Company, together with shares of Company Preference Stock which may be acquired
after the date hereof by such Stockholder, including shares of Company
Preference Stock issuable upon the exercise of Options (as the same may be
adjusted as aforesaid), being collectively referred to herein as the "Preference
Shares" and, together with the Common Shares, the "Shares"; and

          WHEREAS, as a condition to their willingness to enter into the Merger
Agreement, Parent and Sub have requested that the Stockholders enter into this
Agreement;


          NOW, THEREFORE, to induce Parent and Sub to enter into, and in
consideration of their entering into, the Merger Agreement, and in consideration
of the premises and the representations, warranties and agreements contained
herein, the parties agree as follows:

          1.   Purchase and Sale of Shares.
               ----------------------------

          (a)  Each Stockholder hereby severally and not jointly agrees that it
     shall tender its Shares into the Offer and that it shall not withdraw any
     Shares so tendered (it being understood that the obligation contained in
     this sentence is unconditional, subject to Section 8).  In addition to, and
     not in limitation of the foregoing obligation, each Stockholder hereby
     severally and not jointly agrees to sell to Sub, and Sub hereby agrees to
     purchase, all such Stockholder's Common Shares at a price per Common Share
     equal to $5.50, or such higher price per share of Company Common Stock as
     may be offered by Sub in the Offer, and all such Stockholder's Preference
     Shares at a price per Preference Share equal to $20, or such higher price
     per share of Company Preference Stock as may be offered by Sub in the
     Offer.  Sub's obligation to purchase is subject to the following conditions
     (which may be waived in the sole discretion of Sub): (a) Sub having
     accepted shares of Company Common Stock and Company Preference Stock for
     payment under the Offer or (b) if the Offer has been terminated for failure
     to satisfy the Minimum Condition (as defined in Exhibit A to the Merger
     Agreement), (i) all conditions to the Offer set forth in Exhibit A to the
     Merger Agreement (other than the Minimum Condition) having been satisfied
     and (ii) including all shares of Company Common Stock and Company
     Preference Stock tendered and not withdrawn at the time of termination of
     the Offer and all Shares to

 
                                                                               3

     be purchased pursuant to this Agreement, the Minimum Condition would have
     been satisfied.  Notwithstanding the foregoing, no Stockholder shall be
     obligated to sell such Stockholder's Shares after the scheduled final
     expiration time of the Offer unless (i) the Minimum Condition was not
     satisfied, (ii) such Stockholder did not tender such Stockholder's Shares
     into the Offer or withdrew such Shares and (iii) including all shares of
     Company Common Stock and Company Preference Stock tendered and not
     withdrawn at the time of termination of the Offer and all Shares to be
     purchased pursuant to this Agreement, the Minimum Condition would have been
     satisfied.  Each Stockholder may tender such Stockholder's Shares into the
     Offer and the purchase of such Shares pursuant to the Offer shall satisfy
     such Stockholder's obligation to sell such Shares and Sub's obligation to
     purchase such Shares under this Agreement.  Subject to satisfaction or
     waiver of the conditions set forth in the third sentence of this paragraph,
     Sub shall, no later that three days in advance of such closing date,
     specify the place, time and date (which shall not precede the final
     expiration or termination of the Offer) for the closing of the purchase by
     Sub of such Stockholder's Shares.

     or security interest of any kind or nature whatsoever (a "Lien") upon any
     of the properties or assets of the Stockholder under, any of the terms,
     conditions or provisions of any note, bond, mortgage, indenture, lease,
     license, permit, concession, franchise, contract, agreement or other
     instrument or obligation (a "Contract") to which the Stockholder is a party
     or by which the Stockholder or any of the Stockholder's properties or
     assets, including the Stockholder's Shares, may be bound or (iii) violate
     any judgment, order, writ, preliminary or permanent injunction or decree
     (an "Order") or any statute, law, ordinance, rule or regulation of any

     Preference Stock issuable upon the exercise of Options.

          (c)  Brokers.  No broker, investment banker, financial advisor or

     other person is entitled to any broker's, finder's, financial advisor's or
     other similar fee or commission in connection with the transactions

     terms.

          (b)  Securities Act.  The Shares will be acquired in compliance with,
               ---------------                                                 
     and Sub will not offer to sell or otherwise dispose of any Shares so
     acquired by it in violation of any of, the Securities Exchange Act of 1934,

not jointly agrees as follows:

          (a)  The Stockholder shall not, except as contemplated by the terms of
     this Agreement, (i) sell, transfer, pledge, assign or otherwise dispose of,

     or may reasonably be expected to lead to, any takeover proposal (as defined
     in the Merger Agreement) or (ii) participate in any discussions or
     negotiations regarding any takeover proposal.  Without limiting the

cause to be done by virtue hereof.  Such irrevocable proxy is executed and
intended to be irrevocable in accordance with the provisions of Section 41 of

further transfers, assignments, endorsements, consents and other instruments as
Parent or Sub may reasonably request for the purpose of effectively carrying out
the transactions contemplated by this Agreement and to vest the power to vote

binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and assigns.  Each Stockholder agrees

 
                                                                               8

the later of (i) any other termination of the Merger Agreement or (ii) the
expiration of the Offer at any scheduled final expiration time without the
Minimum Condition being satisfied (provided that the failure to satisfy the

this Agreement) and (c) the date that Parent or Sub shall have purchased and
paid for the Stockholders' Shares pursuant to Section 1.  As soon as practicable
following any termination of this Agreement in accordance with the terms hereof,

to the Stockholders.
