Dear Stockholder:

         Allen C. Outlaw has recently resigned from the Board of Directors of
On-Site Sourcing, Inc. (the "Company") and as the Company's director of sales &
marketing to pursue other career interests. The Board has chosen Michael D.
Brant to replace Mr. Outlaw as one of its nominees to the Board to be voted upon
at the Company's 2001 Annual Meeting of Stockholders to be held June 4, 2001.

         Mr. Brant, 53 years old, has been the CEO and President of
iDoxSolutions, Inc., a digital asset management provider headquartered in Chevy
Chase, Maryland, since December of 2000. Prior to that time, Mr. Brant was the
CEO and President of DoxSys, Inc., a company he founded in 1993 to provide
imaging and workflow products and services. Before 1993, Mr. Brant spent 21
years at Xerox Corporation in various sales and marketing positions, concluding
his tenure as Vice President of Xerox's custom systems division. Mr. Brant is a
graduate of the University of Maryland with a BS in Marketing.

         The Board of Directors unanimously recommends that you vote for the
election of Michael D. Brant as a director. As we advised you in our proxy
statement dated April 30, 2001, the proxy you submit can be used by to vote for
any replacement nominee selected by the Board. Accordingly, if you have already
mailed in your proxy or mail one in now, the proxy will be used to vote for Mr.
Brant unless you revoke your proxy or specifically indicate on your proxy that
you withhold your vote for Mr. Brant. IF YOU HAVE ALREADY MAILED IN YOUR PROXY
AND WISH TO VOTE FOR MR. BRANT, YOU DO NOT NEED TO DO ANYTHING FURTHER AT THIS
TIME.

                                                Sincerely,

                                                /s/ Christopher J. Weiler
