Agent”).
Recitals
A.    Borrower, Administrative Agent and the Lenders are parties to that certain
Credit Agreement dated as of September 2, 2014 (as heretofore amended, modified,
supplemented or restated, the “Credit Agreement”), pursuant to which the Lenders
have, subject to the terms and conditions set forth therein, made certain credit
available to and on behalf of Borrower.
B.    The parties hereto desire to enter into this Eighth Amendment to amend the
Credit Agreement as set forth herein.
C.    Borrower has requested that IBERIABANK (the “Additional Lender”) becomes a
Lender under the Credit Agreement with a Commitment in the amount shown on Annex
I to the Credit Agreement (as amended hereby).
D.    The Lenders party hereto also desire to complete the April 1, 2018
Scheduled Redetermination as set forth herein.
NOW, THEREFORE, in consideration of the premises and the mutual covenants herein
contained, for good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows:
Section 1.Defined Terms. Each capitalized term which is defined in the Credit
Agreement, but which is not defined in this Eighth Amendment, shall have the
meaning ascribed to such term in the Credit Agreement (as amended hereby).
Unless otherwise indicated, all section references in this Eighth Amendment
refer to the Credit Agreement.

Section 2.Amendments to the Credit Agreement. In reliance on the
representations, warranties, covenants and agreements contained in this Eighth
Amendment, and subject to the satisfaction of the conditions precedent set forth
in Section 6 hereof, the Credit Agreement is hereby amended, effective as of the
Eighth Amendment Effective Date, as follows:

2.1Amendments to Section 1.02.

(a)Each of the following definitions set forth in Section 1.02 is hereby amended
and restated in its entirety to read as follows:

“Maturity Date” means April 30, 2023.

1

--------------------------------------------------------------------------------

(b)Each of the following definitions is added to Section 1.02 in the appropriate
alphabetical order:

“Eighth Amendment Effective Date” shall mean April 30, 2018.
2.2Amendment to Section 2.07(e). Section 2.07(e) is hereby amended by replacing
the reference to “April 1, 2018” appearing in clause (y) of the third sentence
of Section 2.07(e) with “October 1, 2018”.

2.3Amendments to Section 3.03. Section 3.03 is hereby amended and restated in
its entirety to read as follows:

Section 3.03    Alternate Rate of Interest.
(a)    If prior to the commencement of any Interest Period for a Eurodollar
Borrowing:
(i)    the Administrative Agent or the Required Lenders determine (which
determination shall be conclusive absent manifest error) that, because of
changes arising on or after the Effective Date affecting the interbank LIBOR
market, adequate and reasonable means do not exist for ascertaining the Adjusted
LIBO Rate or the LIBO Rate for such Interest Period; or
(ii)    the Administrative Agent is advised by the Required Lenders that the
Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will
not adequately and fairly reflect the cost to such Lenders of making or
maintaining their Loans included in such Borrowing for such Interest Period;
then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone, email or fax as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective,
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made either as an ABR Borrowing or at an alternate rate of
interest determined by the Required Lenders in good faith as their cost of
funds.
(b)    Notwithstanding anything to the contrary set forth in the foregoing
clause (a), if at any time the Administrative Agent determines (which
determination shall be conclusive absent manifest error) that (i) the
circumstances set forth in clause (a)(i) have arisen and such circumstances are
unlikely to be temporary or (ii) the circumstances set forth in clause (a)(i)
have not arisen but the supervisor or the administrator of the LIBO Rate or the
LIBOR Market Index Rate or a Governmental Authority having jurisdiction over the
Administrative Agent has made a public statement identifying a specific date
after which the LIBO Rate or the LIBOR Market

2

--------------------------------------------------------------------------------

Index Rate shall no longer be used for determining interest rates for loans in
the syndicated loan market in the United States, then the Administrative Agent
and the Borrower shall endeavor in good faith to establish an alternate rate of
interest to the LIBO Rate and the LIBOR Market Index Rate that gives due
consideration to the then prevailing market convention for determining a rate of
interest for syndicated loans in the United States at such time, and shall enter
into an amendment to this Agreement to reflect such alternate rate of interest
and such other related changes to this Agreement as may be applicable.
Notwithstanding anything to the contrary in Section 12.02, such amendment shall
become effective without any further action or consent of any other party to
this Agreement so long as the Administrative Agent shall not have received,
within five Business Days of the date notice of such alternate rate of interest
is provided to the Lenders, a written notice from the Required Lenders stating
that such Required Lenders object to such amendment. Until an alternate rate of
interest shall be determined in accordance with this clause (b) (but, in the
case of the circumstances described in clause (ii) of the first sentence of this
Section 3.03(b), only to the extent the LIBO Rate for such Interest Period or
the LIBOR Market Index Rate for any Swingline Loan is not available or published
at such time on a current basis), (x) any Interest Election Request that
requests the conversion of any Borrowing to, or continuation of any Borrowing
as, a Eurodollar Borrowing shall be ineffective and (y) if any Borrowing Request
requests a Eurodollar Borrowing or a Swingline Loan, such Borrowing or Swingline
Loan shall be made as an ABR Borrowing; provided that, if such alternate rate of
interest shall be less than zero, such rate shall be deemed to be zero for the
purposes of this Agreement.
Section 3.Borrowing Base Redetermination. Subject to the satisfaction of the
conditions precedent set forth in Section 6 hereof, Administrative Agent and the
Lenders hereby agree that for the period from and including the Eighth Amendment
Effective Date to but excluding the next Redetermination Date, the amount of the
Borrowing Base shall be increased to $2,150,000,000 (the “April 2018
Redetermination”). Administrative Agent, the Lenders and Borrower agree that the
foregoing constitutes the April 1, 2018 Scheduled Redetermination and that this
Eighth Amendment shall constitute the New Borrowing Base Notice with respect to
such Scheduled Redetermination. Notwithstanding the foregoing, the Borrowing
Base may be subject to further redeterminations and adjustments from time to
time pursuant to Section 2.07 or Section 8.12(c).

Section 4.Increase of Aggregate Commitment. Subject to the satisfaction of the
conditions precedent set forth in Section 6 hereof:

4.1Each undersigned Increase Lender (each, an “Increasing Lender”) has agreed
(i) to increase its Commitment under the Credit Agreement effective as of the
Eighth Amendment Effective Date to the amount set forth opposite such Increasing
Lender’s name on Annex I attached hereto under the caption “Commitment” and (ii)
that it shall continue to be a party in all respects to the Credit Agreement and
the other Loan Documents pursuant to Section 2.10(a)(viii) of the Credit
Agreement.

3

--------------------------------------------------------------------------------

4.2The undersigned Additional Lender has agreed (i) to provide its Commitment
under the Credit Agreement effective as of the Eighth Amendment Effective Date
to the amount set forth opposite such Additional Lender’s name on Annex I
attached hereto under the caption “Commitment” and (ii) that it shall, as of the
Eighth Amendment Effective Date, be deemed a party in all respects to the Credit
Agreement and the other Loan Documents pursuant to Section 2.10(a)(viii) of the
Credit Agreement.

4.3The parties hereto hereby agree that this Eighth Amendment shall be deemed to
constitute a Commitment Increase Certificate for purposes of Section 2.10(a)(v)
of the Credit Agreement and an Additional Lender Certificate for purpose of
Section 2.10(a)(vi) of the Credit Agreement.

4.4On the Eighth Amendment Effective Date, Annex I to the Credit Agreement will
be replaced in its entirety with Annex I attached hereto pursuant to Section
2.10(a)(viii)(B).

4.5The parties hereto hereby agree the outstanding Revolving Loans, Swingline
Loans and LC Exposure will be reallocated by the Administrative Agent on the
Eighth Amendment Effective Date among the Lenders (including the Additional
Lender and the Exiting Lenders (as defined below)), in accordance with their
revised Applicable Percentages (or in the case of each Exiting Lender, adjusted
to equal $0.00), and the Lenders (including the Additional Lender, but excluding
the Exiting Lenders) shall make all payments and adjustments necessary to effect
such reallocation.

4.6Each Lender (including, for the avoidance of doubt, each undersigned Lender
that is not increasing its Commitment pursuant to Section 4.1 above and each
Exiting Lender) hereby agrees that the Borrower shall not be required to make
any break-funding payments which may otherwise be required under Section 5.02 of
the Credit Agreement solely resulting from the increase in the Commitments
effected pursuant to this Eighth Amendment; provided, that the Lenders’ waiver
of such break-funding payments set forth in this Section 4.6 is a limited,
one-time waiver, and nothing contained herein shall obligate the Administrative
Agent or any Lender to grant any additional or future waiver with respect to, or
in connection with, any provision of the Credit Agreement or any other Loan
Document.

Section 5.Additional Lender. The Additional Lender hereby joins in, becomes a
party to, and agrees to comply with and be bound by the terms and conditions of
the Credit Agreement as a Lender thereunder and under each and every other Loan
Document to which any Lender is required to be bound by the Credit Agreement, to
the same extent as if the Additional Lender were an original signatory thereto.
The Additional Lender hereby appoints and authorizes the Administrative Agent to
take such action as the Administrative Agent on its behalf and to exercise such
powers and discretion under the Credit Agreement as are delegated to the
Administrative Agent by the terms thereof, together with such powers and
discretion as are reasonably incidental thereto. The Additional Lender
represents and warrants that (a) it has full power and authority, and has taken
all action necessary, to execute and deliver this Eighth Amendment, to
consummate the transactions contemplated hereby and to become a Lender under the
Credit Agreement, (b) it has received a copy of the Credit Agreement and copies
of the most recent financial statements delivered pursuant to Section 8.01
thereof, and such other documents and information as it has deemed appropriate
to

4

--------------------------------------------------------------------------------

make its own credit analysis and decision to enter into this Eighth Amendment
and to become a Lender on the basis of which it has made such analysis and
decision independently and without reliance on the Administrative Agent or any
other Lender, and (c) from and after the Eighth Amendment Effective Date, it
shall be a party to and be bound by the provisions of the Credit Agreement and
the other Loan Documents and have the rights and obligations of a Lender
thereunder.

Section 6.Conditions Precedent. The effectiveness of this Eighth Amendment is

5

“hereof”, “herein”, or words of like import shall mean and be a reference to the
Credit Agreement, as amended hereby, and each reference to the Credit Agreement
in any other document, instrument or agreement executed and/or delivered in
connection with the Credit Agreement shall mean and be a reference to the Credit
Agreement, as amended hereby. The execution, delivery and effectiveness of this

parties hereto in any number of separate counterparts, and all of such

8.5Governing Law. This Eighth Amendment (including, but not limited to, the
validity and enforceability hereof) shall be governed by, and construed in
accordance with, the laws of the State of New York.

8.6Severability. Any provision of this Eighth Amendment which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

8.7Loan Document. This Eighth Amendment shall constitute a “Loan Document” for
all purposes under the other Loan Documents.
