                  THIS CERTIFIES THAT, in consideration of $_____ per option
duly paid by or on behalf of ____________________ ("Holder"), as registered
owner of this Purchase Option, to Chardan China Acquisition Corp. ("Company"),

Company, each Unit consisting of one share of common stock of the Company, par
value $.0001 per share ("Common Stock"), and two warrants ("Warrant(s)")
expiring four years from the effective date ("Effective Date") of the
registration statement ("Registration Statement") pursuant to which Units are
offered for sale to the public ("Offering"). Each Warrant is the same as the
warrants included in the Units being registered for sale to the public by way of
the Registration Statement ("Public Warrants") except that the Warrants have an
exercise price of $6.40 per share. If the Expiration Date is a day on which
banking institutions are authorized by law to close, then this Purchase Option

accordance with the terms herein. During the period ending on the Expiration
Date, the Company agrees not to take any action that would terminate the
Purchase Option. This Purchase Option is initially

                                       1
<PAGE>

exercisable at $9.90 per Unit so purchased; provided, however, that upon the
occurrence of any of the events specified in Section 6 hereof, the rights
granted by this Purchase Option, including the exercise price per Unit and the
number of Units (and shares of Common Stock and Warrants) to be received upon
such exercise, shall be adjusted as therein specified. The term "Exercise Price"
shall mean the initial exercise price or the adjusted exercise price, depending
on the context.

2.       Exercise.

         2.1 Exercise Form. In order to exercise this Purchase Option, the
exercise form attached hereto must be duly executed and completed and delivered
to the Company, together with this Purchase Option and payment of the Exercise
Price for the Units being purchased payable in cash or by certified check or
official bank check. If the subscription rights represented hereby shall not be
exercised at or before 5:00 p.m., Eastern time, on the Expiration Date this
Purchase Option shall become and be void without further force or effect, and
all rights represented hereby shall cease and expire.

         2.2 Legend. Each certificate for the securities purchased under this
Purchase Option shall bear a legend as follows unless such securities have been
registered under the Securities Act of 1933, as amended ("Act"):

                  "The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act") or applicable state law. The securities may not be
                  offered for sale, sold or otherwise transferred except
                  pursuant to an effective registration statement under the Act,
                  or pursuant to an exemption from registration under the Act
                  and applicable state law."

         2.3      Cashless Exercise.

                  2.3.1 Determination of Amount. In lieu of the payment of the
Exercise Price multiplied by the number of Units for which this Purchase Option
is exercisable (and in lieu of being entitled to receive Common Stock and
Warrants) in the manner required by Section 2.1, the Holder shall have the right
(but not the obligation) to convert any exercisable but unexercised portion of
this Purchase Option into Units ("Conversion Right") as follows: upon exercise
of the Conversion Right, the Company shall deliver to the Holder (without
payment by the Holder of any of the Exercise Price in cash) that number of
shares of Common Stock and Warrants comprising that number of Units equal to the
quotient obtained by dividing (x) the "Value" (as defined below) of the portion
of the Purchase Option being converted by (y) the Current Market Value (as
defined below). The "Value" of the portion of the Purchase Option being
converted shall equal the remainder derived from subtracting (a) (i) the
Exercise Price multiplied by (ii) the number of Units underlying the portion of
this Purchase Option being converted from (b) the Current Market Value of a Unit
multiplied by the number of Units underlying the portion of the Purchase Option
being converted. As used herein, the term "Current Market Value" per Unit at any
date means the remainder derived from subtracting (x) the exercise price of the
Warrants multiplied by the number of shares of Common Stock issuable upon
exercise of the Warrants underlying one Unit from (y) the Current Market Price
of the Common Stock multiplied by the number of shares of Common Stock
underlying the Warrants and the Common Stock issuable upon exercise of one Unit.
The "Current Market Price" of a share of Common Stock shall mean (i) if the
Common Stock is listed on a national securities exchange or quoted on the Nasdaq
National Market, Nasdaq SmallCap Market or NASD OTC Bulletin Board (or successor
such as the Bulletin Board Exchange), the last sale price of the Common Stock in
the principal trading market for the Common Stock as reported by the exchange,

                                       2
<PAGE>

Nasdaq or the NASD, as the case may be; (ii) if the Common Stock is not listed
on a national securities exchange or quoted on the Nasdaq National Market,
Nasdaq SmallCap Market or the NASD OTC Bulletin Board (or successor such as the
Bulletin Board Exchange), but is traded in the residual over-the-counter market,
the closing bid price for the Common Stock on the last trading day preceding the
date in question for which such quotations are reported by the Pink Sheets, LLC
or similar publisher of such quotations; and (iii) if the fair market value of
the Common Stock cannot be determined pursuant to clause (i) or (ii) above, such
price as the Board of Directors of the Company shall determine, in good faith.

                  2.3.2 Mechanics of Cashless Exercise. The Cashless Exercise
Right may be exercised by the Holder on any business day on or after the
Commencement Date and not later than the Expiration Date by delivering the
Purchase Option with the duly executed exercise form attached hereto with the
cashless exercise section completed to the Company, exercising the Cashless
Exercise Right and specifying the total number of Units the Holder will purchase
pursuant to such Cashless Exercise Right.

3.       Transfer.

         3.1 General Restrictions. The registered Holder of this Purchase
Option, by its acceptance hereof, agrees that it will not sell, transfer,
assign, pledge or hypothecate this Purchase Option for a period of two years
following the Effective Date to anyone other than (i) EBC or an underwriter or a
selected dealer in connection with the Offering, or (ii) a bona fide officer or
partner of EBC or of any such underwriter or selected dealer. On and after the
second anniversary of the Effective Date, transfers to others may be made
subject to compliance with or exemptions from applicable securities laws. In
order to make any permitted assignment, the Holder must deliver to the Company
the assignment form attached hereto duly executed and completed, together with
the Purchase Option and payment of all transfer taxes, if any, payable in
connection therewith. The Company shall within five business days transfer this
Purchase Option on the books of the Company and shall execute and deliver a new
Purchase Option or Purchase Options of like tenor to the appropriate assignee(s)
expressly evidencing the right to purchase the aggregate number of Units
purchasable hereunder or such portion of such number as shall be contemplated by
any such assignment.

         3.2 Restrictions Imposed by the Act. The securities evidenced by this
Purchase Option shall not be transferred unless and until (i) the Company has
received the opinion of counsel for the Holder that the securities may be
transferred pursuant to an exemption from registration under the Act and
applicable state securities laws, the availability of which is established to
the reasonable satisfaction of the Company (the Company hereby agreeing that the
opinion of Graubard Miller shall be deemed satisfactory evidence of the
availability of an exemption), or (ii) a registration statement or a
post-effective amendment to the Registration Statement relating to such
securities has been filed by the Company and declared effective by the
Securities and Exchange Commission and compliance with applicable state
securities law has been established.

                                       3

4.       New Purchase Options to be Issued.

         4.1 Partial Exercise or Transfer. Subject to the restrictions in
Section 3 hereof, this Purchase Option may be exercised or assigned in whole or
in part. In the event of the exercise or assignment hereof in part only, upon
surrender of this Purchase Option for cancellation, together with the duly
executed exercise or assignment form and funds sufficient to pay any Exercise
Price and/or transfer tax, the Company shall cause to be delivered to the Holder
without charge a new Purchase Option of like tenor to this Purchase Option in
the name of the Holder evidencing the right of the Holder to purchase the number
of Units purchasable hereunder as to which this Purchase Option has not been
exercised or assigned.

         4.2 Lost Certificate. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Option and of reasonably satisfactory indemnification or the posting of
a bond, the Company shall execute and deliver a new Purchase Option of like
tenor and date. Any such new Purchase Option executed and delivered as a result
of such loss, theft, mutilation or destruction shall constitute a substitute
contractual obligation on the part of the Company.

5.       Registration Rights.

         5.1      Demand Registration.

                  5.1.1 Grant of Right. The Company, upon written demand
("Initial Demand Notice") of the Holder(s) of at least 51% of the Purchase
Options and/or the underlying Units and/or the underlying securities ("Majority
Holders"), agrees to register on one occasion, all or any portion of the
Purchase Options requested by the Majority Holders in the Initial Demand Notice
and all of the securities underlying such Purchase Options, including the Units,
Common Stock, the Warrants and the Common Stock underlying the Warrants
(collectively, the "Registrable Securities"). On such occasion, the Company will
file a registration statement or a post-effective amendment to the Registration
Statement covering the Registrable Securities within sixty days after receipt of
the Initial Demand Notice and use its best efforts to have such registration
statement or post-effective amendment declared effective as soon as possible
thereafter. The demand for registration may be made at any time during a period
of five years beginning on the Effective Date. The Company covenants and agrees
to give written notice of its receipt of any Initial Demand Notice by any
Holder(s) to all other registered Holders of the Purchase Options and/or the
Registrable Securities within ten days from the date of the receipt of any such
Initial Demand Notice.

                  5.1.2 Terms. The Company shall bear all fees and expenses
attendant to registering the Registrable Securities, including the expenses of
any legal counsel selected by the Holders to represent them in connection with
the sale of the Registrable Securities, but the Holders shall pay any and all
underwriting commissions. The Company agrees to use its reasonable best efforts
to qualify or register the Registrable Securities in such States as are
reasonably requested by the Majority Holder(s); provided, however, that in no
event shall the Company be required to register the Registrable Securities in a
State in which such registration would cause (i) the Company to be obligated to
qualify to do business in such State, or would subject the Company to taxation
as a foreign corporation doing business in such jurisdiction or (ii) the
principal stockholders of the Company to be obligated to escrow their shares of
capital stock of the Company. The Company shall cause any registration statement
or post-effective amendment filed pursuant to the demand rights granted under
Section 5.1.1 to remain effective

                                       4
<PAGE>

for a period of nine consecutive months from the effective date of such
registration statement or post-effective amendment.

         5.2      "Piggy-Back" Registration.

                  5.2.1 Grant of Right. In addition to the demand right of
registration, the Holders of the Purchase Options shall have the right for a
period of seven years commencing on the Effective Date, to include the
Registrable Securities as part of any other registration of securities filed by
the Company (other than in connection with a transaction contemplated by Rule
145(a) promulgated under the Act or pursuant to Form S-8); provided, however,
that if, in the written opinion of the Company's managing underwriter or
underwriters, if any, for such offering, the inclusion of the Registrable
Securities, when added to the securities being registered by the Company or the
selling stockholder(s), will exceed the maximum amount of the Company's
securities which can be marketed (i) at a price reasonably related to their then
current market value, and (ii) without materially and adversely affecting the
entire offering, then the Company will still be required to include the
Registrable Securities, but may require the Holders to agree, in writing, to
delay the sale of all or any portion of the Registrable Securities for a period
of 90 days from the effective date of the offering, provided, further, that if
the sale of any Registrable Securities is so delayed, then the number of
securities to be sold by all stockholders in such public offering during such 90
day period shall be apportioned pro rata among all such selling stockholders,
including all holders of the Registrable Securities, according to the total
amount of securities of the Company owned by said selling stockholders,
including all holders of the Registrable Securities.

                  5.2.2 Terms. The Company shall bear all fees and expenses
attendant to registering the Registrable Securities, including the expenses of
any legal counsel selected by the Holders to represent them in connection with
the sale of the Registrable Securities but the Holders shall pay any and all
underwriting commissions related to the Registrable Securities. In the event of
such a proposed registration, the Company shall furnish the then Holders of
outstanding Registrable Securities with not less than fifteen days written
notice prior to the proposed date of filing of such registration statement. Such
notice to the Holders shall continue to be given for each applicable
registration statement filed (during the period in which the Purchase Option is
exercisable) by the Company until such time as all of the Registrable Securities
have been registered and sold. The holders of the Registrable Securities shall
exercise the "piggy-back" rights provided for herein by giving written notice,
within ten days of the receipt of the Company's notice of its intention to file
a registration statement. The Company shall cause any registration statement
filed pursuant to the above "piggyback" rights to remain effective for at least
nine months from the date that the Holders of the Registrable Securities are
first given the opportunity to sell all of such securities.

         5.3 Damages. Should the registration or the effectiveness thereof
required by Sections 5.1 and 5.2 hereof be delayed by the Company or the Company
otherwise fails to comply with such provisions, the Company shall, in addition
to any other equitable or other relief available to the Holder(s), be liable for
any and all incidental, special and consequential damages sustained by the
Holder(s), including, but not limited to, the loss of any profits that might
have been received by the holder upon the sale of shares of Common Stock or
Warrants (and shares of Common Stock underlying the Warrants) underlying this
Purchase Option.

         5.4      General Terms.

                  5.4.1 Indemnification. The Company shall indemnify the
Holder(s) of the Registrable

                                       5
<PAGE>

Securities to be sold pursuant to any registration statement hereunder and each
person, if any, who controls such Holders within the meaning of Section 15 of
the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended
("Exchange Act"), against all loss, claim, damage, expense or liability
(including all reasonable attorneys' fees and other expenses reasonably incurred
in investigating, preparing or defending against litigation, commenced or
threatened, or any claim whatsoever whether arising out of any action between
the Underwriter and the Company or between the Underwriter and any third party
or otherwise) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify the Underwriters contained in Section 5 of the
Underwriting Agreement between the Company, EBC and the other Underwriters named
therein dated the Effective Date. The Holder(s) of the Registrable Securities to
be sold pursuant to such registration statement, and their successors and
assigns, shall severally, and not jointly, indemnify the Company, its officers
and directors and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against
all loss, claim, damage, expense or liability (including all reasonable
attorneys' fees and other expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information
furnished by or on behalf of such Holders, or their successors or assigns, in
writing, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 5 of the
Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company.

                  5.4.2 Exercise of Purchase Options. Nothing contained in this
Purchase Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options or Warrants underlying such Purchase Options prior to or after
the initial filing of any registration statement or the effectiveness thereof.

                  5.4.3 Documents Delivered to Holders. The Company shall
furnish EBC, as representative of the Holders participating in any of the
foregoing offerings, a signed counterpart, addressed to the participating
Holders, of (i) an opinion of counsel to the Company, dated the effective date
of such registration statement (and, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under any
underwriting agreement related thereto), and (ii) a "cold comfort" letter dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting agreement) signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities. The Company shall
also deliver promptly to EBC, as

                                       6
<PAGE>

representative of the Holders participating in the offering, the correspondence
and memoranda described below and copies of all correspondence between the
Commission and the Company, its counsel or auditors and all memoranda relating
to discussions with the Commission or its staff with respect to the registration
statement and permit EBC, as representative of the Holders, to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the National
Association of Securities Dealers, Inc. ("NASD"). Such investigation shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times and as often as EBC, as
representative of the Holders, shall reasonably request. The Company shall not
be required to disclose any confidential information or other records to EBC, as
representative of the Holders, or to any other person, until and unless such
persons shall have entered into reasonable confidentiality agreements (in form
and substance reasonably satisfactory to the Company), with the Company with
respect thereto.

                  5.4.4 Underwriting Agreement. The Company shall enter into an
underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this
Section 5, which managing underwriter shall be reasonably acceptable to the
Company. Such agreement shall be reasonably satisfactory in form and substance
to the Company, each Holder and such managing underwriters, and shall contain
such representations, warranties and covenants by the Company and such other
terms as are customarily contained in agreements of that type used by the
managing underwriter. The Holders shall be parties to any underwriting agreement
relating to an underwritten sale of their Registrable Securities and may, at
their option, require that any or all the representations, warranties and
covenants of the Company to or for the benefit of such underwriters shall also
be made to and for the benefit of such Holders. Such Holders shall not be
required to make any representations or warranties to or agreements with the
Company or the underwriters except as they may relate to such Holders and their
intended methods of distribution. Such Holders, however, shall agree to such
covenants and indemnification and contribution obligations for selling
stockholders as are customarily contained in agreements of that type used by the
managing underwriter. Further, such Holders shall execute appropriate custody
agreements and otherwise cooperate fully in the preparation of the registration
statement and other documents relating to any offering in which they include
securities pursuant to this Section 5. Each Holder shall also furnish to the
Company such information regarding itself, the Registrable Securities held by
it, and the intended method of disposition of such securities as shall be
reasonably required to effect the registration of the Registrable Securities.

                  5.4.5 Rule 144 Sale. Notwithstanding anything contained in
this Section 5 to the contrary, the Company shall have no obligation pursuant to
Sections 5.1 or 5.2 for the registration of Registrable Securities held by any
Holder (i) where such Holder would then be entitled to sell under Rule 144
within any three-month period (or such other period prescribed under Rule 144 as
may be provided by amendment thereof) all of the Registrable Securities then
held by such Holder, and (ii) where the number of Registrable Securities held by
such Holder is within the volume limitations under paragraph (e) of Rule 144
(calculated as if such Holder were an affiliate within the meaning of Rule 144).

                  5.4.6 Supplemental Prospectus. Each Holder agrees, that upon
receipt of any notice from the Company of the happening of any event 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 not misleading in light of the circumstances then existing, such Holder
will immediately discontinue disposition of Registrable Securities pursuant to
the Registration Statement covering such Registrable Securities until such
Holder's receipt of the copies of a supplemental or amended prospectus, and, if
so desired by the Company, such Holder shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate of
such destruction) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.

6.       Adjustments.

         6.1 Adjustments to Exercise Price and Number of Securities. The
Exercise Price and the number of Units underlying the Purchase Option shall be
subject to adjustment from time to time as hereinafter set forth:

                  6.1.1 Stock Dividends - Split-Ups. If after the date hereof,
and subject to the provisions of Section 6.4 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 thereof, the number of shares of Common Stock
underlying each of the Units purchasable hereunder shall be increased in
proportion to such increase in outstanding shares. In such case, the number of
shares of Common Stock, and the exercise price applicable thereto, underlying
the Warrants underlying each of the Units purchasable hereunder shall be
adjusted in accordance with the terms of the Warrants. For example, if the
Company declares a two-for-one stock dividend and at the time of such dividend
this Purchase Option is for the purchase of one Unit at $6.60 per whole Unit
(each Warrant underlying the Units is exercisable for $5.00 per share), upon
effectiveness of the dividend, this Purchase Option will be adjusted to allow
for the purchase of one Unit at $6.60 per Unit, each Unit entitling the holder
to receive two shares of Common Stock and four Warrants (each Warrant
exercisable for $2.50 per share).

                  6.1.2 Aggregation of Shares. If after the date hereof, and
subject to the provisions of Section 6.4, the number of outstanding shares of
Common Stock is decreased by a consolidation, combination or reclassification of
shares of Common Stock or other similar event, then, on the effective date
thereof, the number of shares of Common Stock underlying each of the Units
purchasable hereunder shall be decreased in proportion to such decrease in
outstanding shares. In such case, the number of shares of Common Stock, and the
exercise price applicable thereto, underlying the Warrants underlying each of
the Units purchasable hereunder shall be adjusted in accordance with the terms
of the Warrants.

                  6.1.3 Replacement of Securities upon Reorganization, etc. In
case of any reclassification or reorganization of the outstanding shares of
Common Stock other than a change covered by Section 6.1.1 or 6.1.2 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 property of the Company as an
entirety or substantially as an entirety in connection with which the Company is
dissolved, the Holder of this Purchase Option shall have the right thereafter
(until the expiration of the right of exercise of this Purchase Option) to
receive upon the exercise hereof, for the same aggregate Exercise Price payable
hereunder immediately prior to such event, 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, by a Holder of the number of shares of
Common Stock of the Company obtainable upon exercise of this Purchase Option and
the underlying Warrants immediately prior to such event; and if any
reclassification also results in a change in shares of Common Stock covered by
Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections
6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
similarly apply to successive reclassifications, reorganizations, mergers or
consolidations, sales or other transfers.

                                       8
<PAGE>

                  6.1.4 Changes in Form of Purchase Option. This form of
Purchase Option need not be changed because of any change pursuant to this
Section, and Purchase Options issued after such change may state the same
Exercise Price and the same number of Units as are stated in the Purchase
Options initially issued pursuant to this Agreement. The acceptance by any
Holder of the issuance of new Purchase Options reflecting a required or
permissive change shall not be deemed to waive any rights to an adjustment
occurring after the Commencement Date or the computation thereof.

         6.2      [Intentionally Omitted]

         6.3 Substitute Purchase Option. In case of any consolidation of the
Company with, or merger of the Company with, or merger of the Company into,
another corporation (other than a consolidation or merger which does not result
in any reclassification or change of the outstanding Common Stock), the
corporation formed by such consolidation or merger shall execute and deliver to
the Holder a supplemental Purchase Option providing that the holder of each
Purchase Option then outstanding or to be outstanding shall have the right
thereafter (until the stated expiration of such Purchase Option) to receive,
upon exercise of such Purchase Option, the kind and amount of shares of stock
and other securities and property receivable upon such consolidation or merger,
by a holder of the number of shares of Common Stock of the Company for which
such Purchase Option might have been exercised immediately prior to such
consolidation, merger, sale or transfer. Such supplemental Purchase Option shall
provide for adjustments which shall be identical to the adjustments provided in
Section 6. The above provision of this Section shall similarly apply to
successive consolidations or mergers.

         6.4 Elimination of Fractional Interests. The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
or Warrants upon the exercise of the Purchase Option, nor shall it be required
to issue scrip or pay cash in lieu of any fractional interests, it being the
intent of the parties that all fractional interests shall be eliminated by
rounding any fraction up to the nearest whole number of Warrants, shares of
Common Stock or other securities, properties or rights.

         7. Reservation and Listing. The Company shall at all times reserve and
keep available out of its authorized shares of Common Stock, solely for the
purpose of issuance upon exercise of the Purchase Options or the Warrants
underlying the Purchase Option, such number of shares of Common Stock or other
securities, properties or rights as shall be issuable upon the exercise thereof.
The Company covenants and agrees that, upon exercise of the Purchase Options and
payment of the Exercise Price therefor, all shares of Common Stock and other
securities issuable upon such exercise shall be duly and validly issued, fully
paid and non-assessable and not subject to preemptive rights of any stockholder.
The Company further covenants and agrees that upon exercise of the Warrants
underlying the Purchase Options and payment of the respective Warrant exercise
price therefor, all shares of Common Stock and other securities issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable
and not subject to preemptive rights of any stockholder. As long as the Purchase
Options shall be outstanding, the Company shall use its best efforts to cause
all (i) Units and shares of Common Stock issuable upon exercise of the Purchase
Options, (iii) Warrants issuable upon exercise of the Purchase Options and (iv)
shares of Common Stock issuable upon exercise of the Warrants included in the
Units issuable upon exercise of the Purchase Option to be listed (subject to
official notice of issuance) on all securities exchanges (or, if applicable on
the Nasdaq National Market, SmallCap Market, OTC Bulletin Board or any successor
trading market) on which the Units, the Common Stock or the Public Warrants
issued to the public in connection herewith may then be listed and/or quoted.

8.       Certain Notice Requirements.

         8.1 Holder's Right to Receive Notice. Nothing herein shall be construed
as conferring upon the Holders the right to vote or consent as a stockholder for
the election of directors or any other matter, or as having any rights
whatsoever as a stockholder of the Company. If, however, at any time prior to
the expiration of the Purchase Options and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the
Company shall give written notice of such event at least fifteen days prior to
the date fixed as a record date or the date of closing the transfer books for
the determination of the stockholders entitled to such dividend, distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale. Such notice shall
specify such record date or the date of the closing of the transfer books, as
the case may be. Notwithstanding the foregoing, the Company shall deliver to
each Holder a copy of each notice given to the other stockholders of the Company
at the same time and in the same manner that such notice is given to the
stockholders.

         8.2 Events Requiring Notice. The Company shall be required to give the
notice described in this Section 8 upon one or more of the following events: (i)
if the Company shall take a record of the holders of its shares of Common Stock
for the purpose of entitling them to receive a dividend or distribution payable
otherwise than in cash, or a cash dividend or distribution payable otherwise
than out of retained earnings, as indicated by the accounting treatment of such
dividend or distribution on the books of the Company, or (ii) the Company shall
offer to all the holders of its Common Stock any additional shares of capital
stock of the Company or securities convertible into or exchangeable for shares
of capital stock of the Company, or any option, right or warrant to subscribe
therefor, or (iii) a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

         8.3 Notice of Change in Exercise Price. The Company shall, promptly
after an event requiring a change in the Exercise Price pursuant to Section 6
hereof, send notice to the Holders of such event and change ("Price Notice").
The Price Notice shall describe the event causing the change and the method of
calculating same and shall be certified as being true and accurate by the
Company's President and Chief Financial Officer.

         8.4 Transmittal of Notices. All notices, requests, consents and other
communications under this Purchase Option shall be in writing and shall be
deemed to have been duly made when hand delivered, or mailed by express mail or
private courier service: (i) If to the registered Holder of the Purchase Option,
to the address of such Holder as shown on the books of the Company, or (ii) if
to the Company, to the following address or to such other address as the Company

9.       Miscellaneous.

         9.1 Amendments. The Company and EBC may from time to time supplement or
amend this Purchase Option without the approval of any of the Holders in order
to cure any ambiguity, to correct or supplement any provision contained herein
that may be defective or inconsistent with any other provisions herein, or to
make any other provisions in regard to matters or questions arising hereunder
that the Company and EBC may deem necessary or desirable and that the Company
and EBC deem shall not adversely affect the interest of the Holders. All other
modifications or amendments shall require the written consent of and be signed
by the party against whom enforcement of the modification or amendment is
sought.

         9.2 Headings. The headings contained herein are for the sole purpose of
convenience of reference, and shall not in any way limit or affect the meaning
or interpretation of any of the terms or provisions of this Purchase Option.

         10. Entire Agreement. This Purchase Option (together with the other
agreements and documents being delivered pursuant to or in connection with this
Purchase Option) constitutes the entire agreement of the parties hereto with
respect to the subject matter hereof, and supersedes all prior agreements and
understandings of the parties, oral and written, with respect to the subject
matter hereof.

         10.1 Binding Effect. This Purchase Option shall inure solely to the
benefit of and shall be binding upon, the Holder and the Company and their
permitted assignees, respective successors, legal representative and assigns,
and no other person shall have or be construed to have any legal or equitable
right, remedy or claim under or in respect of or by virtue of this Purchase
Option or any provisions herein contained.

         10.2 Governing Law; Submission to Jurisdiction. This Purchase Option
shall be governed by and construed and enforced in accordance with the laws of
the State of New York, without giving effect to conflict of laws. The Company
hereby agrees that any action, proceeding or claim against it arising out of, or
relating in any way to this Purchase Option shall be brought and enforced in the
courts of the State of New York or of the United States of America for the
Southern District of New York, and irrevocably submits to such jurisdiction,
which jurisdiction shall be exclusive. The Company hereby waives any objection
to such exclusive jurisdiction and that such courts represent an inconvenient
forum. Any process or summons to be served upon the Company may be served by
transmitting a copy thereof by registered or certified mail, return receipt
requested, postage prepaid, addressed to it at the address set forth in Section
8 hereof. Such mailing shall be deemed personal service and shall be legal and
binding upon the Company in any action, proceeding or claim. The Company and the
Holder agree that the prevailing party(ies) in any such action shall be entitled
to recover from the other party(ies) all of its reasonable attorneys' fees and
expenses relating to such action or proceeding and/or incurred in connection
with the preparation therefor.

         10.3 Waiver, Etc. The failure of the Company or the Holder to at any
time enforce any of the provisions of this Purchase Option shall not be deemed
or construed to be a waiver of any such provision, nor to in any way affect the
validity of this Purchase Option or any provision hereof or the right of the
Company or any Holder to thereafter enforce each and every provision of this
Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of
any of the provisions of this Purchase Option shall be effective unless set
forth in a written instrument executed by the party or parties against whom or
which enforcement of such waiver is sought; and no waiver of any such breach,
non-compliance or non-

                                       11
<PAGE>

fulfillment shall be construed or deemed to be a waiver of any other or
subsequent breach, non-compliance or non-fulfillment.

         10.4 Execution in Counterparts. This Purchase Option may be executed in
one or more counterparts, and by the different parties hereto in separate
counterparts, each of which shall be deemed to be an original, but all of which
taken together shall constitute one and the same agreement, and shall become
effective when one or more counterparts has been signed by each of the parties
hereto and delivered to each of the other parties hereto.

         10.5 Exchange Agreement. As a condition of the Holder's receipt and
acceptance of this Purchase Option, Holder agrees that, at any time prior to the
complete exercise of this Purchase Option by Holder, if the Company and EBC
enter into an agreement ("Exchange Agreement") pursuant to which they agree that
all outstanding Purchase Options will be exchanged for securities or cash or a
combination of both, then Holder shall agree to such exchange and become a party
to the Exchange Agreement.

         10.6 Underlying Warrants. At any time after exercise by the Holder of
this Purchase Option, the Holder may exchange his Warrants (with a $6.40
exercise price) for Public Warrants (with a $5.00 exercise price) upon payment
to the Company of the difference between the exercise price of his Warrant and
the exercise price of the Public Warrants.

                                WARRANT AGREEMENT

         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.

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.

                                       11
<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
under this Agreement without any further act.

         8.3.     Fees and Expenses of Warrant Agent.

                  8.3.1. Remuneration. The Company agrees to pay the Warrant
Agent reasonable remuneration for its services as such Warrant Agent hereunder
and will reimburse the Warrant Agent upon demand for all expenditures that the
Warrant Agent may reasonably incur in the execution of its duties hereunder.

                  8.3.2. Further Assurances. The Company agrees to perform,
execute, acknowledge, and deliver or cause to be performed, executed,
acknowledged, and delivered all such further and other acts, instruments, and
assurances as may reasonably be required by the Warrant Agent for the carrying
out or performing of the provisions of this Agreement.

         8.4.     Liability of Warrant Agent.

                  8.4.1. Reliance on Company Statement. Whenever in the
performance of its duties under this Warrant Agreement, the Warrant Agent shall
deem it necessary or desirable that any fact or matter be proved or established
by the Company prior to taking or suffering any action hereunder, such fact or
matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
statement signed by the President or Chairman of the Board of the Company and
delivered to the Warrant Agent. The Warrant Agent may rely upon such statement
for any action taken or suffered in good faith by it pursuant to the provisions
of this Agreement.

                  8.4.2. Indemnity. The Warrant Agent shall be liable hereunder
only for its own negligence, willful misconduct or bad faith. The Company agrees
to indemnify the Warrant Agent and save it harmless against any and all
liabilities, including judgments, costs and reasonable counsel fees, for
anything done or omitted by the Warrant Agent in the execution of this Agreement
except as a result of the Warrant Agent's negligence, willful misconduct, or bad
faith.

                  8.4.3. Exclusions. The Warrant Agent shall have no
responsibility with respect to the

                                       12
<PAGE>

validity of this Agreement or with respect to the validity or execution of any
Warrant (except its countersignature thereof); nor shall it be responsible for
any breach by the Company of any covenant or condition contained in this
Agreement or in any Warrant; nor shall it be responsible to make any adjustments
required under the provisions of Section 4 hereof or responsible for the manner,
method, or amount of any such adjustment or the ascertaining of the existence of
facts that would require any such adjustment; nor shall it by any act hereunder
be deemed to make any representation or warranty as to the authorization or
reservation of any shares of Common Stock to be issued pursuant to this
Agreement or any Warrant or as to whether any shares of Common Stock will when
issued be valid and fully paid and nonassessable.

         8.5. Acceptance of Agency. The Warrant Agent hereby accepts the agency
established by this Agreement and agrees to perform the same upon the terms and
conditions herein set forth and among other things, shall account promptly to
the Company with respect to Warrants exercised and concurrently account for, and
pay to the Company, all moneys received by the Warrant Agent for the purchase of
shares of the Company's Common Stock through the exercise of Warrants.
