                  Re:      Initial Public Offering

Gentlemen:

         The  undersigned  stockholder,  officer and  director of Chardan  China
Acquisition Corp. III ("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 12 hereof):

         1. If the Company  solicits  approval of its stockholders of a Business
Combination,  the  undersigned  will  vote all  Insider  Shares  owned by him 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), the undersigned will (i) cause
the Trust  Fund (as  defined  in the  Letter of  Intent)  to be  liquidated  and
distributed  to the holders of IPO Shares and (ii) take all  reasonable  actions
within  his  power to cause  the  Company  to  liquidate  as soon as  reasonably
practicable. The undersigned 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 his
Insider Shares ("Claim") and hereby waives any Claim the undersigned 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.  In the event of the  liquidation of the Trust Fund, the undersigned
agrees to  indemnify  and hold  harmless  the  Company,  pro rata with the other
directors of the Company and several individuals  affiliated with companies they
are associated with based on the number of Insider Shares  beneficially owned by
each such individual,  against any and all loss,  liability,  claims, damage and
expense  whatsoever  (including,  but not limited to, any and all legal or other
expenses  reasonably  incurred in investigating,  preparing or defending against
any litigation,  whether pending or threatened,  or any claim  whatsoever) which
the Company  may become  subject as a result of any claim by any vendor or other
person who is owed money by the Company for services  rendered or products  sold
or contracted for, or by any target  business,  but only to the extent necessary
to ensure that such loss,  liability,  claim,  damage or expense does not reduce
the amount in the Trust Fund.

         3. In order to minimize potential conflicts of interest which may arise
from multiple affiliations, the undersigned agrees to present to the Company for
its  consideration,  prior to  presentation  to any other person or entity,  any
suitable opportunity to acquire an operating business,  until the earlier of the
consummation  by the Company of a Business  Combination,  the liquidation of the
Company  or until  such  time as the  undersigned  ceases  to be an  officer  or
director of the Company,  subject to any pre-existing  fiduciary and contractual
obligations the undersigned might have.

         4. The  undersigned  acknowledges  and agrees that the Company will not
consummate any Business Combination which involves a company which is affiliated

independent  investment  banking  firm  reasonably  acceptable  to EBC  that the
business  combination  is fair to the  Company's  stockholders  from a financial
perspective.

         5.  Neither  the   undersigned,   any  member  of  the  family  of  the
undersigned, nor any affiliate ("Affiliate") of the undersigned 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
commencing on the Effective Date, Chardan Capital, LLC ("Related Party"),  shall
be allowed to charge the Company an allocable share of Related Party's overhead,
up to $7,500  per  month,  to  compensate  it for the  Company's  use of Related
Party's  offices,  utilities and  personnel.  Related Party and the  undersigned
shall also be entitled to reimbursement from the Company for their out-of-pocket
expenses  incurred  in  connection  with  seeking  and  consummating  a Business
Combination.
