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

whereof shall be given to Holders of the Series B Senior Notes not less than ten
(10) days prior to such Special Record Date, or be paid at any time in any other

as may be required by any such exchange, all as more fully provided in the
Original Indenture.

date the payment was originally payable.

         Payment of the principal and interest on the Series B Senior Notes
shall be made at the office of the Paying Agent in such coin or currency of the

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 B 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 B Senior Notes may be issued in
denominations of $1,000, or any integral multiple thereof.

         SECTION 105. Global Securities. The Series B 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

Notes represented by such Global Securities will not be exchangeable for, and
will not otherwise be issuable as, Series B Senior Notes in definitive form. The
Global Securities described above may not be transferred except by the

                                       5

<PAGE>

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 B 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 B 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 B Senior Notes registered in such names as the
Depositary shall direct.

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


         (i)  100% of the principal amount of Series B 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 twenty-five 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.

         Unless the Company defaults in the payment of the Redemption Price, on
and after the Redemption Date, interest will cease to accrue on the Series B
Senior Notes or portions thereof called for redemption.

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

                                       6

<PAGE>

         In the event of the redemption of the Series B Senior Notes in part
only, a new Series B Senior Note or Notes for the unredeemed portion will be
issued in the name or names of the Holders thereof upon surrender thereof.

         Notice of redemption shall be given as provided in Section 1104 of the
Original Indenture.

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

         SECTION 108. Additional Interest. Any principal of and installment of
interest on the Series B Senior Notes that is overdue shall bear interest at the
rate of 6.25% (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 B Senior Notes, with the Place of Payment
initially being the Corporate Trust Office of the Trustee.

         SECTION 110. Limitation on Liens. The Company will not, while any of
the Series B Senior Notes remain Outstanding, create, or suffer to be created or
to exist, any Lien upon any Principal Property of the Company or upon any shares
of stock of any Material Subsidiary of the Company, whether such Principal
Property is, or shares of stock are, now owned or hereafter acquired, to secure
any indebtedness for borrowed money of the Company, unless it shall make
effective provision whereby the Series B Senior Notes then Outstanding shall be
secured by such Lien equally and ratably with any and all indebtedness for
borrowed money thereby secured so long as any such indebtedness shall be so
secured; provided, however, that nothing in this Section shall be construed to
prevent the Company from creating, or from suffering to be created or to exist,
any Liens, or any agreements, with respect to:

         (1)      purchase money mortgages, or other purchase money liens,
                  pledges, security interests or encumbrances of any kind upon

                  kind existing on any property or any shares of stock at the
                  time of the acquisition thereof (including Liens which exist
                  on any property or any shares of stock of a Person which is
                  consolidated with or merged with or into the Company or which

                  to the Company), or conditional sales agreements or other
                  title retention agreements and leases in the nature of title
                  retention agreements with respect to any property hereafter
                  acquired; provided, however, that no such Lien shall extend to
                  or cover any other property of the Company;

         (2)      Liens upon any property of the Company or any shares of stock
                  of any Material Subsidiary of the Company existing as of the

         Dominion Resources, Inc., a corporation duly organized and existing
under the laws of Virginia (herein called the "Company", which term includes any
successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to [Cede & Co.], or registered assigns (the
"Holder"), the principal sum of __________________ Dollars ($_________) on June

Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on June 30 and December 30 of each year, commencing on

6.25% 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 B 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 B 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. 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 B 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 B 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 B 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 B Senior Notes will include interest
accrued to but excluding the respective Interest Payment Dates. Interest
payments for the Series B 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 B 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 interest on this Series B 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 B Senior Note being made upon surrender of such Series B 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 B
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.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Series B
Senior Note shall not be entitled to any benefit under the Indenture or be valid

                         REVERSE OF SERIES B 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, 2000, as heretofore supplemented
and amended and as further supplemented by an Eleventh Supplemental Indenture
dated as of June 1, 2002 (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 JPMorgan Chase Bank (formerly
known as 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 B Senior Notes") which
is unlimited in aggregate principal amount.

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

         If an Event of Default with respect to Series B Senior Notes shall
occur and be continuing, the principal of the Series B 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 B Senior Note shall be conclusive and binding upon such Holder
and upon all future Holders of this Series B Senior Note and of any Series B
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 B Senior Note.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Series B 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 B Senior Notes, the Holders of not less than a
majority in principal amount of the Series B 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 B 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 B

                                       5

<PAGE>

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 B
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 B 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 B Senior Note is registrable in the
Security Register, upon surrender of this Series B 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 B 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 thereupon one
or more new Series B 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 B 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 B Senior Notes are exchangeable for a like aggregate principal amount of
Series B 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
B Senior Note or Series B 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 B 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 B 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 B Senior Note that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.
