     The Applicable Facility Fee Rate will be determined based upon the two highest ratings issued
by S&P, Moody’s and Fitch. If such two highest ratings differ (i) by one rating, the higher of
such two highest ratings will apply to determine the Applicable Facility Fee Rate so long as the
higher rating is from either S&P or Moody’s, otherwise the lower of such two highest ratings will
apply, (ii) by two ratings, the rating which falls between such two highest ratings will apply to
determine the Applicable Facility Fee Rate, or (iii) by more than two ratings, the rating which is
one level above the lower of such two highest ratings will apply to determine the Applicable
Facility Fee Rate. If only one such rating is issued by S&P, Moody’s or Fitch, the Applicable
Facility Fee Rate will be determined by such rating. The Company shall give written notice to the
Administrative Agent of any changes to such ratings, within three (3) Business Days thereof, and
any change to the Applicable Facility Fee Rate shall be effective on the date of the relevant
change. Notwithstanding the foregoing, if the Company shall at any time fail to have in effect at
least one such rating on the Company’s non-credit enhanced senior unsecured long-term debt, the
Company shall seek and obtain (if not already in effect), within thirty (30) days after such rating
first ceases to be in effect, a corporate credit rating or a bank loan rating from Fitch, Moody’s
and/or S&P (or if none of Fitch, Moody’s and S&P issue such types of ratings or ratings comparable
thereto, from another nationally recognized rating agency approved by each of the Company and the
Administrative Agent), and the Applicable Facility Fee Rate shall thereafter be based on such
ratings in the same manner as provided herein with respect to the Company’s non-credit enhanced
senior unsecured long-term debt rating (with the Applicable Facility Fee Rate in effect prior to
the issuance of such corporate credit rating or bank loan rating being the same as the Applicable
Facility Fee Rate in effect at the time the non-credit enhanced senior unsecured long-term debt
rating ceases to be in effect).

     “Applicable Margin” means, for any day, at such times as a rating (either express or implied)
by S&P, Moody’s or Fitch is in effect on the Company’s non-credit enhanced senior unsecured
long-term debt, the percentage per annum set forth opposite such debt rating:

	 	 	 	 	 	 	 	 	 
	 	 	Percentage
	 	 	 	 	 	 	LIBOR Rate and
	Debt
Rating (S&P and Fitch/Moody’s)	 	Base Rate	 	Letter of Credit Fee Rate
	A+/A1 or above
	 	 	0.000	%	 	 	0.775	%
	A/A2
	 	 	0.000	%	 	 	0.875	%
	A-/A3
	 	 	0.100	%	 	 	1.100	%
	BBB+/Baa1
	 	 	0.300	%	 	 	1.300	%
	BBB/Baa2 or below
	 	 	0.500	%	 	 	1.500	%

     The Applicable Margin will be determined based upon the two highest ratings issued by S&P,
Moody’s and Fitch. If such two highest ratings differ (i) by one rating, the higher of such two
highest ratings will apply to determine the Applicable Margin so long as the higher rating is from
either S&P or Moody’s, otherwise the lower of such two highest ratings will apply, (ii) by two
ratings, the rating which falls between such two highest ratings will apply to determine the
Applicable Margin, or (iii) by more than two ratings, the rating which is one level above the

[Revolving Credit Agreement]

3

 

lower of such two highest ratings will apply to determine the Applicable Margin. If only one
such rating is issued by S&P, Moody’s or Fitch, the Applicable Margin will be determined by such
rating. The Company shall give written notice to the Administrative Agent of any changes to such
ratings, within three (3) Business Days thereof, and any change to the Applicable Margin shall be
effective on the date of the relevant change. Notwithstanding the foregoing, if the Company shall
at any time fail to have in effect any such rating on the Company’s non-credit enhanced senior
unsecured long-term debt, the Company shall seek and obtain (if not already in effect), within
thirty (30) days after such rating first ceases to be in effect, a corporate credit rating or a
bank loan rating from Fitch, Moody’s and/or S&P (or if none of Fitch, Moody’s and S&P issue such
types of ratings or ratings comparable thereto, from another nationally recognized rating agency
approved by each of the Company and the Administrative Agent), and the Applicable Margin shall
thereafter be based on such ratings in the same manner as provided herein with respect to the
Company’s non-credit enhanced senior unsecured long-term debt rating (with the Applicable Margin in
effect prior to the issuance of such corporate credit rating or bank loan rating being the same as
the Applicable Margin in effect at the time the non-credit enhanced senior unsecured long-term debt
rating ceases to be in effect).

Lender on loans to any of its customers), with any change in the Base Rate resulting from a change
in such announced rate to be effective on the date of the relevant change;

          (ii) the sum of (x) the rate per annum equal to the weighted average of the rates on overnight

any Specified Currency (with a copy of any such notice to be sent simultaneously to the Sub-Agent),
or (D) the day such Reimbursement Obligation becomes due, as the case may be, that it intends to
repay such Borrowing or Reimbursement Obligation, the Company shall be deemed to have requested for
such Borrower, as applicable, (x) the continuation of such Borrowing as a Eurocurrency Loan with an
Interest Period of one (1) month or (y) the advance of a new Borrowing of Base Rate Loans (after
converting, if necessary, the Reimbursement Obligation into Dollars using the applicable Exchange

which Borrowing pursuant to this clause (y) shall be deemed to have been funded on such date by the
Lenders in accordance with Section 2.3(a) and to have been applied on such day to pay the
Reimbursement Obligation then due, in each case so long as no Event of Default shall have occurred
and be continuing or would occur as a result of such Borrowing but otherwise disregarding the
conditions to Borrowings set forth in Section 4.2. Upon the occurrence and during the continuance
of any Event of Default, and upon notice thereof from the Administrative Agent to the Company (i)

therefor, convert into a Base Rate Loan, and (ii) the obligation of the Lenders to fund Loans in

continue or convert Loans into Eurocurrency Loans shall be suspended.

          (f) Conversion. If the Company shall elect to convert any particular Borrowing

of this sentence) be deemed to instead constitute two Borrowings (each originally advanced on the
same date as such particular Borrowing), one comprised of (subject to subsequent conversion in
accordance with this Agreement) Eurocurrency Loans in an aggregate principal amount equal to the
portion of such Borrowing so elected by the Company to be comprised of Eurocurrency Loans and the
second comprised of (subject to subsequent conversion in accordance with this Agreement) Base Rate
Loans in an aggregate principal amount equal to the portion of such particular Borrowing so elected
by the Company to be comprised of Base Rate Loans. If the Company shall elect to have multiple
Interest Periods apply to any such particular Borrowing comprised of Eurocurrency Loans, then, from
and after the date such multiple Interest Periods commence, such particular Borrowing shall, for
all purposes of this Agreement (including, without limitation, for purposes of subsequent
application of this sentence), be deemed to constitute a number of separate Borrowings (each
originally commencing on the same date as such particular Borrowing) equal to the number of, and
corresponding to, the different Interest Periods so selected, each such deemed separate Borrowing
corresponding to a particular selected Interest Period comprised of (subject to subsequent
conversion in accordance with this Agreement) Eurocurrency Loans in an aggregate principal amount
equal to the portion of such particular Borrowing so elected by the Company to have such Interest
Period. This Section 2.3(f) shall be applied appropriately in the event that the Company shall
make the elections described in the two preceding sentences at the same time with respect to the
same particular Borrowing.

Termination Date;

               (ii) whenever the last day of any Interest Period would otherwise be a day that is not a

succeeding Business Day, or (ii) in the case of Eurocurrency Loans only, reduced to the immediately
preceding Business Day if the next succeeding Business Day is in the next calendar month; and

               (iii) for purposes of determining an Interest Period, a month means a period starting on one
day in a calendar month and ending on the numerically corresponding day in the next calendar month;
provided, however, that if there is no such numerically corresponding day in the month in which an

month, then in the case of Eurocurrency Loans only, such Interest Period shall end on the last

applicable Borrower in the manner described in the preceding sentence (and if such credit is made
on the next Business Day, with interest on such amount to begin accruing hereunder on such next
Business Day); provided that acceptance by any Borrower of any such late amount shall not be deemed
a waiver by the Company of any rights it may have against such Lender. No Lender shall be
responsible to any Borrower for any failure by another

[Revolving Credit Agreement]

25

 

Lender to fund its portion of a Borrowing, and no such failure by a Lender shall relieve any
other Lender from its obligation, if any, to fund its portion of a Borrowing.

          (b) Administrative Agent Reliance on Lender Funding. Unless the Administrative Agent
shall have been notified by a Lender prior to the time at which such Lender is scheduled to make
payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon
receipt) that such Lender does not intend to make such payment, the Administrative Agent may assume
that such Lender has made such payment when due and in reliance upon such assumption may (but shall
not be required to) make available to the applicable Borrower the proceeds of the Loan to be made
by such Lender and, if any Lender has not in fact made such payment to the Administrative Agent,
such Lender shall, on demand, pay to the Administrative Agent the amount made available to the
applicable Borrower attributable to such Lender together with interest thereon for each day during
the period commencing on the date such amount was made available to the applicable Borrower and
ending on (but excluding) the date such Lender pays such amount to the Administrative Agent at a
rate per annum equal to the Administrative Agent’s cost of funds for such amount. If such amount
is not received from such Lender by the Administrative Agent immediately upon demand, the
applicable Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan
attributable to such Lender with interest thereon at a rate per annum equal to the interest rate
applicable to the relevant Loan, but the applicable Borrower will in no event be liable to pay any
amounts otherwise due pursuant to Section 2.11 in respect of such repayment. Nothing in this
subsection shall be deemed to relieve any Lender from any obligation to fund any Loans hereunder or
to prejudice any rights which any Borrower may have against any Lender as a result of any default
by such Lender hereunder.

          Section 2.6. Applicable Interest Rates.

          (a) Base Rate Loans. Each Base Rate Loan shall bear interest (computed on the basis
of a 365-day year or 366-day year, as the case may be, and actual days elapsed including the first
day but excluding the date of repayment) on the unpaid principal amount thereof from the date such
Loan is made until maturity (whether by acceleration or otherwise) or conversion to a Eurocurrency
Loan, at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii) the Base Rate
from time to time in effect plus the Applicable Margin. Each Borrower agrees to pay such interest
on each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise).

          (b) Eurocurrency Loans. Each Eurocurrency Loan shall bear interest (computed on the
basis of a 360-day year and actual days elapsed, except with respect to Eurocurrency Loans funded
in Pounds, in which case interest will be computed on the basis of a 365-day year or 366-day year,
as the case may be, and actual days elapsed, in each case including the first day but excluding the
date of repayment) on the unpaid principal amount thereof from the date such Loan is made until
maturity (whether by acceleration or otherwise) or, in the case of Eurocurrency Loans, conversion
to a Base Rate Loan at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii)
the sum of Adjusted LIBOR plus the Applicable Margin. Each Borrower agrees to pay such interest on
each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise) or,
in the case of Eurocurrency Loans, conversion to a Base Rate Loan.

[Revolving Credit Agreement]

26

 

          (c) Swingline Loans. Each Swingline Loan shall bear interest (computed on the basis
of a 365-day year or 366-day year, as the case may be, and actual days elapsed including the first
day but excluding the date of repayment) on the unpaid principal amount thereof from the date such
Loan is made until maturity (whether by acceleration or otherwise) at a rate per annum equal to the
lesser of (i) the Highest Lawful Rate, or (ii) the Base Rate from time to time in effect. Each
Borrower agrees to pay such interest on each Interest Payment Date for such Loan and at maturity
(whether by acceleration or otherwise).

          (d) Rate Determinations. The Administrative Agent shall determine each interest rate
applicable to the Loans and Reimbursement Obligations hereunder insofar as such interest rate
involves a determination of Base Rate, Adjusted LIBOR or LIBOR Rate, or any applicable default rate
pursuant to Section 2.7, and such determination shall be conclusive and binding except in the case
of the Administrative Agent’s manifest error or willful misconduct. The Administrative Agent shall
promptly give notice to the Company and each Lender of each determination of Adjusted LIBOR, with
respect to each Eurocurrency Loan.

          Section 2.7. Default Rate. If any payment of principal on any Loan is not made when due after the
expiration of the grace period therefor provided in Section 7.1(a) (whether by acceleration or
otherwise), or any Reimbursement Obligation is not paid when due as provided in Section 2.12(c),
such past due Loan or Reimbursement Obligation shall bear interest (computed on the basis of a year
of 360, 365 or 366 days, as applicable, and actual days elapsed) after any such grace period
expires until such principal then due is paid in full, which each Borrower agrees to pay on demand,
at a rate per annum equal to:

          (a) for any Base Rate Loan or any Swingline Loan, the lesser of (i) the Highest Lawful Rate,
or (ii) the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but
not less than the Base Rate in effect at the time such payment was due);

          (b) for any Eurocurrency Loan, the lesser of (i) the Highest Lawful Rate, or (ii) the sum of
two percent (2%) per annum plus the rate of interest in effect thereon at the time of such default
until the end of the Interest Period for such Loan and, thereafter, at a rate per annum equal to
the sum of two percent (2%) per annum plus (x) in the case of any Loans made in Dollars, the Base
Rate from time to time in effect (but not less than the Base Rate in effect at the time such
payment was due), or (y) in the case of any Loans made in Euros, Pounds, Australian Dollars,
Canadian Dollars, Singapore Dollars or Kroner, the interest rate that would otherwise then be
applicable under this Agreement to a Eurocurrency Loan made in such currency for an Interest Period
of one month as from time to time in effect (but not less than such interest rate in effect at the
time such payment was due); and

          (c) for any unpaid Reimbursement Obligations, the lesser of (i) the Highest Lawful Rate, or
(ii) the sum of two percent (2%) per annum plus (x) in the case of any Reimbursement Obligations
payable in Dollars, the Base Rate from time to time in effect (but not less than the Base Rate in
effect at the time such payment was due), or (y) in the case of any Reimbursement Obligations
payable in any currency other than Dollars, the interest rate that would otherwise then be
applicable under this Agreement to a Eurocurrency Loan made in such

[Revolving Credit Agreement]

27

 

currency for an Interest Period of one month as from time to time in effect (but not less than
such interest rate in effect at the time such payment was due).

          It is the intention of the Administrative Agent and the Lenders to conform strictly to usury
laws applicable to them. Accordingly, if the transactions contemplated hereby or any Loan or other
Obligation would be usurious as to any of the Lenders under laws applicable to it (including the
laws of the United States of America and the State of New York or any other jurisdiction whose laws
may be mandatorily applicable to such Lender notwithstanding the other provisions of this
Agreement, the Notes or any other Credit Document), then, in that event, notwithstanding anything
to the contrary in this Agreement, the Notes or any other Credit Document, it is agreed as follows:
(i) the aggregate of all consideration which constitutes interest under laws applicable to such
Lender that is contracted for, taken, reserved, charged or received by such Lender under this
Agreement, the Notes or any other Credit Document or otherwise shall under no circumstances exceed
the Highest Lawful Rate, and any excess shall be credited by such Lender on the principal amount of
the Loans or to the Reimbursement Obligations (or, if the principal amount of the Loans and all
Reimbursement Obligations shall have been paid in full, refunded by such Lender to the applicable
Borrower); and (ii) in the event that the maturity of the Loans is accelerated by reason of an
election of the holder or holders thereof resulting from any Event of Default hereunder or
otherwise, or in the event of any required or permitted prepayment, then such consideration that
constitutes interest under laws applicable to such Lender may never include more than the Highest
Lawful Rate, and excess interest, if any, provided for in this Agreement, the Notes, any other
Credit Document or otherwise shall be automatically canceled by such Lender as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the
principal amount of the Loans or to the Reimbursement Obligations (or if the principal amount of
the Loans and all Reimbursement Obligations shall have been paid in full, refunded by such Lender
to the applicable Borrower).

          Section 2.8. Repayment of Loans; Evidence of Debt.

          (a) Repayment of Loans. Each Borrower hereby unconditionally promises to pay to the
Administrative Agent, for the account of each Lender, on the Commitment Termination Date, the
unpaid amount of each Revolving Loan made by such Lender to such Borrower then outstanding. Each
Borrower hereby unconditionally promises to pay to the Swingline Lender the unpaid principal amount
of each Swingline Loan to such Borrower no later than the Commitment Termination Date.

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

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

[Revolving Credit Agreement]

28

 

each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder for the account of the Lenders and each Lender’s share thereof.

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

          (e) Notes. The Revolving Loans outstanding to each Borrower from each Lender shall,
at the written request of such Lender, be evidenced by a promissory note of the applicable Borrower
payable to such Lender in the form of Exhibit 2.8A (each a “Revolving Note”) or, if such
Lender so requests in writing, by one or more individual promissory notes of such Borrower in
similar form but payable in the specific foreign currencies in which the Loans may be funded. Each
Borrower agrees to execute and deliver to the Administrative Agent, for the benefit of each Lender
requesting one or more promissory notes as aforesaid, an original of each such promissory note,
appropriately completed, to evidence the respective Loans made by such Lender to such Borrower
hereunder, within ten (10) Business Days after the Company receives a written request therefor.
The Swingline Loans outstanding to each Borrower shall be evidenced by a promissory note of each
Borrower payable to the Swingline Lender in the form of Exhibit 2.8B (a “Swingline Note”).

          (f) Recording of Loans and Payments on Notes. Each holder of a Note shall record on
its books and records or on a schedule to its appropriate Note (and prior to any transfer of its
Notes shall endorse thereon or on schedules forming a part thereof appropriate notations to
evidence) the amount of each Loan outstanding from it to the maker thereof, all payments of
principal and interest and the principal balance from time to time outstanding thereon, the Type of
such Loan and, if a Eurocurrency Loan the Interest Period and interest rate applicable thereto.
Such record, whether shown on the books and records of a holder of a Note or on a schedule to its
Note, shall be prima facie evidence as to all such matters; provided, however, that the failure of
any holder to record any of the foregoing or any error in any such record shall not limit or
otherwise affect the obligation of each Borrower to repay all Loans outstanding to such Borrower
hereunder together with accrued interest thereon. At the request of any holder of a Note and upon
such holder tendering to the applicable Borrower the Note to be replaced, the applicable Borrower
shall furnish a new Note to such holder to replace any outstanding Note and at such time the first
notation appearing on the schedule on the reverse side of, or attached to, such new Note shall set
forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

          Section 2.9. Optional Prepayments. Each Borrower shall have the privilege of prepaying any Base Rate
Loans or Swingline Loans without premium or penalty at any time in whole or at any time and from
time to time in part (but, if in part, then in an amount which is equal to or greater than
$1,000,000); provided, however, that the Company shall have given notice of such prepayment to the
Administrative Agent no later than 12:00 P.M. on the date of such prepayment. Each Borrower shall
have the privilege of prepaying any Adjusted LIBOR Loans (a) without premium or penalty in whole or
in part (but, if in part, then in an amount

[Revolving Credit Agreement]

29

 

which is equal to or greater than the Dollar Equivalent of $5,000,000 and in an integral multiple
of the Borrowing Multiple or such smaller amount as needed to prepay a particular Borrowing in
full) only on the last Business Day of an Interest Period for such Loan, and (b) at any other time
without premium or penalty except for the breakage fees and funding losses that are required to be
paid pursuant to Section 2.11; provided, however, that the Company shall have given notice of such
prepayment to the Administrative Agent no later than 12:00 P.M. at least three (3) Business Days
before the last Business Day of such Interest Period or the proposed prepayment date (or such
shorter period as may be agreed by the Administrative Agent in its sole discretion); provided,
further, that such notice may be conditioned upon the effectiveness of other credit facilities or
the closing of one or more securities offerings, in which case such notice shall be deemed
rescinded if such condition shall fail to be satisfied by the proposed effective date of such
prepayment and; provided, further, that upon any such rescission such Borrower shall be liable for
any breakage fees and funding losses that are required to be paid pursuant to Section 2.11. Any
such prepayments shall be made by the payment of the principal amount to be prepaid and accrued and
unpaid interest thereon to the date of such prepayment. Optional prepayments shall be applied to
the Obligations then outstanding in the order specified by the Company.

          Section 2.10. Mandatory Prepayments of Loans. In the event and on each occasion that the Dollar
Equivalent of the aggregate principal amount of outstanding Revolving Loans and L/C Obligations
exceeds the Revolving Credit Commitment Amount then in effect, then the Company or the Designated
Borrower, as appropriate, shall promptly prepay Revolving Loans in an aggregate amount sufficient
to eliminate such excess. Immediately upon determining the need to make any such prepayment, the
Company shall notify the Administrative Agent of such required prepayment and of the identity of
the particular Revolving Loans being prepaid. If the Administrative Agent shall notify the Company
that the Administrative Agent has determined that any prepayment is required under this Section
2.10, the Company or the Designated Borrower, as appropriate, shall make such prepayment no later
than the second Business Day following such notice. Any mandatory prepayment of Revolving Loans
pursuant hereto shall not be limited by the notice provision for prepayments set forth in Section
2.9. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on
the Loans prepaid and any applicable breakage fees and funding losses pursuant to Section 2.11.

          Section 2.11. Breakage Fees. If any Lender incurs any loss, cost or expense (excluding loss of
anticipated profits and other indirect or consequential damages) by reason of the liquidation or
re-employment of deposits or other funds acquired by such Lender to fund or maintain any
Eurocurrency Loan as a result of any of the following events other than any such occurrence as a
result of a change of circumstance described in Sections 8.1 or 8.2:

          (a) any payment, prepayment or conversion of any such Loan on a date other than the last day
of its Interest Period (whether by acceleration, mandatory prepayment or otherwise);

          (b) any failure to make a principal payment of any such Loan on the due date therefor; or

[Revolving Credit Agreement]

30

 

          (c) any failure by any Borrower to borrow, continue or prepay, or convert to, any such Loan on
the date specified in a notice given pursuant to Section 2.3 (other than by reason of a default of
such Lender),

then the applicable Borrower shall pay to such Lender such amount as will reimburse such Lender for
such loss, cost or expense. If any Lender makes such a claim for compensation, it shall provide to
the Company a certificate executed by an officer of such Lender setting forth the amount of such
loss, cost or expense in reasonable detail (including an explanation of the basis for and the
computation of such loss, cost or expense) no later than ninety (90) days after the event giving
rise to the claim for compensation, and the amounts shown on such certificate shall be prima facie
evidence of such Lender’s entitlement thereto. Within ten (10) days of receipt of such
certificate, the applicable Borrower shall pay directly to such Lender such amount as will
compensate such Lender for such loss, cost or expense as provided herein, unless such Lender has
failed to timely give notice to the Company of such claim for compensation as provided herein, in
which event no Borrower shall have any obligation to pay such claim.

          Section 2.12. Letters of Credit.

          (a) Letters of Credit. Subject to the terms and conditions hereof, each Issuing Bank
agrees to issue, from time to time prior to the Commitment Termination Date, at the request of the
Company and on behalf of the Lenders and in reliance on their obligations under this Section 2.12,
one or more letters of credit (each a “Letter of Credit”) for the Company’s or any of its
Subsidiaries’ account in a face amount in each case of at least $500,000 or, if denominated in a
currency other than U.S. Dollars, the Dollar Equivalent of $500,000, and in an aggregate undrawn
face amount for all Letters of Credit at any time outstanding not to exceed the Revolving Credit
Commitment Amount; provided, that an Issuing Bank shall not issue or amend a Letter of Credit
pursuant to this Section 2.12 if, after the issuance thereof, (i) the sum of the Swingline Exposure
plus the Dollar Equivalent of the outstanding Revolving Loans and L/C Obligations would thereby
exceed the Revolving Credit Commitment Amount (determined in accordance with Section 10.19) then in
effect, (ii) the Dollar Equivalent of the aggregate undrawn face amount of all Letters of Credit
then outstanding would at any time thereafter (giving effect to the respective scheduled expiration
dates thereof and any automatic extensions provided therein) exceed the Revolving Credit Commitment
Amount scheduled to be in effect at any such time thereafter (giving effect to any reductions
resulting from the scheduled expiration of the Commitments of Declining Lenders not offset by new
or increased Commitments of Replacement Lenders or Extending Lenders pursuant to Section 2.16),
(iii) the issuance of such Letter of Credit would violate any legal or regulatory restriction then
applicable to such Issuing Bank or any Lender as notified by such Issuing Bank or such Lender to
the Administrative Agent before the date of issuance of such Letter of Credit, (iv) the Dollar
Equivalent of the L/C Obligations would exceed $150,000,000 (the “Letter of Credit Sublimit”), or
(v) the Dollar Equivalent of the L/C Obligations with respect to Letters of Credit issued by such
Issuing Bank would exceed $50,000,000, unless otherwise agreed to by such Issuing Bank in its sole
discretion; and provided, further that, if there exists a Defaulting Lender, no Issuing Bank shall
be required to issue a Letter of Credit unless the Company shall have complied with Section 2.12(g)
with respect to the actual or potential Fronting Exposure in respect of issued Letters of Credit
and such proposed Letter of Credit. Letters of Credit and any increases and extensions thereof
hereunder may be issued in face amounts of either Dollars, Euros, Pounds, Australian

[Revolving Credit Agreement]

31

 

Dollars, Canadian Dollars, Singapore Dollars or Kroner; provided further, that the Dollar
Equivalent amount of the principal amount of outstanding Revolving Loans and Letters of Credit in
Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and Kroner determined, with
respect to each such Revolving Loan or Letter of Credit, in accordance with Section 10.19 on the
date such Letter of Credit is issued, increased or extended, as applicable, shall not exceed in the
aggregate the Foreign Currency Sublimit.

          (b) Issuance Procedure. To request that an Issuing Bank issue a Letter of Credit, the
Company shall deliver to such Issuing Bank and the Administrative Agent (with a duplicate copy to
an operations employee of such Issuing Bank as designated by such Issuing Bank from time to time) a
duly executed Issuance Request substantially in the form of Exhibit 2.12 (each an “Issuance
Request”), together with a duly executed application for the relevant Letter of Credit
substantially in such Issuing Bank’s customary form or in such other form as may be approved by the
Company and such Issuing Bank (each an “Application”), or such other computerized issuance or
application procedure, instituted from time to time by such Issuing Bank and the Administrative
Agent and agreed to by the Company, completed to the reasonable satisfaction of such Issuing Bank
and the Administrative Agent, and such other information as such Issuing Bank and the
Administrative Agent may reasonably request. In the event of any irreconcilable difference or
inconsistency between this Agreement and an Application, the provisions of this Agreement shall
govern. Upon receipt by an Issuing Bank and the Administrative Agent of a properly completed and
executed Application and any other reasonably requested information at least three (3) Business
Days prior to any requested issuance date (or such shorter period to which such Issuing Bank may
agree in its sole discretion), such Issuing Bank will process such Application in accordance with
its customary procedures and issue the requested Letter of Credit on the requested issuance date.
The Company may cancel any requested issuance of a Letter of Credit prior to the issuance thereof.
An Issuing Bank that issues a Letter of Credit will notify the Administrative Agent and each Lender
of the amount, currency, and expiration date of such Letter of Credit it issues promptly upon
issuance thereof. Unless cash collateralized or other satisfactory arrangements with respect
thereto have been made as provided below, or unless a later date is otherwise agreed to by the
applicable Issuing Bank, each Letter of Credit shall have an expiration date no later than five (5)
Business Days before the Commitment Termination Date. If an Issuing Bank issues any Letters of
Credit with expiration dates that automatically extend unless such Issuing Bank gives notice that
the expiration date will not so extend, such Issuing Bank will give such notice of non-renewal
before the time necessary to prevent such automatic extension if (and will not give such notice of
non-renewal before such time unless) before such required notice date (i) the expiration date of
such Letter of Credit if so extended would be later than five (5) Business Days before the
Commitment Termination Date, (ii) the Commitment Termination Date shall have occurred, (iii) a
Default or an Event of Default exists and the Required Lenders have given such Issuing Bank
instructions not to so permit the expiration date of such Letter of Credit to be extended, or (iv)
such Issuing Bank is so directed by the Company; provided, however, that any Letter of Credit may
have an expiration date later than five (5) Business Days before the Commitment Termination Date,
if (X) the Borrower requesting such Letter of Credit shall provide, no later than the Commitment
Termination Date, (1) cash collateral to the Administrative Agent in an amount equal to 105% of the
undrawn face amount of such Letter of Credit or (2) a back-to-back letter of credit in an amount
equal to 105% of the undrawn face amount of such Letter of Credit from a bank or financial
institution whose short-term unsecured debt rating is rated A or above

[Revolving Credit Agreement]

32

 

from either S&P or Moody’s (or such other bank or financial institution satisfactory to the
applicable Issuing Bank) and which provides that the Administrative Agent may make a drawing
thereunder in the event that such Issuing Bank pays a drawing under such Letter of Credit or (Y)
other arrangements satisfactory to the applicable Issuing Bank in its sole discretion shall have
been made with respect to such Letter of Credit. Each Issuing Bank that issues a Letter of Credit
agrees to issue amendments to any Letter of Credit increasing its amount, or extending its
expiration date, at the request of the Company, subject to the conditions precedent for all
Borrowings of Section 4.2 and the other terms and conditions of this Section 2.12.

          (c) The Company’s Reimbursement Obligations.

          (i) The Company hereby irrevocably and unconditionally agrees to reimburse each Issuing
Bank for each payment or disbursement made by such Issuing Bank to settle its obligations
under any draft drawn or other payment made under a Letter of Credit (a “Reimbursement
Obligation”) within two (2) Business Days from when such draft is paid or other payment is
made with either funds not borrowed hereunder or with a Borrowing of Revolving Loans subject
to Section 2.3 and the other terms and conditions contained in this Agreement. The
Reimbursement Obligation shall bear interest (which the Company hereby promises to pay) from
and after the date such draft is paid or other payment is made until (but excluding the
date) the Reimbursement Obligation is paid at the lesser of (x) the Highest Lawful Rate, or
(y) the Base Rate (in the case of a Letter of Credit payable in Dollars) or the rate of
interest that would then be applicable hereunder to an Adjusted LIBOR Loan with an Interest
Period of one month (in the case of a Letter of Credit payable in Euros, Pounds, Australian
Dollars, Canadian Dollars, Singapore Dollars or Kroner), in each case so long as the
Reimbursement Obligation shall not be past due, and thereafter at the default rate per annum
as set forth in Section 2.7(c), whether or not the Commitment Termination Date shall have
occurred. If any such payment or disbursement is reimbursed to an Issuing Bank on the date
such payment or disbursement is made by such Issuing Bank, interest shall be paid on the
reimbursable amount for one (1) day. An Issuing Bank that issues a Letter of Credit shall
give the Company notice of any drawing on such Letter of Credit within one (1) Business Day
after such drawing is paid.

          (ii) The Company agrees for the benefit of each Issuing Bank and each Lender that,
notwithstanding any provision of any Application, the obligations of the Company under this
Section 2.12(c) and each applicable Application shall be absolute, unconditional and
irrevocable and shall be performed strictly in accordance with the terms of this Agreement
and each applicable Application under all circumstances whatsoever (other than the defense
of payment in accordance with this Agreement), including, without limitation, the following
circumstances (subject in all cases to the defense of payment in accordance with this
Agreement):

               (1) any lack of validity or enforceability of any of the L/C Documents;

               (2) any amendment or waiver of or any consent to depart from all or any of the
provisions of any of the L/C Documents;

[Revolving Credit Agreement]

33

 

               (3) the existence of any claim, set-off, defense or other right the Company may have at
any time against a beneficiary of a Letter of Credit (or any person for whom a beneficiary
may be acting), an Issuing Bank, any Lender or any other Person, whether in connection with
this Agreement, another L/C Document or any unrelated transaction;

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

               (5) payment by any Issuing Bank under a Letter of Credit against presentation to such
Issuing Bank of a draft or certificate that does not comply with the terms of the Letter of
Credit; or

               (6) any other act or omission to act or delay of any kind by any Issuing Bank, any
Lender or any other Person or any other event or circumstance whatsoever that might, but for
the provisions of this Section 2.12(c), constitute a legal or equitable discharge of the
Company’s obligations hereunder, under an Issuance Request or under an Application;

provided, however, the foregoing shall not be construed to excuse an Issuing Bank from liability to
the Company to the extent of any direct damages (but excluding consequential damages, which are
hereby waived to the extent not prohibited by applicable law) suffered by the Company that are
caused by such Issuing Bank’s gross negligence or willful misconduct.

          (d) The Participating Interests. Each Lender severally and not jointly agrees to purchase
from each Issuing Bank, and such Issuing Bank hereby agrees to sell to each Lender, an undivided
percentage participating interest, to the extent of its Percentage, in each Letter of Credit issued
by, and Reimbursement Obligation owed to, such Issuing Bank in connection with a Letter of Credit.
Upon any failure by the Company to pay any Reimbursement Obligation in connection with a Letter of
Credit issued by an Issuing Bank at the time required in Sections 2.12(c) and 2.3(e), or if such
Issuing Bank is required at any time to return to the Company or to a trustee, receiver,
liquidator, custodian or other Person any portion of any payment by the Company of any
Reimbursement Obligation in connection with a Letter of Credit, such Issuing Bank shall promptly
give notice of same to each Lender, and such Issuing Bank shall have the right to require each
Lender to fund its participation in such Reimbursement Obligation. Each Lender (except the Issuing
Bank that issued such Letter of Credit, if it is also a Lender) shall pay to such Issuing Bank an
amount equal to such Lender’s Percentage of such unpaid or recaptured Reimbursement Obligation not
later than the Business Day it receives notice from such Issuing Bank to such effect, if such
notice is received before 2:00 P.M., or not later than the following Business Day if such notice is
received after such time. If a Lender fails to pay timely such amount to an Issuing Bank, it shall
also pay to such Issuing Bank interest on such amount accrued from the date payment of such amount
was made by such Issuing Bank to the date of such payment by the Lender at a rate per annum equal
to the Base Rate in effect for each such day and only after such payment shall such Lender be
entitled to receive its Percentage of each payment received on the relevant Reimbursement
Obligation and of interest paid thereon. The several obligations of the Lenders to the Issuing
Banks under this Section 2.12(d) shall be

[Revolving Credit Agreement]

34

 

absolute, irrevocable and unconditional under any and all circumstances whatsoever and shall not be
subject to any set-off, counterclaim or defense to payment any Lender may have or have had against
the Company, any Issuing Bank, any other Lender or any other Person whatsoever including, but not
limited to, any defense based on the failure of the demand for payment under the Letter of Credit
to conform to the terms of such Letter of Credit or the legality, validity, regularity or
enforceability of such Letter of Credit and INCLUDING, BUT NOT LIMITED TO, THOSE RESULTING FROM AN
ISSUING BANK’S OWN SIMPLE OR CONTRIBUTORY NEGLIGENCE. Without limiting the generality of the
foregoing, such obligations shall not be affected by any Default or Event of Default or by any
subsequent reduction or termination of any Commitment of a Lender, and each payment by a Lender
under this Section 2.12 shall be made without any offset, abatement, withholding or reduction
whatsoever.

          (e) Letter of Credit Amounts. Unless otherwise specified herein, the amount of a
Letter of Credit at any time shall be deemed to be the Dollar Equivalent of the stated amount of
such Letter of Credit in effect at such time; provided, however, that with respect to any Letter of
Credit that, by its terms or the terms of any Application related thereto, provides for one or more
automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be
deemed to be the Dollar Equivalent of the maximum stated amount of such Letter of Credit after
giving effect to all such increases, whether or not such maximum stated amount is in effect at such
time.

          (f) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of
Credit issued or outstanding hereunder is in support of any obligations of, or is for the account
of, a Subsidiary, the Company shall be obligated to reimburse the applicable Issuing Bank hereunder
for any and all drawings under such Letter of Credit. The Company hereby acknowledges that the
issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of the Company,
and that the Company’s business derives substantial benefits from the businesses of such
Subsidiaries.

          (g) Letter of Credit Fronting Exposure. If, at any time there shall exist any
Fronting Exposure with respect to Letters of Credit, then the Company shall, if the full amount of
such Fronting Exposure has not been reallocated pursuant to Section 2.19(a)(iv), promptly upon the
request of the Administrative Agent or the applicable Issuing Bank, take one or more of the
following actions as the Company may elect: (i) deliver to the Administrative Agent Collateral to
secure such unallocated Fronting Exposure in accordance with Section 7.4(b) and/or (ii) enter into
other arrangements satisfactory to such Issuing Bank (in such Issuing Bank’s sole discretion) with
the Issuing Bank to eliminate such actual or potential Fronting Exposure.

          Section 2.13. Commitment Terminations. The Company shall have the right at any time and from time to
time, upon three (3) Business Days’ prior and irrevocable written notice (provided, such notice may
be conditioned upon the effectiveness of other credit facilities or the closing of one or more
securities offerings, in which case such notice shall be deemed rescinded if such condition shall
fail to be satisfied by the proposed effective date of such commitment termination, provided,
further, that upon any such rescission the Company shall be liable for any breakage fees and
funding losses that are required to be paid pursuant to Section 2.11) to the Administrative Agent,
to terminate or reduce the Commitments or the Swingline Commitment without premium or penalty, in
whole or in part, with any partial reduction (i) to be

[Revolving Credit Agreement]

35

 

in an amount not less than $5,000,000 as determined by the Company and in integral multiples of
$5,000,000 and (ii) as to the Commitments, to be allocated ratably among the Lenders in proportion
to their respective Commitments; provided, that the Revolving Credit Commitment Amount may not be
reduced to an amount less than the sum of the Swingline Exposure plus the Dollar Equivalent of the
aggregate principal amount of outstanding Revolving Loans and L/C Obligations, after converting, if
necessary, any such outstanding Obligations to their Dollar Equivalent amounts in accordance with
Section 10.19 and after giving effect to payments on such proposed termination or reduction date;
provided, however, that for purposes of determining the amount of L/C Obligations in the
immediately preceding proviso, such L/C Obligations may be reduced on a dollar-for-dollar basis by
the amount of (a) cash collateral deposited with the Administrative Agent for the purpose of
securing such L/C Obligations, and (b) the face amount of back-to-back letters of credit issued in
connection with one or more Letters of Credit included in such L/C Obligations by a bank(s) or
financial institution(s) whose short-term unsecured debt rating is rated A or above from either S&P
or Moody’s or such other bank(s) or financial institution(s) satisfactory to the Required Lenders
with an expiration date of at least five (5) days after the expiration date of the applicable
backstopped Letter of Credit and which provides that the Administrative Agent may make a drawing
thereunder in the event that a drawing is made under the applicable backstopped Letter of Credit;
provided further that the Revolving Credit Commitment Amount may not be reduced to an amount less
than the Swingline Commitment, after giving effect to any contemporaneous reduction thereof. If,
after giving effect to any reduction of the Commitments, the Foreign Currency Sublimit, the Letter
of Credit Sublimit, or the Designated Borrower Sublimit exceeds the amount of the Commitments, such
sublimit shall be automatically reduced by the amount of such excess. The Administrative Agent
shall give prompt notice to each Lender of any such termination or reduction of the Commitments or
the Swingline Commitment. Any termination of Commitments or the Swingline Commitment pursuant to
this Section 2.13 is permanent and may not be reinstated.

          Section 2.14. Increase of Commitments; Additional Lenders.

          (a) So long as no Event of Default has occurred and is continuing, from time to time after the
Initial Availability Date, the Company may elect to increase the Revolving Credit Commitment Amount
up to a total amount not to exceed $600,000,000 as of the Syndication Closing Date, and upon at
least 20 days’ written notice to the Administrative Agent (or such shorter period as Administrative
Agent and Company may agree), up to a total amount not to exceed $800,000,000 at any time
thereafter in effect (the amount of any such increase, the “Additional Commitment Amount”).

          (b) The Company may designate one or more banks or other financial institutions (which may be,
but need not be, one or more of the existing Lenders) which at the time agree to, in the case of
any such Person that is an existing Lender, increase its Commitment and in the case of any other
such Person (an “Additional Lender”), become a party to this Agreement; provided, however, that any
bank or financial institution that is not an existing Lender must be acceptable to the
Administrative Agent, the Swingline Lender and the Issuing Banks, which acceptance will not be
unreasonably withheld or delayed. The sum of the increases in the Commitments of the existing
Lenders pursuant to this subsection (b) plus the Commitments of the Additional Lenders shall not in
the aggregate exceed the Additional

[Revolving Credit Agreement]

36

 

Commitment Amount. No Lender shall have any obligation whatsoever to agree to increase its
Commitment.

          (c) An increase in the aggregate amount of the Commitments pursuant to this Section
2.14 shall become effective upon the receipt by the Administrative Agent of a Joinder Agreement
signed by the Company, by each Additional Lender and by each other Lender whose Commitment is to be
increased, together with such evidence of appropriate corporate authorization on the part of the
Company with respect to the increase in the Commitments and such opinions of counsel for the
Company with respect to the increase in the Commitments as the Administrative Agent may reasonably
request and, with respect to such increase as of the Syndication Closing Date, a certificate
substantially in the form described in Section 4.1(a)(vi).

          (d) Upon the acceptance of any such agreement by the Administrative Agent, the Revolving
Credit Commitment Amount shall automatically be increased by the amount of the Commitments added
through such agreement and the Commitment amounts of each Lender set forth on the signature pages
hereto shall automatically be deemed to be updated.

          (e) Upon any increase in the aggregate amount of the Commitments pursuant to this Section
2.14 that is not pro rata among all Lenders, (x) the Borrowers, the Administrative Agent and
the Lenders shall as of the effective date of such increase make adjustments to the outstanding
principal amount of Revolving Loans (but not any interest accrued thereon or any accrued fees prior
to such date), including, subject to the conditions specified in Section 4.2, the borrowing of
additional Revolving Loans hereunder and the repayment of Revolving Loans plus all applicable
accrued interest, fees and expenses as shall be necessary to provide for Revolving Loans by the
Lenders in proportion to their respective Commitments after giving effect to such increase,
together with any breakage fees and funding losses that are required to be paid pursuant to Section
2.11, and each Lender shall be deemed to have made an assignment of its outstanding Revolving Loans
and Commitment, and assumed outstanding Revolving Loans and Commitments of other Lenders as of the
effective date of such increase as may be necessary to effect the foregoing, and (y) effective upon
such increase, the amount of the unfunded participations held by each Lender in each Letter of
Credit then outstanding shall be adjusted such that, after giving effect to such adjustments, the
Lenders shall hold unfunded participations in each such Letter of Credit in the proportion its
respective Commitment bears to the aggregate Commitments after giving effect to such increase.

          Section 2.15. Additional Interest Costs.

          (a) Mandatory Costs Rate. If and so long as any Lender is required to make special
deposits with the Bank of England, to maintain reserve asset ratios or to pay fees, in each case in
respect of such Lender’s Eurocurrency Loans in any currency other than Dollars, such Lender may
require each Borrower to pay, contemporaneously with each payment of interest on each of such
Loans, additional interest on such Loan at a rate per annum equal to the Mandatory Costs Rate
calculated in accordance with the formula and in the manner set forth in Exhibit 2.15
hereto.

          (b) Other Requirements for Additional Interest. If and so long as any Lender is
required to comply with reserve assets, liquidity, cash margin or other requirements of any

[Revolving Credit Agreement]

37

 

monetary or other authority (including any such requirement imposed by the European Central
Bank or the European System of Central Banks, but excluding requirements reflected in the Statutory
Reserve Rate or the Mandatory Costs Rate) in respect of any of such Lender’s Eurocurrency Loans in
any currency other than Dollars, such Lender may require each Borrower to pay, contemporaneously
with each payment of interest on each of such Loans subject to such requirements, additional
interest on such Loan at a rate per annum specified by such Lender to be the cost to such Lender of
complying with such requirements in relation to such Loan.

          (c) Determination of Amounts Due. Any additional interest owed pursuant to paragraph
(a) or (b) above shall be determined by the relevant Lender and notified to the Company (with a
copy to the Administrative Agent) in the form of a certificate setting forth such additional
interest at least five Business Days before each date on which interest is payable for the relevant
Loan, and such additional interest so notified to the Company by such Lender shall be payable to
the Administrative Agent for the account of such Lender on each date on which interest is payable
for such Loan.

          (d) Limitation on Amounts Due. Subject to the provisions of Section 8.3(c), failure
or delay on the part of any Lender on any occasion to demand additional interest pursuant to this
Section shall not constitute a waiver of such Lender’s right to demand such additional interest on
any subsequent occasion.

          Section 2.16. Extensions of Commitment Termination Date. So long as no Event of Default has occurred and
is continuing, no earlier than 60 days and at least 45 days prior to any anniversary of the
Effective Date, the Company may (but in no event on more than two occasions during the term of this
Agreement), by written notice to the Administrative Agent, request that the Commitment Termination
Date then in effect be extended for a 1-year period. On each such occasion, the Administrative
Agent shall promptly notify each Lender of such request. If a Lender agrees, in its individual and
sole discretion, to so extend its Commitment (an “Extending Lender”), it shall deliver to the
Administrative Agent a written notice of its agreement to do so no earlier than 30 days prior to
such anniversary date and the Administrative Agent shall promptly thereafter notify the Company of
such Extending Lender’s agreement to extend its Commitment (and such agreement shall be irrevocable
until such anniversary date). The Commitment of any Lender that fails to accept or respond to the
Company’s request for extension of the Commitment Termination Date (a “Declining Lender”) shall be
terminated on the Commitment Termination Date then in effect for such Lender (without regard to any
extension by other Lenders) and on such Commitment Termination Date the Borrowers shall pay in full
the unpaid principal amount of all Revolving Loans and Reimbursement Obligations owing to such
Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued and
unpaid under this Agreement to the date of such payment of principal and all other amounts due to
such Declining Lender under this Agreement. The Administrative Agent shall promptly notify each
Extending Lender of the aggregate Commitments of the Declining Lenders. Each Extending Lender may
offer to increase its respective Commitment by an aggregate amount up to the aggregate amount of
the Declining Lenders’ Commitments and such Extending Lender shall deliver to the Administrative
Agent a notice of its offer to so increase its Commitment no later than 15 days prior to such
anniversary date (and such offer shall be irrevocable until such anniversary date). To the extent
the aggregate amount of extended Commitments is less than the aggregate amount of Commitments so
requested to be extended

[Revolving Credit Agreement]

38

 

pursuant to the foregoing, the Company shall have the right to require any Declining Lender at any
time thereafter to (and any such Declining Lender shall) assign in full its rights and obligations
under this Agreement to one or more banks or other financial institutions (which may be, but need
not be, one or more of the existing Lenders) which at the time agree to, in the case of any such
Person that is an existing Lender, increase its Commitment and in the case of any other such Person
(a “Replacement Lender”) become a party to this Agreement; provided that (i) such assignment is
otherwise in compliance with Section 10.10(b), and (ii) such Declining Lender receives payment in
full of the unpaid principal amount of all Revolving Loans and Reimbursement Obligations owing to
such Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued
and unpaid under this Agreement to the date of such payment of principal and all other amounts due
to such Declining Lender under this Agreement. If, but only if, Extending Lenders and Replacement
Lenders have agreed to provide Commitments in an aggregate amount greater than 50% of the aggregate
amount of the Commitments outstanding immediately prior to such anniversary date, the Commitment
Termination Date of such Extending Lenders and Replacement Lenders shall be extended by one year
effective as of such anniversary of the Effective Date.

          Section 2.17. Swingline Advances.

          (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make
Swingline Loans in Dollars to the Borrowers from time to time prior to the Commitment Termination
Date, in an aggregate principal amount at any time outstanding that will not result in (i) the
aggregate principal amount of outstanding Swingline Loans exceeding the Swingline Commitment or
(ii) the sum of the aggregate Swingline Exposure plus the Dollar Equivalent of the aggregate
outstanding principal amount of the Revolving Loans plus the L/C Obligations of all Lenders
(determined in accordance with Section 10.19) exceeding the Revolving Credit Commitment Amount then
in effect; provided that the Swingline Lender shall not be required to make a Swingline Loan to
refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and
conditions set forth herein, each Borrower may borrow, repay and reborrow Swingline Loans.

          (b) To request a Swingline Loan, the Company shall deliver, by hand delivery or telecopier, a
duly completed and executed Swingline Loan Request substantially in the form of Exhibit
2.17 (each a “Swingline Request”) to the Administrative Agent and the Swingline Lender, not
later than 2:00 p.m., on the day of a proposed Swingline Loan. Each such Swingline Request shall
be irrevocable and shall specify the requested date (which shall be a Business Day) and the amount
of the requested Swingline Loan and the applicable Borrower. The Swingline Lender shall make each
Swingline Loan available to the applicable Borrower to an account as directed in writing by the
Company in the applicable Swingline Request maintained with the Administrative Agent by 3:00 p.m.
on the requested date of such Swingline Loan. The Company shall not request a Swingline Loan if at
the time of or immediately after giving effect to such Swingline Loan a Default or Event of Default
has occurred and is continuing or would result therefrom. The Swingline Lender shall not make a
Swingline Loan if it has received notice from a Borrower or any Lender that a Default or Event of
Default exists or would result from such Swingline Loan. Swingline Loans shall be made in minimum
amounts of $2,500,000 and integral multiples of $100,000 above such amount.

[Revolving Credit Agreement]

39

 

          (c) Each Borrower shall have the right at any time and from time to time to repay any
Swingline Loan, in whole or in part, upon giving written notice to the Swingline Lender and the
Administrative Agent before 12:00 noon on the proposed date of repayment.

          (d) The Swingline Lender may at any time in its discretion by written notice given to the
Administrative Agent (provided such notice requirement shall not apply if the Swingline Lender and
the Administrative Agent are the same entity) not later than 11:00 a.m. on the next succeeding
Business Day following such notice require the Revolving Lenders to acquire participations on such
Business Day in all or a portion of the Swingline Loans then outstanding. Such notice shall
specify the aggregate amount of Swingline Loans in which Lenders will participate. Promptly upon
receipt of such notice, the Administrative Agent, or if the Swingline Lender and the Administrative
Agent are the same entity, the Swingline Lender, will give notice thereof to each Lender,
specifying in such notice such Lender’s applicable Percentage of such Swingline Loan or Loans.
Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above,
to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s
Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its
obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and
unconditional and shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or Event of Default or reduction or termination of the Revolving
Credit Commitment Amount and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever. Each Lender shall comply with its obligation under this
paragraph by wire transfer of immediately available funds, in the same manner as provided in
Section 2.5(a) with respect to Loans made by such Lender, and the Administrative Agent shall
promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The
Administrative Agent shall notify the Company of any participations in any Swingline Loan acquired
by the Revolving Lenders pursuant to this paragraph, and thereafter payments in respect of such
Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any
amounts received by the Swingline Lender from any Borrower (or other party on behalf of any
Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a
sale of participations therein shall be promptly remitted to the Administrative Agent. Any such
amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent
to the Lenders that shall have made their payments pursuant to this paragraph, as their interests
may appear. The purchase of participations in a Swingline Loan pursuant to this paragraph shall
not relieve the Borrowers of any default in the payment thereof.

          (e) If, at any time there shall exist any Fronting Exposure with respect to the Swingline
Exposure, then the Company shall, if the full amount of such Fronting Exposure has not been
reallocated pursuant to Section 2.19(a)(iv), promptly upon the request of the Administrative Agent
or the Swingline Lender, deliver to the Administrative Agent Collateral, in accordance with Section
7.4(b), to secure such unallocated Fronting Exposure.

          Section 2.18. Designated Borrowers.

          (a) The Company may at any time, upon not less than fifteen (15) Business Days’ notice from
the Company to the Administrative Agent (or such shorter period as may be agreed by the
Administrative Agent in its sole discretion), designate the Designated Borrower to

[Revolving Credit Agreement]

40

 

receive Loans hereunder by delivering to the Administrative Agent (which shall promptly
deliver counterparts thereof to each Lender) a duly executed notice and agreement in substantially
the form of Exhibit 2.18A (a “Designated Borrower Request and Assumption Agreement”). Following
the giving of any notice pursuant to this Section 2.18(a), if the designation of such Designated
Borrower obligates the Administrative Agent or any Lender to comply with “know your customer” or
similar identification procedures in circumstances where the necessary information is not already
available to it, the Company shall, promptly upon the request of the Administrative Agent or any
Lender, supply such documentation and other evidence as is reasonably requested by the
Administrative Agent or any Lender in order for the Administrative Agent or such Lender to carry
out and be satisfied it has complied with the results of all necessary “know your customer” or
other similar checks under all applicable laws and regulations.

          (b) Within five (5) Business Days after receiving notice from the Company or the
Administrative Agent of the Company’s intent to designate a Subsidiary as a Designated Borrower for
a Designated Borrower that is organized under the laws of a jurisdiction other than of the United
States or a political subdivision thereof, any Lender that may not legally lend to, establish
credit for the account of and/or do any business whatsoever with such Designated Borrower directly
or through an Affiliate of such Lender as provided in the immediately preceding paragraph (a
“Protesting Lender”) shall so notify the Company and the Administrative Agent in writing. With
respect to each Protesting Lender, the Company shall, effective on or before the date that such
Designated Borrower shall have the right to borrow hereunder, (A) notify the Administrative Agent
and such Protesting Lender that the Commitments of such Protesting Lender shall be terminated and
either (1) the Borrowers shall pay in full the unpaid principal amount of all Revolving Loans and
Reimbursement Obligations owing to such Protesting Lender, together with all accrued and unpaid
interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment
of principal and all other amounts due to such Protesting Lender under this Agreement, or (2) the
Company shall have the right to require any Protesting Lender at any time thereafter to (and any
such Protesting Lender shall) assign in full its rights and obligations under this Agreement to one
or more banks or other financial institutions (which may be, but need not be, one or more existing
Lenders) which at the time agree to, in the case of any such Person that is an existing Lender,
increase it Commitment and in the case of any other Person become a party to this Agreement;
provided that (x) such assignment is otherwise in compliance with Section 10.10(b), and (y) such
Protesting Lender receives payment in full of the unpaid principal amount of all Revolving Loans
and Reimbursement Obligations owing to such Protesting Lender, together with all accrued and unpaid
interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment
of principal and all other amounts due to such Protesting Lender under this Agreement; or (B)
cancel its request to designate such Subsidiary as a “Designated Borrower” hereunder.

          (c) The parties hereto acknowledge and agree that prior to the Designated Borrower becoming
entitled to utilize the Revolving Credit provided for herein, the Administrative Agent and the
Lenders shall have received the duly executed Company Guaranty, together with such supporting
resolutions, incumbency certificates, opinions of counsel and other documents or information, in
form, content and scope reasonably satisfactory to the Administrative Agent, as may be required by
the Administrative Agent or the Required Lenders, and Notes signed by the Designated Borrower to
the extent any Lenders so require. Promptly

[Revolving Credit Agreement]

41

 

following receipt of the Company Guaranty and all such requested resolutions, incumbency
certificates, opinions of counsel and other documents or information, the Administrative Agent
shall send a notice in substantially the form of Exhibit 2.18B (a “Designated Borrower Notice”) to
the Company and the Lenders specifying the effective date upon which the Designated Borrower shall
constitute a Borrower for purposes hereof, whereupon each of the Lenders agrees to permit such
Designated Borrower to receive Loans hereunder, on the terms and conditions set forth herein, and
each of the parties agrees that such Designated Borrower otherwise shall be a Borrower for all
purposes of this Agreement.

          (d) The Obligations of the Designated Borrower shall be guaranteed by the Company pursuant to
the Company Guaranty.

          (e) The Designated Borrower hereby irrevocably appoints the Company as its agent for all
purposes relevant to this Agreement and each of the other Credit Documents, including (i) the
giving and receipt of notices, (ii) the execution and delivery of all documents, instruments and
certificates contemplated herein and all modifications hereto, and (iii) the receipt of the
proceeds of any Loans made by the Lenders, to any such Designated Borrower hereunder. Any
acknowledgment, consent, direction, certification or other action which might otherwise be valid or
effective only if given or taken by all Borrowers, or by each Borrower acting singly, shall be
valid and effective if given or taken only by the Company, whether or not any such other Borrower
joins therein. Any notice, demand, consent, acknowledgement, direction, certification or other
communication delivered to the Company in accordance with the terms of this Agreement shall be
deemed to have been delivered to each Designated Borrower.

          (f) The Company may from time to time, upon not less than 15 Business Days’ notice from the
Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative
Agent in its sole discretion), terminate a Designated Borrower’s status as such, provided that
there are no outstanding Loans payable by such Designated Borrower, or other amounts payable by
such Designated Borrower on account of any Loans made to it, as of the effective date of such
termination. The Administrative Agent will promptly notify the Lenders of any such termination of a
Designated Borrower’s status.

          Section 2.19. Defaulting Lenders.

          (a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement
or any other Credit Document, if any Lender becomes a Defaulting Lender, then, until such time as
such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

          (i) Waivers and Amendments. Such Defaulting Lender’s right to approve or
disapprove any amendment, waiver or consent with respect to this Agreement or any other
Credit Document shall be restricted as set forth in Section 10.11.

          (ii) Reallocation of Payments. Any payment of principal, interest, fees or
other amounts received by the Administrative Agent for the account of such Defaulting Lender
(whether voluntary or mandatory, at maturity, pursuant to Article 7 or otherwise, and
including any amounts made available to the Administrative Agent by

[Revolving Credit Agreement]

42

 

such Defaulting Lender pursuant to Section 10.6), shall be applied at such time or
times as may be determined by the Administrative Agent as follows: first, to the payment of
any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second,
to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the
Issuing Banks or Swingline Lender hereunder; third, if so determined by the Administrative
Agent or requested by the Issuing Banks or Swingline Lender, to be held as Collateral for
future funding obligations of such Defaulting Lender of any participation in any Swingline
Loan or Letter of Credit; fourth, as the Company may request (so long as no Default or Event
of Default exists), to the funding of any Loan in respect of which such Defaulting Lender
has failed to fund its portion thereof as required by this Agreement, as determined by the
Administrative Agent; fifth, if so determined by the Administrative Agent and the Company,
to be held in a non-interest bearing deposit account and released in order to satisfy
obligations of such Defaulting Lender to fund Loans under this Agreement; sixth, to the
payment of any amounts owing to the Lenders, the Issuing Banks or Swingline Lender as a
result of any judgment of a court of competent jurisdiction obtained by any Lender, the
Issuing Banks or Swingline Lender against such Defaulting Lender as a result of such
Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no
Default or Event of Default exists, to the payment of any amounts owing to a Credit Party as
a result of any judgment of a court of competent jurisdiction obtained by such Credit Party
against such Defaulting Lender as a result of such Defaulting Lender’s breach of its
obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise
directed by a court of competent jurisdiction; provided that if (x) such payment is a
payment of the principal amount of any Loans or Reimbursement Obligations in respect of
which such Defaulting Lender has not fully funded its appropriate share and (y) such Loans
or Reimbursement Obligations were made at a time when the conditions set forth in Section
4.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and
Reimbursement Obligations owed to, all non-Defaulting Lenders on a pro rata basis prior to
being applied to the payment of any Loans of, or Reimbursement Obligations owed to, such
Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a
Defaulting Lender that are applied (or held to be applied) pursuant to this Section
2.19(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and such
Defaulting Lender shall have no recourse to any Credit Party for the payment of such
amounts, and each Lender irrevocably consents hereto and the application of such payments in
accordance with this Section shall not constitute an Event of Default or a Default, and no
payment of principal of or interest on the Loans of such Defaulting Lender shall be
considered to be overdue for purposes of any Credit Document, if, had such payments been
applied without regard to this Section, no such Event of Default or Default would have
occurred and no such payment of principal of or interest on the Loans of such Defaulting
Lender would have been overdue.

          (iii) Certain Fees. Facility fees under Section 3.1(a) shall cease to accrue
on the Commitment of such Defaulting Lender and such Defaulting Lender shall not be entitled
to receive any letter of credit fees under Section 3.1(c), in each case for any period
during which such Lender is a Defaulting Lender (and the Company shall not be required to
pay any such fees that otherwise would have been required to have been paid to such
Defaulting Lender).

[Revolving Credit Agreement]

43

 

          (iv) Reallocation of Percentages to Reduce Fronting Exposure. During any
period in which there is a Defaulting Lender, for purposes of computing the amount of the
obligation of each non-Defaulting Lender to acquire, refinance or fund participations in
Letters of Credit or Swingline Loans pursuant to Sections 2.12 and 2.17, the “Percentage” of
each non-Defaulting Lender shall be computed without giving effect to the Commitment of such
Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only if,
at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of
Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire,
refinance or fund participations in Letters of Credit and Swingline Loans shall not exceed
the positive difference, if any, of (1) the Commitment of such non-Defaulting Lender
minus (2) the Revolving Credit Exposure of such non-Defaulting Lender.

          (b) Defaulting Lender Cure. If the Company, the Administrative Agent, the Swingline
Lender and the Issuing Banks agree in writing in their sole discretion that a Defaulting Lender
should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the
parties hereto, whereupon as of the effective date specified in such notice and subject to any
conditions set forth therein (which may include arrangements with respect to any Collateral), that
Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other
Lenders or take such other actions as the Administrative Agent may determine to be necessary to
cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to
be held on a pro rata basis by the Lenders in accordance with their Percentages (without giving
effect to Section 2.19(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender;
provided that no adjustments will be made retroactively with respect to fees accrued or payments
made by or on behalf of any Credit Party while such Lender was a Defaulting Lender; and provided,
further, that except to the extent otherwise expressly agreed by the affected parties, no change
hereunder in any Lender’s status from Defaulting Lender to non-Defaulting Lender will constitute a
waiver or release of any claim of any party hereunder arising from that Lender’s having been a
Defaulting Lender.

          (c) No Waiver. The rights and remedies against, and with respect to, a Defaulting
Lender under this Section 2.19 are in addition to, and cumulative and not in limitation of, all
other rights and remedies that the Administrative Agent and each Lender, Issuing Bank, Swingline
Lender, the Company or any other Credit Party may at any time have against, or with respect to,
such Defaulting Lender.

FEES AND PAYMENTS

          Section 3.1. Fees.

          (a) Facility Fees. The Company agrees to pay to the Administrative Agent for the
account of each Lender a facility fee, which shall accrue at the Applicable Facility Fee Rate on
the daily amount of the Commitment of such Lender (whether used or unused) during the period from
and including the Initial Availability Date to but excluding the date on which such Commitment
terminates; provided that, if such Lender continues to have any Revolving Credit

[Revolving Credit Agreement]

44

 

Exposure or Swingline Exposure after its Commitment terminates, then such facility fee shall
continue to accrue on the daily amount of the sum of such Lender’s Revolving Credit Exposure plus
such Lender’s Swingline Exposure from and including the date on which its Commitment terminates to
but excluding the date on which such Lender ceases to have any Revolving Credit Exposure and
Swingline Exposure. Accrued facility fees shall be payable in arrears on the last day of March,
June, September and December of each year, commencing on March 31, 2011, on the date(s) on which
the Commitments shall have terminated and the Lenders shall have no further Revolving Credit
Exposures, and on the Commitment Termination Date. All facility fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).

          (b) Reserved.

          (c) Letter of Credit Fees. Commencing March 31, 2011, and thereafter on the last day
of each March, June, September and December, the Company shall pay to the Administrative Agent
quarterly in arrears, for the period until the next Letter of Credit fee payment date, for the
ratable account of the Lenders, a non-refundable fee payable in Dollars equal to the Applicable
Margin multiplied by the outstanding face amount or increase of such Letter of Credit during such
period calculated on the basis of a 360 day year and actual days elapsed and based on the then
scheduled expiration date of the Letter of Credit; provided, if any Lender shall become a
Defaulting Lender, then without prejudicing any right or remedy that the Company may have with
respect to, on account of, arising from or relating to any event pursuant to which such Lender
shall be a Defaulting Lender, no such letter of credit fee shall accrue for the account of such
Lender from and after the date upon which such Lender shall have become a Defaulting Lender until
such time as such Lender is no longer a Defaulting Lender. For any Letter of Credit issued with a
face amount in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner,
the fees shall be converted into Dollars using the applicable Exchange Rate in effect five (5)
Business Days before any fee with respect thereto shall be due and payable hereunder. In addition,
the Company shall pay to each Issuing Bank solely for such Issuing Bank’s account, in connection
with each Letter of Credit issued by such Issuing Bank, customary issuance and administrative fees,
fronting fees and expenses for such Letter of Credit as agreed from time to time between such
Issuing Bank and the Company.

          (d) Administrative Agent and Arrangement Fees. The Company shall pay to the
Administrative Agent the fees from time to time agreed to by the Company and the Administrative
Agent and the arrangement fees previously agreed to by the Company and the Co-Arrangers.

          (e) Payment of Fees. All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent for distribution, in the case of facility
fees and Letter of Credit fees (other than issuance and administrative fees payable to the Issuing
Banks), to the Lenders.

          Section 3.2. Place and Application of Payments.

          (a) All payments of principal of and interest on the Loans, Reimbursement Obligations and all
fees and other amounts payable by any Credit Party under the Credit

[Revolving Credit Agreement]

45

 

Documents shall be made free and clear of any set-off, counterclaim or defense by such Credit
Party to the Administrative Agent (or, in the case of Swingline Loans, to the Swingline Lender,
except as provided in Section 2.17), for the benefit of the Lenders and the Issuing Banks entitled
to such payments, in immediately available funds on the due date thereof (i) in the case of
payments in U.S. Dollars, no later than 2:00 P.M. in the applicable Administrative Agent’s Account
or such other location as the Administrative Agent may designate in writing to the Company, and
(ii) in the case of payments in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore
Dollars, or Kroner, no later than 11:00 A.M. (at the office of the applicable Administrative
Agent’s Account for payments in such currency) in the applicable Administrative Agent’s Account.
Any payments received by the Administrative Agent from any Credit Party after the time specified in
the preceding sentence shall be deemed to have been received on the next Business Day. If the
applicable Borrower does not, or is unable for any reason to, effect payment of a Loan or
Reimbursement Obligation to the Lenders in the applicable currency or if the applicable Borrower
shall default in the payment when due of any payment in such currency, the Lenders may, at their
option, require such payment to be made to the Lenders in the Dollar Equivalent of such currency
determined in accordance with Section 10.19. With respect to any amount due and payable in Euros,
Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner, each Borrower agrees to
hold the Lenders harmless from any losses, if any, that are incurred by the Lenders arising from
any change in the value of Dollars in relation to such currency between the date such payment
became due and the date of payment thereof (other than losses incurred by any Lender due to the
gross negligence or willful misconduct of such Lender). The Administrative Agent will, on the same
day each payment is received or deemed to have been received in accordance with this Section 3.2,
cause to be distributed like funds in like currency to each Lender owed an Obligation for which
such payment was received, pro rata based on the respective amounts of such type of Obligation then
owing to each Lender.

          (b) If any payment received by the Administrative Agent under any Credit Document is
insufficient to pay in full all amounts then due and payable to the Administrative Agent and the
Lenders under the Credit Documents, such payment shall be distributed by the Administrative Agent
and applied by the Administrative Agent and the Lenders in the order set forth in Section 7.7. In
calculating the amount of Obligations owing each Lender other than for principal and interest on
Loans and Reimbursement Obligations and fees under Section 3.1, the Administrative Agent shall only
be required to include such other Obligations that Lenders have certified to the Administrative
Agent in writing are due to such Lenders.

          Section 3.3. Withholding Taxes.

          (a) Payments Free of Withholding. Except as otherwise required by law and subject to
Section 3.3(b), each payment by the Borrowers to any Lender, any Issuing Bank, the Swingline Lender
or the Administrative Agent under this Agreement or any other Credit Document shall be made without
withholding for or on account of any present or future taxes. If any such withholding is so
required, the applicable Borrower shall make the withholding and pay the amount withheld to the
appropriate governmental authority before penalties attach thereto or interest accrues thereon.
Moreover, in the case of any such present or future taxes imposed by or within the jurisdiction in
which the applicable Borrower is incorporated, any jurisdiction from which the applicable Borrower
makes any payment under this Agreement or any other Credit Document, or (in each case) any
political subdivision or taxing authority thereof or therein,

[Revolving Credit Agreement]

46

 

excluding, in the case of each Lender, each Issuing Bank, the Swingline Lender and the
Administrative Agent, the following taxes:

          (i) taxes imposed on, based upon, or measured by such Lender’s, such Issuing Bank’s,
the Swingline Lender’s or the Administrative Agent’s net income, profits, gains, overall
revenues or receipts, and branch profits, franchise and similar taxes imposed on it;

          (ii) taxes imposed on such Lender, such Issuing Bank, the Swingline Lender or the
Administrative Agent as a result of a present or former connection between the taxing
jurisdiction and such Lender, such Issuing Bank, the Swingline Lender or Administrative
Agent, or any owner or affiliate thereof, as the case may be, other than a connection
resulting solely from the transactions contemplated by this Agreement;

          (iii) taxes imposed as a result of the transfer by such Lender, such Issuing Bank, the
Swingline Lender or Administrative Agent of its interest in this Agreement or any other
Credit Document or a designation by such Lender, such Issuing Bank, the Swingline Lender or
the Administrative Agent (other than pursuant to Section 8.3(c)) of a new Lending Office
(other than taxes imposed as a result of any change in treaty, law or regulation after such
transfer of such Lender’s, such Issuing Bank’s, the Swingline Lender’s or the
Administrative Agent’s interest in this Agreement or any other Credit Document or
designation of a new Lending Office);

          (iv) taxes imposed by the United States of America (or any political subdivision
thereof or tax authority therein) upon a Lender, Issuing Bank, Swingline Lender or
Administrative Agent organized under the laws of a jurisdiction outside of the United
States, except to the extent that such tax is imposed as a result of any change in
applicable law, regulation or treaty (other than any addition of or change in any
“anti-treaty shopping,” “limitation of benefits,” or similar provision applicable to a
treaty) after the date hereof, in the case of each Lender, Issuing Bank, Swingline Lender or
Administrative Agent originally a party hereto or, in the case of any Purchasing Lender (as
defined in Section 10.10(b)) or other Issuing Bank or Administrative Agent, after the date
on which it becomes a Lender, Issuing Bank, or Administrative Agent, as the case may be; or

          (v) taxes which would not have been imposed but for (a) the failure of such Lender,
such Issuing Bank, the Swingline Lender or the Administrative Agent, as the case may be, to
provide on a timely basis (I) the applicable forms prescribed by the Internal Revenue
Service, as required pursuant to Section 3.3(b) (unless excused pursuant to Section 3.3(c)),
or (II) any other form, certification, documentation or proof which is reasonably requested
by the Company, or (b) a determination by a taxing authority or a court of competent
jurisdiction that a form, certification, documentation or other proof provided by such
Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent to establish an
exemption from such tax, assessment or other governmental charge is false or not properly
completed;

[Revolving Credit Agreement]

47

 

(all such present or future taxes, excluding only the taxes described in the preceding
clauses (i) through (v), being hereinafter referred to as “Indemnified Taxes”), the applicable
Borrower shall forthwith pay such additional amount as may be necessary to ensure that the net
amount actually received by each Lender, each Issuing Bank, the Swingline Lender and the
Administrative Agent is free and clear of such Indemnified Taxes (including Indemnified Taxes on
such additional amount) and is equal to the amount that such Lender, such Issuing Bank, the
Swingline Lender or the Administrative Agent (as the case may be) would have received had
withholding of any Indemnified Taxes not been made. If any Borrower pays any Indemnified Taxes, or
any penalties or interest in connection therewith, it shall deliver official tax receipts
evidencing the payment or certified copies thereof, or other evidence of payment if such tax
receipts have not yet been received by such Borrower (with such tax receipts to be delivered within
fifteen (15) days after being actually received), to the Lender, the Swingline Lender, Issuing Bank
or the Administrative Agent on whose account such withholding was made (with a copy to the
Administrative Agent if not the recipient of the original) within fifteen (15) days of such
payment. If the Administrative Agent, any Issuing Bank, the Swingline Lender or any Lender pays
any Indemnified Taxes which any Borrower has failed to withhold or pay to the appropriate
governmental authority, or any penalties or interest in connection therewith, such Borrower shall
reimburse the Administrative Agent, that Issuing Bank, the Swingline Lender or that Lender for the
payment in the currency in which such payment was made within thirty (30) days after the receipt of
written demand therefor. Such Lender, such Issuing Bank, the Swingline Lender or the
Administrative Agent shall make written demand on the Company for reimbursement hereunder no later
than ninety (90) days after the earlier of (i) the date on which such Lender, such Issuing Bank,
the Swingline Lender or the Administrative Agent makes payment of the Indemnified Taxes, penalties
and interest, and (ii) the date on which the relevant taxing authority or other governmental
authority makes written demand upon such Lender, such Issuing Bank, the Swingline Lender or the
Administrative Agent for payment of the Indemnified Taxes, penalties and interest. Any such demand
shall describe in reasonable detail such Indemnified Taxes, penalties or interest, including the
amount thereof if then known to such Lender, such Issuing Bank, the Swingline Lender or the
Administrative Agent, as the case may be. In the event that such Lender, the Swingline Lender,
Issuing Bank or the Administrative Agent fails to give the Company timely notice as provided
herein, no Borrower shall have any obligation to pay such claim for reimbursement. In the event
that any taxing authority notifies a Borrower that it has improperly failed to withhold any taxes
(other than Indemnified Taxes) from a payment to any Lender, any Issuing Bank, the Swingline Lender
or the Administrative Agent under this Agreement or any other Credit Document, such Borrower shall
timely and fully pay such taxes to such taxing authority and such Lender, Issuing Bank, Swingline
Lender or Administrative Agent, as the case may be, shall pay the amount of such taxes to such
Borrower within thirty (30) days after the receipt of written demand therefor. If a Borrower is or
will be required to pay an additional amount to a Lender, an Issuing Bank, the Swingline Lender or
the Administrative Agent pursuant to this Section 3.3(a), then such payee shall use reasonable
efforts to take requested measures (including, without limitation, changing the jurisdiction of its
Lending Office) so as to reduce or eliminate any such amounts which may thereafter accrue, if such
change would
 not otherwise be materially disadvantageous to such payee.

          (b) U.S. Withholding Tax Exemptions. Upon the written request of the Company or the
Administrative Agent, each Lender, the Swingline Lender or Issuing Bank that is not a United States
person (as such term is defined in Section 7701(a)(30) of the Code) shall

[Revolving Credit Agreement]

48

 

submit to the Company and the Administrative Agent, promptly after such request, two duly
completed and signed copies of either Form W-8BEN or any successor form (entitling such Lender, the
Swingline Lender or Issuing Bank to a complete exemption from withholding under the Code on all
amounts to be received by such Lender, the Swingline Lender or Issuing Bank, including fees,
pursuant to the Credit Documents) or Form W-8ECI or any successor form (relating to all amounts to
be received by such Lender, the Swingline Lender or Issuing Bank, including fees, pursuant to the
Credit Documents) of the United States Internal Revenue Service, and any other form of the United
States Internal Revenue Service reasonably necessary to accomplish exemption from withholding
obligations or to facilitate the Administrative Agent’s performance under this Agreement.
Thereafter and from time to time, each such Lender, the Swingline Lender or Issuing Bank shall
submit to the Company and the Administrative Agent such additional duly completed and signed copies
of such forms (or such successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may be required under then-current United States law or regulations
to avoid United States withholding taxes on payments in respect of all amounts to be received by
such Lender, the Swingline Lender or Issuing Bank, including fees, pursuant to the Credit
Documents. Upon the request of the Company, each Lender, the Swingline Lender or Issuing Bank that
is a United States person shall submit to the Company a certificate to the effect that it is such a
United States person and is exempt from information reporting under Section 6049 of the Code and
backup withholding under Section 3406 of the Code.

          (c) Inability of Lender to Submit Forms. If any Lender, the Swingline Lender or
Issuing Bank determines in good faith, as a result of any change in applicable law, regulation or
treaty, or in any official application or interpretation thereof, that (i) it is unable to submit
to the Company or Administrative Agent any form or certificate that such Lender, the Swingline
Lender or Issuing Bank is obligated to submit pursuant to subsection (b) of this Section 3.3, (ii)
it is required to withdraw or cancel any such form or certificate previously submitted, or (iii)
any such form or certificate otherwise becomes ineffective or inaccurate, such Lender, the
Swingline Lender or Issuing Bank shall promptly notify the Company and Administrative Agent of such
fact, and such Lender, the Swingline Lender or Issuing Bank shall to that extent not be obligated
to provide any such form or certificate and will be entitled to withdraw or cancel any affected
form or certificate, as applicable.

          (d) Refund of Taxes. If any Lender, Issuing Bank, Swingline Lender or the
Administrative Agent receives a refund or credit of any Indemnified Tax or any tax referred to in
Section 10.3 with respect to which any Borrower has paid any amount pursuant to this Section 3.3 or
Section 10.3, such Lender, such Issuing Bank, the Swingline Lender or the Administrative Agent
shall pay the amount of such refund or credit (including any interest received with respect
thereto) to such Borrower within fifteen (15) days after receipt thereof. A Lender, Issuing Bank,
the Swingline Lender or the Administrative Agent shall provide, at the sole cost and expense of the
Company, such assistance as the Company may reasonably request in order to obtain such a refund or
credit; provided, however, that none of the Administrative Agent, any Lender, any Issuing Bank or
Swingline Lender shall in any event be required to disclose any information to the Company with
respect to the overall tax position (or any other information relating to taxes that such Person
reasonably determines to be confidential) of the Administrative Agent, Issuing Bank, the Swingline
Lender or such Lender.

organized and existing in good standing under the laws of the jurisdiction of its organization;
(ii) has all necessary organizational power and authority to own the property and assets it uses in
its business and otherwise to carry on its present business; and (iii) is duly licensed or

by it or the nature of the property owned or leased by it makes such licensing or qualification
necessary, except where the failure to be so licensed or qualified or to be in good standing, as
the case may be, would not have a Material Adverse Effect.

[Revolving Credit Agreement]

52

 

          Section 5.2. Power and Authority; Validity. Each of the Credit Parties has the organizational power and
authority to execute, deliver and carry out the terms and provisions of the Credit Documents to
which it is a party and has taken all necessary company action to authorize the execution, delivery
and performance of such Credit Documents. Each of the Credit Parties has duly executed and
delivered each Credit Document to which it is a party and each such Credit Document constitutes the
legal, valid and binding obligation of such Credit Party which is a party thereto enforceable
against it in accordance with its terms, subject as to enforcement only to bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights
generally and equitable principles.

          Section 5.3. No Violation. Neither the execution, delivery or performance by any Credit Party of the
Credit Documents to which it is a party nor compliance by it with the terms and provisions thereof,
nor the consummation by it of the transactions contemplated herein or therein, will (i) contravene
in any material respect any applicable provision of any law, statute, rule or regulation, or any
applicable order, writ, injunction or decree of any court or governmental instrumentality, (ii)
conflict with or result in any breach of any term, covenant, condition or other provision of, or
constitute a default under, or result in the creation or imposition of (or the obligation to create
or impose) any Lien other than any Permitted Lien upon any of the property or assets of such Credit
Party or any of its Subsidiaries under, the terms of any material contractual obligation to which
such Credit Party or any of its Subsidiaries is a party or by which they or any of their properties
or assets are bound or to which they may be subject, or (iii) violate or conflict with any
provision of the memorandum of association and articles of association, charter, articles or
certificate of incorporation, partnership or limited liability company agreement, by-laws, or other
applicable governance documents of such Credit Party or any of its Subsidiaries.

          Section 5.4. Litigation. As of the Effective Date and as of the Syndication Closing Date, there are no
actions, suits, proceedings or counterclaims (including, without limitation, derivative or
injunctive actions) pending or, to the knowledge of the Company, threatened against the Company or
any of its Subsidiaries that are reasonably likely to have a Material Adverse Effect.

          Section 5.5. Use of Proceeds; Margin Regulations.

          (a) Use of Proceeds. The proceeds of the Loans shall only be used for capital
expenditures, working capital and other general corporate purposes of the Company and its
Subsidiaries, including for investments and acquisitions and to provide support for any commercial
paper programs of the Company. Letters of Credit will be issued only to support the general
corporate purposes of the Company and its Subsidiaries.

          (b) Margin Stock. Neither the Company nor any of its Subsidiaries is engaged in the
business of extending credit for the purpose of purchasing or carrying margin stock. No proceeds
of the Loans or the Letters of Credit will be used for a purpose which violates Regulations T, U or
X of the Board of Governors of the Federal Reserve System. After application of the proceeds of
the Loans, the issuance of the Letters of Credit, and any acquisitions permitted hereunder, less
than 25% of the assets of each of the Company and its

[Revolving Credit Agreement]

53

Company Act of 1940, as amended.

          Section 5.8. True and Complete Disclosure. All factual information (taken as a whole) furnished by the
Company or any of its Subsidiaries in writing to the Administrative Agent or any Lender in
connection with any Credit Document or any transaction contemplated therein did not, as of the date
such information was furnished (or, if such information expressly related to a specific date, as of
such specific date), contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements therein (taken as a whole), in light of the circumstances
under which such information was furnished, not misleading, except for such statements, if any, as
have been updated, corrected, supplemented, superseded or modified pursuant to a written correction
or supplement furnished to the Lenders prior to the date of this Agreement; provided, that with
respect to projected financial information, each Borrower represents only that such information was
prepared in good faith based upon assumptions believed by it to be reasonable at the time. To the
extent commercially reasonable, the Company has provided such information and has taken such
action, in each case, as has been reasonably requested in writing by the Administrative Agent or
any Lender in order to assist the Administrative Agent or such Lender in maintaining compliance
with the Patriot Act.

          Section 5.9. Financial Statements. The financial statements heretofore delivered to the Lenders for the
Company’s fiscal year ending December 31, 2009 have been prepared in accordance with GAAP applied

for the previous fiscal year. Such annual and quarterly financial statements fairly present in all
material respects on a consolidated basis the financial position of the Company as of the dates
thereof, and the results of operations for the periods indicated, subject in the case of interim
financial statements, to normal year-end audit adjustments and omission of certain footnotes (as
permitted by the SEC). As of the Effective Date, the Company and its Subsidiaries, considered as a
whole, had no material contingent liabilities or material Indebtedness required under GAAP to be
disclosed in a consolidated balance sheet of the Company that were not included in the financial

Material Adverse Effect.

properties (other than any such assessments, fees, charges or levies that are not more than ninety
(90) days past due, or which can thereafter be paid without penalty, or which are being contested
in good faith by appropriate proceedings and for which reserves have been provided in conformity
with GAAP, or which the failure to pay or delay in filing could not reasonably be expected to have
a Material Adverse Effect).

          Section 5.12. Consents. As of the Initial Availability Date, all consents and approvals of, and filings
and registrations with, and all other actions of, all governmental agencies, authorities or
instrumentalities required to have been obtained or made by the Credit Parties in order to execute,

order to obtain the Loans and Letters of Credit hereunder, have been or will have been obtained or
made and are or will be in full force and effect. As of the date of the Designated Borrower

          Section 5.13. Insurance. The Company and its Significant Subsidiaries currently maintain in effect, with
responsible insurance companies, insurance against any loss or damage to all insurable property and
assets owned by it, which insurance is of a character and in or in excess of such amounts as are
customarily maintained by companies similarly situated and operating like property or assets
(subject to self-insured retentions and deductibles), and insurance with respect to employers’ and
public and product liability risks (subject to self-insured retentions and deductibles); provided
that the Company or any Significant Subsidiary may self-insure to the extent and in the manner
normal for companies of like size, type and financial condition.

          Section 5.14. Intellectual Property. The Company and its Subsidiaries own or hold valid licenses to use
all the patents, trademarks, permits, service marks, and trade names that are necessary to the
operation of the business of the Company and its Subsidiaries as presently conducted, except where
the failure to own, or hold valid licenses to use, such patents, trademarks, permits, service
marks, and trade names could not reasonably be expected to have a Material Adverse Effect.

          Section 5.15. Ownership of Property. The Company and its Subsidiaries have good title to or a valid
leasehold interest in all of their real property and good title to, or a valid leasehold interest
in, all of their other property, subject to no Liens except Permitted Liens, except where the
failure to have such title or leasehold interest in such property could not reasonably be expected
to have a Material Adverse Effect.

more (other than the Obligations hereunder and Indebtedness permitted by Section 6.11), in each
case showing the aggregate principal amount thereof, the name of the respective borrower and any

of such Indebtedness.

outstanding as of the Effective Date, with respect to the Company and its Subsidiaries where the
Indebtedness or other obligations secured by such Lien is in a principal amount of $20,000,000 (or,

assets are subject to such Lien, the aggregate principal amount of the Indebtedness secured
thereby, and a description of the Agreements or other instruments creating, granting, or otherwise
giving rise to such Lien.

and keep its properties and equipment necessary to the proper conduct of its business in reasonably
good repair, working order and condition (normal wear and tear excepted) and will from time to time
make all reasonably necessary repairs, renewals, replacements, additions and betterments thereto so
that at all times such properties and equipment are reasonably preserved and maintained, in each
case with such exceptions as could not, individually or in the aggregate, be reasonably expected to
have a Material Adverse Effect; provided, however, that nothing in this Section 6.2 shall prevent
the Company or any Significant Subsidiary from discontinuing the operation or maintenance of any
such properties or equipment if such discontinuance is, in the judgment of the Company or any
Significant Subsidiary, as applicable, desirable in the conduct of its business.

and to the extent that (i) the same is being contested in good faith and by appropriate proceedings

Administrative Agent upon an officer of the Company becoming aware thereof, of (i) the occurrence
of any reportable event (as defined in ERISA) relating to a Plan (other than a multi-employer plan,

by regulation; (ii) receipt of any notice from the PBGC of its intention to seek termination of any
Plan or appointment of a trustee therefor; (iii) the Company’s or any of its Subsidiaries’

of notice of the occurrence of any event that could reasonably be expected to result in the

the Administrative Agent may make a drawing thereunder in the event that an Issuing Bank pays a
drawing under such Letter of Credit. In addition, if the aggregate amount on deposit with the
Collateral Agent exceeds the Collateralized Obligations then existing, then the Administrative
Agent shall release and deliver such excess amount upon the written request of the Company.

          Section 7.5. Notice of Default. The Administrative Agent shall give notice to the Company under Section

(if Section 7.4(a) has not been complied with) the undrawn face amounts of all outstanding Letters
of Credit. In the event that any such Letters of Credit, or any portions thereof, expire without
being drawn, any cash collateral therefor shall be distributed by the Administrative Agent until

CHANGE IN CIRCUMSTANCES

          Section 8.1. Change of Law.

          (a) Notwithstanding any other provisions of this Agreement or any Note, if at any time any
change, after the date hereof (or, if later, after the date the Administrative Agent or any Issuing
Bank or Lender becomes the Administrative Agent or an Issuing Bank or Lender), in applicable law or
regulation or in the interpretation thereof makes it unlawful for any Lender to make or maintain
Eurocurrency Loans or to fund any Loans in Euros, Pounds, Australian Dollars, Canadian Dollars,
Singapore Dollars, or Kroner, or any Issuing Bank to issue any Letter of Credit or to provide
payment thereunder in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or
Kroner, such Lender or Issuing Bank, as the case may be, shall promptly give written notice thereof
and of the basis therefor in reasonable detail to the Company, and such Lender’s or Issuing Bank’s
obligations to fund affected Eurocurrency Loans or make, continue or convert such Loans under this
Agreement, or to issue any such Letters of Credit, as the case may be, shall thereupon be suspended
until it is no longer unlawful for such Lender to make or maintain such Loans or such Issuing Bank
to issue such Letters of Credit.

          (b) Upon the giving of the notice to the Company referred to in subsection (a) above in
respect of any such Loan, and provided the applicable Borrower shall not have prepaid such Loan
pursuant to Section 2.9, (i) any such outstanding Loan of such Lender shall be automatically
converted to a Base Rate Loan in Dollars on the last day of the Interest Period then applicable
thereto or on such earlier date as required by law, and (ii) such Lender shall make or continue its
portion of any requested Borrowing of such Loan as a Base Rate Loan in U.S. Dollars, which Base
Rate Loan shall, for all other purposes, be considered part of such Borrowing.

          (c) Any Lender or Issuing Bank that has given any notice pursuant to Section 8.1(a) shall,
upon determining that it would no longer be unlawful for it to make such Loans or issue such
Letters of Credit, give prompt written notice thereof to the Company and the

Administrative Agent, and upon giving such notice, its obligation to make, allow conversions
into and maintain such Loans or issue such Letters of Credit shall be reinstated.

day of any Interest Period for any Borrowing of Eurocurrency Loans the Administrative Agent
determines in good faith (after consultation with the other Lenders) that, due to changes in
circumstances since the date hereof, adequate and fair means do not exist for determining the LIBOR
Rate (including without limitation, the unavailability of matching deposits in the applicable
currency) or such rate will not accurately reflect the cost to the Required Lenders of funding
Eurocurrency Loans in the applicable currency for such Interest Period, the Administrative Agent
shall give written notice (in reasonable detail) of such determination and of the basis therefor to
the Company and the Lenders, whereupon until the Administrative Agent notifies the Company and
Lenders that the circumstances giving rise to such suspension no longer exist (which the
Administrative Agent shall do promptly after they do not exist), (i) the obligations of the Lenders
to fund Loans in Euro, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars, or Kroner,
or make, continue or convert Loans as or into such Eurocurrency Loans, or to convert Base Rate
Loans into such Eurocurrency Loans, shall be suspended and (ii) each Eurocurrency Loan will
automatically on the last day of the then existing Interest Period therefor, convert into a Base
Rate Loan in U.S. Dollars.

or regulation, or any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Lender or Issuing Bank (or its applicable Lending Office), with any
request or directive (whether or not having the force of law) of any such authority, central bank
or comparable agency exercising control over banks or financial institutions generally issued after
the date hereof (or, if later, after the date the Administrative Agent, Issuing Bank, or Lender
becomes the Administrative Agent, Issuing Bank, or Lender):

          (i) subjects any Lender or Issuing Bank (or its applicable Lending Office) to any tax,
duty or other charge related to any Eurocurrency Loan, Reimbursement Obligation, or its
obligation to advance or maintain Eurocurrency Loans or issue any Letter of Credit, or shall
change the basis of taxation of payments to any Lender or Issuing Bank (or its applicable
Lending Office) of the principal of or interest on its Eurocurrency Loans, Letters of Credit
or Reimbursement Obligation or any participations in any thereof, or any other amounts due
under this Agreement related to its Eurocurrency Loans, Letters of Credit, Reimbursement
Obligations or participations therein, or its obligation to make Eurocurrency Loans, issue
Letters of Credit, or acquire participations therein (except for changes with respect to
taxes that are not Indemnified Taxes pursuant to Section 3.3); or

          (ii) imposes, modifies or deems applicable any reserve, special deposit or similar
requirement (including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System, but excluding for any Eurocurrency Loan any such
requirement included in an applicable Statutory Reserve

[Revolving Credit Agreement]

72

 

Rate) against assets of, deposits with or for the account of, or credit extended by,
any Lender or Issuing Bank (or its applicable Lending Office) or imposes on any Lender or
Issuing Bank (or its Lending Office) or on the interbank market any other condition
affecting its Eurocurrency Loans, Letters of Credit, any Reimbursement Obligations owed to
it, or its participation in any thereof, or its obligation to advance or maintain
Eurocurrency Loans, issue Letters of Credit or participate in any thereof;

and the result of any of the foregoing is to increase the cost to such Lender or Issuing Bank (or
its applicable Lending Office) of advancing or maintaining any Eurocurrency Loan, issuing or
maintaining a Letter of Credit or participating therein, or to reduce the amount of any sum
received or receivable by such Lender or Issuing Bank (or its applicable Lending Office) in
connection therewith under this Agreement or its Note, by an amount deemed by such Lender or
Issuing Bank to be material, then, subject to Section 8.3(c), from time to time, within thirty (30)
days after receipt of a certificate from such Lender or Issuing Bank (with a copy to the
Administrative Agent) pursuant to subsection (c) below setting forth in reasonable detail such
determination and the basis thereof, the Company shall be obligated to pay (or cause the applicable
Designated Borrower to pay) to such Lender or Issuing Bank such additional amount or amounts as
will compensate such Lender or Issuing Bank for such increased cost or reduction.

          (b) If, after the date hereof, the Administrative Agent, any Lender, the Swingline Lender or
Issuing Bank shall have reasonably determined that the adoption after the date hereof of any
applicable law, rule or regulation regarding capital adequacy, or any change therein (including,
without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of
Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A)
or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other
applicable capital adequacy rules heretofore adopted and issued by any governmental authority), or
any change after the date hereof in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Administrative Agent, any Lender, the Swingline Lender
or Issuing Bank (or its applicable Lending Office) with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on such Lender’s, Issuing
Bank’s or Swingline Lender’s capital, or on the capital of any corporation controlling such Lender,
Issuing Bank or Swingline Lender, as a consequence of its obligations hereunder to a level below
that which such Lender, Issuing Bank or Swingline Lender could have achieved but for such adoption,
change or compliance (taking into consideration such Lender’s, Issuing Bank’s, Swingline Lender’s
or its controlling corporation’s policies with respect to capital adequacy in effect immediately
before such adoption, change or compliance) by an amount reasonably deemed by such Lender, Issuing
Bank or Swingline Lender to be material, then, subject to Section 8.3(c), from time to time, within
thirty (30) days after its receipt of a certificate from such Lender, Issuing Bank or Swingline
Lender (with a copy to the Administrative Agent) pursuant to subsection (c) below setting forth in
reasonable detail such determination and the basis thereof, the Company shall pay (or cause the
applicable Designated Borrower to pay) to such Lender, Issuing Bank or Swingline Lender such
additional amount or amounts as will compensate such Lender, Issuing Bank or Swingline Lender for
such reduction or the applicable Borrower may prepay all Eurocurrency Loans of such Lender or
obtain the cancellation of all such Letters of Credit.

[Revolving Credit Agreement]

          (c) Each of the Administrative Agent, the Lenders, the Swingline Lender and the Issuing
Banks that determines to seek compensation or additional interest under this Section 8.3 or Section
2.15 shall give written notice to the Company and, in the case of a Lender, the Swingline Lender or
a Issuing Bank other than the Administrative Agent, the Administrative Agent of the circumstances
that entitle the Administrative Agent, such Lender, the Swingline Lender or such Issuing Bank to
such compensation no later than ninety (90) days after the Administrative Agent, such Lender, the
Swingline Lender or such Issuing Bank receives actual notice or obtains actual knowledge of the
law, rule, order or interpretation or occurrence of another event giving rise to a claim hereunder.
In any event no Borrower shall have any obligation to pay any amount with respect to claims
accruing prior to the ninetieth day preceding such written demand. Each of the Administrative
Agent, the Lenders, the Swingline Lender and the Issuing Banks shall use reasonable efforts to
avoid the need for, or reduce the amount of, such compensation, additional interest, and any
payment under Section 3.3, including, without limitation, the designation of a different Lending
Office, if such action or designation will not, in the sole judgment of the Administrative Agent,
such Lender, the Swingline Lender or such Issuing Bank made in good faith, be otherwise
disadvantageous to it; provided that the foregoing shall not in any way affect the rights of any
Lender, the Swingline Lender or any Issuing Bank or the obligations of the Borrowers under this
Section 8.3 or Section 2.15. A certificate of the Administrative Agent, any Lender, the Swingline
Lender or any Issuing Bank, as applicable, claiming compensation or additional interest under this
Section 8.3 or Section 2.15, and setting forth the additional amount or amounts to be paid to it
hereunder and accompanied by a statement prepared by the Administrative Agent, such Lender,
Swingline Lender or such Issuing Bank, as applicable, describing in reasonable detail the
calculations thereof shall be prima facie evidence of the correctness thereof. In determining such
amount, such Lender, the Swingline Lender or such Issuing Bank may use any reasonable averaging and
attribution methods.

          Section 8.4. Lending Offices. The Administrative Agent, the Swingline Lender, each Lender and each
Issuing Bank may, at its option, elect to make or maintain its Loans and issue its Letters of
Credit hereunder at the Lending Office for each Type and/or currency of Loan or Letter of Credit
available hereunder or at such other of its branches, offices or Affiliates as it may from time to
time elect and designate in a written notice to the Company and the Administrative Agent, provided
that, except in the case of any such transfer to another of its branches, offices or Affiliates
made at the request of the Company, no Borrower shall be responsible for the costs arising under
Section 3.3 or 8.3 resulting from any such transfer to the extent not otherwise applicable to such
Lender, the Swingline Lender or such Issuing Bank prior to such transfer.

          Section 8.5. Discretion of Lender as to Manner of Funding. Subject to the other provisions of this
Agreement, each Lender, the Swingline Lender and each Issuing Bank shall be entitled to fund and
maintain its funding of all or any part of its Loans and Letters of Credit in any manner it sees
fit.

          Section 8.6. Substitution of Lender or Issuing Bank. If (a) any Lender or Issuing Bank has demanded
compensation or additional interest or given notice of its intention to demand compensation or
additional interest under Section 8.3 or Section 2.15, (b) a Borrower is required to pay any
additional amount to any Lender or Issuing Bank under Section 2.11, (c) any Lender or Issuing Bank
is unable to submit any form or certificate required under Section 3.3(b)

[Revolving Credit Agreement]

74

 

or withdraws or cancels any previously submitted form with no substitution therefor, (d) any Lender
or Issuing Bank gives notice of any change in law or regulations, or in the interpretation thereof,
pursuant to Section 8.1, (e) any Lender or Issuing Bank is a Defaulting Lender or has otherwise
been declared insolvent or a receiver or conservator has been appointed for a material portion of
its assets, business or properties, (f) any Lender or Issuing Bank shall seek to avoid its
obligation to make or maintain Loans or issue Letters of Credit hereunder for any reason,
including, without limitation, reliance upon 12 U.S.C. § 1821(e) or (n) (1) (B), (g) any taxes
referred to in Section 3.3 have been levied or imposed (or the Company determines in good faith
that there is a substantial likelihood that such taxes will be levied or imposed) so as to require
withholding or deductions by a Borrower or payment by a Borrower of additional amounts to any
Lender or Issuing Bank, or other reimbursement or indemnification of any Lender or Issuing Bank, as
a result thereof, (h) any Lender shall decline to consent to a modification or waiver of the terms
of this Agreement or any other Credit Documents requested by the Company, or shall fail to give its
consent to a Redomestication under the laws of a jurisdiction that requires Required Lender consent
pursuant to the definition of “Redomestication”, or (i) an Issuing Bank gives notice pursuant to
Section 2.12(a)(iii) that the issuance of the Letter of Credit would violate any legal or
regulatory restriction then applicable to such Issuing Bank, then and in such event, upon request
from the Company delivered to such Lender or Issuing Bank, and the Administrative Agent, such
Lender shall assign, in accordance with the provisions of Section 10.10 and an appropriately
completed Assignment Agreement, all of its rights and obligations under the Credit Documents to
another Lender or a commercial banking institution selected by the Company and (in the case of a
commercial banking institution) reasonably satisfactory to the Administrative Agent, in
consideration for the payments set forth in such Assignment Agreement and payment by the Company
(or the Company shall cause the applicable Designated Borrower to pay) to such Lender of all other
amounts which such Lender may be owed pursuant to this Agreement, including, without limitation,
Sections 2.11, 2.15, 3.3, 8.3 and 10.13.

ARTICLE 9

THE AGENTS AND ISSUING BANKS

          Section 9.1. Appointment and Authorization of Administrative Agent. Each of the Lenders and the
Swingline Lender hereby appoints Wells Fargo Bank, National Association as the Administrative
Agent, and hereby authorizes the Administrative Agent to take such action on each of its behalf and
to exercise such powers under the Credit Documents as are delegated to the Administrative Agent by
the terms thereof, together with such powers as are reasonably incidental thereto.

          Section 9.2. Rights and Powers. The Administrative Agent and the Other Agents, to the extent each such
Person is also a Lender, shall have the same rights and powers under the Credit Documents as any
other Lender and may exercise or refrain from exercising such rights and power as though it were
not an Administrative Agent, or an Other Agent, and the Administrative Agent and the Other Agents
and their respective Controlling Affiliates may accept deposits from, lend money to, and generally
engage in any kind of business with the Company or any of its Subsidiaries or Controlling
Affiliates as if it were not an Administrative Agent or an Other Agent under the Credit Documents.
The term Lender as used in all Credit Documents, unless the context otherwise clearly requires,
includes, to the extent such Person is

[Revolving Credit Agreement]

75

 

also a Lender hereunder, the Administrative Agent and the Other Agents in their respective
individual capacities as a Lender. In the event that Wells Fargo Bank, National Association or any
of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as
amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by any Credit
Party, the parties hereto acknowledge and agree that any payment or property received in
satisfaction of or in respect of any Obligation of such Credit Party hereunder or under any other
Credit Document by or on behalf of Wells Fargo Bank, National Association in its capacity as the
Administrative Agent or the Collateral Agent for the benefit of any Lender, the Swingline Lender or
any Issuing Bank under any Credit Document (other than Wells Fargo Bank, National Association or an
Affiliate of Wells Fargo Bank, National Association) and which is applied in accordance with the
Credit Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust
Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

          Section 9.3. Action by Administrative Agent and the Other Agents. The obligations of the Administrative
Agent and the Other Agents under the Credit Documents are only those expressly set forth therein.
Without limiting the generality of the foregoing, the Administrative Agent shall not be required to
take any action concerning any Default or Event of Default, except as expressly provided in
Sections 7.2 and 7.4. Unless and until the Required Lenders (or, if required by Section 10.11, all
of the Lenders) give such direction (including, without limitation, the giving of a notice of
default as described in Section 7.1(c)), the Administrative Agent may, except as otherwise
expressly provided herein or therein, take or refrain from taking such actions as it deems
appropriate and in the best interest of all the Lenders and the Swingline Lender. In no event,
however, shall the Administrative Agent or the Other Agents be required to take any action in
violation of applicable law or of any provision of any Credit Document, and each of the
Administrative Agent and the Other Agents shall in all cases be fully justified in failing or
refusing to act hereunder or under any other Credit Document unless it first receives any further
assurances of its indemnification from the Lenders that it may require, including prepayment of any
related expenses and any other protection it requires against any and all costs, expenses, and
liabilities it may incur in taking or continuing to take any such action. The Administrative Agent
shall be entitled to assume that no Default or Event of Default, other than non-payment of any
scheduled principal or interest payment due hereunder, exists unless notified in writing to the
contrary by a Lender or the Company. In all cases in which the Credit Documents do not require the
Administrative Agent or the Other Agents to take specific action, the Administrative Agent and each
of the Other Agents shall be fully justified in using its discretion in failing to take or in
taking any action thereunder. Any instructions of the Required Lenders, or of any other group of
Lenders called for under specific provisions of the Credit Documents, shall be binding on all the
Lenders and holders of Revolving Notes.

          Section 9.4. Consultation with Experts. Each of the Administrative Agent and the Other Agents may
consult with legal counsel, independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken by it in good faith in accordance
with the advice of such counsel, accountants or experts.

          Section 9.5. Indemnification Provisions; Credit Decision. Neither the Administrative Agent, the Other
Agents nor any of their directors, officers, agents, or employees shall be liable to any Lender for
any action taken or not taken by them in connection with the

[Revolving Credit Agreement]

76

 

Credit Documents (i) with the consent or at the request of the Required Lenders (or, if required by
Section 10.11, all of the Lenders), or (ii) in the absence of their own gross negligence or willful
misconduct. Neither the Administrative Agent, the Other Agents nor any of their directors,
officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with this Agreement, any
other Credit Document or any Borrowing; (ii) the performance or observance of any of the covenants
or agreements of the Company or any Subsidiary contained herein or in any other Credit Document;
(iii) the satisfaction of any condition specified in Article 4, except receipt of items required to
be delivered to the Administrative Agent; or (iv) the validity, effectiveness, genuineness,
enforceability, value, worth or collectability hereof or of any other Credit Document or of any
other documents or writings furnished in connection with any Credit Document; and the
Administrative Agent and the Other Agents make no representation of any kind or character with
respect to any such matters mentioned in this sentence. The Administrative Agent and the Other
Agents may execute any of their duties under any of the Credit Documents by or through employees,
agents, and attorneys-in-fact and shall not be answerable to the Lenders or any other Person for
the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care.
The Administrative Agent and the Other Agents shall not incur any liability by acting in reliance
upon any notice, consent, certificate, other document or statement (whether written or oral)
believed by it to be genuine or to be sent by the proper party or parties. In particular and
without limiting any of the foregoing, the Administrative Agent and the Other Agents shall have no
responsibility for confirming the accuracy of any Compliance Certificate or other document or
instrument received by any of them under the Credit Documents. The Administrative Agent and the
Other Agents may treat the payee of any Note as the holder thereof until written notice of transfer
shall have been filed with such Administrative Agent signed by such owner in form satisfactory to
such Administrative Agent. Each of the Lenders and the Swingline Lender acknowledges that it has
independently, and without reliance on the Administrative Agent, the Other Agents, the Swingline
Lender or any other Lender, obtained such information and made such investigations and inquiries
regarding the Company and its Subsidiaries as it deems appropriate, and based upon such
information, investigations and inquiries, made its own credit analysis and decision to extend
credit to the Borrowers in the manner set forth in the Credit Documents. It shall be the
responsibility of each Lender and the Swingline Lender to keep itself informed about the
creditworthiness and business, properties, assets, liabilities, condition (financial or otherwise)
and prospects of the Company and its Subsidiaries, and the Administrative Agent and the Other
Agents shall have no liability whatsoever to any Lender or the Swingline Lender for such matters.
The Administrative Agent and the Other Agents shall have no duty to disclose to the Lenders or the
Swingline Lender information that is not required by any Credit Document to be furnished by the
Company or any Subsidiaries to such Agent at such time, but is voluntarily furnished to such Agent
(either in their respective capacity as Administrative Agent or the Other Agents or in their
individual capacity).

          Section 9.6. Indemnity. The Lenders shall ratably, in accordance with their Percentages, indemnify and
hold the Administrative Agent, the Other Agents, and their directors, officers, employees, agents
and representatives harmless from and against any liabilities, losses, costs or expenses suffered
or incurred by it under any Credit Document or in connection with the transactions contemplated
thereby, regardless of when asserted or arising, except to the extent they are promptly reimbursed
for the same by the Company and except to the extent that any

[Revolving Credit Agreement]

77

 

event giving rise to a claim was caused by the gross negligence or willful misconduct of the party
seeking to be indemnified. The obligations of the Lenders under this Section 9.6 shall survive
termination of this Agreement.

          Section 9.7. Resignation.

          (a) Resignation of Agents. The Administrative Agent and the Other Agents may resign
at any time and shall resign upon any removal thereof as a Lender pursuant to the terms of this
Agreement upon at least thirty (30) days’ prior written notice to the Lenders and the Company. Any
resignation of the Administrative Agent shall not be effective until a replacement therefor is
appointed pursuant to the terms hereof. Upon any such resignation of the Administrative Agent or
any Other Agent, the Required Lenders and, so long as no Event of Default shall then exist, with
the consent of the Company (which consent shall not be unreasonably withheld or delayed) shall have
the right to appoint a successor Administrative Agent or Other Agent, as the case may be. If no
successor Administrative Agent or Other Agent, as the case may be, shall have been so appointed by
the Required Lenders and shall have accepted such appointment within thirty (30) days after the
retiring Administrative Agent’s or Other Agent’s giving of notice of resignation, then the retiring
Administrative Agent or Other Agent, as the case may be, may, on behalf of the Lenders and, so long
as no Event of Default shall then exist, with the consent of the Company (which consent shall not
be unreasonably withheld or delayed) appoint a successor Administrative Agent or Other Agent, as
the case may be, which shall be any Lender hereunder or any commercial bank organized under the
laws of the United States of America or of any State thereof and having a combined capital and
surplus of at least $1,000,000,000. Upon the acceptance of its appointment as the Administrative
Agent or the Other Agent hereunder, such successor Administrative Agent or Other Agent, as the case
may be, shall thereupon succeed to and become vested with all the rights and duties of the retiring
Administrative Agent or Other Agent, as the case may be, under the Credit Documents, and the
retiring Administrative Agent or Other Agent shall be discharged from its duties and obligations
thereunder. After any retiring Administrative Agent’s or Other Agent’s resignation hereunder as
Administrative Agent or Other Agent, as the case may be, the provisions of this Article 9 and all
protective provisions of the other Credit Documents shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent or Other Agent, as the case
may be.

          (b) Resignation of Issuing Banks. If at any time an Issuing Bank assigns all of its
Commitment and Loans pursuant to Section 10.10(b), such Issuing Bank may, upon 30 days’ prior
written notice to the Company, the Administrative Agent, and the Lenders, resign as an Issuing
Bank. In such event, the Company may, with the approval of the Administrative Agent and the
acceptance of the duties of an Issuing Bank by the Lender so requested, request that another Lender
serve as Issuing Bank under this Agreement; provided, however, that the absence of any successor
Issuing Bank shall not affect the resignation of the resigning Issuing Bank. Any resigning Issuing
Bank shall retain all the rights, powers, privileges and duties of an Issuing Bank under this
Agreement with respect to all Letters of Credit outstanding as of the effective date of its
resignation and all Reimbursement Obligations with respect thereto (including the right to require
the Lenders to make Loans or fund risk participations in Reimbursement Obligations pursuant to
Section 2.12). Upon the appointment of any successor Issuing Bank (i) such successor Issuing Bank
shall succeed to and become vested with all of the

[Revolving Credit Agreement]

78

 

rights, powers, privileges and duties of an Issuing Bank under this Agreement, and (ii) such
successor Issuing Bank shall issue Letters of Credit in substitution for the Letters of Credit, if
any, previously issued by the resigning Issuing Bank that are outstanding at the time of such
succession or make other arrangements satisfactory to the resigning Issuing Bank to effectively
assume the obligations of the resigning Issuing Bank with respect to such Letters of Credit.

          Section 9.8. Sub-Agent. The Sub-Agent has been designated under this Agreement to carry out certain
duties of the Administrative Agent as described herein. The Sub-Agent shall be subject to each of
the obligations in this Agreement to be performed by the Sub-Agent, and each of the Company and the
Lenders agrees that the Sub-Agent shall be entitled to exercise each of the rights and shall be
entitled to each of the benefits of the Administrative Agent under this Agreement as relate to the
performance of its obligations hereunder.

ARTICLE 10

MISCELLANEOUS

          Section 10.1. No Waiver. No delay or failure on the part of the Administrative Agent, any Lender, the
Swingline Lender or any Issuing Bank, or on the part of the holder or holders of any Notes, in the
exercise of any power, right or remedy under any Credit Document shall operate as a waiver thereof
or as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any
other or further exercise of any other power, right or remedy. To the fullest extent permitted by
applicable law, the powers, rights and remedies under the Credit Documents of the Administrative
Agent, the Lenders, the Issuing Banks and the Swingline Lender and the holder or holders of any
Notes are cumulative to, and not exclusive of, any powers, rights or remedies any of them would
otherwise have.

          Section 10.2. Non-Business Day. Subject to Section 2.4, if any payment of principal or interest on any
portion of any Loan, any Reimbursement Obligation, or any other Obligation shall fall due on a day
which is not a Business Day, interest or fees (as applicable) at the rate, if any, such portion of
any Loan, any Reimbursement Obligation, or other Obligation bears for the period prior to maturity
shall continue to accrue in the manner set forth herein on such Obligation from the stated due date
thereof to the next succeeding Business Day, on which the same shall instead be payable.

          Section 10.3. Documentary Taxes. The Company agrees that it will pay (or cause the applicable Designated
Borrower to pay) any documentary, stamp or similar taxes payable with respect to any Credit
Document, including interest and penalties, in the event any such taxes are assessed irrespective
of when such assessment is made, other than any such taxes imposed as a result of any transfer of
an interest in a Credit Document. Each Lender, each Issuing Bank and the Swingline Lender that
determines to seek compensation under this Section 10.3 shall give written notice to the Company
and, in the case of a Lender, a Issuing Bank or the Swingline Lender other than the Administrative
Agent, the Administrative Agent of the circumstances that entitle such Lender, such Issuing Bank or
the Swingline Lender to such compensation no later than ninety (90) days after such Lender, such
Issuing Bank or the Swingline Lender receives actual notice or obtains actual knowledge of the law,
rule, order or interpretation or occurrence of another event giving rise to a claim hereunder. In
any event, no

[Revolving Credit Agreement]

79

 

Borrower shall have any obligation to pay any amount with respect to claims accruing prior to the
90th day preceding such written demand.

          Section 10.4. Survival of Representations. All representations and warranties made herein or in
certificates given pursuant hereto shall survive the execution and delivery of this Agreement and
the other Credit Documents, and shall continue in full force and effect with respect to the date as
of which they were made as long as any Borrower has any Obligation hereunder or any Commitment
hereunder is in effect.

          Section 10.5. Survival of Indemnities. All indemnities and all provisions relative to reimbursement to
the Lenders, the Swingline Lender and the Issuing Banks of amounts sufficient to protect the yield
of the Lenders, the Swingline Lender and the Issuing Banks with respect to the Loans and the L/C
Obligations, including, but not limited to, Section 2.11, Section 2.15, Section 3.3, Section 7.6,
Section 8.3, Section 10.3, and Section 10.13 hereof, shall, subject to Section 8.3(c), survive the
termination of this Agreement and the other Credit Documents and the payment of the Loans and all
other Obligations and, with respect to any Lender, any Issuing Bank or the Swingline Lender, any
replacement by the Company of such Lender pursuant to the terms hereof, in each case for a period
of one (1) year.

          Section 10.6. Setoff. 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 of, and throughout the continuance of,
any Event of Default, each Lender, each Issuing Bank and the Swingline Lender and each subsequent
holder of any Note is hereby authorized by the Borrowers at any time or from time to time, without
prior notice to the Borrower or any other Person, any such prior notice being hereby expressly
waived, to set off and to appropriate and to apply any and all deposits (general or special,
including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured
or unmatured, but not including trust accounts, and in whatever currency denominated) and any other
Indebtedness at any time owing by that Lender, the Swingline Lender or that Issuing Bank or that
subsequent holder to or for the credit or the account of a Borrower, whether or not matured,
against and on account of the due and unpaid obligations and liabilities of such Borrower to that
Lender, the Swingline Lender or that Issuing Bank or that subsequent holder under the Credit
Documents, irrespective of whether or not that Lender, the Swingline Lender or that Issuing Bank or
that subsequent holder shall have made any demand hereunder. Each Lender, the Swingline Lender or
each Issuing Bank shall promptly give notice to the Company of any action taken by it under this
Section 10.6, provided that any failure of such Lender, the Swingline Lender or such Issuing Bank
to give such notice to the Company shall not affect the validity of such setoff. Each Lender, the
Swingline Lender and each Issuing Bank agrees with each other Lender, the Swingline Lender and each
other Issuing Bank a party hereto that if such Lender, the Swingline Lender or such Issuing Bank
receives and retains any payment, whether by setoff or application of deposit balances or
otherwise, in respect of the Loans or L/C Obligations in excess of its ratable share of payments on
all such Obligations then owed to the Lenders, the Swingline Lender and the Issuing Banks
hereunder, then such Lender, the Swingline Lender or such Issuing Bank shall purchase for cash at
face value, but without recourse, ratably from each of the other Lenders such amount of the Loans
and L/C Obligations and participations therein held by each such other Lender, Swingline Lender or
Issuing Bank as shall be necessary to cause such Lender, Swingline Lender or such Issuing Bank to
share such excess payment ratably with all the other Lenders, the Swingline Lender and the

[Revolving Credit Agreement]

80

 

Issuing Banks; provided, however, that if any such purchase is made by any Lender, Swingline Lender
or any Issuing Bank, and if such excess payment or part thereof is thereafter recovered from such
purchasing Lender, Swingline Lender or Issuing Bank, the related purchases from the other Lenders,
Swingline Lender or the Issuing Banks shall be rescinded ratably and the purchase price restored as
to the portion of such excess payment so recovered, but without interest; provided further, that in
the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so
set off shall be paid over immediately to the Administrative Agent for further application in
accordance with the provisions of Section 2.19 and, pending such payment, shall be segregated by
such Defaulting Lender from its other funds and deemed held in trust for the benefit of the
Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the
Administrative Agent a statement describing in reasonable detail the Obligations owing to such
Defaulting Lender as to which it exercised such right of setoff.

          Section 10.7. Notices.

          (a) Except as otherwise specified herein and except as otherwise provided in Section 10.7(b),
all notices under the Credit Documents shall be in writing (including cable, telecopy or telex) and
shall be given to a party hereunder at its address, telecopier number or telex number set forth
below or such other address, telecopier number or telex number as such party may hereafter specify
by notice to the Administrative Agent and the Company, given by courier, by United States certified
or registered mail, by telegram or by other telecommunication device capable of creating a written
record of such notice and its receipt. Notices under the Credit Documents to the Lenders shall be
addressed to their respective domestic Lending Offices in the United States at the respective
addresses, telecopier or telex number, or telephone numbers set forth on their applicable
Administrative Questionnaire or, in the case of Persons becoming Lenders pursuant to Assignment
Agreements, on their applicable Assignment Agreements, and to the Company, the Administrative

Notwithstanding the foregoing,
materials required to be delivered pursuant to Section 6.6 shall be
delivered to the Administrative Agent as specified in Section 10.7(b) or as otherwise specified to
the Company by the Administrative Agent; provided that any communication that (A) relates to a
request for a new, or a conversion of an existing, Loan or other extension of credit (including any
election of an interest rate or Interest Period relating thereto), (B) relates to the payment of
any principal or other amount due under this Agreement prior to the scheduled date therefor, (C)
provides notice of any Default or Event of Default or (D) is required to be delivered to satisfy
any condition precedent to the effectiveness of any provision of this Agreement and/or any Loan,
Letter of Credit, increase of any Letter of Credit or other extension of credit hereunder, shall be
in writing (including telecopy communication) and mailed, telecopied or delivered pursuant to this
Section 10.7(a).

          (b) The Company will provide to the Administrative Agent all information, documents and other
materials that it is obligated to furnish to the Administrative Agent pursuant to the Credit
Documents, including all notices, requests, financial statements, financial and other reports,
certificates and other information materials, but excluding any such communication that (i) relates
to a request for a new, or a conversion of an existing, Loan, a new Letter of Credit, any increase
of any Letter of Credit, or other extension of credit (including any election of an interest rate
or Interest Period relating thereto), (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 Default
or Event of Default or (iv) is required to be delivered to satisfy any condition precedent to the
effectiveness of any provision of this Agreement and/or any Loan, Letter of Credit, increase of any
Letter of Credit or other extension of credit hereunder (all such non-excluded communications being
referred to herein collectively as “Communications”), by transmitting the Communications in an
electronic/soft medium to Barry.Parks@wellsfargo.com.

The Company further agrees that the Administrative Agent may make the Communications available to
the Swingline Lender, the Lenders and the Issuing Banks by posting the Communications on Intralinks
or a substantially similar electronic transmission system (the “Platform”). The Company
acknowledges that the distribution of material through an electronic medium is not necessarily
secure and that there are confidentiality and other risks associated with such distribution.

THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW) DO
NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND
EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY
KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR
FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE
COMMUNICATIONS OR THE PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS
AFFILIATES OR ANY OF THE RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR
REPRESENTATIVES OF THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES (COLLECTIVELY, “AGENT
PARTIES”) HAVE ANY 

[Revolving Credit Agreement]

83

 

LIABILITY TO THE COMPANY, ANY LENDER, ANY ISSUING BANK OR ANY OTHER PERSON OR ENTITY FOR
DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF
THE TRANSMISSION BY THE COMPANY, ANY OF THE AGENT PARTIES OR ANY OTHER PERSON OF COMMUNICATIONS
THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL
NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH
AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

The Administrative Agent agrees that the receipt of the Communications by the Administrative Agent
at its e-mail address set forth above shall constitute effective delivery of the Communications to
the Administrative Agent for purposes of the Credit Documents. Each of the Lenders, the Swingline
Lender and the Issuing Banks agrees that notice to it (as provided in the next sentence) specifying
that the Communications have been posted to the Platform shall constitute effective delivery of the
Communications to such Lender, Swingline Lender or Issuing Bank, as the case may be, for purposes
of the Credit Documents. Each of the Lenders, the Swingline Lender and the Issuing Banks agrees
(i) to notify the Administrative Agent in writing (including by electronic communication) from time
to time of such Lender’s, Swingline Lender’s or such Issuing Bank’s, as the case may be, e-mail
address to which the foregoing notice may be sent by electronic transmission and (ii) that the
foregoing notice may be sent to such e-mail address.

Nothing herein shall prejudice the right of the Administrative Agent, any Issuing Bank, the
Swingline Lender or any Lender to give any notice or other communication pursuant to any Credit
Document in any other manner specified in such Credit Document.

          Section 10.8. Counterparts. This Agreement may be executed in any number of counterparts, and by the
different parties on different counterpart signature pages, each of which when executed shall be
deemed an original, but all such counterparts taken together shall constitute one and the same
Agreement.

          Section 10.9. Successors and Assigns. This Agreement shall be binding upon the Borrowers, each of the
Lenders, the Issuing Banks, the Swingline Lender, the Administrative Agent, the Other Agents, and
their respective successors and assigns, and shall inure to the benefit of the Borrowers, each of
the Lenders, the Issuing Banks, the Swingline Lender, the Administrative Agent, the Other Agents,
and their respective successors and assigns, including any subsequent holder of any Note; provided,
however, no Borrower may assign any of its rights or obligations under this Agreement or any other
Credit Document without the written consent of all Lenders, the Issuing Banks, the Swingline
Lender, the Administrative Agent and the Other Agents, and the Administrative Agent and the Other
Agents may not assign any of their respective rights or obligations under this Agreement or any
Credit Document except in accordance with Article 9 and no Lender or Issuing Bank may assign any of
its rights or obligations under this Agreement or any other Credit Document except in accordance
with Section 10.10. Any Lender, the Swingline Lender or any Issuing Bank may at any time pledge

[Revolving Credit Agreement]

84

 

or assign all or any portion of its rights under this Agreement and the Notes issued to it (i) to a
Federal Reserve Bank to secure extensions of credit by such Federal Reserve Bank to such Lender,
Swingline Lender or Issuing Bank, or (ii) in the case of any Lender that is a fund comprised in
whole or in part of commercial loans, to a trustee for such fund in support of such Lender’s
obligations to such trustee; provided that no such pledge or assignment shall release a Lender,
Swingline Lender or Issuing Bank from any of its obligations hereunder or substitute any such
Federal Reserve Bank or such trustee for such Lender, Swingline Lender or Issuing Bank as a party
hereto and the Borrowers, the Administrative Agent, the other Lenders, the Swingline Lender and the
Issuing Banks shall continue to deal solely with such Lender, Swingline Lender or Issuing Bank in
connection with the rights and obligations of such Lender, Swingline Lender and Issuing Bank under
this Agreement.

          Section 10.10. Sales and Transfers of Borrowing and Notes; Participations in Borrowings
and Notes.

          (a) Any Lender may, without the consent of, or notice to, the Company and the Administrative
Agent, at any time sell to one or more commercial banking or other financial or lending
institutions, other than Defaulting Lenders (“Participants”) participating interests in any
Commitment of such Lender hereunder, provided that no Lender may sell any participating interests
(other than in the case of Affiliates of such Lender) in any such Commitment hereunder without also
selling to such Participant the appropriate pro rata share of all such Lender’s Commitment, and
provided further that no Lender shall transfer, grant or assign any participation under which the
Participant shall have rights to vote upon or to consent to any matter to be decided by the Lenders
or the Required Lenders hereunder or under any other Credit Document or to approve any amendment to
or waiver of this Agreement or any other Credit Document except to the extent such amendment or
waiver would (i) increase the amount of such Lender’s Commitment and such increase would affect
such Participant, (ii) reduce the principal of, or interest on, any of such Lender’s Borrowings, or
any fees or other amounts payable to such Lender hereunder and such reduction would affect such
Participant, (iii) postpone any date fixed for any scheduled payment of principal of, or interest
on, any of such Lender’s Borrowings, or any fees or other amounts payable to such Lender hereunder
and such postponement would affect such Participant, or (iv) release any collateral security for
any Obligation, except as otherwise specifically provided in any Credit Document. In the event of
any such sale by a Lender of participating interests to a Participant, such Lender’s obligations
under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender
shall remain solely responsible for the performance thereof, such Lender shall remain the holder of
any such Note for all purposes under this Agreement, the Borrowers and the Administrative Agent
shall continue to deal solely and directly with such Lender in connection with such Lender’s rights
and obligations under this Agreement and such Lender shall retain the sole right to enforce the
obligations of the Borrowers under any Credit Document. Each Borrower agrees that if amounts
outstanding under this Agreement and the Notes shall have been declared or shall have become due
and payable in accordance with Section 7.2 or 7.3 upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of setoff in respect of its participating interest in
amounts owing under this Agreement and any Note to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this Agreement or any Note,
provided that such right of setoff shall be subject to the obligation of such Participant to share
with the Lenders, and the Lenders agree to share with such Participant, as provided in

[Revolving Credit Agreement]

85

 

Section 10.6. Each Borrower also agrees that each Participant shall be entitled to the
benefits of and have the obligations under Sections 2.11, 2.15, 3.3 and 8.3 with respect to its
participation in the Commitments and the Borrowings outstanding from time to time, provided that no
Participant shall be entitled to receive any greater amount pursuant to such Sections than the
transferor Lender would have been entitled to receive in respect of the amount of the participation
transferred if no participation had been transferred and provided, further, that Sections 8.3(c)
and 8.6 shall apply to the transferor Lender with respect to any claim by any Participant pursuant
to Section 2.11, 2.15, 3.3 or 8.3 as fully as if such claim was made by such Lender. Anything
herein to the contrary notwithstanding, no Borrower shall at any time be obligated to pay to any
Lender any sum in excess of the sum such Borrower would have been obligated to pay to such Lender
hereunder if such Lender had not sold any participation in its rights and obligations under this
Agreement or any other Credit Document.

          (b) Any Lender may at any time sell to (i) any of such Lender’s Affiliates, to an Approved
Fund or to any other Lender or Affiliate thereof (other than, in each case, a Defaulting Lender, or
an Approved Fund or any Affiliate of such Defaulting Lender), that, in each case, is a commercial
banking or other financial or lending institution not subject to Regulation T of the Board of
Governors of the Federal Reserve System, or (ii) with the prior written consent (which shall not be
unreasonably withheld or delayed) of the Administrative Agent, the Swingline Lender, the Issuing
Banks and if no Event of Default has occurred and is continuing, the Company, to one or more
commercial banking or other financial or lending institutions not described in (i), above that are
not subject to Regulation T of the Board of Governors of the Federal Reserve System (any of (i) or
(ii), a “Purchasing Lender”), all or any part of its rights and obligations under this Agreement
and the other Credit Documents, pursuant to an Assignment Agreement, executed by such Purchasing
Lender and such transferor Lender (and, in the case of a Purchasing Lender described in clause
(ii), above, by the Company, the Administrative Agent and the Issuing Banks) and delivered to the
Administrative Agent; provided that each such sale to a Purchasing Lender (other than an existing
Lender) shall be in the Dollar Equivalent amount of $5,000,000 or more, or if in a lesser amount or
if as a result of such sale the sum of the unfunded Commitment of such Lender plus the aggregate
principal amount of such Lender’s Loans and participations in Letters of Credits would be less than
the Dollar Equivalent amount of $5,000,000 (calculated as hereinafter set forth), such sale shall
be of all of such Lender’s rights and obligations under this Agreement and all of the other Credit
Documents payable to it to one Purchasing Lender. Notwithstanding the requirement of the Company’s
consent set forth above, but subject to all of the other terms and conditions of this Section
10.10(b), any Lender may sell to one or more commercial banking or other financial or lending
institutions not subject to Regulation T of the Board of Governors of the Federal Reserve System,
all or any part of their rights and obligations under this Agreement and the other Credit Documents
with only the consent of the Administrative Agent (which shall not be unreasonably withheld or
delayed) if an Event of Default shall have occurred and be continuing. Upon such execution,
delivery and acceptance, from and after the effective date of the transfer determined pursuant to
such Assignment Agreement, (x) the Purchasing Lender thereunder shall be a party hereto and, to the
extent provided in such Assignment Agreement, have the rights and obligations of a Lender hereunder
with a Commitment as set forth herein and (y) the transferor Lender thereunder shall, to the extent
provided in such Assignment Agreement, be released from its obligations under this Agreement (and,
in the case of an Assignment Agreement covering all or the remaining portion of a transferor
Lender’s rights and obligations under this Agreement,

[Revolving Credit Agreement]

86

 

such transferor Lender shall cease to be a party hereto). Such Assignment Agreement shall be
deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the
addition of such Purchasing Lender and the resulting adjustment of Commitments and Percentages
arising from the purchase by such Purchasing Lender of all or a portion of the rights and
obligations of such transferor Lender under this Agreement, the Notes and the other Credit
Documents. On or prior to the effective date of the transfer determined pursuant to such
Assignment Agreement, the applicable Borrower, at its own expense, shall upon reasonable notice
from the Administrative Agent execute and deliver to the Administrative Agent in exchange for any
surrendered Note, a new Note as appropriate to the order of such Purchasing Lender in an amount
equal to the Commitments assumed by it pursuant to such Assignment Agreement, and, if the
transferor Lender has retained a Commitment or Borrowing hereunder, a new Note to the order of the
transferor Lender in an amount equal to the Commitments or Borrowings retained by it hereunder.
Such new Notes shall be dated the Initial Availability Date and shall otherwise be in the form of
the Notes replaced thereby. The Notes surrendered by the transferor Lender shall be returned by
the Administrative Agent to the Company marked “cancelled.”

          (c) Upon its receipt of an Assignment Agreement executed by a transferor Lender and a
Purchasing Lender (and, in the case of a Purchasing Lender that is not then a Lender or an
Affiliate thereof, by the Administrative Agent and the Issuing Banks and, to the extent required by
Section 10.10(b), by the Company), together with payment by the transferor Lender to the
Administrative Agent hereunder of a registration and processing fee of $3,500 (unless the Company
is replacing such Lender pursuant to the terms hereof, in which event such fee shall be paid by the
Company), the Administrative Agent shall (i) promptly accept such Assignment Agreement, and (ii) on
the effective date of the transfer determined pursuant thereto give notice of such acceptance and
recordation to the Lenders and the Company. The Company shall not be responsible for such
registration and processing fee or any costs or expenses incurred by any Lender, any Purchasing
Lender or the Administrative Agent in connection with such assignment except as provided above.

          (d) If, pursuant to this Section 10.10 any interest in this Agreement or any Loan or Note is
transferred to any transferee which is organized under the laws of any jurisdiction other than the
United States of America or any State thereof, the transferor Lender shall cause such transferee,
concurrently with the effectiveness of such transfer, (i) to represent to the transferor Lender
(for the benefit of the transferor Lender, the Administrative Agent and the Company) that under
applicable law and treaties no taxes will be required to be withheld by the Administrative Agent,
any Borrower or the transferor Lender with respect to any payments to be made to such transferee in
respect of the Loans or the L/C Obligations, (ii) to furnish to the transferor Lender (and, in the
case of any Purchasing Lender, the Administrative Agent and the Company) two duly completed and
signed copies of either U.S. Internal Revenue Service Form W-8BEN or U.S. Internal Revenue Service
Form W-8ECI or such successor forms as shall be adopted from time to time by the relevant United
States taxing authorities (wherein such transferee claims entitlement to complete exemption from
U.S. federal withholding tax on all interest payments hereunder), and (iii) to agree (for the
benefit of the transferor Lender, the Administrative Agent and the Company) to provide the
transferor Lender (and, in the case of any Purchasing Lender, the Administrative Agent and the
Company) new forms as contemplated by Section 3.3(b) upon the expiration or obsolescence of any
previously delivered form and

[Revolving Credit Agreement]

87

 

comparable statements in accordance with applicable U.S. laws and regulations and amendments
duly executed and completed by such transferee, and to comply from time to time with all applicable
U.S. laws and regulations with regard to such withholding tax exemption.

          (e) Notwithstanding any other provisions of this Section 10.10, no transfer or assignment of
the interests of any Lender hereunder or any grant of participations therein shall be permitted if
such transfer, assignment or grant would require any Borrower to file a registration statement with
the SEC or to qualify the Loans, the Notes or any other Obligations under the securities laws of
any jurisdiction.

          (f) In connection with any assignment of rights and obligations of any Defaulting Lender
hereunder, no such assignment shall be effective unless and until, in addition to the other
conditions thereto set forth herein, the parties to the assignment shall make such additional
payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof
as appropriate (which may be outright payment, purchases by the assignee of participations or
subparticipations, or other compensating actions, including funding, with the consent of the
Company and the Administrative Agent, the applicable pro rata share of Loans previously requested
but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor
hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by
such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest accrued
thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and
participations in Letters of Credit and Swingline Loans in accordance with its Percentage.
Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any
Defaulting Lender hereunder shall become effective under applicable law without compliance with the
provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting
Lender for all purposes of this Agreement until such compliance occurs.

          Section 10.11. Amendments, Waivers and Consents. Any provision of the Credit Documents may be amended or
waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Company,
(b) the Required Lenders, and (c) if the rights or duties of the Administrative Agent, the Other
Agents, the Swingline Lender or any Issuing Bank are affected thereby, the Administrative Agent,
the Other Agents, the Swingline Lender or such Issuing Bank, as the case may be, provided that:

          (i) no amendment or waiver shall (A) increase or extend any Commitment of any Lender
without the consent of such Lender, or (B) reduce the amount of or postpone the date for any
scheduled payment of any principal of or interest (including, without limitation, any
reduction in the rate of interest unless such reduction is otherwise provided herein) on any
Loan or Reimbursement Obligation or of any fee payable hereunder, without the consent of
each Lender owed any such Obligation, (C) release any Collateral for any Collateralized
Obligations (other than as provided in accordance with Section 7.4) without the consent of
all Lenders, (D) release the NDC Guaranty (except as expressly provided for therein), during
any period that there is a Designated Borrower, the Company Guaranty (except as expressly
provided for therein), or the provisions of Article 4 hereof without the consent of all
Lenders, (E) change any provision requiring ratable funding or sharing of payments without
the consent of all

[Revolving Credit Agreement]

88

 

Lenders or (F) amend or waive this Section 10.11, the definition herein of “Required
Lenders” or the number of Lenders required to take any action under any other provision of
the Credit Documents without the consent of all Lenders;

          (ii) no amendment or waiver shall, unless signed by each Lender, change the provisions
of this Section 10.11 or the definition of Required Lenders or the number of Lenders
required to take any action under any other provision of the Credit Documents; and

          (iii) notwithstanding anything to the contrary herein, no Defaulting Lender shall have
any right to approve or disapprove any amendment, waiver or consent hereunder (and any
amendment, waiver or consent which by its terms requires the consent of all Lenders or each
affected Lender may be effected with the consent of the applicable Lenders other than
Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be
increased or extended without the consent of such Lender and (y) any waiver, amendment or
modification requiring the consent of all Lenders or each affected Lender that by its terms
affects any Defaulting Lender more adversely than other affected Lenders shall require the
consent of such Defaulting Lender.

          Section 10.12. Headings. Section headings used in this Agreement are for reference only and shall not
affect the construction of this Agreement.

          Section 10.13. Legal Fees, Other Costs and Indemnification. The Company, upon demand by the
Administrative Agent, agrees to pay all reasonable out-of-pocket costs and expenses of the
Administrative Agent (including, without limitation, the reasonable fees and disbursements of legal
counsel to the Administrative Agent) in connection with the preparation and execution of the Credit
Documents (not to exceed such amount previously agreed to by the Administrative Agent), and any
amendment, waiver or consent related thereto, whether or not the transactions contemplated therein
are consummated. The Company further agrees to indemnify and hold harmless each Lender, Issuing
Bank, the Swingline Lender, the Administrative Agent, the Other Agents, and their respective
directors, officers, employees and attorneys (collectively, the “Indemnified Parties”), against all
losses, claims, damages, penalties, judgments, liabilities and expenses (including, without
limitation, all reasonable attorneys’ fees and other reasonable expenses of litigation or
preparation therefor, whether or not such Indemnified Party is a party thereto) which any of them
may pay or incur as a result of (a) any action, suit or proceeding by any third party or
Governmental Authority against such Indemnified Party and relating to any Credit Document, the
Loans, any Letter of Credit, or the application or proposed application by any of a Borrower of the
proceeds of any Loan or use of any Letter of Credit, REGARDLESS OF WHETHER SUCH CLAIMS OR ACTIONS
ARE FOUNDED IN WHOLE OR IN PART UPON THE ALLEGED SIMPLE OR CONTRIBUTORY NEGLIGENCE OF ANY OF THE
INDEMNIFIED PARTIES AND/OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES OR ATTORNEYS, (b)
any investigation of any third party or any Governmental Authority involving any Lender (as a
lender hereunder), any Issuing Bank, the Swingline Lender or the Administrative Agent or the Other
Agents (in such capacity hereunder) and related to any use made or proposed to be made by a
Borrower of the proceeds of any Loan, or use of any Letter of Credit or any transaction financed or
to be financed

[Revolving Credit Agreement]

89

 

in whole or in part, directly or indirectly with the proceeds of any Loan or Letter of Credit, and
(c) any investigation of any third party or any Governmental Authority, litigation or proceeding
involving any Lender (as a lender hereunder), the Swingline Lender (as a swingline lender
hereunder), any Issuing Bank (as an issuer of Letters of Credit hereunder) or the Administrative
Agent or the Other Agents (in such capacity hereunder) and related to any environmental cleanup,
audit, compliance or other matter relating to any Environmental Law or the presence of any
Hazardous Material (including, without limitation, any losses, liabilities, damages, injuries,
costs, expenses or claims asserted or arising under any Environmental Law) with respect to the
Company, regardless of whether caused by, or within the control of, the Company; provided, however,
that the Company shall not be obligated to indemnify any Indemnified Party for any of the foregoing
arising out of such Indemnified Party’s gross negligence, willful misconduct, violation of law or
willful breach of its obligations hereunder, as determined pursuant to a judgment of a court of
competent jurisdiction or as expressly agreed in writing by such Indemnified Party. The Company,
upon demand by the Administrative Agent, the Other Agents, a Lender, the Swingline Lender or a
Issuing Bank at any time, shall reimburse such Agent, Lender, Swingline Lender or Issuing Bank for
any reasonable legal or other expenses incurred in connection with investigating or defending
against any of the foregoing, except if the same is excluded from indemnification pursuant to the
provisions of the preceding sentence. Each Indemnified Party agrees to contest any indemnified
claim if requested by the Company, in a manner reasonably directed by the Company, with counsel
selected by the Indemnified Party and approved by the Company, which approval shall not be
unreasonably withheld or delayed. Any Indemnified Party that proposes or intends to settle or
compromise any such indemnified claim shall give the Company written notice of the terms of such
settlement or compromise reasonably in advance of settling or compromising such claim or proceeding
and shall obtain the Company’s prior written consent thereto, which consent shall not be
unreasonably withheld or delayed; provided that the Indemnified Party shall not be restricted from
settling or compromising any such claim if (i) the Indemnified Party waives its right to indemnity
from the Company in respect of such claim and such settlement or compromise does not materially
increase the Company’s liability pursuant to this Section 10.13 to any related party of such
Indemnified Party, (ii) an Event of Default as described in Section 7.1(a), (b) (as a result of a
default under Section 6.16), (f) or (g) or has occurred and is continuing or (iii) the Indemnified
Party reasonably believes the Company will not be able to satisfy the full amount of such claim and
the Company has failed to provide sufficient collateral to the Indemnified Party to secure the
value of such claim.

          Section 10.14. Governing Law; Submission to Jurisdiction; Waiver of Jury Trial.

     (A) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS, AND THE RIGHTS AND DUTIES OF THE PARTIES
THERETO, SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF

WITH THIS AGREEMENT, AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT
AND NOT BEFORE A JURY.

     (D) EACH PARTY TO THIS AGREEMENT IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER
PROVIDED FOR NOTICES IN SECTION 10.7. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY

[Revolving Credit Agreement]

91

 

PARTY TO THIS AGREEMENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

     (E) EACH OF THE CREDIT PARTIES, THE ADMINISTRATIVE AGENT, THE ISSUING BANKS, THE SWINGLINE
LENDER AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION
REFERRED TO IN THIS SECTION 10.14 OR OTHERWISE RELATING TO THE CREDIT DOCUMENTS ANY PUNITIVE
DAMAGES.

          Section 10.15. Confidentiality. Each of the Agents, the Issuing Banks, the Swingline Lender and Lenders
agree to maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (i) to their respective Affiliates and to prospective Purchasing
Lenders and Participants and their respective directors, officers, employees and agents, including
accountants, legal counsel and other advisors who have reason to use such Information in connection
with the evaluation of the transactions contemplated by this Agreement (subject to similar
confidentiality provisions as provided herein) solely for purposes of evaluating such Information,
(ii) to the extent requested by any regulatory authority, (iii) to the extent required by
applicable law or regulation or by any subpoena or similar legal process, (iv) in connection with
the exercise of any remedies hereunder or any proceedings relating to this Agreement or the other
Credit Documents, (v) with the consent of the Company, or (vi) to the extent such Information (x)
becomes publicly available other than as a result of a breach of this Section 10.15, or (y) becomes
available on a non-confidential basis from a source other than the Company or its Affiliates, or
the Lenders or their respective Affiliates, excluding any Information from such source which, to
the actual knowledge of the Agent, Issuing Bank, the Swingline Lender or Lender receiving such
Information, has been disclosed by such source in violation of a duty of confidentiality to the
Company. For purposes hereof, “Information” means all information received by the Lenders, the
Swingline Lenders or the Issuing Banks from the Company relating to the Company or its business,
other than any such information that is available to the Lenders, the Swingline Lender or the
Issuing Banks on a non-confidential basis prior to disclosure by the Company, excluding any
Information from a source which, to the actual knowledge of the Agent, Issuing Bank, Swingline
Lender or Lender receiving such Information, has been disclosed by such source in violation of a
duty of confidentiality to the Company. The Agents, the Issuing Banks, the Swingline Lender and
the Lenders shall be considered to have complied with their respective obligations if they have
exercised the same degree of care to maintain the confidentiality of such Information as they would
accord their own confidential information.

          Section 10.16. Effectiveness. This Agreement shall become effective on the date (the “Effective Date”) on
which the Company, the Administrative Agent, the Swingline Lender and each Lender have signed and
delivered to the Administrative Agent a counterparty signature page hereto (including by facsimile
or other electronic means) or the Administrative Agent has received a facsimile notice that such a
counterpart has been signed and mailed to the Administrative Agent.

     Section 10.17. Severability. Any provision of this Agreement that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability without invalidating the remaining provisions hereof, and any such prohibition
or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.

     Section 10.18. Currency Conversion. All payments of Obligations under this Agreement, the Notes or any
other Credit Document shall be made in U.S. Dollars, except for Loans funded, or Reimbursement
Obligations with respect to Letters of Credit issued, in Euros, Pounds, Australian Dollars,
Canadian Dollars, Singapore Dollars or Kroner, which shall be repaid, including interest thereon,
in the applicable currency. If any payment of any Obligation, whether through payment by any
Credit Party or the proceeds of any collateral, shall be made in a currency other than the currency
required hereunder, such amount shall be converted into the currency required hereunder at the rate
determined by the Administrative Agent or Issuing Bank, as applicable, as the rate quoted by it in
accordance with methods customarily used by such Person for such or similar purposes as the spot
rate for the purchase by such Person of the required currency with the currency of actual payment
through its principal foreign exchange trading office (including, in the case of the Administrative
Agent, the Sub-Agent) at approximately 11:00 A.M. (local time at such office) two Business Days
prior to the effective date of such conversion, provided that the Administrative Agent or Issuing
Bank, as applicable, may obtain such spot rate from another financial institution actively engaged
in foreign currency exchange if the Administrative Agent or Issuing Bank, as applicable, does not
then have a spot rate for the required currency. The parties hereto hereby agree, to the fullest
extent that they may effectively do so under applicable law, that (i) if for the purposes of
obtaining any judgment or award it becomes necessary to convert from any currency other than the
currency required hereunder into the currency required hereunder any amount in connection with the
Obligations, then the conversion shall be made as provided above on the Business Day before the day
on which the judgment or award is given, (ii) in the event that there is a change in the applicable
conversion rate prevailing between the Business Day before the day on which the judgment or award
is given and the date of payment, the Company will pay (or cause the applicable Designated Borrower
to pay) to the Administrative Agent, for the benefit of the Lenders, such additional amounts (if
any) as may be necessary, and the Administrative Agent, on behalf of the Lenders, will pay to the
applicable Borrower such excess amounts (if any) as result from such change in the rate of
exchange, to assure that the amount paid on such date is the amount in such other currency, which
when converted at the conversion rate described herein on the date of payment, is the amount then
due in the currency required hereunder, and (iii) any amount due from a Borrower under this Section
10.18 shall be due as a separate debt and shall not be affected by judgment or award being obtained
for any other sum due. For the avoidance of doubt, the parties affirm and agree that neither the
fixing of the conversion rate of Pounds or Kroners against the Euro as a single currency, in
accordance with the applicable treaties establishing the European Economic Community and the
European Union, as the case may be, in each case, as amended from time to time, nor the conversion
of the Obligations under this Agreement from Pounds or Kroners into Euros will be a reason for
early termination or revision of this Agreement or prepayment of any amount due under this
Agreement or create any liability of any party towards any other party for any direct or
consequential loss arising from any of these events. As of the date that Pounds or Kroners are no
longer the lawful currency of the United Kingdom or Norway, as the case may be, all funding and
payment Obligations to be

[Revolving Credit Agreement]

93

 

made in such affected currency under this Agreement shall be satisfied in Euros. If, in relation
to the currency of any member state of the European Union that adopts the Euro as its lawful
currency, the basis of accrual of interest expressed in this Agreement in respect of that currency
shall be inconsistent with any convention or practice in the London interbank market for the basis
of accrual of interest in respect of the Euro, such expressed basis shall be replaced by such
convention or practice with effect from the date on which such member state adopts the Euro as its
lawful currency; provided that if any Borrowing in the currency of such member state is outstanding
immediately prior to such date, such replacement shall take effect, with respect to such Borrowing,
at the end of the then current Interest Period.

     Section 10.19. Exchange Rates.

     (a) Determination of Exchange Rates. Not later than 2:00 P.M. (London time) on each
Calculation Date, if any L/C Obligations are outstanding on such date in a currency other than U.S.
Dollars, the applicable Issuing Bank shall determine the Exchange Rate as of such Calculation Date
for all such L/C Obligations outstanding as of such date with respect to all Letters of Credit
issued by such Issuing Bank or its Affiliates (the “Issuing Bank Exchange Rate”) and give prompt
notice thereof to the Administrative Agent. No later than 4:00 P.M. (London time) on each such
Calculation Date, (i) the Administrative Agent shall (i) determine the Exchange Rate (other than
the Issuing Bank Exchange Rate, if applicable) as of such Calculation Date with respect to Euros,
Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and Kroner, and (ii) give notice
thereof, together with notice of the applicable Issuing Bank Exchange Rate, if applicable, to the
Lenders and the Company. The Exchange Rates so determined shall become effective on the first
Business Day immediately following the relevant Calculation Date (a “Reset Date”), shall remain
effective until the next succeeding Reset Date, and shall for all purposes of this Agreement (other
than Section 10.18 or any other provision expressly requiring the use of a current Exchange Rate)
be the Exchange Rates employed in determining the Dollar Equivalent of any amounts of Euros,
Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars or Kroner. Notwithstanding
anything contained herein to the contrary, if any Issuing Bank fails to timely deliver notice of
its Issuing Bank Exchange Rate to the Administrative Agent pursuant to the provisions of this
Section 10.19, the Administrative Agent may determine such rate in accordance with the definition
of Exchange Rate and shall have no liability to such Issuing Bank for such determination.

     (b) Notice of Foreign Currency Loans and Letters of Credit. Not later than 2:00 P.M.
(London time) on each Reset Date and each date on which Loans and/or Letters of Credit denominated
in Euros, Pounds, Australian Dollars, Canadian Dollars, Singapore Dollars and/or Kroner are made or
issued, if any such L/C Obligations are outstanding on such date, the applicable Issuing Bank shall
determine its Issuing Bank Exchange Rate as of such date, if applicable, and give prompt notice
thereof to the Administrative Agent. Not later than 5:00 P.M. (New York time) on each Reset Date
and each date on which Loans and/or Letters of Credit denominated in Euros, Pounds, Australian
Dollars, Canadian Dollars, Singapore Dollars and/or Kroner are made or issued, the Administrative
Agent shall (i) determine the Dollar Equivalent of the aggregate principal amounts of the Loans and
L/C Obligations denominated in such currencies (after giving effect to any Loans and/or Letters of
Credit denominated in such currencies being made, issued, repaid, or cancelled or reduced on such
date), (ii) notify the

[Revolving Credit Agreement]

94

 

Lenders and the Company of the results of such determination and (iii) notify the Issuing
Bank, if applicable, that the conditions to issuance set forth in Section 2.12(a) are satisfied.

     Section 10.20. Change in Accounting Principles, Fiscal Year or Tax Laws. If either the Company or the
Required Lenders notifies the Administrative Agent that (i) any change in accounting principles
from those used in the preparation of the financial statements of the Company referred to in
Section 5.9 is hereafter occasioned by the promulgation of rules, regulations, pronouncements and
opinions by or required by the Financial Accounting Standards Board or the American Institute of
Certified Public Accounts (or successors thereto or agencies with similar functions), and such
change affects the calculation of any component of any financial covenant, standard or term found
in this Agreement, or (ii) there is a change in federal, state or foreign tax laws which affects
the Company’s or any of its Subsidiaries’ ability to comply with the financial covenants, standards
or terms found in this Agreement, then the Company and the Lenders agree to enter into negotiations
in order to amend such provisions (with the agreement of the Required Lenders or, if required by
Section 10.11, all of the Lenders) so as to equitably reflect such changes with the desired result
that the criteria for evaluating any of the Company’s and its Subsidiaries’ financial condition
shall be the same after such changes as if such changes had not been made.

     Section 10.21. Final Agreement. The Credit Documents constitute the entire understanding among the Credit
Parties, the Lenders, the Swingline Lender, the Issuing Banks, and the Administrative Agent and
supersede all earlier or contemporaneous agreements, whether written or oral, concerning the
subject matter of the Credit Documents. THIS WRITTEN AGREEMENT TOGETHER WITH THE OTHER CREDIT
DOCUMENTS REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     Section 10.22. Officer’s Certificates. It is not intended that any certificate of any officer or director
of any Credit Party delivered to the Administrative Agent or any Lender pursuant to this Agreement
shall give rise to any personal liability on the part of such officer or director.

     Section 10.23. Effect of Inclusion of Exceptions. It is not intended that the specification of any
exception to any covenant herein shall imply that the excepted matter would, but for such
exception, be prohibited or required.

     Section 10.24. Margin Stock. Each of the Lenders, the Swingline Lender and Issuing Banks hereby
represents to the other Lenders, Swingline Lender and Issuing Banks that it is not relying on
margin stock as collateral in extending or maintaining any Loan or Letter of Credit.

     Section 10.25. Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf
of any Lender) hereby notifies the Borrowers that pursuant to the requirements of the Patriot Act,
it is required to obtain, verify and record information that identifies each Borrower, which
information includes the name and address of the Borrowers and

[Revolving Credit Agreement]

95

 

other information that will allow such Lender or the Administrative Agent, as applicable, to
identify each Borrower in accordance with the Patriot Act. Each Borrower shall provide, to the
extent commercially reasonable, such information and take such actions as are reasonably requested
by the Administrative Agent or any Lenders in order to assist the Administrative Agent and the
Lenders in maintaining compliance with the Patriot Act.

EXHIBIT 1.1

GUARANTY AGREEMENT

          THIS GUARANTY AGREEMENT (this “Guaranty”), dated as of February 11, 2011 is made by Noble
Drilling Corporation, a Delaware corporation (the “Guarantor”), in favor of (i) the Lenders (as
defined in the Credit Agreement) (as hereinafter defined), (ii) Wells Fargo Bank, National
Association, in its capacity as Administrative Agent (as defined in the Credit Agreement), (iii)
Wells Fargo Bank, National Association, in its capacity as the Swingline Lender (as defined in the
Credit Agreement), (iv) the Other Agents (as defined in the Credit Agreement) and (v) the Issuing
Banks (as defined in the Credit Agreement) (the Lenders, the Administrative Agent, the Other
Agents, the Swingline Lender and the Issuing Banks are each individually referred to herein as a
“Guaranteed Party”, and collectively, as the “Guaranteed Parties”);

WITNESSETH:

          WHEREAS, Noble Corporation, a Cayman Islands exempted company limited by shares (the
“Company”), the Lenders, the Administrative Agent, the Swingline Lender and the Issuing Banks are
parties to a certain Revolving Credit Agreement dated as of February 11, 2011 (as the same may
hereafter be amended, restated, supplemented or otherwise modified from time to time, the “Credit
Agreement”; terms defined therein and not otherwise defined herein being used herein as therein
defined);

          WHEREAS, the Company owns, directly or indirectly, all or a majority of all outstanding
capital stock or other equity interests of the Guarantor;

          WHEREAS, consummation of the transactions pursuant to the Credit Agreement have facilitated
expansion and enhanced the overall financial strength and stability of the Company’s entire
corporate group, including the Guarantor; and

          WHEREAS, it is a requirement under Section 4.1(a) of the Credit Agreement, as a condition to
the making of Loans and the issuance of Letters of Credit, that the Guarantor execute and deliver
this Guaranty, and the Guarantor desires to execute and deliver this Guaranty to satisfy such
requirement;

          NOW, THEREFORE, in consideration of the premises and in order to satisfy the requirements of
the Credit Agreement, and for other good and valuable consideration, the Guarantor hereby agrees as
follows:

          SECTION 1. Guaranty. The Guarantor hereby, irrevocably and unconditionally,
guarantees the punctual payment when due, in lawful money of the United States of America or in
another currency as provided for in Section 3.2(a) of the Credit Agreement (the “Obligation
Currency”), whether at stated maturity, by acceleration or otherwise, of the Loans, L/C
Obligations, and all other Obligations owing by the Company to the Lenders, the Administrative
Agent, the Swingline Lender, the Issuing Banks and Other Agents,

 

or any of them, under the Credit Agreement, the Notes, and the other Credit Documents,
including all renewals, extensions, modifications and refinancings thereof, now or hereafter owing,
whether for principal, interest, fees, expenses, indemnities, reimbursement obligations or
otherwise, and any and all reasonable out-of-pocket expenses (including reasonable attorneys’ fees
and expenses) incurred by the Lenders or the Administrative Agent in enforcing any rights under
this Guaranty (collectively, the “Guaranteed Obligations”), including without limitation, all
interest which, but for the filing of a petition in bankruptcy, would accrue on any principal
portion of the Guaranteed Obligations. Any and all payments by the Guarantor hereunder shall be
made in the Obligation Currency free and clear of and without deduction for any set-off,
counterclaim, or withholding so that, in each case, each Guaranteed Party will receive, after
giving effect to any Indemnified Taxes (as such term is defined in the Credit Agreement), the full
amount, in the Obligation Currency, that it would otherwise be entitled to receive with respect to
the Guaranteed Obligations (but without duplication of amounts for Indemnified Taxes already
included in the Guaranteed Obligations). The Guarantor acknowledges and agrees that this is a
guarantee of payment when due, and not of collection, and that this Guaranty may be enforced up to
the full amount of the Guaranteed Obligations without proceeding against the Company, against any
security for the Guaranteed Obligations, against any other Person or under any other guaranty
covering any portion of the Guaranteed Obligations.

          SECTION 2. Guaranty Absolute. The Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of
such terms or the rights of any Guaranteed Party with respect thereto. The liability of the
Guarantor under this Guaranty shall be absolute and unconditional in accordance with its terms and
shall remain in full force and effect without regard to, and shall not be released, suspended,
discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever,
including, without limitation, the following (whether or not the Guarantor consents thereto or has
notice thereof):

     (a) any change in the time, place or manner of payment of, or in any other term of, all
or any of the Guaranteed Obligations, any waiver, indulgence, renewal, extension, amendment
or modification of or addition, consent or supplement to or deletion from or any other
action or inaction under or in respect of the Credit Agreement or the other Credit
Documents, or any other documents, instruments or agreements relating to the Guaranteed
Obligations or any other instrument or agreement referred to therein or any assignment or
transfer of any thereof;

     (b) any lack of validity or enforceability of the Credit Agreement or the other Credit
Documents, or any other document, instrument or agreement referred to therein or any
assignment or transfer of any thereof;

     (c) any furnishing to the Guaranteed Parties of any additional security or additional
guaranty for the Guaranteed Obligations, or any sale, exchange, release or surrender of, or
realization on, any security or guaranty for the Guaranteed Obligations;

     (d) any settlement or compromise of any of the Guaranteed Obligations, any security
therefor, or any liability of any other party with respect to the Guaranteed

-2-

 

Obligations, or any subordination of the payment of the Guaranteed Obligations to the
payment of any other liability of the Company;

     (e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution,
liquidation or other like proceeding relating to the Guarantor, the Company or any other
Person, or any action taken with respect to this Guaranty by any trustee or receiver, or by
any court, in any such proceeding;

     (f) any nonperfection of any security interest or lien on any collateral, or any
amendment or waiver of or consent to departure from any guaranty or security, for all or any
of the Guaranteed Obligations;

     (g) any application of sums paid by the Company or any other Person with respect to the
liabilities of the Company to the Guaranteed Parties, regardless of what liabilities of the
Company remain unpaid;

     (h) any act or failure to act by any Guaranteed Party which may adversely affect the
Guarantor’s subrogation rights, if any, against the Company to recover payments made under
this Guaranty; and

     (i) any other circumstance which might otherwise constitute a defense available to, or
a discharge of, the Guarantor.

If claim is ever made upon any Guaranteed Party for repayment or recovery of any amount or amounts
received in payment or on account of any of the Guaranteed Obligations, and any Guaranteed Party
repays all or part of said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over the Guaranteed Party or any of its property, or (b)
any settlement or compromise of any such claim effected by the Guaranteed Party with any such
claimant (including, without limitation, the Company or a trustee in bankruptcy for the Company),
then and in such event the Guarantor agrees that any such judgment, decree, order, settlement or
compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the
Credit Agreement, the other Credit Documents, or any other instrument evidencing any liability of
the Company, and the Guarantor shall be and remain liable to the Guaranteed Party for the amounts
so repaid or recovered to the same extent as if such amount had never originally been paid to the
Guaranteed Party.

          SECTION 3. Waiver. The Guarantor hereby waives (a) notice of acceptance of this
Guaranty, (b) notice of the incurrence of any Guaranteed Obligation, (c) notice of acceleration,
(d) notice of intent to accelerate, (e) any requirement that any of the Guaranteed Parties
institute suit, collection proceedings or take any other action to collect any of the Guaranteed
Obligations, (f) diligence and promptness, (g) notice of presentment, demand of payment or protest,
(h) notice of dishonor or nonpayment, (i) notice of suit or taking of other action by the
Guaranteed Parties against the Company and (j) any other notice to the Company or any other party
liable with respect to the Guaranteed Obligations (including, without limitation, any other Person
executing a guaranty of the obligations of the Company).

-3-

 

          SECTION 4. Subrogation. The Guarantor will not exercise any rights against the
Company which it may acquire by way of subrogation or contribution, by any payment made hereunder
or otherwise, until all the Guaranteed Obligations (other than indemnities and other contingent
obligations not then due and payable and as to which no claim has been made as of the time of
determination) shall have been irrevocably paid in full and the Credit Agreement and all Letters of
Credit shall have been irrevocably terminated (unless such Letters of Credit have been cash
collateralized in accordance with the provisions of the Credit Agreement or other arrangements with
respect thereto have been made that are satisfactory to the applicable Issuing Bank). If any
amount shall be paid to the Guarantor on account of such subrogation or contribution rights at any
time when all the Guaranteed Obligations shall not have been paid in full or the Credit Agreement
or any Letter of Credit shall not have been irrevocably terminated, such amount shall be held in
trust for the benefit of the Guaranteed Parties and shall forthwith be paid to the Administrative
Agent to be credited and applied to the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms of the Credit Agreement. If (i) Guarantor shall make payment to the
Guaranteed Parties of all or any part of the Guaranteed Obligations and (ii) all the Guaranteed
Obligations (other than indemnities and other contingent obligations not then due and payable and
as to which no claim has been made as of the time of determination) shall be irrevocably paid in
full and the Credit Agreement and all Letters of Credit shall have been irrevocably terminated
(unless such Letters of Credit have been cash collateralized in accordance with the provisions of
the Credit Agreement or other arrangements with respect thereto have been made that are
satisfactory to the applicable Issuing Bank), the Guaranteed Parties will, at Guarantor’s request,
execute and deliver to Guarantor appropriate documents, without recourse and without representation
or warranty, necessary to evidence the transfer by subrogation to Guarantor of an interest in the
Guaranteed Obligations resulting from such payment by Guarantor.

          SECTION 5. Severability. Any provision of this Guaranty which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guaranty
nor consent to any departure by the Guarantor therefrom shall in any event be effective unless the
same shall be in writing executed by the Guarantor, the Administrative Agent and the Required
Lenders.

          SECTION 7. Notices. All notices and other communications provided for hereunder
shall be given in the manner specified in the Credit Agreement (i) in the case of the
Administrative Agent, at the address specified for the Administrative Agent in the Credit
Agreement, and (ii) in the case of the Guarantor, at the address specified for the Guarantor in
this Guaranty.

          SECTION 8. No Waiver; Remedies. No failure on the part of the Administrative Agent
or other Guaranteed Parties to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other right.

-4-

 

No notice to or demand on the Guarantor in any case shall entitle the Guarantor to any other
further notice or demand in any similar or other circumstances or constitute a waiver of the rights
of the Administrative Agent or other Guaranteed Parties to any other or further action in any
circumstances without notice or demand. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

          SECTION 9. Right Of Set Off. In addition to and not in limitation of all rights of
offset that the Administrative Agent or other Guaranteed Party may have under applicable law, the
Administrative Agent or other Guaranteed Parties shall, upon the occurrence of any Event of Default
and whether or not the Administrative Agent or other Guaranteed Party has made any demand or the
Guaranteed Obligations are matured, have the right to appropriate and apply to the payment of the
Guaranteed Obligations, all deposits of the Guarantor (general or special, time or demand,
provisional or final) then or thereafter held by and other indebtedness or property then or
thereafter owing by the Administrative Agent or other Guaranteed Party to the Guarantor, whether or
not related to this Guaranty or any transaction hereunder.

          SECTION 10. Continuing Guaranty; Transfer Of Obligations. This Guaranty is a
continuing guaranty and shall (i) remain in full force and effect, until payment in full of the
Guaranteed Obligations (other than indemnities and other contingent obligations not then due and
payable and as to which no claim has been made as of the time of determination), irrevocable
termination of all Letters of Credit (unless such Letters of Credit have been cash collateralized
in accordance with the provisions of the Credit Agreement or other arrangements with respect
thereto have been made that are satisfactory to the applicable Issuing Bank) and termination of the
Credit Agreement, (ii) be binding upon the Guarantor, its successors and assigns, and (iii) inure
to the benefit of and be enforceable by the Administrative Agent, for the benefit of the Guaranteed
Parties.

          SECTION 11. Governing Law; Appointment Of Agent For Service Of Process; Submission To
Jurisdiction; Waiver of Jury Trial.

          (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED
IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO
THE CONFLICT OF LAW PRINCIPLES THEREOF).

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR OTHERWISE RELATED HERETO
MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF MANHATTAN OR THE
UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY
OF THIS GUARANTY, THE GUARANTOR HEREBY CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE
JURISDICTION OF THE AFORESAID COURTS SOLELY FOR THE PURPOSE OF ADJUDICATING ITS RIGHTS OR THE

          SECTION 12. Reserved.

          SECTION 13. Judgment Currency. The Guarantor’s obligation hereunder to make payments
in the Obligation Currency shall not be discharged or satisfied by any tender or recovery pursuant
to any judgment expressed in or converted into any currency other than the Obligation Currency,
except to the extent that such tender or recovery results in the effective receipt by the
Guaranteed Parties of the full amount of the Obligation Currency expressed to be payable under this
Guaranty or the Credit Agreement. If for the purpose of obtaining or enforcing judgment against
the Guarantor in any court or in any jurisdiction, it becomes necessary to convert into or from any
currency other than the Obligation Currency (such other currency being hereinafter referred to as
the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made in
accordance with Section 10.18 of the Credit Agreement.

          SECTION 14. Automatic Acceleration in Certain Events. Upon the occurrence of an
Event of Default specified in Section 7.1(f) or (g) of the Credit Agreement, all Guaranteed
Obligations shall automatically become immediately due and payable by the Guarantor without notice
or other action on the part of the Administrative Agent or other Guaranteed Parties, and regardless
of whether payment of the Guaranteed Obligations by the Company has then been accelerated. In
addition, if any event of the types described in Section 7.1(f) or (g) of the Credit Agreement
should occur with respect to the Guarantor, then the Guaranteed Obligations shall automatically
become immediately due and payable by the Guarantor, without notice or other action on the part of
the Administrative Agent or other Guaranteed Parties, and regardless of whether payment of the
Guaranteed Obligations by the Company has then been accelerated.

          SECTION 15. Maximum Obligations. (a) It is the intent of the Guarantor and the
Guaranteed Parties that the Guarantor’s maximum obligations hereunder shall not be in excess of:

          (i) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy
Code on or within one year from the date on which any of the Guaranteed Obligations are
incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or
any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or
unenforceable against the Guarantor under (A) Section 548 of the Bankruptcy Code or (B) any
state fraudulent transfer or fraudulent conveyance act or statute applied in such case or
proceeding by virtue of Section 544 of the Bankruptcy Code; or

          (ii) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy
Code subsequent to one year from the date on which any of the Guaranteed Obligations are
incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or
any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or
unenforceable against the Guarantor under any state fraudulent transfer or fraudulent
conveyance act or statute applied in any such case or proceeding by virtue of Section 544 of
the Bankruptcy Code; or

-7-

 

          (iii) in a case or proceeding commenced by or against the Guarantor under any law,
statute or regulation other than the Bankruptcy Code (including, without limitation, any
other bankruptcy, reorganization, arrangement, moratorium, readjustment of debt,
dissolution, liquidation or similar debtor relief laws), the maximum amount which would not
otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor to the
Guaranteed Parties) to be avoidable or unenforceable against the Guarantor under such law,
statute or regulation including, without limitation, any state fraudulent transfer or
fraudulent conveyance act or statute applied in any such case or proceeding.

(The substantive laws under which the possible avoidance or unenforceability of the Guaranteed
Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) shall be
determined in any such case or proceeding shall hereinafter be referred to as the “Avoidance
Provisions”).

     (b) To the end set forth in Section 15(a), but only to the extent that the Guaranteed
Obligations would otherwise be subject to avoidance under the Avoidance Provisions if the
Guarantor is not deemed to have received valuable consideration, fair value or reasonably
equivalent value for the Guaranteed Obligations, or if the Guaranteed Obligations would
render the Guarantor insolvent, or leave the Guarantor with an unreasonably small capital to
conduct its business, or cause the Guarantor to have incurred debts (or to have intended to
have incurred debts) beyond its ability to pay such debts as they mature, in each case as of
the time any of the Guaranteed Obligations are deemed to have been incurred under the
Avoidance Provisions and after giving effect to rights of contribution, indemnity and
subrogation as between the Guarantor and the Company, the maximum Guaranteed Obligations for
which the Guarantor shall be liable hereunder shall be reduced to that amount which, after
giving effect thereto, would not cause the Guaranteed Obligations (or any other obligations
of the Guarantor to the Guaranteed Parties), as so reduced, to be subject to avoidance under
the Avoidance Provisions. This Section 15(b) is intended solely to preserve the rights of
the Guaranteed Parties hereunder to the maximum extent that would not cause the Guaranteed
Obligations of the Guarantor to be subject to avoidance under the Avoidance Provisions, and
neither the Guarantor nor any other Person shall have any right or claim under this Section
15 as against the Guaranteed Parties that would not otherwise be available to such Person
under the Avoidance Provisions.

          SECTION 16. Indemnity and Subrogation. In addition to all such rights of indemnity
and subrogation as the Guarantor may have under applicable law (but subject to Section 4 hereof),
the Company agrees that (i) in the event a payment shall be made on behalf of the Company by the
Guarantor hereunder, the Company shall indemnify the Guarantor for the full amount of such payment
and the Guarantor shall be subrogated to the rights of the person to whom such payment shall have
been made to the extent of such payment, and (ii) in the event any assets of the Guarantor shall be
sold to satisfy a claim of any Guaranteed Party hereunder, the Company shall indemnify the
Guarantor in an amount equal to the greater of the book value or the fair market value of the
assets so sold.

-8-

 

          SECTION 17. Information. The Guarantor assumes all responsibility for being and
keeping itself informed of the Company’s financial condition and assets, and of all other
circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature,
scope and extent of the risks that the Guarantor assumes and incurs hereunder, and agrees that none
of the Guaranteed Parties will have any duty to advise any of the Guarantor of information known to
it or any of them regarding such circumstances or risks.

          SECTION 18. Representations and Warranties. The Guarantor represents and warrants to
each Guaranteed Party that all representations and warranties relating to it or any of its
Subsidiaries contained in Article 5 of the Credit Agreement are true and correct in all material
respects.

          SECTION 19. Survival of Agreement. All agreements, representations and warranties
made herein shall survive the execution and delivery of this Guaranty, the Credit Agreement, the
making of the Loans, the execution and delivery of the Notes and the other Credit Documents and the
issuance of Letters of Credit.

          SECTION 20. Counterparts. This Guaranty and any amendments, waivers, consents or
supplements 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.

          SECTION 21. Currency of Payment. All payments to be made by the Guarantor hereunder
shall be made in the applicable currency as provided in Section 10.18 of the Credit Agreement and,
in the case of any required conversion of any currency, shall be determined, and the related
amounts calculated, in the manner provided in Section 10.18 of the Credit Agreement.

          SECTION 22. Termination of Guaranty. In addition to termination upon payment in full
of all of the Guaranteed Obligations (subject to the last sentence of Section 2 hereof), all
obligations of the Guarantor to the Guaranteed Parties hereunder shall terminate upon the delivery
by the Company to the Administrative Agent of a certificate stating that (i) the aggregate
principal amount of Indebtedness of all Subsidiaries outstanding pursuant to Section 6.11(j) and
(k) of the Credit Agreement, including Indebtedness of the Guarantor, is equal to or less than the
Subsidiary Debt Basket Amount, (ii) no Senior NDC Notes are outstanding and (iii) no Default or
Event of Default has occurred and is continuing. Upon compliance with the foregoing, the
Administrative Agent and the Lender shall provide written confirmation of such termination as may
be reasonably requested by the Guarantor.

REVOLVING NOTE

(Master Note)

			
	 	 	 
	U.S.$_____________
	 	_________, ____

     FOR VALUE RECEIVED, the undersigned [NOBLE CORPORATION, a Cayman Islands exempted company
limited by shares] [DESIGNATED BORROWER] (the “Borrower”), unconditionally promises to pay to the
order of ________________ (herein, together with any subsequent holder hereof, referred to as the
“Lender”) for the account of its applicable Lending Office, at the payment office of the
Administrative Agent (as hereinafter defined) on or before the Commitment Termination Date (as
defined in the Credit Agreement hereinafter described) the principal sum of ____________________
DOLLARS (U.S.$________) or, if less, the aggregate unpaid principal amount of all Revolving Loans
made by the Lender to the Borrower pursuant to the Credit Agreement, together with interest accrued
thereon, in each case as provided in the Credit Agreement. The Borrower agrees to make payments
and any required prepayments of principal on the dates and in the amounts specified in the Credit
Agreement in strict accordance with the terms thereof. The Borrower likewise agrees to pay
interest on the outstanding principal amount hereof, at such interest rates, payable at such times,
and computed in such manner, as are specified in the Credit Agreement in strict accordance with the
terms thereof. All remaining principal and accrued interest then outstanding under this Revolving
Note (this “Note”) shall be due and payable in full on the Commitment Termination Date. All
payments of principal and interest hereunder in respect of each Revolving Loan shall be made in
immediately available funds in the respective currency in which principal and interest on such
Revolving Loan are payable as provided in the Credit Agreement.

     The Lender shall record all Revolving Loans made by the Lender to the Borrower pursuant to the
Credit Agreement, and all payments of principal thereof, and, prior to any transfer hereof, shall
endorse such Revolving Loan and payments on the schedule annexed hereto and made a part hereof, or
on any continuation thereof which shall be attached hereto and made a part hereof, which
endorsement shall constitute prima facie evidence of the accuracy of the
information so endorsed; provided, however, that delay or failure of the Lender to make any such
endorsement or recordation shall not affect the obligations of the Borrower hereunder or under the
Credit Agreement with respect to the Revolving Loans evidenced hereby.

     It is the intention of the Lender to conform strictly to usury laws applicable to it.
Accordingly, if the transactions contemplated hereby or the Revolving Loans represented hereby
would be usurious as to the Lender under laws applicable to it (including the laws of the United
States of America and the State of New York or any other jurisdiction whose laws may be mandatorily
applicable to the Lender notwithstanding the other provisions of this Note or the Credit
Agreement), then, in that event, notwithstanding anything to the contrary in this Note, the Credit
Agreement or any other instrument or agreement entered into in connection with this Note, it is
agreed as follows: (i) the aggregate of all consideration which constitutes interest under laws
applicable to the Lender that is contracted for, taken, reserved, charged or received by the Lender
under this Note, the Credit Agreement, or under any of the aforesaid agreements or

 

 

instruments
entered into in connection with this Note or otherwise shall under no circumstances exceed the
Highest Lawful Rate, and any excess shall be credited by the Lender on the principal amount of this
Note (or, if the principal amount of this Note shall have been paid in full, refunded by the Lender
to the Borrower); and (ii) in the event that the maturity of this Note is accelerated by reason of
an election of the holder or holders hereof resulting from any Event of Default under the Credit
Agreement or otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under laws applicable to the Lender may never include more
than the Highest Lawful Rate, and excess interest, if any, provided for in this Note, the Credit
Agreement or otherwise shall be automatically canceled by the Lender as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the
principal amount of this Note (or if the principal amount of this Note shall have been paid in
full, refunded by the Lender to the Borrower), and in each case, to the extent permitted by
applicable law, the Lender shall not be subject to any of the penalties provided by law for
contracting for, taking, reserving, charging or receiving interest in excess of the Highest Lawful
Rate.

     “Highest Lawful Rate” shall mean the maximum nonusurious interest rate, if any, that any time
or from time to time may be contracted for, taken, reserved, charged or received on any Loans,
under laws applicable to any of the Lenders which are presently in effect or, to the extent allowed
by applicable law, under such laws which may hereafter be in effect and which allow a higher
maximum nonusurious interest rate than applicable laws now allow. Determination of the rate of
interest for the purpose of determining whether any Loans are usurious under all applicable laws
shall be made by amortizing, prorating, allocating, and spreading, in equal parts during the period
of the full stated term of the Loans, all interest at any time contracted for, taken, reserved,
charged or received from the Borrower in connection with the Loans.

     This Note is one of the Revolving Notes referred to in, and is subject to and entitled to the
benefits of, that certain Revolving Credit Agreement dated as of February 11, 2011 (as the same may
be amended, supplemented, restated or otherwise modified from time to time, the “Credit
Agreement”), entered into by and among Noble Corporation, [DESIGNATED BORROWER], the Lenders, WELLS
FARGO BANK, NATIONAL ASSOCIATION, as administrative agent for the Lenders (in such capacity, the
“Administrative Agent”) and others. Reference is hereby made to the Credit Agreement for a
statement of the prepayment rights and obligations of the Borrower and for a statement of the terms
and conditions under which the due date of this Note may be accelerated. Capitalized terms not
otherwise defined in this Note that are defined in the Credit Agreement are used in this Note with
the respective meanings assigned to such capitalized terms in the Credit Agreement as provided in
the Credit Agreement.

     Upon the occurrence and during the continuance of any Event of Default as specified in the
Credit Agreement, the principal balance hereof and the interest accrued hereon may be declared to
be forthwith due and payable in accordance with the Credit Agreement. The Borrower agrees to pay,
and indemnify the Lender against any liability for the payment of, all reasonable costs and
expenses (including reasonable attorneys’ fees) arising in connection with the enforcement by the
Lender of any of its rights under this Note or the Credit Agreement as provided in the Credit
Agreement.

-2-

 

     All parties hereto, whether as makers, endorsees, or otherwise, severally waive presentment
for prepayment, demand, protest, notice of intent to accelerate, notice of acceleration, notice of
dishonor and all other notices whatsoever in respect of this Note. TIME IS OF THE ESSENCE OF THIS

     THIS NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND

	 	________ ___, ____

     FOR VALUE RECEIVED, the undersigned [NOBLE CORPORATION, a Cayman Islands exempted company
limited by shares] [DESIGNATED BORROWER] (the “Borrower”), unconditionally promises to pay to the
order of WELLS FARGO BANK, NATIONAL ASSOCIATION (herein, together with any subsequent holder
hereof, referred to as the “Lender”) for the account of its applicable Lending Office, at the

by Credit Agreement hereinafter described, the principal sum of FIFTY MILLON DOLLARS
(U.S.$50,000,000) or, if less, the aggregate unpaid principal amount of all Swingline Loans made by
the Lender to the Borrower pursuant to the Credit Agreement, together with interest accrued
thereon, in each case as provided in the Credit Agreement. The Borrower agrees to make payments
and any required prepayments of principal on the dates and in the amounts specified in the Credit
Agreement in strict accordance with the terms thereof. The Borrower likewise agrees to pay
interest on the outstanding principal amount hereof, at such interest rates, payable at such times,
and computed in such manner, as are specified in the Credit Agreement in strict accordance with the
terms thereof. All payments of principal and interest hereunder in respect of each Swingline Loan
shall be made in immediately available funds in Dollars.

     The Lender shall record all Swingline Loans made by the Lender to the Borrower pursuant to the
Credit Agreement, and all payments of principal thereof, and, prior to any transfer hereof, shall
endorse such Swingline Loan and payments on the schedule annexed hereto and made a part hereof, or
on any continuation thereof which shall be attached hereto and made a part hereof, which
endorsement shall constitute prima facie evidence of the accuracy of the
information so endorsed; provided, however, that delay or failure of the Lender to make any such
endorsement or recordation shall not affect the obligations of the Borrower hereunder or under the
Credit Agreement with respect to the Swingline Loans evidenced hereby.

     It is the intention of the Lender to conform strictly to usury laws applicable to it.
Accordingly, if the transactions contemplated hereby or the Swingline Loans represented hereby
would be usurious as to the Lender under laws applicable to it (including the laws of the United
States of America and the State of New York or any other jurisdiction whose laws may be mandatorily
applicable to the Lender notwithstanding the other provisions of this Swingline Note (this “Note”)
or the Credit Agreement), then, in that event, notwithstanding anything to the contrary in this
Note, the Credit Agreement or any other instrument or agreement entered into in connection with
this Note, it is agreed as follows: (i) the aggregate of all consideration which constitutes
interest under laws applicable to the Lender that is contracted for, taken, reserved, charged or
received by the Lender under this Note, the Credit Agreement, or under any of the aforesaid
agreements

 

 

or instruments entered into in connection with this Note or otherwise shall under no
circumstances exceed the Highest Lawful Rate, and any excess shall be credited by the Lender on the
principal amount of this Note (or, if the principal amount of this Note shall have been paid in
full, refunded by the Lender to the Borrower); and (ii) in the event that the maturity of this Note
is accelerated by reason of an election of the holder or holders hereof resulting from any Event of
Default under the Credit Agreement or otherwise, or in the event of any required or permitted
prepayment, then such consideration that constitutes interest under laws applicable to the Lender
may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in
this Note, the Credit Agreement or otherwise shall be automatically canceled by the Lender as of
the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the
Lender on the principal amount of this Note (or if the principal amount of this Note shall have
been paid in full, refunded by the Lender to the Borrower), and in each case, to the extent
permitted by applicable law, the Lender shall not be subject to any of the penalties provided by
law for contracting for, taking, reserving, charging or receiving interest in excess of the Highest
Lawful Rate.

     “Highest Lawful Rate” shall mean the maximum nonusurious interest rate, if any, that any time
or from time to time may be contracted for, taken, reserved, charged or received on any Loans,
under laws applicable to the Lender which are presently in effect or, to the extent allowed by
applicable law, under such laws which may hereafter be in effect and which allow a higher maximum
nonusurious interest rate than applicable laws now allow. Determination of the rate of interest
for the purpose of determining whether any Swingline Loan is usurious under all applicable laws
shall be made by amortizing, prorating, allocating, and spreading, in equal parts during the period
of the full stated term of such Loan, all interest at any time contracted for, taken, reserved,
charged or received from the Borrower in connection with such Loan.

     This Note is the Swingline Note referred to in, and is subject to and entitled to the benefits
of, that certain Revolving Credit Agreement dated as of February 11, 2011 (as the same may be
amended, supplemented, restated or otherwise modified from time to time, the “Credit Agreement”),
executed by Noble Corporation, [DESIGNATED BORROWER], WELLS FARGO BANK, NATIONAL ASSOCIATION, as
administrative agent for the Lenders (in such capacity, the “Administrative Agent”) and others.
Reference is hereby made to the Credit Agreement for a statement of the prepayment rights and
obligations of the Borrower and for a statement of the terms and conditions under which the due
date of this Note may be accelerated. Capitalized terms not otherwise defined in this Note that
are defined in the Credit Agreement are used in this Note with the respective meanings assigned to
such capitalized terms in the Credit Agreement as provided in the Credit Agreement.

     Upon the occurrence and during the continuance of any Event of Default as specified in the
Credit Agreement, the principal balance hereof and the interest accrued hereon may be declared to
be forthwith due and payable in accordance with the Credit Agreement. The Borrower agrees to pay,
and indemnify the Lender against any liability for the payment of, all reasonable costs and
expenses (including reasonable attorneys’

-2-

 

fees) arising in connection with the enforcement by the
Lender of any of its rights under this Note or the Credit Agreement as provided in the Credit
Agreement.

     All parties hereto, whether as makers, endorsees, or otherwise, severally waive presentment
for prepayment, demand, protest, notice of intent to accelerate, notice of acceleration, notice of
dishonor and all other notices whatsoever in respect of this Note. TIME IS OF THE ESSENCE OF THIS
NOTE.

     THIS NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW.

FORM OF JOINDER AGREEMENT

     THIS JOINDER AGREEMENT (this “Joinder”), dated as of __________ __, 20__, is executed by [NAME
OF LENDER] (the “Additional Lender”) in favor of NOBLE CORPORATION, a Cayman Islands exempted
company limited by shares (the “Company”) and WELLS FARGO BANK, NATIONAL ASSOCIATION (“Wells
Fargo”), as administrative agent (in such capacity, the “Administrative Agent”) for the lenders
(each a “Lender” and collectively, the “Lenders”) from time to time party to the Revolving Credit
Agreement, dated as of February 11, 2011, among the Company, the Lenders, the Administrative Agent
and other parties (as amended, restated, supplemented or otherwise modified from time to time, the
“Credit Agreement”; capitalized terms used herein and not otherwise defined shall have the meanings
assigned to such terms in the Credit Agreement).

RECITALS

Pursuant to Section 2.14(a) of the Credit Agreement, the Company has elected to increase the
aggregate amount of the Commitments to an amount not to exceed $600,000,000 as of the Syndication
Closing Date and to an amount not to exceed $800,000,000 after the Syndication Closing Date.

The Additional Lender has agreed to provide a Commitment to the Company in the amount of
$_____________ (the “Additional Commitment Amount”) in accordance with the terms of Section 2.14 of
the Credit Agreement.

     NOW, THEREFORE, the Additional Lender agrees as follows:

	1.	 	Joinder. In the case that the Additional Lender is not a Lender under the Credit
Agreement, by its signature below, the Additional Lender hereby joins the Credit Agreement as
a Lender, and establishes a Commitment to the Company in the amount of the Additional
Commitment Amount. Upon acceptance of this Joinder by the Company, the Issuing Banks, the
Swingline Lender and the Administrative Agent, the Additional Lender shall be a party to, and
bound by, the Credit Agreement as a Lender thereunder. In the case that the Additional Lender
is an existing Lender under the Credit Agreement, by its signature below, the Commitment
amount of such existing Lender set forth on the signature page of the Credit Agreement shall
be deemed to be automatically updated to reflect the increase in its Commitment by the amount
of the Additional Commitment Amount for a total Commitment amount for such Lender of
$_________. Additionally, the Commitment amounts of each Lender to the Credit Agreement shall
be deemed to be automatically updated in accordance with 2.14(d) of the Credit Agreement.
	 
	2.	 	Representations and Warranties of Additional Lender. The Additional Lender
represents and warrants to the Administrative Agent and the Company that this Joinder has been
duly authorized, executed and delivered by it and that the obligations of the Additional
Lender as a “Lender” under the Credit Agreement,

 

 

	 	 	as provided by this Joinder, constitutes the legal, valid and binding obligation of the
Additional Lender.

	3.	 	Representations and Warranties of the Company; No Defaults. Each of the
representations and warranties of the Company and its Subsidiaries set forth in the Credit
Agreement (other than the representations and warranties set forth in Sections 5.4, 5.10, 5.16
and 5.17) and in the other Credit Documents (other than those that relate to the
representations and warranties set forth in Sections 5.4, 5.10, 5.16 and 5.17) shall be true
and correct in all material respects as of the time of such Additional Commitment Amount,
except to the extent that any such representation or warranty relates solely to an earlier
date, in which case it shall have been true and correct in all material respects as of such
earlier date. No Default or Event of Default shall have occurred and be continuing or would
occur as a result of any such Additional Commitment Amount.
	 
	4.	 	Effectiveness; Automatic Increase. This Joinder shall become effective when it shall
have been accepted by the Company and the Administrative Agent, at which time this Joinder
shall be deemed to be a part of and shall be subject to all the terms and conditions of the
Credit Agreement. Upon the acceptance of this Joinder by Company and the Administrative
Agent, the aggregate amount of the Commitments shall automatically be increased by an amount
equal to the Additional Commitment Amount and the signature page hereto shall automatically be
deemed a signature page to the Credit Agreement.
	 
	5.	 	Lack of Reliance on the Administrative Agent. The Additional Lender hereby appoints
Wells Fargo as the Administrative Agent, Barclays Capital, the investment banking division of
Barclays Bank PLC, and HSBC Securities (USA) Inc., as Co-Syndication Agents, [to be
determined], as Co-Documentation Agents, and Wells Fargo Securities, LLC, Barclays Capital,
the investment banking division of Barclays Bank PLC, and HSBC Securities (USA) Inc., as
Co-Arrangers under the Credit Documents and hereby authorizes the Administrative Agent to take
such action on its behalf and to exercise such powers under the Credit Documents as are
delegated to the Administrative Agent by the terms thereof, together with such powers as are
reasonably incidental thereto, and acknowledges and agrees with Article 9 of the Credit
Agreement in respect thereof. Without limiting the generality of the foregoing, the Additional
Lender acknowledges that it has, independently and without reliance upon the Administrative
Agent or any other Lender and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Joinder and become a
Lender under the Credit Agreement. The Additional Lender acknowledges that it will,
independently and without reliance upon the Administrative Agent or any other Lender and based
on such documents and information as it has deemed appropriate, continue to make its own
decisions in taking or not taking any action under or based on this Joinder, any related
agreement or any document furnished hereunder or thereunder.
	 
	6.	 	Foreign Lenders. To the extent that the Additional Lender is not a U.S. person as
defined in Section 7701(a)(30) of the Code, it certifies that it has delivered all

-2-

 

	 	 	applicable forms and perform all other actions required under Section 3.3(b) of the Credit
Agreement.

	7.	 	Governing Law. THIS JOINDER AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.
	 
	8.	 	Execution in Counterparts. This Joinder may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement.
	 
	9.	 	Notices to Additional Lender. All communications and notices to the Additional
Lender shall be given to it at the address set forth under its signature below.

EXHIBIT 2.15

MANDATORY COSTS RATE

	1.	 	The Mandatory Cost is an addition to the interest rate on each Eurocurrency Loan to
compensate Lenders for the cost of compliance with (a) the requirements of the Bank of England
and/or the Financial Services Authority (or, in either case, any other authority which
replaces all or any of its functions) or (b) the requirements of the European Central Bank.
	 
	2.	 	On the first day of each Interest Period (or as soon as possible thereafter) the
Administrative Agent shall calculate, as a percentage rate, a rate (the “Additional Cost
Rate”) for each Lender, in accordance with the paragraphs set out below. The Mandatory Cost
will be calculated by the Administrative Agent as a weighted average of the Lenders’
Additional Cost Rates (weighted in proportion to the percentage participation of each Lender
in the relevant Eurocurrency Loan) and will be expressed as a percentage rate per annum.
	 
	3.	 	The Additional Cost Rate for any Lender lending from a Lending Office in a Participating
Member State will be the percentage notified by that Lender to the Administrative Agent. This
percentage will be certified by that Lender in its notice to the Administrative Agent to be
its reasonable determination of the cost (expressed as a percentage of that Lender’s
participation in all Eurocurrency Loans made from that Lending Office) of complying with the
minimum reserve requirements of the European Central Bank in respect of loans made from that
Lending Office.
	 
	4.	 	The Additional Cost Rate for any Lender lending from a Lending Office in the United Kingdom
will be calculated by the Administrative Agent as follows:

	 	(a)	 	in relation to a sterling Eurocurrency Loan:

	 	 	 	 	 

	 

	 	AB+C(B-D)+E*0.01

	 	per cent. per annum 

	 

	 	100-(A+C)	 	 

	 	(b)	 	in relation to a Eurocurrency Loan in any currency other than sterling:

	 	 	 	 	 	 	 

	 

	 	E x 0.01	 	per cent. per annum.

	 

	 	 	300	 	 	 

Where:

	 	A 	 	is the percentage of Eligible Liabilities (assuming these to be in excess of any
stated minimum) which that Lender is from time to time required to maintain as an
interest free cash ratio deposit with the Bank of England to comply with cash ratio
requirements.

 

 

	 	B 	 	is the percentage rate of interest (excluding the Applicable Margin and the
Mandatory Cost and, if the Eurocurrency Loan is an unpaid sum, the additional rate of
interest specified in paragraph (b) Section 2.7 (Default Rate)) payable for the relevant
Interest Period on the Eurocurrency Loan.
	 
	 	C 	 	is the percentage (if any) of Eligible Liabilities which that Lender is required
from time to time to maintain as interest bearing Special Deposits with the Bank of
England.
	 
	 	D 	 	is the percentage rate per annum payable by the Bank of England to the
Administrative Agent on interest bearing Special Deposits.
	 
	 	E 	 	is designed to compensate Lenders for amounts payable under the Fees Rules and is
calculated by the Administrative Agent as being the average of the most recent rates of
charge supplied by the Reference Banks to the Administrative Agent pursuant to paragraph
7 below and expressed in pounds per £1,000,000.

	5.	 	For the purposes of this Exhibit:

	 	(a)	 	“Eligible Liabilities” and “Special Deposits” have the meanings given to
them from time to time under or pursuant to the Bank of England Act 1998 or (as may be
appropriate) by the Bank of England;
	 
	 	(b)	 	“FSA” means Financial Services Authority;
	 
	 	(c)	 	“Fees Rules” means the rules on periodic fees contained in the FSA Supervision
Manual or such other law or regulation as may be in force from time to time in respect
of the payment of fees for the acceptance of deposits;
	 
	 	(d)	 	“Fee Tariffs” means the fee tariffs specified in the Fees Rules under the
activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee
required pursuant to the Fees Rules but taking into account any applicable discount
rate);
	 
	 	(e)	 	“Participating Member State” means any member state of the European Communities
that adopts or has adopted the Euro as its lawful currency in accordance with
legislation of the European Community relating to Economic and Monetary Union;
	 
	 	(f)	 	“Reference Banks” means, in relation to LIBOR and Mandatory Cost, Wells Fargo
Bank, National Association or such other banks as may be appointed by the Administrative
Agent in consultation with the Company; and
	 
	 	(g)	 	“Tariff Base” has the meaning given to it in, and will be calculated in
accordance with, the Fees Rules.

	6.	 	In application of the above formula, A, B, C and D will be included in the formula as
percentages (i.e. 5 per cent. will be included in the formula as 5 and not as 0.05). A

2

 

	 	 	negative result obtained by subtracting D from B shall be taken as zero. The resulting
figures shall be rounded to four decimal places.
	 
	7.	 	If requested by the Administrative Agent, each Reference Bank shall, as soon as practicable
after publication by the Financial Services Authority, supply to the Administrative Agent, the
rate of charge payable by that Reference Bank to the Financial Services Authority pursuant to
the Fees Rules in respect of the relevant financial year of the Financial Services Authority
(calculated for this purpose by that Reference Bank as being the average of the Fee Tariffs
applicable to that Reference Bank for that financial year) and expressed in pounds per
£1,000,000 of the Tariff Base of that Reference Bank.
	 
	8.	 	Each Lender shall supply any information required by the Administrative Agent for the purpose
of calculating its Additional Cost Rate. In particular, but without limitation, each Lender
shall supply the following information on or prior to the date on which it becomes a Lender:

	 	(a)	 	the jurisdiction of its Lending Office; and
	 
	 	(b)	 	any other information that the Administrative Agent may reasonably require for such
purpose.

Each Lender shall promptly notify the Administrative Agent of any change to the information
provided by it pursuant to this paragraph.

	9.	 	The percentages of each Lender for the purpose of A and C above and the rates of charge of
each Reference Bank for the purpose of E above shall be determined by the Administrative Agent
based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the
assumption that, unless a Lender notifies the Administrative Agent to the contrary, each
Lender’s obligations in relation to cash ratio deposits and Special Deposits are the same as
those of a typical bank from its jurisdiction of incorporation with a Lending Office in the
same jurisdiction as its Lending Office.
	 
	10.	 	The Administrative Agent shall have no liability to any person if such determination results
in an Additional Cost Rate which over or under compensates any Lender and shall be entitled to
assume that the information provided by any Lender or Reference Bank pursuant to paragraphs 3,
7 and 8 above is true and correct in all respects.
	 
	11.	 	The Administrative Agent shall distribute the additional amounts received as a result of the
Mandatory Cost to the Lenders on the basis of the Additional Cost Rate for each Lender based
on the information provided by each Lender and each Reference Bank pursuant to paragraphs 3, 7
and 8 above.

3

 

	12.	 	Any determination by the Administrative Agent pursuant to this Exhibit in relation to a
formula, the Mandatory Cost, an Additional Cost Rate or any amount payable to a Lender shall,
in the absence of manifest error, be conclusive and binding on all parties.
	 
	13.	 	The Administrative Agent may from time to time, after consultation with the Company and the
Lenders, determine and notify to all parties any amendments which are required to be made to
this Exhibit in order to comply with any change in law, regulation or any requirements from
time to time imposed by the Bank of England, the Financial Services Authority or the European
Central Bank (or, in any case, any other authority which replaces all or any of its functions)
and any such determination shall, in the absence of manifest error, be conclusive and binding
on all parties.

FORM OF COMPANY GUARANTY

          THIS GUARANTY AGREEMENT (this “Guaranty”), dated as of [date] is made by Noble Corporation, a
Cayman Islands exempted company limited by shares (the “Company” or the “Guarantor”), in favor of
(i) the Lenders (as defined in the Credit Agreement) (as hereinafter defined), (ii) Wells Fargo
Bank, National Association, in its capacity as Administrative Agent (as defined in the Credit
Agreement), (iii) Wells Fargo Bank, National Association, in its capacity as the Swingline Lender
(as defined in the Credit Agreement), (iv) the Other Agents (as defined in the Credit Agreement)
and (v) the Issuing Banks (as defined in the Credit Agreement) (the Lenders, the Administrative
Agent, the Other Agents, the Swingline Lender and the Issuing Banks are each individually referred
to herein as a “Guaranteed Party”, and collectively, as the “Guaranteed Parties”);

WITNESSETH:

          WHEREAS, the Company, the Lenders, the Administrative Agent, the Swingline Lender and the
Issuing Banks are parties to a certain Revolving Credit Agreement dated as of February 11, 2011 (as
the same may hereafter be amended, restated, supplemented or otherwise modified from time to time,
the “Credit Agreement”; terms defined therein and not otherwise defined herein being used herein as
therein defined);

          WHEREAS, the Company has designated [DESIGNATED BORROWER] as the Designated Borrower under
Section 2.18 of the Credit Agreement;

          WHEREAS, the Company owns, directly or indirectly, all or a majority of all outstanding
capital stock or other equity interests of the Designated Borrower;

          WHEREAS, it is a requirement under Section 2.18 of the Credit Agreement, as a condition to the
making of Loans and the issuance of Letters of Credit to the Designated Borrower, that the
Guarantor execute and deliver this Guaranty, and the Guarantor desires to execute and deliver this
Guaranty to satisfy such requirement;

          NOW, THEREFORE, in consideration of the premises and in order to satisfy the requirements of
the Credit Agreement, and for other good and valuable consideration, the Guarantor hereby agrees as
follows:

          SECTION 1. Guaranty. The Guarantor hereby, irrevocably and unconditionally,
guarantees the punctual payment when due, in lawful money of the United States of America or in
another currency as provided for in Section 3.2(a) of the Credit Agreement (the “Obligation
Currency”), whether at stated maturity, by acceleration or otherwise, of the Loans, L/C
Obligations, and all other Obligations owing by the Designated Borrower to the Lenders, the
Administrative Agent, the Swingline Lender, the Issuing Banks and

 

 

Other Agents, or any of them, under the Credit Agreement, the Notes, and the other Credit
Documents, including all renewals, extensions, modifications and refinancings thereof, now or
hereafter owing, whether for principal, interest, fees, expenses, indemnities, reimbursement
obligations or otherwise, and any and all reasonable out-of-pocket expenses (including reasonable
attorneys’ fees and expenses) incurred by the Lenders or the Administrative Agent in enforcing any
rights under this Guaranty (collectively, the “Guaranteed Obligations”), including without
limitation, all interest which, but for the filing of a petition in bankruptcy, would accrue on any
principal portion of the Guaranteed Obligations. Any and all payments by the Guarantor hereunder
shall be made in the Obligation Currency free and clear of and without deduction for any set-off,
counterclaim, or withholding so that, in each case, each Guaranteed Party will receive, after
giving effect to any Indemnified Taxes (as such term is defined in the Credit Agreement), the full
amount, in the Obligation Currency, that it would otherwise be entitled to receive with respect to
the Guaranteed Obligations (but without duplication of amounts for Indemnified Taxes already
included in the Guaranteed Obligations). The Guarantor acknowledges and agrees that this is a
guarantee of payment when due, and not of collection, and that this Guaranty may be enforced up to
the full amount of the Guaranteed Obligations without proceeding against the Designated Borrower,
against any security for the Guaranteed Obligations, against any other Person or under any other
guaranty covering any portion of the Guaranteed Obligations.

          SECTION 2. Guaranty Absolute. The Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of
such terms or the rights of any Guaranteed Party with respect thereto. The liability of the
Guarantor under this Guaranty shall be absolute and unconditional in accordance with its terms and
shall remain in full force and effect without regard to, and shall not be released, suspended,
discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever,
including, without limitation, the following (whether or not the Guarantor consents thereto or has
notice thereof):

     (a) any change in the time, place or manner of payment of, or in any other term of, all
or any of the Guaranteed Obligations, any waiver, indulgence, renewal, extension, amendment
or modification of or addition, consent or supplement to or deletion from or any other
action or inaction under or in respect of the Credit Agreement or the other Credit
Documents, or any other documents, instruments or agreements relating to the Guaranteed
Obligations or any other instrument or agreement referred to therein or any assignment or
transfer of any thereof;

     (b) any lack of validity or enforceability of the Credit Agreement or the other Credit
Documents, or any other document, instrument or agreement referred to therein or any
assignment or transfer of any thereof;

     (c) any furnishing to the Guaranteed Parties of any additional security or additional
guaranty for the Guaranteed Obligations, or any sale, exchange, release or surrender of, or
realization on, any security or guaranty for the Guaranteed Obligations;

-2-

 

     (d) any settlement or compromise of any of the Guaranteed Obligations, any security
therefor, or any liability of any other party with respect to the Guaranteed Obligations, or
any subordination of the payment of the Guaranteed Obligations to the payment of any other
liability of the Designated Borrower;

     (e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution,
liquidation or other like proceeding relating to the Guarantor, the Designated Borrower or
any other Person, or any action taken with respect to this Guaranty by any trustee or
receiver, or by any court, in any such proceeding;

     (f) any nonperfection of any security interest or lien on any collateral, or any
amendment or waiver of or consent to departure from any guaranty or security, for all or any
of the Guaranteed Obligations;

     (g) any application of sums paid by the Designated Borrower or any other Person with
respect to the liabilities of the Designated Borrower to the Guaranteed Parties, regardless
of what liabilities of the Designated Borrower remain unpaid;

     (h) any act or failure to act by any Guaranteed Party which may adversely affect the
Guarantor’s subrogation rights, if any, against the Designated Borrower to recover payments
made under this Guaranty; and

     (i) any other circumstance which might otherwise constitute a defense available to, or
a discharge of, the Guarantor.

If claim is ever made upon any Guaranteed Party for repayment or recovery of any amount or amounts
received in payment or on account of any of the Guaranteed Obligations, and any Guaranteed Party
repays all or part of said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over the Guaranteed Party or any of its property, or (b)
any settlement or compromise of any such claim effected by the Guaranteed Party with any such
claimant (including, without limitation, the Designated Borrower or a trustee in bankruptcy for the
Designated Borrower), then and in such event the Guarantor agrees that any such judgment, decree,
order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or
the cancellation of the Credit Agreement, the other Credit Documents, or any other instrument
evidencing any liability of the Designated Borrower, and the Guarantor shall be and remain liable
to the Guaranteed Party for the amounts so repaid or recovered to the same extent as if such amount
had never originally been paid to the Guaranteed Party.

          SECTION 3. Waiver. The Guarantor hereby waives (a) notice of acceptance of this
Guaranty, (b) notice of the incurrence of any Guaranteed Obligation, (c) notice of acceleration,
(d) notice of intent to accelerate, (e) any requirement that any of the Guaranteed Parties
institute suit, collection proceedings or take any other action to collect any of the Guaranteed
Obligations, (f) diligence and promptness, (g) notice of presentment, demand of payment or protest,
(h) notice of dishonor or nonpayment, (i) notice of suit or taking of other action by the
Guaranteed Parties against the Designated Borrower and (j) any other notice to the

-3-

 

Designated Borrower or any other party liable with respect to the Guaranteed Obligations
(including, without limitation, any other Person executing a guaranty of the obligations of the
Designated Borrower).

          SECTION 4. Subrogation. The Guarantor will not exercise any rights against the
Designated Borrower which it may acquire by way of subrogation or contribution, by any payment made
hereunder or otherwise, until all the Guaranteed Obligations (other than indemnities and other
contingent obligations not then due and payable and as to which no claim has been made as of the
time of determination) shall have been irrevocably paid in full and the Credit Agreement and all
Letters of Credit shall have been irrevocably terminated (unless such Letters of Credit have been
cash collateralized in accordance with the provisions of the Credit Agreement or other arrangements
with respect thereto have been made that are satisfactory to the applicable Issuing Bank). If any
amount shall be paid to the Guarantor on account of such subrogation or contribution rights at any
time when all the Guaranteed Obligations shall not have been paid in full or the Credit Agreement
or any Letter of Credit shall not have been irrevocably terminated, such amount shall be held in
trust for the benefit of the Guaranteed Parties and shall forthwith be paid to the Administrative
Agent to be credited and applied to the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms of the Credit Agreement. If (i) Guarantor shall make payment to the
Guaranteed Parties of all or any part of the Guaranteed Obligations and (ii) all the Guaranteed
Obligations (other than indemnities and other contingent obligations not then due and payable and
as to which no claim has been made as of the time of determination) shall be irrevocably paid in
full and the Credit Agreement and all Letters of Credit shall have been irrevocably terminated
(unless such Letters of Credit have been cash collateralized in accordance with the provisions of
the Credit Agreement or other arrangements with respect thereto have been made that are
satisfactory to the applicable Issuing Bank), the Guaranteed Parties will, at Guarantor’s request,
execute and deliver to Guarantor appropriate documents, without recourse and without representation
or warranty, necessary to evidence the transfer by subrogation to Guarantor of an interest in the
Guaranteed Obligations resulting from such payment by Guarantor.

          SECTION 5. Severability. Any provision of this Guaranty which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guaranty
nor consent to any departure by the Guarantor therefrom shall in any event be effective unless the
same shall be in writing executed by the Guarantor, the Administrative Agent and the Required
Lenders.

          SECTION 7. Notices. All notices and other communications provided for hereunder
shall be given in the manner specified in the Credit Agreement (i) in the case of the
Administrative Agent, at the address specified for the Administrative Agent in the Credit
Agreement, and (ii) in the case of the Guarantor, at the address specified for the Guarantor in
this Guaranty.

-4-

 

          SECTION 8. No Waiver; Remedies. No failure on the part of the Administrative Agent
or other Guaranteed Parties to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other right. No notice to or
demand on the Guarantor in any case shall entitle the Guarantor to any other further notice or
demand in any similar or other circumstances or constitute a waiver of the rights of the
Administrative Agent or other Guaranteed Parties to any other or further action in any
circumstances without notice or demand. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

          SECTION 9. Right of Set Off. In addition to and not in limitation of all rights of
offset that the Administrative Agent or other Guaranteed Party may have under applicable law, the
Administrative Agent or other Guaranteed Parties shall, upon the occurrence of any Event of Default
and whether or not the Administrative Agent or other Guaranteed Party has made any demand or the
Guaranteed Obligations are matured, have the right to appropriate and apply to the payment of the
Guaranteed Obligations, all deposits of the Guarantor (general or special, time or demand,
provisional or final) then or thereafter held by and other indebtedness or property then or
thereafter owing by the Administrative Agent or other Guaranteed Party to the Guarantor, whether or
not related to this Guaranty or any transaction hereunder.

          SECTION 10. Continuing Guaranty; Transfer Of Obligations. This Guaranty is a
continuing guaranty and shall (i) remain in full force and effect, until payment in full of the
Guaranteed Obligations (other than indemnities and other contingent obligations not then due and
payable and as to which no claim has been made as of the time of determination), irrevocable
termination of all Letters of Credit (unless such Letters of Credit have been cash collateralized
in accordance with the provisions of the Credit Agreement or other arrangements with respect
thereto have been made that are satisfactory to the applicable Issuing Bank) and termination of the
Credit Agreement, (ii) be binding upon the Guarantor, its successors and assigns, and (iii) inure
to the benefit of and be enforceable by the Administrative Agent, for the benefit of the Guaranteed
Parties.

          SECTION 11. Governing Law; Appointment Of Agent For Service Of Process; Submission To
Jurisdiction; Waiver of Jury Trial.

          (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED
IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO
THE CONFLICT OF LAW PRINCIPLES THEREOF).

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR OTHERWISE RELATED HERETO
MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF MANHATTAN OR THE
UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY

RESPECT OF ITS PROPERTY, TO THE JURISDICTION OF THE AFORESAID COURTS SOLELY FOR THE PURPOSE OF
ADJUDICATING ITS RIGHTS OR THE RIGHTS OF THE ADMINISTRATIVE AGENT AND OTHER GUARANTEED PARTIES WITH
RESPECT TO THIS GUARANTY OR ANY DOCUMENT RELATED HERETO. THE GUARANTOR HEREBY IRREVOCABLY
DESIGNATES CT CORPORATION SYSTEM, 111 8TH AVENUE, NEW YORK, NEW YORK 10011, AS THE DESIGNEE,
APPOINTEE AND AGENT OF THE GUARANTOR TO RECEIVE, FOR AND ON BEHALF OF THE GUARANTOR, SERVICE OF
PROCESS IN SUCH JURISDICTION IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY
DOCUMENT RELATED HERETO AND SUCH SERVICE SHALL BE DEEMED COMPLETED THIRTY DAYS AFTER MAILING
THEREOF TO SAID AGENT. IT IS UNDERSTOOD THAT A COPY OF SUCH PROCESS SERVED ON SUCH AGENT WILL BE
PROMPTLY FORWARDED BY MAIL TO THE GUARANTOR AT ITS ADDRESS SET FORTH HEREIN, BUT THE FAILURE OF THE
GUARANTOR TO RECEIVE SUCH COPY SHALL NOT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, AFFECT IN ANY
WAY THE SERVICE OF SUCH PROCESS. IF FOR ANY REASON SERVICE OF PROCESS CANNOT PROMPTLY BE MADE ON
EITHER SUCH LOCAL AGENT, THE GUARANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF
ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF
BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE COMPANY AT ITS SAID ADDRESS, SUCH SERVICE
TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. THE GUARANTOR HEREBY IRREVOCABLY WAIVES ANY

GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS IN RESPECT OF THIS GUARANTY
OR ANY DOCUMENT RELATED THERETO. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT
TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
PROCEED AGAINST THE GUARANTOR IN ANY OTHER JURISDICTION.

          (c) TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE GUARANTOR HEREBY IRREVOCABLY WAIVES ALL
RIGHT OF TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN CONNECTION
WITH THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT OR ANY MATTER ARISING IN CONNECTION HEREUNDER OR
THEREUNDER.

          (d) EACH OF THE GUARANTOR AND THE GUARANTEED PARTIES IRREVOCABLY CONSENTS TO SERVICE OF
PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 10.7 OF THE CREDIT AGREEMENT. NOTHING IN
THIS GUARANTY WILL AFFECT THE RIGHT OF ANY SUCH PARTY TO SERVE PROCESS IN ANY MANNER PERMITTED BY
APPLICABLE LAW.

-6-

 

          (E) EACH OF THE GUARANTOR AND THE GUARANTEED PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVES, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THIS SECTION 11 OR OTHERWISE RELATING TO THE
CREDIT DOCUMENTS ANY PUNITIVE DAMAGES.

          SECTION 12. Reserved.

          SECTION 13. Judgment Currency. The Guarantor’s obligation hereunder to make payments
in the Obligation Currency shall not be discharged or satisfied by any tender or recovery pursuant
to any judgment expressed in or converted into any currency other than the Obligation Currency,
except to the extent that such tender or recovery results in the effective receipt by the
Guaranteed Parties of the full amount of the Obligation Currency expressed to be payable under this
Guaranty or the Credit Agreement. If for the purpose of obtaining or enforcing judgment against
the Guarantor in any court or in any jurisdiction, it becomes necessary to convert into or from any
currency other than the Obligation Currency (such other currency being hereinafter referred to as
the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made in
accordance with Section 10.18 of the Credit Agreement.

          SECTION 14. Automatic Acceleration in Certain Events. Upon the occurrence of an
Event of Default specified in Section 7.1(f) or (g) of the Credit Agreement, all Guaranteed
Obligations shall automatically become immediately due and payable by the Guarantor without notice
or other action on the part of the Administrative Agent or other Guaranteed Parties, and regardless
of whether payment of the Guaranteed Obligations by the Designated Borrower has then been
accelerated. In addition, if any event of the types described in Section 7.1(f) or (g) of the
Credit Agreement should occur with respect to the Guarantor, then the Guaranteed Obligations shall
automatically become immediately due and payable by the Guarantor, without notice or other action
on the part of the Administrative Agent or other Guaranteed Parties, and regardless of whether
payment of the Guaranteed Obligations by the Designated Borrower has then been accelerated.

          SECTION 15. Maximum Obligations. (a) It is the intent of the Guarantor and the
Guaranteed Parties that the Guarantor’s maximum obligations hereunder shall not be in excess of:

     (i) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy
Code on or within one year from the date on which any of the Guaranteed Obligations are
incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or
any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or
unenforceable against the Guarantor under (A) Section 548 of the Bankruptcy Code or (B) any
state fraudulent transfer or fraudulent conveyance act or statute applied in such case or
proceeding by virtue of Section 544 of the Bankruptcy Code; or

-7-

 

     (ii) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy
Code subsequent to one year from the date on which any of the Guaranteed Obligations are
incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or
any other obligations of the Guarantor to the Guaranteed Parties) to be avoidable or
unenforceable against the Guarantor under any state fraudulent transfer or fraudulent
conveyance act or statute applied in any such case or proceeding by virtue of Section 544 of
the Bankruptcy Code; or

     (iii) in a case or proceeding commenced by or against the Guarantor under any law,
statute or regulation other than the Bankruptcy Code (including, without limitation, any
other bankruptcy, reorganization, arrangement, moratorium, readjustment of debt,
dissolution, liquidation or similar debtor relief laws), the maximum amount which would not
otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor to the
Guaranteed Parties) to be avoidable or unenforceable against the Guarantor under such law,
statute or regulation including, without limitation, any state fraudulent transfer or
fraudulent conveyance act or statute applied in any such case or proceeding.

(The substantive laws under which the possible avoidance or unenforceability of the Guaranteed
Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) shall be
determined in any such case or proceeding shall hereinafter be referred to as the “Avoidance
Provisions”).

     (b) To the end set forth in Section 15(a), but only to the extent that the Guaranteed
Obligations would otherwise be subject to avoidance under the Avoidance Provisions if the
Guarantor is not deemed to have received valuable consideration, fair value or reasonably
equivalent value for the Guaranteed Obligations, or if the Guaranteed Obligations would
render the Guarantor insolvent, or leave the Guarantor with an unreasonably small capital to
conduct its business, or cause the Guarantor to have incurred debts (or to have intended to
have incurred debts) beyond its ability to pay such debts as they mature, in each case as of
the time any of the Guaranteed Obligations are deemed to have been incurred under the
Avoidance Provisions and after giving effect to rights of contribution, indemnity and
subrogation as between the Guarantor and the Designated Borrower, the maximum Guaranteed
Obligations for which the Guarantor shall be liable hereunder shall be reduced to that
amount which, after giving effect thereto, would not cause the Guaranteed Obligations (or
any other obligations of the Guarantor to the Guaranteed Parties), as so reduced, to be
subject to avoidance under the Avoidance Provisions. This Section 15(b) is intended solely
to preserve the rights of the Guaranteed Parties hereunder to the maximum extent that would
not cause the Guaranteed Obligations of the Guarantor to be subject to avoidance under the
Avoidance Provisions, and neither the Guarantor nor any other Person shall have any right or
claim under this Section 15 as against the Guaranteed Parties that would not otherwise be
available to such Person under the Avoidance Provisions.

-8-

 

          SECTION 16. Indemnity and Subrogation. In addition to all such rights of indemnity
and subrogation as the Guarantor may have under applicable law (but subject to Section 4 hereof),
the Designated Borrower agrees that (i) in the event a payment shall be made on behalf of the
Designated Borrower by the Guarantor hereunder, the Designated Borrower shall indemnify the
Guarantor for the full amount of such payment and the Guarantor shall be subrogated to the rights
of the person to whom such payment shall have been made to the extent of such payment, and (ii) in
the event any assets of the Guarantor shall be sold to satisfy a claim of any Guaranteed Party
hereunder, the Designated Borrower shall indemnify the Guarantor in an amount equal to the greater
of the book value or the fair market value of the assets so sold.

          SECTION 17. Information. The Guarantor assumes all responsibility for being and
keeping itself informed of the Designated Borrower’s financial condition and assets, and of all
other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the
nature, scope and extent of the risks that the Guarantor assumes and incurs hereunder, and agrees
that none of the Guaranteed Parties will have any duty to advise any of the Guarantor of
information known to it or any of them regarding such circumstances or risks.

          SECTION 18. Representations and Warranties. The Guarantor represents and warrants to
each Guaranteed Party that all representations and warranties relating to it or any of its
Subsidiaries contained in Article 5 of the Credit Agreement are true and correct in all material
respects

          SECTION 19. Survival of Agreement. All agreements, representations and warranties
made herein shall survive the execution and delivery of this Guaranty, the Credit Agreement, the
making of the Loans, the execution and delivery of the Notes and the other Credit Documents and the
issuance of Letters of Credit.

          SECTION 20. Counterparts. This Guaranty and any amendments, waivers, consents or
supplements 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.

          SECTION 21. Currency of Payment. All payments to be made by the Guarantor hereunder
shall be made in the applicable currency as provided in Section 10.18 of the Credit Agreement and,
in the case of any required conversion of any currency, shall be determined, and the related
amounts calculated, in the manner provided in Section 10.18 of the Credit Agreement.

EXHIBIT 6.11

SUBSIDIARY GUARANTY AGREEMENT

          THIS SUBSIDIARY GUARANTY AGREEMENT (this “Guaranty”), dated as of __________________, ______,
made by each of the undersigned Subsidiaries of Noble Corporation, a Cayman Islands exempted
company limited by shares (the “Company”; each undersigned Subsidiary of the Company being herein
referred to individually as a “Guarantor” and collectively as the “Guarantors”), in favor of (i)
the banks and other financial institutions that are parties to the Credit Agreement (as hereinafter
defined) and each assignee thereof becoming a “Lender” as provided therein (the “Lenders”), (ii)
Wells Fargo Bank, National Association, in its capacity as administrative agent (the
“Administrative Agent”) under the terms of the Credit Agreement, (iii) Wells Fargo Bank, National
Association, in its capacity as the Swingline Lender (as defined in the Credit Agreement) under the
terms of the Credit Agreement, and (iv) the Other Agents and the Issuing Banks (as such terms are
defined in the Credit Agreement) under the terms of the Credit Agreement (the Lenders, the
Administrative Agent, the Swingline Lender, the Other Agents, and the Issuing Banks being
collectively referred to herein as the “Guaranteed Parties”);

WITNESSETH:

          WHEREAS, the Company, the Lenders and the Administrative Agent have entered into a certain
Revolving Credit Agreement dated as of February 11, 2011 (as the same may hereafter be amended,
restated, supplemented or otherwise modified from time to time, and including all schedules,
riders, and supplements thereto, the “Credit Agreement”; terms defined therein and not otherwise
defined herein being used herein as therein defined);

          WHEREAS, the Company owns, directly or indirectly, all or a majority of all outstanding
capital stock or other equity interests of each Guarantor;

          WHEREAS, it is a requirement under Section 6.11(k) of the Credit Agreement that each Guarantor
execute and deliver this Guaranty, and each Guarantor desires to execute and deliver this Guaranty
to satisfy such requirement; and

          WHEREAS, this Guaranty and the obligation of each Guarantor shall remain in full force and
effect until termination of this Guaranty as provided in Section 23 below or as otherwise provided
in Section 10(i) below;

          NOW, THEREFORE, in consideration of the premises and in order to satisfy the requirements of
the Credit Agreement, and for Ten Dollars ($10.00) and other good and valuable consideration, each
Guarantor hereby jointly and severally agrees as follows:

 

 

          SECTION 1. Guaranty. Subject to Section 23 below, each Guarantor hereby jointly and
severally, irrevocably and unconditionally, guarantees the punctual payment when due, in lawful
money of the United States of America or in another currency as provided for in Section 3.2(a) of
the Credit Agreement (the “Obligation Currency”), whether at stated maturity, by acceleration or
otherwise, of the Loans, L/C Obligations, and all other Obligations owing by the Company to the
Lenders, the Administrative Agent, the Swingline Lender, the Issuing Banks and Other Agents, or
any of them, under the Credit Agreement, the Notes, and the other Credit Documents, including all
renewals, extensions, modifications and refinancings thereof, now or hereafter owing, whether for
principal, interest, fees, expenses or otherwise, and any and all reasonable out-of-pocket expenses
(including reasonable attorneys’ fees and expenses) incurred by the Lenders or the Administrative
Agent in enforcing any rights under this Guaranty (collectively, the “Guaranteed Obligations”),
including without limitation, all interest which, but for the filing of a petition in bankruptcy,
would accrue on any principal portion of the Guaranteed Obligations. Any and all payments by each
Guarantor hereunder shall be made in the Obligation Currency free and clear of and without
deduction for any set-off, counterclaim, or withholding so that, in each case, each Guaranteed
Party will receive, after giving effect to any Indemnified Taxes (as such term is defined in the
Credit Agreement), the full amount, in the Obligation Currency, that it would otherwise be entitled
to receive with respect to the Guaranteed Obligations (but without duplication of amounts for
Indemnified Taxes already included in the Guaranteed Obligations). Each Guarantor acknowledges and
agrees that this is a guarantee of payment when due, and not of collection, and that this Guaranty
may be enforced up to the full amount of the Guaranteed Obligations without proceeding against the
Company, against any security for the Guaranteed Obligations, against any other Guarantor or under
any other guaranty covering any portion of the Guaranteed Obligations.

          SECTION 2. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of
such terms or the rights of any Guaranteed Party with respect thereto. Subject to Section 23
below, the liability of each Guarantor under this Guaranty shall be absolute and unconditional in
accordance with its terms and shall remain in full force and effect without regard to, and shall
not be released, suspended, discharged, terminated or otherwise affected by, any circumstance or
occurrence whatsoever, including, without limitation, the following (whether or not such Guarantor
consents thereto or has notice thereof):

     (a) any change in the time, place or manner of payment of, or in any other term of, all
or any of the Guaranteed Obligations, any waiver, indulgence, renewal, extension, amendment
or modification of or addition, consent or supplement to or deletion from or any other
action or inaction under or in respect of the Credit Agreement or the other Credit
Documents, or any other documents, instruments or agreements relating to the Guaranteed
Obligations or any other instrument or agreement referred to therein or any assignment or
transfer of any thereof;

     (b) any lack of validity or enforceability of the Credit Agreement or the other Credit
Documents, or any other document, instrument or agreement referred to therein or any
assignment or transfer of any thereof;

-2-

 

     (c) any furnishing to the Guaranteed Parties of any additional security for the
Guaranteed Obligations, or any sale, exchange, release or surrender of, or realization on,
any security for the Guaranteed Obligations;

     (d) any settlement or compromise of any of the Guaranteed Obligations, any security
therefor, or any liability of any other party with respect to the Guaranteed Obligations, or
any subordination of the payment of the Guaranteed Obligations to the payment of any other
liability of the Company;

     (e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution,
liquidation or other like proceeding relating to any Guarantor or the Company, or any action
taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such
proceeding;

     (f) any nonperfection of any security interest or lien on any collateral, or any
amendment or waiver of or consent to departure from any guaranty or security, for all or any
of the Guaranteed Obligations;

     (g) any application of sums paid by the Company or any other Person with respect to the
liabilities of the Company to the Guaranteed Parties, regardless of what liabilities of the
Company remain unpaid;

     (h) any act or failure to act by any Guaranteed Party which may adversely affect a
Guarantor’s subrogation rights, if any, against the Company to recover payments made under
this Guaranty; and

     (i) any other circumstance which might otherwise constitute a defense available to, or
a discharge of, any Guarantor.

If claim is ever made upon any Guaranteed Party for repayment or recovery of any amount or amounts
received in payment or on account of any of the Guaranteed Obligations, and any Guaranteed Party
repays all or part of said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over the Guaranteed Party or any of its property, or (b)
any settlement or compromise of any such claim effected by the Guaranteed Party with any such
claimant (including the Company or a trustee in bankruptcy for the Company), then and in such event
each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be
binding on it, notwithstanding any revocation hereof or the cancellation of the Credit Agreement,
the other Credit Documents, or any other instrument evidencing any liability of the Company, and
each Guarantor shall be and remain liable to the Guaranteed Party for the amounts so repaid or
recovered to the same extent as if such amount had never originally been paid to the Guaranteed
Party.

          SECTION 3. Waiver. Each Guarantor hereby waives (a) notice of acceptance of this
Guaranty, (b) notice of the incurrence of any Guaranteed Obligation, (c) notice of acceleration,
(d) notice of intent to accelerate, (e) any requirement that any of the Guaranteed

-3-

 

Parties institute suit, collection proceedings or take any other action to collect any of the
Guaranteed Obligations, (f) diligence and promptness, (g) notice of presentment, demand of payment
or protest, (h) notice of dishonor or nonpayment, (i) notice of suit or taking of other action by
the Guaranteed Parties against the Company and (j) any other notice to the Company or any other
party liable with respect to the Guaranteed Obligations (including, without limitation, any other
Person executing a guaranty of the obligations of the Company).

          SECTION 4. Subrogation. No Guarantor will exercise any rights against the Company
which it may acquire by way of subrogation or contribution, by any payment made hereunder or
otherwise, until all the Guaranteed Obligations (other than indemnities and other contingent
obligations not then due and payable and as to which no claim has been made as of the time of
determination) shall have been irrevocably paid in full and the Credit Agreement and all Letters of
Credit shall have been irrevocably terminated (unless such Letters of Credit have been cash
collateralized in accordance with the provisions of the Credit Agreement or other arrangements with
respect thereto have been made that are satisfactory to the applicable Issuing Bank). If any
amount shall be paid to a Guarantor on account of such subrogation or contribution rights at any
time when all the Guaranteed Obligations shall not have been paid in full, or the Credit Agreement
or any Letter of Credit shall not have been irrevocably terminated, such amount shall be held in
trust for the benefit of the Guaranteed Parties and shall forthwith be paid to the Administrative
Agent to be credited and applied to the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms of the Credit Agreement. If (i) a Guarantor shall make payment to the
Guaranteed Parties of all or any part of the Guaranteed Obligations and (ii) all the Guaranteed
Obligations (other than indemnities and other contingent obligations not then due and payable and
as to which no claim has been made as of the time of determination) shall be irrevocably paid in
full and the Credit Agreement and all Letters of Credit irrevocably terminated (unless such Letters
of Credit have been cash collateralized in accordance with the provisions of the Credit Agreement
or other arrangements with respect thereto have been made that are satisfactory to the applicable
Issuing Bank), the Guaranteed Parties will, at such Guarantor’s request, execute and deliver to the
Guarantor appropriate documents, without recourse and without representation or warranty, necessary
to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed
Obligations resulting from such payment by such Guarantor.

          SECTION 5. Severability. Any provision of this Guaranty which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guaranty
nor consent to any departure by a Guarantor therefrom shall in any event be effective unless the
same shall be in writing executed by such Guarantor, the Administrative Agent and the Required
Lenders.

          SECTION 7. Notices. All notices and other communications provided for hereunder shall
be given in the manner specified in the Credit Agreement (i) in the case of the

-4-

 

Administrative Agent, at the address specified for the Administrative Agent in the Credit
Agreement, and (ii) in the case of the Guarantors, at the respective addresses specified for such
Guarantors in this Guaranty.

          SECTION 8. No Waiver; Remedies. No failure on the part of the Administrative Agent or
other Guaranteed Parties to exercise, and no delay in exercising, any right hereunder shall operate
as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any
other or further exercise thereof or the exercise of any other right. No notice to or demand on
any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in any
similar or other circumstances or constitute a waiver of the rights of the Administrative Agent or
other Guaranteed Parties to any other or further action in any circumstances without notice or
demand. The remedies herein provided are cumulative and not exclusive of any remedies provided by
law.

          SECTION 9. Right Of Set Off. In addition to and not in limitation of all rights of
offset that the Administrative Agent or other Guaranteed Parties may have under applicable law, the
Administrative Agent or other Guaranteed Parties shall, upon the occurrence of any Event of Default
and whether or not the Administrative Agent or other Guaranteed Parties have made any demand or the
Guaranteed Obligations are matured, have the right to appropriate and apply to the payment of the
Guaranteed Obligations, all deposits of any Guarantor (general or special, time or demand,
provisional or final) then or thereafter held by and other indebtedness or property then or
thereafter owing by the Administrative Agent or other Guaranteed Parties to any Guarantor, whether
or not related to this Guaranty or any transaction hereunder.

          SECTION 10. Continuing Guaranty; Transfer Of Obligations. This Guaranty is a
continuing guaranty and shall (i) remain in full force and effect, subject to Section 23 below,
until payment in full of the Guaranteed Obligations (other than indemnities and other contingent
obligations not then due and payable and as to which no claim has been made as of the time of
determination), irrevocable termination of all Letters of Credit (unless such Letters of Credit
have been cash collateralized in accordance with the provisions of the Credit Agreement or other
arrangements with respect thereto have been made that are satisfactory to the applicable Issuing
Bank) and the termination of the Credit Agreement, (ii) be binding upon each Guarantor, its
successors and assigns, and (iii) inure to the benefit of and be enforceable by the Administrative
Agent, for the benefit of the Guaranteed Parties.

          SECTION 11. Governing Law; Appointment Of Agent For Service Of Process; Submission To
Jurisdiction; Waiver of Jury Trial.

          (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED
IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO
THE CONFLICT OF LAW PRINCIPLES THEREOF).

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR OTHERWISE RELATED HERETO
MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF

-5-

 

MANHATTAN OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY
EXECUTION AND DELIVERY OF THIS GUARANTY, EACH GUARANTOR HEREBY CONSENTS, FOR ITSELF AND IN RESPECT
OF ITS PROPERTY, TO THE JURISDICTION OF THE AFORESAID COURTS SOLELY FOR THE PURPOSE OF ADJUDICATING
ITS RIGHTS OR THE RIGHTS OF THE ADMINISTRATIVE AGENT AND OTHER GUARANTEED PARTIES WITH RESPECT TO
THIS GUARANTY OR ANY DOCUMENT RELATED HERETO. EACH GUARANTOR HEREBY IRREVOCABLY DESIGNATES EACH OF
__________________, AND _______________________, AS THE DESIGNEE, APPOINTEE AND AGENT OF SUCH
GUARANTOR TO RECEIVE, FOR AND ON BEHALF OF SUCH GUARANTOR, SERVICE OF PROCESS IN SUCH JURISDICTION
IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY DOCUMENT RELATED HERETO AND
SUCH SERVICE SHALL BE DEEMED COMPLETED 30 DAYS AFTER MAILING THEREOF TO SAID AGENT. IT IS
UNDERSTOOD THAT A COPY OF SUCH PROCESS SERVED ON SUCH AGENT WILL BE PROMPTLY FORWARDED BY MAIL TO
THE RESPECTIVE GUARANTOR AT ITS ADDRESS SET FORTH HEREIN, BUT THE FAILURE OF SUCH GUARANTOR TO
RECEIVE SUCH COPY SHALL NOT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, AFFECT IN ANY WAY THE
SERVICE OF SUCH PROCESS. IF FOR ANY REASON SERVICE OF PROCESS CANNOT PROMPTLY BE MADE ON EITHER
SUCH LOCAL AGENT, EACH GUARANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF
THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY
REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE COMPANY AT ITS SAID ADDRESS, SUCH SERVICE TO
BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION
OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS IN RESPECT OF THIS GUARANTY OR ANY DOCUMENT RELATED
THERETO. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT TO SERVE PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY
GUARANTOR IN ANY OTHER JURISDICTION.

          (c) TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ALL
RIGHT OF TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN CONNECTION
WITH THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT OR ANY MATTER ARISING IN CONNECTION HEREUNDER OR
THEREUNDER.

          (d) EACH OF THE GUARANTORS AND THE GUARANTEED PARTIES IRREVOCABLY CONSENTS TO SERVICE OF
PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 10.7 OF THE CREDIT AGREEMENT. NOTHING IN
THIS GUARANTY WILL AFFECT THE RIGHT OF ANY SUCH PARTY TO SERVE PROCESS IN ANY MANNER PERMITTED BY
APPLICABLE LAW.

-6-

 

          (e) EACH OF THE GUARANTORS AND THE GUARANTEED PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVES, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THIS SECTION 11 OR OTHERWISE RELATING TO THE
CREDIT DOCUMENTS ANY PUNITIVE DAMAGES.

          SECTION 12. Reserved.

          SECTION 13. Judgment Currency. Each Guarantor’s obligation hereunder to make payments
in the Obligation Currency shall not be discharged or satisfied by any tender or recovery pursuant
to any judgment expressed in or converted into any currency other than the Obligation Currency,
except to the extent that such tender or recovery results in the effective receipt by the
Guaranteed Parties of the full amount of the Obligation Currency expressed to be payable under this
Guaranty or the Credit Agreement. If for the purpose of obtaining or enforcing judgment against
any Guarantor in any court or in any jurisdiction, it becomes necessary to convert into or from any
currency other than the Obligation Currency (such other currency being hereinafter referred to as
the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made in
accordance with Section 10.18 of the Credit Agreement.

          SECTION 14. Automatic Acceleration in Certain Events. Upon the occurrence of an Event
of Default specified in Section 7.1(f) or (g) of the Credit Agreement, all Guaranteed Obligations
shall automatically become immediately due and payable by the Guarantors, without notice or other
action on the part of the Administrative Agent or other Guaranteed Parties, and regardless of
whether payment of the Guaranteed Obligations by the Company has then been accelerated. In
addition, if any event of the types described in Section 7.1(f) or (g) of the Credit Agreement
should occur with respect to any Guarantor that is a Significant Subsidiary, then the Guaranteed
Obligations shall automatically become immediately due and payable by such Guarantor, without
notice or other action on the part of the Administrative Agent or other Guaranteed Parties, and
regardless of whether payment of the Guaranteed Obligations by the Company has then been
accelerated.

          SECTION 15. Maximum Obligations. (a) It is the intent of each Guarantor and the
Guaranteed Parties that each Guarantor’s maximum obligations hereunder shall not be in excess of:

               (i) in a case or proceeding commenced by or against such Guarantor under the Bankruptcy
Code on or within one year from the date on which any of the Guaranteed Obligations are
incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or
any other obligations of such Guarantor to the Guaranteed Parties) to be avoidable or
unenforceable against such Guarantor under (A) Section 548 of the Bankruptcy Code or (B) any
state fraudulent transfer or fraudulent conveyance act or statute applied in such case or
proceeding by virtue of Section 544 of the Bankruptcy Code; or

-7-

 

               (ii) in a case or proceeding commenced by or against such Guarantor under the
Bankruptcy Code subsequent to one year from the date on which any of the Guaranteed
Obligations are incurred, the maximum amount which would not otherwise cause the Guaranteed
Obligations (or any other obligations of such Guarantor to the Guaranteed Parties) to be
avoidable or unenforceable against such Guarantor under any state fraudulent transfer or
fraudulent conveyance act or statute applied in any such case or proceeding by virtue of
Section 544 of the Bankruptcy Code; or

               (iii) in a case or proceeding commenced by or against such Guarantor under any law,
statute or regulation other than the Bankruptcy Code (including, without limitation, any
other bankruptcy, reorganization, arrangement, moratorium, readjustment of debt,
dissolution, liquidation or similar debtor relief laws), the maximum amount which would not
otherwise cause the Guaranteed Obligations (or any other obligations of such Guarantor to
the Guaranteed Parties) to be avoidable or unenforceable against such Guarantor under such
law, statute or regulation including, without limitation, any state fraudulent transfer or
fraudulent conveyance act or statute applied in any such case or proceeding.

(The substantive laws under which the possible avoidance or unenforceability of the Guaranteed
Obligations (or any other obligations of such Guarantor to the Guaranteed Parties) shall be
determined in any such case or proceeding shall hereinafter be referred to as the “Avoidance
Provisions”).

          (b) To the end set forth in Section 15(a), but only to the extent that the Guaranteed
Obligations would otherwise be subject to avoidance under the Avoidance Provisions if such
Guarantor is not deemed to have received valuable consideration, fair value or reasonably
equivalent value for the Guaranteed Obligations, or if the Guaranteed Obligations would
render such Guarantor insolvent, or leave such Guarantor with an unreasonably small capital
to conduct its business, or cause such Guarantor to have incurred debts (or to have intended
to have incurred debts) beyond its ability to pay such debts as they mature, in each case as
of the time any of the Guaranteed Obligations are deemed to have been incurred under the
Avoidance Provisions and after giving effect to rights of contribution, indemnity and
subrogation as among Guarantors and the Company, the maximum Guaranteed Obligations for
which such Guarantor shall be liable hereunder shall be reduced to that amount which, after
giving effect thereto, would not cause the Guaranteed Obligations (or any other obligations
of such Guarantor to the Guaranteed Parties), as so reduced, to be subject to avoidance
under the Avoidance Provisions. This Section 15(b) is intended solely to preserve the
rights of the Guaranteed Parties hereunder to the maximum extent that would not cause the
Guaranteed Obligations of any Guarantor to be subject to avoidance under the Avoidance
Provisions, and neither such Guarantor nor any other Person shall have any right or claim
under this Section 15 as against the Guaranteed Parties that would not otherwise be
available to such Person under the Avoidance Provisions.

          SECTION 16. Indemnity, Contribution, and Subrogation.

-8-

 

          (a) In addition to all such rights of indemnity and subrogation as each Guarantor may have
under applicable law (but subject to Section 4 hereof), the Company agrees that (i) in the event a
payment shall be made on behalf of the Company by any Guarantor hereunder, the Company shall
indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated
to the rights of the person to whom such payment shall have been made to the extent of such
payment, and (ii) in the event any assets of any Guarantor shall be sold to satisfy a claim of any
Guaranteed Party hereunder, the Company shall indemnify such Guarantor in an amount equal to the
greater of the book value or the fair market value of the assets so sold.

          (b) Each Guarantor (a “Contributing Guarantor”) agrees (subject to Section 4 hereof), that, in
the event a payment shall be made by any other Guarantor hereunder, or assets of any other
Guarantor shall be sold to satisfy a claim of any Guaranteed Party hereunder, and such other
Guarantor (the “Claiming Guarantor”) shall not have been fully indemnified by the Company as
provided in paragraph (a) above, each Contributing Guarantor shall indemnify each Claiming
Guarantor in an amount equal to the amount of such payment or the greater of the book value or the
fair market value of such assets, as the case may be, in each case multiplied by a fraction of
which the numerator shall be the net worth of such Contributing Guarantor on the date hereof and
the denominator shall be the aggregate net worth of the Company and all of the Guarantors on the
date hereof (or, in the case of any Guarantor becoming a party hereto pursuant to Section 22, the
date of the Supplement hereto executed and delivered by such Guarantor). Any Contributing
Guarantor making any payment to a Claiming Guarantor pursuant to this paragraph (b) shall be
subrogated to the rights of such Claiming Guarantor under paragraph (a) above to the extent of such
payment. As used herein, the term “net worth” shall mean, as at any date of determination, the
consolidated shareholders’ equity of the Company and the Guarantors, as determined in each case on
a consolidated basis in accordance with GAAP.

          SECTION 17. Information. Each Guarantor assumes all responsibility for being and
keeping itself informed of the Company’s financial condition and assets, and of all other
circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature,
scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that
none of the Guaranteed Parties will have any duty to advise any of the Guarantors of information
known to it or any of them regarding such circumstances or risks.

          SECTION 18. Representations and Warranties. Each Guarantor represents and warrants as
to itself that all representations and warranties relating to it contained in Article 5 of the
Credit Agreement are true and correct.

          SECTION 19. Survival of Agreement. All agreements, representations and warranties
made herein shall survive the execution and delivery of this Guaranty, the Credit Agreement, the
making of the Loans, and the execution and delivery of the Notes and the other Credit Documents and
the issuance of Letters of Credit.

          SECTION 20. Counterparts. This Guaranty and any amendments, waivers, consents or
supplements may be executed in any number of counterparts and by

-9-

 

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.

          SECTION 21. Currency of Payment. All payments to be made by each Guarantor hereunder
shall be made in the applicable currency as provided in Section 10.18 of the Credit Agreement and,
in the case of any required conversion of any currency, shall be determined, and the related
amounts calculated, in the manner provided in Section 10.18 of the Credit Agreement.

          SECTION 22. Additional Guarantors. Upon execution and delivery by any Subsidiary of
the Company of an instrument in the form of Annex 1, such Subsidiary shall become a
Guarantor hereunder with the same force and effect as if originally named a Guarantor herein (each
an “Additional Guarantor”). The execution and delivery of any such instrument shall not require
the consent of any Guarantor hereunder. The rights and obligations of each Guarantor hereunder
shall remain in full force and effect notwithstanding the addition of any Additional Guarantor as a
party to this Guaranty.

          SECTION 23. Termination of Guaranty. In addition to termination upon payment in full
of all of the Guaranteed Obligations (subject to the last sentence of Section 2 hereof), all
obligations of each Guarantor to the Guaranteed Parties hereunder shall terminate upon the delivery
by the Company to the Administrative Agent of a certificate stating that (i) the aggregate
principal amount of Indebtedness of all Subsidiaries outstanding pursuant to Section 6.11(j) and
(k) of the Credit Agreement is equal to or less than the Subsidiary Debt Basket Amount, and (ii) no
Default or Event of Default has occurred and is continuing. Upon compliance with the foregoing,
the Administrative Agent and the Lender shall provide written confirmation of such termination as
may be reasonably requested by such Guarantor.

shares of Common Stock held by VAC;

     C. WHEREAS, the Company, VAC, Credit Suisse Securities (USA) LLC (“Credit Suisse”) and
Goldman, Sachs & Co. (collectively with Credit Suisse, the “Underwriters”) intend to enter into an
agreement pursuant to which VAC will sell up to an aggregate of 8,000,000 shares of Common Stock

1,200,000 additional shares of Common Stock (the “Optional Shares” and, together with the Firm
Shares, the “Underwritten Shares”), to the Underwriters (the “Underwriting Agreement”);

     D. WHEREAS, in addition to the Underwritten Shares to be sold to the Underwriters pursuant to
