	SECTION 1.	PRELIMINARY STATEMENT 

 The Mohegan Tribal Gaming Authority (the
“Authority”), a governmental instrumentality of The Mohegan Tribe of Indians of Connecticut, a sovereign tribe recognized by the United States of America pursuant to 25 C.F.R. § 83 (the “Tribe”), has authorized
the issuance of its Floating Rate Senior Notes due December 15, 2017 (as may be amended, restated, supplemented or otherwise modified from time to time, the “Notes”), pursuant to a Note Purchase Agreement, of even date herewith
(as may be amended, restated, supplemented or otherwise modified from time to time, the “Note Purchase Agreement”), between the Authority, the Tribe (for purposes of the specific sections detailed therein), and the Purchasers party
thereto. 
 In order to induce the Purchasers to enter into the Note Purchase Agreement and to purchase the Notes from the Authority, the
Authority has agreed that it will cause each Guarantor to guarantee the Obligations of the Authority under the terms of the Notes and the Note Purchase Agreement pursuant to the terms and provisions hereof. 

Each Guarantor will receive direct and indirect economic, financial and other benefits from the indebtedness incurred under the Note Purchase
Agreement and the Notes by the Authority, and the incurrence of such indebtedness is in the best interests of each Guarantor. The Authority and each Guarantor have induced the Purchasers to purchase the Notes based on the consolidated financial
condition of each Guarantor and the Authority. 
 All acts and proceedings required by law and by the certificate of incorporation and
bylaws (or other applicable constitutive documents) of each Guarantor necessary to constitute this Guarantee a valid and binding agreement for the uses and purposes set forth herein in accordance with its terms have been done and taken, and the
execution and delivery hereof has been in all respects duly authorized.

failure has occurred in accordance with the terms and provisions of the Note Purchase Agreement and the Notes. In furtherance of the foregoing, if an Event of Default shall exist, the Guaranteed Obligations shall, in the manner and subject to the

 ANNEX 1 

GUARANTEE JOINDER 

GUARANTEE JOINDER, dated as of
[                    ], made by
                    , a                      (the
“Additional Guarantor”), in favor of each of the Noteholders. All capitalized terms not defined herein shall have the meaning ascribed to them in the Note Purchase Agreement or the Guarantee (as defined below), as applicable. 

 

	SECTION 1.	PRELIMINARY STATEMENT 

 The Mohegan Tribal Gaming Authority (the
“Authority”), a governmental instrumentality of The Mohegan Tribe of Indians of Connecticut, a sovereign tribe recognized by the United States of America pursuant to 25 C.F.R. § 83 (the “Tribe”), has heretofore
issued its Floating Rate Senior Notes due December 15, 2017 (as may be amended, restated, supplemented or otherwise modified from time to time, the “Notes”), pursuant to a Note Purchase Agreement, dated as of November 20,
2015 (as may be amended, restated, supplemented or otherwise modified from time to time, the “Note Purchase Agreement”), between the Authority, the Tribe (for purposes of the specific sections detailed therein), and the Purchasers
party thereto. 
 In connection with the Note Purchase Agreement, certain of the Authority’s Subsidiaries have entered into the
Guarantee Agreement, dated as of November 20, 2015 (as may be amended, restated, supplemented or otherwise modified from time to time, the “Guarantee”) in favor of each of the Noteholders. 

Pursuant to Section 10.12 of the Note Purchase Agreement, the Additional Guarantor is required to become a party to the Guarantee. 

The Additional Guarantor will receive direct and indirect economic, financial and other benefits from the indebtedness incurred under the Note
Purchase Agreement and the Notes by the Authority, and the incurrence of such indebtedness is in the best interests of the Additional Guarantor. 

All acts and proceedings required by law and by the certificate of incorporation and bylaws (or other applicable constitutive documents) of
the Additional Guarantor necessary to constitute this Guarantee Joinder a valid and binding agreement for the uses and purposes set forth herein in accordance with its terms have been done and taken, and the execution and delivery hereof has been in
all respects duly authorized. 
  

	SECTION 2.	GUARANTEE AND OTHER RIGHTS AND UNDERTAKINGS 

 Section 2.1 Guarantee and Other Rights and
Undertakings. By executing and delivering this Guarantee Joinder, the Additional Guarantor, as provided in Section 6.7 of the Guarantee, hereby becomes a party to the Guarantee as a Guarantor thereunder with the same force and effect as if
originally named therein as a Guarantor and, without limiting the generality of the foregoing, 







 
hereby agrees to all terms and provisions of the Guarantee applicable to it as a Guarantor thereunder and assumes all obligations and liabilities of a Guarantor thereunder. The Additional
Guarantor hereby represents and warrants that each of the representations and warranties contained in Section 5 of the Note Purchase Agreement, insofar as such representations pertain to it, is true and correct in all material respects on and
as of the date hereof (after giving effect to this Guarantee Joinder) as if made on and as of such date (except for representations and warranties expressly stated to relate to a specific earlier date, in which case such representations and
warranties shall be true and correct in all material respects as of such earlier date). Each reference to a “Guarantor” in the Guarantee shall be deemed to include the Additional Guarantor. The Guarantee is hereby incorporated herein by
reference. Except as expressly supplemented hereby, the Guarantee shall remain in full force and effect. 
 Section 2.2 Applicable Law. This
Guarantee Joinder shall be governed by and construed in accordance with the law of the State of New York, without regard to conflict of law principles that would result in the application of any Law other than the Laws of the State of New York. Each
party hereto each hereby consents to the application of New York civil law to the construction, interpretation and enforcement of this Agreement, and to the application of New York civil law to the procedural aspects of any suit, action or
proceeding relating thereto, including but not limited to legal process, execution of judgments and other legal remedies. 
 Section 2.3
Counterparts. This Guarantee Joinder may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto. 
 Section 2.4 Note Document. This Guarantee is a “Note
Document” as defined in the Note Purchase Agreement. 
 Section 2.5 Limited Waiver of Sovereign Immunity. The Additional Guarantor
does not consent to the enforcement, levy, or other execution of any judgment for money or other damages against any assets, real or personal, of the Tribe, except that the Additional Guarantor consents to the enforcement, levy and other execution
of any judgment for money or other damages, whether obtained as a result of a judicial, administrative, or arbitral proceeding, against any assets, real or personal (other than any property held in trust or subject to a restriction on alienation by
the United States and property of which the encumbrance or transfer is not permitted under any applicable federal or state law or regulation (the “Excluded Property”)) of the Additional Guarantor, but only to the extent set forth in the
remainder of this paragraph. Subject to the foregoing, the Additional Guarantor expressly and irrevocably waives its sovereign immunity, to the extent applicable (and any defenses based thereon) from unconsented suit, whether such suit be brought in
law or in equity, or in administrative proceedings or proceedings in arbitration, to permit the commencement, maintenance, and enforcement of any action, by a Purchaser (or any of its successors or permitted assigns), subject to any limitations
contained in this Guarantee Joinder, to interpret or enforce the terms of this Guarantee Joinder and to enforce and execute any judgment resulting therefrom against such Additional Guarantor or the assets of the Additional Guarantor (other than the
Excluded Property). Without limiting the generality of the foregoing, the Additional Guarantor waives its immunity (to the extent applicable) from unconsented suit to permit the maintenance of the following actions in respect of this Guarantee.

 (i) Courts. The Additional Guarantor waives its immunity from unconsented suit to permit
any court of competent jurisdiction to (A) enforce and interpret the terms of this Guarantee and award and enforce the award of damages against the Additional Guarantor owing as a consequence of a breach thereof, whether such award is the
product of litigation, administrative proceedings or arbitration; (B) determine whether any consent or approval of the Additional Guarantor has been improperly granted or unreasonably withheld; (C) enforce any judgment prohibiting the
Additional Guarantor from taking any action, or mandating or obligating the Additional Guarantor to take any action, including a judgment compelling the Additional Guarantor to submit to binding arbitration; and (D) adjudicate any claim under
the Indian Civil Rights Act of 1968, 25 U.S.C. § 1302 (or any successor statute). 
 (ii) Arbitration. The Additional Guarantor
waives its immunity from unconsented suit to permit arbitrators, appointed and acting under the commercial arbitration rules of the American Arbitration Association, to (1) enforce and interpret the terms of this Guarantee Joinder and to award
and enforce the award of any damages against the Additional Guarantor owing as a consequence thereof; (2) determine whether any consent or approval of a Guarantor has been improperly granted or unreasonably withheld; and (3) enforce any
judgment prohibiting the Additional Guarantor from taking any action, or mandating or obligating the Additional Guarantor to take any action, including a judgment compelling the Additional Guarantor to submit to binding arbitration.
