     Dear Laurie:

     I am pleased to extend to you an offer as a Senior Vice President,

     Exodus' acquisition of GlobalCenter and, if you accept this offer, it would
     take effect as of that closing date (the "Closing Date").

     As an Exodus employee, you will be responsible for integrating and growing
     the business formally known as GlobalCenter as well as whatever reasonable
     duties are assigned to you consistent with your title and position. Your
     initial base salary will be $20,833.33 per month, less all applicable
     deductions, which is equivalent to a gross sum of $250,000.00 per year. You

     year anniversary with Exodus.

     You also will be eligible to participate in our health and dental insurance
     plans, 401K plan, employee stock purchase plan and other employee benefits
     established by the Company. Exodus will reimburse you for expenses
     reasonably incurred in relocating your household goods from the local area
     to Denver, Colorado, subject to Exodus' standard policies far amounts and
     documentation and shall be repaid to Exodus if your employment terminates
     for any reason prior to your one year anniversary with Exodus. In addition,
     for a period of up to twelve months commencing as of the Closing Date and
     while you are employed by Exodus, Exodus will pay, for your use, the fair
     market rental value on a residence in the Sunnyvale area and a rental car,
     not to exceed $3000.00 per month.

     We will recommend to Exodus' Board of Directors that you be granted options
     to purchase up to 100,000 shares of Exodus Communications, Inc. common
     stock. The options, if approved, customarily are granted on the first

vest, that is, become exercisable, over fifty (50) months with the first twelve
percent (12%) vesting after six (6) months of continuous employment. Thereafter,
the options will vest at a rate of 2% per month of completed service until your
employment terminates or the grant is fully vested. This option grant will be
subject to all terms of Exodus' stock option plan and stock option agreement, a
copy of which you will be required to execute as a condition of the grant.

to your former employers. Also, by accepting this offer, you represent that you
are not subject to any restrictions that prevent you from working for Exodus.

As a condition of employment, you will be required to authorize Exodus to
conduct a background investigation. This offer is contingent upon the outcome of
such an investigation as well as your ability to provide verification of your

Department of Justice.

If you accept this offer, your employment will be at-will. These means that

reason, with or without cause. This is the full and complete agreement between

well as Exodus' personnel policies and procedures, may change from time-to-time,
the "at-will" nature of your employment may only be changed in a document
signed by you and the President of the Company.

You agree that there were no promises or commitments made to you regarding your
employment with Exodus except as set forth in this letter. Except for the
Proprietary Information Agreement between you and GlobalCenter, the GlobalCenter
Management Stock Plan with the attached Non Statutory Stock Option Agreement and
as otherwise expressly provided for herein, this agreement supersedes and
replaces (i) any prior verbal or written agreements between you and Exodus and
(ii) any prior verbal or written agreements between you and GlobeCenter relating
to the subject matter hereof, including, but not limited to, any and all prior
employment agreements.

We look forward to your becoming a part of the Exodus Team. Please confirm your
