         1.3 PURCHASER REPRESENTATIONS AND WARRANTIES.

         In connection with the purchase and sale of the Preferred Shares and
the Warrants hereunder, the Purchaser represents and warrants to the Sellers
that:

                  (a) The Purchaser is acquiring the Preferred Shares and the
Warrants for its own account for investment purposes only and not with a view
to, or intention of, making a distribution thereof within the meaning of the
Securities Act of 1933, as amended (the "Act"), or any applicable state
securities laws, and the Preferred Shares and the Warrants will not be
transferred or disposed of in contravention of the Act or any applicable state
securities laws.

                  (b) The Purchaser understands (i) that the Preferred Shares
and the Warrants have not been registered under the Act by reason of their
issuance in a transaction exempt from the registration and prospectus delivery
requirements of the Act pursuant to Section 4(2) thereof and have not been
registered under any state or other jurisdiction's securities laws, and (ii) the
Sellers' reliance on such exceptions is predicated on the Purchaser's
representations set forth herein, and (iii)

                                      -2-
<PAGE>

that the Preferred Shares and the Warrants must be held indefinitely unless the
sale or other transfer thereof is subsequently registered or exemptions from
such registration requirements are available. The Purchaser is further aware
that the Sellers are under no obligation to register the Preferred Shares or the
Warrants under the Act or any state or other jurisdiction's securities laws or
to assist the Purchaser in complying with any exemption from such registration
requirements.

                  (c) The Purchaser acknowledges that investment in the
Preferred Shares and the Warrants involves substantial risks, including the risk
of total loss of its investment in the Preferred Shares and the Warrants. The
Purchaser (i) is able to bear the economic risk of its investment in the
Preferred Shares and the Warrants for an indefinite period of time; (ii) has
adequate means, other than the Preferred Shares, the Warrants or funds invested
therein, of providing for its current and foreseeable needs; (iii) has no
foreseeable need to sell or otherwise dispose of any of the Preferred Shares or
the Warrants; and (iv) has sufficient net worth to sustain a loss of its entire
investment in the Preferred Shares and in the Warrants in the event such loss
should occur.

                  (d) The Purchaser is an "accredited investor," as such term is
defined in Rule 501 of Regulation D promulgated under the Act. The Purchaser and
its agents and representatives have such knowledge and experience in financial
and business matters as to enable them to utilize the information made available
to them in connection with the transactions contemplated hereby to evaluate the
merits and risks of an investment in the Preferred Shares and the Warrants and
to make an informed decision with respect thereto, and such an evaluation and
informed decision have been made.

                  (e) The Purchaser has the legal capacity and authority to
enter into and perform all of its obligations under this Agreement. This
Agreement constitutes the legal, valid and binding obligation of the Purchaser,
enforceable against the Purchaser in accordance with its terms. The execution,
delivery and performance of this Agreement does not and will not conflict with,
violate, cause a breach of or constitute a default under (i) any agreement,
contract or other instrument or obligation to which the Purchaser is a party or
by which the Purchaser is bound or (ii) any judgment, order, decree, statute,
rule or regulation to which the Purchaser is subject.

                  (f) The Purchaser understands that the Preferred Shares and
the Warrants it is purchasing are characterized as "restricted securities" under
the federal securities laws inasmuch as they are being acquired from the issuer
in a transaction not involving a public offering and that under such laws and
applicable regulations such Preferred Shares and such Warrants may be resold
without registration under the Act, only in certain limited circumstances. In
this connection, such Purchaser represents that it is familiar with SEC Rule
144, as presently in effect, and understands the resale limitations imposed
thereby and by the Act.

                  (g) The Purchaser acknowledges that the Sellers may, between
the date hereof and the Warrant Closing, exercise some or all of the Warrants
and under such circumstances, Sellers shall have no obligations to the Purchaser
to sell any Warrants to the extent so exercised, and, further, shall have no
obligation to sell to the Purchaser any shares of Common Stock acquired by the
Sellers pursuant to such exercise.

                  (a) The Preferred Shares and the Warrants to be sold at the

                  (b) The Sellers have the legal capacity and authority to enter
into and perform all of its obligations under this Agreement. This Agreement
constitutes the legal, valid and binding obligation of the Sellers, enforceable
against the Sellers in accordance with its terms. The execution, delivery and
performance of this Agreement does not and will not conflict with, violate,
cause a breach of or constitute a default under (i) any agreement, contract or
other instrument or obligation to which the Purchaser is a party or by which the
Sellers are bound or (ii) any judgment, order, decree, statute, rule or
regulation to which the Sellers are subject.

                                   ARTICLE 2.
