            Re:   Initial Public Offering

Gentlemen:

            SUJG, Inc. ("SUJG"), a stockholder of Chardan China Acquisition
Corp. II ("Company"), in consideration of EarlyBirdCapital, Inc. ("EBC")
entering into a letter of intent ("Letter of Intent") to underwrite an initial
public offering of the securities of the Company ("IPO") and embarking on the
IPO process, hereby agrees as follows (certain capitalized terms used herein are
defined in paragraph 9 hereof):

            1.  If  the  Company  solicits  approval  of its  stockholders  of a
Business  Combination,  SUJG  will  vote  all  Insider  Shares  owned  by  it in
accordance with the majority of the votes cast by the holders of the IPO Shares.

            2. In the event  that the  Company  fails to  consummate  a Business
Combination  within 18 months from the effective date ("Effective  Date") of the
registration statement relating to the IPO (or 24 months under the circumstances
described  in the  prospectus  relating to the IPO),  SUJG will vote all Insider
Shares owned by it in favor of the Company's decision to liquidate. Each of SUJG
and each  officer,  director  or  controlling  person of SUJG  (each a  "Control
Person") hereby waives any and all right,  title,  interest or claim of any kind
in or to any  distribution of the Trust Fund and any remaining net assets of the
Company  as a result of such  liquidation  with  respect to its  Insider  Shares
("Claim")  and hereby waives any Claim either may have in the future as a result
of, or arising out of, any contracts or agreements with the Company and will not
seek recourse against the Trust Fund for any reason whatsoever.



            3.  Neither  SUJG,  any  Control  Person,  any family  member of any
Control Person,  nor any affiliate  ("Affiliate")  of SUJG or any Control Person
will submit to the Company for  consideration,  or vote for the approval of, any
Business  Combination  which involves a company which is affiliated  with any of
the  Insiders  unless  the  Company  obtains  an  opinion  from  an  independent
investment  banking  firm  reasonably   acceptable  to  EBC  that  the  business
combination is fair to the Company's stockholders from a financial perspective.

            4.  Neither  SUJG,  any  Control  Person,  any family  member of any
Control Person, nor any Affiliate of SUJG or any Control Person will be entitled
to receive and will not accept any  compensation  for  services  rendered to the
Company prior to the  consummation  of the Business  Combination;  provided that
SUJG  (and  each  Control  Person  on  behalf  of  SUJG)  shall be  entitled  to
reimbursement  from the  Company  for its  out-of-pocket  expenses  incurred  in
connection with seeking and consummating a Business Combination.

            5.  Neither  SUJG,  any  Control  Person,  any family  member of any
Control Person, nor any Affiliate of SUJG or any Control Person will be entitled
to receive or accept a finder's fee or any other compensation in the event SUJG,
any Control Person,  any family member of any Control Person or any Affiliate of
SUJG or any Control Person originates a Business Combination.

            6. SUJG will  escrow its  Insider  Shares for the three year  period
commencing  on the  Effective  Date  subject  to the  terms  of a  Stock  Escrow
Agreement  which the  Company  will  enter  into  with SUJG and an escrow  agent
acceptable to the Company.

            7. SUJG's Questionnaire furnished to the Company and EBC and annexed
as Exhibit A hereto is true and accurate in all respects.  SUJG  represents  and
warrants that:

            (a) no Control  Person is subject  to or a  respondent  in any legal
action for, any  injunction,  cease-and-desist  order or order or stipulation to
desist  or  refrain  from  any  act or  practice  relating  to the  offering  of
securities in any jurisdiction;

            (b) no Control  Person has ever been  convicted of or pleaded guilty
to any  crime  (i)  involving  any  fraud  or  (ii)  relating  to any  financial
transaction or handling of funds of another person,  or (iii)  pertaining to any
dealings in any  securities  and he is not  currently  a  defendant  in any such
criminal proceeding; and

            (c) no  Control  Person has ever been  suspended  or  expelled  from
membership in any  securities or  commodities  exchange or  association or had a
securities or commodities license or registration denied, suspended or revoked.

            8. SUJG has full right and power, without violating any agreement by
which he is bound, to enter into this letter agreement.




            9.  As used  herein,  (i) a  "Business  Combination"  shall  mean an
acquisition  by merger,  capital  stock  exchange,  asset or stock  acquisition,
reorganization  or otherwise,  of an operating  business;  (ii) "Insiders" shall
mean all officers,  directors and stockholders of the Company  immediately prior
to the IPO; (iii) "Insider  Shares" shall mean all of the shares of Common Stock
of the Company owned by an Insider prior to the IPO; and (iv) "IPO Shares" shall
mean the shares of Common Stock issued in the Company's IPO.
