    Re:
      Initial Public Offering

    


    Gentlemen:

    


    This
      letter agreement is being delivered to you in accordance with the Underwriting
      Agreement (the “Underwriting Agreement”) entered into by and among Advanced
      Technology Acquisition Corp., a Delaware corporation (the “Company”), CRT
      Capital Group LLC (“CRT”), and I-Bankers Securities, Inc. (“I-Bankers,” and
      together with CRT, the “Underwriters”), relating to an underwritten initial
      public offering (the “IPO”) of the Company’s units (the “Units”), each comprised
      of one share of the Company’s common stock, par value $0.0001 per share (the
“Common Stock”), and one warrant exercisable for one share of Common Stock (a
“Warrant”).

    


    In
      order
      to induce the Company and the Underwriters to enter into the Underwriting
      Agreement and to proceed with the IPO, and in recognition of the benefit that
      such IPO will confer upon the undersigned as a stockholder of the Company,
      and
      for other good and valuable consideration, the receipt and sufficiency of which
      are hereby acknowledged, the undersigned hereby agrees with the Company and
      the
      Underwriters as follows.

    


    The
      undersigned hereby agrees that, on a date that is within the five-day period
      following the date that is 45 days after the date of the Underwriting Agreement
      or, if earlier, the date the Underwriters terminate their Over-allotment Option
      (as defined in the Underwriting Agreement) pursuant to the terms of the
      Underwriting Agreement, the undersigned will forfeit to the Company, and the
      Company shall accept from the undersigned, at no cost, the number of shares
      of
      Common Stock determined by multiplying (A) a fraction, (x) the numerator of
      which is the number of Insider Shares held by the undersigned, and (y) the
      denominator of which is the number of Insider Shares held by all Insiders,
      by
      (B) 6,250,000 minus the product of (x) the sum of (i) the number of Units sold
      in the IPO and (ii) the number of Units, if any, sold in the IPO pursuant to
      the
      exercise by the Underwriters of their Over-allotment Option, and (y) 0.25,
      provided, however, that if this is a negative number, then no shares shall
      be
      forfeited.

    

      
        
           

        

        
           

          
            

          

        

        
           

        

      




    Furthermore,
      the undersigned hereby agrees that the aggregate number of shares to be
      forfeited by all Initial Stockholders (as such term is defined in the
      Registration Statement relating to the Company’s initial public offering) will
      be equal to the number of shares resulting from the calculation in (B) above.
      In
      the event that one or more of the Initial Stockholders do not sign this Letter
      Agreement, the aggregate number of shares to be forfeited by all Initial
      Stockholders who do sign this Letter Agreement will be equal to the number
      of
      shares resulting from the calculation in (B) above.
