Gentlemen and Ladies:

We refer to the Amended and Restated Credit Agreement, dated as of July 24, 2013
(together with all amendments and other modifications, if any, from time to time
thereafter made thereto, the “Credit Agreement”), among Marina District Finance
Company, Inc., a New Jersey corporation (the “Borrower”), Marina District
Development Company, LLC, a New Jersey limited liability company (“MDDC”), the
various financial institutions (the “Lenders”) as are, or shall from time to
time become, parties thereto, and Wells Fargo Bank, National Association as
administrative agent (the “Administrative Agent”) for the Lenders and as L/C
Issuer and Swing Line Lender. Unless otherwise defined herein or the context
otherwise requires, terms used herein have the meanings provided in the Credit
Agreement.

1.Incremental Term Facility. Pursuant to Sections 2.17 and 2.18 of the Credit
Agreement, the Borrower has requested a term loan facility (the “Incremental
Term Facility”) in an aggregate principal amount of up to $650,000,000 and the
Lenders party hereto (the “Incremental Term Lenders”) are willing to provide
such Incremental Term Facility pursuant to the terms of this joinder agreement
and refinancing amendment (this “Agreement”). This Agreement will be an
“Incremental Term Facility Joinder” and a “Refinancing Amendment” as described
in Section 2(a) and (b) and the loans made hereunder (the “Incremental Term
Loans”) will be “Term Loans” for purposes of, and as defined in, the Credit
Agreement and will be subject to all terms and conditions of the Credit
Agreement. For the avoidance of doubt, the “Incremental Term Loans” include both
the Initial Incremental Term Loans (as defined below) and the Delayed Draw Term
Loans (as defined below).

2.Incremental Term Commitments.

(a)The Incremental Term Facility will be available in multiple borrowings as set
forth in this Section 2 but in, any event, in increments of no less than
$5,000,000. Each Incremental Term Lender hereby agrees, subject to satisfaction
of the conditions precedent set forth in Section 4.02 of the Credit Agreement
and in Section 3(a) and (b) below, to make initial Incremental Term Loans (the
“Initial Incremental Term Loans”) to the Borrower on a date which is on or after
the Incremental Term Facility Effective Date (as defined below) but before
August 31, 2015 (the “Initial Borrowing Date”) in the amount (such Lender’s
“Initial Incremental Term Commitment”) set forth opposite such

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

Incremental Term Lender’s name on Schedule I attached hereto, which Initial
Incremental Term Loans shall comprise an “Incremental Term Facility” under the
Credit Agreement. This Agreement shall become an effective “Incremental Term
Facility Joinder” under the Credit Agreement with respect to such Facility on
such date.

(b)Each Incremental Term Lender agrees, subject to satisfaction of the
conditions precedent set forth in Section 3(b) below, to make additional
Incremental Term Loans (the “Delayed Draw Term Loans”) to the Borrower from time
to time on any Business Day as the Borrower may request (each, a “Delayed Draw
Borrowing Date”) prior to the one-year anniversary of the Incremental Term
Facility Effective Date (the “Delayed Draw Commitment Termination Date”) in an
aggregate amount not to exceed the amount (such Lender’s “Delayed Draw
Commitment”) set forth opposite such Incremental Term Lender’s name on Schedule
I attached hereto. Each borrowing of Delayed Draw Term Loans on a Delayed Draw
Borrowing Date shall comprise an “Other Term Facility” under the Credit
Agreement and this Agreement shall become an effective “Refinancing Amendment”
under the Credit Agreement with respect to such Facility on such date.

(c)The Borrower and the Incremental Term Lenders hereby agree that the
Incremental Term Facility described in Section 1 above, including each
“Incremental Term Facility” and “Other Term Facility” (as such terms are defined
in the Credit Agreement) comprising the Incremental Term Facility (as described
in Section 1 above), shall upon the making of the relevant Incremental Term
Loans be treated as a single “Incremental Term Facility” or “Other Term
Facility” for purposes of the Credit Agreement and the other Loan Documents,
including for purposes of voluntary and mandatory prepayments (and determining
the Lenders’ Pro Rata Shares thereof) and for purposes of any voting matter
contemplated under the Credit Agreement or the other Loan Documents.

(d)Each Incremental Term Lender hereby acknowledges and confirms that it has
received a copy of the Credit Agreement (including the schedules and exhibits
thereto) and each other Loan Document. Each Incremental Term Lender acknowledges
that it has made its own independent investigation and credit evaluation of the
Borrower in connection with entering into this Agreement.

4.Interest and Fees.

(a)Subject to the provisions of Section 2.08(b) of the Credit Agreement, (i) at
any time and to the extent that the Incremental Term Loans are Eurodollar Rate
Loans, the Incremental Term Loans shall bear interest on the outstanding
principal amount thereof for each Interest Period at a rate per annum equal to
the Effective Eurodollar Rate (as defined below) for such Interest Period plus
the Term Loan Applicable Rate (as defined below) and (ii) at any time and to the
extent that the Incremental Term Loans are Base Rate Loans, the Incremental Term
Loans shall bear interest on the outstanding principal amount thereof at a rate
per annum equal to the Base Rate for such Interest Period plus the Term Loan
Applicable Rate; provided, that for purposes of calculating the Base Rate in
connection with the Incremental Term Loans, clause (b) of the definition of
“Base Rate” shall be deemed to refer to the Effective Eurodollar Rate.

“Effective Eurodollar Rate” means, for any Interest Period with respect to any
Incremental Term Loan, the greater of (x) the Eurodollar Rate in effect for such
Interest Period and (y) 1.00%.

“Term Loan Applicable Rate” means, with respect to the Incremental Term Loans,
(a) in the case of Eurodollar Loans, (i) at any time that the Total Leverage
Ratio is equal to or greater than 4.50 to 1.0, 6.00%,

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

(ii) at any time that the Total Leverage Ratio is equal to or greater than 3.50
to 1.0 but less than 4.50 to 1.0, 5.75%, (iii) at any time that the Total
Leverage Ratio is equal to or greater than 3.00 to 1.0 but less than 3.50 to
1.0, 5.50%, (iv) at any time that the Total Leverage Ratio is equal to or
greater than 2.50 to 1.0 but less than 3.00 to 1.0, 5.25%, and (v) at any time
that the Total Leverage Ratio is less than 2.50 to 1.0, 5.00%, and (b) in the
case of Base Rate Loans, (i) at any time that the Total Leverage Ratio is equal
to or greater than 4.50 to 1.0, 5.00%, (ii) at any time that the Total Leverage
Ratio is equal to or greater than 3.50 to 1.0 but less than 4.50 to 1.0, 4.75%,

1.0, 4.25%, and (v) at any time that the Total Leverage Ratio is less than 2.50
to 1.0, 4.00%.

Any increase or decrease in the Term Loan Applicable Rate resulting from a
change in the Total Leverage Ratio shall become effective as of the first
Business Day immediately following the date a Compliance Certificate is
delivered pursuant to Section 6.02(b) of the Credit Agreement in the case of the
first three fiscal quarters of any fiscal year and immediately following the
date a certification of the Total Leverage Ratio is delivered pursuant to
Section 6.02(c) of the Credit Agreement in the case of the final quarter of any
fiscal year; provided, however, that if a Compliance Certificate is not
delivered when due in accordance with Section 6.02(b) of the Credit Agreement or
a certification of Total Leverage Ratio is not delivered when due in accordance
with Section 6.02(c) of the Credit Agreement, then the Term Loan Applicable Rate
shall be the rate referred to in clause (a)(i) or (b)(i) of the definition
thereof (set forth above) as of the first Business Day after the date on which
such Compliance Certificate was required to have been delivered and shall
continue to apply until the first Business Day after the date such certificate
is delivered.

Notwithstanding the foregoing, in the event that the Effective Yield (as defined
below) for any Term Facility under the Credit Agreement (other than the
Incremental Term Facility contemplated in Section 1 hereof), as determined by
the Administrative Agent, is higher than the Effective Yield for the Incremental
Term Facility, as determined by the Administrative Agent, by more than 50 basis
points, then the interest rates referred to above shall be increased to the
extent necessary so that the Effective Yield for the Incremental Term Facility,
as determined by the Administrative Agent, is equal to the Effective Yield for
such other Term Facility minus 50 basis points. If necessary, this Agreement
shall be amended, in form and substance reasonably satisfactory to the
Administrative Agent and the Borrower, to reflect such increase in interest
rate.

(b)The Borrower shall pay to the Administrative Agent for the account of each
Incremental Term Lender in accordance with its Delayed Draw Commitment, an
unused fee (the “Delayed Draw Unused Fee”) equal to 0.25% per annum times the
actual daily amount of such Incremental Term Lender’s Delayed Draw Commitment.
The Delayed Draw Unused Fee shall accrue at all times from and after the
Incremental Term Facility Effective Date to and including the earliest to occur
of (i) the date on which the Delayed Draw Commitments are terminated in full
pursuant to Section 5(c) or reduced to zero as a result of the making of Delayed
Draw Term Loans and (ii) the Delayed Draw Commitment Termination Date, and shall
be due and payable quarterly in arrears on the last Business Day of each March,
June, September and December, commencing with the first such date to occur after
the Incremental Term Facility Effective Date, and on the Maturity Date as
described in Section 5(b) below, and calculated as provided in Section 2.10 of
the Credit Agreement.

5.Repayment of Incremental Term Loans; Termination or Reduction of Delayed Draw
Commitments.

(a)The Borrower shall make repayments of (i) the Initial Incremental Term Loans
on or before the last Business Day of each fiscal quarter of the Borrower
commencing with the fiscal quarter

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

of the Borrower ending December 31, 2015 in an amount equal to the Amortization
Percentage (as defined below) times the aggregate principal amount of the
Initial Incremental Term Loans made on the Initial Borrowing Date and (ii) the
Delayed Draw Term Loans on or before the last Business Day of each fiscal
quarter of the Borrower commencing with the first full fiscal quarter of the
Borrower ending after the Delayed Draw Borrowing Date for such Delayed Draw Term
Loans in an amount equal to the Amortization Percentage times the aggregate
principal amount of the Delayed Draw Term Loans made on such Delayed Draw
Borrowing Date.

“Amortization Percentage” means 0.25%.

(b)The Borrower shall repay the outstanding principal amount of all Incremental
Term Loans on July 16, 2023, which date shall be the Maturity Date for the

Delayed Draw Commitments, or from time to time permanently reduce the Delayed

standard, as applicable), five Business Days prior to the date of termination or
reduction and (ii) any such partial reduction shall be in an aggregate amount of
$5,000,000 or any whole multiple of $1,000,000 in excess thereof. The
Administrative Agent will promptly notify the Incremental Term Lenders of any
such notice of termination or reduction of the Delayed Draw Commitments. Any
reduction of the Delayed Draw Commitments shall be applied to the Delayed Draw
Commitments, as applicable, of each Incremental Term Lender according to its Pro
Rata Share of the aggregate Delayed Draw Commitments, as applicable. The Delayed
Draw Commitment of each Incremental Term Lender will be automatically reduced by
the principal amount of each Delayed Draw Term Loan made by such Incremental
Term Lender upon the making of such Delayed Draw Term Loan. All unpaid Delayed
Draw Unused Fees accrued until the effective date of any termination of the
Delayed Draw Commitments shall be paid on the effective date of such
termination.
