“Effective Date”), and declared a dividend distribution of one Stock Purchase
Right on each outstanding share of the Company’s Common Stock as of the record

              WHEREAS, as of the Effective Date, Black Diamond beneficially
owned 462,983 shares of the Company’s Common Stock, representing a 22.7%
ownership interest in the Company;

              WHEREAS, in reliance upon the representations and warranties made
by Black Diamond in this Agreement, and subject to the terms and conditions
hereof, the Board of Directors of the Company is willing to amend the Rights
Agreement to permit Black Diamond to own up to 585,316 shares of the Company’s
Common Stock, such amendment to be effective upon the execution of this
Agreement; and

              WHEREAS, in consideration of the Board’s undertaking to amend the
Rights Agreement, the Company and Black Diamond have agreed to enter into this
Agreement.

              NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth in
this Agreement, the parties hereto agree as follows:

              Section 1.Representations and Warranties of Black Diamond. Black
Diamond represents and warrants to the Company, as of the date hereof, as
follows:

                           (a) Black Diamond is the beneficial owner, either
directly or indirectly through one of its affiliates, of not more than 585,316
shares of Common Stock, $.01 par value, of the Company (the “Shares”).

                           (b) Except for any agreements that may exist between
Black Diamond and any affiliate under its control, Black Diamond is not a party
to any voting trust, proxy or other agreement, arrangement, undertaking or
understanding with respect to the voting of the Shares, nor does it have the
power to vote or direct the voting of any shares of the Company’s Common Stock
other than the Shares.

                           (c) All of the Shares now owned by Black Diamond were
acquired for investment purposes only and without any intention of changing,
exercising or influencing control of the Company, and there has been no change
in that intention since the date of the acquisition of such Shares. All
statements contained in Item 4 of the Schedule 13D filed by Black Diamond with
the Securities Exchange Commission on March 8, 2004, continue to be true and
correct in all respects as of the date of this Agreement.

                           (d) All shares of Company Common Stock now owned by
Black Diamond, or now owned by an affiliate of Black Diamond, are owned solely
for the account of Black Diamond or such affiliate, respectively, and neither
Black Diamond nor any of its affiliates has acted as an agent, broker, or dealer
for any unaffiliated third party with respect to the Shares. Neither Black
Diamond nor any of its affiliates has at any time acted in concert with any
third party with respect to the acquisition, disposition or voting of any shares
of the Company’s Common Stock for any purpose, including without limitation for
the purpose of changing, exercising or influencing control of or over the
Company.

              Section 2.Covenants of Black Diamond. Black Diamond covenants and
agrees as follows:

                           (a) So long as the Rights Agreement remains in
effect, Black Diamond will not, and will cause its affiliates not to, directly
or indirectly, acquire any shares of the Company’s Common Stock in addition to
the 585,316 shares of Common Stock that it owns as of the date of this
Agreement, except for any shares of Common Stock it may acquire by way of stock
split, stock dividend or other distributions (including any additional shares
acquired by participation in a rights offering or other offering by the Company)
made available generally to all holders of the Company’s Common Stock. In
addition, in the event the Company issues (other than issuances of Common Stock
pursuant to options issued prior to May 31, 2004), in one or more transactions,
Common Stock or securities convertible into Common Stock, Black Diamond and its
affiliates shall be permitted to purchase additional shares of Common Stock in
order to increase its percentage ownership (on a fully diluted basis assuming
conversion and exercise of all securities convertible or exercisable into Common
Stock) up to the percentage ownership level of the Common Stock held by Black
Diamond and its affiliates immediately prior to any such issuance of Common
Stock (a “Pre-Issuance Percentage”); provided, that Black Diamond agrees, in the
event Black Diamond or its affiliates purchases additional shares of Common
Stock pursuant to this sentence in connection with the issuance of convertible
securities by the Company, that Black Diamond agrees not to vote and to cause
its affiliates not to vote, a number of shares of Common Stock in excess of
Pre-Issuance Percentage in effect at the time of such vote. Neither Black
Diamond nor any of its affiliates shall take any action which would cause it or
such affiliate, either individually or in association with others, to become an
Acquiring Person under the Rights Agreement or for a Stock Acquisition Date to
have occurred, in each case, as such terms are defined in the Rights Agreement
in effect as of the date hereof after giving effect to the amendment.

                           (b) Black Diamond will not confer any proxy to any
third party to vote any shares of the Company’s Common Stock, and the Company
shall be entitled to disregard any proxy so granted, to the extent that the
aggregate number of shares voted by Black Diamond and the holder of such proxy
would exceed 462,983 shares of the Company’s Common Stock, provided, however,
that this covenant shall not be deemed to be violated to the extent that Black
Diamond solely grants a revocable proxy or consent to another person in response
to a public proxy or consent solicitation conducted by such person that is made
pursuant to the applicable rules and regulations under the Securities and
Exchange Act of 1934.

              Section 3. Amendment to Rights Plan. Within ten days of the date
of this Agreement, the Company will amend the Rights Agreement, effective as of
the date hereof, to revise the definition of Exempt Person to conform with the
definition set forth in Appendix A to this Agreement.

              Section 4. Governing Law. This Agreement shall be governed by
Delaware law.

Agreement to be signed as of the date first written above.
