Section 2.                PAYMENT.

         (a) The Company shall pay the then outstanding principal amount of this
Debenture on April 16, 2006. Interest shall accrue on the principal amount from
time to time outstanding under this Debenture at the Interest Rate from the date
hereof through April 16, 2003 (the "Accrued Interest Payment Date"), but such
accrued interest shall not be payable until the Accrued Interest Payment Date.
Thereafter, interest shall accrue at the Interest Rate and be payable on the
first business day (the "Payment Date") of each succeeding quarter through and
including April 16, 2006 (each such payment date being referred to herein as a
"Payment Date"). All principal, accrued but unpaid interest and any other
amounts due hereunder shall be due and payable at maturity on April 16, 2006.

         (b)(1) The Company shall pay the accrued interest on the Accrued
Interest Payment Date and shall pay all other interest thereafter accrued, at
the Company's option, in (i) cash in lawful money of United States of America,
(ii) common stock of the Company ("Company Common Stock") or (iii) a combination
of both cash and Company Common Stock. Any amounts remaining unpaid on this
Debenture on the maturity date hereof, whether principal, interest or other
amounts due hereunder, shall be paid in full in cash on such date. Any Company
Common Stock delivered to the Holder in payment of this Debenture as described
above will be valued at $0.25 per share ("Valuation Price"). The Company Common
Stock is listed on the OTC Bulletin Board and the Company shall take all
reasonable steps to maintain such listing. Such Valuation Price shall be
equitably adjusted in the case of a Corporate Event (as hereinafter defined) in
the manner provided in paragraph (d) below.

         (b)(2) The Company hereby grants to the Holders an option pursuant to
which the Holders will have the right, but not the obligation, to elect, until
the third (3rd) anniversary of the date of this Debenture, to convert any or all
of the principal amount of this Debenture into shares of Company Common Stock at
a conversion price of $0.125 per share (the "Conversion Price"), exercisable by
written notice to the Company. Such Conversion Price shall be equitably adjusted
in the case of a Corporate Event (as hereinafter defined) in the manner provided
in paragraph (d) below.

         (c) In order to make any payments on this Debenture in Company Common
Stock as described above, the Company will take, until the date on which all
principal and interest on this Debenture is fully repaid, all actions necessary
or appropriate to reserve for issuance that number of shares of Company Common
Stock sufficient to permit the Company to fulfill its obligations under this
Debenture. If the Holders elects to (i) have the Company pay any portion of
accrued interest (as provided in subsection (b)(1) above), principal (upon
conversion) as provided for in subsection (b)(2) above on this Debenture or (ii)
exercise the Warrants (as defined below) by delivering shares of Company Common
Stock to the Holders, the Company shall promptly take all steps required to
cause the Holders to be issued a sufficient number of shares of Company Common
Stock.

         (d) If, at any time after the date hereof and prior to the date on
which all principal and interest on this Debenture is paid in full, the Company
effects a dividend or other distribution upon or in redemption of Company Common
Stock payable in Company Common Stock, other securities or other property, a
combination of outstanding shares of Company Common Stock into a smaller number
of shares



                                      -2-
<PAGE>


of Company Common Stock, or any reorganization, split, exchange or
reclassification of Company Common Stock, or any consolidation or merger of the
Company with another corporation, or the sale of all or substantially all of its
assets to another corporation, in such a way that holders of outstanding Company
Common Stock shall be entitled to receive (either directly, or upon subsequent
liquidation) stock, securities or other property with respect to or in exchange
for Company Common Stock (any such event described in the foregoing clauses
being referred to as a "Corporate Event"), then as a condition of such Corporate
Event, lawful, appropriate, equitable and adequate provisions shall be made to
the terms of paragraphs (b) and (c) above whereby the Holders shall thereafter
be entitled to receive on each Payment Date (or, if applicable, the Accrued
Interest Payment Date) (under the same terms otherwise applicable to its receipt
of Company Common Stock), in lieu of or in addition to, as the case may be, the
payments specified in paragraphs (b) and (c) above, such cash, stock, securities
or other property which, when valued in a fair and equitable manner consistent
with the purposes and intent of this Debenture and when added to the amounts
being paid or Company Common Stock being issued on such Payment Date (or, if
applicable, the Accrued Interest Payment Date), discharges the full amount of
the accrued interest and principal (with respect to the maturity date hereof)
due on such date.

          (e) All payments due hereunder, whether made in the form of cash or
delivery of Company Common Stock, shall be made to each Holder's address for
notices set forth below or at such other place as the Holders may designate to
the Company in writing.



Section 3.                VOLUNTARY PREPAYMENT.


         The Company may prepay this Debenture in full or in part at any time,
provided that any such prepayment must be made in cash, unless otherwise agreed
to by the Holders. Early payments under this Debenture shall not relieve the
Company of its obligation to continue to make regularly scheduled payments as
required herein, but shall instead reduce the principal balance due, and the
Company may be required to make fewer payments under this Debenture.



Section 4.                GRANT OF SECURITY INTEREST


         The Company hereby grants to the Holders a first priority and perfected
security interest in and to all of the assets of the Company, including without

the foregoing, including without limitation, UCC-1 financing statements.

Section 6.                REGISTRATION RIGHTS

          (a) At the Company's sole expense (except for underwriting discounts
and commissions) the Company agrees to take all reasonable actions (including
preparing and filing with the SEC a registration statement (the "Registration
Statement") on an annual basis and the prospectus forming a part thereof) as may
be necessary to have such registration statement declared effective by the SEC
at the earliest date practicable and to keep such registration statement
effective, and to comply with the provisions of the Securities Act of 1933 (the
"Securities Act") and all applicable rules and regulations promulgated
thereunder in order to permit the Holders during such period to resell or
otherwise dispose of all of their Registered Shares (as defined below), without
further registration of the Registered Shares under the Securities Act; provided
that, before filing any such amendment or supplement, the Company will furnish
the Holders with copies of all such documents proposed to be filed and will
consider in good faith any written comments or suggested changes thereto made by
counsel designated by the Holders. Without limiting the generality of the
foregoing, the Company shall amend or supplement the Registration Statement to
increase the number of shares subject to resale by the Holders thereunder in the
event that the number of Registered Shares exceeds the number disclosed
thereunder as being available for resale by the Holders. "Registered Shares"
means all shares of Company Common Stock acquired by the Holders pursuant to the
terms of this Debenture (1) exercise of the conversion option by the Holders
with respect to the principal of this Debenture, (2) the Company's election to
pay accrued interest in the form of shares of Company Common Stock or (3) upon
exercise of the Warrants.

         (b) Following any resale by the Holders of Registered Shares pursuant
to the Registration Statement, the Holders shall notify the Company of the
number of Registered Shares sold and the date thereof. Nothing herein shall be
deemed to require the Holders to notify the Company of any sale of Registered
Shares pursuant to Rule 144 and Regulations promulgated under the Securities
Act, an exemption from the registration requirements of the Securities Act or
any other means (other than pursuant to the Registration Statement).

         (c) The Company agrees to take all other reasonable steps to ensure
that the Holder's resale of Registered Shares under the Registration Statement
is effected in accordance with the Securities Act and the regulations
promulgated thereunder, including:

                  (i) promptly filing all Exchange Act Reports as may be
         necessary to update the information relating to the Company included in
         the Registration Statement;

                  (ii) promptly furnishing to the Holders such number of copies
         of such Registration Statement, each amendment and supplement thereto,
         the prospectus included in such Registration Statement and such other
         documents as the Holders may reasonably request in order to facilitate
         the disposition of Registered Shares;

                  (iii) using its reasonable efforts to register or qualify the
         resales under state securities or "blue sky" laws and taking any and
         all other acts that may be necessary or advisable to enable the Holders
         to consummate such resales in such jurisdictions, provided however,
         that the Company will not be required to qualify generally to do
         business in any jurisdiction where it would not otherwise be required
         to qualify but for this subparagraph or subject itself to taxation in
         any such jurisdiction; notifying the Holders, at any time when a
         prospectus relating thereto is required to be delivered by the Holders
         under the Securities Act in connection with a resale of Registered
         Shares, of the occurrence of any event as a result of which the
         prospectus included in the Registration Statement contains an untrue
         statement of a material fact or omits any fact necessary to make the
         statements therein not misleading, and, at the request of the Holders,
         preparing a supplement or amendment to such prospectus or file an
         Exchange Act Report so that, as thereafter delivered to the purchasers
         of such stock, such prospectus will not contain an untrue statement of
         a material fact or omit to state any fact necessary to make the
         statements therein not misleading;



                                      -5-
<PAGE>


                  (iv) otherwise using its reasonable commercial efforts to
         comply with all applicable rules and regulations of the SEC; and

                  (v) in the event of the issuance of any stop order suspending
         the effectiveness of the Registration Statement, or of any order
         suspending or preventing the use of any related prospectus or
         suspending the qualification of any Company Common Stock registered
         under such Registration Statement for sale in any jurisdiction, using
         its reasonable commercial efforts promptly to obtain the withdrawal of
         such order.



Section 7.                MERGER.

         Notwithstanding any provision herein to the contrary, the Company shall
not consolidate or merge into or with any other person unless such person
expressly assumes all of the obligations of the Company under this Debenture.

evidenced, of the Company occur or exist.

Section 10.                WAIVERS.


         The Company hereby waives presentment for payment, protest, notice of
protest and notice of nonpayment. The Company agrees that the Holders acceptance
of payment other than in accordance with the terms of this Debenture, or the
Holders subsequent agreement to extend or modify such repayment terms, or the
Holder's failure or delay in exercising any rights or remedies granted to the
Holders, shall not have the effect of releasing the Company from its obligations
to the Holders. In addition, any failure or delay on the part of the Holders to

forbearance on the part of the Holders as to one event of default shall not be
construed as a waiver or forbearance as to any other event of default.
