being understood that no Lender shall be responsible for any default by any other Lender in that
other Lender’s obligation to make a Loan requested hereunder nor shall the Commitment of any Lender
to make the Loan requested be increased or decreased as a result of a default by any other Lender
in that other Lender’s obligation to make a Loan requested hereunder. Promptly after receipt by
Administrative Agent of a Notice of Borrowing pursuant to subsection 2.1B (or telephonic notice in
lieu thereof), Administrative Agent shall notify each Lender of the proposed borrowing. Each
Lender shall make the amount of its Loan available to Administrative Agent not later than 12:00
Noon (New York City time) on the Funding Date in same day funds in Dollars, at the Funding and
Payment Office. Upon satisfaction or waiver of the conditions precedent specified in subsection
4.2, Administrative Agent shall make the proceeds of the Loans available to Company on the Funding
Date by causing an amount of same day funds in Dollars equal to the proceeds of all such Loans
received by Administrative Agent from Lenders to be credited to the account of Company.

28

 

          Unless Administrative Agent shall have been notified by any Lender prior to the Funding Date
that such Lender does not intend to make available to Administrative Agent the amount of such
Lender’s Loan requested on the Funding Date, Administrative Agent may assume that such Lender has
made such amount available to Administrative Agent on the Funding Date and Administrative Agent
may, in its sole discretion, but shall not be obligated to, make available to Company a
corresponding amount on the Funding Date. If such corresponding amount is not in fact made
available to Administrative Agent by such Lender, Administrative Agent shall be entitled to recover
such corresponding amount on demand from such Lender together with interest thereon, for each day
from the Funding Date until the date such amount is paid to Administrative Agent, at the customary
rate set by Administrative Agent for the correction of errors among banks for three Business Days
and thereafter at the Alternate Base Rate. If such Lender does not pay such corresponding amount
within three Business Days after such amount should have been made available, Administrative Agent
shall promptly notify Company and Company shall immediately pay such corresponding amount to
Administrative Agent together with interest thereon, for each day from the Funding Date until the
date such amount is paid to Administrative Agent, at the rate payable under this Agreement for
Alternate Base Rate Loans. Nothing in this subsection 2.1C shall be deemed to relieve any Lender
from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Company
may have against any Lender as a result of any default by such Lender hereunder.

          D. The Register.

               (i) Administrative Agent, acting solely for this purpose as a non-fiduciary agent
of Company, shall maintain, at its address referred to in subsection 10.8, a register for
the recordation of the names and addresses of Lenders and the Commitments and Loans of each
Lender from time to time (the “Register”). The Register shall be available for inspection
by Company or any Lender at any reasonable time and from time to time upon reasonable prior
notice.

               (ii) Administrative Agent shall record in the Register the Commitment and the
Loans from time to time of each Lender and each repayment or prepayment in respect of the
principal amount of the Loans of each Lender. Any such recordation shall be conclusive and
binding on Company and each Lender, absent manifest error; provided that failure to make
any such recordation, or any error in such recordation, shall not affect any Lender’s
Commitments or Company’s Obligations in respect of any applicable Loans.

               (iii) Each Lender shall record on its internal records (including any Notes held
by such Lender) each Loan made by it and each payment in respect thereof. Any such
recordation shall be conclusive and binding on Company, absent manifest error; provided
that failure to make any such recordation, or any error in such recordation, shall not
affect any Lender’s Commitments or Company’s Obligations in respect of any applicable
Loans; and provided, further, that in the event of any

29

 

inconsistency between the Register and any Lender’s records, the recordations in the
Register shall govern.

               (iv) Company, Administrative Agent and Lenders shall deem and treat the Persons
listed as Lenders in the Register as the holders and owners of the corresponding
Commitments and Loans listed therein for all purposes hereof, and no assignment or transfer
of any such Commitment or Loan shall be effective, in each case unless and until an
Assignment Agreement effecting the assignment or transfer thereof shall have been accepted
by Administrative Agent and recorded in the Register as provided in subsection 10.1B(ii).
Prior to such recordation, all amounts owed with respect to the applicable Commitment or
Loan shall be owed to the Lender listed in the Register as the owner thereof, and any
request, authority or consent of any Person who, at the time of making such request or
giving such authority or consent, is listed in the Register as a Lender shall be conclusive
and binding on any subsequent holder, assignee or transferee of the corresponding
Commitments or Loans.

               (v) Company hereby designates Credit Suisse to serve as Company’s agent solely for
purposes of maintaining the Register as provided in this subsection 2.1D, and Company
hereby agrees that, to the extent Credit Suisse serves in such capacity, Credit Suisse and
its officers, directors, employees, agents and affiliates shall constitute Indemnitees for
all purposes under subsection 10.3.

          E. Notes. At the request of any Lender, Company shall execute and deliver to that Lender
(or to Administrative Agent for that Lender) a Note substantially in the form of Exhibit IV annexed
hereto to evidence that Lender’s Loan, in the principal amount of that Lender’s Loan and with other
appropriate insertions. In the event a Lender requests such Note at least 3 Business Days prior to
the Funding Date, Company shall execute and deliver such Note on such date.

          2.2 Interest on the Loans

          A. Rate of Interest. Subject to the provisions of subsections 2.6 and 2.7, the Loans
shall bear interest on the unpaid principal amount thereof from the Funding Date through maturity
(whether by acceleration or otherwise) at a rate determined by reference to the Alternate Base Rate
or the Adjusted Eurodollar Rate. The applicable basis for determining the rate of interest with
respect to any Loans shall be selected by Company initially at the time a Notice of Borrowing is
given with respect to the Loans pursuant to subsection 2.1B, and the basis for determining the
interest rate with respect to any Loans may be changed from time to time pursuant to subsection
2.2D. If on any day Loans are outstanding with respect to which notice has not been delivered to
Administrative Agent in accordance with the terms of this Agreement specifying the applicable basis
for determining the rate of interest, then for that day such Loans shall bear interest determined
by reference to the Alternate Base Rate. Subject to the provisions of subsections 2.2E and 2.7,
the Loans shall bear interest through maturity as follows:

30

 

               (i) if an Alternate Base Rate Loan, then at the sum of the Alternate Base Rate and
the applicable Alternate Base Rate Margin set forth in the table below opposite the
Consolidated Leverage Ratio for the four-Fiscal Quarter period ending on the date for which
the applicable Compliance Certificate has been delivered pursuant to subsection 6.1(iii):

CONSOLIDATED LEVERAGE RATIO

	 	 	 	 	 
	 	 	APPLICABLE
	 	 	ALTERNATE BASE
	 	 	RATE MARGIN
	 	 	(PER ANNUM)
	Level 1 Greater than or equal to 2.0x
	 	 	0.75	%
	Level 2 Greater than or equal to 1.0x but less than 2.0x
	 	 	0.50	%
	Level 3 Less than 1.0x
	 	 	0.25	%

provided, that the Alternate Base Rate Margin will increase by 0.25% on the
90th day after the Funding Date and by an additional 0.25% every 90 days
thereafter.

               (ii) if a Eurodollar Rate Loan, then at the sum of the Adjusted Eurodollar Rate
and the applicable Eurodollar Rate Margin set forth in the table below opposite the
Consolidated Leverage Ratio for the four-Fiscal Quarter period ending on the date for which
the applicable Compliance Certificate has been delivered pursuant to subsection 6.1(iii):

CONSOLIDATED LEVERAGE RATIO

	 	 	 	 	 
	 	 	APPLICABLE
	 	 	EURODOLLAR
	 	 	RATE MARGIN
	 	 	(PER ANNUM)
	Level 1 Greater than or equal to 2.0x
	 	 	1.75	%
	Level 2 Greater than or equal to 1.0x but less than 2.0x
	 	 	1.50	%
	Level 3 Less than 1.0x
	 	 	1.25	%

provided, that the Eurodollar Rate Margin will increase by 0.25% on the 90th day
after the Funding Date and by an additional 0.25% every 90 days thereafter.

          Upon delivery of the Compliance Certificate by Company to Administrative Agent pursuant to
subsection 6.1(iii), the applicable Alternate Base Rate Margin and Eurodollar Rate Margin shall
automatically be adjusted in accordance with such Compliance Certificate, such adjustment to become
effective on the next succeeding Business Day following receipt by Administrative Agent of such
Compliance Certificate; provided, that if at any time a Compliance Certificate is not delivered at
the time required pursuant to subsection 6.1(iii), from the time such Compliance Certificate was
required to be delivered until delivery of such Compliance Certificate, such applicable Alternate
Base Rate Margin and Eurodollar Rate Margin shall be the maximum percentage amount until such
Compliance Certificate is delivered.

31

 

          B. Interest Periods. In connection with each Eurodollar Rate Loan, Company may, pursuant
to the applicable Notice of Borrowing or Notice of Conversion/Continuation, as the case may be,
select an interest period (each an “Interest Period”) to be applicable to such Loan, which Interest
Period shall be, at Company’s option, a one, two or three month period; provided that:

               (i) the initial Interest Period for any Eurodollar Rate Loan shall commence on the
Funding Date in respect of such Loan, in the case of Loans being initially made as
Eurodollar Rate Loans, or on the date specified in the applicable Notice of
Conversion/Continuation, in the case of Loans being converted to Eurodollar Rate Loans;

               (ii) in the case of immediately successive Interest Periods applicable to a Eurodollar
Rate Loan continued as such pursuant to a Notice of Conversion/Continuation, each
successive Interest Period shall commence on the day on which the next preceding Interest
Period expires;

               (iii) if an Interest Period would otherwise expire on a day that is not a Business
Day, such Interest Period shall expire on the next succeeding Business Day; provided that,
if any Interest Period would otherwise expire on a day that is not a Business Day but is a
day of the month after which no further Business Day occurs in such month, such Interest
Period shall expire on the next preceding Business Day;

               (iv) any Interest Period that begins on the last Business Day of a calendar month (or
on a day for which there is no numerically corresponding day in the calendar month at the
end of such Interest Period) shall, subject to clause (v) of this subsection 2.2B, end on
the last Business Day of a calendar month;

               (v) no Interest Period with respect to any portion of the Loans shall extend beyond
the Original Maturity Date; provided that to the extent that the maturity of any portion of
the Loans is extended to the Extended Maturity Date in accordance with subsection 2.4A(ii),
then Interest Periods with respect to the portion of the Loans so extended may extend
beyond the Original Maturity Date (but not beyond the Extended Maturity Date);

               (vi) there shall be no more than four Interest Periods outstanding at any time; and

               (vii) in the event Company fails to specify an Interest Period for any Eurodollar Rate
Loan in the applicable Notice of Borrowing or Notice of

32

 

Conversion/Continuation, Company shall be deemed to have selected an Interest Period
of one month.

          C. Interest Payments. Subject to the provisions of subsection 2.2E, interest on each Loan
shall be payable in arrears on and to each Interest Payment Date applicable to that Loan, upon any
prepayment of that Loan (to the extent accrued on the amount being prepaid) and at maturity
(including final maturity).

          D. Conversion or Continuation. Subject to the provisions of subsection 2.6, Company shall
have the option (i) to convert at any time all or any part of its outstanding Loans equal to
$5,000,000 and integral multiples of $1,000,000 in excess of that amount from Loans bearing
interest at a rate determined by reference to one basis to Loans bearing interest at a rate
determined by reference to an alternative basis or (ii) upon the expiration of any Interest Period
applicable to a Eurodollar Rate Loan, to continue all or any portion of such Loan equal to
$5,000,000 and integral multiples of $1,000,000 in excess of that amount as a Eurodollar Rate Loan;
provided, however, that a Eurodollar Rate Loan may only be converted into a Alternate Base Rate
Loan on the expiration date of an Interest Period applicable thereto.

          Company shall deliver a Notice of Conversion/Continuation to Administrative Agent no later
than 12:00 Noon (New York City time) at least one Business Day in advance of the proposed
conversion date (in the case of a conversion to an Alternate Base Rate Loan) and at least three
Eurodollar Business Days in advance of the proposed conversion/continuation date (in the case of a
conversion to, or a continuation of, a Eurodollar Rate Loan). A Notice of Conversion/Continuation
shall specify (i) the proposed conversion/continuation date (which shall be a Business Day), (ii)
the amount and type of the Loan to be converted/continued, (iii) the nature of the proposed
conversion/continuation, (iv) in the case of a conversion to, or a continuation of, a Eurodollar
Rate Loan, the requested Interest Period, and (v) in the case of a conversion to, or a continuation
of, a Eurodollar Rate Loan, that no Potential Event of Default or Event of Default has occurred and
is continuing. In lieu of delivering the above-described Notice of Conversion/Continuation,
Company may give Administrative Agent telephonic notice by the required time of any proposed
conversion/continuation under this subsection 2.2D; provided that such notice shall be promptly
confirmed in writing by delivery of a Notice of Conversion/Continuation to Administrative Agent on
or before the proposed conversion/continuation date. Upon receipt of written or telephonic notice
of any proposed conversion/continuation under this subsection 2.2D, Administrative Agent shall
promptly notify each Lender.

          Neither Administrative Agent nor any Lender shall incur any liability to Company in acting
upon any telephonic notice referred to above that Administrative Agent believes in good faith to
have been given by a duly authorized officer or other person authorized to act on behalf of Company
or for otherwise acting in good faith under this subsection 2.2D, and upon conversion or
continuation of the applicable basis for determining the interest rate with respect to any Loans in
accordance with this Agreement pursuant to any such telephonic notice Company shall have effected a
conversion or continuation, as the case may be, hereunder.

33

 

          Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice of
Conversion/Continuation for conversion to, or continuation of, a Eurodollar Rate Loan (or
telephonic notice in lieu thereof) shall be irrevocable and Company shall be bound to effect a
conversion or continuation in accordance therewith.

          E. Default Rate. In the event that the outstanding principal amount of any Loan, any interest
or any fees or other amounts due and payable hereunder are not paid when due, such overdue amounts
shall thereafter bear interest (including post-petition interest in any proceeding under the
Bankruptcy Code or other applicable bankruptcy laws) payable upon demand at a rate that is 2% per
annum in excess of the interest rate otherwise payable under this Agreement with respect to the
applicable Loans (or, in the case of any such fees and other amounts, at a rate which is 2% per
annum, in excess of the interest rate otherwise payable under this Agreement for Alternate Base
Rate Loans); provided that, in the case of Eurodollar Rate Loans, upon the expiration of the
Interest Period in effect at the time any such increase in interest rate is effective such
Eurodollar Rate Loans shall thereupon become Alternate Base Rate Loans and shall thereafter bear
interest payable upon demand at a rate which is 2% per annum in excess of the interest rate
otherwise payable under this Agreement for Alternate Base Rate Loans. Payment or acceptance of the
increased rates of interest provided for in this subsection 2.2E is not a permitted alternative to
timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or
limit any rights or remedies of Administrative Agent or any Lender.

          F. Computation of Interest. Interest on the Loans shall be computed on the basis of (i) in
the case of Eurodollar Rate Loans a 360-day year or (ii) in the case of Alternate Base Rate Loans,
a 365 or 366-day year, unless the interest rate on such Alternate Base Rate Loans is based on the
Federal Funds Rate or the Adjusted Eurodollar Rate, in which case the calculation will be on the
basis of a 360-day year, in each case for the actual number of days elapsed in the period during
which it accrues. In computing interest on any Loan, the date of the making of such Loan or the
first day of an Interest Period applicable to such Loan or, with respect to an Alternate Base Rate
Loan being converted from a Eurodollar Rate Loan the date of conversion of such Eurodollar Rate
Loan to such Alternate Base Rate Loan, as the case may be, shall be included, and the date of
payment of such Loan or the expiration date of an Interest Period applicable to such Loan or, with
respect to an Alternate Base Rate Loan being converted to a Eurodollar Rate Loan, the date of
conversion of such Base Rate Loan to such Eurodollar Rate Loan, as the case may be, shall be
excluded; provided that if a Loan is repaid on the same day on which it is made, one day’s interest
shall be paid on that Loan.

          2.3 Fees

          A. Ticking Fees. Company agrees to pay to Administrative Agent, for distribution to each
Lender (other than a Defaulting Lender, for so long as such Lender is a Defaulting Lender) in
proportion to that Lender’s Pro Rata Share, ticking fees for the period from and including the
Closing Date to but excluding the Funding Date or earlier termination in full of the Commitments
equal to the daily aggregate amount of the Commitments during such

34

 

period multiplied by a percentage per annum equal to (i) for the period commencing on and
including the Closing Date and ending on and including October 18, 2011, 0.15%, and (ii)
thereafter, 0.20%, such ticking fees to be calculated on the basis of a 360-day year and the actual
number of days elapsed and to be payable on the earlier of (x) the Funding Date and (y) upon the
termination of the Commitments.

          B. Duration Fees. Company agrees to pay to Administrative Agent, for the account of and for
distribution to each Lender in proportion to that Lender’s Pro Rata Share (i) on the
90th day after the Funding Date, a fee equal to 0.50% of the aggregate principal amount
of the Loans of such Lender outstanding on such date, due and payable on the Business Day following
such 90th day, (ii) on the 180th day after the Funding Date, a fee equal to
0.75% of the aggregate principal amount of the Loans of such Lender outstanding on such date, due
and payable on the Business Day following such 180th day, and (iii) on the
270th day after the Funding Date, a fee equal to 1.00% of the aggregate principal amount
of the Loans of such Lender outstanding on such date, due and payable on the Business Day following
such 270th day.

          C. Funding Fee. Company agrees to pay to Administrative Agent, for the account of and for
distribution to each Lender in proportion to that Lender’s Pro Rata Share, a fee equal to 0.625% of
the aggregate principal amount of the Loans of such Lender funded on the Funding Date, due and
payable on the Funding Date.

          D. Other Fees. Company agrees to pay to an Agent such other fees in the amounts and at the
times separately agreed upon between Company and such Agent and the Joint Lead Arrangers.

          2.4 Repayments, Prepayments and Reductions Commitments; General Provisions Regarding Payments

          A. Maturity Date; Prepayments and Unscheduled Reductions in Commitments.

               (i) Maturity. The Loans shall mature on (x) with respect to Loans the maturity of
which have been extended in accordance with subsection 2.4A(ii), the Extended Maturity
Date, and (y) otherwise, the Original Maturity Date and, in either case, any Loans then
outstanding (together with accrued interest thereon and fees in respect thereof) shall be
due and payable on such date.

               (ii) Extension. Company may request, by delivering to Administrative Agent a Notice
of Extension (which notice Administrative Agent shall promptly forward to each of the
Lenders), on a date (the “Election Date”) occurring no more than 60 nor fewer than 30 days
prior to the Original Maturity Date, that the maturity

35

 

of up to 50% of the Loans outstanding on the Election Date be extended (the
“Extension”) to a date (the “Extended Maturity Date) that is not later than the date three
months following the Original Maturity Date and, if Company so requests, then as of the
Original Maturity Date, the maturity of such Loans (allocated ratably among the Lenders)
shall be extended until the Extended Maturity Date so long as the following conditions
shall be satisfied as of the Original Maturity Date:

               (a) receipt by Administrative Agent for the account of the Lenders of an extension fee
equal to 1.25% of the aggregate principal amount of the Loans subject to such extension, as
well as all other fees, costs and expenses payable by Company under and in respect of this
Agreement on or prior to the Original Maturity Date for the account of Administrative Agent
or any of the Lenders;

               (b) the representations and warranties contained herein and in the other Loan
Documents shall be true, correct and complete in all material respects to the same extent
as though made on and as of the Original Maturity Date, except to the extent such
representations and warranties specifically relate to an earlier date, in which case such
representations and warranties shall have been true, correct and complete in all material
respects on and as of such earlier date;

               (c) no event shall have occurred and be continuing or would result from the Extension
that would constitute an Event of Default or a Potential Event of Default; and

               (d) Company shall have delivered to Administrative Agent an Officer’s Certificate
dated the Original Maturity Date confirming compliance with the conditions set forth in
clauses (b) and (c) of this subsection 2.4A(ii).

               (iii) Voluntary Prepayments. Company may, upon not less than one Business Day’s prior
written or telephonic notice, in the case of Alternate Base Rate Loans, and three Business
Days’ prior written or telephonic notice, in the case of Eurodollar Rate Loans, in each
case given to Administrative Agent by 12:00 Noon (New York City time) on the date required
and, if given by telephone, promptly confirmed in writing to Administrative Agent (which
written or telephonic notice Administrative Agent will promptly transmit by telefacsimile
or telephone to each Lender), at any time and from time to time prepay any Loans on any
Business Day in whole or in part in an aggregate minimum amount of $10,000,000 and integral
multiples of $1,000,000 without premium or penalty; provided, however, that Company shall
pay any amounts payable pursuant to subsection 2.6D in connection with any such prepayment
other than at the expiration of an Interest Period. Notice of prepayment having been given
as aforesaid, the principal amount of the Loans specified in such notice shall become due
and payable on the prepayment date specified therein.

36

 

               (iv) Voluntary Termination or Reduction of Commitments. Company may, upon not less
than one Business Day’s prior written or telephonic notice confirmed in writing to
Administrative Agent (which written or telephonic notice Administrative Agent will promptly
transmit by telefacsimile or telephonic notice confirmed in writing to each Lender), at any
time and from time to time terminate in whole or permanently reduce in part, without
premium or penalty, the Commitments; provided that any such partial reduction of the
Commitments shall be in an aggregate minimum amount of $10,000,000 and integral multiples
of $1,000,000 in excess of that amount. Company’s notice to Administrative Agent shall
designate the date (which shall be a Business Day) of such termination or reduction and the
amount of any partial reduction, and such termination or reduction of the Commitments shall
be effective on the date specified in Company’s notice.

               (v) Pre-Funding Date Syndicated Term Loan Commitments. On the effective date of any
Pre-Funding Date Syndicated Term Loan Commitments, the Commitments shall be automatically
reduced by an amount equal to the aggregate principal amount of such Pre-Funding Date
Syndicated Term Loan Commitments.

               (vi) Mandatory Reductions of Commitments. On the date of any receipt by Company or
any of its Subsidiaries after the Closing Date but on or prior to the Funding Date of Net
Cash Proceeds in respect of any Prepayment/Reduction Event (other than an Asset Sale), the
Commitments shall be automatically reduced by an amount equal to the amount of such Net
Cash Proceeds.

               (vii) Mandatory Prepayments. Within five Business Days after the receipt by Company
or any of its Subsidiaries of Net Cash Proceeds in respect of any Prepayment/Reduction
Event occurring after the Funding Date, Company shall prepay the Loans in an aggregate
amount equal to 100% of such Net Cash Proceeds without premium or penalty; provided,
however, that Company shall pay any amounts payable pursuant to subsection 2.6D in
connection with any such prepayment other than at the expiration of an Interest Period.

               (viii) Application of Prepayments. Any prepayment of Loans shall be applied first to
Alternate Base Rate Loans to the full extent thereof before application to Eurodollar Rate
Loans, in each case in a manner which minimizes the amount of any payments required to be
made by Company pursuant to subsection 2.6D.

               (ix) Effect of Termination or Reduction. Any termination or reduction of the
Commitments shall be permanent. Each reduction of the Commitments shall be made ratably
among the Lenders in accordance with their respective Pro Rata Shares; provided, however,
that any reduction in the Commitments made pursuant to subsection 2.4A(v) shall be applied
first, ratably, to the Commitments of Credit Suisse and Citibank, N.A. (or their respective
Affiliates), until an aggregate of $4,000,000,000

37

 

of their Commitments shall have been so reduced pursuant to such subsection, and then
ratably among the Lenders (including Credit Suisse and Citibank, N.A. and their respective
Affiliates) in accordance with their respective Pro Rata Shares.

          B. General Provisions Regarding Payments.

               (i) Manner and Time of Payment. All payments by Company of principal, interest, fees
and other Obligations hereunder and under the Notes shall be made in Dollars in same day
funds, without defense, setoff or counterclaim, free of any restriction or condition, and
delivered to Administrative Agent not later than 12:00 Noon (New York City time) on the
date due at the Funding and Payment Office for the account of Lenders; funds received by
Administrative Agent after that time on such due date shall be deemed to have been paid by
Company on the next succeeding Business Day.

               (ii) Application of Payments to Principal and Interest. Except as provided in
subsection 2.2C, all payments in respect of the principal amount of any Loan shall include
payment of accrued interest on the principal amount being repaid or prepaid, and all such
payments (and, in any event, any payments in respect of any Loan on a date when interest is
due and payable with respect to such Loan) shall be applied to the payment of interest
before application to principal.

               (iii) Apportionment of Payments. Except as provided above with respect to the ticking
fees of Defaulting Lenders, aggregate principal, interest and fee payments in respect of
Loans and Commitments shall be apportioned proportionately to Lenders’ respective Pro Rata
Shares. Administrative Agent shall promptly distribute to each Lender, at its primary
address set forth below its name on the appropriate signature page hereof or at such other
address as such Lender may request, its Pro Rata Share of all such payments received by
Administrative Agent when received by Administrative Agent and the fees of such Lender when
received by Administrative Agent pursuant to subsection 2.3. Notwithstanding the foregoing
provisions of this subsection 2.4B(iii), if, pursuant to the provisions of subsection 2.6C,
any Notice of Conversion/Continuation is withdrawn as to any Affected Lender or if any
Affected Lender makes Alternate Base Rate Loans in lieu of its Pro Rata Share of any
Eurodollar Rate Loans, Administrative Agent shall give effect thereto in apportioning
payments received thereafter.

               (iv) Payments on Business Days. Except as otherwise expressly provided herein,
whenever any payment to be made hereunder shall be stated to be due on a day that is not a
Business Day, such payment shall be made on the next succeeding Business Day and such
extension of time shall be included in the computation of the payment of interest
hereunder.

38

 

               (v) Notation of Payment. Each Lender agrees that before disposing of any Note held by
it, or any part thereof (other than by granting participations therein), that Lender will
make a notation thereon of all Loans evidenced by that Note and all principal payments
previously made thereon and of the date to which interest thereon has been paid; provided
that the failure to make (or any error in the making of) a notation of any Loan made under
such Note shall not limit or otherwise affect the obligations of Company hereunder or under
such Note with respect to any Loan or any payments of principal or interest on such Note.

          C. Payments Under Subsidiary Guaranty. All payments received by Administrative Agent under
the Subsidiary Guaranty shall be applied promptly from time to time by Administrative Agent in the
following order of priority:

               (i) to the payment of the costs and expenses of any collection or other realization
under the Subsidiary Guaranty, including reasonable compensation to Administrative Agent
and its agents and counsel, and all expenses, liabilities and advances made or incurred by
Administrative Agent in connection therewith, all in accordance with the terms of this
Agreement and the Subsidiary Guaranty;

               (ii) thereafter, to the extent of any excess such payments, to the payment of all
other Guarantied Obligations (as defined in the Subsidiary Guaranty) for the ratable
benefit of the holders thereof; and

               (iii) thereafter, to the extent of any excess such payments, to the payment to the
applicable Subsidiary Guarantor or to whosoever may be lawfully entitled to receive the
same or as a court of competent jurisdiction may direct.

          2.5 Use of Proceeds

          A. Loans. The proceeds of the Loans made on the Funding Date shall be used solely to finance,
in part, the Acquisition and the Refinancing and to pay fees and expenses in connection with the
Transactions.

          B. Margin Regulations. No portion of the proceeds of any borrowing under this Agreement shall
be used by Company or any of its Subsidiaries in any manner that might cause the borrowing or the
application of such proceeds to violate Regulation U, Regulation T or Regulation X of the Board of
Governors of the Federal Reserve System or any other regulation of such Board or to violate the
Exchange Act, in each case as in effect on the date or dates of such borrowing and such use of
proceeds.

          2.6 Special Provisions Governing Eurodollar Rate Loans

39

 

          Notwithstanding any other provision of this Agreement to the contrary, the following
provisions shall govern with respect to Eurodollar Rate Loans as to the matters covered:

          A. Determination of Applicable Interest Rate. As soon as practicable after 11:00 A.M. (London
time) on each Interest Rate Determination Date, Administrative Agent shall determine (which
determination shall, absent manifest error, be final, conclusive and binding upon all parties) the
interest rate that shall apply to the Eurodollar Rate Loans for which an interest rate is then
being determined for the applicable Interest Period and shall promptly give notice thereof (in
writing or by telephone confirmed in writing) to Company and each Lender.

          B. Inability to Determine Applicable Interest Rate. In the event that Administrative Agent
shall have determined (which determination shall be final and conclusive and binding upon all
parties hereto), on any Interest Rate Determination Date with respect to any Eurodollar Rate Loans,
that by reason of circumstances affecting the interbank Eurodollar market adequate and fair means
do not exist for ascertaining the interest rate applicable to such Loans on the basis provided for
in the definition of Adjusted Eurodollar Rate, Administrative Agent shall on such date give notice
(by telefacsimile or by telephone confirmed in writing) to Company and each Lender of such
determination, whereupon (i) no Loans may be made as, or converted to, Eurodollar Rate Loans until
such time as Administrative Agent notifies Company and Lenders that the circumstances giving rise
to such notice no longer exist and (ii) any Notice of Borrowing or Notice of
Conversion/Continuation given by Company with respect to the Loans in respect of which such
determination was made shall be deemed to be rescinded by Company.

          C. Illegality of Eurodollar Rate Loans. In the event that on any date any Lender shall have
determined (which determination shall be final and conclusive and binding upon all parties hereto
but shall be made only after consultation with Administrative Agent) that the making, maintaining
or continuation of its Eurodollar Rate Loans has become unlawful as a result of compliance by such
Lender in good faith with any law, treaty, governmental rule, regulation, guideline or order which
came into effect after the Closing Date (or would conflict with any such treaty, governmental rule,
regulation, guideline or order not having the force of law even though the failure to comply
therewith would not be unlawful), then, and in any such event, such Lender shall be an “Affected
Lender” and it shall on that day give notice (by telefacsimile or by telephone confirmed in
writing) to Company and Administrative Agent of such determination (which notice Administrative
Agent shall promptly transmit to each other Lender). Thereafter (a) the obligation of the Affected
Lender to make Loans as, or to convert Loans to, Eurodollar Rate Loans shall be suspended until
such notice shall be withdrawn by the Affected Lender, (b) to the extent such determination by the
Affected Lender relates to a Eurodollar Rate Loan then being requested by Company pursuant to a
Notice of Borrowing or a Notice of Conversion/Continuation, the Affected Lender shall make such
Loan as (or convert such Loan to, as the case may be) an Alternate Base Rate Loan, (c) the Affected
Lender’s obligation to maintain its outstanding Eurodollar Rate Loans (the “Affected Loans”) shall
be terminated at the earlier to occur of the expiration of the Interest Period then in effect with

40

 

respect to the Affected Loans or when required by law, and (d) the Affected Loans shall
automatically convert into Alternate Base Rate Loans on the date of such termination.
Notwithstanding the foregoing, to the extent a determination by an Affected Lender as described
above relates to a Eurodollar Rate Loan then being requested by Company pursuant to a Notice of
Borrowing or a Notice of Conversion/Continuation, Company shall have the option, subject to the
provisions of subsection 2.6D, to rescind such Notice of Borrowing or Notice of
Conversion/Continuation as to all Lenders by giving notice (by telefacsimile or by telephone
confirmed in writing) to Administrative Agent of such rescission on the date on which the Affected
Lender gives notice of its determination as described above (which notice of rescission
Administrative Agent shall promptly transmit to each other Lender). Except as provided in the
immediately preceding sentence, nothing in this subsection 2.6C shall affect the obligation of any
Lender other than an Affected Lender to make or maintain Loans as, or to convert Loans to,
Eurodollar Rate Loans in accordance with the terms of this Agreement.

          D. Compensation for Breakage or Non-Commencement of Interest Periods. Company shall
compensate each Lender, upon written request by that Lender (which request shall set forth in
reasonable detail the basis for requesting such amounts), for all reasonable losses, expenses and
liabilities (including any interest paid by that Lender to lenders of funds borrowed by it to make
or carry its Eurodollar Rate Loans and any loss, expense or liability sustained by that Lender in
connection with the liquidation or re-employment of such funds, but excluding loss of profit) which
that Lender may sustain: (i) if for any reason (other than a default by that Lender) a borrowing
of any Eurodollar Rate Loan does not occur on a date specified therefor in a Notice of Borrowing or
a telephonic request for borrowing, or a conversion to or continuation of any Eurodollar Rate Loan
does not occur on a date specified therefor in a Notice of Conversion/Continuation or a telephonic
request for conversion or continuation, (ii) if any prepayment (including any prepayment pursuant
to subsection 2.4A(iii) or 2.4A(vii) or by virtue of the replacement of any Lender pursuant to
subsection 2.8B or 10.6B) or other principal payment or any conversion of any of its Eurodollar
Rate Loans occurs on a date prior to the last day of an Interest Period applicable to that Loan,
(iii) if any prepayment of any of its Eurodollar Rate Loans is not made on any date specified in a
notice of prepayment given by Company, or (iv) as a consequence of any other default by Company in
the repayment of its Eurodollar Rate Loans when required by the terms of this Agreement.

          E. Booking of Eurodollar Rate Loans. Any Lender may make, carry or transfer Eurodollar Rate
Loans at, to, or for the account of any of its branch offices or the office of an Affiliate of that
Lender; provided, that such making, carrying or transferring Eurodollar Rate Loans does not result
in any costs or taxes to Company pursuant to subsection 2.7.

          F. Assumptions Concerning Funding of Eurodollar Rate Loans. Calculation of all amounts
payable to a Lender under this subsection 2.6 and under subsection 2.7A shall be made as though
that Lender had actually funded each of its relevant Eurodollar Rate Loans through the purchase of
a Eurodollar deposit bearing interest at the rate obtained pursuant to the definition of Eurodollar
Rate in an amount equal to the amount of such Eurodollar Rate Loan and having a maturity comparable
to the relevant Interest Period and through the transfer of such

41

 

Eurodollar deposit from an offshore office of that Lender to a domestic office of that Lender
in the United States of America; provided, however, that each Lender may fund each of its
Eurodollar Rate Loans in any manner it sees fit and the foregoing assumptions shall be utilized
only for the purposes of calculating amounts payable under this subsection 2.6 and under subsection
2.7A.

          G. Eurodollar Rate Loans After Default. After the occurrence of and during the continuation
of a Potential Event of Default or an Event of Default if notified by Administrative Agent or the
Requisite Lenders, (i) Company may not elect to have a Loan be made or maintained as, or converted
to, a Eurodollar Rate Loan after the expiration of any Interest Period then in effect for that Loan
and (ii) subject to the provisions of subsection 2.6D, any Notice of Borrowing of Eurodollar Loans
or Notice of Conversion/Continuation which would result in Eurodollar Loans being outstanding given
by Company with respect to a requested borrowing or conversion/continuation that has not yet
occurred shall be deemed to be rescinded by Company.

          2.7 Increased Costs; Taxes; Capital Adequacy

          A. Compensation for Increased Costs and Taxes. Subject to the provisions of subsection 2.7B
(which shall be controlling with respect to the matters covered thereby), in the event that any
Lender shall determine (which determination shall, absent manifest error, be final and conclusive
and binding upon all parties hereto) that any law, treaty or governmental rule, regulation or
order, or any change therein or in the interpretation, administration or application thereof
(including the introduction of any new law, treaty or governmental rule, regulation or order), or
any determination of a Governmental Authority, in each case that becomes effective after the date
hereof (and, for purposes of this Agreement, (x) the Dodd-Frank Wall Street Reform and Consumer
Protection Act and all requests, guidelines or directives in connection therewith and (y) all
requests, rules, guidelines or directives promulgated by the Bank for International Settlements,
the Basel Committee on Banking Supervision (or any successor or similar authority) or the United
States or foreign regulatory authorities, in each case pursuant to Basel III, are deemed to have
gone into effect and adopted after the date hereof), or compliance by such Lender with any
guideline, request or directive issued or made after the date hereof by any Governmental Authority
(whether or not having the force of law):

               (i) subjects such Lender (or its applicable lending office) to any additional Tax
(other than any Tax on the Overall Net Income of such Lender) with respect to this
Agreement or any of its obligations hereunder or any payments to such Lender (or its
applicable lending office) of principal, interest, fees or any other amount payable
hereunder;

               (ii) imposes, modifies or holds applicable any reserve (including any marginal,
emergency, supplemental, special or other reserve), special deposit, compulsory loan, FDIC
insurance or similar requirement against assets held by,

42

 

or deposits or other liabilities in or for the account of, or advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of such Lender
(other than any such reserve or other requirements with respect to Eurodollar Rate Loans
that are reflected in the definition of Adjusted Eurodollar Rate); or

               (iii) imposes any other condition (other than with respect to a Tax matter) on or
affecting such Lender (or its applicable lending office) or its obligations hereunder or
the interbank Eurodollar market; and the result of any of the foregoing is to increase the
cost to such Lender of agreeing to make, making or maintaining Loans hereunder or to reduce
any amount received or receivable by such Lender (or its applicable lending office) with
respect thereto; then, in any such case, Company shall promptly pay to such Lender, upon
receipt of the statement referred to in the next sentence, such additional amount or
amounts (in the form of an increased rate of, or a different method of calculating,
interest or otherwise as such Lender in its sole discretion shall determine) as may be
necessary to compensate such Lender for any such increased cost or reduction in amounts
received or receivable hereunder; provided that Company shall not be required to compensate
a Lender pursuant to this subsection for any increased cost or reduction incurred more than
180 days prior to the date that such Lender notifies Company of such change giving rise to
such increased cost or reduction and of such Lender’s intention to claim compensation
therefor; provided, further, that, if such change giving rise to such increased cost or
reduction is retroactive, then the 180 day period referred to above shall be extended to
include the period of retroactive effect thereof. Such Lender shall deliver to Company
(with a copy to Administrative Agent) a written statement, setting forth in reasonable
detail the basis for calculating the additional amounts owed to such Lender under this
subsection 2.7A, which statement shall be conclusive and binding upon all parties hereto
absent manifest error.

          B. Withholding of Taxes.

               (i) Payments to Be Free and Clear. All sums payable by Company under this Agreement
and the other Loan Documents shall (except to the extent required by law) be paid free and
clear of, and without any deduction or withholding on account of, any Tax (other than a Tax
on the Overall Net Income of any Lender or a Tax measured by or imposed as a result of the
extent and nature of a Lender’s activities, assets, liabilities, leverage, other exposures
to risk or other similar factors) imposed, levied, collected, withheld or assessed by or
within the United States of America or any political subdivision in or of the United States
of America or any other jurisdiction from or to which a payment is made by or on behalf of
Company or by any federation or organization of which the United States of America or any
such jurisdiction is a member at the time of payment.

               (ii) Grossing-Up of Payments. If Company or any other Person is required by law to
make any deduction or withholding on account of any such Tax

43

 

from any sum paid or payable by Company to Administrative Agent or any Lender under
any of the Loan Documents:

               (a) Company shall notify Administrative Agent of any such requirement or any change in
any such requirement as soon as Company becomes aware of it;

               (b) Company shall pay any such Tax before the date on which penalties attach thereto,
such payment to be made (if the liability to pay is imposed on Company) for its own account
or (if that liability is imposed on Administrative Agent or such Lender, as the case may
be) on behalf of and in the name of Administrative Agent or such Lender;

               (c) the sum payable by Company in respect of which the relevant deduction, withholding
or payment is required shall be increased to the extent necessary to ensure that, after the
making of that deduction, withholding or payment, Administrative Agent or such Lender, as
the case may be, receives on the due date a net sum equal to what it would have received
had no such deduction, withholding or payment been required or made; and

               (d) within 30 days after paying any sum from which it is required by law to make any
deduction or withholding, and within 30 days after the due date of payment of any Tax which
it is required by clause (b) above to pay, Company shall deliver to Administrative Agent
evidence satisfactory to the other affected parties of such deduction, withholding or
payment and of the remittance thereof to the relevant taxing or other authority;

provided that no such additional amount shall be required to be paid to any Lender under clause (c)
above except to the extent that any change in any law, treaty or governmental rule, regulation or
order, or any change therein or in the interpretation, administration or application thereof
(including the introduction of any new law, treaty or governmental rule, regulation or order), or
any determination of a Governmental Authority, in each case that becomes effective after the date
hereof (in the case of each Lender listed on the signature pages hereof) or after the date of the
Assignment Agreement pursuant to which such Lender became a Lender (in the case of each other
Lender) affecting any such requirement for a deduction, withholding or payment as is mentioned
therein shall result in an increase in the rate of such deduction, withholding or payment from that
in effect at the date of this Agreement or at the date of such Assignment Agreement, as the case
may be, in respect of payments to such Lender. With respect to FATCA, any regulations or official
interpretations issued after the date hereof (in the case of each Lender listed on the signature
pages hereof) or after the date of the Assignment Agreement pursuant to which such Lender became a
Lender (in the case of each other Lender) shall be considered as law in effect on such date, as the
case may be.

44

 

               (iii) Evidence of Exemption From Withholding Tax.

               (a) Each Lender that is not a United States person as defined in Section 7701(a)(30)
of the Internal Revenue Code (for purposes of this subsection 2.7B(iii), a “Non-US Lender”)
shall deliver to Administrative Agent for transmission to Company, on or prior to the
Closing Date (in the case of each Lender listed on the signature pages hereof) or on or
prior to the date of the Assignment Agreement pursuant to which it becomes a Lender (in the
case of each other Lender), and at such other times as may be necessary in the
determination of Company or Administrative Agent (each in the reasonable exercise of its
discretion), (1) two original copies of Internal Revenue Service Form W-8BEN, Form W-8ECI
or Form W-8IMY, as the case may be (or any successor forms), properly completed and duly
executed by such Lender, together with any other certificate or statement of exemption
required under the Internal Revenue Code or the regulations issued thereunder to establish
that such Lender is not subject to deduction or withholding of United States federal income
tax with respect to any payments to such Lender of principal, interest, fees or other
amounts payable under any of the Loan Documents or (2) if such Lender is not a “bank” or
other Person described in Section 881(c)(3) of the Internal Revenue Code, a Certificate re
Non-Bank Status together with two original copies of Internal Revenue Service Form W-8BEN
or W-8IMY (or any successor form), properly completed and duly executed by such Lender,
together with any other certificates or statements of exemption requested by Company
required under the Internal Revenue Code or the regulations issued thereunder to establish
that such Lender is not subject to deduction or withholding of United States federal income
tax with respect to any payments to such Lender of interest payable under any of the Loan
Documents. Each Lender that is a “United States person” within the meaning of Section
7701(a)(30) of the Internal Revenue Code shall deliver to Administrative Agent for
transmission to Company, on or prior to the Closing Date (in the case of each Lender listed
on the signature pages hereof) or on or prior to the date of the Assignment Agreement
pursuant to which it becomes a Lender (in the case of each other Lender), and at such other
times as it may be necessary in the determination of Company or Administrative Agent (each
in the reasonable exercise of its discretion), two copies of executed originals of Internal
Revenue Service Form W-9 or such other documentation or information prescribed by
applicable laws or reasonably requested by Company or Administrative Agent as will enable
Company or Administrative Agent, as the case may be, to determine whether or not such
Lender is subject to backup withholding or information reporting requirements.

               (b) Each Lender required to deliver any forms, certificates or other evidence with
respect to United States federal income tax withholding matters pursuant to subsection
2.7B(iii)(a) hereby agrees, from time to time after the initial delivery by such Lender of
such forms, certificates or other evidence, whenever a lapse in time or change in
circumstances renders such forms, certificates or other evidence obsolete or inaccurate in
any material respect, that such Lender shall promptly (1) deliver to Administrative Agent
for transmission to Company two new original copies of Internal Revenue Service Form
W-8BEN, W-8ECI or W-8IMY, as the case may be, or a

45

 

Certificate re Non-Bank Status and two original copies of Internal Revenue Service
Form W-8BEN or W-8IMY, as the case may be, properly completed and duly executed by such
Lender, together with any other certificates or statements of exemption requested by
Company required in order to confirm or establish that such Lender is not subject to
deduction or withholding of United States federal income tax with respect to payments to
such Lender under the Loan Documents or (2) notify Administrative Agent and Company of its
inability to deliver any such forms, certificates or other evidence.

               (c) Company shall not be required to pay any additional amount to any Lender under
clause (c) of subsection 2.7B(ii) if such Lender shall have failed to satisfy the
requirements of clause (a), (b)(1) or (d) of this subsection 2.7B(iii); provided that if
such Lender shall have satisfied the requirements of subsection 2.7B(iii)(a) on the Closing
Date (in the case of each Lender listed on the signature pages hereof) or on the date of
the Assignment Agreement pursuant to which it became a Lender (in the case of each other
Lender), nothing in this subsection 2.7B(iii)(c) shall relieve Company of its obligation to
pay any additional amounts pursuant to clause (c) of subsection 2.7B(ii) in the event that,
as a result of any change in any applicable law, treaty or governmental rule, regulation or
order, or any change in the interpretation, administration or application thereof, such
Lender is no longer properly entitled to deliver forms, certificates or other evidence at a
subsequent date establishing the fact that such Lender is not subject to withholding as
described in subsection 2.7B(iii)(a).

               (d) If a payment made to a Lender under this Agreement would be subject to U.S.
Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the
applicable reporting requirements of FATCA (including those contained in Section 1471(b) or
1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the
Withholding Agent, at the time or times prescribed by law and at such time or times
reasonably requested by the Withholding Agent, such documentation prescribed by applicable
law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and
such additional documentation reasonably requested by the Withholding Agent as may be
necessary for the Withholding Agent to comply with its obligations under FATCA, to
determine that such Lender has complied with such Lender’s obligations under FATCA or to
determine the amount to deduct and withhold from such payment. For purposes of this
subsection 2.7B(iii)(d), FATCA shall include any regulations or official interpretations
thereof.

          C. Capital Adequacy Adjustment. If any Lender shall have determined that the adoption,
effectiveness, phase-in or applicability after the date hereof of any law, rule or regulation (or
any provision thereof) regarding capital adequacy, or any change therein or in the interpretation
or administration thereof by any Governmental Authority charged with the interpretation or
administration thereof, or compliance by any Lender (or its applicable lending office) with any
guideline, request or directive regarding capital adequacy (whether or not having the force of law)
of any such Governmental Authority has or would have the effect of reducing the rate of return on
the capital of such Lender or any corporation controlling such Lender as a

46

 

consequence of, or with reference to, such Lender’s Loans or Commitments or other obligations
hereunder with respect to the Loans to a level below that which such Lender or such controlling
corporation could have achieved but for such adoption, effectiveness, phase-in, applicability,
change or compliance (taking into consideration the policies of such Lender or such controlling
corporation with regard to capital adequacy), then from time to time, within five Business Days
after receipt by Company from such Lender of the statement referred to in the next sentence,
Company shall pay to such Lender such additional amount or amounts as will compensate such Lender
or such controlling corporation on an after-tax basis for such reduction; provided that Company
shall not be required to compensate a Lender pursuant to this subsection for any reduction incurred
more than 180 days prior to the date that such Lender notifies Company of such change giving rise
to such reduction and of such Lender’s intention to claim compensation therefor; provided, further,
that, if such change giving rise to such reduction is retroactive, then the 180 day period referred
to above shall be extended to include the period of retroactive effect thereof. Such Lender shall
deliver to Company (with a copy to Administrative Agent) a written statement, setting forth in
reasonable detail the basis of the calculation of such additional amounts, which statement shall be
conclusive and binding upon all parties hereto absent manifest error.

          D. Refund and Contest. If Administrative Agent or any Lender receives a refund with respect
to Tax deducted, withheld or paid by Company and with respect to which Company has been required to
and has paid an additional amount under this subsection 2.7, which in the good faith judgment of
such Lender is allocable to such deduction, withholding or payment, it shall promptly pay such
refund, together with any other amount paid by Company in connection with such refunded Tax and any
interest paid by the relevant Governmental Authority with respect to such refund, to Company, net
of all unreimbursed out-of-pocket expenses of such Lender incurred in obtaining such refund,
provided, however, that Company agrees to promptly return such refund to Administrative Agent or
the applicable Lender, as the case may be, if it receives notice from Administrative Agent or
applicable Lender that such Administrative Agent or Lender is required to repay such refund. Each
of Administrative Agent and such Lender agrees that it will contest such Tax or liabilities paid by
Company if Administrative Agent or such Lender determines, in its sole discretion, that it would
not be materially disadvantaged or prejudiced as a result of such contest.

          2.8 Obligation of Lenders to Mitigate; Replacement

          A. Mitigation. Each Lender agrees that, as promptly as practicable after the officer of such
Lender responsible for administering the Loans of such Lender becomes aware of the occurrence of an
event or the existence of a condition that would cause such Lender to become an Affected Lender or
that would entitle such Lender to receive payments under subsection 2.7, it will, to the extent not
inconsistent with the internal policies of such Lender and any applicable legal or regulatory
restrictions, use reasonable efforts (i) to make, issue, fund or maintain the Commitments of such
Lender or the affected Loans of such Lender through another lending office of such Lender, or (ii)
take such other measures as such Lender may deem reasonable, which may include assignment of its
rights and obligations hereunder to another of

47

 

its offices, branches or affiliates, if as a result thereof the circumstances which would
cause such Lender to be an Affected Lender would cease to exist or the additional amounts which
would otherwise be required to be paid to such Lender pursuant to subsection 2.7 would be
materially reduced and if, as determined by such Lender in its sole discretion, the making,
issuing, funding or maintaining of such Commitments or Loans through such other lending office or
in accordance with such other measures, including assignment, as the case may be, would not
otherwise materially adversely affect such Commitments or Loans or the interests of such Lender;
provided that such Lender will not be obligated to utilize such other lending office pursuant to
this subsection 2.8 unless Company agrees to pay all reasonable incremental expenses incurred by
such Lender as a result of utilizing such other lending office as described in clause (i) above. A
certificate as to the amount of any such expenses payable by Company pursuant to this subsection
2.8 (setting forth in reasonable detail the basis for requesting such amount) submitted by such
Lender to Company (with a copy to Administrative Agent) shall be conclusive absent manifest error.

          B. Replacement. In the event of (a) a refusal by a Lender to consent to a proposed change,
waiver, discharge or termination with respect to this Agreement which has been approved by
Requisite Lenders (but requires consent of all Lenders) as provided in subsection 10.6, (b) any
Lender becomes an Affected Lender or requests compensation under subsection 2.7A or 2.7C, (c)
Company is required to pay any additional amount to any Lender or any Governmental Authority for
the account of any Lender pursuant to subsection 2.7B, or (d) any Lender becomes a Defaulting
Lender, then Company may, at its sole expense and effort, replace such Lender (a “Replaced Lender”)
with one or more Eligible Assignees (collectively, the “Replacement Lender”) reasonably acceptable
to Administrative Agent, provided that (i) at the time of any replacement pursuant to this
subsection 2.8 the Replacement Lender shall enter into one or more Assignment Agreements pursuant
to subsection 10.1B (and with all fees payable pursuant to such subsection 10.1B to be paid by the
Replacement Lender) pursuant to which the Replacement Lender shall acquire all of the outstanding
Loans and Commitments of the Replaced Lender and, in connection therewith, shall pay to the
Replaced Lender in respect thereof an amount equal to the sum of (A) an amount equal to the
principal of, and all accrued interest on, all outstanding Loans of the Replaced Lender and (B) an
amount equal to all accrued, but theretofore unpaid, fees owing to the Replaced Lender with respect
thereto and (ii) all obligations (including without limitation all such amounts, if any, owing
under subsection 2.6D) of Company owing to the Replaced Lender (other than those specifically
described in clause (i) above in respect of which the assignment purchase price has been, or is
concurrently being, paid), shall be paid in full to such Replaced Lender concurrently with such
replacement. Upon the execution of the respective Assignment Agreements and the acceptance thereof
by Administrative Agent pursuant to subsection 10.1B, the payment of amounts referred to in clauses
(i) and (ii) above and, if so requested by the Replacement Lender, delivery to the Replacement
Lender of the appropriate Note or Notes executed by Company, the Replacement Lender shall become a
Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder except with
respect to indemnification provisions under this Agreement which by the terms of this Agreement
survive the termination of this Agreement, which indemnification provisions shall survive as to
such Replaced Lender. A Lender shall not be required to make any such assignment and delegation
if, prior thereto, as a result of a waiver by such Lender or

48

 

otherwise, the circumstances entitling Company to require such assignment and delegation cease
to apply.

the following statements are true, correct and complete:

          5.1 Organization, Powers, Qualification, Good Standing, Business and Subsidiaries

          A. Organization and Powers. Each Loan Party is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization as specified in Schedule 5.1 annexed

contemplated thereby.

          B. Qualification and Good Standing. Each Loan Party is qualified to do business and in good
standing in every jurisdiction where its assets are located and wherever necessary to carry out its
business and operations, except in jurisdictions where the failure to be so qualified or in good
standing has not had and could not reasonably be expected to have a Material Adverse Effect.

          C. Conduct of Business. Company and its Subsidiaries are engaged only in the businesses
permitted to be engaged in pursuant to subsection 7.10.

          D. Subsidiaries. All of the Subsidiaries of Company are identified in Schedule 5.1 annexed

identified in Schedule 5.1 annexed hereto (as so supplemented) are duly authorized, validly issued,
fully paid and nonassessable and free and clear of all liens except liens created by the Loan
Documents and liens permitted thereunder and none of such capital stock constitutes Margin Stock.
Each of the Subsidiaries of Company identified in Schedule 5.1 annexed hereto (as so supplemented)
is duly organized, validly existing and in good standing under the laws of its respective
jurisdiction of organization set forth therein, has all requisite corporate or other power and
authority to own and operate its properties and to carry on its business as now conducted and as
proposed to be conducted and is qualified to do business and in good standing in every jurisdiction
where its assets are located and wherever necessary to carry out its business and operations, in
each case except where failure to be so qualified or in good standing or a lack of such corporate
or other power and authority has not had and is not reasonably expected to have a Material Adverse
Effect. Schedule 5.1 annexed hereto (as so supplemented) correctly sets forth the ownership
interest of Company and each of its Subsidiaries in each of the Subsidiaries of Company identified
therein.

and the consummation of the transactions contemplated by the Loan Documents do not and will not (i)
violate the Certificate or Articles of Incorporation or Bylaws (or other organizational documents)
of Company or any of its Subsidiaries, (ii) violate any provision of any law or any governmental

any Person under any Contractual Obligation of Company or any of its Subsidiaries, except for such
approvals or consents which will be obtained on or before the Funding Date and disclosed in writing
to Lenders, which in the case of clauses (ii), (iii) and (v), individually or in the aggregate,
would not reasonably be expected to have a Material Adverse Effect.

          C. Governmental Consents. The execution, delivery and performance by Loan Parties of the Loan
Documents and the consummation of the transactions contemplated by the Loan Documents do not and
will not require any registration with, consent or approval of, or notice to, or other action to,
with or by, any Governmental Authority, except such as have been obtained or made and are in full
force and effect and except as have not resulted, and would not reasonably be expected to result,
in a Material Adverse Effect.

          D. Binding Obligation. This Agreement has been duly executed and delivered by each of ESRX
and Aristotle, and each other Loan Document has been or will be duly executed and delivered by each
Loan Party that is to be a party thereto and is or, when executed, will be the legally valid and

respective terms, subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting creditors’ rights

law) and (iii) an implied covenant of good faith and fair dealing.

of the entities described in such financial statements as at the date thereof and the results of
operations and cash flows (on a consolidated basis) of the entities described therein for the
period then ended. Company does not (and will not immediately following the Closing Date) have any
Contingent Obligation, contingent liability or liability for taxes, long-term lease or unusual
forward or long-term commitment that is not reflected in the foregoing financial statements or the
notes thereto other than those incurred in the ordinary course of business or otherwise that

Material Adverse Effect.

          5.4 No Material Adverse Change

their respective properties and assets necessary or useful for the conduct of their business, in
each case except for assets disposed of since the date of the most recent financial statements
received by Administrative Agent in the ordinary course of business or as otherwise permitted under
subsection 7.5 and except where failure to have such title would not, individually or in the
aggregate, have a Material Adverse Effect. Except as permitted by this Agreement, all such
properties and assets are free and clear of Liens.

          5.6 Litigation; Adverse Facts

          Except as set forth on Schedule 5.6, there are no actions, suits, proceedings, arbitrations or
governmental investigations (whether or not purportedly on behalf of Company or any of its
Subsidiaries) at law or in equity, or before or by any Governmental Authority (including any
Environmental Claims) that are pending or, to the knowledge of Company, threatened against or
affecting Company or any of its Subsidiaries or any property, license or registration of Company or
any of its Subsidiaries and that, individually or in the aggregate, could reasonably be expected to
result in a Material Adverse Effect. Neither Company nor any of its Subsidiaries (i) is in
violation of any applicable laws (including those involving the

55

 

licensing or registration relating to the pharmaceutical and healthcare services provided by
Company and its Subsidiaries and Environmental Laws) that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect, or (ii) is subject to or in default

charges upon Company and its Subsidiaries and upon their respective properties, assets, income,
businesses and franchises which are due and payable have been paid when due and payable, except for
Taxes that are being contested in good faith by appropriate proceedings for which Company or
relevant Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with
GAAP, and in either case, to the extent that the failure to do so would not reasonably be expected
to result in a Material Adverse Effect. Company knows of no proposed material Tax assessment
against Company or any of its Subsidiaries which is not being actively contested by Company or such
Subsidiary in good faith and by appropriate proceedings; provided that reserves or other
appropriate provisions, if any, as shall be required in conformity with GAAP shall have been made
or provided therefor.

          5.8 Performance of Agreements

          Neither Company nor any of its Subsidiaries is in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in any of its Contractual
Obligations, and no condition exists that, with the giving of notice or the lapse of time or both,
would constitute such a default, except where the consequences, direct or indirect, of such default
or defaults, if any, could not reasonably be expected to have a Material Adverse Effect.

          C. As of the most recent valuation date for any Pension Plan, the amount of unfunded benefit
liabilities (as defined in Section 4001(a)(18) of ERISA), individually or in the aggregate for all
Pension Plans (excluding for purposes of such computation any Pension Plans with respect to which
assets exceed benefit liabilities), which if amortized over ten years, would not reasonably be
expected, after considering the financial condition of all relevant ERISA Affiliates who could have
liability in respect of such liabilities, to result in a Material Adverse Effect.

          D. For each Multiemployer Plan as of the most recent valuation date for which an actuarial
report has been received, the potential liability of Company, its Subsidiaries and their respective
ERISA Affiliates for a complete withdrawal from such Multiemployer Plan (within the meaning of
Section 4203 of ERISA), when aggregated with such potential liability for a complete withdrawal
from all Multiemployer Plans, based on information available pursuant to Section 4221(e) of ERISA,
would not reasonably be expected to result in a Material Adverse Effect.

Document or in any other document, certificate or written statement furnished to Lenders by or on
behalf of Company or any of its Subsidiaries for use in connection with the transactions
contemplated by this Agreement, taken as a whole, contains any untrue statement of a material fact
or omits to state a material fact (known to Company in the case of any document not furnished by
it) necessary in order to make the statements contained herein or therein not misleading in light
of the circumstances in which the same were made; provided, that no representation is made as to
projections or pro forma financial information except as set forth in the next sentence. Any
projections and pro forma financial information contained in such materials are based upon good
faith estimates and assumptions believed by Company to be reasonable at the time made, it being
recognized by Lenders that such projections as to future events are not to be viewed as facts and

any individual in the ordinary course and not for reasons related to an actual or proposed
change of control of Company) to constitute a majority of the board of directors of
Company; or

          8.12 Invalidity of Subsidiary Guaranty; Repudiation of Obligations

          At any time after the execution and delivery thereof, (i) the Subsidiary Guaranty for any
reason, other than the satisfaction in full of all Obligations, shall cease to be in full force and
effect (other than in accordance with its terms) or shall be declared to be null and void or (ii)
any Loan Party shall contest the validity or enforceability of any Loan Document in writing or deny

obligation of each Lender to make any Loan shall thereupon terminate, and (ii) upon the occurrence
and during the continuation of any other Event of Default, Administrative Agent shall, upon the
written request or with the written consent of Requisite Lenders, by written notice to

74

 

Company, declare all or any portion of the amounts described in clauses (a) and (b) above to be,

          Notwithstanding anything contained in the preceding paragraph, if at any time within 60 days
after an acceleration of the Loans pursuant to clause (ii) of such paragraph Company shall pay all
arrears of interest and all payments on account of principal which shall have become due otherwise
than as a result of such acceleration (with interest on principal and, to the extent permitted by
law, on overdue interest, at the rates specified in this Agreement) and all Events of Default and
Potential Events of Default (other than non-payment of the principal of and accrued interest on the
Loans, in each case which is due and payable solely by virtue of acceleration) shall be remedied or
waived pursuant to subsection 10.6, then Requisite Lenders, by written notice to Company, may at
their option rescind and annul such acceleration and its consequences; but such action shall not
affect any subsequent Event of Default or Potential Event of Default or impair any right consequent
thereon. The provisions of this paragraph are intended merely to bind Lenders to a decision which
may be made at the election of Requisite Lenders and are not intended, directly or indirectly, to
benefit Company, and such provisions shall not at any time be construed so as to grant Company the
right to require Lenders to rescind or annul any acceleration hereunder or to preclude Agents or
Lenders from exercising any of the rights or remedies available to them under any of the Loan
Documents, even if the conditions set forth in this paragraph are met.

     Section 9. AGENTS

          9.1 Appointment

          Credit Suisse is hereby appointed as Administrative Agent hereunder and under the other Loan
Documents, and each Lender hereby authorizes Administrative Agent to act as its agent in accordance
with the terms of this Agreement and the other Loan Documents. Administrative Agent agrees to act
upon the express conditions contained in this Agreement and the other Loan Documents, as
applicable. The provisions of this Section 9 are solely for the benefit of Administrative Agent
and Lenders and Company shall have no rights as a third party beneficiary of any of the provisions
thereof. In performing its functions and duties under this Agreement, Administrative Agent shall
act solely as an agent of Lenders and does not assume and shall not be deemed to have assumed any
obligation towards or relationship of agency or trust with or for Company or any of its
Subsidiaries. Anything herein to the contrary notwithstanding, none of the financial institutions
listed on the cover page hereof shall have any powers, duties or responsibilities under this
Agreement or any of the other Loan Documents, except in its capacity, as applicable, as
Administrative Agent or a Lender hereunder.

          9.2 Powers and Duties; General Immunity

75

 

          A. Powers; Duties Specified. Each Lender irrevocably authorizes Administrative Agent to take
such action on such Lender’s behalf and to exercise such powers, rights and remedies hereunder and
under the other Loan Documents as are specifically delegated or granted to Administrative Agent by
the terms hereof and thereof, together with such powers, rights and remedies as are reasonably
incidental thereto. Administrative Agent shall have only those duties and responsibilities that
are expressly specified in this Agreement and the other Loan Documents. Administrative Agent may
exercise such powers, rights and remedies and perform such duties by or through its agents or
employees. Administrative Agent shall not have, by reason of this Agreement or any of the other
Loan Documents, a fiduciary relationship in respect of any Lender; and nothing in this Agreement or
any of the other Loan Documents, expressed or implied, is intended to or shall be so construed as
to impose upon Administrative Agent any obligations in respect of this Agreement or any of the
other Loan Documents except as expressly set forth herein or therein.

          B. No Responsibility for Certain Matters. Administrative Agent shall not be responsible to
any Lender for the execution, effectiveness, genuineness, validity, enforceability, collectibility
or sufficiency of this Agreement or any other Loan Document or for any representations, warranties,
recitals or statements made herein or therein or made in any written or oral statements or in any
financial or other statements, instruments, reports or certificates or any other documents
furnished or made by Administrative Agent to Lenders or by or on behalf of Company to
Administrative Agent or any Lender in connection with the Loan Documents and the transactions
contemplated thereby or for the financial condition or business affairs of Company or any other
Person liable for the payment of any Obligations, nor shall Administrative Agent be required to
ascertain or inquire as to the performance or observance of any of the terms, conditions,
provisions, covenants or agreements contained in any of the Loan Documents or as to the use of the
proceeds of the Loans or as to the existence or possible existence of any Event of Default or
Potential Event of Default. Anything contained in this Agreement to the contrary notwithstanding,
Administrative Agent shall not have any liability arising from confirmations of the amount of
outstanding Loans or the component amounts thereof.

          C. Exculpatory Provisions. Neither Administrative Agent nor any of its officers, directors,
employees or agents shall be liable to Lenders for any action taken or omitted by it under or in
connection with any of the Loan Documents except to the extent caused by Administrative Agent’s
gross negligence or willful misconduct. Administrative Agent shall be entitled to refrain from any
act or the taking of any action (including the failure to take an action) in connection with this
Agreement or any of the other Loan Documents or from the exercise of any power, discretion or
authority vested in it hereunder or thereunder unless and until Administrative Agent shall have
received instructions in respect thereof from Requisite Lenders (or such other Lenders as may be
required to give such instructions under subsection 10.6) and, upon receipt of such instructions
from Requisite Lenders (or such other Lenders, as the case may be), Administrative Agent shall be
entitled to act or (where so instructed) refrain from acting, or to exercise such power, discretion
or authority, in accordance with such instructions. Administrative Agent shall be deemed to have
no knowledge of any Potential Event of Default unless and until written notice thereof is given to
Administrative Agent by Company or any Lender. Without prejudice to the generality of the
foregoing, (i) Administrative Agent shall be

76

 

entitled to rely, and shall be fully protected in relying, upon any communication, instrument
or document believed by it to be genuine and correct and to have been signed or sent by the proper
person or persons, and shall be entitled to rely and shall be protected in relying on opinions and
judgments of attorneys (who may be attorneys for Company and its Subsidiaries), accountants,
experts and other professional advisors selected by it; and (ii) no Lender shall have any right of
action whatsoever against Administrative Agent as a result of Administrative Agent acting or (where
so instructed) refraining from acting under this Agreement or any of the other Loan Documents in
accordance with the instructions of Requisite Lenders (or such other Lenders as may be required to
give such instructions under subsection 10.6).

          D. Administrative Agent Entitled to Act as Lender. The agency hereby created shall in no way
impair or affect any of the rights and powers of, or impose any duties or obligations upon,
Administrative Agent in its individual capacity as a Lender hereunder. With respect to its Loans,
Administrative Agent shall have the same rights and powers hereunder as any other Lender and may
exercise the same as though it were not performing the duties and functions delegated to it
hereunder, and the term “Lender” or “Lenders” or any similar term shall, unless the context clearly
otherwise indicates, include Administrative Agent in its individual capacity. Administrative Agent
and its Affiliates may accept deposits from, lend money to and generally engage in any kind of
banking, trust, financial advisory or other business with Company or any of its Affiliates as if it
were not performing the duties specified herein, and may accept fees and other consideration from
Company for services in connection with this Agreement and otherwise without having to account for
the same to Lenders.

          9.3 Representations and Warranties; No Responsibility for Appraisal of Creditworthiness

          Each Lender represents and warrants that it has made its own independent investigation of the
financial condition and affairs of Company and its Subsidiaries in connection with the making of
the Loans hereunder and that it has made and shall continue to make its own appraisal of the
creditworthiness of Company and its Subsidiaries. Administrative Agent shall not have any duty or
responsibility, either initially or on a continuing basis, to make any such investigation or any
such appraisal on behalf of Lenders or to provide any Lender with any credit or other information
with respect thereto, whether coming into its possession before the making of the Loans or at any
time or times thereafter, and Administrative Agent shall not have any responsibility with respect
to the accuracy of or the completeness of any information provided to Lenders.

          9.4 Right to Indemnity

          Each Lender, in proportion to its Pro Rata Share, severally agrees to indemnify Administrative
Agent, to the extent that Administrative Agent shall not have been reimbursed by Company, for and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses (including counsel fees and disbursements) or disbursements of

77

 

any kind or nature whatsoever which may be imposed on, incurred by or asserted against
Administrative Agent in exercising its powers, rights and remedies or performing its duties
hereunder or under the other Loan Documents or otherwise in its capacity as Administrative Agent,
in any way relating to or arising out of this Agreement or the other Loan Documents; provided that
no Lender shall be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such
Administrative Agent’s gross negligence or willful misconduct. If any indemnity furnished to an
Administrative Agent for any purpose shall, in the opinion of such Administrative Agent, be
insufficient or become impaired, such Administrative Agent may call for additional indemnity and
cease, or not commence, to do the acts indemnified against until such additional indemnity is
furnished.

          9.5 Successor Agent

          Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof to
Lenders and Company. Upon any such notice of resignation, Requisite Lenders shall have the right,
with, so long as no Potential Event of Default or Event of Default shall have occurred and be
continuing, the consent of Company (not to be unreasonably withheld or delayed), to appoint a
successor. If no successor shall have been so appointed by the Requisite Lenders and shall have
accepted such appointment within 30 days after the resigning Administrative Agent gives notice of
its resignation, then the resigning Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent which shall be a bank with an office in New York, New York, or an
Affiliate of any such bank. If no successor Administrative Agent has been appointed pursuant to
the immediately preceding sentence by the 30th day after the date such notice of resignation was
given by such Administrative Agent, such Administrative Agent’s resignation shall become effective
and the Requisite Lenders shall thereafter perform all the duties of such Administrative Agent
hereunder and/or under any other Loan Document until such time, if any, as the Requisite Lenders
appoint a successor Administrative Agent. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, that successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, as the case may be, and the retiring Administrative Agent shall be
discharged from its duties and obligations under this Agreement. After any retiring Administrative
Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 9 shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was Administrative
Agent under this Agreement.

          9.6 Guarantees

          Each Lender hereby further authorizes Administrative Agent, on behalf of and for the benefit
of Lenders, to be the agent for and representative of Lenders under the Subsidiary Guaranty, and
each Lender agrees to be bound by the terms of the Subsidiary Guaranty; provided that
Administrative Agent shall not enter into or consent to any amendment, modification, termination or
waiver of any provision contained in the Subsidiary Guaranty; provided further,

78

 

however, that, without further written consent or authorization from Lenders, Administrative
Agent may execute any documents or instruments necessary to release any Subsidiary Guarantor from
the Subsidiary Guaranty if all of the capital stock of such Subsidiary Guarantor is sold to any
Person pursuant to a sale or other disposition permitted hereunder or to which Requisite Lenders
have otherwise consented. Anything contained in any of the Loan Documents to the contrary
notwithstanding, Company, Administrative Agent and each Lender hereby agree that no Lender shall
have any right individually to enforce the Subsidiary Guaranty, it being understood and agreed that
all rights and remedies under the Subsidiary Guaranty may be exercised solely by Administrative
Agent for the benefit of Lenders in accordance with the terms thereof.

     Section 10. MISCELLANEOUS

          10.1 Assignments and Participations in Loans

          A. General. Subject to subsection 10.1B, each Lender shall have the right at any time to (i)
sell, assign or transfer to any Eligible Assignee, or (ii) sell participations to any Person (a
“Participant”) in, all or any part of its Commitments or any Loan or Loans made by it or in any
case its rights or obligations with respect thereto or participations therein or any other interest
herein or in any other obligations owed to it; provided, further, that no such sale, assignment or
transfer described in clause (i) above shall be effective unless and until an Assignment Agreement
effecting such sale, assignment or transfer shall have been accepted by Administrative Agent and
recorded in the Register as provided in subsection 10.1B(ii). Except as otherwise provided in this
subsection 10.1, no Lender shall, as between Company and such Lender, be relieved of any of its
obligations hereunder as a result of any sale, assignment or transfer of, or any granting of
participations in, all or any part of its Commitments or the Loans or the other Obligations owed to
such Lender. Each Lender that sells a participation to any Participant shall, acting solely for
this purpose as a non-fiduciary agent of Company, maintain a register on which it enters the name
and address of each Participant and the principal and interest amounts of each Participant’s
interest in the Loans or other obligations under this Agreement (a “Participant Register”). The
entries in the Participant Register shall be conclusive absent manifest error, and such Lender
shall treat each Participant whose name is recorded in the Participant Register as the owner of
such participation for all purposes of this Agreement notwithstanding any notice to the contrary;
provided that no Lender shall have any obligation to disclose all or any portion of the Participant
Register to Company or any other Person (including the identity of any Participant or any
information relating to a Participant’s interest under the Loan Documents) except to the extent
that such disclosure is necessary to establish that the Loans or other obligations under the Loan
Documents are in registered form under Section 5f.103-1(c) of the United States Treasury
Regulations.

          B. Assignments.

               (i) Amounts and Terms of Assignments. Each Commitment, Loan or other Obligation may
be assigned in an aggregate amount of not less than

79

 

$1,000,000 in the case of Loans and Commitments (or (x) in each case, such lesser
amount as shall constitute the aggregate amount of the Commitments, Loans and other
Obligations of the assigning Lender or (y) in the event of simultaneous assignments by or
to two or more Approved Funds such assignments shall be combined for purposes of
determining whether the minimum assignment requirement as set forth above is met) to any
other Eligible Assignee without the consent of (but with notice to) Company and with the
consent of Administrative Agent (which consent shall not be unreasonably withheld or
delayed); provided that any assignment prior to the Funding Date other than to a Permitted
Lender shall also require the consent of Company (which consent shall not be unreasonably
withheld or delayed). If Company has not responded within ten Business Days to any request
for an assignment, Company shall be deemed to have consented to such assignment. To the
extent of any such assignment in accordance with the above, the assigning Lender shall be
relieved of its obligations with respect to its Commitments, Loans or other obligations or
the portion thereof so assigned. The parties to each such assignment shall (i)
electronically execute and deliver to Administrative Agent an Assignment Agreement via an
electronic settlement system acceptable to Administrative Agent (which initially shall be
ClearPar, LLC) or (ii) manually execute and deliver to Administrative Agent an Assignment
Agreement, in each case, together with a (x) processing and recordation fee of US$3,500
(which may be reduced or waived in the sole discretion of Administrative Agent), (y) an
Administrative Questionnaire, substantially in the form of Exhibit VIII annexed hereto, if
the Eligible Assignee shall not already be a Lender hereunder and (z) such forms,
certificates or other evidence, if any, with respect to United States federal income tax
withholding matters as the assignee under such Assignment Agreement may be required to
deliver to Administrative Agent pursuant to subsection 2.7B(iii)(a). Upon such execution,
delivery, acceptance and recordation, from and after the effective date specified in such
Assignment Agreement, (y) 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 Agreement, shall have the rights and obligations of a Lender hereunder and (z)
the assigning Lender thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment Agreement, relinquish its rights
(other than any rights which survive the termination of this Agreement under subsection
10.9B) and be released from its obligations under this Agreement (and, in the case of an
Assignment Agreement 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. The
Commitments hereunder shall be modified to reflect the Commitment of such assignee and any
remaining Commitment of such assigning Lender and, if any such assignment occurs after the
issuance of the Notes hereunder, the assigning Lender shall, upon the effectiveness of such
assignment or as promptly thereafter as practicable, surrender its Note to Administrative
Agent for cancellation, and thereupon a new Note shall be issued to the assignee and/or to
the assigning Lender, substantially in the form of Exhibit IV annexed hereto, as the case
may be, with appropriate insertions, to reflect the new Commitments and/or outstanding
Loans, as the case may be, of the assignee and/or the assigning Lender.

80

 

               (ii) Acceptance by Administrative Agent; Recordation in Register. Upon its receipt of
an Assignment Agreement executed by an assigning Lender and an assignee representing that
it is an Eligible Assignee, together with (x) the processing and recordation fee referred
to in subsection 10.1B(i), (y) an Administrative Questionnaire, substantially in the form
of Exhibit VIII annexed hereto, completed in respect of the Eligible Assignee (unless the
Eligible Assignee shall already be a Lender hereunder) and (z) any forms, certificates or
other evidence with respect to United States federal income tax withholding matters that
such assignee may be required to deliver to Administrative Agent pursuant to subsection
2.7B(iii)(a), Administrative Agent shall, if Administrative Agent and Company have
consented to the assignment evidenced thereby (in each case to the extent such consent is
required pursuant to subsection 10.1B(i)), (a) accept such Assignment Agreement by
executing a counterpart thereof as provided therein (which acceptance shall evidence any
required consent of Administrative Agent to such assignment) and (b) promptly record the
information contained therein in the Register. The Register shall be available for
inspection by Company and any Lender at any reasonable time and from time to time upon
reasonable prior notice. Administrative Agent shall maintain a copy of each Assignment
Agreement delivered to and accepted by it as provided in this subsection 10.1B(ii).

          C. Participations. Each Participant, other than any Participant that is an Affiliate of the
Lender granting such participation, shall not be entitled to require such Lender to take or omit to
take any action hereunder except action directly affecting (i) the extension of the scheduled final
maturity date of any Loan or Commitment allocated to such participation, (ii) a reduction of the
principal amount of, the rate of interest payable or the fees payable on any Loan or Commitment
allocated to such participation or (iii) a release of all or substantially all the value of the
Subsidiary Guaranty, in each case other than in accordance with the terms of the Loan Documents,
and all amounts payable by Company hereunder (including amounts payable to such Lender pursuant to
subsections 2.6D and 2.7) shall be determined as if such Lender had not sold such participation.
Company and each Lender hereby acknowledge and agree that, solely for purposes of subsections 10.4
and 10.5, (a) any participation will give rise to a direct obligation of Company to the Participant
and (b) the Participant shall be considered to be a “Lender”.

          D. Pledges of Obligations. In addition to the assignments and participations permitted under
the foregoing provisions of this subsection 10.1, any Lender may assign and pledge all or any
portion of its Loans, the other Obligations owed to such Lender, and its Notes to secure
obligations of such Lender including without limitation any assignment or pledge to a Federal
Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any operating circular issued by such Federal Reserve Bank; provided
that (i) no Lender shall, as between Company and such Lender, be relieved of any of its obligations
hereunder as a result of any such assignment and pledge and (ii) in no event shall such Federal
Reserve Bank be considered to be a “Lender” or be entitled to require the assigning Lender to take
or omit to take any action hereunder.

81

 

          E. Assignments to Special Purpose Funding Vehicles. In addition to the assignments and
participations permitted under the foregoing provisions of this subsection 10.1, any Lender (a
“Granting Lender”) may grant to special purpose funding vehicle (an “SPV”), identified as such in
writing from time to time by the Granting Lender to Administrative Agent and Company, the option to
provide to Company all or any part of any Loan that such Granting Lender would otherwise be
obligated to make Company pursuant to this Agreement; provided, (i) nothing herein shall constitute
a commitment by any SPV to make any Loan and (ii) if an SPV elects not to exercise such option or
otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to
make such Loan pursuant to the terms hereof. The making of a Loan by an SPV hereunder shall
utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by
such Granting Lender. Each party hereto hereby agrees that no SPV shall be liable for any
indemnity or similar payment obligation under this Agreement (all liability for which shall remain
with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which
agreement shall survive the termination of this Agreement) that, prior to the date that is one year
and one day after the payment in full of all outstanding commercial paper or other senior
indebtedness of any SPV, it will not institute against, or join any other person in instituting
against, such SPV, any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State thereof. In addition, notwithstanding
anything to the contrary contained in this subsection 10.1E(i), any SPV may (i) with notice to, but
without the prior written consent of, Company and Administrative Agent and without paying any
processing fee therefor, assign all or a portion of its interests in any Loan to the Granting
Lender or to any financial institutions (consented to by Administrative Agent) providing liquidity
and/or credit support to or for the account of such SPV to support the funding or maintenance of
Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to
any rating agency, commercial paper dealer or provider of any surety, guarantee or credit liquidity
enhancement to such SPV. After the date of a grant to any SPV, this section may not be amended
without the written consent of such SPV.

          F. Information. Each Lender may furnish any information concerning Company and its
Subsidiaries in the possession of that Lender from time to time to assignees and participants
(including prospective assignee and participants), subject to subsection 10.19.

          G. Representations of Lenders. Each Lender listed on the signature pages hereof hereby
represents and warrants (i) that it is an Eligible Assignee described in clause (A) of the
definition thereof; (ii) that it has experience and expertise in the making of or investing in
loans such as the Loans; and (iii) that it will make or invest in its Loans for its own account in
the ordinary course of its business and without a view to distribution of such Loans within the
meaning of the Securities Act or the Exchange Act or other federal securities laws (it being
understood that, subject to the provisions of this subsection 10.1, the disposition of such Loans
or any interests therein shall at all times remain within its exclusive control). Each Lender that
becomes a party hereto pursuant to an Assignment Agreement shall be deemed to agree that the
representations and warranties of such Lender contained in Section 2(c) of such Assignment
Agreement are incorporated herein by this reference.

82

 

          10.2 Expenses

          Whether or not the transactions contemplated hereby shall be consummated, Company agrees to
pay promptly after the presentation of invoices (i) all the actual and reasonable costs and
expenses of Administrative Agent in connection with the preparation of the Loan Documents and any
consents, amendments, waivers or other modifications thereto; (ii) all reasonable costs of
furnishing all opinions by counsel for Company (including any opinions requested by Lenders as to
any legal matters arising hereunder) and of Company’s performance of and compliance with all
agreements and conditions on its part to be performed or complied with under this Agreement and the
other Loan Documents including with respect to confirming compliance with environmental, insurance
and solvency requirements; (iii) the reasonable fees, expenses and disbursements of counsel to
Administrative Agent in connection with the negotiation, preparation, execution and administration
of the Loan Documents and any consents, amendments, waivers or other modifications thereto and any
other documents or matters requested by Company; (iv) all other actual and reasonable costs and
expenses incurred by Administrative Agent in connection with the syndication of the Commitments and
any due diligence investigation performed by Administrative Agent; provided that, without Company’s
written consent (not to be unreasonably withheld or delayed), Company shall not be responsible for
reimbursement of such costs, fees and expenses set forth in clauses (i) through (iv) above (other
than legal, consultants’ and other professional fees and expenses) in an aggregate amount in excess
of $50,000 and (v) after the occurrence of an Event of Default, all costs and expenses, including
reasonable attorneys’ fees and costs of settlement, incurred by Administrative Agent and Lenders in
enforcing any Obligations of or in collecting any payments due from any Loan Party hereunder or
under the other Loan Documents by reason of such Event of Default (including in connection with the
enforcement of the Subsidiary Guaranty) or in connection with any refinancing or restructuring of
the credit arrangements provided under this Agreement in the nature of a “work-out” or pursuant to
any insolvency or bankruptcy proceedings.

          10.3 Indemnity

          In addition to the payment of expenses pursuant to subsection 10.2, whether or not the
transactions contemplated hereby shall be consummated, Company agrees to defend (subject to
Indemnitees’ selection of counsel), indemnify, pay and hold harmless Agents and Lenders, and the
officers, directors, employees, trustee, agents and affiliates of Agents and Lenders (collectively
called the “Indemnitees”), from and against any and all Indemnified Liabilities (as hereinafter
defined); provided that Company shall not have any obligation to any Indemnitee hereunder with
respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise solely from
the gross negligence or willful misconduct of that Indemnitee as determined by a final judgment of
a court of competent jurisdiction.

          As used herein, “Indemnified Liabilities” means, collectively, any and all liabilities,
obligations, losses, damages (including natural resource damages), penalties, actions, judgments,
suits, claims (including Environmental Claims), costs, expenses and disbursements of any kind or
nature whatsoever (including the reasonable fees and disbursements of counsel for

83

 

Indemnitees in connection with any investigative, administrative or judicial proceeding
commenced or threatened by any Person, whether or not any such Indemnitee shall be designated as a
party or a potential party thereto, and any fees or expenses incurred by Indemnitees in enforcing
this indemnity), whether direct, indirect or consequential and whether based on any federal, state
or foreign laws, statutes, rules or regulations (including securities and commercial laws,
statutes, rules or regulations and Environmental Laws), on common law or equitable cause or on
contract or otherwise, that may be imposed on, incurred by, or asserted against any such
Indemnitee, in any manner relating to or arising out of (i) this Agreement or the other Loan
Documents or the transactions contemplated hereby or thereby (including Lenders’ agreement to make
the Loans hereunder or the use or intended use of the proceeds thereof or the use or intended use
of any thereof, or any enforcement of any of the Loan Documents (including the enforcement of the
Subsidiary Guaranty) or (ii) the statements contained in the commitment letter delivered by any
Lender to Company with respect thereto.

          To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in
this subsection 10.3 may be unenforceable in whole or in part because they are violative of any law
or public policy, Company shall contribute the maximum portion that it is permitted to pay and
satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities
incurred by Indemnitees or any of them.

          10.4 Set-Off

          In addition to any rights now or hereafter granted under applicable law and not by way of
limitation of any such rights, upon the occurrence and during the continuance of any Event of
Default each Lender is hereby authorized by Company at any time or from time to time, without
notice to Company or to any other Person, any such notice being hereby expressly waived, to set off
and to appropriate and to apply any and all deposits (general or special, including Indebtedness
evidenced by certificates of deposit, whether matured or unmatured, but not including trust
accounts) and any other Indebtedness at any time held or owing by that Lender to or for the credit
or the account of Company against and on account of the obligations and liabilities of Company to
that Lender under this Agreement and the other Loan Documents, including all claims of any nature
or description arising out of or connected with this Agreement or any other Loan Document, provided
that said obligations and liabilities shall then be due and payable (whether by acceleration or
otherwise).

          10.5 Ratable Sharing

          Lenders hereby agree among themselves that if any of them shall, whether by voluntary payment
(other than a voluntary prepayment of Loans made and applied in accordance with the terms of this
Agreement), by realization upon security, through the exercise of any right of set-off or banker’s
lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents
or otherwise, or as adequate protection of a deposit treated as cash collateral under the
Bankruptcy Code, receive payment or reduction of a proportion of the

84

 

aggregate amount of principal, interest, amounts payable in respect of fees and other amounts
owing to that Lender hereunder or under the other Loan Documents (collectively, the “Aggregate
Amounts Owing” to such Lender) which is greater than the proportion received by any other Lender in
respect of the Aggregate Amounts Owing to such other Lender, then the Lender receiving such
proportionately greater payment shall (i) notify Administrative Agent and each other Lender of the
receipt of such payment and (ii) apply a portion of such payment to purchase participations (which
it shall be deemed to have purchased from each seller of a participation simultaneously upon the
receipt by such seller of its portion of such payment) in the Aggregate Amounts Owing to the other
Lenders so that all such recoveries of Aggregate Amounts Owing shall be shared by all Lenders in
proportion to the Aggregate Amounts Owing to them; provided that if all or part of such
proportionately greater payment received by such purchasing Lender is thereafter recovered from
such Lender upon the bankruptcy or reorganization of Company or otherwise, those purchases shall be
rescinded and the purchase prices paid for such participations shall be returned to such purchasing
Lender ratably to the extent of such recovery, but without interest. Company expressly consents to
the foregoing arrangement and agrees that any holder of a participation so purchased may exercise
any and all rights of banker’s lien, set-off or counterclaim with respect to any and all monies
owing by Company to that holder with respect thereto as fully as if that holder were owed the
amount of the participation held by that holder.

          10.6 Amendments and Waivers

          A. No amendment, modification, termination or waiver of any provision of this Agreement or of
the Notes, and no consent to any departure by Company therefrom, shall in any event be effective
without the written concurrence of Requisite Lenders; provided that no amendment, modification,
termination, waiver or consent shall, without the written consent of each Lender directly and
adversely affected thereby, (i) reduce the principal amount of any of the Loans; (ii) postpone the
scheduled final maturity date of any of the Loans or the date on which any interest or any fees are
payable; (iii) decrease the interest rate borne by any of the Loans (other than any waiver of any
increase in the interest rate applicable to any of the Loans pursuant to subsection 2.2E or any
waiver or amendment to Section 7.4) or the amount of any fees payable to the Lenders hereunder; or
(iv) increase the maximum duration of Interest Periods permitted hereunder; provided, further, that
no such amendment, modification, termination, waiver or consent shall (i) increase the Commitments
of a Lender over the amount hereof then in effect, or extend the period of availability of the
Commitment of a Lender beyond the expiration date of its Commitment as provided by subsection 2.1A,
without the consent of such Lender, (ii) change in any manner the definition of “Requisite Lenders”
or the definition of “Pro Rata Share” without the written consent of each Lender, (iii) change in
any manner any provision of this Agreement which, by its terms, expressly requires the approval or
concurrence of all Lenders without the written consent of each Lender, (iv) release all or
substantially all the value of the Subsidiary Guaranty, in each case other than in accordance with
the terms of the Loan Documents, without the written consent of each Lender or (v) change in any
manner the provisions contained in subsection 8.1 or this subsection 10.6 without the written
consent of each Lender. In addition, (i) no amendment, modification, termination or waiver of any
provision of any Note shall be effective without the written concurrence of the Lender which is the
holder of that Note and (ii) no amendment, modification, termination or waiver of any provision of
Section

85

 

9 or of any other provision of this Agreement which, by its terms, expressly requires the
approval or concurrence of Administrative Agent shall be effective without the written concurrence
of Administrative Agent. Administrative Agent may, but shall have no obligation to, with the
concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of that
Lender. Any waiver or consent shall be effective only in the specific instance and for the
specific purpose for which it was given. No notice to or demand on Company in any case shall
entitle Company to any other or further notice or demand in similar or other circumstances. Any
amendment, modification, termination, waiver or consent effected in accordance with this subsection
10.6 shall be binding upon each Lender at the time outstanding, each future Lender and, if signed
by Company, on Company.

          B. Replacement of Lender. If, in connection with any proposed change, waiver, discharge or
termination to any of the provisions of this Agreement that requires the consent of each Lender or
each Lender affected thereby, the consent of the Requisite Lenders is obtained but the consent of
one or more of such other Lenders whose consent is required is not obtained, then Administrative
Agent shall have the right with the consent of Company, so long as all non-consenting Lenders whose
individual consent is required are treated as described in either clause (A) or (B) below, to
either (A) replace each such non-consenting Lender or Lenders with one or more Replacement Lenders
pursuant to subsection 2.8 so long as at the time of such replacement each outstanding Loan of each
such Lender being replaced is repaid in full (including accrued and unpaid interest or any fees or
other amounts then due and payable) and so long as each such Replacement Lender consents to the
proposed change, waiver, discharge or termination or (B) terminate such non-consenting Lender’s
Commitments and/or repay in full each outstanding Loan of such Lender, provided that, unless the
Commitments that are terminated, and Loans repaid, pursuant to preceding clause (B) are immediately
replaced in full at such time through the addition of new Lenders or the increase of the
Commitments and/or outstanding Loans of existing Lenders (who in each case must specifically
consent thereto), then in the case of any action pursuant to preceding clause (B) the Requisite
Lenders (determined after giving effect to the proposed action) shall specifically consent thereto;
provided, further, that in any event Administrative Agent shall not have the right to replace a
Lender, terminate its Commitments or repay its Loans solely as a result of the exercise of such
Lender’s rights (and the withholding of any required consent by such Lender) to refuse to increase
its Commitment over the amount then in effect pursuant to the second proviso contained in the first
sentence of subsection 10.6A.

          10.7 Independence of Covenants

          All covenants hereunder shall be given independent effect so that if a particular action or
condition is not permitted by any of such covenants, the fact that it would be permitted by an
exception to, or would otherwise be within the limitations of, another covenant shall not avoid the
occurrence of an Event of Default or Potential Event of Default if such action is taken or
condition exists.

86

 

          10.8 Notices

          Unless otherwise specifically provided herein, any notice or other communication herein
required or permitted to be given shall be in writing and may be personally served or sent by
telefacsimile or United States mail or courier service and shall be deemed to have been given when
delivered in person or by courier service, upon receipt of telefacsimile, or three Business Days
after depositing it in the United States mail with postage prepaid and properly addressed; provided
that notices to Agents shall not be effective until received; provided further, that Administrative
Agent may make all notices, requests, financial statements, financial and other reports,
certificates and other information materials, but excluding any such communication that (i) is or
relates to a borrowing request or a conversion/continuation notice, (ii) relates to the payment of
any principal or other amount due under this Agreement prior to the scheduled date therefor, (iii)
provides notice of any Potential Event of Default or Event of Default under this Agreement or any
other Loan Document or (iv) is required to be delivered to satisfy any condition precedent to the
effectiveness of this Agreement and/or the Borrowing (all such non-excluded communications being
referred to herein collectively as “Communications”) available to the Lenders by posting the
Communications on Intralinks or a substantially similar electronic transmission system. For the
purposes hereof, the address of each party hereto shall be as set forth under such party’s name on
the signature pages hereof or (i) as to Company and Administrative Agent, such other address as
shall be designated by such Person in a written notice delivered to the other parties hereto and
(ii) as to each other party, such other address as shall be designated by such party in a written
notice delivered to Administrative Agent.

          10.9 Survival of Representations, Warranties and Agreements

          A. All representations, warranties and agreements made herein shall survive the execution and
delivery of this Agreement and the making of the Loans.

          B. Notwithstanding anything in this Agreement or implied by law to the contrary, the
agreements of Company set forth in subsections 2.6D, 2.7, 10.2, 10.3 and 10.4 and the agreements of
Lenders set forth in subsections 9.2C, 9.4 and 10.5 shall to the extent set forth therein survive
the payment of the Loans and the termination of this Agreement.

          10.10 Failure or Indulgence Not Waiver; Remedies Cumulative

          No failure or delay on the part of Administrative Agent or any Lender in the exercise of any
power, right or privilege hereunder or under any other Loan Document shall impair such power, right
or privilege or be construed to be a waiver of any default or acquiescence therein, nor shall any
single or partial exercise of any such power, right or privilege preclude other or further exercise
thereof or of any other power, right or privilege. All rights and remedies existing under this
Agreement and the other Loan Documents are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

87

 

          10.11 Marshalling; Payments Set Aside

          Neither Administrative Agent nor any Lender shall be under any obligation to marshal any
assets in favor of Company or any other party or against or in payment of any or all of the
Obligations. To the extent that Company makes a payment or payments to Administrative Agent or
Lenders (or to Administrative Agent for the benefit of Lenders), or Administrative Agent or Lenders
enforce any security interests or exercise their rights of set-off, and such payment or payments or
the proceeds of such enforcement or set-off or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee,
receiver or any other party under any bankruptcy law, any other state or federal law, common law or
any equitable cause, then, to the extent of such recovery, the obligation or part thereof
originally intended to be satisfied, and all Liens, rights and remedies therefor or related
thereto, shall be revived and continued in full force and effect as if such payment or payments had
not been made or such enforcement or setoff had not occurred.

          10.12 Severability

          In case any provision in or obligation under this Agreement or the Notes shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the
remaining provisions or obligations, or of such provision or obligation in any other jurisdiction,
shall not in any way be affected or impaired thereby.

          10.13 Obligations Several; Independent Nature of Lenders’ Rights

          The obligations of Lenders hereunder are several and no Lender shall be responsible for the
obligations or Commitments of any other Lender hereunder. Nothing contained herein or in any other
Loan Document, and no action taken by Lenders pursuant hereto or thereto, shall be deemed to
constitute Lenders as a partnership, an association, a joint venture or any other kind of entity.
The amounts payable at any time hereunder to each Lender shall be a separate and independent debt,
and each Lender shall be entitled to protect and enforce its rights arising out of this Agreement
and it shall not be necessary for any other Lender to be joined as an additional party in any
proceeding for such purpose.

          10.14 Headings

          Section and subsection headings in this Agreement are included herein for convenience of
reference only and shall not constitute a part of this Agreement for any other purpose or be given
any substantive effect.

          10.15 Applicable Law

88

 

          THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY,
AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK.

          10.16 Successors and Assigns

          This Agreement shall be binding upon the parties hereto and their respective successors and
assigns and shall inure to the benefit of the parties hereto and the successors and assigns of
Lenders (it being understood that Lenders’ rights of assignment are subject to subsection 10.1).
Neither Company’s rights or obligations hereunder nor any interest therein may be assigned or
delegated by Company without the prior written consent of all Lenders.

          10.17 CONSENT TO JURISDICTION AND SERVICE OF PROCESS

          ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST COMPANY ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT, OR ANY OBLIGATIONS THEREUNDER, MAY BE BROUGHT IN ANY STATE OR FEDERAL
COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK. BY EXECUTING AND
DELIVERING THIS AGREEMENT, COMPANY, FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, IRREVOCABLY

               (i) ACCEPTS GENERALLY AND UNCONDITIONALLY THE NONEXCLUSIVE JURISDICTION AND VENUE OF
SUCH COURTS;

               (ii) WAIVES ANY DEFENSE OF FORUM NON CONVENIENS WITH RESPECT TO ANY STATE OR FEDERAL
COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK;

               (iii) AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDING IN ANY SUCH COURT MAY
BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED, TO COMPANY AT ITS
ADDRESS PROVIDED IN ACCORDANCE WITH SUBSECTION 10.8;

               (iv) AGREES THAT SERVICE AS PROVIDED IN CLAUSE (iii) ABOVE IS SUFFICIENT TO CONFER
PERSONAL JURISDICTION OVER COMPANY IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE
CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT;

89

 

               (v) AGREES THAT LENDERS RETAIN THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST COMPANY IN THE COURTS OF ANY OTHER
JURISDICTION; AND

               (vi) AGREES THAT THE PROVISIONS OF THIS SUBSECTION 10.17 RELATING TO JURISDICTION AND
VENUE SHALL BE BINDING AND ENFORCEABLE TO THE FULLEST EXTENT PERMISSIBLE UNDER NEW YORK
GENERAL OBLIGATIONS LAW SECTION 5-1402 OR OTHERWISE.

          10.18 WAIVER OF JURY TRIAL

          EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY
TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE
OTHER LOAN DOCUMENTS OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN
TRANSACTION OR THE LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED. The scope of this
waiver is intended to be all-encompassing of any and all disputes that may be filed in any court
and that relate to the subject matter of this transaction, including contract claims, tort claims,
breach of duty claims and all other common law and statutory claims. Each party hereto
acknowledges that this waiver is a material inducement to enter into a business relationship, that
each has already relied on this waiver in entering into this Agreement, and that each will continue
to rely on this waiver in their related future dealings. Each party hereto further warrants and
represents that it has reviewed this waiver with its legal counsel and that it knowingly and
voluntarily waives its jury trial rights following consultation with legal counsel. THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING (OTHER THAN BY A
MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SUBSECTION 10.18 AND EXECUTED BY EACH OF THE
PARTIES HERETO), AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY OTHER DOCUMENTS OR
AGREEMENTS RELATING TO THE LOANS MADE HEREUNDER. In the event of litigation, this Agreement may be
filed as a written consent to a trial by the court.

          10.19 Confidentiality

          Each Lender shall hold all non-public information obtained pursuant to the requirements of
this Agreement which has been identified as confidential by Company in accordance with such
Lender’s customary procedures for handling confidential information of this nature and in
accordance with safe and sound banking practices, if applicable, it being understood and agreed by
Company that in any event a Lender may make disclosures to the

90

 

accountants, auditors, attorneys, and Affiliates of such Lender or disclosures reasonably
required by any bona fide assignee, transferee or participant or to any actual or prospective
contractual counterparty (or its advisor) to any securitization, hedge or other derivative
transaction in connection with the contemplated assignment or transfer by such Lender of any Loans
or any participations therein or disclosures required or requested by any governmental agency or
representative thereof or pursuant to legal process; provided that, in each of the foregoing cases,
the Person to which disclosure is to be made is informed of the confidential nature of such
information and agrees to maintain its confidentiality; provided, further, that, unless
specifically prohibited by applicable law or court order, each Lender shall notify Company of any
request by any governmental agency or representative thereof (other than any such request in
connection with any routine compliance examination or examination of the financial condition of
such Lender by such governmental agency) for disclosure of any such non-public information prior to
disclosure of such information; and provided, further, that in no event shall any Lender be
obligated or required to return any materials furnished by Company or any of its Subsidiaries. Any
Person required to maintain the confidentiality of information as provided in this subsection shall
be considered to have complied with its obligation to do so if such Person has exercised the same
degree of care to maintain the confidentiality of such information as such person would accord to
its own confidential information.

          10.20 Counterparts; Effectiveness

          This Agreement and any amendments, waivers, consents or supplements hereto or in connection
herewith may be executed in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument; signature pages may be
detached from multiple separate counterparts and attached to a single counterpart so that all
signature pages are physically attached to the same document. This Agreement shall become

Company and Administrative Agent of written or telephonic notification of such execution and
authorization of delivery thereof. Delivery of an executed counterpart of a signature page of this
Agreement by telefacsimile or electronic transmission (in PDF format) shall be effective as

OPTION AGREEMENT

UNDER THE

ALLIED WORLD ASSURANCE COMPANY HOLDINGS, AG

THIRD AMENDED AND RESTATED 2001 EMPLOYEE STOCK OPTION PLAN

          Pursuant to the Option Grant Notice (the “Grant Notice”) delivered to Holder (as
defined in the Grant Notice), and subject to the terms of this Option Agreement (this “Option
Agreement”) and the Allied World Assurance Company Holdings, AG, Third Amended and Restated
2001 Employee Stock Option Plan (the “Plan”), Allied World Assurance Company Holdings, AG
(the “Company”) and Holder agree as follows. Capitalized terms not otherwise defined
herein shall have the same meaning as set forth in the Plan.

     1. Grant of Option. Subject to the terms and conditions set forth herein and in the
Plan, the Company hereby grants to Holder options to purchase up to the number of Common Shares
provided in the Grant Notice, at an exercise price per share as provided in the Grant Notice (the
“Options”). The Company may make one or more additional grants of options to Holder under
this Option Agreement by providing Holder with a new Grant Notice, which may also include any terms
and conditions differing from this Option Agreement. The Company reserves all rights with respect
to the granting of additional options hereunder and makes no implied promise to grant additional
options.

     2. Vesting. Subject to the limitations contained herein, the Options shall vest as
provided in the Grant Notice; provided, however, that, except as may otherwise be provided in any
employment agreement between the Company and Holder that is effective immediately prior to Holder’s
termination of employment or service, all vesting shall cease upon Holder’s termination of
employment or service, as applicable, with the Company.

     3. Exercise of Options Following Termination of Employment or Service.

          The provisions of Section 7(c) of the Plan are incorporated herein by reference and made a
part hereof.

     4. Method of Exercising Options. The Options may be exercised by the delivery of
notice of the number of Common Shares with respect to which the Options are being exercised
accompanied by payment in full of the purchase price of such shares. Such notice shall be
delivered either (x) in writing to the Company at its principal office or at such other address as
may be established by the Committee, to the attention of the Company Secretary; or (y) to a
third-party stock plan administrator as may be arranged for by the Company or the Committee from
time to time for purposes of the administration of outstanding Options under the Plan, in either
case of (x) or (y), as communicated to the Holder in a manner consistent with the terms of Section
10 hereof. Payment for such shares may be made (a) in immediately available funds in United States
dollars, by certified or bank cashier’s check or wire transfer payable to the Company or
third-party administrator, as applicable; (b) through a broker-assisted cashless exercise program
established by the third-party stock plan administrator; or (c) by any other means approved by the
Committee. Anything herein to the contrary notwithstanding, the Company shall not directly or
indirectly extend or maintain credit, or arrange for the extension of credit, in the form of a
personal loan to or for any director or executive officer of the Company

 

 

through the Plan in violation of Section 402 of the Sarbanes-Oxley Act of 2002 (“Section
402 of SOX”), and to the extent that any form of payment would, in the opinion of the Company’s
counsel, result in a violation of Section 402 of SOX, such form of payment shall not be available.

     5. Issuance of Shares. If Holder elects to receive Common Shares after exercise of an
Option, then as promptly as practical after receipt of such notification and full payment of such
purchase price and any required income tax withholding amount (as provided in Section 9 hereof),
the Company shall issue or transfer, or cause such issue or transfer, to Holder the number of
shares with respect to which the Options have been so exercised, and shall either (a) deliver, or
cause to be delivered, to Holder a certificate or certificates therefor, registered in Holder’s
name or (b) cause such shares to be credited to Holder’s account at the third-party stock plan
administrator.

     6. Company; Holder.

          (a) The term “Company” as used in this Agreement with reference to employment shall include
the Company and its subsidiaries.

          (b) Whenever the word “Holder” is used in any provision of this Agreement under circumstances
where the provision should logically be construed to apply to the executors, the administrators, or
the person or persons to whom the Options may be transferred by will or by the laws of descent and
distribution, the word “Holder” shall be deemed to include such person or persons.

     7. Non-Transferability. The Options are not transferable by Holder except (a) by will
or the laws of descent and distribution, to the Company; (b) to or for the benefit of any spouse,
child or grandchild of Holder; or (c) to a trust or partnership for the benefit of any of the
foregoing. Except as otherwise provided herein, no assignment or transfer of the Options, or of
the rights represented thereby, whether voluntary or involuntary, by operation of law or otherwise,
shall vest in the assignee or transferee any interest or right herein whatsoever, but immediately
upon such assignment or transfer the Options shall terminate and become of no further effect.

     8. Rights as Shareholder. Holder or a transferee of the Options shall have no rights
as a shareholder with respect to any share covered by the Options until Holder shall have become
the holder of record or the beneficial owner of such share, and no adjustment shall be made for
dividends or distributions or other rights in respect of such share for which the record date is
prior to the date upon which Holder shall become the holder of record or the beneficial owner
thereof.

     9. Tax Withholding. The provisions of Section 12 of the Plan are incorporated herein
by reference and made a part hereof.

     10. Notice. Every notice or other communication relating to this Agreement between
the Company and Holder shall be in writing, and shall be mailed to or delivered to the party for
whom it is intended at such address as may from time to time be designated by it in a notice mailed
or delivered to the other party as herein provided, provided that, unless and until some other
address be so designated, all notices or communications by Holder to the Company shall be

-2-

 

mailed or delivered to the Company at its principal executive office, to the attention of the
Company Secretary, and all notices or communications by the Company to Holder may be given to
Holder personally or may be mailed to Holder at Holder’s last known address, as reflected in the
Company’s records. Notwithstanding the above, all notices and communications between the Holder
and any third-party stock plan administrator shall be mailed, delivered, transmitted or sent in
accordance with the procedures established by such third-party stock plan administrator and
communicated to Holder from time to time.

     11. No Right to Continued Service. This Agreement does not confer upon Holder any
right to continue as an employee or service provided to the Company.

     12. Binding Effect. This Agreement shall be binding upon the heirs, executors,
administrators and successors of the parties hereto.

     13. Waiver and Amendments. Any waiver, alteration, amendment or modification of any
of the terms of this Agreement shall be valid only if made in writing and signed by the parties
hereto; provided, however, that any such waiver, alteration, amendment or modification is consented
to on the Company’s behalf by the Committee. No waiver by either of the parties hereto of their
rights hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences
or transactions hereunder unless such waiver specifically states that it is to be construed as a
continuing waiver.

     14. Governing Law. This Agreement shall be construed and interpreted in accordance
with the laws of the State of New York, without regard to the principles of conflicts of law
thereof. Notwithstanding anything contained in this Option Agreement, the Grant Notice or the Plan
to the contrary, if any suit or claim is instituted by Holder or the Company relating to this
Option Agreement, the Grant Notice or the Plan, Holder hereby submits to the exclusive jurisdiction
of and venue in the courts of Switzerland.

     15. Plan. The terms and provisions of the Plan are incorporated herein by reference.
Capitalized terms used herein which are not defined herein shall have the meanings attributable
thereto in the Plan. In the event of a conflict or inconsistency between the terms and provisions
of the Plan and the provisions of this Agreement, the Plan shall govern and control.
