NEW YORK (Standard&Poor's) March 13, 2007--Standard&Poor's Ratings Services said today that it affirmed its 'B' corporate credit ratings on Berry Plastics Holding Corp. and Covalence Specialty Materials Corp. following the announcement that their holding company parents have entered into a definitive agreement to merge in a stock-for-stock transaction. The transaction is expected to close in April 2007, subject to regulatory approval. If the transaction is consummated, the outlook on the combined company will be stable. "The affirmation of the corporate credit ratings recognizes the strength of the merged business and the potential that the company will improve its highly aggressive financial profile to acceptable levels for the current ratings within the next couple of years," said
