         Notes To Unaudited Condensed Consolidated Financial Statements
                                November 30, 1997

1.       Business

         The Company  develops,  manufactures  and markets custom molded plastic
parts. The Company is also developing low-cost sources of crumb rubber recovered
from  discarded  automobile  and truck  tires and the  consumer  products  to be
manufactured from these recycled materials.

         The   Company's   wholly-owned    subsidiary,    DuraWear   Corporation
("DuraWear") manufactures,  installs and markets a diverse range of high quality
ceramic,  polymer  composite,  and alloy steel  materials  engineered  to resist
severe abrasive and corrosive conditions typically  encountered in bulk material
handling systems.

         On June 30, 1997, the Company  acquired all of the capital stock of BFI
Tire  Recyclers of Minnesota,  Inc.  ("BTM") and BFI Tire  Recyclers of Georgia,
Inc. ("BTG"),  both of which were wholly-owned  subsidiaries of  Browning-Ferris
Industries,  Inc. and are in the scrap tire collection and processing  business.
BTM and BTG have been renamed GreenMan Technologies of Minnesota,  Inc. ("GMTM")
and GreenMan Technologies of Georgia, Inc. ("GMTG"), respectively.

         On November 19, 1997, the Company  acquired all of the capital stock of
Cryopolymers,  Inc., ("Cryopolymers") a processor of scrap tire chips into crumb
rubber. The Company intends to rename  Cryopolymers as GreenMan  Technologies of
Louisiana,  Inc. and  together  with the  Company's  existing  rubber  recycling
operations  will constitute the Company's tire recycling  operations.  (See Note
3).

2.       Basis of Presentation

         The  consolidated  financial  statements  include  the  results  of the
Company,  DuraWear  and  GreenMan  Acquisition  Corporation  ("GAC") for the six
months ended November 30, 1997,  GMTM and GMTG from July 1, 1997 to November 30,
1997 and  Cryopolymers  since  November 19, 1997. All  significant  intercompany
accounts and transactions are eliminated in consolidation.

         The  financial   statements   are  unaudited  and  should  be  read  in
conjunction with the financial  statements and notes thereto for the fiscal year
ended May 31, 1997 included in the Company's Form 10-KSB/A1. Certain information
and footnote  disclosures  normally included in financial statements prepared in
accordance with generally accepted  accounting  principles has been condensed or
omitted  pursuant to the  Securities and Exchange  Commission  ("SEC") rules and
regulations,  although the Company believes the disclosures which have been made
are adequate to make the information presented not misleading.

         The results of operations for the periods  reported are not necessarily
indicative  of those that may be  expected  for a full year.  In the  opinion of
management,  all adjustments  (consisting only of normal recurring  adjustments)
which are  necessary for a fair  statement of operating  results for the interim
periods presented have been made.

3.       Acquisition of Subsidiaries

         On June  30,  1997,  GAC,  a  wholly-owned  subsidiary  of the  Company
acquired all of the capital stock of BTM and of BTG,  (renamed "GMTM" and "GMTG"
respectively),  both of which were wholly-owned  subsidiaries of Browning-Ferris
Industries,  Inc.  ("BFI")  and whose  business  is scrap  tire  collection  and
processing. The Company was also granted an exclusive option to purchase certain
assets and agreements of BFI's Ford Heights,  Illinois tire recycling  operation
which has the capacity to process between 12 and 15 million tires annually. As a
result of the acquisition, the Company's obligations under the December 14, 1995
Put-or-Pay/Take-or-Pay   agreement  for  tire  chips  and  facility  lease  were
eliminated.

         The  Company  agreed  to a pay  $5,331,517  for all of the  outstanding
capital stock of BTM and BTG of which $650,000 had been  previously  paid to BFI
as a deposit and the balance of $4,681,517 was financed by a short-term note, at
an  interest  rate of 10% from BFI to GAC,  which  loan was  originally  due and
payable on September  30, 1997.  The repayment of such note is guaranteed by the
Company and is secured by all of BTM

3.       Acquisition of Subsidiaries - (Continued)

and BTG's  assets and by a pledge by GAC of all of the capital  stock of BTG and
BTM.  In October  1997,  the  Company,  GAC and BFI entered  into a  forbearance
agreement  pursuant to which GAC agreed to pay $2,000,000 on or before  November
6, 1997 and to pay the balance under the note on or before December 6, 1997. The
Company paid $350,000 to BFI in November and an additional  $750,000 in December
(See Note 9) and has received a  commitment  letter from a third party lender to
provide permanent asset-based debt financing necessary to repay the amounts owed
to BFI.  The Company  anticipates  closing  this  financing  prior to the end of
February 1998.

         The Company also assumed $99,356 of long term notes payable  associated
with real estate tax  assessments on property  owned by BTM.  Amounts are due in
semi-annual principal installments of $15,353 plus interest at 7.29% through the
year 2002.

         The  acquisition  has been  accounted  for by the  purchase  method  of
accounting,  and  accordingly,  the net assets and results of operations of GMTM
and GMTG are included in the consolidated financial statements since the date of
acquisition.

         The following unaudited proforma financial  information  summarizes the
consolidated  results of  operations of the Company and of BTM and BTG as if the
acquisition had occurred at the beginning of fiscal 1997. The unaudited proforma
information is not  necessarily  indicative  either of the results of operations
that would have  occurred  had the  purchase  been made at the  beginning of the
fiscal year or of future results of operations of the combined companies.

</TABLE>

         On November  19,  1997,  the Company  acquired  all of the  outstanding
common stock of Cryopolymers,  Inc.,  ("Cryopolymers")  a  privately-held  crumb
rubber  producer  located in St.  Francisville,  Louisiana.  The purchase  price
consisted  of (1)  $550,000 in shares of common stock based upon the closing bid
price the day prior to closing;  (2) 200,000  shares of common stock,  valued at
$194,000 or $.97 per share; (3) warrants to purchase  1,200,000 shares of common
stock  exercisable  commencing  April 1, 1998 for period of five years at prices
ranging from $3.00 to $7.00 per share;  and (4) additional  warrants to purchase
100,000  shares of common  stock  exercisable  at $.97 per share for a period of
five years and vesting 25% immediately and 25% each successive six month period.
The Company has  determined the total purchase price to be $775,000 based upon a
$.97 closing  price of the common stock prior to the closing and a $31,000 value
ascribed to the 1,300,000 warrants issued pursuant to SFAS No. 123,  "Accounting
for Stock-Based Compensation" ("SFAS No. 123").

         The acquisition  has been accounted for as a purchase and  accordingly,
the net  assets of  Cryopolymers  are  included  in the  consolidated  financial
statements  since  November  19,  1997.  Goodwill  was  recorded  as  the  total
consideration  paid by the Company  exceeded the fair value of the net assets of
Cryopolymers  by  $100,000.  Goodwill  is  being  amortized  over 10  years on a
straight line basis.

4.       Net Loss Per Share

         Net loss per share is based on the  weighted  average  number of common
shares outstanding during the period.

5.       Joint Venture

         On August 26,  1997,  the Company  finalized  the  formation of a joint
venture ("the joint venture") between the Company and Crumb Rubber Technologies,
Inc. of Jamaica,  New York ("CRT"), to collect and process tires in the State of
New York and to market  the  crumb  rubber  derived  from the  tires.  The joint
venture will address existing opportunities for larger mesh crumb rubber such as
in  rubber  mats,  ground  cover and as a filler in  asphalt  applications.  The
Company has contributed  it's investment in the cryogenic crumb rubber equipment
($400,000)  which was formerly  located in Jackson,  Georgia into the venture as
its  capital  contribution  while  CRT  will  contribute  on  its  part  certain
facilities,  equipment,  customer  contracts,  licenses  and permits and provide
operational and technical expertise.

         Pursuant to the terms of the joint venture  agreement,  CRT is required
to return $300,000 of equipment deposits  previously made by the Company towards
the  purchase  of  additional  cryogenic  crumb  rubber  equipment.  The Company
received the first $100,000 installment in September 1997. The remaining balance
is to be repaid over a six month period.

6.       Convertible Notes Payable

         In January  1997,  the Company  concluded a  $1,525,000  offering of 7%
convertible  subordinated  debentures  ("Debentures")  and  warrants to purchase
762,500 shares of common stock (the "January  Offering") at an exercise price of
$1.25 per share. The Debentures are convertible after a sixty day holding period
into  shares of common  stock at a  conversion  price  equal to the lower of the
closing  bid price on the date of the  January  Offering  closing  or 70% of the
closing bid price on the date prior to the  conversion of such  Debentures.  The
Company has recorded a deferred charge of approximately $654,000 associated with
the impact of the 30% discount from market to be realized upon conversion of the
debentures. The Company recorded non-cash deferred financing costs of $75,000 in
connection  with the issuance of the warrants to purchase  762,500  shares.  The
Company  also  recorded  non-cash  deferred   financing  costs  of  $695,000  in
connection with the issuance of warrants to purchase  1,050,000 shares of common
stock to the placement  agents in accordance  with SFAS No. 123. At November 30,
1997, all  Debentures had been converted into 2,493,201  shares of the Company's
common  stock and all  deferred  charges had been  amortized  to expense.  As of
November 30, 1997,  investors  from the January  Offering had exercised  180,000
warrants resulting in net proceeds to the Company of $225,000.

         In  April  1997,  the  Company  concluded  a  $1,500,000   offering  of
convertible  notes (the "Notes') due eighteen  months after closing and warrants
to purchase  300,000  shares of common stock (the "April  Offering") at exercise
prices ranging from $.97 to $1.05.  The Notes are convertible  after a sixty day
holding  period into shares of common stock at a  conversion  price equal to the
lower of the average  closing bid prices on the five trading days  preceding the
date of the April Offering  closing or 70% of the average  closing bid prices on
the five trading days  preceding  the date of the  conversion  of the Notes upon
conversion.  Upon  conversion,  the note  holders  receive  4,000  shares of the
Company's common stock in lieu of interest for each $100,000 converted.  The net
proceeds from the April Offering were  approximately  $1,247,000 after deducting
commissions and expenses of

6.       Convertible Notes Payable -(Continued)

approximately $253,000. The Company also issued immediately exercisable two year
warrants to purchase 154,839 shares of common stock at an exercise price of $.97
per share to the placement  agents.  The Company  recorded a deferred  charge of
approximately  $643,000  associated  with the  impact of the 30%  discount  from
market to be realized upon  conversion  of the Notes.  The Company also recorded
deferred  financing costs of $64,600 in connection with the issuance of warrants
to purchase 454,839 shares of common stock to the investors and placement agents
in accordance with SFAS No. 123. These deferred charges are being amortized over
the estimated life of the notes. As of November 30, 1997,  $386,000 of the notes
had been converted into 589,403 shares of common stock  including  15,440 shares
associated with accrued interest.

         Pursuant to the terms of the notes,  the Company  filed a  Registration
Statement  on Form  S-3 in May 1997 to  register  the  shares  of  common  stock
issuable upon conversion of the notes,  payment of interest and upon exercise of
the warrants to purchase  454,839  shares of common stock.  Effective July 1997,
the Company is required to pay the investors 2.5% of their principal  investment
per month as a penalty for each month or portion  thereof  prior to the date the
Form S-3 is  declared  effective.  The Form S-3 was  declared  effective  by the
Securities  and Exchange  Commission  on November 12, 1997. At November 30, 1997
the Company has recorded  $162,500 of  additional  financing  costs  pursuant to
these terms.

7.       Notes Payable, Related Parties

         During June and July 1997, the Company borrowed an additional  $386,000
from four officers of the Company and issued  warrants to purchase 77,200 shares
of common  stock at exercise  prices  ranging  from $.72 to $.97 per share.  The
notes are  convertible  after a one hundred  and twenty day holding  period into
shares of common stock at a  conversion  price equal to the lower of the average
closing bid price on the five trading days  preceding  the closing or 70% of the
average  closing bid prices on the five trading days  preceding  the date of the
conversion of such notes.  The Company  recognized a deferred charge of $166,002
associated  with the impact of the 30% discount  from market to be realized upon
conversion and $7,800 of non-cash  deferred  financing  costs in connection with
the issuance of the warrants to the officers to purchase 77,200 shares of common
stock in accordance with SFAS No. 123.

         On November 25, 1997, Palomar Medical  Technologies,  Inc.  ("Palomar")
converted  $200,000 of principal  and $22,685 of accrued  interest  into 222,685
shares of common stock pursuant to the terms of its $1,200,000  convertible note
payable.  In January 1998, Palomar converted an additional $200,000 of principal
and $25,452 of accrued interest into 225,452 shares of common stock. The Company
has received an extension until January 31, 1998 to pay the remaining balance of
the convertible note.

8.       Capital Leases

         At November 30, 1997,  the Company was eight months past due on amounts
due under its injection molding equipment leases. Past due principal payments at
November 30, 1997 amounted to $314,000. Accordingly, the lessor has the right to
demand the payment of all amounts due under the past due lease  agreements.  The
Company is currently  negotiating new payment terms with the lessor for past due
amounts (See Note 9) and as of January 16, 1998 has not received notification of
the lessor's  intent to exercise  any of the default  remedies  available.  As a
result of the  default,  the Company has  classified  all payments due under the
affected leases as current liabilities at November 30, 1997.

         Effective  October  1997,  the  Company  entered  into  a  fifteen-year
cryogenic equipment lease agreement with Cryopolymer's  Leasing,  Inc., a former
stockholder of Cryopolymers. Under the terms of the agreement, Cryopolymers will
pay $25,500 per month  rental plus an  additional  rent of $100,000 per year for
the first six years of the agreement to be payable in the Company's common stock
with the number of shares  determined  using the closing bid price of the common
stock on each  December 31. The lease has been  classified as a capital lease at
November 30, 1997 and has a value of $3,063,000.

9.       Subsequent Events

Shutdown of Injection Molding Operations

         The Company has determined that it will  discontinue  operations at its
Malvern,  Arkansas  facility  (the  "facility').  The  facility  is  engaged  in
providing injection molding  manufacturing  services to customer  specifications
("Contract/Custom  molding")  in the  production  of plastic  and  thermoplastic
rubber parts for such products as stereo components and speakers,  water filters
and pumps, plumbing components and automotive accessories.

         During the year ended May 31, 1997,  the  facility's  revenues  totaled
$1,936,450 and had net losses  totaling  $589,094.  For the three and six months
ended  November 30, 1997,  the  facility's  revenues were $327,760 and $895,831,
respectively   and  the  facility's  net  losses  were  $297,536  and  $444,570,
respectively.  For the  three  and six  months  ended  November  30,  1996,  the
facility's  revenues were $227,461 and $645,922,  respectively  and the facility
had net losses of $215,325 and  $439,083,  respectively.  For the year ended May
31, 1997 and the three and six months ended  November 30, 1997,  the  facility's
revenues represented 48%, 10% and 15% , respectively of consolidated revenue and
38%, 30% and 21% of the  Company's  consolidated  net loss.  At May 31, 1997 and
November 30, 1997, the  facility's  assets  totaled  $3,411,979 and  $3,055,558,
respectively, and represented 45% and 17% of consolidated assets.

         The Company is currently exploring several alternatives with respect to
the facility: (1) the sale of the entire operation;  (2) the contribution of the
facility's  assets into a joint  venture;  or (3) the relocation of a portion of
the facility's  assets to other Company  locations and the sale of any remaining
assets.  The Company is currently in discussions with several parties  regarding
one or more of the  following  alternatives;  however,  it has not  reached  any
understandings or agreements with any party.

         The Company  has not  adopted a formal plan to dispose of the  facility
and as a result,  is unable to ascertain the financial impact on disposal of the
assets.

Convertible Notes Payable

         In December 1997, the Company received  $1,600,000 in an offering of 8%
convertible  debentures and warrants to purchase  160,000 shares of common stock
(the "December  Offering") at an exercise  price of $.69 per share.  The Company
received  a  commitment  from  the  December  Offering  investors  for  up to an
additional $2,000,000 of financing under similar terms for a period of 12 months
following the December Offering closing.  The debentures are convertible after a
sixty day holding period into shares of common stock at a conversion price equal
to the  lower  of the  average  closing  bid  prices  on the five  trading  days
preceding  the  date of the  December  Offering  closing  or 75% of the  average
closing bid prices on the five trading days preceding the date of the conversion
of the debentures.  The debentures  automatically  convert into shares of common
stock upon maturity.

         The  net  proceeds  from  the  December  Offering  were   approximately
$1,350,000 after deducting  commissions and expenses of approximately  $250,000.
The Company paid $750,000 from the proceeds to BFI towards the outstanding  loan
payable for the  purchase of GMTM and GMTG.  The Company has recorded a deferred
charge of approximately  $533,000 associated with the impact of the 25% discount
from market to be realized upon conversion of the  debentures.  The Company also
recorded deferred  financing costs of $32,000 in connection with the issuance of
warrants  to  purchase  320,000  shares of  common  stock to the  investors  and
placement agents in accordance with SFAS No. 123. The deferred charges are being
amortized over the estimated life of the debentures.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

         The  following  information  should  be read in  conjunction  with  the
unaudited  condensed  consolidated  financial  statements  and the notes thereto
included  in  Item 1 of the  Quarterly  Report,  and  the  audited  consolidated
financial statements and notes thereto and Management's  Discussion and Analysis
of Financial Condition and Results of Operations contained in the Company's Form
10-KSB filed for the fiscal year ended May 31, 1997.

Overview

         GreenMan Technologies, Inc. (the "Company" or "GreenMan") was formed to
primarily develop,  manufacture and sell "environmentally  friendly" plastic and
thermoplastic  rubber parts and products that are  manufactured  using  recycled
materials and/or are themselves partially or wholly recyclable.

         The Company's Molding operation (the "Molding  operation"),  located in
Malvern,   Arkansas,   provided  injection  molding  manufacturing  services  to
customers'  specifications in the production of plastic and thermoplastic rubber
parts.  The facility also  conducted  research and  development on the Company's
GreenMan  Environmental  Materials  ("GEM")  Stock and  tested  the use of these
materials in the manufacture of a variety of potential products. As discussed in
Note 9, the Company  has  decided  effective  December  31, 1997 to  discontinue
operations  at the  Malvern  facility.  Management  believes  that  third  party
contract manufacturers can provide the Company with equivalent injection molding
capabilities at equal or less cost.

         On October 10, 1995, the Company acquired all of the outstanding common
stock  of  DuraWear  Corporation  ("DuraWear").  DuraWear  which is  located  in
Birmingham, Alabama, manufactures,  installs and markets a diverse range of high
quality  ceramic,  polymer  composite,  and alloy steel materials  engineered to
resist severely abrasive and corrosive conditions typically  encountered in bulk
material  handling  systems in such industries as paper and pulp,  mining,  coal
handling and grain storage and transportation..

         On June 30, 1997, the Company acquired BFI Tire Recyclers of Minnesota,
Inc. and BFI Tire Recyclers of Georgia,  Inc., (renamed GreenMan Technologies of
Minnesota,  Inc. ("GMTM") and GreenMan  Technologies of Georgia,  Inc. ("GMTG"),
respectively)  which  provides  the  Company  access  to over 10  million  tires
annually.  The Company was also granted an exclusive  option to purchase certain
assets and agreements of BFI's Ford Heights,  Illinois tire recycling  operation
which has the capacity to process between 12 and 15 million tires annually.  The
acquired  operations are in the scrap tire  collection  and processing  business
whereby they charge a fee to dispose of customers'  scrap tires and then process
the tires into two inch  rubber  chips which are then sold as  alternative  fuel
("TDF" - Tire  Derived  Fuel) to  cement  kilns,  paper and pulp  producers  and
electric utilities;  or utilized in civil engineering  projects such as landfill
construction (leach-bed lining), soil erosion and road stabilization projects.

         On November  19,  1997,  the Company  acquired  all of the  outstanding
common stock of Cryopolymers,  Inc.,  ("Cryopolymers")  a  privately-held  crumb
rubber producer located in St. Francisville, Louisiana. The Company has targeted
several  markets with products  incorporating  significant  amounts of recovered
crumb  rubber  and  plastic  waste,   including  the  building   industry  (with
anti-fatigue  floor mats,  roofing products,  and timbers);  the lawn and garden
market  (with  landscape  timbers);  the  consumer  products  market (with trash
containers,  recycling totes, and storage  containers);  and the  transportation
industry (with rubber modified asphalt, nose cones, barriers,  railroad ties and
railway crossing mats).

Results of Operations

         Three Months ended November 30, 1997 Compared to the Three Months ended
November 30, 1996

         Net sales for the three months ended November 30, 1997 were  $3,389,338
as compared to $796,141  for the three  months  ended  November  30,  1996.  The
increase of  $2,593,197  or 326% was  primarily due to the inclusion of revenues
from GMTM and GMTG which collectively totaled $2,333,716.

         Gross profit for the three months ended  November 30, 1997 was $877,402
or 26% of net  sales as  compared  to  $67,633  or 8% of net sales for the three
months ended  November 30, 1996.  The  improvement in gross profit was primarily
due to the inclusion of GMTM and GMTG operations  which averaged 27% of revenues
and gross profits from DuraWear's operations which generated a 53% gross margin.
Also  contributing to the improvement in gross profit was the elimination of the
Company's  "take  or  pay"  tire  chip  obligation  (as a  result  of  the  GMTG
acquisition)  which  expense  totaled  $112,500  during the three  months  ended
November 30, 1996.  These  collective  increases offset a gross loss of $125,045
associated with the Company's  molding  operations during the three months ended
November 30, 1997.

         Research  and  development  expenditures  were $ 56,735  for the  three
months  ended  November  30,  1997 as compared to $50,321 for the same period in
1996.  The increase is  attributable  to the  Company's  continued  research and
development  efforts  in  identifying  applications  for  ultra-fine  mesh crumb
rubber.

         Selling,  general and  administrative  expenses were $1,178,028 for the
three months ended  November 30, 1997,  or 35% of sales as compared to $807,551,
or 101% of sales,  for the same period in 1996.  The  increase  of $370,477  was
primarily  attributable to the inclusion of GMTM and GMTG's collective operating
expenses of $303,963 and increased professional expense associated with the GMTM
and GMTG acquisition.

         As a result of the  foregoing,  the operating loss for the three months
ended  November  30, 1997  decreased  by $432,878 to $357,361 or 11% of sales as
compared to an operating  loss of $790,239,  or 99% of sales for the  comparable
period  in 1996.  Approximately  $258,000  of the  operating  loss for the three
months  ended  November  30,  1997 was  attributable  to the  Company's  molding
operations which were discontinued effective December 31, 1997.

         Interest and financing  costs  increased by $537,554 to $621,861 due to
increased  borrowings  related to the  issuance  of  $3,665,000  in  convertible
debentures during fiscal 1997 and an additional  $386,000 in fiscal 1998 and the
inclusion of $124,313 of interest owed on the note payable to BFI. Approximately
$287,398 of the increase is  associated  with the impact of  amortizing  the 30%
discount  from market to be  realized  upon  conversion  of the  debentures  and
financing expense amortization associated with the borrowings.  The Company also
recognized  $87,500 of additional  financing  costs pursuant to the terms of the
debentures as a result of the delay in  registering  under the Securities Act of
1933 the common stock issuable upon  conversion of the debentures  issued in the
April 1997 offering.

         The Company  experienced a net loss of $982,802,  or $.12 per share for
the quarter  ended  November 30, 1997 as compared to a net loss of $892,361,  or
$.16 per share for the quarter ended November 30, 1996.

Results of Operations

Six Months ended November 30, 1997 Compared to the Six Months ended November 30,
1997

         Net sales for the six months ended November 30, 1997 were $6,104,668 as
compared to $1,683,007  for the six months ended November 30, 1996. The increase
of  $4,421,661  or 263% is due to the  inclusion of revenues  from GMTM and GMTG
which  collectively  totaled  $3,995,381  and a $75,842  increase in  DuraWear's
revenue.

         Gross profit for the six months ended  November 30, 1997 was $1,610,995
or 26% of net  sales as  compared  to  $228,460  or 14% of net sales for the six
months ended  November 30, 1996.  The  improvement in gross profit was primarily
due to the inclusion of GMTM and GMTG operations  which averaged 29% of revenues
and gross profits from DuraWear's operations which generated a 51% gross margin.
Also  contributing to the improvement in gross profit was the elimination of the
Company's  "take  or  pay"  tire  chip  obligation  (as a  result  of  the  GMTG
acquisition)  which  expenses  totaled  $225,000  during  the six  months  ended
November 30, 1996. These collective  increases offset a negative gross profit of
$113,587  associated with the Company's molding operations during the six months
ended November 30, 1997.

         Research and development expenditures were $ 139,050 for the six months
ended November 30, 1997 as compared to $117,406 for the same period in 1996. The
increase is  attributable  to the Company's  continued  research and development
efforts in identifying applications for ultra-fine mesh crumb rubber.

         Selling,  general  and  administrative  expenses  decreased  $20,187 to
$2,017,510  for the six months ended November 30, 1997 as compared to $2,037,697
for the same 1996 period. The results for the six months ended November 30, 1997
reflect  $492,721 of expenses  associated  with the  inclusion  of GMTM and GMTG
since  July 1, 1997 and  increased  professional  expenses  associated  with the
acquisition.  This  increase  was  offset by the  elimination  of  approximately
$455,000 of  one-time  expenses  incurred in the same period in 1996  associated
with a significant  financial public relations campaign and the non-cash expense
in  connection  with the  issuance  of common  stock  warrants  and  options  in
accordance with SFAS No. 123,  "Accounting for Stock- Based  Compensation".  The
results for the six months ended  November 30, 1996 also  reflected  $266,880 of
costs associated with the Company's recycling operation which had been operating
under limited conditions.

         As a result of the  foregoing,  the  operating  loss for the six months
ended  November 30, 1997  decreased by  $1,381,078 to $545,565 as compared to an
operating loss of $1,926,643 for the comparable period in 1996.

         Interest and financing costs increased by $ 1,345,509 to $1,525,114 due
to increased  borrowings  related to the issuance of $3,665,000  in  convertible
debentures during fiscal 1997 and an additional  $386,000 in fiscal 1998 and the
inclusion of $205,552 of interest owed on the note payable to BFI. Approximately
$933,971 of the increase is  associated  with the impact of  amortizing  the 30%
discount  from market to be  realized  upon  conversion  of the  debentures  and
financing expense amortization associated with the borrowings.  The Company also
recognized  $162,500 of additional  financing costs pursuant to the terms of the
debentures as a result of the delay in  registering  under the Securities Act of
1933 the common stock issuable upon  conversion of the debentures  issued in the
April 1997 offering.

         The Company experienced a net loss of $2,082,543, or $.26 per share for
the six months ended  November 30, 1997 as compared to a net loss of $2,157,341,
or $.41 per share for the six months ended November 30, 1996.

Liquidity and Capital Resources

         Since its inception, the Company has satisfied its capital requirements
through the sale of common and preferred stock and debt securities to investors,
loans from affiliated and unaffiliated lenders, the acquisition of machinery and
equipment  through capital leases and notes payable,  and the issuance of common
stock  and  common  stock  options  and  warrants  in lieu of cash for  services
rendered.

         During June and July 1997, the Company borrowed an additional  $386,000
from four officers of the Company and issued  warrants to purchase 77,200 shares
of common  stock at exercise  prices  ranging  from $.72 to $.97 per share.  The
notes are  convertible  after a one hundred  and twenty day holding  period into
shares of common stock at a conversion  prices equal to the lower of the average
of the closing bid prices on the five trading days  preceding the closing or 70%
of the average of the closing bid prices on the five trading days  preceding the
date of the conversion of such notes.

         During the six months  ended  November  30,  1997,  investors  from the
January  Offering  exercised  180,000 warrants to purchase common stock at $1.25
per share.

         Pursuant  to the  terms of the  joint  venture  agreement  between  the
Company and Crumb Rubber  Technologies,  Inc.  ("CRT"),  in  September  1997 the
Company received the first of three $100,000  installments towards the refund of
equipment deposits.

         At November  30,  1997,  the Company  had cash of  $859,794,  a working
capital deficit of $7,193,460,  net capital of $1,539,774 and accumulated losses
of $12,787,476.  The working capital deficit includes  $1,000,000 of convertible
notes payable and approximately  $1,833,000 relating to the  reclassification of
certain long term capital lease  obligations to current as several leases are in
default.  These  leases  relate  to  equipment  used  in the  Company's  Molding
operations.  The  Company  is  currently  working  with the  lessor to bring its
obligations  current and has not  received  any written or verbal  notice of the
lessors intention to enforce the default  provisions.  In January 1998, $200,000
of the convertible  notes payable and $24,250 of accrued interest were converted
into 224,250 shares of common stock. The Company  anticipates that the remaining
convertible  notes payable  outstanding  balances will be converted  into common
stock pursuant to their respective terms in lieu of repayment.

         In December 1997, the Company concluded $1,600,000 in an offering of 8%
convertible  debentures and warrants to purchase  160,000 shares of common stock
(the "December  Offering") at an exercise  price of $.69 per share.  The Company
received  a  commitment  from  the  December  Offering  investors  for  up to an
additional $2,000,000 of financing under similar terms for a period of 12 months
following the December Offering closing.  The debentures are convertible after a
sixty day holding period into shares of common stock at a conversion price equal
to the  lower  of the  average  closing  bid  prices  on the five  trading  days
preceding  the  date of the  December  Offering  closing  or 75% of the  average
closing bid prices on the five trading days preceding the date of the conversion
of the debentures.  The debentures  automatically  convert into shares of common
stock  upon  maturity.   The  net  proceeds  from  the  December  Offering  were
approximately   $1,350,000   after   deducting   commissions   and  expenses  of
approximately  $250,000.  The Company  paid  $750,000  from the  proceeds to BFI
towards the  outstanding  note payable for the purchase of GMTM and GMTG and has
received a  commitment  letter  from a third party  lender to provide  permanent
asset-based  debt  financing  necessary  to repay the amounts  owed to BFI.  The
Company anticipates closing this financing prior to the end of February.

         Based on the Company's  operating  plans  management  believes that the
available  working capital  together with revenues from  operations,  the equity
financing commitment secured in December 1997, the purchase of equipment through
lease  financing  arrangements  and the successful  refinancing of the BFI short
term note will be sufficient to meet the Company's cash requirements through the
end of fiscal  1998.  The Company  expects  that  additional  financing  will be
required  after  this time in order to fund  continued  growth.  Management  has
identified and is currently evaluating several immediate financing  alternatives
and  diligently  working to determine the  feasibility of each  alternative.  No
assurances can be given that such financing will be concluded in the near future
on  favorable  terms,  if at all. If the Company is unable to obtain  additional
financing,  its ability to maintain  its current  level of  operations  could be
materially and adversely  affected and the Company may be required to adjust its
operating plans accordingly.

Factors Affecting Future Results

         The Company's  revenue and operating results may fluctuate from quarter
to quarter and from year to year due to a combination of factors,  including (i)
refacilitation  of the  Company's  crumb  rubber plant and  production  of crumb
rubber in  commercial  quantities  at a price  that will be  competitive  in the
market;  (ii) the  Company's  ability  to secure  additional  customers  for its
products,  thereby  reducing  its reliance on a few major  customers;  (iii) the
Company's ability to refinance the GMTM and GMTG acquisition  related short term
note and the Company's  ability to integrate and manage the  operations of GMTM,
GMTG and  Cryopolymers,  Inc., its recently acquired  subsidiaries;  (iv) market
acceptance of the Company's  proposed GEM Stock  material and GreenMan  consumer
products; (v) ability to obtain raw materials from suppliers on terms acceptable
to the Company;  and (vi) general economic  conditions.  The Company's plans and
objectives,  are based on assumptions  that it will be successful in integrating
the operations of GMTM,GMTG and  Cryopolymers,  Inc., that it will produce crumb
rubber at a price that will be competitive in the market,  that the Company will
be successful in receiving  additional  financing to fund future growth and that
there  will  be no  material  adverse  change  in the  Company's  operations  or
business.

         Assumptions  relating to the foregoing  involve  judgments with respect
to, among other things, future economic,  competitive and market conditions, all
of which are difficult or impossible to predict accurately and many of which are
beyond the control of the Company.  As a result,  there can be no assurance that
the Company will be able to achieve or sustain  profitability  on a quarterly or
annual  basis.  In  light  of  the  significant  uncertainties  inherent  in the
Company's business, forward-looking statements made in this report should not be
regarded  as a  representation  by the  Company  or any  other  person  that the
objectives and plans of the Company will be achieved.

Messer Griesheim Industries,  Inc. (hereinafter referred to as the "Seller") and

                                 II. AGREEMENTS

         In consideration of the covenants,  warranties,  and mutual  agreements
herein  set  forth,  and in  reliance  upon the  representation  and  warranties
contained herein, the parties do hereby agree as follows:

         1. Sale. Subject to all the terms and conditions of this Agreement, the
Seller  hereby sells,  assigns,  transfers,  and delivers to Purchaser,  and the
Purchaser hereby  purchases the "Collective  Shares" which represent 51% percent
of the issued and outstanding  shares of the common stock of the Company on this
date. Seller represents to Purchaser that no stock  certificates  evidencing the
Collective  Shares  were  received  by  Seller  from  the  Company.  The  Seller
acknowledges  that the Collective Shares represent all the shares of the Company
to which it was  entitled and agrees to release the Company and  Purchaser  from
any and all  claims  for any shares of the  Company  other  than the  Collective
Shares.

         2. Purchase Price. In consideration  of the sale of Collective  Shares,
and subject to the conditions hereafter set forth,  Purchaser agrees to issue to
Seller  shares of Common  Stock,  $.01 par value per share,  of  Purchaser  (the
"Purchaser  Shares").  The number of  Purchaser  Shares to be issued shall be an
amount equal to 100,000 shares plus a number of additional  shares determined by
dividing  $550,000 by the closing price of Purchaser's  Common Stock as reported
by the NASDAQ  Small-Cap  Market in the Wall Street  Journal on the last trading
day  immediately  prior to the day of the  closing of this  transaction  (Act of
Sale). In the event that the number of Purchaser Shares  calculated  pursuant to
the  forgoing  formula  results in a fractional  share,  the number of Purchaser
Shares to be issued to Seller  shall be  rounded  to the next  whole  share.  In
addition,  the number of Purchaser Shares issuable to Seller shall be subject to
adjustment for events such as a  reorganization,  consolidation or merger of the
Purchaser, a stock

                                        2

split or stock dividend made by the Purchaser, or a similar event.  Accordingly,
Seller shall be entitled to the same rights with respect to the Purchaser Shares
as granted to  Purchaser  in  Sections 3, 4 and 5 of the Common  Stock  Purchase
Warrant of even date herewith issued by Purchaser to Seller.

         Seller  understands  and  agrees  that a  meeting  of  shareholders  of
Purchaser  is  required to approve an increase in the number of shares of Common
Stock  authorized  under  Purchaser's  Certificate  of  Incorporation  prior  to
delivery of the Purchaser Shares. In the event that shareholder  approval is not
obtained by Purchaser, Purchaser shall pay to Seller no later than April 1, 1998
the sum of  $650,000.00  plus  interest on said sum at the rate of eight percent
(8%) per annum  (calculated  from the date of this Act of Sale until the payment
date) in cash or in Common Stock of Purchaser, valued as in this paragraph.

         Purchaser also agrees that it will register the Purchaser  Shares under
the  Securities  Act of 1933,  as  amended,  as soon as  practicable  after  the
shareholders   approve  the   amendment   to  the   Company's   Certificate   of
Incorporation,  provided  however,  that such  registration  shall only occur in
connection  with the  registration  of other shares of Common Stock of Purchaser
that the Purchaser is required to register at the time.

                           Company  to allow  Purchaser  to  obtain  competitive

                           facility (the "Facility");

                           match the lowest bona fide written  competitive offer

                           to  request  from  Purchaser  and to  review  and has
                           received all  information  which it deems relevant in

full access,  during normal  business  hours  throughout the period prior to the

         THE  AGREEMENT  made as of the  _______ day of  _______,  1997,  by and
between Cryopolymers Leasing, Inc. (hereinafter referred to as the "Seller") and
GreenMan  Technologies,  Inc.  (hereinafter  referred  to as  the  "Purchaser").

Recitals:

         1. There are presently  1,000 shares of issued and  outstanding  common
stock of the Company out of 10,000  shares  authorized.  There are  presently no
treasury shares held by the Company.

         2. The Seller is the owner of 270  shares of the issue and  outstanding
common stock of Cryopolymers, Inc.

         3. The Seller desires to sell to Purchaser,  and the Purchaser, and the
Purchaser  desires to purchase 270 issued and outstanding  shares (the "Shares")
of the common stock of the Company.

         4. The Shares  represent  27%  percent  of the  issued and  outstanding
common stock of the Company.

         5. The sale contemplated hereby is contingent upon Purchaser purchasing
a majority of the issued and outstanding shares of the Company.

Agreements:

         In consideration of the covenants,  warranties,  and mutual  agreements
herein  set  forth,  and in  reliance  upon the  representation  and  warranties
contained herein, the parties do hereby agree as follows:

                                                      

<PAGE>


1.       Sale of Shares; Consideration.

         1.01 Sale.  Subject to all the terms and conditions of this  Agreement,
the Seller hereby sells, assigns,  transfers, and delivers to Purchaser, and the
Purchaser  hereby  purchases  the "Shares"  which  represent  27% percent of the
issued and  outstanding  shares of the common stock of the Company on this date.
These shares are evidences by stock  certificate  number  _______which  has been
duly endorsed by Seller and  delivered to Purchaser,  receipt of which is hereby
acknowledged.

         1.02  Purchase  Price.  In  consideration  of the sale of  Shares,  and
subject  to the  conditions  hereinafter  set forth,  Purchaser  pays to Seller,
receipt of which is hereby acknowledged by Seller, as follows:

         1.       100,000 shares of GreenMan Technologies, common stock.
         2.       In further consideration of the sale of shares,  Purchaser and
                  Seller  have  entered   into  a  new  lease,   contemporaneous
                  herewith, attached as Exhibit "A".

         1.03 Right of First  Refusal and Stock  Transfer  Restrictions.  Seller
understands  that any stock  transferred  by virtue of this  Agreement or by the
Equipment Lease executed by and between them may result in Seller holding at any
given time, a significant  number of shares in GreenMan  Technology  Stock ("the
Stock").  Any sale of a large block of the stock (in excess of 30,000 shares) or
any series of trades  constituting  a large  block,  could  result in a material
disruption in the share price or in the trading of GreenMan  Technology Stock in
the hands of other  shareholders.  Seller agrees that in the event of its intent
to sell any shares of the stock,  it shall first offer these  shares to GreenMan
Technologies. The price of the block shall be that price which a bona fide third
party  purchaser  is, or will be willing  to pay for the block of shares  Seller
wishes to sell. If GreenMan elects not to purchase the block of shares

                                       -2-

<PAGE>



within fifteen (15) days, Seller may then sell the block to the third party bona
fide purchaser on the same terms and  conditions  offered by Seller to GreenMan.

2.  Arbitration.  Any  and  all  claims  or  controversies  arising  out of this
Agreement shall be submitted to and settled by binding  arbitration in Louisiana
in accordance with the commercial rules of the American Arbitration  Association
then in effect,  and judgment upon the award rendered in such arbitration may be
entered  in any court  having  jurisdiction  over the claim or  controversy.  

3.  Access  and  Information.  The  Seller  has  caused  the  Company to give to
Purchaser and to Purchaser's  attorney,  accountants,  and other representatives
full access,  during normal  business  hours  throughout the period prior to the
date first above written, to all of the Company's properties,  books, contracts,
commitments,  and records,  and has  furnished and will continue to furnish such
information  concerning the Company's affairs as Purchaser has or may reasonably
request.  Purchaser  warrants  that it has  made  its own  investigation  of the
affairs of the Company and is not relying on any  representation  or warranty of
Seller or Company,  it being expressly  agreed that no such  representations  or
warranties were given.

4. Purchase of Interest in Business. The Purchaser represents that its purchaser
hereunder  is being made for its own  account and with no present  intention  of
resale. The parties hereto intend that the purchase of stock evidenced hereby is
actually the purchase of an interest of the business conducted by the Company.

                                 EQUIPMENT LEASE


         This  lease,  effective  as of the last date  stated  below,  is by and
between CRYOPOLYMERS  LEASING,  INC., of 500 Kirby Street, City of Lake Charles,
Parish of Calcasieu,  State of Louisiana,  referred to as "Lessor", and GREENMAN
TECHNOLOGIES,  INC., of 7 Kimball Lane, Building A, City of Lynnfield,  State of
Massachusetts, referred to as "Lessee."

                                   SECTION ONE
                                 PROPERTY LEASED

         Lessor  leases to Lessee,  and Lessee  leases from Lessor,  the movable
property described in Exhibit "A", attached to and made a part of this agreement
(the "property").

                                   SECTION TWO
                                  TERM OF LEASE

         The  term of  this  lease  shall  be for a  fifteen  (15)  year  period
commencing on August 1, 1997, and ending on July 31, 2112.

                                  SECTION THREE
                                      RENT

         Lessee agrees to pay Lessor,  as rent for the property,  both base rent
and bonus  rent.  Rent for the term of the lease  shall be monthly  payments  of
$25,500.00 payable in advance on or before the first day of each month until the
termination of the lease.

         In  addition  to the base rent,  a bonus rent shall be paid on the last
day of each successive year for a six (6) year period  beginning on December 31,
1997 and ending December 31, 2002. The bonus rent shall be that amount of common
stock of  Lessee,  the  value of which is equal to the sum of  $100,000.00.  The
closing bid price as reported by the "NASDAQ" market on the last


<PAGE>


                                       -2-

reporting  day  immediately  prior to the date the bonus  payment is due will be
used to determine the value of the common stock payable as bonus rental.

         Right  of  First  Refusal  and  Stock  Transfer  Restrictions.   Lessor
understands that any stock  transferred by virtue of this Agreement,  the Act of
Sale, or by the  Non-Qualified  Stock Option  Agreement  executed by and between
them may result in Lessor  holding at any given time,  a  significant  number of
shares in GreenMan Technology Stock (the "Stock").  Any sale of a large block of
the stock (in  excess of ____  shares) or any  series of trades  constituting  a
large block, could result in a material  disruption in the share price or in the
trading of GreenMan Technology Stock in the hands of other shareholders.  Lessor
agrees that in the event of its intent to sell any shares of the stock, it shall
first offer these shares to GreenMan Technologies.  The price of the block shall
be that price which a bona fide third party  purchaser is, or will be willing to
pay for the block of shares  Lessor  wishes to sell.  If GreenMan  elects not to
purchase the block of shares  within  fifteen (15) days,  Optionee may then sell
the  block  to the  third  party  bona  fide  purchaser  on the same  terms  and
conditions offered by Lessor to GreenMan.

         Rent  unpaid  when due  shall  bear  interest  at the rate of  eighteen
percent (18%) per year.

                                  SECTION FOUR
                              LOCATION OF PROPERTY

         The  property  leased  under  this  agreement  shall  be  kept  at 4664
Princeville Road, City of St. Francisville,  Parish of West Feliciana,  State of
Louisiana.  It shall not be removed from that location without the prior written
consent of Lessor, which consent shall not be withheld unreasonably.

                                  SECTION FIVE
                              OWNERSHIP OF PROPERTY

                                  SECTION SEVEN
                            LESSOR'S RIGHT TO INSPECT

         Lessor shall have the right at any time during normal business hours to
enter on the  premises  where the leased  property is located for the purpose of
inspecting it or observing its use, maintenance, and operation,  provided Lessor
provides 24 hour notice of intent to inspect to Lessee.

                                  SECTION EIGHT
                       LESSEE'S INSPECTION AND ACCEPTANCE

         Lessee  acknowledges  that it has  inspected  every  item  of  property
delivered pursuant to this lease, that they are in good condition or a condition
otherwise  acceptable  to Lessee,  and that Lessee has accepted such property in
its present condition.  It is agreed that the property is being leased on an "as

                               RETURN OF PROPERTY

use  excepted,  to Prosperity  Road,  City of St.  Francisville,  Parish of West
Feliciana,  State of  Louisiana.  Should  Lessee  for any reason be unable to so
return the leased  property or any portion  thereof to Lessor,  Lessee shall pay
Lessor as liquidated damages an amount equal to the option price of the property
shown on the attached Schedule "C", subject to any reduction in the option price
by virtue of Section 23 infra.

                                   SECTION TEN
                                   WARRANTIES

         Lessor does not make any warranties,  express or implied, nor shall any
warranties  arise by  operation  of law, as to the  property  leased,  including
fitness  for  any  particular  use,   merchantability,   design,   capacity,  or
performance.

         Warranties  made by the seller or  manufacturer  of the leased property
are assigned by Lessor to Lessee for the term of this lease. In the event of any
claim  concerning  the  location,  installation,  repair or use of the  property
leased  or any other  claim  concerning  the  property,  regardless  of cause of
consequence,  Lessee's  only  remedy,  if any,  shall be  against  the seller or
manufacturer of the property. No defect, regardless of the cause or consequence,
shall  relieve  Lessee from  performing  its  obligation  under this  agreement,
including the payment of rentals.

                                 SECTION ELEVEN
                        STATUS OF PROPERTY AS PERSONALTY

         The  property  leased  under this  agreement  is, and will at all times
remain, movable property, notwithstanding that such property or any part may now
be, or may become,  attached to, or  permanently  rest on,  immovable  property.
Lessee agrees to obtain and keep in full force and effect for benefit of Lessor,
a waiver of  landlord's  lien from the owner(s) of any  immovable  property upon
which the property lease is located.

                                 SECTION TWELVE
                      USE, CARE, AND OPERATION OF PROPERTY

         Lessee shall use the property in a careful and proper manner, and shall
comply with all laws and regulations  prescribed by  governmental  authority and
with the seller's or  manufacturer's  instructions  relating to the  possession,
use, maintenance,  repair and operation of the property. The cost of maintenance
and  repair  shall  be the  sole  responsibility  of  Lessee  without  right  of
reimbursement from Lessor.  Lessee shall keep a log book showing,  at a minimum,
the type of maintenance,  repair,  or replacement work performed,  the date, the
cost, and the person ro entity performing the work. All replacement parts to any

         1. Lessee assumes all risks of loss of or damage to the leased property
from any cause. No loss of or damage to the property shall impair any obligation
of Lessee  under this Lease,  including  the  payment of  rentals,  and all such
obligations shall continue in full force and effect until otherwise discharged.

         2. In the event of loss or damage to the leased property, the following
shall apply:

         (a) If, in Lessor's judgment,  the property is properly and permanently
lost or damaged beyond repair so as to be unusable for the purpose for which the
property is intended,  and if Lessor is  indemnified to the extent of the agreed
insurable value specified in the attached  Schedule "B" for that particular item
of property,  the lease shall  terminate with respect to such  property.  If the
property is not insured, or the insurance is not collectible, or the property is
lost or destroyed by a peril not insured against, then, at the option of Lessor,
Lessee shall either  replace the property with like property in good  condition,
which property shall become the property of Lessor and subject to this lease, or
pay Lessor the agreed on insurance valuation of the property as specified in the
attached  Schedule  "B",  and on payment,  Lessee shall become the owner of such
property, and the lease with respect to such property shall be terminated.

         (b) In the event the loss or damage to any of the  leased  property  is
capable of being replaced or repaired,  and if Lessor shall be indemnified in an
amount less than the agreed on  insurance  valuation  specified  in the attached
schedule, Lessor shall have the option of repairing or replacing the property at
Lessee's  cost,  and the  proceeds of any  insurance  recovered,  including  the
portion  applicable  to  Lessor's  interest,  shall be applied in paying for the
costs of repair or replacement.  If no insurance is maintained by Lessee,  or if
such insurance is  uncollectible,  or if the damage or loss is caused by a peril
not insured  against,  Lessee  shall be  responsible  for the costs of repair or
replacement.  This  lease  shall  continue  uninterrupted  after  such  loss  or
destruction until the lease is otherwise terminated.

might be liable.

against all such liability, to the fullest extent allowed by law.

person and $3,000,000.00 Dollars per accident.

         3. Third party property damage  insurance in an amount of not less than
$1,000,000.00.

         Lessee shall cause Lessor to be named as an additional  insured, to the

when due,  Lessor may, but is under no obligation  to, pay the premiums.  Lessee
shall  within  five (5) days  from  notice  the  Lessor  has paid the  premiums,
reimburse Lessor for such payment.  If Lessee fails to reimburse Lessor for such
premiums with the period  provided,  the amount of  unreimbursed  premiums shall

         Lessee shall pay all taxes,  assessments,  licenses,  and  registration
fees that may now or hereafter be imposed on the ownership, leasing, possession,
or use of the leased property.  Lessee shall furnish Lessor  satisfactory  proof
that such  payment has been made before  such  taxes,  assessments,  license and
registration fees become  delinquent.  If Lessee fails to pay the charges before
the  delinquency  date,  Lessor may, but is not obligated  to, pay them.  Lessee
shall  reimburse  Lessor for any such payment  within five (5) days from written
notice of payment from Lessor.  Any such amounts that remain  unreimbursed shall
bear interest at the rate of eighteen percent (18%) per year.

                                SECTION SEVENTEEN

                               SECTION TWENTY-TWO
                                   TERMINATION

         Lessee,  if  not in  default  in any  of  its  obligations  under  this
agreement, may terminate this lease with respect to any or all items or property
leased at any time after  sixty (60)  months  from the date of  delivery of such
property,  by giving sixty (60) days written  notice of  termination  to Lessor.
Lessor, at its option, within sixty (60) days after return of such property, may
sell the property at public or private sale for the highest cash offer made. If,
after  deducting all costs and expenses in connection with the storage and sale,
the  aggregate  net  proceeds  from such sale  exceeds the option  price of such
property as  stipulated in the attached  Schedule  "C",  Lessor shall pay Lessee
fifty  percent  (50%) of the  excess.  If,  after  making such  deductions,  the
aggregate  net proceeds are less than the specified  option price,  Lessee shall
pay to Lessor the amount of the difference,  on written demand from Lessor. Such
amount shall bear interest at the rate of eighteen  percent (18%) per annum from
the date of demand.

                              SECTION TWENTY-THREE

         Lessee,  if not in default in any of its obligations  under this lease,
shall have an option to purchase any or all items of property leased at any time
after sixty (60) months from the date hereto.

         In the event Lessee exercises this option, eighty-five percent (85%) of
the sum  paid as base  rent  shall  be  applied  to the  purchase  price  of the
property.  On payment by Lessee to Lessor of the balance of the option price for
such  property as is specified in the Schedule "C" attached to this lease,  plus
any  applicable  unpaid sales of use taxes,  Lessor will  transfer  title of the
Leased  property to Lessee,  and this lease will  terminate with respect to such
property.

                               SECTION TWENTY-FOUR
                       ASSIGNMENT OR SUBLETTING BY LESSEE

its  rights  under  this lease or any of the  property  subject  of this  lease,

         Lessee  shall not lend or allow the  property  leased to be used by any
person  other than  Lessee's  employees,  without the prior  written  consent of
Lessor.

         Lessor may assign this lease or any of its rights under this  agreement
to anyone  other than a direct  competitor  of Lessee  without  prior  notice to
Lessee and without obtaining  Lessee's  consent.  In the event Lessor intends to
assign this lease to a competitor of Lessee,  written  consent to the assignment
must be obtained by Lessee. This consent may not be unreasonably  withheld.  Any
such  assignee  shall have all the rights and  obligations  of Lessor under this
lease.  However,  Lessor  shall  not  be  relieved  from  performing  any of its
obligations and  responsibilities  under this lease in the event its assignee is
unable to do so.

                               SECTION TWENTY-FIVE
                                     WAIVER

         No delay or omission to exercise  any right of Lessor  under this lease
shall be construed as a waiver of any such right or as impairing any such right.
Any waiver by Lessor of a single  breach or default  shall not be construed as a
waiver of any prior or subsequent breach or default.

                               SECTION TWENTY-SIX
                               CREDIT INFORMATION

         Lessee  certifies  that the  statements,  trade  references,  and other
documents  submitted  to  Lessor in  connection  with  this  lease are  material
inducements  to the  granting of this lease and any  material  misrepresentation
shall constitute a default under this agreement.

                              SECTION TWENTY-SEVEN
                   PLACE OF GIVING NOTICES AND MAKING PAYMENTS

                  THIS SECURITIES  PURCHASE  AGREEMENT,  dated as of the date of
acceptance   set  forth  below,   is  entered  into  by  and  between   GreenMan
Technologies,  Inc,  a  Delaware  corporation,  with  headquarters  located at 7

                              W I T N E S S E T H:

                  WHEREAS,   the  Company  and  the  Buyer  are   executing  and
delivering  this Agreement in reliance upon certain  exemptions  from securities
registration  afforded,  inter alia, by Rule 506 under Regulation D ("Regulation
D") as promulgated by the United States Securities and Exchange  Commission (the
"SEC") under the  Securities  Act of 1933,  as amended (the "1933 Act"),  and/or
Section 4(2) of the 1933 Act; and

                  WHEREAS,  the  Buyer  wishes to  purchase,  upon the terms and
subject to the  conditions of this  Agreement,  8% Convertible  Debentures  (the
"Debentures"),  of the Company which will be  convertible  into shares of Common
Stock,  $.01 par value per share (the "Common  Stock"),  of the Company upon the
terms and subject to the conditions of such Debentures (the Common Stock and the
Debentures  sometimes  referred to herein as the  "Securities"),  and subject to
acceptance of this Agreement by the Company.

                  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 parties agree as

                  1.       AGREEMENT TO PURCHASE; PURCHASE PRICE.

                  a. Purchase.  The  undersigned  hereby agrees to purchase from
the  Company  up to  $_________  in  principal  amount of  Debentures,  $_______

specifically set forth in P. 4(i) hereof.  The purchase price for each Debenture
shall be 100% of the principal  amount of such Debenture (the "Purchase  Price")
and shall be payable in United States Dollars. The Debentures offered hereby are
part of an  aggregate  offering  of up to  $3,600,000  in  principal  amount  of
Debentures,  including  $1,600,000  principal  amount at the First Closing.  The
Debentures shall be substantially in the form attacged hereto as Annex I. In the
event that any buyer in the offering does not fulfill its obligation to purchase
Additional  Debentures (as defined in P. 4(j) hereof), then the Buyer shall have
the right, but not the obligation to purchase such Additional Debentures.

                  b. Form of Payment. The Buyer shall pay the Purchase Price for
each Debenture by delivering  immediately  available good funds in United States
Dollars to the escrow agent (the "Escrow Agent")  identified in the Joint Escrow

set forth below.  Promptly following payment by the Buyer to the Escrow Agent of
the Purchase  Price of the  Debenture,  the Company  shall deliver the Debenture
duly  executed on behalf of the  Company to the Escrow  Agent.  By signing  this
Agreement, the

                  c. Method of  Payment.  Payment  into  escrow of the  Purchase
Price for each Debenture shall be made by wire transfer of funds to:

                  2.  BUYER REPRESENTATIONS, WARRANTIES, ETC.; ACCESS TO
INFORMATION; INDEPENDENT INVESTIGATION.

                  The Buyer represents and warrants to, and covenants and agrees
with, the Company as follows:

                  a.  Without  limiting  Buyer's  right to sell the Common Stock
pursuant to the  Registration  Statement as defined in the  Registration  Rights
Agreement,  the Buyer is  purchasing  the  Debentures  and will be acquiring the
shares of Common Stock  issuable upon  conversion of the  Debentures for its own
account  for  investment  only and not with a view  towards  the public  sale or
distribution  thereof and not with a view to or for sale in connection  with any
distribution thereof;

                  b. The Buyer is (i) an  "accredited  investor" as that term is
defined in Rule 501 of the General Rules and  Regulations  under the 1933 Act by
reason of Rule 501(a)(3), and (ii) experienced in making investments of the kind
described in this Agreement and the related documents,  (iii) able, by reason of
the  business  and  financial  experience  of its  officers  (if an entity)  and
professional  advisors (who are not affiliated with or compensated in any way by
the Company

                                       -2-

<PAGE>



or any of its  affiliates  or selling  agents),  to protect its own interests in
connection with the  transactions  described in this Agreement,  and the related
documents,  and (iv) able to afford the  entire  loss of its  investment  in the
Securities;

                  c. All  subsequent  offers and sales of the Debentures and the
shares of Common Stock  issuable upon  conversion  of, or issued as interest on,
the  Debentures  (the  "Shares"  or  "Common  Stock"  and,   together  with  the
Debentures,   the   "Securities")  by  the  Buyer  shall  be  made  pursuant  to
registration  of the Shares under the 1933 Act or pursuant to an exemption  from
registration;

                  d. The Buyer understands that the Debentures are being offered
and sold,  and the Shares  are being  offered,  to it in  reliance  on  specific
exemptions from the registration requirements of United States federal and state
securities  laws and that the Company is relying upon the truth and accuracy of,
and the Buyer's compliance with, the  representations,  warranties,  agreements,
acknowledgments  and  understandings  of the Buyer set forth  herein in order to
determine the  availability  of such exemptions and the eligibility of the Buyer
to acquire the Debentures and to receive an offer of the Shares, and Buyer shall
indemnify and hold harmless the Company from and against any liability  incurred
by the Company proximately caused by any breach thereof by Buyer;

                  e. The Buyer and its  advisors,  if any,  have been  furnished
with all  materials  relating to the  business,  finances and  operations of the
Company and materials  relating to the offer and sale of the  Debentures and the
offer of the Shares which have been requested by the Buyer,  including  Annex VI
hereto.  The Buyer and its advisors,  if any, have been afforded the opportunity
to ask  questions of the Company and have  received  complete  and  satisfactory
answers to any such inquiries. Without limiting the generality of the foregoing,
the Buyer has also had the opportunity to obtain and to review the Company's (1)
Annual Report on Form 10-KSB for the fiscal year ended May 31, 1997, as amended,
(2)  Quarterly  Report on Form 10-QSB for the fiscal  quarter  ended  August 31,
1997,  and (3)  Registration  Statement  on Form S-3 (file No.  333-27625)  (the
"Company's SEC Documents");

                  f. The Buyer understands that its investment in the Securities
involves a high degree of risk;

                  g. The Buyer  understands  that no United  States  federal  or
state agency or any other  government  or  governmental  agency has passed on or
made any recommendation or endorsement of the Securities;

                  h.  This  Agreement  has  been  duly and  validly  authorized,
executed  and  delivered  on behalf  of the  Buyer  and is a valid  and  binding
agreement of the Buyer  enforceable in accordance with its terms,  subject as to
enforceability  to general  principles of equity and to bankruptcy,  insolvency,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally;

  
                                       -3-

<PAGE>


                  i. Neither  Buyer,  nor any  affiliate  of Buyer,  shall enter
into, any put option, short position,  or other similar position with respect to
the Debentures or the Shares; provided, however, that the foregoing shall not in
any manner  restrict the Buyer from  selling any Shares  simultaneous  with,  or
following the delivery of a Conversion Notice.

                  j. Notwithstanding the provisions hereof or of the Debentures,
in no event, other than the automatic  conversion of the outstanding amount of a
Debenture at maturity,  shall the holder be entitled to convert any Debenture to
the extent after such conversion,  the sum of (1) the number of shares of Common
Stock  beneficially  owned by the Buyer and its affiliates (other than shares of
Common Stock which may be deemed beneficially owned through the ownership of the
unconverted  portion of the  Debenture),  and (2) the number of shares of Common
Stock  issuable upon the  conversion of the Debenture  with respect to which the
determination  of this  proviso  is  being  made,  would  result  in  beneficial
ownership by the Buyer and its  affiliates of more than 4.9% of the  outstanding
shares of Common Stock. For purposes of the proviso to the immediately preceding
sentence,  beneficial  ownership  shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended,  and Regulation 13 D-G
thereunder, except as otherwise provided in clause (1) of such proviso.

                  3.       COMPANY REPRESENTATIONS, ETC.

                  The Company represents and warrants to the Buyer that:

                  a.  Concerning the Shares.  There are no preemptive  rights of
any stockholder of the Company, as such, to acquire the Common Shares;

                  b. Reporting Company Status. The Company is a corporation duly
organized,  validly existing and in good standing under the laws of the State of

the Securities  Exchange Act of 1934, as amended (the "Exchange  Act"),  and the
Common  Stock is listed and traded on the  NASDAQ/Small  Cap.  The  Company  has
received  no notice,  either  oral or  written,  with  respect to the  continued
eligibility of the Common Stock for such listing;

                  c. Authorized  Shares.  The Company has sufficient  authorized
and unissued  Shares as may be reasonably  necessary to effect the conversion of
the  Debentures.  The Shares  have been duly  authorized  and,  when issued upon
conversion  of, or as  interest  on, the  Debentures,  will be duly and  validly
issued, fully paid and non-assessable and will not subject the holder thereof to
personal liability by reason of being such holder;

                  d.  Securities   Purchase   Agreement;   Registration   Rights
Agreement and Stock. This Agreement and the Registration  Rights Agreement,  the
form  of  which  is  attached  hereto  as  Annex  IV (the  "Registration  Rights
Agreement"),  and the  transactions  contemplated  thereby,  have  been duly and
validly  authorized  by the Company,  this  Agreement has been duly executed and
delivered  by the Company and this  Agreement  is, and the  Registration  Rights
Agreement,  when  executed  and  delivered  by the  Company,  will be, valid and
binding  agreements  of  the  Company   enforceable  in  accordance  with  their
respective terms,  subject as to enforceability to general  principles of equity
and to bankruptcy, insolvency, moratorium, and other similar laws affecting the

                                       -4-

<PAGE>



enforcement of creditors' rights  generally;  and the Debenture will be duly and
validly  authorized and, when executed and delivered on behalf of the Company in
accordance  with this Agreement,  will be a valid and binding  obligation of the
Company in accordance  with its terms,  subject to general  principles of equity
and to bankruptcy,  insolvency,  moratorium, or other similar laws affecting the
enforcement of creditors' rights generally;

                  e.  Non-contravention.  The  execution  and  delivery  of this
Agreement and the Registration Rights Agreement by the Company,  the issuance of
the Securities,  and the  consummation by the Company of the other  transactions
contemplated by this  Agreement,  the  Registration  Rights  Agreement,  and the
Debentures  do not and will  not  conflict  with or  result  in a breach  by the
Company of any of the terms or provisions  of, or constitute a default under (i)
the articles of  incorporation  or by-laws of the Company,  (ii) any  indenture,
mortgage,  deed of trust, or other material agreement or instrument to which the
Company is a party or by which it or any of its  properties or assets are bound,
including any listing agreement for the Common Stock except as herein set forth,
(iii) any existing applicable law, rule, or regulation or any applicable decree,
judgment,  or (iv) order of any court, United States federal or state regulatory
body, administrative agency, or other governmental body having jurisdiction over
the Company or any of its properties or assets, except such conflict,  breach or
default  which  would not have a  material  adverse  effect on the  transactions
contemplated herein;

                  f.  Approvals.  No  authorization,  approval or consent of any
court, governmental body, regulatory agency, self-regulatory organization, or of
any stock exchange or market or the  stockholders  of the Company is required to
be obtained by the Company for the  issuance and sale of the  Securities  to the
Buyer as contemplated by this Agreement,  except such authorizations,  approvals
and consents that have been obtained;

                  g. SEC Filings.  None of the SEC Filings  with the  Securities
and  Exchange  Commission  since June 1, 1996  contained,  at the time they were
filed,  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  made
therein  in  light  of  the  circumstances  under  which  they  were  made,  not
misleading. The Company has since June 1, 1996 timely filed all requisite forms,
reports and exhibits thereto with the Securities and Exchange Commission;

                  h. Absence of Certain  Changes.  Since June 1, 1997, there has
been no material  adverse  change and no  material  adverse  development  in the
business, properties,  operations, financial condition, or results of operations
of the Company,  except as disclosed in Annex VI or in the documents referred to
in Section 2(e) hereof;

                  i.  Full  Disclosure.  There is no fact  known to the  Company
(other than general  economic  conditions  known to the public  generally) or as
disclosed  in the  documents  referred  to in  Section  2(e),  that has not been
disclosed in writing to the Buyer that (i) could  reasonably be expected to have
a material  adverse  effect on the condition  (financial or otherwise) or in the
earnings,  business  affairs,  properties or assets of the Company or (ii) could
reasonably  be expected to materially  and  adversely  affect the ability of the
Company to perform its obligations pursuant to this Agreement;

                                       -5-

                  j.  Absence  of  Litigation.  Except  as set forth in Annex VI
hereto,  and in the documents  referred to in Section 2(e),  which the Buyer has
reviewed, there is no action, suit, proceeding,  inquiry or investigation before
or by any  court,  public  board or body  pending  or, to the  knowledge  of the
Company or any of its subsidiaries,  threatened against or affecting the Company
or any of its subsidiaries,  wherein an unfavorable decision,  ruling or finding
would have a material  adverse  effect on the  properties,  business,  condition
(financial or other),  results of operations or prospects of the Company and its
subsidiaries taken as a whole or the transactions contemplated by this Agreement
or any of the documents  contemplated hereby or which would adversely affect the
validity or  enforceability  of, or the  authority  or ability of the Company to
perform its obligations under, this Agreement or any of such other documents;

                  k. Absence of Events of Default.  Except as set forth in Annex
VI hereto, no Event of Default, as defined in the respective  agreement to which
the  Company is a party,  and no event  which,  with the giving of notice or the
passage of time or both,  would become an Event of Default (as so defined),  has
occurred and is  continuing,  which would have a material  adverse effect on the
Company's financial condition or results of operations;

                  l. No Default. Except as set forth on Annex VI, the Company is
not in default in the  performance  or  observance  of any material  obligation,
agreement,  covenant or condition contained in any indenture,  mortgage, deed of
trust or other  material  instrument  or  agreement to which it is a party or by
which it or its property is bound,  and neither the execution,  nor the delivery
by the Company, nor the performance by the Company of its obligations under this
Agreement or the Debentures,  other than the conversion provision thereof,  will
conflict  with or  result  in the  breach  or  violation  of any of the terms or
provisions  of, or  constitute a default or result in the creation or imposition
of any lien or charge on any assets or  properties  of the  Company  under,  any
material  indenture,  mortgage,  deed  of  trust  or  other  material  agreement
applicable  to the Company or  instrument  to which the Company is a party or by
which it is bound or any statute or the Articles of  Incorporation or By-Laws of

                  4.       CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

                  a. Transfer Restrictions.  The Buyer acknowledges that (1) the
Debentures  have not been and are not being  registered  under the provisions of
the 1933 Act and, except as provided in the Registration  Rights Agreement,  the
Shares have not been and are not being  registered  under the 1933 Act,  and may
not be  transferred  unless (A)  subsequently  registered  thereunder or (B) the
Buyer shall have  delivered  to the  Company an opinion of  counsel,  reasonably
satisfactory in form, scope and substance to the Company and its transfer agent,
to the  effect  that the  Securities  to be sold or  transferred  may be sold or
transferred pursuant to an exemption from such

                                       -6-

registration;  (2) any  sale of the  Securities  made in  reliance  on Rule  144
promulgated  under the 1933 Act may be made only in accordance with the terms of
said  Rule and  further,  if said  Rule is not  applicable,  any  resale of such
Securities under  circumstances in which the seller,  or the person through whom
the sale is made,  may be deemed to be an  underwriter,  as that term is used in
the 1933 Act, may require  compliance  with some other  exemption under the 1933
Act or the rules and  regulations  of the SEC  thereunder;  and (3)  neither the
Company nor any other person is under any  obligation to register the Securities
(other than pursuant to the Registration Rights Agreement) under the 1933 Act or
to comply with the terms and conditions of any exemption thereunder.

                  b. Restrictive  Legend. The Buyer acknowledges and agrees that
the  Debentures,  and,  until such time as the Common Stock has been  registered
under the 1933 Act as contemplated by the Registration Rights Agreement and sold
in  accordance  with such  Registration  Statement,  the shares of Common  Stock
issued to the Holder upon conversion of the Debentures  shall bear a restrictive
legend in  substantially  the following form (and a  stop-transfer  order may be
placed against transfer of the Debenture and such shares of Common Stock):

         NEITHER  THESE  SECURITIES  NOR THE  SECURITIES  ISSUABLE UPON EXERCISE
         HEREOF  HAVE BEEN  REGISTERED  WITH THE UNITED  STATES  SECURITIES  AND
         EXCHANGE  COMMISSION  OR THE  SECURITIES  COMMISSION  OF ANY  STATE  OR
         CANADIAN PROVINCE, OR UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
         "SECURITIES  ACT").  THE  SECURITIES  ARE  RESTRICTED  AND  MAY  NOT BE
         OFFERED,  RESOLD,  PLEDGED OR TRANSFERRED EXCEPT AS PERMITTED UNDER THE
         SECURITIES  ACT PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT OR AN
         EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS.


                  c. Registration Rights Agreement.  The parties hereto agree to
enter into the Registration Rights Agreement, in substantially the form attached
hereto as Annex IV, on or before the Initial Closing Date.

                  d.  Filings.  The  Company  undertakes  and agrees to make all
necessary  filings in  connection  with the sale of the  Debentures to the Buyer
under any United  States laws and  regulations,  or by any  domestic  securities
exchange or trading market,  and to provide a copy thereof to the Buyer promptly
after such filing.

                  e. Reporting  Status.  So long as the Buyer  beneficially owns
any of the Debentures,  the Company shall file all reports  required to be filed
with the SEC pursuant to Section 13 or 15(d) of the  Securities  Exchange Act of
1934,  as amended  (the "1934 Act"),  and the Company  shall not  terminate  its
status as an issuer required to file reports under the 1934 Act even if the 1934
Act or the rules and regulations thereunder would permit such termination.

                  f. Use of Proceeds. The Company will use the proceeds from the
sale of the Debentures (excluding amounts paid by the Company for legal fees and
finder's fees in connection

                                       -7-

                  g.  Certain  Agreements.  For a period of fifteen  (15) months

first refusal (together with any other purchasers in this offering to the extent
of their original  investment in this  financing) to purchase any debt or equity
securities  of the  Company  which  the  Company  intends  to offer in a private
placement transaction for cash proceeds. However, this provision shall not apply
to (x) the issuance of  securities  (other than for cash) in  connection  with a
merger,  consolidation,  sale of  assets,  disposition  of a  business,  sale of
products  or  granting  of a license by the  Company in the  ordinary  course of
business, strategic alliance, bank loan or agreement,  compensation to employees
or  consultants,  the  exercise  of  outstanding  options and  warrants,  or the
conversion of any outstanding  covertible  securities or (y) the exchange of the
capital stock for assets,  stock,  partnership,  limited liability  company,  or
other joint venture interests.

                  h.  Available  Shares.  The  Company  shall  have at all times
authorized and reserved for issuance,  free from  preemptive  rights,  shares of
Common  Stock  sufficient  to yield  the  number  of Common  Stock  issuable  at
conversion  as may be  required to satisfy  the  conversion  rights of the Buyer
pursuant to the terms and conditions of the Debentures.

                  i.  Warrants.  The  Company  agrees  to  issue to Buyer at the
Closing,  transferable  divisible warrants (the "Warrants") for ______ shares of
Common  Stock.  Such Warrants  shall bear an exercise  price per share of Common
Stock as follows: 110% of the Market Price, as defined in the Debenture,  on the
Closing Date, and shall be exercisable two (2) business days following issuance,
and for a period  of two (2) years  thereafter,  in the form  annexed  hereto as
Annex V, and the shares of Common Stock  issuable  upon  exercise of the Warrant
shallbe registered in accordance with the Registration  Rights Agreement annexed
hereto as Annex IV. At each date on which  Additional  Debentures (as defined in
P. 4(j) below) are issued (each an "Additional Closing Date"), the Company shall
issue to the Buyer at each such closing, additional Warrants (as defined in this
P. 4(i)) at the rate of one Warrant for the purchase of 100,000 shares of Common
Stock for each $1 million of Additional Debentures  purchased,  or pro rated for
any portion thereof.

                  j.  The  Buyer  irrevocably   agrees  to  purchase  up  to  an
additional  $_______ of Debentures (the "Additional  Debentures") in a series of
tranches,   commencing  thirty  (30)  days  after  the  effective  date  of  the
registration   statement  contemplated  by  the  Registration  Rights  Agreement
attached  hereto  as  Annex IV (the  "Effective  Date")  and  ending  12  months
following  the  Effective   Date,   upon  the  same  terms  and  conditions  and
substantially in the form as those applicable to the initial  Debentures  issued
pursuant to the  Agreement  except as set forth in 4(j)(d) and the maturity date
of such Additional  Debenture shall be December 15, 2000.  Buyer's obligation to

occur not less  than  thirty  (30) days  apart),  shall be  contingent  upon the
satisfaction of the following conditions:



                                       -8-

<PAGE>



                  (a) The  Company  shall  give the Buyer  seven (7) days  prior

                  (c) On each Additional Closing Date:

                      (i) the Registration  Statement required to be filed under
the Registration Rights Agreement, is effective;

                      (ii)  The  representations  and  warranties  contained  in
Section 3 shall be true and correct in all material respects;

                      (iii) The share value of the  Company's  Common Stock must
be $.60 or greater and the average daily trading volume of the Company's  Common
Stock for the previous three months must exceed 50,000 shares per day;

                      (iv) The dollar value of the average daily trading  volume
of the Company's Common Stock for the previous three months must exceed $600,000
per month;

                      (v) The number of shares  issuable upon  conversion of the
Debentures,  together  with the  Shares of Common  Stock  issued  prior  thereto
pursuant to this Agreement, will not exceed 20% of the outstanding Common Shares
of the Company.

                  (d)  The  conversion  price  for  shares  to  be  issued  upon
conversion  of the  Additional  Debentures  shall be 75% of the Market Price (as
defined  in  the   Debentures)  on  the  Conversion  Date  (as  defined  in  the
Debentures). The maximum conversion rate will be 100% of the average closing bid
price of the Common Stock on the five  consecutive  trading days  preceding  the
Additional Closing Date.

                  (e) In the event that the Company does not exercise its option
to require the Buyer to purchase at least  $1,219,000 of  Debentures  (including
the $750,000 at the First Closing), the Company will, not later than twelve (12)
months after the date hereof,  issue to the Buyer an additional  46,900 Warrants
upon the terms and  conditions  of P. 4i  hereof.  In any event,  the  Company's
obligations under the Registration  Rights  Agreement,  shall be to register the
necessary  Common Stock  underlying  $3,600,000  in  Debentures,  and the shares
underlying 360,000 Warrants to purchase Common Stock.

                  5.       TRANSFER AGENT INSTRUCTIONS.

                  a. The Company  will permit the Buyer to exercise its right to
convert  the  Debenture  and/or  exercise  the  Warrant,  as the case may be, by
telecopying an executed and completed  Notice of Conversion or Exercice  Notice,
as the case may be, in the  respective  forms  attached to the Form of Debenture
attached  hereto as Annex I and Form of Warrant  attached  hereto as Annex V, to
the Company and delivering within three business days thereafter, the original

                                       -9-

<PAGE>



Notice of Conversion and the Debenture  representing the Shares, or the original
Exercise  Notice and Warrant,  to the Company by express courier to the Transfer
Agent.  Each  date on  which a  Notice  of  Conversion  or  Exercise  Notice  is
telecopied  to and  received by the Company in  accordance  with the  provisions
hereof  shall be deemed a  Conversion  Date or exercise  date.  The Company will
transmit, or cause to be transmitted,  the certificates  representing the Shares
of Common Stock  issuable  upon  conversion of any  Debenture  (together  with a
replacement  Debenture  representing  any principal  amount not so converted) or
exercise of the Warrant  (together with a replacement  Warrant  representing any
portion not exercised) to the Buyer via express courier,  by electronic transfer
or otherwise, within three (3) business days after receipt by the Company or its
transfer  agent  of  the  original   Notice  of  Conversion  and  the  Debenture
representing  the Shares to be  converted or the  original  Exercise  Notice and
Warrant (the "Delivery Date").

                  b. In lieu of delivering physical certificate representing the
Common Stock  issuable upon  conversion of a Debenture or exercise of a Warrant,
provided the company's  transfer agent is  participating in the Depository Trust
Company ("DTC") Fast Automated Securities Transfer program,  upon request of the
Buyer and its compliance  with the provisions  contained in this  paragraph,  so
long as the  certificates  do not bear a legend  and the  Buyer  thereof  is not
obligated to return such certificate for the placement of a legend thereon,  the
Company shall use its best efforts to cause its transfer agent to electronically
transmit the Common Stock  issuable upon  conversion or exercise to the Buyer by
crediting  the  account of Buyer's  Prime  Broker  with DTC  through its Deposit
Withdrawal Agent Commission system.

                  c. The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date could result in economic loss to
the Buyer. As compensation to the Buyer for such loss, the Company agrees to pay
late  payments  to the Buyer for late  issuance  of Shares  upon  Conversion  in
accordance  with the  following  schedule  (where  "No.  Business  Days Late" is
defined as the number of  business  days  beyond  three (3)  business  days from

The Company shall pay any payments  incurred  under this Section in  immediately
available funds upon demand.  Nothing herein shall limit Buyer's right to pursue

to the  Buyer,  in the event  that the  Company  fails for any  reason to effect
delivery of such shares of Common  Stock  within  five  business  days after the
Delivery  Date,  the Buyer will be  entitled  to revoke the  relevant  Notice of
Conversion  by  delivering a notice to such effect to the Company  whereupon the
Company  and the Buyer  shall each be  restored  to their  respective  positions
immediately prior to delivery of such Notice of Conversion.

                          REGISTRATION RIGHTS AGREEMENT

         THIS  REGISTRATION  RIGHTS  AGREEMENT,  dated as of December  ___, 1997
(this  "Agreement"),  is made by and  between  GREENMAN  TECHNOLOGIES,  INC.,  a
Delaware corporation (the "Company"), and the person named on the signature page
hereto (the "Initial Investor").

                              W I T N E S S E T H:

         WHEREAS, upon the terms and subject to the conditions of the Securities
Purchase Agreement,  dated as of December __, 1997, between the Initial Investor
and the Company (the "Securities Purchase Agreement"), the Company has agreed to
issue and sell to the Initial Investor one or more 8% Convertible  Debentures of
the Company  (collectively  the  "Debentures"),  and  warrants to purchase up to
_______ shares of Common Stock which  Debentures will be convertible into shares
of the common stock,  $.01 par value (the "Common  Stock"),  of the Company (the
"Conversion  Shares")  upon the  terms and  subject  to the  conditions  of such
Debentures, and the Warrants will be exercisable for shares of Common Stock (the
"Warrant Shares"); and

         WHEREAS,  to induce the  Initial  Investor  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
"Securities Act"), with respect to the Conversion Shares and Warrant Shares;

         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 Investor hereby agrees as follows:

         1.       Definitions.

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

         "Investor" means the Initial  Investor and any permitted  transferee or
assignee  who agrees to become  bound by the  provisions  of this  Agreement  in
accordance with Section 9 hereof.

         "Register,"  "Registered," and  "Registration"  refer to a registration
effected by  preparing  and filing a  Registration  Statement or  Statements  in
compliance with the Securities Act and pursuant to Rule 415 under the Securities
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").

         "Registrable  Securities"  means the Conversion  Shares and the Warrant
Shares.

         "Registration  Statement" means a registration statement of the Company
under the Securities Act.

                                                       

<PAGE>



         As used in this Agreement, the term Investor includes (i) each Investor
(as  defined  above)  and (ii) each  person  who is a  permitted  transferee  or
assignee of the Registrable Securities pursuant to Section 9 of this Agreement.

         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 prepare and file with the
SEC, no later than fifteen (15) days  following  the initial  Closing Date under
the Securities Purchase Agreement,  either a Registration  Statement on Form S-3
registering  for resale by the Investor a sufficient  number of shares of Common
Stock for the Initial Investors (or such lesser number as may be required by the
SEC,  but in no event less than the number of shares  into which the  Debentures
would be convertible  and the Warrants  exercisable at the time of filing of the
Form S-3, or an amendment to any pending Company Registration  Statement on Form
S-3, and such  Registration  Statement or amended  Registration  Statement shall
state that, in  accordance  with Rule 416 and 457 under the  Securities  Act, it
also covers such  indeterminate  number of additional  shares of Common Stock as
may become  issuable upon  conversion of the  Debentures and the exercise of the
Warrants  resulting  from  adjustment  in the  Conversion  Price,  or to prevent
dilution  resulting from stock splits, or stock  dividends).  If at any time the
number of shares of Common  Stock into  which the  Debentures  may be  converted
exceeds the  aggregate  number of shares of Common  Stock then  registered,  the
Company  shall,  within ten (10) business days after receipt of a written notice
from any  Investor,  either (i) amend the  Registration  Statement  filed by the
Company pursuant to the preceding sentence,  if such Registration  Statement has
not been  declared  effective by the SEC at that time, to register all shares of
Common  Stock  into  which  the  Debenture  may be  converted,  or  (ii) if such
Registration Statement has been declared effective by the SEC at that time, file
with the SEC an  additional  Registration  Statement on Form S-3 to register the
shares of Common Stock into which the Debenture may be converted that exceed the
aggregate number of shares of Common Stock already  registered.  If the staff of
the SEC determines that all of the Conversion Shares cannot be registered by the
Company  for resale by the  Investor  because,  in the view of the  staff,  such
registration  would  constitute  a primary  offering  by the  Company,  then the
Company  shall  have an  additional  sixty  (60)  days in which  to  amend  such
registration statement to another available form.

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

                                       -2-

<PAGE>



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  Debentures  held by such
Investors  (including,  without limitation,  Debentures that have been converted
into  Conversion  Shares  then held by such  Investors)  (the  "Aggregate  Share
Price") multiplied by three hundredths (.03) 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 $30,000 for
each  $1,000,000 of Aggregate  Share Price and would continue to pay $30,000 per
month 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 Debenture),  may be convertible into Common Stock at the "Conversion  Price"
(as defined in the Debenture). Any shares of Common Stock issued upon conversion
of such amounts  shall be  Registrable  Securities.  If the Investor  desires to
convert the amounts due hereunder into Registrable Securities it shall so notify
the Company in writing  within two (2)  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  Debenture),  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,
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
Debenture.  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 Debenture Shares,  and valued at
the Conversion Rate, as such term is defined in Section 4 of the Debenture.

         (c)      Late Filing Payments by the Company.

         If the Registration  Statement  covering the Registrable  Securities is
not filed in proper form with the  Securities  and  Exchange  Commission  within
twenty five (25) days after the  Closing,  the Company  will make payment to the
Initial  Investor  in the amount of $500 per day for each  $10,000 in  principal
amount of Debentures for each day thereafter until such Registration  Statement,
in proper form, is filed with the Securities and Exchange Commission.

         3.  Obligations of the Company.  In connection with the registration of
the Registrable Securities, the Company shall do each of the following.

                                       -3-

<PAGE>


         (a) Prepare promptly,  and file with the SEC by fifteen (15) days after
the initial Closing Date, a Registration Statement with respect to not less than
the number of  Registrable  Securities  provided  in Section  2(a),  above,  and
thereafter use its best efforts to cause each Registration Statement relating to
Registrable Securities to become effective on the earlier of (i) five days after
notice  from the  Securities  and  Exchange  Commission  that  the  Registration
Statement  may be declared  effective,  or (b) sixty (60) days after the Closing
Date,  and keep the  Registration  Statement  effective  at all times  until the
earliest (the "Registration Period") of (i) the date that is two years after the
Closing  Date  (ii)  the  date  when the  Investors  may  sell  all  Registrable
Securities under Rule 144 without  restriction,  or (iii) the date the Investors
no longer own any of the Registrable  Securities,  which Registration  Statement
(including  any  amendments or supplements  thereto and  prospectuses  contained
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,  in light of the circumstances in which they were made, not
misleading;

         (b)  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   effective  at  all  times  during  the
Registration  Period,  and,  during the  Registration  Period,  comply  with the
provisions  of  the  Securities  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;

         (c) 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.

         (d) Furnish to each Investor whose Registrable  Securities are included
in the Registration  Statement and its legal counsel  identified to the Company,
(i) promptly after the same is prepared and publicly distributed, filed with the
SEC, or received by the  Company,  one (1) copy of the  Registration  Statement,
each  preliminary  prospectus and  prospectus,  and each amendment or supplement
thereto, and (ii) such number of copies of a 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;

         (e) As promptly as practicable  after becoming aware of such event, and
in no event later than two (2) business days after becoming aware of such event,
notify  each  Investor  of the  happening  of any event of which the 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
omits 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,  and use its best efforts promptly to prepare a supplement
or amendment to the Registration  Statement or other appropriate filing with the
SEC to correct such untrue statement or omission, and deliver a number of copies
of such supplement or amendment to each Investor as such Investor may reasonably
request;

                                       -4-

<PAGE>



         (f) As promptly as practicable  after becoming aware of such event, and
in no event later than two (2) business days after becoming aware of such event,
notify each Investor who holds Registrable Securities being sold of the issuance
by the SEC of a Notice of  Effectiveness  or any notice of  effectiveness or any
stop  order  or  other  suspension  of the  effectiveness  of  the  Registration
Statement at the earliest possible time;

         (g) Use its commercially  reasonable  efforts to secure  designation of
all the  Registrable  Securities  covered  by the  Registration  Statement  as a
National   Association  of  Securities   Dealers  Automated   Quotations  System
("NASDAQ") "Small  Capitalization" within the meaning of Rule 11Aa2-1 of the SEC
under the Securities  Exchange Act of 1934, as amended (the "Exchange Act"), and
the quotation of the Registrable  Securities on the NASDAQ Small Cap Market;  or
if,  despite  the  Company's  commercially  reasonable  efforts to  satisfy  the
preceding clause,  the Company is unsuccessful in doing so, to secure NASDAQ/OTC
Bulletin Board authorization and quotation for such Registrable  Securities and,
without  limiting the generality of the  foregoing,  to arrange for at least two
market makers to register with the National  Association of Securities  Dealers,
Inc. ("NASD") as such with respect to such Registrable Securities;

         (h)  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;

         (i) Cooperate with the Investors who hold Registrable  Securities being
offered to facilitate the timely  preparation and delivery of  certificates  for
the Registrable  Securities to be offered pursuant to the Registration Statement
and  enable  such  certificates  for the  Registrable  Securities  to be in such
denominations  or amounts as the case may be, as the  Investors  may  reasonably
request,  and,  within three (3) business  days after a  Registration  Statement
which  includes  Registrable  Securities  is ordered  effective  by the SEC, the
Company shall deliver,  and shall cause legal counsel selected by the Company to
deliver,  to the transfer agent for the Registrable  Securities  (with copies to
the Investors  whose  Registrable  Securities are included in such  Registration
Statement) an appropriate instruction and opinion of such counsel;

         (j) Take  all  other  reasonable  actions  necessary  to  expedite  and
facilitate disposition by the Investor of the Registrable Securities pursuant to
the Registration Statement;

         (k) Use  its  best  efforts  to  qualify  the  sale of the  Registrable
Securities  for sale in such  states  as the  Investor  actually  maintains  its
principal  residence,  provided,  however,  the Company shall not be required to
qualify  in any state  where it would be  required  to  register  as a broker or
dealer or where the state would require an escrow or other similar  restrictions
to upon the Company, any of its shareholders or the Investor; and

         (l) The Company shall not be obligated to take any action to effect any
such  registration,  qualification or compliance  pursuant to this  Registration
Rights  Agreement or to pay any amount for failure to do so if the Company would
be  required  to  provide  audited  financial  statements  in  the  Registration
Statement for a period other than the end of its fiscal year, in which event the
Company's  obligation  to  register,  qualify  or  comply  with  the  provisions
requiring it to cause the  Registration  Statement to become  effective shall be
deferred  for a period not to exceed  the  shorter  of: (i) the time  reasonably
required to obtain  audited  financial  statements  for the period ending on the
last day of its fiscal year, and to include them in the  Registration  Statement
or an amendment

                                       -5-

<PAGE>



thereto, or (ii) 120 days from the date required for such Registration Statement
to become effective pursuant to this Registration Rights Agreement.

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

         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. At least five (5) days prior
to the first anticipated filing date of the Registration Statement,  the Company
shall notify each  Investor of the  information  the Company  requires from each
such Investor (the "Requested  Information") if such Investor elects to have any
of  such  Investor's   Registrable   Securities  included  in  the  Registration
Statement.  If at least  two (2)  business  days  prior to the  filing  date the
Company  has  not  received  the  Requested  Information  from  an  Investor  (a
"Non-Responsive Investor"), then the Company may file the Registration Statement
without including Registrable Securities of such Non-Responsive Investor;

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

         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),
above,  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.  No
Investor  shall have any right to seek or obtain an  injunction  or  restraining
order, or otherwise delay any such registration as a result of any controversies
that might arise with respect to the interpretation of this Agreement.

         5.  Expenses  of  Registration.  All  reasonable  expenses,  other than
underwriting   discounts   and   commissions   incurred   in   connection   with
registrations,  filings or qualifications  pursuant to Section 3, but including,
without limitation, all registration, listing, and qualifications fees, printers
and  accounting  fees,  the fees and  disbursements  of counsel for the Company,
shall be borne by the Company.  The Investors  shall be responsible for the fees
and expenses of their respective counsels.

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

                                       -6-

<PAGE>




         To the extent  permitted by law, the Company  will  indemnify  and hold
harmless each Investor who holds such Registrable Securities,  the directors, if
any, of such Investor,  the officers, if any, of such Investor,  each person, if
any, who controls any Investor  within the meaning of the  Securities Act or the
Exchange  Act (each,  an  "Indemnified  Person"),  against any  losses,  claims,
damages,  liabilities  or expenses  (joint or several)  incurred  (collectively,
"Claims") to which any of them may become subject under the Securities  Act, the
Exchange Act or  otherwise,  insofar as such Claims (or actions or  proceedings,
whether  commenced or threatened,  in respect thereof) arise out of or are based
upon  any  of  the  following   statements,   omissions  or  violations  in  the
Registration  Statement,  or  any  post-effective   amendment  thereof,  or  any
prospectus  included  therein:  (i)  any  untrue  statement  or  alleged  untrue
statement  of a material  fact  contained in the  Registration  Statement or any
post-effective  amendment  thereof or 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,  (ii) any untrue statement or alleged untrue
statement of a material fact  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 Securities  Act,
the Exchange Act, any state  securities law or any rule or regulation  under the
Securities Act, the Exchange Act or any state securities law (the matters in the
foregoing  clauses (i) through  (iii) being,  collectively,  "Violations").  The
Company shall  reimburse the  Investors,  promptly as such expenses are incurred
and  are due and  payable,  for any  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) shall not (I) 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 or on behalf of any
Indemnified  Person  expressly for use in connection with the preparation of the
Registration  Statement or any such amendment thereof or supplement  thereto, if
such  prospectus  was timely made  available by the Company  pursuant to Section
3(b) hereof; (II) be available to the extent such Claim is based on a failure of
the Investor to deliver or cause to be delivered the  prospectus  made available
by the  Company;  or (III) 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.  Each Investor shall indemnify
the Company and its officers,  directors and agents  against any claims  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 or on behalf of such
Investor,   expressly  for  use  in  connection  with  the  preparation  of  the
Registration  Statement,  subject  to such  limitations  and  conditions  as are
applicable  to the  Indemnification  provided by the Company to this  Section 6.
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.

         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 be 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,

                                       -7-

<PAGE>



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  reasonable  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. In such event, the Company shall
pay for only one separate  legal counsel for the  Investors;  such legal counsel
shall be  selected  by the  Investors  holding a  majority  in  interest  of the
Registrable Securities included in the Registration Statement to which the Claim
relates.  The failure to deliver written notice to the indemnifying party within
a 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
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 (a) 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; (b) no  seller of  Registrable  Securities  guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities  who was not  guilty of such  fraudulent  misrepresentation;  and (c)
contribution 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  Exchange Act. With a view to making  available to the
Investors the benefits of Rule 144  promulgated  under the Securities 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 Securities Act and the Exchange Act;
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
Securities  Act and the Exchange  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.

         9.  Assignment  of the  Registration  Rights.  The  rights  to have the
Company  register  Registrable  Securities  pursuant to this Agreement  shall be
automatically  assigned by the Investors to any  transferee  of the  Registrable
Securities  (or all or any  portion of any  Debenture  of the  Company  which is
convertible  into such  securities)  only if: (a) the Investor agrees in writing
with the  transferee  or  assignee  to assign  such  rights,  and a copy of such
agreement  is  furnished  to the  Company  within a  reasonable  time after such
assignment,  (b) the Company is, within a reasonable time after such transfer or
assignment,  furnished  with written  notice of (i) the name and address of such
transferee  or  assignee  and (ii) the  securities  with  respect  to which such
registration rights are being transferred or assigned, (c) immediately following
such transfer or assignment the further  disposition  of such  securities by the
transferee or assignee is restricted  under the  Securities  Act and  applicable
state  securities  laws, and (d) at or before the time the Company  received the
written  notice  contemplated  by clause (b) of this sentence the  transferee or
assignee agrees in writing with the Company to be bound by all of the provisions
contained herein;  provided,  however, that in no event shall the rights granted
by this provision be (a) assigned on more than two occasions,  or (b) to greater
than five (5) assignees. In the event of any delay in filing or effectiveness of
the Registration Statement as a result of such assignment, the Company shall not
be liable for any damages  arising from such delay, or the payments set forth in
Section 2(b) hereof.

         10. Amendment of Registration  Rights.  Any provision of this Agreement
may be amended and the observance  thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively),  only with the
written  consent of the Company and  Investors  who hold an eighty (80%) percent
interest of the  Registrable  Securities.  Any  amendment or waiver  effected in
accordance  with this  Section 10 shall be binding  upon each  Investor  and the
Company.

         11.      Miscellaneous.

                 8% CONVERTIBLE DEBENTURE DUE DECEMBER 15, 2000

        THIS DEBENTURE is one of a duly authorized  issue of up to $3,600,000 in
Debentures of GREENMAN TECHNOLOGIES,  INC., a corporation organized and existing
under the laws of the State of Delaware  (the  "Company")  designated  as its 8%
Convertible Debenture Due December 15, 2000.

         FOR VALUE RECEIVED, the Company promises to pay to________________, the
registered    holder   hereof   (the    "Holder"),    the   principal   sum   of
____________________________  and 00/100 (US  $_______)  Dollars on December 15,
2000 (the "Maturity  Date") and to pay interest on the principal sum outstanding
from time to time in arrears upon  conversion as provided herein on December 15,
2000 at the rate of 8% per annum  accruing  from the date of  initial  issuance.
Accrual of interest shall commence on the first such business day to occur after
the date hereof until payment in full of the principal sum has been made or duly
provided for.  Subject to the  provisions  of P. 4 below,  the principal of, and
interest on, this Debenture are payable at the option of the Company,  in shares
of Common Stock of the Company, $.01 par value ("Common Stock"), or in such coin
or currency  of the United  States of America as at the time of payment is legal
tender for payment of public and private debts, at the address last appearing on
the  Debenture  Register of the Company as  designated  in writing by the Holder
from time to time;  provided,  however that this Debenture shall only be payable
in  shares of  Common  Stock on the  Maturity  Date . The  Company  will pay the
principal of and accrued  interest due upon this Debenture on the Maturity Date,
less any amounts  required by law to be deducted,  to the  registered  holder of
this  Debenture as of the tenth day prior to the Maturity  Date and addressed to
such  holder  at the last  address  appearing  on the  Debenture  Register.  The
forwarding  of such  check,  or the  required  number of shares of Common  Stock
determined  pursuant to the provisions of P. 4 below, shall constitute a payment
of  principal  and  interest  hereunder  and shall  satisfy  and  discharge  the
liability for principal and interest on this  Debenture to the extent of the sum
represented by such check plus any amounts so deducted.

         This Debenture is subject to the following additional provisions:

         1. The  Debentures  are  issuable in  denominations  of Fifty  Thousand
Dollars   (US$50,000)  and  integral  multiples  thereof.   The  Debentures  are
exchangeable for an equal aggregate  principal amount of Debentures of different
authorized denominations, as requested by the Holder surrendering the same. No

                                                    

<PAGE>



service charge will be made for such registration or transfer or exchange.

         2. The  Company  shall be entitled  to  withhold  from all  payments of
principal  of, and  interest  on,  this  Debenture  any  amounts  required to be
withheld under the applicable provisions of the United States income tax laws or
other applicable laws at the time of such payments, and Holder shall execute and
deliver all required documentation in connection therewith.

         3. This Debenture has been issued subject to investment representations
of the original  purchaser  hereof and may be  transferred  or exchanged only in
compliance  with the Securities  Act of 1933, as amended (the "Act"),  and other
applicable  state and  foreign  securities  laws.  In the event of any  proposed
transfer of this Debenture,  the Company may require, prior to issuance of a new
Debenture in the name of such other person,  that it receive reasonable transfer
documentation  including  legal  opinions  that the issuance of the Debenture in
such  other  name  does  not and will not  cause a  violation  of the Act or any
applicable  state or  foreign  securities  laws.  Prior to due  presentment  for
transfer of this  Debenture,  the Company and any agent of the Company may treat
the person in whose name this  Debenture  is duly  registered  on the  Company's
Debenture  Register as the owner hereof for the purpose of receiving  payment as
herein  provided and for all other  purposes,  whether or not this  Debenture be
overdue,  and neither the Company nor any such agent shall be affected by notice
to the contrary.

         4. The Holder of this Debenture is entitled,  at its option, to convert
at any time  commencing  sixty (60) days after the date  hereof or such  earlier
date as the Registration  Statement is declared effective (the "Initial Exercise
Date"),  the principal amount of this Debenture together with accrued but unpaid
interest,  provided that the principal  amount is at least US $10,000 (unless if
at the time of such  election to convert the aggregate  principal  amount of all
Debentures  registered  to the  Holder is less  that Ten  Thousand  Dollars  (US
$10,000),  then the whole  amount  thereof)  into shares of Common  Stock of the
Company  ("Debenture  Shares")  at a  conversion  price for each share of Common
Stock ("Conversion Rate") equal to the lessor of subsections (i) or (ii) below:

                  (i)      100% of the  average of the closing bid prices of the
                           Common  Stock on the five  consecutive  trading  days
                           preceding the initial issuance date of this Debenture
                           (the "Issuance Date"); or

                  (ii)     75% of the Market Price;

         Notwithstanding  anything to the contrary  contained herein, the entire
unpaid  balance and accrued  interest  outstanding  on the Maturity  Date hereof
shall  automatically  convert into Common Stock in accordance with the foregoing
Conversion Rate.

         For  purposes of this  Section 4, the Market Price shall be the average
of the  closing  bid prices of the  Common  Stock on the five (5)  trading  days
immediately   preceding  the  Conversion  Date,  as  reported  by  the  National
Association   of   Securities   Dealers,   or  the  closing  bid  price  on  the
over-the-counter market on such date or, in the event the Common Stock is listed
on a stock exchange, the Market Price shall be the closing price on the exchange
on such date,  as  reported  in the Wall  Street  Journal.  Conversion  shall be
effectuated by surrendering the Debentures to be converted to the Company during
usual  business  hours  at the  Company's  principal  offices,  with the form of
conversion  notice  attached  hereto as Exhibit A, executed by the Holder of the
Debenture  evidencing  such  Holder's  intention to convert this  Debenture or a
specified  portion (as above provided) hereof,  and accompanied,  if required by
the Company, by proper assignment hereof in blank.  Interest accrued or accruing
from the date of issuance to the date of conversion shall, at the

                                       -2-

<PAGE>



option of the Company,  be paid in cash or Common Stock upon  conversion  at the
Conversion Rate. No fraction of Shares or scrip representing fractions of shares
will be issued on conversion, but the number of shares issuable shall be rounded
to the nearest whole share. The date on which notice of conversion is given (the
"Conversion  Date") shall be deemed to be the date on which the Holder faxes the
conversion  notice duly  executed,  to the  Company.  Facsimile  delivery of the
conversion  notice  shall be accepted by the Company at  facsimile  number (781)
224-0114;  Att.:  Chuck  Coppa).  Certificates  representing  Common  Stock upon
conversion  will be delivered  within three (3) business  days from the date the
notice of conversion  with the original  Debenture is delivered to the Company's
principal  offices.  In the event that the Holder requests delivery of shares of
Common Stock through the Deposit  Withdrawal Agent Commission system ("DWAC") of
the Depository  Trust Company,  the Company will be deemed to have delivered the
Common Stock upon delivery of instructions and any other necessary  documents to
the Company's transfer agent.

         5. No provision of this Debenture  shall alter or impair the obligation
of the Company,  which is absolute and  unconditional,  to pay the principal of,
and interest on, this Debenture at the time, place, and rate, and in the coin or
currency,  herein  prescribed.  This  Debenture and all other  Debentures now or
hereafter issued of similar terms are direct obligations of the Company.

         6. No recourse shall be had for the payment of the principal of, or the
interest  on, this  Debenture,  or for any claim based  hereon,  or otherwise in
respect hereof, against any incorporator,  shareholder,  officer or director, as
such,  past,  present or future,  of the Company or any  successor  corporation,
whether  by  virtue  of any  constitution,  statute  or rule  of law,  or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance  hereof and as part of the consideration for the issue hereof,
expressly waived and released.

         7. If the Company merges or  consolidates  with another  corporation or
sells or transfers all or substantially  all of its assets to another person and
the holders of the Common Stock are  entitled to receive  stock,  securities  or
property in respect of or in exchange for Common  Stock,  then as a condition of
such  merger,  consolidation,  sale  or  transfer,  the  Company  and  any  such
successor,  purchaser or transferee  agree that the Debenture may  thereafter be
converted  on the terms and subject to the  conditions  set forth above into the
kind and amount of stock,  securities or property  receivable  upon such merger,
consolidation,  sale or  transfer  by a holder of the number of shares of Common
Stock into which this  Debenture  might have been converted  immediately  before
such merger, consolidation, sale or transfer, subject to adjustments which shall
be as nearly  equivalent  as may be  practicable.  In the event of any  proposed
merger,  consolidation  or sale or transfer of all or  substantially  all of the
assets of the  Company (a  "Sale"),  the Holder  hereof  shall have the right to
convert by delivering a Notice of Conversion to the Company  within fifteen (15)
days of receipt of notice of such Sale from the Company. In the event the Holder
hereof  shall  elect not to  convert,  the  Company  may prepay all  outstanding
principal and accrued  interest on this Debenture,  less all amounts required by
law to be deducted,  upon which  tender of payment  following  such notice,  the
right of conversion shall terminate.

         8. The Holder of the Debenture,  by acceptance hereof, agrees that this
Debenture is being  acquired for investment and that such Holder will not offer,
sell or  otherwise  dispose  of this  Debenture  or the  Shares of Common  Stock
issuable  upon  conversion  thereof  except under  circumstances  which will not
result in a  violation  of the Act or any  applicable  state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

         9. This Debenture shall be governed by and construed in accordance with
the  laws  of the  State  of New  York.  Each  of the  parties  consents  to the
jurisdiction  of the federal  courts whose  districts  encompass any part of the
City of New York or the state  courts of the  State of New York  sitting  in the
City of New York

                                       -3-

<PAGE>



in connection  with any dispute  arising under this Agreement and hereby waives,
to the maximum extent  permitted by law, any objection,  including any objection
based on forum non  coveniens,  to the bringing of any such  proceeding  in such
jurisdictions.

                    default hereunder.

Then, or at any time  thereafter,  and in each and every such case,  unless such
Event of Default  shall have been waived in writing by the Holder  (which waiver
shall not be deemed to be a waiver of any  subsequent  default) at the option of
the Holder and in the Holder's  sole  discretion,  the Holder may consider  this
Debenture immediately due and payable,  without presentment,  demand, protest or
notice of any kind, all of which are hereby expressly waived, anything herein or
in any note or other instruments contained to the contrary notwithstanding,  and
the  Holder  may  immediately  enforce  any and all of the  Holder's  rights and

conferring  upon the  Holder  the right to vote or to  receive  dividends  or to
consent  or  receive  notice as a  shareholder  in  respect  of any  meeting  of
shareholders  or any rights  whatsoever as a shareholder of the Company,  unless
and to the extent converted in accordance with the terms hereof.

executed by an officer thereunto duly authorized.

                           GREENMAN TECHNOLOGIES, INC.

                          COMMON STOCK PURCHASE WARRANT


                  1.   Issuance.   In   consideration   of  good  and   valuable
consideration,   the  receipt  of  which  is  hereby  acknowledged  by  GREENMAN

registered assigns (the "Holder") is hereby granted the right to purchase at any
time  commencing two (2) days following the date hereof and until 5:00 P.M., New

Price"), subject to further adjustment as set forth in Section 6 hereof.

                  2. Exercise of Warrants.  This Warrant is exercisable in whole
or in part at the Exercise  Price per share of Common Stock  payable  hereunder,
payable in cash or by certified or official bank check.  Upon  surrender of this
Warrant  Certificate  with the annexed  Notice of Exercise  Form duly  executed,
together  with  payment of the  Exercise  Price for the  shares of Common  Stock
purchased, the Holder shall be entitled to receive a certificate or certificates
for the shares of Common Stock so purchased.

                  3.  Reservation  of Shares.  The Company hereby agrees that at
all times during the term of this  Warrant  there shall be reserved for issuance

number of shares of Common Stock so reserved to cure any  deficiencies,  and, if
necessary,   to  obtain  approval  of  its  stockholders   therefor,   including
authorization  of such  additional  number of  shares of Common  Stock as may be

                  4.  Mutilation  or Loss of Warrant Upon receipt by the Company
of evidence satisfactory to it of the loss, theft,  destruction or mutilation of
this  Warrant,  and (in the  case of  loss,  theft or  destruction)  receipt  of
reasonably  satisfactory  indemnification,  and (in the case of mutilation) upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new  Warrant of like tenor and date and any such lost,  stolen,  destroyed  or
mutilated Warrant shall thereupon become void.

                  5.  Rights of the  Holder.  The Holder  shall  not,  by virtue
hereof, be entitled to any rights of a stockholder in the Company, either at law
or equity,  and the rights of the Holder are limited to those  expressed in this
Warrant and are not  enforceable  against  the Company  except to the extent set
forth herein.

                  6.  Protection Against Dilution.

                      6.1 Adjustment Mechanism. If an adjustment of the Exercise
Price is required  pursuant to this  Section 6, the Holder  shall be entitled to
purchase such number of additional  shares of Common Stock as will cause (i) the
total  number of shares of Common  Stock  the  Holder is  entitled  to  purchase
pursuant to this  Warrant,  multiplied by (ii) the adjusted  purchase  price per
share,  to equal (iii) the dollar amount of the total number of shares of Common
Stock the Holder is entitled to purchase  before  adjustment  multiplied  by the
total purchase price before adjustment.

                      6.2  Capital  Adjustments.  In case of any stock  split or
reverse  stock split,  stock  dividend,  reclassification  of the Common  Stock,
recapitalization,  merger or consolidation, or like capital adjustment affecting
the Common  Stock of the  Company,  the  provisions  of this  Section 6 shall be
applied as if such capital  adjustment event had occurred  immediately  prior to
the date of this  Warrant  and the  original  purchase  price  had  been  fairly
allocated  to the stock  resulting  from such capital  adjustment;  and in other
respects the  provisions of this Section  shall be applied in a fair,  equitable
and reasonable  manner so as to give effect, as nearly as my be, to the purposes
hereof.  A rights offering to  stockholders  shall be deemed a stock dividend to
the extent of the bargain purchase element of the rights.

                      6.3 Merger, Sale of Assets, Etc. If at any time while this
Warrant,  or any portion hereof, is outstanding and unexpired there shall be (i)
a  reorganization  (other  than a  combination,  reclassification,  exchange  or
subdivision  of  shares  otherwise  provided  for  herein),  (ii)  a  merger  or
consolidation  of the Company with or into another  corporation  or other entity
including a merger or consolidation in which the Company is the surviving entity
but the shares of the Company's capital stock  outstanding  immediately prior to
the merger are converted by virtue of the merger into other property, whether in
the form of securities,  cash, or otherwise,  or (iii) a sale or transfer of the
Company's  properties  and assets as, or  substantially  as, an  entirety to any
other person, then as a part of such reorganization, merger, consolidation, sale
or transfer  lawful  provision  shall be made so that the holder of this Warrant
shall thereafter be entitled to receive upon exercise of this

                                       -2-

<PAGE>



Warrant,  during the period  specified  herein and payment of the Exercise Price
then in effect,  the number of shares of stock or other  securities  or property
resulting from such reorganization, merger, consolidation, sale or transfer that
a holder of the shares deliverable upon exercise of this Warrant would have been
entitled  to  receive in such  reorganization,  consolidation,  merger,  sale or
transfer  if  this   Warrant  had  been   exercised   immediately   before  such
reorganization,  merger, consolidation, sale or transfer, all subject to further
adjustment  as  provided in this  Section 6. The  foregoing  provisions  of this
Section 6 shall  similarly apply to successive  reorganization,  consolidations,
mergers,  sales  and  transfers  and to the  stock or  securities  of any  other
corporation or other entity that are at the time receivable upon the exercise of
this Warrant.  If the per-share  consideration  payable to the Holder hereof for
shares in connection with any such  transactions is in a form other than cash or
marketable securities,  then the value of such consideration shall be determined
in good faith by the Company's  Board of Directors.  In all events,  appropriate
adjustment  (as  determined in good faith by the  Company's  Board of Directors)
shall be made in the  application of the provisions of this Warrant with respect
to the rights and interests of the Holder after the transaction, to the end that
the provisions of this Warrant shall be applicable  after that event, as near as
reasonably may be, in relation to any shares or other property deliverable after
that event upon exercise of this Warrant.

                  7. Transfer to Comply with the  Securities  Act;  Registration
Rights.

                  (a) This Warrant has not been registered  under the Securities
Act and has been  issued to the holder for  investment  purposes  and not with a
view to the  distribution of either the Warrant or the Warrant  Shares.  Neither
this  Warrant  nor any of the  Warrant  Shares or any other  security  issued or
issuable  upon  exercise of this  Warrant may be sold,  transferred,  pledged or
hypothecated in the absence of an effective registration statement under the Act
relating to such security or an opinion of counsel  reasonably  satisfactory  to
the Company that  registration  is not required under the  Securities  Act. Each
certificate for the Warrant, the Warrant Shares and any other security issued or
issuable  upon  exercise  of this  Warrant  shall  contain  a legend on the face
thereof, in form and substance satisfactory to counsel for the Company,  setting
forth the restrictions on transfer contained in this Section.

                  (b) The Company agrees to file a registration statement, which
shall include the Warrant  Shares,  on Form S-3 or another  available  form (the
"Registration  Statement"),  pursuant  to the terms of the  Registration  Rights
Agreement between the Company and the Holder dated December _, 1997.

                  8. Notices.  Any notice required or permitted  hereunder shall
be given in writing and shall be deemed  effectively given upon, (a) by personal
delivery  or fax,  or (ii) one  business  day after  deposit  with a  nationally
recognized overnight delivery service such as Federal Express,  with postage and
fees prepaid,  addressed to each of the other parties thereunto  entitled at the
following  addresses,  or at such other  addresses  as a party may  designate by
