     THE MTGA AND I THEREFORE, in consideration of my employment by the MTGA
after the date of this Agreement and the additional consideration set forth in

                                   Page 3 of 8

     (b) I also covenant and agree that in the event that I voluntarily
terminate my employment by resignation, I shall deliver written notice of my
intention to terminate my employment sixty (60) days in advance of my
termination date to the President/CEO. I understand and acknowledge that if I

in full force and effect for the duration and within the Non-Compete Area as set
forth herein.

     (c) I acknowledge that my skills are transferable or applicable to
industries and entities which are not in competition with the MTGA and/or that I
may engage in the gaming industry outside the Non-Compete area, so that my
covenants against competition with the MTGA will not prevent me from providing
for myself and my family. I understand that I may make written request to the
President/CEO of the MTGA for a waiver of any of the provisions of this
Paragraph, and that the decision of the President/CEO in response to any such
request for waiver shall be final and shall not be subject to an appeal or
review in any forum.

     In consideration for my obligations and undertakings herein, expressly
including my covenant not to compete with the MTGA:

the President/CEO, increase my Base Salary by 9.38 percent to $175,000.00;

resignation and give the written notice required by Paragraph 2(b), the MTGA
shall continue to pay my Base Salary from the date of my notice of resignation
through and including the sixtieth (60th) calendar day following my delivery of
my resignation notice, so long as I remain fully in compliance with all of my
other covenants under this Agreement.

     (c) If the MTGA exercises its right to terminate my employment at its
discretion pursuant to Paragraph 4(a) and without "cause" as set forth in
Paragraph 4(b), then the MTGA shall pay me:

as was in effect at the date of my termination for a period of one calendar year
from the date of my termination, and

         (ii) a lump sum in the amount of twenty five thousand dollars
($25,000.00) for relocation expenses subject to all deductions required by
applicable law.

                                   Page 4 of 8

     I hereby acknowledge that the foregoing represents good and sufficient
consideration to which I am not otherwise entitled so as to assure that this
agreement may be enforced against me in the event of my breach.

     4. TERMINATION

     (a) Termination At Will

     I understand, acknowledge and agree that my employment is "at will," in
that either I or the MTGA, independently, can terminate my employment for any
reason or for no reason, at any time, with or without notice, subject only to
the terms and limitations of this Agreement. If I terminate my employment by
voluntary resignation and provide written notice pursuant to Paragraph 2(b), I
may, unless I am otherwise disqualified by my breach of other terms of this
Agreement, receive the benefits set forth in Paragraph 3(b). If the MTGA
terminates my employment at its discretion and without "cause" as described more
fully below, the MTGA shall pay me the benefits set forth in Paragraph 3(c).

     (b) Termination for Cause

     I acknowledge and agree that the MTGA may terminate this Agreement for
cause, and that in the event of a termination for cause, the MTGA shall have no
obligation to pay me any of the benefits described in Paragraph 3(c) or any
other benefit except that required by applicable law.

     I understand that cause for termination includes, but is not limited to:

     o   My conviction of a criminal offense;
     o   My violation of Mohegan Sun policies, including, but not limited to, my
         violation of the standards for personal conduct set forth in Mohegan
         Sun Policy #27 (as amended);
     o   My breach of my covenants under this Agreement, including my covenants
         not to compete;
     o   My aiding, assisting, or abetting any other person to breach a covenant
         not to compete;
     o   Suspension or revocation of my gaming license;
     o   My engagement, directly or indirectly, in a conflict of interest;
     o   My failure or refusal to perform my Executive Assignment; or
     o   Other serious misconduct by me.

                                   Page 5 of 8

     I understand that the foregoing is illustrative of grounds for my
termination for cause, and is not an exclusive or exhaustive list.

     I understand that I have a right to a rudimentary hearing prior to the
termination of my employment for cause, at which hearing I shall be afforded an
opportunity to present reasons to the President/CEO or his designee why the
termination should not be imposed. However, I understand that any such hearing
shall be subject to such limitations in time and scope that the MTGA may impose,
and that I may obtain a review of the termination decision pursuant to the
"Remedies" set forth in this Agreement.

     (c) Confidentiality of MTGA Records

     I agree that all records, material and information obtained by me in the
course of my employment with the MTGA shall at all times be treated and
maintained in confidence and shall remain the exclusive property of the MTGA
during and following my employment with the MTGA. I agree that I shall at all
times adhere to all policies, standards and procedures as established by the
MTGA for protecting the confidentiality of information and records, including
but not limited to trade secrets.

     (d) Return of MTGA Documents Upon Termination

     Upon termination of my employment with the MTGA, I will return to and leave
with the MTGA all documents, records and notebooks concerning the business of
the MTGA, including copies thereof, then in my actual or constructive
possession, whether prepared by me or by others, and I will not duplicate such
materials for my own use or the use of another person, corporation or entity at
any time, either during or following my employment.

     5. REMEDIES.

     (a) I recognize that if I violate the covenants and undertakings of this
Agreement I may cause the MTGA irreparable injury and damage. Therefore, the
MTGA and I agree that, if I violate this Agreement, the MTGA may seek to enjoin
my actions which are in breach of this Agreement and that the MTGA is entitled
to recover from me all of its reasonable costs and expenses, including
reasonable attorney's fees, incurred by or on behalf of the MTGA in the
enforcement of this Agreement or any part thereof and in its investigation of my
violation of this Agreement, as well as any damages that may be proven to the
satisfaction of a court of competent jurisdiction.

     (b) I understand that the MTGA may disclose this Agreement to any entity
with whom I may become affiliated or employed following the termination of my
employment with and by the MTGA.

     (c) I understand that the Mohegan Tribe of Indians of Connecticut and the
MTGA have established the Mohegan Gaming Disputes Court on the Mohegan
Reservation. I consent to the exercise of personal jurisdiction over me by the
Mohegan Gaming Disputes Court.

     (d) I understand and agree that, since I am not restricted from travelling
and relocating, the MTGA may at its discretion bring an action to enforce this
Agreement against me in any court that can assert personal jurisdiction over me,
including but not limited to the Gaming Disputes Court.

     (e) I understand and agree that any claim by me that the MTGA has breached
its obligations to me under this Agreement may be asserted solely and
exclusively in the Gaming Disputes Court. In order to permit the Gaming Disputes
Court to assert subject matter jurisdiction over such a claim, the MTGA hereby
grants a limited waiver of its sovereign immunity and consents to suit by me for
enforcement of the MTGA's obligations under this Agreement but limits said
waiver so that the maximum amount I may recover is the amount authorized to be
paid to me by Paragraph 3(c), and the MTGA shall not be liable to me for any
additional or consequential damages.

     6. EFFECT OF WAIVERS.

     The failure of the MTGA to insist upon strict adherence to one or more or
all of the covenants and restrictions set forth above, on one or more occasions,
or the failure to insist upon strict adherenece by another MTGA employee who is
a party to an agreement similar to this Agreement, shall not be construed as a
waive of the MTGA's right thereafter to require strict compliance with any or
all of such covenants or restrictions.

     7. PARTIAL INVALIDITY.

     I agree that, if any part of this Agreement is held to be invalid or
unenforceable for any reason, the remaining covenants and restrictions shall
remain in full force and effect; and if invalidity or unenforceability is due to
the unreasonableness of the time or geographical areas covered by Paragraph 2,
such provisions shall be effective for whatever length of time and within such
area as a court of competent jurisdiction deems appropriate.

     8. APPLICABLE LAW.

     This Agreement shall be governed for all purposes by the Constitution and
laws of the Mohegan Tribe of Indians of Connecticut.

     9. ACKNOWLEDGEMENT.

     (a) I have had an opportunity to review fully a copy of this Agreement
prior to signing it and I have carefully read and I understand all of the terms
stated in this Agreement.

     (b) I understand that I must sign and abide by this Agreement in order to
be eligible to receive the consideration described in Paragraph 3 of this
Agreement.

     10. AMENDMENTS

     This Agreement may be amended. However, to become binding on the MTGA, any
amendment or modification must be set forth in a written document signed by the
President/CEO. In the event that I request a substantial modification of my work
assignment, working hours, title, or other material change in the terms and
conditions of my employment, such request shall be directed to the
President/CEO, who shall decide whether to grant or deny the request in whole or
in part and whether to modify this Agreement or the terms and conditions of my
employment. The decision of the President/CEO shall be final. My covenants not
to compete will remain in full force and effect regardless of any modification
of the terms and conditions of this Agreement.

     11. SUPERSEDENCE

     This Agreement supersedes any and all prior agreements between me and the
MTGA concerning or relating to my employment. This Agreement shall be construed
in harmony with all employment-related policies, standards, and procedures
adopted by the MTGA and/or the President/CEO, but in the event of any conflict
between the terms of this Agreement and any policy, standard or procedure
adopted by the MTGA for general application to MTGA employees, the terms of this
Agreement shall be given controlling effect. By way of example, but without
limitation, the remedies set forth in Paragraph 5 herein shall supersede the
procedures set forth in Mohegan Sun Policy #27 to the extent that said Policy
#27 conflicts with this Agreement.
