            decree of any court, administrative agency or other governmental
            body applicable to the Purchaser, or any of its properties or

                  can reasonably benefit from the investment based upon net
                  worth, income, overall investment objectives and portfolio
                  structure, (b) that the Purchaser's overall commitment to
                  investments which are not readily marketable is not
                  disproportionate to the Purchaser's net worth, and that the
                  Securities will not cause such overall commitment to become
                  excessive, and (c) that the Purchaser is able to bear the
                  economic risk of the Securities, including the loss of the
                  entire value of the investment. Additionally, the Purchaser
                  understands that that there are restrictions on the
                  Purchaser's right to liquidate the Securities.

                        (iii) The Purchaser has reviewed the Risk Factors
                  included in the SEC Documents, and understands the Risk
                  Factors describing that the Company (a) has substantial
                  liabilities, (b) may not be able to obtain sufficient funds to
                  grow its business and any subsequent financings may be on
                  terms adverse to the Securities, and (c) is currently not
                  profitable.

                        (iv) The Purchaser has (a) previously invested in
                  unregistered securities and (b) sufficient financial and
                  investing expertise to evaluate and understand the risks of
                  the Securities.

                        (v) The Purchaser has received from the Company, and is
                  relying on, no representations or projections (except as set
                  forth in this Agreement or the SEC Documents) with respect to
                  the Company's business and prospects.

                        (vi) The Purchaser is an "accredited investor" within
                  the meaning of Regulation D under the Securities Act.

<PAGE>

                        (vii) The Purchaser is acquiring the Securities for
                  investment purposes only without intent to distribute the
                  same, and acknowledges that the Securities have not been
                  registered under the Securities Act and applicable state
                  securities laws, and accordingly, constitute "restricted
                  securities" for purposes of the Securities Act and such state
                  securities laws.

                        (viii) The Purchaser understands that he will not be
                  able to transfer the Securities except upon compliance with
                  the registration requirements of the Securities Act and
                  applicable state securities laws or exemptions therefrom.

                        (ix) The Purchaser understands that the certificates
                  and/or instruments evidencing the Securities will contain a
                  legend to the foregoing effect.

Officer represents and warrants that as of the date of this Agreement:

      under this Agreement are not subject to any lien, claim, encumbrance or
      restriction of any nature.

            (b) Each Company Officer has all requisite power and authority to
      execute, deliver and perform the sections of this Agreement to which he is
      party, and to consummate the transactions contemplated thereby. This
      Agreement has been duly executed and delivered by each Company Officer as
      to the sections to which he is party. This Agreement constitutes the
      legal, valid and binding obligation of each Company Officer as to the
      sections to which he is party, enforceable against such Company Officer in
      accordance with its terms, subject as to enforcement of remedies to
      applicable bankruptcy, insolvency, reorganization or similar laws
      affecting generally the enforcement of creditors' rights and the relief of
      debtors.

      5. MISCELLANEOUS.

            5.1 Confidentiality.

                  (a) The Purchaser agrees to keep confidential any and all

            information (a) upon the order of any court or administrative
            agency, (b) upon the request or demand of any regulatory agency or
            authority having jurisdiction over the Purchaser, (c) which has been
            publicly disclosed other than as a result of a breach of this


                                       6

            Confidential" and provides the Purchaser, such advisors and
            representatives with the opportunity to accept or refuse to accept

            confidentiality agreement in form reasonably satisfactory to the
            Company and the Purchaser.

                  (c) Nothing herein shall require the Company to disclose

            Amount at Closing.

                  (b) Each of the Company and the Purchaser shall be responsible
            for all of its fees and expenses in connection with this

            5.13 Maximum Interest. It is expressly stipulated and agreed to be
      the intent of the Company and the Purchaser at all times to comply with
      the applicable law governing the maximum rate of interest payable on or in
      connection with all indebtedness and transactions hereunder (or applicable
      United States federal law to the extent that it permits Purchaser to
      contract for, charge, take, reserve or receive a greater amount of
      interest). If the applicable law is ever judicially interpreted so as to
      render usurious any amount of money or other consideration called for
      hereunder, or contracted for, charged, taken, reserved or received with
      respect to any loan or advance hereunder, or if acceleration of the
      maturity of the Note results in the Company's having paid any interest in
      excess of that permitted by law, then it is the Company's and the
      Purchaser's express intent that all excess cash amounts theretofore
      collected by Purchaser be credited on the principal balance of the Note
      (or if the Note has been or would thereby be paid in full, refunded to the
      Company), and the provisions of this Agreement immediately be deemed
      reformed and the amounts thereafter collectible hereunder reduced, without
      the necessity of the execution of any new document, so as to comply with
      the applicable law, but so as to permit the recovery of the fullest amount
      otherwise called for hereunder. The right to accelerate maturity of the
      Note does not include the right to accelerate any interest which has not
      otherwise accrued on the date of such acceleration, and the Purchaser does
      not intend to collect any unearned interest in the event of acceleration.

            5.14 Enforcement Costs. If any legal action or other proceeding is
      brought for the enforcement of this Agreement, or because of an alleged
      dispute, breach, default or misrepresentation in connection with any
      provisions of this Agreement, the successful or prevailing party or
      parties shall be entitled to recover reasonable attorneys' fees, court
      costs and expenses even if not taxable as court costs (including, without
      limitation, all such fees, costs and expenses incident to appeals),
      incurred in that action or proceeding, in addition to any other relief to
      which such party or parties may be entitled.

            5.15 JURY TRIAL. THE COMPANY AND THE PURCHASER HEREBY KNOWINGLY,
      VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT WHICH IT MAY HAVE TO A TRIAL
      BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION BASED HEREON, OR
      ARISING OUT OF, UNDER OR IN ANY WAY CONNECTED WITH THE DEALINGS BETWEEN
      THE COMPANY AND THE PURCHASER, THIS AGREEMENT OR ANY DOCUMENT EXECUTED IN
      CONNECTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING,
      STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF ANY PARTY HERETO OR
      THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND
      WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE.
