Carol L. Roberts, Senior Vice President, Industrial Packaging, has established a Rule 10b5-1 trading plan (the “Trading Plan”) to sell a portion of her holdings of Company common stock as part of her personal financial planning strategy for asset diversification and liquidity.

Her Trading Plan provides for the sale of up to 37,699 shares of her Company stock and up to 18,750 shares that she may acquire upon exercise of employee stock options. Of these options, 3,750 expire on October 9, 2011; 7,500 expire on April 9, 2012; and 7,500 expire on October 8, 2012. The exercise price of the options is currently above the Company’s stock price.

10b5-1 Plans Generally

The Trading Plan described above was adopted in accordance with guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934, and the Company’s policies regarding transactions in its securities. Rule 10b5-1 permits individuals who are not in possession of material, non-public information at the time the plan is adopted to establish pre-arranged plans to buy or sell company stock. Once a plan is established, the individual retains no discretion over purchases or sales under the plan, and the transactions are executed through a broker on or after specified dates, whether or not the individual subsequently acquires material non-public information about the company.

Any transactions under these plans will be disclosed publicly through Form 144 and Form 4 filings with the Securities and Exchange Commission when due.
