      Borrowing, the Administrative Agent may assume that such Term Loan Lender
      will make such amount available to the Administrative Agent on such date
      in accordance with Section 2.1(b)(ii) and may, in reliance upon such
      assumption, make available to the Borrower a corresponding amount. If a
      Term Loan Lender has not in fact made its share of the applicable Term
      Loan Borrowing available to the Administrative Agent, such Term Loan
      Lender shall forthwith pay to the Administrative Agent on demand such
      corresponding amount with interest thereon, for each day from and
      including the date such amount is made available to the Borrower to but
      excluding the date of payment to the Administrative Agent, at the Federal
      Funds Rate. If such Term Loan Lender does not pay such amount within three
      (3) Business Days after the date of such Term Loan Borrowing, the
      Administrative Agent may make a demand therefor from the Borrower, and the
      Borrower shall, without limitation of the Borrower's rights against the
      defaulting Lender, pay such amount to the Administrative Agent, together
      with interest thereon from the date such amount was made available to the
      Borrower at the interest rate per annum applicable to the Term Loans
      advanced on the date of such Term Loan Borrowing. A notice of the
      Administrative Agent submitted to any Term Loan Lender or the Borrower
      with respect to any amounts owing under this paragraph shall be conclusive
      in the absence of manifest error.

                  (iv) The failure of any Term Loan Lender to make any Term Loan
      required to be made by it shall not relieve any other Term Loan Lender of
      its obligations hereunder; provided that the Term Loan Commitments of the
      Term Loan Lenders are several and no Term Loan Lender shall be responsible
      for any other Term Loan Lender's failure to make Term Loans as required
      herein.

      Section 2.2. Revolving Loan Facility.

            (a) Revolving Loan Commitments. Subject to the terms and conditions
set forth herein, the Revolving Loan Lender agrees to make loans (each, a
"REVOLVING LOAN") to the Borrower from time to time during the Revolving Loan
Commitment Period in such amounts as the Borrower may request under this Section
2.2 (and thereafter to make additional Revolving Loans to reimburse the Issuing
Bank for Drawings under Letters of Credit as provided in Section 2.13); provided
that the sum of (A) the aggregate principal amount outstanding of all Revolving
Loans made by the Revolving Loan Lender after giving effect to all prepayment
and repayments thereof and (B) the aggregate outstanding Letter of Credit Usage
shall not exceed the

                                       3

<PAGE>

Revolving Loan Commitment at any given time. Within the foregoing limits, and
subject to the other terms and conditions hereof, the Borrower may borrow, repay
and reborrow Revolving Loans until the Revolving Loan Commitment Termination
Date.

            (b) Revolving Loan Borrowing Procedures.

                  (i) To request a Revolving Loan Borrowing (other than a
      Borrowing to reimburse the Issuing Bank in respect of a Drawing), the
      Borrower shall deliver to the Administrative Agent an irrevocable
      Revolving Loan Borrowing Request in the form of Exhibit B-1, appropriately
      completed and duly signed by a Responsible Officer of the Borrower, which
      Revolving Loan Borrowing Request shall specify:

                  (A) the aggregate amount of the requested Revolving Loan
            Borrowing (which shall be not less than $100,000 and shall be an
            integral multiple of $50,000);

                  (B) the proposed date of such Revolving Loan Borrowing, which
            shall be a Business Day; and

                  (C) whether the requested Revolving Loan Borrowing is to
            consist of Base Rate Revolving Loans or LIBOR Revolving Loans and,
            if the requested Revolving Loan Borrowing consists of a LIBOR
            Revolving Loan, the initial Interest Period selected by the Borrower
            for such Revolving Loan in accordance with Section 2.4 of this
            Agreement.

Each Revolving Loan Borrowing Request for a Revolving Loan Borrowing consisting
of LIBOR Revolving Loans must be received by the Administrative Agent not later
than 11:00 a.m., New York City time, three (3) Business Days before the date of
such proposed Revolving Loan Borrowing, and each Revolving Loan Borrowing
Request for a Revolving Loan Borrowing consisting of Base Rate Revolving Loans
must be received by the Administrative Agent not later than 11:00 a.m., New York
City time, one (1) Business Day before the date of (or, if agreed to in writing
by the Revolving Loan Lender, on the date of) such proposed Revolving Loan
Borrowing. If no election as to the Type of Revolving Loan Borrowing is
specified in the applicable Revolving Loan Borrowing Request, then the requested
Revolving Loan Borrowing shall consist of Base Rate Revolving Loans. Each
Revolving Loan Borrowing shall be comprised entirely of Base Rate Revolving
Loans or LIBOR Revolving Loans, as the Borrower may request in accordance
herewith. The procedures specified in this paragraph shall not apply to any
Revolving Loan Borrowing with respect to a Drawing under a Letter of Credit
issued pursuant to Section 2.13.

                  (ii) Promptly following receipt of a Revolving Loan Borrowing
      Request in accordance with this Section 2.2(b), the Administrative Agent
      shall advise the Revolving Loan Lender of the details thereof and of the
      amount of the Revolving Loan Lender's Loan to be made pursuant to the
      requested Revolving Loan Borrowing. The Revolving Loan Lender shall make
      the Revolving Loan to be made by it hereunder on the proposed date thereof
      by wire transfer of immediately available funds by 12:00 noon, New York
      City time, to the account of the Administrative Agent most recently
      designated

                                       4

<PAGE>

      by it for such purpose by notice to the Revolving Loan Lender. Upon
      satisfaction of the applicable conditions set forth in Section 4.2, the
      Administrative Agent shall make such Revolving Loans available to the
      Borrower by 2:00 p.m., New York City time, by wire transfer of such funds
      in accordance with instructions reasonably acceptable to the
      Administrative Agent provided by the Borrower. Notwithstanding the
      foregoing, if, at the time of the Borrowing of such Revolving Loan, a
      Default or Event of Default has occurred and is continuing and the
      Required Lenders have provided notice to the Administrative Agent and the
      Revolving Loan Lender that the Revolving Loans may not be made while such
      Default or Event of Default is continuing, the Administrative Agent shall
      not make such Revolving Loans available to the Borrower. The Revolving
      Loan Lender shall make the sole determination as to whether the applicable
      conditions to the obligation of the Revolving Loan Lender to make
      Revolving Loans set forth in Section 4.2 have been satisfied.

                  (iii) Unless the Administrative Agent shall have been notified
      in writing by the Revolving Loan Lender prior to the proposed date of a
      Revolving Loan Borrowing that the Revolving Loan Lender will not make
      available to the Administrative Agent such Revolving Loan Borrowing, the
      Administrative Agent may assume that the Revolving Loan Lender will make
      such amount available to the Administrative Agent on such date in
      accordance with Section 2.1(b)(ii) and may, in reliance upon such
      assumption, make available to the Borrower a corresponding amount. If the
      Revolving Loan Lender has not in fact made the Revolving Loan available to
      the Administrative Agent, the Revolving Loan Lender shall forthwith pay to
      the Administrative Agent on demand such corresponding amount with interest
      thereon, for each day from and including the date such amount is made
      available to the Borrower to but excluding the date of payment to the
      Administrative Agent, at the Federal Funds Rate. If the Revolving Loan
      Lender does not pay such amount within three (3) Business Days after the
      date of such Revolving Loan Borrowing, the Administrative Agent may make a
      demand therefor from the Borrower, and the Borrower shall, without
      limitation of the Borrower's rights against the defaulting Lender, pay
      such amount to the Administrative Agent, together with interest thereon
      from the date such amount was made available to the Borrower at the
      interest rate per annum applicable to the Revolving Loans advanced on the
      date of such Revolving Loan Borrowing. A notice of the Administrative
      Agent submitted to the Revolving Loan Lender or the Borrower with respect
      to any amounts owing under this paragraph shall be conclusive in the
      absence of manifest error.

            (c) Conversion of Revolving Loans. Subject to Section 3.5, the
Borrower may convert any Revolving Loan Borrowing from one Type of Revolving
Loan Borrowing to the other Type; provided that no Base Rate Revolving Loan may
be converted into a LIBOR Revolving Loan after the occurrence and during the
continuance of an Event of Default; provided, further, that any conversion of a
LIBOR Revolving Loan on any day other than the last day of the Interest Period
therefor shall be subject to the payments required under Section 3.5. To request
a conversion of a Revolving Loan Borrowing, the Borrower shall deliver to the
Administrative Agent a Notice of Revolving Loan Conversion in the form of
Exhibit B-2, appropriately completed and duly executed by a Responsible Officer
of the Borrower, which Notice of Revolving Loan Conversion shall specify:

                                       5

<PAGE>

                  (i) the Revolving Loan Borrowing which is to be converted;

                  (ii) the Type of Revolving Loan Borrowing into which such
      Revolving Loan Borrowing is to be converted; and

                  (iii) the proposed date of the requested conversion, which
      shall be a Business Day.

      Each Notice of Revolving Loan Conversion must be received by the
Administrative Agent not later than 11:00 a.m., New York City time, three (3)
Business Days before the date of the requested conversion (and one (1) Business
Day before the date of conversion, in the case of a conversion to a Base Rate
Revolving Loan).

      Section 2.3. Interest.

            (a) Each LIBOR Loan shall bear interest during each Interest Period
at a rate per annum equal to LIBOR for such Interest Period plus the Applicable
Margin. Each Base Rate Revolving Loan shall bear interest at the Base Rate plus
the Applicable Margin.

            (b) Notwithstanding the foregoing, if any principal of or interest
on any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to 2% plus the highest rate applicable to the Loans as provided
in the above paragraph (a) of this Section 2.3 or if no Loans are then
outstanding, 4% plus the Base Rate. Accrued and unpaid interest on past due
amounts shall be due and payable on demand.

            (c) Accrued interest on each Loan shall be payable in arrears on
each Interest Payment Date for such Loan and at such other times as may be
specified herein.

            (d) All interest under this Section 2.3 shall be computed on the
basis of a year of 360 days, except that interest computed by reference to the
Base Rate at times when the Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day). The applicable Base Rate or LIBOR shall
be determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error.

      Section 2.4. Interest Periods.

            (a) Subject to paragraphs (b) and (c) below, the Borrower shall
select the initial Interest Period for each LIBOR Loan in the relevant Borrowing
Request and shall select each subsequent Interest Period for such LIBOR Loan in
an irrevocable notice received by the Administrative Agent not later than 11:00
a.m., New York City time, three (3) Business Days before the start of that
Interest Period; provided that if an Event of Default has occurred and is
continuing at such time, in the discretion of the Administrative Agent such
Interest Period shall have a period of one (1) month.

                                       6

<PAGE>

            (b) The Term Loans shall at any given time be subject to a single
Interest Period provided that the initial Interest Period with respect to the
Borrowing of Trajen Acquisition Term Loans will commence on the date of such
Borrowing and end on the same day as the current Interest Period for the
Refinancing Term Loans previously advanced and, on the last day of such Interest
Period, such Trajen Acquisition Term Loans shall be consolidated with the
Refinancing Term Loans, and the Trajen Acquisition Term Loans and Refinancing
Term Loans will thereafter have the same Interest Period. The initial Interest
Period for a LIBOR Revolving Loan disbursed after the initial Borrowing of LIBOR
Revolving Loans shall end on the same day as the last day of the then current
Interest Period for the LIBOR Revolving Loans previously outstanding, and on the
last day of such Interest Period, the LIBOR Revolving Loans shall be
consolidated and shall thereafter have the same Interest Period.

            (c) No Interest Period for a Term Loan shall extend beyond the
Maturity Date, and no Interest Period for a Revolving Loan shall extend beyond
the Maturity Date.

            (d) If the Borrower fails to select an Interest Period for a
Borrowing of a LIBOR Loan or an outstanding LIBOR Loan under paragraph (a)
above, the Borrower shall be deemed to have selected an Interest Period of one
(1) month's duration.

            (e) The initial Interest Period with respect to the Borrowing of
Refinancing Term Loans may, at the Borrower's election, end on December 31,
2005.

            (f) Promptly following receipt of a notice from the Borrower
selecting an Interest Period, the Administrative Agent shall advise each Term
Loan Lender or the Revolving Loan Lender, as applicable, of the details thereof,
and if no timely notice is provided by the Borrower, the Administrative Agent
shall notify each Term Loan Lender or the Revolving Loan Lender, as applicable,
of the details of the applicable Interest Period.

      Section 2.5. Repayment of Loans.

            (a) Term Loans.

                  (i) The Borrower shall repay to the Administrative Agent for
      the account of the Term Loan Lenders on the Maturity Date the aggregate
      principal amount of the Term Loans outstanding on such date.

                  (ii) Principal amounts of Term Loans repaid may not be
      reborrowed.

            (b) Revolving Loans. The Borrower shall repay to the Administrative
Agent for the account of the Revolving Loan Lender on the Maturity Date the
aggregate principal amount of the Revolving Loans outstanding on such date.

      Section 2.6. Use of Proceeds of Loans.

            (a) Borrowing of Refinancing Term Loans. The proceeds of the
Borrowing of Refinancing Term Loans shall be used solely (i) to refinance
certain Indebtedness incurred by the Borrower relating to the acquisition by it
or its affiliates of certain airport service businesses; (ii) to finance a
one-time equity distribution to the Investor; (iii) to pay fees payable on the
date

                                       7

of the Borrowing of Term Loans to the Lead Arrangers and the Administrative
Agent; (iv) to make payment of the Debt Service Reserve Required Balance into
the Debt Service Reserve Account as required hereunder; (v) to pay or reimburse
the Borrower for costs and expenses payable by the Borrower pursuant hereto in
connection with the closing of the Loans; and (vi) to retain as cash on the
books of the Borrower to pay for ongoing expenditures incurred in the ordinary
course of business.

            (b) Borrowing of Trajen Acquisition Term Loans. The proceeds of the
Borrowing of Trajen Acquisition Term Loans shall be used solely (i) to finance a
portion of the acquisition costs incurred by the Investor in connection with the
Trajen Acquisition; (ii) to pay fees payable on the Trajen Acquisition Term Loan
Disbursement Date to the Lead Arranger, the Administrative Agent and the
Collateral Agent; (iii) to make payment into the Debt Service Reserve Account in
an amount which results in such account being funded with the Debt Service
Reserve Required Balance as required hereunder; and (iv) to pay or reimburse the
Borrower for costs and expenses payable by the Borrower pursuant hereto in
connection with the closing of the Trajen Acquisition Term Loans and this
Agreement.

            (c) Revolving Loans. The proceeds of the Revolving Loans shall be
used solely (i) to provide for the working capital and general corporate
purposes of the Borrower and its Subsidiaries (including capital expenditures,
maintenance and repairs); and (ii) to reimburse the Issuing Bank for Drawings.

            (d) No Monitoring Obligation. The Administrative Agent shall not be
obligated to monitor or verify the use of proceeds of the Term Loans or the
Revolving Loans.

      Section 2.7. Termination or Reduction of Commitments.

            (a) The Borrower may, upon notice to the Administrative Agent,
terminate the Commitments, or from time to time reduce the Commitments; provided
that (i) any such notice shall be received by the Administrative Agent not later
than 11:00 a.m. three (3) Business Days prior to the date of termination or
reduction, (ii) any such partial reduction shall be (A) in the case of the Term
Loans, in an aggregate amount of $1,000,000 or any whole multiple of $500,000 in
excess thereof, and (B) in the case of the Revolving Loans, in an aggregate
amount of $100,000 or any whole multiple of $50,000 in excess thereof; and (iii)
the Borrower may not reduce the Revolving Loan Commitments to an amount less
than the Letter of Credit Usage then outstanding. The Administrative Agent will
promptly notify the applicable Lenders of any such notice of termination or
reduction of any of the Commitments. Any reduction of the Term Loan Commitments
shall be made ratably among the Term Loan Lenders in accordance with their
respective Term Loan Commitments. All commitment fees accrued until the
effective date of any termination of the Commitments shall be paid on the
effective date of such termination.

            (b) If the Borrowing of the Refinancing Term Loans has not been made
on or before January 9, 2006, the Administrative Agent (acting at the direction
of the Required Lenders) may, by written notice to the Borrower, terminate the
Commitments of the Lenders with respect to each of the Loans, which termination
shall become effective immediately.

                                       8

which termination shall become effective immediately; provided that if the
Borrowing of Trajen Acquisition Term Loans in a principal amount of less than

Commitments as of such date shall be terminated.

            (d) Any termination or reduction of any of the Commitments shall be
permanent.

      Section 2.8. Prepayments.

            (a) Terms of All Prepayments. Except as otherwise provided in
Section 2.8(b) for optional prepayments and Sections 2.8(c)(v) for mandatory
prepayments required to be paid from Excess Cash Flow and as otherwise provided
in Section 3.3 for any mandatory prepayment resulting from illegality, all
partial prepayments of any of the Term Loans shall be allocated to prepay, on a
pro rata basis, the applicable Term Loans outstanding. Each prepayment of Loans
shall be accompanied by accrued interest on the amount prepaid, any additional
amounts required pursuant to Section 3.5 and any Hedging Termination Obligations
payable in connection therewith.

            (b) Optional Prepayments.

                  (i) The Borrower may at any time or from time to time
      voluntarily prepay Loans in whole or in part without premium or penalty on
      any Interest Payment Date (subject to Section 3.5(ii)); provided that the
      Borrower shall deliver notice to the Administrative Agent (or, in the case
      of prepayment of a Revolving Loan, to the Revolving Loan Lender with a
      copy thereof to the Administrative Agent) of any prepayment hereunder,
      which notice must be received by the Administrative Agent or the Revolving
      Loan Lender, as the case may be (A) not later than 11:00 a.m. five (5)
      Business Days prior to any proposed date of prepayment of Term Loans, and
      (B) not later than 11:00 a.m. three (3) Business Days prior to the
      proposed date of prepayment of Revolving Loans. Any prepayment shall (x)
      in the case of Term Loans, be in a principal amount of $1,000,000 or a
      whole multiple of $500,000 in excess thereof or, if less, the entire
      principal amount thereof then outstanding, and (y) in the case of
      Revolving Loans, be in a principal amount of $100,000 or a whole multiple
      of $50,000 in excess thereof or, if less, the entire principal amount
      thereof then outstanding. Each such notice shall be irrevocable and shall
      specify (A) the date and amount of such prepayment, (B) whether the
      prepayment is of Term Loans or Revolving Loans or a combination thereof,
      and, if a combination thereof, the amount of prepayment allocable to each,
      and (C) with respect to prepayments of Revolving Loans, the amounts to be
      applied to each Revolving Loan outstanding.

                  (ii) Promptly following receipt of any such notice of
      voluntary prepayment, the Administrative Agent shall advise the applicable
      Lenders of the contents thereof.

                                       9

<PAGE>

                  (iii) Any prepayment pursuant to this Section 2.8(b) applied
      to prepay the Revolving Loans may be reborrowed.

            (c) Mandatory Prepayments.

                  (i) If during any fiscal year of the Borrower, the aggregate
      cumulative amount of Net Asset Disposition Proceeds for such fiscal year
      exceeds $250,000, the Borrower shall, immediately after the completion of
      each sale or series of related sales or other disposition which results in
      such an excess or an increase in such an excess, (A) prepay the
      outstanding Term Loans and, if the Term Loans shall have been paid in
      full, (B) to the extent Revolving Loans are then outstanding, prepay such
      Revolving Loans (and, to the extent of any such prepayment, reduce the
      Revolving Loan Commitment), and (C) otherwise, Cash Collateralize the
      outstanding Letter of Credit Obligations, in an aggregate principal amount
      equal to one hundred percent (100%) of such excess or such increase in
      such excess. Notwithstanding the foregoing, the Borrower shall not be
      required to make a prepayment pursuant to this clause (i) with respect to
      any sale or series of related sales (a "RELEVANT SALE") if the Borrower
      advises the Administrative Agent in writing at the time the Net Asset
      Disposition Proceeds from such Relevant Sale are received that it intends
      to reinvest all or any portion of such Net Asset Disposition Proceeds in
      replacement assets to the extent (A) such Net Asset Disposition Proceeds
      are in fact committed to be reinvested by the Borrower pursuant to a
      purchase contract providing for the acquisition of such replacement assets
      that is executed by the Borrower and the related seller within 45 days
      from the date of such Relevant Sale and (B) the acquisition of such
      replacement assets occurs within 180 days from the date on which such
      purchase contract is so executed and delivered. If, at any time after the
      occurrence of a Relevant Sale and prior to the acquisition of the related
      replacement assets, the 45 or 180 day period provided in clause (A) or (B)
      of the preceding sentence shall elapse without execution of the related
      purchase contract (in the case of clause (A)) or the occurrence of the
      related acquisition (in the case of clause (B)) or an Event of Default
      shall have occurred and be continuing, then the Borrower shall immediately
      prepay the Loans in the amount and in the manner described in the first
      sentence of this clause (i).

                  (ii) If, at any time after the Closing Date, the Borrower or
      any of its Subsidiaries issues or incurs any Indebtedness for borrowed
      money, including Indebtedness evidenced by notes, bonds, debentures or
      other similar instruments, but excluding Permitted Indebtedness, the
      Borrower shall, immediately after such issuance or incurrence, (A) prepay
      the outstanding Term Loans and, if the Term Loans shall have been paid in
      full, (B) to the extent Revolving Loans are then outstanding, prepay such
      Revolving Loans (and, to the extent of any such prepayment, reduce the
      Revolving Loan Commitment), and (C) otherwise, Cash Collateralize the
      outstanding Letter of Credit Obligations, in an aggregate principal amount
      equal to one hundred percent (100%) of the Net Debt Proceeds of such
      Indebtedness.

                  (iii) If, at any time after the Closing Date, the Borrower or
      any of its Subsidiaries issues or sells any Equity Securities (other than
      any issuance or sale specified in the proviso to the definition of Net
      Equity Proceeds or in connection with the

                                       10

<PAGE>

      funding of Expansion Capital Expenditures or the prepayment of Loans
      pursuant to Section 2.8(c)(vi)), the Borrower shall, immediately after
      such issuance or sale, (A) prepay the outstanding Term Loans and, if the
      Term Loans shall have been paid in full, (B) to the extent Revolving Loans
      are then outstanding, prepay such Revolving Loans (and, to the extent of
      any such prepayment, reduce the Revolving Loan Commitment), and (C)
      otherwise, Cash Collateralize the outstanding Letter of Credit
      Obligations, in an aggregate principal amount equal to one hundred percent
      (100%) of the Net Equity Proceeds of such Equity Securities.

                  (iv) No later than three (3) Business Days following (x) the
      date of receipt by the Borrower or any of its Subsidiaries of any Net
      Insurance Proceeds (other than insurance proceeds in respect of business
      interruption or anticipated loss in revenue) or Net Condemnation Proceeds,
      or (y) if applicable, the end of the 180-day period described in the
      proviso below), the Borrower shall (A) prepay the outstanding Term Loans
      and, if the Term Loans shall have been paid in full, (B) to the extent
      Revolving Loans are then outstanding, prepay such Revolving Loans (and, to
      the extent of any such prepayment, reduce the Revolving Loan Commitment),
      and (C) otherwise, Cash Collateralize the outstanding Letter of Credit
      Obligations, in an amount equal to the aggregate amount of the sum of such
      Net Insurance Proceeds and Net Condemnation Proceeds in such fiscal year
      (excluding any amounts used to repair, restore or replace assets in
      accordance with the immediately following proviso); provided that the
      Borrower shall not be obligated to make a prepayment under this clause
      (iv) if and to the extent that (i) the Borrower advises the Administrative
      Agent in writing at the time the applicable Loan Party receives such
      proceeds that such Loan Party intends to repair, restore or replace the
      assets from which such Net Insurance Proceeds or Net Condemnation Proceeds
      derived, and does so within 180 days of receipt thereof (or such longer
      period as is reasonably required to complete such repair, restoration or
      replacement; provided that the applicable Loan Party shall have commenced
      such repair, restoration or replacement during such 180-day period and
      thereafter proceeds with all due diligence to complete such repair,
      restoration or replacement within a reasonable period of time acceptable
      to the Administrative Agent), it being understood that any Net Insurance
      Proceeds or Net Condemnation Proceeds retained by such Loan Party but not
      actually expended within such time period to repair, restore or replace
      the assets from which such Net Insurance Proceeds or Net Condemnation
      Proceeds derived shall at that time immediately be used to prepay the
      Loans in the amount and in the manner described in the first sentence of
      this clause (iv).

                  (v) If, following a deposit of Excess Cash Flow to the Special
      Reserve Account pursuant to Section 6.1(q)(iii)(B), one or more of the
      conditions to Distribution set forth in Section 6.2(f)(i)(B) (the
      "DISTRIBUTION REQUIREMENTS") are not satisfied as of each of the
      succeeding two (2) consecutive Calculation Dates, all monies that have
      been on deposit in the Special Reserve Account for a period of two (2)
      consecutive fiscal quarters or longer shall be applied to prepay the
      Loans. All prepayments of the Loans then outstanding pursuant to this
      clause (v) shall be applied (A) to prepay the outstanding Term Loans and,
      if the Term Loans shall have been paid in full, (B) to the extent
      Revolving Loans are then outstanding, prepay such Revolving Loans (and, to
      the extent of any such prepayment, reduce the Revolving Loan

                                       11

<PAGE>

      Commitment), and (C) otherwise, to Cash Collateralize the outstanding
      Letter of Credit Obligation. All funds on deposit in the Special Reserve
      Account (other than any monies required to prepay Loans in accordance with
      Section 2.8(c)(v) or 2.8(c)(vi)) shall be released to the Borrower or at
      the Borrower's direction as Cash Available for Distribution if the
      Distribution Requirements are satisfied for each of such two (2)
      consecutive Calculation Dates, and the Borrower may make a Distribution of
      such funds.

                  (vi) If, during the Leverage Ratio Test Period, any Applicable
      Leverage Ratio is not achieved, the Borrower shall (within two (2)
      Business Days after the Borrower have delivered a certified calculation of
      the Leverage Ratio for the applicable quarterly period pursuant to Section
      6.1(a)(vii)), prepay the Loans from Excess Cash Flow, or from equity
      contributions by the Investor, in such amounts as are required to achieve
      such Applicable Leverage Ratio. All prepayments of the Loans then
      outstanding pursuant to this clause (vi) shall be applied (A) to prepay
      the outstanding Term Loans and, if the Term Loans shall have been paid in
      full, (B) to the extent Revolving Loans are then outstanding, prepay such
      Revolving Loans (and, to the extent of any such prepayment, reduce the
      Revolving Loan Commitment), and (C) otherwise, to Cash Collateralize the
      outstanding Letter of Credit Obligation.

                  (vii) The proceeds of any termination payment or similar
      compensation received by any Subsidiary of the Borrower from an Airport
      Authority or any other party in respect of the termination of any FBO
      Lease, Management Contract or the Heliport Contract shall be applied,
      immediately upon receipt of such payment, (A) to prepay the outstanding
      Term Loans and, if the Term Loans shall have been paid in full, (B) to the
      extent Revolving Loans are then outstanding, prepay such Revolving Loans
      (and, to the extent of any such prepayment, reduce the Revolving Loan
      Commitment), and (C) otherwise, to Cash Collateralize the outstanding
      Letter of Credit Obligation; provided that no such prepayment shall be
      required if the Borrower makes a prepayment that cures an Event of Default
      relating to such Material Contract or Subsidiary as permitted by the last
      paragraph of Section 7.1.

      Section 2.9. Fees.

            (a) Commitment Fees. The Borrower agrees to pay (i) to the
Administrative Agent for the account of each applicable Term Loan Lender a
commitment fee equal to 0.50% per annum on the daily amount of the Available
Refinancing Term Loan Commitment of such Term Loan Lender during the period from
and including the "Closing Date" under, and as defined in, the Original Loan
Agreement to but excluding the last day of the Refinancing Term Loan Commitment
Period, (ii) to the Administrative Agent for the account of each applicable Term
Loan Lender a commitment fee equal to 0.50% per annum on the daily amount of the
Available Trajen Acquisition Term Loan Commitment of such Term Loan Lender
during the period from and including the Closing Date to but excluding the last
day of the Trajen Acquisition Term Loan Commitment Period, and (iii) to the
Revolving Loan Lender for its own account a commitment fee equal to 0.50% per
annum on the daily amount of the Available Revolving Loan Commitment during the
period from and including the Closing Date to but excluding the last day of the
Revolving Loan Commitment Period. Accrued commitment fees shall be payable in
arrears on the last Business Day of March, June, September and December of

                                       12

<PAGE>

each year, commencing on the first of such dates to occur after the Closing Date
(as defined in the Original Loan Agreement and this Agreement, as applicable)
and on the last day of the applicable Commitment Period. All commitment fees
shall be calculated on the basis of a year of 360 days and for the actual days
elapsed (including the first day but excluding the last day).

            (b) Letter of Credit Fees. The Borrower shall pay to the Revolving
Loan Lender a letter of credit fee for each Letter of Credit issued pursuant to
Section 2.13 at a rate per annum equal to the Applicable Margin for LIBOR
Revolving Loans multiplied by the daily maximum amount available to be drawn
under such Letter of Credit, calculated on the basis of a year of 360 days and
for the actual days elapsed (including the first day but excluding the last
day), for the period from date of issuance of such Letter of Credit until the
expiry or termination thereof. Such fee shall be payable in arrears on the last
Business Day of March, June, September and December of each year, commencing on
the first of such dates to occur after the issuance of a Letter of Credit
pursuant to Section 2.13, and on the Letter of Credit Expiration Date.

            (c) Documentary And Processing Charges Payable To Issuing Bank. The
Borrower shall pay directly to the Issuing Bank for its own account the
customary and reasonable issuance, presentation, amendment, negotiation and
other processing fees, and other standard and reasonable costs and charges, of
the Issuing Bank relating to letters of credit as from time to time in effect.
Such fees and charges are due and payable on demand and once paid, are
nonrefundable.

            (d) Other Fees. The Borrower agrees to pay to the Lead Arrangers,
the Administrative Agent and the Issuing Bank for their own respective accounts
fees payable in the amounts and at the times separately agreed upon between the
Borrower and such parties, which fees shall be deemed to be payable hereunder.

            (e) Fees Fully Earned When Paid. All fees shall be fully earned when
paid and shall not be refundable under any circumstances.

      Section 2.10. Evidence of Indebtedness; Notes.

      The Loans made by each Lender shall be evidenced by one or more accounts
or records maintained by such Lender and by the Administrative Agent in the
ordinary course of business. The accounts or records maintained by the
Administrative Agent and each Lender shall be conclusive absent manifest error
of the amount of the Loans made by the Lenders to the Borrower and the interest
and payments thereon. Any failure to so record or any error in doing so shall
not, however, limit or otherwise affect the obligation of the Borrower hereunder
to pay any amount owing with respect to the Obligations. In the event of any
conflict between the accounts and records maintained by any Lender and the
accounts and records of the Administrative Agent in respect of such matters, the
accounts and records of the Administrative Agent shall control in the absence of
manifest error. Upon the request of any Lender made through the Administrative
Agent, the Borrower shall execute and deliver to such Lender (through the
Administrative Agent) a Note, which shall evidence such Lender's Loans in
addition to such accounts or records. Each Lender may attach schedules to its
Note and endorse thereon the date, amount and maturity of its Loans and payments
with respect thereto.

                                       13

<PAGE>

      Section 2.11. Payments Generally.

            (a) Each payment by the Borrower hereunder (whether of principal,
interest, fees or any other amount) shall be made prior to 12:00 noon, New York
City time, on the date when due, in Dollars in immediately available funds,
without condition or deduction for any counterclaim, defense, recoupment or
setoff. Any amounts received after such time on any date may, in the discretion
of the Administrative Agent or, with respect to Revolving Loans, the Revolving
Loan Lender, be deemed to have been received on the next succeeding Business Day
for purposes of calculating interest thereon. All payments shall be made to the
account of the Administrative Agent (account number H79-740-222205) at Mizuho
Corporate Bank, Ltd. (ABA number 026-004-307) or such other account as may
hereafter be designated by the Administrative Agent in writing. The
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly upon receipt
thereof, in like funds as received.

            (b) If any payment to be made by the Borrower under any Loan
Document becomes due and payable on a day other than a Business Day, the date
for payment shall be extended to the next succeeding Business Day, and such
extension of time shall be reflected in computing interest or fees.

            (c) If at any time insufficient funds are received by and available
to the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied (i) first, towards payment
of interest and fees then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of interest and fees then due to such
parties, and (ii) second, towards payment of principal then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal then due to such parties.

      Section 2.12. Sharing of Payments.

      If any Lender shall, by exercising any right of set-off or counterclaim or
otherwise, obtain payment in respect of any principal of or interest on its Term
Loans or Revolving Loans or participation in the Letter of Credit Facility,
resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of such Loans or such participation in the Letter of Credit
Facility and accrued interest thereon than the proportion received by any other
Lender, then the Lender receiving such greater proportion shall purchase (for
cash at face value) participations in the Term Loans, Revolving Loans and
participations in the Letter of Credit Facility of the other Lenders to the
extent necessary so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Term Loans, Revolving Loans and
participations in the Letter of Credit Facility; provided that (i) if any such
participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase
price restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to the Borrower or Affiliate thereof (as to which the
provisions

                                       14

<PAGE>

of this paragraph shall apply). The Borrower consents to the foregoing and
agrees, to the extent it may effectively do so under applicable Legal
Requirement, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against the Borrower all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were a direct creditor of the Borrower in the amount of such
participation.

      Section 2.13. Letter of Credit Facility.

            (a) Letter of Credit Commitment. Subject to the terms and conditions
set forth herein, the Issuing Bank agrees to issue standby Letters of Credit
under the Letter of Credit Facility for the account of the Borrower from time to
time prior to the Letter of Credit Expiration Date or, at any time when the
Revolving Loan facility is in effect, during the Revolving Loan Commitment
Period; provided that (i) no Letter of Credit pursuant to this Section 2.13
shall be issued prior to the Borrowing of the Term Loans (except as provided in
the last sentence of this clause (a)), (ii) the face amount of any such
requested Letter of Credit shall not, at the time of issuance, exceed the
Revolving Loan Commitment at any time when the Revolving Loan facility is in
effect; (iii) the aggregate outstanding Letter of Credit Usage shall not exceed
the Letter of Credit Sublimit at any time; and (iv) each such Letter of Credit
shall have an expiration date that is no later than the date that is one (1)
year from the date of issue, unless as otherwise agreed to by the Issuing Bank;
provided that no such Letter of Credit shall have an expiration date later than
the Letter of Credit Expiration Date. The obligation of the Issuing Bank to
issue Letters of Credit shall expire on the Letter of Credit Expiration Date or,
if the Revolving Loan facility is in effect, the last day of the Revolving Loan
Commitment Period. Each Letter of Credit pursuant to this Section 2.13 shall be
in a form reasonably acceptable to the Issuing Bank.

            (b) Procedure For Issuance of Letter of Credit. To request the
issuance of a Letter of Credit (or the amendment, renewal or extension of an
outstanding Letter of Credit) pursuant to this Section 2.13, the Borrower shall
deliver to the Issuing Bank (with a copy thereof to the Administrative Agent)
(which request must be received by the Issuing Bank and the Administrative Agent
not later than 11:00 a.m., New York City time, three (3) Business Days before
the requested date of issuance, amendment, renewal or extension) an irrevocable
written request for the issuance of a Letter of Credit, or identifying the
Letter of Credit to be amended, renewed or extended, and specifying the date of
issuance, amendment, renewal or extension (which shall be a Business Day), the
date on which such Letter of Credit is to expire (which shall comply with
paragraph (a) of this Section 2.13), the amount of such Letter of Credit, the
name and address of the beneficiary thereof and such other information as shall
be necessary to prepare, amend, renew or extend such Letter of Credit. If
requested by the Issuing Bank, the Borrower also shall submit a letter of credit
application on the Issuing Bank's standard form in connection with any request
for a Letter of Credit.

            (c) Revolving Loan Lender Participation. Immediately upon the
issuance of a Letter of Credit in accordance with this Section 2.13, the Issuing
Bank shall be deemed to have sold and transferred to the Revolving Loan Lender,
and the Revolving Loan Lender shall be deemed to have purchased and received
from the Issuing Bank, in each case irrevocably and without any further action
by any party, an undivided interest and participation in such Letter of Credit,
each Drawing and other Reimbursement Obligations of the Borrower in respect
thereof in an amount equal to the applicable Outstanding Amount then in effect.
The Issuing Bank shall

                                       15

<PAGE>

promptly advise the Revolving Loan Lender of the changes in the applicable
Outstanding Amount or Letter of Credit Expiration Date and any Drawing
therefrom; provided that the failure to give such notice shall not limit or
impair the rights of the Issuing Bank hereunder and under the Loan Documents.

            (d) Payment of Drawing. Upon a Drawing, the Borrower shall be
obligated to pay to the Issuing Bank a Reimbursement Obligation in the amount of
the Drawing not later than 12:00 noon, New York City time, on the same Business
Day that the Drawing is made, if the Borrower shall have received notice of such
Drawing prior to 10:00 a.m., New York City time, on such date, or, if such
notice was received by the Borrower after such time, then not later than 12:00
noon, New York City time on the immediately following Business Day unless the
reimbursement is made by a Revolving Loan (and in the latter case such payment
shall include interest on the Reimbursement Obligation from the date of the
Drawing to such payment date). Unless the Borrower shall notify the Issuing
Bank, the Revolving Loan Lender and the Administrative Agent that such
Reimbursement Obligation will be paid by the Borrower without using a Revolving
Loan, the payment by the Issuing Bank of such Drawing shall be deemed
automatically to be a request for the making by the Revolving Loan Lender of a
Revolving Loan to the Borrower in the amount of such Drawing on the date of such
Drawing, and the Issuing Bank shall promptly so notify the Revolving Loan
Lender. The Revolving Loan Lender shall, on the Business Day of the Drawing,
make a Revolving Loan for the account of the Borrower in an amount equal to the
Drawing, the proceeds of which shall be applied to reimburse the Issuing Bank.
The obligation of the Revolving Loan Lender to so reimburse the Issuing Bank by
making a Revolving Loan shall be absolute and unconditional and shall not be
affected by the occurrence of an Event of Default or any other occurrence or
event. In the event that the Revolving Loan Lender fails to make available for
the account of the Issuing Bank the amount of such Revolving Loan, the Issuing
Bank shall be entitled to recover such amount on demand from such Lender
together with interest thereon at a rate equal to the daily average Federal
Funds Rate.

            (e) Conditions To Issuance of Letters of Credit. The obligation of
the Issuing Bank to issue any Letter of Credit pursuant to this Section 2.13 is
subject to the satisfaction, on the proposed issuance date, of the following
conditions precedent: (i) all representations and warranties of each Loan Party
contained in the Loan Documents shall be true, correct and accurate in all
respects on and as of such issuance date (except to the extent such
representations and warranties relate to an earlier date), and (ii) no Default
or Event of Default shall have occurred or be continuing.

            (f) Replacement of The Issuing Bank. The Issuing Bank may be
replaced at any time by written agreement among the Borrower, the Administrative
Agent, the Revolving Loan Lender, the replaced Issuing Bank and the successor
Issuing Bank, and upon replacement of any outstanding Letters of Credit with
replacements issued by the successor Issuing Bank; provided that any successor
Issuing Bank shall have a credit rating for its Reference Debt that is
reasonably acceptable to the beneficiaries of the replacement Letters of Credit.
The Administrative Agent shall notify the Lenders of any such replacement of the
Issuing Bank. At the time any such replacement shall become effective, the
Borrower shall pay all unpaid fees accrued for the account of the replaced
Issuing Bank pursuant to Section 2.9. From and after the effective date of any
such replacement, (i) the successor Issuing Bank shall have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Letters of
Credit to be

                                       16

<PAGE>

issued thereafter and (ii) references herein to the term "Issuing Bank" shall be
deemed to refer to such successor or to any previous Issuing Bank, or to such
successor and all previous Issuing Banks, as the context shall require.

                                   ARTICLE III

                           TAXES AND YIELD PROTECTION

      Section 3.1. Taxes.

            (a) Any and all payments by or on account of any obligation of the
Borrower hereunder or under any other Loan Document shall be made free and clear
of and without deduction for any Indemnified Taxes or Other Taxes; provided that
if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes
from such payments, then (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 3.1) the Administrative Agent or
Lender (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable Legal
Requirements.

            (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable Legal
Requirements.

            (c) The Borrower shall indemnify the Administrative Agent and each
Lender, within ten (10) days after written demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender, as the case may be, on or with respect to any payment by or on account
of any obligation of the Borrower hereunder or under any other Loan Document
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 3.1) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to
the amount of such payment or liability delivered to the Borrower by a Lender or
by the Administrative Agent on its own behalf or on behalf of a Lender shall be
conclusive absent manifest error.

            (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority in accordance with
clause (a) or (b) above, the Borrower shall deliver to the Administrative Agent
the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of the return reporting such payment
or other evidence of such payment reasonably satisfactory to the Administrative
Agent.

            (e) Each Foreign Lender shall deliver to the Administrative Agent,
prior to receipt of any payment subject to withholding under the IRC (or upon
accepting an assignment of an interest herein), two duly signed completed copies
of either IRS Form W-8BEN or any successor thereto (relating to such Foreign
Lender and entitling it to an exemption from, or

                                       17

<PAGE>

reduction of, withholding tax on all payments to be made to such Foreign Lender
by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor
thereto (relating to all payments to be made to such Foreign Lender by the
Borrower pursuant to this Agreement) or such other evidence satisfactory to the
Borrower and the Administrative Agent that such Foreign Lender is entitled to an
exemption from, or reduction of, U.S. withholding tax, including any exemption
pursuant to Section 881(c) of the IRC. Thereafter and from time to time, each
such Foreign Lender shall (A) promptly submit to the Administrative Agent such
additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Borrower and the Administrative Agent of any available exemption from or
reduction of, United States withholding taxes in respect of all payments to be
made to such Foreign Lender by the Borrower pursuant to this Agreement, and (B)
promptly notify the Administrative Agent of any change in circumstances which
would modify or render invalid any claimed exemption or reduction.

            (f) If any Governmental Authority asserts that the Administrative
Agent did not properly withhold or backup withhold, as the case may be, any tax
or other amount from payments made to or for the account of any Lender, such
Lender shall indemnify the Administrative Agent therefor, including all
penalties and interest, any taxes imposed by any jurisdiction on the amounts
payable to the Administrative Agent under this Section 3.1, and costs and
expenses of the Administrative Agent. The obligation of the Lenders under this
Section 3.1 shall survive the termination of the Commitments, repayment of all
other Obligations hereunder and the resignation of the Administrative Agent.

            (g) If a Lender assigns a Loan to a United States Person that is not
an "exempt recipient" as defined in Treasury Regulation Section
1.6049-4(c)(1)(ii), such assignee shall provide two duly signed and completed
copies of IRS form W-9 (or any successor form thereto) to the Administrative
Agent.

      Section 3.2. Alternate Rate of Interest.

      If prior to the commencement of any Interest Period or the borrowing of
any LIBOR Revolving Loan, (a) the Administrative Agent or the Revolving Loan
Lender, as applicable, determines (which determination shall be conclusive
absent manifest error) that adequate and reasonable means do not exist for
ascertaining LIBOR for such Interest Period or (b) the Administrative Agent is
advised by the Required Lenders, or, in the case of LIBOR Revolving Loans, the
Revolving Loan Lender, determines, that LIBOR determined or to be determined for
such Interest Period will not adequately and fairly reflect the cost to such
Lenders or Revolving Loan Lender, as applicable, of making or maintaining such
Loans for such Interest Period, the Administrative Agent or the Revolving Loan
Lender, as applicable, shall promptly give notice thereof to the Borrower and,
if applicable, the Required Lenders, by telephone or telecopy as promptly as
practicable thereafter and, until the Administrative Agent or the Revolving Loan
Lender, as applicable, notifies the Borrower and, if applicable, such Required
Lenders, that the circumstances giving rise to such notice no longer exist, the
Administrative Agent or the Revolving Loan Lender, as applicable, shall promptly
give written notice thereof to the Borrower and, if applicable, such Required
Lenders. If such notice is given with respect to Term Loans,

                                       18

<PAGE>

the rate of interest on each applicable Lender's Loans for each Interest Period
thereafter will be the average cost of funds for the Required Lenders, as
reasonably determined by the Administrative Agent, plus the Applicable Margin.
If such notice is given with respect to Revolving Loans, all LIBOR Revolving
Loans shall be deemed to have been converted into Base Rate Revolving Loans
effective upon the giving of such notice, and LIBOR Revolving Loans shall
thereafter not be available until the Revolving Loan Lender advises the Borrower
that the circumstances giving rise to such notice no longer exist.

      Section 3.3. Illegality.

      If any Lender determines that any Legal Requirement has made it unlawful,
or that any Governmental Authority has asserted that it is unlawful, for any
Lender or its applicable Lending Office to make, maintain or fund LIBOR Loans,
or to determine or charge interest rates based upon LIBOR, then, on notice
thereof by such Lender to the Borrower (through the Administrative Agent, in the
case of any Term Loans), any obligation of such Lender to make or continue LIBOR
Loans or to convert Base Rate Revolving Loans to LIBOR Revolving Loans shall be
suspended until such Lender notifies the Administrative Agent and the Borrower
that the circumstances giving rise to such determination no longer exist. Upon
receipt of such notice, the Borrower shall, upon demand from such Lender (with a
copy to the Administrative Agent), prepay, either on the last day of the
Interest Period therefor, if such Lender may lawfully continue to maintain such
LIBOR Loans to such day, or immediately, if such Lender is the Revolving Loan
Lender and/or such Lender may not lawfully continue to maintain such LIBOR
Loans; provided that (i) in the case of Term Loans, if prior to such prepayment
date the affected Lender and the Borrower can agree upon an alternative mutually
acceptable basis for determining the interest rate from time to time applicable
to the Term Loans owing to such Lender that will avoid such illegality (it being
understood and agreed that the Base Rate shall be an acceptable substitute rate
if the Borrower so elects and it shall be legal for such Lender to maintain its
Loans as Base Rate Loans), such interest rate shall take effect from the date of
such agreement and lieu of such required prepayment; and (ii) in the case of
LIBOR Revolving Loans, if conversion of such Revolving Loans into Base Rate
Loans will avoid such illegality, all LIBOR Revolving Loans shall be converted
to Base Rate Revolving Loans. Upon any such prepayment or conversion, the
Borrower shall also pay accrued interest on the amount so prepaid or converted.

      Section 3.4. Increased Costs.

            (a) If any Change in Law shall:

                  (i) impose, modify or deem applicable any reserve, special
      deposit or similar requirement against assets of, deposits with or for the
      account of, or credit extended by, any Lender or the Issuing Bank
      (including any reserve established by the Federal Reserve Board); or

                  (ii) impose on any Lender or the Issuing Bank or the London
      interbank market any other condition affecting this Agreement or Loans
      made by such Lender or any Letter of Credit issued by the Issuing Bank
      pursuant to Section 2.13;

                                       19

<PAGE>

and the result of any of the foregoing shall be to increase the cost to such
Lender or the Issuing Bank of making or maintaining any Loan or such Letter of
Credit (or of maintaining its obligation to make any such Loan or Letter of
Credit) or to reduce the amount of any sum received or receivable by such Lender
or the Issuing Bank hereunder (whether of principal, interest or otherwise),
then the Borrower will pay to such Lender or the Issuing Bank, as applicable,
such additional amount or amounts as will compensate such Lender or the Issuing
Bank, as applicable, for such additional costs incurred or reduction suffered.

            (b) If any Lender or the Issuing Bank determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's or the Issuing Bank's capital or on the capital
of such Lender's or the Issuing Bank's holding company, if any, as a consequence
of this Agreement or the Loans made by such Lender or the Letters of Credit
issued by the Issuing Bank, to a level below that which such Lender or the
Issuing Bank or such Lender's or the Issuing Bank's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's or
the Issuing Bank's policies and the policies of such Lender's or the Issuing
Bank's holding company with respect to capital adequacy), then from time to time
the Borrower will pay to such Lender or the Issuing Bank, as applicable, such
additional amount or amounts as will compensate such Lender or the Issuing Bank
or such Lender's or the Issuing Bank's holding company for any such reduction
suffered.

            (c) A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its
holding company, as the case may be, as specified in paragraph (a) or (b) of
this Section 3.4 shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender or the Issuing Bank,
as applicable, the amount shown as due on any such certificate within ten (10)
days after receipt thereof.

            (d) Failure or delay on the part of any Lender or the Issuing Bank
to demand compensation pursuant to this Section 3.4 shall not constitute a
waiver of such Lender's or the Issuing Bank's right to demand such compensation;
provided that the Borrower shall not be required to compensate a Lender or the
Issuing Bank pursuant to this Section 3.4 for any increased costs or reductions
incurred more than 180 days prior to the date that such Lender or the Issuing
Bank, as the case may be, notifies the Borrower of the Change in Law giving rise
to such increased costs or reductions and of such Lender's or the Issuing Bank's
intention to claim compensation therefor; and provided, further, that if the
Change in Law giving rise to such increased costs or reductions is retroactive,
then the 180-day period referred to above shall be extended to include the
period of retroactive effect thereof.

      Section 3.5. Funding Losses.

      The Borrower agrees to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur as a
consequence of (i) any failure by the Borrower (for a reason other than the
wrongful failure of such Lender to make a Loan) to borrow or prepay any Loan on
the date or in the amount notified by the Borrower, or (ii) any payment or
prepayment of any Loan on a day other than the last day of an Interest Period
with respect thereto (whether voluntary, mandatory, by reason of acceleration,
or otherwise),

                                       20

<PAGE>

including the amount (if any) determined by the relevant Lender by which (x) the
interest at the LIBOR which such Lender would have received for the period from
the date of receipt of funds to repay or prepay a Loan to the last day of the
applicable Interest Period for such Loan if the principal received had been paid
on the last day of such Interest Period exceeds (y) the amount which such Lender
would be able to obtain by placing an amount equal to the amount received by it
on deposit with a leading bank in the appropriate interbank market for a period
starting on the Business Day following receipt and ending on the last day of the
applicable Interest Period. Any Lender demanding indemnification for any loss or
expense sustained or incurred by it pursuant to this Section 3.5 shall, at the
time of such demand, deliver to the Borrower a certificate specifying in
reasonable detail the additional amount to be paid to it for any such loss or
expense. Each determination by a Lender of the amounts owing to it pursuant to
this Section 3.5 shall be conclusive and binding in the absence of manifest
error.

      Section 3.6. Duty to Mitigate; Replacement of Lenders.

            (a) If the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.1, or if any Lender requests compensation under Section 3.4, or if the
Borrower would be required to prepay the Loans of any Lender pursuant to Section
3.3, then such Lender shall use reasonable efforts to designate a different
lending office for funding or booking its Loans hereunder or to assign its
rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Lender, such designation or assignment
(i) would eliminate or reduce amounts payable pursuant to Section 3.1 or 3.4 or
avoid the prepayment under Section 3.3), as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would
not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to
pay all reasonable costs and expenses incurred by any Lender in connection with
any such designation or assignment.

            (b) If the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.1, or if any Lender requests compensation under Section 3.4, or if the
Borrower would be required to prepay the Loans of any Lender pursuant to Section
3.3, or if any Lender defaults in its obligation to fund Loans hereunder, then
the Borrower may, at its sole expense and effort, upon notice to such Lender and
the Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 10.4), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrower (in the case of all other amounts) and (iii)
in the case of any such assignment resulting from payments required to be made
pursuant to Section 3.1 or a claim for compensation under Section 3.4, such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender

                                       21

<PAGE>

or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

      Section 3.7. Survival.

      All of the Borrower's obligations under this Article III shall survive
termination of the Commitments and the payment in full of all Obligations.

      Section 5.12. No Agreements to Sell Assets; Etc.

Benefit Plan is a Plan. Except as set forth on Schedule 5.13, as of the Closing
Date, neither the Borrower nor any of its Subsidiaries have (i) any liability
with respect to any post-retirement benefit under any Employee Benefit Plan
which is an employee welfare benefit plan (as defined in section 3(1) of ERISA),
other than liability for health plan continuation coverage described in Part 6
of Title I of ERISA, or (ii) any liability which is reasonably expected to have
a Material Adverse Effect.

            (b) Except for compliance failures which may be corrected under the
Employee Plans Compliance Resolution System without a Material Adverse Effect,
each Employee Benefit Plan complies, in both form and operation, in all material
respects, with its terms, ERISA and the IRC, and, to the knowledge of the
Borrower, no condition exists or event has occurred with respect to any such
plan which would result in the incurrence by the Borrower or any of its
Subsidiaries or any ERISA Affiliate of any liability, fine or penalty which
would result in a Material Adverse Effect. Each Employee Benefit Plan, related
trust agreement, arrangement and commitment of the Borrower or any of its
Subsidiaries or any ERISA Affiliate is legally valid and binding and in full
force and effect, except to the extent that the failure to be so legally valid,
binding, and in full force and effect could not reasonably be expected to have a
Material Adverse Effect. To the best knowledge of the Borrower or any other Loan
Party, as of the Closing Date no Employee Benefit Plan is being audited or
investigated by any government agency or is subject to any pending or threatened
material claim or suit, other than claims for benefits in the ordinary course.

Borrower, the ERISA Affiliates or any fiduciary of any Employee Benefit Plan
has, individually or in the aggregate, engaged in a prohibited transaction under
section 406 of ERISA or section 4975 of the IRC which would result in a Material
Adverse Effect to the Loan Parties, taken as a whole.

            (c) Except as set forth on Schedule 5.13, none of the Borrower or
any of its Subsidiaries or the ERISA Affiliates contributes to or has any
material contingent obligations to any Multiemployer Plan. None of the Borrower
or any of its Subsidiaries or the ERISA Affiliates has any material liability
(including secondary liability) to any Multiemployer Plan as a result of a
complete or partial withdrawal from such Multiemployer Plan under section 4201
of ERISA or as a result of a sale of assets described in section 4204 of ERISA,
which liability could reasonably be expected to have a Material Adverse Effect.
None of the Borrower or any of its Subsidiaries or the ERISA Affiliates has been
notified that any Multiemployer Plan is in reorganization or insolvent under and
within the meaning of section 4241 or section 4245 of ERISA or that any
Multiemployer Plan intends to terminate or has been terminated under section
4041A of ERISA, except to the extent that such event could not reasonably be
expected to have a Material Adverse Effect.

copyrights owned by any such Loan Party which is registered with any
Governmental Authority is set forth on Schedule 5.15. The Borrower and its
Subsidiaries conduct their respective businesses without infringement or, to the
best of the Borrower's knowledge, claim of infringement of any trademark, trade
name, trade secret, service mark, patent, copyright, license or other
intellectual property right of other Persons, except where such infringement or
claim of infringement could not reasonably be expected to have a Material
Adverse Effect. There is no infringement or, to the best of the Borrower's
knowledge, claim of infringement by others of any material trademark, trade
name, trade secret, service mark, patent, copyright, license or other
intellectual property right of any of such Loan Parties.

      Section 5.16. Governmental Charges.

directly or indirectly, any Margin Stock or to

                                       42

extend credit, directly or indirectly, to any Person for the purpose of

                  (ix) as soon as possible and in no event later than five (5)

continuing, no such notice is required), to visit and inspect any of the
properties and offices of the Borrower or its Subsidiaries, to conduct audits of
any or

                                       50

<PAGE>

all of the Collateral, to examine the books and records of the Borrower or its
Subsidiaries and make copies thereof, and to discuss the affairs, finances and
business of the Borrower or its Subsidiaries with, and to be advised as to the
same by, their officers, auditors and accountants, all at such times and
intervals as the Administrative Agent or any Lender may reasonably request. The
Borrower may have a representative attend any meeting with the Borrower's
independent accountants so long as such right does not unreasonably delay the
scheduling of any meeting. Inspections pursuant to this Section 6.1(d) shall be
at the Borrower's expense with respect to one (1) inspection in any calendar
year and with respect to all inspections and audits during the existence of a
Default or Event of Default.

            (e) Insurance. The Borrower shall cause its Subsidiaries to do the
following:

                  (i) carry and maintain insurance during the term of this
      Agreement of the types, in the amounts and subject to such deductibles and
      other terms customarily carried from time to time by others engaged in
      substantially the same business as such Person and operating in the same
      geographic area as such Person, including, but not limited to, fire,
      public liability, property damage and worker's compensation;

                  (ii) without limiting the foregoing, carry and maintain
      insurance during the term of this Agreement of the types, in no lower
      amounts and subject to no higher deductibles as are carried by the
      Borrower and its Subsidiaries as of the Closing Date unless the
      Administrative Agent shall have otherwise consented in writing (which
      consent shall not be unreasonably withheld); provided that the Borrower
      shall be permitted to consolidate the insurance policies carried by Trajen
      and its Subsidiaries with the insurance policies currently carried by the
      Borrower without violating this clause (ii); and provided, further, that
      promptly following such consolidation, the Borrower shall submit to the
      Administrative Agent an updated summary of all insurance coverage showing
      changes to the insurance policies resulting from such consolidation, as
      certified by a Responsible Officer of the Borrower, which summary must be
      reasonably satisfactory to the Administrative Agent.

                  (iii) furnish to the Administrative Agent, upon written
      request, certificates of insurance in a form reasonably acceptable to the
      Administrative Agent as to the insurance carried;

                  (iv) carry and maintain each policy for such insurance with
      (A) a company which is rated A- or better by A.M. Best and Company, with
      unimpaired policyholders' surplus of $50 million or more, at the time such
      policy is placed and at the time of each annual renewal thereof or (B) any
      other insurer which is reasonably satisfactory to the Administrative
      Agent; and

                  (v) obtain and maintain endorsements reasonably acceptable to
      the Administrative Agent for such insurance naming the Administrative
      Agent and the Collateral Agent as additional insured and (with respect to
      those insurance policies in which the naming of a first loss payee is
      market standard in the insurance industry with respect to airport services
      businesses) the Collateral Agent as first loss payee; provided that, at
      any time the Collateral Agent receives proceeds of any such insurance as
      first loss

                                       51

<PAGE>

      payee, the Administrative Agent shall promptly instruct the Collateral
      Agent to apply such proceeds in accordance with Section 6.1(n); and

provided that if any of the Subsidiaries of the Borrower shall fail to maintain
insurance in accordance with this Section 6.1(e), or if any of the Subsidiaries
of the Borrower shall fail to provide the required endorsements with respect
thereto, the Administrative Agent shall have the right (but shall be under no
obligation) to procure such insurance and the Borrower agrees to reimburse the
Administrative Agent for all reasonable costs and expenses of procuring such
insurance. All such policies as to which the Collateral Agent is named as an
additional insured or loss payee, as the case may be, shall (i) provide that the
same shall not be cancelled, materially modified or terminated for non-payment
of any premium without at least ten (10) days' prior written notice to each
insured and each loss payee named therein (for war risks coverage, seven (7)
days or such lesser period as is customarily available), (ii) where commercially
available, contain a breach-of-warranty clause providing that the respective
interests of the Collateral Agent or any other additional insured or loss payee
shall not be invalidated by any action or inaction of the Collateral Agent, the
Lenders, the Administrative Agent or any other Person, (iii) insure the
Collateral Agent and any other additional insured or loss payee regardless of
any breach or violation by the Borrower or any of its Subsidiaries or any other
Person of any warranties, declarations, or conditions contained in the policies
related to such insurance, (iv) provide that the insurer thereunder waives all
right of subrogation against the Collateral Agent and waives any right of
set-off or counterclaim against the Collateral Agent and any other right of
deduction against the Collateral Agent, whether by attachment or otherwise;
provided, further, that the insurer may proceed against third parties at any
time and against the Borrower at such time as the Obligations are paid in full,
(v) be primary without right of contribution from any other insurance carried by
or on behalf of the Collateral Agent, any Lender or the Administrative Agent
with respect to any interest in the Collateral, (vi) provide that no Person
other than the Borrower or its Subsidiaries (or, to the extent an Airport
Authority is required under a Material Contract to pay premiums on behalf of the
Borrower or any of its Subsidiaries, such Airport Authority) shall have any
liability for any premiums with respect thereto, and (vii) provide that inasmuch
as the policies are written to cover more than one insured, all terms and
conditions, insuring agreements and endorsements, with the exception of limits
of liability, shall operate in the same manner as if there were a separate
policy covering each insured. The Administrative Agent shall not, by reason of
accepting, rejecting, approving or obtaining insurance incur any liability for
the existence, nonexistence, form or legal sufficiency thereof, the solvency of
any insurer, or the payment of any losses.

All proceeds of insurance policies provided or obtained by the Borrower or any
of its Subsidiaries (whether or not required to be carried under the Loan
Documents) other than with respect to coverage for business interruption,
anticipated loss in revenue, workers' compensation, employees' liability and
general liability, in respect of any Material Loss shall be paid by the
respective insurers directly to the Loss Proceeds Account or, if received by the
Borrower or any such Subsidiary, shall promptly be transferred to the Loss
Proceeds Account and disbursed in accordance with Section 6.2(n).

            (f) Governmental Charges and Other Indebtedness. The Borrower shall,
and shall cause each of its Subsidiaries to, promptly pay and discharge when
due, or to the extent taxes are being filed and paid on a consolidated basis,
shall ensure that MIC promptly pays and

                                       52

<PAGE>

discharges when due, (i) all taxes and other Governmental Charges prior to the
date upon which penalties accrue thereon, (ii) all Indebtedness which, if
unpaid, could become a Lien upon the Property of such Loan Party and (iii)
subject to any subordination provisions applicable thereto, all other
Indebtedness which in each case, if unpaid, is reasonably likely to have a
Material Adverse Effect, except such Indebtedness, taxes or Governmental Charges
as may in good faith be contested or disputed, or for which arrangements for
deferred payment have been made; provided that in each such case appropriate
reserves are maintained to the reasonable satisfaction of the Administrative
Agent and no material Property of any such Loan Party is at impending risk of
being seized, levied upon or forfeited.

            (g) Use of Proceeds. The Borrower shall use the proceeds of the
Loans only for the respective purposes set forth in Section 2.6. The Borrower
shall not use any part of the proceeds of any Loan, directly or indirectly, for
the purpose of purchasing or carrying any Margin Stock or for the purpose of
purchasing or carrying or trading in any securities under such circumstances as
to involve the Borrower, any Lender or the Administrative Agent in a violation
of Regulations T, U or X issued by the Federal Reserve Board.

            (h) General Business Operations. The Borrower shall, and shall cause
each of its Subsidiaries to (i) preserve, renew and maintain in full force its
legal existence and good standing under the Governmental Rules of the
jurisdiction of its organization and each other jurisdiction where the failure
to so preserve, renew or maintain could result in a Material Adverse Effect, and
all of its rights, licenses, leases, qualifications, privileges franchises and
other authority reasonably necessary to the conduct of its business, (ii)
conduct its business activities in compliance with all Legal Requirements and
Contractual Obligations applicable to such Person, (iii) keep all Property
useful and necessary in its business in good working order and condition,
ordinary wear and tear excepted and from time to time make, or cause to be made,
all necessary and proper repairs, except, in each case, where any failure,
either individually or in the aggregate, could not reasonably be expected to
have a Material Adverse Effect, (iv) maintain, preserve and protect all of its
rights to enjoy and use material trademarks, trade names, service marks,
patents, copyrights, licenses, leases, franchise agreements and franchise
registrations, (v) obtain and maintain all Governmental Authorizations that are
required of the Borrower and its Subsidiaries for the validity and
enforceability of the Loan Documents and the operation of the airport services
businesses pursuant to the Material Contracts, except where the failure to do so
could not reasonably be expected to have a Material Adverse Effect, and (vi)
conduct its business in an orderly manner without voluntary interruption. The
Borrower shall maintain its chief executive office and principal place of
business in the United States.

            (i) Compliance with Legal Requirements and Contractual Obligations;
Enforcement of Material Contracts. The Borrower shall, and shall cause each of
its Subsidiaries to, (A) comply with all applicable Legal Requirements,
including all applicable Environmental Laws, and Contractual Obligations
noncompliance with which could reasonably be expected to have, either
individually or in the aggregate, a Material Adverse Effect, and (B) perform and
observe, in all material respects, the terms and provisions of each Material
Contract to be performed or observed by any of the Borrower or its Subsidiaries
and enforce their respective rights under the Material Contracts in accordance
with their applicable terms to the extent a failure to enforce such rights can
reasonably be expected to result in a material detriment to the Borrower or its
Subsidiaries or the Business.

                                       53

<PAGE>

            (j) Additional Collateral. If at any time from and after the Closing
Date any of the Borrower or its Subsidiaries acquires any fee or leasehold
interest in real property, such Loan Party shall deliver to the Administrative
Agent, at its own expense, as soon as possible all documentation and information
in form and substance reasonably satisfactory to the Administrative Agent
(including any environmental reports) relating thereto, and shall assist the
Administrative Agent in obtaining a deed of trust or mortgage on such real
property interest; provided that if such Loan Party is unable, after using
commercially reasonable efforts (as determined by it in good faith), to obtain
any required consent of an Airport Authority for the grant of a deed of trust or
mortgage in a leasehold interest in a lease for a fixed base operation, such
deed of trust or mortgage shall not be required under this Clause (j).

            (k) New Subsidiaries. The Borrower shall, at its own expense,
promptly, and in any event within ten (10) Business Days after the formation or
acquisition of any new direct or indirect Subsidiary of the Borrower after the
date hereof (i) notify the Administrative Agent of such event, (ii) amend the
Security Documents as appropriate in light of such event to pledge to the

Collateral thereby free and clear of all Liens, accompanied by undated stock

date hereof to guarantee the Obligations pursuant to documentation which is in

date hereof to execute a pledge and security agreement in form and substance
satisfactory to the Administrative Agent, (vi) cause each document (including
each Uniform Commercial Code financing statement and each filing with respect to
intellectual property owned by each such Person that becomes a direct or
indirect Subsidiary of the Borrower after the date hereof) required by law or
reasonably requested by the Administrative Agent to be filed, registered or
recorded in order to create in favor of the Collateral Agent for the benefit of
the Secured Parties a valid, legal and perfected first-priority security
interest in the Collateral subject to the Security Documents to be so filed,
registered or recorded and evidence thereof delivered to the Administrative

property if the Administrative Agent determines that such property is not
material to the business of such Subsidiary), and (vii) deliver an opinion of
counsel in form and substance satisfactory to the Administrative Agent with
respect to each such Person and the matters set forth in this clause (k).

            (n) Event of Loss.

                  (i) The Borrower shall promptly notify the Administrative
      Agent upon the Borrower having Actual Knowledge of any Event of Loss that
      the Borrower believes will be a Material Loss. The Administrative Agent
      shall be entitled at its option to consult in any compromise, adjustment
      or settlement in connection with any Event of Loss under any policy or
      policies of insurance or any proceeding with respect to any condemnation
      or other taking of property of the Borrower or otherwise involving a
      Material Loss, and, with respect to any Material Loss, the Borrower shall
      within five (5) Business Days after the Administrative Agent's request
      reimburse the Administrative Agent for all out-of-pocket expenses
      (including reasonable attorneys' and experts' fees) incurred by the
      Administrative Agent in connection with such participation.

                  (ii) If a Material Loss occurs, unless the appropriate Loan
      Party elects not to restore such Property and such restoration, repair,
      replacement or rebuilding is not required under Prudent Industry Practice
      to operate and maintain such Loan Party's business operations at the
      applicable airport (in which event the Net Insurance Proceeds or Net
      Condemnation Proceeds, as the case may be, shall be applied to a mandatory
      prepayment of the Loans in accordance with Section 2.8(c)(iv)), the
      Borrower shall promptly (and in any event within 30 days after the
      occurrence of the Event of Loss) deliver to the Administrative Agent a
      Restoration Plan and, upon approval thereof by the Administrative Agent,
      commence and diligently pursue the Restoration. If the plan of restoration
      as submitted by the Borrower does not qualify as a Restoration Plan or is
      not approved by the Administrative Agent in accordance with this clause,
      the Borrower and the Administrative Agent shall enter into negotiations in
      good faith with a view to agreeing on mutually acceptable terms of the
      Restoration Plan.

                  (iii) Funds on deposit in the Loss Proceeds Account that are
      to be made available for restoration work pursuant to a Restoration Plan
      as set forth in clause (ii) above will be disbursed to pay the cost of the
      Restoration upon receipt by the Administrative Agent of a certificate of
      the Borrower certifying that: (A) all of the restoration work already
      completed was done substantially in compliance with the approved
      Restoration Plan, (B) the sum requested is required to pay for costs
      incurred in connection with such restoration work (giving a description of
      the services and materials provided in connection with such restoration
      work), (C) the sum requested, when added to all amounts with respect to
      the relevant casualty event previously paid out of the Concentration
      Account or by the applicable Loan Party out of its Operating Accounts,
      does not exceed the aggregate amount then due and payable with respect to
      the restoration work done as of the date of such certificate, (D) the
      amount of net proceeds with respect to the Event of Loss remaining in the
      Concentration Account or the applicable Loan Party's Operating Accounts,
      together with any other amounts deposited in such accounts by the Borrower
      or any other Person or otherwise irrevocably committed to be made
      available to the Borrower as equity funds or Permitted

      Subordinated Debt (in each case, by the Investor or an Affiliate thereof
      or a Person that has at least an investment grade long-term unsecured (and
      not credit enhanced) debt rating or other credit status satisfactory to
      the Required Lenders) for the purpose of such restoration are anticipated
      to be sufficient to complete the restoration work in accordance with the
      Restoration Plan, (v) there exists no mechanic's, materialmen's or other
      Liens on the affected Property arising out of the Restoration (except
      which are not yet due, adequately bonded, Permitted Liens or as are being
      contested pursuant to Permitted Contest Provisions), or if the same do
      exist, they will be discharged with the funds received from the requested
      payment, and (vi) no Default or Event of Default has occurred and is
      continuing.

            (o) Environmental Management System. The Borrower shall cause all of
its Subsidiaries to conduct their respective business operations in compliance
with the environmental management system presently in place for the Borrower's
businesses, which environmental management system shall at all times incorporate
at least the following elements: a board-approved environmental policy;
designated personnel assigned to assess, achieve and maintain material
compliance with Environmental Laws; a reporting system to ensure monitoring and
oversight by management; systematic record keeping and management review of
budgets and expenses relating to cleanup and compliance with Environmental Laws;
plans, policies and procedures for complying with customary management practices
for maintenance, inspection and management of hazardous materials in the
workplace, including as applicable asbestos-containing materials, lead-based
paint, lead in drinking water and radon. The Borrower shall certify the
completeness and implementation of such a program on or before one hundred
eighty (180) days after the Closing Date. Upon the Administrative Agent's
reasonable request, and at the Borrower's sole cost and expense, the Borrower
shall obtain and provide to the Administrative Agent a written evaluation of an
environmental consulting firm reasonably acceptable to the Administrative Agent,
confirming that the environmental management system is reasonable and customary,
and could reasonably be expected to identify, remedy and manage material
environmental liabilities and/or cleanup obligations.

            (p) Further Assurances. The Borrower, at its own cost, expense and
liability, will cause to be promptly and duly taken, executed, acknowledged and
delivered all such further acts, documents and assurances as may be reasonably
necessary in order to carry out the intent and purposes of this Agreement and
the other Loan Documents, and the transactions contemplated hereby and thereby.

            (q) Cash Management Procedures; Payments to Reserve Accounts.

                  (i) The Borrower hereby confirms that its Subsidiaries have
      previously established in the respective names of such Subsidiaries the
      bank accounts listed as "OPERATING ACCOUNTS" specified on Schedule 5.26
      (each such account, an "OPERATING ACCOUNT"). The Borrower and its
      Subsidiaries shall maintain or cause to be maintained the Operating
      Accounts, and shall deposit or cause to be deposited into the Operating
      Accounts all Operating Revenues and all other amounts received by the Loan
      Parties from any source whatsoever, in each case, promptly upon receipt
      thereof. Each Operating Account shall be linked to the Concentration
      Account and cash from each Operating Account shall be transferred into the
      Concentration Account on a daily (or, as

                                       56

<PAGE>

      agreed to with the Administrative Agent, weekly) basis. None of the
      Operating Accounts may be closed unless the funds then on deposit in such
      Account are transferred to another Operating Account or to a new Operating
      Account established and maintained in accordance with clause (ii) below.

                  (ii) Any Subsidiary of the Borrower may establish additional
      Operating Accounts as necessary or desirable for its business; provided
      that if an Operating Account is established with a bank with which such
      Subsidiary does not maintain an Operating Account as of the Closing Date,
      such bank shall be organized under the laws of the United States of
      America or any state thereof having a combined capital and surplus of not
      less than $500,000,000, unless the Administrative Agent consents to such
      bank. Any new bank with which an Operating Account shall be established
      shall be required, upon the opening of such Operating Account, to (i)
      enter into a Control Agreement, substantially in the form of Exhibit F
      hereto with such changes thereto as may be requested or approved by the
      Administrative Agent and the Borrower (or such other form as is reasonably
      acceptable to the Administrative Agent, such bank and the Borrower), with
      the Borrower and the Collateral Agent and carry out such further acts as
      the Administrative Agent may reasonably request in order to perfect the
      security interest of the Collateral Agent in the relevant accounts and
      (ii) agrees to provide monthly and annual statements as to such Operating
      Account to the Administrative Agent concurrently with the delivery thereof
      to the applicable Subsidiary. If an Operating Account is established with
      a bank with which a Subsidiary of the Borrower already maintains an
      Operating Account, such bank shall be required, upon the opening of such
      Operating Account, to enter into an amendment to the existing Control
      Agreement to which it is a party with such changes thereto as are required
      or may be requested by the Administrative Agent in order to perfect the
      security interest of the Collateral Agent in such Operating Account.

                  (iii) The Borrower shall cause amounts held in the
      Concentration Account to be withdrawn and transferred at the following
      times and for the following purposes:

                  (A) On each Quarterly Funds Transfer Date, the Borrower shall
            cause to be transferred to the Debt Service Reserve Account from
            available Excess Cash Flow an amount equal to, if a positive number,
            (A) the then current Debt Service Reserve Required Balance, minus
            (B) the funds then on deposit in the Debt Service Reserve Account.

                  (B) The Borrower shall cause to be transferred to the Special
            Reserve Account such amounts of Excess Cash Flow, after application
            of amounts in accordance with the preceding clause (A) and in such
            manner as are required pursuant to Sections 6.2(f)(ii) and
            6.2(f)(iii).

                  (C) Subject to Sections 2.8(c)(v) and 2.8(c)(vi), promptly
            (and in any event within five (5) Business Days) after the Debt
            Service Coverage Ratio has been calculated for each fiscal quarter
            of the Borrower, the Borrower shall cause to be transferred to the
            Distribution Account all Cash Available for Distribution;

                                       57

<PAGE>

            provided that if the Borrower is permitted to make a Distribution of
            such amounts to the Investor in accordance with Section 6.2(f)(i),
            such amounts may be paid by the Borrower directly to the Investor.

                  (iv) The Borrower and the other Loan Parties hereby agree that
      the Administrative Agent is authorized to withdraw and transfer funds from
      the Concentration Account to effect the payments described in paragraphs
      (A), (B) and (C) above in the event the Borrower does not cause such funds
      to be transferred in a timely or otherwise appropriate manner; provided
      that the Borrower shall under no circumstances be relieved from its
      obligations under Section 6.1(q)(iii).

            (r) Assignment of Material Contracts. As promptly as possible after
the Closing Date, the Borrower shall request, or shall cause each relevant
Subsidiary to request, in writing, and the Borrower shall use, or shall cause
each relevant Subsidiary to use, all commercially reasonable efforts to obtain
from each Airport Authority, a written consent with respect to the collateral
assignment of the relevant Subsidiary's interest in each FBO Lease, to the
extent required under the terms of such FBO Lease. The Borrower hereby agrees
that to the extent any such consent is obtained, it shall promptly following
receipt thereof (and in any event, no later than ten (10) Business Days
thereafter) and at its own cost and expense, cause the execution and recording
of a leasehold deed of trust or mortgage relating to such FBO Lease, and deliver
to the Collateral Agent any and all agreements, documents, instruments, filings
and writings deemed necessary by the Collateral Agent, or as the Collateral
Agent may reasonably request from time to time in its sole discretion, to
evidence, perfect or protect the Secured Parties' rights and security interests
in and to the FBO Leases. The Borrower hereby authorizes the Collateral Agent to
execute, deliver and file any such agreement, document, instrument, filing or
writing.

            (s) Debt Service Reserve Required Balance.

                  (i) Subject to clause (ii) below, the Borrower shall deposit
      to the Debt Service Reserve Account funds equal to an amount which results
      in such account being funded with the Debt Service Reserve Required
      Balance as required hereunder and shall thereafter transfer funds to the
      Debt Service Reserve Account in accordance with Section 6.1(q)(iii)(A).

                  (ii) The Borrower shall be permitted to maintain the Debt
      Service Reserve Required Balance by any combination (except as otherwise
      provided in clause (iii) below) of available cash on deposit in the Debt
      Service Reserve Account and a Debt Service Reserve Letter of Credit
      maintained in effect by the Borrower; provided that the Debt Service
      Reserve Letter of Credit shall not be a Letter of Credit issued under the
      Letter of Credit Facility. The Borrower shall notify the Administrative
      Agent at least forty-five (45) days prior to the expiration of the Debt
      Service Reserve Letter of Credit provided pursuant to this Section 6.2(s).
      Any Debt Service Reserve Letter of Credit shall be unconditionally
      drawable by the Administrative Agent if any of the following occurs: (A)
      in the event, and to the extent, of any shortfall in the payment of
      Mandatory Debt Service when due; (B) in the event the entity that has
      issued the Debt Service Reserve Letter of Credit suffers an L/C Issuer

      acceleration of the Loans and/or exercise of remedies under the Security
      Documents.

                  (iii) Upon the occurrence of an L/C Issuer Event (and provided
      that the Administrative Agent shall not have drawn the full amounts
      available thereunder), the Borrower shall replace any letter of credit
      affected thereby by depositing cash to the Debt Service Reserve Account or
      providing a letter of credit issued by an Acceptable Issuer not later than
      three (3) Business Days after the earlier of (A) the Collateral Agent
      giving the Borrower written notice thereof and (B) the Borrower having
      Actual Knowledge thereof.

                  (iv) Upon the satisfaction in full of the Obligations, the
      Debt Service Reserve Letter of Credit will be forthwith returned to the

            (v) Pledge of Equity Interests in Subsidiaries. The Borrower shall
use all commercially reasonable efforts to obtain the consent of an Airport
Authority for the pledge of the Equity Securities of any of Trajen's
Subsidiaries that is a party to a Trajen FBO Lease to the extent such consent is
required thereunder. If the Borrower is unable to obtain such consent within 30
days after the Trajen Acquisition Term Loan Disbursement Date, the Borrower

wholly-owned by a single-purpose entity owning only the stock of such Subsidiary
(which entity shall also be a Subsidiary of the Borrower). The Equity Securities
of each such immediate parent entity shall be pledged in favor of the Collateral
Agent to secure the Obligations.

            (w) Disposal of Aviation Maintenance Services Business. The Borrower
shall use commercially reasonable efforts to sell, assign, convey and transfer,

FBO Leases and the terms of all applicable law and Governmental Authorizations,
to a reputable entity or entities possessing reasonably sufficient experience
operating similar services in accordance with prudent industry standards for
work of similar scope and scale, and under arrangements whereby the Borrower and
its Subsidiaries are not responsible or liable for such services following such
sale. Without limiting the foregoing, if such sale is not consummated within
ninety (90) days following the Closing Date, the Borrower shall arrange for the
transfer of the Maintenance Services Businesses and related assets, together
with capitalization sufficient for the operations and conduct of such
businesses, including the carrying and maintenance of insurance of the types, in
the amounts and subject to such deductibles and other terms customarily carried
from time to time by others engaged in substantially the same business as the
Maintenance Services Business and in accordance with prevailing prudent industry
standards, so as to cause such services to be held and provided by a new
Subsidiary or group of Subsidiaries in a manner that minimizes the exposure of
the Borrower or any of its other Subsidiaries to liability resulting from the
conduct of such businesses.

      Until the termination of the Commitments and the satisfaction in full by

<PAGE>

                  (iii) Guarantee obligations of the Borrower or any of its
      Subsidiaries in respect of Permitted Indebtedness of any of the Borrower

Loan Party in any Loan Document to which it is a party, or in any certificate or
document delivered to the Administrative Agent or the Collateral Agent by the
Borrower or any other Loan Party pursuant to any Loan Document, shall prove to
have been incorrect when made or deemed made and a Material Adverse Effect would
reasonably be expected to result therefrom; or

any payment on account of any Indebtedness of such Person (other than the
Obligations or Permitted Subordinated Indebtedness) when due (whether at
scheduled maturity, by required prepayment, upon acceleration or otherwise) and
such failure shall continue beyond any grace period provided with respect
thereto, if the amount of such Indebtedness exceeds $500,000 or the effect of
such failure is to cause, or permit the holder or holders thereof to cause, such
Indebtedness of the Borrower or any of its Subsidiaries (other than the
Obligations or Permitted Subordinated Indebtedness) in an aggregate amount
exceeding $500,000 to become redeemable, liquidated, due or otherwise payable

condition is to cause, or permit the holder or holders thereof to cause, such
Indebtedness of the Borrower or any of its Subsidiaries (other than the
Obligations or Permitted Subordinated Indebtedness) in an aggregate amount
exceeding $500,000 to become redeemable, liquidated, due or otherwise payable
(whether at scheduled maturity, by required prepayment, upon acceleration or
otherwise) and/or to be secured by cash collateral; or

in such Material Contract, and such failure continues for a period of 30 days
after notice from the Administrative Agent or, if the failure is capable of
remedy, such longer period as may be agreed to between the Administrative Agent
in its discretion and the applicable Loan Party so long as the applicable party
is diligently pursuing such remedy and such extension of time does not or could
not reasonably be expected to result in a Material Adverse Effect; provided that
any such event occurring with respect to a party other than a Loan Party shall

Loan Parties (determined on a consolidated basis) as conducted as of the Closing
Date, shall be revoked, terminated, withdrawn, suspended or materially modified,
unless such Governmental Authorization is reinstated within ten (10) days after
the occurrence of such event (or such longer period as is necessary to reinstate
such Governmental Authorization, so long as the applicable Loan Party is
diligently pursuing such reinstatement and such extension of time does not
result or could reasonably be expected to result in a Material Adverse Effect);
or

            (s) any substantial portion of the Property of the Borrower or any
of its Subsidiaries (determined on a consolidated basis) is seized, condemned,
nationalized or appropriated without fair value being paid therefor (or made up
through equity contributions) so as to allow replacement of such Property and/or
prepayment of Obligations and to allow the Borrower in the Administrative
Agent's reasonable judgment to continue satisfying its obligations hereunder and
under the other Loan Documents; or

            (t) the Backward Debt Service Coverage Ratio shall be less than or
equal to 1.20 to 1.00 as of the end of any fiscal quarter of the Borrower, or

Leverage Ratio Test Period is greater than the Applicable Leverage Ratio for
such period; or

            (u) any event or condition involving loss, liability, damage or

condition could reasonably be expected to have a Material Adverse Effect.

      Any Event of Default referred to in Section 7.1(o), (p) or (q) affecting
one or more FBOs (other than a Non-Eligible FBO) may, at any time prior to
acceleration of the Loans under Section 7.2(a)(ii), be cured by prepayment in
accordance with Section 2.8(b) of a portion of the Term Loans equal to (i) the
Term Loans outstanding as of the date on which such Event of

                                       72

<PAGE>

Default occurred multiplied by (ii) the Proportional EBITDA Contribution of such
FBO(s), whereupon the Borrower Subsidiary or Borrower Subsidiaries party to the
FBO Leases at the affected FBO locations shall be released from the Loan
Documents; provided that such method of cure may be exercised as to any FBO only
if the Proportional EBITDA Contribution of such FBO, when added to the
Proportional EBITDA Contribution of any other FBO(s) as to which such method of
cure is concurrently exercised, does not exceed the Maximum Release Percentage.
Any such prepayment shall be made solely out of Cash Available for Distribution
as of the end of the most recent fiscal quarter of the Borrower or from new
equity contributions from the Investor to the Borrower, or a combination
thereof. For the avoidance of doubt, the cure right permitted by this paragraph
shall not be available with respect to the Non-Eligible FBOs, and may not be
exercised more than once during the period from the Refinancing Term Loan
Disbursement Date through and including the date on which all Obligations have
been indefeasibly paid in full and the Commitments under this Agreement have
terminated.

      Section 7.2. Remedies Upon Event of Default.

            (a) If any Event of Default occurs and is continuing, the
Administrative Agent may, and upon the request of the Required Lenders shall:
(i) by notice to the Borrower, declare the Commitments to be terminated,
whereupon the same shall forthwith terminate (except that any such termination
shall not affect the obligation of each Revolving Loan Lender to reimburse the
Issuing Bank in respect of any Drawing under a Letter of Credit issued pursuant
to Section 2.13 prior to such termination); (ii) by notice to the Borrower,
declare the entire unpaid principal amount of the Loans (together with all
accrued and unpaid interest thereon and any other amount then due under the Loan
Documents) and all other Obligations to be forthwith due and payable, whereupon
such amounts shall become and be forthwith due and payable, without presentment,
demand, protest, or notice of any kind, all of which are hereby expressly waived
by the Borrower; and/or (iii) instruct the Collateral Agent to foreclose on any
or all of the Collateral and/or proceed to enforce all remedies available to the
Administrative Agent (or Collateral Agent) pursuant to the Loan Documents or
otherwise as a matter of law. Notwithstanding the foregoing, if an Event of
Default referred to in Section 7.1(i) or (j) shall occur with respect to the
Borrower, automatically and without notice the actions described in clauses (i)
and (ii) above shall be deemed to have occurred.

            (b) Without limiting the rights of the Administrative Agent set
forth in paragraph (a) above or elsewhere in this Agreement, if any Event of
Default or Revolver Event of Default occurs and is continuing, the Revolving
Loan Lender (with respect to the Revolving Loans only and irrespective of any
action or inaction taken with respect to the Term Loans) may, by notice to the
Borrower (in the case of a Revolver Event of Default which is not otherwise an
Event of Default, given not later than fifteen (15) days of the Revolving Loan
Lender receiving written notice of the occurrence of such Revolver Event of
Default), (i) declare the Revolving Loan Commitments to be terminated, whereupon
the same shall forthwith terminate (except that any such termination shall not
affect the obligation of the Revolving Loan Lender to reimburse the Issuing Bank
in respect of any Drawing under a Letter of Credit issued pursuant to Section
2.13 prior to such termination); and/or (ii) declare the entire unpaid principal
amount of the Revolving Loans (together with all accrued and unpaid interest
thereon and any other amount then due under the Loan Documents) and all other
Obligations owing to the Revolving Loan Lender to be forthwith due and payable,
whereupon such amounts shall become and be forthwith

                                       73

<PAGE>

due and payable, without presentment, demand, protest, or notice of any kind,
all of which are hereby expressly waived by the Borrower. Any such acceleration
of the Obligations owed to the Revolving Loan Lender shall not alter or affect
the limitations on remedies specified in paragraph (c) below.

            (c) Subject to paragraph (d) below, no Financing Party may, except
with the prior consent of the Required Lenders (i) enforce any security interest
created or evidenced by any Security Document or require the Administrative
Agent to enforce any such security interest (provided that the foregoing shall
not limit any right of setoff by a Lender permitted hereunder); (ii) sue for or
institute any creditor's process (including an injunction, garnishment,
execution or levy, whether before or after judgment) in respect of any
Obligation (whether or not for the payment of money) owing to it under or in
respect of any Loan Document; (iii) take any step for the winding-up,
administration of or dissolution of, or any insolvency proceeding in relation
to, the Borrower, or for a voluntary arrangement, scheme of arrangement or other
analogous step in relation to the Borrower, or (iv) apply for any order for an
injunction or specific performance in respect of the Borrower in relation to any
of the Loan Documents.

            (d) If the Revolving Loans and interest thereon are not repaid in
full on the Maturity Date, the Revolving Loan Lender may bring any action or
proceeding (i) for collection of such unpaid amounts and other amounts due and
owing to the Revolving Loan Lender with respect thereto and (ii) for the
recognition or enforcement of any judgment with respect to such unpaid amounts
and such other amounts. Notwithstanding the foregoing, as long as any real
property is included in the Collateral, the Revolving Loan Lender shall not
exercise any rights or remedies that could reasonably be expected to result in
the loss of the Collateral Agent's Lien on the Collateral pursuant to the
California "one action" rule or any similar rule of any other jurisdiction.
Notwithstanding anything in the foregoing to the contrary, the Revolving Loans
shall at all times be secured by the Lien pursuant to the Security Documents,
subject to the direction of the Required Lenders.

      Section 7.3. Waiver of Event of Default.

      Any Event of Default may be waived as provided in Section 10.1. No waiver
of any Event of Default shall constitute a waiver of any other or any succeeding
Event of Default except to the extent specifically provided in such waiver.

                                  ARTICLE VIII

                              ADMINISTRATIVE AGENT

      Section 8.1. Appointment and Authorization of Administrative Agent.

      Each Financing Party hereby appoints, designates and authorizes the
Administrative Agent to take such action on its behalf under the provisions of
this Agreement and each other Loan Document and to exercise such powers and
perform such duties as are expressly delegated to it by the terms of this
Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative
Agent shall not have any

                                       74

<PAGE>

duties or responsibilities, except those expressly set forth herein, nor shall
the Administrative Agent have or be deemed to have any fiduciary relationship
with any Financing Party or participant, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable Legal Requirement. Instead, such term is used merely as a matter of
market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties.

      Section 8.2. Delegation of Duties.

      The Administrative Agent may execute any of its duties under this
Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel and other
consultants or experts concerning all matters pertaining to such duties. The
Administrative Agent shall not be responsible for the negligence or misconduct
of any agent or attorney-in-fact that it selects in the absence of gross
negligence or willful misconduct.

      Section 8.3. Liability of Administrative Agent.

      None of the Administrative Agent, its officers, directors, employees,
agents, attorneys-in-fact and Affiliates shall (a) be liable for any action
taken or omitted to be taken by any of them under or in connection with this
Agreement or any other Loan Document or the transactions contemplated hereby
(except for its own gross negligence or willful misconduct in connection with
its duties expressly set forth herein), or (b) be responsible in any manner to
any Financing Party or participant for any recital, statement, representation or
warranty made by any Loan Party or any officer thereof, contained herein or in
any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Administrative Agent
under or in connection with, this Agreement or any other Loan Document, or the
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document, or for any failure of any Loan Party or
any other party to any Loan Document to perform its obligations hereunder or
thereunder. None of the Administrative Agent and any of its officers, directors,
employees, agents, attorneys-in-fact and Affiliates shall be under any
obligation to any Financing Party or participant to ascertain or to inquire as
to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of any Loan Party or any Affiliate thereof.

      Section 8.4. Reliance by Administrative Agent.

      The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, electronic mail message, statement or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons, and upon advice
and

                                       75

<PAGE>

statements of legal counsel (including counsel to any Loan Party), independent
accountants and other experts selected by the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under any Loan Document unless it shall first receive such advice or
concurrence of the Required Lenders as it deems appropriate and, if it so
requests, it shall first be indemnified to its satisfaction by the Financing
Parties against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement or any other Loan Document in accordance with a request or
consent of the Required Lenders (or such greater number of Lenders as may be
expressly required hereby in any instance) and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders.

      Section 8.5. Notice of Default.

      The Administrative Agent shall not be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default, except with respect to
defaults in the payment of principal, interest and fees required to be paid to
the Administrative Agent for the account of the Financing Parties, unless the
Administrative Agent shall have received written notice from a Financing Party
or the Borrower referring to this Agreement, describing such Default and stating
that such notice is a "notice of default." The Administrative Agent will notify
the Financing Parties of its receipt of any such notice. The Administrative
Agent shall take such action with respect to such Default or Event of Default as
may be directed by the Required Lenders (or such other number or percentage of
Lenders as shall be necessary under the circumstances as provided in Section
10.1; provided, that unless and until the Administrative Agent has received any
such direction, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable or in the best interest
of the Financing Parties.

      Section 8.6. Credit Decision; Disclosure of Information.

      Each Financing Party acknowledges that neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates has made any representation or warranty to it, and that no act by the
Administrative Agent hereafter taken, including any consent to and acceptance of
any assignment or review of the affairs of any Loan Party or any Affiliate
thereof, shall be deemed to constitute any representation or warranty by the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates to any Financing Party as to any matter,
including whether the Administrative Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates have disclosed material
information in their possession. Each Financing Party represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates and based on such documents and information as
it has deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder. Each Financing Party also represents
that it will, independently and without reliance upon the

                                       76

<PAGE>

Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Borrower. Except for notices,
reports and other documents expressly required to be furnished to the Financing
Parties by the Administrative Agent herein, the Administrative Agent shall not
have any duty or responsibility to provide any Financing Party with any credit
or other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of the Borrower or any of its
Affiliates which may come into the possession of the Administrative Agent or any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

      Section 8.7. Indemnification.

      To the extent that the Borrower fails to pay any amount required to be
paid by it to the Administrative Agent or any Indemnitee, each Financing Party
severally agrees to pay to the Administrative Agent or such Indemnitee such
Financing Party's Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is sought) of such unpaid
amount. The undertaking in this Section 8.7 shall survive termination of the
Commitments, the payment of all Obligations and the resignation of the
Administrative Agent.

      Section 8.8. Administrative Agent in Its Individual Capacity.

      The Administrative Agent and its Affiliates may make loans to, issue
letters of credit for the account of, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial
advisory, underwriting or other business with each of the Loan Parties and their
respective Affiliates as though the Administrative Agent were not the
Administrative Agent hereunder and without notice to or consent of the Financing
Parties. The Financing Parties acknowledge that, pursuant to such activities,
the Administrative Agent or its Affiliates may receive information regarding any
Loan Party or its Affiliates (including information that may be subject to
confidentiality obligations in favor of such Loan Party or such Affiliate) and
acknowledge that the Administrative Agent shall be under no obligation to
provide such information to them. With respect to its Loans or other Credit
Exposure, the Administrative Agent shall have the same rights and powers under
this Agreement as any other Financing Party and may exercise such rights and
powers as though it were not the Administrative Agent.

      Section 8.9. Collateral Agency Agreement.

      Each Financing Party hereby authorizes the Administrative Agent and the
Collateral Agent to execute and deliver the Collateral Agency Agreement on
behalf of such Financing Party and agrees that, upon such execution and
delivery, such Financing Party shall be bound by the terms and provisions
thereof as if such Financing Party was a signatory thereto. Each Financing Party
further authorizes the Administrative Agent to exercise such powers and
discretion under each such agreement as are delegated to the Administrative
Agent by the terms thereof, together with such powers and discretion as are
reasonably incidental thereto. As to matters not expressly

                                       77

<PAGE>

provided for in the Collateral Agency Agreement, the Administrative Agent shall
not be required to exercise any discretion or take any action, but shall be
required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Required Lenders;
provided that the Administrative Agent shall not be required to take any action
that exposes it to personal liability or that is contrary to the Loan Documents
or applicable Legal Requirements.

      Section 8.10. Successor Administrative Agent.

      The Administrative Agent may resign as Administrative Agent upon 30 days'
prior written notice to the Lenders, and the Administrative Agent may be removed
at any time for cause by the Required Lenders. If the Administrative Agent
resigns under this Agreement or if the Administrative Agent is removed, the
Required Lenders shall appoint from among the Lenders a successor administrative
agent for the Lenders, which successor administrative agent shall be consented
to by the Borrower at all times other than during the existence of an Event of
Default (which consent of the Borrower shall not be unreasonably withheld or
delayed). If no successor administrative agent is appointed prior to the
effective date of the resignation or removal of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Lenders and the
Borrower, a successor administrative agent from among the Lenders. Upon the
acceptance of its appointment as successor administrative agent hereunder, the
Person acting as such successor administrative agent shall succeed to all the
rights, powers and duties of the retiring Administrative Agent and the term
"Administrative Agent" shall mean such successor administrative agent, and the
retiring Administrative Agent's appointment, powers and duties as Administrative
Agent shall be terminated. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative Agent, the provisions of this Article
VIII and Section 10.3 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement. If no successor administrative agent has accepted appointment as
Administrative Agent by the date which is 30 days following a retiring
Administrative Agent's notice of resignation or removal, the retiring
Administrative Agent's resignation or removal shall nevertheless thereupon
become effective and the Lenders shall perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above.

      Section 8.11. Lead Arrangers.

      The Lead Arrangers shall not have any right, power, obligation, liability,
responsibility or duty under this Agreement other than, to the extent it is a
Lender or the Administrative Agent, those applicable to all Lenders or the
Administrative Agent, as the case may be, as such. Each Lender acknowledges that
it has not relied, and will not rely, on the Lead Arrangers in deciding to enter
into this Agreement or in taking or not taking action hereunder.

                              HEDGING ARRANGEMENTS

      Section 9.1. Hedging Payments.

      Each Hedging Bank agrees that it shall not (i) demand (other than as may
be necessary in order to exercise any right to terminate any Hedging Transaction
pursuant to a Hedging Agreement as permitted under Section 9.2 or required under
Section 9.3) or receive payment, prepayment or repayment of, or any distribution
in respect of, or on account of, any of the Hedging Obligations in cash or in
kind, or apply any money or property in or towards the discharge of any Hedging
Obligations except for scheduled payments arising under the terms of the Hedging
Agreements, or (ii) permit to exist or receive any security interest or any
financial support (including the giving of any guarantee or the making of any
deposit or payment) for or in respect of any of the Hedging Obligations other
than under the Loan Documents.

      Section 9.2. Voluntary Termination.

      Each Hedging Bank agrees that it may terminate a Hedging Transaction
pursuant to a Hedging Agreement only upon the occurrence of any of the following
events: (i) the Administrative Agent has declared that all of the amounts
outstanding under the Loan Documents are immediately due and payable or such
acceleration has occurred without notice from the Administrative Agent pursuant
to Section 7.2(a), (ii) the Required Lenders have directed the Administrative

by the Hedging Bank in the event it becomes unlawful for such Hedging Bank to

            (b) If the aggregate notional amounts hedged under the Hedging
Agreements exceed by more than ten percent (10%) of the aggregate principal

Security Documents.

      By entering into a Hedging Agreement entitling it to the benefits of the

are in compliance with this Agreement, each Hedging Agreement shall be secured
by the Liens created by the Security Documents on a pari passu basis.

      Section 10.1. Amendments; Waivers.

            (a) No amendment or waiver of any provision of this Agreement or any
other Loan Document, and no consent to any departure by the Borrower or any
other Loan Party therefrom, shall be effective unless in writing signed by the
Required Lenders and the Borrower or other applicable Loan Party, as the case
may be, and acknowledged by the Administrative Agent; provided that no such
amendment, waiver or consent shall: (i) extend or increase the Commitment of any
Lender without the written consent of such Lender; (ii) postpone any date fixed
by this Agreement or any other Loan Document for any payment or mandatory
prepayment of principal, interest, fees or other amounts due to the Lenders (or
any of them), or postpone the scheduled date of expiration of any Commitment,
without the written consent of each Lender directly affected thereby; (iii)
reduce the principal of, or the rate of interest specified herein on, any Loan,
or any fees or other amounts payable hereunder or under any other Loan Document,
or change any financial ratio or the manner of calculation of any financial
ratio (including any change in any applicable defined term) used in determining
the amount of any mandatory prepayment that would result in a reduction of any
such prepayment, without the written consent of each Lender directly affected
thereby; (iv) change Section 2.12 in a manner that would alter the pro rata
sharing of payments required thereby without the written consent of each Lender;
(v) change any provision of this Section 10.1 or the definition of "Required
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder, without the written consent of
each Lender; (vi) release any Guarantor from the Subsidiary Guaranty, or (vii)
release all or any material part of the Collateral without the written consent
of each Lender and Hedging Bank (except that (A) any release in connection with
a sale or other disposition of Collateral authorized by Section 6.2(c) shall not
require the approval of any Lender or Hedging Bank) and (B) any amendment,
waiver or consent which modifies the terms of Section 6.2(c) (including any
modification relating to the prepayment of proceeds from any such sale or other
disposition) shall require the consent of the Required Lenders); and provided,
further, that (A) no amendment, waiver or consent shall, without the written
consent of the Administrative Agent in addition to the Lenders required above,
affect the rights or duties of the Administrative Agent under this Agreement or
any other Loan Document, (B) no amendment, waiver or consent shall, without the
written consent of the Issuing Bank in addition to the Lenders required above,
affect the rights or duties of the Issuing Bank under this Agreement or

                                       80

<PAGE>

any other Loan Document (C) no amendment, waiver or consent shall, without the
written consent of each Hedging Bank directly affected thereby in addition to
the Lenders required above, affect the rights or duties of such Hedging Bank
under this Agreement or any other Loan Document, and (D) any separate fee
agreement between the Borrower and the Administrative Agent in its capacity as
such or between the Borrower and the Lead Arrangers in their capacities as such
may be amended or modified by such parties; and provided, further, that any
waiver of conditions precedent set forth in Section 4.1(h) or Section 4.3(k)
which relate to the perfection of a security interest in Collateral can be
waived by the Administrative Agent in its discretion, provided that such
condition shall instead be satisfied after the applicable Disbursement Date, and
within time periods established by the Administrative Agent in its discretion;
and provided, further, that (A) no amendment, waiver or consent shall, without
the written consent of the Revolving Loan Lender, in addition to the Lenders
required above, be effective for purposes of determining the obligation of the
Revolving Loan Lender to make Revolving Loans or the existence or non-existence
of a Revolver Event of Default, or the rights of the Revolving Loan Lender
specified in Section 7.2(b), and (B) no amendment, waiver or consent shall,
without the written consent of the Issuing Bank, in addition to the Lenders
required above, be effective for purposes of determining the obligation of the
Issuing Bank to issue Letters of Credit.

            (b) No failure or delay by the Administrative Agent or any Lender in
exercising any right or power hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent and the
Lenders hereunder are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (a) of this Section
10.1, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of
the foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent or any Lender may have
had notice or knowledge of such Default at the time.

      Section 10.2. Notices.

            (a) Unless otherwise expressly provided herein, (and subject to

The effectiveness of any such documents and signatures shall, subject to
applicable Legal Requirements, have the same force and effect as manually-signed
originals and shall be binding on all Loan Parties, the Administrative Agent and
the Lenders. The Administrative Agent may also require that any such documents
and signatures be confirmed by a manually-signed original thereof; provided that
the failure to request or deliver the same shall not limit the effectiveness of
any facsimile document or signature.

            (c) Electronic mail and internet and intranet websites may be used
only to distribute routine communications, such as Financial Statements and
other information as provided in Section 6.1(a), and to distribute Loan
Documents for execution by the parties thereto, and may not be used for any
other purpose.

            (d) Any party hereto may change its address or telecopy number for
notices and other communications hereunder by notice to the Borrower and the

      Section 10.3. Expenses; Indemnity; Damage Waiver.

            (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Administrative Agent and the Collateral Agent, including the
reasonable fees, charges and disbursements of counsel for the Administrative
Agent and the Collateral Agent, in connection with the preparation, negotiation
and execution of this Agreement and the other Loan Documents and any amendment,
modification or waiver of the provisions hereof or thereof (whether or not the
transactions contemplated hereby or thereby shall be consummated), the
syndication of the credit facilities provided for herein, and administration of
the transactions contemplated hereby and thereby, and (ii) all reasonable
out-of-pocket expenses incurred by the Administrative Agent, the Collateral
Agent or any Lender, including the fees, charges and disbursements of any
counsel for the Administrative Agent or the Collateral Agent, in connection with

reasonable out-of-pocket expenses incurred during any workout,

restructuring or negotiations in respect of the Obligations; provided that the
Borrower shall not be liable for the expenses of separate counsel to any Lender.

            (b) The Borrower shall indemnify the Administrative Agent, each
Lender and the Issuing Bank, and each of the officers, directors, employees,
agents, attorneys-in-fact and Affiliates of any of the foregoing Persons (each
such Person being called an "INDEMNITEE") against, and hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related
expenses, including the fees, charges and disbursements of any counsel for any
Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with, or as a result of (i) the execution or delivery of any Loan
Document or any agreement or instrument contemplated thereby, the performance by
the parties hereto of their respective obligations hereunder or thereunder or
the consummation of the transactions contemplated thereby, (ii) any Commitment,
Loan or Letter of Credit issued pursuant to Section 2.13 or the use of the
proceeds therefrom (including any refusal by the Issuing Bank to honor a demand
for payment under any such Letter of Credit if the documents presented in
connection with such demand do not strictly comply with the terms of such Letter
of Credit), (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property owned or operated by any Loan Party, or
liability under any Environmental Laws related in any way to any Loan Party, or
(iv) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory and regardless of whether any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses are
determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
such Indemnitee. As used in this clause (b), the term "fees, charges and
disbursements of any counsel for any Indemnitee" shall include allocable costs
and expenses of such Indemnitees's in-house legal counsel and staff (to the
extent in substitution for, and not duplicative of, outside counsel and outside
appraisal, audit, environmental and other similar services).

            (c) To the extent permitted by applicable law, the Borrower shall
not assert, and hereby waives, any claim against any Indemnitee, on any theory
of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with, or as a
result of, this Agreement, any other Loan Document, or any agreement or
instrument contemplated hereby or arising out of the activities in connection
herewith or therewith.

            (d) All amounts due under this Section 10.3 shall be payable not
later than ten (10) Business Days after written demand therefor.

            (e) The agreements in this Section 10.3 shall survive the
termination of the Commitments and repayment of all other Obligations.

      Section 10.4. Successors and Assigns.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that (i) the Borrower may not assign or otherwise
transfer any of its rights or obligations

                                       84

<PAGE>

hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and
void) and (ii) no Lender may assign or otherwise transfer its rights or
obligations hereunder except in accordance with this Section 10.4. Nothing in
this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns
permitted hereby, Participants (to the extent provided in paragraph (c) of this
Section 10.4) and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent and the Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

            (b) (i)Any Lender may assign to one or more Eligible Assignees
approved by the Administrative Agent and (so long as no Event of Default is
continuing) the Borrower (which approvals shall not be unreasonably withheld or
delayed) all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans at the time owing to
it); provided that (A) no approval of the Administrative Agent shall be required
for any assignment to an assignee that is a Lender immediately prior to giving
effect to such assignment, (B) each assignee Lender shall provide appropriate
assurances and indemnities to the Issuing Bank as it may reasonably require with
respect to any continuing obligation to purchase participation interests in any
Drawing or other Reimbursement Obligation, (C) except in the case of an
assignment to a Lender or an Affiliate of a Lender or an assignment of the
entire remaining amount of the assigning Lender's Loans and Commitment, the
amount of the Loans and Commitment of the assigning Lender subject to each such
assignment (determined as of the date the Assignment and Assumption with respect
to such assignment is delivered to the Administrative Agent) shall not be less
than $5,000,000 unless each of the Administrative Agent and, so long as no Event
of Default has occurred and is continuing, the Borrower otherwise consents; (D)
each partial assignment shall be made as an assignment of a proportionate part
of all the assigning Lender's rights and obligations under this Agreement; (E)
the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation
fee of $3,500 and any required tax forms; and (F) the assignee, if it shall not
be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire.

                  (ii) Subject to acceptance and recording thereof pursuant to
      paragraph (b)(iv) of this Section 10.4, from and after the effective date
      specified in each Assignment and Assumption the assignee thereunder shall
      be a party hereto and, to the extent of the interest assigned by such
      Assignment and Assumption, have the rights and obligations of a Lender
      under this Agreement, and the assigning Lender thereunder shall, to the
      extent of the interest assigned by such Assignment and Assumption, be
      released from its obligations under this Agreement (and, in the case of an
      Assignment and Assumption covering all of the assigning Lender's rights
      and obligations under this Agreement, such Lender shall cease to be a
      party hereto but shall continue to be entitled to the benefits of Sections
      3.1, 3.3, 3.4 and 10.3). Upon request, the Borrower (at its expense) shall
      execute and deliver a Note to the assignee Lender. Any assignment or
      transfer by a Lender of rights or obligations under this Agreement that
      does not comply with this Section 10.4 shall be treated for purposes of
      this Agreement as a sale by such Lender of a participation in such rights
      and obligations in accordance with paragraph (c) of this Section 10.4.

                                       85

<PAGE>

                  (iii) The Administrative Agent, acting solely for this purpose
      as an agent of the Borrower, shall maintain at one of its offices a copy
      of each Assignment and Assumption delivered to it and a register for the
      recordation of the names and addresses of the Lenders, and the Commitment
      of, and principal amount of the Loans owing to, each Lender pursuant to
      the terms hereof from time to time (the "REGISTER"). The entries in the
      Register shall be conclusive, and the Borrower, the Administrative Agent
      and the Lenders may treat each Person whose name is recorded in the
      Register pursuant to the terms hereof as a Lender hereunder for all
      purposes of this Agreement, notwithstanding notice to the contrary. The
      Register shall be available for inspection by the Borrower and any Lender,
      at any reasonable time and from time to time upon reasonable prior notice.

                  (iv) Upon its receipt of a duly completed Assignment and
      Assumption and required tax forms executed by an assigning Lender and an
      Eligible Assignee, the assignee's completed Administrative Questionnaire
      (unless the assignee shall already be a Lender hereunder) and the
      processing and recordation fee referred to in paragraph (b)(i) of this
      Section 10.4, the Administrative Agent shall accept such Assignment and
      Assumption and record the information contained therein in the Register.
      No assignment shall be effective for purposes of this Agreement unless it
      has been recorded in the Register as provided in this paragraph.

            (c) (i) Any Lender may, without the consent of or notice to the
Borrower or the Administrative Agent, sell participations to one or more banks
or other entities (each, a "PARTICIPANT") in all or a portion of such Lender's
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans owing to it); provided that (A) such Lender's
obligations under this Agreement shall remain unchanged, (B) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (C) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, modification or waiver described in the first proviso to Section
10.1(a) that affects such Participant. Subject to Paragraph (c)(ii) of this
Section 10.4, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 3.1, 3.3 and 3.4 to the same extent as if it were a Lender
and had acquired its interest by assignment pursuant to Paragraph (b) of this
Section 10.4.

                  (ii) A Participant shall not be entitled to receive any
      greater payment under Section 3.1, 3.4 or 3.5 than the applicable Lender
      would have been entitled to receive with respect to the participation sold
      to such Participant. Without limitation of the preceding sentence, (i) a
      Participant that would be a Foreign Lender if it were a Lender shall not
      be entitled to the benefits of Section 3.1 unless the Borrower is notified
      of the participation sold to such Participant and such Participant agrees,
      for the benefit of the Borrower, to comply with Section 3.1(e) as though
      it were a Lender and (ii) a Participant that is a United States resident
      individual shall not be entitled to the benefits

                                       86

<PAGE>

      of Section 3.1 as if it were a Lender unless the Participant agrees to
      comply with Section 3.1(g) as though it were a Lender.

            (d) Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section 10.4 shall not apply to any such pledge
or assignment of a security interest; provided that no such pledge or assignment
of a security interest shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

      Section 10.5. Confidentiality.

      Each of the Administrative Agent and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates' directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential), (b) to the extent requested by any Governmental
Authority, (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (d) to any other party to this Agreement
or any other Loan Document, (e) in connection with the exercise of any remedies
hereunder or under any other Loan Document or any suit, action or proceeding
relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) subject to an agreement containing
provisions substantially the same as those of this Section 10.5, to (i) any
assignee of or Participant in, or any prospective assignee of or Participant in,
any of its rights or obligations under this Agreement or its advisers, or (ii)
any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to the Borrower and its obligations, (g) with
the consent of the Borrower or (h) to the extent such Information becomes
publicly available other than as a result of a breach of this Section 10.5. For
the purposes of this Section, "INFORMATION" means all information received from
the Borrower relating to any Loan Party or its business, other than any such
information that is available to the Administrative Agent or any Lender on a
non-confidential basis from a source other than the Borrower or any of its
Affiliates that is not prohibited from transmitting the information to the
Administrative Agent or such Lender by a contractual or legal obligation. Any
Person required to maintain the confidentiality of Information as provided in
this Section 10.5 shall be considered to have complied with its obligation to do
so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

      Section 10.6. Limitation on Interest.

      Notwithstanding anything to the contrary contained in any Loan Document,
the interest and fees paid or agreed to be paid under the Loan Documents shall
not exceed the maximum rate of non-usurious interest permitted by applicable
Legal Requirement (the "MAXIMUM RATE"). If the Administrative Agent or any
Lender shall receive interest or a fee in an amount that exceeds the Maximum
Rate, the excessive interest or fee shall be applied to the principal of the
outstanding Obligations or, if it exceeds the unpaid principal, refunded to the
Borrower. In determining whether the interest or a fee contracted for, charged,
or received by the

                                       87

<PAGE>

Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to
the extent permitted by applicable Legal Requirement, (a) characterize any
payment that is not principal as an expense, fee, or premium rather than
interest, (b) exclude voluntary prepayments and the effects thereof, and (c)
amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the contemplated term of the Obligations.

      Section 10.7. Right of Setoff.

      If an Event of Default shall have occurred and be continuing, each Lender
and each of its Affiliates is hereby authorized at any time and from time to
time, to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other obligations at any time owing by such Lender or Affiliate to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement held
by such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement and although such obligations may be unmatured;
provided that if any such set off is effected prior to acceleration of the Loans
pursuant to Section 7.2 and all Events of Default are cured prior to any such
acceleration, such set off (other than any portion thereof that has been applied
against matured Obligations) shall be rescinded and the deposits and other
amounts so set off (other than such portion) shall be restored to the Borrower,
without interest, not later than three (3) Business Days after the
Administrative Agent has notified the Lenders in writing that no Event of
Default is continuing or, if the benefit of such set off has been shared by the
Lenders in accordance with Section 2.12, promptly after such Lender receives the
corresponding payments from other Lenders. The rights of each Lender under this
Section 10.7 are in addition to other rights and remedies (including other
rights of setoff) which such Lender may have.

      Section 10.8. Nonliability of Lenders.

      The Borrower acknowledges and agrees that:

            (a) Any inspections of any property of the Borrower made by or
through the Administrative Agent or Lenders are for purposes of administration
of the Loan Documents only, and the Borrower is not entitled to rely upon the
same (whether or not such inspections are at the expense of the Borrower);

            (b) The relationship between the Borrower and the Administrative
Agent and Lenders is, and shall at all times remain, solely that of borrower and
lenders; neither the Administrative Agent nor any Lender shall under any
circumstance be construed to be partners or joint venturers of any Loan Party or
its Affiliates; neither the Administrative Agent nor any Lender shall under any
circumstance be deemed to be in a relationship of confidence or trust or a
fiduciary relationship with any Loan Party or its Affiliates, or to owe any
fiduciary duty to any Loan Party or its Affiliates; neither the Administrative
Agent nor the Lenders undertake or assume any responsibility or duty to any Loan
Party or its Affiliates to select, review, inspect, supervise, pass judgment
upon or inform any such Person of any matter in connection with the operations
of such Person; each Loan Party and its Affiliates shall rely entirely upon
their own judgment with respect to such matters; and any review, inspection,
supervision, exercise of judgment or supply of information undertaken or assumed
by the Administrative Agent or any

                                       88

<PAGE>

Lender in connection with such matters is solely for the protection of the
Administrative Agent and each Lenders and neither any Loan Party nor any other
Person is entitled to rely thereon; and

      Section 10.9. Limitation of Recourse.

      There shall be full recourse to the Borrower and all of its assets and
properties for the liabilities of the Borrower under this Agreement, any Notes
and the other Loan Documents, subject to clauses (i) and (iv) of the following
sentence, in no event shall the Investor or any of their Affiliates (other than
any Loan Party) (collectively, the "NON-RECOURSE PARTIES"), or any officer or
director of the Borrower, be personally liable or obligated for such liabilities
and obligations of the Borrower, except as may be specifically provided in any
other Loan Document to which such Non-Recourse Party is a party. Nothing herein
contained shall limit or be construed to (i) release any Non-Recourse Party from
liability for its fraudulent actions or misappropriation of funds by it or
willful misconduct or for reimbursement of any Distribution made to it in
violation of Section 6.2(f), or from any of its obligations or liabilities under
any agreement executed by such Non-Recourse Party in its individual capacity in
connection with any Loan Document, (ii) limit or impair the exercise of remedies
with respect to any Collateral, (iii) limit the liability of any Person who is a
party to a Loan Document with respect to such liability as may arise by reason
of the terms and conditions of such Loan Document (but subject to any limitation
of liability contained in such Loan Document), or (iv) require the Financing
Parties to indemnify the Non-Recourse Parties for liabilities or claims that may
be independently asserted against them. The provisions of this Section 10.9
shall survive the termination of this Agreement.

      Section 10.10. Integration.

      This Agreement, together with the other Loan Documents, comprises the
complete and integrated agreement of the parties on the subject matter hereof
and thereof and supersedes all prior agreements, written or oral, on such
subject matter. For the avoidance of doubt, each Loan Document (other than the
Original Loan Agreement) entered into prior to the date hereof shall continue to
be, and shall remain, in full force and effect, shall be binding upon the
parties thereto in accordance with their respective terms, and are hereby
ratified and confirmed, except that references in such Loan Documents to the
Original Loan Agreement shall be deemed to be made to this Agreement. In the
event of any conflict between the provisions of this Agreement and those of any
other Loan Document, the provisions of this Agreement shall control; provided
that the inclusion of supplemental rights or remedies in favor of the
Administrative Agent or the Lenders in any other Loan Document shall not be
deemed a conflict with this Agreement. Each Loan Document was drafted with the
joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

      Section 10.11. Survival of Representations and Warranties.

      All representations and warranties made hereunder and in any document,
certificate or statement delivered pursuant hereto or in connection herewith
shall survive the execution and delivery of this Agreement and any Notes.

      Section 10.12. Governing Law.

      This Agreement shall be governed by and construed in accordance with the
law of the State of New York.

      Section 10.13. Submission To Jurisdiction; Waiver of Jury Trial.

            (a) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, solely for purposes of any action or proceeding arising out of
or relating to this Agreement (and not as a general submission to New York law),
or for recognition or enforcement of any judgment, and each of the parties
hereto hereby irrevocably and unconditionally agrees that all claims in respect
of any such action or proceeding may be heard and determined in such New York
State or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that the Administrative Agent or any Lender may otherwise have
to bring any action or proceeding relating to this Agreement against the
Borrower or its properties in the courts of any jurisdiction.

            (b) The Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any court referred to
in paragraph (a) of this Section 10.13. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

            (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 10.2. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

            (d) EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT
IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUR OF OR RELATING
TO ANY LOAN DOCUMENT OR THE TRANSACTION CONTEMPLATED HEREBY OR THEREBY (WHETHER
FOUNDED IN CONTRACT OR TORT OR OTHERWISE). EACH PARTY HERETO ACKNOWLEDGES THAT
IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS PARAGRAPH.

      Section 10.14. Severability.

      If any provision of this Agreement or the other Loan Documents is held to
be illegal, invalid or unenforceable, (a) the legality, validity and
enforceability of the remaining provisions of this Agreement and the other Loan
Documents shall not be affected or impaired thereby and (b) the parties shall
endeavor in good faith negotiations to replace the illegal, invalid or

                                       90

<PAGE>

unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the illegal, invalid or unenforceable
provisions. The invalidity of a provision in a particular jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

      Section 10.15. Headings.

      The table of contents and the headings of Articles, Sections, Exhibits and
Schedules have been included herein for convenience of reference only, are not
part of this Agreement, and shall not be taken into consideration in
interpreting this Agreement.

      Section 10.16. Counterparts.

      This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts, and all of said counterparts
taken together shall be deemed to constitute one and the same instrument. A set
of the copies of this Agreement signed by all the parties shall be maintained by
the Borrower and the Administrative Agent.

      owned by Arrendadora, which had been housed at Atlantic's facility at
      Hobby Airport in Houston. By letter dated September 29, 1999,
      Arrendadora's attorney threatened litigation in this matter if it were not
      resolved.

                             EMPLOYEE BENEFIT PLANS

(a)   A subsidiary of HGC Holdings LLC maintains or contributes to the Pension
      Plan for the Classified Employees of Gasco, Inc.

      Loan Parties contribute to union benefit plans that provide welfare
      benefits to union employees located at Republic Airport and Atlantic City
      Airport.

      Executive sponsors a retiree medical and life insurance plan available to
      certain employees for Atlantic Aviation Corporation. Currently, the plan
      is funded as required to pay benefits and, at December 31, 2004 and 2003,
      the plan had no assets. Executive accounts for postretirement healthcare
      and life insurance benefits in accordance with SFAS No. 106, Employers'
      Accounting for Postretirement Benefits Other Than Pensions. The
      accumulated benefit obligation at December 31, 2004 and 2003, using an
      assumed discount rate of 5.75% and 6%, was approximately $0.7 million and
      $0.8 million, respectively, and the net periodic postretirement benefit
      cost during 2004 and 2003 were $82,000 and $102,000, using an assumed
      discount rate of 6% and 6.75% respectively. The post retirement benefit
      cost was determined using January 1, 2004 and 2003 data. There have been
      no changes in plan provisions during 2004 or 2003. For measurement
      purposes, a 12% annual rate of increase in the per capita cost of covered
      health care benefits was assumed for 2004 and assumed to decrease
      gradually to 5% by 2013 and remain at that level thereafter.

      Executive sponsors a Medicare Supplement Plan that is a premium payment
      plan with six participants.

      The provisions of certain employment contracts provide for limited periods
      during which health care coverage is continued following termination of
      the contracts.

(b)   None
