     WHEREAS, all conditions necessary to authorize the execution and delivery

Maturity of principal or on a Redemption Date as provided herein will be paid to
the Person to whom principal is payable. Any such interest that is not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holders on such Regular Record Date and may either be paid to the Person or
Persons in whose name the Series A Senior Notes are registered at the close of
business on a Special Record Date for the payment of such defaulted interest to
be fixed by the Trustee (in accordance with Section 307 of the Original
Indenture), notice whereof shall be given to Holders of the Series A Senior
Notes not less than ten (10) days prior to such Special Record Date, or be paid
at any time in any other lawful manner not inconsistent with the requirements of

more fully provided in the Original Indenture.

     Payments of interest on the Series A Senior Notes will include interest
accrued to but excluding the respective Interest Payment Dates. Interest
payments for the Series A Senior Notes shall be computed and paid on the basis

any such delay), in each case with the same force and effect as if made on the
date the payment was originally payable.

     Payment of the principal and interest on the Series A Senior Notes shall be
made at the office of the Paying Agent in such  currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts, with any such payment that is due at the Stated Maturity of any
Series A Senior Notes or on Redemption Date being made upon surrender of such
Series A Senior Notes to the Paying Agent. Payments of interest (including
interest on any Interest Payment Date) will be made, subject to such surrender
where applicable, at the option of the Company, (i) by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register or (ii) by wire transfer at such place and to such account at
a banking institution in the United States as may be designated in writing to
the Trustee at least sixteen (16) days prior to the date for payment by the
Person entitled thereto.  In the event that any date on which principal and
interest is payable on the Series A Senior Notes is not a Business Day, then
payment of the principal and interest payable on such date will be made on the
next succeeding day that is a Business Day (and without any interest or payment
in respect of any such delay), in each case with the same force and effect as if
made on the date the payment was originally payable.

     SECTION 104.  Denominations.  The Series A Senior Notes may be issued in
                   -------------
denominations of $1,000, or any integral multiple thereof.

     SECTION 105.  Global Securities.  The Series A Senior Notes will be issued
                   -----------------
initially in the form of one or more Global Securities registered in the name of
the Depositary (which shall be The Depository Trust Company) or its nominee.
Except under the limited circumstances described below, Series A Senior Notes
represented by such Global Securities will not be exchangeable for, and will not
otherwise be issuable as, Series A Senior Notes in

                                       5
<PAGE>

definitive form. The Global Securities described above may not be transferred
except by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or to a
successor Depositary or its nominee.

     Owners of beneficial interests in such a Global Security will not be
considered the Holders thereof for any purpose under the Indenture, and no
Global Security representing a Series A Senior Note shall be exchangeable,
except for another Global Security of like denomination and tenor to be
registered in the name of the Depositary or its nominee or to a successor
Depositary or its nominee or except as described below. The rights of Holders of
such Global Security shall be exercised only through the Depositary.

     A Global Security shall be exchangeable for Series A Senior Notes
registered in the names of persons other than the Depositary or its nominee only
if (i) the Depositary notifies the Company that it is unwilling or unable to
continue as a Depositary for such Global Security and no successor Depositary
shall have been appointed by the Company within 90 days of receipt by the
Company of such notification, or if at any time the Depositary ceases to be a
clearing agency registered under the Exchange Act at a time when the Depositary
is required to be so registered to act as such Depositary and no successor
Depositary shall have been appointed by the Company within 90 days after it
becomes aware of such cessation, or (ii) the Company in its sole discretion
determines that such Global Security shall be so exchangeable.  Any Global
Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Series A Senior Notes registered in such names as the
Depositary shall direct.

     SECTION 106.  Redemption.  The Series A Senior Notes are redeemable, in
                   ----------
whole or in part, at any time, and at the option of the Company, at a Redemption
Price ("Optional Redemption Price") equal to the greater of:

     (i)  100% of the principal amount of Series A Senior Notes then Outstanding
to be so redeemed, or

     (ii) the sum of the present values of the remaining scheduled payments of
principal and interest thereon (not including any portion of such payments of
interest accrued as of the Redemption Date) discounted to the Redemption Date on
a semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Adjusted Treasury Rate, plus 15 basis points, as calculated by an
Independent Investment Banker,

     plus, in either of the above cases, accrued and unpaid interest thereon to
the Redemption Date.

     The Adjusted Treasury Rate shall be calculated on the third Business Day
preceding the Redemption Date.

     Notwithstanding Section 1104 of the Original Indenture, (x) notice of
redemption under this Section 106 shall with respect to the Series A Senior
Notes be given by first-class mail, postage prepaid, mailed not less than 20 nor
more than 60 days prior to the Redemption Date, to each Holder of Series A
Senior Notes to be redeemed, at his address appearing in the Security

                                       6
<PAGE>

Register, and (y) the notice of such redemption need not set forth the
Redemption Price but only the manner of calculation thereof. The Company shall
notify the Trustee of the Redemption Price promptly after the calculation
thereof and the Trustee shall have no responsibility for such calculation.

     SECTION 107.  Sinking Fund.  The Series A Senior Notes shall not have a
                   ------------
sinking fund.

     SECTION 108.  Additional Interest. Any principal of and installment of
                   -------------------
interest on the Series A Senior Notes that is overdue shall bear interest at the
rate of 5.75% (to the extent that the payment of such interest shall be legally
enforceable), from the dates such amounts are due until they are paid or made
available for payment, and such interest shall be payable on demand.

     SECTION 109.  Paying Agent. The Trustee shall initially serve as Paying
                   ------------
Agent with respect to the Series A Senior Notes, with the Place of Payment
initially being the Corporate Trust Office of the Trustee.

     SECTION 110.  Legal Separation Procedures.
                   ---------------------------
  If Legal Separation occurs while the Series A Senior Notes are Outstanding,
either clause (a) or clause (b) below shall apply, as appropriate, and the
Company shall give the Trustee prompt notice of the Legal Separation, indicating
in its notice whether clause (a) or clause (b) below applies:

     (a) If the Company retains all or substantially all of the Transmission and
     Distribution Business, (i) the Series A Senior Notes will remain
     Outstanding as obligations of the Company, and (ii) the Company will,
     within 90 days after Legal Separation occurs, offer  or cause to be offered
     to the Holders of the Series A Senior Notes the right to exchange the
     Series A Senior Notes for  an equal aggregate principal amount of debt
     securities of the Affiliated corporation that acquires the Generation
     Business (or, at the Company's option, debt securities of a corporation of
     which such Affiliated corporation is a direct or indirect wholly-owned
     subsidiary).  Such debt securities shall be unsecured, unsubordinated debt
     obligations issued under an indenture, shall have the same maturity and
     principal amount as the Series A Senior Notes for which they may be
     exchanged, and shall have such other terms (including an interest rate) as
     the issuer of the debt securities in its sole discretion may establish;
     provided, however, that the 90-day period referred to in this clause
     110(a)(ii) may be extended as necessary to allow a registration statement
     covering such debt securities to become effective under the Securities Act
     or the indenture under which such debt securities are to be issued to be
     duly qualified under the Trust Indenture Act, to the extent such
     effectiveness or qualification is required before such debt securities may
     be legally offered.

     (b) If the Company transfers all or substantially all of the Transmission
     and Distribution Business to an Affiliated corporation, then upon such
     transfer (i) such

                                       7
<PAGE>

     Affiliated corporation shall expressly assume the due and punctual payment
     of the principal of and premium, if any, and interest on the Series A
     Senior Notes, according to their tenor, and the due and punctual
     performance and observance of all of the covenants and conditions of this
     Indenture to be performed by the Company with respect to the Series A
     Senior Notes by an indenture supplemental hereto, in form reasonably
     satisfactory to the Trustee, executed and delivered to the Trustee by such
     Affiliated corporation; (ii) the Company will, within 90 days after Legal
     Separation occurs, offer or cause to be offered, to the Holders of the
     Series A Senior Notes the right to exchange the Series A Senior Notes for
     an equal aggregate principal amount of debt securities of the Company or of
     a corporation of which the Company is a direct or indirect, wholly-owned
     subsidiary. Such debt securities shall be unsecured, unsubordinated debt
     obligations issued under an indenture, shall have the same maturity and
     principal amount as the Series A Senior Notes for which they may be
     exchanged, and shall have such other terms (including an interest rate) as
     the issuer of such debt securities in its sole discretion may establish;
     provided, however, that the 90-day period referred to in this clause
     110(b)(ii) may be extended as necessary to allow a registration statement
     covering such debt securities to become effective under the Securities Act
     or the indenture under which such debt securities are to be issued to be
     duly qualified under the Trust Indenture Act, to the extent such
     effectiveness or qualification is required before such debt securities may
     be legally offered; and (iii) the Company shall deliver to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that the
     transfer of the Transmission and Distribution Business described above and
     the supplemental indenture referred to in clause 110(b)(i) comply with this
     Section, and that all conditions precedent herein provided for relating to
     such transaction have been complied with. Upon such transfer of the
     Transmission and Distribution Business and execution and delivery of such
     supplemental indenture in accordance with this Section, such Affiliated
     corporation shall succeed to, and be substituted for, and may exercise
     every right and power of, the Company under the Indenture with respect to
     the Series A Senior Notes with the same effect as if such Affiliated
     corporation had been named as the Company herein, and thereafter the
     Company shall be relieved of all obligations and covenants under the
     Indenture with respect to the Series A Senior Notes, other than its
     obligations under clause 110(b)(ii).

          (c)  For the avoidance of doubt, it is expressly acknowledged and
agreed with respect to the Series A Senior Notes that (i) Legal Separation shall
not constitute a default in the performance, or breach, of any covenant of the
Company in the Indenture, and (ii) the provisions of Article Eight of the

on March 31, and September 30 of each year, commencing on September 30, 2001, at
the rate of 5.75% per annum, until the principal hereof is paid or made
available for payment, provided that any principal, and any such installment of
interest, that is overdue shall bear interest at the rate of 5.75% per annum (to
the extent that the payment of such interest shall be legally enforceable), from
the dates such amounts are due until they are paid or made available for
payment, and such interest shall be payable on demand. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Series A
Senior Note (or one or more Predecessor Securities) is registered at the close
of business on the Regular Record Date for such interest, which shall be the
close of business on the Business Day preceding such Interest Payment Date;
provided, that with respect to Series A Senior Notes that are not represented by
one or more Global Securities, the Regular Record Date shall be the close of
business on the 15th calendar day (whether or not a Business Day) preceding such
Interest Payment Date, provided, that interest payable at the Stated Maturity of
principal or on a Redemption Date will be paid to the Person to whom principal
is payable. Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Series A Senior Note (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Series A Senior Notes not
less than 10 days prior to such Special Record Date, or be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Series A Senior Notes may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in said
Indenture.

     Payments of interest on the Series A Senior Notes will include interest
accrued to but excluding the respective Interest Payment Dates.  Interest
payments for the Series A Senior Notes shall be computed and paid on the basis
of a 360-day year of twelve 30-day months.  In the event that any date on which
interest is payable on the Series A Senior Notes is not a Business Day, then
payment of the interest payable on such date will be made on the next succeeding
day that is a Business Day (and without any interest or payment in respect of
any such delay), in each case with the same force and effect as if made on the
date the payment was originally payable.

     Payment of the principal of and premium, if any, and interest on this
Series A Senior Note will be made at the office of the Paying Agent, in the
Borough of Manhattan, City and State of New York, in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts, with any such payment that is due at the
Stated Maturity of any Series A Senior Note or upon redemption being made upon
surrender of such Series A Senior Note to such office or agency; provided,
however, that at the option of the Company payment of interest, subject to such
surrender where applicable, may be made (i) by check mailed to the address of
the Person entitled thereto as such address shall appear in the Security
Register or (ii) by wire transfer at such place and to such account at a banking
institution in the United States as may be designated in writing to the Trustee
at least sixteen (16) days prior to the date for payment by the Person entitled
thereto.

     Reference is hereby made to the further provisions of this Series A Senior
Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                    [REVERSE OF SERIES A 5.75% SENIOR NOTE]

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of June 1, 1998, as heretofore supplemented
and amended and as further supplemented by a Fifth Supplemental Indenture dated
as of March 1, 2001 (collectively, as amended or supplemented from time to time,
herein called the "Indenture", which term shall have the meaning assigned to it
in such instrument), between the Company and The Chase Manhattan Bank, as
Trustee (herein called the "Trustee", which term includes any successor trustee
under the Indenture), and reference is hereby made to the Indenture for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the Securities and of
the terms upon which the Securities are, and are to be, authenticated and
delivered.  This Security is one of the series designated on the face hereof
(the "Series A Senior Notes") which is unlimited in aggregate principal amount.

     The Series A Notes are redeemable, in whole or in part, at any time in the
manner and with the effect provided in the Indenture.

                                       3
<PAGE>

     The Series A Notes may become exchangeable for other debt securities as
provided for in Section 110 of the Fifth Supplemental Indenture upon Legal
Separation of the Generation Business of the Company from the Transmission and
Distribution Business of the Company.

     If an Event of Default with respect to Series A Senior Notes shall occur
and be continuing, the principal of the Series A Senior Notes may be declared
due and payable in the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive certain past defaults under
the Indenture and their consequences.  Any such consent or waiver by the Holder
of this Series A Senior Note shall be conclusive and binding upon such Holder
and upon all future Holders of this Series A Senior Note and of any Series A
Senior Note issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Series A Senior Note.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Series A Senior Note shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or
trustee or for any other remedy thereunder, unless such Holder shall have
previously given the Trustee written notice of a continuing Event of Default
with respect to the Series A Senior Notes, the Holders of not less than a
majority in principal amount of the Series A Senior Notes at the time
Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity, and the Trustee shall not have received from the
Holders of a majority in principal amount of Series A Senior Notes at the time
Outstanding a direction inconsistent with such request, and shall have failed to
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity.  The foregoing shall not apply to any suit instituted by
the Holder of this Series A Senior Note for the enforcement of any payment of
principal hereof or premium, if any, or interest hereon on or after the
respective due dates expressed or provided for herein.

     No reference herein to the Indenture and no provision of this Series A
Senior Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of, premium,
if any, and interest on this Series A Senior Note at the times, place and rate,
and in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Series A Senior Note is registrable in the Security
Register, upon surrender of this Series A Senior Note for registration of
transfer at the office or agency of the Company in any place where the principal
of, premium, if any, and interest on this Series A Senior Note are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and

                                       4
<PAGE>

thereupon one or more new Series A Senior Notes and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

     The Series A Senior Notes are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Series A Senior Notes are exchangeable for a like aggregate principal amount of
Series A Senior Notes having the same Stated Maturity and of like tenor of any
authorized denominations as requested by the Holder upon surrender of the Series
A Senior Note or Series A Senior Notes to be exchanged at the office or agency
of the Company.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Series A Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Series A Senior Note be overdue,
and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary.

     All terms used in this Series A Senior Note that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

Mr. William P. Fricks
2327 West Island Road
Williamsburg, Virginia 23185

Dear Bill:

      Set forth below is a modified Section 8 to your Amended Employment
Agreement dated February 4, 1999 ("Agreement"). This modification supersedes the
current Section 8 in your Agreement and reflects the changes approved by the
Compensation Committee at its December 11, 2000 meeting.

      8.    Your pension benefit from the NNS qualified and non-qualified
            retirement plans, the Tenneco qualified and non-qualified retirement
            plans and this Agreement in combination will be equal to the larger
            of (a) or (b):

            (a)   60% of your Final Average Compensation (highest three out of
                  the last five years) as defined in the Newport News
                  Shipbuilding Inc. Supplemental Executive Retirement Plan.
                  (Note: Under the terms of your prior Employment Agreement you
                  have met both the age and the service requirements necessary
                  to receive this unreduced 60% pension benefit.)

            (b)   The amount of pension benefit that is the Actuarial Equivalent
                  (as defined in the Newport News Shipbuilding Inc. Retirement
                  Plan) of the pension benefit that you would have received if
                  you had elected to retire effective January 1, 2001 or, if
                  greater, as of any subsequent January 1.

            Your non-qualified benefit will be paid to you as an annuity or as a
            lump sum at your option, using the same factors that are used to
            calculate optional forms of benefits in the Newport News
            Shipbuilding Inc. Retirement Plan. However, the portions of your
            pension benefit payable from the Newport News Shipbuilding Inc.
            Retirement Plan and from the Tenneco qualified and non-qualified
            plans may not be available to you as a lump sum.

            Your rights under this Section 8 will survive termination of this
            Agreement.

      In all other respects, the Agreement will be unchanged, except that
effective January 1, 2001, you will be paid a base salary of not less than
$650,000 per year, which shall be
<PAGE>

subject to such adjustments as may be approved from time to time by the
Compensation Committee.

                                    Sincerely,

                                    Joseph J. Sisco
                                    Chairman
                                    Compensation and Benefits Committee

ACKNOWLEDGED AND ACCEPTED:
