Item 2. Acquisition or Disposition of Assets

         On  April  18,  1997,  GreenMan  Technologies,   Inc.  (the  "Company")
announced that it had signed a letter of intent with Browning Ferris Industries,
Inc.  ("BFI") of Houston,  Texas to purchase  all of the issued and  outstanding
stock of BFI's tire  recycling  subsidiaries  located in  Jackson,  Georgia  and
Savage,  Minnesota and to purchase  certain tire  processing  related  assets at
BFI's  Asuza,  California  facility  (hereinafter  the purchase of the stock and
assets is referred to as the  "Acquisition").  The letter of intent also granted
the Company an exclusive  option to purchase  BFI's Ford Heights,  Illinois tire
recycling assets.

         Upon  the  closing  of  the  Acquisition,  of  which  there  can  be no
assurance, the Company will pay BFI the sum of $4,850,000 in cash plus an amount
equal to the accounts receivable and inventory as shown on the balance sheets of
the three  operations.  The Company has already  paid  $100,000 to BFI as a good
faith deposit  against the purchase  price and will pay an  additional  $550,000
upon signing of the definitive Purchase and Sale Agreement.  The Closing,  which
is subject to legal and  financial  due  diligence by the Company is expected to
occur in June 1997.

Item 5. Other Events

         On April 21,  1997,  (the  "First  Closing")  and  April 30,  1997 (the
"Second  Closing"),  in  reliance  upon the  transaction  exemption  afforded by
Regulation D  ("Regulation  D") as  promulgated  by the  Securities and Exchange
Commission, under the Securities Act of 1933, as amended, GreenMan Technologies,
Inc. (the  "Company")  completed the sale of its  Convertible  Notes due October
1998 (the "Notes") in the aggregate principal amount of $1,500,000.

         The Notes are  convertible,  at any time  commencing  60 days after the
date of  issuance  and on or  before  one year from the date of  issuance,  into
shares of the  Company's  common  stock,  $.01 par value per share (the  "Common
Stock"),  at a conversion  price per share equal to seventy percent (70%) of the
average of the closing  bid prices of the Common  Stock as reported by NASDAQ on
the five  trading  days  immediately  preceding  the date on which  such Note is
converted into Common Stock,  provided  however,  that the conversion  price per
share shall be no greater than  seventy  (70%) of the average of the closing bid
prices  of  Common  Stock  as  reported  by  NASDAQ  on the  five  trading  days
immediately  preceding the date of issuance of the Notes. Upon conversion of the
Notes,  the Holder will also receive 400 shares of Common Stock for each $10,000
of principal converted in payment of any and all interest on the Note.

         In connection  with the sale of the Notes,  the Company  issued to each
purchaser  a warrant to  purchase  one share of Common  Stock for every $5.00 of
principal of Notes  purchased by such  investor (the  "Warrants").  In the First
Closing,  the Company issued Warrants to purchase an aggregate of 210,000 shares
exercisable at $1.00 per Warrant and in the Second  Closing,  the Company issued
Warrants to purchase an aggregate of 90,000  shares  exercisable  at $.96875 per
warrant. Each Warrant expires two years from the date of issuance thereof.

         H.J.  Meyers & Co.,  Inc.  acted as  placement  agent  (the  "Placement
Agent") in the sale of the Notes and the  Warrants  and  received  an  aggregate
placement fee equal to $150,000.  In addition,  the Placement  Agent received an
aggregate  of  $45,000  as a  non-accountable  expense  allowance.  Warrants  to
purchase 150,000 shares exercisable at $.96875 were also issued to the Placement
Agent and its designees.

         7. Conditions Precedent to the Company's  Obligations.  The obligations
of the Company  hereunder are subject to the performance by the Purchaser of its
obligations  hereunder and to the  satisfaction of the condition  precedent that
the  representations  and  warranties  made by the  Purchaser in this  Agreement
shall,  unless  waived  by the  Company,  be true and  correct  in all  material
respects as of the date hereof and at the Closing Date,  with the same force and
effect as if they had been made on and as of the Closing Date.

         8. Transfer of Securities.

              (a) Securities Act Legend.  Each certificate  evidencing the Note,
the Note Shares,  the Warrant,  the Warrant Shares and any  certificates  issued
upon  transfer  or  exchange of the Note,  the Note  Shares,  the Warrant or the
Warrant  Shares shall be stamped or  imprinted  with a legend  substantially  as
follows:

      THE  SECURITIES  REPRESENTED  HEREBY  HAVE NOT BEEN  REGISTERED  UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED,  OR UNDER THE  SECURITIES  LAWS OF ANY
      STATE; AND MAY NOT BE SOLD,  ASSIGNED,  TRANSFERRED,  PLEDGED OR OTHERWISE
      DISPOSED OF EXCEPT IN COMPLIANCE  WITH, OR PURSUANT TO AN EXEMPTION  FROM,
      THE REQUIREMENTS OF SUCH ACT OR SUCH LAWS.

              (b)  Securities  Act  Compliance.  Each holder (a  "Holder")  of a
certificate  evidencing  the Note,  the Note Shares,  the Warrant or the Warrant
Shares which bears the  restrictive  legend set forth in Section 8(a) above (the
"Restricted  Securities"),  and who  proposes to Transfer (as defined in Section
3(a) of this Agreement) any Restricted Securities,  shall give written notice to
the Company of such Holder's intention to effect such Transfer. Each such notice
shall  describe  the  manner and  circumstances  of the  proposed  sale or other
disposition  in sufficient  detail and may be accompanied by an opinion of legal
counsel to the Holder.  Promptly upon receipt of such notice,  the Company shall
present a copy thereof (together with any

                                       -7-



<PAGE>



accompanying  opinion of legal counsel to the Holder) to its legal counsel,  and
the following provisions shall apply:

                 (i) If,  in the  opinion  of  legal  counsel  to  such  Holder,
satisfactory  in form and substance to the Company and its legal counsel,  or if
such notice was not  accompanied  by an opinion of legal  counsel to the Holder,
then,  if, in the opinion of legal counsel to the Company,  the proposed sale or
other disposition may be effected without registering the Restricted  Securities
involved under the Securities Act or under state  securities  laws,  such Holder
shall be entitled to Transfer such Restricted  Securities in accordance with the
terms of the notice  delivered  to the  Company.  The  Company  will  advise the
Holder,  within five (5) business days after submission of such notice,  whether
such Holder is entitled to so Transfer the Restricted Securities.  If the Holder
is  entitled  to  so  Transfer,   he  shall  submit  the  stock  certificate  or
certificates  evidencing  the  Restricted  Securities to be  Transferred  to the
Company in proper form for Transfer and  accompanied by appropriate  instruments
of  Transfer.   Restricted   Securities  thus   Transferred  (and  each  of  the
certificates  evidencing  any  untransferred  balance of the  Securities  not so
transferred)  shall  bear the  restrictive  legend  set forth in  Section  8(a),
unless,  in the  opinion of both such  legal  counsel  (or legal  counsel to the
Company  if the Holder did not  present an opinion of its legal  counsel),  such
legend is not required by the  applicable  provisions of the  Securities  Act or
state securities laws; and

                 (ii) If in the  reasonable  opinion  of  either  of such  legal
counsel  (or legal  counsel to the  Company  if the  Holder  did not  present an
opinion of its legal counsel),  the proposed Transfer cannot be effected without
registering the Securities involved under the Securities Act or state securities
laws,  such  Holder  shall not offer to Transfer  or  Transfer  such  Restricted
Securities  unless and until such  Restricted  Securities  have been  registered
under  the  Securities  Act or state  securities  laws for  such  purpose  or an
exemption from such registration  becomes available  pursuant to Section 8(b)(i)
above.  The Company  has  obligated  itself to register  the Note Shares and the
Warrant Shares pursuant to the terms of the  Registration  Rights  Agreement,  a
copy of which is attached hereto and made a part hereof.

         9. Fees and Expenses.  Each of the Purchaser and the Company  agrees to
pay its own expenses  incident to the performance of its obligations  hereunder,
including,  but not limited to, the fees,  expenses  and  disbursements  of such
party's counsel.

         10. Survival of the  Representations.  Warranties.  etc. The respective
agreements,  representations,  warranties, indemnities and other statements made
by or on behalf of the Company and the Purchaser, respectively, pursuant to this
Agreement,   shall  remain  in  full  force  and  effect,   regardless   of  any
investigation  made by or on behalf of the other party to this  Agreement or any
officer,  director or employee of, or person controlling or under common control
with, such party and will survive delivery of any payment for the Securities.

constitutes  the sole and entire  agreement  of the parties  with respect to the
subject matter hereof.

         14. Time of Essence. Time shall be of the essence in this Agreement.

         15. Escrow  Agent.  The Escrow Agent shall not be liable for any action
taken or  omitted  by it in good  faith  and its  liability  hereunder  shall be
limited to liability for gross negligence or willful misconduct on its part. The
Company  and the  Purchaser  agree to save  harmless,  indemnify  and defend the
Escrow Agent for, from and against any loss, damage,  liability,  judgment, cost
and expense  whatsoever,  by reason of, or on account of, any  misrepresentation
made to it or its status or  activities  as Escrow  Agent  under this  Agreement
except for any loss, damage, liability, judgment, cost or expense resulting from
gross negligence or willful misconduct on the part of the Escrow Agent.

         The Escrow Agent shall not be responsible  for any failure or inability
of any of the  parties  to  perform  or  comply  with  the  provisions  of  this
Agreement, or the agreements delivered in connection herewith.

         In the performance of its duties  hereunder,  the Escrow Agent shall be
entitled  to  rely  in  good  faith  upon  any  document  (including   facsimile
transmitted copies of documents), instrument or signature believed by it in good
faith to be  genuine  and to be  signed by any  party  hereto  or an  authorized
officer or agent thereof,  and shall not be required to investigate the truth or
accuracy of any  statement  contained in any such  document or  instrument.  The
Escrow  Agent may assume in good faith  that any person  purporting  to give any
notice in accordance  with the provisions  hereof has been duly authorized to do
so.

         Each party hereto  acknowledges that (a) the Escrow Agent is not acting
as legal counsel to such party in any manner or respect in  connection  with the
transactions contemplated by this Agreement, and (b) the Escrow Agent is serving
as an accommodation to the parties hereto. Each party further  acknowledges that

nature of conflict of interest  against the Escrow Agent and further agrees that
in the event of any dispute which arises hereunder, or otherwise between a party
and Meyers, the Escrow Agent shall be free to represent Meyers.

                                      -11-

be paid to and held by it hereunder;

         (b) promptly  notify the Purchaser  and the Company of any  discrepancy
between the amounts set forth on any statement delivered by the Purchaser and/or
the Company and the sum or sums delivered to it therewith;

         (c) be under no duty to accept funds, checks, drafts or instruments for
the payment of money from anyone other than the Company or the Purchaser,  or to
give any receipt therefor except to the Company or the Purchaser, with a copy in
each case to the Company;

         (d) be  protected  in acting  upon any  notice,  request,  certificate,
approval,  consent or other paper reasonably believed by it to be genuine and to
be signed by the proper party or parties (including,  but not limited to, copies
of documents transmitted by facsimile);

         (e) be permitted  to consult with counsel of its choice,  and shall not
be liable for any action taken,  suffered,  or omitted by it in accordance  with
the advice of such counsel;  provided,  however, that nothing in this subsection
(e), nor any action taken by the Escrow  Agent,  or suffered or omitted by it in
accordance  with the advice of any counsel,  shall relieve the Escrow Agent from
liability for any claims that are occasioned by its gross  negligence or willful
misconduct;

         (f)  not  be  bound  by  any  modification,   amendment,   termination,
cancellation,  or  recission  of this  Agreement,  unless  the same  shall be in
writing and signed by it;

         (g) be  entitled to refrain  from taking any action  other than to keep
all property held in escrow if it (i) shall be uncertain  concerning  its duties
or rights  hereunder,  or (ii) shall have  received  claims or demands  from any
party, or (iii) shall have received  instructions  from the Purchaser and/or the
Company which,  in the Escrow Agent's  opinion,  are in conflict with any of the
provisions of this Agreement, until it shall have received a final judgment by a
court of competent jurisdiction;

         (h)  have  no  liability  for  following  the  instructions  herein  or
expressly  provided  for  herein,  or  the  written  instructions  given  by the
Purchaser and/or the Company; and

         (i) have the right, at any time, to resign  hereunder by giving written
notice  of its  resignation  to all  other  parties  hereto  at least  three (3)
business days prior to the date  specified for such  resignation to take effect,
and upon the effective date of such  resignation all cash and other payments and
all other property then held by the Escrow Agent hereunder shall be delivered by
it to such person as may be designated in writing by the other parties executing

                                       -12-

<PAGE>

this Agreement,  whereupon the Escrow Agent's obligations  hereunder shall cease
and  terminate.  If no  such  person  has  been  designated  by such  date,  all
obligations  of the  Escrow  Agent  hereunder  shall,  nevertheless,  cease  and
terminate.  The Escrow Agent's sole  responsibility  thereafter shall be to keep
safely  all  property  then  held by it and to  deliver  the  same  to a  person
designated by the other parties  executing this Agreement or in accordance  with
the   directions  of  a  final  order  or  judgment  of  a  court  of  competent
jurisdiction.       

         16.  Right of  First  Refusal.  For a  period  of  twelve  (12)  months
following the Closing,  the  Purchaser  shall have a five (5) day right of first
refusal  (together  with any other  purchasers in this offering to the extent of
their  original  investment  in this  Note)  to  purchase  any  debt  or  equity
securities  of the  Company  which the  Company  proposes  to issue in a private
placement transaction (excluding sales to employees).

         17.  Shorting  Position.  The Purchaser has no existing  short position
with respect to the Common Stock and agrees not to enter into any short sales or
other hedging  transactions  with respect to the Common Stock at any time during
the first sixty (60) days after the closing of this Agreement. Purchaser further
agrees that, at all times after the execution of this Agreement by the Purchaser
and  prior to  conversion  of all  principal  amount of the  Notes  acquired  by
Purchaser,  it will  keep its  purchase  of the Note and  Warrant  confidential,
except as  required by law and except as  necessary  in the  ordinary  course of
Purchaser's business.

         18.  Delivery  of Stock.  The  Company  will  permit the  Purchaser  to
exercise its right to convert the Note and  exercise the Warrant by  telecopying
an executed and completed  Conversion Notice or Notice of Exercise,  as the case
may be, to the Company and delivering within three business days thereafter, the
original Conversion Notice and Note or Notice of Exercise and Warrant by express
courier.  Each  date on which a  Conversion  Notice or  Notice  of  Exercise  is
telecopied  to and  received by the Company in  accordance  with the  provisions
hereof  shall be  deemed a  conversion  date.  The  Company  will  transmit  the
certificates representing the Note Shares or Warrant Shares and the newly issued
Note representing the amount of the Note which remains unconverted, or the newly
issued Warrant  representing  that portion of the Warrant that is not exercised,
to the Purchaser via express courier within three business days after receipt by
the  Company  of the  original  Conversion  Notice and the Note or the Notice of
Exercise and the Warrant.

         19. Liquidated Damages for Failure to Deliver.  The Company understands
that a delay beyond the deadline for delivery,  specified in paragraph 18, could
result in economic loss to the Purchaser.  As  compensation to the Purchaser for
such loss, the Company agrees to pay late payments to the Purchaser for the late
issuance  of  shares  issuable  at  conversion  of the Note or  exercise  of the

                                      -13-

Warrant in accordance  with the  following  schedule  (where "No.  Business Days

receipt by the  Company of the  original  Conversion  Notice and the Note or the

                                           Day Late Beyond 10 Days

         The Company  shall make any  payments  incurred  under this  Section in
immediately   available  funds  upon  demand.   Nothing  herein  shall  limit  a
Purchaser's  right to pursue actual  damages for the Company's  failure to issue
and deliver  Note Shares or Warrant  Shares to the  Purchaser.  Furthermore,  in
addition to any other remedy which may be  available  to the  Purchaser,  in the
event that the Company fails for any reason to effect delivery of Note Shares or
Warrant  Shares within five business days after the Delivery Date, the Purchaser
will be entitled to revoke the relevant  Conversion Notice or Notice of Exercise
by  delivering a notice to such effect to the Company  whereupon the Company and
the Purchaser shall each be restored to their respective  positions  immediately
prior to such Conversion Notice or Notice of Exercise.

         20.  Non-delivery of the Note Shares or Warrant Shares.  If, within ten
(10)  business  days of the date after  receipt by the  Company of the  original
Conversion  Notice  and the  original  Note or the  Notice of  Exercise  and the

                                      -14-

<PAGE>

Warrant, as the case may be, the Company shall fail to (i) issue the Note Shares
or Warrant Shares,  and (ii) deliver to the Purchaser the Note Shares or Warrant
Shares,  for any reason other than  failure by the  Purchaser to comply with its
obligations hereunder, then the Company shall:

              (a) hold the Purchaser  harmless against any loss, claim or damage
arising from or as a result of such failure by the Company  (including,  without
limitation,  any such loss,  claim or damage  resulting  from an  obligation  to
resell the Note Shares or Warrant Shares); and

              (b) reimburse the Purchaser for all of its out-of-pocket  expenses
reasonably incurred,  including fees and disbursements of its counsel,  incurred
by the  Purchaser  in  connection  with  this  Agreement  and  the  transactions
contemplated  herein;  provided  however,  that the  Company  shall then have no
further liability to the Purchaser except as provided for in this Section 20.

              IN WITNESS  WHEREOF,  this  Agreement  has been duly  executed and
delivered by the duly authorized  officer(s) of each party hereto as of the date
first above written.

         B.  To  induce  the  Initial  Investors  to  execute  and  deliver  the
Securities  Purchase  Agreement,  the  Company  has  agreed to  provide  certain
registration rights under the Securities Act of 1933, as amended,  and the rules
and regulations thereunder, or any similar successor statute (collectively,  the
"1933 Act"), and applicable state securities laws;

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants  contained  herein  and other  good and  valuable  consideration,  the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and the
Initial Investors hereby agree as follows:

         1. DEFINITIONS.

              (a) As used in this Agreement,  the following terms shall have the
following meanings:

                  (i)   "Investors"   means  the  Initial   Investors   and  any
transferees  or assignees  who agrees to become bound by the  provisions of this
Agreement in accordance with Section 9 hereof.

                  (ii) "register,"  "registered," and "registration"  refer to a
registration  effected  by  preparing  and filing a  Registration  Statement  or
Statements  in  compliance  with the 1933 Act and pursuant to Rule 415 under the
1933 Act or any successor rule providing for offering securities on a continuous
basis ("Rule 415"),  and the  declaration or ordering of  effectiveness  of such
Registration  Statement by the United States Securities and Exchange  Commission
(the "SEC").

                  (iii) "Registrable  Securities" means the Securities issued or
issuable upon  conversion of the Note or exercise of the Warrant,  any shares of
capital  stock  issued  or  issuable  as a  dividend  on or in  exchange  for or
otherwise with respect to any of such Securities.

                  (iv)  "Registration Statement" means a registration statement 
of the Company under the 1933 Act.

              (b) Capitalized terms used herein and not otherwise defined herein
shall  have  the  respective  meanings  set  forth  in the  Securities  Purchase
Agreement.

         2. REGISTRATION.

              (a)  Mandatory  Registration.  The Company  shall  within ten (10)
after the Closing Date under the  Securities  Purchase  Agreement  (the "Closing
Date") file with the SEC a  Registration  Statement on Form S-3 (or, if Form S-3
is not  then  available,  on such  form  of  Registration  Statement  as is then
available to effect a registration of the Registrable Securities, subject to the
consent of the Initial Investors (as determined  pursuant to Section l0 hereof),
which  consent  will not be  unreasonably  withheld)  covering the resale of the
Registrable  Securities,  which Registration  Statement, to the extent allowable
under the 1933 Act and the Rules  promulgated  thereunder  (including Rule 416),
shall state that such  Registration  Statement  also  covers such  indeterminate
number  of  additional  shares  of  Common  Stock as may  become  issuable  upon
conversion of the Notes and the exercise of the Warrants (i) to prevent dilution
resulting from stock splits,  stock dividends or similar transactions or (ii) by
reason of changes in the number of Securities issued or issuable upon conversion
of the Notes in  accordance  with the terms of the Notes  and/or  changes in the
number of  Securities  issued or issuable  upon  exercise of the  Warrants.  The
Company  shall use its best  efforts  to cause such  registration  to become and
remain effective  (including the taking of such steps as are necessary to obtain
the removal of any stop orders);  provided, that the Investors shall furnish the
Company with such appropriate information in connection therewith as the Company
shall  reasonably  request in  writing.  The  Registration  Statement  (and each
amendment  or  supplement   thereto,   and  each  request  for  acceleration  of
effectiveness thereof) shall be provided to (and subject to the approval of) the
Initial Investors and its counsel prior to its filing or other submission.

              (b) Liquidated Damages.  The Company shall use its best efforts to
obtain  effectiveness of the Registration  Statement as soon as practicable.  If
(i) the

                                       -2-



<PAGE>



Registration  Statement(s)  covering the Registrable  Securities  required to be
filed by the Company  pursuant to Section 2(a) hereof is not declared  effective
by the SEC  within  sixty (60) days  after the  Closing  Date of the sale of the
Notes and the  Warrants  (other than by reason of any act or failure to act in a
timely  manner  by the  Investors  or  Investors'  counsel),  or if,  after  the
Registration  Statement has been declared  effective by the SEC, sales cannot be
made pursuant to the  Registration  Statement  (by reason of stop order,  or the
Company's  failure to update  the  Registration  Statement),  or (ii) the Common
Stock is not listed or included  for  quotation  on the NASDAQ  National  Market
System (the  "NASDAQ-NMS"),  NASDAQ Small Cap, the New York Stock  Exchange (the
"NYSE") or the American Stock Exchange (the "AMEX"),  then the Company will make
payments  to the  Investors  in such  amounts  and at such  times  as  shall  be
determined  pursuant to this Section  2(b) as partial  relief for the damages to
the  Investors by reason of any such delay in or  reduction of their  ability to
sell the  Registrable  Securities  (which  remedy  shall not be exclusive of any
other  remedies  available at law or in equity).  The Company  shall pay to each
holder of  Registrable  Securities  an amount equal to the  aggregate  "Purchase
Price"  (as  defined  below) of the  Notes  held by such  Investors  (including,
without limitation,  Notes that have been converted into Securities then held by
such  Investors) (the  "Aggregate  Share Price")  multiplied by two and one-half
hundredths  (.025)  times the sum of:  (i) the  number of months  (prorated  for
partial  months)  after the end of such 60-day  period and prior to the date the
Registration Statement is declared effective by the SEC, provided, however, that
there  shall  be  excluded   from  such  period  any  delays  which  are  solely
attributable to changes required by the Investors in the Registration  Statement
with  respect to  information  relating  to the  Investors,  including,  without
limitation,  changes  to the  plan of  distribution,  or to the  failure  of the
Investors to conduct  their  review of the  registration  statement  pursuant to
Section  2(a) above in a  reasonably  prompt  manner;  (ii) the number of months
(prorated  for  partial  months)  that  sales  cannot  be made  pursuant  to the
Registration  Statement  after  the  Registration  Statement  has been  declared
effective; and (iii) the number of months (prorated for partial months) that the
Common Stock is not listed or included for quotation on the  NASDAQ-NMS,  NASDAQ
Small  Cap,  NYSE or AMEX after the  Registration  Statement  has been  declared
effective. (For example, if the Registration Statement becomes effective one (1)
month after the end of such  60-day  period,  the Company  would pay $25,000 for
each  $1,000,000 of Aggregate  Share Price and would continue to pay $25,000 for
each  $1,000,000  of  Aggregate  Share  Price until the  Registration  Statement
becomes  effective.)  Such amounts shall be paid in cash or, at each  Investor's
option (but  subject to the  limitations  contained in Section 3.1 of the Note),
may be convertible  into Common Stock at the  "Conversion  Price" (as defined in
the Note).  Any shares of Common  Stock issued upon  conversion  of such amounts
shall be Registrable  Securities.  If the Company desires to convert the amounts
due  hereunder  into  Registrable  Securities it shall so notify the Investor in
writing  within  three (3)  business  days of the date on which such amounts are
first payable in cash and such amounts shall be so convertible  (pursuant to the
mechanics set forth in the Note),  beginning on the last day upon which the cash
amount  would  otherwise  be due in  accordance  with  the  following  sentence.
Payments of cash  pursuant  hereto  shall be made within ten (10) days after the
end of each period that gives rise to such obligation,

                                       -3-



<PAGE>



provided  that,  if any such  period  extends  for more than  thirty  (30) days,
interim  payments  shall be-made for each such thirty (30) day period.  The term
"Purchase  Price" means the purchase  price paid by the  Investors for the Note.
Upon agreement of both the Purchaser and the Company, any liquidated damages due
under the provisions of this subparagraph may be paid in shares of Common Stock,
registered  as if such stock  were Note  Shares,  and  valued at the  Conversion
Price, as such term is defined in Section 3.1 of the Note.

              (c)  Piggy-Back  Registrations.  If  at  any  time  prior  to  the
expiration of the Registration Period (as hereinafter defined) the Company shall
file with the SEC a Registration  Statement  relating to (i) a firm underwritten
offering  for its own account or the account of others under the 1933 Act of any
of its equity  securities or (ii) any other  offering for its own account or the
account of others under the 1933 Act of any of its equity securities (other than
on Form S-4 or Form S-8 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) at a time when the Registration Statement contemplated by Section
l(a) hereof is not  effective,  the Company  shall send to each  Investor who is
entitled to  registration  rights under this Section 2(c) written notice of such
determination  and, if within fifteen (15) days after the effective date of such
notice, such Investor shall so request in writing,  the Company shall include in
such Registration  Statement all or any part of the Registrable  Securities such
Investor  requests  to be  registered,  except that if, in  connection  with any
underwritten  public  offering  for the  account  of the  Company  the  managing
underwriter(s)  thereof  shall  impose a  limitation  on the number of shares of
Common Stock that may be included in the Registration Statement because, in such
underwriter(s)' judgment,  marketing or other factors dictate such limitation is
necessary to facilitate public distribution, then the Company shall be obligated
to include  in such  Registration  Statement  only such  limited  portion of the
Registrable  Securities  with  respect  to which  such  Investor  has  requested
inclusion   hereunder  as  the  underwriter  shall  permit.   Any  exclusion  of
Registrable  Securities  shall be made pro rata among the  Investors  seeking to
include  Registrable  Securities,  in  proportion  to the number of  Registrable
Securities sought to be included by such Investors;  provided, however, that the
Company  shall not exclude  any  Registrable  Securities  unless the Company has
first excluded all outstanding securities, the holders of which are not entitled
to  inclusion  of such  securities  in such  Registration  Statement  or are not
entitled to pro rata inclusion with the  Registrable  Securities;  and provided,
further,  however,  that,  after  giving  effect  to the  immediately  preceding
proviso,  any exclusion of  Registrable  Securities  shall be made pro rata with
holders of other  securities  having the right to include such securities in the
Registration Statement other than holders of securities entitled to inclusion of
their securities in such Registration Statement by reason of demand registration
rights.  No right to registration of Registrable  Securities  under this Section
2(c) shall be construed to limit any  registration  required  under Section 2(a)
hereof.  If an  offering  in  connection  with which an  Investor is entitled to
registration  under this Section  2(c) is an  underwritten  offering,  then each
Investor  whose  Registrable   Securities  are  included  in  such  Registration
Statement shall, unless otherwise agreed by the Company, offer and

                                       -4-



<PAGE>



sell such  Registrable  Securities in an  underwritten  offering  using the same
underwriter or underwriters and, subject to the provisions of this Agreement, on
the same terms and  conditions as other shares of Common Stock  included in such
underwritten offering.

              (d) Eligibility for Form S-3. The Company  represents and warrants
that it meets the  requirements  for the use of Form S-3 for registration of the
sale  by the  Initial  Investors  and  any  other  Investor  of the  Registrable
Securities  and the Company  shall file all reports  required to be filed by the
Company with the SEC in a timely manner so as to maintain such  eligibility  for
the use of Form S-3.

         3.  OBLIGATIONS OF THE COMPANY.

         In connection with the registration of the Registrable Securities,  the
Company shall have the following obligations:

              (a) The Company  shall within ten (10) days after the Closing Date
prepare and file promptly with SEC, a Registration Statement with respect to the
number of  Registrable  Securities  provided in Section 2(a), and thereafter use
its best efforts to cause such  Registration  Statement  relating to Registrable
Securities to become  effective as soon as possible after such filing,  and keep
the  Registration  Statement  effective  pursuant to Rule 415 at all times until
such  date as is the  earlier  of (i) the date on which  all of the  Registrable
Securities have been sold by the Investors and (ii) the date on which all of the
Registrable  Securities  that had not been sold by the Investors (in the opinion
of  counsel  to  the  Initial   Investors)  may  be  immediately   sold  without
registration  (the  "Registration   Period"),   which   Registration   Statement
(including  any  amendments or supplements  thereto and  prospectuses  contained
therein and all documents  incorporated by reference  therein) shall not contain
any  untrue  statement  of a  material  fact or omit to  state a  material  fact
required to be stated therein,  or necessary to make the statements  therein not
misleading.  The Company  shall  furnish to the  Investor  copies of  reasonably
complete drafts of all such documents proposed to be filed (including  exhibits,
if any), and any such Investor shall have the opportunity to object,  within two
(2) business days, to any information pertaining solely to such Investor that is
contained therein and the company will make the corrections reasonably requested
by such  Investor  with  respect  to such  information  prior to filing any such
Registration Statement or amendment.

              (b)  The  Company  shall  prepare  and  file  with  the  SEC  such
amendments  (including   post-effective   amendments)  and  supplements  to  the
Registration   Statement  and  the  prospectus   used  in  connection  with  the
Registration  Statement as may be necessary to keep the  Registration  Statement
effective at all times during the Registration  Period, and, during such period,
comply with the  provisions of the 1933 Act with respect to the  disposition  of
all Registrable  Securities of the Company covered by the Registration Statement
until such time as all of such  Registrable  Securities have been disposed of in
accordance  with the intended  methods of  disposition  by the seller or sellers
thereof as set forth in the Registration  Statement.  In the event the number of
shares available under a Registration Statement filed pursuant to this Agreement
is insufficient to cover all of the

                                       -5-



<PAGE>



Registrable  Securities  issued or issuable  upon - conversion  of the Notes and
exercise of the Warrants, the Company shall amend the Registration Statement, or
file a new  Registration  Statement (on the short form available  therefore,  if
applicable),  or both, so as to cover all of the Registrable Securities, in each
case, as soon as practicable, but in any event within thirty (30) days after the
necessity  therefor  arises  (based on the market  price of the Common Stock and
other  relevant  factors on which the Company  reasonably  elects to rely).  The
Company  shall  use  its  best  efforts  to  cause  such  amendment  and/or  new
Registration  Statement to become effective as soon as practicable following the
filing thereof.

              (c) The Company shall furnish to each Investor  whose  Registrable
Securities are included in the Registration  Statement and its legal counsel (i)
promptly  after the same is prepared  and publicly  distributed,  filed with the
SEC, or received by the Company, one copy of the Registration  Statement and any
amendment thereto, each preliminary prospectus and prospectus and each amendment
or supplement thereto,  and, in the case of the Registration  Statement referred
to in Section  2(a),  each letter  written by or on behalf of the Company to the
SEC or the staff of the SEC, and each material item of  correspondence  from the
SEC or the  staff  of the  SEC,  in each  case  relating  to  such  Registration
Statement  (other than any portion thereof which contains  information for which
the Company has sought confidential  treatment),  and (ii) such number of copies
of a prospectus,  including a preliminary  prospectus,  and all  amendments  and
supplements  thereto and such other  documents as such  Investor may  reasonably
request in order to facilitate  the  disposition of the  Registrable  Securities
owned by such Investor.

              (d) The Company  shall use its best  efforts to (i)  register  and
qualify the Registrable  Securities covered by the Registration  Statement under
such other  securities  or "blue sky" laws of such  jurisdictions  in the United
States as the  Investors  who hold a majority  in  interest  of the  Registrable
Securities  being  offered  reasonably  request,  (ii) prepare and file in those
jurisdictions  such  amendments   (including   post-effective   amendments)  and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in such jurisdictions;  provided,  however, that
the  Company  shall not be required in  connection  therewith  or as a condition
thereto to (a)  qualify to do business  in any  jurisdiction  where it would not
otherwise be required to qualify but for this Section 3(d),  (b) subject  itself
to general  taxation  in any such  jurisdiction,  (c) file a general  consent to
service of process in any such  jurisdiction,  (d) provide any undertakings that
cause the Company undue expense or burden, or (e) make any change in its charter
or bylaws,  which in each case the Board of Directors of the Company  determines
to be contrary to the best interests of the Company and its stockholders.

              (e) As promptly as practicable after becoming aware of such event,
the Company shall notify each  Investor of the happening of any event,  of which
the

                                       -6-



<PAGE>



Company  has  knowledge,  as a result of which the  prospectus  included  in the
Registration  Statement,  as then in effect,  includes an untrue  statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the  statements  therein not  misleading,  and use its best
efforts  promptly  to prepare a  supplement  or  amendment  to the  Registration
Statement to correct such untrue statement or omission,  and deliver such number
of copies of such  supplement or amendment to each Investor as such Investor may
reasonably request.

              (f) The Company shall use its best efforts to prevent the issuance
of any  stop  order or  other  suspension  of  effectiveness  of a  Registration
Statement,  and, if such an order is issued,  to obtain the  withdrawal  of such
order at the  earliest  possible  moment and to notify each  Investor  who holds
Registrable Securities being sold (or, in the event of an underwritten offering,
the  managing  underwriters)  of the  issuance of such order and the  resolution
thereof.

              (g) The Company  shall permit a single firm of counsel  designated
by the Initial Investors to review the Registration Statement and all amendments
and supplements  thereto a reasonable  period of time prior to their filing with
the SEC, and not file any  document in a form to which such  counsel  reasonably
objects.  Any period of review shall be added to the time in which  registration
is required to be filed and effective, as appropriate.  The cost and expenses of
such counsel shall be borne exclusively by the Initial Investors.

              (h) The Company  shall make  generally  available  to its security
holders  as soon as  practical,  but not later than  ninety  (90) days after the
close of the period covered  thereby,  an earnings  statement (in form complying
with the  provisions  of Rule 158 under the 1933 Act)  covering  a  twelve-month
period  beginning not later than the first day of the Company's  fiscal  quarter
next following the effective date of the Registration Statement.

              (i)  The  Company  shall  hold in  confidence  and  not  make  any
disclosure of information  concerning an Investor provided to the Company unless
(i) disclosure of such  information is necessary to comply with federal or state
securities  laws, (ii) the disclosure of such  information is necessary to avoid
or correct a misstatement or omission in any Registration  Statement,  (iii) the
release of such  information  is ordered  pursuant  to a subpoena or other order
from a court  or  governmental  body of  competent  jurisdiction,  or (iv)  such
information  has been made  generally  available  to the  public  other  than by
disclosure in violation of this or any other agreement.  The Company agrees that
it shall,  upon  learning  that  disclosure  of such  information  concerning an
Investor  is  sought  in  or  by a  court  or  governmental  body  of  competent
jurisdiction  or through other means,  give prompt notice to such Investor prior
to making such disclosure,  and allow the Investor, at its expense, to undertake
appropriate  action to- prevent  disclosure of, or to obtain a protective  order
for, such information.


                                       -7-



<PAGE>



              (j) The Company shall use its best efforts either to (i) cause all
the Registrable Securities covered by the Registration Statement to be listed on
the  NYSE or the  AMEX  or  another  national  securities  exchange  and on each
additional national securities exchange on which securities of the same class or
series  issued by the  Company are then  listed,  if any, if the listing of such
Registrable  Securities is then permitted  under the rules of such exchange,  or
(ii) secure the  designation and quotation,  of all the  Registrable  Securities
covered by the Registration Statement on the NASDAQ- NMS or, if not eligible for
the NASDAQ-NMS on the NASDAQ Small Cap.

              (k) The  Company  shall  provide a transfer  agent and  registrar,
which may be a single entity, for the Registrable  Securities not later than the
effective date of the Registration Statement.

              (l) The  Company  shall  cooperate  with  the  Investors  who hold
Registrable   Securities   being  offered  and  the  managing   underwriter   or
underwriters,  if any, to  facilitate  the timely  preparation  and  delivery of
certificates  (not bearing any  restrictive  legends)  representing  Registrable
Securities to be offered pursuant to the Registration  Statement and enable such
certificates to be in such denominations or amounts,  as the case may be, as the
managing  underwriter or  underwriters,  if any, or the Investors may reasonably
request   and-registered   in  such  names  as  the  managing   underwriter   or
underwriters, if any, or the Investors may request.

              (m)  The  Company   shall  use  its  best  efforts  to  cause  all
Registrable  Securities covered by such registration  statement to be registered
with or approved by such other  governmental  agencies or  authorities as may be
necessary to enable each holder thereof to consummate disposition of Registrable
Securities.

         4.  OBLIGATIONS OF THE INVESTORS.

         In connection with the registration of the Registrable Securities,  the
Investors shall have the following obligations:

              (a) It shall be a condition  precedent to the  obligations  of the
Company to complete the registration  pursuant to this Agreement with respect to
the  Registrable  Securities of a particular  Investor that such Investor  shall
furnish to the  Company  such  information  regarding  itself,  the  Registrable
Securities  held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the registration
of such  Registrable  Securities  and shall execute such documents in connection
with such registration as the Company may reasonably request.

              (b)  Each  Investor,   by  such   Investor's   acceptance  of  the
Registrable  Securities,  agrees to  cooperate  with the  Company as  reasonably
requested by the Company in connection  with the  preparation  and filing of the
Registration Statement hereunder,  unless such Investor has notified the Company
in writing of such Investor's

                                       -8-



<PAGE>



election  to exclude  all of such  Investor's  Registrable  Securities  from the
Registration Statement.

              (c) Each Investor agrees that, upon receipt of any notice from the
Company of the  happening of any event of the kind  described in Section 3(e) or
3(f),  such Investor will  immediately  discontinue  disposition  of Registrable
Securities  pursuant to the  Registration  Statement  covering such  Registrable
Securities  until such Investor's  receipt of the copies of the  supplemented or
amended  prospectus  contemplated by Section 3(e) or 3(f) and, if so directed by
the Company,  such Investor  shall deliver to the Company (at the expense of the
Company) or destroy (and deliver to the Company a  certificate  of  destruction)
all  copies in such  Investor's  possession,  of the  prospectus  covering  such
Registrable Securities current at the time of receipt of such notice.

              (d) No Investor may participate in any  underwritten  registration
hereunder  unless such Investor (i) agrees to sell such  Investor's  Registrable
Securities on the basis provided in any  underwriting  arrangements in usual and
customary  form  entered into by the Company,  (ii)  completes  and executes all
questionnaires,  powers of attorney,  indemnities,  underwriting  agreements and
other  documents  reasonably  required  under  the  terms  of such  underwriting
arrangements,  and (iii)  agrees to pay its pro rata  share of all  underwriting
discounts  and  commissions  and any expenses in excess of those  payable by the
Company pursuant to Section 5 below.

         5.   EXPENSES OF REGISTRATION.

         All  reasonable  expenses,   other  than  underwriting   discounts  and
commissions,   incurred   in   connection   with   registrations,   filings   or
qualifications pursuant to Sections 2 and 3, including,  without limitation, all
registration,  listing and qualifications fees, printers and accounting fees and
the fees and disbursements of counsel for the Company shall be borne exclusively
by the Company.

         6.  INDEMNIFICATION.

         In the event any Registrable  Securities are included in a Registration
Statement under this Agreement:

              (a) To the extent  permitted by law,  the Company will  indemnify,
hold  harmless  and  defend  (i)  each  Investor  who  holds  such   Registrable
Securities, and (ii) the directors,  officers,  partners,  employees, agents and
each person who control any  Investor  within the meaning of the 1933 Act or the
Securities  Exchange Act of 1934, as amended (the "1934 Act"), if any, (each, an
"Indemnified  Person"),  against any joint or several losses,  claims,  damages,
liabilities  or expenses  (collectively,  together with actions,  proceedings or
inquiries by any regulatory or self-regulatory  organization,  whether commenced
or  threatened,  in respect  thereof,  "Claims") to which any of them may become
subject  insofar as such Claims  arise out of or are based upon:  (i) any untrue
statement  or alleged  untrue  statement  of a material  fact in a  Registration
Statement or the

                                       -9-



<PAGE>



omission or alleged  omission to state  therein a material  fact  required to be
stated or  necessary to make the  statements  therein not  misleading,  (ii) any
untrue statement or alleged untrue statement of a material fact contained in any
preliminary  prospectus if used prior to the effective date of such Registration
Statement, or contained in the final prospectus (as amended or supplemented,  if
the Company files any amendment  thereof or supplement  thereto with the SEC) or
the omission or alleged omission to state therein any material fact necessary to
make the statements made therein,  in light of the circumstances under which the
statements therein were made, not misleading,  or (iii) any violation or alleged
violation  by the  Company  of the  1933  Act,  the 1934  Act,  any  other  law,
including,  without  limitation,  any  state  securities  law,  or any  rule  or
regulation  thereunder  relating  to  the  offer  or  sale  of  the  Registrable
Securities  (the  matters in the  foregoing  clauses  (i) through  (iii)  being,
collectively,  "Violations").  Subject to the  restrictions set forth in Section
6(c) with respect to the number of legal  counsel,  the Company shall  reimburse
the Investors and each such underwriter or controlling person,  promptly as such
expenses are incurred and are due and payable,  for any reasonable legal fees or
other reasonable  expenses incurred by them in connection with  investigating or
defending  any such Claim.  Notwithstanding  anything to the contrary  contained
herein, the indemnification  agreement contained in this Section 6(a): (i) shall
not apply to a Claim  arising out of or based upon a Violation  which  occurs in
reliance upon and in  conformity  with  information  furnished in writing to the
Company by any  Indemnified  Person  expressly  for use in  connection  with the
preparation  of the  Registration  Statement  or any such  amendment  thereof or
supplement  thereto;  (ii) shall not apply to amounts paid in  settlement of any
Claim if such  settlement is effected  without the prior written  consent of the
Company,  which  consent  shall not be  unreasonably  withheld;  and (iii)  with
respect to any  preliminary  prospectus,  shall not inure to the  benefit of any
Indemnified  Person  if the  untrue  statement  or  omission  of  material  fact
contained in the  preliminary  prospectus was corrected on a timely basis in the
prospectus,  as then amended or supplemented,  if such corrected  prospectus was
timely made  available by the Company  pursuant to Section 3(c) hereof,  and the
Indemnified  Person was  promptly  advised in writing  not to use the  incorrect
prospectus  prior to the use giving  rise to a  Violation  and such  Indemnified
Person,  notwithstanding  such advice,  used it. Such indemnity  shall remain in
full force and effect  regardless of any  investigation  made by or on behalf of
the  Indemnified  Person  and shall  survive  the  transfer  of the  Registrable
Securities by the Investors pursuant to Section 9.

              (b) In  connection  with any  Registration  Statement  in which an
Investor is  participating,  each such Investor agrees severally and not jointly
to  indemnify,  hold  harmless  and  defend,  to the same extent and in the same
manner set forth in Section 6(a), the Company,  each of its  directors,  each of
its  officers who signs the  Registration  Statement,  each person,  if any, who
controls the Company within the meaning of the 1933 Act or the 1934 Act, and any
other stockholder selling securities  pursuant to the Registration  Statement or
any of its directors or officers or any person who controls such  stockholder or
underwriter within the meaning of the 1933 Act or the 1934 Act (collectively and
together with an Indemnified Person, an "Indemnified Party"),  against any Claim
to which any of them may become subject, under the 1933 Act, the 1934 Act

                                      -10-

or  otherwise,  insofar  as  such  Claim  arises  out of or is  based  upon  any
Violation,  in each  case to the  extent  (and  only to the  extent)  that  such
Violation  occurs in reliance  upon and in conformity  with written  information
furnished to the Company by such Investor  expressly for use in connection  with
such  Registration  Statement;   and  subject  to  Section  6(c)  such  Investor
will-reimburse  any  legal or other  expenses  (promptly  as such  expenses  are
incurred and are due and payable) reasonably incurred by them in connection with
investigating or defending any such Claim; provided, however, that the indemnity
agreement  contained  in this  Section  6(b) shall not apply to amounts  paid in
settlement of any Claim if such settlement is effected without the prior written
consent of such  Investor,  which  consent shall not be  unreasonably  withheld;
provided,  further,  however,  that the  Investor  shall be  liable  under  this
Agreement  (including  this  Section 6(b) and Section 7) for only that amount as
does not exceed the net  proceeds  to such  Investor  as a result of the sale of
Registrable Securities pursuant to such Registration  Statement.  Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on  behalf of such  Indemnified  Party and shall  survive  the  transfer  of the
Registrable  Securities by the Investors pursuant to Section 9.  Notwithstanding
anything  to  the  contrary  contained  herein,  the  indemnification  agreement
contained in this Section 6(b) with respect to any preliminary  prospectus shall
not inure to the benefit of any  Indemnified  Party if the untrue  statement  or
omission of material fact contained in the preliminary  prospectus was corrected
on a timely basis in the prospectus, as then amended or supplemented.

              (c) Promptly after receipt by an Indemnified Person or Indemnified
Party  under  this  Section  6 of  notice  of the  commencement  of  any  action
(including any  governmental  action),  such  Indemnified  Person or Indemnified
Party shall, if a Claim in respect  thereof is to made against any  indemnifying
party under this Section 6, deliver to the  indemnifying  party a written notice
of the commencement  thereof, and the indemnifying party shall have the right to
participate in, and, to the extent the  indemnifying  party so desires,  jointly
with any other indemnifying  party similarly  noticed,  to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party and
the Indemnified  Person or the Indemnified  Party, as the case may be; provided,
however, that an Indemnified Person or Indemnified Party shall have the right to
retain its own counsel with the fees and expenses to be paid by the indemnifying
party,  if, in the reasonable  opinion of counsel  retained by the  indemnifying
party,  the  representation  by  such  counsel  of  the  Indemnified  Person  or
Indemnified  Party and the  indemnifying  party  would be  inappropriate  due to
actual or  potential  differing  interests  between such  Indemnified  Person or
Indemnified  Party and any  other  party  represented  by such  counsel  in such
proceeding. The indemnifying party shall pay for only one separate legal counsel
for the Indemnified Persons or the Indemnified Parties, as applicable,  and such
legal counsel shall be selected by Investors holding a  majority-in-interest  of
the Registrable  Securities included in the Registration  Statement to which the
Claim relates (with the approval of the Initial Investor if it holds Registrable
Securities  included  in such  Registration  Statement),  if the  Investors  are
entitled  to  indemnification  hereunder,  or the  Company,  if the  Company  is
entitled to  indemnification  hereunder,  as applicable.  The failure to deliver
written notice to the indemnifying party within a

                                      -11-



<PAGE>



reasonable  time of the  commencement  of any such action shall not relieve such
indemnifying  party of any liability to the  Indemnified  Person or  Indemnified
Party under this Section 6, except to the extent that the indemnifying  party is
actually  prejudiced in its ability to defend such action.  The  indemnification
required  by this  Section 6 shall be made by  periodic  payments  of the amount
thereof  during the course of the  investigation  or defense,  as such  expense,
loss, damage or liability is incurred and is due and payable.

         7.  CONTRIBUTION.

         To  the  extent  any   indemnification  by  an  indemnifying  party  is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided,  however, that
(i) no contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section  6, (ii) no  seller  of  Registrable  Securities  guilty  of  fraudulent
misrepresentation  (within  the meaning of Section 1 l(f) of the 1933 Act) shall
be entitled to  contribution  from any seller of Registrable  Securities who was
not  guilty  of  such  fraudulent  misrepresentation,   and  (iii)  contribution
(together with any indemnification or other obligations under this Agreement) by
any  seller of  Registrable  Securities  shall be  limited  in amount to the net
amount of proceeds  received  by such  seller from the sale of such  Registrable
Securities.

         8.  REPORTS UNDER THE 1934 ACT.

         With a view to making  available to the  Investors the benefits of Rule
144  promulgated  under the 1933 Act or any other  similar rule or regulation of
the SEC that may at any time  permit the  Investors  to sell  securities  of the
Company to the public without registration ("Rule 144"), the Company agrees to:

              (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

              (b) file with the SEC in a timely  manner  all  reports  and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such  requirements and the filing of such reports
and other documents is required for the applicable provisions of Rule 144; and

              (c)  furnish  to each  Investor  so long  as  such  Investor  owns
Registrable  Securities,  promptly upon request,  (i) a written statement by the
Company that it has complied  with the reporting  requirements  of Rule 144, the
1933 Act and the 1934 Act,  (ii) a copy of the most recent  annual or  quarterly
report of the  Company  and such other  reports  and  documents  so filed by the
Company,  and (iii) such other  information  as may be  reasonably  requested to
permit  the  Investors  to sell such  securities  pursuant  to Rule 144  without
registration.

restricted  under the 1933 Act and applicable  state securities laws, (iv) at or
before the time the Company  receives the written notice  contemplated by clause
(ii) of this  sentence,  the  transferee or assignee  agrees in writing with the

         SECTION 2.1 Exchange and  Registration of Transfer of Notes. The Holder
may, at its option,  surrender this Note at the office of the Issuer and receive

provisions of this Section 2.2 are exclusive with respect to the  replacement of

rights and  remedies  notwithstanding  any law or statute  existing or hereafter
enacted  to  the  contrary  with  respect  to  the   replacement  of  negotiable
instruments or other securities without their surrender.

         SECTION 2.3 Who Deemed Absolute  Owner.  The Issuer may deem the person
in whose  name this Note  shall be  registered  upon the  registry  books of the
Issuer to be, and may treat it as, the absolute  owner of this Note  (whether or

                               CONVERSION OF NOTE

         SECTION 3.1 Conversion:  Conversion Price. At the option of the Holder,
at any time from the sixtieth  (60th) day following the date of issuance of this
Note  until  this Note is paid in full,  this Note may be  converted,  either in
whole or in part up to the  principal  amount hereof (or in case some portion of
this Note shall have been called for redemption  prior to such date, then at the
portion that is not so called), at the conversion price the ("Conversion Price")
equal to seventy percent (70%) (the  "Conversion  Ratio") of the average closing
bid price of the Common Stock on the five Trading Days immediately preceding the
relevant Conversion Date (the "Valuation  Period"),  (but in no event shall such
amount be (a) in excess of 70% of the  average  closing  bid price of the Common
Stock on the five Trading Days  immediately  preceding the issuance date of this
Note), plus 400 shares of Common Stock for each $10,000 principal amount of this
Note converted. Notwithstanding anything to the contrary contained herein, in no
event  shall the Holder be  entitled  to convert  this Note into any Note Shares
when the result of such  conversion  would  entitle  the Holder to receive  that
number  of  shares  of the  Issuer's  Common  Stock of which the sum of (xx) the
number of  shares  of Common  Stock  beneficially  owned by the  Holder  and its
affiliates  (other than shares of Common Stock which may be deemed  beneficially
owned  through the ownership of the  unconverted  portion of this Note) and (yy)
the number of shares of Common  Stock  issuable  upon  conversion  of this Note,
would result in  beneficial  ownership by the Holder and its  affiliates of more
than 4.9% of the  outstanding  shares of Common Stock.  For the purposes of this
provision,  beneficial  ownership shall be determined in accordance with Section
13(d) of the  Securities  Exchange Act of 1934, as amended,  and Regulation 13 D
and G thereunder, except as otherwise provided in clause (xx) of this provision.

         SECTION 3.2 Exercise of Conversion Privilege.  In order to exercise the
conversion  privilege,  either in whole or in part,  the Holder shall  surrender
this Note to the Issuer during usual business hours at its principal  office and
shall give written  notice to the Issuer in the form attached  hereto in Annex I
(the "Conversion  Notice") at said office that the Holder elects to convert this
Note.  The Holder may exercise its right to convert this Note by  telecopying an
executed and completed  Conversion Notice. The Issuer shall convert the Note and
issue the Note Shares  effective  as of the time  requested by the Holder in the
Conversion Notice so long as such time is after the date on which the Conversion
Notice is given. The Conversion  Notice shall also state the name or names (with
address)  of the  persons  who are to become the  holders of the Note  Shares in
connection with such conversion.  Upon surrender for conversion, this Note shall
be  accompanied  by a proper  assignment  hereof to the  Issuer or in blank.  As
promptly as practicable after the receipt of the original  Conversion Notice and
this Note as  aforesaid,  but in any event no more than three (3) Business  Days
after the Issuer's  receipt of such Conversion  Notice and this Note, the Issuer
shall (i) issue the Note Shares issuable upon such conversion in accordance with
the  provisions  of this  Article  3,  and  (ii)  deliver  to the  Holder  (X) a
certificate or  certificate(s)  representing  the number of Note Shares to which
the Holder is entitled by virtue of such  conversion,  and (Y) cash, as provided
in Section  3.3, in respect of any fraction of a Note Share  issuable  upon such
conversion. Such conversion shall be deemed to have been effected at the time at
which the  Conversion  Notice  indicates  so long as this Note  shall  have been
surrendered as aforesaid at such time, and at such time the rights of the Holder
as holder of this Note shall  cease and the person and  persons in whose name or
names the Note Shares shall be issuable upon such conversion  shall be deemed to
have  become  the holder or  holders  of record of the Note  Shares  represented
thereby.  The Conversion  Notice shall  constitute a contract between the Holder
and the Issuer,  whereby the Holder shall be deemed to subscribe  for the number
of Note Shares that it will be entitled to receive upon such  conversion and, in
payment and  satisfaction of such  subscription  (and for any cash adjustment to
which it is entitled  pursuant to Section  3.4),  to surrender  this Note and to
release the Issuer from all liability thereon.

         SECTION  3.3  Fractional  Shares.  No  fractional  Note Shares or scrip
representing  fractional  Note Shares  shall be issued upon  conversion  of this
Note.  Instead of any  fractional  Note Shares that would  otherwise be issuable
upon  conversion of this Note, the Issuer shall pay a cash adjustment in respect
of such  fraction in an amount equal to the same  fraction of the greater of the
Current  Market  Price per Common Share at the close of business on the Business
Day that next precedes the day of conversion or the  Conversion  Price in effect
at the time of  conversion.  No  payment  or  adjustment  shall be made upon any
conversion  on account of any  distribution  on the Note Shares issued upon such
conversion.

         SECTION 3.4 Reclassification,  Consolidation, Merger or Mandatory Share
Exchange. At any time while this Note remains outstanding and unexpired, in case
of any  reclassification  or change of Outstanding  Common Shares  issuable upon
conversion of this Note (other than a change in par value,  or from par value to
no par  value  per  share,  or from no par  value per share to par value or as a

                                       -6-

result of a subdivision or combination of outstanding  securities  issuable upon
conversion  of this Note) or in case of any  consolidation,  merger or mandatory
share  exchange of the Issuer  with or into  another  corporation  (other than a
merger or mandatory share exchange with another  corporation in which the Issuer
is a continuing corporation and which does not result in any reclassification or
change,  other than a change in par value, or from par value to no par value per
share,  or from no par  value  per  share  to par  value,  or as a  result  of a
subdivision or combination of Outstanding  Common Shares upon conversion of this
Note),  or in the case of any sale or  transfer  to another  corporation  of the
property of the Issuer as an  entirety  or  substantially  as an  entirety,  the
Issuer, or such successor or purchasing corporation,  as the case may be, shall,
without payment of any additional  consideration  therefore,  execute a new Note
providing  that the Holder  shall have the right to convert  such new Note (upon
terms and conditions not less favorable to the Holder than those then applicable
to this Note) and to receive  upon such  exercise,  in lieu of each Common Share
theretofore issuable upon conversion of this Note, the kind and amount of shares
of  stock,   other   securities,   money  or  property   receivable   upon  such
reclassification,  change, consolidation, merger, mandatory share exchange, sale
or transfer by the holder of one Common Share  issuable upon  conversion of this
Note had this Note been converted  immediately  prior to such  reclassification,
change, consolidation, merger, mandatory share exchange or sale or transfer. The
provisions   of  this   Section  3.4  shall   similarly   apply  to   successive
reclassifications,  changes, consolidations,  mergers, mandatory share exchanges
and sales and transfers.

         SECTION 3.5 Adjustments to Conversion  Ratio.  For so long as this Note
is outstanding, if the Issuer (i) issues and sells pursuant to an exemption from
registration  under the  Securities  Act (A) Common  Shares at a purchase  price
representing  a percentage  of the Current  Market Price of the Common Shares on
the date of issuance  thereof  that is lower than 70%,  (B)  warrants or options
with a strike price representing a percentage of the Current Market Price of the
Common  Shares on the date of issuance of the  warrants or options that is lower
than 70%, or (C) convertible or exchangeable securities with a right to exchange
at lower than 70% of the Current  Market Price of the Common  Shares on the date
of issuance or conversion,  as applicable,  of such  convertible or exchangeable
securities; and (ii) grants the right to the purchaser(s) thereof to demand that
the Issuer  register  under the  Securities Act such Common Shares issued or the
Common  Shares  for which such  warrants  or options  may be  exercised  or such
convertible or exchangeable  securities may be converted or exchanged,  then the
Conversion  Ratio  shall  be  reduced  to equal  the  lowest  of any such  lower
percentages.

VOID UNLESS EXERCISED BEFORE 5:00 P.M., EASTERN STANDARD TIME ON ________, 1999.

                           GreenMan Technologies, Inc.

                          Common Stock Purchase Warrant


         GreenMan  Technologies,  Inc., a Delaware  corporation (the "Company"),
hereby certifies that, for value received,  ________________________________  or
assigns, is entitled, subject to the terms set forth below, to purchase from the
Company, commencing ________, 1997, at any time or from time to time before 5:00
p.m., Eastern Standard Time, on or before ________,  1999, ______ fully paid and
nonassessable  shares of Common  Stock,  $.01 par value,  of the Company,  at an
exercise  price  per  share  equal to $____.  Such  exercise  price per share as
adjusted  from  time to time as herein  provided  is  referred  to herein as the
"Exercise  Price." The number and  character  of such shares of Common Stock and
the Exercise Price are subject to adjustment as provided herein. This Warrant is
issued  pursuant to the terms of a  Securities  Purchase  Agreement of even date
herewith  between the Company and the Holder (the  "Purchase  Agreement").  This
Warrant is also the Warrant referred to in the Registration  Rights Agreement of
even date herewith between the Company and the Holder (the  Registration  Rights
Agreement).  Notwithstanding  any provision to the contrary herein, this Warrant
is subject and entitled to certain terms,  conditions,  covenants and agreements
contained in the Purchase Agreement and the Registration  Rights Agreement.  Any
transferee or transferees of the Warrant, by their acceptance hereof, assume the
obligations  of the  Holder  in  the  Purchase  Agreement  with  respect  to the
conditions and procedures for transfer of the Warrant.

         As used  herein,  the  following  terms,  unless the context  otherwise
requires, have the following respective meanings:

<PAGE>

         (a) The term "Company"  shall include  GreenMan  Technologies,  Inc., a
         Delaware corporation, and any corporation which shall succeed or assume
         the obligations of the Company hereunder.

         (b) The term "Common  Stock"  includes (a) the Company's  Common Stock,
         $.01 par value per share, as authorized, (b) any other capital stock of
         any class or classes (however designated) of the Company, authorized on
         or after such date, the holders of which shall have the right,  without
         limitation as to amount,  either to all or to a share of the balance of
         current  dividends  and  liquidating  dividends  after the  payment  of
         dividends and  distributions on any shares entitled to preference,  and
         the holders of which shall ordinarily, in the absence of contingencies,
         be entitled to vote for the  election of a majority of directors of the
         Company  (even  though the right so to vote has been  suspended  by the
         happening of such a contingency),  (c) any other  securities into which
         or for  which  any of the  securities  described  in (a) or (b)  may be
         converted  or  exchanged  pursuant  to  a  plan  of   recapitalization,
         reorganization,  merger, sale of assets or otherwise, or the conversion
         of promissory notes or other obligations of the Company.

         (c) The term "Other  Securities" refers to any stock (other than Common
         Stock)  and  other  securities  of  the  Company  or any  other  person
         (corporate or  otherwise)  which the holder of this Warrant at any time
         shall be entitled to receive,  or shall have received,  on the exercise
         of the Warrant,  in lieu of or in addition to Common Stock, or which at
         any time shall be issuable or shall have been issued in exchange for or
         in  replacement  of Other  Securities  pursuant  to  Sections 3 or 4 or
         otherwise.

         1. Exercise of Warrant.

                  1.1. Full  Exercise.  This Warrant may be exercised in full by
the holder hereof by surrender of this Warrant, with the form of subscription at
the end hereof duly  executed by such  holder,  to the Company at its  principal
office,  accompanied  by payment,  in cash,  by certified or official bank check
payable to the order of the Company or by wire  transfer to the Company,  in the
amount  obtained  by  multiplying  (a) the number of shares of Common  Stock for
which this Warrant is then exercisable by (b) the Exercise Price then in effect.

                  1.2 Partial Exercise. This Warrant may be exercised in part by
surrender of this Warrant in the manner and at the place provided in Section 1.1
except that the amount  payable by the holder on such partial  exercise shall be
the amount  obtained  by  multiplying  (a) the number of shares of Common  Stock
designated  by the  holder  in the  subscription  at the end  hereof  by (b) the
Exercise Price then in effect. On any such partial exercise,  the Company at its
expense  will  forthwith  issue and  deliver  to or upon the order of the holder
hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof
or as such holder (upon payment by such holder of any applicable transfer taxes)
may  request,  calling in the  aggregate  on the face or faces  thereof  for the
number of shares of Common Stock for which such Warrant or Warrants may still be
exercised.        

                                      -2-

<PAGE>


         2. Delivery of Stock  Certificates on Exercise.  As soon as practicable
after the exercise of this  Warrant in full or in part,  and in any event within
three (3) business days after receipt of the original Notice of Exercise and the
Warrant,  together  with  immediately  available  funds for that  portion of the
Warrant being  exercised , the Company at its expense  (including the payment by
it of any  applicable  issue  taxes)  will cause to be issued in the name of and
delivered to the holder  hereof,  or as such holder (upon payment by such holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the  number of fully  paid and  nonassessable  shares of Common  Stock (or Other
Securities)  to which such holder shall be entitled on such  exercise,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction  multiplied by the then current  market value of one
full share,  together  with any other  stock or other  securities  and  property
(including  cash,  where  applicable) to which such holder is entitled upon such
exercise pursuant to Section 1 or otherwise.

         3. Adjustment for Reorganization, Consolidation or Merger.

                  3.1  Reorganization,  Consolidation or Merger.  In case at any
time or from time to time,  the Company shall (a) effect a  reorganization,  (b)
consolidate  with or merge into any other person or entity,  or (c) transfer all
or  substantially  all of its properties or assets to any other person under any
plan or arrangement  contemplating the dissolution of the Company, then, in each
such case,  the holder of the  Warrant,  on the  exercise  hereof as provided in
Section  1  at  any  time  after  the   consummation  of  such   reorganization,
consolidation or merger or the effective date of such  dissolution,  as the case
may be,  shall  receive,  in lieu of the  Common  Stock  (or  Other  Securities)
issuable on such exercise prior to such consummation or such effective date, the
Common Stock and Other  Securities and property  (including  cash) to which such
holder would have been entitled  upon such  consummation  or in connection  with
such  dissolution,  as the case may be, if such  holder  had so  exercised  this
Warrant, immediately prior thereto, all subject to further adjustment thereafter
as provided in Sections 4 and 5.

                  3.2   Continuation   of   Terms.   Upon  any   reorganization,
consolidation,  merger or transfer (and any dissolution  following any transfer)
referred to in this  Section 3, this  Warrant  shall  continue in full force and
effect and the terms  hereof shall be  applicable  to the Common Stock and Other
Securities  and property  receivable  on the  exercise of the Warrant  after the
consummation of such  reorganization,  consolidation  or merger or the effective
date of dissolution  following any such transfer,  as the case may be, and shall
be  binding  upon the  issuer  of any  such  Common  Stock or Other  Securities,
including,  in the  case of any  such  transfer,  the  person  acquiring  all or
substantially  all of the  properties  or assets of the Company,  whether or not
such person shall have expressly assumed the terms of this Warrant.

         4. Adjustments for Stock Dividends and Stock Splits.  In the event that
the Company shall (i) issue  additional  shares of Common Stock as a dividend or
other  distribution on outstanding  Common Stock, (ii) subdivide its outstanding
shares of Common Stock,  or (iii) combine its  outstanding  shares of the Common
Stock into a smaller  number of shares of the Common  Stock,  then, in each such

                                       -3-

<PAGE>

event,  the Exercise  Price  shall,  simultaneously  with the  happening of such
event,  be adjusted  by  multiplying  the then  prevailing  Exercise  Price by a
fraction,  the  numerator of which shall be the number of shares of Common Stock
outstanding  immediately prior to such event (calculated assuming the conversion
or exchange of all outstanding shares of convertible or exchangeable  securities
of the Company that are  convertible or exchangeable  into, or exercisable  for,
shares of Common  Stock)  and the  denominator  of which  shall be the number of
shares of Common  Stock  outstanding  immediately  after such event  (calculated
assuming the conversion or exchange of all outstanding  shares of convertible or
exchangeable  securities  of the Company that are  convertible  or  exchangeable
into, or exercisable  for, shares of Common Stock),  and the product so obtained
shall thereafter be the Exercise Price then in effect. The Exercise Price, as so
adjusted,  shall be  readjusted  in the same  manner upon the  happening  of any
successive  event or events  described  herein in this  Section 4. The holder of
this Warrant shall thereafter,  on the exercise hereof as provided in Section 1,
be  entitled  to receive  that number of shares of Common  Stock  determined  by
multiplying  the number of shares of Common Stock that would  otherwise (but for
the provisions of this Section 4) be issuable on such exercise, by a fraction of
which (i) the numerator is the Exercise Price that would  otherwise (but for the
provisions  of this  Section 4) be in effect,  and (ii) the  denominator  is the
Exercise Price in effect on the date of such exercise.

         5.   Adjustment   for   Dividends   in  Other   Stock,   Property   and
Reclassifications.  In case at any time or from  time to time,  the  holders  of
Common  Stock (or Other  Securities)  shall have  received,  or (on or after the
record date fixed for the  determination  of  stockholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

         (a) other or additional  stock or other  securities or property  (other
         than  cash) by way of  dividend,  or (b) other or  additional  stock or
         other  securities  or  property  (including  cash) by way of  spin-off,
         split-up, reclassification,  recapitalization, combination of shares or
         similar corporate rearrangement,

other than additional shares of Common Stock (or Other  Securities)  issued as a
stock dividend or in a stock-split (adjustments in respect of which, in the case
of Common Stock,  are provided for in Section 4), then and in each such case the
holder of this Warrant,  on the exercise  hereof as provided in Section 1, shall
be  entitled  to  receive  the  amount  of other or  additional  stock and other
securities and property  (including cash in the cases referred to in subdivision
(b) of this Section 5) that such holder would hold on the date of such  exercise
if on the  date of  distribution  of such  other  or  additional  stock or other
securities  and  property,  or on the  record  date  fixed for  determining  the
shareholders  entitled  to  receive  such  other  or  additional  stock or other
securities and property, such holder had been the holder of record of the number
of  shares  of  Common  Stock  called  for on the face of this  Warrant  and had
thereafter, during the period from the date thereof to and including the date of
such exercise,  retained such shares and all such other or additional  stock and
other  securities  and  property  (including  cash in the cases  referred  to in
subdivision (b) of this Section 5) receivable by such holder as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Sections 3 and 4.

                                       -4-

<PAGE>

         6. Notices of Record Date. In the event of

         (a) any taking by the  Company of a record of the  holders of any class
         or securities  for the purpose of determining  the holders  thereof who
         are  entitled to receive any  dividend  or other  distribution,  or any
         right to subscribe for, purchase or otherwise acquire any shares of 
         stock of any class or any other securities or property, or to receive
         any other right, or

         (b) any capital  reorganization of the Company, any reclassification or
         recapitalization of the capital stock of the Company or any transfer of
         all or substantially  all the assets of the Company to or consolidation
         or merger of the Company with or into any other person, or

         (c) any voluntary or involuntary dissolution, liquidation or winding-up
         of the Company,

then and in each such event the  Company  will mail or cause to be mailed to the
holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the  purpose of such  dividend,  distribution  or right,  and
stating the amount and character of such dividend,  distribution  or right,  and
(ii)   the   date  on   which   any   such   reorganization,   reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up is to take place,  and the time,  if any is to be fixed,  as of which
the holders of record of Common Stock (or Other Securities) shall be entitled to
exchange  their shares of Common Stock (or Other  Securities)  for securities or
other   property   deliverable   on   such   reorganization,   reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up.  Such notice  shall be mailed at least twenty (20) days prior to the
date specified in such notice on which any such action is to be taken.

         7.  Reservation of Stock  Issuable on Exercise on Warrant.  The Company
will at all times reserve and keep  available,  solely for issuance and delivery
on the exercise of the Warrant, all shares of Common Stock (or Other Securities)
from time to time issuable on the exercise of the Warrant;  the shares of Common
Stock  which the holder of this  Warrant  shall  receive  upon  exercise  of the
Warrant will be duly authorized, validly issued, fully paid and non-assessable.

         8.  Exchange of Warrant.  On surrender  for  exchange of this  Warrant,
properly  endorsed,  to the  Company,  the Company at its expense will issue and
deliver to or on the order of the holder  thereof a new  Warrant or  Warrants of
like  tenor,  in the name of such  holder or as such  holder (on payment by such
holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

         9.   Replacement  of  Warrant.   On  receipt  of  evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant  and, in the case of any such loss,  theft or  destruction  of this

satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender and  cancellation of such Warrant,  the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         Warrant for any purpose whatsoever, nor shall anything contained herein
         be construed to confer upon such holder,  as such, any of the rights of
         a stockholder of the Company until such holder shall have exercised the
         Warrant and been issued shares of Common Stock in  accordance  with the
         provisions hereof.

         (b) The  transfer  of this  Warrant  and any  shares  of  Common  Stock
