                  Re:  INITIAL PUBLIC OFFERING

Gentlemen:

                  The undersigned director of ChinaGrowth North 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 of the Company, subject to any pre-existing fiduciary and contractual
obligations the undersigned might have.

                  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 and is reasonably acceptable to Morgan
Joseph 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.

                  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 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.
