SECTION 2. GUARANTEE

        2.1. Guarantee.

        (a) Wynn Resorts hereby unconditionally and irrevocably, guarantees to the Administrative Agent, for the ratable benefit of the Secured Parties and their respective successors, indorsees, transferees and assigns, the prompt and complete payment and performance by the Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the Borrower Obligations.

        (b) The guarantee contained in this Section 2 shall remain in full force and effect until payment in full of all Borrower Obligations, notwithstanding that from time to time during the term of the Credit Agreement the Borrower may be free from any Borrower Obligations.

        (c) No payment made by the Borrower, Wynn Resorts, any Other Guarantor or any other Person or received or collected by any Secured Party from the Borrower, Wynn Resorts, any Other Guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Borrower Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of Wynn Resorts hereunder which shall, notwithstanding any such payment (other than any payment made by Wynn Resorts in respect of the Borrower Obligations or any payment received or collected from Wynn Resorts in respect of the Borrower Obligations), remain liable for the Borrower Obligations up to the maximum liability of Wynn Resorts hereunder until the Borrower Obligations are paid in full, no Letter of Credit shall be outstanding and the Commitments are terminated or have expired.

        2.2. Rights of Reimbursement, Contribution and Subrogation.

2

        (a) In case any payment is made on account of the Borrower Obligations by Wynn Resorts or is received or collected on account of the Obligations from Wynn Resorts or its property, Wynn Resorts may be entitled, subject to and upon payment in full of the Borrower Obligations, (A) to demand and enforce reimbursement for the full amount of such payment from the Borrower and (B) to demand and enforce contribution in respect of such payment from each Other Guarantor which has not paid its fair share of such payment, as necessary to ensure that (after giving effect to any enforcement of reimbursement rights provided hereby) Wynn Resorts and each Other Guarantor pays its fair share of the unreimbursed portion of such payment.

        (b) If and whenever (after payment in full of the Borrower Obligations) any right of reimbursement or contribution becomes enforceable by Wynn Resorts against any Other Guarantor as described in Section 2.2(a) or otherwise, Wynn Resorts may be entitled, subject to and upon payment in full of the Borrower Obligations, to be subrogated (equally and ratably with all Other Guarantors entitled to reimbursement or contribution from Wynn Resorts or any Other Guarantor as described in this Section 2.2) to any security interest that may then be held by the Administrative Agent upon any Collateral granted to it pursuant to the Security Documents. Such right of subrogation shall be enforceable solely against the Other Guarantors, and not against the Secured Parties, and neither the Administrative Agent nor any other Secured Party shall have any duty whatsoever to warrant, ensure or protect any such right of subrogation or to obtain, perfect, maintain, hold, enforce or retain any Collateral for any purpose related to any such right of subrogation. If subrogation is demanded by Wynn Resorts, then (after payment in full of the Borrower Obligations) the Administrative Agent shall deliver to Wynn Resorts, or to a representative of Wynn Resorts or of the guarantors of the Borrower Obligations generally, at the expense of Wynn Resorts, an instrument satisfactory to the Administrative Agent transferring, on a quitclaim basis without any recourse, representation, warranty or obligation whatsoever, whatever security interest the Administrative Agent then may hold in whatever Collateral may then exist that was not previously released or disposed of by the Administrative Agent.

        (c) All rights and claims arising under this Section 2.2 or based upon or relating to any other right of reimbursement, indemnification, contribution or subrogation that may at any time arise or exist in favor of Wynn Resorts as to any payment on account of the Borrower Obligations made by it or received or collected from its property shall be fully subordinated in all respects to the prior payment in full of all of the Borrower Obligations. Until payment in full of the Borrower Obligations, Wynn Resorts shall not demand or receive any collateral security, payment or distribution whatsoever (whether in cash, property or securities or otherwise) on account of any such right or claim. If any such payment or distribution is made or becomes available to Wynn Resorts in any bankruptcy case or receivership, insolvency or liquidation proceeding, such payment or distribution shall be delivered by the Person making such payment or distribution directly to the Administrative Agent, for application to the payment of the Borrower Obligations. If any such payment or distribution is received by Wynn Resorts, it shall be held by Wynn Resorts in trust, as trustee of an express trust for the benefit of the Secured Parties, and shall forthwith be transferred and delivered by Wynn Resorts to the Administrative Agent, in the exact form received and, if necessary, duly endorsed.

        (d) The obligations of Wynn Resorts under this Agreement, including its liability for the Borrower Obligations, are not contingent upon the validity, legality, enforceability, collectibility or sufficiency of any right of reimbursement, contribution or subrogation arising under this Section 2.2. The invalidity, insufficiency, unenforceability or uncollectibility of any such right shall not in any respect diminish, affect or impair any such obligation or any other claim, interest, right or remedy at any time held by any Secured Party against Wynn Resorts or its property. The Secured Parties make no representations or warranties in respect of any such right and shall have no duty to assure, protect, enforce or ensure any such right or otherwise relating to any such right.

        (e) Wynn Resorts reserves any and all other rights of reimbursement, contribution or subrogation at any time available to it as against any Other Guarantor, but (i) the exercise and enforcement of such

3

rights shall be subject to Section 2.2(d) and (ii) neither the Administrative Agent nor any other Secured Party shall ever have any duty or liability whatsoever in respect of any such right, except as provided in Section 2.2(c).

        (f) Wynn Resorts waives any right or claims of right to cause a marshalling of the Borrower's, Wynn Resorts' or any Other Guarantor's assets or to proceed against Wynn Resorts, the Borrower or any Other Guarantor in any particular order, including, but not limited to, any right arising out of Nevada Revised Statutes 40.430.

        2.3 Amendments, etc. with respect to the Borrower Obligations. Wynn Resorts shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Other Guarantor and without notice to or further assent by any such guarantor, any demand for payment of any of the Borrower Obligations made by any Secured Party may be rescinded by such Secured Party and any of the Borrower Obligations continued, and the Borrower Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, increased, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Secured Party, and the Credit Agreement and the other Loan Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the requisite Lenders under the Credit Agreement or all Lenders, as the case may be) may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by any Secured Party for the payment of the Borrower Obligations may be sold, exchanged, waived, surrendered or released. No Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Borrower Obligations or for the guarantee contained in this Section 2 or any property subject thereto.

        2.4 Guarantee Absolute and Unconditional. Wynn Resorts waives any and all notice of the creation, renewal, extension or accrual of any of the Borrower Obligations and notice of or proof of reliance by any Secured Party upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this Section 2; the Borrower Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all dealings between the Borrower and Wynn Resorts or any of the Other Guarantors, on the one hand, and the Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 2. Wynn Resorts waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Borrower, Wynn Resorts or any of the Other Guarantors. Wynn Resorts understands and agrees that the guarantee contained in this Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment and performance without regard to (a) the validity or enforceability of the Credit Agreement or any other Loan Document, any of the Borrower Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by any Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance hereunder) which may at any time be available to or be asserted by the Borrower or any other Person against any Secured Party, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Borrower or Wynn Resorts) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrower for the Borrower Obligations, or of Wynn Resorts under the guarantee contained in this Section 2, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against Wynn Resorts, any Secured Party may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against the Borrower, any Other Guarantor or any other Person or against any collateral security or guarantee for the Borrower Obligations or any right of offset with respect thereto, and any failure by any Secured Party to make any such demand, to pursue such other

4

rights or remedies or to collect any payments from the Borrower, any Other Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Borrower, any Other Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve Wynn Resorts of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any Secured Party against Wynn Resorts. For the purposes hereof "demand" shall include the commencement and continuance of any legal proceedings.

        2.5 Reinstatement. The guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Borrower Obligations is rescinded or must otherwise be restored or returned by any Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower, Wynn Resorts or any Other Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower, Wynn Resorts or any Other Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

        2.6 Payments. Wynn Resorts hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim in Dollars in immediately available funds at the office of the Administrative Agent located at the Payment Office specified in the Credit Agreement.

SECTION 3. SECURITY INTERESTS

        3.1. Restriction on Grant of Security Interest. Wynn Resorts hereby agrees that it shall not grant any security interests in any of its assets or properties (other than a security interest in favor of the Administrative Agent for the benefit of the Lenders and security interests granted in Excluded Assets or assets or properties that individually or in the aggregate have a fair market value of less than $10,000,000) in favor of any Person to secure (i) any Indebtedness of any of its Affiliates, (ii) any Guarantee Obligations by Wynn Resorts of Indebtedness of any of its Affiliates, or (iii) any Indebtedness incurred by Wynn Resorts (any such grant of security interest, a "Granted Security Interest"), unless:

        (a) Wynn Resorts concurrently executes and delivers to the Administrative Agent a security agreement in substantially the form of the security agreement related to the Granted Security Interest (a "Parent Security Agreement") and thereby grants a perfected, enforceable security interest in those assets or properties in favor of the Administrative Agent for the benefit of the Lenders to secure the obligations of Wynn Resorts pursuant to this Agreement; and

        (b) subject to the Intercreditor Agreements, the security interest described in clause (a) above ranks senior to or is pari passu with the Granted Security Interest.

        3.2. Further Assurances. Wynn Resorts shall execute and deliver such additional instruments, certificates or documents, and take all such actions as may be reasonably required from time to time in order to (a) carry out more effectively the purposes of this Agreement and the Parent Security Agreement (if any), (b) create, grant, perfect and maintain the validity, effectiveness, perfection and priority of the Parent Security Agreement (if any) and the Liens created, or intended to be created, thereby (if any), (c) ensure that this Agreement and the Liens created or purported to be created under the Parent Security Agreement (if any) have the ranking required under this Agreement; and (d) ensure that any of the rights granted or intended to be granted to the Administrative Agent under this Agreement or the Parent Security Agreement (if any) or under any other instrument executed in connection therewith or granted to Wynn Resorts thereunder or under any other instrument executed in connection therewith are protected and enforced. Upon the exercise by the Administrative Agent or any Secured Party of any power, right, privilege or remedy under this Agreement or the Parent Security Agreement which requires any consent, approval, recording, qualification or authorization of any governmental authority, Wynn Resorts shall execute and deliver all applications, certifications,

5

instruments and other documents and papers that may be required from Wynn Resorts for such governmental consent, approval, recording, qualification or authorization.

SECTION 4. SEPARATENESS

        Wynn Resorts hereby agrees that, for so long as there continues to be any outstanding Borrower Obligations, it shall comply with each of the following:

        (a) Wynn Resorts shall not conduct business in the name of any of the Loan Parties or the Completion Guarantor (collectively, the "Wynn Group Members"), nor shall it refer to any of the Wynn Group Members as a division, department or other subdivision of Wynn Resorts that is not recognized as a separate and distinct legal entity under applicable law. Wynn Resorts shall have separate stationery, invoices and checks in its own name and shall observe all organizational formalities. Wynn Resorts shall not refer to employees of a Wynn Group Member as employees of Wynn Resorts or of any Affiliate of Wynn Resorts that is not a Wynn Group Member. Wynn Resorts shall maintain arms'-length relationships with the Wynn Group Members, except for management fees, distributions and other specific transactions, to the extent expressly permitted by the Loan Documents. Wynn Resorts shall maintain adequate capital in light of its contemplated business purpose, transactions and liabilities. Wynn Resorts shall not commingle its funds with those of the Wynn Group Entities, and in all transactions involving the Wynn Group Entities and Wynn Resorts, the separate funds of each of the Wynn Group Members and Wynn Resorts shall be clearly traceable. The assets of Wynn Resorts shall remain identifiably separate from those of the Wynn Group Members such that there will be no material difficulty in segregating the assets of the Wynn Group Members from those of Wynn Resorts.

        (b) Wynn Resorts shall not hold out the Wynn Group Members to be other than legal entities separate and distinct from Wynn Resorts, and Wynn Resorts shall not hold out that the assets of the Wynn Group Members are available to satisfy the liabilities of Wynn Resorts. In any communications with creditors of Wynn Resorts that refer in any way directly or indirectly to the assets, liabilities, operations or results from operations of the Wynn Group Members, Wynn Resorts shall ensure that such communications accurately describe the separate existence of the Wynn Group Members and the fact that the assets of the Wynn Group Members are not available to satisfy the liabilities of Wynn Resorts.

        (c) Wynn Resorts shall maintain books, records and accounts separate and apart from each of the Wynn Group Members. In any consolidated financial statements of Wynn Resorts that refer to assets, liabilities, operations or results from operations of the Wynn Group Members, Wynn Resorts shall, in footnotes or otherwise, describe the assets, liabilities, operations and results from operations of the Wynn Group Members separately from those of Wynn Resorts and further shall note that (i) each Wynn Group Member is organized as a legal entity separate and distinct from Wynn Resorts, (ii) there is no agreement or other arrangement or relationship under which or pursuant to which the assets of a Wynn Group Member have been pledged or otherwise made available to satisfy the obligations of Wynn Resorts or any of its Affiliates that are not Wynn Group Members, and (iii) each Wynn Group Member has issued or guaranteed indebtedness that is secured by Liens on substantially all of the assets of said Wynn Group Member (except as otherwise permitted by the terms of the Loan Documents).

        (d) In addition to the foregoing, Wynn Resorts shall not take any other action that would reasonably be expected to call into question the separate identity of each Wynn Group Member from Wynn Resorts, or to create or increase any risk that the assets of any Wynn Group Member will be consolidated with those of Wynn Resorts or any other Person (other than another Wynn Group Member) under applicable federal or state bankruptcy or insolvency law.

SECTION 5. WYNN PUT AGREEMENT

        Wynn Resorts hereby agrees that it shall not amend, modify, waive or otherwise change, or consent or agree to any amendment, modification, waiver or other change to, or otherwise fail to enforce, or terminate or abandon, any of the provisions of the Wynn Put Agreement, if such amendment, modification, waiver or other change, failure to enforce, termination or abandonment (individually or collectively with all such amendments, modifications, waivers and other changes, failures to enforce, terminations or abandonments taken as a whole) would (a) have a material adverse affect on the ability of the Borrower or any other Loan Party to develop, construct or operate the Project, (b) cause the Completion Date to occur or result in that date occurring after the Scheduled Completion Deadline, (c) materially impair the rights or remedies of the Lenders, or (d) materially impair the development, use or operation of the Project.
