 ARTICLE II 

TERMS OF FACILITY 
 2.1 Revolving Line of Credit and Letter of Credit Facility. 
 (a) Upon the
terms and conditions (including the right of the Lenders to decline to make any Loan, other than a Letter of Credit Payment, so long as any condition to the making of such Loan set forth in Section 3.2 has not been satisfied) and relying
on the representations and warranties contained in this Agreement, each Lender severally agrees to make Loans during the Commitment Period to or for the benefit of the Borrowers in an aggregate outstanding principal amount not to exceed at any time
the Percentage Share of such Lender of the Commitment Amount then in effect (but such product not to exceed, at any time, the Facility Amount of the relevant Lender then in effect), minus the Percentage Share of such Lender of the then existing L/C
Exposure. Loans shall be made from time to time on any Business Day designated in a Borrowing Request. 
 (b) Subject to the
provisions of this Agreement, during the Commitment Period, the Borrowers may borrow, repay, and reborrow and convert Loans of one type or with one Interest Period into Loans of another type or with a different Interest Period. Each borrowing or
conversion of principal of (i) Base Rate Loans shall be in an amount at least equal to $500,000 and a whole multiple of $100,000 and (ii) LIBO Rate Loans shall be in an amount at least equal to $500,000 and a whole multiple of $100,000
and, if any LIBO Rate Loan would otherwise be in a lesser principal amount for any period, such Loan shall be a Base Rate Loan during such period. Except for prepayments made pursuant to the provisions of Section 2.11, each prepayment of
principal shall be in an amount at least equal to $10,000 and a whole multiple of $5,000. 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. 
 (c) The Agent shall notify each Lender of its receipt of a Borrowing Request as soon as practicable following its receipt thereof, including in such notice the amount of the requested Loan and the
requested date for the making of the requested Loan. Not later than 11:00 a.m., Central Standard or Central Daylight Savings Time, as the case may be, on the date specified for each borrowing, each Lender shall make available to the Agent, at an
account designated by the Agent, an amount equal to the Percentage Share of such Lender of the borrowing to be made on such date. 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. All Loans by each Lender shall be maintained at the Applicable Lending Office of such Lender and shall be evidenced by the Note of such Lender. 

(d) The failure of any Lender to make any Loan required to be made by it hereunder shall not relieve any other Lender of its obligation
to make any Loan required to be made by it, and no Lender shall be responsible for the failure of any other Lender to make any Loan.

 (e) Upon the terms and
conditions (including the right of the Agent to decline to issue renew or extend any Letter of Credit so long as any condition to the issuance, renewal or extension of such Letter of Credit set forth in Section 3.3 has not been
satisfied) 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 30 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 either or both of the Borrowers 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 either of the Borrowers 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 either of
the Borrowers therefor and a Letter of Credit Application. Letters of Credit shall be issued in such amounts as either of the Borrowers may request; provided, however, that (i) no Letter of Credit shall have an expiration date
which is less than 30 days prior to the Commitment Termination Date, (ii) the Loan Balance plus the L/C Exposure, including that under any then requested Letter of Credit, shall not exceed at any time the Commitment Amount, (iii) the L/C
Exposure, including that under any then requested Letter of Credit, shall not exceed at any time the L/C Sublimit and (iv) no Letter of Credit shall be issued in an amount less than $10,000. 

(f) In connection with the issuance, renewal or extension by the Agent of any Letter of Credit pursuant to Section 2.1(e),
the Borrowers shall pay to the Agent, for the account of the Lenders, a letter of credit fee in an amount equal to the greater of (i) the face amount of such Letter of Credit multiplied by a per annum rate of three and one-quarter percent
(3.25%), calculated on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day), or (ii) $350. Such fee with respect to each Letter of Credit shall be payable on
the date of issuance, renewal or extension of the relevant Letter of Credit. Neither the Agent nor any Lender shall have any obligation to refund any portion of any such fee upon early cancellation of the relevant Letter of Credit. The Borrowers
also agree to pay on demand to the Agent, solely for its account as issuer of the relevant Letter of Credit, its customary letter of credit transaction fees and expenses, including amendment fees, payable with respect to each Letter of Credit.

 (g) The Borrowers agree that neither the Agent nor any Lender shall be responsible for, nor shall the Obligations be affected
by, among other things, (i) the validity or genuineness of documents or any endorsements thereon presented in connection with any Letter of Credit, even if such documents shall in fact prove to be in any and all respects invalid, fraudulent or
forged, so long as the Agent, as the issuer of such Letter of Credit, has no actual knowledge of any such invalidity, lack of genuineness, fraud, or forgery prior to the presentment for payment of a corresponding Letter of Credit or any draft
thereunder or (ii) any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other Person to which any Letter of Credit may be transferred, or any claims whatsoever of either of the Borrowers against any
beneficiary of any Letter of Credit or any such transferee. The Borrowers further acknowledge and agree that the Agent, as the issuer of Letters of Credit, shall be liable to the Borrowers to the extent, but only to the extent, of any direct, as
opposed to consequential or punitive, damages suffered by either of the Borrowers as a result of the willful misconduct or gross negligence of the Agent as the issuer of Letters of Credit in determining whether documents presented under a Letter of
Credit complied with the terms of such Letter of Credit 

  
 - 21 -








 
that resulted in either a wrongful payment under such Letter of Credit or a wrongful dishonor of a claim or draft properly presented under such Letter of Credit. In the absence of gross
negligence or willful misconduct by the Agent as the issuer of Letters of Credit, the Agent shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in
connection with any Letter of Credit. The Agent, the Lenders, and the Borrowers agree that any action taken or omitted by the Agent, as issuer of any Letter of Credit, under or in connection with any Letter of Credit or the related drafts or
documents, if done in the absence of gross negligence or willful misconduct, shall be binding as among the Agent, as issuer of such Letter of Credit or otherwise, the Lenders, and the Borrowers and shall not put the Agent, as issuer of such Letter
of Credit or otherwise, or any Lender under any liability to the Borrowers. 
 (h) Unless either of the Borrowers provides to
the Agent funds sufficient to allow the Agent to pay any drawing by a beneficiary under a Letter of Credit prior to the Agent being obligated to pay the relevant drawing under a Letter of Credit, the Agent shall make a Letter of Credit Payment in
payment of such drawing. Prior to any Letter of Credit 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 2.1(i), 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 Borrowers 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. 
 (i) 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 Letter of Credit Payment shall be deemed to be a Loan by
each Lender to the extent of funds delivered by such Lender to the Agent with respect to such Letter of Credit Payment and shall to such extent be deemed a Loan under and shall be evidenced by the Note of such Lender and shall be payable by the
Borrowers upon demand by the Agent. 
 (j) EACH LENDER AGREES TO
INDEMNIFY THE AGENT, AS THE ISSUER OF EACH LETTER OF CREDIT, AND
THE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS IN FACT AND AFFILIATES OF
THE AGENT (TO THE EXTENT NOT REIMBURSED BY EITHER OF THE BORROWERS
AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWERS TO DO SO),
RATABLY ACCORDING TO THE PERCENTAGE SHARE OF SUCH LENDER AT THE TIME
OF ISSUANCE OF SUCH LETTER OF CREDIT, 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 AS THE ISSUER OF SUCH
LETTER OF CREDIT OR ANY OF ITS OFFICERS, 

  
 - 22 -








 
DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS IN FACT OR AFFILIATES
IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR
SUCH LETTER OF CREDIT OR ANY ACTION TAKEN OR OMITTED BY THE
AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT 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 AS THE ISSUER OF
SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO LENDER
(OTHER THAN THE AGENT AS THE ISSUER OF A LETTER OF CREDIT)
SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR
DISBURSEMENTS RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE
AGENT AS THE ISSUER OF A LETTER OF CREDIT. THE AGREEMENTS IN
THIS SECTION 2.1(J) SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL
OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT. 
 2.2 Limitations on Interest Periods. Each Interest Period selected by the Borrower (a) which commences on the last Business Day of a calendar month (or 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, if such next succeeding Business Day falls in the next succeeding calendar month, on the next preceding Business Day), (c) which would otherwise end after the Commitment Termination Date shall end on the
Commitment Termination Date and (d) shall have a duration of not less than one month and, if any Interest Period would otherwise be a shorter period, the relevant Loan shall be a Base Rate Loan during such period. 

2.3 Limitation on Types of Loans. Anything herein to the contrary notwithstanding, no more than six separate LIBO Rate Loans shall
be outstanding at any one time, with, for purposes of this Section, all LIBO Rate Loans for the same Interest Period constituting one LIBO Rate 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 Agent determines (which determination shall be
conclusive, absent manifest error) 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 Agent determines (which
determination shall be conclusive, absent manifest error) 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 adequately cover the cost to the Lenders of making or maintaining such Loan for such Interest Period, 

  
 - 23 -








 
then the Agent shall give the Borrowers and the Lenders 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 Base Rate Loans into LIBO Rate Loans, and the Borrowers 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 a LIBO Rate Loan with
amounts and maturities for which quotations are provided, or convert such Loan into a Base Rate Loan in accordance with the provisions of Section 2.12. 
 2.4 Use of Loan Proceeds and Letters of Credit. 
 (a) Proceeds of all Loans

pay fees and expenses incurred in connection with this Agreement. 
 (b) Letters of Credit shall be issued solely for the
account of either or both of the Borrowers for general business purposes of either of the Borrowers or any of the Subsidiary Guarantors not otherwise prohibited under applicable provisions of this Agreement; provided, however, no
Letter of Credit may be used in lieu or in support of stay or appeal bonds. 
 2.5 Interest. Subject to applicable
provisions of this Agreement (including those of Section 2.17), (a) interest on Base Rate Loans shall accrue and be payable at a daily interest rate based on the per annum rate equal to the sum of the Adjusted Base Rate for each
relevant day plus the Applicable Margin for Base Rate Loans on such day, converted to a daily rate on the basis of a year of 365 or 366 days, as the case may be; provided, however, in no event shall such applicable rate exceed the
Highest Lawful Rate, with such rate being applied on the basis of actual days elapsed (including the first day, but excluding the last day) during the period for which interest is payable at the relevant rate, and (b) interest on LIBO Rate
Loans shall accrue during each relevant Interest Period and be payable at a daily interest rate based on the per annum rate equal to the Adjusted LIBO Rate on the first day of the relevant Interest Period plus the relevant Applicable Margin for LIBO
Rate Loans on such day, converted to a daily rate on the basis of a year of 360 days; provided, however, in no event shall such applicable rate exceed the Highest Lawful Rate, with such rate being applied on the basis of actual days

 - 24 -








 
extent permitted by applicable law, past due interest and fees, shall accrue at the Default Rate and shall be payable upon demand by the Agent at any time as to all or any portion of such
interest. 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 to, but not including, the date or
dates of repayment. 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) shall be
automatically converted into a Base Rate Loan on the last day of the then current Interest Period for such Loan or (if outstanding as a Base Rate Loan) shall remain as, or (if not then outstanding) shall be made as, a Base Rate Loan. 

2.6 Repayment of Loans and Interest. Accrued and unpaid interest on each outstanding Base Rate Loan shall be due and payable

Termination Date. At the time of making each payment hereunder or under the Notes, the Borrowers or one of them shall specify to the Agent the Loans or other amounts payable by the Borrowers hereunder to which such payment is to be applied. In the
event the Borrowers fail 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 discretion and in accordance with the terms hereof. 

2.7 Outstanding Amounts. (a) The outstanding principal balance of the Note of each Lender reflected by the notations of such
Lender on its records shall be deemed rebuttably presumptive evidence of the principal amount owing on such Note. The liability for payment of principal and interest evidenced by each Note 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. 
 (b) Unless
the Agent shall have been notified by a Lender or the Borrowers prior to the date on which any of them is scheduled to make payment to the Agent of (in the case of a Lender) the proceeds of a Loan to be made by such Lender hereunder or (in the case
of the Borrowers) a payment to the Agent for the account of the Agent or one or more of the Lenders hereunder (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that it does not
intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and, in reliance upon such assumption, may (but shall not be required to) make the amount thereof available to the intended recipient on
such date. If such Lender or either of the Borrowers, as the case may be, has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, repay to the Agent solely for its account the amount so made available
together with interest 

  
 - 25 -








 
thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to,
in the case of a Lender as recipient, the Federal Funds Rate or, in the case of either of the Borrowers as recipient, the Adjusted Base Rate plus the relevant Applicable Margin. 

2.8 Taxes and Time, Place and Method of Payments. 
 (a) All payments required pursuant to this Agreement or the Notes shall be made without set-off or counterclaim in Dollars and in immediately available funds free and clear of, and without deduction for,
any Indemnified Taxes or Other Taxes; provided, however that if either of the Borrowers shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased by the amount
(the “Additional Amount”) necessary so that after making all required deductions (including deductions applicable to additional sums described in this paragraph) the Agent or any Lender, as the case may be, receives an amount equal
to the sum it would have received had no such deductions been made, (ii) the relevant Borrower shall make such deductions and (iii) the relevant Borrower shall pay the full amount deducted to the relevant Governmental Authority in
accordance with applicable law. In addition, to the extent not paid in accordance with the preceding sentence, the Borrowers shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 

(b) SUBJECT TO THE PROVISIONS OF
SECTION 2.20, THE BORROWERS SHALL INDEMNIFY THE AGENT AND EACH LENDER
FOR INDEMNIFIED TAXES AND OTHER TAXES PAID BY SUCH PERSON, INCLUDING
ANY INDEMNIFIED TAXES OR OTHER TAXES ARISING FROM THE NEGLIGENCE, WHETHER
SOLE OR CONCURRENT, OF THE AGENT OR ANY LENDER; PROVIDED,
HOWEVER, THAT THE BORROWERS SHALL NOT BE OBLIGATED TO MAKE
PAYMENT TO THE AGENT OR ANY LENDER IN RESPECT OF PENALTIES, INTEREST
AND OTHER SIMILAR LIABILITIES ATTRIBUTABLE TO SUCH INDEMNIFIED TAXES OR OTHER
TAXES IF SUCH PENALTIES, INTEREST OR OTHER SIMILAR LIABILITIES ARE ATTRIBUTABLE
TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON SEEKING
INDEMNIFICATION. 
 (c) If a Lender or the Agent shall become aware that it is entitled to
claim a refund from a Governmental Authority in respect of Indemnified Taxes or Other Taxes paid by either of the Borrowers pursuant to this Section 2.8, including Indemnified Taxes or Other Taxes as to which it has been indemnified by
the Borrowers, or with respect to which either of the Borrowers has paid Additional Amounts pursuant to the Loan Documents, it shall promptly notify the Borrowers of the availability of such refund claim and, if the Lender or the Agent, as the case
may be, determines in good faith that making a claim for refund will not have an adverse effect to its taxes or business operations, shall, within ten days after receipt of a request by either of the Borrowers, make a claim to such Governmental
Authority for such refund at the expense of the Borrowers. If a Lender or the Agent receives a refund in respect of any Indemnified Taxes or Other Taxes paid by either of the Borrowers pursuant to the Loan Documents, it shall within 30 days from the
date of such receipt pay over such refund to the relevant Borrower (but only to the extent of Indemnified Taxes or Other Taxes paid pursuant to the Loan Documents, including indemnity payments made or Additional Amounts paid, by the relevant
Borrower under this Section 2.8 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all reasonable out of pocket expenses of such Lender or the Agent, as the case may be, and without interest (other than
interest paid by the relevant Governmental Authority with respect to such refund). 

  
 - 26 -








  
 (d) If any Lender or
the Agent is or becomes eligible under any applicable law, regulation, treaty or other rule to a reduced rate of taxation, or a complete exemption from withholding, with respect to Indemnified Taxes or Other Taxes on payments made to it or for its
benefit by either of the Borrowers, such Lender or the Agent, as the case may be, shall, upon the request, and at the cost and expense, of the relevant Borrower, complete and deliver from time to time any certificate, form or other document
requested by the relevant Borrower, the completion and delivery of which are a precondition to obtaining the benefit of such reduced rate or exemption, provided that the taking of such action by such Lender or the Agent, as the case may be, would
not, in the reasonable judgment of such Lender or the Agent, as the case may be, be disadvantageous or prejudicial to such Lender or the Agent, as the case may be, or inconsistent with its internal policies or legal or regulatory restrictions. For
any period with respect to which a Lender or the Agent, as the case may be, has failed to provide any such certificate, form or other document requested by either of the Borrowers, such Lender or the Agent, as the case may be, shall not be entitled
to any payment under this Section 2.8 in respect of any Indemnified Taxes or Other Taxes that would not have been imposed but for such failure. 
 (e) Each Lender organized under the laws of the United States, any State thereof or the District of Columbia (other than Lenders that are corporations or otherwise exempt from United States backup
withholding Tax) shall (i) deliver to the Borrower and the Agent, when such Lender first becomes a Lender, upon the written request of either or both of the Borrowers or the Agent, two original copies of United States Internal Revenue Form W-9
or any successor form, properly completed and duly executed by such Lender, certifying that such Lender is exempt from United States backup withholding Tax on payments of interest made under the Loan Documents and (ii) thereafter at each time
it is so reasonably requested in writing by either or both of the Borrowers or the Agent, deliver within a reasonable time two original copies of an updated United States Internal Revenue Service Form W-9 or any successor form thereto. 

(f) Each Lender that is organized under the laws of a jurisdiction other than the United States, any State thereof or the District of
Columbia (each such Lender, a “Foreign Lender”) that is entitled to an exemption from or reduction of withholding Tax under the laws of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a
party, with respect to payments under the Loan Documents shall deliver to the Borrowers and the Agent, but only at the written request of either or both of the Borrowers or the Agent, such properly completed and duly executed documentation
prescribed by applicable law or reasonably requested by either or both of the Borrowers or the Agent as will permit such payments to be made without withholding or at a reduced rate, unless in the good faith opinion of the Foreign Lender such
documentation would expose the Foreign Lender to any material adverse consequence or risk. Such documentation shall be delivered by each Foreign Lender on or before the date it becomes a Lender and, if required by law, on or before the date, if any,
such Foreign Lender changes its Applicable Lending Office by designating a different lending office with respect to its Loans. In addition, each Foreign Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form
previously delivered by such Foreign Lender. Each Lender (and, in the case of a Foreign Lender its lending office), represents that on the Closing Date, payments made hereunder by the Borrowers or the Agent to it would not be subject to United
States Federal withholding tax. 

  
 - 27 -








  
 (g) Notwithstanding
the provisions of subsection (a) above, the Borrowers shall not be required to indemnify any Foreign Lender or to pay any Additional Amounts to any Foreign Lender, in respect of United States federal withholding Tax pursuant to subsection
(a) above, (i) to the extent that the obligation to withhold amounts with respect to United States federal withholding tax existed on the date such Foreign Lender became a Lender; (ii) with respect to payments to a new Applicable
Lending Office with respect to a Loan, but only to the extent that such withholding tax exceeds any withholding tax that would have been imposed on such Lender had it not designated such new Applicable Lending Office; (iii) with respect to a
change by such Foreign Lender of the jurisdiction in which it is organized, incorporated, controlled or managed, or in which it is doing business, from the date such Foreign Lender changed such jurisdiction, but only to the extent that such
withholding tax exceeds any withholding tax that would have been imposed on such Lender had it not changed the jurisdiction in which it is organized, incorporated, controlled or managed, or in which it is doing business; or (iv) to the extent
that the obligation to indemnify any Foreign Lender or to pay such Additional Amounts would not have arisen but for a failure by such Foreign Lender to comply with the provisions of Section 2.8(f). 

(h) All payments by the Borrowers shall be deemed received on (i) receipt or (ii) the next Business Day following receipt if
such receipt is after 3:00 p.m., Central Standard or Central Daylight Savings Time, as the case may be, on any Business Day, and shall be made to the Agent at the Principal Office. Except as provided to the contrary herein, if the due date of any
payment hereunder or under any Note 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; provided, however, that in the case of any LIBO Rate Loan, if the result of such extension would be to extend such payment into another calendar month, then the relevant payment shall be due on the immediately preceding
Business Day. 
 2.9 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 the Facility Amounts of the Lenders at the request of the
Borrowers, as well as any subsequent increase in the sum of the Facility Amounts of the Lenders at the request of the Borrowers and with written agreement of the Agent and all the 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 of Commitment Fees shall be made to the Agent 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 to the Agent for the account of the Lenders pro rata in accordance with their respective shares of the Loan Balance, (v) each payment of interest on
Loans shall be made to the Agent for the account of the Lenders pro rata in accordance with their respective shares of the aggregate amount of interest due and payable to the Lenders and (vi) each payment by either of the Borrowers under
Commodity Hedge Agreements and Interest Rate Hedge Agreements with Approved Hedge Counterparties shall be made only to the Person or Persons entitled thereto. 

  
 - 28 -








  
 (b) The Agent shall
distribute all payments with respect to the Obligations under the Loan Documents promptly upon receipt in like funds as received to the Lenders and any Approved Hedge Counterparties entitled to participate in any relevant payment. In the event that
any payments made hereunder by the Borrowers on the Obligations under the Loan Documents at any particular time are insufficient to satisfy in full the Obligations under the Loan Documents 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 any other Obligations under the Loan Documents pro rata on
the basis of the ratio of the amount of all such Obligations under the Loan Documents owing to the Agent or the relevant Lender, as the case may be, to the total amount of the Obligations under the Loan Documents then owing and (iv) fourth to
cash collateralize the L/C Exposure in the manner provided in Section 2.11. 
 (c) If any Lender (for purposes of
this Section, a “Benefited Lender”) shall at any time receive any payment of all or part of its portion of the Obligations under the Loan Documents, 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
Benefited Lender shall purchase for cash from the other Lenders such portion of the Obligations under the Loan Documents 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 Benefited 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 Benefited 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 Borrowers agree that each such Lender so purchasing a
portion of the Obligations under the Loan Documents 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 either of the Borrowers to be applied to the Obligations under the Loan Documents, 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. 

2.10 Borrowing Base and Monthly Reduction Amount. 
 (a) The Borrowing Base as of the Closing Date is acknowledged by the Borrower, the Agent and the Lenders to be $40,000,000. Commencing on the first day of November, 2010 and continuing thereafter on the
first day of each calendar month through the Commitment Termination Date, the amount of the Borrowing Base then in effect shall be reduced by the Monthly Reduction Amount, which Monthly Reduction Amount as of the Closing Date is acknowledged to be
$0.00. 
 (b) The Borrowing Base and the Monthly Reduction Amount shall be redetermined, by the Agent, with the approval of the
Lenders as required pursuant to the provisions of Section 9.9 (semi-annually prior to the Commitment Termination Date, as soon as 

  
 - 29 -








 
practicable following each receipt of information supplied by the Borrower in compliance with the provisions of Section 5.4). In addition, the Agent, with the approval of the Lenders
as required pursuant to the provisions of Section 9.9, shall, in the normal course of business following a request of either or both of the Borrowers, redetermine the Borrowing Base and the Monthly Reduction Amount; provided,
however, the Agent and the Lenders shall not be obligated to respond to more than one such request annually. Notwithstanding the foregoing, the Borrowing Base in effect at any time shall be subject to reduction in accordance with applicable
provisions of Section 6.4 and the Agent, with the approval of the Lenders as required pursuant to the provisions of Section 9.9, may at its discretion and shall, upon request by the Required Lenders and with the approval of
the Lenders as required pursuant to the provisions of Section 9.9, redetermine the Borrowing Base and the Monthly Reduction Amount at any time; provided, however, the Agent and the Lenders shall not be entitled to more than
one such unscheduled redetermination annually. 
 (c) Upon each determination of the Borrowing Base and the Monthly Reduction
Amount, the Agent shall notify the Borrowers orally (confirming such notice promptly in writing) of such determination, and, subject to the operation of the Monthly Reduction Amount, the Borrowing Base and the Monthly Reduction Amount so
communicated to the Borrowers shall become effective upon such oral notification and shall remain in effect until the next subsequent determination of the Borrowing Base and the Monthly Reduction Amount. 

(d) The Borrowing Base shall represent the determination by the Agent and the Lenders, in accordance with the applicable definitions and
provisions herein contained and the customary lending practices of the Agent and the Lenders for loans of this nature (but taking into account floor and cap prices or other price protection under Commodity Hedge Agreements), of the value, for loan
purposes, of the Mortgaged Properties and any other Oil and Gas Properties of either of the Borrowers or any of their respective Domestic Subsidiaries acceptable to the Agent and the Lenders, subject, in the case of any increase in the Borrowing
Base, to the credit approval processes of the Agent and each of the Lenders. Furthermore, the Borrowers and the Guarantors acknowledge that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value),
which is acknowledged by the Borrowers and the Guarantors to be essential for the adequate protection of the Agent and the Lenders. 
 2.11 Mandatory Prepayments. If at any time, as a result of the second sentence of subsection (a) of Section 2.10, the sum of the Loan Balance and the L/C Exposure exceeds the
Commitment Amount then in effect, the Borrowers shall, within three Business Days of receipt of notice from the Agent of such occurrence, prepay such portion of the Loan Balance and/or, as provided below in this Section 2.11, provide
cash as Collateral so that the sum of the Loan Balance and the L/C Exposure does not exceed the Commitment Amount then in effect. If at any time, other than as a result of the second sentence of subsection (a) of Section 2.10, the
sum of the Loan Balance and the L/C Exposure exceeds the Commitment Amount then in effect (such excess, a “Deficiency”), the Borrower shall, at the option of the Borrower communicated to the Agent within 10 days of receipt of notice
from the Agent of such occurrence, (i) prepay the amount of the Deficiency in four substantially equal installment payments, each for application on the Loan Balance and then to provide cash as Collateral for the L/C Exposure in the manner


  
 - 30 -








 
provided below in this Section 2.11, the first of which being due on the thirtieth day following receipt by the Borrowers of the relevant notice from the Agent and the second, third
and fourth of which being due on the sixtieth, ninetieth and one hundred twentieth day, respectively, following receipt by the Borrowers of the relevant notice from the Agent, (ii) provide, within 30 days of such election by the Borrowers,
additional Collateral, of character and value satisfactory to the Required Lenders in their sole discretion, and/or cash as Collateral to secure the Obligations, by way of the execution and delivery to the Agent of Security Documents in form and
substance reasonably satisfactory to the Agent or (iii) affect any combination of the alternatives described in clauses (i) and (ii) of this sentence and acceptable to the Required Lenders in their sole discretion. Any prepayment
pursuant to the provisions of this Section 2.11 shall be without premium or penalty, except as provided in Section 2.18, and the amount of any such prepayment may be reborrowed if otherwise available to the Borrowers pursuant
to the terms of this Agreement. In the event that a mandatory prepayment is to be made under this Section 2.11 or under Section 6.4 and the Loan Balance is less than the amount required to be prepaid, the Borrowers shall
repay the entire Loan Balance and, in accordance with the provisions of the relevant Letter of Credit Applications executed by the Borrowers or otherwise to the 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 Commitment Amount. The cash deposited with the Agent in satisfaction of the requirement provided in this Section 2.11 shall be invested,
at the express direction of either of the Borrowers 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 relevant Borrower in cash or cash
equivalent investments offered by or through Amegy. 
 2.12 Voluntary Prepayments and Conversions of Loans. Subject to
applicable provisions of this Agreement, the Borrowers shall have the right at any time or from time to time to prepay Loans without prepayment penalty 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 Borrowers shall give the Agent notice of each such prepayment or conversion of (i) all or any portion of a LIBO Rate Loan no less than three Business Days prior to
prepayment or conversion and (ii) all or any portion of a Base Rate Loan no less than one Business Day prior to prepayment or conversion, (b) any prepayment of any LIBO Rate Loan shall be in an amount of at least equal to $10,000 and a
whole multiple of $5,000, (c) the Borrowers shall pay all accrued and unpaid interest on the amounts prepaid or converted, (d) no such prepayment or conversion shall serve to postpone the repayment when due of any Obligation or any
installments thereof and (e) the Borrowers shall reimburse each Lender for any losses, expenses or costs incurred by such Lender pursuant to prepayment or conversion of a Loan, or the failure of the Borrowers to make such prepayment or
conversion as provided in Section 2.18. Except as provided in the immediately preceding sentence, any prepayment pursuant to the provisions of this Section 2.12 shall be without premium or penalty and the amount of any such
prepayment may be reborrowed if otherwise available to the Borrowers pursuant to the terms of this Agreement. 
 2.13
Commitment Fees. In addition to interest on the Notes as provided herein and other fees payable hereunder, and to compensate the Lenders for maintaining funds available under the Facility, the Borrowers shall pay to the Agent, for the account
of the Lenders, in immediately available funds, for the calendar quarter ending on the last day of December, 2010 and for each calendar quarter thereafter during the Commitment Period and on the Commitment


  
 - 31 -








 
Termination Date, a fee equal to three hundred seventy five one-thousandths of one percent (0.375%), calculated on the basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed (including the first day, but excluding the last day), multiplied by the average daily amount of the Available Commitment during the relevant quarterly or shorter period, as the case may be. Commitment Fees shall be payable by the Borrowers
upon receipt of an invoice therefor or statement thereof delivered by the Agent and shall be past due if not paid within ten days of receipt of each such invoice or statement. 
 2.14 Engineering Fees. The Borrower shall pay Amegy, solely for its account, the fees and expenses of the independent petroleum engineer or firm of independent petroleum engineers engaged by Amegy,
as the Agent, for purposes of the preparation of Reserve Reports. 
 2.15 Additional Fees. In addition to interest on the
Notes as provided herein and other fees payable hereunder, and to compensate the Lenders for the costs of the extension of credit hereunder, the Borrowers shall pay to the Agent, for the account of the Lenders, on the Closing Date, in immediately
available funds, a fee in the amount of $300,000. Additionally, the Borrowers shall pay a fee to the Agent, for the account of the Lenders at any time the Borrowing Base is increased to an amount in excess of the highest Borrowing Base previously in
effect at any time under this Agreement equal to the greater of (a) seventy five one-hundredths of one percent (0.75%) of the amount of such increase and (b) $2,000. Furthermore, the Borrowers shall pay a fee to the Agent on the Closing
Date and each anniversary of the Closing Date, for its account, equal to $5,000 multiplied by the total number of Lenders existing at such time; provided, however, that in the event that Amegy is the sole Lender existing at such time,
such fee shall not apply. 
 2.16 Loans to Satisfy Obligations. Upon a Default, the Lenders may, but shall not be
obligated to, with five Business Days’ written notice to the Borrowers of their intent to do so, 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 or any of the Guarantors contained in this Agreement or any other Loan Document. Such Loans shall be evidenced by the Notes and shall bear interest at the Adjusted Base Rate plus the relevant Applicable Margin, subject, however, to the
provisions of Section 2.5 regarding the accrual of interest at the Default Rate in certain circumstances. 
 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 Borrowers agree 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, provided that the Agent or any 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 Agent and each 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 Agent or the relevant
Lender, if greater. 

  
 - 32 -








  
 (b) Notwithstanding
anything herein or in the Notes to the contrary, during any Limitation Period, the interest rate to be charged on amounts evidenced by the Notes held by any affected Lenders 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 on amounts evidenced by the Notes held by any affected Lenders shall remain at the Highest Lawful Rate until such time as there has been paid to each applicable Lender
(i) the amount of interest in excess of that accruing at the Highest Lawful Rate that such Lender 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 such Lender but for the effect of such Limitation Period. 
 (c) If, under any circumstances, the
aggregate amounts paid on the Notes 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 Borrowers stipulate
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 party receiving such excess 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 such party or notice thereof from the Borrower. In the event that the maturity of any Obligation is accelerated, by reason of an election by the Lenders or otherwise, or in the event of any required or permitted
prepayment, then the consideration constituting interest under applicable laws may never exceed that payable on the basis of the Highest Lawful Rate, and excess amounts paid which by law are deemed interest, if any, shall be credited by the Agent
and the Lenders on the principal amount of the Obligations, or if the principal amount of the Obligations shall have been paid in full, refunded to the Borrowers. 
 (d) All sums paid, or agreed to be paid, to the Agent and 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 2.18 (but without
duplication), the Borrowers shall pay to the Agent and each Lender from time to time such amounts as are necessary to compensate it for any actual and reasonable Additional Costs incurred by the Agent or such Lender. 

(b) Without limiting the effect of the other provisions of this Section 2.18 (but without duplication), the Borrowers shall pay to
each Lender from time to time on request such amounts as are necessary to compensate such Lender or such Lender’s holding company for any costs attributable to the maintenance by such Lender (or any Applicable Lending Office), pursuant to any
Regulatory Change, of capital in respect of its Commitment, such compensation to include an amount equal to any reduction of the rate of return on assets or equity of such 

  
 - 33 -








 
Lender or such Lender’s holding company (or any Applicable Lending Office) to a level below that which such Lender or such Lender’s holding company (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 2.18 (but without duplication), in the event that any Requirement of Law or Regulatory Change or the compliance by the Agent or any Lender 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 such Lender 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 Agent or such Lender of issuing or maintaining any Letter of Credit or obligation to issue Letters of Credit or any liability with respect to Letter of Credit Payments, or to reduce any
amount receivable in connection therewith, then upon demand by the Agent or such Lender, as the case may be, the Borrowers shall pay to the Agent or such Lender, from time to time as specified by the Agent or such Lender, additional amounts which
shall be sufficient to compensate the Agent or such Lender for such increased cost or reduced amount receivable. 
 (d) Without
limiting the effect of the other provisions of this Section 2.18 (but without duplication), the Borrowers shall pay to the Agent and each Lender such amounts as shall be sufficient in the reasonable opinion of the Agent and such Lender
to compensate them for any actual and reasonable loss, cost, or expense incurred by and as a result of: 
  

	 	(i)	any payment, prepayment or conversion by either or both of the Borrowers 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 either or both of the Borrowers to borrow a LIBO Rate Loan or to convert a Base Rate Loan into a LIBO Rate Loan on the date for such borrowing or
conversion specified in the relevant Borrowing Request, 

 such compensation to include 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 or converted for the period from the date of such payment, prepayment, conversion,
or failure to borrow or convert to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow or convert, the Interest Period for such Loan which would have commenced on the date of such failure to borrow
or convert) at the applicable rate of interest for such Loan provided for herein over (B) the interest component of the amount the Agent or such Lender would bid were it to bid at the commencement of such period in the London interbank market
for Dollar deposits of amounts comparable to such principal amount and maturities comparable to such period, as reasonably determined by the Agent or such Lender. 
 (e) Determinations by the Agent or any Lender for purposes of this Section 2.18 of the effect of any Regulatory Change on capital maintained, its costs or rate of return, its obligation to
make and maintain Loans, issuing or participating in Letters of Credit, or on 

  
 - 34 -








 
amounts receivable by it in respect of Loans, Letters of Credit or such other obligations, and the additional amounts required to compensate the Agent and such Lender under this
Section 2.18 shall be conclusive, absent manifest error, provided that such determinations are made on a reasonable basis. The Agent or the relevant Lender shall furnish the Borrowers with a certificate setting forth in reasonable
detail the basis and amount of Additional Costs or any other loss, cost or expense incurred as a result of any such event, and the statements set forth therein shall be conclusive, absent manifest error, provided that such determinations are made on
a reasonable basis. The Agent or the relevant Lender shall (i) notify the Borrowers, as promptly as practicable after the Agent or such Lender obtains knowledge of any Additional Costs or other sums payable pursuant to this Section 2.18
and determines to request compensation therefor, of any event occurring after the Closing Date which will entitle the Agent or such Lender to compensation pursuant to this Section 2.18; and (ii) designate a different Applicable
Lending Office for the Loans 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 Agent or such Lender, be disadvantageous to the Agent or such Lender.
If any Lender requests compensation from the Borrowers under this Section 2.18, the Borrowers may, after payment of all compensation then accrued and by notice to the Agent and such Lender, require that the Loans by such Lender of the
type with respect to which such compensation is requested be converted into Base Rate Loans in accordance with Section 2.12. Any compensation requested by the Agent or any Lender pursuant to this Section 2.18 shall be due and
payable within 30 days of receipt by the Borrower of any such notice. 
 (f) The Agent and the Lenders agree not to request, and
the Borrowers shall not be obligated to pay, any Additional Costs or other sums payable pursuant to this Section 2.18 unless similar Additional Costs and other sums payable are also generally assessed by the Agent or such Lender against other
customers similarly situated where such customers are subject to documents providing for such assessment. 
 2.19
Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to (a) honor its obligation to make LIBO Rate Loans, or (b) maintain LIBO Rate
Loans, then such Lender shall promptly notify the Agent and the Borrowers thereof. The obligation of such Lender to make LIBO Rate Loans and convert Base Rate Loans into LIBO Rate Loans shall then be suspended until such time as such Lender may
again make and maintain LIBO Rate Loans, and the outstanding LIBO Rate Loans of such Lender shall be converted into Base Rate Loans. 
 2.20 Replacement Lenders. (a) If any Lender has notified the Borrower of its incurring Additional Costs or any other loss, cost or expense under Section 2.18 or has invoked the
indemnification as to certain Taxes set forth in Section 2.8, the Borrowers may, unless such Lender has notified the Borrowers that the circumstances giving rise to such notice no longer apply, terminate, in whole but not in part, the
Commitment of such Lender (other than the Agent) (the “Terminated Lender”) at any time upon five Business Days’ prior written notice to the Terminated Lender and the Agent (a “Notice of Termination”).

 (b) In order to effect the termination of the Commitment of the Terminated Lender, the Borrowers shall (i) obtain an
agreement with one or more Lenders to increase their Commitments and/or (ii) request any one or more other banking institutions to become a 

  
 - 35 -








 
“Lender” in place and instead of such Terminated Lender and agree to accept a Commitment; provided, however, that such one or more other banking institutions are reasonably acceptable
to the Agent and become parties hereto by executing an Assignment Agreement (the Lenders or other banking institutions that agree to accept in whole or in part the Commitment of the Terminated Lender being referred to herein as the
“Replacement Lenders”), such that the aggregate increased and/or accepted Facility Amounts of the Replacement Lenders under clauses (i) and (ii) above equal the Facility Amount of the Terminated Lender. 

(c) The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the
“Termination Date”), the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its Commitment, and, if there will be more than one Replacement Lender, the portion of the Terminated Lender’s
Commitment to be assigned to each Replacement Lender. 
 (d) On the Termination Date, (i) the Terminated Lender shall by
execution and delivery of an Assignment Agreement assign its Commitment to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the portion of the Terminated Lender’s Commitment
to be assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders its Loans (if any) then outstanding pro rata as aforesaid, (ii) the Terminated Lender shall
endorse its Note, payable without recourse, representation or warranty to the order of the Replacement Lender or Replacement Lenders (pro rata as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Note held by
the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid principal amount thereof plus interest and fees accrued and unpaid to the Termination Date, (iv) the Replacement Lender or Replacement Lenders will thereupon (pro rata
as aforesaid) succeed to and be substituted in all respects for the Terminated Lender with like effect as if becoming a Lender pursuant to the terms of Section 9.1(b) and the Terminated Lender will have the rights and benefits of an
assignor under Section 9.1(b) and (v) the Terminated Lender shall have received payment of an amount equal to its Percentage Share of the Loan Balance and accrued interest thereon, accrued fees owed to it and all other amounts due
and owing to it hereunder and under the other Loan Documents (including any loss, cost or expense under Section 2.18 incurred up to, but not including, the Termination Date). To the extent not in conflict, the terms of
Section 9.1(b) shall supplement the provisions of this Section 2.20. 
 (e) Any Terminated Lender
(including the Agent in its capacity as a Lender and as Agent) shall reimburse the Borrowers for all reasonable and necessary fees and expenses of counsel to the Borrowers and, if required by the Replacement Lender or Replacement Lenders, of counsel
to the Replacement Lender or Replacement Lenders in connection with replacing such Terminated Lender with a Replacement Lender or Replacement Lenders. 
 2.21 Regulatory Change. In the event that by reason of any Regulatory Change or any other circumstance arising after the Closing Date affecting any Lender, such Lender (a) incurs Additional
Costs based on or measured by the excess above a level, as prescribed from time to time by any Governmental Authority with jurisdiction, of the amount of a category of deposits or other liabilities of such Lender 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 

  
 - 36 -








 
credit or other assets of such Lender 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 such Lender with notice to the Agent and the Borrowers, the obligation of such Lender to make LIBO Rate Loans and to convert Base Rate Loans into LIBO Rate Loans shall be suspended until such time as such Regulatory Change
or other circumstance ceases to be in effect, and all such outstanding LIBO Rate Loans shall be converted into Base Rate Loans. 

2.22 Letters in Lieu of Transfer Orders or Division Orders. The Agent agrees that none of the letters in lieu of transfer or
division orders provided pursuant to the provisions of Section 3.1(f) or Section 5.7 will be sent to the addressees thereof unless an Event of Default has occurred and is continuing, 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. 
 2.23 Power of
Attorney. Each of the Borrowers hereby designates the Agent as its agent and attorney-in-fact, to act in its name, place, and stead solely for the purpose of completing and, upon the occurrence and the continuance of an Event of Default,
delivering any and all of the letters in lieu of transfer or division orders delivered by the Borrower pursuant to the provisions of Section 3.1(f) or Section 5.7, including completing any blanks contained in such letters and
attaching exhibits thereto describing the relevant Collateral. Each of the Borrowers 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 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, the Lenders and any other Secured Creditors under the Loan
Documents with respect to the assignment of production proceeds under certain of the Security Documents and shall not impose any duty upon the Agent to exercise any such powers. The power of attorney under this Section 2.23 is expressly
limited to the rights and powers set forth herein and no additional rights or powers are herein created or implied. 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 either of the Borrowers or any other Person for any act or failure to act with respect to such powers, except for gross negligence or willful misconduct. 
 2.24 Security Interest in Accounts; Right of Offset. As security for the payment and performance of the Obligations, each of the Borrowers and the Guarantors hereby transfers, assigns and pledges
to the Agent, each Lender and each other Approved Hedge Counterparty (for the pro rata benefit of such Persons) and grants to the Agent, each Lender and each other Approved Hedge Counterparty (for the pro rata benefit of such Persons) a security
interest in all of its funds now or hereafter or from time to time on deposit with the Agent, such Lender or such other Approved Hedge Counterparty, with such interest of the Agent, the Lenders and the other Approved Hedge Counterparties to be
retransferred, reassigned, and/or released at the expense of the Borrowers upon payment in full and complete performance of all Obligations. All remedies as secured party or assignee of such funds shall be exercisable upon the occurrence of any
Event of Default, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof. Furthermore,
each of the Borrowers and the Guarantors 

  
 - 37 -








 
hereby grants to the Agent, each Lender and each other Approved Hedge Counterparty (for the pro rata benefit of such Persons) the right, exercisable at such time as any Obligation shall mature,
whether by acceleration of maturity or otherwise, of offset or banker’s lien against all of its funds now or hereafter or from time to time on deposit with the Agent, such Lender or such other Approved Hedge Counterparty, 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. 

ARTICLE III 

CONDITIONS 
 The obligations of the Agent and the Lenders to enter into this Agreement and to make Loans or issue or participate in, as the case may be, Letters of Credit are subject to the satisfaction of the
following conditions precedent: 
 3.1 Receipt of Loan Documents and Other Items. Neither the Lenders nor the Agent shall
have any obligation under this Agreement unless and until all matters incident to the consummation of the transactions contemplated herein shall be satisfactory to the Agent and the Lenders, and the Agent and, upon request, any Lender shall have

 ARTICLE VIII

 THE AGENT 
 8.1 Appointment. Each Lender hereby designates and appoints the Agent as the agent of such Lender under this Agreement and the other Loan Documents. The Agent shall also act hereunder as agent for
all Approved Hedge Counterparties. Each Lender authorizes the Agent, as the agent for such Lender, to take such action on behalf of such Lender under the provisions of this Agreement and the other Loan Documents and to exercise such powers and
perform such duties as are expressly delegated to the Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement or in any other Loan Document, the Agent shall not have any duties or responsibilities except those expressly set forth herein or in any other Loan Document or any fiduciary relationship with any Lender; and no implied covenants,
functions, responsibilities, duties, obligations, or liabilities on the part of the Agent shall be read into this Agreement or any other Loan Document or otherwise exist against the Agent. 

8.2 Delegation of Duties. The Agent may execute any of its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Agent shall not be responsible to any Lender for the negligence or misconduct of any agents or attorneys-in-fact selected by
it with reasonable care. 
 8.3 Exculpatory Provisions. Neither the Agent nor any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates shall be (a) required to initiate or conduct any litigation or collection proceedings hereunder, except with the contribution by each Lender of its Percentage Share of 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 or any other Approved Hedge Counterparty for any recitals, statements, representations or warranties made by either of the Borrowers or any of the Guarantors
or any officer or representative 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 either of the Borrowers or any of the Guarantors to
perform its obligations hereunder or thereunder. The Agent shall not be under any obligation to any Lender or any other Approved Hedge Counterparty 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 either of the Borrowers or any of the Guarantors. 
 8.4 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 

  
 - 63 -








 
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 either of the Borrowers or any of the Guarantors), 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 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. 

8.5 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, either of the Borrowers or any of the Guarantors 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. 

8.6 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 either of the Borrowers or any of the Guarantors, 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 Borrowers and the Guarantors and the value of the Collateral and other Properties of either of the Borrowers, any of the Guarantors or any other Person 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 

  
 - 64 -








 
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 Borrowers and the Guarantors and the value of
the Collateral and other Properties of either of the Borrowers, any of the Guarantors or any other Person. 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 Borrowers and the Guarantors or the value of
the Collateral or other Properties of either of the Borrowers, any of the Guarantors or any other Person which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

 8.7 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
BORROWERS OR ANY OF THE GUARANTORS AND WITHOUT LIMITING THE OBLIGATION
OF THE BORROWERS AND THE GUARANTORS 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 8.7
SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE
TERMINATION OF THIS AGREEMENT. 
 8.8
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 either of the Borrowers or any of the Guarantors 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 

  
 - 65 -








 
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 either of the Borrowers or any of the Guarantors. 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 relevant Borrower or the relevant Guarantor 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 either of the Borrowers or any of the Guarantors 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 relevant Borrower or relevant Guarantor is made by the Agent (or the Lender required to return funds to the relevant Borrower or relevant Guarantor, 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 relevant Borrower or relevant Guarantor shall have made its ratable share of such funds available. 

8.9 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 any of the Borrower and the Guarantors 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. 

8.10 Successor Agent. The Agent may resign as Agent upon ten days’ notice to the Lenders, all Approved Hedge Counterparties
under then existing Commodity Hedge Agreements or Interest Rate Hedge Agreements and the Borrower. If the Agent shall resign as Agent under this Agreement and the other Loan Documents, Lenders (other than the Agent in its capacity as a Lender) for
which the Percentage Shares aggregate at least fifty-one percent (51%) of the Percentage Shares of all Lenders (other than the Agent in its capacity as a Lender) shall appoint from among the Lenders a successor agent for the Lenders and the
Approved Hedge Counterparties, whereupon such successor agent shall succeed to the rights, powers and duties of the Agent; provided, however, should the Agent resign at a point when all Loans, accrued interest and fees hereunder have been paid in
full and the Commitments have terminated, resulting in the only then existing Obligations being the liability of either of the Borrowers or any of the Guarantors under Commodity Hedge Agreements and/or Interest Rate Hedge Agreements with Approved
Hedge Counterparties, the successor agent shall be selected from among such Approved Hedge Counterparties by majority vote of such Approved Hedge Counterparties. 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 5.16, Section 5.17, Section 5.21 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. 

  
 - 66 -








  
 8.11 Applicable
Parties. The provisions of this Article are solely for the benefit of the Agent and the Lenders, and neither the Borrower nor any Guarantor shall 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 any other Approved Hedge Counterparties and does not assume, nor shall it be deemed to have assumed,
any obligation or relationship of trust or agency with or for either of the Borrowers or any of the Guarantors or any legal representative, successor or assign of any such Person. 

8.12 Releases. Each Lender hereby authorizes the Agent to release any Collateral that is permitted to be sold or released pursuant
to the terms of the Loan Documents. Each Lender hereby authorizes the Agent to execute and deliver to either of the Borrowers or any of the Guarantors, at the sole cost and expense of such Person, any and all releases of Liens, termination
statements, assignments or other documents reasonably requested by either of the Borrowers or any of the Guarantors in connection with any sale or other disposition of Property or any Domestic Subsidiary of GAM, GPC or any of their respective
Subsidiaries to the extent such sale or other disposition is permitted by the terms of the Loan Documents. 
 ARTICLE IX

 MISCELLANEOUS 
 9.1 Assignments; Participations. (a) Neither the Borrower nor any of the Guarantors may assign any of its rights or delegate any of its obligations under any Loan Document without the prior
consent of the Agent and the Lenders. 
 (b) With the consent of the Agent and, except when a Default or an Event of Default
shall have occurred and is continuing, the Borrowers, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement pursuant to an Assignment Agreement; provided, however,
(i) such consents shall not be required with respect to an assignment from one Lender to one or more other Lenders or Affiliates of Lenders, (ii) the consent of the Borrowers shall not be required with respect to an assignment from a
Lender to one or more Approved Funds or Affiliates of Approved Funds and (iii) any such assignment shall be in the amount of at least $5,000,000 (or any whole multiple of $1,000,000 in excess thereof), unless the relevant assignment is to an
Affiliate of the assigning Lender or is an assignment of the entire Commitment of the assigning Lender. The assignee shall pay to the Agent a transfer fee in the amount of $5,000 for each such assignment. Any such assignment shall become effective
upon the execution and delivery to the Agent of an Assignment Agreement and, if required, the consent of the Agent and the Borrowers. Promptly following receipt of an executed Assignment Agreement, the Agent shall send to the Borrowers a copy of
such executed Assignment Agreement. Promptly following receipt of such executed Assignment Agreement, the Borrowers shall execute and deliver, at their own expense, a new Note to the assignee, if such assignee is not then a Lender. Upon the
effectiveness of any assignment pursuant to this Section 9.1(b), the assignee will become a “Lender,” if not already a “Lender,” for all purposes of the Loan Documents, and the assignor shall be relieved of its
obligations hereunder to the extent of such assignment. If the assignor no longer holds any rights or obligations under this Agreement, such assignor shall cease to be a “Lender” hereunder, except


  
 - 67 -








 
that its rights under Section 5.17, Section 5.21 and Section 5.22, shall not be affected. On the last Business Day of each month during which an assignment has
become effective pursuant to this Section 9.1(b) or sooner following an assignment, the Agent shall prepare a new Exhibit IV giving effect to all such assignments effected during such month or any relevant assignment, as the case
may be, and will promptly provide a copy thereof to the Borrowers and each Lender. 
 (c) Each Lender may transfer, grant, or
assign participations in all or any portion of its interests hereunder to any Person pursuant to this Section 9.1(c), provided that such Lender shall remain a “Lender” for all purposes of this Agreement and the
transferee of such participation shall not constitute a “Lender” hereunder. In the case of any such participation, the participant shall not have any rights under any Loan Document, the rights of the participant in respect of such
participation to be against the granting Lender as set forth in the agreement with such Lender creating such participation, and all amounts payable by the Borrowers hereunder shall be determined as if such Lender had not sold such participation.
Each agreement creating a participation must include an agreement by the participant to be bound by the provisions of Section 8.3, Section 8.6 and Section 8.7. 

(d) The Lenders may furnish any information concerning either of the Borrowers or any of the Guarantors in the possession of the Lenders
from time to time to assignees and participants and prospective assignees and participants. 
 (e) Notwithstanding anything in
this Section 9.1 to the contrary, any Lender may assign and pledge all or any of its Notes or any interest therein to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve System and/or such Federal Reserve Bank. No such assignment or pledge shall release the assigning or pledging Lender from its obligations hereunder.

 (f) Notwithstanding any other provisions of this Section, no transfer or assignment of the interests or obligations of any
Lender or grant of participations therein shall be permitted if such transfer, assignment, or grant would require the Borrower to file a registration statement with the Securities and Exchange Commission or any successor Governmental Authority or
qualify the Loans under the “Blue Sky” laws of any state. 
 9.2 Survival of Representations, Warranties, and
Covenants. All representations and warranties of the Borrowers and the Guarantors and all covenants and agreements of the Borrowers and the Guarantors herein made shall survive the execution and delivery of the Notes and the Security Documents
and shall remain in force and effect so long as any Obligation is outstanding or any Commitment exists.

 9.5 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 Borrowers under this Agreement, the Notes, or any other Loan Document. 
 9.6 Rights of Third Parties. All provisions
herein are imposed solely and exclusively for the benefit of the Agent, the Lenders, any other Approved Hedge Counterparties, the Borrowers and the Guarantors. No other Person shall have any right, benefit, priority, or interest hereunder or as a

 9.7 No Waiver;
Rights Cumulative. No course of dealing on the part of the Agent or the Lenders or their officers or employees, nor any failure or delay by the Agent or the Lenders with respect to exercising any of their rights under any Loan Document shall
operate as a waiver thereof. The rights of the Agent and the Lenders 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 any Letter of Credit shall constitute a waiver of any of the covenants, warranties or conditions of either of the Borrowers or any of the Guarantors contained herein. In the event either of the Borrowers or any of the
Guarantors is unable to satisfy any such covenant, warranty or condition, neither the making of any Loan nor the issuance of any Letter of Credit shall have the effect of precluding the Agent or the Lenders 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. Subject to the preceding sentence, any provision of this Agreement or any other Loan Document may be
amended, modified or waived by the Borrowers, the Guarantors and the Required Lenders; provided that, notwithstanding any provision of this Agreement to the contrary, (a) no amendment, modification or waiver which extends the final maturity of
the Loans, increases the Commitment Amount, increases, affirms or reduces the Borrowing Base or the Monthly Reduction Amount, forgives the principal amount of any Indebtedness of the Borrowers outstanding under this Agreement or interest thereon or
fees owing under this Agreement or any other Loan Document, releases any guarantor of such Indebtedness, releases all or substantially all of the Collateral, reduces the interest rate applicable to the Loans or the fees payable to the Lenders
generally, affects Section 2.1, Section 2.2, Section 7.2(c) or this Section 9.9, modifies the definition of “Required Lenders” or postpones the date of payment of any amount due as a result
of the Monthly Reduction Amount or any fee payable hereunder or under any other Loan Document shall be effective without the consent of each Lender effected thereby; (b) no amendment, modification or waiver which increases the Facility Amount
or the 

  
 - 70 -








 
Percentage Share of any Lender shall be effective without the consent of such Lender; and (c) no amendment, modification or waiver which modifies the rights, duties or obligations of the
Agent shall be effective without the consent of the Agent. 
 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 Documents, but
subject to applicable provisions of this Agreement, 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 Documents or otherwise existing at law or in equity. 

9.12 Governing Law. THIS AGREEMENT AND THE NOTES
SHALL BE DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF
TEXAS, WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF RELATING TO CONFLICTS OF
LAW. 
 9.13 Waiver of Right to Jury Trial. EACH OF
THE BORROWERS, THE GUARANTORS, THE AGENT AND THE LENDERS HEREBY KNOWINGLY,
VOLUNTARILY, INTENTIONALLY, IRREVOCABLY AND UNCONDITIONALLY WAIVES ALL RIGHTS TO TRIAL
BY JURY IN ANY ACTION, SUIT, PROCEEDING, COUNTERCLAIM OR OTHER LITIGATION
THAT RELATES TO OR ARISES OUT OF THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT OR THE ACTS OR OMISSIONS OF THE AGENT OR ANY
LENDER IN THE ENFORCEMENT OF ANY OF THE TERMS OR PROVISIONS OF
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR OTHERWISE WITH RESPECT
THERETO. THE PROVISIONS OF THIS SECTION 9.13 ARE A MATERIAL INDUCEMENT
FOR THE AGENT AND EACH OF THE LENDERS TO ENTER INTO THIS
AGREEMENT. 
 9.14 Waiver of Class Action. EACH OF
THE BORROWER AND THE GUARANTORS WAIVES THE RIGHT TO LITIGATE ANY
CLAIM, DISPUTE OR CONTROVERSY WITH RESPECT TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT AS A CLASS ACTION, EITHER AS A MEMBER OF
A CLASS OR AS A REPRESENTATIVE, OR TO ACT AS A PRIVATE
ATTORNEY GENERAL. 
 9.15 Jurisdiction and Venue. ALL
ACTIONS OR PROCEEDINGS WITH RESPECT TO, ARISING DIRECTLY OR INDIRECTLY IN
CONNECTION WITH, OUT OF, RELATED TO OR FROM THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT MAY BE LITIGATED, AT THE SOLE DISCRETION AND
ELECTION OF THE AGENT, IN COURTS HAVING SITUS IN HOUSTON, HARRIS
COUNTY, TEXAS. IN SUCH REGARD, EACH OF THE BORROWERS AND THE
GUARANTORS 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

 9.16
Integration. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS CONSTITUTE THE ENTIRE
AGREEMENT AMONG THE PARTIES HERETO AND THERETO WITH RESPECT TO THE
SUBJECT HEREOF AND THEREOF AND SHALL SUPERSEDE ANY PRIOR AGREEMENT AMONG
THE PARTIES HERETO AND THERETO, WHETHER WRITTEN OR ORAL, RELATING TO
THE SUBJECT HEREOF AND THEREOF, INCLUDING ANY TERM SHEET PROVIDED TO
THE BORROWERS BY THE AGENT OR ANY LENDER. FURTHERMORE, IN THIS
REGARD, THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS REPRESENT, COLLECTIVELY,
THE FINAL AGREEMENT AMONG THE PARTIES THERETO AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF
SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG SUCH
PARTIES. 
 9.17 Waiver of Punitive and Consequential Damages. EACH
OF THE BORROWERS AND THE GUARANTORS, THE AGENT AND THE LENDERS HEREBY
KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY (A) WAIVES, TO THE MAXIMUM
EXTENT IT MAY LAWFULLY AND EFFECTIVELY DO SO, ANY RIGHT IT MAY
HAVE TO CLAIM OR RECOVER, IN ANY DISPUTE BASED HEREON, OR DIRECTLY
OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION
WITH THE LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED
THEREWITH, BEFORE OR AFTER MATURITY, ANY SPECIAL, EXEMPLARY, PUNITIVE OR
CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL
DAMAGES AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER
INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED
HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS SECTION 9.17. 
 9.18 Counterparts. For the convenience of the parties, this Agreement may be executed in multiple counterparts and by different parties hereto in separate counterparts, each of which for all
purposes shall be deemed to be an original, and all such counterparts shall together constitute but one and the same Agreement and shall be enforceable as of the date hereof upon the execution of one or more counterparts hereof by each of the
parties hereto. In this regard, each of the parties hereto acknowledges that a counterpart of this Agreement containing a set of counterpart execution pages reflecting the execution of each party hereto shall be sufficient to reflect the execution
of this Agreement by each party hereto and shall constitute one instrument. 
 9.19 USA Patriot Act Notice. Each Lender
and the Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers and the Guarantors that, pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies the
Borrowers and the Guarantors, which information includes the name and address of the Borrower’s and the Guarantors and other information that will allow such Lender or the Agent, as applicable, to identify the Borrowers and the Guarantors in
accordance with the USA Patriot Act. 
 9.20 Contribution and Indemnification. In the event that any Credit Party pays
(whether through direct payments or as a result of providing Collateral for the Obligations) any amounts on the Obligations in excess of such Credit Party’s Obtained Benefit (the “Excess Payments”), such Credit Party shall be
entitled to make demand on the other Credit Parties for such Excess Payments, and to receive from each other Credit Party that received an Obtained Benefit, such Credit Party Contribution Percentage of the Excess Payment. If any party


  
 - 72 -








 
obligated to make such a payment is unable to pay the Contribution Percentage of the Excess Payment, each other Credit Party agrees to make a contribution to the party entitled to such payment to
the extent necessary so that each Credit Party shares equally the liability for such Excess Payment in relation to the relative Obtained Benefit received by such Credit Party. IN SUCH REGARD,
TO THE MAXIMUM EXTENT PERMITTED BY LAW, EACH CREDIT PARTY SHALL
INDEMNIFY, DEFEND AND HOLD HARMLESS THE OTHER CREDIT PARTIES FROM AND
AGAINST ANY AND ALL LIABILITY, CLAIMS, COSTS AND EXPENSES (INCLUDING REASONABLE
ATTORNEYS’ FEES AND EXPENSES) ARISING WITH RESPECT TO THE OBLIGATIONS AND
EXCEEDING SUCH OTHER CREDIT PARTY’S OBTAINED BENEFIT OR CONTRIBUTION PERCENTAGE
THEREOF AS PROVIDED HEREIN. Any amount due under this Section 9.20 shall be due and payable within ten days of demand therefor by the party entitled to
payment and shall be made to the party entitled thereto at the address for notices to the Credit Parties under this Agreement, in immediately available funds, not later than 2:00 p.m., Central Standard or Daylight Time, on the date on which such
payment shall come due. The remedies available to any Credit Party pursuant to the provisions of this Section 9.20 are not exclusive. All rights and claims of contribution, indemnification and reimbursement under this
Section 9.20 shall be subordinate in right of payment to the prior payment in full of the Obligations. The provisions of this Section 9.20 shall, to the extent expressly inconsistent with any provision in any Loan Document,
supersede such inconsistent provision. 
 9.21 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 one or more of the Lenders may treat its 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, such Lender or Lenders, as applicable, will maintain the lists and other records required, if any, by such Treasury Regulations. 

9.22 Release of Liens. Upon the termination of all Commitments and payment by the Borrowers of the Obligations in full, Amegy, in
its capacity as collateral agent, will execute and deliver any termination statements, lien releases, discharges of security interests and mortgages and other similar discharge or release documents (and, if applicable, in recordable form) as are
reasonably necessary to release, as of record, all Liens and all notices of security interests, mortgages and liens previously filed on the Collateral with respect to the Obligations. 

9.23 Confidentiality. 
 (a) Each of the Agent and the Lenders agrees that it shall use its best efforts in good faith to hold in confidence and not disclose to any third party any material, non-public information regarding the
Borrowers and any Subsidiaries, their operations, assets and existing and contemplated business plans or any other written information and materials that is marked “Confidential” and is provided by the Borrowers to any Lender or the Agent
(collectively, the “Confidential Information”). 

  
 - 73 -








  
 (b) Notwithstanding
the foregoing paragraph (a), this Section 9.23 shall not apply to (i) exchanges of Confidential Information among the Agent and the Lenders themselves and the furnishing of Confidential Information by the Agent and the Lenders to
employees, officers, attorneys, accountants, auditors, and other consultants; provided, however, any such consultant shall have first agreed to treat such Confidential Information as confidential as provided in this
Section 9.23, (ii) Confidential Information that has been or is made public by the Borrowers or any third party without breach of this Agreement or otherwise becomes generally available to the public other than as a result of
prohibited disclosure in violation of this Section 9.23, (iii) Confidential Information that was or becomes available to the Agent or the Lenders from a third party on a non-confidential basis, (iv) information required to be
disclosed by regulatory authorities, so long as such authorities are informed of the confidential nature of such information (v) Confidential Information required to be disclosed by statute, decision or judicial or administrative order, rule or
regulation; provided that (x) prior to any disclosure under this clause (v), the disclosing party agrees to provide the Borrowers with prior notice thereof, to the extent that it is practicable to do so and to the extent that the
disclosing party is permitted to provide such prior notice to the Borrowers pursuant to the terms of the applicable statute, decision or judicial or administrative order, rule or regulation and (y) any disclosure under this clause
(v) shall be limited to the portion of the Confidential Information as may be required by such statute, decision or judicial or administrative order, rule or regulation or (vi) any disclosure of Confidential Information in connection with
any assignment, participation or pledge of any Lender’s interest under this Agreement, provided that any such assignee, participant or pledgee shall have agreed in writing to receive such information hereunder subject to the terms of
this Section 9.23.

 Amegy Bank National Association,

Parkway, 4th Floor 

Houston, Texas 77027 
 Attention: Energy Lending
Dept. 
  

	 	Re:	Second Amended and Restated Credit Agreement dated as of October 1, 2010 by and among Contango Oil & Gas Company, a Delaware corporation
(“Contango O&G”), Contango Operators, Inc., a Delaware corporation (“Contango Operators”), the lenders signatory thereto or bound thereby from time to time (the “Lenders”) and Amegy Bank
National Association, a national banking association, as Agent (“Amegy”) (as amended, supplemented, restated or otherwise modified from time to time, the “Credit Agreement”) 


Ladies and Gentlemen: 
 [We][I]
have acted as counsel to Contango O&G and Contango Operators (collectively, the “Credit Parties”) in connection with the transactions contemplated in the Credit Agreement. This opinion is delivered pursuant to
Section 3.1(o) of the Credit Agreement, and the Agent and the Lenders are hereby authorized to rely upon this opinion in connection with the transactions contemplated in the Credit Agreement. For convenience, each capitalized term used but not
defined herein shall have the meaning assigned to such term in the Credit Agreement, unless expressly provided to the contrary herein. 
 In [our][my] representation of the Credit Parties, [we][I] have examined an executed counterpart or a copy of an executed counterpart of each of the following (collectively, the “Loan
Documents”), each of which is dated of even date herewith: 
 (i) the Credit Agreement; 

(ii) the Note in effect on the Closing Date; 

(iii) Act of Assignment of Note, Mortgage Liens, Security Interests and Other Rights (the “Assignment”)
among Compass Bank, an Alabama banking association (“Compass”) and successor in interest to Guaranty Bank, FSB, for itself and as Administrative Agent, Amegy, for itself and as Agent and Collateral Agent, Contango O&G and
Contango Operators; 

  
 Exhibit V-i








  
 (iv)
Act of Second Amended and Restated Mortgage, Pledge, Security Agreement and Assignment of Production (the “Mortgage”) from Contango Operators in favor of Amegy, as collateral agent (in such capacity, the “Collateral
Agent”); and 
 (v) Second Amended and Restated Security Agreement (the “Security
Agreement”) from the Credit Parties, as Debtors, in favor of the Collateral Agent, as Secured Party. 
 [We][I] have
also examined copies of (a) a UCC Financing Statement reflecting Contango Operators as the Debtor and the Collateral Agent as the Secured Party to be filed in any parish in the State of Louisiana (the “Louisiana Financing
Statement”) and (b) UCC Financing Statements reflecting Contango O&G and Contango Operators, respectively, as the Debtor and the Collateral Agent as the Secured Party to be filed with the Secretary of State of the State of Delaware
(the “Delaware Financing Statements”). 
 In making such examinations, [we][I] have, with your permission,
assumed: 
 (i) the genuineness of all signatures to the Loan Documents other than those of officers of the
Credit Parties; 
 (ii) the authenticity of all documents submitted to [us][me] as originals and the conformity
with the originals of all documents submitted to [us] [me] as copies; 
 (iii) that each of Compass and Amegy is
duly organized, legally existing and in good standing under the laws of its jurisdiction of organization; 
 (iv)
that each of Compass, for itself and as Administrative Agent, and Amegy, for itself and as the Agent and the Collateral Agent, is authorized and has the power to enter into and perform its obligations under those of the Credit Agreement, the other
Loan Documents and the Assignment to which it is a party; and 
 (v) the due authorization, execution and
delivery of all Loan Documents by each party thereto other than the Credit Parties. 
 Based upon the foregoing and subject to
the qualifications set forth herein, [we are][I am] of the opinion that: 
 1. Each of the Credit Parties is a corporation duly
organized, legally existing and in good standing under the laws of the State of Delaware and is duly qualified and in good standing as a foreign corporation in each other state of the United States in which its owns property or conducts business,
unless a failure to be so qualified and in good standing could not reasonably be expected to have a Material Adverse Effect. 

2. The execution and delivery by each of the Credit Parties of the Credit Agreement and the borrowings and obtaining of Letters of Credit
by the Credit Parties thereunder, the execution and delivery by each of the Credit Parties of the other Loan Documents to which such Credit Party is a party and the Assignment, and the payment and performance by the Credit Parties of all Obligations

any Property of such Credit Party may be presently bound or encumbered or (d) result in or require the creation or imposition of any Lien upon any Property of such Credit Party other than as contemplated by the Assignment or the Loan Documents.

 3. The Assignment and the Loan Documents to which any of the Credit Parties is a party constitute legal, valid and binding
obligations of such Credit Party enforceable against such Credit Party in accordance with their respective terms. 
 4. The form
of each of the Assignment and the Mortgage and the forms of the descriptions in the Mortgage of the Mortgaged Property (as defined therein) satisfy all applicable laws of the State of Texas or the State of Louisiana, as applicable, and are legally
sufficient under the laws of the State of Texas or the State of Louisiana, as applicable, to enable Amegy, the Agent or the Collateral Agent, as the case may be, to realize the practical benefits purported to be afforded by the Assignment or the
Mortgage, as the case may be. 
 5. Each of the Assignment and the Mortgage is in satisfactory form for filing and recording in
the offices described in paragraph 9 hereof. 
 6. The Mortgage (a) creates liens upon and security interests in all
Mortgaged Property (as defined therein) to secure the Secured Indebtedness (as defined therein) and (b) provides for nonjudicial foreclosure remedies customarily used in the State of Louisiana. 

7. The Security Agreement creates security interests in all Collateral (as defined therein) to secure the Secured Obligations (as defined
therein). 
 8. The form of the Louisiana Financing Statement satisfies all applicable requirements of the Uniform Commercial
Code in effect in the State of Louisiana (the “Louisiana UCC”) and is legally sufficient under the Louisiana UCC to enable the Collateral Agent to realize the practical benefits purported to be afforded by the Mortgage as to that
portion of the Mortgaged Property as to which perfection of a security interest therein is accomplished by the filing of a UCC Financing Statement in any parish in the State of Louisiana. The form of each of the Delaware Financing Statements
satisfies all applicable requirements of the Uniform Commercial Code in effect in the State of Delaware (the “Delaware UCC”) and is legally sufficient under the Delaware UCC to enable the Collateral Agent to realize the practical
benefits purported to be afforded by the Security Agreement as to the Collateral provided by the Credit Parties thereunder as to which perfection of security interests therein is accomplished by the filing of a UCC Financing Statement. 

9. A fully executed counterpart of the Assignment should be filed with the parish clerk of each parish in the State of Louisiana in or

 Exhibit V-iii








 
Management Service, Gulf of Mexico Division in New Orleans, Louisiana [and in the State of Louisiana State Lands Office]. A counterpart of the Louisiana Financing Statement should be filed

of each parish in the State of Louisiana in or offshore from which any portion of the Mortgaged Property (as defined in the Mortgage) is located, in the office of the United States Department of the Interior, Minerals Management Service, Gulf of
Mexico Division in New Orleans, Louisiana [and in the State of Louisiana State of Lands Office] and the filing of a counterpart of the Delaware Financing Statement naming Contango Operators as the Debtor with the Secretary of State of the
State of Delaware are the only filings and/or recordings in the State of Louisiana or the State of Delaware necessary to perfect the liens and security interests created by the Mortgage or to permit the Collateral Agent to enforce its rights under
the Mortgage. The filings of the Delaware Financing Statements with the Secretary of State of the State of Delaware are the only filings under the Delaware UCC necessary to perfect the security interests created by the Security Agreement as to the
Collateral thereunder as to which perfection of such security interests is accomplished by the filing of a UCC Financing Statement. 
 10. No state or local mortgage registration tax, stamp tax or other similar tax, fee or governmental charge (other than statutory filing fees to be paid upon filing) is required to be paid to the State of
Louisiana or any subdivision thereof in connection with the filing and/or recording of counterparts of the Mortgage as indicated above.

“affiliate person” of an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Law, the Delaware UCC and applicable United States federal law.
