Due to the net loss incurred by the Corporation for the six-month period ended June 28, 1998, the assumed exercise of stock options and stock issuable under employee benefit plans is anti-dilutive and, therefore, is not used in the calculation of diluted earnings per share included in the financial statements. As a result, the financial statements reflect diluted earnings per share equal to basic earnings per share for the six-months ended June 28, 1998--both a loss of $9.65 per share. </FN>
