C. Executive and the Company each desires to resolve amicably, fully and finally all matters between them, including, but in no way limited to, those matters relating to the employment relationship between them and the termination of that relationship.

NOW THEREFORE, in consideration of the recitals above and the mutual promises and obligations contained herein, and other good and valuable consideration, the receipt and sufficiency of which are expressly acknowledged, it is agreed as follows:

AGREEMENTS

In consideration of the mutual promises in this Agreement, it is agreed as follows:

1. Separation Date. The Company and Executive agree that Executive’s employment with the Company will terminate effective as of September 1, 2011 (the “Separation Date”).

2. Recitals. The parties hereby acknowledge the correctness and accuracy of the foregoing recitals.

3. Payments and Benefits. Executive shall be entitled to receive the following Severance Benefits pursuant to the Employment Agreement:

(a) Severance Payments. Executive’s termination shall be treated as a termination by the Company without Cause within the meaning of Section 6(b) of the Employment Agreement. 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 $278,100.00), pursuant to Section 6(c) of the Employment Agreement; and (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 2010 (which Executive acknowledges to be $172,500.00) in lieu of and in full satisfaction of any payments due Executive pursuant to Section 6(d)(1) of the Employment Agreement. The payments called for by clauses (a) and (b) will be paid within three (3) days of the Separation Date. The Company will pay Executive the amounts referred to in this paragraph along with any wages and accrued and untaken vacation pay through his last day of employment without regard to whether Executive executes this Agreement.

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 $115,000. This payment will be made within three days of the Effective Date defined in Section 7 of this Agreement.

(b) Health Insurance. Pursuant to Section 6(e) of the Employment Agreement, the Company also shall pay the full premium cost of life, disability, accident and group health and dental insurance benefits for Executive, at substantially the levels Executive was receiving immediately prior to Executives’s Separation Date, including any of his dependents participating in the Company’s medical, dental vision and prescription plans on the Separation Date, for a period of time expiring upon the earlier of: (1) the end of the period of twelve (12) months following the Executive’s Separation Date; or (2) the day on which Executive becomes eligible to receive any substantially similar benefits under any plan or program of any other employer or source without being required to pay any premium with respect thereto. The Company will satisfy this obligation to provide health and dental insurance benefits by either paying for or reimbursing Executive for the actual COBRA coverage (and Executive shall cooperate with the Company in all respects in securing and maintaining such benefits, including excercising all appropriate COBRA elections and complying with all terms and conditions of such coverage in a manner to minimize cost). The Company will satisfy the obligation to provide life, disability and accident insurance benefits that are not subject to COBRA continuation rules by reimbursing Executive for the cost of comparable coverage for life, disability, and accident insurance benefits. It will be the Executive’s responsibility to procure such benefits and the Company will promptly reimburse Executive for the premiums for such benefits in the specified amount upon Executive’s submission of an invoice or other acceptable proof of payment. The Company will reimburse Executive for premiums within 30 days of Executive’s submission of proof of payment. The premiums reimbursed in one taxable year will not affect the premiums eligible for reimbursement in a different taxable year. All reimbursements of premiums must be made no later than December 12, 2012. Executive many not elect to receive cash or any other benefit in leiu of the benefits described in this Section 3(b). The Company’s obligation under this paragraph will cease with respect to a particular type of coverage when and if Executive becomes eligible to receive substantially similar coverage with a successor employer.

(c) No Further Obligation. The Company’s provision of the payments and benefits described in this Section 4 shall fully satisfy its obligations to Executive.

(d) Gross Amounts. All amounts referred to in this Agreement are gross amounts. The Company will deduct required and authorized withholdings.

(e) Miscellaneous Payment Provisions. Under no circumstances may the time or schedule of any payment made or benefit provided pursuant to this Agreement or the Separation Plan be 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. Executive has not been given the right to make any election regarding the time or form of any payment due to him under this Agreement or the Separation Plan.

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 the following laws as amended 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”), COBRA, the Worker Adjustment and Retraining Notification Act, the Arizona Civil Rights Act, Arizona Employment Protection 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; (iv) any and all claims under the Employment Agreement and the Separation Plan (other than the right to the payments described in Section 4 of this Release Agreement); or (v) 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.
