Item 1.01 Entry into a Material Definitive Agreement.

Indenture

In connection with the consummation of the previously announced acquisition by Wolverine World Wide, Inc. (the “Company”) of the Performance + Lifestyle Group business (the “PLG Business”) of Collective Brands, Inc., a Delaware corporation (“CBI”), the Company, certain domestic subsidiaries of the Company named therein (the “Guarantors”), and Wells Fargo Bank, National Association, as trustee (the “Trustee”), entered into the Senior Notes Indenture dated as of October 9, 2012 (the “Indenture”), pursuant to which the Company issued $375 million aggregate principal amount of 6.125% Senior Notes due 2020 (the “Notes,” and the offering thereof, the “144A Offering”).

The Notes will bear interest at the rate of 6.125% per year. Interest on the Notes is payable on April 15 and October 15 of each year, beginning on April 15, 2013. The Notes will mature on October 15, 2020. At any time prior to October 15, 2016, the Company may redeem the Notes, in whole or in part, at a redemption price equal to 100% of the aggregate principal amount of the Notes, plus a “make-whole” premium as set forth in Indenture, plus accrued and unpaid interest. In addition, before October 15, 2015, the Company may redeem up to 35% of the Notes at a redemption price equal to 106.125% of their principal amount, plus accrued and unpaid interest, using the proceeds of certain equity offerings. Further, on and after October 15, 2016, the Company may redeem the Notes, in whole or in part, at a redemption price equal to 103.063% of the principal amount, if redeemed during the twelve-month period beginning on October 15, 2016, 101.531% of the principal amount, if redeemed during the twelve-month period beginning on October 15, 2017 and 100.000% of the principal amount, if redeemed during the twelve-month period beginning on October 15, 2018 and thereafter, in each case plus accrued and unpaid interest.

The Indenture requires that, upon the occurrence of a Change of Control (as defined in the Indenture), unless the Company has exercised its right to redeem all of the Notes pursuant to the Indenture, the Company shall offer to purchase all of the Notes at a purchase price in cash equal to 101% of the outstanding principal amount of such Notes, plus accrued and unpaid interest. If the Company or its restricted subsidiaries dispose of assets, under certain circumstances, the Company will be required to use the net proceeds from such disposals to make an offer to purchase Notes at an offer price in cash in an amount equal to 100% of the outstanding principal amount of such Notes, plus accrued and unpaid interest.

The proceeds from the 144A Offering will be used to finance, in part, the acquisition of the PLG Business, repay any amounts outstanding under the Company’s existing revolving credit facility, repay certain of CBI’s indebtedness, and pay related fees and expenses.

The Indenture contains covenants that, among other things, restrict the ability of the Company and its restricted subsidiaries to incur additional indebtedness and guarantee indebtedness; pay dividends or make other distributions in respect of, or repurchase or redeem, the Company’s capital stock; prepay, redeem or repurchase certain debt; issue certain preferred stock or similar equity securities; make loans and investments; sell or otherwise dispose of assets; consolidate or

2

merge; incur liens; enter into transactions with affiliates; and enter into agreements restricting the ability of the Company’s restricted subsidiaries to pay dividends and make other distributions. Certain of the covenants will be suspended upon the Notes achieving an investment grade rating from specified rating agencies. The terms of the Indenture include customary events of default, including, but not limited to, failure to make payment, failure to comply with the obligations set forth in the Indenture, certain defaults on certain other indebtedness, and invalidity of the guarantees under the notes issued pursuant to the Indenture.

The Notes are guaranteed on a senior unsecured basis, by each of the Company’s existing and future domestic subsidiaries that is a borrower under or that guarantees obligations under the Company’s Credit Agreement dated July 31, 2012 (as amended, the “New Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and as a lender, J.P. Morgan Europe Limited, as foreign currency agent, Wells Fargo Bank, National Association, as syndication agent and as a lender, Fifth Third Bank, as documentation agent and as a lender, PNC Bank, National Association, as documentation agent and as a lender and the other lenders party thereto, or that guarantees the Company’s other indebtedness or indebtedness of any Guarantor, which indebtedness in either case is in an aggregate principal amount of $50.0 million or greater. The Notes and the related guarantees are the Company’s and the Guarantors’ senior unsecured obligations, and will rank senior in right of payment to all of the Company’s and the Guarantors’ existing and future subordinated indebtedness; rank equally in right of payment with all of the Company’s and the Guarantors’ existing and future senior indebtedness; be effectively subordinated to any of the Company’s and the Guarantors’ existing and future secured debt, including indebtedness under the New Credit Agreement, to the extent of the value of the assets securing such debt; and be structurally subordinated to all of the existing and future liabilities (including debt and trade payables but excluding intercompany liabilities) of each of the Company’s subsidiaries that do not guarantee the Notes. The Notes are not registered under the Securities Act of 1933, as amended (the “Securities Act”), and the Notes are subject to restrictions on transferability and resale.

The Indenture is filed as Exhibit 4.1 to this Current Report on Form 8-K and the description of the material terms of the Indenture is qualified in its entirety by reference to such exhibit, which is incorporated herein by reference.

Registration Rights Agreement

In connection with the sale of the Notes, the Company, the Guarantors and J.P. Morgan Securities LLC, as representative of the several initial purchasers, entered into a registration rights agreement, dated as of October 9, 2012 (the “Registration Rights Agreement”). Under the Registration Rights Agreement, the Company and the Guarantors are obligated to file for the benefit of the holders of the Notes an exchange offer registration statement to allow holders to exchange Notes for the same principal amount of a new issue of notes with substantially identical terms, except that the new issue of notes will generally be freely transferable without further registration under the Securities Act. In addition, the Company and the Guarantors, under certain circumstances, must use their reasonable best efforts to file and cause to become effective a shelf registration statement to cover resales of the Notes.

3

If (i) the Company and the Guarantors fail to complete the registered exchange offer or a shelf registration statement is required and has not been declared effective within 360 days after the initial issuance of the Notes, (ii) an initial purchaser requests a shelf registration statement and such shelf registration statement does not become effective by the later of 360 days after the initial issuance of the Notes or the 90^th day following such request, or (iii) a shelf registration is declared effective but thereafter, during any 12-month period, ceases for more than 30 days to be effective or usable in connection with resales or exchanges of Notes during the time periods specified in the Registration Rights Agreement or ceases to be effective on more than two occasions, the Company will be required to pay additional interest on the Notes. With respect to the first 90-day period immediately following the occurrence of the first registration default, additional interest shall be payable in an amount equal to 0.25% per annum on the principal amount of Notes. The amount of the additional interest will increase by an additional 0.25% per annum on the principal amount of Notes with respect to each subsequent 90-day period until all registration defaults have been cured, provided that the maximum rate at which such additional interest accrues may not exceed 1.00% per annum.

The Registration Rights Agreement is filed as Exhibit 4.3 to this Current Report on Form 8-K and the description of the material terms of the Registration Rights Agreement is qualified in its entirety by reference to such exhibit, which is incorporated herein by reference.

Second Amendment to the New Credit Agreement

On October 8, 2012, the Company entered into the Second Amendment (the “Second Amendment”) to the New Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent and as a lender, J.P. Morgan Europe Limited, as foreign currency agent, Wells Fargo Bank, National Association, as syndication agent and as a lender, Fifth Third Bank, as documentation agent and as a lender, PNC Bank, National Association, as documentation agent and as a lender and the other lenders party thereto. A summary of the terms of the New Credit Agreement may be found in the Company’s Current Report on Form 8-K filed on August 1, 2012, and a summary of the terms of the First Amendment to the New Credit Agreement may be found in the Company’s Current Report on Form 8-K filed on October 4, 2012, which summaries are incorporated herein by reference.

The Second Amendment reduces the interest rate margin applicable to the term loan B facility (the “Term Loan B Facility”) under the New Credit Agreement. Under the Second Amendment, the initial interest rate per annum applicable to amounts outstanding under the Term Loan B Facility will be, at the Company’s option, either (i) the ABR as defined in the New Credit Agreement (the “Base Rate”) plus an applicable margin of 2.00% per annum, or (ii) the Eurocurrency Rate as defined in the New Credit Agreement (the “Eurocurrency Rate”) plus an applicable margin of 3.00% per annum. In addition, under the Second Amendment, the applicable margin for both Base Rate and Eurocurrency Rate loans under the Term Loan B Facility is fixed at the levels set forth above, rather than being subject to adjustment based on the pricing grid set forth in the original New Credit Agreement. The applicable margins for the term loan A facility and the revolving facility under the New Credit Agreement remain unchanged by the Second Amendment.
