                          COMMON STOCK PURCHASE WARRANT

            1. Issuance. In consideration of good and valuable consideration,
the receipt of which is hereby acknowledged by, Eurotech, LTD. a District of
Columbia corporation (the "Company"), Woodward LLC or registered assigns (the
"Holder") is hereby granted the right to purchase at any time until 5:00 P.M.,
New York City time, on December 31,2004 (the "Expiration Date"), 200,000 fully
paid and nonassessable shares of the Company's Common Stock, par value $.00025
per share (the "Common Stock") at an initial exercise price of $3.125 per share
(the "Exercise 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 upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

            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 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
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 may 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.

and the Holder shall have the right, exercisable within ten (10) business days
after receipt of such notice, to demand inclusion of all or a portion of the
Holder's Remaining Warrant Shares in such registration statement.

                          REGISTRATION RIGHTS AGREEMENT

            THIS REGISTRATION RIGHTS AGREEMENT, dated as of December 31, 1999
(this "Agreement"), is made by and between EUROTECH, LTD., a District of
Columbia corporation, with headquarters located at 1216 16th Street, N.W.,
Washington, D.C. 20036 (the "Company"), and each entity named on a signature
page hereto (each, an "Initial Investor") (each agreement with an Initial
Investor being deemed a separate and independent agreement between the Company
and such Initial Investor, except that each Initial Investor acknowledges and
consents to the rights granted to each other Initial Investor under such
agreement).

                              W I T N E S S E T H:

            WHEREAS, upon the terms and subject to the conditions of the Common
Stock Purchase Agreement, dated as of December 31, 1999, between the Initial
Investor and the Company (the "Common Stock Purchase Agreement"; terms not
otherwise defined herein shall have the meanings ascribed to them in the Common
Stock Purchase Agreement), the Company has agreed to issue and sell to the
Initial Investor, 1,882,353 shares of Common Stock (the "Initial Shares") ,
together with certain Repricing Rights ("Repricing Shares") (collectively the
"Shares") of the Company; and

            WHEREAS, the Company has agreed to issue the Warrants to the Initial
Investor in connection with the issuance of the Common Stock; and

            WHEREAS, to induce the Initial Investor to execute and deliver the
Common Stock 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 Common Shares, the Repricing Shares and
the 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 agree as follows:

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

            (a) "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 and who holds Shares or Warrants.

            (b) "Potential Material Event" means any of the following: (i) the
possession by the Company of material information not ripe for disclosure in a
registration statement, which shall be evidenced by determinations in good faith
by the Board of Directors of the Company that disclosure of such information in
the registration statement would be detrimental to the business and affairs of
the Company; or (ii) any material engagement or activity by the Company which
would, in the good faith determination of the Board of Directors of the Company,
be adversely affected by disclosure in a registration statement at such time,
which determination shall be accompanied by a good faith determination by the
Board of Directors of the Company that the registration statement would be
materially misleading absent the inclusion of such information.

            (c) "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
<PAGE>

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").

            (d) "Registrable Securities" means the Shares, the Repricing Shares
and the Warrant Shares issued on the Initial Closing Date and the Other
Registrable Securities as set forth in Schedule 5 hereto.

            (e) "Registration Statement" means a registration statement of the
Company under the Securities Act, or an amendment to an existing registration
statement.

            2. Registration.

            (a) Mandatory Registration.

                  The Company shall prepare and file with the SEC, as soon as
possible after the Initial Closing and no later than a date (the "Required
Filing Date") which is thirty (30) days following the Initial Closing Date,
either a Registration Statement on Form S-1 or an amendment to an existing
Registration Statement, in either event registering for resale by the Investor a
sufficient number of shares of Common Stock for the Initial Investors to sell
the Registrable Securities (or such lesser number as may be required by the SEC
(assuming for such purposes that such Warrants had been eligible to be exercised
and had been exercised in accordance with their terms, whether or not such
eligibility or exercise had in fact occurred as of such date). The Registration
Statement (X) shall also 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 repricing of the Common Stock
and the exercise of the Warrants to prevent dilution resulting from stock splits
or stock dividends. The Company will use its reasonable best efforts to cause
such Registration Statement to be declared effective on a date (a "Required
Effective Date") which is no later than is the earlier of (Y) five (5) days
after notice by the SEC that it may be declared effective or (Z) ninety (90)
days after the Initial Closing Date or thirty (30) days after the relevant
Additional Closing Date, as the case may be.

            (b) Payments by the Company.

                  (i) If the Registration Statement covering the Registrable
Securities is not filed in proper form with the SEC by the Required Filing Date,
the Company will make payment to the Initial Investor in such amounts and at
such times as shall be determined pursuant to this Section 2(b).

                  (ii) If the Registration Statement covering the Registrable
Securities is not effective by thirty (30) days after the relevant Required
Effective Date or if the Investor is restricted from making sales of Registrable
Securities covered by a previously effective Registration Statement at any time
(the date such restriction commences, a "Restricted Sale Date") after the
Effective Date other than during a Suspension Period (as defined below), then
the Company will make payments to the Initial Investor in such amounts and at
such times as shall be determined pursuant to this Section 2(b).

                  (iii) The amount (the "Periodic Amount") to be paid by the
Company to the Initial Investor shall be determined as of each Computation Date
(as defined below) and such amount shall be equal to the Periodic Amount
Percentage (as defined below) of the Purchase Price for all the Initial Shares
for the period from the date following the relevant Required Filing Date,
Required Effective Date or Restricted Sale Date, as the case may be, to the
first relevant Computation Date, and thereafter to each subsequent Computation
Date. The "Periodic Amount Percentage" means (A) two percent (2%) of the
Purchase Price for the period from the date following the relevant Required
Filing Date, Required Effective Date or Restricted Sale Date, as the case may
be, to the first relevant Computation Date (prorated on a daily basis if such
period is less than thirty [30] days), and (B) two percent (2%) of the Purchase
Price to each Computation Date thereafter (prorated on a daily basis if such
period is less than thirty [30] days). By way of illustration and not in
limitation of the foregoing, if the Registration Statement for the Registrable
Securities relating to the Common Stock and Warrants issued on the Initial
Closing Date is timely filed

                                       2
<PAGE>

but is not declared effective until one hundred sixty-five (165) days after the
Initial Closing Date, the Periodic Amount will aggregate six percent (6%) of the
Purchase Price of the Initial Common Stock (4% for days 90-150, plus 2% for days
151-165).

                  (iv) Each Periodic Amount will be payable by the Company in
cash or other immediately available funds to the Investor monthly, without
requiring demand therefor by the Investor.

                  (v) The parties acknowledge that the damages which may be
incurred by the Investor if the Registration Statement is not filed by the
Required Filing Date or if the Registration Statement has not been declared
effective by a Required Effective Date, including if the right to sell
Registrable Securities under a previously effective Registration Statement is
suspended, may be difficult to ascertain. The parties agree that the Periodic
Amounts represent a reasonable estimate on the part of the parties, as of the
date of this Agreement, of the amount of such damages.

                  (vi) Notwithstanding the foregoing, the amounts payable by the
Company pursuant to this provision shall not be payable to the extent any delay
in the effectiveness of the Registration Statement occurs because of an act of,
or a failure to act or to act timely by the Initial Investor or its counsel, or
in the event all of the Registrable Securities may be sold pursuant to Rule 144
or another available exemption under the Act.

                  (vii) "Computation Date" means (A) the date which is the
earlier of (1) thirty (30) days after the Required Filing Date, any relevant
Required Effective Date or a Restricted Sale Date, as the case may be, or (2)
the date after the Required Filing Date, such Required Effective Date or
Restricted Sale Date on which the Registration Statement is filed (with respect
to payments due as contemplated by Section 2(b)(i) hereof) or is declared
effective or has its restrictions removed (with respect to payments due as
contemplated by Section 2(b)(ii) hereof), as the case may be, and (B) each date
which is the earlier of (1) thirty (30) days after the previous Computation Date
or (2) the date after the previous Computation Date on which the Registration
Statement is filed (with respect to payments due as contemplated by Section
2(b)(i) hereof) or is declared effective or has its restrictions removed (with
respect to payments due as contemplated by Section 2(b)(ii) hereof), as the case
may be.

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

            (a) Prepare promptly, and file with the SEC by the Required Filing
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
reasonable best efforts to cause such Registration Statement relating to
Registrable Securities to become effective by the Required Effective Date and
keep the Registration Statement effective at all times during the period (the
"Registration Period") continuing until the earliest of (i) the date that is two
(2) years after the last day of the calendar month following the month in which
the closing at the end of the Final Repricing Period, (ii) the date when the
Investors may sell all Registrable Securities under Rule 144 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 Statement 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

                                       3
<PAGE>

review the Registration Statement and all amendments and supplements thereto a
reasonable period of time (but not less than three (3) business days) prior to
their filing with the SEC, and not file any document in a form to which such
counsel reasonably objects.

            (d) Notify each Investor, such Investor's legal counsel identified
to the Company (which, until further notice, shall be deemed to be Krieger &
Prager, ATTN: Samuel Krieger, Esq.; each, an "Investor's Counsel") (and, in the
case of (i)(A) below, not less than five (5) days prior to such filing) and (if
requested by any such Person) confirm such notice in writing no later than one
(1) business day following the day (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) whenever the SEC notifies the Company whether there will be a
"review" of such Registration Statement; (C) whenever the Company receives (or a
representative of the Company receives on its behalf) any oral or written
comments from the SEC respect of a Registration Statement (copies or, in the
case of oral comments, summaries of such comments shall be promptly furnished by
the Company to the Investors); and (D) with respect to the Registration
Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the SEC or any other Federal or state governmental
authority for amendments or supplements to the Registration Statement or
Prospectus or for additional information; (iii) of the issuance by the SEC of
any stop order suspending the effectiveness of the Registration Statement
covering any or all of the Registrable Securities or the initiation of any
Proceedings for that purpose; (iv) if at any time any of the representations or
warranties of the Company contained in any agreement (including any underwriting
agreement) contemplated hereby ceases to be true and correct in all material
respects; (v) of the receipt by the Company of any notification with respect to
the suspension of the qualification or exemption from qualification of any of
the Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose; and (vi) of the occurrence of
any event that to the best knowledge of the Company makes any statement made in
the Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. In addition, the Company shall furnish the Investors with
copies of all intended written responses to the comments contemplated in clause
(C) of this Section 3(d) not later than one (1) business day in advance of the
filing of such responses with the SEC so that the Investors shall have the
opportunity to comment thereon.

            (e) Furnish to each Investor and such Investor's Counsel (i)
promptly after the same is prepared and publicly distributed, filed with the
SEC, or received by the Company, two (2) copies 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;

            (f) As promptly as practicable after becoming aware thereof, 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;

            (g) As promptly as practicable after becoming aware thereof, notify
each Investor who holds Registrable Securities being sold (or, in the event of
an underwritten offering, the managing underwriters) 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;

                                       4
<PAGE>

            (h) Notwithstanding the foregoing, if at any time or from time to
time after the date of effectiveness of the Registration Statement, the Company
notifies the Investors in writing of the existence of a Potential Material
Event, the Investors shall not offer or sell any Registrable Securities, or
engage in any other transaction involving or relating to the Registrable
Securities, from the time of the giving of notice with respect to a Potential
Material Event until such Investor receives written notice from the Company that
such Potential Material Event either has been disclosed to the public or no
longer constitutes a Potential Material Event; provided, however, that the
Company may not so suspend the right to such holders of Registrable Securities
for more than two twenty (20) day periods in the aggregate during any 12-month
period ("Suspension Period") with at least a ten (10) business day interval
between such periods, during the periods the Registration Statement is required
to be in effect;

            (i) Use its reasonable efforts to secure and maintain the
designation of all the Registrable Securities covered by the Registration
Statement on the "OTC Bulletin Board Market" of the National Association of
Securities Dealers Automated Quotation System ("NASDAQ") 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 Bulletin Board Market; 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;

            (j) Provide a transfer agent for the Registrable Securities not
later than the effective date of the Registration Statement;

            (k) Cooperate with the Investors 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; and

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

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

            (a) It shall be a condition precedent to the obligations of the
Company to complete the registration pursuant to this Agreement with respect to
the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of the Registrable
Securities held by it, as shall be reasonably required to effect the
registration of such Registrable Securities and shall execute such documents in
connection with such registration as the Company may reasonably request. At
least ten (10) 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
need not file the Registration Statement until receiving the response of such
Non-Responsive Investor;

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

            (c) Each Investor agrees that, upon receipt of any notice from the
Company of the happening

                                       5
<PAGE>

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).

            5. Expenses of Registration. (a) All reasonable expenses (other than
underwriting discounts and commissions of the Investor) 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 and a fee for a single counsel for the Investors (as a group and not
individually) not exceeding $3,500 for the Registration Statement covering the
Registrable Securities applicable to the Common Stock and Warrants issued on the
Closing Date shall be borne by the Company.

            (b) Except as otherwise provided for in Schedule 5 hereto, neither
the Company nor any of its subsidiaries has, as of the date hereof, nor shall
the Company nor any of its subsidiaries, on or after the date of this Agreement,
enter into any agreement with respect to its securities that is inconsistent
with the rights granted to the Investors in this Agreement or otherwise
conflicts with the provisions hereof. Except as otherwise provided for in
Schedule 5 neither the Company nor any of its subsidiaries has previously
entered into any agreement granting any registration rights with respect to any
of its securities to any Person. Except as otherwise provided for in this
Section 5, and without limiting the generality of the foregoing, without the
written consent of the Investors holding a majority of the Registrable
Securities, the Company shall not grant to any person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Investors set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement and the other Transaction
Agreements.

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

            (a) To the extent permitted by law, the Company will indemnify 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 Party"), 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"). Subject to clause (b) of this Section 6, 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 Party 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(c) hereof; (II) be available to the extent such Claim is based on a failure of
the Investor to deliver or

                                       6
<PAGE>

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 will indemnify the Company and its
officers, directors and agents (each, an "Indemnified Party") 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 Party and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.

            (b) Promptly after receipt by an Indemnified Party under this
Section 6 of notice of the commencement of any action (including any
governmental action), such 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, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Party, as
the case may be. In case any such action is brought against any Indemnified
Party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate in, and, to the extent that
it may wish, jointly with any other indemnifying party similarly notified,
assume the defense thereof, subject to the provisions herein stated and after
notice from the indemnifying party to such Indemnified Party of its election so
to assume the defense thereof, the indemnifying party will not be liable to such
Indemnified Party under this Section 6 for any legal or other reasonable
out-of-pocket expenses subsequently incurred by such Indemnified Party in
connection with the defense thereof other than reasonable costs of
investigation, unless the indemnifying party shall not pursue the action of its
final conclusion. The Indemnified Party shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and reasonable out-of-pocket expenses of such counsel shall not be at the
expense of the indemnifying party if the indemnifying party has assumed the
defense of the action with counsel reasonably satisfactory to the Indemnified
Party. 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 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

                                       7
<PAGE>

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 unexercised Warrant) 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. 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(c) hereof arising from such delay.

            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. Rule 144 Requirements. The Company shall make publicly available
and available to the Investor of Registrable Securities, pursuant to Rule 144 of
the Commission under the Securities Act, such information as shall be necessary
to enable the Investors of Registrable Securities to make sales of Registrable
Securities pursuant to that Rule. The Company will furnish to any Investor of
Registrable Securities, upon request made by such Investor at any time, a
written statement signed by the Company, addressed to such Investor, describing
briefly the action the Company has taken or proposes to take to comply with the
current public information requirements of Rule 144. The Company will, at the
request of any Investor of Registrable Securities, upon receipt from such
Investor of a certificate certifying (i) that such Investor has held such
Registrable Securities for a period of not less than one (1) year, (ii) that
such Investor has not been an affiliate (as defined in Rule 144) of the Company
for more than the ninety (90) preceding days, and (iii) as to such other matters
as may be appropriate in accordance with such Rule, remove from the stock
certificates representing such Registrable Securities that portion of any
restrictive legend which relates to the registration provisions of the
Securities Act, provided, however, counsel to Investor may provide such
instructions and opinion to the transfer agent regarding the removal of the
restrictive legend.

            12. Miscellaneous.

            (a) A person or entity is deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

            (b) Notices required or permitted to be given hereunder shall be
given in the manner

                                       8
<PAGE>

contemplated by the Agreement, (i) if to the Company or to the Initial Investor,
to their respective address contemplated by the Agreement, and (iii) if to any
other Investor, at such address as such Investor shall have provided in writing
to the Company, or at such other address as each such party furnishes by notice
given in accordance with this Section 12(b).

            (c) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

            (d) This Agreement shall be governed by and interpreted in
accordance with the laws of the State of Delaware for contracts to be wholly
performed in such state and without giving effect to the principles thereof
regarding the conflict of laws. Each of the parties consents to the jurisdiction
of the federal courts whose districts encompass any part of the City of
Wilmington or the state courts of the State of Delaware sitting in the City of
Wilmington 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. To the extent determined by such court, the
Company shall reimburse the Purchaser for any reasonable legal fees and
disbursements incurred by the Purchaser in enforcement of or protection of any
of its rights under this Agreement.

            (e) If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement or the
validity or enforceability of this Agreement in any other jurisdiction.

            (f) Subject to the requirements of Section 9 hereof, this Agreement
shall inure to the benefit of and be binding upon the successors and assigns of
each of the parties hereto.

            (g) All pronouns and any variations thereof refer to the masculine,
feminine or neuter, singular or plural, as the context may require.

            (h) The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning thereof.

            (i) This Agreement may be executed in one or more counterparts, each
of which shall be deemed an original but all of which shall constitute one and
the same agreement. This Agreement, once executed by a party, may be delivered
to the other party hereto by telephone line facsimile transmission of a copy of
this Agreement bearing the signature of the party so delivering this Agreement.

            (j) The Company acknowledges that any failure by the Company to
perform its obligations under Section 3(a) hereof, or any delay in such
performance, could result in loss to the Investors, and the Company agrees that,
in addition to any other liability the Company may have by reason of such
failure or delay, the Company shall be liable for all direct damages caused by
any such failure or delay, unless the same is the result of force majeure.
Neither party shall be liable for consequential damages.

            (k) This Agreement constitutes the entire agreement among the
parties hereto with respect to the subject matter hereof. There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein. This Agreement supersedes all prior agreements and
understandings among the parties hereto with respect to the subject matter
hereof. This Agreement may be amended only by an instrument in writing signed by
the party to be charged with enforcement thereof.
