     3. Representations and Warranties of the Subscriber. The undersigned hereby
represents and warrants to, and agrees with, the Company as follows:

         (a) If a natural person, the undersigned is: a bona fide resident of

undersigned; has had a reasonable opportunity to ask questions of the Company
and its representatives; and the Company has answered all inquiries that the
undersigned or the undersigned's representatives have put to it. The undersigned
has had access to all additional information necessary to verify the accuracy of
the information set forth in this Agreement and any other materials furnished
herewith, and has taken all the steps necessary to evaluate the merits and risks
of an investment as proposed hereunder.

         (c) The undersigned or the undersigned's purchaser representative has
such knowledge and experience in finance, investments and other business matters
so as to be able to protect the interests of the undersigned in connection with
this transaction, and the undersigned's investment in the Company hereunder is
not material when compared to the undersigned's total financial capacity.

         (d) The undersigned understands the various risks of an investment in
the Company as proposed herein and can afford to bear such risks, including,
without limitation, the risks of losing the entire investment.

         (e) The undersigned acknowledges that no market for the Shares
presently exists and none may develop in the future and that the undersigned may
find it impossible to liquidate the investment at a time when it may be
desirable to do so, or at any other time.

         (f) The undersigned has been advised by the Company that none of the
Shares have been registered under the Securities Act of 1933, as amended (the
"Act"), that the Shares will be issued on the basis of the statutory exemption
provided by Section 4(2) of the Act or Regulation D promulgated thereunder, or
both, relating to transactions by an issuer not involving any public offering
and under similar exemptions under certain state securities laws, that this
transaction has not been reviewed by, passed on or submitted to any Federal or
state agency or self-regulatory organization where an exemption is being relied
upon, and that the Company's reliance thereon is based in part upon the
representations made by the undersigned in this Agreement. The undersigned
acknowledges that the undersigned has been informed by the Company of, or is
otherwise familiar with, the nature of the limitations imposed by the Act and
the rules and regulations thereunder on the transfer of Shares. In particular,
the undersigned agrees that no sale, assignment or transfer of any of the Shares
shall be valid or effective, and the Company shall not be required to give any
effect to such a sale, assignment or transfer, unless (i) the sale, assignment
or transfer of such Shares is registered under the Act, it being understood that
the Shares are not currently registered for sale and that the Company has no
obligation or intention to so register the Shares, or (ii) such Shares are sold,
assigned or transferred in accordance with all the requirements and limitations
of Rule 144 under the Act, it being understood that Rule 144 is not available at
the present time for the sale of the Shares, or (iii) such sale, assignment or
transfer is otherwise exempt from registration under the Act. The undersigned
further understands that an opinion of counsel and other documents may be
required to transfer the Shares. The undersigned acknowledges that the Shares
shall be subject to a stop transfer order and the certificate or certificates
evidencing any Shares shall bear the following or a substantially similar legend
or such other legend as may appear on the forms of Warrants and such other
legends as may be required by state Shares or blue sky laws:

         "The Shares represented by this certificate have not been
         registered under the Securities Act of 1933, as amended (the
         "Act"), or any state securities laws and neither such Shares
         nor any interest therein may be offered, sold, pledged,
         assigned or otherwise transferred unless (1) a registration
         statement with respect thereto is effective under the Act and
         any applicable state securities laws, or (2) the Company
         receives an opinion of counsel to the holder of such Shares,
         which counsel and opinion are reasonably satisfactory to the
         Company, that such Shares may be offered, sold, pledged,
         assigned or transferred in the manner contemplated without an
         effective registration statement under the Act or applicable
         state securities laws."

         (g) The undersigned will acquire the Shares for the undersigned's own
account (or for the joint account of the undersigned and the undersigned's
spouse either in joint tenancy, tenancy by the entirety or tenancy in common)
for investment and not with a view to the sale or distribution thereof or the
granting of any participation therein, and has no present intention of
distributing or selling to others any of such interest or granting any
participation therein.

         (h) It never has been represented, guaranteed or warranted by any
broker, the Company, any of the officers, directors, shareholders, partners,
employees or agents of either, or any other persons, whether expressly or by
implication, that:

             (i) the Company or the undersigned will realize any given
     percentage of profits and/or amount or type of consideration, profit or
     loss as a result of the Company's activities or the undersigned's
     investment in the Company; or

             (ii) the past performance or experience of the management of the
     Company, or of any other person, will in any way indicate the predictable
     results of the ownership of the Shares or of the Company's activities.

         (i) The undersigned is not subscribing for Shares as a result of or
subsequent to any advertisement, article, notice or other communication
published in any newspaper, magazine or similar media or broadcast over
television or radio, or presented at any seminar or meeting, or any solicitation
of a subscription by a person other than a representative of the Company with
which the undersigned had a pre-existing relationship in connection with
investments in Shares generally.

         (j) The undersigned is not relying on the Company with respect to the
tax and other economic considerations of an investment.

         (k) Without limiting any of the undersigned's other representations and
warranties hereunder, the undersigned acknowledges that the undersigned has
reviewed and is aware of the risk factors described in the Company's
Registration Statement on Form S-3 (Reg. No. 333-95609) declared effective on
February __, 2000.

warranties and agreements made by the undersigned herein shall survive the
execution and delivery of this Agreement and the purchase of the Shares.

     4. Concerning the Escrow Agent. To induce Buchanan Ingersoll Professional
Corporation to serve as the Escrow Agent and to act in such capacity hereunder,

such gross negligence or willful misconduct that are successfully asserted
against the Escrow Agent, the undersigned and the Company hereby agree to
jointly and severally indemnify and hold harmless the Escrow Agent from and
against any and all losses, liabilities, claims, actions, damages and expenses,
including, without limitation, reasonable attorneys' fees and disbursements,
arising out of or in connection with this Escrow Agreement.

             (b) The Subscriber understands and agrees that, notwithstanding its
duties as Escrow Agent under the Escrow Agreement, the Escrow Agent is legal
counsel to the Company, and, accordingly, neither any services provided by the
Escrow Agent as Escrow Agent nor any provisions of the Escrow Agreement, either
express or implied, shall restrict or inhibit the Escrow Agent in any way from
representing the Company or its affiliates in any action, dispute, controversy,
arbitration, suit or negotiation arising under this Agreement, the Escrow
Agreement or under any other agreement or in any manner or context whatsoever,
whether or not directly or indirectly involving the Company or its affiliates.

     5. Indemnification. The undersigned acknowledges that the undersigned
understands the meaning and legal consequences of the representations and
warranties contained in Section 3 hereof, and agrees to indemnify and hold
harmless the Company, its officers, directors, partners, employees, agents and
controlling persons thereof, past, present or future, from and against any and
all loss, damage or liability due to or arising out of a breach of any such
representation or warranty.

     6. Transferability. Neither this Agreement, nor any interest of the
undersigned herein, shall be assignable or transferable by the undersigned in
whole or in part except by operation of law.

     7. Miscellaneous.

             (a) This Agreement sets forth the entire understanding of the
parties with respect to the subject matter hereof, supersede all existing
agreements among them concerning such subject matter, and (subject to Section
7(g)) may be modified only by a written instrument duly executed by the party to
