Safe Harbor Provision and Disclaimer Statements in this presentation that are not historical facts are forward-looking statements. Forward-looking statements are based on our current expectations and beliefs and involve risks, uncertainties and assumptions. Management believes its assumptions are reasonable; however, undue reliance should not be placed on such estimates, which are based on current expectations. There are many factors that impact these forward-looking statements that we cannot predict accurately. Further, RockTenn’s businesses are subject to a number of general risks that would affect any such forward-looking statements including, among others, decreases in demand for products; increases in energy, raw materials, shipping and capital equipment costs; reduced supply of raw materials; fluctuations in selling prices and volumes; intense competition; the potential loss of certain customers; and adverse changes in general market and industry conditions. Such risks and other factors that may impact management's assumptions are more particularly described in our filings with the Securities and Exchange Commission, including under the caption "Business -- Forward-Looking Information" and "Risk Factors" in our Annual Report on Form 10-K for the year ended September 30, 2010. The information contained herein speaks as of the date hereof and we do not have or undertake any obligation to update such information as future events unfold. We may from time to time be in possession of certain information regarding RockTenn that applicable law would not require us to disclose to the public in the ordinary course of business, but would require us to disclose if we were engaged in the purchase or sale of our securities. This presentation shall not be considered to be part of any solicitation of an offer to buy or sell RockTenn securities. This presentation also may not include all of the information regarding RockTenn that you may need to make an investment decision regarding RockTenn securities. Any such investment decision should be made on the basis of the overall mix of information regarding RockTenn that is publicly available as of the date of such decision. We have included financial measures that are not prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The non-GAAP financial measures presented are not intended to be a substitute for GAAP financial measures, and any analysis of non-GAAP financial measures should be used only in conjunction with results presented in accordance with GAAP Reconciliations of non-GAAP financial measures to GAAP financial measures are posted under the Investors section of our website at www.rocktenn.com. 16

Use of Non-GAAP Financial Measures and Reconciliations Below, we define the non-GAAP financial measures, provide a reconciliation of each non-GAAP financial measure to the most directly comparable financial measure calculated in accordance with GAAP, and discuss the reasons that we believe this information is useful to management and may be useful to investors. These measures may differ from similarly captioned measures of other companies in our industry. Non-GAAP Measures Our definitions of Credit Agreement EBITDA and Segment EBITDA may differ from other similarly titled measures at other companies. Credit Agreement EBITDA (as defined) and Adjusted EBITDA (as defined) are not defined in accordance with GAAP and should not be viewed as alternatives to GAAP measures of operating results or liquidity. RockTenn management believes that net income is the most directly comparable GAAP measure to Credit Agreement EBITDA (as defined) and Segment Income is the most directly comparable GAAP measure to Segment EBITDA. 17

Non-GAAP Measures: Credit Agreement EBITDA and Total Funded Debt (as defined) “Credit Agreement EBITDA” is calculated in accordance with the definition of “EBITDA” contained in the Company’s Senior Secured Credit Facility. Credit Agreement EBITDA is generally defined as Consolidated Net Income plus: consolidated interest expense (interest expense, interest and other income (expense)), taxes of the consolidated companies, depreciation and amortization expense of the consolidated companies determined in accordance with GAAP, non-cash charges related to the expensing of stock options, certain cash and non-cash restructuring charges. For additional information on the calculation see our Amended and Restated Credit Agreement dated Agreement, as of March 5, 2008, filed as Exhibit 4.1 to our Quarterly Report on Form 10-Q for the quarter ended December 31, 2009. “Total Funded Debt” is calculated in accordance with the definition contained in the Company’s Senior Secured Credit Facility. Total Funded Debt is generally defined as aggregate debt obligations reflected in our balance sheet, less the hedge adjustments resulting from terminated and existing fair value interest rate derivatives or swaps, plus additional outstanding letters of credit not already reflected in debt, plus debt guarantees. In fiscal 2008, Total Funded Debt is reduced by deferred cash associated with certain debt outstanding at that time. 18

Non-GAAP Measures: Credit Agreement EBITDA and Total Funded Debt Our management uses Credit Agreement EBITDA and Total Funded Debt to evaluate compliance with RockTenn’s debt covenants and borrowing capacity available under its Senior Secured Credit Facility. Management also uses Credit Agreement EBITDA as a measure of our Company’s core operating performance. Management believes that investors also use these measures to evaluate the Company’s compliance with its debt covenants and available borrowing capacity. Management also believes that investors use Credit Agreement EBITDA as a measure of our Company’s core operating performance. Borrowing capacity is dependent upon, in addition to other measures, the “Total Funded Debt/EBITDA ratio” or the “Leverage Ratio,” which is defined as Total Funded Debt divided by Credit Agreement EBITDA. 19

Non-GAAP Measures: Net Debt We have defined the non-GAAP measure Net Debt to include the aggregate debt obligations reflected in our balance sheet, less the hedge adjustments resulting from terminated and existing fair value interest rate derivatives or swaps, the balance of our cash and cash equivalents, restricted cash (which includes the balance sheet line items restricted cash and restricted cash and marketable debt securities) and certain other investments that we consider to be readily available to satisfy such debt obligations. Our management uses Net Debt, along with other factors, to evaluate our financial condition. We believe that Net Debt is an appropriate supplemental measure of financial condition and may be useful to investors because it provides a more complete understanding of our financial condition before the impact of our decisions regarding the appropriate use of cash and liquid investments. 20

Non-GAAP Measures: Adjusted Net Income and Adjusted Earnings Per Diluted Share We also use the non-GAAP measures “adjusted net income” and “adjusted earnings per diluted share”. Management believes these non-GAAP financial measures provide our board of directors, investors, potential investors, securities analysts and others with useful information to evaluate the performance of the Company because it excludes restructuring and other costs, net, the alternative fuel mixture credit and cellulosic biofuel producer credit and other specific items that management believes are not indicative of the ongoing operating results of the business. The Company and the board of directors use this information to evaluate the Company’s performance relative to other periods. 21
