     THIS THIRD AMENDED AND RESTATED CREDIT AGREEMENT is dated as of July 26, 2005 (the “Closing
Date”), among PRENTISS PROPERTIES ACQUISITION PARTNERS, L.P., a Delaware limited partnership
(“Borrower”), each of the lenders that are a signatory hereto (each such lender, together with each
lender that becomes a signatory hereto as provided in Sections 2.5 and 13.11(b), being
individually, together with its successors and assigns, a “Lender” and collectively, the
“Lenders”), JPMORGAN CHASE BANK, N.A., a national banking association successor by merger to Bank
One, N.A., as Administrative Agent (in such capacity, together with its successors and assigns,
“Administrative Agent”), and BANK OF AMERICA, N.A., as Syndication Agent (in such capacity,
together with its successors and assigns, “Syndication Agent”).

R E C I T A L S:

     1. Reference is hereby made to that certain Second Amended and Restated Credit Agreement dated
as of February 19, 2004, executed by Borrower, certain of the Lenders, Administrative Agent, the
Syndication Agent defined therein (as renewed, extended, modified, and amended from time to time,
the “Original Agreement”).

     2. Borrower, Administrative Agent, Syndication Agent, and the Lenders desire to amend, modify,
renew, and restate the Original Agreement in the form of this Agreement to modify certain terms,
conditions, and covenants contained in the Original Agreement.

     3. Upon and subject to the terms and conditions of this Agreement, the parties hereto are
willing to amend and restate the Original Agreement.

     NOW THEREFORE, in consideration of the mutual promises herein contained, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree that the Original Agreement shall be amended and restated as follows:

SECTION 1

DEFINITIONS AND TERMS

     1.1 Definitions. Unless otherwise indicated, as used in the Loan Documents:

     “Adjusted Aggregate EBITDA” means, for any period, (a) Aggregate EBITDA, minus (b) the EBITDA
Adjustments, on a Consolidated Basis, for all Properties.

     “Adjusted Property EBITDA” means, for any Property, the product of (a) the difference between
(i) the EBITDA of such Property, minus (ii) the EBITDA Adjustments for such Property, in each case
for the three (3) month period ending on the last day of the fiscal quarter immediately preceding
such determination date, times (b) four (4). For Properties owned for less than three (3) months
as of the date of determination, EBITDA of all such Properties shall be equal to the lesser of (I)
the product of (x) the Approved Costs of such Properties, times (y) eight percent (8%), and (II)
Borrower’s most-recent asset manager’s forecasts for the EBITDA of such Properties for the first
(1st) calendar quarter following acquisition thereof; provided that if Administrative Agent shall
reasonably determine that such amount is not an appropriate computation of EBITDA of any such
Property, then EBITDA for all such Properties shall be based upon the most recent three (3) month
period available.

     “Administrative Agent” is defined in the preamble.

 

Third Amended and Restated

Credit Agreement

 

     “Affiliate” of a Person means any other individual or entity who directly or indirectly
controls, or is controlled by, or is under common control with, that Person. For purposes of this
definition “control,” “controlled by,” and “under common control with” mean possession, directly or
indirectly, of power to direct (or cause the direction of) management or policies (whether through
ownership of Stock, by contract, or otherwise).

     “Agents” means Administrative Agent and Syndication Agent, and “Agent” means any one of the
Agents.

     “Aggregate EBITDA” means EBITDA of the Companies, for any period, as determined on a
Consolidated Basis.

     “Agreement” means this Credit Agreement, as modified, amended, supplemented, or restated from
time to time.

     “Applicable Amount” means (a) with respect to a Contract Property, the lesser of (i) the
purchase price of such Contract Property (or the Stock of the Person that owns such Contract
Property), and (ii) the maximum personal liability of the Companies to pay such purchase price as
determined by Borrower in a manner reasonably acceptable to Administrative Agent, and (b) with
respect to a Development Property, the unpaid balance of any Liabilities incurred to finance the
costs of constructing or developing such Development Property to the extent that a Company is
obligated (as guarantor or otherwise) with respect to such Liabilities.

     “Applicable Margin” means, at the time of determination thereof:

     (a) for any period in which an Investment Grade Rating does not exist, the interest margin
over the Eurodollar Rate and the Base Rate, as the case may be, shall be based upon the Index Ratio
as follows:

	 	 	 	 	 	 	 	 	 
	 	 	Applicable Margin	 	 	Applicable Margin	 
	 	 	for Eurodollar	 	 	for Base Rate	 
	Index Ratio	 	Borrowings	 	 	Borrowings	 
	Greater than or equal to 0.55 to 1.0
	 	 	1.35	%	 	 	0.	%
	 
	 	 	 	 	 	 
	Less than 0.55 to 1.0 but greater
than or equal to 0.50 to 1.0
	 	 	1.20	%	 	 	0	%
	 
	 	 	 	 	 	 
	Less than 0.50 to 1.0 but greater
than or equal to 0.45 to 1.0
	 	 	1.05	%	 	 	0	%
	 
	 	 	 	 	 	 
	Less than 0.45 to 1.0 but greater
than or equal to 0.35 to 1.0
	 	 	0.95	%	 	 	0	%
	 
	 	 	 	 	 	 
	Less than 0.35 to 1.0
	 	 	0.85	%	 	 	0	%
	 
	 	 	 	 	 	 

     The Index Ratio shall be determined from the Compliance Certificate delivered to
Administrative Agent pursuant to Section 7.1; provided that the initial Applicable Margin shall be
based upon the Compliance Certificate dated as of March 31, 2005. The adjustment, if any, to the
Applicable Margin

2

Third Amended and Restated

Credit Agreement

 

shall be effective commencing on the fifth (5th) Business Day after delivery of such
Compliance Certificate. If Borrower fails at any time to furnish to Administrative Agent the
Compliance Certificate as required to be delivered pursuant to Section 7.1, then the maximum
Applicable Margin shall apply until such time as such Compliance Certificate is so delivered.

     (b) beginning with the period commencing on the date of delivery by Borrower to Administrative
Agent of notice that Borrower achieved an Investment Grade Rating, and continuing until the public
announcement of a downgrade resulting in Borrower no longer having an Investment Grade Rating the
interest margin over the Eurodollar Rate and the Base Rate, as the case may be, and the percentage
facility fee payable pursuant to Section 3.19(d), shall be based upon the Applicable Rating as
follows:

	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	 	 	 	 	 	 	 	 	 	 	 	 	Applicable	 	Applicable

	 	 	Moody’s	 	S & P	 	Agency	 	Base Rate	 	Eurodollar	 	 
	Level	 	Rating	 	Rating	 	Rating	 	Borrowings	 	Borrowings	 	Facility Fee
	1
	 	A3 or higher	 	A- or higher	 	A- or higher	 	 	0.00	%	 	 	0.50	%	 	 	0.15	%
	2
	 	Baa1	 	BBB+	 	BBB+	 	 	0.00	%	 	 	0.525	%	 	 	0.175	%
	3
	 	Baa2	 	BBB	 	BBB	 	 	0.00	%	 	 	0.65	%	 	 	0.20	%
	4
	 	Baa3	 	BBB-	 	BBB-	 	 	0.00	%	 	 	0.80	%	 	 	0.20	%

     The “Applicable Rating” shall be determined as follows: (i) if a Debt Rating is issued by only
two (2) of Moody’s, S & P, and a Third Agency, and (A) such Debt Ratings shall fall within
different Levels (but not more than one (1) Level apart), then the Applicable Rating shall be the
higher of such Debt Ratings (e.g. if the Moody’s Rating is at Level 1 and the S & P Rating is at
Level 2, then the Applicable Rating shall be determined by reference to Level 1), (B) such Debt
Ratings shall fall within different Levels (two (2) or more Levels apart), the Applicable Rating
shall be the Debt Rating at the midpoint between the highest Debt Rating and the lowest Debt Rating
(e.g. if the Moody’s Rating is at Level 1 and the S & P Rating is at Level 3, then the Applicable
Rating shall be determined by reference to Level 2); provided however, that if there is no such
midpoint, then the Applicable Rating shall be determined by reference to the Level which is the
higher Debt Rating of the two intermediate Debt Ratings (e.g., if the S & P Rating is at Level 1
and the Moody’s Rating is at Level 4, then the Applicable Margin shall be determined by reference
to Level 2); and (ii) if a Debt Rating is issued by each of Moody’s, S & P, and a Third Agency,
then the Applicable Rating shall be the lower of the two (2) highest such Debt Ratings (e.g. if the
Moody’s Rating is at Level 1, the S & P Rating is at Level 2, and the Third Agency Rating is at
Level 3, then the Applicable Rating shall be determined by reference to Level 2). Each change in
the Applicable Rating based upon a publicly announced change in the Debt Rating shall be effective
during the period commencing on the date of the public announcement thereof and ending on the date
immediately preceding the effective date of the next such change.

     “Approved Costs” means, for any Property, the sum of the acquisition, construction, and other
capitalized costs of such Property (or the Stock of the Company that owns such Property), whether
in the form of cash, property, liabilities assumed, or other consideration.

assignee (with the consent of any party whose consent is required by Section 13.11), and accepted
by the Agent, in the form of Exhibit E or any other form approved by the Agent.

     “Assumed Interest Expense” means, as of any date, the product of (a) the aggregate amount of
all Unsecured Debt of the Companies as of such date, times (b) the weighted average interest rate
per annum on all such Unsecured Debt as of such date.

     “Base Rate” means, for any day, the greater of (a) the sum of the Federal Funds Rate plus
one-half of one percent (0.5%), and (b) the annual interest rate most recently announced by
Administrative Agent as its prime rate (or, if the Person then acting as Administrative Agent under
this Agreement is not a bank organized under the Governmental Requirements of the United States or
any State, then the rate announced by JPMorgan Chase Bank, N.A., or any successor thereof, as its
prime rate) in effect at its principal office, automatically fluctuating upward and downward with
and as specified in each announcement without special notice to Borrower or any other Person (which
prime rate may not necessarily represent the lowest or best rate actually charged to a customer).

     “Base Rate Borrowing” means a Borrowing bearing interest at the Base Rate plus the Applicable
Margin.

     “Binding Agreement” means a binding agreement pursuant to which a Company has agreed to
purchase a Contract Property or a Development Property from another Person and in which such Person

Contract Property or Development Property and which remedies are not limited to retaining earnest
money, escrow, liquidated damages not to exceed ten percent (10%) of the applicable purchase price,
or other deposits of a Company or similar limitations on the liability of any Company.

     “Borrowing” means (without duplication) any amount disbursed by (a) Lenders to or on behalf of
Borrower under the Loan Documents, or (b) any Lender in accordance with, and to satisfy the
obligations of Borrower under, any Loan Document.

Borrower, or (b) the date any Borrowing is converted hereunder to another Type of Borrowing.

than the Business Day immediately preceding the Termination Date;

19

Third Amended and Restated

Credit Agreement

 

     (b) each Borrowing requested by Borrower must be in an amount not less than $1,000,000 (unless
such Borrowing is to repay a Swing Line Loan or an LC Disbursement) or a greater integral multiple
of $100,000 or, if less, the Unused Commitment;

     (c) the Total Principal Debt plus the LC Exposure may not exceed the Total Commitment; and

     (d) no Lender’s Principal Debt may exceed such Lender’s Commitment.

     2.2 Swing Line Subfacility.

     (a) Subject to the terms and conditions hereof, if necessary to meet Borrower’s funding
deadlines, Administrative Agent agrees to make Swing Line Loans to Borrower at any time on or prior
to the three (3) Business Days prior to the Termination Date, not to exceed an amount at any one
time outstanding equal to the lesser of (i) $50,000,000.00, and (ii) the Unused Commitment. Swing
Line Loans shall constitute “Borrowings” for all purposes hereunder, except that Swing Line Loans
shall not be considered a utilization of any Lender’s Commitment (other than of Administrative
Agent). Swing Line Loans aggregating more than $15,000,000.00 may not be outstanding for more than
fourteen (14) consecutive Business Days.

     (b) Each request for a Swing Line Loan shall be in the amount of $500,000 or a greater
integral multiple of $500,000. Borrower may request a Swing Line Loan by submitting a Notice of
Borrowing to Administrative Agent. Such Notice of Borrowing must be received by Administrative
Agent no later than 12:00 noon on the Borrowing Date for such Swing Line Loan; provided that
Borrower shall have provided telephonic notice to Administrative Agent no later than 11:00 a.m. on
the Borrowing Date for such Swing Line Loan. Administrative Agent shall make such Swing Line Loan
available to Borrower in Houston, Texas at 12:00 noon on such Borrowing Date.

     (c) Upon the occurrence of a Default, Administrative Agent shall, on behalf of Borrower (which
hereby irrevocably directs and authorizes Administrative Agent to act on its behalf), request a
Base Rate Borrowing (unless Borrower has requested a Eurodollar Borrowing in accordance with the
terms of this Agreement) from Lenders (and each Lender shall fund its Pro Rata Share thereof) in an
amount sufficient to repay the Principal Debt outstanding under such Swing Line Loan; provided that
such Borrowing shall be made notwithstanding Borrower’s noncompliance with Section 5. The proceeds
of such Borrowing shall be immediately applied to repay such Swing Line Loan. If such Lender does
not promptly make such Borrowing upon Administrative Agent’s demand therefor, and until such time
as such Lender makes the required payment, Administrative Agent shall be deemed to continue to have
outstanding its ratable portion of the Principal Debt of such Swing Line Loan in the amount of such
unpaid obligation. If, for any reason (including but not limited to the filing of a petition in
bankruptcy with respect to Borrower), a Borrowing may not be (as determined by Administrative Agent
in its sole discretion), or is not, made pursuant to this Section 2.2(c) to repay any Swing Line
Loan as required hereby, then, effective on the date such Borrowing would otherwise have been made,
each Lender severally, unconditionally, and irrevocably agrees that it shall be deemed to have
purchased an undivided participating interest in such Swing Line Loan (an “Unrefunded Swing Line
Borrowing”) to the extent of such Lender’s Pro Rata Share thereof. Each Lender shall fund a
Borrowing or a participation in the Unrefunded Swing Line Borrowings no later than the close of
business on the date notice of such funding requirement is given by Administrative Agent if such
notice was given prior to 11:00 a.m. on any Business Day, or if made at any other time, on the next
Business Day following the date of such notice. All such amounts payable by any Lender under this
Section 2.2(c) shall include interest thereon from the date on which such payment is payable by
such Lender to, but not including, the date such amount is paid

20

Third Amended and Restated

Credit Agreement

 

by such Lender to Administrative Agent, at the Federal Funds Rate. Each payment by Borrower
of all or any part of any Swing Line Loan shall be paid to Administrative Agent for the benefit of
Administrative Agent and those Lenders who hold funded participations in such Swing Line Loan under
this Section 2.2(c); provided that with respect to any such participation, all interest on the
Principal Debt of such Swing Line Loan to which such participation relates accruing prior to the
date of funding such participation, shall be payable solely to Administrative Agent for the account
of Administrative Agent (and all Lenders holding funded participations in any Unrefunded Swing Line
Borrowing prior to such date). Any Lender holding a participation in any Unrefunded Swing Line
Borrowing may exercise any and all Rights of banker’s lien, setoff, or counterclaim with respect to
any and all moneys owing by Borrower to such Lender by reason thereof as fully as if such Lender
had extended such Borrowing directly to Borrower in the amount of such participation. Whenever, at
any time after Administrative Agent has received from any Lender such Lender’s participating
interest in any Swing Line Loan, Administrative Agent receives any payment on account thereof,
Administrative Agent will promptly distribute to such Lender its participating interest in such
amount (appropriately adjusted, in the case of interest payments, to reflect the period of time
during which such Lender’s participating interest was outstanding and funded); provided, however,
that in the event that such payment received by Administrative Agent is required to be returned,
such Lender will return to Administrative Agent any portion thereof previously distributed by
Administrative Agent to it.

     (d) Unless Administrative Agent knew at the time Administrative Agent funded a Swing Line Loan
that Borrower had not satisfied the conditions in this Agreement to obtain a Borrowing, each
Lender’s obligation to either make a Borrowing to refund, or to purchase a participation interest
in, its Pro Rata Share of all Swing Line Loans as provided in Section 2.2(c) shall be absolute and
unconditional and shall not be affected by any circumstance, including, without limitation (i) any
set-off, counterclaim, recoupment, defense, or other right which such Lender or any other Person
may have against Administrative Agent or any other Person for any reason whatsoever, (ii) the
occurrence or continuance of a Potential Default or Default or the termination of any Lender’s
Commitment, (iii) the occurrence of any Material Adverse Event, (iv) any breach of this Agreement
or any other Loan Document by any Company, any Agent, or any other Lender, or (v) any other
circumstance, happening, or event whatsoever, whether or not similar to any of the foregoing. Any
portion of a Swing Line Loan which has not been refunded by a Borrowing may be treated by
Administrative Agent as a Borrowing which was not funded by the non-purchasing Lenders as
contemplated in Section 2.2(c) of this Agreement, and as a funding by Administrative Agent under
the Total Commitment in excess of Administrative Agent’s Commitment. Each Swing Line Loan refunded
by a Borrowing shall cease to be a Swing Line Loan for the purposes of this Agreement but shall be
a Borrowing made under the Total Commitment and each Lender’s Commitment.

     2.3 Borrowing Procedure. The following procedures apply to Borrowings (other than Swing Line
Loans):

     (a) Borrower may request a Borrowing by submitting to Administrative Agent a Borrowing
Request. The Borrowing Request must be received by Administrative Agent no later than 11:00 a.m.
on (i) the third (3rd) Business Day preceding the Borrowing Date for any Eurodollar Borrowing, or
(ii) the Business Day preceding the Borrowing Date for any Base Rate Borrowing. Administrative
Agent shall promptly notify each Lender of its receipt of any Borrowing Request and its contents.
A Borrowing Request is irrevocable and binding on Borrower.

     (b) By 11:00 a.m. on the applicable Borrowing Date, each Lender shall remit its Pro Rata Share
of each requested Borrowing by wire transfer to Administrative Agent pursuant to Administrative
Agent’s wire transfer instructions on Schedule 1 (or as otherwise directed by Administrative Agent) in

21

Third Amended and Restated

Credit Agreement

 

funds that are available for immediate use by Administrative Agent. Subject to receipt of
such funds, Administrative Agent shall make such funds available to Borrower in Houston, Texas at
12:00 noon on such Borrowing Date (unless it has actual knowledge that any applicable condition
precedent has not been satisfied by Borrower).

     (c) Absent contrary written notice from a Lender, Administrative Agent may assume that each
Lender has made its Pro Rata Share of the requested Borrowing available to Administrative Agent on
the applicable Borrowing Date, and Administrative Agent may, in reliance upon such assumption (but
is not required to), make available to Borrower a corresponding amount. If a Lender fails to make
its Pro Rata Share of any requested Borrowing available to Administrative Agent on the applicable
Borrowing Date, then Administrative Agent may recover the applicable amount on demand (i) from such
Lender, together with interest at the Federal Funds Rate for the period commencing on the date the
amount was made available to Borrower by Administrative Agent and ending on (but excluding) the
date Administrative Agent recovers the amount from such Lender, or (ii) if such Lender fails to pay
its amount upon Administrative Agent’s demand, then from Borrower, together with interest at an
annual interest rate equal to the rate applicable to the requested Borrowing for the period
commencing on the Borrowing Date and ending on (but excluding) the date Administrative Agent
recovers the amount from Borrower. No Lender is responsible for the failure of any other Lender to
make its Pro Rata Share of any Borrowing.

     2.4 Termination. Without premium or penalty, and upon giving at least three (3) Business Days
prior written and irrevocable notice to Administrative Agent, Borrower may terminate all or part of
the unused portion of the Total Commitment. Each partial termination must be in an amount of not
less than $10,000,000 or a greater integral multiple thereof, and shall be Pro Rata among all

     (b) Prior to January 26, 2008, Administrative Agent may, from time to time, but no more than
three (3) times prior to such date, at the request of Borrower, increase the Total Commitment by
(i) admitting additional Lenders hereunder (each a “Subsequent Lender”), or (ii) increasing the
Commitment of any Lender (each an “Increasing Lender”), subject to the following conditions:

     (i) Each Subsequent Lender is an Eligible Assignee;

     (ii) Borrower executes (A) a new Note payable to the order of a Subsequent Lender, or
(B) a replacement Note payable to the order of an Increasing Lender;

     (iii) Each Subsequent Lender executes a signature page to this Agreement;

     (iv) After giving effect to the admission of any Subsequent Lender or the increase in
the Commitment of any Increasing Lender, the aggregate of the Total Commitment does not
exceed $500,000,000 unless all Lenders consent in writing;

     (v) Each increase in the Total Commitment shall be in the minimum amount of
$10,000,000 or a greater integral multiple of $1,000,000;

     (vi) No admission of any Subsequent Lender shall increase the Commitment of any
existing Lender without the consent of such Lender;

22

Third Amended and Restated

Credit Agreement

 

     (vii) No Lender shall be an Increasing Lender without the written consent of such
Lender;

     (viii) Such increase shall have been approved by Administrative Agent, such consent
not to be unreasonably withheld, conditioned, or delayed; and

     (ix) No Potential Default or Default exists.

     Subject to the conditions precedent set forth above, Administrative Agent agrees to exercise
ordinary and reasonable diligence to complete documentation to admit a Subsequent Lender or
increase the Commitment of an Increasing Lender. After the admission of any Subsequent Lender or
the increase in the Commitment of any Increasing Lender, Administrative Agent shall promptly
provide to each Lender a new Schedule 1 to this Agreement.

     2.6 Extension of Maturity Date.

     (a) Borrower may request that the Initial Termination Date be extended to the Extended
Termination Date by submitting to Administrative Agent a written request (an “Extension Request”)
not earlier than ninety (90) days prior to, nor later than thirty (30) days prior to, the Initial
Termination Date.

     (b) The Initial Termination Date shall be automatically extended to the Extended Termination
Date if, at the time of Administrative Agent’s receipt of the Extension Request, (i) no Potential
Default or Default exists or would result from such extension, both at the date of the Extension
Request and upon the Initial Termination Date, and (ii) Borrower shall have paid to Administrative
Agent for the Pro Rata benefit of each Lender an extension fee in an amount equal to fifteen one
hundredths of one percent (0.15%) times such Lender’s Commitment.

     2.7 Letters of Credit

     (a) General. Subject to the terms and conditions set forth herein, the Borrower may request
the issuance of Letters of Credit in U.S. Dollars 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
prior to the Termination Date. 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,

23

Third Amended and Restated

Credit Agreement

 

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 $25,000,000.00 and (ii) the sum of the Total Principal Debt plus the LC
Exposure shall not exceed the Total Commitment.

     (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 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 Termination 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 Pro Rata
Share 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 Pro Rata Share
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 12:00 noon 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. 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 12:00 noon on (i) the Business Day that the Borrower
receives such notice, if such notice is received prior to 10:00 a.m. 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 notwithstanding the
foregoing the Borrower may, subject to the conditions to borrowing set forth herein, request on the
same date that Borrower receives notice of such LC Disbursement, in accordance with this Agreement
that such payment be financed with a Base Rate 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 Base Rate 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 Pro Rata
Share thereof. Promptly following receipt of such notice, each Lender shall pay to the
Administrative Agent its Pro Rata Share of the payment then due from the Borrower, in the same
manner as provided in Section 2.3 with respect to Loans made by such Lender (and Section 2.3 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

24

Third Amended and Restated

Credit Agreement

 

funding of Base Rate Borrowing or a Swingline Loan as contemplated above) shall not constitute
a Borrowing 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) except as provided below,
payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other
document that does not comply with the terms of such Letter of Credit, 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 Base Rate Borrowings; provided that, if the Borrower fails
to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then the
Default Rate shall apply. Interest accrued pursuant to this paragraph shall be for the account of
the Issuing Bank, except that

25

Third Amended and Restated

Credit Agreement

 

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 3.19(e). 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 Default shall occur and be continuing, on the Business Day
that the Borrower receives notice from the Administrative Agent 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 Default with respect to the Borrower described in
Section 10.3. 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, 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 a Default, such amount (to the extent not applied as aforesaid) shall
be returned to the Borrower within three Business Days after all Defaults have been cured or
waived.

SECTION 3

TERMS OF PAYMENT

     3.1 Notes and Payments.

     (a) The Total Principal Debt (other than under the Swing Line Subfacility) shall be evidenced
by the Notes, which Notes shall be payable to Lenders in the aggregate stated principal amount of
the Total Commitment. The Principal Debt under the Swing Line Subfacility shall be evidenced by
the Swing Line Note.

26

Third Amended and Restated

Credit Agreement

 

     (b) Borrower must make each payment and prepayment on the Obligation, without offset,
counterclaim, or deduction, to Administrative Agent’s principal office in Houston, Texas, in funds
that will be available for immediate use by Administrative Agent by 12:00 noon on the day due.
Payments received after such time shall be deemed received on the next Business Day.
Administrative Agent shall pay to each Lender any payment to which such Lender is entitled on the
same day Administrative Agent receives the funds from Borrower if Administrative Agent receives the
payment or prepayment before 12:00 noon, and otherwise before 12:00 noon on the following Business
Day. If and to the extent that Administrative Agent does not make payments to Lenders when due,
then Administrative Agent shall be obligated to pay to Lenders such unpaid amounts together with
interest at the Federal Funds Rate from the due date until (but not including) the payment date.

     3.2 Interest and Principal Payments.

     (a) Interest Payments. Accrued interest on each Borrowing is due and payable on the first
(1st) day of each calendar month during the term of this Agreement, commencing on August 1, 2005,
and on the Termination Date. (b) Principal Payments. The Total Principal Debt (other than under
the Swing Line Subfacility and each unreimbursed LC Disbursement) is due and payable on the
Termination Date. The Principal Debt under the Swing Line Subfacility shall be due and payable as
provided in Section 2.2 and on the Termination Date.(c) Voluntary Prepayment. Borrower may
voluntarily repay or prepay all or any part of the Total Principal Debt at any time without premium
or penalty, subject to the following conditions:

     (i) Administrative Agent must receive Borrower’s written payment notice by 11:00 a.m.
on (A) the Business Day preceding the date of payment of a Eurodollar Borrowing, and (B)
the Business Day preceding the date of payment of a Base Rate Borrowing, which shall
specify the payment date and the Type and amount of the Borrowing(s) to be paid, and which
shall constitute an irrevocable and binding obligation of Borrower to make a repayment or
prepayment on the designated date;

     (ii) each partial repayment or prepayment must be in a minimum amount of at least
$1,000,000 (except for repayments or prepayments of Swing Line Loans) or a greater integral
multiple of $100,000, or, if less, the Total Principal Debt; and

     (iii) Borrower shall pay any related Funding Loss upon demand.

     3.3 Interest Options. Except as specifically otherwise provided, Borrowings (other than Swing
Line Loans) shall bear interest at an annual rate equal to the lesser of (a) the Base Rate plus the
Applicable Margin, or the Eurodollar Rate plus the Applicable Margin (in each case as designated or
deemed designated by Borrower and, in the case of Eurodollar Borrowings, for the Interest Period
designated by Borrower), and (b) the Maximum Rate. Except as specifically otherwise provided,
Swing Line Loans shall bear interest at an annual rate equal to the lesser of (A) the Swing Line
Rate, and (B) the Maximum Rate. Each change in the Base Rate and Maximum Rate is effective,
without notice to Borrower or any other Person, upon the effective date of change.

     3.4 Quotation of Rates. A Representative of Borrower may call Administrative Agent before
delivering a Borrowing Request to receive an indication of the interest rates then in effect, but
the indicated rates do not bind Administrative Agent or Lenders or affect the interest rate that is
actually in effect when Borrower delivers its Borrowing Request or on the Borrowing Date.

27

Third Amended and Restated

Credit Agreement

 

     3.5 Default Rate. At the option of the Required Lenders at any time while a Default exists
and to the extent permitted by applicable law, all Principal Debt and unreimbursed LC Disbursements
and accrued interest thereon, and fees and expenses payable hereunder and under the other Loan
Documents shall bear interest at the Default Rate until paid, regardless of whether such payment is
made before or after entry of a judgment.

     3.6 Interest Recapture. If the designated interest rate applicable to any Borrowing exceeds
the Maximum Rate, then the interest rate on that Borrowing is limited to the Maximum Rate, provided
that any subsequent reductions in the designated rate shall not reduce the interest rate thereon
below the Maximum Rate until the total amount of accrued interest equals the amount of interest
that would have accrued if the designated rate had always been in effect. If at maturity (stated
or by acceleration), or at final payment of the Notes, the total interest paid or accrued is less
than the interest that would have accrued if the designated rates had always been in effect, then,
at that time and to the extent permitted by applicable law, Borrower shall pay an amount equal to
the difference between (a) the lesser of the amount of interest that would have accrued if the
designated rates had always been in effect and the amount of interest that would have accrued if
the Maximum Rate had always been in effect, and (b) the amount of interest actually paid or accrued
on the Notes.

     3.7 Interest Calculations.

     (a) Interest shall be calculated on the basis of actual number of days elapsed (including the
first day but excluding the last day) but computed as if each calendar year consisted of (i) 365 or
366 days, as the case may be, for Base Rate Borrowings, and (ii) 360 days for all other Borrowings
(unless the calculation would result in an interest rate greater than the Maximum Rate, in which
event interest shall be calculated on the basis of a year of 365 or 366 days, as the case may be).
All interest rate determinations and calculations by Administrative Agent are conclusive and
binding absent manifest error.

     (b) The provisions of this Agreement relating to calculation of the Base Rate and the
Eurodollar Rate are included only for the purpose of determining the rate of interest or other
amounts to be paid under this Agreement that are based upon those rates. Each Lender may fund and
maintain its funding of all or any part of each Borrowing as it selects.

     3.8 Maximum Rate. Regardless of any provision contained in any Loan Document or any document
related thereto, it is the intent of the parties to this Agreement that no Credit Party may
contract for, charge, take, reserve, receive or apply, as interest on all or any part of the
Obligation any amount in excess of the Maximum Rate or the Maximum Amount or receive any unearned
interest in violation of any applicable law, and, if any Credit Party ever does so, then any excess
shall be treated as a partial repayment or prepayment of principal and any remaining excess shall
be refunded to Borrower. In determining if the interest paid or payable exceeds the Maximum Rate,
Borrower, and the Credit Parties shall, to the maximum extent permitted under applicable law, (a)
treat all Borrowings as but a single extension of credit (and Lenders and Borrower agree that this
is the case and that provision in this Agreement for multiple Borrowings is for convenience only),
(b) characterize any non-principal payment as an expense, fee or premium rather than as interest,
(c) exclude voluntary repayments or prepayments and their effects, and (d) amortize, prorate,
allocate and spread the total amount of interest throughout the entire contemplated term of the
Obligation so that the interest rate does not exceed the Maximum Rate. If, however, the Obligation
is paid in full before the end of its full contemplated term, and if the interest received for its
actual period of existence exceeds the Maximum Amount, then Lenders shall refund any excess (and
Lenders may not, to the extent permitted by applicable law, be subject to any penalties provided by
any Governmental Requirements for contracting for, charging, taking, reserving or receiving

28

Third Amended and Restated

Credit Agreement

 

interest in excess of the Maximum Amount). If the Governmental Requirements of the State of
Texas are applicable for purposes of determining the “Maximum Rate” or the “Maximum Amount,” then
those terms mean the “weekly ceiling” from time to time in effect under Texas Finance Code § 303,
as amended. Borrower agrees that Chapter 346 of the Texas Finance Code, as amended (which regulates
certain revolving credit loan accounts and revolving tri-party accounts), does not apply to the
Obligation.

     3.9 Interest Periods. When Borrower requests any Eurodollar Borrowing, Borrower may elect the
applicable interest period (each an “Interest Period”), which may be, at Borrower’s option, seven
(7) days or one (1), two (2), three (3) or six (6) months, subject to the following conditions:
(a) the initial Interest Period for a Eurodollar Borrowing commences on the applicable Borrowing
Date or conversion date, and each subsequent Interest Period applicable to any Borrowing commences
on the day when the next preceding applicable Interest Period expires; (b) if any Interest Period
for a Eurodollar Borrowing begins on a day for which there exists no numerically corresponding
Business Day in the calendar month at the end of the Interest Period (“Ending Calendar Month”),
then the Interest Period ends on the next succeeding Business Day of the Ending Calendar Month,
unless there is no succeeding Business Day in the Ending Calendar Month in which case the Interest
Period ends on the next preceding Business Day of the Ending Calendar Month; (c) no Interest Period
for any portion of Principal Debt may extend beyond the scheduled repayment date for that portion
of Principal Debt; (d) there may not be in effect at any one time more than eight (8) Interest
Periods; and (e) only one (1) Interest Period of less than one (1) month shall be available at any
time and only if Administrative Agent determines that such Interest Period is available from all
Lenders. When Borrower requests any Swing Line Loan, Borrower shall elect (x) the applicable
interest period (each a “Swing Line Interest Period”) which may be, at Borrower’s option, up to
fourteen (14) days, and (y) if such Swing Line Interest Period is for seven (7) days or more, then
the applicable Swing Line Rate.

     3.10 Conversions and Continuations. Borrower may (a) on the last day of the applicable
Interest Period (or at any other time, subject to payment of any Funding Loss) convert all or part
of a Eurodollar Borrowing to a Base Rate Borrowing, (b) at any time convert all or part of a Base
Rate Borrowing to a Eurodollar Borrowing, and (c) on the last day of an Interest Period, elect a
new Interest Period for a Eurodollar Borrowing; provided that no conversions to or elections of new
Interest Periods for any Eurodollar Borrowings shall be permitted while a Default exists unless the
Required Lenders otherwise consent in writing. Any such conversion is subject to the dollar limits
and denominations of Section 2.1 and may be accomplished by delivering a Borrowing Request to
Administrative Agent no later than 11:00 a.m. (i) on the third (3rd) Business Day before (A) the
conversion date for conversion to a Eurodollar Borrowing, and (B) the last day of the Interest
Period, for the election of a new Interest Period, and (ii) one (1) Business Day before the last
day of the Interest Period for conversion to a Base Rate Borrowing. Administrative Agent shall
notify each Lender of such continuation or conversion. Absent Borrower’s notice of conversion or
election of a new Interest Period, a Eurodollar Borrowing shall be converted to a Base Rate
Borrowing when the applicable Interest Period expires.

     3.11 Order of Application.

     (a) No Default. If no Default exists, then except as otherwise specifically provided in the
Loan Documents, any payment shall be applied to the Obligation in the order and manner as Borrower
directs.

     (b) Default. If a Default exists, any payment (including proceeds from the exercise of any
Rights) shall be applied in the following order: (i) to all fees and expenses for which any Credit
Party have not been paid or reimbursed in accordance with the Loan Documents (and if such payment
is less than all unpaid or unreimbursed fees and expenses, then the payment shall be paid against
unpaid and

29

Third Amended and Restated

Credit Agreement

 

unreimbursed fees and expenses in the order of incurrence or due date); (ii) to accrued
interest on the Principal Debt; (iii) to the Principal Debt of any Swing Line Loans; (iv) to any
unreimbursed LC Disbursements; and (v) to the remaining Obligation in the order and manner as the
Required Lenders deem appropriate.

     (c) Pro Rata. Each payment or prepayment shall be distributed to each Lender in accordance
with its Pro Rata Share of such payment or prepayment.

     3.12 Sharing of Payments, Etc. If any Lender obtains any amount (whether voluntary,
involuntary or otherwise) that exceeds the part of that payment that such Lender is then entitled
to receive under the Loan Documents, then such Lender shall purchase from the other Lenders
participations that will cause the purchasing Lender to share the excess amount ratably with each
other Lender. If all or any portion of any excess amount is subsequently recovered from the
purchasing Lender, then the purchase shall be rescinded and the purchase price restored to the
extent of the recovery. Borrower agrees that any Lender purchasing a participation from another
Lender under this Section may, to the fullest extent permitted by applicable law, exercise all of
its Rights of payment with respect to that participation as fully as if such Lender were the direct
creditor of Borrower in the amount of that participation.

     3.13 Booking Borrowings. To the extent permitted by applicable law, any Lender may make,
carry or transfer its Borrowings at, to, or for the account of any of its branch offices or the
office of any of its Affiliates. However, no Affiliate is entitled to receive any greater payment
under Section 3.15 than the transferor Lender would have been entitled to receive with respect to
those Borrowings, and a transfer may not be made if, as a direct result of it, Section 3.15 or 3.16
would apply to any of the Obligation. If any of the conditions of Sections 3.15 or 3.16 ever apply
to a Lender, then such Lender shall, to the extent possible, carry or transfer its Borrowings at,
to, or for the account of any of its branch offices or the office or branch of any of its
Affiliates so long as the transfer is consistent with the other provisions of this Section, does
not create any burden or adverse circumstance for such Lender that would not otherwise exist, and
eliminates or ameliorates the conditions of Sections 3.15 or 3.16 as applicable.

     3.14 Basis Unavailable or Inadequate for the Eurodollar Rate.

     (a) Determination By Administrative Agent. If Administrative Agent determines that, for any
Eurodollar Borrowing, the basis for determining the applicable rate is not available, then
Administrative Agent shall promptly notify Borrower and Lenders of that determination (which is
conclusive and binding on Borrower absent manifest error), and all Borrowings shall bear interest
at the Base Rate plus the Applicable Margin. Until Administrative Agent notifies Borrower that
such circumstances no longer exist, Lenders’ commitments under this Agreement to make, or to
convert to, Eurodollar Borrowings shall be suspended.

     (b) Determination by a Lender. If any Lender determines that, for any Eurodollar Borrowing
and for other similar loans made by such Lender to similar borrowers, the resulting rate does not
accurately reflect the cost to such Lender of making or converting Borrowings at that rate for the
applicable Interest Period, then such Lender shall promptly notify Administrative Agent and
Borrower, and all Borrowings of such Lender shall bear interest at the Base Rate plus the
Applicable Margin. Until Administrative Agent notifies Borrower that such circumstances no longer
exist, such Lender’s commitment under this Agreement to make, or to convert to, Eurodollar
Borrowings shall be suspended.

     3.15 Additional Costs.

     (a) Eurocurrency Reserves. If, after the date hereof, any Lender shall be required under any
Reserve Requirement to maintain reserves, then (i) such Lender (through Administrative Agent)
shall, within sixty (60) days after the end of any Interest Period with respect to any Eurodollar
Borrowing during which Lender was so required to maintain reserves, deliver to Borrower a
certificate stating (A) that such Lender was required to maintain reserves and as a result such
Lender incurred additional costs in connection with making Eurodollar Borrowings and (B) in
reasonable detail, such Lender’s computations of the amount of additional interest payable by
Borrower, pursuant to the provisions below, and (ii) Borrower shall, promptly upon receipt of any
such certificate, pay to Administrative Agent, for the account to such Lender, additional interest
on the unpaid principal amount of each Eurodollar Borrowing of such Lender made to it outstanding
during the Interest Period with respect to which the above-referenced certificate was delivered to
Administrative Agent, at a rate per annum equal to the difference obtained by subtracting (x) the
Eurodollar Rate for such Interest Period from (y) the rate obtained by dividing such Eurodollar
Rate by a percentage equal to 100% minus the Reserve Requirement of such Lender for such Interest
Period. The amount of interest payable by Borrower to any Lender as stated in any certificate
delivered to Administrative Agent pursuant to the provisions of this Section 3.15(a) shall be
conclusive and binding for all purposes, absent manifest error. The provisions of this Section
3.15(a) shall survive the termination of this Agreement.

     (b) Reserves. With respect to any Eurodollar Borrowing, if (i) any change in present
Governmental Requirement, any change in the interpretation or application of any present
Governmental Requirement, or any future Governmental Requirement imposes, modifies, or deems
applicable (or if compliance by any Lender with any such requirement of any Governmental Authority
results in) any such requirement that any reserves (including any marginal, emergency, supplemental
or special reserves) be maintained, and (ii) those reserves reduce any sums receivable by such
Lender under this Agreement or increase the costs incurred by such Lender in advancing or
maintaining any portion of any Eurodollar Borrowing, then (unless the effect is already reflected
in the rate of interest then applicable under this Agreement) such Lender (through Administrative
Agent) shall deliver to Borrower a certificate setting forth in reasonable detail the calculation
of the amount necessary to compensate it for its reduction or increase (which certificate is
conclusive and binding absent manifest error), and Borrower shall promptly pay that amount to such
Lender upon demand.

     (c) Capital Adequacy. With respect to any Borrowing and for similar loans to similar
borrowers, if any change in present Governmental Requirement or any future Governmental Requirement
regarding capital adequacy or compliance by Administrative Agent or any Lender (or any Person
controlling such Lender) with any request, directive or requirement now existing or hereafter
imposed by any Governmental Authority regarding capital adequacy, or any change in its written
policies or in the risk category of this transaction, reduces the rate of return on its capital as
a consequence of its obligations under this Agreement to a level below that which it otherwise
could have achieved (taking into consideration its policies with respect to capital adequacy) by an
amount deemed by it to be material (and it may, in determining the amount, use reasonable
assumptions and allocations of costs and expenses and use any reasonable averaging or attribution
method), then (unless the effect is already reflected in the rate of interest then applicable under
this Agreement) Administrative Agent or such Lender (through Administrative Agent) shall notify
Borrower and deliver to Borrower a certificate setting forth in reasonable detail the calculation
of the amount necessary to compensate it (which certificate is conclusive and binding absent
manifest error), and Borrower shall promptly pay that amount to Administrative Agent or such Lender
upon demand.

     (d) Taxes. Any Taxes payable by Administrative Agent or any Lender or ruled (by a
Governmental Authority) payable by Administrative Agent or any Lender in respect of this Agreement
or any other Loan Document shall, if permitted by Governmental Requirement, be paid by Borrower,
together with interest and penalties, if any (except for Taxes imposed on or measured by the
overall net income of Administrative Agent or such Lender). Administrative Agent or such Lender
(through Administrative Agent) shall notify Borrower and deliver to Borrower a certificate setting
forth in reasonable detail the calculation of the amount of payable Taxes, which certificate is
conclusive and binding (absent manifest error), and Borrower shall promptly pay that amount to
Administrative Agent for its account or the account of such Lender, as the case may be. If
Administrative Agent or such Lender subsequently receives a refund of the Taxes paid to it by
Borrower, then the recipient shall promptly pay the refund to Borrower.

     (e) Survival. The provisions of this Section 3.15 shall survive the satisfaction and payment
of the Obligation and termination of this Agreement.

     3.16 Change in Governmental Requirement. If any Governmental Requirement makes it unlawful
for any Lender to make or maintain Eurodollar Borrowings, then such Lender shall promptly notify
Borrower and Administrative Agent, and (a) as to undisbursed funds, that requested Borrowing shall
be made as a Base Rate Borrowing, and (b), as to any outstanding Borrowing, (i) if maintaining the
Borrowing until the last day of the applicable Interest Period is unlawful, the Borrowing shall be
converted to a Base Rate Borrowing as of the date of notice, and Borrower shall pay any related
Funding Loss, or (ii) if not prohibited by all Governmental Requirements, the Borrowing shall be
converted to a Base Rate Borrowing as of the last day of the applicable Interest Period, or (iii)
if any conversion will not resolve the unlawfulness, Borrower shall promptly prepay the Borrowing,
without penalty, together with any related Funding Loss.

     3.17 Funding Loss. BORROWER AGREES TO INDEMNIFY EACH LENDER AGAINST, AND PAY TO IT UPON
DEMAND, ANY FUNDING LOSS OF SUCH LENDER. When any Lender demands that Borrower pay any
Funding Loss, such Lender shall deliver to Borrower and Administrative Agent a certificate setting
forth in reasonable detail the basis for incurring Funding Loss and the calculation of the amount,
which calculation is conclusive and binding absent manifest error. The provisions of this Section
3.17 shall survive the satisfaction and payment of the Obligation and termination of this
Agreement.

     3.18 Foreign Lenders. Each Lender that is organized under the Governmental Requirements of
any jurisdiction other than the United States of America or any State thereof (a) represents to
Administrative Agent and Borrower that (i) no Taxes are required to be withheld by Administrative
Agent or Borrower with respect to any payments to be made to it in respect of the Obligation, and
(ii) it has furnished to Administrative Agent and Borrower two (2) duly completed copies of U.S.
Internal Revenue Service Form W-8 BEN, Form W-8 ECI, Form W-8, or any other tax form acceptable to
Administrative Agent (wherein it claims entitlement to complete exemption from U.S. federal
withholding tax on all interest payments under the Loan Documents), and (b) covenants to (i)
provide Administrative Agent and Borrower a new tax form upon the expiration or obsolescence of any
previously delivered form according to Governmental Requirement, duly executed and completed by it,
and (ii) comply from time to time with all Governmental Requirements with regard to the withholding
tax exemption. If any of the foregoing is not true or the applicable forms are not provided and
such party is obligated by law to withhold, then Borrower or Administrative Agent (without
duplication) may deduct and withhold from interest payments under the Loan Documents United States
federal income tax at the full rate applicable under the Code.

     3.19 Fees.

     (a) Treatment of Fees. The fees described in this Section (i) are not compensation for the
use, detention, or forbearance of money, (ii) are in addition to, and not in lieu of, interest and
expenses otherwise described in this Agreement, (iii) are payable in accordance with Section
3.1(b), (iv) are non-refundable, (v) to the fullest extent permitted by applicable law, bear
interest, if not paid when due, at the Default Rate, and (vi) are calculated on the basis of actual
number of days (including the first day but excluding the last day) elapsed, but computed as if
each calendar year consisted of 360 days, unless computation would result in an interest rate in
excess of the Maximum Rate in which event the computation is made on the basis of a year of 365 or
366 days, as the case may be. The fees described in this Section 3.19 are in all events subject to
the provisions of Section 3.8.

     (b) Agent Fees. Borrower shall pay to each Agent, solely for their own accounts, the fees
described in the letter agreement(s) between Borrower and Agents dated the same date as this
Agreement, as such letter agreement(s) may be modified or amended from time to time.

     (c) Commitment Fees.

     (i) Borrower shall pay to Administrative Agent, for the account of Lenders, the
commitment fees described in the letter agreement(s) between Borrower and Agents.

     (ii) Within five (5) days after Administrative Agent sends Borrower notice of the
amount thereof, Borrower agrees to pay to Administrative Agent, for the ratable account of
Lenders, a quarterly unused fee equal to the product of (A) the average Unused Commitment
for each quarter during the term hereof, times (B) the applicable rate per annum set forth
opposite the average Commitment Usage below:

	 	 	 	 	 
	Average Commitment Usage	 	Applicable Percentage Per Annum
	Less than the Total Commitment times 33-1/3%

	 	 	0.20	%
	 

	 	 	 	 
	Equal to or greater than the Total
Commitment times 33-1/3%

	 	 	0.15	%
	 

	 	 	 	 

Such commitment fee shall be due and payable quarterly in arrears for each fiscal quarter
ending on March, June, September, and December during the term hereof for any period in
which the Facility Fee (defined below) is not in effect, commencing with the quarter ending
on September 30, 2005, based upon average Unused Commitment during the applicable quarter.
Solely for purposes of this Section 3.19(c)(ii), “ratable” means, for any calculation
period, with respect to any Lender, the proportion that (A) the average Unused Commitment of
such Lender during the period bears to (B) the aggregate amount of the average Unused
Commitment during the period.

     (d) Facility Fee. For any period in which Borrower has achieved an Investment Grade Rating,
Borrower shall pay to Administrative Agent for the account of each Lender in accordance with its
Pro Rata Share, a facility fee equal to the (a) applicable facility fee as set forth in the
definition of Applicable Margin times (b) the actual daily amount of the Total Commitment,
regardless of usage (the “Facility Fee”). The Facility Fee shall be due and payable quarterly in
arrears on the last Business Day of each March, June, September and December, commencing with the
first such date to occur after the

33

Third Amended and Restated

first date on which the Applicable Margin is determined by reference to the Applicable Rating,
and on the Maturity Date (and, if applicable, thereafter on demand). The Facility Fee shall be
calculated quarterly in arrears, and if there is any change in the Applicable Rating during any
quarter, the actual daily amount shall be computed and multiplied by the Applicable Rating
separately for each period during such quarter that such Applicable Rating was in effect.

     (e) Letter of Credit Fee. 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 Margin used to determine the interest rate applicable to
Eurodollar Borrowings then available to Borrower on the average daily amount of such Lender’s LC
Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the
period from and including the Closing 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,
which may be increased to such Applicable Margin plus four percent (4%) at the option of the
Required Lenders at any time while a Default exists, and (ii) to the Issuing Bank a fronting fee,
which shall accrue at the rate of .125% per annum on the average daily amount of the LC Exposure
(excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period
from and including the Closing 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 (not to be less than $1,500
per Letter of Credit), as well as the Issuing Bank’s standard fees other than issuance 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).

     3.20 Option to Replace Lenders. If any Lender shall make demand for payment or reimbursement
pursuant to Section 3.14(b) or Sections 3.15(a), (b), (c), or (d) or notifies Borrower of the
occurrence of the circumstances described in Section 3.16, then, provided that (a) no Default has
occurred and is continuing, and (b) the circumstances resulting in such demand for payment or
reimbursement are not applicable to all Lenders, Borrower may terminate the Commitment of such
Lender, in whole but not in part, by either (i) (A) giving such Lender and Administrative Agent not
less than five (5) Business Days’ written notice thereof, which notice shall be irrevocable and
effective only upon receipt thereof by such Lender and Administrative Agent and shall specify the
date of such termination, and (B) paying such Lender (and there shall become due and payable) on
such date the outstanding Principal Debt of all Borrowings made by such Lender, all interest
thereon, and any other Obligation owed to such Lender (including any amounts payable under Section
3.17), if any, or (ii) pursuant to the provisions of Section 13.11, proposing the introduction of a
replacement Lender satisfactory to Administrative Agent, or obtaining the agreement of one or more
existing Lenders, to assume the entire amount of the Commitment of the Lender whose Commitment is
being terminated, on the effective date of such termination. Upon the satisfaction of all the
foregoing conditions, such Lender that is being terminated shall cease to be a “Lender” for
purposes of this Agreement, provided that Borrower shall continue to be obligated to such Lender
under Section 7.12 with respect to Indemnified Liabilities (as defined in Section 7.12) arising
prior to such termination.

     4.2 Negative Pledge Agreements. Borrower shall not, and shall not permit any other Company
to, enter into or permit to exist any arrangement or agreement (other than the Loan Documents) that
directly or indirectly prohibits any Company from (a) creating or incurring any Lien (other than
Permitted Liens) on any Unencumbered Property, or (b) transferring ownership of any Unencumbered
Property.

     4.3 Guaranties.

     (a) PPT Guaranty. Pursuant to the PPT Guaranty, PPT shall unconditionally guarantee in favor
of the Credit Parties the full payment and performance of the Obligation.

     (b) Subsidiary Guaranty. Pursuant to the Subsidiary Guaranty or an addendum thereto in the

unconditionally guarantee in favor of the Credit Parties the full payment and performance of the
Obligation subject to Section 4.3(c) below.

     (c) Release of Specific Subsidiary Guarantors. If, as of any date, any Property owned by a
Subsidiary Guarantor is no longer an Unencumbered Property, then Administrative Agent shall, upon
the written request of Borrower, release such Subsidiary Guarantor from the Subsidiary Guaranty
pursuant to a release of guaranty in the form attached to the Subsidiary Guaranty, unless a Default
exists or would result from such release.

indirectly, at least ninety-five percent (95%) of the issued and outstanding Stock of such
Consolidated Affiliate free and clear of any Liens (other than Permitted Liens) or other
restrictions on the sale or pledge thereof, (b) a majority of the holders of the Stock of such
Consolidated Affiliate has the power to cause such Consolidated Affiliate to execute the Subsidiary
Guaranty, grant Liens in the Unencumbered Properties owned by such Consolidated Affiliate, and
transfer ownership of the Unencumbered Properties owned by such Consolidated Affiliate, (c) such

Liabilities, other than (A) the Obligation, (B) trade payables created in the ordinary course of
business, (C) endorsements of negotiable instruments in the ordinary course of business, (D)
contingent Liabilities covered by reserves or insurance, and (E) equipment leases incurred in the

or permitted to be created or incurred or to exist any Lien upon any of its assets (other than
Permitted Liens), (e) such Consolidated Affiliate has executed the Subsidiary Guaranty, and (f)
such Consolidated Affiliate is not a general partnership. Notwithstanding the foregoing, any
Consolidated Affiliate may guarantee any Unsecured Debt of Borrower or PPT, which guarantee shall
be pari passu with the obligations of such Consolidated Affiliate under the Subsidiary Guaranty.

continuing under Section 10.3(a), (b) or (d), the commitment to extend credit under this Agreement
automatically terminates, the entire unpaid balance of the Obligation automatically becomes due and
payable without any action of any kind whatsoever.

     (b) Other Defaults. If a Default occurs and is continuing, subject to the terms of Section
13.9(b), then Administrative Agent may (and upon the request of the Required Lenders shall), do any
one or more of the following: (i) if the maturity of the Obligation has not already been
accelerated under Section 11.1(a), then declare the entire unpaid balance of all or any part of the
Obligation immediately due and payable, whereupon it is due and payable; (ii) terminate the
commitments of Lenders to extend credit under this Agreement; (iii) reduce any claim to judgment;
and (iv) exercise any and all other legal or equitable Rights afforded by the Loan Documents, the
Governmental Requirements of the State of Texas, or any other applicable jurisdiction.

     11.2 Waivers. To the extent permitted by applicable law, each Company waives presentment and
demand for payment, protest, notice of intention to accelerate, notice of acceleration, and notice
of protest and nonpayment, and agrees that its liability with respect to all or any part of the
Obligation is not affected by any renewal or extension in the time of payment of all or any part of
the Obligation, by any

50

Third Amended and Restated

Credit Agreement

 

indulgence, or by any release or change in any security for the payment of all or any part of
the Obligation.

     11.3 Performance by Administrative Agent. If any covenant, duty, or agreement of Borrower is
not performed in accordance with the terms of the Loan Documents, Administrative Agent may, while a
Default exists, at its option, perform, or attempt to perform that covenant, duty, or agreement on
behalf of Borrower (and any amount expended by Administrative Agent in its performance or attempted
performance is payable by Borrower to Administrative Agent on demand, becomes part of the
Obligation, and bears interest at the Default Rate from the date of Administrative Agent’s
expenditure until paid). However, neither Administrative Agent nor any Lender assumes or shall
have, except by its express written consent, any liability or responsibility for the performance of
any covenant, duty, or agreement of Borrower.

     11.4 Not in Control. None of the covenants or other provisions contained in any Loan Document
shall, or shall be deemed to, give Agents or Lenders the Right to exercise control over the assets
(including real property), affairs, or management of any Company.

     11.5 Course of Dealing. The acceptance by Agents or any Lender of any partial payment on the
Obligation shall not be deemed to be a waiver of any Default then existing. No waiver by any
Credit Party of any Default shall be deemed to be a waiver of any other then-existing or subsequent
Default. No delay or omission by any Credit Party in exercising any Right under the Loan Documents
will impair that Right or be construed as a waiver thereof or any acquiescence therein, nor will
any single or partial exercise of any Right preclude other or further exercise thereof or the
exercise of any other Right under the Loan Documents or otherwise.

     11.6 Cumulative Rights. All Rights available to the Credit Parties under the Loan Documents
are cumulative of and in addition to all other Rights granted to the Credit Parties at law or in
equity, whether or not the Obligation is due and payable and whether or not Agents or Lenders have
instituted any suit for collection, foreclosure, or other action in connection with the Loan
Documents.

     11.7 Application of Proceeds. Any and all proceeds ever received by any Credit Party from the
exercise of any Rights pertaining to the Obligation shall be applied to the Obligation according to
Section 3.11.

     11.8 Certain Proceedings. Borrower shall promptly execute and deliver, or cause the execution
and delivery of, all applications, certificates, instruments, and all other documents and papers
any Agent reasonably requests in connection with the obtaining of any consent, approval,
registration, qualification, permit, license, or authorization of any Governmental Authority or
other Person necessary or appropriate for the effective exercise of any Rights under the Loan
Documents. Because Borrower agrees that Agents’ and Lenders’ remedies at law for failure of
Borrower to comply with the provisions of this paragraph would be inadequate and that failure would
not be adequately compensable in damages, Borrower agrees that the covenants of this Section 11.8
may be specifically enforced.

SECTION 12

AGENTS AND LENDERS

     12.1 Appointment; Nature of Relationship. JPMorgan Chase Bank, N.A. is hereby appointed by
each of the Lenders as its contractual representative (herein referred to as “Administrative
Agent”) hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes

51

Third Amended and Restated

Credit Agreement

 

the Agent, subject to the provisions of Section 12.12, to act as the contractual
representative of such Lender with the rights and duties expressly set forth herein and in the
other Loan Documents. The Agent agrees to act as such contractual representative upon the express
conditions contained in this Section 12. Notwithstanding the use of the defined term
“Administrative Agent” it is expressly understood and agreed that Administrative Agent shall not
have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan
Document and that Administrative Agent is merely acting as the contractual representative of the
Lenders with only those duties as are expressly set forth in this Agreement and the other Loan
Documents. In its capacity as the Lenders’ contractual representative, Administrative Agent (i)
does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a “representative” of
the Lenders within the meaning of the term “secured party” as defined in the Texas Uniform
Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which
are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of
the Lenders hereby agrees to assert no claim against Administrative Agent on any agency theory or
any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby
waives.

     12.2 Powers. Administrative Agent shall have and may exercise such powers under the Loan
Documents as are specifically delegated to Administrative Agent by the terms of each thereof,
together with such powers as are reasonably incidental thereto. Administrative Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder
except any action specifically provided by the Loan Documents to be taken by Administrative Agent.

     12.3 General Immunity. No Agent nor any of their respective directors, officers, agents or
employees shall be liable to any Lender for any action taken or omitted to be taken by it or them
hereunder or under any other Loan Document or in connection herewith or therewith except to the
extent such action or inaction is determined in a final non-appealable judgment by a court of
competent jurisdiction to have arisen from the gross negligence or willful misconduct of such
Person.

     12.4 No Responsibility for Loans, Recitals, etc. No Agent nor any of their respective
directors, officers, agents or employees shall be responsible for or have any duty to ascertain,
inquire into, or verify (a) any statement, warranty or representation made in connection with any
Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants
or agreements of any obligor under any Loan Document, including, without limitation, any agreement
by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition
specified in Section 5, except receipt of items required to be delivered solely to such Agent; (d)
the existence or possible existence of any Default or Potential Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other
instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation,
perfection or priority of any Lien in any collateral security; or (g) the financial condition of
the Borrower or any other Company of any of the Obligation or of any of Borrower’s or any such
Company’s respective Subsidiaries.

     12.5 Action on Instructions of Lenders. Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder and under any other Loan Document in
accordance with written instructions signed by the Required Lenders, and such instructions and any
action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The
Lenders hereby acknowledge that Administrative Agent shall be under no duty to take any
discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or
any other Loan Document unless it shall be requested in writing to do so by the Required Lenders.

     12.6 Employment of Agents and Counsel. Administrative Agent may execute any of its duties as
Administrative Agent hereunder and under any other Loan Document by or through employees,

52

Third Amended and Restated

Credit Agreement

 

agents, and attorneys in fact and shall not be answerable to the Lenders, except as to money
or securities received by it or its authorized agents, for the default or misconduct of any such
agents or attorneys in fact selected by it with reasonable care. Administrative Agent shall be
entitled to advice of counsel concerning the contractual arrangement between Administrative Agent
and the Lenders and all matters pertaining to Administrative Agent’s duties hereunder and under any
other Loan Document.

     12.7 Reliance on Documents; Counsel. Administrative Agent shall be entitled to rely upon any
Note, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex, electronic mail
message, statement, paper or document reasonably believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to legal matters, upon
the opinion of counsel selected by Administrative Agent, which counsel may be employees of
Administrative Agent. For purposes of determining compliance with the conditions specified in
Sections 5.1 and 5.2, each Lender that has signed this Agreement shall be deemed to have consented
to, approved or accepted or to be satisfied with, each document or other matter required thereunder
to be consented to or approved by or acceptable or satisfactory to a Lender unless Administrative
Agent shall have received notice from such Lender prior to the applicable Borrowing Date specifying
its objection thereto.

     12.8 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify
each Agent ratably in proportion to their respective Commitments (or, if the Commitments have been
terminated, in proportion to their Commitments immediately prior to such termination) (i) for any
amounts not reimbursed by Borrower for which such Agent is entitled to reimbursement by Borrower
under the Loan Documents, (ii) for any other expenses incurred by such Agent on behalf of the
Lenders, in connection with the preparation, execution, delivery, administration and enforcement of
the Loan Documents (including, without limitation, for any expenses incurred by such Agent in
connection with any dispute between such Agent and any Lender or between two or more of the
Lenders) and (iii) for any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against such Agent in any way relating to or arising out of the
Loan Documents or any other document delivered in connection therewith or the transactions
contemplated thereby (including, without limitation, for any such amounts incurred by or asserted
against such Agent in connection with any dispute between such Agent and any Lender or between two
or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any
such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the
extent any of the foregoing is found in a final non-appealable judgment by a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of such Agent and
(ii) any indemnification required pursuant to Section 3.15 shall, notwithstanding the provisions of
this Section 12.8, be paid by the relevant Lender in accordance with the provisions thereof. The
obligations of the Lenders under this Section 12.8 shall survive payment of the Obligation and
termination of this Agreement.

     12.9 Notice of Default. Administrative Agent shall not be deemed to have knowledge or notice
of the occurrence of any Default or Potential Default hereunder, except with respect to the payment
obligations of Borrower under the Notes and the Swing Line Note, unless Administrative Agent has
received written notice from a Lender or Borrower referring to this Agreement describing such
Default or Potential Default and stating that such notice is a “notice of default”. In the event
that Administrative Agent receives such a notice, Administrative Agent shall give prompt notice
thereof to the Lenders.

     12.10 Rights as a Lender. In the event any Agent is a Lender, such Agent shall have the same
rights and powers hereunder and under any other Loan Document with respect to its Commitment and
its Loans as any Lender and may exercise the same as though it were not an Agent, and the term
“Lender” or “Lenders” shall, at any time when such Agent is a Lender, unless the context otherwise
indicates, include

53

Third Amended and Restated

Credit Agreement

 

such Agent in its individual capacity. Each Agent and its respective Affiliates may accept
deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other
transaction, in addition to those contemplated by this Agreement or any other Loan Document, with
Borrower or any other Company in which any Company is not restricted hereby from engaging with any
other Person.

     12.11 Lender Credit Decision. Each Lender acknowledges that it has, independently and without
reliance upon Administrative Agent, the Arranger or any other Lender and based on the financial
statements prepared by Borrower and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement and the other
Loan Documents. Each Lender also acknowledges that it will, independently and without reliance
upon Agents or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action
under this Agreement and the other Loan Documents. Except for any notice, report, document or other
information expressly required to be furnished to the Lenders by Agents hereunder, no Agent shall
have any duty or responsibility (either initially or on a continuing basis) to provide any Lender
with any notice, report, document, credit information or other information concerning the affairs,
financial condition or business of Borrower or any of its Affiliates that may come into the
possession of any Agent or any of their Affiliates.

     12.12 Successor Agent. Administrative Agent may resign at any time by giving thirty (30) days
prior written notice thereof to the Lenders and Borrower, such resignation to be effective upon the
appointment of a successor Administrative Agent or, if no successor Administrative Agent has been
appointed, forty-five (45) days after the retiring Administrative Agent gives notice of its
intention to resign. Administrative Agent may be removed at any time with or without cause by
written notice received by Administrative Agent from the Required Lenders, such removal to be
effective on the date specified by the Required Lenders. Upon any such resignation or removal, the
Required Lenders shall have the right to appoint, on behalf of Borrower and the Lenders, a
successor Administrative Agent (which, if no Default or Potential Default exists, is subject to
Borrower’s approval that may not be unreasonably withheld), which must be a commercial bank having
a combined capital and surplus of at least $1,000,000,000 (as shown on its most recently published
statement of condition) and whose debt obligations (or whose parent’s debt obligations) are rated
not less than Baa1 by Moody’s or BBB+ by S & P. If no successor Administrative Agent shall have
been so appointed by the Required Lenders within thirty (30) days after the resigning
Administrative Agent’s giving notice of its intention to resign, then the resigning Administrative
Agent may appoint, on behalf of Borrower and the Lenders, a successor Administrative Agent (which,
if no Default or Potential Default exists, is subject to Borrower’s approval that may not be
unreasonably withheld), which must be a commercial bank having a combined capital and surplus of at
least $1,000,000,000 (as shown on its most recently published statement of condition) and whose
debt obligations (or whose parent’s debt obligations) are rated not less than Baa1 by Moody’s or
BBB+ by S & P. Notwithstanding the previous sentence, Administrative Agent may at any time without
the consent of Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as
a successor Administrative Agent hereunder. If Administrative Agent has resigned or been removed
and no successor Administrative Agent has been appointed, the Lenders may perform all the duties of
Administrative Agent hereunder and Borrower shall make all payments in respect of the Obligation to
the applicable Lender and for all other purposes shall deal directly with the Lenders. No
successor Administrative Agent shall be deemed to be appointed hereunder until such successor
Administrative Agent has accepted the appointment. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and
duties of the resigning or removed Administrative Agent. Upon the effectiveness of the resignation
or removal of the Administrative Agent, the resigning or removed Administrative Agent shall be
discharged from its duties and obligations hereunder and under the Loan Documents. After the
effectiveness of the resignation or

54

Third Amended and Restated

Credit Agreement

 

removal of Administrative Agent, the provisions of this Section 12 shall continue in effect
for the benefit of such Administrative Agent in respect of any actions taken or omitted to be taken
by it while it was acting as Administrative Agent hereunder and under the other Loan Documents.

     12.13 Delegation to Affiliates. Borrower and the Lenders agree that Administrative Agent may
delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and
such Affiliate’s directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other
protective provisions to which Administrative Agent is entitled under Sections 12 and 13.

     12.14 Syndication Agent. Syndication Agent, in such capacity, shall have no rights, duties,
or obligations hereunder, except as specifically provided in this Agreement. Syndication Agent (a)
may voluntarily resign by notice to Administrative Agent, Lenders, and Borrower, and (b) shall
resign upon the request of the Required Lenders for cause. Upon the resignation of Syndication
Agent, the Required Lenders may elect to designate a successor Syndication Agent (which, if no
Default or Potential Default exists, is subject to Borrower’s approval that may not be unreasonably
withheld), which must be a Lender who is a commercial bank having a combined capital and surplus of
at least $1,000,000,000 (as shown on its most recently published statement of condition) and whose
debt obligations (or whose parent’s debt obligations) are rated not less than Baa1 by Moody’s or
BBB+ by S & P.

     12.15 Other Agents. Neither any of the Lenders identified in this Agreement as a “co-agent”
nor the Documentation Agent shall have any right, power, obligation, liability, responsibility or
duty under this Agreement other than those applicable to all Lenders as such. Without limiting the
foregoing, none of such Lenders shall have or be deemed to have a fiduciary relationship with any
Lender. Each Lender hereby makes the same acknowledgments with respect to such Lenders as it makes
with respect to Administrative Agent in Section 12.11.

     12.16 Approval of Lenders.

     (a) All communications from Administrative Agent to Lenders requesting Lenders’ determination,
consent, approval, or disapproval (i) shall be given in the form of a written notice to each
Lender, (ii) shall be accompanied by a description of the matter or thing as to which such
determination, approval, consent, or disapproval is requested, or shall advise each Lender where
such matter or thing may be inspected, or shall otherwise describe the matter or issue to be
resolved, (iii) shall include, if reasonably requested by a Lender and to the extent not previously
provided to such Lender, written materials and a summary of all oral information provided to
Administrative Agent by Borrower in respect of the matter or issue to be resolved, and (iv) shall
include Administrative Agent’s recommended course of action or determination in respect thereof.
Each Lender shall reply promptly, but in any event (x) within thirty (30) days (or such lesser
period as may be required under the Loan Documents for Administrative Agent to respond) for those
matters requiring the consent by all Lenders, and (y) within fifteen (15) Business Days (or such
lesser period as may be required under the Loan Documents for Administrative Agent to respond) for
those matters requiring the consent by the Required Lenders, in each instance, after receipt of the
request therefore by Administrative Agent (in either event, the “Lender Reply Period”).

     (b) Unless a Lender shall give written notice to Administrative Agent that it objects to the
recommendation or determination of Administrative Agent within the Lender Reply Period, such Lender
shall be deemed to have approved of or consented to such recommendation or determination.

SECTION 13

MISCELLANEOUS

     13.1 Headings. The headings, captions and arrangements used in any of the Loan Documents are,
unless specified otherwise, for convenience only and shall not be deemed to limit, amplify, or
modify the terms of the Loan Documents, nor affect the meaning thereof.13.2 Nonbusiness Days; Time.
Any payment or action that is due under any Loan Document on a non-Business Day may be delayed
until the next-succeeding Business Day (but interest shall continue to accrue on any applicable
payment until payment is in fact made) unless the payment concerns a Eurodollar Borrowing, in which
case if the next-succeeding Business Day is in the next calendar month, then such payment shall be
made on the next-preceding Business Day.

     13.3 Communications. Unless otherwise specifically provided, whenever any Loan Document
requires or permits any consent, approval, notice, request, demand, or other communication from one
party to another, communication must be in writing (which may be by telex or telecopy) to be
effective and shall be deemed to have been given (a) if by telex, when transmitted to the
appropriate telex number and the appropriate answerback is received, (b) if by telecopy, when
transmitted to the appropriate telecopy number (and all communications sent by telecopy must be
confirmed promptly thereafter by telephone; but any requirement in this parenthetical shall not
affect the date when the telecopy shall be deemed to have been delivered), (c) if by mail, on the
fifth (5th) Business Day after it is enclosed in an envelope and properly addressed, stamped,
sealed, certified mail, return receipt requested, and deposited in the appropriate official postal
service, or (d) if by any other means, when actually delivered. Until changed by notice pursuant
to this Agreement, the address (and telecopy number) for each party to a Loan Document is set forth
on Schedule 1.

     13.4 Form and Number of Documents. The form, substance, and number of counterparts of each
writing to be furnished under this Agreement must be satisfactory to Agents and their counsel.

     13.5 Survival. All covenants, agreements, undertakings, representations, and warranties made
in any of the Loan Documents survive all closings under the Loan Documents and, except as otherwise
indicated, are not affected by any investigation made by any party.

     13.6 Governing Law. Except as expressly provided in a Loan Document, the Governmental
Requirements (other than conflict-of-laws provisions) of the State of Texas and of the United
States of America govern the Rights and duties of the parties to the Loan Documents and the
validity, construction, enforcement, and interpretation of the Loan Documents.

     13.7 Invalid Provisions. Any provision in any Loan Document held to be illegal, invalid, or
unenforceable is fully severable; the appropriate Loan Document shall be construed and enforced as
if that provision had never been included; and the remaining provisions shall remain in full force
and effect and shall not be affected by the severed provision. Agents, Lenders, and Borrower agree
to negotiate, in good faith, the terms of a replacement provision as similar to the severed
provision as may be possible and be legal, valid and enforceable. However, if the provision held
to be illegal, invalid, or unenforceable is a material part of this Agreement, such invalid,
illegal, or unenforceable provision shall be, to the extent permitted by applicable law, replaced
by a clause or provision judicially construed and interpreted to be as similar in substance and
content to the original terms of such illegal, invalid, or unenforceable clause or provision as the
context thereof would reasonably allow, so that such clause or provision would thereafter be legal,
valid, and enforceable.

AFFILIATES), (a) IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL
COURTS OF THE STATE OF TEXAS, (b) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY

OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT. The scope of each of the
foregoing waivers is intended to be all-encompassing of any and all disputes that may be filed in
any court and that relate to the subject matter of this transaction, including contract claims,
tort claims, breach of duty claims, and all other common law and statutory claims. Borrower (for
itself and on behalf of each of its Consolidated Affiliates) acknowledges that these waivers are a
material inducement to Administrative Agent’s and each Lender’s agreement to enter into a business
relationship, that Administrative Agent and each Lender has already relied on these waivers in
entering into this Agreement, and that Administrative Agent and each Lender will continue to rely
on each of these waivers in related future dealings. Borrower (for itself and on behalf of each of
its Consolidated Affiliates) further warrants and represents that it has reviewed these waivers
with its legal counsel, and that it knowingly and voluntarily agrees to each waiver following
consultation with legal counsel. THE WAIVERS IN THIS SECTION 13.8 ARE IRREVOCABLE, MEANING THAT
THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THESE WAIVERS SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, SUPPLEMENTS, OR REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN DOCUMENT. In

     13.9 Amendments, Consents, Conflicts, and Waivers.

     (a) Required Lenders. Unless otherwise specifically provided, the provisions of this
Agreement may be amended, modified, or waived, only by an instrument in writing executed by
Borrower and the Required Lenders and supplemented only by documents delivered or to be delivered
in accordance with the express terms of this Agreement.

     (b) All Lenders. Except as specifically otherwise provided in this Section 13.9, any
amendment to or consent or waiver under this Agreement or any Loan Document that purports to
accomplish any of the following must be by an instrument in writing executed by Borrower and

scheduled payment

57

or amortization of the Obligation beyond the date specified in the Loan Documents; (iii)

(vi) waives compliance with, amends, or fully or partially releases any Obligor; (vii) permits any

or obligations of any Agent shall be effective without the consent of such Agent.

     (d) Conflicts. Any conflict or ambiguity between the terms and provisions of this Agreement
and terms and provisions in any other Loan Document is controlled by the terms and provisions of
this Agreement.

     (e) Course of Dealing. No course of dealing or any failure or delay by any Credit Party or
any of its Representatives with respect to exercising any Right of any Credit Party under this
Agreement operates as a waiver thereof. A waiver must be in writing and signed by the Required
Lenders or Lenders, as appropriate, to be effective, and a waiver will be effective only in the
specific instance and for the specific purpose for which it is given.

     13.10 Multiple Counterparts. Any Loan Document may be executed in a number of identical
counterparts, each of which shall be deemed an original for all purposes and all of which
constitute, collectively, one agreement; but, in making proof of thereof, it shall not be necessary
to produce or account for more than one counterpart. Each Lender need not execute the same
counterpart of this Agreement so long as identical counterparts are executed by Borrower, each
Lender, and each Agent. This Agreement shall become effective when counterparts of this Agreement
have been executed and delivered to Administrative Agent by each Lender, each Agent, and Borrower,
or, in the case only of Lenders, when Administrative Agent has received telecopied, telexed, or
other evidence satisfactory to it that each Lender has executed and is delivering to Administrative
Agent a counterpart of this Agreement.

     (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, except that Borrower

any Letter of Credit), Participants to the extent provided in subsection (d) of this Section 13.11
and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right,
remedy or claim under or by reason of this Agreement.

     (b) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of
its Rights and obligations under this Agreement (including all or a portion of its Commitment and
Note (including for purposes of this subsection (b), participations in Swing Line Loans) at the
time owing to it); provided that (i) except for an assignment by such Lender to an Affiliate of
such Lender, such Lender

has occurred and is continuing, Borrower (each such consent not to be unreasonably withheld or
delayed); (ii) except in the case of an assignment of the entire remaining amount of the assigning
Lender’s Commitment and Note at the time owing to it or in the case of an assignment to a Lender or

such assignment, determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to Administrative Agent or, if “Trade Date” is specified in the Assignment
and Assumption, as of the Trade Date, shall not be less than $5,000,000; (iii) 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 with respect to the Notes or the Commitment assigned,
except that this clause (iii) shall not apply to rights in respect of Swing Line Loans; (iv) the
parties to each assignment shall execute and deliver to Administrative Agent an Assignment and
Assumption, together with a processing and recordation fee of $3,500; and (v) except in the case of
an assignment of the entire remaining amount of the assigning Lender’s Commitment and Principal
Debt at the time, the aggregate amount of the Commitments of such assigning Lender or, if the Total
Commitment is not then in effect, the Principal Debt of the Notes of such assigning Lender, after
giving effect to such assignment, is at least $5,000,000. Subject to acceptance and recording
thereof by Administrative Agent pursuant to subsection (c) of this Section 13.11, from and after
the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder
shall be a party to this Agreement 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 3.15(c) and (d), 3.17, 7.7 and 7.12 with respect to facts and circumstances occurring
prior to the effective date of such assignment). Upon request, Borrower (at its expense) shall
execute and deliver a Note to the assignee Lender. Administrative Agent agrees to provide Borrower
with copies of all Assignment and Assumption Agreements so long as no Default exists. Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this subsection 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 subsection (d) of this
Section 13.11.

     (c) Administrative Agent, acting solely for this purpose as an agent of Borrower, shall
maintain at Administrative Agent’s office 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 Commitments
of, and principal amounts of the Notes owing to, each Lender pursuant to the terms hereof from time
to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error,
and Borrower, Administrative Agent, and 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 Borrower
and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

     (d) Any Lender may at any time, sell participations to any Person (other than a natural
person or Borrower or any of Borrower’s Affiliates or Subsidiaries ) (each, a “Participant”) in all
or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a
portion of its Commitment and/or the Notes (including such Lender’s participations in Swing Line
Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) Borrower, Administrative Agent, and the other Lenders shall
continue to deal solely and directly with

Third Amended and Restated

Credit Agreement

 

such Lender in connection with such Lender’s rights and obligations under this Agreement, (iv)
the amount of each such participation shall not be less than $5,000,000; and (v) the aggregate
amount of the Commitments of such Lender selling such participation or, if the Total Commitment is
not then in effect, the Principal Debt of the Notes of the Lender selling such participation, after
giving effect to such participation, is at least $5,000,000. 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, waiver or other
modification described in Section 13.9(b) that directly affects such Participant. Subject to
subsection (e) of this Section 13.11, Borrower agrees that each Participant shall be entitled to
the benefits of Sections 3.15(c) and (d) and 3.17 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to subsection (b) of this Section 13.11. To the
extent permitted by law, each Participant also agrees to be subject to Section 3.12 as though it
were a Lender.

     (e) A Participant shall not be entitled to receive any greater payment under Sections 3.15(c)
and (d) than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 3.15(d) unless Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of Borrower, to
comply with Section 3.18 as though it were a Lender.

     (f) Any Lender may at any time pledge or assign a security interest in all or any portion of
its Rights under this Agreement (including under its Note) to secure obligations of such Lender,
including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that
no such pledge or assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

     (g) As used herein, the following terms have the following meanings:

     “Approved Fund” means any Fund 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.

     “Eligible Assignee” means (a) a Lender; (b) an Affiliate of a Lender; (c) an Approved Fund;
and (d) any other Person (other than a natural person) approved by (i) the Agents, and (ii) unless
a Default or Potential Default has occurred and is continuing, Borrower (each such approval not to
be unreasonably withheld or delayed); provided that notwithstanding the foregoing, “Eligible
Assignee” shall not include Borrower or any of Borrower’s Affiliates or Subsidiaries.

     “Fund” means any Person (other than a natural person) that is (or will be) engaged in making,
purchasing, holding or otherwise investing in commercial loans and similar extensions of credit in
the ordinary course of its business.

     (h) Prior to the expiration or termination of the Total Commitment, and unless a Default
exists or Borrower otherwise consents in writing, each Agent shall, at all times prior to its
resignation or replacement as either Administrative Agent or Syndication Agent, as the case may be,
hereunder, retain a minimum Commitment equal to the greater of (i) $20,000,000, and (ii) an amount
equal to the largest Commitment held by any Lender under this Agreement (without giving effect to
any mergers of any Lenders other than any Agent).

Third Amended and Restated

Credit Agreement

 

     13.12 Discharge Only Upon Payment in Full; Reinstatement in Certain Circumstances. Borrower’s
obligations under the Loan Documents remain in full force and effect until the Total Commitment is
terminated, all Letters of Credit have expired or terminated, and the Obligation is paid in full
(except for provisions under the Loan Documents which by their terms expressly survive payment of
the Obligation and termination of the Loan Documents). If at any time any payment of the principal
of or interest on any Note or any other amount payable by Borrower or any other obligor on the
Obligation under any Loan Document is rescinded or must be restored or returned upon the
insolvency, bankruptcy, or reorganization of Borrower or otherwise, then the obligations of
Borrower under the Loan Documents with respect to that payment shall be reinstated as though the
payment had been due but not made at that time.

     13.13 Patriot Act Notification. The following notification is provided to Borrower pursuant
to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

     IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government
fight the funding of terrorism and money laundering activities, Federal law requires all financial
institutions to obtain, verify, and record information that identifies each person or entity that
opens an account, including any deposit account, treasury management account, loan, other extension
of credit, or other financial services product. What this means for Borrower: When a Borrower
opens an account, if such Borrower is an individual, Administrative Agent and Lenders will ask for
such Borrower’s name, residential address, tax identification number, date of birth, and other
information that will allow Administrative Agent and Lenders to identify such Borrower, and, if
Borrower is not an individual, Administrative Agent and Lenders will ask for Borrower’s name, tax
identification number, business address, and other information that will allow Administrative Agent
and Lenders to identify Borrower. Administrative Agent and Lenders may also ask, if Borrower is an
individual, to see such Borrower’s driver’s license or other identifying documents, and, if
Borrower is not an individual, to see such Borrower’s legal organizational documents or other
identifying documents.

     13.14 Restatement of Original Agreement. The parties hereto agree that, on the Closing Date,
after all conditions precedent set forth in Section 5.1 have been satisfied or waived: (a) the
Obligation (as defined herein) represents, among other things, the amendment, extension,
consolidation, and modification of the “Obligation” (as defined in the Original Agreement); (b)
this Agreement is intended to, and does hereby, restate, renew, extend, amend, modify, supersede,
and replace the Original Agreement; (c) the Notes and the Swing Line Note executed pursuant to this
Agreement amend, renew, extend, modify, replace, substitute for and supersede in their entirety
(but do not extinguish, the Indebtedness arising under) the promissory notes issued pursuant to the
Original Agreement; and (d) the entering into and performance of their respective obligations under
this Agreement and the transactions evidenced hereby do not constitute a novation.

     13.15 Entirety. THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS (EACH AS AMENDED IN
WRITING FROM TIME TO TIME) EXECUTED BY BORROWER AND/OR ANY CREDIT PARTY REPRESENT THE FINAL
AGREEMENT AMONG BORROWER AND THE CREDIT PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS AMONG THE PARTIES.

SECOND AMENDED AND RESTATED CREDIT AGREEMENT

THIS SECOND AMENDED AND RESTATED CREDIT AGREEMENT is dated as of ___, 2005 (the “Closing
Date”), among PRENTISS PROPERTIES ACQUISITION PARTNERS, L.P., a Delaware limited partnership
(“Borrower”), each of the lenders that are a signatory hereto (each such lender, together with each
lender that becomes a signatory hereto as provided in Section 13.11(b), being individually,
together with its successors and assigns, a “Lender” and collectively, the “Lenders”), and EUROHYPO
AG, NEW YORK BRANCH, as Administrative Agent (in such capacity, together with its successors and
assigns, “Administrative Agent”).

R E C I T A L S:

     1. Reference is hereby made to that certain Amended and Restated Credit Agreement dated as of
March 2, 2004, executed by Borrower, Lenders, and Administrative Agent (as renewed, extended,
modified, and amended through the date hereof, the “Original Agreement”).

     2. Borrower, Administrative Agent, and the Lenders desire to amend, modify, renew, and restate
the Original Agreement in the form of this Agreement to modify certain terms, conditions, and
covenants contained in the Original Agreement.

     3. Upon and subject to the terms and conditions of this Agreement, the parties hereto are
willing to amend and restate the Original Agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree that the Original Agreement shall be amended and
restated as follows:

SECTION 1

DEFINITIONS AND TERMS

     1.1 Definitions. Unless otherwise indicated, as used in the Loan Documents:

     “Adjusted Aggregate EBITDA” means, for any period, (a) Aggregate EBITDA, minus (b) the EBITDA
Adjustments, on a Consolidated Basis, for all Properties.

     “Adjusted Property EBITDA” means, for any Property, the product of (a) the difference between
(i) the EBITDA of such Property, minus (ii) the EBITDA Adjustments for such Property, in each case
for the three (3) month period ending on the last day of the fiscal quarter immediately preceding
such determination date, times (b) four (4). For Properties owned for less than three (3) months
as of the date of determination, EBITDA of all such Properties shall be equal to the lesser of (I)
the product of (x) the Approved Costs of such Properties, times (y) eight percent (8%), and (II)
Borrower’s most-recent asset manager’s forecasts for the EBITDA of such Properties for the first
(1st) calendar quarter following acquisition thereof; provided that if Administrative Agent shall
reasonably determine that such amount is not an appropriate computation of EBITDA of any such
Property, then EBITDA for all such Properties shall be based upon the most recent three (3) month
period available.

     “Administrative Agent” is defined in the preamble.

     “Advanced Amount” is defined in Section 12.11.

 

 

     “Affiliate” of a Person means any other individual or entity who directly or indirectly
controls, or is controlled by, or is under common control with, that Person. For purposes of this
definition “control,” “controlled by,” and “under common control with” mean possession, directly or
indirectly, of power to direct (or cause the direction of) management or policies (whether through
ownership of Stock, by contract, or otherwise).

     “Aggregate EBITDA” means EBITDA of the Companies, for any period, as determined on a
Consolidated Basis.

     “Agreement” means this Credit Agreement, as modified, amended, supplemented, or restated from
time to time.

     “Anti-Terrorism Financing Laws” is defined in Section 6.20.

     “Applicable Amount” means (a) with respect to a Contract Property, the lesser of (i) the
purchase price of such Contract Property (or the Stock of the Person that owns such Contract
Property), and (ii) the maximum personal liability of the Companies to pay such purchase price as
determined by Borrower in a manner reasonably acceptable to Administrative Agent, and (b) with
respect to a Development Property, the unpaid balance of any Liabilities incurred to finance the
costs of constructing or developing such Development Property to the extent that a Company is
obligated (as guarantor or otherwise) with respect to such Liabilities.

     “Applicable Margin” means, at the time of determination thereof:

     (a) For any period in which an Investment Grade Rating does not exist, the interest margin
over the Eurodollar Rate and the Base Rate, as the case may be, shall be based upon the Index Ratio
as follows:

	 	 	 	 	 	 	 	 	 
	 	 	Applicable Margin	 	Applicable Margin
	 	 	for Eurodollar	 	for Base Rate
	Index Ratio	 	Borrowings	 	Borrowings
	 
	Greater than or equal to 0.55 to 1.0

	 	 	1.35	%	 	 	0	%
	 
	 	 	 	 	 	 	 	 
	Less than 0.55 to 1.0 but greater than
or equal to 0.50 to 1.0

	 	 	1.20	%	 	 	0	%
	 
	 	 	 	 	 	 	 	 
	Less than 0.50 to 1.0 but greater than
or equal to 0.45 to 1.0

	 	 	1.05	%	 	 	0	%
	 
	 	 	 	 	 	 	 	 
	Less than 0.45 to 1.0 but greater than
or equal to 0.35 to 1.0

	 	 	0.95	%	 	 	0	%
	 
	 	 	 	 	 	 	 	 
	Less than 0.35 to 1.0

	 	 	0.85	%	 	 	0	%

The Index Ratio shall be determined from the Compliance Certificate delivered to
Administrative Agent pursuant to Section 7.1; provided that the initial Applicable Margin shall be
based upon the Compliance Certificate dated as of March 31, 2005. The adjustment, if any, to the
Applicable Margin shall be effective commencing on the fifth (5th) Business Day after delivery of
such Compliance Certificate. If

2

 

Borrower fails at any time to furnish to Administrative Agent the Compliance Certificate as
required to be delivered pursuant to Section 7.1, then the maximum Applicable Margin shall apply
until such time as such Compliance Certificate is so delivered.

     (b) Beginning with the period commencing on the date of delivery by Borrower to Administrative
Agent of notice that Borrower achieved an Investment Grade Rating, and continuing until the public
announcement of a downgrade resulting in Borrower no longer having an Investment Grade Rating the
interest margin over the Eurodollar Rate and the Base Rate, as the case may be, shall be based upon
the Applicable Rating as follows:

	 	 	 	 	 	 	 	 	 	 	 
	 	 	 	 	 	 	 	 	Applicable	 	Applicable
	 	 	 	 	 	 	 	 	Margin for	 	Margin
	 	 	Moody's	 	 	 	Third Agency	 	Eurodollar	 	for Base Rate
	Level	 	Rating	 	S & P Rating	 	Rating	 	Borrowings	 	Borrowings
	 
	 
	 	 	 	 	 	 	 	 	 	 
	1
	 	A3 or higher	 	A- or higher	 	A- or higher	 	0.50%	 	0.00%
	 
	 	 	 	 	 	 	 	 	 	 
	2
	 	Baa1	 	BBB+	 	BBB+	 	0.525%	 	0.00%
	 
	 	 	 	 	 	 	 	 	 	 
	3
	 	Baa2	 	BBB	 	BBB	 	0.65%	 	0.00%
	 
	 	 	 	 	 	 	 	 	 	 
	4
	 	Baa3	 	BBB-	 	BBB-	 	0.80%	 	0.00%

     The “Applicable Rating” shall be determined as follows: (i) if a Debt Rating is issued by only
two (2) of Moody’s, S & P, and a Third Agency, and (A) such Debt Ratings shall fall within
different Levels (but not more than one (1) Level apart), then the Applicable Rating shall be the
higher of such Debt Ratings (e.g. if the Moody’s Rating is at Level 1 and the S & P Rating is at
Level 2, then the Applicable Rating shall be determined by reference to Level 1), (B) such Debt
Ratings shall fall within different Levels (two (2) or more Levels apart), the Applicable Rating
shall be the Debt Rating at the midpoint between the highest Debt Rating and the lowest Debt Rating
(e.g. if the Moody’s Rating is at Level 1 and the S & P Rating is at Level 3, then the Applicable
Rating shall be determined by reference to Level 2); provided however, that if there is no such
midpoint, then the Applicable Rating shall be determined by reference to the Level which is the
higher Debt Rating of the two intermediate Debt Ratings (e.g., if the S & P Rating is at Level 1
and the Moody’s Rating is at Level 4, then the Applicable Margin shall be determined by reference
to Level 2); and (ii) if a Debt Rating is issued by each of Moody’s, S & P, and a Third Agency,
then the Applicable Rating shall be the lower of the two (2) highest such Debt Ratings (e.g. if the
Moody’s Rating is at Level 1, the S & P Rating is at Level 2, and the Third Agency Rating is at
Level 3, then the Applicable Rating shall be determined by reference to Level 2). Each change in
the Applicable Rating based upon a publicly announced change in the Debt Rating shall be effective
during the period commencing on the date of the public announcement thereof and ending on the date
immediately preceding the effective date of the next such change.

     “Approved Costs” means, for any Property, the sum of the acquisition, construction, and other
capitalized costs incurred for such Property (or the Stock of the Company that owns such Property),
whether in the form of cash, property, liabilities assumed, or other consideration.

     “Approved Fund” is defined in Section 13.11(g).

3

 

     “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 13.11), and accepted
by the Administrative Agent, in the form of Exhibit E attached hereto, or any other form
approved by the Administrative Agent.

     “Assumed Interest Expense” means, as of any date, the product of (a) the aggregate amount of
all Unsecured Debt of the Companies as of such date, times (b) the weighted average interest rate
per annum on all such Unsecured Debt as of such date.

     “Base Rate” means, for any day, the greater of (a) the sum of the Federal Funds Rate plus
one-half of one percent (0.5%), and (b) the annual interest rate most recently announced by
Administrative Agent as its prime rate (or, if the Person then acting as Administrative Agent under
this Agreement is not a bank organized under the Governmental Requirements of the United States or
any State, then the rate announced by Eurohypo, or any successor thereof, as its prime rate) in
effect at its principal office, automatically fluctuating upward and downward with and as specified
in each announcement without special notice to Borrower or any other Person (which prime rate may
not necessarily represent the lowest or best rate actually charged to a customer).

     “Base Rate Borrowing” means a Borrowing bearing interest at the Base Rate plus the Applicable
Margin.

     “Binding Agreement” means a binding agreement pursuant to which a Company has agreed to
purchase a Contract Property or a Development Property from another Person and in which such Person
may enforce rights and remedies at law or in equity against a Company for failure to purchase such
Contract Property or Development Property and which remedies are not limited to retaining earnest
money, escrow, liquidated damages not to exceed ten percent (10%) of the applicable purchase price,

this Agreement, then that portion may not be reborrowed. The Term Loans shall bear interest from
time to time in accordance with selections made by Borrower from time to time pursuant to Section
3.4.

SECTION 3

TERMS OF PAYMENT

     3.1 Notes and Payments.

     (a) The Total Principal Debt shall be evidenced by the Notes, which Notes shall be payable to
Lenders in the aggregate stated principal amount of the Term Loans.

     (b) Borrower must make each payment and prepayment on the Obligation, without offset,
counterclaim, or deduction, to Administrative Agent’s principal office in New York, New York, in
funds that will be available for immediate use by Administrative Agent by 12:00 noon on the day
due. Payments received after such time shall be deemed received on the next Business Day.
Administrative Agent shall pay to each Lender any payment to which such Lender is entitled on the
same day Administrative Agent receives the funds from Borrower if Administrative Agent receives the
payment or prepayment before 12:00 noon, and otherwise before 12:00 noon on the following Business
Day. If and to the extent that Administrative Agent does not make payments to Lenders when due,
then Administrative Agent shall be obligated to pay to Lenders such unpaid amounts together with
interest at the Federal Funds Rate from the due date until (but not including) the payment date.

     3.2 Interest and Principal Payments

     (a) Interest Payments. Accrued interest on each Borrowing is due and payable on the first
(1st) day of each calendar month during the term of this Agreement, commencing on___, 2005,
and on the Termination Date.

     (b) Principal Payments. The Total Principal Debt is due and payable on the Termination Date.

     (c) Voluntary Prepayment. Borrower may voluntarily repay or prepay all or any part of the
Total Principal Debt at any time without premium or penalty, subject to the following conditions:

     (i) Administrative Agent must receive Borrower’s written payment notice by 11:00 a.m.
on (A) the Business Day preceding the date of payment of a Eurodollar Borrowing, and (B)
the Business Day preceding the date of payment of a Base Rate Borrowing, which shall
specify the payment date and the Type and amount of the Borrowing(s) to be paid, and which

19

 

shall constitute an irrevocable and binding obligation of Borrower to make a repayment or
prepayment on the designated date;

     (ii) each partial repayment or prepayment must be in a minimum amount of at least
$1,000,000 or a greater integral multiple of $100,000, or, if less, the Total Principal
Debt; and

     (iii) Borrower shall pay any related Funding Loss upon demand.

     3.3 Interest Options. Except as specifically otherwise provided, Borrowings shall bear
interest at an annual rate equal to the lesser of (a) the Base Rate plus the Applicable Margin, or
the Eurodollar Rate plus the Applicable Margin (in each case as designated or deemed designated by
Borrower and, in the case of Eurodollar Borrowings, for the Interest Period designated by
Borrower), and (b) the Maximum Rate. Each change in the Base Rate and Maximum Rate is effective,
without notice to Borrower or any other Person, upon the effective date of change.

     3.4 Quotation of Rates. A Representative of Borrower may call Administrative Agent before
delivering a Borrowing Request to receive an indication of the interest rates then in effect, but
the indicated rates do not bind Administrative Agent or Lenders or affect the interest rate that is
actually in effect when Borrower delivers its Borrowing Request or on the Borrowing Date.

     3.5 Default Rate. At the option of the Required Lenders at any time while a Default exists
and to the extent permitted by applicable law, all Principal Debt, accrued interest thereon, and
fees and expenses payable hereunder and under the other Loan Documents shall bear interest at the
Default Rate until paid, regardless of whether such payment is made before or after entry of a
judgment.

     3.6 Interest Recapture. If the designated interest rate applicable to any Borrowing exceeds
the Maximum Rate, then the interest rate on that Borrowing is limited to the Maximum Rate, provided
that any subsequent reductions in the designated rate shall not reduce the interest rate thereon
below the Maximum Rate until the total amount of accrued interest equals the amount of interest
that would have accrued if the designated rate had always been in effect. If at maturity (stated
or by acceleration), or at final payment of the Notes, the total interest paid or accrued is less
than the interest that would have accrued if the designated rates had always been in effect, then,
at that time and to the extent permitted by applicable law, Borrower shall pay an amount equal to
the difference between (a) the lesser of the amount of interest that would have accrued if the
designated rates had always been in effect and the amount of interest that would have accrued if
the Maximum Rate had always been in effect, and (b) the amount of interest actually paid or accrued
on the Notes.

     3.7 Interest Calculation

     (a) Interest shall be calculated on the basis of actual number of days elapsed (including the
first day but excluding the last day) but computed as if each calendar year consisted of 360 days
for all Borrowings (unless the calculation would result in an interest rate greater than the
Maximum Rate, in which event interest shall be calculated on the basis of a year of 365 or 366
days, as the case may be). All interest rate determinations and calculations by Administrative
Agent are conclusive and binding absent manifest error.

     (b) The provisions of this Agreement relating to calculation of the Base Rate and the
Eurodollar Rate are included only for the purpose of determining the rate of interest or other
amounts to be paid under this Agreement that are based upon those rates. Each Lender may fund and
maintain its funding of all or any part of each Borrowing as it selects.

20

 

     3.8 Maximum Rate. Regardless of any provision contained in any Loan Document or any document
related thereto, it is the intent of the parties to this Agreement that no Credit Party may
contract for, charge, take, reserve, receive or apply, as interest on all or any part of the
Obligation any amount in excess of the Maximum Rate or the Maximum Amount or receive any unearned
interest in violation of any applicable law, and, if any Credit Party ever does so, then any excess
shall be treated as a partial repayment or prepayment of principal and any remaining excess shall
be refunded to Borrower. In determining if the interest paid or payable exceeds the Maximum Rate,
Borrower and the Credit Parties shall, to the maximum extent permitted under applicable law, (a)
treat all Borrowings as but a single extension of credit (and Lenders and Borrower agree that this
is the case and that provision in this Agreement for multiple Borrowings is for convenience only),
(b) characterize any non-principal payment as an expense, fee or premium rather than as interest,
(c) exclude voluntary repayments or prepayments and their effects, and (d) amortize, prorate,
allocate and spread the total amount of interest throughout the entire contemplated term of the
Obligation. If, however, the Obligation is paid in full before the end of its full contemplated
term, and if the interest received for its actual period of existence exceeds the Maximum Amount,
then Lenders shall refund any excess (and Lenders may not, to the extent permitted by applicable
law, be subject to any penalties provided by any Governmental Requirements for contracting for,
charging, taking, reserving or receiving interest in excess of the Maximum Amount).

     3.9 Interest Periods. When Borrower requests any Eurodollar Borrowing, Borrower may elect the
applicable interest period (each an "Interest Period"), which may be, at Borrower’s option, one
(1), two (2), three (3), or six (6) months, subject to the following conditions: (a) each Interest
Period applicable to any Eurodollar Borrowing commences on the day on or after the day when the
next preceding applicable Interest Period expires; (b) if any Interest Period for a Eurodollar
Borrowing begins on a day for which there exists no numerically corresponding Business Day in the
calendar month at the end of the Interest Period (“Ending Calendar Month”), then the Interest
Period ends on the next succeeding Business Day of the Ending Calendar Month, unless there is no
succeeding Business Day in the Ending Calendar Month in which case the Interest Period ends on the
next preceding Business Day of the Ending Calendar Month; (c) no Interest Period for any portion of
Principal Debt may extend beyond the scheduled repayment date for that portion of Principal Debt;
and (d) there may not be in effect at any one time more than five (5) Interest Periods.

     3.10 Conversions and Continuations. Borrower may (a) on the last day of the applicable
Interest Period (or at any other time, subject to payment of any Funding Loss) convert all or part
of a Eurodollar Borrowing to a Base Rate Borrowing, (b) at any time convert all or part of a Base
Rate Borrowing to a Eurodollar Borrowing, and (c) on the last day of an Interest Period, elect a
new Interest Period for a Eurodollar Borrowing; provided that no conversions to or elections of new
Interest Periods for any Eurodollar Borrowings shall be permitted while a Default exists unless the
Required Lenders otherwise consent in writing. Any such conversion is subject to the dollar limits
and denominations of Section 2.1 and may be accomplished by delivering a Borrowing Request to
Administrative Agent no later than 11:00 a.m. (i) on the third (3rd) Business Day before (A) the
conversion date for conversion to a Eurodollar Borrowing, and (B) the last day of the Interest
Period, for the election of a new Interest Period, and (ii) one (1) Business Day before the last
day of the Interest Period for conversion to a Base Rate Borrowing. Administrative Agent shall
notify each Lender of such continuation or conversion. Absent Borrower’s notice of conversion or
election of a new Interest Period, a Eurodollar Borrowing shall be automatically continued as a
Eurodollar Borrowing with a new Interest Period of one (1) month, with the expiration of such
Eurodollar Borrowing to occur on the first (1st) day of a calendar month; provided
however, if a Default exists, such Eurodollar Borrowing shall be automatically converted to a Base
Rate Borrowing.

21

 

     3.11 Order of Application

     (a) No Default. If no Default exists, then except as otherwise specifically provided in the
Loan Documents, any payment shall be applied to the Obligation in the order and manner as Borrower
directs.

     (b) Default. If a Default exists, any payment (including proceeds from the exercise of any
Rights) shall be applied in the following order: (i) to all fees and expenses for which any Credit
Party have not been paid or reimbursed in accordance with the Loan Documents (and if such payment
is less than all unpaid or unreimbursed fees and expenses, then the payment shall be paid against
unpaid and unreimbursed fees and expenses in the order of incurrence or due date); (ii) to accrued
interest on the Principal Debt; and (iii) to the remaining Obligation in the order and manner as
the Required Lenders deem appropriate.

     (c) Pro Rata. Each payment or prepayment shall be distributed to each Lender in accordance
with its Pro Rata Share of such payment or prepayment.

     3.12 Sharing of Payments, Etc. If any Lender obtains any amount (whether voluntary,
involuntary or otherwise) that exceeds the part of that payment that such Lender is then entitled
to receive under the Loan Documents, then such Lender shall purchase from the other Lenders
participations that will cause the purchasing Lender to share the excess amount ratably with each
other Lender. If all or any portion of any excess amount is subsequently recovered from the
purchasing Lender, then the purchase shall be rescinded and the purchase price restored to the
extent of the recovery. Borrower agrees that any Lender purchasing a participation from another
Lender under this Section may, to the fullest extent permitted by applicable law, exercise all of
its Rights of payment with respect to that participation as fully as if such Lender were the direct
creditor of Borrower in the amount of that participation.

     3.13 Booking Borrowings. To the extent permitted by applicable law, any Lender may make,
carry or transfer its Borrowings at, to, or for the account of any of its branch offices or the
office of any of its Affiliates. However, no Affiliate is entitled to receive any greater payment
under Section 3.15 than the transferor Lender would have been entitled to receive with respect to
those Borrowings, and a transfer may not be made if, as a direct result of it, Section 3.15 or 3.16
would apply to any of the Obligation. If any of the conditions of Sections 3.15 or 3.16 ever apply
to a Lender, then such Lender shall, to the extent possible, carry or transfer its Borrowings at,
to, or for the account of any of its branch offices or the office or branch of any of its
Affiliates so long as the transfer is consistent with the other provisions of this Section, does
not create any burden or adverse circumstance for such Lender that would not otherwise exist, and
eliminates or ameliorates the conditions of Sections 3.15 or 3.16 as applicable.

     3.14 Basis Unavailable or Inadequate for the Eurodollar Rate

     (a) Determination By Administrative Agent. If Administrative Agent determines that, for any
Eurodollar Borrowing, the basis for determining the applicable rate is not available, then
Administrative Agent shall promptly notify Borrower and Lenders of that determination (which is
conclusive and binding on Borrower absent manifest error), and all Borrowings shall bear interest
at the Base Rate plus the Applicable Margin. Until Administrative Agent notifies Borrower that
such circumstances no longer exist, Lenders’ commitments under this Agreement to make, or to
convert to, Eurodollar Borrowings shall be suspended.

     (b) Determination by a Lender. If any Lender determines that, for any Eurodollar Borrowing
and for other similar loans made by such Lender to similar borrowers, the resulting rate does
not accurately reflect the cost to such Lender of making or converting Borrowings at that rate
for the applicable Interest Period, then such Lender shall promptly notify
Administrative Agent and
Borrower, and all Borrowings of such Lender shall bear interest at the Base Rate plus the
Applicable Margin. Until

22

 

Administrative Agent notifies Borrower that such circumstances no longer exist, such Lender’s
commitment under this Agreement to make, or to convert to, Eurodollar Borrowings shall be
suspended.

     3.15 Additional Costs

     (a) Eurocurrency Reserves. If, after the date hereof, any Lender shall be required under any
Reserve Requirement to maintain reserves, then (i) such Lender (through Administrative Agent)
shall, within sixty (60) days after the end of any Interest Period with respect to any Eurodollar
Borrowing during which Lender was so required to maintain reserves, deliver to Borrower a
certificate stating (A) that such Lender was required to maintain reserves and as a result such
Lender incurred additional costs in connection with making Eurodollar Borrowings and (B) in
reasonable detail, such Lender’s computations of the amount of additional interest payable by
Borrower, pursuant to the provisions below, and (ii) Borrower shall, promptly upon receipt of any
such certificate, pay to Administrative Agent, for the account to such Lender, additional interest
on the unpaid principal amount of each Eurodollar Borrowing of such Lender made to it outstanding
during the Interest Period with respect to which the above-referenced certificate was delivered to
Administrative Agent, at a rate per annum equal to the difference obtained by subtracting (x) the
Eurodollar Rate for such Interest Period from (y) the rate obtained by dividing such Eurodollar
Rate by a percentage equal to 100% minus the Reserve Requirement of such Lender for such Interest
Period. The amount of interest payable by Borrower to any Lender as stated in any certificate
delivered to Administrative Agent pursuant to the provisions of this Section 3.15(a) shall be
conclusive and binding for all purposes, absent manifest error. The provisions of this Section
3.15(a) shall survive the termination of this Agreement.

     (b) Reserves. With respect to any Eurodollar Borrowing, if (i) any change in present
Governmental Requirement, any change in the interpretation or application of any present
Governmental Requirement, or any future Governmental Requirement imposes, modifies, or deems
applicable (or if compliance by any Lender with any such requirement of any Governmental Authority
results in) any such requirement that any reserves (including any marginal, emergency, supplemental
or special reserves) be maintained, and (ii) those reserves reduce any sums receivable by such
Lender under this Agreement or increase the costs incurred by such Lender in advancing or
maintaining any portion of any Eurodollar Borrowing, then (unless the effect is already reflected
in the rate of interest then applicable under this Agreement) such Lender (through Administrative
Agent) shall deliver to Borrower a certificate setting forth in reasonable detail the calculation
of the amount necessary to compensate it for its reduction or increase (which certificate is
conclusive and binding absent manifest error), and Borrower shall promptly pay that amount to such
Lender upon demand.

     (c) Capital Adequacy. With respect to any Borrowing and for similar loans to similar
borrowers, if any change in present Governmental Requirement or any future Governmental Requirement
regarding capital adequacy or compliance by Administrative Agent or any Lender (or any Person
controlling such Lender) with any request, directive or requirement now existing or hereafter
imposed by any Governmental Authority regarding capital adequacy, or any change in its written
policies or in the risk category of this transaction, reduces the rate of return on its capital as
a consequence of its obligations under this Agreement to a level below that which it otherwise
could have achieved (taking into consideration its policies with respect to capital adequacy) by an
amount deemed by it to be material (and it may, in determining the amount, use reasonable
assumptions and allocations of costs and expenses and use any reasonable averaging or attribution
method), then (unless the effect is already reflected in the rate of interest then applicable under
this Agreement) Administrative Agent or such Lender (through Administrative Agent) shall notify
Borrower and deliver to Borrower a certificate setting forth in
reasonable detail the calculation of the amount necessary to compensate it (which certificate
is conclusive and binding absent manifest error), and Borrower shall promptly pay that amount to
Administrative Agent or such Lender upon demand.

23

 

     (d) Taxes. Any Taxes payable by Administrative Agent or any Lender or ruled (by a
Governmental Authority) payable by Administrative Agent or any Lender in respect of this Agreement
or any other Loan Document shall, if permitted by Governmental Requirement, be paid by Borrower,
together with interest and penalties, if any (except for Taxes imposed on or measured by the
overall net income of Administrative Agent or such Lender). Administrative Agent or such Lender
(through Administrative Agent) shall notify Borrower and deliver to Borrower a certificate setting
forth in reasonable detail the calculation of the amount of payable Taxes, which certificate is
conclusive and binding (absent manifest error), and Borrower shall promptly pay that amount to
Administrative Agent for its account or the account of such Lender, as the case may be. If
Administrative Agent or such Lender subsequently receives a refund of the Taxes paid to it by
Borrower, then the recipient shall promptly pay the refund to Borrower.

     (e) Survival. The provisions of this Section 3.15 shall survive the satisfaction and payment
of the Obligation and termination of this Agreement.

     3.16 Change in Governmental Requirement. If any Governmental Requirement makes it unlawful
for any Lender to make or maintain Eurodollar Borrowings, then such Lender shall promptly notify
Borrower and Administrative Agent, and (a) as to undisbursed funds, that requested Borrowing shall
be made as a Base Rate Borrowing, and (b), as to any outstanding Borrowing, (i) if maintaining the
Borrowing until the last day of the applicable Interest Period is unlawful, the Borrowing shall be
converted to a Base Rate Borrowing as of the date of notice, and Borrower shall pay any related
Funding Loss, or (ii) if not prohibited by all Governmental Requirements, the Borrowing shall be
converted to a Base Rate Borrowing as of the last day of the applicable Interest Period, or (iii)
if any conversion will not resolve the unlawfulness, Borrower shall promptly prepay the Borrowing,
without penalty, together with any related Funding Loss.

     3.17 Funding Loss. borrower agrees to indemnify each lender against, and pay to it upon
demand, any funding loss of such lender When any Lender demands that Borrower pay any Funding
Loss, such Lender shall deliver to Borrower and Administrative Agent a certificate setting forth in
reasonable detail the basis for incurring Funding Loss and the calculation of the amount, which
calculation is conclusive and binding absent manifest error. The provisions of this Section 3.17
shall survive the satisfaction and payment of the Obligation and termination of this Agreement.

     3.18 Foreign Lenders. Each Lender that is organized under the Governmental Requirements of
any jurisdiction other than the United States of America or any State thereof (a) represents to
Administrative Agent and Borrower that (i) no Taxes are required to be withheld by Administrative
Agent or Borrower with respect to any payments to be made to it in respect of the Obligation, and
(ii) it has furnished to Administrative Agent and Borrower two (2) duly completed copies of U.S.
Internal Revenue Service Form W-8 BEN, Form W-8 ECI, Form W-8, or any other tax form acceptable to
Administrative Agent (wherein it claims entitlement to complete exemption from U.S. federal
withholding tax on all interest payments under the Loan Documents), and (b) covenants to (i)
provide Administrative Agent and Borrower a new tax form upon the expiration or obsolescence of any
previously delivered form according to Governmental Requirement, duly executed and completed by it,
and (ii) comply from time to time with all Governmental Requirements with regard to the withholding
tax exemption. If any of the foregoing is not true or the applicable forms are not provided and
such party is obligated by law to withhold, then Borrower or Administrative Agent (without
duplication) may deduct and withhold from interest payments under the Loan Documents United States
federal income tax at the
full rate applicable under the Code.

24

 

     3.19 Fees

     (a) Treatment of Fees. The fees described in this Section 3.19 (i) are not compensation for

366 days, as the case may be. The fees described in this Section 3.19 are in all events subject to
the provisions of Section 3.8.

Property.

25

 

     4.3 Guaranties

     (a) PPT Guaranty. Pursuant to the PPT Guaranty, PPT shall unconditionally guarantee in favor
of the Credit Parties the full payment and performance of the Obligation.

unconditionally guarantee in favor of the Credit Parties the full payment and performance of the
Obligation subject to Section 4.3(c).

     (c) Release of Specific Subsidiary Guarantors. If, as of any date, any Property owned by a
Subsidiary Guarantor is no longer an Unencumbered Property, then Administrative Agent shall, upon
the written request of Borrower, release such Subsidiary Guarantor from the Subsidiary Guaranty
pursuant to a release of guaranty in the form attached to the Subsidiary Guaranty, unless a Default
exists or would result from such release.

     4.4 Unencumbered Properties Held by Consolidated Affiliates. Notwithstanding anything
contained herein to the contrary, Unencumbered Properties may include Properties owned by a
Consolidated Affiliate of Borrower only if (a) Borrower or PPT owns or controls, directly or
indirectly, at least ninety five percent (95%) of the issued and outstanding Stock of such
Consolidated Affiliate free and clear of any Liens (other than Permitted Liens) or other
restrictions on the sale or pledge thereof, (b) a majority of the holders of the Stock of such
Consolidated Affiliate has the power to cause such Consolidated Affiliate to execute the Subsidiary
Guaranty, grant Liens in the Unencumbered Properties owned by such Consolidated Affiliate, and

SECTION 8

NEGATIVE COVENANTS

     Until the Obligation is paid in full, Borrower covenants and agrees as follows:

     8.1 Payment of Obligations. Borrower shall not, and shall not permit any Company to,
voluntarily prepay principal of, or interest on, any Liabilities other than the Obligation, if a
Default exists.

     8.2 Employee Plans. Except where a Material Adverse Event would not result, Borrower shall
not, and shall not permit any Company to, permit any of the events or circumstances described in
Section 6.10 to exist or occur.

     8.3 Transactions with Affiliates. Except as disclosed on Schedule 6.14 (as supplemented from
time to time to reflect changes as a result of transactions permitted by this Agreement or approved
by the Required Lenders), Borrower shall not, and shall not permit any Company to, enter into any
material transaction with any of its Affiliates, other than transactions in the ordinary course of
business and upon fair and reasonable terms not materially less favorable than it could obtain or
could become entitled to in an arm’s-length transaction with a Person that was not its Affiliate.

     8.4 Compliance with Governmental Requirements and Documents. Borrower shall not, and shall
not permit any Company to, (a) violate the provisions of any Governmental Requirements applicable
to it or of any material agreement to which it is a party if that violation alone, or when
aggregated with all other violations, could reasonably be expected to result in Material Adverse
Event, (b) violate the provisions of its Constituent Documents where such violation could result in
a Material Adverse Event, or (c) repeal, replace, or amend any provision of its Constituent
Documents if that action could reasonably be expected to result in a Material Adverse Event.

     8.5 Loans, Advances, and Investments. Without the prior written consent of the Required
Lenders, the Companies, on a Consolidated Basis, shall not have or make any investments in the
following, calculated, where applicable, after giving effect to the pertinent investment and using
values determined in accordance with the definition of Total Assets:

     (a) Properties consisting of raw land exceeding in the aggregate five percent (5%) of Total
Assets;

     (b) Properties under construction having actual and budgeted costs exceeding in the aggregate
twenty percent (20%) of Total Assets (including the total budgeted project costs for all Properties
under construction); provided that the Companies may not have Properties under construction that
are less than fifty percent (50%) pre-leased having actual and budgeted costs exceeding in the
aggregate fifteen percent (15%) of Total Assets (including the total budgeted project costs for all
Properties under construction);

Borrower) to Borrower or to PPT, (c) Distributions paid to the holders of PPT’s Stock who
simultaneously use the proceeds of such Distributions to purchase additional shares of PPT’s Stock
pursuant to a dividend reinvestment program, and (d) Special Dividends; provided that the amount of
any Distributions made pursuant to clauses (b) and (c) shall not be limited by clause (a). Nothing
in this Section 8.6 restricts the issuance by any Company of preferred Stock solely because such
Stock requires the payment of Distributions with respect to such Stock prior to the payment of
Distributions with respect to common Stock.

     8.7 Sale of Assets. Neither Borrower nor PPT shall sell, assign, lease, transfer, or
otherwise dispose of all or substantially all of its assets.

or consolidate with any other Person or liquidate, wind up, or dissolve (or suffer any liquidation
or dissolution); provided, however, that the foregoing shall not operate to prevent mergers or
consolidations of any Company into Borrower or another Company (if such transaction does not reduce
the net worth of the Companies determined in accordance with GAAP).

     8.9 Assignment. Borrower shall not, and shall not permit any Company to, assign or transfer
any of its Rights, duties, or obligations under any of the Loan Documents.

     8.10 Fiscal Year and Accounting Methods. Without the prior written consent of Administrative
Agent, Borrower shall not, and shall not permit any Company to, change its fiscal year or its
method of accounting (other than immaterial changes in methods or as required by GAAP).

type of business except the types of businesses in which they are presently engaged and any other
reasonably related business.

     8.12 Government Regulations. Borrower shall not, and shall not permit any Company to, conduct
its business in a way that it becomes regulated under the Investment Company Act of 1940, as
amended, or the Public Utility Holding Company Act of 1935, as amended.

     8.13 Amendment of Constituent Documents. Borrower shall not permit any amendment of any
Company’s Constituent Documents, if any, which would materially and adversely affect Administrative
Agent or Lenders or their respective Rights under the Loan Documents.

     8.14 Interest Rate Agreements. Borrower shall not permit the Companies’ Indebtedness that is
not either subject to a fixed interest rate or hedged pursuant to an Interest Rate Agreement
acceptable to Administrative Agent (“Variable Rate Debt”) to exceed twenty-five percent (25%) of
Total Assets;

37

 

provided that the Companies’ Variable Rate Debt may exceed twenty-five percent (25%) of Total
Assets for a period of time not to exceed ninety (90) days if Borrower is diligently seeking
Interest Rate Agreements with respect to such Indebtedness or is in the process of incurring fixed
rate Indebtedness or an Equity Issuance in order to comply with the requirements of this Section
8.14.

generally as they become due, (c) voluntarily seeks, consents to, or acquiesces in the benefit of
any Debtor Relief Law, or (d) becomes a party to or is made the subject of any proceeding provided

proceeding is involuntary, the applicable petition is dismissed within sixty (60) days after its
filing).

     10.4 Judgments and Attachments. Any Company fails, within sixty (60) days after entry, to
pay, bond, or otherwise discharge any judgment or order for the payment of money in excess of
$1,000,000 (individually or collectively) or any warrant of attachment, sequestration, or similar

SECTION 11

RIGHTS AND REMEDIES

     11.1 Remedies Upon Default

     (a) Debtor Relief. If a Default (i) occurs under Section 10.3(c) or (ii) occurs and is
continuing under Section 10.3(a), (b) or (d), the entire unpaid balance of the Obligation
automatically becomes due and payable without any action of any kind whatsoever.

     (b) Other Defaults. If a Default occurs and is continuing, subject to the terms of Section
13.9(b), then Administrative Agent may (and upon the request of the Required Lenders shall), do any
one or more of the following: (i) if the maturity of the Obligation has not already been
accelerated under Section 11.1(a), then declare the entire unpaid balance of all or any part of the
Obligation immediately due and payable, whereupon it is due and payable; (ii) reduce any claim to
judgment; and (iii) exercise any and all other legal or equitable Rights afforded by the Loan
Documents, the Governmental Requirements of the State of New York, or any other applicable
jurisdiction.

     11.2 Waivers. To the extent permitted by applicable law, each Company waives presentment and
demand for payment, protest, notice of intention to accelerate, notice of acceleration, and notice
of protest and nonpayment, and agrees that its liability with respect to all or any part of the
Obligation is not affected by any renewal or extension in the time of payment of all or any part of
the Obligation, by any indulgence, or by any release or change in any security for the payment of
all or any part of the Obligation.

     11.3 Performance by Administrative Agent. If any covenant, duty, or agreement of Borrower is
not performed in accordance with the terms of the Loan Documents, Administrative Agent may, while a
Default exists, at its option, perform, or attempt to perform that covenant, duty, or agreement on
behalf of Borrower (and any amount expended by Administrative Agent in its performance or attempted
performance is payable by Borrower to Administrative Agent on demand, becomes part of the
Obligation, and bears interest at the Default Rate from the date of Administrative Agent’s
expenditure until paid). However, neither Administrative Agent nor any Lender assumes or shall
have, except by its express written consent, any liability or responsibility for the performance of
any covenant, duty, or agreement of Borrower.

     11.4 Not in Control. None of the covenants or other provisions contained in any Loan Document
shall, or shall be deemed to, give Administrative Agent or Lenders the Right to exercise control
over the assets (including real property), affairs, or management of any Company.

     11.5 Course of Dealing. The acceptance by Administrative Agent or any Lender of any partial
payment on the Obligation shall not be deemed to be a waiver of any Default then existing. No
waiver by any Credit Party of any Default shall be deemed to be a waiver of any other then-existing
or subsequent Default. No delay or omission by any Credit Party in exercising any Right under the
Loan Documents will impair that Right or be construed as a waiver thereof or any acquiescence
therein, nor will any single or partial exercise of any Right preclude other or further exercise
thereof or the exercise of any other Right under the Loan Documents or otherwise.

     11.6 Cumulative Rights. All Rights available to the Credit Parties under the Loan Documents
are cumulative of and in addition to all other Rights granted to the Credit Parties at law or in
equity, whether or not the Obligation is due and payable and
whether or not Administrative Agent or

41

 

Lenders have instituted any suit for collection, foreclosure, or other action in connection with
the Loan Documents.

     11.7 Application of Proceeds. Any and all proceeds ever received by any Credit Party from the
exercise of any Rights pertaining to the Obligation shall be applied to the Obligation according to
Section 3.11.

     11.8 Certain Proceedings. Borrower shall promptly execute and deliver, or cause the execution
and delivery of, all applications, certificates, instruments, and all other documents and papers
Administrative Agent reasonably requests in connection with the obtaining of any consent, approval,
registration, qualification, permit, license, or authorization of any Governmental Authority or
other Person necessary or appropriate for the effective exercise of any Rights under the Loan
Documents. Because Borrower agrees that Administrative Agent’s and Lenders’ remedies at law for
failure of Borrower to comply with the provisions of this paragraph would be inadequate and that
failure would not be adequately compensable in damages, Borrower agrees that the covenants of this
Section 11.8 may be specifically enforced.

     12.1 Appointment, Powers and Immunities. Each Lender hereby irrevocably appoints and
authorizes Administrative Agent to act as its agent hereunder and under the other Loan Documents
with such powers as are specifically delegated to Administrative Agent by the terms of this
Agreement and of the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Administrative Agent (which term as used in this sentence and in Section 12.5
and the first sentence of Section 12.6 shall include reference to its Affiliates and its own and
its Affiliates’ officers, directors, employees, and agents):

     (a) shall have no duties or responsibilities except those expressly set forth in this
Agreement and in the other Loan Documents, and shall not by reason of this Agreement or any other
Loan Document be a trustee for any Lender;

     (b) shall not be responsible to Lenders for any recitals, statements, representations, or
warranties contained in this Agreement or in any other Loan Document, or in any certificate or
other document referred to or provided for in, or received by any of them under, this Agreement or
any other Loan Document, or for the value, validity, effectiveness, genuineness, enforceability, or
sufficiency of this Agreement, any Note, or any other Loan Document or any other document referred
to or provided for herein or therein, or for any failure by Borrower or any other Person to perform
any of its obligations hereunder or thereunder;

     (c) shall not be responsible to Lenders for any action taken or omitted to be taken by it
hereunder or under any other Loan Document or under any other document or instrument referred to or
provided for herein or therein or in connection herewith or therewith, except for its own gross
negligence or willful misconduct;

     (d) shall not, except to the extent expressly instructed by Required Lenders, be required to
initiate or conduct any litigation or collection proceedings hereunder or under any other Loan
Document; and

42

 

     (e) shall not be required to take any action which is contrary to this Agreement or any other
Loan Document or Governmental Requirement.

Administrative Agent may employ agents and attorneys-in-fact and shall not be responsible to
Lenders for the negligence or misconduct of any such agents or attorneys-in-fact selected by it in
good faith. Administrative Agent may deem and treat the payee of a Note as the holder thereof for
all purposes hereof unless and until a notice of the assignment or transfer thereof shall have been
filed with Administrative Agent, any such assignment or transfer to be subject to the provisions of
Section 13.11. Except to the extent expressly provided in Sections 12.8 and 12.10, the provisions
of this Section 12 are solely for the benefit of Administrative Agent and the Lenders, and Borrower
shall not have any rights as a third party beneficiary of any of the provisions hereof and Lenders
may modify or waive such provisions of this Section 12 in their sole and absolute discretion.

     12.2 Reliance by Administrative Agent. Administrative Agent shall be entitled to rely upon
any certification, notice, document, or other communication (including any thereof by telephone,
telecopy, telegram, or cable) reasonably believed by it to be genuine and correct and to have been
signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of
legal counsel, independent accountants, and other experts selected by Administrative Agent. As to
any matters not expressly provided for by this Agreement or any other Loan Document, Administrative
Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder or
thereunder in accordance with instructions given by Required Lenders, and such instructions of
Required Lenders and any action taken or failure to act pursuant thereto shall be binding on all
Lenders.

     12.3 Defaults.

     (a) Administrative Agent shall give Lenders notice of any material Default or Potential
Default of which Administrative Agent has knowledge or notice. Except with respect to (i) the
nonpayment of principal, interest, or any fees that are due and payable under the Loan Documents,
(ii) any Default or Potential Default with respect to which Administrative Agent has actually sent
written notice of to Borrower, and (iii) any Default or Potential Default with respect to which
Administrative Agent has entered into discussions with Borrower, Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of a Default or Potential Default unless
Administrative Agent has received notice from a Lender or Borrower specifying such Default or
Potential Default and stating that such notice is a “Notice of Default.” In the event that
Administrative Agent receives such a notice from Borrower or a Lender in accordance with the
immediately preceding sentence with respect to the occurrence of a material Default or Potential
Default, Administrative Agent shall give prompt notice thereof to Lenders. Within ten (10) days of
delivery of such notice of Default or Potential Default from Administrative Agent to Lenders (or
such shorter period of time as Administrative Agent determines is necessary), Administrative Agent
and Lenders shall consult with each other to determine a proposed course of action. Administrative
Agent shall (subject to Section 12.7) take such action with respect to such Default or Potential
Default as shall be directed by Required Lenders, provided that, (i) unless and until
Administrative Agent shall have received such directions, Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, including decisions (A) to
make protective advances that Administrative Agent determines are necessary to protect or maintain
any collateral and (B) to foreclose on any collateral or exercise any other remedy, with respect to
such Default or Potential Default as it shall deem advisable in the best interest of Lenders except
to the extent that this Agreement expressly requires that such action be taken, or not be taken,
only with the consent or upon the authorization of all Lenders, and (ii) no actions approved by
Required Lenders shall violate the Loan Documents or applicable Governmental Requirement.
Administrative Agent shall advise Lenders of all actions which Administrative Agent takes in
accordance with the provisions of this Section 12.3 and shall
continue to consult with Lenders with respect to all of such actions. Notwithstanding the
foregoing, if

43

 

Required Lenders shall at any time direct that a different or additional remedial
action be taken from that already undertaken by Administrative Agent, such different or additional
remedial action shall be taken in lieu of or in addition to, the prosecution of such action taken
by Administrative Agent; provided that all actions already taken by Administrative Agent pursuant
to this Section 12.3 shall be valid and binding on each Lender. All money (other than money
subject to the provisions of Section 12.3(f)) received from any enforcement actions, shall be
applied, first, to the payment or reimbursement of Administrative Agent and Lenders for expenses
incurred in accordance with the provisions of Sections 12.3(b), (c), and (d) and 12.5 and to the
payment of the administration fee to the extent not paid by Borrower pursuant to Section 3.19,
second, to the payment or reimbursement of Lenders for any advances made pursuant to Section
12.3(b); and third, to Lenders in accordance with their respective Pro Rata Share, unless an Unpaid
Amount is owed pursuant to Section 12.11, in which event such Unpaid Amount shall be deducted from
the portion of such proceeds of the Defaulting Lender and be applied to payment of such Unpaid
Amount to the Special Advance Lender.

     (b) All losses with respect to interest (including interest at the Default Rate) and other
sums payable pursuant to the Notes or incurred in connection with the Term Loans shall be borne by
Lenders in accordance with their respective Pro Rata Share. All losses incurred in connection with
the Term Loans, the enforcement thereof, or the realization of the security therefor, shall be
borne by Lenders in accordance with their respective Pro Rata Share, and Lenders shall promptly,
upon request, remit to Administrative Agent their respective Pro Rata Share of (i) any expenses
incurred by Administrative Agent in connection with any Default or Potential Default to the extent
any expenses have not been paid by Borrower, (ii) any advances made to pay taxes or insurance or
otherwise to preserve any Liens or to preserve and protect the collateral, whether or not the
amount is necessary, (iii) any other expenses incurred in connection with the enforcement of the
other Loan Documents, and (iv) any expenses incurred in connection with the consummation of the
Term Loans not paid or provided for by Borrower. To the extent any such advances are recovered in
connection with the enforcement of the other Loan Documents, each Lender shall be paid its Pro Rata
Share of such recovery after deduction of the expenses of Administrative Agent and Lenders.

     (c) In the event that, at the direction of Required Lenders or otherwise as provided in
Section 12.3(a), any action(s) is brought to collect on the Notes or any other Loan Document, such
action shall (to the extent permitted under applicable law and the decisions of the court in which
such action is brought) be an action brought by Administrative Agent and Lenders, collectively, to
collect on all or a portion of the Notes or enforce other Loan Document, and counsel selected by
Administrative Agent shall prosecute any such action on behalf of Administrative Agent and Lenders,
and Administrative Agent and Lenders shall consult and cooperate with each other in the prosecution
thereof. All decisions concerning the appointment of a receiver while such action and the
collection of any judgment entered in such action are pending, the conduct of such receivership,
the conduct of such action, the collection of any judgment entered in such action, and the
settlement of such action shall be made by Required Lenders, subject, however, to the provisions of
subsection (a) above. The costs and expenses of any such action shall be borne by the Lenders in
accordance with each of their respective Pro Rata Share.

     12.4 Rights as a Lender. With respect to its Term Loan, Eurohypo (and any successor acting
as Administrative Agent) in its capacity as a Lender hereunder shall have the same rights and
powers hereunder as any other Lender and may exercise the same as though it were not acting as
Administrative Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise
indicates, include Administrative Agent in its individual capacity. Subject to the provisions of
Section 3.12, Eurohypo (and any successor acting as Administrative Agent) and its affiliates may
(without having to account therefor to any other Lender) accept deposits from, lend money to, make
investments in, and generally engage in any kind of banking, investment banking, trust, or other
business with Borrower (and any of its affiliates) as if it were not acting as Administrative
Agent, and
Eurohypo (and any such successor) and any of its

44

 

affiliates may accept fees and other consideration from Borrower for services in connection with
this Agreement or otherwise without having to account for the same to Lenders.

     12.5 Indemnification. In performing its duties under the Loan Documents, Administrative
Agent will exercise the same degree of care as it normally exercises in connection with loans of a
similar type and size in which no syndication or participations are involved. Each Lender agrees
to indemnify Administrative Agent (to the extent not reimbursed by Borrower, but without limiting
the obligations of Borrower under Section 12.3) ratably in accordance with the aggregate principal
amount of the Term Loans held by Lenders, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or disbursements of any kind and
nature whatsoever that may be imposed on, incurred by, or asserted against Administrative Agent in
its capacity as Administrative Agent (including by any Lender) arising out of or by reason of any
investigation in or in any way relating to or arising out of this Agreement or any other Loan
Document or any other documents contemplated by or referred to herein or therein (including the
costs and expenses that Borrower is obligated to pay under Section 7.7, but excluding, unless a
Default has occurred and is continuing, normal administrative costs and expenses incident to the
performance of its agency duties hereunder) or the enforcement of any of the terms hereof or
thereof, provided that no Lender shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of Administrative Agent or a breach of the standard
of care set forth in the first sentence of this Section 12.5.

     12.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender agrees that it has,
independently and without reliance on the Administrative Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own credit analysis of each
Company and its decision to enter into this Agreement and that it will, independently and without
reliance upon Administrative Agent or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking
or not taking action under this Agreement or under any other Loan Document. Subject to the
provisions of Section 12.5, Administrative Agent shall not be required to keep itself informed as
to the performance or observance by any Company of this Agreement or any of the other Loan
Documents or any other document referred to or provided for herein or therein or to inspect the
assets or books of any Company. Except for notices, reports, and other documents and information
expressly required to be furnished to Lenders by Administrative Agent hereunder or under the other
Loan Documents, Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial condition, or
business of any Company (or any of their Affiliates) that may come into the possession of
Administrative Agent or any of its Affiliates.

     12.7 Failure to Act. Except for action expressly required of Administrative Agent hereunder
and under the other Loan Documents, Administrative Agent shall in all cases be fully justified in
failing or refusing to act hereunder and thereunder unless it shall receive further assurances to
its satisfaction from Lenders of their indemnification obligations under Section 12.5 against any
and all liability and expense that may be incurred by it by reason of taking or continuing to take
any such action.

     12.8 Resignation or Removal of Administrative Agent. Administrative Agent may resign at any
time by giving prior notice of at least thirty (30) days thereof to Lenders and Borrower and
Administrative Agent may be removed at any time with cause by Required Lenders. Upon any such
resignation or removal, Required Lenders shall have the right to appoint a successor Administrative
Agent that shall be an institutional lender that meets the qualifications of an Eligible Assignee,
which Borrower, as long as no Default exists,
shall then have the right to approve or disapprove in its reasonable discretion if such
successor Administrative Agent is not a Lender. If no successor Administrative Agent shall have
been so appointed by Required Lenders and shall have accepted such appointment within thirty (30)
days after the retiring Administrative Agent’s giving of notice of resignation of the retiring
Administrative Agent or Required Lenders’ removal of Administrative Agent, then the retiring

45

 

Administrative Agent may, on behalf of Lenders, appoint a successor Administrative Agent, that
shall meet the requirements of an Eligible Assignee. If no successor Administrative Agent has been
appointed by Required Lenders or Administrative Agent, as provided above, then the retiring
Administrative Agent’s resignation shall nevertheless become effective forty-five (45) days after
the retiring Administrative Agent’s notice of resignation and Required Lenders shall thereafter
perform all of the duties of Administrative Agent hereunder and/or under any other Loan Documents
until such time, if any, as the Required Lenders appoint a successor Administrative Agent, as
provided in this Section 12.8. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. The fees payable by Borrower to a successor Administrative Agent shall be
the same as those payable to its predecessor unless otherwise agreed between Borrower and such
successor. After any retiring Administrative Agent’s resignation hereunder as Administrative
Agent, the provisions of this Section 12 shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Administrative Agent.

     12.9 Consents under Loan Documents. Except as otherwise provided in the Loan Documents,
including Section 13.9, Administrative Agent may as expressly provided in the Loan Documents, or
otherwise with the prior consent of Required Lenders (but not otherwise), (a) grant any consent or
approval required of it or (b) consent to any modification or waiver under any of the Loan
Documents. If Administrative Agent solicits any consents or approvals from Lenders under any of
the Loan Documents, each Lender shall, within ten (10) Business Days of receiving such request,
give Administrative Agent written notice that it will grant such consent or approval or that it
will not grant such consent or approval; provided that, if any Lender does not respond within such
ten (10) Business Days, such Lender shall be deemed to have authorized Administrative Agent to vote
such Lender’s interest with respect to the matter which was the subject of Administrative Agent’s
solicitation as Administrative Agent elects. Any such solicitation by Administrative Agent for a
consent or approval shall be in writing and shall include a description of the matter or thing as
to which such consent or approval is requested and shall include Administrative Agent’s recommended
course of action or determination in respect thereof.

     12.10 Authorization. Administrative Agent is hereby authorized by Lenders to execute,
deliver, and perform in accordance with its terms each of the Loan Documents to which
Administrative Agent is or is intended to be a party and each Lender agrees to be bound by all of
the agreements of Administrative Agent contained in such Loan Documents. Borrower shall be
entitled to rely on all written agreements, approvals, and consents received from Administrative
Agent as being that also of Lenders, without obtaining separate acknowledgement or proof of
authorization of same.

     12.11 Defaulting Lenders. If any Lender (a “Defaulting Lender”) shall for any reason fail to
(i) make any respective Term Loan required pursuant to the terms of this Agreement or (ii) pay its
Pro Rata Share of an advance or disbursement to protect any Lien, any of the other Lenders may, but
shall not be obligated to, make all or a portion of the Defaulting Lender’s Term Loan or Pro Rata
Share of such advance, provided that such Lender gives Defaulting Lender and Administrative Agent
prior notice of its intention to do so. The right to make such advances in respect of Defaulting
Lender shall be exercisable first by the Lender holding the greatest Pro Rata Share of the Term
Loans and thereafter to each Lender in descending order of their respective Pro
Rata Shares of the Term Loans or in such other manner as Required Lenders (excluding
Defaulting Lender) may agree on. Whichever Lenders make all or any portion of the Defaulting
Lender’s proportionate share of the applicable Term Loan or advance in accordance with the
foregoing terms and conditions shall be referred to as a “Special Advance Lender.”

46

 

     (a) In any case where a Lender becomes a Special Advance Lender (i) the Special Advance
Lender shall be deemed to have purchased, and the Defaulting Lender shall be deemed to have sold, a
senior participation in the Defaulting Lender’s respective Term Loan to the extent of the amount so
advanced or disbursed (the “Advanced Amount”) bearing interest (including interest at the Default
Rate, if applicable) and (ii) the Defaulting Lender shall have no voting rights under this
Agreement or any other Loan Documents so long as it is a Defaulting Lender. It is expressly
understood and agreed that each of the respective obligations under this Agreement and the other
Loan Documents, including advancing Term Loans, losses incurred in connection with the Term Loans,
including costs and expenses of enforcement, and advances to preserve any Lien, shall be without
regard to any adjustment in the Pro Rata Shares occasioned by the acts of a Defaulting Lender. The
Special Advance Lender shall be entitled to an amount (the “Unpaid Amount”) equal to the applicable
Advanced Amount, plus any unpaid interest due and owing with respect thereto, less any repayments
thereof made by the Defaulting Lender immediately upon demand. The Defaulting Lender shall have
the right to repurchase the senior participation in its Term Loan from the Special Advance Lender
at any time by the payment of the Unpaid Amount.

     (b) A Special Advance Lender shall (i) give notice to the Defaulting Lender, Administrative
Agent, and each other Lender (provided that failure to deliver said notice to any party other than
the Defaulting Lender shall not constitute a default under this Agreement) of the Advance Amount
and the percentage of the Special Advance Lender’s senior participation in the Defaulting Lender’s
Term Loan and (ii) in the event of the repayment of any of the Unpaid Amount by the Defaulting
Lender, give notice to the Defaulting Lender and Administrative Agent of the fact that the Unpaid
Amount has been repaid (in whole or in part), the amount of such repayment and, if applicable, the
revised percentage of the Special Advance Lender’s senior participation. Provided that
Administrative Agent has received notice of such participation, Administrative Agent shall have the
same obligations to distribute interest, principal, and other sums received by Administrative Agent
with respect to a Special Advance Lender’s senior participation as Administrative Agent has with
respect to the distribution of interest, principal, and other sums under this Agreement; and at the
time of making any distributions to Lenders, shall make payments to the Special Advance Lender with
respect to a Special Advance Lender’s senior participation in the Defaulting Lender’s Term Loan out
of the Defaulting Lender’s share of any such distributions.

     (c) A Defaulting Lender shall immediately pay to a Special Advance Lender all sums of any kind
paid to or received by the Defaulting Lender from Borrower, whether pursuant to the terms of this
Agreement or the other Loan Documents, or in connection with the realization of the security
therefor, until the Unpaid Amount is fully repaid. Notwithstanding the fact that the Defaulting
Lender may temporarily hold such sums, the Defaulting Lender shall be deemed to hold same as a
trustee for the benefit of the Special Advance Lender, it being the express intention of Lenders
that the Special Advance Lender shall have an ownership interest in such sums to the extent of the
Unpaid Amount.

     (d) Each Defaulting Lender shall indemnify, defend, and hold Administrative Agent and each
other Lender harmless from and against any and all losses, damages, liabilities, or expenses
(including reasonable attorneys’ fees and expenses and interest at the Default Rate) which they may
sustain or incur by reason of the Defaulting Lender’s failure or refusal to abide by its
obligations under this Agreement or the other Loan Documents, except to the extent a Defaulting
Lender became a Defaulting Lender due to the gross negligence or willful misconduct of
Administrative Agent and/or any
Lender. Administrative Agent shall, after payment of any amounts due to any Special Advance Lender
pursuant to the terms of subsection (c) above, set-off against any payments due to such Defaulting
Lender for the claims of Administrative Agent and the other Lenders pursuant to this Indemnity.

47

 

     12.12 Other Agents.

     (a) Syndication Agent, in such capacity, shall have no rights, duties, or obligations
hereunder, except as specifically provided in this Agreement. Syndication Agent (a) may
voluntarily resign by notice to Administrative Agent, Lenders, and Borrower, and (b) shall resign
upon the request of the Required Lenders for cause. Upon the resignation of Syndication Agent, the
Required Lenders may elect to designate a successor Syndication Agent (which, if no Default or
Potential Default exists, is subject to Borrower’s approval that may not be unreasonably withheld),
which shall meet the requirements of an Eligible Assignee.

     (b) No Lender or other Persons identified on the facing page or signature pages of this
Agreement as a “syndication agent,” “documentation agent,” “co-documentation agent,” “book
manager,” “lead manager,” “arranger,” “book runner,” or “lead arranger” shall have any right,
power, obligation, liability, responsibility, or duty under this Agreement other than, in the case
of such Lenders, those applicable to all Lenders as such. Without limiting the foregoing, no
Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship
with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any
Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not
taking action hereunder.

SECTION 13

MISCELLANEOUS

     13.1 Headings. The headings, captions and arrangements used in any of the Loan Documents are,
unless specified otherwise, for convenience only and shall not be deemed to limit, amplify, or
modify the terms of the Loan Documents, nor affect the meaning thereof.

     13.2 Nonbusiness Days; Time. Any payment or action that is due under any Loan Document on a
non-Business Day may be delayed until the next-succeeding Business Day (but interest shall continue
to accrue on any applicable payment until payment is in fact made) unless the payment concerns a
Eurodollar Borrowing, in which case if the next-succeeding Business Day is in the next calendar
month, then such payment shall be made on the next-preceding Business Day.

     13.3 Communications. Unless otherwise specifically provided, whenever any Loan Document
requires or permits any consent, approval, notice, request, demand, or other communication from one
party to another, communication must be in writing (which may be by telex or telecopy) to be
effective and shall be deemed to have been given (a) if by telex, when transmitted to the
appropriate telex number and the appropriate answerback is received, (b) if by telecopy, when
transmitted to the appropriate telecopy number (and all communications sent by telecopy must be
confirmed promptly thereafter by telephone; but any requirement in this parenthetical shall not
affect the date when the telecopy shall be deemed to have been delivered), (c) if by mail, on the
fifth (5th) Business Day after it is enclosed in an envelope and properly addressed, stamped,
sealed, certified mail, return receipt requested, and deposited in the appropriate official postal
service, or (d) if by any other means, when actually delivered. Until changed by notice pursuant
to this Agreement, the address (and
telecopy number) for each party to a Loan Document is set forth on Schedule 1.

     13.4 Form and Number of Documents. The form, substance, and number of counterparts of each
writing to be furnished under this Agreement must be satisfactory to Administrative Agent and its
counsel.

48

 

     13.5 Survival. All covenants, agreements, undertakings, representations, and warranties made
in any of the Loan Documents survive all closings under the Loan Documents and, except as otherwise
indicated, are not affected by any investigation made by any party.

     13.6 Governing Law. EXCEPT AS EXPRESSLY PROVIDED IN A LOAN DOCUMENT, THE GOVERNMENTAL
REQUIREMENTS (OTHER THAN CONFLICT-OF-LAWS PROVISIONS) OF THE STATE OF NEW YORK AND OF THE UNITED
STATES OF AMERICA GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO THE LOAN DOCUMENTS AND THE
VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE LOAN DOCUMENTS.

     13.7 Invalid Provisions. Any provision in any Loan Document held to be illegal, invalid, or
unenforceable is fully severable; the appropriate Loan Document shall be construed and enforced as
if that provision had never been included; and the remaining provisions shall remain in full force
and effect and shall not be affected by the severed provision. Administrative Agent, Lenders, and
Borrower agree to negotiate, in good faith, the terms of a replacement provision as similar to the
severed provision as may be possible and be legal, valid and enforceable. However, if the
provision held to be illegal, invalid, or unenforceable is a material part of this Agreement, such
invalid, illegal, or unenforceable provision shall be, to the extent permitted by applicable law,
replaced by a clause or provision judicially construed and interpreted to be as similar in
substance and content to the original terms of such illegal, invalid, or unenforceable clause or
provision as the context thereof would reasonably allow, so that such clause or provision would
thereafter be legal, valid, and enforceable.

     13.8 Venue; Service of Process; Jury Trial. EACH PARTY TO ANY LOAN DOCUMENT, IN EACH CASE FOR
ITSELF, ITS SUCCESSORS AND ASSIGNS (AND IN THE CASE OF BORROWER, FOR EACH OF ITS CONSOLIDATED
AFFILIATES), (a) IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL
COURTS OF THE STATE OF NEW YORK, (b) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW,
ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY LITIGATION ARISING
OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE OBLIGATION BROUGHT IN DISTRICT COURTS OF
NEW YORK COUNTY, NEW YORK, OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW
YORK, (c) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY OF THE AFOREMENTIONED
COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, (d) IRREVOCABLY CONSENTS TO THE SERVICE OF
PROCESS OUT OF ANY OF THOSE COURTS IN ANY LITIGATION BY THE MAILING OF COPIES THEREOF BY CERTIFIED
MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND-DELIVERY, OR BY DELIVERY BY A NATIONALLY
RECOGNIZED COURIER SERVICE, AND SERVICE SHALL BE DEEMED COMPLETE UPON DELIVERY OF THE LEGAL PROCESS
AT ITS ADDRESS SET FORTH IN THIS AGREEMENT, (e) IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING
AGAINST ANY PARTY TO ANY LOAN DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS OR
THE OBLIGATION MAY BE BROUGHT IN ONE OF THE
AFOREMENTIONED COURTS, AND (f) IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW, ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY
LOAN DOCUMENT. The scope of each of the foregoing waivers is intended to be all-encompassing of
any and all disputes that may be filed in any court and that relate to the subject matter of this
transaction, including contract claims, tort claims, breach of duty claims, and all other common
law and statutory claims. Borrower (for itself and on behalf of each of its Consolidated
Affiliates) acknowledges that these waivers are a material inducement to Administrative Agent’s and
each Lender’s agreement to enter into a business relationship, that Administrative Agent and each
Lender has already relied on these waivers in entering into this Agreement, and that Administrative
Agent and each

49

 

Lender will continue to rely on each of these waivers in related future dealings. Borrower (for
itself and on behalf of each of its Consolidated Affiliates) further warrants and represents that
it has reviewed these waivers with its legal counsel, and that it knowingly and voluntarily agrees
to each waiver following consultation with legal counsel. THE WAIVERS IN THIS SECTION 13.8 ARE
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THESE WAIVERS
SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, SUPPLEMENTS, OR REPLACEMENTS TO OR OF THIS OR ANY OTHER
LOAN DOCUMENT. In the event of Litigation, this Agreement may be filed as a written consent to a
trial by the court.

     13.9 Amendments, Consents, Conflicts, and Waivers.

     (a) Required Lenders. Unless otherwise specifically provided, the provisions of this
Agreement may be amended, modified, or waived, only by an instrument in writing executed by
Borrower and the Required Lenders and supplemented only by documents delivered or to be delivered
in accordance with the express terms of this Agreement.

     (b) All Lenders. Except as specifically otherwise provided in this Section 13.9, any
amendment to or consent or waiver under this Agreement or any Loan Document that purports to
accomplish any of the following must be by an instrument in writing executed by Borrower and
executed (or approved, as the case may be) by each Lender (other than any Defaulting Lender): (i)
extends the scheduled Termination Date; (ii) extends the due date or decreases the amount of any
scheduled payment or amortization of the Obligation beyond the date specified in the Loan
Documents; (iii) decreases any rate or amount of interest, fees, principal, or other sums payable
to Administrative Agent or Lenders under this Agreement (except such reductions as are contemplated
by this Agreement); (iv) changes the definition of “Adjusted Property EBITDA,” “Approved Costs,”
EBITDA Adjustments,” “EBITDA Value,” “Occupancy Rate,” "Required Lenders,” “Pro Rata Share,” or
“Unencumbered Properties; (v) increases any one or more Lenders’ Term Loan; (vi) waives compliance
with, amends, or fully or partially releases any Obligor; (vii) permits any Obligor to assign any
of its rights under the Loan Documents; (viii) amends Section 4.1; or (ix) changes this Section
13.9(b) or any other matter specifically requiring the consent of all Lenders under this Agreement.

     (c) Administrative Agent. No amendment, modification, consent, or waiver which modifies the
rights, duties, or obligations of Administrative Agent shall be effective without the consent of
Administrative Agent.

     (d) Conflicts. Any conflict or ambiguity between the terms and provisions of this Agreement
and terms and provisions in any other Loan Document is controlled by the terms and provisions of
this Agreement.

     (e) Course of Dealing. No course of dealing or any failure or delay by any Credit Party or
any of its Representatives with respect to exercising any Right of any Credit Party under this
Agreement operates as a waiver thereof. A waiver must be in writing and signed by the Required
Lenders or Lenders, as appropriate, to be effective, and a waiver will be effective only in the
specific instance and for the specific purpose for which it is given.

     13.10 Multiple Counterparts. Any Loan Document may be executed in a number of identical
counterparts, each of which shall be deemed an original for all purposes and all of which
constitute, collectively, one agreement; but, in making proof of thereof, it shall not be necessary
to produce or account for more than one counterpart. Each Lender need not execute the same
counterpart of this Agreement so long as identical counterparts are executed by Borrower, each
Lender, and Administrative Agent. This Agreement shall become effective when counterparts of this
Agreement have been executed

50

 

and delivered to Administrative Agent by each Lender, Administrative Agent, and Borrower, or, in
the case only of Lenders, when Administrative Agent has received telecopied, telexed, or other
evidence satisfactory to it that each Lender has executed and is delivering to Administrative Agent
a counterpart of this Agreement.

     13.11 Successors and Assigns; Participations.

     (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, except that Borrower
may not assign or otherwise transfer any of its rights or obligations hereunder without the prior
written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or
obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of
subsection (b) of this Section 13.11, or (ii) by way of participation in accordance with the
provisions of subsection (d) of this Section 13.11 (and any other attempted assignment or transfer
by any party hereto shall be null and void). 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, Participants to the extent provided in subsection (d) of
this Section 13.11 and, to the extent expressly contemplated hereby, the Indemnitees) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

     (b) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of
its Rights and obligations under this Agreement (including all or a portion of its Term Loan and
Note at the time owing to it); provided that (i) except for an assignment by such Lender to an
Affiliate of such Lender, such Lender shall have received the prior consent of Administrative Agent
and, so long as no Default has occurred and is continuing, Borrower (each such consent not to be
unreasonably withheld or delayed); (ii) except in the case of an assignment of the entire remaining
amount of the assigning Lender’s Term Loan and Note at the time owing to it or in the case of an
assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender,
the aggregate amount of the Term Loan (which for this purpose includes Principal Debt outstanding
thereunder) subject to each such assignment, determined as of the date the Assignment and
Assumption with respect to such assignment is delivered to Administrative Agent or, if “Trade Date”
is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than
$5,000,000; (iii) 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 with respect to the Notes or
the Term Loan assigned; (iv) the parties to each assignment shall execute and deliver to
Administrative Agent an Assignment and Assumption, together with a processing and recordation fee
of $3,500; and (v) except in the case of an assignment of the entire remaining amount of the
assigning Lender’s Term Loan, the aggregate amount of the Term Loan of such assigning Lender, after
giving effect to such assignment, is at least $5,000,000. Subject to acceptance and recording
thereof by Administrative Agent pursuant to subsection (c) of this Section 13.11, from and after
the effective date
specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party
to this Agreement 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 3.15(c) and (d), 3.17, 7.7 and 7.12 with respect to facts and circumstances occurring
prior to the effective date of such assignment). Upon request, Borrower (at its expense) shall
execute and deliver a Note to the assignee Lender. Administrative Agent agrees to provide Borrower
with copies of all Assignment and Assumption Agreements so long as no Default exists. Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this subsection shall be treated for purposes of this Agreement as a sale by such

51

 

Lender of a participation in such rights and obligations in accordance with subsection (d) of this
Section 13.11.

     (c) Administrative Agent, acting solely for this purpose as an agent of Borrower, shall
maintain at Administrative Agent’s office 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 Term Loan of,
and principal amounts of the Notes owing to, each Lender pursuant to the terms hereof from time to
time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and
Borrower, Administrative Agent, and 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 Borrower
and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

     (d) Any Lender may at any time, sell participations to any Person (other than a natural
person or Borrower or any of Borrower’s Affiliates or Subsidiaries ) (each, a “Participant”) in all
or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a
portion of its Term Loan and/or the Notes; provided that (i) such Lender’s obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) Borrower, Administrative Agent, and
the other Lenders shall continue to deal solely and directly with such Lender in connection with
such Lender’s rights and obligations under this Agreement, (iv) the amount of each such
participation shall not be less than $5,000,000; and (v) the aggregate amount of the Term Loan of
such Lender selling such participation, after giving effect to such participation, is at least
$5,000,000. 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, waiver or other modification described in Section 13.9(b) that
directly affects such Participant. Subject to subsection (e) of this Section 13.11, Borrower
agrees that each Participant shall be entitled to the benefits of Sections 3.15(c) and (d) and 3.17
to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to
subsection (b) of this Section 13.11. To the extent permitted by law, each Participant also agrees
to be subject to Section 3.12 as though it were a Lender.

     (e) A Participant shall not be entitled to receive any greater payment under Sections 3.15(c)
and (d) than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 3.15(d) unless Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of Borrower, to
comply with Section 3.18 as
though it were a Lender.

     (f) Any Lender may at any time pledge or assign a security interest in all or any portion of
its Rights under this Agreement (including under its Note) to secure obligations of such Lender,
including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that
no such pledge or assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

otherwise consents in writing, Administrative Agent shall, at all times prior to its resignation or
replacement as Administrative Agent hereunder, retain a minimum Term Loan equal to the lesser of

     13.12 Discharge Only Upon Payment in Full; Reinstatement in Certain Circumstances. Borrower’s
obligations under the Loan Documents remain in full force and effect until the Obligation is paid
in full (except for provisions under the Loan Documents which by their terms expressly survive
payment of the Obligation and termination of the Loan Documents). If at any time any payment of
the principal of or interest on any Note or any other amount payable by Borrower or any other
obligor on the Obligation under any Loan Document is rescinded or must be restored or returned upon
the insolvency, bankruptcy, or reorganization of Borrower or otherwise, then the obligations of

payment had been due but not made at that time.

intended to, and does hereby, restate, renew, extend, amend, modify, supersede, and replace the
Original Agreement; (c) the Notes executed pursuant to this Agreement amend, renew, extend, modify,
replace, substitute for and supersede in their entirety (but do not extinguish, the Indebtedness
arising under) the promissory notes issued pursuant to the Original Agreement; and (d) the entering
into and performance of their respective obligations under this Agreement and the transactions
evidenced hereby do not constitute a novation

53
