RECITALS:


A.    The Borrowers, the Lenders signatory thereto and the Administrative Agent signed a Senior Credit Agreement dated as of September 13, 2011, as amended by the First Amendment and Consent to Senior Credit Agreement dated as of September 5, 2012, the Second Amendment and Consent to Senior Credit Agreement dated as of April 10, 2015, and the Third Amendment to Senior Credit Agreement dated as of April 8, 2016 (collectively, the "Existing Credit Agreement").  Under the Existing Credit Agreement, the Lenders severally established in favor of the Borrowers Commitments set forth on the Lenders Schedule annexed as Schedule 2 to the Existing Credit Agreement until the Facility Termination Date, subject to the Maximum Credit Amount and the Borrowing Base. Capitalized terms used in this Fourth Amendment (including the Recitals) but not otherwise defined shall have the meaning given to that term in the Existing Credit Agreement.


B.    The Bank of Nova Scotia, which has been a Lender under the Existing Credit Agreement and the other Loan Documents, will cease being a Lender under the Existing Credit Agreement and the other Loan Documents effective as of the Fourth Amendment Effective Date (the “Fourth Amendment Exiting Lender”), whereupon (in lieu of anything to the contrary in Article 14 of the Credit Agreement) certain of the other Lenders shall acquire a proportionate share of Fourth Amendment Exiting Lender’s Outstanding Credit Exposure and Commitments, as more particularly provided for in this Fourth Amendment.


C.    Unit has: (x) advised Administrative Agent and the Lenders of Unit’s intent to sell fifty percent (50%) of its Equity Interests in Superior and their respective Subsidiaries, before the next Determination Date to occur after the Fourth Amendment Effective Date, on terms that are acceptable to, and have been approved by, Administrative Agent (the “Superior Sale”), subject to the conditions that (i) the Superior Sale results in net sales proceeds inuring to Unit over two hundred million dollars ($200,000,000) (with $200,000,000 being herein referred to as the 








1





“Superior Sale Net Proceeds”), and (ii) Borrowers shall, on the same Business Day of Unit’s receipt of the Superior Sale Net Proceeds, cause the Superior Sale Net Proceeds to be paid to Administrative Agent (for the ratable benefit of the Lenders) to pay down the existing outstanding principal balance of the Outstanding Credit Exposure by the Superior Sale Net Proceeds (the conditions in preceding sub-clauses (i) and (ii) of this clause (x) of this Recital C, are herein, together, called the “Superior Sale Paydown Conditions”); and (y) requested that Administrative Agent and the Required Lenders consent to permit Unit to facilitate and consummate the Superior Sale, subject to (without limitation) the Superior Sale Paydown Conditions, and at closing of the Superior Sale automatically remove and irrevocably release and discharge each Person constituting Superior and their respective Subsidiaries as a Borrower, Subsidiary Guarantor and/or co-obligor under the Existing Credit Agreement and the other Loan Documents, provided that the Superior Sale Paydown Conditions shall have been duly satisfied (the “Superior Release”). Administrative Agent and Required Lenders are agreeable to granting such consents, subject to this Fourth Amendment.


D.    Borrowers have further requested, and the Lenders have agreed, to amend certain provisions of the Existing Credit Agreement and the other Loan Documents, all as set forth herein.


NOW, THEREFORE, in consideration of the mutual covenants and agreements in this Fourth Amendment, and other good and valuable consideration, receipt of which is acknowledged by the parties, the parties agree as follows:


1.    Lenders Schedule.  Schedule 2 annexed to the Existing Credit Agreement is hereby deleted and replaced in its entirety by the applicable revised Schedule 2 annexed to this Fourth Amendment for the applicable period (as more particularly set forth therein).  Each Lender shall have the Commitment set forth opposite that Lender's name on the applicable replacement Schedule 2, for the following periods of time: (i) from the Fourth Amendment Effective Date until the earlier to occur of the next Determination Date or the Superior Release Effective Date (as defined below); and (ii) on and from the Superior Release Effective Date until the next Determination Date to occur thereafter.


2.    Reaffirmation of the Total Commitment and Reduction of Maximum Credit Amount; Subject to Automatic Reductions On the Occurrence of the Superior Release Effective Date.  Borrowers, Lenders, and Administrative Agent hereby agree, stipulate, and confirm that as of the Fourth Amendment Effective Date, and until the earlier to occur of either the next Determination Date or the Superior Release Effective Date: (i) the Total Commitment is reaffirmed at “$475,000,000”; and (ii) the Maximum Credit Amount is reduced from “$875,000,000” to “$475,000,000.” From the Fourth Amendment Effective Date, and until the earlier to occur of the next Determination Date or the Superior Release Effective Date, all references in Section 2.1 of the Existing Credit Agreement and elsewhere in the Existing Credit Agreement or any other Loan Document to a Total Commitment and a Maximum Credit Amount shall, for all purposes, mean and refer to a Total Commitment of "$475,000,000.00" and a Maximum Credit Amount of “$475,000,000.00.”  On the Superior Release Effective Date, and until the next Determination Date to occur thereafter: (x) the Total Commitment shall automatically, and with no further action or documentation being required from or by any Person, be reduced from “475,000,000” to “$425,000,000”; and (y) the Maximum Credit Amount shall automatically, and with no further action or documentation being required from or by any Person, be reduced from “$475,000,000” to “$425,000,000.”  On the Superior Release 












2





Effective Date and until the next Determination Date to occur thereafter, all references in Section 2.1 of the Existing Credit Agreement and elsewhere in the Existing Credit Agreement or any other Loan Document to a Total Commitment and a Maximum Credit Amount shall, for all purposes, automatically mean and refer to a Total Commitment of "$425,000,000.00" and a Maximum Credit Amount of “$425,000,000.00.”


3.    Increase to the Borrowing Base; Subject to Automatic Reduction On the Occurrence of the Superior Release Effective Date.  From the Fourth Amendment Effective Date, and until the earlier to occur of the next Determination Date or the Superior Release Effective Date, the reference in Section 2.6.1 of the Existing Credit Agreement and elsewhere in the Existing Credit Agreement or any other Loan Document to a Borrowing Base of "$475,000,000" is hereby deleted and replaced with "$525,000,000", subject, however, to all applicable terms, conditions and limitations set forth in the Credit Agreement. The parties acknowledge and agree that the redetermination of the Borrowing Base as provided in this Section 3 constitutes the April 1, 2018 scheduled redetermination of the Borrowing Base under the Existing Credit Agreement. Without limitation of the foregoing, on and from the Superior Release Effective Date, and until the next Determination Date to occur thereafter, the Borrowing Base shall automatically, and with no further action or documentation being required from or by any Person, be hereby reduced from “525,000,000” to “$425,000,000.”


4.    Additional Modifications to Existing Credit Agreement.  The Existing Credit Agreement is hereby further amended as follows:


(a)    The Borrowers have advised that Unit intends to facilitate and consummate the Superior Sale, and have requested that Administrative Agent and the Required Lenders consent to the Superior Sale and to the Superior Release. Subject to the Existing Credit Agreement, as amended by this Fourth Amendment, and in consideration thereof, including the Borrowers’ timely satisfaction of the Superior Sale Paydown Conditions, the Administrative Agent and the Required Lenders agree that: (i) Borrowers and Unit may facilitate and consummate the Superior Sale, subject to the Borrowers’ obligation to first timely satisfy the Superior Sale Paydown Conditions (the date on which the Superior Sale is duly consummated is herein called the “Superior Sale Effective Date”); and (ii) on Borrowers’ satisfaction of the Superior Sale Paydown Conditions by timely remitting all Superior Sale Net Proceeds to Administrative Agent (for the ratable benefit of the Lenders) on the Superior Sale Effective Date to paydown the principal balance of the Outstanding Credit Exposure outstanding at such time by such amount (the date on which the Superior Sale Paydown Conditions are duly satisfied is herein called the “Superior Release Effective Date”), the Superior Release shall be deemed to have occurred for all intents and purposes of the Credit Agreement and the other Loan Documents, effective as of such Superior Release Effective Date (if any), whereupon each Person constituting Superior and their respective Subsidiaries shall be deemed to have automatically been removed and released by the Lenders as a Borrower, Subsidiary Guarantor and/or co-obligor under the Credit Agreement and the other Loan Documents and from all of its respective liability and obligations regarding the Obligations accruing thereunder. Without limitation of the foregoing, Borrowers acknowledge and agree that if Borrowers consummate the Superior Sale in any manner contrary to the requirements and conditions in this Fourth Amendment and/or as may otherwise be additionally stipulated by Administrative Agent (including, without limitation, if Borrowers fail to timely and fully satisfy the Superior Sale Paydown Conditions), any such failure shall constitute an automatic and immediate Event of Default under the Credit Agreement and the 














3





other Loan Documents and no additional notice or cure period shall apply to any such failure. On the Superior Release Effective Date the Credit Agreement’s definition of “Borrower(s)” shall, automatically, and with no further action or documentation being required from or by any Person, be amended and restated in its entirety to thereafter have this revised meaning: “Each of Unit, Unit Drilling and  Unit Petroleum together with each existing Material Subsidiary of each of the foregoing Persons, and each of their respective successors and assigns, including any receiver, trustee or debtor-in-possession, is each, individually, herein referred to as a “Borrower”, and, collectively, jointly and severally, as the “Borrowers”.”  


(b)    To further effectuate the Superior Release as more particularly described in Section 4(a) of this Fourth Amendment, the parties further agree, as follows, effective as of the Superior Release Effective Date, respecting each of (i) that certain Pledge Agreement (as defined in the Existing Credit Agreement), (ii) that certain related side letter dated April 8, 2016, signed and delivered by the Administrative Agent to, and counter-signed by, Superior LLC in connection with the Pledge Agreement (the “2016 Pledge Side Letter”), and (iii) those certain UCC financing statements naming Unit, as debtor, and naming Administrative Agent, as secured party, filed with the Office of the Delaware Secretary of State on December 21, 2016, as Initial Filing No. 2016-7930835 (the “2016 UCC”) and on February 27, 2017, as Initial Filing No. 2017-1310660 (the “2017 UCC”, together with the 2016 UCC, the “Superior UCCs”; the Superior UCCs, with the Pledge Agreement, and the 2016 Pledge Side Letter are, collectively, herein called the “Superior LLC Pledge Instruments”): Under the Superior LLC Pledge Instruments, one hundred percent (100%) of the Equity Interests owned and held by Unit in Superior LLC, and all of Unit’s related rights, title and interests in all corresponding distributions, profits and proceeds arising therefrom, were (prior to the Superior Release Effective Date, if any) encumbered by Liens and corresponding negative covenants made in favor of the Administrative Agent (to benefit the Lenders). Effective as of and after the Superior Release Effective Date, the Administrative Agent and the Lenders agree that each instrument comprising the Superior LLC Pledge Instruments is deemed to have been released, terminated, and rendered null, void, and of no further force and effect, whereupon Administrative Agent shall, at Unit’s sole cost, file the release and termination instrument respecting the Superior UCCs (in form and substance acceptable to the Administrative Agent) in the appropriate public records of all applicable jurisdictions, to give effect to the foregoing agreements to terminate and release the Superior LLC Pledge Instruments.


(c)    As of the Fourth Amendment Effective Date, the Existing Credit Agreement is amended to delete the stricken text (indicated textually like this example: stricken text) and to add the underlined text (indicated textually like this example: underlined text) as set forth in the revised, conformed copy thereof attached as Exhibit B hereto, which is incorporated into this Fourth Amendment by this reference. Any Exhibits and Schedules to the Existing Credit Agreement not being amended and restated by this Fourth Amendment (whether by attaching same as stand-alone new exhibits or schedules to this Fourth Amendment, or by including same within the revised, conformed copy of the Loan Agreement attached as Exhibit B hereto), shall remain unmodified and of full force and effect as set forth in the Existing Credit Agreement.


5.    Post-Closing Obligations.  


A. The Credit Parties shall have sixty (60) days following the Fourth Amendment Effective Date to sign and deliver the Oil and Gas Mortgages required under Section 6.11(a)(i) of the Credit Agreement (the 60 days may be extended by Administrative Agent in its sole 












4





discretion), respecting the Oil and Gas Properties more particularly described on Exhibit A attached hereto and incorporated herein by this reference. Borrowers’ failure to timely deliver those Mortgages within the time provided shall constitute an immediate Event of Default under the Credit Agreement and no additional notice or cure period shall apply to that failure.


B. The Credit Parties shall have thirty (30) days following the Fourth Amendment Effective Date (which 30-days may be extended by Administrative Agent in its sole discretion) to sign and deliver to the Administrative Agent a pledge agreement (in form and substance substantially similar to the Pledge Agreement (as defined in the Existing Credit Agreement), and acceptable to Administrative Agent), pursuant to which the Credit Parties shall grant and pledge in favor of Administrative Agent (for the ratable benefit of the Lenders) first priority liens and security interests encumbering (i) all of each Credit Party’s respective Equity Interests held at such time in Superior LLC (which shall not be less than fifty percent (50%) of the aggregate Equity Interests held at such time in Superior LLC by all Persons holding any such Equity Interests), together with (ii) all of each Credit Party’s related rights, title and interests in and to all corresponding distributions, profits and proceeds arising therefrom. Contemporaneously with the Credit Parties’ delivery of such a pledge agreement to the Administrative Agent, the Administrative Agent shall cause a new UCC financing statement to be filed against each such grantor thereunder (in each jurisdiction as may deemed necessary by Administrative Agent), which shall include a description of the collateral as more particularly provided for in said pledge agreement. The Credit Parties’ failure to timely deliver such a pledge agreement within the time provided for herein shall constitute an immediate Event of Default under the Credit Agreement and no additional notice or cure period shall apply to that failure.  


6.    Ratification of Representations, Warranties, Covenants and Other Provisions.  The remaining terms, provisions and conditions in the Existing Credit Agreement and the other Loan Documents not modified hereby shall continue and remain in full force and effect, and are incorporated herein and ratified and adopted herein by this reference (including without limitation, the consents, waivers and other provisions of Article 17 thereof), with the same force and effect as if reiterated at length herein. The Borrowers hereby restate, confirm, and ratify the covenants in the Existing Credit Agreement and the other Loan Documents (after giving effect to this Fourth Amendment). The Borrowers represent and warrant to the Administrative Agent and the Lenders as of the Fourth Amendment Effective Date that the representations and warranties in the Existing Credit Agreement and the other Loan Documents (after giving effect to this Fourth Amendment) are true and correct in all material respects as of the Fourth Amendment Effective Date (except to the extent a representation or warranty is stated to relate solely to an earlier date, in which case such representations and warranties will have been true and correct on and as of such earlier date). The Borrowers further represent and warrant to the Administrative Agent and the Lenders as of the Fourth Amendment Effective Date (after giving effect to this Fourth Amendment) that: (i) no Default or Event of Default exists under the Existing Credit Agreement, as amended by this Fourth Amendment, or any other Loan Document; (ii) Borrowers have all necessary power and authority to sign, deliver and perform their respective obligations under the Existing Credit Agreement, as amended by this Fourth Amendment, and the other Loan Documents; (iii) the signing, delivery, and performance by the Borrowers of this Fourth Amendment has been duly authorized by all necessary action on their part; (iv) the Existing Credit Agreement, as amended by this Fourth Amendment, and the other Loan Documents has each been duly signed and delivered by the Borrowers and each Loan Document constitutes the legal, valid, and binding obligation of the Borrowers enforceable under its terms, except if the 










5





enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, or other similar laws generally affecting the enforcement of creditor’s rights and general principles of equity; (v) the signing and delivery of the Existing Credit Agreement, as amended by this Fourth Amendment, or any other Loan Document by the Borrowers and their performance of their respective obligations hereunder and thereunder require no authorizations, approvals, or consent, or registration or filing with, or further action by, any Governmental Authority, except for those that have been obtained or made and are in effect; and (vi) neither the signing and delivery of the Existing Credit Agreement, as amended by this Fourth Amendment, or any other Loan Document, nor compliance with the terms hereof or thereof, will contravene, or result in a breach of, the charter, by-laws, operating agreement, or other constituent corporate governance documents of the Borrowers, any requirement of applicable law, any agreement or instrument to which the Borrowers are a party or by which it is bound or to which it or its Property or assets are subject, or constitute a default under any such agreement or instrument.

6

9.    Effect on Credit Documents.  Except only as amended in this Fourth Amendment, the Existing Credit Agreement and all other Loan Documents remain in full force and effect as heretofore signed and are hereby ratified, confirmed, and continued for all purposes. Nothing in this Fourth Amendment shall waive any of the Administrative Agent's or any Lender's rights under the Loan Documents (after giving effect to this Fourth Amendment), including the waiver of any Default or Event of Default, however denominated.

ARTICLE 2
THE CREDITS


2.1    Commitments; Initial Total Commitment; Maximum Credit Amount.  From and including the Fourth Amendment Effective Date and up to the Facility Termination Date, each Lender severally agrees, on the terms and conditions of this Agreement, to (i) make Loans to the Borrowers and (ii) participate in LCs issued on the request of the Borrowers, provided that, after giving effect to the making of each such Loan and the issuance of each such LC, the Lender’s Outstanding Credit Exposure does not exceed its Commitment and the Total Outstanding Credit Exposure does not exceed the Total Commitment.  Subject to the terms of this Agreement, Unit, as the designated borrowing agent on behalf of all of the Borrowers, may borrow, repay and re-borrow at any time before the Facility Termination Date. Each Lender’s Commitment will expire on the Facility Termination Date.  The LC Issuer will issue LCs on the terms and conditions set forth in Section 2.19. As of the Fourth Amendment Effective Date, and until the earlier to occur of either the next Determination Date or the occurrence of the Superior Release Effective Date (if any) in accordance with the Fourth Amendment: (a) the Total Commitment is $475,000,000; and (b) the Maximum Credit Amount is also $475,000,000. Without limitation of any of the foregoing, from and after the occurrence of the Superior Release Effective Date, if any, in accordance with the Fourth Amendment, and until the next Determination Date to occur thereafter: (x) the Total Commitment shall automatically, and without any further action or documentation being required from or by any Person, be hereby reduced to $425,000,000; and 












24





(y) the Maximum Credit Amount shall automatically, and without any further action or documentation being required from or by any Person, be hereby reduced to $425,000,000.  Any increases in the Total Commitment will be subject to and in accordance with Section 14.6 and any increase in the Maximum Credit Amount requires the written consent of all Lenders.


2.2    Minimum Amount of Each Advance.   Each Eurodollar Advance will be in the minimum amount of $2,000,000 (and in additional multiples of $1,000,000), and each Floating Rate Advance will be in the minimum amount of $200,000 (and in additional multiples of $100,000), provided, that any Floating Rate Advance may be in the amount of the Available Total Commitment.  


2.3    Ratable Loan.  The Lenders will make each Advance according to their Pro Rata Shares.


2.4    Types of Advances.  The Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof.  Unit will select advances on behalf of the Borrowers in accordance with Sections 2.9 and 2.10.


2.5    Facility Fee; Commitment Fee; Late Fees; Agency and Other Fees.


2.5.1.    Facility Fee.  Borrowers will pay to the Administrative Agent for the benefit of the Lenders a fully earned and non-refundable upfront facility fee calculated by the respective invited/solicited commitment levels tendered to each Lender, as provided in Addendum I to the separate Summary of Terms and Conditions dated as of July 7, 2011 agreed to by the Administrative Agent.  Any increases in the Total Commitment above the amounts designated in Section 2.1 will be contingent on the Borrowers’ payment of an applicable market rate facility fee on the amount of the increase(s) to Administrative Agent for the benefit of the Lenders increasing its or their Commitments or on the Commitment of any Additional Lender(s) under Section 14.6.


2.5.2.    Commitment Fee.  The Borrowers shall pay the Administrative Agent for the Pro Rata Share of each Lender a commitment fee equal to the per annum Commitment Fee Rate (as set forth on the Pricing Schedule) times the average daily amount of the Available Total Commitment from the date of this Agreement through the Facility Termination Date.  Accrued commitment fees are payable in arrears within 10 days of Unit’s receipt of the quarterly invoice from the Administrative Agent following the close of each calendar quarter and on the Facility Termination Date.  All accrued commitment fees are payable on the effective date of any termination of the Commitments of the Lenders to make Credit Extensions. 


2.5.3.    Late Fees.  To the extent any payment due under a Loan Document is not paid within ten (10) calendar days of its scheduled due date, then, in addition to any interest (accrued at the contract rate of the Notes and prior to imposition of the default rate pursuant to Section 2.12) or other fees and charges due, Borrowers will pay to the Administrative Agent for the allocable benefit of the Lenders a late fee equal to five percent (5.0%) of the amount of the payment that was required to have been made.












25





2.5.4.    Agency and Other Fees.  Borrowers will pay agency and other fees to the Administrative Agent in the amounts and on the terms agreed to in writing between the Administrative Agent and the Borrowers.    


2.6    Borrowing Base.  


2.6.1.  Subject to the terms, provisions, and limitations of this Agreement, as of the Fourth Amendment Effective Date, and until the earlier to occur of either the next Determination Date or the occurrence of the Superior Release Effective Date (if any) in accordance with the Fourth Amendment, the Borrowing Base is $525,000,000.00, subject, however, to all applicable terms, conditions and limitations as set forth in this Agreement. Without limitation of any of the foregoing, from and after the occurrence of the Superior Release Effective Date, if any, in accordance with the Fourth Amendment, and until the next Determination Date to occur thereafter, the Borrowing Base shall automatically, and without any further action or documentation being required from or by any Person, be hereby reduced to $425,000,000.  The Borrowing Base is based on (i) the loan value which the Lenders assign to the various Credit Parties’ Oil and Gas Properties being evaluated, (ii) until such time as the Superior Release Effective Date (if any) shall have occurred in accordance with the Fourth Amendment, the loan value which the Lenders assign to Superior Cash Flow, and (iii) any other credit factors (including without limitation the assets, liabilities, cash flow, hedged and unhedged exposure to price, foreign exchange rate, and interest rate changes, business, properties, prospects, management and ownership of Credit Parties) as the Lenders deem significant. The Lenders and the Administrative Agent have no obligation to agree on or designate the Borrowing Base at any particular amount, whether in relation to the Total Commitment or otherwise.


2.6.2.  On March 1 and September 1 of each year, beginning September 1, 2018 (it being stipulated Unit has timely furnished such information for March 1, 2018), Unit will furnish to each Lender the information Administrative Agent has then requested concerning the Credit Parties’ businesses and properties (including the information specified in Sections 6.1(vii), (viii) and (ix)).


2.6.3.  Starting no later than October 1, 2018 and no later than each following April 1st and October 1st, the Borrowing Base will be determined in accordance with the following procedure:


(a)The Administrative Agent will submit in writing to the Lenders its proposed Borrowing Base amount;


(b)  Each Lender will have ten (10) Business Days to notify the Administrative Agent in writing if it agrees or disagrees with the proposed amount; provided, however, no increase in the Borrowing Base will become effective unless approved in writing by all Lenders.  If, within the time set out in the preceding sentence,






















26







(1)All Lenders agree, then the new Borrowing Base will be the amount proposed by the Administrative Agent (which shall be deemed to include any Lender that has not timely notified Administrative Agent in writing of its approval or disapproval, such silence being deemed to be an approval of the proposed Borrowing Base amount by the silent (non responding) Lender); or


(2)(i) Not all Lenders agree with the proposal of the Administrative Agent, or (ii) if the Total Commitment has been terminated or has expired and the Required Lenders have not affirmatively approved the Administrative Agent’s proposal with respect to a decrease in, or maintenance of, the Borrowing Base, then the Administrative Agent and the Required Lenders will, within five (5) Business Days, diligently attempt in good faith to agree on a Borrowing Base amount. If agreement is reached then the amount determined by the Administrative Agent and the Required Lenders will be the Borrowing Base amount; or


(3)The Administrative Agent and the Required Lenders cannot agree on the amount of the Borrowing Base within the five (5) Business Day period, then the proposed Borrowing Base will be the amount calculated by the Administrative Agent as the “weighted arithmetic average” of the Borrowing Base as determined by each individual Lender and communicated to the Administrative Agent in writing.  For purposes of this paragraph, the “weighted arithmetic average” of the Borrowing Base will be determined by first multiplying the Borrowing Base proposed in writing to the Administrative Agent by each Lender’s Pro Rata Share, and then adding the results of each calculation, with the Borrowing Base then being the lesser of (i) the resulting weighted arithmetic average amount, or (ii) the amount of the Borrowing Base as last determined under this Agreement. 


(c)The Administrative Agent will then promptly notify Unit in writing of the new Borrowing Base amount.  The amount of the Borrowing Base subject to the Administrative Agent’s notice will be effective as of the date the notice is sent to Unit (a “Determination Date“) unless, within five (5) Business Days following receipt of the Administrative Agent’s notice, Unit designates in writing a lesser amount in which case the lesser amount designated by Unit will be the Borrowing Base amount effective when the Administrative Agent receives Unit’s written designation.  


2.6.4.  If Unit does not timely furnish all the information requested by the Administrative Agent in subsection 2.6.2, Administrative Agent may designate the Borrowing Base at any amount the Lenders or the Required Lenders, as applicable, reasonably determine (and may redetermine the Borrowing Base from time to time) until each Lender receives all the requested information. Once the Lenders have received all the requested information, Lenders or the Required Lenders, as applicable, in their 
















27







discretion, will designate a new Borrowing Base under the procedures in subsection 2.6.3.


2.6.5.  In addition to Scheduled Redeterminations, the Required Lenders are permitted to make a Special Redetermination of the Borrowing Base once between each Determination Date by notifying the Administrative Agent and Borrowers. Any Special Redetermination by the Required Lenders shall be in addition to any reduction of the Borrowing Base by the Required Lenders under Section 7.4(iv).


2.6.6.  In addition to Scheduled Redeterminations, any other Special Redeterminations pursuant to Section 2.6 and the voluntary Commitment reduction pursuant to Section 2.8.3, Unit may request a Special Redetermination of the Borrowing Base once between each Scheduled Redetermination.  In addition, Unit may request Special Determinations from time to time as significant developments, exploration or Acquisition opportunities are presented to Borrowers.  Borrower shall deliver written notice of such Special Redetermination request to the Administrative Agent which shall include (i) a reserve report or engineering report prepared as of a date not more than 30 days prior to such request, and (ii) the amount of the Borrowing Base requested by Unit and the date on which Unit requests such redetermined Borrowing Base to be effective.  Upon receipt of the reserve report or engineering report, the Administrative Agent shall, subject to approval of the Required Lenders, or all Lenders in the event of a proposed increase in the Borrowing Base, redetermine the Borrowing Base in accordance with the calculation procedures of Section 2.6.3(a), (b) and (c), provided that the Administrative Agent and the Lenders shall have thirty (30) days from Administrative Agent's receipt of the information requested of Unit under clauses (i) and (ii) above to agree with the Lenders on the redetermined amount of the Borrowing Base and so notify Unit in writing.


2.6.7.  If at any time, the Total Outstanding Credit Exposure exceeds the lesser of (i) the Borrowing Base, or (ii) the Total Commitment (a “Deficiency”) because of a reduction in the Borrowing Base resulting from a redetermination in accordance with this Section 2.6 (excluding Section 2.6.8), Administrative Agent will notify Unit in writing of the Deficiency and within ten (10) days from the date of that deficiency notice, Unit will elect one of the following options:  


(a)  To prepay the Loans in an amount equal to or more than the Deficiency; 


(b)  Dedicate to this Agreement (including the negative pledge provision of Section 7.12) other Oil and Gas Properties or assets acceptable to the Administrative Agent and the Required Lenders that are not then included in the Borrowing Base that are of a value, as determined by the Administrative Agent and the Required Lenders, such that the Outstanding Credit Exposure does not exceed the Borrowing Base (as adjusted to include the values of the additional Oil and Gas Properties and/or midstream assets); or




















28





(c)  Start monthly principal payments each equal to the amount of the Deficiency divided by the number of whole calendar months between the date of the Deficiency notice and the next Scheduled Redetermination.


If Unit elects to (i) prepay the Loans under clause (a) or (ii) commence monthly principal payments under clause (c), the prepayment or first monthly payment, as applicable, will be due within twenty (20) days after the date of Unit’s timely election.  The prepayment or monthly principal payments will be applied in reduction of the principal balance of the Loans.  If Unit elects to commit Oil and Gas Properties under clause (b) above, the Borrowers will provide the Administrative Agent with descriptions of the Oil and Gas Properties or other approved assets (together with any applicable current valuations and engineering reports which may be requested by the Administrative Agent).
2.6.8.  The Borrowing Base will be automatically reduced if and to the extent a Borrower issues or incurs Indebtedness (other than any Obligations) as follows: (i) a dollar ($1.00) for dollar ($1.00) reduction if the Indebtedness is on a pari passu basis in right of payment with the Obligations or (ii) an amount equal to a twenty five cents ($0.25) reduction for each one dollar ($1.00) amount of Indebtedness incurred after the effective date of this Agreement that is expressly subordinated in right of payment to the Obligations (including subordinated Indebtedness convertible to equity in Unit) so long as such Indebtedness is in compliance with the limitations of Section 7.2(ix).


2.6.9.  Unit may, from time to time upon ten (10) days prior written notice to the Administrative Agent, reduce the Borrowing Base by designating a Borrowing Base which is lower than the Borrowing Base then in effect.  Any such designation by Unit shall be effective on the tenth (10th) day following the date of the Administrative Agent's receipt of such written notice.


2.7    Repayment of Loans; Evidence of Loans.


2.7.1.  Borrowers hereby unconditionally and jointly and severally promise to pay to the Administrative Agent, for the account of each Lender, on the Facility Termination Date, the then unpaid principal amount of all Loans made to them.

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


2.7.3.  The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the type and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from Borrowers to each Lender hereunder and (iii) the amount of any sum 
















29





received by the Administrative Agent hereunder for the account of the Lenders and each Lender's Pro-Rata Share thereof.


2.7.4.  The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Credit Parties to repay the Loans in accordance with the terms of this Agreement.


2.7.5.  Any Lender may request that Loans made by it be evidenced by a promissory note.  In such event, the Borrowers shall prepare, jointly execute and deliver to the order of such Lender one or more promissory notes payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent.  Thereafter, the Loans evidenced by such promissory note(s) and interest thereon shall at all times (including after assignment pursuant to Section 14.3) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if a promissory note is a registered note, to such payee and its registered assigns).


2.8    Principal Payments; Termination and Reduction of Commitment.


2.8.1.  Optional Principal Payments.  The Borrowers may at any time and from time to time, without penalty or premium, on prior notice to the Administrative Agent pay (i) all outstanding Floating Rate Advances, or (ii) a part of the outstanding Floating Rate Advance in a minimum amount of $200,000 (and any additional multiples of $100,000).  The Borrowers may from time to time, without premium or penalty (but subject to the payment of any funding indemnification amounts required by Section 3.5 including applicable breakage fees due hereunder), on three (3) Business Days’ prior written notice to the Administrative Agent, pay all (i) outstanding Eurodollar Advances, or, (ii) a part of the outstanding Eurodollar Advances in a minimum total amount of $2,000,000 (and any additional integral multiples of $1,000,000). 


2.8.2.  Mandatory Principal Payments.  In addition to the mandatory principal payments required due to a Deficiency in accordance with Section 2.6.7, if at any time a Deficiency occurs as a result of the a reduction of the Borrowing Base under Section 2.6.8 or 7.4, Borrowers will, within three (3) Business Days following written notice from Administrative Agent promptly prepay the principal of the Loans with proceeds of such Indebtedness issuance or asset sale in an amount at least equal to the Deficiency (or, if the Loans have been paid in full, deposit with the Administrative Agent the amount required to eliminate the Deficiency, which amount shall be applied by the Administrative Agent to the payment of Reimbursement Obligations with respect to any LCs as they become due and payable; any balance remaining after (i) all LCs have expired or been fully drawn on or (ii) after the Deficiency no longer exists will be returned to Unit) together with interest during the period of the Deficiency.  Any principal or interest prepaid under this subsection will be in addition to, and not in lieu of, all payments otherwise then required under the Loan Documents.
















30





2.8.3.  Termination and Reduction of Commitments.  


(a)    Unless previously terminated, the Commitments shall terminate on the Facility Termination Date.


(b)    The Borrowers may once between each Scheduled Redetermination reduce the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $5,000,000 and not less than $25,000,000 (or, if less, the remaining amount of the Commitments), and (ii) the Borrowers shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.6.7 or 2.8.2, the Total Outstanding Credit Exposure would exceed the Borrowing Base. 


(c)    The Borrowers shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section 2.8.3 at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof.  Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof.  Each notice delivered by the Borrowers pursuant to this paragraph (c) shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrowers may state that such notice is conditioned upon the effectiveness of other credit facilities or refinancing, in which case such notice may be revoked by the Borrowers (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.  Any termination or reduction of the Commitments shall be permanent, provided that the Commitments may be increased in accordance with Section 14.6.  Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.


2.9    Method of Selecting Loan Types and Interest Periods for New Advances.  Unit will select each type of Advance and, in the case of a Eurodollar Advance, the applicable Interest Period.  Unit will give the Administrative Agent irrevocable notice (a “Borrowing Notice“) not later than 11:00 a.m. (Tulsa time) on the same Business Day as the Borrowing Date of each Floating Rate Advance and three Business Days before the Borrowing Date for each Eurodollar Advance.  Unit’s notice will specify:


		
	(i)
	the Borrowing Date, which must be a Business Day, of the Advance;




		
	(ii)
	the total amount of the Advance;




		
	(iii)
	the type (Floating Rate or Eurodollar) of Advance selected; and




		
	(iv)
	in the case of a Eurodollar Advance, the applicable Interest Period.




Not later than 1:00 p.m. (Tulsa time) on each Borrowing Date, each Lender will make available its Loan or Loans in funds immediately available in Tulsa to the Administrative Agent at its address specified under Article 15.  The Administrative Agent will make the funds received from the Lenders immediately available to the Borrowers at the Administrative Agent’s address.








31





2.10    Conversion and Continuation of Outstanding Advances.  Each Floating Rate Advance will continue as Floating Rate Advance unless converted into Eurodollar Advance under this Section 2.10 or is repaid.  Each Eurodollar Advance will continue as a Eurodollar Advance until the end of its applicable Interest Period, at which time the Eurodollar Advance will be automatically converted into a Floating Rate Advance unless (x) the Eurodollar Advance is or was repaid or (y) Unit gives the Administrative Agent a Conversion/Continuation Notice requesting that, at the end of the Interest Period, the Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period.  Subject to the terms of Section 2.2, Unit may elect from time to time to convert all or any part of a Floating Rate Advance into a Eurodollar Advance.  Unit will give the Administrative Agent irrevocable notice (a “Conversion/Continuation Notice“) of each conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance.  A Conversion/Continuation Notice must be given by 11:00 a.m. (Tulsa time) on a day that is at least three Business Days before the date of the requested conversion or continuation and specify:


		
	(i)
	the requested date, which must be a Business Day, of the conversion or continuation;




		
	(ii)
	the total amount of and the type of the Advance (Floating Rate Advance or Eurodollar Advance) that is to be converted or continued; and




		
	(iii)
	the duration of the applicable Interest Period.




2.11    Interest Rate.  Each Advance will bear interest at a variable per annum rate equal to the Eurodollar Rate or the Floating Rate as applicable, except as otherwise provided in Section 2.12.  Each Floating Rate Advance will bear interest on its outstanding principal amount, for each day from and including the date the Advance is made or is automatically converted from a Eurodollar Advance into a Floating Rate Advance under Section 2.10 (but excluding the date it is paid or is converted into a Eurodollar Advance under Section 2.10) at an annual rate equal to the Floating Rate for that day.  Changes in the rate of interest on that part of any Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in the Alternate Base Rate.  Each Eurodollar Advance will bear interest on its outstanding principal amount from and including the first day of the Interest Period applicable to it until (but not including) the last day of that Interest Period.  The Administrative Agent will determine the applicable interest rate for each Eurodollar Advance based on Unit’s selections under Sections 2.9 and 2.10 and otherwise in accordance with the terms of this Agreement.  No Interest Period may end after the Facility Termination Date.


2.12    Effect of Default or Deficiency on Advances/Rates Applicable After Default or Deficiency. Despite Section 2.9, 2.10, or 2.11, during a Default or Deficiency the Required Lenders may, at their option by written notice to Unit, declare that no Advance will be made as, converted into, or continued as a Eurodollar Advance and no LCs will be issued.  During the continuance of an Event of Default, each Eurodollar Advance and each Floating Rate Advance will bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to the Interest Period plus an additional two hundred basis points (2.0%) per annum, and the LC Fee will be increased by an additional two hundred basis points (2.00%) per annum.  During a Default that remains uncured (prior to an Event of Default) or a Deficiency, interest 
















32





will be determined at the applicable Level IV Status Floating Rate per annum plus an additional fifty basis points (0.50%) as to Floating Rate Advances or applicable Level IV Status Eurodollar Rate plus an additional two hundred basis points (2.00%) as to Eurodollar Rate Loans per annum as to Eurodollar Rate. During a Default or Event of Default under Subsections 10.1.6 or 10.1.7, the interest rates set forth above and the increase in the LC Fee will apply to all Credit Extensions without any election, notice or other action on the part of the Administrative Agent or any Lender; provided, however, the default interest rate specified above shall not accrue at the same time a late fee is being assessed pursuant to Section 2.5.3, such election to be at the option of the Administrative Agent and the Required Lenders.


2.13    Method of Payment of Obligations.  All Obligation payments will be made, without setoff, deduction, or counterclaim, in immediately available funds to the Administrative Agent at the Administrative Agent’s address specified by Section 15.1, by 12:00 noon (Tulsa time) on the date when due (other than payments of Rate Management Obligations owed to Lender Counterparties, which shall be made in accordance with the applicable Financial Contracts governing such Rate Management Obligations) and will (except in the case of Reimbursement Obligations for which the LC Issuer has not been fully indemnified by the Lenders, or as otherwise required under this Agreement) be applied ratably by the Administrative Agent among the Lenders.  The Administrative Agent will promptly pay in the same type of funds that the Administrative Agent received to each Lender at the Lender’s address specified in Section 15.1 (or at the address specified in a notice received by the Administrative Agent from the Lender)any payments the Administrative Agent receives on behalf of the Lender.  The Administrative Agent may charge Borrowers’ accounts (other than any Excluded Account) at BOk for each payment of principal, interest, Reimbursement Obligations and fees due under this Agreement.  Each reference to the Administrative Agent in this Section 2.13 will also be deemed to refer, and will apply equally, to the LC Issuer, in the case of payments required to be made by the Borrowers to the LC Issuer under Section 2.19.6.


Subject to the provisions of Section 11.4, all principal or interest payments on any Note or Loan will be applied first to any interest then due and payable, then to principal, and last to any prepayment of principal and interest in compliance with Section 2.8.  All distributions of amounts described above will be made by Administrative Agent pro rata to each Lender then owed Obligations described in this section in proportion to all amounts owed to Administrative Agent and all Lenders which are described in this Section 2.13; provided that if any Lender then owes payments to LC Issuer for the purchase of a participation under Section 2.19.2 or to Administrative Agent under Section 13.7, any amounts otherwise distributable under this section to the Lender will be deemed to belong to LC Issuer, or Administrative Agent, respectively, to the extent of the unpaid payments, and Administrative Agent will apply those amounts to pay such unpaid payments rather than distribute those amounts to the Lender.


2.14    Payment of Fees.  All fees paid under this Agreement will be paid in US Dollars on the dates due, in immediately available funds to the Administrative Agent (or the LC Issuer, in the case of fees payable to it).  Fees paid will not be refundable under any circumstances except in the case of inadvertent but conclusive overpayment by Borrowers.
2.15    Telephonic Notices.  The Lenders and the Administrative Agent may extend, convert, or continue Advances, effect selections of types of Advances, and transfer funds based 












33





on telephonic notices made by any person or persons the Administrative Agent or any Lender in good faith believes authorized to act on behalf of the Borrowers.  Borrowing Notices and Conversion/Continuation Notices may be given telephonically.  Unit will deliver promptly to the Administrative Agent a written confirmation executed by an Authorized Officer of each telephonic notice.  If the written confirmation differs in any material respect from the action taken by the Administrative Agent and any Lenders, the records of the Administrative Agent and the Lenders will govern absent manifest error.


2.16    Payment Date.  Interest accrued on each Floating Rate Advance will be payable on the last day of each month, on any date on which the Floating Rate Advance is prepaid (whether due to acceleration or otherwise), and on the Facility Termination Date.  Interest accrued on the principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other than the last day of a month will be payable on the date of conversion.  Interest accrued on each one month (30 day), two months (60 days), or three months (90 days) Interest Period for a Eurodollar Advance will be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid (whether by acceleration or otherwise), and on the Facility Termination Date.  Interest accrued on each Eurodollar Advance having an Interest Period longer than three months (i.e., six months (180 days) Interest Period) will also be payable on the last day of each three-month interval during the Interest Period.  Interest will be payable from the day an Advance is made but not for the day of payment if the payment is received before 12:00 noon (local time) at the place of payment.  If any payment of principal of or interest on an Advance is due on a day which is not a Business Day, that payment will be made on the next succeeding Business Day and, in the case of a principal payment, the extension of time will be included in computing interest on the payment.


2.17    Notification of Advances, Interest Rates, and LC Requests.  The Administrative Agent will promptly notify each Lender of the contents of each Borrowing Notice, Conversion/Continuation Notice, or repayment notice it receives as well as changes in the applicable per annum rate of interest pursuant to the Pricing Schedule. Promptly after notice from the LC Issuer, the Administrative Agent will notify each Lender of the contents of each request for issuance of an LC. 


2.18    Non-Receipt of Funds by the Administrative Agent.  Unless Unit or a Lender, as the case may be, notifies the Administrative Agent before the date on which it is to make a payment to the Administrative Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrowers, a payment of principal, interest or fees, that it does not intend to make the payment, the Administrative Agent may assume that the payment has been made.  The Administrative Agent may, but will not be obligated to, make the amount of the payment available to the intended recipient in reliance on that assumption.  If the Lender or the Borrowers, as the case may be, did not make the payment, the recipient of the payment will when requested by the Administrative Agent, repay the amount of the payment with interest to Administrative Agent.  Interest will apply for each day starting the day the payment was made until the day the Administrative Agent receives the repayment.  Interest will be calculated at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for the day for the first three days and then the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrowers, the interest rate applicable to the relevant Loan.


















34





2.19    Letters of Credit.


2.19.1.    Issuance.  When requested by Unit, the LC Issuer will issue standby Letters of Credit (each, a “LC“) and renew, extend, increase, decrease or otherwise modify each LC (“Modify,” and each action a “Modification“), from time to time before the Facility Termination Date; but only if immediately after each LC is issued or Modified, (i) the total amount of the outstanding LC Obligations does not exceed the LC Sublimit and (ii) the Total Outstanding Credit Exposure does not exceed the Total Commitment. No LC will have an expiration date more than one year from its date of issuance (or, in the case of a Modification, one year after the Modification).  If an expiration date for any LC is within five (5) Business Days before the Facility Termination Date, Borrowers will deposit with the Administrative Agent on the Facility Termination Date immediately available funds in an amount equal to the undrawn amount of the LC.  The Administrative Agent may apply such funds to the payment of Reimbursement Obligations with respect to the LC as they become due and payable, and any balance remaining after such LC has expired or been fully drawn upon will be returned to the Borrowers.


2.19.2.    Participations.  On the issuance or Modification of an LC, the LC Issuer will be deemed, without further action by any party, to have unconditionally and irrevocably sold to each Lender, and each Lender will be deemed, without further action by any party, to have unconditionally and irrevocably purchased from the LC Issuer, a participation in the LC (and each Modification of the LC) and the related LC Obligations in proportion to its Pro Rata Share.


2.19.3.    Notice.  Unit will give the LC Issuer notice before 11:00 a.m. (Tulsa time) at least one Business Day before the proposed date of issuance or Modification of an LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiration date of the LC.  The issuance or Modification of an LC by the LC Issuer is subject to the LC Issuer’s approval and the Borrowers signing and delivering an LC Application or other instruments and agreements relating to the LC as the LC Issuer may reasonably request (each, a “LC Application“).  In the event of a conflict between the terms of this Agreement and the terms of an LC Application, the terms of this Agreement will control.


2.19.4.    LC Fees.  The Borrowers will pay to the Administrative Agent, for the account of the Lenders in accordance with their respective Pro Rata Shares, a per annum letter of credit fee when an LC is issued.  The amount of the fee will be equal to the greater of $500.00 or a per annum rate equal to the Applicable Margin for Eurodollar Loans on the stated amount of the LC (each fee described in this sentence an “LC Fee“).  The Borrowers will also pay to the LC Issuer for its own account at the time of issuance of an LC, a fronting fee in an amount equal to 0.125% of the initial stated amount, and any documentary and processing charges incurred in connection with the issuance or Modification of and draws under LCs in accordance with the LC Issuer’s then standard schedule for those charges.




















35





2.19.5.    Administration; Reimbursement by Lenders.  If the LC Issuer receives demand for payment by a beneficiary under an LC, the LC Issuer will notify the Administrative Agent. The Administrative Agent will then promptly notify the Borrowers and each other Lender of the amount demanded to be paid and the proposed payment date (the “LC Payment Date“).  The responsibility of the LC Issuer to the Borrowers and each Lender will be only to determine that the documents (including each demand for payment) delivered under each LC in connection with the presentment conforms in all material respects with the LC.  In the absence of gross negligence or willful misconduct by the LC Issuer, each Lender will be unconditionally and irrevocably liable without regard to the occurrence of any Default, Event of Default or any condition precedent, to reimburse the LC Issuer on request for (i) the Lender’s Pro Rata Share of the amount of each payment made by the LC Issuer under an LC to the extent the amount is not reimbursed by the Borrowers under Section 2.19.6, plus (ii) interest on the amount to be reimbursed by the Lender for each day from the date of the LC Issuer’s demand for the reimbursement (or, if the demand is made after 12:00 noon (Tulsa time) on that date, from the next succeeding Business Day) to the date paid. The interest to be paid will be calculated at a rate of interest per year equal to the Federal Funds Effective Rate for the first three days and then at a rate of interest equal to the rate applicable to Floating Rate Advances.


2.19.6.    Reimbursement by Borrowers.  The Borrowers are irrevocably and unconditionally obligated to reimburse the LC Issuer on or before the applicable LC Payment Date for any amounts to be paid by the LC Issuer under subsection 2.19.5.  The Borrowers’ reimbursement obligation will be without presentment, demand, protest or other formalities of any kind but either the Borrowers or any Lender may assert any claim for direct (but not consequential) damages suffered by the Borrowers or the Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any LC issued by it complied with the terms of the LC or (ii) the LC Issuer’s failure to pay under any LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of the LC. All amounts paid by the LC Issuer and remaining unreimbursed by the Borrowers will bear interest, payable on demand, for each day until paid at a rate per year equal to (x) the rate applicable to Floating Rate Advances for that day if that day falls on or before the applicable LC Payment Date and (y) the sum of two hundred basis points (2.0%) plus the rate applicable to Floating Rate Advances for that day if that day falls after the LC Payment Date.  The LC Issuer will pay to each Lender in accordance with its Pro Rata Share all amounts received by it from the Borrowers as payment, in whole or in part, for Reimbursement Obligations in regard to any LC issued by the LC Issuer, but only if the Lender has paid the LC Issuer for the LC under Section 2.19.5.  Subject to the terms and conditions of this Agreement, the Borrowers may request an Advance to satisfy any Reimbursement Obligation. 


2.19.7.    Obligations Absolute.  The Borrowers’ obligations under this Section 2.19 are absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim, or defense to payment that the Borrowers may have or have had against the LC Issuer, any Lender, or any beneficiary of a LC.  Borrowers acknowledge and agree that the LC Issuer and the Lenders will not be responsible for, and the 
















36





Borrowers’ Reimbursement Obligation in respect of any LC will not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if those documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrowers, any of their Affiliates, the beneficiary of any LC, any financing institution, or other party to whom any LC may be transferred or any claims or defenses whatsoever of the Borrowers or of any of their Affiliates against the beneficiary of any LC or any transferee. The LC Issuer will not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any LC.  The Borrowers agree that any action taken or omitted by the LC Issuer or any Lender under or in connection with each LC and the related drafts and documents, if done without gross negligence or willful misconduct, will be binding on the Borrowers and will not put the LC Issuer or any Lender under any liability to the Borrowers.  Nothing in this subsection 2.19.7 will limit the right of the Borrowers to make a claim for damages as provided in subsection 2.19.6.


2.19.8.    Actions of LC Issuer.  The LC Issuer is entitled to rely, and will be fully protected in, relying on any LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and on advice and statements of legal counsel, independent accountants, and other experts selected by the LC Issuer.  The LC Issuer will be fully justified in failing or refusing to take any action under this Agreement unless it will first have received the advice or concurrence of the Required Lenders as it reasonably deems appropriate or it will first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take such action.  Despite any other provision of this Section 2.19, the LC Issuer will in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and that request and any action taken or failure to act due to that request will be binding on the Lenders and any future holders of a participation in any LC.


2.19.9.    Indemnification.  The Borrowers will indemnify and hold harmless each Lender, the LC Issuer and the Administrative Agent, and their respective directors, officers, administrative agents and employees from and against any and all claims, and damages, losses, liabilities, costs or expenses which a Lender, the LC Issuer or the Administrative Agent may incur (or which may be claimed against a Lender, the LC Issuer or the Administrative Agent by any Person) by reason of or in connection with the issuance, signing and delivery, transfer of or payment, or failure to pay under any LC or any actual or proposed use of any LC, including any claims, damages, losses, liabilities, costs, or expenses which the LC Issuer incurs by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the LC Issuer (but this does not affect any rights the Borrowers may have against a defaulting Lender) or (ii) by reason of or on account of the LC Issuer issuing any LC which specifies that the term “Beneficiary” included in the LC includes any successor by operation of law of the named Beneficiary, but which LC does not require that any drawing by any successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the LC Issuer, 














37





evidencing the appointment of such successor Beneficiary.  The Borrowers will not be required to indemnify any Lender, the LC Issuer or the Administrative Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under an LC complied with the terms of the LC or (y) the LC Issuer’s failure to pay under any LC after the presentation to it of a request strictly complying with the terms and conditions of the LC. Nothing in this Section 2.19.9 is intended to limit the obligations of the Borrowers under any other provision of this Agreement, provided that to the extent of any inconsistency between this Section 2.19.9 and Section 12.6.1, the provisions of this Section 2.19.9 shall control; and provided further that this Section 2.19.9 shall not apply to Taxes, which shall be exclusively governed by Section 3.3. 


2.19.10.    Lenders’ Indemnification.  Each Lender will, in accordance with its Pro Rata Share, indemnify the LC Issuer, its Affiliates and their respective directors, officers, administrative agents and employees (to the extent not reimbursed by the Borrowers) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except resulting from the indemnitees’ gross negligence or willful misconduct or the LC Issuer’s failure to pay under any LC after the presentation to it of a request strictly complying with the terms and conditions of the LC) that the indemnitees may suffer or incur in connection with this Section 2.19 or any action taken or omitted by the indemnitees under this Section 2.19.


2.19.11.    Existing Letters of Credit.  Each letter of credit issued and outstanding under the Existing Credit Agreement as of the date hereof will be deemed to constitute an LC issued under this Agreement on the date hereof for all purposes of the Loan Documents; provided that no additional LC fees or fronting fees will be payable with respect to such letters of credit under Section 2.19.4. for which LC fees and fronting fees have been paid in full.


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


		
	(a)
	fees pursuant to Section 2.5.2 shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender;




		
	(b)
	the Commitment and Outstanding Credit Exposure of such Defaulting Lender shall not be included for any purpose in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 11.2), provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender and further provided that any redetermination or affirmation of the Borrowing Base shall occur without the participation of the Defaulting Lender, but the Commitment (i. 












38





e., the Pro Rata Share of the Borrowing Base of a Defaulting Lender) will not be increased without the consent of the Defaulting Lender;
		
	(c)
	if any LC Obligations exists at the time a Lender becomes a Defaulting Lender then:  (i) all or any part of the LC Obligations of such Defaulting Lender shall be reallocated among the non-Defaulting Lenders in accordance with their respective Pro Rata Share (for the purpose of such reallocation the Defaulting Lender's Commitment will be disregarded in determining each non-Defaulting Lender's Pro Rata Share) but only to the extent (x) the sum of all non-Defaulting Lenders’ Outstanding Credit Exposures plus such Defaulting Lender’s LC Obligations does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 4.2 are satisfied at such time; (ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within two Business Days following notice by the Administrative Agent (x) first, collateralize such Defaulting Lender’s LC Obligations (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.19.10 for so long as such LC Obligations are outstanding; (iii) if the Borrowers cash collateralizes any portion of such Defaulting Lender’s LC Obligations pursuant to this Section 2.20(c), the Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.19.4 with respect to such Defaulting Lender’s LC Obligations during the period such Defaulting Lender’s LC Obligations are cash collateralized; (iv) if the LC Obligations of the non-Defaulting Lenders are reallocated pursuant to this Section 2.20(c), then the fees payable to the Lenders pursuant to Section 2.19.4 and Section 2.12(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Pro Rata Shares; or (v) if any Defaulting Lender’s LC Obligations are neither cash collateralized nor reallocated pursuant to this Section 2.20(c), then, without prejudice to any rights or remedies of the LC Issuer or any Lender hereunder, all commitment fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Obligation) and letter of credit fees payable under Section 2.19.4 with respect to such Defaulting Lender’s LC Obligation shall be payable to the LC Issuer until such LC Obligations are cash collateralized and/or reallocated; and


		
	(d)
	so long as any Lender is a Defaulting Lender, the LC Issuer shall not be required to issue, amend or increase any LC, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrowers in accordance with Section 2.20(c), and participating interests in any such newly issued or increased LC shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and Defaulting Lenders shall not participate therein). In the event that the Administrative Agent, the Borrowers and the LC Issuer each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Obligations of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders as the 










39





Administrative shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Pro Rata Share.
2.21    Ratable Payments.  If any Lender, whether by setoff or otherwise, has payment made to it on its Outstanding Credit Exposure (other than payments received under Article 3) in a greater proportion than that received by any other Lender, such Lender agrees, promptly on demand, to purchase a portion of the Total Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Total Outstanding Credit Exposure.  If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations (other than its Rate Management Obligations, if any) or such amounts which may be subject to setoff, such Lender agrees, promptly on demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Total Outstanding Credit Exposure.  


ARTICLE 3
YIELD PROTECTION; TAXES


3.1    Yield Protection.  If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in its interpretation or administration by any governmental or quasi-governmental authority, central bank, or comparable agency charged with its interpretation or administration thereof or compliance by any Lender or applicable banking address of the LC Issuer with any request or directive of any such authority, central bank or comparable agency:


(i)    imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit, or similar requirement against assets of, deposits with (or for the account of), or credit extended by, any Lender or the LC Issuer (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances): or
(ii)    imposes any other condition the result of which is to increase a Lender’s cost, the interbank eurocurrency deposit market cost or the LC Issuer’s costs of making, funding or maintaining its Eurodollar Loans or of issuing or participating in LCs, or reduces any receivable of a Lender, the interbank eurocurrency deposit market or the LC Issuer in connection with its Eurodollar Loans, LCs or participations therein, or requires any Lender, the interbank Eurocurrency deposit market or the LC Issuer to make any payment calculated by reference to the amount of Eurodollar Loans, LCs or participations therein held or interest or LC Fees received by it, by an amount deemed material by such Lender or the LC Issuer as the case may be and the result of any of the foregoing is to increase the cost to such Lender or the LC Issuer, as the case may be, of making or maintaining its Eurodollar Loans or Commitment or of issuing or participating in LCs or to reduce the return received by such Lender, the interbank eurocurrency deposit market or the LC Issuer, as the case may be, in connection with such Eurodollar Loans, Commitment, LCs or participations therein, 










40





then, within 15 days of demand by the Administrative Agent or the LC Issuer, as the case may be, to Unit, the Borrowers will pay Administrative Agent for the account of the Lender or the LC Issuer, as the case may be, that additional amount or amounts as will compensate the Lender or the LC Issuer, as the case may be, for the increased cost or reduction in the amount received by it; provided that the Borrowers shall not be required to compensate a Lender or the LC Issuer pursuant to this Section 3.1 for any increased costs or reductions incurred more than 365 days prior to the date that such Lender or the LC Issuer, as the case may be, notifies Unit of the change giving rise to  such increased costs or reduction and of the Lender's or the LC Issuer's intentions to claim compensation therefor.
The foregoing provisions of this Section 3.1 shall not apply to Taxes, which shall be governed exclusively by Section 3.3.
3.2    Changes in Capital Adequacy Regulations.  If a Lender or the LC Issuer determines, in good faith, the amount of capital required or expected to be maintained by the Lender or the LC Issuer, or any corporation controlling the Lender or the LC Issuer is increased as a result of a Change, then, within 15 days of demand to Unit by the Lender or the LC Issuer, the Borrowers will pay the Lender or the LC Issuer the amount necessary to compensate the shortfall in the rate of return on the portion of the increased capital which the Lender or the LC Issuer determines in good faith  is attributable to this Agreement, its Outstanding Credit Exposure or its Commitment (after taking into account the Lender’s or the LC Issuer’s policies as to capital adequacy). “Change“ means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or the LC Issuer or any corporation controlling any Lender or the LC Issuer. “Risk-Based Capital Guidelines“ means (i) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to the regulations adopted prior to the date of this Agreement.  Notwithstanding anything in this Agreement to the contrary, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder, issued in connection therewith or in implementation thereof, and (ii) all requests, proposed or final rules, interpretations, guidelines and directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, will in each case be deemed to be “Change”, regardless of the date enacted, adopted, issued or implemented.


3.3    Taxes.  (i) All payments by the Borrowers to or for the account of any Lender, the LC Issuer or the Administrative Agent or under any Note or LC Application will be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes, unless such withholding is required by any law.  If the Borrowers are required by law to deduct Indemnified Taxes or Other Taxes from any payment to a Lender, the LC Issuer, or the Administrative Agent, to the extent not prohibited by applicable law, (a) the payment will be increased so that after 












41





making all required deductions (including deductions applicable to payments under this Section 3.3) the Lender, the LC Issuer, or the Administrative Agent (as the case may be) receives an amount equal to the payment it would have received had no deductions been made, (b) the Borrowers will make the deductions, (c) the Borrowers will pay the full amount deducted to the relevant authority in accordance with applicable law, and (d) the Borrowers will furnish Administrative Agent a copy of a receipt evidencing payment within 30 days after the payment is made.


		
	(i)
	In addition, without duplication of any payments made pursuant to Section 3.3 (i), the Borrowers will pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.




		
	(ii)
	The Borrowers agrees to indemnify the Administrative Agent, the LC Issuer, and each Lender for the full amount of Indemnified Taxes or Other Taxes paid by the Administrative Agent, the LC Issuer or a Lender and any liability (including penalties, interest and expenses) associated with those payments.  Payments properly due under this indemnification will be made within 30 days following the date the Administrative Agent, the LC Issuer or a Lender requests payment.




		
	(iii)
	If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country (or any of their political subdivisions) asserts a claim that the Administrative Agent did not properly withhold tax from payments to or for the account of any Lender because the appropriate form was not delivered or properly completed by such Lender, because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason, then such Lender will indemnify the Administrative Agent, fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax, withholding for the tax, or otherwise, including penalties and interest, and any taxes imposed by any jurisdiction on amounts payable to the Administrative Agent under this subsection, together with all related costs and expenses (including attorney’s fees and time charges of attorneys for the Administrative Agent.  The obligations of the Lenders under this Section 3.3(iii) will survive the payment of the Obligations and termination of this Agreement.  Any liability under this Section 3.3(iii) will not be a liability of the Borrowers.




		
	(iv)
	Any Lender or LC Issuer that is entitled to an exemption from or reduction of withholding Taxes (including backup withholding Taxes) with respect to payments under this Agreement shall deliver to the Borrowers (with a copy to the Administrative Agent), at the time or times upon the reasonable request of the Borrowers, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrowers as will permit such payments to be made without withholding or at a reduced rate of withholding; provided, no such Lender or LC Issuer will be required to deliver or submit copies of any tax returns or schedules therewith.


















42





		
	(v)
	If the Administrative Agent, a Lender or an LC Issuer determines, in its reasonable discretion, that it has received a refund or credit of any Taxes or Other Taxes as to which it has been indemnified by any Borrower or with respect to which any Borrower has paid additional amounts pursuant to this Section 3.3, it shall pay over such refund to such Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 3.3 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all reasonable out-of-pocket expenses of the Administrative Agent, such Lender or such LC Issuer and without interest (other than any interest paid by the relevant Governmental Authority with regard to the refund or credit); provided that such Borrower, upon the request of the Administrative Agent, such Lender or such LC Issuer, agrees to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or such LC Issuer in the event the Administrative Agent, such Lender or such LC Issuer is required to repay such refund to such Governmental Authority.




		
	(vi)
	If a payment made to a Lender or L/C Issuer under any Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender or L/C Issuer fails to comply with any requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender or L/C Issuer shall deliver to the Borrowers and the Administrative Agent at the time or times prescribed by applicable law and at such time or times reasonably requested by the Borrowers or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrowers or the Administrative Agent as may be necessary for the Borrowers and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender or such L/C Issuer has complied with such Lender’s or such L/C Issuer’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.  Solely for purposes of this clause (v), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.




		
	(vii)
	To the extent that the relevant documentation provided pursuant to this Section 3.3 is rendered obsolete or inaccurate in any material respect as a result of changes in circumstances with respect to the status of a Lender or a L/C Issuer, such Lender or such L/C Issuer shall, to the extent permitted by applicable law, deliver to the Borrowers and the Administrative Agent revised and/or updated documentation  or promptly notify the Borrowers and the Administrative Agent in writing of its legal inability to do so.




		
	(viii)
	For purposes of determining withholding Taxes imposed under FATCA, from and after the effectiveness of the Second Amendment, the Borrowers and the Administrative Agent shall treat (and the Lenders and the L/C Issuers hereby authorize the Administrative Agent to treat) each of the Loans as not qualifying 
















43





as “grandfathered obligations” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).


3.4    Availability of Eurodollar Advances.  If a Lender determines that maintenance of its Eurodollar Loans at a suitable banking location would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, then, upon notice by that Lender to the Borrowers and the Administrative Agent, such Lender’s obligation to continue to make or convert Eurodollar Loans shall be suspended until that Lender notifies the Borrowers and the Administrative Agent that the circumstances giving rise to such determination no longer exist and (ii) any Eurodollar Advances of that Lender shall be converted to Floating Rate Advances, to the extent required to comply with such Laws or change, subject to the payment of any funding indemnification amounts required by Section 3.5.  If the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then, upon notice by the Required Lenders to the Borrowers and the Administrative Agent, the availability of Eurodollar Advances, and continuations thereof and conversions thereto, will be suspended to the extent required to comply with such Laws or change until the Required Lenders notify the Borrowers and the Administrative Agent that the circumstances giving rise to such determination no longer exist and (ii) require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.5.


3.5    Funding Indemnification.  If for any reason a payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period or a Eurodollar Advance is not made on the date specified by the Borrowers for any reason other than a breach of this Agreement by one or more Lenders, the Borrowers will indemnify each Lender for any resulting loss or cost incurred by it.


3.6    Mitigation Obligations.  If any Lender requests compensation under Sections 3.1, 3.2 or 3.4 or if any Credit Party is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender or indemnify any Lender pursuant to Section 3.3, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Sections 3.1, 3.2, 3.3 or 3.3, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender.  


3.7    Replacement Lenders.  If a Lender (i) has notified Unit and the Administrative Agent of the circumstances described in Sections 3.1 or 3.4, (ii) has required Borrowers to make payments for Indemnified Taxes or Other Taxes under Section 3.3, (iii) becomes a Defaulting Lender, (iv) is a Non-Extending Lender under Section 3.8, or (v) objects to an increase in the Borrowing Base proposed by the Administrative Agent under the provisions of Section 2.6.2, then Unit may, at its sole cost, expense and effort, within ninety (90) days of Unit’s learning of any of the items in (i) - (v) provided that no Event of Default then exists, terminate, in whole but not in part, the Commitment of that Lender (other than the Administrative Agent) (a “Terminated 
















44





Lender“), on ten (10) days’ prior written notice to the Terminated Lender and the Administrative Agent (a “Notice of Termination“) of Unit's decision under this Section 3.7.  If, at any time during the ninety day period and before Unit issues a Notice of Termination, the Terminated Lender notifies Unit in writing that the circumstances giving rise to the notice, event or circumstance no longer apply or the Terminated Lender otherwise withdraws its request for additional compensation or approves the proposed Borrowing Base increase tendered by the Administrative Agent, as the case may be, then Unit will no longer be permitted to terminate the Commitment of that Lender by reason of the particular circumstances that no longer apply, the request that was withdrawn or the Borrowing Base increase that was approved, as the case may be.


To effect the termination of the Commitment of the Terminated Lender, Unit will: obtain either or both (i) an agreement by one or more Lenders to increase their Commitment or Commitments or (ii) an agreement by one or more other banking or lending institutions to become parties to this Agreement in place and instead of Terminated Lender and agree to accept a Commitment or Commitments; provided, however, that the new banking or lending institutions are reasonably acceptable to the Administrative Agent and become parties by executing an Assignment (the Lenders or other banking institutions that agree to accept in whole or in part the Commitment of the Terminated Lender being referred to herein as the “Replacement Lenders“) without recourse from the Terminated Lender, and that the aggregate increased and/or accepted Commitments of the Replacement Lenders under clauses (i) and (ii) above equal the Commitment of the Terminated Lender.


The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the “Lender Termination Date“), and within twenty (20) days of the Notice of Termination, Unit shall designate in writing the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its Commitment and, if there will be more than one Replacement Lender, the portion of the Terminated Lender’s Commitment to be assigned to each Replacement Lender.


On the Lender Termination Date, (i) the Terminated Lender shall by execution and delivery of an Assignment assign, without recourse, its Commitment and all of its interests, rights and obligations under this Agreement and the related Loan Documents to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the Pro Rata Share of the Terminated Lender’s Commitment to be assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders each of its Loans (if any) then outstanding and participation interests in Letters of Credit (if any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender shall endorse its Note, if any, payable without recourse, representation or warranty to the order of the Replacement Lender or Replacement Lenders (Pro Rata Share as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Note, if any, or Commitment held by the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid principal amount (including its participation in and Pro Rata Share of the LC Exposure) plus interest, facility fees, Commitment Fee and other fees accrued and unpaid to the Lender Termination Date, and (iv) the Replacement Lender or Replacement Lenders will thereon (pro rata as aforesaid) succeed to and be substituted in all respects for the Terminated Lender with like effect as if becoming a Lender under the terms of Section 14.3, and the Terminated Lender will have 


















45





the rights and benefits of an assignor under Section 14.3.  To the extent not in conflict, the terms of Section 14.3 shall supplement the provisions of this Section 3.7. For each assignment made under this Section 3.7, the Replacement Lender shall pay to the Agent the processing fee provided for in Section 14.3.  The Borrower will be responsible for the concurrent payment of any breakage costs associated with termination and Replacement Lenders, as set forth in Section 3.5.


3.8    Extension of Maturity Date.


3.8.1.    Requests for Extension.  Unit may, by notice to the Administrative Agent (who shall promptly notify the Lenders) not earlier than eighteen (18) months and not later than twelve (12) months before the stated Facility Termination Date then in effect (the “Existing Maturity Date”), request that each Lender extend the Lender’s Facility Termination Date for an additional one (1) year period from the Existing Maturity Date; but the Borrowers may request only two extensions under this Agreement and Borrowers will pay at the closing of an extension a reasonable extension fee, the amount of which will be negotiated and agreed to by the Lenders and Unit.


3.8.2.    Lender Elections to Extend.  Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given not later than the date (the “Notice Date”) that is sixty (60) days after Unit has given notice in accordance with Section 3.8.1, advise the Administrative Agent whether or not the Lender agrees to the extension (and each Lender that determines not to so extend its Facility Termination Date (a “Non-Extending Lender”) and shall notify the Administrative Agent of that fact promptly after that determination (but in any event no later than the Notice Date) and any Lender that does not so advise the Administrative Agent on or before the Notice Date shall be deemed to be a Non-Extending Lender. The election of any Lender to agree to the extension shall not obligate any other Lender to so agree.


3.8.3.    Notification by Administrative Agent.  The Administrative Agent shall notify the Borrower of each Lender’s determination under this Section no later than the date seven (7) days after the Notice Date (or, if the date is not a Business Day, on the next succeeding Business Day).


3.8.4.    Additional Commitment Lenders.  The Borrowers shall have the right on or before the Existing Maturity Date to replace each Non-Extending Lender with, and add as “Lenders” under this Agreement one or more Replacement Lenders (each, an “Additional Commitment Lender“) as provided in Section 3.7, each of which Additional Commitment Lenders shall have entered into an Assignment and Assumption under which the Additional Commitment Lender shall, effective as of the Existing Maturity Date, undertake a Commitment (and, if any Additional Commitment Lender is already a Lender, its Commitment will be in addition to the Lender’s Commitment on that date).


3.8.5.    Minimum Extension Requirement.  Only if the total of the Commitments of the Lenders that have agreed to extend their Facility Termination Date and the additional Commitments of the Additional Commitment Lenders is more than 50% of the total amount of the Commitments in effect immediately before the Existing Maturity 














46





Date, then, effective as of the Existing Maturity Date, the Facility Termination Date of each Lender (other than each Non-Extending Lender) and of each Additional Commitment Lender will be extended to the date which is one year after the Existing Maturity Date.  If that date is not a Business Day, then the Facility Termination Date as extended will be the next preceding Business Day.  Each Additional Commitment Lender will as a result become a “Lender” for all purposes of this Agreement.


3.8.6.    Conditions to Effectiveness of Extensions.  Notwithstanding the above provisions of this Section, the extension of the Facility Termination Date will not be effective with respect to any Lender unless:


		
	(i)
	no Default, Event of Default or Deficiency has occurred and is continuing on the date of the extension and after giving effect to the extension;




		
	(ii)
	the representations and warranties contained in this Agreement are true and correct on and as of the date of the extension and after giving effect to the extension, as though made on and as of that date (or, if any representation or warranty is expressly stated to have been made as of a specific date, as of that specific date); and




		
	(iii)
	on the Facility Termination Date of each Non-Extending Lender, the Borrower prepays any Obligations (other than any Rate Management Obligations owed to such Non-Extending Lender) outstanding on that date to each Non-Extending Lender (and pays any additional amounts required under Section 3.5).




3.8.7.    Conflicting Provisions.  This Section 3.8 will supersede any conflicting provisions in Section 11.2.

ARTICLE 5
REPRESENTATIONS AND WARRANTIES


The Credit Parties represent and warrant to the Lenders that as of the Fourth Amendment Effective Date:


5.1    Existence and Good Standing.  Each Credit Party is a corporation or limited liability company, duly and properly incorporated or organized, as the case may be, validly existing and (to the extent applicable to such entity) in good standing under the laws of its 












49





jurisdiction of incorporation or organization and has all requisite authority to carry on its business in each jurisdiction as now conducted.


5.2    Authorization and Validity.  Each Credit Party has the power and authority and legal right to execute and deliver the Loan Documents to which it is a party and to perform its obligations thereunder. The authentication and delivery by each Credit Party of the Loan Documents to which it is a party and the performance of its obligations thereunder have been duly authorized by proper corporate or limited liability company proceedings. The Loan Documents to which a Credit Party is a party constitute legal, valid and binding obligations of that Credit Party enforceable against it in accordance with their terms, except as may be limited by bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally and general principles of equity (“Enforceability Exceptions”).


5.3    No Conflict; Government Consent.  Neither the authentication and delivery of the Loan Documents by any of the Credit Parties which is a party to those documents, nor the consummation of the transactions contemplated by the Loan Documents, nor compliance with the provisions of the Loan Documents will violate in any material respect (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Credit Parties, (ii) any of the Credit Parties’ articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which any of the Credit Parties is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default, or result in, or require, the creation or imposition of any Lien in, of, or on the Property of the Credit Parties under the terms of any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the applicable Credit Parties, and the failure of which to obtain could reasonably be expected to have a Material Adverse Effect is required to be obtained by the Credit Parties in connection with the authentication and delivery of the Loan Documents, the borrowings under this Agreement, the payment and performance by the Borrowers of the Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents.


5.4    Financial Statements.  The audited annual and unaudited quarterly, consolidated financial statements of Unit and its consolidated Subsidiaries previously delivered to the Lenders were prepared in accordance with GAAP (except that the unaudited interim financial statements were subject to normal and recurring year-end adjustments) in effect on the date the statements were prepared and fairly present, in all material respects, the consolidated financial position and consolidated results of operations and cash flows of Unit and its consolidated subsidiaries at that date and the consolidated results of their operations for the period then ended.


5.5    Material Adverse Effect.  Since the filing of Unit’s most recent SEC Form 10-K on February 27, 2018, there has been no change in the business, Property, prospects, condition (financial or otherwise) or results of operations of the Credit Parties which could reasonably be expected to have a Material Adverse Effect.  There is no fact known to the Borrowers which has a Material Adverse Effect or in the future is reasonably likely to have (so far as the Credit Parties 










50





can now foresee) a Material Adverse Effect and which has not been set forth in this Agreement or the other documents, certificates and statements furnished to the Administrative Agent by or on behalf of the Credit Parties before, or on, the date of this Agreement.


5.6    Taxes.  The Credit Parties have filed all United States federal Tax returns and all other material Tax returns which are required to be filed and have paid all Taxes due under those returns or under any assessment received by the Credit Parties or any of their Subsidiaries, except (i) Taxes, if any, that are being contested in good faith and as to which adequate reserves have been provided in accordance with GAAP, and (ii) other Taxes where the failure to file or the failure to timely pay could not reasonably be expected to have a Material Adverse Effect. No material tax Liens have been filed and no material claims are being asserted with respect to any Taxes. 


5.7    Litigation and Contingent Obligations.  There is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their officers, threatened against or affecting the Credit Parties which could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the making of any Credit Extensions.  Other than any liability incident to any litigation, arbitration or proceeding which could not reasonably be expected to have a Material Adverse Effect, the Credit Parties have no material Contingent Obligations not provided for or disclosed in the financial statements referred to in Section 5.4 except as set forth on Schedule 7 of this Agreement.


5.8    Subsidiaries.  The Disclosure Schedule contains an accurate list of all Subsidiaries of Unit as of the date of this Agreement, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or other ownership interests owned by the Unit or the other Credit Parties.  All of the issued and outstanding shares of capital stock or other ownership interests of the Subsidiaries have been (to the extent those concepts are relevant with respect to those ownership interests) duly authorized and issued and are fully paid and non-assessable.

Agreement) as required by the Administrative Agent or the Required Lenders in connection with the Subsidiary Guaranty instruments executed from time to time by Material Subsidiaries under this Section 9.1.


9.2    Releases of Guarantees.  If, as a result of the consummation of any transaction permitted by this Agreement, any Subsidiary Guarantor ceases to be a Subsidiary of Unit, the guarantee of such Subsidiary Guarantor of the Obligations shall be automatically discharged and released without any further action by any Credit Party or any other Person effective as of the time of such transaction.  Upon request of Unit, the Administrative Agent shall take (at the Credit Parties’ cost), and the Lenders hereby authorize the Administrative Agent to take, such actions as shall be reasonably requested to evidence the termination and release of the guarantee of such Subsidiary Guarantor.

ARTICLE 11
ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES


11.1    Acceleration.
  
11.1.1. If any Event of Default described in Section 10.1.6 or 10.1.7 occurs with respect to the Credit Parties, the obligations of the Lenders to make Advances and Loans hereunder and the obligation and power of the LC Issuer to issue LCs will automatically terminate and the Obligations (other than Rate Management Obligations owed to Lender Counterparties) will immediately become due and payable without any election or action on the part of the Administrative Agent, the LC Issuer or any Lender and the Credit Parties will be and become thereby unconditionally obligated, without any further notice, act or demand, to deposit in an account with the Administrative Agent an amount in immediately available funds equal to the amount of LC Obligations in cash or cash equivalents reasonably satisfactory to the Administrative Agent, which funds will be applied pursuant to Section 11.1.2. If any other Event of Default occurs and is continuing, the Required Lenders (or the Administrative Agent with the consent of the Required Lenders) may (a) terminate or suspend the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue LCs, or declare the Obligations (other than Rate Management Obligations owed to Lender Counterparties) to be due and payable, or both, in which event such Obligations will become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrowers hereby expressly waive, and (b) on notice to the Borrowers and in addition to the continuing right to demand payment of all amounts payable under this Agreement, make demand on the Borrowers to pay, and the Borrowers will, forthwith on such demand and without any further notice or act, immediately pay to the Administrative Agent the amount in immediately available funds equal to the amount of such LC Obligations, which funds will be applied pursuant to Section 11.1.2.
















78





11.1.2. The Administrative Agent may at any time or from time to time, after such funds are deposited with the Administrative Agent, apply such funds to the payment of the Obligations in accordance with Section 11.4 and any other amounts as may have become due and payable by the Credit Parties to the Lenders or the LC Issuer under the Loan Documents.  Such funds (to the extent not applied as aforesaid) will be returned to the Borrowers (i) after all such Obligations and other amounts have been paid in full or (ii) within three (3) Business Days after all Events of Default have been cured or waived.


11.2    Amendments. Subject to the provisions of this Section 11.2, the Required Lenders (or the Administrative Agent with the consent in writing of the Required Lenders) and the Credit Parties may enter into supplemental agreements for the purpose of adding or modifying any provisions to the Loan Documents to which they are parties or changing in any manner the rights of the Lenders or the Borrowers under this Agreement or waiving any Default, Event of Default or Deficiency under this Agreement, provided that no supplemental agreement will, without the consent of all of the Lenders:


		
	(i)
	Extend the final maturity of any Loan, or extend the expiration date of an LC to a date after the Facility Termination Date or postpone any regularly scheduled payment of principal of any Loan or forgive all or any portion of the principal amount thereof or any Reimbursement Obligation related thereto, or reduce the rate or extend the time of payment of interest or fees thereon or Reimbursement Obligations related thereto;




		
	(ii)
	Reduce the percentage specified in the definition of Required Lenders or eliminate, delete or modify the Borrowing Base concept of Section 2.6;




		
	(iii)
	Extend the Facility Termination Date (other than pursuant to Section 3.8), or reduce the amount or extend the payment date for, the mandatory principal payments required under Section 2.8.2, or increase the (a) Maximum Credit Amount, (b) Total Commitment Amount, (c) Borrowing Base (other than pursuant to Section 2.6), (d) amount of the Commitment of any non-consenting Lender under this Agreement or (e) commitment to issue LCs (other than as provided in the definition of “LC Sublimit”); or




		
	(iv)
	Amend this Section 11.2 or permit the Borrowers to assign their rights under this Agreement.




Further provided, that no amendment of any provision of this Agreement relating to the Administrative Agent will be effective without the written consent of the Administrative Agent, and no amendment of any provision relating to the LC Issuer will be effective without the written consent of the LC Issuer.


11.3    Preservation of Rights.  No delay or omission of the Lenders, the LC Issuer or the Administrative Agent to exercise any right under the Loan Documents will impair such right or be construed to be a waiver of any Default, Event of Default or Deficiency or an acquiescence in such Default, Event of Default or Deficiency, and the making of a Credit Extension notwithstanding the existence of a Default, Event of Default or Deficiency or the inability of the 












79





Credit Parties to satisfy the conditions precedent to such Credit Extension will not constitute any waiver or acquiescence. Any single or partial exercise of any such right will not preclude other or further exercise of such right or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever will be valid unless in writing executed by the Lenders required under Section 11.2, and then only to the extent specifically set forth in writing.  All remedies contained in the Loan Documents or by law or equity afforded will be cumulative and will be available to the Administrative Agent, the LC Issuer and the Lenders until the Obligations have been paid in full.


11.4    Allocation of Payments After Event of Default.  Notwithstanding any other provisions of this Agreement to the contrary, after the occurrence and during the continuance of an Event of Default, all amounts collected or received on or in respect of the Obligations (or other amounts owing under the Loan Documents in connection therewith) shall be paid over or delivered as follows:


FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable attorneys' fees) of the Administrative Agent, the LC Issuer or the Lenders in connection with enforcing the rights and remedies of the Administrative Agent or the Lenders under the Loan Documents and any protective advances made with respect thereto or otherwise with respect to the Obligations owing to the Lenders, the LC Issuer or the Administrative Agent;


SECOND, to payment of any fees owed to the Lenders, the LC Issuer or the Administrative Agent hereunder;


THIRD, to the payment of all accrued interest and fees on or in respect of the Obligations;


FOURTH, to the payment of the outstanding principal amount of the Obligations hereunder (including the payment or cash collateralization of the outstanding LC Obligations and Rate Management Obligations owed to Lender Counterparties being paid on a pari passu basis with the repayment of other Obligations);


FIFTH, to all other Obligations hereunder and other obligations which shall have become due and payable under the Loan Documents otherwise and not repaid pursuant to clauses "FIRST" through "FOURTH" above; and


SIXTH, to the payment of the surplus, if any, to Unit or such other Persons as may be lawfully entitled to receive such surplus.


In carrying out the foregoing, (i) amounts received shall be applied in the order provided until exhausted prior to application to the next succeeding category to the Administrative Agent or in accordance with each Lender's Pro Rata Share, as applicable, (unless a Lender is a Defaulting Lender); and (ii) to the extent that any amounts available for distribution pursuant to clause "FOURTH" above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be held by the Administrative Agent in a cash collateral account and applied (A) first, to reimburse the LC Issuer for any drawings under such Letters of Credit and (B) then, following the expiration of all Letters of Credit, to all other obligations of the types 








80





described in clauses "THIRD" and "FOURTH" above in the manner provided in this Section 11.4. Excluded Swap Obligations with respect to any Subsidiary Guarantor shall not be paid with amounts received from such Subsidiary Guarantor or its assets, but appropriate adjustments shall be made to payments from other Credit Parties to preserve the allocation to Obligations otherwise set forth above in this Section 11.4.
ARTICLE 12
GENERAL PROVISIONS

12.3    Headings.  Section headings in the Loan Documents are for convenience of reference only, and will not govern the interpretation of any of the provisions of the Loan Documents.


12.4    Entire Agreement.  The Loan Documents embody the entire agreement and understanding among the Credit Parties, the Administrative Agent, the LC Issuer and the Lenders and supersede all prior agreements and understandings among the Credit Parties, the Administrative Agent, the LC Issuer and the Lenders relating to the subject matter of the Loan Documents other than the Administrative Agent Fee Letter, all of which will survive and remain in full force and effect during the term of this Agreement.


12.5    Several Obligations; Benefits of this Agreement.  The respective obligations of the Lenders hereunder are several and not joint and no Lender will be the partner or Administrative Agent of any other (except to the extent to which the Administrative Agent is authorized to act in such capacity).  The failure of a Lender to perform any of its obligations hereunder will not relieve any other Lender from any of its obligations hereunder.  This Agreement will not be construed so as to confer any right or benefit on any Person other than the parties to this Agreement and their respective successors and assigns.


12.6    Expenses; Indemnification. 


12.6.1.    Expenses.  The Borrowers will promptly reimburse the Administrative Agent for any filing and recording fees, reasonable costs and out-of-pocket expenses (including reasonable attorneys’ fees), time charges and expenses advanced of attorneys for the Administrative Agent or for any of the Lenders) paid or incurred by the Administrative Agent or the Co-Syndication Agents in connection with the preparation, negotiation, execution, closing, delivery, syndication, review, amendment, waiver, consent or modification, refinancing, Lien perfection, administration, collection and enforcement of the Loan Documents, regardless of whether or not the transactions 
















81





provided for in this Agreement are eventually closed and regardless of whether or not any or all sums evidenced by the Notes are advanced to the Borrowers by the Lenders. 


12.6.2    Indemnification.  The Borrowers hereby also agree to indemnify against and, where applicable, reimburse for, the Administrative Agent, the Co-Syndication Agents, the LC Issuer and each Lender, its directors, officers and employees, all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, the prompt reimbursement of all legal fees and expenses of attorneys for the Administrative Agent, the Co-Syndication Agents, the LC Issuer or any of the Lenders in connection with (i) restructure as a part of loan work out or special asset modification or fees and expenses from enforcement or collection actions or proceedings, and (ii) collection and enforcement actions or proceedings, including litigation or preparation therefor whether or not the Administrative Agent, the Co-Syndication Agents, the LC Issuer or any Lender is a party to such litigation) which any of them may pay or incur in good faith as a result of this Agreement, the other Loan Documents, the transactions contemplated by the Loan Documents except to the extent that they are determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the party seeking indemnification, and (iii) any civil penalty or fine assessed by OFAC against, and all reasonable costs and expenses (including counsel fees and disbursements) incurred in connection with defense thereof, by the Administrative Agent or any Lender as a result of conduct of any Borrower or any Subsidiary that violates a sanction enforced by OFAC. 


The foregoing provisions of this Section 12.6 shall not apply to Taxes, which shall be governed exclusively by Section 3.3.  The obligations of the Borrowers under this Section 12.6 will survive the termination of this Agreement.


12.7    Severability of Provisions.  Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction will, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction.  The provisions of all Loan Documents are severable.


12.8    Environmental Indemnities.


Each of the Borrowers hereby agrees to indemnify, defend and hold harmless the Administrative Agent and the Lenders and their respective officers, directors, employees, agents, consultants, attorneys, contractors and their respective affiliates, successors or assigns, or transferees from and against, and reimburse said Persons in full with respect to, any and all loss, liability, damage, fines, penalties, costs and expenses, of every kind and character, including reasonable attorneys’ fees and court costs, known or unknown, fixed or contingent, occasioned by or associated with any claims, demands, causes of action, suits and/or enforcement actions, including any administrative or judicial proceedings, and any remedial, removal or response actions ever asserted, threatened, instituted or requested by any Persons, including any Governmental Authority, arising out of or related to:  (a) the breach of any representation or warranty of the Borrowers contained in Section 5.16; (b) the failure of the Borrowers to perform any of their respective covenants contained in Section 6.7; (c) the ownership, construction, 






82





occupancy, operation, use of the Credit Parties’ Properties prior to the date on which the Indebtedness and obligations secured hereby have been paid and performed in full; provided, however, this indemnity shall not apply with respect to matters caused by or arising solely from the Administrative Agent’s or the Lenders’ activities during any period of time the Administrative Agent or the Lenders acquire ownership of the Credit Parties’ Properties.


The indemnities contained in this Section 12.8 apply, without limitation, to any violation on or before the Release Date of any Environmental Laws and any liability or obligation relating to the environmental conditions on, under or about the Credit Parties’ Properties on or prior to the Release Date (including, without limitation:  (a) the presence on, on or in the Credit Parties’ Properties or release, discharge or threatened release on, on or from the Credit Parties’ Properties of any polluting substances generated, used, stored, treated, disposed of or otherwise released prior to the Release Date, and (b) any and all damage to real or personal property or natural resources and/or harm or injury including wrongful death, to persons alleged to have resulted from such release of any polluting substances regardless of whether the act, omission, event or circumstances constituted a violation of any Environmental Law at the time of its existence or occurrence). The term “release” shall have the meaning specified in applicable Environmental Laws and the terms “stored,” “treated” and “disposed” shall have the meanings specified in applicable Environmental Laws; provided, however, any broader meanings of such terms provided by applicable laws of the State of Oklahoma shall apply.


The provisions of this Section 12.8 shall be in addition to any other obligations and liabilities Credit Parties may have to the Administrative Agent or the Lenders at common law and shall survive the Release Date and shall continue thereafter in full force and effect.


The Administrative Agent and the Lenders agree that in the event that such claim, suit or enforcement action is asserted or threatened in writing or instituted against them or any of their officers, employers, agents or contractors or any such remedial, removal or response action is requested of them or any of their officers, employees, agents or contractors for which the Administrative Agent or the Lenders may desire indemnity or defense hereunder, the Administrative Agent or the Lenders shall give prompt written notification thereof to Unit.


Notwithstanding anything to the contrary stated herein, the indemnities created by this Section 12.8 shall only apply to losses, liabilities, damages, fines, penalties, costs and expenses actually incurred by the Administrative Agent or the Lenders as a result of claims, demands, actions, suits or proceedings brought by Persons who are not the beneficiaries of any such indemnity.  The Administrative Agent or the Lenders shall act as the exclusive agent for all indemnified Persons under this Section 12.8.  With respect to any claims or demands made by such indemnified Persons, the Administrative Agent shall notify Unit within ten (10) days after the Administrative Agent’s receipt of a writing advising the Administrative Agent of such claim or demand.  Such notice shall identify (i) when such claim or demand was first made, (ii) the identity of the Person making it, (iii) the indemnified Person and (iv) the substance of such claim or demand.  Failure by the Administrative Agent to so notify Unit within said ten (10) day period shall reduce the amount of the Credit Parties’ obligations and liabilities under this Section 12.8 by an amount equal to any damages or losses suffered by the Credit Parties resulting from any prejudice caused the Credit Parties by such delay in notification from the Administrative Agent.  On receipt of such notice, the Credit Parties shall have the exclusive right and obligation to 








83





contest, defend, negotiate or settle any such claim or demand through counsel of their own selection (but reasonably satisfactory to the Administrative Agent and the Lenders) and solely at Credit Parties’ own cost, risk and expense; provided, that the Administrative Agent and the Lenders, at their own cost and expense, shall have the right to participate in any such contest, defense, negotiations or settlement.  The settlement of any claim or demand hereunder by the Credit Parties, unless such settlement fully releases the Lenders from any and all liability thereon, may be made only on the prior approval of the Lenders of the terms of the settlement, which approval shall not be unreasonably withheld.


12.9    Nonliability of Lenders.  The relationship between the Borrowers on the one hand and the Lenders, the LC Issuer and the Administrative Agent on the other hand will, to the extent that relationship is the subject of this Agreement, be solely that of borrowers and lenders.  Neither the Administrative Agent, the Syndication Agents, the LC Issuer nor any Lender will have any fiduciary responsibilities to the Credit Parties.  Neither the Administrative Agent, the Syndication Agent, the LC Issuer nor any Lender undertakes any responsibility to the Credit Parties to review or inform the Credit Parties of any matter in connection with any phase of the Credit Parties’ business or operations.  The Credit Parties agree that neither the Administrative Agent, the Syndication Agent, the LC Issuer nor any Lender will have liability to the Credit Parties (whether sounding in tort, contract or otherwise) for losses suffered by the Credit Parties in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. Neither the Administrative Agent, the Syndication Agent, the LC Issuer nor any Lender will have any liability with respect to, and the Credit Parties hereby waive, release and agree not to sue for, any special, indirect or consequential damages suffered by the Credit Parties in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.


12.10    No Advisory or Fiduciary Responsibility.  In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), Borrowers acknowledge and agree that:  (i) (A) the arranging and other services regarding this Agreement provided by Administrative Agent are arm’s-length commercial transactions between Borrowers and their Affiliates, on the one hand, and Administrative Agent, on the other hand, (B) Borrowers have consulted their own legal, accounting, regulatory and tax advisors to the extent they have deemed appropriate, and (C) Borrowers are capable of evaluating, and understand and accept, the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; (ii) (A) Administrative Agent is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not and will not be acting ad an advisor, agent of fiduciary for Borrowers or any of their Affiliates, or any other Person and (B) Administrative Agent has not obligation to Borrowers or any of their Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in other Loan Documents; and (iii) Administrative Agent and its Affiliates may be engaged in a broad range of transactions that involve interest that differ from those of the Borrowers and their Affiliates, and the Administrative Agent has no obligation to disclose any of such interests to Borrowers or their Affiliates.  To the fullest extent permitted by law, Borrowers hereby waive and release any 










claims that it may have against Administrative Agent with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.


84







12.11    Confidentiality.  Each Lender agrees to hold as confidential any information which it may receive from the Credit Parties or any of its Subsidiaries under this Agreement or any other Loan Document in confidence, except for disclosure (i) to its Affiliates and to other Lenders and their respective Affiliates, (ii) to legal counsel, accountants, and other professional advisors to such Lender or to a Transferee (so long as such Persons are apprised of the confidential nature of such information), (iii) to regulatory officials, (iv) to any Person as requested under or as required by law, regulation, or legal process, (v) to any Person in connection with any legal proceeding relating to any of the Loan Documents to which such Lender is a party, (vi) to such Lender’s direct or indirect contractual counterparties in swap agreements, to legal counsel, accountants and other professional advisors to such counterparties or to any credit insurance provider relating to Borrowers and their obligations (so long as such Persons agree to be bound by the provisions of this Section 12.11), (vii) permitted by Section 14.4, (viii) to rating agencies if requested or required by such agencies in connection with a rating relating to the Advances, and (ix) of information that the Credit Parties have made available to the general public.


12.12    Disclosure.  The Borrowers and each Lender hereby acknowledge and agree that BOk and/or its Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Borrowers and/or their Subsidiaries.


12.13    Place of Payment.  All amounts to be paid by the Borrowers or the Subsidiary Guarantors under this Agreement will be paid in immediately available funds to the Administrative Agent at its principal banking offices at Bank of Oklahoma Tower, One Williams Center, Tulsa, Oklahoma 74192, Attention: Energy Department - 8th Floor, or at such other place as the Administrative Agent or the Required Lenders will notify Unit in writing.  If any interest, principal or other payment falls due on a date other than a Business Day, then (unless otherwise provided in this Agreement) such due date will be extended to the next succeeding Business Day, and such extension of time will in such case be included in computing interest, if any, in connection with such payment.


12.14    Interest.  It is the intention of the parties to this Agreement that the Lenders  conform strictly to usury laws applicable to it.  Accordingly, if the transactions contemplated by this Agreement would be usurious as to a Lender under laws applicable to it (including the laws of the United States of America or any other jurisdiction whose laws may be mandatorily applicable to Lenders notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: 


		
	(i)
	the total of all consideration which constitutes interest under law applicable to Lenders that is contracted for, taken, reserved, charged or received by Lenders under any of the Loan Documents or agreements or otherwise in connection with the Notes will under no circumstances exceed the Highest Lawful Rate allowed by such applicable law, and any excess will be canceled automatically 












and if theretofore paid will be credited by the Administrative Agent or the Lenders on the principal amount of the Obligations (or, to the extent that the principal amount of 


85





the Obligations will have been or would thereby be paid in full, refunded by Administrative Agent or the Lenders to the Borrowers); and 


		
	(ii)
	in the event that the maturity of any of the Notes is accelerated by, because of or resulting from an Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to Administrative Agent or the Lenders may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise will be canceled automatically by Lenders as of the date of such acceleration or prepayment and, if theretofore paid, will be credited by Administrative Agent or the Lenders on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations will have been or would thereby be paid in full, refunded by Lenders to the Borrowers). 




All sums paid or agreed to be paid to Administrative Agent or the Lenders for the use, forbearance or detention of sums due under this Agreement will, to the extent permitted by law applicable to Administrative Agent and/or the Lenders, be amortized, prorated, allocated and spread throughout the full term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans under this Agreement does not exceed the Highest Lawful Rate allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to Lenders on any date will be computed at the highest lawful rate applicable to Lenders under this Section 12.14; and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to Lenders would be less than the amount of interest payable to Lenders computed at the highest lawful rate applicable to such Lenders, then the amount of interest payable to Lenders regarding such subsequent interest computation period will continue to be computed at the Highest Lawful Rate applicable to Lenders until the total amount of interest payable to Lenders equals the total amount of interest which would have been payable to Lenders if the total amount of interest had been computed without giving effect to this Section 12.14. 


None of the terms and provisions contained in this Agreement or in any other Loan Document which directly or indirectly relate to interest will ever be construed without reference to this Section 12.14, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Highest Lawful Rate.


12.15    Automatic Debit of Borrowers’ Operating Account.  On Borrowers’ failure to pay all such costs and expenses owed by Borrowers under Section 12.6 of this Agreement within thirty (30) days of the Administrative Agent’s submission of invoices therefore, the Administrative Agent will pay such costs and expenses by debit to the operating account of Borrowers with the Administrative Agent without further or other notice to Borrowers.


12.16    Exceptions to Covenants.  The Borrowers are not permitted to take any action or fail to take any action which is permitted as an exception to any of the covenants contained in this 










Agreement or which is within the permissible limits of any of the covenants contained in this Agreement if such action or omission would result in the breach of any other covenant contained in this Agreement.




86





12.17    Conflict with Other Loan Documents.  To the extent the terms and provisions of any of the other Loan Documents are in conflict with the terms and provisions hereof, the terms and provisions of this Agreement will be deemed controlling.


12.18    Lost Documents.  On receipt of an affidavit of an officer of the Administrative Agent as to the loss, theft, destruction or mutilation of the Notes or Loan Documents which is not of public record, and, in the case of any mutilation, on the surrender and cancellation of the Notes or Loan Documents, the Borrowers or any Subsidiary Guarantors will issue, in lieu thereof, a replacement Note(s) or other Loan Documents in the same principal amount thereof (in the case of any of the Notes) and otherwise of like tenor.


12.19    Setoff.  At any time and from time to time during the continuance of any Event of Default, each Lender is hereby authorized to setoff and apply (a) any and all moneys, securities and other property (and the proceeds therefrom) of such Credit Party now or hereafter held or received by or in transit to such Lender from or for the account of such Credit Party, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits and deposit accounts (general or special, time or demand, provisional or final) of such Credit Party with such Lender, and (c) any other credits and claims of such Credit Party at any time existing against such Lender, including claims under certificates of deposit (excluding from the foregoing clauses (a) though (c) the accounts at BOk as specified on Schedule 6 (collectively, the “Excluded Accounts“)) against the Obligations then due and payable and held by such Lender (without notice to any Credit Party) and concerning any such action in clauses (a) through (c) taken by a Lender, prompt notice thereof shall be provided by such Lender to the Administrative Agent.  The rights of each Lender under this Section 12.19 are in addition to all other interests and rights of such Lender at common Law, under the Loan Documents, or otherwise.


12.20    Keepwell.  Each Credit Party that is a Qualified ECP Guarantor at the time the Subsidiary Guaranty or the grant of a security interest under the Loan Documents, in each case, by any Specified Loan Party becomes effective with respect to any Rate Management Obligation, hereby jointly and severally, absolutely, unconditionally and irrevocably undertakes to provide such funds or other support to each Specified Loan Party with respect to such Rate Management Obligation as may be needed by such Specified Loan Party from time to time to honor all of its obligations under its Subsidiary Guaranty and the other Loan Documents in respect of such Rate Management Obligation (but, in each case, only up to the maximum amount of such liability that can be hereby incurred without rendering such Qualified ECP Guarantor’s obligations and undertakings under this Section 12.20 voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount).  The obligations and undertakings of each Qualified ECP Guarantor under this Section 12.20 shall remain in full force and effect until the Obligations have been indefeasibly paid and performed in full.  Each Qualified ECP Guarantor intends this Section 12.20 to constitute, and this Section 12.20 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of, each Specified Loan Party for all purposes of the Commodity Exchange Act.

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

14.2    Participations.


14.2.1.    Permitted Participants; Effect.  Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time on obtaining the prior written consent of the Administrative Agent and Unit, sell to one or more banks or other entities (“Participants”) participating interests in any Outstanding Credit Exposure of such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents.  In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents will remain unchanged, such Lender will remain solely responsible to the other parties hereto for the performance of such obligations, such Lender will remain the owner of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrowers under this Agreement will be determined as if such Lender had not sold such participating interests, and the Borrowers and the Administrative Agent will continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents.  Voting Rights.  Each Lender will retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification 










or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders under the terms of Section 11.2 or of any other Loan Document. Benefit of Certain Provisions.  The Borrowers agree that each Participant will be deemed to have the right of setoff provided in Section 12.19 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender will retain the right of setoff provided in Section 12.19 with respect to the amount of participating 


92





interests sold to each Participant.  The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 12.19, agrees to share with each Lender, any amount received under the exercise of its right of setoff, such amounts to be shared in accordance with Section 2.21 as if each Participant were a Lender.  The Borrowers further agree that each Participant will be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment under Section 14.3, provided that (i) a Participant will not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the Lender 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 the Borrowers, and (ii) any Participant agrees to comply with the provisions of Section 3.3 to the same extent as if it were a Lender.


14.3    Assignments.


14.3.1.    Permitted Assignments.  Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other entities other than any Credit Party (“Purchasers“) all or any part of its rights and obligations under the Loan Documents.  Such assignment will be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto.  The consent of Unit, the Administrative Agent and the LC Issuer will be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or an Affiliate thereof; provided, however, that if a Default, Event of Default or Deficiency has occurred and is continuing, the consent of the Unit will not be required.  Such consent of Unit will not be unreasonably withheld or delayed.  Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate thereof will (unless each of the Credit Parties and the Administrative Agent otherwise consent) be in an amount not less than the lesser of (i) $15,000,000 or (ii) the remaining amount of the assigning Lender’s Commitment (calculated as at the date of such assignment) or outstanding Loans (if the applicable Commitment has been terminated).


14.3.2.    Effect; Effective Date.  On (i) delivery to the Administrative Agent of a notice of assignment, substantially in the form attached as Exhibit I to Exhibit C (a “Notice of Assignment“), together with any consents required by Section 14.3.1, and (ii) payment of a $2,500 fee to the Administrative Agent for processing such assignment, such assignment will become effective on the effective date specified in such Notice of Assignment.  The Notice of Assignment will contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment 












and Outstanding Credit Exposure under the applicable assignment agreement are “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA.  On and after the effective date of such assignment, such Purchaser will for all purposes be a Lender to this Agreement and any other Loan Document executed by or on behalf of the Lenders and will have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Credit Parties, the Lenders or the Administrative Agent will be required to release the transferor Lender with respect to the percentage of the Total Commitment and Outstanding Credit 


93





Exposure assigned to such Purchaser. On the consummation of any assignment to a Purchaser under this Section 14.3.2, the transferor Lender, the Administrative Agent and the Borrowers will, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender 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 under such assignment.


14.3.3    Register.  The Administrative Agent, acting solely for this purpose as an Administrative Agent of the Borrowers, will maintain at its main banking offices in Tulsa, Oklahoma, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender under the terms hereof from time to time (the “Register“).  The entries in the Register will be conclusive, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register under the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.  The Register will be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time on reasonable prior notice.


14.4    Dissemination of Information.  Subject to the confidentiality requirements of this Agreement, the Borrowers authorize each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee“) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Credit Parties and their Subsidiaries, including without limitation any information contained in any reports provided to Administrative Agent; provided that each Transferee and prospective Transferee agrees to be bound by this Agreement.


14.5    Tax Treatment.  If any interest in any Loan Document is transferred to any Transferee, the transferor Lender will cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.3(iv).


14.6    Procedure for Increases and Additional Lenders.  In the event that neither (i) a Default, an Event of Default or a Deficiency has occurred and remains uncured hereunder nor (ii) a Default, an Event of Default or a Deficiency would be caused by or result from the Borrowers’ exercise of the provisions of this Section 14.6, Unit, on behalf of the Borrowers may from time to time after the date of this Agreement request in writing to the Administrative Agent and each
