    Gentlemen:

    


    As a
condition to the consummation of the transactions contemplated by that certain
agreement (the “Put/Call
Agreement”), dated the date hereof, by and among the undersigned, North
Shore Acquisition Corp. (the “Company”), Barry J. Gordon,
Marc H. Klee, Robert Sroka, Arthur H. Goldberg, Harvey Granat, and Alan J.
Loewenstein (collectively, the “Sellers”), the undersigned
hereby agrees as follows (certain capitalized terms used herein are defined in
paragraph 11 hereof):

    


    1.           In
the event that the Company fails to consummate a Business Combination within 24
months from the effective date (“Effective Date”) of the
registration statement relating to the Company’s initial public offering of
securities (“IPO”), the
undersigned will (i) cause the trust fund established in connection with the
Company’s IPO (the “Trust
Fund”) 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 (“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 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) that 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.

    


    2.           In
order to minimize potential conflicts of interest that 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.

    


    3.           The
undersigned acknowledges and agrees that the Company will not consummate any
Business Combination that involves a company that is affiliated with any of the
Insiders unless the Company obtains an opinion from an independent investment
banking firm reasonably acceptable to EarlyBirdCapital, Inc., as representative
of the underwriters of the Company’s IPO (the “Underwriters”), that the
Business Combination is fair to the Company’s stockholders from a financial
perspective.


    
      
         


      

      
         


        
          

        

      

      
         


      

    

    


    4.           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 or in connection with the consummation
of the Business Combination. Notwithstanding the foregoing, the Company will be
allowed to enter into a services agreement with Capital Express Co., Ltd.
(“Related Party”) for
the Company’s use of Related Party’s offices, utilities and personnel. The
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
of the undersigned 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 of the undersigned originates a Business
Combination.

    


    6.           The
undersigned agrees to be the Chairman of the Board of Directors 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 the Underwriters 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 represents and warrants
that:

    


    (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

    (b) he
has never been convicted of or pleaded guilty to any crime (i) involving any

    (c) he
has never been suspended or expelled from membership in any securities or

    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 Chairman of the
Board of Directors of the Company.

    


    8.           The
undersigned hereby waives his right to exercise conversion rights with respect
to any shares of the Company’s common stock owned or to be owned by the
undersigned, directly or indirectly, and agrees that he will not seek conversion
with respect to such shares in connection with any vote to approve a Business
Combination.

    


    9.           In
the event that the Company does not consummate a Business Combination and must
liquidate and its remaining net assets are insufficient to complete such
liquidation, the undersigned agrees to advance such funds necessary to complete
such liquidation and agrees not to seek repayment for such
expenses.


    
      
         


      

      
         


        
          

        

      

      
         


      

    


    10.           This
letter agreement shall be governed by and construed and enforced in accordance

undersigned will promptly notify the Company and the Underwriters and appoint a
substitute agent acceptable to each of the Company within 30 days and nothing in
