    Re:
      Initial Public Offering

    

    Gentlemen:

    

    The
      undersigned officer and director of Advanced Technology Acquisition Corp.
      (“Company”), in consideration of CRT Capital Group LLC (“CRT”) 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 9 hereof): 

    

    1.
      If the
      Company solicits approval of its stockholders of a Business Combination, the
      undersigned will vote all Pre-IPO Shares and IPO Shares beneficially owned
      by it
      in accordance with the majority of the votes cast by the non-affiliated holders
      of the IPO Shares.

    

    2.
      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 shall take all reasonable
      actions within such person’s power to cause (i) the Company to dissolve and
      liquidate the Trust Account to holders of IPO Shares as soon as reasonably
      practicable, and after approval of the Company's stockholders of a plan of
      dissolution and distribution and subject to the requirements of the Delaware
      General Corporation Law (the “DGCL”), including voting for the adoption of a
      resolution by the Board, prior to such Termination Date, pursuant to Section
      275(a) of the DGCL, which shall deem the dissolution of the Corporation
      advisable and (b) cause to be prepared such notices as are required by said
      Section 275(a) of the DGCL as promptly thereafter as possible, and (ii) vote
      his
      shares in favor of any plan of dissolution and distribution recommended by
      the
      Company's board of directors. The undersigned hereby waives any and all right,
      title, interest or claim of any kind in or to any distribution of the Trust
      Account and any remaining net assets of the Company as a result of such
      liquidation with respect to his Pre-IPO Shares (“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 Account for any reason whatsoever. The undersigned hereby agrees
      that
      the Company shall be entitled to a reimbursement from the undersigned for any
      distribution of the Trust Account received by the undersigned in respect of
      such
      person’s Pre-IPO Shares. 

    

    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 initial stockholders unless the Company obtains an opinion from an
      independent investment banking firm that the business combination is fair to
      the
      Company’s stockholders from a financial point of view.

    

    4.
      Neither
      the undersigned, any member of the Immediate 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, provided that
      commencing on the Effective Date, LMS Nihul (“Related Party”), shall be allowed
      to charge the Company $10,000 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. The undersigned shall also be entitled
      to reimbursement from the Company for its reasonable out-of-pocket expenses
      incurred in connection with the organization of the Company, the IPO, and
      certain activities on behalf of the Company, such as identifying and
      investigating possible targets for our initial Business
      Combination.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    5.

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

    

    6.
      The
      undersigned agrees to serve as a director and Chief Executive Officer of the

      against the Trustee involving any claim, or in connection with any claim or
      demand which in any way arises out of or relates to this Agreement, the services
      of the Trustee hereunder, or the Property or any income earned from investment
      of the Property, except for expenses and losses resulting from the Trustee's
      gross negligence or willful misconduct. Promptly after the receipt by the
      Trustee of notice of demand or claim or the commencement of any action, suit
      or
      proceeding, pursuant to which the Trustee intends to seek indemnification under
      this paragraph, it shall notify the Company in writing of such claim
      (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the
      right to conduct and manage the defense against such Indemnified Claim,
      provided, that the Trustee shall obtain the consent of the Company with respect
      to the selection of counsel, which consent shall not be unreasonably withheld.
      The Trustee may not agree to settle any Indemnified Claim without the prior
      written consent of the Company unless such settlement includes a full release
      of
      the Company with respect to such Indemnified Claim. The Company may participate
      in such action with its own counsel; 

    

    (c)         Pay
      the
      Trustee an initial acceptance fee, an annual fee and a transaction processing
      fee for each disbursement made pursuant to 2(a) and 2(b) as set forth on
      Schedule A hereto, which fees shall be subject to modification by the parties
      from time to time. It is expressly understood that the Property shall not be
      used to pay such fees and further agreed that said transaction processing fee
      shall be deducted by the Trustee from the disbursements made to the Company
      pursuant to Section 2(b). The Company shall pay the Trustee the initial
      acceptance fee and first year’s fee at the consummation of the IPO and
      thereafter on the anniversary of the Effective Date. The Trustee shall refund
      to
      the Company the fee (on a pro rata basis) with respect to any period after
      the
      liquidation of the Trust Account. The Company shall not be responsible for
      any
      other fees or charges of the Trustee except as may be provided in
      paragraph 3(b) hereof (it being expressly understood that the Property
      shall not be used to make any payments to the Trustee under such
      paragraph);

    

    (d)        
      Provide
      to the Trustee any letter of intent, agreement in principle or definitive
      agreement for a Business Combination that is executed on or prior to the First
      Date; and

    

    (e)         In
      connection with any vote of the Company’s stockholders regarding a Business
      Combination, provide to the Trustee an affidavit or certificate of a firm
      regularly engaged in the business of soliciting proxies and/or tabulating
      stockholder votes (which firm may be the Trustee) verifying the vote of the
      Company’s stockholders regarding such Business Combination.

    

    4.            
      Limitations
      of Liability.
      The
      Trustee shall have no responsibility or liability to:

    

    (a)         
      Take
      any
      action with respect to the Property, other than as directed in paragraph 1
      hereof and the Trustee shall have no liability to any party except for liability
      arising out of its own gross negligence or willful misconduct;

    

    (b)         Institute
      any proceeding for the collection of any principal and income arising from,
      or
      institute, appear in or defend any proceeding of any kind with respect to,
      any
      of the Property unless and until it shall have received instructions from the
      Company given as provided herein to do so and the Company shall have advanced
      or
      guaranteed to it funds sufficient to pay any expenses incident
      thereto;

    

    (c)         
      Change
      the investment of any Property, other than in compliance with
      paragraph 1(c);

    

    (d)         Refund
      any depreciation in principal of any Property;

    

    (e)         Assume
      that the authority of any person designated by the Company to give instructions
      hereunder shall not be continuing unless provided otherwise in such designation,
      or unless the Company shall have delivered a written revocation of such
      authority to the Trustee;

    

    (f)         
      The
      other
      parties hereto or to anyone else for any action taken or omitted by it, or
      any
      action suffered by it to be taken or omitted, in good faith and in the exercise
      of its own best judgment, except for its gross negligence or willful misconduct.
      The Trustee may rely conclusively and shall be protected in acting upon any
      order, notice, demand, certificate, opinion or advice of counsel (including
      counsel chosen by the Trustee), statement, instrument, report or other paper
      or
      document (not only as to its due execution and the validity and effectiveness
      of
      its provisions, but also as to the truth and acceptability of any information
      therein contained) which is believed by the Trustee, in good faith, to be
      genuine and to be signed or presented by the proper person or persons. The
      Trustee shall not be bound by any notice or demand, or any waiver, modification,
      termination or rescission of this Agreement or any of the terms hereof, unless
      evidenced by a written instrument delivered to the Trustee signed by the proper
      party or parties and, if the duties or rights of the Trustee are affected,
      unless it shall give its prior written consent thereto;

      the correctness of the information set forth in the Registration Statement
      or to
      confirm or assure that any acquisition made by the Company or any other action
      taken by it is as contemplated by the Registration Statement; and

    

    (h)        
      Verify
      calculations, qualify or otherwise approve Company requests for distributions
      pursuant to Section 1(i), 2(a) or 2(b) above.

     

    5.            
      Termination.
      This
      Agreement shall terminate as follows:

    

    (a)        
      If
      the
      Trustee gives written notice to the Company that it desires to resign under
      this
      Agreement, the Company shall use its reasonable efforts to locate a successor
      trustee. At such time that the Company notifies the Trustee that a successor
      trustee has been appointed by the Company and has agreed to become subject
      to
      the terms of this Agreement, the Trustee shall transfer the management of the
      Trust Account to the successor trustee, including but not limited to the
      transfer of copies of the reports and statements relating to the Trust Account,
      whereupon this Agreement shall terminate, except with respect to Paragraph
      3(b);
      provided, however, that, in the event that the Company does not locate a
      successor trustee within ninety days of receipt of the resignation notice from
      the Trustee, the Trustee may submit an application to have the Property
      deposited with the United States District Court for the Southern District of
      New
      York and upon such deposit, the Trustee shall be immune from any liability
      whatsoever; or 

    

    (b)        
      At
      such
      time that the Trustee has completed the liquidation of the Trust Account in
      accordance with the provisions of paragraph 1(i) hereof, and distributed the
      Property in accordance with the provisions of the Termination Letter, this
      Agreement shall terminate except with respect to Paragraph 3(b).

    

    6.            
      Miscellaneous.

    

    (a)        
      The
      Company and the Trustee each acknowledge that the Trustee will follow the
      security procedures set forth below with respect to funds transferred from
      the
      Trust Account. Upon receipt of written instructions, the Trustee will confirm
      such instructions with an Authorized Individual at an Authorized Telephone
      Number listed on the attached Exhibit E. The Company and the Trustee will
      each restrict access to confidential information relating to such security
      procedures to authorized persons. Each party must notify the other party
      immediately if it has reason to believe unauthorized persons may have obtained
      access to such information, or of any change in its authorized personnel. In
      executing funds transfers, the Trustee will rely upon account numbers or other
      identifying numbers of a beneficiary, beneficiary's bank or intermediary bank,
      rather than names. The Trustee shall not be liable for any loss, liability
      or
      expense resulting from any error in an account number or other identifying
      number, provided it has accurately transmitted the numbers
      provided.

    

    (b)         This
      Agreement shall be governed by and construed and enforced in accordance with
      the
      laws of the State of Delaware, without giving effect to conflicts of law
      principles that would result in the application of the substantive laws of
      another jurisdiction. It may be executed in several original or facsimile
      counterparts, each one of which shall constitute an original, and together
      shall
      constitute but one instrument.

    

    (c)         
      This
      Agreement contains the entire agreement and understanding of the parties hereto
      with respect to the subject matter hereof. This Agreement or any provision
      hereof may only be changed, amended or modified by a writing signed by each
      of
      the parties hereto; provided, however, that no such change, amendment or
      modification may be made without the prior written consent of CRT. As to any
      claim, cross-claim or counterclaim in any way relating to this Agreement, each
      party waives the right to trial by jury.

    Re: Trust
      Account No. [____]- Termination Letter

    

    Gentlemen:

    

    Pursuant
      to paragraph 1(i) of the Investment Management Trust Agreement between Advanced
      Technology Acquisition Corp. (“Company”) and Continental Stock Transfer &
Trust Company (“Trustee”), dated as of __________, 2006 (“Trust Agreement”),
      this is to advise you that the Company has entered into an agreement (“Business
      Agreement”) with __________________ (“Target Business”) to consummate a business
      combination with Target Business (“Business Combination”) on or about
[insert
      date].
      The
      Company shall notify you at least 48 hours in advance of the actual date of
      the
      consummation of the Business Combination (“Consummation Date”).

    

    In
      accordance with the terms of the Trust Agreement, we hereby authorize you to
      commence liquidation of the Trust Account to the effect that, on the
      Consummation Date, all of funds held in the Trust Account will be immediately
      available for transfer to the account or accounts that the Company shall direct
      on the Consummation Date.

    

    On
      the
      Consummation Date (i) counsel for the Company shall deliver to you written
      notification that (a) the Business Combination has been consummated and (b)
      the
      provisions of Section 11-51-302(6) and Rule 51-3.4 of the Colorado Statute
      have
      been met, and (ii) the Company shall deliver to you (a) [an
      affidavit] [a certificate] of
      __________________, which verifies the vote of the Company’s stockholders in
      connection with the Business Combination and (b) written instructions with
      respect to the transfer of the funds held in the Trust Account (“Instruction
      Letter”). You are hereby directed and authorized to transfer the funds held in
      the Trust Account immediately upon your receipt of the counsel's letter and
      the
      Instruction Letter, in accordance with the terms of the Instruction Letter.
      Notwithstanding the foregoing, upon verification of receipt by you of the
      Instruction Letter, we hereby agree and acknowledge that the Property in the
      Trust Account shall be distributed as follows: (1) first, to CRT by wire
      transfer (or as otherwise directed by CRT) in immediately available funds,
      the
      aggregate amount of $4,000,000 (or up to $4,600,000, if CRT’s over-allotment
      option has been exercised), plus any interest accrued thereon; and (2)
      thereafter, to any other Beneficiary in accordance with the terms of the
      Instruction Letter. In the event that certain deposits held in the Trust Account
      may not be liquidated by the Consummation Date without penalty, you will notify
      the Company of the same and the Company shall direct you as to whether such
      funds should remain in the Trust Account and distributed after the Consummation
      Date to the Company. Upon the distribution of all the funds in the Trust Account
      pursuant to the terms hereof, the Trust Agreement shall be
      terminated.

    

    In
      the
      event that the Business Combination is not consummated on the Consummation
      Date
      described in the notice thereof and we have not notified you on or before the
      original Consummation Date of a new Consummation Date, then the funds held
      in
      the Trust Account shall be reinvested as provided in the Trust Agreement on
      the
      business day immediately following the Consummation Date as set forth in the
      notice.

    Pursuant
      to paragraph 1(i) of the Investment Management Trust Agreement between Advanced
      Technology Acquisition Corp. (“Company”) and Continental Stock Transfer &
Trust Company (“Trustee”), dated as of ___________, 2006 (“Trust Agreement”),
      this is to advise you that the Company has been unable to effect a Business
      Combination with a Target Company within the time frame specified in the
      Company’s Certificate of Incorporation, as described in the Company’s prospectus
      relating to its IPO and the Board of Directors of the Company has voted to
      dissolve the Company and liquidate the Trust Account.

    

    In
      accordance with the terms of the Trust Agreement, we hereby (a) certify to
      you
      that the provisions of Section 11-51-302(6) and Rule 51-3.4 of the Colorado
      Statute have been met and (b) authorize you to commence liquidation of the
      Trust
      Account as promptly as practicable to the stockholders of record on the
      Last Date (as defined in the Trust Agreement). You will notify the Company
      in
      writing as to when all of the funds in the Trust Account will be available
      for
      immediate transfer (“Transfer Date”) in accordance with the terms of the Trust
      Agreement and the Certificate of Incorporation of the Company. You shall
      commence distribution of such funds in accordance with the terms of the Trust
      Agreement and the Certificate of Incorporation of the Company and you shall
      oversee the distribution of the funds. Upon the distribution of all the funds
      in
      the Trust Account, your obligations under the Trust Agreement shall be
      terminated.
