sold to the Investor, and the Investor purchased from the Company, 500 shares of
the Company’s 7% Series I Convertible Preferred Stock, par value $1.00 per share
(the “Original Preferred Stock”), which are convertible into shares of the
Company’s common stock, par value $.10 per share (the “Common Stock”), and
warrants to purchase 203,390 shares of Common Stock (the “Original Warrants”).

     B.     In connection with the Original Purchase Agreement, the Company
filed a Certificate of Designations with the Secretary of State of Delaware
containing the rights, preferences and privileges of the Original Preferred

Stock, the Original Warrants and 129,470 shares of Common Stock (collectively,
the “Existing Investor Securities”).

     D.     The Investor and the Company desire that the Investor exchange all
of the Existing Investor Securities for a combination of cash, shares of a newly
issued non-convertible preferred stock of the Company and shares of Common Stock
(the “Exchange”) upon the terms and subject to the conditions set forth in an
exchange agreement between the Company and the Investor of even date herewith
(the “Exchange Agreement”).

     E.     The Exchange Agreement contemplates that the Company and the
Investor will execute and deliver this Release as a condition to the closing of
the Exchange and this Release is a material inducement to the parties entering
into the Exchange Agreement.

     NOW, THEREFORE, in consideration of the Exchange and the mutual covenants
contained in this Agreement, and for other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the Company and the
Investor agree as follows:

Releasors ever had, now have, or hereafter can, shall, or may have, for, upon or
by reason of any matter, cause or thing whatsoever from the beginning of the
world to the date of this Release, except for claims under the Exchange

whom enforcement of any such waiver is sought.

     5.     Severability. In case any one or more of the provisions of this
Release shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Release shall not
in any way be affected or impaired thereby and the parties will attempt to agree
upon a valid and enforceable provision which shall be a reasonable substitute
therefor, and upon so agreeing, shall incorporate such substitute provision in

     7.     Execution. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.
