            UNSECURED SUBORDINATED PROMISSORY NOTE DUE June 14, 2011

     THIS UNSECURED SUBORDINATED PROMISSORY NOTE of Environmental Solutions

Company and the Holder (as defined below) (the "Note Subscription Agreement")
(including all Unsecured Subordinated Promissory Notes issued in exchange,
transfer or replacement hereof, this "Note"), designated as one of its Unsecured
Subordinated Promissory Notes Due June 14, 2011, in an aggregate principal
amount of U.S.$[____] (collectively, the "Notes").

     FOR VALUE RECEIVED, the Company promises to pay to [_________________] (or
his or its permitted assigns) the registered holder hereof (the "Holder"), the
principal sum of $[_______], on or prior to June 14, 2011 (the "Maturity Date"),
subject to Section 1, and to pay interest in-kind (through the issuance of
substantially similar Notes) on the principal sum outstanding on a monthly basis
(each such date of payment an "Interest Payment Date"), commencing May 27, 2011,
up to and including the date on which this Note has been paid in full, at the
rate of 10% per annum, and shall be computed on the basis of a 365-day year and
actual days elapsed (depending upon the subscription date). Accrual of interest

Note is payable in currency of the United States of America or pursuant to the
terms of Section 1 below, or such other manner of payment, at the sole option of
the Holder. The Notes Register shall represent the record of ownership and right

shall be payable only to the registered Holder as reflected in the Notes
Register. The right to receive principal and interest payments under this Note
shall be transferable only through an appropriate entry in the Notes Register as

     This Note is subject to the following additional provisions:

     1. No Prepayment; Exchange Rights and Obligations. (a) The Company shall
not prepay any amount of principal or accrued interest outstanding under this
Note prior to the Maturity Date without the prior written consent of the Holder;
provided, that in the event the Borrower has failed to close an offering of
shares of its common stock, par value $0.001 per share (the "Common Stock") that
are registered under the Act, at a sale price of $0.12 per share (as adjusted
for any stock split, stock dividend or other similar adjustment) pursuant to a
rights offering of the Company that raises at least an incremental $2.5 million
of cash for the Company and also permits all holders of the Notes to exchange
their Notes (and the other notes paid in kind for the payment of interest under
the Notes) for shares of Common Stock at such price (with such closed offering
referred to herein as the "Qualified Offering") on or prior to the Maturity
Date, then the Holder, at his or its sole option, may require the Company to
refrain from making any and all payments on any of the outstanding principal and
accrued interest outstanding under this Note; provided, however, the Company is
not prohibited hereunder from paying any accrued interest in-kind through the
issuance of substantially similar Notes, at any time.

     (b) If, prior to the payment of all principal or accrued interest
outstanding under this Note, the Company closes a Qualified Offering on or prior
to the Maturity Date, then the Holder may elect to (i) exchange any outstanding
Notes then held by him or it for a subscription of the Common Stock in the
Qualified Offering as payment by the Holder of the subscription price therefor
(but excluding from exchange any portion of the Notes that are not permitted by
the terms of the Qualified Offering to be exchanged in the Qualified Offering
(i.e., if the amount owing under the Notes exceeds the permitted pro-rata
participation level made available to the Holder in the Qualified Offering)),
(ii) purchase for cash an equivalent number of shares of Common Stock as would
be issued pursuant to the exchange provided for in clause (i) of this Section
1(b) or (iii) be repaid from the proceeds of such Qualified Offering, all
amounts outstanding under the Notes then held by him or it; provided, that any
such repayment shall be subject to the terms of the Postponement And
Subordination Agreement dated as of the 16th day of February, 2011 by and among
the Holder, Canadian Imperial Bank of Commerce and the other parties thereto (as
amended, modified or supplemented from time to time, the "Subordination
Agreement").

     (c) In the event (i) the Qualified Offering closes on or prior to the
Maturity Date and (ii) for any reason the Holder shall have failed to have
exchanged in the Qualified Offering any and all principal or accrued interest
outstanding under this Note and (iii) the Holder wishes to exchange for Common
Stock at a price of $0.12 per share (as adjusted for any stock split, stock
dividend or other similar adjustment), then the Company [at its sole option]
shall be required to (i) offer the Holder the immediate right to purchase
additional shares of Common Stock at such price, so that all principal and
accrued interest outstanding under this Note shall have been exchanged for
shares of Common Stock at such price or (ii) subject to the terms of the
Subordination Agreement, repay all principal and accrued interest outstanding
under this Note from the proceeds of such Qualified Offering.

     (d) At any time after the Maturity Date, if any amount of principal or
accrued interest remains outstanding under this Note, the Holder shall have the
right and option (but not the obligation) to exchange any or all
then-outstanding amount of principal or accrued interest under this Note in any
offering or other sale made by the Company for any shares of Common Stock (or
any other equity securities or equity-linked rights or securities whatsoever)
(as payment by the participating Holder of the sale price therefor).

     (e) The Holder may, at his or its sole option, extend the Maturity Date.

Notes of different authorized denominations, as requested by the Holders

("CIBC") and shall be subject to the terms of the Subordination Agreement.

17. Payment of Collection, Enforcement and Other Costs. If (a) this Note is
placed in the hands of an attorney for collection or enforcement or is collected
or enforced through any legal proceeding or the Holder otherwise takes action to
collect amounts due under this Note or to enforce the provisions of this Note or
(b) there occurs any bankruptcy, reorganization, receivership of the Company or
other proceedings affecting Company creditors' rights and involving a claim

18. Construction; Headings. This Note shall be deemed to be jointly drafted by
the Company and the Holder and shall not be construed against any person as the
drafter hereof. The headings of this Note are for convenience of reference and
shall not form part of, or affect the interpretation of, this Note.

19. Remedies, Characterizations, Other Obligations, Breaches and Injunctive
Relief. The remedies provided in this Note shall be cumulative and in addition

Documents (as defined in the Note Subscription Agreement), at law or in equity
(including a decree of specific performance and/or other injunctive relief), and
nothing herein shall limit the Holder's right to pursue actual damages for any
failure by the Company to comply with the terms of this Note. Amounts set forth
or provided for herein with respect to payments shall be the amounts to be
received by the Holder and shall not, except as expressly provided herein, be
subject to any other obligation of the Company (or the performance thereof). The
Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Holder and that the remedy at law for any such breach
may be inadequate. The Company therefore agrees that, in the event of any such
breach or threatened breach, the Holder shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being
required.

20. Waiver of Notice. To the extent permitted by law, the Company hereby waives
demand, notice, protest and all other demands and notices in connection with the
delivery, acceptance, performance, default or enforcement of this Note and the
Note Subscription Agreement.
