|Re:   |  | Separation and Release Agreement

As we discussed, a decision for a change in leadership in the Legal Department has been reached and as such your
employment with the company is being terminated. By mutual agreement, you and I have agreed that your position will be transitioned out and as such, your employment will terminate effective April 4, 2008. It is expected that during your
transition period you will continue to faithfully conduct yourself in a professional manner and complete all agreed upon tasks by March 31, 2008.

You will be paid your base pay through April 4, 2008, and for any unused, accrued vacation. You are entitled
to your earned Q1 MIP bonus which will be paid out in accordance with the normal payroll on April 30th. Your medical benefits will be paid
through April 30, 2008. You will be notified of your rights to continue benefits for up to eighteen (18) months under COBRA. You have ninety (90) days from your termination date to exercise any vested stock options. You will also be
provided an outplacement program to assist you in your transition to new employment. You must begin your outplacement program within 60 days from your termination date. After that date, the outplacement services will no longer be available to you.

In addition, if you sign this Separation and Release Agreement, you will receive a lump sum payment of $367,000 severance pay calculated on your base
salary less required deductions, including deductions for applicable state and federal taxes. This lump sum payment will be made on April 4, 2008. The company will also continue your medical, dental, and vision (as applicable) by paying your
COBRA premiums through March 31, 2009. Following IRS rules, these costs will be added as income on your W2. If you become employed within this period and are entitled to equal or better benefits with your new employer, you agree to notify the
company to terminate the continuation of COBRA benefits. You can continue your COBRA coverage at your own expense per federal guidelines. In addition, your stock options and/or restricted stock awards shall continue to vest during the twelve
(12) month period commencing April 4, 2008. You will have ninety (90) days from April 3, 2009 to exercise any vested stock options. In the event that an Event is announced (as defined in the 2002 Stock Incentive Plan)
prior to April 3, 2009, and subsequently closes, your shares shall immediately become fully vested and nonforfeitable effective as of immediately prior to and contingent upon consummation of the Event. In addition, you may keep your laptop,
Sprint card and cell phone (services after April 4, 2008 shall be at your expense).

Pursuant to your Employment Agreement you agreed to preserve as
confidential all trade secrets, confidential knowledge, data or other proprietary information relating to products, processes, know-how, designs, formulas, developmental or experimental work, computer programs, data bases, other original works of
authorship, customer lists, business plans, financial information or other subject matter pertaining to any business of Secure Computing or any of its employees, clients, consultants or licensees. Moreover, you agree for a period of twelve
(12) months after your termination not to, directly or indirectly through others, solicit, recruit, or encourage any Secure Computing employees to leave their employment.

Other than form documents you created throughout your employment with the Company, please do not keep in your possession, recreate or deliver to anyone else any and all devices, records, data, notes, reports,
proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, other documents or property, or reproductions of any aforementioned items developed by you during the course of your employment with Secure
Computing or otherwise belonging to Secure.
