then outstanding L/C Obligations, does not exceed at any time such Bank's
Commitment; provided that no Loan shall be made as a LIBOR Rate Loan with an
Interest Period ending after the Termination Date; and provided, further, that
in no event shall the Total Outstanding Extensions of Credit at any time exceed
the Total Commitments at such time.

     (b) Each Borrowing by the Borrower shall be in an aggregate principal
amount not less than $10,000,000 (in the case of LIBOR Rate Loans) or $5,000,000
(in the case of ABR Loans), or an integral multiple of $1,000,000 in excess
thereof and shall consist of Loans of the same Type made on the same day by the
Banks ratably according to their respective Revolving Percentages. Within the
limits of the applicable Commitments, the Borrower may borrow, prepay pursuant
to Section 4.6 and reborrow under this Section 2.1. The principal amount
outstanding on the Loans shall be due and payable on the Termination Date,
together with accrued and unpaid interest thereon.

     SECTION 2.2. Procedure for Revolving Loan Borrowing. (a) The Borrower may
borrow under the Commitments on any Business Day during the period from and
including the Closing Date to and excluding the Termination Date, provided that
the Borrower shall give the Administrative Agent irrevocable oral notice or
written notice pursuant to a notice of borrowing, in substantially the form of
Exhibit A hereto ("Notice of Borrowing") which shall be signed by the Borrower
and shall specify therein the requested (i) date of such Borrowing, (ii) Type of
Loans comprising such Borrowing, (iii) aggregate amount of such Borrowing and
(iv) the Interest Period for each such Loan, in the case of any LIBOR Rate Loan,

          (i) not later than 11:00 A.M. (New York City time) on the third
     Business Day prior to the date of the proposed Borrowing in the case of a
     LIBOR Rate Loan;

          (ii) not later than 11:00 A.M. (New York City time) on the Business
     Day immediately preceding the date of the proposed Borrowing in the case of
     an Early Funding ABR Loan; and


                                       22

<PAGE>

          (iii) not later than 11:00 A.M. (New York City time) on the same
     Business Day of the proposed Borrowing in the case of any other ABR Loan.

With respect to any oral notice of borrowing given by the Borrower, the Borrower
shall promptly thereafter confirm such notice in writing pursuant to a Notice of
Borrowing. Upon receipt of any such notice, the Administrative Agent shall
promptly notify each Bank thereof. Each Bank shall, before 1:00 P.M. (New York
City time) on the date of such Borrowing, make available to the Administrative
Agent at the Funding Office, in immediately available funds, such Bank's
applicable Revolving Percentage of such Borrowing; provided, however, that, in
the event of a requested ABR Loan with respect to which the Borrower has
delivered its Notice of Borrowing on the Business Day immediately preceding the
requested Borrowing Date (an "Early Funding ABR Loan"), each Bank shall make its
applicable Revolving Percentage of such Borrowing available before 10:00 A.M.
(New York City time) on the requested Borrowing Date. The Administrative Agent
shall, no later than 2:00 P.M. (New York City time) on such date (or no later
than 11:00 A.M. (New York City time), in the case of an Early Funding ABR Loan),
make available to the Borrower the proceeds of the Loans received by the
Administrative Agent hereunder by crediting such account of the Borrower which
the Administrative Agent and the Borrower shall from time to time designate.
Each Notice of Borrowing shall be irrevocable and binding on the Borrower.

     (b) Unless the Administrative Agent shall have received notice from a Bank
at least two hours prior to the applicable time described in clause (a) above by
which such Bank is required to deliver its funds to the Administrative Agent
with respect to any Borrowing that such Bank will not make available to the
Administrative Agent such Bank's applicable Revolving Percentage of such
Borrowing, the Administrative Agent may assume that such Bank has made such
portion available to the Administrative Agent on the date of such Borrowing in
accordance with Section 2.2(a) and the Administrative Agent may, in reliance
upon such assumption, make available to the Borrower on such date a
corresponding amount. If such amount is made available to the Administrative
Agent on a date after such date of Borrowing, such Bank shall pay to the
Administrative Agent on demand an amount equal to the product of (i) the daily
average Federal Funds Effective Rate during such period, times (ii) the amount
of such Bank's applicable Revolving Percentage of such Borrowing, times (iii) a
fraction, the numerator of which is the number of days that elapse from and
including such date of Borrowing to the date on which such Bank's applicable
Revolving Percentage of such Borrowing shall have become immediately available
to the Administrative Agent and the denominator of which is 360. A certificate
of the Administrative Agent submitted to any Bank with respect to any amounts
owing under this Section 2.2(b) shall be conclusive in the absence of manifest
error. If such Bank shall repay to the Administrative Agent such corresponding
amount, such amount so repaid shall constitute such Bank's Loan as part of such
Borrowing for purposes of this Agreement. If such Bank's applicable Revolving
Percentage of such Borrowing is not in fact made available to the Administrative
Agent by such Bank within one (1) Business Day of such date of Borrowing, the
Administrative Agent shall be entitled to recover such amount with interest
thereon at the rate per annum, equal to (i) the ABR (in the case of ABR Loans)
or (ii) the Federal Funds Effective Rate (in the case of LIBOR Rate Loans), on
demand, from the Borrower.

     (c) The failure of any Bank to make the Loan to be made by it as part of
any Borrowing shall not relieve any other Bank of its obligation, if any,
hereunder to make its Loan


                                       23

<PAGE>

on the date of such Borrowing, but no Bank shall be responsible for the failure
of any other Bank to make the Loan to be made by such other Bank on the date of
any Borrowing.

     SECTION 2.3. Minimum Tranches. All Borrowings, prepayments, conversions and
continuations of Loans hereunder and all selections of Interest Periods
hereunder shall be in such amounts and be made pursuant to such elections so
that, after giving effect thereto, the aggregate principal amount of the Loans
comprising each Tranche of LIBOR Rate Loans shall be equal to $10,000,000 or an
integral multiple of $1,000,000 in excess thereof.

     SECTION 2.4. Letters of Credit. (a) L/C Commitment.

          (i) Prior to the Closing Date, the Existing Issuing Banks have issued
     the Existing Letters of Credit which from and after the Closing Date shall
     constitute Letters of Credit hereunder.

          (ii) Subject to the terms and conditions hereof, each Issuing Bank, in
     reliance on the agreements of the other Banks set forth in Section 2.4(d),
     agrees to issue standby letters of credit (the "Letters of Credit") for the
     account of the Borrower in support of obligations (including, without
     limitation, performance, bid and similar bonding obligations and credit
     enhancement) of the Borrower and its Affiliates on any Business Day on or
     after the Closing Date and prior to the Termination Date in such form as
     may be approved from time to time by such Issuing Bank; provided that no
     Issuing Bank shall issue any Letter of Credit if, after giving effect to
     such issuance, (A) the L/C Obligations would exceed the L/C Commitment or
     (B) the Total Outstanding Extensions of Credit then outstanding would
     exceed the Total Commitments then in effect and provided, further, that
     neither JPMorgan Chase Bank, N.A. nor Wachovia Bank, National Association
     shall be required to issue Letters of Credit in excess of $37,500,000 at
     any time outstanding for each such Issuing Bank.

          (iii) Each Letter of Credit shall be denominated in Dollars and shall
     be a standby letter of credit issued to support obligations of the Borrower
     or any of its Affiliates, contingent or otherwise, and expire no later than
     the Maturity Date.

          (iv) Each Letter of Credit shall be subject to the Uniform Customs
     and, to the extent not inconsistent therewith, the laws of the State of New
     York.

          (v) No Issuing Bank shall at any time be obligated to issue any Letter
     of Credit hereunder if such issuance would conflict with, or cause such
     Issuing Bank or any L/C Participant to exceed any limits imposed on such
     Issuing Bank by any applicable Requirement of Law.

     (b) Procedure for Issuance of Letters of Credit. The Borrower may from time
to time request that an Issuing Bank issue a Letter of Credit by delivering to
such Issuing Bank at its address for notices specified herein an Application
therefor, completed to the satisfaction of such Issuing Bank, and such other
certificates, documents and other papers and information as such Issuing Bank
may reasonably request. Upon receipt of any Application, the Issuing Bank will
process such Application and the certificates, documents and other papers and
information delivered to it in connection therewith in accordance with its
customary procedures and shall


                                       24

<PAGE>

promptly issue the Letter of Credit requested thereby (but in no event shall any
Issuing Bank be required to issue any Letter of Credit earlier than two Business
Days after its receipt of the Application therefor and all such other
certificates, documents and other papers and information relating thereto) by
issuing the original of such Letter of Credit in a form satisfactory to the
Borrower to the beneficiary thereof or as otherwise may be agreed by such
Issuing Bank and Borrower. The relevant Issuing Bank shall furnish a copy of
such Letter of Credit to the Borrower promptly following the issuance thereof
and notify the Banks of the amount thereof.

     (c) Fees, Commissions and Other Charges.

          (i) The Borrower shall pay to the Administrative Agent, for the
     account of the relevant Issuing Bank and the L/C Participants, a letter of
     credit commission fee with respect to each Letter of Credit, computed for
     the period from the last L/C Fee Payment Date (or, if later, the date of
     issuance thereof) to the date upon which such payment is due hereunder at
     the rate per annum equal to the Applicable Margin for LIBOR Rate Loans then
     in effect, calculated on the basis of a 365- (or 366-, as the case may be)
     day year, of the aggregate amount available to be drawn under such Letter
     of Credit on the date on which such fee is calculated. The Borrower shall
     pay to the Administrative Agent, for the account of the relevant Issuing
     Bank, a fronting fee with respect to each Letter of Credit, computed for
     the period from the last L/C Fee Payment Date to the date upon which such
     payment is due hereunder at the rate per annum equal to 0.125%, calculated
     on the basis of a 365- (or 366-, as the case may be) day year, of the
     aggregate amount available to be drawn under such Letter of Credit on the
     date on which such fee is calculated. Such commissions and fronting fees
     shall be payable in arrears on each L/C Fee Payment Date and shall be
     nonrefundable.

          (ii) In addition to the foregoing fees and commissions, the Borrower
     shall pay or reimburse each Issuing Bank for such normal and customary
     costs and reasonable expenses as are incurred or charged by such Issuing
     Bank in issuing, effecting payment under, amending or otherwise
     administering any Letter of Credit.

          (iii) The Administrative Agent shall, promptly following its receipt
     thereof, distribute to the relevant Issuing Bank and the L/C Participants
     all fees and commissions received by the Administrative Agent for their
     respective accounts pursuant to this Section 2.4(c).

     (d) L/C Participations.

          (i) Each Issuing Bank irrevocably agrees to grant and hereby grants to
     each L/C Participant, and, to induce each Issuing Bank to issue Letters of
     Credit hereunder, each L/C Participant irrevocably agrees to accept and
     purchase and hereby accepts and purchases from such Issuing Bank, on the
     terms and conditions hereinafter stated, for such L/C Participant's own
     account and risk an undivided interest equal to such L/C Participant's
     Revolving Percentage in each Issuing Bank's obligations and rights under
     each Letter of Credit issued hereunder and the aggregate amount of drawings
     under Letters of Credit that have not then been reimbursed pursuant to
     Section 2.4(e). Each L/C Participant unconditionally and irrevocably agrees
     with each Issuing Bank that, if a


                                       25

<PAGE>

     draft is paid under any Letter of Credit for which such Issuing Bank is not
     reimbursed in full by the Borrower in accordance with the terms of this
     Agreement, such L/C Participant shall pay to such Issuing Bank upon demand
     at such Issuing Bank's address for notices specified herein an amount equal
     to such L/C Participant's Revolving Percentage of the amount of such draft,
     or any part thereof, which is not so reimbursed. Each Bank acknowledges and
     agrees that its obligation to acquire participations pursuant to this
     Section 2.4(d)(i) in respect of Letters of Credit is absolute and
     unconditional and shall not be affected by any circumstance whatsoever,
     including any amendment, renewal or extension of any Letter of Credit or
     the occurrence and continuance of a Default or reduction or termination of
     the Commitments, and that each such payment shall be made without any
     offset, abatement, withholding or reduction whatsoever.

          (ii) If any amount required to be paid by any L/C Participant to an
     Issuing Bank pursuant to Section 2.4(d)(i) in respect of any unreimbursed
     portion of any payment made by such Issuing Bank under any Letter of Credit
     is not paid to such Issuing Bank within one Business Day after the date
     such payment is due, such L/C Participant shall pay to such Issuing Bank on
     demand an amount equal to the product of (A) such amount, times (B) the
     daily average Federal Funds Effective Rate as quoted by the relevant
     Issuing Bank, during the period from and including the date such payment is
     required to the date on which such payment is immediately available to such
     Issuing Bank, times (C) a fraction the numerator of which is the number of
     days that elapse during such period and the denominator of which is 360. If
     any such amount required to be paid by any L/C Participant pursuant to
     Section 2.4(d)(i) is not in fact made available to the relevant Issuing
     Bank by such L/C Participant within three (3) Business Days after the date
     such payment is due, such Issuing Bank shall be entitled to recover from
     such L/C Participant, on demand, such amount with interest thereon
     calculated from such due date at the ABR. A certificate of the relevant
     Issuing Bank submitted to any L/C Participant with respect to any amounts
     owing under this subsection shall be conclusive in the absence of manifest
     error.

          (iii) Whenever, at any time after any Issuing Bank has made payment
     under any Letter of Credit and has received from any L/C Participant its
     pro rata share of such payment in accordance with Section 2.4(d)(i), such
     Issuing Bank receives any payment related to such Letter of Credit (whether
     directly from the Borrower or otherwise, including proceeds of collateral
     applied thereto by the Issuing Bank), or any payment of interest on account
     thereof, such Issuing Bank will distribute to such L/C Participant its pro
     rata share thereof; provided, however, that in the event that any such
     payment received by such Issuing Bank shall be required to be returned by
     such Issuing Bank, such L/C Participant shall return to such Issuing Bank
     the portion thereof previously distributed by such Issuing Bank to it.

     (e) Reimbursement Obligation of the Borrower. (i) The Borrower shall
reimburse each Issuing Bank for any payment that such Issuing Bank makes under a
Letter of Credit on or before the date of such payment if the Borrower receives
notice of such payment on or before 10:00 a.m. (New York City time) on the date
such payment is made by such Issuing Bank; provided, however, that, if the
Borrower does not receive timely notice or reimburse such Issuing Bank under
this Section 2.4(e)(i), then Section 2.4(e)(ii) shall apply. Each such payment
shall be


                                       26
<PAGE>

made to the relevant Issuing Bank at its address for notices specified herein in
Dollars and in immediately available funds.

          (ii) Notwithstanding Section 5.2, each drawing under any Letter of
     Credit shall be deemed to constitute a Borrowing of ABR Loans in the amount
     of such drawing unless the Borrower has reimbursed the relevant Issuing
     Bank under Section 2.4(e)(i). The Borrowing Date with respect to each such
     borrowing shall be deemed to be the date of such drawing.

     (f) Obligations Absolute.

          (i) The Borrower's payment obligations under Section 2.4(e) shall be
     absolute and unconditional under any and all circumstances and irrespective
     of any set-off, counterclaim or defense to payment that the Borrower may
     have or have had against the relevant Issuing Bank or any beneficiary of a
     Letter of Credit other than a defense based upon the gross negligence or
     willful misconduct of such Issuing Bank or violation of the standards of
     care specified in the Uniform Commercial Code of the State of New York.

          (ii) The Borrower also agrees with each Issuing Bank that no Issuing
     Bank shall be responsible for, and the Borrower's Reimbursement Obligations
     under Section 2.4(e) shall not be affected by, among other things, (i) the
     validity or genuineness of documents or of any endorsements thereon, even
     though such documents shall in fact prove to be invalid, fraudulent or
     forged, (ii) any dispute between or among the Borrower and any beneficiary
     of any Letter of Credit or any other party to which such Letter of Credit
     may be transferred or (iii) any claims whatsoever of the Borrower against
     any beneficiary of such Letter of Credit or any such transferee.

          (iii) No Issuing Bank shall be liable for any error, omission,
     interruption or delay in transmission, dispatch or delivery of any message
     or advice, however transmitted, in connection with any Letter of Credit,
     except for errors or omissions caused by such Issuing Bank's gross
     negligence or willful misconduct or in violation of the standards of care
     specified in the Uniform Commercial Code of the State of New York.

          (iv) The Borrower agrees that any action taken or omitted by any
     Issuing Bank under or in connection with any Letter of Credit or the
     related drafts or documents, if done in the absence of gross negligence or
     willful misconduct and in accordance with the standards of care specified
     in the Uniform Commercial Code of the State of New York, shall be binding
     on the Borrower and shall not result in any liability of such Issuing Bank
     to the Borrower.

     (g) Letter of Credit Payments. If any draft shall be presented for payment
under any Letter of Credit, the relevant Issuing Bank shall promptly notify the
Borrower by telephone (confirmed in writing) of the date and amount thereof and
whether such Issuing Bank has made or will make a payment thereunder. The
responsibility of such Issuing Bank to the Borrower in connection with any draft
presented for payment under any Letter of Credit shall, in addition to


                                       27

<PAGE>

any payment obligation expressly provided for in such Letter of Credit, be
limited to determining that the documents (including each draft) delivered under
such Letter of Credit in connection with such presentment are in conformity with
such Letter of Credit.

     (h) Application. To the extent that any provision of any Application
related to any Letter of Credit is inconsistent with the provisions of this
Section 2.4, the provisions of this Section 2.4 shall control.

     (i) Replacement of the Issuing Bank. Any Issuing Bank may be replaced at
any time by written agreement among the Borrower, the Administrative Agent, the
replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent
shall notify the Banks of any such replacement of such Issuing Bank. At the time
any such replacement shall become effective, the Borrower shall pay all unpaid
fees accrued for the account of such replaced Issuing Bank pursuant to Section
2.4(c). From and after the effective date of any such replacement, (i) the
applicable successor Issuing Bank shall have all the rights and obligations of
such Issuing Bank under this Agreement with respect to Letters of Credit to be
issued thereafter and (ii) references herein to the term "Issuing Bank" shall be
deemed to refer to such successor or to any previous Issuing Bank, or to such
successor and all previous Issuing Banks, as the context shall require. After
the replacement of an Issuing Bank hereunder, the applicable replaced Issuing
Bank shall remain a party hereto and shall continue to have all the rights and
obligations of an Issuing Bank under this Agreement with respect to Letters of
Credit issued by it prior to such replacement, but shall not be required to
issue additional Letters of Credit.

     SECTION 2.5. Increase in the Aggregate Commitments. (a) The Borrower may,
at any time but in any event not more than twice in any calendar year prior to
the Termination Date, whether or not the Commitments have been reduced pursuant
to Section 4.5, by notice to the Administrative Agent, request that the
aggregate amount of the Commitments be increased by an amount of $10,000,000 or
an integral multiple of $5,000,000 in excess thereof (a "Commitment Increase")
to be effective as of a date that is at least 90 days prior to the scheduled
Termination Date then in effect (the "Increase Date") as specified in the
related notice to the Administrative Agent; provided, however, that (i) in no
event shall the aggregate amount of the Commitments at any time exceed
$400,000,000 and (ii) on the date of any request by the Borrower for a
Commitment Increase and on the related Increase Date, the applicable conditions
set forth in Section 5.2 shall be satisfied.

     (b) The Administrative Agent shall promptly notify the Banks of a request
by the Borrower for a Commitment Increase, which notice shall include (i) the
proposed amount of such requested Commitment Increase, (ii) the proposed
Increase Date and (iii) the date by which the Banks wishing to participate in
the Commitment Increase must commit to an increase in the amount of their
respective Commitments (the "Commitment Date"). Each Bank that is willing, in
its sole discretion, to participate in such requested Commitment Increase (each
an "Increasing Bank") shall give written notice to the Administrative Agent and
the Borrower on or prior to the Commitment Date of the amount by which it is
willing to increase its Commitment. If the Banks notify the Administrative Agent
and the Borrower that they are willing to increase the amount of their
respective Commitments by an aggregate amount that exceeds the amount of the
requested Commitment Increase, the requested Commitment Increase shall be
allocated among the Banks


                                       28

<PAGE>

willing to participate therein in such amounts as are agreed between the
Borrower and the Administrative Agent.

     (c) Promptly following each Commitment Date, the Administrative Agent shall
notify the Borrower as to the amount, if any, by which the Banks are willing to
participate in the requested Commitment Increase. If the aggregate amount by
which the Banks are willing to participate in any requested Commitment Increase
on any such Commitment Date is less than the requested Commitment Increase, then
the Borrower may request Banks to increase their participation and extend offers
to one or more Eligible Assignees to participate in any portion of the requested
Commitment Increase that has not been committed to by the Lenders as of the
applicable Commitment Date; provided, however, that the Revolving Commitment of
each such Eligible Assignee shall be in an amount not less than $10,000,000.

     (d) On each Increase Date, each Eligible Assignee that accepts an offer to
participate in a requested Commitment Increase in accordance with Section 2.5(b)
(each such Eligible Assignee, an "Assuming Bank") shall become a Bank party to
this Agreement as of such Increase Date and the Commitment of each Increasing
Bank for such requested Commitment Increase shall be so increased by such amount
(or by the amount allocated to such Bank pursuant to the last sentence of
Section 2.5(b)) as of such Increase Date; provided, however, that the
Administrative Agent shall have received on or before such Increase Date the
following, each dated such date:

               (i) (A) certified copies of resolutions of the Board of Directors
          of the Borrower or the Executive Committee of such Board approving the
          Commitment Increase and the corresponding modifications to this
          Agreement and (B) opinions of counsel for the Borrower (which may be
          in-house counsel), in form and substance reasonably acceptable to the
          Administrative Agent, covering the matters covered by the opinions of
          counsel delivered pursuant to Section 5.1(c);

               (ii) an assumption agreement from each Assuming Bank, if any,
          substantially in the form of Exhibit E hereto (each an "Assumption
          Agreement"), duly executed by such Eligible Assignee, the
          Administrative Agent and the Borrower; and

               (iii) confirmation from each Increasing Bank of the increase in
          the amount of its Commitment in a writing satisfactory to the Borrower
          and the Administrative Agent.

On each Increase Date, upon fulfillment of the conditions set forth in the
immediately preceding sentence of this Section 2.5(d), the Administrative Agent
shall notify the Banks (including, without limitation, each Assuming Bank) and
the Borrower, on or before 1:00 P.M. (New York City time), by telecopier, of the
occurrence of the Commitment Increase to be effected on such Increase Date and
shall record in the Register the relevant information with respect to each
Increasing Bank and each Assuming Bank on such date.

     (e) The Administrative Agent shall promptly notify the Borrower and the
Banks of any increase in the amount of the aggregate Commitments pursuant to
this Section and of the


                                       29

<PAGE>

respective adjusted Commitment and Revolving Percentage of each Bank after
giving effect thereto. The Borrower acknowledges that, in order to maintain the
Revolving Percentage of each Bank, a non-pro-rata increase in the aggregate
Commitments may require prepayment or funding of all or portions of certain
Loans on the date of such increase (and any such prepayment or funding shall be
subject to the other provisions of this Agreement). Effective upon such
increase, the amount of the participations held by each Bank in each Letter of
Credit then outstanding shall be adjusted such that, after giving effect to such
adjustments, each Bank shall hold participations in each such Letter of Credit
in accordance with the Revolving Percentage of such Bank after giving effect to
such increase.

     SECTION 2.6. Extension Option. The Borrower may request that the
Commitments be extended for additional one year periods by providing not less
than 65 days' written notice to the Administrative Agent prior to any
anniversary of the Closing Date (each, a "Noticed Anniversary Date"). If a
Lender agrees, in its individual and sole discretion, to extend its Commitment
(such Lender, an "Extending Lender"), it will notify the Administrative Agent,
in writing, of its decision to do so no later than 20 days prior to the
applicable Noticed Anniversary Date. The Administrative Agent will notify the
Borrower, in writing, of the Lenders' decisions no later than 15 days prior to
such Noticed Anniversary Date. The Extending Lenders' Commitments will be
extended for an additional year from the Termination Date (the "Extended
Termination Date") or the Extended Termination Date (the "Second Extended
Termination Date"); provided that (i) more than 50% of the Commitments is
extended or otherwise committed to by Extending Lenders and any new Lenders and
(ii) on the date of any request by the Borrower to extend the Commitments, the
applicable conditions set forth in Section 5.2 shall be satisfied. No Lender
shall be required to consent to any such extension request and any Lender that
declines or does not respond to the Borrower's request for commitment renewal (a
"Declining Lender") will have its Commitment terminated on the then existing
Termination Date (without regard to any renewals by other Lenders). The Borrower
will have the right to accept commitments from Eligible Assignees in an amount
equal to the amount of the Commitments of any Declining Lenders; provided that
the Extending Lenders will have the right to increase their Commitments up to
the amount of the Declining Lenders' Commitments before the Borrower will be
permitted to substitute any Eligible Assignees for the Declining Lenders. The
Borrower may only extend the Termination Date twice during the term of this
Agreement pursuant to this Section 2.6.

                                   ARTICLE III

                        PROVISIONS RELATING TO ALL LOANS

     SECTION 3.1. Evidence of Loans. (a) Each Bank shall maintain in accordance
with its usual practice an account or accounts evidencing indebtedness of the
Borrower to such Bank resulting from each Loan made by such Bank from time to
time, including, without limitation, the amounts of principal and interest
payable and paid to such Bank from time to time under this Agreement.

     (b) The Administrative Agent shall maintain the Register pursuant to
Section 10.6(d) and a subaccount therein for each Bank, in which shall be
recorded (i) the amount of each Loan made by each Bank through the
Administrative Agent hereunder, the type thereof and each Interest Period
applicable thereto, (ii) the amount of any principal or interest due and payable
or


                                       30

<PAGE>

to become due and payable from the Borrower to each Bank hereunder and (iii)
both the amount of any sum received by the Administrative Agent hereunder from
the Borrower and each Bank's share thereof.

     (c) The entries made in the Register and the accounts of each Bank
maintained pursuant to Section 3.1(a) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amount of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Bank or the Administrative Agent to maintain the Register or any
such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans
actually made to the Borrower by such Bank in accordance with the terms of this
Agreement.

     SECTION 3.2. Fees. (a) The Borrower agrees to pay to the Administrative
Agent for the account of each Bank the Commitment Fee, from the date hereof
until such date that the Loans and other obligations under this Agreement have
been paid in full, payable quarterly in arrears on the last day of each March,
June, September and December until such date that the Loans and other
obligations under this Agreement have been paid in full and on such date of
payment in full, commencing on June 30, 2006.

     (b) The Borrower agrees to pay to the Administrative Agent for the account
of each Bank the applicable Utilization Fee on the Outstanding Extensions of
Credit of such Bank at any time that the Total Outstanding Extensions of Credit
outstanding shall exceed 50% of the Total Commitments then in effect, payable
quarterly in arrears on the last day of each March, June, September and
December, commencing on June 30, 2006.

     (c) The fees payable under Sections 3.2(a) and 3.2(b) shall be calculated
by the Administrative Agent on the basis of a 365- or 366-day year, as the case
may be, for the actual days (including the first day but excluding the last day)
occurring in the period for which such fee is payable.

     (d) The Borrower shall pay to the Administrative Agent, for its own
account, the fees in the amounts and on the dates previously agreed to in
writing by the Borrower and the Administrative Agent.

     SECTION 3.3. Interest. The Borrower shall pay interest on the unpaid
principal amount of each Loan made by each Bank from the date of such Loan until
such principal amount shall be paid in full, at the times and at the rates per
annum set forth below:

     (a) ABR Loans. Each ABR Loan shall bear interest at a rate per annum equal
at all times to the lesser of (i) the ABR plus the Applicable Margin and (ii)
the Highest Lawful Rate, payable quarterly in arrears on the last day of each
March, June, September and December and on the Termination Date.

     (b) LIBOR Rate Loans. Each LIBOR Rate Loan shall bear interest at a rate
per annum equal at all times to, in the case of each LIBOR Rate Loan, the lesser
of (A) the sum of the LIBOR Rate for the applicable Interest Period for such
Loan plus the Applicable Margin and (B) the Highest Lawful Rate, payable on the
last day of such Interest Period and, with respect to Interest Periods of six
months or longer, on the ninetieth (90th) day after the commencement of


                                       31

<PAGE>

the Interest Period and on each succeeding ninetieth (90th) day during such
Interest Period, and on the Termination Date.

     (c) Calculations. Interest that is determined by reference to the ABR shall
be calculated by the Administrative Agent on the basis of a 365- or 366-day
year, as the case may be, for the actual days (including the first day but
excluding the last day) occurring in the period in which such interest is
payable and otherwise shall be calculated by the Administrative Agent on the
basis of a 360-day year for the actual days (including the first day and
excluding the last day) occurring in the period for which such interest is
payable.

     (d) Default Rate. Notwithstanding the foregoing, if all or a portion of (i)
the principal amount of any Loan or Reimbursement Obligation, (ii) any interest
payable thereon, or (iii) any Commitment Fee, Utilization Fee or other amount
payable hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue amount shall bear interest, payable
from time to time on demand, at a rate per annum equal to the lesser of (A) the
Highest Lawful Rate and (B) the Default Rate, in each case from the date of such
non-payment until such amount is paid in full (as well after as before
judgment).

     (e) Determination Conclusive. Each determination of an interest rate by the
Administrative Agent pursuant to any provisions of this Agreement shall be
conclusive and binding on the Borrower and the Banks in the absence of manifest
error. The Administrative Agent shall, at the request of the Borrower, deliver
to the Borrower a statement showing in reasonable detail the quotations used by
the Administrative Agent in determining the LIBOR Rate.

     SECTION 3.4. Reserve Requirements. (a) The Borrower agrees to pay to each
Bank that requests compensation under this Section 3.4 in accordance with the
provisions set forth in Section 4.8(b), so long as such Bank shall be required
to maintain reserves against "Eurocurrency liabilities" under Regulation D of
the Board (or, so long as such Bank shall be required by the Board or by any
other Governmental Authority to maintain reserves against any other category of
liabilities that includes deposits by reference to which the interest rate on
LIBOR Rate Loans is determined as provided in this Agreement or against any
category of extensions of credit or other assets of such Bank that includes any
LIBOR Rate Loans), an additional amount (determined by such Bank and notified to
the Borrower pursuant to the provisions set forth in Section 4.8(b))
representing such Bank's calculation or, if an accurate calculation is
impracticable, reasonable estimate (using such method of allocation to such
Loans of the Borrower as such Bank shall determine in accordance with Section
4.8(a)) of the actual costs, if any, incurred by such Bank during the relevant
Interest Period as a result of the applicability of the foregoing reserves to
such LIBOR Rate Loans, which amount in any event shall not exceed the product of
the following for each day of such Interest Period:

          (i) the principal amount of the relevant LIBOR Rate Loans made by such
     Bank outstanding on such day;

          (ii) the difference between (A) a fraction, the numerator of which is
     the LIBOR Rate (expressed as a decimal) applicable to such LIBOR Rate Loan
     (expressed as a decimal), and the denominator of which is one minus the
     maximum rate (expressed as a


                                       32

<PAGE>

     decimal) at which such reserve requirements are imposed by the Board or
     other Governmental Authority on such date, minus (B) such numerator; and

          (iii) a fraction, the numerator of which is one and the denominator of
     which is 360.

     (b) The agreements in this Section 3.4 shall survive the termination of
this Agreement and the payment of all amounts payable hereunder; provided,
however, that in no event shall the Borrower be obligated to reimburse or
compensate any Bank for amounts contemplated by this Section 3.4 for any period
prior to the date that is 90 days before the date upon which such Bank requests
in writing such reimbursement or compensation from the Borrower.

     SECTION 3.5. Interest Rate Determination and Protection. (a) The rate of
interest for each LIBOR Rate Loan shall be determined by the Administrative
Agent two Business Days before the first day of each Interest Period applicable
to such Loan. The Administrative Agent shall give prompt notice to the Borrower
and the Banks of the applicable interest rate determined by the Administrative
Agent for purposes of Sections 3.3(a) and (b) hereof.

     (b) If, with respect to any LIBOR Rate Loans, prior to the first day of an
Interest Period (i) the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the London interbank market, adequate and reasonable
means do not exist for ascertaining the LIBOR Rate for such Interest Period or
(ii) the Administrative Agent shall have received notice from the Majority Banks
that the LIBOR Rate determined or to be determined for such Interest Period will
not adequately and fairly reflect the cost to such Banks (as determined in good
faith and certified by such Banks) of making or maintaining their affected LIBOR
Rate Loans during such Interest Period, the Administrative Agent shall give
facsimile or telephonic notice thereof (with written notice to follow promptly)
to the Borrower and the Banks as soon as practicable thereafter. If such notice
is given, (A) any LIBOR Rate Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (B) any Loans that were to have been
converted on the first day of such Interest Period to LIBOR Rate Loans shall be
continued as ABR Loans and (C) any outstanding LIBOR Rate Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. Until such
notice has been withdrawn by the Administrative Agent, no further LIBOR Rate
Loans shall be made or continued as such, nor shall the Borrower have the right
to convert Loans to LIBOR Rate Loans.

     SECTION 3.6. Voluntary Interest Conversion or Continuation of Loans. (a)The
Borrower may on any Business Day, upon the Borrower's irrevocable oral or
written notice of interest conversion/continuation given by the Borrower to the
Administrative Agent not later than 11:00 A.M. (New York City time) on the third
Business Day prior to the date of the proposed interest conversion or
continuation in the case of a LIBOR Rate Loan, (i) convert Loans of one Type
into Loans of another Type; (ii) convert LIBOR Rate Loans for a specified
Interest Period into LIBOR Rate Loans for a different Interest Period; or (iii)
continue LIBOR Rate Loans for a specified Interest Period as LIBOR Rate Loans
for the same Interest Period; provided, however, that (A) any conversion of any
LIBOR Rate Loans into LIBOR Rate Loans for a different Interest Period, or into
ABR Loans, or any continuation of LIBOR Rate Loans for the same Interest Period
shall be made on, and only on, the last day of an Interest Period for such


                                       33

<PAGE>

LIBOR Rate Loans; (B) no Loan may be converted into or continued as a LIBOR Rate
Loan by the Borrower so long as an Event of Default has occurred and is
continuing, and (C) no Loan may be converted into or continued as a LIBOR Rate
Loan if after giving effect thereto, Section 2.3 would be contravened. With
respect to any oral notice of interest conversion/continuation given by the
Borrower under this Section 3.6(a), the Borrower shall promptly thereafter
confirm such notice in writing. Each written notice of interest
conversion/continuation given by the Borrower under this Section 3.6(a) and each
confirmation of an oral notice of interest conversion/continuation given by the
Borrower under this Section 3.6(a) shall be in substantially the form of Exhibit
B hereto ("Notice of Interest Conversion/Continuation"). Each such Notice of
Interest Conversion/Continuation shall specify therein the requested (x) date of
such interest conversion or continuation; (y) the Loans to be converted or
continued; and (z) if such interest conversion or continuation is into LIBOR
Rate Loans, the duration of the Interest Period for each such LIBOR Rate Loan.
Upon receipt of any such Notice of Interest Conversion/Continuation, the
Administrative Agent shall promptly notify each Bank thereof. Each Notice of
Interest Conversion/ Continuation shall be irrevocable and binding on the
Borrower.

     (b) If the Borrower shall fail to deliver to the Administrative Agent a
Notice of Interest Conversion/Continuation in accordance with Section 3.6(a)
hereof, or to select the duration of any Interest Period for the principal
amount outstanding under any LIBOR Rate Loan by 11:00 A.M. (New York City time)
on the third Business Day prior to the last day of the Interest Period
applicable to such Loan in accordance with Section 3.6(a), the Administrative
Agent will forthwith so notify the Borrower and the Banks (provided that the
failure to give such notice shall not affect the conversion referred to below)
and such Loans will automatically, on the last day of the then existing Interest
Period therefor, convert into LIBOR Rate Loans with a one month Interest Period.

     SECTION 3.7. Funding Losses Relating to LIBOR Rate Loans. (a) The Borrower
agrees, without duplication of any other provision under this Agreement, to
indemnify each Bank and to hold each Bank harmless from any loss or expense that
such Bank may sustain or incur as a consequence of (i) default by the Borrower
in payment when due of the principal amount of or interest on any LIBOR Rate
Loan, (ii) default by the Borrower in making a borrowing of, conversion into or
continuation of any LIBOR Rate Loan after the Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (iii)
default by the Borrower in making any prepayment after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (iv) the
making of a prepayment of LIBOR Rate Loans or the conversion of LIBOR Rate Loans
into ABR Loans, on a day that is not the last day of an Interest Period with
respect thereto (excluding any prepayment made pursuant to Section 3.8) on a day
that is not the scheduled maturity date with respect thereto, including, without
limitation, in each case, any such loss or expense arising from the reemployment
of funds obtained by it or from fees payable to terminate the deposits from
which such funds were obtained. The calculation of all amounts payable to a Bank
under this Section 3.7(a) shall be made pursuant to the method described in
Section 4.8(a), but in no event shall such amounts payable with respect to any
LIBOR Rate Loan exceed the amounts that would have been payable assuming such
Bank had actually funded its relevant LIBOR Rate Loan through the purchase of a
deposit bearing interest at the LIBOR Rate in an amount equal to the amount of
such LIBOR Rate Loan and having a maturity comparable to, with respect to any
LIBOR Rate Loan, the relevant Interest Period, provided, that each Bank may fund
each of its LIBOR Rate Loans in any manner it sees


                                       34

<PAGE>

fit, and the foregoing assumption shall be utilized only for the calculation of
amounts payable under this Section 3.7(a).

     (b) The agreements in this Section 3.7 shall survive the termination of
this Agreement and the payment of all amounts payable hereunder; provided,
however, that in no event shall the Borrower be obligated to reimburse or
compensate any Bank for amounts contemplated by this Section 3.7 for amounts
accruing prior to the date that is 90 days prior to the date upon which such
Bank requests in writing such reimbursement or compensation from the Borrower.

     SECTION 3.8. Change in Legality. (a) Notwithstanding any other provision of
this Agreement, if any Bank shall notify the Administrative Agent that it has
determined in good faith that the introduction of or any change in or in the
interpretation or application of any law or regulation by any Governmental
Authority (in each case occurring after the date of this Agreement) makes it
unlawful, or any central bank or other Governmental Authority asserts after the
date of this Agreement that it is unlawful, for any Bank or its applicable
lending office to perform its obligations hereunder to make LIBOR Rate Loans or
to fund or maintain LIBOR Rate Loans hereunder, (i) the obligation of such Bank
to make, or to convert Loans into, or to continue LIBOR Rate Loans as, LIBOR
Rate Loans shall be suspended until the Administrative Agent shall notify the
Borrower that the circumstances causing such suspension no longer exist; (ii)
the Borrower shall, at its option, either prepay in full all LIBOR Rate Loans of
such Bank then outstanding, or convert all such Loans to ABR Loans, on the
respective last days of the then current Interest Periods with respect to such
Loans (or within such earlier period as required by law), accompanied, in the
case of any prepayments, by interest accrued thereon and any amounts payable
under Section 3.7(a). Each Bank agrees that it will use reasonable efforts to
designate a different lending office for the LIBOR Rate Loans due to it affected
by this Section 3.8, if such designation will avoid the illegality described in
this Section 3.8 so long as such designation will not be disadvantageous to such
Bank as determined by such Bank in its sole discretion acting in good faith.

     (b) For purposes of this Section 3.8, a notice to the Borrower (with a copy
to the Administrative Agent) by any Bank pursuant to paragraph (a) above shall
be effective on the date of receipt thereof by the Borrower.

                                   ARTICLE IV

                        INCREASED COSTS, TAXES, PAYMENTS

                                 AND PREPAYMENTS

     SECTION 4.1. Increased Costs; Capital Adequacy. (a) If after the date of
this Agreement the adoption of or any change in any law or regulation or in the
interpretation or application thereof by any Governmental Authority or
application thereof or compliance by any Bank with any request or directive
(whether or not having the force of law) from any central bank or other
Governmental Authority made subsequent to the date of this Agreement:

          (i) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities


                                       35

<PAGE>

     in or for the account of, advances, loans or other extensions of credit by,
     or any other acquisition of funds by, any office of such Bank that is not
     otherwise included in the determination of the LIBOR Rate hereunder (except
     for amounts covered by Section 3.4 or any other Section hereof); or

          (ii) shall impose on such Bank any other condition;

and the result of any of the foregoing is to increase the actual cost to such
Bank, by an amount that such Bank deems to be material, of making, converting
into, continuing or maintaining LIBOR Rate Loans or issuing or participating in
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Bank, upon
its demand in the manner set forth in Section 4.8(b), any additional amounts,
computed by such Bank in accordance with Section 4.8(a), necessary to compensate
such Bank for such actual increased cost or reduced amount receivable that is
attributable to Loans or Commitments (to the extent that such Bank has not
already been compensated or reimbursed for such amounts pursuant to any other
provision of this Agreement). If any Bank becomes entitled to claim any
additional amounts pursuant to this Section 4.1(a) from the Borrower, it shall
promptly notify the Borrower, through the Administrative Agent, of the event by
reason of which it has become so entitled in the manner set forth in Section
4.8(b).

     (b) If any Bank determines in good faith that the introduction of or any
change in or in the interpretation or application by any Governmental Authority
of any law or regulation regarding capital adequacy after the date of this
Agreement or compliance by such Bank or any corporation controlling such Bank
with any law or regulation or any guideline or request from any central bank or
other Governmental Authority (whether or not having the force of law) made or
issued after the date of this Agreement does or shall have the effect, as a
result of such Bank's obligations under this Agreement or under any Letter of
Credit, of reducing the rate of return on such Bank's or such corporation's
capital to a level below that which such Bank or such corporation could have
achieved but for such change or compliance (taking into consideration such
Bank's or such corporation's policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, the Borrower shall pay to the
Administrative Agent for the account of such Bank, from time to time as
specified by such Bank in the manner set forth in Section 4.8(b), additional
amounts, computed by such Bank in accordance with Section 4.8(a), sufficient to
compensate such Bank or such corporation in the light of such circumstances, to
the extent that such Bank reasonably determines such reduction in rate of return
is allocable to the existence of such Bank's obligations hereunder.

     (c) The agreements contained in this Section 4.1 shall survive the
termination of this Agreement and the payment of all amounts payable hereunder;
provided, however, that in no event shall the Borrower be obligated to reimburse
or compensate any Bank for amounts contemplated by this Section 4.1 for any
period prior to the date that is 90 days prior to the date upon which such Bank
requests in writing such reimbursement or compensation from the Borrower.

     SECTION 4.2. Pro Rata Treatment and Payments and Computations. (a) Each
Borrowing of Loans by the Borrower from the Banks hereunder, each payment by the
Borrower on account of any commitment or other fee, any reduction of the
Commitments of the Banks and


                                       36

<PAGE>

any prepayment on account of principal and interest on the Loans shall be made
pro rata according to the respective Revolving Percentages of the Banks.

     (b) The Borrower shall make each payment (including each prepayment)
hereunder, whether on account of principal, interest, fees or otherwise, without
setoff or counterclaim, not later than 12:00 Noon (New York City time) on the
day when due in Dollars to the Administrative Agent at the Funding Office in
immediately available funds. The Administrative Agent will promptly thereafter
cause to be distributed like funds relating to the payment of principal,
interest, Letter of Credit fees or commitment or other fees (to the extent
received by the Administrative Agent) ratably to the Banks according to the
amounts of their respective Loans, L/C Obligations and Commitments in respect of
which such payment is made, and like funds relating to the payment of any other
amount payable to any Bank (to the extent received by the Administrative Agent)
to such Bank, in each case to be applied in accordance with the terms of this
Agreement.

     (c) Whenever any payment hereunder or under the Notes shall be stated to be
due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be;
provided, however, if such extension would cause payment of interest on or
principal of LIBOR Rate Loans to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (d) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Banks hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Bank on such due date an amount
equal to the amount then due such Bank. If and to the extent the Borrower shall
not have so made such payment in full to the Administrative Agent, each Bank
shall pay to the Administrative Agent on demand an amount equal to the product
of (i) the daily average Federal Funds Effective Rate during such period, times
(ii) the amount of such Bank's Revolving Percentage of such payment, times (iii)
a fraction, the numerator of which is the number of days that elapse from and
including the date such amount is distributed to such Bank to the date on which
such Bank's Revolving Percentage of such payment shall have become immediately
available to the Administrative Agent and the denominator of which is 360.

     SECTION 4.3. Taxes. (a) Any and all payments by the Borrower hereunder or
under the Loan Documents shall be made free and clear of and without deduction
or withholding for or on account of any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Bank and the Administrative Agent, net
income taxes, branch profits taxes and franchise taxes imposed on it as a result
of a present or former connection between the jurisdiction (or political
subdivision thereof) of the government or taxing authority imposing such tax and
the Administrative Agent or such Bank other than a connection arising solely
from the Administrative Agent or such Bank having executed, delivered or
performed its obligations or received a payment under, or enforced, this
Agreement or any Note (all such non-excluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as "Taxes").
If the Borrower


                                       37

<PAGE>

shall be required by law to deduct any Taxes from or in respect of any sum
payable hereunder or under any Note to any Bank or the Administrative Agent, (i)
the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 4.3) such Bank or the Administrative Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made; (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law; provided, however, that
the Borrower shall not be required to increase any such sums payable to any Bank
with respect to any Taxes (i) that are attributable to such Bank's failure to
comply with the requirements of Section 4.3(d) or (ii) that are United States
withholding taxes imposed on sums payable to such Bank at the time such Bank
becomes a party to this Agreement (or maintains a lending office), except to the
extent that any such Bank's assignor (if any) was entitled, at the time of
assignment, to receive additional amounts from the Borrower with respect to such
Taxes pursuant to this Section 4.3. Whenever any Taxes or Other Taxes (as
defined in Section 4.3(b)) are payable by the Borrower, as promptly as possible
thereafter the Borrower shall send to the Administrative Agent for the account
of the relevant Bank or Administrative Agent, as the case may be, either (A)
official tax receipts or notarized copies of such receipts to such Bank within
thirty (30) days after payment of any applicable tax or (B) a certificate
executed by a Responsible Officer of the Borrower confirming that such Taxes or
Other Taxes have been paid, together with evidence of such payment.

     (b) In addition, the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or under any Note or from the
execution, delivery or registration of or otherwise with respect to, this
Agreement, any other Loan Document, or the Loans and for which such Bank or the
Administrative Agent (as the case may be) has not been otherwise reimbursed by
the Borrower under this Agreement (hereinafter referred to as "Other Taxes").

     (c) The Borrower will indemnify each Bank and the Administrative Agent for
the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 4.3) paid by such Bank or the Administrative Agent (as the case may be)
and any liability (including penalties, interest and expenses) arising therefrom
or with respect thereto, including, without limitation or duplication, any
incremental taxes, interest or penalties that may become payable by the
Administrative Agent or any Bank as a result of any failure by the Borrower to
pay any Taxes or Other Taxes when due to the appropriate taxing authority or to
remit to any Bank the receipts or other evidence of payment of Taxes or Other
Taxes.

     (d) Each Bank registered in the Register that is not a U.S. Person as
defined in Section 7701(a)(30) of the Code agrees that it will deliver to the
Borrower and the Administrative Agent on the date hereof, or on the date which
it becomes a party to this Agreement, two duly completed copies of United States
Internal Revenue Service Form W-8BEN, W-8ECI W-8EXP or W-8IMY (or other
appropriate corresponding form) or any successor applicable form, as the case
may be. Each such Bank also agrees to deliver to the Borrower and the
Administrative Agent two further copies of the said Form W-8BEN, W-8ECI, W-8EXP,
or W-8IMY or successor applicable forms or other manner of certification, as the
case may be, on or before the date that any such form expires or becomes
obsolete or after the


                                       38

<PAGE>

occurrence of any event requiring a change in the most recent form or
certification previously delivered by it to the Borrower, and such extensions or
renewals thereof as may reasonably be requested by the Borrower or the
Administrative Agent, unless in any such case an event (including, without
limitation, any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required that renders all
such forms inapplicable or that would prevent such Bank from duly completing and
delivering any such form with respect to it and such Bank so advises the
Borrower and the Administrative Agent. Each such Bank shall certify in the case
of a Form W-8BEN, W-8ECI, W-8EXP, or W-8IMY that it is entitled to receive
payments under this Agreement without deduction or withholding of any United
States federal income taxes, subject to notification to the Borrower otherwise
pursuant to this Section 4.3(d). In the event that any such Bank fails to
deliver any forms required under this Section 4.3(d), the Borrower's obligation
to pay additional amounts shall be reduced to the amount that it would have been
obligated to pay had such forms been provided.

     (e) If any Taxes or Other Taxes are not correctly or legally asserted and
the Administrative Agent or any Bank determines, in its reasonable discretion,
that it has received a refund of those Taxes or Other Taxes as to which it has
been indemnified by the Borrower, the Administrative Agent or such Bank shall
within 20 days after such refund pay to the Borrower the amount of such refund
to the extent that the Borrower indemnified the Administrative Agent or such
Bank for such Taxes or Other Taxes pursuant to this Section 4.3, net of any
out-of-pocket costs of the Administrative Agent or such Bank and without
interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund); provided, that the Borrower, upon the request of
the Administrative Agent or such Bank, agrees to repay the amount paid over to
the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Bank in the
event the Administrative Agent or such Bank is required to repay such refund to
such Governmental Authority. This paragraph shall not be construed to require
the Administrative Agent or any Bank to make available its tax returns (or any
other information relating to its taxes which it deems confidential) to the
Borrower or any other Person.

     (f) The agreements in this Section 4.3 shall survive the termination of
this Agreement and the payment of all amounts payable hereunder; provided,
however, that (i) in no event shall the Borrower be obligated to reimburse or
compensate any Bank for amounts contemplated by this Section 4.3 for any period
before the date that is 120 days before the date upon which such Bank requests
in writing such reimbursement or compensation from the Borrower (other than any
amounts as to which the ultimate amount of the reimbursement due could not then
be determined) and (ii) nothing contained in this Section 4.3 shall require the
Borrower to pay any amount to any Bank or the Administrative Agent in addition
to that for which it has already reimbursed any Bank or the Administrative Agent
under any other provision of this Agreement.

     SECTION 4.4. Sharing of Payments, Etc. If any Bank (a "Benefitted Bank")
shall at any time receive any payment (other than pursuant to Section 2.6, 3.4,
3.7, 4.1 or 4.3) of all or part of its Loans, Reimbursement Obligations owing to
it or interest thereon, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by setoff, pursuant to events or proceedings of
the nature referred to in Section 8.1(g) or 8.1(h), or otherwise), in a greater
proportion than any such payment to or collateral received by any other Bank, if
any, in respect of such other Bank's Loans, Reimbursement Obligations owing to
it, respectively, or interest


                                       39

<PAGE>

thereon, such benefitted Bank shall purchase for cash from the other Banks a
participating interest in such portion of each such other Bank's Loans or
Reimbursement Obligations owing to it, respectively, or shall provide such other
Banks with the benefits of any such collateral, or the proceeds thereof, as
shall be necessary to cause such benefitted Bank to share the excess payment or
benefits of such collateral or proceeds ratably with each of the Banks;
provided, however, that if all or any portion of such excess payment or benefits
is thereafter recovered from such benefitted Bank, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest. The Borrower agrees that any Bank so purchasing
a participation from another Bank pursuant to this Section 4.4 may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of setoff) with respect to such participation as fully as if such Bank
were the direct creditor of the Borrower in the amount of such participation.

     SECTION 4.5. Optional Termination or Reduction of the Commitments. (a)
Unless previously terminated, the Commitments of the Banks to make Loans shall
terminate on the Termination Date.

     (b) The Borrower shall have the right, without penalty or premium, upon at
least three (3) Business Days' irrevocable written notice to the Administrative
Agent (which shall give prompt notice to each Bank), to terminate in whole the
Commitments or permanently, from time to time, to reduce ratably in part the
unused portion of the Commitments, provided that (i) each partial reduction
shall be in the aggregate principal amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof and (ii) no such termination or reduction shall
be permitted if, after giving effect thereto and to any prepayments made under
Section 4.6 by the Borrower on the effective date thereof, the Total Outstanding
Extensions of Credit then outstanding would exceed the Total Commitments then in
effect.

          Each reduction of Commitments pursuant to this Section 4.5 shall be
applied pro rata to the Commitments of each Bank. If at any time, including
after giving effect to any reduction of Commitments pursuant to this Section
4.5, the Total Outstanding Extensions of Credit exceed the Total Commitments,
the Borrower shall be obligated, first, to prepay the Loans in the amount of
such excess, second, to cash collateralize Letters of Credit to the extent that
the aggregate amount of the L/C Obligations exceeds such Total Commitments after
prepayment of all Loans.

     SECTION 4.6. Voluntary Prepayments. The Borrower may, upon written notice
delivered to the Administrative Agent not later than 11:00 A.M. (New York City
time) on the same day (or in the case of LIBOR Rate Loans, two (2) Business Days
(or such shorter or no notice as may be satisfactory to the Administrative
Agent)) before the date of prepayment stating the aggregate principal amount of
the prepayment and the Loans to be prepaid, prepay the outstanding principal
amounts of such Loans comprising part of the same Borrowing in whole or ratably
in part, together with accrued interest to the date of such prepayment on the
principal amount prepaid; provided, however, that losses incurred by any Bank
under Section 3.7 shall be payable with respect to each such prepayment in the
manner set forth in Section 3.7. Any such notice provided pursuant to this
Section 4.6 shall be irrevocable, and the payment amount specified in such
notice shall be due and payable on the prepayment date described in such notice,
together with accrued and unpaid interest on the amount prepaid. Partial
prepayments


                                       40

<PAGE>

pursuant to this Section 4.6 with respect to any Tranche of LIBOR Rate Loans
shall be in an aggregate principal amount equal to the lesser of (a) $5,000,000
or an integral multiple of $1,000,000 in excess thereof and (b) the aggregate
principal amount of such Tranche of LIBOR Rate Loans then outstanding, as the
case may be; provided that no partial prepayment of any Tranche of LIBOR Rate
Loans may be made if, after giving effect thereto, Section 2.3 would be
contravened. Partial prepayments with respect to the ABR Loans shall be made in
an aggregate principal amount equal to the lesser of (i) $5,000,000 or an
integral multiple of $1,000,000 in excess thereof or (ii) the aggregate
principal amount of ABR Loans then outstanding, as the case may be.

     SECTION 4.7. Mitigation of Losses and Costs. Any Bank claiming
reimbursement from the Borrower under any of Sections 3.4, 3.7, 4.1 and 4.3
hereof shall use reasonable efforts (including, without limitation, if requested
by the Borrower, reasonable efforts to designate a different lending office of
such Bank) to mitigate the amount of such losses, costs, expenses and
liabilities, if such efforts can be made and such mitigation can be accomplished
without such Bank suffering (i) any economic disadvantage for which such Bank
does not receive full indemnity from the Borrower under this Agreement or (ii)
any legal or regulatory disadvantage.

     SECTION 4.8. Determination and Notice of Additional Costs and Other
Amounts. (a)In determining the amount of any claim for reimbursement or
compensation under Sections 3.4, 3.7 and 4.1, each Bank may use any reasonable
averaging, attribution and allocation methods consistent with such methods
customarily employed by such Bank in similar situations.

     (b) Each Bank or, with respect to compensation claimed by it pursuant to
Section 4.3, the Administrative Agent, as the case may be, will (i) use its best
efforts to notify the Borrower through the Administrative Agent (in the case of
each Bank) of any event occurring after the date of this Agreement promptly
after the occurrence thereof and (ii) notify the Borrower through the
Administrative Agent (in the case of each Bank) promptly after such Bank or the
Administrative Agent, as the case may be, becomes aware of any event occurring
after the date of this Agreement, in either case if such event (for purposes of
this Section 4.8(b), a "Triggering Event") will entitle such Bank or the
Administrative Agent, as the case may be, to compensation pursuant to Section
3.4, 3.7, 4.1 or 4.3, as the case may be. Each such notification of a Triggering
Event shall be accompanied by a certificate of such Bank or the Administrative
Agent, as the case may be, setting forth the calculations and justification in
reasonable detail such amount or amounts as shall be necessary to compensate
such Bank or the Administrative Agent, as the case may be, as specified in
Section 3.4, 3.7, 4.1 or 4.3, as the case may be, and certifying that such costs
are generally being charged by such Bank to other similarly situated borrowers
under similar credit facilities, which certificate shall be conclusive absent
manifest error. The Borrower shall pay to the Administrative Agent for the
account of such Bank or to the Administrative Agent for its own account, as the
case may be, the amount shown as due on any such certificate within ten Business
Days after its receipt of the same.

or other requisite power and authority to conduct its business, as presently
conducted.

     (b) Organizational Status of Significant Subsidiaries of the Borrower. Each
Significant Subsidiary of the Borrower (i) is validly organized and existing and

other jurisdiction in which the conduct of its business or the ownership or
leasing of its Property requires it to be so authorized or qualified to do
business, except where the failure to be so validly organized and existing or
duly authorized or qualified or in good standing, individually or in the
aggregate, would not have a Material Adverse Effect and (ii) has the corporate,
partnership or other requisite power and authority to conduct its business, as
presently conducted, except where the failure to have such power and authority,
individually or in the aggregate, would not have a Material Adverse Effect.

     (c) Organizational Powers. The Borrower has the corporate or other
requisite power to execute, deliver and perform and comply with its obligations
under this Agreement, any Notes and the other Loan Documents to which it is a
party. This Agreement has been, and each other Loan Document to which the

Borrower.

     (d) Authorization, No Conflict, Etc. The borrowings by the Borrower

<PAGE>

the Borrower or any Significant Subsidiary of the Borrower is subject of any
court or other Governmental Authority, or the articles of incorporation or
bylaws or other organizational documents (each as amended from time to time) of
the Borrower or any Significant Subsidiary of the Borrower; (ii) violate,

time or both, or any other condition) a default under, any indenture, loan
agreement or other agreement to which the Borrower or any Restricted Subsidiary
of the Borrower is a party or by which the Borrower or any Restricted Subsidiary
of the Borrower, or any of their respective Property, is bound (except for such
violations, conflicts, breaches or defaults that, individually or in the
aggregate, do not have or would not have a Material Adverse Effect); or (iii)
result in, or require, the creation or imposition of any material Lien upon any
of the Properties of the Borrower or any Significant Subsidiary not permitted

     (f) Obligations Binding. This Agreement and the other Loan Documents to
which the Borrower is a party are the legal, valid and binding obligations of
the Borrower enforceable against the Borrower in accordance with their
respective terms (assuming due and valid authorization, execution and delivery

enforceability may be (i) limited by the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws relating to or

effect of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

     (g) Use of Proceeds, Margin Stock. The proceeds of the Loans will be used
by the Borrower (i) to support commercial paper issued by the Borrower and (ii)
for other general corporate purposes. Neither the Borrower nor any Restricted
Subsidiary of the Borrower is principally engaged in, or has as one of its
important activities, the business of extending credit for the purpose of

Subsidiary has good title to the Properties reflected in the financial
statements referred to in Section 6.1(m) and in any financial statements

financial statements and that are no longer used or useful in the conduct of the
business of the Borrower or any Significant Subsidiary or that have been
disposed of pursuant to Section 7.2(c) or (d) or that have been disposed of in
the ordinary course of their respective business, and all such Properties are
free and clear of any Lien except Liens permitted under this Agreement.


                                       45

     (i) Investment Company Act. Neither the Borrower nor any Restricted
Subsidiary of the Borrower is an "investment company" as defined in, or
otherwise subject to regulation under, the Investment Company Act of 1940, as
amended.

     (j) Material Adverse Change. Since December 31, 2005, there has been no
event, development or circumstance that, as of the Closing Date, has or would
reasonably be expected to have a Material Adverse Effect.

     (k) Litigation. As of the Closing Date, there is no litigation, action,
suit, investigation or other legal or governmental proceeding pending or, to the
best knowledge of the Borrower, threatened, at law or in equity, or before or by
any arbitrator or Governmental Authority (i) relating to the transactions under
this Agreement or under any other Loan Document or (ii) in which there is a
reasonable possibility of an adverse decision that would have a Material Adverse
Effect.

     (l) ERISA. There is no event or events, individually or in the aggregate,
that could reasonably be expected to have a Material Adverse Effect, arising out
of or in connection with (i) any Reportable Event or "accumulated funding
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) with respect to any Plan that has occurred during the five-year period
immediately preceding the date on which this representation is made or deemed
made, (ii) any failure of a Plan to comply with the applicable provisions of
ERISA and the Code, (iii) any termination of a Single Employer Plan, (iv) any
complete or partial withdrawal by the Borrower or any Commonly Controlled Entity
from any Multiemployer Plan, (v) any Lien in favor of the PBGC or any Plan that
has arisen during the five-year period referred to in clause (i) above or (vi)

     (m) Financial Statements. The consolidated financial statements of the
Borrower as of and for the twelve months ended December 31, 2005 filed with the
SEC with the Borrower's 10-K for the period then ended, copies of which have
been delivered to the Banks, present fairly in all material respects the
consolidated financial condition and results of operations of the Borrower, its
Consolidated Subsidiaries, Securitization Subsidiaries and the Unrestricted
Subsidiaries as of such date and for the period then ended, in conformity with,
as applicable, GAAP and, except as otherwise stated therein, consistently
applied (in the case of such unaudited statements, subject to year-end
adjustments and the exclusion of detailed footnotes).

     (n) Accuracy of Information. None of the documents or written information
(excluding estimates, financial projections and forecasts) provided by the
Borrower to the Banks in connection with or pursuant to this Agreement or the
other Loan Documents contains as of the date thereof or will contain as of the
date thereof any untrue statement of a material fact or omits or will omit to
state as of the date thereof a material fact (other than industry-wide risks
normally associated with the types of businesses conducted by the Borrower and
its Subsidiaries) necessary to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading, as a whole.
The estimates, financial projections and forecasts furnished to the Banks by the
Borrower with respect to the transactions contemplated under this Agreement were
prepared in good faith and on the basis of information and assumptions that the
Borrower believed to be reasonable as of the date of such information; it being
recognized by the Banks that such estimates, financial projections and forecasts
as they relate to future events are


                                       46

<PAGE>

not to be viewed as fact and that actual results during the period or periods
covered by such estimates, financial projections and forecasts may differ from
the projected results set forth therein by a material amount.

     (o) No Violation. The Borrower is not in violation of any order, writ,
injunction or decree of any court or any order, regulation or demand of any
Governmental Authority that, individually or in the aggregate, reasonably could
be expected to have a Material Adverse Effect.

     (p) Subsidiaries. Schedule 6.1(p) attached hereto sets forth each
Significant Subsidiary as of the date hereof. Except as disclosed on Schedule
6.1(p), as of the date hereof the Borrower owns, directly or indirectly through
one or more of its Subsidiaries, all of the outstanding Capital Stock of each
Significant Subsidiary, in each case free and clear of any Liens not permitted
under this Agreement.

     (q) Taxes. The Borrower and each of its Subsidiaries has filed or caused to
be filed all Federal, state and other material tax returns that are required to
be filed and has paid all taxes shown to be due and payable on said returns or
on any assessments made against it or any of its Property and all other taxes,
fees or other charges imposed on it or any of its Property by any Governmental
Authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with GAAP have been provided on the books of the Borrower
or its Subsidiaries), except where the failure to do so could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect;
no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is
being asserted, with respect to any such tax, fee or other charges (other than
any Liens or claims that could not, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect).

                       AFFIRMATIVE AND NEGATIVE COVENANTS

     SECTION 7.1. Affirmative Covenants. The Borrower covenants that, as long as
any amount is owing hereunder or under any other Loan Documents, any Letter of
Credit is outstanding or any Bank shall have any Commitment outstanding under
this Agreement:

     (a) Delivery of Financial Statements, Notices and Certificates. The
Borrower shall deliver to the Administrative Agent for distribution to the Banks
sufficient copies for each of the Banks of the following:

          (i) as soon as practicable and in any event within 90 days after the
     end of each fiscal year of the Borrower (beginning with fiscal 2006), a
     consolidated balance sheet of the Borrower, its Consolidated Subsidiaries,
     Securitization Subsidiaries and the Unrestricted Subsidiaries as of the end
     of such fiscal year and the related statements of consolidated income,
     retained earnings and cash flows prepared in conformity with GAAP
     consistently applied, setting forth in comparative form the figures for the
     previous fiscal year, together with a report thereon by independent
     certified public accountants of nationally recognized standing selected by
     the Borrower (which requirement may be


                                       47

<PAGE>

     satisfied by delivering the Borrower's Annual Report on Form 10-K with
     respect to such fiscal year as filed with the SEC);

          (ii) as soon as practicable and in any event within 55 days after the
     end of each of the first three quarters of each fiscal year of the Borrower
     (beginning with the quarter ending March 31, 2006), unaudited consolidated
     financial statements of the Borrower, its Consolidated Subsidiaries,
     Securitization Subsidiaries and the Unrestricted Subsidiaries consisting of
     at least consolidated balance sheets as at the close of such quarter and
     statements of consolidated income, retained earnings and cash flows for
     such quarter and for the period from the beginning of such fiscal year to
     the close of such quarter (which requirement may be satisfied by delivering
     the Borrower's Quarterly Report on Form 10-Q with respect to such fiscal
     quarter as filed with the SEC); such financial statements shall be
     accompanied by a certificate of a Responsible Officer of the Borrower to
     the effect that such unaudited financial statements present fairly in all
     material respects the consolidated financial condition and results of
     operations of the Borrower, its Consolidated Subsidiaries, Securitization
     Subsidiaries and the Unrestricted Subsidiaries as of such date for the
     period then ending, and have been prepared in conformity with GAAP in a
     manner consistent with the financial statements referred to in paragraph

or (b) any other transaction that is expressly permitted by the terms of any
other provision of this Agreement.

disclosure pursuant to a confidentiality agreement with third parties.

requirements or limitations on the Persons permitted to exercise such right
shall apply at any time when a Default or an Event of Default shall have
occurred and be continuing.

Subsidiaries to, maintain insurance with responsible and reputable insurance
companies or associations, or to the extent that the Borrower or such

     due and payable or (B) all Loans made hereunder, all amounts of L/C
     Obligations (whether or not the beneficiaries of the then outstanding
     Letters of Credit shall have presented the documents required for draws
     thereunder), all unpaid accrued interest or fees and any other sum payable
     under this Agreement or any other Loan Document shall become due and
     payable at any time thereafter immediately on demand by the Administrative
     Agent (acting on the instructions of the Majority Banks).

     With respect to all Letters of Credit with respect to which presentment for
honor shall not have occurred at the time of an acceleration pursuant to the
preceding paragraph or on the Termination Date, the Borrower shall at such time
deposit in a cash collateral account opened by the Administrative Agent cash or
cash equivalents in an amount equal to the aggregate then undrawn and unexpired
face amount of such Letters of Credit. The Borrower hereby grants to the
Administrative Agent, for the benefit of the Issuing Bank and the L/C
Participants, a security interest in such cash collateral to secure all
obligations of the Borrower under this Agreement and the other Loan Documents.
Interest shall accrue on such account for the benefit of the Borrower at a rate
equal to the Federal Funds Effective Rate. Amounts held in such cash collateral
account shall be applied by the Administrative Agent to the payment of drafts
drawn under such Letters of Credit, and the unused portion thereof after all
such Letters of Credit shall have expired or been fully drawn upon, if any,
shall be applied to repay other obligations of the Borrower hereunder and under
the Notes. After all such Letters of Credit shall have expired or been fully
drawn upon, all Reimbursement Obligations shall have been satisfied and all
other obligations of the Borrower hereunder and under the Notes shall have been
paid in full, the balance, if any, in such cash collateral account shall be
returned to the Borrower. The Borrower shall execute and deliver to the
Administrative Agent, for the account of each Issuing Bank and the L/C
Participants, such further documents and instruments as the Administrative Agent
may reasonably request to evidence the creation and perfection of the within
security interest in such cash collateral account.

Except as expressly provided above in this Section 8.2, presentment, demand,
protest, notice of intent to accelerate, notice of acceleration and all other
notices of any kind whatsoever are hereby expressly waived by the Borrower.

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

     SECTION 9.1. Appointment. Each Bank hereby irrevocably designates and
appoints JPMorgan Chase Bank, N.A. as the Administrative Agent of such Bank
under this Agreement and the other Loan Documents, and each such Bank
irrevocably authorizes JPMorgan Chase Bank, N.A., as the Administrative Agent
for such Bank, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Administrative Agent by the terms
of this Agreement and the other Loan Documents, together with such other powers
as are reasonably incidental thereto. Notwithstanding any provision to the
contrary elsewhere in this Agreement, (a) the Administrative Agent shall not
have any duties or responsibilities, except those expressly set forth herein, or
any fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent and (b) the other Agents and the Lead Arrangers shall not
have any duties or responsibilities hereunder, or any fiduciary relationship
with any Bank, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the other Agents or the Lead Arrangers.


                                       57
<PAGE>

     SECTION 9.2. Delegation of Duties. The Administrative Agent may execute any
of its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

     SECTION 9.3. Exculpatory Provisions. Neither any Agent nor any of their
respective officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (b) responsible in any manner to any of the Banks for any
recitals, statements, representations or warranties made by the Borrower or any
officer thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent or any other Agent under or in
connection with, this Agreement or any other Loan Document or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any Note or any other Loan Document or for any failure of the
Borrower to perform its obligations hereunder or thereunder. The Agents shall
not be under any obligation to any Bank to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Borrower.

     SECTION 9.4. Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
note, writing, resolution, notice, consent, certificate, affidavit, letter,
facsimile, telex or teletype message, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to the Borrower),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note or any loan
account in the Register as the owner thereof for all purposes unless a written
notice of assignment, negotiation or transfer thereof shall have been filed with
the Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority Banks (or, if so specified by this Agreement, all Banks) as it deems
appropriate or it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense that may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement and the other Loan Documents in accordance with a request of the
Majority Banks (or, if so specified by this Agreement, all Banks), and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Banks and all future holders of the amounts owing hereunder.

     SECTION 9.5. Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent has received notice from a
Bank or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". In the
event that the Administrative Agent receives such a notice, the Administrative


                                       58

<PAGE>

Agent shall give notice thereof to the Banks. The Administrative Agent shall
take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Majority Banks; provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Banks.

     SECTION 9.6. Non-Reliance on Administrative Agent and Other Banks. Each
Bank expressly acknowledges that neither the Agents nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or Affiliates have
made any representations or warranties to it and that no act by any Agent
hereinafter taken, including any review of the affairs of the Borrower, shall be
deemed to constitute any representation or warranty by any Agent to any Bank.
Each Bank represents to the Agents that it has, independently and without
reliance upon any Agent or any other Bank, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrower and made its own decision to make
its Loans hereunder and enter into this Agreement. Each Bank also represents
that it will, independently and without reliance upon any Agent or any other
Bank, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement and the other Loan
Documents, and to make such investigation as it deems necessary to inform itself
as to the business, operations, property, financial and other condition and
creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished to the Banks by the Administrative
Agent hereunder, the Administrative Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Borrower that may come into the
possession of the Administrative Agent or any of its officers, directors,
employees, Administrative Agent, attorneys-in-fact or Affiliates.

     SECTION 9.7. Indemnification. The Banks agree to indemnify the Agents and
the Lead Arrangers in their respective capacities as such (to the extent not
reimbursed by the Borrower and without limiting the obligation of the Borrower
to do so), ratably according to their respective applicable Revolving
Percentages in effect on the date on which indemnification is sought under this
Section 9.7, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (including, without limitation, at
any time following the payment of all amounts owing hereunder and the
termination of the Commitments) be imposed on, incurred by or asserted against
the Agents or the Lead Arrangers, as the case may be, in any way relating to or
arising out of this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agents or
the Lead Arrangers, as the case may be, under or in connection with any of the
foregoing; provided that no Bank shall be liable for the payment of any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agents' or
the Lead Arrangers', as the case may be, gross negligence or willful misconduct.
The agreements in this Section 9.7 shall survive the payment of all amounts
payable hereunder.


                                       59

<PAGE>

     SECTION 9.8. Agent in Its Individual Capacity. Each Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrower as though such Agent were not an Agent
hereunder and under the other Loan Documents. With respect to its Loans made or
renewed by it, any Letter of Credit issued or participated in by it and its
Commitment hereunder, each Agent shall have the same rights and powers under
this Agreement and the other Loan Documents as any Bank and may exercise the
same as though it were not an Agent, and the terms "Bank" and "Banks" shall
include the each Agent in its individual capacity.

     SECTION 9.9. Successor Administrative Agent. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Banks and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this Agreement and the other Loan Documents, then the Majority Banks shall
appoint from among the Banks a successor agent for the Banks, which successor
agent shall be approved by the Borrower, whereupon such successor agent shall
succeed to the rights, powers and duties of the Administrative Agent, and the
term "Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Agent or any of the parties to
this Agreement or any holders of any amounts payable hereunder; provided that if
an Event of Default has occurred and is continuing, no consent of the Borrower
shall be required. If a successor Administrative Agent shall not have been so
appointed within said 30-day period, the Administrative Agent may then appoint a
successor Administrative Agent who shall be a financial institution engaged or
licensed to conduct banking business under the laws of the United States with an
office in New York City and that has total assets in excess of $500,000,000 and
who shall serve as Administrative Agent until such time, if any, as an
Administrative Agent shall have been appointed as provided above. After any
retiring Administrative Agent's resignation or removal as Administrative Agent,
the provisions of this Article X shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Loan Documents.

     Notwithstanding anything to the contrary contained herein, no Bank
identified as an "Agent", "Arranger" or "Global Coordinator" other than the
Administrative Agent, shall have the right, power, obligation, liability,
responsibility or duty under this Agreement or any Loan Document other than
those applicable to all Banks as such. Without limiting the foregoing, none of
the Banks so identified shall have or be deemed to have any fiduciary
relationship with any Bank. Each Bank acknowledges that it has not relied, and
will not rely, on any of the Banks so identified in deciding to enter into this
Agreement or not taking action hereunder.

                                    ARTICLE X

                                  MISCELLANEOUS

     SECTION 10.1. Amendments and Waivers. Neither this Agreement, any Note, any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except pursuant to an instrument or instruments in
writing executed in accordance with the provisions of this Section 10.1. The
Majority Banks may, or, with the written consent of the Majority Banks, the
Administrative Agent may, from time to time, (a) enter into with the


                                       60

<PAGE>

Borrower written amendments, supplements or modifications hereto and to any
Notes and the other Loan Documents for the purpose of adding any provisions to
this Agreement or any Notes or the other Loan Documents or changing in any
manner the rights of the Banks or of the Borrower hereunder or thereunder or (b)
waive, on such terms and conditions as the Majority Banks or the Administrative
Agent, as the case may be, may specify in such instrument, any of the
requirements of this Agreement or any Notes or the other Loan Documents or any
Default or Event of Default and its consequences; provided, however, that no
such waiver and no such amendment, supplement or modification shall:

          (i) reduce the amount or extend the scheduled date of maturity of any
     Note or Loan, or reduce the stated rate of any interest or fee (including
     the prepayment premium provided for in Section 4.6) payable hereunder or
     extend the scheduled date of any payment thereof, or increase the amount or
     extend the expiration date of any Bank's Commitments, in each case without
     the consent of each Bank directly affected thereby;

          (ii) amend, modify or waive any provision of this Section or of
     Section 4.2 in a manner that would alter the pro rata sharing of payments
     required thereby, or reduce the percentage specified in the definition of
     Majority Banks, or consent to the assignment or transfer by the Borrower of
     any of its respective rights and obligations under this Agreement and the
     other Loan Documents, in each case without the written consent of all the
     Banks;

          (iii) amend, modify or waive any provision of Article IX without the
     written consent of the then Administrative Agent; or

          (iv) amend, modify or waive any provision of Section 2.4 in a manner
     that adversely affects any Issuing Bank without the written consent of the
     then Issuing Bank or Issuing Banks.

          Any such waiver and any such amendment, supplement or modification
shall apply equally to each of the Banks and shall be binding upon the Borrower,
the Banks, the Issuing Bank or Issuing Banks, the Administrative Agent and all
future holders of the amounts payable hereunder. In the case of any waiver (to
the extent specified therein), the Borrower, the Banks, the Issuing Bank or
Issuing Banks, and the Administrative Agent shall be restored to their former
position and rights hereunder and under any outstanding Notes and any other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing, but no such waiver shall extend to any subsequent or
other Default or Event of Default, or impair any right consequent thereon.

     SECTION 10.2. Notices. (a) Unless otherwise expressly provided herein, all
notices, requests and demands to or upon the respective parties hereto to be
effective shall be in writing (including by facsimile followed by any original
sent by mail or delivery), and, shall be deemed to have been duly given or made
when delivered by hand, or three days after being deposited in the mail, postage
prepaid, or, in the case of telecopy notice, when received, addressed as follows
in the case of the Borrower and the Administrative Agent, and as set forth in
Schedule 1.1(A) in the case of the other parties hereto, or to such other
address as may be hereafter notified by the respective parties hereto and any
future holders of the amounts payable hereunder:

provided that any notice, request or demand to or upon the Administrative Agent
or the Banks shall not be effective until received.

     (b) The Borrower hereby acknowledges that (i) certain 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 Borrower or its securities) (each, a
"Public Lender") and (ii) the Administrative Agent will make available to the
Lenders certain notices, requests, financial statements, financial and other
reports, certificates and other information materials, but excluding any such
communication that initiates or responds to the legal process (all such
non-excluded information being referred to herein collectively as the
"Communications") on IntraLinks or another relevant website (whether a
commercial, third-party website or whether sponsored by the Administrative
Agent) (the "Platform"). The Borrower hereby agrees that all Communications that
are to be made available to Public Lenders shall be clearly and conspicuously
marked "PUBLIC" which, at a minimum, shall mean that the word "PUBLIC" shall
appear prominently on the first page thereof, (ii) by marking Communications
"PUBLIC," the Borrower shall be deemed to have authorized the Administrative
Agent, the Issuing Banks and the Lenders to treat such Communications as not
containing any material non-public information with respect to the Borrower or
its securities for purposes of United States Federal and state securities laws,
it being understood that certain of such Communications may be subject to the
confidentiality requirements hereof, (iii) all Communications marked "PUBLIC"
are permitted to be made available through a portion of the Platform designated
"Public Investor," and (iv) the Administrative Agent shall be entitled to treat
any Communications that are not marked "PUBLIC" as being suitable only for
posting on a portion of the Platform not designated "Public


                                       62

<PAGE>

Investor." Notwithstanding the foregoing, (A) the Borrower shall be under no
obligation to mark any Communications "PUBLIC," and each Public Lender hereby
waives its right to receive any Communications that are not marked "PUBLIC"; and
(B) the Administrative Agent shall treat Communications that are deemed to have
been delivered based on notice pursuant to the last sentence of Section 7.1(a)
as "PUBLIC."

     SECTION 10.3. No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of the Administrative Agent or any Bank, any
right, remedy, power or privilege hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

     SECTION 10.4. Survival of Representations and Warranties. All
representations and warranties made hereunder and in any document, certificate
or statement delivered pursuant hereto or in connection herewith shall survive
the execution and delivery of this Agreement.

     SECTION 10.5. Payment of Expenses and Taxes; Indemnity. The Borrower agrees
(a) to pay all reasonable out-of-pocket expenses of the Global Coordinators
associated with the syndication of the Facility, (b) to pay or reimburse the

costs and expenses incurred in connection with the development, preparation,
negotiation and execution and delivery of, and any amendment, supplement or
modification to, this Agreement and any Notes and the other Loan Documents and
any other documents prepared in connection herewith or therewith, and the
consummation and administration of the transactions contemplated hereby and
thereby, including, without limitation, the reasonable fees and disbursements of
Simpson Thacher & Bartlett LLP, special counsel to the Administrative Agent (but
excluding the fees or expenses of any other counsel), (c) to pay or reimburse
the Administrative Agent for all its costs and expenses incurred in connection
with the enforcement or preservation of any rights under this Agreement, any
Notes, the other Loan Documents and any such other documents, including, without
limitation, the reasonable fees and disbursements of the special counsel to the
Administrative Agent, (d) to pay or reimburse each Bank for all its costs and
expenses incurred in connection with the enforcement, or at any time after the
occurrence and during the continuance of a Default or an Event of Default the
preservation, of any rights under this Agreement, any Notes, the other Loan
Documents and any such other documents, including, without limitation, the
reasonable fees and disbursements of counsel to such Bank, (e) without
duplication of any other provision contained in this Agreement or any Notes, to
pay, indemnify, and hold each Bank and the Administrative Agent harmless from,
any and all recording and filing fees, if any, and any and all liabilities (for
which each Bank has not been otherwise reimbursed under this Agreement) with
respect to, or resulting from any delay in paying, stamp, excise and other
taxes, if any, that may be payable or determined to be payable in connection
with the execution and delivery of, or consummation or administration of any of
the transactions contemplated by, or any amendment, supplement or modification
of, or any waiver or consent under or in respect of, this Agreement, any Notes,
the other Loan Documents and any such other documents, and (f) without
duplication of any other provision contained in this Agreement or any Notes, to

<PAGE>

directors, officers, employees, agents, trustees, advisors and affiliates
(collectively, "Indemnified Persons") harmless from and against, any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
(including without limitation, all fees and expenses of counsel to any
indemnified person) with respect to the execution, delivery, enforcement,
performance and administration of this Agreement, any Notes or the other Loan
Documents, the transactions contemplated by this Agreement, any Notes or the
other Loan Documents, or the use, or proposed use, of proceeds of the Loans (all
the foregoing in this clause (f), collectively, the "Indemnified Liabilities");
provided that the Borrower shall have no obligation hereunder to an Indemnified
Person with respect to Indemnified Liabilities arising from the gross negligence
or willful misconduct of such Indemnified Person, AND PROVIDED FURTHER THAT IT
IS THE INTENTION OF THE BORROWER TO INDEMNIFY THE INDEMNIFIED PERSONS AGAINST
THE CONSEQUENCES OF THEIR OWN NEGLIGENCE. The agreements in this Section 10.5
shall survive repayment of the Loans and all other amounts payable hereunder.

     SECTION 10.6. Effectiveness, Successors and Assigns, Participations;
Assignments. (a) This Agreement shall become effective on the date hereof and
thereafter shall be binding upon and inure to the benefit of the Borrower, the
Banks, each Issuing Bank, the Administrative Agent, all future holders of the
Loans and their respective successors and assigns, except that the Borrower may
not assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of each Bank.

     (b) Any Bank may, in the ordinary course of its business and in accordance
with applicable law, at any time sell to one or more banks or other financial
institutions or Bank Affiliates (a "Participant") participating interests in any
Loan owing to such Bank, any Note held by such Bank, any Commitment of such Bank
or any other interest of such Bank hereunder and under the other Loan Documents.
In the event of any such sale by a Bank of a participating interest to a
Participant, such Bank's obligations under this Agreement to the other parties
to this Agreement shall remain unchanged, such Bank shall remain solely
responsible for the performance thereof, such Bank shall remain the holder of
any such Loan and Commitment or other interest for all purposes under this
Agreement and the other Loan Documents, the Borrower and the Administrative
Agent shall continue to deal solely and directly with such Bank in connection
with such Bank's rights and obligations under this Agreement and the other Loan
Documents and except with respect to the matters set forth in Section 10.1, the
amendment of which requires the consent of all of the Banks, the participation
agreement between the selling Bank and the Participant may not restrict such
Bank's voting rights hereunder. The Borrower agrees that each Participant, to
the extent provided in its participation, shall be entitled to the benefits of
Sections 3.4, 3.7, 4.1 and 4.3 with respect to its participation in the
Commitments and the Loans outstanding from time to time; provided that (i) no
Participant shall be entitled to receive any greater amount pursuant to such
Sections than the selling Bank would have been entitled to receive in respect of
the amount of the participation sold by such selling Bank to such Participant
had no such sale occurred and (ii) each such sale of participating interests
shall be to a "qualified purchaser", as such term is defined under the
Investment Company Act of 1940. Except as expressly provided in this Section
10.6(b), no Participant shall be a third-party beneficiary of or have any rights
under this Agreement or under any of the other Loan Documents.


                                       64

<PAGE>

     (c) Except as set forth below, the Banks shall be permitted to assign all
or a portion of their Loans and Commitments to one or more financial
institutions ("Purchasing Banks") with the consent, not to be unreasonably
withheld, of (a) the Borrower, unless (i) the Purchasing Bank is a Bank or a
Bank Affiliate or (ii) an Event of Default has occurred and is continuing, (b)
the Administrative Agent, unless the assignment is from a Bank to its Bank
Affiliate, and (c) each Issuing Bank, unless the assignment is from a Bank to
its Bank Affiliate pursuant to an Assignment and Acceptance, substantially in
the form of Exhibit C (an "Assignment and Acceptance"), executed by such
Purchasing Bank and such transferor Bank (and by the Borrower, the
Administrative Agent and each Issuing Bank, as applicable) and delivered to the
Administrative Agent for its acceptance and recording in the Register; provided
that (i) such Purchasing Bank is a "qualified purchaser" as defined under the
Investment Company Act of 1940, (ii) each such sale shall be of a uniform, and
not a varying, percentage of all rights and obligations under and in respect of
the Commitment of such Bank, (iii) each such sale shall be in an aggregate
amount of not less than $5,000,000 (or such lesser amount representing the
entire Commitment of such transferor Bank) if such sale is not to an existing
Bank and (iv) after giving effect to such sale, the transferor Bank shall (to
the extent that it continues to have any Commitment hereunder) have a Commitment
of not less than $5,000,000, provided that such amounts shall be aggregated in
respect of each Bank and its Bank Affiliates, if any. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance (the "Transfer Effective Date"), (i)
the Purchasing Bank thereunder shall be a party hereto and, to the extent
provided in such Assignment and Acceptance, have the rights and obligations of a
Bank hereunder with the Commitments as set forth therein and (ii) the transferor
Bank thereunder shall, to the extent provided in such Assignment and Acceptance,
be released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of a transferor
Bank's rights and obligations under this Agreement, such transferor Bank shall
cease to be a party hereto). Such Assignment and Acceptance shall be deemed to
amend this Agreement to the extent, and only to the extent, necessary to reflect
the addition of such Purchasing Bank and the resulting adjustment of Revolving
Percentages arising from the purchase by such Purchasing Bank of all or a
portion of the rights and obligations of such transferor Bank under this
Agreement. On or prior to the Transfer Effective Date determined pursuant to
such Assignment and Acceptance, (i) appropriate entries shall be made in the
accounts of the transferor Bank and the Register evidencing such assignment and
releasing the Borrower from any and all obligations to the transferor Bank in
respect of the assigned Loan or Loans and (ii) appropriate entries evidencing
the assigned Loan or Loans shall be made in the accounts of the Purchasing Bank
and the Register as required by Section 3.1 hereof. In the event that any Notes
have been issued in respect of the assigned Loan or Loans, such Notes shall be
marked "cancelled" and surrendered by the transferor Bank to the Administrative
Agent for return to the Borrower.

     (d) The Administrative Agent shall maintain at its address referred to in
Section 10.2(a) a copy of each Assignment and Acceptance delivered to it and a
register (the "Register") for the recordation of the names and addresses of the
Banks and the Commitments of, and principal amount of the Loans owing to, each
Bank from time to time. To the extent permitted by applicable law, the entries
in the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Banks may (and, in the case of any
Loan or other obligations hereunder not evidenced by a Note, shall) treat, each
Person whose name is recorded in the Register as the owner of a Loan or other
obligation hereunder as the


                                       65

<PAGE>

owner thereof for all purposes of this Agreement and the other Loan Documents,
notwithstanding any notice to the contrary. Any assignment of any Loan or other
obligation hereunder not evidenced by a Note shall be effective only upon
appropriate entries with respect thereto being made in the Register. The
Register shall be available for inspection by the Borrower or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

     (e) Upon its receipt of an Assignment and Acceptance executed by a
transferor Bank and Purchasing Bank (and, in the case of a Purchasing Bank that
is not then a Bank Affiliate, by the Borrower and the Administrative Agent)
together with payment to the Administrative Agent of a registration and
processing fee of $3,500, the Administrative Agent shall promptly accept such
Assignment and Acceptance on the Transfer Effective Date determined pursuant
thereto, record the information contained therein in the Register and give
notice of such acceptance and recordation to the Banks and the Borrower.

     (f) Each of the Banks and the Administrative Agent agrees to exercise its
best efforts to keep, and to cause any third party recipient of the information
described in this Section 10.6(f) to keep, any information delivered or made
available by the Borrower to it (including any information obtained pursuant to
Section 7.1), confidential from anyone other than Persons employed or retained
by such party who are or are expected to become engaged in evaluating,
approving, structuring or administering the transactions contemplated hereunder;
provided that nothing shall prevent any Bank or the Administrative Agent from
disclosing such information (i) to any other Bank or any Affiliate of any Bank,
(ii) pursuant to subpoena or upon the order of any court or administrative
agency, (iii) upon the request or demand of any Governmental Authority having
jurisdiction over such Bank, (iv) if such information has been publicly
disclosed, (v) to the extent reasonably required in connection with any
litigation to which either the Administrative Agent, any Bank, the Borrower or
their respective Affiliates may be a party, (vi) to the extent reasonably
required in connection with the exercise of any remedy hereunder, (vii) to the
Administrative Agent's or such Bank's, as the case may be, legal counsel,
independent auditors and other professional advisors, or (viii) to any actual or
proposed Participant, Purchasing Bank or pledgee (each, a "Transferee") that has
agreed in writing to be bound by the provisions of this Section 10.6(f). To the
extent permitted by applicable law, in the event that any Bank or the
Administrative Agent is legally requested or required to disclose any
confidential information pursuant to clause (ii), (iii), or (v) of this Section
10.6(f), such party shall promptly notify the Borrower of such request or
requirement prior to disclosure so that Borrower may seek an appropriate
protective order and/or waive compliance with the terms of this Agreement. If,
however, in the opinion of counsel for such party, such party is nonetheless, in
the absence of such order or waiver, compelled to disclose such confidential
information or otherwise stand liable for contempt or suffer possible censure or
other penalty or liability, then such party may disclose such confidential
information without liability to the Borrower; provided, however, that such
party will use its best efforts to minimize the disclosure of such information.
Subject to the exceptions above to disclosure of information, each of the Banks
and the Administrative Agent agrees that it shall not publish, publicize, or
otherwise make public any information regarding this Agreement or the
transactions contemplated hereby without the written consent of the Borrower, in
its sole discretion.


                                       66

     (g) If, pursuant to this Section 10.6, any interest in this Agreement or
any Loan or L/C Obligation is transferred to any Transferee that is organized
under the laws of any jurisdiction other than the United States or any state
thereof, the transferor Bank shall cause such Transferee, concurrently with the
effectiveness of such transfer, (i) to deliver to the transferor Bank (and, in
the case of any Purchasing Bank registered in the Register, the Administrative
Agent and the Borrower) either U.S. Internal Revenue Service Form W-8BEN or U.S.
Internal Revenue Service Form W-8ECI, or successor applicable forms (wherein
such Transferee claims entitlement to complete exemption from U.S. federal
withholding tax on all interest payments hereunder) and (ii) to agree (for the
benefit of the transferor Bank, the Administrative Agent and the Borrower) to
deliver to the transferor Bank (and, in the case of any Purchasing Bank
registered in the Register, the Administrative Agent and Borrower) a new Form
duly executed and completed W-8BEN or W-8ECI, or successor applicable forms or
other manner of certification, as the case may be, upon the expiration or
obsolescence of any previously delivered form in accordance with applicable U.S.
laws and regulations and amendments, unless in any such case any change in
treaty, law or regulation has occurred prior to the date on which any such
delivery would otherwise be required that renders all such forms inapplicable or
that would prevent such Transferee from duly completing and delivering any such
form with respect to it and such Transferee so advises the transferor Bank (and,
in the case of any Purchasing Bank registered in the Register, the
Administrative Agent and the Borrower).

     (h) Any Bank may at any time pledge or assign a security interest in all or
any portion of its rights under this Agreement to secure obligations of such
Bank, including any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment
of a security interest; provided that no such pledge or assignment of a security
interest shall release a Bank from any of its obligations hereunder or
substitute any such pledgee or Purchasing Bank for such Bank as a party hereto.
The Borrower hereby agrees that, upon request of any Bank at any time and from
time to time after the Borrower has made its initial Borrowing hereunder, the
Borrower shall provide to such Bank, at the Borrower's own expense, a promissory
note, substantially in the form of Exhibit D evidencing the Loans or L/C
Obligations, as the case may be, owing to such Bank.

     SECTION 10.7. Setoff. In addition to any rights and remedies of the Banks
provided by law, each Bank shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder or under the Loans to which it is a party (whether at the
stated maturity, by acceleration or otherwise) to setoff and appropriate and
apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Bank or any branch or agency thereof to or for the credit or the
account of the Borrower. Each Bank agrees promptly to notify the Borrower and
the Administrative Agent after any such setoff and application made by such
Bank, provided that the failure to give such notice shall not affect the
validity of such setoff and application.

     SECTION 10.8. Counterparts. This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts, and all
of said counterparts taken together shall be deemed to constitute one and the
same instrument. A set of the copies of


                                       67

<PAGE>

this Agreement signed by all the parties shall be maintained with Borrower and
the Administrative Agent.

     SECTION 10.9. Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

     SECTION 10.10. Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Administrative Agent and the Banks
with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by the Administrative Agent or any
Bank relative to the subject matter hereof not expressly set forth or referred
to herein or in the other Loan Documents.

     SECTION 10.11. GOVERNING LAW. (a) THIS AGREEMENT AND ANY NOTES OR OTHER
LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS
AGREEMENT AND ANY NOTES AND ANY OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     (b) Notwithstanding anything in Section 10.11(a) to the contrary, nothing
in this Agreement or in any Note or any other Loan Documents shall be deemed to
constitute a waiver of any rights which any Bank may have under applicable
federal law relating to the amount of interest which any Bank may contract for,
take, receive or charge in respect of any Loans, including any right to take,
receive, reserve and charge interest at the rate allowed by the laws of the
state where such Bank is located. To the extent that Texas law is applicable to
the determination of the Highest Lawful Rate, the Banks and the Borrower agree
that (i) if Chapter 303 of the Texas Finance Code, as amended, is applicable to
such determination, the weekly rate ceiling (formerly known as the indicated
(weekly) rate ceiling in Article 1.04, Subtitle 1, Title 79, of the Revised
Civil Statutes of Texas, as amended) as computed from time to time shall apply,
provided that, to the extent permitted by such Article, the Administrative Agent
may from time to time by notice to the Borrower revise the election of such
interest rate ceiling as such ceiling affects the then current or future
balances of the Loans; and (ii) the provisions of Chapter 346 of the Texas
Finance Code, as amended (formerly found in Chapter 15 of Subtitle 3, Title 79,
of the Revised Civil Statutes of Texas, 1925, as amended) shall not apply to
this Agreement or any Note issued hereunder.

     SECTION 10.12. Submission to Jurisdiction; Waivers. The Borrower hereby
irrevocably and unconditionally:

     (a) submits for itself and its property in any legal action or proceeding
relating to this Agreement and the other Loan Documents to which it is a party,
or for recognition and enforcement of any judgment in respect thereof, to the
non-exclusive general jurisdiction of the Courts of the State of New York, the
courts of the United States of America for the Southern District of New York,
and appellate courts from any thereof;


                                       68

<PAGE>

     (b) consents that any such action or proceeding may be brought in such
courts and waives any objection that it may now or hereafter have to the venue
of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

     (c) agrees that service of process in any such action or proceeding may be
effected by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid to the Borrower at its
address set forth in Section 10.2 or at such other address of which the
Administrative Agent shall have been notified pursuant thereto;

     (d) agrees that nothing herein shall affect the right to effect service of
process in any other manner permitted by law or shall limit the right to sue in
any other jurisdiction; and

     (e) waives, to the maximum extent permitted by applicable law, any right it
may have to claim or recover in any legal action or proceeding any special,
exemplary, punitive or consequential damages.

     SECTION 10.13. Acknowledgments. The Borrower hereby acknowledges that:

     (a) it has been advised by counsel in the negotiation, execution and
delivery of this Agreement, any Notes and the other Loan Documents;

     (b) neither the Administrative Agent nor any Bank has any fiduciary
relationship with or duty to the Borrower arising out of or in connection with
this Agreement or any of the other Loan Documents, and the relationship between
the Administrative Agent and the Banks, on one hand, and the Borrower, on the
other hand, in connection herewith or therewith is solely that of debtor and
creditor; and

     (c) no joint venture exists among the Banks or among the Borrower and the
Banks.

     SECTION 10.14. Limitation on Agreements. All agreements between the
Borrower, the Administrative Agent or any Bank, whether now existing or
hereafter arising and whether written or oral, are hereby expressly limited so
that in no contingency or event whatsoever, whether by reason of demand being
made in respect of an amount due under any Loan Document or otherwise, shall the
amount paid, or agreed to be paid, to the Administrative Agent or any Bank for
the use, forbearance, or detention of the money to be loaned under this
Agreement, any Notes or any other Loan Document or otherwise or for the payment
or performance of any covenant or obligation contained herein or in any other
Loan Document exceed the Highest Lawful Rate. If, as a result of any
circumstances whatsoever, fulfillment of any provision hereof or of any of such
documents, at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by applicable usury law, then,
ipso facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if, from any such circumstance, the Administrative Agent or any
Bank shall ever receive interest or anything that might be deemed interest under
applicable law that would exceed the Highest Lawful Rate, such amount that would
be excessive interest shall be applied to the reduction of the principal amount
owing on account of such Bank's Loans or the amounts owing on other obligations
of the Borrower to the Administrative Agent or any Bank under any Loan Document
and not to the payment of interest, or if such excessive interest exceeds the
unpaid principal balance of such


                                       69

<PAGE>

Bank's Loans and the amounts owing on other obligations of the Borrower to the
Administrative Agent or any Bank under any Loan Document, as the case may be,
such excess shall be refunded to the Borrower. All sums paid or agreed to be
paid to the Administrative Agent or any Bank for the use, forbearance or
detention of the indebtedness of the Borrower to the Administrative Agent or any
Bank shall, to the fullest extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full term of such indebtedness
until payment in full of the principal (including the period of any renewal or
extension thereof) so that the interest on account of such indebtedness shall
not exceed the Highest Lawful Rate. Notwithstanding anything to the contrary
contained in any Loan Document, it is understood and agreed that if at any time
the rate of interest that accrues on the outstanding principal balance of any
Loan shall exceed the Highest Lawful Rate, the rate of interest that accrues on
the outstanding principal balance of any Loan shall be limited to the Highest
Lawful Rate, but any subsequent reductions in the rate of interest that accrues
on the outstanding principal balance of any Loan shall not reduce the rate of
interest that accrues on the outstanding principal balance of any Loan below the
Highest Lawful Rate until the total amount of interest accrued on the
outstanding principal balance of any Loan equals the amount of interest that
would have accrued if such interest rate had at all times been in effect. The
terms and provisions of this Section 10.14 shall control and supersede every
other provision of all Loan Documents.

     SECTION 10.15. Removal of Bank. Notwithstanding anything herein to the
contrary, the Borrower may, at any time in its sole discretion, remove any Bank
upon 15 Business Days' written notice to such Bank and the Administrative Agent
(the contents of which notice shall be promptly communicated by the
Administrative Agent to each other Bank), such removal to be effective at the
expiration of such 15-day notice period; provided, however, that no Bank may be
removed hereunder at a time when an Event of Default shall have occurred and be
continuing. Each notice by the Borrower under this Section 10.15 shall
constitute a representation by the Borrower that the removal described in such
notice is permitted under this Section 10.15. Concurrently with such removal,
the Borrower shall pay to such removed Bank all amounts owing to such Bank
hereunder and under any other Loan Document in immediately available funds. Upon
full and final payment hereunder of all amounts owing to such removed Bank, such
Bank shall make appropriate entries in its accounts evidencing payment of all
Loans hereunder and releasing the Borrower from all obligations owing to the
removed Bank in respect of the Loans hereunder and surrender to the
Administrative Agent for return to the Borrower any Notes of the Borrower then
held by it. Effective immediately upon such full and final payment, such removed
Bank will not be considered to be a "Bank" for purposes of this Agreement except
for the purposes of any provision hereof that by its terms survives the
termination of this Agreement and the payment of the amounts payable hereunder.
Effective immediately upon such removal, the Commitments of such removed Bank
shall immediately terminate and such Bank's participation share in any
outstanding Letters of Credit shall immediately terminate and such participation
share shall be divided among the remaining Banks according to their Revolving
Percentages. Such removal will not, however, affect the Commitments of any other
Bank hereunder.

     SECTION 10.16. Officer's Certificates. It is not intended that any
certificate of any officer of the Borrower delivered to the Administrative Agent
or any Bank pursuant to this Agreement shall give rise to any personal liability
on the part of such officer.


                                       70

     SECTION 10.17. USA Patriot Act. Each Bank and the Administrative Agent (for
itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the "Patriot Act"), it is required to
obtain, verify and record information that identifies the Borrower, which
information includes the name and address of the Borrower and other information
that will allow such Bank or the Administrative Agent, as applicable, to
identify the Borrower in accordance with the Patriot Act. The Borrower shall,
and shall cause each of its Subsidiaries to, provide, to the extent commercially
reasonable, such information and take such actions as are reasonably requested
by each Bank and the Administrative Agent to maintain compliance with the
Patriot Act.
