its terms, except that the enforceability hereof may be subject to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium or other similar
laws of general application, now or hereafter in effect, relating to or
affecting the enforcement of creditors' rights generally and general principles
of equity;

     (b) the execution, delivery and performance by Purchaser of this Agreement
and the consummation of the transactions contemplated hereby will not violate or

     (c) other than as may be required in connection with or in compliance with
the provisions of the HSR Act, no authorization, consent or approval of, or any
filing with any governmental body or authority or any other person is necessary
for consummation by Purchaser of the transactions contemplated hereby;

     (d) Purchaser has been advised that the Options and the shares of Common
Stock to be acquired upon exercise of the Options have not been registered under
the Securities Act, or any state securities laws and, therefore, cannot be
resold unless they are registered under the Securities Act and applicable state
securities laws or unless an exemption from such registration requirements is
available. Purchaser is aware that Issuer is under no obligation to effect any
such registration or comply with any exemption from registration, except as
required under the Option Agreement. Purchaser understands that no public market
now exists for any securities issued by Issuer. Purchaser is purchasing the
Options, and the Common Stock to be acquired upon exercise of the Options,
hereunder for its own account for investment, not as a nominee or agent, and not
with a view to, or for resale in connection with, the distribution thereof.
Purchaser has such knowledge and experience in financial and business matters
that Purchaser is capable of evaluating the merits and risks of such investment,
is able to incur a complete loss of such investment and is able to bear the
economic risk of such investment for an indefinite period of time. Purchaser is
an "accredited investor" as such term is defined in Rule 501 of Regulation D
under the Securities Act; and

     (e) Purchaser acknowledges that he has received sufficient information
regarding Issuer to make an informed decision with respect to the purchase of
the Options, and the Common Stock to be acquired upon exercise of the Options.
