                  GTSI AND BTG SIGN DEFINITIVE AGREEMENT
                   GTSI Purchases BTG's Product Division


CHANTILLY, VA (February 12, 1998) - Government Technology Services, Inc.
(GTSI) (Nasdaq:GTSI) and BTG, Inc. (Nasdaq:BTGI) today announced that they
signed the definitive agreement for and completed the sale to GTSI of
substantially all of the BTG division assets responsible for reselling
computer hardware, software, and systems to the Federal Government.  Under
the terms of the sale, GTSI provided 15,375 shares of a new series of
preferred stock, designated Series C 8% cumulative redeemable preferred
stock and $8 million in cash to BTG.  The preferred stock is nonvoting
except for the right to elect one member of the GTSI board.  Under the
terms of the sale, BTG also has the right to nominate a second director
subject to GTSI's consent. 

     GTSI will seek shareholder approval at its upcoming annual meeting for
conversion of the preferred stock to three million shares of common stock.
If shareholder approval is obtained, the preferred stock will automatically
convert to common stock. If shareholder approval is not obtained,
dividends, payable annually in cash or preferred stock at GTSI's option,
will begin to accrue on the preferred stock at an annual rate of 8% and the
preferred stock will become redeemable by GTSI at an initial redemption
price equal to the liquidation preference of $1,000 per share (or
$15,375,000) in the aggregate) plus accrued but unpaid dividends. If
conversion is not approved at the first shareholders meeting, GTSI has
agreed to seek approval at the next shareholders' meeting.

     Dendy Young, President and CEO of GTSI, stated, "This transaction will
cement GTSI's position as a leading federal channel information technology
reseller and enable the company to better compete in the federal
information technology segment. We are focusing on the vital issue of
successfully combining the workforces of GTSI and the BTG division to
better serve our customers." Mr. Young added, "I welcome Dr. Bersoff to our
Board."
