    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. 

     

    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.

      Combination. The undersigned shall also be entitled to reimbursement from the
      Company for their out-of-pocket expenses incurred in connection with seeking
      and

      the
      undersigned or any Affiliate of the undersigned originates a Business
      Combination.
