                           CALCULATION OF FILING FEE

          Transaction Valuation*                      Amount of Filing Fee
    --------------------------------------------------------------------------
            $6,579,556,144.76                            $1,315,911.23


*Estimated for purposes of calculating the amount of the filing fee only. This
calculation assumes the purchase of all of the issued and outstanding shares of
(a) common stock, par value $0.625 per share (the "Common Shares"), of TRW Inc.,
an Ohio corporation (the "Company"), (b) Cumulative Serial Preference Stock II,
$4.40 Convertible Series 1, no par value per share (the "Series 1 Preference
Shares"), and (c) Cumulative Serial Preference Stock II, $4.50 Convertible
Series 3, no par value per share (the "Series 3 Preference Shares" and, together
with the Common Shares and the Series 1 Preference Shares, the "Capital
Shares"), for shares of common stock, par value $1.00 per share (the "Northrop
Grumman Common Stock"), of Northrop Grumman Corporation, a Delaware corporation
("Northrop Grumman"). Each Common Share may be exchanged for a share of the
Northrop Grumman Common Stock equal to the exchange ratio (as defined below).
Each Series 1 Preference Share and each Series 3 Preference Share may be
exchanged for a number of shares of Northrop Grumman Common Stock equal to the
then-effective conversion rate for the Series 1 Preference Shares and the Series
3 Preference Shares, as the case may be, multiplied by the exchange ratio. As of
March 28, 2002, there were 126,762,644 Common Shares, 28,660 Series 1 Preference
Shares and 53,324 Series 3 Preference Shares outstanding. The amount of the
filing fee, calculated in accordance with Rule 0-11 of the Securities Exchange
Act of 1934, equals 1/50th of one percent of the value of the Common Shares,
Series 1 Preference Shares and Series Preference 3 Shares proposed to be
acquired.
