                              W I T N E S S E T H:

                  WHEREAS, upon the terms and subject to the conditions of the
Common Stock Purchase Agreements, dated as of March 1, 2000 and April 24, 2000,
between the Initial Investor and the Company (the "Common Stock Purchase
Agreements"; terms not otherwise defined herein shall have the meanings ascribed
to them in the Common Stock Purchase Agreements), the Company has agreed to
issue and sell to the Initial Investor, 3,200,000 shares of Common Stock (the
"Initial Shares") , together with certain Repricing Rights ("Repricing Shares")
(collectively the "Shares") of the Company; and

                  WHEREAS, in connection with a previous sale of Common Stock to
the Initial Investor, the Company has heretofore issued a warrant (the "First
Warrant") to the Initial Investor to purchase an additional 200,000 shares of
Common Stock and, in the Common Stock Purchase Agreement, the Company agreed to
issue a further warrant (the "Warrant") to the Initial Investor to purchase
another 500,000 shares of Common Stock (the First Warrant and the Warrant being
sometimes referred to together as the "Warrants" and the shares purchasable upon
the exercise of the Warrants being sometimes referred to together as the
"Warrant Shares'); 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:

<PAGE>

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

                  (a) "Investor" means the Initial Investor and any permitted

                  (b) "Potential Material Event" means any of the following: (i)
the possession by the Company of material information not ripe for disclosure in

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 under
the Securities Act or any successor rule providing for offering securities on a

Shares and the Warrant Shares issued on the Initial Closing Date.

                  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 May 15, 2000 (the "Required
Filing Date") a Registration Statement on Form S-3 registering for resale by the
Investor a sufficient number of shares of Common Stock for the Initial Investors
to sell the Registrable Securities (or such lesser number as may be required by
the SEC, but in no event less than the sum of (i) the number of shares of the
Company's Common Stock previously sold to the Investor which are not longer
subject to repricing; (ii) two hundred (200%) percent of the aggregate number of
Initial Shares and the number of shares at the time of filing of the
Registration Statement (assuming for such purposes that the 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); (iii) two hundred (200%) percent of the aggregate number of shares of the
Company's Common Stock previously sold to the Investor which are subject to
repricing at the time of the filing of the Registration Statement; and (iv) the
Warrant Shares. 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) July15, 2000

                  (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).

                                      -3-
<PAGE>

                           (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 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.

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 occurs, (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 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

                                      -5-
<PAGE>

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;

                                      -6-
<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:

                                      -7-
<PAGE>

                  (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 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 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.

<PAGE>

                  (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 Company under the Securities Act and the Exchange Act;

                  (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 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; and

                  (d) The Company will, at the request of any holder of
Registrable Securities, upon receipt from such Holder of a certificate
certifying (i) that such holder has held such Registrable Securities for a
period of not less than (1) year, (ii) that such holder has not been an
affiliate (as defined in Rule 144) of the Company for more than the ninety (90)
days, and (iii) as to such other matters as may be appropriate in accordance
with such Rule, remove from the stock certificate representing such Registrable
Securities that portion of any restrictive legend which relates to the
registration provisions of the Securities Act, provided, however, that counsel
to the Investor may provide such instructions and opinion to the transfer agent
regarding the removal of the restrictive legend.

                  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. 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 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.

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.

                                                   SECURITIES PURCHASE AGREEMENT

                                 FORM OF WARRANT

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A "NO ACTION"
LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH
TRANSFER, A TRANSFER MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND
EXCHANGE COMMISSION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE
EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

EUROTECH, LTD.

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 April __, 2004 (the "Expiration Date"),
500,000 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
$10.00 per share (the "Exercise Price"), subject to further adjustment as set
forth in Section 6 hereof.

                  2. EXERCISE OF WARRANTS.

                           2.1 GENERAL. This Warrant is exercisable in whole or
in part at any time and from time to time at the Exercise Price per share of
Common Stock payable hereunder, payable in cash or by certified or official bank
check, or by "cashless exercise," by means of tendering this Warrant Certificate
to the Company to receive a number of shares of Common Stock equal in Market
Value to the difference between the aggregate Market Value of the shares of
Common Stock issuable upon exercise of this Warrant and the cash exercise price
thereof divided by the Market Value. Upon surrender of this Warrant Certificate
with the annexed Notice of Exercise Form duly executed (which Notice of Exercise
Form may be submitted either by delivery to the Company or by facsimile
transmission as provided in Section 8 hereof), together with payment of the
Exercise Price for the shares of Common Stock purchased, if applicable, the
Holder shall be entitled to receive a certificate or certificates for the shares
of Common Stock so purchased. For the purposes of this Section 2, "Market Value"
shall be an amount equal to the average closing ask price of a share of Common
Stock, as reported by Bloomberg, LP, for the five (5) trading days preceding the
Company's receipt of the Notice of Exercise Form duly executed multiplied by the
number of shares of Common Stock to be issued upon surrender of this Warrant
Certificate.

<PAGE>

                           2.2 LIMITATION ON EXERCISE. Notwithstanding the
provisions of this Warrant, the Securities Purchase Agreement (as defined below)
or of the other Transaction Agreements (as defined in the Securities Purchase
Agreement), in no event (except if the Company is in default hereunder or under
any of the Transaction Agreements, and the Holder has asserted such default in
writing and the applicability of this provision to such default) shall the
Holder be entitled to exercise this Warrant or shall the Company have the
obligation, to issue shares upon such exercise of all or any portion of this
Warrant to the extent that, after such conversion, the sum of (1) the number of
shares of Common Stock beneficially owned by the Holder and its affiliates
(other than shares of Common Stock which may be deemed beneficially owned
through the ownership of the unconverted portion of the Preferred Stock or
unexercised portion of the Warrants), and (2) the number of shares of Common
Stock issuable upon the conversion of the Preferred Stock or exercise of the
Warrants with respect to which the determination of this proviso is being made,
would result in beneficial ownership by the Holder and its affiliates of more
than 9.99% of the outstanding shares of Common Stock (after taking into account
the shares to be issued to the Holder upon such conversion or exercise). For
purposes of the proviso to the immediately preceding sentence, beneficial
ownership shall be determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "1934 Act"), except as otherwise provided
in clause (1) of such sentence. The Holder, by its acceptance of this Warrant,
further agrees that if the Holder transfers or assigns any of the Warrants to a
party who or which would not be considered such an affiliate, such assignment
shall be made subject to the transferee's or assignee's specific agreement to be
bound by the provisions of this Section 2.2 as if such transferee or assignee
were the original Holder hereof.

                  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

                                       2
<PAGE>

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.

                           6.3 ADJUSTMENT FOR SPIN OFF. If, for any reason,
prior to the exercise of this Warrant in full, the Company spins off or
otherwise divests itself of a part of its business or operations or disposes all
or of a part of its assets in a transaction (the "Spin Off") in which the
Company does not receive compensation for such business, operations or assets,
but causes securities of another entity (the "Spin Off Securities") to be issued
to security holders of the Company, then

                  (a) the Company shall cause (i) to be reserved Spin Off
         Securities equal to the number thereof which would have been issued to
         the Holder had all of the Holder's unexercised Warrants outstanding on
         the record date (the "Record Date") for determining the amount and
         number of Spin Off Securities to be issued to security holders of the
         Company (the "Outstanding Warrants") been exercised as of the close of
         business on the trading day immediately before the Record Date (the
         "Reserved Spin Off Shares"), and (ii) to be issued to the Holder on the
         exercise of all or any of the Outstanding Warrants, such amount of the
         Reserved Spin Off Shares equal to (x) the Reserved Spin Off Shares
         multiplied by (y) a fraction, of which (I) the numerator is the amount
         of the Outstanding Warrants then being exercised, and (II) the
         denominator is the amount of the Outstanding Warrants; and

                  (b) the Exercise Price on the Outstanding Warrants shall be
         adjusted immediately after consummation of the Spin Off by multiplying
         the Exercise Price by a fraction (if, but only if, such fraction is
         less than 1.0), the numerator of which is the numerator of which is the
         Average Market Price of the Common Stock for the five (5) trading days
         immediately following the fifth trading day after the Record Date, and
         the denominator of which is the Average Market Price of the Common
         Stock on the five (5) trading days immediately following the fifth
         trading day after the Record Date, and the denominator of which is the
         Average Market Price of the Common Stock on the five (5) trading days
         immediately preceding the Record Date; and such adjusted Exercise Price
         shall be deemed to be the Exercise Price with respect to the
         Outstanding Warrants after the Record Date.

For the purposes of this Section 6.3, the "Average Market Price of the Common
Stock" shall mean, for the relevant period, (x) the average closing bid price of

                                       3
<PAGE>

a share of Common Stock, as reported by Bloomberg, LP or, if not so reported, as
reported on the over-the-counter market or (y) if the Common Stock is listed on
a stock exchange, the closing price on such exchange on the date indicated in
the relevant provision hereof, as reported in The Wall Street Journal.

                  7. TRANSFER TO COMPLY WITH THE SECURITIES ACT; REGISTRATION
                     RIGHTS.

                  (a) This Warrant has not been registered under the Securities
Act of 1933, as amended, (the "Act") and has been issued to the Holder for
investment and not with a view to the distribution of either the Warrant or the
Warrant Shares. Neither this Warrant nor any of the Warrant Shares or any other
security issued or issuable upon exercise of this Warrant may be sold,
transferred, pledged or hypothecated in the absence of an effective registration
statement under the Act relating to such security or an opinion of counsel
satisfactory to the Company that registration is not required under the Act.
Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.

                  (b) The Company hereby grants to the Holder registration
rights with respect to the Warrant Shares in accordance with a Registration
Rights Agreement between the Company and Holder of even date herewith..

                  (c) In addition to the registration rights referred to in the
preceding provisions of Section (b), effective after the expiration of the
effectiveness of the Registration Statement as contemplated by this Warrant, the
Holder shall have demand piggy-back registration rights with respect to the
Warrant Shares then held by the Holder or then subject to issuance upon exercise
of this Warrant (collectively, the "Remaining Warrant Shares"), subject to the
conditions set forth below. If, at any time after the Registration Statement has
ceased to be effective, the Company participates (whether voluntarily or by
reason of an obligation to a third party) in the registration of any shares of
the Company's stock, the Company shall give written notice thereof to the Holder
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.

                  8. NOTICES. Any notice or other communication required or
permitted hereunder shall be in writing and shall be delivered personally,
telegraphed, telexed, sent by facsimile transmission or sent by certified,
