Item 1.01. Entry into a Material Definitive Agreement.

On March 7, 2012, G&K Services, Inc. (the “Company”) and G&K Services Canada Inc., an indirect wholly-owned subsidiary of the Company (“Canadian Borrower”), entered into, as borrowers, a $250,000,000 five year syndicated revolving credit facility (the “Credit Facility”) with the financial institutions and other lenders named therein, JPMorgan Chase Bank, N.A. as administrative agent (“JPMorgan”), Wells Fargo Bank, National Association and Bank of America, N.A., as co-syndication agents and SunTrust Bank and U.S. Bank National Association, as co-documentation agents.

This Credit Facility replaces that certain Credit Agreement, dated as of July 1, 2009, among the Company, the Canadian Borrower, the financial institutions from time to time parties thereto as lenders, and JPMorgan, as administrative agent, as amended, which was scheduled to mature on July 1, 2012 (the “Replaced Credit Facility”).

The Credit Facility is unsecured and repayable on the maturity date of March 7, 2017. The maximum amount of outstanding borrowings and letters of credit permitted at any one time under the Credit Facility is $250,000,000, of which, (i) up to US$25,000,000 will be available to the Company for eurocurrency loans denominated in Canadian dollars, pounds sterling and euro; (ii) up to US$30,000,000 will be available to the Canadian borrower for eurocurrency loans denominated in Canadian dollars; (iii) an amount not exceeding US$50,000,000 will be available to the Company and Canadian Borrower for the issuance of letters of credit; and (iv) up to US$30,000,000 will be available to the Company for swingline loans. The maximum amount available under the Credit Facility may be increased from time to time up to $400,000,000 at the request of the Company, subject to customary conditions contained in the Credit Facility. The proceeds of the Credit Facility are to be used to refinance the indebtedness under the Replaced Credit Facility and for working capital and other general corporate purposes of the Company and its subsidiaries.

Borrowings in U.S. dollars under the Credit Facility will, at the election of the Company, bear interest at (a) the Adjusted LIBO rate for specified interest periods plus a margin determined with reference to the Company’s consolidated leverage ratio or (b) a floating rate equal to the greatest of (i) JPMorgan’s prime rate, (ii) the federal funds rate plus 0.5% and (iii) the Adjusted LIBO rate for a one month interest period plus 1.0%, plus, in each case, a margin determined with reference to the Company’s consolidated leverage ratio. Swingline loans will, at the election of the Company, bear interest at (i) the rate described in clause (b) above or (ii) a rate to be agreed upon by the Company and JPMorgan.

The applicable margin for Adjusted LIBO rate revolving loans ranges between 1.0% and 2.0% depending on the Company’s consolidated leverage ratio, as compared with a range of 2.25% to 3.25% under the Replaced Credit Facility, and the applicable margin for alternate base rate revolving loans ranges between 0.0% and 1.0% depending on the Company’s consolidated leverage ratio, as compared with a range of 1.25% to 2.25% under the Replaced Credit Facility.

Borrowings in Canadian dollars under the Credit Facility will, at the election of the Company, bear interest at (a) the Canadian deposit offered rate plus 0.1% for specified interest periods plus a margin determined with reference to the Company’s consolidated leverage ratio or (b) a floating rate equal to the greater of (i) the Canadian prime rate and (ii) the Canadian deposit offered rate for a one month interest period plus 1.0%, plus, in each case, a margin determined with reference to the Company’s consolidated leverage ratio.

Borrowings in agreed upon currencies other than U.S. or Canadian dollars will bear interest at the LIBO rate for specified interest periods plus a margin determined with reference to the Company’s consolidated leverage ratio.

G&K Services, Co., a wholly-owned subsidiary of the Company, has guaranteed the obligations of the Company and Canadian Borrower under the Credit Facility. Additional subsidiaries of the Company may become guarantors under the Credit Facility in accordance with the terms set forth in the Credit Facility, pursuant to which any such U.S. subsidiary would guarantee the obligations of the Company and Canadian Borrower under the Credit Facility and any such Canadian subsidiary would guarantee the obligations of Canadian Borrower under the Credit Facility.

The Credit Facility contains customary covenants, including, without limitation, covenants applicable to the Company and its subsidiaries limiting, among other things, indebtedness, liens, substantial asset sales and mergers, which are similar to those contained in the Replaced Credit Facility. Most of these restrictions are subject to certain minimum thresholds and exceptions.

In particular, the Credit Facility also contains the following financial covenants:

In addition, the Credit Facility has customary events of default, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of a representation or warranty, bankruptcy or insolvency proceedings, change of control, ERISA matters, environmental liability and cross-default to other debt agreements and certain contracts. Upon an event of default, by agreement of lenders representing a majority of the outstanding commitments, the lenders may terminate the lending commitments under the Credit Facility and accelerate amounts outstanding thereunder (which occurs automatically in the event of various bankruptcy and insolvency proceedings).

This summary is qualified in its entirety by references to the terms of the Credit Facility attached hereto as Exhibit 10.1 which is incorporated herein by reference.
