        Re:     Clarus Corporation
                ------------------

Dear Ms. McBrayer:

        We are in receipt of your letter of April 5, 2002, and have forwarded it
to Mr. Kanders. Please be advised that Mr. Kanders welcomes the opportunity to
meet with Clarus' Chairman of the Board and Chief Executive Officer and the
independent members of the Board of Directors.

        Mr. Kanders' agenda is simple. He is looking to reverse Clarus' trend of
quarter upon quarter of disappointing results and loss of significant
shareholder value. To that end, he and his nominees to Clarus' Board are
prepared to explore all viable alternatives to put an end to Clarus' erosion in
shareholder value. Each of Mr. Kanders and his proposed nominees to Clarus'
Board (each of whose nominations were provided to Clarus in Mr. Kanders' initial
letter of March 20, 2002, which was submitted in a timely fashion in accordance
with Clarus' bylaws for inclusion in this year's annual meeting of shareholders)
is prepared to provide Clarus with a statement agreeing to be named in Clarus'
proxy statement and to serve on Clarus' Board if elected by the shareholders.

        Mr. Kanders' and his nominees' record of running public companies and
multiplying shareholder value is self-evident, and he is prepared to discuss
their respective qualifications. We appreciate your reminder of Mr. Kanders'
obligations under the federal securities laws. Please be assured that Mr.
Kanders, through his own experience and with the advice of counsel, including
special Delaware counsel, will fully comply with his legal obligations.

        Please call me to schedule a meeting between Mr. Kanders and the Clarus
representatives identified above. You should be aware of Mr. Kanders' resolve in
putting forth his own slate of directors for nomination if Clarus does not
include his nominees for election at this year's annual meeting of shareholders,
together with any other proposals they may deem appropriate under the
circumstances. Similarly, any attempt by Clarus to increase the size of its
Board or to otherwise circumvent the nomination of Mr. Kanders and his
colleagues will be viewed as not being in the best interests of the
shareholders, and Mr. Kanders reserves the right to, among other things, name
additional nominees in such event.

        A prompt meeting of Mr. Kanders and the named Clarus representatives is
therefore urged and, in Mr. Kanders' view, in the best interests of all
shareholders.

        I look forward to hearing from you.

                                           Very truly yours,

                                           /s/ Aris Haigian
