Dear Xxxx:

This letter sets forth the substance of the separation agreement (the "Agreement") Internap Network Services Corporation (the "Company") proposes regarding your employment transition.

1.    Separation. Your last day of employment with the Company shall be July 7, 2002 (the "Separation Date").

2.    Transition Period. Effective immediately you will resign your positions as the Company's Chief Operating Officer and President, and from now through the Separation Date (the "Transition Period"), you will report to the Company's Chief Executive Officer (the "CEO") and will be expected to complete to the Company's satisfaction projects as assigned by the CEO from time to time. You will perform these duties from Austin, Texas except as may be reasonably required by the CEO to be performed in the Seattle area. If you are asked, by the Company in its sole discretion, to travel to the Seattle area, it will be arranged for mutually agreeable times and the Company will fully reimburse you for any reasonable, out-of-pocket travel related expenses, including airfare, lodging and meals that have been approved in advance by the Company in writing and comply with the Company's reimbursement policies. From January 7, 2002 through April 7, 2002 you will be paid based on an annual base salary of $348,800 stated in your Employment Agreement, less applicable withholdings and deductions, and will be entitled to continue your employee benefits, including vacation accrual. From April 8, 2002 through the Separation Date you agree to be paid at a reduced annual base salary of $174,400, less applicable withholdings and deductions, and will be entitled to continue your employee benefits, including vacation accrual.

3.    Stock Options. Your stock options will cease vesting on the Separation Date, under the terms of your written stock option agreement(s) and the applicable plan(s) governing those agreement(s). You may exercise your vested option shares pursuant to your written stock option agreement(s) and the applicable plan(s) governing those agreement(s).

4.    Expense Reimbursements. The Company will, pursuant to its regular business practice, reimburse you for expenses approved in advance by the CEO through the Separation Date, if any, that you submit within ten (10) days of the Separation Date.

5.    Return of Company Property. On or before the Separation Date, you must return to the Company all Company documents (and all copies thereof) and other Company property that you have had in your possession at any time, including, but not limited to, Company files, notes, drawings, records, business plans and forecasts, financial information, specifications, computer-recorded information, tangible property (including, but not limited to, computers), credit cards, entry cards, computer access codes, computer programs, identification badges and keys; and any materials of any kind that contain or embody any proprietary or confidential information of the Company (and all reproductions thereof).

6.    Continuing Obligations. After the Separation Date, you will have continuing obligations to the Company, including obligations not to use or disclose any confidential or proprietary information of the Company. A copy of the agreement you signed with respect to these obligations is attached to this letter as Exhibit B ("Exhibit B"). The Company agrees to amend your obligations under Section 5 of Exhibit B as follows: (a) the one (1) year period referred to in lines 5 and 6 thereof is changed to nine (9) months; and (b) the word "hosting" in line 8 thereof is replaced with "collocation."

7.    Release. In exchange for the Transition Period and other consideration under this Agreement, to which you acknowledge you would otherwise not be entitled absent this Agreement, you hereby release, acquit and forever discharge the Company, its parent and subsidiaries, and its and their officers, directors, agents, servants, employees, shareholders, attorneys, successors, assigns and affiliates, of and from any and all claims, liabilities, demands, causes of action, costs, expenses, attorneys' fees,

8.    ADEA Waiver. You acknowledge that you are knowingly and voluntarily waiving and releasing any rights you may have under the ADEA. You also acknowledge that the consideration given for the waiver and release in the preceding paragraph hereof is in addition to anything of value to which you were already entitled. You further acknowledge that you have been advised by this writing, as required by the ADEA, that: (a) your waiver and release do not apply to any rights or claims that may arise after you sign this Agreement; (b) you have the right to consult with an attorney prior to executing this Agreement; (c) you have twenty-one (21) days to consider this Agreement (although you may choose to voluntarily execute this Agreement earlier); (d) you have seven (7) days following the date you sign this Agreement to revoke the Agreement; and (e) this Agreement shall not be effective until the date upon which the revocation period has expired, which shall be the eighth (8^th) day after you sign this Agreement.

10.  Separation Date Release. As further consideration for the promises set forth in this Agreement, on the Separation Date you agree to execute, make effective and deliver to the Company the General Release and Waiver attached as Exhibit A ("the Separation Date Release"). You understand and acknowledge that failure to provide a Separation Date Release will constitute a material breach of this Agreement.

11.  Entire Agreement. This Agreement, including its exhibits, constitutes the complete, final and exclusive embodiment of the entire agreement between you and the Company with regard to the subject matter hereof. It supersedes any and all agreements entered into by and between you and the Company, including the Employment Agreement; provided, however, that Section 11 of the Employment Agreement regarding Proprietary Rights and Inventions is expressly made a part of and incorporated into this Agreement, and is not superseded. This Agreement is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein. It may not be modified except in a writing signed by a duly authorized officer of the Company.

12.  Successors and Assigns. This Agreement will bind the heirs, personal representatives, successors, assigns, executors and administrators of each party, and will inure to the benefit of each party, its heirs, successors and assigns.

13.  Applicable Law. This Agreement will be deemed to have been entered into and will be construed and enforced in accordance with the laws of the State of Washington as applied to contracts made and to be performed entirely within Washington.

14.  Severability. If a court of competent jurisdiction determines that any term or provision of this Agreement is invalid or unenforceable, in whole or in part, then the remaining terms and provisions hereof will be unimpaired. The court will then have the authority to modify or replace the invalid or unenforceable term or provision with a valid and enforceable term or provision that most accurately represents the parties' intention with respect to the invalid or unenforceable term or provision.

If this Agreement is acceptable to you, please sign below, and return the original to me.

Thank you for your efforts in support of the Company. We look forward to working with you during the Transition Period.

Sincerely yours,
Internap Network Services Corporation
