(each such investor is a "PURCHASER" and all such investors are, collectively,
the "PURCHASERS").

     WHEREAS, the Company and the Purchasers previously entered into a Secured
Convertible Debenture Purchase Agreement dated as of June 22, 2000 (the
"Convertible Purchase Agreement") as amended by that certain First Amendment to
Secured Convertible Debenture Purchase Agreement dated as of July 17, 2000 (the
"Amendment", along with the Convertible Purchase Agreement is herein
collectively referred to as the "Purchase Agreement") pursuant to which the
Company issued and sold to the Purchasers, and the Purchasers have purchased an
aggregate principal amount of $500,000 of the Company's 12% Secured Convertible
Debentures, due June 30, 2001 (the "Outstanding Debentures") and 250,000 of the
Company's Common Stock Purchase Warrants expiring June 30, 2003 (the
"Outstanding Warrants");

     WHEREAS, pursuant and subject to the terms and conditions of the Purchase
Agreement the Company and the Purchasers agreed that upon the occurrence of
certain events which have not taken place (the "Purchase Conditions") the
Purchasers would purchase an additional $500,000 of the Company's 12% Secured
Convertible Debentures (as defined in the First Amendment to Secured Convertible
Debenture Purchase Agreement, the "Subsequent Purchase Price");

     WHEREAS, the Company has requested of the Purchasers that they purchase
debentures in the amount of the Subsequent Purchase Price and the Purchasers are
willing to purchase debentures in the amount of the Subsequent Purchase Price
notwithstanding the failure of the Purchase Conditions to occur;

     WHEREAS, subject to the terms and conditions set forth in this Agreement,
the Company desires to issue and sell immediately to the Purchasers and the
Purchasers, severally and not jointly, desire to purchase from the Company an
aggregate principal amount of $500,000 of the Company's 12% Secured Convertible
Debentures, due May 31, 2002, which shall be in the form of EXHIBIT A (the "New

collectively deemed to be the "Debentures" wherever such term is used), and
which are convertible into shares of the Company's common stock, $ .0001 par

US$ (United States Dollars);

     WHEREAS, subject to the terms and conditions set forth in this Agreement,
the Company and the Purchasers desire to amend and modify the Purchase
Agreement.

     NOW, THEREFORE, IN CONSIDERATION of the mutual covenants contained in this
Agreement, and for other good and valuable consideration the receipt and
adequacy are hereby acknowledged, the Company and the Purchasers agree as
follows:
<PAGE>
     1.1 DOCUMENT MODIFICATION.

     The Purchase Agreement (as was previously modified by the Amendment) shall
be amended and modified hereby to reflect the following:

     (A)  Paragraph 1.1(a)(i) shall be amended and modified such that the term
          "Second Tranche" shall be deemed to mean $500,000 of New Debentures to
          be purchased on the date hereof notwithstanding the fact that the
          Effective Date shall not have occurred.

     (B)  Paragraph 2.1(q) shall be deemed to be deleted in its entirety and
          replaced with the following "(q) SENIORITY. No indebtedness of the
          Company is senior to the Debentures in right of payment, whether with
          respect to interest or upon liquidation or dissolution, or otherwise,
          except for transactions in an aggregate amount of up to $1,000,000
          entered into pursuant to the form of Operating Agreement attached
          hereto as EXHIBIT A and made a part hereof (the "Operating
          Agreement").

     The Outstanding Debentures shall be amended and modified hereby to reflect
the following:

     (A)  Section 3(a)(iv) shall be amended and modified to reflect that the
          amount permitted for a default by the Company (solely with regard to
          obligations other than the Debentures) giving rise to an Event of
          Default under the Debentures shall be increased from twenty-five
          thousand dollars ($25,000) to Two Hundred Fifty Thousand ($250,000)
          Dollars; and

     (B)  Section 4(c)(ii)(c) the text of which reads "combine (including by way
          of reverse stock split) outstanding shares of Common Stock into a
          smaller number of shares" is hereby deemed to be deleted and of no
          further force or effect.

     (C)  Section 10 shall be amended and modified to delete the reference to
          the SBA Loan and to provide the Company the right to subordinate the
          Debentures to the transactions pursuant to the Operating Agreement in
          an amount of up to $1,000,000. The Security Agreement entered into
          between Purchasers and the Company shall be governed by this amended
          provision to the Debenture.

     The Outstanding Warrants shall be amended and modified hereby to reflect
the following:

     (A)  Section 8(a)(iii) the text of which reads "combine outstanding shares
          of Common Stock into smaller number of shares" is hereby deemed to be
          deleted and of no further force or effect.

                                       2

     4.3 EXECUTION. This Agreement may be executed in two or more counterparts,
all of which when taken together shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and
delivered to the other party, it being understood that both parties need not
sign the same counterpart. In the event that any signature is delivered by
facsimile transmission, such signature shall create a valid and binding
obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

     4.4 SEVERABILITY. In case any one or more of the provisions of this
Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affecting or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.
