TERMS OF FACILITY

2.1
Revolving Line of Credit. (a) Upon the terms and conditions (including, without limitation, the right of any Lender to decline to make any Loan so long as any Default or Event of Default exists) and relying on the representations and
warranties contained in this Agreement, each Lender severally agrees, during the Commitment Period, to make Loans, in immediately available funds at the Applicable Lending Office or the Principal Office, to or for the benefit of the Borrower in an
amount not to exceed at any time outstanding the lesser of the Borrowing Base or the Percentage Share of such Lender of the Borrowing Base then in effect. Loans shall be made from time to time on any Business Day designated by the Borrower following
receipt by the Agent of a Borrowing Request.

(b) Subject to the terms of this Agreement, during the Commitment Period, the Borrower may

prepayment of principal of Loans shall be in an amount at least equal to $100,000. Each borrowing, prepayment, or conversion of or into a Loan of a different type or, in the case of a LIBO Rate Loan, having a different Interest Period, shall be
deemed a separate borrowing, conversion, and prepayment for purposes of the foregoing, one for each type of Loan or Interest Period. Anything in this Agreement to the contrary notwithstanding, the aggregate principal amount of LIBO Rate Loans having
the same Interest Period shall be at least equal to $100,000; and if any LIBO Rate Loan would otherwise be in a lesser principal amount for any period, such Loan shall be a Floating Rate Loan during such period.

(c) The Loans shall be made and maintained at the Applicable Lending Office or the Principal Office and shall be evidenced by the Notes.

(d) Not later than 2:00 p.m., Central Standard or Central Daylight Savings Time, as the case may be, on the date specified for each borrowing, the
Lenders shall make available to the Agent, in immediately available funds, the proceeds of borrowings requested by Borrower for the account of the Borrower. The amount so received by the Agent shall, subject to the terms and conditions hereof, be
made available to the Borrower in immediately available funds at the Principal Office by the end of that Business Day. All Loans by the Lenders shall be maintained at the Applicable Lending Office of the Lenders and shall be evidenced by the Note of

2.2 Letter of Credit Facility. (a) Upon the terms and conditions and relying on the
representations and warranties contained in this Agreement, the Agent, as issuing bank for the Lenders, agrees from the date of this Agreement until the date which is thirty days prior to the Commitment Termination Date, to issue on behalf of the
Lenders in their respective Percentage Shares, Letters of Credit for the account of the Borrower and to renew and extend such Letters of Credit. Letters of Credit shall be issued, renewed, or extended from time to time on any Business Day designated
by the Borrower following the receipt in accordance with the terms hereof by the Agent of the written (or oral, confirmed promptly in writing) request by a Responsible Officer of the Borrower and a Letter of Credit Application. Letters of Credit
shall be issued in such amounts as the Borrower may request; provided, however, that (i) no Letter of Credit shall have an expiration date which is more than 365 days after the issuance thereof or subsequent to Final Maturity, (ii) each
automatically renewable Letter of Credit shall provide that it may be terminated by the Agent at its then current expiry date by not less than 30 days written notice by the Agent to the beneficiary of such Letter of Credit, and (iii) the
Agent shall not be obligated to issue any Letter of Credit if (A) the face amount thereof would exceed the Available Commitment, or (B) after giving effect to the issuance thereof, the L/C Exposure, when added to the Loan Balance then
outstanding, would exceed the Borrowing Base, or (C) the L/C Exposure would exceed $2,000,000, and (iv) notwithstanding the above, Letters of Credit may be issued for Commodity Hedge Agreements or Rate Management Transactions at the sole
discretion of the Agent up to an amount not to exceed $5,000,000 as evidenced by the Note shown on Exhibit I(A). Any Letters of Credit issued under (iv) above shall be cross-collateralized and cross-defaulted with the other Obligations
hereunder and if drawn shall be due on demand.

(b) Prior to any payment in respect of any Letter of Credit, each Lender shall be deemed to
be a participant through the Agent with respect to the relevant Letter of Credit in the obligation of the Agent, as the issuer of such Letter of Credit, in an amount equal to the Percentage Share of such Lender of the maximum amount which is or at
any time may become available to be drawn thereunder. Upon delivery by such Lender of funds requested pursuant to Section 2.2(c), such Lender shall be treated as having purchased a participating interest in an amount equal to such funds
delivered by such Lender to the Agent in the obligation of the Borrower to reimburse the Agent, as the issuer of such Letter of Credit, for any amounts payable, paid, or incurred by the Agent, as the issuer of such Letter of Credit, with respect to
such Letter of Credit.

(c) Each Lender shall be unconditionally and irrevocably liable, without regard to the occurrence of any Default or
Event of Default, to the extent of the Percentage Share of such Lender at the time of issuance of each Letter of Credit, to reimburse, on demand, the Agent, as the issuer of such Letter of Credit, for the amount of each Letter of Credit Payment
under such Letter of Credit. Each payment in respect of any Letter of Credit shall be deemed to be a Floating Rate Loan by each Lender to the extent of funds delivered by such Lender to the Agent with respect to such payment and shall to such extent
be deemed a Floating Rate Loan under and shall be evidenced by the Note of such Lender.

(d) EACH LENDER
AGREES TO SEVERALLY INDEMNIFY THE AGENT, AS THE ISSUER OF EACH LETTER
OF CREDIT, AND THE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,

ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE GROSS
NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OR WILLFUL MISCONDUCT OF THE AGENT

limited liability company purposes and to support Commodity Hedge Agreements and Rate Management Transactions.

2.4 Interest.
Subject to the terms of this Agreement (including, without limitation, Section 2.17), interest on the Loans shall accrue and be payable at a rate per annum equal to the Floating Rate for each Floating Rate Loan and the Adjusted LIBO Rate for
each LIBO Rate Loan. Interest on all Floating Rate Loans shall be computed on the basis of a year of 365 or 366 days, as applicable, for the actual days elapsed (including the first day but excluding the last day) during the period for which
payable. Interest on all LIBO Rate Loans shall be computed on the basis of a year of 360 days for the actual days elapsed (including the first day but excluding the last day) during the period for which payable. Notwithstanding the foregoing,
interest on past-due principal and, to the extent permitted by applicable law, past-due interest, shall accrue at the Default Rate, computed on the basis of a year of 365 or 366 days, as the case may be, for



- 19 -



---

the actual days elapsed (including the first day but excluding the last day) during the period for which payable, and shall be payable by the Borrower upon
demand by the Agent at any time as to all or any portion of such interest. In the event that the Borrower fails to select the duration of any Interest Period for any LIBO Rate Loan within the time period and otherwise as provided herein, such Loan
(if outstanding as a LIBO Rate Loan) will be automatically converted into a Floating Rate Loan on the last day of the then current Interest Period for such Loan or (if outstanding as a Floating Rate Loan) will remain as, or (if not then outstanding)
will be made as, a Floating Rate Loan. Interest provided for herein shall be calculated on unpaid sums actually advanced and outstanding pursuant to the terms of this Agreement and only for the period from the date or dates of such advances until
repayment.

2.5 Repayment of Loans and Interest. Accrued and unpaid interest on each outstanding Floating Rate Loan shall be due and
payable monthly commencing on the first day of April, 2008 and continuing on the first day of each calendar month thereafter while any Floating Rate Loan remains outstanding, the payment in each instance to be the amount of interest which has
accrued and remains unpaid in respect of the relevant Loan. Accrued and unpaid interest on each outstanding LIBO Rate Loan shall be due and payable on the last day of the Interest Period for such LIBO Rate Loan corresponding to the day of the
calendar month on which such Interest Period commenced, the payment in each instance to be the amount of interest which has accrued and remains unpaid in respect of the relevant Loan. The Loan Balance, together with all accrued and unpaid interest
thereon, shall be due and payable at Final Maturity. At the time of making each payment hereunder or under the Notes, the Borrower shall specify to the Agent the Loans or other amounts payable by the Borrower hereunder to which such payment is to be
applied. In the event the Borrower fails to so specify, or if an Event of Default has occurred and is continuing, the Agent may apply such payment as it may elect in its sole discretion.

2.6 Outstanding Amounts. The outstanding principal balance of the Notes reflected by the notations by the Agent and the Lenders on their records
shall be deemed rebuttably presumptive evidence of the principal amount owing on the Notes. The liability for payment of principal and interest evidenced by the Notes shall be limited to principal amounts actually advanced and outstanding pursuant
to this Agreement and interest on such amounts calculated in accordance with this Agreement.

2.7 Time, Place, and Method of
Payments. All payments required pursuant to this Agreement or the Notes shall be made in lawful money of the United States of America and in immediately available funds, shall be deemed received by the Agent on the Business Day received, or on
the next Business Day following receipt if such receipt is after 2:00 p.m., Central Standard or Central Daylight Savings Time, as the case may be, on any Business Day, and shall be made at the Principal Office. Except as provided to the contrary
herein, if the due date of any payment hereunder or under the Notes would otherwise fall on a day which is not a Business Day, such date shall be extended to the next succeeding Business Day, and interest shall be payable for any principal so
extended for the period of such extension.

2.8 Pro Rata Treatment; Adjustments. (a) Except to the extent otherwise expressly
provided herein, (i) each borrowing pursuant to this Agreement shall be made from the Lenders pro rata in accordance with their respective Percentage Shares, (ii) each reduction of the sum of



- 20 -



---

the Facility Amounts of the Lenders at the request of the Borrower, as well as any subsequent increase in the sum of the Facility Amounts of the Lenders at
the request of the Borrower and with written agreement of the Agent and the Required Lenders, shall serve to adjust the Facility Amounts of the Lenders pro rata in accordance with the Facility Amounts of the Lenders in effect immediately prior to
any such adjustment, (iii) each payment by the Borrower of fees shall be made for the account of the Lenders pro rata in accordance with their respective Percentage Shares, (iv) each payment of principal of Loans shall be made for the
account of the Lenders pro rata in accordance with their Percentage Shares of the Loan Balance, and (v) each payment of interest on Loans shall be made for the account of the Lenders pro rata in accordance with their Percentage Shares of the
aggregate amount of interest due and payable to the Lenders.

(b) The Agent shall distribute all payments with respect to the Obligations
to the Lenders promptly upon receipt in like funds as received. In the event that any payments made hereunder by the Borrower at any particular time are insufficient to satisfy in full the Obligations due and payable at such time, such payments
shall be applied (i) first, to fees and expenses due pursuant to the terms of this Agreement or any other Loan Document, (ii) second, to accrued interest, (iii) third, to the Loan Balance, and (iv) last, to any other Obligations.

(c) If any Lender (for purposes of this Section, a Benefitted Lender) shall at any time receive any payment of all or
part of its portion of the Obligations, or receive any Collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 7.1(f) or
Section 7.1(g), or otherwise) in an amount greater than such Lender was entitled to receive pursuant to the terms hereof, such Benefitted Lender shall purchase for cash from the other Lenders such portion of the Obligations of such other
Lenders, or shall provide such other Lenders with the benefits of any such Collateral or the proceeds thereof, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such Collateral or proceeds with each of
the Lenders according to the terms hereof. If all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded and the purchase price and benefits returned by such Lender, to
the extent of such recovery, but without interest. The Borrower agrees that each such Lender so purchasing a portion of the Obligations of another Lender may exercise all rights of payment (including rights of set-off) with respect to such portion
as fully as if such Lender were the direct holder of such portion. If any Lender ever receives, by voluntary payment, exercise of rights of set-off or bankers lien, counterclaim, cross-action or otherwise, any funds of the Borrower to be
applied to the Obligations, or receives any proceeds by realization on or with respect to any Collateral, all such funds and proceeds shall be forwarded immediately to the Agent for distribution in accordance with the terms of this Agreement.

2.9 Borrowing Base Determinations. (a) The Borrowing Base as of the Closing Date is acknowledged by the Borrower, the Agent
and the Lenders to be $32,400,000. Commencing on May 10, 2008 and continuing thereafter on the tenth day of each calendar month through the Commitment Termination Date, the amount of the Borrowing Base shall be reduced by the Monthly Commitment
Reduction Amount, which Monthly Commitment Reduction Amount as of the Closing Date is acknowledged by the Borrower and the Agent to be $1,500,000.



- 21 -



---

(b) The Borrowing Base and the Monthly Commitment Reduction Amount shall be redetermined by the Agent on
October 1, 2008 and thereafter semi-annually (on each April 1 and October 1 prior to the Commitment Termination Date) on the basis of information supplied by the Borrower in compliance with the provisions of this Agreement, including
Reserve Reports, and all other relevant information available to the Agent and the Lenders. In addition, the Agent shall, in the normal course of business following a request of the Borrower, redetermine the Borrowing Base and the Monthly Commitment
Reduction Amount; provided, however, the Agent shall not be obligated to respond to more than two such requests in any calendar year. The Borrower may make additional requests for which agreement will not be unreasonably withheld by the Agent.
Notwithstanding the foregoing, the Agent may at its discretion redetermine the Borrowing Base and the Monthly Commitment Reduction Amount at any time and from time to time.

(c) Upon each determination of the Borrowing Base and the Monthly Commitment Reduction Amount, the Agent shall notify the Borrower orally (confirming
such notice promptly in writing) of such determinations, and the amounts so communicated to the Borrower shall become effective upon such oral notification and shall remain in effect until the next subsequent determination of such amounts.

(d) The Borrowing Base shall represent the determination by the Lenders, in accordance with the applicable definitions and provisions
herein contained and their customary lending practices for loans of this nature, of the value, for loan purposes, of the Mortgaged Properties, subject, in the case of any increase in the Borrowing Base, to the credit approval process of the Lenders.
Furthermore, the Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is acknowledged by the Borrower to be essential for the adequate protection of the Lenders.

(e) Notwithstanding any other provision of this Section 2.9, the Borrower shall be entitled, by written request of the Borrower to
the Agent at any time (any such request being irrevocable, absent written agreement of the Agent and the Required Lenders with respect to any subsequently requested increase in the Borrowing Base, which written agreement may be expressly conditioned
on the payment of a fee by the Borrower to the Agent, for the account of the Lenders) to a reduction in the Borrowing Base.

2.10
Mandatory Prepayments. If at any time the Loan Balance and the L/C Exposure exceeds the Borrowing Base then in effect and exceeds the Borrowing Base, the Borrower shall, within 5 Business Days of notice from the Agent of such occurrence,
(a) prepay, or make arrangements acceptable to the Agent for the prepayment of, the amount of such excess for application on the Loan Balance, (b) provide additional collateral, of character and value satisfactory to the Agent in its
reasonable discretion, to secure the Obligations by the execution and delivery to the Agent of security instruments in form and substance satisfactory to the Agent in the exercise of its reasonable discretion, or (c) effect any combination of
the alternatives described in clauses (a) and (b) of this Section and acceptable to the Agent in its reasonable discretion. In the event that a mandatory prepayment is required under this Section and the amount owed on the Notes plus
accrued interest is less than the amount required to be prepaid, the Borrower shall repay the amount owed, plus accrued interest and, in accordance with the provisions of the relevant Letter of Credit Applications executed by the Borrower or
otherwise to



- 22 -



---

the reasonable satisfaction of the Agent, deposit with the Agent, as additional collateral securing the Obligations, an amount of cash, in immediately
available funds, equal to the L/C Exposure minus the Borrowing Base. The cash deposited with the Agent in satisfaction of the requirement provided in this Section may be invested, at the reasonable discretion of the Agent and then only at the
express direction of the Borrower as to investment vehicle and maturity (which shall be no later than the latest expiry date of any then outstanding Letter of Credit), for the account of the Borrower in cash or cash equivalent investments offered by
or through the Agent.

2.11 Voluntary Prepayments and Conversions of Loans. Subject to applicable provisions of this Agreement, the
Borrower shall have the right at any time or from time to time to prepay Loans and to convert Loans of one type or with one Interest Period into Loans of another type or with a different Interest Period; provided, however, that (a) the Borrower
shall give the Agent notice of each such prepayment or conversion of all or any portion of a LIBO Rate Loan no less than two Business Days prior to prepayment or conversion, (b) any LIBO Rate Loan may be prepaid or converted only on the last
day of an Interest Period for such Loan, (c) the Borrower shall pay all accrued and unpaid interest on the amounts prepaid or converted, and (d) no such prepayment or conversion shall serve to postpone the repayment when due of any
Obligation.

2.12 Commitment Fee. In addition to interest on the Notes as provided herein and all other fees payable hereunder and
to compensate the Lenders for maintaining funds available, the Borrower shall pay to the Agent for the account of the Lenders, in immediately available funds, on the first day of April, 2008, and on the first day of each third calendar month
thereafter during the Commitment Period, a fee in the amount of 0.375% per annum, calculated on the basis of a year of 365 or 366 days, as the case may be, for the actual days elapsed (including the first day but excluding the last day), on the
average daily amount of the Available Commitment during the preceding quarterly period.

2.13 RESERVED.

2.14 Letter of Credit Fee. In addition to interest on the Notes as provided herein and all other fees payable hereunder, the Borrower agrees to
pay to the Agent for the account of the Lenders, on the date of issuance of each Letter of Credit, a fee equal to the greater of $500 or 2.00% calculated on the basis of a year of 365 or 366 days, as the case may be, for the actual days elapsed
(including the first day but excluding the last day), on the face amount of such Letter of Credit during the period for which such Letter of Credit is issued; provided, however, in the event such Letter of Credit is canceled prior to its original
expiry date or a payment is made by the Agent on behalf of the Lenders with respect to such Letter of Credit, the Agent shall, within 30 days after such cancellation or the making of such payment, rebate to the Borrower the unearned portion of such
fee. The Borrower also agrees to pay to Guaranty, on demand and solely for its account, its customary letter of credit transactional fees, including, without limitation, amendment fees, payable with respect to each Letter of Credit.

2.15 Loans to Satisfy Obligations of Borrower. The Lenders may, but shall not be obligated to, but only if an Event of Default exists, make Loans
for the benefit of the Borrower and apply proceeds thereof to the satisfaction of any condition, warranty, representation, or covenant of the Borrower contained in this Agreement or any other Loan Document. Any such Loan shall be evidenced by the
Notes and shall be made as a Floating Rate Loan.



- 23 -



---

2.16 Security Interest in Accounts; Right of Offset. As security for the payment and performance
of the Obligations, the Borrower hereby transfers, assigns, and pledges to the Agent for the benefit of the Lenders, and grants to the Agent for the benefit of the Lenders, a security interest in all funds of the Borrower now or hereafter or from
time to time on deposit with the Agent and such Lenders, with such interest to be retransferred, reassigned, and/or released by the Agent and each Lender, as the case may be, at the expense of the Borrower upon payment in full and complete
performance by the Borrower of all Obligations. All remedies as secured party or assignee of such funds shall be exercisable by the Agent during the existence of the occurrence of any Event of Default, regardless of whether the exercise of any such
remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof. Furthermore, the Borrower hereby grants to the Agent and each Lender the
right, exercisable during the existence of an Event of Default, of offset or bankers lien against all funds of the Borrower now or hereafter or from time to time on deposit with the Agent and each Lender, regardless of whether the exercise of
any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof, provided that such Obligation shall have matured, whether by
acceleration of maturity or otherwise.

2.17 General Provisions Relating to Interest. (a) It is the intention of the parties
hereto to comply strictly with the usury laws of the State of Texas and the United States of America. In this connection, there shall never be collected, charged, or received on the sums advanced hereunder interest in excess of that which would
accrue at the Highest Lawful Rate. The Borrower agrees that, to the extent the Highest Lawful Rate is determined with reference to the laws of the State to Texas, the Highest Lawful Rate shall be the weekly rate as defined in Chapter 303
of the Texas Finance Code (Vernons 1999), provided that the Lender may, at its election, substitute for the weekly rate the annualized or quarterly rate, as such terms are defined in the aforesaid
statute, upon the giving of notices provided for in such statute and effective upon the giving of such notices. The Lender may also rely, to the extent permitted by applicable laws of the State of Texas or the United States of America, on
alternative maximum rates of interest under other laws of the State of Texas or the United States of America applicable to the Lender, if greater.

(b) Notwithstanding anything herein or in the Notes, or any of them, to the contrary, during any Limitation Period, the interest rate to be charged on amounts evidenced by the Notes shall be the Highest Lawful Rate, and the obligation, if
any, of the Borrower for the payment of fees or other charges deemed to be interest under applicable law shall be suspended. During any period or periods of time following a Limitation Period, to the extent permitted by applicable laws of the State
of Texas or the United States of America, the interest rate to be charged hereunder shall remain at the Highest Lawful Rate until such time as there has been paid to the Agent for the account of the Lenders (i) the amount of interest in excess
of that accruing at the Highest Lawful Rate that the Agent would have received during the Limitation Period had the interest rate remained at the otherwise applicable rate, and (ii) all interest and fees otherwise payable to the Agent but for
the effect of such Limitation Period.



- 24 -



---

(c) If, under any circumstances, the aggregate amounts paid on the Notes, or any of them, or under this
Agreement or any other Loan Document include amounts which by law are deemed interest and which would exceed the amount permitted if the Highest Lawful Rate were in effect, the Borrower stipulates that such payment and collection will have been and
will be deemed to have been, to the extent permitted by applicable laws of the State of Texas or the United States of America, the result of mathematical error on the part of the Borrower, the Agent and the Lenders; and the Agent, on behalf of
itself and the Lenders, shall promptly refund the amount of such excess (to the extent only of such interest payments in excess of that which would have accrued and been payable on the basis of the Highest Lawful Rate) upon discovery of such error
by the Agent or notice thereof from the Borrower. In the event that the maturity of any Obligation is accelerated, by reason of an election by the Agent or otherwise, or in the event of any required or permitted prepayment, then the consideration
constituting interest under applicable laws may never exceed the Highest Lawful Rate; and excess amounts paid which by law are deemed interest, if any, shall be credited by the Agent on the principal amount of the Obligations, or if the principal
amount of the Obligations shall have been paid in full, refunded to the Borrower.

(d) All sums paid, or agreed to be paid, to the Agent,
for the account of the Lenders, for the use, forbearance and detention of the proceeds of any advance hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full term hereof until
paid in full so that the actual rate of interest is uniform but does not exceed the Highest Lawful Rate throughout the full term hereof.

2.18 Yield Protection. (a) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent, for the account of the Lenders, from time to time such amounts as the
Agent or the Lenders may determine are necessary to compensate the Lenders for any Additional Costs incurred by the Lenders.

(b) Without
limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent, for the account of the Lenders, from time to time on request such amounts as the Agent or the Lenders may determine are
necessary to compensate the Lenders for any costs attributable to the maintenance by the Lenders (or any Applicable Lending Office), pursuant to any Regulatory Change, of capital in respect of the Commitment, such compensation to include, without
limitation, an amount equal to any reduction of the rate of return on assets or equity of the Lenders (or any Applicable Lending Office) to a level below that which the Lenders (or any Applicable Lending Office) could have achieved but for such
Regulatory Change.

(c) Without limiting the effect of the other provisions of this Section (but without duplication), in the event that
any Requirement of Law or Regulatory Change or the compliance by the Agent or the Lenders therewith shall (i) impose, modify, or hold applicable any reserve, special deposit, or similar requirement against any Letter of Credit or obligation to
issue Letters of Credit, or (ii) impose upon the Agent or the Lenders any other condition regarding any Letter of Credit or obligation to issue Letters of Credit, and the result of any such event shall be to increase the cost to the Lenders of
issuing or maintaining any Letter of Credit or obligation to issue Letters of Credit or any liability with respect to payments by the Lenders under Letters of Credit, or to reduce any amount receivable in connection therewith, then within



- 25 -



---

15 days of demand by the Agent, the Borrower shall pay to the Agent, for the account of the Lenders, from time to time as specified by the Agent, additional
amounts which shall be sufficient to compensate the Lenders for such increased cost or reduced amount receivable.

(d) Without limiting the
effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent, for the account of the Lenders, such amounts as shall be sufficient in the reasonable opinion of the Agent to compensate the Lenders for
any loss, cost, or expense incurred by and as a result of:

(i) any payment, prepayment, or conversion by the Borrower of a
LIBO Rate Loan on a date other than the last day of an Interest Period for such Loan; or

(ii) any failure by the Borrower
to borrow a LIBO Rate Loan on the date for such borrowing specified in the relevant Borrowing Request;

such compensation to include, without limitation,
with respect to any LIBO Rate Loan, an amount equal to the excess, if any, of (A) the amount of interest which would have accrued on the principal amount so paid, prepaid, converted, or not borrowed for the period from the date of such payment,
prepayment, conversion, or failure to borrow to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date of such failure to
borrow) at the applicable rate of interest for such Loan provided for herein over (B) the interest component (as reasonably determined by the Agent) of the amount (as reasonably determined by the Agent) the Lenders would have bid in the London
interbank market for Dollar deposits of amounts comparable to such principal amount and maturities comparable to such period; provided, however, that the Agent, on behalf of the Lenders, shall be limited to recover their actual losses and not
anticipated profits.

(e) Determinations by the Agent or the Lenders for purposes of this Section of the effect of any Regulatory Change on
capital maintained, their costs or rate of return, maintaining Loans, issuing Letters of Credit, the Lenders obligations to make Loans and issue Letters of Credit, or on amounts receivable by them in respect of Loans, Letters of Credit, or
such obligations, and the additional amounts required to compensate the Lenders under this Section, shall be rebuttable presumptions of the additional amounts due, provided that such determinations are made on a reasonable basis. The Agent shall
furnish the Borrower with a certificate setting forth in reasonable detail the basis and amount of increased costs incurred or reduced amounts receivable as a result of any such event, and the statements set forth therein shall be rebuttable
presumptions of the additional amounts due. The Agent, on behalf of the Lenders, shall (i) notify the Borrower, as promptly as practicable after the Agent obtains knowledge of any Additional Costs or other sums payable pursuant to this Section
and determines to request compensation therefore, of any event occurring after the Closing Date which will entitle the Lenders to compensation pursuant to this Section; provided that the Borrower shall not be obligated for the payment of any
Additional Costs or other sums payable pursuant to this Section after the earlier of (A) the Final Maturity (provided that the Obligations have been paid in full) and (B) the expiration of the Commitment (provided that the Obligations



- 26 -



---

have been paid in full) to the extent such Additional Costs or other sums accrued more than 90 days prior to the date upon which the Borrower was given such
notice; and (ii) designate a different Applicable Lending Office for the Loans of the Lenders affected by such event if such designation will avoid the need for or reduce the amount of such compensation and will not, in the sole opinion of the
Lenders, be materially disadvantageous to the Lenders. If the Lenders request compensation from the Borrower under this Section, the Borrower may, by notice to the Agent, require that the Loans by the Lenders of the type with respect to which such
compensation is requested be converted into Floating Rate Loans in accordance with Section 2.11. Any compensation requested pursuant to this Section shall be due and payable to the Agent, for the account of the Lenders, within fifteen days of
delivery of any such notice by the Agent to the Borrower.

(f) Each of the Lenders agree that it shall not request, and the Borrower shall
not be obligated to pay, any Additional Costs or other sums payable pursuant to this Section unless similar additional costs and other sums payable are also generally assessed by such Lender against other customers of such Lender similarly situated
where such customers are subject to documents providing for such assessment.

2.19 Limitation of Types of Loans. Anything herein to
the contrary notwithstanding, no more than seven separate Loans shall be outstanding at any one time, with, for purposes of this Section, all Floating Rate Loans constituting one Loan and all LIBO Rate Loans for the same Interest Period constituting
one Loan. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any interest rate for any LIBO Rate Loan for any Interest Period therefor:

(a) the Lenders determine (which determination shall be conclusive) that quotations of interest rates for the deposits referred to in the
definition of LIBO Rate in Section 1.2 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining the rate of interest for such Loan as provided in this Agreement; or

(b) the Lenders determine (which determination shall be conclusive) that the rates of interest referred to in the definition of LIBO
Rate in Section 1.2 upon the basis of which the rate of interest for such Loan for such Interest Period is to be determined do not accurately reflect the cost to the Lenders of making or maintaining such Loan for such Interest Period,

then the Agent shall give the Borrower prompt notice thereof; and so long as such condition remains in effect, the Lenders shall be under no obligation to
make LIBO Rate Loans or to convert Loans of any other type into LIBO Rate Loans, and the Borrower shall, on the last day of the then current Interest Period for each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or convert such Loan
into another type of Loan in accordance with Section 2.11. Before giving such notice pursuant to this Section, the Agent will designate a different available Applicable Lending Office for LIBO Rate Loans or take such other action as the
Borrower may request if such designation or action will avoid the need to suspend the obligation of the Lenders to make LIBO Rate Loans hereunder and will not, in the opinion of the Agent, be materially disadvantageous to the Agent or the Lenders.



- 27 -



---

2.20 Illegality. Notwithstanding any other provision of this Agreement, in the event that it
becomes unlawful for the Lenders or their Applicable Lending Office to (a) honor its obligation to make any type of LIBO Rate Loans hereunder, or (b) maintain any type of LIBO Rate Loans hereunder, then the Agent shall promptly notify the
Borrower thereof; and the obligation of the Lenders hereunder to make such type of LIBO Rate Loans and to convert other types of Loans into LIBO Rate Loans of such type shall be suspended until such time as the Lenders may again make and maintain
LIBO Rate Loans of such type, and the outstanding LIBO Rate Loans of such type shall be converted into Floating Rate Loans in accordance with Section 2.11. Before giving such notice pursuant to this Section, the Agent will designate a different
available Applicable Lending Office for LIBO Rate Loans or take such other action as the Borrower may request if such designation or action will avoid the need to suspend the obligation of the Lenders to make LIBO Rate Loans and will not, in the
opinion of the Agent, be disadvantageous to the Agent or the Lenders.

2.21 Regulatory Change. In the event that by reason of any
Regulatory Change, the Lenders (a) incur Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of the Lenders which includes deposits by reference to which the
interest rate on any LIBO Rate Loan is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lenders which includes any LIBO Rate Loan, or (b) becomes subject to restrictions on the amount of
such a category of liabilities or assets which it may hold, then, at the election of the Agent with notice to the Borrower, the obligation of the Lenders to make such LIBO Rate Loans and to convert Floating Rate Loans into such LIBO Rate Loans shall
be suspended until such time as such Regulatory Change ceases to be in effect, and all such outstanding LIBO Rate Loans shall be converted into Floating Rate Loans in accordance with Section 2.11.

2.22 Limitations on Interest Periods. Each Interest Period selected by the Borrower (a) which commences on the last Business Day of a
calendar month (or, with respect to any LIBO Rate Loan, any day for which there is no numerically corresponding day in the appropriate subsequent calendar month) shall end on the last Business Day of the appropriate subsequent calendar month,
(b) which would otherwise end on a day which is not a Business Day shall end on the next succeeding Business Day (or, with respect to any LIBO Rate Loan, if such next succeeding Business Day falls in the next succeeding calendar month, on the
next preceding Business Day), (c) which would otherwise commence before and end after Final Maturity shall end on Final Maturity, and (d) shall have a duration of not less than one month, as to any LIBO Rate Loan, and, if any Interest
Period would otherwise be a shorter period, the relevant Loan shall be a Floating Rate Loan during such period.

2.23 Letters in Lieu of
Transfer Orders. The Agent agrees that none of the letters in lieu of transfer or division orders provided by the Borrower will be sent to the addressees thereof prior to the occurrence of an Event of Default, at which time the Agent may, at its
option and in addition to the exercise of any of its other rights and remedies, send any or all of such letters.

2.24 Power of
Attorney. The Borrower hereby designates the Agent as its agent and attorney-in-fact, to act in its name, place, and stead for the purpose of completing and, upon the occurrence of an Event of Default, delivering any and all of the letters in
lieu of transfer or division orders delivered by the Borrower to the Agent, including completing any blanks

contained in such letters and attaching exhibits thereto describing the relevant Collateral. The Borrower hereby ratifies and confirms all that the Agent
shall lawfully do or cause to be done by virtue of this power of attorney and the rights granted with respect to such power of attorney. This power of attorney is coupled with the interests of the Agent (for the benefit of the Lenders) in the
Collateral, shall commence and be in full force and effect as of the Closing Date and shall remain in full force and effect and shall be irrevocable so long as any Obligation remains outstanding or unpaid or any Commitment exists. The powers
conferred on the Agent by this appointment are solely to protect the interests of the Agent and the Lenders under the Loan Documents and shall not impose any duty upon the Agent to exercise any such powers. The Agent shall be accountable only for
amounts that it actually receives as a result of the exercise of such powers and shall not be responsible to the Borrower or any other Person for any act or failure to act with respect to such powers, except for gross negligence or willful
misconduct.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

To induce the Agent and the Lenders to enter into this Agreement and to make the Loans and issue Letters of Credit, the Borrower represents and warrants to the Agent and the Lenders (which representations and warranties shall survive the
delivery of the Notes) that:

4.1 Due Authorization. The execution and delivery by the Borrower of this Agreement and the borrowings
hereunder, the execution and delivery by the Borrower of the Notes, the repayment of the Notes and interest and fees provided for in the Notes and this Agreement, the execution and delivery of the Security Instruments by the Borrower and the
performance of all obligations of the Borrower under the Loan Documents, are within the power of the Borrower, have been duly authorized by all necessary limited liability company action by the Borrower, and do not and will not (a) require the
consent of any Governmental Authority, (b) contravene or conflict with any Requirement of Law, (c) contravene or conflict with any indenture, instrument, or other agreement to which the Borrower is a party or by which any Property of the
Borrower may be presently bound or encumbered, except where such contravention or conflict would not individually or in the aggregate result in a Material Adverse



- 31 -



---

Effect, or (d) result in or require the creation or imposition of any Lien in, upon or of any Property of the Borrower under any such indenture,
instrument, or other agreement, other than the Loan Documents.

4.2 Limited Liability Company Existence. The Borrower is a limited
liability company duly organized, legally existing, and in good standing under the laws of its state of formation and is duly qualified as foreign limited liability company and is in good standing in all jurisdictions wherein the ownership of
Property or the operation of its business necessitates same, other than those jurisdictions wherein the failure to so qualify will not have a Material Adverse Effect.

4.3 Valid and Binding Obligations. All Loan Documents, when duly executed and delivered by the Borrower, will be the legal, valid, and binding obligations of the Borrower, enforceable against the Borrower in
accordance with their respective terms except as enforceability may be limited by applicable bankruptcy, insolvency, or similar laws affecting the enforcement of creditors rights generally or by equitable principles relative to enforceability.

4.4 Security Instruments. The provisions of each Security Instrument are effective to create in favor of the Agent, for the benefit
of the Lenders, a legal, valid, and enforceable Lien in all right, title, and interest of the Borrower in the Collateral described therein, except as enforceability may be limited by applicable bankruptcy, insolvency, or similar laws affecting the
enforcement of creditors rights generally or by equitable principles relative to enforceability, which Liens, assuming the accomplishment of recording and filing in accordance with applicable laws prior to the intervention of rights of other
Persons, shall constitute fully perfected first-priority Liens on all right, title, and interest of the Borrower in the Collateral described therein subject to Permitted Liens.

4.5 Title to Assets. The Borrower has good and indefeasible title to all of its interests in its Properties then owned by it, free and clear of
all Liens except Permitted Liens.

4.6 No Material Misstatements. As of the Closing Date, no information, exhibit, statement, or
report furnished to the Lender by or at the direction of the Borrower in connection with this Agreement contains any material misstatement of fact or omits to state a material fact or any fact necessary to make the statements contained therein not
misleading as of the date made or deemed made.

4.7 Liabilities, Litigation, and Restrictions. As of the Closing Date, other than as
reflected and reported in Borrowers Financial Statements as of March 31, 2006, including the due to related parties, the Borrower has no liabilities, direct, or contingent, which would result in a Material Adverse Effect, no litigation or
other action of any nature affecting the Borrower is pending before any Governmental Authority or, to the best knowledge of the Borrower, threatened against or affecting the Borrower which might reasonably be expected to result in any material
impairment of its ownership of any Collateral or have a Material Adverse Effect. To the best knowledge of the Borrower, after due inquiry, no unusual or unduly burdensome restriction, restraint or hazard exists by contract, Requirement of Law, or
otherwise relative to the business or operations of the Borrower or the ownership and operation of the Collateral would result in a Material Adverse Effect, other than such as relate generally to Persons engaged in business activities similar to
those conducted by the Borrower.

4.8 Authorizations; Consents. Except as expressly contemplated by this Agreement, no
authorization, consent, approval, exemption, franchise, permit, or license of, or filing with, any Governmental Authority or any other Person is required to authorize or is otherwise required in connection with the valid execution and delivery by
the Borrower of the Loan Documents or any instrument contemplated hereby, the repayment by the Borrower of the Notes and interest and fees provided in the Notes and this Agreement, or the performance by the Borrower of the Obligations.

4.9 Compliance with Laws. The Borrower and its Property, including, without limitation, the Mortgaged Property, are in compliance with all
material applicable Requirements of Law, including, without limitation, Environmental Laws, the Natural Gas Policy Act of 1978, as amended, and ERISA, except to the extent non-compliance with any such Requirements of Law could not reasonably be
expected to have a Material Adverse Effect.

4.10 ERISA. No Reportable Event has occurred with respect to any Single Employer Plan,
and each Single Employer Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. To the knowledge of the Borrower, (a) no Reportable Event has occurred with respect
to any Multiemployer Plan, and (b) each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Single Employer
Plan maintained by the Borrower or any Commonly Controlled Entity (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such
vested benefits. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable to any
Multiemployer Plan, neither the Borrower nor any Commonly Controlled Entity would become subject to any liability under ERISA if the Borrower or such Commonly Controlled Entity were to withdraw completely from such Multiemployer Plan. Neither the
Borrower nor any Commonly Controlled Entity has received notice that any Multiemployer Plan is Insolvent or in Reorganization. To the knowledge of the Borrower, no such Insolvency or Reorganization is reasonably likely to occur. Based upon GAAP
existing as of the date of this Agreement and current factual circumstances, the Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower and all Commonly Controlled Entities for post-retirement
benefits to be provided to the current and former employees of the Borrower and all Commonly Controlled Entities under Plans which are welfare benefit plans (as defined in Section 3(1) of ERISA) will, in the aggregate, have a Material Adverse
Effect.

4.11 Environmental Laws. To the knowledge and belief of the Borrower, except as would not have a Material Adverse Effect:

(a) no Property of the Borrower is currently on or has ever been on, or is adjacent to any Property which is on or has ever
been on, any federal or state list of Superfund Sites;



- 33 -



---

(b) no Hazardous Substances have been generated, transported, and/or disposed of by the
Borrower at a site which was, at the time of such generation, transportation, and/or disposal, or has since become, a Superfund Site;

(c) except in accordance with applicable Requirements of Law or the terms of a valid permit, license, certificate, or approval of the relevant Governmental Authority, no Release of Hazardous Substances by the Borrower
or from, affecting, or related to any Property of the Borrower or adjacent to any Property of the Borrower has occurred; and

(d) no Environmental Complaint has been received by the Borrower.

4.12 Compliance with Federal Reserve Regulations. No
transaction contemplated by the Loan Documents is in violation of any regulations promulgated by the Board of Governors of the Federal Reserve System, including, without limitation, Regulations G, T, U, or X.

4.13 Investment Company Act Compliance. The Borrower is not, nor is the Borrower directly or indirectly controlled by or acting on behalf of any
Person which is, an investment company or an affiliated person of an investment company within the meaning of the Investment Company Act of 1940, as amended.

4.14 RESERVED.

4.15 Proper
Filing of Tax Returns; Payment of Taxes Due. The Borrower has duly and properly filed its United States income tax return and all other tax returns which are required to be filed and has paid all taxes due except such as are being contested in
good faith and as to which adequate provisions and disclosures have been made. The respective charges and reserves on the books of the Borrower with respect to taxes and other governmental charges are adequate.

4.16 Refunds. No orders of, proceedings pending before, or other requirements of, the Federal Energy Regulatory Commission, the Texas Railroad
Commission, or any Governmental Authority exist which could result in the Borrower being required to refund any material portion of the proceeds received or to be received from the sale of hydrocarbons constituting part of the Mortgaged Property.

4.17 Gas Contracts. The Borrower (a) is not obligated in any material respect by virtue of any prepayment made under any
contract containing a take-or-pay or prepayment provision or under any similar agreement to deliver hydrocarbons produced from or allocated to any of the Mortgaged Property at some future date without receiving full payment
therefor within 90 days of delivery, and (b) has not produced gas, in any material amount, subject to, and neither the Borrower nor any of the Mortgaged Properties is subject to, balancing rights of third parties or subject to balancing duties
under governmental requirements, except as to such matters for which the Borrower has reflected in the most recent engineering report or established monetary reserves adequate in amount to satisfy such obligations and has segregated such reserves
from other accounts.



- 34 -



---

4.18 Intellectual Property. The Borrower owns or is licensed to use all Intellectual Property
necessary to conduct all business material to its financial condition, business, or operations as such business is currently conducted. No claim has been asserted or is pending by any Person with the respect to the use of any such Intellectual
Property or challenging or questioning the validity or effectiveness of any such Intellectual Property; and the Borrower knows of no valid basis for any such claim. The use of such Intellectual Property by the Borrower does not infringe on the
rights of any Person, except for such claims and infringements as do not, in the aggregate, give rise to any material liability on the part of the Borrower.

4.19 Casualties or Taking of Property. Except as would not result in a Material Adverse Effect, neither the business nor any Property of the Borrower has been materially adversely affected as a result of any
fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property, or cancellation of contracts, permits, or concessions by any Governmental Authority, riot, activities of
armed forces, or acts of God.

4.20 Locations of Borrower. The principal place of business and chief executive office of the
Borrower is located at the address of the Borrower set forth in Section 9.3 or at such other location as the Borrower may have, by proper written notice hereunder, advised the Agent, provided that such other location is within a state in which
appropriate financing statements from the Borrower in favor of the Agent have been filed.

4.21 Subsidiaries. As of the Closing
Date, the Borrower has no Subsidiaries.

4.22 Compliance with Anti-Terrorism Laws. (a) Neither the Borrower nor any Affiliate
of the Borrower is in violation of any Anti-Terrorism Law or knowingly engages in or conspires to engage in any transaction that evades or avoids, or has the purpose of evading or avoiding, or attempts to violate, any of the prohibitions set forth
in any Anti-Terrorism Law.

(b) Neither the Borrower nor any Affiliate of the Borrower is any of the following (each a Blocked

costs reasonably expected by the Agent to be incurred in connection therewith, (b) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except
for gross negligence or willful misconduct of the Agent or such Person), or (c) responsible in any manner to any Lender for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this
Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agent under or in connection with, this Agreement or any other Loan Document, or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Agent shall not be under any obligation to
any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower.

8.5 Reliance by Agent. The Agent shall be entitled to rely, and shall be fully protected in relying, upon any Note, writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the
proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts selected by the Agent. The Agent may deem and treat the payee of any Note as the owner thereof
for all purposes unless and until a written notice of assignment, negotiation, or transfer thereof shall have been received by the Agent. The Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other
Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and contribution by each Lender of its Percentage Share of costs reasonably expected by the Agent to be incurred in connection
therewith. The Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders. Such request and any action taken or failure
to act pursuant thereto



- 49 -



---

shall be binding upon the Lenders and all future holders of the Notes. In no event shall the Agent be required to take any action that exposes the Agent to
personal liability or that is contrary to any Loan Document or applicable Requirement of Law.

8.6 Notice of Default. The Agent
shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a notice of default. In the event that the Agent receives such a notice, the Agent shall promptly give notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Required Lenders; provided that unless and until the Agent shall have received such directions, subject to the provisions of Section 7.2, the Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. In the event that the officer of the Agent primarily responsible for the lending
relationship with the Borrower or the officer of any Lender primarily responsible for the lending relationship with the Borrower becomes aware that a Default or Event of Default has occurred and is continuing, the Agent or such Lender, as the case
may be, shall use its good faith efforts to inform the other Lenders and/or the Agent, as the case may be, promptly of such occurrence. Notwithstanding the preceding sentence, failure to comply with the preceding sentence shall not result in any
liability to the Agent or any Lender.

8.7 Non-Reliance on Agent and Other Lenders. Each Lender expressly acknowledges that neither
the Agent nor any other Lender nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representation or warranty to such Lender and that no act by the Agent or any other Lender hereafter
taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent or any Lender to any other Lender. Each Lender represents to the Agent that it has, independently and without
reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, condition (financial and otherwise) and
creditworthiness of the Borrower and the value of the Collateral and other Properties of the Borrower and has made its own decision to enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the
Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan
Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, condition (financial and otherwise) and creditworthiness of the Borrower and the value of the Collateral and other Properties
of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial and otherwise), or creditworthiness of the Borrower or the value of the Collateral or other Properties of the Borrower which may come into the possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates.

8.8 Indemnification. EACH LENDER AGREES
TO INDEMNIFY THE AGENT AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT AND AFFILIATES (TO THE EXTENT NOT REIMBURSED BY THE
BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO
SO), RATABLY ACCORDING TO THE PERCENTAGE SHARE OF SUCH LENDER, FROM
AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND
WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING ANY TIME FOLLOWING THE
PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS
AGREEMENT) BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT
OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT
OR AFFILIATES IN ANY WAY RELATING TO OR ARISING OUT OF THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER DOCUMENT CONTEMPLATED
OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY
ACTION TAKEN OR OMITTED BY THE AGENT OR ANY OF ITS OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN
CONNECTION WITH ANY OF THE FOREGOING, INCLUDING ANY LIABILITIES, CLAIMS,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND
DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE,
WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY OF ITS OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO
LENDER SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES
OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT OR AFFILIATES. THE AGREEMENTS IN THIS SECTION SHALL
SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION
OF THIS AGREEMENT.

8.9 Restitution. Should the right of the Agent or any Lender to
realize funds with respect to the Obligations be challenged and any application of such funds to the Obligations be reversed, whether by Governmental Authority or otherwise, or should the Borrower otherwise be entitled to a refund or return of funds
distributed to the Lenders in connection with the Obligations, the Agent or such Lender, as the case may be, shall promptly notify the Lenders of such fact. Not later than Noon, Central Standard or Central Daylight Savings Time, as the case may be,
of the Business Day following such notice, each Lender shall pay to the Agent an amount equal to the ratable share of such Lender of the funds required to be returned to the Borrower. The ratable share of each Lender shall be determined on the basis
of the percentage of the payment all or a portion of which is required to be refunded originally distributed to such Lender, if such percentage can be determined, or, if such percentage cannot be determined, on the basis of the Percentage Share of
such Lender. The Agent shall forward such funds to the Borrower or to the Lender required to return such funds. If any such amount due to the Agent is made available by any Lender after Noon, Central Standard or Central Daylight Savings Time, as the
case may be, of the Business Day following such notice, such Lender shall pay to the Agent (or the Lender required to return funds to the Borrower, as the case may be) for its own account interest on such amount at a rate equal to the Federal Funds
Rate for the period from and including the date on which restitution to the Borrower is made by the Agent (or the Lender required to return funds to the Borrower, as the case may be) to but not including the date on which such Lender failing to
timely forward its share of funds required to be returned to the Borrower shall have made its ratable share of such funds available.

8.10 Agent in Its Individual Capacity. The Agent and its affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrower as though the Agent were not the agent hereunder. With respect to any Note issued to the Lender serving as the Agent, the Agent shall have the same rights and powers under
this Agreement as a Lender and may exercise such rights and powers as though it were not the Agent. The terms Lender and Lenders shall include the Agent in its individual capacity.

8.11 Successor Agent. The Agent may resign as Agent upon ten (10) days notice to the Lenders and the Borrower. If the Agent shall
resign as Agent under this Agreement and the other Loan Documents, Lenders for which the Percentage Shares aggregate at least fifty-one percent (51%) shall appoint from among the Lenders a successor agent for the Lenders, subject to the
reasonable consent of the Borrower, whereupon such successor agent shall succeed to the rights, powers and duties of the Agent. The term Agent shall mean such successor agent effective upon its appointment. The rights, powers, and duties
of the former Agent as Agent shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Notes. After the removal or resignation of any Agent hereunder
as Agent, the provisions of this Article VIII and those of any Section hereof relating to the Agent, including Section 5.17, Section 5.18, and Section 5.22, shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents.

8.12 Applicable Parties.
The provisions of this Article are solely for the benefit of the Agent and the Lenders, and the Borrower shall not have any rights as a third party beneficiary or otherwise under any of the provisions of this Article. In performing functions and
duties hereunder and under the other Loan Documents, the Agent shall act solely as the agent of the Lenders and does not assume, nor shall it be deemed to have assumed, any obligation or relationship of trust or agency with or for the Borrower or
any legal representative, successor, and assign of the Borrower.

8.13 Subordination Agreements. In furtherance of the authority
granted to the Agent in Section 8.1 and elsewhere in this Agreement, each of the Lenders authorizes the Agent to execute and, by such execution, to bind such Lender to the terms of each of the Subordination Agreements and agrees to be
bound by the terms of each of the Subordination Agreements as fully as if a signatory thereto.

ARTICLE IX

MISCELLANEOUS

9.1
Transfers; Participations. Each Lender may assign or sell participations in its Loans and Commitments to one or more other Persons in accordance with this Section 9.1.



- 52 -



---

(a) Assignments. Any Lender,

(i) with the written consent of the Borrower and the Agent (which consent shall not be unreasonably delayed or withheld), may at any time,
assign and delegate to one or more commercial banks or other financial institutions, and

(ii) with notice to the Borrower
and the Agent, but without the consent of the Borrower or the Agent, may assign and delegate to any of its Affiliates or to any other Lender

(each Person
described in (i) or (ii) above as being the Person to whom such assignment and delegation is to be made, being hereinafter referred to as an Assignee Lender), all or any fraction of such Lenders total Loans and
Commitments (which assignment and delegation shall be of a constant, and not a varying percentage, of all the assigning Lenders Loans and Commitments), in a minimum aggregate amount of $1,000,000 of such Lenders Percentage Share of the
Maximum Commitment Amount; provided, however, that such Assignee Lender will comply with all the provisions of this Agreement, and further, provided, however, that the Borrower and Agent shall be entitled to continue to deal solely and directly with
such assigning Lender in connection with the interests so assigned and delegated to an Assignee Lender until:

(iii) written
notice of such assignment and delegation together with payment instructions, addresses and related information with respect to such Assignee Lender, shall have been given to the Borrower and the Agent by such Lender and such Assignee Lender,

(iv) such Assignee Lender shall have executed and delivered to the Borrower and the Agent a Lender Assignment Agreement,
accepted by the Borrower and the Agent and attached hereto as Exhibit VII, and

(v) the processing fees described below
shall have been paid.

From and after the date that the Borrower and the Agent accept such Lender Assignment Agreement, (a) the Assignee Lender
thereunder shall be deemed automatically to have become a party hereto and, to the extent that rights and obligations hereunder have been assigned and delegated to such Assignee Lender in connection with such Lender Assignment Agreement, shall have
the rights and obligations of a Lender hereunder and under the other Loan Documents, and (b) the assignor Lender, to the extent that rights and obligations hereunder have been assigned and delegated by it in connection with such Lender
Assignment Agreement, shall be released from its obligations hereunder and under the other Loan Documents. Within five Business Days after its receipt of notice that the Agent has received an executed Lender Assignment Agreement, the Borrower shall
execute and deliver to the Agent (for delivery to the relevant Assignee Lender) new Notes evidencing such Assignee Lenders assigned Loans and Commitments and, if the assignor Lender has retained Loans and Commitments hereunder, replacement

principal amount of the Loans and Commitments retained by the assignor Lender hereunder (such Notes to be in exchange for, but not in payment of, those Notes
then held by such assignor Lender). Each such Note shall be dated the date of the predecessor Notes. The assignor Lender shall mark the predecessor Notes exchanged and deliver them to the Borrower. Accrued interest on that part of the
predecessor Notes evidenced by the new Notes, and accrued fees, shall be paid as provided in the Lender Assignment Agreement. Accrued interest on that part of the predecessor Notes evidenced by the replacement Notes shall be paid to the assignor
Lender. Accrued interest and accrued fees shall be paid at the same time or times provided in the predecessor Notes and in this Agreement. Such assignor Lender or such Assignee Lender must also pay a processing fee to the Agent upon delivery of any
Lender Assignment Agreement in the amount of $3,000. Any attempted assignment and delegation not made in accordance with this Section 9.1 shall be null and void.

(b) Participations. Any Lender, with the prior written consent of the Borrower in its sole discretion, may at any time sell to one or more commercial banks (each of such commercial banks being herein called a
Participant) participating interests in any of the Loans, Commitments, or other interests of such Lender hereunder; provided, however, that (a) no participation contemplated in this Section 9.1 shall relieve such Lender
from its Commitments or its other obligations hereunder or under any other Loan Document, (b) such Lender shall remain solely responsible for the performance of its Commitments and such other obligations, (c) the Borrower and the Agent
shall continue to deal solely and directly with such Lender in connection with such Lenders rights and obligations under this Agreement and each of the other Loan Documents, (d) no Participant shall be entitled to require such Lender to
take or refrain from taking any action hereunder or under any other Loan Document.

9.2 Survival of Representations, Warranties, and
Covenants. All representations and warranties of the Borrower and all covenants and agreements herein made shall survive the execution and delivery of the Notes and the Security Instruments and shall remain in force and effect so long as any
Obligation is outstanding or any Commitment exists.

9.3 Notices and Other Communications. Except as to oral notices expressly
authorized herein, which oral notices shall be confirmed in writing, all notices, requests, and communications hereunder shall be in writing (including facsimile or other electronic form). Unless otherwise expressly provided herein, any such notice,
request, demand, or other communication shall be deemed to have been duly given or made when delivered by hand, or, in the case of delivery by mail, when deposited in the mail, certified mail, return receipt requested, postage prepaid, or, in the
case of facsimile or other electronic notice, when receipt thereof is acknowledged orally or by written confirmation report, addressed as follows:

hereto or in a relevant Assignment Agreement.

Any party may, by proper written notice hereunder to the others, change the individuals or
addresses to which such notices to it shall thereafter be sent.

9.4 Parties in Interest. Subject to applicable restrictions
contained herein, all covenants and agreements herein contained by or on behalf of the Borrower, the Agent or the Lenders shall be binding upon and inure to the benefit of the Borrower, the Agent or the Lenders, as the case may be, and their
respective legal representatives, successors, and assigns.

9.5 Rights of Third Parties. All provisions herein are imposed solely
and exclusively for the benefit of the Agent, Lenders and the Borrower. No other Person shall have any right, benefit, priority, or interest hereunder or as a result hereof or have standing to require satisfaction of provisions hereof in accordance
with their terms.

9.6 Renewals; Extensions. All provisions of this Agreement relating to the Notes shall apply with equal force and
effect to each promissory note hereafter executed which in whole or in part represents a renewal or extension of any part of the Indebtedness of the Borrower under this Agreement, the Notes, or any other Loan Document.

9.7 No Waiver; Rights Cumulative. No course of dealing on the part of the Agent or a Lender, its officers or employees, nor any failure or delay
by the Agent or a Lender with respect to exercising any of its rights under any Loan Document shall operate as a waiver thereof. The rights of the Agent or a Lender under the Loan Documents shall be cumulative and the exercise or partial exercise of
any such right shall not preclude the exercise of any other right. Neither the making of any Loan nor the issuance of a Letter of Credit shall constitute a waiver of any of the covenants, warranties, or conditions of the Borrower contained herein.
In the event the Borrower is unable to satisfy any such covenant, warranty, or condition, neither the making of any Loan nor the issuance of a Letter of Credit shall have the effect of precluding the Agent from thereafter declaring such inability to
be an Event of Default as hereinabove provided.

9.8 Survival Upon Unenforceability. In the event any one or more of the provisions
contained in any of the Loan Documents or in any other instrument referred to herein or executed in connection with the Obligations shall, for any reason, be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality,
or unenforceability shall not affect any other provision of any Loan Document or of any other instrument referred to herein or executed in connection with such Obligations.

9.9 Amendments; Waivers. Neither this Agreement nor any provision hereof may be amended, waived,
discharged, or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the amendment, waiver, discharge, or termination is sought.

9.10 Controlling Agreement. In the event of a conflict between the provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control.

9.11 Disposition of Collateral. Notwithstanding any term or provision, express or
implied, in any of the Security Instruments, the realization, liquidation, foreclosure, or any other disposition on or of any or all of the Collateral shall be in the order and manner and determined in the sole discretion of the Agent; provided,
however, that in no event shall the Agent violate applicable law or exercise rights and remedies other than those provided in such Security Instruments or otherwise existing at law or in equity.

9.12 USA Patriot Act Notice. The Agent hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act the Agent is required
to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow the Agent to identify the Borrower in accordance with the USA Patriot Act.

9.13 Tax Shelter Regulations. The Borrower does not intend to treat the Loans and related transactions hereunder and under the
other Loan Documents as a reportable transaction (within the meanings under current Treasury Regulation Section 1.6011-4 and Proposed Treasury Regulation Section 1.6011-4, promulgated on November 1, 2006). In the event the
Borrower determines to take any action inconsistent with the foregoing statement, it will promptly notify the Agent thereof. If the Borrower so notifies the Agent, the Borrower acknowledges that the Agent and the Lenders may treat the Loans and
related transactions hereunder and under the other Loan Documents as part of a transaction that is subject to current Treasury Regulation Section 301.6112-1 or Proposed Treasury Regulation Section 301.6112-1, promulgated on
November 1, 2006, and, in such case, the Agent will maintain the lists and other records required, if any, by such Treasury Regulations.

RELATED TO, OR FROM THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY
BE LITIGATED, AT THE SOLE DISCRETION AND ELECTION OF THE LENDER, IN
COURTS HAVING SITUS IN HOUSTON, HARRIS COUNTY, TEXAS. THE BORROWER HEREBY
SUBMITS TO THE JURISDICTION OF ANY LOCAL, STATE, OR FEDERAL COURT
LOCATED IN HOUSTON, HARRIS COUNTY, TEXAS, AND HEREBY WAIVES ANY RIGHTS
IT MAY HAVE TO TRANSFER OR CHANGE THE JURISDICTION OR VENUE OF
ANY LITIGATION BROUGHT AGAINST IT BY THE AGENT OR ANY LENDER IN

9.16 Waiver of rights to jury trial. THE BORROWER,
THE AGENT AND THE LENDERS HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY,
AND UNCONDITIONALLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION,
