In the event that at maturity (stated or by acceleration), or at final payment of any Revolving Loan, the total amount of interest paid or accrued on such Revolving Loan is less than the amount of interest that would have accrued if the Contract Rate had at all times been in effect with respect thereto, then at such time, to the extent permitted by law, Borrower shall pay to the holder of such Revolving Loan an amount equal to the difference between (i) the lesser of the amount of interest that would have accrued if the Contract Rate had at all times been in effect and the amount of interest that would have accrued if the Maximum Lawful Rate had at all times been in effect, and (ii) the amount of interest actually paid on such Revolving Loan.

(g) Interest payable hereunder on each Eurodollar Loan shall be computed based on the number of actual days elapsed assuming that each calendar year consisted of 360 days. Interest payable hereunder on the Base Rate Loan shall be computed based on the actual number of days elapsed assuming that each calendar year consisted of 365 days (or 366 days in a leap year).

Section 2.6 Mandatory Prepayments. Upon the occurrence of any Borrowing Base Deficiency, Borrower shall make the mandatory prepayments of the Revolving Loan required by Section 4.5 hereof.

Section 2.7 Voluntary Prepayments. Borrower may, subject to Section 12.5 and the other provisions of this Agreement, prepay the principal of the Revolving Loan in whole or in part. Any partial prepayment shall be in a minimum amount of $100,000 and shall be in an integral multiple of $50,000.

Section 2.8 Voluntary Reduction of Commitments. Borrower may, by notice to Lender 3 Domestic Business Days prior to the effective date of any such reduction, reduce the Commitment in amounts not less than $250,000 and in an amount that is an integral multiple of $100,000. On the effective date of any such reduction, Borrower shall, to the extent required as a result of such reduction, make a principal payment on the Revolving Loan in an amount sufficient to cause the principal balance of the Revolving Loan then outstanding to be equal to or less than the Commitment as thereby reduced. Notwithstanding the foregoing, Borrower shall not be permitted to voluntarily reduce the Commitment to an amount less than the aggregate Letter of Credit Exposure.

Section 2.9 Termination of Commitment; Final Maturity of Revolving Loan. The Commitment shall terminate, and the entire outstanding principal balance of the Revolving Loan, all interest accrued thereon, all accrued but unpaid fees hereunder and all other outstanding Obligations shall be due and payable in full on the Termination Date.

Section 2.10 Application of Payments. Each repayment pursuant to Section 2.6, Section 2.7, Section 2.8, Section 2.9, and Section 4.5 shall be made together with accrued interest on the amount repaid to the date of payment, and shall be applied in accordance with Article III and the other provisions of this Agreement.

Section 2.11 Commitment Fee. On the Termination Date, on each Quarterly Date prior to the Termination Date, and, in the event the Commitment is terminated in their entirety prior to the Termination Date, on the date of such termination, Borrower shall pay to Lender, a commitment fee equal to the Commitment Fee Percentage in effect from day to day (applied on a per annum basis and computed on the basis of actual days elapsed and as if each calendar year consisted of 365 days (or 366 days in a leap year)) of the average daily Availability for the Fiscal Quarter (or portion thereof) ending on the date such payment is due.

Section 2.12 Origination, Agency and other Fees. Borrower shall (a) on the Closing Date pay to Lender an origination fee equal to 0.50% of the Initial Borrowing Base, and (b) pay to Lender and its Affiliates such other fees and amounts as Borrower shall be required to pay to Lender and its Affiliates from time to time pursuant to any separate agreement between Borrower and Lender or such Affiliates.

BORROWING BASE

Section 4.1 Reserve Report; Proposed Borrowing Base. The aggregate amount of credit available to Borrower under this Agreement shall be limited by a borrowing base (“Borrowing Base”) that shall be determined by Lender at the times and in accordance with the standards and procedures set forth in this Article IV. As soon as available and in any event by June 1 and December 1 of each year, commencing June 1, 2013, Borrower shall deliver to Lender a Reserve Report prepared as of the immediately preceding April 1 and October 1, respectively. Simultaneously with the delivery to Lender of each Reserve Report, Borrower shall notify Lender of the amount of the Borrowing Base that Borrower requests become effective on the next Redetermination Date (or such date promptly following such Redetermination Date as Lender shall elect).

Section 4.2 Scheduled Redeterminations of the Borrowing Base; Procedures and Standards. Based in part on the Reserve Reports made available to Lender pursuant to Section 4.1, Lender shall redetermine the Borrowing Base on or prior to the next Redetermination Date (or such date promptly thereafter as reasonably possible based on the engineering and other information available to Lender). Any Borrowing Base that becomes effective as a result of any Redetermination of the Borrowing Base shall be subject to the following restrictions: (a) such Borrowing Base shall not exceed the Borrowing Base requested by Borrower pursuant to Section 4.1 or Section 4.3 (as applicable), (b) such Borrowing Base shall not exceed the Commitment then in effect, and (c) such Borrowing Base shall be approved by Lender. Each Redetermination shall be made by Lender in its sole discretion. Without limiting such discretion, Borrower acknowledges and agrees that Lender (i) may make such assumptions regarding appropriate existing and projected pricing for Hydrocarbons as it deems appropriate in its sole discretion, (ii) may make such assumptions regarding projected rates and quantities of future production of Hydrocarbons from the Mineral Interests owned by Borrower as it deems appropriate in its sole discretion, (iii) may consider the projected cash requirements of the Credit Parties, (iv) is not required to consider any asset other than Proved Mineral Interests owned by Borrower that are subject to first and prior Liens in favor of Lender to the extent required by Section 5.1, and (v) may make such other assumptions, considerations and exclusions as Lender deems appropriate in the exercise of its sole discretion. It is further acknowledged and agreed that Lender may consider such other credit factors as it deems appropriate in the exercise of its sole discretion and shall have no obligation in connection with any Redetermination to approve any increase from the Borrowing Base in effect prior to such Redetermination. Promptly following any Redetermination of the Borrowing Base, Lender shall notify Borrower of the amount of the Borrowing Base as redetermined, which Borrowing Base shall be effective as of the date specified in such notice, and shall remain in effect for all purposes of this Agreement until the next Redetermination.

Section 4.3 Special Redetermination.

Any request by Borrower pursuant to this Section 4.3(a) shall be submitted to Lender and at the time of such request Borrower shall (A) deliver to Lender a Reserve Report, and (B) also notify Lender of the Borrowing Base requested by Borrower in connection with such Special Redetermination.

(b) Any Special Redetermination shall be made by Lender in accordance with the procedures and standards set forth in Section 4.2; provided, that, no Reserve Report will be required to be delivered to Lender in connection with any Special Redetermination requested by Lender pursuant to Section 4.3(a).

Section 4.4 Asset Disposition Adjustment. In addition to the Redeterminations pursuant to Section 4.2 and Section 4.3, Lender shall be permitted to redetermine the Borrowing Base in connection with, and simultaneously with, the consummation of an Asset Disposition described in the proviso of Section 9.5(b), and reduce the Borrowing Base by an amount equal to the Borrowing Base value of the Borrowing Base Properties that are the subject of such Asset Disposition (which shall be the Borrowing Base value assigned thereto by Lender). In the event Lender elects to redetermine the Borrowing Base in accordance with this Section 4.4, Lender shall notify Borrower promptly, but in any event no less than 1 Domestic Business Day prior to the consummation of the Asset Disposition, of the amount of the Borrowing Base as redetermined, which Borrowing Base shall be effective as of the date specified in such notice, and shall remain in effect for all purposes of this Agreement until the next Redetermination. Notwithstanding anything to the contrary contained herein, Borrower agrees that any such Redetermination pursuant to this Section 4.4 shall not be construed or deemed to be a Special Redetermination hereunder.

Section 4.5 Borrowing Base Deficiency. To the extent a Borrowing Base Deficiency exists after giving effect to any Redetermination (other than in connection with a Redetermination pursuant to Section 4.4), Borrower shall, within 5 days following notice thereof from Lender, provide written notice (the “Election Notice”) to Lender stating the action which Borrower proposes to take to remedy such Borrowing Base Deficiency, and Borrower shall thereafter, at its option, either (a) within 20 days following the delivery of the Election Notice, make a prepayment or prepayments of principal on the Revolving Loan in an amount sufficient to eliminate such Borrowing Base Deficiency, (b) eliminate such Borrowing Base Deficiency by making 6 consecutive mandatory prepayments of principal on the Revolving Loan, each of which shall be in the amount of 1/6th of the amount of such Borrowing Base Deficiency, commencing on the first Monthly Date following the delivery of the Election Notice, and continuing on each Monthly Date thereafter, or (c) within 20 days following the delivery of the Election Notice, submit (and pledge as collateral pursuant to Article V) additional oil and gas properties owned by Borrower and its Subsidiaries for consideration in connection with the determination of the Borrowing Base which Lender deems sufficient in its sole discretion to eliminate such Borrowing Base Deficiency. Notwithstanding the foregoing, upon any Redetermination of the Borrowing Base pursuant to Section 4.4 which results in a Borrowing Base Deficiency (or increase in an existing Borrowing Base Deficiency), Borrower shall immediately make a mandatory prepayment of principal on the Revolving Loan in an amount sufficient to eliminate such Borrowing Base Deficiency. In addition to the foregoing, until the Borrowing Base Deficiency is eliminated, the Applicable Margin on the Revolving Loan shall be increased by 2.0%.

Section 4.6 Borrowing Base Increase Fee. On the date of any Redetermination of the Borrowing Base pursuant to Section 4.2 or Section 4.3 that increases the Borrowing Base, Borrower shall pay to Lender, a Borrowing Base increase fee equal to 0.50% of the amount of the increase to the Borrowing Base.

Section 4.7 Initial Borrowing Base. Notwithstanding anything to the contrary contained herein, the Borrowing Base in effect during the period commencing on the Closing Date and ending on the effective date of the first Redetermination after the Closing Date shall be the Initial Borrowing Base.

(j) (i) any event occurs with respect to any Plan or Plans pursuant to which any Credit Party incurs a liability due and owing at the time of such event, without existing funding therefor, for benefit payments under such Plan or Plans; or (ii) any Credit Party, any ERISA Affiliate, or any other “party-in-interest” or “disqualified person,” as such terms are defined in section 3(14) of ERISA and section 4975(e)(2) of the Code, shall engage in transactions which in the aggregate result in a direct or indirect liability to any Credit Party or any ERISA Affiliate under section 409 or 502 of ERISA or section 4975 of the Code which either (A) results in a Lien on any Credit Party’s assets which is not a Permitted Encumbrance, or (B) continues unsatisfied for a period of thirty (30) days after any Authorized Officer of any Credit Party first acquires knowledge of such liability;

(k) a Change of Control shall occur;

(l) this Agreement or any other Loan Document shall cease to be in full force and effect or shall be declared null and void or the validity or enforceability thereof shall be contested or challenged by any Credit Party, or any Credit Party shall deny that it has any further liability or obligation under any of the Loan Documents, or any Lien created by the Loan Documents shall for any reason (other than the release thereof in accordance with the Loan Documents) cease to be a valid, first priority, perfected Lien (subject to Permitted Encumbrances) upon any of the Proved Mineral Interests purported to be covered thereby, except as a result of any action or inaction of Lender; or

ARTICLE XII

CHANGE IN CIRCUMSTANCES

Section 12.1 Increased Cost and Reduced Return.

(a) If, after the date hereof, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by Lender (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank, or comparable agency:

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

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

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

and the result of any of the foregoing is to increase the cost to Lender (or its Applicable Lending Office) of making, Converting into, Continuing, or maintaining any Eurodollar Loans or to reduce any sum received or receivable by Lender (or its Applicable Lending Office) under this Agreement or the Note with respect to any Eurodollar Loans, then the Borrower shall pay to Lender on demand such amount or amounts as will compensate Lender for such increased costs or reductions incurred or experienced within 90 days of such demand. If Lender requests compensation by Borrower under this Section 12.1(a), the Borrower may, by notice to Lender, suspend the obligation of Lender to make or Continue Eurodollar Loans or to Convert all or part of the Base Rate Loan owing to Lender into Eurodollar Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 12.4 shall be applicable); provided, that such suspension shall not affect the right of Lender to receive the compensation so requested.

(b) If, after the date hereof, Lender shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of Lender or any corporation controlling Lender as a consequence of Lender’s obligations hereunder to a level below that which Lender or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then, from time to time upon demand, Borrower shall pay to Lender such additional amount or amounts as will compensate Lender for such reductions experienced within 90 days of such demand.

(c) Lender shall promptly notify Borrower of any event of which it has knowledge, occurring after the date hereof, that will entitle Lender to compensation pursuant to this Section 12.1 and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of Lender, be otherwise disadvantageous to it. Lender claiming compensation under this Section 12.1 shall furnish to Borrower a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, Lender may use any reasonable averaging and attribution methods.

Section 12.2 Limitation on Type of Loans. If on or prior to the first day of any Interest Period for any Eurodollar Loan:

(a) Lender determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period; or

(b) Lender determines (which determination shall be conclusive) that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to Lender of funding Eurodollar Loans for such Interest Period;

then Lender shall give Borrower prompt notice thereof specifying the relevant Type of Revolving Loans and the relevant amounts or periods, and so long as such condition remains in effect, Lender shall be under no obligation to make additional Revolving Loans of such Type, Continue Revolving Loans of such Type, or to Convert Revolving Loans of any other Type into Revolving Loans of such Type, and Borrower shall, on the last day(s) of the then current Interest Period(s) for the outstanding Revolving Loans of the affected Type, either prepay such Revolving Loans or Convert such Revolving Loans into another Type of Revolving Loan in accordance with the terms of this Agreement.

Section 12.3 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for Lender or its Applicable Lending Office to make, maintain, or fund Eurodollar Loans hereunder, then Lender shall promptly notify Borrower thereof and Lender’s obligation to make or Continue Eurodollar Loans and to Convert other Types of Revolving Loans into Eurodollar Loans shall be suspended until such time as Lender may again make, maintain, and fund Eurodollar Loans (in which case the provisions of Section 12.4 shall be applicable).

Section 12.4 Treatment of Affected Loans. If the obligation of Lender to make particular Eurodollar Loans or to Continue Revolving Loans, or to Convert Revolving Loans of another Type into Revolving Loans of a particular Type shall be suspended pursuant to Section 12.1 or Section 12.3 (Revolving Loans of such Type being herein called “Affected Loans” and such Type being herein called the “Affected Type”), Lender’s Affected Loans shall be automatically Converted into the Base Rate Loan on the last day(s) of the then current Interest Period(s) for Affected Loans (or, in the case of a Conversion required by Section 12.3, on such earlier date as Lender may specify to Borrower) and, unless and until Lender gives notice as provided below that the circumstances specified in Section 12.1 or Section 12.3 that gave rise to such Conversion no longer exist:

(a) to the extent that Lender’s Affected Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to Lender’s Affected Loans shall be applied instead to the Base Rate Loan; and

(b) all Revolving Loans that would otherwise be made or Continued by Lender as Revolving Loans of the Affected Type shall be made or Continued instead as part of the Base Rate Loan, and all Revolving Loans of Lender that would otherwise be Converted into Revolving Loans of the Affected Type shall be Converted instead into (or shall remain) as part of the Base Rate Loan.

Section 12.5 Compensation. Upon the request of Lender, Borrower shall pay to Lender such amount or amounts as shall be sufficient (in the reasonable opinion of Lender) to compensate it for any loss, cost, or expense (including loss of anticipated profits) incurred by it as a result of:

(a) any payment, prepayment, or Conversion of a Eurodollar Loan for any reason (including, without limitation, the acceleration of the Revolving Loan) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by the Borrower for any reason (including, without limitation, the failure of any condition precedent specified in Article VI to be satisfied) to borrow, Convert, Continue, or prepay a Eurodollar Loan on the date for such Borrowing, Conversion, Continuation, or prepayment specified in the relevant Request for Borrowing, Notice of Continuation or Conversion, or other notice of Borrowing, prepayment, Continuation, or Conversion under this Agreement.

Section 12.6 Taxes.

(a) Any and all payments by Borrower to or for the account of Lender hereunder or under any other Loan Document shall be made free and clear of and without deduction for any and all present or future Taxes, duties, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of Lender, Taxes imposed on its income, and franchise Taxes imposed on it (all such non-excluded Taxes, duties, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to in this Section 12.6 as “Non-Excluded Taxes”). If Borrower shall be required by Law to deduct any Non-Excluded Taxes from or with respect to any sum payable under this Agreement or any other Loan Document to Lender, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 12.6) Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Law, and (iv) Borrower shall furnish to Lender, at its address set forth on the signature pages below hereto, the original or a certified copy of a receipt evidencing payment thereof.

(b) In addition, Borrower agrees to pay any and all present or future stamp or documentary Taxes and any other excise or property Taxes or charges or similar levies which arise from any payment made under this Agreement or any other Loan Document or from the execution or delivery of, or otherwise with respect to, this Agreement or any other Loan Document (“Other Taxes”).

(c) Borrower agrees to indemnify Lender for the full amount of Non-Excluded Taxes and Other Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 12.6) paid by Lender and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto.

(d) If Lender is organized under the Laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement, and from time to time thereafter if requested in writing by Borrower (but only so long as Lender remains lawfully able to do so), shall provide Borrower, at the time or times prescribed by applicable Law, with such properly completed and executed documentation prescribed by applicable Law (or reasonably requested by Borrower) certifying that Lender is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, and certifying that Lender is entitled to an exemption from or a reduced rate of tax on payments pursuant to this Agreement or any of the other Loan Documents.

(e) For any period with respect to which Lender has failed to provide Borrower with the appropriate form pursuant to Section 12.6(d) (unless such failure is due to a change in treaty, law, or regulation occurring subsequent to the date on which a form originally was required to be provided), Lender shall not be entitled to indemnification under Section 12.6(a), Section 12.6(b) or Section 12.6(c) with respect to Non-Excluded Taxes imposed by the United States; provided, however, that if Lender is exempt from or subject to a reduced rate of withholding Tax, and becomes subject to Non-Excluded Taxes because of its failure to deliver a form required hereunder, Borrower shall take such steps as Lender shall reasonably request to assist Lender to recover such Non-Excluded Taxes.

(f) If Borrower is required to pay additional amounts to or for the account of Lender pursuant to this Section 12.6, then Lender will agree to use reasonable efforts to change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment that may thereafter accrue if such change, in the judgment of Lender, is not otherwise disadvantageous to Lender.

(g) Within 30 days after the date of any payment of Non-Excluded Taxes, Borrower shall furnish to Lender the original or a certified copy of a receipt evidencing such payment.

(h) Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 12.6 shall survive the termination of the Commitment and the payment in full of the Revolving Loans.

Section 12.7 Discretion of Lender as to Manner of Funding. Notwithstanding any provisions of this Agreement to the contrary, Lender shall be entitled to fund and maintain its funding of all or any part of the Commitment in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if Lender had actually funded and maintained each Eurodollar Loan during the Interest Period for such Eurodollar Loan through the purchase of deposits having a maturity corresponding to the last day of such Interest Period and bearing an interest rate equal to the Adjusted Eurodollar Rate for such Interest Period.

Section 13.2 No Waivers. No failure or delay by Lender in exercising any right, power or privilege hereunder or under any other Loan Document shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Law or in any of the other Loan Documents.

Section 13.3 Expenses; Indemnification.

(a) Borrower agrees to pay on demand all reasonable costs and expenses of Lender in connection with the preparation, execution, delivery, modification, and amendment of this Agreement, the other Loan Documents, and the other documents to be delivered hereunder, including, without limitation, the reasonable fees and expenses of counsel for Lender with respect thereto and with respect to advising Lender as to its rights and responsibilities under the Loan Documents. Borrower further agrees to pay on demand all costs and expenses of Lender, if any (including, without limitation, reasonable attorneys’ fees and expenses), in connection with (i) the enforcement (whether through negotiations, legal proceedings, or otherwise) of the Loan Documents and the other documents to be delivered hereunder, and (ii) any forbearance or workout, or any modifications to the Loan Documents, following an Event of Default. Each demand for payment of costs and expenses shall include a reasonably detailed list of such costs and expenses, and such costs and expenses payable hereunder shall not include the allocated costs of internal counsel of any Agent or Lender.

(b) BORROWER AGREES TO INDEMNIFY AND HOLD HARMLESS LENDER AND ITS AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND ADVISORS (EACH, AN “INDEMNIFIED PARTY”) FROM AND AGAINST ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS, AND EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS’ FEES) THAT MAY BE INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE ARISING OUT OF OR IN CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN CONNECTION THEREWITH) THE LOAN DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE REVOLVING LOAN (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH INDEMNIFIED PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. IN THE CASE OF AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE INDEMNITY IN THIS SECTION 13.3 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY CREDIT PARTIES, ITS DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN INDEMNIFIED PARTY OR ANY OTHER PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. BORROWER AGREES NOT TO ASSERT ANY CLAIM AGAINST ANY AGENT, LENDER, ANY OF THEIR AFFILIATES, OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS, AGENTS, AND ADVISERS, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE LOAN DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE REVOLVING LOAN.

(c) Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 13.3 shall survive the payment in full of the Revolving Loan and all other amounts payable under this Agreement.

Section 13.4 Right of Set-off. Upon the occurrence and during the continuance of any Event of Default, Lender (and each of its Affiliates) is hereby authorized at any time and from time to time, to the fullest extent permitted by Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by Lender (or any of its Affiliates) to or for the credit or the account of any Credit Party against any and all of the Obligations, irrespective of whether Lender shall have made any demand under this Agreement or the Note held by such and although such obligations may be unmatured. Lender agrees promptly to notify the affected Credit Party after any such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of Lender under this Section 13.4 are in addition to other rights and remedies (including, without limitation, other rights of set-off) that Lender may have.

Section 13.5 Amendments and Waivers. Any provision of this Agreement or any other Loan Document may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by Borrower and Lender.

Section 13.6 Survival. All representations, warranties and covenants made by any Credit Party herein or in any certificate or other instrument delivered by it or in its behalf under the Loan Documents shall be considered to have been relied upon by Lender and shall survive the delivery to Lender of such Loan Documents or the extension of the Revolving Loan (or any part thereof), regardless of any investigation made by or on behalf of Lender. The indemnity provided in Section 13.3(c) herein shall survive the repayment of all credit advances hereunder and the discharge or release of any Lien granted hereunder or in any other Loan Document, contract or agreement between Borrower or any other Credit Party and Lender.

Section 13.7 Limitation on Interest. Regardless of any provision contained in the Loan Documents, Lender shall never be entitled to receive, collect, or apply, as interest on the Revolving Loan, any amount in excess of the Maximum Lawful Rate, and in the event Lender ever receives, collects or applies as interest any such excess, such amount which would be deemed excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such; and if the Revolving Loan is paid in full, any remaining excess shall promptly be paid to Borrower. In determining whether or not the interest paid or payable under any specific contingency exceeds the Maximum Lawful Rate, Borrower and Lender shall, to the extent permitted under applicable Law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate and spread, in equal parts, the total amount of the interest throughout the entire contemplated term of the Revolving Loans, so that the interest rate is the Maximum Lawful Rate throughout the entire term of the Revolving Loans; provided, however, that if the unpaid principal balance thereof is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Lawful Rate, Lender shall refund to Borrower the amount of such excess and, in such event, Lender shall not be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Lawful Rate.

Section 13.8 Invalid Provisions. If any provision of the Loan Documents is held to be illegal, invalid, or unenforceable under present or future Laws effective during the term thereof, such provision shall be fully severable, the Loan Documents shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part thereof, and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as a part of the Loan Documents a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and enforceable.

Section 13.9 Assignments and Participations.

(a) Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of Borrower and Lender and their respective successors and assigns permitted hereby, except that (i) Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of Lender, (ii) any assignment by Lender must be made in compliance with Section 13.9(c), and (iii) any transfer by participation must be made in compliance with Section 13.9(b). Any attempted assignment or transfer by any party not made in compliance with this Section 13.9(a) shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 13.9(b). The parties to this Agreement acknowledge that clause (ii) of this Section 13.9(a) relates only to absolute assignments and this Section 13.9(a) does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by Lender of all or any portion of its rights under this Agreement and Note to a Federal Reserve Lender or (y) if Lender is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and the Note to its trustee in support of its obligations to its trustee; provided, however, that no such pledge or assignment creating a security interest shall release Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 13.9(c). Any assignee of the rights to any Revolving Loan or the Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Revolving Loan, shall be conclusive and binding on any subsequent holder or assignee of the rights to such Revolving Loan.

(b) Participations.

(i) Lender may at any time sell to one or more banks or other entities (“Participants”) participating interests in any Revolving Loan owing to Lender, the Note, any Commitment of Lender or any other interest of Lender under the Loan Documents. In the event of any such sale by Lender of participating interests to a Participant, Lender’s obligations under the Loan Documents shall remain unchanged, Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, Lender shall remain the owner of its Revolving Loans and the holder of the Note, all amounts payable by Borrower under this Agreement shall be determined as if Lender had not sold such participating interests, and Borrower shall continue to deal solely and directly with Lender in connection with Lender’s rights and obligations under the Loan Documents.

(ii) Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents.

(iii) Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 13.4 with respect to 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 if were the Lender under the Loan Documents; provided, that Lender shall retain the right of setoff provided in Section 13.4 with respect to the amount of participating interests sold to each Participant. Lender agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 13.4, agrees to share with Lender, any amount received pursuant to the exercise of its right of setoff. If Lender or any Participant shall at any time receive any payment of all or part of the amounts owing to it, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, or otherwise), in a greater proportion than any such payment to or received by Lender or any other Participant, if any, with respect to Lender’s or such other Participant’s amounts owing to it, or interest thereon, Lender or such Participant shall purchase for cash from Lender and the other Participants, as appropriate, a participating interest in such portion of Lender’s or each such other Participant’s amounts owing to it, or shall provide Lender or such other Participants, as applicable, with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause the Lender or such Participant to share the excess payment or benefits of such collateral or proceeds ratably with Lender and each other Participant; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from Lender or such Participant, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Borrower agrees that any Participant so purchasing a participation from a Lender pursuant to this Section 13.9 may, to the fullest extent permitted by Law, exercise all of its rights of payment (including the right of set-off) with respect to such participation as fully as if such Participant were the direct creditor of Borrower in the amount of such participation.

(iv) Borrower further agrees that each Participant shall be entitled to the yield protection provisions contained in Article XII to the same extent as if it were the Lender and had acquired its interest by assignment pursuant to Section 13.9(c); provided, that (A) a Participant shall not be entitled to receive any greater payment under Article XII than that attributable to the participating interest sold to such Participant would have received had Lender retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of Borrower, and (B) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 12.6 to the same extent as if it were a Lender.

(i) Lender may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Loan Documents. The parties to such assignment shall execute and deliver an assignment and acceptance agreement in such other form as may be agreed to by the parties thereto (“Assignment and Acceptance Agreement”). Each such assignment with respect to a Purchaser which is not an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Revolving Loans of Lender or (unless each of Borrower otherwise consents) be in an aggregate amount not less than $100,000. The amount of the assignment shall be based on the Commitment or outstanding Revolving Loans (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Effective Date,” if the “Effective Date” is specified in the Assignment and Acceptance Agreement.

(ii) The consent of Borrower shall be required prior to an assignment becoming effective unless Purchaser is an Affiliate of a Lender or an Approved Fund, provided that the consent of Borrower shall not be required if a Default has occurred and is continuing. Any consent required under this Section 13.9(c)(ii) shall not be unreasonably withheld or delayed.

(iii) Such assignment shall become effective on the effective date specified in such Assignment and Acceptance Agreement. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of Lender and shall have all the rights and obligations of Lender under the Loan Documents proportionate to its Commitment, to the same extent as if it were an original party thereto, and Lender shall be released with respect to the Commitment and Revolving Loans assigned to such Purchaser without any further consent or action by Borrower or Lender. In the case of an assignment covering all of the assigning Lender’s rights and obligations under this Agreement, Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents that survive payment of the Obligations and termination of the applicable agreement. Any assignment or transfer by Lender of rights or obligations under this Agreement that does not comply with this Section 13.9(c) shall be treated for purposes of this Agreement as a sale by Lender of a participation in such rights and obligations in accordance with Section 13.9(b). Upon the consummation of any assignment to a Purchaser pursuant to this Section 13.9(c), Lender and Borrower shall make appropriate arrangements so that (as applicable) a new Note or, as appropriate, a replacement Note is issued to Lender and (as applicable) a new Note is issued to the Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

(d) Dissemination of Information. Borrower authorizes Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (“Transferee”) and any prospective Transferee any and all information in Lender’s possession concerning the creditworthiness of Borrower and its Subsidiaries, including, without limitation, any information contained in any financial reports; provided, that, each Transferee and prospective Transferee agrees to be bound by Section 13.16 of this Agreement.

(e) Tax Treatment. If any interest in any Loan Document is transferred to any Transferee that is not incorporated under the laws of the United States or any State thereof, Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 12.6(d).

Section 13.10 COLORADO LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF COLORADO AND THE LAWS OF THE UNITED STATES OF AMERICA, EXCEPT TO THE EXTENT THAT THE LAWS OF ANY STATE IN WHICH ANY PROPERTY INTENDED AS SECURITY FOR THE OBLIGATIONS IS LOCATED NECESSARILY GOVERN (A) THE PERFECTION AND PRIORITY OF THE LIENS IN FAVOR OF LENDER WITH RESPECT TO SUCH PROPERTY, AND (B) THE EXERCISE OF ANY REMEDIES (INCLUDING FORECLOSURE) WITH RESPECT TO SUCH PROPERTY.

Section 13.11 Consent to Jurisdiction; Waiver of Immunities.

(a) Borrower hereby irrevocably submits to the jurisdiction of any Colorado State or Federal court sitting in the District of Colorado over any action or proceeding arising out of or relating to this Agreement or any other Loan Documents, and Borrower hereby irrevocably agrees that all claims with respect to such action or proceeding may be heard and determined in such Colorado State or Federal court.
