                  Re:  INITIAL PUBLIC OFFERING

Gentlemen:

                  The undersigned director of ChinaGrowth South Acquisition
Corporation ("Company"), in consideration of Morgan Joseph & Co. Inc. ("Morgan
Joseph") 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 14 hereof):

                  1. 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 ("Claim") in or to any distribution of the Trust
Fund, except with respect to any of the IPO Shares, as defined herein, acquired
by the undersigned in connection with or following the IPO, and any remaining
net assets of the Company as a result of such liquidation 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. The undersigned agrees to indemnify
and hold harmless the Company 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

<PAGE>

whatsoever) which the Company may become subject as a result of any claim by any
vendor that is owed money by the Company for services rendered or products sold
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 (as defined in
the Letter of Intent).

                  2. 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 a
director or officer of the Company, subject to any pre-existing fiduciary and
contractual obligations the undersigned might have. The undersigned further
agrees not to become affiliated with any entity, including but not limited to a
blank check company, which is engaged in business activities similar to those
conducted by the Company until the earlier of completion of a Business
Combination or dissolution of the Trust Fund.

                  3. The undersigned acknowledges and agrees that the Company
will not consummate 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 that is reasonably acceptable to Morgan
Joseph which opinion stated that the Business Combination is fair to the
Company's shareholders from a financial perspective.

                  4. Neither the undersigned, any member of the family of the
undersigned, nor any affiliate of the undersigned ("Affiliate") 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, Global Vestor Capital Partners, 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 office space, utilities, administrative, technology and
secretarial services. 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 (including
possible payments to unaffiliated third parties for performance of due
diligence).

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

                  6. The undersigned agrees to be a director of the Company
until the earlier of the consummation by the Company of a Business Combination
or the liquidation of the Company. The undersigned's biographical information
furnished to the Company and Morgan Joseph and attached hereto as Exhibit A is
true and accurate in all respects, does not omit any material information with
respect to the undersigned's background and contains all of the information
required to be disclosed pursuant to Item 401 of Regulation S-K, promulgated
under the Securities Act of 1933. The undersigned's Questionnaire previously
furnished to the Company and Morgan Joseph is true and accurate in all respects.
The undersigned represents and warrants that:

<PAGE>

          (a) he is not 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) he has never 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) he has never 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.

                  7. The undersigned has full right and power, without violating
any agreement by which he is bound, to enter into this letter agreement and to
serve as a director of the Company.

                  8. The undersigned authorizes any employer, financial
institution, or consumer credit reporting agency to release to Morgan Joseph and
its legal representatives or agents (including any investigative search firm
retained by Morgan Joseph) any information they may have about the undersigned's
background and finances ("Information"). Neither Morgan Joseph nor its agents
shall be violating the undersigned's right of privacy in any manner in
requesting and obtaining the Information and the undersigned hereby releases
them from liability for any damage whatsoever in that connection.

                  9. In connection with the vote required to consummate a
Business Combination, the undersigned agrees that he will vote all ordinary
shares owned by him, either for or against a Business Combination, in a manner
determined by a majority of the public shareholders who vote at a special or
annual meeting called for the purpose of approving the Business Combination.
Further, the undersigned agrees that if he acquires ordinary shares following
the offering, he will vote such acquired shares in favor of a Business
Combination, despite the vote of the majority of public shareholders.

                  10. The undersigned will escrow his Insider Shares for the
period commencing on the Effective Date and ending one year from the date of the
Business Combination, subject to the terms of a Securities Escrow Agreement
which the Company will enter into with the undersigned and an escrow agent
acceptable to the Company.

                  11. The undersigned will escrow his founding directors
warrants purchased in a private placement concurrent with the IPO until
consummation of a Business Combination, subject to the terms of a Securities
Escrow Agreement which the Company will enter into with the undersigned and an
escrow agent acceptable to the Company.

<PAGE>

                  12. The undersigned agrees to not to resign (or advise the
Board that the undersigned declines to seek re-election to the Board of
Directors) from his position as director of the Company as set forth in the
Registration Statement without the prior consent of Morgan Joseph until the
earlier of the consummation by the Company of a Business Combination,
liquidation of the Trust Account, or the liquidation of the Company. The
undersigned acknowledges that the foregoing does not interfere with or limit in
any way the right of the Company to terminate the undersigned's employment at
any time (subject to other contractual rights the undersigned may have) nor
confer upon the undersigned any right to continue in the employ of Company.

                  13. This letter agreement shall be governed by and construed
and enforced in accordance with the laws of the State of New York, without
giving effect to conflicts of law principles that would result in the
application of the substantive laws of another jurisdiction. The undersigned
hereby (i) agrees that any action, proceeding or claim against him arising out
of or relating in any way to this letter agreement (a "Proceeding") shall be
brought and enforced in the courts of the State of New York of the United States
of America for the Southern District of New York, and irrevocably submits to
such jurisdiction, which jurisdiction shall be exclusive, (ii) waives any
objection to such exclusive jurisdiction and that such courts represent an
inconvenient forum and (iii) irrevocably agrees to appoint DLA Piper Rudnick
Gray Cary US LLP as agent for the service of process in the State of New York to
receive, for the undersigned and on his behalf, service of process in any
Proceeding. If for any reason such agent is unable to act as such, the
undersigned will promptly notify the Company and Morgan Joseph and appoint a
substitute agent acceptable to each of the Company and Morgan Joseph within 30
days and nothing in this letter will affect the right of either party to serve
process in any other manner permitted by law.

acquisition by merger, share capital exchange, asset or share acquisition,

THIS CERTIFIES THAT, for value received _________________________________]

is the registered holder of a Warrant or Warrants expiring ________,  2010 [FOUR
YEARS  FROM DATE OF  PROSPECTUS]  ("Warrant")  to  purchase  one fully  paid and
non-assessable  Ordinary  Share,  par value  US$.001  per share  ("Shares"),  of
ChinaGrowth North Acquisition Corporation, a company incorporated under the laws
of the Cayman  Islands  (the  "Company"),  for each  Warrant  evidenced  by this
Warrant  Certificate.  The Warrant  entitles the holder thereof to purchase from
the  Company,  commencing  on the  later of (i) the  Company's  completion  of a
capital stock exchange,  asset acquisition or other similar business combination
or (ii)  ______________,  200_, such number of Ordinary Shares of the Company at
the price of US$6.00 per share,  upon surrender of this Warrant  Certificate and
payment  of the  Warrant  Price at the  office or agency of the  Warrant  Agent,
American  Stock  Transfer & Trust Company (such payment to be made by check made
payable to the Warrant  Agent),  but only  subject to the  conditions  set forth
herein and in the Warrant  Agreement  between the  Company  and  American  Stock
Transfer  & Trust  Company.  In no event  shall  the  registered  holder of this
Warrant be entitled to receive a net-cash settlement,  shares of common stock or
other consideration in lieu of physical settlement in shares of the Company. The
Warrant  Agreement  provides  that upon the  occurrence  of  certain  events the
Warrant Price and the number of Warrant Shares purchasable hereunder,  set forth
on the face hereof,  may, subject to certain conditions,  be adjusted.  The term
Warrant  Price as used in this  Warrant  Certificate  refers  to the  price  per
Ordinary Share at which Ordinary Shares may be purchased at the time the Warrant
is exercised.

         This  Warrant may expire on the date first  above  written if it is not
exercised  prior to such date by the registered  holder pursuant to the terms of
the Warrant  Agreement  or if it is not  redeemed  by the Company  prior to such
date.

         No fraction of an Ordinary  Share will be issued upon any exercise of a
Warrant. If the holder of a Warrant would be entitled to receive a fraction of a
Share upon any exercise of a Warrant,  the Company  shall,  upon such  exercise,
round up to the nearest whole number the number of Ordinary  Shares to be issued
to such holder.

         Upon any exercise of the Warrant for less than the total number of full
Ordinary  Shares  provided for herein,  there shall be issued to the  registered
holder  hereof or the  registered  holder's  assignee a new Warrant  Certificate
covering  the  number of  Ordinary  Shares  for which the  Warrant  has not been
exercised.

         Warrant  Certificates,  when surrendered at the office or agency of the
Warrant  Agent by the  registered  holder  hereof in person or by attorney  duly
authorized  in  writing,  may be  exchanged  in the  manner  and  subject to the
limitations  provided  in the  Warrant  Agreement,  but  without  payment of any
service charge, for another Warrant Certificate or Warrant  Certificates of like
tenor and evidencing in the aggregate a like number of Warrants.

         Upon due  presentment  for  registration  of  transfer  of the  Warrant
Certificate  at the  office  or  agency  of the  Warrant  Agent,  a new  Warrant
Certificate  or  Warrant  Certificates  of  like  tenor  and  evidencing  in the
aggregate  a like  number  of  Warrants  shall be issued  to the  transferee  in
exchange for this Warrant  Certificate,  subject to the limitations  provided in
the Warrant  Agreement,  without  charge except for any  applicable tax or other
governmental charge.

         The  Company and the  Warrant  Agent may deem and treat the  registered
holder as the absolute owner of this Warrant  Certificate  (notwithstanding  any
notation of ownership or other writing  hereon made by anyone),  for the purpose
of any exercise hereof,  of any distribution to the registered  holder,  and for
all other  purposes,  and neither  the  Company  nor the Warrant  Agent shall be
affected by any notice to the contrary.

         Neither this Warrant  Certificate  nor any of the Warrant(s)  evidenced
hereby  itself  entitles  the  registered  holder  to  any of  the  rights  of a
shareholder of the Company.

         The Company reserves the right to call the Warrant at any time prior to
its  exercise,  with a notice of call in writing to the holders of record of the
Warrant,  giving  30 days'  notice of such  call at any time  after the  Warrant
becomes  exercisable  if the last sale price of the Ordinary  Shares has been at
least  US$11.50  per share on each of 20 trading  days within any 30 trading day
period  ending on the third  business  day prior to the date on which  notice of
such call is given.  The call price of the Warrants is to be US$.01 per Warrant.
Any Warrant  either not  exercised or tendered back to the Company by the end of
the date  specified  in the notice of call shall be canceled on the books of the
Company and have no further value except for the US$.01 call price.
