1.6Amendment and Restatement of Section 12.19 of the Credit Agreement. Section
12.19 of the Credit Agreement is hereby amended and restated in its entirety to
read in full as follows:

Section 12.19    Acknowledgment Regarding Supported QFCs. To the extent that the
Loan Documents provide support, through a guarantee or otherwise, for any Swap
Agreement or any other agreement or instrument that is a QFC (such support, “QFC
Credit Support”, and each such QFC, a “Supported QFC”), the parties acknowledge
and agree as follows with respect to the resolution power of the Federal Deposit
Insurance Corporation under the Federal Deposit Insurance Act and Title II of
the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the
regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in
respect of such Supported QFC and QFC Credit Support (with the provisions below
applicable notwithstanding that the Loan Documents and any Supported QFC may in
fact be stated to be governed by the laws of the State of New York and/or the
United States or any other state of the United States):

In the event a Covered Entity that is party to a Supported QFC (each, a “Covered
Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime,
the transfer of such Supported QFC and the benefit of such QFC Credit Support
(and any interest and obligation in or under such Supported QFC and such QFC
Credit Support, and any rights in property securing such Supported QFC or such
QFC Credit Support) from such Covered Party will be effective to the same extent
that such transfer would be effective under the U.S. Special Resolution Regime
if the Supported QFC and such QFC Credit Support (and any such interest,
obligation and rights in property) were governed by the laws of the United
States or a state of the United States. In the event a Covered Party or a BHC
Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S.
Special Resolution Regime, Default Rights under the Loan Documents that might
otherwise apply to such Supported QFC or any QFC Credit Support that may be
exercised against such Covered Party are permitted to be exercised to no greater
extent than the extent to which such Default Rights could be exercised under the
U.S. Special Resolution Regime if such Supported QFC and the Loan Documents were
governed by the laws of the United States or a state of the United States.
Without limitation of the foregoing, it is understood and agreed that the rights
and remedies of the parties with respect to a Defaulting Lender shall in no
event affect the rights of any Covered Party with respect to a Supported QFC or
any QFC Credit Support.
SECTION 2.Borrowing Base. In reliance on the covenants and agreements contained
in this Fourth Amendment, and subject to the satisfaction of the conditions
precedent set forth in Section 3 hereof, Administrative Agent and the Required
Lenders agree that the Borrowing Base shall be and hereby is

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

reaffirmed at $325,000,000, effective as of the Fourth Amendment Effective Date
and continuing until the next Scheduled Redetermination, Interim Redetermination
or other redetermination or adjustment of the Borrowing Base thereafter. The
Borrower, the Administrative Agent, and the Lenders acknowledge that the
reaffirmation of the Borrowing Base provided for in this Section 2 constitutes
the Scheduled Redetermination intended to be effective on, or as promptly as
reasonably practicable after, November 1, 2019, as referenced in Section 2.07(b)
of the Credit Agreement, and that this Fourth Amendment constitutes the New
Borrowing Base Notice with respect to such Scheduled Redetermination.
