have been disclosed publicly by the


                                       4

except with respect to such control person (1) below shall not apply:

                 (1) A petition under the federal bankruptcy laws or any state
insolvency law was filed by or against, or a receiver, fiscal agent or similar

                 (2) Such Person was convicted in a criminal proceeding or is a

                 (3) Such Person was the subject of any order, judgment or
decree, not subsequently reversed, suspended or vacated, of any court of
competent jurisdiction, permanently or temporarily enjoining him from, or
otherwise limiting, the following activities:

                          (i) Acting, as an investment advisor, underwriter,

any conduct or practice in connection with such activity;

                          (ii) Engaging in any type of business practice; or

                          (iii) Engaging in any activity in connection with the
        purchase or sale of any security or commodity or in connection with any
        violation of federal or state securities laws or federal commodities

                 (4) Such person was the subject of any order, judgment or
decree, not


                                       5
<PAGE>

subsequently reversed, suspended or vacated, of any federal or state authority
barring, suspending or otherwise limiting for more than 60 days the right of

                 (5) Such person was found by a court of competent jurisdiction
in a civil action or by the CFTC or SEC to have violated any federal or state
securities law, and the judgment in such civil action or finding by the CFTC or
SEC has not been subsequently reversed, suspended, or vacated.

                 (k) Except for Capstone Partners, L.C. and Crescent Fund LLP
the Company represents that it has had no dealings in connection with this
transaction with any finder or broker who will demand payment of any fee or
commission from the Lender. The Company agrees to indemnify the Lender against
and hold the Lender harmless from any and all liabilities to any persons
claiming brokerage commissions or finder's fees on account of services purported
to have been rendered in connection with this Financing Agreement or the
transactions contemplated hereby.

                 (l) The Company intends to use the proceeds from the Loan for
the purpose of providing operating capital, and the Company anticipates that it
will be able to repay all borrowings from its future cash flow or from further
investment. In addition, the Company believes that it will be able to, and
intends to, comply with all of its obligations and covenants as set forth in the
Related Agreements. Consequently, the Company does not believe, and does not
intend, that the pledge of shares pursuant to the Related Agreements, will be
called. Consequently, and without limiting the generality of the foregoing, the
Company warrants that the pledge of the shares is for security only and not in
contemplation of a sale of such shares by the Lender. The Company has not
arranged for the pledge of the shares as a part of any plan for the further
distribution of the pledged securities.

         5. REPRESENTATIONS AND WARRANTIES OF THE LENDER. The Lender hereby
represents


                                       6
<PAGE>

and warrants to the Company that:

                 (a) If the Lender is a corporation, the Lender has the
corporate power and authority to enter into this Financing Agreement and the
Related Agreements and to perform its obligations hereunder and thereunder. The
execution and delivery by the Lender of this Financing Agreement and the Related
Agreements and the consummation by the Lender of the transactions contemplated
hereby and thereby have been duly authorized by all necessary action on the part
of the Lender. This Financing Agreement and the Related Agreements have been
duly executed and delivered by the Lender and constitute valid and binding
obligations of the Lender, enforceable against it in accordance with their
respective terms, subject to the effects of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and to the application of equitable principles in any
proceeding (legal or equitable).

                 (b) The execution, delivery and performance by the Lender of
this Financing Agreement and the Related Agreements and the consummation of the
transactions contemplated hereby and thereby do not and will not breach or
constitute a default under any applicable law or regulation or of any agreement,
judgment, order, decree or other instrument binding on the Lender.

                 (c) There is no pending, or to the knowledge of the Lender,
threatened, judicial, administrative or arbitral action, claim, suit, proceeding
or investigation which might affect the validity or enforceability of this
Financing Agreement or the Related Agreements.

                 (d) No consent or approval of, or exemption by, or filing with,
any party of governmental or public body or authority is required in connection
with the execution, delivery and performance under this Financing Agreement or
the Related Agreements or the taking of any action contemplated hereunder or
thereunder.

                 (e) The Lender qualifies as an accredited investor for purposes
of Regulation D promulgated under the Securities Act of 1933, as amended (the
"Act") and Rules 501(a) and 215 thereunder. The Lender acknowledges that it has
made an independent due diligence


                                       7
<PAGE>

investigation of the Company and has reviewed each of the Reports and that the
Company has made available to the Lender at a reasonable time prior to the
execution of this Financing Agreement. The Lender has had the opportunity to ask
questions and receive answers concerning the business and affairs of the Company
and the terms and conditions of the sale of securities contemplated by this
Financing Agreement and to obtain any additional information (which the Company
possesses or can acquire without unreasonable effort or expense) as may be
necessary to verify the accuracy of information furnished to the Lender. The
Lender is sophisticated, understands the transactions described in this
Financing Agreement and the Related Documents, and has previous experience in
making loans to corporations in transactions similar to the Loan contemplated by
this Financing Agreement. The Lender has consulted with its legal, financial,
accounting, tax, and investment advisors with respect to the advisability of the
Lender making the Loan to the Company contemplated by this Financing Agreement,
to the extent the Lender has deemed that such consultation is necessary or
appropriate. The Lender (a) is able to bear the loss of the entire principal
amount of the Loan without any material adverse effect on his, her or its
business, operations or prospects, (b) has such knowledge and experience in
financial and business matters that he, she or it is capable of evaluating the
merits and risks of making the Loan to the Company pursuant to this Financing
Agreement, (c) realizes that the Company has a significant need for additional
financing and without such additional financing may be unable to repay the Notes
when due and may have to cease operations, (d) realizes that the advancement of
any funds by the Lender to the Company is highly speculative and subject to
significant risks including, without limitation, those risks identified in the
Reports, and (e) understands that the documents provided to Lender in connection
with the transactions contemplated hereby may contain forward-looking
information that involve risk and uncertainties that could cause actual results
to differ materially from such statements, including, but not limited to, those
risks relating to product demand, pricing, market acceptance, the effect of
economic conditions, the validity and enforceability of intellectual property
rights, the outcome of government regulatory proceedings,


                                       8
<PAGE>

competitive products, risks in product and technology development, the ability
to complete transactions, and other risks identified in the Reports.

                 (f) The Lender understands that the Note, and the shares
issuable upon conversion of the Note, are characterized as "restricted
securities" under the federal securities laws inasmuch as they are being or will
be acquired from the Company in a transaction not involving a public offering
and that under such laws and applicable regulations such securities may be
resold without registration under the Securities Act of 1933 and applicable
state law only in certain limited circumstances. In this regard, the Lender
represents that it is familiar with Rule 144 under the Act, as presently in
effect, and understands the resale limitations imposed thereby and by the Act.
The Lender understands that it is accepting the Note and to the extent the
Lender receives any shares upon conversion or payment of the Note, the Lender
will accept such securities for investment purposes only and without the view
toward the further distribution of such securities except pursuant to a
registration statement that may be effective permitting the public offer or sale
of such securities, or pursuant to an exemption from registration under federal
and applicable state laws. In the event the Lender does attempt to offer or sell
the Note, or underlying securities in the circumstances contemplated by the
preceding sentence, the Lender will do so only in accordance with the
requirements of federal and applicable state laws and interpretations thereof.

                 (g) If the Registration Statement is not effective, the Lender
understands that the certificates evidencing the Shares will bear a legend
substantially in the following form:

        "The securities represented by this certificate have not been registered
        with the Securities and Exchange Commission or the securities commission
        of any state in reliance upon an exemption from registration under the
        Securities Act of 1933, as amended (the "Securities Act"), and,
        accordingly, may not be offered or sold except pursuant to an effective
        registration statement under the securities act or pursuant to an
        available exemption from, or in a transaction not subject to, the
        registration


                                       9
<PAGE>


        requirements of the securities act and in accordance with applicable
        state securities laws."

                 (h) The Lender has no intention or right to obtain the shares
of the Company's common stock pledged by certain affiliates of the Company to
collateralize the repayment of the Note and the Company's performance of its
covenants in this Financing Agreement and the Related Documents except pursuant
to a foreclosure as permitted in the Related Documents following a material
default by the Company, not cured in accordance with the terms of the Related
Documents. The Lender has no intention to sell the pledged shares except after a
foreclosure accomplished pursuant to the preceding sentence. The Lender has not
sought the pledge of the shares pursuant to the Related Documents as a part of
any plan or scheme to distribute any securities in a manner not in compliance
with the requirements of federal and all applicable state laws.

                 (i) In all matters related to this Financing Agreement and the
Related Documents, the Lender is acting strictly on his, her, or its own behalf,
and is not acting as a group with any other person in connection with this
Financing Agreement, the Loan, the Related Documents, or any Loan made, pledge
accepted, or Related Documents executed and accepted by any other person.

                 (j) The Lender is a legal resident of the country set forth
beneath his, her, or its signature to this Financing Agreement, and there is no
basis that the Lender can claim residence in any country other than such
country.

                 (k) The Lender is not, and has never been, an "affiliate" of
the Company as the term "affiliate" is defined in Rule 405 of Regulation C
adopted under the Securities Act of 1933, as amended. If the Lender becomes an
affiliate of the Company at any time during the period the Note is outstanding,
the Lender will notify the Company in writing.

         6. [RESERVED]

         7. COVENANTS OF THE COMPANY The Company covenants and agrees that, so

charge, levy or claim so contested.

its business and do not exceed in the aggregate $100,000.

                 (i) Not declare or pay any cash dividends or authorize or make
any other distribution on any class of equity securities of the Company.

exchange or otherwise dispose of any material part of its properties and assets
except in the ordinary course of business, however, the Company may engage in
any of the foregoing transactions with a parent or subsidiary of the Company so
long as such parent or subsidiary assumes the obligations of the Company
hereunder.

                 (k) Not enter into any agreement or understanding which may,
directly or indirectly, cause or effect a change in "control" as defined in Rule
405 under the Securities Act of 1933, without the prior written consent of the

capacity in any action, proceeding or investigation brought by any stockholder
of the Company, in connection with or as a result of the consummation of the
transactions contemplated by the Related Agreements, or if the Lender is
impleaded in any such action, proceeding or investigation by any person, or (ii)

harmless the Lender, its shareholders, officers, directors, employees,
representatives, attorneys, and assigns from and against and in respect of all
losses, claims, liabilities, damages or expenses resulting from, imposed upon or
incurred by the Lender, directly or indirectly, and reimburse such Lender for
its reasonable legal and other expenses (including the cost of any investigation

employee or controlling person shall have any liability to the Company or any
person asserting claims on behalf of or in right of the Company in connection
with or as a result of the consummation of the transactions hereunder, except as
provided in or contemplated by the Note or Related Agreements unless such action
by the Lender or any affiliate, partner, director, agent, employee, or
controlling person results from the fraud, negligence, criminal act or omission,
or other action or omission by such person that violates any applicable law or
regulation

                 (b) Notwithstanding Section 9(a) above, the Company shall have
no obligation under this Section 9 if any such action, proceeding, or
investigation arises out of or relates to any fraudulent, negligent, or criminal
act or omission of the Lender or any affiliate, partner, director, agent,

becomes involved in any capacity in any action, proceeding or investigation
brought by the Securities and Exchange Commission, any self-regulatory
organization or other body having jurisdiction in connection with or as a result
of the consummation of the transactions contemplated by the Related Agreements
(which is an action, proceeding or investigation brought primarily against the
Lender and is not an action, proceeding or investigation brought primarily
against the Company or its officers, directors, any shareholder or employees),
or (iii) if the Company is impleaded in any such action, proceeding or
investigation by any person, then in any


                                       14

such case of Sections 9(c)(i)(ii) or (iii), the Lender hereby agrees to
indemnify, defend and hold harmless the Company from and against and in respect
of all losses, claims, liabilities, damages or expenses resulting from, imposed
upon or incurred by the Company, directly or indirectly, and reimburse such
Company for its reasonable legal and other expenses (including the cost of any
investigation and preparation) incurred in connection therewith, as such
expenses are incurred. The foregoing indemnification does not include any
obligation to reimburse the Company for internal and overhead costs for the time
of any officers or employees of the Company devoted to appearing and preparing
to appear as witnesses, assisting in preparation for hearings, trials or
pretrial matters, or otherwise with respect to inquiries, hearing, trials, and
other proceedings relating to the subject matter of the Note and Related
Agreements. The indemnification and reimbursement obligations of the Lender
under this paragraph shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Company and the
Lender. The Company also agrees that neither the Lender nor any such affiliate,
partner, director, agent, employee or controlling person shall have any
liability to the Company or any person asserting claims on behalf of or in right
of the Company in connection with or as a result of the consummation of the
transactions hereunder, except as provided in or contemplated by the Note or
Related Agreements unless such action by the Lender or any affiliate, partner,
director, agent, employee, or controlling person results from the fraud,
negligence, criminal act or omission, or other action or omission by such person
that violates any applicable law or regulation.

                 (d) Notwithstanding Section 9(c) above, the Lender shall have
no obligation under this Section 9 if any such action, proceeding, or
investigation arises out of or relates to any fraudulent, negligent, or criminal
act or omission of the Company or any affiliate, partner, director, officer,
shareholder, agent, employee, or controlling person of the Company in connection
with the transactions contemplated by this Financing Agreement or otherwise, or
other action or omission by such person that violates any applicable law or
regulation.

further that the Company is, prior to or simultaneously with such transfer,
furnished with written notice of the name and address of such transferee or
assignee, and such assignee agrees in writing to be bound by the terms hereof
and provided further that, if the Note is only assigned or transferred in part,
then such assignment shall only be made in part on an appropriate proportionate
basis. If there is a conflict between this provision and any provision of the
Related Agreements, this provision shall govern.
