    Re: Initial
      Public Offering

    


    Ladies
      and Gentlemen:


     

    The
      undersigned officer, director and security holder of Stoneleigh Partners
      Acquisition Corp. (the “Company”), in consideration of HCFP/Brenner Securities
      LLC’s ("Brenner") willingness to underwrite an initial public offering of the
      securities of the Company (the “IPO”) and embarking on the IPO process, hereby
      agrees as follows (certain capitalized terms used herein are defined in
      paragraph 10 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 take all reasonable
      actions within his power to (i) cause the Trust Fund to be liquidated and
      distributed to the holders of the shares of Class B common stock sold in the
      Company’s IPO and (ii) liquidate as soon as reasonably practicable. The
      undersigned waives any and all right, title, interest or claim of any kind
      in or
      to any distribution of the Trust Fund as a result of such liquidation with
      respect to his Insider Securities (each a "Claim") and hereby waives any Claim
      he 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 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 contracted
      for
      or products sold, or by any target business, only in the event that such vendor,
      other person or target business did not execute an agreement waiving any right,
      title, interest or claim of any kind in or to any amounts held in the Trust
      Fund, and 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 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
      Trust Fund or until such time as the undersigned ceases to be an officer or
      director of the Company, subject to any pre-existing fiduciary 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
      reasonably acceptable to Brenner 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 or fees of any kind, including finder’s and consulting fees,
      prior to, or for services they rendered in order to effectuate, the Business
      Combination; provided that commencing on the Effective Date, PLM International
      Inc. (“Related Party”), shall be allowed to charge the Company $7,500 per month,
      representing an allocable share of Related Party’s overhead, 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. 

     

    5. Neither
      the undersigned, any member of the family of the undersigned, or 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 not to sell any of his Insider Securities until the Company's
      completion of a Business Combination.

     

    7. The
      undersigned agrees to be the Chief Financial Officer and Assistant Secretary
      of
      the Company and to serve as a Director of the Company until the earlier of
      the
      consummation by the Company of a Business Combination or the distribution of
      the
      Trust Fund. The undersigned’s biographical information furnished to the Company
      and Brenner and attached hereto as Exhibit A is true and accurate in all
