    FOR VALUE RECEIVED, Power Efficiency Corporation, a Delaware corporation
(the "Borrower") hereby promises to pay to Summit Energy Ventures, LLC, a
Delaware limited liability company (the "Lender"), by wire transfer of
immediately available United States federal funds to the Lender's designated
account or, if the Lender so agrees, by the Borrower's check, the aggregate
principal sum of $1,000,000, or such lesser aggregate amount as is advanced
and outstanding (each such advance, a "Loan") pursuant to the provisions of
this Revolving Credit Note (this "Note"), together with interest in like money

shall be payable (a) upon the payment or prepayment of each Loan (but only on
the principal amount so paid or prepaid) and (b) on the Maturity Date (as
defined below). All principal then outstanding, and all interest, fees,
charges, and other amounts owing under this Note and then unpaid shall be due
and payable on December 31, 2003 (the "Maturity Date"). All payments on or in
respect of this Note shall be made to the Lender without set-off or
counterclaim and free and clear of and without deductions of any kind.

    This Note is secured by, and entitled to the benefits of, the Security
Agreement dated of even date with this Note between the Borrower and the
Lender (the "Security Agreement").

    In this Note, the following terms shall have the following respective
meanings:

<PAGE>

    1.  Borrowings. The Lender agrees, subject to the terms and conditions of
this Note, to make Loans to the Borrower, from time to time during the period
from the date of this Note up to and including December 19, 2003 (the
"Commitment Termination Date"), in an aggregate principal amount not to exceed
at any time $1,000,000 (the "Total Commitment"). Unpaid interest and fees
shall be considered when calculating the Total Commitment. The initial Loan
under this Note shall be in the amount of $250,000. Each subsequent Loan under
this Note shall be in an amount that is an integral multiple of $50,000 and is
not, in the aggregate, less than $100,000 or more than $200,000. The Borrower
shall give the Lender written request for each Loan: (a) in the case of the
first Loan under this Note, at least two (2) Business Days, and (b) in the
case of all subsequent Loans, at least seven (7) Business Days, prior to the
date on which the Borrower wishes the Lender to fund such Loan; provided that
in no event shall the Borrower be permitted to request more than one Loan in
any given calendar month. Upon receipt of such written request for a Loan, the
Lender shall make each requested Loan available to the Borrower, in
immediately available funds by wire transfer to the account designated by the
Borrower on its request for a Loan, on the Business Day designated by the
Borrower in its notice.

    The Borrower hereby authorizes the Lender to endorse on the Schedule
annexed to this Note the principal amount of each Loan made to the Borrower
and all payments of principal and interest in respect of each such Loan, which
endorsements shall, in the absence of manifest error, be conclusive; provided,
however, that the failure to make such notation with respect to any Loan or
payment shall not limit or otherwise affect the obligations of the Borrower
hereunder.

    2.  Optional Prepayment; Premium. The Borrower may prepay the principal and
interest due on any Loan, at any time, in whole or in part, without penalty or
premium. Subject to the terms and conditions of this Note, during the period
from the date of this Note up to and including the Commitment Termination Date,
the Borrower may borrow, repay and reborrow the amount of the Total Commitment
by means of Loans; provided that in no event shall the Borrower be permitted to
request more than one Loan in any given calendar month.

    3.  Conversion. The Lender may at any time prior to Maturity Date give the
Borrower written notice (the "Conversion Notice") of its desire to convert, in
full or in part, the outstanding balance of all principal and interest on the
Loans and all other amounts owing to the Lender under this Note and the other
Basic Documents (such amount being the "Conversion Amount") into fully paid
and nonassessable shares of the Series A-1 Preferred Stock, par value $0.001
per share, of the Borrower (the "Stock"), on the basis of one share of Stock
for each $1.065538 (the "Conversion Price") of the Conversion Amount.

    The Conversion Notice shall set forth (a) the Conversion Price, (b) the
number of shares of Stock representing the Conversion Amount, (c) the date on
which the Conversion shall take place, which date shall not, in any event, be
less than seven days after the date of the Conversion Notice (the "Conversion
Date") and (d) instructions for delivery of the applicable number of shares of
Stock to the Lender.

    Upon receipt of the Conversion Notice from the Lender, the Borrower shall
have seven days to repay in full the Conversion Amount. If the Borrower does
not pay the Conversion Amount within that seven-day period, then on the
Conversion Date:

                                       2
<PAGE>

    (i) the Conversion Amount shall convert into Stock;

    (ii) the Total Commitment shall automatically be reduced by the amount of
principal on the Loans reflected in the Conversion Amount (which principal
amount shall be set forth in the Conversion Notice);

    (iii) the Conversion Amount so converted into Stock shall be deemed to
constitute a partial prepayment of the amounts of principal and interest on
the Loans and other amounts owing by the Borrower to the Lender under this
Note and the other Basic Documents, thereby reducing the obligations of the
Borrower to the Lender by the Conversion Amount; and

    (iv) the Lender shall become the holder of record of the shares of Stock
represented by the Stock certificates to be delivered by the Borrower pursuant
to this Section 3.

    As soon as practicable after the Conversion Date (and in any event no
later than 10 Business Days after the Conversion Date), the Borrower shall
deliver to the Lender the Stock certificates representing the number of shares
of Stock issuable pursuant to the Conversion Notice.

    Notwithstanding any other provisions of this Section 3 to the contrary, in
the event of a conversion under this Section 3, this Note, the Security
Agreement and all other Basic Documents shall remain in full force and effect.

    4.  Lending Fee. Concurrently with the first Loan made under this Note, the
Borrower shall be obligated to pay to the Lender a lending fee in the amount
of $50,000 (the "Lending Fee"). The Lending Fee shall be deducted by the
Lender from the amount of the initial Loan made under this Note.

    5.  Notices. Unless otherwise indicated differently, all notices, requests,
reports, information or demands which either party may desire or may be
required to give to the other party shall be in writing and shall be
personally delivered, sent by facsimile, by a reliable overnight mail delivery
service providing a receipt or by first-class certified or registered United
States mail, postage prepaid return receipt requested, and sent to the
receiving party at its address appearing below or at such other address as
that party shall designate to the other party by written notice; (provided,
however, notices to the Lender requesting disbursements need not be sent by

Document constitutes a legal, valid and binding obligation of the Borrower,
enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors'
rights generally and subject to general principles of equity, regardless of
whether considered in a proceeding in equity or at law.

    (c)  Governmental Approvals; No Conflicts. The transactions contemplated

not result in the creation or imposition of any lien on any property or asset of
the Borrower other than the liens created under the Security Agreement.

    (d)  Properties and Assets.

         (i) The Borrower has good title to all its property and assets, free

their intended purposes.

         (ii) The Borrower owns, or is licensed to use, all trademarks, trade
names, copyrights, patents and other intellectual property material to its
business, and the use of any such property by the Borrower does not infringe
upon the rights of any other person or entity.

there are no actions, suits or proceedings by or before any arbitrator or
governmental authority pending against or, to the knowledge of the Borrower,
threatened against or affecting the Borrower (i) as to which there is a

determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Condition.

                             Disclosure re Disputes

1.      Stephen Shulman: The Borrower is involved with certain claims and
        counterclaims related to arbitration with its former CEO, Stephen
        Shulman. The claim was filed by the former CEO on October 10, 2002 and
        is being administrated by the East Providence, Rhode Island office of
        the American Arbitration Association. The former CEO is claiming the
        Borrower owes him, and is seeking to recover, approximately $528,659.
        The amount of his claim is comprised of (i) $116,039 for unpaid salary
        and expenses, and (ii) $412,620 for a payment owed to him in the case
        of a change of control of the Borrower. The Borrower is currently
        defending these claims.

2.      Warner Norcross & Judd LLP: The Borrower received certain services from
        a law firm, Warner Norcross & Judd LLP ("WNJ"). The Borrower received
        an invoice from WNJ that it believes was unreasonably high. The invoice
        was for approximately $200,000 which the Borrower believes is
        approximately two times the reasonable value of the services provided.
        The Borrower has paid approximately $80,000 of the outstanding balance
        and is in negotiations with WNJ regarding the unpaid portion of the
        invoice.

        in its discretion accept).

        action as the Lender reasonably may deem desirable to create, perfect
        and establish the priority of the liens granted by this Agreement in
        any and all of the Collateral, to preserve the validity, perfection or
        priority of the liens granted by this Agreement in any and all of the
        Collateral, and otherwise to enable the Lender to obtain the full
        benefits of this Agreement and of the rights and powers herein granted,
        including the filing of any financing or continuation statements under
        the Code in effect in any jurisdiction with respect to the liens and
        security interests granted hereby. The Borrower also hereby authorizes
        the Lender to file any such financing or continuation statement without
        the signature of the Borrower to the extent permitted by applicable
        law. If any amount payable under or in connection with any of the
        Collateral shall be or become evidenced by any promissory note or other
        instrument, such note or instrument shall immediately become a part of
        the Collateral and shall be pledged to the Lender, duly endorsed by the
        Borrower in a manner satisfactory to the Lender.

                                       5

             (b) Maintenance of Records. The Borrower will keep and maintain at
        its own cost and expense satisfactory and complete records of the
        Collateral including a record of all payments received and all credits
        granted with respect to the Collateral and all other dealings with the
        Collateral. The Borrower will mark, to the extent feasible, its books
        and records pertaining to the Collateral to evidence this Agreement and
        the security interests granted hereby. For the Lender's further
        security, the Borrower agrees that the Lender shall have a special
        property interest in all of the Borrower's books and records pertaining
        to the Collateral and the Borrower shall deliver and turn over copies
        of any such books and records to the Lender or to its representatives
        at any time on reasonable demand of the Lender.

             (c) Indemnification. In any suit, proceeding or action brought by
        the Lender under any contract or agreement that is a part of the
        Collateral for any sum owing thereunder, or to enforce any provisions
        of such contract or agreement, the Borrower will save, indemnify and
        keep the Lender harmless from and against all expense, loss or damage
        suffered by reason of any defense, setoff, counterclaim, recoupment or
        reduction of liability whatsoever of the person or entity against whom
        such suit, proceedings or action is brought, arising out of a breach by
        the Borrower of any obligation thereunder or arising out of any other
        agreement, indebtedness or liability at any time owing to or in favor
        of such obligee or its successors from the Borrower, and all such
        obligations of the Borrower shall be and remain enforceable against and
        only against the Borrower and shall not be enforceable against the
        Lender.

             (d) Compliance with Laws, etc. The Borrower will comply, in all
        material respects, with all acts, rules, regulations, orders, decrees
        and directions of any governmental authority, applicable to the
        Collateral or any part thereof; provided, however, that the Borrower
        may contest any act, regulation, order, decree or direction in any
        reasonable manner.

             (e) Payment of Obligations. The Borrower will pay promptly when
        due, all taxes, assessments and governmental charges or levies imposed
        upon the Collateral or in respect of its income or profits therefrom,
        as well as all claims of any kind (including claims for labor,
        materials and supplies), except that no such charge need be paid if (i)
        the validity thereof is being contested in good faith by appropriate
        proceedings, (ii) such proceedings do not involve any danger of the
        sale, forfeiture or loss of any of the Collateral or any interest
        therein and (iii) such charge is adequately reserved against in
        accordance with generally accepted accounting principles.

                                       6
<PAGE>

             (f) Limitation on Sale and Liens. Other than as set forth in the
        Note, the Borrower will not (i) dispose of the Collateral, (ii) permit
        any person other than the Lender to have control of any deposit
        account, electronic chattel paper, investment property or letter-of-
        credit right included in the Collateral and (iii) create, permit or
        suffer to exist, and will defend the Collateral against and take such
        other action as is necessary to remove, any lien, security interest,
        encumbrance, claim or right, in or to the Collateral, and will defend
        the right, title and interest of the Lender in and to any of the
        Borrower's rights under and in the Collateral against the claims and
        demands of all persons whomsoever.

             (g) Removals; Further Identification of Collateral. Without at
        least 30 days' prior written notice to the Lender, the Borrower shall
        not (i) change its location (as that term is defined in the Code) from
        that shown on Schedule 4(a), (ii) change its name from the name shown
        on Schedule 4(a) as its current legal name or (iii) permit any Goods to
        be located anywhere other than at one of the locations identified in
        Schedule 4(d) or in transit from one of those locations to another. The
        Borrower will furnish promptly to the Lender upon request statements
        and schedules further identifying, describing and stating the physical
        location of the Collateral and such other reports in connection with
        the Collateral as the Lender reasonably may request at any time, all in
        reasonable detail.

             (h) Notices. The Borrower will advise the Lender promptly, in
        reasonable detail, (i) of any lien, security interest, encumbrance or
        claim made or asserted against any of the Collateral, (ii) of any
        material change in the composition of the Collateral not in the
        ordinary course of business, and (iii) of the occurrence of any other
        event which would have a material adverse effect on the aggregate value
        of the Collateral or on the security interests created hereunder not in
        the ordinary course of business.

             (i) Right of Inspection. The Lender shall at all times have full
        and free access during normal business hours to all the books,
        correspondence and records of the Borrower, and the Lender or its
        representatives may examine the same, take extracts therefrom and make
        photocopies thereof, and the Borrower agrees to render to the Lender,
        at the Borrower's cost and expense, such clerical and other assistance
        as may be reasonably requested with regard thereto. The Lender and its
        representatives shall at all times also have the right to enter into
        and upon any premises where any of the Collateral is located for the
        purpose of inspecting the same, observing its use or otherwise
        protecting the interests of the Lender therein.

    6. The Lender's Appointment as Attorney-in-Fact.

             (a) The Borrower hereby irrevocably constitutes and appoints the
       Lender and any officer or agent thereof, with full power of substitution,
       as its true and lawful attorney-in-fact with full irrevocable power and
       authority in the place and stead of the Borrower and in the name of the
       Borrower or in its own name, from time to time in the Lender's
       discretion, for the purpose of carrying out the terms of this Agreement,
       to take any and all appropriate action and to execute any and all
       documents and instruments which may be necessary or desirable to
       accomplish the purposes of this Agreement and, without limiting the
       generality of the foregoing, hereby gives the Lender the power and right,
       on behalf of the Borrower, without notice to or assent by the Borrower,
       to do the following:

               (i)  to create, perfect and establish the priority of the liens
               granted by this Agreement in any and all the Collateral, to
               preserve the validity, perfection or priority of the liens
               granted by this Agreement in any and all of the Collateral or
               to enable the Lender to exercise its remedies, rights, powers
               and privileges under this Agreement;

               (ii)  upon the occurrence and continuance of any Default or
               Event of Default, to ask, demand, collect, receive and give
               acquittances and receipts for any and all moneys due and to
               become due under any contract or account that is a part of the
               Collateral and, in the name of the Borrower or its own name or
               otherwise, to take possession of and endorse and collect any
               checks, drafts, notes, acceptances or other instruments for the
               payment of moneys due under any contract or account that is a
               part of the Collateral and to file any claim or to take any
               other action or proceeding in any court of law or equity or
               otherwise deemed appropriate by the Lender for the purpose of
               collecting any and all such moneys due under any such contract
               or account whenever payable;

               (iii)  to pay or discharge taxes, liens, security interests or
               other encumbrances levied or placed on or threatened against
               the Collateral; and

               (iv)  upon the occurrence and continuance of any Default or
               Event of Default, (A) to direct any party liable for any
               payment under any of the contracts or accounts that are a part
               of the Collateral to make payment of any and all moneys due and
               to become due thereunder directly to the Lender or as the
               Lender shall direct; (B) to receive payment of and receipt for
               any and all moneys, claims and other amounts due and to become
               due at any time in respect of or arising out of any Collateral;
               (C) to commence and prosecute any suits, actions or proceedings
               at law or in equity in any court of competent jurisdiction to
               collect the Collateral or any part thereof and to enforce any
               other right in respect of any Collateral; (D) to defend any
               suit, action or proceeding brought against the Borrower with
               respect to any Collateral; (E) to settle, compromise or adjust
               any suit, action or proceeding described above and, in
               connection therewith, to give such discharges or releases as
               the Lender may deem appropriate; and (F) generally to sell,
               transfer, pledge, make any agreement with respect to or
               otherwise deal with any of the Collateral as fully and
               completely as though the Lender were the absolute owner thereof
               for all purposes, and to do, at the Lender's option and the
               Borrower's expense, at any time, or from time to time, all acts
               and things which the Lender deems necessary to protect,
               preserve or realize upon the Collateral and the Lender's
               security interest therein, in order to effect the intent of
               this Agreement, including the preparation, execution and
               recordation of patent, trademark or other forms of assignment,
               all as fully and effectively as the Borrower might do.

                                       8

               The Borrower hereby ratifies all that said attorneys-in-fact
        shall lawfully do or cause to be done by virtue hereof. This power of
        attorney is a power coupled with an interest and is irrevocable.

             (b) The powers conferred on the Lender hereunder are solely to
        protect its interests in the Collateral and shall not impose any duty
        upon it to exercise any such powers. The Lender shall be accountable
        only for amounts that it actually receives as a result of the exercise
        of such powers and neither it nor any of its officers, directors,
        employees or agents shall be responsible to the Borrower for any act or
        failure to act, except for its own gross negligence or willful
        misconduct.

             (c) The Borrower also authorizes the Lender, at any time and from
        time to time (i) to communicate in its own name with any party to any
        contract or agreement that is a part of the Collateral with regard to
        the assignment of those contracts or agreements hereunder and other
        matters relating thereto and (ii) to execute, in connection with the
        sale provided for in paragraph (b) of Section 8 of this Agreement, any
        endorsements, assignments or other instruments of conveyance or
        transfer with respect to the Collateral.

    7. Performance by the Lender of the Borrower's Obligations. If the Borrower
fails to perform or comply with any of its agreements contained in this
Agreement, and the Lender, as provided for by the terms of this Agreement,
itself performs or complies, or otherwise causes performance or compliance, with
such agreement, the expenses of the Lender incurred in connection with such
performance or compliance, together with interest thereon, shall be payable by
the Borrower to the Lender on demand and shall constitute an Obligation secured
by this Agreement.

    8. Remedies, Rights Upon An Event of Default.

             (a) If an Event of Default shall occur and be continuing:

               (i)  The Borrower shall, upon written request by the Lender,
               notify (and the Borrower hereby authorizes the Lender so to
               notify) each account debtor in respect of any Accounts and
               General Intangible that such Collateral has been assigned to
               the Lender under this Agreement and that any payments due or to
               become due in respect of that Collateral shall be made directly
               to the Lender;

               (ii)  All payments received by the Borrower under or in
               connection with any of the Collateral shall be held by the
               Borrower in trust for the Lender, shall be segregated from
               other funds of the Borrower and shall forthwith upon receipt by
               the Borrower, be turned over to the Lender, in the same form as
               received by the Borrower (duly indorsed by the Borrower to the
               Lender, if required); and

               (iii)  Any and all such payments so received by the Lender
               (whether from the Borrower or otherwise) may, in the sole
               discretion of the Lender, be held by the Lender as collateral
               security for, and then or at any time thereafter applied in
               whole or in part by the Lender, against all or any part of the
               Obligations.

               Any balance of such payments so paid to or held by the Lender
        and remaining after payment in full of all the Obligations shall be
        paid over to the Borrower or to whomsoever may be lawfully entitled to
        receive the same.

             (b) If any Event of Default shall occur and be continuing, the
        Lender may exercise in addition to all other rights and remedies
        granted to it in this Agreement and in any other instrument or
        agreement securing, evidencing or relating to the Obligations, all
        rights and remedies of a secured party under the Code. Without limiting
        the generality of the foregoing, the Borrower expressly agrees that in
        any such event the Lender, without demand of performance or other
        demand, advertisement or notice of any kind (except the notice
        specified below of time and place of public or private sale) to or upon
        the Borrower or any other person (all and each of which demands,
        advertisements and/or notices are hereby expressly waived), may
        forthwith collect, receive appropriate and realize upon the Collateral,

                                       10
<PAGE>

        or any part thereof, and/or may forthwith sell, lease, assign, give
        option or options to purchase, or sell or otherwise dispose of and
        deliver said Collateral (or contract to do so), or any part thereof, in
        one or more parcels at public or private sale or sales, at any exchange
        broker's board or at any of the Lender's offices or elsewhere at such
        prices as it may deem best, for cash or on credit or for future
        delivery without assumption of any credit risk. The Lender shall have
        the right upon any such public sale or sales, and, to the extent
        permitted by law, upon any such private sale or sales, to purchase the
        whole or any part of said Collateral so sold, free of any right or
        equity of redemption in the Borrower, which right or equity is hereby
        expressly released. The Borrower further agrees, at the Lender's
        request, to assemble the Collateral, make it available to the Lender at
        places which the Lender reasonably shall select, whether at the
        Borrower's premises or elsewhere. The Lender shall apply the net
        proceeds of any such collection, recovery, receipt, appropriation,
        realization or sale, after deducting all reasonable costs and expenses
        of every kind incurred therein or incidental to the care, safe keeping
        or otherwise of any or all of the Collateral or in any way relating to
        the rights of the Lender hereunder, including reasonable attorneys'
        fees and legal expenses, to the payment in whole or in part of the
        Obligations, in such order as the Lender may elect, the Borrower
        remaining liable for any deficiency remaining unpaid after such
        application, and only after so paying over such net proceeds and after
        the payment by the Lender of any other amount required by any provision
        of law, need the Lender account for the surplus, if any, to the
        Borrower. To the extent permitted by applicable law, the Borrower
        waives all claims, damages, and demands against the Lender arising out
        of the repossession, retention or sale of the Collateral. The Borrower
        agrees that the Lender need not give more than ten (10) days' notice
        (which notification shall be deemed given when mailed, postage prepaid,
        addressed to the Borrower at its address set forth in Section 10
        hereof) of the time and place of any public sale or of the time after
        which a private sale may take place and that such notice is reasonable
        notification of such matters. The Borrower shall remain liable for any
        deficiency if the proceeds of any sale or disposition of the Collateral
        are insufficient to pay all amounts to which the Lender is entitled,
        the Borrower also being liable for the fees of any attorneys employed
        by the Lender to collect such deficiency.

             (c) The Borrower also agrees to pay all costs of the Lender,
        including attorneys' fees, incurred with respect to the collection of
        any of the Obligations and the enforcement of any of their respective
        rights hereunder.

    9. Limitation on the Lender's Duty in Respect of Collateral. Beyond the safe
custody thereof, the Lender shall not have any duty as to any Collateral in
its possession or control or in the possession or control of any agent or
nominee of it or any income thereon or as to the preservation of rights
against prior parties or any other rights pertaining thereto.

                                       11

postage prepaid:

thereof or the fourth calendar day after such mailing. Either party may change
its address by notice to the other.

    11. Severability. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

    12. No Waiver; Cumulative Remedies. The Lender shall not by any act,
delay, omission or otherwise be deemed to have waived any of its rights or
remedies hereunder and no waiver shall be valid unless in writing, signed by
the Lender, and then only to the extent therein set forth. A waiver by the
Lender of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Lender would otherwise
have had on any future occasion. No failure to exercise nor any delay in
exercising on the part of the Lender, any right, power or privilege hereunder,
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege hereunder preclude any other or future exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies hereunder provided are cumulative and may be exercised singly or
concurrently, and are not exclusive of any rights and remedies provided by
law. None of the terms or provisions of this Agreement may be waived, altered,
modified or amended except by an instrument in writing, duly executed by the
Lender.

    13. Successors and Assigns; Governing Law. This Agreement and all
obligations of the Borrower hereunder shall be binding upon the successors and

the Lender hereunder, inure to the benefit of the Lender and its successors
and assigns. This Agreement shall be governed by, and be construed and
interpreted in accordance with, the laws of the State of New York.

Lender harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all excise, sales or other taxes which may
be payable or determined to be payable with respect to any of the Collateral
or in connection with any of the transactions contemplated by this Agreement.

    15. Termination. When all Obligations have been paid in full and the Total
Commitment has expired or been terminated, this Agreement shall terminate, and
the Lender shall forthwith cause to be assigned, transferred and delivered,
against receipt but without any recourse, warranty or representation
whatsoever, any remaining Collateral and money received in respect of the
Collateral, to or on the order of the Borrower. The Lender shall also execute
and deliver to the Borrower upon that termination such Code termination
statements and such other documentation as is reasonably requested by the
Borrower to effect the termination and release of the liens granted by this
Agreement on the Collateral.

    16. Amendments, Etc. No provision of this Agreement may be waived,
modified or supplemented except by an instrument in writing signed by the
Borrower and the Lender. Any modification, supplement or waiver shall be for
such period and subject to such conditions as shall be specified in the
written instrument effecting the same and shall be binding upon the Lender and
the Borrower, and any such waiver shall be effective only in the specific
instance and for the purpose for which given.

    17. Agreements Superseded. This Agreement supersedes all prior agreements
and understandings, written or oral, among the parties with respect to the
subject matter of this Agreement.

                    FORM OF DEPOSIT ACCOUNT CONTROL AGREEMENT

                        DEPOSIT ACCOUNT CONTROL AGREEMENT

    This DEPOSIT ACCOUNT CONTROL AGREEMENT, dated as of [________] (this
"Agreement"), is entered into between Power Efficiency Corporation, a Delaware
corporation (the "Borrower"), Summit Energy Ventures, LLC, a Delaware limited
liability company (the "Lender"), and [NAME OF DEPOSITARY BANK] (the
"Depositary Bank").

                               W I T N E S S E T H :

    WHEREAS, the Borrower is the Depositary Bank's customer with respect to
the Deposit Accounts (as defined below);

    WHEREAS, the Borrower and the Lender have entered into a Security
Agreement, dated as of May 8, 2003 (the "Security Agreement") pursuant to
which the Borrower has granted to the Lender a continuing security interest
in, among other things, all right, title and interest of the Borrower in, to
and under the Deposit Accounts, whether now owned or existing or hereafter
acquired or arising; and

    WHEREAS, delivery of this Agreement in relation to the Deposit Accounts is
required by the Security Agreement for the purpose of perfecting the Lender's
security interest in, and rights with respect to, the Deposit Accounts;

    NOW, THEREFORE, the parties hereto agree as follows:

    1. Defined Terms; Interpretation.

    (a)  Defined Terms. All references herein to the "Code" refer to the
Uniform Commercial Code as in effect from time to time in the State of New
York. Terms defined in the Code have the same meanings when used in this
Agreement.

    (b) Interpretation. In this Agreement, unless otherwise indicated, the
singular includes the plural and plural the singular; words importing any
gender include the other gender; references to statutes or regulations are to
be construed as including all statutory or regulatory provisions
consolidating, amending or replacing the statute or regulation referred to;
references to "writing" include printing, typing, lithography and other means

                                       20
<PAGE>

of reproducing words in a tangible visible form; the words "including,"
"includes" and "include" are to be deemed to be followed by the words "without
limitation"; references to articles, sections (or subdivisions of sections),
exhibits, annexes or schedules are to this Agreement; references to agreements
and other contractual instruments include all subsequent amendments,
extensions and other modifications to those instruments; and references to
persons include their respective successors and permitted assigns and, in the
case of governmental authorities, persons succeeding to their respective
functions and capacities.

    2. Confirmation of Security. The Borrower hereby confirms that, to secure
the Obligations (as defined in the Security Agreement), it has granted to the
Lender a security interest in all of the Borrower's right, title and interest
in and to each Deposit Account at any time or from time to time established,
all amounts at any time or from time to time in any such Deposit Account, and
all proceeds of all or any part of the foregoing (the "Transaction Lien").

    3. Establishment of Deposit Accounts. The Depositary Bank confirms that:

    (a) the Depositary Bank has established the Deposit Accounts set forth on
Schedule I hereto in the name of the Borrower (such account and any successor
account, the "Deposit Accounts"); and

    (b) the Deposit Account is a "deposit account" as defined in Section 9-
102(a)(29) of the Code.

    4. Instructions. The Depositary Bank agrees to comply with any
instructions originated by the Lender pursuant to Section 10 directing
disposition of funds in the Deposit Accounts without further consent by the
Borrower or any other person. The Borrower consents to the foregoing agreement
by the Depositary Bank.

    5. Waiver of Lien; Waiver of Set-off. The Depositary Bank waives any
security interest, lien or right to make deductions or set-offs that it may
now have or hereafter acquire in or with respect to the Deposit Accounts.
Any amounts credited to the Deposit Accounts will not be subject to deduction,
set-off, banker's lien, or any other right in favor of any person other than
the Lender (except that the Depositary Bank may set off for (a) all items
deposited in and credited to the Deposit Accounts and subsequently returned to
the Depositary Bank unpaid, (b) overdrafts in the Deposit Accounts and
interest thereon, (c) interest and fees (in accordance with the Depositary
Bank's generally applicable account agreements and policies) on any items
deposited in the Deposit Accounts and returned unpaid, and (d) all other
compensation, fees, charges and expenses charged to the Deposit Accounts in
accordance with the Depositary Bank's account roles, policies and normal
banking practices).

                                       21
<PAGE>

    6. Choice of Law. This Agreement shall be construed in accordance with and
governed by the laws of the State of New York. The State of New York shall be
deemed to be the Depositary Bank's jurisdiction for purposes of the Code
(including, without limitation, Section 9-304 thereof).

    7. Conflict with Other Agreements. In the event of any conflict between
this Agreement (or any portion hereof) and any other agreement between the
Depositary Bank and the Borrower with respect to the Deposit Accounts, whether
now existing or hereafter entered into, the terms of this Agreement shall
prevail.

    8. Amendments. No provision of this Agreement may be waived, modified or
supplemented, except by an instrument in writing signed by all the parties to
this Agreement.

    9. Notice of Adverse Claims. Except for the claims and interests of the
Lender and the Borrower, the Depositary Bank does not know of any claim to, or
interest in, the Deposit Accounts.

    10. Maintenance of Deposit Account. In addition to, and not in lieu of,
the obligation of the Depositary Bank to honor instructions as agreed in
Section 2, the Depositary Bank agrees to maintain the Deposit Accounts as
follows: so long as the Depositary Bank has not received a Notice of Exclusive
Control (as defined below), the Depositary Bank may comply with instructions
of the Borrower or any duly authorized agent of the Borrower in respect of the
Deposit Accounts. After the Depositary Bank receives a written notice from the
Lender that it is exercising exclusive control over the Deposit Accounts in
the form of Exhibit A (a "Notice of Exclusive Control"), the Depositary Bank
will cease complying with instructions of the Borrower or any of its agents
and will thereafter comply with the instructions of the Lender, until such
time as the Lender otherwise advises the Depositary Bank in writing.

    11. Successors. This Agreement shall be binding upon, and shall inure to
the benefit of, the parties hereto and their respective successors and
assigns.

    12. Notices. All notices, demands and approvals hereunder shall be in
writing and shall be deemed to have been sufficiently given or served when
presented personally, telecopied or when deposited in the mail with first
class postage prepaid:

and shall be deemed to have been received upon the earlier of actual receipt
thereof or the fourth calendar day after such mailing. Either party may change
its address by notice to the other.

    13. Termination. The rights and powers granted to the Lender under this
Agreement have been granted in order to perfect the Transaction Lien, are powers
coupled with an interest and will not be affected by any bankruptcy of the
Borrower or any lapse of time. The obligations of the Depositary Bank under this
Agreement shall continue in effect until the Lender has notified the Depositary
Bank in writing that the Transaction Lien has been terminated pursuant to the
terms of the Security Agreement. Upon receipt of such notice, the obligations of
the Depositary Bank hereunder with respect to the operation and maintenance of
the Deposit Accounts after the receipt of such notice shall terminate, and the
Lender shall have no further right to originate instructions concerning the
Deposit Accounts and any previous Notice of Exclusive Control delivered by the
Lender shall be deemed to be of no further force and effect.

    14. Indemnity; Depositary Bank's Responsibility. The Borrower agrees to
indemnify, defend and hold harmless the Depositary Bank and its directors,
officers, agents and employees against any loss, liability or expense
(including reasonable fees and disbursements of counsel) incurred in
connection with this Agreement, including any action taken by the Depositary
Bank pursuant to the instructions of the Lender, except to the extent due to
the gross negligence or willful misconduct of the Depositary Bank (as actually
and finally determined by a final, non-appealable judgment of a court of
competent jurisdiction). The Borrower confirms and agrees that the Depositary
Bank shall not have any liability to the Borrower for wrongful dishonor of any
items as a result of any instructions of the Lender. The Lender confirms and
agrees that the Depositary Bank shall not have any liability to the Lender for
executing transactions with respect to the Deposit Accounts at the direction
of the Borrower that are received by the Depositary Bank before the Depositary
Bank receives a Notice of Exclusive Control. The Depositary Bank shall have no
duty to inquire or determine whether the obligations of the Borrower to the

                                       23
<PAGE>

Lender are in default or whether the Lender is entitled to give any such
instructions and the Depositary Bank is fully entitled to rely upon such
instructions from the Lender (even if such instructions are contrary or
inconsistent with any instructions or demands given by the Borrower). The
Depositary Bank may rely on a Notice of Exclusive Control purportedly signed
by the Lender and shall have no duty to investigate or make any determination
as to the validity, genuineness or propriety thereof or the facts giving rise
thereto. This Agreement does not create or impose any obligation or duty upon
the Depositary Bank other than those expressly set forth herein. Without
limiting the generality of the foregoing, the Depositary Bank shall have no
duty or obligation to account to or act on behalf of the Lender with respect
to any other accounts or advise the Lender of the existence of any other
accounts, whether the same are in existence now or are opened after the date
of this Agreement.

    15. Counterparts. This Agreement may be executed in any number of
counterparts, all of which shall constitute but one and the same instrument.
To make proof of this Agreement, it shall only be necessary to produce one
such counterpart (or copy thereof if no such counterpart is available).

            [The remainder of this page is intentionally left blank.
