Company at 
     $44.75 per share (the "Option Shares") under the Earthlink Network, Inc. 
     1995 Stock Option Plan (the "Plan").  Upon your exercise of these 
     options in accordance with the Plan and Option Agreement, the Company 
     will pay to you $24.75 with respect to each share of the Option Shares 
     purchased by You.  This provision is intended to provide to You 
     additional compensation for your services tied to your purchase of the 
     Option Shares.  The $24.75 amount payable to You with respect to your 
     purchase of each Option Share is subject to equitable and proportional 
     adjustment in accordance with the adjustment and exchange mechanisms in 
     the Plan with respect to the exchange, number and pricing of the Option 
     Shares.

          (b)  Your options to purchase voting common stock of the Company 
     described in Section 5(a) of this Agreement and as granted by the 
     Company to You from time to time prior to and after the date of this 
     Agreement are hereinafter collectively called the "Stock Options."  In 
     the event a Change in Control Event occurs or the Company terminates 
     Your employment for other than "Cause" or You terminate Your employment 
     for reasons of a breach by the Company of this Agreement, all unvested 
     Stock Options 

                                       4




     (including the options for the Option Shares) shall immediately vest and 
     be fully exercisable by You.  You shall be given the maximum period 
     permitted under the Company's stock option plans to exercise Your Stock 
     Options after termination of Your employment with the Company.

          (c)  You hereby acknowledge that the Stock Options and the Option 
     Shares are and will be acquired by You for investment purposes with no 
     view to the sale or public distribution thereof.  You further represent 
     and warrant to the Company that You are aware that the Company is 
     relying upon Your investment intent expressed hereinabove, and is 
     issuing the Stock Options and the Option Shares pursuant to an exemption 
     from the registration requirements of the Securities Act of 1933, as 
     amended ("1933 Act") under Section 4(2) thereof as transactions "not 
     involving any public offering."  You agree that the transfer of the 
     Stock Options and the Option Shares to be issued may be restricted, that 
     a legend in form satisfactory to the Company may be placed on any 
     certificate representing any of the Stock Options and the Option Shares, 
     that stop-transfer orders may be placed against the transfer of any of 
     the Stock Options nor the Option Shares and that neither the Stock 
     Options nor the Option Shares will be and may not be sold or transferred 
     by You unless You shall satisfy the Company with such documentation as 
     the Company in its absolute discretion may request [which may include an 
     opinion of Your counsel acceptable to the Company] that such transfer is 
     in full compliance with the provisions of the 1933 Act, and the Rules and
     Regulations promulgated thereunder, and that such transfer will not 
     constitute or imply any violation of the 1933 Act, or any of the Rules and 
     Regulations promulgated thereunder by either the Company or You.

          (d)  If at any time or times after the date hereof, the Company 
     shall determine or be required to register any shares of its capital 
     stock or securities convertible into capital stock under the Securities 
     Act of 1933 whether in connection with a public offering of securities 
     by the Company (a "primary offering"), a public offering of securities 
     by shareholders of the Company (a "secondary offering") or both, the 
     Company will promptly give You written notice thereof.  If within 30 
     days after Your receipt of such notice You request the inclusion of some 
     or all of Your Option Shares or other shares acquired by You pursuant to 
     the Stock Options or otherwise (the "Registrable Securities"), the 
     Company will use its best efforts to effect the registration under the 
     Securities Act of all Registrable Securities which You have requested be 
     registered.  The Company shall pay all costs and expenses associated 
     with the registration of Your Registrable Securities including 
     reasonable fees of legal counsel.  In connection with any registration 
     statement in which You are participating, You agree to furnish the 
     Company with the personal information, opinion letter, indemnifications 
     and other items and materials necessary and/or proper (and that are 
     customarily and generally requested of parties with similar registration 
     rights) in connection with a registration of securities under the 
     Securities Act of 1933.  The manner and content of any such registration 
     statement and of any underwriting or other agreements related thereto, 
     shall be entirely in the control and discretion of the Company.  You 
     agree to cooperate with the Company in the preparation and filing of any 
     registration statement prepared and filed and shall make 

                                       5




     the customary agreements, representations, warranties and indemnifications 
     to the underwriters and/or the Company with respect to any Registerable 
     Shares included therein.

               (1)  For Cause immediately by the Company; or

          You.

          (b)  If the Company terminates Your employment for other than 
     "Cause" or the Company shall elect not to extend the Term at the end of 
     the first three (3) years or any yearly extension of the Term or You

               (2)  You shall receive all earned but unpaid Bonus Payments as 
          well as the Bonus Payments based on the portion of the year that 
          You were employed by the Company in the year in which You were 
          terminated; and

               (3)  The health, medical, life and disability coverages 
          afforded to You and your family by the Company (or payments in lieu 
          thereof) as set forth in Section 4(e) shall be continued for the 
          Severance Period.

          (c)  In the event that Your employment is terminated by the Company 
     due to Your death:

                                       6



               (1)  Your estate shall continue to be paid the Base Salary for 
          a period of one (1) year from the date of your death;

               (2)  Your estate shall receive all earned but unpaid Bonus

          (d)  In the event that Your employment is terminated by the Company

     the Company, the Company will have no obligations to pay You any amount 
     beyond the effective date of such termination whether as Base Salary, 
     Bonus Payment or otherwise or to provide You with any benefits arising 
     hereunder or otherwise except as required by law.

     7.   CONFIDENTIAL INFORMATION.  You acknowledge that the nature of Your 
engagement by the Company is such that You shall have access to information 
of a confidential and/or trade secret nature which has great value to the 
Company and which constitutes a substantial basis and foundation upon which 
the business of the Company is based.  Such information includes financial, 
manufacturing and marketing data, plans and methods, computer software 
program technology, i.e., process, formulas, research or development and test

treated as secret and/or confidential by the Company (the "Confidential 
Information").  The Company has and will also have access to Confidential 
Information of its clients ("Clients" means any persons for whom the Company 
performs services or from whom the Company or You obtains information). 
Confidential Information includes not only information disclosed by the 
Company or its clients to You in the course of Your employment, but also 
information developed or learned by You during the course of Your employment 
with the Company. Confidential Information is to be broadly defined.  
Confidential Information includes all information that has or could have 
commercial value or other utility in the business in which the Company or 
Clients are engaged or in which they contemplate engaging.  Confidential 
Information also includes all information of which the unauthorized 
disclosure could be detrimental to the interests of the Company or clients, 
whether or not such information is identified as Confidential Information by 
the Company or Clients.  You agree to keep all such Confidential Information 
in confidence during the term of this Agreement and at any time thereafter 
and shall not use, disclose, publish or otherwise disseminate any of such 
Confidential Information to any other person, except to the extent such 
disclosure is (i) necessary to the performance of this Agreement and in 
furtherance of the Company's best interests, 

                                       7



(ii) required by applicable law, (iii) lawfully obtainable from other 
sources, (iv) authorized in writing by the Company, (v) no longer qualifies 
as a trade secret or confidential information under applicable law, or (vi) 
necessary to enforce this Agreement.  Upon termination of Your employment 
with the Company, You shall deliver to the Company all documents, records, 
notebooks, work papers, and all similar material containing Confidential 
Information, whether prepared by You, the Company or anyone else.

     8.   INVENTIONS AND PATENTS.  Except as may be limited by Section 2870 
of the California Labor Code, all inventions, designs, improvements, patents, 
copyrights and discoveries conceived by You during the term of this Agreement 
which are useful in or directly or indirectly relate to the business of the 
Company or to any experimental work carried on by the Company, shall be the 
property of the Company. You agree to promptly and fully disclose to the 
Company all such inventions, designs, improvements, patents, copyrights and 
discoveries (whether developed individually or with other persons) and at the 
Company's expense, to take all steps necessary and reasonably required to 
assure the Company's ownership thereof and to assist the Company in 
protecting or defending the Company's proprietary rights therein.

     You acknowledge hereby receipt of written notice from the Company that 
this Agreement (to the extent it requires an assignment or offer to assign 
rights to any invention of Yours) does not apply fully to an invention which 
qualifies fully under California Labor Code Section 2870.

     9.   NON-COMPETITION.  In order to protect the Confidential Information, 
You agree that during the term of Your employment, and for a period of one 
(1) year thereafter, You will not, directly or indirectly, whether as an 
owner, partner, shareholder, agent, employee, creditor, or otherwise, 
promote, participate or engage in any activity or other business competitive 
with the Company's business in California if such activity or other business 
involves any use by You of any of the Confidential Information.

     10.  NON-SOLICITATION OF CUSTOMERS.  You agree that for a period of one 
(1) year after the termination of Your employment with the Company, You will 
not, on Your own behalf or on behalf of an other individual, association or 
entity, call on any of the customers of the Company for the purpose of 
soliciting or inducing any of such customers to acquire (or providing to any 
of such customers) any product or service provided by the Company, nor will 
You in any way, directly or indirectly, as agent or otherwise, in any other 
manner solicit, influence or encourage such customers to take away or to 
divert or direct their business away from the Company to You or to any other 
person or entity by or with which You are employed, associated, affiliated or 
otherwise related.

     11.  NONINTERFERENCE WITH EMPLOYEES.  In order to protect the 
Confidential Information, You agree that during the term hereof and for a 
period of one (1) year thereafter, You will not, directly or indirectly, 
induce or entice or hire any employee of the Company with access to or 
possession of Confidential Information, to leave such employment or cause 
anyone else to leave such employment.

     12.  EXTENSION OF PERIODS.  In the event that Your employment with the 
Company is terminated for any reason other than by You based on a breach of 
this Agreement by the 

                                       8



Company, the Company may extend the one (1) year periods described in 
Sections 9, 10 and 11 on a month-to-month basis for a period of up to an 
additional one (1) year period, upon payment to You of an amount equal to one 
twelfth (1/12) of Your Base Salary per month on the last day of each such 
month.  The Company shall give You notice of the duration of such extension, 
if any, within seven (7) days of the termination of Your employment by the 
Company.

     13.  REMEDIES.  The parties hereto agree that the services to be 
rendered by You pursuant to this Agreement, and the rights and privileges 
granted to the Company pursuant to this Agreement, are of a special, unique, 
extraordinary and intellectual character, which gives them a peculiar value, 
the loss of which cannot be reasonably or adequately compensated in damages 
in any action at law, and that a breach by You of any of the terms of this 
Agreement will cause the Company great and irreparable injury and damage.  
You hereby expressly agree that the Company shall be entitled to the remedies 
of injunction, specific performance and other equitable relief to prevent a 
breach of this Agreement by You.  This Section 13 shall not be construed as a
