HOLDING CO., LLC (the “Company”). BOYD ATLANTIC CITY, INC., a New Jersey corporation (“Boyd Sub”). BOYD GAMING CORPORATION, a Nevada corporation (“Boyd”). MAC, CORP., a New Jersey corporation
(“MR Sub”), and MGM MIRAGE, a Delaware corporation. 
 Reference is made to (a) the Operating Agreement of
the Company (the “Operating Agreement”), adopted pursuant to the Contribution and Adoption Agreement, dated as of December 13, 2000, among the Company, Boyd Sub and MR Sub (the Operating Agreement, taken together with the
amendments thereto pursuant to this Agreement, is sometimes referred to in this Agreement as the “Amended Operating Agreement”), and (b) the proposed Stipulation of Settlement (as hereinafter defined). Capitalized terms used
and not otherwise defined herein shall have the meanings respectively ascribed thereto in the Operating Agreement. 
 In
consideration of the premises and the covenants and agreements set forth herein, and for other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 

1. Boyd Sub hereby (a) approves the Transfer by MR Sub of its entire Interest (the “Subject
Interest”) to the Trust (as hereinafter defined) and (b) agrees that the requirements of Section 11.4 of the Operating Agreement shall not apply to such Transfer. Upon such Transfer, the Trust shall, without necessity of any
approval, consent or acknowledgment by Boyd Sub, (i) be admitted as a Member of the Company in the place of MR Sub, (ii) succeed to the Capital Account of MR Sub and (iii) have all rights of a Member under the Amended Operating
Agreement and all rights under the Amended Operating Agreement incident to the ownership of the Subject Interest, and the Trustee (as hereinafter defined) shall have the power to exercise all such rights. Boyd Sub will remain the Managing Member
following the Transfer of the Subject Interest to the Trust, subject to the provisions of the Amended Operating Agreement (including Section 9.3 thereof). 

2. Boyd Sub acknowledges that the purpose of the Trust is to provide for the sale of the Subject Interest (and certain
related assets contemplated by the Stipulation of Settlement) and the remittance of the proceeds therefrom to MGM MIRAGE (the economic beneficiary of the Trust) or its designated subsidiary or Affiliate. The Company and Boyd Sub agree to cooperate,
as may reasonably be requested by MGM MIRAGE or the Trustee, in connection with efforts to market and (subject to the right of first refusal with respect to Interests under Section 11.4 of the Amended Operating Agreement), sell the Subject
Interest and such related assets. Notwithstanding anything to the contrary in the Amended Operating Agreement or otherwise, Boyd Sub: 

(a) agrees that the Company shall, and Boyd Sub shall and shall cause the Company and its subsidiaries to,
(i) afford to MGM MIRAGE and the Trustee (as applicable), their respective representatives and advisors, and entities and persons to whom the Subject Interest is marketed on behalf of MGM MIRAGE or the Trustee (“Bidders”), and
the respective representatives, advisors and financing sources of Bidders (“Bidder Team Members”), such access to the Company’s and its subsidiaries’ properties, contracts, commitments, ledgers, books and records (subject
to Section 3(b) of this Agreement), and to appropriate officers, employees, 







 
representatives and accountants of the Company and its subsidiaries as reasonably designated by the Company, in each case, as may reasonably be requested by MGM MIRAGE or the Trustee to
facilitate the investigation, marketing, valuation and sale (and financing for a buyer’s acquisition) of the Subject Interest, (ii) direct appropriate members of senior management of the Company and its subsidiaries, as reasonably
designated by the Company, and representatives of the Company’s independent auditors, to participate in a reasonable number of meetings and due diligence sessions with Bidders, Bidder Team Members, MGM MIRAGE, the Trustee, and their respective
and representatives and advisors, in connection with such investigation, marketing, valuation, sale and financing, and (iii) cooperate with and, as may reasonably be requested by MGM MIRAGE or the Trustee, assist MGM MIRAGE and the Trustee, in
providing information to be utilized in the preparation of marketing materials with respect to the Subject Interest, and disclosure schedules and similar documents in connection with any agreement to sell the Subject Interest; 

(b) (i) hereby approves and consents to the Transfer by the Trust of the Subject Interest to a Third Party, subject only
to the requirements of Section 11.4 of the Amended Operating Agreement, and (ii) agrees that upon a sale of the Subject Interest by the Trust, the transferee of the Subject Interest shall (subject to the requirements under the New Jersey
Casino Control Act, but without necessity of any approval, consent or acknowledgment by Boyd Sub) be admitted as a Member of the Company in the place of the Trust and have all rights of a Member under the Amended Operating Agreement and all rights
under the Amended Operating Agreement incident to the ownership of the Subject Interest and, without limiting the generality of the foregoing, the Trust, MGM MIRAGE and MR Sub shall be entitled to assign their respective rights under the Amended
Operating Agreement and in and to related assets, in whole or in part in their discretion, to such transferee; and 

(c) agrees that, if requested to do so by the Trust or the transferee of the Subject Interest, the Managing Member, on
behalf of the Company, shall elect to adjust the basis of the assets of the Company for federal income tax purposes in accordance with Section 754 of the Code for the Company’s taxable year in which the sale of the Subject Interest by the
Trust occurs. For the avoidance of doubt, Section 7.8(a) of the Operating Agreement remains in effect and is not limited by this Agreement. 

3. (a) In connection with any disclosure by MGM MIRAGE or the Trustee to a Bidder of Company confidential
information, MGM MIRAGE or the Trustee, as the case may be, shall require such Bidder to agree in writing to maintain the confidentiality of such information on terms customary for a sale transaction comparable to the sale transaction contemplated
herein and in the Stipulation of Settlement, and the Company shall be a third-party beneficiary of each such confidentiality agreement. MGM MIRAGE or the Trustee shall make good faith efforts to negotiate such confidentiality agreement and the
initial draft of such confidentiality agreement provided to each Bidder shall be based on the form of confidentiality agreement agreed to as of the date hereof by the parties hereto and attached as Exhibit A. Following execution of each such
confidentiality agreement, Boyd Sub shall be provided a copy thereof. 
 (b) Boyd Sub shall not be required to
provide to Bidders (i) the confidential patron database of the Company, or any summary thereof or detailed information related thereto 

 

 2 








 
(provided that Boyd Sub shall in any event make available the total number of patrons in the patron database of the Company, the geographic breakdown (reflected on a percentage basis) of patrons
identified in such database and semi-annual reports on the number of patrons added to the patron database); (ii) any individual or departmental salaries and wages, other than as may be included in any union collective bargaining agreement;
(iii) confidential prospective marketing strategies and plans, or the effectiveness or results of the implementation thereof; (iv) confidential settlement agreements (provided that Boyd Sub shall in any event make available information
relating to liabilities relating to such settlement agreements and a fair description of the claims, their background and status (however the names (but not a fair description) of the individual parties may be redacted)); (v) confidential
security or surveillance reports of the Company’s hotel and casino facility, except for information that would reasonably be expected to be material to an evaluation of the Subject Interest; and (vi) vendor price lists and purchase
contracts (provided that Boyd Sub shall in any event make available (A) a summary of material terms of purchase contracts that are relevant to the evaluation of the Subject Interest by the Bidder, (B) purchase contracts providing for
payments by or to the Company or any of its subsidiaries in excess of $ 1 million in any fiscal year and $3 million in the aggregate during the term thereof, or that include non-competition, non-solicitation or exclusivity covenants and
(C) other contracts that are material to the Company or its subsidiaries, their business and operations). Notwithstanding anything to the contrary in the foregoing, in connection with late stage negotiations between MGM MIRAGE or the Trustee
and one or more bona fide Bidders (as determined in the respective good faith discretion of MGM MIRAGE or the Trustee provided that no Bidder shall be deemed bona fide if they have not submitted a bid in writing, whether or not conditional) relating
to a possible sale of the Subject Interest (a “Determination”), following reasonable notice to Boyd Sub of such Determination, meetings shall be promptly scheduled to provide a reasonable level of detail and information, including
appropriate documents, data or other materials withheld pursuant to clauses (ii), (iv) and (vi) of the preceding sentence, to each such Bidder’s outside legal counsel, accountants and other professional outside advisors in supervised
data rooms, provided that such outside legal counsel, accountants and other professional outside advisors may not photocopy such documents, data and other materials. Likewise, appropriate officers, employees, representatives and accountants of the
Company shall meet with each such bona fide Bidder to discuss matters related to (iii) above, at a level of detail that is not likely to divulge important trade secrets of the Company, but rather is intended to give a bona fide Bidder an
overview of marketing issues at a level that is customary and appropriate under the circumstances for the evaluation of a purchase of the Subject Interest. 

4. Boyd Sub, and any Affiliates thereof, shall not incur liability to MGM MIRAGE (or any of its Affiliates), the Trust,
any Bidder or any transferee of the Subject Interest from the Trust, in each case, resulting from the provision by MGM MIRAGE of information about the Company or the Subject Interest to Bidders in connection with MGM MIRAGE’s efforts to market
and sell the Subject Interest, except in respect of information provided by Boyd Sub or the Company, and provided, however, that the foregoing shall not waive or limit any liability that Boyd Sub (and Affiliates thereof) may have that is unrelated
to the provision of such information in connection with such efforts to market and sell. 
  

 3 








 5. Subject to the occurrence of the Transfer of the Subject Interest to the
Trust (the “Effective Time”). MGM MIRAGE agrees as follows: 
 (a) if, concurrently with or
following the occurrence of a Specified Distribution (as hereinafter defined) and prior to the sale of the Subject Interest by the Trust, the Trust shall have received a cash distribution from the Company of Distributable Cash in an amount not less
than $10,000,0000 (a “Trust Distribution”). MGM MIRAGE agrees that the Trust shall provide for $10,000,0000 to be paid to Boyd Sub; and 

(b) following the sale of the Subject Interest by the Trust and the remittance of the proceeds of such sale to MGM MIRAGE
or MR Sub, MGM MIRAGE shall cause the Subject Amount (as hereinafter defined) to be paid to Boyd Sub. The “Subject Amount” shall mean: (i) if a Trust Distribution shall not have been received by the Trust, an amount equal to
the greater of (A) the Net Proceeds Portion (as hereinafter defined) and (B) $10,000,000; and (ii) if a Trust Distribution shall have been received by the Trust, an amount (if any) equal to the positive number excess (if any) of the
Net Proceeds Portion minus $10,000,000. The “Net Proceeds Portion” shall mean an amount equal to three percent (3%) of the cash sale price proceeds received by MGM MIRAGE or MR Sub from a sale of the Subject Interest by the
Trust. 
 6. Subject to the occurrence of, and effective upon, the Effective Time, the Operating Agreement is
hereby amended as follows:

 7 








 (s) The second and third sentences of Section 11.2(d) of the Operating
Agreement are restated to read in their entirety as follows: 
 “All Transfers shall contain an agreement of
the transferee to accept the Transfer and to accept and adopt all of the applicable provisions of this Agreement. The Member making a Permitted Transfer shall execute, acknowledge and deliver all such documents and instruments as may be necessary or

entirety as follows: 
 “, provided that the Member wishing to Transfer its Interest (the “Initiating
