      from
      the Borrower’s execution of the Seven Bar Purchase Agreement.

        -2-

      approve the supplements to the Schedules to the Loan Agreement set forth in
      Attachment 1 hereto. 

     

    Section
      5. Developments
      Prior to Closing of Seven Bar Acquisition.

     

    (a)
      Notice
      of Developments.
      

     

    From
      the
      date of this Agreement through the closing or earlier termination of the Seven
      Bar Purchase Agreement, the Borrower shall promptly notify the Administrative
      Agent in writing of any notice (a “Seller
      Breach Notice”)
      it may
      receive from the Seven Bar Seller of any development causing a breach of any
      of
      the representations and warranties in Sections 3 or 4 of the Seven Bar Purchase
      Agreement (attaching a copy of such Seller Breach Notice). Upon receipt of
      any
      such notice, the Administrative Agent, acting at the direction of the Required
      Lenders, may terminate this Agreement by written notice to the Borrower if,
      in
      the reasonable opinion of the Required Lenders, such development has
      had,
      or is
      reasonably expected to have, individually or in the aggregate,
      a
‘Material Adverse
      Effect’
(as such term is defined in the Seven Bar Purchase Agreement). The termination
      of this Agreement will result in the waiver set forth in Section 3(a) hereof
      and
      the approval set forth in Section 4 hereof being null and void.

     

    (b)
      Revisions

    If
      the
      Required Lenders fail to exercise the termination right pursuant to the
      foregoing paragraph (a) within six (6) Business Days after receiving written
      notice from the Borrower, the Required Lenders shall be deemed to have accepted
      that (i) such Seller Breach Notice shall be deemed to have amended the
      disclosure schedules to the Seven Bar Purchase Agreement and to have qualified
      the representations and warranties contained in the Seven Bar Stock Purchase
      Agreement for purposes of determining the accuracy of representations and
      warranties at the closing of the Seven Bar Acquisition, and (ii) the
      Borrower shall have the right to amend the supplements to the Schedules to
      the
      Loan Agreement set forth in Attachment 1 hereto as necessary to reflect the
      developments described in such Seller Breach Notice.

     

    Section
      6. No
      Further Waiver
      or Amendment.
      Except
      to the extent that provisions of the Loan Agreement or its Schedules are
      amended, waived or supplemented as expressly set forth in Sections 2, 3 and
      4
      hereof, the execution and delivery hereof shall
      not
      (a) operate as a modification or waiver of any right,
      power or
      remedy of the Financing Parties or the Collateral Agent under any of the Loan
      Documents, (b) cause a novation with respect to any of the Loan Documents,
      or (c) extinguish or terminate any obligations of the
      Borrower
      under the Loan Documents.

     

    Section
      7. Amendment
      Effective Date.
      Except
      for the waiver set forth in Section 3(b) above, this Agreement shall become
      effective on the first date (the “Amendment
      Effective Date”)
      on
      which the Administrative Agent shall have received all of the
      following:

      provision of this Agreement is held to be illegal, invalid or unenforceable,
      the
      legality, validity and enforceability of the remaining provisions of this
      Agreement shall not be affected or impaired thereby. The invalidity of a
      provision in a particular jurisdiction shall not invalidate or render

    Dear
      Sir
      or Madam,

     

    RE:
      Investor Contribution Agreement

     

    We
      refer
      to (i) the Loan Agreement dated as of September 27, 2007 by and among
      Atlantic Aviation FBO Inc. (the “Borrower”),
      the
      several banks and other financial institutions from time to time parties thereto
      as lenders (the “Lenders”),
      issuing bank or hedging banks, and DEPFA BANK plc as administrative agent (in
      that capacity, the “Administrative
      Agent”)
      (as
      amended, the “Loan
      Agreement”),
      (ii) the Stock Purchase Agreement dated as of December __, 2007 among Seven
      Bar Enterprises, Inc. (the “Seven
      Bar Seller”),
      as
      seller, the Borrower, as buyer, the A. Wade Black Trust, and A. Wade Black
      (the
“SPA”),
      and
      (iii) Waiver and Amendment Number Four to Loan Agreement, dated as of the
      date hereof, by and among the Borrower, the Lenders party thereto and the
      Administrative Agent (“Amendment
      No. 4”).
      All
      capitalized terms used but not otherwise defined herein shall have the meanings
      set forth in Appendix A to the Loan Agreement, and the rules of interpretation
      set forth in Appendix A to the Loan Agreement shall apply to this letter
      agreement. We hereby acknowledge that it is a condition precedent to the
      effectiveness of Amendment No. 4 that the Investor, the Borrower and the
      Administrative Agent shall have executed and delivered this letter
      agreement.

     

    1. Equity
      Contribution.
      The
      Investor hereby covenants to the Borrower and the Administrative Agent as
      follows:

     

    (a) The
      Investor shall cause the ‘Preliminary Purchase Price’ (as such term is defined
      in the SPA) to be paid in full accordance with the SPA solely from funds
      contributed by the Investor to the Borrower.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    (b) Promptly,
      but in any event within five (5) Business Days, after receiving notice from
      the
      Borrower or the Administrative Agent that the Borrower is required to make
      any
      other payments to the Seven Bar Seller pursuant to the SPA, including pursuant
      to Sections 2(h) (Post-Closing Adjustment to Preliminary Purchase Price), 8(c)
      (Indemnification Provisions for Seller’s Benefit), or 8(g) (Environmental
      Remedies) thereof, or pursuant to the Tax Matters Agreement (as such term is
      defined in the SPA), the Investor shall make additional equity contributions
      to
      the Borrower in an amount equal to any such required payments. 

     

    (c) The
      Investor shall pay all reasonable out-of-pocket expenses incurred by the
      Administrative Agent or the Borrower, including the fees, charges and
      disbursements of any counsel for the Administrative Agent or the Borrower,
      in
      connection with the enforcement, attempted enforcement or protection of their
      respective rights in connection with this letter agreement or any other Loan
      Document.

     

    2. Enforcement.
      The
      Investor acknowledges and agrees that this letter agreement is entered into
      for
      the benefit of the Borrower and the Administrative Agent, acting on behalf
      of
      the Financing Parties, and that the Administrative Agent, on behalf of the
      Financing Parties, shall have the right (but not the obligation) to proceed
      directly against the Investor to enforce any obligations of the Investor
      hereunder. 

     

    3. Limitation
      of Liability.
      The
      obligations of the Investor under this letter agreement are limited as set
      forth
      herein and shall in no way create any recourse, liability or obligation
      (contingent or otherwise) to or on the part of Investor or any of its Affiliates
      beyond the liabilities expressly set out in this letter agreement. No further
      liability and no promise of any additional commitments are to be inferred or
      implied. 

     

    4. Representations
      and Warranties.
      The
      Investor warrants and represents to the Borrower and the Administrative Agent
      as
      follows: 

     

    (a) The
      Investor is a duly organized, validly existing limited liability company
      organized and in good standing under the laws of the State of Delaware, and
      has
      all requisite power and authority to conduct its business and to own its
      property as now conducted or owned;

     

    (b) The
      execution, delivery and performance by the Investor of this letter agreement,
      and the performance of its obligations hereunder, are within the Investor’s
      limited liability company powers, have been duly authorized by all necessary
      action, and do not (i) contravene the Investor’s organizational documents, (ii)
      violate any Governmental Rule, or (iii) conflict with or result in the breach
      of, or constitute a default under, any contract, loan agreement, indenture,
      mortgage, deed of trust, lease or other instrument binding on or affecting
      the
      Investor or any of its property or assets; and

     

    (c) This
      letter agreement has been duly executed and delivered by a duly authorized
      representative of the Investor and constitutes a legal, valid and binding
      obligation of the Investor, enforceable against it in accordance with its terms,
      subject to applicable bankruptcy, insolvency, and similar laws affecting the
      enforcement of creditors’ rights generally and general principles of equity.

    This
      CONSENT AND AMENDMENT NUMBER FIVE TO LOAN AGREEMENT (this “Agreement”),
      dated
      as of January 31, 2008, among ATLANTIC AVIATION FBO INC., a Delaware corporation
      (the “Borrower”),
      ATLANTIC
      AVIATION FBO HOLDINGS LLC
      (formerly known as Macquarie FBO Holdings LLC), a Delaware limited liability
      company (the “Pledgor”),
      and
      the several banks and other financial institutions signatories hereto (the
      “Lender
      Parties”),
      and
      acknowledged by DEPFA BANK plc, as Administrative Agent (in such capacity,
      the
“Administrative
      Agent”).
      

    

    RECITALS

    

    A. The
      Borrower, the Lender Parties and the Administrative Agent are parties to the
      Loan Agreement dated as of September 27, 2007, by and among the Borrower, the
      several banks and other financial institutions from time to time parties thereto
      as lenders (the “Lenders”),
      issuing bank or hedging banks and the Administrative Agent (as amended, the
      “Loan
      Agreement”),
      pursuant to which the Lenders have agreed to provide certain loans to the
      Borrower for the purposes and upon the terms and conditions set forth
      therein.

     

    B. The
      Pledgor, the Borrower’s parent company, entered into that certain Share Pledge
      Agreement dated as of October 16, 2007 (the “Pledge
      Agreement”),
      by
      and between Pledgor and The Bank of New York, in its capacity as collateral
      agent for the benefit of the Secured Parties (the “Collateral
      Agent”),
      pursuant to which Pledgor, among other things, assigned, pledged and granted
      to
      the Collateral Agent, for the ratable benefit of the Secured Parties, a security
      interest in all of its respective right, title and interest in and to all of
      the
      issued and outstanding capital stock of the Borrower.

     

    C. The
      Pledgor has changed its name from “Macquarie FBO Holdings LLC” to “Atlantic
      Aviation FBO Holdings LLC” effective as of January 2, 2008, and amended the
      financing statement filed in connection with the Pledge Agreement (the
“Financing Statement”) to amend the “debtor’s” name on January 9, 2008, and
      provided a copy to the Administrative Agent. 

     

    D. The
      Borrower and Pledgor have requested that the Required Lenders consent to the
      change of name from “Macquarie FBO Holdings LLC” to “Atlantic Aviation FBO
      Holdings LLC” and waive any non-compliance with the Loan Documents arising out
      of not having amended the Financing Statement simultaneously with the
      effectiveness of the name change. 

     

    E. The
      Borrower has also requested that the Required Lenders amend Exhibit E to the
      Loan Agreement, “Form of Financial Ratio Certification” to be in the form
      attached hereto as Attachment 1.

     

    F.
       The
      Lender Parties are willing to provide the requested waivers and agree to the
      requested amendment, all subject to and upon the terms as set forth
      herein.

      THEREFORE, the parties hereto hereby agree as follows:

     

    Section
      1. Definitions
      and Rules of Interpretation.
      All
      capitalized terms used but not defined in this Agreement shall have the
      respective meanings specified in the Loan Agreement. The rules of interpretation
      set forth in Appendix A to the Loan Agreement shall apply to this Agreement,

    Section
      2. Amendment
      to Exhibit E to the Loan Agreement.
      Exhibit
      E to the Loan Agreement, “Form of Financial Ratio Certification” is hereby
      deleted and replaced in its entirety with the “Form of Financial Ratio
      Certification” attached hereto as Attachment 1.

     

    Section
      3. Consent.
      

     

    (a) Each
      Required Lender hereby consents to the change of name of Pledgor from “Macquarie
      FBO Holdings LLC” to “Atlantic Aviation FBO Holdings LLC” to be effective as of
      the date of the name change and waives any non-compliance with any Loan Document
      arising from Pledgor’s failure to amend the Financing Statement simultaneously
      with the effectiveness of the name change (the “Consent”).

     

    (b) The
      Consent set forth herein shall be limited precisely as provided for herein
      to
      the provisions expressly referred to herein and shall not be deemed to be a
      waiver of, amendment of, consent to or modification of any other term or
      provision of the Loan Agreement, the Pledge Agreement, or any term or provision
      of any other Loan Document.

      Pledge Agreement are amended, waived or supplemented as expressly set forth
      in
      Sections 2 and 3 hereof, the execution and delivery hereof shall
      not
      (a) operate as a modification or waiver of any right,
      power or
      remedy of the Financing Parties or the Collateral Agent under any of the Loan
      Documents, (b) cause a novation with respect to any of the Loan Documents,
      or (c) extinguish or terminate any obligations of the
      Borrower
      under the Loan Documents or the Pledgor under the Pledge Agreement.

     

    Section

      6. Severability.
      If any
      provision of this Agreement is held to be illegal, invalid or unenforceable,
      the
      legality, validity and enforceability of the remaining provisions of this
      Agreement shall not be affected or impaired thereby. The invalidity of a
      provision in a particular jurisdiction shall not invalidate or render
      unenforceable such provision in any other jurisdiction.

      headings in this Agreement have been included herein for convenience of
