assets of the Company or any of its Subsidiaries or the suspension, revocation,
impairment, forfeiture or nonrenewal of any permit, license, authorization or
approval applicable to the Company, its business or operations or any of its

disclosed in any Exchange Act Filings, there is no action, suit, proceeding or
investigation pending or, to the Company's knowledge, currently threatened

Agreements, or from consummating the transactions contemplated hereby or
thereby, or which has had, or could reasonably be expected to have, either
individually or in the aggregate, a Material Adverse Effect or any change in the

<PAGE>

threatened with respect to the Company or any of its Subsidiaries. Except as

nor any of its Subsidiaries is a party to or bound by any currently effective
employment contract, deferred compensation arrangement, bonus plan, incentive
plan, profit sharing plan, retirement agreement or other employee compensation
plan or agreement. To the Company's knowledge, no employee of the Company or any
of its Subsidiaries, nor any consultant with whom the Company or any of its

the right of any such individual to be employed by, or to contract with, the
Company or any of its Subsidiaries because of the nature of the business to be
conducted by the Company or any of its Subsidiaries; and to the Company's
knowledge the continued employment by the Company or any of its Subsidiaries of
its present employees, and the performance of the Company's and its
Subsidiaries' contracts with its independent contractors, will not result in any
such violation. Neither the Company nor any of its Subsidiaries is aware that
any of its employees is obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with their duties to the Company or any of its Subsidiaries. Neither
the Company nor any of its Subsidiaries has received any notice alleging that
any such violation has occurred. Except for employees who have a current
effective employment agreement with the Company or any of its Subsidiaries, no
employee of the Company or any of its Subsidiaries has been granted the right to
continued employment by the Company or any of its Subsidiaries or to any
material compensation following termination of employment with the Company or
any of its Subsidiaries. Except as set forth on Schedule 4.14 or as disclosed in
any Exchange Act Filings, the Company is not aware that any officer, key
employee or group of employees intends to terminate his, her or their employment

Subsidiaries have a present intention to terminate the employment of any
officer, key employee or group of employees.

register any of the Company's or its Subsidiaries' presently outstanding
securities or any of its securities that may hereafter be issued. Except as set
forth on Schedule 4.15 and except as disclosed in Exchange Act Filings, to the
Company's knowledge, no stockholder of the Company or any of its Subsidiaries
has entered into any agreement with respect to the voting of equity securities
of the Company or any of its Subsidiaries.

      4.16 Compliance with Laws; Permits. Neither the Company nor any of its
Subsidiaries is in violation of any applicable statute, rule, regulation, order

Company and its Subsidiaries has all material franchises, permits, licenses and
any similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which could, either individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

connection with the Security Agreement, dated as of the date hereof, by and
between the Company, certain Subsidiaries of the Company and the Purchaser (as
amended, modified or supplemented from time to time, the "Security Agreement"))
under circumstances that would cause the offering of the Securities pursuant to
this Agreement or any of the Related Agreements to be integrated with prior
offerings by the Company for purposes of the Securities Act which would prevent
the Company from selling the Securities pursuant to Rule 506 under the
Securities Act, or any applicable exchange-related stockholder approval
provisions, nor will the Company or any of its affiliates or Subsidiaries take
any action or steps that would cause the offering of the Securities to be

date of this Agreement. Neither the Company nor any of its Subsidiaries will
issue any stop transfer order or other order impeding the sale and delivery of
any of the Securities at such time as the Securities are registered for public
sale or an exemption from registration is available, except as required by state
and federal securities laws.

      4.25 Dilution. The Company specifically acknowledges that its obligation
to issue the shares of Common Stock upon conversion of the Note and exercise of
the Option is binding upon the Company and enforceable regardless of the
dilution such issuance may have on the ownership interests of other shareholders
of the Company.

warrants and agrees that: (i) none of the cash or property that the Company or
any of its Subsidiaries will pay or will contribute to the Purchaser has been or
shall be derived from, or related to, any activity that is deemed criminal under
United States law; and (ii) no contribution or payment by the Company or any of
its Subsidiaries to the Purchaser, to the extent that they are within the
Company's and/or its Subsidiaries' control shall cause the Purchaser to be in
violation of the United States Bank Secrecy Act, the United States International
Money Laundering Control Act of 1986 or the United States International Money
Laundering Abatement and Anti-Terrorist Financing Act of 2001. The Company shall
promptly notify the Purchaser if any of these representations ceases to be true
and accurate regarding the Company or any of its Subsidiaries. The Company
agrees to provide the Purchaser any additional information regarding the Company
or any of its Subsidiaries that the Purchaser deems necessary or convenient to
ensure compliance with all applicable laws concerning money laundering and
similar activities. The Company understands and agrees that if at any time it is
discovered that any of the foregoing representations are incorrect, or if
otherwise required by applicable law or regulation related to money laundering
similar activities, the Purchaser may undertake appropriate actions to ensure
compliance with applicable law or regulation, including but not limited to
segregation and/or redemption of the Purchaser's investment in the Company. The
Company further understands that the Purchaser may release confidential
information about the Company and its Subsidiaries and, if applicable, any

light of relevant rules and regulations under the laws set forth in subsection
(ii) above.

      6.1 Stop-Orders. The Company will advise the Purchaser, promptly after it
receives notice of issuance by the Securities and Exchange Commission (the
"SEC"), any state securities commission or any other regulatory authority of any
stop order or of any order preventing or suspending any offering of any


                                       15

securities of the Company, or of the suspension of the qualification of the
Common Stock of the Company for offering or sale in any jurisdiction, or the
initiation of any proceeding for any such purpose.

      6.2 Listing. The Company shall promptly secure the listing of the shares
of Common Stock issuable upon conversion of the Note and upon the exercise of
the Option on the AMEX (the "Principal Market") upon which shares of Common
Stock are listed (subject to official notice of issuance) and shall maintain
such listing so long as any other shares of Common Stock shall be so listed. The
Company will maintain the listing of its Common Stock on the Principal Market,
and will comply in all material respects with the Company's reporting, filing
and other obligations under the bylaws or rules of the AMEX and such other
exchanges, as applicable.

      6.3 Market Regulations. The Company shall notify the SEC, the National
Association of Securities Dealers ("NASD") and applicable state authorities, in
accordance with their requirements, of the transactions contemplated by this
Agreement, and shall take all other necessary action and proceedings as may be
required and permitted by applicable law, rule and regulation, for the legal and
valid issuance of the Securities to the Purchaser and promptly provide copies
thereof to the Purchaser.

      6.4 Reporting Requirements. The Company will timely file with the SEC all
reports required to be filed pursuant to the Exchange Act and refrain from
terminating its status as an issuer required by the Exchange Act to file reports
thereunder even if the Exchange Act or the rules or regulations thereunder would
permit such termination.

      6.5 Use of Funds. The Company agrees that it will use the proceeds of the
Note and the Option for immaterial equipment purchases and general working
capital purposes only.

      6.6 Access to Facilities. Each of the Company and each of its Subsidiaries
will permit any representatives designated by the Purchaser (or any successor of
the Purchaser), upon reasonable notice and during normal business hours, at such
person's expense and accompanied by a representative of the Company, to:

            (a) visit and inspect any of the properties of the Company or any of
      its Subsidiaries;

            (b) examine the corporate and financial records of the Company or
      any of its Subsidiaries (unless such examination is not permitted by
      federal, state or local law or by contract) and make copies thereof or
      extracts therefrom; and

            (c) discuss the affairs, finances and accounts of the Company or any
      of its Subsidiaries with the directors, officers and independent
      accountants of the Company or any of its Subsidiaries.

Notwithstanding the foregoing, neither the Company nor any of its Subsidiaries

Regulation FD, under the federal securities laws.


                                       16
<PAGE>

      6.7 Taxes. Each of the Company and each of its Subsidiaries will promptly
pay and discharge, or cause to be paid and discharged, when due and payable, all
lawful taxes, assessments and governmental charges or levies imposed upon the
income, profits, property or business of the Company and its Subsidiaries;
provided, however, that any such tax, assessment, charge or levy need not be
paid if the validity thereof shall currently be contested in good faith by
appropriate proceedings and if the Company and/or such Subsidiary shall have set
aside on its books adequate reserves with respect thereto, and provided,
further, that the Company and its Subsidiaries will pay all such taxes,
assessments, charges or levies forthwith upon the commencement of proceedings to
foreclose any lien which may have attached as security therefor.

      6.8 Insurance. Each of the Company and its Subsidiaries will keep its
assets which are of an insurable character insured by financially sound and
reputable insurers against loss or damage by fire, explosion and other risks
customarily insured against by companies in similar business similarly situated
as the Company and its Subsidiaries; and the Company and its Subsidiaries will
maintain, with financially sound and reputable insurers, insurance against other
hazards and risks and liability to persons and property to the extent and in the
manner which the Company reasonably believes is customary for companies in
similar business similarly situated as the Company and its Subsidiaries and to
the extent available on commercially reasonable terms. The Company, and each of
its Subsidiaries will jointly and severally bear the full risk of loss from any
loss of any nature whatsoever with respect to the assets pledged to the
Purchaser as security for its obligations hereunder and under the Related
Agreements. At the Company's and each of its Subsidiaries' joint and several
cost and expense in amounts and with carriers reasonably acceptable to
Purchaser, the Company and each of its Subsidiaries shall (i) keep all its
insurable properties and properties in which it has an interest insured against
the hazards of fire, flood, sprinkler leakage, those hazards covered by extended
coverage insurance and such other hazards, and for such amounts, as is customary
in the case of companies engaged in businesses similar to the Company's or the
respective Subsidiary's including business interruption insurance; (ii) maintain
a bond in such amounts as is customary in the case of companies engaged in
businesses similar to the Company's or the respective Subsidiary's insuring
against larceny, embezzlement or other criminal misappropriation of insured's
officers and employees who may either singly or jointly with others at any time
have access to the assets or funds of the Company or any of its Subsidiaries
either directly or through governmental authority to draw upon such funds or to
direct generally the disposition of such assets; (iii) maintain public and
product liability insurance against claims for personal injury, death or
property damage suffered by others; (iv) maintain all such worker's compensation
or similar insurance as may be required under the laws of any state or
jurisdiction in which the Company or the respective Subsidiary is engaged in
business; and (v) furnish Purchaser with (x) copies of all policies and evidence
of the maintenance of such policies at least thirty (30) days before any
expiration date, (y) excepting the Company's workers' compensation policy,
endorsements to such policies naming Purchaser as "co-insured" or "additional
insured" and appropriate loss payable endorsements in form and substance
satisfactory to Purchaser, naming Purchaser as loss payee, and (z) evidence that
as to Purchaser the insurance coverage shall not be impaired or invalidated by
any act or neglect of the Company or any Subsidiary and the insurer will provide
Purchaser with at least thirty (30) days notice prior to cancellation. The
Company and each Subsidiary shall instruct the insurance carriers that in the
event of any loss thereunder, the carriers shall make payment for such loss to
the Company and/or the Subsidiary and Purchaser jointly. In the event that as of


                                       17
<PAGE>

the date of receipt of each loss recovery upon any such insurance, the Purchaser
has not declared an event of default with respect to this Agreement or any of
the Related Agreements, then the Company and/or such Subsidiary shall be
permitted to direct the application of such loss recovery proceeds toward
investment in property, plant and equipment that would comprise "Collateral"
secured by Purchaser's security interest pursuant to its security agreement,
with any surplus funds to be applied toward payment of the obligations of the
Company to Purchaser. In the event that Purchaser has properly declared an event
of default with respect to this Agreement or any of the Related Agreements, then
all loss recoveries received by Purchaser upon any such insurance thereafter may
be applied to the obligations of the Company hereunder and under the Related
Agreements, in such order as the Purchaser may determine. Any surplus (following
satisfaction of all Company obligations to Purchaser) shall be paid by Purchaser
to the Company or applied as may be otherwise required by law. Any deficiency
thereon shall be paid by the Company or the Subsidiary, as applicable, to
Purchaser, on demand.

      6.9 Intellectual Property. Each of the Company and each of its
Subsidiaries shall maintain in full force and effect its existence, rights and
franchises and all licenses and other rights to use Intellectual Property owned
or possessed by it and reasonably deemed to be necessary to the conduct of its
business.

      6.10 Properties. Each of the Company and each of its Subsidiaries will
keep its properties in good repair, working order and condition, reasonable wear
and tear excepted, and from time to time make all needful and proper repairs,
renewals, replacements, additions and improvements thereto; and each of the
Company and each of its Subsidiaries will at all times comply with each
provision of all leases to which it is a party or under which it occupies
property if the breach of such provision could, either individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

      6.11 Confidentiality. The Company agrees that it will not disclose, and
will not include in any public announcement, the name of the Purchaser, unless
expressly agreed to by the Purchaser or unless and until such disclosure is
required by law or applicable regulation, and then only to the extent of such
requirement. Notwithstanding the foregoing, the Company may disclose Purchaser's
identity and the terms of this Agreement to its current and prospective debt and
equity financing sources.

      6.12 Required Approvals. (I) For so long as twenty-five percent (25%) of
the principal amount of the Note is outstanding, the Company, without the prior
written consent of the Purchaser, shall not, and shall not permit any of its
Subsidiaries to:

            (a) (i) directly or indirectly declare or pay any dividends, other
      than dividends paid to the Company or any of its wholly-owned
      Subsidiaries, (ii) issue any preferred stock that is manditorily
      redeemable by the holder thereof prior to the one year anniversary of the
      Maturity Date or (iii) redeem any of its preferred stock or other equity
      interests;

            (b) liquidate, dissolve or effect a material reorganization (it
      being understood that in no event shall the Company dissolve, liquidate or
      merge with any other person or entity (unless the Company is the surviving
      entity);

<PAGE>

            (c) become subject to (including, without limitation, by way of
      amendment to or modification of) any agreement or instrument which by its
      terms would (under any circumstances) restrict the Company's or any of its
      Subsidiaries right to perform the provisions of this Agreement, any
      Related Agreement or any of the agreements contemplated hereby or thereby;

            (d) materially alter or change the scope of the business of the
      Company and its Subsidiaries taken as a whole;

            (e) (i) create, incur, assume or suffer to exist any indebtedness
      (exclusive of trade debt and debt incurred to finance the purchase of
      equipment (not in excess of five percent (5%) per annum of the fair market
      value of the Company's assets) whether secured or unsecured other than (x)
      the Company's indebtedness to Laurus, (y) indebtedness set forth on
      Schedule 6.12(e) attached hereto and made a part hereof and any
      refinancings or replacements thereof on terms no less favorable to the
      Purchaser than the indebtedness being refinanced or replaced, and (z) any
      debt incurred in connection with the purchase of assets in the ordinary
      course of business, or any refinancings or replacements thereof on terms
      no less favorable to the Purchaser than the indebtedness being refinanced
      or replaced; (ii) cancel any debt owing to it in excess of $50,000 in the
      aggregate during any 12 month period; (iii) assume, guarantee, endorse or
      otherwise become directly or contingently liable in connection with any
      obligations of any other Person, and except the endorsement of negotiable
      instruments by the Company for deposit or collection or similar
      transactions in the ordinary course of business or guarantees of
      indebtedness otherwise permitted to be outstanding pursuant to this clause
      (e); and

            (f) with respect to the Company and each of its Subsidiaries (other
      than GreenMan Technologies of Iowa, Inc. ("GreenMan Iowa"), GreenMan
      Technologies of California, Inc. ("GreenMan California") and the
      Immaterial Subsidiaries) transfer any of their respective assets, or merge
      with or consolidate into, or maintain any assets in, make any investments
      in or make any loans or advances to, GreenMan Iowa, GreenMan California or
      any Immaterial Subsidiary, other than immaterial asset transfers, assets
      maintained, investments, loans or advances, in each case, made in the
      ordinary course of business.

(II) The Company, without the prior written consent of the Purchaser, shall not,
and shall not permit any of its Subsidiaries to, create or acquire any
Subsidiary after the date hereof unless (i) such Subsidiary is a wholly-owned
Subsidiary of the Company and (ii) such Subsidiary becomes a party to the Master
Security Agreement, the Stock Pledge Agreement and the Subsidiary Guaranty
(either by executing a counterpart thereof or an assumption or joinder agreement
in respect thereof) and, to the extent required by the Purchaser, satisfies each
condition of this Agreement and the Related Agreements as if such Subsidiary
were a Subsidiary on the Closing Date.

      6.13 Reissuance of Securities. The Company agrees to reissue certificates
representing the Securities without the legends set forth in Section 5.8 above
at such time as:


                                       19
<PAGE>

            (a) the holder thereof is permitted to dispose of such Securities
      pursuant to Rule 144(k) under the Securities Act; or

            (b) upon resale subject to an effective registration statement after
      such Securities are registered under the Securities Act.

The Company agrees to cooperate with the Purchaser in connection with all
resales pursuant to Rule 144(d) and Rule 144(k) and provide legal opinions
necessary to allow such resales provided the Company and its counsel receive
reasonably requested representations from the selling Purchaser and broker, if
any.

      6.14 Opinion. On the Closing Date, the Company will deliver to the
Purchaser an opinion acceptable to the Purchaser from the Company's external
legal counsel. The Company will provide, at the Company's expense, such other
legal opinions in the future as are deemed reasonably necessary by the Purchaser
(and acceptable to the Purchaser) in connection with the conversion of the Note
and exercise of the Option.

      6.15 Margin Stock. The Company will not permit any of the proceeds of the
Note or the Option to be used directly or indirectly to "purchase" or "carry"
"margin stock" or to repay indebtedness incurred to "purchase" or "carry"
"margin stock" within the respective meanings of each of the quoted terms under
Regulation U of the Board of Governors of the Federal Reserve System as now and
from time to time hereafter in effect.

      6.16 Financing Right of First Refusal. (a) The Company hereby grants to
the Purchaser a right of first refusal to provide any Additional Financing (as
defined below) to be issued by the Company and/or any of its Subsidiaries,
subject to the following terms and conditions. Prior to the incurrence of
additional indebtedness or the issuance of any additional equity interests (an
"Additional Financing"), in each case, after the date hereof, the Company and/or
any Subsidiary of the Company, as the case may be, shall notify the Purchaser of
its intention to enter into such Additional Financing, together with the terms
that such proposed Additional Financing will be subject to. In connection
therewith, the Company and/or the applicable Subsidiary thereof shall submit a
fully executed term sheet (a "Proposed Term Sheet") to the Purchaser setting
forth the terms, conditions and pricing of any such Additional Financing (such
financing to be negotiated on "arm's length" terms and the terms thereof to be
negotiated in good faith) proposed to be entered into by the Company and/or such
Subsidiary. The Purchaser shall have the right, but not the obligation, to agree
to provide such Additional Financing to the Company and/or such Subsidiary on
terms no less favorable than those outlined in Proposed Term Sheet within ten
business days of receipt of any such Proposed Term Sheet. If the provisions of
the Purchaser's term sheet are at least as favorable to the Company or such
Subsidiary, as the case may be, as the provisions of the Proposed Term Sheet,
the Company and/or such Subsidiary shall enter into the Additional Financing
outlined in the Purchaser's term sheet. Notwithstanding anything in the
foregoing to the contrary, the term "Additional Financing" shall not include (x)
trade accounts payable or (y) indebtedness incurred at the time of acquisition
of equipment so long as the proceeds of such indebtedness are used to pay all or
a portion of the purchase price of such equipment.


                                       20
<PAGE>

            (b) The Company will not, and will not permit its Subsidiaries to,
agree, directly or indirectly, to any restriction with any person or entity
which limits the ability of the Purchaser to consummate an Additional Financing
with the Company or any of its Subsidiaries.

      6.17 Dissolution of Subsidiaries. On or prior to thirty 30 days following
the Closing Date (or such longer period as the Purchaser may agree to in its
sole discretion), the Company shall, or shall cause, the dissolution of each
Immaterial Subsidiary or cause each such Immaterial Subsidiary to become party
to each of the Subsidiary Guaranty, Master Security Agreement and Stock Pledge
Agreement through execution of a joinder agreement in form and substance
satisfactory to the Purchaser.

      6.18 Authorization and Reservation of Shares. The Company shall at all
times have authorized and reserved a sufficient number of shares of Common Stock
to provide for the conversion of the Note and exercise of the Options.

      7. Covenants of the Purchaser. The Purchaser covenants and agrees with the
Company as follows:

      7.1 Confidentiality. The Purchaser agrees that it will not disclose, and
will not include in any public announcement, the name of the Company, unless
expressly agreed to by the Company or unless and until such disclosure is
required by law or applicable regulation, and then only to the extent of such
requirement.

      7.2 Non-Public Information. The Purchaser agrees not to effect any sales
in the shares of the Company's Common Stock while in possession of material,
non-public information regarding the Company if such sales would violate
applicable securities law.

      7.3 Limitation on Acquisition of Common Stock of the Company.
Notwithstanding anything to the contrary contained in this Agreement, any
Related Agreement or any document, instrument or agreement entered into in
connection with any other transactions between the Purchaser and the Company,
the Purchaser may not acquire stock in the Company (including, without
limitation, pursuant to a contract to purchase, by exercising an option or
warrant, by converting any other security or instrument, by acquiring or
exercising any other right to acquire, shares of stock or other security
convertible into shares of stock in the Company, or otherwise, and such
contracts, options, warrants, conversion or other rights shall not be
enforceable or exercisable) to the extent such stock acquisition would cause any
interest (including any original issue discount) payable by the Company to the
Purchaser not to qualify as "portfolio interest" within the meaning of Section
881(c)(2) of the Code, by reason of Section 881(c)(3) of the Code, taking into
account the constructive ownership rules under Section 871(h)(3)(C) of the Code
(the "Stock Acquisition Limitation"). The Stock Acquisition Limitation shall
automatically become null and void without any notice to the Company upon the
earlier to occur of either (a) the Company's delivery to the Purchaser of a
Notice of Redemption (as defined in the Note) or (b) the existence of an Event
of Default (as defined in the Note) at a time when the average closing price of
the Company's common stock as reported by Bloomberg, L.P. on the Principal
Market for the immediately preceding five trading days is greater than or equal
to 150% of the Fixed Conversion Price (as defined in the Note).


                                       21
<PAGE>

      8. Covenants of the Company and Purchaser Regarding Indemnification.

      8.1 Company Indemnification. The Company agrees to indemnify, hold
harmless, reimburse and defend the Purchaser, each of the Purchaser's officers,
directors, agents, affiliates, control persons, and principal shareholders,
against any claim, cost, expense, liability, obligation, loss or damage
(including reasonable legal fees) of any nature, incurred by or imposed upon the
Purchaser which results, arises out of or is based upon: (i) any
misrepresentation by the Company or any of its Subsidiaries or breach of any
warranty by the Company or any of its Subsidiaries in this Agreement, any other
Related Agreement or in any exhibits or schedules attached hereto or thereto; or
(ii) any breach or default in performance by Company or any of its Subsidiaries
of any covenant or undertaking to be performed by Company or any of its
Subsidiaries hereunder, under any other Related Agreement or any other agreement
entered into by the Company and/or any of its Subsidiaries and Purchaser
relating hereto or thereto.

      8.2 Purchaser's Indemnification. Purchaser agrees to indemnify, hold
harmless, reimburse and defend the Company and each of the Company's officers,
directors, agents, affiliates, control persons and principal shareholders, at
all times against any claim, cost, expense, liability, obligation, loss or
damage (including reasonable legal fees) of any nature, incurred by or imposed
upon the Company which results, arises out of or is based upon: (i) any
misrepresentation by Purchaser or breach of any warranty by Purchaser in this
Agreement or in any exhibits or schedules attached hereto or any Related
Agreement; or (ii) any breach or default in performance by Purchaser of any
covenant or undertaking to be performed by Purchaser hereunder, or any other
agreement entered into by the Company and Purchaser relating hereto.

      9. Conversion of Convertible Note.

      9.1 Mechanics of Conversion.

            (a) Provided the Purchaser has notified the Company of the
      Purchaser's intention to sell the Note Shares and the Note Shares are
      included in an effective registration statement or are otherwise exempt
      from registration when sold: (i) upon the conversion of the Note or part
      thereof, the Company shall, at its own cost and expense, take all
      necessary action (including the issuance of an opinion of counsel
      reasonably acceptable to the Purchaser following a request by the
      Purchaser) to assure that the Company's transfer agent shall issue shares
      of the Company's Common Stock in the name of the Purchaser (or its
      nominee) or such other persons as designated by the Purchaser in
      accordance with Section 9.1(b) hereof and in such denominations to be
      specified representing the number of Note Shares issuable upon such
      conversion; and (ii) the Company warrants that no instructions other than
      these instructions have been or will be given to the transfer agent of the
      Company's Common Stock and that after the Effectiveness Date (as defined
      in the Registration Rights Agreement) the Note Shares issued will be
      freely transferable subject to the prospectus delivery requirements of the
      Securities Act and the provisions of this Agreement, and will not contain
      a legend restricting the resale or transferability of the Note Shares.


                                       22
<PAGE>

            (b) Purchaser will give notice of its decision to exercise its right
      to convert the Note or part thereof by telecopying or otherwise delivering
      an executed and completed notice of the number of shares to be converted
      to the Company (the "Notice of Conversion"). The Purchaser will not be
      required to surrender the Note until the Purchaser receives a credit to
      the account of the Purchaser's prime broker through the DWAC system (as
      defined below), representing the Note Shares or until the Note has been
      fully satisfied. Each date on which a Notice of Conversion is telecopied
      or delivered to the Company in accordance with the provisions hereof shall
      be deemed a "Conversion Date." Pursuant to the terms of the Notice of
      Conversion, the Company will issue instructions to the transfer agent
      accompanied by an opinion of counsel within one (1) business day of the
      date of the delivery to the Company of the Notice of Conversion and shall
      cause the transfer agent to transmit the certificates representing the
      Conversion Shares to the Holder by crediting the account of the
      Purchaser's prime broker with the Depository Trust Company ("DTC") through
      its Deposit Withdrawal Agent Commission ("DWAC") system within three (3)
      business days after receipt by the Company of the Notice of Conversion
      (the "Delivery Date").

            (c) The Company understands that a delay in the delivery of the Note
      Shares in the form required pursuant to Section 9 hereof beyond the
      Delivery Date could result in economic loss to the Purchaser. In the event
      that the Company fails to direct its transfer agent to deliver the Note
      Shares to the Purchaser via the DWAC system within the time frame set
      forth in Section 9.1(b) above and the Note Shares are not delivered to the
      Purchaser by the Delivery Date, as compensation to the Purchaser for such
      loss, the Company agrees to pay late payments to the Purchaser for late
      issuance of the Note Shares in the form required pursuant to Section 9
      hereof upon conversion of the Note in the amount equal to the greater of:
      (i) $500 per business day after the Delivery Date; and (ii) the
      Purchaser's actual damages from such delayed delivery. Notwithstanding the
      foregoing, the Company will not owe the Purchaser any late payments if the
      delay in the delivery of the Note Shares beyond the Delivery Date is
      solely out of the control of the Company and the Company is actively
      trying to cure the cause of the delay. The Company shall pay any payments
      incurred under this Section in immediately available funds upon demand
      and, in the case of actual damages, accompanied by reasonable
      documentation of the amount of such damages. Such documentation shall show
      the number of shares of Common Stock the Purchaser is forced to purchase
      (in an open market transaction) which the Purchaser anticipated receiving
      upon such conversion, and shall be calculated as the amount by which (A)
      the Purchaser's total purchase price (including customary brokerage
      commissions, if any) for the shares of Common Stock so purchased exceeds
      (B) the aggregate principal and/or interest amount of the Note, for which
      such Conversion Notice was not timely honored.

Nothing contained herein or in any document referred to herein or delivered in
connection herewith shall be deemed to establish or require the payment of a
rate of interest or other charges in excess of the maximum permitted by
applicable law. In the event that the rate of interest or dividends required to
be paid or other charges hereunder exceed the maximum amount permitted by such
law, any payments in excess of such maximum shall be credited against amounts
owed by the Company to a Purchaser and thus refunded to the Company.

      10. Registration Rights.

      10.1 Registration Rights Granted. The Company hereby grants registration
rights to the Purchaser pursuant to a Registration Rights Agreement dated as of

will issue any securities with a continuously variable/floating conversion
feature which are or could be (by conversion or registration) free-trading

full repayment or conversion of the Note (together with all accrued and unpaid
interest and fees related thereto) (the "Exclusion Period").

      11. Miscellaneous.

      11.1 Governing Law. THIS AGREEMENT AND EACH RELATED AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK,

exercise any right, power or remedy accruing to any party, upon any breach,
default or noncompliance by another party under this Agreement or the Related
Agreements, shall impair any such right, power or remedy, nor shall it be
construed to be a waiver of any such breach, default or noncompliance, or any
acquiescence therein, or of or in any similar breach, default or noncompliance
thereafter occurring. All remedies, either under this Agreement or the Related
Agreements, by law or otherwise afforded to any party, shall be cumulative and
