CREDIT AGREEMENT

CREDIT AGREEMENT (the “Agreement”) dated as of October 13, 2010, among HEALTHCARE
TRUST OF AMERICA HOLDINGS, LP, a Delaware limited partnership, HEALTHCARE TRUST OF AMERICA, INC., a
Maryland corporation, the LENDERS party hereto, and JPMORGAN CHASE BANK, N.A., as Administrative
Agent.

The parties hereto agree as follows:

ARTICLE I.

DEFINITIONS

SECTION 1.1. Defined Terms. As used in this Agreement, the following terms have the
meanings specified below:

“ABR”, when used in reference to any Loan or Borrowing, refers to whether such Loan,
or the Loans comprising such Borrowing, are bearing interest at a rate determined by reference to
the Alternate Base Rate.

“Adjusted LIBO Rate” means, with respect to any Eurodollar Borrowing for any Interest
Period, an interest rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to
(a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate.

“Adjusted NOI” means for any fiscal period, the NOI (or proportionate share of NOI
from a Property owned by an Unconsolidated Affiliate) from a Property and adjusted to (a) remove
the effect of recognizing rental income on a straight-line basis over the applicable lease term and
(b) deduct Property Management Fees. As used herein, “Property Management Fees” means,
with respect to each Property (other than a Property for which the Borrower or Subsidiary has a
triple-net lease in effect) for any period, an amount equal to the greater of (a) actual management
fees for such Property and (b) an assumed amount equal to three percent (3%) of the aggregate rent
due and payable under leases with tenants at such Property.

“Administrative Agent” means JPMorgan Chase Bank, N.A., in its capacity as
administrative agent for the Lenders hereunder.

“Administrative Questionnaire” means an Administrative Questionnaire in a form
supplied by the Administrative Agent.

“Affiliate” means, with respect to a specified Person, another Person that directly,
or indirectly through one or more intermediaries, Controls or is Controlled by or is under common
Control with the Person specified.

“Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of
(a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such
day plus 1/2 of 1% and (c) the Adjusted LIBO Rate for a one month Interest Period on such day (or if
such day is not a Business Day, the immediately preceding Business Day) plus 1%, provided
that, for the avoidance of doubt, the Adjusted LIBO Rate for any day shall be based on the rate
appearing on the Reuters BBA Libor Rates Page 3750 (or on any successor or substitute page of such
page) at approximately 11:00 a.m. London time on such day. Any change in the Alternate Base Rate
due to a change in the Prime Rate, the Federal Funds Effective Rate or the Adjusted LIBO Rate shall
be effective from and including the effective date of such change in the Prime Rate, the Federal
Funds Effective Rate or the Adjusted LIBO Rate, respectively.

“Applicable Credit Rating” means a rating assigned to the Borrower’s Index Debt of at
least BBB- or higher by S&P or Baa3 or higher by Moody’s.

“Applicable Percentage” means, with respect to any Lender, the percentage of the total
Commitments represented by such Lender’s Commitment; provided that in the case of Section
2.20 when a Defaulting Lender shall exist, “Applicable Percentage” shall mean the percentage of the
total Commitments (disregarding any Defaulting Lender’s Commitment) represented by such Lender’s
Commitment. If the Commitments have terminated or expired, the Applicable Percentages shall be
determined based upon the Commitments most recently in effect, giving effect to any assignments and
to any Lender’s status as a Defaulting Lender at the time of determination.

“Applicable Rate” means, for any day, with respect to any ABR Loan or Eurodollar
Revolving Loan, or with respect to the facility fees payable hereunder, as the case may be, the
applicable rate per annum determined as set forth below:

(i) if the Borrower has not obtained two Applicable Credit Ratings, the “Base Rate -
Applicable Rate” or the “LIBOR Rate — Applicable Rate” as the case may be, shall be determined by
the range into which the Total Leverage Ratio of the Borrower falls in the table below:

	 	 	 	 	 	 	 	 	 	 	 
	RATIO LEVEL	 	TOTAL LEVERAGE RATIO	 	BASE RATE - APPLICABLE	 	LIBOR RATE -
	 	 	 	 	RATE	 	APPLICABLE
	 	 	 	 	 	 	 	 	RATE
	Level I

	 	< 35%
	 	 	1.60	%	 	 	2.60	%
	 

	 	 
	 	 	 	 	 	 	 	 
	Level II

	 	> 3 5% AND < 45%
	 	 	2.00	%	 	 	3.00	%
	 

	 	 
	 	 	 	 	 	 	 	 
	Level III

	 	> 45% AND < 55%
	 	 	2.50	%	 	 	3.50	%
	 

	 	 
	 	 	 	 	 	 	 	 

For purposes of this clause (i), any increase or decrease in the Applicable Rate resulting
from a change in the Total Leverage Ratio shall become effective as of the first Business Day
immediately following the date a compliance certificate is delivered in accordance with Section
5.1(c); provided, however, that if such compliance certificate is not delivered
when due in accordance with Section 5.1(c), then the Applicable Rate shall be the percentage that
would apply to the Level III Ratio and it shall apply as of the first Business Day after the date
on which such compliance certificate was required to have been delivered; or

(ii) if the Borrower obtains two Applicable Credit Ratings, the “Base Rate — Applicable Rate”,
the “LIBOR Rate — Applicable Rate” or the “Facility Fee Rate”, as the case may be, shall be
determined solely by the Ratings of the Borrower in the table below:

	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 
	RATINGS LEVEL	 	MOODY’S/	 	BASE RATE -	 	LIBOR RATE -	 	FACILITY FEE RATE

	 	 	1.15	%	 	 	2.15	%	 	 	0.45	%
	 
	 	 

	 	 	 	 	 	 	 	 	 	 	 	 
	Level III Rating
	 	Baa3/BBB-

	 	 	1.50	%	 	 	2.50	%	 	 	0.50	%
	 
	 	 

	 	 	 	 	 	 	 	 	 	 	 	 
	Level IV Rating
	 	Below Baa3/BBB-

	 	 	1.95	%	 	 	2.95	%	 	 	0.55	%
	 
	 	 

	 	 	 	 	 	 	 	 	 	 	 	 

For purposes of this clause (ii), (A) if the Borrower has two Ratings and the Ratings of the
Rating Agencies do not match, then the higher of two Applicable Credit Ratings shall determine
pricing; provided, however, that if the two Applicable Credit Ratings are two or
more gradations apart, then the rating that is the mid-point between the two differing Applicable
Credit Ratings (rounding down, if such mid-point falls between two ratings) shall determine pricing
and (B) if the Applicable Credit Ratings established or deemed to have been established by the
Rating Agencies for the Index Debt shall be changed (other than as a result of change in the rating
system of any such Rating Agency), such change shall be effective as of the date on which it is
first announced by the applicable Rating Agency, irrespective of when notice of such change shall
have been furnished by the Borrower to the Administrative Agent and the Lenders. Each change in
the Applicable Rate under this clause (ii) shall apply during the period commencing on the
effective date of such change and ending on the date immediately preceding the effective date of
the next such change. If the rating system of a Rating Agency shall change, or if any Rating
Agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the
Lenders shall negotiate in good faith to amend this definition to reflect such changed rating
system or the unavailability of ratings from such Rating Agency, and pending the effectiveness of
any such amendment, the Applicable Credit Rating assigned by such Rating Agency shall be deemed to
be the rating most recently in effect prior to such change or cessation and the Applicable Rate
shall be determined by reference to such rating.

The Applicable Credit Rating in effect on any date for the purposes of this definition is that
in effect at the close of business on such date. If at any time the Borrower does not have both a
Moody’s Rating and an S&P Rating, then the Applicable Rate shall be determined by reference to the
Total Leverage Ratio in accordance with clause (i).

Any adjustment in the Applicable Rate shall be applicable to all existing Loans.

The Borrower understands that the Applicable Rate shall be determined and/or adjusted from
time-to-time based upon certain financial ratios and/or other information to be provided or
certified to the Administrative Agent and the Lenders by the Borrower (the “Borrower Information”).
If it is subsequently determined that any such Borrower Information was incorrect (for any reason)
at the time it was delivered to the Administrative Agent and the Lenders, and if the Applicable
Rate calculated for any period was higher or lower than it should have been had the correct
information been timely provided, then, such interest rate for such period shall be automatically
recalculated using the correct Borrower Information. The Agent shall promptly notify the Borrower
and the Lenders in writing of any additional interest due or the amount of any overpayment of
interest because of such recalculation, and (x) in the case of underpayment, the Borrower shall pay
such additional interest due to the Lenders within 5 Business Days of receipt of such written
notice and (y) in the case of overpayment, the Borrower shall receive a credit against its next
interest payment for the amount of such overpayment.

Any recalculation of interest required by this provision shall survive termination of this
Agreement and this provision shall not in any way limit any of the Administrative Agent’s and the
Lenders’ other rights and remedies under the Loan Documents.

“Approved Fund” has the meaning assigned to such term in Section 9.4.

“Assignment and Assumption” means an assignment and assumption entered into by a
Lender and an assignee (with the consent of any party whose consent is required by Section 9.4),
and accepted by the Administrative Agent, in the form of Exhibit A or any other form approved by
the Administrative Agent.

“Available Commitment” means, as to any Lender at any time, an amount equal to the
excess, if any, of (a) such Lender’s Commitment then in effect minus (b) such Lender’s
Revolving Credit Exposure then outstanding; provided, that in calculating any Lender’s
Revolving Credit Exposure for the purpose of determining such Lender’s Available Commitment
pursuant to Section 2.12(a), the aggregate principal amount of Swingline Loans then outstanding
shall be deemed to be zero.

“Availability Period” means the period from and including the Effective Date to but
excluding the earlier of the Maturity Date and the date of termination of the Commitments.

“Bankruptcy Event” means, with respect to any Person, such Person becomes the subject
of a bankruptcy or insolvency proceeding, or has had a receiver, conservator, trustee,
administrator, custodian, assignee for the benefit of creditors or similar Person charged with the
reorganization or liquidation of its business appointed for it, or, in the good faith determination
of the Administrative Agent, has taken any action in furtherance of, or indicating its consent to,
approval of, or acquiescence in, any such proceeding or appointment, provided that a Bankruptcy
Event shall not result solely by virtue of any ownership interest, or the acquisition of any
ownership interest, in such Person by a Governmental Authority or instrumentality thereof,
provided, further, that such ownership interest does not result in or provide such Person with
immunity from the jurisdiction of courts within the United States or from the enforcement of
judgments or writs of attachment on its assets or permit such Person (or such Governmental
Authority or instrumentality) to reject, repudiate, disavow or disaffirm any contracts or
agreements made by such Person.

the London interbank market.

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing;

(iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be
applicable thereto, which shall be a period contemplated by the definition of the
term “Interest Period”; and

(v) the location and number of the Borrower’s account to which funds are to be
disbursed, which shall comply with the requirements of Section 2.7.

If no election as to the Type of Revolving Borrowing is specified, then the requested Revolving
Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any
requested Eurodollar Revolving Borrowing, then the Borrower shall be deemed to have selected an
Interest Period of one month’s duration. Promptly following receipt of a Borrowing Request in
accordance with this Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

SECTION 2.4. Incremental Commitments. (a) The Borrower may, by written notice to the
Administrative Agent on up to two (2) occasions during the period from the Closing Date to the nine
(9) month anniversary of the Closing Date, request incremental Commitments in an amount not to
exceed the aggregate amount of $200,000,000 from one or more additional Lenders (which may include
any existing Lender) willing to provide such incremental Commitments in their own discretion;
provided, that each incremental Lender shall be subject to the approval of the Administrative Agent
(which approval shall not be unreasonably withheld) unless such incremental Lender is a Lender, an
Affiliate of a Lender or an Approved Fund. Such notice shall set forth (i) the amount of the
incremental Commitments being requested, (ii) the aggregate amount of all incremental Commitments,
which when taken together with all other incremental Commitments, shall not exceed $200,000,000 in
the aggregate (the “Incremental Limit”), and (iii) the date on which such incremental
Commitments are requested to become effective (the “Increased Amount Date”). The
Administrative Agent and/or its Affiliates shall use commercially reasonable efforts, with the
assistance of the Borrower, to arrange a syndicate of Lenders willing to hold the requested
incremental Commitments.

(b) The Borrower and each incremental Lender shall execute and deliver to the
Administrative Agent such documentation as the Administrative Agent shall reasonably specify
to evidence the incremental Commitment of such incremental Lender. Each such documentation
shall specify the terms of the applicable incremental Commitments; provided, that from and
after the effectiveness of each amendment or other documentation, the associated incremental
Commitments shall thereafter be Commitments with the same terms as the Commitments
(including as to pricing and maturity). Each of the parties hereto hereby agrees that, upon
the effectiveness of any such documentation, this Agreement shall be amended to the extent
(but only to the extent) necessary to reflect the existence and terms of the incremental
Commitments evidenced thereby (including adjusting the Applicable Percentages), and new
Notes shall be issued and the Borrower shall make such borrowings and repayments as shall be
necessary to effect the reallocation of the Commitments, in each case without the consent of
the Lenders other than those Lenders with incremental Commitments. The fees payable by the
Borrower upon any such incremental Commitments shall be agreed upon by the Administrative
Agent, the Lenders with incremental Commitments and the Borrower at the time of such
increase. Notwithstanding the forgoing, nothing in this Section 2.4 shall constitute or be
deemed to constitute an agreement by any Lender to increase its Commitments hereunder.

(c) Notwithstanding the foregoing, no incremental Commitment shall become effective
under this Section 2.4 unless (i) on the date of such effectiveness, the conditions set
forth in Section 4.2 shall be satisfied and the Administrative Agent shall have received a
certificate to that effect dated such date and executed by a Financial Officer of the
Borrower, (ii) the Administrative Agent shall have received customary legal opinions, board
resolutions and other customary closing certificates and documentation as required by the
relevant amendment or other documentation and, to the extent required by the Administrative
Agent, consistent with those delivered on the Closing Date under Section 4.1 and such
additional customary documents and filings as the Administrative Agent may reasonably
require, and (iii) the Borrower shall be in pro forma compliance with the covenants set
forth in Section 6.13 after giving effect to such incremental Commitments, the Loans to be
made thereunder and the application of the proceeds therefrom as if made and applied on such
date.

(d) Each of the parties hereto hereby agrees that the Administrative Agent may take any
and all action as may be reasonably necessary to ensure that all Loans in respect of
incremental Commitments, when originally made, are included in each Borrowing of outstanding
Loans on a pro rata basis. The Borrower agrees that Section 2.16 shall apply to any
conversion of Eurodollar Loans to ABR Loans reasonably required by the Lenders to effect the
foregoing.

SECTION 2.5. Swingline Loans. (a) Subject to the terms and conditions set forth
herein, the Swingline Lender agrees to make Swingline Loans to the Borrower from time to time
during the Availability Period, in an aggregate principal amount at any time outstanding that will
not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding
$15,000,000 or (ii) the sum of the total Revolving Credit Exposures exceeding the total
Commitments; 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, the Borrower may borrow, prepay and reborrow Swingline
Loans.

(b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of
such request by telephone (confirmed by telecopy), not later than 1:00 p.m., New York City
time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and
shall specify the requested date (which shall be a Business Day) and amount of the requested
Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any
such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan
available to the Borrower by means of a credit to the general deposit account of the
Borrower with the Swingline Lender (or, in the case of a Swingline Loan made to finance the
reimbursement of an LC Disbursement as provided in Section 2.6(e), by remittance to the
Issuing Bank) by 3:00 p.m., New York City time, on the requested date of such Swingline
Loan.

(c) The Swingline Lender may by written notice given to the Administrative Agent not
later than 10:00 a.m., New York City time, on any Business Day require the Lenders to
acquire participations on such Business Day in all or a portion of the Swingline Loans
outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which
Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent
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 Applicable
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 reduction or termination of the
Commitments, 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 2.7 with respect to Loans made by such Lender (and Section 2.7 shall
apply, mutatis mutandis, to the payment obligations of the Lenders), and the
Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by
it from the Lenders. The Administrative Agent shall notify the Borrower of any
participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter
payments in respect of such Swingline Loan shall be made to the Administrative Agent and not
to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or
other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the
Swingline Lender of the proceeds of a sale of participations therein shall be promptly
remitted to the Administrative Agent; any such amounts received by the Administrative Agent
shall be promptly remitted by the Administrative Agent to the Lenders that shall have made
their payments pursuant to this paragraph and to the Swingline Lender, as their interests
may appear; provided that any such payment so remitted shall be repaid to the Swingline
Lender or to the Administrative Agent, as applicable, if and to the extent such payment is
required to be refunded to the Borrower for any reason. The purchase of participations in a
Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any repayment
obligation with respect to such Swingline Loan.

SECTION 2.6. Letters of Credit. (a) General. Subject to the terms and
conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own
account, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any
time and from time to time during the Availability Period. In the event of any inconsistency
between the terms and conditions of this Agreement and the terms and conditions of any form of
letter of credit application or other agreement submitted by the Borrower to, or entered into by
the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of
this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To
request the issuance of a Letter of Credit (or the amendment, renewal or extension of an
outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by
electronic communication, if arrangements for doing so have been approved by the Issuing
Bank) to the Issuing Bank and the Administrative Agent (reasonably in advance of the
requested date of issuance, amendment, renewal or extension) a notice requesting the
issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed
or extended, and specifying the date of issuance, amendment, renewal or extension (which
shall be a Business Day), the date on which such Letter of Credit is to expire (which shall
comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name
and address of the beneficiary thereof and such other information as shall be necessary to
prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank,
the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard
form in connection with any request for a Letter of Credit. A Letter of Credit shall be
issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or
extension of each Letter of Credit the Borrower shall be deemed to represent and warrant
that), after giving effect to such issuance, amendment, renewal or extension (i) the LC
Exposure shall not exceed 10% of the total Commitments and (ii) the sum of the total
Revolving Credit Exposures shall not exceed the total Commitments.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the
close of business on the earlier of (i) the date one (1) year after the date of the issuance
of such Letter of Credit (or, in the case of any renewal or extension thereof, one year
after such renewal or extension) and (ii) the date that is five Business Days prior to the
Maturity Date.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to
a Letter of Credit increasing the amount thereof) and without any further action on the part
of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each
Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal
to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under
such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender
hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the
account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement
made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in
paragraph (e) of this Section, or of any reimbursement payment required to be refunded to
the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to
acquire participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance whatsoever,
including any amendment, renewal or extension of any Letter of Credit or the occurrence and
continuance of a Default or reduction or termination of the Commitments, and that each such
payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in
respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying
to the Administrative Agent an amount equal to such LC Disbursement not later than 1:00
p.m., New York City time, on the date that such LC Disbursement is made, if the Borrower
shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time,
on such date, or, if such notice has not been received by the Borrower prior to such time on
such date, then not later than 1:00 p.m., New York City time, on (i) the Business Day that
the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York
City time, on the day of receipt, or (ii) the Business Day immediately following the day
that the Borrower receives such notice, if such notice is not received prior to such time on
the day of receipt; provided that the Borrower may, subject to the conditions to
borrowing set forth herein, request in accordance with Section 2.3 or 2.5 that such payment
be financed with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and,
to the extent so financed, the Borrower’s obligation to make such payment shall be
discharged and replaced by the resulting ABR Revolving Borrowing or Swingline Loan. If the
Borrower fails to make such payment when due, the Administrative Agent shall notify each
Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect
thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such
notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the
payment then due from the Borrower, in the same manner as provided in Section 2.7 with
respect to Loans made by such Lender (and Section 2.7 shall apply, mutatis
mutandis, to the payment obligations of the Lenders), and the Administrative Agent
shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders.
Promptly following receipt by the Administrative Agent of any payment from the Borrower
pursuant to this paragraph, the Administrative Agent shall distribute such payment to the
Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to
reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may
appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing
Bank for any LC Disbursement (other than the funding of ABR Revolving Loans or a Swingline
Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrower
of its obligation to reimburse such LC Disbursement.

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

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

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement,
then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC
Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and
including the date such LC Disbursement is made to but excluding the date that the Borrower
reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving
Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when
due pursuant to paragraph (e) of this Section, then Section 2.13(d) shall apply. Interest
accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that
interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of
this Section to reimburse the Issuing Bank shall be for the account of such Lender to the
extent of such payment.

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any
time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing
Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of
any such replacement of the Issuing Bank. At the time any such replacement shall become
effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced
Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such
replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the
Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter
and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such
successor or to any previous Issuing Bank, or to such successor and all previous Issuing
Banks, as the context shall require. After the replacement of an Issuing Bank hereunder,
the replaced Issuing Bank shall remain a party hereto and shall continue to have all the
rights and obligations of an Issuing Bank under this Agreement with respect to Letters of
Credit issued by it prior to such replacement, but shall not be required to issue additional
Letters of Credit.

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

SECTION 2.7. Funding of Borrowings. (a) Each Lender shall make each Loan to be made
by it hereunder on the proposed date thereof by wire transfer of immediately available funds by
12:00 noon, New York City time, to the account of the Administrative Agent most recently designated
by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be
made as provided in Section 2.5. The Administrative Agent will make such Loans available to the
Borrower by promptly crediting the amounts so received, in like funds, to an account of the
Borrower maintained with the Administrative Agent in New York City and designated by the Borrower
in the applicable Borrowing Request; provided that ABR Revolving Loans made to finance the
reimbursement of an LC Disbursement as provided in Section 2.6(e) shall be remitted by the
Administrative Agent to the Issuing Bank.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to
the proposed date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may
assume that such Lender has made such share available on such date in accordance with
paragraph (a) of this Section and may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. In such event, if a Lender has not in fact made its
share of the applicable Borrowing available to the Administrative Agent, then the applicable
Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on
demand such corresponding amount with interest thereon, for each day from and including the
date such amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal
Funds Effective Rate and a rate determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation or (ii) in the case of the Borrower, the
interest rate applicable to ABR Loans. If such Lender pays such amount to the
Administrative Agent, then such amount shall constitute such Lender’s Loan included in such
Borrowing.

SECTION 2.8. Interest Elections. (a) Each Revolving Borrowing initially shall be of
the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Revolving
Borrowing, shall have an initial Interest Period as specified in such Borrowing Request.
Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue
such Borrowing and, in the case of a Eurodollar Revolving Borrowing, may elect Interest Periods
therefor, all as provided in this Section. The Borrower may elect different options with respect
to different portions of the affected Borrowing, in which case each such portion shall be allocated
ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising
each such portion shall be considered a separate Borrowing. This Section shall not apply to
Swingline Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, the Borrower shall notify the
Administrative Agent of such election by telephone by the time that a Borrowing Request
would be required under Section 2.3 if the Borrower were requesting a Revolving Borrowing of
the Type resulting from such election to be made on the effective date of such election.
Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed
promptly by hand delivery or telecopy to the Administrative Agent of a written Interest
Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.2:

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

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

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

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

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

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

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

SECTION 2.9. Termination and Reduction of Commitments. (a) Unless previously
terminated, the Commitments shall terminate on the Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the
Commitments; provided that (i) each reduction of the Commitments shall be in an
amount that is an integral multiple of $1,000,000 and not less than $5,000,000, or the
remaining balance of the Commitments, if less, and (ii) the Borrower shall not terminate or
reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in
accordance with Section 2.11, the sum of the Revolving Credit Exposures would exceed the
total Commitments.

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

SECTION 2.10. Repayment of Loans; Evidence of Debt. (a) The Borrower hereby
unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the
then unpaid principal amount of each Revolving Loan on the Maturity Date and (ii) to the Swingline
Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Maturity Date
and the first date after such Swingline Loan is made that is the 15th or last day of a calendar
month and is at least two Business Days after such Swingline Loan is made; provided that on
each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then
outstanding.

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

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

(d) The entries made in the accounts maintained pursuant to 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 Borrower to repay the Loans in accordance with the terms of
this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In
such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note
payable to the order of such Lender (or, if requested by such Lender, to such Lender and its
registered assigns) and in a form approved by the Administrative Agent. Thereafter, the
Loans evidenced by such promissory note and interest thereon shall at all times (including
after assignment pursuant to Section 9.4) be represented by one or more promissory notes in
such form payable to the order of the payee named therein (or, if such promissory note is a
registered note, to such payee and its registered assigns).

SECTION 2.11. Prepayment of Loans. (a) The Borrower shall have the right at any time
and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in
accordance with paragraph (b) of this Section.

(b) The Borrower shall notify the Administrative Agent (and, in the case of prepayment
of a Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any
prepayment hereunder (i) in the case of prepayment of a Eurodollar Revolving Borrowing, not
later than 1:00 p.m., New York City time, three Business Days before the date of prepayment,
(ii) in the case of prepayment of an ABR Revolving Borrowing, not later than 1:00 p.m., New
York City time, one Business Day before the date of prepayment or (iii) in the case of
prepayment of a Swingline Loan, not later than 1:00 p.m., New York City time, on the date of
prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and
the principal amount of each Borrowing or portion thereof to be prepaid; provided
that, if a notice of prepayment is given in connection with a conditional notice of
termination of the Commitments as contemplated by Section 2.9, then such notice of
prepayment may be revoked if such notice of termination is revoked in accordance with
Section 2.9. Promptly following receipt of any such notice relating to a Revolving
Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each
partial prepayment of any Revolving Borrowing shall be in an amount that would be permitted
in the case of an advance of a Revolving Borrowing of the same Type as provided in Section
2.2. Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans
included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to
the extent required by Section 2.13.

SECTION 2.12. Fees.

(a) (i) If the Applicable Rate is determined by reference to the Applicable Credit
Ratings, the Borrower agrees to pay to the Administrative Agent for the account of each
Lender a facility fee, which shall accrue at the Facility Fee Rate (as set forth in the
definition of Applicable Rate) on the daily amount of the Commitment of such Lender (whether
used or unused) during the period from and including the date on which the facility fee is
first applicable to but excluding the date on which such Commitment terminates;
provided that, if such Lender continues to have any Revolving Credit Exposure after
its Commitment terminates, then such facility fee shall continue to accrue on the daily
amount of such Lender’s Revolving Credit 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. Accrued facility fees shall be payable in arrears on the last
day of March, June, September and December of each year and on the date on which the
Commitments terminate, commencing on the first such date to occur after the date hereof;
provided that any facility fees accruing after the date on which the Commitments
terminate shall be payable on demand. 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).

(ii) If the Applicable Rate is determined by reference to the Leverage Ratio,
the Borrower agrees to pay to the Administrative Agent for the account of each
Lender a commitment fee for the period from and including the date hereof to the
last day of the Availability Period, computed at the Commitment Fee Rate on the
average daily amount of the Available Commitment of such Lender during the period
for which payment is made, payable quarterly in arrears on each last day of each
March, June, September and December of each year end on the date on which the
Commitments terminate, commencing on the first such date to occur after the date
hereof.

(b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each
Lender a participation fee with respect to its participations in Letters of Credit, which
shall accrue at the same Applicable Rate used to determine the interest rate applicable to
Eurodollar Revolving Loans on the average daily amount of such Lender’s LC Exposure
(excluding any portion thereof attributable to unreimbursed LC Disbursements and accrued and
unpaid interest thereon) during the period from and including the Effective Date to but
excluding the later of the date on which such Lender’s Commitment terminates and the date on
which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting
fee, which shall accrue at the rate of 0.20% per annum on the average daily amount of the LC
Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements and
accrued and unpaid interest thereon) during the period from and including the Effective Date
to but excluding the later of the date of termination of the Commitments and the date on
which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with
respect to the issuance, amendment, renewal or extension of any Letter of Credit or
processing of drawings thereunder. Participation fees and fronting fees accrued through and
including the last day of March, June, September and December of each year shall be payable
on the third Business Day following such last day, commencing on the first such date to
occur after the Effective Date; provided that all such fees shall be payable on the
date on which the Commitments terminate and any such fees accruing after the date on which
the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing
Bank pursuant to this paragraph shall be payable within 10 days after demand. All
participation fees and fronting 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).

(c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees
payable in the amounts and at the times separately agreed upon between the Borrower and the
Administrative Agent.

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

SECTION 2.13. Interest. (a) The Loans comprising each ABR Borrowing (including each
Swingline Loan) shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted
LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Notwithstanding the foregoing, if at any time an Event of Default has occurred and
is continuing, all outstanding Loans and other Obligations shall bear interest, after as
well as before judgment, at a rate per annum equal to (i) in the case of principal of any
Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding
paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Loans as provided in paragraph (a) of this Section.

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

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except
that interest computed by reference to the Alternate Base Rate at times when the Alternate
Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days
(or 366 days in a leap year), and in each case shall be payable for the actual number of
days elapsed (including the first day but excluding the last day). The applicable Alternate
Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent,
and such determination shall be conclusive absent manifest error.

SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of any
Interest Period for a Eurodollar Borrowing:

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

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

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

SECTION 2.15. Increased Costs. (a) If any Change in Law shall:

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

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

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

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

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

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand
compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the
Issuing Bank’s right to demand such compensation; provided that the Borrower shall
not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any
increased costs or reductions incurred more than 270 days prior to the date that such Lender
or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving
rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s
intention to claim compensation therefor; provided further that, if the
Change in Law giving rise to such increased costs or reductions is retroactive, then the
270-day period referred to above shall be extended to include the period of retroactive
effect thereof. If such increased costs or reductions are paid by the Borrower and a Lender
subsequently determines in good faith that it has received a refund of such amounts from a
third party that are directly attributable to this Agreement, then such Lender shall
promptly deliver such refund to the Borrower.

SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan other than on the last day of an Interest Period applicable
thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan
other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow,
convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered
pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is
revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan other than on the
last day of the Interest Period applicable thereto as a result of a request by the Borrower
pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for
the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such
loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender
to be the excess, if any, of (i) the amount of interest which would have accrued on the principal
amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been
applicable to such Loan, for the period from the date of such event to the last day of the then
current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for
the period that would have been the Interest Period for such Loan), over (ii) the amount of
interest which would accrue on such principal amount for such period at the interest rate which
such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a
comparable amount and period from other banks in the eurodollar market. A certificate of any
Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this
Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

SECTION 2.17. Taxes. (a) Any and all payments by or on account of any obligation of
the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified
Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (as
the case may be) receives an amount equal to the sum it would have received had no such deductions
been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing
Bank, within 10 days after written demand therefor, for the full amount of any Indemnified
Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as
the case may be, on or with respect to any payment by or on account of any obligation of the
Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest and
reasonable expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the Borrower by a Lender or the Issuing Bank, or by the
Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall
be conclusive absent manifest error.

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

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

(f) If the Administrative Agent or a Lender determines, in its sole discretion, that it
has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the
Borrower or with respect to which the Borrower has paid additional amounts pursuant to this
Section 2.17, it shall pay over such refund to the Borrower (but only to the extent of
indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.17
with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent or such Lender and without interest
(other than any interest paid by the relevant Governmental Authority with respect to such
refund); provided, that the Borrower, upon the request of the Administrative Agent or such
Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest
or other charges imposed by the relevant Governmental Authority) to the Administrative Agent
or such Lender in the event the Administrative Agent or such Lender is required to repay
such refund to such Governmental Authority. This Section shall not be construed to require
the Administrative Agent or any Lender to make available its tax returns (or any other
information relating to its taxes which it deems confidential) to the Borrower or any other
Person.

SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The
Borrower shall make each payment required to be made by it hereunder (whether of principal,
interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16
or 2.17, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in
immediately available funds, without set-off or counterclaim. Any amounts received after such time
on any date may, in the discretion of the Administrative Agent, be deemed to have been received on
the next succeeding Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York,
except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided
herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.3 shall be made
directly to the Persons entitled thereto. The Administrative Agent shall distribute any such
payments received by it for the account of any other Person to the appropriate recipient promptly
following receipt thereof (and the Borrower shall have no liability for the Administrative Agent’s
failure to make such distributions). If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in
the case of any payment accruing interest, interest thereon shall be payable for the period of such
extension. All payments hereunder shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the
Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements,
interest and fees then due hereunder, such funds shall be applied (i) first, towards payment
of interest and fees then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of interest and fees then due to such parties, and (ii) second,
towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

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

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

(e) If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.5(c), 2.6(d) or (e), 2.7(b), 2.18(d) or 9.3(c), then the Administrative Agent may,
in its discretion and notwithstanding any contrary provision hereof, (i) apply any amounts
thereafter received by the Administrative Agent for the account of such Lender for the
benefit of the Administrative Agent, the Swingline Lender or the Issuing Bank to satisfy
such Lender’s obligations to it under such Section until all such unsatisfied obligations
are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral
for, and application to, any future funding obligations of such Lender under any such
Section, in the case of each of clauses (i) and (ii) above, in any order as determined by
the Administrative Agent in its discretion.

SECTION 2.19. Mitigation Obligations; Replacement of Lenders. (a) If any Lender
requests compensation under Section 2.15, or if the Borrower is required to pay any additional
amount to any Lender or any Governmental Authority for the account of any Lender pursuant to
Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office
for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to
another of its offices, branches or affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or
2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed
cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such
designation or assignment.

(b) If any Lender requests compensation under Section 2.15, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the
account of any Lender pursuant to Section 2.17, or if any Lender becomes a Defaulting
Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender
and the Administrative Agent, require such Lender to assign and delegate, without recourse
(in accordance with and subject to the restrictions contained in Section 9.4), all its
interests, rights and obligations under this Agreement to an assignee that shall assume such
obligations (which assignee may be another Lender, if a Lender accepts such assignment);
provided that (i) the Borrower shall have received the prior written consent of the
Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which
consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of
an amount equal to the outstanding principal of its Loans and participations in LC
Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other
amounts payable to it hereunder, from the assignee (to the extent of such outstanding
principal and accrued interest and fees) or the Borrower (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for compensation under
Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will
result in a reduction in such compensation or payments. A Lender shall not be required to
make any such assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such assignment and
delegation cease to apply and such Lender confirms that is it not then aware of any similar
circumstances.

SECTION 2.20. Defaulting Lenders. Notwithstanding any provision of this Agreement to
the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply
for so long as such Lender is a Defaulting Lender:

(a) fees shall cease to accrue on the Commitment of such Defaulting Lender pursuant to
Section 2.12(a)(i) and fees shall cease to accrue on the unfunded portion of the Commitment
of such Defaulting Lender pursuant to Section 2.12(a)(ii), as applicable;

(b) the Commitment and Revolving Credit Exposure of such Defaulting Lender shall not be
included in determining whether the Required Lenders have taken or may take any action
hereunder (including any consent to any amendment, waiver or other modification pursuant to
Section 9.2); provided, that this clause (b) shall not apply to the vote of a Defaulting
Lender in the case of an amendment, waiver or other modification requiring the consent of
such Lender or each Lender affected thereby except (i) such Defaulting Lender’s Commitment
may not be increased or extended without its consent and (ii) the principal amount of, or
interest or fees payable on, Loans or LC Disbursements owing to such Defaulting Lender may
not be reduced or excused or the scheduled date of payment may not be postponed as to such
Defaulting Lender without such Defaulting Lender’s consent; 

(c) if any Swingline Exposure or LC Exposure exists at the time such Lender becomes a
Defaulting Lender then:

(i) all or any part of the Swingline Exposure and LC Exposure of such
Defaulting Lender shall be reallocated among the non-Defaulting Lenders in
accordance with their respective Applicable Percentages but only to the extent the
sum of all non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting
Lender’s Swingline Exposure and LC Exposure does not exceed the total of all
non-Defaulting Lenders’ Commitments;

(ii) if the reallocation described in clause (i) above cannot, or can only
partially, be effected, the Borrower shall within one Business Day following notice
by the Administrative Agent (x) first, prepay such Swingline Exposure and (y)
second, cash collateralize for the benefit of the Issuing Bank only the Borrower’s
obligations corresponding to such Defaulting Lender’s LC Exposure (after giving
effect to any partial reallocation pursuant to clause (i) above) in accordance with
the procedures set forth in Section 2.6(j) for so long as such LC Exposure is
outstanding and the Borrower will be permitted to use proceeds of the Loans for such
purposes;

(iii) if the Borrower cash collateralizes any portion of such Defaulting
Lender’s LC Exposure pursuant to clause (ii) above, the Borrower shall not be
required to pay any fees to such Defaulting Lender pursuant to Section 2.12(b) with
respect to such Defaulting Lender’s LC Exposure during the period such Defaulting
Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant
to clause (i) above, then the fees payable to the Lenders pursuant to Section
2.12(a)(ii) shall be adjusted in accordance with such non-Defaulting Lenders’
Applicable Percentages; and

(v) if all or any portion of such Defaulting Lender’s LC Exposure is neither
reallocated nor cash collateralized pursuant to clause (i) or (ii) above, then,
without prejudice to any rights or remedies of the Issuing Bank or any other Lender
hereunder, all facility fees that otherwise would have been payable to such
Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s
Commitment that was utilized by such LC Exposure) and letter of credit fees payable
under Section 2.12(b) with respect to such Defaulting Lender’s LC Exposure shall be
payable to the Issuing Bank until and to the extent that such LC Exposure is
reallocated and/or cash collateralized; and

(d) so long as such Lender is a Defaulting Lender, the Swingline Lender shall not be
required to fund any Swingline Loan and the Issuing Bank shall not be required to issue,
amend or increase any Letter of Credit, unless it is satisfied that the related exposure and
the Defaulting Lender’s then outstanding LC Exposure will be 100% covered by the Commitments
of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in
accordance with Section 2.20(c), and participating interests in any newly made Swingline
Loan or any newly issued or increased Letter of Credit shall be allocated among
non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and such Defaulting
Lender shall not participate therein).

If (i) a Bankruptcy Event with respect to a Parent of any Lender shall occur following the
date hereof and for so long as such event shall continue or (ii) the Swingline Lender or the
Issuing Bank has a good faith belief that any Lender has defaulted in fulfilling its obligations
under one or more other agreements in which such Lender commits to extend credit, the Swingline
Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be required
to issue, amend or increase any Letter of Credit, unless the Swingline Lender or the Issuing Bank,
as the case may be, shall have entered into arrangements with the Borrower or such Lender,
satisfactory to the Swingline Lender or the Issuing Bank, as the case may be, to defease any risk
to it in respect of such Lender hereunder.

In the event that the Administrative Agent, the Borrower, the Swingline Lender and the Issuing
Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused such
Lender to be a Defaulting Lender, then the Swingline Exposure and LC Exposure of the Lenders shall
be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender
shall purchase at par such of the Loans of the other Lenders (other than Swingline Loans) as the
Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans
in accordance with its Applicable Percentage.

ARTICLE III.

REPRESENTATIONS AND WARRANTIES

Each of the Company and the Borrower represents and warrants to the Lenders that:

SECTION 3.1. Organization; Powers. Each of the Group Members is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its organization, has
all requisite power and authority to carry on its business as now conducted and, except where the
failure to do so, individually or in the aggregate, could not reasonably be expected to result in a
Material Adverse Effect, is qualified to do business in, and is in good standing in, every
jurisdiction where such qualification is required.

SECTION 3.2. Authorization; Enforceability. The Transactions are within each of the
Loan Party’s powers and have been duly authorized by all necessary action on the part of each Loan
Party. This Agreement has been duly executed and delivered by each of the Company and the Borrower
and constitutes a legal, valid and binding obligation of such Person, enforceable in accordance
with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other
laws affecting creditors’ rights generally and subject to general principles of equity, regardless
of whether considered in a proceeding in equity or at law.

SECTION 3.3. Governmental Approvals; No Conflicts. The Transactions (a) do not
require any consent or approval of, registration or filing with, or any other action by, any
Governmental Authority or any other Person, except such as have been obtained or made and are in
full force and effect, (b) will not violate any applicable law or regulation or the charter,
by-laws or other organizational documents of any Group Member or any order of any Governmental
Authority, (c) will not violate or result in a default under any indenture, agreement or other
instrument binding upon any Group Member or its assets, or give rise to a right thereunder to
require any payment to be made by any Group Member, and (d) will not result in the creation or
imposition of any Lien on any asset of any Group Member.

SECTION 3.4. Financial Condition; No Material Adverse Change. (a) The Company, the
Borrower, and their consolidated Subsidiaries have heretofore furnished to the Lenders their
consolidated balance sheet and statements of income, stockholders equity and cash flows (i) as of
and for the fiscal year ended December 31, 2009, reported on by Deloitte & Touche LLP, independent
public accountants, and (ii) as of and for the fiscal quarter and the portion of the fiscal year
ended June 30, 2010, certified by its chief financial officer. Such financial statements present
fairly, in all material respects, the financial position and results of operations and cash flows
of the Company, the Borrower and their consolidated Subsidiaries as of such dates and for such
periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes
in the case of the statements referred to in clause (ii) above. No Group Member has any material
Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or
unusual forward or long-term commitments, including any interest rate or foreign currency swap or
exchange transaction or other obligation in respect of derivatives, that are not reflected in the
most recent financial statements referred to in this paragraph.

(b) Since June 30, 2010, there has been no material adverse change in the business,
assets, operations or condition, financial or otherwise, of the Company, the Borrower and
their Subsidiaries, taken as a whole.

(c) The pro forma covenant compliance certificate described in Section 4.1(j), a copy
of which has heretofore been furnished to each Lender, has been prepared giving effect (as
if such events had occurred on such date) to (i) the Loans to be made on the Closing Date
and the use of proceeds thereof, (ii) the repayment of Indebtedness under the credit
facility described in Section 4.1(m) and (iii) the payment of fees and expenses in
connection with the foregoing. Such certificate has been prepared based on the best
information available to the Borrower as of the date of delivery thereof, and presents
fairly on a pro forma basis the estimated financial covenant compliance of
Borrower and its consolidated Subsidiaries as at the Closing Date, assuming that the events
specified in the preceding sentence had actually occurred at such date.

SECTION 3.5. Properties. (a) Each of the Group Members has good title to, or valid
leasehold interests in, all its real and personal property material to its business, free and clear
of all Liens except for minor defects in title that do not interfere with its ability to conduct
its business as currently conducted or to utilize such properties for their intended purposes and
other Liens permitted by Section 6.2. Each Group Member has obtained customary title insurance on
its real property.

(b) Each of the Group Members owns, or is licensed to use, all trademarks, tradenames,
copyrights, patents and other intellectual property material to its business, and the use
thereof by the Group Members does not infringe upon the rights of any other Person, except
for any such infringements that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

SECTION 3.6. Litigation and Environmental Matters. (a) There are no actions, suits or
proceedings by or before any arbitrator or Governmental Authority pending against or, to the
knowledge of the Borrower, threatened against or affecting any Group Member (i) as to which there
is a reasonable possibility of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect
(other than the Disclosed Matters) or (ii) that involve this Agreement or the Transactions.

(b) Except for the Disclosed Matters and except with respect to any other matters that,
individually or in the aggregate, could not reasonably be expected to result in a Material
Adverse Effect, none of the Group Members (i) to Borrower’s knowledge after due inquiry, has
failed to comply with any Environmental Law or to obtain, maintain or comply with any
permit, license or other approval required under any Environmental Law, (ii) has become
subject to any Environmental Liability, (iii) has received notice of any claim with respect
to any Environmental Liability or (iv) knows of any basis for any Environmental Liability.

(c) Since the date of this Agreement, there has been no change in the status of the
Disclosed Matters that, individually or in the aggregate, has resulted in, or materially
increased the likelihood of, a Material Adverse Effect.

SECTION 3.7. Compliance with Laws and Agreements. Each of the Group Members is in
compliance with all laws, regulations and orders of any Governmental Authority applicable to it or
its property and all indentures, agreements and other instruments binding upon it or its property,
except where the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No Default has occurred and is continuing
hereunder and no Group Member is in default under or with respect to any contractual obligation
that could, either individually or in the aggregate, result in a Material Adverse Effect.

SECTION 3.8. Investment and Holding Company Status. None of the Group Members is
(a) an “investment company” as defined in, or subject to regulation under, the Investment Company
Act of 1940 or (b) a “holding company” as defined in, or subject to regulation under, the Public

required to have been paid by it, except (a) Taxes that are being contested in good faith by
appropriate proceedings and for which such Group Member, as applicable, has set aside on its books
adequate reserves or (b) to the extent that the failure to do so could not reasonably be expected
to result in a Material Adverse Effect.

SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably expected to occur
that, when taken together with all other such ERISA Events for which liability is reasonably
expected to occur, could reasonably be expected to result in a Material Adverse Effect. The
present value of all accumulated benefit obligations under each Plan (based on the assumptions used
for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the
most recent financial statements reflecting such amounts, exceed by more than $5,000,000 the fair
market value of the assets of such Plan, and the present value of all accumulated benefit
obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of
Financial Accounting Standards No. 87) did not, as of the date of the most recent financial
statements reflecting such amounts, exceed by more than $5,000,000 the fair market value of the
assets of all such underfunded Plans.

SECTION 3.11. Disclosure. The Borrower has disclosed to the Lenders all agreements,
instruments and corporate or other restrictions to which any Group Member is subject, and all other
matters known to it, that, individually or in the aggregate, could reasonably be expected to result
in a Material Adverse Effect. None of the reports, financial statements, certificates or other
information furnished by or on behalf of the Borrower to the Administrative Agent or any Lender in
connection with the negotiation of this Agreement or delivered hereunder (as modified or
supplemented by other information so furnished) contains any material misstatement of fact or omits
to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided that, with respect to
projected financial information, the Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time.

SECTION 3.12. Federal Regulations. No part of the proceeds of any Loans, and no other
extensions of credit hereunder, will be used (a) for “buying” or “carrying” any “margin stock”
within the respective meanings of each of the quoted terms under Regulation U as now and from time
to time hereafter in effect for any purpose that violates the provisions of the Regulations of the
Board or (b) for any purpose that violates the provisions of the Regulations of the Board. If
requested by any Lender or the Administrative Agent, the Borrower will furnish to the
Administrative Agent and each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in Regulation U.

expected to have a Material Adverse Effect: (a) there are no strikes or other labor disputes
against any Group Member pending or, to the knowledge of the Company or the Borrower, threatened;

of the Fair Labor Standards Act or any other applicable laws, regulations and orders of any
Governmental Authority dealing with such matters; and (c) all payments due from any Group Member on
account of employee health and welfare insurance have been paid or accrued as a liability on the
books of the relevant Group Member.

SECTION 3.14. Subsidiaries. Except as disclosed to the Administrative Agent by the

the name and jurisdiction of incorporation of each Subsidiary and, as to each such Subsidiary, the
percentage of each class of Capital Stock owned by any other Group Member and (b) there are no
outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments
(other than stock options granted to employees or directors and directors’ qualifying shares) of
any nature relating to any Capital Stock of the Borrower or any Subsidiary.

SECTION 3.15. Use of Proceeds. The proceeds of the Loans and the Letters of Credit,
shall be used for general corporate purposes of the Borrower and its Subsidiaries, including the
financing of working capital needs, the repayment of Indebtedness of the Borrower and its
Subsidiaries and acquisitions permitted by this Agreement.

SECTION 3.16. Solvency. Each Loan Party is, and after giving effect to the incurrence
of all Indebtedness and obligations being incurred in connection herewith will be and will continue
to be, Solvent.

SECTION 3.17. Status of the Company. The Company (i) is a REIT, (ii) has not revoked
its election to be a REIT, (iii) has not engaged in any “prohibited transactions” as defined in

property of the Group Members and the owner (or ground-lessor) of such Real Property, and
Schedule 3.18(b) sets forth a list of all Unencumbered Assets and the owner (or

for an Unencumbered Asset set forth in the definition thereof. As of the Closing Date, the
Unencumbered Assets listed on Schedule 3.18(b) as delivered by the Borrower on the Closing
Date, in the aggregate, have a Unencumbered Asset Value in excess of $350,000,000.

of net cash and cash equivalents upstream to the Borrower, and the Borrower shall continue to
follow such ordinary course of business. The Company and the Borrower shall not make net transfers

SECTION 5.10. Notices of Asset Sales, Encumbrances or Dispositions. The Borrower
shall deliver to the Administrative Agent and the Lenders written notice not less than five (5)
Business Days prior to a sale, encumbrance with a Lien to secure Indebtedness or other Disposition
of (i) an Unencumbered Asset or (ii) other assets of the Loan Parties or their Subsidiaries, in a
single transaction or series of related transactions, for consideration in excess of $25,000,000,
in each case which is permitted pursuant to Section 6.1(e), Section 6.2(d) or Section 6.9, as

deliver to the Administrative Agent (A) a certificate of a Financial Officer certifying that no

and the financial covenants on a pro-forma basis, including as to the calculation of Unencumbered

To the extent such proposed transaction would result in a Default or an Event of Default, the
Borrower shall apply the proceeds of such transaction (together with such additional amounts as may
be required), to prepay the Obligations in an amount, as determined by the Administrative Agent,
equal to that which would be required to reduce the Obligations so that no Default or Event of
Default would exist.

If such proposed transaction is permitted hereunder, the Administrative Agent shall, at the
Borrower’s expense, take all such action reasonably requested by the Borrower to release the
guarantee obligations under the Guaranty of any Subsidiary Guarantor who shall cease to own any
Unencumbered Assets upon the consummation of such transaction.

Administrative Agent, add one or more new Properties as an Unencumbered Asset or
substitute one or more new Properties for one or more Properties (such newly added

Unencumbered Asset. Any such notice of addition or substitution shall be delivered

Upon delivery of such information, such addition or substitution shall
become effective.

(b) Removals from Unencumbered Assets.

(i) Upon any Unencumbered Asset ceasing to qualify as an Unencumbered Asset,
such Unencumbered Asset shall no longer be included in the calculation of the
Unencumbered Asset Value or Unencumbered NOI. Within ten (10) Business Days after

certificate of a Financial Officer of the Borrower describing such disqualification,
together with a statement of: (i) the identity of the disqualified Unencumbered
Asset, and (ii) the Unencumbered Asset Value attributable to such Unencumbered Asset

Unencumbered Asset in accordance with the terms of the Loan Documents) by delivering
to the Administrative Agent, no later than ten (10) Business Days prior to the date
on which such removal is to be effected (or, in the event such removal shall result

ten (10) Business Days prior to such proposed sale, transfer or Disposition), (x)
certificate of a Financial Officer of the Borrower describing such removal, together

Unencumbered Asset Value attributable to such Unencumbered Asset and (y) the
certificates required by Section 5.12(b)(iii).

(iii) Simultaneously with the delivery of the items required pursuant to
Sections 5.12(b)(i) and (ii), the Borrower shall deliver to the Administrative Agent
a pro forma compliance certificate described in Section 5.1(c) demonstrating, upon
giving effect to such removal, replacement or disqualification, compliance with the
covenants contained in Section 6.13 on a pro forma basis based upon the most recent
financial statements available under Section 5.1(a) or 5.1(b), together with
supporting calculations.

(c) Release of Subsidiary Guarantor. So long as no Event of Default has
occurred and is continuing or would occur after giving effect thereto, following (i) the
Disposition, removal or substitution of an Unencumbered Asset that results in a Subsidiary
Guarantor ceasing to own any Unencumbered Assets and otherwise ceasing to be a Material
Subsidiary or (ii) a Subsidiary Guarantor becoming an Excluded Subsidiary, at the request
and expense of the Borrower and without the need for any consent or approval of the Lenders,
the Administrative Agent shall execute and deliver a release of the Guaranty made by such
Subsidiary Guarantor in a form acceptable to the Borrower and the Administrative Agent.

Guaranty executed by such Material Subsidiary and (ii) the items that would have been delivered
under Sections 4.1(b) and (c) if such Material Subsidiary had been a Subsidiary Guarantor on the
Closing Date. Delivery of the foregoing items shall be made by the Borrower (x) in the case of any
Subsidiary that has become a Material Subsidiary pursuant to the ownership of an Unencumbered
Asset, any acquisition or formation, or as a result of such Subsidiary ceasing to have the
characteristics of an Excluded Subsidiary (as provided in the definition of such term), within ten
(10) days after such ownership, acquisition, formation, or cessation, as the case may be, and (y)
in the case of any existing Subsidiary obtaining the minimum Total Asset Value for a Material
Subsidiary during any fiscal quarter, at the time that the compliance certificate called for by
Section 5.1(c) is required to be delivered to the Administrative Agent in respect of such fiscal
quarter. Additionally, in the event that any Subsidiary of the Borrower or the Company, whether
presently existing or hereafter formed or acquired, which is not a Guarantor at such time, shall
after the date hereof become a guarantor under any existing or future Unsecured Indebtedness of the
Borrower or any Guarantor, then the Borrower shall cause such Subsidiary to execute and deliver the
items described in this Section 5.13.

cause any such Material Indebtedness to become due, or to require the prepayment,

days during which execution shall not be effectively stayed, or any action shall be legally
taken by a judgment creditor to attach or levy upon any assets of the Company, the Borrower
or any Subsidiary to enforce any such judgment;

ARTICLE VIII.

THE ADMINISTRATIVE AGENT

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent
as its agent and authorizes the Administrative Agent to take such actions on its behalf and to
exercise such powers as are delegated to the Administrative Agent by the terms hereof, together
with such actions and powers as are reasonably incidental thereto.

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

The Administrative Agent shall not have any duties or obligations except those expressly set
forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall
not be subject to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby that the Administrative Agent is required to exercise in writing as
directed by the Required Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 9.2), and (c) except as expressly set
forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable
for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries
that is communicated to or obtained by the bank serving as Administrative Agent or any of its
Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or
not taken by it with the consent or at the request of the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.2)
or in the absence of its own gross negligence or wilful misconduct, and any action so taken or not
taken at the direction of the Required Lenders (or such other number or percentage of the Lenders
as shall be necessary under the circumstances as provided in Section 9.2) shall be binding on all
Lenders. The Administrative Agent shall be deemed not to have knowledge of any Default (other than
a Default under Section 7(a) or Section 7(b) (with respect to interest or fees)) unless and until
written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the
Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into
(i) any statement, warranty or representation made in or in connection with this Agreement,
(ii) the contents of any certificate, report or other document delivered hereunder or in connection
herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent.

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

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

Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this paragraph, the Administrative Agent may (a) resign at any time by notifying the Lenders, the
Issuing Bank and the Borrower or (b) be removed by written notice of the Required Lenders with the
consent of the Borrower if the Administrative Agent engages in gross negligence or willful
misconduct in the performance of its duties under the Loan Document. Upon any such resignation or
removal, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a
successor. If no successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative Agent gives notice of
its resignation or the Required Lenders give notice of the Administrative Agent’s removal, as
applicable, then the retiring or removed Administrative Agent may, on behalf of the Lenders and the
Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in New
York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor, such successor shall succeed to and become vested
with all the rights, powers, privileges and duties of the retiring or removed Administrative Agent,
and the retiring or removed Administrative Agent shall be discharged from its duties and
obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall
be the same as those payable to its predecessor unless otherwise agreed between the Borrower and
such successor. After the Administrative Agent’s resignation or removal hereunder, the provisions
of this Article and Section 9.3 shall continue in effect for the benefit of such retiring or
removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any
actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

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

SECTION 9.2. Waivers; Amendments. (a) No failure or delay by the Administrative
Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights and remedies of
the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of
this Agreement or consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver
or consent shall be effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of
Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative
Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified
except pursuant to an agreement or agreements in writing entered into by the Borrower and
the Required Lenders or by the Borrower and the Administrative Agent with the consent of the
Required Lenders; provided that no such agreement shall (i) increase the Commitment
of any Lender without the written consent of such Lender, (ii) reduce the principal amount
of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees
payable hereunder, without the written consent of each Lender affected thereby, (iii)
postpone the scheduled date of payment of the principal amount of any Loan or LC
Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount
of, waive or excuse any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (iv) change Section
2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required
thereby, without the written consent of each Lender, (v) change any of the provisions of
this Section or the definition of “Required Lenders” or any other provision hereof
specifying the number or percentage of Lenders required to waive, amend or modify any rights
hereunder or make any determination or grant any consent hereunder, without the written
consent of each Lender or (vi) release the Company from its obligations under the Guaranty,
or release substantially all of the Subsidiary Guarantors from their obligations under the
Guaranty (except as otherwise provided in Section 5.12), in each case, without the written
consent of each Lender; provided further that (x) no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative Agent, the
Issuing Bank or the Swingline Lender hereunder without the prior written consent of the
Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, (y) no
such agreement shall amend or modify Section 2.19 without the prior written consent of the
Administrative Agent, the Swingline Lender and the Issuing Bank, and (z) any provision of
this Agreement or any other Loan Document may be amended by an agreement in writing entered
into by the Company, the Borrower and the Administrative Agent to cure any ambiguity,
omission, defect or inconsistency so long as, in each case, the Lenders shall have received
at least five (5) Business Days’ prior written notice thereof and the Administrative Agent
shall not have received, within five (5) Business Days of the date of such notice to the
Lenders, a written notice from the Required Lenders stating that the Required Lenders object
to such amendment.

SECTION 9.3. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all
reasonable out-of-pocket expenses incurred by each of the Administrative Agent, the Joint Lead
Arrangers and their Affiliates, including the reasonable fees, charges and disbursements of counsel
for the Administrative Agent, in connection with the syndication of the credit facilities provided
for herein, the preparation and administration of this Agreement or any amendments, modifications
or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby
shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in
connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand
for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent,
the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for
the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or
protection of its rights in connection with this Agreement, including its rights under this
Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all
such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect
of such Loans or Letters of Credit. Notwithstanding the foregoing, in no event shall Borrower be
responsible to pay any costs or expenses of the Administrative Agent or the Lenders related to any
assignment or participation of the Loans.

(b) The Borrower shall indemnify the Administrative Agent, the Issuing Bank, each Joint
Lead Arranger and each Lender, and each Related Party of any of the foregoing Persons (each
such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses, including the
fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted
against any Indemnitee arising out of, in connection with, or as a result of (i) the
execution or delivery of this Agreement or any agreement or instrument contemplated hereby,
the performance by the parties hereto of their respective obligations hereunder or the
consummation of the Transactions or any other transactions contemplated hereby, (ii) any
Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the
Issuing Bank to honor a demand for payment under a Letter of Credit if the documents
presented in connection with such demand do not strictly comply with the terms of such
Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on
or from any property owned or operated by the Borrower or any of its Subsidiaries, or any
Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or
(iv) any actual or prospective claim, litigation, investigation or proceeding relating to
any of the foregoing, whether based on contract, tort or any other theory and regardless of
whether any Indemnitee is a party thereto; provided that such indemnity shall not,
as to any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses (i) are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Indemnitee, or (ii) relate solely to disputes among the Lenders and/or
the Administrative Agent or (iii) are determined by a court of competent jurisdiction by
final and non-appealable judgment to have resulted from the breach in bad faith of such
Indemnitee’s obligations to the Borrower hereunder.

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

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

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

SECTION 9.4. Successors and Assigns. (a) The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of
Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no
Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance
with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer
upon any Person (other than the parties hereto, their respective successors and assigns permitted
hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants
(to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated
hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

(A) the Borrower, provided that no consent of the Borrower
shall be required for an assignment to a Lender, an Affiliate of a Lender,
an Approved Fund or, if an Event of Default has occurred and is continuing,
any other assignee; and provided further that the Borrower will be deemed to
be reasonable in withholding its consent to any assignee which is not an
Eligible Assignee;

(B) the Administrative Agent, provided that no consent of the
Administrative Agent shall be required for an assignment of any Commitment
to an assignee that is a Lender with a Commitment immediately prior to
giving effect to such assignment; and

(C) the Issuing Bank and the Swingline Lender.

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

(A) except in the case of an assignment to a Lender or an Affiliate of
a Lender or an assignment of the entire remaining amount of the assigning
Lender’s Commitment or Loans of any Class, the amount of the Commitment or
Loans of the assigning Lender subject to each such assignment (determined as
of the date the Assignment and Assumption with respect to such assignment is
delivered to the Administrative Agent) shall not be less than $5,000,000
unless each of the Borrower and the Administrative Agent otherwise consent,
provided that no such consent of the Borrower shall be required if
an Event of Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender’s rights and obligations
under this Agreement, provided that this clause shall not be
construed to prohibit the assignment of a proportionate part of all the
assigning Lender’s rights and obligations in respect of one Class of
Commitments or Loans;

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

(D) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire in which the assignee
designates one or more Credit Contacts to whom all syndicate-level
information (which may contain material non-public information about the
Loan Parties and their related parties or their respective securities) will
be made available and who may receive such information in accordance with
the assignee’s compliance procedures and applicable laws, including Federal
and state securities laws.

For the purposes of this Section 9.4(b), the term “Approved Fund” has the
following meaning:

“Approved Fund” means any Person (other than a natural person) that is engaged
in making, purchasing, holding or investing in bank loans and similar extensions of credit
in the ordinary course of its business and that is administered or managed by (a) a Lender,
(b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers
or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv)
of this Section, from and after the effective date specified in each Assignment and
Assumption the assignee thereunder shall be a party hereto and, to the extent of the
interest assigned by such Assignment and Assumption, have the rights and obligations
of a Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, be released from
its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender’s rights and obligations under this
Agreement, such Lender shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.3). Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this Section 9.4 shall be treated for purposes of this Agreement as a
sale by such Lender of a participation in such rights and obligations in accordance
with paragraph (c) of this Section.

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

(v) Upon its receipt of a duly completed Assignment and Assumption executed by
an assigning Lender and an assignee, the assignee’s completed Administrative
Questionnaire (unless the assignee shall already be a Lender hereunder), the
processing and recordation fee referred to in paragraph (b) of this Section and any
written consent to such assignment required by paragraph (b) of this Section, the
Administrative Agent shall accept such Assignment and Assumption and record the
information contained therein in the Register; provided that if either the
assigning Lender or the assignee shall have failed to make any payment required to
be made by it pursuant to Section 2.5(c), 2.6(d) or (e), 2.7(b), 2.18(d) or 9.3(c),
the Administrative Agent shall have no obligation to accept such Assignment and
Assumption and record the information therein in the Register unless and until such
payment shall have been made in full, together with all accrued interest thereon.
No assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

(c) (i)Any Lender may, without the consent of the Borrower, the Administrative Agent,
the Issuing Bank or the Swingline Lender, sell participations to one or more banks or other
entities (other than the Company, the Borrower and their Affiliates) (a
“Participant”) in all or a portion of such Lender’s rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans owing to it);
provided that (A) such Lender’s obligations under this Agreement shall remain
unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations, (C) the Borrower, the Administrative Agent, the Issuing
Bank and the other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement, and (D) Borrower
shall not be responsible for any cost or expense of the Lenders or the Administrative Agent
related to any participation of the Loans or any increased cost or expense incurred by any
Lender as a result of such participation thereafter, except as expressly provided herein.
Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this Agreement;
provided that such agreement or instrument may provide that such Lender will not,
without the consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 9.2(b) that affects such Participant. Subject to
paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be
entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 9.8 as though it were a Lender, provided such Participant agrees to be
subject to Section 2.18(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under
Section 2.15 or 2.17 than the applicable Lender would have been entitled to receive
with respect to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Borrower’s prior written consent.
A Participant that would be a Foreign Lender if it were a Lender shall not be
entitled to the benefits of Section 2.17 unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit
of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(d) Any Lender may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such Lender, including
without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank,
and this Section shall not apply to any such pledge or assignment of a security interest;
provided that no such pledge or assignment of a security interest shall release a
Lender from any of its obligations hereunder or substitute any such pledgee or assignee for
such Lender as a party hereto.

SECTION 9.5. Survival. All covenants, agreements, representations and warranties made
by the Borrower herein and in the certificates or other instruments delivered in connection with
or pursuant to this Agreement shall be considered to have been relied upon by the other parties
hereto and shall survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by any such other party
or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender
may have had notice or knowledge of any Default or incorrect representation or warranty at the time
any credit is extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount payable under this
Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the
Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.3
and Article VIII shall survive and remain in full force and effect regardless of the consummation
of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination
of the Letters of Credit and the Commitments or the termination of this Agreement or any provision
hereof.

SECTION 9.6. Counterparts; Integration; Effectiveness. This Agreement may be executed
in counterparts (and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract.
This Agreement and any separate letter agreements with respect to fees payable to the
Administrative Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Except as provided in Section 4.1, this Agreement shall
become effective when it shall have been executed by the Administrative Agent and when the
Administrative Agent shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy shall be effective as
delivery of a manually executed counterpart of this Agreement.

SECTION 9.7. Severability. Any provision of this Agreement held to be invalid,
illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the
extent of such invalidity, illegality or unenforceability without affecting the validity, legality
and enforceability of the remaining provisions hereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.8. Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time
to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general
or special, time or demand, provisional or final) at any time held and other obligations at any
time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against
any of and all the obligations of the Borrower now or hereafter existing under this Agreement held
by such Lender, irrespective of whether or not such Lender shall have made any demand under this
Agreement and although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of setoff) which such
Lender may have.

SECTION 9.9. Governing Law; Jurisdiction; Consent to Service of Process. (a) This
Agreement shall be construed in accordance with and governed by the law of the State of New York.

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

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

(d) Each party to this Agreement irrevocably consents to service of process in the
manner provided for notices in Section 9.1. Nothing in this Agreement will affect the right
of any party to this Agreement to serve process in any other manner permitted by law.

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

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

SECTION 9.12. Confidentiality. (a) Each of the Administrative Agent, the Issuing Bank
and the Lenders agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its and its Affiliates’ directors, officers,
employees and agents, including accountants, legal counsel and other advisors (it being understood
that the Persons to whom such disclosure is made will be informed of the confidential nature of
such Information and instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any
subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with
the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement
or the enforcement of rights hereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations under this Agreement or
(ii) any actual or prospective counterparty (or its advisors) to any swap or derivative
transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or
(h) to the extent such Information (i) becomes publicly available other than as a result of a
breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or
any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of
this Section, “Information” means all information received from the Borrower relating to
the Group Members or their business, other than any such information that is available to the
Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure
by the Borrower; provided that, in the case of information received from the Borrower after
the date hereof, such information is clearly identified at the time of delivery as confidential.
Any Person required to maintain the confidentiality of Information as provided in this Section
shall be considered to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such Person would accord
to its own confidential information.

(b) EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.12(a) FURNISHED
TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE
LOAN PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, AND CONFIRMS THAT IT
HAS DEVELOPED COMPLIANCE PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND
THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES
AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.

(c) ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE
BORROWER OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF ADMINISTERING, THIS
AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY CONTAIN MATERIAL NON-PUBLIC
INFORMATION ABOUT THE LOAN PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES.
ACCORDINGLY, EACH LENDER REPRESENTS TO THE BORROWER AND THE ADMINISTRATIVE AGENT THAT IT
HAS IDENTIFIED IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE
INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS
COMPLIANCE PROCEDURES AND APPLICABLE LAW.

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

SECTION 9.14. USA PATRIOT Act. Each Lender that is subject to the requirements of the
USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby
notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain,
verify and record information that identifies the Loan Parties, which information includes the name
and address of the Loan Parties and other information that will allow such Lender to identify the
Loan Parties in accordance with the Act.

GUARANTY

THIS GUARANTY dated as of October 13, 2010, executed and delivered by each of the undersigned
and the other Persons from time to time party hereto (all of the undersigned, together with such
other Persons each a “Guarantor” and collectively, the “Guarantors”) in favor of (a) JPMORGAN CHASE
BANK, N.A., in its capacity as Administrative Agent (the “Agent”) for the Lenders under that
certain Credit Agreement dated as of October 13, 2010 (as amended, restated, supplemented or
otherwise modified from time to time, the “Credit Agreement”), by and among HEALTHCARE TRUST OF
AMERICA HOLDINGS, LP, a Delaware limited partnership (the “Borrower”), HEALTHCARE TRUST OF AMERICA,
INC. (the “Company”), the financial institutions party thereto and their respective assignees (the
“Lenders”), the Agent, and the other parties thereto, and (b) the Lenders, the Issuing Bank and the
Swingline Lender (the parties described in (a) and (b) are hereinafter referred to collectively as
the “Credit Parties”).

WHEREAS, pursuant to the Credit Agreement, the Credit Parties have agreed to make available to
the Borrower certain financial accommodations on the terms and conditions set forth in the Credit
Agreement;

WHEREAS, either (i) Borrower is the owner, directly or indirectly, of 100% of the issued and
outstanding Equity Interests in each Guarantor, or (ii) the Company is the owner, directly or
indirectly of a substantial amount of the Equity Interests in the Borrower;

WHEREAS, the Borrower and each of the Guarantors, though separate legal entities, are mutually
dependent upon each other in the conduct of their respective businesses as an integrated operation
and have determined it to be in their mutual best interests to obtain financing from the Credit
Parties through their collective efforts;

WHEREAS, each Guarantor acknowledges that it will receive direct and indirect benefits from
the Credit Parties making such financial accommodations available to the Borrower under the Credit
Agreement and, accordingly, each Guarantor is willing to guarantee the Borrower’s obligations to
the Credit Parties on the terms and conditions contained herein; and

WHEREAS, each Guarantor’s execution and delivery of this Guaranty is a condition to the Credit
Parties making, and continuing to make, such financial accommodations to the Borrower.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged by each Guarantor, each Guarantor agrees as follows:

Section 1. Guaranty. Each Guarantor hereby absolutely, irrevocably and
unconditionally guaranties the due and punctual payment and performance when due and payable,
whether at stated maturity, by acceleration or otherwise, of all of the following (collectively
referred to as the “Guarantied Obligations”): (a) all Obligations, and liabilities of whatever
nature, whether now existing or hereafter incurred, owing by the Borrower to any Credit Party under
or in connection with the Credit Agreement and any other Loan Document, including without
limitation, the repayment of all principal of the Revolving Loans, Swingline Loans and the
reimbursement obligations under Section 2.6(e) of the Credit Agreement (the “Reimbursement
Obligations”), and the payment of all interest, including, without limitation, interest accruing
after the commencement of a proceeding under bankruptcy, insolvency, or similar laws of any
jurisdiction at the rate or rates provided in the loan documents, fees, charges, expenses,
indemnification, attorneys’ fees and other amounts payable to any Credit Party thereunder or in
connection therewith whether created directly or acquired by the credit parties by assignment or
otherwise, whether matured or unmatured and whether absolute or contingent; (b) any and all
extensions, renewals, modifications, amendments or substitutions of the foregoing; (c) all
expenses, including, without limitation, reasonable attorneys’ fees and disbursements, that are
incurred by the Credit Parties in the enforcement of any of the foregoing or any obligation of such
Guarantor hereunder; and (d) all other Obligations.

Section 2. Guaranty of Payment and Not of Collection. This Guaranty is a guaranty of
payment and performance, and not of collection, and a debt of each Guarantor for its own account.
Accordingly, none of the Credit Parties shall be obligated or required before enforcing this
Guaranty against any Guarantor: (a)  to pursue any right or remedy any of them may have against the
Borrower, any other Guarantor or any other Person or commence any suit or other proceeding against
the Borrower, any other Guarantor or any other Person in any court or other tribunal; (b) to make
any claim in a liquidation or bankruptcy of the Borrower, any other Guarantor or any other Person;
or (c) to make demand of the Borrower, any other Guarantor or any other Person or to enforce or
seek to enforce or realize upon any collateral security held by a Credit Party which may secure any
of the Guarantied Obligations.

Section 3. Guaranty Absolute. Each Guarantor guarantees that the Guarantied
Obligations will be paid strictly in accordance with the terms of the documents evidencing the
same, regardless of any applicable law now or hereafter in effect in any jurisdiction affecting any
of such terms or the rights of the Credit Parties with respect thereto. The liability of each
Guarantor under this Guaranty shall be absolute, irrevocable 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) (i) any change in the amount, interest rate or due date or other term of any of the
Obligations, (ii) any change in the time, place or manner of payment of all or any portion of the
Obligations, (iii) any amendment or waiver of, or consent to the departure from or other indulgence
with respect to, the Credit Agreement, any other Loan Document, or any other document or instrument
evidencing or relating to any Guarantied Obligations, or (iv) any waiver, renewal, extension,
addition, or supplement to, or deletion from, or any other action or inaction under or in respect
of, the Credit Agreement, any of the other Loan Documents, or any other documents, instruments or
agreements relating to the Guarantied Obligations or any other instrument or agreement referred to
therein or evidencing any Guarantied Obligations or any assignment or transfer of any of the
foregoing;

(b) any illegality, lack of validity or enforceability of the Credit Agreement, any of the
other Loan Documents, or any other document, instrument or agreement referred to therein or
evidencing any Guarantied Obligations or any assignment or transfer of any of the foregoing;

(c) any furnishing to a Credit Party of any security for the Guarantied Obligations, or any
sale, exchange, release or surrender of, or realization on, any collateral securing any of the
Obligations;

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

(e) any act or failure to act by the Borrower, any other obligor or any other Person which may
adversely affect such Guarantor’s subrogation rights, if any, against the Borrower to recover
payments made under this Guaranty;

(f) any nonperfection or impairment of any security interest or other Lien on any collateral,
if any, securing in any way any of the Obligations;

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

(h) to the fullest extent permitted by law, any statute of limitations in any action hereunder
or for the collection of the Notes or the Reimbursement Obligations or for the payment or
performance of the Guarantied Obligations;

(i) the incapacity, lack of authority, death or disability of Borrower or any other person or
entity, or the failure of any Credit Party to file or enforce a claim against the estate (either in
administration, bankruptcy or in any other proceeding) of the Borrower or any Guarantor or any
other person or entity;

(j) the dissolution or termination of existence of the Borrower, any Guarantor or any other
Person;

(k) the voluntary or involuntary liquidation, sale or other disposition of all or
substantially all of the assets of the Borrower or any other Person;

(l) the voluntary or involuntary receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, assignment, composition, or readjustment of, or any similar
proceeding affecting, the Borrower or any Guarantor or any other person, or any of the Borrower’s
or any Guarantor’s or any other Person’s or entity’s properties or assets;

(m) the damage, destruction, condemnation, foreclosure or surrender of all or any part of any
Property or any of the improvements located thereon;

(n) the failure of a Credit Party to give notice of the existence, creation or incurring of
any new or additional indebtedness or obligation or of any action or nonaction on the part of any
other person whomsoever in connection with any Guarantied Obligation;

(o) any failure or delay of a Credit Party to commence an action against the Borrower or any
other Person, to assert or enforce any remedies against the Borrower under the Notes or the Loan
Documents, or to realize upon any security;

(p) any failure of any duty on the part of a Credit Party to disclose to any Guarantor any
facts it may now or hereafter know regarding the Borrower, any other Person or the Properties or
any of the improvements located thereon, whether such facts materially increase the risk to
Guarantors or not;

(q) failure to accept or give notice of acceptance of this Guaranty by the Credit Parties;

(r) other than as expressly required hereunder, the failure to make or give notice of
presentment and demand for payment of any of the indebtedness or performance of any of the
Guarantied Obligations;

(s) other than as expressly required hereunder, the failure to make or give protest and notice
of dishonor or of default to Guarantors or to any other party with respect to the indebtedness or
performance of the Guarantied Obligations;

(t) except as otherwise specifically provided in this Guaranty, any and all other notices
whatsoever to which Guarantors might otherwise be entitled;

(u) any lack of diligence by the Credit Parties in collection, protection or realization upon
any collateral securing the payment of the indebtedness or performance of the Guaranteed
Obligations;

(v) the compromise, settlement, release or termination of any or all of the obligations of the
Borrower under the Notes or the Loan Documents;

(w) any transfer by the Borrower or any other Person of all or any part of the security
encumbered by the Loan Documents;

(x) claims or rights of set-off defense or counterclaim whatsoever, whether based in contract,
tort, or any other theory, that any Guarantor may have provided, however, that the foregoing shall
not be deemed a waiver of any Guarantor’s right to assert any compulsory counterclaim, if such
counterclaim is compelled under local law or rule of procedure, nor shall the foregoing be deemed a
waiver of any Guarantor’s right to assert any claim which would constitute a defense, setoff,
counterclaim or crossclaim of any nature whatsoever against Agent or any Lender in any separate
action or proceeding;

(y) any law, regulation, decree or order of any jurisdiction or any event affecting any
provision of the Guarantied Obligations; or

(z) to the fullest extent permitted by law, any other legal, equitable or surety defenses
whatsoever to which Guarantors might otherwise be entitled or any other circumstances which might
otherwise constitute a discharge of a Guarantor (other than indefeasible payment in full or as to a
Guarantor, a release of such Guarantor pursuant to and as provided in the Credit Agreement or as
approved by all of the Lenders), it being the intention that the obligations of Guarantors
hereunder are absolute, unconditional and irrevocable.

Section 4. Action with Respect to Guarantied Obligations. The Credit Parties may, at
any time and from time to time, without the consent of, or notice to, any Guarantor, and without
discharging any Guarantor from its obligations hereunder, take any and all actions described in
Section 3 and may otherwise: (a) amend, modify, alter or supplement the terms of any of the
Obligations, including, but not limited to, extending or shortening the time of payment of any of
the Obligations or changing the interest rate that may accrue on any of the Obligations; (b) amend,
modify, alter or supplement the Credit Agreement or any other Loan Document; (c) sell, exchange,
release or otherwise deal with all, or any part, of any collateral securing any of the Obligations;
(d) release any other obligor or other Person liable in any manner for the payment or collection of
the Guarantied Obligations; (e) exercise, or refrain from exercising, any rights against the
Borrower, any other Guarantor or any other Person; and (f) apply any sum, by whomsoever paid or
however realized, to the Guarantied Obligations in such order as the Agent shall elect.

Section 5. Representations and Warranties. Each Guarantor hereby makes to the Credit
Parties all of the representations and warranties made by the Borrower with respect to or in any
way relating to such Guarantor in the Credit Agreement and the other Loan Documents, as if the same
were set forth herein in full. In addition to making all of the representations and warranties
made by the Borrower with respect to each Guarantor in the Credit Agreement, the Guarantor
represents and warrants that: (a) this Guaranty: (i) has been authorized by all necessary action of
the Guarantor; (ii) (a) does not conflict with or result in a breach of, or constitute a default
under, any agreement or other instrument to which any Guarantor is a party; and (b) does not
violate any applicable law applicable to the Guarantor; (iii) does not require approval from any
Governmental Authority relating to any Guarantor; and (iv) is the legal, valid and binding
obligation of the Guarantor enforceable against the Guarantor in accordance with its terms except
to the extent that enforcement may be limited by applicable bankruptcy, insolvency and other
similar laws affecting creditor’s rights generally and the availability of equitable remedies for
the enforcement of certain obligations (other than the payment of principal) contained herein or
therein may be limited by equitable principles generally; and (b) in executing and delivering this
Guaranty, the Guarantor has (i) without reliance on the Credit Parties or any information received
from the Credit Parties and based upon such documents and information it deems appropriate, made an
independent investigation of the transactions contemplated hereby and the Borrower, the Borrower’s
business, assets, operations, prospects and condition, financial or otherwise, and any
circumstances which may bear upon such transactions, the Borrower or the obligations and risks
undertaken herein with respect to the Guaranteed Obligations; (ii) adequate means to obtain from
the Borrower on a continuing basis information concerning the Borrower; (iii) has full and complete
access to the Credit Agreement and the other Loan Documents; and (iv) not relied and will not rely
upon any representations or warranties of the Credit Parties not embodied herein or any acts
heretofore or hereafter taken by the Credit Parties (including but not limited to any review by the
Credit Parties of the affairs of the Borrower). The Company hereby represents and warrants that
the Company owns (directly or indirectly) a substantial amount of the stock or other ownership
interests of the Borrower and is financially interested in its affairs. All representations and
warranties made under this Guaranty shall be deemed to be made at and as of the date of this
Guaranty, the Effective Date and the date of the occurrence of the making of any Loan, the
conversion of any Loan, or the issuance of any Letter of Credit, except to the extent that such
representations and warranties expressly relate solely to an earlier date (in which case such
representations and warranties shall have been true and accurate on and as of such earlier date)
and except for changes in factual circumstances specifically permitted hereunder or under the
Credit Agreement.

Section 6. Covenants. Each Guarantor will perform and comply with all covenants
applicable to such Guarantor, or which the Borrower is required to cause such Guarantor to comply
with under the terms of the Credit Agreement or any of the other Loan Documents as if the same were
more fully set forth herein.

Section 7. Waiver. Each Guarantor, to the fullest extent permitted by applicable law,
hereby waives, other than as expressly required hereunder, notice of acceptance hereof or any
presentment, demand, protest or notice of any kind, and any other act or thing, or omission or
delay to do any other act or thing, which in any manner or to any extent might vary the risk of
such Guarantor or which otherwise might operate to discharge such Guarantor from its obligations
hereunder. The Guarantor also waives the right to require the Agent to proceed first against the
Borrower upon the Guaranteed Obligations before proceeding against the Guarantor hereunder.

Section 8. Reinstatement of Guarantied Obligations. If a claim is ever made on a
Credit Party for repayment or recovery of any amount or amounts received in payment or on account
of any of the Guarantied Obligations, and such Credit Party repays all or part of said amount by
reason of (a) any judgment, decree or order of any court or administrative body of competent
jurisdiction, or (b) any settlement or compromise of any such claim effected by such Credit Party
with any such claimant (including the Borrower or a trustee in bankruptcy for the Borrower), 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, any release herefrom, or
the cancellation of the Credit Agreement, any of the other Loan Documents, or any other instrument
evidencing any liability of the Borrower, this Guaranty shall continue to be effective or be
reinstated and such Guarantor shall be and remain liable to the Credit Parties for the amounts so
repaid or recovered to the same extent as if such amount had never originally been paid to such
Credit Party.

Section 9. Avoidance. As of any date of determination, the maximum obligation of each
Guarantor shall equal, but not exceed, the maximum amount of liability which could be asserted
against such Guarantor hereunder (or any other obligations of such Guarantor to the Credit Parties)
without (i) rendering such Guarantor “insolvent” within the meaning of Section 101(32) of the
Federal Bankruptcy Code (the “Bankruptcy Code”) or Section 2 of either the Uniform Fraudulent
Transfer Act (the “UFTA”) or the Uniform Fraudulent Conveyance Act (the “UFCA”) or the fraudulent
conveyance and transfer laws of the State of New York or such other jurisdiction whose laws shall
be determined to apply to the transactions contemplated by this Agreement (the “Applicable State
Fraudulent Conveyance Laws”), (ii) leaving such Guarantor with unreasonably small capital, within
the meaning of Section 548 of the Bankruptcy Code or Section 4 of the UFTA or Section 5 of the UFCA
or the Applicable State Fraudulent Conveyance Laws, or (iii) leaving such Guarantor unable to pay
its debts as they become due within the meaning of Section 548 of the Bankruptcy Code or Section 4
of the UFTA or Section 6 of the UFCA or the Applicable State Fraudulent Conveyance Laws.  This
Section is intended solely to preserve the rights of the Credit Parties hereunder to the maximum
extent that would not cause the obligations of each Guarantor hereunder to be unenforceable or
subject to avoidance, and neither a Guarantor nor any other Person shall have any right or claim
under this Section as against the Credit Parties that would not otherwise be available to such
Person. 

Section 10. No Contest with Credit Parties; Subordination. So long as any Guarantied
Obligation remains unpaid or undischarged, Guarantors will not, by paying any sum recoverable
hereunder (whether or not demanded by any Credit Party) or by any means or on any other ground,
claim any set-off or counterclaim against the Borrower in respect of any liability of Guarantors to
the Borrower or, in proceedings under federal bankruptcy law or insolvency proceedings of any
nature, prove in competition with any Credit Party in respect of any payment hereunder or be
entitled to have the benefit of any counterclaim or proof of claim or dividend or payment by or on
behalf of the Borrower or the benefit of any other security for any obligation hereby guaranteed
which, now or hereafter, any Credit Party may hold or in which it may have any share. For so long
as the Obligations remain outstanding, Guarantors hereby expressly waive any right of contribution
from or indemnity against the Borrower, whether at law or in equity, arising from any payments made
by Guarantors pursuant to the terms of this Guaranty, and Guarantors acknowledge that Guarantors
have no right whatsoever to proceed against the Borrower for reimbursement of any such payments.
For so long as the Obligations remain outstanding, in connection with the foregoing, Guarantors
expressly waive any and all rights of subrogation to the Credit Parties against the Borrower, and
Guarantors hereby waive any rights to enforce any remedy which a Credit Party may have against the
Borrower and any rights to participate in any collateral for the Borrower’s obligations under the
Loan Documents. Guarantors hereby subordinate any and all indebtedness of the Borrower now or
hereafter owed to Guarantors to all indebtedness of the Borrower to the Credit Parties, and agree
with the Credit Parties that (a) Guarantors shall not demand or accept any payment from the
Borrower on account of such indebtedness, (b) Guarantors shall not claim any offset or other
reduction of Guarantors’ obligations hereunder because of any such indebtedness, and (c) Guarantors
shall not take any action to obtain any interest in any of the security described in and encumbered
by the Loan Documents because of any such indebtedness; provided, however, that, if
a Credit Party so requests, such indebtedness shall be collected, enforced and received by
Guarantors as trustee for the Credit Parties and be paid over to the Credit Parties on account of
the indebtedness of the Borrower to the Credit Parties, but without reducing or affecting in any
manner the liability of Guarantors under the other provisions of this Guaranty except to the extent
the principal amount of such outstanding indebtedness shall have been reduced by such payment.

Section 11. Payments Free and Clear. All sums payable by each Guarantor hereunder,
whether of principal, interest, fees, expenses, premiums or otherwise, shall be paid in full,
without set-off or counterclaim or any deduction or withholding whatsoever (including any Taxes),
and if any Guarantor is required by applicable law or by a Governmental Authority to make any such
deduction or withholding, such Guarantor shall pay to the Credit Parties such additional amount as
will result in the receipt by the Credit Parties of the full amount payable hereunder had such
deduction or withholding not occurred or been required. Whenever any Taxes are paid by the
Guarantor, as promptly as possible thereafter, the Guarantor shall send the Agent an official
receipt showing payment thereof, together with such additional documentary evidence as may be
required from time to time by the Agent.

Section 12. Set-off. In addition to any rights now or hereafter granted under any of
the other Loan Documents or applicable law and not by way of limitation of any such rights, each
Guarantor hereby authorizes the Credit Parties, at any time during the continuance of an Event of
Default, without any prior notice to such Guarantor or to any other Person, any such notice being
hereby expressly waived, but in the case of a Credit Party other than the Agent subject to receipt
of the prior written consent of the Agent exercised in its sole discretion, 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) and any other
indebtedness at any time held or owing by such Credit Party or any affiliate of such Credit Party,
to or for the credit or the account of such Guarantor held at any of the offices of the Agent or
J.P. Morgan Securities, Inc., against and on account of any of the Guarantied Obligations, although
such obligations shall be contingent or unmatured. Each Guarantor agrees, to the fullest extent
permitted by applicable law, that any Participant may exercise rights of set off or counterclaim
and other rights with respect to its participation as fully as if such Participant were a direct
creditor of such Guarantor in the amount of such participation. The foregoing shall not apply to
any account governed by a written agreement containing an express waiver by such Participant of
such Participant’s rights of setoff.

Section 13. Business Failure, Bankruptcy or Insolvency. In the event of the business
failure of any Guarantor or if there shall be pending any bankruptcy or insolvency case or
proceeding with respect to any Guarantor under federal bankruptcy law or any other applicable law
or in connection with the insolvency of any Guarantor, or if a liquidator, receiver, or trustee
shall have been appointed for any Guarantor or any Guarantor’s properties or assets, the Credit
Parties may file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of such Person allowed in any proceedings relative to such
Guarantor, or any of such Guarantor’s properties or assets, and, irrespective of whether the
indebtedness or other obligations of the Borrower guaranteed hereby shall then be due and payable,
by declaration or otherwise, the Credit Parties shall be entitled and empowered to file and prove a
claim for the whole amount of any sums or sums owing with respect to the indebtedness or other
obligations of the Borrower guaranteed hereby, and to collect and receive any moneys or other
property payable or deliverable on any such claim. Guarantors covenant and agree that upon the
commencement of a voluntary or involuntary bankruptcy proceeding by or against the Borrower,
Guarantors shall not seek a supplemental stay or otherwise pursuant to 11 U.S.C. §105 or any other
provision of the Bankruptcy Reform Act of 1978, as amended, or any other debtor relief law (whether
statutory, common law, case law, or otherwise) of any jurisdiction whatsoever, now or hereafter in
effect, which may be or become applicable, to stay, interdict, condition, reduce or inhibit the
ability of the Credit Parties to enforce any rights of such Person against Guarantors by virtue of
this Guaranty or otherwise. If a Credit Party is prevented under applicable law or otherwise from
demanding or accelerating payment of any of the Guarantied Obligations by reason of any automatic
stay or otherwise, the Credit Parties shall be entitled to receive from each Guarantor, upon demand
therefor, the sums which otherwise would have been due had such demand or acceleration occurred.

SECTION 14. ADDITIONAL GUARANTORS; RELEASE OF GUARANTORS. SECTION 5.13 OF THE CREDIT
AGREEMENT PROVIDES THAT CERTAIN SUBSIDIARIES MUST BECOME GUARANTORS BY, AMONG OTHER THINGS,
EXECUTING AND DELIVERING TO AGENT A COPY OF THIS GUARANTY. ANY SUBSIDIARY WHICH EXECUTES AND
DELIVERS TO THE AGENT THIS GUARANTY SHALL BE A GUARANTOR FOR ALL PURPOSES HEREUNDER. UNDER CERTAIN
CIRCUMSTANCES DESCRIBED IN SECTION 5.12(C) OF THE CREDIT AGREEMENT, CERTAIN SUBSIDIARIES MAY OBTAIN
FROM THE AGENT A WRITTEN RELEASE FROM THIS GUARANTY PURSUANT TO THE PROVISIONS OF SUCH SECTION, AND
UPON OBTAINING SUCH WRITTEN RELEASE, ANY SUCH SUBSIDIARY SHALL NO LONGER BE A GUARANTOR HEREUNDER.
EACH OTHER GUARANTOR CONSENTS AND AGREES TO ANY SUCH RELEASE AND AGREES THAT NO SUCH RELEASE SHALL
AFFECT ITS OBLIGATIONS HEREUNDER.

Section 15. Information. Each Guarantor assumes all responsibility for being and
keeping itself informed of the financial condition of the Borrower and the other Guarantors, and of
all other circumstances bearing upon the risk of nonpayment of any of the Guarantied Obligations
and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and
agrees that none of the Credit Parties shall have any duty whatsoever to advise any Guarantor of
information regarding such circumstances or risks.

Section 16. Governing Law. TO THE FULLEST EXTENT PERMITTED BY LAW, EACH OF THE
PARTIES HERETO HEREBY UNCONDITIONALLY AND IRREVOCABLY WAIVES ANY CLAIM TO ASSERT THAT THE LAW OF
ANY OTHER JURISDICTION GOVERNS THIS GUARANTY. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK PURSUANT TO SECTION 5-1401 OF THE NEW YORK
GENERAL OBLIGATIONS LAW.

Section 17. WAIVER OF JURY TRIAL; ETC.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG ANY
GUARANTOR, THE AGENT OR ANY OTHER CREDIT PARTY WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF
LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT
PERMITTED BY APPLICABLE LAW, EACH OF THE CREDIT PARTIES AND EACH GUARANTOR HEREBY WAIVES ITS RIGHT
TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN
WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT OR BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER
BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OTHER CREDIT PARTY OF ANY KIND OR NATURE. TO THE
EXTENT THAT THE GUARANTOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT
OR FROM ANY LEGAL PROCESS (WHETHER FROM SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT
IN AID OF EXECUTION OF A JUDGMENT, EXECUTION OR OTHERWISE), THE GUARANTOR HEREBY IRREVOCABLY WAIVES
SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS GUARANTY.

(b) EACH OF THE GUARANTORS, THE AGENT AND EACH OTHER CREDIT PARTY HEREBY IRREVOCABLY SUBMITS
TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES
DISTRICT COURT LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK, NEW YORK, AND APPELLATE COURTS FROM
ANY THEREOF TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG ANY GUARANTOR, THE AGENT
OR ANY OTHER CREDIT PARTY, PERTAINING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE LOANS, THE
LETTERS OF CREDIT, THE NOTES OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING HEREFROM OR
THEREFROM. EACH GUARANTOR AND EACH CREDIT PARTY EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS. EACH PARTY FURTHER WAIVES ANY
OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY
SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH AGREES
NOT TO PLEAD OR CLAIM THE SAME. THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED
TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY OTHER CREDIT PARTY OR THE ENFORCEMENT BY
THE AGENT OR ANY OTHER CREDIT PARTY OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE
JURISDICTION.

(c) THE PROVISIONS OF THIS SECTION HAVE BEEN CONSIDERED BY EACH PARTY WITH THE ADVICE OF
COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF, AND SHALL SURVIVE THE
PAYMENT OF THE LOANS AND ALL OTHER AMOUNTS PAYABLE HEREUNDER OR UNDER THE OTHER LOAN DOCUMENTS AND
THE TERMINATION OF THIS GUARANTY.

Section 18. Loan Accounts. Each Credit Party may maintain books and accounts setting
forth the amounts of principal, interest and other sums paid and payable with respect to the
Guarantied Obligations, and in the case of any dispute relating to any of the outstanding amount,
payment or receipt of any of the Guarantied Obligations or otherwise, the entries in such books and
accounts shall be deemed prima facie evidence of the amounts and other matters set forth herein.
The failure of a Credit Party to maintain such books and accounts shall not in any way relieve or
discharge any Guarantor of any of its obligations hereunder.

Section 19. Waiver of Remedies. No delay or failure on the part of a Credit Party in
the exercise of any right or remedy it may have against any Guarantor hereunder or otherwise shall
operate as a waiver thereof, and no single or partial exercise by a Credit Party of any such right
or remedy shall preclude any other or further exercise thereof or the exercise of any other such
right or remedy. The remedies provided in this guaranty are not cumulative.

Section 20. Termination. This Guaranty shall remain in full force and effect until
indefeasible payment in full of the Guarantied Obligations, the cancellation of all Letters of
Credit and the other Obligations and the termination or cancellation of the Credit Agreement in
accordance with its terms.

Section 21. Successors and Assigns. Each reference herein to the Agent or the other
Credit Parties shall be deemed to include such Person’s respective successors and assigns
(including, but not limited to, any holder of the Guarantied Obligations) in whose favor the
provisions of this Guaranty also shall inure, and each reference herein to each Guarantor shall be
deemed to include such Guarantor’s permitted successors and assigns, upon whom this Guaranty also
shall be binding. The Lenders, the Issuing Bank and the Swingline Lender may, in accordance with
the applicable provisions of the Credit Agreement, assign, transfer or sell any Guarantied
Obligation, or grant or sell participations in any Guarantied Obligations, to any Person without
the consent of, or notice to, any Guarantor and without releasing, discharging or modifying any
Guarantor’s obligations hereunder. Each Guarantor hereby consents to the delivery by the Agent or
any Lender to any assignee or Participant (or any prospective assignee or Participant) of any
financial or other information regarding the Borrower or any Guarantor. No Guarantor may assign or
transfer its obligations hereunder to any Person without the prior written consent of all Lenders
and any such assignment or other transfer to which all of the Lenders have not so consented shall
be null and void.

Section 22. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE GUARANTORS
HEREUNDER SHALL BE JOINT AND SEVERAL, AND ACCORDINGLY, EACH GUARANTOR CONFIRMS THAT IT IS LIABLE
FOR THE FULL AMOUNT OF THE “GUARANTIED OBLIGATIONS” AND ALL OF THE OBLIGATIONS AND LIABILITIES OF
EACH OF THE OTHER GUARANTORS HEREUNDER.

the Required Lenders (or all of the Lenders if required under the terms of the Credit Agreement),
the Agent and each Guarantor.

Section 24. Payments. All payments to be made by any Guarantor pursuant to this
Guaranty shall be made in Dollars, in immediately available funds to the Agent, not later than
12:00 p.m. on the date of demand therefore.

Section 25. Expenses. The Guarantor shall reimburse the Agent on demand for all
costs, expenses and charges (including without limitation fees and charges of external legal
counsel for the Agent and costs allocated by its internal legal department) incurred by the Agent
in connection with the preparation, performance or enforcement of this Guaranty. The obligations
of the Guarantor under this Section shall survive the termination of this Guaranty.

Section 26. Notices. All notices, requests and other communications hereunder shall
be in writing (including facsimile transmission or similar writing) and shall be given (a) to each
Guarantor at its address set forth below its signature hereto, (b) to the Agent, any Lender, the
Issuing Bank or the Swingline Lender at its respective address for notices provided for in the
Credit Agreement, or (c) as to each such party at such other address as such party shall designate
in a written notice to the other parties. Each such notice, request or other communication shall
be effective (i) if mailed, when received; (ii) if telecopied, when transmitted; or (iii) if hand
delivered, when delivered; provided, however, that any notice of a change of
address for notices shall not be effective until received.

Section 27. Severability. In case any provision of this Guaranty shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

Section 28. Headings. Section headings used in this Guaranty are for convenience only
and shall not affect the construction of this Guaranty.

Section 29. Limitation of Liability. Neither the Agent, any other Credit Party nor
any affiliate, officer, director, employee, attorney, or agent of such Persons, shall have any
liability with respect to, and each Guarantor hereby waives, releases, and agrees not to sue any of
them upon, any claim for any special, indirect, incidental, or consequential damages suffered or
incurred by a Guarantor in connection with, arising out of, or in any way related to, this Guaranty
or any of the other Loan Documents, or any of the transactions contemplated by this Guaranty, the
Credit Agreement or any of the other Loan Documents. Each Guarantor hereby waives, releases, and
agrees not to sue the Agent, any other Credit Party or any of such Person’s affiliates, officers,
directors, employees, attorneys, or agents for punitive damages in respect of any claim in
connection with, arising out of, or in any way related to, this Guaranty, the Credit Agreement or
any of the other Loan Documents, or any of the transactions contemplated by Credit Agreement or
financed thereby.

Section 30. Integration; Effectiveness. This Guaranty sets forth the entire
understanding of the Guarantor and the Credit Parties relating to the guarantee of the Guaranteed
Obligations and constitutes the entire contract between the parties relating to the subject matter
hereof and supersede any and all previous agreements and understandings, oral or written, relating
to the subject matter hereof. This Guaranty shall become effective when it shall have been
executed and delivered by the Guarantor to the Agent. Delivery of an executed signature page of
this Guaranty by telecopy shall be effective as delivery of a manually executed signature page of
this Guaranty.
