Equity Interests of which are acquired after the date thereof by the Borrower
and/or a Subsidiary of the Borrower or (b) any assets constituting a separately
identifiable business or operating unit or division acquired on or after the
date hereof by the Borrower or a Subsidiary of the Borrower.

          "Adjusted LIBO Rate" means, with respect to any Eurodollar Borrowing

<PAGE>

          "Agreement" means this Credit Agreement, as the same may at any time
be amended, supplemented or otherwise modified in accordance with the terms
hereof and in effect.

          "Alternate Base Rate" means, for any day, a rate per annum equal to
the greater of (a) the Prime Rate in effect on such day and (b) the Federal
Funds Effective Rate in effect on such day plus 1/2 of 1%. Any change in the
Alternate Base Rate due to a change in the Prime Rate or the Federal Funds
Effective Rate shall be effective from and including the effective date of such
change in the Prime Rate or the Federal Funds Effective Rate, respectively.

          "Applicable Commitment Fee Rate" means, with respect to the Revolving
Credit Commitments, for any period, the applicable percentage per annum equal to
the percentage set forth below determined by reference to the category
containing the lower of (a) the rating applicable to the Facilities from S&P or
(b) the rating applicable to the Facilities from Moody's, in each case as in
effect from time to time during such period:

     ----------------------------------------------------------------------
                Facilities Ratings                     Applicable
                 (S&P or Moody's)                    Commitment Fee
                                                          Rate
     ----------------------------------------------------------------------

     Category 1:                                         0.200%
     BBB+ or better and Baa1 or better
     ----------------------------------------------------------------------
     Category 2:
     BBB or Baa2                                         0.250%

     Category 3:
     BBB- or Baa3                                        0.325%
     ----------------------------------------------------------------------
     Category 4:
     BB+ or Ba1                                          0.375%

     Category 5:
     Worse than or equal to BB or Ba2                    0.500%
     ----------------------------------------------------------------------

provided, that (i) if, at any time, neither S&P nor Moody's makes available any
rating with respect to the Facilities, the Applicable Commitment Fee Rate shall
be 0.500% and (ii) if the ratings established by S&P or Moody's for the
Facilities shall be changed (other than as a result of a change in the rating
system of S&P or Moody's), such change shall be effective as of the date on
which it is first announced by the applicable rating agency, irrespective of
when notice of such change shall have been furnished by the Borrower to the
Agent and the Lenders pursuant to Section 5.01 or otherwise. Each change in the
Applicable Commitment Fee Rate shall apply during the period commencing on the
effective date of such change and ending on the date immediately preceding the
effective date of the next such change. If the rating system of S&P or Moody's
shall change, or if either such rating agency (including any successor to its
rating agency business) shall cease to be in the business of rating corporate
debt obligations, the Borrower and the Lenders shall negotiate in good faith to
amend this definition to reflect such changed rating system or the
unavailability of ratings from such rating agency (including any successor to
its rating agency business) and, pending the effectiveness of any such
amendment, the Applicable Commitment Fee Rate shall be determined using the S&P
or Moody's rating, as the case may be, most recently in effect prior to such
change or cessation.

          "Applicable Interest Rate Margin" means, with respect to (a) any Term
B Loans comprising (i) ABR Loans, 1.25% per annum and (ii) Eurodollar Loans,
2.25% per annum; and (b) any Revolving Loans or any Term A Loans comprising,

of such Interest Period:

Borrower receives such notice, if such notice is not received prior to such time
on the day of receipt; provided that the Borrower may, subject to the conditions
to borrowing set forth herein, request in accordance with Section 2.03 that such
payment be financed with an ABR Revolving Borrowing (only if such L/C
Disbursement is not less than $1,000,000), or a Swingline Loan in an equivalent
amount and, to the extent so financed, the Borrower's obligation to make such
payment shall be discharged and replaced by the resulting ABR Revolving
Borrowing or Swingline Loan. If the Borrower fails to make such payment or
discharge such reimbursement obligation when due or in accordance with

                                      -28-

<PAGE>

the prior sentence, the Administrative Agent shall notify each Revolving Lender
of the applicable L/C Disbursement, the payment then due from the Borrower in
respect thereof and such Revolving Lender's Applicable Percentage thereof.
Promptly following receipt of such notice, each Revolving Lender shall pay to
the Administrative Agent its Applicable Percentage of the payment then due from
the Borrower, in the same manner as provided in Section 2.06 with respect to
Loans made by such Revolving Lender (and Section 2.06 shall apply, mutatis
mutandis, to the payment obligations of the Revolving Lenders), and the
Administrative Agent shall promptly pay to the Issuing Bank the amounts so
received by it from the Revolving Lenders. Promptly following receipt by the
Administrative Agent of any payment from the Borrower pursuant to this paragraph
(e) of this Section 2.05, the Administrative Agent shall distribute such payment
to the Issuing Bank or, to the extent that Revolving Lenders have made payments
pursuant to this paragraph to reimburse the Issuing Bank, then to such Revolving
Lenders and the Issuing Bank as their interests may appear. Any payment made by
a Revolving Lender pursuant to this paragraph (e) of this Section 2.05 to
reimburse the Issuing Bank for any L/C Disbursement (other than the funding of
ABR Revolving Loan or a Swingline Loan as contemplated above) shall not
constitute a Loan and shall not relieve the Borrower of its obligation to
reimburse such L/C Disbursement.

          (f) Obligations Absolute. The Borrower's obligation to reimburse L/C
Disbursements as provided in paragraph (e) of this Section 2.05 shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein, (ii) any
draft or other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect to any statement therein being untrue or
inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of
Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for
the provisions of this Section 2.05, constitute a legal or equitable discharge
of, or provide a right of setoff against, the Borrower's obligations hereunder.
Neither the Administrative Agent, the Revolving Lenders nor the Issuing Bank,
nor any of their Related Parties, shall have any liability or responsibility by
reason of or in connection with the issuance or transfer of any Letter of Credit
or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to in the preceding sentence), or any error,
omission, interruption, loss or delay in transmission or delivery of any draft,
notice or other communication under or relating to any Letter of Credit
(including any document required to make a drawing thereunder), any error in
interpretation of technical terms or any consequence arising from causes beyond
the control of the Issuing Bank; provided that the foregoing shall not be
construed to excuse the Issuing Bank from liability to the Borrower to the
extent of any direct damages (as opposed to consequential damages, claims in
respect of which are hereby waived by the Borrower to the extent permitted by
applicable law) suffered by the Borrower that are caused by the Issuing Bank's
failure to exercise care when determining whether drafts and other documents
presented under a Letter of Credit comply with the terms thereof. The parties
hereto expressly agree that, in the absence of gross negligence, bad faith or
willful misconduct on the part of the Issuing Bank (as finally determined by a
court of competent jurisdiction), the Issuing Bank shall be deemed to have
exercised care in each such determination. In furtherance of the foregoing and
without limiting the generality thereof, the parties agree that, with respect to
documents presented which appear on their face to be in substantial compliance
with the terms of a Letter of Credit, the Issuing Bank may, in its sole
discretion, either accept and make payment upon such documents without

                                      -29-

<PAGE>

responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit. The Issuing Bank shall promptly
notify the Administrative Agent and the Borrower by telephone (confirmed by
telecopy) of such demand for payment and whether the Issuing Bank has made or
will make an L/C Disbursement thereunder; provided that any failure to give or
delay in giving such notice shall not relieve the Borrower of its obligation to
reimburse the Issuing Bank and the Revolving Lenders with respect to any such
L/C Disbursement in accordance with Section 2.05(e) after receipt of the notice
from the Issuing Bank contemplated thereby.

          (h) Interim Interest. If the Issuing Bank shall make any L/C
Disbursement, then, unless the Borrower shall reimburse such L/C Disbursement in
full on the date such L/C Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such L/C Disbursement is
made to but excluding the date that the Borrower reimburses such L/C
Disbursement, at the rate per annum then applicable to ABR Revolving Loans;
provided that, if the Borrower fails to reimburse such L/C Disbursement when due
pursuant to paragraph (e) of this Section 2.05, then Section 2.12(c) shall
apply. Interest accrued pursuant to paragraph (e) of this Section 2.05 shall be
for the account of the Issuing Bank, except that interest accrued on and after
the date of payment by any Revolving Lender pursuant to paragraph (e) of this
Section 2.05 to reimburse the Issuing Bank shall be for the account of such
Revolving Lender to the extent of such payment.

          (i) Replacement of the Issuing Bank. The 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 Revolving Lenders of any such replacement of the Issuing
Bank. At the time any such replacement shall become effective, the Borrower
shall pay all unpaid fees accrued for the account of the replaced Issuing Bank
pursuant to Section 2.11(b)(ii). From and after the effective date of any such
replacement, (i) the successor Issuing Bank shall have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Letters of
Credit to be 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 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.

          (j) Cash Collateralization. If any Event of Default shall occur and be
continuing, on the Business Day that the Borrower receives notice from the
Administrative Agent or the Required Class Lenders under the Revolving Credit
Facility (or, if the maturity of the Loans has been accelerated, Revolving
Lenders with L/C Exposure representing greater than 50% of the total L/C
Exposure) demanding the deposit of cash collateral pursuant to this paragraph
(j) of this Section 2.05, the Borrower shall deposit in an account with the
Administrative Agent, in the name of the Administrative Agent and for the
benefit of the Revolving Lenders, an amount in cash equal to the L/C Exposure as
of such date plus any accrued and unpaid interest thereon;

                                      -30-

<PAGE>

provided that the obligation to deposit such cash collateral shall become
effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any
Event of Default with respect to the Borrower described in paragraph (i) or (j)
of Article VII. Such deposit shall be held by the Administrative Agent as
collateral for the payment and performance of the Obligations of the Borrower.
The Administrative Agent shall have exclusive dominion and control, including
the exclusive right of withdrawal, over such account. Other than any interest
earned on the investment of such deposits, which investments shall be made at
the option and sole discretion of the Administrative Agent and at the Borrower's
risk and expense, such deposits shall not bear interest. Interest or profits, if
any, on such investments shall accumulate in such account. Moneys in such
account shall be applied by the Administrative Agent to reimburse the Issuing
Bank for L/C Disbursements for which it has not been reimbursed and, to the
extent not so applied, shall be held for the satisfaction of the reimbursement
obligations of the Borrower for the L/C Exposure at such time or, if the
maturity of the Loans has been accelerated (but subject to the consent of
Revolving Lenders with L/C Exposure representing greater than 50% of the total
L/C Exposure), be applied to satisfy other obligations of the Borrower under
this Agreement. If the Borrower is required to provide an amount of cash
collateral hereunder as a result of the occurrence of an Event of Default, such
amount (to the extent not applied as aforesaid) shall be returned to the
Borrower within three Business Days after all Events of Default have been cured
or waived.

           SECTION 2.06. Funding of Borrowings. (a) Each Lender shall make each
Loan committed to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds by 12:00 noon, New York City time, to
the account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders, provided, that Swingline Loans shall be made
as provided in Section 2.04. The Administrative Agent will make such Loans
available to the Borrower by promptly crediting the aggregate amounts so
received from the Lenders, in immediately available funds, to an account of the
Borrower maintained with the Administrative Agent in New York City and
designated by the Borrower in the applicable Borrowing Request; provided, that
ABR Revolving Loans made to finance the reimbursement of an L/C Disbursement as
provided in Section 2.05(e) shall be remitted by the Administrative Agent to the
Issuing Bank.

           (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
2.06 and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, the
Administrative Agent shall be entitled to recover such corresponding amount on
demand from such Lender for each day from and including the date such amount is
made available to the Borrower to but excluding the date of payment to the
Administrative Agent at the greater of (x) the Federal Funds Effective Rate and
(y) a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation. If such Lender does not pay such
corresponding amount with interest thereon upon Administrative Agent's demand
therefor and Administrative Agent previously made such amount available to
Borrower, Administrative Agent shall promptly notify Borrower and, if so
notified, Borrower shall immediately pay such corresponding amount to
Administrative Agent at the interest rate applicable to the relevant Borrowing
for each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the

                                      -31-

<PAGE>

Administrative Agent. If such Lender pays such amount to the Administrative
Agent, then such amount shall constitute such Lender's Loan included in such
Borrowing.

           SECTION 2.07. Interest Elections. (a) Each Revolving Borrowing
initially shall be of the Type specified in the applicable Borrowing Request
and, in the case of a Eurodollar Revolving Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request. Each Borrowing of Term
Loans shall initially be of a Type as provided in Section 2.02(c). Thereafter,
the Borrower may elect to convert each such Borrowing to a different Type or to
continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect
Interest Periods therefor, all as provided in this Section 2.07. The Borrower
may elect different Type options with respect to different portions of each
affected Borrowing, in which case each such portion shall be allocated ratably
among the applicable Lenders holding the Loans constituting such Borrowing, and
the Loans constituting each such portion shall be considered a separate
Borrowing. This Section 2.07 shall not apply to Swingline Borrowings and
accordingly no Swingline Borrowings may be converted or continued.

           (b) To make an election pursuant to this Section 2.07, the Borrower
shall notify the Administrative Agent of such election by telephone by the time
that a Borrowing Request would be required under Section 2.03 if the Borrower
were requesting a Revolving Borrowing of the Type resulting from such election
to be made on the effective date of such election. Each such telephonic Interest
Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Administrative Agent of a written Interest Election
Request substantially in the form attached as Exhibit F and signed by the
Borrower.

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

           (i)   the Borrowing to which such Interest Election Request applies
     and, if different options are being elected with respect to different
     portions thereof, the portions thereof to be allocated to each resulting
     Borrowing (in which case the information to be specified pursuant to
     paragraphs (iii) and (iv) below of this Section 2.07(c) shall be specified
     for each resulting Borrowing);

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

           (iii) whether the resulting Borrowing is to be an ABR Borrowing or a
     Eurodollar Borrowing; and

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

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

                                      -32-

<PAGE>

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

           (e) If the Borrower fails to deliver a timely Interest Election
Request with respect to a Eurodollar Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the Administrative Agent, at the
request of the Required Lenders, so notifies the Borrower, then, so long as an
Event of Default is continuing (i) no outstanding Revolving Borrowing may be
converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each
Eurodollar Revolving Borrowing shall be converted to an ABR Borrowing at the end
of the Interest Period applicable thereto.

           SECTION 2.08. Termination and Reduction of Commitments. (a)
Termination. Unless previously terminated, (i) the Revolving Credit Commitments
shall terminate on the Maturity Date for the Revolving Credit Facility and (ii)
the Term A Commitments and the Term B Commitments shall terminate on the Closing
Date immediately after giving effect to all Borrowings which are made on such
date.

           (b) Optional Reduction. The Borrower may at any time terminate, or
from time to time reduce, the Revolving Credit Commitments; provided that (i)
each reduction of the Revolving Credit Commitments shall be in an amount that is
equal to $5,000,000 or an integral multiple of $1,000,000 in excess thereof and
(ii) the Borrower shall not terminate or reduce the Revolving Credit Commitments
to the extent that, after giving effect to any concurrent prepayment of the
Revolving Loans in accordance with Section 2.11, the Revolving Credit Exposures
would exceed the Revolving Credit Commitments as so terminated or reduced.

           (c) The Borrower shall notify the Administrative Agent of any
election to terminate or reduce the Revolving Credit Commitments under paragraph
(b) of this Section 2.08 at least three Business Days prior to the effective
date of such termination or reduction specifying such election and the effective
date thereof. Promptly following receipt of any notice, the Administrative Agent
shall advise the Revolving Lenders of the contents thereof. Each notice
delivered by the Borrower pursuant to this Section 2.08 shall be irrevocable;
provided that a notice of termination of the Revolving Credit Commitments
described in paragraph (b) of this Section 2.08 delivered by the Borrower may
state that such notice is conditioned upon the effectiveness of other credit
facilities, in which case such notice may be revoked by the Borrower (by notice
to the Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied. Any termination or reduction of the Revolving Credit
Commitments shall be permanent. Each reduction of the Revolving Credit
Commitments shall be made ratably among the Revolving Lenders in accordance with
their respective Revolving Credit Commitments.

           SECTION 2.09. Repayment of Loans; Evidence of Debt. (a) The Borrower
hereby unconditionally promises to pay:

           (i) in respect of Revolving Loans, to the Administrative Agent for
     the account of each Revolving Lender, the then unpaid principal amount of
     each Revolving Loan on Maturity Date for the Revolving Credit Facility;

                                      -33-

<PAGE>

          (ii)  in respect of Term A Loans, to the Administrative Agent for the
     account of each Term A Lender, in consecutive quarterly installments, in
     the applicable amount determined as a percentage of the aggregate Term A
     Loans outstanding immediately following the Closing Date, as set forth
     below, on the last day of each of March, June, September and December, the
     first payment to be made December 31, 2003, to be applied against the Term
     A Loans with respect to the Type and, if applicable, the Interest Period as
     the Borrower shall elect, but subject to Section 2.15:

                    Installments  Percentage Amount of each Term A

                 ==================================================

          (iii) in respect of Term B Loans, to the Administrative Agent for the
     account of each Term B Lender, in consecutive quarterly installments, in
     the applicable amount determined as a percentage of the aggregate Term B
     Loans outstanding immediately following the Closing Date set forth below,
     on the last day of each of March, June, September and December, the first
     payment to be made December 31, 2003, to be applied against the Term B
     Loans with respect to the Type and, if applicable, the Interest Period as
     the Borrower shall elect, but subject to Section 2.15:

                    Installments  Percentage Amount of each Term B

                         27                  93.5%; and
                 ===================================================

          (iv)  in respect of Swingline Loans, to the Swingline Lenders the then
     unpaid principal amount of each Swingline Loan made by them from the
     proceeds of a Revolving Borrowing or otherwise on the earlier of the
     Maturity Date for the Revolving Credit Facility and the first date after
     such Swingline Loan is made that is the 15th or last day of a calendar
     month and is at least one Business Day after such Swingline Loan is made;
     provided, that on each date a Revolving Borrowing is made, the Borrower
     shall repay all Swingline Loans then outstanding.

           (b)  Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the Obligations of the Borrower to such Lender
resulting from each Loan made by such Lender, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

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

                                      -34-

<PAGE>

received by the Administrative Agent hereunder for the account of the Lenders
and each Lender's share thereof.

           (d) The entries made in the accounts maintained pursuant to
paragraphs (b) or (c) of this Section 2.09 shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the
failure of any Lender or the Administrative Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Loans in accordance with the terms of this Agreement.

           (e) Any Lender may request that the Loans of any Class made by it be
evidenced by a promissory note (each a "Promissory Note"). In such event, the
Borrower shall prepare, execute and deliver to such Lender, with respect to such
Loans, a Promissory Note payable to the order of such Lender (or, if requested
by such Lender, to such Lender and its registered assigns) and in the forms
attached as Exhibit G-1, G-2 and G-3, as applicable to such Loans. Thereafter,
such Loans of such Lender evidenced by such Promissory Note, and interest
thereon, shall at all times (including after assignment pursuant to Section
9.04) be represented by one or more Promissory Notes in such form payable to the
order of the payee named therein (or, if such Promissory Note is a registered
note, to such payee and its registered assigns).

           SECTION 2.10. Prepayment of Loans. (a) Optional Prepayment. The
Borrower shall have the right at any time and from time to time to prepay the
Term Loans or the Revolving Loans, in each case in an amount (if less than the
aggregate outstanding principal amount of such Loans) equal to $5,000,000 or an
integral amount of $1,000,000 in excess thereof (or such lesser amount of any
class of Loans as is then outstanding), subject to prior notice in accordance
with this Section 2.10 and subject to Section 2.15. The Borrower shall notify
the Administrative Agent (and, in the case of prepayment of a Swingline Loan,
each Swingline Lender thereof) by telephone (confirmed by telecopy) of any
prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing,
not later than 11:00 a.m., New York City time, three Business Days before the
date of prepayment, (ii) in the case of prepayment of an ABR Revolving Borrowing
or a Swingline Loan, not later than 12:00 noon, New York City time, on the date
of prepayment. Each such notice shall be irrevocable and shall specify the
prepayment date and the principal amount of each Borrowing or portion thereof to
be prepaid; provided that, if a notice of prepayment is given in connection with
a conditional notice of termination of the Revolving Credit Commitments as
contemplated by Section 2.08, then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with Section 2.08. Promptly
following receipt of any such notice of prepayment relating to the Term Loans,
the Administrative Agent shall advise the Term Lenders of the contents of such
notice. Each prepayment of the Term Loans shall be applied pro rata between the
then outstanding principal amounts of the Term A Loans and the Term B Loans to
reduce the future quarterly installment amounts thereof payable, respectively,
under Sections 2.09(a)(ii) and (iii) on a pro rata basis.

           (b) Mandatory Prepayments.

           (i) The Borrower shall prepay Loans, without premium or penalty, but
     subject to Section 2.15, with (A) 100% of the Net Cash Proceeds received
     from Asset Sales (other than such Net Cash Proceeds to the extent that they
     (x) arise from an Asset Sale (or a series of related Asset Sales) in an
     amount less than $10,000,000, and (y) do not exceed $25,000,000 in
     aggregate during any single fiscal year of the Borrower), provided,
     however, that the Borrower may elect to commit to reinvest such Net Cash
     Proceeds in

                                      -35-

<PAGE>

     its or any of its Subsidiaries' business within twelve months of the
     receipt of such Net Cash Proceeds (such election to be made by a written
     notice to the Administrative Agent describing such proposed reinvestment in
     reasonable detail), in which case such amounts shall be applied to repay
     the Revolving Loans then outstanding, if any, or otherwise (if none are
     outstanding) as directed by the Borrower, provided, further, that to the
     extent the Borrower does not so reinvest such proceeds within such period,
     it shall prepay, at the expiration of such twelve month period, the
     outstanding Loans in an amount equal to such non-reinvested proceeds; (B)
     if the credit rating for the Facilities is not at least BBB- and at least
     Baa3 (as respectively rated by S&P and Moody's, and in each case with a
     stable or positive outlook) at the time of receipt of such Net Cash
     Proceeds, 100% of the Net Cash Proceeds received from any issuance of
     Indebtedness of the Borrower or its Subsidiaries pursuant to Section
     6.01(B)(o) and (C) if the credit rating for the Facilities is not at least
     BBB- and at least Baa3 (as respectively rated by S&P and Moody's, and in
     each case with a stable or positive outlook at the time any such payment is
     required to be made hereunder), within 90 days after the last day of each
     fiscal year of the Borrower, an amount equal to 50% of Excess Cash Flow for
     such fiscal year provided, that, the no such payment of Excess Cash Flow
     pursuant to this clause(C) shall be required with respect to fiscal year
     2003.

           (ii)  The mandatory prepayments referred to in paragraph (i) above
     shall (except as otherwise provided therein) be applied first pro rata
     between the then outstanding principal amounts of the Term A Loans and
     (subject to paragraph (iii) below) the Term B Loans to reduce the future
     quarterly installment amounts thereof payable, respectively, under Sections
     2.09(a)(ii) and (iii) on a pro rata basis and second to outstanding
     Revolving Loans, and thereafter to cash-collateralization of outstanding
     Letters of Credit.

           (iii) With respect to any mandatory prepayment of Term Loans pursuant
     to paragraph (ii) above, any Term B Lender may, at its option, to the
     extent that Term A Loans are then outstanding, elect not to accept such
     prepayment (any Term B Lender making such election being a "Declining
     Lender") as follows: each Declining Lender shall give written notice
     thereof to the Administrative Agent not later than 10:00 a.m. New York City
     time on the Business Day preceding the date (as notified by the
     Administrative Agent) of the applicable prepayment. On such date of
     prepayment, (x) an amount equal to that portion of the Term B Loans then to
     be prepaid to the Term B Lenders (less the amount thereof that would
     otherwise be payable to Declining Lenders) shall be paid to the Term B
     Lenders that are not Declining Lenders and (y) an amount equal to that
     portion of the Term B Loans that would otherwise be payable to Declining
     Lenders shall be applied in prepayment of the Term A Loans on a pro rata
     basis as provided in paragraph (ii) above. In the event that the
     Administrative Agent has not, with respect to any mandatory prepayment,
     received a notice from a Term B Lender in accordance with this paragraph
     (iii), such Term B Lender shall be deemed to have waived its rights under
     this paragraph (iii) to decline receipt thereof.

           SECTION 2.11. Fees. (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Revolving Lender an unused
commitment fee (an "Unused Commitment Fee"), which shall accrue at the
Applicable Commitment Fee Rate on the daily amount of the excess of (i) such
Revolving Lender's Revolving Credit Commitment over (ii) such Revolving Lender's
Revolving Credit Exposure (excluding such Revolving Lender's Swingline

                                      -36-

<PAGE>

Exposure) during the period from and including the date hereof to, but
excluding, the date on which any such Revolving Credit Commitment terminates.
Accrued Unused Commitment Fees shall be payable in arrears on the last day of
March, June, September and December of each year and on the date on which the
Revolving Credit Commitments terminate, the first payment to be made September
30, 2003. All Unused Commitment Fees shall be computed on the basis of a year of
360 days and shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).

           (b) The Borrower agrees to pay (i) to the Administrative Agent for
the account of each Revolving Lender a participation fee with respect to its
participations in Letters of Credit, which shall accrue at the same Applicable
Interest Rate Margin used to determine the interest rate applicable to
Eurodollar Revolving Loans on the average daily amount of such Revolving
Lender's L/C Exposure (excluding any portion thereof attributable to
unreimbursed L/C Disbursements) during the period from and including the Closing
Date up to but excluding the later of the date on which such Revolving Lender's
Revolving Credit Commitment terminates and the date on which such Revolving
Lender ceases to have any L/C Exposure, and (ii) to the Issuing Bank a fronting
fee, which shall accrue at a rate of 0.125% per annum on the average daily
amount of the L/C Exposure (excluding any portion thereof attributable to
unreimbursed L/C Disbursements) during the period from and including the date
hereof to, but excluding, the later of the date of termination of the Revolving
Credit Commitments and the date on which there ceases to be any L/C Exposure, as
well as the Issuing Bank's standard fees with respect to the issuance,
amendment, renewal or extension of any Letter of Credit or processing of
drawings thereunder. Fronting fees accrued through and including the last day of
March, June, September and December of each year shall be payable on the third
Business Day following such last day, the first payment to be made no earlier
than September 30, 2003; provided that all such fees shall be payable on the
date on which the Revolving Credit Commitments terminate and any such fees
accruing after the date on which the Revolving Commitments terminate shall be
payable on demand. Any other fees payable to the Issuing Bank pursuant to this
paragraph shall be payable within 10 days after demand. All fees under this
Section 2.11(b) shall be computed on the basis of a year of 360 days and shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day).

           (c) The Borrower agrees to pay to the Administrative Agent, for its
own account, the fees payable to the Administrative Agent pursuant to the Fee
Letters.

           (d) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent (or to the Issuing
Bank, in the case of fees payable to it) for distribution, in the case of
facility fees and participation fees, to the Lenders. Fees paid shall not be
refundable under any circumstances.

           SECTION 2.12. Interest. (a) The Loans constituting each ABR Borrowing
(including each Swingline Loan) shall bear interest at the Alternate Base Rate
plus the Applicable Interest Margin Rate for such Loan.

           (b) Each Loan constituting each Eurodollar Borrowing shall bear
interest in the case of a Eurodollar Loan, at the Adjusted LIBO Rate for the
Interest Period in effect for such Borrowing plus the Applicable Interest Margin
Rate for such Loan.

                                      -37-

<PAGE>

           (c) Notwithstanding the foregoing, following the occurrence and
during the continuance of an Event of Default, any principal of, or interest on
any Loan or any fee or other Obligation payable by the Borrower hereunder shall
bear interest, after as well as before judgment, at a rate per annum equal to
(i) in the case of principal of any Loan, 2.0% per annum plus the rate otherwise
applicable to such Loan as provided in the preceding clauses of this Section
2.12 and (ii) in the case of any other Obligation that has become due and
payable (but is unpaid), 2.0% plus the rate applicable to ABR Loans as provided
in paragraph (a) of this Section 2.12.

           (d) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and, in the case of Revolving Loans, upon
termination of the Revolving Credit Commitments; provided that (i) interest
accrued pursuant to paragraph (c) of this Section 2.12 shall be payable on
demand, (ii) in the event of any repayment or prepayment of any Loan (other than
a prepayment of an ABR Revolving Loan prior to the end of the Availability
Period), accrued interest on the principal amount repaid or prepaid shall be
payable on the date of such repayment or prepayment and (iii) in the event of
any conversion of any Eurodollar Revolving Loan prior to the end of the current
Interest Period therefor, accrued interest on such Loan shall be payable on the
effective date of such conversion.

           (e) All interest hereunder shall be computed on the basis of a year
of 360 days, except that interest computed by reference to the Alternate Base
Rate at times when the Alternate Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day). The applicable Alternate Base Rate,
Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent,
and such determination shall be conclusive absent manifest error. The
Administrative Agent shall, at any time and from time to time upon request of
Borrower, deliver to Borrower a statement showing the quotations used by
Administrative Agent in determining any interest rate applicable to Revolving
Loans pursuant to this Agreement.

           SECTION 2.13. Alternate Rate of Interest. If prior to the
commencement of any Interest Period for a Eurodollar Borrowing:

           (a) the Administrative Agent determines in good faith (which
determination shall be conclusive absent manifest error) that adequate and
reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the
LIBO Rate, as applicable, for such Interest Period; or

           (b) the Administrative Agent is notified by the Required Lenders that
the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period
will not adequately and fairly reflect the cost to such Lender of making or
maintaining their Loans included in such Borrowing for such Interest Period;

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

                                      -38-

<PAGE>

Borrower as promptly as practicable of receipt of any notice from the Required
Lenders referred to in paragraph (b) above of this Section 2.13. Any Lender
delivering such notice shall be deemed to be an "Affected Lender" for purposes
hereof until such Lender delivers to the Administrative Agent and the Borrower a
withdrawal of such notice.

           SECTION 2.14. Increased Costs. (a) If any Change in Law shall:

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

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

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or the
Issuing Bank of participating in, issuing or maintaining any Letter of Credit or
to reduce the amount of any sum received or receivable by such Lender or the
Issuing Bank hereunder (whether of principal, interest or otherwise), then
subject to paragraphs (c) and (d) of this Section 2.14, the Borrower will pay to
such Lender or the Issuing Bank, as the case may be, such additional amount or
amounts as will compensate such Lender or the Issuing Bank, as the case may be,
for such additional costs incurred or reduction suffered.

           (b)  If any Lender or the Issuing Bank determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's or the Issuing Bank's capital or on the capital
of such Lender's or the Issuing Bank's holding company, if any, as a consequence
of this Agreement or the Loans made by, or participations in Letters of Credit
held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a
level below that which such Lender or the Issuing Bank or such Lender's or the
Issuing Bank's holding company could have achieved but for such Change in Law
(taking into consideration such Lender's or the Issuing Bank's policies and the
policies of such Lender's or the Issuing Bank's holding company with respect to
capital adequacy), then subject to paragraphs (c) and (d) of this Section 2.14,
the Borrower will pay to such Lender or the Issuing Bank, as the case may be,
such additional amount or amounts as will compensate such Lender or the Issuing
Bank or such Lender's or the Issuing Bank's holding company for any such
reduction suffered.

           (c)  A certificate of a Lender or the Issuing Bank setting forth the
amount(s) necessary to compensate such Lender or the Issuing Bank or its holding
company, as the case may be, and the basis for the calculation thereof as
specified in paragraph (a) or (b) of this Section 2.14 shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender or the Issuing Bank, as the case may be, the amount shown as due on
any such certificate within 10 days after receipt thereof.

           (d)  Failure or delay on the part of any Lender or the Issuing Bank
to demand compensation pursuant to this Section 2.14 shall not constitute a
waiver of such Lender's or the Issuing Bank's right to demand such compensation;
provided that the Borrower shall not be

                                      -39-

<PAGE>

required to compensate a Lender or the Issuing Bank pursuant to this Section
2.14 for any increased costs or reductions incurred more than 180 days prior to
the date that such Lender or the Issuing Bank, as the case may be, notifies the
Borrower of the Change in Law giving rise to such increased costs or reductions
and of such Lender's or the Issuing Bank's intention to claim compensation
therefor; provided further that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the 180-day period referred
to above shall be extended to include the period of retroactive effect thereof.

           SECTION 2.15. Break Funding Payments. In the event of (a) the payment
of any principal of any Eurodollar Loan other than on the last day of an
Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any Eurodollar Loan other than on the last day
of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Eurodollar Loan on the date specified in any notice
delivered pursuant hereto (regardless of whether such notice may be revoked
under Section 2.10(b) and is revoked in accordance therewith), or (d) the
assignment of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto as a result of a request by the Borrower pursuant to
Section 2.18, then, in any such event, the Borrower shall compensate each Lender
for the loss, cost and expense sustained by such Lender (or its Affiliates) as a
result of such event. In the case of a Eurodollar Loan, such loss, cost or
expense to any Lender shall include any loss or expense incurred by reason of
the liquidation or redeployment of deposits or other funds acquired by such
Lender to fund or maintain such Eurodollar Loan to the Borrower, but shall
exclude any loss of anticipated Applicable Interest Rate Margin that would have
accrued following such event with respect to each such Eurodollar Loan but for
the occurrence of such event. A certificate of any Lender setting forth any
amount(s) that such Lender is entitled to receive and the basis for the
calculation thereof pursuant to this Section 2.15 shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

           SECTION 2.16. Taxes. (a) Any and all payments by or on account of any
obligation of the Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions the Administrative Agent, Lender(s) or
Issuing Bank (as the case may be) receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

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

           (c) The Borrower shall indemnify the Administrative Agent, each
Lender and the Issuing Bank, within 10 days after written demand therefor, for
the full amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or
with respect to any payment by or on account of any obligation of the Borrower
hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes or

                                      -40-

<PAGE>

Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority.

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

          (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax with respect to any Indemnified Tax or Other Tax
(including by application of any treaty, the benefits of which such Lender is
entitled), with respect to payments under this Agreement shall deliver to the
Borrower (with a copy to the Administrative Agent), on or prior to the date such
Foreign Lender becomes a party to this Agreement (or designates a new lending
office) and at such other times as may be necessary in the reasonable
determination of the Borrower or Administrative Agent, (i) two original copies
of Internal Revenue Service Form W-8BEN or W-8ECI (or any successor forms),
properly completed and duly executed by such Lender, and such other
documentation required under the Code to establish that such Lender is not
subject to deduction or withholding of United States federal income tax with
respect to any payments to such Lender of principal, interest, fees or other
amounts payable under this Agreement, or (ii) if such Lender is not a "bank" or
other Person described in Section 881(c)(3) of the Code and cannot deliver
either Internal Revenue Service Form W-8BEN or W-8ECI pursuant to clause (i)
above of this Section 2.16(e), a Certificate of Non-Bank Status together with
two original copies of Internal Revenue Service Form W-8 (or any successor
form), properly completed and duly executed by such Lender, and such other
documentation required under the Code to establish that such Lender is not
subject to deduction or withholding of United States federal income tax with
respect to any payments to such Lender of interest payable under this Agreement.
Each Lender that is not a Foreign Lender shall deliver to the Borrower (with a
copy to the Administrative Agent) two duly completed copies of United States
Internal Revenue Form W-9 (or applicable successor form) unless it establishes
to the satisfaction of the Borrower that the Lender is otherwise eligible for an
exemption from backup withholding tax or other applicable withholding tax. Each
Lender hereby agrees, from time to time after the initial delivery by such
Lender of such forms, certificates or other evidence required to be provided
pursuant to the first two sentences of this Section 2.16(e), whenever a lapse in
time or change in circumstances renders such forms, certificates or other
evidence obsolete or inaccurate in any material respect, that such Lender shall
promptly deliver to Administrative Agent for transmission to the Borrower two
new original copies of Internal Revenue Service Form W-8BEN, W-8ECI or W-9 or a
Certificate of Non-Bank Status and two original copies of Internal Revenue
Service Form W-8, as the case may be, properly completed and duly executed by
such Lender, and such other documentation required under the Code to confirm or
establish that such Lender is not subject to deduction or withholding of United
States federal income tax with respect to payments to such Lender under this
Agreement, or notify Administrative Agent and the Borrower of its inability to
deliver any such forms, certificates or other evidence. Notwithstanding any
other provision of this Section 2.16(e), a Foreign Lender shall not be required
to deliver any form pursuant to this Section 2.16(e) that such Foreign Lender is
not legally able to deliver.

          (f) If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund of any Indemnified Taxes or Other
Taxes as to which it has been

                                      -41-

<PAGE>

indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section 2.16, it shall promptly notify the
Borrower of such refund and promptly pay over such refund to the Borrower (but
only to the extent of indemnity payments made, or additional amounts paid, by
the Borrower under this Section 2.16 with respect to the Taxes or Other Taxes
giving rise to such refund), net of all out-of-pocket expenses of the
Administrative Agent or such Lender 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 Lender, 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 Lender in the event the
Administrative Agent or such Lender is required to repay such refund to such
Governmental Authority. This Section shall not be construed to require the
Administrative Agent or any Lender 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.

          SECTION 2.17. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest, fees or reimbursement of L/C
Disbursements, or of amounts payable under Section 2.14, 2.15 or 2.16, or
otherwise) prior to 12:00 noon, New York City time, on the date when due, in
immediately available funds, without set-off or counterclaim. Any amounts
received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at 270 Park Avenue, New
York, New York, except payments to be made directly to the Issuing Bank or
Swingline Lenders as expressly provided herein and except that payments pursuant
to Sections 2.14, 2.15, 2.16, and 9.03 shall be made directly to the Persons
entitled thereto. The Administrative Agent shall distribute any such payments
received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof. If any payment hereunder shall be due on a
day that is not a Business Day, the date for payment shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

          (b) Except for payments and other amounts received by the
Administrative Agent and applied in accordance with the provisions of paragraph
(f) of this Section 2.17, all payments and other amounts received by and
available to the Administrative Agent to pay fully all amounts of principal,
unreimbursed L/C Disbursements, interest, fees and other Obligations then due
hereunder shall be applied (i) first, towards payment of interest and fees then
due hereunder, ratably among the parties entitled thereto in accordance with the
amounts of interest and fees then due to such parties, (ii) second, towards
payment of principal and unreimbursed L/C Disbursements then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal and unreimbursed L/C Disbursements then due to such parties and (iii)
third towards payment of any other Obligations then due hereunder, ratably among
the parties entitled thereto in accordance with the amounts of Obligations then
due to such parties.

          (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans or participations in L/C Disbursements or Swingline
Loans resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its Loans and participations in L/C

                                      -42-

<PAGE>

Disbursements and Swingline Loans and accrued interest thereon than the
proportion received by any other Lender, then the Lender receiving such greater
proportion shall purchase (for cash at face value) participations in the Loans
and participations in L/C Disbursements and Swingline Loans of other Lenders to
the extent necessary so that the benefit of all such payments shall be shared by
the Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and participations in L/C
Disbursements and Swingline Loans; provided that (i) if any such participations
are purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph (c) of this Section 2.17 shall not be construed to
apply to any payment made by the Borrower pursuant to and in accordance with the
express terms of this Agreement or any payment obtained by a Lender as
consideration for the assignment of or sale of a participation in any of its
Loans or participations in L/C Disbursements to any assignee or participant,
other than to the Borrower or any Subsidiary or Affiliate thereof (as to which
the provisions of this paragraph (c) of this of this Section 2.17 shall apply).
The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the
Borrower rights of set-off and counterclaim with respect to such participation
as fully as if such Lender were a direct creditor of the Borrower in the amount
of such participation.

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

          (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.04(c), 2.05(d) or (e), 2.06(b) or 2.17(d), then the
Administrative Agent may, in its discretion (notwithstanding any contrary
provision hereof), apply any amounts thereafter received by the Administrative
Agent for the account of such Lender to satisfy such Lender's obligations under
such Sections until all such unsatisfied obligations are fully paid.

          (f) The Borrower hereby irrevocably waives the right to direct the
application of any and all payments in respect of the Secured Obligations and
any proceeds of Collateral after the occurrence and during the continuance of an
Event of Default and agrees that, notwithstanding the provisions of Sections
2.10(b) and 2.17(b), the Administrative Agent may, and, upon either (A) the
written direction of the Required Lenders or (B) the acceleration of the
Obligations pursuant to Article VII, shall apply all payments in respect of any
Secured Obligations and all proceeds of Collateral in the following order:

          (i)    first, to pay interest on and then principal of any portion of
     the Revolving Loans that the Administrative Agent may have advanced on
     behalf of any Lender for

                                      -43-

<PAGE>

     which the Administrative Agent has not then been reimbursed by such Lender
     or the Borrower;

          (ii)   second, to pay interest on and then principal of any Swingline
     Loan;

          (iii)  third, to pay Obligations in respect of any expense
     reimbursements or indemnities then due to the Administrative Agent and the
     Co-Syndication Agents;

          (iv)   fourth, to pay Obligations in respect of any expense
     reimbursements or indemnities then due to the Lenders and the Issuing Bank;

          (v)    fifth, to pay Obligations in respect of any fees then due to
     the Administrative Agent and the Co-Syndication Agents, the Lenders and the
     Issuing Bank;

          (vi)   sixth, to pay interest then due and payable in respect of the
     Loans and L/C Disbursements;

          (vii)  seventh, to pay or prepay principal amounts on the Loans and
     L/C Disbursements, to provide cash collateral for outstanding undrawn
     Letters of Credit in the manner described in Section 2.05(j) and to pay
     Hedging Obligations owing to any Hedging Creditor and Cash Management
     Obligations owing to any Secured Party, ratably to the aggregate principal
     amount of such Loans, L/C Disbursements and undrawn Letters of Credit,
     Hedging Obligations and Cash Management Obligations; and

          (viii) eighth, to the ratable payment of all other Secured
     Obligations;

provided, however, that if sufficient funds are not available to fund all
payments to be made in respect of any Secured Obligation described in any of
clauses (i) through (viii) above, the available funds being applied with respect
to any such Secured Obligation (unless otherwise specified in such clause) shall
be allocated to the payment of such Secured Obligations ratably, based on the
proportion of the Administrative Agent's, each Co-Syndication Agent's and each
Lender's, each Hedging Creditor's, the Issuing Bank's and each other holder of a
Secured Obligation's interest in the aggregate outstanding Secured Obligations
described in such clauses. The order of priority set forth in clauses (i)
through (viii) above may at any time and from time to time be changed by the
agreement of the Required Lenders and, to the extent that each Class is not
equally affected thereby, with the additional agreement of the Required Class
Lenders with respect to each affected Class, without necessity of notice to or
consent of or approval by the Borrower, any Secured Party that is not a Lender
or Issuing Bank or by any other Person that is not a Lender or Issuing Bank. The
order of priority set forth in clauses (i) through (v) above may be changed only
with the prior written consent of the Administrative Agent in addition to that
of the Required Lenders. The order of priority set forth in clauses (i) and (ii)
above may be changed only with the prior written consent of the Swingline
Lenders in addition to that of the Required Lenders and the Administrative
Agent.

          SECTION 2.18. Mitigation Obligations; Replacement of Lenders. (a) If
any Lender requests compensation under Section 2.14, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.16 or as a result
of any Lender's assignment to an Affiliate of such Lender or an Approved Fund
pursuant to Section 9.04(b), or if any Lender is an Affected Lender, then

                                      -44-

<PAGE>

such Lender shall, upon the request of the Borrower, use reasonable efforts to
designate a different lending office for funding or booking its Loans or Letters
of Credit hereunder or to assign its rights and obligations hereunder to another
of its offices, branches or Affiliates, if such designation or assignment (i)
would be reasonably expected to eliminate or reduce amounts payable pursuant to
Sections 2.14 or 2.16 in the future or result in such Lender or its assignee, as
applicable, not being an Affected Lender; and (ii) would not subject such Lender
to any unreimbursed cost or expense and would not otherwise be disadvantageous
to such Lender. The Borrower hereby agrees to pay all reasonable costs and
expenses incurred by any Lender in connection with any such designation or
assignment.

          (b) If (i) any Lender requests compensation under Section 2.14, or if
the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16 or
as a result of any Lender's assignment to an Affiliate of such Lender or an
Approved Fund pursuant to Section 9.04(b), or (ii) any Lender is a Non-Funding
Lender or (iii) any Lender has failed to consent to a proposed amendment,
waiver, discharge or termination which pursuant to the terms of this agreement
or any other Loan Document requires the consent of all of the Lenders or of any
Class of Lenders and with respect to which the Required Lenders or the Required
Class Lenders, as applicable, shall have granted their consent (provided that
for the purposes of this clause (iii), each of the percentages specified in the
definitions of "Required Lenders" and "Required Class Lenders" shall be deemed,
in each such case, to be increased to 75% and each such definition shall be
construed accordingly), then the Borrower may, at its sole expense and effort
(other than in the case of a default by a non-funding Lender, in which case such
Lender shall be responsible for all reasonable out-of-pocket costs of the
Borrower), upon notice to such Lender and the Administrative Agent, (x) prepay
such Lender in full or (y) require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement to
an assignee selected by the Borrower and approved by the Administrative Agent
(such approval not be unreasonably withheld or delayed) in accordance with
Section 9.04, that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) such Lender
shall have received payment of an amount equal to the outstanding principal of
its Loans and participations in L/C Disbursements and Swingline Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrower (in the case of all other amounts) and (ii)
in the case of any such assignment resulting from a claim for compensation under
Section 2.14 or payments required to be made pursuant to Section 2.16, such
assignment would be reasonably expected to result in a reduction in such
compensation or payments. A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

                                   ARTICLE III
                         Representations and Warranties

          The Borrower represents and warrants to the Lenders that:

          SECTION 3.01. Organization; Powers. Each of the Borrower and its
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, has all requisite power and
authority to carry on its business as

<PAGE>

now conducted and is qualified to do business in, and is in good standing in,
every jurisdiction where such qualification is required except, in each case,
where the failure to do so, individually or in the aggregate, has not resulted,
and would not reasonably be expected to result, in a Material Adverse Effect.
Each Subsidiary of the Borrower is and shall be directly-owned by the Borrower,
except (i) Subsidiaries, all the outstanding capital stock of which is subject
to a first priority perfected pledge in favor of the Administrative Agent to
secure the Secured Obligations and (ii) certain inactive Subsidiaries holding de
minimis assets as set forth on Schedule 3.01. As of the date hereof, the
Borrower has no Subsidiaries other than those Persons listed on Schedule 3.01.

          SECTION 3.02. Authorization; Enforceability. The Loan Documents and
the transactions contemplated thereby are within the Borrower's corporate powers
and have been duly authorized by all necessary corporate and, if required,
stockholder action on the part of the Borrower. Each of this Agreement and the
other Loan Documents has been duly executed and delivered by the Borrower and
constitutes a legal, valid and binding obligation of the Borrower, enforceable
against the Borrower in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights generally and subject to general principles of equity,
regardless of whether considered in a proceeding in equity or at law.

          SECTION 3.03. Governmental Approvals; No Conflicts; Ranking.

          (a) The Transactions and the Related Documents:

          (i) do not require any consent or approval of, registration or filing
     with, or any other action by, any Governmental Authority, except such as
     have been obtained or made and are in full force and effect and except as
     have not resulted, and would not reasonably be expected to result, in a
     Material Adverse Effect;

          (ii) do not violate any applicable law (including ERISA and
     Environmental Laws) or regulation or any order of any Governmental
     Authority except as have not resulted, and would not reasonably be expected
     to result, in a Material Adverse Effect;

          (iii) do not violate the charter, by-laws or other organizational
     documents of the Borrower or any of its Subsidiaries;

          (iv) will not violate any indenture, agreement or other instrument
     binding upon the Borrower or any of its Subsidiaries or its assets, or give
     rise to a right thereunder to require any payment to be made by the
     Borrower or any of its Subsidiaries except as has not resulted, and would
     not reasonably be expected to result, in a Material Adverse Effect; and

          (v) will not result in the creation or imposition of any Lien (except
     any Lien permitted by Section 6.02) on any asset of the Borrower or any of
     its Subsidiaries.

          (b) Each Loan ranks pari passu in right of payment with each other
     Loan (except as provided herein) and, for bankruptcy purposes, with all
     other unsubordinated, non-credit enhanced and unsecured Indebtedness of the
     Borrower.

condition (financial or otherwise) of the Borrower and its Subsidiaries, taken

          SECTION 3.05. Properties; Insurance. (a) Each of the Borrower and its

purposes.

licensed or otherwise has the right to use, all trademarks, trade names,

Subsidiaries does not and will not violate the rights of any other Person,
except for any such violations that, individually or in the aggregate, has not
resulted, and would not reasonably be expected to result, in a Material Adverse
Effect. No claim is pending and, to the knowledge of the Executive Officers, no
claim has been asserted by any person challenging or questioning the use of any
such trademark, trade name, copyright, patent or other intellectual property or
proprietary rights except as has not resulted, and would not reasonably be
expected to result, in a Material Adverse Effect.

          (c) The Borrower maintains, with financially sound and reputable
insurance companies, on its own behalf and on behalf of its Subsidiaries,
insurance in such amounts and against such risks as are customarily maintained
by companies engaged in the same or similar businesses operating in the same or
similar locations.

actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Executive Officers,
threatened against or affecting the Borrower or any of its Subsidiaries that (i)

aggregate, to result in a Material Adverse Effect or (y) seek to enjoin, unwind
or otherwise materially and adversely affect this Agreement or the Transactions.

          SECTION 3.07. Compliance with Laws and Agreements; No Default. (a)
Each of the Borrower and its Subsidiaries is in compliance with all laws,
regulations and orders of any Governmental Authority applicable to it or its
property and all indentures, agreements and other instruments binding upon it or
its property, except where the failure to do so, individually or in the
aggregate, has not resulted, and would not reasonably be expected to result, in

set aside on its books reserves to the extent required under GAAP or (b) to the
extent that the failure to do so has not resulted, and would not reasonably be
expected to result, in a Material Adverse Effect.

          SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, has resulted, or could
reasonably be expected to result, in a Material Adverse Effect. The Borrower and
its ERISA Affiliates have fulfilled their respective obligations under the
minimum funding standards of ERISA and the Code with respect to each Plan and
are in compliance in all material respects with the presently applicable
provisions of ERISA and the Code and have not incurred any liability to the PBGC
(other than to make contributions, pay annual PBGC premiums or pay out benefits

Separation and Transition Agreements that will give effect to the Spin-Off are
substantially in the form reviewed prior to the date hereof by the Joint Lead
Arrangers, and none of the terms or conditions of such agreements shall be

all agreements (including those related to Medicare and Medicaid), instruments
(including in the Spin-Off Registration Statement, the Notes Indenture and the

to the conduct of its business (including agreements with Merck, including those
to be entered into in connection with the Spin-Off described in the Spin-Off
Registration Statement) except for failures to do so which, individually or
collectively, would not reasonably be expected to, result in a Material Adverse
Effect; provided that the foregoing shall not prohibit any transaction permitted
under Section 6.03.

          SECTION 5.04. Payment of Obligations. The Borrower will, and will
cause each of its Subsidiaries to, pay its obligations, including Tax
liabilities, before the same shall become delinquent or in default, that, if not

respect thereto to the extent required under GAAP.

          SECTION 5.05. Maintenance of Properties; Insurance. The Borrower will,
and will cause each of its Subsidiaries to, keep and maintain all property
material to the conduct of their businesses in good working order and condition,

with financially sound and reputable insurance companies, directly, or through
Merck, on the Borrower's own behalf and on behalf of its Subsidiaries, insurance
in such amounts and against such risks as are customarily maintained by
companies engaged in the same or similar businesses operating in the same or
similar locations.

accountants, shall be an accounting firm of nationally recognized standing which
is reasonably acceptable to the Borrower), upon reasonable prior notice and
without causing material disruption, and at the expense of the Administrative
Agent or such Lender, as applicable, to visit and inspect its properties, to
examine and make extracts from its books and records, and to discuss its
affairs, finances and condition with its officers and

                                      -55-

independent accountants, all at such reasonable times and as often as reasonably
requested (subject to confidentiality obligations of the Borrower or its
Subsidiaries).

          SECTION 5.07. Compliance with Laws and Agreements. The Borrower will,
and will cause each of its Subsidiaries to, comply with all laws (including
ERISA and Environmental Law), rules, regulations and orders of any Governmental
Authority applicable to it or its property (including the Separation and
Transition Agreement and any other agreements to be entered into in connection
with the Spin-Off as described in the Spin-Off Registration Statement), except
where the failure to do so, individually or in the aggregate, would not
reasonably be expected to, result in a Material Adverse Effect.

          SECTION 5.08. Spin-Off. The Spin-Off will be completed on terms and
conditions substantially as described in Schedule 3.12. The underwriting and
exchange agreements giving effect to the Spin-Off and the Separation and
Transition Agreements have been or will be executed and delivered substantially
as described in Schedule 3.12 and in the form reviewed prior to the Closing Date
by the Joint Lead Arrangers and in full force and effect without any defaults or
breaches thereunder that would cause any of the conditions to closing of the
Spin-Off not to be satisfied, and none of the terms or conditions of such
documentation shall be amended, waived or otherwise modified in a manner that
would, in the reasonable judgment of the Joint Lead Arrangers, be materially
adverse to the Lenders without the Joint Lead Arrangers' consent, provided,
however, that such documentation may be amended or modified, or (in the case of
the Managed Care Agreement) replaced with one or more other agreements which,
taken as a whole, are not materially less favorable to the Borrower, to the
extent that a Material Adverse Effect would not reasonably be expected to,
result therefrom.

          SECTION 5.09. Use of Proceeds and Letters of Credit. The proceeds of
the Term Loan shall only, and up to $50,000,000 of the Revolving Loans may, be
used, together with proceeds from the Notes Offering, initial proceeds of the
Securitization and available cash (including from settlement of an intercompany
payable owed to the Borrower by Merck), to pay the Merck Dividend. The proceeds
of the Revolving Loans shall (except as provided above) be only used for the
Borrower's general corporate and working capital purposes. No part of the
proceeds of the Loans shall be used in violation of the restrictions set forth
in Sections 3.13 and 6.04(p). Letters of Credit will be issued only to support
the Borrower's general corporate and working capital purposes.

          SECTION 5.10. Additional Collateral. To the extent not delivered to
the Administrative Agent on or before the Closing Date, the Borrower agrees to
(or cause each of its applicable Subsidiaries to) do promptly each of the
following:

          (a)  execute and deliver to the Administrative Agent such supplements,
and amendments to the Pledge Agreement (or, in the case of Equity Interests of
any Subsidiary of the Borrower that is not a Domestic Subsidiary, appropriate
foreign law pledge agreements) as the Administrative Agent deems necessary or
advisable in order to grant to the Administrative Agent, for the benefit of the
Secured Parties, a perfected first priority security interest in the Equity
Interests of such Subsidiary that are owned by the Borrower (and of any
Subsidiary that is not directly owned by the Borrower as contemplated in Section
3.01(i)) and requested to be pledged by the Administrative Agent; provided,
however, that, unless otherwise agreed by the Borrower and the Administrative
Agent, in no event shall such the Borrower be required to pledge in excess of
66% of the outstanding voting stock of any direct Subsidiary of the Borrower
that is not a

                                      -56-

<PAGE>

Domestic Subsidiary or to pledge the Equity Interests of any Insurance
Subsidiary or the Securitization SPV.

representing such Equity Interests, together with in the case of such
certificated Equity Interests, undated stock powers endorsed in blank executed
and delivered by an officer of the Borrower; and

          (c)  if requested by the Administrative Agent, deliver to the
Administrative Agent legal opinions relating to the matters described above,
which opinions shall be in form and substance, and from counsel, reasonably
satisfactory to the Administrative Agent.

the reporting date with respect thereto, as if they had occurred on the first
day of the applicable reference period or as of the last day of the applicable
quarter, as the case may be.

connection with this Agreement or any amendment or modification hereof or waiver
hereunder, shall prove to have been incorrect in any material respect (except
that, to the extent any such representation or warranty is qualified by
materiality or Material Adverse Effect, such representation or warranty shall
prove to have been incorrect in any respect) when made or deemed made;

then, and in every such event (other than an event with respect to the Borrower

thereafter during the continuance of such event, the Administrative Agent may,
and at the request of the Required Lenders shall, by notice to the Borrower,
take either or both of the following actions, at the same or different times:
(i) terminate the Lenders' Total Commitments, and thereupon such Total
Commitments shall terminate immediately, and (ii) declare the Loans then
outstanding to be due and payable in whole (or in part, in which case any
principal not so declared to be due and payable may thereafter be declared to be
due and payable), and thereupon the principal of the Loans so declared to be due
and payable, together with accrued interest thereon and all fees and other
Obligations of the Borrower accrued hereunder, shall become due and payable
immediately, without presentment, demand, protest or other notice of any kind,
all of which are hereby waived by the Borrower; and in case of any event with
respect to the Borrower described in paragraph (i) or (j) of this Article VII,
the Lenders' Total Commitments shall automatically terminate and the principal
of the Loans then outstanding, together with accrued interest thereon and all
fees and other Obligations of the Borrower accrued hereunder, shall
automatically become due and payable, without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by the Borrower. In

any remedies provided for by the Collateral Documents in accordance with the
terms thereof or any other remedies provided by applicable law.

                                  ARTICLE VIII
                            The Administrative Agent

           (a) Each of the Lenders and the Issuing Bank hereby irrevocably
appoints the Administrative Agent as its agent and authorizes the Administrative
Agent to take such actions on its behalf and to exercise such powers as are
delegated to the Administrative Agent by the terms hereof, together with such
actions and powers as are reasonably incidental thereto. Without limiting the
foregoing, each Lender and the Issuing Bank hereby authorize the Administrative
Agent to execute and deliver, and to perform its obligations under, each of the
Loan Documents to which the Administrative Agent is a party, to exercise all
rights, powers and remedies that the Administrative Agent may have under such
Loan Documents and, in the case of the Collateral Documents, to act as agent for
the Lenders, the Issuing Bank and the other Secured Parties under such
Collateral Documents.

           (b) The bank serving as the Administrative Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and
may exercise the same as though it were not the Administrative Agent, and such
bank and its Affiliates may accept deposits

                                      -70-

<PAGE>

from, lend money to and generally engage in any kind of business with the
Borrower or any Subsidiary or other Affiliate thereof as if it were not the
Administrative Agent hereunder.

          (c) The Administrative Agent shall not have any duties or obligations
except those expressly set forth herein. Without limiting the generality of the
foregoing, (i) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default has occurred and is
continuing, (ii) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing as directed by the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.02), and (iii) except as expressly set
forth herein, the Administrative Agent shall not have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to the
Borrower or any of its Subsidiaries that is communicated to or obtained by the
bank serving as Administrative Agent or any of its Affiliates in any capacity.
The Administrative Agent shall not be liable for any action taken or not taken
by it with the consent or at the request of the Required Lenders (or such other
number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.02) or in the absence of its own gross
negligence or willful misconduct. The Administrative Agent shall be deemed not
to have knowledge of any Default unless and until written notice thereof is
given to the Administrative Agent by the Borrower or a Lender, and the
Administrative Agent shall not be responsible for or have any duty to ascertain
or inquire into (v) any statement, warranty or representation made in or in
connection with this Agreement, (w) the contents of any certificate, report or
other document delivered hereunder or in connection herewith, (x) the
performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein, (y) the validity, enforceability, effectiveness or
genuineness of this Agreement or any other agreement, instrument or document, or
(z) the satisfaction of any condition set forth in Article IV or elsewhere
herein, other than to confirm receipt of items expressly required to be
delivered to the Administrative Agent.

          (d) The Administrative Agent shall be entitled to rely upon, and shall
not incur any liability for relying upon, any notice, request, certificate,
consent, statement, instrument, document or other writing believed by it to be
genuine and to have been signed or sent by the proper Person. The Administrative
Agent also may rely upon any statement made to it orally or by telephone and
believed by it to be made by the proper Person, and shall not incur any
liability for relying thereon. The Administrative Agent may consult with legal
counsel (who may be counsel for the Borrower), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not
taken by it in accordance with the advice of any such counsel, accountants or
experts.

          (e) The Administrative Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the
preceding paragraphs shall apply to any such sub-agent and to the Related
Parties of the Administrative Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

                                      -71-

<PAGE>

          (f) Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this paragraph, the Administrative Agent may
resign at any time by notifying the Lenders, the Issuing Bank and the Borrower.
Upon any such resignation, the Required Lenders shall have the right to appoint
a successor, subject to the approval of the Borrower not to be unreasonably
withheld so long as the Borrower is not then in Default. If no successor shall
have been so appointed by the Required Lenders and shall have accepted such
appointment within 30 days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may, on behalf of the
Lenders and the Issuing Bank, appoint a successor Administrative Agent, subject
to the approval of the Borrower not to be unreasonably withheld so long as the
Borrower is not then in Default, which shall be a bank with an office in New
York, New York, or an Affiliate of any such bank. Upon the acceptance of its
appointment as Administrative Agent hereunder by a successor, such successor
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder. The fees
payable by the Borrower to a successor Administrative Agent shall be the same as
those payable to its predecessor unless otherwise agreed between the Borrower
and such successor. After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 9.03 shall continue in effect for the
benefit of such retiring Administrative Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as Administrative Agent.

          (g) Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

          (h) Each Lender and the Issuing Bank agree that any action taken by
the Administrative Agent or the Required Lenders (or, where required by the
express terms of this Agreement, a greater proportion of the Lenders) in
accordance with the provisions of this Agreement or of the other Loan Documents,
and the exercise by the Administrative Agent or the Required Lenders (or, where
so required, such greater proportion) of the powers set forth herein or therein,
together with such other powers as are reasonably incidental thereto, shall be
authorized and binding upon all of the Lenders, the Issuing Bank and other
Secured Parties. Without limiting the generality of the foregoing, the
Administrative Agent shall have the sole and exclusive right and authority to
(i) act as the disbursing and collecting agent for the Lenders and the Issuing
Bank with respect to all payments and collections arising in connection herewith
and with the Collateral Documents, (ii) execute and deliver each Collateral
Document and accept delivery of each such agreement delivered by the Borrower or
any of its Subsidiaries, (iii) act as collateral agent for the Lenders, the
Issuing Bank and the other Secured Parties for purposes of the perfection of all
security interests and Liens created by such agreements and all other purposes
stated therein, provided, however, that the Administrative Agent hereby
appoints, authorizes and directs each Lender and the Issuing Bank to act as
collateral sub-agent for the Administrative Agent, the Lenders and the Issuing
Bank for purposes of the perfection of all security interests and Liens with
respect to the Borrower's and its Subsidiaries' respective Deposit Accounts
maintained with, and cash and Cash Equivalents held by, such Lender or the

                                      -72-

<PAGE>

Issuing Bank, (iv) manage, supervise and otherwise deal with the Collateral, (v)
take such action as is necessary or desirable to maintain the perfection and
priority of the security interests and Liens created or purported to be created
by the Collateral Documents and (vi) except as may be otherwise specifically
restricted by the terms hereof or of any other Loan Document, exercise all
remedies given to the Administrative Agent, the Lenders, the Issuing Bank and
the other Secured Parties with respect to the Collateral under the Loan
Documents relating thereto, applicable law or otherwise.

          (i) Each of the Lenders and the Issuing Bank hereby direct, in
accordance with the terms hereof, the Administrative Agent to release (or, in
the case of clause Error! Reference source not found. Error! Reference source
not found., release or subordinate) any Lien held by the Administrative Agent
for the benefit of the Lenders and the Issuing Bank against any of the
following:

                  (i)   all of the Collateral, upon termination of the
     Commitments and payment and satisfaction in full of all Loans, L/C Exposure
     and all other Obligations that the Administrative Agent has been notified
     in writing are then due and payable (and, in respect of contingent L/C
     Exposure, with respect to which cash collateral has been deposited or a
     back-up letter of credit has been issued, in either case on terms
     satisfactory to the Administrative Agent and the Issuing Bank);

                  (ii)  any assets that are subject to a Lien permitted by
     Section 6.01(B)(k); and

                  (iii) any part of the Collateral sold or disposed of by the
     Borrower if such sale or disposition is permitted by this Agreement (or
     permitted pursuant to a waiver or consent of a transaction otherwise
     prohibited by this Agreement).

          (j) Each of the Lenders and the Issuing Bank hereby direct the
Administrative Agent to execute and deliver or file such termination and partial
release statements and do such other things as are necessary to release Liens to
be released pursuant to this Article VIII promptly upon the effectiveness of any
such release.

          (k) Each Joint Lead Arranger and each Co-Syndication Agent (except in
its capacity as a Lender) shall not have, and shall not by reason of being named
in this Agreement be deemed to have, any obligations under this Agreement.

                                   ARTICLE IX
                                  Miscellaneous

          (b)   Notices and other communications to the Lenders hereunder may be

pursuant to procedures approved by the Administrative Agent and financial
statements required to be furnished hereunder by the Borrower may be furnished
by means of posting to an IntraLinks site to which the Administrative Agent and
each Lender has been granted access; provided that the foregoing shall not apply
to notices pursuant to Article II unless otherwise agreed by the Administrative
Agent and the applicable Lender. The Administrative Agent or the Borrower may,
in its discretion, agree to accept notices and other communications to it
hereunder by electronic communications, and not by telecopy, pursuant to
procedures approved by it; provided that approval of such procedures may be
limited to particular notices or communications.

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

Administrative Agent, the Issuing Bank or any Lender in exercising any right or
power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent, the Issuing Bank and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,

                                      -74-

<PAGE>

and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan or issuance of a Letter of Credit shall not be
construed as a waiver of any Default, regardless of whether the Administrative
Agent, any Lender or the Issuing Bank may have had notice or knowledge of such
Default at the time.

          (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders or by the Borrower and the
Administrative Agent with the consent of the Required Lenders; provided that no
such agreement shall (i) increase any Commitment of any Lender without the
written consent of such Lender, (ii) increase the maximum aggregate amount of
Swing Line Loans or L/C Exposure permitted to be outstanding hereunder without
the written consent of the Required Class Lenders under the Revolving Credit
Facility and (in the case of such increase to the maximum aggregate amount of
L/C Exposure) the Issuing Bank, (iii) reduce the principal amount of any Loan or
L/C Disbursement or reduce the rate of interest thereon (other than a waiver of
default interest arising under Section 2.12(c)), or reduce any fees payable
hereunder, without the written consent of each Lender affected thereby, (iv)
postpone the Maturity Date or the scheduled date of payment of any interest on
any Loan, or any fees payable hereunder, or reduce the amount of, waive or
excuse any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (v)
change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing
of payments required thereby, without the written consent of each Lender
affected thereby, (vi) release all or substantially all of the Collateral,
change any of the provisions of this Section or the definition of "Required
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder, without the written consent of
each Lender; provided further that no such agreement shall amend, modify or
otherwise affect the rights or duties of the Administrative Agent, the Issuing
Bank or the Swingline Lenders hereunder without the prior written consent of the
Administrative Agent, the Issuing Bank or the Swingline Lenders, as the case may
be, or (vii) change the allocation between any optional or mandatory prepayments
of Term Loans and Revolving Loans, without the written consent of the applicable
Required Class Lenders affected thereby; provided, further, that the
Administrative Agent and the Borrower may, with the consent of the other, amend,
modify or supplement this Agreement to cure any ambiguity, typographical error,
defect or inconsistency, so long as such amendment, modification or supplement
does not adversely affect the rights of any Lender or any Issuing Bank.

          SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The Borrower
shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent, the Joint Lead Arrangers, the Co-Syndication Agents and

and administration of this Agreement or any amendments, waivers, modifications,
waivers or extensions (including amendments, waivers, modifications or
extensions proposed by the Borrower) of the provisions hereof (whether or not
the transactions contemplated hereby or thereby shall be consummated), provided
that the Borrower shall not be required (except in connection with the primary
syndication of Term B

Administrative Agent, the Joint Lead Arrangers, the Co-Syndication Agents, any
Lender or any other Related Parties incurred in connection with an assignment or
participation of any rights or obligations of a Lender hereunder unless
initiated by the Borrower under Section 2.19(b) other than as a result of a
default by the Lender; and (ii) all reasonable out-of-pocket expenses incurred
by the Issuing Bank (without duplication of amounts described in Section 2.12)
in connection with the issuance, amendment, waiver, modification, extension or
renewal (including proposed amendments, waivers, modifications, extensions or
renewals) of any Letter of Credit or any demand for payment thereunder and (iii)
all out-of-pocket expenses incurred by the Administrative Agent, the Issuing
Bank, any Lender, the Joint Lead Arrangers or the Co-Syndication Agents,

the Co-Syndication Agents, in connection with the enforcement or protection of
its rights under and in connection with this Agreement or the Loan Documents,
including its rights under this Section or in connection with the Loans made or
Letters of Credit issued hereunder, including all such out-of-pocket expenses
incurred in connection with any workout proceedings, enforcement costs and
documentary taxes or negotiations in respect of such Loans or Letters of Credit.

          (b) The Borrower shall indemnify the Administrative Agent, the Issuing
Bank, each Lender, the Joint Lead Arrangers and the Co-Syndication Agents, and
each Related Party of any of the foregoing Persons (each such Person being
called an "Indemnitee") against, and hold each Indemnitee harmless from, any and
all reasonable out-of pocket costs, losses, claims, damages, liabilities and
related expenses, including the reasonable fees, charges and disbursements of
any counsel for any Indemnitee, incurred by or asserted against any Indemnitee
arising out of, in connection with any actual or threatened third-party claim,
litigation, investigation or proceeding (a "Third-Party Claim"), whether based
on contract, tort or any other theory and regardless of whether any Indemnitee
is a party thereto, relating to (i) the execution or delivery of this Agreement
or any agreement or instrument contemplated hereby, the performance by the
parties hereto of their respective obligations hereunder or the consummation of
the Transactions or any other transactions contemplated hereby, (ii) any Loan or
Letter of Credit or the use of the proceeds therefrom (including any refusal by
the Issuing Bank to honor a demand for payment under a Letter of Credit if the
documents presented in connection with such demand do not strictly comply with
the terms of such Letter of Credit) or (iii) any actual or alleged presence or
release of Hazardous Materials on or from any property owned or operated by the
Borrower or any of its Subsidiaries, or any Environmental Liability related in
any way to the Borrower or any of its Subsidiaries; provided that the foregoing
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses are determined by a
court of competent jurisdiction by final judgment to have resulted from the
gross negligence, willful misconduct or bad faith of such Indemnitee. Upon
receipt of notice of any Third-Party Claim, the Indemnitee shall promptly notify
the Borrower thereof. The Borrower, in its sole discretion, upon written notice
of the Indemnitee(s), may elect to defend (or may at any time assume the defense
of) and may, with the consent of the Indemnitee(s) (such consent not to be
unreasonably withheld), settle or compromise any such Third-Party Claim, using
counsel appointed by Borrower, which counsel shall be reasonably satisfactory to
the Indemnitee if such settlement or compromise would result in the full release
of Indemnitee from any liability arising thereof, or with the consent of the
Indemnitee (not to be unreasonably withheld). No Indemnitee may compromise or
settle or consent to the entry of judgment or determination of liability with
respect to a Third-Party Claim for which it is seeking indemnification hereof,
without the consent of Borrower.

          (c) To the extent that the Borrower fails to pay any amount required
to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline
Lenders under paragraph (a) or (b) of this Section, (i) each Lender severally
agrees to pay to the Administrative Agent and (ii) each Revolving Lender
severally agrees to pay to the Issuing Bank or the Swingline Lenders, as the
case may be, respectively, such Lender's Applicable Percentage with respect to
the Facilities and such Revolving Lender's Applicable Percentage with respect to
the Revolving Credit Facility (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such respective unpaid
amounts; provided that the unreimbursed expense or indemnified loss, claim,
damage, liability or related expense, as the case may be, was incurred by or
asserted against the Administrative Agent, the Issuing Bank or any Swingline
Lender in its capacity as such.

          (d) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

          (e) All amounts due under this Section shall be payable promptly after
written demand therefor.

          SECTION 9.04. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i)
the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender (and any
such attempted assignment or transfer by the Borrower without such consent shall
be null and void) and (ii) no Lender may assign or otherwise transfer its rights
or obligations hereunder except in accordance with this Section. Nothing in this
Agreement, expressed or implied, shall be construed to confer upon any Person
(other than the parties hereto, their respective successors and assigns
permitted hereby (including any Affiliate of the Issuing Bank that issues any
Letter of Credit), Participants (to the extent provided in paragraph (c) of this
Section) and, to the extent expressly contemplated hereby, the Related Parties
of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal
or equitable right, remedy or claim under or by reason of this Agreement.

          (b) (i) Subject to the conditions set forth in paragraph (b)(ii)
below, any Lender may assign to one or more assignees all or a portion of its
rights and obligations under this Agreement (including all or a portion of its
Total Commitments and the Loans at the time owing to it) with the prior written
consent (such consent not to be unreasonably withheld) of:

                  (A) the Borrower, provided that no consent of the Borrower
     shall be required for an assignment to a Lender, an Affiliate of a Lender,
     an Approved Fund (as defined below) or, if an Event of Default under
     paragraph (a), (b), (h) or (i) of Article VII has occurred and is
     continuing, any other assignee; and

                  (B) the Administrative Agent, provided that no consent of the
     Administrative Agent shall be required for an assignment (i) with respect
     to any Term Loan, to an assignee that is a Lender, an Affiliate of a Lender
     or a Federal Reserve Bank,

                                      -77-

<PAGE>

     immediately prior to giving effect to such assignment or (ii) with respect
     to the Revolving Credit Facility, to an assignee that is a Lender under the
     Revolving Credit Facility.

          (ii)  Assignments shall be subject to the following additional
conditions:

                    (A) except in the case of an assignment to a Lender or an
     Affiliate of a Lender or an assignment of the entire remaining amount of
     the assigning Lender's Total Commitment, the amount of the Total Commitment
     of the assigning Lender subject to each such assignment (determined as of
     the date the Assignment and Assumption with respect to such assignment is
     delivered to the Administrative Agent) shall not be less than $1,000,000
     unless each of the Borrower and the Administrative Agent otherwise consent,
     provided that no such consent of the Borrower shall be required if an Event
     of Default under paragraph (a), (b), (h) or (i) of Article VII has occurred
     and is continuing;

                    (B) each partial assignment shall be made as an assignment
     of a proportionate part of all an assigning Lender's rights and obligations
     under this Agreement; provided that this Section 9.04(b)(ii)(B) shall not
     be construed to prohibit assignment of a proportionate part of all such
     assigning Lender's rights and obligations in respect of one Class of Loans
     (or commitments to make any such Loans);

                    (C) the parties to each assignment shall execute and deliver
     to the Administrative Agent an Assignment and Assumption, together with a
     processing and recordation fee of $3,500;/1/

                    (D) the assignee, if it is not an existing Lender, shall
     deliver to the Administrative Agent an Administrative Questionnaire; and

                    (E) in the case of an assignment to a CLO (as defined
     below), the assigning Lender shall retain the sole right to approve any
     amendment, modification or waiver of any provision of this Agreement,
     provided that the Assignment and Assumption between such Lender and such
     CLO may provide that such Lender will not, without the consent of such CLO,
     agree to any amendment, modification or waiver described in the first
     proviso to Section 9.02(b) that affects such CLO.

          For the purposes of this Section 9.04(b), the terms "Approved Fund"
and "CLO" have the following meanings:

                    "Approved Fund" means (a) a CLO and (b) with respect to any
     Lender that is a fund which invests in bank loans and similar extensions of
     credit, any other fund that invests in bank loans and similar extensions of
     credit and is managed by the same investment advisor as such Lender or by
     an Affiliate of such investment advisor.

                    "CLO" means any entity (whether a corporation, partnership,
     trust or otherwise) that is engaged in making, purchasing, holding or
     otherwise investing in bank

/1/ Any exceptions to be determined.

                                      -78-

<PAGE>

     loans and similar extensions of credit in the ordinary course of its
     business and is administered or managed by a Lender or an Affiliate of such
     Lender.

          (iii) Subject to acceptance and recording thereof pursuant to
     paragraph (b)(iv) of this Section 9.04, from and after the effective date
     specified in each Assignment and Assumption the assignee thereunder shall
     be a party hereto and, to the extent of the interest assigned by such
     Assignment and Assumption, have the rights and obligations of a Lender
     under this Agreement, and the assigning Lender thereunder shall, to the
     extent of the interest assigned by such Assignment and Assumption, be
     released from its obligations under this Agreement (and, in the case of an
     Assignment and Assumption covering all of the assigning Lender's rights and
     obligations under this Agreement, such Lender shall cease to be a party
     hereto but shall continue to be entitled to the benefits of Sections 2.14,
     2.15, 2.16 and 9.03). Any assignment or transfer by a Lender of rights or
     obligations under this Agreement that does not comply with this Section
     9.04 shall be treated for purposes of this Agreement as a sale by such
     Lender of a participation in such rights and obligations in accordance with
     paragraph (c) of this Section 9.04.

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

          (v)   Upon its receipt of a duly completed Assignment and Assumption
     executed by an assigning Lender and an assignee, the assignee's completed
     Administrative Questionnaire (unless the assignee shall already be a Lender
     hereunder), the processing and recordation fee referred to in paragraph
     (b)(ii)(C) of this Section 9.04 and any written consent to such assignment
     required by paragraph (b)(i) of this Section 9.04, the Administrative Agent
     shall accept such Assignment and Assumption and record the information
     contained therein in the Register. No assignment shall be effective for
     purposes of this Agreement unless it has been recorded in the Register as
     provided in this paragraph.

          (c) (i) Any Lender may, without the consent of the Borrower, the
Administrative Agent, the Issuing Bank or the Swingline Lenders, sell
participations to one or more banks or other entities (a "Participant") in all
or a portion of such Lender's rights and obligations under this Agreement
(including all or a portion of its Total Commitment and the Loans owing to it);
provided that (A) such Lender's obligations under this Agreement shall remain
unchanged, (B) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations arising from such participations
so sold by such Lender and (C) the Borrower, the Administrative Agent, the
Issuing Bank and the other Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender's rights and obligations under
this Agreement. Any agreement or instrument pursuant to which a Lender sells

                                      -79-

<PAGE>

such a participation shall provide that such Lender shall retain the sole right
to enforce this Agreement and to approve any amendment, modification or waiver
of any provision of this Agreement; provided that such agreement or instrument
may provide that such Lender will not, without the consent of the Participant,
agree to any amendment, modification or waiver described in the first proviso to
Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of
this Section 9.04, the Borrower agrees that each Participant shall be entitled
to the benefits of Sections 2.14, 2.15 and 2.16 to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to paragraph (b)
of this Section 9.04. To the extent permitted by law, each Participant also
shall be entitled to the benefits of Section 9.08 as though it were a Lender,
provided that such Participant agrees to be subject to Section 2.17(c) as though
it were a Lender.

        (ii) A Participant shall not be entitled to receive any greater
     payment under Sections 2.14, 2.15 or 2.16 than the applicable Lender would
     have been entitled to receive with respect to the participation sold to
     such Participant, unless the sale of the participation to such Participant
     is made with the Borrower's prior written consent. A Participant that would
     be a Foreign Lender if it were a Lender shall not be entitled to the
     benefits of Section 2.16 unless the Borrower is notified of the
     participation sold to such Participant and such Participant agrees, for the
     benefit of the Borrower, to comply with Section 2.16(e) and (f) as though
     it were a Lender.

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

          SECTION 9.05. Survival. All covenants, agreements, representations and
warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the
Administrative Agent, the Issuing Bank or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid or any
Letter of Credit is outstanding and so long as the Commitments have not expired
or terminated. The provisions of Sections 2.14, 2.15, 2.16 and 9.03 and Article
VIII shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof.

          SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative
Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings,
oral or written,

                                      -80-

<PAGE>

relating to the subject matter hereof. Except as provided in Section 4.01, this
Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received
counterparts hereof which, when taken together, bear the signatures of each of
the other parties hereto, and thereafter shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.
Delivery of an executed counterpart of a signature page of this Agreement by
telecopy shall be effective as delivery of a manually executed counterpart of
this Agreement.

               SECTION 9.07.  Severability. Any provision of this Agreement held
to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

               SECTION 9.08.  Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of the
Borrower against any of and all the obligations of the Borrower now or hereafter
existing under this Agreement held by such Lender, irrespective of whether or
not such Lender shall have made any demand under this Agreement and although
such obligations may be unmatured. The rights of each Lender under this Section
9.08 are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

               SECTION 9.09.  Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

               (b)  The Borrower hereby irrevocably and unconditionally submits,
for itself and its property, to the nonexclusive jurisdiction of the Supreme
Court of the State of New York sitting in New York County and of the United
States District Court of the Southern District of New York, and any appellate
court from any thereof, in any action or proceeding arising out of or relating
to this Agreement, or for recognition or enforcement of any judgment, and each
of the parties hereto hereby irrevocably and unconditionally agrees that all
claims in respect of any such action or proceeding may be heard and determined
in such New York State or, to the extent permitted by law, in such Federal
court. Each of the parties hereto agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that the Administrative Agent,
the Issuing Bank or any Lender may otherwise have to bring any action or
proceeding relating to this Agreement against the Borrower or its properties in
the courts of any jurisdiction.

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

                                      -81-

<PAGE>

               (d)  Each party to this Agreement irrevocably consents to service
of process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

               SECTION 9.10.  WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

               SECTION 9.11.  Headings. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not
part of this Agreement and shall not affect the construction of, or be taken
into consideration in interpreting, this Agreement.

               SECTION 9.12.  Confidentiality. (a) Subject as provided in
paragraph (b) below, each of the Administrative Agent, the Issuing Bank and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (i) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (ii) to the extent requested
by any regulatory authority, (iii) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (iv) to any other party
to this Agreement, (v) in connection with the exercise of any remedies hereunder
or any suit, action or proceeding relating to this Agreement or the enforcement
of rights hereunder, (vi) subject to an agreement containing provisions
substantially the same as those of this Section, to (x) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement or (y) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
the Borrower and its obligations, (vii) with the consent of the Borrower or
(viii) to the extent such Information (x) becomes publicly available other than
as a result of a breach of this Section 9.12 or (y) becomes available to the
Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis
from a source other than the Borrower or any of its Affiliates. For the purposes
of this paragraph, "Information" means all information received from the
Borrower or any of its Affiliates relating to the Borrower or its business in
connection with the facilities for the Loans in connection with the performance
by the Administrative Agent, Issuing Bank and the Lenders, other than any such
information that is available to the Administrative Agent, the Issuing Bank or
any Lender on a nonconfidential basis prior to disclosure by the Borrower or any
of its Affiliates; provided that, in the case of information received from the
Borrower after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this paragraph shall

                                      -82-

<PAGE>

be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.
Notwithstanding the foregoing, nothing in this paragraph shall be deemed to (1)
restrict or affect the rights or ability of the Administrative Agent, the
Issuing Bank or the Lenders to comply with all applicable disclosure laws,
regulations and principles in connection with the Spin-Off, the Notes Offering
or related transactions, (2) restrict the ability of the Administrative Agent,
the Issuing Bank or the Lenders to share information with underwriters
participating in the Spin-Off, the Notes Offering or related transactions, (3)
prevent the Administrative Agent, the Issuing Bank or the Lenders from retaining
documents or other information in connection with due diligence, including any
documents or other information disclosed to the Administrative Agent, the
Issuing Bank or the Lenders in connection with the transactions contemplated
hereby, (4) restrict or affect the rights or ability of the Administrative
Agent, the Issuing Bank or the Lenders to use any such documents or other
information in investigating or defending itself against allegations or claims
made or threatened by purchasers, regulatory authorities or others in connection
with the Spin-Off, the Notes Offering or related transactions, or (5) prevent
the Administrative Agent, the Issuing Bank or the Lenders from disclosing any
confidential information required to be disclosed by an applicable statute,
rule, regulation or other legal requirement in connection with or arising out of
the Spin-Off, the Notes Offering or related transactions.

               (b)  Notwithstanding the provisions of Section 9.12(a) or
anything to the contrary set forth herein, each party to this Agreement (and
each of their respective employees, representatives or other agents) may
disclose to any and all persons, without limitations of any kind, the tax
treatment and tax structure of the Transactions and all materials of any kind
(including opinions and other tax analyses) that are provided to any such party
relating to such party's tax treatment and tax structure. However, any
information relating to the tax treatment or tax structure shall remain subject
to the confidentiality provisions hereof (and the foregoing sentence shall not
apply) to the extent reasonably necessary to enable the parties hereto, their
respective Affiliates, and their and their respective Affiliates' directors and
employees to comply with applicable securities laws. For this purpose, "tax
structure" means any facts relevant to the federal income tax treatment of the
Transactions but does not include information relating to the identity of any of
the parties hereto or any of their respective Affiliates.

               SECTION 9.13.  Interest Rate Limitation. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.
