	 	(a)	the 361st day after a Major Asset Sale, to the extent Net Proceeds other than Special Excess Proceeds are received by the Parent or any of its Restricted Subsidiaries, and provided

 5 

	 	 (b)
	 the 30th day after
a Major Asset Sale, to the extent Special Excess Proceeds are received by the Parent or any of its Restricted Subsidiaries in connection therewith, the Company will make an Asset Sale Offer to all Holders of Notes, and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of
Notes and such other pari-passu Indebtedness that may be purchased out of such Special Excess Proceeds. 

 The offer
price in any such Asset Sale Offer will be equal to 106.375% of principal amount (if such Asset Sale Offer is made prior to June 1, 2011), 103.188% of principal amount (if such Asset Sale Offer is made on or after June 1, 2011 and prior to

the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement, and will be payable in cash. 
 (3) If any Major Asset Sale Excess Proceeds remain after consummation of such an Asset Sale Offer, the Parent and its Restricted Subsidiaries may use those Major Asset Sale Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. 
 (4) If the aggregate principal amount of Notes and other pari-passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Major Asset Sale Excess Proceeds, the Trustee will select the Notes and such other pari-passu Indebtedness to be purchased on a pro-rata basis. 
  

 6 

 (5) Pending the final application of any such Major Asset Sale Excess Proceeds, the
Parent or any of its Restricted Subsidiaries may temporarily reduce revolving credit borrowings under the Credit Agreement or, if such revolving credit borrowings have been reduced to zero, otherwise invest the Net Proceeds in Cash Equivalents in
any manner that is not prohibited by this Indenture. 
 (6) Prior to making any such Asset Sale Offer, the Parent or any such
Restricted Subsidiary may also apply all or any part of such Major Asset Sale Excess Proceeds to repay, redeem or repurchase Senior Debt under Credit Facilities; provided that if such Senior Debt is revolving credit Indebtedness, the
commitments with respect thereto must be correspondingly reduced and in such event the portion of such Major Asset Sale Excess Proceeds required to be used to make such Asset Sale Offer shall be correspondingly reduced. 
 Section 2.5 Payments for Consent. The Indenture is hereby amended by deleting Section 4.16 in its entirety. The Holders
hereby waive any past or present breach or failure to comply with the provisions of Section 4.16 of the Indenture by the Parent or any of its Subsidiaries.

		  	17	  	CREDIT AGREEMENT

 
immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Loans have been neither met nor
waived as provided herein, Administrative Agent shall promptly make such Loans available to Borrower. The failure of any Lender to make any new Loan to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any,
to make its new Loan, but no Lender shall be responsible for the failure of any other Lender to make any new Loan to be made by such other Lender. 
 Section 2.3. Use of Proceeds. Borrower shall use all Loans to (a) make the payments described in Schedule 4, (b) acquire Oil and Gas Properties in the current areas of the Restricted Persons’ operations, and
(c) finance capital expenditures related to such Oil and Gas Properties and to the Oil and Gas Properties that the Restricted Persons own on the Closing Date. In no event shall the funds from any Loan be used directly or indirectly by any
Person for personal, family, household or agricultural purposes or for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any “margin stock” (as such term is defined in Regulation U promulgated by
the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock. Borrower represents and warrants that Borrower is not engaged principally, or

 (b) Interest Payment Dates. On each Interest Payment Date, Borrower shall pay all interest then accrued on the Loans in immediately available
funds. 
 Section 2.5. Optional Prepayments. Borrower may prepay the Loans at any time and from time to time, in whole or in
part, upon no less than five (5) days’ and no more than sixty (60) days’ prior written notice to Administrative Agent of such prepayment, which such notice shall include the amount of such prepayment and the date on which such
prepayment shall be made. Upon the giving of any such notice, the principal amount of the Loans specified in such notice shall become due and payable on the date specified therein. All prepayments hereunder shall be in an aggregate minimum amount of
$1,000,000 and integral multiples of $100,000 in excess of that amount and shall be accompanied by the applicable Prepayment Premium (if any) described in Section 2.6. Each prepayment of principal under this section shall be accompanied by all
interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of
such prepayment. 
 Section 2.6. Prepayment Premium. Any principal amount of the Loans prepaid prior to the Maturity Date shall
be accompanied by a prepayment premium equal to the product of the principal amount so prepaid times the percentage set forth in the following table opposite the same time period in which such prepayment occurs (the “Prepayment
Premium”): 
  

				
	 Time Period
	  	Percentage

2010, the Prepayment Premium will be 5%. 
 Section 2.7. Obligations of Lenders Several. The obligations of the Lenders hereunder
to make Loans and to make payments pursuant to Section 2.2 are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 10.4(b) on any date required hereunder
shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its committed Loan, to purchase its participation or to make its payment
under Section 10.4(b). 
 Section 2.8. Letters in Lieu of Transfer Orders or Division Orders. Administrative Agent agrees
that it will not instruct Collateral Agent to send any of the letters in lieu of transfer or division orders provided pursuant to the provisions of Section 6.7 to the addressees thereof unless an Event of Default has occurred and is continuing,
at which time Administrative Agent may, at its option and in addition to the exercise of any of its other rights and remedies, instruct Collateral Agent to send any or all of such letters. 
 Section 2.9. Power of Attorney. Borrower hereby designates Administrative Agent as its agent and attorney-in-fact, to act in its name, place,
and stead solely for the purpose of completing and, upon the occurrence and the continuance of an Event of Default, delivering any and all of the letters in lieu of transfer or division orders delivered by Borrower pursuant to the provisions of
Section 6.7, including completing any blanks contained in such letters and attaching exhibits thereto describing the relevant Collateral. Borrower hereby ratifies and confirms all that Administrative Agent shall lawfully do or cause to be done
by virtue of this power of attorney and the rights granted with respect to such power of attorney. This power of attorney is coupled with the interests of Administrative Agent in the Collateral, shall commence and be in full force and effect as of
the Closing Date and shall remain in full force and effect and shall be irrevocable so long as any Obligation remains outstanding or unpaid or any Commitment exists. The powers conferred on Administrative Agent by this appointment are solely to
protect the interests of Administrative Agent, Collateral Agent, Lenders and any other Secured Creditors under the Loan Documents with respect to the assignment of production proceeds under certain of the Security Documents and shall not impose any
duty upon Administrative Agent to exercise any such powers. The power of attorney under this Section 2.9 is expressly limited to the rights and powers set forth herein and no additional rights or powers are herein created or implied.
Administrative Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and shall not be responsible to Borrower or any other Person for any act or failure to act with respect to such powers,
except for gross negligence or willful misconduct.

 Section 2.10. Security Interest in Accounts; Right of Offset. As security for the payment and
performance of the Obligations, Borrower hereby transfers, assigns, and pledges to Administrative Agent and each Lender (for the pro rata benefit of such Persons) and grants to Administrative Agent and each Lender (for the pro rata benefit of such
Persons) a security interest in all of its funds now or hereafter or from time to time on deposit with or in the custody of Administrative Agent or such Lender, with such interest of Administrative Agent and the Lenders to be retransferred,
reassigned, and/or released at the expense of Borrower upon payment in full and complete performance of all outstanding Obligations. All remedies as secured party or assignee of such funds shall be exercisable upon the occurrence of any Event of
Default, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof. Furthermore, Borrower
hereby grants to Administrative Agent and each Lender (for the pro rata benefit of such Persons) the right, exercisable at such time as any Obligation shall mature, whether by acceleration of maturity or otherwise, of offset or banker’s lien
against all of its funds now or hereafter or from time to time on deposit with Administrative Agent or such Lender, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any
withdrawal of funds deposited in a time deposit account prior to the maturity thereof. 
 Section 2.11. Change of Control
Prepayment. Should there occur a Change of Control, then, immediately and without notice (a) all Obligations under the Loan Documents shall automatically become immediately due and payable, without presentment, demand, protest, notice of
protest, default, or dishonor, notice of intent to accelerate maturity, notice of acceleration of maturity, or other notice of any kind, all of which are hereby expressly waived by the Restricted Persons, and (b) the Commitments, if any, shall

received by Administrative Agent not later than 1:00 p.m., Wayzata, Minnesota time, on the date such payment becomes due and payable. Any payment received by Administrative Agent after such time will be deemed to have been made on the next following

interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. When Administrative Agent collects or receives money on account of the Obligations, Administrative Agent

if so specified by Borrower;

Agent pro rata to each Lender Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection; provided that if any Lender then owes payments to Administrative
Agent under Section 10.4(b), any amounts otherwise distributable under this section to such Lender shall be deemed to belong to or Administrative Agent to the extent of such unpaid payments, and Administrative Agent shall apply such amounts to
make such unpaid payments rather than distribute such amounts to such Lender.

reduction suffered.

office of such Lender or such Lender’s holding company, if any, regarding capital requirements has the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a
consequence of this Agreement, the Commitments of such Lender or the Loans made by such Lender to a level

documentation prescribed by applicable law or reasonably requested by Borrower or Administrative Agent as will enable Borrower or Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting
requirements. 
 Without limiting the generality of the foregoing, in the event that Borrower is resident for tax purposes in the United
States of America, any Foreign Lender shall deliver to Borrower and Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement

to the extent of indemnity payments made, or additional amounts paid, by Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Lender and without interest (other
than any interest paid by the relevant Governmental Authority with respect to such refund), provided that Borrower, upon the request of such Lender agrees to repay the amount paid over to Borrower (plus any penalties, interest or other
charges imposed by the relevant Governmental Authority) to such Lender in the event such Lender is required to repay such refund to such Governmental Authority. This subsection shall not be construed to require Administrative Agent or any Lender to
make available its tax returns (or any other information relating to its taxes that it deems confidential) to Borrower or any other Person. 
 Section 3.4. Payments by Borrower; Presumptions by Administrative Agent. Unless Administrative Agent shall have received notice from Borrower prior to the date on which any payment is due to Administrative Agent for the account

are in full force and effect in all material respects, (b) all material rents, royalties and other payments due and payable by any Restricted Person or, to Borrower’s knowledge, any other Person under such leases, contracts, servitudes and
other agreements, or under any Permitted Liens, or otherwise attendant to the ownership or operation of any Oil and Gas Properties, have been properly and timely paid, and (c) no Restricted Person is in default with respect to its obligations
(and no Restricted Person has knowledge of any default by any third party with respect to such third party’s obligations) under any such leases, contracts, servitudes and other agreements, or under any Permitted Liens, or otherwise attendant to
the ownership or operation of any part of the Oil and Gas Properties, where such default could adversely affect the ownership or operation of such Oil and Gas Properties. No Restricted Person is currently accounting for any royalties, or overriding
royalties or other payments out of production, on a basis (other than delivery in kind) less favorable to such Restricted Person than proceeds received by such Restricted Person (calculated at the well) from sale of production, and no Restricted
Person has any liability (or alleged liability) to account for the same on any such less favorable basis. As used in this Section, “Oil and Gas Properties” means Oil and Gas Properties to which Proved Reserves of the Restricted Persons in
Texas are properly attributed. 
 Section 5.29. Sale of Production. Except as set forth in the Disclosure Schedule, no Oil and
Gas Property is subject to any contractual or other arrangement (i) which permits payment for production to be deferred for a substantial period after the month in which such production is delivered (in the case of oil, not in excess of 60
days, and in the case of gas, not in excess of 90 days) or (ii) whereby payments are made to a Restricted Person other than by checks, drafts, wire transfer advises or other similar writings, instruments or communications for the immediate
payment of money. Except for production sales contracts, processing agreements, transportation agreements and other agreements relating to the marketing of production that are listed on the Disclosure Schedule in connection with the Oil and Gas
Properties to which such contract or agreement relates: (i) no Oil and Gas Property is subject to any contractual or other arrangement for the sale, processing or transportation of production (or otherwise related to the marketing of
production) which cannot be canceled on 120 days’ (or less) notice without a customary 

  

					
		  	33	  	CREDIT AGREEMENT

 
breakage fee and (ii) all contractual or other arrangements for the sale, processing or transportation of production (or otherwise related to the
marketing of production) from any Oil and Gas Property to which any Restricted Person is a party or, to Borrower’s knowledge otherwise, are bona fide arm’s length transactions made on the best terms available with third parties not
affiliated with Restricted Persons. Each Restricted Person is presently receiving a price for all production from (or attributable to) each Oil and Gas Property that is subject to a production sales contract or marketing contract listed on the
Disclosure Schedule that is computed in accordance with the terms of such contract, and no Restricted Person is having deliveries of production from such Oil and Gas Property curtailed substantially below such property’s delivery capacity.
Except as set forth in the Disclosure Schedule, no Restricted Person, nor any Restricted Person’s predecessors in title, has received prepayments (including payments for gas not taken pursuant to “take or pay” or other similar
arrangements) for any oil, gas or other hydrocarbons produced or to be produced from any Oil and Gas Properties after the date hereof. Except as in Section 5.29 of the Disclosure Schedule, there is no Oil and Gas Property with respect to which
any Restricted Person, or any Restricted Person’s predecessors in title, has, prior to the date hereof, taken more (“overproduced”), or less (“underproduced”), gas from the lands covered thereby (or pooled or unitized
therewith) than its ownership interest in such Oil and Gas Property would entitle it to take; and Section 5.29 of the Disclosure Schedule accurately reflects, for each well or unit with respect to which such an imbalance is shown thereon to
exist, (i) whether such Restricted Person is overproduced or underproduced and (ii) the volumes (in cubic feet or British thermal units) of such overproduction or underproduction and the effective date of such information. Except as set
forth in the Disclosure Schedule, no Oil and Gas Property is subject to a gas balancing arrangement under which one or more third parties may take a portion of the production attributable to such Oil and Gas Property without payment (or without full
payment) therefor as a result of production having been taken from, or as a result of other actions or inactions with respect to, other properties. No Oil and Gas Property is subject at the present time to any regulatory refund obligation and, to
the best of Restricted Person’s knowledge, no facts exist which might cause the same to be imposed. As used in this Section, “Oil and Gas Properties” means Oil and Gas Properties to which Proved Reserves of the Restricted Persons in
Texas are properly attributed. 
 Section 5.30. Operation of Oil and Gas Properties. The Oil and Gas Properties (and all
Properties unitized therewith) are being (and, to the extent the same could adversely affect the ownership or operation of the Oil and Gas Properties after the date hereof, have in the past been) maintained, operated and developed in all material
respects in a good and workmanlike manner, in accordance with prudent industry standards and in material conformity with all applicable Laws and in material conformity with all oil, gas or other mineral leases and other contracts and agreements
forming a part of the Oil and Gas Property and in conformity with the Permitted Liens. Each Restricted Person has all governmental licenses and permits necessary or appropriate to own and operate its Oil and Gas Properties, and no Restricted Person
has received notice of any violations in respect of any such licenses or permits. As used in this Section, “Oil and Gas Properties” means Oil and Gas Properties to which Proved Reserves of the Restricted Persons in Texas are properly
attributed.

 Section 6.26. Environmental Matters; Environmental Reviews. 
 (a) Each Restricted Person will
comply in all material respects with all Environmental Laws now or hereafter applicable to such Restricted Person, as well as all contractual obligations and agreements with respect to environmental remediation or other environmental matters, and

 (b) Upon Administrative Agent’s written request, Borrower will promptly furnish to Administrative Agent copies of all written notices of violation,

Each Restricted Person will properly and timely pay all rents, royalties and other payments due and payable under any such leases, contracts, servitudes and other agreements, or under the Permitted Liens, or otherwise attendant to its ownership or
operation of any Oil and Gas Property, unless it is contesting in good faith the validity thereof by appropriate proceedings and for which adequate reserves are maintained in accordance with GAAP. Upon Administrative Agent’s written request,
each Restricted Person will promptly notify Administrative Agent of any claim (or any conclusion by such Restricted Person) that such Restricted Person is obligated to account for any royalties, or overriding royalties or other payments out of
production, on a basis (other than delivery in kind) less favorable to such Restricted Person than proceeds received by Restricted Person (calculated at the well) from sale of production.

conditions under which each Lender is willing to have credit outstanding to Borrower, and to induce each Lender to enter into this Agreement and make the Loans, each of Parent and Borrower warrants, covenants and agrees that until the full and final

on its behalf as Administrative Agent hereunder and under the other Loan Documents and authorizes Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to Administrative Agent by the terms hereof or
thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of Administrative Agent and the Lenders, and neither Borrower nor any other Restricted Person shall have
rights as a third party beneficiary of any of such provisions. Such appointment of Wayzata Investment Partners LLC as Administrative Agent shall not, however, impair or modify any rights, obligations or duties that Wayzata Investment Partners LLC or
any Affiliate of Wayzata Investment Partners LLC otherwise has with respect to any Lender. 
 Section 9.2. Exculpatory
Provisions. Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, Administrative Agent: 
 (a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing; 
 (b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly
contemplated hereby or by the other Loan Documents that Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of Lenders as shall be expressly provided for herein or in the
other Loan Documents), provided that Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose Administrative Agent to liability or that is contrary to any Loan Document or
applicable law; and 
 (c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as Administrative Agent or any of its Affiliates in any capacity. 
 Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of Required Lenders (or such
other number or percentage of the Lenders as shall be necessary, or as Administrative Agent shall believe in good faith shall be 

  

					
		  	52	  	CREDIT AGREEMENT

 
necessary, under the circumstances as provided in Sections 10.1 and 8.2) or (ii) in the absence of its own gross negligence or willful misconduct.
Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to Administrative Agent by Borrower or a Lender. 
 Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made
in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document
or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to Administrative Agent. 

Section 9.3. Reliance by Administrative Agent. Administrative Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been
signed, sent or otherwise authenticated by the proper Person. Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for
relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, Administrative Agent may presume that such condition is satisfactory to such Lender
unless Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. Administrative Agent may consult with legal counsel (who may be counsel for Borrower), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
 Section 9.4. Non-Reliance on Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon Administrative Agent or any other Lender or any of their
Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon
Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. 
 Section 9.5.
Rights as a Lender. The Person serving as Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not Administrative Agent and the term
“Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates
may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Borrower or any Subsidiary or other Affiliate thereof as if such Person were not
Administrative Agent hereunder and without any duty to account therefor to the Lenders. 
  

					
		  	53	  	CREDIT AGREEMENT

 Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it
shall, whether through the exercise of rights under Security Documents or rights of banker’s lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it, taking into account
all distributions made by Administrative Agent under Section 3.1, and such payment causes such Lender Party to have received more than it would have received had such payment been received by Administrative Agent and distributed pursuant to
Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1,
and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Administrative Agent and all Lender Parties share all payments of Obligations as provided in Section 3.1; provided, however, that nothing
herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker’s lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly
consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any
and all rights of banker’s lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this section is
thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required
pursuant to the order of a Tribunal order to be paid on account of the possession of such funds prior to such recovery. 
 Section 9.7.
Investments. Whenever Administrative Agent in good faith determines that it is uncertain about how to distribute to Lender Parties any funds which it has received, or whenever Administrative Agent in good faith determines that there is any
dispute among Lender Parties about how such funds should be distributed, Administrative Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith believes that the
uncertainty or dispute will not be promptly resolved, or if Administrative Agent is otherwise required to invest funds pending distribution to Lender Parties, Administrative Agent shall invest such funds pending distribution; all interest on any
such Investment shall be distributed upon the distribution of such Investment and in the same proportion and to the same Persons as such Investment. All moneys received by Administrative Agent for distribution to Lender Parties (other than to the
Person who is Administrative Agent in its separate capacity as a Lender Party) shall be held by Administrative Agent pending such distribution solely as Administrative Agent for such Lender Parties, and Administrative Agent shall have no equitable
title to any portion thereof. 
 Section 9.8. Resignation of Administrative Agent. Administrative Agent may at any time give
notice of its resignation to the Lenders and Borrower. Upon receipt of any such notice of resignation, Required Lenders shall have the right, in consultation with Borrower, to appoint a successor, which shall be a bank with an office in the United
States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by 
  

					
		  	54	  	CREDIT AGREEMENT

 
Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the
retiring Administrative Agent may on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above provided that if Administrative Agent shall notify Borrower and the Lenders that no qualifying Person has
accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan
Documents (except that in the case of any Collateral held by Administrative Agent on behalf of the Lenders under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such Collateral until such time as a successor
Administrative Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through Administrative Agent shall instead be made by or to each Lender directly, until such time as Required Lenders
appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights,
powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged
therefrom as provided above in this Section). The fees payable by Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between Borrower and such successor. After the retiring
Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.4 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent. 
 Section 9.9. Delegation of Duties. Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or
under any other Loan Document by or through any one or more sub-agents appointed by Administrative Agent. Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their
respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 
 Section 9.10.
Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Restricted
Person, Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether Administrative Agent shall have made any demand on Borrower)
shall be entitled and empowered, by intervention in such proceeding or otherwise 
 (a) to file and prove a claim for the whole amount of the
principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of Lenders and Administrative Agent
(including any claim for the reasonable compensation, expenses, 

  

					
		  	55	  	CREDIT AGREEMENT

 
disbursements and advances of Lenders and Administrative Agent and their respective agents and counsel and all other amounts due Lenders and Administrative
Agent under Section 2.5 and 10.4) allowed in such judicial proceeding; and 
 (b) to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to Administrative Agent and, in the event that Administrative Agent shall consent to the making of such payments directly to Lenders, to pay
to Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of Administrative Agent and its agents and counsel, and any other amounts due Administrative Agent under Sections 2.5 and 10.4. Nothing
contained herein shall be deemed to authorize Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of
any Lender or to authorize Administrative Agent to vote in respect of the claim of any Lender in any such proceeding. 
 Section 9.11.
Guaranty Matters. Each Lender hereby irrevocably authorizes Administrative Agent, at its option and in its discretion, to release any Guarantor from its obligations under the Guaranty (i) if such Person ceases to be a Subsidiary as a
result of a transaction permitted hereunder and (ii) upon termination of each Lender’s Commitment and payment in full of all Obligations (other than contingent indemnification obligations). Upon request by Administrative Agent at any time,
each Lender will confirm in writing Administrative Agent’s authority to release any Guarantor from its obligations under the Subsidiary Guaranty pursuant to this Section 9.11. 
 Section 9.12. Collateral Matters. 
 (a) Each Lender hereby irrevocably authorizes and directs Administrative Agent to (i) enter into the Security Documents for the benefit of such Lender, (ii) instruct Collateral Agent to enter into such Security Documents, and
(iii) provide such other instructions to Collateral Agent that are consistent with Administrative Agent’s authority under this Section 9.12. Each Lender hereby agrees, and each holder of any Note by the acceptance thereof will be
deemed to agree, that, except as otherwise set forth in Section 10.1, any action taken by the Required Lenders, in accordance with the provisions of this Agreement or the Security Documents, and the exercise by the Required Lenders of the
powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of Lenders. Administrative Agent is hereby authorized (but not obligated) on behalf of all of Lenders,
without the necessity of any notice to or further consent from any Lender from time to time prior to, an Event of Default, to take any action with respect to any Collateral or Security Documents which may be necessary to perfect and maintain
perfected the Liens upon the Collateral granted pursuant to the Security Documents. 
 (b) Each Lender hereby irrevocably authorize
Administrative Agent, at its option and in its discretion to release any Lien on any property granted to or held by Administrative Agent under any Loan Document (A) upon termination of each Lender’s Commitment and payment in 

  

					
		  	56	  	CREDIT AGREEMENT

 
full of all Obligations (other than contingent indemnification obligations), (B) that is sold or to be sold as part of or in connection with any sale
permitted hereunder or under any other Loan Document, (C) subject to Section 10.1, if approved, authorized or ratified in writing by the Required Lenders, or (D) in connection with any foreclosure sale or other disposition of
Collateral after the occurrence of an Event of Default. Upon request by Administrative Agent at any time, each Lender will confirm in writing Administrative Agent’s authority to release its interest in particular types or items of Collateral
pursuant to this Section 9.12. 
 (c) Subject to (b) above, Administrative Agent shall (and is hereby irrevocably authorized by
each Lender, to) execute such documents as may be necessary to evidence the release of the Liens granted to Administrative Agent for the benefit of Administrative Agent and Lenders herein or pursuant hereto upon the applicable Collateral; provided
that (i) Administrative Agent shall not be required to execute any such document on terms which, in Administrative Agent’s opinion, would expose Administrative Agent to or create any liability or entail any consequence other than the
release or subordination of such Liens without recourse or warranty and (ii) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or obligations of Borrower or any other Restricted Person in
respect of) all interests retained by Borrower or any other Restricted Person, including the proceeds of the sale, all of which shall continue to constitute part of the Collateral. In the event of any sale or transfer of Collateral, or any
foreclosure with respect to any of the Collateral, Administrative Agent shall be authorized to deduct all expenses reasonably incurred by Administrative Agent from the proceeds of any such sale, transfer or foreclosure. 
 (d) Administrative Agent shall have no obligation whatsoever to any Lender or any other Person to assure that the Collateral exists or is owned by
Borrower or any other Restricted Person or is cared for, protected or insured or that the Liens granted to Administrative Agent herein or in any of the Security Documents or pursuant hereto or thereto have been properly or sufficiently or lawfully
created, perfected, protected or enforced or are entitled to any particular priority, or to exercise or to continue exercising at all or in any manner or under any duty of care, disclosure or fidelity any of the rights, authorities and powers
granted or available to Administrative Agent in this Section 9.12 or in any of the Security Documents, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, Administrative Agent may act
in any manner it may deem appropriate, in its sole discretion, given Administrative Agent’s own interest in the Collateral as one of Lenders and that Administrative Agent shall have no duty or liability whatsoever to Lenders. 
 (e) Each Lender hereby appoints each other Lender as agent for the purpose of perfecting Lenders’ security interest in assets which, in accordance
with Article 9 of the UCC can be perfected only by possession. Should any Lender (other than Administrative Agent) obtain possession of any such Collateral, such Lender shall notify Administrative Agent thereof, and, promptly upon Administrative
Agent’s request therefor shall deliver such Collateral to Administrative Agent or in accordance with Administrative Agent’s instructions.

 (a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender in exercising any right, power or remedy which such Lender Party may have under any of the Loan

power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be
effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or

Documents, (6) release Borrower from its obligation to pay such Lender’s Obligations or any Guarantor from its guaranty of such payment (except as provided by Section 9.11), (7) release all or substantially all of the Collateral

 (b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to
which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Administrative Agent or
any Lender, whether written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or
agreements by any Lender Party as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender Party has any fiduciary obligation toward Borrower with

solely that of debtor and creditor, respectively, provided that, solely for purposes of Section 10.5(c) Administrative Agent shall act 

  

					
		  	58	  	CREDIT AGREEMENT

 
as agent of Borrower in maintaining the Register as set forth therein, (vi) no partnership or joint venture exists with respect to the Loan Documents
between any Restricted Person and any Lender Party, (vii) Administrative Agent is not Borrower’s Administrative Agent, but Administrative Agent for Lenders, provided that, solely for purposes of Section 10.5(c) Administrative Agent
shall act as agent of Borrower in maintaining the Register as set forth therein, (viii) should an Event of Default or Default occur or exist, each Lender Party will determine in its sole discretion and for its own reasons what remedies and
actions it will or will not exercise or take at that time, (ix) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by any Lender Party, or any representative thereof, and no such representation or
covenant has been made, that any Lender Party will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such
Event of Default or Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the truthfulness of the acknowledgments in this section in deciding to execute and deliver this Agreement and to become
obligated hereunder. 
 (c) Joint Acknowledgment. THIS WRITTEN AGREEMENT
AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. 
 THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 
 Section 10.2. Survival of Agreements; Cumulative Nature. All of Restricted Persons’ various representations, warranties, covenants and
agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans and the delivery of the Notes and the
other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender Party and all of Lender Parties’ obligations to Borrower are terminated. Notwithstanding the foregoing or anything herein to the
contrary, any waivers or admissions made by any Restricted Person in any Loan Document, any Obligations under Sections 3.2 through Section 3.6, and any obligations which any Person may have to indemnify or compensate any Lender Party shall
survive any termination of this Agreement or any other Loan Document. All statements and agreements contained in any certificate or other instrument delivered by any Restricted Person to any Lender Party under any Loan Document shall be deemed
representations and warranties by Borrower or agreements and covenants of Borrower under this Agreement. The representations, warranties, indemnities, and covenants made by Restricted Persons in the Loan Documents, and the rights, powers, and
privileges granted to Lender Parties in the Loan Documents, are cumulative, and, except for expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit
to any Lender Party of any such representation, warranty, indemnity, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein
contained shall apply to any similar representation, warranty, indemnity, or covenant contained in any other Loan Document, and each such similar representation, warranty, indemnity, or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various Loan Documents.

Section 10.4(a), Section 6.20, or Section 6.21 to be paid by it to Administrative Agent (or any sub-agent thereof) or any Related Party of any of the foregoing, each Lender severally agrees to pay to Administrative Agent (or any such
sub-agent) or such Related Party, as the case may be, such Lender’s Percentage Share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed
expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against Administrative Agent (or any such sub-agent) in its capacity as such, or against any Related Party of any of the
foregoing acting for Administrative Agent (or any such sub-agent) in connection with such capacity. The obligations of the Lenders under this paragraph (c) are subject to the provisions of Section 2.7.

information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby. 
 (d) Payments. All amounts due under this Section shall be payable not later than ten (10) days after written demand therefor. 
 Section 10.5. Successors and Assigns; Joint and Several Liability. 
 (a) Successors and Assigns Generally. 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 neither Borrower nor any other Restricted Person may assign or otherwise
transfer any of its rights or obligations under any Loan Document without the prior written consent of Administrative Agent and 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, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section or (iii) by way of pledge or assignment of
a security interest subject to the restrictions of subsection (f) of this Section (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 and, to the extent expressly contemplated hereby, the
Related Parties of each of Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
 (b) Assignments by Lenders. With the consent of Administrative Agent and, except when a Default or an Event of Default shall have occurred and is continuing, Borrower (which consent shall not be unreasonably
withheld or delayed in either case), 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 and the other Loan Documents (including all or a portion of its Commitment
and the Loans at the time owing to it); provided that 
 (i) except in the case of an assignment of the entire remaining
amount of the assigning Lender’s Commitment and the Loans 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 Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date
the Assignment and Assumption with respect to such assignment is delivered to Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $1,000,000, unless
Administrative Agent otherwise consents; 
 (ii) 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 Loan or the Commitment assigned,; 
  

					
		  	62	  	CREDIT AGREEMENT

 (iii) any assignment of a Commitment must be approved by Administrative Agent unless the
Person that is the proposed assignee is itself a Lender with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and 
 (iv) the parties to each assignment shall execute and deliver to Administrative Agent an Assignment and Assumption, and the Eligible
Assignee, if it shall not be a Lender, shall deliver to Administrative Agent an Administrative Questionnaire in form satisfactory to Administrative Agent. 
 Subject to acceptance and recording thereof by Administrative Agent pursuant to subsection (c) of this Section, 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, and subject to the requirements of, of Sections 3.2, 3.3, 3.4, and 10.4 with respect to facts and circumstances occurring prior to the effective date of such
assignment. 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. 
 (c) Participations. Any Lender may at any time, without the
consent of, or notice to, Borrower or Administrative Agent, 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 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, and (iii) Borrower, Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement
and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification
or waiver described in the fifth sentence of Section 10.1(a) that affects such Participant. Subject to subsection (e) of this Section, Borrower agrees that each Participant shall be entitled to the benefits of, and subject to the
requirements of, Sections 3.2, 3.3 and 3.4 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by Law, each Participant also shall be entitled
to the benefits of Section 2.10 as though it were a Lender, provided such Participant agrees to be subject to Section 9.6 as though it were a Lender. 
  

					
		  	63	  	CREDIT AGREEMENT

 (d) Limitations upon Participant Rights. A Participant shall not be entitled to receive any
greater payment under Sections 3.2 and 3.4 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with
Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.3 unless Borrower is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of Borrower, to comply with Section 3.3(e) as though it were a Lender. 
 (e) Certain
Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including 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. 
 (f) Joint and Several Liability. All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations
and liabilities. 
 Section 10.6. Confidentiality. Each Lender Party agrees to maintain the confidentiality of the Information
(as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, members, directors, officers, employees, agents, fund participants, rating agencies, advisors (including
attorneys, accountants, consultants, and investment bankers) and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such
Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the
extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or
proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the consent of Borrower or Parent, or (h) to the extent such Information (x) becomes publicly available
other than as a result of a breach of this Section or (y) becomes available to Administrative Agent, any Lender, or any of their respective Affiliates on a nonconfidential basis from a source other than a Restricted Person. 
 For purposes of this Section, “Information” means all information received from Parent or any of its Subsidiaries relating to Parent or any of
its Subsidiaries or any of their respective businesses, other than any such information that is available to any Lender Party on a nonconfidential basis prior to disclosure by Parent or any of its Subsidiaries, provided that, in the case of
information received from Parent or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

parties to the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan

Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in

payable to Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.1, this Agreement shall become effective when it shall have been executed by Administrative Agent and when Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of
each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by email transmission of a PDF copy thereof or telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

PERMITTED BY APPLICABLE LAW, (A) ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY
