2.2 The obligations of Completion Guarantor hereunder are independent of and in addition to any other obligations of Completion Guarantor relating to the Company or CityCenter. For the avoidance of doubt, no other equity or debt investments made by Completion Guarantor or any of its Subsidiaries in the Company or any of its Subsidiaries or other payments made by Completion Guarantor or its Subsidiaries to or for the benefit of the Company or any of its Subsidiaries shall reduce or otherwise affect the amount of funds available to be drawn under this Guarantee.

2.3 It is acknowledged and agreed that (a) Completion Guarantor retains all of its rights as surety in respect of all amounts paid by Completion Guarantor under the Existing Completion Guarantee and to be paid under this Guarantee to the extent that such amounts are Cost Overruns, including the right to receive MGM Completion Guarantee Reimbursement Amount solely as and when permitted by the terms of the agreements and instruments under which the Secured Obligations arise; provided, however, that Completion Guarantor shall in no manner be entitled to assert those rights against CityCenter or the Company (except solely with respect to the MGM Completion Guarantee Reimbursement Amount and solely as and when permitted by the terms of the agreements and instruments under which the Secured Obligations arise) unless and until there has been a Discharge of all Secured Obligations, and (b) subject in all respects to the agreements and instruments under which the Secured Obligations arise, Completion Guarantor shall be entitled to require the application of Condo Proceeds in the amount of $123,850,553 to the payment of remaining Completion Costs (as and when received), to have such amounts retained in the Sponsor Proceeds Account for the satisfaction of the Completion Costs or, following the satisfaction of all Completion Costs and subject to the terms of the agreements and instruments under which the Secured Obligations arise, to be remitted to Completion Guarantor in satisfaction of any MGM Completion Guarantee Reimbursement Amount then owing.

2.4 Without limiting the generality of Section 3.1 hereof or of any of the other provisions of this Guarantee, should there be insufficient moneys in the Sponsor Proceeds Account in order to fund the Security Balance Account for the payment of any Completion Costs then due and owing, Completion Guarantor shall be obligated, without any prior demand or other

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

action being required from or by any of the Beneficiaries, to promptly fund into the Sponsor Proceeds Account to cure any such deficiency.

3. Guarantee Enforcement.

3.1 If the Completion Guarantor fails to pay amount owing hereunder when due, the Enforcement Collateral Agent may (but shall not be required to) make demand hereunder upon the presentation of supporting documentation for any Completion Costs (or amounts under Section 19) then due and owing, and any such demand shall be payable by Completion Guarantor within ten (10) Business Days by wire transfer of immediately available funds to the Company for direct deposit into the Sponsor Proceeds Account and from such account, then disbursed for the name of the Company in payment of such Completion Costs; provided, however, that no such demand shall be made in respect of the Pending Mechanics Lien Claims unless and until a final, unstayed order or judgment has been entered in the Perini Lawsuit. Subject to the proviso in the preceding sentence relating to the Pending Mechanics Lien Claims, should Completion Guarantor default or otherwise fail to comply with such demand, the Enforcement Collateral Agent thereafter may (but shall not be required to) seek, compel, or recover with respect to such failure, the performance of such obligation pursuant to any right, power, and/or remedy available under this Guarantee, the Circus Deeds of Trust or the operative agreement(s) governing the Permitted Cash Collateral Substitution (as defined below) (as applicable), and/or applicable law. Any recovery obtained by the Enforcement Collateral Agent in such instance shall be directed to the satisfaction of such Completion Costs and not to the payment of any of the Secured Obligations except solely in the event and to the extent that the Beneficiaries in any manner whatsoever (including through protective advances, the application of collateral proceeds, or otherwise) satisfied or can be deemed to have satisfied the Completion Costs subject to such demand. In such event (and to such extent), the proceeds of such recovery shall be distributed (a) in the case of Completion Costs paid or otherwise satisfied through protective advances, to the Beneficiaries making such protective advances, and (b) in the case of Completion Costs paid or otherwise satisfied through the application of collateral proceeds, pursuant to the provisions of the Intercreditor Agreements as if such proceeds otherwise constituted collateral proceeds.

3.2 Completion Guarantor agrees that its obligations hereunder shall not be affected by any exercise or non-exercise of remedies by any Beneficiary, and that this Guarantee shall continue to be enforceable against Completion Guarantor until it terminates in accordance with Section 31. Completion Guarantor’s obligations hereunder in accordance with the terms hereof shall be irrevocable and unconditional, including notwithstanding any (x) deterioration in the financial condition of the Company, including any bankruptcy or similar proceeding of the Company or any of its subsidiaries, (y) elimination or transfer of Completion Guarantor’s ownership interest in the Company, including in connection with any bankruptcy or similar proceeding or (z) any deemed satisfaction of (or any failure by Dubai World to fund any of) Dubai World’s obligations under the Dubai World Completion Guarantee.

3.3 Notwithstanding any other provision of this Guarantee to the contrary, this Guarantee is not a guarantee of any of the Secured Obligations (including any Indebtedness thereunder).

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

3.4 Completion Guarantor may effect its funding obligations hereunder through fundings by itself or one or more of its direct or indirect Subsidiaries. Without affecting any different arrangement between Dubai World and Guarantor, insofar as their relationship as members of the Company may be concerned, each funding made pursuant to this Guarantee (whether made by Sponsor directly or through a Subsidiary) shall be deemed to constitute a contribution to the equity capital of the Company, except to the extent of (a) the obligations of the Company with respect to the MGM Completion Guarantee Reimbursement Amount and (b) the Completion Guarantor’s rights in and to the Condo Proceeds.

4. Security for Guarantee.

4.1 This Guarantee is secured by the Circus Deeds of Trust pertaining to the real and personal property described therein (the “Collateral”). In the event that the Enforcement Collateral Agent exercises its rights with respect to the Collateral as provided herein and in the Circus Deeds of Trust, the parties agree, without in any manner limiting the scope of this Completion Guaranty or the rights in the Collateral, that the proceeds of the Collateral shall be deemed to be applied first to satisfy Completion Guarantor’s obligations under this Guarantee with respect to the first $300,000,000 of Completion Costs required to be paid under the provisions of this Guarantee and then, to satisfy the remaining Completion Costs. Without limiting the generality of the other provisions of this Guarantee, in the event of the occurrence of any event of default under the Circus Deeds of Trust that, in the reasonable judgment of the Enforcement Collateral Agent, impairs the value of the Collateral in an amount not less than $25,000,000, the Beneficiaries shall be deemed to have an accelerated obligation under this Guarantee in the amount of the Enforcement Collateral Agent’s estimate of Completion Guarantor’s liability under this Guarantee (which in no circumstances shall be less than (a) $300,000,000 prior to the final resolution, whether via adjudication pursuant to a final and nonappealable order or judgment of a court of competent jurisdiction, payment, or settlement, of all claims at issue in the Perini Lawsuit (“Perini Lawsuit Resolution”) and (b) $50,000,000 subsequent to the Perini Lawsuit Resolution), and the Enforcement Collateral Agent shall be entitled, but not obligated, and may act (or refrain from acting) as it determines in its sole and absolute discretion, to pursue a foreclosure of the Circus Deeds of Trust (and/or any of them or any combination of them) if the Release of the Circus Deeds of Trust has not occurred and/or to pursue any other rights, powers, and/or remedies under the Circus Deeds of Trust (if the Release of the Circus Deeds of Trust has not occurred), this Guarantee, and/or applicable law.

4.2 Upon the final resolution, whether by adjudication pursuant to a final and nonappealable order or judgment of any court of competent jurisdiction, payment, or settlement of (a) all Pending Mechanics Lien Claims, (b) all Other Pending Construction Claims, and (c) all Remaining Construction Costs, Completion Guarantor may obtain the release of the Circus Deeds of Trust (the “Release of the Circus Deeds of Trust”) by substituting cash collateral (the “Permitted Cash Collateral Substitution”) in an amount equal to the remaining aggregate amount of (a) the OCIP Insurance Payables and (b) the Crystals TA Expenses as estimated and certified by a Responsible Officer of Completion Guarantor and to the satisfaction of the Credit Agreement Collateral Agent (or should there have been a Discharge of the Credit Agreement Obligations, of the Enforcement Collateral Agent), such cash collateral to be deposited with the

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

Credit Agreement Collateral Agent (or should there have been a Discharge of the Credit Agreement Obligations, with the Enforcement Collateral Agent) pursuant to pledge, deposit account, or similar agreements in form and substance acceptable to the Credit Agreement Collateral Agent (or should there have been a Discharge of the Credit Agreement Obligations, to the Enforcement Collateral Agent), it being understood that the purpose of the Permitted Cash Collateral Substitution is to secure the Completion Guarantor’s obligation to satisfy the then-remaining OCIP Insurance Payables and Crystals TA Expenses and that no Release of the Circus Deeds of Trust shall occur unless and until the Permitted Cash Collateral Substitution (including the resolution of all issues relating to the acceptability of the form and substance of any pertinent pledge, deposit account, or similar agreement) shall have occurred. Notwithstanding any other provision of this Guarantee to the contrary, such cash collateral may consist of Condo Proceeds to the extent expressly permitted pursuant to the provisions of the Amended and Restated Credit Agreement, the Additional First Lien Agreement, and the Junior Lien Indenture. In the event that Completion Guarantor may obtain the Release of the Circus Deeds of Trust pursuant to the provisions of this Section 4.2, the Credit Agreement Collateral Agent (or should there have been a Discharge of the Credit Agreement Obligations, the Enforcement Collateral Agent) shall be authorized (and shall be deemed to have been granted an irrevocable power of attorney by the Beneficiaries) to execute all documents necessary to effect such release without any further action being required on the part of the other Beneficiaries. Notwithstanding any other provisions of this Guarantee to the contrary, the Release of the Circus Deeds of Trust and the Permitted Cash Collateral Substitution shall in no manner constitute a defeasance (or other type of discharge) of Completion Guarantor with respect to any Guaranteed Obligations (including any Completion Costs) remaining unpaid as of (or arising after) the date of the Release of the Circus Deeds of Trust.

5. Nature of Guarantee. This Guarantee is irrevocable and continuing in nature and relates to any Guaranteed Obligations now existing or hereafter arising. This Guarantee is a guarantee of prompt and punctual payment and performance and is not merely a guarantee of collection.

6. Relationship to Other Agreements. Except as specifically noted herein, nothing herein shall in any way modify or limit the effect of terms or conditions set forth in any other transaction document, including without limitation the Sponsor Subordination Agreement, executed by Completion Guarantor or any other document, instrument or agreement executed by Completion Guarantor in connection with CityCenter, but each and every term and condition hereof shall be in addition thereto.

7. Subordination of Indebtedness of the Company to Completion Guarantor. Completion Guarantor represents and warrants that, as of the date hereof, the Company and its Subsidiaries do not have any Indebtedness owing to Completion Guarantor other than the portion of the Sponsor Subordinated Debt that has already been advanced to the Company in connection with funding construction of CityCenter or as otherwise expressly provided or permitted in the Amended and Restated Credit Agreement, the Additional First Lien Agreement, and the Junior Lien Indenture (it being acknowledged that the MGM Completion Guarantee Reimbursement Amount and the right of MGM Resorts to receive Condo Proceeds in the amounts described above do not constitute Indebtedness). Completion Guarantor hereby agrees that all

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

Indebtedness now or hereafter owed by the Company or any of its Subsidiaries to Completion Guarantor or any of its Subsidiaries shall be subordinated in right of payment to the Secured Obligations as and to the extent provided in the Sponsor Subordination Agreement, the Amended and Restated Credit Agreement, the Additional First Lien Agreement, or the Junior Lien Indenture (as applicable), and all such present or future Indebtedness of the Company or any of its Subsidiaries shall be subject to the Sponsor Subordination Agreement.

8. Statutes of Limitations and Other Laws. Until the Guaranteed Obligations have been paid and performed in full or this Guarantee terminates in accordance with Section 31, all the rights, privileges, powers and remedies granted to the Beneficiaries hereunder shall continue to exist and may be exercised by the Beneficiaries at any time and from time to time irrespective of the fact that any of the Guaranteed Obligations or the Secured Obligations may have become barred by any statute of limitations. Completion Guarantor expressly waives the benefit of any and all statutes of limitation, and any and all Laws providing for exemption of property from execution or for evaluation and appraisal upon foreclosure, to the maximum extent permitted by applicable Laws.

9. Waivers and Consents. Completion Guarantor consents and agrees that the Beneficiaries may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (a) supplement, modify, amend, extend, renew, accelerate or otherwise change the time for payment or the terms of their respective Secured Obligations or any part thereof, including, without limitation, any increase or decrease of the rate(s) of interest thereon and any increase or decrease in the principal amount of their respective Secured Obligations; (b) supplement, modify, amend or waive, or enter into or give any agreement, approval or consent with respect to, their respective Secured Obligations or any part thereof, or any of the transaction documents to which Completion Guarantor is not a party or any additional security or guarantees, or any condition, covenant, default, remedy, right, representation or term thereof or thereunder; (c) accept new or additional instruments, documents or agreements in exchange for or relative to any of the transaction documents or their respective Secured Obligations or any part thereof; (d) accept partial payments on the Secured Obligations; (e) receive and hold additional security or guarantees for their respective Secured Obligations or any part thereof; (f) release, reconvey, terminate, waive, abandon, fail to perfect, subordinate, exchange, substitute, transfer and/or enforce any security or guarantees, and apply any security and direct the order or manner of sale thereof as the Beneficiaries in their discretion may determine; (g) release any Person from any personal liability with respect to their respective Secured Obligations or any part thereof; (h) settle, release on terms satisfactory to the applicable Beneficiary or by operation of applicable Laws or otherwise liquidate or enforce any of their respective Secured Obligations and any security or guarantee therefor in any manner, consent to the transfer of any security and bid and purchase at any sale; and/or (i) consent to the merger, change or any other restructuring or termination of the corporate or other existence of the Company or any other Related Party, and correspondingly restructure their respective Secured Obligations, and any such merger, change, restructuring or termination shall not affect the liability of Completion Guarantor or the continuing effectiveness hereof, or the enforceability hereof with respect to all or any part of the Guaranteed Obligations.

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

The Enforcement Collateral Agent, on behalf of the Beneficiaries, may enforce this Guarantee independently of any other remedy or security the Beneficiaries at any time may have or hold in connection with their respective Secured Obligations. Completion Guarantor expressly waives any right to require the Beneficiaries to marshal assets in favor of the Company, Completion Guarantor or any other Person, and agrees that the Beneficiaries may proceed against the Company or any other Person, or upon or against any security or remedy, before proceeding to enforce this Guarantee, in such order as they shall determine in their discretion. The Enforcement Collateral Agent, on behalf of the Beneficiaries, may file a separate action or actions against the Company and/or Completion Guarantor without respect to whether action is brought or prosecuted with respect to any security or against any other Person, or whether any other Person is joined in any such action or actions. Completion Guarantor agrees that the Beneficiaries and the Company and any Affiliates of the Company may deal with each other in connection with their respective Secured Obligations or otherwise, or alter any contracts or agreements now or hereafter existing between any of them, in any manner whatsoever, all without in any way altering or affecting the effectiveness and enforceability of this Guarantee. The Beneficiaries’ rights hereunder shall be reinstated and revived, and the enforceability of this Guarantee shall continue, with respect to any amount at any time paid on account of the Guaranteed Obligations which thereafter shall be required to be restored or returned by the Beneficiaries upon the bankruptcy, insolvency or reorganization of the Company, Completion Guarantor or any other Person, or otherwise, all as though such amount had not been paid. The rights of the Beneficiaries created or granted herein and the enforceability of this Guarantee with respect to Completion Guarantor at all times shall remain effective to guarantee the full amount of all the Guaranteed Obligations even though the Secured Obligations of certain (but not all) of the Beneficiaries shall have been paid in full and even though the respective Secured Obligations of the Beneficiaries, or any part thereof, or any security or guarantee therefor, may be or hereafter may become invalid or otherwise unenforceable as against the Company or any other Related Party or any other guarantor or surety and whether or not the Company or any other Related Party shall have any personal liability with respect thereto. Completion Guarantor expressly waives any and all defenses now or hereafter arising or asserted by reason of (a) any disability or other defense of the Company or any other Related Party with respect to any of the Secured Obligations, (b) the unenforceability or invalidity of any security or guarantee for any of the Secured Obligations or the lack of perfection or continuing perfection or failure of priority of any security for any of the Secured Obligations, (c) the cessation for any cause whatsoever of the liability of the Company or any other Related Party (other than by reason of the full payment and performance of all their respective Secured Obligations and the termination of all commitments under the pertinent transaction documents), (d) any failure of the Beneficiaries to marshal assets in favor of the Company, any other Related Party or any other Person, (e) any failure of the Beneficiaries to give notice of sale or other disposition of any collateral securing any Secured Obligation to Completion Guarantor or any other Person or any defect in any notice that may be given in connection with any sale or disposition of any collateral securing any Secured Obligation, (f) any failure of the Beneficiaries to comply with applicable Laws in connection with the sale or other disposition of any collateral securing any Secured Obligation or other security for any Secured Obligation, including without limitation, any failure of the Beneficiaries to conduct a commercially reasonable sale or other disposition of any collateral securing any Secured Obligation or other security for any Secured Obligation, (g) any

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

act or omission of the Beneficiaries or others that directly or indirectly results in or aids the discharge or release of the Company or any other Related Party or any of their respective Secured Obligations or any security or guarantee therefor by operation of law or otherwise, (h) any Law which provides that the obligation of a surety or guarantor must neither be larger in amount nor in other respects more burdensome than that of the principal or which reduces a surety’s or guarantor’s obligation in proportion to the principal obligation, (i) any failure of the Beneficiaries to file or enforce a claim in any bankruptcy or other proceeding with respect to any Person, (j) the election by the Beneficiaries, in any bankruptcy proceeding of any Person, of the application or non-application of Section 1111(b)(2) of the United States Bankruptcy Code, (k) any extension of credit or the grant of any Lien under Section 364 of the Bankruptcy Code of the United States, (l) any use of cash collateral under Section 363 of the Bankruptcy Code of the United States, (m) any agreement or stipulation with respect to the provision of adequate protection in any bankruptcy proceeding of any Person, (n) the avoidance of any Lien in favor of the Beneficiaries for any reason, (o) any bankruptcy, insolvency, reorganization, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against any Person, including any discharge of, or bar or stay against collecting, all or any of the Secured Obligations (or any interest thereon) in or as a result of any such proceeding, (p) to the extent permitted in paragraph 40.495 of the Nevada Revised Statutes (“NRS”), the benefits of the one-action rule under NRS Section 40.430, or (q) any action taken by the Enforcement Collateral Agent that is authorized by this Section or any other provision of any transaction document. Without limiting the generality of any of the foregoing, in the event of any dissolution or insolvency of Completion Guarantor, the general inability of Completion Guarantor to pay debts as they mature, an assignment by Completion Guarantor for the benefit of creditors, the institution of any proceeding by or against Completion Guarantor alleging Completion Guarantor is insolvent or unable to pay its debts as they mature, and such event occurs prior to the Completion Date, the Beneficiaries shall be deemed to have an accelerated obligation under this Guarantee in the amount of Completion Guarantor’s estimated liability under this Guarantee (which in no circumstances shall be less than (a) $300,000,000 prior to the Perini Lawsuit Resolution and (b) $50,000,000 subsequent to the Perini Lawsuit Resolution), and the Enforcement Collateral Agent shall be entitled to file a proof of claim and otherwise pursue the allowance and recovery of such a claim (and take any and all other actions in connection therewith) in any such proceeding.

Completion Guarantor represents and warrants to the Beneficiaries that Completion Guarantor has established adequate means of obtaining from the Company and each other Related Party, on a continuing basis, financial and other information pertaining to the businesses, operations and condition (financial and otherwise) of the Company and each other Related Party and their properties, and Completion Guarantor now is and hereafter will be completely familiar with the businesses, operations and condition (financial and otherwise) of the Company and each other Related Party and their properties. Completion Guarantor hereby expressly waives and relinquishes any duty

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

on the part of the Beneficiaries (should any such duty exist) to disclose to Completion Guarantor any matter, fact or thing related to the businesses, operations or condition (financial or otherwise) of the Company or each other Related Party or their properties, whether now known or hereafter known by the Beneficiaries during the life of this Guarantee.

11. Liens on Real Property. Completion Guarantor expressly waives any defenses to the enforcement of this Guarantee or any rights of the Beneficiaries created or granted hereby or to the recovery by the Beneficiaries against the Company, any other Related Party or any other Person liable therefor of any deficiency after a judicial or nonjudicial foreclosure or sale because all or any part of the Guaranteed Obligations or the Secured Obligations are secured by real property. This means, among other things: (1) the Beneficiaries may collect from Completion Guarantor without first foreclosing on any real or personal property collateral pledged by the Related Parties or by Completion Guarantor; (2) if the Beneficiaries foreclose on any real property collateral pledged by the Related Parties or by Completion Guarantor: (A) the amount of the Secured Obligations may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price; and (B) the Beneficiaries may collect from Completion Guarantor even if the Beneficiaries, by foreclosing on the real property collateral, have destroyed, terminated, or otherwise adversely affected any right Completion Guarantor may have to collect from the Related Parties. This is an unconditional and irrevocable waiver of any rights and defenses Completion Guarantor may have because all or any part of the Guaranteed Obligations or the Secured Obligations are secured by real property. Completion Guarantor expressly waives any defenses or benefits that may be derived from NRS Section 40.430 and judicial decisions relating thereto, and NRS Sections 40.451, 40.455, 40.457 and 40.459, and all other suretyship defenses it otherwise might or would have under Nevada Law or other applicable Law. Completion Guarantor expressly waives any right to receive notice of any judicial or nonjudicial foreclosure or sale of any real property or interest therein subject to any such deeds of trust or mortgages or other instruments and Completion Guarantor’s or any other Person’s failure to receive any such notice shall not impair or affect Completion Guarantor’s obligations hereunder or the enforceability of this Guarantee or any rights of the Beneficiaries created or granted herein.

12. Subrogation, Indemnification and Contribution. Other than in respect of MGM Completion Guarantee Reimbursement Amount and the application of Condo Proceeds (which shall be payable to Completion Guarantor as contemplated by Section 2.3 hereof), Completion Guarantor hereby defers and subordinates, until all of the Secured Obligations have been indefeasibly paid and performed in full and any commitments with respect to the Secured Obligations are terminated, (i) all rights to indemnification by the Related Parties in respect of any payments made by Completion Guarantor hereunder, (ii) all subrogation rights arising out of the making of such payments, and all other similar rights which may arise in favor of Completion Guarantor against any Related Party, (iii) all rights to set off against the assets of any Related Party, and (iv) all rights to reimbursement, to exoneration or to any other rights that could accrue to a surety against a principal, to a guarantor against a maker or obligor, to an accommodation party against the party accommodated, or to a holder or transferee against a maker, and which Completion Guarantor may have or hereafter acquire against any Related Party in connection with or as a result of Completion Guarantor’s execution, delivery and performance of this Guarantee.

Completion Guarantor warrants and agrees that each of the waivers and consents set forth herein are made with full knowledge of their significance and consequences, with the understanding that events giving rise to any defense or right waived may diminish, destroy or otherwise adversely affect rights which Completion Guarantor otherwise may have against the Company, any other Related Party, any Beneficiary or others, or against any collateral securing any Secured Obligation, and that, under the circumstances, the waivers and consents herein given are reasonable and not contrary to public policy or Law. Completion Guarantor acknowledges that it has either consulted with legal counsel regarding the effect of this Guarantee and the waivers and consents set forth herein, or has made an informed decision not to do so.

14.2 The execution, delivery and performance of this Guarantee does not (i) violate any provisions of law or any order or any court or other agency of government, (ii) contravene any provision of any material contract or agreement to which Completion Guarantor is a party or by which Completion Guarantor or Completion Guarantor’s assets are bound, or (iii) result in the creation or imposition of any lien, charge or encumbrance of any nature upon an property, asset or revenue of Completion Guarantor except pursuant to or as set forth in the Circus Deeds of Trust.

14.3 All consents, approvals, orders and authorizations of, and registrations, declarations and filings with, any governmental agency or authority or other person or entity, if any, which are required to be obtained in connection with the execution and delivery of this Guarantee or the performance of Completion Guarantor’s obligations hereunder have been obtained, and each is in full force and effect.

hereunder to any other person without the written consent of each Collateral Agent, except that Completion Guarantor may delegate its obligation to fund Completion Costs hereunder to any of its wholly-owned direct or indirect Subsidiaries so long as such Subsidiary is a party to the Sponsor Subordination Agreement; provided, however, under no circumstances shall such delegation relieve Completion Guarantor of its obligations under this Guarantee.

16. Additional Waiver. No delay on the part of any Beneficiary in exercising any of its rights (including those hereunder) and no partial or single exercise thereof and no action or non-action by any Beneficiary, with or without notice to Completion Guarantor or anyone else, shall constitute a waiver of any rights or shall affect or impair this Guarantee.

17. Interpretation. The section headings in this Guarantee are for the convenience of reference only and shall not affect the meaning or construction of any provision hereof.

19. Costs and Expenses. Completion Guarantor agrees to pay to each Collateral Agent all costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) incurred by such Collateral Agent in the enforcement or attempted enforcement of this Guarantee, whether or not an action is filed in connection therewith, and in connection with any waiver or amendment of any term or provision hereof. All advances, charges, costs and expenses, including, without limitation, reasonable attorneys’ fees and disbursements (including the reasonably allocated cost of legal counsel employed by such Collateral Agent), incurred or paid by such Collateral Agent in exercising any right, privilege, power or remedy conferred by this Guarantee, or in the enforcement or attempted enforcement thereof, shall be subject hereto and shall become a part of the Guaranteed Obligations (and shall not be subject to any liability cap) and shall be paid to such Collateral Agent by Completion Guarantor, immediately upon demand, together with interest thereon at the Default Rate provided for under the applicable transaction document, which in the case of the Credit Agreement Collateral Agent, shall be the Amended and Restated Credit Agreement.

20. Construction of this Guarantee. This Guarantee is intended to give rise to absolute and unconditional obligations on the part of Completion Guarantor; hence, in any

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

construction hereof, notwithstanding any provision of any transaction document to the contrary, this Guarantee shall be construed strictly in favor of the Beneficiaries (and against Completion Guarantor) in order to accomplish its stated purpose.

21. Liability. Completion Guarantor and by its acceptance hereof the Beneficiaries hereby confirm that it is the intention of all such parties that the guarantees by Completion Guarantor pursuant to this Guarantee do not constitute a fraudulent transfer or conveyance for purposes of any federal or state Law. To effectuate the foregoing intention, and notwithstanding any other provision of this Guarantee to the contrary, in the event that any action or proceeding is brought in whatever form and in whatever forum seeking to invalidate Completion Guarantor’s obligations under this Guarantee under any fraudulent conveyance, fraudulent transfer theory, or any other theory under any law, including whether under state or federal law, Completion Guarantor, automatically and without any further action being required of such Completion Guarantor or any Collateral Agent, shall be liable under this Guarantee only for an amount equal to the maximum amount of liability that could have been incurred under applicable law by the Completion Guarantor under any guarantee of the Guaranteed Obligations (or any portion thereof) at the time of the execution and delivery of the Original Guarantee as such term is defined herein (or, if such date is determined not to be the appropriate date for determining the enforceability of such Completion Guarantor’s obligations hereunder for fraudulent conveyance or transfer (or similar avoidance) purposes, on the date determined to be so appropriate) without rendering such a hypothetical Guarantee voidable under applicable law relating to fraudulent conveyance, fraudulent transfer, or any other grounds for avoidance (such highest amount determined hereunder being any such Completion Guarantor’s “Maximum Completion Guarantee Amount”), and not for any greater amount, as if the stated amount of this Guarantee as to such Completion Guarantor had instead been the Maximum Completion Guarantee Amount. This Section is intended solely to preserve the rights of each Collateral Agent and other Beneficiaries under this Guarantee to the maximum extent not subject to avoidance under applicable law, and neither any Completion Guarantor nor any other person or entity shall have any right or claim under this Section with respect to the limitation described in this Guarantee, except to the extent necessary so that the obligations of any Completion Guarantor under this Guarantee shall not be rendered voidable to the detriment of the Beneficiaries under applicable law. The liability of Completion Guarantor hereunder is independent of any other guarantees at any time in effect with respect to all or any part of the Guaranteed Obligations, including the Dubai World Completion Guarantee, and Completion Guarantor’s liability hereunder may be enforced regardless of the existence of any such guarantees. Any termination by or release of Completion Guarantor in whole or in part shall not affect the continuing liability of any other guarantor, and no notice of any such termination or release shall be required. The execution hereof by Completion Guarantor is not founded upon an expectation or understanding that any other guarantee of the Guaranteed Obligations will ultimately be enforceable.

22. Amendments. This Guarantee may be amended only with the written consent of Completion Guarantor, the Company and each Collateral Agent.

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

23. Counterparts. This Guarantee may be executed in one or more duplicate counterparts, and when executed and delivered by all of the parties listed below shall constitute a single binding agreement.

24. Enforcement. At any time that Completion Guarantor fails to fund, on a timely basis, the amount of any Guaranteed Obligation after receipt of a proper demand hereunder, the Enforcement Collateral Agent shall be entitled to seek remedies against Completion Guarantor to compel the funding of its obligations hereunder. The Enforcement Collateral Agent may exercise any remedy available at law or equity to enforce this Guarantee, including, without limitation, the following:

(a) Specific Performance. The Enforcement Collateral Agent may seek an order for specific performance of Completion Guarantor’s funding obligations. Completion Guarantor agrees that money damages would be an inadequate remedy for breach of its funding obligations hereunder and hereby agrees in advance to an order of specific performance enforcing any or all of such obligations; and

(b) Foreclosure. The Enforcement Collateral Agent may proceed to foreclose against the Collateral pursuant to the Circus Deeds of Trust. The proceeds of any Collateral secured by the Circus Deeds of Trust shall be deemed to be applied in the order of priority set forth in Section 4.1 hereof.

25. Enforcement Collateral Agent. Completion Guarantor acknowledges that each Collateral Agent, insofar as Completion Guarantor is concerned, is authorized to enforce the provisions of this Guarantee for the benefit of the Beneficiaries. Each party hereto (including Completion Guarantor) further acknowledges that whichever Collateral Agent is the then-Applicable Collateral Agent (as such term is defined in the First Lien Intercreditor Agreement) (the “Enforcement Collateral Agent”) shall be the exclusive agent of the Beneficiaries to exercise or enforce their rights, remedies, privileges and powers under this Guarantee and to otherwise act on their behalf in all matters related hereto. Completion Guarantor shall respect and treat any and all actions so taken by the Enforcement Collateral Agent as if taken by the Beneficiaries. So long as the Intercreditor Agreements remain in force pursuant to their terms, (a) any action taken or not taken by the Credit Agreement Collateral Agent or the Enforcement Collateral Agent (as the case may be) pursuant to the provisions hereof shall be deemed to be an action taken or not taken (as the case may be) by a Collateral Agent pursuant to the provisions of the Intercreditor Agreements, (b) without limiting the generality of the foregoing, in taking or not taking any such action, Credit Agreement Collateral Agent or the Enforcement Collateral Agent (as the case may be) shall have the full benefit of all exculpatory provisions in the Intercreditor Agreements, and (c) except for those specific instances when the Credit Agreement Collateral Agent (in such capacity) is expressly authorized to act (or not act) pursuant to the provisions of this Guarantee, only the Enforcement Collateral Agent may take any action, on behalf of the Beneficiaries, to enforce this Guarantee against Completion Guarantor.

26. Not a Contract to Make a Loan, Etc. This Guarantee shall not be deemed to be a contract to make a loan, or extend other debt financing or financial accommodation, for the

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

benefit of the Company or to issue a security of the Company within the meaning of Section 365(c)(2), (e)(2)(B) of the United States Bankruptcy Code.

27. Governing Law; Jurisdiction; Etc.

27.1 GOVERNING LAW. THIS GUARANTEE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEVADA.

27.2 SUBMISSION TO JURISDICTION. EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEVADA SITTING IN ▇▇▇▇▇ COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE DISTRICT OF NEVADA, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTEE, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEVADA STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS GUARANTEE SHALL AFFECT ANY RIGHT THAT ANY COLLATERAL AGENT OR ANY BENEFICIARY MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS GUARANTEE AGAINST COMPLETION GUARANTOR OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

27.3 WAIVER OF VENUE. EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN SECTION 27.2 OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMUTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

27.4 SERVICE OF PROCESS. EACH OF THE PARTIES HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 18. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

28. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH OF THE PARTIES HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

29. Integration of Terms. This Guarantee contains the entire agreement between Completion Guarantor and the Beneficiaries relating to the subject matter hereof and supersedes all oral statements and prior writings with respect hereto.

30. No Defense. Completion Guarantor expressly agrees that its continuing, several liability for the Guaranteed Obligations shall not be affected or diminished in any way by any defense, including, without limitation, any sovereign immunity defense, Dubai World may possess or assert with respect to Dubai World’s obligations under the Dubai World Completion Guarantee. The execution hereof by Completion Guarantor is not founded upon an expectation or understanding that Dubai World will not possess or assert any sovereign immunity defense or any other defense with respect to payment under the Dubai World Completion Guarantee. It is understood and agreed that nothing in this Section shall diminish or otherwise detract from Completion Guarantor’s waivers of defenses set forth in this Guarantee.

31. Satisfaction. Subject in all respects to automatic reinstatement pursuant to the provisions of Section 9, this Guarantee shall be deemed satisfied (and thus, of no further force and effect) upon the final resolution, whether via adjudication pursuant to a final and nonappealable order or judgment of a court of competent jurisdiction, payment, or settlement, of all Completion Costs (and attendant amounts, if any, owing under Section 19); provided, however, that such satisfaction shall have no effect on (and specifically, shall not in any manner whatsoever vitiate, affect the validity or finality, un-do, or otherwise disturb) any Completion Cost previously paid or otherwise resolved, whether pursuant to the provisions of this Guarantee or otherwise.

32. Severability. Consistent with the provisions of Section 21 hereof, wherever possible, each provision of this Guarantee will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Guarantee is prohibited by or invalid under such law, such provision will be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Guarantee.

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

33. Conflicts Among Documents. Any conflict between the provisions of this Guarantee and the provisions of any agreement or other instrument relating to any of the Secured Obligations shall be governed by the provisions of this Guarantee.

34. Nature of Secured Obligations Inter Se. Completion Guarantor acknowledges that the purpose of this Guarantee is to provide for the resolution of Completion Costs so that mechanics liens and other covered claims on CityCenter that might otherwise constitute competing (and/or senior) lien claims in and to CityCenter to the possible detriment of the Beneficiaries (regardless of the relative priority of the liens or other rights of the Beneficiaries inter se) are (and can be) discharged. As such, Completion Guarantor further acknowledges that nothing contained herein is intended to contradict or be deemed to be evidence of an intent to otherwise vary the meaning of the provisions of the Intercreditor Agreements, including as to the nature, priority, or potential classification of the Secured Obligations inter se, including the provisions of the General Intercreditor Agreement to the effect that (i) the Junior Lien Secured Parties’ claims against the Company and/or any other Grantor (as such term is defined in the General Intercreditor Agreement), including in respect of the Common Collateral (as such term is defined in the General Intercreditor Agreement), constitute claims separate and apart (and of a different nature) from each of the Credit Agreement Obligations and the Additional First Lien Obligations against the Company and each other Grantor (as such term is defined in the General Intercreditor Agreement), including in respect of the Common Collateral, (ii) the grant of Liens (as such term is defined in the General Intercreditor Agreement) to secure either the Credit Agreement Obligations or the Additional Lien Obligations each constitutes a separate and distinct grant of Liens from any Liens granted to secure the Junior Lien Obligations; and (iii) because of, among other things, their differing payment terms, their differing covenant rights, and their differing rights in the Common Collateral (including vis a vis any Grantor and/or in directing the exercise of any rights in and remedies against the Common Collateral), each of the Credit Agreement Obligations and the Additional First Lien Obligations is fundamentally different from each other and moreover, each is fundamentally different and distinct from (and substantially dissimilar, within the meaning of Section 1122 of the Bankruptcy Code, to) the Junior Lien Obligations and must be separately classified in any Plan of Reorganization (as such term is defined in the General Intercreditor Agreement) proposed or confirmed in an Insolvency or Liquidation Proceeding (as such term is defined in the General Intercreditor Agreement).

35. Amendment, Restatement, and Continuation of Original Guarantee. This Guarantee shall not replace the Existing Completion Guarantee and shall not otherwise become effective unless and until the occurrence of the Effective Date. Completion Guarantor irrevocably acknowledges and confirms: (a) that, upon such effectiveness, this Guarantee shall constitute an amendment, restatement, and uninterrupted continuation of the Original Guarantee (it being agreed that the remaining claims under the Original Guarantee are limited to the Completion Costs and to the other Guaranteed Obligations under Section 19 relating thereto), (b) that the Completion Guarantor’s obligations hereunder were first incurred to the extent set forth therein upon the initial execution and delivery of the Original Guarantee and expanded, if at all, to the extent set forth in the Existing Completion Guarantee, (c) that nothing contained in the Amended and Restated Credit Agreement, the Additional First Lien Agreement, the Junior Lien Indenture, the First Lien Intercreditor Agreement, the General Intercreditor Agreement, or in any other loan document involving the Company impairs or otherwise adversely affects or shall be

Second Amended and Restated Sponsor
Completion Guarantee (MGM Resorts International)

deemed to have impaired or to have otherwise adversely affected any of the Completion Guarantor’s obligations under the Original Guarantee and Existing Completion Guarantee as amended and restated first in the Existing Completion Guarantee and now herein, (d) that such Original Guarantee, as amended and restated first in the Existing Completion Guarantee and now herein, otherwise remains in full force and effect, (e) that the Completion Guarantor hereby reaffirms and ratifies the Original Guarantee, as amended and restated first in the Existing Completion Guarantee and as now limited herein, in each and every respect, and (f) that this Guarantee constitutes its valid and binding obligations.
