extent necessary, include such reinsurance arrangements (with provisions for
direct access, if necessary) as shall be reasonably acceptable to the Collateral

                                   ARTICLE II

                                   THE CREDITS

            SECTION 2.01 COMMITMENTS. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly:

            (a) to make a Term B Loan to Borrower on the Closing Date in the
      principal amount not to exceed such Lender's Term B Commitment and, at any
      time and from time to time during the LC Facility Availability Period, to
      the extent provided in clause (ii) to the proviso of Section 2.18(e), to
      make a Term B Loan in an aggregate principal amount at any time
      outstanding that will not result in such Lender's LC Facility LC Exposure
      exceeding such Lender's original LC Facility Commitment;

            (b) to make Revolving Loans to Borrower, at any time and from time
      to time during the Revolving Availability Period in accordance with the
      terms hereof, in an aggregate principal amount at any time outstanding
      that will not result in such Lender's Revolving Exposure exceeding such
      Lender's Revolving Commitment; and

            (c) to make LC Facility Deposits into the LC Facility Deposit
      Account on the Closing Date in an aggregate principal amount not to exceed
      such LC Facility Lender's LC Facility Commitment.

            Amounts paid or prepaid in respect of Term B Loans may not be
reborrowed. Within the limits set forth in clause (b) above and subject to the
terms, conditions and limitations set forth herein, Borrower may borrow, pay or
prepay and reborrow Revolving Loans.

            SECTION 2.02 LOANS. (a) Each Loan (other than Swingline Loans) shall
be made as part of a Borrowing consisting of Loans made by the Lenders ratably
in accordance with their applicable Commitments; provided that the failure of
any Lender to make any Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender shall
be responsible for the failure of any other Lender to make any Loan required to
be made by such other

                                      -36-

<PAGE>

Lender). Except for Loans deemed made pursuant to Section 2.18(e)(ii), (x) ABR
Loans comprising any Borrowing shall be in an aggregate principal amount that is
(i) an integral multiple of $500,000 and not less than $1.0 million or (ii)
equal to the remaining available balance of the applicable Commitments and (y)
the Eurodollar Loans comprising any Borrowing shall be in an aggregate principal
amount that is (i) an integral multiple of $500,000 and not less than $1.0
million or (ii) equal to the remaining available balance of the applicable
Commitments.

            (b) Subject to Sections 2.11 and 2.12, each Borrowing shall be
comprised entirely of ABR Loans or Eurodollar Loans as Borrower may request
pursuant to Section 2.03. Each Lender may at its option make any Eurodollar Loan
by causing any domestic or foreign branch or Affiliate of such Lender to make
such Loan; provided that any exercise of such option shall not affect the
obligation of Borrower to repay such Loan in accordance with the terms of this
Agreement. Borrowings of more than one Type may be outstanding at the same time;
provided that Borrower shall not be entitled to request any Borrowing that, if
made, would result in more than eight (8) Eurodollar Borrowings outstanding
hereunder at any one time. For purposes of the foregoing, Borrowings having
different Interest Periods, regardless of whether they commence on the same
date, shall be considered separate Borrowings.

            (c) Except with respect to Loans made pursuant to Section
2.18(e)(ii), each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds to such
account in New York City as the Administrative Agent may designate not later
than 11:00 a.m., New York City time, and the Administrative Agent shall promptly
credit the amounts so received to an account as directed by Borrower in the
applicable Borrowing Request maintained with the Administrative Agent or, if a
Borrowing shall not occur on such date because any condition precedent herein
specified shall not have been met, return the amounts so received to the
respective Lenders.

            (d) Unless the Administrative Agent shall have received notice from
a Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above, and the Administrative Agent may, in
reliance upon such assumption, make available to Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available, then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, each of such Lender and Borrower
severally agrees to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to Borrower until the date such amount is repaid
to the Administrative Agent at (i) in the case of Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, the greater of the Federal Funds Effective Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation. If such Lender shall repay to the Administrative
Agent such corresponding amount, such amount shall constitute such Lender's Loan
as part of such Borrowing for purposes of this Agreement, and Borrower's
obligation to repay the Administrative Agent such corresponding amount pursuant
to this Section 2.02(d) shall cease.

            (e) Notwithstanding any other provision of this Agreement, Borrower
shall not be entitled to request, or to elect to convert or continue, any
Borrowing if the Interest Period requested with respect thereto would end after
the Revolving Maturity Date or the Term B Loan Maturity Date, as applicable.

            SECTION 2.03 BORROWING PROCEDURE. To request a Revolving Borrowing
or Term B Borrowing, Borrower shall deliver, by hand delivery or telecopy, a
duly completed and executed

                                      -37-

            (a) whether the requested Borrowing is to be a Borrowing of
      Revolving Loans or Term B Loans;

            (b) the aggregate amount of such Borrowing;

            (c) the date of such Borrowing, which shall be a Business Day;

            (d) whether such Borrowing is to be an ABR Borrowing or a Eurodollar
      Borrowing; provided that Eurodollar Borrowings shall not be available
      until the earlier of (i) August 31, 2004 and (ii) the date on which the
      Syndication Agent shall have notified Borrower that a Successful
      Syndication has been achieved ; provided further, however, that if on
      August 31, 2004, the Syndication Agent shall not have notified Borrower
      that a Successful Syndication has been achieved, then Borrower shall only
      be entitled to select Interest Periods for Eurodollar Borrowings of one
      month until it has been so notified;

            (e) in the case of a Eurodollar Borrowing, the initial Interest
      Period to be applicable thereto, which shall be a period contemplated by
      the definition of the term "Interest Period";

            (f) the location and number of Borrower's account to which funds are
      to be disbursed, which shall comply with the requirements of Section
      2.02(c); and

            (g) that the conditions set forth in Sections 4.02(b)-(d) have been
      satisfied as of the date of the notice.

            If no election as to the Type of Borrowing is specified, then the
requested Borrowing shall be an ABR Borrowing. If no Interest Period is
specified with respect to any requested Eurodollar Revolving Borrowing, then
Borrower shall be deemed to have selected an Interest Period of one month's
duration. Promptly following receipt of a Borrowing Request in accordance with
this Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender's Loan to be made as part of the
requested Borrowing.

            SECTION 2.04 EVIDENCE OF DEBT; REPAYMENT OF LOANS. (a) Borrower
hereby unconditionally promises to pay (i) to the Administrative Agent for the
account of each Term B Lender, the principal amount of each Term B Loan of such
Term B Lender as provided in Section 2.09, (ii) to the Administrative Agent for
the account of each Revolving Lender, the then unpaid principal amount of each
Revolving Loan of such Revolving Lender on the Revolving Maturity Date and (iii)
to the Swingline Lender, the then unpaid principal amount of each Swingline Loan
on the earlier of the Revolving Maturity Date and the first date after such
Swingline Loan is made that is the 15th or last day of a calendar month and is
at least two Business Days after such Swingline Loan is made; provided that on
each date that a Revolving Borrowing is made, Borrower shall repay all Swingline
Loans that were outstanding on the date such Borrowing was requested.

            (b) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of Borrower to such Lender
resulting from each Loan made by such

                                      -38-

<PAGE>

Lender from time to time, including the amounts of principal and interest
payable and paid to such Lender from time to time under this Agreement.

            (c) The Administrative Agent shall maintain accounts in which it
will record (i) the amount of each Loan made hereunder, the Type and Class
thereof and the Interest Period applicable thereto; (ii) the amount of any
principal or interest due and payable or to become due and payable from Borrower
to each Lender hereunder; and (iii) the amount of any sum received by the
Administrative Agent hereunder for the account of the Lenders and each Lender's
share thereof.

            (d) The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) above shall be prima facie evidence of the existence and
amounts of the obligations therein recorded; provided that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligations of Borrower to repay the
Loans in accordance with their terms.

            (e) Any Lender by written notice to Borrower (with a copy to the
Administrative Agent) may request that Loans of any Class made by it be
evidenced by a promissory note. In such event, Borrower shall prepare, execute
and deliver to such Lender a promissory note payable to the order of such Lender
(or, if requested by such Lender, to such Lender and its registered assigns) in
the form of Exhibit K-I, K-2 or K-3, as the case may be. Thereafter, the Loans
evidenced by such promissory note and interest thereon shall at all times
(including after assignment pursuant to Section 11.04) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

            SECTION 2.05 FEES.

            (a) Commitment Fee. Borrower agrees to pay to the Administrative
Agent for the account of each Lender a commitment fee (a "COMMITMENT FEE") equal
to the Applicable Fee per annum on the average daily unused amount of each
Revolving Commitment of such Lender during the period from and including the
date hereof to but excluding the date on which such Revolving Commitment
terminates. Accrued Commitment Fees shall be payable in arrears (A) on the last
Business Day of March, June, September and December of each year, commencing on
the first such date to occur after the date hereof, and (B) on the date on which
such Revolving Commitment terminates. Commitment Fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day). For purposes of
computing Commitment Fees with respect to Revolving Commitments, a Revolving
Commitment of a Lender shall be deemed to be used to the extent of the
outstanding Revolving Loans and Revolving LC Exposure of such Lender (and the
Swingline Exposure of such Lender shall be disregarded for such purpose).

            (b) Administrative Agent Fees. Borrower agrees to pay to the
Administrative Agent, for its own account, the administrative fees set forth in
the Fee Letter or such other fees payable in the amounts and at the times
separately agreed upon between Borrower and the Administrative Agent (the

Administrative Agent for the account of each Revolving Lender a participation
fee ("LC PARTICIPATION FEE") with respect to its participations in Revolving
Letters of Credit, which shall accrue at a rate equal to the Applicable Margin
from time to time used to determine the interest rate on Eurodollar Revolving
Loans pursuant to Section 2.06 on the average daily amount of such Lender's
Revolving LC Exposure (excluding any portion thereof attributable to
Reimbursement Obligations) during the period from and including the Closing Date
to but excluding the later of the date on which such Lender's Revolving
Commitment terminates and the

                                      -39-

<PAGE>

date on which such Lender ceases to have any Revolving LC Exposure, and (ii) to
the Issuing Bank a fronting fee ("FRONTING FEE"), which shall accrue at the rate
of 0.125% per annum on the average daily amount of the Revolving LC Exposure
(excluding any portion thereof attributable to Reimbursement Obligations) during
the period from and including the Closing Date to but excluding the later of the
date of termination of the Revolving Commitments and the date on which there
ceases to be any Revolving LC Exposure, as well as the Issuing Bank's customary
fees with respect to the issuance, amendment, renewal or extension of any
Revolving Letter of Credit or processing of drawings thereunder. Accrued LC
Participation Fees and Fronting Fees shall be payable in arrears (i) on the last
Business Day of March, June, September and December of each year, commencing on
the first such date to occur after the Closing Date, and (ii) on the date on
which the Revolving Commitments terminate. Any such fees accruing after the date
on which the Revolving Commitments terminate shall be payable on demand. Any
other fees payable to the Issuing Bank pursuant to this paragraph shall be
payable within 10 days after demand therefor. All LC Participation Fees and
Fronting Fees shall be computed on the basis of a year of 360 days and shall be
payable for the actual number of days elapsed (including the first day but
excluding the last day).

            (d) LC Facility Fee. Borrower agrees to pay (i) in addition to the
fees payable to the LC Facility Lenders pursuant to Section 2.19(b), to the
Administrative Agent for the account of each LC Facility Lender a participation
fee with respect to its participations in LC Facility Letters of Credit ("LC
FACILITY LC FEES"), which shall accrue at a rate equal to the Applicable Margin
from time to time used to determine the interest rate on Eurodollar Term Loans
pursuant to Section 2.06 on the average daily amount of such LC Facility
Lender's LC Facility Deposit during the period from and including the Closing
Date to but excluding the date on which the entire amount of such Lender's LC
Facility Deposit is returned to it, and (ii) the LC Facility Issuing Bank's
customary fees with respect to the amendment, renewal or extension of any LC
Facility Letter of Credit, or processing of drawings thereunder. Accrued
participation fees shall be payable (i) on the last Business Day of March, June,
September and December of each year, commencing on the first such date to occur
after the Closing Date, and (ii) on the date on which the full amounts of the LC
Facility Deposits are returned to the LC Facility Lenders. Any other fees
payable to the LC Facility Issuing Bank pursuant to this paragraph shall be
payable within ten (10) days after demand. All participation fees in respect of
LC Facility Letters of Credit shall be computed on the basis of a year of 360
days and shall be payable for the actual number of days elapsed (including the
first day but excluding the last day).

            (e) All Fees shall be paid on the dates due, in immediately
available funds in dollars, to the Administrative Agent for distribution, if and
as appropriate, among the Lenders, except that Borrower shall pay the Fronting
Fees directly to the Issuing Bank. Once paid, none of the Fees shall be
refundable under any circumstances.

            SECTION 2.06 INTEREST ON LOANS. (a) Subject to the provisions of
Section 2.06(c), the Loans comprising each ABR Borrowing, including each
Swingline Loan, shall bear interest at a rate per annum equal to the Alternate
Base Rate plus the Applicable Margin in effect from time to time.

            (b) Subject to the provisions of Section 2.06(c), the Loans
comprising each Eurodollar Borrowing shall bear interest at a rate per annum
equal to the Adjusted LIBOR Rate for the Interest Period in effect for such
Borrowing plus the Applicable Margin in effect from time to time.

            (c) Notwithstanding the foregoing, during the continuance of an
Event of Default, all Obligations shall, to the extent permitted by applicable
law, bear interest, after as well as before judgment, at a per annum rate equal
to (i) in the case of principal of or interest on any Loan, 2% plus the rate
otherwise applicable to such Loan as provided in the preceding paragraphs of
this Section 2.06 or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Revolving Loans as provided in Section 2.06(a) (in either
case, the "DEFAULT RATE").

                                      -40-

<PAGE>

            (d) Accrued interest on each Loan shall be payable in arrears on
each Interest Payment Date for such Loan; provided that (i) interest accrued
pursuant to Section 2.06(c) shall be payable on demand, (ii) in the event of any
repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving
Loan or a Swingline Loan), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii)
in the event of any conversion of any Eurodollar Loan prior to the end of the
current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion.

            (e) All interest hereunder shall be computed on the basis of a year
of 360 days, except that interest computed by reference to the Alternate Base
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 Alternate
Base Rate or Adjusted LIBOR Rate shall be determined by the Administrative Agent
in accordance with the provisions of this Agreement and such determination shall
be conclusive absent manifest error.

            SECTION 2.07 TERMINATION AND REDUCTION OF COMMITMENTS AND LC
FACILITY DEPOSIT. (a) The Term B Commitments and the LC Facility Commitments
shall automatically terminate at 5:00 p.m., New York City time, on the Closing
Date. The Revolving Commitments, the Swingline Commitment and the Revolving LC
Commitment shall automatically terminate on the Revolving Maturity Date.
Notwithstanding the foregoing, all the Commitments shall automatically terminate
at 5:00 p.m., New York City time, on August 1, 2004, if the initial Credit
Extension shall not have occurred by such time.

            (b) At its option, Borrower may at any time terminate, or from time
to time permanently reduce, the Commitments of any Class; provided that (i) each
reduction of the Commitments of any Class shall be in an amount that is an
integral multiple of $500,000 and not less than $1.0 million and (ii) the
Revolving Commitments shall not be terminated or reduced if, after giving effect
to any concurrent prepayment of the Revolving Loans in accordance with Section
2.10, the aggregate amount of Revolving Exposures would exceed the aggregate
amount of Revolving Commitments.

            (c) At its option, Borrower may at any time, or from time to time,
direct the Administrative Agent to reduce the Total LC Facility Deposit;
provided that (i) each reduction of the LC Facility Deposits shall be in an
amount that is an integral multiple of $500,000 and not less than $1.0 million,
and (ii) the LC Facility Deposits shall not be reduced, if after giving effect
to such reduction (and to the provisions of Section 2.18(a)), the aggregate LC
Facility LC Exposure would exceed the Total LC Facility Deposit. In the event
the LC Facility Deposits shall be reduced as provided in the preceding sentence,
the Administrative Agent will return all amounts invested in the LC Facility
Deposit Account in excess of the reduced Total LC Facility Deposit to the LC
Facility Lenders, ratably in accordance with their Pro Rata Percentages of the
Total LC Facility Deposit (as determined immediately prior to such reduction).

            (d) Borrower shall notify the Administrative Agent in writing of any
election to terminate or reduce the Commitments under Section 2.07(b) or Total
LC Facility Deposits under Section 2.07(c) at least three (3) Business Days
prior to the effective date of such termination or reduction, specifying such
election and the effective date thereof. Promptly following receipt of any
notice, the Administrative Agent shall advise the Lenders of the contents
thereof. Each notice delivered by Borrower pursuant to this Section shall be
irrevocable. Any termination or reduction of the Commitments of any Class or LC
Facility Deposits, as the case may be, shall be permanent. Each reduction of the
Commitments of any Class or LC Facility Deposits, as the case may be, shall be
made ratably among the Lenders in accordance with their respective Commitments
of such Class or LC Facility Deposits, as the case may be.

            SECTION 2.08 INTEREST ELECTIONS. (a) Each Revolving Borrowing and
Term B Borrowing initially shall be of the Type specified in the applicable
Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an
initial Interest Period as specified in such Borrowing Request. Thereafter,
Borrower may elect to convert such Borrowing to a different Type or to continue
such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest
Periods therefor, all as provided in this Section. Borrower may elect different
options with respect to different portions of the affected Borrowing, in which
case each such portion shall be allocated ratably among the Lenders holding the
Loans comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing. Notwithstanding anything to the
contrary, Borrower shall not be entitled to request any conversion or
continuation that, if made, would result in more than eight (8) Eurodollar
Borrowings outstanding hereunder at any one time. This Section shall not apply
to Swingline Borrowings, which may not be converted or continued.

            (b) To make an election pursuant to this Section, Borrower shall
deliver, by hand delivery or telecopy, a duly completed and executed Interest
Election Request to the Administrative Agent not later than the time that a
Borrowing Request would be required under Section 2.03 if Borrower were
requesting a Revolving Borrowing or Term B Borrowing of the Type resulting from
such election to be made on the effective date of such election. Each Interest
Election Request shall be irrevocable.

            (c) Each Interest Election Request shall specify the following
information in compliance with Section 2.02:

            (i) the Borrowing to which such Interest Election Request applies
      and, if different options are being elected with respect to different
      portions thereof, or if outstanding Borrowings are being combined,
      allocation to each resulting Borrowing (in which case the information to
      be specified pursuant to clauses (iii) and (iv) below shall be specified
      for each resulting Borrowing);

            (ii) the effective date of the election made pursuant to such
      Interest Election Request, which shall be a Business Day;

            (iii) whether the resulting Borrowing is to be an ABR Borrowing or a
      Eurodollar Borrowing; provided that Eurodollar Borrowings shall not be
      available until the earlier of (i) August 31, 2004 and (ii) the date on
      which the Syndication Agent shall have notified Borrower that a Successful
      Syndication has been achieved; provided further, however, that if on
      August 31, 2004, the Syndication Agent shall not have notified Borrower
      that a Successful Syndication has been achieved, then Borrower shall only
      be entitled to select Interest Periods for Eurodollar Borrowings of one
      month until it has been so notified; and

            (iv) if the resulting Borrowing is a Eurodollar Borrowing, the
      Interest Period to be applicable thereto after giving effect to such
      election, which shall be a period contemplated by the definition of the
      term "Interest Period".

            If any such Interest Election Request requests a Eurodollar
Borrowing but does not specify an Interest Period, then Borrower shall be deemed
to have selected an Interest Period of one month's duration.

            (d) Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

                                      -42-
<PAGE>

            (e) If an Interest Election Request with respect to a Eurodollar
Borrowing is not timely delivered prior to the end of the Interest Period
applicable thereto, then, unless such Borrowing is repaid as provided herein, at
the end of such Interest Period such Borrowing shall be converted to an ABR
Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default
has occurred and is continuing, the Administrative Agent or the Required Lenders
may require, by notice to Borrower, that (i) no outstanding Borrowing may be
converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each
Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

            SECTION 2.09 AMORTIZATION OF TERM B BORROWINGS. (a) Borrower
shall pay to the Administrative Agent, for the account of the Lenders, on the
dates set forth on Annex I, or if any such date is not a Business Day, on the
immediately preceding Business Day (each such date, a "TERM B LOAN REPAYMENT
DATE"), a principal amount of the Term B Loans equal to the amount set forth on
Annex I for such date (as adjusted from time to time (i) pursuant to Section
2.10(h) or (ii) in the event of a conversion of an LC Facility LC Disbursement
into Term B Loans pursuant to Section 2.18(e), to increase such amortization
amount to proportionally reflect any additional Term B Loans made after the
Closing Date), together with accrued and unpaid interest on the principal amount
to be paid to but excluding the date of such payment.

            (b) To the extent not previously paid, all Term B Loans shall be due
and payable on the Term B Loan Maturity Date.

            SECTION 2.10 OPTIONAL AND MANDATORY PREPAYMENTS.

            (a) Optional Prepayments. Borrower shall have the right at any time
and from time to time to prepay any Borrowing, in whole or in part, subject to
the requirements of this Section 2.10; provided that each partial prepayment
shall be in an amount that is an integral multiple of $500,000 and not less than
$1.0 million.

            (b) Revolving Loan Prepayments. (i) In the event of the termination
of all the Revolving Commitments, Borrower shall, on the date of such
termination, repay or prepay all its outstanding Revolving Borrowings and all
outstanding Swingline Loans and replace all outstanding Revolving Letters of
Credit or cash collateralize all outstanding Revolving Letters of Credit in
accordance with the procedures set forth in Section 2.18(i).

            (ii) In the event of any partial reduction of the Revolving
Commitments, then (x) at or prior to the effective date of such reduction, the
Administrative Agent shall notify Borrower and the Revolving Lenders of the sum
of the Revolving Exposures after giving effect thereto and (y) if the sum of the
Revolving Exposures would exceed the aggregate amount of Revolving Commitments
after giving effect to such reduction, then Borrower shall, on the date of such
reduction, first, repay or prepay Swingline Loans, second, repay or prepay
Revolving Borrowings and third, replace outstanding Revolving Letters of Credit
or cash collateralize outstanding Revolving Letters of Credit in accordance with
the procedures set forth in Section 2.18(i), in an aggregate amount sufficient
to eliminate such excess.

            (iii) In the event that the sum of all Lenders' Revolving Exposures
exceeds the Revolving Commitments then in effect, Borrower shall, without notice
or demand, immediately first, repay or prepay Swingline Loans second, repay or
prepay Revolving Borrowings, and third, replace outstanding Revolving Letters of
Credit or cash collateralize outstanding Revolving Letters of Credit in
accordance with the procedures set forth in Section 2.18(i), in an aggregate
amount sufficient to eliminate such excess.

                                      -43-

<PAGE>

            (iv) In the event that the aggregate Revolving LC Exposure exceeds
the Revolving LC Commitment then in effect, Borrower shall, without notice or
demand, immediately replace outstanding Revolving Letters of Credit or cash
collateralize outstanding Revolving Letters of Credit in accordance with the
procedures set forth in Section 2.18(i), in an aggregate amount sufficient to
eliminate such excess.

            (c) Asset Sales. Not later than one Business Day following the
receipt of any Net Cash Proceeds of any Asset Sale by Borrower or any of its
Subsidiaries, Borrower shall apply 100% of such Net Cash Proceeds to make
prepayments in accordance with Sections 2.10(h) and (i); provided that:

            (i) so long as no Default shall then exist or arise therefrom, no
      such prepayment shall be required under this Section 2.10(c)(i) with
      respect to (A) any Asset Sale permitted by Section 6.06(a), (B) the
      disposition of property which constitutes a Casualty Event, or (C) Asset
      Sales for fair market value resulting in no more than $100,000 in Net Cash
      Proceeds per Asset Sale (or series of related Asset Sales) and less than
      $1.0 million in Net Cash Proceeds in any fiscal year; provided that clause
      (C) shall not apply in the case of any Asset Sale described in clause (b)
      of the definition thereof; and

            (ii) so long as no Default shall then exist or would arise therefrom
      and the aggregate of such Net Cash Proceeds of Asset Sales shall not
      exceed $5.0 million in any fiscal year of Borrower, such proceeds shall
      not be required to be so applied on such date to the extent that (A)
      Borrower shall have delivered an Officers' Certificate to the
      Administrative Agent on or prior to such date stating that such Net Cash
      Proceeds are expected to be reinvested in fixed or capital assets within
      180 days following the date of such Asset Sale (which Officers'
      Certificate shall set forth the estimates of the proceeds to be so
      expended); and (B) all Net Cash Proceeds in respect of all Asset Sales
      (other than those referred to in clause (C) of Section 2.10(c)(i)) in
      excess of $5.0 million in the aggregate at any time shall be held in the
      Collateral Account and released therefrom only in accordance with the
      provisions of Article IX; provided that if all or any portion of such Net
      Cash Proceeds is not so reinvested within such 180-day period, such unused
      portion shall be applied on the last day of such period as a mandatory
      prepayment as provided in this Section 2.10(c); and provided, further,
      that if the property subject to such Asset Sale constituted Collateral,
      then all property purchased with the Net Cash Proceeds thereof pursuant to
      this subsection shall be made subject to the Lien of the applicable
      Security Documents in favor of the Collateral Agent, for its benefit and
      for the benefit of the other Secured Parties in accordance with Sections
      5.11 and 5.12.

With respect to the sale of any Collateral that is sold as permitted by this
Agreement, such Collateral (unless sold to a Company) shall be sold free and
clear of the Liens created by the Security Documents.

            (d) Debt Issuance or Preferred Stock Issuance. Not later than one
(1) Business Day following the receipt of any Net Cash Proceeds of any Debt
Issuance or Preferred Stock Issuance by Borrower or any of its Subsidiaries,
Borrower shall make prepayments in accordance with Sections 2.10(h) and (i) in
an aggregate principal amount equal to 100% of such Net Cash Proceeds.

            (e) Equity Issuance. Not later than one (1) Business Day following
the receipt of any Net Cash Proceeds of any Equity Issuance (other than
compensation options), Borrower shall make prepayments in accordance with
Sections 2.10(h) and (i) in an aggregate principal amount equal to 50% of such
Net Cash Proceeds.

            (f) Casualty Events. Not later than one (1) Business Day following
the receipt of any Net Cash Proceeds from a Casualty Event by Borrower or any of
its Subsidiaries, Borrower shall ap-

                                      -44-
<PAGE>

ply an amount equal to 100% of such Net Cash Proceeds to make prepayments in
accordance with Sections 2.10(h) and (i); provided that:

            (i) so long as no Default shall then exist or arise therefrom, such
      proceeds shall not be required to be so applied on such date to the extent
      that (A) in the event such Net Cash Proceeds shall not exceed $10.0
      million, Borrower shall have delivered an Officers' Certificate to the
      Administrative Agent on or prior to such date stating that such proceeds
      are expected to be used, or (B) in the event that such Net Cash Proceeds
      exceed $10.0 million, the Administrative Agent has elected by notice to
      Borrower on or prior to such date to require such proceeds to be used, in
      each case, to repair, replace or restore any property in respect of which
      such Net Cash Proceeds were paid, no later than 180 days following the
      date of receipt of such proceeds; provided that if the property subject to
      such Casualty Event constituted Collateral under the Security Documents,
      then all property purchased with the Net Cash Proceeds thereof pursuant to
      this subsection shall be made subject to the Lien of the applicable
      Security Documents in favor of the Collateral Agent, for its benefit and
      for the benefit of the other Secured Parties in accordance with Sections
      5.11 and 5.12;

            (ii) all Net Cash Proceeds in respect of all Casualty Events in
      excess of $1.0 million in the aggregate shall be held in the Collateral
      Account and released therefrom only in accordance with the provisions of
      Article IX; and

            (iii) if any portion of such Net Cash Proceeds shall not be so
      applied within such 180-day period, such unused portion shall be applied
      on the last day of such period as a mandatory prepayment as provided in
      this Section 2.10(f).

            (g) Excess Cash Flow. No later than the earlier of (i) 90 days after
the end of each Excess Cash Flow Period and (ii) the date on which the financial
statements with respect to such fiscal year in which such Excess Cash Flow
Period occurs are delivered pursuant to Section 5.01(a), Borrower shall make
prepayments in accordance with Sections 2.10(h) and (i) in an aggregate
principal amount equal to 50% (which amount will be reduced to 25% if Borrower's
Asset Coverage Ratio for the immediately preceding Test Period is greater than
or equal to 2.25 to 1.0) of Excess Cash Flow for the Excess Cash Flow Period
then ended.

            (h) Application of Prepayments. (i) Prior to any optional or
mandatory prepayment hereunder, Borrower shall select the Borrowing or
Borrowings to be prepaid and shall specify such selection in the notice of such
prepayment pursuant to Section 2.10(i), subject to the provisions of this
Section 2.10(h). Any prepayments of Term B Loans pursuant to Section 2.10(c),
(d), (e), (f) or (g) shall be applied to reduce scheduled prepayments required
under Section 2.09(a) on a pro rata basis among the prepayments remaining to be
made on each other Term B Loan Repayment Date. After application of mandatory
prepayments described above in this Section 2.10(h) and to the extent there are
mandatory prepayment amounts remaining after such application, the Revolving
Commitments shall be permanently reduced ratably among the Revolving Lenders in
accordance with their applicable Revolving Commitments in an aggregate amount
equal to such excess, and Borrower shall comply with Section 2.10(b).

            (ii) Amounts to be applied pursuant to this Section 2.10 to the
prepayment of Term B Loans and Revolving Loans shall be applied, as applicable,
first to reduce outstanding ABR Term Loans and ABR Revolving Loans,
respectively. Any amounts remaining after each such application shall be applied
to prepay Eurodollar Term B Loans or Eurodollar Revolving Loans, as applicable.
Notwithstanding the foregoing, if the amount of any prepayment of Loans required
under this Section 2.10 shall be in excess of the amount of the ABR Loans at the
time outstanding (an "EXCESS AMOUNT"), only the portion of the amount of such
prepayment as is equal to the amount of such outstanding ABR Loans shall be
im-

                                      -45-
<PAGE>

mediately prepaid and, at the election of Borrower, the balance of such required
prepayment shall be either (A) deposited in the Collateral Account and applied
to the prepayment of Eurodollar Loans on the last day of the then next-expiring
Interest Period for Eurodollar Loans; provided that (i) interest in respect of
such Excess Amount shall continue to accrue thereon at the rate provided
hereunder for the Loans which such Excess Amount is intended to repay until such
Excess Amount shall have been used in full to repay such Loans and (ii) at any
time while an Event of Default has occurred and is continuing, the
Administrative Agent may, and upon written direction from the Required Lenders
shall, apply any or all proceeds then on deposit in the Collateral Account to
the payment of such Loans in an amount equal to such Excess Amount or (B)
prepaid immediately, together with any amounts owing to the Lenders under
Section 2.13.

            (i) Notice of Prepayment. Borrower shall notify the Administrative
Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender)
by written notice of any prepayment hereunder (i) in the case of prepayment of a
Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three
Business Days before the date of prepayment, (ii) in the case of prepayment of
an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business
Day before the date of prepayment and (iii) in the case of prepayment of a
Swingline Loan, not later than 11:00 a.m., New York City time, on the date of
prepayment. Each such notice shall be irrevocable. Each such notice shall
specify the prepayment date, the principal amount of each Borrowing or portion
thereof to be prepaid and, in the case of a mandatory prepayment, a reasonably
detailed calculation of the amount of such prepayment. Promptly following
receipt of any such notice (other than a notice relating solely to Swingline
Loans), the Administrative Agent shall advise the Lenders of the contents
thereof. Such notice to the Lenders may be by electronic communication. Each
partial prepayment of any Borrowing shall be in an amount that would be
permitted in the case of a Credit Extension of the same Type as provided in
Section 2.02, except as necessary to apply fully the required amount of a
mandatory prepayment. Each prepayment of a Borrowing shall be applied ratably to
the Loans included in the prepaid Borrowing and otherwise in accordance with
this Section 2.10. Prepayments shall be accompanied by accrued interest to the
extent required by Section 2.06.

            SECTION 2.11 ALTERNATE RATE OF INTEREST. If prior to the
commencement of any Interest Period for a Eurodollar Borrowing:

            (a) the Administrative Agent determines (which determination shall
      be final and conclusive absent manifest error) that adequate and
      reasonable means do not exist for ascertaining the Adjusted LIBOR Rate for
      such Interest Period; or

            (b) the Administrative Agent is advised in writing by the Required
      Lenders that the Adjusted LIBOR Rate for such Interest Period will not
      adequately and fairly reflect the cost to such Lenders of making or
      maintaining their Loans included in such Borrowing for such Interest
      Period;

then the Administrative Agent shall give written notice thereof to Borrower and
the Lenders as promptly as practicable thereafter and, until the Administrative
Agent notifies Borrower and the Lenders that the circumstances giving rise to
such notice no longer exist, (i) any Interest Election Request that requests the
conversion of any Borrowing to, or continuation of any Borrowing as, a
Eurodollar Borrowing shall be ineffective and (ii) if any Borrowing Request
requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR
Borrowing.

                                      -46-
<PAGE>

            SECTION 2.12 INCREASED COSTS. (a) If any Change in Law shall:

            (i) impose, modify or deem applicable any reserve, special deposit
      or similar requirement against property of, deposits with or for the
      account of, or credit extended by, any Lender (except any such reserve
      requirement reflected in the Adjusted LIBOR Rate) or the Issuing Bank; or

            (ii) impose on any Lender or the Issuing Bank or the LC Facility
      Issuing Bank or the London interbank market any other condition affecting
      this Agreement or Eurodollar Loans made by such Lender or any Letter of
      Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender, the
Issuing Bank, the LC Facility Issuing Bank or such Lender's or the Issuing
Bank's or the LC Facility Issuing Bank's holding company, if any, of
participating in, issuing or maintaining any Letter of Credit or to reduce the
amount of any sum received or receivable by such Lender or the Issuing Bank or
the LC Facility Issuing Bank hereunder (whether of principal, interest or
otherwise), then Borrower will pay to such Lender or the Issuing Bank or the LC
Facility Issuing Bank, as the case may be, such additional amount or amounts as
will compensate such Lender or the Issuing Bank or the LC Facility Issuing Bank,
as the case may be, for such additional costs incurred or reduction suffered, it
being understood that, to the extent duplicative of the provisions of Section
2.15, this Section 2.12 shall not apply to Taxes. If any Lender requests
compensation by Borrower under this Section 2.12, Borrower may, by notice to
such Lender (with a copy to the Administrative Agent), suspend the obligation of
such Lender to make or continue Eurodollar Loans or to convert all or part of
the ABR Loans owing to such Lender into Eurodollar Loans, until the event or
condition giving rise to such request ceases to be in effect; provided that such
suspension shall not affect the right of such Lender to receive the compensation
so requested.

            (b) If any Lender or the Issuing Bank or the LC Facility Issuing
Bank determines (in good faith, but in its sole absolute discretion) 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 or the LC
Facility Issuing Bank's capital or on the capital of such Lender's or the
Issuing Bank's or the LC Facility Issuing Bank's holding company, if any, as a
consequence of this Agreement or the Loans made by, or participations in letters
of credit held by, such Lender, or the Letters of Credit issued by the Issuing
Bank or the LC Facility Issuing Bank, to a level below that which such Lender or
the Issuing Bank or the LC Facility Issuing Bank or such Lender's or the Issuing
Bank's or the LC Facility 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 or the LC Facility Issuing Bank's policies and the policies of such
Lender's or the Issuing Bank's or the LC Facility Issuing Bank's holding company
with respect to capital adequacy), then from time to time Borrower will pay to
such Lender or the Issuing Bank or the LC Facility Issuing Bank, as the case may
be, such additional amount or amounts as will compensate such Lender or the
Issuing Bank or the LC Facility Issuing Bank or such Lender's or the Issuing
Bank's or the LC Facility Issuing Bank's holding company for any such reduction
suffered.

            (c) A certificate of a Lender or the Issuing Bank or the LC Facility
Issuing Bank setting forth in reasonable detail the amount or amounts necessary
to compensate such Lender or the Issuing Bank or the LC Facility Issuing Bank or
its holding company, as the case may be, as specified in paragraph (a) or (b) of
this Section 2.12 shall be delivered to Borrower (with a copy to the
Administrative Agent) and shall be conclusive and binding absent manifest error.
Borrower shall pay such Lender or the Issuing Bank or the LC Facility Issuing
Bank, as the case may be, the amount shown as due on any such certificate within
5 days after receipt thereof.

                                      -47-
<PAGE>

            (d) Each Lender shall promptly notify Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Lender to compensation pursuant to this
Section 2.12. Failure or delay on the part of any Lender or the Issuing Bank or
the LC Facility Issuing Bank to demand compensation pursuant to this Section
2.12 shall not constitute a waiver of such Lender's or the Issuing Bank's or the
LC Facility Issuing Bank's right to demand such compensation; provided that
Borrower shall not be required to compensate a Lender or the Issuing Bank or the
LC Facility Issuing Bank pursuant to this Section 2.12 for any increased costs
or reductions incurred more than 180 days prior to the date that such Lender or
the Issuing Bank or the LC Facility Issuing Bank, as the case may be, notifies
Borrower of the Change in Law giving rise to such increased costs or reductions
and of such Lender's or the Issuing Bank's or the LC Facility Issuing Bank's
intention to claim compensation therefor; 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 not begin earlier than the date of
effectiveness of the Change in Law.

            SECTION 2.13 BREAKAGE PAYMENTS. In the event of (a) the payment or
prepayment, whether optional or mandatory, of any principal of any Eurodollar
Loan earlier than the last day of an Interest Period applicable thereto
(including as a result of an Event of Default), (b) the conversion of any
Eurodollar Loan earlier than the last day of the Interest Period applicable
thereto, (c) the failure to borrow, convert, continue or prepay any Revolving
Loan or Term B Loan on the date specified in any notice delivered pursuant
hereto or (d) the assignment of any Eurodollar Loan earlier than the last day of
the Interest Period applicable thereto as a result of a request by Borrower
pursuant to Section 2.16, then, in any such event, Borrower shall compensate
each Lender for the loss, cost and expense attributable to such event. In the
case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be
deemed to include an amount determined by such Lender to be the excess, if any,
of (i) the amount of interest which would have accrued on the principal amount
of such Loan had such event not occurred, at the Adjusted LIBOR Rate that would
have been applicable to such Loan, for the period from the date of such event to
the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow, convert or continue, for the period that would have been the
Interest Period for such Loan), over (ii) the amount of interest which would
accrue on such principal amount for such period at the interest rate which such
Lender would bid were it to bid, at the commencement of such period, for dollar
deposits of a comparable amount and period from other banks in the Eurodollar
market. A certificate of any Lender setting forth in reasonable detail any
amount or amounts that such Lender is entitled to receive pursuant to this
Section 2.13 shall be delivered to Borrower (with a copy to the Administrative
Agent) and shall be conclusive and binding absent manifest error. Borrower shall
pay such Lender the amount shown as due on any such certificate within 5 days
after receipt thereof.

            SECTION 2.14 PAYMENTS GENERALLY; PRO RATA TREATMENT; SHARING OF
SETOFFS. (a) Borrower shall make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest, fees
or Reimbursement Obligations, or of amounts payable under Section 2.12, 2.13 or
2.15, or otherwise) on or before the time expressly required hereunder or under
such other Loan Document for such payment (or, if no such time is expressly
required, prior to 2:00 p.m., New York City time), on the date when due, in
immediately available funds, without setoff, deduction or counterclaim. Any
amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at 677 Washington
Boulevard, Stamford, Connecticut, except payments to be made directly to the
Issuing Bank, LC Facility Issuing Bank or Swingline Lender as expressly provided
herein and except that payments pursuant to Sections 2.12, 2.13, 2.15 and 11.03
shall be made directly to the persons entitled thereto and payments pursuant to
other Loan Documents shall be made to the persons specified therein. The
Administrative Agent shall distribute any such payments received by it for the
account of any other person to the appropriate recipient promptly following
receipt thereof. If any payment under any Loan

                                      -48-
<PAGE>

Document shall be due on a day that is not a Business Day, unless specified
otherwise, the date for payment shall be extended to the next succeeding
Business Day, and, in the case of any payment accruing interest, interest
thereon shall be payable for the period of such extension. All payments under
each Loan Document shall be made in dollars, except as expressly specified
otherwise.

            (b) If at any time insufficient funds are received by and available
to the Administrative Agent to pay fully all amounts of principal, Reimbursement
Obligations, 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
and Reimbursement Obligations then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of principal and Reimbursement
Obligations then due to such parties.

            (c) If any Lender shall, by exercising any right of setoff or
counterclaim or otherwise (including by exercise of its rights under Section 9.1
of the Security Agreement), obtain payment in respect of any principal of or
interest on any of its Revolving Loans, Term B Loans or participations in LC
Disbursements or Swingline Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Revolving Loans, Term B Loans
and participations in LC Disbursements and Swingline Loans 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 Revolving Loans, Term B Loans and participations in LC
Disbursements and Swingline Loans of 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 Revolving Loans, Term B Loans and participations in LC
Disbursements and Swingline Loans; 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 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 or participations
in LC Disbursements to any assignee or participant, other than to Borrower or
any of its Subsidiaries or Affiliates (as to which the provisions of this
paragraph shall apply). Each Loan Party consents to the foregoing and agrees, to
the extent it may effectively do so under applicable law, that any Lender
acquiring a participation pursuant to the foregoing arrangements may exercise
against such Loan Party rights of setoff and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of such Loan
Party in the amount of such participation. If under applicable bankruptcy,
insolvency or any similar law any Secured Party receives a secured claim in lieu
of a setoff or counterclaim to which this Section 2.14(c) applies, such Secured
Party shall to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights to which the Secured Party
is entitled under this Section 2.14(c) to share in the benefits of the recovery
of such secured claim.

            (d) Unless the Administrative Agent shall have received notice from
Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders hereunder that Borrower will not make such
payment, the Administrative Agent may assume that Borrower has made such payment
on such date in accordance herewith and may, in reliance upon such assumption,
distribute to the Lenders the amount due. In such event, if Borrower has not in
fact made such payment, then each of the Lenders severally agrees to repay to
the Administrative Agent forthwith on demand the amount so distributed to such
Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

                                      -49-
<PAGE>

            (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.02(c), 2.14(d), 2.17(d), 2.18(d), 2.18(e) or
11.03(d), then the Administrative Agent may, in its discretion (notwithstanding
any contrary provision hereof), apply any amounts thereafter received by the
Administrative Agent for the account of such Lender to satisfy such Lender's
obligations under such Sections until all such unsatisfied obligations are fully
paid.

            SECTION 2.15 TAXES. (a) Any and all payments by or on account of
any obligation of Borrower hereunder or under any other Loan Document shall be
made without setoff, counterclaim or other defense and free and clear of and
without deduction or withholding for any and all Indemnified Taxes; provided
that if Borrower shall be required by law to deduct any Indemnified Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions or withholdings
applicable to additional sums payable under this Section 2.15) the
Administrative Agent, any Lender, the Issuing Bank or the LC Facility Issuing
Bank as the case may be, receives an amount equal to the sum it would have
received had no such deductions or withholdings been made, (ii) Borrower shall
make such deductions or withholdings and (iii) Borrower shall pay the full
amount deducted or withheld to the relevant Governmental Authority in accordance
with applicable law.

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

            (c) Borrower shall indemnify the Administrative Agent, each Lender,
the Issuing Bank and the LC Facility Issuing Bank, as applicable, within ten
(10) Business Days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender,
the Issuing Bank or the LC Facility Issuing Bank, as applicable, on or with
respect to any payment by or on account of any obligation of 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
2.15) 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
Borrower by a Lender, the Issuing Bank, the LC Facility Issuing Bank or by the
Administrative Agent on its own behalf or on behalf of a Lender, the Issuing
Bank or the LC Facility Issuing Bank shall be conclusive absent manifest error.

            (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes and in any event within 30 days of any such payment being due by
Borrower to a Governmental Authority, 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) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which Borrower
is located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law and
reasonably requested by Borrower, such properly completed and executed
documentation prescribed by applicable law and reasonably requested by Borrower
or the Administrative Agent as will permit such payments to be made without
withholding or at a reduced rate; provided that such Lender is legally entitled
to complete, execute and deliver such documentation and in such Lender's
reasonable judgment such completion, execution or submission would not
materially prejudice the legal position of such Lender, would not subject such
Lender to any material unreimbursed cost and would not otherwise be
disadvantageous to such Lender in any way. Each Foreign Lender shall (i) furnish
either (a) two accurate and complete originally

                                      -50-
<PAGE>

executed U.S. Internal Revenue Service Form W-8BEN (or successor form) or (b) an
accurate and complete U.S. Internal Revenue Service Form W-8ECI (or successor
form), certifying, in either case, to such Foreign Lender's legal entitlement to
an exemption or reduction from U.S. federal withholding tax with respect to all
interest payments hereunder, and (ii) to the extent it may lawfully do so at
such times, upon reasonable request by Borrower or the Administrative Agent,
provide a new Form W-8BEN (or successor form) or Form W-8ECI (or successor form)
upon the expiration or obsolescence of any previously delivered form to
reconfirm any complete exemption from, or any entitlement to a reduction in,
U.S. federal withholding tax with respect to any interest payment hereunder;
provided that any Foreign Lender that is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Code shall also furnish a "Non-Bank Certificate" in
the form of Exhibit Q if it is furnishing a Form W-8BEN.

            (f) If the Administrative Agent or a Lender (or an assignee)
determines in its reasonable discretion that it has received a refund of any
Indemnified Taxes or Other Taxes as to which it has been indemnified by Borrower
or with respect to which Borrower has paid additional amounts pursuant to this
Section 2.15, it shall pay over such refund to Borrower (but only to the extent
of indemnity payments made, or additional amounts paid, by Borrower under this
Section 2.15 with respect to the Indemnified Taxes or the Other Taxes giving
rise to such refund), net of all out-of-pocket expenses of the Administrative
Agent or such Lender (or assignee) and without interest (other than any interest
paid by the relevant Governmental Authority with respect to such refund);
provided, however, that Borrower, upon the request of the Administrative Agent
or such Lender (or assignee), agrees to repay the amount paid over to Borrower
(plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to the Administrative Agent or such Lender (or assignee)
within a reasonable time (not to exceed 20 days) after receipt of written notice
that the Administrative Agent or such Lender (or assignee) is required to repay
such refund to such Governmental Authority. Nothing contained in this Section
2.15(f) shall require the Administrative Agent or any Lender (or assignee) to
make available its Tax Returns or any other information which it deems
confidential to Borrower or any other person. Notwithstanding anything to the
contrary, in no event will any Lender be required to pay any amount to Borrower
the payment of which would place such Lender in a less favorable net after-tax
position than such Lender would have been in if the additional amounts giving
rise to such refund of any Indemnified Taxes or Other Taxes had never been paid.

            SECTION 2.16 MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.

            (a) Mitigation of Obligations. If any Lender requests compensation
under Section 2.12, or if Borrower is required to pay any additional amount to
any Lender or any Governmental Authority for the account of any Lender pursuant
to Section 2.15, 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 reasonable judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section
2.12 or 2.15, 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. Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment. A certificate setting forth such costs and expenses
in reasonable detail submitted by such Lender to the Administrative Agent shall
be conclusive absent manifest error.

            (b) Replacement of Lenders. If any Lender requests compensation
under Section 2.12, or if Borrower is required to pay any additional amount to
any Lender or any Governmental Authority for the account of any Lender pursuant
to Section 2.15, or if any Lender defaults in its obligation to fund Loans
hereunder, then 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 11.04), all of its interests, rights and

                                      -51-
<PAGE>

obligations under this Agreement to an assignee selected by Borrower that shall
assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) Borrower shall have received the
prior written consent of the Administrative Agent (and, if a Revolving
Commitment is being assigned, the Issuing Bank and Swingline Lender), which
consents shall not unreasonably be withheld, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans
and participations in LC Disbursements and Swingline Loans, the principal amount
of their LC Facility Deposit, accrued interest thereon, accrued fees and all
other amounts payable to it hereunder (assuming for this purpose that the Loans
of such Lender were being prepaid) from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or Borrower (in the case of
all other amounts) and (iii) in the case of any such assignment resulting from a
claim for compensation under Section 2.12 or payments required to be made
pursuant to Section 2.15, such assignment will result in a material 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 Borrower to require such
assignment and delegation cease to apply.

            SECTION 2.17 SWINGLINE LOANS.

            (a) Swingline Commitment. Subject to the terms and conditions set
forth herein, the Swingline Lender agrees to make Swingline Loans to Borrower
from time to time during the Revolving Availability Period, in an aggregate
principal amount at any time outstanding that will not result in (i) the
aggregate principal amount of outstanding Swingline Loans exceeding $10.0
million or (ii) the sum of the total Revolving Exposures exceeding the total
Revolving Commitments; provided that the Swingline Lender shall not be required
to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the
foregoing limits and subject to the terms and conditions set forth herein,
Borrower may borrow, repay and reborrow Swingline Loans.

            (b) Swingline Loans. To request a Swingline Loan, Borrower shall
deliver, by hand delivery or telecopy, a duly completed and executed Borrowing
Request to the Administrative Agent and the Swingline Lender, not later than
2:00 p.m., New York City time, on the day of a proposed Swingline Loan. Each
such notice shall be irrevocable and shall specify the requested date (which
shall be a Business Day) and the amount of the requested Swingline Loan. Each
Swingline Loan shall be an ABR Loan. The Swingline Lender shall make each
Swingline Loan available to Borrower by means of a credit to the general deposit
account of Borrower with the Swingline Lender (or, in the case of a Swingline
Loan made to finance the reimbursement of a Revolving LC Disbursement as
provided in Section 2.18(e), by remittance to the Issuing Bank) by 3:00 p.m.,
New York City time, on the requested date of such Swingline Loan. Borrower shall
not request a Swingline Loan if at the time of or immediately after giving
effect to the Extension of Credit contemplated by such request a Default has
occurred and is continuing or would result therefrom. Swingline Loans shall be
made in minimum amounts of $500,000 and integral multiples of $100,000 above
such amount.

            (c) Prepayment. Borrower shall have the right at any time and from
time to time to repay any Swingline Loan, in whole or in part, upon giving
written notice to the Swingline Lender and the Administrative Agent before 12:00
noon, New York City time, on the proposed date of repayment.

            (d) Participations. The Swingline Lender may at any time in its
discretion by written notice given to the Administrative Agent (provided such
notice requirement shall not apply if the Swingline Lender and the
Administrative Agent are the same entity) not later than 11:00 a.m., New York
City time, on the next succeeding Business Day following such notice require the
Revolving Lenders to acquire participations on such Business Day in all or a
portion of the Swingline Loans then outstanding. Such notice shall specify the
aggregate amount of Swingline Loans in which Revolving Lenders will participate.
Promptly upon receipt of such notice, the Administrative Agent will give notice
thereof to each

                                      -52-
<PAGE>

Revolving Lender, specifying in such notice such Lender's Pro Rata Percentage of
such Swingline Loan or Loans. Each Revolving Lender hereby absolutely and
unconditionally agrees, upon receipt of notice as provided above, to pay to the
Administrative Agent, for the account of the Swingline Lender, such Lender's Pro
Rata Percentage of such Swingline Loan or Loans. Each Revolving Lender
acknowledges and agrees that its obligation to acquire participations in
Swingline Loans pursuant to this paragraph is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or reduction or termination of the Commitments, and
that each such payment shall be made without any offset, abatement, withholding
or reduction whatsoever (so long as such payment shall not cause such Lender's
Revolving Exposure to exceed such Lender's Revolving Commitment). Each Revolving
Lender shall comply with its obligation under this paragraph by wire transfer of
immediately available funds, in the same manner as provided in Section 2.02(c)
with respect to Loans made by such Lender (and Section 2.02 shall apply, mutatis
mutandis, to the payment obligations of the Revolving Lenders), and the
Administrative Agent shall promptly pay to the Swingline Lender the amounts so
received by it from the Revolving Lenders. The Administrative Agent shall notify
Borrower of any participations in any Swingline Loan acquired by the Revolving
Lenders pursuant to this paragraph, and thereafter payments in respect of such
Swingline Loan shall be made to the Administrative Agent and not to the
Swingline Lender. Any amounts received by the Swingline Lender from Borrower (or
other party on behalf of Borrower) in respect of a Swingline Loan after receipt
by the Swingline Lender of the proceeds of a sale of participations therein
shall be promptly remitted to the Administrative Agent. Any such amounts
received by the Administrative Agent shall be promptly remitted by the
Administrative Agent to the Revolving Lenders that shall have made their
payments pursuant to this paragraph, as their interests may appear. The purchase
of participations in a Swingline Loan pursuant to this paragraph shall not
relieve Borrower of any default in the payment thereof.

            SECTION 2.18 LETTERS OF CREDIT.

            (a) General. Subject to the terms and conditions set forth herein,
Borrower may request (i) the Issuing Bank, and the Issuing Bank agrees, to issue
Revolving Letters of Credit for its own account or the account of a Subsidiary
in a form reasonably acceptable to Borrower and the Administrative Agent and the
Issuing Bank, at any time and from time to time during the Revolving
Availability Period (provided that Borrower shall be a co-applicant, and be
jointly and severally liable, with respect to each Letter of Credit issued for
the account of a Subsidiary) and (ii) the LC Facility Issuing Bank, and the LC
Facility Issuing Bank agrees, to issue the LC Facility Letter of Credit for its
own account in a form reasonably acceptable to Borrower and the Administrative
Agent and the LC Facility Issuing Bank, on the Closing Date for the purpose of
providing credit support for certain Commodity Hedging Obligations. The Issuing
Bank or the LC Facility Issuing Bank, as applicable, shall have no obligation to
issue, and Borrower shall not request the issuance of, any Letter of Credit at
any time if after giving effect to such issuance, (i) the Revolving LC Exposure
would exceed the Revolving LC Commitment or the total Revolving Exposure would
exceed the total Revolving Commitments or (ii) the LC Facility LC Exposure would
exceed the LC Facility Deposit, as applicable. In the event of any inconsistency
between the terms and conditions of this Agreement and the terms and conditions
of any form of letter of credit application or other agreement submitted by
Borrower to, or entered into by Borrower with, the Issuing Bank or the LC
Facility Issuing Bank, as applicable, relating to any Letter of Credit, the
terms and conditions of this Agreement shall control.

            (b) Request for Issuance, Amendment, Renewal, Extension; Certain
Conditions. To request the issuance of a Letter of Credit or the amendment,
renewal or extension of an outstanding Letter of Credit, Borrower shall hand
deliver or telecopy (or transmit by electronic communication, if arrangements
for doing so have been approved by the Issuing Bank or the LC Facility Issuing
Bank, as applicable) an LC Request to the Issuing Bank or the LC Facility
Issuing Bank, as applicable, and the Administrative Agent not later than 11:00
a.m. on the third Business Day preceding the requested date of issuance,

                                      -53-
<PAGE>

amendment, renewal or extension (or such later date and time as is acceptable to
the Issuing Bank or the LC Facility Issuing Bank, as applicable).

            A request for an initial issuance of a Letter of Credit shall
specify in form and detail satisfactory to the Issuing Bank:

            (i) the proposed issuance date of the requested Letter of Credit
      (which shall be a Business Day) provided that with respect to the LC
      Facility Letter of Credit the issue date shall be the Closing Date;

            (ii) the amount thereof provided that with respect to the LC
      Facility Letter of Credit the amount shall be $15.0 million;

            (iii) the expiry date thereof (which shall not be later than the
      close of business on the Letter of Credit Expiration Date);

            (iv) the name and address of the beneficiary thereof;

            (v) whether the Letter of Credit is to be issued for its own account
      or for the account of one of its Subsidiaries (provided that Borrower
      shall be a co-applicant, and therefore jointly and severally liable, with
      respect to each Letter of Credit issued for the account of a Subsidiary);

            (vi) the documents to be presented by such beneficiary in connection
      with any drawing thereunder;

            (vii) the full text of any certificate to be presented by such
      beneficiary in connection with any drawing thereunder; and

            (viii) such other matters as the Issuing Bank or the LC Facility
      Issuing Bank, as applicable, may reasonably require.

            A request for an amendment, renewal or extension of any outstanding
Letter of Credit shall specify in form and detail satisfactory to the Issuing
Bank or the LC Facility Issuing Bank, as the case may be:

            (i) the Letter of Credit to be amended, renewed or extended;

            (ii) the proposed date of amendment, renewal or extension thereof
      (which shall be a Business Day);

            (iii) the nature of the proposed amendment, renewal or extension;
      and

            (iv) such other matters as the Issuing Bank or the LC Facility
      Issuing Bank, as applicable, may reasonably require.

If requested by the Issuing Bank or the LC Facility Issuing Bank, as applicable,
Borrower also shall submit a letter of credit application on the Issuing Bank's
or the LC Facility Issuing Bank's, as applicable, standard form in connection
with any request for a Letter of Credit. A Letter of Credit shall be issued,
amended, renewed or extended only if (and, upon issuance, amendment, renewal or
extension of each Letter of Credit, Borrower shall be deemed to represent and
warrant that), after giving effect to such issuance, amendment, renewal or
extension, (i) with respect to Revolving Letters of Credit, the Revolving LC

                                      -54-
<PAGE>

Exposure shall not exceed the Revolving LC Commitment, (ii) with respect to
Revolving Letters of Credit, the total Revolving Exposures shall not exceed the
total Revolving Commitments, (iii) with respect to the LC Facility Letter of
Credit, the LC Facility LC Exposure shall not exceed the Total LC Facility
Deposit, and (iv) the conditions set forth in Article IV in respect of any such
issuance, amendment, renewal or extension shall have been satisfied. In the case
of a Revolving Letter of Credit, unless the Issuing Bank shall agree otherwise,
no Revolving Letter of Credit shall be in an initial amount less than $20,000.

            (c) Expiration Date. Each Revolving Letter of Credit shall expire at
or prior to the close of business on the earlier of (x) the date which is one
year after the date of the issuance of such Letter of Credit (or, in the case of
any renewal or extension thereof, one year after such renewal or extension) and
(y) the Letter of Credit Expiration Date. The LC Facility Letter of Credit shall
expire on the Letter of Credit Expiration Date.

            (d) Participations. (i) By the issuance of a Revolving Letter of
Credit (or an amendment to a Revolving Letter of Credit increasing the amount
thereof) and without any further action on the part of the Issuing Bank or the
Lenders, the Issuing Bank hereby irrevocably grants to each Revolving Lender,
and each Revolving Lender hereby acquires from the Issuing Bank, a participation
in such Revolving Letter of Credit equal to such Revolving Lender's Pro Rata
Percentage of the aggregate amount available to be drawn under such Revolving
Letter of Credit. In consideration and in furtherance of the foregoing, each
Revolving Lender hereby absolutely and unconditionally agrees to pay to the
Administrative Agent, for the account of the Issuing Bank, such Revolving
Lender's Pro Rata Percentage of each Revolving LC Disbursement made by the
Issuing Bank and not reimbursed by Borrower on the date due as provided in
Section 2.18(e), or of any reimbursement payment required to be refunded to
Borrower for any reason. Each Revolving Lender acknowledges and agrees that its
obligation to acquire participations pursuant to this paragraph in respect of
Revolving Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including any amendment, renewal or
extension of any Revolving Letter of Credit or the occurrence and continuance of
a Default or reduction or termination of the Commitments, and that each such
payment shall be made without any offset, abatement, withholding or reduction
whatsoever.

            (ii) By the issuance of an LC Facility Letter of Credit without any
further action on the part of the LC Facility Issuing Bank or the LC Facility
Lenders, the LC Facility Issuing Bank hereby grants to each LC Facility Lender,
and each LC Facility Lender hereby acquires from the LC Facility Issuing Bank, a
participation in each LC Facility Letter of Credit equal to such LC Facility
Lender's Pro Rata Percentage of the aggregate amount available to be drawn under
such LC Facility Letter of Credit. The aggregate purchase price for the
participations of each LC Facility Lender in LC Facility Letters of Credit shall
equal the amount of the LC Facility Deposit of such LC Facility Lender. Each LC
Facility Lender shall pay to the Administrative Agent its LC Facility Deposit in
full on the Closing Date. Each LC Facility Lender hereby absolutely and
unconditionally agrees that if the LC Facility Issuing Bank makes an LC Facility
LC Disbursement which is not reimbursed by Borrower on the date due as provided
in paragraph (e) of this Section 2.18, or is required to refund any
reimbursement payment in respect of an LC Facility LC Disbursement to Borrower
for any reason, the Administrative Agent shall reimburse the LC Facility Issuing
Bank for the amount of such LC Facility LC Disbursement from each LC Facility
Lender's LC Facility Deposit invested in the LC Facility Deposit Account in
proportion to their respective LC Facility Pro Rata Percentages. In the event
the LC Facility Deposit Account is charged by the Administrative Agent to
reimburse the LC Facility Issuing Bank for an unreimbursed LC Facility LC
Disbursement, Borrower shall have the right, at any time prior to the LC
Facility Maturity Date, to pay over to the Administrative Agent in reimbursement
thereof an amount equal to the amount so charged, and such payment shall be
invested by the Administrative Agent in the LC Facility Deposit Account. Each LC
Facility Lender acknowledges and agrees that its authorization granted hereby
and obligations

                                      -55-
<PAGE>

hereunder are unconditional and irrevocable and shall not be affected by any
circumstance whatsoever, including any amendment, renewal or extension of any LC
Facility Letter of Credit or the occurrence and continuance of a Default or the
return of the LC Facility Deposits and that each such payment shall be made
without any offset, abatement, withholding or reduction whatsoever. Without
limiting the foregoing, each LC Facility Lender irrevocably authorizes the
Administrative Agent to apply amounts of its LC Facility Deposit as provided in
this subparagraph (ii).

            (e) Reimbursement. (i) If the Issuing Bank or the LC Facility
Issuing Bank, as applicable, shall make any LC Disbursement in respect of a
Letter of Credit, Borrower shall reimburse such LC Disbursement by paying to the
Issuing Bank or the LC Facility Issuing Bank, as applicable, an amount equal to
such LC Disbursement not later than 3:00 p.m., New York City time, on the date
that such LC Disbursement is made if Borrower shall have received notice of such
LC Disbursement prior to 11:00 a.m., New York City time, on such date, or, if
such notice has not been received by Borrower prior to such time on such date,
then not later than 3:00 p.m., New York City time, on the Business Day
immediately following the day that Borrower receives such notice; provided that
Borrower may, subject to the conditions to borrowing set forth herein, request
in accordance with Section 2.03 that such payment (i) in respect of a Revolving
LC Disbursement be financed with ABR Revolving Loans in an equivalent amount
and, to the extent so financed, Borrower's obligation to make such payment shall
be discharged and replaced by the resulting ABR Revolving Loans or (ii) in
respect of an LC Facility LC Disbursement be financed with ABR Term Loans in an
equivalent amount and, to the extent so financed, Borrower's obligation to make
such payment shall be discharged and replaced by the resulting ABR Term Loans.

            (ii) If Borrower fails to make payment due under paragraph (i) above
with respect to a Revolving Letter of Credit when due, the Issuing Bank shall
notify the Administrative Agent and the Administrative Agent shall notify each
Revolving Lender of the applicable Revolving LC Disbursement, the payment then
due from Borrower in respect thereof and such Revolving Lender's Pro Rata
Percentage thereof. Each Revolving Lender shall pay by wire transfer of
immediately available funds to the Administrative Agent not later than 2:00
p.m., New York City time, on such date (or, if such Revolving Lender shall have
received such notice later than 12:00 noon, New York City time, on any day, not
later than 11:00 a.m., New York City time, on the immediately following Business
Day), an amount equal to such Revolving Lender's Pro Rata Percentage of the
unreimbursed Revolving LC Disbursement in the same manner as provided in Section
2.02(c) with respect to Revolving Loans made by such Revolving Lender, and the
Administrative Agent will promptly pay to the Issuing Bank the amounts so
received by it from the Revolving Lenders. The Administrative Agent will
promptly pay to the Issuing Bank any amounts received by it from Borrower
pursuant to the above paragraph prior to the time that any Revolving Lender
makes any payment pursuant to the preceding sentence and any such amounts
received by the Administrative Agent from Borrower thereafter will be promptly
remitted by the Administrative Agent to the Revolving Lenders that shall have
made such payments and to the Issuing Bank, as appropriate.

            (iii) If Borrower fails to make any payment when due under paragraph
(i) with respect to an LC Facility Letter of Credit when due, the LC Facility
Issuing Bank shall notify the Administrative Agent and the Administrative Agent
shall notify each LC Facility Lender of the applicable LC Facility LC
Disbursement, the payment then due from Borrower in respect thereof and such LC
Facility Lender's Pro Rata Percentage thereof. The Administrative Agent will
promptly pay to the LC Facility Issuing Bank each LC Facility Lender's Pro Rata
Percentage of such LC Facility LC Disbursement from such LC Facility Lender's LC
Facility Deposit. Promptly following receipt by the Administrative Agent of any
payment by Borrower in respect of any LC Facility LC Disbursement, the
Administrative Agent shall distribute such payment to the LC Facility Issuing
Bank or, to the extent payments have been made from the LC Facility Deposits, to
the LC Facility Deposit Account to be added to the LC Facility Deposits of the
LC Facility Lenders in accordance with their respective Pro Rata Percentages.

                                      -56-
<PAGE>

            (iv) If any Revolving Lender shall not have made its Pro Rata
Percentage of such Revolving LC Disbursement available to the Administrative
Agent as provided above, each of such Revolving Lender and Borrower severally
agrees to pay interest on such amount, for each day from and including the date
such amount is required to be paid in accordance with the foregoing to but
excluding the date such amount is paid, to the Administrative Agent for the
account of the Issuing Bank at (i) in the case of Borrower, the rate per annum
set forth in Section 2.18(h) and (ii) in the case of such Lender, at a rate
determined by the Administrative Agent in accordance with banking industry rules
or practices on interbank compensation.

            (f) Obligations Absolute. The Reimbursement Obligation of Borrower
as provided in Section 2.18(e) shall be absolute, unconditional and irrevocable,
and shall be paid and performed strictly in accordance with the terms of this
Agreement under any and all circumstances whatsoever and irrespective of (i) any
lack of validity or enforceability of any Letter of Credit or this Agreement, or
any term or provision therein; (ii) any draft or other document presented under
a Letter of Credit being proved to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; (iii) payment by the Issuing Bank or LC Facility Issuing Bank,
as applicable, under a Letter of Credit against presentation of a draft or other
document that fails to comply with the terms of such Letter of Credit; (iv) any
other event or circumstance whatsoever, whether or not similar to any of the
foregoing, that might, but for the provisions of this Section 2.18, constitute a
legal or equitable discharge of, or provide a right of setoff against, the
obligations of Borrower hereunder; (v) the fact that a Default shall have
occurred and be continuing; or (vi) an event or events that has or could
reasonably be expected to result in any material adverse change to the business,
property, results of operations or condition, financial or otherwise, of
Borrower and its Subsidiaries. None of the Agents, the Lenders, the Issuing
Bank, the LC Facility Issuing Bank or any of their Affiliates shall have any
liability or responsibility by reason of or in connection with the issuance or
transfer of any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), or any error, omission, interruption, loss or delay in
transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a
drawing thereunder), any error in interpretation of technical terms or any
consequence arising from causes beyond the control of the Issuing Bank or LC
Facility Issuing Bank, as applicable; provided that nothing in this Section
2.18(f) shall be construed to excuse the Issuing Bank or LC Facility Issuing
Bank, as applicable, from liability to Borrower to the extent of any direct
damages (as opposed to consequential damages, claims in respect of which are
hereby waived by Borrower to the extent permitted by applicable law) suffered by
Borrower that are caused by the Issuing Bank's or the LC Facility Issuing
Bank's, as applicable, failure to exercise care when determining whether drafts
and other documents presented under a Letter of Credit comply with the terms
thereof. The parties hereto expressly agree that, in the absence of gross
negligence or willful misconduct on the part of the Issuing Bank or LC Facility
Issuing Bank, as applicable (as finally determined by a court of competent
jurisdiction), the Issuing Bank or LC Facility Issuing Bank, as applicable,
shall be deemed to have exercised care in each such determination. In
furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
Issuing Bank or LC Facility Issuing Bank, as applicable, may, in its sole
discretion, either accept and make payment upon such documents without
responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

            (g) Disbursement Procedures. The Issuing Bank or the LC Facility
Issuing Bank, as applicable, shall, promptly following its receipt thereof,
examine all documents purporting to represent a demand for payment under a
Letter of Credit. The Issuing Bank or the LC Facility Issuing Bank, as
applicable, shall promptly give written notice to the Administrative Agent and
Borrower of such demand for

                                      -57-
<PAGE>

payment and whether the Issuing Bank or the LC Facility Issuing Bank, as
applicable, has made or will make an LC Disbursement thereunder; provided that
any failure to give or delay in giving such notice shall not relieve Borrower of
its Reimbursement Obligation to the Issuing Bank or the LC Facility Issuing
Bank, as applicable, and the Revolving Lenders and the LC Facility Lenders with
respect to any such LC Disbursement (other than with respect to the timing of
such Reimbursement Obligation set forth in Section 2.18(e)).

            (h) Interim Interest. If the Issuing Bank or the LC Facility Issuing
Bank, as applicable, shall make any LC Disbursement, then, unless Borrower shall
reimburse such LC Disbursement in full on the date such LC Disbursement is made,
the unpaid amount thereof shall bear interest payable on demand, for each day
from and including the date such LC Disbursement is made to but excluding the
date that Borrower reimburses such LC Disbursement, at the rate per annum
determined pursuant to Section 2.06(c). Interest accrued pursuant to this
paragraph shall be for the account of the Issuing Bank or the LC Facility
Issuing Bank, as applicable, except that interest accrued on and after the date
of payment by any Revolving Lender or LC Facility Lender pursuant to Section
2.18(e) to reimburse the Issuing Bank or the LC Facility Issuing Bank, as
applicable, shall be for the account of such Lender to the extent of such
payment.

            (i) Cash Collateralization. If any Event of Default shall occur and
be continuing, on the Business Day that Borrower receives notice from the
Administrative Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, in the case of Revolving Letters of Credit, Revolving
Lenders with Revolving LC Exposure representing greater than 50% of total
Revolving LC Exposure or in the case of LC Facility Letters of Credit, LC
Facility Lenders with LC Facility LC Exposure representing greater than 50% of
total LC Facility LC Exposure) demanding the deposit of cash collateral pursuant
to this paragraph, Borrower shall deposit in the LC Sub-Account, in the name of
the Collateral Agent and for the benefit of the Revolving Lenders and LC
Facility Lenders, as applicable, an amount in cash equal to the LC Exposure as
of such date plus any accrued and unpaid interest thereon; provided that the
obligation to deposit such cash collateral shall become effective immediately,
and such deposit shall become immediately due and payable, without demand or
other notice of any kind, upon the occurrence of any Event of Default with
respect to Borrower described in paragraph (g) or (h) of Article VIII. Funds in
the LC Sub-Account shall be applied by the Collateral Agent to reimburse the
Issuing Bank or the LC Facility Issuing Bank, as applicable, for LC
Disbursements for which it has not been reimbursed and, to the extent not so
applied, shall be held for the satisfaction of outstanding Reimbursement
Obligations or, if the maturity of the Loans has been accelerated (but subject
to the consent of the Revolving Lenders and LC Facility Lenders with LC Exposure
representing greater than 50% of such class's total LC Exposure), be applied to
satisfy other Obligations of Borrower under this Agreement. If Borrower is
required to provide an amount of cash collateral hereunder as a result of the
occurrence of an Event of Default, such amount plus any accrued interest or
realized profits with respect to such amounts (to the extent not applied as
aforesaid) shall be returned to Borrower within three Business Days after all
Events of Default have been cured or waived.

            (j) Additional Issuing Banks. Borrower may, at any time and from
time to time, designate one or more additional Revolving Lenders to act as an
Issuing Bank under the terms of this Agreement, with the consent of the
Administrative Agent (which consent shall not be unreasonably withheld), the
Issuing Bank and such Revolving Lender(s). Any Lender designated as an Issuing
Bank pursuant to this paragraph (j) shall be deemed (in addition to being a
Revolving Lender) to be the Issuing Bank with respect to Letters of Credit
issued or to be issued by such Revolving Lender, and all references herein and
in the other Loan Documents to the term "Issuing Bank" shall, with respect to
such Letters of Credit, be deemed to refer to such Revolving Lender in its
capacity as Issuing Bank, as the context shall require.

            (k) Resignation or Removal of the Issuing Bank. (i) The Issuing Bank
may resign as Issuing Bank hereunder at any time upon at least 30 days' prior
notice to the Lenders, the Administrative Agent and Borrower. The Issuing Bank
may be replaced at any time by written agreement among Borrower, each Agent, the
replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent
shall notify the Lenders of any such replacement of the Issuing Bank or any such
additional Issuing Bank. At the time any such resignation or replacement shall
become effective, Borrower shall pay all unpaid fees accrued for the account of
the replaced Issuing Bank pursuant to Section 2.05(c). From and after the
effective date of any such resignation or replacement or addition, as
applicable, (i) the successor or additional 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 by it thereafter and (ii) references herein to
the term "Issuing Bank" shall be deemed to refer to such successor or such
addition or to any previous Issuing Bank, or to such successor or such addition
and all previous Issuing Banks, as the context shall require. After the
resignation or replacement of an Issuing Bank hereunder, the replaced Issuing
Bank shall remain a party hereto and shall continue to have all the rights and
obligations of an Issuing Bank under this Agreement with respect to Letters of
Credit issued by it prior to such resignation or replacement, but shall not be
required to issue additional Letters of Credit. If at any time there is more
than one Issuing Bank hereunder, Borrower may, in its discretion, select which
Issuing Bank is to issue any particular Letter of Credit.

            (i) Resignation or Removal of the LC Facility Issuing Bank. The LC
Facility Issuing Bank may resign as LC Facility Issuing Bank hereunder at any
time upon at least 30 days' prior notice to the Lenders, the Administrative
Agent and Borrower. The LC Facility Issuing Bank may be replaced at any time by
written agreement among Borrower, each Agent, the replaced LC Facility Issuing
Bank and the successor LC Facility Issuing Bank. The Administrative Agent shall
notify the Lenders of any such replacement of the LC Facility Issuing Bank or
any such additional LC Facility Issuing Bank. At the time any such resignation
or replacement shall become effective, Borrower shall pay all unpaid fees
accrued for the account of the replaced LC Facility Issuing Bank pursuant to
Section 2.05(d). From and after the effective date of any such resignation or
replacement or addition, as applicable, (i) the successor or additional LC
Facility Issuing Bank shall have all the rights and obligations of the LC
Facility Issuing Bank under this Agreement with respect to LC Facility Letters
of Credit and (ii) references herein to the term "LC Facility Issuing Bank"
shall be deemed to refer to such successor or such addition or to any previous
LC Facility Issuing Bank, or to such successor or such addition and all previous
LC Facility Issuing Banks, as the context shall require. After the resignation
or replacement of the LC Facility Issuing Bank hereunder, the replaced LC
Facility Issuing Bank shall remain a party hereto and shall continue to have all
the rights and obligations of an LC Facility Issuing Bank under this Agreement
with respect to LC Facility Letters of Credit issued by it prior to such
resignation or replacement, but shall not be required to issue additional LC
Facility Letters of Credit.

            (l) Other. The Issuing Bank or the LC Facility Issuing Bank, as
applicable, shall be under no obligation to issue any Letter of Credit if

            (i) any order, judgment or decree of any Governmental Authority or
      arbitrator shall by its terms purport to enjoin or restrain the Issuing
      Bank or the LC Facility Issuing Bank, as applicable, from issuing such
      Letter of Credit, or any law applicable to the Issuing Bank or the LC
      Facility Issuing Bank, as applicable, or any request or directive (whether
      or not having the force of law) from any Governmental Authority with
      jurisdiction over the Issuing Bank or the LC Facility Issuing Bank, as
      applicable, shall prohibit, or request that the Issuing Bank or the LC
      Facility Issuing Bank, as applicable, refrain from, the issuance of
      letters of credit generally or such Letter of Credit in particular or
      shall impose upon the Issuing Bank or the LC Facility Issuing Bank, as
      applicable, with respect to such Letter of Credit any restriction, reserve
      or capital requirement (for which the Issuing Bank or the LC Facility
      Issuing Bank, as applicable, is not oth-

                                      -59-
<PAGE>

      erwise compensated hereunder) not in effect on the Closing Date, or shall
      impose upon the Issuing Bank or the LC Facility Issuing Bank, as
      applicable, any unreimbursed loss, cost or expense which was not
      applicable on the Closing Date and which the Issuing Bank or the LC
      Facility Issuing Bank, as applicable, in good faith deems material to it;
      or

            (ii) the issuance of such Letter of Credit would violate one or more
      policies of the Issuing Bank or the LC Facility Issuing Bank, as
      applicable.

The Issuing Bank or the LC Facility Issuing Bank, as applicable, shall be under
no obligation to amend any Letter of Credit if (A) the Issuing Bank, as
applicable, would have no obligation at such time to issue such Revolving Letter
of Credit in its amended form under the terms hereof, or (B) the beneficiary of
such Letter of Credit does not accept the proposed amendment to such Letter of
Credit.

            SECTION 2.19 LC FACILITY DEPOSIT ACCOUNT. (a) The LC Facility
Deposits shall be held in escrow by UBS AG, Stamford Branch, as escrow agent,
subject to disbursement in accordance with the terms of Sections 2.07, 2.18 and
this Section 2.19, in the LC Facility Deposit Account, and no party other than
UBS AG, Stamford Branch shall have a right of withdrawal from the LC Facility
Deposit Account or any other right or power with respect to the LC Facility
Deposits, except as expressly set forth in Section 2.07. Notwithstanding any
provision in this Agreement to the contrary, the sole funding obligation of each
LC Facility Lender in respect of its participation in LC Facility Letters of
Credit shall be satisfied in full upon the funding of its LC Facility Deposit on
the Closing Date.

            (b) Each of Borrower, the Administrative Agent, the LC Facility
Issuing Bank issuing the LC Facility Letter of Credit and each LC Facility
Lender hereby acknowledges and agrees that each LC Facility Lender is funding
its LC Facility Deposit to the Administrative Agent for application in the
manner contemplated by Section 2.18 and that the Administrative Agent has agreed
to invest the LC Facility Deposits (except during periods when, and to the
extent to which, such LC Facility Deposits are used to cover unreimbursed LC
Facility LC Disbursements for the LC Facility Lenders) and pay to the LC
Facility Lenders (i) the rate for one month LIBOR deposits (the "BENCHMARK LIBOR
RATE") minus (ii) 0.125% (such 0.125% being the "COST AMOUNT"). The Cost Amount
will be subject to annual review and adjustment by UBS AG Stamford Branch, in
light of then prevailing market conditions. Such interest will be paid to the LC
Facility Lenders by the Administrative Agent quarterly in arrears when LC
Facility LC Fees are payable pursuant to Section 2.05. In addition to the
foregoing payments by the Administrative Agent, Borrower agrees to make payments
to the LC Facility Lenders quarterly in arrears when LC Facility LC Fees are
payable pursuant to Section 2.05 (and together with the payment of such fees) in
an amount equal to the Cost Amount.

            (c) Neither Borrower nor any other Loan Party shall have any right,
title or interest in or to the LC Facility Deposits and no obligations with
respect thereto (except for the reimbursement obligations provided in Section
2.18), it being acknowledged and agreed by the parties hereto that the making of
the LC Facility Deposits by the LC Facility Lenders, the provisions of this
Section 2.19 and the application of the LC Facility Deposits in the manner
contemplated by Section 2.18(b) constitute agreements among the Administrative
Agent, the LC Facility Issuing Bank issuing any LC Facility Letter of Credit and
each LC Facility Lender with respect to the funding obligations of each LC
Facility Lender in respect of its participation in LC Facility Letters of Credit
and do not constitute any loan or extension of credit to the Borrower.
Notwithstanding anything in the preceding sentence to the contrary and if,
notwithstanding the intent of the parties to this Agreement, the LC Facility
Deposits are deemed to be an asset of a Loan Party, each Loan Party shall be
deemed to have granted to the Administrative Agent, as of the Closing Date, for
the sole and exclusive benefit of the LC Facility Issuing Bank and the LC
Facility Lenders, a first priority security interest in and lien upon the LC
Facility Deposit Account and all funds deposited therein.

                                      -60-
<PAGE>

            (d) The Administrative Agent shall return any remaining LC Facility
Deposits to the LC Facility Lenders on the LC Facility Maturity Date. If at any
time there exists Excess LC Facility Deposits, the Administrative Agent shall
upon the written request of the Borrower distribute each LC Facility Lender's
pro rata share of the amount of such excess and the LC Facility Deposit Account
shall be reduced by such amount. Once distributed, amounts previously deposited
in the LC Facility Deposit Account will not be redeposited and the LC Facility
LC Exposure shall thereafter not exceed the new balance in the LC Facility
Deposit Account.

            (e) If the Administrative Agent is advised that deposits (in the
applicable amounts) are not being offered in the London interbank market, or the
Administrative Agent determines that adequate and fair means do not otherwise
exist for ascertaining the Benchmark LIBOR Rate, then the LC Facility Deposits
shall be invested so as to earn a return equal to (i) the greater of the Federal
Funds Effective Rate and a rate determined by the Administrative Agent in
accordance with banking industry rules on interbank compensation (ii) minus the
Cost Amount. In addition, the Borrower shall reimburse the Administrative Agent
for any breakage or other losses or expenses incurred by it in connection with
the termination of the LC Facility Deposits (and the related termination of the
investment of the funds held in the LC Facility Deposit Account) prior to any
scheduled investment termination date (which will be in one-month LIBOR periods
unless otherwise agreed).

            (f) If the Administrative Agent from time to time withdraws any
amounts from the LC Facility Deposit Account in accordance with the terms of
this Agreement, other than to reimburse the LC Facility Issuing Bank pursuant to
Section 2.18(e)(iii), such amounts shall be distributed by the Administrative
Agent to each LC Facility Lender in accordance with such LC Facility Lender's
Pro Rata Percentage with respect to the LC Facility Deposits.

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

            Each Loan Party represents and warrants to the Administrative Agent,
the Collateral Agent, the Issuing Bank and each of the Lenders (with references
to the Companies being references thereto after giving effect to the
Transactions unless otherwise expressly stated) that:

            SECTION 3.01 ORGANIZATION; POWERS. Each Company (a) is duly
organized and validly existing under the laws of the jurisdiction of its
organization, (b) has all requisite power and authority to carry on its business
as now conducted and to own and lease its property and (c) is qualified and in
good standing (to the extent such concept is applicable in the applicable
jurisdiction) to do business in every jurisdiction where such qualification is
required, except in such jurisdictions where the failure to so qualify or be in
good standing, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. There is no existing default
under any Organizational Document of any Company or any event which, with the
giving of notice or passage of time or both, would constitute a default by any
party thereunder.

            SECTION 3.02 AUTHORIZATION; ENFORCEABILITY. The Transactions to be
entered into by each Loan Party are within such Loan Party's powers and have
been duly authorized by all necessary action on the part of such Loan Party.
This Agreement has been duly executed and delivered by each Loan Party and
constitutes, and each other Loan Document to which any Loan Party is to be a
party, when executed and delivered by such Loan Party, will constitute, a legal,
valid and binding obligation of such Loan Party, enforceable in accordance with
its terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors' rights generally and subject to
general principles of equity, regardless of whether considered in a proceeding
in equity or at law.

                                      -61-
<PAGE>

            SECTION 3.03 NO CONFLICTS. Except as set forth on Schedule 3.03, the
Transactions (a) do not require any consent or approval of, registration or
filing with, or any other action by, any Governmental Authority, except (i) such
as have been obtained or made and are in full force and effect, (ii) filings
necessary to perfect Liens created by the Loan Documents and (iii) consents,
approvals, registrations, filings, permits or actions the failure to obtain or
perform which could not reasonably be expected to result in a Material Adverse
Effect, (b) will not violate the Organizational Documents of any Company or any
judgment, decree or order of any Governmental Authority, (c) will not violate or
result in a default or require any consent or approval under any indenture,
agreement, Organizational Document or other instrument binding upon any Company
or its property, or give rise to a right thereunder to require any payment to be
made by any Company that could reasonably be expected to result in a Material
Adverse Effect, and (d) will not result in the creation or imposition of any
Lien on any property of any Company, except Liens created by the Loan Documents
and Permitted Liens.

            SECTION 3.04 FINANCIAL STATEMENTS; PROJECTIONS. (a) Borrower has
heretofore delivered to the Lenders the (i) consolidated balance sheet of
Borrower as of February 29, 2004, audited by and accompanied by the unqualified
opinion of Murrell, Hall, McIntosh & Co., PLLP, independent public accountants,
certified by the chief financial officer of Borrower. Such financial statement
and all financial statements delivered pursuant to Sections 5.01(a), (b) and (c)
have been prepared in accordance with GAAP and fairly present in all material
respects the financial condition and results of operations and cash flows of
Borrower as of the dates and for the periods to which they relate. Except as set
forth in such financial statements, there are no liabilities of any Company of
any kind, whether accrued, contingent, absolute, determined, determinable or
otherwise, which could reasonably be expected to result in a Material Adverse
Effect, and there is no existing condition, situation or set of circumstances
which could reasonably be expected to result in such a Material Adverse Effect,
other than liabilities under the Loan Documents.

            (b) Borrower has heretofore delivered to the Lenders Borrower's
unaudited consolidated balance sheet and statements of income and cash flows and
EBITDA and other operating data as of and for the period December 23, 2003 to
February 29, 2004.

            (c) Borrower has heretofore delivered to the Lenders forecasts of
the financial performance of Borrower and its Subsidiaries for the period
February 29, 2004 to February 28, 2010.

            (d) The forecasts of financial performance of Borrower and its
Subsidiaries furnished to the Lenders have been prepared in good faith by
Borrower and based on assumptions believed by Borrower to be reasonable as of
the Closing Date.

            (e) Since February 29, 2004 there has been no event, change,
circumstance or occurrence that, individually or in the aggregate, has had or
could reasonably be expected to result in a Material Adverse Effect.

            SECTION 3.05 PROPERTIES. (a) Except as set forth on Schedule 3.05,
each Company has good title to, or valid leasehold interests in, all its
property material to its business, free and clear of all Liens except for, in
the case of Collateral, Permitted Collateral Liens and, in the case of all other
material property, Permitted Liens and minor irregularities or deficiencies in
title that, individually or in the aggregate, do not interfere with its ability
to conduct its business as currently conducted or to utilize such property for
its intended purpose. The property of the Companies, taken as a whole, (i) is in
good operating order, condition and repair (ordinary wear and tear excepted),
except to the extent that the failure to be in such condition could not
reasonably be expected to result in a Material Adverse Effect, and (ii)
constitutes all the property which is required for the business and operations
of the Companies as presently conducted.

                                      -62-
<PAGE>

            (b) Schedule 3.05(b) contains a true and complete list of each
interest in Real Property with a value of over $500,000 (i) owned by any Company
as of the date hereof and describes the type of interest therein held by such
Company and (ii) leased, subleased or otherwise occupied or utilized by any
Company, as lessee, sublessee, franchisee or licensee, as of the date hereof and
describes the type of interest therein held by such Company and whether such
lease, sublease or other instrument requires the consent of the landlord
thereunder or other parties thereto to the Transactions.

            (c) No Company has received any notice of, nor has any knowledge of,
the occurrence or pendency or contemplation of any Casualty Event affecting all
or any portion of its property. No Mortgage encumbers improved Real Property
that is located in an area that has been identified by the Secretary of Housing
and Urban Development as an area having special flood hazards within the meaning
of the National Flood Insurance Act of 1968 unless flood insurance available
under such Act has been obtained in accordance with Section 5.04.

            (d) Each Company owns or has rights to use all of the Collateral and
all rights with respect to any of the foregoing used in, necessary for or
material to each Company's business as currently conducted. The use by each
Company of such Collateral and all such rights with respect to the foregoing do
not infringe on the rights of any person other than such infringement which
could not, individually or in the aggregate, reasonably be expected to result in
a Material Adverse Effect. No claim has been made and remains outstanding that
any Company's use of any Collateral does or may violate the rights of any third
party that could, individually or in the aggregate, reasonably be expected to
result in a Material Adverse Effect.

            (e) The Equipment of each Company is in good repair, working order
and condition, reasonable wear and tear excepted. Each Company shall cause the
Equipment to be maintained and preserved in good repair, working order and
condition, reasonable wear and tear excepted, and shall as quickly as
commercially practicable make or cause to be made all repairs, replacements and
other improvements which are necessary or appropriate in the conduct of each
Company's business.

            SECTION 3.06 INTELLECTUAL PROPERTY.

            (a) Ownership/No Claims. Each Loan Party owns, or is licensed to
use, all patents, patent applications, trademarks, trade names, servicemarks,
copyrights, technology, trade secrets, proprietary information, domain names,
know-how and processes necessary for the conduct of its business as currently
conducted (the "INTELLECTUAL PROPERTY"), except for those the failure to own or
license which, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No claim has been asserted and
is pending by any person challenging or questioning the use of any such
Intellectual Property or the validity or effectiveness of any such Intellectual
Property, nor does any Loan Party know of any valid basis for any such claim.
The use of such Intellectual Property by each Loan Party does not infringe the
rights of any person, except for such claims and infringements that,
individually or in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect.

            (b) Registrations. Except pursuant to licenses and other user
agreements entered into by each Loan Party in the ordinary course of business
that are listed in Schedules 14(a) and 14(b) to the Perfection Certificate, on
and as of the date hereof (i) each Loan Party owns and possesses the right to
use, and has done nothing to authorize or enable any other person to use, any
copyright, patent or trademark (as such terms are defined in the Security
Agreement) listed in Schedules 14(a) and 14(b) to the Perfection Certificate and
(ii) all registrations listed in Schedules 14(a) and 14(b) to the Perfection
Certificate are valid and in full force and effect.

                                      -63-
<PAGE>

            (c) No Violations or Proceedings. To each Loan Party's knowledge, on
and as of the date hereof, there is no material violation by others of any right
of such Loan Party with respect to any copyright, patent or trademark listed in
Schedules 14(a) and 14(b) to the Perfection Certificate, respectively, pledged
by it under the name of such Loan Party except as may be set forth on Schedule
3.06(c).

            SECTION 3.07 EQUITY INTERESTS AND SUBSIDIARIES. (a) Schedule 3.07(a)
sets forth a list of (i) all the Subsidiaries of Borrower and their jurisdiction
of organization as of the Closing Date and (ii) the number of each class of its
Equity Interests authorized, and the number outstanding, on the Closing Date and
the number of shares covered by all outstanding options, warrants, rights of
conversion or purchase and similar rights at the Closing Date. All Equity
Interests of each Company are duly and validly issued and are fully paid and
non-assessable, and, other than the Equity Interests of Borrower, are owned by
Borrower, directly or indirectly through Wholly Owned Subsidiaries. Each Loan
Party is the record and beneficial owner of, and has good and marketable title
to, the Equity Interests pledged by it under the Security Agreement, free of any
and all Liens, rights or claims of other persons, except the security interest
created by the Security Agreement, and there are no outstanding warrants,
options or other rights to purchase, or shareholder, voting trust or similar
agreements outstanding with respect to, or property that is convertible into, or
that requires the issuance or sale of, any such Equity Interests.

            (b) No consent of any person including any other general or limited
partner, any other member of a limited liability company, any other shareholder
or any other trust beneficiary is necessary or reasonably desirable (from the
perspective of a secured party) in connection with the creation, perfection or
first priority status of the security interest of the Collateral Agent in any
Equity Interests pledged to the Collateral Agent for the benefit of the Secured
Parties under the Security Agreement or the exercise by the Collateral Agent of
the voting or other rights provided for in the Security Agreement or the
exercise of remedies in respect thereof.

            (c) An accurate organization chart, showing the ownership structure
of Borrower and each Subsidiary on the Closing Date, and after giving effect to
the Transactions, is set forth on Schedule 3.07(c).

            SECTION 3.08 LITIGATION; COMPLIANCE WITH LAWS. (a) There are no
actions, suits or proceedings at law or in equity by or before any Governmental
Authority now pending or, to the knowledge of any Company, threatened against or
affecting any Company or any business, property or rights of any Company (i)
that involve any Loan Document or any of the Transactions or (ii) as to which
there is a reasonable possibility of an adverse determination and that, if
adversely determined, could reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect.

            (b) Except for matters covered by Section 3.18, no Company or any of
its property is in violation of, nor will the continued operation of its
property as currently conducted violate, any Requirements of Law (including any
zoning or building ordinance, code or approval or any building permits) or any
restrictions of record affecting any Company's Real Property, Mineral Interests
or Pipelines or is in default with respect to any judgment, writ, injunction,
decree, rule or order of any Governmental Authority, where such violation or
default, individually or in the aggregate, could reasonably be expected to
result in a Material Adverse Effect.

            SECTION 3.09 AGREEMENTS. (a) No Company is a party to any
agreement or instrument or subject to any corporate or other constitutional
restriction that has resulted or could reasonably be expected to result in a
Material Adverse Effect.

            (b) No Company is in default in any manner under any provision of
any indenture or other agreement or instrument evidencing Indebtedness, or any
other agreement or instrument to which it

                                      -64-
<PAGE>

is a party or by which it or any of its property is or may be bound, where such
default could reasonably be expected to result in a Material Adverse Effect, and
no condition exists which, with the giving of notice or the lapse of time or
both, would constitute such a default.

            (c) Schedule 3.09(c) accurately and completely lists all material
agreements (other than leases or easements relating to Mineral Interests or
Pipelines) to which any Company is a party which are in effect on the date
hereof in connection with the operation of the business conducted thereby and
Borrower has delivered to the Administrative Agent complete and correct copies
of all such material agreements, including any amendments, supplements or
modifications with respect thereto, and all such agreements are in full force
and effect.

            SECTION 3.10 FEDERAL RESERVE REGULATIONS. (a) No Company is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of buying or carrying Margin Stock.

            (b) No part of the proceeds of any Loan or any Letter of Credit will
be used, whether directly or indirectly, and whether immediately, incidentally
or ultimately, for any purpose that entails a violation of, or that is
inconsistent with, the provisions of the regulations of the Board, including
Regulation T, U or X. The pledge of the Securities Collateral pursuant to the
Security Agreement does not violate such regulations.

            SECTION 3.11 INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY
ACT. No Company is (a) an "investment company" as defined in, or subject to
regulation under, the Investment Company Act of 1940, as amended, (b)
"controlled" by an "investment company" subject to regulation under the
Investment Company Act of 1940, as amended, or (c) a "holding company," an
"affiliate" of a "holding company" or a "subsidiary company" of a "holding
company," as defined in, or subject to regulation under, the Public Utility
Holding Company Act of 1935, as amended.

            SECTION 3.12 USE OF PROCEEDS. Borrower will use (a) the proceeds of
the Term B Loans to effect the Refinancing, pay related fees, commissions and
expenses, and for working capital and general corporate purposes (including to
effect Permitted Acquisitions), (b) the Revolving Loans and Swingline Loans
after the Closing Date for working capital and general corporate purposes
(including to effect Permitted Acquisitions), it being understood that no
Revolving Loans shall be made on the Closing Date and (c) the LC Facility Letter
of Credit to provide credit support for certain Commodity Hedging Obligations.

            SECTION 3.13 TAXES. Each Company has (a) timely filed or caused to
be timely filed all federal Tax Returns and all material state, local and
foreign Tax Returns or materials required to have been filed by it and all such
Tax Returns are true and correct in all material respects, (b) duly and timely
paid or caused to be duly and timely paid all Taxes (whether or not shown on any
Tax Return) due and payable by it and all assessments received by it, except
Taxes (i) that are being contested in good faith by appropriate proceedings and
for which such Company has set aside on its books adequate reserves in
accordance with GAAP and (ii) which could not, individually or in the aggregate,
have a Material Adverse Effect. Each Company has made adequate provision in
accordance with GAAP for all Taxes not yet due and payable. Each Company is
unaware of any proposed or pending tax assessments, deficiencies or audits that
could be reasonably expected to, individually or in the aggregate, result in a
Material Adverse Effect. No Company has ever been a party to any understanding
or arrangement constituting a "tax shelter" within the meaning of Section
6111(c), Section 6111(d) or Section 6662(d)(2)(C)(iii) of the Internal Revenue
Code, or has ever "participated" in a "reportable transaction" within the
meaning of Treasury Regulation Section 1.6011-4, except as could not be
reasonably expected to, individually or in the aggregate, result in a Material
Adverse Effect.

            SECTION 3.14 NO MATERIAL MISSTATEMENTS. No information, report,
financial statement, certificate, Borrowing Request, LC Request, exhibit or
schedule furnished by or on behalf of any Company to the Administrative Agent or
any Lender in connection with the negotiation of any Loan Document or included
therein or delivered pursuant thereto, taken as a whole, contained or contains
any material misstatement of fact or omitted or omits to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were or are made, not misleading as of the date such
information is dated or certified; provided that to the extent any such
information, report, financial statement, exhibit or schedule was based upon or
constitutes a forecast or projection, each Company represents only that it acted
in good faith and utilized reasonable assumptions and due care in the
preparation of such information, report, financial statement, exhibit or
schedule.

            SECTION 3.15 LABOR MATTERS. As of the date hereof and the Closing
Date, there are no strikes, lockouts or slowdowns against any Company pending
or, to the knowledge of any Company, threatened. The hours worked by and
payments made to employees of any Company have not been in violation of the Fair
Labor Standards Act of 1938, as amended, or any other applicable federal, state,
local or foreign law dealing with such matters in any manner which could
reasonably be expected to result in a Material Adverse Effect. All payments due
from any Company, or for which any claim may be made against any Company, on
account of wages and employee health and welfare insurance and other benefits,
have been paid or accrued as a liability on the books of such Company except
where the failure to do so could not reasonably be expected to result in a
Material Adverse Effect. The consummation of the Transactions will not give rise
to any right of termination or right of renegotiation on the part of any union
under any collective bargaining agreement to which any Company is bound.

            SECTION 3.16 SOLVENCY. Immediately after the consummation of the
Transactions to occur on the Closing Date and immediately following the making
of each Loan and after giving effect to the application of the proceeds of each
Loan, (a) the fair value of the properties of each Loan Party (individually and
on a consolidated basis with its Subsidiaries) will exceed its debts and
liabilities, subordinated, contingent or otherwise; (b) the present fair
saleable value of the property of each Loan Party (individually and on a
consolidated basis with its Subsidiaries) will be greater than the amount that
will be required to pay the probable liability of its debts and other
liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured; and (c) each Loan Party (individually
and on a consolidated basis with its Subsidiaries) will not have unreasonably
small capital with which to conduct its business in which it is engaged as such
business is now conducted and is proposed to be conducted following the Closing
Date.

            SECTION 3.17 EMPLOYEE BENEFIT PLANS. Each Company and its ERISA
Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events,
could reasonably be expected to result in material liability of any Company or
any of its ERISA Affiliates or the imposition of a Lien on any of the property
of any Company. The present value of all accumulated benefit obligations of all
underfunded Plans (based on the assumptions used for purposes of Statement of
Financial Accounting Standards No. 87) did not, as of the date of the most
recent financial statements reflecting such amounts, exceed by more than
$250,000 the fair market value of the property of all such underfunded Plans.
Using actuarial assumptions and computation methods consistent with subpart I of
subtitle E of Title IV of ERISA, the aggregate liabilities of each Company or
its ERISA Affiliates to all Multiemployer Plans in the event of a complete
withdrawal therefrom, as of the close of the most recent fiscal year of each
such Multiemployer Plan, could not reasonably be expected to result in a
Material Adverse Effect.

      Companies relating to compliance with or liability under Environmental Law

      any expense under Environmental Law pursuant to any order, decree,
      judgment or agreement by which it is bound or has assumed by contract or
      agreement, and no Company is conducting or financing any Response pursuant
      to any Environmental Law with respect to any Real Property, Mineral
      Interests or Pipelines or any other location;

            (ii) No Real Property or facility owned, operated or leased by the
      Companies and, to the knowledge of the Companies, no Real Property or

<PAGE>

            (iv) The execution, delivery and performance of this Agreement and
      the consummation of the transactions contemplated hereby will not require
      any notification, registration, filing, reporting, disclosure,
      investigation, remediation or cleanup pursuant to any Governmental Real
      Property Disclosure Requirements or any other Environmental Law; and

            (v) The Companies have made available to the Lenders all material
      records and files in the possession, custody or control of, or otherwise
      reasonably available to, the Companies concerning compliance with or
      liability under Environmental Law, including those concerning the
      existence of Hazardous Material at Real Property, Mineral Interests or
      Pipelines or facilities currently or formerly owned, operated, leased or
      used by the Companies.

            SECTION 3.19 INSURANCE. Schedule 3.19 sets forth a true, complete
and correct description of all insurance maintained by each Company as of the
Closing Date. All insurance maintained by the Companies is in full force and
effect, all premiums have been duly paid when due, no Company has received
notice of violation or cancellation thereof, the Premises, and the use,
occupancy and operation thereof, comply in all material respects with all
Insurance Requirements, and there exists no default under any Insurance
Requirement that would result in a reduction, limitation or cancellation of such

and liabilities as are customary for companies of a similar size engaged in
similar businesses in similar locations.

            SECTION 3.20 SECURITY DOCUMENTS. (a) The Security Agreement is

relevant jurisdiction by the filing of a statement or the taking of possession
or control, as applicable), in each case subject to no Liens other than
Permitted Collateral Liens.

            (b) When the Security Agreement or a short form thereof is filed in
the United States Patent and Trademark Office and the United States Copyright
Office, the Liens created by such Security Agreement shall constitute fully
perfected Liens on, and security interests in, all right, title and interest of

            SECTION 3.22 MINERAL INTERESTS. Borrower has good and defensible
title to all Mineral Interests described in the Reserve Report, free and clear
of all Liens except Permitted Liens and Immaterial Title Deficiencies. With the
exception of Immaterial Title Deficiencies, all such Mineral Interests are
valid, subsisting, and in full force and effect, and all rentals, royalties, and
other amounts due and payable in respect thereof have been duly paid. Without
regard to any consent or non-consent provisions of any joint operating agreement
covering any of Borrower's Proved Mineral Interests, and with the exception of
Immaterial Title Deficiencies, Borrower's share of (a) the costs for each Proved
Mineral In-

                                      -69-
<PAGE>

terest described in the Reserve Report is not greater than the decimal fraction
set forth in the Reserve Report, before and after payout, as the case may be,
and described therein by the respective designations "working interests," "WI,"
"gross working interest," "GWI," or similar terms, and (b) production from,
allocated to, or attributed to each such Proved Mineral Interest is not less
than the decimal fraction set forth in the Reserve Report, before and after
payout, as the case may be, and described therein by the designations "net
revenue interest," "NRI," or similar terms. Each well drilled in respect of each
Proved Producing Mineral Interest described in the Reserve Report (y) is capable
of, and is presently, either producing Hydrocarbons in commercially profitable
quantities or in the process of being worked over or enhanced, and Borrower is
currently receiving payments for its share of any such production, with no funds
in respect of any thereof being presently held in suspense, other than any such
funds being held in suspense pending delivery of appropriate division orders,
and (z) has been drilled, bottomed, completed, and operated in compliance with
all applicable Laws, in each case except where such failure would not have a
Material Adverse Effect, and no such well which is currently producing
Hydrocarbons is subject to any penalty in production by reason of such well
having produced in excess of its allowable production.

            SECTION 3.23 GAS BALANCING AGREEMENTS AND ADVANCE PAYMENT CONTRACTS.
On the Closing Date, (a) there is no Material Gas Imbalance, and (b) the
aggregate amount of all Advance Payments received by any Loan Party under
Advance Payment Contracts which have not been satisfied by delivery of
production does not exceed $500,000.

                                   ARTICLE IV

                         CONDITIONS TO CREDIT EXTENSIONS

            SECTION 4.01 CONDITIONS TO INITIAL CREDIT EXTENSION. The obligation
of each Lender and, if applicable, each Issuing Bank and the LC Facility Issuing
Bank, as the case may be, to fund the initial Credit Extension requested to be
made by it shall be subject to the prior or concurrent satisfaction of each of

required under this Section 5.04 or (ii) cause the Insurance Policy containing
any such Insurance Requirement to be replaced by a new policy complying with the
provisions of this Section 5.04.

            SECTION 5.05 TAXES. (a) Pay and discharge promptly when due all

successor provision) of the Code, which investment would or could reasonably be
expected to trigger a material increase in the net income of a United States

Collateral Agent otherwise consents, each leased Real Property of such Loan
Party which lease individually has a fair market value of at least $500,000, in
each case, as additional security for the Obligations (unless the subject
property is already mortgaged to a third party to the extent permitted by

additional security for the Obligations (unless the subject property is already
mortgaged to a third party to the extent permitted by Section 6.02); provided
that in the event that the aggregate value of all such Mineral Interests not
subject to a Mortgage exceeds $1.0 million, then the Company shall promptly
grant to the Collateral Agent, within 60 days after exceeding such threshold, a
security interest in and Mortgage on such Mineral Interests. Such Mortgages
shall be granted pursuant to documentation reasonably satisfactory in form and
substance to the Administrative Agent and the Collateral Agent and shall
constitute valid and enforceable perfected Liens subject only to Permitted
Collateral Liens or other Liens acceptable to the Collateral Agent. The
Mortgages or instruments related thereto shall be duly recorded or filed in such
manner and in such places as are required by law to establish, perfect, preserve
and protect the Liens in favor of the Collateral Agent required to be granted
pursuant to the Mortgages and all taxes, fees and other charges payable in
connection therewith shall be paid in full. Such Loan Party shall otherwise take
such actions and execute and/or deliver to the Collateral Agent such documents
as the Administrative Agent or the Collateral Agent shall require to confirm the
validity, perfection and priority of the Lien of any existing Mortgage or new
Mortgage against such after-acquired Mineral Interests (including and without

the Administrative Agent, the Collateral Agent or such Lender may require. If
the Administrative Agent, the Collateral Agent or the Required Lenders determine

                                    GUARANTEE

            SECTION 7.01 THE GUARANTEE. The Guarantors hereby, jointly and
severally guarantee, as a primary obligor and not as a surety to each Secured
Party and their respective successors and assigns, the prompt payment in full
when due (whether at stated maturity, by required prepayment, declaration,
demand, by acceleration or otherwise) of the principal of and interest
(including any interest, fees, costs or charges that would accrue but for the
provisions of the Title 11 of the United States Code after any bankruptcy or
insolvency petition under Title 11 of the United States Code) on the Loans made
by the Lenders to, and the Notes held by each Lender of, Borrower, and all other
Obligations from time to time owing to the Secured Parties by any Loan Party
under any Loan Document in each case strictly in accordance with the terms
thereof (such obligations being herein collectively called the "GUARANTEED
OBLIGATIONS"). The Guarantors hereby jointly and severally agree that if
Borrower or other Guarantor(s) shall fail to pay in full when due (whether at
stated maturity, by acceleration or otherwise) any of the Guaranteed
Obligations, the Guarantors will promptly pay the same in cash, without any
demand or notice whatsoever, and that in the case of any extension of time of
payment or renewal of any of the Guaranteed Obligations, the same will be
promptly paid in full when due (whether at extended maturity, by acceleration or
otherwise) in accordance with the terms of such extension or renewal.

            SECTION 7.02 OBLIGATIONS UNCONDITIONAL. The obligations of the
Guarantors under Section 7.01 shall constitute a guaranty of payment and to the
fullest extent permitted by applicable law, are absolute, irrevocable and
unconditional, joint and several, irrespective of the value, genuineness,
validity, regularity or enforceability of the Guaranteed Obligations of Borrower
under this Agreement, the Notes, if any, or any other agreement or instrument
referred to herein or therein, or any substitution, release or exchange of any
other guarantee of or security for any of the Guaranteed Obligations, and,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or Guarantor
(except for payment in full). Without limiting the generality of the foregoing,
it is agreed that the occurrence of any one or more of the following shall not
alter or impair the liability of the Guarantors hereunder which shall remain
absolute, irrevocable and unconditional under any and all circumstances as
described above:

            (i) at any time or from time to time, without notice to the
      Guarantors, the time for any performance of or compliance with any of the
      Guaranteed Obligations shall be extended, or such performance or
      compliance shall be waived;

            (ii) any of the acts mentioned in any of the provisions of this
      Agreement or the Notes, if any, or any other agreement or instrument
      referred to herein or therein shall be done or omitted;

            (iii) the maturity of any of the Guaranteed Obligations shall be
      accelerated, or any of the Guaranteed Obligations shall be amended in any
      respect, or any right under the Loan Documents or any other agreement or
      instrument referred to herein or therein shall be amended or

                                      -96-
<PAGE>

      waived in any respect or any other guarantee of any of the Guaranteed
      Obligations or any security therefor shall be released or exchanged in
      whole or in part or otherwise dealt with;

            (iv) any Lien or security interest granted to, or in favor of,
      Issuing Bank or any Lender or Agent as security for any of the Guaranteed
      Obligations shall fail to be perfected; or

            (v) the release of any other Guarantor pursuant to Section 7.09.

            The Guarantors hereby expressly waive diligence, presentment, demand
of payment, protest and all notices whatsoever, and any requirement that any
Secured Party exhaust any right, power or remedy or proceed against Borrower
under this Agreement or the Notes, if any, or any other agreement or instrument
referred to herein or therein, or against any other person under any other
guarantee of, or security for, any of the Guaranteed Obligations. The Guarantors
waive any and all notice of the creation, renewal, extension, waiver,
termination or accrual of any of the Guaranteed Obligations and notice of or
proof of reliance by any Secured Party upon this Guarantee or acceptance of this
Guarantee, and the Guaranteed Obligations, and any of them, shall conclusively
be deemed to have been created, contracted or incurred in reliance upon this
Guarantee, and all dealings between Borrower and the Secured Parties shall
likewise be conclusively presumed to have been had or consummated in reliance
upon this Guarantee. This Guarantee shall be construed as a continuing,
absolute, irrevocable and unconditional guarantee of payment without regard to
any right of offset with respect to the Guaranteed Obligations at any time or
from time to time held by Secured Parties, and the obligations and liabilities
of the Guarantors hereunder shall not be conditioned or contingent upon the
pursuit by the Secured Parties or any other person at any time of any right or
remedy against Borrower or against any other person which may be or become
liable in respect of all or any part of the Guaranteed Obligations or against
any collateral security or guarantee therefor or right of offset with respect
thereto. This Guarantee shall remain in full force and effect and be binding in
accordance with and to the extent of its terms upon the Guarantors and the
successors and assigns thereof, and shall inure to the benefit of the Lenders,
and their respective successors and assigns, notwithstanding that from time to
time during the term of this Agreement there may be no Guaranteed Obligations
outstanding.

            SECTION 7.03 REINSTATEMENT. The obligations of the Guarantors under
this Article VII shall be automatically reinstated if and to the extent that for
any reason any payment by or on behalf of Borrower or other Loan Party in
respect of the Guaranteed Obligations is rescinded or must be otherwise restored
by any holder of any of the Guaranteed Obligations, whether as a result of any
proceedings in bankruptcy or reorganization or otherwise.

            SECTION 7.04 SUBROGATION; SUBORDINATION. Each Guarantor hereby
agrees that until the indefeasible payment and satisfaction in full in cash of
all Guaranteed Obligations and the expiration and termination of the Commitments
of the Lenders under this Agreement it shall waive any claim and shall not
exercise any right or remedy, direct or indirect, arising by reason of any
performance by it of its guarantee in Section 7.01, whether by subrogation or
otherwise, against Borrower or any other Guarantor of any of the Guaranteed
Obligations or any security for any of the Guaranteed Obligations. Any
Indebtedness of any Loan Party permitted pursuant to Section 6.01(d) shall be
subordinated to such Loan Party's Obligations in the manner set forth in the
Intercompany Note evidencing such Indebtedness.

            SECTION 7.05 REMEDIES. The Guarantors jointly and severally agree
that, as between the Guarantors and the Lenders, the obligations of Borrower
under this Agreement and the Notes, if any, may be declared to be forthwith due
and payable as provided in Article VIII (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Article
VIII) for purposes of Section 7.01, notwithstanding any stay, injunction or
other prohibition preventing such declaration (or such obligations from becoming
automatically due and payable) as against Borrower and that, in

                                      -97-
<PAGE>

the event of such declaration (or such obligations being deemed to have become
automatically due and payable), such obligations (whether or not due and payable
by Borrower) shall forthwith become due and payable by the Guarantors for
purposes of Section 7.01.

            SECTION 7.06 INSTRUMENT FOR THE PAYMENT OF MONEY. Each Guarantor
hereby acknowledges that the guarantee in this Article VII constitutes an
instrument for the payment of money, and consents and agrees that any Lender or
Agent, at its sole option, in the event of a dispute by such Guarantor in the
payment of any moneys due hereunder, shall have the right to bring a
motion-action under New York CPLR Section 3213.

            SECTION 7.07 CONTINUING GUARANTEE. The guarantee in this Article VII
is a continuing guarantee of payment, and shall apply to all Guaranteed
Obligations whenever arising.

            SECTION 7.08 GENERAL LIMITATION ON GUARANTEE OBLIGATIONS. In any
action or proceeding involving any state corporate limited partnership or
limited liability company law, or any applicable state, federal or foreign
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Guarantor under Section 7.01
would otherwise be held or determined to be void, voidable, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account
of the amount of its liability under Section 7.01, then, notwithstanding any
other provision to the contrary, the amount of such liability shall, without any
further action by such Guarantor, any Loan Party or any other person, be
automatically limited and reduced to the highest amount that is valid and
enforceable and not subordinated to the claims of other creditors as determined
in such action or proceeding.

            SECTION 7.09 RELEASE OF GUARANTORS. If, in compliance with the terms
and provisions of the Loan Documents, all or substantially all of the Equity
Interests or property of any Guarantor are sold or otherwise transferred (a
"TRANSFERRED GUARANTOR") to a person or persons, none of which is Borrower or a
Subsidiary, such Transferred Guarantor shall, upon the consummation of such sale
or transfer, be released from its obligations under this Agreement (including
under Section 11.03 hereof) and its obligations to pledge and grant any
Collateral owned by it pursuant to any Security Document and, in the case of a
sale of all or substantially all of the Equity Interests of the Transferred
Guarantor, the pledge of such Equity Interests to the Collateral Agent pursuant
to the Security Agreements shall be released, and the Collateral Agent shall
take such actions as are necessary to effect each release described in this
Section 7.09 in accordance with the relevant provisions of the Security
Documents.

                                  ARTICLE VIII

      mandatory) thereof or by acceleration thereof or otherwise;

            (b) default shall be made in the payment of any interest on any Loan

      connection with any Loan Document or the borrowings or issuances of
      Letters of Credit hereunder, or any representation, warranty, statement or
      information contained in any report, certificate, financial statement or
      other instrument furnished in connection with or pursuant to any Loan
      Document, shall prove to have been false or misleading in any material
      respect when so made, deemed made or furnished;

            (d) default shall be made in the due observance or performance by
      any Company of any covenant, condition or agreement contained in Sections

      term, covenant, condition or agreement contained in any agreement or

      holder or holders of such Indebtedness or a trustee or other
      representative on its or their behalf (with or without the giving of

                                   ARTICLE IX

             COLLATERAL ACCOUNT; APPLICATION OF COLLATERAL PROCEEDS

            SECTION 9.01 COLLATERAL ACCOUNT. (a) The Collateral Agent is hereby
authorized to establish and maintain at its office at 677 Washington Boulevard,
Stamford, Connecticut 06901, in the name of the Collateral Agent, a restricted
deposit account designated "Quest Cherokee Collateral Account." Each Loan Party
shall deposit into the Collateral Account from time to time (i) the cash
proceeds of any of the Collateral (including pursuant to any disposition
thereof) to the extent contemplated herein or in any other Loan Document, (ii)
the cash proceeds of any Casualty Event with respect to Collateral, to the
extent contemplated herein or in any other Loan Document, and (iii) any cash
such Loan Party is required to pledge as additional collateral security
hereunder pursuant to the Loan Documents.

            (b) The balance from time to time in the Collateral Account shall
constitute part of the Collateral and shall not constitute payment of the
Obligations until applied as hereinafter provided. So long as no Event of
Default has occurred and is continuing or will result therefrom, the Collateral
Agent shall within two Business Days of receiving a request of the applicable
Loan Party for release of cash proceeds (i) from the Collateral Account
constituting Net Cash Proceeds relating to any Casualty Event or Asset Sale
remit such cash proceeds on deposit in the Collateral Account to or upon the
order of such Loan Party, so long as such Loan Party has satisfied the
conditions relating thereto set forth in Section 9.02 and (ii) with respect to
the LC Sub-Account, remit such Net Cash Proceeds on deposit in the LC
Sub-Account to or upon the order of such Loan Party (x) at such time as all
Letters of Credit shall have been terminated and all of the liabilities in
respect of the Letters of Credit have been paid in full or (y) otherwise in
accordance with Section 2.18(i). At any time following the occurrence and during
the continuance of an Event of Default, the Collateral Agent may (and, if
instructed by the Required Lenders as specified herein, shall) in its (or their)
discretion apply or cause to be applied (subject to collection) the balance from
time to time outstanding to the credit of the Collateral Account to the payment
of the Obligations in the manner specified in Section 9.03 hereof subject,
however, in the case of amounts deposited in the LC Sub-Account, to the
provisions of Sections 2.18(i) and 9.03. The Loan Parties shall have no right to
withdraw, transfer or otherwise receive any funds deposited in the Collateral
Account except to the extent specifically provided herein.

            (c) Amounts on deposit in the Collateral Account shall be invested
and reinvested from time to time in Cash Equivalents as the applicable Loan
Party (or, after the occurrence and during the continuance of an Event of
Default, the Collateral Agent) shall determine by written instruction to the
Collateral Agent, or if no such instructions are given, then as the Collateral
Agent, in its sole discretion, shall determine which Cash Equivalents shall be
held in the name and be under the control of the Collateral Agent (or any
sub-agent); provided that at any time after the occurrence and during the
continuance of an Event of Default, the Collateral Agent may (and, if instructed
by the Required Lenders as specified herein, shall) in its (or their) discretion
at any time and from time to time elect to liquidate any such Cash Equivalents
and to apply or cause to be applied the proceeds thereof to the payment of the
Obligations in the manner specified in Section 9.03 hereof subject, however, in
the case of amounts deposited in the LC Sub-Account, to the provisions of
Section 2.18(i).

                                     -101-
<PAGE>

            (d) Amounts deposited into the Collateral Account as cover for
liabilities in respect of Letters of Credit under any provision of this
Agreement requiring such cover shall be held by the Administrative Agent in a
separate sub-account designated as the "LC Sub-Account" (the "LC SUB-ACCOUNT")
and, subject to Section 2.18(i), all amounts held in the LC Sub-Account shall
constitute collateral security to be applied in accordance with Section 2.18(i).

            SECTION 9.02 PROCEEDS OF DESTRUCTION, TAKING AND COLLATERAL
DISPOSITIONS. So long as no Event of Default shall have occurred and be
continuing, in the event the applicable Loan Party elects to reinvest Net Cash
Proceeds in respect of any Asset Sale or Casualty Event in accordance with the
provisions of Sections 2.10(c) and 2.10(f) as applicable, the Collateral Agent
shall receive at least 10 days' prior notice of each request for payment and
shall not release any part of such Net Cash Proceeds, until the applicable Loan
Party has furnished to the Collateral Agent (i) an Officers' Certificate setting
forth: (A) a brief description of the reinvestment to be made, (B) the dollar
amount of the expenditures to be made, or costs incurred by such Loan Party in
connection with such reinvestment and (C) evidence that the properties acquired
in connection with such reinvestment have a fair market value at least equal to
the amount of such Net Cash Proceeds requested to be released from the
Collateral Account and (ii) all security agreements and Mortgages and other
items required by the provisions of Sections 5.11 and 5.12 to, among other
things, subject such reinvestment properties to the Lien of the Security
Documents in favor of the Collateral Agent, for its benefit and for the benefit
of the other Secured Parties.

            SECTION 9.03 APPLICATION OF PROCEEDS. The proceeds received by the
Collateral Agent in respect of any sale of, collection from or other realization
upon all or any part of the Collateral pursuant to the exercise by the
Collateral Agent of its remedies shall be applied, in full or in part, together
with any other sums then held by the Collateral Agent pursuant to this
Agreement, promptly by the Collateral Agent as follows:

            (a) First, to the payment of all reasonable costs and expenses,
      fees, commissions and taxes of such sale, collection or other realization
      including compensation to the Collateral Agent and its agents and counsel,
      and all expenses, liabilities and advances made or incurred by the
      Collateral Agent in connection therewith and all amounts for which the
      Collateral Agent is entitled to indemnification pursuant to the provisions
      of any Loan Document, together with interest on each such amount at the
      highest rate then in effect under this Agreement from and after the date
      such amount is due, owing or unpaid until paid in full;

            (b) Second, to the payment of all other reasonable costs and
      expenses of such sale, collection or other realization including
      compensation to the other Secured Parties and their agents and counsel and
      all costs, liabilities and advances made or incurred by the other Secured
      Parties in connection therewith, together with interest on each such
      amount at the highest rate then in effect under this Agreement from and
      after the date such amount is due, owing or unpaid until paid in full;

            (c) Third, without duplication of amounts applied pursuant to
      clauses (a) and (b) above, to the indefeasible payment in full in cash,
      pro rata, of interest and other amounts constituting Obligations (other
      than principal and Reimbursement Obligations) in each case equally and
      ratably in accordance with the respective amounts thereof then due and
      owing;

            (d) Fourth, to the indefeasible payment in full in cash, pro rata,
      of principal amount of the Obligations (including Reimbursement
      Obligations); and

                                     -102-
<PAGE>

            (e) Fifth, the balance, if any, to the person lawfully entitled
      thereto (including the applicable Loan Party or its successors or assigns)
      or as a court of competent jurisdiction may direct.

            In the event that any such proceeds are insufficient to pay in full
the items described in clauses (a) through (e) of this Section 9.03, the Loan
Parties shall remain liable, jointly and severally, for any deficiency.

                                   ARTICLE X

                THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT

            SECTION 10.01 APPOINTMENT. Each Lender hereby irrevocably designates
and appoints each of the Administrative Agent and the Collateral Agent as an
agent of such Lender under this Agreement and the other Loan Documents. Each
Lender irrevocably authorizes each Agent, in such capacity, through its agents
or employees, to take such actions on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to such Agent by the terms of this
Agreement and the other Loan Documents, together with such actions and powers as
are reasonably incidental thereto.

            SECTION 10.02 AGENT IN ITS INDIVIDUAL CAPACITY. Each person serving
as an Agent hereunder shall have the same rights and powers in its capacity as a
Lender as any other Lender and may exercise the same as though it were not an
Agent, and such person and its Affiliates may accept deposits from, lend money
to and generally engage in any kind of business with Borrower or any Subsidiary
or other Affiliate thereof as if it were not an Agent hereunder.

            SECTION 10.03 EXCULPATORY PROVISIONS. No Agent shall have any duties
or obligations except those expressly set forth in the Loan Documents. Without
limiting the generality of the foregoing, (a) no Agent shall be subject to any
fiduciary or other implied duties, regardless of whether a Default has occurred
and is continuing, (b) no Agent shall have any duty to take any discretionary
action or exercise any discretionary powers, except discretionary rights and
powers expressly contemplated by the Loan Documents that such Agent is required
to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 11.02), and (c) except as expressly set forth in the Loan
Documents, no Agent shall have any duty to disclose or shall be liable for the
failure to disclose, any information relating to Borrower or any of its
Subsidiaries that is communicated to or obtained by the bank serving as such
Agent or any of its Affiliates in any capacity. No Agent shall be liable for any
action taken or not taken by it with the consent or at the request of the
Required Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 11.02) or in the
absence of its own gross negligence or willful misconduct. No Agent shall be
deemed to have knowledge of any Default unless and until written notice thereof
is given to such Agent by Borrower or a Lender, and no Agent shall be
responsible for or have any duty to ascertain or inquire into (i) any statement,
warranty or representation made in or in connection with any Loan Document, (ii)
the contents of any certificate, report or other document delivered thereunder
or in connection therewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth in any Loan
Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Loan Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article IV or elsewhere in any Loan
Document.

            SECTION 10.04 RELIANCE BY AGENT. Each Agent shall be entitled to
rely upon, and shall not incur any liability for relying upon, any notice,
request, certificate, consent, statement, instrument, document or other writing
believed by it to be genuine and to have been signed or sent by a proper

                                     -103-
<PAGE>

person. Each Agent also may rely upon any statement made to it orally and
believed by it to be made by a proper person, and shall not incur any liability
for relying thereon. Each Agent may consult with legal counsel (who may be
counsel for Borrower), independent accountants and other advisors selected by
it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or advisors.

            SECTION 10.05 DELEGATION OF DUTIES. Each Agent may perform any and
all its duties and exercise its rights and powers by or through any one or more
sub-agents appointed by such Agent. Each Agent and any such sub-agent may
perform any and all its duties and exercise its rights and powers through their
respective Affiliates. The exculpatory provisions of the preceding paragraphs
shall apply to any such sub-agent and to the Affiliates of each Agent and any
such sub-agent, and shall apply to their respective activities in connection
with the syndication of the credit facilities provided for herein as well as
activities as Agent.

            SECTION 10.06 SUCCESSOR AGENT. Each Agent may resign as such at any
time upon at least 30 days' prior notice to the Lenders, the Issuing Bank, the
LC Facility Issuing Bank and Borrower. Upon any such resignation, the Required
Lenders shall have the right, in consultation with Borrower, to appoint a
successor Agent from among the Lenders. If no successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Agent gives notice of its resignation, then
the retiring Agent may, on behalf of the Lenders, the Issuing Bank and the LC
Facility Issuing Bank appoint a successor Agent, which successor shall be a
commercial banking institution organized under the laws of the United States (or
any State thereof) or a United States branch or agency of a commercial banking
institution, in each case, having combined capital and surplus of at least
$250.0 million; provided that if such retiring Agent is unable to find a
commercial banking institution which is willing to accept such appointment and
which meets the qualifications set forth above, the retiring Agent's resignation
shall nevertheless thereupon become effective, and the Lenders shall assume and
perform all of the duties of the Agent hereunder until such time, if any, as the
Required Lenders appoint a successor Agent.

            Upon the acceptance of its appointment as an Agent hereunder by a
successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. The fees
payable by Borrower to a successor Agent shall be the same as those payable to
its predecessor unless otherwise agreed between Borrower and such successor.
After an Agent's resignation hereunder, the provisions of this Article X and
Section 11.03 shall continue in effect for the benefit of such retiring Agent,
its sub-agents and their respective Affiliates in respect of any actions taken
or omitted to be taken by any of them while it was acting as Agent.

            SECTION 10.07 NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender
acknowledges that it has, independently and without reliance upon any Agent or
any other Lender and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance upon any Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Loan Document or related agreement or any document furnished hereunder
or thereunder.

            SECTION 10.08 NAME AGENTS. The parties hereto acknowledge that the
Documentation Agent and the Syndication Agent hold such titles in name only, and
that such titles confer no additional rights or obligations relative to those
conferred on any Lender hereunder.

                                     -104-
<PAGE>

            SECTION 10.09 INDEMNIFICATION. The Lenders severally agree to
indemnify each Agent in its capacity as such (to the extent not reimbursed by
Borrower or the Guarantors and without limiting the obligation of Borrower or
the Guarantors to do so), ratably according to their respective outstanding
Loans and Commitments in effect on the date on which indemnification is sought
under this Section 10.09 (or, if indemnification is sought after the date upon
which all Commitments shall have terminated and the Loans and Reimbursement
Obligations shall have been paid in full, ratably in accordance with such
outstanding Loans and Commitments as in effect immediately prior to such date),
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever that may at any time (whether before or after the payment of the
Loans and Reimbursement Obligations) be imposed on, incurred by or asserted
against such Agent in any way relating to or arising out of, the Commitments,
this Agreement, any of the other Loan Documents or any documents contemplated by
or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by such Agent under or in connection with
any of the foregoing; provided that no Lender shall be liable for the payment of
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements that are found by a
final and nonappealable decision of a court of competent jurisdiction to have
resulted from such Agent's gross negligence or willful misconduct. The
agreements in this Section shall survive the payment of the Loans and all other
amounts payable hereunder.

                Telecopy No.: (203) 719-4176.

All notices and other communications given to any party hereto in accordance
with the provisions of this Agreement shall be deemed to have been given on the
date of receipt if delivered by hand or overnight courier service or sent by
telecopy or by certified or registered mail, in each case delivered, sent or
mailed (properly addressed) to such party as provided in this Section 11.01 or

accordance with this Section 11.01, and failure to deliver courtesy copies of
notices and other communications shall in no event affect the validity or
effectiveness of such notices and other communications.

            SECTION 11.02 WAIVERS; AMENDMENT. (a) No failure or delay by any
Agent, the Issuing Bank, the LC Facility Issuing Bank or any Lender in
exercising any right or power hereunder or under any other Loan Document 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 each Agent, the
Issuing Bank, the LC Facility Issuing Bank and the Lenders hereunder and under
the other Loan Documents are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of any Loan
Document or consent to any departure by any Loan Party therefrom shall in any
event be effective unless the same shall be permitted by paragraph (b) of this
Section, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of
the foregoing, the making of a Loan, the funding of an LC Facility Deposit or
issuance of a Letter of Credit shall not be construed as a waiver of any
Default, regardless of whether any Agent, any Lender, the Issuing Bank or the LC
Facility Issuing Bank may have had notice or knowledge of such Default at the
time.

            (b) Except as provided in paragraphs (c) and (d) below, neither this
Agreement nor any other Loan Document nor any provision hereof or thereof may be
waived, amended, supplemented or modified except, in the case of this Agreement,
pursuant to an agreement or agreements in writing entered into by Borrower and
the Required Lenders or, in the case of any other Loan Document, pursuant to an
agreement or agreements in writing entered into by the Administrative Agent, the
Collateral Agent (in the case of any Security Document) and the Loan Party or
Loan Parties that are parties thereto, in each case with the written consent of
the Required Lenders; provided that no such agreement shall:

            (i) increase the Commitment of any Lender without the written
      consent of such Lender; reduce the principal amount or premium of any Loan
      or LC Disbursement or reduce the rate of interest thereon, or reduce any
      Fees payable hereunder, or change the currency of payment of any
      Obligation, without the written consent of each Lender affected thereby;

            (ii) postpone or extend the maturity of any Loan, or any scheduled
      date of payment of or the installment otherwise due on the principal
      amount of any Term B Loan under Section 2.09, or the required date of
      payment of any Reimbursement Obligation, or the date on which the LC
      Facility Deposits are required to be returned to the LC Facility Lenders
      or any date for the payment of any interest or fees payable hereunder, or
      reduce the amount of, waive or excuse any such payment, or postpone the
      scheduled date of expiration of any Commitment or postpone the scheduled
      date of expiration of any Letter of Credit beyond the Revolving Maturity
      Date or the

                                     -106-
<PAGE>

      LC Facility Maturity Date, as applicable, without the written consent of
      each Lender affected thereby;

            (iii) change Section 2.14(b) or (c) in a manner that would alter the
      pro rata sharing of payments or setoffs required thereby, without the
      written consent of each Lender;

            (iv) change the percentage set forth in the definition of "Required
      Lenders" or any other provision of any Loan Document (including this
      Section) specifying the number or percentage of Lenders (or Lenders of any
      Class) required to waive, amend or modify any rights thereunder or make
      any determination or grant any consent thereunder, without the written
      consent of each Lender (or each Lender of such Class, as the case may be);

            (v) release any Guarantor from its Guarantee (except as expressly
      provided in Article VII), or limit its liability in respect of such
      Guarantee, without the written consent of each Lender;

            (vi) release all or a substantial portion of the Collateral from the
      Liens of the Security Documents or alter the relative priorities of the
      Obligations entitled to the Liens of the Security Documents (except in
      connection with securing additional Obligations equally and ratably with
      the other Obligations), in each case without the written consent of each
      Lender;

            (vii) change any provisions of any Loan Document in a manner that by
      its terms adversely affects the rights in respect of payments due to
      Lenders holding Loans of any Class differently than those holding Loans of
      any other Class, without the written consent of Lenders holding a majority
      in interest of the outstanding Loans and unused Commitments of each
      affected Class; or

            (viii) without the consent of the Required Lenders and Term B
      Lenders holding more than 50% of the principal amount of the outstanding
      Term B Loans, change the order of application of prepayments among Term B
      Loans and Revolving Commitments under Section 2.10(h) or change the
      application of prepayments of Term B Loans set forth in Section 2.10(h) to
      the remaining scheduled amortization payments to be made thereon under
      Section 2.09;

provided, further, that (1) no such agreement shall amend, modify or otherwise
affect the rights or duties of the Administrative Agent, the Collateral Agent,
the Issuing Bank, the LC Facility Issuing Bank or the Swingline Lender without
the prior written consent of the Administrative Agent, the Issuing Bank, the LC
Facility Issuing Bank or the Swingline Lender, as the case may be, (2) any
waiver, amendment or modification of this Agreement that by its terms affects
the rights or duties under this Agreement of the Revolving Lenders (but not the
Term B Lenders) or the Term B Lenders (but not the Revolving Lenders) may be
effected by an agreement or agreements in writing entered into by Borrower and
requisite percentage in interest of the affected Class of Lenders that would be
required to consent thereto under this Section if such Class of Lenders were the
only Class of Lenders hereunder at the time and (3) any waiver, amendment or
modification prior to the achievement of a Successful Syndication may not be
effected without the written consent of the Arranger. Notwithstanding the
foregoing, any provision of this Agreement may be amended by an agreement in
writing entered into by Borrower, the Required Lenders and the Administrative
Agent (and, if their rights or obligations are affected thereby, the Issuing
Bank, the LC Facility Issuing Bank and the Swingline Lender) if (x) by the terms
of such agreement the Commitment of each Lender not consenting to the amendment
provided for therein shall terminate upon the effectiveness of such amendment
and (y) at the time such amendment becomes effective, each Lender not consenting
thereto receives payment in full of the principal of, premium, if any, and
interest accrued on each Loan made by it and all other amounts owing to it or
accrued for its account under this Agreement.

                                     -107-

            (c) If, in connection with any proposed change, waiver, discharge or
termination of the provisions of this Agreement as contemplated by Section
11.02(b) (other than clause (iii) of such Section), the consent of the
Supermajority Lenders is obtained but the consent of one or more of such other
Lenders whose consent is required is not obtained, then Borrower shall have the
right to replace all, but not less than all, of such non-consenting Lender or
Lenders (so long as all non-consenting Lenders are so replaced) with one or more
persons pursuant to Section 2.16 so long as at the time of such replacement each
such new Lender consents to the proposed change, waiver, discharge or
termination; provided, however, that Borrower shall not have the right to
replace a Lender solely as a result of the exercise of such Lender's rights (and
the withholding of any required consent by such Lender) pursuant to clause (iii)
of Section 11.02(b).

            SECTION 11.03 EXPENSES; INDEMNITY. (a) The Loan Parties agree,
jointly and severally, to pay, promptly upon demand:

            (i) all reasonable costs and expenses incurred by the Arranger, the
      Administrative Agent, the Collateral Agent, the Swingline Lender, the
      Issuing Bank and the LC Facility Issuing Bank, including the reasonable
      fees, charges and disbursements of Advisors for the Arranger, the
      Administrative Agent, the Collateral Agent, the Swingline Lender, the
      Issuing Bank and the LC Facility Issuing Bank in connection with the
      syndication of the Loans, the LC Facility Deposits and Commitments, the
      preparation, execution and delivery of the Loan Documents, the
      administration of the Loans, the LC Facility Deposits and Commitments, the
      perfection and maintenance of the Liens securing the Collateral and any
      actual or proposed amendment, supplement or waiver of any of the Loan
      Documents (whether or not the transactions contemplated hereby or thereby
      shall be consummated);

            (ii) all costs and expenses incurred by the Administrative Agent or
      the Collateral Agent, including the reasonable fees, charges and
      disbursements of Advisors for the Administrative Agent and the Collateral
      Agent, in connection with any action, suit or other proceeding affecting
      the Collateral or any part thereof, in which action, suit or proceeding
      the Administrative Agent or the Collateral Agent is made a party or
      participates or in which the right to use the Collateral or any part
      thereof is threatened, or in which it becomes necessary in the judgment of
      the Administrative Agent or the Collateral Agent to defend or uphold the
      Liens granted by the Security Documents (including any action, suit or
      proceeding to establish or uphold the compliance of the Collateral with
      any Requirements of Law);

            (iii) all costs and expenses incurred by the Arranger, the
      Administrative Agent, the Collateral Agent, the Swingline Lender, the
      Issuing Bank, the LC Facility Issuing Bank or any Lender, including the
      reasonable fees, charges and disbursements of Advisors for the Arranger,
      the Administrative Agent, the Collateral Agent, the Swingline Lender, the
      Issuing Bank, the LC Facility Issuing Bank or any Lender, incurred in
      connection with the enforcement or protection of its rights under the Loan
      Documents, including its rights under this Section 11.03(a), or in
      connection with the Loans made, the LC Facility Deposit funded or Letters
      of Credit issued hereunder and the collection of the Obligations,
      including all such costs and expenses incurred during any workout,
      restructuring or negotiations in respect of the Obligations; and

            (iv) all documentary and similar taxes and charges in respect of the
      Loan Documents.

For purposes of this Section 11.03(a), "ADVISORS" shall mean legal counsel
(including local counsel), auditors, accountants, consultants, appraisers or
other advisors; provided that (x) in the case of clause (i), the engagement of
any Advisors other than legal counsel (including local counsel) shall be subject
to approval by Borrower (which approval shall not be unreasonably withheld) and
(y) in the case of clause

                                     -108-
<PAGE>

(iii), the engagement of any Advisors other than one firm of legal counsel by
any Lender shall be subject to approval by the Administrative Agent.

            (b) The Loan Parties agree, jointly and severally, to indemnify the
Agents, each Lender, the Issuing Bank, the LC Facility Issuing Bank and the
Swingline Lender, each Affiliate of any of the foregoing persons and each of
their respective partners, controlling persons, directors, officers, trustees,
employees and agents (each such person being called an "INDEMNITEE") against,
and to hold each Indemnitee harmless from, all reasonable out-of-pocket costs
and any and all losses, claims, damages, liabilities (including, but not limited
to, environmental liabilities), penalties, judgments, suits and related
expenses, including reasonable counsel fees, charges and disbursements, incurred
by or asserted against any Indemnitee arising out of, in any way connected with,
or as a result of (i) the execution, delivery, performance, administration or
enforcement of the Loan Documents, (ii) any actual or proposed use of the
proceeds of the Loans or issuance of Letters of Credit, (iii) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto, or (iv) any actual or alleged
presence or Release or threatened Release of Hazardous Materials, on, at, under
or from any property owned, leased or operated by any Company at any time, or
any Environmental Claim related in any way to any Company; 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 primarily from the gross negligence or willful misconduct of such
Indemnitee.

            (c) The provisions of this Section 11.03 shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of the Loans and Reimbursement Obligations, the release of all or any
portion of the Collateral, the expiration of the Commitments, the expiration of
any Letter of Credit, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document, or any investigation
made by or on behalf of the Agents, the Issuing Bank, the LC Facility Issuing
Bank or any Lender. All amounts due under this Section 11.03 shall be payable on
written demand therefor accompanied by reasonable documentation with respect to
any reimbursement, indemnification or other amount requested.

            (d) To the extent that Borrower fails to promptly pay any amount
required to be paid by it to the Agents, the Issuing Bank, the LC Facility
Issuing Bank or the Swingline Lender under paragraph (a) or (b) of this Section,
each Lender severally agrees to pay to the Agents, the Issuing Bank, the LC
Facility Issuing Bank or the Swingline Lender, as the case may be, such Lender's
pro rata share (determined as of the time that the applicable unreimbursed
expense or indemnity payment is sought) of such unpaid amount; provided that the
unreimbursed expense or indemnified loss, claim, damage, liability or related
expense, as the case may be, was incurred by or asserted against any of the
Agents, the Issuing Bank, the LC Facility Issuing Bank or the Swingline Lender
in its capacity as such. For purposes hereof, a Lender's "pro rata share" shall
be determined based upon its share of the sum of the total Revolving Exposure,
the LC Facility LC Exposure, outstanding Term B Loans and unused Commitments at
the time.

            SECTION 11.04 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 (including any
Affiliate of the Issuing Bank or LC Facility Issuing Bank, as applicable, that
issues any Letter of Credit), except that Borrower may not assign or otherwise
transfer any of its rights or obligations hereunder without the prior written
consent of the Administrative Agent, the Collateral Agent, the Issuing Bank, the
LC Facility Issuing Bank, the Swingline Lender and each Lender (and any
attempted assignment or transfer by Borrower without such consent shall be null
and void). Nothing in this Agreement, express or implied, shall be construed to
confer upon any person (other than the parties hereto, their respective
successors and assigns permitted hereby (including any Affiliate of the Issuing

                                     -109-
<PAGE>

Bank or LC Facility Issuing Bank, as applicable, that issues any Letter of
Credit) and, to the extent expressly contemplated hereby, the other Indemnitees)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

            (b) Any Lender shall have the right at any time to assign to an
Eligible Assignee all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment, LC Facility Deposit,
and the Loans at the time owing to it); provided that (i) except in the case of
an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, or an
assignment of the entire remaining amount of the assigning Lender's Commitment,
LC Facility Deposit, or Loans, the amount of the Commitment, LC Facility
Deposit, or Loans 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 $1.0
million unless each of Borrower and the Administrative Agent otherwise consents,
(ii) 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,
except that this clause (ii) shall not be construed to prohibit the assignment
of a proportionate part of all the assigning Lender's rights and obligations in
respect of one Class of Commitments, LC Facility Deposits or Loans, (iii) 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 (iv) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire. Subject to acceptance and
recording thereof pursuant to paragraph (d) 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 (provided that any liability of Borrower to such assignee
under Section 2.12, 2.13 or 2.15 shall be limited to the amount, if any, that
would have been payable thereunder by Borrower in the absence of such
assignment, except to the extent any such amounts are attributable to a Change
in Law occurring after the date of such assignment), 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 2.12,
2.13, 2.15 and 11.03 and subject to the obligations of Section 2.16).

            (c) The Administrative Agent, acting for this purpose as an agent of
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, LC Facility Deposits and LC Disbursements owing to, each Lender pursuant
to the terms hereof from time to time (the "REGISTER"). The entries in the
Register shall be conclusive in the absence of manifest error, and Borrower, the
Administrative Agent, the Issuing Bank, the LC Facility Issuing Bank 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 Borrower, the Issuing Bank, the LC Facility Issuing Bank, the
Collateral Agent, the Swingline Lender and any Lender (with respect to its own
interest only), at any reasonable time and from time to time upon reasonable
prior notice.

            (d) Upon its receipt of a duly completed Assignment and Assumption
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section and any written consent to such assignment required by paragraph
(b) 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.

            (e) Any Lender shall have the right at any time, without the consent
of Borrower, the Administrative Agent, the Issuing Bank, the LC Facility Issuing
Bank or the Swingline Lender, to sell participations to one or more banks or
other entities (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,
LC Facility Deposits and the Loans owing to it); provided that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) Borrower, the Administrative Agent, the Issuing Bank,
the LC Facility Issuing Bank and the other Lenders shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce the Loan Documents and to approve any amendment,
modification or waiver of any provision of the Loan Documents; 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 clause (i), (ii) or (iii) of the first proviso to Section 11.02(b)
that affects such Participant. Subject to paragraph (f) of this Section,
Borrower agrees that each Participant shall be entitled to the benefits of
Sections 2.12, 2.13 and 2.15 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section,
but only if such participant agrees to comply with Section 2.16 as if it was a
Lender. To the extent permitted by law, each Participant also shall be entitled
to the benefits of Section 11.08 as though it were a Lender; provided that such
Participant agrees in writing to be subject to Section 2.14(c) as though it were
a Lender. Each Lender shall, acting for this purpose as an agent of Borrower,
maintain at one of its offices a register for the recordation of the names and
addresses of its Participants, and the amount and terms of its participations;
provided that no Lender shall be required to disclose or share the information
contained in such register with Borrower or any other party, except as required
by applicable law.

            (f) A Participant shall not be entitled to receive any greater
payment under Section 2.12, 2.13 or 2.15 than the applicable Lender would have
been entitled to receive with respect to the participation sold to such
Participant, (i) unless the sale of the participation to such Participant is
made with the prior written consent of Borrower (which consent shall not be
unreasonably withheld or delayed) or (ii) except to the extent such entitlement
to a greater payment results from a Change in Law after such Participant became
a Participant. A Participant that would be a Foreign Lender if it were a Lender
shall not be entitled to the benefits of Section 2.15 unless Borrower is
notified of the participation sold to such Participant and such Participant
agrees, for the benefit of Borrower, to comply with Sections 2.15(e) and (f) as
though it were a Lender.

            (g) 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. In
the case of any Lender that is a fund that invests in bank loans, such Lender
may, without the consent of Borrower or the Administrative Agent, collaterally
assign or pledge all or any portion of its rights under this Agreement,
including the Loans and Notes or any other instrument evidencing its rights as a
Lender under this Agreement, to any holder of, trustee for, or any other
representative of holders of, obligations owed or securities issued, by such
fund, as security for such obligations or securities.

            SECTION 11.05 SURVIVAL OF AGREEMENT. All covenants, agreements,
representations and warranties made by the Loan Parties in the Loan Documents
and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the other parties hereto and shall survive the
execution and de-

                                     -111-
<PAGE>

livery of the Loan Documents and the making of any Loans and issuance of any
Letters of Credit, regardless of any investigation made by any such other party
or on its behalf and notwithstanding that the Agents, the Issuing Bank, the LC
Facility Issuing Bank or any Lender may have had notice or knowledge of any
Default or incorrect representation or warranty at the time any credit is
extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount
payable under this Agreement is outstanding and unpaid or any Letter of Credit
is outstanding and so long as the Commitments have not expired or terminated.
The provisions of Sections 2.12, 2.14, 2.15, 2.16 and 11.03 and Article X shall
survive and remain in full force and effect regardless of the consummation of
the transactions contemplated hereby, the repayment of the Loans, the payment of
the Reimbursement Obligations, the expiration or termination of the Letters of
Credit and the Commitments or the termination of this Agreement or any provision
hereof.

            SECTION 11.06 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract. This Agreement,
the other Loan Documents and the Fee Letter constitute the entire contract among
the parties relating to the subject matter hereof and supersede any and all
previous agreements and understandings, oral or written, relating to the subject
matter hereof. This Agreement shall become effective when it shall have been
executed by the Administrative Agent and when the Administrative Agent shall
have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

            SECTION 11.07 SEVERABILITY. Any provision of this Agreement held to
be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

            SECTION 11.08 RIGHT OF SETOFF. If an Event of Default shall have
occurred and be continuing, each Lender and each of its Affiliates are 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
Borrower against any and all of the obligations of 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. 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 11.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York, without regard to conflicts of law
principles that would require the application of the laws of another
jurisdiction.

            (b) Each Loan Party 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, in any action or proceeding arising out of or relating
to any Loan Document, 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

                                     -112-
<PAGE>

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 or any other Loan Document shall affect any right that
the Administrative Agent, the Issuing Bank, the LC Facility Issuing Bank or any
Lender may otherwise have to bring any action or proceeding relating to this
Agreement or any other Loan Document against any Loan Party or its properties in
the courts of any jurisdiction.

            (c) Each Loan Party 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 or any other Loan
Document in any court referred to in Section 11.09(b). 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.

            (d) Each party to this Agreement irrevocably consents to service of
process in any action or proceeding arising out of or relating to any Loan
Document, in the manner provided for notices (other than telecopy) in Section
11.01. Nothing in this Agreement or any other Loan Document will affect the
right of any party to this Agreement to serve process in any other manner
permitted by applicable law.

            SECTION 11.10 WAIVER OF JURY TRIAL. Each party hereto hereby waives,
to the fullest extent permitted by applicable law, any right it may have to a
trial by jury in any legal proceeding directly or indirectly arising out of or
relating to this Agreement, any other Loan Document or the transactions
contemplated hereby (whether based on contract, tort or any other theory). Each
party hereto (a) certifies that no representative, agent or attorney of any
other party has represented, expressly or otherwise, that such other party would
not, in the event of litigation, seek to enforce the foregoing waiver and (b)
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 Section.

            SECTION 11.11 HEADINGS. Article and Section headings and the Table
of Contents used herein are for convenience of reference only, are not part of
this Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

            SECTION 11.12 CONFIDENTIALITY. Each of the Administrative Agent, the
Issuing Bank, the LC Facility Issuing Bank 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' and affiliated
Approved Fund's 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
pursuant to the terms hereof), (b) to the extent requested by any regulatory
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,

charged, taken, received or reserved by the Lender holding such Loan in
accordance with applicable law, the rate of interest payable in respect of such
Loan hereunder, together with all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Loan but were not payable as a
result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be

together with interest thereon at the Federal Funds Effective Rate to the date
of repayment, shall have been received by such Lender.

            SECTION 11.14 LENDER ADDENDUM. Each Lender to become a party to this
Agreement on the date hereof shall do so by delivering to the Administrative

            SECTION 11.15 OBLIGATIONS ABSOLUTE. To the fullest extent permitted
by applicable law, all obligations of the Loan Parties hereunder shall be
absolute and unconditional irrespective of:

            (a) any bankruptcy, insolvency, reorganization, arrangement,
      readjustment, composition, liquidation or the like of any Loan Party;

            (b) any lack of validity or enforceability of any Loan Document or
      any other agreement or instrument relating thereto against any Loan Party;

            (c) any change in the time, manner or place of payment of, or in any

      remedy, power or privilege under or in respect hereof or any Loan
      Document; or

            (f) any other circumstances which might otherwise constitute a

      Anything in this Note to the contrary notwithstanding, the indebtedness
evidenced by this Note owed by any Payor that is Borrower or a Guarantor to any
Payee other than Borrower shall be subordinate and junior in right of payment,
to the extent and in the manner hereinafter set forth, to all Obligations of
such Payor under the Credit Agreement, including, without limitation, where
applicable, under such Payor's guarantee of the Obligations under the Credit
Agreement (such Obligations and other indebtedness and obligations in connection
with any renewal, refunding, restructuring or refinancing thereof, including
interest thereon accruing after the commencement of any proceedings referred to
in clause (i) below, whether or not such interest is an allowed claim in such
proceeding, being hereinafter collectively referred to as "SENIOR
INDEBTEDNESS"):

            (i) In the event of any insolvency or bankruptcy proceedings, and
      any receivership, liquidation, reorganization or other similar proceedings
      in connection therewith, relative to any Payor or to its creditors, as
      such, or to its property, and in the event of any proceedings for
      voluntary liquidation, dissolution or other winding up of such Payor,
      whether or not involving insolvency or bankruptcy, then (x) the holders of
      Senior Indebtedness shall be paid in full in cash in respect of all
      amounts constituting Senior Indebtedness before any Payee is entitled to
      receive (whether directly or indirectly), or make any demands for, any
      payment on account of this Note

                                       P-1
<PAGE>
      and (y) until the holders of Senior Indebtedness are paid in full in cash
      in respect of all amounts constituting Senior Indebtedness, any payment or
      distribution to which such Payee would otherwise be entitled (other than
      debt securities of such Payor that are subordinated, to at least the same
      extent as this Note, to the payment of all Senior Indebtedness then
      outstanding (such securities being hereinafter referred to as
      "RESTRUCTURED DEBT SECURITIES")) shall be made to the holders of Senior
      Indebtedness;

            (ii) if any event of default occurs and is continuing with respect
      to any Senior Indebtedness (including any Event of Default under the
      Credit Agreement), then no payment or distribution of any kind or
      character shall be made by or on behalf of the Payor or any other Person
      on its behalf with respect to this Note; and

            (iii) if any payment or distribution of any character, whether in
      cash, securities or other property (other than Restructured Debt
      Securities), in respect of this Note shall (despite these subordination
      provisions) be received by any Payee in violation of clause (i) or (ii)
      before all Senior Indebtedness shall have been paid in full in cash, such
      payment or distribution shall be held in trust for the benefit of, and
      shall be paid over or delivered to, the holders of Senior Indebtedness (or
      their representatives), ratably according to the respective aggregate
      amounts remaining unpaid thereon, to the extent necessary to pay all
      Senior Indebtedness in full in cash.

      To the fullest extent permitted by law, no present or future holder of
Senior Indebtedness shall be prejudiced in its right to enforce the
subordination of this Note by any act or failure to act on the part of any Payor
or by any act or failure to act on the part of such holder or any trustee or
agent for such holder. Each Payee and each Payor hereby agree that the
subordination of this Note is for the benefit of the Administrative Agent, the
Issuing Bank and the Lenders and the Administrative Agent, the Issuing Bank and
the Lenders are obligees under this Note to the same extent as if their names
were written herein as such and the Administrative Agent may, on behalf of the
itself, the Issuing Bank and the Lenders, proceed to enforce the subordination
provisions herein.

      The indebtedness evidenced by this Note owed by any Payor that is not
Borrower or a Guarantor shall not be subordinated to, and shall rank pari passu
in right of payment with, any other obligation of such Payor.

      Nothing contained in the subordination provisions set forth above is
intended to or will impair, as between each Payor and each Payee, the
obligations of such Payor, which are absolute and unconditional, to pay to such
Payee the principal of and interest on this Note as and when due and payable in
accordance with its terms, or is intended to or will affect the relative rights
of such Payee and other creditors of such Payor other than the holders of Senior
Indebtedness.

      Each Payee is hereby authorized to record all loans and advances made by
it to any Payor (all of which shall be evidenced by this Note), and all
repayments or prepayments thereof, in its books and records, such books and
records constituting prima facie evidence of the accuracy of the information
contained therein.

      Each Payor hereby waives presentment, demand, protest or notice of any
kind in connection with this Note. All payments under this Note shall be made
without offset, counterclaim or deduction of any kind.

            (a)   Letter of Credit Issuer agrees with each Revolver Lender that,

Outstanding Letter of Credit deemed sold to each Revolver Lender pursuant to
Section 2.1(b) of the Revolver Credit Agreement, and concurrently therewith, and

of the Revolver Credit Agreement, each such Revolver Lender shall be released
and discharged from all obligations to reimburse the Letter of Credit Issuer as
provided in Section 2.1(b) of the Revolver Credit Agreement and in any letter of
credit application.

            (b)   Borrower and each Restricted Subsidiary (as defined in the
Revolver Credit Agreement) for which an Outstanding Letter of Credit has been
issued agree that their reimbursement obligations relative to the Outstanding
Letters of Credit will survive the assignment of the Revolver Credit Agreement
pursuant to this Agreement and will continue in full force and effect and be
governed by the letter of credit applications relating to the Outstanding
Letters of Credit (which letter of credit applications shall remain in effect
notwithstanding any references therein to the Revolver Credit Agreement) until
such reimbursement obligations are paid in full or otherwise discharged.

            (c)   As collateral security for the Letter of Credit Exposure in
connection with the Outstanding Letters of Credit, the Borrower hereby grants to
the Letter of Credit Issuer a continuing security interest in the Cash
Collateral and the Cash Collateral Account to secure any reimbursement
obligation of any one or more of the Borrower, Bluestem and the Quest Pledgors
arising by reason of the honoring by the Letter of Credit Issuer of any drawing
under any of the Outstanding Letters of Credit. The Borrower acknowledges that
the Letter of Credit Issuer has "control" (within the meaning of Section 9-104
of the Uniform Commercial Code in effect in the State of Texas) over the Cash
Collateral Account and agrees that the Letter of Credit Issuer may exercise and
enforce with respect to the Cash Collateral and the Cash Collateral Account, in
addition to all rights and remedies otherwise available to the Letter of Credit
Issuer, all rights and remedies available to a secured party under the Uniform
Commercial Code in effect in the State of Texas. The Borrower agrees that it
will, at any time and from time to time, promptly execute and deliver all
further instruments and documents and take all further action that may be
necessary or that the Letter of Credit Issuer may reasonably request in order
(i) to perfect and protect the security interests in the Cash Collateral and the
Cash Collateral Account created or purported to be created hereby and the first
priority of such security interests; (ii) to enable the Letter of Credit Issuer
to exercise and enforce its rights and remedies hereunder and under the Uniform
Commercial Code in effect in the State of Texas in respect of the Cash
Collateral and the Cash Collateral Account; or (iii) to otherwise effect the
purposes of this Agreement, including authorizing and filing such financing or
continuation statements, or amendments thereto, as may be necessary or that the
Letter of Credit Issuer may reasonably request in order to perfect and preserve
the security interests in the Cash Collateral and the Cash Collateral Account
created or purported to be created hereby.

            (d)   Upon presentation to the Letter of Credit Issuer by any
Beneficiary of a draft for payment under any Outstanding Letter of Credit, the
Letter of Credit Issuer shall, and shall be entitled to, apply, concurrently
with its payment made in honor of such draft, such amount of the Cash
Collateral, up to the full amount thereof, as is necessary to satisfy the
reimbursement obligation arising by reason of its honoring of such draft.

            (e)   The Borrower hereby covenants and agrees that it will obtain
the original Outstanding Letters of Credit from the appropriate beneficiaries,
and will return such Outstanding Letters of Credit to the Letter of Credit
Issuer within 45 days of the Assignment Date.

                                        7

<PAGE>

            (f)   The Letter of Credit Issuer hereby covenants and agrees that,
upon receipt and cancellation of all Outstanding Letters of Credit, it will
promptly return to the Borrower the Cash Collateral (less (i) any Outstanding LC
Fees (defined below) then owed as provided herein, (ii) any portion thereof
applied to satisfy draw requests under Outstanding Letters of Credit as provided
above, and (iii) any fees owing to the Letter of Credit Issuer hereunder) and
release its liens and security interests in the Cash Collateral and the Cash
Collateral Account.

            (g)   The Letter of Credit Issuer shall have no obligation to invest
or pay interest on the Cash Collateral.

            (h)   The Borrower hereby covenants and agrees that if the original
outstanding Letters of Credit are not returned to the Letter of Credit Issuer in
accordance with Section 8(e) it will pay a fee (an "Outstanding LC Fee") in an
amount equal to three-tenths of one percent (.30%) of the stated amounts of the
Outstanding Letters of Credit on each Quarterly Date (as defined in the Revolver
Credit Agreement).

      9.    Preservation of Liens and Security Interests. Except as expressly
set forth in Section 1 above with respect to the Released Collateral, nothing
contained herein shall be deemed to release, modify or impair the liens or
security interests in the Collateral comprising the Assigned Rights in any
respect, all of which shall continue to secure the obligations and indebtedness
under the New Credit Agreement, including, without limitation, the Obligations
(as defined in the New Credit Agreement) and all of which liens and security
interests are hereby ratified and confirmed. The Borrower hereby acknowledges
that the New Credit Agreement represents a renewal, extension, amendment and
modification of the Existing Debt, but does not represent a satisfaction or
novation thereof. Upon receipt of each original Revolver Note from the
applicable Revolver Lender, the New Agent shall mark such Revolver Note
"replaced" and promptly return such Revolver Note to the Borrower.

      10.   Miscellaneous. This Agreement shall be governed by and construed
under the laws of the State of Texas and shall be binding upon and inure to the
benefit of the parties hereto and their successors and assigns. This Agreement
may be executed in any number of counterparts, each of which shall be an
original, but all of which together shall constitute one instrument. Facsimiles
shall be effective as originals.

      11.   JURY WAIVER. THE PARTIES HERETO HEREBY WAIVE, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDINGS ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.
