                            CALCULATION OF FILING FEE
================================================================================
      Transaction Valuation*                          Amount of Filing Fee
--------------------------------------------------------------------------------
          $6,487,486,707.68                                 $700,648.56
================================================================================

* 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 I, 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 November 2,
2001, the most recent available public information, there were 126,286,307
Common Shares outstanding. As of February 9, 2001, the most recent available
public information, there were 31,710 Series 1 Preference Shares and 59,216
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.
