obligation of the party executing (or on whose behalf such signature is

substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

Company under this Agreement and the Company will be entitled to specific
performance of the obligations of the Purchaser hereunder with respect to the
subsequent transfer of Shares. Each of the Company and the Purchaser agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of any breach of its obligations described in the foregoing sentence and
hereby agrees to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

duly and validly existing and in good standing under the laws of the
jurisdiction of its incorporation. The Purchaser has the requisite power and
authority to enter into and to consummate the transactions contemplated hereby
and otherwise to carry out its obligations hereunder and thereunder. The
purchase of the shares of Common Stock by the Purchaser hereunder has been duly
authorized by all necessary action on the part of the Purchaser. This Agreement
has been duly executed and delivered by the Purchaser or on its behalf and
constitutes the valid and legally binding obligation of the Purchaser,
enforceable against the Purchaser in accordance with its terms, subject to

                         -----------------
Shares of Common Stock for its own account for investment purposes only and not
with a view to or for distributing or reselling such Shares or any part thereof
or interest therein, without prejudice, however, to the Purchaser's right,
subject to the provisions of this Agreement, at all times to sell or otherwise
dispose of all or any part of such Shares in compliance with applicable federal

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

of any "employee benefit plan", within the meaning of Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended.

                  (g)    Access to Information. The Purchaser acknowledges

that it has been afforded (i) the opportunity to ask such questions as it has
deemed necessary of, and to receive answers from, representatives of the Company
concerning the terms and conditions of the offering of the Shares and the merits
and risks of investing in the Shares; (ii) access to information about the
Company and the Company's financial condition, results of operations, business,
properties, management and prospects sufficient to enable it to evaluate its
investment in the Common Stock; and (iii) the opportunity to obtain such
additional information which the Company possesses or can acquire without
unreasonable effort or expense that is necessary to make an informed investment
decision with respect to the Shares.

                  (h)    Reliance. The Purchaser understands and acknowledges
                         --------

assigned by ant party without the prior written consent of all the parties

covenants of the parties contained in Article IV, the default and remedies
                                      ----------

earlier termination of this Agreement).

         Section 10.10. Counterpart Signatures. 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.

         Section 10.11. Publicity. The Company and the Purchaser shall consult
                        ---------

         Section 10.12. Severability. In case any one or more of the provisions
                        ------------

substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

         Section 10.13. Remedies. In addition to being entitled to exercise all
                        --------
rights provided herein or granted by law, including recovery of damages, the
Purchaser will be entitled to specific performance of the obligations of the
Company under this Agreement and the Company will be entitled to specific
performance of the obligations of the Purchaser hereunder with respect to the
subsequent transfer of Shares. Each of the Company and the Purchaser agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of any breach of its obligations described in the foregoing sentence and
hereby agrees to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.
