Exhibit 4.5

                               GREENMAN TECHNOLOGIES, INC.
                                 Note Purchase Agreement

      NOTE PURCHASE AGREEMENT dated as of this 22nd day of December, 2003 (this
"Agreement") between GreenMan Technologies, Inc., a Delaware corporation, with
its principal offices at 7 Kimball lane, Building A, Lynnfield, MA 01940 (the
"Company"), and Jed Schutz (the "Purchaser").

      WHEREAS, on the terms and conditions hereinafter set forth, the Company
desires to sell to Purchaser and Purchaser desires to purchase from the Company,
a 10% Convertible Note due 2004 in the aggregate principal amount of $375,000
(the "Note"), a copy of which is attached to this Agreement as Exhibit A;

      WHEREAS, the Company is offering Units in a private placement to
accredited investors (the "Offering"), on the terms described in the Company's
Confidential Private Placement Memorandum dated December 10, 2003 (the
"Memorandum");

      WHEREAS, the Note is convertible into Conversion Units on the terms and
subject to the conditions further described in the Note; and

      WHEREAS, capitalized terms used and not otherwise defined in this
Agreement shall have the meanings assigned to such terms in the Note.

      NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto do hereby agree as follows:

      I.    PURCHASE AND SALE OF NOTE AND REPRESENTATIONS BY AND COVENANTS OF
            PURCHASER

            1.1 Subject to the terms and conditions hereinafter set forth, the
Purchaser hereby purchases from the Company and the Company hereby sells to the
Purchaser the Note at par (the "Purchase Price"). Concurrently herewith: (i) the
Purchaser is paying the Purchase Price to the Company by wire transfer of
immediately available funds in accordance with the wire transfer instructions
included in Exhibit B to this Agreement and (ii) the Company is delivering the
Note to the Purchaser.

            1.2 The Purchaser recognizes that the purchase of the Note and the
Conversion Units (including the Conversion Shares, the Conversion Warrants and
the Warrant Shares, collectively, the "Securities") involves a high degree of
risk in that (i) the Company will need additional capital but has no assurance
of obtaining additional necessary capital; (ii) an investment in the Company is
highly speculative and only investors who can afford the loss of their entire
investment should consider investing in the Company and the Securities; (iii) an
investor may not be able to liquidate his investment; (iv) transferability of
the Securities is extremely limited; and (v) an investor could sustain the loss
of his entire investment.
<PAGE>

            1.3 The Purchaser represents that he is an "accredited investor" as
such term is defined in Rule 501 of Regulation D promulgated under the
Securities Act of 1933, as amended (the "Act"), and that he is able to bear the
economic risk of an investment in the Securities.

            1.4 The Purchaser acknowledges that he has prior investment
experience, including investment in non-registered securities, or he has
employed the services of an investment advisor, attorney or accountant to read
all of the documents furnished or made available by the Company to him and to
evaluate the merits and risks of such an investment on his behalf, and that he
recognizes the highly speculative nature of this investment.

            1.5 The Purchaser hereby represents that he has been furnished by
the Company during the course of this transaction with all information regarding
the Company which he has requested or desired to know (including the
Memorandum); that all documents which could be reasonably provided have been
made available for his inspection and review; and that he has been afforded the
opportunity to ask questions of and receive answers from duly authorized
officers or other representatives of the Company concerning the terms and
conditions of the Securities, and any additional information which he has
requested.

            1.6 The Purchaser acknowledges that this purchase and sale may
involve tax consequences and that he must retain his own professional advisors
to evaluate the tax and other consequences of an investment in the Securities.

            1.7 The Purchaser acknowledges that this purchase and sale has not
been reviewed by the United States Securities and Exchange Commission ("SEC")
because of the Company's representations that this is intended to be a
non-public offering pursuant to Sections 4(2) or 3(b) of the Act. The Purchaser
represents that the Securities are being purchased for his own account, for
investment and not for distribution or resale to others. The Purchaser agrees
that he will not sell or otherwise transfer the Securities unless they are
registered under the Act or unless an exemption from such registration is
available.

            1.8 The Purchaser understands that the Securities have not been
registered under the Act by reason of a claimed exemption under the provisions
of the Act which depends, in part, upon his investment intention. In this
connection, the Purchaser understands that it is the position of the SEC that
the statutory basis for such exemption would not be present if his
representation merely meant that his present intention was to hold such
securities for a short period, such as the capital gains period of tax statutes,
for a deferred sale, for a market rise, or for any other fixed period. The
Purchaser realizes that, in the view of the SEC, a purchase now with an intent
to distribute would represent a purchase with an intent inconsistent with his
representation to the Company, and the SEC might regard such a distribution as a
deferred sale to which such exemption is not available.


                                       2
<PAGE>

            1.9 The Purchaser understands that Rule 144 promulgated under the
Act requires, among other conditions, a one-year holding period prior to the
resale (in limited amounts) of securities acquired in a non-public offering
without having to satisfy the registration requirements under the Act. The
Purchaser consents that the Company may, if it desires, permit the transfer of
the Securities out of his name only when his request for transfer is accompanied
by an opinion of counsel reasonably satisfactory to the Company that neither the
sale nor the proposed transfer results in a violation of the Act or any
applicable state "blue sky" laws (collectively, the "Securities Laws"). The
Purchaser agrees to hold the Company and its directors, officers and controlling
persons and their respective heirs, representatives, successors and assigns
harmless and to indemnify them against all liabilities, costs and expenses
incurred by them as a result of any misrepresentation made by him contained
herein or any sale or distribution of the Securities by the Purchaser in
violation of any Securities Laws. The Purchaser acknowledges that at such time,
if ever, as any of the Securities are registered, sales of such Securities will
be subject to state securities laws, including those of states which may require
any securities sold therein to be sold through a registered broker-dealer or in
reliance upon an exemption from registration.

            1.10 The Purchaser consents to the placement of one or more legends
on any certificate or other document evidencing the Securities stating that they
have not been registered under the Act and setting forth or referring to the
restrictions on transferability and sale thereof.

            1.11 The Purchaser hereby represents that, except as set forth in
this Agreement, no representations or warranties have been made to the Purchaser
by the Company or any agent, employee or affiliate of the Company, and in
entering into this transaction the Purchaser is not relying on any information
other than that contained in this Agreement and the results of independent
investigation by the Purchaser.

      II.   REPRESENTATIONS BY THE COMPANY

            The Company represents and warrants to the Purchaser that:

            2.1 The Company is a corporation duly organized, existing and in
good standing under the laws of the State of Delaware and has the corporate
power to conduct the business which it conducts and proposes to conduct.

            2.2 The execution, delivery and performance of this Agreement by the
Company has been duly approved by the Board of Directors of the Company and all
other actions required to authorize and effect the purchase and sale of the
Securities has been duly taken and approved.

            2.3 The Securities have been duly and validly authorized and, upon
conversion of the Note (i) after the issuance of the Conversion Shares, such
Conversion Shares will be fully paid and non-assessable and (ii) when issued and
paid for in accordance with the Conversion Warrants, the Warrant Shares will be
fully paid and non-assessable.


                                       3
<PAGE>

            2.4 The Company has obtained, or is in the process of obtaining, all
licenses, permits and other governmental authorizations necessary to the conduct
of its business; such licenses, permits and other governmental authorizations
obtained are in full force and effect; and the Company is in all material
respects complying therewith.

            2.5 The Company knows of no pending or threatened legal or
governmental proceedings to which the Company is a party and which could
materially adversely affect the business, property, financial condition or
operations of the Company.

            2.6 The Company is not in violation of, or default under, nor will
the execution and delivery of this Agreement, the issuance of the Securities and
the incurrence of the obligations herein set forth and the consummation of the
transactions herein contemplated, result in a violation of, or constitute a
default under, the Company's Certificate of Incorporation or Bylaws, in the
performance or observance of any material obligation, agreement, covenant or
condition contained in any bond, debenture, note or other evidence of
indebtedness or in any material contract, indenture, mortgage, loan agreement,
lease, joint venture or other agreement or instrument, to which the Company is a
party or by which it or any of its properties may be bound, or in violation of
any material order, rule, regulation, writ, injunction or decree of any
government, governmental instrumentality or court, domestic or foreign.

      III.  REGISTRATION RIGHTS

            3.1 Demand Registration. Unless the Company closes a sale of Units
in the Offering prior to such date, beginning on February 11, 2004 (the "Target
Date") (which date may be extended by the Company and the placement agent in the
Offering for a period not to exceed 30 days), the Purchaser may make a written
request to the Company to register, and the Company shall register, under the
Act (a "Demand Registration"), the number of Conversion Shares and/or Warrant
Shares stated in such request; provided, however, that the Company shall not be
obligated to effect more than one such Demand Registration for the Purchaser.

            3.2 Piggy-Back Registration. In the event that the Company closes a
sale of Units in the Offering prior to the Target Date: (i) the Purchaser shall
be entitled to the same registration rights as the subscribers of Units in the
Offering on the terms and subject to the conditions set forth in that certain
Registration Rights Agreement included as Exhibit B to the Memorandum and (ii)
the provisions of this Article III shall have no further force or effect.

            3.3 Registration Procedures. In connection with any registration
statement in which the Conversion Shares and/or Warrant Shares are included, the
Company shall:

            (a) use its best efforts to cause such registration statement to
become and remain effective;

            (b) prepare and file with the SEC such amendments to such
registration statement and supplements to the prospectus contained therein as
may be necessary to keep such registration statement effective;


                                       4

such securities;

            (d) use its best efforts to register or qualify the securities
covered by such registration statement under the state securities or blue sky
laws of such jurisdictions as the Purchaser may reasonably request in writing
within 20 days following the original filing of such registration statement,
except that the Company shall not for any purpose be required to execute a
general consent to service of process or to qualify to do business as a foreign
corporation in any jurisdiction wherein it is not so qualified;

            (e) notify the Purchaser, promptly after it shall receive notice
thereof, of the time when such registration statement has become effective or a

            (g) prepare and file with the SEC, promptly upon the request of the
Purchaser, any amendments or supplements to such registration statement or

by counsel for the Company), is required under the Act or the rules and
regulations thereunder in connection with the distribution of Conversion Shares
and/or Warrant Shares by the Purchaser;

            (h) prepare and promptly file with the SEC, and promptly notify the
Purchaser of the filing of, any amendment or supplement to such registration
statement or prospectus as may be necessary to correct any statements or
omissions if, at the time when a prospectus relating to such securities is
required to be delivered under the Act, any event shall have occurred as the
result of which any such prospectus or any other prospectus as then in effect
includes or would include an untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances in which they were made, not misleading; and

            (i) advise the Purchaser, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the SEC
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for that purpose and promptly use its best efforts
to prevent the issuance of any stop order or to obtain its withdrawal if such
stop order should be issued.

            3.4 Expenses. (a) All fees, costs and expenses of the Purchaser in
connection with participation in a registration pursuant to this Article III (as
specified in paragraph (b) below) shall be borne by the Company, provided,
however, that the Purchaser shall bear its pro-rata share of the underwriting
discount and commissions and transfer taxes and the cost of its own counsel.

<PAGE>

Company as provided in paragraph (a) above shall include, without limitation,
all registration, filing, and NASD fees, printing expenses, fees and

laws of any jurisdictions in which the securities to be offered are to be
registered and qualified (except as provided in subparagraph (a) above). Fees
and disbursements of counsel and accountants for the Purchaser and any other
expenses incurred by the Purchaser not expressly included above shall be borne
by the Purchaser.

            3.5 Indemnification. (a) The Company will indemnify and hold
harmless the Purchaser, its directors and officers, and any underwriter (as
defined in the Act) for the Purchaser and each person, if any, who controls the
Purchaser or such underwriter within the meaning of the Act (collectively the
"Indemnified Purchaser"), from and against, and will reimburse such Indemnified
Purchaser with respect to, any and all loss, damage, liability, cost and expense
to which such Indemnified Purchaser may become subject under the Securities Act
or otherwise, insofar as such losses, damages, liabilities, costs or expenses
are caused by, arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
effecting a registration hereunder, any prospectus contained therein or any
amendment or supplement thereto, or the omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, damage, liability, cost or expense is caused by,
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission so made in conformity with information furnished
by or on behalf of such Indemnified Purchaser in writing specifically for use in
the preparation thereof.

            (b) The Purchaser will indemnify and hold harmless the Company, its
directors and officers, any controlling person and any underwriter from and
against, and will reimburse the Company, its directors and officers, any
controlling person and any underwriter with respect to, any and all loss,
damage, liability, cost or expense to which the Company or any controlling
person and/or any underwriter may become subject under the Act or otherwise,
insofar as such losses, damages, liabilities, costs or expenses are caused by,
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any registration statement effecting a
registration hereunder, any prospectus contained therein or any amendment or
supplement thereto, or the omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was so made in reliance upon
and in strict conformity with written information furnished by or on behalf of
the Purchaser specifically for use in the preparation thereof; provided,
however, that the obligations of the Purchaser hereunder shall be limited to an
amount equal to the net proceeds paid to the Purchaser under such registration
statement.


                                       6
<PAGE>

            (c) Promptly after receipt by an indemnified party pursuant to the
provisions of paragraph (a) or (b) of this Section 3.5 of notice of the
commencement of any action involving the subject matter of the foregoing
indemnity provisions such indemnified party will, if a claim thereof is to be
made against the indemnifying party pursuant to the provisions of said paragraph
(a) or (b), promptly notify the indemnifying party of the commencement thereof;
but the omission to so notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than
hereunder and will not relieve it from any liability hereunder except to the
extent that such failure results in the forfeiture by the indemnifying party of
substantial rights or defenses. In case such action is brought against an
indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party shall have the right to participate in, and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party, provided, however, if counsel for the indemnifying party
concludes that a single counsel cannot under applicable legal and ethical
considerations, represent both the indemnifying party and the indemnified party,
the indemnified party or parties have the right to select separate counsel to
participate in the defense of such action on behalf of such indemnified party or
parties. After notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party will not
be liable to such indemnified party pursuant to the provisions of said paragraph
(a) or (b) for any legal or other expense subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation, unless (i) the indemnified party shall have employed
counsel in accordance with the provisions of the preceding sentence, (ii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after the notice of the commencement of the action or (iii) the
indemnifying party has, in its sole discretion, authorized the employment of
counsel for the indemnified party at the expense of the indemnifying party.
