for Banks hereunder or any successor thereto.
          “Affiliate” means, as to any Person, any

Agent, Sole Lead Arranger or Book Runner, and “Agents” means Administrative Agent, Syndication Agents, Documentation Agents, Sole Lead Arranger and Book Runner, collectively.

         “Agreement” means this Third Amended and Restated Credit Agreement, including the Schedules and Exhibits
hereto, as the same may be amended or supplemented from time to time.

safety and environmental laws and regulations, and further including without limitation, (a) the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act of

  meanings specified in CERCLA, and the terms “solid waste” and “disposal” (or “disposed”) have the meanings specified in RCRA; provided, however, in the event either CERCLA or RCRA is amended so as to broaden the meaning of any term defined thereby, such broader meaning shall apply subsequent to the effective date of such amendment with respect to all
provisions of this Agreement; and provided further that, to the extent the laws of the state in
which any real or personal property owned, operated or leased by any Company is located establish a meaning for “hazardous substance,” “petroleum,” “release,” “solid waste” or “disposal” which is
broader than that specified in either CERCLA or RCRA, such broader meaning shall apply in so far as such broader meaning is applicable to the real or personal property owned, operated or leased by such Company and located in such state.

         “Applicable Margin” means, for purposes of determining the interest rate applicable to the Loan at any
time, the amount set forth in the table below under the applicable Type of Tranche and opposite the applicable Ratio of Consolidated Funded Debt to Adjusted Consolidated EBITDA. The Applicable Margin in effect at any time shall be based on the Ratio

Section 3.1(c), Section 7.1 and Section 7.2 and the other terms and conditions set forth in
this Agreement, to lend to Borrower from time to time during the Credit Period amounts not to exceed in the aggregate at any one time outstanding, the amount of such Bank’s Commitment reduced by an amount equal to such Bank’s Letter of
Credit Exposure. Each Borrowing shall (i) be in an aggregate principal amount of $500,000 or any larger integral multiple of $500,000 (except that any Adjusted Base Rate Borrowing may be in an amount equal to the Availability (prior to giving
effect to any such Adjusted Base Rate Borrowing) at such time), and (ii) be made from each Bank ratably in accordance with its respective Commitment Percentage. Subject to the foregoing limitations and the other provisions of this Agreement,
Borrower may borrow under this Section 3.1(a), repay amounts borrowed under this Section 3.1(a) and request new Borrowings under this
Section 3.1(a). The Total Commitment as of the Closing Date is the Initial Total Commitment and Administrative Agent has notified Borrower of the Required Reserve Value for such Initial Total
Commitment.
                   (b)         Administrative
Agent, or such Bank designated by Administrative Agent which (without obligation to do so) consents to the same (“Letter of Credit Issuer”), will issue Letters of Credit, from time to
time prior to the date which is five (5) Domestic Business Days prior to the Termination Date, upon request by Borrower, for the account of Borrower or any Restricted Subsidiary designated by Borrower, so long as (i) the sum of (A) the
total Letter of Credit Exposure then existing, and (B) the amount of the requested Letter of Credit does not exceed $10,000,000, and (ii) Borrower would be entitled to a Borrowing under Section 3.1(a) and Section 3.1(c) in the amount of the requested Letter of Credit. Not less than three (3) Domestic Business Days prior to the requested date of
issuance of any such Letter of Credit, Borrower (and any Restricted Subsidiary of Borrower for whose account such Letter of Credit is being issued) shall execute and deliver to Letter of Credit Issuer, Letter of Credit Issuer’s customary letter
of credit application. Each Letter of Credit shall be in form and substance acceptable to Letter of Credit Issuer. No Letter of Credit shall have an expiration date later than the earlier of (i) the Termination Date, or (ii) one (1) year
from the date of issuance. Upon the date of issuance of a Letter of Credit, Letter of Credit Issuer shall be deemed to have sold to each other Bank, and each other Bank shall be deemed to have unconditionally and irrevocably purchased from Letter of
Credit Issuer, a non-recourse participation in the related Letter of Credit and Letter of Credit Exposure equal to such Bank’s Commitment Percentage of such Letter of Credit and Letter of Credit Exposure. Upon request of any Bank, but not less

expiration date of each such Letter of Credit, each Bank’s participation percentage of each such Letter of Credit and the actual dollar amount of each Bank’s participation held by Letter of Credit Issuer(s) thereof for such Bank’s

Exposure to reimburse Letter of Credit Issuer for the payment under the Letter of Credit, whether or not Borrower would then be entitled to a Borrowing pursuant to the terms hereof, and each Bank which participated in such Letter of Credit and
Letter of Credit Exposure shall be obligated to lend its Commitment Percentage of such Adjusted Base Rate Borrowing. At the time of issuance of each Letter of Credit, Borrower shall pay to Administrative Agent in respect of such Letter of Credit
(a) the applicable Letter of Credit Fee, and (b) the applicable Letter of Credit Fronting Fee. Administrative Agent shall distribute the Letter of Credit Fee payable upon the issuance of each Letter of Credit to Banks in accordance with
their respective Commitment Percentages, and Administrative Agent shall distribute the Letter of Credit Fronting Fee to the Letter of Credit Issuer which issued such Letter of Credit for its own account. Any (y) material amendment or
modification, or (z) renewal or extension of any Letter of Credit shall be deemed to be the issuance of a new Letter of Credit for purposes of this Section 3.1(b). Notwithstanding anything to
the contrary contained herein, Borrower shall pay to Administrative Agent in connection with the issuance of each Letter of Credit and/or any amendment or modification of any nature to any existing Letter of Credit, Administrative Agent’s usual
and customary fees for the issuance of, amendments or modifications to, and processing of, Letters of Credit.
          Upon the occurrence of an Event of Default, and
also on the date which is five (5) Domestic Business Days prior to the Termination Date, Borrower shall, on the next succeeding Domestic Business Day, deposit with Administrative Agent such funds as Administrative Agent may request, up to a
maximum amount equal to the aggregate existing Letter of Credit Exposure of all Banks. Any funds so deposited shall be held by Administrative Agent for the ratable benefit of all Banks as security for the outstanding Letter of Credit Exposure and
the other Obligations, and Borrower will, in connection therewith, execute and deliver such security agreements in form and substance satisfactory to Administrative Agent which it may, in its discretion, require. As drafts or demands for payment are
presented under any Letter of Credit, Administrative Agent shall apply such funds to satisfy such drafts or demands. When all Letters of Credit have expired and the Obligations have been repaid in full (and the Commitments of all Banks have
terminated) or such Event of Default has been cured to the satisfaction of Required Banks, Administrative Agent shall release to Borrower any remaining funds deposited under this Section 3.1(b).
Whenever Borrower is required to make deposits under this Section 3.1(b) and fails to do so on the day such deposit is due, Administrative Agent or any Bank may, without notice to Borrower, make
such deposit (whether by application of proceeds of any collateral for the Obligations, by transfers from other accounts maintained with any Bank or otherwise) using any funds then available to any Bank of Borrower, and of its Restricted
Subsidiaries, any guarantor, or any other Person liable for all or any part of the Obligations.
          Notwithstanding anything to the contrary contained herein,
Borrower hereby unconditionally agrees to reimburse each Letter of Credit Issuer immediately upon demand by such Letter of Credit Issuer, and in immediately available funds, for any payment or
 24

 
  disbursement made by such Letter of Credit Issuer under any Letter of Credit issued by it. Payment shall be made by Borrower with interest on the amount so paid or
disbursed by Letter of Credit Issuer from and including the date payment is made under any Letter of Credit to and including the date of payment, at the lesser of (i) the Maximum Lawful Rate, or (ii) the Default Rate. The obligations of
Borrower under this paragraph will continue until all Letters of Credit have expired and all reimbursement obligations with respect thereto have been paid in full by Borrower, and until all other Obligations shall have been paid in full.

                  (c)         No Bank will be obligated to lend to
Borrower under this Section 3.1 or incur Letter of Credit Exposure, and Borrower shall not be entitled to borrow hereunder or obtain Letters of Credit hereunder (i) during the existence of any
Borrowing Base Deficiency, or (ii) in an amount which would cause a Borrowing Base Deficiency. Nothing in this Section 3.1(c) shall be deemed to limit any Bank’s obligation to fund its
ratable share of Adjusted Base Rate Borrowings with respect to its participation in Letters of Credit made as a result of any drawing under any Letter of Credit.
          SECTION 3.2         Method of Borrowing.
                   (a)         In order to request any Borrowing
hereunder, Borrower shall hand deliver, telex or telecopy to Administrative Agent a duly completed Request for Borrowing (herein so called) prior to 12:00 noon (Chicago, Illinois time), (i) at least one (1) Domestic Business Day before the
Borrowing Date specified for a proposed Adjusted Base Rate Borrowing, and (ii) at least three (3) Eurodollar Business Days before the Borrowing Date of a proposed Eurodollar Borrowing. Each such Request for Borrowing shall be substantially in
the form of Exhibit D hereto, and shall specify:

	 	            (i)      whether such Borrowing is to be an Adjusted Base Rate Borrowing or a Eurodollar
Borrowing;

	 	            (ii)    the Borrowing Date of such Borrowing, which shall be a Domestic Business Day in the case of an Adjusted Base
Rate Borrowing, or a Eurodollar Business Day in the case of a Eurodollar Borrowing; 

	 	            (iii)   the aggregate amount of such Borrowing; and

	 	            (iv)    in the case of a Eurodollar Borrowing, the duration of the Interest Period applicable thereto, subject to the
provisions of the definition of Interest Period.

                   (b)         Upon receipt of a Request for Borrowing described in Section 3.2(a) above, Administrative Agent shall promptly
notify each Bank of the contents thereof and the amount of the Borrowing to be loaned by such Bank pursuant thereto, and such Request for Borrowing shall not thereafter be revocable by Borrower.
                   (c)         Not later than 12:00 noon (Chicago,
Illinois time) on the date of each Borrowing, each Bank shall make available its Commitment Percentage of such Borrowing, in Federal or other funds immediately available in Chicago, Illinois to Administrative Agent at its address set forth on
Schedule 2.1 hereto. Notwithstanding the foregoing, if Borrower delivers to Administrative Agent a Request for Borrowing prior to 10:00 a.m. (Chicago, Illinois time) on a
 25

 
  Domestic Business Day requesting an Adjusted Base Rate Borrowing on such day, each Bank shall use its best efforts to make available to Administrative Agent its
Commitment Percentage of such Borrowing by 1:00 p.m. (Chicago, Illinois time) on the same day. Unless Administrative Agent determines that any applicable condition specified in Section 7.2 has not
been satisfied, Administrative Agent will make the funds so received from Banks available to Borrower at Administrative Agent’s aforesaid address.
          SECTION 3.3         Method of Requesting Letters of Credit.
                   (a)         In order to request any Letter of Credit
hereunder, Borrower shall hand deliver, telex or telecopy to Administrative Agent a duly completed Request for Letter of Credit (herein so called) prior to 12:00 noon (Chicago, Illinois time) at least three (3) Domestic Business Days before the date
specified for issuance of such Letter of Credit. Each Request for Letter of Credit shall be substantially in the form of Exhibit E hereto, shall be accompanied by the applicable Letter of Credit
Issuer’s duly completed and executed letter of credit application and agreement and shall specify:

	 	            (i)      the requested date for issuance of such Letter of Credit;

	 	            (ii)    the terms of such requested Letter of Credit, including the name and address of the beneficiary, the stated
amount, the expiration date and the conditions under which drafts under such Letter of Credit are to be available; and

	 	            (iii)   the purpose of such Letter of Credit.

                   (b)         Upon receipt of a Request for Letter of
Credit described in Section 3.3(a) above, Administrative Agent shall promptly notify each Bank and the proposed Letter of Credit Issuer of the contents thereof, including the amount of the
requested Letter of Credit, and such Request for Letter of Credit shall not thereafter be revocable by Borrower.
                   (c)         No later than 12:00 noon (Chicago,
Illinois time) on the date each Letter of Credit is requested, unless Administrative Agent or the applicable Letter of Credit Issuer determines that any applicable condition precedent set forth in Section 7.2 hereof has not been satisfied, the applicable Letter of Credit Issuer will issue and deliver such Letter of Credit pursuant to the instructions of Borrower.
          SECTION 3.4         Notes. Each
Bank’s Commitment Percentage of the Loan shall be evidenced by a single Note payable to the order of such Bank in an amount equal to such Bank’s Commitment Percentage of the Maximum Total Commitment Amount.
          SECTION 3.5         Interest Rates; Payments.
                   (a)         The principal
amount of the Loan outstanding from day to day which is the subject of an Adjusted Base Rate Tranche shall bear interest at a rate per annum equal to the sum of the Applicable Margin plus the Adjusted Base Rate in effect from day to day;
providedthat, in no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on any portion of the principal of
the Loan subject to an Adjusted Base Rate Tranche shall be payable as it accrues on each Quarterly Date and on the Termination Date.
 26

 
                    
(b)         The principal amount of the Loan outstanding from day to day which is the subject of a Eurodollar Tranche shall bear interest for the Interest Period applicable thereto at
a rate per annum equal to the sum of the Applicable Margin plus the applicable Adjusted Eurodollar Rate; provided, that, in no event shall the rate charged
hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on any portion of the principal of the Loan subject to a Eurodollar Tranche having an Interest Period of one (1), two (2) or three (3) months shall be payable on the last day of
the Interest Period applicable thereto. Interest on any portion of the principal of the Loan subject to a Eurodollar Tranche having an Interest Period of six (6) months shall be payable on the last day of the Interest Period applicable thereto and
on each Quarterly Date during such Interest Period.
                   (c)         So long as no Default or Event of Default shall be continuing, subject to the provisions of this Section 3.5,
Borrower shall have the option of having all or any portion of the principal outstanding under the Loan borrowed by it be the subject of an Adjusted Base Rate Tranche or one (1) or more Eurodollar Tranches, which shall bear interest at rates based
upon the Adjusted Base Rate and the Adjusted Eurodollar Rate, respectively (each such option is referred to herein as an “Interest Option”); provided, that, each Eurodollar Tranche shall be in a minimum amount of $500,000 and shall be in an amount which is an integral multiple of $500,000. Each change in an
Interest Option made pursuant to this Section 3.5(c) shall be deemed both a payment in full of the portion of the principal of the Loan which was the subject of the Adjusted Base Rate Tranche or
Eurodollar Tranche from which such change was made and a Borrowing (notwithstanding that the unpaid principal amount of the Loan is not changed thereby) of the portion of the principal of the Loan which is the subject of the Adjusted Base Rate
Tranche or Eurodollar Tranche into which such change was made. Prior to the termination of each Interest Period with respect to each Eurodollar Tranche, Borrower shall give written notice (a “Rollover
Notice”) in the form of Exhibit F attached hereto to Administrative Agent of the Interest Option which shall be applicable to such portion of the principal of the
Loan upon the expiration of such Interest Period. Such Rollover Notice shall be given to Administrative Agent at least one (1) Domestic Business Day, in the case of an Adjusted Base Rate Tranche selection, and three (3) Eurodollar Business Days, in
the case of a Eurodollar Tranche selection, prior to the termination of the Interest Period then expiring. If Borrower shall specify a Eurodollar Tranche, such Rollover Notice shall also specify the length of the succeeding Interest Period (subject
to the provisions of the definitions of such term), selected by Borrower. Each Rollover Notice shall be irrevocable and effective upon notification thereof to Administrative Agent. If the required Rollover Notice shall not have been timely received
by Administrative Agent, Borrower shall be deemed to have elected that the principal of the Loan subject to the Interest Period then expiring be the subject of an Adjusted Base Rate Tranche upon the expiration of such Interest Period and Borrower
will be deemed to have given Administrative Agent notice of such election. Subject to the limitations set forth in this Section 3.5(c) on the minimum amount of Eurodollar Tranches, Borrower shall
have the right to convert each Adjusted Base Rate Tranche to a Eurodollar Tranche by giving Administrative Agent a Rollover Notice of such election at least three (3) Eurodollar Business Days prior to the date on which Borrower elects to make such
conversion (a “Conversion Date”). The Conversion Date selected by Borrower shall be a Eurodollar Business Day. Notwithstanding anything in this Section 3.5 to the contrary, no portion of the principal of the Loan which is the subject of an Adjusted Base Rate Tranche may be converted to a Eurodollar Tranche and no Eurodollar Tranche may be continued as
such when any Default or Event of Default has occurred and is continuing, but each
 27

 
  such Tranche shall be automatically converted to an Adjusted Base Rate Tranche on the last day of each applicable Interest Period. In no event shall more than four
(4) Interest Options be in effect with respect to the Loan at any time.
                   (d)         Notwithstanding anything to the contrary set forth in Section 3.5(a) or Section 3.5(b) above, all overdue principal of and, to the extent permitted by law, overdue interest on the Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the
lesser of (a) the Default Rate, and (b) the Maximum Lawful Rate.
                   (e)         Administrative Agent shall determine each interest rate applicable to the Loan in accordance with the terms hereof. Administrative Agent shall promptly notify
Borrower and Banks by telex, telecopy or cable of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error.
                   (f)         Notwithstanding the foregoing, if at any
time the rate of interest calculated with reference to the Adjusted Base Rate or the Eurodollar Rate hereunder (the “contract rate”) is limited to the Maximum Lawful Rate, any
subsequent reductions in the contract rate shall not reduce the rate of interest on the Loan below the Maximum Lawful Rate until the total amount of interest accrued equals the amount of interest which would have accrued if the contract rate had at
all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of any Note, the total amount of interest paid or accrued on such Note is less than the amount of interest which would have accrued if the
contract rate had at all times been in effect with respect thereto, then at such time, to the extent permitted by law, Borrower shall pay to the holder of such Note an amount equal to the difference between (i) the lesser of the amount of
interest which would have accrued if the contract rate had at all times been in effect and the amount of interest which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (ii) the amount of interest actually paid
on such Note.
                   (g)         Interest
payable on the principal of any portion of the Loan subject to a Eurodollar Tranche shall be computed based on the number of actual days elapsed assuming that each calendar year consisted of 360 days. Interest payable on the principal of any portion
of the Loan subject to an Adjusted Base Rate Tranche shall be computed based on the number of actual days elapsed and based on the actual number of days in the calendar year for which accrued interest is being computed.
                   (h)         Borrower hereby unconditionally promises
to pay to Administrative Agent for the account of each Bank, the then unpaid principal amount of the Loan owing to each Bank on the Termination Date (or on such earlier date on which the Loan becomes due and payable pursuant to Article XII). Borrower hereby further unconditionally agrees to pay interest on the unpaid principal amount of the Loan from time to time outstanding from the date hereof until payment in full thereof at the rates
per annum, and on the dates, set forth in this Section 3.5. 
          SECTION 3.6         Mandatory Prepayments. Upon the occurrence of any Borrowing Base Deficiency, Borrower
shall make the mandatory prepayments of the Loan required by Section 5.4 hereof.
 28

 
           SECTION 3.7         Voluntary Prepayments. Borrower may, subject to Section 14.5 and the other provisions of this Agreement, prepay the principal of the
Loan in whole or in part. Any partial prepayment shall be in a minimum amount of $500,000 and shall be in an integral multiple of $500,000.
          SECTION 3.8         Mandatory Termination of Commitments; Termination Date and Maturity. The Commitment of
each Bank shall terminate on the Termination Date (or on such earlier date on which such Commitments are terminated pursuant to Article XII). The outstanding principal balance of the Loan, all
accrued but unpaid interest thereon, all accrued but unpaid fees hereunder and under the other Loan Papers, and all other Obligations shall be due and payable in full on the Termination Date (or on such earlier date on which the Loan becomes due and
payable pursuant to Article XII).
          SECTION 3.9         Voluntary Reduction of Total Commitment. Borrower may, once during each period between
Periodic Determinations, by notice to Administrative Agent not less than three (3) Domestic Business Day prior to the effective date of any such reduction, reduce the Total Commitment (and thereby reduce the Commitment of each Bank ratably in
accordance with such Bank’s Commitment Percentage) in amounts not less than $10,000,000 or any larger multiple of $5,000,000. On the effective date of any such reduction in the Total Commitment, Borrower shall, to the extent required as a
result of such reduction, make a principal payment on the Loan in an amount sufficient to cause the Outstanding Credit to be equal to or less than the Total Commitment as thereby reduced. Notwithstanding the foregoing, Borrower shall not be
permitted to voluntarily reduce the Total Commitment (a) if, as a result of such reduction, Borrower would be required to prepay all or any portion of the principal amount of any Eurodollar Tranche prior to the last day of the Interest Period
applicable thereto, or (b) to an amount less than the aggregate Letter of Credit Exposure of all Banks.
          SECTION 3.10         Voluntary Increase of Total Commitment. So long as no Default or Event of Default has
occurred and is continuing, Borrower shall have the right to increase the Total Commitment by increasing the existing Commitments and/or obtaining additional Commitments (the amount of such increase is herein called the “Increase”), either from (a) one or more of the Banks, or (b) another financial institution provided that (i) Borrower shall have notified Administrative Agent in writing of the amount of the Increase
and Administrative Agent shall have notified Borrower and Banks of the Required Reserve Value for the Total Commitment as increased by the Increase, (ii) each Bank shall have had the option to increase its Commitment up to its pro rata share
(such pro rata share to be computed prior to the addition of any new Bank under the terms of this Section 3.10 and Section 15.10(f) hereof) of the Increase
within ten (10) days following receipt of notice from Administrative Agent pursuant to clause (i) above, (iii) Administrative Agent shall have approved any new Bank, (iv) any such new Bank shall have assumed all of the rights and
obligations of a “Bank” hereunder, (v) the procedure described in Section 15.10(f) shall have been complied with, (vi) first and prior Liens (subject only to Permitted
Encumbrances) shall have been created by Mortgages in favor of Administrative Agent encumbering the Minimum Value of the oil and gas properties owned by Borrower and its Restricted Subsidiaries after giving effect to the Increase and based upon the
new Required Reserve Value as described in clause (i) above, and (vii) after giving effect to the Increase, the Total Commitment shall not exceed the Borrowing Base then in effect.
 29

 
           SECTION 3.11         Application of Payments. Each repayment pursuant to Section 3.6, Section 3.7, Section 3.8, Section 3.9 and Section 5.4 shall be made together with accrued interest to the date of payment, and
shall be applied to payment of the Loan in accordance with Section 4.2 and the other provisions of this Agreement.
          SECTION 3.12         Commitment Fee. On the Termination Date and on each Quarterly Date prior to the Termination Date, commencing on March 31, 2003, Borrower shall pay to Administrative Agent, for the ratable benefit of each Bank, a commitment fee equal to the Commitment
Fee Percentage (computed on the basis of actual days elapsed and as if each calendar year consisted of 360 days) of the average daily Availability for the Fiscal Quarter (or portion thereof) ending on such date.
          SECTION 3.13         Agency and Other Fees. Borrower shall pay to Administrative Agent and its Affiliates such fees and other amounts as Borrower shall be required to pay to Administrative Agent and its Affiliates from time to time pursuant to any separate
agreement between Borrower and Administrative Agent or any of its Affiliates setting forth the compensation to be paid to Administrative Agent and its Affiliates in consideration for acting as Administrative Agent hereunder and for providing other
services in connection with the credit facilities provided pursuant hereto. Such fees and other amounts shall be retained by Administrative Agent and its Affiliates, and no Bank (other than Administrative Agent) shall have any interest
therein.
 ARTICLE IV
GENERAL PROVISIONS
          SECTION 4.1         Delivery and Endorsement of Notes. On or before the Closing Date, Administrative Agent
shall deliver to each Bank the Note payable to such Bank. Each Bank may endorse (and prior to any transfer of its Note shall endorse) on the schedule attached to its Note appropriate notations to evidence the date and amount of each advance of funds
made by it in respect of any Borrowing, the Interest Period applicable thereto, and the date and amount of each payment of principal received by such Bank with respect to the Loan; provided,
that, the failure by any Bank to so endorse its Note shall not affect the liability of Borrower for the repayment of all amounts outstanding under such Notes together with interest thereon. Each Bank is
hereby irrevocably authorized by Borrower to endorse its Note and to attach to and make a part of any Note a continuation of any such schedule as required.
          SECTION 4.2         General Provisions as to Payments.
                   (a)         Borrower shall make each payment of
principal of, and interest on, the Loan and all fees payable by Borrower hereunder not later than 12:00 noon (Chicago, Illinois time) on the date when due, in Federal or other funds immediately available in Chicago, Illinois, to Administrative Agent
at its address set forth on Schedule 2.1 hereto. Administrative Agent will promptly (and if such payment is received by Administrative Agent by 10:00 a.m. (Chicago, Illinois time), and otherwise if
reasonably possible, on the same Domestic Business Day) distribute to each Bank its Commitment Percentage of each such payment received by Administrative Agent for the account of Banks. Whenever any payment of principal of, or interest on, that
portion of the Loan subject to an Adjusted Base Rate Tranche or of fees shall be
 30

 
  due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day (subject to the
definition of Interest Period). Whenever any payment of principal of, or interest on, that portion of the Loan subject to a Eurodollar Tranche shall be due on a day which is not a Eurodollar Business Day, the date for payment thereof shall be
extended to the next succeeding Eurodollar Business Day (subject to the definition of Interest Period). If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.
Borrower hereby authorizes Administrative Agent to charge from time to time against Borrower’s account or accounts with Administrative Agent any amount then due by Borrower.
                   (b)         Prior to the occurrence of an Event of
Default, all principal payments received by Banks with respect to the Loan shall be applied first to Eurodollar Tranches outstanding under the Loan with Interest Periods ending on the date of such payment, then to the Adjusted Base Rate Tranches
outstanding under the Loan, and then to Eurodollar Tranches outstanding under the Loan next maturing until such principal payment is fully applied.
                   (c)         After the occurrence of an Event of
Default, all amounts collected or received by Administrative Agent or any Bank from Borrower and its Restricted Subsidiaries or in respect of any of the assets of Borrower or any of its Restricted Subsidiaries shall be applied first to the payment
of all proper costs incurred by Administrative Agent in connection with the collection thereof (including reasonable expenses and disbursements of counsel to Administrative Agent), second to the payment of all proper costs incurred by Banks in
connection with the collection thereof (including reasonable expenses and disbursements of counsel to Banks), third to the reimbursement of any advances made by Banks to effect performance of any unperformed covenants of Borrower or any of its
Restricted Subsidiaries under any of the Loan Papers, fourth to the payment of any unpaid fees required pursuant to Section 3.13, fifth to the payment of any unpaid fees required pursuant to
Section 3.1(b) and Section 3.12, sixth to each Bank pro rata for application to the Obligations owing to it, and seventh to establish the
deposits required by Section 3.1(b) if any. All payments received by a Bank after the occurrence of an Event of Default for application to the principal of the Loan pursuant to this Section 4.2(c) shall be applied by such Bank in the manner provided in Section 4.2(b).
 ARTICLE V
BORROWING BASE
          SECTION 5.1         Reserve and Related Asset Report; Proposed Borrowing Base. The aggregate amount of
credit available to Borrower under this Agreement shall be limited by a Borrowing Base (herein so called) which shall be determined by Banks at the times and in accordance with the standards and procedures set forth in this Article V. As soon
as available and in any event by March 31 and August 31 of each year commencing March 31, 2003, Borrower shall deliver to each Bank a Reserve Report and Related Asset Report prepared as of the immediately preceding December 31
and June 30, respectively; provided, that Borrower shall not be required to deliver a Related Asset Report unless Borrower intends to request
Administrative Agent and Banks to take the value of Related Assets into account for purposes of establishing the Borrowing Base. On or before each April 10 and October 10 of each year
 31

  
  
   
 commencing April 10, 2003, Borrower shall notify each Bank of the Borrowing Base that Borrower requests for the period commencing on the
next Determination Date.
          SECTION 5.2         Periodic Determination of
Borrowing Base. Based in part on the Reserve Reports and Related Asset Reports delivered pursuant to Section 5.1, Administrative Agent shall,
not later than ten (10) days prior to each Determination Date commencing with the Determination Date falling on May 1, 2003 (or such date promptly thereafter as reasonably possible based on the engineering and other information available to
Banks), submit a proposed Borrowing Base to become effective on such Determination Date to Banks for their approval. In the event Required Banks, or all Banks in the event of a proposed increase in the Borrowing Base, fail to promptly approve such
proposed Borrowing Base, Administrative Agent shall propose one or more alternative Borrowing Bases to Banks and shall consult with Banks regarding the proposed Borrowing Base until such time as Required Banks, or all Banks in the event of a
proposed increase in the Borrowing Base, approve a Borrowing Base proposed by Administrative Agent. Promptly upon the approval by Required Banks, or all Banks in the event of a proposed increase in the Borrowing Base to become effective on a
Determination Date (or such date promptly thereafter as reasonably possible based on the engineering and other information available to Banks), Administrative Agent shall provide written notice to Borrower of the amount of such Borrowing Base and
the Required Reserve Value for the Total Commitment then in effect. In the event Administrative Agent and Required Banks, or all Banks in the event of a proposed increase in the Borrowing Base, fail to approve a Borrowing Base (and notify Borrower
of the amount thereof) on or prior to any applicable Determination Date (or such date promptly thereafter as reasonably possible based on the engineering and other information available to Banks), the Borrowing Base (and the Required Reserve Value)
in effect prior to such Determination Date shall remain in effect thereafter until such time as Administrative Agent and Required Banks, or all Banks in the event of a proposed increase in the Borrowing Base, approve such Borrowing Base (which shall
each become effective immediately upon notice to Borrower from Administrative Agent setting forth the amount thereof). Any determination of a proposed Borrowing Base and/or the Required Reserve Value by Administrative Agent and any decision by Banks
regarding the approval or disapproval of any Borrowing Base shall be made by Administrative Agent and Banks in their sole discretion in accordance with their respective standards for oil and gas loans, which may vary between Administrative Agent and
Banks and from Bank to Bank. Without limiting the right of Administrative Agent to propose the amount of any Borrowing Base (or determine the amount of any Required Reserve Value) or the right of Banks to approve or disapprove such proposed
Borrowing Base in their sole discretion, Borrower acknowledges and agrees that subject to Administrative Agent’s and Banks’ consistent application of their respective standards for similar loans, Administrative Agent and Banks (i) may
make such assumptions regarding appropriate existing and projected pricing for hydrocarbons as they deem appropriate in their sole discretion, (ii) may make such assumptions regarding projected rates and quantities of future production of
hydrocarbons from oil and gas properties and Related Assets owned by Borrower and its Restricted Subsidiaries as they deem appropriate in their sole discretion, (iii) may consider the projected cash requirements of Borrower and its
Subsidiaries, including, without limitation, debt service and lease obligations of Borrower and its Subsidiaries, (iv) will not consider any asset other than oil and gas reserves and Related Assets, (v) will not consider any asset owned by
an entity other than Borrower and its Restricted Subsidiaries, and (vi) may make such other assumptions, considerations and exclusions as each Bank deems appropriate in the exercise of its sole discretion.
 32

           
SECTION 5.3         Special Determination of Borrowing Base. In addition to the redeterminations of the Borrowing Base
pursuant to Section 5.2, Borrower and Required Banks may each request a Special Determination of the Borrowing Base once in each Fiscal Year. In the event Required Banks request such a Special
Determination, Administrative Agent shall promptly deliver notice of such request to Borrower, and Borrower shall, within ten (10) days following the date of such request, deliver to Banks a Related Asset Report and a Reserve Report prepared as of
the last day of the calendar month preceding the date of such request. In the event Borrower requests a Special Determination, Borrower shall deliver written notice of such request to Banks which shall include (i) a Related Asset Report and a
Reserve Report prepared as of a date not more than thirty (30) days prior to the date of such request, and (ii) the amount of the Borrowing Base requested by Borrower and to become effective on the Determination Date applicable to such Special
Determination. Upon receipt of such Reserve Report and Related Asset Report, Administrative Agent shall, subject to approval of Required Banks, or all Banks in the event of a proposed increase in the Borrowing Base, redetermine the Borrowing Base in
accordance with the procedure set forth in Section 5.2 which Borrowing Base shall become effective on the Determination Date applicable to such Special Determination (or as soon thereafter as
Administrative Agent and Required Banks, or all Banks in the event of a proposed increase in the Borrowing Base, approve such Borrowing Base and provide notice thereof to Borrower).
          
SECTION 5.4         Borrowing Base Deficiency. If a Borrowing Base Deficiency exists at any time, Borrower shall,
within ninety (90) days following the date such Borrowing Base Deficiency first occurs, at its option, either (a) make a prepayment of principal on the Loan in an amount sufficient to eliminate such Borrowing Base Deficiency, and if such
Borrowing Base Deficiency cannot be eliminated by prepaying the Loan in full (as a result of outstanding Letter of Credit Exposure), Borrower shall also deposit with Administrative Agent sufficient funds to be held by Administrative Agent as
security for outstanding Letter of Credit Exposure in the manner contemplated by Section 3.1(b) as necessary to eliminate such Borrowing Base Deficiency, (b) submit additional oil and gas properties owned by Borrower and its Restricted
Subsidiaries for consideration in connection with the determination of the Borrowing Base which Administrative Agent and Required Banks deem sufficient in their sole discretion to eliminate such Borrowing Base Deficiency, or (c) take such other
action as Administrative Agent and Required Banks shall deem appropriate in their sole discretion to eliminate such Borrowing Base Deficiency.
          
SECTION 5.5         Initial Borrowing Base. Notwithstanding anything contained herein to the contrary, the Borrowing
Base in effect during the period from the Closing Date until the date of the first Special or Periodic Determination after the Closing Date shall be the Initial Borrowing Base.
 ARTICLE VI
COLLATERAL AND GUARANTEES
          
SECTION 6.1         Collateral.
                   (a)         The Obligations shall be secured by
first and prior Liens (subject only to Permitted Encumbrances) covering and encumbering (i) the Minimum Value of the oil and gas

                   (i)         In the event any notification is
provided by Borrower to any Bank or Administrative Agent pursuant to Section 9.1(h) hereof or Administrative Agent or any Bank otherwise learns of any event or condition under which any such notice

stating that a review of such event, condition or circumstance has been undertaken (the scope of which shall be acceptable to Administrative Agent and Required Banks) and detailing the findings, conclusions, and recommendations of such consultant.
Borrower shall bear all expenses and costs associated with such review and updates thereof, as well as all remediation or curative action recommended by any such environmental consultant; and
                   (j)         from time to time such additional

result of a merger or consolidation expressly permitted pursuant to Section 10.4, and (b) maintain its good standing and qualification to transact business in all jurisdictions where the
failure to maintain good standing or qualification to transact business could have a material adverse effect on the financial condition or operations of Borrower or any of its Restricted Subsidiaries individually or Borrower and its Restricted

to determine the status thereof.
          
SECTION 9.5         Right of Inspection. Borrower will permit, and will cause each of its
Subsidiaries to permit, any officer, employee or Agent of Administrative Agent or any Bank to visit and inspect any of the assets of Borrower and its Subsidiaries, examine Borrower’s and its Subsidiaries’ books of record and accounts, take
copies and extracts therefrom, and discuss the affairs, finances and accounts of Borrower and its Subsidiaries with any of Borrower’s and its Subsidiaries’ officers, accountants and auditors, all at such reasonable times and as often as
Administrative Agent or any Bank may desire, which, after and during the continuance of an Event of Default, shall all be at the expense of Borrower. Banks covenant and agree to preserve the confidentiality of any information with respect to which
Borrower or any of its Subsidiaries have an obligation of confidentiality to a third party (to the extent such obligation has been disclosed to Banks), except to the extent Banks are required to disclose such information pursuant to any applicable
law, rule or regulation of any governmental body or pursuant to the order of any court of competent jurisdiction.
          
SECTION 9.6         Maintenance of Insurance. Borrower will, and will cause each of its

customarily carried by businesses similarly situated including, without limitation, the following: (a) workmen’s compensation insurance; (b) employer’s liability insurance; (c) comprehensive general public liability and
property damage insurance in respect of all activities in which Borrower or any of its Subsidiaries might incur personal liability for the death or injury of an employee or third person, or damage to or destruction of another’s property;

automobile liability insurance. All loss payable clauses or provisions in all policies of insurance maintained by Borrower pursuant to this Section 9.6 shall be endorsed in favor of and made payable to Administrative Agent for the ratable
benefit of Banks, as their interests may appear. Administrative Agent for the ratable benefit of Banks shall have the right to collect, and Borrower hereby assigns to Administrative Agent for the ratable benefit of Banks, any and all monies that may
become payable under any such policies of insurance by reason of damage, loss or destruction of any property which stands as security for the Obligations or any part thereof, and Administrative Agent may, at its election, either apply for the
ratable benefit of Banks all or any part of the sums so collected toward payment of the Obligations (or the portion thereof with respect to which such property stands as security), whether or not such Obligations are then due and payable, in such
manner as Administrative Agent may elect or release same to Borrower.
          
SECTION 9.7         Payment of Taxes and Claims. Borrower will, and will cause each of its

without limitation, claims for labor,
 46

 
 services, materials and supplies) for sums which have become due and payable and which by law have or might become a Lien (other than a Permitted Encumbrance) on any of its assets;
provided, however, no payment of Taxes or claims shall be required if (i) the amount, applicability or validity thereof is currently being contested in good faith by appropriate action promptly initiated and diligently conducted in accordance
with good business practices and no material part of the property or assets of Borrower or any of its Subsidiaries are subject to levy or execution, (ii) Borrower, as and to the extent required in accordance with generally accepted accounting
principles, shall have set aside on its books, reserves (segregated to the extent required by generally accepted accounting practices) deemed by it to be adequate with respect thereto, and (iii) Borrower has notified Administrative Agent of
such circumstances, in detail satisfactory to Administrative Agent.

to, comply with all laws, their respective articles and certificates of incorporation, bylaws, partnership agreements, regulations and similar organizational documents and all Material Agreements to which Borrower or any Subsidiary of Borrower is a
party, if a violation, alone or when combined with all other such violations, could have a material adverse effect on the financial condition or operations of Borrower or any of its Restricted Subsidiaries individually or Borrower and its Restricted
Subsidiaries taken as a whole.
          
SECTION 9.9         Operation of Properties and Equipment.

its Subsidiaries to, maintain, develop and operate their respective oil and gas properties and Related Assets in a good and workmanlike manner, and observe and comply with all of the terms and provisions, express or implied, of all oil and gas
leases relating to such properties so long as such oil and gas leases are capable of producing hydrocarbons and accompanying elements in paying quantities, to the extent that the failure to so observe and comply could have a material adverse effect
on the financial condition or operations of Borrower individually or Borrower and its Subsidiaries taken as a whole.
                   (b)         Borrower will, and will cause each of
its Subsidiaries to, comply in all respects with all contracts and agreements applicable to or relating to their respective oil and gas properties or the production and sale of hydrocarbons and accompanying elements therefrom, except to the extent a
failure to so comply could not have a material adverse effect on the financial condition or operations of Borrower individually or Borrower and its Subsidiaries taken as a whole.
                   (c)         Borrower will, and will cause each of
its Subsidiaries at all times to, maintain, preserve and keep all operating equipment used with respect to the oil and gas properties of Borrower in proper repair, working order and condition, and make all necessary or appropriate repairs, renewals,
replacements, additions and improvements thereto so that the efficiency of such operating equipment shall at all times be properly preserved and maintained, provided that no item of operating equipment need be so repaired, renewed, replaced, added
to or improved, if Borrower shall in good faith determine that such action is not necessary or desirable for the continued efficient and profitable operation of the business of Borrower and its Subsidiaries.
 47

 
                    (d)         With respect to the oil and gas properties of Borrower and its Subsidiaries which are operated by operators other than Borrower or one of its Subsidiaries, Borrower and its Subsidiaries shall not be obligated to directly perform any
undertakings contemplated by the covenants and agreements contained in this Section 9.9 which are performable only by such operators and are beyond the control of Borrower, but shall be obligated
to seek to enforce such operators’ contractual obligations to maintain, develop and operate the oil and gas properties subject to such operating agreements.
          
SECTION 9.10         Further Assurances. Borrower will execute and deliver or cause to
be executed and delivered such other and further instruments or documents and take such further action as in the judgment of Administrative Agent may be required to carry out the provisions and purposes of the Loan Papers including without
limitation to create, preserve, protect and perfect the Liens of the Administrative Agent for the ratable benefit of the Banks as required by Section 6.1.
          
SECTION 9.11         Environmental Law Compliance and Indemnity. Borrower will, and

Laws, and (b) all provisions of Applicable Environmental Law regarding storage, discharge, release, transportation, treatment and disposal of hazardous substances, petroleum, solid waste or other contaminants. Borrower will, and will cause each
of its Subsidiaries to, promptly pay and discharge when due all debts, claims, liabilities and obligations with respect to any clean-up or remediation measures necessary to comply with Applicable Environmental Laws. Borrower hereby indemnifies and
agrees to defend and hold Banks and their successors and assigns harmless from and against any and all claims, demands, causes of action, loss, damage, liabilities, costs and expenses (including reasonable attorneys’ fees and court costs) of
any and every kind or character, known or unknown, fixed or contingent, asserted against or incurred by any of the Banks at any time and from time to time including, without limitation, those asserted or arising subsequent to the payment or other
satisfaction of the Loan, by reason of or arising out of the ownership, construction, occupancy, operation, use and maintenance of any of the collateral for the Loan, including matters arising out of the negligence of Banks; provided, however, this indemnity shall not apply with respect to matters caused by or arising out of (i) the gross negligence or willful misconduct of Banks (IT
BEING THE EXPRESS INTENTION HEREBY THAT BANKS SHALL BE INDEMNIFIED FROM THE CONSEQUENCES OF THEIR NEGLIGENCE); and (ii) the construction, occupancy, operation, use and maintenance of the collateral for the Loan by any owner, lessee or party in
possession of the collateral for the Loan subsequent to the ownership of the collateral for the Loan by Borrower or any of its Subsidiaries (as applicable), provided further, however, that this subclause (ii) shall not exclude from the foregoing
indemnity and agreement, liability, claims, demands, causes of action, loss, damage, costs and expenses imposed by reason of the ownership of the collateral for the Loan by Banks after purchase by Banks at any foreclosure sale or transfer in lieu
thereof from Borrower or any Restricted Subsidiary in partial or entire satisfaction of the Loan (unless the same shall be solely attributable to the subsequent use of the collateral by Banks during their ownership thereof). The foregoing indemnity
and agreement applies to the violation of any Applicable Environmental Law prior to the payment or other satisfaction of the Loan and any act, omission, event or circumstance existing or occurring on or about the collateral for the Loan (including
without 
 48

 
 limitation the presence on the collateral for the Loan or release from the collateral for the Loan of asbestos or other hazardous substances or solid waste disposed of or otherwise
present in or released prior to the payment or other satisfaction of the Loan). It shall not be a defense to the covenant of Borrower to indemnify that the act, omission, event or circumstance did not constitute a violation of any Applicable
Environmental Law at the time of its existence or occurrence. The provisions of this Section 9.11 shall survive the repayment of the Loan and shall continue thereafter in full force and effect. In
the event of the transfer of the Loan or any portion thereof, Banks or any prior holder of the Loan and any participants shall continue to be benefited by this indemnity and agreement with respect to the period of such holding of the
Loan.

cure period as is provided pursuant to the terms of such Material Debt) which entitles (or, with the giving of notice or lapse of time or both, would unless cured or waived, entitle) the holder of such Material Debt to accelerate the maturity
thereof;
                   (h)         any Company shall
commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a
trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other
proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or shall take any corporate action to authorize any of the foregoing; 
                   (i)         an involuntary case or other proceeding
shall be commenced against any Company seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee,

                   (j)         one (1) or more judgments or orders for the payment of money aggregating in excess of $2,000,000 shall be rendered against any Company and such judgment or order
(i) shall continue unsatisfied and unstayed (unless bonded with a supersedeas bond at least equal to such judgment or order) for a period of thirty (30) days or (ii) is not fully paid and satisfied at least ten (10) days prior to the date

insurance to the satisfaction of Administrative Agent and its counsel, and (B) any amounts which Borrower or any of its Restricted Subsidiaries has deposited with Administrative Agent to be held by Administrative Agent as security for the
payment of such judgment shall be rendered against Borrower or any of its Subsidiaries, whether or not otherwise bonded or stayed;
                   (l)         any Company shall incur Environmental
Liabilities which, individually or when considered in the aggregate for all Companies, exceeds $10,000,000;
                   (m)         this Agreement or any other Loan Paper shall cease to be in full force and effect or shall be declared null and void or the validity or enforceability thereof shall
be contested or challenged by Borrower or any Restricted Subsidiary of Borrower, or Borrower or any Restricted Subsidiary of Borrower shall deny that it has any further liability or obligation under any of the Loan Papers, or any Lien created by the
Loan Papers shall for any reason (other than the release thereof in accordance with the Loan Papers) cease to be a valid, first priority, perfected Lien upon any of the property purported to be covered thereby; and
                   (n)         any Person or group (as defined in
Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934) shall become the direct or indirect beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of more than thirty percent (30%) of the total
voting power of all classes of capital stock then outstanding of Borrower entitled (without regard to the occurrence of any contingency) to vote in elections of directors of Borrower;
 then, and in every such
event, Administrative Agent shall without presentment, notice or demand (unless expressly provided for herein) of any kind (including, without limitation, notice of intention to accelerate and acceleration), all of which are hereby waived,
(a) if requested by Required Banks, terminate the Commitment and it shall thereupon terminate, and (b) if requested by Required Banks, take such other actions as may be permitted by the Loan Papers including, declaring the Obligations, or
any portion thereof (together with accrued interest thereon) to be, and the Obligations, or any portion thereof, shall thereupon become, immediately due and payable; provided that in the case of any of the Events of Default specified in Section 12.1(h) or Section 12.1(i), without any

payable.
 ARTICLE XIII
AGENTS
          
SECTION 13.1         Appointment; Nature of Relationship. Bank One, NA is hereby appointed
by each of the Banks as its contractual representative and Administrative Agent hereunder and under each other Loan Paper, and each Bank irrevocably authorizes Administrative Agent to act as the contractual representative of such Bank with the
rights and duties expressly set forth herein and in the other Loan Papers. Administrative Agent agrees to act as such contractual representative and Administrative Agent upon the express conditions
 54

 
 contained in this Article XIII. 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 Bank by reason of this Agreement or any other Loan Paper and that Administrative Agent is
merely acting as the contractual representative of the Banks with only those duties as are expressly set forth in this Agreement and the other Loan Papers. In its capacity as the Banks’ contractual representative, Administrative Agent
(i) does not hereby assume any fiduciary duties to any of the Banks, (ii) is a “representative” of the Banks 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 Papers. Each of the Banks hereby agrees to assert no claim against Administrative Agent
on any theory of liability for breach of fiduciary duty, any and all of which claims each Bank hereby waives.
          
SECTION 13.2         Powers. Administrative Agent shall have and may exercise such powers
under the Loan Papers 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 Banks, or any
obligation to the Banks to take any action thereunder except any action specifically provided by the Loan Papers to be taken by Administrative Agent.
          
SECTION 13.3         General Immunity. Neither Administrative Agent nor any of its
directors, officers, agents or employees shall be liable to Borrower or any Bank for any action taken or omitted to be taken by it or them hereunder or under any other Loan Paper 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.
          
SECTION 13.4         No Responsibility for Loans, Recitals, etc. Neither Administrative
Agent nor any of its 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 Paper or any Borrowing
hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Paper, including, without limitation, any agreement by an obligor to furnish information directly to each Bank; (c) the
satisfaction of any condition specified in Section 7.1 hereof, except receipt of items required to be delivered solely to Administrative Agent; (d) the existence or possible existence of any
Default or Event of Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Paper 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 Borrower or any guarantor of any of the Obligations or of any of Borrower’s or any such guarantor’s respective Subsidiaries.
Administrative Agent shall have no duty to disclose to the Banks information that is not required to be furnished by Borrower to Administrative Agent at such time, but is voluntarily furnished by Borrower to Bank One (either in its capacity as
Administrative Agent or in its individual capacity).
          
SECTION 13.5         Action on Instructions of Banks. Administrative Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder and under any other
 55

 
 Loan Paper in accordance with written instructions signed by the Required Banks, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of
the Banks. The Banks 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 Paper unless it shall be requested
in writing to do so by Required Banks. Administrative Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Paper unless it shall first be indemnified to its satisfaction by the Banks pro rata
against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.
          
SECTION 13.6         Employment of Agents and Counsel. Administrative Agent may execute any
of its duties as Administrative Agent hereunder and under any other Loan Paper by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, 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 Banks
and all matters pertaining to Administrative Agent’s duties hereunder and under any other Loan Paper.
          
SECTION 13.7         Reliance on Documents; Counsel. Administrative Agent shall be entitled
to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document 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.
          
SECTION 13.8         Administrative Agent’s Reimbursement and Indemnification. Banks
agree to reimburse and indemnify Administrative 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 Administrative Agent is entitled to reimbursement by Borrower under the Loan Papers, (ii) for any other expenses incurred by Administrative Agent on behalf of the Banks, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan Papers (including, without limitation, for any expenses incurred by Administrative Agent in connection with any dispute between Administrative Agent and any Bank or between
two or more of the Banks) 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 Administrative Agent in any way relating to or arising out of the Loan Papers 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 Administrative Agent in connection with any dispute between Administrative Agent and any Bank or between two or more of the Banks), or the enforcement of any of the terms of the Loan Papers or of any such other documents;
provided that, no Bank 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 Administrative Agent. The obligations of the Banks under this Section 13.8 shall survive payment
of the Obligations and termination of this Agreement.
 56

 
          
SECTION 13.9         Notice of Default . Administrative Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default hereunder unless Administrative Agent has received written notice from a Bank or Borrower referring to this Agreement describing such Default or Event of 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 Banks.
          
SECTION 13.10         Rights as a Bank. In the event Administrative Agent is a Bank, Administrative Agent shall have
the same rights and powers hereunder and under any other Loan Paper with respect to its Commitment and its Loans as any Bank and may exercise the same as though it were not Administrative Agent, and the term “Bank” or “Banks” shall, at
any time when Administrative Agent is a Bank, unless the context otherwise indicates, include Administrative Agent in its individual capacity. Administrative Agent and its 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 Paper, with Borrower or any of its Subsidiaries in which Borrower or such Subsidiary is not restricted hereby from engaging
with any other Person. 
          
SECTION 13.11         Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance
upon Administrative Agent, Sole Lead Arranger, Book Manager or any other Agent or Bank 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 Papers. Each Bank also acknowledges that it will, independently and without reliance upon Administrative Agent, Sole Lead Arranger, Book Manager or any other Agent or Bank 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 Papers.
          
SECTION 13.12         Successor Administrative Agent. Administrative Agent may resign at any time by giving written
notice thereof to Banks 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 Required Banks, such removal to be effective on the date specified by Required
Banks. Upon any such resignation or removal, Required Banks shall have the right to appoint, on behalf of Borrower and the Banks, a successor Administrative Agent, which shall be approved by Borrower, such approval not to be unreasonably withheld;
provided, that, Borrower shall not have the right to approve any successor Administrative Agent appointed during the continuance of any Default. If no
successor Administrative Agent shall have been so appointed by Required Banks 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 Banks, a successor Administrative Agent which shall be approved by Borrower, such approval not to be unreasonably withheld; provided, that, Borrower shall not have the right to approve any successor Administrative Agent appointed during the continuance of any Default. If Administrative Agent has resigned or been removed and no successor Administrative Agent has been appointed,
Banks may perform all the duties of Administrative Agent hereunder and
 57

 
 Borrower shall make all payments in respect of the Obligations to the applicable Bank and for all other purposes shall deal directly with the Banks. No successor Administrative Agent
shall be deemed to be appointed hereunder until such successor Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. 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 Administrative Agent, the resigning or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the Loan
Papers. After the effectiveness of the resignation or removal of an Administrative Agent, the provisions of this Article XIV 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 Papers. In the event that there is a successor to Administrative Agent by merger, or Administrative Agent
assigns its duties and obligations to an Affiliate pursuant to this Section 13.12, then the term “Base Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Administrative Agent.
          
SECTION 13.13         Delegation to Affiliates. Borrower and Banks agree that Administrative Agent may delegate any of
its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which Administrative Agent is entitled under Article XIII and Article XIV.

         
SECTION 13.14         Execution of Collateral Documents. Without limiting the powers and authority of Administrative
Agent described herein, the Banks hereby empower and authorize Administrative Agent to execute and deliver to Borrower on their behalf the Certificate of Effectiveness, the Mortgages, the Assignments and Amendments to Mortgages, the Restricted
Subsidiary Pledge Agreements (as applicable) and all related financing statements and any other financing statements, agreements, documents or instruments as shall be necessary or appropriate to effect the purposes of the foregoing
instruments.
          
SECTION 13.15         Collateral Releases. Banks hereby empower and authorize Administrative Agent to execute and
deliver to Borrower on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of collateral which shall be permitted by the terms hereof or of any other Loan Paper or which shall otherwise
have been approved by Required Banks (or, if required by the terms of Section 15.5, all of the Banks) in writing.
          
SECTION 13.16         Agents. None of the Banks identified in this Agreement as a “Documentation Agent”
and/or a “Syndication Agent” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Banks as such. Without limiting the foregoing, none of such Documentation
Agents or Syndication Agents shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the same acknowledgments with respect to such Documentation Agents and Syndication Agents as it makes with respect to
Administrative Agent in Section 13.11.
 58

  ARTICLE XIV
CHANGE IN CIRCUMSTANCES
           
SECTION 14.1      Increased Cost and Reduced Return.
                   (a)         If, after the date hereof, the adoption
of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its applicable Lending Office) with any request or directive (whether or not having the force of law) of any such governmental authority, central bank, or comparable
agency:

	 	            (i)      shall subject such Bank (or its applicable Lending Office) to any tax, duty, or other charge with
respect to any Eurodollar Tranches, its Note, or its obligation to make Loans comprised of Eurodollar Tranches, or change the basis of taxation of any amounts payable to such Bank (or its applicable Lending Office) under this Agreement or its Note
in respect of any Eurodollar Tranches (other than taxes imposed on the overall net income of such Bank or such applicable Lending Office);

	 	            (ii)    shall impose, modify, or deem applicable any reserve, special deposit, assessment, compulsory loan, or similar
requirement (other than the Eurodollar Reserve Percentage utilized in the determination of the Adjusted Eurodollar Rate) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Bank
(or its applicable Lending Office), including the Commitment of such Bank hereunder; or 

	 	            (iii)   shall impose on such Bank (or its applicable Lending Office) or on the London interbank market any other condition
affecting this Agreement or its Note or any of such extensions of credit or liabilities or commitments; 

 and the result of any of the foregoing is to increase the cost to such Bank (or its
applicable Lending Office) of making, converting into, continuing, or maintaining any Eurodollar Tranches or to reduce any sum received or receivable by such Bank (or its applicable Lending Office) under this Agreement or its Note with respect to
any Eurodollar Tranches, then the Borrower shall pay to such Bank on demand such amount or amounts as will compensate such Bank for such increased cost or reduction. If any Bank requests compensation by Borrower under this Section 14.1(a), the Borrower may, by notice to such Bank (with a copy to Administrative Agent), suspend the obligation of such Bank to make or continue Eurodollar Tranches or to convert all or part of the Base
Rate Tranche owing to such Bank into Eurodollar Tranches, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 14.4 shall be
applicable); provided, that such suspension shall not affect the right of such Bank to receive the compensation so requested.
                   (b)         If, after the date hereof, any Bank
shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency
charged with the interpretation or administration thereof, or any request or
 59

 
 directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency, has or would have the effect of
reducing the rate of return on the capital of such Bank or any corporation controlling such Bank as a consequence of such Bank’s obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such
adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then, from time to time upon demand, Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank
for such reduction. 
                   (c)         Each
Bank shall promptly notify Borrower and Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section 14.1 and will designate a different applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be
otherwise disadvantageous to it. Any Bank claiming compensation under this Section 14.1 shall furnish to Borrower and Administrative Agent a statement setting forth the additional amount or amounts
to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. 
          
SECTION 14.2         Limitation on Type of Loans. If on or prior to the first day of any Interest Period for any
Eurodollar Tranche:
                   (a)         Administrative Agent determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period;
or
                   (b)         Required Banks
determine (which determination shall be conclusive) and notify Administrative Agent that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to Banks of funding Eurodollar Tranches for such Interest Period;
 then Administrative Agent shall give Borrower prompt notice thereof specifying the relevant Type of Loans and the relevant amounts or periods, and so long as such condition remains in effect, Banks shall be under no
obligation to make additional Loans of such Type, continue Loans of such Type, or to convert Loans of any other Type into Loans of such Type, and Borrower shall, on the last day(s) of the then current Interest Period(s) for the outstanding Loans of
the affected Type, either prepay such Loans or convert such Loans into another Type of Loan in accordance with the terms of this Agreement.
          
SECTION 14.3         Illegality. Notwithstanding any other provision of this Agreement, in
the event that it becomes unlawful for any Bank or its applicable Lending Office to make, maintain, or fund Eurodollar Tranches hereunder, then such Bank shall promptly notify Borrower thereof and such Bank’s obligation to make or continue
Eurodollar Tranches and to convert other Types of Loans into Eurodollar Tranches shall be suspended until such time as such Bank may again make, maintain, and fund Eurodollar Tranches (in which case the provisions of Section 14.4 shall be applicable).
 60

 
          
SECTION 14.4         Treatment of Affected Loans. If the obligation of any Bank to make particular Eurodollar Tranches
or to continue Loans, or to convert Loans of another Type into Loans of a particular Type shall be suspended pursuant to Section 14.1 or Section 14.3 hereof (Loans of such Type being herein called “Affected Loans” and such Type being herein called the “Affected Type”), such Bank’s Affected Loans shall be automatically converted into the Adjusted Base Rate Tranche on the last day(s) of the
then current Interest Period(s) for Affected Loans (or, in the case of a conversion required by Section 14.3 hereof, on such earlier date as such Bank may specify to Borrower with a copy to
Administrative Agent) and, unless and until such Bank gives notice as provided below that the circumstances specified in Section 14.1 or Section 14.3 hereof that gave rise to such conversion no longer exist:
                   (a)         to the extent that such Bank’s Affected Loans have been so converted, all payments and prepayments of principal that would otherwise be applied to such
Bank’s Affected Loans shall be applied instead to the Adjusted Base Rate Tranche; and
                   (b)         all Loans that would otherwise be made or continued by such Bank as Loans of the Affected Type shall be made or continued instead as part of the Adjusted Base Rate
Tranche, and all Loans of such Bank that would otherwise be converted into Loans of the Affected Type shall be converted instead into (or shall remain) as part of the Adjusted Base Rate Tranche.
 If such Bank
gives notice to Borrower (with a copy to Administrative Agent) that the circumstances specified in Section 14.1 or Section 14.3 hereof that gave
rise to the conversion of such Bank’s Affected Loans pursuant to this Section 14.4 no longer exist (which such Bank agrees to do promptly upon such circumstances ceasing to exist) at a time
when Loans of the Affected Type made by other Banks are outstanding, such Bank’s portion of the Adjusted Base Rate Tranche shall be automatically converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding
Loans of the Affected Type, to the extent necessary so that, after giving effect thereto, all Loans held by Banks holding Loans of the Affected Type and by such Bank are held pro rata (as to principal amounts, Types and Interest Periods) in
accordance with their respective Commitments.
          
SECTION 14.5         Compensation. Upon the request of any Bank, Borrower shall pay to such Bank such amount or
amounts as shall be sufficient (in the reasonable opinion of such Bank) to compensate it for any loss, cost, or expense (including loss of anticipated profits) incurred by it as a result of:
                   (a)         any payment, prepayment, or conversion
of a Eurodollar Tranche for any reason (including, without limitation, the acceleration of the Loan) on a date other than the last day of the Interest Period for such Loan; or
                   (b)         any failure by the Borrower for any
reason (including, without limitation, the failure of any condition precedent specified in Article VII to be satisfied) to borrow, convert, continue, or prepay a Eurodollar Tranche on the date for such
Borrowing, conversion, continuation, or prepayment specified in the relevant Request for Borrowing, Rollover Notice, or other notice of Borrowing, prepayment, continuation, or conversion under this Agreement.
 61

 
          
SECTION 14.6         Taxes.
                   (a)         Any and all payments by Borrower to or
for the account of any Bank or Administrative Agent hereunder or under any other Loan Paper shall be made free and clear of and without deduction for any and all present or future Taxes, duties, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of each Bank and Administrative Agent, Taxes imposed on its income, and franchise Taxes imposed on it, by the jurisdiction under the laws
of which such Bank (or its applicable Lending Office) or Administrative Agent (as the case may be) is organized or any political subdivision thereof (all such non-excluded Taxes, duties, levies, imposts, deductions, charges, withholdings, and
liabilities being hereinafter referred to in this Section 14.6 as “Non-Excluded Taxes”). If Borrower shall be required by law to deduct any Non-Excluded Taxes from or in respect of any sum payable under this Agreement or any other Loan Paper to any Bank or Administrative Agent, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 14.6) such Bank or Administrative Agent receives an amount
equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with
applicable law, and (iv) Borrower shall furnish to Administrative Agent, at its address set forth on Schedule 2.1 hereto, the original or a certified copy of a receipt evidencing payment
thereof.
                   (b)         In addition,
Borrower agrees to pay any and all present or future stamp or documentary Taxes and any other excise or property Taxes or charges or similar levies which arise from any payment made under this Agreement or any other Loan Paper or from the execution
or delivery of, or otherwise with respect to, this Agreement or any other Loan Paper (hereinafter referred to as “Other Taxes”).
                   (c)         Borrower agrees
to indemnify each Bank and Administrative Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 14.6) paid by such Bank or Administrative Agent (as the case may be) and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto.
                   (d)         Each Bank organized under the laws of a
jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on Schedule 2.1 hereto and on or prior to the date on
which it becomes a Bank in the case of each other Bank, and from time to time thereafter if requested in writing by Borrower or Administrative Agent (but only so long as such Bank remains lawfully able to do so), shall provide Borrower and
Administrative Agent, at the time or times prescribed by applicable law, with such properly completed and executed documentation prescribed by applicable law (or reasonably requested by Borrower) certifying that such Bank is entitled to benefits
under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a
trade or business in the United States, and certifying that such Bank is entitled to an exemption from or a reduced rate of tax on payments pursuant to this Agreement or any of the other Loan Papers.
 62

 
                    (e)         For any period with respect to which a Bank has failed to provide Borrower and Administrative Agent with the appropriate form pursuant to Section 14.6(d) (unless such failure is due to a
change in treaty, law, or regulation occurring subsequent to the date on which a form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 14.6(a) or Section 14.6(b) with respect to Non-Excluded Taxes imposed by the United States; provided, however, that should a Bank, which is otherwise exempt from or subject to a reduced rate of withholding Tax, become subject to Non-Excluded Taxes because of its failure to deliver a form required hereunder, Borrower shall take such steps as such
Bank shall reasonably request to assist such Bank to recover such Non-Excluded Taxes.
                   (f)         If Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 14.6, then such Bank will agree to use reasonable efforts to change the jurisdiction of its applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such
Bank, is not otherwise disadvantageous to such Bank.
                   (g)         Within thirty (30) days after the date of any payment of Non-Excluded Taxes, Borrower shall furnish to Administrative Agent the original or a certified copy of a
receipt evidencing such payment.
                   (h)         Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 14.6 shall survive the termination of the
Commitments and the payment in full of the Notes.
          
SECTION 14.7         Discretion of Banks as to Manner of Funding. Notwithstanding any provisions of this Agreement to
the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Commitment in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be
made as if such Bank had actually funded and maintained each Eurodollar Tranche during the Interest Period for such Eurodollar Tranche through the purchase of deposits having a maturity corresponding to the last day of such Interest Period and
bearing an interest rate equal to the Adjusted Eurodollar Rate for such Interest Period.

SECTION 15.3         Expenses; Documentary Taxes; Indemnification.
                   (a)         Borrower agrees to pay on demand all
reasonable costs and expenses of each Agent (other than any Documentation Agent or Syndication Agent) in connection with the syndication, preparation, execution, delivery, modification, and amendment of this Agreement, the other Loan Papers, and the
other documents to be delivered hereunder, including, without limitation, the reasonable fees and expenses of counsel for Administrative Agent with respect thereto and with respect to advising Administrative Agent as to its rights and

enforcement (whether through negotiations, legal proceedings, or otherwise) of the Loan Papers and the other documents to be delivered hereunder.
                   (b)         BORROWER AGREES TO INDEMNIFY
AND HOLD HARMLESS EACH AGENT AND EACH BANK AND EACH OF THEIR AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND ADVISORS (EACH, AN “INDEMNIFIED PARTY”)
FROM AND AGAINST ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS, AND EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS’ FEES) THAT MAY BE INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE
ARISING OUT OF OR IN CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN CONNECTION THEREWITH) THE LOAN PAPERS, ANY OF THE TRANSACTIONS
CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE LOAN (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE IS FOUND
IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH INDEMNIFIED PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. IN THE CASE OF AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE
INDEMNITY IN THIS SECTION 15.3 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY CREDIT PARTIES, ITS DIRECTORS,
SHAREHOLDERS OR CREDITORS OR AN
 64

 
 INDEMNIFIED PARTY OR ANY OTHER PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. BORROWER AGREES
NOT TO ASSERT ANY CLAIM AGAINST ANY AGENT, ANY BANK, ANY OF THEIR AFFILIATES, OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS, AGENTS, AND ADVISERS, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE
DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE LOAN PAPERS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE LOAN.
                   (c)         Without prejudice to the survival of any
other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 15.3 shall survive the payment in full of the Loan and all other amounts payable under
this Agreement. 
          
SECTION 15.4         Right and Sharing of Set-Offs.
                   (a)         Upon the occurrence and during the
continuance of any Event of Default, each Bank is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Bank to or for the credit or the account of Borrower against any and all of the obligations of Borrower now or hereafter existing under this Agreement and any Note held by such Bank,
irrespective of whether or not such Bank shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Bank agrees promptly to notify Borrower after any such setoff and application made by such
Bank, provided that the failure to give such notice shall not affect the validity of such setoff and application. The rights of each Bank under this Section 15.4(a) are in addition to other rights
and remedies (including, without limitation, other rights of setoff) which such Bank may have.
                   (b)         Each Bank agrees that if it shall, by exercising any right of setoff or counterclaim or otherwise, receive payment after the occurrence and during the continuance of
an Event of Default of a proportion of the aggregate amount of principal and interest due with respect to the Loan which is greater than the proportion received by any other Bank in respect of the Loan, the Bank receiving such proportionately
greater payment shall purchase such participations in the interests in the Loan held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Loan held
by Banks shall be shared by Banks ratably in accordance with their respective Commitment Percentages; provided that nothing in this Section 15.4(b) shall impair the right of any Bank to exercise any right of setoff or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of Borrower other than
its indebtedness under the Loan. Borrower agrees, to the fullest extent it may effectively do so under applicable law, that Participants may exercise rights of setoff or counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of Borrower in the amount of such participation.
 65

 
          
SECTION 15.5         Amendments and Waivers. Subject to Section 15.10(f), any provision of this Agreement, the Notes or the other Loan Papers may be amended or waived if, but only if such amendment or waiver is in writing and is signed by Borrower and Required Banks (and, if the rights or duties of any Agent are
affected thereby, by such Agent); providedthat no such amendment or waiver shall, unless signed by all Banks, (a) increase the Commitment of any Bank
or subject any Bank to any additional obligation, (b) forgive any of the principal of or reduce the rate of interest on the Loan or any fees hereunder, (c) postpone the date fixed for any payment of principal of or interest on the Loan or
any fees hereunder including the Termination Date, (d) change the percentages of the Total Commitment, or the number of Banks which shall be required for the Banks or any of them to take any action under this Section 15.5 or any other provision of this Agreement, (e) permit Borrower to assign any of its rights hereunder, (f) amend or waive any of the provisions of Article V or the definitions contained in Section 2.1 applicable thereto, (g) provide for release or substitution of collateral for the Obligations or any
part thereof other than releases required pursuant to sales of collateral which are expressly permitted by Section 10.5 hereof, or (h) amend, modify or waive any provision of this
Section 15.5. Borrower, Agent and each Bank further acknowledge that any decision by any Agent or any Bank to enter into any amendment, waiver or consent pursuant hereto shall be made by such Bank
or Agent in its sole discretion, and in making any such decision each such Agent and each such Bank shall be permitted to give due consideration to any credit or other relationship any such Agent or any such Bank may have with Borrower, any
Affiliate of Borrower, or any other Unrestricted Subsidiary of Borrower.
          
SECTION 15.6         Survival. All representations, warranties and covenants made by Borrower herein or in any
certificate or other instrument delivered by it or in its behalf under the Loan Papers shall be considered to have been relied upon by Banks and shall survive the delivery to Banks of such Loan Papers or the extension of the Loan (or any part
thereof), regardless of any investigation made by or on behalf of Banks.
          
SECTION 15.7         Limitation on Interest. Regardless of any provision contained in the
Loan Papers, Banks shall never be entitled to receive, collect, or apply, as interest on the Loan, any amount in excess of the Maximum Lawful Rate, and in the event Banks ever receive, collect or apply as interest any such excess, such amount which
would be deemed excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such; and if the Loan is paid in full, any remaining excess shall promptly be paid to Borrower. In determining whether or not the interest
paid or payable under any specific contingency exceeds the Maximum Lawful Rate, Borrower and Banks shall, to the extent permitted under applicable law, (a) characterize any non-principal payment as an expense, fee or premium rather than as
interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate and spread, in equal parts, the total amount of the interest throughout the entire contemplated term of the applicable Notes, so that
the interest rate is the Maximum Lawful Rate throughout the entire term of the Notes; provided, however, that if the unpaid principal balance thereof is
paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Lawful Rate, Banks shall refund to Borrower the amount of such excess and,
in such event, Banks shall not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Lawful Rate.
 66

 
          
SECTION 15.8         Invalid Provisions. If any provision of the Loan Papers is held to be
illegal, invalid, or unenforceable under present or future laws effective during the term thereof, such provision shall be fully severable, the Loan Papers shall be construed and enforced as if such illegal, invalid, or unenforceable provision had
never comprised a part thereof, and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such
illegal, invalid, or unenforceable provision there shall be added automatically as a part of the Loan Papers a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and
enforceable.
          
SECTION 15.9         Waiver of Consumer Credit Laws. Pursuant to Chapter 346 of the Texas Finance Code, as amended,
Borrower agrees that such Chapter 346 shall not govern or in any manner apply to the Loan.
          
SECTION 15.10         Assignments and Participations.
                   (a)         Successors and
Assigns. The terms and provisions of the Loan Papers shall be binding upon and inure to the benefit of Borrower and Banks and their respective successors and assigns permitted hereby, except that (i) Borrower shall
not have the right to assign its rights or obligations under the Loan Papers without the prior written consent of each Bank, (ii) any assignment by any Bank must be made in compliance with Section 15.10(c), and (iii) any transfer by participation must be made in compliance with Section 15.10(b). Any attempted assignment or transfer by any
party not made in compliance with this Section 15.10(a) shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 15.10(b). The parties to this Agreement acknowledge that clause (ii) of this Section 15.10(a) relates only to absolute assignments and this
Section 15.10(a) does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Bank of all or any portion of its rights under
this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Bank which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to
its trustee; provided, however, that no such pledge or assignment creating a security interest shall release
the transferor Bank from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 15.10(c). Administrative Agent may treat the Person which made
any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 15.10(c); provided,
however, that Administrative Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which
holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Papers. Any
request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and
binding on any subsequent holder or assignee of the rights to such Loan.
 67

 
                    (b)         Participations. 

	 	         (i)      Any Bank may at any time sell to one or more banks or other entities (“Participant”) participating interests in any Loan owing to such Bank, any Note held by such Bank, any Commitment of such Bank or any other interest of such
Bank under the Loan Papers. In the event of any such sale by a Bank of participating interests to a Participant, (A) such Bank’s obligations under the Loan Papers shall remain unchanged, (B) such Bank shall remain solely responsible
to the other parties hereto for the performance of such obligations, (C) such Bank shall remain the owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Papers, (D) all amounts
payable by Borrower under this Agreement shall be determined as if such Bank had not sold such participating interests, and (E) Borrower and Administrative Agent shall continue to deal solely and directly with such Bank in connection with such
Bank’s rights and obligations under the Loan Papers.

	 	         (ii)    Each Bank shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of
any provision of the Loan Papers other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which would require consent of all of the Banks pursuant to the terms of
Section 15.5 or of any other Loan Paper.

	 	         (iii)   Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 15.4 in respect of its participating interest in amounts owing under the Loan Papers to the same extent as if the amount of its participating interest were owing directly to it as a Bank under the Loan
Papers; provided, that each Bank shall retain the right of setoff provided in Section 15.4 with respect
to the amount of participating interests sold to each Participant. Banks agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 15.4,
agrees to share with each Bank, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 15.4 as if each Participant were a Bank.
Borrower further agrees that each Participant shall be entitled to the yield protection provisions contained in Article XIV to the same extent as if it were a Bank and had acquired its interest by
assignment pursuant to Section 15.10(c); provided, that (A) a Participant shall not be entitled to
receive any greater payment under Article XIV than the Bank who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the
sale of such interest to such Participant is made with the prior written consent of Borrower, and (B) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of
Section 14.6 to the same extent as if it were a Bank.

                   (c)         Assignments.

	 	         (i)      Any Bank may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Loan Papers. The parties to such assignment shall execute and deliver an Assignment and Acceptance 

68

 

	 		Agreement (herein so called) which shall be substantially in the form of Exhibit G or in such other form as may be agreed to by the parties thereto. Each such assignment
with respect to a Purchaser which is not a Bank or an Affiliate of a Bank or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Loans of the assigning Bank or (unless each of Borrower and Administrative Agent
otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or outstanding Loans (if the Commitment has been terminated) subject to the assignment, determined as of the date
of such assignment or as of the “Effective Date,” if the “Effective Date” is specified in the Assignment and Acceptance Agreement.

	 	         (ii)    The consent of Borrower shall be required prior to an assignment becoming effective unless Purchaser is a Bank, an Affiliate of a
Bank or an Approved Fund, provided that the consent of Borrower shall not be required if a Default has occurred and is continuing. The consent of Administrative Agent shall be required prior to an assignment becoming effective unless the Purchaser
is a Bank, an Affiliate of a Bank or an Approved Fund. The consent of Letter of Credit Issuer shall be required prior to an assignment of a Commitment becoming effective unless Purchaser is a Bank, an Affiliate of a Bank or an Approved Fund. Any
consent required under this Section 15.10(c)(ii) shall not be unreasonably withheld or delayed.

	 	         (iii)   Upon (A) delivery to Administrative Agent of an Assignment and Acceptance Agreement, together with any consents required by
Section 15.10(c)(i) and (ii), and (B) payment of a $3,500 fee to Administrative Agent for processing such assignment (unless such fee is waived
by Administrative Agent), such assignment shall become effective on the effective date specified in such Assignment and Acceptance Agreement. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Bank party
to this Agreement and any other Loan Paper executed by or on behalf of Banks and shall have all the rights and obligations of a Bank under the Loan Papers, to the same extent as if it were an original party thereto, and the transferor Bank shall be
released with respect to the Commitment and Loans assigned to such Purchaser without any further consent or action by Borrower, Banks or Administrative Agent. In the case of an assignment covering all of the assigning Bank’s rights and
obligations under this Agreement, such Bank shall cease to be a Bank hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Papers which survive payment of the
Obligations and termination of the applicable agreement. Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this Section 15.10(c) shall be
treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with Section 15.10(b). Upon the consummation of any assignment to a
Purchaser pursuant to this Section 15.10(c), the transferor Bank, Administrative Agent and Borrower shall make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are
issued to such transferor Bank and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment. In addition, within
a reasonable period of time after the effective date of any assignment to a Purchaser pursuant to this Section 15.10(c), Administrative Agent shall, 

 69

 

	 	and is hereby authorized and directed to, revise Schedule 2.1 to reflect such assignment and shall distribute such revised Schedule 2.1 to each of the Banks and Borrower, whereupon such revised Schedule 2.1 shall replace the old Schedule 2.1 and become a part of this Agreement.	

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

                   (d)         Dissemination of Information. Borrower authorizes each Bank to disclose to any Participant or Purchaser or any other Person
acquiring an interest in the Loan Papers by operation of law, or any actual or proposed contractual counterparty (or its advisors) to any securitization, hedge or other derivative transaction relating to a party’s obligations hereunder (each a
“Transferee”) and any prospective Transferee any and all information in such Bank’s possession concerning the creditworthiness of Borrower and its Subsidiaries, including, without
limitation, any information contained in any financial reports; provided, that, each Transferee and prospective Transferee agrees to be bound by
Section 15.17 of this Agreement.
                   (e)         Tax Treatment. If any interest in any Loan Paper is transferred to any Transferee which is not incorporated under the laws of the
United States or any State thereof, the transferor Bank shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 14.6(d).
                   (f)         Procedures
for Increases and Addition of New Banks. This Agreement permits certain increases of a Bank’s Commitment and the admission of new Banks providing new Commitments, none of which requires any consent or approvals from
the other Banks. Any amendment hereto for such an Increase or addition shall be in the form attached hereto as Exhibit K and shall only require the written signatures of Administrative Agent, Borrower
and the Bank(s) being added or increasing their Commitment. On the effective date of any such Increase, Administrative Agent, Borrower and applicable Banks shall make appropriate arrangements so that new Notes or, as appropriate, replacement Notes
are issued to the applicable Banks, in each case in principal amounts reflecting their respective Commitments, after giving effect to such Increase. In addition, within a reasonable period of time after the effective date of any Increase,
Administrative Agent shall, and is hereby authorized and directed to, revise Schedule 2.1 to reflect such Increase and shall distribute such revised Schedule 2.1 to each of the Banks and Borrower, whereupon such revised Schedule 2.1 shall replace the old Schedule 2.1 and become part of this Agreement. On the
first Domestic Business Day immediately following any such Increase, all outstanding Adjusted Base Rate Tranches shall be reallocated among the Banks (including any newly added Bank(s)) in accordance with the 
 70

 
 Banks’ respective revised pro rata shares of such outstanding Tranches. Eurodollar Tranches shall not be reallocated among the Banks prior to the expiration of the applicable
Interest Periods in effect at the time of any such Increase.
          
SECTION 15.11         TEXAS LAW. THIS AGREEMENT, EACH NOTE AND THE OTHER LOAN PAPERS SHALL BE CONSTRUED IN ACCORDANCE WITH
AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, EXCEPT TO THE EXTENT THAT THE LAWS OF ANY STATE IN WHICH ANY PROPERTY INTENDED AS SECURITY FOR THE OBLIGATIONS IS LOCATED NECESSARILY GOVERN (A) THE
PERFECTION AND PRIORITY OF THE LIENS IN FAVOR OF ADMINISTRATIVE AGENT AND BANKS WITH RESPECT TO SUCH PROPERTY, AND (B) THE EXERCISE OF ANY REMEDIES (INCLUDING FORECLOSURE) WITH RESPECT TO SUCH PROPERTY.
          
SECTION 15.12         Consent to Jurisdiction; Waiver of Immunities.
                   (a)         Borrower hereby irrevocably submits to
the jurisdiction of any Texas State or Federal court sitting in the Northern District of Texas over any action or proceeding arising out of or relating to this Agreement or any other Loan Papers, and Borrower hereby irrevocably agrees that all
claims in respect of such action or proceeding may be heard and determined in such Texas State or Federal court. Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such
process to Borrower at its address specified in Section 15.1. Borrower agrees that a final judgment on any such action or proceeding shall be conclusive and may be enforced in other jurisdictions
by suit on the judgment or in any other manner provided by law.
                   (b)         Nothing in this Section 15.12 shall affect any right of Banks to serve legal process in any other manner
permitted by law or affect the right of any Bank to bring any action or proceeding against Borrower or any of its Subsidiaries or their properties in the courts of any other jurisdictions.
                   (c)         To the extent that Borrower has or
hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its
property, Borrower hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the other Loan Papers.
          
SECTION 15.13         Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when Administrative Agent shall have received counterparts hereof signed by all of the
parties hereto or, in the case of any Bank as to which an executed counterpart shall not have been received, Administrative Agent shall have received telegraphic or other written confirmation from such Bank of execution of a counterpart hereof by
such Bank.
          
SECTION 15.14         No Third Party Beneficiaries. It is expressly intended that there shall be no third party
beneficiaries of the covenants, agreements, representations or warranties 
 71

 
 herein contained other than Book Runner and Sole Lead Arranger, and Participants and Purchasers permitted pursuant to Section 15.10
