Shares, in whatever form , including but not limited to, cash or stock

5. Obligor's Representations and Warranties. Subject to all disclosures made by
Obligor (i) in all of Obligor's filings prior to the date hereof with the
Securities and Exchange Commission, including Obligor's Quarterly Report on Form
10-Q for the period ending September 30, 2002 and its various Current Reports on
Form 8-K and (ii) Obligor's disclosure schedules to the Exchange Agreement,
Obligor hereby represents and warrants the following to the Secured Party:

         5.1 Organization and Existence. Obligor is duly incorporated, validly
existing and in good standing under the laws of the District of Columbia.
Obligor has full corporate power and authority to own and hold the properties
and assets it now owns and holds and to carry on its business as and where such
properties are now owned or held and such business is now conducted. Obligor is
duly licensed or qualified to do business as a foreign corporation and is in
good standing in the states in which the character of the properties and assets
now owned or held by it or the nature of the business now conducted by it
requires it to be so licensed or qualified, except where the failure to be so
qualified or in good standing would not reasonably be expected to have a
material adverse effect on the business, financial condition or results of
operations of Obligor.

         5.2 Authority and Approval. Obligor has the corporate power and
authority to execute and deliver this Agreement, to consummate the transactions
contemplated hereby and to perform all the terms and conditions hereof to be
performed by it. The execution and delivery by Obligor of this Agreement, the
performance by Obligor of all the terms and conditions hereof to be performed by
it and the consummation of the transactions contemplated hereby have been duly
authorized and approved by all requisite corporate action of Obligor. This
Agreement constitutes the valid and binding obligation of Obligor enforceable in
accordance with its terms, except as such enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting enforcement of creditors' rights generally and by general principles
of equity (whether applied in a proceeding at law or in equity).

         5.3 No Conflict. This Agreement, and the execution and delivery by
Obligor of this Agreement does not, and the fulfillment and compliance with the
terms and conditions hereof, and the consummation of the transactions
contemplated hereby will not:

              (a) conflict with any of, or require the consent of any person or
entity under, the terms, conditions or provisions of the charter documents or
bylaws or equivalent governing instruments of Obligor;

                                       4
<PAGE>

              (b) violate any provision of, or require any consent,
authorization or approval under, any law, statute, ordinance, rule or regulation
or any judicial, administrative or arbitration order, award, judgment, writ,
injunction or decree applicable to Obligor; or

              (c) result in the creation of any material lien, charge or
encumbrance on the assets of Obligor under any indenture, mortgage, lien, lease
or contract.

         5.4 Pledged Shares. The taking of possession by the Secured Party or by
its agent, or by the Broker pursuant to the Pledged Collateral Account
Agreement, for the purpose of accepting delivery of the Pledged Shares, shall
perfect and establish the first priority of the Secured Party's security
interest in such Pledged Shares. Except as set forth in this Section 5.4 or as
may be required under the UCC, no action is necessary to perfect or otherwise
protect such security interest in such Pledged Shares and the Obligor has not
granted a security interest in the Pledged Shares to any other person.

         5.5 Other Liens. Obligor owns the Collateral free and clear of any
Lien, except for the security interests created by this Agreement and by the
Pledged Collateral Account Agreement. No effective financing statement or other
instrument similar in effect covering all or any part of the Collateral is on
file in any recording office, except such as may have been filed in connection
with this Agreement.

         5.6 Lien Priority and Perfection of Security Interest in the
Collateral. This Agreement creates a valid first priority security interest in
the Collateral. No other authorization, approval or other action by any
governmental authority or any other person or entity is necessary to grant the
security interest in the Collateral contemplated hereby, allow Obligor to
perform its obligations hereunder or permit the Secured Party to exercise its
rights and remedies hereunder.

6. Obligor's Covenants.

         6.1 Delivery of the Pledged Shares. Obligor shall deliver to Agent,
which the Secured Party hereby appoints as its agent for the purpose of
accepting delivery of and holding the Pledged Shares, simultaneously with or
promptly following the execution and delivery of this Agreement, all
certificates representing the Pledged Shares endorsed in blank for transfer or
accompanied by stock powers executed in blank for transfer of the Pledged
Shares, with medallion guarantees. Prior to delivery to the Agent, all such
certificates representing Pledged Shares shall be held in trust by Obligor for
the benefit of the Secured Party pursuant hereto. All such certificates shall be
delivered in suitable form for transfer by delivery or shall be accompanied by
duly executed instruments of transfer or assignment in blank, substantially in
the form provided in Exhibit B attached hereto. Obligor further agrees to
execute and deliver to the Secured Party such UCC or other applicable financing
statements or other filing or registration as may be reasonably requested by the
Secured Party in order to perfect and protect the security interest created
hereby in the Pledged Shares or to deliver to the Secured Party such instruments
and similar documents with respect to the Pledged Shares as the Secured Party
may reasonably request.

         6.2 Pledged Collateral Account. Prior to any open market sale or
transfer of the Pledge Shares on any stock exchange or trading market

                                       5
<PAGE>

(including, if applicable, the OTC Bulletin Board) where the Pledge Shares are
then traded (the "Stock Exchange"), Obligor shall execute and deliver a Pledged
Collateral Account Agreement substantially in the form of that attached hereto
as Exhibit A, to a broker or brokers to be identified by Obligor and Secured
Party by mutual consent (the "Broker"), for purposes of establishing an Account
or Accounts among Obligor, Secured Party and Broker to remain effective until
the earlier of (i) the date on which the Secured Obligations shall have been
paid in full and the security interest is thereby released; or (ii) the
completion of any foreclosure of Secured Party's security interests as provided
herein (the "Termination Date"). If prior to the Termination Date, the parties
determine to close such Account or Accounts, the Obligor shall cause any
applicable Collateral to be redelivered to the Agent.

         6.3 Distributions. In the event that any Distributions are to be
delivered to Obligor with respect to any Pledged Shares, and no Event of Default
has occurred or is continuing, then fifty percent (50%) of such Distributions
shall be delivered directly to Obligor and the other fifty percent (50%) shall
be delivered directly to Agent for the benefit of Secured Party. If an Event of
Default in the performance of the Secured Obligations has occurred and is
continuing through no fault of the Agent and/or the Broker, then any and all
such Distributions are to be delivered directly to the Agent (accompanied, if
appropriate, by stock powers executed in blank for transfer or another
instrument of transfer) for the benefit of Secured Party, up to any deficiency
amount owed to the Secured Party pursuant to the redemption schedule contained
in the COD.

         6.4 Further Assurances With Respect to the Collateral.

         (a) Obligor agrees that at any time, at Obligor's expense, Obligor will
promptly execute and deliver all such further instruments and documents, and
take all such further action, that may be necessary or that the Secured Party
may reasonably request, in order to perfect and protect any security interest in
the Collateral granted or purported to be granted hereby or to enable Secured
Party to exercise and enforce their rights and remedies hereunder with respect
to any Collateral. Without limiting the generality of the foregoing, Obligor
will, at the Secured Party's request: (i) execute and file such financing or
continuation statements, or amendments thereto, and such other instruments or
notices as may be necessary, or as the Secured Party may reasonably request, in
order to perfect and preserve the security interests granted or purported to be
granted hereby in the Collateral.

         (b) Obligor will furnish to the Secured Party, from time-to-time,
statements and schedules further identifying and describing the Collateral and
such other reports in connection with the Collateral as the Secured Party may
reasonably request, all in reasonable detail, including but not limited to
monthly reports or statements in connection with sales pursuant to the Pledged
Collateral Account Agreement.

         6.5 Transfer of Collateral. Except in the case of an open market sale
(not pre-arranged) by Obligor of the Pledged Shares on a Stock Exchange, whether
by means of an effective registration statement or by means of Rule 144 pursuant
to the Pledged Collateral Account Agreement, Obligor shall not sell, assign,
transfer (by operation or law or otherwise), pledge as collateral, or grant or

                                       6
<PAGE>

create any security interest, lien or other encumbrance with respect to any of
the Collateral without the prior written consent of the Secured Party. Obligor
agrees to promptly upon settlement of such sales, to transfer to Secured Party
fifty percent (50%) of the proceeds of such sales, net of all reasonable and
customary broker's commissions.


7. Remedies. If an Event of Default shall have occurred and remain uncured:

         7.1 UCC Remedies With Respect to the Collateral. To the extent
permitted by law, the Secured Party may exercise in respect of the Collateral,
in addition to other rights and remedies provided for in this Agreement or
otherwise available to it, all the rights and remedies of a secured party under
the UCC (whether or not the UCC applies to the affected Collateral).

         7.2 Application of Collateral. All cash proceeds received by the
Secured Party from the collection of or other realization of any part of the
Collateral shall be applied by the Secured Party against the performance of the
Secured Obligations pursuant to the redemption schedule for the Series B
Preferred Stock contained in the COD and in the Certificate of Designation for
the Series A Preferred Stock.. Any surplus of such cash or cash proceeds held by
the Secured Party and remaining after performance in full of all the Secured
Obligations shall be paid over to Obligor or to whomever may be lawfully
entitled to receive such surplus.

         7.3 Pledged Shares.

         (a) Certain Remedies. Upon the occurrence of and during the continuance
of an Event of Default, Secured Party may exercise in respect of the Collateral,
in addition to other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party under the UCC
and may also require the Obligor to, and the Obligor hereby agrees that it will
at its expense, require the Agent to deliver the Collateral to the Secured
Party. Secured Party may sell all or any part of the Collateral as a whole or in
parcels either by public auction or private sale or other method of disposition.
The Secured Party may bid at any public sale on all or any portion of the
Collateral. Secured Party shall give Obligor reasonable notice of the time and
place of any public sale or of the time after which any private sale or other
disposition of the Collateral is to be made, and notice given at least ten (10)
business days before the time of the sale or other disposition shall be
conclusively presumed to be reasonable.

         (b) No Obligation to Sell. Notwithstanding Section 7.3(a), Secured
Party shall be under no obligation to offer to sell the Pledged Shares. In the
event the Secured Party offers to sell the Pledged Shares, the Secured Party
shall be under no obligation to consummate a sale of the Pledged Shares if, in
their reasonable business judgment, none of the offers received by them
reasonably approximate the fair value of the Pledged Shares.

         (c) Strict Foreclosure. In the event the Secured Party elects not to
sell the Pledged Shares, the Secured Party may elect to follow the procedures
set forth in the UCC for retaining the Pledged Shares in satisfaction of the
Secured Obligations, subject to the Obligor's rights under such procedures.

                                       7
<PAGE>

         (d) Rights. Until the occurrence of an Event of Default, all legal and
beneficial ownership rights to the Pledged Shares shall remain with the Obligor
during such time as the Pledged Shares are held by the Agent, including, but not
limited to, any right to vote thereon.

8. Appointment of Agent.

         8.1 Attorneys-In-Fact. Upon the occurrence and continuance of an Event
of Default, Obligor hereby irrevocably appoints the Secured Party as Obligor's
attorney-in-fact with respect to the Collateral and the Agent as Obligor's
attorney-in-fact with respect to the Pledged Shares, with full authority to act
for Obligor and in the name of Obligor to, in their respective discretion, take
any action and execute any instrument which they respectively may deem necessary
or advisable to accomplish the purposes of this Agreement, including, without
limitation, with respect to the Collateral:

         (a) filing one or more financing or continuation statements, and
amendments thereto, relative to all or any part of the Collateral without the
signature of Obligor where permitted by law; and

         (b) to ask, demand, collect, sue for, recover, compromise, receive and
give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral and to file any claims or take any action or
institute any proceedings which the Secured Party may deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
the rights of the Secured Party with respect to any of the Collateral, or the
rights and remedies under Section 7 hereof.

         The power of attorney granted pursuant to this Section 8.1 is coupled
with an interest and is irrevocable.

         8.2 Secured Party's Performance. If Obligor fails to perform any
covenant contained herein, the Secured Party may itself perform, or cause
performance of, such covenant, and Obligor shall pay for the expenses of the
Secured Party incurred in connection therewith.

         8.3 Secured Party's Duties. The powers conferred on the Secured Party
under this Agreement are solely to protect its interest in the Collateral and
the Pledged Shares and shall not impose any duty upon it to exercise any such
powers. Except for the safe custody of any Collateral in their possession and
the accounting for monies actually received by them hereunder, the Secured Party
shall have no duty as to any Collateral or as to the taking of any necessary
steps to preserve rights against prior parties or any other rights pertaining to
any Collateral or any Pledged Shares.

shall follow the directions regarding the release of the Collateral provided
therein. Upon any termination of the security interests granted hereby, all
rights to the Collateral and the Pledged Shares shall revert to Obligor to the

Broker Account Number  __-_______


                                    EXHIBIT A

                  FORM OF PLEDGED COLLATERAL ACCOUNT AGREEMENT

NOTE:  THIS AGREEMENT IS SUBJECT TO REVIEW AND ACCEPTANCE BY ________ ("BROKER")


TO:      Broker
         [address]

              1. Prior to the execution of this Pledged Collateral Account
    Agreement (the "Agreement"), the undersigned, Eurotech, Ltd. ("Assignor")
    and Woodward LLC ("Assignee") entered into Pledge and Security Agreement,
    dated as of December __, 2002 pursuant to which a security interest in
    certain rights and assets of Assignor is granted by Assignor to Assignee
    (the "Assignment"). In connection therewith, Assignor hereby instructs
    _________ Company ("Broker") to:

         a)       establish a cash security account, which is to be known as
                  "__________.", as Secured Party for__________________.,
                  Pledged Collateral A/C, Attn: _________________________ ("Cash
                  Account"); and

         b)       place the assets listed in Exhibit A, which is attached hereto
                  and made a part hereof, into the Cash Account for a period
                  through and until December 31, 2007, to be extended by mutual
                  consent.

              2. Assignor represents that Exhibit A is a correct listing of the
    assets to be held in the Cash Account (the "Collateral") and that it has
    received no notice of, and has no knowledge of, any other security interest
    in the Cash Account or Collateral. Broker will furnish all appropriate tax
    reporting information for the Cash Account to the Internal Revenue Service
    under Assignor's Tax Identification or Social Security Number.

              3. Assignor and Assignee consent and agree that instructions with
    regard to the Cash Account shall be given to Broker directly and shall be
    given only by Assignor, except as otherwise provided herein.

              4. Assignor may give instructions of any kind or character in
    regard to the Cash Account, oral or written, except that any instruction to
    Broker to deliver out of the Cash Account cash, securities and/or proceeds
    from the sale of or distributions on such securities, shall be made by a
    written instrument executed by either (a) an Authorized Officer of Assignor
    AND an Authorized Officer of Assignee or (b) an Authorized Officer of
    Assignee who shall certify in writing that an "Event of Default", as defined
    in the Assignment, exists as of the date thereof (it being understood and
    agreed that Broker shall have no duty or obligation whatsoever of any kind
    or character to determine whether an Event of Default exists). After
    receiving such notice of an Event of Default, if any, Broker shall not
    effect any trades or changes to investments with respect to the Collateral.
    Assignor and Assignee agree that, after notice of an Event of Default,
    Broker will proceed to liquidate on a best efforts basis the Cash Account or
    any portion thereof as may be directed in writing by Assignee. Assignee
    acknowledges and understands that there is no assurance that a liquid market
    exists for all of the Collateral. Further Assignee hereby agrees to
    indemnify and hold harmless Broker, its affiliates, officers, employees,

                                       13
<PAGE>

    agents, successors and assigns from and against any and all claims, causes
    of action, liabilities, lawsuits, demands and/or damages, including, without
    limitation, any and all court costs and reasonable attorney's fees, that may
    result by reason of Broker complying with such instructions by Assignee
    acting alone.

              5. For purposes of this Agreement, the term "Authorized Officer of
    Assignor" shall refer, collectively, to __________________, President and
    ________________. The term "Authorized Officer of Assignee" shall refer in
    the singular to_________ (who is, on the date hereof, a Director of
    Assignee). If the Assignor or the Assignee is a natural person then such
    term shall mean the Assignor or Assignee respectively and, if more than one
    natural person is the Assignee, such natural persons may act severally. An
    Authorized Officer shall be replaced by written notice by a senior officer
    of the party replacing said Authorized Officer, or by such other officer as
    Broker may approve, which approval shall not be unreasonably withheld.

              6. So long as this Agreement remains in effect, Assignee, as the
    Secured Party for the Cash Account, shall be entitled to receive any and all
    notices and statements of the Cash Account and Assignor, as an interested
    party, shall be entitled to receive duplicates of the trade confirmations
    and account statements of such Cash Account at the respective addresses
    listed below. Assignee agrees to forward promptly to Assignor, as beneficial
    owner of the Cash Account, all other documents relating to securities held
    in the Cash Account that are received by Assignee from Broker.

              7. Broker shall not be liable for any action taken or omitted by
    it in good faith with respect to the Cash Account and believed by Broker to
    be authorized or within its obligations hereunder. Broker may rely on any
    certificate, statement, request, agreement or other instrument it believes
    to be genuine and to have been signed or presented by a proper person.

              8. If conflicting demands are made or notices are served upon
    Broker with respect to this Agreement or Cash Account, or if Broker shall
    hold a good faith belief that the rights of a party to the Cash Account are
    not absolutely clear, the parties hereto agree that Broker shall be entitled
    to refuse to comply with any such notice or demand and to withhold and stop
    all further proceedings in the performance of this Agreement until (a) the
    rights of the adverse claimants have been finally adjudicated in a court
    having and assuming jurisdiction of the parties or the Cash Account or (b)
    all differences shall have been adjusted by mutual agreement of such
    claimants and Broker shall have been notified thereof in a writing signed by
    such claimants. Broker shall not be or become liable for damages or interest
    to Assignor or Assignee or to any other person for its failure to comply
    with such conflicting or adverse demands or notices. Broker may, but shall
    not be obligated to, file a suit in interpleader for a declaratory judgment
    for the purpose of having the respective rights of such claimants
    adjudicated, or may deposit the Collateral with a court of competent
    jurisdiction, in which event Assignor and Assignee, jointly and severally,
    agree to pay all reasonable costs, expenses and attorney's fees incurred by
    Broker in connection therewith. In the event that Broker shall deposit the
    Collateral with such court, Broker shall be fully released and discharged
    from any and all duties and obligations hereunder.

              9. Assignor and Assignee acknowledge and agree that Broker is not
    a party to any other agreement between them, that Broker is not bound by or
    subject to any terms thereof, and that Broker's only duties and
    responsibilities with respect to the Cash Account are those set forth
    herein. Assignor and Assignee acknowledge and agree that Broker has not
    arranged for and will not arrange for the extension or maintenance of any
    credit for the Cash Account.

              10. Assignor and Assignee acknowledge and agree that Broker shall
    not be liable to Assignee for any decrease in value of the investments in
    the Cash Account for any reason, including, by way of illustration and not
    limitation, liability for decreases in value resulting from transactions
    recommended by Broker or its employees or agents or from commission and/or
    other charges. Broker expressly has no obligation to advise either Assignor
    or Assignee of any decrease in the value of the Cash Account at any time.

              11. Assignor and Assignee acknowledge and agree that,
    notwithstanding anything to the contrary contained herein or in the
    Assignment, this Agreement shall not subordinate or release Broker's
    security interest in or lien on the Cash Account or impose or create any
    obligations or duties upon Broker greater than or in addition to the

                                       14
<PAGE>

    customary and usual obligations and duties of Broker to Assignor, as set
    forth in the Broker Customer Agreement executed by Assignor, and Broker may
    charge such fees, commissions, costs and interest, if applicable, in
    accordance with its customary practices, except and to the extent that
    Broker henceforth shall accept instructions in connection with the Cash
    Account as provided in this Agreement.

              12. Assignor and Assignee hereby agree to indemnify and hold
    harmless Broker, its affiliates, officers, employees, agents, successors and
    assigns from and against any and all claims, causes of action, liabilities,
    lawsuits, demands and/or damages, including, without limitation, any and all
    court costs and reasonable attorney's fees, in any way related to or arising
    out of or in connection with the Assignment, this Agreement and/or the Cash
    Account.

              13. Assignor, Assignee and Broker agree that any action instituted
    as a result of any controversy involving Broker or its employees or agents
    arising out of this Agreement, or as a result of any interpretation of any
    section thereof, or involving transactions in the Cash Account shall be
    brought before the arbitration facility of a self-regulatory organization
    with jurisdiction over Broker.

              14. This Agreement shall be binding upon and inure to the benefit
    of the successors and assigns of the respective parties hereto and shall be
    construed in accordance with the laws of the State of New York without
    regard to its conflict of laws principles and the rights and remedies of the
    parties shall be determined in accordance with such laws.

              15. Assignor and Assignee represent and warrant to Broker that the
    Agreement and Assignment are in compliance with applicable law, including,
    without limitation, the federal securities laws and regulations and any
    applicable Federal Reserve credit regulations.

              16. Assignor and Assignee acknowledge that this Agreement
    supplements Assignor's existing agreement(s) with Broker and, except as
    otherwise provided herein, that this Agreement in no way is intended to
    abridge any rights that Broker otherwise may have.

              17. Unless otherwise provided herein, any notice permitted or
    required hereunder from either Assignor or Assignee to Broker shall be in
    writing and shall be delivered personally or be mailed by certified or
    registered mail, return receipt requested, postage prepaid,
    to_____________________ New York, NY [ZIP] to_________, _________, NY [ZIP],
    with a copy to _______________and _____________________ at _______________,
    or to such other representative of Broker and address as provided in writing
    thereafter. Any such notice shall be effective upon receipt.

              18. Broker's duties and obligations under this Agreement shall
    terminate upon the delivery of written notice to Broker from Assignee that
    Assignor has satisfied the obligation underlying the Assignment or that the
    Assignment has been breached, expired or otherwise terminated.

              19. Broker may terminate its duties and obligations under this
    Agreement by giving Assignor and Assignee fifteen (15) days prior written
    notice of its intent (a) to transfer the Collateral to Assignee or its
    Designee, (b) to deliver the Collateral to another broker-dealer or
    financial institution if directed in a notice signed by Assignee and
    delivered to Broker prior to the end of such fifteen (15) day notice period,
    or (c) to otherwise terminate its Cash Account relationship with Assignor.
    If Assignee fails to direct Broker concerning the Collateral transfer,
    Broker may file an interpleader action or deposit the Collateral with a
    court as forth in this Agreement.

              20. This Agreement may be executed in any number of counterparts
    and by facsimile, each of which shall be an original and all of which taken
    together shall constitute one and the same instrument.
