WHEREAS, Rubenstein resigned from his employment with the MTGA on February 16, 2018 (“Separation Date”); and

NOW THEREFORE, to resolve fully and finally all disputes and claims arising out of and/or relating to Rubenstein’s employment relationship with the MTGA, and with any other person or entity affiliated with or acting on behalf of the MTGA, to the date of this Agreement, and in consideration of, among other things, the mutual promises set forth herein, the receipt and adequacy of which consideration are acknowledged by Rubenstein and MTGA, Rubenstein and the MTGA hereby agree and stipulate as follows:

Rubenstein hereby acknowledges, represents and certifies that as of the effective date of this Agreement, he has not filed, will not file, and waives any claims, suits, or causes of action of any kind against the MTGA or any of the Released Parties (as defined and more fully set

1

forth in Section 4 of this Agreement) that Rubenstein could bring in any forum whatsoever arising out of or related to his employment or the separation of that employment with the MTGA up to the date of this Agreement, and he agrees that he will never file or assert such claims in any forum whatsoever. Rubenstein acknowledges and agrees that, if any claim, suit or cause of action is brought by any person, government agency, or any other entity in his behalf related to his employment or the separation of that employment with the MTGA, he shall only participate in any such claim, suit or cause of action to the extent required by applicable law and in no event shall he receive or recover any tangible benefit, other than the consideration to be paid pursuant to this Agreement.

The MTGA and Rubenstein agree that Rubenstein resigned from his employment with the MTGA on February 16, 2018. The parties further acknowledge and agree that all obligations of the MTGA to Rubenstein, except as specifically set forth herein, are terminated.

4

In consideration for the undertakings herein of Rubenstein, MTGA, on behalf of itself and its former, present and future affiliates, tribal members, council members, board members, directors, officers, principals, agents, employees and their respective successors and assigns, hereby waives and forever releases and discharges Rubenstein and his heirs, successors and assigns from and against any and all claims and causes of action of any kind whatsoever that any of them may have, now have or have had or may have had against Rubenstein, whether known or unknown, which arose or could have arisen out of Rubenstein’s employment with MTGA up to the execution of this Agreement.

Rubenstein recognizes that the MTGA, by entering into this Agreement, is not admitting any violation of any law, regulation, duty or obligation to Rubenstein or any wrongdoing or impropriety whatsoever; and Rubenstein similarly is not admitting any violation of law, regulation, duty or obligation to MTGA or any or impropriety whatsoever.

Rubenstein acknowledges that while employed by the MTGA, he had access to, possessed or was otherwise exposed to confidential information in connection with his employment concerning the MTGA, and that he was at all times under a duty to maintain the confidentiality of such information and not to use the same for his benefit or the benefit of another party. Rubenstein understands, acknowledges, and agrees that his duties, obligations and covenant to maintain the confidentiality of information concerning the MTGA continue indefinitely and do not terminate with the termination of his employment with the MTGA. By entering into this Agreement, Rubenstein agrees that any and all of his prior agreements to maintain the confidentiality of the MTGA information, including but not limited to those set forth in the Employment Agreement, shall continue hereinafter in full force and effect. Rubenstein hereby further affirms that he has returned to MTGA all documents, records, notebooks and similar repositories of or containing confidential information (“Confidential Documents”) and all personal property of the MTGA that were in his possession, including but not limited to keys, access cards, key fobs, cell phones, computers, documents in any form, customer and patron lists or other information about MTGA and its affiliates and its and their patrons including financial information, legal documents and information, and marketing and financial plans and strategies; and that any Confidential Documents not returned to MTGA have been destroyed or permanently and irrevocably deleted. In the event that Rubenstein should at any time in the future identify any confidential information or personal property of the MTGA in his actual or constructive possession, he shall forthwith return the same to the MTGA.

5

Rubenstein also acknowledges that he is and remains bound by and subject to a covenant not to compete with the MTGA in New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, Rhode Island, Vermont, New Hampshire and Maine (the “Restricted Area”) for a period of one year after the Separation Date (the “Restricted Period”). Rubenstein covenants that in the Restricted Area and for the duration of the Restricted Period he shall abide by the terms of Section 8 of the Employment Agreement.

At all times material herein, Rubenstein has served in a professional capacity as General Counsel to MTGA. The MTGA expressly reserves and does not waive the attorney-client privilege between MTGA and Rubenstein. Rubenstein shall notify MTGA of any written or oral request or demand, or any compulsory process, issued to or served upon him, for testimony, production of records, or assistance, by or on behalf of any person or entity in any proceeding before any court, arbitral forum, or administrative agency, or in any inquiry or investigation prior or preparatory to any proceeding, in which MTGA is a party or in which MTGA has an interest; such notice by Rubenstein to be provided in writing at the earliest opportunity to the President and Chief Executive Officer of MTGA.

MTGA and Rubenstein mutually covenant and agree that executive employees with the title of Senior Vice President or higher of MTGA and all Management Board members will make no comments, remarks or statements disparaging Rubenstein and Rubenstein will not make any comments, remarks or statements disparaging the MTGA or any of the Released Parties. Notwithstanding the foregoing, in no event shall Rubenstein be deemed to be in violation of his obligations under this covenant for providing information to and/or full and truthful responses to oral or written inquiries from any Tribal, State or Federal governmental or quasi-governmental agency(ies), including without limitation any gaming regulatory agencies, provided that such responses do not violate the attorney-client privilege, or are otherwise required by applicable law. Similarly, neither the MTGA nor the Released Parties shall be deemed in violation of its or their obligations under this covenant for providing information to and/or full and truthful responses to oral or written inquiries from any Tribal, State or Federal governmental or quasi-governmental agency(ies), including without limitation any gaming regulatory agencies, or as otherwise required by applicable law.

Rubenstein also agrees that he shall cooperate with and assist MTGA in addressing matters that arose during the course of his employment, including without limitation (i) the defense of any claims that may be made against MTGA, (ii) the prosecution of any claims that may be made by MTGA, to the extent that any such claims may relate to the duties and services performed by Rubenstein, and (iii) MTGA’s response to any inquiries by any gaming regulatory authorities having oversight of the MTGA or its subsidiaries Rubenstein further agrees to cooperate with and assist MTGA to a reasonable extent in the transition of business matters from Rubenstein to other executives at the MTGA through May 18, 2018. MTGA agrees to reimburse

6

Rubenstein for all of his reasonable out-of-pocket costs and expenses, including payment of reasonable attorneys’ fees necessarily incurred by Rubenstein in retaining counsel of his choice, in connection with providing such assistance and cooperation, and reimbursement of travel expenses in accordance with MTGA’s travel and reimbursement policy, unless any such reimbursement is expressly prohibited by written order issued by any gaming regulatory authority. MTGA acknowledges that Rubenstein’s cooperation and assistance contemplated hereby shall be subject to his reasonable availability.

MTGA shall take such reasonable steps as may be required to ensure the orderly withdrawal of Rubenstein’s gaming license(s) and/or gaming application(s) in each jurisdiction in which the termination of Rubenstein’s employment with the MTGA requires action by the MTGA or its subsidiaries to effect such withdrawal.

MTGA agrees to provide reasonable cooperation and assistance to Rubenstein in connection with any regulatory inquiries arising out of his employment, to the extent that such cooperation and assistance is not in conflict with any applicable code of conduct or regulatory requirement.

Rubenstein hereby acknowledges and agrees that he has been represented by legal counsel of his choosing in the development of this Agreement, that he has been advised of and is aware of the rights that he is waiving under this Agreement, and that he enters into this Agreement knowingly and voluntarily.

If any provision of this Agreement is determined to be null, void, or inoperable for any reason, such provision shall be severable and the remaining provisions of this Agreement shall remain in full force and effect; provided that, in the event that the restrictions on Rubenstein’s competition as set forth in Section 8 of the Employment Agreement and Section 8 of this Agreement are found unenforceable as a result of any claim, suit or cause of action brought by Rubenstein or by any person, government agency, or any other entity on Rubenstein’s behalf at Rubenstein’s direction and as a result thereof Rubenstein becomes engaged in such employment or other activity that would have been prohibited by such covenant not to compete, the MTGA’s obligations to make the payments described in Section 3 of this Agreement shall cease.

The parties agree that the provisions of Sections 17 and 18 of the Employment Agreement concerning Dispute Resolution are incorporated herein by reference. Notwithstanding the foregoing, in the event that Rubenstein breaches any of the provisions of Paragraph 8 of this Agreement, Rubenstein understands that the MTGA may exercise any available remedies including its right to bring an action to enjoin any such breach in any court having personal jurisdiction over him, as he acknowledges that MTGA would suffer irreparable harm in the event

7

of such breach. Rubenstein further acknowledges that in no event shall MTGA have to prove special damages before proceeding with an injunction against him. Rubenstein also agrees that in the event he breaches any duty of confidentiality to MTGA and/or any covenant not to compete with MTGA, the MTGA may recover, in addition to any other legal damages, its reasonable attorneys’ fees, court costs and other litigation expenses incurred in investigating and prosecuting any breach, provided that Rubenstein may recover from the MTGA his reasonable attorneys’ fees, costs, and other litigation expenses if he prevails in any such proceeding. In addition, with respect to his breach or threatened breach of the confidentiality and/or non-competition provisions herein, MTGA has the right to notify Rubenstein’s new or prospective employer of the terms and conditions of this Agreement.

This Agreement shall be construed in accordance with the laws of the State of Connecticut. Rubenstein understands and agrees that he may not assign this Agreement or any of his rights under this Agreement.

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which shall together constitute one and the same instrument.

IN WITNESS WHEREOF, the parties hereto set forth their hands on the dates opposite their signatures.
