On June 12, 2013, Marriott Vacations Worldwide Corporation (the “Company”) and its subsidiary Marriott Ownership Resorts, Inc. (the “Borrower”) entered into a First Amendment (the “Credit Agreement Amendment”) to the Amended and Restated Credit Agreement, dated as of November 30, 2012 (the “Credit Agreement”), among the Company, the Borrower, the several banks and other financial institutions or entities from time to time party thereto (the “Lenders”), Bank of America, N.A. and Deutsche Bank Securities Inc., as co-documentation agents, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Deutsche Bank Securities Inc., as co-syndication agents, and JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”).

Pursuant to the Credit Agreement, the maximum ratio of consolidated total debt to consolidated adjusted EBITDA (as defined in the Credit Agreement) that the Company is required to maintain will be 6 to 1 through the end of the first quarter of 2013, then will decrease to 5.75 to 1 through the end of the first quarter of 2014, and to 5.25 to 1 thereafter. Prior to the Credit Agreement Amendment, the ratio the Company was required to maintain was 6 to 1 through the end of the first quarter of 2013, then 5.25 to 1 through the end of the 2014 fiscal year, and 4.75 to 1 thereafter. In addition, the Credit Agreement Amendment provides for certain amendments to the definitions of “Consolidated Adjusted EBITDA” and “Consolidated Total Debt” that will provide the Company with additional flexibility.

In addition to the amendments described above, the Credit Agreement Amendment also includes modifications intended to comply with certain provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act regarding the guarantee of foreign exchange and interest rate swap transactions by certain of those subsidiaries of the Company that guarantee the obligations of the Borrower under the Credit Agreement (the “Guarantors”). On June 12, 2013, the Company, the Borrower and the Guarantors also entered into a First Amendment to the Amended and Restated Guarantee and Collateral Agreement dated as of November 30, 2012 (the “Guarantee and Collateral Agreement”) in favor of the Administrative Agent, which provides for changes for the same purpose to the Guarantee and Collateral Agreement.

From time to time, the Administrative Agent and the other financial institutions party to the Credit Agreement or their affiliates may have performed, and may in the future perform, various commercial banking, investment banking and other financial advisory services for the Company and its affiliates for which they have or will receive customary fees and expenses. In particular, some of these financial institutions or their affiliates participate in the Company’s vacation ownership notes receivable warehouse facility and may also have participated in transactions involving the securitization of vacation ownership notes receivable undertaken by the Company’s subsidiaries.

The description of each of the agreements above is qualified in its entirety by reference to the full text of the agreements, which are filed as exhibits to this Current Report on Form 8-K and are hereby incorporated by reference.

At a meeting of the Board of Directors (the “Board”) of the Company held on June 7, 2013, upon recommendation of the Compensation Policy Committee (the “Compensation Policy Committee”) of the Board, the Board adopted the Marriott Vacations Worldwide Corporation Deferred Compensation Plan (the “Plan”). The Plan will be effective as of July 1, 2013. The Plan will be an unfunded plan maintained primarily for the purpose of providing deferred compensation for a select group of management or highly-compensated employees, as described in Sections 201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), as well as non-employee directors of the Company. The Plan will not be subject to most of the provisions of ERISA. The Plan is intended to satisfy the applicable requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”).

Although the Plan will not initially be funded, upon a change in control (as defined in the Plan) of the Company, the Company or any successor entity will deposit a sum equal to the amounts deferred under the Plan into a trust fund; provided that such trust will not be funded if the funding would result in taxable income to a

participant by reason of Section 409A(b) of the Code. In addition, at such other time as determined by the Board, payments due to be made under the Plan may be paid out of assets transferred by the Company to a trust fund maintained pursuant to the terms and conditions of a trust agreement.

Under the terms of the Plan, each Plan participant may elect to defer receipt of up to 80% of his or her base salary, bonuses and/or commissions and all or part of any non-employee director fees until such future date as he or she elects in accordance with the terms of the Plan. The Company may credit participants’ accounts with additional amounts, referred to as employer credits, in an amount equal to any matching contributions that the participant did not receive for a year under the Marriott Vacations Worldwide Corporation 401(k) Retirement Savings Plan, or any successor plan thereto, due to the participant’s election to defer amounts under the Plan. In addition, the Company may, in its sole discretion, credit participants’ accounts with additional employer credits which will vest at a rate of 25% per year on the first four anniversaries of the date the discretionary employer credit was allocated to the participant’s account, provided that the participant remains in continued service with the Company. On a participant’s separation from service, unvested discretionary employer credits are generally forfeited. Upon a change in control of the Company or a participant’s death or retirement after reaching age 55 and completing ten continuous years of service, all employer credits will immediately vest in full.

A Plan participant may elect to receive his or her deferred amounts and vested employer credits in a lump sum or in installments over five, ten, fifteen or twenty years at either a separation from service or upon any of the first five anniversaries of a separation from service. Alternatively, a Plan participant may elect to receive his or her deferred amounts and vested employer credits in a lump sum in January of a specified year, so long as employer credits are deferred for at least four years and all other amounts are deferred for at least three years. Participants’ accounts will be credited with an investment return determined as if the account were invested in one or more investment funds made available by the administrator of the Plan (or which may be based on a fixed rate of interest selected by the administrator).

The administrator of the Plan may amend or terminate the Plan without the consent of the participants or their beneficiaries, but no amendment or termination may reduce any participant’s account balance based on deferrals already made, or divest any participant of rights to which he or she would have been entitled if the Plan had been terminated immediately prior to the effective date of such amendment.

The description of the Plan is qualified in its entirety by reference to the full text of the Plan, which is filed as an exhibit to this Current Report on Form 8-K and is hereby incorporated by reference.
