                                                                               2


            (a) Each Purchaser has been given the opportunity to obtain
information and to ask questions and receive answers about such information, the
Company and the business and prospects of the Company which such Purchaser deems
necessary to evaluate the merits and risks related to such Purchaser's
investment in the Common Stock.

            (b) Each Purchaser further represents and warrants that (i) such
Purchaser's financial condition is such that such Purchaser can afford to bear
the economic risk of holding the shares of Common Stock for an indefinite period
of time and has adequate means for providing for such Purchaser's current needs
and personal contingencies, (ii) such Purchaser can afford to suffer a complete
loss of his or its investment in the shares of Common Stock, (iii) such
Purchaser has evaluated and understands the risks and terms of investing in the
Common Stock and (iv) such Purchaser's knowledge and experience in financial and
business matters are such that such Purchaser is capable of evaluating the
merits and risks of such Purchaser's purchase of the shares of Common Stock as
contemplated by this Agreement or, in the alternative, such Purchaser has
obtained such professional advice as such Purchaser determined was necessary to
enable such Purchaser to evaluate such merits and risks.

            (c) Each Purchaser is an "accredited investor" as such term is
defined in Regulation D promulgated under the Securities Act of 1933, as
amended. Each Purchaser has such knowledge and experience in financial and
business matters that it is capable of evaluating the relative merits and risks
of purchasing the Common Stock.

            (d) Such Purchaser is purchasing its shares of Common Stock for
investment for its own account and not with a view to, or for sale in connection
with, any distribution thereof.

            (e) Such Purchaser is a corporation, duly organized, validly
existing and in good standing, under the laws of its jurisdiction of
organization.

powers, and have been duly authorized by all necessary action on the part of
such Purchaser. This Agreement has been duly executed and delivered by such
Purchaser. Assuming due authorization, execution and delivery by the Company and
the other Purchasers, this Agreement constitutes a valid and binding agreement
of such Purchaser, enforceable against such Purchaser in accordance with its
terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting
enforcement or creditors' rights generally, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief, or other equitable
remedies and (iii) with respect to provisions relating to indemnification and
contribution, as limited by considerations of public policy.

            (g) The execution, delivery and performance by such Purchaser of
this Agreement require no order, license, consent, authorization or approval of,
or exemption by, or action by or in respect of, or notice to, or filing or
registration with, any governmental body, agency or official except


                                                                               3


such as have been obtained or except where the failure to obtain any such order,
license, consent, authorization, approval or exemption or give any such notice
or make any filing or registration would not, in the aggregate, reasonably be
expected to adversely affect the ability of such Purchaser to perform its
obligations hereunder.

            (h) The execution, delivery and performance of this Agreement by
such Purchaser will not, with or without the giving of notice or lapse of time,
or both, (i) conflict with the certificate of incorporation or by-laws or
similar constitutive documents of such Purchaser or (ii) result in any breach of
any terms or provisions of, or constitute a default under, or conflict with any
material contract, agreement or instrument to which such Purchaser is a party or
by which such Purchaser is bound, except for such breaches, defaults or
conflicts which, individually or in the aggregate, would not be likely to have a
material adverse effect on the financial position, results of operations or
business of such Purchaser or (iii) violate any material provision of law,
statute, rule or regulation to which it is subject or any material order,
judgment or decree applicable to such Purchaser.

Agreement shall be severable in the event that any of the provisions hereof are
held by a court of competent jurisdiction to be invalid, void or otherwise

jurisdiction of such courts for itself and in respect of its property with
respect to such action. The parties hereto irrevocably agree that venue would be
proper in such court, and hereby irrevocably waive any objection that such court

rendered in any action or proceeding based thereon.
