                        DUE TWELVE MONTHS FROM ISSUANCE

     THIS DEBENTURE is one of a series of duly authorized and issued debentures
of Aquatic Cellulose International Corporation, a Nevada corporation, having a
principal place of business at 3704 32/nd/ Street, Suite 301, Vernon, B.C.,
Canada VIT 5N6 (the "Company"), designated as its 12% Convertible Debentures,
                     -------
due twelve months from issuance, in the aggregate principal amount of Four
Hundred and Fifty Thousand Dollars ($450,000) (the "Debentures").  All
                                                    ----------
references to $ (dollars) shall be to US$ (United States dollars).

     FOR VALUE RECEIVED, the Company promises to pay to New Millennium Capital
Partners II, LLC, or its registered assigns (the "Holder"), the principal sum of
                                                  ------
$50,000, on March 14, 2002 or such earlier date as the Debentures are required
or permitted to be repaid as provided hereunder (the "Maturity Date") and to pay
                                                      -------------
interest to the Holder on the aggregate unconverted and then outstanding
principal amount of this Debenture at the rate of 12% per annum, payable on a
quarterly basis on March 31, June 30, September 30 and December 31 of each year
while this Debenture is outstanding (each, an "Interest Payment Date") and on
                                               ---------------------
each Conversion Date (as defined herein)for such principal amount, commencing on
the earlier to occur of a Conversion Date for such principal amount and March
31, 2001, in cash or shares of Common Stock (as defined in Section 6).  Subject
to the terms and conditions herein, the Holder may elect to receive interest
hereunder in shares of Common Stock or cash.  If interest is paid by the Company
in shares of its Common Stock, then the number of shares of Common Stock
issuable on account of  such interest shall equal the cash amount of such
interest on such Interest Payment Date divided by the Conversion Price (as
defined below) on such date.  Interest shall be calculated on the basis on a
360-day year and shall accrue daily commencing on the Original
<PAGE>

Issue Date (as defined in Section 6) until payment in full of the principal sum,
together with all accrued and unpaid interest and other amounts which may become
due hereunder, has been made. Interest hereunder will be paid to the Person (as
defined in Section 6) in whose name this Debenture is registered on the records
of the Company regarding registration and transfers of Debentures (the

 ------------------
cash hereunder shall entail a late fee at the rate of 15% per annum (or such
lower maximum amount of interest permitted to be charged under applicable law)
("Late Fee") (which will accrue daily, from the date such interest is due
  --------
hereunder through and including the date of payment), payable in cash or, at the
option of the Holder, in shares of Common Stock. If such Late Fee is paid by the
Company in shares of its Common Stock, then the number of shares of Common Stock
issuable on account of such Late Fee shall equal the cash amount of such Late
Fee on such Late Fee payment date divided by the Conversion Price on such date.

     This Debenture is subject to the following additional provisions:

     Section 1.  This Debenture is exchangeable for an equal aggregate principal
     ----------
amount of Debentures of different authorized denominations, as requested by the

transfer of this Debenture, the Company and any agent of the Company may treat
the Person (as defined in Section 6) in whose name this Debenture is duly
registered on the Debenture Register as the owner hereof for the purpose of

rescinded and annulled by Holder at any time prior to payment hereunder and the
Holder shall have all rights as a Debenture Holder until such time, if any, as
the full payment under this Section shall have been received by it. No such
rescission or annulment shall affect any subsequent Event of Default or impair
any right consequent thereon.

     Section 4.  Conversion.
     ----------  ----------

            (a)  (i)  Conversion at Option of Holder. (A) This Debenture shall
                      ------------------------------
be convertible into shares of Common Stock  at the option of the Holder, in
whole or in part at any time and from time to time, after the Original Issue
Date (subject to the limitations on conversion set forth in Section 4(a)(ii)
hereof).   The number of shares of Common Stock  issuable upon a conversion
hereunder equals the sum of (i) the quotient obtained by dividing (x) the
outstanding principal amount of this Debenture to be converted by (y) the
Conversion Price (as defined herein), and (ii) the amount equal to (I) the
product of (x) the outstanding principal amount of this Debenture to be
converted and (y) the product of (1) the quotient obtained by dividing .12 by
360 and (2) the number of days for which such principal amount was outstanding,
divided by (II) the Conversion Price on the Conversion Date, provided, that if
                                                             --------
the Holder shall have elected to receive the interest due on a Conversion Date
in cash, subsection (ii) shall not be used in the calculation of the number of
shares of Common Stock  issuable upon a conversion hereunder.

                 (B)  The Holder shall effect conversions by delivering to the
Company a completed notice in the form attached hereto as Exhibit A (a
                                                          ---------
"Conversion Notice") including a completed Conversion Schedule in the form of
 -----------------
Schedule 1 to the Conversion Notice (on each Conversion Date, the "Conversion
----------                                                         ----------
Schedule"). The Conversion Schedule shall set forth the remaining principal
--------
amount of this Debenture and all accrued and unpaid interest thereon subsequent
to the conversion at issue. The date on which a Conversion Notice is delivered
is the "Conversion Date." Unless the Holder is converting the entire principal
        ---------------
amount outstanding under this Debenture, the Holder is not be required to
physically surrender this Debenture to the Company in order to effect
conversions. Subject to Section 4(b), each Conversion Notice, once given, shall
be irrevocable. Conversions hereunder shall have the effect of lowering the
outstanding principal amount of this Debenture plus all accrued and unpaid
interest thereon in an amount equal to the applicable conversion, which shall be
evidenced by entries set forth in the Conversion Schedule. The Holder and the
Company shall maintain records showing the principal amount converted and the
date of such conversions. In the event of any dispute or discrepancy, the
records of the Holder shall be controlling and determinative in the absence of
manifest error.

                 (ii) Certain Conversion Restrictions.
                      --------------------------------

                                      -9-
<PAGE>

                    (A) A Holder may not convert Debentures or receive shares of
Common Stock as payment of interest hereunder to the extent such conversion or
receipt of such interest payment would result in the Holder, together with any
affiliate thereof, beneficially owning (as determined in accordance with Section
13(d) of the Exchange Act and the rules promulgated thereunder) in excess of
4.999% of the then issued and outstanding shares of Common Stock, including
shares issuable upon conversion of, and payment of interest on, the Debentures
held by such Holder after application of this Section. Since the Holder will not
be obligated to report to the Company the number of shares of Common Stock it
may hold at the time of a conversion hereunder, unless the conversion at issue
would result in the issuance of shares of Common Stock in excess of 4.999% of
the then outstanding shares of Common Stock without regard to any other shares
which may be beneficially owned by the Holder or an affiliate thereof, the
Holder shall have the authority and obligation to determine whether the
restriction contained in this Section will limit any particular conversion
hereunder and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which portion of the
principal amount of Debentures are convertible shall be the responsibility and
obligation of the Holder. If the Holder has delivered a Conversion Notice for a
principal amount of Debentures that, without regard to any other shares that the
Holder or its affiliates may beneficially own, would result in the issuance in
excess of the permitted amount hereunder, the Company shall notify the Holder of
this fact and shall honor the conversion for the maximum principal amount
permitted to be converted on such Conversion Date in accordance with the periods
described in Section 4(b) and, at the option of the Holder, either retain any
principal amount tendered for conversion in excess of the permitted amount
hereunder for future conversions or return such excess principal amount to the
Holder. The provisions of this Section may be waived by a Holder (but only as to
itself and not to any other Holder) upon not less than 61 days prior notice to
the Company. Other Holders shall be unaffected by any such waiver.

                    (B) A Holder may not convert Debentures or receive shares of
Common Stock as payment of interest hereunder to the extent such conversion or
receipt of such interest payment would result in the Holder, together with any
affiliate thereof, beneficially owning (as determined in accordance with Section
13(d) of the Exchange Act and the rules promulgated thereunder) in excess of
9.999% of the then issued and outstanding shares of Common Stock, including
shares issuable upon conversion of, and payment of interest on, the Debentures
held by such Holder after application of this Section. Since the Holder will not
be obligated to report to the Company the number of shares of Common Stock it
may hold at the time of a conversion hereunder, unless the conversion at issue
would result in the issuance of shares of Common Stock in excess of 9.999% of
the then outstanding shares of Common Stock without regard to any other shares
which may be beneficially owned by the Holder or an affiliate thereof, the
Holder shall have the authority and obligation to determine whether the
restriction contained in this Section will limit any particular conversion
hereunder and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which portion of the
principal amount of Debentures are convertible shall be the responsibility and
obligation of the Holder. If the Holder has delivered a Conversion Notice for a
principal amount of Debentures that, without regard to any other shares that the
Holder or its affiliates may beneficially own, would result in the issuance in
excess of the permitted amount hereunder, the Company shall notify the Holder of
this fact and shall honor the conversion for the maximum

                                     -10-
<PAGE>

principal amount permitted to be converted on such Conversion Date in accordance
with the periods described in Section 4(b) and, at the option of the Holder,
either retain any principal amount tendered for conversion in excess of the
permitted amount hereunder for future conversions or return such excess
principal amount to the Holder. The provisions of this Section may be waived by
a Holder (but only as to itself and not to any other Holder) upon not less than
61 days prior notice to the Company. Other Holders shall be unaffected by any
such waiver.

          (b)  (i)  Not later than three Trading Days after any Conversion Date,
the Company will deliver to the Holder (i) a certificate or certificates which
shall be free of restrictive legends and trading restrictions (other than those
required by Section 3.1(b) of the Purchase Agreement) representing the number of
shares of Common Stock issuable upon such conversion in accordance with the
terms hereof (subject to the limitations set forth in Section 4(a)(ii) hereof),
(ii) if the Holder has elected to receive accrued interest in cash, the Company
will deliver to the Holder a bank check, payable to Holder, in the amount of
accrued and unpaid interest. If requested by a Holder, the Company will use its
best efforts to deliver conversion shares electronically through the Depository
Trust Corporation or another established clearing corporation performing similar
functions. If shares of Common Stock issuable following a Conversion Notice are
not delivered to or as directed by the Holder by the third Trading Day after a
Conversion Date, the Holder shall be entitled by written notice to the Company
at any time on or before its receipt of such shares, to rescind such conversion,
in which event the Company shall immediately return to the Holder a Debenture in
principal amount equal to the principal amount, interest and all other amounts
due in respect of the Conversion Notice (provided the Holder is converting the
entire principal amount outstanding under this Debenture).

                    (ii)  If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 4(b)(i) by the third Trading Day
after the Conversion Date, the Company shall pay to such Holder, in cash, as
liquidated damages and not as a penalty, $2,500 for each Trading Day after such
third Trading Day until such certificates are delivered. Nothing herein shall
limit a Holder's right to pursue actual damages or declare an Event of Default
pursuant to Section 3 herein for the Company's failure to deliver certificates
representing shares of Common Stock upon conversion within the period specified
herein and such Holder shall have the right to pursue all remedies available to
it at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief. The exercise of any such rights shall not
prohibit the Holders from seeking to enforce damages pursuant to any other
Section hereof or under applicable law. Further, if the Company shall not have
delivered any cash due in respect of conversions of Debentures or as payment of
interest thereon by the third Trading Day after the Conversion Date, the Holder
may, by notice to the Company, require the Company to issue shares of Common
Stock pursuant to Section 4(c), except that for such purpose the Conversion
Price applicable thereto shall be the lesser of the Conversion Price on the
Conversion Date and the Conversion Price on the date of such Holder demand. Any
such shares will be subject to the provision of this Section.

                    (iii) In addition to any other rights available to the
Holder, if the Company fails for any reason to deliver to the Holder such
certificate or certificates pursuant to

                                     -11-
<PAGE>

Section 4(b)(i) by the third Trading Day after the Conversion Date, and if after
such third Trading Day the Holder purchases (in an open market transaction or
otherwise) Common Stock to deliver in satisfaction of a sale by such Holder of
the Underlying Shares which the Holder anticipated receiving upon such
conversion (a "Buy-In"), then the Company shall (A) pay in cash to the Holder
               ------
(in addition to any remedies available to or elected by the Holder) the amount
by which (x) the Holder's total purchase price (including brokerage commissions,
if any) for the Common Stock so purchased exceeds (y) the product of (1) the
aggregate number of shares of Common Stock that such Holder anticipated
receiving from the conversion at issue multiplied by (2) the market price of the
Common Stock at the time of the sale giving rise to such purchase obligation and
(B) at the option of the Holder, either reissue Debentures in principal amount
equal to the principal amount of the attempted conversion or deliver to the
Holder the number of shares of Common Stock that would have been issued had the
Company timely complied with its delivery requirements under Section 4(b)(i).
For example, if the Holder purchases Common Stock having a total purchase price
of $11,000 to cover a Buy-In with respect to an attempted conversion of
Debentures with respect to which the market price of the Underlying Shares on
the date of conversion was a total of $10,000 under clause (A) of the
immediately preceding sentence, the Company shall be required to pay the Holder
$1,000. The Holder shall provide the Company written notice indicating the
amounts payable to the Holder in respect of the Buy-In. Notwithstanding anything
contained herein to the contrary, if a Holder requires the Company to make
payment in respect of a Buy-In for the failure to timely deliver certificates
hereunder and the Company timely pays in full such payment, the Company shall
not be required to pay such Holder liquidated damages under Section 4(b)(ii) in
respect of the certificates resulting in such Buy-In.

          (c)  (i)  The conversion price (the "Conversion Price") in effect on
                                               ----------------
any Conversion Date shall be the lesser of (1) $0.083 (the "Initial Conversion
                                                            ------------------
Price"), and (2) 66.67% of the average of the lowest three inter-day sales
-----
prices of the Common Stock (which need not occur on consecutive Trading Days but
which may not include prices that are sales by the Holder) during the twenty
Trading Days immediately preceding the applicable Conversion Date (which may
include Trading Days prior to the Original Issue Date), provided, that such
                                                        --------
twenty Trading Day period shall be extended for the number of Trading Days
during such period in which (A) trading in the Common Stock is suspended by the
OTC or a Subsequent Market on which the Common Stock is then listed, or (B)
after the date declared effective by the Commission, the Underlying Shares
Registration Statement is either not effective, the Prospectus included in the
Underlying Shares Registration Statement may not be used by the Holder for the
resale of Underlying Shares.

                    (ii) If the Company, at any time while the Debentures are
outstanding, (a) shall pay a stock dividend or otherwise make a distribution or
distributions on shares of its Common Stock or any other equity or equity
equivalent securities payable in shares of Common Stock, (b) subdivide
outstanding shares of Common Stock into a larger number of shares, (c) combine
(including by way of reverse stock split) outstanding shares of Common Stock
into a smaller number of shares, or (d) issue by reclassification of shares of
the Common Stock any shares of capital stock of the Company, then the Initial
Conversion Price shall be multiplied by a fraction of which the numerator shall
be the number of shares of Common Stock

                                     -12-
<PAGE>

(excluding treasury shares, if any) outstanding before such event and of which
the denominator shall be the number of shares of Common Stock outstanding after
such event. Any adjustment made pursuant to this Section shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such dividend or distribution and shall become effective immediately
after the effective date in the case of a subdivision, combination or re-
classification.

                    (iii) If the Company, at any time while the Debentures are
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to Holders) entitling them to subscribe for or purchase shares of
Common Stock at a price per share less than the Per Share Market Value at the
record date mentioned below, then the Conversion Price shall be multiplied by a
fraction, of which the denominator shall be the number of shares of the Common
Stock (excluding treasury shares, if any) outstanding on the date of issuance of
such rights or warrants plus the number of additional shares of Common Stock
offered for subscription or purchase, and of which the numerator shall be the
number of shares of the Common Stock (excluding treasury shares, if any)
outstanding on the date of issuance of such rights or warrants plus the number
of shares which the aggregate offering price of the total number of shares so
offered would purchase at such Per Share Market Value.  Such adjustment shall be
made whenever such rights or warrants are issued, and shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such rights, options or warrants.  However, upon the expiration of
any such right, option or warrant to purchase shares of the Common Stock the
issuance of which resulted in an adjustment in the Conversion Price pursuant to
this Section, if any such right, option or warrant shall expire and shall not
have been exercised, the Conversion Price shall immediately upon such expiration
be recomputed and effective immediately upon such expiration be increased to the
price which it would have been (but reflecting any other adjustments in the
Conversion Price made pursuant to the provisions of this Section after the
issuance of such rights or warrants) had the adjustment of the Conversion Price
made upon the issuance of such rights, options or warrants been made on the
basis of offering for subscription or purchase only that number of shares of the
Common Stock actually purchased upon the exercise of such rights, options or
warrants actually exercised.

                    (iv)  If the Company or any subsidiary thereof, as
applicable with respect to Common Stock Equivalents (as defined below), at any
time while Debentures are outstanding shall issue shares of Common Stock or
rights, warrants, options or other securities or debt that are convertible into
or exchangeable for shares of Common Stock ("Common Stock Equivalents"),
                                             ------------------------
entitling any Person to acquire shares of Common Stock at a price per share less
than the Conversion Price (if the holder of the Common Stock or Common Stock
Equivalent so issued shall at any time, whether by operation of purchase price
adjustments, reset provisions, floating conversion, exercise or exchange prices
or otherwise, or due to warranty options or rights per share which are issued in
connection with such issuance, be entitled to receive shares of Common Stock at
a price per share which is less than the Conversion Price, such issuance shall
be deemed to have occurred for less than the Conversion Price), then, at the
sole option of the Holder, the Conversion Price shall be adjusted to mirror the
conversion, exchange or purchase price for such Common Stock or Common Stock
Equivalents (including any reset provisions thereof) at issue. Such adjustment
shall be made whenever such Common Stock or

                                     -13-
<PAGE>

Common Stock Equivalents are issued. The Company shall notify the Holder and the
Escrow Agent in writing, no later than the business day following the issuance
of any Common Stock or Common Stock Equivalent subject to this section,
indicating therein the applicable issuance price, or of applicable reset price,
exchange price, conversion price and other pricing terms. No adjustment under
this Section shall be made as a result of (i) issuances of Common Stock or
Common Stock Equivalents to the extent disclosed in Schedule 2.1(c) to the
Purchase Agreement, (ii) issuances and exercises of options to purchase shares
of Common Stock issued for compensatory purposes pursuant to any of the
Company's stock option or stock purchase plans, or (iii) exercises under the
Warrants (as defined in the Purchase Agreement).

                    (v)   If the Company, at any time while Debentures are
outstanding, shall distribute to all holders of Common Stock (and not to
Holders) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security, then in each such case the Conversion
Price at which Debentures shall thereafter be convertible shall be determined by
multiplying the Conversion Price in effect immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by
a fraction of which the denominator shall be the Per Share Market Value
determined as of the record date mentioned above, and of which the numerator
shall be such Per Share Market Value on such record date less the then fair
market value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holders of the
portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

                    (vi)  In case of any reclassification of the Common Stock or
any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property, the Holders shall have the right
thereafter to, at their option, (A) convert the then outstanding principal
amount, together with all accrued but unpaid interest and any other amounts then
owing hereunder in respect of this Debenture only into the shares of stock and
other securities, cash and property receivable upon or deemed to be held by
holders of the Common Stock following such reclassification or share exchange,
and the Holders of the Debentures shall be entitled upon such event to receive
such amount of securities, cash or property as the shares of the Common Stock of
the Company into which the then outstanding principal amount, together with all
accrued but unpaid interest and any other amounts then owing hereunder in
respect of this Debenture could have been converted immediately prior to such
reclassification or share exchange would have been entitled or (B) require the
Company to prepay the aggregate of its outstanding principal amount of
Debentures, plus all interest and other amounts due and payable thereon, at a
price determined in accordance with Section 3(b). The entire prepayment price
shall be paid in cash. This provision shall similarly apply to successive
reclassifications or share exchanges.

                    (vii) All calculations under this Section 4 shall be made to
the nearest cent or the nearest 1/100th of a share, as the case may be.  No
adjustments in either the

                                     -14-
<PAGE>

Conversion Price or the Initial Conversion Price shall be required if such
adjustment is less than $0.01, provided, however, that any adjustments which by
                               --------
reason of this Section are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.

                    (viii) Whenever either the Initial Conversion Price or the
Conversion Price is adjusted pursuant to any of Section 4(c)(ii) - (v), the
Company shall promptly mail to each Holder a notice setting forth the Initial
Conversion Price or Conversion Price (as applicable) after such adjustment and
setting forth a brief statement of the facts requiring such adjustment.

                    (ix)   If (A) the Company shall declare a dividend (or any
other distribution) on the Common Stock; (B) the Company shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock; (C) the
Company shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any shares of capital stock of any
class or of any rights; (D) the approval of any stockholders of the Company
shall be required in connection with any reclassification of the Common Stock,
any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; (E) the Company shall authorize the voluntary or
involuntary dissolution, liquidation or winding up of the affairs of the
Company; then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of the Debentures, and shall
cause to be mailed to the Holders at their last addresses as they shall appear
upon the stock books of the Company, at least 20 calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided, that the
                                                         --------
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice. Holders are entitled to convert Debentures during the 20-day
period commencing the date of such notice to the effective date of the event
triggering such notice.

                    (x)    In case of any (1) merger or consolidation of the
Company with or into another Person, or (2) sale by the Company of more than
one-half of the assets of the Company in one or a series of related
transactions, a Holder shall have the right to (A) exercise any rights under
Section 3(b), (B) convert its aggregate principal amount of Debentures then
outstanding into the shares of stock and other securities, cash and property
receivable upon or deemed to be held by holders of Common Stock following such
merger, consolidation or sale, and such Holder shall be entitled upon such event
or series of related events to receive such amount of securities, cash and
property as the shares of Common Stock into which such

                                     -15-
<PAGE>

aggregate principal amount of Debentures could have been converted immediately
prior to such merger, consolidation or sales would have been entitled, or (C) in
the case of a merger or consolidation, require the surviving entity to issue to
the Holder convertible debentures with a principal amount equal to the aggregate
principal amount of Debentures then held by such Holder, plus all accrued and
unpaid interest and other amounts owing thereon, which newly issued convertible
debentures shall have terms identical (including with respect to conversion) to
the terms of this Debenture, and shall be entitled to all of the rights and
privileges of a Holder of Debentures set forth herein and the agreements
pursuant to which the Debentures were issued. In the case of clause (C), the
conversion price applicable for the newly issued shares of convertible preferred
stock or convertible debentures shall be based upon the amount of securities,
cash and property that each share of Common Stock would receive in such
transaction and the Conversion Price in effect immediately prior to the
effectiveness or closing date for such transaction. The terms of any such
merger, sale or consolidation shall include such terms so as to continue to give
the Holders the right to receive the securities, cash and property set forth in
this Section upon any conversion or redemption following such event. This
provision shall similarly apply to successive such events.

          (d)  The Company covenants that it will at all times reserve and keep
available out of its authorized and unissued shares of Common Stock solely for
the purpose of issuance upon conversion of the Debentures and payment of
interest on the Debentures, each as herein provided, free from preemptive rights
or any other actual contingent purchase rights of persons other than the
Holders, not less than such number of shares of the Common Stock as shall
(subject to any additional requirements of the Company as to reservation of such
shares set forth in the Purchase Agreement) be issuable (taking into account the
adjustments and restrictions of Section 4(b)) upon the conversion of the
outstanding principal amount of the Debentures and payment of interest
hereunder. The Company covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized, issued and fully
paid, nonassessable and, if the Underlying Shares Registration Statement has
been declared effective under the Securities Act, registered for public sale in
accordance with such Underlying Shares Registration Statement.

          (e)  Upon a conversion hereunder the Company shall not be required to
issue stock certificates representing fractions of shares of the Common Stock,
but may if otherwise permitted, make a cash payment in respect of any final
fraction of a share based on the Per Share Market Value at such time. If the
Company elects not, or is unable, to make such a cash payment, the Holder shall
be entitled to receive, in lieu of the final fraction of a share, one whole
share of Common Stock.

          (f)  The issuance of certificates for shares of the Common Stock on
conversion of the Debentures shall be made without charge to the Holders thereof
for any documentary stamp or similar taxes that may be payable in respect of the
issue or delivery of such certificate, provided that the Company shall not be
required to pay any tax that may be payable in respect of any transfer involved
in the issuance and delivery of any such certificate upon conversion in a name
other than that of the Holder of such Debentures so converted and the Company
shall not be required to issue or deliver such certificates unless or until the
person or

                                     -16-
<PAGE>

persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

          (g)    Any and all notices or other communications or deliveries to be
provided by the Holders hereunder, including, without limitation, any Conversion

right, exercisable at any time and from time to time after the Original Issue
Date, in accordance with the terms hereof and upon ten Trading Days' prior
written notice to the Holders to be prepaid (an "Optional Prepayment Notice"),
                                                 --------------------------
to prepay all or any portion of the outstanding principal amount of the
Debentures which has not previously been repaid or for which Conversion Notices
have not previously been delivered. The prepayment price applicable to
prepayments under this Section 5(a) shall equal the Prepayment Price and shall
be paid in cash. Any such prepayment shall be free of any claim of
subordination. The Holders shall have the right to tender, and the Company shall
honor, Conversion Notices delivered prior to the expiration of the tenth Trading
Day after receipt by the Holders of an Optional Prepayment Notice for such
Debentures (the tenth Trading Day after receipt by the Holders of an Optional
Prepayment Notice is referred to herein as the "Optional Prepayment Date")
                                                ------------------------

          (b)    The Company shall not be entitled to deliver an Optional
Prepayment Notice to the Holder (and, if after delivery thereof and prior to the
Optional Prepayment Date, any of the following conditions shall cease to be met,
such notice, at the option of the Holders,

                                     -17-
<PAGE>

shall be deemed no longer effective) if: (i) the number of shares of Common
Stock at the time authorized, unissued and unreserved for all purposes is
insufficient to satisfy the Company's conversion obligations of the aggregate
principal amount of Debentures then outstanding, or (ii) there is neither an
effective Underlying Shares Registration Statement under which the Holders can
resell all of the issued Underlying Shares and all of the Underlying Shares as
are issuable upon conversion in full of the principal amount of Debentures
subject to an Optional Prepayment Notice nor may all of such issued and issuable
Underlying Shares be sold by the Holders subject to such prepayment without
volume restrictions pursuant to Rule 144 promulgated under the Securities Act,
as determined by counsel to the Company pursuant to a written opinion letter,
addressed to the Company's transfer agent in the form and substance acceptable
to the Holders and such transfer agent, or (iii) the Common Stock is not then
listed or quoted for trading on the OTC or on a Subsequent Market.

          (c) If any portion of the Prepayment Price shall not be paid by the
Company by the second (2/nd/) Trading Day following the Optional Prepayment
Date, the Prepayment Price shall be increased by 15% per annum (or such lesser
maximum amount that is permitted to be paid by applicable law) to accrue daily
from the date such interest is due hereunder through and including the date of
payment (which amount shall be paid as liquidated damages and not as a penalty).
In addition, if any portion of the Prepayment Price remains unpaid through the
expiration of the Optional Prepayment Date, the Holder subject to such
prepayment may elect by written notice to the Company to either (x) demand
conversion in accordance with the formula and the time period therefor set forth
in Section 4 of any portion of the principal amount of Debentures for which the
Prepayment Price, plus accrued liquidated damages and accrued interest thereon,
has not been paid in full (the "Unpaid Prepayment Principal Amount"), in which
                                ----------------------------------
event the applicable Per Share Market Value shall be the lower of the Per Share
Market Value calculated on the Optional Prepayment Date and the Per Share Market
Value as of the Holder's written demand for conversion, or (y) invalidate ab
initio such optional prepayment, notwithstanding anything herein contained to
the contrary.  If the Holder elects option (x) above, the Company shall, within
five Trading Days after such election is deemed delivered hereunder, deliver to
the Holder the shares of Common Stock issuable upon conversion of the Unpaid
Prepayment Principal Amount subject to such conversion demand and otherwise
perform its obligations hereunder with respect thereto.  If the Holder elects
option (y) above, the Company shall promptly, and in any event not later than
five Trading Days from receipt of notice of such election, return to the Holder
new Debentures for the full Unpaid Prepayment Principal Amount and shall no
longer have any prepayment rights under this Debenture.  If, upon an election
under option (x) above, the Company fails to deliver certificates representing
the shares of Common Stock issuable upon conversion of the Unpaid Prepayment
Principal Amount within the time period set forth in this Section, the Company
shall pay to the Holder in cash, as liquidated damages and not as a penalty,
$2,500 per day until the Company delivers such certificates to the Holder.
