                       ACCORD ADVANCED TECHNOLOGIES, INC.
                            12% CONVERTIBLE DEBENTURE
                                DUE MAY 31, 2002

     THIS DEBENTURE is one of a series of duly authorized and issued debentures
of ACCORD ADVANCED TECHNOLOGIES, INC., a Nevada corporation, having a principal
place of business c/o Robson, Ferber, Frost, Chan & Esser LLP, 530 Fifth Avenue,
23rd Floor, New York, New York 10036, as the successor entity of the Agreement
and Plan of Reorganization between Accord Advanced Technologies, Inc. and
ENPETRO Mineral Pool dated April 30, 2001 (the "COMPANY"), designated as its 12%
Convertible Debentures, due May 31, 2002, in the aggregate principal amount of
One Hundred Fifty Thousand and no/100 ($150,000.00) (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
One Hundred Fifty Thousand and no/100 ($150,000) on May 31, 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 such Debentures are 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 June 30, 2001, in cash or shares
of Common Stock (as defined in Section 6). Subject to the terms and conditions
herein, the decision whether to pay interest hereunder in shares of Common Stock
or cash shall be at the discretion of the Company. Not less than ten Trading
Days (as defined in Section 6) prior to each Conversion Date, the Company shall
provide the Holder with written notice of its election to pay interest hereunder
either in cash or shares of Common Stock pursuant to the terms of Section
4(a)(i) (the Company may indicate in such notice that the election contained in
such notice shall continue for later periods until revised). Failure to timely
provide such written notice shall be deemed an election by the Company to pay
<PAGE>
the interest on such Conversion Date in shares of Common Stock pursuant to the
terms of Section 4(a)(i). If interest is paid in shares of Common Stock, 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 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 "DEBENTURE REGISTER"). All overdue accrued and unpaid interest
to be paid in 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) (to accrue daily, from the date such interest is due hereunder
through and including the date of payment), payable in cash.

     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
Holder surrendering the same. No service charge will be made for such
registration of transfer or exchange.

     SECTION 2. This Debenture has been issued subject to certain investment
representations of the original Holder set forth in the Purchase Agreement (as
defined in Section 6) and may be transferred or exchanged only in compliance
with the Purchase Agreement. Prior to due presentment to the Company for
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
receiving payment as herein provided and for all other purposes, whether or not
this Debenture is overdue, and neither the Company nor any such agent shall be
affected by notice to the contrary.

     SECTION 3. EVENTS OF DEFAULT.

         (a) "EVENT OF DEFAULT", wherever used herein, means any one of the
following events (whatever the reason and whether it shall be voluntary or

for borrowed money or money due under any long term leasing or factoring
arrangement of the Company in an amount exceeding two hundred fifty thousand

eligible for and quoted or listed for trading thereon within five Trading Days;

               (vi) the Company shall be a party to any Change of Control

                                       3
<PAGE>
number of shares of Common Stock or other equity securities of the Company
(other than redemptions of Underlying Shares (as defined in Section 6));

               (vii) an Underlying Shares Registration Statement (as defined in
Section 6) shall not have been declared effective by the Commission (as defined
in Section 6) on or prior to the 120th day after the Original Issue Date;

               (viii) if, during the Effectiveness Period (as defined in the

the Underlying Shares Registration Statement lapses for any reason or the Holder
shall not be permitted to resell Registrable Securities (as defined in the
Registration Rights Agreement) under the Underlying Shares Registration
Statement, in either case, for more than five consecutive Trading Days or an
aggregate of eight Trading Days (which need not be consecutive Trading Days);

               (ix) an Event (as defined in the Registration Rights Agreement)

shall be covered by Section 3(a)(vii));

               (x) the Company shall fail for any reason to deliver certificates
to a Holder prior to the third Trading Day after a Conversion Date pursuant to
and in accordance with Section 4(b) or the Company shall provide notice to the
Holder, including by way of public announcement, at any time, of its intention
not to comply with requests for conversions of any Debentures in accordance with
the terms hereof;

               (xi) the Company shall fail for any reason to deliver the payment
in cash pursuant to a Buy-In (as defined herein) within five days after notice
is deemed delivered hereunder; or

               (xii) there shall have occurred a breach of the Security
Agreement which shall not have been remedied prior to the tenth day following
notice thereof.

         (b) During the time that any portion of this Debenture remains
outstanding, if any Event of Default occurs and is continuing, the full
principal amount of this Debenture (and, at the Holder's option, all other
Debentures then held by such Holder), together with interest and other amounts
owing in respect thereof, to the date of acceleration shall become, immediately
due and payable in cash. The aggregate amount payable upon an Event of Default
shall be equal to the sum of (i) the Mandatory Prepayment Amount (as defined in
Section 6) plus (ii) the product of (A) the number of Underlying Shares issued
in respect of conversions hereunder within thirty (30) days of the date of a
declaration of an Event of Default and then held by the Holder and (B) the Per
Share Market Value (as defined in Section 6) on the date prepayment is due or
the date the full prepayment price is paid, whichever is greater. Interest shall

                                       4
<PAGE>
accrue on the prepayment amount hereunder from the seventh day after such amount
is due (being the date of an Event of Default) through the date of prepayment in
full thereof at the rate of 15% per annum (or such lesser maximum amount that is
permitted to be paid by applicable law), to accrue daily from the date such
payment is due hereunder through and including the date of payment. All
Debentures and Underlying Shares for which the full prepayment price hereunder
shall have been paid in accordance herewith shall promptly be surrendered to or
as directed by the Company. The Holder need not provide and the Company hereby
waives any presentment, demand, protest or other notice of any kind, and the
Holder may immediately and without expiration of any grace period enforce any
and all of its rights and remedies hereunder and all other remedies available to
it under applicable law. Such declaration may be rescinded and annulled by
Holder at any time prior to payment hereunder. 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)(iii)
hereof). The number of shares of Common Stock issuable upon a conversion
hereunder shall be determined by adding the sum of (i) the quotient obtained by
dividing (x) the outstanding principal amount of this Debenture to be converted
and (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 Company shall have timely elected to pay the interest due on a Conversion
Date in cash pursuant to the terms hereof, subsection (ii) shall not be used in
the calculation of the number of shares of Common Stock issuable upon a
conversion hereunder.

         (B) Notwithstanding anything to the contrary contained herein, if on
any Conversion Date:

               (1) the number of shares of Common Stock at the time authorized,
unissued and unreserved for all purposes, or held as treasury stock, is
insufficient to pay interest hereunder in shares of Common Stock;

               (2) after the Interest Effectiveness Date (as defined in Section
6) such shares of Common Stock (x) are not registered for resale pursuant to an
effective Underlying Shares Registration Statement and (y) may not be sold
without volume restrictions pursuant to Rule 144(k) promulgated under the
Securities Act (as defined in Section 6), 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 applicable Holder and
such transfer agent (if the shares of Common Stock are permitted by the Holder
to be delivered under this clause (2) prior to the Effectiveness Date (as
defined in the Registration Rights Agreement) and thereafter an

                                       5
<PAGE>
Underlying Shares Registration Statement shall be declared effective by the
Commission, the Company shall, within five Trading Days after the date of such
declaration of effectiveness, exchange such shares for shares of Common Stock
that are free of restrictive legends of any kind);

               (3) the Common Stock is not listed or quoted for trading on the
OTC or on a Subsequent Market;

               (4) the Company has failed to timely satisfy its conversion
obligations hereunder; or

               (5) the issuance of such shares of Common Stock would result in a
violation of Sections 4(a)(iii),

         then, at the option of the Holder, the Company, in lieu of delivering
shares of Common Stock pursuant to Section 4(a)(i)(A)(ii), shall deliver, within
three Trading Days of each applicable Conversion Date, an amount in cash equal
to the product of (a) the outstanding principal amount of the Debentures to be
converted on such Conversion Date and (b) the product of (x) the quotient
obtained by dividing .12 by 360 and (y) the number of days for which such
principal amount was outstanding.

         (C) The Holder shall effect conversions by surrendering the Debentures
(or such portions thereof) to be converted, together with the form of conversion
notice attached hereto as EXHIBIT A (a "CONVERSION NOTICE") to the Company. Each
Conversion Notice shall specify the principal amount of Debentures to be
converted and the date on which such conversion is to be effected, which date
may not be prior to the date such Conversion Notice is deemed to have been
delivered hereunder (a "CONVERSION DATE"). If no Conversion Date is specified in
a Conversion Notice, the Conversion Date shall be the date that such Conversion
Notice is deemed delivered hereunder. Subject to Section 4(b), each Conversion
Notice, once given, shall be irrevocable. If the Holder is converting less than
all of the principal amount represented by the Debenture(s) tendered by the
Holder with the Conversion Notice, or if a conversion hereunder cannot be
effected in full for any reason, the Company shall honor such conversion to the
extent permissible hereunder and shall promptly deliver to such Holder (in the
manner and within the time set forth in Section 4(b)) a new Debenture for such
principal amount as has not been converted.

         (ii) AUTOMATIC CONVERSION. Subject to the provisions in this paragraph,
the principal amount of Debentures for which conversion notices have not
previously been received or for which prepayment has not been made or required
hereunder shall be automatically converted on the first anniversary of the
Original Issue Date (the "AUTOMATIC CONVERSION DATE") pursuant to Section
4(a)(i), at the Conversion Price on such date. The conversion contemplated by
this paragraph shall not occur if (a) (1) an Underlying Securities Registration
Statement is not then effective that names the Holder as a selling stockholder
thereunder and (2) the Holder is not permitted to resell Underlying Shares
pursuant to Rule 144(k) promulgated under the Securities Act, without volume
restrictions, as evidenced by an opinion letter of counsel acceptable to the
Holder and the transfer agent for the Common Stock; or (b) there are not

                                       6
<PAGE>
sufficient shares of Common Stock authorized and reserved for issuance upon such
conversion. Notwithstanding anything herein to the contrary, the Automatic
Conversion Date shall be extended (on a day-for-day basis) for any Trading Days
that the Holder is unable to resell Underlying Shares due to (a) the Common
Stock not being listed or granted for trading on the OTC or any Subsequent
Market, (b) the failure of an Underlying Securities Registration Statement to be
declared effective by the Commission or, if so declared, to remain effective
during the Effectiveness Period as to all Underlying Shares, or (c) the
suspension of the Holder's right to resell Underlying Shares thereunder.
Notwithstanding anything to the contrary contained herein, a conversion pursuant
to this Section shall not be subject to the provisions of Section 4(a)(iii).

         (iii) CERTAIN CONVERSION RESTRICTIONS.

               (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

                                       7
<PAGE>
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 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 five 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 being acquired upon the conversion of Debentures (subject
to the limitations set forth in Section 4(a)(iii) hereof), (ii) Debentures in a
principal amount equal to the principal amount of Debentures not converted, and
(iii) a bank check in the amount of accrued and unpaid interest (if the Company
has timely elected or is required to pay accrued interest in cash), PROVIDED,
that the Company shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon conversion of the principal amount of
Debentures until Debentures are delivered for conversion to the Company, or the
Holder notifies the Company that such Debentures have been lost, stolen or
destroyed and provides a bond (or other adequate security) reasonably
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection therewith. The Company shall, upon request of the Holder, if
available, use its best efforts to deliver any certificate or certificates
required to be delivered by the Company under this Section electronically
through the Depository Trust Corporation or another established clearing
corporation performing similar functions. If in the case of any Conversion
Notice such certificate or certificates are not delivered to or as directed by
the applicable Holder by the fifth 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 certificate or certificates thereafter, to rescind
such conversion, in which event the Company shall immediately return the
certificates representing the principal amount of Debentures tendered for
conversion.

               (ii) If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 4(b)(i) by the fifth 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

                                       8
<PAGE>
fifth 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 to deliver to the Holder such certificate or certificates
pursuant to Section 4(b)(i) by the fifth Trading Day after the Conversion Date,
and if after such fifth 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) $.23 (the "INITIAL CONVERSION
PRICE"), and (2) 60% of the average of the lowest three inter-day prices (which
need not occur on consecutive Trading Days) 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

                                       9
<PAGE>
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 any 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) DELETED,
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 (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 any 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.

                                       10
<PAGE>
               (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 either (i) shares of Common Stock at a
price per share less than the Conversion Price (the "ISSUANCE PRICE") or (ii)
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 an Issuance Price less
than the Conversion Price (if the holder of the 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
be entitled to receive shares of Common Stock at a conversion or exercise price
less than the Conversion Price, such issuance shall be deemed to have occurred
for less than the Conversion Price), then, the Conversion Price shall be reduced
to the Issuance Price. Such adjustment shall be made whenever Common Stock or
Common Stock Equivalents are issued at a price below the Conversion Price.
However, upon the expiration of any Common Stock Equivalents the issuance of
which resulted in an adjustment in the Conversion Price pursuant to this
Section, if any such Common Stock Equivalents 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 Common Stock Equivalents) had the adjustment of the Conversion
Price made upon the issuance of such Common Stock Equivalents been made on the
basis of offering for subscription or purchase only that number of shares of
Common Stock actually purchased upon the exercise of such Common Stock
Equivalents actually exercised.

               (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

                                       11
<PAGE>
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 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.

                                       12
<PAGE>
               (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 (on an as valued basis) in one or a series of related
transactions, a Holder shall have the right to (A) if permitted under Section
3(b) hereof, exercise its rights of prepayment under Section 3(b) with respect
to such event, (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 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, (x) require the surviving entity to issue shares of
convertible preferred stock or convertible debentures with such aggregate stated
value or in such face amount, as the case may be, 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 shares of
preferred stock or debentures shall have terms identical (including with respect
to conversion) to the terms of this Debenture (except, in the case of preferred
stock, as may be required to reflect the differences between equity and debt)
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 (including, without limitation, as such rights relate to the
acquisition, transferability, registration and listing of such shares of stock
other securities issuable upon conversion thereof), and (y) simultaneously with
the issuance of such convertible preferred stock or convertible debentures,
shall have the right to convert such instrument only into shares of stock and
other securities, cash and property receivable upon or deemed to be held by
holders of Common Stock following such merger or consolidation. 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

                                       13
<PAGE>
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 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
Notice, shall be in writing and delivered personally, by facsimile, sent by a
nationally recognized overnight courier service or sent by certified or
registered mail, postage prepaid, addressed to the Company, c/o Robson, Ferber,

     SECTION 5. OPTIONAL PREPAYMENT.

         (a) Subject to Section 5(b) below, the Company shall have the right,
exercisable within 40 days of the date hereof, 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, 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 fifth (5th) 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

                                       15
<PAGE>
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.
