Company shall designate. If, at the Closing, any of the Subscribers shall have
failed to tender the Purchase Price for the Investment Units to be purchased by
such Subscriber at the Closing or any of the conditions specified herein shall

at its election, be relieved of all of its obligations under this Agreement to

                 2.3 FURTHER UNDERTAKINGS BY SUBSCRIBERS. Each Subscriber

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to the Subscriber as follows:

                 3.1 DUE ORGANIZATION. It is a corporation duly organized,
validly existing, and in good corporate standing under the laws of the State of
Delaware.

                 3.2 SALE OF SECURITIES. The Notes and Shares included in each
Investment Unit will be duly authorized and enforceable.

         4. REPRESENTATIONS AND WARRANTIES OF SUBSCRIBER. The Subscriber hereby
represents and warrants as follows:

                 4.1 RELIANCE ON REPRESENTATIONS AND WARRANTIES. The Subscriber
acknowledges that the Company is offering the Investment Units in reliance upon
the representations, warranties, and other information set forth by the
Subscriber. The Subscriber undertakes to notify the Company immediately of any
changes in any of the representations, warranties, and other information
contained herein.

                 4.2 SUBSCRIBER'S AUTHORITY. The Subscriber represents that he
has full legal power and authority to enter into this Agreement and to purchase
the Investment Units.

                 4.3 RISKS ASSOCIATED WITH OFFERING. The Subscriber recognizes
that the purchase of the Investment Units involves a high degree of risk in that
(i) he may not be able to liquidate his investment; (ii) transferability is
extremely limited; and (iii) in the event of a disposition, he could sustain the
loss of his entire investment. In addition, the Subscriber recognizes


                                      -3-


<PAGE>   11



additional risks, including, but not limited to, those set forth in the Overview
of Financing and the Information Statement of the Company, dated as of November
14, 1996 (the "Information Statement"), which risks the Subscriber has carefully
read and considered.

                  4.4 INVESTMENT REPRESENTATIONS. The Subscriber represents that
he is acquiring the Investment Units hereunder for his own account and not with
a view to reselling or otherwise distributing such securities in violation of
any Federal or state securities laws and understands and agrees that the
securities to be issued hereunder are restricted on transfer and must be held
unless (i) they are registered under the Securities Act of 1933, as amended,
(the "Act") or (ii) an exemption from registration is available, and the Company
has received an opinion of counsel, in form and substance satisfactory to it, to
such effect. There can be no assurance that the Company will make available to
the public at any time in the future information necessary to enable security
holders to make routine sales of securities pursuant to Rule 144 under the Act.

                  4.5 SOPHISTICATION AND ABILITY TO RISK LOSS OF INVESTMENT. The
Subscriber acknowledges that he has prior investment experience, including
investment in non-listed and non-registered securities, or he has employed the
services of an investment advisor, attorney or accountant to read all of the
documents furnished or made available by the Company both to him and to all
other prospective subscribers in connection with the Offering and to evaluate
the merits and risks of such an investment on his behalf; that he recognizes the
highly speculative nature of this investment; that a noteholder, including the
Subscriber, may not at any time demand the withdrawal of capital from the
Company; and that he is able to bear the economic risk he hereby assumes,
namely, of holding the Investment Units for an indefinite period of time and of
losing his entire investment. The Subscriber represents that his overall
commitment to investments that are not readily marketable is not excessive in
view of his net worth and financial circumstances and the purchase of the
Investment Units will not cause such commitment to become excessive, and that
the investment is a suitable one for the Subscriber.

                  4.6 ACCESS TO INFORMATION. The Subscriber acknowledges receipt
of the Overview of Financing and the Information Statement, which contains
certain audited and unaudited financial  statements of the Company. The
Subscriber hereby represents and acknowledges that he has carefully read the
Overview of Financing and Information Statement furnished by the Company during
the course of this transaction and all additional information regarding the
Company that he had requested or desired to know; that all documents which could
be reasonably provided have been made available for his inspection and review;
that he has been afforded the opportunity to ask questions of and receive
answers from duly authorized officers or other representatives of the Company
concerning the terms and conditions of the Offering, and that he has received
any additional information that he has requested. The Subscriber further
represents and acknowledges that because certain of the financial statements and
financial information included in the Information Statement are unaudited, that
such statements and information are subject to change and that the final
financial statements may report the Company's results of operations for and
financial condition as of the respective dates of such statements to be less
than and/or worse than the financial statements provided.

<PAGE>   12



                  4.7 FINDINGS OR RECOMMENDATIONS. The Subscriber is aware that
neither the Securities and Exchange Commission (the "SEC") nor the Attorney
General of the State of Delaware nor any other federal or state agency has made
any findings or determination as to the fairness of the Investment Units, nor
has any recommendation or any endorsement of the Investment Units has been made
and the Investment Units offered are not registered under federal, Delaware or
any other state law and the securities are restricted securities within the
meaning of the U.S.  federal  securities laws because of the Company's
representations that this is intended to be a non-public offering pursuant to
Section 4(2) and/or 4(6) of the Act.

                  4.8 REGISTRATION EXEMPTION. The Subscriber understands that
the Investment Units have not been registered under the Act by reason of a
claimed exemption under the provisions of the Act which depends, in part, upon
his investment intention. In this connection, the Subscriber understands that it
is the position of the SEC that the statutory basis for such exemption would not
be present if his representation merely meant that his present intention was to
hold such securities for a short period, such as the capital gains period of tax
statutes, for a deferred sale, for a market rise, assuming that a market
develops, or for any other fixed period. The Subscriber realizes that, in the
view of the SEC's position, a purchase now with an intent to resell would
represent a purchase with an intent inconsistent with his representation to the
Company, and the SEC might regard such a sale or disposition as a deferred sale
to which the exemption is not available.

                  4.9 LIMITED AND NO PUBLIC MARKET FOR  SECURITIES.  The
Subscriber understands that no public market for the Notes exists and no public
market can be expected to develop for the Notes. The Company's Common Stock
trades on the NASDAQ System. The Subscriber understands that trading of the
Company's Common Stock has been limited and no assurance can be given that an
active public trading market for the Common Stock will develop, or if developed,
be sustained. The Subscriber understands that it may not be possible to
liquidate an investment in the Investment Units on an emergency basis. The
Subscriber understands that the Company makes no representation or warranty
regarding its fulfillment in the future of any reporting requirements under the
Securities Exchange Act of 1934, as amended, or its dissemination to the public
of any current financial or other information concerning the Company, if
required as one of the conditions of the availability of any exemption. The
Subscriber understands and hereby acknowledges that the Company is under no
obligation to register the Investment Units under the Act.

                  4.10 LEGENDS. The Subscriber consents to the placement of any
legends required by state securities laws and of a legend, in a form
satisfactory to the Company's counsel, on any certificate or other document
evidencing the Notes or the Shares indicating that they have not been registered
under the Act and setting forth or referring to the  restrictions  on
transferability and sale thereof. The Subscriber is aware that the Company will
