2013 Annual Meeting Presentation to Stockholders

At the 2013 Annual Meeting, Joseph Carleone, President and Chief Executive Officer of the Company, delivered to the stockholders in attendance the slide presentation attached as Exhibit 99.1 to this report (the "2013 Stockholders' Presentation"). The 2013 Stockholders' Presentation relates to a review of the Company's activities during the year ended September 30, 2012 and strategic objectives for the year ending September 30, 2013.

The 2013 Stockholders' Presentation includes non-GAAP measures as a supplement to financial results based on GAAP. A reconciliation of the non-GAAP measures to the most directly comparable GAAP measures is included herein. Dollar amounts are presented in thousands, except per share amounts.

Adjusted EBITDA. Adjusted EBITDA is not a financial measure calculated in accordance with GAAP and should not be considered as an alternative to income
(loss) from continuing operations as a performance measure. Adjusted EBITDA is presented solely as a supplemental disclosure because management believes that each is a useful performance measure that is widely used within the industries in which the Company operates. In addition, EBITDA measures are significant measurements for covenant compliance under the Company's revolving credit facility. Each EBITDA measure is not calculated in the same manner by all companies and, accordingly, may not be an appropriate measure for comparison.
