         Agreement made as of _________ __, 2004 between Chardan China
Acquisition Corp., a Delaware corporation, with offices at 777 South Highway
101, Suite 215, Solana Beach, California 92075 ("Company"), and American Stock
Transfer & Trust Company, a New York corporation, with offices at 59 Maiden
Lane, New York, New York 10038 ("Warrant Agent").

         WHEREAS, the Company is engaged in a public offering ("Public
Offering") of Units ("Units") and, in connection therewith, has determined to
issue and deliver up to (i) 8,050,000 Warrants ("Public Warrants") to the public
investors, and (ii) 700,000 Warrants to EarlyBirdCapital, Inc. ("EBC") or its
designees ("Representative's Warrants" and, together with the Public Warrants,
the "Warrants"), each of such Public Warrants evidencing the right of the holder
thereof to purchase one share of common stock, par value $.0001 per share, of
the Company's Common Stock ("Common Stock") for $5.00, subject to adjustment as
described herein; and

         WHEREAS, the Company has filed with the Securities and Exchange
Commission a Registration Statement, No. 333-111970 on Form S-1 ("Registration
Statement") for the registration, under the Securities Act of 1933, as amended
("Act") of, among other securities, the Warrants and the Common Stock issuable
upon exercise of the Warrants; and

         WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing to so act, in connection with the
issuance, registration, transfer, exchange, redemption and exercise of the
Warrants; and

         WHEREAS, the Company desires to provide for the form and provisions of
the Warrants, the terms upon which they shall be issued and exercised, and the
respective rights, limitation of rights, and immunities of the Company, the
Warrant Agent, and the holders of the Warrants; and

         WHEREAS, all acts and things have been done and performed which are
necessary to make the Warrants, when executed on behalf of the Company and
countersigned by or on behalf of the Warrant Agent, as provided herein, the
valid, binding and legal obligations of the Company, and to authorize the
execution and delivery of this Agreement.

         NOW, THEREFORE, in consideration of the mutual agreements herein
contained, the parties hereto agree as follows:

<PAGE>

1.       Appointment of Warrant Agent. The Company hereby appoints the Warrant
Agent to act as agent for the Company for the Warrants, and the Warrant Agent
hereby accepts such appointment and agrees to perform the same in accordance
with the terms and conditions set forth in this Agreement.

2.       Warrants.

         2.1.     Form of Warrant. Each Warrant shall be issued in registered
form only, shall be in substantially the form of Exhibit A hereto, the
provisions of which are incorporated herein and shall be signed by, or bear the
facsimile signature of, the Chairman of the Board or President and Treasurer,
Secretary or Assistant Secretary of the Company and shall bear a facsimile of
the Company's seal. In the event the person whose facsimile signature has been
placed upon any Warrant shall have ceased to serve in the capacity in which such
person signed the Warrant before such Warrant is issued, it may be issued with
the same effect as if he or she had not ceased to be such at the date of
issuance.

         2.2.     Effect of Countersignature. Unless and until countersigned by
the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of
no effect and may not be exercised by the holder thereof.

         2.3.     Registration.

                  2.3.1. Warrant Register. The Warrant Agent shall maintain
books ("Warrant Register"), for the registration of original issuance and the
registration of transfer of the Warrants. Upon the initial issuance of the
Warrants, the Warrant Agent shall issue and register the Warrants in the names
of the respective holders thereof in such denominations and otherwise in
accordance with instructions delivered to the Warrant Agent by the Company.

                  2.3.2. Registered Holder. Prior to due presentment for
registration of transfer of any Warrant, the Company and the Warrant Agent may
deem and treat the person in whose name such Warrant shall be registered upon
the Warrant Register ("registered holder"), as the absolute owner of such
Warrant and of each Warrant represented thereby (notwithstanding any notation of
ownership or other writing on the Warrant Certificate made by anyone other than
the Company or the Warrant Agent), for the purpose of any exercise thereof, and
for all other purposes, and neither the Company nor the Warrant Agent shall be
affected by any notice to the contrary.


                                       2
<PAGE>

         2.4.     Detachability of Warrants. The securities comprising the Units
will not be separately transferable until 90 days after the date hereof unless
EBC informs the Company of its decision to allow earlier separate trading, but
in no event will EBC allow separate trading of the securities comprising the
Units until the Company files a Current Report on Form 8-K which includes an
audited balance sheet reflecting the receipt by the Company of the gross
proceeds of the Public Offering including the proceeds received by the Company
from the exercise of the Underwriter's over-allotment option, if the
over-allotment option is exercised prior to the filing of the Form 8-K.

         2.5      Warrants and Representative's Warrants. The Representative's
Warrants shall have the same terms and be in the same form as the Public
Warrants except with respect to the Warrant Price as set forth below in
Section 3.1.

3.       Terms and Exercise of Warrants

         3.1.     Warrant Price. Each Public Warrant shall, when countersigned
by the Warrant Agent, entitle the registered holder thereof, subject to the
provisions of such Public Warrant and of this Warrant Agreement, to purchase
from the Company the number of shares of Common Stock stated therein, at the
price of $5.00 per whole share, subject to the adjustments provided in Section 4
hereof and in the last sentence of this Section 3.1. Each Representative's
Warrant shall, when countersigned by the Warrant Agent, entitle the registered
holder thereof, subject to the provisions of such Representative's Warrant and
of this Warrant Agreement, to purchase from the Company the number of shares of
Common Stock stated therein, at the price of $6.40 per whole share, subject to
the adjustments provided in Section 4 hereof. The term "Warrant Price" as used
in this Warrant Agreement refers to the price per share at which Common Stock
may be purchased at the time a Warrant is exercised. The Company in its sole
discretion may lower the Warrant Price at any time prior to the Expiration Date.

         3.2.     Duration of Warrants. A Warrant may be exercised only during
the period ("Exercise Period") commencing on the later of the consummation by
the Company of a merger, capital stock exchange, asset acquisition or other
similar business combination ("Business Combination") (as described more fully
in the Company's Registration Statement) or _________ ___, 2005, and terminating
at 5:00 p.m., New York City time on the earlier to occur of (i) ________ ___,
2008 or (ii) the date fixed for redemption of the Warrants as provided in
Section 6 of this Agreement ("Expiration Date"). Except with respect to the
right to receive the Redemption Price (as set forth in Section 6 hereunder),
each Warrant not exercised on or before the Expiration Date shall become void,
and all rights thereunder and all rights in respect thereof under this Agreement
shall cease at the close of business on the Expiration Date. The Company in its
sole discretion may extend the duration of the Warrants by delaying the
Expiration Date.

         3.3.     Exercise of Warrants.


                                       3
<PAGE>

                  3.3.1. Payment. Subject to the provisions of the Warrant and
this Warrant Agreement, a Warrant, when countersigned by the Warrant Agent, may
be exercised by the registered holder thereof by surrendering it, at the office
of the Warrant Agent, or at the office of its successor as Warrant Agent, in the
Borough of Manhattan, City and State of New York, with the subscription form, as
set forth in the Warrant, duly executed, and by paying in full, in lawful money
of the United States, in cash, good certified check or good bank draft payable
to the order of the Company (or as otherwise agreed to by the Company), the
Warrant Price for each full share of Common Stock as to which the Warrant is
exercised and any and all applicable taxes due in connection with the exercise
of the Warrant, the exchange of the Warrant for the Common Stock, and the
issuance of the Common Stock.

                  3.3.2. Issuance of Certificates. As soon as practicable after
the exercise of any Warrant and the clearance of the funds in payment of the
Warrant Price, the Company shall issue to the registered holder of such Warrant
a certificate or certificates for the number of full shares of Common Stock to
which he is entitled, registered in such name or names as may be directed by
him, her or it, and if such Warrant shall not have been exercised in full, a new
countersigned Warrant for the number of shares as to which such Warrant shall
not have been exercised. Notwithstanding the foregoing, the Company shall not be
obligated to deliver any securities pursuant to the exercise of a Warrant unless
a registration statement under the Act with respect to the Common Stock is
effective. Warrants may not be exercised by, or securities issued to, any
registered holder in any state in which such exercise would be unlawful.

                  3.3.3. Valid Issuance. All shares of Common Stock issued upon
the proper exercise of a Warrant in conformity with this Agreement shall be
validly issued, fully paid and nonassessable.

                  3.3.4. Date of Issuance. Each person in whose name any such
certificate for shares of Common Stock is issued shall for all purposes be
deemed to have become the holder of record of such shares on the date on which
the Warrant was surrendered and payment of the Warrant Price was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open.

                  3.3.5. Warrant Solicitation and Warrant Solicitation Fee.

                         a. The Company has engaged EBC, on a non-exclusive
basis, as its agent for the solicitation of the exercise of the Warrants. The
Company, at its cost, will (i) assist EBC with respect to such solicitation, if
requested by EBC, and (ii) provide EBC, and direct the Company's transfer agent
and the Warrant Agent to deliver to EBC, lists of the record and, to the extent
known, beneficial owners of the Company's Warrants. The Company hereby instructs
the Warrant Agent to cooperate with EBC in every respect in connection with
EBC's solicitation activities, including, but not limited to, providing to EBC,
at the Company's cost, a list of record and beneficial holders of the Warrants
and circulating a prospectus or offering circular disclosing the compensation
arrangements referenced in Section 3.3.5(b) below to holders of the Warrants at
the time of exercise of the Warrants. In addition to the conditions set forth in
Section 3.3.5(b), EBC shall accept payment of the warrant solicitation fee
provided in Section 3.3.5(b) only if it has provided bona fide services to the
Company in connection with the exercise of the Warrants and only to the extent
that an investor who exercises his Warrants specifically designates, in writing,
that EBC solicited his exercise. In addition to soliciting, either orally or in
writing, the exercise of Warrants by a Warrant holder, such services may also
include disseminating information, either orally or in writing, to Warrant
holders about the Company or the market for the Company's securities, or
assisting in the processing of the exercise of Warrants.

                         b. In each instance in which a Warrant is exercised,
the Warrant Agent shall promptly give written notice of such exercise to the
Company and EBC ("Warrant Agent's Exercise Notice"). If, upon the exercise of
any Warrant more than one year from the effective date of the Registration
Statement, (i) the market price of the Company's Common Stock is greater than
the Warrant Price, (ii) disclosure of compensation arrangements between the
Company and EBC with respect to the solicitation of the exercise of the Warrants
was made both at the time of the Public Offering and at the time of exercise (by
delivery of the Prospectus or as otherwise required by applicable law, rule or
regulation), (iii) the holder of the Warrant confirms in writing that the
exercise of the Warrant was solicited by EBC, (iv) the Warrant was not held in a
discretionary account, and (v) the solicitation of the exercise of the Warrant
was not in violation of Regulation M (as such rule or any successor rule may be
in effect as of such time of exercise) promulgated under the Securities Exchange
Act of 1934, as amended, then the Warrant Agent, simultaneously with the
distribution of the Common Stock underlying the Warrants so exercised in
accordance with the instructions from the Company following receipt of the
proceeds to the Company received upon exercise of such Warrant(s), shall, on
behalf of the Company, pay a fee of 5% of the Warrant Price to EBC, provided
that EBC delivers to the Warrant Agent within ten (10) business days from the
date on which EBC has received the Warrant Agent's Exercise Notice, a
certificate that the conditions set forth


                                       5
<PAGE>

in the preceding clauses (iii), (iv) and (v) have been satisfied.
Notwithstanding the foregoing, no fee will be paid to EBC with respect to the
exercise by the Underwriters or their affiliates or the Company's officers or
directors of Warrants purchased by it or them upon exercise of the
Representative's Warrants and still held by any of the Underwriters or them for
its or their own account. EBC and the Company may at any time during business
hours, examine the records of the Warrant Agent, including its ledger of
original Warrant certificates returned to the Warrant Agent upon exercise of
Warrants.

                         c. The provisions of this Section 3.3.5. may not be
modified, amended or deleted without the prior written consent of EBC.

4.       Adjustments.

         4.1. Stock Dividends - Split-Ups. If after the date hereof, and subject
to the provisions of Section 4.6 below, the number of outstanding shares of
Common Stock is increased by a stock dividend payable in shares of Common Stock,
or by a split-up of shares of Common Stock, or other similar event, then, on the
effective date of such stock dividend, split-up or similar event, the number of
shares of Common Stock issuable on exercise of each Warrant shall be increased
in proportion to such increase in outstanding shares of Common Stock.

         4.2. Aggregation of Shares. If after the date hereof, and subject to
the provisions of Section 4.6, the number of outstanding shares of Common Stock
is decreased by a consolidation, combination, reverse stock split or
reclassification of shares of Common Stock or other similar event, then, on the
effective date of such consolidation, combination, reverse stock split,
reclassification or similar event, the number of shares of Common Stock issuable
on exercise of each Warrant shall be decreased in proportion to such decrease in
outstanding shares of Common Stock.

         4.3 Adjustments in Exercise Price. Whenever the number of shares of
Common Stock purchasable upon the exercise of the Warrants is adjusted, as
provided in Section 4.1 and 4.2 above, the Warrant Price shall be adjusted (to
the nearest cent) by multiplying such Warrant Price immediately prior to such
adjustment by a fraction (x) the numerator of which shall be the number of
shares of Common Stock purchasable upon the exercise of the Warrants immediately
prior to such adjustment, and (y) the denominator of which shall be the number
of shares of Common Stock so purchasable immediately thereafter.

         4.4. Replacement of Securities upon Reorganization, etc. In case of any
reclassification or


                                       6
<PAGE>

reorganization of the outstanding shares of Common Stock (other than a change
covered by Section 4.1 or 4.2 hereof or that solely affects the par value of
such shares of Common Stock), or in the case of any merger or consolidation of
the Company with or into another corporation (other than a consolidation or
merger in which the Company is the continuing corporation and that does not
result in any reclassification or reorganization of the outstanding shares of
Common Stock), or in the case of any sale or conveyance to another corporation
or entity of the assets or other property of the Company as an entirety or
substantially as an entirety in connection with which the Company is dissolved,
the Warrant holders shall thereafter have the right to purchase and receive,
upon the basis and upon the terms and conditions specified in the Warrants and
in lieu of the shares of Common Stock of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented thereby,
the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such reclassification, reorganization, merger
or consolidation, or upon a dissolution following any such sale or transfer,
that the Warrant holder would have received if such Warrant holder had exercised
his, her or its Warrant(s) immediately prior to such event; and if any
reclassification also results in a change in shares of Common Stock covered by
Section 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1,
4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall
similarly apply to successive reclassifications, reorganizations, mergers or
consolidations, sales or other transfers.

         4.5. Notices of Changes in Warrant. Upon every adjustment of the
Warrant Price or the number of shares issuable upon exercise of a Warrant, the
Company shall give written notice thereof to the Warrant Agent, which notice
shall state the Warrant Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares purchasable at such price upon the
exercise of a Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based. Upon the
occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any
such event, the Company shall give written notice to the Warrant holder, at the
last address set forth for such holder in the warrant register, of the record
date or the effective date of the event. Failure to give such notice, or any
defect therein, shall not affect the legality or validity of such event.

         4.6. No Fractional Shares. Notwithstanding any provision contained in
this Warrant Agreement to the contrary, the Company shall not issue fractional
shares upon exercise of Warrants. If, by reason of any adjustment made pursuant
to this Section 4, the holder of any Warrant would be entitled, upon the
exercise of such Warrant, to receive a fractional interest in a share, the
Company shall, upon such exercise, round up to the nearest whole number the
number of the shares of Common Stock to be issued to the Warrant holder.


                                       7
<PAGE>

         4.7. Form of Warrant. The form of Warrant need not be changed because
of any adjustment pursuant to this Section 4, and Warrants issued after such
adjustment may state the same Warrant Price and the same number of shares as is
stated in the Warrants initially issued pursuant to this Agreement. However, the
Company may at any time in its sole discretion make any change in the form of
Warrant that the Company may deem appropriate and that does not affect the
substance thereof, and any Warrant thereafter issued or countersigned, whether
in exchange or substitution for an outstanding Warrant or otherwise, may be in
the form as so changed.

5.       Transfer and Exchange of Warrants.

         5.1. Registration of Transfer. The Warrant Agent shall register the
transfer, from time to time, of any outstanding Warrant upon the Warrant
Register, upon surrender of such Warrant for transfer, properly endorsed with
signatures properly guaranteed and accompanied by appropriate instructions for
transfer. Upon any such transfer, a new Warrant representing an equal aggregate
number of Warrants shall be issued and the old Warrant shall be cancelled by the
Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent
to the Company from time to time upon request.

         5.2. Procedure for Surrender of Warrants. Warrants may be surrendered
to the Warrant Agent, together with a written request for exchange or transfer,
and thereupon the Warrant Agent shall issue in exchange therefor one or more new
Warrants as requested by the registered holder of the Warrants so surrendered,
representing an equal aggregate number of Warrants; provided, however, that in
the event that a Warrant surrendered for transfer bears a restrictive legend,
the Warrant Agent shall not cancel such Warrant and issue new Warrants in
exchange therefor until the Warrant Agent has received an opinion of counsel for
the Company stating that such transfer may be made and indicating whether the
new Warrants must also bear a restrictive legend.

         5.3. Fractional Warrants. The Warrant Agent shall not be required to
effect any registration of transfer or exchange which will result in the
issuance of a warrant certificate for a fraction of a warrant.

         5.4. Service Charges. No service charge shall be made for any exchange
or registration of transfer of Warrants.

         5.5. Warrant Execution and Countersignature. The Warrant Agent is
hereby authorized to countersign and to deliver, in accordance with the terms of
this Agreement, the Warrants required to be issued pursuant to the provisions of
this Section 5, and the Company, whenever required by the Warrant


                                       8
<PAGE>

Agent, will supply the Warrant Agent with Warrants duly executed on behalf of
the Company for such purpose.

6.       Redemption.

         6.1. Redemption. Subject to Section 6.4 hereof, with the prior consent
of EBC, not less than all of the outstanding Warrants may be redeemed, at the
option of the Company, at any time after they become exercisable and prior to
their expiration, at the office of the Warrant Agent, upon the notice referred
to in Section 6.2., at the price of $.01 per Warrant ("Redemption Price"),
provided that the last sales price of the Common Stock has been at least $8.50
per share, on each of twenty (20) trading days within any thirty (30) trading
day period ending on the third business day prior to the date on which notice of
redemption is given. The provisions of this Section 6.1 may not be modified,
amended or deleted without the prior written consent of EBC.

         6.2. Date Fixed for, and Notice of, Redemption. In the event the
Company shall elect to redeem all of the Warrants, the Company shall fix a date
for the redemption. Notice of redemption shall be mailed by first class mail,
postage prepaid, by the Company not less than 30 days prior to the date fixed
for redemption to the registered holders of the Warrants to be redeemed at their
last addresses as they shall appear on the registration books. Any notice mailed
in the manner herein provided shall be conclusively presumed to have been duly
given whether or not the registered holder received such notice.

         6.3. Exercise After Notice of Redemption. The Warrants may be exercised
in accordance with Section 3 of this Agreement at any time after notice of
redemption shall have been given by the Company pursuant to Section 6.2. hereof
and prior to the time and date fixed for redemption. On and after the redemption
date, the record holder of the Warrants shall have no further rights except to
receive, upon surrender of the Warrants, the Redemption Price.

         6.4 Outstanding Warrants Only. The Company understands that the
redemption rights provided for by this Section 6 apply only to outstanding
Warrants. To the extent a person holds rights to purchase Warrants, such
purchase rights shall not be extinguished by redemption. However, once such
purchase rights are exercised, the Company may redeem the Warrants issued upon
such exercise provided that the criteria for redemption is met. The provisions
of this Section 6.4 may not be modified, amended or deleted without the prior
written consent of EBC.


                                       9
<PAGE>

7.       Other Provisions Relating to Rights of Holders of Warrants.

         7.1. No Rights as Stockholder. A Warrant does not entitle the
registered holder thereof to any of the rights of a stockholder of the Company,
including, without limitation, the right to receive dividends, or other
distributions, exercise any preemptive rights to vote or to consent or to
receive notice as stockholders in respect of the meetings of stockholders or the
election of directors of the Company or any other matter.

         7.2. Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is
lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on
such terms as to indemnity or otherwise as they may in their discretion impose
(which shall, in the case of a mutilated Warrant, include the surrender
thereof), issue a new Warrant of like denomination, tenor, and date as the
Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall
constitute a substitute contractual obligation of the Company, whether or not
the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time
enforceable by anyone.

         7.3. Reservation of Common Stock. The Company shall at all times
reserve and keep available a number of its authorized but unissued shares of
Common Stock that will be sufficient to permit the exercise in full of all
outstanding Warrants issued pursuant to this Agreement.

         7.4. Registration of Common Stock. The Company agrees that prior to the
commencement of the Exercise Period, it shall file with the Securities and
Exchange Commission a post-effective amendment to the Registration Statement, or
a new registration statement, for the registration, under the Act, of, and it
shall take such action as is necessary to qualify for sale, in those states in
which the Warrants were initially offered by the Company, the Common Stock
issuable upon exercise of the Warrants. In either case, the Company will use its
best efforts to cause the same to become effective and to maintain the
effectiveness of such registration statement until the expiration of the
Warrants in accordance with the provisions of this Agreement. The provisions of
this Section 7.4 may not be modified, amended or deleted without the prior
written consent of EBC.

8.       Concerning the Warrant Agent and Other Matters.

         8.1.     Payment of Taxes. The Company will from time to time promptly
pay all taxes and charges that may be imposed upon the Company or the Warrant
Agent in respect of the issuance or delivery of shares of Common Stock upon the
exercise of Warrants, but the Company shall not be obligated to pay any transfer
taxes in respect of the Warrants or such shares.

         8.2.     Resignation, Consolidation, or Merger of Warrant Agent.

                  8.2.1. Appointment of Successor Warrant Agent. The Warrant
Agent, or any successor to it hereafter appointed, may resign its duties and be
discharged from all further duties and liabilities hereunder after giving sixty
(60) days' notice in writing to the Company. If the office of the Warrant Agent
becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant
Agent. If the Company shall fail to make such appointment within a period of 30
days after it has been notified in writing of such resignation or incapacity by
the Warrant Agent or by the holder of the Warrant (who shall, with such notice,
submit his Warrant for inspection by the Company), then the holder of any
Warrant may apply to the Supreme Court of the State of New York for the County
of New York for the appointment of a successor Warrant Agent at the Company's
cost. Any successor Warrant Agent, whether appointed by the Company or by such
court, shall be a corporation organized and existing under the laws of the State
of New York, in good standing and having its principal office in the Borough of
Manhattan, City and State of New York, and authorized under such laws to
exercise corporate trust powers and subject to supervision or examination by
federal or state authority. After appointment, any successor Warrant Agent shall
be vested with all the authority, powers, rights, immunities, duties, and
obligations of its predecessor Warrant Agent with like effect as if originally
named as Warrant Agent hereunder, without any further act or deed; but if for
any reason it becomes necessary or appropriate, the predecessor Warrant Agent
shall execute and deliver, at the expense of the Company, an instrument
transferring to such successor Warrant Agent all the authority, powers, and
rights of such predecessor Warrant Agent hereunder; and upon request of any
successor Warrant Agent the Company shall make, execute, acknowledge, and
deliver any and all instruments in writing for more fully and effectually
vesting in and confirming to such successor Warrant Agent all such authority,
powers, rights, immunities, duties, and obligations.

                  8.2.2. Notice of Successor Warrant Agent. In the event a
successor Warrant Agent shall be appointed, the Company shall give notice
thereof to the predecessor Warrant Agent and the transfer agent for the Common
Stock not later than the effective date of any such appointment.

<PAGE>

                  8.2.3. Merger or Consolidation of Warrant Agent. Any
corporation into which the Warrant Agent may be merged or with which it may be
consolidated or any corporation resulting from any merger or consolidation to
which the Warrant Agent shall be a party shall be the successor Warrant Agent
