Item 1.01 Entry into a Material Agreement

On December 30, 2010, Monro Muffler Brake, Inc. (the “Company”) entered into Employment Agreements with its President, John W. Van Heel, its Executive Vice President-Store Operations, Joseph Tomarchio Jr. and its Executive Vice President and Chief Financial Officer, Catherine D’Amico. All three Agreements became effective on January 1, 2011 and have a four-year term.

Under the Agreements, Messrs. Van Heel and Tomarchio and Ms. D’Amico (i) will be paid an annual base salary of $445,000, $475,000 and $330,000, respectively; (ii) will be eligible to earn a target bonus, pursuant to the terms of the Company’s bonus plan, up to, in the case of Mr. Van Heel, 100% of his base salary, and, in the case of Mr. Tomarchio and Ms. D’Amico, 87.5% of the executive’s base salary, upon the achievement of certain predetermined corporate objectives and (iii) will participate in the Company’s other incentive and welfare and benefit plans made available to executives. The base salary of each executive will be reviewed annually by the Compensation Committee and may be increased to reflect the performance and responsibilities of each such executive.

Finally, each executive is entitled to certain payments upon death, disability, a termination without Cause (as defined in the Agreements), a resignation by the executive for Good Reason (as defined in the Agreements) or a termination in the event of a Change in Control of the Company (as defined in the Agreements), all as set forth in detail in the Agreement. In accordance with the policy adopted by the Compensation Committee in May 2009, the executives contracts do not include any provision for the payment of what is commonly referred to as an “excise tax gross-up” with respect to payments received by an executive upon a Change in Control (as defined in the Agreements).

Also, on December 30, 2010 and in consideration of the executives’ execution of the Agreements, the Company’s Compensation Committee awarded to Messrs. Van Heel and Tomarchio and Ms. D’Amico a five (5) year option to purchase 150,000, 120,000 and 90,000 shares of Common Stock, respectively, at an exercise price of $35.31 per share (the closing price of the Company’s stock on the date of the award), pursuant to the Company’s 2007 Stock Incentive Plan (together, the “Executive Options”). Each of the Executive Options will vest equally over four (4) years, beginning December 29, 2011.

A copy of the Company’s Employment Agreements with Messrs. Van Heel and Tomarchio and Ms. D’Amico are attached to this Current Report as Exhibits 99.1, 99.2 and 99.3, respectively, and incorporated herein by reference.

Item 8.01 Other Events

Today, the Company’s Compensation Committee awarded to Robert G. Gross, Chief Executive Officer of the Company, a five (5) year option to purchase 150,000 shares of Common Stock, at an exercise price of $33.62 per share (the closing price of the Company’s stock on the date of the award). Like the Executive Options, the option grant to Mr. Gross will vest equally over four (4) years, beginning January 3, 2012. The option was granted in anticipation of Mr. Gross’s continued service to the Company as Chief Executive Officer and/or as a member of the Company’s Board of Directors during the term of the option.
