In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to September 15, 2026 (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to September 15, 2026 on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Date preceding the Redemption Date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, September 15, 2026, as applicable. If there is no United States Treasury security maturing on September 15, 2026, but there are two or more United States Treasury securities with a maturity date equally distant from September 15, 2026, one with a maturity date preceding September 15, 2026 and one with a maturity date following September 15, 2026, we shall select the United States Treasury security with a maturity date preceding September 15, 2026. If there are two or more United States Treasury securities maturing on September 15, 2026 or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

(a) Other than as provided in Section 5.1(c) below, neither the Company nor any Subsidiary Guarantor will, directly or indirectly, issue, assume or guarantee any Indebtedness secured by a Lien upon any Principal Property or on any evidences of Indebtedness or shares of capital stock of, or other ownership interests in, any Subsidiaries that own any Principal Property (regardless of whether the Principal Property, Indebtedness, capital stock or ownership interests were acquired before or after the date hereof) without effectively providing that all of the Notes or Guarantees then outstanding, as the case may be, shall be secured equally and ratably with (or prior to) the Indebtedness so long as such Indebtedness shall be so secured, except that this restriction will not apply to:

(i) Liens existing on the date of original issuance of the Notes;

(ii) Liens affecting property of a corporation or other entity existing at the time it becomes a Subsidiary Guarantor or at the time it is merged into or consolidated with the Company or a Subsidiary Guarantor (provided that such Liens do not extend to or cover property of the Company or any Subsidiary Guarantor other than property of the entity so acquired or which becomes a Subsidiary Guarantor);

(iii) Liens (including purchase money Liens) existing at the time of acquisition thereof on property acquired after the date hereof or to secure Indebtedness Incurred prior to, at the time of, or within 24 months after the acquisition for the purpose of financing all or part of the purchase price of property acquired after the date hereof (provided that such Liens do not extend to or cover any property of the Company or any Subsidiary Guarantor other than the property so acquired);

(iv) Liens on any property to secure all or part of the cost of improvements or construction thereon or Indebtedness Incurred to provide funds for such purpose in a principal amount not exceeding the cost of such improvements or construction;

-11-

(v) Liens which secure Indebtedness of a Subsidiary of the Company to the Company or to a Subsidiary Guarantor or which secure Indebtedness of the Company to a Subsidiary Guarantor;

(vi) Liens on the stock, partnership or other equity interest of the Company or a Subsidiary Guarantor in any Joint Venture or any Subsidiary that owns an equity interest in such Joint Venture to secure Indebtedness, provided the amount of such Indebtedness is contributed and/or advanced solely to such Joint Venture;

(vii) Liens to government entities, including pollution control or industrial revenue bond financing;

(viii) Liens required by any contract or statute in order to permit the Company or a Subsidiary of the Company to perform any contract or subcontract made by it with or at the request of a governmental entity;

(ix) mechanic’s, materialman’s, carrier’s or other like Liens, arising in the ordinary course of business;

(x) Liens for taxes or assessments and similar charges;

(xi) zoning restrictions, easements, licenses, covenants, reservations, restrictions on the use of real property and other minor irregularities of title; and

(xii) any extension, renewal, replacement or refinancing of any Indebtedness secured by a Lien permitted by any of the foregoing clauses (i) through (xi).

(b) Notwithstanding the foregoing,

(i) if any of the Existing Senior Notes are hereafter secured by any Liens on any of the assets of the Company or any Subsidiary Guarantor (the “Initial Liens”), then the Company and the Subsidiary Guarantor shall, substantially concurrently with the granting of such Liens, subject to such Liens having been approved by all applicable Gaming Authorities to the extent the Gaming Laws of the applicable jurisdiction require such approval, grant perfected Liens in the same collateral to secure the Notes (or Guarantees, as the case may be), equally, ratably and on a pari passu basis (the “Pari Passu Liens”). The Pari Passu Liens granted pursuant to this provision shall be (A) granted concurrently with the granting of any such Liens, and (B) granted pursuant to instruments, documents and agreements which are no less favorable to the Trustee and the Holders of the Notes than those granted to secure the Existing Senior Notes. In connection with the granting of any such Pari Passu Liens, the Company and each Subsidiary Guarantor shall provide to the Trustee (y) policies of title insurance on customary terms and conditions, to the extent that policies of title insurance on the corresponding property are provided to the Holders of the Existing Senior Notes or their respective trustee (and in an insured amount that bears the same proportion to the principal amount of the outstanding Notes as the insured amount in the policies provided to the holders of the Existing Senior Notes bears to the aggregate outstanding amount of the Existing Senior Notes), and (z) legal opinions and other assurances as the Trustee may reasonably request; and

-12-

(ii) if the Company and the Subsidiary Guarantors become entitled to the release of any Initial Liens securing the Existing Senior Notes and Subsidiary Guarantees related thereto, and provided that no Default or Event of Default has then occurred and remains continuing, the Company and the Subsidiary Guarantors may in their sole discretion request that the collateral agent release any such Lien securing the Notes, the Existing Senior Notes and such other notes and guarantees, and in such circumstances the collateral agent (or the Trustee) shall so release such Initial Liens.

(c) Notwithstanding the foregoing, the Company or any Subsidiary Guarantor may create, assume or suffer to exist Liens not otherwise permitted as described above, provided that at the time of such incurrence, assumption or sufferance, after giving effect to such Lien, the sum of outstanding Indebtedness secured by such Liens (not including Liens permitted under Section 5.1(a) above) plus all Attributable Debt in respect of Sale and Lease-Back Transactions entered into (not including Sale and Lease-Back Transactions permitted under Section 5.2(a) below), measured, in each case, at the time the Lien is incurred, does not exceed 15% of Consolidated Net Tangible Assets and Liens securing Indebtedness in excess of such amount to the extent such Lien is incurred in connection with an extension, renewal, replacement or refinancing of Indebtedness (not to exceed the principal amount of such extended, renewed, replaced or refinanced Indebtedness plus fees, expenses and premium payable thereon) secured by a Lien incurred pursuant to the provisions of this Section 5.1(c) or any previous extension, renewal, replacement or refinancing of any such Indebtedness (which extended, renewed, replaced or refinanced Indebtedness shall, for the avoidance of doubt, thereafter be included in the calculation of such amount), provided that the foregoing shall not apply to any Liens that may at any time secure any of the Existing Senior Notes.

SECTION 5.2. Limitation on Sale and Lease-Back Transactions.

(a) Other than as provided in Section 5.2(b) below, neither the Company nor any Subsidiary Guarantor will enter into any Sale and Lease-Back Transaction, unless either:

(i) the Company or such Subsidiary Guarantor would be entitled, pursuant to the provisions described in clauses (i) through (xii) of Section 5.1(a) above, to create, assume or suffer to exist a Lien on the property to be leased without equally and ratably securing the Notes;

(ii) such Sale and Lease-Back Transaction is executed at the time of, or within 12 months after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation of the applicable Principal Property;

(iii) an amount equal to the net cash proceeds of such sale is applied within 180 days to the retirement, discharge, repurchase, repayment or prepayment of its Funded Debt; or

(iv) an amount equal to the net cash proceeds of such sale is applied within 180 days to the purchase, construction, development, expansion or improvement of other property.

(b) Notwithstanding the restrictions set forth in Section 5.1 and Section 5.2 (a), the Company or any Subsidiary Guarantor may enter into Sale and Lease-Back Transactions not otherwise permitted as described above, provided that at the time of entering into such Sale and Lease-Back Transaction, after giving effect to such Sale and Lease-Back Transaction, the sum of outstanding Indebtedness secured by Liens (not including Liens permitted under Sections 5.1(a) and 5.1(b) above) plus all Attributable Debt in respect of Sale and Lease-Back Transactions entered into (not including Sale and Lease-Back Transactions permitted under Section 5.2(a) above), measured, in each case, at the time any such Sale and Lease-Back Transaction is entered into, does not exceed 15% of Consolidated Net Tangible Assets and Liens securing Indebtedness in excess of such amount to the extent such Lien is incurred in connection with an extension, renewal, replacement or refinancing of Indebtedness (not to exceed the principal amount of such extended, renewed, replaced or refinanced Indebtedness plus fees,

-13-

expenses and premium payable thereon) secured by a Lien incurred pursuant to the provisions of this Section 5.2(b) or any previous extension, renewal or replacement or refinancing of any such Indebtedness (which extended, renewed, replaced or refinanced Indebtedness shall, for the avoidance of doubt, thereafter be included in the calculation of such amount), provided that the foregoing shall not apply to any Liens that may at any time secure any of the Existing Senior Notes.

SECTION 5.3. Guarantee.

(a) The Company shall (i) cause each domestic Subsidiary of the Company that is a guarantor of Reference Indebtedness (other than MGM Yonkers and any other Subsidiary Guarantor subject to the oversight of the New York State Gaming Commission, unless and until New York Gaming Approval is obtained, and, with respect to MDDC and MDDHC, unless and until New Jersey Gaming Approval is obtained) to become on the Issue Date or, if such Subsidiary was not a guarantor of Reference Indebtedness as of the Issue Date but thereafter becomes a guarantor of Reference Indebtedness (whether or not such Subsidiary is acquired or created after the Issue Date) and is wholly-owned, directly or indirectly, by the Company (a “Wholly-Owned Subsidiary”), at the time such Wholly-Owned Subsidiary guarantees any Reference Indebtedness, a guarantor of the obligations of the Company under this Indenture and the Notes by executing this Indenture (directly, by supplemental indenture or by a joinder agreement, a form of which is attached hereto as Exhibit II) as a Subsidiary Guarantor or by executing a Guarantee pursuant to Section 1102 of the Base Indenture, as supplemented by this Second Supplemental Indenture; provided that any newly created or acquired Subsidiary that requires approval from a Gaming Authority in order to execute and deliver a Guarantee shall not be required to execute and deliver such Guarantee unless and until it receives the required approval from the applicable Gaming Authority, and shall execute and deliver the Guarantee in accordance with the provisions of this Section 5.3(a) upon receipt of approval from the applicable Gaming Authority; and provided further that the provision of a Guarantee by a Wholly-Owned Subsidiary after the Issue Date shall be subject to compliance with any applicable Gaming Laws and the Company agrees that (subject to Section 5.3(b)) it shall not have any such Wholly-Owned Subsidiary become a guarantor of Reference Indebtedness unless it is permitted to give such Guarantee under applicable Gaming Laws); and (ii) deliver to the Trustee an Opinion of Counsel that such Guarantee is the valid, binding and enforceable obligation of such Subsidiary Guarantor, subject to customary exceptions for bankruptcy, fraudulent transfer and equitable principles.

Notwithstanding the foregoing, for the avoidance of doubt with respect to any Subsidiary existing on the Issue Date that has executed this Second Supplemental Indenture as of the Issue Date but is required to obtain regulatory approval from a Gaming Authority in order to guarantee the Company’s obligations under this Second Supplemental Indenture and the Notes (including New York Gaming Approval, with respect to MGM Yonkers, and New Jersey Gaming Approval, with respect to MDDC and MDDHC), such Subsidiary shall not have any liability for, or be subject to any obligation to guarantee, the Company’s obligations under this Second Supplemental Indenture or the Notes unless and until such Subsidiary receives regulatory approval from the applicable Gaming Authority. Upon the receipt of such regulatory approval from the applicable Gaming Authority, such Subsidiary shall immediately and automatically, without any further action by such Subsidiary or by the Company, be and become a Subsidiary Guarantor for all purposes under this Second Supplemental Indenture and the Notes, subject to, without limitation, all liabilities and obligations of Subsidiary Guarantors described under Section 1101 of the Indenture with respect to the Notes.

(b) The actions set forth in Section 5.3(a) hereof shall be taken within 10 days of the time on which any Person is required to become a Subsidiary Guarantor pursuant to such Section 5.3(a), provided that if such Person is not permitted to give a Guarantee under applicable Gaming Laws, then, such 10-day period shall be extended as long as necessary for the Company to, and the Company shall

-14-

continue to use reasonable best efforts to, obtain the requisite approvals for such Guarantee from the applicable Gaming Authority. If any Subsidiary Guarantor no longer guarantees any Reference Indebtedness at any time, then such Subsidiary Guarantor shall be released from its obligations under its Guarantee, and the Trustee shall execute any documents reasonably required in order to evidence the release of such Subsidiary Guarantor from its obligations under its Guarantee upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such conditions to release such Guarantee have been satisfied.

(c) The Company will not permit any newly acquired or created Wholly-Owned Subsidiary to guarantee any Reference Indebtedness without making effective provision for such Wholly-Owned Subsidiary to become a Subsidiary Guarantor under this Indenture (unless such guarantee is not permitted under applicable Gaming Laws and the Company is complying with Section 5.3(b) hereof).

SECTION 5.4. Reports.

(a) Whether or not required by the Commission, so long as any Notes are outstanding, the Company shall furnish to the Trustee within 15 calendar days after the time periods specified in the Commission’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Company’s independent registered public accounting firm; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports (it being understood that the availability of such information or report on the Commission’s EDGAR service (or any successor thereto) shall be deemed to satisfy the Company’s obligation to furnish the information or report referenced in clauses (a)(1) and (a)(2) of this Section 5.4 to the Trustee).

(b) In addition, whether or not required by the Commission, the Company will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on the Officer’s Certificate described in Section 1004 of the Base Indenture). The Trustee is under no duty to examine such reports, information or documents to ensure compliance with the provisions of this Second Supplemental Indenture or to ascertain the correctness or accuracy of the information or the statements contained therein. The Trustee is entitled to assume such compliance and correctness unless an Officer of the Trustee is informed in writing otherwise.

(b) default in the payment of principal of (or premium, if any, on) the Notes at their Maturity (upon acceleration, optional or mandatory redemption or otherwise); or

(c) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section 501 specifically dealt with), and continuance of such default or breach for a period of 60 calendar days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(d) the acceleration of the maturity of any Indebtedness of the Company or any Subsidiary Guarantor (other than Non-Recourse Indebtedness), at any time, in an amount in excess of the greater of (i) $250,000,000 and (ii) 5% of Consolidated Net Tangible Assets, if such acceleration is not annulled within 30 calendar days after written notice to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes; or

(e) entry of final judgments against the Company or any Subsidiary Guarantor which remain undischarged for a period of 60 days, provided that the aggregate of all such judgments exceeds $250,000,000 and judgments exceeding $250,000,000 remain undischarged for 60 calendar days after written notice to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes; or

If a failure to comply by the Company with Section 5.4 continues for 60 days after the Company receives notice of such failure to comply in accordance with clause (c) of the definition of “Event of Default” (such notice, the “Reports Default Notice”), and is continuing on the 60th day following the Company’s receipt of the Reports Default Notice, the Company will pay liquidated damages to all holders of Notes at a rate per annum equal to 0.25% of the principal amount of the Notes from the 60th day following the Company’s receipt of the Reports Default Notice to but not including the earlier of (x) the 121st day following the Company’s receipt of the Reports Default Notice and (y) the date on which the failure to comply by the Company with Section 5.4 shall have been cured or waived.

If the failure to comply by the Company with Section 5.4 shall not have been cured or waived on or before the 121st day following the Company’s receipt of the Reports Default Notice, then the failure to comply by the Company with Section 5.4 shall on such 121st day constitute an Event of Default. A failure to comply with Section 5.4 automatically shall cease to be continuing and shall be deemed cured at such time as the Company furnishes to the Trustee the applicable information or report (it being understood that the availability of such information or report on the Commission’s EDGAR service (or any successor thereto) shall be deemed to satisfy the Company’s obligation to furnish such information or report to the Trustee).

ARTICLE EIGHT

SATISFACTION AND DISCHARGE

SECTION 8.1. Satisfaction and Discharge.

Article IV of the Base Indenture shall be superseded in its entirety by the following language with respect to, and solely for the benefit of the Holders of the Notes; provided that this Article Eight shall not become part of the terms of any other series of Securities:

Section 401. Satisfaction and Discharge of Indenture.

This Indenture shall, upon Company Request, cease to be of further effect with respect to the Notes (except as to any surviving rights of registration of transfer or exchange of the Notes herein expressly provided for and rights to receive payments of principal (and premium, if any) and interest on the Notes) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when:

(a) either

(i) all Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, and (y) Notes the payment for which money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

(ii) all Notes not theretofore delivered to the Trustee for cancellation,

(1) have become due and payable, or

(2) will become due and payable at their Stated Maturity within one year, or

(3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company;

(b) the Company, in the case of subclause (2) or (3) of clause (a)(ii) of this Section 401, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount sufficient to pay and discharge the entire Indebtedness on such Notes for principal (and premium, if any) and interest to the date of such deposit (in the case of Notes which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the federal bankruptcy laws, as now or hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the deposited money to the Company, the obligations of the Company under this Indenture with respect to such Notes shall not be deemed terminated or discharged;

(c) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

-19-

(d) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Company to any authenticating agent hereunder, the obligations of the Company under Section 1001, and, if money shall have been deposited with the Trustee pursuant to clause (b) of this Section, the obligations of the Trustee under Section 606 (until payments are made by the Trustee thereunder) and the last paragraph of Section 1003 shall survive.

Section 402. Application of Trust Money.

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Notes, and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Company may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee.

Section 403. Applicability of this Article.

Except as otherwise provided in Section 404, the Company may terminate its obligations under the Notes and this Indenture as set forth in Section 404.

Section 404. Defeasance upon Deposit of Moneys or U.S. Government Obligations.

At the Company’s option, either (x) the Company shall be deemed to have been Discharged (as defined below) from its obligations with respect to Notes and the Subsidiary Guarantors shall be deemed to have been discharged from their obligations under their Guarantees in respect of the Notes (“legal defeasance option”) or (y) the Company shall cease to be under any obligation to comply with any term, provision or condition set forth in Article VIII and Section 1004, and Sections 5.1, 5.2 and 5.3 of the Second Supplemental Indenture with respect to Notes and the Subsidiary Guarantors shall cease to be under any obligation to comply with any term, provision or condition set forth in Section 1111 (or comparable provisions of its Guarantee if not set forth in Article XI) with respect to their Guarantees in respect of the Notes (“covenant defeasance option”) at any time after the applicable conditions set forth below have been satisfied:

(e) The Company shall have deposited or caused to be deposited irrevocably with the Trustee as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Notes (i) money in an amount, or (ii) U.S. Government Obligations (as defined below) which through the payment of interest and principal in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of items (i) and (ii), sufficient, in the opinion (with respect to items (i) and (ii)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal (including any mandatory sinking fund payments) of and premium, if any, and interest on, the outstanding Notes on the dates such installments of interest or principal and premium are due;

-20-

(f) Such deposit shall not cause the Trustee to have a conflicting interest as defined in Section 608 and for purposes of the TIA;

(g) Such deposit will not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Company or any Subsidiary Guarantor is a party or by which it is bound;

(h) If the Notes are then listed on any national securities exchange, the Company shall have delivered to the Trustee an Opinion of Counsel or a letter or other document from such exchange to the effect that the Company’s exercise of its option under this Section 404 would not cause such Notes to be delisted;

(i) No Event of Default or Default shall have occurred and be continuing on the date of such deposit and, with respect to the legal defeasance option only, no Event of Default under Section 501(f) or Section 501(g) or event which with the giving of notice or lapse of time, or both, would become an Event of Default under Section 501(f) or Section 501(g) shall have occurred and be continuing on the 91st day after such date;

(j) The Company shall have delivered to the Trustee an Opinion of Counsel or a ruling from the Internal Revenue Service to the effect that the beneficial owners of the Notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such deposit, defeasance or Discharge.

The Company shall pay interest semi-annually in arrears on March 15 and September 15 of each year commencing on March 15, 2025.

Holders must surrender Notes to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, all payments in respect of this Note (including principal, premium, if any, and interest) must be made by wire transfer of immediately available funds to the accounts specified by the Holder hereof.

Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture.

5. OPTIONAL REDEMPTION; MANDATORY DISPOSITION PURSUANT TO GAMING LAWS

(a) On and after September 15, 2026, the Company may on any one or more occasions redeem the Notes, in whole or in part, upon not less than 10 nor more than 60 days’ notice mailed or otherwise delivered to each holder of Notes in accordance with the applicable procedures of DTC, at the redemption prices (expressed as a percentage of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest on the Notes, if any, to the applicable date of redemption, if redeemed during the twelve-month period beginning on September 15 of each of the years indicated below:

Year	Percentage
2026		103.063	%
2027		101.531	%
2028 and thereafter		100.000	%

(b) In addition, the Notes are redeemable at the election of the Company, in whole or in part, at any time or from time to time prior to September 15, 2026, at a redemption price (the “Redemption Price”) equal to the greater of:

(i) 100% of the principal amount of the Notes to be redeemed; or

(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on September 15, 2026) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points less (b) interest accrued to the date of redemption,

plus, in either of the above cases, accrued and unpaid interest to the Redemption Date on the Notes to be redeemed.

(c) Prior to September 15, 2026, the Company may also on any one or more occasions redeem in the aggregate up to 40% of the aggregate principal amount of the Notes (calculated after giving effect to any issuance of additional notes under the Indenture) with the net cash proceeds of one or more Equity Offerings, upon not less than 10 nor more than 60 days’ notice mailed or otherwise delivered to each Holder in accordance with the applicable procedures of DTC, at a redemption price equal to 106.125% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to the Redemption Date; provided that:

(i) at least 50% of the original aggregate principal amount of the Notes remains outstanding after each such redemption; and

(d) Except as described in this paragraph 5, the Notes shall not be redeemable at the Company’s option prior to September 15, 2026.

I-6

6. NOTICES OF REDEMPTION

Notices of redemption shall be mailed by first-class mail or otherwise delivered at least 10 (unless a shorter notice is acceptable to the Trustee) days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address all in accordance with the Indenture. Any notice to Holders of Notes of a redemption will state, among other things, the redemption price (or how the redemption price will be calculated if not a fixed amount or subject to change) and date. A notice of redemption may provide that the optional redemption described in such notice is conditioned upon the occurrence of certain events before the Redemption Date. Such notice of conditional redemption will be of no effect unless all such conditions to the redemption have occurred before the Redemption Date or have been waived the Company. If any of such events fail to occur and are not waived by the Company, the Company shall be under no obligation to redeem the Notes or pay the Holders any redemption proceeds and the Company’s failure to redeem the Notes shall not be considered a default or an Event of Default. If less than all of the Notes are to be redeemed at any time (other than pursuant to paragraph 5 above) the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Notes not previously called for redemption, consistent with the procedures of DTC. On and after the Redemption Date, interest ceases to accrue on Notes or portions of them called for redemption.

In connection with any tender offer or other offer to purchase for all of the Notes, if holders of not less than 90% of the aggregate principal amount of the then outstanding Notes validly tender and do not validly withdraw such Notes in such tender offer and the Company, or any third party making such tender offer in lieu of the Company, purchases all of the Notes validly tendered and not validly withdrawn by such holders, the Company or such third party will have the right, upon not less than 10 nor more than 60 days’ notice following such purchase date, to redeem all Notes that remain outstanding following such purchase at a price equal to the price paid to each other holder in such tender offer, plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the date of such redemption.

7. DENOMINATIONS; TRANSFER; EXCHANGE

The Notes are in registered form without coupons in minimum denominations of $2,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 calendar days before the day of any selection of Notes for redemption and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

8. PERSONS DEEMED OWNERS

The registered Holder of this Note may be treated as the owner of it for all purposes.

9. UNCLAIMED MONEY

If money for the payment of principal or interest remains unclaimed for two years, the Paying Agent shall pay the money back to the Company at its request, or if then held by the Company or a domestic Subsidiary, shall be discharged from such trust (unless an abandoned property law designates another Person for payment thereof). After any such payment, Holders entitled to the money must look only to the Company for payment thereof, and all liability of the Paying Agent with respect to such money, and all liability of the Company or such permitted Subsidiary as trustee thereof, shall thereupon cease.

I-7

10. DISCHARGE AND DEFEASANCE

Subject to certain conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Indenture with respect to the Notes if, among other things, the Company deposits with the Trustee funds for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

11. AMENDMENT, WAIVER

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. The Indenture also contains provisions, with certain exceptions as therein provided, permitting the Holders of a majority in principal amount of the Notes at the time outstanding, on behalf of the Holders of all such Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. The Indenture also permits certain other amendments, modifications or waivers thereof only with the consent of all affected Holders of the Notes, while certain other amendments or modifications may be made without the consent of any Holders of Notes. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. The right of any Holder of a Note (or such Holder’s duly designated proxy) to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of Notes as of a date set by the Company and identified by the Trustee in a notice furnished to Holders of the Notes in accordance with the terms of the Indenture.

12. DEFAULTS AND REMEDIES

Events of Default are set forth in the Indenture. If an Event of Default shall have occurred and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of, premium, if any, and accrued interest on all the Notes to be due and payable by notice in writing to the Company and, if given by the Holders, to the Trustee, specifying the respective Events of Default, and the same shall become immediately due and payable.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal, premium, if any, or interest) if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interest of the Holders.

I-8

Notwithstanding clause (c) of the definition of “Event of Default” in the Indenture or any other provision of the Indenture, except as provided in the final sentence of this paragraph, the sole remedy for any failure to comply by the Company with Section 5.4 of the Indenture shall be the payment of liquidated damages as described in the following sentence, such failure to comply shall not constitute an Event of Default, and holders of the Notes shall not have any right under the Indenture or the Notes to accelerate the maturity of the Notes as a result of any such failure to comply. If a failure to comply by the Company with Section 5.4 of the Indenture continues for 60 days after the Company receives notice of such failure to comply in accordance with clause (c) of the definition of “Event of Default” in the Indenture (such notice, the “Reports Default Notice”), and is continuing on the 60th day following the Company’s receipt of the Reports Default Notice, the Company will pay liquidated damages to all holders of Notes at a rate per annum equal to 0.25% of the principal amount of the Notes from the 60th day following the Company’s receipt of the Reports Default Notice to but not including the earlier of (x) the 121st day following the Company’s receipt of the Reports Default Notice and (y) the date on which the failure to comply by the Company with Section 5.4 of the Indenture shall have been cured or waived. On the earlier of the date specified in the immediately preceding clauses (x) and (y), such liquidated damages will cease to accrue. If the failure to comply by the Company with Section 5.4 of the Indenture shall not have been cured or waived on or before the 121st day following the Company’s receipt of the Reports Default Notice, then the failure to comply by the Company with Section 5.4 of the Indenture shall on such 121st day constitute an Event of Default. A failure to comply with Section 5.4 of the Indenture automatically shall cease to be continuing and shall be deemed cured at such time as the Company furnishes to the Trustee the applicable information or report (it being understood that the availability of such information or report on the Commission’s EDGAR service (or any successor thereto) shall be deemed to satisfy the Company’s obligation to furnish such information or report to the Trustee).

13. TRUSTEE DEALINGS WITH THE COMPANY

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

14. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

No past, present or future director, officer, employee, stockholder or incorporator, as such, of the Company or any successor corporation shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

15. GOVERNING LAW

THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

16. AUTHENTICATION
