                                    RECITALS

          A.   Concurrently with the execution of this Agreement Public and the
Company have entered into an Agreement and Plan of Merger, dated as of August
28, 2001 (the "Merger Agreement"), which provides for the merger (the "Merger")
of a wholly owned subsidiary of Public with and into the Company.

          B.   Pursuant to the Merger, each share of common stock, par value

Agreement) (including all shares of Series A-1 Convertible Participating
Preferred Stock, par value $.01 per share, of the Company and Series A-2
Convertible Participating Preferred Stock, par value $.01 per share, of the
Company which shall have been converted into Company Common Stock immediately
prior to the Effective Time in accordance with Section 5(b)(ii) of the

Agreement, be converted into shares of common stock, par value $0.01 per share,
of Public (the "Public Common Stock") on and subject to the terms and conditions
set forth in the Merger Agreement.

          C.   Stockholder is the record and beneficial owner (as defined in

convertible into, or exercisable or exchangeable for, shares of Company Common
Stock, as set forth on the signature page of this Agreement (collectively, the
"Shares").

          D.   In consideration of the execution of the Merger Agreement by
Public, Stockholder desires to restrict the transfer or disposition of any of
the Shares, or any other shares of capital stock of the Company acquired by
Stockholder hereafter and prior to the Expiration Date (as defined herein), and
desires to vote the Shares and any other such shares of capital stock of the
Company so as to facilitate the consummation of the Merger.

          NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained herein, and intending to be
legally bound hereby, the parties hereto hereby agree as follows:

          1.   Agreement to Retain Shares.
               --------------------------

               (a)  The Stockholder irrevocably agrees, during the period
beginning on the date hereof and ending on the earlier of (i) the Effective Time
(as defined in the Merger Agreement) or (ii) the date of termination of the
Merger Agreement in accordance with Article IX thereof (such earlier date, the
"Expiration Date"), not to, directly or indirectly (including,
<PAGE>

without limitation, through the disposition or transfer of any equity interest
in another person), transfer, assign, sell, grant any option with respect to,
exchange, pledge or otherwise dispose of or encumber (collectively, "Transfer"),
or enter into any agreement or understanding with respect to the foregoing, any
Shares or any New Shares (as defined below), or to discuss, negotiate, or make
any offer or agreement relating thereto, other than to or with Public, in each
case without the prior written consent of Public or grant any proxies or enter
into any voting trust or other agreement or arrangement with respect to the
voting of any Shares or New Shares.

          (b) The Stockholder agrees that any shares of capital stock of the
Company that the Stockholder purchases or with respect to which the Stockholder
otherwise acquires beneficial ownership after the date of this Agreement and
prior to the Expiration Date, including, without limitation, shares issued upon
the conversion, exercise or exchange, as the case may be, of all securities held
by the Stockholder which are convertible into, or exercisable or exchangeable
for, shares of capital stock of the Company ("New Shares"), shall be subject to
the terms and conditions of this Agreement to the same extent as if they
constituted the Shares.

     2.   Agreement to Vote Shares.  Until the Expiration Date, at any meeting
          ------------------------
of stockholders of the Company called with respect to any of the following, and
at every adjournment or postponement thereof, and on every action or approval by
written consent of stockholders of the Company with respect to any of the
following, the Stockholder shall vote or cause to be voted its Shares and any
New Shares (to the extent any such New Shares may be voted):

          (a) in favor of the adoption of the Merger Agreement and each of the
transactions contemplated thereby;

          (b) against (i) any proposal made in opposition to or in competition
with the Merger and the Merger Agreement and the transactions contemplated by
the Merger Agreement, or (ii) any merger, reorganization, consolidation, share
exchange, business combination, sale of assets, recapitalization, liquidation,
winding up, extraordinary dividend or distribution, significant share repurchase
or other similar transaction with or involving the Company and any party other
than Public.

          (c) against any action that is intended, or could reasonably be
expected to, impede, frustrate, interfere with, impair, delay or prevent
consummation of the transactions contemplated by the Merger or any of the other
transactions contemplated by the Merger Agreement.

     The obligation of the Stockholder specified in this Section 2 shall apply
regardless of whether the Company recommends to its stockholders the approval
and adoption of the Merger Agreement and the Merger.  Prior to the Expiration
Date, the Stockholder shall not enter into any agreement or understanding with
any Person to vote or give instructions in any manner inconsistent with this
Section 2.  For purposes of this Agreement, the term "Person" shall mean a
natural person, partnership, corporation, limited liability company, business
trust, joint stock company, trust, unincorporated association, joint venture,
governmental entity or other or organization.

          -------------

          (a)  Severability. If any term, provision, covenant or restriction of
               ------------
this Agreement is held by a court of competent jurisdiction to be invalid, void
