            (a) On or prior to each Filing Date, the Company shall prepare and
file with the Commission a Registration Statement covering the Registrable
Securities for a selling stockholder resale offering to be made on a continuous
basis pursuant to Rule 415. Each Registration Statement shall be on Form S-3
(except if the Company is not then eligible to register for resale the
Registrable Securities on Form S-3, in which case such registration shall be on
another appropriate form in accordance herewith). The Company shall cause each
Registration Statement to become effective and remain effective as provided
herein. The Company shall use its best efforts to cause each Registration
Statement to be declared effective under the Securities Act as promptly as
possible after the filing thereof, but in any event no later than the
Effectiveness Date. The Company shall use its reasonable commercial efforts to
keep each Registration Statement continuously effective under the Securities Act
until the date which is the earlier date of when (i) all Registrable Securities
covered by such Registration Statement have been sold or (ii) all Registrable
Securities covered by such Registration Statement may be sold immediately
without registration under the Securities Act and without volume restrictions
pursuant to Rule 144(k), as determined by the counsel to the Company pursuant to
a written opinion letter to such effect, addressed and acceptable to the
Company's transfer agent and the affected Holders (each, an "Effectiveness
Period").

            (b) Within three business days of the Effectiveness Date, the
Company shall cause its counsel to issue a blanket opinion in the form attached
hereto as Exhibit A, to the transfer agent stating that the shares are subject
to an effective registration statement and can be reissued free of restrictive
legend upon notice of a sale by the Purchaser and confirmation by the Purchaser
that it has complied with the prospectus delivery requirements, provided that
the Company has not advised the transfer agent orally or in writing that the
opinion has been withdrawn. Copies of the blanket opinion required by this
Section 2(b) shall be delivered to the Purchaser within the time frame set forth
above.

      3. Registration Procedures. If and whenever the Company is required by the
provisions hereof to effect the registration of any Registrable Securities under
the Securities Act, the Company will, as expeditiously as possible:

            (a) prepare and file with the Commission a Registration Statement
with respect to such Registrable Securities, respond as promptly as possible to
any comments received from the Commission, and use its best efforts to cause
such Registration Statement to become and remain effective for the Effectiveness
Period with respect thereto, and promptly provide to the Purchaser copies of all
filings and Commission letters of comment relating thereto;

            (b) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the Prospectus used in connection
therewith as may be necessary to comply with the provisions of the Securities
Act with respect to the disposition of all Registrable Securities covered by
such Registration Statement and to keep such Registration Statement effective
until the expiration of the Effectiveness Period applicable to such Registration
Statement;


                                        3
<PAGE>

            (c) furnish to the Purchaser such number of copies of the
Registration Statement and the Prospectus included therein (including each
preliminary Prospectus) as the Purchaser reasonably may request to facilitate
the public sale or disposition of the Registrable Securities covered by such
Registration Statement;

            (d) use its commercially reasonable efforts to register or qualify
the Purchaser's Registrable Securities covered by such Registration Statement
under the securities or "blue sky" laws of such jurisdictions within the United
States as the Purchaser may reasonably request, provided, however, that the
Company shall not for any such purpose be required to qualify generally to
transact business as a foreign corporation in any jurisdiction where it is not
so qualified or to consent to general service of process in any such
jurisdiction;

            (e) list the Registrable Securities covered by such Registration
Statement with any securities exchange on which the Common Stock of the Company
is then listed;

            (f) immediately notify the Purchaser at any time when a Prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event of which the Company has knowledge as a result of which
the Prospectus contained in such Registration Statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing; and

            (g) make available for inspection by the Purchaser and any attorney,
accountant or other agent retained by the Purchaser, all publicly available,
non-confidential financial and other records, pertinent corporate documents and
properties of the Company, and cause the Company's officers, directors and
employees to supply all publicly available, non-confidential information
reasonably requested by the attorney, accountant or agent of the Purchaser.

      4. Registration Expenses. All expenses relating to the Company's
compliance with Sections 2 and 3 hereof, including, without limitation, all
registration and filing fees, printing expenses, fees and disbursements of
counsel and independent public accountants for the Company, fees and expenses
(including reasonable counsel fees) incurred in connection with complying with
state securities or "blue sky" laws, fees of the NASD, transfer taxes, fees of
transfer agents and registrars, fees of, and disbursements incurred by, one
counsel for the Holders are called "Registration Expenses". All selling
commissions applicable to the sale of Registrable Securities, including any fees
and disbursements of any special counsel to the Holders beyond those included in
Registration Expenses, are called "Selling Expenses." The Company shall only be
responsible for all Registration Expenses.

      5. Indemnification.

            (a) In the event of a registration of any Registrable Securities
under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless each Holder, and its officers, directors and each other
person, if any, who controls such Holder within the meaning of the Securities
Act, against any losses, claims, damages or liabilities, joint or several, to
which such Holder, or such persons may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions


                                        4
<PAGE>

in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any Registration
Statement under which such Registrable Securities were registered under the
Securities Act pursuant to this Agreement, any preliminary Prospectus or final
Prospectus contained therein, or any amendment or supplement thereof, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse such Holder, and each such person for
any reasonable legal or other expenses incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the Company will not be liable in any such case if and
to the extent that any such loss, claim, damage or liability 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 the Purchaser or any such person in writing specifically for use in
any such document.

            (b) In the event of a registration of the Registrable Securities
under the Securities Act pursuant to this Agreement, the Purchaser will
indemnify and hold harmless the Company, and its officers, directors and each
other person, if any, who controls the Company within the meaning of the
Securities Act, against all losses, claims, damages or liabilities, joint or
several, to which the Company or such persons may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact which was
furnished in writing by the Purchaser to the Company expressly for use in (and
such information is contained in) the Registration Statement under which such
Registrable Securities were registered under the Securities Act pursuant to this
Agreement, any preliminary Prospectus or final Prospectus contained therein, or
any amendment or supplement thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse the Company and each such person for any reasonable legal or
other expenses incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action, provided, however, that the
Purchaser will be liable in any such case if and only to the extent that any
such loss, claim, damage or liability 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 in writing to the Company by or on behalf
of the Purchaser specifically for use in any such document. Notwithstanding the
provisions of this paragraph, the Purchaser shall not be required to indemnify
any person or entity in excess of the amount of the aggregate net proceeds
received by the Purchaser in respect of Registrable Securities in connection
with any such registration under the Securities Act.

            (c) Promptly after receipt by a party entitled to claim
indemnification hereunder (an "Indemnified Party") of notice of the commencement
of any action, such Indemnified Party shall, if a claim for indemnification in
respect thereof is to be made against a party hereto obligated to indemnify such
Indemnified Party (an "Indemnifying Party"), notify the Indemnifying Party in
writing thereof, but the omission so to notify the Indemnifying Party shall not
relieve it from any liability which it may have to such Indemnified Party other
than under this Section 5(c) and shall only relieve it from any liability which
it may have to such Indemnified Party under this Section 5(c) if and to the
extent the Indemnifying Party is prejudiced by such omission. In case any such
action shall be brought against any Indemnified Party and it shall notify the


                                        5
<PAGE>

Indemnifying Party of the commencement thereof, the Indemnifying Party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such Indemnified
Party, and, after notice from the Indemnifying Party to such Indemnified Party
of its election so to assume and undertake the defense thereof, the Indemnifying
Party shall not be liable to such Indemnified Party under this Section 5(c) for
any legal expenses subsequently incurred by such Indemnified Party in connection
with the defense thereof; if the Indemnified Party retains its own counsel, then
the Indemnified Party shall pay all fees, costs and expenses of such counsel,
provided, however, that, if the defendants in any such action include both the
Indemnified Party and the Indemnifying Party and the Indemnified Party shall
have reasonably concluded that there may be reasonable defenses available to it
which are different from or additional to those available to the Indemnifying
Party or if the interests of the Indemnified Party reasonably may be deemed to
conflict with the interests of the Indemnifying Party, the Indemnified Party
shall have the right to select one separate counsel and to assume such legal
defenses and otherwise to participate in the defense of such action, with the
reasonable expenses and fees of such separate counsel and other expenses related
to such participation to be reimbursed by the Indemnifying Party as incurred.


            (d) In order to provide for just and equitable contribution in the
event of joint liability under the Securities Act in any case in which either
(i) the Purchaser, or any officer, director or controlling person of the
Purchaser, makes a claim for indemnification pursuant to this Section 5 but it
is judicially determined (by the entry of a final judgment or decree by a court
of competent jurisdiction and the expiration of time to appeal or the denial of
the last right of appeal) that such indemnification may not be enforced in such
case notwithstanding the fact that this Section 5 provides for indemnification
in such case, or (ii) contribution under the Securities Act may be required on
the part of the Purchaser or such officer, director or controlling person of the
Purchaser in circumstances for which indemnification is provided under this
Section 5; then, and in each such case, the Company and the Purchaser will
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject (after contribution from others) in such proportion so that the
Purchaser is responsible only for the portion represented by the percentage that
the public offering price of its securities offered by the Registration
Statement bears to the public offering price of all securities offered by such
Registration Statement, provided, however, that, in any such case, (A) the
Purchaser will not be required to contribute any amount in excess of the public
offering price of all such securities offered by it pursuant to such
Registration Statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 10(f) of the Act) will be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

      6. Representations and Warranties.

            (a) The Common Stock is registered pursuant to Section 12(b) or
12(g) of the Exchange Act and, except with respect to certain matters which the
Company has disclosed to the Purchaser on Schedule 12(u) to the Security
Agreement, the Company has timely filed all proxy statements, reports,
schedules, forms, statements and other documents required to be filed by it
under the Exchange Act. The Company has filed (i) its Annual Report on Form
10-KSB for the fiscal year ended September 30, 2005 and (ii) its Quarterly
Report on Form 10-QSB for its fiscal quarter ended December 31, 2005 and March
31, 2006 (collectively, the "SEC Reports"). Each SEC Report was, at the time of


                                        6
<PAGE>

its filing, in substantial compliance with the requirements of its respective
form and none of the SEC Reports, nor the financial statements (and the notes
thereto) included in the SEC Reports, as of their respective filing dates,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. The
financial statements of the Company included in the SEC Reports comply as to
form in all material respects with applicable accounting requirements and the
published rules and regulations of the Commission or other applicable rules and
regulations with respect thereto. Such financial statements have been prepared
in accordance with generally accepted accounting principles ("GAAP") applied on
a consistent basis during the periods involved (except (i) as may be otherwise
indicated in such financial statements or the notes thereto or (ii) in the case
of unaudited interim statements, to the extent they may not include footnotes or
may be condensed) and fairly present in all material respects the financial
condition, the results of operations and the cash flows of the Company and its
subsidiaries, on a consolidated basis, as of, and for, the periods presented in
each such SEC Report.

            (b) The Common Stock is quoted for trading on the NASDAQ Over The
Counter Bulletin Board and satisfies all requirements for the continuation of
such listing, and the Company shall do all things necessary for the continuation
of such listing. The Company has not received any notice that its Common Stock
will no longer be quoted on the NASDAQ Over The Counter Bulletin Board (except
for prior notices which have been fully remedied) or that the Common Stock does
not meet all requirements for the continuation of such listing

            (c) Neither the Company, nor any of its affiliates, nor any person
acting on its or their behalf, has directly or indirectly made any offers or
sales of any security or solicited any offers to buy any security under
circumstances that would cause the offering of the Securities pursuant to the
Security Agreement to be integrated with prior offerings by the Company for
purposes of the Securities Act which would prevent the Company from selling the
Common Stock pursuant to Rule 506 under the Securities Act, or any applicable
exchange-related stockholder approval provisions, nor will the Company or any of
its affiliates or subsidiaries take any action or steps that would cause the
offering of the Common Stock to be integrated with other offerings (other than
such concurrent offering to the Purchaser).

            (d) The Warrants and the shares of Common Stock that the Purchaser
may acquire pursuant to the Warrants are all restricted securities under the
Securities Act as of the date of this Agreement. The Company will not issue any
stop transfer order or other order impeding the sale and delivery of any of the
Registrable Securities at such time as such Registrable Securities are
registered for public sale or an exemption from registration is available,
except as required by federal or state securities laws.

            (e) The Company understands the nature of the Registrable Securities
issuable upon the exercise of each Warrant and recognizes that the issuance of
such Registrable Securities may have a potential dilutive effect. The Company
specifically acknowledges that its obligation to issue the Registrable
Securities is binding upon the Company and enforceable regardless of the
dilution such issuance may have on the ownership interests of other shareholders
of the Company.


                                        7
<PAGE>

            (f) Except for agreements made in the ordinary course of business,
there is no agreement that has not been filed with the Commission as an exhibit
to a registration statement or to a form required to be filed by the Company
under the Exchange Act, the breach of which could reasonably be expected to have
a material and adverse effect on the Company and its subsidiaries, or would
prohibit or otherwise interfere with the ability of the Company to enter into
and perform any of its obligations under this Agreement in any material respect.

            (g) The Company will at all times have authorized and reserved a
sufficient number of shares of Common Stock for the full exercise of the
Warrants.

      7. Miscellaneous.

            (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their respective obligations under this Agreement, each Holder
or the Company, as the case may be, in addition to being entitled to exercise
all rights granted by law and under this Agreement, including recovery of
damages, will be entitled to specific performance of its rights under this
Agreement.

            (b) No Piggyback on Registrations. Except as and to the extent set
forth on Schedule 7(b) hereto, neither the Company nor any of its security
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in any Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right for inclusion of shares in the
Registration Statement to any of its security holders. Except as and to the
extent specified in Schedule 7(b) hereto, the Company has not previously entered
into any agreement granting any registration rights with respect to any of its
securities to any Person that have not been fully satisfied.

            (c) Compliance. Each Holder covenants and agrees that it will comply
with the prospectus delivery requirements of the Securities Act as applicable to
it in connection with sales of Registrable Securities pursuant to any
Registration Statement.

            (d) Discontinued Disposition. Each Holder agrees by its acquisition
of such Registrable Securities that, upon receipt of a notice from the Company
of the occurrence of a Discontinuation Event (as defined below), such Holder
will forthwith discontinue disposition of such Registrable Securities under the
applicable Registration Statement until such Holder's receipt of the copies of
the supplemented Prospectus and/or amended Registration Statement or until it is
advised in writing (the "Advice") by the Company that the use of the applicable
Prospectus may be resumed, and, in either case, has received copies of any
additional or supplemental filings that are incorporated or deemed to be
incorporated by reference in such Prospectus or Registration Statement. The
Company may provide appropriate stop orders to enforce the provisions of this
paragraph. For purposes of this Agreement, a "Discontinuation Event" shall mean
(i) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement (the Company shall provide true and complete copies
thereof and all written responses thereto to each of the Holders); (ii) any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to such Registration Statement or Prospectus or
for additional information; (iii) the issuance by the Commission of any stop


                                        8
<PAGE>

order suspending the effectiveness of such Registration Statement covering any
or all of the Registrable Securities or the initiation of any Proceedings for
that purpose; (iv) the receipt by the Company of any notification with respect
to the suspension of the qualification or exemption from qualification of any of
the Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose; and/or (v) the occurrence of any
event or passage of time that makes the financial statements included in such
Registration Statement ineligible for inclusion therein or any statement made in
such Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to such Registration Statement, Prospectus or other
documents so that, in the case of such Registration Statement or Prospectus, as
the case may be, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

            (e) Piggy-Back Registrations. If at any time during any
Effectiveness Period there is not an effective Registration Statement covering
all of the Registrable Securities required to be covered during such
Effectiveness Period and the Company shall determine to prepare and file with
the Commission a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, then the Company shall send to each Holder written notice of such
determination and, if within fifteen (15) days after receipt of such notice, any
such Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
Holder requests to be registered, to the extent the Company may do so without
violating registration rights of others which exist as of the date of this
Agreement, subject to customary underwriter cutbacks applicable to all holders
of registration rights and subject to obtaining any required consent of any
selling stockholder(s) to such inclusion under such registration statement.

            (f) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of the then outstanding Registrable Securities. Notwithstanding
the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of certain Holders
and that does not directly or indirectly affect the rights of other Holders may
be given by Holders of at least a majority of the Registrable Securities to
which such waiver or consent relates; provided, however, that the provisions of
this sentence may not be amended, modified, or supplemented except in accordance
with the provisions of the immediately preceding sentence.

            (g) Notices. Any notice or request hereunder may be given to the
Company or the Purchaser at the respective addresses set forth below or as may
hereafter be specified in a notice designated as a change of address under this
Section 7(g). Any notice or request hereunder shall be given by registered or

the Company acknowledge that any appeals from those courts may have to be heard

illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative

      Re:   GreenMan Technologies, Inc. Registration Statement on Form [S-3]

Ladies and Gentlemen:

      As counsel to GreenMan Technologies, Inc., a Delaware corporation (the
"Company"), we have been requested to render our opinion to you in connection
with the resale by the individuals or entitles listed on Schedule A attached
hereto (the "Selling Stockholders"), of an aggregate of __________ shares (the
"Shares") of the Company's Common Stock.

      A Registration Statement on Form [S-3] under the Securities Act of 1933,
as amended (the "Act"), with respect to the resale of the Shares was declared
effective by the Securities and Exchange Commission on [date]. Enclosed is the
Prospectus dated [date]. We understand that the Shares are to be offered and
sold in the manner described in the Prospectus.

      Based upon the foregoing, upon request by the Selling Stockholders at any
time while the registration statement remains effective, it is our opinion that
the Shares have been registered for resale under the Act and new certificates
evidencing the Shares upon their transfer or re-registration by the Selling
Stockholders may be issued without restrictive legend. We will advise you if the
registration statement is not available or effective at any point in the future.

                                   Very truly yours,
