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.

Section 2.1 Guaranteed Obligations. Each Guarantor, in consideration of the execution and delivery of the Note Purchase Agreement, the purchase of the Notes by the Purchasers and other consideration, hereby irrevocably, unconditionally, absolutely, jointly and severally

guarantees, on a continuing basis, to each holder of Notes (each such holder being referred to herein as a “Noteholder” and, collectively, as the “Noteholders”), as a primary obligor and not merely as a surety, until final and indefeasible payment has been made in cash:

(a) the due and punctual payment of Obligations, including, without limitation, overdue interest, indemnification payments and all reasonable, out-of-pocket costs and expenses incurred by the Noteholders in connection with enforcing any obligations of the Authority under the Note Purchase Agreement and the Notes; it being the intent of each Guarantor that the guaranty set forth herein shall be a continuing guaranty of payment and not a guaranty of collection; and

(b) the prompt and complete payment, on demand, of any and all reasonable, out-of-pocket costs and expenses incurred by the Noteholders in connection with enforcing the obligations of such Guarantor hereunder, including, without limitation, the reasonable fees and disbursements of the Noteholders’ counsel.

All of the obligations set forth in clauses (a) and (b) of this Section 2.1 are referred to herein as the “Guaranteed Obligations” and the guaranty thereof contained herein is referred to herein as the “Unconditional Guarantee.” The Unconditional Guarantee is an absolute, unconditional, continuing and irrevocable guaranty of payment and performance and shall remain in full force and effect until the full, final and indefeasible payment in cash of the Guaranteed Obligations.

Section 2.2 Performance under the Note Purchase Agreement. In the event the Authority fails to pay, perform. keep, observe, or fulfill any Guaranteed Obligation specified in clause (a) of Section 2.1 in the manner provided in the Notes or in the Note Purchase Agreement, each Guarantor shall cause forthwith to be paid the moneys in respect of which such 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 limitations provided in the Note Purchase Agreement for the acceleration of the Notes, forthwith become due and payable without notice, regardless of whether the acceleration of the Notes shall be stayed, enjoined, delayed or otherwise prevented.
