1.1      Additional Leased Property . Landlord and Tenant hereby agree that from and after the Effective Date, (i) the Empire City Casino and Yonkers Raceway, Yonkers, New York (“ Empire ”) shall be added to the “List of Facilities” set forth on Exhibit A to the Master Lease, (ii) the legal description of Empire attached hereto as Schedule 1 (Part I) shall be added to Part I of Exhibit B to the Master Lease, and the leases and/or subleases attached hereto as Schedule 1 (Part II) shall be added to Part II of Exhibit B to the Master Lease, (iii) Empire shall constitute a portion of the Leased Property, and shall be a Facility, for all purposes under the Master Lease, (iv) Empire shall be subject to all of the terms and conditions of the Master Lease, as modified by this Amendment and as the same may be further modified from time to time, and (v) Empire shall be subleased by Tenant to one or more Operating Subtenants pursuant to one or more Operating Subleases in accordance with the Master Lease.

1.2     Base Rent . From and after the Effective Date, the amount of Six Hundred Ninety Five Million Eight Hundred Forty Four Thousand Dollars ($695,844,000) set forth in the definition of “Base Rent” is hereby replaced with the amount of Seven Hundred Forty Million Eight Hundred Forty Four Thousand Dollars ($740,844,000), and the Base Rent initially allocated to Empire shall be Forty Five Million Dollars ($45,000,000) (the “ Base Rent

Adjustment Amount ”). The Base Rent Adjustment Amount payable during any Lease Year or portion thereof consisting of more or less than twelve (12) calendar months shall be prorated on a monthly basis such that the Base Rent Adjustment Amount that is included within the Base Rent for each calendar month is equal to the Base Rent Adjustment Amount divided by twelve (12). In the event the month in which the Base Rent Adjustment Amount takes effect is a partial month, Tenant shall pay (i) Base Rent (calculated without application of the Base Rent Adjustment Amount) for such month in accordance with Section 3.1 of the Master Lease and (ii) a portion of the Base Rent Adjustment Amount which shall be prorated on a daily basis such that the Base Rent Adjustment Amount for such calendar month is equal to the monthly Base Rent Adjustment Amount divided by the actual number of days in such month and multiplied by the number of days for which the adjustment is applicable.

1.3      Percentage Rent . From and after the Effective Date, the amount of Seventy Four Million Five Hundred Thousand Dollars ($74,500,000) forth in the definition of “Percentage Rent” is hereby replaced with the amount of Seventy Nine Million Five Hundred Thousand Dollars ($79,500,000), and the Percentage Rent initially allocated to Empire shall be Five Million Dollars ($5,000,000) (the “ Percentage Rent Adjustment Amount ”). The Percentage Rent Adjustment Amount payable during any Lease Year or portion thereof consisting of more or less than twelve (12) calendar months shall be prorated on a monthly basis such that the Percentage Rent Adjustment Amount that is included within the Percentage Rent for each calendar month is equal to the Percentage Rent Adjustment Amount divided by twelve (12). In the event the month in which the Percentage Rent Adjustment Amount takes effect is a partial month, Tenant shall pay (i) Percentage Rent (calculated without application of the Percentage Rent Adjustment Amount) for such month in accordance with Section 3.1 of the Master Lease and (ii) a portion of the Percentage Rent Adjustment Amount which shall be prorated on a daily basis such that the Percentage Rent Adjustment Amount for such calendar month is equal to the monthly Percentage Rent Adjustment Amount divided by the actual number of days in such month and multiplied by the number of days for which the adjustment is applicable. For the purpose of calculating Percentage Rent at the next Percentage Rent Reset Date, the “average annual Net Revenues” of any Facility added to the Leased Property during the trailing five calendar year period prior to such Percentage Rent Reset Date shall be calculated taking into consideration only the portion of such trailing five-year period during which the Facility was included as Leased Property under the Master Lease commencing on the date such Facility was added to the Leased Property.

1.4      Identified Subleases . In addition to the Identified Subleases indicated by letters from Landlord to Tenant dated April 25, 2016, August 2, 2016, and October 5, 2017, the definition of Identified Subleases shall also include those certain leases and/or subleases identified in a supplemental letter of even date herewith from Tenant to Landlord.

1.5      Gaming Licenses . The description of gaming licenses contained on Schedule 2 attached hereto shall be added to Exhibit D to the Master Lease.

1.6      Landlord ROFO . Tenant agrees that during the Term, neither Tenant nor any of its Affiliates shall sell or otherwise transfer, directly or indirectly, any portion of the Development Tracts on which Tenant shall have constructed gaming facilities (the “ Empire ROFO Property ”), unless Tenant shall first offer Landlord the opportunity to purchase such

2

Empire ROFO Property, on the same terms and conditions, mutatis mutandis , which are set forth in Section 7.4 of the Master Lease, except that if Landlord exercises such opportunity to purchase, then such Empire ROFO Property shall become part of the Empire Facility under the Master Lease instead of a new Facility, and the Master Lease shall be amended, including amending the Base Rent, to adjust the terms that apply to the Empire Facility to incorporate the Empire ROFO Property therein.

ARTICLE II

Reaffirmation of Guaranty

2.1      Reaffirmation of Guaranty . By executing this Amendment, Guarantor acknowledges and agrees that Tenant’s obligations under the Master Lease have been modified by this Amendment and therefore Guarantor’s Obligations (as defined in the Guaranty) have been modified by this Amendment. Guarantor hereby reaffirms the Guaranty and Guarantor’s Obligations thereunder, as modified by this Amendment.

ARTICLE III

New York Regulatory Requirements

3.1      Approval by the New York State Gaming Commission . This Amendment is subject to the receipt of any necessary approvals from the New York State Gaming Commission.

ARTICLE IV
