      On March 17, 1998, Osage Systems Group, Inc. (the "Company") acquired in

Solsource Computers, Inc. and the Shareholders of Solsource Computers, Inc.
dated February 27, 1998 (the "Solsource Merger Agreement"). Upon closing, the

of Solsource in exchange for $1.1 million; payable $200,000 in cash and $900,000

consideration included earn-out incentive shares to be issued if Solsource

J. Vahalla, owned over 98% of the outstanding capital stock of Solsource;
accordingly, a proportionate amount of the merger consideration was paid to Mr.

of Jones from its sole shareholder Hugh V. Jones for a purchase price of
$1,975,000; payable $395,000 in cash and $1.58 million in preferred stock which
converts into common stock during the next four quarters at a conversion rate
equal to the lower of $6.87 or a 33% premium over the average closing price of
the Company's common stock for the ten (10) trading days prior to each date of
conversion. The merger consideration also included additional earn-out incentive
