                        DEBENTURE DUE SEPTEMBER 21, 2002

            THIS DEBENTURE of Kenwick Industries, Inc., a corporation duly
organized and existing under the laws of Florida ("Company"), designated as its

Twenty-Five Thousand Dollars (U.S.$225,000), which Debentures are being
purchased at 100% of the face amount of such Debentures.

            FOR VALUE RECEIVED, the Company promises to pay to M&B Trading,
L.L.C. the registered holder hereof and his authorized successors and permitted
assigns ("Holder"), the aggregate principal face sum not to exceed Two Hundred
Twenty-Five Thousand Dollars (U.S. $225,000) on September 21, 2002 ("Maturity

made or duly provided for. The interest so payable will be paid to the person in
whose name this Debenture is registered on the records of the Company regarding
registration and transfers of the Debentures ("Debenture Register"); provided,
however, that the Company's obligation to a transferee of this Debenture arises
only if such transfer, sale or other disposition is made in accordance with the
terms and conditions of the Securities Subscription Agreement dated as of
September 21, 1999 between the Company and M&B Trading, L.L.C. ("Subscription
Agreement"). The principal of, and interest on, this Debenture are payable at
the address last appearing on the Debenture Register
<PAGE>

Register of the Company as designated in writing by the Holder hereof from time
to time. The Company will pay the outstanding principal due upon this Debenture
before or on the Maturity Date, less any amounts required by law to be deducted
or withheld, to the Holder of this Debenture by check if paid more than 10 days
prior to the Maturity Date or by wire transfer and addressed to such Holder at
the last address appearing on the Debenture Register. The forwarding of such
check or wire transfer shall constitute a payment of outstanding principal
hereunder and shall satisfy and discharge the liability for principal on this
Debenture to the extent of the sum represented by such check or wire transfer.
Interest shall be payable in Common Stock (as defined below) pursuant to
paragraph 4(b) herein.

            This Debenture is subject to the following additional provisions:

            1. The Debentures are issuable in denominations of Ten Thousand
Dollars (US$10,000) and integral multiples thereof. The Debentures are
exchangeable for an equal aggregate principal amount of Debentures of different
authorized denominations, as requested by the Holders surrendering the same, but
not less than U.S. $10,000. No service charge will be made for such registration
or transfer or exchange, except that Holder shall pay any tax or other
governmental charges payable in connection therewith.

            2. The Company shall be entitled to withhold from all payments any
amounts required to be withheld under the applicable laws.

            3. This Debenture may be transferred or exchanged only in compliance
with the Securities Act of 1933, as amended ("Act") and applicable state
securities laws. Prior to due presentment for transfer of this Debenture, the
Company and any agent of the Company may treat the person in whose name this
Debenture is duly registered on the Company's Debenture Register as the owner
hereof for all other purposes, whether or not this Debenture be overdue, and
neither the Company nor any such agent shall be affected or bound by notice to
the contrary. Any Holder of this Debenture, electing to exercise the right of
conversion set forth in Section 4(a) hereof, in addition to the requirements set
forth in Section 4(a), and any prospective transferee of this Debenture, are
also required to give the Company written confirmation that the Debenture is
being converted ("Notice of Conversion") in the form annexed hereto as Exhibit
I.

            4. (a) The Holder of this Debenture is entitled, at its option, at
any time immediately following execution of this Agreement and delivery of the
Debenture hereof, to convert all or any amount over $10,000 of the principal
face amount of this Debenture then outstanding into shares of Common Stock,
$0.01 par value per share, of the Company freely tradeable and without
restrictive legend of any kind ("Common Stock"), at a conversion price
("Conversion Price") for each share of Common Stock equal to 77.5% of the
average closing bid price of the Common Stock as reported on the National
Association of Securities Dealers Electronic Bulletin Board ("OTC-Bulletin
Board") for the three (3) consecutive trading days immediately preceding the
date of receipt by the Company of Notice of Conversion ("Conversion Shares"). If
the number of resultant


                                       -2-
<PAGE>

Conversion Shares would as a matter of law or pursuant to regulatory authority
require the Company to seek shareholder approval of such issuance, the Company
shall, as soon as practicable, take the necessary steps to seek such approval.
Such conversion shall be effectuated, as provided in a certain Escrow Agreement
executed simultaneously with this Debenture, by the Company delivering the
Conversion Shares to the Holder within 5 business days of receipt by the Company
of the Notice of Conversion. Once the Holder has received such Conversion
Shares, the Escrow Agent shall surrender the Debentures to be converted to the
Company, executed by the Holder of this Debenture evidencing such Holder's
intention to convert this Debenture or a specified portion hereof, and
accompanied by proper assignment hereof in blank. Accrued but unpaid interest
shall be subject to conversion. No fractional shares or scrip representing
fractions of shares will be issued on conversion, but the number of shares
issuable shall be rounded to the nearest whole share.

            (b) Interest at the rate of 8% per annum shall be paid by issuing
Common Stock of the Company as follows: Based on the average closing bid price
of the Common Stock for three (3) consecutive trading days immediately preceding
the date of the monthly interest payment due as reported on the OTC-Bulletin
Board ("Market Price"), the Company shall issue to the Holder shares of Common
Stock in an amount equal to the total monthly interest accrued and due divided
by 77.5% of the Market Price ("Interest Shares"). The dollar amount of interest
payable pursuant to this paragraph 4(b) shall be calculated based upon the total
amount of payments actually made by the Holder in connection with the purchase
of the Debentures at the time any interest payment is due. If such payment is
made by check, interest shall accrue beginning 10 day's from the date the check
is received by the Company. If such payment is made by wire transfer directly
into the Company's account, interest shall accrue beginning on the date the wire
transfer is received by the Company. Common Stock issued pursuant hereto shall
be issued pursuant to Rule 504 of Regulation D in accordance with the terms of
the Subscription Agreement and shall be freely tradeable and without restrictive
legend of any kind.

            (c) At any time after 90 day's the Company shall have the option to
pay to the Holder 122.5% of the principal amount of the Debenture, in full, to
the extent conversion has not occurred pursuant to paragraph 4(a) herein, or pay
upon maturity if the Debenture is not converted. The Company shall give the
Holder 5 days written notice and the Holder during such 5 day's shall have the
option to convert the Debenture or any part thereof into shares of Common Stock
at the Conversion Price set forth in paragraph 4(a) of this Debenture.

            5. No provision of this Debenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of, and interest on, this Debenture at the time, place, and rate, and
in the form, herein prescribed.

            6. The Company hereby expressly waives demand and presentment for
payment, notice of non-payment, protest, notice of protest, notice of dishonor,
notice of acceleration or intent to accelerate, and diligence in taking any
action to collect amounts called for hereunder and shall be directly and
primarily liable for the payment of all sums owing and to be owing hereto.


                                       -3-
<PAGE>

            7. The Company agrees to pay all costs and expenses, including
reasonable attorneys' fees, which may be incurred by the Holder in collecting
any amount due under this Debenture.

            8. If one or more of the following described "Events of Default"
shall occur and continue for 30 day's, unless a different time frame is noted
below:

            (a)   The Company shall default in the payment of principal or

                  the Subscription Agreement or the Escrow Agreement and such

                  of such petition or have filed against it an involuntary
                  petition for bankruptcy relief, all under federal or state

            (e)   A trustee, liquidator or receiver shall be appointed for the
                  Company or for a substantial part of its property or business
                  without its consent and shall not be discharged within thirty
                  (30) days after such appointment; or

            (f)   Any governmental agency or any court of competent jurisdiction
                  at the instance of any governmental agency shall assume
                  custody or control of the whole or any substantial portion of
                  the properties or assets of the Company; or


                                       -4-
<PAGE>

            (g)   Any money judgment, writ or warrant of attachment, or similar
                  process, in excess of One Hundred Thousand ($100,000) Dollars

            (h)   Bankruptcy, reorganization, insolvency or liquidation

            (i)   The Company shall have its Common Stock delisted from the

Then, or at any time thereafter, unless cured, and in each and every such case,
unless such Event of Default shall have been waived in writing by the Holder
(which waiver shall not be deemed to be a waiver of any subsequent default) at
the option of the Holder and in the Holder's sole discretion, the Holder may
consider this Debenture immediately due and payable, without presentment,
demand, protest or (further) notice of any kind (other than notice of
acceleration), all of which are hereby expressly waived, anything herein or in
any note or other instruments contained to the contrary notwithstanding, and the
Holder may immediately, and without expiration of any period of grace, enforce
any and all of the Holder's rights and remedies provided herein or any other
rights or remedies afforded by law.

            9. This Debenture represents a prioritized obligation of the
Company. However, no recourse shall be had for the payment of the principal of,
or the interest on, this Debenture, or for any claim based hereon, or otherwise
in respect hereof, against any incorporator, shareholder, officer or director,
as such, past, present or future, of the Company or any successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

            10. In case any provision of this Debenture is held by a court of
competent jurisdiction to be excessive in scope or otherwise invalid or
unenforceable, such provision shall be adjusted rather than voided, if possible,
so that it is enforceable to the maximum extent possible, and


                                       -5-
<PAGE>

the validity and enforceability of the remaining provisions of this Debenture
will not in any way be affected or impaired thereby.

            11. This Debenture and the agreements referred to in this Debenture
constitute the full and entire understanding and agreement between the Company
and the Holder with respect to the subject hereof. Neither this Debenture nor
any term hereof may be amended, waived, discharged or terminated other than by a
written instrument signed by the Company and the Holder.

            12. This Debenture shall be governed by and construed in accordance
with the laws of Colorado applicable to contracts made and wholly to be
performed within the State of Colorado and shall be binding upon the successors
and assigns of each party hereto. The Holder and the Company hereby mutually
waive trial by jury and consent to exclusive jurisdiction and venue in the
courts of the State of Colorado. At Holder's election, any dispute between the
parties may be arbitrated rather than litigated in the courts, before the
American Arbitration Association in Denver and pursuant to its rules. Upon
demand made by the Holder to the Company, the Company agrees to submit to and
participate in such arbitration. This Agreement may be executed in counterparts,
and the facsimile transmission of an executed counterpart to this Agreement
shall be effective as an original.

            IN WITNESS WHEREOF, the Company has caused this instrument to be
duly executed by an officer thereunto duly authorized.
