                               SECOND AMENDMENT
                                      TO
                        NEWPORT NEWS SHIPBUILDING INC.
                          DEFERRED COMPENSATION PLAN

     The Newport News Shipbuilding Inc. Deferred Compensation Plan is hereby
amended, effective September 1, 1999, in the following respects:

     1.   Section 5.05 is amended to read as follows:

             5.05  Deferral Period. Coincident with each election to contribute,
                   a Participant shall elect a deferral period applicable to
                   Annual Earnings Deferrals, Annual Incentive Deferrals, Stock
                   Grant Deferrals, and any related Company Match. The deferral
                   period shall be at least two years and shall not continue
                   beyond the last day of the calendar year in which the
                   Participant attains age sixty-five (65).

     2.   Article V is amended by adding a new Section 5.07, to read as follows:

             5.07  Stock Grant Deferrals:  The cash equivalent value of
                   performance share awards issued to and earned by Participants
                   shall be eligible for deferral under this Plan. Prior to
                   October 1 of the year preceding the year in which the
                   performance shares are scheduled to vest, each Participant
                   must make a written election to reduce the cash equivalent of
                   those shares by a percentage thereof or by a flat dollar
                   amount and to have such amounts contributed to his Deferred
                   Compensation Account.

                   Such election shall be made on a form provided by the Plan
                   Administrator, and must be returned to the Plan Administrator
                   prior to the applicable October 1. Such election form shall
                   state the percentage or amount by which the Participant
                   desires to reduce the cash equivalent of his performance
                   shares. If the amount of the reduction is expressed as a
                   percentage such percentage must be in whole numbers in
                   increments of ten percent (10%), not less than ten percent
                   (10%), and not more than one hundred percent (100%). If the
                   amount of the reduction is expressed as a flat dollar amount,
                   such amount must be at least $1,000 and an even multiple of
                   one thousand dollars ($1,000) and may not exceed the cash
                   equivalent value of the Participant's earned performance
                   shares, as valued on the closing price of such shares on the
                   New York Stock Exchange on the date such shares are scheduled
                   to vest.

                    The deferral elections described in this section shall not
                    apply to stock options or restricted stock awarded to a
                    Participant, except that restricted stock may be subject to
                    a deferral election if the award has been made in lieu of
                    performance shares and provides for the vesting of such
                    stock upon the attainment of one or more performance goals.
                    The deferral elections described in this section shall be
                    eligible for the Company Match set forth in Section 5.03(b),
                    provided the Participant elects the Newport News
                    Shipbuilding Inc. Stock Index as the Hypothetical Investment
                    Alternative and elects a deferral period of at least three
                    (3) years under Section 5.05 with respect to the deferral.

     IN WITNESS WHEREOF, these amendments are hereby executed this _____ day of
November, 1999.

                                THIRD AMENDMENT
                                      TO
                        NEWPORT NEWS SHIPBUILDING INC.
                          DEFERRED COMPENSATION PLAN

     The Newport News Shipbuilding Inc. Deferred Compensation Plan is hereby
amended, effective December 14, 1999, in the following respects:

          Section 6.01 is amended to read as follows:

          6.01  Vesting.  The amount credited to a Participant's Deferred
          Compensation Account and so much of the Company Match Account as is
          attributable to contributions made pursuant to Section 5.03(a) shall
          be at all times and in all events one hundred percent (100%) vested
          and nonforfeitable. The amount credited to a Participant's Company
          Match Account that is attributable to contributions made pursuant to
          Section 5.03(b) shall become vested and nonforfeitable upon expiration
          of the minimum deferral period required under Section 5.03(b). Unless
          otherwise authorized by the Plan Administrator or his delegee, the
          amount credited to a Participant's Company Match Account that is
          attributable to contributions made pursuant to Section 5.03(b) shall,
          in the event of termination of employment prior to the expiration of
          the minimum deferral period required under Section 5.03(b), be subject
          to the following vesting provisions:

               (i)  Upon the Participant's retirement or death, a pro rata
                    portion of the Company Match Account shall vest. This pro
                    rata portion shall be a fraction, the numerator of which is
                    the number of whole years the Participant's compensation was
                    actually deferred and the denominator of which is three (3).

               (ii) Upon termination of employment for any reason other than
                    retirement or death, the Participant's Company Match Account
                    shall be forfeited.

               Notwithstanding any other provision of this Section, in the event
               of a Change in Control, all amounts credited to a Participant's
               Company Match Account will immediately vest and become
               nonforfeitable.

                                FIRST AMENDMENT
                                      TO
                        NEWPORT NEWS SHIPBUILDING INC.
                             ANNUAL INCENTIVE PLAN

     The Newport News Shipbuilding Inc. Annual Incentive Plan is hereby amended,
effective January 1, 2000, as follows:

     1.   Article V, Section C, is amended to read as follows:

          Pro-rated Award - At the discretion of the Company, a Participant's
          annual award may be prorated in the event he or she participates in
          the Plan for less than an entire year or moves into or from a position
          covered under a different schedule of awards.  In the event an award
          is prorated, the award for which the Participant qualifies will be
          determined by dividing the number of whole calendar months that the
          Participant participated in the Plan by twelve (12).  The resulting
          fraction will then be multiplied by the percentage of Salary, as
          determined in accordance with the applicable schedule, to determine
          the prorated award.

     2.   A new Section F is added to Article V, to read as follows:

          Payment of Awards Upon Change in Control - In the event of a Change in
          Control within the meaning of the Company's Change in Control
          Severance Benefit Plan for Key Executives, annual awards shall be paid
          on a pro rata basis of the target percentage of Salary for the year in
          which the Change in Control occurs.  The pro rata portion of the award
          shall be a fraction, the numerator of which is the number of whole
          calendar months that the Participant participated in the Plan prior to
          the Change in Control and the denominator of which is twelve (12).

     3.   A new article XIII is added, to read as follows:

          Article XIII.  Successors

          The Plan may and shall be assigned or transferred to, and shall be
          binding upon, any successor of NNS. The term "successor" shall mean
          any person, firm, corporation, or business entity which at any time,
          whether by merger, purchase or otherwise, acquires all of, or a
          controlling interest in, the capital stock or other ownership
          interest, assets, or business of NNS. Notwithstanding such assignment,
          NNS shall remain, with such successor, jointly and severally liable
          for all obligations under the Plan.
