Dendy and I are very pleased to confirm your promotion to Senior Vice President,
Program and Information Services effective January 7, 2003. In this capacity,
you continue to report to me. In line with your new responsibilities, we have
decided to increase your base salary to $190,000 per year effective
retroactively to the effective date. With your incentive compensation plan of
$100,000, your new annual target compensation is $290,000 ($190,000 base,
$100,000 incentive).

We are pleased to advise you that the Board has approved the issuance to you of
new options for an additional 30,000 shares of GTSI Common Stock. The Grant Date
for these options is January 28, 2003. Your exercise price will be equal to the
closing price of the Company's Common Stock on the Grant Date. Your options will
vest and be exercisable, cumulatively, in four equal annual installments with
the first installment vesting on the first anniversary of the Grant Date. They
will be subject to the terms and provisions of a Stock Option Agreement which we
will be providing you shortly. Your options will expire, to the extent not
previously exercised, upon the earlier of ten years from the date of initial
vesting or one month after you cease to be a GTSI employee.

Bridget Atkinson will follow up with you as needed if you have any questions
about your new compensation. As always, we ask that you keep confidential all
matters associated with your compensation. Please sign below on the enclosed
