 EXHIBIT 10.30 
  
 PREFERRED UNIT REDEMPTION AGREEMENT 
  
 This Preferred Unit Redemption Agreement (this “Agreement”) is made this 24th day of February, 2004, by and among Prentiss Properties Acquisition Partners, L.P., a Delaware limited partnership (the
“Partnership”), Belrose Realty Corporation (“Belrose”), Belmar Realty Corporation (“Belmar”), Belport Realty Corporation (“Belport”) and Belshire Realty
Corporation (“Belshire;” together with Belrose, Belmar and Belport, the “Sellers;” and each individually, a “Seller”). 
  
 RECITALS 
  
 A. Pursuant to that certain Contribution Agreement dated as of June 25, 1998 (the “Contribution
Agreement”), by and among the Partnership, Prentiss Properties Trust, a Maryland real estate investment trust (the “Company”) and Belair Capital Fund LLC (“Belair Fund”), Belair Fund
acquired 1,900,000 of the Partnership’s 8.30% Series B Cumulative Redeemable Perpetual Preferred Units (the “Series B Preferred Units”). 
  
 B. The Series B Preferred Units have been transferred to and among the Sellers (the “Transfers”),
but certificates reflecting all Transfers have not been issued. The certificates representing the Series B Preferred Units owned by the Sellers (the “Certificates”) currently held by the Sellers state that Belrose is the
holder of 386,464 Series B Preferred Units, Belmar is the holder of 963,536 Series B Preferred Units, Belport is the holder of 550,000 Series B Preferred Units and do not reflect any Series B Preferred Units as being held by Belshire. 
  
 C. As of the date of this Agreement after giving effect to all Transfers, as
reflected in the Third Amended and Restated Limited Partnership Agreement of the Partnership, dated as of October 1, 2001, as amended (the “Third Amended Agreement”), Belrose is the record holder of 386,464 Series B Preferred
Units, Belmar is the record holder of 663,536 Series B Preferred Units, Belport is the record holder of 390,000 Series B Preferred Units and Belshire is the record holder of 460,000 Series B Preferred Units. 
  
 D. The Partnership sent a notice of redemption pursuant to Section 4.02(d)(v)
of the Third Amended Agreement to the Sellers on January 21, 2004, which requires the Sellers sell their Series B Units to the Partnership. 
  
 E. The Sellers desire to sell to the Partnership and the Partnership desires to redeem from the Sellers the above-referenced Series B Preferred Units held
by the Sellers for the consideration and upon the terms and subject to the conditions hereinafter set forth. 
  
 NOW, THEREFORE, in consideration of the premises and the mutual agreements and obligations contained herein, the Sellers, the Partnership and the General
Partner each agrees as follows: 

 1. Purchase and Sale of the Series B Preferred Units.

referred to herein as the “Units”). 
  
 1.2 Closing. The closing of the transactions contemplated hereby (the “Closing”) shall take place at 10 a.m., eastern time, on February 24, 2004, at the offices of Akin Gump Strauss Hauer & Feld LLP,

 1.3 Redemption Price. The redemption price for each Unit will be

Company, (iii) the Certificate of Non-Foreign Status, a form of which is attached as Exhibit C, and (iv) the Cross Receipt in the form attached as Exhibit D. 
  
 (b) At the Closing, after receipt of the deliveries specified in Section 1.4(a), the Partnership shall deliver to each
Seller the Redemption Price for the Units being sold by such Seller by wire transfer of immediately available funds into an account or accounts designated by the Seller. 
  
 2. Representations and Warranties of the Sellers. Each Seller hereby represents and warrants to the Partnership as follows:

the Units by the Seller pursuant hereto have been duly authorized by all necessary corporate action. This Agreement and each other instrument or document to be executed in connection herewith shall, upon the execution and delivery thereof by the
Seller, constitute the legal, valid and binding obligations of the Seller enforceable against the Seller in accordance

 with the respective terms thereof, except as the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and general equitable principles. 
  
 (b) Proceedings. There are no actions, suits or legal, administrative, arbitration or other proceedings or governmental investigations pending or,
to the knowledge of the Seller, threatened against the Seller, which seek to question, delay or prevent the consummation of, or could materially impair the ability of the Seller to consummate, the transactions contemplated hereby. There are no
outstanding judgments, orders, writs, injunctions, indictments or information, grand jury subpoenas or civil investigative demands, plea agreements, stipulations, awards or decrees of any court, arbitrator or any federal, state, municipal or other

 (c) Title to Interests. At the Closing Date, (i) the Seller is the record and beneficial owner of the number of Units set forth opposite such
Seller’s name on Exhibit A, (ii) other than this Agreement, there are no outstanding subscriptions, options, warrants, rights, contracts, understandings or agreements to purchase or otherwise acquire the Units or the preferred shares
issuable upon exchange of the Units, (iii) the sale of the Units to the Partnership hereunder will transfer title to the Units free and clear of all liens, claims, charges or encumbrances whatsoever and (iv) the Sellers and their affiliates are not
in possession of any certificates representing the Units (other than the Certificates). The Seller acknowledges that the Partnership will amend the Third Amended Agreement to eliminate the Series B Preferred Units and that the Company will file
Articles Supplementary to the Amended and Restated Declaration of Trust of the Company to declassify the Company’s Series B Cumulative Redeemable Perpetual Preferred Shares immediately subsequent to the Closing. 
  
 (d) Brokers and Finders. The Seller has not employed any broker or
finder who will seek compensation from the Partnership and the Seller has not otherwise entered into any arrangement regarding the payment of any brokerage fees, commissions or finder’s fees in connection with the sale of the Units that will
result in any liability on the part of the Partnership. 
  
 (e)
Not a Foreign Person. The Seller is not a “foreign person” as defined in Section 1445(f)(3) of the Internal Revenue Code of 1986, as amended.

Agreement that were not fulfilled prior to the execution of this Agreement. 
  
 3.
Representations and Warranties of the Partnership. The Partnership hereby represents and warrants to each of the Sellers as follows: 
  
 (a) Existence and Authority Relative to Agreement. The Partnership is a limited partnership duly organized, validly existing and in good standing
under the laws of the State of Delaware. The Partnership has all necessary corporate power and authority to execute and deliver this Agreement and each other agreement, document or instrument to be executed or delivered in connection herewith and to
perform the obligations to be performed by the Partnership hereunder and thereunder. The execution, delivery and performance of this 
  

 3 

 Agreement by the Partnership have been duly authorized by all necessary partnership action. This Agreement and each other
instrument or document to be executed in connection herewith shall, upon the execution and delivery thereof by the Partnership, constitute the legal, valid and binding obligations of the Partnership enforceable against the Partnership in accordance
with the respective terms thereof, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and general
equitable principles. 
  
 (b) Proceedings. There are no
actions, suits or legal, administrative, arbitration or other proceedings or governmental investigations pending or, to the knowledge of the Partnership, threatened against the Partnership, which seek to question, delay or prevent the consummation
of, or could materially impair the ability of the Partnership to consummate, the transactions contemplated hereby. There are no outstanding judgments, orders, writs, injunctions, indictments or information, grand jury subpoenas or civil
investigative demands, plea agreements, stipulations, awards or decrees of any court, arbitrator or any federal, state, municipal or other governmental department, commission, board, agency or instrumentality against or relating to Partnership or,
to the knowledge of the Partnership, the Units. 
  
 (c) Brokers
and Finders. The Partnership has not employed any broker or finder who will seek compensation from the Seller and the Partnership has not otherwise entered into any arrangement regarding the payment of any brokerage fees, commissions or
finder’s fees in connection with the sale of the Units that will result in any liability on the part of the Seller. 
  
 4. General. 
  
 4.1 The Sellers’ Access to Information. Each Seller acknowledges that it has had access to all publicly available information relating to the Company, the General Partner and the Partnership (including the
Third Amended Agreement) which is all of the information that it considers necessary to evaluate the merits and risks of its sale of the Units. Sellers’ prior knowledge and experience in financial and business matters enables them to make an
informed decision with respect to a sale of the Units to Partnership. The Sellers have relied upon their own tax, legal and financial advisors with regard to all matters relating to their sale of the Units and not on any advice, recommendation, act
or failure to act of the Partnership, the General Partner, the Company or any of their respective affiliates. In connection with the redemption of the Units by the Partnership, the Sellers have independently determined an acceptable price for the
Units, and the Redemption Price is based upon such independent determination.

 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 
  

 7 

 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.

  
 “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. 
  

 8 

 “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: 
  

							
	 Index Ratio  

	  	 Applicable Margin

	  	1.25	%	 	0	%
	 Less than 0.35 to 1.0
	  	1.125	%	 	0	%

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 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:

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

 SECTION 2 
  

COMMITMENT 
  
 2.1 Revolving Facility. Subject to the provisions in the Loan Documents, each Lender severally and not jointly agrees to lend to Borrower one or
more Borrowings hereunder which Borrower may borrow, repay, and reborrow under this Agreement, subject to the following conditions: 
  
 (a) each Borrowing requested by Borrower hereunder must occur on a Business Day and no later than the Business Day immediately preceding the
Termination Date; 
  
 (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 a greater integral multiple of $100,000 or, if less, the Unused Commitment; 
  
 (c) the Total Principal Debt 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) $20,000,000, 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). 
  
 (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 Chicago, Illinois at 12:00 noon on such Borrowing Date. 
  
 (c) Upon the occurrence of a Default or if any Swing Line Loan shall be outstanding for more than fourteen (14) Business Days, 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 
  

 27 

 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 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. 
  
  

 28 

 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 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 Chicago, Illinois 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 Lenders. Once terminated, the Total Commitment may not be increased or reinstated. 
  
 2.5 Lenders; Increase in Total Commitment. 
  
 (a) The Lenders on the Closing Date shall be the Lenders set forth on Schedule 1. 
  

 29 

 (b) After the Closing Date, Administrative Agent may, from time to time 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 $400,000,000 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;

  
 (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. 
  

 30 

 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. 
  

(b) Borrower must make each payment and prepayment on the Obligation, without offset, counterclaim, or deduction, to Administrative Agent’s
principal office in Chicago, Illinois, 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 March 1, 2004, and on the Termination Date. 
  
 (b) Principal Payments. The Total Principal Debt (other than under the
Swing Line Subfacility) 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; 
  

 31 

 (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. 
  
 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 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. 
  

 32 

 (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. 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). 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 §
303.001, as amended, as limited by Texas Finance Code § 303.305. 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 five (5) 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. 
  

 33 

 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 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; and (iv) 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. 
  

 34 

 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 with respect
to liabilities or assets consisting of or including Eurocurrency Liabilities, 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 
  

 35 

 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. 
  

 36 

 (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
3.19 (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. 
  

 37 

 (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% but less than the Total Commitment times 66 2/3%
	  	0.175	%
	 Equal to or greater than the Total Commitment times 66 2/3%
	  	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 March 31, 2004, 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 the Applicable Margin is determined by reference to the Applicable 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 first date on which the Applicable Margin is determined by reference to the Applicable 
  

 38 

 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 Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was
in effect. 
  
 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. 
  
 SECTION 4 
  
 UNENCUMBERED PROPERTIES; GUARANTIES 
  
 4.1 Unencumbered Properties. Borrower shall not permit, as of any date, the ratio of the Unsecured Debt of the Companies on a Consolidated Basis to
the Unencumbered Property Value of all Unencumbered Properties to exceed 0.55 to 1.0. For purposes of the foregoing, “Unencumbered Property Value” means, as of any determination date, the sum of (without duplication)
the Companies’ Share of: 
  
 (a) the EBITDA Value of
each Unencumbered Property owned by Borrower or a Subsidiary Guarantor for, and in which construction was completed and a certificate of occupancy was issued, more than twelve (12) months prior to such determination date; plus 
  
 (b) the EBITDA Value of each Unencumbered Property owned by Borrower
or a Subsidiary Guarantor for, and in which construction was completed by a Company and a certificate of occupancy was issued, less than twelve (12) months prior to such determination date and that has an Occupancy Rate of at least eighty-five
percent (85%) for three (3) consecutive months; plus 
  
 (c) the Approved Costs of each Unencumbered Property not included in (a) and (b) above. 
  
 Notwithstanding the foregoing, Unencumbered Property Value shall be limited as follows: 
  

 39 

 (i) the aggregate amount of Approved Costs included in the calculation of
Unencumbered Property Value attributable to (x) Unencumbered Properties under construction and (y) Unencumbered Properties owned by Borrower or a Subsidiary Guarantor for, or in which construction work was completed and a certificate of occupancy
was issued, less than twelve (12) months prior to the date of determination and that have Occupancy Rates of less than eighty-five percent (85%), shall not exceed the lesser of (A) $90,000,000, and (B) fifteen percent (15%) of Unencumbered
Property Value; 
  
 (ii) the amount of
Approved Costs or EBITDA Value, as the case may be, included in the calculation of Unencumbered Property Value attributable to any single Unencumbered Property shall not exceed twenty percent (20%) of Unencumbered Property Value; 
  
 (iii) if any Company that owns any Unencumbered
Property described above has any minority interests, then Unencumbered Property Value shall be adjusted to exclude the minority interests’ Share of such Unencumbered Property. 
  
 As of the Closing Date, the Unencumbered Properties consist of the Unencumbered Properties listed on Schedule
4.1. No Unencumbered Property can have a value, calculated as provided above, of less than $0.00. 
  
 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 form attached to the Subsidiary Guaranty, each Company
that owns an Unencumbered Property shall unconditionally guarantee in favor of the Credit Parties the full payment and performance of the Obligation subject to the last two sentences of Section 4.4. 
  
 (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 
  

 40 

 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 Consolidated Affiliate has not (i) created, incurred, assumed,
guaranteed, or suffered to exist any 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, (E) the guaranty of the obligations of Borrower pursuant to Recourse Debt of Borrower permitted under Section 9.4, and (F) equipment leases incurred in the ordinary course of business, (d) such
Consolidated Affiliate has not created, incurred, or suffered 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.

 SECTION 6 
  
 REPRESENTATIONS AND WARRANTIES 
  
 Borrower represents and warrants to the Credit Parties as follows:

 55 

 10.6 Misrepresentation. Any material representation or warranty made by any Company contained in
any Loan Document at any time proves to have been incorrect in any material respect when made and such misrepresentation shall continue for thirty (30) days after the earlier to occur of the date (a) Borrower knows of, or (b) Borrower receives
notice from Administrative Agent of, such misrepresentation.

 10.8 Validity and Enforceability
of Loan Documents. Except in accordance with its terms or as otherwise expressly permitted by this Agreement, any Loan Document at any time after its execution and delivery ceases to be in full force and effect in any material respect or is
declared by a Governmental Authority to be null and void or its validity or enforceability is contested by any Company, or any Company denies that it has any further liability or obligations under any Loan Document to which it is a party.

(12) consecutive calendar months, individuals who were directors or trustees of PPT on the first day of such period shall cease to constitute a majority of the board of directors of PPT; provided, however, that the directors or trustees of

 56 

 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 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, upon the request of the Required Lenders, may 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 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. 
  

 57 

 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. Bank One, NA 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 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 Illinois 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. 
  

 58 

 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, 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. 
  

 59 

 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, 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 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 
  

 60 

 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 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 
  

 61 

 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 the Majority Lenders or 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. 
  

 62 

 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 Schedule1. 
  
 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. 
  

 63 

 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 TEXAS, (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 DALLAS COUNTY, TEXAS,
OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS, DALLAS DIVISION, (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 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. 
  

 64 

 (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 (x) increase the amount or amend the definition of Permitted Redemptions must be by an instrument in writing executed by Borrower and the Majority Lenders,
and (y) 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 Agents
or Lenders under this Agreement (except such reductions as are contemplated by this Agreement); (iv) changes the definition of “Majority Lenders” or “Required Lenders,” (v) increases the amount of the Total
Commitment; (vi) waives compliance with, amends, or fully or partially releases the PPT Guaranty; (vii) permits Borrower to assign any of its rights hereunder; (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.

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. 
  
 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 

 

 65 

 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, (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 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 shall have received the prior consent of each
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
Commitment 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 Commitment (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 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. 
  

 66 

 (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 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. 
  

 67 

 (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). 
  
 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 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. 
  

 68 

 13.14 Restatement of Amended and Restated 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 Amended and Restated Agreement); (b) this Agreement is intended to, and does hereby, restate, renew, extend, amend, modify, supersede, and replace the Amended and Restated 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 Amended
and Restated 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.
