Accordingly, Executive shall be entitled to receive the following pursuant to Section 6 of the Employment Agreement: (a) a single lump sum payment equal to 100% of his current Base Salary (which Executive acknowledges to be $275,000.00), pursuant to Section 6(c) of the Employment Agreement; (b) a single lump sum payment in an amount equal to 100% of Executive’s target annual incentive compensation under all Incentive Compensation Plans (annual and quarterly) of the Company in which Executive participated in 2008 (which

The payments called for by clauses (a) and (b) will be paid within three (3) days of the Separation Date.

In lieu of any amounts that might become due in the future pursuant to Section 6(d)(2) or (3) of the Employment Agreement, Executive shall receive a single lump sum payment in an amount equal to $29,301.37. This payment will be made within three days of the Effective Date defined in Section 7 of this Agreement.

All amounts referred to in this Agreement are gross amounts. The Company will deduct required and authorized withholdings.

Under no circumstances may the time or schedule of any payment made or benefit provided pursuant to this Agreement or the Employment Agreement be accelerated or subject to a further deferral except as otherwise permitted or required pursuant to regulations and other guidance issued pursuant to Section 409A of the Internal Revenue Code (the “Code”) or applicable regulations.

5. Release, Representations and Acknowledgments. In exchange for the consideration provided pursuant to this Agreement, including but not limited to the outplacement assistance provided pursuant to Section 4 and the payment provided by the second paragraph of Section 3 (the payment in lieu of the amounts that might become due in the future pursuant to Sections 6(d)(2) and (3) of the Employment Agreement), Executive agrees as follows:

(a) Executive understands and agrees that whenever the term “Insight” is used in this Agreement, it refers to the Company, its corporate parents and its subsidiaries and affiliates, and the officers, directors, shareholders, agents, predecessors, successors, assigns, and current and past employees of each and all of the foregoing (“Insight”). Executive, for himself and, as applicable, his respective agents, attorneys, successors, and assigns, hereby fully, forever, irrevocably, and unconditionally releases Insight from any and all claims, charges, complaints, liabilities, and obligations of any nature whatsoever, which he may have against Insight, whether now known or unknown, and whether asserted or unasserted, arising from any event or omission occurring prior to execution of this Agreement. Without limiting the foregoing, this release includes any and all claims arising out of or which could arise out of the employment relationship between Executive and Insight and the termination of that employment, including but not limited to: (i) any and all claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, Section 1981 of the Civil Rights Act of 1866, the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act of 1990, the Equal Pay Act, the

Family and Medical Leave Act, the Sarbanes-Oxley Act of 2002, the Employee Retirement Income Security Act of 1974 (“ERISA”), the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Worker Adjustment and Retraining Notification Act, the Arizona Civil Rights Act, state and local civil rights laws, Arizona wage payment laws and any similar laws in other states; (ii) any and all Executive Orders (governing fair employment practices) which may be applicable to Insight; (iii) wrongful termination; or (iv) any other provision or theory of law. This release may be pled as a complete bar and defense to any claim brought by Executive with respect to the matters released in this Agreement. This release does not waive claims that arise after the date this Agreement is signed. This release also does not waive any claims that Executive may have to vested benefits due pursuant to any employee benefit plan (as that term is defined in ERISA) of the Company or any affiliate, any amounts due pursuant to the Direct Alliance Corporation 2000 Long-Term Incentive Plan, or any rights Executive may have that arise out of an award made to Executive under any equity compensation program of the Company.

(b) Executive acknowledges and agrees that the consideration he is receiving under this Agreement is sufficient consideration to support the release of all entities identified in this Section 5.

(c) Executive acknowledges and agrees that he is not aware of any facts or circumstances that could be the basis for a valid claim or charge of discrimination or harassment against Insight.

(d) Executive acknowledges and agrees that he is waiving his right to file a lawsuit under the Age Discrimination in Employment Act.

(e) Executive acknowledges and agrees that he has been granted any FMLA leave to which he was entitled and has not been subjected to any discrimination or retaliation for using FMLA leave.

Executive has been advised and is hereby advised in writing to consult with an attorney prior to signing this Agreement and that he has twenty-one (21) days from the date he is presented with this Agreement to consider this Agreement. If Executive executes this Agreement before the expiration of twenty-one (21) days, he acknowledges that he has done so for the purpose of expediting the resolution of this matter, that he has had sufficient time to consider this Agreement and that he has expressly and voluntarily waived his right to take twenty-one (21) days to consider this Agreement. To accept the offer in this Agreement, Executive must sign and return the Agreement to the Company, by the twenty-second (22nd) day following the date of presentation hereof, at the following address: Insight Enterprises, Inc., 1305 West Auto Drive, Tempe, Arizona, 85284, Attention: General Counsel.

Executive agrees that if he elects to revoke this Agreement, he will notify the General Counsel of the Company (at the above address) in writing on or before the expiration of the revocation period. Receipt by the Company of proper and timely notice of revocation from Executive cancels and voids this Agreement. Provided that Executive does not provide a timely notice of revocation, this Agreement will become effective on the calendar day immediately following expiration of the revocation period (the “Effective Date”).

8. Return of Company Property. Executive represents that he has made a diligent search and has already returned to the Company all Insight documents (in electronic, paper or any other form as well as all copies thereof) and other Insight property that he has had in his possession at any time, including, but not limited to, Insight files, notes, drawings, records, business plans and forecasts, financial information, specifications, computer-recorded information, tangible property including, but not limited to, entry cards, identification badges and keys, and any materials of any kind that contain or embody any proprietary or confidential information of Insight.
