(1)   Pursuant to the Plan, before each annual or special meeting of the
      shareholders of TRW Inc., each Plan participant with an account balance in
      the TRW Stock Fund (an investment fund within the Plan consisting solely
      of TRW Common) is sent a copy of the proxy solicitation material. In
      addition, each participant is sent forms for advising the three individual
      co-trustees for the TRW Stock Fund (the "Co-Trustees") how to vote the
      shares of TRW Common held for the participant's account. Upon receipt of
      instructions from each Plan participant, the Co-Trustees vote the shares
      as instructed. The Co-Trustees have the right to vote, at their
      discretion, the shares of TRW Common for which no voting instructions are
      received from participants.
     
(2)   Pursuant to the Plan, participants may make contributions to one or more
      of nine investment funds, including the TRW Stock Fund. Company
      contributions to the Plan are made exclusively to the TRW Stock Fund.
      Subject to certain restrictions, a participant may elect to withdraw the
      value of his or her account in the Plan, including that portion of his or
      her account in the TRW Stock Fund. Withdrawals from the TRW Stock Fund are
      currently paid in whole shares. A participant may elect at any time to
      transfer funds from one investment fund under the Plan to another fund.
      Such elections might have the effect of requiring the Plan to dispose of
      shares and to use the proceeds therefrom to fund such transfer. In the
      case of a tender offer for TRW Common, the Co-Trustees will tender or not
      tender the shares held for participants' accounts in accordance with
      directions received from participants; provided, however that (i) the
      Co-Trustees will determine whether or not to tender shares for which no
      valid directions are received from Plan participants in their discretion;
      and (ii) directors and certain officers of TRW do not have the right to
      direct the Co-Trustees as to whether shares of TRW Common attributable to
      their accounts should be tendered.

ITEM 5.       OWNERSHIP OF FIVE PERCENT OR LESS OF A CLASS:
     
              If this statement is being filed to report the fact that as of the
date hereof the reporting person has ceased to be the beneficial owner of more
than five percent of the class of securities, check the following [ ].
     
ITEM 6.       OWNERSHIP OF MORE THAN FIVE PERCENT ON BEHALF OF ANOTHER PERSON:
     
              The Plan is a combined profit-sharing and employee stock ownership
plan within the meaning of Section 4975(e)(7) of the Internal Revenue Code. That
part of the Plan comprised of a fund in which Company contributions are invested
in TRW Common is an employee stock ownership plan ("ESOP"), while the remaining
funds form a profit-sharing plan. All shares of TRW Common held by the Plan are
held for the benefit of participants. Dividends paid in respect of shares held
by the Plan are credited to the account of the participants except that
dividends paid to the Plan on shares of TRW Common held by the ESOP are either
paid in cash to Plan participants or, at the Company's discretion, used to repay
any ESOP Loan (in which case participants' accounts will be credited with an
equivalent amount of TRW Common).
