                                 IV. CONVERSION

         A. CONVERSION AT THE OPTION OF THE HOLDER. Each Holder of shares of
Designated Preferred Stock may, at any time after the Closing Date and from time
to time thereafter, convert (an "OPTIONAL CONVERSION") each of its shares of
Designated Preferred Stock into a number of fully paid and nonassessable shares

                     STATED VALUE OF SHARES TO BE CONVERTED
                 -----------------------------------------------
                           APPLICABLE CONVERSION PRICE

         B. MECHANICS OF CONVERSION. To effect a conversion of shares of the
Designated Preferred Stock, the Holder must deliver or fax a Notice of
Conversion in the form attached hereto as Exhibit A ("NOTICE OF CONVERSION") to
the Company (to the attention of the President or such other officer as may
identified by notice given by the Company to the Holder from time to time) as
provided in this Paragraph. The Notice of Conversion shall be executed by the
Holder of one or more shares of Designated Preferred Stock and shall evidence
such Holder's intention to convert all or a portion of such shares. The date of
conversion (the "CONVERSION DATE") shall be deemed to be the date on which the
Holder faxes or otherwise delivers a Notice of Conversion to the Company.



<PAGE>

                  1. DELIVERY OF COMMON STOCK UPON CONVERSION. The Conversion
         Certificates will be delivered to the Converting Holder at the address
         specified in the Notice of Conversion, via express courier, by
         electronic transfer or otherwise, within five (5) business days (such
         fifth business day, a "DELIVERY DATE") after the date on which the
         Notice of Conversion is delivered to the Company as contemplated in
         this Paragraph.

                  2. TAXES. The Company shall pay any and all taxes which may be
         imposed upon the Company with respect to the issuance and delivery of
         the shares of Common Stock upon the conversion of the Designated
         Preferred Stock other than transfer taxes due upon conversion, if such
         Holder has transferred to another party the Designated Preferred Stock
         or the right to receive Common Stock upon the Holder's conversion
         thereof or any or income taxes due on the part of the Holder. The
         Company shall have the right to withhold any taxes as required by the
         United States federal or state tax laws.

                  3. NO FRACTIONAL SHARES. If any conversion of Designated
         Preferred Stock would result in the issuance of a fractional share of
         Common Stock, such fractional share shall be disregarded and the number
         of shares of Common Stock issuable upon conversion of the Designated
         Preferred Stock shall be rounded up or down to the nearest whole share,
         it being understood that .5 of one share shall be rounded up to the
         next highest share.

                  4. CONVERSION DISPUTES. In the case of any dispute with
         respect to a conversion, the Company shall promptly issue such number
         of shares of Common Stock as are not disputed in accordance with
         Paragraph A of this Article IV. If such dispute involves the
         calculation of the Conversion Price, the Company shall first discuss
         such discrepancy with the Converting Holder. If the Company and the
         Converting Holder are unable to agree upon the Conversion Price
         calculation, the Company shall promptly submit the disputed
         calculations to independent auditors to be selected by the Holder
         (unless the Holders and the Company mutually agree to a different
         firm). The auditors, at the expense of the party or parties in error
         (as determined by the auditors), shall audit the calculations and
         notify the Company and the Holder of the results within five (5)
         business days following the date it receives the disputed calculations.
         The auditor's calculation shall be deemed conclusive, absent manifest
         error. The Company shall then issue the appropriate number of shares of
         Common Stock in accordance with Paragraph A of Article IV above.

                  5. DELAY IN DELIVERING CONVERSION CERTIFICATES. The Company
         understands that a delay in the delivery of the Conversion Certificates
         beyond the Delivery Date could result in economic loss to a Holder. As
         compensation to a Holder for such loss, the Company agrees if there is
         a delay in the delivery of the Conversion Certificates (as adjusted in
         accordance with this provision) so that such Conversion Certificates
         are not received within five (5) business days after the Delivery Date,
         to pay late payments to such Holder for late delivery of Conversion



<PAGE>

         Certificates in accordance with the following schedule (where "No.
         Business Days Late" is defined as the number of business days beyond
         five (5) business days after the Delivery Date):

         No. Business Days              Late Payment For Each $10,000 of
               Late                       Stated Value Being Converted

                     2                                         $200
                     3                                         $300
                     4                                         $400
                     5                                         $500

                     7                                         $700
                     8                                         $800
                     9                                         $900
                    10                                       $1,000
                   >10               $1,000 +$200 for each Business
                                            Day Late beyond 10 days

         The Company shall pay any payments incurred under this Paragraph in
         immediately available funds upon demand. Nothing herein shall limit the
         Holder's right to pursue actual damages for the Company's failure to
         issue and deliver the Conversion Certificates to the Holder within a
         reasonable time. Furthermore, in addition to any other remedies which
         may be available to a Holder, in the event that the Company fails for
         any reason to effect delivery of such Conversion Certificates within
         five (5) business days after the Delivery Date, the Converting Holder
         will be entitled to revoke the relevant Notice of Conversion by
         delivering a notice to such effect to the Company whereupon the Company
         and the Converting Holder shall each be restored to their respective
         positions immediately prior to delivery of such Notice of Conversion;
         PROVIDED, HOWEVER, that any payments contemplated by this Paragraph
         B(5) of this Article IV which have accrued through the date of such
         revocation notice shall remain due and owing to the Converting Holder
         notwithstanding such revocation.

                  6. BUY-IN. If, by the relevant Delivery Date, the Company
         fails for any reason to deliver the Conversion Certificates and after
         such Delivery Date, the Holder of the Designated Preferred Stock being
         converted (a "CONVERTING HOLDER") purchases, in an arm's-length open
         market transaction or otherwise, shares of Common Stock (the "COVERING
         SHARES") in order to make delivery in satisfaction of a sale of Common
         Stock by the Converting Holder (the "SOLD SHARES"), which delivery such
         Converting Holder anticipated to make using the shares to be issued
         upon such conversion (a "BUY-IN"), the Converting Holder shall have the



<PAGE>

         right to require the Company to pay to the Converting Holder, in
         addition to and not in lieu of the amounts due under Paragraph B(5) of
         Article IV hereof (and in addition to all other amounts contemplated in
         other provisions of the other agreements between the Company and the
         Holder, and not in lieu of any such other amounts), the Buy-In
         Adjustment Amount. The Company shall pay the Buy-In Adjustment Amount
         to the Converting Holder in immediately available funds immediately
         upon demand by the Converting Holder.

                  7. DWAC CERTIFICATE DELIVERY. In lieu of delivering physical
         certificates representing the Common Stock issuable upon conversion,
         provided the Company's transfer agent is participating in the
         Depository Trust Company ("DTC") Fast Automated Securities Transfer
         program, upon request of a Converting Holder and his/her compliance
         with the provisions contained in this paragraph, so long as the
         certificates therefor do not bear a legend and the Converting Holder
         thereof is not obligated to return such certificate for the placement
         of a legend thereon, the Company shall use its best efforts to cause
         its transfer agent to electronically transmit the Common Stock issuable
         upon conversion to the Converting Holder by crediting the account of
         Converting Holder's prime broker with DTC through its Deposit
         Withdrawal Agent Commission system.

                  8. CONVERSION OBLIGATIONS AND DEFAULT. If, at any time the
         Company challenges, disputes or denies the right of a Holder of
         Designated Preferred Stock to effect a conversion of the Designated
         Preferred Stock into Common Stock or otherwise dishonors or rejects any
         Notice of Conversion delivered in accordance with the terms of this
         Certificate of Designations (subject to the provisions of Paragraph
         B(4) of this Article IV with respect to certain disputes relating to
         calculations of the number of shares to be issued), then such Holder
         shall have the right, by written notice to the Company, to require the
         Company to redeem each share of Designated Preferred Stock for which a
         Notice of Conversion has been refused pursuant to this Paragraph B(8)
         for cash, at an amount per share equal to the Holder Redemption Price.

                  9. CONVERSION IN BANKRUPTCY. The Holder of any Designated
         Preferred Stock shall be entitled to exercise its conversion privilege
         with respect to the Designated Preferred Stock notwithstanding the
         commencement of any case under 11 U.S.C. ss.101 ET SEQ. (the
         "BANKRUPTCY CODE"). In the event the Company is a debtor under the
         Bankruptcy Code, the Company hereby waives, to the fullest extent
         permitted, any rights to relief it may have under 11 U.S.C. ss.362 in
         respect of such Holder's right to convert the Designated Preferred
         Stock. The Company agrees, without cost or expense to such Holder, to
         take or to consent to any and all action necessary to effectuate relief
         under 11 U.S.C. ss.362.

                  V. RESERVATION OF SHARES OF COMMON STOCK

         A. RESERVED AMOUNT. Upon the initial issuance of the shares of
Designated Preferred Stock, the Company shall reserve, out of the authorized but
unissued shares of Common Stock, 50,000,000 shares of Common Stock (the
"RESERVED AMOUNT"; subject to adjustment as provided below) for issuance upon
conversion of the Designated Preferred Stock. Thereafter the number of
authorized but unissued shares of Common Stock so reserved shall cover at least
a number of shares equal to the sum of two hundred percent (200%) of (A) the



<PAGE>

number of shares of Common Stock as would then be issuable upon a conversion in
full of the then outstanding Designated Preferred Stock, and (B) the number of
shares of Common Stock as would be issuable as payment of dividends on the
Designated Preferred Stock. The Reserved Amount shall be adjusted as and when
the Conversion Price is adjusted pursuant to Article VIII hereof. The Reserved
Amount shall be allocated to the holders of Designated Preferred Stock as
provided in Article XI Paragraph D.

                                 VI. REDEMPTION

         A. REDEMPTION BY THE COMPANY.

         1. Notwithstanding any other provision hereof to the contrary, at any
time the Company shall have the right to redeem all or any portion of the then
outstanding principal amount of the Designated Preferred Stock then held by the
Holder (a "COMPANY REDEMPTION") in cash for an amount (the "COMPANY REDEMPTION
AMOUNT") equal to Redemption Price.

         2. If the Company elects to make a Company Redemption, the Company
shall give written notice of such redemption to the Holder (the "COMPANY NOTICE
OF REDEMPTION"). The date on which the Company shall pay the Company Redemption
Amount (the "COMPANY REDEMPTION PAYMENT DATE") shall be no fewer than five (5)
business days and no later than ten (10) business days after the Company Notice
of Redemption is given by the Company.

         3. Upon receipt of the Company Notice of Redemption, the Holder's right
to effect a Conversion with respect to shares of Designated Preferred Stock
being specified as being redeemed in such Company Notice of Redemption shall
continue at the until the Company Redemption Payment Date.

         4. Restriction on Redemption. The Company shall not be entitled to send
Company Notice of Redemption under Section (2) hereof unless it has:

A.       (i)      The full amount of the applicable Redemption Price in cash or
                  cash equivalents, available in a demand or other immediately
                  available account in one or more banks or similar financial
                  institutions;

         (ii)     Immediately available credit facilities in the full amount of
                  the applicable Redemption Price with one or more banks or
                  similar financial institutions;

         (iii)    An agreement with a standby underwriter willing to purchase
                  from the Company a sufficient number of shares of stock to
                  provide proceeds equal to the applicable Redemption Price; or

         (iv)     A combination of the items set forth in (i), (ii) and (iii)
                  above, aggregating the full amount of the applicable
                  Redemption Price.

B. Certified to the Holder, in writing, that it is not aware of the existence or
imminent existence or likelihood of any event described in Article VIII. A.



<PAGE>

         5. At the election of the Holder at any time prior to the date on which
the Company pays the Company Redemption Amount to the Holder, the Holder shall
have the right to convert the Designated Preferred Stock as if such Company
Notice of Redemption had never been given.

                           VII. LIQUIDATION PREFERENCE

         A. LIQUIDATION, DISSOLUTION, WINDING UP OR CERTAIN MERGERS OR
CONSOLIDATIONS. If the Company shall adopt a plan of liquidation or of
dissolution, or commence a voluntary case under the federal bankruptcy laws or
any other applicable state or federal bankruptcy, insolvency or similar law, or
consent to the entry of an order for relief in any involuntary case under such
law or to the appointment of a receiver, liquidator, assignee, custodian,
trustee or sequestrator (or similar official) of the Company or of any
substantial part of its property, or make an assignment for the benefit of its
creditors, or admit in writing its inability to pay its debts generally as they
become due and on account of such event the Company shall liquidate, dissolve or
wind up, or if the Company shall otherwise liquidate, dissolve or wind up,
including but not limited to the sale or transfer of all or substantially all of
the Company's assets in one transaction or in a series of related transactions
(a "Liquidation Event"), then and in that event, no distribution shall be made
to the holders of Junior Securities, unless, prior thereto, the holders of the
Designated Preferred Stock shall have first received an amount in cash or
equivalent value in securities or other consideration equal to the Liquidation
Preference thereof. If upon any liquidation, dissolution, winding up, merger,
plan of reorganization or consolidation, the amount so payable or distributable
does not equal or exceed the Liquidation Preference of the Designated Preferred
Stock, then, and in that event, the amount of cash so payable, and amount of
securities or other consideration so distributable, shall be shared ratably
among the holders of the Designated Preferred Stock.

                           VIII. ADJUSTMENTS TO PRICES

          A. SALE. The Conversion Price shall be subject to adjustment from time
to time as follows: If, for as long as any shares of Designated Preferred Stock
remain outstanding, the Company enters into a merger (other than where the
Company is the surviving entity) or consolidation with, or acquisition by,
another corporation or other entity or a sale or transfer of all or
substantially all of the assets of the Company to another person, or there is an
outstanding tender offer for the Common Stock of the Company or the Company
enters into a transaction that could result in a change in control of the
Company (collectively, a "SALE"), the Company will require, in the agreements
reflecting such transaction, that the surviving entity expressly assume the
obligations of the Company hereunder. Notwithstanding the foregoing, if the
Company enters into a Sale and the holders of the Common Stock are entitled to
receive stock, securities or property in respect of or in exchange for Common
Stock, then as a condition of such Sale, the Company and any such successor,
purchaser or transferee will agree that the Designated Preferred Stock may
thereafter be converted on the terms and subject to the conditions set forth
above into the kind and amount of stock, securities or property receivable upon
such merger, acquisition, consolidation, sale or transfer by a Holder of the
number of shares of Common Stock into which then outstanding shares of
Designated Preferred Stock might have been, pursuant to this Certificate,
converted immediately before such merger, acquisition, consolidation, sale or
transfer at the Conversion Price, subject to any adjustments which shall be as
nearly equivalent as may be practicable. In the event of any such proposed Sale,



<PAGE>

the Holder hereof shall have the right to either (i) convert all of any of the
outstanding Designated Preferred Stock by delivering a Notice of Conversion to
the Company at the Conversion Price within 15 days of receipt of notice of such
Sale from the Company or (ii) if the surviving entity in the transaction is not
a publicly traded entity listed on a Principal Trading Market, demand a
redemption of all or any of the outstanding Designated Preferred Stock at the
Redemption Price by delivering a notice to such effect to the Company within
fifteen (15) days of receipt of notice of such Sale from the Company.

               B. SPIN OFF. If, at any time prior to the Conversion Date or the
date of payment of the Company Redemption Amount hereunder, the Company
consummates a spin off or otherwise divest 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 just 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 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
shares of Designated Preferred Stock 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 DESIGNATED PREFERRED
STOCK") been converted 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 conversion of all or any of the outstanding
Designated Preferred Stock, such amount of the Reserved Spin Off Shares equal to
(x) the Reserved Spin Off Shares multiplied by (y) a fraction, of which (a) the
numerator is the principal amount of the outstanding Designated Preferred Stock
then being converted, and (b) the denominator is the principal amount of the
outstanding Designated Preferred Stock.

         C. STOCK SPLITS, ETC. If, at any time while any shares of Designated
Preferred Stock remain outstanding, the Company effectuates a stock split or
reverse stock split of its Common Stock or issues a dividend on its Common Stock
consisting of shares of Common Stock, the Conversion Price shall be equitably
adjusted to reflect such action. By way of illustration, and not in limitation,
of the foregoing (i) if the Company effectuates a 2:1 split of its Common Stock,
the Conversion Price shall be deemed to be one-half of what it had been
calculated to be immediately prior to such split; (ii) if the Company
effectuates a 1:10 reverse split of its Common Stock, thereafter, with respect
to any conversion for which the Company issues the shares after the record date
of such reverse split, the Conversion Price shall be deemed to be ten times what
it had been calculated to be immediately prior to such split; and (iii) if the
Company declares a stock dividend of one share of Common Stock for every 10
shares outstanding, thereafter the Conversion Price shall be deemed to be the
amount it had been calculated to be immediately prior to such dividend
multiplied by a fraction, of which (x) the numerator is the number of shares (10
in the example) for which a dividend share will be issued and (y) the
denominator is such number of shares plus the dividend share(s) issuable or
issued thereon (11 in the example).

         D. NOTICE OF ADJUSTMENTS. Upon the occurrence of each adjustment or
readjustment of the Conversion Price pursuant to this Article VIII, the Company,
at its expense, shall promptly compute such adjustment or readjustment and
prepare and furnish to each Holder of Designated Preferred Stock a certificate
setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based. The Company shall, upon the



<PAGE>

written request at any time of any Holder of Designated Preferred Stock, furnish
to such Holder a like certificate setting forth (i) such adjustment or
readjustment, (ii) the Conversion Price at the time in effect and (iii) the
number of shares of Common Stock and the amount, if any, of other securities or
property which at the time would be received upon conversion of a share of
Designated Preferred Stock.

                                IX. VOTING RIGHTS

         A. GENERALLY. The holders of the Designated Preferred Stock shall not
be entitled to vote with the holders of Common Stock, except as otherwise
provided by the Florida Corporation Law or otherwise contemplated by this
Certificate of Designations. To the extent that either Florida Corporation Law
or the Company's Articles of Incorporation allows or requires the vote of the
holders of the Designated Preferred Stock, voting separately as a class or
series, as applicable, to authorize a given action of the Company, the
affirmative vote or consent of the holders of 67% of the outstanding shares of
Designated Preferred Stock shall constitute the approval of such action by the
class.

                           X. CONVERSTION RESTRICTIONS

         A. CERTAIN CONVERSION RESTRICTIONS. Notwithstanding anything to the
contrary contained herein other than a conversion pursuant to Paragraphs A or B
of Article VIII, the number of shares of Common Stock that may be acquired by a
Holder upon any conversion of Designated Preferred Stock (or otherwise in
respect hereof) shall be limited to the extent necessary to insure that,
following such conversion (or other issuance), the total number of shares of
Common Stock then beneficially owned by such Holder and its Affiliates and any
other Persons whose beneficial ownership of Common Stock would be aggregated
with such Holder's for purposes of Section 13(d) of the Exchange Act, does not
exceed 9.999% of the total number of issued and outstanding shares of Common
Stock. For such purposes, beneficial ownership shall be determined in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder. Each delivery of a Conversion Notice hereunder will constitute a
representation by the applicable Holder that it has evaluated the limitation set
forth in this section and determined that issuance of the full number of
Underlying Shares requested in such Conversion Notice is permitted. This
provision shall not restrict the number of shares of Common Stock which a Holder
may receive or beneficially own in order to determine the amount of securities
or other consideration that such Holder may receive in the event of a merger or
other business combination or reclassification involving the Company as
contemplated in Article VIII herein.

                                XI. MISCELLANEOUS

         A. RANK. The Designated Preferred Stock shall rank (i) prior to the
Company's Common Stock; (ii) prior to any Junior Securities; (iii) junior to any
Senior Securities; and (iv) PARI PASSU with any Pari Passu Securities; PROVIDED,
HOWEVER, that no additional Senior Securities or Pari Passu Securities shall be
created without the written consent of two thirds of the holders of the
outstanding Designated Preferred Stock.

         B. CANCELLATION OF DESIGNATED PREFERRED STOCK. If any shares of
Designated Preferred Stock are converted or redeemed pursuant to this
Certificate of Designations, the shares so converted shall be canceled, shall
return to the status of authorized, but unissued preferred stock of no
designated series, and shall not be issuable by the Company as Designated
Preferred Stock.



<PAGE>

         C. LOST OR STOLEN CERTIFICATES. Upon receipt by the Company of (i)
evidence of the loss, theft, destruction or mutilation of any Designated
Preferred Stock certificate(s) and (ii) (y) in the case of loss, theft or
destruction, of indemnity (without any bond or other security) reasonably
satisfactory to the Company, or (z) in the case of mutilation, upon surrender
and cancellation of the Designated Preferred Stock certificate(s), the Company
shall execute and deliver new Designated Preferred Stock certificate(s) of like
tenor and date. However, the Company shall not be obligated to reissue such lost
or stolen Designated Preferred Stock certificate(s) if the Holder
contemporaneously requests the Company to convert such Designated Preferred
Stock.

         D. ALLOCATION OF RESERVED AMOUNT. The Reserved Amount shall be
allocated pro rata among the holders of Designated Preferred Stock based on the
number of shares of Designated Preferred Stock issued to each Holder. Each
increase to the Reserved Amount shall be allocated pro rata among the holders of
Designated Preferred Stock based on the number of shares of Designated Preferred
Stock held by each Holder at the time of the increase in the Reserved Amount. In
the event a Holder shall sell or otherwise transfer any of such holder's shares
of Designated Preferred Stock, each transferee shall be allocated a pro rata
portion of such transferor's Reserved Amount. Any portion of the Reserved Amount
which remains allocated to any person or entity which does not hold any
Designated Preferred Stock shall be allocated to the remaining holders of shares
of Designated Preferred Stock, pro rata based on the number of shares of
Designated Preferred Stock then held by such holders.

         E. PAYMENT OF CASH; DEFAULTS. Whenever the Company is required to make
any cash payment to a Holder under this Certificate of Designations (upon
redemption or otherwise), such cash payment shall be made to the Holder in good
funds on the date specified herein or, if not so specified, within five (5)
business days after delivery by such Holder of a notice specifying that the
Holder elects to receive such payment in cash and the method (E.G., by check,
wire transfer) in which such payment should be made. If such payment is not
delivered within the relevant time period, such Holder shall thereafter be
entitled to interest on the unpaid amount at a per annum rate equal to the lower
of 15% and the highest interest rate permitted by applicable law until such
amount is paid in full to the Holder.

         F. STATUS AS STOCKHOLDER. Upon submission of a Notice of Conversion by
a Holder of Designated Preferred Stock, (i) the shares covered thereby (other
than the shares, if any, which cannot be issued because their listing or
issuance would exceed any applicable legal or regulatory limitation) shall be
deemed converted into shares of Common Stock and (ii) the holder's rights as a
Holder of such converted shares of Designated Preferred Stock shall cease and
terminate, excepting only the right to receive certificates for such shares of
Common Stock and to any remedies provided herein or otherwise available at law
or in equity to such Holder because of a failure by the Company to comply with
the terms of this Certificate of Designations.

         G. JURY TRIAL WAIVER. The Company and, by its acceptance of the shares
of the Designated Preferred Stock, the Holder hereby waive a trial by jury in
any action, proceeding or counterclaim brought by either of the Parties hereto
against the other in respect of any matter arising out or in connection with
this Certificate of Designations.



<PAGE>

         H. AMENDMENTS. This Certificate of Designations may only be amended
with the written consent of the holders of sixty-seven (67%) percent of the
outstanding Designated Preferred Stock and the vote or action of any other party
or class entitled to vote or act thereon.

                                    EXHIBIT B

                    FORM OF NEW REGISTRATION RIGHTS AGREEMENT

                          REGISTRATION RIGHTS AGREEMENT

         This REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT") is made and
entered into effective as of _____, 2003, by and between Markland Technologies,
Inc., a Florida corporation (the "COMPANY") and Eurotech, Ltd., a District of
Columbia corporation ("EUROTECH").

                                    RECITALS

         WHEREAS, as of the date hereof, Eurotech and Markland are entering into
an Exchange Agreement (the "EXCHANGE AGREEMENT"), pursuant to which Markland has
agreed to grant to Eurotech the registration rights set forth herein.

         NOW, THEREFORE, to implement the foregoing and in consideration of the
mutual terms, conditions and covenants contained herein, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to be legally bound, agree as
follows:

1. PIGGYBACK REGISTRATION.

         RIGHT TO PIGGYBACK REGISTRATION. Subject to the terms hereof, whenever
the Company proposes to register any Company Equity Securities under the
Securities Act (other than in connection with a registration statement for
Company Equity Securities issued pursuant to the Equity Line (as defined in the
Exchange Agreement) or pursuant to a registration statement on Form S-4, Form
S-8 or any successor form) and the registration statement form to be used may be
used for the registration of Registrable Securities, the Company shall give
prompt written notice to Eurotech of its intention to effect such a
registration. Subject to Section 1(b) below, the Company shall include in such
registration and use commercially reasonable efforts to include in any
underwriting 10,000,000 shares of Registrable Securities held by Eurotech with
respect to which the Company has received a written request from Eurotech for
inclusion therein (such registration, a "PIGGYBACK REGISTRATION") within 15 days
after the receipt of the Company's notice.

         PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is an
underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold without materially and adversely affecting the marketability
of such offering or the timing thereof, the Company shall include in such
registration all Registrable Securities held by Eurotech on the condition that
Eurotech will agree to refrain from selling a reasonable number of such
Registrable Securities (as determined in good faith by the Company based on the
impact on the timing and marketability of the offering of the sale immediate by
Eurotech of all of its Registrable Securities) for a three (3) month period
following the declaration of effectiveness of the applicable registration
statement.



<PAGE>

2. REGISTRATION PROCEDURES.

         Whenever Eurotech has requested that any Registrable Securities be
registered pursuant to this Agreement, the Company shall use its reasonable best
efforts to effect the registration and the sale of such Registrable Securities
in accordance with the intended method of disposition thereof, and pursuant
thereto the Company shall as expeditiously as possible:

         (a) prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use its reasonable best efforts to cause such
registration statement to become effective;

         (b) notify Eurotech of the effectiveness of each registration statement
filed hereunder and prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
the prospectus included therein usable for a period commencing on the date that
such registration statement is initially declared effective by the SEC and
ending on the date when all Registrable Securities covered by such registration
statement have been sold pursuant to the registration statement or cease to be
Registrable Securities, and comply with the provisions of the Securities Act
with respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of
disposition by the sellers thereof set forth in such registration statement;

         (c) furnish to Eurotech such number of copies of such registration
statement, each amendment and supplement thereto, the prospectus included in
such registration statement (including each preliminary prospectus) and such
other documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by Eurotech;

         (d) use its reasonable best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as Eurotech reasonably requests and do any and all other acts and
things which may be reasonably necessary or advisable to enable Eurotech to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by Eurotech; provided, that the Company shall not be required to: (i)
qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subparagraph; (ii) subject itself
to taxation in any such jurisdiction; or (iii) consent to general service of
process in any such jurisdiction;

         (e) notify Eurotech, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration statement
contains an untrue statement of a material fact or omits any fact necessary to
make the statements therein not misleading, and, at the request of Eurotech, the
Company shall prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus shall not contain an untrue statement of a material fact or omit to
state any fact necessary to make the statements therein not misleading;

         (f) cause all such Registrable Securities to be listed or quoted on
each securities exchange or market on which similar securities issued by the
Company are then listed;



<PAGE>

         (g) provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

         (h) enter into such customary agreements (including underwriting
agreements in customary form) in order to expedite or facilitate the disposition
of such Registrable Securities;

         (i) make available for inspection by any underwriter participating in
any disposition pursuant to such registration statement, and any attorney,
accountant or other agent retained by any such underwriter, all financial and
other records, pertinent corporate documents and properties of the Company, and
cause the Company's officers, directors, managers, employees and independent
accountants to supply all information reasonably requested by any such
underwriter, attorney, accountant or agent in connection with such registration
statement;

         (j) otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least 12 months beginning with the first day of the Company's first
full calendar quarter after the effective date of the registration statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder;

         (k) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Securities included in such registration statement for sale in
any jurisdiction, the Company shall use its reasonable best efforts promptly to
obtain the withdrawal of such order;

         (l) subject to Section 2(d) above, use its reasonable best efforts to
cause any Registrable Securities covered by such registration statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to enable the sellers thereof to consummate the disposition
of such Registrable Securities; and

         (m) if the offering is underwritten, use its reasonable best efforts to
furnish on the date that Registrable Securities are delivered to the
underwriters for sale pursuant to such registration, an opinion dated such date
of counsel representing the Company for the purposes of such registration,
addressed to the underwriters covering such issues as are reasonably required by
such underwriters.

3. REGISTRATION EXPENSES.

         (a) PAYMENT OF REGISTRATION EXPENSES. All expenses incident to the
Company's performance of or compliance with this Agreement, including without
limitation all registration and filing fees, fees and expenses of compliance
with securities or blue sky laws, printing expenses, messenger and delivery
expenses, fees and disbursements of custodians, and fees and disbursements of
counsel for the Company and all independent certified public accountants,
underwriters (excluding underwriting discounts and commissions relating to the
Registrable Securities) and other Persons retained by the Company (all such
expenses being herein called "REGISTRATION EXPENSES"), shall be borne by the



<PAGE>

Company. The Company shall, in addition, pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit or
quarterly review, the expense of any liability insurance and the expenses and
fees for listing or quoting the securities to be registered on each securities
exchange on which similar securities issued by the Company are then listed or on
the NASDAQ Stock Market.

         (b) PAYMENT OF REGISTRATION EXPENSES BY HOLDERS OF REGISTRABLE
SECURITIES. To the extent Registration Expenses are not required to be paid by
the Company (including, without limitation, any underwriting discounts or
commissions that are the responsibility of the holders of Registrable
Securities), each holder of Eurotech shall pay those Registration Expenses
allocable to the registration of Eurotech's securities so included, and any
Registration Expenses not so allocable shall be payable by all sellers of
securities included in such registration in proportion to the aggregate selling
price of the securities to be so registered.

4. INDEMNIFICATION.

         (a) INDEMNIFICATION BY THE COMPANY. The Company agrees to indemnify, to
the extent permitted by law, Eurotech, its officers, directors, employees,
agents and representatives and each Person who controls Eurotech (within the
meaning of the Securities Act) against all losses, claims, damages, liabilities
and expenses caused by any untrue or alleged untrue statement of material fact
contained in any registration statement, prospectus or preliminary prospectus or
any amendment thereof or supplement thereto or any omission or alleged omission
of a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as the same are caused by or
contained in any information furnished in writing to the Company by such holder
expressly for use therein, results from the failure of Eurotech to provide
information necessary for the registration statement to the Company, or by
Eurotech's failure to deliver a copy of the registration statement or prospectus
or any amendments or supplements thereto after the Company has furnished such
holder with a sufficient number of copies of the same.

         (b) INDEMNIFICATION BY EUROTECH. In connection with any registration
statement in which Eurotech is participating, Eurotech shall furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, shall indemnify the Company, its
officers, directors, employees, agents and representatives and each Person who
controls the Company (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses resulting from any untrue or
alleged untrue statement of material fact contained in the registration
statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto resulting from such information provided by Eurotech or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading and not provided by
Eurotech; provided that the obligation to indemnify shall be be limited to the
net amount of proceeds received by Eurotech from the sale of Registrable
Securities pursuant to such registration statement.

         (c) PROCEDURE FOR INDEMNIFICATION. Any Person entitled to
indemnification hereunder shall (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification
(provided that the failure to give prompt notice shall not impair any Person's
right to indemnification hereunder to the extent such failure has not prejudiced
the indemnifying party) and (ii) unless in such indemnified party's reasonable



<PAGE>

judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party shall not
be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent shall not be unreasonably withheld). An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim shall not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim. Notwithstanding anything in
this Section 4(c) to the contrary, in the event the Company determines, in good
faith, that a claim materially affects the interests of the Company, the Company
may solely control the defense of such claim with counsel reasonably
satisfactory to the Company. In the event the Company is an indemnified party
pursuant to this Section 4, the indemnifying party may be subject to liability
if the Company settles a claim in good faith and in a reasonable manner.

5. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. Eurotech may not participate in
any registration hereunder unless Eurotech:

         (a) in the case of a registration which is underwritten, agrees to sell
Eurotech's securities on the basis provided in any underwriting arrangements
approved by the Company;

         (b) as expeditiously as possible, notifies the Company, at any time
when a prospectus relating to such Eurotech's Registrable Securities is required
to be delivered under the Securities Act, of the happening of any event as a
result of which such prospectus contains an untrue statement of a material fact
or omits any fact necessary to make the statements therein not misleading; and

         (c) completes, executes and delivers all questionnaires, powers of
attorney, indemnities, underwriting agreements and other usual and customary
documents necessary or appropriate with respect to the offering of such
