Explanatory Note

This Current Report is being filed to supplement and correct disclosure in the definitive proxy statement on Schedule 14A filed by Mac-Gray Corporation (“Mac-Gray”) with the U.S. Securities and Exchange Commission (the “SEC”) on December 4, 2013 (“Proxy Statement”).  The Proxy Statement relates to the special meeting of Mac-Gray stockholders to be held on January 8, 2014 at which Mac-Gray stockholders will be asked to consider and vote upon a proposal to adopt a merger agreement pursuant to which Mac-Gray would be acquired by Spin Holdco Inc., a wholly-owned subsidiary of CSC ServiceWorks, Inc. (“CSC”), and other related proposals.  By correcting these statements, Mac-Gray is not indicating that the Proxy Statement contained any material misstatements. No other changes are being made to the Proxy Statement.

ITEM 8.01. Other Events.

The discussion contained in the second full paragraph on page 53 of the Proxy Statement with respect to Mac-Gray’s Projections is hereby amended and supplemented by replacing such paragraph with the following:

The Projections were prepared in June 2013 in the context of the business, economic, regulatory, market and financial conditions that existed at that time, and have not been updated to reflect revised prospects for our business, changes in general business, economic, regulatory, market and financial conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the projections were prepared, other than changes to the assumptions for number and approximate multiple at which machines are acquired in the Management Financial Projections with Acquisitions case to increase the number of machines acquired from 3,000 machines per year assumed in June 2013 to the 10,000 — 26,600 machines per year described above and in the Projections shown below. The Projections are not necessarily indicative of future performance, which may be significantly more favorable or less favorable than as set forth below. The Projections cover multiple years, and such information by its nature becomes less reliable with each successive year. They should not be utilized as public guidance and will not be provided in the ordinary course of our business in the future.
