LOS ANGELES, April 18, 2001 (PRIMEZONE) -- Northrop Grumman Corporation (NYSE:NOC) today announced proration factors for its tender offer for Litton Industries Inc., which expired at midnight E.D.T. on April 2, 2001.

Based on the tender numbers reported by the depositary, EquiServe Trust Company, the total number of Litton common shares tendered for Northrop Grumman preferred stock was 24,962,376, which substantially exceeds the maximum preferred stock consideration available in the offer.

As a result, the company said all tenders of Litton common shares for Northrop Grumman preferred stock are subject to a proration factor of 0.175269414.

The total number of Litton common shares tendered for Northrop Grumman common stock, together with the total number of common shares tendered for Northrop Grumman preferred stock that could not be satisfied due to proration, was 16,352,503, based on numbers reported by the depositary. Of that amount, 11,237,071 shares were subject to Alternative A elections and 5,115,432 shares were subject to Alternative B elections.

As a result of these amounts, the common shares tendered for Northrop Grumman common stock with an Alternative A election are subject to a proration factor of 0.790733996. There will be no proration of (a) common shares tendered (or deemed tendered as a result of proration) for Northrop Grumman common stock with an Alternative B election, or (b) preferred shares tendered for cash.

EquiServe reported that 44,660,440 common shares and 240,632 preferred shares of Litton stock were validly tendered and not properly withdrawn. There were 45,900,722 common shares and 410,643 preferred shares of Litton stock outstanding as of March 28, 2001, according to Litton and its transfer agent, and the number of Litton shares accepted for purchase or exchange by Northrop Grumman represent approximately 97.3% of such outstanding common shares and 58.6% of such outstanding preferred shares.

Based on these numbers, Northrop Grumman said it will issue the full allotment of 13,000,000 shares of its common stock and 3,500,000 shares of its preferred stock available for issuance pursuant to the offer. Proration is necessary because the number of such securities requested by tendering holders of Litton common shares exceeds the respective amounts of securities available in the offer.
