announcement of the terms of this Agreement, but in no event later than two
business days after such public announcement. The Offer shall expire and

Offer (the "Expiration Date"); provided, however, that the Purchaser shall have
the right to extend the Expiration Date up to ten (10) additional business days
in order to satisfy any of the conditions set forth in Annex I hereto other than

Annex I hereto shall have occurred or be existing, no later than (2) two

Purchaser will extend the Offer from time to time, in each case, for the
shortest time period that it reasonably believes is necessary for the
consummation of the Offer. Each of the parties hereto shall use its reasonable
best efforts to cause all conditions precedent set forth in

Certificates and other documents in its possession relating to the transactions
described in this Agreement, and the Paying Agent's duties shall terminate.

Section 3.02 shall look only to the Surviving Corporation for payment of the
Merger Consideration in respect thereof (subject to applicable abandoned
property, escheat and similar laws), in each case, without interest or dividends
thereon.

          (d) None of Parent, the Purchaser, the Surviving Corporation or the
Paying Agent shall be liable to any person in respect of any Common Shares (or
dividends or distributions with respect thereto) or cash deposited by Parent or
the Purchaser with the Paying Agent that is delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.  If any
Certificates shall not have been surrendered prior to seven years after the
Effective Time (or immediately prior to such earlier date on which any cash
would otherwise escheat to or become the property of any Governmental Entity),
any such cash in respect of such Certificate shall, to the extent permitted by
applicable law become the property of Parent, free and clear of all claims or
interest of any person previously entitled thereto.

Parent, the Purchaser or the Paying Agent are required to deduct and withhold
with respect to such payment or issuance under the Code, or any provision of
state, local or foreign tax law.  To the extent that amounts are so withheld,
such withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holders of Common Shares in respect of which such
deduction and withholding was made.

          (f) All cash issued upon surrender of Certificates in accordance with
the terms hereof shall be deemed to have been issued in full satisfaction of all
rights pertaining to such Common Shares formerly represented thereby.  After the
Effective Time, there shall be no transfers on the stock transfer books of the
Surviving Corporation of any Common Shares which were outstanding immediately
prior to the Effective Time.  If, after the Effective Time, Certificates
formerly representing Common Shares are presented to the Surviving Corporation
or the Paying Agent, they shall be surrendered and canceled in return for the
payment of the aggregate Merger Consideration relating thereto, as provided in
this Article III, subject to applicable law in the case of Dissenting Shares.

Company after the date of this Agreement and which does not violate any
Standstill Agreement if and so long as the Board after consultation with its
counsel determines in good faith that failing to consider and cooperate with
such other party regarding such Competing Transaction would constitute a breach
of the fiduciary duties of the Board to the Company's stockholders under
applicable law, and, provided further that  in no event does the term "Competing
                     -------- -------

                                      -35-

 
Company shall and shall use its reasonable best efforts to cause its
Subsidiaries, directors, officers, employees, agents and representatives
immediately to cease all existing activities, discussions and negotiations with
any parties conducted heretofore with respect to any Competing Transaction. The
Company agrees that neither the Board of Directors nor any committee thereof

(A) withdraw or modify, or propose publicly to withdraw or modify, in a manner
adverse to Parent or the Purchase, the Board Recommendation, or (B) approve or
recommend, or propose publicly to approve or recommend, any Competing
Transaction. The foregoing notwithstanding, in the event that prior to the
purchase of Common Shares by the Purchaser pursuant to the Offer the Board of
Directors after consultation with its counsel determines in good faith that
failure to do so will result in breach of the fiduciary duties of the Board to
the Company's stockholders under applicable law, the Board of Directors may
(subject to this and the following sentences) withdraw or modify the Board
Recommendation, provided that it gives Parent three days' prior written notice
of its intention to do so. Any such withdrawal or modification of the Board
Recommendation shall not change the approval of the Board of Directors for
purposes of causing any state takeover statute or other state law to be
inapplicable to the transactions contemplated hereby, including the Offer, the
Merger or the Tender Commitments. The Company shall immediately advise Parent in
writing of the receipt, directly or indirectly, of any inquiries, discussions,
negotiations, or proposals relating to a Competing Transaction, which becomes
known to the Board during the tent of this Agreement. The Company shall keep
Parent fully apprised of the status and terms of any proposal relating to a
Competing Transaction on a current basis.

          (b) If, prior to the purchase of Common Shares by the Purchaser
pursuant to the Offer, the Board after consultation with its financial and legal
advisors determines in good faith that any written proposal from a third party
for a Competing Transaction received after the date hereof that was not
solicited by the Company or any of its Subsidiaries or affiliates in violation
of this Agreement (and that does not violate or breach any Standstill Agreement
executed by such party with respect to the Company prior to the date of this
Agreement) is more favorable to the stockholders of the Company from a financial
point of view than the transactions contemplated by this Agreement (including
any adjustment to the terms and conditions of such transaction proposed in
writing by the Company in response to such Competing Transaction) and is in the
best interest of the stockholders of the Company, the Company may terminate this
Agreement at any time prior to the Offer Purchase Closing and enter into a
letter of intent, agreement-in-principle, acquisition agreement or other similar
agreement (each, an "Acquisition Agreement") with respect to such Competing
Transaction provided that, the Company provides written notice of such
termination to Parent at least three full business days prior to the
effectiveness of such termination and, the Company delivers to Parent within
five business days following such termination (A) by check or wire transfer of
same day funds, (i) an amount equal to Parents Costs (as defined in Section
8.02) as the same may have been estimated by Parent in good faith prior to the
date of such delivery (subject to an adjustment payment between the parties upon
Parent's definitive determination of such costs), but in any event not to exceed
$10,000,000, and (ii) the amount of the Termination Fee as provided in Section
8.02 and (13) a written acknowledgment from the Company and the other party to
the Competing Transaction that the Company and such other party have irrevocably
waived any right to contest such payments.

          SECTION 6.10   Cooperation for Financing.  The Company agrees that,
                         -------------------------                           
during the term of this Agreement it shall provide reasonable cooperation to the
Purchaser to facilitate the Purchaser's efforts to obtain the financing
contemplated by the Commitment Letters (including assisting the Purchaser in
obtaining required consents) and provide all information reasonably requested by
the Purchaser in connection with the Purchaser's efforts to satisfy the Offer
Financing Condition.

          SECTION 6.11   Tender Commitments.  The Company shall cause each of
                         ------------------                                  
the Stockholders to execute a Tender Commitment.  The Company shall not permit
the amendment, modification, release under or otherwise lessen the obligations
of the Stockholders under the Tender Commitments.  The Company agrees to enforce
fully and promptly all provisions of the Tender Commitments, including, without
limitation. seeking specific performance of (or other equitable and legal
remedies with respect to) each Stockholder's obligations under its Tender
Commitment.

Company, its equity securities and its assets; or

          (e) On or after the date of the Merger Agreement any Material Adverse
Effect on the Company shall I have occurred or be occurring; or

          (f) The representations and warranties set forth in Section 4.03 or

terms. Pursuant to the Merger Agreement, Parent and Purchaser have agreed to use
their respective reasonable best efforts to obtain financing for the Offer and
to cause all other conditions to be fulfilled.

rise to any such conditions and may be waived by Parent or the Purchaser in
whole or in part at any time and from time to time in their reasonable
discretion, in each case, subject to the terms of the Merger Agreement.  The
failure by Parent or the Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such Right shall
