                                CREDIT AGREEMENT

      This CREDIT AGREEMENT ("Agreement") is entered into as of February 10,
2005, among AMR HOLDCO, INC., a Delaware corporation ("AMR Holdco"), EMCARE
HOLDCO, INC., a Delaware corporation ("EmCare Holdco"; each of AMR Holdco and

"Lenders" and individually, a "Lender"), and BANK OF AMERICA, N.A., as

      Pursuant to the Purchase Agreements, the Equity Investors have agreed to

Equity (as defined below)) of each of the Borrowers from their existing
shareholders (the "Sellers"). In connection with the Acquisition, the Equity
Investors will make a cash contribution of not less than $215,000,000 to the
common equity of Holdings, which will in turn contribute such amount to the
Borrowers (the "Equity Contribution"), and the Borrowers will issue senior
subordinated unsecured notes yielding gross cash proceeds of $250,000,000.

      The Borrowers and Holdings have requested that (a) immediately prior to
the consummation of the Acquisition, the Term Loan Lenders make Term Loans to
the Borrowers in an aggregate principal amount of $350,000,000 to pay a portion
of the cash consideration required to consummate the Acquisition, to refinance
certain existing indebtedness of the Borrowers and to pay fees and expenses
incurred in connection with the Transactions and (b) from time to time, the
Revolving Loan Lenders lend to the Borrowers and the L/C Issuer issue Letters of
Credit for the account of the Borrowers under a $100,000,000 revolving credit
facility for the Borrowers.

      The applicable Lenders have indicated their willingness to lend and the
L/C Issuer has indicated its willingness to so issue Letters of Credit, in each
case, on the terms and subject to the conditions set forth herein.

      In consideration of the mutual covenants and agreements herein contained,
the parties hereto covenant and agree as follows:

                                    ARTICLE I

time, applied in a manner consistent with that used in preparing the Audited
Financial Statements, except as otherwise specifically prescribed herein.

      (b) Changes in GAAP. If at any time any change in GAAP would affect the
computation of any financial ratio or requirement set forth in any Loan
Document, and either the Borrowers or the Required Lenders shall so request, the
Administrative Agent, the Lenders and the Borrowers shall negotiate in good
faith to amend such ratio or requirement to preserve the original intent thereof

Lenders); provided that, until so amended, (i) such ratio or requirement shall
continue to be computed in accordance with GAAP prior to such change therein and

                      THE COMMITMENTS AND CREDIT EXTENSIONS

      2.01 TERM LOANS AND REVOLVING LOANS.

      (a) Term Loans. Subject to the terms and conditions set forth herein, each
Term Loan Lender severally agrees to make a loan (each such loan, a "Term Loan")
to the Borrowers on the Closing Date, in the amount of such Term Loan Lender's
Term Loan Commitment. Amounts borrowed as Term Loans under this Section 2.01(a)
and subsequently repaid or prepaid may not be reborrowed. Term Loans may be Base
Rate Loans or Eurodollar Rate Loans, as further provided herein.

      (b) Revolving Loans. Subject to the terms and conditions set forth herein,
each Revolving Loan Lender severally agrees to make loans (each such loan, a
"Revolving Loan") to the Borrowers from time to time, on any Business Day during
the Availability Period, in an aggregate amount not to exceed at any time
outstanding the amount of such Revolving Loan Lender's Revolving Loan
Commitment; provided that after giving effect to any Revolving Loan Borrowing,
the aggregate Outstanding Amount of the Revolving Loans of any Lender, plus such

                                      -40-
<PAGE>

Lender's Pro Rata Share of the Outstanding Amount of all L/C Obligations, plus
such Lender's Pro Rata Share of the Outstanding Amount of all Swing Line Loans
shall not exceed such Lender's Revolving Loan Commitment. Within the limits of
each Lender's Revolving Loan Commitment, and subject to the other terms and
conditions hereof, the Borrowers may borrow under this Section 2.01(b), prepay
under Section 2.05, and reborrow under this Section 2.01(b). Revolving Loans may
be Base Rate Loans or Eurodollar Rate Loans, as further provided herein.

      2.02 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF REVOLVING LOANS AND TERM
LOANS.

      (a) Each Revolving Loan Borrowing, the Term Loan Borrowing, each
conversion of Revolving Loans from one Type to the other, each conversion of
Term Loans from one type to the other, and each continuation of Eurodollar Rate
Loans shall be made upon the Borrowers' irrevocable notice to the Administrative
Agent, which may be given by telephone. Each such notice must be received by the
Administrative Agent not later than (i) 1:00 p.m. three Business Days prior to
the requested date of any Borrowing of, conversion to or continuation of
Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base Rate
Loans, and (ii) 12:00 noon on the requested date of any Borrowing of Base Rate
Loans; provided that if a Borrower wishes to request Eurodollar Rate Loans
having an Interest Period other than one, two, three or six or, if available to
all Lenders, nine or twelve months, in duration as provided in the definition of
"Interest Period," the applicable notice must be received by the Administrative
Agent not later than 1:00 p.m. four Business Days prior to the requested date of
such Borrowing, conversion or continuation, whereupon the Administrative Agent
shall give prompt notice to the Lenders of such request and determine whether
the requested Interest Period is acceptable to all of them. Not later than 1:00
p.m., three Business Days before the requested date of such Borrowing,
conversion or continuation, the Administrative Agent shall notify the applicable
Borrower (which notice may be by telephone) whether or not the requested
Interest Period has been consented to by all the Lenders. Each telephonic notice
by the applicable Borrower pursuant to this Section 2.02(a) must be confirmed
promptly by delivery to the Administrative Agent of a written Committed Loan
Notice, appropriately completed and signed by a Responsible Officer of the
applicable Borrower. Each Borrowing of, conversion to or continuation of
Eurodollar Rate Loans shall be in a principal amount of $2,000,000 or a whole
multiple of $500,000 in excess thereof. Except as provided in Sections 2.03(c)
and 2.04(c), each Borrowing of or conversion to Base Rate Loans shall be in a
principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.
Each Committed Loan Notice (whether telephonic or written) shall specify (i)
whether the applicable Borrower is requesting a Revolving Loan Borrowing, a Term
Loan Borrowing, a conversion of Revolving Loans from one Type to the other, a
conversion of Term Loans from one type to the other, or a continuation of
Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or
continuation, as the case may be (which shall be a Business Day), (iii) the
principal amount of Revolving Loans or Term Loans to be borrowed, converted or
continued, (iv), if applicable, the Type of Revolving Loans to be borrowed or to
which existing Revolving Loans are to be converted, (v) if applicable, the type
of Term Loans to be borrowed or to which existing Term Loans are to be
converted, and (vi) if applicable, the duration of the Interest Period with
respect thereto. If the applicable Borrower fails to specify a Type of Loan in a
Committed Loan Notice or if the applicable Borrower fails to give a timely
notice requesting a conversion or continuation, then the applicable Revolving
Loans or Term Loans, as the case may be, shall be made as, or converted to, Base
Rate Loans. Any such automatic conversion to Base

                                      -41-
<PAGE>

Rate Loans shall be effective as of the last day of the Interest Period then in
effect with respect to the applicable Eurodollar Rate Loans. If the applicable
Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar
Rate Loans in any such Committed Loan Notice, but fails to specify an Interest
Period, it will be deemed to have specified an Interest Period of one month.

      (b) Following receipt of a Committed Loan Notice, the Administrative Agent
shall promptly notify each Appropriate Lender of the amount of its Pro Rata
Share of the applicable Class of Loans, and if no timely notice of a conversion
or continuation is provided by the applicable Borrower, the Administrative Agent
shall notify each Lender of the details of any automatic conversion to Base Rate
Loans or continuation described in Section 2.02(a). In the case of each
Borrowing, each Appropriate Lender shall make the amount of its Loan available
to the Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 2:00 p.m. on the Business Day specified in the
applicable Committed Loan Notice. Upon satisfaction of the applicable conditions
set forth in Section 4.02 (and, if such Borrowing is the initial Credit
Extension, Section 4.01), the Administrative Agent shall make all funds so
received available to the applicable Borrower in like funds as received by the
Administrative Agent either by (i) crediting the account of the applicable
Borrower on the books of Bank of America with the amount of such funds or (ii)
wire transfer of such funds, in each case in accordance with instructions
provided to (and reasonably acceptable to) the Administrative Agent by the
applicable Borrower; provided that if, on the date the Committed Loan Notice
with respect to such Borrowing is given by the applicable Borrower, there are
Swing Line Loans or L/C Borrowings outstanding, then the proceeds of such
Borrowing shall be applied, first, to the payment in full of any such L/C
Borrowings, second, to the payment in full of any such Swing Line Loans, and
third, to the applicable Borrower as provided above.

      (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be
continued or converted only on the last day of an Interest Period for such
Eurodollar Rate Loan. During the existence of an Event of Default, no Revolving
Loans may be requested as, converted to or continued as Eurodollar Rate Loans
without the consent of the Required Lenders and no Term Loans may be requested
as, converted to or continued as Eurodollar Rate Term Loans without the consent
of the Required Lenders.

      (d) The Administrative Agent shall promptly notify the applicable Borrower
and the applicable Lenders of the interest rate applicable to any Interest
Period for Eurodollar Rate Loans upon determination of such interest rate. At
any time that Base Rate Loans are outstanding, the Administrative Agent shall
notify the applicable Borrower and the Lenders of any change in Bank of
America's prime rate used in determining the Base Rate promptly following the
public announcement of such change.

      (e) After giving effect to all Borrowings, all conversions of Loans from
one Type to the other, and all continuations of Loans as the same Type, there
shall not be more than twelve Interest Periods in effect with respect to Loans.

                                      -42-

      2.03 LETTERS OF CREDIT.

      (a) The Letter of Credit Commitment.

            (i) Subject to the terms and conditions set forth herein, (A) the
      L/C Issuer agrees, in reliance upon the agreements of the Revolving Loan
      Lenders set forth in this Section 2.03, (1) from time to time on any
      Business Day during the period from the Closing Date until the Letter of
      Credit Expiration Date, to issue Letters of Credit for the account of the
      applicable Borrower and to amend or extend Letters of Credit previously
      issued by it, in accordance with subsection (b) below, and (2) to honor
      drawings under the Letters of Credit; and (B) the Revolving Loan Lenders
      severally agree to participate in Letters of Credit issued for the account
      of the applicable Borrower and any drawings thereunder; provided that
      after giving effect to any L/C Credit Extension with respect to any Letter
      of Credit, (x) the aggregate Outstanding Amount of the Revolving Loans of
      any Lender, plus such Lender's Pro Rata Share of the Outstanding Amount of
      all L/C Obligations, plus such Lender's Pro Rata Share of the Outstanding
      Amount of all Swing Line Loans would exceed such Lender's Revolving Loan
      Commitment or (y) the Outstanding Amount of the L/C Obligations would
      exceed the Letter of Credit Sublimit. Within the foregoing limits, and
      subject to the terms and conditions hereof, the Borrowers' ability to
      obtain Letters of Credit shall be fully revolving, and accordingly the
      Borrowers may, during the foregoing period, obtain Letters of Credit to
      replace Letters of Credit that have expired or that have been drawn upon
      and reimbursed.

            (ii) The L/C Issuer shall not issue any Letter of Credit, if:

                  (A) the expiry date of such requested Letter of Credit would
            occur more than twelve months after the date of issuance, unless the
            Revolving Loan Lenders have approved such expiry date; or

                  (B) the expiry date of such requested Letter of Credit would
            occur after the Letter of Credit Expiration Date, unless all the
            Revolving Loan Lenders have approved such expiry date.

            (iii) The L/C Issuer shall not be under any obligation to issue any
      Letter of Credit if:

                  (A) any order, judgment or decree of any Governmental
            Authority or arbitrator shall by its terms purport to enjoin or
            restrain the L/C Issuer from issuing such Letter of Credit, or any
            Law applicable to the L/C Issuer or any request or directive
            (whether or not having the force of law) from any Governmental
            Authority with jurisdiction over the L/C Issuer shall prohibit, or
            request that the L/C Issuer refrain from, the issuance of letters of
            credit generally or such Letter of Credit in particular or shall
            impose upon the L/C Issuer with respect to such Letter of Credit any
            restriction, reserve or capital requirement (for which the L/C
            Issuer is not otherwise compensated hereunder) not in effect on the
            Closing Date, or shall impose upon the L/C Issuer any unreimbursed
            loss, cost or expense which

                                      -43-
<PAGE>

            was not applicable on the Closing Date and which the L/C Issuer in
            good faith deems material to it;

                  (B) the issuance of such Letter of Credit would violate one or
            more policies of the L/C Issuer;

                  (C) except as otherwise agreed by the Administrative Agent and
            the L/C Issuer, such Letter of Credit is in an initial stated amount
            less than $50,000;

                  (D) such Letter of Credit is to be denominated in a currency
            other than Dollars;

                  (E) such Letter of Credit contains any provisions for
            automatic reinstatement of the stated amount after any drawing
            thereunder; or

                  (F) a default of any Revolving Loan Lender's obligations to
            fund under Section 2.03(c) exists or any Revolving Loan Lender is at
            such time a Defaulting Lender hereunder, unless (i) the L/C Issuer
            has entered into satisfactory arrangements with the Borrowers or
            such Revolving Loan Lender to eliminate the L/C Issuer's risk with
            respect to such Revolving Loan Lender or (ii) the Borrowers shall
            have Cash Collateralized for the benefit of the L/C Issuer the full
            portion of such defaulting Lender's pro rata portion of such Letter
            of Credit.

            (iv) The L/C Issuer shall not amend any Letter of Credit if the L/C
      Issuer would not be permitted at such time to issue such Letter of Credit
      in its amended form under the terms hereof.

            (v) The L/C Issuer shall be under no obligation to amend any Letter
      of Credit if (A) the L/C Issuer would have no obligation at such time to
      issue such 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.

            (vi) The L/C Issuer shall act on behalf of the Revolving Loan
      Lenders with respect to any Letters of Credit issued by it and the
      documents associated therewith, and the L/C Issuer shall have all of the
      benefits and immunities (A) provided to the Administrative Agent in
      Article IX with respect to any acts taken or omissions suffered by the L/C
      Issuer in connection with Letters of Credit issued by it or proposed to be
      issued by it and Issuer Documents pertaining to such Letters of Credit as
      fully as if the term "Administrative Agent" as used in Article IX included
      the L/C Issuer with respect to such acts or omissions, and (B) as
      additionally provided herein with respect to the L/C Issuer.

      (b) Procedures for Issuance and Amendment of Letters of Credit.

            (i) Each Letter of Credit shall be issued or amended, as the case
      may be, upon the request of the applicable Borrower delivered to the L/C
      Issuer (with a copy to the Administrative Agent) in the form of a Letter
      of Credit Application, appropriately completed and signed by a Responsible
      Officer of such Borrower. Such Letter of Credit Application must be
      received by the L/C Issuer and the Administrative Agent not later than

                                      -44-
<PAGE>

      1:00 p.m. at least two Business Days (or such later date and time as the
      Administrative Agent and the L/C Issuer may agree in a particular instance
      in their sole discretion) prior to the proposed issuance date or date of
      amendment, as the case may be. In the case of a request for an initial
      issuance of a Letter of Credit, such Letter of Credit Application shall
      specify in form and detail reasonably satisfactory to the L/C Issuer: (A)
      the proposed issuance date of the requested Letter of Credit (which shall
      be a Business Day); (B) the amount thereof; (C) the expiry date thereof;
      (D) the name and address of the beneficiary thereof; (E) the documents to
      be presented by such beneficiary in case of any drawing thereunder; (F)
      the full text of any certificate to be presented by such beneficiary in
      case of any drawing thereunder; and (G) such other matters as the L/C
      Issuer may require. In the case of a request for an amendment of any
      outstanding Letter of Credit, such Letter of Credit Application shall
      specify in form and detail reasonably satisfactory to the L/C Issuer (A)
      the Letter of Credit to be amended; (B) the proposed date of amendment
      thereof (which shall be a Business Day); (C) the nature of the proposed
      amendment; and (D) such other matters as the L/C Issuer may require.
      Additionally, the applicable Borrower shall furnish to the L/C Issuer and
      the Administrative Agent such other documents and information pertaining
      to such requested Letter of Credit issuance or amendment, including any
      Issuer Documents, as the L/C Issuer or the Administrative Agent may
      require.

            (ii) Promptly after receipt of any Letter of Credit Application, the
      L/C Issuer will confirm with the Administrative Agent (by telephone or in
      writing) that the Administrative Agent has received a copy of such Letter
      of Credit Application from the applicable Borrower and, if not, the L/C
      Issuer will provide the Administrative Agent with a copy thereof. Unless
      the L/C Issuer has received written notice from any Revolving Loan Lender,
      the Administrative Agent or any Loan Party, at least one Business Day
      prior to the requested date of issuance or amendment of the applicable
      Letter of Credit, that one or more applicable conditions contained in
      Article IV in the case of an issuance on the Closing Date or Section 4.02
      in the case of any issuance thereafter shall not then be satisfied, then,
      subject to the terms and conditions hereof, the L/C Issuer shall, on the
      requested date, issue a Letter of Credit for the account of the applicable
      Borrower or enter into the applicable amendment, as the case may be, in
      each case in accordance with the L/C Issuer's usual and customary business
      practices. Immediately upon the issuance of each Letter of Credit, each
      Lender shall be deemed to, and hereby irrevocably and unconditionally
      agrees to, purchase from the L/C Issuer a risk participation in such
      Letter of Credit in an amount equal to the product of such Revolving
      Lender's Pro Rata Share times the amount of such Letter of Credit.

            (iii) Promptly after its delivery of any Letter of Credit or any
      amendment to a Letter of Credit to an advising bank with respect thereto
      or to the beneficiary thereof, the L/C Issuer will also deliver to the
      applicable Borrower and the Administrative Agent a true and complete copy
      of such Letter of Credit or amendment.

      (c) Drawings and Reimbursements; Funding of Participations.

            (i) Upon receipt from the beneficiary of any Letter of Credit of any
      notice in accordance with such Letter of Credit of a drawing under such
      Letter of Credit, the L/C Issuer shall notify the applicable Borrower and
      the Administrative Agent thereof. Not

                                      -45-
<PAGE>

      later than 1:00 p.m. on the date of any payment by the L/C Issuer under a
      Letter of Credit (each such date, an "Honor Date"), the Borrowers shall
      reimburse the L/C Issuer through the Administrative Agent in an amount
      equal to the amount of such drawing. If the Borrowers fail to so reimburse
      the L/C Issuer by such time, the Administrative Agent shall promptly
      notify each Revolving Loan Lender of the Honor Date, the amount of the
      unreimbursed drawing (the "Unreimbursed Amount"), and the amount of such
      Revolving Loan Lender's Pro Rata Share thereof. In such event, the
      applicable Borrower shall be deemed to have requested a Revolving Loan
      Borrowing of Base Rate Loans to be disbursed on the Honor Date in an
      amount equal to the Unreimbursed Amount, without regard to the minimum and
      multiples specified in Section 2.02 for the principal amount of Base Rate
      Loans, but subject to the amount of the unutilized portion of the
      Aggregate Revolving Loan Commitments and the conditions set forth in
      Section 4.02 (other than the delivery of a Committed Loan Notice). Any
      notice given by the L/C Issuer or the Administrative Agent pursuant to
      this Section 2.03(c)(i) may be given by telephone if immediately confirmed
      in writing; provided that the lack of such an immediate confirmation shall
      not affect the conclusiveness or binding effect of such notice.

            (ii) Each Revolving Loan Lender shall upon any notice pursuant to
      Section 2.03(c)(i) make funds available to the Administrative Agent for
      the account of the L/C Issuer at the Administrative Agent's Office in an
      amount equal to its Pro Rata Share of the Unreimbursed Amount not later
      than 2:00 p.m. on the Business Day specified in such notice by the
      Administrative Agent, whereupon, subject to the provisions of Section
      2.03(c)(iii), each Revolving Loan Lender that so makes funds available
      shall be deemed to have made a Base Rate Revolving Loan to the applicable
      Borrower in such amount. The Administrative Agent shall remit the funds so
      received to the L/C Issuer.

            (iii) With respect to any Unreimbursed Amount that is not fully
      refinanced by a Revolving Loan Borrowing of Base Rate Loans because the
      conditions set forth in Section 4.02 cannot be satisfied or for any other
      reason, the applicable Borrower shall be deemed to have incurred from the
      L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that
      is not so refinanced, which L/C Borrowing shall be due and payable on
      demand (together with interest) and shall bear interest at the Default
      Rate. In such event, each Revolving Loan Lender's payment to the
      Administrative Agent for the account of the L/C Issuer pursuant to Section
      2.03(c)(ii) shall be deemed payment in respect of its participation in
      such L/C Borrowing and shall constitute an L/C Advance from such Revolving
      Loan Lender in satisfaction of its participation obligation under this
      Section 2.03.

            (iv) Until each Revolving Loan Lender funds its Revolving Loan or
      L/C Advance pursuant to this Section 2.03(c) to reimburse the L/C Issuer
      for any amount drawn under any Letter of Credit, interest in respect of
      such Revolving Loan Lender's Pro Rata Share of such amount shall be solely
      for the account of the L/C Issuer.

            (v) Each Revolving Loan Lender's obligation to make Revolving Loans
      or L/C Advances to reimburse the L/C Issuer for amounts drawn under
      Letters of Credit, as contemplated by this Section 2.03(c), shall be
      absolute and unconditional and shall not be affected by any circumstance,
      including (A) any setoff, counterclaim, recoupment,

                                      -46-
<PAGE>

      defense or other right which such Revolving Loan Lender may have against
      the L/C Issuer, the Borrowers or any other Person for any reason
      whatsoever; (B) the occurrence or continuance of a Default, or (C) any
      other occurrence, event or condition, whether or not similar to any of the
      foregoing; provided that each Revolving Loan Lender's obligation to make
      Revolving Loans pursuant to this Section 2.03(c) is subject to the
      conditions set forth in Section 4.02 (other than delivery by the
      applicable Borrower of a Committed Loan Notice). No such making of an L/C
      Advance shall relieve or otherwise impair the obligation of the Borrowers
      to reimburse the L/C Issuer for the amount of any payment made by the L/C
      Issuer under any Letter of Credit, together with interest as provided
      herein.

            (vi) If any Lender fails to make available to the Administrative
      Agent for the account of the L/C Issuer any amount required to be paid by
      such Revolving Loan Lender pursuant to the foregoing provisions of this
      Section 2.03(c) by the time specified in Section 2.03(c)(ii), the L/C
      Issuer shall be entitled to recover from such Lender (acting through the
      Administrative Agent), on demand, such amount with interest thereon for
      the period from the date such payment is required to the date on which
      such payment is immediately available to the L/C Issuer at a rate per
      annum equal to the greater of the Federal Funds Rate and a rate determined
      by the L/C Issuer in accordance with banking industry rules on interbank
      compensation. A certificate of the L/C Issuer submitted to any Revolving
      Loan Lender (through the Administrative Agent) with respect to any amounts
      owing under this clause (vi) shall be conclusive absent manifest error.

      (d) Repayment of Participations.

            (i) At any time after the L/C Issuer has made a payment under any
      Letter of Credit and has received from any Revolving Loan Lender such
      Revolving Loan Lender's L/C Advance in respect of such payment in
      accordance with Section 2.03(c), if the Administrative Agent receives for
      the account of the L/C Issuer any payment in respect of the related
      Unreimbursed Amount or interest thereon (whether directly from the
      Borrowers or otherwise, including proceeds of cash collateral applied
      thereto by the Administrative Agent), the Administrative Agent will
      distribute to such Revolving Loan Lender its Pro Rata Share thereof
      (appropriately adjusted, in the case of interest payments, to reflect the
      period of time during which such Revolving Loan Lender's L/C Advance was
      outstanding) in the same funds as those received by the Administrative
      Agent.

            (ii) If any payment received by the Administrative Agent for the
      account of the L/C Issuer pursuant to Section 2.03(c)(i) is required to be
      returned under any of the circumstances described in Section 10.05
      (including pursuant to any settlement entered into by the L/C Issuer in
      its discretion), each Revolving Loan Lender shall pay to the
      Administrative Agent for the account of the L/C Issuer its Pro Rata Share
      thereof on demand of the Administrative Agent, plus interest thereon from
      the date of such demand to the date such amount is returned by such
      Revolving Loan Lender, at a rate per annum equal to the Federal Funds Rate
      from time to time in effect. The obligations of the Revolving Loan Lenders
      under this clause shall survive the payment in full of the Obligations and
      the termination of this Agreement.

                                      -47-
<PAGE>

      (e) Obligations Absolute. The joint and several obligations of the
Borrowers to reimburse the L/C Issuer for each drawing under each Letter of
Credit and to repay each L/C Borrowing shall be absolute, unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including the following:

            (i) any lack of validity or enforceability of such Letter of Credit,
      this Agreement, or any other Loan Document;

            (ii) the existence of any claim, counterclaim, setoff, defense or
      other right that the Borrowers or any Subsidiary may have at any time
      against any beneficiary or any transferee of such Letter of Credit (or any
      Person for whom any such beneficiary or any such transferee may be
      acting), the L/C Issuer or any other Person, whether in connection with
      this Agreement, the transactions contemplated hereby or by such Letter of
      Credit or any agreement or instrument relating thereto, or any unrelated
      transaction;

            (iii) any draft, demand, certificate or other document presented
      under such Letter of Credit proving to be forged, fraudulent, invalid or
      insufficient in any respect or any statement therein being untrue or
      inaccurate in any respect; or any loss or delay in the transmission or
      otherwise of any document required in order to make a drawing under such
      Letter of Credit;

            (iv) any payment by the L/C Issuer under such Letter of Credit
      against presentation of a draft or certificate that does not strictly
      comply with the terms of such Letter of Credit; or any payment made by the
      L/C Issuer under such Letter of Credit to any Person purporting to be a
      trustee in bankruptcy, debtor-in-possession, assignee for the benefit of
      creditors, liquidator, receiver or other representative of or successor to
      any beneficiary or any transferee of such Letter of Credit, including any
      arising in connection with any proceeding under any Debtor Relief Law;

            (v) any exchange, release or nonperfection of any Collateral, or any
      release or amendment or waiver of or consent to departure from the
      Guaranty or any other guarantee, for all or any of the Obligations of the
      Borrowers in respect of such Letter of Credit; or

            (vi) any other circumstance or happening whatsoever, whether or not
      similar to any of the foregoing, including any other circumstance that
      might otherwise constitute a defense available to, or a discharge of, the
      Borrowers or any Subsidiary.

      The applicable Borrower shall promptly examine a copy of each Letter of
Credit and each amendment thereto that is delivered to it and, in the event of
any claim of noncompliance with the applicable Borrower's instructions or other
irregularity, the applicable Borrower will promptly notify the L/C Issuer. The
applicable Borrower shall be conclusively deemed to have waived any such claim
against the L/C Issuer and its correspondents unless such notice is given as
aforesaid.

      (f) Role of L/C Issuer. Each Revolving Loan Lender and the Borrowers agree
that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not
have any responsibility to obtain any document (other than any sight draft,
certificates and documents expressly required

                                      -48-
<PAGE>

by the Letter of Credit) or to ascertain or inquire as to the validity or
accuracy of any such document or the authority of the Person executing or
delivering any such document. None of the L/C Issuer, the Administrative Agent,
any of their respective Related Parties nor any correspondent, participant or
assignee of the L/C Issuer shall be liable to any Revolving Loan Lender for (i)
any action taken or omitted in connection herewith at the request or with the
approval of the Revolving Loan Lenders, the Required Revolving Loan Lenders or
any Required Lenders, as applicable; (ii) any action taken or omitted in the
absence of gross negligence or willful misconduct; or (iii) the due execution,
effectiveness, validity or enforceability of any document or instrument related
to any Letter of Credit or Issuer Document. The Borrowers hereby assume all
risks of the acts or omissions of any beneficiary or transferee with respect to
its use of any Letter of Credit; provided that this assumption is not intended
to, and shall not, preclude the Borrowers' pursuing such rights and remedies as
it may have against the beneficiary or transferee at law or under any other
agreement. None of the L/C Issuer, the Administrative Agent, any of their
respective Related Parties nor any correspondent, participant or assignee of the
L/C Issuer shall be liable or responsible for any of the matters described in
clauses (i) through (vi) of Section 2.03(e); provided that anything in such
clauses to the contrary notwithstanding, the Borrowers may have a claim against
the L/C Issuer, and the L/C Issuer may be liable to the Borrowers, to the
extent, but only to the extent, of any direct, as opposed to consequential or
exemplary, damages suffered by the Borrowers which the Borrowers prove were
caused by the L/C Issuer's willful misconduct or gross negligence or the L/C
Issuer's willful failure to pay under any Letter of Credit after the
presentation to it by the beneficiary of a sight draft and certificate(s)
strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing, the L/C Issuer may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary,
and the L/C Issuer shall not be responsible for the validity or sufficiency of
any instrument transferring or assigning or purporting to transfer or assign a
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason.

      (g) Cash Collateral. Upon the request of the Administrative Agent, (i) if
the L/C Issuer has honored any full or partial drawing request under any Letter
of Credit and such drawing has resulted in an L/C Borrowing or (ii) if, as of
the Letter of Credit Expiration Date, any L/C Obligation for any reason remains
outstanding, the Borrowers shall, in each case, (a) immediately Cash
Collateralize the then Outstanding Amount of all L/C Obligations or (b) in
accordance with and on terms acceptable to the L/C Issuer, in its sole
discretion, post a supporting letter of credit. Sections 2.05 and 8.02(c) set
forth certain additional requirements to deliver Cash Collateral hereunder. For
purposes of this Section 2.03, Section 2.05 and Section 8.02(c), "Cash
Collateralize" means to pledge and deposit with or deliver to the Administrative
Agent, for the benefit of the L/C Issuer and the Revolving Loan Lenders, as
collateral for the L/C Obligations, cash or deposit account balances pursuant to
documentation in form and substance reasonably satisfactory to the
Administrative Agent and the L/C Issuer (which documents are hereby consented to
by the Revolving Loan Lenders). Derivatives of such term have corresponding
meanings. The Borrowers hereby grant to the Administrative Agent, for the
benefit of the L/C Issuer and the Revolving Loan Lenders, a security interest in
all such cash, deposit accounts and all balances therein and all proceeds of the
foregoing. Cash Collateral shall be maintained in blocked interest-bearing
deposit accounts at Bank of America.

                                      -49-

      (h) Applicability of ISP. Unless otherwise expressly agreed by the L/C
Issuer and the applicable Borrower when a Letter of Credit is issued (including
any such agreement applicable to an Existing Letter of Credit), the rules of the
ISP shall apply to each Letter of Credit.

      (i) Letter of Credit Fees. The applicable Borrower shall pay to the
Administrative Agent for the account of each Lender (other than a Defaulting
Lender, which portion shall be paid to the L/C Issuer) in accordance with its
Pro Rata Share a Letter of Credit fee (the "Letter of Credit Fee") for each
Letter of Credit equal to the Applicable Rate then in effect for Revolving Loans
bearing interest at the Eurodollar Rate times the daily amount available to be
drawn under such Letter of Credit. Letter of Credit Fees shall be (i) computed
on a quarterly basis in arrears and (ii) due and payable on the first Business
Day after the end of each February, May, August and November, commencing with
the first such date to occur after the issuance of such Letter of Credit (or, in
the case of Letters of Credit issued prior to March 1, 2005, commencing with May
31, 2005), on the Letter of Credit Expiration Date and thereafter on demand. If
there is any change in the Applicable Rate during any quarter, the daily amount
available to be drawn under each Letter of Credit shall be computed and
multiplied by the Applicable Rate separately for each period during such quarter
that such Applicable Rate was in effect. Notwithstanding anything to the
contrary contained herein, upon the request of the Required Lenders, while any
payment Event of Default exists, all Letter of Credit Fees shall accrue at the
Default Rate.

      (j) Fronting Fee and Documentary and Processing Charges Payable to L/C
Issuer. The applicable Borrower shall pay directly to the L/C Issuer for its own
account a fronting fee with respect to each Letter of Credit, at the rate per
annum equal to 0.125%, computed on the daily amount available to be drawn under
such Letter of Credit on a quarterly basis in arrears, and due and payable on
the first Business Day after the end of each February, May, August and November,
commencing with the first such date to occur after the issuance of such Letter
of Credit, on the Letter of Credit Expiration Date and thereafter on demand. In
addition, the applicable Borrower shall pay directly to the L/C Issuer for its
own account the customary issuance, presentation, amendment and other processing
fees, and other standard costs and charges, of the L/C Issuer relating to
letters of credit as from time to time in effect. Such customary fees and
standard costs and charges are due and payable on demand and are nonrefundable.

      (k) Conflict with Issuer Documents. In the event of any conflict between
the terms hereof and the terms of any Issuer Document, the terms hereof shall
control.

      2.04 SWING LINE LOANS.

      (a) The Swing Line. Subject to the terms and conditions set forth herein,
the Swing Line Lender agrees, in reliance upon the agreements of the other
Revolving Loan Lenders set forth in this Section 2.04, to make loans (each such
loan, a "Swing Line Loan") to the Borrowers from time to time on any Business
Day during the Availability Period in an aggregate amount not to exceed at any
time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact
that such Swing Line Loans, when aggregated with the Pro Rata Share of the
Outstanding Amount of Revolving Loans and L/C Obligations of the Revolving Loan
Lender acting as Swing Line Lender, may exceed the amount of such Revolving Loan
Lender's Commitment; provided that after giving effect to any Swing Line Loan,
(i) the Outstanding Amount of Revolving Loans shall not exceed the Aggregate
Revolving Loan Commitments, and (ii) the aggregate

                                      -50-
<PAGE>

Outstanding Amount of the Revolving Loans of any Revolving Loan Lender, plus
such Revolving Loan Lender's Pro Rata Share of the Outstanding Amount of all L/C
Obligations, plus such Revolving Loan Lender's Pro Rata Share of the Outstanding
Amount of all Swing Line Loans shall not exceed such Revolving Loan Lender's
Commitment, and provided, further, that the Borrowers shall not use the proceeds
of any Swing Line Loan to refinance any outstanding Swing Line Loan. Within the
foregoing limits, and subject to the other terms and conditions hereof, the
Borrowers may borrow under this Section 2.04, prepay under Section 2.05, and
reborrow under this Section 2.04. Each Swing Line Loan shall be a Base Rate
Loan. Immediately upon the making of a Swing Line Loan, each Revolving Loan
Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from the Swing Line Lender a risk participation in such Swing Line Loan
in an amount equal to the product of such Revolving Loan Lender's Pro Rata Share
times the amount of such Swing Line Loan.

      (b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the
applicable Borrower's irrevocable notice to the Swing Line Lender and the
Administrative Agent, which may be given by telephone. Each such notice must be
received by the Swing Line Lender and the Administrative Agent not later than
1:00 p.m. on the requested borrowing date, and shall specify (i) the amount to
be borrowed, which shall be a minimum of $100,000, and (ii) the requested
borrowing date, which shall be a Business Day. Each such telephonic notice must
be confirmed promptly by delivery to the Swing Line Lender and the
Administrative Agent of a written Swing Line Loan Notice, appropriately
completed and signed by a Responsible Officer of the applicable Borrower.
Promptly after receipt by the Swing Line Lender of any telephonic Swing Line
Loan Notice, the Swing Line Lender will confirm with the Administrative Agent
(by telephone or in writing) that the Administrative Agent has also received
such Swing Line Loan Notice and, if not, the Swing Line Lender will notify the
Administrative Agent (by telephone or in writing) of the contents thereof.
Unless the Swing Line Lender has received notice (by telephone or in writing)
from the Administrative Agent (including at the request of any Revolving Loan
Lender) prior to 2:00 p.m. on the date of the proposed Swing Line Borrowing (A)
directing the Swing Line Lender not to make such Swing Line Loan as a result of
the limitations set forth in the proviso to the first sentence of Section
2.04(a), or (B) that one or more of the applicable conditions specified in
Section 4.02 (it being agreed that no Swing Line Loans shall be borrowed on the
Closing Date) is not then satisfied, then, subject to the terms and conditions
hereof, the Swing Line Lender will, not later than 3:00 p.m. on the borrowing
date specified in such Swing Line Loan Notice, make the amount of its Swing Line
Loan available to the applicable Borrower at its office by crediting the account
of the applicable Borrower on the books of the Swing Line Lender or to such
other account as the applicable Borrower may designate in writing to the
Administrative Agent in immediately available funds.

      (c) Refinancing of Swing Line Loans.

            (i) The Swing Line Lender at any time in its sole and absolute
      discretion may request, on behalf of the Borrowers (which hereby
      irrevocably authorize the Swing Line Lender to so request on its behalf),
      that each Revolving Loan Lender make a Base Rate Revolving Loan in an
      amount equal to such Revolving Loan Lender's Pro Rata Share of the amount
      of Swing Line Loans then outstanding. Such request shall be made in
      writing (which written request shall be deemed to be a Committed Loan
      Notice for purposes hereof) and in accordance with the requirements of
      Section 2.02, without regard to the

                                      -51-
<PAGE>

      minimum and multiples specified therein for the principal amount of Base
      Rate Loans, but subject to the unutilized portion of the Aggregate
      Revolving Loan Commitments and the conditions set forth in Section 4.02.
      The Swing Line Lender shall furnish the applicable Borrower with a copy of
      the applicable Committed Loan Notice promptly after delivering such notice
      to the Administrative Agent. Each Revolving Loan Lender shall make an
      amount equal to its Pro Rata Share of the amount specified in such
      Committed Loan Notice available to the Administrative Agent in immediately
      available funds for the account of the Swing Line Lender at the
      Administrative Agent's Office not later than 1:00 p.m. on the day
      specified in such Committed Loan Notice, whereupon, subject to Section
      2.04(c)(ii), each Revolving Loan Lender that so makes funds available
      shall be deemed to have made a Base Rate Revolving Loan to the applicable
      Borrower in such amount. The Administrative Agent shall remit the funds so
      received to the Swing Line Lender.

            (ii) If for any reason any Swing Line Loan cannot be refinanced by
      such a Revolving Loan Borrowing in accordance with Section 2.04(c)(i), the
      request for Base Rate Revolving Loans submitted by the Swing Line Lender
      as set forth herein shall be deemed to be a request by the Swing Line
      Lender that each of the Revolving Loan Lenders fund its risk participation
      in the relevant Swing Line Loan and each Revolving Loan Lender's payment
      to the Administrative Agent for the account of the Swing Line Lender
      pursuant to Section 2.04(c)(i) shall be deemed payment in respect of such
      participation.

            (iii) If any Revolving Loan Lender fails to make available to the
      Administrative Agent for the account of the Swing Line Lender any amount
      required to be paid by such Revolving Loan Lender pursuant to the
      foregoing provisions of this Section 2.04(c) by the time specified in
      Section 2.04(c)(i), the Swing Line Lender shall be entitled to recover
      from such Revolving Loan Lender (acting through the Administrative Agent),
      on demand, such amount with interest thereon for the period from the date
      such payment is required to the date on which such payment is immediately
      available to the Swing Line Lender at a rate per annum equal to the
      greater of the Federal Funds Rate and a rate determined by the Swing Line
      Lender in accordance with banking industry rules on interbank
      compensation. A certificate of the Swing Line Lender submitted to any
      Revolving Loan Lender (through the Administrative Agent) with respect to
      any amounts owing under this clause (iii) shall be conclusive absent
      manifest error.

            (iv) Each Revolving Loan Lender's obligation to make Revolving Loans
      or to purchase and fund risk participations in Swing Line Loans pursuant
      to this Section 2.04(c) shall be absolute and unconditional and shall not
      be affected by any circumstance, including (A) any setoff, counterclaim,
      recoupment, defense or other right which such Revolving Loan Lender may
      have against the Swing Line Lender, the Borrowers or any other Person for
      any reason whatsoever, (B) the occurrence or continuance of a Default, or
      (C) any other occurrence, event or condition, whether or not similar to
      any of the foregoing; provided that each Revolving Loan Lender's
      obligation to make Revolving Loans pursuant to this Section 2.04(c) is
      subject to the conditions set forth in Section 4.02. No such funding of
      risk participations shall relieve or otherwise impair the obligation of
      the Borrowers to repay Swing Line Loans, together with interest as
      provided herein.

                                      -52-
<PAGE>

      (d) Repayment of Participations.

            (i) At any time after any Revolving Loan Lender has purchased and
      funded a risk participation in a Swing Line Loan, if the Swing Line Lender
      receives any payment on account of such Swing Line Loan, the Swing Line
      Lender will distribute to such Revolving Loan Lender its Pro Rata Share of
      such payment (appropriately adjusted, in the case of interest payments, to
      reflect the period of time during which such Revolving Loan Lender's risk
      participation was funded) in the same funds as those received by the Swing
      Line Lender.

            (ii) If any payment received by the Swing Line Lender in respect of
      principal or interest on any Swing Line Loan is required to be returned by
      the Swing Line Lender under any of the circumstances described in Section
      10.05 (including pursuant to any settlement entered into by the Swing Line
      Lender in its discretion), each Revolving Loan Lender shall pay to the
      Swing Line Lender its Pro Rata Share thereof on demand of the
      Administrative Agent, plus interest thereon from the date of such demand
      to the date such amount is returned, at a rate per annum equal to the
      Federal Funds Rate. The Administrative Agent will make such demand upon
      the request of the Swing Line Lender. The obligations of the Revolving
      Loan Lenders under this clause shall survive the payment in full of the
      Obligations and the termination of this Agreement.

      (e) Interest for Account of Swing Line Lender. The Swing Line Lender shall
be responsible for invoicing the Borrowers for interest on the Swing Line Loans.
Until each Revolving Loan Lender funds its Base Rate Revolving Loan or risk
participation pursuant to this Section 2.04 to refinance such Revolving Loan
Lender's Pro Rata Share of any Swing Line Loan, interest in respect of such Pro
Rata Share shall be solely for the account of the Swing Line Lender.

      (f) Payments Directly to Swing Line Lender. The Borrowers shall make all
payments of principal and interest in respect of the Swing Line Loans directly
to the Swing Line Lender.

      2.05 PREPAYMENTS.

      (a) Optional. (i) The Borrowers may, upon notice to the Administrative
Agent, at any time or from time to time voluntarily prepay Revolving Loans or
Term Loans, or both, in whole or in part without premium or penalty; provided
that (A) such notice must be received by the Administrative Agent not later than
(i) 1:00 p.m. three Business Days prior to any date of prepayment of Eurodollar
Rate Loans and (ii) 12:00 noon on the date of prepayment of Base Rate Loans; (B)
any prepayment of Eurodollar Rate Loans shall be in a principal amount of
$2,000,000 or a whole multiple of $500,000 in excess thereof; and (C) any
prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a
whole multiple of $100,000 in excess thereof or, in each case, if less, the
entire principal amount thereof then outstanding. Each such notice shall specify
the date and amount of such prepayment and the Type(s) of Loans to be prepaid.
The Administrative Agent will promptly notify each Revolving Loan Lender and
Term Lender, as applicable, of its receipt of each such notice, and of the
amount of such Lender's Pro Rata Share of such prepayment. If such notice is
given by the Borrowers, the Borrowers shall be

                                      -53-
<PAGE>

committed, jointly and severally, to make such prepayment and the payment amount
specified in such notice shall be due and payable on the date specified therein.
Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued
interest on the amount prepaid, together with any additional amounts required
pursuant to Section 3.05. Each such prepayment shall be applied among the
Facilities in such amounts and in accordance with their respective Pro Rata
Shares.

      (ii) The Borrowers may, upon notice to the Swing Line Lender (with a copy
to the Administrative Agent), at any time or from time to time, voluntarily
prepay Swing Line Loans in whole or in part without premium or penalty; provided
that (i) such notice must be received by the Swing Line Lender and the
Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and
(ii) any such prepayment shall be in a minimum principal amount of $50,000. Each
such notice shall specify the date and amount of such prepayment. If such notice
is given by the Borrowers, the Borrowers shall be committed, jointly and
severally, to make such prepayment and the payment amount specified in such
notice shall be due and payable on the date specified therein.

      (b) Revolving Loan Prepayments. If for any reason the Outstanding Amount
of the Revolving Loans at any time exceed the Aggregate Revolving Loan
Commitments then in effect, the Borrowers shall immediately prepay Revolving
Loans and/or Cash Collateralize the L/C Obligations in an aggregate amount equal
to such excess; provided that the Borrowers shall not be required to Cash
Collateralize the L/C Obligations pursuant to this Section 2.05(b) unless after
giving effect to the prepayment of any Revolving Loans the Outstanding Amount of
the Revolving Loans exceeds the Aggregate Revolving Loan Commitments then in
effect.

      therefrom and the aggregate of such Net Cash Proceeds of Asset Sales shall
      not exceed $15,000,000 in any fiscal year of Holdings, such proceeds shall
      not be required to be so applied on such date to the extent that Borrowers
      shall have delivered a certificate to the Administrative Agent on or prior
      to such fifth Business Day stating that such Net Cash Proceeds are

      has elected by notice to the Borrowers on or prior to such fifth Business
      Day to require such proceeds to be used, in each case, to repair, replace
      or restore any property (including putting any real property in a safe and
      secure condition) in respect of which such Net Cash Proceeds were paid or
      to reinvest in other fixed or capital assets or to acquire all of the

Cash Flow Period, the Borrowers shall make prepayments in accordance with
Sections 2.05(h) and (i) in an

                                      -55-
<PAGE>

aggregate amount equal to 50% of Excess Cash Flow for the Excess Cash Flow
Period then ended less any voluntary prepayments of Term Loans and any permanent
voluntary reductions to the Revolving Commitments to the extent that an equal
amount of the Revolving Loans simultaneously is repaid, in each case so long as
such amounts are not already reflected in Debt Service, during such Excess Cash
Flow Period; provided that, in the event the Total Leverage Ratio as of the last
day of such fiscal year is less than 3.00 to 1.00, the Borrowers shall only be
required to make such prepayments in an aggregate amount equal to 25% of Excess
Cash Flow for the Excess Cash Flow Period then ended less any voluntary
prepayments of Term Loans and any permanent voluntary reductions to the
Revolving Commitments to the extent that an equal amount of the Revolving Loans
simultaneously is repaid, in each case so long as such amounts are not already
reflected in Debt Service, during such Excess Cash Flow Period; provided,
further, that in the event the Total Leverage Ratio as of the last day of such
fiscal year is less than 2.00 to 1.00, the Borrowers shall not be required to
make any such prepayments pursuant to this Section 2.05(g).

      (h) Application of Prepayments. Prior to any optional or mandatory
prepayment hereunder, the Borrowers shall select the Borrowing or Borrowings to
be prepaid and shall specify such selection in the notice of such prepayment
pursuant to Section 2.05(i), subject to the provisions of this Section 2.05(h).
Any prepayments of Term Loans pursuant to Section 2.05(c), (d), (e), (f) or (g)
shall be applied to reduce scheduled prepayments required under Section 2.07 on
a pro rata basis among the prepayments remaining to be made on the Term Loans.
After application of mandatory prepayments of Term Loans described above in this
Section 2.05(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 the
Borrowers shall comply with Section 2.05(b).

      Amounts to be applied pursuant to this Section 2.05 to the prepayment of
Term 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 Rate
Term Loans or Eurodollar Rate Revolving Loans, as applicable. Notwithstanding
the foregoing, if the amount of any prepayment of Loans required under this
Section 2.05 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
immediately prepaid and, at the election of the Borrowers, the Excess Amount
shall be either (A) deposited in an escrow account on terms reasonably
satisfactory to the Collateral Agent 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 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 3.05.

                                      -56-

      (i) Notice of Prepayment. The Borrowers 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 1:00 p.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 12:00 noon, 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 1:00 p.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. Each voluntary 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. Each prepayment of a Borrowing shall be
applied ratably to the Loans included in the prepaid Borrowing and otherwise in
accordance with this Section 2.05. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.08.

      2.06 TERMINATION OR REDUCTION OF COMMITMENTS.

      (a) Revolving Loan Commitments. The Borrowers may, upon notice to the
Administrative Agent, terminate the Aggregate Revolving Loan Commitments, or
from time to time permanently reduce the Aggregate Revolving Loan Commitments;
provided that (i) any such notice shall be received by the Administrative Agent
not later than 1:00 p.m. two Business Days prior to the date of termination or
reduction, (ii) any such partial reduction shall be in an aggregate amount of
$5,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) the
Borrowers shall not terminate or reduce the Aggregate Revolving Loan Commitments
if, after giving effect thereto and to any concurrent prepayments hereunder, the
Outstanding Amount of Revolving Loans would exceed the Aggregate Revolving Loan
Commitments, and (iv) if, after giving effect to any reduction of the Aggregate
Revolving Loan Commitments, the Letter of Credit Sublimit or the Swing Line
Sublimit exceeds the amount of the Aggregate Revolving Loan Commitments, such
Sublimit shall be automatically reduced by the amount of such excess. The
Administrative Agent will promptly notify the Revolving Loan Lenders of any such
notice of termination or reduction of the Aggregate Revolving Loan Commitments.
Any reduction of the Aggregate Revolving Loan Commitments shall be applied to
the Commitment of each Revolving Loan Lender according to its Pro Rata Share.
All fees accrued until the effective date of any termination of the Aggregate
Revolving Loan Commitments shall be paid on the effective date of such
termination.

      (b) Term Loan Commitments. The Term Loan Commitments of each Term Loan
Lenders shall be automatically terminated on the Closing Date upon the Borrowing
of the Term Loans on such date.

      2.07 REPAYMENT OF LOANS.

quarter (or, in the case of the last such date on the last Business Day on or
prior to such date)):

      2.09 FEES. In addition to certain fees described in subsections (i) and
(j) of Section 2.03:

            (a) Commitment Fee. The Borrowers, jointly and severally, shall pay
      to the Administrative Agent for the account of each Revolving Lender in
      accordance with its Pro Rata Share, a commitment fee equal to 0.50% per
      annum times the actual daily amount by which the Aggregate Revolving Loan
      Commitments exceed the sum of (i) the Outstanding Amount of Revolving
      Loans and (ii) the Outstanding Amount of L/C Obligations. The commitment
      fee shall accrue at all times during the Availability Period, including at
      any time during which one or more of the conditions in Section 4.02 is not
      met, and shall be due and payable quarterly in arrears on the last
      Business Day of each February, May, August and November, commencing with
      May 31, 2005, and on the Revolving Loan Maturity Date.

            (b) Other Fees. The Borrowers shall pay to the Arranger and the
      Administrative Agent for their own respective accounts fees in the amounts
      and at the times specified in the Fee Letter. Such fees shall be fully
      earned when paid and shall not be refundable for any reason whatsoever.

      2.10 COMPUTATION OF INTEREST AND FEES. All computations of interest for
Base Rate Loans when the Base Rate is determined by Bank of America's "prime
rate" shall be made on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed. All other computations of fees and interest shall
be made on the basis of a 360-day year and actual days elapsed (which results in
more fees or interest, as applicable, being paid than if computed on the basis
of a 365-day year). Interest shall accrue on each Loan for the day on which the
Loan is made, continued or converted from a Loan of another Type, and shall not
accrue on a Loan, or any portion thereof, for the day on which the Loan or such
portion is paid or converted to a Loan of another Type, provided that any Loan
that is repaid on the same day on which it is made shall, subject to Section
2.12(a), bear interest for one day. Each determination by the Administrative
Agent of an interest rate or fee hereunder shall be conclusive and binding for
all purposes, absent manifest error.

      2.11 EVIDENCE OF DEBT.

      (a) The Credit Extensions made by each Lender shall be evidenced by one or
more accounts or records maintained by such Lender and by the Administrative
Agent in the ordinary course of business. The accounts or records maintained by
the Administrative Agent and each Lender shall be conclusive absent manifest
error of the amount of the Credit Extensions made by the Lenders to the
Borrowers and the interest and payments thereon. Any failure to so record or any
error in doing so shall not, however, limit or otherwise affect the obligation
of the Borrowers hereunder to pay any amount owing with respect to the
Obligations. In the event of any conflict between the accounts and records
maintained by any Lender and the accounts and records of the Administrative
Agent in respect of such matters, the accounts and records of the Administrative
Agent shall control in the absence of manifest error.

      (b) Upon the request of any Revolving Loan Lender made through the
Administrative Agent, the Borrowers shall execute and deliver to such Revolving
Loan Lender (through the

                                      -60-
<PAGE>

Administrative Agent) a Revolving Loan Note, which shall evidence such Revolving
Loan Lender's Revolving Loan Loans in addition to such accounts or records. Each
Revolving Loan Lender may attach schedules to a Revolving Loan Note and endorse
thereon the date, Type (if applicable), amount, currency and maturity of its
Revolving Loans and payments with respect thereto.

      (c) Upon the request of any Term Loan Lender made through the
Administrative Agent, the Borrowers shall execute and deliver to such Term Loan
Lender (through the Administrative Agent) a Term Loan Note, which shall evidence
such Term Loan Lender's Term Loan Loans in addition to such accounts or records.
Each Term Loan Lender may attach schedules to a Term Loan Note and endorse
thereon the date, Type (if applicable), amount, currency and maturity of its
Term Loans and payments with respect thereto.

      (d) Upon the request of the Swing Line Lender made through the
Administrative Agent, the Borrowers shall execute and deliver to the Swing Line
Lender (through the Administrative Agent) a Swing Line Loan Note, which shall
evidence the Swing Line Lender's Swing Line Loans in addition to such accounts
or records. The Swing Line Lender may attach schedules to the Swing Line Loan
Note and endorse thereon the date, Type (if applicable), amount, currency and
maturity of its Swing Line Loans and payments with respect thereto.

      (e) In addition to the accounts and records referred to in subsections
(a), (b) and (c) above in this Section 2.11, each Lender and the Administrative
Agent shall maintain in accordance with its usual practice accounts or records
evidencing the purchases and sales by such Lender of participations in Letters
of Credit and Swing Line Loans. In the event of any conflict between the
accounts and records maintained by the Administrative Agent and the accounts and
records of any Lender in respect of such matters, the accounts and records of
the Administrative Agent shall control in the absence of manifest error.

      2.12 PAYMENTS GENERALLY; ADMINISTRATIVE AGENT'S CLAWBACK.

      (a) General. All payments to be made by the Borrowers shall be made
without condition or deduction for any counterclaim, defense, recoupment or
setoff. Except as otherwise expressly provided herein, all payments by the
Borrowers hereunder shall be made to the Administrative Agent, for the account
of the respective Lenders to which such payment is owed, at the Administrative
Agent's Office in Dollars and in immediately available funds not later than 2:00

distribute to each Lender its Pro Rata Share (or other applicable share as
provided herein) of such payment in like funds as received by wire transfer to
such Lender's Lending Office. All payments received by the Administrative Agent
after 2:00 p.m. shall be deemed received on the next succeeding Business Day and
any applicable interest or fee shall continue to accrue. If any payment to be
made by the Borrowers shall come due on a day other than a Business Day, payment
shall be made on the next following Business Day, and such extension of time
shall be reflected in computing interest or fees, as the case may be.

      (b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless
the Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender's

                                      -61-
<PAGE>

Pro Rata Share of such Borrowing, the Administrative Agent may assume that such
Lender has made such share available on such date in accordance with Section
2.02 and may, in reliance upon such assumption, make available to the Borrowers
a corresponding amount. In such event, if a Lender has not in fact made its
share of the applicable Borrowing available to the Administrative Agent, then
the applicable Lender and the Borrowers severally agree to pay to the
Administrative Agent forthwith on demand such corresponding amount in
immediately available funds with interest thereon, for each day from and
including the date such amount is made available to the Borrowers to but
excluding the date of payment to the Administrative Agent, at (A) in the case of
a payment to be made by such Lender, the greater of the Federal Funds Rate and a
rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation and (B) in the case of a payment to be made by
the Borrowers, the interest rate applicable to Base Rate Loans. If the Borrowers
and such Lender shall pay such interest to the Administrative Agent for the same
or an overlapping period, the Administrative Agent shall promptly remit to the
Borrowers the amount of such interest paid by the Borrowers for such period. If
such Lender pays its share of the applicable Borrowing to the Administrative
Agent, then the amount so paid shall constitute such Lender's Revolving Loan or
Term Loan, as the case may be, included in such Borrowing. Any payment by the
Borrowers shall be without prejudice to any claim the Borrowers may have against
a Lender that shall have failed to make such payment to the Administrative
Agent.

      (ii) Payments by the Borrowers; Presumptions by Administrative Agent.
Unless the Administrative Agent shall have received notice from the Borrowers
prior to the date on which any payment is due to the Administrative Agent for
the account of the Lenders or the L/C Issuer hereunder that the Borrowers will
not make such payment, the Administrative Agent may assume that the Borrowers
have made such payment on such date in accordance herewith and may, in reliance
upon such assumption, distribute to the Lenders or the L/C Issuer, as the case
may be, the amount due. In such event, if the Borrowers have not in fact made
such payment, then each of the Lenders or the L/C Issuer, as the case may be,
severally agrees to repay to the Administrative Agent forthwith on demand the
amount so distributed to such Lender or the L/C Issuer, in immediately available
funds 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 Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation.

      A notice of the Administrative Agent to any Lender or the Borrowers with
respect to any amount owing under this subsection (b) shall be conclusive,
absent manifest error.

      (c) Failure to Satisfy Conditions Precedent. If any Lender makes available
to the Administrative Agent funds for any Loan to be made by such Lender as
provided in the foregoing provisions of this Article II, and such funds are not
made available to the Borrowers by the Administrative Agent because the
conditions to the applicable Credit Extension set forth in Article IV are not
satisfied or waived in accordance with the terms hereof, the Administrative
Agent shall promptly return such funds (in like funds as received from such
Lender) to such Lender, without interest.

      (d) Obligations of Lenders Several. The obligations of the Lenders
hereunder to make Revolving Loans or Term Loans, or both, as the case may be, to
fund participations in

                                      -62-
<PAGE>

Letters of Credit and Swing Line Loans and to make payments pursuant to Section
10.04(c) are several and not joint. The failure of any Lender to make any
Revolving Loan or Term Loan, to fund any such participation or to make any
payment under Section 10.04(c) on any date required hereunder shall not relieve
any other Lender of its corresponding obligation to do so on such date, and no
Lender shall be responsible for the failure of any other Lender to so make its
Revolving Loan or Term Loan, to purchase its participation or to make its
payment under Section 10.04(c).

      (e) Funding Source. Nothing herein shall be deemed to obligate any Lender
to obtain the funds for any Loan in any particular place or manner or to
constitute a representation by any Lender that it has obtained or will obtain
the funds for any Loan in any particular place or manner.

      2.13 SHARING OF PAYMENTS BY LENDERS. If any Lender shall, by exercising
any right of setoff or counterclaim or otherwise, obtain payment in respect of
any principal of or interest on any of the Term Loans and/or Revolving Loans
made by it, or the participations in L/C Obligations or in Swing Line Loans held
by it resulting in such Lender's receiving payment of a proportion of the
aggregate amount of such Loans or participations and accrued interest thereon
greater than its pro rata share thereof as provided herein, then the Lender
receiving such greater proportion shall (a) notify the Administrative Agent of
such fact, and (b) purchase (for cash at face value) participations in the Term
Loans and/or Revolving Loans and subparticipations in L/C Obligations and Swing
Line Loans of the other Lenders, or make such other adjustments as shall be
equitable, so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with their respective Pro Rata Share, provided
that:

            (i) if any such participations or subparticipations are purchased
      and all or any portion of the payment giving rise thereto is recovered,
      such participations or subparticipations shall be rescinded and the
      purchase price restored to the extent of such recovery, without interest;
      and

            (ii) the provisions of this Section shall not be construed to apply
      to (x) any payment made by the Borrowers pursuant to and in accordance
      with the express terms of this Agreement or (y) any payment obtained by a
      Lender as consideration for the assignment of or sale of a participation
      in any of its Revolving Loan or Term Loans or subparticipations in L/C
      Obligations or Swing Line Loans to any assignee or participant, other than
      to the Borrowers or any Subsidiary thereof (as to which the provisions of
      this Section shall apply).

      Each Loan Party consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law and Section 10.08, 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 to the same extent as if such Lender were a direct creditor of
such Loan Party in the amount of such participation.

                                      -63-

      2.14 INCREASE IN COMMITMENTS.

      (a) Request for Increase. Upon notice to the Administrative Agent (which
shall promptly notify the Lenders), the Borrowers may from time to time request
one or more new term loans in an amount (the "Additional Term Loans") (for all
such requests) not exceeding $100,000,000 in the aggregate, which Additional
Term Loans will be a new tranche of term loans under this Agreement; provided
that (i) no Event of Default or Default exists or would exist after giving
effect thereto, (ii) the Borrowers shall be in compliance with Section 7.11 on a
Pro Forma Basis after giving effect thereto, (iii) the Additional Term Loans
shall have a Weighted Average Life to Maturity equal to or greater than the
original Term Loans, (iv) the Applicable Rate with respect to any Additional
Term Loans shall not be more than 0.25% higher than the Applicable Rate with
respect to the existing tranche of Term Loans, (v) any such request for an
increase shall be in a minimum amount of $20,000,000 and (vi) the Borrowers may
make a maximum of three such requests. At the time of sending such notice, the
Borrowers shall specify the identity of each Eligible Assignee (and any existing
Lender) to whom the Borrowers propose any portion of such Additional Term Loans
be allocated and the amounts of such allocations; provided, however, that (A)
any existing Lender approached to provide all or a portion of the Additional
Term Loans may elect or decline, in its sole discretion, to provide all or any
portion of such Additional Term Loans offered to it and (B) any Eligible
Assignee that is not an existing Lender (a "New Additional Term Loan Lender")
shall be approved by the Administrative Agent and the Borrowers (such approvals
not to be unreasonably withheld or delayed) (each New Additional Term Loan
Lender or existing Lender, an "Additional Term Loan Lender").

      (b) Additional Term Loan Effective Date. The Additional Term Loans shall
be effected by a joinder agreement to this Agreement (the "Additional Term Loans
Joinder Agreement") executed by the Borrowers, the Administrative Agent and each
Additional Term Loan Lender making or providing such Additional Term Loans, in
form and substance reasonably satisfactory to each of them, subject, however, to
the satisfaction of the conditions precedent set forth in this Section 2.14. The
Additional Term Loan Joinder Agreement shall, without the consent of any other
Lenders, effect such amendments to this Agreement and the other Loan Documents.
If the Additional Term Loans are provided in accordance with this Section 2.14,
the Administrative Agent and the Borrowers shall determine the effective date
(each, an "Additional Term Loan Effective Date") and the final allocation of
such Additional Term Loans.

      (c) Conditions to Effectiveness of Increase. As a condition precedent to
such increase, the Borrowers shall deliver to the Administrative Agent a
certificate of each Loan Party dated as of the Additional Term Loan Effective
Date (in sufficient copies for each Lender) signed by a Responsible Officer of
such Loan Party (i) certifying and attaching the resolutions adopted by such
Loan Party approving or consenting to such increase and (ii) in the case of the
Borrowers, certifying that, before and after giving effect to such increase, (A)
the representations and warranties contained in Article V and the other Loan
Documents are true and correct in all material respects on and as of the
Additional Term Loan Effective Date, except to the extent that such
representations and warranties specifically refer to an earlier date, in which
case they are true and correct in all material respects as of such earlier date,
and except that for purposes of this Section 2.14, the representations and
warranties contained in subsections (a) and (b) of Section 5.05 shall be deemed
to refer to the most recent statements furnished pursuant to clauses (a) and
(b), respectively, of Section 6.01, and (B) no Event of Default or Default
exists.

                                      -64-
<PAGE>

      (d) Conflicting Provisions. This Section 2.14 shall supersede any
provisions in Sections 2.13 or 10.01 to the contrary.

      2.15 JOINT AND SEVERAL LIABILITY. The Borrowers shall have joint and
several liability in respect of all Obligations hereunder and under any other
Loan Document to which any Borrower is a party, without regard to any defense
(other than the defense that payment in full has been made), setoff or
counterclaim which may at any time be available to or be asserted by any other
Loan Party against the Lenders, or by any other circumstance whatsoever (with or
without notice to or knowledge of the Borrowers) which constitutes, or might be
construed to constitute, an equitable or legal discharge of the Borrowers'
liability hereunder, in bankruptcy or in any other instance, and the Obligations
of the Borrowers hereunder shall not be conditioned or contingent upon the
pursuit by the Lenders or any other person at any time of any right or remedy
against the Borrowers or against any other person which may be or become liable
in respect of all or any part of the Obligations or against any Collateral or
Guarantee therefor or right of offset with respect thereto. The Borrowers hereby
acknowledge that this Agreement is the independent and several obligation of
each Borrower (regardless of which Borrower shall have delivered a Notice of
Borrowing) and may be enforced against each Borrower separately, whether or not
enforcement of any right or remedy hereunder has been sought against any other
Borrower. Each Borrower hereby expressly waives, with respect to any of the
Loans made to any other Borrower hereunder and any of the amounts owing
hereunder by such other Loan Parties in respect of such Loans, diligence,
presentment, demand of payment, protest and all notices whatsoever, and any
requirement that the Administrative Agent or any Lender exhaust any right, power
or remedy or proceed against such other Loan Parties under this Agreement or any
other agreement or instrument referred to herein or against any other person
under any other guarantee of, or security for, any of such amounts owing
hereunder.

                                  ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

      3.01 TAXES.

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

      (b) Payment of Other Taxes by the Borrowers. Without limiting the
provisions of subsection (a) above, the Borrowers shall timely pay any Other
Taxes to the relevant Governmental Authority in accordance with applicable law.

                                      -65-
<PAGE>

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

      (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Borrowers to a Governmental Authority,
the Borrowers 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) Status of Lenders. Any Foreign Lender that is entitled to an exemption
from or reduction of withholding tax under the law of the jurisdiction that
imposes the obligation to withhold such tax or under any treaty to which such
jurisdiction is a party, with respect to payments hereunder or under any other
Loan Document shall, to the extent it may lawfully do so, deliver to the
Borrowers (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law or reasonably requested by the Borrowers or the
Administrative Agent, such properly completed and executed documentation
prescribed by applicable law as will permit such payments to be made without
withholding or at a reduced rate of withholding. In addition, any Lender, if
requested by the Borrowers or the Administrative Agent, shall deliver such other
documentation prescribed by applicable law or reasonably requested by the
Borrowers or the Administrative Agent as will enable the Borrowers or the
Administrative Agent to determine whether or not such Lender is subject to
backup withholding or information reporting requirements.

      Without limiting the generality of the foregoing, in the event that either
Borrower is resident for tax purposes in the United States, any Foreign Lender
shall, to the extent it may lawfully do so, deliver to the Borrowers and the
Administrative Agent (in such number of copies as shall be requested by the
recipient) on or prior to the date on which such Foreign Lender becomes a Lender
under this Agreement (and from time to time thereafter upon the request of the
Borrowers or the Administrative Agent, but only if such Foreign Lender is
legally entitled to do so), whichever of the following is applicable:

            (i) duly completed copies of Internal Revenue Service Form W-8BEN
      claiming eligibility for benefits of an income tax treaty to which the
      United States is a party,

            (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

            (iii) in the case of a Foreign Lender claiming the benefits of the
      exemption for portfolio interest under section 881(c) of the Code, (x) a
      certificate to the effect that such

                                      -66-
<PAGE>

      Foreign Lender is not (A) a "bank" within the meaning of section
      881(c)(3)(A) of the Code, (B) a "10 percent shareholder" of either
      Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a
      "controlled foreign corporation" described in section 881(c)(3)(C) of the
      Code and (y) duly completed copies of Internal Revenue Service Form
      W-8BEN, or

            (iv) any other form prescribed by applicable law as a basis for
      claiming exemption from or a reduction in United States Federal
      withholding tax duly completed together with such supplementary
      documentation as may be prescribed by applicable law to permit the
      Borrowers to determine the withholding or deduction required to be made.

      (f) Treatment of Certain Refunds. If the Administrative Agent, any Lender
or the L/C Issuer determines, in its sole discretion, that it has received a
refund of any Taxes or Other Taxes as to which it has been indemnified by the
Borrowers or with respect to which the Borrowers have paid additional amounts
pursuant to this Section, it shall pay to the Borrowers an amount equal to such
refund (but only to the extent of indemnity payments made, or additional amounts
paid, by the Borrowers under this Section with respect to the Taxes or Other
Taxes giving rise to such refund), net of all out-of-pocket expenses of the
Administrative Agent, such Lender or the L/C Issuer, as the case may be, and
without interest (other than any interest paid by the relevant Governmental
Authority with respect to such refund), provided that the Borrowers upon the
request of the Administrative Agent, such Lender or the L/C Issuer, agree to
repay the amount paid over to the Borrowers (plus any penalties, interest or
other charges imposed by the relevant Governmental Authority) to the
Administrative Agent, such Lender or the L/C Issuer in the event the
Administrative Agent, such Lender or the L/C Issuer is required to repay such
refund to such Governmental Authority. This subsection shall not be construed to
require the Administrative Agent, any Lender or the L/C Issuer to make available
its tax returns (or any other information relating to its taxes that it deems
confidential) to the Borrowers or any other Person. Notwithstanding anything to
the contrary, in no event will any Lender be required to pay any amount to the
Borrowers 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.

      3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans, or to determine or charge interest rates based upon the
Eurodollar Rate, or any Governmental Authority has imposed material restrictions
on the authority of such Lender to purchase or sell, or to take deposits of,
Dollars in the London interbank market, then, on notice thereof by such Lender
to the Borrowers through the Administrative Agent, any obligation of such Lender
to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to
Eurodollar Rate Loans shall be suspended until such Lender notifies the
Administrative Agent and the Borrowers that the circumstances giving rise to
such determination no longer exist. Upon receipt of such notice, the Borrowers
shall, upon demand from such Lender (with a copy to the Administrative Agent),
prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to
Base Rate Loans, either on the last day of the Interest Period therefor, if such
Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day,
or immediately, if such Lender may not lawfully continue to maintain such

                                      -67-
<PAGE>

Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrowers
shall also pay accrued interest on the amount so prepaid or converted.

      3.03 INABILITY TO DETERMINE RATES.

      (a) Eurodollar Rate Term Loans. If the Required Term Loan Lenders
determine that for any reason in connection with any request for a Eurodollar
Rate Term Loan or a conversion to or continuation thereof that (i) Dollar
deposits are not being offered to banks in the London interbank eurodollar
market for the applicable amount and Interest Period of such Eurodollar Rate
Term Loan, (ii) adequate and reasonable means do not exist for determining the
Eurodollar Rate for any requested Interest Period with respect to a proposed
Eurodollar Rate Term Loan, or (iii) the Eurodollar Rate for any requested
Interest Period with respect to a proposed Eurodollar Rate Term Loan does not
adequately and fairly reflect the cost to such Lenders of funding such
Eurodollar Rate Term Loan, the Administrative Agent will promptly so notify the
Borrowers and each Term Loan Lender. Thereafter, the obligation of the Term Loan
Lenders to make or maintain Eurodollar Rate Term Loans shall be suspended until
the Administrative Agent (upon the instruction of the Required Term Loan
Lenders) revokes such notice (which the Required Term Loan Lenders agree to do
promptly once such condition no longer exists). Upon receipt of such notice, the
Borrowers may revoke any pending request for a Term Loan Borrowing of,
conversion to or continuation of Eurodollar Rate Term Loans or, failing that,
will be deemed to have converted such request into a request for a Term Loan
Borrowing of Base Rate Loans in the amount specified therein.

      (b) Eurodollar Rate Revolving Loans. If the Required Revolving Loan
Lenders determine that for any reason in connection with any request for a
Eurodollar Rate Revolving Loan or a conversion to or continuation thereof that
(i) Dollar deposits are not being offered to banks in the London interbank
eurodollar market for the applicable amount and Interest Period of such
Eurodollar Rate Loan, (ii) adequate and reasonable means do not exist for
determining the Eurocurrency Rate for any requested Interest Period with respect
to a proposed Eurodollar Rate Revolving Loan, or (iii) the Eurodollar Rate for
any requested Interest Period with respect to a proposed Eurodollar Rate
Revolving Loan does not adequately and fairly reflect the cost to such Lenders
of funding such Eurodollar Rate Revolving Loan, the Administrative Agent will
promptly so notify the Borrowers and each Revolving Loan Lender. Thereafter, the
obligation of the Revolving Loan Lenders to make or maintain Eurodollar Rate
Revolving Loans shall be suspended until the Administrative Agent (upon the
instruction of the Required Revolving Loan Lenders) revokes such notice (which
the Required Revolving Loan Lenders agree to do promptly once such condition no
longer exists). Upon receipt of such notice, the Borrowers may revoke any
pending request for a Revolving Loan Borrowing of, conversion to or continuation
of Eurodollar Rate Revolving Loans or, failing that, will be deemed to have
converted such request into a request for a Revolving Loan Borrowing of Base
Rate Loans in the amount specified therein.

      3.04 INCREASED COSTS; RESERVES ON EURODOLLAR RATE LOANS.

      (a) Increased Costs Generally. If any Change in Law shall:

            (i) impose, modify or deem applicable any reserve, special deposit,
      compulsory loan, insurance charge or similar requirement against assets
      of, deposits with or for

                                      -68-
<PAGE>

      the account of, or credit extended or participated in by, any Lender
      (except any reserve requirement contemplated by Section 3.04(e)) or the
      L/C Issuer;

            (ii) subject any Lender or the L/C Issuer to any tax of any kind
      whatsoever with respect to this Agreement, any Letter of Credit, any
      participation in a Letter of Credit or any Eurodollar Rate Loan made by
      it, or change the basis of taxation of payments to such Lender or the L/C
      Issuer in respect thereof (except for Indemnified Taxes or Other Taxes
      covered by Section 3.01 and the imposition of, or any change in the rate
      of, any Excluded Tax payable by such Lender or the L/C Issuer); or

            (iii) impose on any Lender or the L/C Issuer or the London interbank
      market any other condition, cost or expense affecting this Agreement or
      Eurodollar Rate 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 Rate Loan (or of maintaining its
obligation to make any such Loan), or to increase the cost to such Lender or the
L/C Issuer of participating in, issuing or maintaining any Letter of Credit (or
of maintaining its obligation to participate in or to issue any Letter of
Credit), or to reduce the amount of any sum received or receivable by such
Lender or the L/C Issuer hereunder (whether of principal, interest or any other
amount) then, upon request of such Lender or the L/C Issuer, the Borrowers will
pay to such Lender or the L/C Issuer, as the case may be, such additional amount
or amounts as will compensate such Lender or the L/C Issuer, as the case may be,
for such additional costs incurred or reduction suffered.

      (b) Capital Requirements. If any Lender or the L/C Issuer determines that
any Change in Law affecting such Lender or the L/C Issuer or such Lender's or
the L/C Issuer's holding company, if any, regarding capital requirements has or
would have the effect of reducing the rate of return on such Lender's or the L/C
Issuer's capital or on the capital of such Lender's or the L/C Issuer's holding
company, if any, as a consequence of this Agreement, the Commitments of such
Lender or the Loans made by, or participations in Letters of Credit held by,
such Lender, or the Letters of Credit issued by the L/C Issuer, to a level below
that which such Lender or the L/C Issuer or such Lender's or the L/C Issuer's
holding company could have achieved but for such Change in Law (taking into
consideration such Lender's or the L/C Issuer's policies and the policies of
such Lender's or the L/C Issuer's holding company with respect to capital
adequacy), then from time to time the Borrowers will pay to such Lender or the
L/C Issuer, as the case may be, such additional amount or amounts as will
compensate such Lender or the L/C Issuer or such Lender's or the L/C Issuer's
holding company for any such reduction suffered.

      (c) Certificates for Reimbursement. A certificate of a Lender or the L/C
Issuer setting forth in reasonable detail the basis for calculating the amount
or amounts necessary to compensate such Lender or the L/C Issuer or its holding
company, as the case may be, as specified in subsection (a) or (b) of this
Section and delivered to the Borrowers shall be conclusive absent manifest
error. The Borrowers shall pay such Lender or the L/C Issuer, as the case may
be, the amount shown as due on any such certificate within 10 days after receipt
thereof.

      (d) Delay in Requests. Failure or delay on the part of any Lender or the
L/C Issuer to demand compensation pursuant to the foregoing provisions of this
Section shall not constitute a

                                      -69-
<PAGE>

waiver of such Lender's or the L/C Issuer's right to demand such compensation,
provided that the Borrowers shall not be required to compensate a Lender or the
L/C Issuer pursuant to the foregoing provisions of this Section for any
increased costs incurred or reductions suffered more than six months prior to
the date that such Lender or the L/C Issuer, as the case may be, notifies the
Borrowers of the Change in Law giving rise to such increased costs or reductions
and of such Lender's or the L/C Issuer's intention to claim compensation
therefor (except that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the six-month period referred to above shall
be extended to include the period of retroactive effect thereof).

      (e) Reserves on Eurodollar Rate Loans. The Borrowers shall pay to each
Lender, as long as such Lender shall be required to maintain reserves with
respect to liabilities or assets consisting of or including Eurocurrency funds
or deposits (currently known as "Eurocurrency liabilities"), additional interest
on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual
costs of such reserves allocated to such Loan by such Lender (as determined by
such Lender in good faith, which determination shall be conclusive), which shall
be due and payable on each date on which interest is payable on such Loan,
provided the Borrowers shall have received at least 10 days' prior notice (with
a copy to the Administrative Agent) of such additional interest from such
Lender. If a Lender fails to give notice 10 days prior to the relevant Interest
Payment Date, such additional interest shall be due and payable 10 days from
receipt of such notice.

      3.05 COMPENSATION FOR LOSSES. Upon written demand of any Lender (with a
copy to the Administrative Agent) from time to time, the Borrowers shall
promptly compensate such Lender for and hold such Lender harmless from any loss,
cost or reasonable out-of-pocket expense incurred by it as a result of:

            (a) any continuation, conversion, payment or prepayment of any Loan
      other than a Base Rate Loan on a day other than the last day of the
      Interest Period for such Loan (whether voluntary, mandatory, automatic, by
      reason of acceleration, or otherwise);

            (b) any failure by the Borrowers (for a reason other than the
      failure of such Lender to make a Loan) to prepay, borrow, continue or
      convert any Loan other than a Base Rate Loan on the date or in the amount
      notified by the Borrowers; or

            (c) any assignment of a Eurodollar Rate Loan on a day other than the
      last day of the Interest Period therefor as a result of a request by the
      Borrowers pursuant to Section 10.13;

including any loss or expense arising from the liquidation or reemployment of
funds (but excluding loss of anticipated profits) obtained by it to maintain
such Loan or from fees payable to terminate the deposits from which such funds
were obtained. The Borrowers shall also pay any customary administrative fees
charged by such Lender in connection with the foregoing.

      For purposes of calculating amounts payable by the Borrowers to the
Lenders under this Section 3.05, each Lender shall be deemed to have funded each
Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a
matching deposit or other borrowing in the London

interbank eurodollar market for a comparable amount and for a comparable period,
whether or not such Eurodollar Rate Loan was in fact so funded.

      3.06 MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.

      (a) Designation of a Different Lending Office. If any Lender requests
compensation under Section 3.04, or the Borrowers are required to pay any
additional amount to any Lender or any Governmental Authority for the account of
any Lender pursuant to Section 3.01, or if any Lender gives a notice pursuant to
Section 3.02, then such Lender shall use reasonable efforts to designate a
different Lending Office for funding or booking its Loans hereunder or to assign
its rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Lender, such designation or assignment
(i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04,
as the case may be, in the future, or eliminate the need for the notice pursuant
to Section 3.02, as applicable, and (ii) in each case, would not subject such
Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrowers hereby agree to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment.

      (b) Replacement of Lenders. If any Lender requests compensation under
Section 3.04, or if the Borrowers are required to pay any additional amount to
any Lender or any Governmental Authority for the account of any Lender pursuant
to Section 3.01, the Borrowers may replace such Lender in accordance with
Section 10.13.

      3.07 SURVIVAL. All of the Borrowers' obligations under this Article III
shall survive termination of the Aggregate Commitments and repayment of all
other Obligations hereunder.

the Collateral Agent, on behalf of the Secured Parties, as additional insured,
in form and substance reasonably satisfactory to the Administrative Agent.

to each Lender, fairly present in all material respects the consolidated pro
forma financial condition of Holdings and its Subsidiaries as at such date and
the consolidated pro forma results of operations of the Holdings and its
Subsidiaries for the period ended on such date. Such pro forma financial
statements have been prepared in good faith by the Borrowers, based on the
assumptions stated therein (which assumptions are believed by the Borrowers on
the Closing Date to be reasonable), and are based on the best information
available to the Borrowers as of the date of delivery thereof.

      (e) The consolidated forecasted balance sheet and statements of income and
cash flows of the Holdings and its Subsidiaries delivered pursuant to Section
6.01(c) were prepared in good faith on the basis of the assumptions stated
therein, which assumptions were fair in light of the conditions existing at the
time of delivery of such forecasts, and represented, at the time of delivery,
Holdings' best estimate of its future financial performance it being understood
that forecasts are subject to uncertainties and contingencies and that no
representation or warranty is given that any forecast will be realized.

      5.06 LITIGATION. There are no actions, suits, proceedings, claims or
disputes pending or, to the knowledge of Holdings and its Subsidiaries after due
and diligent investigation, threatened or contemplated, at law, in equity, in
arbitration or before any Governmental Authority, by or against Holdings or any
of its Subsidiaries or against any of their properties or revenues that (a)
purport to challenge or limit, directly or indirectly, the enforceability of
this Agreement or any other Loan Document, or any of the transactions
contemplated hereby or (b) except as set forth on Schedule 5.06, either
individually or in the aggregate, could reasonably be expected to have a

on Schedule 5.06.

      5.07 NO DEFAULT. Neither Holdings nor any of its Subsidiaries is in

the consummation of the transactions contemplated by this Agreement or any other
Loan Document.

      5.08 PROPERTIES.

      (a) Generally. Holdings and each of its Subsidiaries has good title to, or
valid leasehold interests in, all its property, except as would not reasonably
be expected to have a Material Adverse Effect, and all of such property is free
and clear of all Liens except for Permitted Liens and minor irregularities or
deficiencies in title that, individually or in the aggregate, do not materially
interfere with its ability to conduct its business as currently conducted or to
utilize such property for its intended purpose. The property of Holdings and its
Subsidiaries, taken as a whole, (i) is in good operating order, condition and
repair (ordinary wear and tear excepted), except to the extent 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 Holdings and its Subsidiaries as presently

                                      -80-
<PAGE>

      (b) Real Property. As of the Closing Date, Schedules 8(a) and 8(b) to the
Perfection Certificate dated the Closing Date contain a true and complete list
of each interest in Real Property (i) owned by any Holdings and its Subsidiaries
as of the date hereof and describes the type of interest therein held by such
Holdings and its Subsidiaries and whether such owned Real Property is leased by
Holdings or one of its Subsidiaries to a third party, and if so leased, whether
the underlying Lease contains any option to purchase all or any portion of such
Real Property or any interest therein or contains any right of first refusal
relating to any sale of such Real Property or any portion thereof or interest
therein and (ii) leased, subleased or otherwise occupied or utilized by Holdings
or its Subsidiaries, as lessee, sublessee, franchisee or licensee, as of the
date hereof where, in the case of this clause (ii) the fair market value of
assets located at such property exceeds $100,000.

      (c) No Casualty Event. None of Holdings or its Subsidiaries has received
any notice of, nor has any knowledge of, the occurrence or pendency or
contemplation of any Casualty Event affecting any material 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 6.07.

      (d) Collateral. Each Loan Party owns or has rights to use (i) all of the
Collateral and (ii) all rights with respect to any of the foregoing used in,
necessary for or material to each such company's business as currently
conducted, except as could not reasonably be expected to have a Material Adverse
Effect. The use by each of Holdings and its Subsidiaries 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 such 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.

            (iv) There is no Environmental Claim pending or, to the knowledge of
      Holdings and its Subsidiaries, threatened against Holdings and its
      Subsidiaries, or relating to the Real Property currently or formerly

      the operations of Holdings and its Subsidiaries, and there are no actions,
      activities, circumstances, conditions, events or incidents that could
      reasonably be expected to form the basis of such an Environmental Claim;
      and

            (v) No person with an indemnity or contribution obligation to
      Holdings and its Subsidiaries relating to compliance with or liability
      under Environmental Law is in default with respect to such obligation.

      (b) Except as set forth in Schedule 5.09:

            (i) None of Holdings or its Subsidiaries is obligated to perform any
      action or otherwise incur 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 such company is conducting or
      financing any Response pursuant to any Environmental Law with respect to
      any Real Property or any other location;

            (ii) No Real Property or facility owned, operated or leased by
      Holdings and its Subsidiaries and, to the knowledge of the Holdings and

      the consummation of the transactions contemplated hereby will not require

      investigation, remediation or cleanup pursuant to any Governmental Real
      Property Disclosure Requirements or any other Environmental Law; and

            (v) Holdings and its Subsidiaries have made available to the Lenders
      all material records and files in the possession, custody or control of,
      or otherwise reasonably available to, Holdings and its Subsidiaries
      concerning compliance with or liability under Environmental Law, including
      those concerning the existence of Hazardous Material at

                                      -82-
<PAGE>

      Real Property or facilities currently or formerly owned, operated, leased
      or used by Holdings and its Subsidiaries.

      5.10 INSURANCE. Schedule 5.10 sets forth a true, complete and correct
description of all insurance maintained by each Holdings and its Subsidiaries as
of the Closing Date. All insurance maintained by the Holdings and its
Subsidiaries is in full force and effect, all premiums have been duly paid and
none of Holdings or its Subsidiaries has received notice of violation or
cancellation thereof, except, in each case, where the failure to do so could not
reasonably be expected to have a Material Adverse Effect. 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, in each case to the extent same could not reasonably be expected to
have a Material Adverse Effect. Each of Holdings and its Subsidiaries has
insurance in such amounts and covering such risks and liabilities as are
customary for companies of a similar size engaged in similar businesses in
similar locations and as otherwise required by Section 6.07.

      5.11 TAXES. Holdings and its Subsidiaries have filed all Federal, state
and other material tax returns and reports required to be filed, and have paid
all Federal, state and other material taxes, assessments, fees and other
governmental charges levied or imposed upon them or their properties, income or
assets otherwise due and payable, except those that are being contested in good
faith by appropriate proceedings diligently conducted and for which adequate
reserves have been provided in accordance with GAAP. There is no proposed tax
assessment against Holdings or any Subsidiary that would, if made, have a
Material Adverse Effect. Neither any Loan Party nor any Subsidiary thereof is
party to any tax sharing agreement.

      5.12 ERISA COMPLIANCE. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. Each Borrower and ERISA Affiliate is in
compliance in all material respects with the presently applicable provisions of
ERISA and the Code with respect to each Employee Benefit Plan. The present value
of all accumulated benefit obligations of all underfunded Pension 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 the fair market value of the assets
of all such underfunded Pension Plans in an amount that could reasonably be
expected to have a Material Adverse Effect if the Plans were terminated. The
aggregate liabilities of the Borrowers and their 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, would not
reasonably be expected to result in a Material Adverse Effect. The Borrowers and
any Subsidiaries do not maintain or contribute to any plan, program, policy,
arrangement or agreement with respect to employees (or former employees)
employed outside the United States.

      5.13 SUBSIDIARIES; EQUITY INTERESTS. As of the Closing Date, Holdings does
not have any Subsidiaries other than those specifically disclosed in Part (a) of
Schedule 5.13, and all of the outstanding Equity Interests in such Subsidiaries
have been validly issued, are fully paid and nonassessable and are owned by a
Loan Party in the amounts specified on Part (a) of Schedule 5.13 free and clear
of all Liens except Permitted Liens. Holdings does not have any equity

                                      -83-
<PAGE>

investments in any other corporation or entity other than those specifically
disclosed in Part(b) of Schedule 5.13. All of the outstanding Equity Interests
in Holdings has been validly issued and are fully paid and nonassessable no
subsidiary of Holdings is party to any Contractual Obligation that, if entered
into after the Closing Date, would be prohibited by Section 7.09.

      5.14 MARGIN REGULATIONS; INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING
COMPANY ACT.

      (a) Neither Holdings nor any of its Subsidiaries is engaged or will
engage, principally or as one of its important activities, in the business of
purchasing or carrying margin stock, or extending credit for the purpose of
purchasing or carrying margin stock (within the meaning of Regulation U issued
by the FRB). Following the application of the proceeds of each Borrowing or
drawing under each Letter of Credit, not more than 25% of the value of the
assets (either of Holdings only or of Holdings and its Subsidiaries on a
consolidated basis) subject to the provisions of Section 7.01 or Section 7.05 or
subject to any restriction contained in any agreement or instrument between
Holdings or any of its Subsidiaries and any Lender or any Affiliate of any
Lender relating to Indebtedness and within the scope of Section 8.01(e) will be
margin stock.

      (b) None of Holdings, any Person Controlling Holdings, or any Subsidiary
(i) is a "holding company," or a "subsidiary company" of a "holding company," or
an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding
company," within the meaning of the Public Utility Holding Company Act of 1935,
or (ii) is or is required to be registered as an "investment company" under the
Investment Company Act of 1940.

      5.15 DISCLOSURE. No report, financial statement, certificate or other
information, including the Confidential Information Memorandum and the
Perfection Certificate, in each case concerning any Loan Party, furnished
(whether in writing or orally) by or on behalf of any Loan Party to any Agent or
any Lender in connection with the transactions contemplated hereby and the
negotiation of this Agreement or delivered hereunder or under any other Loan
Document (in each case, as modified or supplemented by other information so
furnished) contains any material misstatement of fact or omits to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading; provided
that, with respect to projected and pro forma financial information, the Loan
Parties represent only that such information was prepared in good faith based
upon assumptions believed to be reasonable at the time (it being understood that
projections and forecasts are subject to uncertainties and contingencies and no
assurance can be given that such projections or forecasts will be realized).

      5.16 COMPLIANCE WITH LAWS. Holdings and each of its Subsidiary is in
compliance in all material respects with the requirements of all Laws and all
orders, writs, injunctions and decrees applicable to it or to its properties,
except in such instances in which (a) such requirement of Law or order, writ,
injunction or decree is being contested in good faith by appropriate proceedings
diligently conducted or (b) the failure to comply therewith, either individually
or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect.

      5.17 SOLVENCY. On the Closing Date immediately following the consummation
of the Transactions and immediately following the making of each Loan and after
giving effect to the

                                      -84-
<PAGE>

application of the proceeds of each Loan on the date hereof, (a) the fair value
of the assets of each Loan Party (individually and on a consolidated basis with
its Subsidiaries which for this purpose shall include rights of contribution in
respect of obligations for which such Loan Party has provided a guarantee)
exceeds 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) which for this purpose shall
include rights of contribution in respect of obligations for which such loan
party has provided a guarantee is greater than the amount that will be required
to pay the probably liability of its debts and other liabilities, subordinated,
contingent or otherwise, as such debts and other liabilities become absolute and
matured (the valuation of contingent obligations being computed in light of all
the facts and circumstances existing on the date hereof that can reasonably be
expected to become an actual or matured liability); (c) each Loan Party
(individually and on a consolidated basis with its Subsidiaries) is able to pay
its debts and liabilities, subordinated, contingent or otherwise (the valuation
of contingent obligations being computed in light of all facts and circumstances
existing on the date hereof that can reasonably be expected to become an actual
or material liability), as such debts and liabilities become absolute and
matured; and (d) each Loan Party (individually and on a consolidated basis with
its Subsidiaries) does not have unreasonably small capital with which to conduct
the business in which it is engaged as such business is now conducted and is
proposed to be conducted following the Closing Date.

      (b) Copyright Office Filing. When the Security Agreement or the Copyright

States Copyright Office, the Liens created by such Security Agreement shall
constitute fully perfected Liens on, and security interests in, all right, title

each case subject to no Liens other than Permitted Liens.

      (c) Mortgages. Each Mortgage is effective to create, in favor of the
Collateral Agent, for its benefit and the benefit of the Secured Parties, legal,
valid and enforceable first priority Liens on, and security interests in, all of
the Loan Parties' right, title and interest in and to the Mortgaged Properties
thereunder and the proceeds thereof, subject only to Permitted Liens or

of the Lenders may be "public-side" Lenders (i.e., Lenders that do not wish to
receive material non-public information with respect to the Borrowers or their
securities) (each, a "public lender"). The Borrowers hereby agree that (w) all
Borrower Materials that are to be made available to Public Lenders shall be
clearly and conspicuously marked "PUBLIC" which, at a minimum, shall mean that

marking Borrower Materials "PUBLIC," the Borrowers shall be deemed to have
authorized the Administrative Agent, the Arrangers, the L/C Issuer and the

proprietary) with respect to the Borrowers or their securities for purposes of
United States Federal and state securities laws; (y) all Borrower Materials
marked "PUBLIC" are

                                      -91-

suitable only for posting on a portion of the Platform not designated "Public
Investor."

thereafter notify each Lender):

renewals, additions, improvements and replacements thereto necessary in order
that the business carried on in connection therewith may be properly conducted
at all times, except in the case of clause (a), (b), (c) or (d) where the

such risks as is customary with companies in the same or similar businesses
operating in the same or similar locations, including insurance with respect to

Administrative Agent may from time to time reasonably require (such policies to

satisfactory to the Administrative Agent and the Collateral Agent).

      (b) Additional Insurance. In addition to, and without limiting the
foregoing, Holdings and its Subsidiaries shall maintain or require the
maintenance of medical malpractice and other professional insurance with a
responsible insurance company (which may include any Insurance Subsidiary) for
and covering each Loan Party and each Loan Party's employees, officers,

                                      -93-

insurance) or additional insured on behalf of the Secured Parties (in the case
of liability insurance) or additional loss payee (in the case of property
insurance), as applicable.

Agent immediately whenever any separate insurance concurrent in form or
contributing in the event of loss with that required to be maintained under this
Section 6.07 is taken out by any Loan Party; and promptly deliver to the
Administrative Agent and the Collateral Agent a duplicate original copy of such
policy or policies.

      (e) Flood Insurance. With respect to each Mortgaged Property, obtain flood
insurance in such total amount as the Administrative Agent or the Required
Lenders may from time to time reasonably require, if at any time the area in
which any improvements located on any Mortgaged Property is designated a "flood
hazard area" in any Flood Insurance Rate Map published by the Federal Emergency
Management Agency (or any successor agency), and otherwise comply with the
National Flood Insurance Program as set forth in the Flood Disaster Protection
Act of 1973, as amended from time to time.

      (f) Broker's Report. Deliver to the Administrative Agent and the
Collateral Agent and the Lenders a report of a reputable insurance broker with
respect to such insurance and such supplemental reports with respect thereto as

requirements of all Laws and all orders, writs, injunctions and decrees
applicable to it or to its business or property, except in such instances in
which (a) such requirement of Law or order, writ, injunction or decree is being
contested in good faith by appropriate proceedings diligently conducted; or (b)

Material Adverse Effect.

in which full, true and correct entries shall be made of all financial
transactions and matters involving the assets and business of either Borrower or
such Subsidiary, as the case may be and in a form in which financial statements
conforming with GAAP can be generated; and (b) maintain such books of record and
account in material conformity with all applicable requirements of any
Governmental Authority having regulatory jurisdiction over either Borrower or
such Subsidiary, as the case may be.

or abstracts therefrom, and to discuss its affairs, finances and accounts with
its officers and independent public accountants provided that in the case of any
meeting with such accountants, representatives of the Loan Parties may be
present (in the case of representatives and independent contractors of the
Agents, all at the expense of the Borrowers) and in each case at such reasonable
times during normal business hours and as often as may be reasonably desired,
upon reasonable advance notice to the Borrowers; provided that when an Event of
Default exists the Administrative Agent or any Lender (or any of their
respective representatives or independent contractors) may do any of the
foregoing at the expense of the Borrowers at any time during normal business

Real Property; obtain and renew all material Environmental Permits applicable to
its operations and Real Property; and conduct all Responses required by, and in
accordance with, Environmental Laws; provided that no Loan Party shall be
required to undertake any Response to the extent that its obligation to do so is
being contested in good faith and by proper proceedings and appropriate reserves
are being maintained with respect to such circumstances in accordance with GAAP.

      (b) If a Default caused by reason of a breach of Section 5.09 or Section
6.12(a) shall have occurred and be continuing for more than 20 days without the
Companies commencing activities reasonably likely to cure such Default in
accordance with Environmental Laws, at the written request of the Administrative
Agent or the Required Lenders through the Administrative Agent, provide to the
Lenders within 60 days after such request, at the expense of the Borrowers, an
environmental assessment report regarding the matters which are the subject of
such Default, including, where appropriate, soil and/or groundwater sampling,
prepared by an environmental consulting firm and, in the form and substance,
reasonably acceptable to the Administrative Agent and indicating the presence or
absence of Hazardous Materials and the estimated cost of any compliance or
Response to address them.

      (c) Each Loan Party that is an owner of Mortgaged Property shall not use,
store, handle or install nor permit to be used, stored, handled or installed in
the Mortgaged Property any Hazardous Materials, other than in compliance with

jurisdictions as may be reasonably requested by the Administrative Agent or the
Collateral Agent.

      (c) Promptly grant to the Collateral Agent, within 60 days of the
acquisition thereof, a security interest in and Mortgage on each Real Property
owned in fee by such Loan Party that is acquired by such Loan Party after the
Closing Date and that, together with any improvements thereon, individually has
a fair market value of at least $500,000, as additional security for the Secured
Obligations (unless the subject property is already mortgaged to a third party
to the extent permitted by Section 7.01). Such Mortgages shall be granted
pursuant to documentation reasonably satisfactory in form and substance to the
Administrative Agent and the Collateral

                                      -96-

Agent and shall constitute valid and enforceable perfected Liens subject only to
Permitted 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 reasonably require to
confirm the validity, perfection and priority of the Lien of any existing
Mortgage or new Mortgage against such after-acquired Real Property (including a
Title Policy, a Survey and local counsel opinion (in form and substance
reasonably satisfactory to the Administrative Agent and the Collateral Agent) in
respect of such Mortgage). Notwithstanding the foregoing, in the event the Loan
Parties acquire AMR Brockton, L.L.C. as set forth in the last paragraph of the
definition of "Permitted Acquisition" and the existing mortgage upon the real
property located at 45 Industrial Blvd, Lot 7A, Brockton, Massachusetts owned by
AMR Brockton, L.L.C. in effect on the date of this Agreement is not discharged
in connection with such acquisition, the Loan Parties shall not be required to
deliver a Mortgage and related documents and instruments that would otherwise be
required by this paragraph with respect to such property until such time as such
existing mortgage is discharged.

      6.14 SECURITY INTERESTS; FURTHER ASSURANCES. Promptly, upon the reasonable
request of the Administrative Agent or the Collateral Agent, at the Borrowers'
expense, execute, acknowledge and deliver, or cause the execution,
acknowledgment and delivery of, and thereafter register, file or record, or
cause to be registered, filed or recorded, in an appropriate governmental
office, any document or instrument supplemental to or confirmatory of the
Security Documents or otherwise deemed by the Administrative Agent or the
Collateral Agent reasonably necessary or desirable for the continued validity,
perfection and priority of the Liens on the Collateral covered thereby subject
to no other Liens except Permitted Liens or as permitted by the applicable Loan
Document, or use reasonable efforts to obtain any consents or waivers as may be
necessary or appropriate in connection therewith. Deliver or cause to be
delivered to the Administrative Agent and the Collateral Agent from time to time
such other documentation, consents, authorizations, approvals and orders in form
and substance reasonably satisfactory to the Administrative Agent and the
Collateral Agent as the Administrative Agent and the Collateral Agent shall
reasonably deem necessary to perfect or maintain the Liens on the Collateral
pursuant to the Security Documents. Upon the exercise by the Administrative
Agent or the Collateral Agent of any power, right, privilege or remedy pursuant
to any Loan Document which requires any consent, approval, registration,
qualification or authorization of any Governmental Authority execute and deliver
all applications, certifications, instruments and other documents and papers
that the Administrative Agent or the Collateral Agent may reasonably require. If
the Administrative Agent, the Collateral Agent or the Required Lenders determine
that they are required by a Requirement of Law to have appraisals prepared in
respect of the Real Property of any Loan Party constituting Collateral, the
Borrowers shall provide to the Administrative Agent appraisals that satisfy the
applicable requirements of the Real Estate Appraisal Reform Amendments of FIRREA
and are otherwise in form and substance reasonably satisfactory to the
Administrative Agent and the Collateral Agent.

Loan Party's legal name, (ii) in the location of any Loan Party's chief
executive office, (iii) in any

                                      -97-

shall have given the Collateral Agent and the Administrative Agent not less than
10 days' prior written notice (in the form of an Officers' Certificate), or such
lesser notice period agreed to by the Collateral Agent, of its intention so to
do, clearly describing such change and providing such other information in
connection therewith as the Collateral Agent or the Administrative Agent may
reasonably request and (B) it shall have taken all action reasonably
satisfactory to the Collateral Agent to maintain the perfection and priority of
the security interest of the Collateral Agent for the benefit of the Secured
Parties in the Collateral, if applicable. Each Loan Party agrees to promptly
provide the Collateral Agent with certified Organization Documents reflecting
any of the changes described in the preceding sentence. Each Loan Party also
agrees to promptly notify the Collateral Agent of any change in the location of
any office in which it maintains books or records relating to Collateral owned
by it.

      6.16 POST-CLOSING COLLATERAL MATTERS. Execute and deliver the documents
and complete the tasks set forth on Schedule 6.16, in each case within the time
limits specified on such schedule.

      the L/C Issuer in proportion to the respective amounts described in this
      clause (d) held by them; and

            (e) Last, the balance, if any, after all of the Obligations have

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate
undrawn amount of Letters of Credit pursuant to clause (e) above shall be
applied to satisfy drawings under such Letters of Credit as they occur. If any
amount remains on deposit as Cash Collateral after all Letters of Credit have

the other Obligations, if any, in the order set forth above.

shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing
(including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or
otherwise authenticated by the proper Person. Each also may rely upon any
statement made to it orally or by telephone and believed by it to have been made
by the proper Person, and shall not incur any liability for relying thereon. In
determining compliance with any condition hereunder to the making of a Loan, or
the issuance of a Letter of Credit, that by its terms must be fulfilled

                                      -119-
<PAGE>

to the satisfaction of a Lender or the L/C Issuer, each Agent may presume that
such condition is satisfactory to such Lender or the L/C Issuer unless such
Agent shall have received notice to the contrary from such Lender or the L/C
Issuer prior to the making of such Loan or the issuance of such Letter of
Credit. Each Agent may consult with legal counsel (who may be counsel for the
Borrowers), independent accountants and other experts 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 experts.

      9.05 DELEGATION OF DUTIES. Each Agent may perform any and all of its
duties and exercise its rights and powers hereunder or under any other Loan
Document by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may
perform any and all of its duties and exercise its rights and powers by or
through their respective Related Parties. The exculpatory provisions of this
Article shall apply to any such sub-agent and to the Related Parties 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 the Agents.

      9.06 RESIGNATION OF AGENT. Each Agent may at any time give notice of its
resignation to the Lenders, the L/C Issuer and the Borrowers. Upon receipt of
any such notice of resignation, the Required Lenders shall have the right, with
the written consent of the Borrowers, to appoint a successor, which shall be a
bank with an office in the United States, or an Affiliate of any such bank with
an office in the United States. If no such successor shall have been so
appointed by the Required Lenders and the Borrowers 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 and the L/C
Issuer, appoint a successor Agent meeting the qualifications set forth above;
provided that if the Agent shall notify the Borrowers and the Lenders that no
qualifying Person has accepted such appointment, then such resignation shall
nonetheless become effective in accordance with such notice and (1) the retiring
Agent shall be discharged from its duties and obligations hereunder and under
the other Loan Documents (except that in the case of any collateral security
held by the Agent on behalf of the Lenders or the L/C Issuer under any of the
Loan Documents, the retiring Agent shall continue to hold such collateral
security until such time as a successor Agent is appointed) and (2) all
payments, communications and determinations provided to be made by, to or
through the Agent shall instead be made by or to each Lender and the L/C Issuer
directly, until such time as the Required Lenders appoint a successor Agent as
provided for above in this Section. Upon the acceptance of a successor's
appointment as Agent hereunder and upon the execution and filing or recording of
such financing statements, or amendments thereto, and such amendments or
supplements to the Mortgages, and such other instruments or notices, as may be
necessary, or as the Required Lenders may reasonably request, in order to
continue the perfection of the Liens granted or purported to be granted by the
Security Documents, such successor shall succeed to and become vested with all
of the rights, powers, privileges and duties of the retiring (or retired) Agent,
and the retiring Agent shall be discharged from all of its duties and
obligations hereunder or under the other Loan Documents (if not already
discharged therefrom as provided above in this Section). The fees payable by the
Borrowers to a successor Agent shall be the same as those payable to its
predecessor unless otherwise agreed in writing between the Borrowers and such
successor. After the retiring Agent's resignation hereunder and under the other
Loan Documents, the provisions of this Article and

                                      -120-
<PAGE>

Section 10.04 shall continue in effect for the benefit of such retiring Agent,
its sub-agents and their respective Related Parties in respect of any actions
taken or omitted to be taken by any of them while the retiring Administrative
Agent was acting as Agent.

      9.07 NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender and the L/C
Issuer acknowledges that it has, independently and without reliance upon any
Agent or any other Lender or any of their Related Parties 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 and the L/C
Issuer also acknowledges that it will, independently and without reliance upon
any Agent or any other Lender or any of their Related Parties 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 any related agreement or any
document furnished hereunder or thereunder.

      9.08 NO OTHER DUTIES, ETC. Anything herein to the contrary
notwithstanding, none of the Bookrunners, Arrangers or Syndication Agent listed
on the cover page hereof shall have any powers, duties or responsibilities under
this Agreement or any of the other Loan Documents, except in its capacity, as
applicable, as an Agent, a Lender or the L/C Issuer hereunder.

      9.09 AGENT MAY FILE PROOFS OF CLAIM. In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceeding relative to any Loan Party,
any Agent (irrespective of whether the principal of any Loan or L/C Obligation
shall then be due and payable as herein expressed or by declaration or otherwise
and irrespective of whether such Agent shall have made any demand on any Loan
Party) shall be entitled and empowered, by intervention in such proceeding or
otherwise:

            (a) to file and prove a claim for the whole amount of the principal
      and interest owing and unpaid in respect of the Loans, L/C Obligations and
      all other Obligations that are owing and unpaid and to file such other
      documents as may be necessary or advisable in order to have the claims of
      the Lenders, the L/C Issuer and the Administrative Agent (including any
      claim for the reasonable compensation, expenses, disbursements and
      advances of the Lenders, the L/C Issuer and the Administrative Agent and
      their respective agents and counsel and all other amounts due the Lenders,
      the L/C Issuer and the Administrative Agent under Sections 2.03(i) and
      (j), 2.09 and 10.04) allowed in such judicial proceeding; and

            (b) to collect and receive any monies or other property payable or
      deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender and the L/C Issuer to make such payments to the Administrative Agent
and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders and the L/C Issuer, to pay to the
Administrative Agent any amount due for the reasonable compensation, expenses,
disbursements and advances of the Administrative Agent and its agents and
counsel, and any other amounts due the Administrative Agent under Sections 2.09
and 10.04.

                                      -121-
<PAGE>

      Nothing contained herein shall be deemed to authorize the Administrative
Agent to authorize or consent to or accept or adopt on behalf of any Lender or
the L/C Issuer any plan of reorganization, arrangement, adjustment or
composition affecting the Obligations or the rights of any Lender or to
authorize the Administrative Agent to vote in respect of the claim of any Lender
in any such proceeding.

      9.10 COLLATERAL AND GUARANTY MATTERS. The Lenders and the L/C Issuer
irrevocably authorize each of the Administrative Agent and Collateral Agent, at
its option and in its discretion,

            (a) to release any Lien on any property granted to or held by the
      Collateral Agent under any Loan Document (i) upon termination of the
      Aggregate Commitments and payment in full of all Obligations (other than
      contingent indemnification obligations) and the expiration or termination
      of all Letters of Credit (other than Letters of Credit which have been
      collateralized in cash or otherwise to the satisfaction of the L/C
      Lender), (ii) that is sold or to be sold as part of or in connection with
      any sale permitted hereunder or under any other Loan Document, or (iii)
      subject to Section 10.01, if approved, authorized or ratified in writing
      by the Required Lenders;

            (b) to subordinate any Lien on any property granted to or held by
      the Collateral Agent under any Loan Document to the holder of any Lien on
      such property that is permitted by Section 7.01(i); and

            (c) to release any Guarantor from its obligations under the Guaranty
      if such Person ceases to be a Subsidiary as a result of a transaction
      permitted hereunder.

      Upon request by the Administrative Agent or Collateral Agent at any time,
the Required Lenders will confirm in writing the Administrative Agent's
Collateral Agent's, as the case may be, authority to release or subordinate its
interest in particular types or items of property, or to release any Guarantor
from its obligations under the Guaranty pursuant to this Section 9.10.

      10.01 AMENDMENTS, ETC. No amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent to any departure by Loan
Party therefrom, shall be effective unless in writing signed by the Required
Lenders and the Borrowers or the applicable Loan Party, as the case may be, and
acknowledged by the Administrative Agent, and each such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given; provided that no such amendment, waiver or consent shall:

the relevant Additional Term Loans pursuant to Section 2.14.

more of such other Lenders whose consent is required is not obtained, then the
Borrowers 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

Issuer, the Administrative Agent or the Collateral Agent to exercise, and no
delay by any such Person in exercising, any right, remedy, power or privilege

any Indemnitee is a party thereto; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses (x) are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee or (y) result from a claim
brought by either Borrower or any other Loan Party against an Indemnitee for
breach of such Indemnitee's obligations hereunder or under any other Loan
Document, if such Loan Party has obtained a final and nonappealable judgment in
its favor on such claim as determined by a court of competent jurisdiction.

      (c) Reimbursement by Lenders. To the extent that the Loan Parties for any
reason fail to indefeasibly pay any amount required under subsection (a) or (b)

severally agrees to pay to the Administrative Agent (or any such sub-agent), the
Collateral Agent, the L/C Issuer or such Related Party, 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 the Administrative Agent (or any such sub-agent) or the L/C Issuer in
its capacity as such, or against any Related Party of any of the foregoing
acting for the Administrative Agent (or any such sub-agent), the Collateral
Agent or L/C Issuer in connection with such capacity. The obligations of the

by applicable law, the Loan Parties shall not assert, and hereby waive, any

arising out of, in connection with, or as a result of, this Agreement, any other
Loan Document or any agreement or instrument contemplated hereby, the
transactions contemplated hereby or thereby, any Loan or Letter of Credit or the
use of the proceeds thereof. No Indemnitee referred to in subsection (b) above

      10.05 PAYMENTS SET ASIDE. To the extent that any payment by or on behalf
of the Borrowers is made to the Administrative Agent, the Collateral Agent, the
L/C Issuer or any Lender, or the Administrative Agent, the Collateral Agent, the
L/C Issuer or any Lender exercises its right of setoff, and such payment or the
proceeds of such setoff or any part thereof is subsequently invalidated,
declared to be fraudulent or preferential, set aside or required (including
pursuant to any settlement entered into by the Administrative Agent, the
Collateral Agent, the L/C Issuer or such Lender in its discretion) to be repaid
to a trustee, receiver or any other party, in connection with any proceeding
under any Debtor Relief Law or otherwise, then (a) to the extent of such
recovery, the obligation or part thereof originally intended to be satisfied
shall be revived and continued in full force and effect as if such payment had
not been made or such setoff had not occurred, and (b) each Lender and the L/C
Issuer severally agrees to pay to the Administrative Agent and the Collateral
Agent upon demand its applicable share (without duplication) of any amount so
recovered from or repaid by the Administrative Agent and the Collateral Agent,

made at a rate per annum equal to the Federal Funds Rate from time to time in
effect. The obligations of the Lenders and the L/C Issuer under clause (b) of
the preceding sentence shall

                                      -127-

survive the payment in full of the Obligations and the termination of this

upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby, Participants to the extent provided in subsection (d)
of this Section and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent, the L/C Issuer and the Lenders) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

      (b) Assignments by Lenders. Any Lender may at any time assign to one or
more Eligible Assignees all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans
(including for purposes of this subsection (b), participations in L/C
Obligations and in Swing Line Loans) at the time owing to it); provided that

            (i) (A) with respect to any assignment of any Revolving Loan
      Commitment and/or Revolving Loans, except in the case of an assignment of
      the entire remaining amount of the assigning Lender's Revolving Loan
      Commitment and the Revolving Loans at the time owing to it or in the case
      of an assignment to a Lender or an Affiliate of a Lender or an Approved
      Fund with respect to a Lender, the aggregate amount of the Revolving Loan
      Commitment (which for this purpose includes Revolving Loans outstanding
      thereunder) or, if the Revolving Loan Commitment is not then in effect,
      the principal outstanding balance of the Revolving 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 or, if "Trade Date" is specified in the
      Assignment and Assumption, as of the Trade Date, shall not be less than
      $5,000,000 unless each of the Administrative Agent and, so long as no
      Event of Default has occurred and is continuing, the Borrowers otherwise
      consent in writing (each such consent not to be unreasonably withheld or
      delayed);

            (B) with respect to any assignment of any Term Loan Commitment
      and/or Term Loans, except in the case of an assignment of the entire
      remaining amount of the assigning Lender's Term Loan Commitment and the
      Term Loans at the time owing to it or in the case of an assignment to a
      Lender or an Affiliate of a Lender or an Approved Fund with respect to a
      Lender, the aggregate amount of the Term Loan Commitment or,

                                      -128-
<PAGE>

      if the Term Loan Commitment is not then in effect, the principal
      outstanding balance of the Term 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 or, if "Trade Date" is specified in the Assignment
      and Assumption, as of the Trade Date, shall not be less than $1,000,000
      unless each of the Administrative Agent and so long as no Event of Default
      has occurred and is continuing, the Borrowers otherwise consent in writing
      (such consent not to be unreasonably withheld or delayed);

            (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 with respect to the Loans or the Commitment assigned,
      except that this clause (ii) shall not apply to rights in respect of Swing
      Line Loans and shall not prohibit any Lender from assigning all or a
      portion of its rights and obligations among its Revolving Loan Commitment
      and Revolving Loans, on the one hand, and its Term Loan Commitment and
      Term Loans, on the other hand, on a non-pro rata basis;

            (iii) (A) any assignment of a Revolving Loan Commitment or Revolving
      Loans must be approved by the Administrative Agent, the L/C Issuer and,
      the Swing Line Lender unless the Person that is the proposed assignee is
      itself a Lender (whether or not the proposed assignee would otherwise
      qualify as an Eligible Assignee);

            (B) any assignment of a Term Loan Commitment or Term Loans must be
      approved by the Administrative Agent (such approval not to be unreasonably
      withheld or delayed) unless the Person that is the proposed assignee is
      itself a Lender, or an Approved Fund with respect to the assigning Lender
      (whether or not the proposed assignee would otherwise qualify as an
      Eligible Assignee) (it being understood and agreed that any assignment of
      a Term Loan Commitment or Term Loans shall not at any time require the
      approval of the Borrowers); and

            (iv) the parties of each assignment shall execute and deliver to the
      Administrative Agent an Assignment and Assumption, together with the
      Assignment Fee as calculated below, and the Eligible Assignee, if it shall
      not be a Lender, shall deliver to the Administrative Agent an
      Administrative Questionnaire;

            a processing and recordation fee (an "Assignment Fee") will be
            payable to the Administrative Agent in the amount of $2,500 for each
            assignment; provided, however, that in the event of two or more
            concurrent assignments to members of the same Assignee Group (which
            may be effected by a suballocation of an assigned amount among
            members of such Assignee Group) or two or more concurrent
            assignments by members of the same Assignee Group to a single
            Eligible Assignee (or to an Eligible Assignee and members of its
            Assignee Group), the Assignment Fee will be $2,500 plus the amount
            set forth below:

of such Assignee Group, as applicable)
</TABLE>

            For purposes hereof, "Assignee Group" means two or more Eligible
            Assignees that are Affiliates of one another or two or more Approved
            Funds managed by the same investment advisor.

Subject to acceptance and recording thereof by the Administrative Agent pursuant
to subsection (c) of this Section, from and after the effective date specified
in each Assignment and Assumption, the Eligible Assignee thereunder shall be a
party to this Agreement and, to the extent of the interest assigned by such
Assignment and Assumption, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto) but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04 with
respect to facts and circumstances occurring prior to the effective date of such
assignment. Upon request, the Borrowers (at their expense) shall execute and
deliver the applicable Note to the assignee Lender. Any assignment or transfer
by a Lender of rights or obligations under this Agreement that does not comply
with this subsection shall be treated for purposes of this Agreement as a sale
by such Lender of a participation in such rights and obligations in accordance
with subsection (d) of this Section.

      (c) Register. The Administrative Agent, acting solely for this purpose as
an agent of the Borrowers, shall maintain at the Administrative Agent's Office 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 Commitments of,
and principal amounts of the Loans and L/C Obligations owing to, each Lender
pursuant to the terms hereof from time to time (the "Register"). The entries in
the Register shall be conclusive, and the Borrowers, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by each of the Borrowers and the L/C Issuer at any
reasonable time and from time to time upon reasonable prior notice. In addition,
at any time that a request for a consent for a material or substantive change to
the Loan Documents is pending, any Lender wishing to consult with other Lenders
in connection therewith may request and receive from the Administrative Agent a
copy of the Register.

                                      -130-

      (d) Participations. Any Lender may at any time, without the consent of, or
notice to, the Borrowers or the Administrative Agent, sell participations to any
Person (other than a natural person or the Permitted Holders or the Borrowers or
any of the Permitted Holders' or the Borrowers' Affiliates or Subsidiaries)
(each, a "Participant") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans (including such Lender's participations in L/C Obligations
and/or Swing Line 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) the Borrowers, the Administrative Agent, the Lenders
and the L/C Issuer shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under this Agreement.

      Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, waiver or other modification described in the first proviso to
Section 10.01 that affects such Participant. Subject to subsection (e) of this
Section, the Borrowers agree that each Participant shall be entitled to the
benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to subsection (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 10.08(a) as though it were a Lender,
provided that (i) such Participant shall be subject to Section 10.08(b) as
though it were a Lender and (ii) such Participant agrees to be subject to
Section 2.13 as though it were a Lender.

      (e) Limitations upon Participant Rights. A Participant shall not be
entitled to receive any greater payment under Section 3.01, 3.04 or 3.05 than
the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to
such Participant is made with the Borrowers' prior written consent.

      (f) Certain Pledges. Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement
(including under its Note(s), if any) to secure obligations of such Lender,
including without limitation (i) any pledge or assignment to secure obligations
to a Federal Reserve Bank and (ii) in the case of any Lender that is a Fund, any
pledge or assignment to any holders of obligations owed, or securities issued,
by such Lender including to any trustee for, or any other representative of,
such holders; provided that, in each case, no such pledge or assignment of a
security interest shall release such Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

      (g) Electronic Execution of Assignments. The words "execution," "signed,"
"signature," and words of like import in any Assignment and Assumption shall be
deemed to include electronic signatures or the keeping of records in electronic
form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in
any applicable law, including the Federal Electronic Signatures in Global and
National Commerce Act,

                                     -131-
<PAGE>

the New York State Electronic Signatures and Records Act, or any other similar
state laws based on the Uniform Electronic Transactions Act.

      (h) Special Purpose Funding Vehicles. Notwithstanding anything to the
contrary contained herein, any Lender (a "Granting Lender") may grant to a
special purpose funding vehicle identified as such in writing from time to time
by the Granting Lender to the Administrative Agent and the Borrowers (an "SPC")
the option to provide all or any part of any Committed Loan that such Granting
Lender would otherwise be obligated to make pursuant to this Agreement; provided
that (i) nothing herein shall constitute a commitment by any SPC to fund any
Committed Loan, and (ii) if an SPC elects not to exercise such option or
otherwise fails to make all or any part of such Committed Loan, the Granting
Lender shall be obligated to make such Committed Loan pursuant to the terms
hereof or, if it fails to do so, to make such payment to the Administrative
Agent as is required under Section 2.12(b)(ii). Each party hereto hereby agrees
that (i) neither the grant to any SPC nor the exercise by any SPC of such option
shall increase the costs or expenses or otherwise increase or change the
obligations of the Borrowers under this Agreement (including its obligations
under Section 3.04), (ii) no SPC shall be liable for any indemnity or similar
payment obligation under this Agreement for which a Lender would be liable, and
(iii) the Granting Lender shall for all purposes, including the approval of any
amendment, waiver or other modification of any provision of any Loan Document,
remain the lender of record hereunder. The making of a Committed Loan by an SPC
hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Committed Loan were made by such Granting Lender. In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior debt of any SPC, it will not institute against, or join
any other Person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency, or liquidation proceeding under the
laws of the United States or any State thereof; provided, however, that (i) in
the case of any Loan Party, the Granting Lender is in compliance with its
obligations to Loan Parties hereunder and (ii) each Granting Lender designating
any SPC hereby agrees to indemnify, save and hold harmless each other party
hereto for any loss, cost, damage or expense arising out of its inability to
institute such a proceeding against such SPC during such period of forbearance.
Notwithstanding anything to the contrary contained herein, any SPC may (i) with
notice to, but without prior consent of the Borrowers and the Administrative
Agent and with the payment of a processing fee of $3,500, assign all or any
portion of its right to receive payment with respect to any Committed Loan to
the Granting Lender and (ii) subject to Section 10.07, disclose on a
confidential basis any non-public information relating to its funding of Loans
to any rating agency, commercial paper dealer or provider of any surety or
Guarantee or credit or liquidity enhancement to such SPC.

      (i) Resignation as L/C Issuer or Swing Line Lender After Assignment.
Notwithstanding anything to the contrary contained herein, if at any time Bank
of America assigns all of its Revolving Loan Commitment and Revolving Loans
pursuant to subsection (b) above, Bank of America may, (i) upon 30 days' notice
to the Borrowers and the Lenders, resign as L/C Issuer and/or (ii) upon 30 days'
notice to the Borrowers, resign as Swing Line Lender. In the event of any such
resignation as L/C Issuer or Swing Line Lender, the Borrowers shall be entitled
to appoint from among the Revolving Loan Lenders (and with the consent of the
applicable Revolving Loan Lender) a successor L/C Issuer or Swing Line Lender
hereunder; provided that no

                                      -132-
<PAGE>

failure by the Borrowers to appoint any such successor shall affect the
resignation of Bank of America as L/C Issuer or Swing Line Lender, as the case
may be. If Bank of America resigns as L/C Issuer, it shall retain all the rights
and obligations of the L/C Issuer hereunder with respect to all Letters of
Credit outstanding as of the effective date of its resignation as L/C Issuer and
all L/C Obligations with respect thereto (including the right to require the
Revolving Loan Lenders to make Base Rate Revolving Loans or fund risk
participations in Unreimbursed Amounts pursuant to Section 2.03(c)). If Bank of
America resigns as Swing Line Lender, it shall retain all the rights of the
Swing Line Lender provided for hereunder with respect to Swing Line Loans made
by it and outstanding as of the effective date of such resignation, including
the right to require the Revolving Loan Lenders to make Base Rate Revolving
Loans or fund risk participations in outstanding Swing Line Loans pursuant to
Section 2.04(c).

      10.07 TREATMENT OF CERTAIN INFORMATION; CONFIDENTIALITY. Each of the
Administrative Agent, the Lenders and the L/C Issuer agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its Affiliates and to its and its Affiliates' respective
partners, directors, officers, employees, agents, advisors and representatives
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential), (b) to the extent requested by any regulatory
authority purporting to have jurisdiction over it (including any self-regulatory
authority, such as the National Association of Insurance Commissioners), (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process; provided, unless specifically prohibited by applicable
law or court order, such Agent, the L/C Issuer or such Lender, as applicable,
shall make reasonable efforts to notify the Borrowers of any request thereof,
(d) to any other party hereto, (e) in connection with the exercise of any
remedies hereunder or under any other Loan Document or any action or proceeding
relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) to (i) any assignee of or Participant in, or
any prospective assignee of or Participant in, any of its rights or obligations
under this Agreement, provided such assignee, Participant or prospective
assignee or Participant agrees to be bound by the provisions of this Section or
(ii) any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to the Borrowers and their obligations that
agrees to be bound by the provisions of this Section or (g) with the consent of
the Borrowers.

      "Information" means information concerning Holdings or any of its direct
or indirect shareholders, or any of their respective employees, directors, or
Subsidiaries, or Affiliates (including without limitation the Permitted Holders)
received by any Agent, the L/C Issuer or any Lender on a confidential basis from
the Borrowers or any other person under or pursuant to this Agreement or any
other Loan Document, including without limitation financial terms and financial
and organizational information contained in any documents, statements,
certificates, materials or information furnished, or to be furnished, by or on
behalf of any Borrower or any other person on a confidential basis in connection
with this Agreement and the Loan Documents, but does not include any such
information that (i) is publicly available at the time of disclosure or becomes
publicly available other than as a result of a breach of this Section or (ii)
becomes available to any Agent, the L/C Issuer or any Lender on a
nonconfidential basis from a source other than the Borrowers or any of their
direct or indirect shareholders, or any of their respective employees,
directors, Subsidiaries or Affiliates (including, without limitation, the
Permitted Holders) or any of their respective agents or representatives.

                                      -133-
<PAGE>

      10.08 RIGHT OF SETOFF.

      (a) If an Event of Default shall have occurred and be continuing, each
Lender, the L/C Issuer and each of their respective Affiliates are hereby
authorized at any time and from time to time, to the fullest extent permitted by
applicable law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final, in whatever currency) at any time held and
other obligations (in whatever currency) at any time owing by such Lender, the
L/C Issuer or any such Affiliate to or for the credit or the account of the
Borrowers or any other Loan Party against any and all of the obligations of the
Borrowers or such Loan Party now or hereafter existing under this Agreement or
any other Loan Document to such Lender or the L/C Issuer, irrespective of
whether or not such Lender or the L/C Issuer shall have made any demand under
this Agreement or any other Loan Document and although such obligations of the
Borrowers or such Loan Party may be contingent or unmatured or are owed to a
branch or office of such Lender or the L/C Issuer different from the branch or
office holding such deposit or obligated on such indebtedness. The rights of
each Lender, the L/C Issuer and their respective Affiliates under this Section
are in addition to other rights and remedies (including other rights of setoff)
that such Lender, the L/C Issuer or their respective Affiliates may have. Each
Lender and the L/C Issuer agrees to notify the Borrowers and the Administrative
Agent promptly after any such setoff and application, provided that the failure
to give such notice shall not affect the validity of such setoff and
application.

      (b) No Lender, or L/C Issuer, or any of their respective Affiliates will
exercise or claim any right of set-off or banker's lien which would violate
Section 30.2.5 of the Medicare Claims Processing Manual, and each Lender, L/C
Issuer and their Affiliates hereby waives any and all such rights and liens they
may have to set-off that would otherwise violate such provision, provided that,
without limitation of the foregoing, any Lender shall be entitled to debit any
lockbox account(s) maintained by such Lender for all usual and customary service
charges, transfer fees and account maintenance fees, only, of such Lender in
connection with such lockbox account(s) and such Lender shall, if any third
party checks or other receipts deposited in the lockbox(es) are dishonored, have
the right to charge any such returned or dishonored items against such lockbox
account(s) or to demand reimbursement therefore from Borrowers.

      10.09 INTEREST RATE LIMITATION. Notwithstanding anything to the contrary
contained in any Loan Document, the interest paid or agreed to be paid under the
Loan Documents shall not exceed the maximum rate of non-usurious interest
permitted by applicable Law (the "Maximum Rate"). If the Administrative Agent or
any Lender shall receive interest in an amount that exceeds the Maximum Rate,
the excess interest shall be applied to the principal of the Loans or, if it
exceeds such unpaid principal, refunded to the Borrowers. In determining whether
the interest contracted for, charged, or received by the Administrative Agent or
a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by
applicable Law, (a) characterize any payment that is not principal as an
expense, fee, or premium rather than interest, (b) exclude voluntary prepayments
and the effects thereof and (c) amortize, prorate, allocate, and spread in equal
or unequal parts the total amount of interest throughout the contemplated term
of the Obligations hereunder.

      10.10 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement may be
executed in counterparts (and by different parties hereto in different
counterparts), each of which shall

                                      -134-
<PAGE>

constitute an original, but all of which when taken together shall constitute a
single contract. This Agreement and the other Loan Documents 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. Except as provided in Section 4.01, 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 that, when taken together, bear the signatures of each of
the other parties hereto. 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.

      10.11 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default at the time of any Credit Extension, and shall continue in full
force and effect as long as any Loan or any other Obligation hereunder shall
remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

      10.12 SEVERABILITY. If any provision of this Agreement or the other Loan
Documents is held to be illegal, invalid or unenforceable, (a) the legality,
validity and enforceability of the remaining provisions of this Agreement and
the other Loan Documents shall not be affected or impaired thereby and (b) the
parties shall endeavor in good faith negotiations to replace the illegal,
invalid or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      10.13 REPLACEMENT OF LENDERS. If any Lender requests compensation under
Section 3.04, or if the Borrowers are required to pay any additional amount to
any Lender or any Governmental Authority for the account of any Lender pursuant
to Section 3.01, or if any Lender is a Defaulting Lender, then the Borrowers
may, at their 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, and
consents required by, Section 10.06), all of its interests, rights and
obligations under this Agreement and the related Loan Documents to an assignee
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment), provided that:

            (a) the Borrowers shall have paid to the Administrative Agent the
      assignment fee specified in Section 10.06(b);

            (b) such Lender shall have received payment of an amount equal to
      the outstanding principal of its Loans and L/C Advances, accrued interest
      thereon, accrued fees and all other amounts payable to it hereunder and
      under the other Loan Documents (including any amounts under Section 3.05)
      from the assignee (to the extent of such

                                      -135-
<PAGE>

      outstanding principal and accrued interest and fees) or the Borrowers (in
      the case of all other amounts);

            (c) in the case of any such assignment resulting from a claim for
      compensation under Section 3.04 or payments required to be made pursuant
      to Section 3.01, such assignment will result in a reduction in such
      compensation or payments thereafter; and

            (d) such assignment does not conflict with applicable Laws.

      A Lender shall not be required to make any such assignment or delegation
if, prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrowers to require such assignment and delegation
cease to apply.

      10.14 GOVERNING LAW; JURISDICTION; ETC.

      (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

      (b) SUBMISSION TO JURISDICTION. THE BORROWERS AND EACH OTHER LOAN PARTY
IRREVOCABLY AND UNCONDITIONALLY SUBMIT, FOR ITSELF AND ITS PROPERTY, TO THE
NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW
YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF
SUCH STATE, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE
PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT
OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK
STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE 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 IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT
THAT THE ADMINISTRATIVE AGENT, ANY LENDER OR THE L/C ISSUER MAY OTHERWISE HAVE
TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN

hereinafter defined) and the Administrative Agent (for itself and not on behalf
of any Lender) hereby notifies the Borrowers that pursuant to the requirements
of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26,
2001)) (the "Act"), it is required to obtain, verify and record information that
identifies each Borrower, which information includes the name and address of
such Borrower and other information that will allow such Lender or the
Administrative Agent, as applicable, to identify such Borrower in accordance
with the Act.

      10.17 RIGHT OF CONTRIBUTION. If any Loan Party shall make an Excess
Payment (as defined below), such Loan Party shall have a right of contribution
from the other Loan Parties in an amount equal to the other Loan Parties'
Contribution Share (as defined below) of such Excess Payment; provided, that
such Loan Party shall not exercise any right or remedy under this Section 10.17

the amount paid by any Loan Party in excess of its Pro Rata Share of any
Obligations; (b) "Pro Rata Share" shall mean, for any Loan Party in respect of

subordinated, unmatured and unliquidated liabilities, but excluding the

the Loan Parties exceeds the amount of all of the debts and liabilities
(including contingent, subordi nated, unmatured and unliquidated liabilities,
but excluding the obligations of all the Loan Parties hereunder) of all the Loan
Parties; and (c) "Contribution Share" shall mean, for any Loan Party in respect
of any Excess Payment made by the any other Loan Party, the ratio (expressed as
a percentage) as of the date of such Excess Payment of (i) the amount by which
the aggregate present fair salable value of all of its assets and properties
exceeds the amount of all debts and liabilities of such Loan Party (including
contingent, subordi nated, unmature and unliquidated liabilities, but excluding
the obligations of such Loan Party hereunder) to (ii) the amount by which the
aggregate present fair salable value of all assets and other properties of all
the Loan Parties other than the maker of such Excess Payment exceeds the amount
of all of the debts and liabilities (including contingent, subordinated,
