436 SEVENTH AVENUE, PITTSBURGH, PA, 15219

**Item 4. Purpose of Transaction**

The Reporting Persons purchased the Shares based on the Reporting Persons' belief that the Shares, when purchased, were substantially undervalued. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons are supportive of management's current plan to increase the Issuer's profitability, the strong focus on free cash flow generation and the use of such funds to reduce debt and repurchase Shares.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. Depending on various factors including, without limitation, the Issuer's financial position, results and strategic direction, actions taken by the Issuer's management and Board of Directors (the "Board"), other investment opportunities available to the Reporting Persons, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with the Issuer's management and Board, engaging in discussions with shareholders of the Issuer or other third parties about the Issuer and the Reporting Persons' investment, making recommendations or proposals to the Issuer concerning changes to the Issuer's operations, governance or capitalization, potential business combinations or dispositions involving the Issuer or certain of its businesses, or suggestions for improving the Issuer's financial and/or operational performance, acquiring additional Shares, disposing of some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, including swaps and other derivative instruments, or changing their intention with respect to any and all matters referred to in Item 4.
