ARTICLE II

The Credits

SECTION 2.01. Commitments. Subject to the terms and conditions and relying upon the
representations and warranties herein set forth, each Lender agrees, severally and not jointly, (a)
to make Term Loans to the Borrowers (allocated among the Borrowers as specified in the Borrowing
Requests with respect thereto) on the Closing Date in an aggregate principal amount not to exceed
its Term Loan Commitment, (b) to make Revolving Loans to the Borrowers, at any time and from time
to time after the Closing Date, and until the earlier of the Revolving Credit Maturity Date and the
termination of the Revolving Credit Commitment of such Lender in accordance with the terms hereof,
in an aggregate principal amount at any time outstanding that will not result in such Lender’s
Revolving Credit Exposure exceeding such Lender’s Revolving Credit Commitment and (c) if such
Lender has an Incremental Term Loan Commitment, to make Incremental Term Loans to the applicable
Borrower, in an aggregate principal amount not to exceed its Incremental Term Loan Commitment on
the date or dates determined in accordance with Section 2.24. Within the limits set forth in
clause (b) of the preceding sentence and subject to the terms, conditions and limitations set forth
herein, the Borrowers may borrow, pay or prepay and reborrow Revolving Loans. Amounts paid or
prepaid in respect of Term Loans may not be reborrowed. Notwithstanding anything to the contrary
contained herein (and without affecting any other provision hereof), the funded portion of each
Term Loan to be made on the Closing Date (i.e., the amount advanced in cash to the Borrowers on the
Closing Date) shall be equal to 99.5% of the principal amount of such Loan (it being agreed that
the Borrowers shall be obligated to pay the entire principal amount of each such Loan as provided
in Section 2.11).

SECTION 2.02. Loans. (a) Each Loan (other than Swingline Loans) shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with their applicable
Commitments; provided, however, that the failure of any Lender to make any Loan shall not in itself
relieve any other Lender of its obligation to lend hereunder (it being understood, however, that no
Lender shall be responsible for the failure of any other Lender to make any Loan required to be
made by such other Lender). Except for Loans deemed made pursuant to Section 2.02(f), the Loans
comprising any Borrowing shall be in an aggregate principal amount that is (i) an integral multiple
of $1,000,000 and not less than $5,000,000 or (ii) equal to the remaining available balance of the
applicable Commitments.

(b) Subject to Sections 2.08 and 2.15, each Borrowing shall be comprised entirely of ABR Loans
or Eurodollar Loans as the applicable Borrower may request pursuant to Section 2.03. Each Lender
may at its option make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate
of such Lender to make such Loan; provided that any exercise of such option shall not affect the
obligation of any Borrower to repay such Loan in accordance with the terms of this Agreement.
Borrowings of more than one Type may be outstanding at the same time; provided, however, that the
Borrowers shall not be entitled to request any Borrowing that, if made, would result in more than
five Eurodollar Borrowings outstanding hereunder at any time. For purposes of the foregoing,
Borrowings having different Interest Periods, regardless of whether they commence on the same date,
shall be considered separate Borrowings.

(c) Except with respect to Loans made pursuant to Section 2.02(f), each Lender shall make each
Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately
available funds to such account as the Administrative Agent may designate not later than 1:00 p.m.,
New York City time, and the Administrative Agent shall promptly credit the amounts so received to
an account designated by the applicable Borrower in the applicable Borrowing Request or, if a
Borrowing shall not occur on such date because any condition precedent herein specified shall not
have been met, return the amounts so received to the respective Lenders. The Rollover Lenders
shall be deemed to have funded a portion of the Term Loans to be made by them hereunder equal to
the Rollover Amount through the conversion of the Discount Notes as provided in the Rollover
Agreement and Section 4.02(i), and shall not be required to fund such portion of their Term Loans
pursuant to the immediately preceding sentence (it being agreed that such deemed funding shall not
affect the applicable Borrowers’ obligation to pay the entire principal amount of the Term Loans of
the Rollover Lenders as provided in Section 2.11).

(d) Unless the Administrative Agent shall have received notice from a Lender prior to the date
of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s
portion of such Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such Borrowing in accordance with
paragraph (c) of this Section and the Administrative Agent may, in its sole discretion and in
reliance upon such assumption, make available to the applicable Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds available, then, to the
extent that such Lender shall not have made such portion available to the Administrative Agent,
such Lender and the applicable Borrower severally agree to repay to the Administrative Agent
forthwith on demand such corresponding amount together with interest thereon, for each day from and
including the date such amount is made available to such Borrower to but excluding the date such
amount is repaid to the Administrative Agent at (i) in the case of such Borrower, a rate per annum
equal to the interest rate applicable at the time to the Loans comprising such Borrowing and (ii)
in the case of such Lender, (A) for the first three days following the date such amount is made
available to such Borrower, a rate determined by the Administrative Agent to represent its cost of
overnight or short-term funds (which determination shall be conclusive absent manifest error) and
(B) thereafter, at the Alternate Base Rate. If such Lender shall repay to the Administrative Agent
such corresponding amount, such amount shall constitute such Lender’s Loan as part of such
Borrowing for purposes of this Agreement.

(e) Notwithstanding any other provision of this Agreement, the Borrowers shall not be entitled
to request any Revolving Credit Borrowing if the Interest Period requested with respect thereto
would end after the Revolving Credit Maturity Date.

(f) If the Issuing Bank shall not have received from any Borrower the payment required to be
made by Section 2.23(e) within the time specified in such Section, the Issuing Bank will promptly
notify the Administrative Agent of the L/C Disbursement and the Administrative Agent will promptly
notify each Revolving Credit Lender of such L/C Disbursement and its Pro Rata Percentage thereof.
Each Revolving Credit Lender shall pay by wire transfer of immediately available funds to the
Administrative Agent not later than 2:00 p.m., New York City time, on such date (or, if such
Revolving Credit Lender shall have received such notice later than 12:00 noon, New York City time,
on any day, not later than 10:00 a.m., New York City time, on the immediately following Business
Day), an amount equal to such Lender’s Pro Rata Percentage of such L/C Disbursement (it being
understood that such amount shall be deemed to constitute an ABR Revolving Loan of such Lender and
such payment shall be deemed to have reduced the L/C Exposure), and the Administrative Agent will
promptly pay to the Issuing Bank amounts so received by it from the Revolving Credit Lenders. The
Administrative Agent will promptly pay to the Issuing Bank any amounts received by it from the
applicable Borrower pursuant to Section 2.23(e) prior to the time that any Revolving Credit Lender
makes any payment pursuant to this paragraph; any such amounts received by the Administrative Agent
thereafter will be promptly remitted by the Administrative Agent to the Revolving Credit Lenders
that shall have made such payments and to the Issuing Bank, as their interests may appear. If any
Revolving Credit Lender shall not have made its Pro Rata Percentage of such L/C Disbursement
available to the Administrative Agent as provided above, such Lender and the applicable Borrower
severally agree to pay interest on such amount, for each day from and including the date such
amount is required to be paid in accordance with this paragraph to but excluding the date such
amount is paid, to the Administrative Agent for the account of the Issuing Bank at (i) in the case
of such Borrower, a rate per annum equal to the interest rate applicable at the time to Revolving
Loans pursuant to Section 2.06(a), and (ii) in the case of such Lender, a rate per annum equal to,
for the first such day, the Federal Funds Effective Rate and, for each day thereafter, the
Alternate Base Rate.

SECTION 2.03. Borrowing Procedure. In order to request a Borrowing (other than a Swingline
Loan or a deemed Borrowing pursuant to Section 2.02(f), as to which this Section shall not apply),
a Borrower shall hand deliver or fax to the Administrative Agent a duly completed Borrowing Request
(a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three
Business Days before a proposed Borrowing, and (b) in the case of an ABR Borrowing, not later than
12:00 noon, New York City time, one Business Day before a proposed Borrowing. Each Borrowing
Request shall be irrevocable, shall be signed by or on behalf of the applicable Borrower and shall
specify the following information: (i) whether the Borrowing then being requested is to be a Term
Borrowing, an Other Term Borrowing or a Revolving Credit Borrowing, and whether such Borrowing is
to be a Eurodollar Borrowing or an ABR Borrowing; (ii) the date of such Borrowing (which shall be a
Business Day); (iii) the number and location of the account to which funds are to be disbursed;
(iv) the amount of such Borrowing; and (v) if such Borrowing is to be a Eurodollar Borrowing, the
Interest Period with respect thereto; provided, however, that, notwithstanding any contrary
specification in any Borrowing Request, each requested Borrowing shall comply with the requirements
set forth in Section 2.02. If no election as to the Type of Borrowing is specified in any such
notice, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period with respect
to any Eurodollar Borrowing is specified in any such notice, then the applicable Borrower shall be
deemed to have selected an Interest Period of one month’s duration. The Administrative Agent shall
promptly advise the applicable Lenders of any notice given pursuant to this Section, and of each
Lender’s portion of the requested Borrowing.

SECTION 2.04. Evidence of Debt; Repayment of Loans. (a) Each Borrower hereby unconditionally
promises to pay to the Administrative Agent for the account of each Lender (i) the principal amount
of each Term Loan of such Lender as provided in Section 2.11 and (ii) the then unpaid principal
amount of each Revolving Loan of such Lender on the Revolving Credit Maturity Date. Each Borrower
hereby promises to pay to the Swingline Lender the then unpaid principal amount of each Swingline
Loan on the Revolving Credit Maturity Date.

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

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

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

(e) Any Lender may request that Loans made by it hereunder be evidenced by a promissory note.
In such event, the applicable Borrower shall execute and deliver to such Lender a promissory note
payable to such Lender and its registered assigns and in a form and substance reasonably acceptable
to the Administrative Agent and the Borrowers. Notwithstanding any other provision of this
Agreement, in the event any Lender shall request and receive such a promissory note, the interests
represented by such note shall at all times (including after any assignment of all or part of such
interests pursuant to Section 9.04) be represented by one or more promissory notes payable to the
payee named therein or its registered assigns.

SECTION 2.05. Fees. (a) The Borrowers agree to pay to each Lender, through the
Administrative Agent, on the last Business Day of March, June, September and December in each year
and on the date on which the Revolving Credit Commitment of such Lender shall expire or be

the daily unused amount of the Revolving Credit Commitment of such Lender during the preceding
quarter (or shorter period commencing with the date hereof or ending with the Revolving Credit
Maturity Date or the date on which the Revolving Credit Commitment of such Lender shall be
terminated). All Commitment Fees shall be computed on the basis of the actual number of days
elapsed in a year of 360 days. For purposes of calculating Commitment Fees only, outstanding
Swingline Loans shall not be deemed to constitute utilization of the Revolving Credit Commitments.

(b) The Borrowers agree to pay to the Administrative Agent, for its own account, the
administrative fees set forth in the Fee Letter at the times and in the amounts specified therein
(the “Administrative Agent Fees”).

(c) The Borrowers agree to pay (i) to each Revolving Credit Lender, through the Administrative
Agent, on the last Business Day of March, June, September and December of each year and on the date
on which the Revolving Credit Commitment of such Lender shall be terminated as provided herein, a
fee (an “L/C Participation Fee”) calculated on such Lender’s Pro Rata Percentage of the daily
aggregate L/C Exposure (excluding the portion thereof attributable to unreimbursed L/C
Disbursements) during the preceding quarter (or shorter period commencing with the date hereof or
ending with the Revolving Credit Maturity Date or the date on which all Letters of Credit have been
canceled or have expired and the Revolving Credit Commitments of all Lenders shall have been
terminated) at a rate per annum equal to the Applicable Percentage from time to time used to
determine the interest rate on Revolving Credit Borrowings comprised of Eurodollar Loans pursuant
to Section 2.06, and (ii) to the Issuing Bank, (x) on the last Business Day of March, June,
September and December of each year and on the date on which all the Letters of Credit issued by it

face amount of such Letters of Credit outstanding during the preceding quarter (or shorter period
commencing on the date hereof or ending on the date on which all Letters of Credit have been
canceled or have expired) and (y) the standard issuance and drawing fees specified from time to
time by the Issuing Bank (the “Issuing Bank Fees”). All L/C Participation Fees and Issuing Bank
Fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days.

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

SECTION 2.06. Interest on Loans. (a) Subject to the provisions of Section 2.07, the Loans
comprising each ABR Borrowing, including each Swingline Loan, shall bear interest (computed on the
basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, when
the Alternate Base Rate is determined by reference to the Prime Rate and over a year of 360 days at
all other times and calculated from and including the date of such Borrowing to but excluding the
date of repayment thereof) at a rate per annum equal to the Alternate Base Rate plus the Applicable
Percentage in effect from time to time.

(b) Subject to the provisions of Section 2.07, the Loans comprising each Eurodollar Borrowing
shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for
such Borrowing plus the Applicable Percentage in effect from time to time.

(c) Interest on each Loan shall be payable on the Interest Payment Dates applicable to such
Loan except as otherwise provided in this Agreement. The applicable Alternate Base Rate or
Adjusted LIBO Rate for each Interest Period or day within an Interest Period, as the case may be,
shall be determined by the Administrative Agent, and such determination shall be conclusive absent
manifest error.

SECTION 2.07. Default Interest. If any Borrower shall default in the payment of any principal
of or interest on any Loan or any other amount due hereunder, by acceleration or otherwise, or
under any other Loan Document, then, until such defaulted amount shall have been paid in full, to
the extent permitted by law, all amounts outstanding under this Agreement and the other Loan
Documents shall bear interest (after as well as before judgment), payable on demand, (a) in the
case of principal, at the rate otherwise applicable to such Loan pursuant to Section 2.06 plus 2%
per annum and (b) in all other cases, at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as the case may be, when determined by
reference to the Prime Rate and over a year of 360 days at all other times) equal to the rate that
would be applicable to an ABR Loan plus 2% per annum.

SECTION 2.08. Alternate Rate of Interest. In the event, and on each occasion, that on the day
two Business Days prior to the commencement of any Interest Period for a Eurodollar Borrowing the
Administrative Agent shall have determined that dollar deposits in the principal amounts of the
Loans comprising such Borrowing are not generally available in the London interbank market, or that
the rates at which such dollar deposits are being offered will not adequately and fairly reflect
the cost to any Lender of making or maintaining its Eurodollar Loan during such Interest Period, or
that reasonable means do not exist for ascertaining the Adjusted LIBO Rate, the Administrative
Agent shall, as soon as practicable thereafter, give written or fax notice of such determination to
the Borrowers and the Lenders. In the event of any such determination, until the Administrative
Agent shall have advised the Borrowers and the Lenders that the circumstances giving rise to such
notice no longer exist, any request by any Borrower for a Eurodollar Borrowing pursuant to Section
2.03 or 2.10 shall be deemed to be a request for an ABR Borrowing. Each determination by the
Administrative Agent under this Section shall be conclusive absent manifest error.

SECTION 2.09. Termination and Reduction of Commitments. (a) The Term Loan Commitments shall
automatically terminate upon the making of the Term Loans on the Closing Date. Unless earlier
terminated pursuant to the terms hereof, the Revolving Credit Commitments and the Swingline
Commitment shall automatically terminate on the Revolving Credit Maturity Date. The L/C Commitment
shall, with respect to issuance of Letters of Credit, automatically terminate on the earlier to
occur of (i) the date 30 days prior to the Revolving Credit Maturity Date and (ii) the termination
of the Revolving Credit Commitments. Notwithstanding the foregoing, all Commitments shall
automatically terminate at 5:00 p.m., New York City time, on the date hereof, if the initial Credit
Event shall not have occurred by such time (other than as a result of a breach of this Credit
Agreement by any Lender).

(b) Upon at least three Business Days’ prior irrevocable written or fax notice to the
Administrative Agent, Parent may at any time in whole permanently terminate, or from time to time
in part permanently reduce, the Incremental Term Loan Commitments or the Revolving Credit
Commitments; provided, however, that (i) each partial reduction of the Incremental Term Loan
Commitments or the Revolving Credit Commitments shall be in an integral multiple of $1,000,000 and
in a minimum amount of $5,000,000 and (ii) the Total Revolving Credit Commitment shall not be
reduced to an amount that is less than the Aggregate Revolving Credit Exposure at the time.

(c) Each reduction in the Incremental Term Loan Commitments or the Revolving Credit
Commitments hereunder shall be made ratably among the Lenders in accordance with their respective
applicable Commitments. The Borrowers shall pay to the Administrative Agent for the account of the
applicable Lenders, on the date of each termination or reduction, the accrued but unpaid Commitment
Fees on the amount of the Revolving Credit Commitments so terminated or reduced accrued to but
excluding the date of such termination or reduction.

SECTION 2.10. Conversion and Continuation of Borrowings. The applicable Borrower shall have
the right at any time upon prior irrevocable notice to the Administrative Agent (a) not later than
12:00 noon, New York City time, one Business Day prior to conversion, to convert any Eurodollar
Borrowing into an ABR Borrowing, (b) not later than 12:00 noon, New York City time, three Business
Days prior to conversion or continuation, to convert any ABR Borrowing into a Eurodollar Borrowing
or to continue any Eurodollar Borrowing as a Eurodollar Borrowing for an additional Interest
Period, and (c) not later than 12:00 noon, New York City time, three Business Days prior to
conversion, to convert the Interest Period with respect to any Eurodollar Borrowing to another
permissible Interest Period, subject in each case to the following:

(i) each conversion or continuation shall be made pro rata among the Lenders in
accordance with the respective principal amounts of the Loans comprising the converted or
continued Borrowing;

(ii) if less than all the outstanding principal amount of any Borrowing shall be
converted or continued, then each resulting Borrowing shall satisfy the limitations
specified in Sections 2.02(a) and (b) regarding the principal amount and maximum number of
Borrowings of the relevant Type;

(iii) each conversion shall be effected by each Lender and the Administrative Agent by
recording for the account of such Lender the new Loan of such Lender resulting from such
conversion and reducing the Loan (or portion thereof) of such Lender being converted by an
equivalent principal amount; accrued interest on any Eurodollar Loan (or portion thereof)
being converted shall be paid by the applicable Borrower at the time of conversion;

(iv) if any Eurodollar Borrowing is converted at a time other than the end of the
Interest Period applicable thereto, the applicable Borrower shall pay, upon demand, any
amounts due to the Lenders pursuant to Section 2.16;

(v) any portion of a Borrowing maturing or required to be repaid in less than one
month may not be converted into or continued as a Eurodollar Borrowing;

(vi) any portion of a Eurodollar Borrowing that cannot be converted into or continued
as a Eurodollar Borrowing by reason of the immediately preceding clause shall be
automatically converted at the end of the Interest Period in effect for such Borrowing into
an ABR Borrowing;

(vii) no Interest Period may be selected for any Eurodollar Term Borrowing that would
end later than a Repayment Date occurring on or after the first day of such Interest Period
if, after giving effect to such selection, the aggregate outstanding amount of (A) the
Eurodollar Term Borrowings with Interest Periods ending on or prior to such Repayment Date
and (B) the ABR Term Borrowings would not be at least equal to the principal amount of Term
Borrowings to be paid on such Repayment Date; and

(viii) upon notice to the Borrowers from the Administrative Agent given at the request
of the Required Lenders, after the occurrence and during the continuance of an Event of
Default, no outstanding Loan may be converted into, or continued as, a Eurodollar Loan.

Each notice pursuant to this Section shall be irrevocable, shall be substantially in the form
of Exhibit E or such other form as shall be acceptable to the Administrative Agent and shall refer
to this Agreement and specify (i) the identity and amount of the Borrowing that the applicable
Borrower requests be converted or continued, (ii) whether such Borrowing is to be converted to or
continued as a Eurodollar Borrowing or an ABR Borrowing, (iii) if such notice requests a
conversion, the date of such conversion (which shall be a Business Day) and (iv) if such Borrowing
is to be converted to or continued as a Eurodollar Borrowing, the Interest Period with respect
thereto. If no Interest Period is specified in any such notice with respect to any conversion to
or continuation as a Eurodollar Borrowing, the applicable Borrower shall be deemed to have selected
an Interest Period of one month’s duration. The Administrative Agent shall advise the Lenders of
any notice given pursuant to this Section and of each Lender’s portion of any converted or
continued Borrowing. If any Borrower shall not have given notice in accordance with this Section
to continue any Borrowing into a subsequent Interest Period (and shall not otherwise have given
notice in accordance with this Section to convert such Borrowing), such Borrowing shall, at the end
of the Interest Period applicable thereto (unless repaid pursuant to the terms hereof),
automatically be continued into an ABR Borrowing.

SECTION 2.11. Repayment of Term Borrowings. (a) The Borrowers shall pay to the
Administrative Agent, for the accounts of the applicable Lenders, the aggregate principal amount of
the Term Borrowings (other than Term Borrowings comprised of Other Term Loans) in consecutive
installments payable on the last Business Day of March, June, September and December of each year,
commencing, in the case of Term Borrowings made on the Closing Date, on the last Business Day in
September 2004 and ending on the Term Loan Maturity Date (each such date being called a “Repayment
Date”). Each installment payable in respect of (i) Term Loans made on the Closing Date shall be in
an amount equal to 0.25% of the initial aggregate principal amount of such Term Loans and (ii)
Incremental Term Loans of any Class (other than Other Term Loans) shall be in an amount equal to
0.25% of the initial aggregate principal amount of the Incremental Term Loans of such Class (in
each case as adjusted from time to time pursuant to Sections 2.12, 2.13(e) and 2.24(d)), with the
balance of all Term Loans (other than Other Term Loans) being due and payable on the Term Loan
Maturity Date.

(b) The Borrowers shall pay to the Administrative Agent, for the accounts of the applicable
Lenders, on each Incremental Term Loan Repayment Date applicable thereto, a principal amount of the
Other Term Loans of each Class (as adjusted from time to time pursuant to Sections 2.12, 2.13(e)
and 2.24(d)) equal to the amount set forth for such date in the applicable Incremental Term Loan
Assumption Agreement. To the extent not previously paid, all Other Term Loans shall be due and
payable on the Incremental Term Loan Maturity Date therefor.

(c) All repayments pursuant to this Section shall be subject to Section 2.16, but otherwise
shall be without premium or penalty, and shall be accompanied by accrued and unpaid interest on the
principal amount to be repaid to but excluding the date of payment.

SECTION 2.12. Optional Prepayments. (a) The Borrowers shall have the right at any time and
from time to time to prepay any Borrowing, in whole or in part, upon at least three Business Days’
prior written or fax notice (or telephone notice promptly confirmed by written or fax notice) in
the case of Eurodollar Loans, or written or fax notice (or telephone notice promptly confirmed by
written or fax notice) at least one Business Day prior to the date of prepayment in the case of ABR
Loans, to the Administrative Agent before 12:00 noon, New York City time; provided, however, that
each partial prepayment shall be in an amount that is an integral multiple of $1,000,000 and not
less than $5,000,000.

(b) Optional prepayments of Term Loans shall be allocated pro rata among the then outstanding
Term Loans of each Class and shall be applied, as to each such Class, first, in direct order to the
scheduled installments of principal due in respect of the Term Loans of such Class under Section
2.11(a) or (b), as applicable, on the two Repayment Dates for Term Loans of such Class next
following the date of such prepayment unless and until such installments have been eliminated as a
result of prepayments under this Section and Section 2.13, and second, ratably to the remaining
scheduled installments of principal due in respect of the Term Loans of such Class under Section
2.11(a) or (b), as applicable.

(c) Each notice of prepayment shall specify the prepayment date and the principal amount of
each Borrowing (or portion thereof) to be prepaid, shall be irrevocable (provided that the
occurrence of such prepayment may be conditioned upon the completion of replacement financing),
shall commit the applicable Borrower to prepay such Borrowing by the amount stated therein on the
date stated therein and shall be substantially in the form of Exhibit F or such other form as shall
be acceptable to the Administrative Agent. All prepayments under this Section shall be subject to
Section 2.16, but otherwise shall be without premium or penalty, and shall be accompanied by
accrued and unpaid interest on the principal amount to be prepaid to but excluding the date of
payment.

SECTION 2.13. Mandatory Prepayments. (a) In the event of the termination of all the
Revolving Credit Commitments, the Borrowers shall, on the date of such termination, repay or prepay
all outstanding Revolving Credit Borrowings and all outstanding Swingline Loans and replace or
cause to be terminated (or make other arrangements satisfactory to the Administrative Agent and the
Issuing Bank with respect to) all outstanding Letters of Credit. If, after giving effect to any
partial reduction of the Revolving Credit Commitments, the Aggregate Revolving Credit Exposure
would exceed the Total Revolving Credit Commitment, then the Borrowers shall, on the date of such
reduction, repay or prepay Revolving Credit Borrowings or Swingline Loans (or a combination
thereof), and, after the Revolving Credit Borrowings and Swingline Loans shall have been repaid or
prepaid in full, replace or cause to be terminated (or make other arrangements satisfactory to the
Administrative Agent and the Issuing Bank with respect to) Letters of Credit, in an amount
sufficient to eliminate such excess.

(b) Not later than the third Business Day following any receipt of Net Cash Proceeds in
respect of any Asset Sale, the Borrowers shall apply 100% of such Net Cash Proceeds to prepay
outstanding Term Loans in accordance with paragraph (e) of this Section.

(c) In the event and on each occasion that an Equity Issuance occurs, the Borrowers shall,
substantially simultaneously with (and in any event not later than the third Business Day next
following) the occurrence of such Equity Issuance, apply 50% of the Net Cash Proceeds therefrom to
prepay outstanding Term Loans in accordance with paragraph (e) of this Section; provided, however,
that no prepayment pursuant to this paragraph shall be required to be made with respect to (i) the
IPO, (ii) the underwritten primary public offering of the Equity Interests of Parent pursuant to an
effective registration statement filed with the Securities and Exchange Commission in accordance
with the Securities Act of 1933, as amended, next following the IPO or (iii) any other Equity
Issuance if, after giving pro forma effect to such issuance and the application of the proceeds
thereof (disregarding any such application pursuant to this paragraph), the Leverage Ratio on the
date of such issuance shall be not more than 3.25 to 1.00.

(d) In the event that Parent or any Subsidiary shall receive Net Cash Proceeds from the
issuance or other disposition of Indebtedness for money borrowed of Parent or any Subsidiary (other
than any cash proceeds from the issuance of Indebtedness for money borrowed permitted pursuant to
Section 6.01), the Borrowers shall, substantially simultaneously with (and in any event not later
than the third Business Day next following) the receipt of such Net Cash Proceeds by such Loan
Party or such subsidiary, apply an amount equal to 100% of such Net Cash Proceeds to prepay
outstanding Term Loans in accordance with paragraph (e) of this Section.

(e) Mandatory prepayments of Term Loans shall be allocated pro rata among the then outstanding
Term Loans of each Class and shall be applied, as to each such Class, first, in direct order to the
scheduled installments of principal due in respect of the Term Loans of such Class under Section
2.11(a) or (b), as applicable, on the two Repayment Dates for Term Loans of such Class next
following the date of such prepayment unless and until such installments have been eliminated as a
result of prepayments under this Section and Section 2.12, and second, ratably to the remaining
scheduled installments of principal due in respect of the Term Loans of such Class under Section
2.11(a) or (b), as applicable. Notwithstanding the foregoing, any Lender may elect, by notice to
the Administrative Agent in writing or by fax no later than 3:00 p.m., New York City time, at least
two Business Days prior to any prepayment of Term Loans required to be made by the Borrowers for
the account of such Lender pursuant to this Section, to decline all (but not a portion) of such
prepayment, in which case the amounts so declined will be retained by the Borrowers.

(f) The Borrowers shall deliver to the Administrative Agent, at the time of each prepayment
required under this Section, (i) a certificate signed by a Financial Officer of Parent setting
forth in reasonable detail the calculation of the amount of such prepayment and (ii) to the extent
practicable, at least three days prior written notice of such prepayment. Each notice of
prepayment shall specify the prepayment date and the principal amount of each Loan (or portion
thereof) to be prepaid and shall be substantially in the form of Exhibit F or such other form as
shall be acceptable to the Administrative Agent. All prepayments of Borrowings under this Section
shall be subject to Section 2.16, but otherwise shall be without premium or penalty, and shall be
accompanied by accrued and unpaid interest on the principal amount to be prepaid to but excluding
the date of payment.

SECTION 2.14. Reserve Requirements; Change in Circumstances.

(a) Notwithstanding any other provision of this Agreement, if any Change in Law shall impose,
modify or deem applicable any reserve, special deposit or similar requirement against assets of,
deposits with or for the account of or credit extended by any Lender or the Issuing Bank (except
any such reserve requirement which is reflected in the Adjusted LIBO Rate) or shall impose on such
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 or the Issuing
Bank of making or maintaining any Eurodollar Loan or increase the cost to any Lender of issuing or
maintaining any Letter of Credit or purchasing or maintaining a participation therein 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) by an amount deemed by such Lender or the Issuing Bank to be
material, then the Borrowers will pay to such Lender or the Issuing Bank, as the case may be, upon
demand 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 shall have determined that any Change in Law regarding
capital adequacy 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 or participations in Letters
of Credit purchased by such Lender pursuant hereto or the Letters of Credit issued by the Issuing
Bank pursuant hereto 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) by an amount deemed by such Lender
or the Issuing Bank to be material, then from time to time the Borrowers shall 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 or amounts
necessary to compensate such Lender or the Issuing Bank or its holding company, as applicable, as
specified in paragraph (a) or (b) of this Section shall be delivered to the Borrowers and shall be
conclusive absent manifest error. The Borrowers shall pay such Lender or the Issuing Bank the
amount shown as due on any such certificate delivered by it within 10 days after its receipt of the
same.

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation for
any increased costs or reduction in amounts received or receivable or reduction in return on
capital shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such
compensation; provided that the Borrowers shall not be under any obligation to compensate any
Lender or the Issuing Bank under paragraph (a) or (b) of this Section with respect to increased
costs or reductions with respect to any period prior to the date that is 120 days prior to such
request if such Lender or the Issuing Bank knew or could reasonably have been expected to know of
the circumstances giving rise to such increased costs or reductions and of the fact that such
circumstances would result in a claim for increased compensation by reason of such increased costs
or reductions; provided further that the foregoing limitation shall not apply to any increased
costs or reductions arising out of the retroactive application of any Change in Law within such
120-day period. The protection of this Section shall be available to each Lender and the Issuing
Bank regardless of any possible contention of the invalidity or inapplicability of the Change in
Law that shall have occurred or been imposed.

SECTION 2.15. Change in Legality. (a) Notwithstanding any other provision of this Agreement,
if any Change in Law shall make it unlawful for any Lender to make or maintain any Eurodollar Loan
or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan,
then, by written notice to the Borrowers and to the Administrative Agent:

(i) such Lender may declare that Eurodollar Loans will not thereafter (for the
duration of such unlawfulness) be made by such Lender hereunder (or be continued for
additional Interest Periods and ABR Loans will not thereafter (for such duration) be
converted into Eurodollar Loans), whereupon any request for a Eurodollar Borrowing (or to
convert an ABR Borrowing to a Eurodollar Borrowing or to continue a Eurodollar Borrowing
for an additional Interest Period) shall, as to such Lender only, be deemed a request for
an ABR Loan (or a request to continue an ABR Loan as such for an additional Interest Period
or to convert a Eurodollar Loan into an ABR Loan, as the case may be), unless such
declaration shall be subsequently withdrawn; and

(ii) such Lender may require that all outstanding Eurodollar Loans made by it be
converted to ABR Loans, in which event all such Eurodollar Loans shall be automatically
converted to ABR Loans as of the effective date of such notice as provided in paragraph (b)
of this Section.

In the event any Lender shall exercise its rights under clause (i) or (ii) above, all payments and
prepayments of principal that would otherwise have been applied to repay the Eurodollar Loans that
would have been made by such Lender or the converted Eurodollar Loans of such Lender shall instead
be applied to repay the ABR Loans made by such Lender in lieu of, or resulting from the conversion
of, such Eurodollar Loans.

(b) For purposes of this Section, a notice to the Borrowers by any Lender shall be effective
as to each Eurodollar Loan made by such Lender, if lawful, on the last day of the Interest Period
then applicable to such Eurodollar Loan; in all other cases such notice shall be effective on the
date of receipt by the Borrowers.

SECTION 2.16. Indemnity. The Borrowers shall indemnify each Lender against any loss or
expense that such Lender may sustain or incur as a consequence of (a) any event, other than a
default by such Lender in the performance of its obligations hereunder, which results in (i) such
Lender receiving or being deemed to receive any amount on account of the principal of any
Eurodollar Loan prior to the end of the Interest Period in effect therefor, (ii) the conversion of
any Eurodollar Loan to an ABR Loan, or the conversion of the Interest Period with respect to any
Eurodollar Loan, in each case other than on the last day of the Interest Period in effect therefor,
or (iii) any Eurodollar Loan to be made by such Lender (including any Eurodollar Loan to be made
pursuant to a conversion or continuation under Section 2.10) not being made after notice of such
Loan shall have been given by any Borrower hereunder (any of the events referred to in this clause
(a) being called a “Breakage Event”) or (b) any default in the making of any payment or prepayment
required to be made hereunder. In the case of any Breakage Event, such loss shall include an
amount equal to the excess, as reasonably determined by such Lender, of (i) its cost of obtaining
funds for the Eurodollar Loan that is the subject of such Breakage Event for the period from the
date of such Breakage Event to the last day of the Interest Period in effect (or that would have
been in effect) for such Loan over (ii) the amount of interest likely to be realized by such Lender
in redeploying the funds released or not utilized by reason of such Breakage Event for such period.
A certificate of any Lender setting forth any amount or amounts which such Lender is entitled to
receive pursuant to this Section shall be delivered to the Borrowers and shall be conclusive absent
manifest error.

SECTION 2.17. Pro Rata Treatment. Except as provided in Section 2.13(e) with respect to
mandatory prepayments and in this Section with respect to Swingline Loans, and as required under
Section 2.15, each Borrowing, each payment or prepayment of principal of any Borrowing, each
payment of interest on the Loans, each payment of the Commitment Fees, each reduction of the Term
Loan Commitments or the Revolving Credit Commitments and each conversion of any Borrowing to or
continuation of any Borrowing as a Borrowing of any Type shall be allocated pro rata among the
Lenders in accordance with their respective applicable Commitments (or, if such Commitments shall
have expired or been terminated, in accordance with the respective principal amounts of their
outstanding Loans). For purposes of determining the available Revolving Credit Commitments of the
Lenders at any time, each outstanding Swingline Loan shall be deemed to have utilized the Revolving
Credit Commitments of the Lenders (including those Lenders which shall not have made Swingline
Loans) pro rata in accordance with such respective Revolving Credit Commitments. Each Lender
agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the
Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing to
the next higher or lower whole dollar amount.

SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall, through the exercise
of a right of banker’s lien, setoff or counterclaim against any Borrower or any other Loan Party,
or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other
security or interest arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means,
obtain payment (voluntary or involuntary) in respect of any Loan or Loans or L/C Disbursement as a
result of which the unpaid principal portion of its Loans and participations in L/C Disbursements
shall be proportionately less than the unpaid principal portion of the Loans and participations in
L/C Disbursements of any other Lender, it shall be deemed simultaneously to have purchased from
such other Lender at face value, and shall promptly pay to such other Lender the purchase price
for, a participation in the Loans and L/C Exposure of such other Lender, so that the aggregate
unpaid principal amount of the Loans and L/C Exposure and participations in Loans and L/C Exposure
held by each Lender shall be in the same proportion to the aggregate unpaid principal amount of all
Loans and L/C Exposure then outstanding as the principal amount of its Loans and L/C Exposure prior
to such exercise of banker’s lien, setoff or counterclaim or other event was to the principal
amount of all Loans and L/C Exposure outstanding prior to such exercise of banker’s lien, setoff or
counterclaim or other event; provided, however, that if any such purchase or purchases or
adjustments shall be made pursuant to this Section and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent
of such recovery and the purchase price or prices or adjustment restored without interest. The
Borrowers and Parent expressly consent to the foregoing arrangements and agree that any Lender
holding a participation in a Loan or L/C Disbursement deemed to have been so purchased may exercise
any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys
owing by any Borrower or any other Loan Party to such Lender by reason thereof as fully as if such
Lender had made a Loan directly to a Borrower in the amount of such participation.

SECTION 2.19. Payments. (a) The Borrowers shall make each payment (including principal of or
interest on any Borrowing or any L/C Disbursement or any Fees or other amounts) hereunder and under
any other Loan Document not later than 12:00 noon, New York City time, on the date when due in
immediately available dollars, without setoff, defense or counterclaim. Each such payment (other
than (i) Issuing Bank Fees, which shall be paid directly to the Issuing Bank, and (ii) principal of
and interest on Swingline Loans, which shall be paid directly to the Swingline Lender except as
otherwise provided in Section 2.21(e)) shall be made to the Administrative Agent at its offices at
201 South College Street, CP-8, Charlotte, NC 28288-0608.

(b) Except as otherwise expressly provided herein, whenever any payment (including principal
of or interest on any Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a Business Day, such
payment may be made on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of interest or Fees, if applicable.

SECTION 2.20. Taxes. (a) Any and all payments by or on account of any obligation of any
Borrower or any other Loan Party hereunder or under any other Loan Document shall be made free and
clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if any
Borrower or any other Loan Party shall be required to deduct any Indemnified Taxes or Other Taxes
from such payments, then (i) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums payable under this
Section) the Administrative Agent, Lender 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) such Borrower or
such Loan Party shall make such deductions and (iii) such Borrower or such Loan Party shall pay the
full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The Borrowers 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 any Borrower or any other Loan
Party hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes
imposed or asserted on or attributable to amounts payable under this Section) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or liability delivered to
the Borrowers by a Lender or the Issuing Bank, or by the Administrative Agent on behalf of itself
or a Lender, shall be conclusive absent manifest error.

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

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
under the law of the jurisdiction in which the Borrowers are located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement shall deliver to the
Borrowers (with a copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable law or reasonably
requested by the Borrowers as will permit such payments to be made without withholding or at a
reduced rate.

SECTION 2.21. Assignment of Commitments Under Certain Circumstances; Duty to Mitigate. (a)
In the event (i) any Lender or the Issuing Bank delivers a certificate requesting compensation
pursuant to Section 2.14, (ii) any Lender or the Issuing Bank delivers a notice described in
Section 2.15, (iii) any Borrower is required to pay any additional amount to any Lender or the
Issuing Bank or any Governmental Authority on account of any Lender or the Issuing Bank pursuant to
Section 2.20 or (iv) any Lender refuses to consent to any amendment, waiver or other modification
of any Loan Document requested by Parent or the Borrowers that requires the consent of a greater
percentage of the Lenders than the Required Lenders and such amendment, waiver or other
modification is consented to by the Required Lenders, Parent may, at its sole expense and effort
(including with respect to the processing and recordation fee referred to in Section 9.04(b)), upon
notice to such Lender or the Issuing Bank and the Administrative Agent, require such Lender or the
Issuing Bank to transfer and assign, without recourse (in accordance with and subject to the
restrictions contained in Section 9.04), all of its interests, rights and obligations under this
Agreement (or, in the case of clause (iv) above, all of its interests, rights and obligation with
respect to the Class of Loans or Commitments that is the subject of the related consent, amendment,
waiver or other modification) to an assignee that shall assume such assigned obligations (which
assignee may be another Lender, if a Lender accepts such assignment); provided that (x) such
assignment shall not conflict with any law, rule or regulation or order of any court or other
Governmental Authority having jurisdiction, (y) Parent shall have received the prior written
consent of the Administrative Agent (and, if a Revolving Credit Commitment is being assigned, of
the Issuing Bank and the Swingline Lender), which consent shall not unreasonably be withheld, and
(z) the Borrowers or such assignee shall have paid to the affected Lender or the Issuing Bank in
immediately available funds an amount equal to the sum of the principal of and interest accrued to
the date of such payment on the outstanding Loans or L/C Disbursements of such Lender or the
Issuing Bank, respectively, plus all Fees and other amounts accrued for the account of such Lender
or the Issuing Bank hereunder (including any amounts under Sections 2.14 and 2.16); provided
further that, if prior to any such transfer and assignment the circumstances or event that resulted
in such Lender’s or the Issuing Bank’s claim for compensation under Section 2.14 or notice under
Section 2.15 or the amounts paid pursuant to Section 2.20, as the case may be, cease to cause such
Lender or the Issuing Bank to suffer increased costs or reductions in amounts received or
receivable or reduction in return on capital, or cease to have the consequences specified in
Section 2.15, or cease to result in amounts being payable under Section 2.20, as the case may be
(including as a result of any action taken by such Lender or the Issuing Bank pursuant to paragraph
(b) of this Section), or if such Lender or the Issuing Bank shall waive its right to claim further
compensation under Section 2.14 in respect of such circumstances or event or shall withdraw its
notice under Section 2.15 or shall waive its right to further payments under Section 2.20 in
respect of such circumstances or event or shall consent to the proposed amendment, waiver, consent
or other modification, as the case may be, then such Lender or the Issuing Bank shall not
thereafter be required to make any such transfer and assignment hereunder. Each Lender hereby
grants to the Administrative Agent an irrevocable power of attorney (which power is coupled with an
interest) to execute and deliver, on behalf of such Lender as assignor, any Assignment and
Acceptance necessary to effectuate any assignment of such Lender’s interests hereunder in the
circumstances contemplated by this paragraph.

(b) If (i) any Lender or the Issuing Bank shall request compensation under Section 2.14, (ii)
any Lender or the Issuing Bank delivers a notice described in Section 2.15 or (iii) any Borrower is
required to pay any additional amount to any Lender or the Issuing Bank or any Governmental
Authority on account of any Lender or the Issuing Bank, pursuant to Section 2.20, then such Lender
or the Issuing Bank shall use reasonable efforts (which shall not require such Lender or the
Issuing Bank to incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any
action inconsistent with its internal policies or legal or regulatory restrictions or suffer any
disadvantage or burden deemed by it to be significant) (x) to file any certificate or document
reasonably requested in writing by any applicable Borrower or (y) to assign its rights and delegate
and transfer its obligations hereunder to another of its offices, branches or affiliates, if such
filing or assignment would reduce its claims for compensation under Section 2.14 or enable it to
withdraw its notice pursuant to Section 2.15 or would reduce amounts payable pursuant to Section
2.20, as the case may be, in the future. The Borrowers hereby agree to pay all reasonable costs
and expenses incurred by any Lender or the Issuing Bank in connection with any such filing or
assignment, delegation and transfer.

SECTION 2.22. Swingline Loans. (a) Swingline Commitment. Subject to the terms and
conditions and relying upon the representations and warranties herein set forth, the Swingline
Lender agrees to make loans to the Borrowers at any time and from time to time after the Closing
Date and until the earlier of the Revolving Credit Maturity Date and the termination of the
Revolving Credit Commitments, in an aggregate principal amount at any time outstanding that will
not result in (i) the aggregate principal amount of all Swingline Loans exceeding $10,000,000 or
(ii) the Aggregate Revolving Credit Exposure, after giving effect to any Swingline Loan, exceeding
the Total Revolving Credit Commitment. Each Swingline Loan shall be in a principal amount that is
an integral multiple of $500,000 and not less than $1,000,000. The Swingline Commitment may be
terminated or reduced from time to time as provided herein. Within the foregoing limits, the
Borrowers may borrow, pay or prepay and reborrow Swingline Loans hereunder, subject to the terms,
conditions and limitations set forth herein.

(b) Swingline Loans. The applicable Borrower shall notify the Administrative Agent by fax, or
by telephone (promptly confirmed by fax), not later than 12:00 noon, New York City time, on the day
of a proposed Swingline Loan. Such notice shall be delivered on a Business Day, shall be
irrevocable and shall refer to this Agreement and shall specify the requested date (which shall be
a Business Day) and amount of such Swingline Loan and the wire transfer instructions for the
account of such Borrower to which the proceeds of the Swingline Loan should be transferred. The
Administrative Agent will promptly advise the Swingline Lender of any notice received from a
Borrower pursuant to this paragraph. The Swingline Lender shall make each Swingline Loan by wire
transfer to the account specified in such request.

(c) Prepayment. The Borrowers shall have the right at any time and from time to time to
prepay any Swingline Loan, in whole or in part, upon giving written or fax notice (or telephone
notice promptly confirmed by written or fax notice) to the Swingline Lender and to the
Administrative Agent before 12:00 noon, New York City time, on the date of prepayment at the
Swingline Lender’s address for notices specified on Schedule 2.01.

(d) Interest. Each Swingline Loan shall be an ABR Loan and, subject to the provisions of
Section 2.07, shall bear interest as provided in Section 2.06(a).

(e) Participations. The Swingline Lender may by written notice given to the Administrative
Agent not later than 11:00 a.m., New York City time, on any Business Day require the Revolving
Credit Lenders to acquire participations on such Business Day in all or a portion of the Swingline
Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which
Revolving Credit Lenders will participate. The Administrative Agent will, promptly upon receipt of
such notice, give notice to each Revolving Credit Lender, specifying in such notice such Lender’s
Pro Rata Percentage of such Swingline Loan or Loans. In furtherance of the foregoing, each
Revolving Credit Lender hereby absolutely and unconditionally agrees, upon receipt of notice as
provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such
Revolving Credit Lender’s Pro Rata Percentage of such Swingline Loan or Loans. Each Revolving
Credit Lender acknowledges and agrees that its obligation to acquire participations in Swingline
Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including the occurrence and continuance of a Default or an Event of
Default, and that each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever. Each Revolving Credit Lender shall comply with its obligation under this
paragraph by wire transfer of immediately available funds, in the same manner as provided in
Section 2.02(c) with respect to Loans made by such Lender (and Section 2.02(c) shall apply, mutatis
mutandis, to the payment obligations of the Lenders) and the Administrative Agent shall promptly
pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative
Agent shall notify the Borrowers of any participations in any Swingline Loan acquired pursuant to
this paragraph and thereafter payments in respect of such Swingline Loan shall be made to the
Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender
from any Borrower (or other party on behalf of any Borrower) in respect of a Swingline Loan after
receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be
promptly remitted to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made
their payments pursuant to this paragraph and to the Swingline Lender, as their interests may
appear. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not
relieve any Borrower (or other party liable for obligations of any Borrower) of any default in the
payment thereof.

SECTION 2.23. Letters of Credit. (a) General. The Borrowers may request the issuance of
Letters of Credit, in form reasonably acceptable to the Administrative Agent and the Issuing Bank,
at any time and from time to time while the L/C Commitment remains in effect. This Section shall
not be construed to impose an obligation upon the Issuing Bank to issue any Letter of Credit that
is inconsistent with the terms and conditions of this Agreement.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. In order to
request the issuance of a Letter of Credit (or to amend, renew or extend an existing Letter of
Credit), the applicable Borrower shall hand deliver or fax to the Issuing Bank and the
Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal
or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of
Credit to be amended, renewed or extended, the date of issuance, amendment, renewal or extension,
the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this
Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and
such other information as shall be necessary to prepare such Letter of Credit. A Letter of Credit
shall be issued, amended, renewed or extended only if, and upon issuance, amendment, renewal or
extension of each Letter of Credit each Borrower shall be deemed to represent and warrant that,
after giving effect to such issuance, amendment, renewal or extension (i) the L/C Exposure shall
not exceed $25,000,000 and (ii) the Aggregate Revolving Credit Exposure shall not exceed the Total
Revolving Credit Commitment.

(c) Expiration Date. Each Letter of Credit shall expire at the close of business on the
earlier of the date one year after the date of the issuance of such Letter of Credit and the date
that is five Business Days prior to the Revolving Credit Maturity Date, unless such Letter of
Credit expires by its terms on an earlier date; provided, however, that a Letter of Credit may,
upon the request of the applicable Borrower, include a provision whereby such Letter of Credit
shall be renewed automatically for additional consecutive periods of 12 months or less (but not
beyond the date that is five Business Days prior to the Revolving Credit Maturity Date) unless the
Issuing Bank notifies the beneficiary thereof at least 30 days prior to the then-applicable
expiration date that such Letter of Credit will not be renewed.

(d) Participations. By the issuance of a Letter of Credit, and without any further action on
the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Revolving
Credit Lender, and each such Lender hereby acquires from the Issuing Bank, a participation in such
Letter of Credit equal to such Lender’s Pro Rata Percentage of the aggregate amount available to be
drawn under such Letter of Credit, effective upon the issuance of such Letter of Credit. In
consideration and in furtherance of the foregoing, each Revolving Credit Lender hereby absolutely
and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank,
such Lender’s Pro Rata Percentage of each L/C Disbursement made by the Issuing Bank and not
reimbursed by any Borrower (or, if applicable, another party pursuant to its obligations under any
other Loan Document) forthwith on the date due as provided in Section 2.02(f). Each Revolving
Credit Lender acknowledges and agrees that its obligation to acquire participations pursuant to
this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including the occurrence and continuance of a Default or
an Event of Default, and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any L/C Disbursement in respect of a Letter
of Credit, the applicable Borrower shall pay to the Administrative Agent an amount equal to such
L/C Disbursement on the Business Day on which such Borrower shall have received notice from the
Issuing Bank that payment of such draft will be made, or, if such Borrower shall have received such
notice later than 10:00 a.m., New York City time, on any Business Day, not later than 10:00 a.m.,
New York City time, on the immediately following Business Day.

(f) Obligations Absolute. Each Borrower’s obligations to reimburse L/C Disbursements as
provided in paragraph (e) of this Section 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 any Loan
Document, or any term or provision therein;

(ii) any amendment or waiver of or any consent to departure from all or any of the
provisions of any Letter of Credit or any Loan Document;

(iii) the existence of any claim, setoff, defense or other right that such Borrower,
any other party guaranteeing, or otherwise obligated with, such Borrower, any Subsidiary or
other Affiliate thereof or any other person may at any time have against the beneficiary
under any Letter of Credit, the Issuing Bank, the Administrative Agent or any Lender or any
other person, whether in connection with this Agreement, any other Loan Document or any
other related or unrelated agreement or transaction;

(iv) any draft or other document presented under a Letter of Credit proving to be
forged, fraudulent, invalid or insufficient in any respect or any statement therein being
untrue or inaccurate in any respect;

(v) 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; and

(vi) any other act or omission to act or delay of any kind of the Issuing Bank, any
Lender, the Administrative Agent or any other person or any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for the
provisions of this Section, constitute a legal or equitable discharge of such Borrower’s
obligations hereunder.

Without limiting the generality of the foregoing, it is expressly understood and agreed that
the absolute and unconditional obligation of each Borrower hereunder to reimburse L/C Disbursements
will not be excused by the gross negligence or willful misconduct of the Issuing Bank. The
foregoing shall not, however, be construed to excuse the Issuing Bank from liability to a Borrower
to the extent of any direct damages (as opposed to consequential damages, claims in respect of
which are hereby waived by each Borrower to the extent permitted by applicable law) suffered by
such Borrower that are caused by the Issuing Bank’s gross negligence or willful misconduct in
determining whether drafts and other documents presented under a Letter of Credit comply with the
terms thereof. It is understood that the Issuing Bank may accept documents that appear on their
face to be in order, without responsibility for further investigation, regardless of any notice or
information to the contrary and, in making any payment under any Letter of Credit (i) the Issuing
Bank’s exclusive reliance on the documents presented to it under such Letter of Credit as to any
and all matters set forth therein, including reliance on the amount of any draft presented under
such Letter of Credit, whether or not the amount due to the beneficiary thereunder equals the
amount of such draft and whether or not any document presented pursuant to such Letter of Credit
proves to be insufficient in any respect, if such document on its face appears to be in order, and
whether or not any other statement or any other document presented pursuant to such Letter of
Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in
any respect whatsoever and (ii) any noncompliance in any immaterial respect of the documents
presented under such Letter of Credit with the terms thereof shall, in each case, be deemed not to
constitute gross negligence or willful misconduct of the Issuing Bank.

(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 as promptly as possible give telephonic notification, confirmed by fax, to the
Administrative Agent and the applicable Borrower 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 such Borrower of its obligation to reimburse the
Issuing Bank and the Revolving Credit Lenders with respect to any such L/C Disbursement.

(h) Interim Interest. If the Issuing Bank shall make any L/C Disbursement in respect of a
Letter of Credit, then, unless the applicable Borrower shall reimburse such L/C Disbursement in
full on such date, the unpaid amount thereof shall bear interest for the account of the Issuing
Bank, for each day from and including the date of such L/C Disbursement to but excluding the
earlier of the date of payment by such Borrower or the date on which interest shall commence to
accrue thereon as provided in Section 2.02(f), at the rate per annum that would apply to such
amount if such amount were an ABR Revolving Loan.

(i) Resignation or Removal of the Issuing Bank. The Issuing Bank may resign at any time by
giving 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrowers,
and may be removed at any time by Parent by notice to the Issuing Bank, the Administrative Agent
and the Lenders. Upon the acceptance of any appointment as the Issuing Bank hereunder by a Lender
that shall agree to serve as successor Issuing Bank, such successor shall succeed to and become
vested with all the interests, rights and obligations of the retiring Issuing Bank and the retiring
Issuing Bank shall be discharged from its obligations to issue additional Letters of Credit
hereunder. At the time such removal or resignation shall become effective, the Borrowers shall pay
all unpaid fees accrued pursuant to clause (ii) of Section 2.05(c). The acceptance of any
appointment as the Issuing Bank hereunder by a successor Lender shall be evidenced by an agreement
entered into by such successor, in a form satisfactory to Parent and the Administrative Agent, and,
from and after the effective date of such agreement, (i) such successor Lender shall have all the
rights and obligations of the previous Issuing Bank under this Agreement and the other Loan
Documents and (ii) references herein and in the other Loan Documents 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 resignation or removal of
the Issuing Bank hereunder, the retiring Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of the Issuing Bank under this Agreement and the
other Loan Documents with respect to Letters of Credit issued by it prior to such resignation or
removal, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If any Event of Default shall occur and be continuing, the
Borrowers shall, on the Business Day they receive notice from the Administrative Agent or the
Required Lenders (or, if the maturity of the Loans has been accelerated, Revolving Credit Lenders
holding participations in outstanding Letters of Credit representing greater than 50% of the
aggregate undrawn amount of all outstanding Letters of Credit) thereof and of the amount to be
deposited, deposit in an account with the Collateral Agent, for the benefit of the Revolving Credit
Lenders, an amount in cash equal to the L/C Exposure as of such date. Such deposit shall be held
by the Collateral Agent as collateral for the payment and performance of the Obligations. The
Collateral 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
in Permitted Investments, which investments shall be made at the option and sole discretion of the
Collateral Agent, such deposits shall not bear interest. Interest or profits, if any, on such
investments shall accumulate in such account. Moneys in such account shall (i) automatically be
applied by the Administrative Agent to reimburse the Issuing Bank for L/C Disbursements for which
it has not been reimbursed, (ii) be held for the satisfaction of the reimbursement obligations of
the Borrowers for the L/C Exposure at such time and (iii) if the maturity of the Loans has been
accelerated (but subject to the consent of Revolving Credit Lenders holding participations in
outstanding Letters of Credit representing greater than 50% of the aggregate undrawn amount of all
outstanding Letters of Credit), be applied to satisfy the Obligations. If the Borrowers are
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
Borrowers within three Business Days after all Events of Default have been cured or waived.

SECTION 2.24. Increase in Term Loan Commitments. (a) Any Borrower may, by written notice to
the Administrative Agent from time to time, request Incremental Term Loan Commitments in an amount
not to exceed the Incremental Term Loan Amount from one or more financial institutions, which may
include any existing Lender; provided that each Incremental Term Lender, if not already a Lender
hereunder, shall be subject to the approval of the Administrative Agent (which approval shall not
be unreasonably withheld). Such notice shall set forth (i) the amount of the Incremental Term Loan
Commitments being requested (which shall be in minimum increments of $1,000,000 and a minimum
amount of $5,000,000 or equal to the remaining Incremental Term Loan Amount), (ii) the date on
which Loans are to be made pursuant to such Incremental Term Loan Commitments are requested (which
shall not be less than 10 Business Days or more than 60 days after the date of such notice) and
(iii) whether such Incremental Term Loan Commitments are to be commitments to make loans with terms
identical to the Initial Term Loans or commitments to make term loans with terms different from the
Initial Term Loans (“Other Term Loans”).

(b) The applicable Borrower and each Incremental Term Lender shall execute and deliver to the
Administrative Agent an Incremental Term Loan Assumption Agreement and such other documentation as
the Administrative Agent shall reasonably specify to evidence the Incremental Term Loan Commitment
of such Incremental Term Lender. Each Incremental Term Loan Assumption Agreement shall specify the
terms of the Incremental Term Loans to be made thereunder; provided, however, that, without the
prior written consent of Lenders holding a majority in interest of the outstanding Loans and
Commitments of each adversely affected Class of Term Loans, (i) the final maturity date of any
Other Term Loans shall be no earlier than (x) the final maturity date of any other Class of Term
Loans and (y) if the initial yield (determined as provided below) on such Other Term Loans exceeds
the Applicable Percentage for Eurodollar Term Loans of any Class, the date falling six months after
the final maturity date of each such adversely affected Class; (ii) the average life to maturity of
any Other Term Loans shall be no shorter than (x) the average life to maturity of any other Class
of Term Loans and (y) if the initial yield (determined as provided below) on such Other Term Loans
exceeds the Applicable Percentage at the time in effect for Eurodollar Term Loans of any Class, six
months longer than the average life to maturity of each such adversely affected Class; and (iii) if
the initial yield on any Other Term Loans (as determined by the Administrative Agent to be equal to
the sum of (x) the Eurodollar spread on the Other Term Loans and (y) if the Other Term Loans are
initially made at a discount or the lenders making the same receive a fee from Parent or any
Subsidiary for doing so (the amount of such discount or fee, expressed as a percentage of the Other
Term Loans, being referred to herein as “OID”), the amount of such OID divided by the lesser of (A)
the average life to maturity of such Other Term Loans and (B) four) exceeds by more than 50 basis
points (the amount of such excess above 50 basis points being referred to herein as the “Yield
Differential”) the Applicable Percentages from time to time in effect for such other Class of Term
Loans, then the Applicable Percentage for each adversely affected Class of Term Loans shall
automatically be increased by the Yield Differential, effective upon the making of the Other Term
Loans. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each
Incremental Term Loan Assumption Agreement. Each of the parties hereto hereby agrees that, upon
the effectiveness of any Incremental Term Loan Assumption Agreement, this Agreement shall be deemed
amended to the extent (but only to the extent) necessary to reflect the existence and terms of the
Incremental Term Loan Commitment evidenced thereby and any increase to the Applicable Percentages
required by the foregoing provisions of this paragraph. If the Administrative Agent shall so
elect, any such deemed amendment shall be memorialized in a writing satisfactory to the
Administrative Agent and Parent and furnished to the other parties hereto.

(c) Notwithstanding the foregoing, no Incremental Term Loan Commitment shall become effective
under this Section unless (i) on the date of such effectiveness, the conditions set forth in
paragraphs (b) and (c) of Section 4.01 shall be satisfied and the Administrative Agent shall have
received a certificate to that effect dated such date and executed by a Financial Officer of
Parent, (ii) the Administrative Agent shall have received (with sufficient copies for each of the
Incremental Term Lenders) legal opinions, board resolutions and other closing certificates and
documentation consistent with those delivered on the Closing Date under Article IV and (iii)
Parent and the Borrowers would be in Pro Forma Compliance after giving effect to such Incremental
Term Loan Commitment and the Loans to be made thereunder and the application of the proceeds
therefrom as if made and applied on such date.

(d) Each of the parties hereto hereby agrees that the Administrative Agent may take any and
all action as may be reasonably necessary to ensure that all Incremental Term Loans (other than
Other Term Loans), when originally made, are included in each Borrowing of outstanding Loans on a
pro rata basis. This may be accomplished at the discretion of the Administrative Agent by
requiring each outstanding Eurodollar Borrowing to be converted into an ABR Borrowing on the date
of each Incremental Term Loan, or by allocating a portion of each Incremental Term Loan to each
outstanding Eurodollar Borrowing on a pro rata basis, even though as a result thereof such
Incremental Term Loan may effectively have a shorter Interest Period than the Loans included in the
Borrowing of which they are a part (and notwithstanding any other provision of this Agreement that
would prohibit such an initial Interest Period). Any conversion of Eurodollar Loans to ABR Loans
made pursuant to the preceding sentence shall be subject to Section 2.16. If any Incremental Term
Loan is to be allocated to an existing Interest Period for a Eurodollar Borrowing then, subject to
Section 2.07, the interest rate applicable to such Incremental Term Loan for the remainder of such
Interest Period shall equal the Adjusted LIBO Rate for a period approximately equal to the
remainder of such Interest Period (as determined by the Administrative Agent two Business Days
before the date such Incremental Term Loan is made) plus the Applicable Percentage.

of operations and cash flows of Parent and its consolidated Subsidiaries and of such consolidated
Subsidiaries, as the case may be, as of such dates and for such periods. Such balance sheets and
the notes thereto disclose all material liabilities, direct or contingent, of Parent and its
consolidated Subsidiaries and of such consolidated Subsidiaries, as the case may be, as of the
dates thereof.

(b) Parent has heretofore delivered to the Lenders its unaudited pro forma consolidated
balance sheet as of December 31, 2003, and the related statements of income, changes in member’s
equity and cash flows prepared giving effect to the Transactions as if they had occurred, with
respect to such balance sheet, on such date and, with respect to such other financial statements,
on the first day of the twelve-month period ending on such date. Such pro forma financial
statements have been prepared in good faith by Parent, based on the assumptions used to prepare the
pro forma financial information contained in the Confidential Information Memorandum (which
assumptions are believed by Parent and the Borrowers on the date hereof and on the Closing Date to
be reasonable), are based on the best information available to Parent and the Borrowers as of the
date of delivery thereof, accurately reflect all adjustments required to be made to give effect to
the Transactions and present fairly on a pro forma basis the estimated consolidated financial
position of Parent and its consolidated Subsidiaries as of such date and for such period, assuming
that the Transactions had actually occurred at such date or at the beginning of such period, as the
case may be.

SECTION 3.06. No Material Adverse Change. No event, change or condition has occurred that has
had, or would be materially likely to have, a material adverse effect on the business, assets,
operations, financial condition or prospects of Parent and the Subsidiaries, taken as a whole,
since December 31, 2003.

SECTION 3.07. Title to Properties; Possession Under Leases. (a) Each of Parent and the
Subsidiaries has good and marketable title to, or valid leasehold interests in, all its material
properties and assets (including all Mortgaged Property), except for minor defects in title that do
not interfere with its ability to conduct its business as currently conducted or to utilize such
properties and assets for their intended purposes. All such material properties and assets are
free and clear of Liens, other than Liens expressly permitted by Section 6.02.

(b) Each of Parent and the Subsidiaries has complied in all material respects with all
obligations under all material leases to which it is a party and all such leases are in full force

other contractual right to sell, assign or otherwise dispose of any Mortgaged Property or any
interest therein.

SECTION 3.08. Subsidiaries. Schedule 3.08 sets forth as of the First Amendment Effective Date
a list of all Subsidiaries and the percentage ownership interest of Parent and each Subsidiary
therein. The Subsidiary Guarantors, the Insurance Subsidiaries, the Immaterial Subsidiaries and
the HMO Subsidiaries listed on Schedule 3.08 are designated as such. The shares of capital stock
or other ownership interests in the Subsidiaries set forth on Schedule 3.08 are fully paid and
non-assessable and are owned by Parent or a Borrower, directly or indirectly, free and clear of all
Liens (other than Liens created under the Security Documents and, with respect to the Seller Note
Pledged Stock, if any, Liens under the Seller Note and any documents related thereto).

SECTION 3.09. Litigation; Compliance with Laws. (a) Except as set forth on Schedule 3.09,
there are no actions, suits or proceedings at law or in equity or by or before any Governmental
Authority now pending or, to the knowledge of Parent or any Borrower, threatened against or
affecting Parent or any Subsidiary or any business, property or rights of any such person (i) that
involve any Loan Document or the Credit Transactions or (ii) that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

(b) Since the date of this Agreement, there has been no change in the status of the matters
disclosed on Schedule 3.09 that, individually or in the aggregate, has resulted in, or materially
increased the likelihood of, a Material Adverse Effect.

(c) None of Parent or any Subsidiary or any of their respective material properties or assets
is in violation of, nor will the continued operation of their material properties and assets as

affecting the Mortgaged Property, or is in default with respect to any judgment, writ, injunction,
decree or order of any Governmental Authority, where such violation or default could reasonably be
expected to result in a Material Adverse Effect. Without limiting the foregoing, (i) none of

by any of the foregoing, could reasonably be expected to have criminal culpability or to be
excluded from participation in any Medical Reimbursement Program for corporate or individual act or
omission to act, (ii) no officer continues to be employed by Parent or any Subsidiary who could
reasonably be expected to have individual culpability for matters under investigation by the OIG or

of responsibility related to those activities under challenge by the OIG or such other Governmental
Authority, and (iii) current billing policies, arrangements, protocols and instructions of each of
Parent and the Subsidiaries comply in all material respects with requirements of Medical
Reimbursement Programs and are administered by properly trained personnel. To the knowledge of
Parent or any Borrower, none of Parent or any Subsidiary, nor any of their respective officers,
directors or employees, have engaged in any activities that constitute prohibited acts of fraud
under Medicare Regulations or under Medicaid Regulations.

(d) All material certificates of occupancy and material permits are in effect for each
Mortgaged Property as currently constructed to the extent required by applicable law, and true and
complete copies of such certificates of occupancy have been delivered to the Collateral Agent as
mortgagee with respect to each Mortgaged Property.

or instrument or subject to any corporate restriction that has resulted or could reasonably be
expected to result in a Material Adverse Effect.

(b) None of Parent or any Subsidiary is in default in any manner under any provision of any
indenture or other agreement or instrument evidencing Indebtedness, or any other material agreement

be bound, where such default could reasonably be expected to result in a Material Adverse Effect.

SECTION 3.11. Federal Reserve Regulations. (a) None of Parent or any Subsidiary is engaged
principally, or as one of its important activities, in the business of extending credit for the
purpose of buying or carrying Margin Stock.

(b) No part of the proceeds of any Loan or any Letter of Credit will be used, whether directly
or indirectly, and whether immediately, incidentally or ultimately, for any purpose that entails a
violation of, or that is inconsistent with, the provisions of the Regulations of the Board,
including Regulation T, U or X.

SECTION 3.12. Investment Company Act; Public Utility Holding Company Act. None of Parent or
any Subsidiary is (a) an “investment company” as defined in, or subject to regulation under, the

filed all Federal, state, local and foreign tax returns or materials required to have been filed by
it and has paid or caused to be paid all taxes due and payable by it and all assessments received
by it, except taxes that are being contested in good faith by appropriate proceedings and for which
Parent or such Subsidiary, as applicable, shall have set aside on its books adequate reserves.

SECTION 3.14. No Material Misstatements. None of (a) the Confidential Information Memorandum,
(b) the Amendment Confidential Information Memorandum or (c) any other information, report,
financial statement, exhibit or schedule furnished by or on behalf of Parent or any Borrower to the
Administrative Agent or any Lender in connection with the negotiation of any Loan Document or
included therein or delivered pursuant thereto contained, contains or will contain any material
misstatement of fact or omitted, omits or will omit to state any material fact necessary to make
the statements therein, in the light of the circumstances under which they were, are or will be
made, not misleading; provided that to the extent any such information, report, financial
statement, exhibit or schedule was based upon or constitutes a forecast or projection, each of
Parent and the Borrowers represents only that it acted in good faith and utilized reasonable
assumptions and due care in the preparation of such information, report, financial statement,
exhibit or schedule.

SECTION 3.15. Employee Benefit Plans. Each of Parent and its ERISA Affiliates is in
compliance with the applicable provisions of ERISA and the Code and the regulations and published
interpretations thereunder, except to the extent the failure to comply could not, individually or
in the aggregate, reasonably be expected to result in a Material Adverse Effect. No ERISA Event
has occurred or is reasonably expected to occur that, when taken together with all other such ERISA
Events, could reasonably be expected to result in a Material Adverse Effect. The present value of
all benefit liabilities under each Plan (based on the assumptions used for purposes of Statement of
Financial Accounting Standards No. 87) did not, as of the last annual valuation date applicable
thereto, exceed by more than $3,000,000 the fair market value of the assets of such Plan, and the
present value of all benefit liabilities of all underfunded Plans (based on the assumptions used
for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the last annual
valuation dates applicable thereto, exceed by more than $8,000,000 the fair market value of the
assets of all such underfunded Plans.

SECTION 3.16. Environmental Matters. (a) Except as set forth in Schedule 3.16 and except

Liability, (iii) has received notice of any claim with respect to any Environmental Liability or

disclosed on Schedule 3.16 that, individually or in the aggregate, has resulted in, or materially
increased the likelihood of, a Material Adverse Effect.

SECTION 3.17. Insurance. Schedule 3.17 sets forth a true, complete and correct description of
all insurance maintained by or on behalf of Parent and the Subsidiaries as of the First Amendment
Effective Date. As of the First Amendment Effective Date, such insurance is in full force and
effect and all premiums have been duly paid. Except for self-insurance on terms consistent with
industry practice, the properties of Parent and the Subsidiaries are insured in all material
respects with financially sound and reputable insurance companies not Affiliates of Parent, in such
amounts, and with such deductibles and covering such risks, as are customarily carried by companies
engaged in similar businesses and owning similar properties in localities where Parent or the
applicable Subsidiary operates.

SECTION 3.18. Security Documents. (a) The Guarantee and Collateral Agreement, upon execution
and delivery thereof by the parties thereto, will create in favor of the Collateral Agent, for the
ratable benefit of the Secured Parties, a legal, valid and enforceable security interest in the
Collateral (as defined in the Guarantee and Collateral Agreement) and the proceeds thereof and (i)
when the Pledged Collateral (as defined in the Guarantee and Collateral Agreement) is delivered to
the Collateral Agent, the Guarantee and Collateral Agreement shall constitute a fully perfected
first priority Lien on, and security interest in, all right, title and interest of the Loan Parties
in such Pledged Collateral, in each case prior and superior in right to any other person, and (ii)
when financing statements in appropriate form are filed in the offices specified on Schedule
3.18(a), the Lien created under the Guarantee and Collateral Agreement will constitute a fully
perfected Lien on, and security interest in, all right, title and interest of the Loan Parties in
such Collateral (other than Intellectual Property, as defined in the Guarantee and Collateral
Agreement), in each case prior and superior in right to any other person, other than with respect
to Liens expressly permitted by Section 6.02.

(b) Upon the recordation of the Guarantee and Collateral Agreement with the United States
Patent and Trademark Office and the United States Copyright Office, together with the financing
statements in appropriate form filed in the offices specified on Schedule 3.18(a), the Guarantee
and Collateral Agreement shall constitute a fully perfected Lien on, and security interest in, all
right, title and interest of the Loan Parties in the Intellectual Property (as defined in the
Guarantee and Collateral Agreement) in which a security interest may be perfected by filing in the
United States of America and its territories and possessions, in each case prior and superior in
right to any other person (it being understood that subsequent recordings in the United States
Patent and Trademark Office and the United States Copyright Office may be necessary to perfect a
Lien on registered trademarks and patents, trademark and patent applications and registered
copyrights acquired by the Loan Parties after the date hereof).

(c) The Mortgages, if any, are effective to create in favor of the Collateral Agent, for the
ratable benefit of the Secured Parties, a legal, valid and enforceable Lien on all of the Loan
Parties’ right, title and interest in and to the Mortgaged Property thereunder and the proceeds
thereof, and when such Mortgages are filed in the proper real estate filing offices, such Mortgages
shall constitute a fully perfected Lien on, and security interest in, all right, title and interest
of the Loan Parties in such Mortgaged Property and the proceeds thereof, in each case prior and
superior in right to any other person, other than with respect to the rights of persons pursuant to
Liens expressly permitted by Section 6.02.

SECTION 3.19. Location of Real Property and Leased Premises.

SECTION 3.20. Labor Matters. As of the date hereof and the Closing Date, there are no
strikes, lockouts or slowdowns against Parent or any Subsidiary pending or, to the knowledge of
Parent or any Borrower, threatened. The hours worked by and payments made to employees of Parent
and the Subsidiaries have not been in violation of the Fair Labor Standards Act or any other
applicable Federal, state, local or foreign law dealing with such matters, where such violation
could reasonably be expected to result in a Material Adverse Effect. All payments due from Parent
or any Subsidiary, or for which any claim may be made against Parent or any Subsidiary, on account
of wages and employee health and welfare insurance and other benefits, have been paid or accrued as
a liability on the books of Parent or such Subsidiary, except where the failure to do so could not
reasonably be expected to result in a Material Adverse Effect. The consummation of the
Transactions will not give rise to any right of termination or right of renegotiation on the part
of any union under any collective bargaining agreement to which Parent or any Subsidiary is bound.

SECTION 3.21. Solvency. Immediately after the consummation of the Credit Transactions to
occur on the Closing Date and immediately following the making of each Loan and after giving effect
to the application of the proceeds of each Loan, (a) the fair value of the assets of each Loan
Party, at a fair valuation, will exceed its debts and liabilities, subordinated, contingent or

liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become
absolute and matured; (c) each Loan Party will be able to pay its debts and liabilities,
subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured;

Obligations and obligations under the Existing Credit Agreement, are, or will be, designated as

reasonably be expected to have a Material Adverse Effect, each of Parent and the Subsidiaries (i)
has obtained and maintains accreditation from one or more generally recognized accreditation
agencies where such accreditation is customary in the industry in which it is engaged; (ii) in the
case of each HMO Subsidiary, has entered into and maintains in good standing its contract with the
Centers for Medicare and Medicaid Services to be a Medicare Advantage Organization or such other
agreement to be able to provide managed health care services to Medicare or Medicaid; and (iii) has
taken all action to obtain, preserve and maintain each certificate of authority, license, permit,
authorization and other approval of any Governmental Authority required for the conduct of its
business, and all of such certificates, licenses, permits, authorizations or approvals are in full
force and effect and have not been revoked or suspended or otherwise limited. In furtherance of
the foregoing, each of Parent and the Subsidiaries has taken all action to obtain, preserve and
maintain with respect to each HMO Subsidiary and Insurance Subsidiary all certificates of
authority, licenses, permits, authorizations and other approvals required under the HMO Regulations
or other regulations issued by the applicable Governmental Authority, including approvals required

available under the HMO Regulations or other regulations issued by the applicable Governmental
Authority, and all of such certificates, licenses, permits, authorizations or approvals are in full
force and effect and have not been revoked or suspended or otherwise limited.

failure to do so could not reasonably be expected to have a Material Adverse Effect, each of Parent
and the Subsidiaries has timely filed (a) all reports and other filings required to be filed in
connection with the Medicare and Medicaid programs, and all such reports and filings are true and
complete in all material respects, and (b) all material reports, data and other information
required by any other Governmental Authority with authority to regulate it or its business or
operations in any manner. Except to the extent any such action could not reasonably be expected to
result in a Material Adverse Effect, (i) there are no claims, actions, proceedings or appeals
pending (and none of Parent or any Subsidiary has made any filing that would result in any claims,
actions, proceedings or appeals) before any Governmental Authority with respect to any Medicare or
Medicaid reports or claims filed by Parent or any Subsidiary on or before the date hereof, or with
respect to any adjustments, denials, recoupments or disallowances by any intermediary, carrier,
other insurer, commission, board or agency in connection with any cost reports or claims, and (ii)
no validation review, survey, inspection, audit, investigation or program integrity review related
to Parent or any Subsidiary has been conducted by any Governmental Authority or government
contractor in connection with the Medicare or Medicaid programs, and no such reviews are scheduled,
pending or, to the knowledge of Parent or any Borrower, threatened against or affecting Parent or
any Subsidiary.

approvals of all applicable Governmental Authorities as are required for the conduct of its
business as currently conducted and as proposed to be conducted, including licenses and contracts
with Medicare and Medicaid.

trained personnel.

(d) Maintain a compliance program for Parent and the Subsidiaries that (i) satisfies the
requirements therefor applicable to Medicare Advantage Organizations and (ii) is reasonably
designed to provide internal controls effective to promote adherence to, and prevent and detect any
material violation of, any applicable laws, rules and regulations and, in any event, includes
regular internal audits and monitoring to ensure compliance therewith and with all applicable laws,
rules and regulations.

SECTION 5.10. Further Assurances. Execute any and all further documents, financing
statements, agreements and instruments, and take all further action (including filing Uniform
Commercial Code and other financing statements, fixture filings, mortgages and deeds of trust and
preparation of all documentation relating to filings under the Assignment of Claims Act) that may
be required under applicable law, or that the Required Lenders, the Administrative Agent or the
Collateral Agent may reasonably request, to cause the Guarantee and Collateral Requirement to be
and remain satisfied and to effectuate the other transactions contemplated by the Loan Documents,
all at the expense of the Loan Parties. Without limiting the foregoing, Parent and each Borrower
will cause the Guarantee and Collateral Requirement to be satisfied with respect to (a) each
Subsidiary acquired or organized subsequent to the date hereof (other than any such Subsidiary that
is a Foreign Subsidiary, an Immaterial Subsidiary, an Insurance Subsidiary or an HMO Subsidiary
that has not Guaranteed any Indebtedness of Parent or any other Subsidiary), (b) each Subsidiary
that ceases to be an Immaterial Subsidiary, an Insurance Subsidiary or an HMO Subsidiary and (c)

each Borrower will, at their cost and expense, promptly secure the Obligations by pledging or
creating, or causing to be pledged or created, perfected security interests with respect to such of
its assets and properties as the Administrative Agent or the Required Lenders shall designate (it
being understood that it is the intent of the parties that the Obligations shall be secured, except
to the extent set forth in the definition of the term “Guarantee and Collateral Requirement,” by
substantially all the assets of Parent and the Subsidiaries, including real and other properties
acquired subsequent to the Closing Date). Parent and each Borrower agree to provide such evidence
as the Collateral Agent shall reasonably request as to the perfection and priority status of each
security interest and Lien created or intended to be created under the Security Documents. In
furtherance of the foregoing, Parent and each Borrower agree to give prompt notice to the
Administrative Agent of the acquisition by it or any of its subsidiaries of any real property (or
any interest in real property) having a value in excess of $250,000.

SECTION 5.11. Designation of Obligations; Matters Relating to the Seller Note. (a) In the
event that Parent or any Subsidiary shall at any time issue or have outstanding any Indebtedness
that by its terms is subordinated to any other Indebtedness of Parent or such Subsidiary, take all
actions as shall be necessary to cause the Obligations to constitute senior indebtedness (however
denominated) in respect of such subordinated Indebtedness and to enable the Lenders to have and
exercise any payment blockage or other remedies available or potentially available to holders of
senior indebtedness under the terms of such subordinated Indebtedness. In furtherance of the
foregoing, the Obligations are hereby designated as “senior indebtedness” and, if relevant, as
“designated senior indebtedness” in respect of all such subordinated Indebtedness (including
designation by WCGHM of the Obligations as “Senior Indebtedness” under the Seller Note) and are
further given all such other designations as shall be required under the terms of any such
subordinated Indebtedness in order that the Lenders may have and exercise any payment blockage or
other remedies available or potentially available to holders of senior Indebtedness under the terms
of such subordinated Indebtedness.

(b) In the case of WCGHM, promptly after the date hereof provide to the payee under the Seller
Note written notice of the designation of the Obligations as “Senior Indebtedness” under the Seller
Note, which notice shall include the address and fax number of the Administrative Agent set forth
in Section 9.01 (and, in the event such address or fax number shall change as contemplated by
Section 9.01, promptly inform the payee under the Seller Note of any such change); and promptly
after obtaining knowledge thereof, provide to the Administrative Agent notice of any change of the
address, fax number or other information set forth in the Seller Note with respect to the payee
thereunder.

ARTICLE VIII

Agents

(a) The Administrative Agent and the Collateral Agent.

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent
and the Collateral Agent (for purposes of this Article, the Administrative Agent and the Collateral
Agent are referred to collectively as the “Agents”) its agent and authorizes the Agents to take
such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms
of the Loan Documents, together with such actions and powers as are reasonably incidental thereto.
Without limiting the generality of the foregoing, the Agents are hereby expressly authorized to
execute any and all documents (including releases) with respect to the Collateral and the rights of
the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions
of this Agreement and the Security Documents.

The bank serving as the Administrative Agent and/or the Collateral Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and may exercise the
same as though it were not an Agent, and such bank and its Affiliates may accept deposits from,
lend money to and generally engage in any kind of business with Parent, any Borrower or any other
Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

Neither Agent shall have any duties or obligations except those expressly set forth in the
Loan Documents. Without limiting the generality of the foregoing, (a) neither Agent shall be
subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and
is continuing, (b) neither Agent shall have any duty to take any discretionary action or exercise
any discretionary powers, except discretionary rights and powers expressly contemplated hereby that
such Agent is instructed in writing to exercise by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as provided in Section
9.08), and (c) except as expressly set forth in the Loan Documents, neither Agent shall have any
duty to disclose, nor shall it be liable for the failure to disclose, any information relating to
Parent or any Subsidiary that is communicated to or obtained by the bank serving as Administrative
Agent and/or Collateral Agent or any of its Affiliates in any capacity. Neither Agent shall be
liable for any action taken or not taken by it with the consent or at the request of the Required
Lenders (or such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.08) or in the absence of its own gross negligence or willful
misconduct. Neither Agent shall be deemed to have knowledge of any Default unless and until
written notice thereof is given to such Agent by Parent, a Borrower or a Lender, and neither Agent
shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty
or representation made in or in connection with any Loan Document, (ii) the contents of any
certificate, report or other document delivered thereunder or in connection therewith, (iii) the
performance or observance of any of the covenants, agreements or other terms or conditions set
forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt
of items expressly required to be delivered to such Agent.

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

Each Agent may perform any and all its duties and exercise its rights and powers by or through
any one or more sub-agents appointed by it. Each Agent and any such sub-agent may perform any and
all its duties and exercise its rights and powers by or 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 each Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided for herein as well
as activities as Agent.

Subject to the appointment and acceptance of a successor Agent as provided below, either Agent
may resign at any time by notifying the Lenders, the Issuing Bank and the Borrowers. Upon any such
resignation, the Required Lenders shall have the right, subject, if no Event of Default shall have
occurred and be continuing, to the consent of the Borrowers (not to be unreasonably withheld), to
appoint a successor. If no successor shall have been so appointed by the Required Lenders and
shall have accepted such appointment within 30 days after the retiring Agent gives notice of its
resignation, then the retiring Agent may, subject, if no Event of Default shall have occurred and
be continuing, to the consent of the Borrowers (not to be unreasonably withheld), on behalf of the
Lenders and the Issuing Bank, appoint a successor Agent 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 Agent
hereunder by a successor, such successor shall succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Agent
shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers
and such successor. After an Agent’s resignation hereunder, the provisions of this Article and
Section 9.05 shall continue in effect for the benefit of such retiring Agent, its sub-agents and
their respective Related Parties in respect of any actions taken or omitted to be taken by any of
them while acting as Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Agents 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 Agents 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 or any other Loan
Document, any related agreement or any document furnished hereunder or thereunder.

(b) Other Agents.

None of the Lenders or other persons identified on the facing page or signature pages of this
Agreement as a “Syndication Agent” or “Documentation Agent” shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than, in the case of such
Lenders, those applicable to all Lenders as such. Without limiting the foregoing, none of the
Lenders or other persons so identified shall have or be deemed to have any fiduciary relationship
with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders or other persons so identified in deciding to enter into this Agreement or in taking or not
taking action hereunder.

shall be considered to have been relied upon by the Lenders and the Issuing Bank and shall survive
the making by the Lenders of the Loans and the issuance of Letters of Credit by the Issuing Bank,
regardless of any investigation made by the Lenders or the Issuing Bank or on their behalf, 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 or any other Loan Document is
outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have
not been terminated. The provisions of Sections 2.14, 2.16, 2.20 and 9.05 shall remain operative
and in full force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of the Loans, the
expiration of the Commitments, the expiration of any Letter of Credit, the invalidity or
unenforceability of any term or provision of this Agreement or any other Loan Document, or any
investigation made by or on behalf of the Administrative Agent, the Collateral Agent, any Lender or
the Issuing Bank.

SECTION 9.03. Binding Effect. This Agreement shall become effective when it shall have been
executed by each Borrower, Parent and 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.

SECTION 9.04. Successors and Assigns. (a) Whenever in this Agreement any of the parties
hereto is referred to, such reference shall be deemed to include the permitted successors and
assigns of such party; and all covenants, promises and agreements by or on behalf of the Borrowers,
Parent, the Administrative Agent, the Collateral Agent, the Issuing Bank or the Lenders that are
contained in this Agreement shall bind and inure to the benefit of their respective successors and
assigns.

(b) Each Lender may assign to one or more assignees all or a portion of its interests, rights
and obligations under this Agreement (including all or a portion of its Commitment and the Loans at
the time owing to it), with the prior written consent of the Administrative Agent (not to be
unreasonably withheld or delayed); provided, however, that (i) in the case of an assignment of a
Revolving Credit Commitment (other than an assignment to a Lender or an Affiliate of a Lender),
each of Parent, the Issuing Bank and the Swingline Lender must also give its prior written consent
to such assignment (which consent shall not be unreasonably withheld or delayed) (provided, that
the consent of Parent shall not be required to any such assignment during the continuance of any
Event of Default), (ii) the amount of the Commitment or Loans of the assigning Lender subject to
each such assignment (determined as of the date the Assignment and Acceptance with respect to such
assignment is delivered to the Administrative Agent) shall not be less than $1,000,000 (or, if
less, the entire remaining amount of such Lender’s Commitment or Loans of the relevant Class),
(iii) the parties to each such assignment shall execute and deliver to the Administrative Agent an
Assignment and Acceptance, together with a processing and recordation fee of $3,500, and (iv) the
assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire and all applicable tax forms. Upon acceptance and recording pursuant to paragraph
(e) of this Section, from and after the effective date specified in each Assignment and Acceptance,
(A) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by
such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement
and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case
of an Assignment and Acceptance covering all or the remaining portion of an 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, 2.16, 2.20 and 9.05, as well as to any
Fees accrued for its account and not yet paid).

(c) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder
and the assignee thereunder shall be deemed to confirm to and agree with each other and the other
parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial
owner of the interest being assigned thereby free and clear of any adverse claim and that its Term
Loan Commitment, Incremental Term Loan Commitment and Revolving Credit Commitment, and the
outstanding balances of its Term Loans and Revolving Loans, in each case without giving effect to
assignments thereof which have not become effective, are as set forth in such Assignment and
Acceptance, (ii) except as set forth in clause (i) above, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any statements, warranties
or representations made in or in connection with this Agreement, or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan
Document or any other instrument or document furnished pursuant hereto, or the financial condition
of Parent or any Subsidiary or the performance or observance by Parent or any Subsidiary of any of
its obligations under this Agreement, any other Loan Document or any other instrument or document
furnished pursuant hereto; (iii) such assignee represents and warrants that it is legally
authorized to enter into such Assignment and Acceptance; (iv) such assignee confirms that it has
received a copy of this Agreement, together with copies of the most recent financial statements
referred to in Section 3.05(a) or delivered pursuant to Section 5.04 and such other documents and
information as it has deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (v) such assignee will independently and without reliance upon the
Administrative Agent, the Collateral Agent, such assigning Lender or any other Lender and based on
such documents and information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints
and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement as are delegated to the Administrative
Agent and the Collateral Agent, respectively, by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance
with their terms all the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

(d) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall
maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance
delivered to it and a register for the recordation of the names and addresses of the Lenders, and
the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and
Parent, the Borrowers, the Administrative Agent, the Issuing Bank, the Collateral Agent and the
Lenders may treat each person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.
The Register shall be available for inspection by Parent, the Borrowers, the Issuing Bank, the
Collateral Agent and any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

(e) Upon its receipt of, and consent to, a duly completed Assignment and Acceptance executed
by an assigning Lender and an assignee, an Administrative Questionnaire completed in respect of the
assignee (unless the assignee shall already be a Lender hereunder), the processing and recordation
fee referred to in paragraph (b) of this Section, if applicable, and, if required, the written
consent of Parent, the Swingline Lender and the Issuing Bank to such assignment and any applicable
tax forms, the Administrative Agent shall (i) accept such Assignment and Acceptance and (ii) record
the information contained therein in the Register. No assignment shall be effective unless it has
been recorded in the Register as provided in this paragraph.

(f) Each Lender may without the consent of Parent, any Borrower, the Swingline Lender, the
Issuing Bank or the Administrative Agent sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement (including all or a portion
of its Commitment and the Loans owing to it); provided, however, that (i) such Lender’s obligations
under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to
the other parties hereto for the performance of such obligations, (iii) the participating banks or
other entities shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.14, 2.16 and 2.20 to the same extent as if they were Lenders (but, with respect to any
particular participant, to no greater extent than the Lender that sold the participation to such
participant) and (iv) Parent, the Borrowers, the Administrative Agent, the Collateral Agent, the
Issuing Bank and the Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement, and such Lender shall
retain the sole right to enforce the obligations of the Borrowers relating to the Loans or L/C
Disbursements and to approve any amendment, modification or waiver of any provision of this
Agreement (other than amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the Loans, extending any
scheduled principal payment date or date fixed for the payment of interest on the Loans, increasing
or extending the Commitments or releasing any Guarantor or all or any substantial part of the
Collateral).

(g) Any Lender or participant may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section, disclose to the assignee or
participant or proposed assignee or participant any information relating to Parent and the
Borrowers furnished to such Lender by or on behalf of Parent or the Borrowers; provided that, prior
to any such disclosure of information designated by Parent or any Borrower as confidential, each
such assignee or participant or proposed assignee or participant shall execute an agreement whereby
such assignee or participant shall agree (subject to customary exceptions) to preserve the
confidentiality of such confidential information on terms no less restrictive than those applicable
to the Lenders pursuant to Section 9.16.

(h) Any Lender may at any time assign all or any portion of its rights under this Agreement to
secure extensions of credit to such Lender or in support of obligations owed by such Lender;
provided that no such assignment shall release a Lender from any of its obligations hereunder or
substitute any such assignee for such Lender as a party hereto.

(i) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting
Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender,
identified as such in writing from time to time by the Granting Lender to the Administrative Agent
and Parent, the option to provide to any Borrower all or any part of any Loan that such Granting
Lender would otherwise be obligated to make to any Borrower pursuant to this Agreement; provided
that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an
SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan,
the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making
of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees
that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement
(all liability for which shall remain with the Granting Lender). In furtherance of the foregoing,
each party hereto hereby agrees (which agreement shall survive the termination of this Agreement)
that, prior to the date that is one year and one day after the payment in full of all outstanding
commercial paper or other senior indebtedness of any SPC, it will not institute against, or join
any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings under the laws of the United States of America or any State
thereof. In addition, notwithstanding anything to the contrary contained in this Section, any SPC
may (i) with notice to, but without the prior written consent of, Parent and the Administrative
Agent and without paying any processing fee therefor, assign all or a portion of its interests in
any Loans to the Granting Lender or to any financial institutions (consented to by Parent and
Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC
to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any
non-public information relating to its Loans to any rating agency, commercial paper dealer or
provider of any surety, guarantee or credit or liquidity enhancement to such SPC.

(j) Neither Parent nor any Borrower shall assign or delegate any of its rights or duties
hereunder without the prior written consent of the Administrative Agent, the Issuing Bank and each
Lender, and any attempted assignment without such consent shall be null and void.

(k) In the event that S&P, Moody’s and Thompson’s BankWatch (or InsuranceWatch Ratings
Service, in the case of Lenders that are insurance companies (or Best’s Insurance Reports, if such
insurance company is not rated by Insurance Watch Ratings Service)) shall, after the date that any
Lender becomes a Revolving Credit Lender, downgrade the long-term certificate deposit ratings of
such Lender, and the resulting ratings shall be below BBB-, Baa3 and C (or BB, in the case of a
Lender that is an insurance company (or B, in the case of an insurance company not rated by
InsuranceWatch Ratings Service)), then the Issuing Bank shall have the right, but not the
obligation, at its own expense, upon notice to such Lender and the Administrative Agent, to replace
(or to request Parent and the Borrowers to use their reasonable efforts to replace) such Lender
with an assignee (in accordance with and subject to the restrictions contained in paragraph (b) of
this Section), and such Lender hereby agrees to transfer and assign without recourse (in accordance
with and subject to the restrictions contained in paragraph (b) of this Section) all its interests,
rights and obligations in respect of its Revolving Credit Commitment to such assignee; provided,
however, that (i) no such assignment shall conflict with any law, rule and regulation or order of
any Governmental Authority and (ii) the Issuing Bank or such assignee, as the case may be, shall
pay to such Lender in immediately available funds on the date of such assignment the principal of
and interest accrued to the date of payment on the Loans made by such Lender hereunder and all
other amounts accrued for such Lender’s account or owed to it hereunder.

SECTION 9.05. Expenses; Indemnity. (a) The Borrowers and Parent agree, jointly and
severally, to pay all reasonable out-of-pocket expenses incurred by the Administrative Agent, the
Collateral Agent, the Issuing Bank, the Swingline Lender and the Arrangers in connection with the
syndication of the credit facilities provided for herein and the preparation and administration of
this Agreement and the other Loan Documents or in connection with any amendments, modifications or
waivers of the provisions hereof or thereof (whether or not the transactions hereby or thereby
contemplated shall be consummated) or incurred by the Administrative Agent, the Collateral Agent,
any Lender or any Arranger in connection with the enforcement or protection of its rights in
connection with this Agreement and the other Loan Documents or in connection with the Loans made or
Letters of Credit issued hereunder, including the reasonable fees, charges and disbursements of
Cravath, Swaine & Moore LLP and Moore & Van Allen, PLLC, counsel for the Administrative Agent, the
Collateral Agent and the Arrangers, and, in connection with any such enforcement or protection, the
reasonable fees, charges and disbursements of any other counsel for the Administrative Agent, the
Collateral Agent or any Lender.

(b) The Borrowers and Parent agree, jointly and severally, to indemnify the Administrative
Agent, the Collateral Agent, each Lender, the Issuing Bank, each Arranger and each Related Party of
any of the foregoing persons (each such person being called an “Indemnitee”) against, and to hold
each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related
expenses, including reasonable counsel fees, charges and disbursements, incurred by or asserted
against any Indemnitee arising out of, in any way connected with, or as a result of (i) the
execution or delivery of this Agreement or any other Loan Document or any agreement or instrument
contemplated thereby, the performance by the parties thereto of their respective obligations
thereunder or the consummation of the Credit Transactions and the other transactions contemplated
thereby, (ii) the use of the proceeds of the Loans or issuance of Letters of Credit, (iii) any
claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any
Indemnitee is a party thereto, or (iv) any actual or alleged presence or Release of Hazardous
Materials on any property currently or formerly owned or operated by Parent or any Subsidiary, or
any Environmental Liability related in any way to Parent or any Subsidiary; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the gross negligence or willful misconduct
of such Indemnitee.

(c) To the extent that Parent and the Borrowers fail to pay any amount required to be paid by
them to the Administrative Agent, the Collateral Agent, the Issuing Bank or the Swingline Lender
under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the
Administrative Agent, the Collateral Agent, the Issuing Bank or the Swingline Lender, as the case
may be, such Lender’s pro rata share (determined, in the manner provided below, as of the time that
the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided
that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as
the case may be, was incurred by or asserted against the Administrative Agent, the Collateral
Agent, the Issuing Bank or the Swingline Lender in its capacity as such. For purposes hereof, a
Lender’s “pro rata share” shall be determined based upon its share of the sum of the Aggregate
Revolving Credit Exposure, outstanding Term Loans and unused Commitments at the time.

(d) To the extent permitted by applicable law, neither Parent nor any Borrower shall assert,
and each 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) The provisions of this Section shall remain operative and in full force and effect
regardless of the expiration of the term of this Agreement, the consummation of the transactions
contemplated hereby, the repayment of any of the Loans, the expiration of the Commitments, the
expiration of any Letter of Credit, the invalidity or unenforceability of any term or provision of
this Agreement or any other Loan Document, or any investigation made by or on behalf of the
Administrative Agent, the Collateral Agent, any Lender or the Issuing Bank. All amounts due under
this Section shall be payable on written demand therefor.

SECTION 9.06. Right of Setoff. If an Event of Default shall have occurred and be continuing,
each Lender is hereby authorized at any time and from time to time, except to the extent prohibited
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 indebtedness at any time owing by such Lender to or for the
credit or the account of any Borrower or Parent against any of and all the obligations of any
Borrower or Parent now or hereafter existing under this Agreement and other Loan Documents held by
such Lender, irrespective of whether or not such Lender shall have made any demand under this
Agreement or such other Loan Document and although such obligations may be unmatured. The rights
of each Lender under this Section are in addition to other rights and remedies (including other
rights of setoff) which such Lender may have.

SECTION 9.07. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN LETTERS
OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH
AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. EACH LETTER OF CREDIT SHALL BE GOVERNED BY, AND
SHALL BE CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN SUCH LETTER OF CREDIT, OR IF
NO SUCH LAWS OR RULES ARE DESIGNATED, THE UNIFORM CUSTOMS AND PRACTICE FOR DOCUMENTARY CREDITS MOST
RECENTLY PUBLISHED AND IN EFFECT, ON THE DATE SUCH LETTER OF CREDIT WAS ISSUED, BY THE
INTERNATIONAL CHAMBER OF COMMERCE (THE “UNIFORM CUSTOMS”) AND, AS TO MATTERS NOT GOVERNED BY THE
UNIFORM CUSTOMS, THE LAWS OF THE STATE OF NEW YORK.

SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the Administrative Agent, the
Collateral Agent, any Lender or the Issuing Bank in exercising any power or right hereunder or
under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such
a right or power, preclude any other or further exercise thereof or the exercise of any other right
or power. The rights and remedies of the Administrative Agent, the Collateral Agent, the Issuing
Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of
this Agreement or any other Loan Document or consent to any departure by any Borrower or any other
Loan Party therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice or demand on any Borrower or
Parent in any case shall entitle any Borrower or Parent to any other or further notice or demand in
similar or other circumstances.

(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 Borrowers, Parent and the
Required Lenders; provided, however, that no such agreement shall (i) decrease the principal amount
of, or extend the maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan or any date for reimbursement of an L/C Disbursement, or waive or excuse
any such payment or any part thereof, or decrease the rate of interest on any Loan or L/C
Disbursement, without the prior written consent of each Lender affected thereby, (ii) increase or
extend the Commitment or decrease or extend the date for payment of any Fees of any Lender without
the prior written consent of such Lender, (iii) amend or modify the pro rata requirements of
Section 2.17, the provisions of Section 9.04(j) or the provisions of this Section or release any
Guarantor (except as expressly provided in Section 9.17) or all or any substantial part of the
Collateral, without the prior written consent of each Lender, (iv) change the provisions of any
Loan Document in a manner that by its terms adversely affects the rights in respect of payments due
to Lenders holding Loans of one Class differently from the rights of Lenders holding Loans of any
other Class without the prior written consent of Lenders holding a majority in interest of the
outstanding Loans and unused Commitments of each adversely affected Class, (v) modify the
protections afforded to an SPC pursuant to the provisions of Section 9.04(i) without the written
consent of such SPC or (vi) reduce the percentage contained in the definition of the term “Required
Lenders” without the prior written consent of each Lender (it being understood that with the
consent of the Required Lenders, additional extensions of credit pursuant to this Agreement may be
included in the determination of the Required Lenders on substantially the same basis as the Term
Loan Commitments and Revolving Credit Commitments on the date hereof); provided further that no
such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative
Agent, the Collateral Agent, the Issuing Bank or the Swingline Lender hereunder or under any other
Loan Document without the prior written consent of the Administrative Agent, the Collateral Agent,
the Issuing Bank or the Swingline Lender, respectively. Notwithstanding the foregoing, if the
terms of any amendment to this Agreement provide that any Class of Loans will be repaid in full and
the Commitments of such Class (if any) terminated as a condition to the effectiveness of such
amendment, then so long as the Loans and Commitments (if any) of such Class are in fact repaid and
terminated upon the effectiveness of such amendment, such Loans and Commitments shall not be
included in the determination of the Required Lenders with respect to such amendment.

SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if
at any time the interest rate applicable to any Loan or participation in any L/C Disbursement,
together with all fees, charges and other amounts which are treated as interest on such Loan or
participation in such L/C Disbursement 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 or participation in accordance with applicable
law, the rate of interest payable in respect of such Loan or participation 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 or
participation 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 participations 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.

SECTION 9.10. Entire Agreement. This Agreement, the other Loan Documents, the Fee Letter and
the Rollover Agreement constitute the entire contract between the parties relative to the subject
matter hereof. Any other previous agreement among the parties with respect to the subject matter
hereof is superseded by this Agreement and the other Loan Documents. Nothing in this Agreement or
in the other Loan Documents, expressed or implied, is intended to confer upon any person (other
than the parties hereto and thereto, their respective successors and assigns permitted hereunder
(including any Affiliate of the Issuing Bank that issues any Letter of Credit) and, to the extent
expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the
Collateral Agent, the Issuing Bank and the Lenders) any rights, remedies, obligations or
liabilities under or by reason of this Agreement or the other Loan Documents.

SECTION 9.11. 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 RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE
OTHER LOAN DOCUMENTS. 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,
AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 9.12. Severability. In the event any one or more of the provisions contained in this
Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions contained herein and
therein shall not in any way be affected or impaired thereby (it being understood that the
invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect
the validity of such provision in any other jurisdiction). The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to that of the invalid, illegal
or unenforceable provisions.

SECTION 9.13. Counterparts. 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, and shall become effective as
provided in Section 9.03. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart of this Agreement.

SECTION 9.14. 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 are not to affect the
construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) Each of Parent and the
Borrowers hereby irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or Federal court of the United States of
America sitting in New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement or the other Loan Documents, 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 Collateral Agent, the Issuing Bank or any Lender may otherwise have to bring any action
or proceeding relating to this Agreement or the other Loan Documents against any Borrower, Parent
or their respective properties in the courts of any jurisdiction.

(b) Each of Parent and the Borrowers hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may now or hereafter
have to the laying of venue of any suit, action or proceeding arising out of or relating to this
Agreement or the other Loan Documents in any New York State or Federal court. Each of the parties
hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such court.

(c) Each party to this Agreement irrevocably consents to service of process in the manner
provided for notices in Section 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 9.16. Confidentiality. Each of the Administrative Agent, the Collateral Agent, the
Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates’ officers,
directors, employees and agents, including accountants, legal counsel and other advisors (it being
understood that the persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information confidential), (b) to the extent
requested by any regulatory authority or quasi-regulatory authority (such as the National
Association of Insurance Commissioners), (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) in connection with the exercise of any
remedies hereunder or under the other Loan Documents or any suit, action or proceeding relating to
the enforcement of its rights hereunder or thereunder, (e) subject to an agreement containing
provisions substantially the same as those of this Section, to (i) any actual or prospective
assignee of or participant in any of its rights or obligations under this Agreement and the other
Loan Documents or (ii) any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to Parent or any Subsidiary or any of their respective obligations,
(f) with the consent of Parent or (g) to the extent such Information becomes publicly available
other than as a result of a breach of this Section. For the purposes of this Section,
“Information” shall mean all information received from any Borrower or Parent and related to any
Borrower or Parent or their business, other than any such information that was available to the
Administrative Agent, the Collateral Agent, the Issuing Bank or any Lender on a nonconfidential
basis prior to its disclosure by any Borrower or Parent; provided that, in the case of Information
received from any Borrower or Parent after the date hereof, such information is clearly identified
at the time of delivery as confidential. Information also includes all protected health
information (“PHI”), as such term is defined in 45 C.F.R. 164.501, including information that
concerns an individual’s past, present or future physical or mental health or condition, the
provision of care to the individual, or the past, present or future payment for such care, and that
directly or indirectly identifies an individual or that could reasonably be used to identify an
individual. Any person required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its obligation to do so if such person has
exercised the same degree of care to maintain the confidentiality of such Information as such
person would accord its own confidential information. Without limiting the generality of the
foregoing, each Lender will (i) treat all PHI as confidential, (ii) not disseminate, disclose or
otherwise use PHI in a manner inconsistent with the Health Insurance Portability and Accountability
Act Privacy Regulations codified at 45 C.F.R. 160 et seq. (the “HIPAA Privacy Standards”), (iii) to
the extent required by the HIPAA Privacy Standards, make PHI available to Parent and/or an
