Exhibit 10.2

GUARANTEE

     FOR VALUE RECEIVED, the sufficiency of which is hereby acknowledged, and in connection with
that certain funding agreement (the “Funding Agreement”), entered into by and between Principal
Life Insurance Company, an Iowa insurance company (“Principal Life”), and Principal Life Income
Fundings Trust 31, a New York common law trust (the “Trust”), relating to the notes (the “Notes”)
issued by the Trust, Principal Financial Group, Inc., a Delaware corporation and the indirect
parent company of Principal Life (the “Guarantor”), hereby furnishes to the Trust its full and
unconditional guarantee of the Guaranteed Amounts (as hereinafter defined) as follows:

     1. Guarantee.

               (a) The Guarantor hereby fully, irrevocably, absolutely and unconditionally guarantees, as a
guarantee of payment and not merely as a guarantee of collection, immediate payment when due to the
Trust any payments required to be made by Principal Life to the Trust under the Funding Agreement
which shall become due and payable regardless of whether such payment is due at maturity, on an
interest payment date or as a result of redemption or otherwise (the “Scheduled Payments”) but
shall be unpaid by Principal Life (the “Guaranteed Amounts”). Notwithstanding anything to the
contrary contained herein, in no event shall the Guaranteed Amounts exceed the Deposit (as defined
in the Funding Agreement) of the Funding Agreement, plus accrued but unpaid interest and any other
amounts due and owing under the Funding Agreement, less any amounts paid by Principal Life to the
Trust.

               (b) In the event that Principal Life fails to make a Scheduled Payment in full when due (the
“Payment Notice Date”), then the Trust or Citibank, N.A., as indenture trustee for the benefit of
the holders of the Notes (the “Indenture Trustee”), pursuant to the indenture (the “Indenture”)
between the Trust and the Indenture Trustee, may present the Guarantor with notice (each, a
“Payment Notice”) of such failure in writing on or after the Payment Notice Date. The Payment
Notice shall identify (1) the Funding Agreement, (2) the Trust, (3) the Payment Notice Date and (4)
the amount of the Scheduled Payments not paid by Principal Life to the Trust as of the Payment
Notice Date. Upon receipt of such Payment Notice, the Guarantor will immediately pay the
Guaranteed Amounts pursuant to Section 7.

               (c) In the event that, after receipt of a Payment Notice from the Trust, the Guarantor fails
to make immediate payment to the Trust or the Indenture Trustee of the Guaranteed Amounts, then
the Trust and the Indenture Trustee may enforce the obligations of the Guarantor under this
Guarantee, including by immediately bringing suit directly against the Guarantor (without first
bringing suit against Principal Life) for the Guaranteed Amounts not paid to the Trust as of the
Payment Notice Date.

               (d) This Guarantee is an unsecured, unsubordinated and contingent obligation of the Guarantor
and ranks equally with all other unsecured and unsubordinated obligations of the Guarantor.

1

 

               2. Termination. This Guarantee is a continuing and irrevocable guarantee of the
Guaranteed Amounts now or hereafter existing and shall terminate and be of no further force and
effect with respect to the Funding Agreement and the Notes upon the full payment of the Scheduled
Payments or upon the earlier extinguishment of the obligations of Principal Life under the Funding
Agreement.

               3. Amendments. Subject to the trust agreement relating to the Trust and the Indenture, no
provision of this Guarantee may be waived, amended, supplemented or modified, except by a written
instrument executed by the Trust and the Guarantor.

               4. Assignment; Governing Law. This Guarantee shall inure to the benefit of the Trust and its
successors, assigns and pledgees. This Guarantee shall be governed by, and construed in accordance
with, the laws of the State of New York without regard to conflict of law principles.

               5. Notices. All notices given pursuant to this Guarantee shall be in writing, and shall
either be delivered, mailed or telecopied to the locations listed below or at such other address or
to the attention of such other persons as such party shall have designated for such purpose in a
written notice complying as to delivery with the terms of this Section 5. Each such notice shall
be effective (i) if given by telecopy, when transmitted to the applicable number so specified in
this Section 5 (such notice shall also be sent by mail, with first class postage prepaid), (ii) if
given by mail, three days after deposit in the mails with first class postage prepaid, or (iii) if
given by any other means, when actually delivered at such address.

ARTICLE II

AMOUNTS AND TERMS OF THE ADVANCES AND LETTERS OF CREDIT

     SECTION 2.01. The Advances and Letters of Credit. (a) Advances. Each Lender
severally agrees, on the terms and conditions hereinafter set forth, to make Advances to the
Borrower from time to time on any Business Day during the period from the Effective Date until the
Termination Date in an amount not to exceed at any time such Lender’s Unused Revolving Credit
Commitment. Each Borrowing shall be in an aggregate amount of $10,000,000 or an integral multiple
of $1,000,000 in excess thereof and shall consist of Advances of the same Type made on the same day
by the Lenders ratably according to their respective Revolving Credit Commitments. Within the
limits of each Lender’s Revolving Credit Commitment, the Borrower may borrow under this Section
2.01(a), prepay pursuant to Section 2.10 and reborrow under this Section 2.01(a).

     (b) Letters of Credit. Each Issuing Bank agrees, on the terms and
conditions hereinafter set forth, to issue letters of credit (each, a “Letter of Credit”)
for the account of the Borrower from time to time on any Business Day during the period from the
Effective Date until 30 days before the Termination Date in an aggregate Available Amount (i) for
all Letters of Credit issued by each Issuing Bank not to exceed at any time the lesser of (x) the
Letter of Credit Facility at such time and (y) such Issuing Bank’s Letter of Credit Commitment at
such time and (ii) for each such Letter of Credit not to exceed an amount equal to the aggregate
Unused Revolving Credit Commitments of the Lenders at such time. Each Letter of Credit shall be
for an amount of $50,000 or more. No Letter of Credit shall have an expiration date (including all
rights of the Borrower or the beneficiary to require renewal) later than the earlier of (x) the
date that is one year after the date of issuance thereof; provided that any Letter of
Credit which provides for automatic one-year extension(s) of such expiration date shall be deemed
to comply with the foregoing requirement if the Issuing Bank has the unconditional right to prevent
any such automatic extension from taking place or (y) five Business Days prior to the Termination
Date. Within the limits referred to above, the Borrower may request the issuance of Letters of
Credit under this Section 2.01(b), repay any Advances resulting from drawings thereunder pursuant
to Section 2.03(c) and request the issuance of additional Letters of Credit under this Section
2.01(b). Each letter of credit listed on Schedule 2.01(b) shall be deemed to constitute a Letter
of Credit issued hereunder, and each Lender or each Affiliate of a Lender that is an issuer of such
a Letter of Credit shall, for purposes of Section 2.03, be deemed to be an Issuing Bank for each
such letter of credit, provided than any renewal or replacement of any such letter of
credit shall be issued by an Issuing Bank pursuant to the terms of this Agreement.

     SECTION 2.02. Making the Advances. (a) Except as otherwise provided in Section
2.03(c), each Borrowing shall be made on notice, given not later than (x) 12:00 Noon (New York City
time) on the third Business Day prior to the date of the proposed Borrowing in the case of a
Borrowing consisting of Eurodollar Rate Advances or (y) 10:00 A.M. (New York

16

 

City time) on the date of the proposed Borrowing in the case of a Borrowing consisting of Base
Rate Advances, by the Borrower to the Agent, which shall give each Lender prompt notice thereof by
telecopier. Each such notice of a Borrowing (a “Notice of Borrowing”) shall be by
telephone, confirmed immediately in writing or by telecopier in substantially the form of Exhibit B
hereto, specifying therein the requested (i) date of such Borrowing, (ii) Type of Advances
comprising such Borrowing, (iii) aggregate amount of such Borrowing, and (iv) in the case of a
Borrowing consisting of Eurodollar Rate Advances, initial Interest Period for each such Advance.
Each Lender shall, before 12:00 Noon (New York City time) on the date of such Borrowing, make
available for the account of its Applicable Lending Office to the Agent at the Agent’s Account, in
same day funds, such Lender’s ratable portion of such Borrowing. After the Agent’s receipt of such
funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will
make such funds available to the Borrower at the Agent’s address referred to in Section 8.02.

          (b) Anything in subsection (a) above to the contrary notwithstanding, (i) the Borrower may not
select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less
than $10,000,000 or if the obligation of the Lenders to make Eurodollar Rate Advances shall then be
suspended pursuant to Section 2.08 or 2.12 and (ii) the Eurodollar Rate Advances may not be
outstanding as part of more than seven separate Borrowings.

          (c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of
any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate
Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by
such Lender as a result of any failure to fulfill on or before the date specified in such Notice of
Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without
limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the
Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such
failure, is not made on such date.

          (d) Unless the Agent shall have received notice from a Lender prior to the time of any
Borrowing under a Facility under which such Lender has a Commitment that such Lender will not make
available to the Agent such Lender’s ratable portion of such Borrowing, the Agent may assume that
such Lender has made such portion available to the Agent on the date of such Borrowing in
accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount. If and to the
extent that such Lender shall not have so made such portion available to the Agent, such Lender and
the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made available to the
Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the
interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of
such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding
amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for
purposes of this Agreement.

17

 

          (e) The failure of any Lender to make the Advance to be made by it as part of any Borrowing
shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the
date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to
make the Advance to be made by such other Lender on the date of any Borrowing.

          SECTION 2.03. Issuance of and Drawings and Reimbursement Under Letters of Credit. (a)
Request for Issuance. (i) Each Letter of Credit shall be issued upon notice, given not
later than 1:00 P.M. (New York City time) on the fifth Business Day prior to the date of the
proposed issuance of such Letter of Credit (or on such shorter notice as the applicable Issuing
Bank may agree), by the Borrower to any Issuing Bank, and such Issuing Bank shall give the Agent
prompt notice thereof by telecopier. Each such notice of issuance of a Letter of Credit (a
“Notice of Issuance”) shall be by telephone, confirmed immediately in writing or by
telecopier, specifying therein the requested (A) date of such issuance (which shall be a Business
Day), (B) Available Amount of such Letter of Credit, (C) expiration date of such Letter of Credit
(which shall not be later than the earlier of the Termination Date or one year after the date of
issuance thereof; provided that any Letter of Credit which provides for automatic one-year
extension(s) of such expiration date shall be deemed to comply with the foregoing requirement if
the Issuing Bank has the unconditional right to prevent any such automatic extension from taking
place, and each Issuing Bank hereby agrees to exercise such right to the extent necessary to
prevent any such Letter of Credit from being outstanding after the Termination Date), (D) name and
address of the beneficiary of such Letter of Credit and (E) form of such Letter of Credit, and
shall be accompanied by such customary application and agreement for letter of credit as such
Issuing Bank may specify to the Borrower for use in connection with such requested Letter of Credit
(a “Letter of Credit Agreement”). If the requested form of such Letter of Credit is
acceptable to such Issuing Bank in its sole discretion, such Issuing Bank will, upon fulfillment of
the applicable conditions set forth in Article III, make such Letter of Credit available to the
Borrower at its office referred to in Section 8.02 or as otherwise agreed with the Borrower in
connection with such issuance. In the event and to the extent that the provisions of any Letter of
Credit Agreement shall conflict with this Agreement, the provisions of this Agreement shall govern.

          (b) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the
applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each
Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to
such Lender’s Ratable Share of the aggregate amount available to be drawn under such Letter of
Credit. The Borrower hereby agrees to each such participation. Each 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 any amendment, renewal or extension of any Letter of Credit or the occurrence
and continuance of a Default or reduction or termination of the Revolving Credit Commitments, and
that each such payment shall be made without any offset, abatement, withholding or reduction
whatsoever. Each Lender further acknowledges and agrees that its participation in each Letter of
Credit will be automatically adjusted to reflect such Lender’s Ratable Share of the Available
Amount of such Letter of Credit at each time such

18

 

Lender’s Revolving Credit Commitment is amended pursuant to the operation of Section 2.18, by
an assignment in accordance with Section 8.07 or otherwise pursuant to this Agreement.

          (c) Drawing and Reimbursement. The payment by an Issuing Bank of a draft drawn under
any Letter of Credit shall constitute for all purposes of this Agreement the making by such Issuing
Bank of an Advance, which shall be a Base Rate Advance, in the amount of such draft. Each Issuing
Bank shall give prompt notice (and such Issuing Bank will use its commercially reasonable efforts
to deliver such notice within one Business Day) to the Borrower and the Agent of each drawing under
any Letter of Credit issued by it. Upon written demand by such Issuing Bank, with a copy of such
demand to the Agent, each Lender shall pay to the Agent such Lender’s Ratable Share of such
outstanding Advance, by making available for the account of its Applicable Lending Office to the
Agent for the account of such Issuing Bank, by deposit to the Agent’s Account, in same day funds,
an amount equal to the portion of the outstanding principal amount of such Advance to be funded by
such Lender. Promptly after receipt thereof, the Agent shall transfer such funds to such Issuing
Bank. Each Lender agrees to fund its Ratable Share of such outstanding Advance on (i) the Business
Day on which demand therefor is made by such Issuing Bank, provided that notice of such
demand is given not later than 11:00 A.M. (New York City time) on such Business Day, or (ii) the
first Business Day next succeeding such demand if notice of such demand is given after such time.
If and to the extent that any Lender shall not have so made the amount of such Advance available to
the Agent, such Lender agrees to pay to the Agent forthwith on demand such amount together with
interest thereon, for each day from the date of demand by any such Issuing Bank until the date such
amount is paid to the Agent, at the Federal Funds Rate for its account or the account of such
Issuing Bank, as applicable. If such Lender shall pay to the Agent such amount for the account of
any such Issuing Bank on any Business Day, such amount so paid in respect of principal shall
constitute an Advance made by such Lender on such Business Day for purposes of this Agreement, and
the outstanding principal amount of the Advance made by such Issuing Bank shall be reduced by such
amount on such Business Day.

          (d) Letter of Credit Reports. Each Issuing Bank shall furnish (i) to the Agent on the
first Business Day of each month a written report summarizing issuance and expiration dates of
Letters of Credit issued by it during the preceding month and drawings during such month under all
Letters of Credit and (ii) to the Agent and each Lender on the first Business Day of each calendar
quarter a written report setting forth the average daily aggregate Available Amount during the
preceding calendar quarter of all Letters of Credit issued by it.

          (e) Failure to Make Advances. The failure of any Lender to make the Advance to be
made by it on the date specified in Section 2.03(c) shall not relieve any other Lender of its
obligation hereunder to make its Advance on such date, but no Lender shall be responsible for the
failure of any other Lender to make the Advance to be made by such other Lender on such date.

          SECTION 2.04. Fees. (a) Commitment Fee. The Borrower agrees to pay to the
Agent for the account of each Lender a commitment fee on the average daily amount of such Lender’s
Unused Revolving Credit Commitment from the date hereof in the case of each Initial Lender and from
the effective date specified in the Assumption Agreement or in the Assignment and Acceptance
pursuant to which it became a Lender in the case of each other Lender until the

19

 

Termination Date at a rate per annum equal to the Applicable Percentage in effect from time to
time, payable in arrears quarterly on the last day of each March, June, September and December,
commencing September 30, 2007, and on the Termination Date.

          (b) Letter of Credit Fees. (i) The Borrower shall pay to the Agent for the account
of each Lender a commission on such Lender’s Ratable Share of the average daily aggregate Available
Amount of all Letters of Credit outstanding from time to time at a rate per annum equal to the
Applicable Margin for Eurodollar Rate Advances in effect from time to time, payable in arrears
quarterly on the last day of each March, June, September and December, commencing September 30,
2007, and on the Termination Date, and after the Termination Date payable upon demand;
provided that the Applicable Margin shall increase by 2% upon the occurrence and during the
continuation of an Event of Default if the Borrower is required to pay default interest pursuant to
Section 2.07(b).

     (ii) The Borrower shall pay to each Issuing Bank for its own account such reasonable and
customary fronting, issuance, presentation, amendment and other processing fees as may from
time to time be agreed in writing between the Borrower and such Issuing Bank.

as have been agreed between the Borrower and the Agent.

shall have the right, upon at least three Business Days’ notice to the Agent, to terminate in whole
or permanently reduce ratably in part the Unused Revolving Credit Commitments or the Unissued
Letter of Credit Commitments, provided that each partial reduction of a Facility (i) shall
be in the aggregate amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof
and (ii) with respect to the Revolving Credit Facility, shall be made ratably among the Lenders in
accordance with their Commitments.

          SECTION 2.06. Repayment. (a) Advances. The Borrower shall repay to the
Agent for the ratable account of the Lenders on the Termination Date the aggregate principal amount
of the Advances then outstanding.

          (b) Letter of Credit Reimbursements. The obligations of the Borrower under this
Agreement, any Letter of Credit Agreement and any other agreement or instrument relating to any
Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance
with the terms of this Agreement, such Letter of Credit Agreement and such other agreement or
instrument under all circumstances, including, without limitation, the following circumstances (it
being understood that any such payment by the Borrower is without prejudice to, and does not
constitute a waiver of, any rights the Borrower might have or might acquire as a result of the
payment by any Lender of any draft or the reimbursement by the Borrower thereof):

     (i) any lack of validity or enforceability of this Agreement, any Letter of Credit, any
Letter of Credit Agreement or any other agreement or instrument, in each case, relating
thereto (all of the foregoing being, collectively, the “L/C Related Documents”);

20

 

     (ii) any change in the time, manner or place of payment of, or in any other term of,
all or any of the obligations of the Borrower in respect of any L/C Related Document or any

Documents;

     (iii) the existence of any claim, set-off, defense or other right that the Borrower may
have at any time against any beneficiary or any transferee of a Letter of Credit (or any
Persons for which any such beneficiary or any such transferee may be acting), any Issuing
Bank, the Agent, any Lender or any other Person, whether in connection with the transactions
contemplated by the L/C Related Documents or any unrelated transaction;

     (iv) any statement or any 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 any Issuing Bank under a Letter of Credit against presentation of a
draft or certificate that does not strictly comply with the terms of such Letter of Credit;

     (vi) any exchange, release or non-perfection of any collateral, or any release or
amendment or waiver of or consent to departure from any guarantee, for all or any of the
obligations of the Borrower in respect of the L/C Related Documents; or

     (vii) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, including, without limitation, any other circumstance that might otherwise
constitute a defense available to, or a discharge of, the Borrower or a guarantor.

          SECTION 2.07. Interest on Advances. (a) Scheduled Interest. The Borrower
shall pay interest on the unpaid principal amount of each Advance owing to each Lender from the
date of such Advance until such principal amount shall be paid in full, at the following rates per

day of such Interest Period and, if such Interest Period has a duration of more than three
months, on each day that occurs during such Interest Period every three months from the
first day of such Interest Period and on the date such Eurodollar Rate Advance shall be
Converted or paid in full.

21

 

          (b) Default Interest. Upon the occurrence and during the continuance of an Event of
Default, the Agent may, and upon the request of the Required Lenders shall, require the Borrower to
pay interest (“Default Interest”) on (i) the unpaid principal amount of each Advance owing
to each Lender, payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above, at a
rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on
such Advance pursuant to clause (a)(i) or (a)(ii) above, as applicable, and (ii) to the fullest
extent permitted by law, the amount of any interest, fee or other amount payable hereunder that is
not paid when due, from the date such amount shall be due until such amount shall be paid in full,
payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum

Advances pursuant to clause (a)(i) above, provided, however, that following
acceleration of the maturity of the Advances pursuant to Section 6.01, Default Interest shall
accrue and be payable hereunder whether or not previously required by the Agent.

          SECTION 2.08. Interest Rate Determination. (a) Each Reference Bank agrees to furnish
to the Agent timely information for the purpose of determining each Eurodollar Rate. If any one or
more of the Reference Banks shall not furnish such timely information to the Agent for the purpose
of determining any such interest rate, the Agent shall determine such interest rate on the basis of
timely information furnished by the remaining Reference Banks. The Agent shall give prompt notice
to the Borrower and the Lenders of the applicable interest rate determined by the Agent for
purposes of Section 2.07(a)(i) or (ii), and the rate, if any, furnished by each Reference Bank for
the purpose of determining the interest rate under Section 2.07(a)(ii).

          (b) If, with respect to any Eurodollar Rate Advances under any Facility, the Lenders owed at
least 51% of the aggregate principal amount thereof notify the Agent that the Eurodollar Rate for
any Interest Period for such Advances will not adequately reflect the cost to such Required Lenders
of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest
Period, the Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each
Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period
therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to make, or to
Convert Advances into, Eurodollar Rate Advances shall be suspended and such Lenders have determined
that the circumstances causing such suspension no longer exist and the Agent shall so notify the
Borrower.

          (c) If the Borrower shall fail to select the duration of any Interest Period for any
Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest
Period” in Section 1.01, the Agent will forthwith so notify the Borrower and the Lenders and such
Advances will automatically, on the last day of the then existing Interest Period therefor, Convert
into Base Rate Advances.

          (d) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances
comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than
$10,000,000, such Advances shall automatically, on the last day of the then existing Interest
Period therefor, Convert into Base Rate Advances.

          (e) Upon the occurrence and during the continuance of any Event of Default, (i) each
Eurodollar Rate Advance will automatically, on the last day of the then existing Interest

22

 

Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to
make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended.

          (f) If Moneyline Telerate Markets Page 3750 is unavailable and fewer than two Reference Banks
furnish timely information to the Agent for determining the Eurodollar Rate for any Eurodollar Rate
Advances:

     (i) the Agent shall forthwith notify the Borrower and the Lenders that the interest
rate cannot be determined for such Eurodollar Rate Advances,

     (ii) each outstanding Eurodollar Rate Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance (or if such
Advance is then a Base Rate Advance, will continue as a Base Rate Advance), and

     (iii) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert
Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no longer exist.

          SECTION 2.09. Optional Conversion of Advances. The Borrower may on any Business Day,
upon notice given to the Agent not later than 12:00 Noon (New York City time) on the third Business
Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.08 and
2.12, Convert all or any portion of Advances of one Type comprising the same Borrowing into
Advances of the other Type; provided, however, that any Conversion of Eurodollar
Rate Advances into Base Rate Advances shall be made only on the last day of an Interest Period for
such Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate Advances
shall be in an amount not less than the minimum amount specified in Section 2.02(b), no Conversion
of any Advances shall result in more separate Borrowings than permitted under Section 2.02(b) and
each Conversion of Advances comprising part of the same Borrowing under any Facility shall be made
ratably among the Lenders in accordance with their Commitments under such Facility. Each such
notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such
Conversion, (ii) the Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate
Advances, the duration of the initial Interest Period for each such Advance. Each notice of
Conversion shall be irrevocable and binding on the Borrower.

          SECTION 2.10. Prepayments of Advances. The Borrower may, upon notice at least two
Business Days prior to the date of such prepayment, in the case of Eurodollar Rate Advances, and
not later than 12:00 Noon (New York City time) on the date of such prepayment, in the case of Base
Rate Advances, to the Agent stating the proposed date and aggregate principal amount of the
prepayment, and if such notice is given the Borrower shall prepay the outstanding principal amount
of the Advances comprising part of the same Borrowing in whole or ratably in part, together with
accrued interest to the date of such prepayment on the principal amount prepaid; provided,
however, that (x) each partial prepayment shall be in an aggregate principal amount of
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in the event of any
such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the
Lenders in respect thereof pursuant to Section 8.04(c).

23

 

          SECTION 2.11. Increased Costs. (a) If, due to either (i) the introduction of or any
change in or in the interpretation of any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other governmental authority (whether or not having
the force of law), there shall be any increase in the cost to any Lender of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances or agreeing to issue or of issuing or
maintaining or participating in Letters of Credit (excluding for purposes of this Section 2.11 any
such increased costs resulting from (i) Taxes or Other Taxes (as to which Section 2.14 shall
govern) and (ii) changes in the basis of taxation of overall net income or overall gross income by
the United States or by the foreign jurisdiction or state under the laws of which such Lender is
organized or has its Applicable Lending Office or any political subdivision thereof), then the
Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the
Agent), pay to the Agent for the account of such Lender additional amounts sufficient to compensate
such Lender for such increased cost; provided, however, that before making any such
demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to designate a different Applicable Lending Office if the making of
such a designation would avoid the need for, or reduce the amount of, such increased cost and would
not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. A
certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by
such Lender, shall be presumed correct for all purposes, absent manifest error.

          (b) If any Lender determines that compliance with any law or regulation or any guideline or
request from any central bank or other governmental authority (whether or not having the force of
law) affects or would affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such capital is increased
by or based upon the existence of such Lender’s commitment to lend or to issue or participate in
Letters of Credit hereunder and other commitments of this type or the issuance or maintenance of or
participation in the Letters of Credit (or similar contingent obligations), then, upon demand by
such Lender (with a copy of such demand to the Agent), the Borrower shall pay to the Agent for the
account of such Lender, from time to time as specified by such Lender, additional amounts
sufficient to compensate such Lender or such corporation in the light of such circumstances, to the
extent that such Lender reasonably determines such increase in capital to be allocable to the
existence of such Lender’s commitment to lend or to issue or participate in Letters of Credit
hereunder or the issuance or maintenance of or participation in the Letters of Credit. A
certificate as to such amounts submitted to the Borrower and the Agent by such Lender shall be
presumed correct for all purposes, absent manifest error.

          (c) Notwithstanding anything to the contrary in this Section 2.11, the Borrower shall not be
required to compensate a Lender pursuant to this Section for any amounts incurred more than ninety
days prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim
compensation therefor; provided that, if the circumstances giving rise to such claim have a
retroactive effect, then such ninety-day period shall be extended to include the period of such
retroactive effect. The obligations of the Borrower pursuant to this Section shall survive the
termination of this Agreement and the payment of the Advances and all other amounts payable
hereunder.

24

 

          SECTION 2.12. Illegality. Notwithstanding any other provision of this Agreement, if
any Lender shall notify the Agent that the introduction of or any change in or in the
interpretation of any law or regulation makes it unlawful, or any central bank or other
governmental authority asserts that it is unlawful, for any Lender or its Eurodollar Lending Office
to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain
Eurodollar Rate Advances hereunder, (a) each Eurodollar Rate Advance will automatically, upon such
demand, Convert into a Base Rate Advance and (b) the obligation of the Lenders to make Eurodollar
Rate Advances or to Convert Advances into Eurodollar Rate Advances shall be suspended until the
Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no
longer exist; provided, however, that before making any such demand, each Lender
agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different Eurodollar Lending Office if the making of such a
designation would allow such Lender or its Eurodollar Lending Office to continue to perform its
obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate
Advances and would not, in the judgment of such Lender, be otherwise disadvantageous to such
Lender.

          SECTION 2.13. Payments and Computations. (a) The Borrower shall make each payment
hereunder, irrespective of any right of counterclaim or set-off, not later than 11:00 A.M. (New
York City time) on the day when due in U.S. dollars to the Agent at the Agent’s Account in same day
funds. The Agent will promptly thereafter cause to be distributed like funds relating to the
payment of principal, interest, fees or commissions ratably (other than amounts payable pursuant to
Section 2.04(b)(ii), 2.11, 2.14 or 8.04(c)) to the Lenders for the account of their respective
Applicable Lending Offices, and like funds relating to the payment of any other amount payable to
any Lender to such Lender for the account of its Applicable Lending Office, in each case to be
applied in accordance with the terms of this Agreement. Upon any Assuming Lender becoming a Lender
hereunder as a result of a Commitment Increase pursuant to Section 2.18, and upon the Agent’s
receipt of such Lender’s Assumption Agreement and recording of the information contained therein in
the Register, from and after the applicable Increase Date, the Agent shall make all payments
hereunder and under any Notes issued in connection therewith in respect of the interest assumed
thereby to the Assuming Lender. Upon its acceptance of an Assignment and Acceptance and recording
of the information contained therein in the Register pursuant to Section 8.07(c), from and after
the effective date specified in such Assignment and Acceptance, the Agent shall make all payments
hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee
thereunder, and the parties to such Assignment and Acceptance shall make all appropriate
adjustments in such payments for periods prior to such effective date directly between themselves.

          (b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such
Lender is not made when due hereunder or under the Note held by such Lender, to charge from time to
time against any or all of the Borrower’s accounts with such Lender any amount so due.

          (c) All computations of interest based on the Base Rate shall be made by the Agent on the
basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on
the Eurodollar Rate or the Federal Funds Rate and of fees and Letter of Credit commissions shall be
made by the Agent on the basis of a year of 360 days, in each case for the

25

 

actual number of days (including the first day but excluding the last day) occurring in the
period for which such interest, fees or commissions are payable. Each determination by the Agent
of an interest rate hereunder shall be presumed correct for all purposes, absent manifest error.

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

          (e) Unless the Agent shall have received notice from the Borrower prior to the date on which
any payment is due to the Lenders hereunder that the Borrower will not make such payment in full,
the Agent may assume that the Borrower has made such payment in full to the Agent on such date and
the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due
date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall
not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith
on demand such amount distributed to such Lender together with interest thereon, for each day from
the date such amount is distributed to such Lender until the date such Lender repays such amount to
the Agent, at the Federal Funds Rate.

          SECTION 2.14. Taxes. (a) Any and all payments by the Borrower to or for the account
of any Lender or the Agent hereunder or under the Notes or any other documents to be delivered
hereunder shall be made, in accordance with Section 2.13 or the applicable provisions of such other
documents, free and clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each Lender and the Agent, taxes imposed on its overall net
income, and franchise taxes imposed on it in lieu of net income taxes, imposed on such Lender or
the Agent (as the case may be) as a result of a present or former connection between such Lender or
the Agent and the jurisdiction of the governmental authority imposing such tax or any political
subdivision thereof or taxing authority thereof or therein (other than any such connection arising
solely from such Lender or the Agent having executed, delivered or performed its obligations or
received a payment under, or enforced, this Agreement or any of the Notes) (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments
hereunder or under the Notes being hereinafter referred to as “Taxes”). If the Borrower
shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or
under any Note or any other documents to be delivered hereunder to any Lender or the Agent, (i) the
sum payable shall be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section 2.14) such Lender or
the Agent (as the case may be) receives an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower
shall pay the full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

          (b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or
any other excise or property taxes, charges or similar levies that arise from

26

 

any payment made hereunder or under the Notes or any other documents to be delivered hereunder
or from the execution, delivery or registration of, performing under, or otherwise with respect to,
this Agreement or the Notes or any other documents to be delivered hereunder (hereinafter referred
to as “Other Taxes”).

          (c) The Borrower shall indemnify each Lender and the Agent for and hold it harmless against
the full amount of Indemnified Taxes or Other Taxes (including, without limitation, taxes of any
kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.14) imposed on
or paid by such Lender or the Agent (as the case may be) and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. This indemnification shall be
made within 30 days from the date such Lender or the Agent (as the case may be) makes written
demand therefor.

          (d) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the
Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt
evidencing such payment to the extent such a receipt is issued therefor, or other written proof of
payment thereof that is reasonably satisfactory to the Agent. In the case of any payment hereunder
or under the Notes or any other documents to be delivered hereunder by or on behalf of the Borrower
through an account or branch outside the United States or by or on behalf of the Borrower by a
payor that is not a United States person, if the Borrower determines that no Taxes are payable in
respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Agent, at
such address, an opinion of counsel acceptable to the Agent stating that such payment is exempt
from Taxes. For purposes of this subsection (d) and subsection (e), the terms “United
States” and “United States person” shall have the meanings specified in Section 7701 of
the Internal Revenue Code.

          (e) Each Lender organized under the laws of a jurisdiction outside the United States, on or
prior to the date of its execution and delivery of this Agreement in the case of each Initial
Lender and on the date of the Assumption Agreement or the Assignment and Acceptance pursuant to
which it becomes a Lender in the case of each other Lender, and from time to time thereafter as
reasonably requested in writing by the Borrower (but only so long as such Lender remains lawfully
able to do so), shall provide each of the Agent and the Borrower with two original Internal Revenue
Service Forms W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the
Internal Revenue Service, certifying that such Lender is exempt from or entitled to a reduced rate
of United States withholding tax on payments pursuant to this Agreement or the Notes. If the form
provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a
United States interest withholding tax rate in excess of zero, withholding tax at such rate shall
be considered excluded from Taxes unless and until such Lender provides the appropriate forms
certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be
considered excluded from Taxes for periods governed by such form; provided,
however, that, if at the date of the Assignment and Acceptance pursuant to which a Lender
assignee becomes a party to this Agreement, the Lender assignor was entitled to payments under
subsection (a) in respect of United States withholding tax with respect to interest paid at such
date, then, to such extent, the term “Taxes” shall include (in addition to withholding taxes that
may be imposed in the future or other amounts otherwise includable in Taxes) United States
withholding tax, if any, applicable with respect to the Lender assignee on such date. If any form
or document referred to in this subsection (e) requires the disclosure of

27

 

information, other than information necessary to compute the tax payable and information
required on the date hereof by Internal Revenue Service Form W-8BEN or W-8ECI, that the Lender
reasonably considers to be confidential, the Lender shall give notice thereof to the Borrower and
shall not be obligated to include in such form or document such confidential information.

          (f) For any period with respect to which a Lender has failed to provide the Borrower with the
appropriate form, certificate or other document described in Section 2.14(e) (other than if such
failure is due to a change in law, or in the interpretation or application thereof, occurring
subsequent to the date on which a form, certificate or other document originally was required to be
provided, or if such form, certificate or other document otherwise is not required under subsection
(e) above), such Lender shall not be entitled to indemnification under Section 2.14(a) or (c) with
respect to Taxes imposed by the United States by reason of such failure; provided,
however, that should a Lender become subject to Taxes because of its failure to deliver a
form, certificate or other document required hereunder, the Borrower shall take such steps as the
Lender shall reasonably request to assist the Lender to recover such Taxes.

          (g) If the Agent or any Lender determines, in its sole discretion, that it has received a
refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with
respect to which the Borrower has paid additional amounts pursuant to this Section 2.14, it shall
pay over such refund to the Borrower (but only to the extent of indemnity payments made, or
additional amounts paid, by the Borrower under this Section 2.14 with respect to the Taxes or Other
Taxes giving rise to such refund), net of all out-of-pocket expenses of the Agent or such Lender
and without interest (other than any interest paid by the relevant governmental authority with
respect to such refund); provided, that the Borrower, upon the request of the Agent or such
Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other
charges imposed by the relevant governmental authority) to the Agent or such Lender in the event
the Agent or such Lender is required to repay such refund to such governmental authority. This
paragraph shall not be construed to require the Agent or any Lender to make available its tax
returns (or any other information relating to its taxes which it deems confidential) to the
Borrower or any other Person.

          (h) Any Lender claiming any additional amounts payable pursuant to this Section 2.14 agrees to
use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions)
to change the jurisdiction of its Eurodollar Lending Office if the making of such a change would
avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue
and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such
Lender.

          SECTION 2.15. Sharing of Payments, Etc. If any Lender shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on
account of the Advances owing to it (other than pursuant to Section 2.11, 2.14 or 8.04(c)) in
excess of its ratable share of payments on account of the Advances obtained by all the Lenders,
such Lender shall forthwith purchase from the other Lenders such participations in the Advances
owing to them as shall be necessary to cause such purchasing Lender to share the excess payment
ratably with each of them; provided, however, that if all or any portion of such
excess payment is thereafter recovered from such purchasing Lender, such purchase from each

28

 

Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase
price to the extent of such recovery together with an amount equal to such Lender’s ratable share
(according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the
total amount so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered provided
further that, so long as the maturity of the obligations under this Agreement and the Notes
shall not have been accelerated, any excess payment received by any Lender shall be shared on a pro
rata basis only with other Lenders. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 2.15 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of set-off) with respect
to such participation as fully as if such Lender were the direct creditor of the Borrower in the
amount of such participation.

          SECTION 2.16. Evidence of Debt. (a) Each Lender shall maintain in accordance with
its usual practice an account or accounts evidencing the indebtedness of the Borrower to such
Lender resulting from each Advance owing to such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time hereunder in respect of
Advances. The Borrower agrees that upon notice by any Lender to the Borrower (with a copy of such
notice to the Agent) to the effect that a Note is required or appropriate in order for such Lender
to evidence (whether for purposes of pledge, enforcement or otherwise) the Advances owing to, or to
be made by, such Lender, the Borrower shall promptly execute and deliver to such Lender a Note in
substantially the form of Exhibit A hereto, payable to the order of such Lender in a principal
amount equal to the Revolving Credit Commitment of such Lender.

          (b) The Register maintained by the Agent pursuant to Section 8.07(d) shall include a control
account, and a subsidiary account for each Lender, in which accounts (taken together) shall be
recorded (i) the date and amount of each Borrowing made hereunder, the Type of Advances comprising
such Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the terms of each
Assumption Agreement and each Assignment and Acceptance delivered to and accepted by it, (iii) the
amount of any principal or interest due and payable or to become due and payable from the Borrower
to each Lender hereunder and (iv) the amount of any sum received by the Agent from the Borrower
hereunder and each Lender’s share thereof.

          (c) Entries made in good faith by the Agent in the Register pursuant to subsection (b) above,
and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima
facie evidence of the amount of principal and interest due and payable or to become due and payable
from the Borrower to, in the case of the Register, each Lender and, in the case of such account or
accounts, such Lender, under this Agreement, absent manifest error; provided,
however, that the failure of the Agent or such Lender to make an entry, or any finding that
an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise
affect the obligations of the Borrower under this Agreement.

          SECTION 2.17. Use of Proceeds. The proceeds of the Advances shall be available (and
the Borrower agrees that it shall use such proceeds) for refinancing of the Prior Facility and for
general corporate purposes of the Borrower and its Subsidiaries, including commercial paper
backstop and acquisition financing.

29

 

          SECTION 2.18. Increase in the Aggregate Revolving Credit Commitments. (a) The
Borrower may, at any time but in any event not more than once in any calendar year prior to the
Termination Date, by notice to the Agent, request that the aggregate amount of the Revolving Credit
Commitments be increased by an amount of at least $10,000,000 or an integral multiple thereof (each
a “Commitment Increase”) to be effective as of a date that is at least 90 days prior to the
scheduled Termination Date then in effect (the “Increase Date”) as specified in the related
notice to the Agent; provided, however that (i) in no event shall the aggregate
amount of the Revolving Credit Commitments at any time exceed $1,000,000,000 and (ii) on the date
of any request by the Borrower for a Commitment Increase and on the related Increase Date the
conditions set forth in Section 3.02 shall have been satisfied.

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

          (c) Promptly following each Commitment Date, the Agent shall notify the Borrower as to the
amount, if any, by which the Lenders are willing to participate in the requested Commitment
Increase. If the aggregate amount by which the Lenders are willing to participate in any requested
Commitment Increase on any such Commitment Date is less than the requested Commitment Increase,
then the Borrower may extend offers to one or more Eligible Assignees to participate in any portion
of the requested Commitment Increase that has not been committed to by the Lenders as of the
applicable Commitment Date; provided, however, that the Revolving Credit Commitment
of each such Eligible Assignee shall be in an amount of $5,000,000 or an integral multiple of
$1,000,000 in excess thereof.

          (d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a
requested Commitment Increase in accordance with Section 2.18(c) (each such Eligible Assignee, an
“Assuming Lender”) shall become a Lender party to this Agreement as of such Increase Date
and the Revolving Credit Commitment of each Increasing Lender for such requested Commitment
Increase shall be so increased by such amount (or by the amount allocated to such Lender pursuant
to the last sentence of Section 2.18(b)) as of such Increase Date; provided,
however, that the Agent shall have received on or before such Increase Date the following,
each dated such date:

     (i) (A) certified copies of resolutions of the Board of Directors of the Borrower or
the Executive Committee of such Board approving the Commitment Increase and the
corresponding modifications to this Agreement and (B) an opinion of

30

 

counsel for the Borrower (which may be in-house counsel), in substantially the form of
Exhibit D hereto;

     (ii) an assumption agreement from each Assuming Lender, if any, in form and substance
satisfactory to the Borrower and the Agent (each an “Assumption Agreement”), duly
executed by such Assuming Lender, the Agent and the Borrower; and

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

On each Increase Date, upon fulfillment of the conditions set forth in the immediately preceding
sentence of this Section 2.18(d) and in Section 3.02, the Agent shall notify the Lenders
(including, without limitation, each Assuming Lender) and the Borrower, on or before 1:00 P.M. (New
York City time), by telecopier, of the occurrence of the Commitment Increase to be effected on such
Increase Date and shall record in the Register the relevant information with respect to each
Increasing Lender and each Assuming Lender on such date.

          (e) On the Increase Date, if any Advances are then outstanding, the Borrower shall borrow from
all or certain of the Lenders and/or (subject to compliance by the Borrower with Section 8.04(c))
prepay Advances of all or certain of the Lenders such that, after giving effect thereto, the
Advances (including, without limitation, the Types and Interest Periods thereof) shall be held by
the Lenders (including for such purposes the Increasing Lenders and the Assuming Lenders) ratably
in accordance with their respective Revolving Credit Commitments. On and after each Increase Date,
the Ratable Share of each Lender’s participation in Letters of Credit and Advances from draws under
Letters of Credit shall be calculated after giving effect to each such Commitment Increase.

          SECTION 2.19. Extension of Termination Date.

          (a) The Borrower may, by notice to the Agent (which shall promptly notify the Lenders) not
less than 45 days and not more than 90 days prior to each of the first and second anniversaries of
the Effective Date (each anniversary, an “Anniversary Date”), request that each Lender
extend such Lender’s Termination Date to the date (the “New Termination Date”) that is one
year after the then Termination Date. Each Lender, acting in its sole discretion, shall, by
written notice to the Agent given no later than the date (the “Consent Date”) that is 20
days prior to the relevant Anniversary Date (provided that, if such date is not a Business
Day, the Consent Date shall be the next succeeding Business Day), advise the Agent as to:

     (i) whether such Lender agrees to such extension of its Termination Date (each Lender
so agreeing to such extension being an “Extending Lender”); and

     (ii) only if such Lender is an Extending Lender, whether such Lender also irrevocably
offers to increase the amount of its Revolving Credit Commitment in connection with the
replacement of one or more Non-Extending Lenders (each Lender so offering to increase its
Revolving Credit Commitment being an “Increasing and Extending Lender” as well as an
Extending Lender) and, if so, the amount of the

31

 

additional Commitment such Lender so irrevocably offers to assume hereunder (such
Lender’s “Proposed Additional Commitment”).

Each Lender that determines not to extend its Termination Date (a “Non-Extending Lender”)
shall notify the Agent (which shall notify the Lenders) of such fact promptly after such
determination but in any event no later than the Consent Date, and any Lender that does not advise
the Agent in writing on or before the Consent Date shall be deemed to be a Non-Extending Lender and
(without limiting the Borrower’s rights under Section 2.19(c)) shall have no liability to the
Borrower in connection therewith. The election of any Lender to agree to such extension shall not
obligate any other Lender so to agree. The Agent shall notify the Borrower of each Lender’s
determination under this Section 2.19(a) no later than the date 15 days prior to the relevant
Anniversary Date (or, if such date is not a Business Day, on the next preceding Business Day).

     (b) (i) If all of the Lenders are Extending Lenders, then, effective as of the Consent
Date, the Termination Date of each Lender shall be extended to the New Termination Date as
provided in Section 2.19(b)(ii)(1), and the respective Revolving Credit Commitments of the
Lenders will not be subject to change at such Consent Date pursuant to this Section 2.19.

     (ii) If and only if the sum of (x) the aggregate amount of the Revolving Credit
Commitments of the Extending Lenders (that are not Increasing and Extending Lenders)
plus (y) the aggregate amount of the Proposed Additional Commitments of the
Increasing and Extending Lenders (such sum, the “Extending Commitments”) shall be
equal to at least 50% of the then total Revolving Credit Commitments, then:

     (1) effective as of the Consent Date, the Termination Date of each Extending
Lender shall be extended to the New Termination Date;

     (2) the Borrower shall (so long as no Default shall have occurred and be
continuing) have the right, but not the obligation, during the period commencing on
the Consent Date and ending on the immediately succeeding Anniversary Date to
replace each Non-Extending Lender as a party to this Agreement in accordance with
Section 2.19(c); and

     (3) the Agent shall notify the Issuing Banks of the New Termination Date and
the Lenders whose Termination Dates are the New Termination Date, and each Issuing
Bank, acting in its sole discretion, shall determine whether it shall elect to
extend its Termination Date to the New Termination Date and shall so notify the
Agent, at which time such Issuing Bank’s obligation to issue Letters of Credit
pursuant to Section 2.03 shall be extended to the date that is 30 days prior to the
New Termination Date.

     (iii) If neither of the conditions specified in clause (i) or clause (ii) of this
Section 2.19(b) is satisfied, then neither the Termination Date nor the Commitment of any
Lender will change pursuant to this Section 2.19 on such Consent Date, and the

Borrower will not have the right to take any of the actions specified in Section
2.19(b)(ii)(2).

          (c) Replacement by the Borrower of Non-Extending Lenders pursuant to Section 2.19(b)(ii)(2)
shall be effected as follows (certain terms being used in this Section 2.19(c) having the meanings
assigned to them in Section 2.19(d)) on the relevant Assignment Date:

     (i) the Assignors shall severally assign and transfer to the Assignees, and the
Assignees shall severally purchase and assume from the Assignors, all of the Assignors’
rights and obligations (including, without limitation, the Assignors’ respective Revolving
Credit Commitments) hereunder and under the Notes;

     (ii) each Assignee shall pay to the Agent, for account of the Assignors, an amount
equal to such Assignee’s Share of the aggregate outstanding principal amount of the Advances
then held by the Assignors; and

     (iii) the Borrower shall pay to the Agent, for account of the Assignors, all interest,
fees and other amounts (other than principal of outstanding Advances) then due and owing to
the Assignors by the Borrower hereunder (including, without limitation, payments due such
Assignors, if any, under Sections 2.11, 2.14 and 8.04).

The assignments provided for in this Section 2.19(c) shall be effected on the relevant Assignment
Date in accordance with Section 8.07 and pursuant to one or more Assignments and Acceptances.
After giving effect to such assignments, each Assignee shall have a Revolving Credit Commitment
hereunder (which, if such Assignee was a Lender hereunder immediately prior to giving effect to
such assignment, shall be in addition to such Assignee’s existing Revolving Credit Commitment) in
an amount equal to the amount of its Assumed Commitment. Upon any such termination or assignment,
each Assignor shall cease to be a party hereto to the extent of its assignment but shall continue
to be obligated under Section 7.05 and be entitled to the benefits of Section 8.04, as well as to
any fees and other amounts accrued for its account under Sections 2.04, 2.11 or 2.14 and not yet
paid.

          (d) For purposes of this Section 2.19 the following terms shall have the following meanings
(such meanings to be equally applicable to both the singular and plural forms of the terms
defined):

          “Assigned Commitments” means the Commitments of Non-Extending Lenders to be replaced
pursuant to Section 2.19(b)(ii)(2).

          “Assignees” means, at any time, Increasing and Extending Lenders and, if the Assigned
Commitments exceed the aggregate amount of the Proposed Additional Commitments, one or more New
Lenders.

          “Assignment Date” means the relevant Anniversary Date or such earlier date as shall be
acceptable to the Borrower, the relevant Assignors, the relevant Assignees and the Agent.

33

 

          “Assignors” means, at any time, the Non-Extending Lenders to be replaced by the
Borrower pursuant to Section 2.19(b)(ii)(2).

          The “Assumed Commitment” of each Assignee shall be determined as follows:

          (a) If the aggregate amount of the Proposed Additional Commitments of all of the Increasing
Lenders shall exceed the aggregate amount of the Assigned Commitments, then (i) the amount of the
Assumed Commitment of each Increasing and Extending Lender shall be equal to (x) the aggregate
amount of the Assigned Commitments multiplied by (y) a fraction, the numerator of
which is equal to such Increasing and Extending Lender’s Commitment as then in effect and the
denominator of which is the aggregate amount of the Commitments of all Increasing and Extending
Lenders as then in effect; and (ii) no New Lender shall be entitled to become a Lender hereunder
pursuant to Section 2.19(c) (and, accordingly, each New Lender shall have an Assumed Commitment of
zero).

          (b) If the aggregate amount of the Proposed Additional Commitments of all of the Increasing
and Extending Lenders shall be less than or equal to the aggregate amount of the Assigned
Commitments, then: (i) the amount of the Assumed Commitment of each Increasing and Extending
Lender shall be equal to such Increasing and Extending Lender’s Proposed Additional Commitment; and
(ii) the excess, if any, of the aggregate amount of the Assigned Commitments over the
aggregate amount of the Proposed Additional Commitments shall be allocated among New Lenders in
such a manner as the Borrower and the Agent may agree.

          (c) “Share” means, as to any Assignee, a fraction the numerator of which is equal to
such Assignee’s Assumed Commitment and the denominator of which is the aggregate amount of the
Assumed Commitments of all the Assignees.

          SECTION 2.20. Termination of Commitments under Prior Facility. Simultaneously with
the Effective Date and the repayment of the loans under the Prior Facility, the Revolving Credit
Commitments and the Term Loan Commitments (each as defined in the Prior Facility) shall be
terminated in whole and replaced with the Revolving Credit Commitments of the Lenders hereunder.

and effect.

          (d) This Agreement has been, and each of the Notes to be delivered by it when delivered
hereunder will have been, duly executed and delivered by the Borrower. This Agreement is, and each
of the Notes when delivered hereunder will be, the legal, valid and binding obligation of the

enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the enforcement of creditors’ rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or at law).

          (e) The Consolidated balance sheet of the Borrower and its Subsidiaries as at December 31,
2006, and the related Consolidated statements of income and cash flows of the Borrower and its

income and cash flows for the three months then ended, to year-end audit

37

 

adjustments, the Consolidated financial condition of the Borrower and its Subsidiaries as at
such dates and the Consolidated results of the operations of the Borrower and its Subsidiaries for
the periods ended on such dates, all in accordance with generally accepted accounting principles
consistently applied. Since December 31, 2006, there has been no Material Adverse Change.

          (f) There is no pending or threatened action, suit, investigation, litigation or proceeding
affecting the Borrower or any of its Subsidiaries before any court, governmental agency or

to materially and adversely affect the legality, validity or enforceability of this Agreement or
any Note or the consummation of the transactions contemplated hereby, and there has been no
material adverse change in the status, or in the financial effect on the Borrower and its

purchasing or carrying margin stock (within the meaning of Regulation U issued by the Board of
Governors of the Federal Reserve System (the “Board”)), and no proceeds of any Advance will
be used to purchase or carry any margin stock or to extend credit to others for the purpose of

negotiation and syndication of this Agreement or pursuant to the terms of this Agreement contained,
as of the respective dates thereof, any untrue statement of a material fact or omitted to state a
material fact necessary to make the statements made therein, taken as a whole, not misleading. The
projections and pro forma financial information contained in the material referenced above are
based upon good faith estimates and assumptions believed by management of the Borrower to be
reasonable at the time made, it being recognized by the Lenders that such financial information as
it relates to future events is not to be viewed as fact and that actual results during the period
or periods covered by such financial information may differ from the projected results set forth
therein by a material amount.

          (j) Except as disclosed to the Agent by the Borrower in writing from time to time after the
Closing Date, Schedule 4.01(j) sets forth the name and jurisdiction of incorporation of each
Subsidiary of the Borrower and, as to each such Subsidiary, the percentage of each class of capital

Subsidiary or an Insurance Subsidiary.

          (k) The Borrower and each of its Subsidiaries has filed or caused to be filed all Federal and
other material tax returns that are required to be filed and has paid all taxes shown to be due and
payable on said returns or on any assessments made against it or any of its

38

 

property and all other taxes, fees or other charges imposed on it or any of its property by
any governmental authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which reserves in conformity
with GAAP have been provided on the books of the Borrower or such Subsidiary). No tax Lien has
been filed and, to the knowledge of the Borrower, no claim is being asserted, with respect to any
such tax, fee or other charge.

COVENANTS OF THE BORROWER

          SECTION 5.01. Affirmative Covenants. So long as any Advance shall remain unpaid or
any Lender shall have any Commitment hereunder, the Borrower will:

          (a) Compliance with Laws, Etc. Comply, and cause each of its Subsidiaries to comply,
with all applicable laws, rules, regulations and orders, such compliance to include, without
limitation, compliance with applicable requirements of ERISA, Environmental Laws, HIPAA, Medicaid
Regulations, HMO Regulations, Insurance Regulations and the Patriot Act, except to the extent that
failure to comply therewith could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.

          (b) Payment of Taxes, Etc. Pay and discharge, and cause each of its Subsidiaries to
pay and discharge, before the same shall become delinquent, (i) all taxes, assessments and
governmental charges or levies imposed upon it or upon its property and (ii) all lawful claims
that, if unpaid, might by law become a Lien upon its property; provided, however,
that neither the Borrower nor any of its Subsidiaries shall be required to pay or discharge any
such tax, assessment, charge or claim (i) that is being contested in good faith and by proper
proceedings and as to which appropriate reserves are being maintained, unless and until any Lien
resulting therefrom attaches to its property and becomes enforceable against its other creditors or
(ii) if a failure to pay or discharge the same, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

          (c) Maintenance of Insurance. Maintain, and cause each of its Subsidiaries to
maintain, such insurance with responsible and reputable insurance companies or associations in such
amounts and covering such risks as is usually carried by companies engaged in similar businesses
and owning similar properties in the same general areas in which the Borrower or such Subsidiary
operates; provided, however, that the Borrower and its Subsidiaries may self-insure
to the same extent as other companies engaged in similar businesses and owning similar properties
in the same general areas in which the Borrower or such Subsidiary operates and to the extent
consistent with prudent business practice.

          (d) Preservation of Corporate Existence, Etc. (i) Preserve and maintain, and cause
each of its Subsidiaries to preserve and maintain, its organizational existence and (ii) take, and

and certifications required pursuant to any HMO Regulations or Insurance Regulations, all
certifications and authorizations necessary to ensure that each of the Borrower’s HMO

39

 

Subsidiaries and Insurance Subsidiaries is eligible for all reimbursements available under HMO
Regulations and Insurance Regulations to the extent applicable to HMOs and insurance companies of
their type and the products provided by them, and all material licenses, permits, authorizations

permitted by Section 5.02(b), (y) the Borrower may permit the dissolution and winding-up of any of
its Subsidiaries if such Subsidiary has no material assets, engages in no material business and has
no material activities other than activities related to the maintenance of its existence and good
standing and (z) in the case of clause (i) above as to Subsidiaries and except in the case of
clause (ii) above, to the extent that failure to do so could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

          (e) Visitation Rights. At any reasonable time and from time to time upon reasonable
prior notice and during normal business hours, permit the Agent or any of the Lenders or any agents
or representatives thereof, to examine and make copies of and abstracts from the records and books
of account of, and visit the properties of, the Borrower and any of its Subsidiaries, and to
discuss the affairs, finances and accounts of the Borrower and any of its Subsidiaries with any of
their officers or directors and with their independent certified public accountants. During the
course of the aforementioned examinations, visits and discussions, representatives of the Agent and
the Lenders may encounter individually identifiable healthcare information or other confidential
information relating to healthcare patients (collectively, the “Confidential Healthcare
Information”). Unless otherwise required by law, the Agent and the Lenders, and their
respective representatives, shall not disclose, compile, aggregate, remove from the properties of
the Borrower or any of its Subsidiaries or record in any manner any Confidential Healthcare
Information, and shall not require the Borrower or any of its Subsidiaries to violate any laws,
regulations or ordinances intended to protect the privacy rights of healthcare patients, including,
without limitation, the Health Insurance Portability and Accountability Act of 1996, as amended,
and the rules and regulations promulgated thereunder.

          (f) Keeping of Books. Keep, and cause each of its Subsidiaries to keep, proper books
of record and account, in which full and correct entries shall be made of all financial
transactions and the assets and business of the Borrower and each such Subsidiary in accordance
with generally accepted accounting principles in effect from time to time.

          (g) Maintenance of Properties, Etc. Except to the extent that a failure to do so

useful in the conduct of its business in good working order and condition, ordinary wear and tear
excepted.

          (h) Transactions with Affiliates. Conduct, and cause each of its Subsidiaries to
conduct, all transactions otherwise permitted under this Agreement with any of their Affiliates
(other than transactions that are not material to the Borrower and its Subsidiaries on a
Consolidated basis and transactions between or among the Borrower and its Subsidiaries) on terms
that are fair and reasonable and no less favorable to the Borrower or such Subsidiary than it would
obtain in a comparable arm’s-length transaction with a Person not an Affiliate.

valid and binding policy of insurance between the defendant and the insurer covering payment
thereof and (ii) such insurer has been notified of, and has not disputed the claim made for payment
of, the amount of such judgment or order; or

          (g) (i) Any Person (other than the Borrower) or two or more Persons acting in concert shall

the combined voting power of all Voting Stock of the Borrower; or (ii) during any period of 24
consecutive months, commencing after the date of this Agreement, individuals who at the beginning
of such 24-month period were directors of the Borrower shall cease for any reason (other than due
to death or disability) to constitute a majority

47

 

of the board of directors of the Borrower (except to the extent that individuals who at the
beginning of such 24-month period were replaced by individuals (x) elected by a majority of the
remaining members of the board of directors of the Borrower or (y) nominated for election by, or
whose nomination for election is recommend by, a majority of the remaining members of the board of
directors of the Borrower and thereafter elected as directors by the shareholders of the Borrower);
or

          (h) The Borrower or any of its ERISA Affiliates shall incur liability in excess of $50,000,000

shall not have been cured or waived within 30 days after the applicable statutory grace period (if
any), if such non-compliance could reasonably be expected to have a Material Adverse Effect;

then, and in any such event, the Agent (i) shall at the request, or may with the consent, of the
Required Lenders, by notice to the Borrower, declare the obligation of each Lender to make Advances
to be terminated, whereupon the same shall forthwith terminate, and (ii) shall at the request, or
may with the consent, of the Required Lenders, by notice to the Borrower, declare the Advances, all
interest thereon and all other amounts payable under this Agreement to be forthwith due and
payable, whereupon the Advances, all such interest and all such amounts shall become and be

the event of an actual or deemed entry of an order for relief with respect to the Borrower under
the Federal Bankruptcy Code, (A) the obligation of each Lender to make Advances shall automatically
be terminated and (B) the Advances, all such interest and all such other amounts shall

having at least 51% of the Revolving Credit Commitments. If at any time the Agent determines that
any funds held in the L/C Cash Collateral Account are subject to any right or claim of any Person
other than the Agent and the Lenders or that the total amount of such funds is less than the
aggregate Available Amount of all

48

 

Letters of Credit, the Borrower will, forthwith upon demand by the Agent, pay to the Agent, as
additional funds to be deposited and held in the L/C Cash Collateral Account, an amount equal to
the excess of (a) such aggregate Available Amount over (b) the total amount of funds, if any, then
held in the L/C Cash Collateral Account that the Agent determines to be free and clear of any such
right and claim. Upon the drawing of any Letter of Credit, to the extent funds are on deposit in
the L/C Cash Collateral Account, such funds shall be applied to reimburse the Issuing Banks to the
extent permitted by applicable law. After (i) no Event of Default shall be continuing or (ii) all
such Letters of Credit shall have expired or been fully drawn upon and all other obligations of the
Borrower hereunder and under the Notes shall have been paid in full, the balance, if any, in such
L/C Cash Collateral Account shall be returned to the Borrower.

ARTICLE VII

THE AGENT

          SECTION 7.01. Authorization and Action. Each Lender (in its capacity as a Lender and
an Issuing Bank, as applicable) hereby appoints and authorizes the Agent to take such action as
agent on its behalf and to exercise such powers and discretion under this Agreement as are
delegated to the Agent by the terms hereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by this Agreement
(including, without limitation, enforcement or collection of the Notes), the Agent shall not be
required to exercise any discretion or take any action, but shall be required to act or to refrain
from acting (and shall be fully protected in so acting or refraining from acting) upon the
instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and
all holders of Notes; provided, however, that the Agent shall not be required to
take any action that exposes the Agent to personal liability or that is contrary to this Agreement
or applicable law. The Agent agrees to give to each Lender prompt notice of each notice given to
it by the Borrower pursuant to the terms of this Agreement.

          SECTION 7.02. Agent’s Reliance, Etc. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable for any action taken or omitted to be taken by it or
them under or in connection with this Agreement, except for its or their own gross negligence or
willful misconduct. Without limitation of the generality of the foregoing, the Agent: (i) may
treat the Lender that made any Advance as the holder of the Debt resulting therefrom until the
Agent receives and accepts an Assumption Agreement entered into by an Assuming Lender as provided
in Section 2.18 or an Assignment and Acceptance entered into by such Lender, as assignor, and an
Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult with legal counsel
(including counsel for the Borrower), independent public accountants and other experts selected by
it and shall not be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any statements,
warranties or representations (whether written or oral) made in or in connection with this
Agreement; (iv) shall not have any duty to ascertain or to inquire as to the performance,
observance or satisfaction of any of the terms, covenants or conditions of this Agreement on the
part of the Borrower or the existence at any time of any Default or to inspect the property
(including the books and records) of the Borrower; (v) shall not be responsible to any Lender for
the due execution, legality, validity, enforceability, genuineness, sufficiency or

49

 

value of, or the perfection or priority of any lien or security interest created or purported
to be created under or in connection with, this Agreement or any other instrument or document
furnished pursuant hereto; and (vi) shall incur no liability under or in respect of this Agreement
by acting upon any notice, consent, certificate or other instrument or writing (which may be by
telecopier or telegram) believed by it to be genuine and signed or sent by the proper party or
parties.

          SECTION 7.03. Citibank and Affiliates. With respect to its Commitments, the Advances
made by it and the Note issued to it, Citibank shall have the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not the Agent; and the
term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Citibank in its
individual capacity. Citibank and its Affiliates may accept deposits from, lend money to, act as
trustee under indentures of, accept investment banking engagements from and generally engage in any
kind of business with, the Borrower, any of its Subsidiaries and any Person who may do business
with or own securities of the Borrower or any such Subsidiary, all as if Citibank were not the
Agent and without any duty to account therefor to the Lenders. The Agent shall have no duty to
disclose any information obtained or received by it or any of its Affiliates relating to the
Borrower or any of its Subsidiaries to the extent such information was obtained or received in any
capacity other than as Agent.

          SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender and based on the financial
statements referred to in Section 4.01 and such other 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 Agent 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.

          SECTION 7.05. Indemnification. (a) Each Lender agrees to indemnify the Agent (to the
extent not promptly reimbursed by the Borrower and without limiting any obligation of the Borrower
to do so) from and against such Lender’s Ratable Share of any and all liabilities, obligations,
losses, damages, actions, judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by, or asserted against the Agent in any way relating
to or arising out of this Agreement or any action taken or omitted by the Agent in its capacity as
such under this Agreement (collectively, the “Indemnified Costs”), provided that no
Lender shall be liable for any portion of the Indemnified Costs resulting from the Agent’s gross
negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to
reimburse the Agent promptly upon demand for its Ratable Share of any out-of-pocket expenses
(including counsel fees) incurred by the Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower.
In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs,
this Section 7.05(a) applies whether any such investigation, litigation or proceeding is brought by
the Agent, any Lender or a third party.

50

 

          (b) Each Lender severally agrees to indemnify the Issuing Banks (to the extent not promptly
reimbursed by the Borrower and without limiting any obligation of the Borrower to do so) from and
against such Lender’s Ratable Share of any and all liabilities, obligations, losses, damages,
actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that
may be imposed on, incurred by, or asserted against any such Issuing Bank in any way relating to or
arising out of this Agreement or any action taken or omitted by such Issuing Bank in its capacity
as such hereunder or in connection herewith; provided, however, that no Lender
shall be liable for any portion of such liabilities, obligations, losses, damages, actions,
judgments, suits, costs, expenses or disbursements resulting from such Issuing Bank’s gross
negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to
reimburse any such Issuing Bank promptly upon demand for its Ratable Share of any costs and
expenses (including, without limitation, fees and expenses of counsel) payable by the Borrower
under Section 8.04, to the extent that such Issuing Bank is not promptly reimbursed for such costs
and expenses by the Borrower.

          (c) The failure of any Lender to reimburse the Agent or the Issuing Bank promptly upon demand
for its Ratable Share of any amount required to be paid by the Lenders to the Agent or the Issuing
Bank as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse
the Agent or the Issuing Bank for its Ratable Share of such amount, but no Lender shall be
responsible for the failure of any other Lender to reimburse the Agent or an Issuing Bank for such
other Lender’s Ratable Share of such amount. Without prejudice to the survival of any other
agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this
Section 7.05 shall survive the payment in full of principal, interest and all other amounts payable
hereunder and under the Notes.

          SECTION 7.06. Successor Agent. The Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause
by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the
right to appoint a successor Agent, which shall be subject to the Borrower’s approval (not to be
unreasonably withheld or delayed) unless an Event of Default has occurred and is continuing. If no
successor Agent shall have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the
Required Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or of any State thereof and having a combined capital and surplus of
at least $500,000,000 and which shall be subject to the Borrower’s approval (not to be unreasonably
withheld or delayed) unless an Event of Default has occurred and is continuing. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, discretion, privileges and
duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations under this Agreement. After any retiring Agent’s resignation or removal hereunder as
Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under this Agreement.

51

 

          SECTION 7.07. Other Agents. Each Lender hereby acknowledges that neither the
documentation agent nor any other Lender designated as any “agent” on the cover or signature pages
hereof has any liability hereunder other than in its capacity as a Lender.

ARTICLE VIII

address as shall be designated by such party in a written notice to the other parties and, as to
each other party, at such other address as shall be designated by such party in a written notice to
the Borrower and the Agent, provided that materials required to be delivered pursuant to
Section 5.01(i)(i), (ii) or (iii) shall be delivered to the Agent as specified in Section 8.02(b)
or as otherwise specified to the Borrower by the Agent. All such notices and communications shall,
when mailed, telecopied, telegraphed or e-mailed, be effective when deposited in the mails,
telecopied, delivered to the telegraph company or confirmed by e-mail, respectively, except that
notices and communications to the Agent pursuant to Article II, III or VII shall not be effective
until received by the Agent. Delivery by telecopier or e-mail of an executed counterpart of any
amendment or waiver of any provision of this Agreement or the Notes or of any Exhibit hereto to be
executed and delivered hereunder shall be effective as delivery of a manually executed counterpart
thereof.

          (b) So long as Citibank or any of its Affiliates is the Agent, materials required to be
delivered pursuant to Section 5.01(i)(i), (ii) and (iii) shall be either (x) delivered to the Agent
in an electronic medium in a format acceptable to the Agent and the Lenders by e-mail at
oploanswebadmin@citigroup.com or (y) deemed to have been delivered when the Borrower provides
notice to the Agent by e-mail at oploanswebadmin@citigroup.com that such materials are posted on
the SEC’s website at www.sec.gov. The Borrower agrees that the Agent may make such materials, as
well as any other written information, documents, instruments and other material relating to the
Borrower, any of its Subsidiaries or any other materials or matters relating to this Agreement, the
Notes or any of the transactions contemplated hereby (collectively, the “Communications”)
available to the Lenders by posting such notices on Intralinks or a substantially similar
electronic system (the “Platform”). The Borrower acknowledges that (i) the distribution of
material through an electronic medium is not necessarily secure and that there are confidentiality
and other risks associated with such distribution, (ii) the Platform is provided “as is” and “as
available” and (iii) neither the Agent nor any of its Affiliates warrants the accuracy, adequacy or
completeness of the Communications or the Platform and each expressly disclaims liability for
errors or omissions in the Communications or the Platform. No warranty of any kind, express,
implied or statutory, including, without limitation, any warranty of merchantability, fitness for a
particular purpose, non-infringement of third party rights or freedom from viruses or other code
defects, is made by the Agent or any of its Affiliates in connection with the Platform.

          (c) Each Lender agrees that notice to it (as provided in the next sentence) (a
“Notice”) specifying that any Communications have been posted to the Platform shall
constitute effective delivery of such information, documents or other materials to such Lender for
purposes of this Agreement; provided that if requested by any Lender the Agent shall
deliver a copy of the Communications to such Lender by email or telecopier. Each Lender agrees (i)
to notify the Agent in writing of such Lender’s e-mail address to which a Notice may be sent by
electronic transmission (including by electronic communication) on or before the date such Lender
becomes a party to this Agreement (and from time to time thereafter to ensure that the Agent has

53

 

on record an effective e-mail address for such Lender) and (ii) that any Notice may be sent to
such e-mail address.

          SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender or the Agent
to exercise, and no delay in exercising, any right hereunder or under any Note shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right preclude any other or
further exercise thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

          SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to pay on demand all
reasonable costs and expenses of the Agent in connection with the preparation, execution, delivery,
administration, modification and amendment of this Agreement, the Notes and the other documents to
be delivered hereunder, including, without limitation, (A) all due diligence, syndication
(including printing, distribution and bank meetings), transportation, computer, duplication,
appraisal, consultant, and audit expenses (subject to any limitations thereon previously agreed by
the Borrower and the Agent) and (B) the reasonable fees and expenses of counsel for the Agent with
respect thereto and with respect to advising the Agent as to its rights and responsibilities under
this Agreement. The Borrower further agrees to pay on demand all costs and expenses of the Agent
and the Lenders, if any (including, without limitation, reasonable counsel fees and expenses), in
connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of
this Agreement, the Notes and the other documents to be delivered hereunder, including, without
limitation, reasonable fees and expenses of counsel for the Agent and each Lender in connection
with the enforcement of rights under this Section 8.04(a).

          (b) The Borrower agrees to indemnify and hold harmless the Agent and each Lender and each of
their Affiliates and their officers, directors, employees, agents and advisors (each, an
“Indemnified Party”) from and against any and all claims, damages, losses, liabilities and
expenses (including, without limitation, reasonable fees and expenses of counsel) incurred by or
asserted or awarded against any Indemnified Party, in each case arising out of or in connection
with or by reason of (including, without limitation, in connection with any investigation,
litigation or proceeding or preparation of a defense in connection therewith) the Notes, this
Agreement, any of the transactions contemplated herein or the actual or proposed use of the
proceeds of the Advances, except to the extent such claim, damage, loss, liability or expense is
found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted
from such Indemnified Party’s gross negligence or willful misconduct. In the case of an
investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b)
applies, such indemnity shall be effective whether or not such investigation, litigation or
proceeding is brought by the Borrower, its directors, equityholders or creditors or an Indemnified
Party or any other Person, whether or not any Indemnified Party is otherwise a party thereto and
whether or not the transactions contemplated hereby are consummated. The Borrower also agrees not
to assert any claim for special, indirect, consequential or punitive damages against the Agent, any
Lender, any of their Affiliates, or any of their respective directors, officers, employees,
attorneys and agents, on any theory of liability, arising out of or otherwise relating to the
Notes, this Agreement, any of the transactions contemplated herein or the actual or proposed use of
the proceeds of the Advances. The Borrower further agrees to pay any civil penalty or fine
assessed by OFAC against the Agent or any Lender and all reasonable costs and expenses

54

 

(including, without limitation, reasonable counsel fees and expenses) incurred in connection
with the defense thereof, as a result of conduct by the Borrower that violates a sanction enforced
by OFAC.

          (c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by
the Borrower to or for the account of a Lender other than on the last day of the Interest Period
for such Advance, as a result of a payment or Conversion pursuant to Section 2.08(e), 2.10 or 2.12,
acceleration of the maturity of the Notes pursuant to Section 6.01 or for any other reason, or by
an Eligible Assignee to a Lender other than on the last day of the Interest Period for such Advance
upon an assignment of rights and obligations under this Agreement pursuant to Section 8.07 as a
result of a demand by the Borrower pursuant to Section 8.07(a), the Borrower shall, upon demand by
such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such
Lender any amounts required to compensate such Lender for any additional losses, costs or expenses
that it may reasonably incur as a result of such payment or Conversion, including, without
limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Advance (but without duplication of any obligation of the Borrower under Section 2.11
or any other provision of this Agreement).

          (d) Without prejudice to the survival of any other agreement of the Borrower hereunder, the
agreements and obligations of the Borrower contained in Sections 2.11, 2.14 and 8.04 shall survive
the payment in full of principal, interest and all other amounts payable hereunder and under the
Notes.

          SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the continuance of
any Event of Default and (ii) the making of the request or the granting of the consent specified by
Section 6.01 to authorize the Agent to declare the Notes due and payable pursuant to the provisions
of Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from
time to time, to the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and other indebtedness
at any time owing by such Lender or such Affiliate to or for the credit or the account of the
Borrower against any and all of the obligations of the Borrower now or hereafter existing under
this Agreement and the Note held by such Lender, whether or not such Lender shall have made any
demand under this Agreement or such Note and although such obligations may be unmatured. Each
Lender agrees promptly to notify the Borrower after any such set-off and application,
provided that the failure to give such notice shall not affect the validity of such set-off
and application. The rights of each Lender and its Affiliates under this Section are in addition
to other rights and remedies (including, without limitation, other rights of set-off) that such
Lender and its Affiliates may have.

          SECTION 8.06. Binding Effect. This Agreement shall become effective (other than
Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set
forth in Section 3.01) when it shall have been executed by the Borrower and the Agent and when the
Agent shall have been notified by each Initial Lender that such Initial Lender has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent and each
Lender and their respective successors and assigns, except that the

55

 

Borrower shall not have the right to assign its rights hereunder or any interest herein
without the prior written consent of the Lenders.

          SECTION 8.07. Assignments and Participations. (a) Each Lender may and, if demanded
by the Borrower (following a demand by such Lender pursuant to Section 2.11 or 2.14 or a suspension
of Eurodollar Rate Advances pursuant to Section 2.12 and only if no Event of Default has occurred
and is continuing) upon at least five Business Days’ notice to such Lender and the Agent, will
assign to one or more Persons all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Revolving Credit Commitment, the Advances
owing to it, its participations in Letters of Credit and the Note or Notes held by it);
provided, however, that (i) each such assignment shall be of a constant, and not a
varying, percentage of all rights and obligations under and in respect of the Facilities so
assigned, (ii) except in the case of an assignment to a Person that, immediately prior to such
assignment, was a Lender or an Affiliate of a Lender or an assignment of all of a Lender’s rights
and obligations under this Agreement, the amount of the Revolving Credit Commitment of the
assigning Lender being assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be less than
$10,000,000 or an integral multiple of $1,000,000 in excess thereof, unless the Borrower and the
Agent otherwise agree, (iii) each such assignment shall be to an Eligible Assignee, (iv) each such
assignment made as a result of a demand by the Borrower pursuant to this Section 8.07(a) shall be
arranged by the Borrower after consultation with the Agent and shall be either an assignment of all
of the rights and obligations of the assigning Lender under this Agreement or an assignment of a
portion of such rights and obligations made concurrently with another such assignment or other such
assignments that together cover all of the rights and obligations of the assigning Lender under
this Agreement, (v) no Lender shall be obligated to make any such assignment as a result of a
demand by the Borrower pursuant to this Section 8.07(a) unless and until such Lender shall have
received, as consideration for such assignment, one or more payments from either the Borrower or
one or more Eligible Assignees in an aggregate amount at least equal to the aggregate outstanding
principal amount of the Advances owing to such Lender, together with accrued interest thereon to
the date of payment of such principal amount and all other amounts payable to such Lender under
this Agreement, and (vi) the parties to each such assignment shall execute and deliver to the
Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together
with any Note subject to such assignment and a processing and recordation fee of $3,500 payable by
the parties to each such assignment other than the Borrower, provided, however,
that in the case of each assignment made as a result of a demand by the Borrower, such recordation
fee shall be payable by the Borrower except that no such recordation fee shall be payable in the
case of an assignment made at the request of the Borrower to an Eligible Assignee that is an
existing Lender. Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a
party hereto and, to the extent that rights and obligations hereunder have been assigned to it
pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder
and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other
than its rights under Sections 2.11, 2.14 and 8.04 to the extent any claim thereunder relates to an
event arising prior to such assignment) and be released from its obligations under this Agreement
(and, in the case of an

56

 

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).

          (b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder
and the assignee thereunder confirm to and agree with each other and the other parties hereto as
follows: (i) other than as provided in such Assignment and Acceptance, 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, or the perfection or
priority of any lien or security interest created or purported to be created under or in connection
with, this Agreement or any other instrument or document furnished pursuant hereto; (ii) such
assigning Lender makes no representation or warranty and assumes no responsibility with respect to
the financial condition of the Borrower or the performance or observance by the Borrower of any of
its obligations under this Agreement or any other instrument or document furnished pursuant hereto;
(iii) such assignee confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 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; (iv) such assignee will, independently and without reliance upon the 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; (v) such assignee confirms that it is an Eligible Assignee; (vi) such
assignee appoints and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms
hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii)
such assignee agrees that it will perform in accordance with their terms all of the obligations
that by the terms of this Agreement are required to be performed by it as a Lender.

          (c) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an
assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to
such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record
the information contained therein in the Register and (iii) give prompt notice thereof to the
Borrower.

          (d) The Agent shall maintain at its address referred to in Section 8.02 a copy of each
Assumption Agreement and each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Advances owing to, each Lender from time to time (the “Register”).
The entries in the Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in
the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower or any Lender at any reasonable time and from time to time
upon reasonable prior notice.

          (e) Each Lender may sell participations to one or more banks or other entities (other than the
Borrower or any of its Affiliates) in or to all or a portion of its rights and

57

 

obligations under this Agreement (including, without limitation, all or a portion of its
Commitment, the Advances owing to it and any Note or Notes held by it); provided,
however, that (i) such Lender’s obligations under this Agreement (including, without
limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties hereto for the performance of such
obligations, (iii) such Lender shall remain the holder of any such Note for all purposes of this
Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement and (v) no participant under any such participation shall have any right to approve any
amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure
by the Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce
the principal of, or interest on, the Notes or any fees or other amounts payable hereunder subject
to such participation, in each case to the extent subject to such participation, or postpone any
date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts
payable hereunder, in each case to the extent subject to such participation.

          (f) Any Lender may, in connection with any assignment or participation or proposed assignment
or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed
assignee or participant, any information relating to the Borrower furnished to such Lender by or on
behalf of the Borrower; provided that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree to preserve the confidentiality of any
Borrower Information relating to the Borrower received by it from such Lender.

          (g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any
time create a security interest in all or any portion of its rights under this Agreement
(including, without limitation, the Advances owing to it and any Note or Notes held by it) in favor
of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the
Federal Reserve System.

          (h) Notwithstanding anything to the contrary contained herein, if at any time any Lender that
is also an Issuing Bank assigns all of its Revolving Credit Commitment and Advances pursuant to
subsection (a) above, such Lender may, upon 30 days’ notice to the Borrower and the Lenders, resign
as Issuing Bank. In the event of any such resignation as Issuing Bank, the Borrower shall be
entitled to appoint from among the Lenders a successor Issuing Bank hereunder; provided,
however, that no failure by the Borrower to appoint any such successor shall affect the
resignation of such Lender as Issuing Bank. If any such Lender resigns as Issuing Bank, it shall
retain all the rights and obligations of an Issuing Bank hereunder with respect to all Letters of
Credit issued by it in such capacity outstanding as of the effective date of its resignation as
Issuing Bank (including the right to require the Lenders to make Advances or fund participations in
respect thereof pursuant to Section 2.03(b)).

          SECTION 8.08. Confidentiality. Each of the Agent, the Lenders and each Issuing Bank
agrees to maintain the confidentiality of the Borrower Information (as defined below), except that
Borrower Information may be disclosed (a) to its Affiliates and to its and its Affiliates’
respective managers, administrators, trustees, partners, directors, officers, employees, agents,
advisors and other representatives on a “need to know basis” (it being understood that the

58

 

Persons to whom such disclosure is made will be informed of the confidential nature of such
Borrower Information and instructed to keep such Borrower Information confidential), (b) to the
extent requested by any regulatory authority purporting to have jurisdiction over it (including any
self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the
extent required by applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder
or under any other Loan Document or any action or proceeding relating to this Agreement or any
other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an
agreement containing provisions substantially the same as those of this Section 8.08, to (i) any
assignee of or participant in, or any prospective assignee of or participant in, any of its rights
or obligations under this Agreement or (ii) any actual or prospective party (or its managers,
administrators, trustees, partners, directors, officers, employees, agents, advisors and other
representatives) to any swap or derivative or similar transaction under which payments are to be
made by reference to the Borrower and its obligations, this Agreement or payments hereunder, (iii)
any rating agency in connection with the rating of the Borrower or its obligations, or (iv) the
CUSIP Service Bureau or any similar organization, (g) with the consent of the Borrower or (h) to
the extent such Borrower Information (x) becomes publicly available other than as a result of a
breach of this Section 8.08 or (y) becomes available to the Agent, any Lender, any Issuing Bank or
any of their respective Affiliates on a nonconfidential basis from a source other than the
Borrower.

          For purposes of this Section 8.08, “Borrower Information” means all information
received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its
Subsidiaries or any of their respective businesses, other than any such information that is
available to the Agent, any Lender or any Issuing Bank on a nonconfidential basis prior to
disclosure by the Borrower or any of its Subsidiaries, provided that, in the case of
information received from the Borrower or any of its Subsidiaries after the date hereof, such
information is clearly identified at the time of delivery as confidential. Any Person required to
maintain the confidentiality of Borrower 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 Borrower Information as such Person would
accord to its own confidential information.

          SECTION 8.09. Governing Law. This Agreement and the Notes shall be governed by, and
construed in accordance with, the laws of the State of New York.

          SECTION 8.10. Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and
the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by
telecopier shall be effective as delivery of a manually executed counterpart of this Agreement.

          SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties hereto 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

59

 

out of or relating to this Agreement or the Notes, 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 any such New York
State court or, to the extent permitted by law, in such federal court. The Borrower hereby
consents to the service of process in any action or proceeding in such courts by the mailing
thereof by any parties hereto by registered or certified mail, postage prepaid, to the Borrower at
its address specified pursuant to Section 8.02. 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 any party may otherwise have to bring any action or
proceeding relating to this Agreement or the Notes in the courts of any jurisdiction.

          (b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent
it may legally and effectively do so, any objection that 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
Notes 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.

          SECTION 8.12. No Liability of the Issuing Banks. The Borrower assumes all risks of
the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its
use of such Letter of Credit. Neither an Issuing Bank nor any of its officers or directors shall
be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or
omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency
or genuineness of documents, or of any endorsement thereon, even if such documents should prove to
be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by such Issuing
Bank against presentation of documents that do not comply with the terms of a Letter of Credit,
including failure of any documents to bear any reference or adequate reference to the Letter of
Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any
Letter of Credit; except that the Borrower shall have a claim against such Issuing Bank, and such
Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential,
damages suffered by the Borrower that the Borrower proves were caused by (i) such Issuing Bank’s
willful misconduct or gross negligence in determining whether documents presented under any Letter
of Credit comply with the terms of the Letter of Credit or (ii) such Issuing Bank’s willful failure
to make lawful payment under a Letter of Credit after the presentation to it of a draft and
certificates strictly complying with the terms and conditions of the Letter of Credit. In
furtherance and not in limitation of the foregoing, such Issuing Bank may accept documents that
appear on their face to be in order, without responsibility for further investigation.

          SECTION 8.13. Patriot Act Notice. Each Lender and the Agent (for itself and not on
behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the Patriot
Act, it is required to obtain, verify and record information that identifies the Borrower, which
information includes the name and address of the Borrower and other information that will allow
such Lender or the Agent, as applicable, to identify the Borrower in accordance with the Patriot
Act. The Borrower shall provide, to the extent commercially reasonable, such information and take
such actions as are reasonably requested by the Agent or

60

 

any Lenders in order to assist the Agent and the Lenders in maintaining compliance with the
Patriot Act.

          SECTION 8.14. Waiver of Jury Trial. Each of the Borrower, the Agent and the Lenders
hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim
(whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the
Notes or the actions of the Agent or any Lender in the negotiation, administration, performance or
enforcement thereof.

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their
respective officers thereunto duly authorized, as of the date first above written.

Borrowing or from the application of the proceeds therefrom, that constitutes a Default.

EXHIBIT C — FORM OF

ASSIGNMENT AND ACCEPTANCE

          Reference is made to the Amended and Restated Credit Agreement dated as of July 11, 2007 (as
further amended or modified from time to time, the “Credit Agreement”) among Coventry
Health Care, Inc., a Delaware corporation (the “Borrower”), the Lenders (as defined in the
Credit Agreement), certain agents, and Citibank, N.A., as agent for the Lenders (the
“Agent”). Terms defined in the Credit Agreement are used herein with the same meaning.

          The “Assignor” and the “Assignee” referred to on Schedule I hereto agree as follows:

          1. The Assignor hereby sells and assigns to the Assignee, and the Assignee hereby purchases
and assumes from the Assignor, an interest in and to the Assignor’s rights and obligations under
the Credit Agreement as of the date hereof equal to the percentage interest specified on Schedule 1
hereto of all outstanding rights and obligations under the Credit Agreement Facility on Schedule 1
hereto together with participations in Letters of Credit held by the Assignor on the date hereof
excluding, however, the rights of the Assignor under Sections 2.11, 2.14 and 8.04 to the extent any
claim thereunder relates to an event arising prior to the Effective Date. After giving effect to
such sale and assignment, the Assignee’s Commitment and the amount of the Advances owing to the
Assignee will be as set forth on Schedule 1 hereto.

          2. The Assignor (i) represents and warrants that it is the legal and beneficial owner of the
interest being assigned by it hereunder and that such interest is free and clear of any adverse
claim; (ii) makes no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with the Credit Agreement or the
execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to be created under or
in connection with, the Credit Agreement or any other instrument or document furnished pursuant
thereto; (iii) makes no representation or warranty and assumes no responsibility with respect to
the financial condition of the Borrower or the performance or observance by the Borrower of any of
its obligations under the Credit Agreement or any other instrument or document furnished pursuant
thereto; and (iv) attaches the Notes[, if any] held by the Assignor [and requests that the Agent
exchange such Notes for new Notes payable to the order of [the Assignee in an amount equal to the
Commitments assumed by the Assignee pursuant hereto or new Notes payable to the order of the
Assignee in an amount equal to the Commitments assumed by the Assignee pursuant hereto and] the
Assignor in an amount equal to the Commitments retained by the Assignor under the Credit Agreement,
[respectively,] as specified on Schedule 1 hereto].

          3. The Assignee (i) confirms that it has received a copy of the Credit Agreement, together
with copies of the financial statements referred to in Section 4.01 thereof and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into this Assignment and Acceptance; (ii) agrees that it will, independently and without
reliance upon the Agent, the Assignor 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 the Credit Agreement; (iii) confirms

 

 

that it is an Eligible Assignee; (iv) appoints and authorizes the Agent to take such action as
agent on its behalf and to exercise such powers and discretion under the Credit Agreement as are
delegated to the Agent by the terms thereof, together with such powers and discretion as are
reasonably incidental thereto; (v) agrees that it will perform in accordance with their terms all
of the obligations that by the terms of the Credit Agreement are required to be performed by it as
a Lender; and (vi) attaches any U.S. Internal Revenue Service forms required under Section 2.14 of
the Credit Agreement.

          4. Following the execution of this Assignment and Acceptance, it will be delivered to the
Agent for acceptance and recording by the Agent. The effective date for this Assignment and
Acceptance (the “Effective Date”) shall be the date of recordation hereof by the Agent,
unless otherwise specified on Schedule 1 hereto.

          5. Upon such acceptance and recording by the Agent, as of the Effective Date, (i) the Assignee
shall be a party to the Credit Agreement and, to the extent provided in this Assignment and
Acceptance, have the rights and obligations of a Lender thereunder and (ii) the Assignor shall, to
the extent provided in this Assignment and Acceptance, relinquish its rights and be released from
its obligations under the Credit Agreement.

          6. Upon such acceptance and recording by the Agent, from and after the Effective Date, the
Agent shall make all payments under the Credit Agreement and the Notes in respect of the interest
assigned hereby (including, without limitation, all payments of principal, interest and facility
fees with respect thereto) to the Assignee. The Assignor and Assignee shall make all appropriate
adjustments in payments under the Credit Agreement and the Notes for periods prior to the Effective
Date directly between themselves.

          7. This Assignment and Acceptance shall be governed by, and construed in accordance with, the
laws of the State of New York.

          8. This Assignment and Acceptance may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so executed shall be deemed
to be an original and all of which taken together shall constitute one and the same agreement.
Delivery of an executed counterpart of Schedule 1 to this Assignment and Acceptance by telecopier
shall be effective as delivery of a manually executed counterpart of this Assignment and
Acceptance.

          IN WITNESS WHEREOF, the Assignor and the Assignee have caused Schedule 1 to this Assignment
and Acceptance to be executed by their officers thereunto duly authorized as of the date specified
thereon.

EXHIBIT D-1 — FORM OF

OPINION OF GENERAL COUNSEL

TO THE BORROWER

July 11, 2007

To the Lenders party to the Credit Agreement and

Citibank, N.A., as Agent

Ladies and Gentlemen:

          I am Senior Vice President and General Counsel of Coventry Health Care, Inc., a Delaware
corporation (the “Company”), and I am providing this opinion letter to you pursuant to
subsection 3.01(f)(iv) of that certain Amended and Restated Credit Agreement dated July 11, 2007,
among the Company, certain Lenders and Citibank, N.A., as Agent for the Lenders (the “Credit
Agreement”). Capitalized terms used but not otherwise defined herein have the same meanings as
in the Credit Agreement.

          In connection with this opinion, I have examined the Credit Agreement. I have also reviewed
such corporate documents and records of the Company and of the Subsidiaries of the Company (the
“Company Subsidiaries”), such certificates of public officials and such other matters as I
have deemed necessary or appropriate for purposes of this opinion letter. As to factual matters, I
have assumed the correctness of and relied upon statements and other representations of the Company
and the officers thereof set forth in the Credit Agreement and in certificates provided pursuant to
or in connection with the Credit Agreement or otherwise provided to me, and upon certificates of
public officials, and I have made no independent inquiries or investigations.

          In making such examination and in expressing my opinion, I have assumed, without investigation
or inquiry:

     (a) the authenticity of all documents submitted to me as originals, the genuineness of
all signatures, the conformity to authentic original documents of all documents submitted to
me as certified, conformed or photostatic copies and the legal capacity of all natural
persons, and

     (b) the enforceability of all agreements against parties thereto other than the Company
and the Company Subsidiaries, to the extent relevant to this opinion.

          Based on the foregoing, and subject to the assumptions, limitations and qualifications set
forth herein, it is my opinion that there is not, to my knowledge, any pending or threatened
action, suit or proceeding by or before any court or governmental agency, authority or body or any
arbitrator involving the Company or any of the Company Subsidiaries or its or their officers or
property that is of a character that would be required to be disclosed pursuant to Section 4.01(f)
of the Credit Agreement and that has not been so disclosed.

     The limitations inherent in the independent verification of factual matters and the character
of determinations involved in the process of preparing the Credit Agreement are such

 

 

that I have not verified and am not passing upon, and do not assume any responsibility for,
the accuracy, completeness or fairness of the statements contained in the Credit Agreement, except
as otherwise stated in the immediately preceding paragraph.

          The law covered by the opinions expressed herein is limited to the federal law of the United
States and the laws of the State of Pennsylvania.

          My opinion is rendered as of the date hereof and I assume no obligation to advise you of
changes in law or fact (or the effect thereof on the opinions expressed herein) that hereafter may
come to my attention.

          As used herein, “to my knowledge” and any similar phrase refers solely to my current, actual
knowledge.

          The opinions rendered herein are solely for the benefit of the Agent, the Lenders and their
respective successors and assigns in connection with the transactions that are the subject of the
Credit Agreement, and this opinion letter may not be delivered to or relied upon by any other
person nor quoted nor reproduced in any report or other document without my prior written consent;
provided, however, that a copy of this opinion letter may be furnished to your regulators,
accountants, attorneys and other professional advisors for the purpose of confirming its existence,
and this opinion letter may be disclosed in connection with any legal or regulatory proceeding
relating to the subject matter hereof.

Very truly yours,

Thomas C. Zielinski

Senior Vice President and General Counsel

 

 

EXHIBIT D-2 — FORM OF

OPINION OF BASS, BERRY & SIMS PLC

July 11, 2007

To the Lenders party to the Credit Agreement, and

Citibank, N.A., as Agent

Ladies and Gentlemen:

          We have acted as counsel to Coventry Health Care, Inc., a Delaware corporation (the
“Company”), in connection with the transactions that are the subject of that certain
Amended and Restated Credit Agreement dated July 11, 2007, among the Company, certain Lenders and
Citibank, N.A., as Agent for the Lenders (the “Credit Agreement”). This opinion letter is
provided to you at the request of the Company pursuant to subsection 3.01(f)(iv) of the Credit
Agreement. Capitalized terms used but not otherwise defined herein have the same meanings as in
the Credit Agreement.

          We have examined the Credit Agreement and the Notes executed and delivered by the Company on
the date hereof (collectively the “Loan Documents”; hereinafter, “Notes” shall mean
and refer to the Notes executed and delivered by the Company on the date hereof). We have also
reviewed such corporate records of the Company, such certificates of public officials and such
other matters regarding the Company as we have deemed necessary or appropriate for purposes of this
opinion letter. As to factual matters, we have assumed the correctness of and relied upon
statements and other representations of the Company and the officers thereof set forth in the
Credit Agreement and in certificates provided pursuant to or in connection with the Credit
Agreement or otherwise provided to us, and upon certificates of public officials, and we have made
no independent inquiries or investigations. For purposes of the opinions on the existence and good
standing of the Company, we have relied solely upon a certificate of existence from the Delaware
Secretary of State dated July ___, 2007.

          In making such examination and in expressing our opinions, we have assumed, without
investigation or inquiry:

     (a) the due organization and existence of all parties to the Loan Documents, except to
the extent that we express an opinion in Paragraph 1 below regarding the incorporation and
existence of the Company,

     (b) the due authorization, execution and delivery of the Loan Documents by all parties
thereto other than the Company,

     (c) that all parties to the Loan Documents have the legal right, power and authority to
enter into the Loan Documents and to consummate the transactions contemplated thereby,
except to the extent that we express an opinion in Paragraph 1 below regarding the corporate
power and corporate authority of the Company, and

 

 

     (d) that all signatures on any executed documents furnished to us are genuine, all
original documents submitted to us are authentic originals and all certified or other
reproductions of documents submitted to us conform to the original documents.

          Based upon the foregoing and subject to the assumptions, limitations and qualifications herein
set forth, we are of the opinion that:

          1. The Company is a duly incorporated and validly existing Delaware corporation, in good
standing under the laws of Delaware. The Company has the necessary corporate power and corporate
authority to execute and deliver the Credit Agreement and the Notes and to enter into and perform
its obligations thereunder. The execution and delivery of the Credit Agreement and the Notes and
the performance and observance of the provisions thereof have been properly authorized by all
necessary corporate actions on the part of the Company.

          2. The Credit Agreement has been properly executed by the Company and, as executed and
delivered, is a valid and binding obligation of the Company and is enforceable against the Company
in accordance with its terms. The Notes have been properly executed by the Company and, as
executed and delivered, are valid and binding obligations of the Company and are enforceable
against the Company in accordance with their respective terms.

          3. The execution and delivery by the Company of the Credit Agreement and the Notes, the
consummation of the financing transaction that is the subject thereof and the borrowings by the
Company in accordance with the Credit Agreement (a) will not violate the certificate of
incorporation or bylaws of the Company, (b) are not prohibited by, and will not subject the
Company, the Agent or any Lender to any fine, penalty or similar sanction under, any federal,
Tennessee or Delaware statute or regulation (including but not limited to Regulation X of the Board
of Governors of the Federal Reserve System) or, to our knowledge, any order of any court,
arbitrator or regulatory authority having jurisdiction over the Company, and (c) will not
constitute a breach of or a default under, or result in the imposition of a Lien on any properties
of the Company under, any of the Indentures identified on Annex 1 hereto. Please note,
however, that the incurrence of indebtedness under the Credit Agreement and the Notes in excess of
the unused amounts permitted by Subsections 4.08(2)(b), (k) and (m) of the 2005 Indentures would
require compliance with Subsection 4.08(1) of the 2005 Indentures.

          4. No authorization, consent, approval or other action by or filing with any federal,
Tennessee or Delaware governmental authority is required for the execution and delivery by the
Company of the Credit Agreement and the Notes, the consummation of the financing transaction that
is the subject thereof, borrowings by the Company thereunder or the performance by the Company of
its payment obligations thereunder.

          We express no opinion as to the enforceability of the choice of law provisions contained in
the Credit Agreement under the laws of New York or Tennessee, nor, assuming such provisions would
be enforceable under the choice-of-law principles of New York and Tennessee, do we state any
opinion as to the enforceability of the Credit Agreement or the Notes under the internal laws of
New York. Notwithstanding the foregoing, you have requested us to examine the Credit Agreement and
the Notes and provide you with the opinions set forth herein assuming, solely for purposes of such
opinions, that the internal laws of Tennessee would govern

 

 

them. If the Credit Agreement and the Notes were to be governed by the internal laws of
Tennessee, our opinions would be as set forth herein. We note that if a court of competent
jurisdiction determines one or more of the Credit Agreement and the Notes to be unenforceable under
the laws of New York, then such document(s) may not be enforced by Tennessee courts under
applicable Tennessee conflict of law principles.

          The opinions expressed herein are limited to the laws of Tennessee, the Delaware General
Corporation Law and the federal laws of the United States of America.

          The opinions expressed herein are qualified as follows:

     (a) The validity, binding nature and enforceability of any liability, obligation,
instrument, document or agreement are subject to (i) applicable bankruptcy, reorganization,
insolvency, moratorium, fraudulent conveyance, fraudulent transfer and similar federal and
state laws affecting the rights and remedies of creditors generally, and (ii) general
principles of equity, whether applied in a proceeding at law or in equity, which may, among
other things, limit the ability of the Agent or the Lenders to accelerate the maturity of
the Company’s obligations under the Credit Agreement and the Notes on the basis of an
immaterial breach of a provision of the Loan Documents, or limit the availability of
equitable remedies (including but not limited to the remedy of specific performance).

     (b) We express no opinion with respect to the effect of any provision of the Loan
Documents insofar as it provides that any Person purchasing a participation from a Lender or
other Person may exercise set-off or similar rights with respect to such participation or
that any Lender or other Person may exercise set-off or similar rights other than in
accordance with applicable law.

     (c) We express no opinion with respect to the effect of any provision of the Loan
Documents imposing penalties or forfeitures.

     (d) We express no opinion with respect to the enforceability of any provision of any of
the Loan Documents to the extent that such provision constitutes a waiver of illegality as a
defense to performance of contract obligations.

     (e) We express no opinion with respect to the effect of any provision of the Loan
Documents relating to indemnification or exculpation in connection with violations of any
securities laws or relating to indemnification, contribution or exculpation in connection
with willful, reckless or criminal acts or gross negligence of the indemnified or exculpated
Person or the Person receiving contribution.

     (f) We express no opinion with respect to compliance or the effects of noncompliance
with laws governing usury, interest or loan charges.

     (g) We express no opinion as to the authorization of (i) any Commitment Increase, (ii)
any instrument or agreement between or among the Company, the Agent and any of the Lenders
to effectuate a Commitment Increase or (iii) any Borrowing or

 

 

other extension of credit under the Credit Agreement that requires utilization of a
Commitment Increase.

     (h) We express no opinion with respect to compliance or the effects of noncompliance
with financial covenants or ratios or with respect to any other matter that would require us
to perform a mathematical calculation or to make a financial or accounting determination.

          Our opinion is rendered as of the date hereof, and we assume no obligation to advise you of
changes in law or fact (or the effect thereof on the opinions expressed herein) that hereafter may
come to our attention.

          As used herein, “knowledge”, “known to us”, “to our knowledge” and any similar expression
refer solely to the current, actual knowledge, acquired during the course of our representation of
the Company, of those attorneys in this firm who have rendered legal services in connection with
such representation.

          The opinions rendered herein are solely for the benefit of the Agent, the Lenders and their
respective successors and assigns in connection with the transactions that are the subject of the
Loan Documents, and this opinion letter may not be delivered to or relied upon by any other person
nor quoted nor reproduced in any report or other document without our prior written consent;
provided, however, that a copy of this opinion letter may be furnished to your regulators,
accountants, attorneys and other professional advisors for the purpose of confirming its existence,
and this opinion letter may be disclosed in connection with any legal or regulatory proceeding
relating to the subject matter hereof.

Very truly yours,
