    b. The
      definition of “Revised Base Case Projections” in Section
      1.1
      of the
      Loan Agreement is hereby deleted and replaced in its entirety with the
      following:

      Base Case Projections”
means,
      updated Base Case Projections, reflecting any changes thereto as a consequence
      of the Revised Use Agreement Termination Date.

     

    c. The
      definition of “Revised Use Agreement Termination Date” in Section
      1.1
      of the
      Loan Agreement is hereby deleted and replaced in its entirety with the
      following:

     

    “Revised
      Use Agreement Termination Date”
means,
      the date to which the term of the Use Agreement is extended beyond December
      31,
      2020, if such extension occurs.

     

    d. The
      mandatory prepayment provision in Section
      2.9(c)(viii)
      of the
      Loan Agreement is hereby deleted and replaced in its entirety with the
      following:

     

    “If
      during any fiscal year of the Borrower, the amount of Net Contract Termination
      Proceeds for such fiscal year exceeds $1,000,000, the Borrower shall, promptly
      after the contract termination, cancellation or non-renewal which results in
      such an excess or an increase in such an excess, prepay the Loans in an amount
      equal to 100% of the Net Contract Termination Proceeds for such fiscal year.
      The
      Borrower shall not be obligated to make a prepayment under this Section
      2.9(c)(viii)
      if and
      to the extent that 

     

    (A)
      no
      Lock-Up Period is in effect,

     

    (B)
      the
      Borrower makes a representation in writing to the Administrative Agent at the
      time the relevant Loan Party or Subsidiary receives such Net Contract
      Termination Proceeds that it or another Loan Party intends to reinvest such
      proceeds (1) within the same line of business which the relevant Loan Party
      is
      currently engaged, (2) within the United States of America, and (3) exclusively
      in Growth Capital Expenditures; and 

     

    (C)
      the
      Borrower makes a representation in writing to the Administrative Agent within
      90
      days of the relevant Loan Party or Subsidiary receiving such Net Contract
      Termination Proceeds that (1) it or another Loan Party has allocated such
      proceeds to specified and described Growth Capital Expenditure project(s),
      (2)
      it is reasonable to expect that such reinvestment shall generate future annual
      revenues equal to at least 90% of those generated in the prior fiscal year
      by
      the terminated, cancelled or non-renewed contract giving rise to such proceeds,
      and (3) it is reasonable to expect that such annual revenue amounts shall be
      reached within two (2) years from the date of such reinvestment.

     

    Any
      Net
      Contract Termination Proceeds in excess of $1,000,000 retained by the Borrower
      but not actually reinvested in a manner consistent with the representations
      of
      the Borrower and this Section
      2.9(c)(viii)
      within
      such time period and subject to such conditions shall at that time immediately
      be used to prepay the Loans in accordance with the first sentence of this
Section
       2.9(c)(viii).”

      hereto.

      Further Waiver or Amendment.
      Except
      to the extent that provisions of the Loan Agreement are amended as expressly
      set
      forth in Section
      2
      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.

      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.

     

    Section
      6. Headings.
      The
      headings in this Agreement have been included herein for convenience of
      reference only, are not part of this Agreement, and shall not be taken into

      This
      Agreement comprises the complete and integrated agreement of the parties hereto
      on the subject matter hereof and supersedes all prior agreements, written or

      8. Counterparts.
      This
      Agreement may be executed by one or more of the parties hereto on any number
      of
      separate counterparts, and all of said counterparts taken together shall be

    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 Membership Purchase Agreement dated as of November [__], 2007 by
      and among the sellers named therein (the “Rifle
      Sellers”)
      and
      the Borrower, as buyer (the “MPA”),
      and
      (iii) Amendment Number Three to Loan Agreement, dated as of the date
      hereof, by and among the Borrower, the Lenders party thereto and the
      Administrative Agent (“Amendment
      No. 3”).
      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. 3 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) 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
      payments to the Rifle Sellers pursuant to the MPA, including pursuant to
      Sections 2.3 (Working Capital Adjustments) or 12.2 (Indemnification by Buyer)
      thereof, or pursuant to the promissory note issued pursuant to Section
      2.2(a)(ii) thereof, the Investor shall make additional equity contributions
      to
      the Borrower in an amount equal to any such required payments.;

      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.
