                                      TO
                        NEWPORT NEWS SHIPBUILDING INC.
             DEFERRED COMPENSATION PLAN FOR NONEMPLOYEE DIRECTORS

     The Newport News Shipbuilding Inc. Deferred Compensation Plan for

     1.   A new Section 6.06 is hereby added to read as follows:

          "6.06  Termination Upon a Change in Control.  Notwithstanding anything
          to the contrary in the Plan, and notwithstanding any Participant's
          prior elections with respect to distribution of the Participant's
          Deferred Compensation Account, upon the occurrence of a Change in
          Control (within the meaning of the Company's Change in Control
          Severance Benefit Plan for Key Executives), the Company shall pay each
          Participant as soon as practicable following such Change in Control an
          amount in cash equal to the amount credited to such Participant's
          Deferred Compensation Account, and this Plan shall terminate following
          such payments.  For purposes of this Section 6.06, (i) the amount
          credited to the portion of a Participant's Deferred Compensation
          Account (including any Company Match Account) that is deemed to be
          invested in the Newport News Shipbuilding Inc. Stock Index shall be
          valued assuming that the per share price of the Company's common stock

          price paid or to be paid by any person in connection with a tender
          offer for the shares of Company common stock (if such offer price is
          higher than the then current market per share price of the Company's
          common stock), and (ii) the amount credited to each Participant's
          Deferred Compensation Account shall be determined immediately
          following such Change in

          Control (and without regard to whether any such date would otherwise
          be a Valuation Date)."

     ---------------------
continue in full force and effect in accordance with the terms thereof on the
date hereof.

     Governing Law.  This Amendment shall be governed by and construed in

     The parties do hereby amend the Trust Agreement, effective immediately
prior to the Consummation of the Offer (as defined in the Agreement and Plan of
Merger among General Dynamics Corporation, Grail Acquisition Corporation and the

     FIRST:  Section 1(g) is amended in its entirety to read as follows:

     "Upon a Change in Control, the Company shall as soon as possible but in no

     Control, as defined herein, make an irrevocable contribution to the Trust
     in an amount that is sufficient to fund the Trust in an amount equal to no
     less than 100% of the amount necessary to pay each Participant or
     Beneficiary the benefits to which Participants or their Beneficiaries are
     entitled pursuant to the terms of the Arrangements as of the date on which
     the Change in Control occurred (assuming for such purpose, with respect to
     benefits that are not payable unless a Participant's employment is
     terminated, that each Participant's employment were terminated immediately
     following such Change in Control under circumstances that would entitle the
     Participant to severance or other applicable benefits under the
     Arrangements), and to fund an expense reserve for the Trustee in the amount
     of $125,000.00.  The Company may designate that the aggregate contribution
     be treated as separate contributions to one or more Sub-Accounts that may
     be established in respect of each Arrangement listed on Attachment A, and
     the Trustee shall treat each such separately designated contribution as a
     Sub-Account hereunder, for purposes of determining whether any such
     contributions may be returned to the Company in accordance with the
     provisions of Section 5."

     SECOND:  Section 5 is amended by adding the following at the end thereof:
     ------

     "; provided, however, that to the extent that all or any portion of an
        --------  -------
     aggregate contribution to the Trust is required to be treated by the
     Trustee under Section 1(g) as held under a Sub-Account hereunder, the
     Company may direct the Trustee to return to the Company or divert to others
     any of the Trust assets solely in respect of such Sub-Account after all
     payments of benefits have been made to Participants and their Beneficiaries
     pursuant to the terms of the specific Arrangement to which such Sub-Account
     applies, without regard to whether all payments of benefits under all the
     Arrangements listed on Attachment A have been made to Participants and
     their Beneficiaries in the aggregate pursuant to the terms thereof."

     THIRD:  Section 15(b) is amended by adding a new clause (vi) thereof to
     -----
     read as follows:

     "(vi)  the Consummation of the Offer (as defined in the Agreement and Plan
            of Merger among General Dynamics Corporation, Grail Acquisition
            Corporation and the Company, dated as of April 24, 2001)."

     Full Force and Effect.  Except as expressly amended hereby, the Trust
     ---------------------
Agreement shall continue in full force and effect in accordance with the terms
thereof on the date hereof.
