      account of the Administrative Agent most recently designated by it for
      such purpose by notice to the Term Loan Lenders. Upon satisfaction of the
      applicable conditions set forth in Article IV, the Administrative Agent
      will make such Term Loans available to the Borrower by 2:00 p.m. by wire
      transfer of such funds, in accordance with instructions reasonably
      acceptable to the Administrative Agent provided by the Borrower.

                  (iii) Unless the Administrative Agent shall have been notified
      in writing by any Term Loan Lender prior to the proposed date of any Term
      Loan Borrowing that such Term Loan Lender will not make available to the
      Administrative Agent such Term Loan Lender's share of such Term Loan
      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

                                       2
<PAGE>

      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.

            (c) Limitation on Term Loan Commitments. The Borrower acknowledges
that, as of the Closing Date, there are no Term Loan Commitments with respect to
the second Borrowing of Term Loans, and that such Term Loan Commitments shall
only become available at such time as one or more Eligible Assignees become Term
Lenders party hereto in accordance with Section 10.17. The Borrower further
acknowledges that neither the Lead Arranger nor the Administrative Agent has
made any representation or warranty as to the availability of or prospects for
any such Eligible Assignee becoming a Term Loan Lender. Neither the Lead
Arranger nor the Administrative Agent has any duty or responsibility to solicit
any such Eligible Assignee.

      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 (1) the Revolving Loan Commitment at any given time or (2) the
Borrowing Base as determined on the basis of the most recent monthly operating
report of the Borrower and its Subsidiaries. Within the foregoing limits, and
subject to the other terms and conditions hereof, the Borrower

                                       3
<PAGE>

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 Revolving Loan Lender (with a copy thereof
      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.

Each Revolving Loan Borrowing Request for a Revolving Loan Borrowing consisting
of LIBOR Revolving Loans must be received by the Revolving Loan Lender (with a
copy thereof to 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
Revolving Loan Lender (with a copy thereof to 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.

                  (ii) Upon satisfaction of the applicable conditions set forth
      in Section 4.3, the Revolving Loan Lender shall, not later than 2:00 p.m.,
      New York City time, on the borrowing date specified in such Revolving Loan
      Borrowing Request, make the amount of its Revolving Loan available to the
      Borrower by wire transfer of such funds in accordance with instructions
      reasonably acceptable to the Revolving Loan Lender provided by the
      Borrower. Notwithstanding the foregoing, if, at the time of the Borrowing
      of such Revolving Loan, the Administrative Agent shall have notified the
      Revolving Loan Lender in writing, at least one (1) Business Day prior to
      the date of such Borrowing, that a Default or Event of Default has
      occurred and is continuing and that

                                       4
<PAGE>

      Revolving Loans may not be made while such Default or Event of Default is
      continuing (which notice will be given at the request of the Required
      Lenders), the Revolving Loan Lender shall not advance such Revolving
      Loans. 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 4.3 have been
      satisfied.

            (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:

                  (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 Revolving
Loan Lender (with a copy thereof to 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 (one (1) Business Day before the date of conversion, in the
case of a conversion to a Base Rate Revolving Loan).

            (d) Interest for Account of Revolving Loan Lender. Each Revolving
Loan shall bear interest in accordance with Section 2.3. The Revolving Loan
Lender shall be responsible for invoicing the Borrower for interest on the
Revolving Loans. Interest on each Revolving Loan shall be solely for the account
of the Revolving Loan Lender. The Borrower shall make all payments of principal
and interest in respect of the Revolving Loans directly to the Revolving Loan
Lender.

            (e) Extension of Revolving Loan Commitment. The Borrower may, by
written notice to the Revolving Loan Lender no later than 90 days prior to the
Revolving Loan Commitment Termination Date then in effect (the "Existing
Revolving Loan Commitment Termination Date"), request that the Revolving Loan
Lender extend the Revolving Loan Commitment Termination Date to the date
proposed by the Borrower in such notice. If the Revolving Loan Lender so agrees
in writing, which shall be in its sole and absolute discretion, the Existing
Revolving Loan Commitment Termination Date shall be extended (effective as of
the Existing Revolving Loan Commitment Termination Date) to the date specified
in such notice

                                       5
<PAGE>

as confirmed by the Revolving Loan Lender in its written confirmation. The
Revolving Loan Lender will notify the Borrower in writing of its decision no
later than 60 days prior to the Existing Revolving Loan Commitment Termination
Date. If any such extension of the Existing Revolving Loan Commitment
Termination Date shall not become effective, then the Revolving Loan Commitment
shall reduce to zero on the Existing Revolving Loan Commitment Termination Date,
and the Revolving Loan Commitment Termination Date shall remain the Existing
Revolving Loan Commitment Termination Date. If the Revolving Loan Lender shall
not have provided notice of its extension of the Existing Revolving Loan
Commitment Termination Date 60 days prior thereto, the Revolving Loan Lender
shall be deemed to have declined to extend the Existing Revolving Loan
Commitment Termination Date.

      Section 2.3 Interest.

            (a) Each Term 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 LIBOR Revolving Loan shall bear interest at the LIBOR Market Index
Rate plus the Applicable Margin, and 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 (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided in the above paragraph (a) of
this Section, or (ii) in the case of any other amount, 2% 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; provided that the applicable Base
Rate or LIBOR with respect to any Revolving Loan shall be determined by the
Revolving Loan Lender, and each 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 a Term Loan in the relevant Borrowing
Request and shall select each subsequent Interest Period for such 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.

                                       6
<PAGE>

            (b) The Term Loans shall at any given time be subject to a single
Interest Period; provided that (i) the initial Interest Period with respect to
the second Borrowing of the Term Loans will commence on the date of such
Borrowing and end on the same day as the current Interest Period for the Term
Loans previously advanced and (ii) if the Borrower elects an Interest Period for
the Term Loans that ends after the next succeeding Repayment Date or Cash Sweep
Date, the Borrower may elect a separate Interest Period ending on such Repayment
Date or Cash Sweep Date for any portion of the Term Loans to be repaid or
projected to be repaid on such date.

            (c) No Interest Period shall extend beyond the Maturity Date.

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

            (e) If an Event of Default has occurred and is continuing on the day
on which interest is due and payable for any LIBOR Revolving Loan, then unless
repaid, such Loan(s) shall automatically convert to Base Rate Revolving Loan(s)
on such day.

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

      Section 2.5 Repayment of Loans.

            (a) Term Loans.

                  (i) Subject to paragraph (ii) below, so long as any portion of
      the Class A Loans remains outstanding, the Borrower shall repay to the
      Administrative Agent for the account of the Class A Lenders on each
      Repayment Date a portion of the Class A Loans equal in amount to the
      Required Class A Loan Repayment Amount.

                  (ii) Notwithstanding the foregoing, if the funds on deposit in
      the Accounts and available for the repayment of Class A Loans are
      insufficient as of any Repayment Date to pay the Required Class A Loan
      Repayment Amount, the Borrower may, so long as no Event of Default has
      occurred and is continuing as of such Repayment Date, defer repayment of a
      portion thereof equal to the lesser of (i) such deficiency or (ii) the
      Accelerated Class A Loan Amortization Amount.

                  (iii) 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.

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

                                       7
<PAGE>

            (b) Revolving Loans. The Borrower shall repay to the Revolving Loan
Lender on the Revolving Loan Commitment Termination Date the aggregate principal
amount of the Revolving Loans outstanding on such date.

      Section 2.6 Use of Proceeds of Loans.

            (a) Initial Borrowing of Term Loans. The proceeds of the initial
Borrowing of Term Loans shall be used solely (i) to refinance a portion of the
Purchase Price (as defined in the Executive Air Stock Purchase Agreement),
including transaction and bridge financing costs; (ii) to pay fees payable on
the date of the initial Term Loan Borrowing to the Lead Arrangers and the
Administrative Agent; (iii) to make payment of the Debt Service Reserve Required
Balance into the Debt Service Reserve Account as required hereunder; (iv) 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 (v) to pay
other reasonable costs and expenses incurred by the Borrower in connection with
the closing of the Loans.

            (b) The proceeds of the second Borrowing of Term Loans shall be used
solely (i) to finance a portion of the purchase price with respect to the
acquisition of GAH, including transaction costs and repayment of existing
Indebtedness; (ii) to pay or reimburse the Borrower for costs and expenses
payable by the Borrower pursuant hereto in connection with such Borrowing; (iii)
to pay the increased amount of the Debt Service Reserve Required Balance as a
result of such Borrowing into the Debt Service Reserve Account, and (iv) to pay
other reasonable costs and expenses incurred by the Borrower in connection with
such Borrowing.

            (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, but excluding Expansion Capital Expenditures); 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 unless the Issuing
Bank is satisfied that sufficient funds will be available to permit repayment of
Drawings under any Letter of Credit outstanding as of the date of termination.
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

                                       8
<PAGE>

in accordance with their respective Class A Commitments and Class B 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 initial Borrowing of Term Loans have not been borrowed on
or before December 31, 2004, 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.

            (c) 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) and 2.8(c)(vi)
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. Any
partial prepayment of Class A Loans shall be applied to prepay installments of
Required Class A Loan Repayment Amounts in the reverse order of maturity. 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 or
      LIBOR Revolving Loans, and (B) not later than 11:00 a.m. on the proposed
      date of prepayment of Base Rate 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.

                                       9
<PAGE>

                  (ii) Promptly following receipt of any such notice of
      voluntary prepayment, the Administrative Agent shall advise the applicable
      Lenders of the contents thereof. With respect to any proposed prepayment
      of Term Loans, the Required Class B Lenders may, not later than three (3)
      Business Days after the giving of such notice, elect by written notice to
      the Administrative Agent that such prepayment of Term Loans shall be
      applied in accordance with clause (B) of Section 2.8(b)(iii).

                  (iii) Optional prepayments of the Term Loans made pursuant to
      this Section 2.8(b) shall be applied (A) to prepay the Class A Loans until
      paid in full and thereafter to prepay the Class B Loans or (B) if the
      Required Class B Lenders shall so elect in accordance with Section
      2.8(b)(ii), pro rata to the Term Loans outstanding.

                  (iv) 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 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) prepay the Revolving
      Loans to the extent Revolving Loans are then outstanding, and (C)
      otherwise, Cash Collateralize the outstanding L/C 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 (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, any Loan Party
      issues or incurs any Indebtedness for borrowed money, including
      Indebtedness evidenced by notes, bonds, debentures or other similar
      instruments, but excluding Permitted Indebtedness, the

                                       10
<PAGE>

      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) prepay the Revolving Loans to the extent Revolving Loans are
      then outstanding, and (C) otherwise, Cash Collateralize the outstanding
      L/C 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, any Loan Party
      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 funding of Expansion Capital Expenditures), 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) prepay the Revolving Loans to the extent Revolving Loans are
      then outstanding, and (C) otherwise, Cash Collateralize the outstanding
      L/C 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 a Loan Party of any Net Insurance Proceeds 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) prepay the Revolving Loans to the extent Revolving Loans are
      then outstanding, and (C) otherwise, Cash Collateralize the outstanding
      L/C 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 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 it receives such proceeds that it or another 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 Borrower 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 the Borrower 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 on or before September 30, 2005, the Debt Service
      Coverage Ratio as of the end of a fiscal quarter of the Borrower is 1.30
      to 1.00 or lower for at least two (2) consecutive fiscal quarters, the
      monies then on deposit in the Special Reserve Account (inclusive of monies
      transferred to the Special Reserve Account in respect of the

                                       11
<PAGE>

      last such fiscal quarter) shall be applied to prepay the Loans. All
      prepayments of the Loans then outstanding pursuant to this paragraph (v)
      shall be applied, first, to prepay Class A Loans in inverse order of
      maturity until the Class A Loans are prepaid in full, second, to prepay
      Class B Loans until the Class B Loans are prepaid in full, and thereafter,
      to prepay Revolving Loans until the Revolving Loans are prepaid in full.

                  (vi) On each Cash Sweep Date (or such later date not exceeding
      30 days thereafter as the Applicable Cash Sweep Percentage as of such Cash
      Sweep Date has been determined), the Applicable Cash Sweep Percentage of
      Excess Cash Flow as of such Cash Sweep Date shall be applied to prepay the
      Loans. All prepayments of the Loans then outstanding pursuant to this
      paragraph (vi) shall be applied, first, to prepay Class A Loans in inverse
      order of maturity until the Class A Loans are prepaid in full, second, to
      prepay Class B Loans until the Class B Loans are prepaid in full, and
      thereafter, to prepay Revolving Loans until the Revolving Loans are
      prepaid in full.

                  (vii) If, as a result of the making of any prepayment required
      to be made pursuant to clauses (i) through (vi) of this Section 2.8(c),
      the Borrower would incur Hedging Termination Obligations or costs pursuant
      to Section 3.5, upon the request of the Borrower made prior to the due
      date thereof, the amount of such prepayment may be held in the
      Concentration Account until the end of the applicable Interest Period, at
      which time such prepayment shall be made.

      Section 2.9 Fees.

            (a) Commitment Fees. The Borrower agrees to pay (i) to the
Administrative Agent for the account of each Term Lender a commitment fee equal
to 0.50% per annum on the daily amount of the Available Term Loan Commitment of
such Term Lender during the period from and including the Closing Date to but
excluding the last day of the Term Loan Commitment Period, and (ii) to the
Revolving 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 each
year, commencing on the first of such dates to occur after the Closing Date, 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) Upfront Revolving Credit Fee. The Borrower agrees to pay to the
Revolving Loan Lender for its own account an upfront fee equal to 0.75% of the
total amount of the Revolving Loan Commitment, payable on the Initial
Disbursement Date.

            (c) Letter of Credit Fees. The Borrower shall pay to the Revolving
Loan Lender a letter of credit fee for each Letter of Credit 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

                                       12
<PAGE>

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, and on the Letter of Credit Expiration Date.

            (d) 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.

            (e) Other Fees. The Borrower agrees to pay to the Lead Arranger, 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.

            (f) 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.

      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

                                       13
<PAGE>

Administrative Agent (account number 400949687) at JP Morgan Chase Bank (ABA
number 0210000210) or such other account as may hereafter be designated by the
Administrative Agent in writing, except that payments in respect of the
Revolving Loans and the Letters of Credit (including any fees relating thereto)
shall be made to the Revolving Loan Lender or the Issuing Bank, as applicable.
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.

            (d) The Revolving Loan Lender agrees that it will promptly notify
the Administrative Agent of any defaults in the payment of principal, interest
and fees required to be paid to the Revolving Loan Lender for its own account
pursuant to this Agreement.

      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
Class A Loans, Class B 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 Class A Loans,
Class B 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 Class
A Loans, Class B 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 of this paragraph
shall apply). The Borrower consents to the foregoing and agrees, to the extent
it may effectively do so

                                       14
<PAGE>

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 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 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) no 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 shall be in a form reasonably acceptable to the
Issuing Bank. The Issuing Bank and the Borrower hereby agree that the existing
letters of credit described under the subheading "Letters of Credit" on Schedule
6.2(a) shall for purposes of this Agreement be deemed to be Letters of Credit
issued by the Issuing Bank under the Letter of Credit Facility, and further, the
Issuing Bank shall be deemed to have sold and transferred to the Revolving Loan
Lender a 100% participation in each such Letter of Credit in accordance with
clause (c) of this Section 2.13.

            (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), 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), 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

                                       15
<PAGE>

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 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. 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

                                       16
<PAGE>

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 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) 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) 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, 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

                                       17
<PAGE>

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 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, and costs and expenses
of the Administrative Agent. The obligation of the Lenders under this Section
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, in the case of a LIBOR Revolving
Loan, the LIBOR Market Index Rate, or (b)(i)the Administrative Agent is advised
by the Required Lenders that LIBOR determined or to be determined for such
Interest Period will not adequately and fairly reflect the cost to such Lenders
of making or maintaining such Loans for such Interest Period, or (ii) the
Revolving Loan Lender determines that the LIBOR Market Index Rate will not
adequately and fairly reflect the cost to the Revolving Loan Lender of making or
maintaining such Loans, 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

                                       18
<PAGE>

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, 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 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

                                       19
<PAGE>

                  (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;

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 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 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 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 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), 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

                                       21
<PAGE>

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 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 3 shall survive
termination of the Commitments and the payment in full of all Obligations.

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

plan which would result in the incurrence by any Loan Party 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 any Loan Party or any ERISA Affiliate is legally valid and
binding and in full force and effect. Except as set forth on Schedule 5.13, as

Loan Parties and the ERISA Affiliates has been notified that any Multiemployer

Governmental Rule limiting its ability to incur Indebtedness.

      Section 5.15 Patent and Other Rights.

      The Loan Parties own, license or otherwise have the full right to use,
under validly existing agreements, all material patents, licenses, trademarks,
trade names, trade secrets, service marks, copyrights and all rights with
respect thereto, which are required to conduct their businesses as now

Effect. Each of the patents, trademarks, trade names, service marks and
copyrights owned by any Loan Party which is registered with any Governmental
Authority is set forth on Schedule 5.15. The Loan Parties conduct their
respective businesses without infringement or, to the best of the Borrower's

                                       37
<PAGE>

Adverse Effect. There is no infringement or, to the best of the Borrower's

intellectual property right of any of the Loan Parties.

Party is a party, and there are no strikes, lockouts, work stoppages or

      Section 5.21 Contracts.

            (a) Schedule 5.21 lists all of the following contracts ("Contracts")

material provision of any such FBO Lease, including any minimum service
requirements under any FBO Lease and no event has occurred that with the passage
of time or the giving of notice or both

                                       39
<PAGE>

would constitute a default by the Borrower or any Subsidiary or, to the
Borrower's knowledge, any other party under any material provision thereof
entitling the termination of such FBO Lease.

            (c) Except as disclosed in Schedule 5.21, no material supplier to or
landlord of the Borrower or any of its Subsidiaries, including any party to the
FBO Leases, or any Governmental Authority has taken, and neither the Borrower
nor any of its Subsidiaries have received any written notice that, any material
supplier to or landlord of the Borrower or any of its Subsidiaries, including
any party to any of the FBO Leases, or any Governmental Authority contemplates
taking, any steps to terminate the business relationship of the Borrower or any
of its Subsidiaries with such supplier or landlord, including any party to the
FBO Leases, which would reasonably be expected to have a Material Adverse
Effect.

            (d) None of the Loan Parties nor any of their Properties are subject
to any Contractual Obligation which is reasonably likely to have a Material
Adverse Effect.

      Section 5.22 No Material Adverse Effect.

are true, complete and correct in all material respects, do not contain any
untrue statement of a material fact and do not omit to state any material fact
necessary to make the statements therein, in light of the circumstances under

Documents, the transactions contemplated thereby and the Acquisitions have been
prepared on a basis consistent with the historical financial statements

indemnify the Administrative Agent and the Lenders against any such claims for
brokerage fees or commissions and to pay all expenses including, without
limitation, reasonable attorney's fees

material agreement or contract with any Affiliate of such Person except upon
terms at least as favorable to such Loan Party as an arms-length transaction
with unaffiliated Persons, based on the totality of the circumstances. None of
the Loan Parties is a party to or is bound by any Contractual Obligation or is
subject to any restriction under its respective charter or formation documents,
which could reasonably be expected to have a Material Adverse Effect.

<PAGE>

                  (iii) 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

                  (iv) 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 the Collateral
      Agent as lender's loss payee;

provided that if any Loan Party shall fail to maintain insurance in accordance
with this Section 6.1(e), or if any Loan Party 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 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) provide for at
least thirty (30) days' prior written notice to each insured and each loss payee
named therein of the date on which such policies shall terminate by lapse of
time if not renewed, (iii) 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, (iv) insure the Collateral Agent and
any other additional insured or loss payee regardless of any breach or violation
by the Loan Parties or any other Person of any warranties, declarations, or
conditions contained in the policies related to such insurance, (v) 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 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, (vi) 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, (vii)
provide that no Person other than the Loan Parties shall have any liability for
any premiums with respect thereto, and (viii) 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 the insurance policies provided or obtained by any Loan Party
(whether or not required to be carried by the Lenders under the Loan Documents),
including any property and business interruption policies, but excluding
coverage for workers' compensation, employees'

                                       45
<PAGE>

liability and general liability, shall be paid by the respective insurers
directly to the Operating Account held by such Loan Party.

shall promptly pay and discharge 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 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. Each of the Loan Parties shall (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

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

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) 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.
Each Loan Party shall 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.

            (j) Additional Collateral. If at any time from and after the Closing
Date any Loan Party 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

                                       46
<PAGE>

(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 an FBO Lease, 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 Agent for the benefit of the Secured Parties 100% of the Equity
Securities of each Person which becomes a Subsidiary and execute and deliver all

      done as of the date of such certificate, (iv) the amount of net proceeds
      with respect to the Event of Loss remaining in the Concentration Account

      Any Event of Default referred to in Section 7.1(n), (o) or (p) affecting
one or more Eligible FBOs 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 Default occurred multiplied by (ii) the
Proportional EBITDA Contribution of such Eligible FBO(s), whereupon the Loan
Party or Loan Parties 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 Eligible FBO only if the Proportional EBITDA
Contribution of such Eligible FBO, when added to the Proportional EBITDA
Contribution of any other Eligible 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 Investors to the Borrower, or a combination thereof. For
the avoidance of doubt, the cure right permitted by this paragraph shall be
available with respect to the Eligible FBOs only, and may not be exercised more

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 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(h) or (i) 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

                                       63
<PAGE>

Issuing Bank in respect of any Drawing under a Letter of Credit issued 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 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 Revolving Loan Commitment Termination 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 irrevocably 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 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

                                       65
<PAGE>

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 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 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 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

                                       67
<PAGE>

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 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'
notice to the Lenders. If the Administrative Agent resigns under this Agreement,
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 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
hereunder as Administrative Agent, the provisions of this Article IX 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, the retiring

                                       68
<PAGE>

Administrative Agent's resignation 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.

                                   ARTICLE IX

                              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 Lender 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 Lender 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 Lender 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 Agent to seek a lifting of the automatic stay or any other stay
in any Bankruptcy Proceeding so as to permit an acceleration of all of the
amounts outstanding under the Loan Documents pursuant to Section 7.2(a), (iii)
early termination is permitted in accordance with the terms of such Lender
Hedging Agreement by the Hedging Bank in the event it becomes unlawful for such
Hedging Bank to perform any absolute or contingent obligation under such Lender
Hedging Agreement, (iv) early termination is permitted in accordance with the
terms of such Lender Hedging Agreement upon the occurrence of a tax event or tax
event upon merger, (v) the Administrative Agent has requested such termination
in accordance with Section 9.3, or (vi) the Loans are repaid in full.

      Section 9.3 Involuntary Termination or Reduction.

            (a) If 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), each Hedging Bank agrees that, at the written request of the
Administrative Agent (acting at the direction of the Required Lenders), such
Hedging Bank shall exercise its rights to terminate all hedging transactions
under each Lender Hedging Agreement to which it is a party.

            (b) If the aggregate notional amounts hedged under the Lender
Hedging Agreements exceed by more than ten percent (10%) the aggregate principal
amount of the Loans for a period of more than sixty days, the Administrative
Agent (acting at the direction of the Required Lenders) may, by notice to the
Hedging Banks and the Borrower, require that the amounts hedged under the Lender
Hedging Agreements be reduced (allocated ratably among the Lender Hedging
Agreements according to the respective amounts hedged thereunder) to a level
equal to no more than 110% and no less than 100% of the Loans outstanding.

      Section 9.4 Agreement to be Bound by Loan Documents; Benefit of Lien of
Security Documents.

      By entering into a Lender Hedging Agreement entitling it to the benefits
of the Loan Documents, each Hedging Bank shall be deemed to have agreed to be
bound by the provisions set forth in this Agreement and the Collateral Agency
Agreement applicable to Hedging Banks and Financing Parties. So long as the
terms thereof are in compliance with this Agreement, each Lender Hedging
Agreement shall be secured by the Liens created by the Security Documents on a
pari passu basis.

                                  MISCELLANEOUS

      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 the 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

                                       70
<PAGE>

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 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 its 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 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(f) or Section 4.2(g) 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 Initial Disbursement Date or Second Disbursement
Date, as applicable, 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,
and then such waiver or consent shall be effective only in the specific instance
and

                                       71
<PAGE>

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.

other purpose.

            (d) Any party hereto may change its address or telecopy number for

      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,

syndication of the credit facilities provided for herein, and administration of
the transactions contemplated hereby and thereby, (ii) all reasonable

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
(including any indemnity payment by the Administrative Agent to Wachovia Bank,

consummation of the transactions contemplated thereby, (ii) any Commitment, Loan
or Letter of Credit or the use of the proceeds therefrom (including any refusal
by the Issuing Bank to honor a demand for payment under a 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.

                                       74
<PAGE>

            (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 shall be payable not later
than ten Business Days after written demand therefor.

            (e) The agreements in this Section shall survive the termination of

      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 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. 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) 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

                                       75
<PAGE>

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, 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.

                  (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, 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

                                       76
<PAGE>

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, 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.

                  (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 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 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, 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. 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

                                       77
<PAGE>

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 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
Borrower. In determining whether the interest or a fee contracted for, charged,
or received by the 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 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:

                                       78
<PAGE>

            (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 Borrower);

            (b) The relationship between the Borrower and the Administrative
Agent and Lenders is, and shall at all times remain, solely that of borrowers
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 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 Investors or any of their Affiliates (other than
any Loan Party) (collectively, the "Non-Recourse Parties"), or any officer,
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. In the event of any conflict between

                                       79
<PAGE>

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. 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.

                                       80
<PAGE>

            (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
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.

      Section 10.17 Joinder Agreement and Other Agreements

            (a) Upon the execution and delivery after the date hereof by an
Eligible Assignee, the Borrower, each Lender and the Administrative Agent of an
agreement in the form of Exhibit H attached hereto, such Person shall become a
Term Loan Lender hereunder with the same force and effect as if originally named
as a Term Loan Lender hereunder; provided that (i) each such new Lender (which
may include Macquarie Bank Limited so long as its total Commitments (including
its existing Commitments) do not exceed 40% of the aggregate Commitments of all
Lenders) shall be approved by the Administrative Agent and the Borrower, such
approval not to be unreasonably withheld; (ii) the total Commitments of such new
Lender or Lenders shall consist of Term Loan Commitments sufficient, together
with additional equity contributions by the Investors, to allow (x) HSH Nordbank
AG to reach a facility underwriting commitment of $65,000,000 (or such greater
amount as HSH Nordbank AG may agree in its sole discretion) and (y) Macquarie
Bank Limited to reach a facility underwriting commitment of $40,000,000 (or

                                       81
<PAGE>

such greater amount (not to exceed 40% of the aggregate Commitments of all
Lenders) as Macquarie Bank Limited may agree in its sole discretion), in each
case after giving effect to the second Disbursement Date for Term Loans and any
assignments of Loan and Commitments by HSH Nordbank AG and Macquarie Bank
Limited after the Closing Date; (iii) such new Term Loan Commitments shall be
allocated between the Class A Commitments and Class B Commitments in the same
proportions as the respective Class A Commitments and Class B Commitments of the
Lenders party hereto as of the Closing Date; and (iv) each such new Lender shall
concurrently enter into an Assignment and Assumption with each of HSH Nordbank
AG and Macquarie Bank Limited agreeing to purchase and assume its Pro Rata Share
of the Term Loans advanced on the Initial Disbursement Date and shall pay the
purchase price payments thereunder.

            (b) Upon the execution and delivery of the Joinder Agreement(s) in
accordance with this Section, (i) a schedule in substantially the form of
Schedule 2.1 attached to the Joinder Agreement(s) that has been properly revised
and completed to reflect the new Commitments and Pro Rata Shares shall supersede
and replace Schedule 2.1 hereto, and the Commitments and Pro Rata Shares of each
Lender shall be as set forth in such revised Schedule 2.1, and (ii) a schedule
shall be prepared by the Administrative Agent to reflect the required
amortization of Class A Loans based on the new Commitments, which schedule shall
be attached to the Joinder Agreement(s), and shall supersede and replace
Schedule 2.5 hereto, and the required amortization of Class A Loans shall be as
set forth in such revised Schedule 2.5.

            (c) Notwithstanding Section 6.2(c), if the Borrower determines that
it will not be able to satisfy the applicable conditions precedent to the
Borrowing of Term Loans to finance the General Aviation Acquisition, the
Borrower shall have the right to assign either (x) its rights and obligations
under the GAH Purchase Agreement and any related rights or agreements or (y) all
property, assets and rights acquired under the GAH Purchase Agreement if such
transaction has closed, to an Affiliate of the Investors, which Affiliate shall
not be a Subsidiary of the Borrower or a Loan Party.

                      TERMS OF PERMITTED SUBORDINATED DEBT

      Permitted Subordinated Debt shall be issued pursuant to, or evidenced by,
an instrument containing provisions for the subordination of such Permitted
Subordinated Debt to all Obligations, substantially as follows (without
limitation as to further, not inconsistent, provisions if so desired).

      All capitalized terms used in this Exhibit E but not defined herein shall
have the meanings ascribed to such terms in Appendix A to the Loan Agreement.

SUBORDINATION OF PERMITTED SUBORDINATED DEBT

General.

      Notwithstanding any provision of this agreement to the contrary, the
Borrower and the holder of the Permitted Subordinated Debt, for themselves and
for all present and future holders of such Permitted Subordinated Debt, hereby
covenant and agree that the Permitted Subordinated Debt shall be and are hereby
expressly made subordinate and junior in right of payment to the prior payment
(in cash or cash equivalents) and performance in full of all Obligations to the
extent and in the manner provided below.

Waiver.

      The holder of the Permitted Subordinated Debt (or any instrument
evidencing the same) by acceptance hereof waives any and all notice of the
creation or accrual of any such Obligations and notice of proof of reliance upon
these subordination provisions by any holder of Obligations and hereby assents
to any renewal, extension or postponement of the time of payment of Obligations
or any other indulgence with respect thereto, to any increase in the amount of
Obligations, and to any substitution, exchange or release of collateral
therefor; and any such Obligations shall conclusively be deemed to have been
created, contracted or incurred in reliance upon these subordination provisions
and all dealings between the Borrower and any holder of Obligations so arising
shall be deemed to have been consummated in reliance upon these subordination
provisions.

Effects of Certain Defaults in Respect of Obligations.

      If the Borrower or any other Loan Party shall default in the payment of
any principal of or interest on or other amount with respect to the Obligations
when the same becomes due and payable, whether at maturity or at a date fixed
for prepayment or by declaration or otherwise, or if any other default or event
of default with respect to any such Obligations shall have occurred (each of the
foregoing a "Default"), and unless and until such Default shall have been
remedied or waived or shall have ceased to exist, no direct or indirect payment
by the Borrower from any

                                    Exh. E-1
<PAGE>

source whatsoever shall be made on account of the principal of, or premium, if
any, or interest on or other amount with respect to, the Permitted Subordinated
Debt.

Limitation on Payments and Demand for Payments.

      For so long as any Obligations are outstanding, (i) the Borrower shall
not, directly or indirectly, make, or permit any of its Affiliates to make, any
payment of principal or interest on account of the Permitted Subordinated Debt,
except for payments from amounts that the Borrower would be permitted to pay as
a Distribution in accordance with Section 6.2(f) of the Loan Agreement and (ii)
without the prior written consent of the Required Lenders, the holder of the
Permitted Subordinated Obligations shall not demand, sue for, retain, or accept
from the Borrower or any other Person any payment of principal or interest on
account of such Permitted Subordinated Debt, except for payments from amounts
that the Borrower would be permitted to pay as a Distribution in accordance with
Section 6.2(f) of the Loan Agreement.

Limitation on Acceleration.

      For so long as any Obligations are outstanding, the Permitted Subordinated
Debt may not be declared to be due and payable before its stated maturity unless
all Obligations have become due and payable, whether automatically or by
declaration, before its stated maturity and such declaration has not been
rescinded.

Insolvency, Etc.

      (a) In the event of any liquidation, reorganization, dissolution, winding
up or composition or readjustment of the Borrower or its respective interests
(whether voluntary or involuntary, or in bankruptcy, insolvency, reorganization,
liquidation, receivership proceedings, or upon a general assignment for the
benefit of the Borrower's creditors or any other marshalling of the assets and
liabilities of the Borrower, or otherwise), all Obligations (including any claim
for interest thereon accruing at the contract rate after the commencement of any
such proceedings and any claim for additional interest that would have accrued
thereon but for the commencement of such proceedings, whether or not, in either
case, such claim shall be enforceable in such proceedings) shall first be paid
in full in cash or cash equivalents before any direct or indirect payment or
distribution, whether in cash or cash equivalents, securities or other property,
is made in respect of the Permitted Subordinated Debt, and any cash, securities
or other property, which would otherwise (but for these subordination
provisions) be payable or deliverable in respect of the Permitted Subordinated
Debt directly or indirectly by the Borrower from any source whatsoever shall be
paid or delivered directly to the holders of Obligations until all Obligations
(including claims for interest and additional interest as aforesaid) shall have
been paid in full in cash or cash equivalents; provided that the holders of the
Permitted Subordinated Debt may receive and retain (x) shares of equity
securities of the Borrower and (y) debt securities of the Borrower, the payment
of which is subordinated to the full and final payment of all Obligations on the
same basis as the Permitted Subordinated Debt.

      (b) The holder of Permitted Subordinated Debt shall not commence or join
with any other creditor or creditors of the Borrower in commencing any
bankruptcy, insolvency,

                                    Exh. E-2
<PAGE>

reorganization, liquidation or receivership proceedings against the Borrower. At
any general meeting of creditors of the Borrower in the event of any
liquidation, reorganization, dissolution, winding up or composition or
readjustment of the Borrower or its interests (whether voluntary or involuntary,
or in bankruptcy, insolvency, reorganization, liquidation, receivership
proceedings, or upon a general assignment for the benefit of the Borrower's
creditors or any other marshalling of the assets and liabilities of the
Borrower, or otherwise), if all Obligations have not been paid in full at such
time, the Required Lenders (or any authorized agent thereof) are hereby
irrevocably authorized at any such meeting or in any such proceeding:

            (1)   to enforce claims comprising Permitted Subordinated Debt in
                  the name of the holder of such Permitted Subordinated Debt, by
                  proof of debt, proof of claim, suit or otherwise; and

            (2)   to collect any assets of the Borrower distributed, divided or
                  applied by way of dividend or payment, or such securities
                  issued, on account of Permitted Subordinated Debt, and apply
                  the same, or the proceeds of any realization upon the same
                  that the Required Lenders in their discretion elects to
                  effect, to the Obligations until all Obligations shall have
                  been paid in full.

      (c) The Borrower and holder of the Permitted Subordinated Debt each hereby
(i) irrevocably authorizes and empowers the Required Lenders, under the
circumstances set forth in the above paragraph, to demand, sue for, collect and
receive every such payment or distribution referred to in such paragraph (b) and
give acquittance therefor, and execute, verify, deliver and file any claims or
proofs of claim (to the extent not properly filed by the holder of the Permitted
Subordinated Debt within two weeks prior to the due date for any such filing),
assignments or other instruments which any holder of the Obligations may at any
time reasonably require in order to provide and realize upon any rights or
claims pertaining to the Permitted Subordinated Debt in any statutory or
non-statutory proceeding in accordance with these subordination provisions, and
take such other actions, on behalf of the holders of the Obligations or
otherwise, as the Required Lenders may deem necessary or advisable for the
enforcement of the subordination provisions hereto and (ii) appoints any Person
designated for such purpose by the Required Lenders as its attorney-in-fact for
all such purposes.

Turnover of Payments.

      If (i) any payment or distribution shall be collected or received by the
holder of the Permitted Subordinated Debt in contravention of the terms hereto
and prior to the payment in full in cash or cash equivalents of all Obligations
at the time outstanding and (ii) any holder of such Obligations (or any
authorized agent thereof) shall have notified the holder of the Permitted
Subordinated Debt of the facts by reason of which such collection or receipt so
contravenes the subordination provisions hereto, the holder of the Permitted
Subordinated Debt will deliver such payment or distribution, to the extent
necessary to pay all such Obligations in full in cash or cash equivalents, to
the Collateral Agent, for the benefit of the holders of the Obligations, in the
form received, and until so delivered, the same shall be held by the holder of
the Permitted Subordinated Debt in trust for the holders of the Obligations and
shall not be commingled with other funds or property of the holder of the
Permitted Subordinated Debt.

No Prejudice or Impairment.

      No present or future holder of any Obligations shall be prejudiced in the
right to enforce subordination of the Permitted Subordinated Debt by any act or
failure to act on the part of the Borrower. Nothing contained herein shall
impair, as between the Borrower and the holder of the Permitted Subordinated
Debt, the obligation of the Borrower to pay to the holder hereof the principal
hereof and premium, if any, and interest hereon as and when the same shall
become due and payable in accordance with the terms hereof, or, except as
provided herein, prevent the holder of the Permitted Subordinated Debt from
exercising all rights, powers and remedies otherwise permitted by applicable law
or thereunder upon the happening of an event of default in respect of the
Permitted Subordinated Debt, all subject to the rights of the holders of
Obligations as provided in this section to receive cash, securities or other
property otherwise payable or deliverable to the holder of the Permitted
Subordinated Debt directly or indirectly by the Borrower from any source
whatsoever.

of such subrogation, no payment or distribution received by the holders of
Obligations of cash, securities, or other property to which the holder of the
Permitted Subordinated Debt would have been entitled except for this Section
shall, as between the Borrower and its creditors other than the holders of

on the other hand, be deemed to be a payment or distribution by the Borrower on
account of Obligations.

No Assignment.

      The holder of the Permitted Subordinated Debt may not assign all or a
portion of such Permitted Subordinated Debt without the prior written consent of
the Required Lenders and only upon the execution and delivery to the Required

hereto, in form and substance satisfactory to the Required Lenders.

holders of the Obligations without the prior written consent thereto of the
Required Lenders.

      (b) The Borrower and the holder of the Permitted Subordinated Debt shall
execute and deliver to the Required Lenders such further instruments and shall
take such further action as the

                            Form of Control Agreement

                                CONTROL AGREEMENT

      This Control Agreement, dated as of [________], 200[__] (this
"Agreement"), among NORTH AMERICA CAPITAL HOLDING COMPANY (the "Borrower"), THE
BANK OF NEW YORK, as Collateral Agent (the "Collateral Agent") for the benefit
of the Secured Parties (as defined in the Loan Agreement referred to below), and
[BANK], in its capacity as a "bank" as defined in Section 9-102 of Article 9 of
the UCC (in such capacity, the "Operating Account Bank"). Capitalized terms used
but not defined herein shall have the meanings assigned thereto in the Loan
Agreement dated as of October [__], 2004 (as amended, restated, supplemented or
otherwise modified from time to time, the "Loan Agreement") among the Borrower,
the Lenders party thereto, and HSH Nordbank AG, New York Branch, as
Administrative Agent (the "Administrative Agent"). All references herein to the
"UCC" means the Uniform Commercial Code as in effect from time to time in the
State of [____________].

      WHEREAS, pursuant to that certain Security Agreement, dated as of October
[__], 2004, between the Borrower and the Collateral Agent (the "Security
Agreement"), the Borrower has granted a security interest in substantially all
of its assets.

      NOW THEREFORE, the parties hereto hereby agree, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, as
follows:

      Section 2. Maintenance of Account. The Operating Account Bank hereby
confirms and agrees that it has established and shall maintain in the name of
the Borrower account number [_________] (the "Account"), and the Operating
Account Bank shall not change the name or account number of the Account without
the prior written consent of the Collateral Agent.

      Section 3. Control of the Account. If at any time the Operating Account
Bank shall receive any instructions originated by the Collateral Agent directing
the disposition of funds in the Account, the Operating Account Bank shall comply
with such instructions without further consent by the Borrower or any other
person. The Operating Account Bank hereby acknowledges that it has received
notice of the security interest of the Collateral Agent in the Account and
hereby acknowledges and consents to such lien.

      Section 4. Subordination of Lien; Waiver of Set-Off. In the event that the
Operating Account Bank has or subsequently obtains by agreement, by operation of
law or otherwise a security interest in the Account or any funds credited
thereto, the Operating Account Bank hereby agrees that such security interest
shall be subordinate to the security interest of the Collateral Agent. Money and
other items credited to the Account will not be subject to deduction, set-off,
banker's lien, or any other right in favor of any person other than the

                                    Exh. F-1
<PAGE>

Collateral Agent (except that the Operating Account Bank may set off (i) all
amounts due to the Operating Account Bank in respect of customary fees and
expenses for the routine maintenance and operation of the Account and (ii) the
face amount of any checks which have been credited to the Account but are
subsequently returned unpaid because of uncollected or insufficient funds).

      Section 5. Choice of Law. This Agreement shall be governed by the laws of
the State of [_________]. Regardless of any provision in any other agreement,
for purposes of the UCC and Article 9 of the UCC as adopted in the State of
[________] shall be deemed to be the Operating Account Bank's jurisdiction
(within the meaning of Section 9-304 of Article 9 of the UCC).

      Section 6. Conflict with Other Agreements.

      (a) In the event of any conflict between this Agreement (or any portion
thereof) and any other agreement now existing or hereafter entered into, the
terms of this Agreement shall prevail;

      (b) No amendment or modification of this Agreement or waiver of any right
hereunder shall be binding on any party hereto unless it is in writing and is
signed by all of the parties hereto; and

      (c) The Operating Account Bank hereby confirms and agrees that it has not
entered into, and until the termination of this Agreement, will not enter into,
any agreement with any other person relating to the Account and/or any funds
credited thereto pursuant to which it has agreed to comply with instructions
originated by such persons as contemplated by Section 9-104 of Article 9 of the
UCC.

      Section 7. Adverse Claims. The Operating Account Bank does not know of any
liens, claims or encumbrances relating to the Account. If any person asserts any
lien, encumbrance or adverse claim (including any writ, garnishment, judgment,
warrant of attachment, execution or similar process) against the Account, the
Operating Account Bank will promptly notify the Collateral Agent and the
Borrower thereof.

      Section 8. Maintenance of Account. In addition to, and not in lieu of the
obligation of the Operating Account Bank to honor instructions as set forth in
Section 2 hereof, the Operating Account Bank agrees to maintain the Account as
follows:

      (a) Statements and Confirmations. The Operating Account Bank will promptly
send copies of all statements, confirmations and other correspondence concerning
the Account simultaneously to each of the Borrower and the Administrative Agent
at their addresses set forth in Section 9.

      (b) Tax Reporting. All interest, if any, relating to the Account, shall be
reported to the Internal Revenue Service and all state and local taxing
authorities under the name and taxpayer identification number of the Borrower.

      (c) Withdrawal of Funds. If the Operating Account Bank (x) receives a
withdrawal request from the Borrower and (y) has not theretofore received a
notice from the Collateral

                                    Exh. F-2
<PAGE>

Agent (pursuant to Section 2 or otherwise) prohibiting withdrawals, then the
Operating Account Bank shall not be liable to the Collateral Agent for funding
the Borrower's withdrawal, it being acknowledged and agreed that the Collateral
Agent shall look solely to the Borrower in this regard.

      Section 9. Indemnification of Operating Account Bank. The Borrower hereby
agrees that (i) the Operating Account Bank is released from any and all
liabilities to the Borrower arising from the terms of this Agreement and the
compliance of the Operating Account Bank with the terms hereof, except to the
extent that such liabilities arise from the Operating Account Bank's negligence,
and (ii) the Borrower, its successors and assigns shall at all times indemnify
the Operating Account Bank from and against any and all claims, actions and
suits of others arising out of the terms of this Agreement or the compliance of
the Operating Account Bank with the terms hereof, except to the extent that such
arises from the Operating Account Bank's negligence.

      Section 10. Successors; Assignment. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns, except that the Borrower may not assign or transfer any of its
rights or obligations under this Agreement the prior written consent of the
Collateral Agent.

      Section 11. Notices. Any notice, request or other communication required
or permitted to be given under this Agreement shall be in writing and deemed to
have been properly given when delivered in person, or when sent by telecopy and

                            FORM OF JOINDER AGREEMENT

      This JOINDER AGREEMENT (this "Agreement") dated as of __________, 2004, is
made by and among [__________] (the "New Lender"), North America Capital Holding
Company (the "Borrower"), HSH Nordbank AG, New York Branch and Macquarie Bank,
Limited, as the Lenders (the "Existing Lenders"), and HSH Nordbank AG, New York
Branch, in its capacity as Administrative Agent (the "Administrative Agent") and
as Lead Arranger. All capitalized terms used herein but not otherwise defined
herein shall have the meaning assigned to such terms in the Loan Agreement.

      WHEREAS, the Borrower, the Administrative Agent and the Existing Lenders
have entered into a Loan Agreement, dated as of October [__], 2004 (the "Loan
Agreement"), pursuant to which the Lenders have extended Term Loans to the
Borrower in an aggregate principal amount equal to $130,000,000; and.

      WHEREAS, the New Lender, having received and reviewed a copy of the Loan
Agreement, desires to execute this Joinder Agreement to become a Term Loan
Lender in accordance with the requirements of Section 10.17 of the Loan
Agreement

      NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the New Lender hereby agrees as follows:

      1. Agreement to be Bound. In accordance with Section 10.17 of the Loan
Agreement, the New Lender, by executing and delivering this Agreement, and on
and as of the date hereof, hereby agrees to become a Term Loan Lender under the
Loan Agreement with the same force and effect as if originally named as a Term
Loan Lender thereunder, and agrees to be bound by all of the terms and
conditions of the Loan Agreement. Each reference to a "Term Loan Lender" or a
"Lender" in the Loan Agreement shall be deemed for all purposes to include the
New Lender.

      2. Commitments. The New Lender hereby agrees that its Term Loan
Commitments shall be as set forth in Schedule 2.1 attached hereto.

      3. Assignment and Assumption of Term Loans. The New Lender hereby agrees
to enter into Assignment and Assumption agreements with each of the Existing
Lenders concurrently herewith, pursuant to which the New Lender shall purchase
and assume its Pro Rata Share of the Term Loans advanced on the Initial
Disbursement Date and pay the purchase price payments thereunder.

      4. Replacement Schedules.

      Schedule 2.1 attached to the Loan Agreement, and the Commitments and Pro
      Rata Shares of each Lender shall be as set forth in such revised Schedule
      2.1. For the avoidance of doubt, the parties acknowledge that the Term
      Loan Commitments as set forth in such Schedule do not reflect any
      reduction for the Term Loans extended on the Initial Disbursement Date.

            (b) Schedule 2.5 attached hereto shall supersede and replace
      Schedule 2.5 attached to the Loan Agreement, and the required amortization
      of Class A Loan shall be as set forth in such revised Schedule 2.5.

necessary, to execute and deliver this Agreement and to consummate the
transactions contemplated hereby and to become a Term Loan Lender under the Loan
Agreement, (ii) it meets all requirements of an Eligible Assignee under the Loan
Agreement, (iii) from and after the date hereof, it shall be bound by the
provisions of the Loan Agreement as a Lender thereunder and, to the extent of
its Commitment, shall have the obligations of a Lender thereunder, (iv) it has
received a copy of the Loan Agreement and such other documents and information
as it has deemed appropriate to make its own credit analysis and decision to
enter into this Agreement and to become a Lender and the Issuing Bank on the

reliance on the Administrative Agent, the Lead Arranger or any other Lender, and
(v) attached hereto is any documentation (including tax forms) delivered by it
pursuant to the terms of the Loan Agreement, duly completed and executed by the
New Lender; and (b) agrees that (i) it will, independently and without reliance
on the Administrative Agent, the Lead Arranger or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Loan Documents, and (ii) it will perform in accordance with their terms all
of the obligations which by the terms of the Loan Documents are required to be
performed by it as a Term Loan Lender.

      8. Full Force and Effect. Except as expressly supplemented hereby, the
Loan Agreement shall remain in full force and effect.

      9. Governing Law. This Agreement shall be governed by, and shall be
construed and enforced in accordance with, the laws of the State of New York.
