        This  Debenture  is  issued  by  RUBBER   TECHNOLOGY   INC.,  a  Florida
corporation (the "COMPANY"), to ____________________________  (together with its
permitted  successors  and assigns,  the "HOLDER")  pursuant to exemptions  from
registration under the Securities Act of 1933, as amended.

                                   ARTICLE I.

        Section 1.01 PRINCIPAL AND INTEREST.  For value received,  on March ___,
2001,  the Company  hereby  promises to pay to the order of the Holder in lawful
money of the United  States of America and in  immediately  available  funds the
principal sum of __________________(US $________), together with interest on the
unpaid  principal  of this  Debenture  at the rate of five percent (5%) per year
(computed on the basis of a 365-day year and the actual days  elapsed)  from the
date of this Debenture until paid. At the Company's option, the entire principal
amount and all  accrued  interest  shall be either (a) paid to the Holder on the
second (2) year  anniversary from the date hereof or (b) converted in accordance
with Section 4.02 herein.

<PAGE>


        Section 1.02 OPTIONAL CONVERSION. The Holder is entitled, at its option,
to  convert  at any time and from time to time,  until  payment  in full of this
Debenture,  all or any  part of the  principal  amount  of the  Debenture,  plus
accrued interest,  into shares (the "CONVERSION Shares") of the Company's common
stock,  $0.0001  par  value  ("COMMON  STOCK"),  at the  price  per  share  (the
"CONVERSION  PRICE")  equal to either (a) an amount equal to one hundred  twenty
percent  (120%)  of the  closing  bid price of the  Common  Stock as listed on a
Principal Market (as defined herein),  as quoted by Bloomberg L.P. (the "CLOSING
BID  PRICE") as of the date  hereof,  or (b) an amount  equal to eighty  percent
(80%) of the average five (5) Closing Bid Prices of the Common Stock for the ten
(10) trading days immediately preceding the Conversion Date (as defined herein).
Subparagraphs  (a) and (b) above are  individually  referred to as a "CONVERSION
PRICE". As used herein,  "PRINCIPAL MARKET" shall mean the Nasdaq Bulletin Board
System,  Nasdaq SmallCap Market, or American Stock Exchange. If the Common Stock
is not traded on a Principal  Market,  the  Closing  Bid Price  shall mean,  the
reported  Closing Bid Price for the Common  Stock,  as furnished by the National
Association of Securities Dealers, Inc., for the applicable periods. No fraction
of  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. To convert this Debenture,  the Holder hereof shall deliver written
notice thereof, substantially in the form of EXHIBIT "A" to this Debenture, with
appropriate  insertions (the "CONVERSION NOTICE"), to the Company at its address
as set forth herein.  The date upon which the conversion shall be effective (the
"CONVERSION  DATE")  shall be deemed to be the date set forth in the  Conversion
Notice,  provided that the Company or the transfer agent delivers the Conversion
Shares within ten (10) business  days after receipt of a Conversion  Notice.  If
such  Conversion  Shares are not  delivered  within such ten (10)  business  day
period, the Conversion Date shall be the date such shares are actually delivered
to the Holder.

        Section 1.03  RESERVATION OF COMMON STOCK. The Company shall reserve and
keep available out of its authorized but unissued shares of Common Stock, solely
for the purpose of effecting the  conversion of this  Debenture,  such number of
shares of Common Stock as shall from time to time be  sufficient  to effect such
conversion, based upon the Conversion Price. If at any time the Company does not
have a sufficient number of Conversion Shares authorized and available, then the
Company shall call and hold a special meeting of its  stockholders  within sixty
(60)  days of that  time  for the sole  purpose  of  increasing  the  number  of
authorized shares of Common Stock.

        Section 1.04 REGISTRATION  RIGHTS.  The Company is obligated to register
the  resale of the  Conversion  Shares  under  the  Securities  Act of 1933,  as
amended,  pursuant to the terms of a Registration Rights Agreement,  between the
Company  and  the  Holder  of  even  date  herewith  (the  "REGISTRATION  RIGHTS
AGREEMENT").

        Section 1.05 INTEREST PAYMENTS.  The interest so payable will be paid at
the time of maturity or conversion to the person in whose name this Debenture is
registered.  At the time such  interest is  payable,  the  Company,  in its sole
discretion,  may elect to pay  interest in cash (via wire  transfer or certified
funds) or in the form of Common Stock. In the event of default,  as described in
Article III Section  3.01  hereunder,  the Holder may elect that the interest be
paid in cash (via wire  transfer  or  certified  funds) or in the form of Common
Stock.  If paid in the form of Common  Stock,  the  amount of stock to be issued
will be calculated  as follows:  the value of the stock shall be the Closing Bid
Price on: (i)  the  date the  interest payment  is  due; or (ii) if the interest



                                       2
<PAGE>

payment is not made when due, the date the interest payment is made. A number of
shares of Common Stock with a value equal to the amount of interest due shall be
issued.  No fractional shares will be issued;  therefore,  in the event that the
value of the Common Stock per share does not equal the total  interest  due, the
Company will pay the balance in cash.

        Section 1.06 PAYING AGENT AND REGISTRAR. Initially, the Company will act
as paying  agent and  registrar.  The  Company  may  change  any  paying  agent,
registrar,  or  Company-registrar  by giving  the  Holder not less than ten (10)
business  days' written  notice of its election to do so,  specifying  the name,
address, telephone number and facsimile number of the paying agent or registrar.
The Company may act in any such capacity.

        Section 1.07  SUBORDINATED  NATURE OF DEBENTURE.  This Debenture and all
payments  hereon,  including  principal or interest,  shall be  subordinate  and
junior in right of payment to all  accounts  payable of the Company  incurred in
the  ordinary  course of business  and/or bank debt of the Company not to exceed
$500,000.

                                  ARTICLE II.

        Section 2.01  AMENDMENTS  AND WAIVER OF DEFAULT.  The  Debenture  may be
amended with the consent of the Holder.  Without the consent of the Holder,  the
Debenture  may be amended to cure any  ambiguity,  defect or  inconsistency,  to
provide for  assumption of the Company  obligations to the Holder or to make any
change that does not adversely affect the rights of the Holder.

                                  ARTICLE III.

        Section  3.01  EVENTS OF  DEFAULT.  An Event of  Default  is  defined as
follows:  (a) failure by the Company to pay amounts due hereunder within fifteen
(15) business days of the date of maturity of this Debenture; (b) failure by the
Company to advise its transfer  agent to issue Common Stock to the Holder within
ten (10)  business  days of the  Company's  receipt  of the  attached  Notice of
Conversion from Holder; (c) failure by the Company for thirty (30) business days
after notice to it to comply with any of its other  agreements in the Debenture;
(d)  events of  bankruptcy  or  insolvency;  (e) a breach by the  Company of its
obligations  under the  Registration  Rights Agreement which is not cured by the
Company  within  fifteen  (15)  business  days after  receipt of written  notice
thereof. The Holder may not enforce the Debenture except as provided herein.

        Section 3.02 FAILURE TO ISSUE UNRESTRICTED COMMON STOCK. As indicated in
Article III Section 3.01, a breach by the Company of its  obligations  under the
Registration Rights Agreement shall be deemed an Event of Default,  which if not
cured within ten (10) days, shall entitle the Holder  accelerated full repayment
of all debentures outstanding.  The Company acknowledges that failure to honor a
Notice of Conversion shall cause hardship to the Holder.

                                  ARTICLE IV.

Section  4.01 RIGHTS AND TERMS OF  CONVERSION.  This  Debenture,  in whole or in
part, may be converted at any time following the date of closing, into shares of
Common  Stock at a price equal to the  Conversion  Price as described in Section
1.02 above.

        Section 4.02 RE-ISSUANCE OF DEBENTURE. When the Holder elects to convert
a part of the  Debenture,  then the Company shall reissue a new Debenture in the
same form as this Debenture to reflect the new principal amount.

        Section 4.03 LIMITATION ON RIGHT AND POWER TO EXERCISE. Any provision in
this  Debenture  or any other  document to the contrary  not  withstanding,  the
Holder shall not have the right or power to convert this  Debenture  into Common
Stock,  either in whole or in part,  and any attempt to do so shall be void, if,
after having given  effect to such  conversion,  the Holder shall be or shall be
deemed  to be the  beneficial  owner  of ten  percent  (10%) or more of the then
outstanding Common Stock within the meaning or for the purposes of Section 13(d)
or 13(g) of the  Securities  Exchange  Act of 1934,  as amended  (the  "EXCHANGE
ACT"), or as the term "BENEFICIAL OWNER" is defined in Rule 13d-3 of the Act.

        Section 4.04  TERMINATION  OF CONVERSION  RIGHTS.  The Holder's right to
convert the Debenture  into the Common Stock in accordance  with  paragraph 4.01
shall terminate on the date that is the two (2) year  anniversary  from the date
hereof  and this  Debenture  shall be  automatically  converted  on that date in
accordance  with  the  formula  set  forth  in  Section  4.01  hereof,  and  the
appropriate shares of Common Stock and amount of interest shall be issued to the
Holder.

                                   ARTICLE V.

        Section 5.01  ANTI-DILUTION.  In the event that the Company shall at any
time subdivide the  outstanding  shares of Common Stock,  or shall issue a stock
dividend  on the  outstanding  Common  Stock,  the  Conversion  Price in  effect
immediately  prior to such subdivision or the issuance of such dividend shall be
proportionately  decreased,  and in the event that the Company shall at any time
combine the outstanding  shares of Common Stock,  the Conversion Price in effect
immediately  prior  to such  combination  shall  be  proportionately  increased,
effective at the close of business on the date of such subdivision,  dividend or
combination as the case may be.

        Section 5.02 CONSENT OF HOLDER TO SELL COMMON  STOCK.  So long as any of
the principal of or interest on this Note remains  unpaid and  unconverted,  the
Company shall not,  without the prior  consent of the Holder,  issue or sell (i)
any Common Stock without  consideration  or for a  consideration  per share less
than its fair market value determined immediately prior to its issuance, or (ii)
issue or sell any warrant,  option, right, contract,  call, or other security or
instrument granting the holder thereof the right to acquire Common Stock without
consideration  or for a  consideration  per share less than such Common  Stock's
fair market value determined immediately prior to its issuance.
