                        THE TRUST PREFERRED SECURITIES:

 . The Trust Preferred Securities represent undivided preferred beneficial
  ownership interests in the assets of Dominion CNG Capital Trust I (the
  Trust). The sole assets of the Trust will be the Junior Subordinated
  Debentures due 2041 issued by Consolidated Natural Gas Company (CNG), a
  subsidiary of Dominion Resources, Inc. (Dominion).

 . The Trust will apply to have the Trust Preferred Securities trade on the New
  York Stock Exchange starting within 30 days after the Trust Preferred
  Securities are issued.

 . CNG will guarantee the Trust Preferred Securities to the extent described in
  the prospectus supplement and base prospectus. The securities will not be
  guaranteed by Dominion.

 . Anticipated Closing Date: October 23, 2001.

               DISTRIBUTIONS ON THE TRUST PREFERRED SECURITIES:

 . Each Trust Preferred Security pays a quarterly distribution at an annual
  rate of 7.8% or $1.95 annually per Trust Preferred Security, if CNG pays
  interest on the Junior Subordinated Debentures.

 . CNG may defer interest payments on the Junior Subordinated Debentures on one
  or more occasions for up to 20 consecutive quarters. If CNG does defer
  interest payments, the Trust will also defer payment of distributions on the
  Trust Preferred Securities. Deferred distributions will accumulate interest
  at an annual rate of 7.8%, to the extent permitted by law.

 . If CNG redeems the Junior Subordinated Debentures held by the Trust, the
  Trust will redeem the Trust Preferred Securities. The prices and
  circumstances under which the Junior Subordinated Debentures can be redeemed
  by CNG and the amount you will receive upon redemption of your Trust
  Preferred Securities are described in the prospectus supplement.

 . If the Trust redeems the Trust Preferred Securities or is liquidated and CNG
  does not redeem its Junior Subordinated Debentures, you will receive $25
  principal amount of Junior Subordinated Debentures for each Trust Preferred
  Security you own rather than cash.

 Investing in the Trust Preferred Securities involves risks that are described
in "Risk Factors" beginning on Page S-9 of this prospectus supplement.

ABOUT THIS PROSPECTUS
SUPPLEMENT

    This document is in two parts. The first part is the prospectus supplement,
which describes the specific terms of the Trust Preferred Securities we are
offering and certain other matters relating to us and the financial condition
of CNG. The second part, the base prospectus, gives more general information
about securities we may offer from time to time, some of which does not apply
to the Trust Preferred Securities we are offering. Generally, when we refer to
the prospectus, we are referring to both parts of this document combined. If
the description of the Trust Preferred Securities, Junior Subordinated
Debentures or Guarantee in the prospectus supplement differs from the
corresponding description in the base prospectus, the description in the
prospectus supplement supersedes the description in the base prospectus.

    You should rely only on the information contained in this document or to
which this document refers you. We have not, and the underwriters have not,
authorized anyone to provide you with different information. If anyone provides
you with different or inconsistent information, you should not rely on it. This
document may only be used where it is legal to sell these securities. The
information in this document may only be accurate as of the date of this
document. CNG's business, financial condition, results of operations and
prospects may have changed since that date.

FORWARD-LOOKING
INFORMATION

    CNG has included certain information in this document which is "forward-
looking information" as defined by the Private Securities Litigation Reform Act
of 1995. Examples include discussions as to its expectations, beliefs, plans,
goals, objectives and future financial or other performance or assumptions
concerning matters discussed in this document. This information, by its nature,
involves estimates, projections, forecasts and uncertainties that could cause
actual results or outcomes to differ substantially from those expressed in the
forward-looking statement.

    CNG's business is influenced by many factors that are difficult to predict,
involve uncertainties that may materially affect actual results and are often
beyond its ability to control. CNG has identified a number of these factors in
its filings with the SEC, including its Annual Report on Form 10-K which is
incorporated by reference in this prospectus supplement, and CNG refers you to
those reports for further information.

                                      S-3


    CNG's business and financial condition is influenced by factors including
political and economic risks; market demand for energy; inflation; capital
market conditions; governmental policies, legislative and regulatory actions
(including those of the Federal Energy Regulatory Commission, the SEC, the
Environmental Protection Agency, the Department of Energy and state utility
regulatory commissions in the states in which CNG operates); industry and rate
structure; and legal and administrative proceedings. Some other important
factors that could cause actual results or outcomes to differ materially from
those discussed in the forward-looking statements include changes in and
compliance with environmental laws and policies; weather conditions and
catastrophic weather-related damage; unanticipated production difficulties at
its oil and gas properties; present or prospective wholesale and retail
competition; competition for new energy development opportunities; pricing and
transportation of commodities; risks associated with large development
projects; risks associated with the integration of the operations and employees
of Louis Dreyfus; acquisition and disposition of assets and facilities;
exposure to changes in the fair value of commodity contracts; counterparty
credit risk; and unanticipated changes in operating expenses and capital
expenditures and the effects of geopolitical events, including the threat of
domestic terrorism. All such factors are difficult to predict, contain
uncertainties that may materially affect actual results, and may be beyond
CNG's control. New factors emerge from time to time, and it is not possible for
management to predict all such factors, nor can it assess the impact of each
such factor on CNG.

    Any forward-looking statement speaks only as of the date on which it is
made, and CNG undertakes no obligation to update any forward-looking statement
to reflect events or circumstances after the date on which it is made.

THE OFFERING

Securities of the Trust

  The Trust was created by CNG to make this offering. The Trust will sell its
Trust Preferred Securities to the public and its trust common securities to
CNG. The Trust will use the proceeds from these sales to

                                      S-5


buy the 7.8% Junior Subordinated Debentures, due October 31, 2041 from CNG. The
Trust Preferred Securities and the Junior Subordinated Debentures will have
essentially the same terms.

  CNG will acquire all of the common securities of the Trust. The liquidation
amount of all the trust common securities will equal approximately 3% of the
total capital of the Trust. The trust common securities will generally rank
equally with the Trust Preferred Securities. However, in the case of specific
defaults and upon liquidation or redemption, the trust common securities will
rank junior to the Trust Preferred Securities with respect to distributions,
redemption and liquidation. Except in limited circumstances specified in the
Trust Agreement, CNG as the holder of the trust common securities will have
sole voting power with respect to matters to be voted upon by the Trust's
securityholders.

  The Trust Preferred Securities will be represented by one or more global
securities that will be deposited with, and registered in the name of The
Depository Trust Company, New York, New York (DTC) or its nominee. This means
that you will not receive a certificate for your Trust Preferred Securities
but, instead, will hold your interest through DTC's system.

Distributions

  If you purchase the Trust Preferred Securities, you will be entitled to
receive cumulative cash distributions at an annual rate of 7.8% of the
liquidation amount of $25, or $1.95 per Trust Preferred Security. Distributions
will accumulate from the date the Trust issues the Trust Preferred
Securities and will be paid quarterly in arrears on January 31, April 30, July
31 and October 31 of each year, beginning January 31, 2002.

Extension of Payment Periods

  So long as there is no event of default under the Subordinated Indenture, CNG
may defer interest payments on the Junior Subordinated Debentures for an
extension period of up to 20 consecutive quarters. CNG may defer payments in
this way more than once, but not beyond the maturity date of the Junior
Subordinated Debentures. If CNG defers interest payments on the Junior
Subordinated Debentures, the Trust will also defer distributions on the Trust
Preferred Securities. During this period you will still accumulate
distributions at an annual rate of 7.8% of the liquidation amount of $25 per
Trust Preferred Security, and you will accrue interest on unpaid distributions
at the same rate, compounded quarterly (to the extent permitted by law). Even
though you will not receive any cash distributions on your Trust Preferred
Securities during an extension period, you will be required to include accrued
distributions and interest on unpaid distributions in your gross income for
United States federal income tax purposes, even if you are a cash basis
taxpayer.

Redemption

  The Trust must redeem the Trust Preferred Securities when the Junior
Subordinated Debentures are paid at maturity on October 31, 2041, or if the
Junior Subordinated Debentures are redeemed before they mature. On or after
October 23, 2006 CNG may redeem all or part of the Junior Subordinated
Debentures, as described under

                                      S-6


SPECIFIC TERMS OF THE JUNIOR SUBORDINATED DEBENTURES--"Redemption" in this
prospectus supplement. In addition, CNG may choose to redeem all, but not less
than all, of the Junior Subordinated Debentures if specific tax events result
in specific adverse tax consequences or if the status of the Trust under the
Investment Company Act changes. If the Trust Preferred Securities are redeemed
in these circumstances, the holders will receive a redemption price as
calculated under SPECIFIC TERMS OF THE TRUST PREFERRED SECURITIES--"Redemption
of Trust Preferred Securities" in this prospectus supplement.

  Neither the Trust Preferred Securities nor the Junior Subordinated Debentures
can be redeemed at any time at the option of their holders.

CNG's Guarantee of the Trust Preferred Securities

  CNG will fully and unconditionally guarantee payments due on the Trust
Preferred Securities through a combination of the following:

 .  CNG's obligations under the Junior Subordinated Debentures;

 .  The rights of holders of Trust Preferred Securities to enforce those
   obligations;

 .  CNG's agreement to pay the expenses of the Trust; and

 .  CNG's guarantee of payments due on the Trust Preferred Securities to the
   extent of the Trust's assets, which is referred to in this prospectus as the
   Guarantee.

  If CNG does not make payments on the Junior Subordinated Debentures, the
Trust will not have sufficient funds to make payments on the Trust Preferred
Securities. The Guarantee does not cover payments on the Trust Preferred
Securities when the Trust does not have sufficient funds.

  CNG's obligations under the Trust Preferred Securities Guarantee are junior
in right of payment to all of its Senior Indebtedness, which is described under
RISK FACTORS.

  The securities will not be guaranteed by Dominion.

Ranking of the Junior Subordinated Debentures

  The Junior Subordinated Debentures are subordinate and junior in right of
payment to all of CNG's senior indebtedness which includes all of its
indebtedness for borrowed money, any of its indebtedness under commodity
contracts or interest rate or currency swap agreements and any assumption or
guarantee obligations of CNG relating to similar obligations of other parties.
The Junior Subordinated Debentures are not subordinated to CNG's obligations to
its trade creditors or indebtedness to its subsidiaries. See ADDITIONAL TERMS
OF THE JUNIOR SUBORDINATED DEBENTURES in the base prospectus.

Listing of Trust Preferred Securities

  The Trust plans to list the Trust Preferred Securities on the New York Stock
Exchange under the trading symbol "DMG PrA." You should be aware that listing
of the Trust Preferred Securities will not necessarily ensure that a liquid
trading market will be available for the Trust Preferred Securities.


                                      S-7


  If the Trust distributes the Junior Subordinated Debentures, CNG will use its
reasonable best efforts to list themon the New York Stock Exchange or any other
exchange on which the Trust Preferred Securities are then listed.

Use of Proceeds

  The Trust will invest all of the proceeds from the sale of the Trust
Preferred Securities and the trust common securities toward the purchase of the
Junior Subordinated Debentures from CNG.

  CNG intends to use the net proceeds from the sale of the Junior Subordinated
Debentures in connection with the acquisition of Louis Dreyfus Natural Gas
Corp. and for other general corporate purposes, including the repayment of
debt. See USE OF PROCEEDS in this prospectus supplement.

Recent Development

 On September 9, 2001, Dominion, CNG's parent company, agreed to acquire Louis
Dreyfus Natural Gas Corp. by merging Louis Dreyfus into a newly formed
subsidiary of Dominion. Immediately after this merger, Dominion will contribute
this subsidiary to CNG. Under the terms of the Merger Agreement, each Louis
Dreyfus shareholder will receive $20.00 in cash and a fixed exchange ratio of
0.3226 shares of Dominion common stock for each share of Louis Dreyfus common
stock. The consummation of the merger is subject to the approval of the
stockholders of Louis Dreyfus, approvals under the United States antitrust laws
and by the SEC and other customary closing conditions.

RISK FACTORS

  An investment in Trust Preferred Securities involves a number of risks.
Before deciding to buy any Trust Preferred Securities, you should carefully
consider the following information, together with the other information in
this prospectus supplement, the accompanying base prospectus and the documents
that are incorporated by reference in this prospectus supplement about risks
concerning an investment in Trust Preferred Securities.

The Trust has no independent operations or assets. If CNG does not provide
sufficient funds, the Trust will not be able to make payments on the Trust
Preferred Securities.

 .  The Trust's ability to pay amounts when they are due on the Trust Preferred
   Securities is solely dependent upon CNG's payment of amounts when they are
   due on the Junior Subordinated Debentures. If CNG fails to pay principal or
   interest when due on the Junior Subordinated Debentures, the Trust will not
   have funds to pay distributions on the Trust Preferred Securities or
   amounts due when the Trust Preferred Securities are redeemed or when the
   Trust is liquidated.

 .  The Junior Subordinated Debentures are not secured and are junior in right
   of payment to CNG's senior indebtedness. As of June 30, 2001, CNG had
   approximately $2.7 billion of debt that would have been senior to the
   Junior Subordinated Debentures. CNG expects to incur additional senior debt
   of approximately $900 million in connection with the pending acquisition of
   Louis Dreyfus Natural Gas Corp. The Subordinated Indenture does not limit
   the amount of senior indebtedness that CNG can incur. See ADDITIONAL TERMS
   OF THE JUNIOR SUBORDINATED DEBENTURES in the base prospectus. In addition,
   Louis Dreyfus had approximately $293 million of indebtedness that will be
   assumed by the newly formed subsidiary into which Louis Dreyfus is merging.
   The Junior Subordinated Debentures will be effectively subordinated to that
   debt. See RECENT DEVELOPMENT and UNAUDITED PRO FORMA COMBINED CONDENSED
   FINANCIAL DATA in this prospectus supplement.

 .  CNG's obligations under the Guarantee are not secured and are junior in
   right of payment to all of its other liabilities, except any liabilities
   that expressly rank equal in priority or subordinate to the Guarantee. See
   SUBORDINATION OF THE GUARANTEE in this prospectus supplement.

CNG can defer interest payments on the Junior Subordinated Debentures. This
may affect the market price of the Trust Preferred Securities.

 .  So long as there is no event of default under the Subordinated Indenture,
   CNG may defer interest payments on the Junior Subordinated Debentures, from
   time to time, for an extension period of up to 20 consecutive quarters. At
   the end of an extension period, if all amounts due are paid, CNG could
   start a new extension period of up to 20 consecutive quarters. During any
   extension period, distributions on the Trust Preferred Securities would be
   deferred but would accumulate at an annual rate of 7.8% and you will accrue

                                      S-9


   interest on unpaid distributions at the same rate, compounded quarterly
   (all additional accruals being available to
   the extent permitted by law). No extension period may extend beyond the
   maturity date of the Junior Subordinated Debentures. If CNG exercises this
   extension right, the market price of the Trust Preferred Securities is
   likely to be affected. See SPECIFIC TERMS OF THE TRUST PREFERRED
   SECURITIES-- "Extension of Payment Periods" in this prospectus supplement
   and ADDITIONAL TERMS OF THE JUNIOR SUBORDINATED DEBENTURES--"Option to
   Extend Interest Payment Period" in the base prospectus.

If CNG defers interest payments on the Junior Subordinated Debentures, there
will be United States federal income tax consequences to holders of the Trust
Preferred Securities.

 .  If CNG extends the interest payment period for the Junior Subordinated
   Debentures, you will accrue income as original issue discount, (OID), in
   respect of the deferred distributions on your Trust Preferred Securities.
   As a result, for United States federal income tax purposes you will include
   that OID in gross income before you receive distributions, regardless of
   your regular method of accounting.

 .  If you sell your Trust Preferred Securities before the record date for the
   payment of distributions at the end of
   an extension period, you will not receive the distributions. Instead, the
   accrued distributions will be paid to the holder of record on the record
   date, regardless of who the holder of record may have been on any other
   date during the extension period. Moreover, the accrued OID will be added
   to your adjusted tax basis in the Trust Preferred Securities but might not
   be reflected in the amount you realize on the sale. To the extent the
   amount realized on a sale is less than your adjusted tax basis, you will
   recognize a capital loss for United States federal income tax purposes. The
   deduction of capital losses is subject to limitations.

 .  As a result of CNG's right to extend the interest payment period, the
   market price of the Trust Preferred Securities may be more volatile than
   debt instruments with OID which do not afford the issuer a similar right.
   See MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES --"Interest
   Income and Original Issue Discount" in this prospectus supplement.

The Guarantee is limited to the funds available to the Trust. If CNG defaults
on its obligations under the Junior Subordinated Debentures, the Trust would
not have the funds necessary to make payments on or to redeem the Trust
Preferred Securities.

 .  The Guarantee guarantees the payment when due of distributions on the Trust
   Preferred Securities, to the extent the Trust has funds available to make
   those payments.

 .  The Guarantee also guarantees payment on redemption or on a bankruptcy or
   dissolution of the Trust (except where Junior Subordinated Debentures are
   distributed to the holders) of the liquidation amount and all accrued and
   unpaid distributions on the Trust

                                     S-10


   Preferred Securities to the date of payment or, if less, the amount of the
   assets of the Trust remaining available for distribution. If CNG were to
   default on its payment obligations under the Junior Subordinated
   Debentures, the Trust would lack funds necessary for the payment of
   distributions or amounts payable on liquidation of the Trust or redemption
   of the Trust Preferred Securities. As a result, you would then not be able
   to rely on the Guarantee for payment of those amounts. Instead, the
   Property Trustee would have to enforce the Trust's rights under the Junior
   Subordinated Debentures. Alternatively, you could institute a legal
   proceeding directly against CNG to enforce payment to you of Junior
   Subordinated Debentures in a principal amount equal to the liquidation
   amount of your Trust Preferred Securities and the accrued interest on those
   Junior Subordinated Debentures. See DESCRIPTION OF THE GUARANTEE--
   "General"; DESCRIPTION OF THE TRUST PREFERRED SECURITIES--"Trust
   Enforcement Events" and RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES,
   THE GUARANTEE AND THE JUNIOR SUBORDINATED DEBENTURES HELD BY THE TRUST in
   the base prospectus.

CNG has the right to redeem the Junior Subordinated Debentures if CNG suffers
adverse tax consequences or if the status of the Trust under the Investment
Company Act changes. This redemption would subject you to additional tax.

 .  If there is a Tax Event or an Investment Company Event, as described below,
   CNG will have the right to redeem the Junior Subordinated Debentures, in
   whole, but not in part, at any time within 90 days following the occurrence
   of the Tax Event or an Investment Company Event. That would, in turn, cause
   a mandatory redemption of all of the Trust Preferred Securities and the
   trust common securities at a redemption price as calculated under SPECIFIC
   TERMS OF THE TRUST PREFERRED SECURITIES--"Redemption of Trust Preferred
   Securities" in this prospectus supplement. Under current United States
   federal income tax law, that redemption of your Trust Preferred Securities
   would be a taxable event to you. See SPECIFIC TERMS OF THE TRUST PREFERRED
   SECURITIES--"Right to Redeem upon a Special Event" in this prospectus
   supplement and DESCRIPTION OF THE TRUST PREFERRED SECURITIES--"Mandatory
   Redemption of Trust Preferred Securities" and --"Special Event Redemption"
   in the base prospectus.

CNG may dissolve the Trust at any time. This could have an adverse effect on
the market prices of the Trust Preferred Securities or the Junior Subordinated
Debentures.

 .  At any time, CNG may dissolve the Trust, pay its creditors, if any, and
   distribute the Junior Subordinated Debentures to the holders of the Trust
   Preferred Securities.

 .  There is no assurance as to the market prices for Trust Preferred
   Securities or Junior Subordinated Debentures that may be distributed in
   exchange for Trust Preferred Securities if the Trust is liquidated. The
   Trust Preferred

                                     S-11


   Securities or the Junior Subordinated Debentures may trade at a discount
   from the price that an investor paid to purchase the Trust Preferred
   Securities in this offer.

 .  A distribution of the Junior Subordinated Debentures upon the liquidation of
   the Trust would not be a taxable event to holders of the Trust Preferred
   Securities because the dissolution of the Trust is conditioned upon receipt
   of an opinion from tax counsel that the distribution will not result in the
   recognition of gain or loss for federal income tax purposes by the holders.

 .  As a prospective purchaser of Trust Preferred Securities, you are also
   making an investment decision about the Junior Subordinated Debentures. You
   should carefully review all the information about the Junior Subordinated
   Debentures in this prospectus supplement and in the base prospectus. See
   SPECIFIC TERMS OF THE TRUST PREFERRED SECURITIES--"Distribution of the
   Junior Subordinated Debentures" in this prospectus supplement and
   DESCRIPTION OF THE TRUST PREFERRED SECURITIES--"Distribution of the Junior
   Subordinated Debentures" in the base prospectus.

There is no established trading market for the Trust Preferred Securities.

 .  The Trust Preferred Securities constitute a new issue of securities. They
   have no established trading market. There is no assurance as to the
   liquidity of, or the development and maintenance of trading markets for, the
   Trust Preferred Securities. The Trust will apply to list the Trust Preferred
   Securities on the New York Stock Exchange for trading starting within 30
   days after the Trust Preferred Securities are issued.

There can be no assurance that there will be an active market for the Trust
Preferred Securities.

 .  The underwriters currently plan to make a market in the Trust Preferred
   Securities. However, there can be no assurance that the underwriters will
   engage in those activities or that any active market in the Trust Preferred
   Securities will develop or be maintained.

Except with respect to some mergers involving the Trust, amendments to the
Trust Agreement and amendments to the Guarantee, the holders of the Trust
Preferred Securities have no voting rights.

 .  Holders of Trust Preferred Securities will have no voting rights, except
   voting rights exercisable only in the event of a proposed change in the
   terms of the Trust Preferred Securities or defaults under the Trust
   Agreement and Subordinated Indenture. See DESCRIPTION OF THE TRUST PREFERRED
   SECURITIES--"Voting Rights; Amendment of Trust Agreement" in the base
   prospectus.

Dreyfus Natural Gas Corp. by merging Louis Dreyfus into a newly formed
subsidiary of Dominion. Immediately after this merger, Dominion will contribute
this subsidiary to CNG. Under the terms of the Merger Agreement, each Louis
Dreyfus shareholder will receive $20.00 in cash and a fixed exchange ratio of
0.3226 shares of Dominion common stock for each share of Louis Dreyfus common
stock. The consummation of the merger is subject to the approval of the
stockholders of Louis Dreyfus, approvals under the United States antitrust and
other laws and other customary closing conditions.

USE OF PROCEEDS

  The Trust will invest all of the proceeds from the sale of the Trust
Preferred Securities and the trust common securities toward the purchase of the
Junior Subordinated Debentures from CNG.

  CNG intends to use the net proceeds from the sale of the Junior Subordinated
Debentures in connection with the acquisition of Louis Dreyfus Natural Gas
Corp. and for other general corporate purposes, including the repayment of
debt. This debt may include a portion of CNG's short-term debt, including
commercial paper. At September 30, 2001, the weighted average maturity date of
CNG's approximately $486 million of outstanding commercial paper was
approximately 10 days and the weighted average interest rate was 3.42%.

expense, distributed income of equity investees and fixed charges to income
from continuing operations before cumulative effect of a change in accounting
principle after eliminating the equity in earnings or losses of equity
investees. These earnings are then divided by total fixed charges. Fixed
charges consist of interest charges (without reduction for Allowance for Funds
Used During Construction) on long-term and short-term debt, and the portion of
rentals as is representative of the interest factor.

Louis Dreyfus

In the table below, CNG provides you with the selected consolidated financial

Dominion through a merger with a newly formed, wholly owned subsidiary of
Dominion which will become a subsidiary of CNG. While closing has not yet

SPECIFIC TERMS OF THE TRUST PREFERRED SECURITIES

  Specific terms of the Trust Preferred Securities are summarized below. This
summary is not complete and should be read together with the DESCRIPTION OF THE
TRUST PREFERRED SECURITIES in the base prospectus, where provisions of the
amended trust agreement have been summarized.

  The form of amended trust agreement was filed as an exhibit to the
registration statement, and you should read the Trust Agreement for provisions
that may be important to you. The amended trust agreement will be qualified as
an indenture under the Trust Indenture Act. You should also refer to the Trust
Indenture Act for provisions that apply to the Trust Preferred Securities.

  The amended trust agreement permits the Trust to "reopen" this offering of
Trust Preferred Securities and trust common securities and issue additional
Trust Preferred Securities and trust common securities without the consent of
the holders of the Trust Preferred Securities or the trust common securities.

Distributions

  Distributions on the Trust Preferred Securities will:

 . be payable in U.S. dollars at 7.8% per annum of the liquidation amount,
  including interest payable on overdue distributions, on the basis of a 360-
  day year of twelve 30-day months;

 . be cumulative and payable quarterly in arrears on January 31, April 30, July
  31 and October 31 of each year, commencing January 31, 2002; and

 . originally accrue from, and include, the date they are issued.

  In the event that any distribution date is not a business day, payment will
be made on the next business day, and no interest or other payment will result
from the delay. However, if the deferred payment date is in the next calendar
year, the payment will be made on the last business day of the earlier year.

  A business day is any day that is not a Saturday, a Sunday, a day on which
banks in New York, New York or Richmond, Virginia are authorized or required to
remain closed, or a day on which the Corporate Trust Office of the Property
Trustee or the Subordinated Indenture Trustee is closed for business.

  The record date for distributions will be, for so long as the Trust Preferred
Securities remain in book-entry only form, one business day prior to the
relevant distribution date. In the event the Trust Preferred Securities are not
in book-entry only form, the record date for distributions will be selected by
the Administrative Trustees as provided in the prospectus.

Extension of Payment Periods

  So long as there is no event of default under the Subordinated Indenture, CNG
may defer interest payments on the Junior Subordinated Debentures for an
extension period of up to 20 consecutive quarters. Distributions on the Trust
Preferred Securities would not be paid during any extension period, but would
accrue, with interest on unpaid distributions accruing at an annual rate of
7.8%, compounded

                                      S-19


quarterly (to the extent permitted by law). CNG could not make specified
payments on some of its other securities during an extension period. These
payments are described under SPECIFIC TERMS OF THE JUNIOR SUBORDINATED
DEBENTURES--"Extension of Payment Periods" in this prospectus supplement.

  Before the end of any extension period that is shorter than 20 consecutive
quarters, CNG could further extend the period, so long as the entire extension
period would not exceed 20 consecutive quarters. No payments can be deferred
beyond the maturity date of the Junior Subordinated Debentures. At the end of
any extension period, if all amounts then due on the Junior Subordinated
Debentures, including additional interest on unpaid interest, have been paid,
CNG could elect to begin a new extension period. See ADDITIONAL TERMS OF THE
JUNIOR SUBORDINATED DEBENTURES--"Option to Extend Interest Payment Period" in
the base prospectus.

  CNG has no current intention of exercising its right to defer payments of
interest by extending the interest payment period on the Junior Subordinated
Debentures.

Redemption of Trust Preferred Securities

  The Trust must redeem the Trust Preferred Securities when the Junior
Subordinated Debentures are paid at maturity or if the Junior Subordinated
Debentures are redeemed before they mature. The Junior Subordinated Debentures
will mature on October 31, 2041, and may be redeemed (i) at any time, in whole
but not in part, upon the occurrence of a Special Event at a redemption price
equal to the Special Event Redemption Price, as described below, and (ii) at
any time on or after October 23, 2006, in whole or in part, at a redemption
price equal to the Optional Redemption Price, as described below, plus, in each
case, accrued interest. See "Right to Redeem Upon a Special Event" below for a
description of the term Special Event. In the event that fewer than all of the
outstanding trust securities are to be redeemed, the Trust Preferred Securities
will be redeemed proportionately.

  Upon the repayment of all of the Junior Subordinated Debentures, whether at
maturity or upon redemption, the proceeds from such repayment or payment shall
simultaneously be applied to redeem Trust Preferred Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Junior Subordinated Debentures so repaid or redeemed at the redemption price;
provided that holders of Trust Preferred Securities shall be given not less
than 20 nor more than 60 days notice of such redemption.

  The redemption price shall equal, for each Trust Preferred Security, the
applicable redemption price for a corresponding $25 principal amount of Junior
Subordinated Debentures together with accrued distributions to but excluding
the redemption date.

  The "Special Event Redemption Price" shall be equal to 100% of the principal
amount of such Junior Subordinated Debentures.

  The "Optional Redemption Price" shall be equal to 100% of the principal
amount of such Junior Subordinated Debentures.

                                      S-20


Right to Redeem Upon a Special Event

  CNG will have the right to redeem all, but not fewer than all, of the Junior
Subordinated Debentures, at the Special Event Redemption Price, plus accrued
interest, at any time within 90 days after a Tax Event or an Investment
Company Event (either, a Special Event) happens.

  In the event of redemption of the Junior Subordinated Debentures due to the
occurrence of a Special Event, the Property Trustee will use the proceeds to
redeem the Trust Preferred Securities and trust common securities at a
redemption price equal to the Special Event Redemption Price for a
corresponding $25 principal amount of Junior Subordinated Debentures plus any
unpaid distributions to but excluding the date of redemption.

  A Tax Event means that the Administrative Trustees have received an opinion
of independent tax counsel experienced in those matters to the effect that, as
a result of any amendment to, change or announced proposed change in:

 . the laws or regulations of the United States or any of its political
  subdivisions or taxing authorities, or

 . any official administrative pronouncement, action or judicial decision
  interpreting or applying those laws or regulations,

which amendment or change becomes effective or proposed change, pronouncement,
action or decision is announced on or after the date the Trust Preferred
Securities are issued and sold, there is more than an insubstantial risk that:

 . the Trust is or within 90 days would be subject to U.S. federal income tax
  with respect to income accrued or received on the Junior Subordinated
  Debentures,

 . interest payable to the Trust on the Junior Subordinated Debenture is not or
  within 90 days would not be deductible, in whole or in part, by CNG for U.S.
  federal income tax purposes, or

 . the Trust is or within 90 days would be subject to a material amount of
  other taxes, duties or other governmental charges.

  Investment Company Event means that the Administrative Trustees have
received an opinion of a nationally recognized independent counsel to the
effect that, as a result of an amendment to or change in the Investment
Company Act or regulations thereunder on or after the date the Trust Preferred
Securities are issued and sold, there is more than an insubstantial risk that
the Trust is or will be considered an investment company and be required to be
registered under the Investment Company Act.

Liquidation

  The amount payable on the Trust Preferred Securities in the event of any
liquidation of the Trust is $25 per Trust Preferred Security plus accumulated
and unpaid distributions, which may be in the form of a distribution of Junior
Subordinated Debentures. See "Distribution of Junior Subordinated Debentures"
below and DESCRIPTION OF THE TRUST PREFERRED SECURITIES --  "Liquidation
Distribution Upon Dissolution" in the base prospectus.

Distribution of the Junior Subordinated Debentures

  In addition to the events that would cause a dissolution of the Trust as
described under

                                     S-21


DESCRIPTION OF THE TRUST PREFERRED SECURITIES --"Liquidation Distribution Upon
Dissolution" in the base prospectus and subject to the condition described
below, at any time, CNG may:

 . dissolve the Trust; and

 . distribute Junior Subordinated Debentures to the holders of the Trust
  Preferred Securities.

  The right to dissolve the Trust and distribute the Junior Subordinated
Debentures will be conditioned on CNG's receipt of an opinion rendered by an
independent tax counsel that the distribution would not result in the
recognition of gain or loss for federal income tax purposes by the holders.
After dissolution and distribution of the Junior Subordinated Debentures, the
Trust Preferred Securities and the trust common securities will no longer be
outstanding. Certificates representing Trust Preferred Securities will then
represent Junior Subordinated Debentures that:

 . have a principal amount equal to the liquidation amount of the Trust
  Preferred Securities; and

 . bear accrued and unpaid interest equal to any accrued and unpaid
  distributions on the Trust Preferred Securities.

  If CNG distributes Junior Subordinated Debentures to holders of Trust
Preferred Securities in a dissolution of the Trust, those Junior Subordinated
Debentures will be issued in denominations of $25 and integral multiples of $25
and will initially be issued in the form of one or more global securities. DTC,
or any successor depositary for the Trust Preferred Securities, will act as
depositary for the Junior Subordinated Debentures. It is anticipated that the
depositary arrangements for the Junior Subordinated Debentures would be
substantially identical to those in effect for the Trust Preferred Securities.
See BOOK-ENTRY PROCEDURES AND SETTLEMENT in this prospectus supplement. There
can be no assurances as to the market price of any Junior Subordinated
Debentures that may be distributed to the holders of Trust Preferred
Securities.

Book-Entry Securities

  The Trust Preferred Securities will trade through DTC. The Trust Preferred
Securities will be represented by a global certificate and registered in the
name of Cede & Co., DTC's nominee. See BOOK-ENTRY PROCEDURES AND SETTLEMENT in
this prospectus supplement.

Information Concerning the Property Trustee

  Bank One Trust Company, National Association is the Property Trustee. It is
also the Guarantee Trustee and the Subordinated Indenture Trustee. CNG and
certain of its affiliates maintain deposit accounts and banking relationships
with Bank One, N.A., an affiliate of Bank One Trust Company, National
Association. Bank One Trust Company, National Association also serves as
trustee under other indentures pursuant to which CNG's securities and
securities of certain of its affiliates are outstanding.

Information Concerning the Delaware Trustee

  Bank One Delaware, Inc. is the Delaware Trustee. It is an affiliate of Bank
One Trust Company, National Association which

                                      S-22


serves as Property Trustee and in the other capacities described above under
"Information Concerning the Property Trustee."

SPECIFIC TERMS OF THE JUNIOR SUBORDINATED DEBENTURES

  Specific terms of the Junior Subordinated Debentures are summarized below.
This summary is not complete and should be read together with the DESCRIPTION
OF DEBT SECURITIES and ADDITIONAL TERMS OF THE JUNIOR SUBORDINATED DEBENTURES
in the base prospectus, where provisions of the Subordinated Indenture have
been summarized.

  The Subordinated Indenture under which the Junior Subordinated Debentures
will be issued was filed as an exhibit to the registration statement and the
supplemental indenture under which the Junior Subordinated Debentures will be
issued will be filed as an exhibit to a current report on Form 8-K, and are
incorporated by reference herein, and you should read these documents for
provisions that may be important to you. The Subordinated Indenture is
qualified as an indenture under the Trust Indenture Act. You should also refer
to the Trust Indenture Act for provisions that apply to the Junior Subordinated
Debentures.

  The Subordinated Indenture permits CNG to "reopen" this series of Junior
Subordinated Debentures and issue additional Junior Subordinated Debentures of
this series without the consent of the holders of Junior Subordinated
Debentures.

  The Junior Subordinated Debentures will mature on October 31, 2041.

Interest

  Interest on the Junior Subordinated Debentures will:

 . be payable in U.S. dollars at 7.8% per annum, including interest payable on
  overdue interest, on the basis of a 360-day year of twelve 30-day months;

 . be cumulative and payable quarterly in arrears on January 31, April 30, July
  31 and October 31 of each year, beginning January 31, 2002; and

 . originally accrue from, and include, the date they are issued.

  If any payment date is not a business day, payment will be made on the next
following business day, and no interest or other payment will result from the
delay. However, if the deferred payment date is in the next calendar year, the
payment will be made on the last business day of the earlier year.

  For so long as the Trust Preferred Securities or Junior Subordinated
Debentures distributed to holders of Trust Preferred Securities remain in book-
entry only form, the record date for interest will be one business day prior to
the scheduled distribution or interest payment date. For any of these Junior
Subordinated Debentures not in book-entry only form, the record date for
distributions will be the fifteenth day before the scheduled distribution or
interest payment date, whether or not it is a business day.

Extension of Payment Periods

  So long as there is no event of default under the Subordinated Indenture, CNG
may defer interest payments on the Junior Subordinated Debentures for an
extension

                                      S-23


period of up to 20 consecutive quarters; provided, however, that no such
extension period may extend beyond the maturity of the Junior Subordinated
Debentures. During this period, the interest on the Junior Subordinated
Debentures will still accrue at a per annum rate of 7.8%. In addition, interest
on the unpaid interest will accrue at an annual rate of 7.8%, compounded
quarterly, to the extent permitted by law. Distributions on the Trust Preferred
Securities would not be paid during any extension period with respect to the
Junior Subordinated Debentures, but would accumulate at the per annum rate of
7.8%. In addition, interest on unpaid distributions will accrue at an annual
rate of 7.8%, compounded quarterly, to the extent permitted by law. When we
refer to any payment of interest, interest includes such additional interest
and any interest payable as described in the second bullet point under
ADDITIONAL TERMS OF THE JUNIOR SUBORDINATED DEBENTURES--"Additional Covenants
Applicable to Junior Subordinated Debentures" in the base prospectus.

  Before the end of any extension period that is shorter than 20 consecutive
quarters, CNG could further extend the period, so long as the entire extension
period would not exceed 20 consecutive quarters. No payments can be deferred
beyond the maturity date of the Junior Subordinated Debentures. At the end of
any extension period, if all amounts then due on the Junior Subordinated
Debentures, including additional interest on unpaid interest, have been paid,
CNG could elect to begin a new extension period.

  If CNG defers payment on the Junior Subordinated Debentures, CNG may not:

 . declare or pay any dividend or distribution on its capital stock, other than
  dividends paid in shares of its common stock;

 . redeem, purchase, acquire or make a liquidation payment with respect to, any
  of its capital stock;

 . make any payment of principal or of interest or premiums, if any, on, or
  repay or repurchase or redeem any, indebtedness that is equal in right of
  payment with, or subordinated to, the Junior Subordinated Debentures; or

 . make any guarantee payments with respect to any of the above.

See ADDITIONAL TERMS OF THE JUNIOR SUBORDINATED DEBENTURES--"Option to Extend
Interest Payment Period" in the base prospectus.

  Any extension of the payment period for interest on the Junior Subordinated
Debentures, or on any other securities issued under the Subordinated Indenture
or on any similar securities, will apply to all securities of the same type.
Those extensions will also apply to distributions on Trust Preferred Securities
and trust common securities and all other securities with similar rankings as
Trust Preferred Securities and trust common securities. CNG will give the Trust
and the Subordinated Indenture Trustee notice of its election of an extension
period before the earlier of:

 . one business day before the record date for the scheduled distribution; and

 . the date it is required to give notice of an extension period to the New York
  Stock Exchange.

                                      S-24


  CNG will cause the Trust to send notice of that election to the holders of
Trust Preferred Securities.

Redemption

  The Junior Subordinated Debentures may be redeemed (i) at any time, in whole
but not in part, within 90 days after the occurrence of a Special Event at a
redemption price equal to the Special Event Redemption Price and (ii) at any
time on or after October 23, 2006, in whole or in part, at a redemption price
equal to the Optional Redemption Price, plus, in each case, accrued interest.

  For the definitions of Tax Event and Investment Company Event, see SPECIFIC
TERMS OF THE TRUST PREFERRED SECURITIES--"Right to Redeem Upon a Special Event"
in this prospectus supplement. For the definitions of Special Event Redemption
Price and Optional Redemption Price, see SPECIFIC TERMS OF THE TRUST PREFERRED
SECURITIES--"Redemption of the Trust Preferred Securities" in this prospectus
supplement.

SUBORDINATION OF THE GUARANTEE

  CNG's obligations under the Guarantee will be its unsecured obligations.
Those obligations will rank:

  .  subordinate and junior in right of payment to all of its other
     liabilities, other than obligations or liabilities that rank equal in
     priority or subordinate by their terms;

  .  equal in priority with the Junior Subordinated Debentures that it may
     issue and similar guarantees; and

  .  senior to any preferred and common stock.

  CNG currently has no Junior Subordinated Debentures outstanding that rank
equal in priority with the Guarantee. CNG has no preferred stock outstanding at
this time. CNG has common stock outstanding that will rank junior to the
Guarantee. All of CNG's outstanding common stock is owned by Dominion.

  The Guarantee will be a guarantee of payment and not of collection. This
means that the guaranteed party may institute a legal proceeding directly
against CNG, as guarantor, to enforce its rights under the Guarantee without
first instituting a legal proceeding against any other person or entity.

  The terms of the Trust Preferred Securities will provide that each holder of
the Trust Preferred Securities, by accepting those Trust Preferred Securities,
agrees to the subordination provisions and other terms of the Guarantee.

BOOK-ENTRY PROCEDURES AND SETTLEMENT

  Upon issuance, all book-entry securities will be represented by one or more
fully registered global certificates. Each global security will be deposited
with DTC or its custodian and will be registered in the name of DTC or a
nominee of DTC. DTC will thus be the only registered holder of these
securities.

  The following is based on information furnished to us by DTC:

  DTC is a limited-purpose trust company organized under the laws of the State
of New York, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the

                                      S-25


Uniform Commercial Code and a "clearing agency" registered under the provisions
of Section 17A of the Exchange Act. DTC was created to hold securities of its
participants (Participants) and to facilitate the clearance and settlement of
securities transactions among its Participants in these securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. DTC's
Participants include securities brokers and dealers (including the
underwriters), banks, trust companies, clearing corporations and certain other
organizations, some of whom (and/or their representatives) own DTC. Persons who
are not Participants may beneficially own securities held by DTC only through
Participants.

  DTC is owned by a number of its Direct Participants and by the New York Stock
Exchange, Inc., the American Stock Exchange LLC and the National Association of
Securities Dealers, Inc. Access to DTC's system is also available to others
including securities brokers and dealers, banks and trust companies that clear
through or maintain a custodial relationship with a Direct Participant, either
directly or indirectly (Indirect Participants). The rules applicable to DTC and
its Participants are on file with the SEC.

  Purchases of securities within the DTC system must be made by or through
Direct Participants, which will receive a credit for the securities on DTC's
records. The ownership interest of each actual purchaser of securities
(Beneficial Owner) is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial owners will not receive written confirmation
from DTC of their purchases, but Beneficial Owners are expected to receive
written confirmations providing details of the transactions, as well as
periodic statements of their holdings, from the Direct or Indirect Participants
through which the beneficial Owners purchased securities. Transfers of
ownership interests in the securities are to be accomplished by entries made on
the books of Participants acting on behalf of Beneficial Owners. Beneficial
Owners will not receive certificates representing their ownership interests in
securities, unless use of the book-entry system for the securities is
discontinued.

  DTC has no knowledge of the actual Beneficial Owners of the securities. DTC's
records reflect only the identity of the Direct Participants to whose accounts
the securities are credited, which may or may not be the Beneficial Owners. The
Participants will remain responsible for keeping account of their holdings on
behalf of their customers.

  Conveyance of notices and other communications by DTC to Direct Participants,
by Direct Participants to Indirect Participants, and by Direct Participants and
Indirect Participants to Beneficial Owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.

  Although voting with respect to the Trust Preferred Securities is limited, in
those cases where a vote is required, neither DTC nor Cede and Co. will itself
consent or vote. Under its usual procedures, DTC would mail an Omnibus Proxy to
CNG as soon as possible after the record date. The Omnibus Proxy assigns Cede &
Co.'s consenting or voting rights to those Direct Participants to whose
accounts the securities are credited on the record date

                                      S-26


(identified in a listing attached to the Omnibus Proxy).

  Payments on the Trust Preferred Securities will be made to DTC in immediately
available funds. DTC's practice is to credit Direct Participants' accounts on
the relevant payment date in accordance with their respective holdings shown on
DTC's records unless DTC has reason to believe that it will not receive
payments on the relevant payment date. Payments by Participants to Beneficial
Owners will be governed by standing instructions and customary practices, as is
the case with securities held for the account of customers in bearer form or
registered in "street name," and will be the responsibility of the Participant
and not our responsibility or the responsibility of DTC, subject to any
statutory or regulatory requirements as may be in effect from time to time.
Payment to DTC is our responsibility, disbursement of the payments to Direct
Participants is the responsibility of DTC, and disbursement of the payments to
the Beneficial Owners is the responsibility of Direct and Indirect
Participants.

  Except as provided in this prospectus supplement, a Beneficial Owner of
securities will not be entitled to receive physical delivery of securities.
Accordingly, each Beneficial Owner must rely on the procedures of DTC to
exercise any rights under the Trust Preferred Securities. The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of securities in definitive form. These laws may impair the ability to
transfer beneficial interests in a global security.

  DTC may discontinue providing its services as securities depositary with
respect to the Trust Preferred Securities at any time by giving reasonable
notice to CNG. Under those circumstances, if a successor securities depositary
is not obtained, securities certificates will be printed and delivered to the
holders of record. Additionally, we may decide to discontinue use of the system
of book-entry transfers through DTC (or a successor depositary) with respect to
the Trust Preferred Securities. In that event, certificates for the Trust
Preferred Securities will be printed and delivered to the holders of record.

  We have no responsibility for the performance by DTC or its Participants of
their respective obligations as described in this prospectus supplement or
under the rules and procedures governing their respective operations.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

General

  In this section, we summarize certain of the material United States federal
income tax consequences of purchasing, owning and selling the Trust Preferred
Securities. The statements of law and legal conclusions set forth in this
summary represent the opinion of McGuireWoods LLP, special tax counsel to CNG
and the Trust. Except where stated otherwise, this summary deals only with
Trust Preferred Securities held as capital assets (as defined in the Internal
Revenue Code of 1986, as amended (the "Code")) by a U.S. Holder (as defined
below) who purchases the Trust Preferred Securities at their original offering
price when the Trust originally issues them.

  We do not address all of the tax consequences that may be relevant to a U.S.
Holder. We also do not address, except as stated below, any of the tax
consequences

                                      S-27


to holders that may be subject to special tax treatment including banks,
thrift institutions, real estate investment trusts, personal holding
companies, tax-exempt organizations, regulated investment companies, insurance
companies, and brokers and dealers in securities or currencies. Further, we do
not address:

 . the United States federal income tax consequences to shareholders in, or
  partners or beneficiaries of, an entity that is a holder of the Trust
  Preferred Securities;

 . the United States federal estate and gift or alternative minimum tax
  consequences of the purchase, ownership or sale of the Trust Preferred
  Securities;

 . persons who hold the Trust Preferred Securities in a "straddle" or as part
  of a "hedging," "conversion" or "constructive sale" transaction or whose
  "functional currency" is not the United States dollar; or

 . any state, local or foreign tax consequences of the purchase, ownership and
  sale of Trust Preferred Securities.

  You should consult your tax advisor regarding the tax consequences of
purchasing, owning and selling the Trust Preferred Securities in light of your
circumstances.

  A "U. S. Holder" is a Trust Preferred Securities holder who or which is:

 . a citizen or resident of the United States;

 . a corporation, or other entity treated as a corporation for United States
  Federal income tax purposes, created or organized in or under the laws of
  the United States, any state thereof or the District of Columbia;

 . an estate if its income is subject to United States federal income taxation
  regardless of its source; or

 . a trust if (1) a United States court can exercise primary supervision over
  its administration and (2) one or more United States persons have the
  authority to control all of its substantial decisions.

  This summary is based on the Code, Treasury regulations (proposed and final)
issued under the Code, and administrative and judicial interpretation thereof,
all as they currently exist as of the date of this prospectus supplement.
These income tax laws and regulations, however, may change at any time,
possibly on a retroactive basis. Any such changes may affect this summary.

Classification of the Junior Subordinated Debentures

  McGuireWoods LLP will render its opinion to the effect that the Junior
Subordinated Debentures will be classified under current law for United States
federal income tax purposes as CNG's indebtedness, and, by acceptance of a
Trust Preferred Security, each holder covenants to treat the Junior
Subordinated Debentures as indebtedness and the Trust Preferred Securities as
evidence of an indirect beneficial ownership interest in the Junior
Subordinated Debentures. No assurance can be given, however, that the Internal
Revenue Service will not challenge this position or, if challenged, that such
a challenge would not be successful. The remainder of this discussion assumes
that the Junior Subordinated Debentures will be

                                     S-28


classified as indebtedness of CNG for United States federal income tax
purposes.

Classification of the Trust

  In connection with the issuance of the Trust Preferred Securities,
McGuireWoods LLP will render a legal opinion generally to the effect that,
under current law and assuming full compliance with the terms of the trust
agreement, the indenture, and certain other documents, and based on certain
facts and assumptions described in the opinion, the Trust will be classified
for United States federal income tax purposes as a grantor trust and will not
be subject to tax as a corporation. Accordingly, for United States federal
income tax purposes, you will generally be treated as the owner of an undivided
beneficial interest in the assets of the Trust, including the Junior
Subordinated Debentures. You will be required to include in ordinary income for
United States federal income tax purposes your allocable share of interest (or
"OID", if any) paid or accrued on the Junior Subordinated Debentures.

Interest Income and Original Issue Discount

  Generally, stated interest on the Junior Subordinated Debentures will be
taxable as ordinary income at the time the interest is paid or accrued
(depending on your method of tax accounting) unless the Junior Subordinated
Debentures are issued with original issue discount or OID.

  Under the Treasury regulations relating to OID, a debt instrument will be
deemed to be issued with OID if there is more than a "remote" contingency that
periodic stated interest payments due on the instrument will not be timely
paid. Because the exercise by CNG of its option to defer payments of stated
interest on the Junior Subordinated Debentures would prevent it from:

 . declaring dividends, or engaging in certain other capital transactions, with
  respect to its capital stock, or

 . making any payment on any debt securities issued by it that rank equal with
  or junior to the Junior Subordinated Debentures,

CNG believes that the likelihood of it exercising the option is "remote" within
the meaning of the Treasury regulations.

  As a result, CNG intends to take the position, based on the advice of its tax
counsel, that the Junior Subordinated Debentures will not be deemed to be
issued with OID. Based on this position, stated interest payments on the Junior
Subordinated Debentures will be includible in your ordinary income at the time
that such payments are received or accrued in accordance with your regular
method of accounting. Because the Internal Revenue Service has not yet
addressed the Treasury regulations in any published rulings or other
interpretations, it is possible that the Internal Revenue Service could take a
position contrary to the position taken by CNG . In that event, the Internal
Revenue Service may, for example, require you to include interest on the Junior
Subordinated Debentures in your taxable income as it accrues rather than when
you receive payment even though you use the cash method of accounting for
federal income tax purposes.

Exercise of Deferral Options

  Under Treasury regulations, if CNG were to exercise its option to defer the
payment of interest on the Junior Subordinated

                                      S-29


Debentures, the Junior Subordinated Debentures would be treated as redeemed and
reissued for OID purposes and the sum of the remaining interest payments on the
Junior Subordinated Debentures would be treated as OID, which you would be
required to accrue and include in taxable income on an economic accrual basis
(regardless of your method of accounting for income tax purposes) over the
remaining term of the Junior Subordinated Debentures (including any period of
interest deferral), without regard to the timing of payments under the Junior
Subordinated Debentures. The amount of interest income includible in your
taxable income would be determined on the basis of a constant yield method over
the remaining term of the Junior Subordinated Debentures and the actual receipt
of future payments of stated interest on the Junior Subordinated Debentures
would no longer be separately reported as taxable income. The total amount of
OID that would accrue during the deferred interest payment period would be
approximately equal to the amount of the cash payment due at the end of such
period. Any OID included in income would increase your adjusted tax basis in
your Trust Preferred Securities, and your actual receipt of cash interest
payments would reduce your basis in the Trust Preferred Securities.

Corporate U.S. Holders

  Corporate U.S. holders of the Trust Preferred Securities will not be entitled
to a dividends-received deduction for any income from the Trust Preferred
Securities.

Sales of Trust Preferred Securities

  If you sell your Trust Preferred Securities, you will recognize gain or loss
in an amount equal to the difference between your adjusted tax basis in the
Trust Preferred Securities and the amount realized from the sale (generally,
your selling price less any amount received in respect of accrued but unpaid
interest not previously included in your income). Your adjusted tax basis in
the Trust Preferred Securities generally will equal:

 . the initial purchase price that you paid for the Trust Preferred Securities
  plus

 . any accrued and unpaid distributions that you were required to treat as OID
  less any cash distributions received in respect of accrued OID.

  Gain or loss on the sale of Trust Preferred Securities generally will be
capital gain or loss.

  The Trust Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest (or OID if the Junior
Subordinated Debentures are treated as having been issued or reissued with OID)
relating to the underlying Junior Subordinated Debentures. If you dispose of
your Trust Preferred Securities, you will be required to include in ordinary
income for United States federal income tax purposes any portion of the amount
realized that is attributable to accrued but unpaid interest (including OID, if
any) through the date of sale. This income inclusion will increase your
adjusted tax basis in the Trust Preferred Securities but may not be reflected
in the sale price. To the extent the sale price is less than your adjusted tax
basis, you will recognize a capital loss. Subject to certain limited
exceptions, capital losses cannot be applied to offset ordinary income for
United States federal income tax purposes.

                                      S-30


Receipt of Junior Subordinated Debentures or Cash Upon Liquidation of the Trust

  If CNG dissolves the Trust and causes the Trust to distribute the Junior
Subordinated Debentures on a proportionate basis to you, you will not be
subject to tax. Rather, you would have an adjusted tax basis in the Junior
Subordinated Debentures received in the liquidation equal to the adjusted tax
basis in your Trust Preferred Securities surrendered for the Junior
Subordinated Debentures. Your holding period for the Junior Subordinated
Debentures would include the period during which you had held the Trust
Preferred Securities. If, however, the trust is classified, for United States
federal income tax purposes, as an association that is subject to tax as a
corporation at the time of the liquidation, the distribution of the Junior
Subordinated Debentures would constitute a taxable event to you and you would
acquire a new holding period in the Junior Subordinated Debentures received.

  If the Junior Subordinated Debentures are redeemed for cash and the proceeds
of the redemption are distributed to you in redemption of your Trust Preferred
Securities, the redemption would be treated as a sale of the Trust Preferred
Securities, in which gain or loss would be recognized, as described immediately
above.

Possible Tax Legislation

  Certain tax law changes have been proposed from time to time which could
affect the deductibility of interest paid on instruments similar to the Junior
Subordinated Debentures. None of these proposals have become law. There can be
no assurance however that legislation affecting CNG's ability to deduct
interest paid on the Junior Subordinated Debentures will not be enacted in the
future or that any such legislation would not be effective retroactively. Any
such legislation could give rise to a Tax Event and result in the early
redemption of the Trust Preferred Securities.

Information Reporting and Back-Up Withholding

  Generally, income on the Trust Preferred Securities will be reported to you
on an Internal Revenue Service Form 1099, which should be mailed to you by
January 31 following each calendar year. If you fail to supply your correct
taxpayer identification number or under-report your tax liability, the Internal
Revenue Service may require the property trustee or its agent to withhold
federal income tax from each interest payment. You will be permitted to credit
any withheld tax against your federal income tax liability.

ERISA CONSIDERATIONS

  ERISA and the Internal Revenue Code impose requirements on Plans and Plan
fiduciaries. The term "Plan" means an employee benefit plan, as defined in
Section 3(3) of ERISA, that is subject to Title I of ERISA; a plan, as defined
in Section 4975(e)(1) of the Internal Revenue Code, that is subject to Section
4975 of the Internal Revenue Code, including individual retirement accounts or
Keogh plans; and an entity whose underlying assets include plan assets by
reason of a plan's investment in that entity, including insurance company
general accounts. A Plan fiduciary considering an investment in the Trust
Preferred Securities should determine, among other factors, whether that
investment is permitted under the

                                      S-31


governing Plan instruments, is appropriate for the Plan in view of its overall
investment policy and the composition and diversification of its portfolio and
is prudent considering the factors discussed in this prospectus supplement and
the attached prospectus.

  ERISA and the Internal Revenue Code prohibit various transactions involving
the assets of a Plan and persons referred to as parties in interest under ERISA
or disqualified persons under the Internal Revenue Code. A prohibited
transaction could subject disqualified persons to excise taxes and impose other
liabilities on Plan fiduciaries, unless exemptive relief is available under an
applicable statutory or administrative exemption. Such administrative
exemptions include prohibited transaction class exemption ("PTCE") 96-23 (for
certain transactions effected by in-house asset managers), PTCE 95-60 (for
certain transactions involving insurance company general accounts),
PTCE 91-38 (for certain transactions involving bank collective investment
funds), PTCE 90-1 (for certain transactions involving insurance company pooled
separate accounts), and PTCE 84-14 (for certain transactions determined by
independent qualified asset managers). A Plan fiduciary considering an
investment in the Trust Preferred Securities should consider whether that
investment might constitute a prohibited transaction under ERISA or the
Internal Revenue Code, and whether exemptive relief is available.

  A number of employee benefit plans, such as foreign plans, governmental
plans, as defined in Section 3(32) of ERISA, and certain church plans, as
defined in Section 3(33) of ERISA, are not subject to the restrictions of
ERISA. As a result, assets of these plans may be invested in the Trust
Preferred Securities without regard to the ERISA restrictions, subject to the
provisions of any other applicable federal or state law. You should note,
however, that any governmental plan or church plan that is qualified and exempt
from taxation under Sections 401(a) and 501(a) of the Internal Revenue Code is
subject to the prohibited transaction rules set forth in Section 503 of the
Internal Revenue Code.

Prohibited Transaction Considerations

  Treatment of Trust Assets as Plan Assets. A transaction involving the
operation of the Trust might constitute a prohibited transaction under ERISA
and the Internal Revenue Code if assets of the Trust were deemed to be assets
of an investing Plan. The United States Department of Labor ("DOL") has issued
regulations, called the plan asset regulations, addressing whether the assets
of a Plan would include the assets of an entity in which the Plan has invested
for purposes of the fiduciary responsibility provisions of ERISA and the
prohibited transaction provisions of ERISA and the Internal Revenue Code. In
general, under the plan asset regulations, when a Plan acquires an equity
interest in an entity such as the Trust, the assets of the Plan include both
the equity interest and an undivided interest in each of the underlying assets
of the entity unless the exceptions set forth in the regulations apply. In
general, an equity interest is defined under the plan asset regulations as any
interest in an entity, other than an instrument that is treated as indebtedness
under applicable local law and has no substantial equity features, and includes
a beneficial interest in a trust.

  If the assets of the Trust are deemed to be the assets of an investing Plan,
any person who has discretionary authority or

                                      S-32


control with respect to the Trust assets, and any person who provides
investment advice for a fee with respect to Trust assets, will be a fiduciary
of the investing Plan. This fiduciary status would increase the scope of
activities that would constitute prohibited transactions under ERISA and the
Internal Revenue Code.

  Exception for Insignificant Participation by Benefit Plan Investors. The
plan asset regulations provide that the assets of an entity such as the Trust
will not be deemed to be the assets of an investing Plan if equity
participation in the entity by benefit plan investors, such as employee
benefit plans or individual retirement accounts, is not significant. An equity
participation in an entity is not deemed to be significant if benefit plan
investors hold less than 25% of the value of each class of equity interests in
that entity. In calculating the value of a class of equity interests, the
value of any equity interests held by CNG, the Trustee or any of their
affiliates must be excluded. We cannot assure you that benefit plan investors
will hold less than 25% of the value of each class of equity interests in the
Trust.

  Exception for Publicly Offered Securities. The plan asset regulations
provide that the issuer of a publicly-offered security acquired by a Plan will
not be deemed to hold Plan assets solely because of that acquisition. A
publicly-offered security is a security that is freely transferable, part of a
class of securities that is owned by 100 or more investors independent of the
issuer and of one another and either:

 . part of a class of securities registered under the Exchange Act; or

 . sold to the Plan as part of an offering of securities to the public under
   the Securities Act; provided, however, that the class of securities of
   which the security is a part must be registered under the Exchange Act
   within 120 days, or later if allowed by the SEC, after the end of the
   fiscal year of the issuer during which the offering of the securities to
   the public occurred.

  The underwriters expect that the Trust Preferred Securities will qualify as
publicly offered securities under the plan asset regulations. We cannot assure
you that the Trust Preferred Securities will be held by 100 or more
independent investors, however, and no monitoring or other measures will be
taken to insure that this requirement of the publicly offered security
exception will be satisfied. If the Trust Preferred Securities do not qualify
as publicly offered securities under the plan asset regulations, the assets of
the Trust may be deemed the assets of any Plan that invests in the Trust
Preferred Securities. In that event, transactions involving the Trust and
either parties in interest or disqualified persons with respect to an
investing Plan might be prohibited under ERISA or the Internal Revenue Code
and could subject disqualified persons to excise taxes and impose other
liabilities on Plan fiduciaries, unless exemptive relief is available under an
applicable statutory or administrative exemption.

  We suggest that Plan fiduciaries or other persons considering an investment
in the Trust Preferred Securities on behalf of or with the assets of a Plan
consult their own counsel regarding the consequences to the Plan of that
investment, including the consequence to the Plan if the assets of the Trust
were to become subject to the fiduciary and prohibited transaction rules of
ERISA and the Internal Revenue Code.

                                     S-33


Additional Considerations for Insurance Company General Accounts

  In John Hancock Mut. Life Ins. Co. v. Harris Trust and Sav. Bank, 510 U.S. 86
(1993), the United States Supreme Court held that, under some circumstances,
assets held in an insurance company's general account may be deemed to be
assets of Plans that were issued policies supported by that general account.

  The Small Business Job Protection Act of 1996 added a new section of ERISA
relating to the status of the assets of insurance company general accounts
under ERISA and the Internal Revenue Code. This new section provides that
assets underlying general account policies issued before December 31, 1998 will
not be considered assets of a Plan to the extent the criteria set forth in DOL
regulations are satisfied. This new section also requires the DOL to issue
regulations establishing those criteria. On January 5, 2000, the DOL issued
final regulations, called the general account regulations, for this purpose.
These regulations took effect July 5, 2001. The general account regulations
provide that, when a Plan acquires a policy issued by an insurance company on
or before December 31, 1998 which is supported by assets of the insurance
company's general account, the assets of the Plan will include the policy but
not the underlying assets of the general account to the extent the requirements
set forth in the general account regulations are satisfied. The general account
regulations do not apply to any general account policies issued after December
31, 1998.

  We suggest that Plan fiduciaries or other persons considering an investment
in the Trust Preferred Securities on behalf of an insurance company general
account consult their own counsel regarding the effect of the John Hancock
decision and the general account regulations on that investment.

UNDERWRITING

    Under the terms and subject to the conditions contained in an underwriting
agreement, dated the date of this prospectus supplement (the Underwriting
Agreement), each of the underwriters named below has agreed to purchase, and
the Trust has agreed to sell to each of the underwriters, severally, the number

  Salomon Smith Barney Inc. and First Union Securities, Inc. are acting as
Representatives of the underwriters in connection with the offering of the
Trust Preferred Securities. First Union Securities, Inc. is an indirect,
wholly-owned subsidiary of Wachovia Corporation. Wachovia Corporation conducts
its investment banking, institutional, and capital markets businesses through
its various bank, broker-dealer and nonbank subsidiaries under the trade name
of Wachovia Securities. Any references to Wachovia Securities in this
Prospectus, however, do not include Wachovia Securities, Inc., member NASD/SIPC
and a separate broker-dealer subsidiary of Wachovia Corporation and sister
affiliate of the Underwriter which may or may not be participating as a selling
dealer in the distribution of the Trust Preferred Securities.

  The Underwriting Agreement provides that the obligations of the several
underwriters to purchase and pay for the Trust Preferred Securities are subject
to, among other things, the approval of certain legal matters by their counsel
and certain other conditions. The underwriters are obligated to take and pay
for all of the Trust Preferred Securities if any are taken. In the event of
default by an underwriter, the Underwriting Agreement provides that, in some
circumstances, the purchase commitments of the nondefaulting underwriters may
be increased or the Underwriting Agreement may be terminated.

  The underwriters initially propose to offer part of the Trust Preferred
Securities directly to the public at the initial public offering price set
forth on the cover page hereof and part to certain dealers at a price that
represents a concession not in excess of $0.50 per Trust Preferred Security.
Any underwriter may allow, and any dealer may reallow, a concession to certain
other dealers not to exceed $0.45 per Trust Preferred Security. After the
initial offering of the Trust Preferred Securities, the offering price
concession and other selling terms may from time to time be varied by the
underwriters.

  Because the proceeds of the sale of the Trust Preferred Securities will
ultimately be used to purchase the Junior Subordinated Debentures of CNG, the
Underwriting Agreement provides that CNG will pay to the underwriters as
compensation for their services $0.7875 per Trust Preferred Security, or
$6,300,000 in the aggregate. CNG will also pay other expenses of the offering,
which it expects to be approximately $300,000.

  CNG and the Trust have agreed that, without the prior written consent of the

                                      S-35


representatives, on behalf of the underwriters, they will not, during the
period ending 30 days after the date of this prospectus supplement and the
delivery of the Trust Preferred Securities, directly or indirectly, publicly
issue, sell, offer or contract to sell, in the market in which the Trust
Preferred Securities are being offered and sold, any securities of CNG or any
of its subsidiaries which are of the same class as the Trust Preferred
Securities.

  Prior to this offering, there has been no market for the Trust Preferred
Securities. The Trust plans to list the Trust Preferred Securities on the New
York Stock Exchange, and trading of the Trust Preferred Securities is expected
to begin within a 30 day period after the Trust Preferred Securities are first
issued. In order to meet all of the requirements for listing the Trust
Preferred Securities on the New York Stock Exchange, the underwriters have
agreed to sell in lots of 100 or more the Trust Preferred Securities to a
minimum of 400 beneficial holders. The underwriters have advised CNG that they
intend to make a market in the Trust Preferred Securities but are not obligated
to do so and may discontinue market making at any time without notice. No
assurance can be given as to the liquidity of the trading market for the Trust
Preferred Securities.

  It is expected that delivery of the Trust Preferred Securities will be made
against payment on or about October 23, 2001, which is the fifth business day
following the date of this prospectus supplement. This settlement cycle is
referred to as "T+5'. Purchasers of the Trust Preferred Securities should note
that the ability to settle secondary market trades of the Trust Preferred
Securities effected on the date of pricing and the next business day may be
affected by the T+5 settlement.

  In order to facilitate the offering of the Trust Preferred Securities, the
underwriters may engage in transactions that stabilize, maintain, or otherwise
affect the price of the Trust Preferred Securities. Specifically, the
underwriters may over-allot in connection with the offering, creating a short
position in the Trust Preferred Securities for their account. In addition, to
cover over-allotments or to stabilize the price of the Trust Preferred
Securities, the underwriters may bid for, and purchase, the Trust Preferred
Securities in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
Trust Preferred Securities in the offering if the syndicate repurchases
previously distributed Trust Preferred Securities in transactions to cover
syndicate short positions, in stabilization transactions, or otherwise. Any of
these activities may stabilize or maintain the market price of the Trust
Preferred Securities above independent market levels. The underwriters are not
required to engage in these activities, and may end any of these activities at
any time.

  CNG and the Trust have agreed to indemnify each of the underwriters against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended.

  Some of the underwriters and their affiliates engage in transactions with,
and from time to time have performed services for, Dominion and its
subsidiaries, including CNG and its subsidiaries, in the ordinary course of
business.

              UNAUDITED PRO FORMA COMBINED CONDENSED CONSOLIDATED
                                 FINANCIAL DATA

Unaudited Pro Forma Information

    The unaudited pro forma information reflects the historical combined
condensed consolidated financial data of CNG and Louis Dreyfus after accounting
for the proposed acquisition of Louis Dreyfus by a wholly owned subsidiary of
Dominion and the transfer of such investment in Louis Dreyfus to CNG.

    Louis Dreyfus is one of the largest independent natural gas companies in
the United States engaged in the acquisition, development, exploration,
production and marketing of natural gas and crude oil. Its acquisition,
development and exploration activities are primarily conducted in three
geographically concentrated core areas: the Permian Region which includes west
Texas, southeast New Mexico and the San Juan Basin; the Mid-Continent Region
which includes Oklahoma, Kansas, the panhandle of Texas, east Texas, southwest
Arkansas and north Louisiana; and the Gulf Coast Region, which includes south
Texas and offshore Gulf of Mexico. Its proved reserves as of December 31, 2000
totaled 1.8 Tcfe.

    The acquisition of Louis Dreyfus is reported as a purchase business
combination, as more fully explained under "Accounting Treatment" below.
Accordingly, you should read the following information together with the
historical consolidated financial statements of CNG and Louis Dreyfus and all
related notes, which are incorporated into this prospectus supplement by
reference.

    The Unaudited Pro Forma Combined Condensed Consolidated Statements of
Income from Continuing Operations assume the acquisition of Louis Dreyfus
became effective on January 1, 2000. The Unaudited Pro Forma Combined Condensed
Consolidated Balance Sheet assumes the acquisition of Louis Dreyfus became
effective as of June 30, 2001.

    The unaudited pro forma information is not necessarily indicative of the
results of operations that might have occurred had the acquisition actually
closed on January 1, 2000, or the actual financial position that might have
resulted had the acquisition actually closed on June 30, 2001. The information
is also not indicative of the future results of operations or financial
position of CNG.

The Transaction

    In September 2001, Dominion and Louis Dreyfus signed a merger agreement
which provides for the merger of Louis Dreyfus into a newly formed, direct,
wholly owned subsidiary of Dominion. The consummation of the merger is subject
to the approval of the stockholders of Louis Dreyfus, approvals under the
Federal antitrust laws and by the SEC and other customary closing conditions.

    The merger agreement also provides that immediately after the merger,
Dominion will contribute the surviving subsidiary to CNG. Merger consideration
offered for each share of Louis Dreyfus common stock includes cash
consideration of $20.00 plus 0.3226 share of Dominion common stock. In
addition, all employee and director stock options may be

                                      S-38


exchanged for equivalent options to purchase shares of Dominion common stock.
Funding for the cash consideration paid to Louis Dreyfus common shareholders is
expected to be provided by the issuance of a combination of long-term debt and
trust preferred securities by CNG.

    The unaudited pro forma information assumes total consideration for the
acquisition of Louis Dreyfus to be approximately $1.8 billion, excluding the
assumption of $523 million of Louis Dreyfus debt, based on the per share
consideration described above.

    A special meeting of the shareholders of Louis Dreyfus will be held on
October 30, 2001 to consider and vote upon the proposed merger.

Accounting Treatment

    The acquisition of Louis Dreyfus will be accounted for by the purchase
method of accounting by CNG. Under the purchase method, identifiable assets and
liabilities of Louis Dreyfus will be recorded at their fair values. The
remaining difference between the purchase price of Louis Dreyfus, including
direct costs of the acquisition, will be recorded as goodwill. Allocations
included in the unaudited pro forma statements are based on preliminary
analysis. Accordingly, the final value of the purchase price and its allocation
may differ, perhaps significantly, from the amount included in these pro forma
financial statements.

                        CONSOLIDATED NATURAL GAS COMPANY

                NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED
                          CONSOLIDATED FINANCIAL DATA

    The Unaudited Pro Forma Combined Condensed Consolidated Financial Data are
based on the following assumptions:

A.  Certain revenues, expenses, assets and liabilities of Louis Dreyfus have
    been reclassified to conform with CNG's presentation.

B.  The issuance of $675 million of long-term debt and $200 million of trust
    preferred securities by CNG at an average rate of 6.75% to fund the cash
    consideration distributed in exchange for the outstanding shares of Louis
    Dreyfus at the closing of the merger. Also, CNG anticipates retiring an
    estimated $225 million of Louis Dreyfus bank debt with proceeds from the
    issuance of additional long-term debt.

C.  Dominion's transfer of its wholly owned subsidiary, into which Louis
    Dreyfus was merged, to CNG as a capital contribution. The net assets of
    this subsidiary total $916 million and include 1) $884 million, the
    estimated value of the 14.1 million shares of Dominion common stock
    distributed at the closing of the merger based on the exchange ratio of
    0.3226 share of Dominion common stock for each share of Louis Dreyfus
    common stock; and 2) the conversion of Louis Dreyfus employee stock options
    into Dominion common stock options with an estimated fair value of $32
    million.

D.  Purchase adjustments which have been made to the assets and liabilities of
    Louis Dreyfus to reflect the effect of the merger accounted for as a
    purchase business combination are as follows (in millions):

  Purchase Adjustments


                                                                      
   Total oil and gas exploration and production properties(1)........... $1,227
   Goodwill(2)..........................................................    242
   Deferred taxes(3)....................................................    449


  1.  Oil and gas exploration and production properties are adjusted to
      reflect the Louis Dreyfus exploration and production properties at
      estimated fair value. The fair value of proved reserves were estimated
      to be $1.8 billion and unproved properties were estimated to be $842
      million.

  2.  Goodwill is recognized, representing the portion of the purchase price
      in excess of the estimated fair value of identified assets and
      liabilities. No amortization of goodwill is included in the Unaudited
      Pro Forma Combined Condensed Consolidated Financial Data, as provided
      in Statement of Financial Accounting Standards No. 142, Goodwill and
      Other Intangible Assets, for business combinations completed after
      June 30, 2001. The allocation of the purchase price will be based on
      the fair value of identified assets and liabilities as of the date the
      business combination is completed. Accordingly, goodwill will be
      adjusted as a result of the determination of such fair values and thus
      will differ from the amount

                                      S-42


      reported in the Unaudited Pro Forma Combined Condensed Consolidated
      Balance Sheet.

  3.  Deferred taxes are adjusted to record the additional deferred taxes,
      resulting primarily from the recognition of the estimated fair value
      of the Louis Dreyfus exploration and production properties. The
      estimated provision for income taxes related to the pro forma
      adjustments are based on an assumed combined federal and state income
      tax rate of 38%.

E.  Pro forma adjustments reflect the additional depletion related to the
    adjustment of the Louis Dreyfus exploration and production properties to
    estimated fair value under the full cost method of accounting. See Note G.

F.  The companies expect to record direct costs of the merger (including fees
    of financial advisors, legal counsel, independent auditors and payments
    under certain employment contracts). The direct costs of the merger are
    estimated to be $19 million. The estimated charges and nature of costs
    included therein are subject to change, as more accurate estimates become
    available. The Unaudited Pro Forma Combined Condensed Consolidated
    Financial Data do not reflect the nonrecurring costs and expenses
    associated with integrating the operations of the two companies, nor any
    of the anticipated recurring expense savings arising from the integration.

G.  CNG uses the full cost method to account for its oil and gas operations.
    Louis Dreyfus utilizes the successful efforts method of accounting for its
    oil and gas operations. The pro forma data reflect an estimate of the
    change from the successful efforts method to the full cost method for the
    Louis Dreyfus oil and gas operations. This change resulted in a $10
    million and $6 million increase in after-tax earnings in the Unaudited Pro

THE COMPANY

    We are a public utility holding company regulated under the Public Utility
Holding Company Act of 1935. Acting through our subsidiaries, we are engaged
in all phases of the natural gas business--distribution, transmission,
exploration and production. Our principal subsidiaries are described below.

    Distribution. Our public utility subsidiaries are Dominion East Ohio,
Dominion Peoples, and Dominion Hope. Principal cities served at retail are:
Cleveland, Akron, Youngstown, Canton, Warren, Lima, Ashtabula and Marietta in
Ohio; Pittsburgh (a portion), Altoona and Johnstown in Pennsylvania; and
Clarksburg and Parkersburg in West Virginia. We currently serve at retail
approximately 1.7 million residential, commercial and industrial gas sales and
transportation customers.

    Transmission and Storage. Dominion Transmission, Inc. operates a regional
interstate pipeline system and provides gas transportation and storage
services to each of our public utility subsidiaries and to non-affiliated
utilities, end-users and others in the Midwest, the Mid-Atlantic states and
the Northeast. Through its wholly owned subsidiary, Dominion Iroquois, Inc.,
Dominion Transmission holds a 16 percent general partnership interest in the
Iroquois Gas Transmission System, L.P., that owns and operates an interstate
natural gas pipeline extending from the Canada-United States border near
Iroquois, Ontario, to Long Island, New York. The Iroquois pipeline transports
Canadian gas to utility and power generation customers in metropolitan New
York and New England. Dominion Transmission, Inc., along with Dominion East
Ohio and Dominion Peoples, operates a combined 26 natural gas storage fields
with 885 Bcf of storage capacity. Dominion Transmission, Inc., is subject to
regulation by the Federal Energy Regulatory Commission.

    Exploration and Production. Dominion Exploration and Production, Inc. is
our exploration and production subsidiary. It explores for and produces gas
and oil primarily in the onshore and offshore Gulf of Mexico region, the
southern and western United States and the Appalachian region.

    Retail Marketing. Dominion Retail Services Corporation was created in 1997
to market natural gas, electricity and related products and services to
residential, commercial and small industrial customers. Dominion Products and
Services, Inc. also provides energy-related services to customers of our local
distribution subsidiaries and others.

    Merger. Effective January 28, 2000, Consolidated Natural Gas Company, our
predecessor corporation, merged into us and became a wholly-owned subsidiary
of Dominion Resources, Inc., a fully integrated gas and electric energy
holding company. Following the merger, we sold our ownership interest in
Virginia Natural Gas, Inc., as required by the terms of the SEC order
approving the transaction. We also have sold our CNG International operations
in Latin America and are actively exploring the sale of our operations in
Australia. Restructuring and merger-related costs incurred during the course
of the past year are more fully described in our most recent Quarterly Report
on Form 10-Q, which is incorporated by reference.

                                       4


    Dominion Resources manages our operations, together with those of its other
subsidiaries, along functional lines in energy, delivery, and exploration and
production segments rather than by corporate entity.

    Dominion Resources does not guarantee any of the debt securities offered
hereby.

THE TRUST

    Dominion CNG Capital Trust I is a statutory business trust newly formed
under Delaware law by us, as sponsor for the Trust, and Bank One Delaware, Inc.
as trustee. The trust agreement for the Trust will be amended and restated
substantially in the form filed as an exhibit to the registration statement,
effective when securities of the Trust are initially issued. The amended trust
agreement will be qualified as an indenture under the Trust Indenture Act of
1939.

    The Trust exists for the exclusive purposes of

 . issuing two classes of trust securities, trust preferred securities and trust
  common securities, which together represent undivided beneficial interests in
  the assets of the Trust;

 . investing the gross proceeds of the trust securities in our Junior
  Subordinated Debentures;

 . making distributions; and

 . engaging in only those other activities necessary, advisable or incidental to
  the purposes listed above.

    The Junior Subordinated Debentures will be the sole assets of the Trust,
and our payments under the Junior Subordinated Debentures and the Agreement as
to Expenses and Liabilities will be the sole revenue of the Trust.

    No separate financial statements of the Trust are included in this
prospectus. We consider that these financial statements would not be material
to holders of the Trust preferred securities because the Trust has no
independent operations and the purposes of the Trust are as described above. We
do not expect that the Trust will be filing annual, quarterly or special
reports with the SEC.

    The principal place of business of the Trust will be c/o Consolidated
Natural Gas Company, 120 Tredegar Street, Richmond, VA 23219.

USE OF PROCEEDS

    The proceeds from the sale of the securities offered by this prospectus
will be added to our treasury funds and subsequently used (either directly or
by repaying short-term indebtedness incurred for such purposes) to finance
capital expenditures, for general corporate purposes, and to retire or redeem
debt securities issued by us as authorized by the SEC under the Public Utility
Holding Company Act. The balance of funds required for these purposes is
expected to be obtained principally from internal cash generation and the
issuance of other debt. Reference is made to the documents incorporated by
reference herein for information relating to estimated capital expenditures.

DESCRIPTION OF DEBT SECURITIES

    The term Debt Securities includes the Senior Debt Securities and the Junior
Subordinated Debentures. We will issue the Senior Debt Securities in one or
more series under a Senior Indenture between us and Bank One Trust Company,
National Association, as Trustee, and the Junior Subordinated Debentures in one
or more series under a Junior Subordinated Indenture between us and Bank One
Trust Company, National Association, as Trustee. The Indenture related to the
Junior Subordinated Debentures is called the Subordinated Indenture in this
prospectus, and together the Senior Indenture and the Subordinated Indenture
are called Indentures. We have summarized selected provisions of the Indentures
below. The forms of the Senior Indenture and the Subordinated Indenture have
been filed as exhibits to the registration statement, and you should read the
Indentures for provisions that may be important to you. In the summary below,
we have included references to section numbers of the Indentures so that you
can easily locate these provisions. Capitalized terms used in this description
have the meanings specified in the Indentures.

General

    The Senior Debt Securities will be our direct, unsecured obligations and
will rank equally with all of our other senior and unsubordinated debt. The
Junior Subordinated Debentures will be our unsecured obligations and are junior
in right of payment to our Senior Indebtedness, as described under the caption
ADDITIONAL TERMS OF JUNIOR SUBORDINATED DEBENTURES--SUBORDINATION.

    Because we are a holding company that conducts all of our operations
through our subsidiaries, our ability to meet our obligations under the Debt
Securities is dependent on the earnings and cash flows of those subsidiaries
and the ability of those subsidiaries to pay dividends or to advance or repay
funds to us. Holders of Debt Securities will generally have a junior position
to claims of creditors of our subsidiaries, including trade creditors,
debtholders, secured creditors, taxing authorities, guarantee holders and any
preferred stockholders.

    Neither of the Indentures limits the amount of Debt Securites that we may
issue under it. We may issue Debt Securities from time to time under the
Indentures in one or more series by entering into supplemental indentures or by
our Board of Directors or a duly authorized committee authorizing the issuance.
A form of supplemental indenture to the Senior Indenture is an exhibit to the
registration statement.

    The Indentures do not protect the holders of Debt Securities if we engage
in a highly leveraged transaction.

Provisions of a Particular Series

    The Debt Securities of a series need not be issued at the same time, bear
interest at the same rate or mature on the same

                                       6


date. The prospectus supplement for a particular series of Debt Securities will
specify the terms of that series, including, if applicable, some or all of the
following:

 . the title and type of the Debt Securities;

 . the total principal amount of the Debt Securities;

 . the portion of the principal payable upon acceleration of maturity, if other
  than the entire principal;

 . the date or dates on which principal is payable or the method for determining
  the date or dates, and any right that we have to change the date on which
  principal is payable;

 . the interest rate or rates, if any, or the method for determining the rate or
  rates, and the date or dates from which interest will accrue;

 . any interest payment dates and the regular record date for the interest
  payable on each interest payment date, if any;

 . any payments due if the maturity of the Debt Securities is accelerated;

 . any optional redemption terms, or, with respect to the Senior Debt
  Securities, any repayment terms;

 . any provisions that would obligate us to repurchase or otherwise redeem the
  Debt Securities, or, with respect to the Senior Debt Securities, any sinking
  fund provisions;

 . the currency in which payments will be made if other than U.S. dollars, and
  the manner of determining the equivalent of those amounts in U.S. dollars;

 . if payments may be made, at our election or at the holder's election, in a
  currency other than that in which the Debt Securities are stated to be
  payable, then the currency in which those payments may be made, the terms and
  conditions of the election and the manner of determining those amounts;

 . any index or formula used for determining principal, interest, or premium, if
  any;

 . the percentage of the principal amount at which the Debt Securities will be
  issued, if other than 100% of the principal amount;

 . whether the Debt Securities are to be issued in fully registered certificated
  form or in book-entry form represented by certificates deposited with, or on
  behalf of, a securities depositary and registered in the name of the
  depositary's nominee (Book-Entry Debt Securities);

 . denominations, if other than $1,000 each or multiples of $1,000;

 . any changes to events of defaults or covenants; and

 . any other terms of the Debt Securities. (Sections 201 & 301 of the Senior
  Indenture & Sections 2.1 & 2.3 of the Subordinated Indenture.)

    The prospectus supplement will also indicate any special tax implications
of the Debt Securities and any provisions granting special rights to holders
when a specified event occurs.

Conversion or Redemption

    No Debt Security will be subject to conversion, amortization, or
redemption, unless otherwise provided in the applicable prospectus supplement.
Any provisions relating to the conversion or redemption of Debt Securities will
be set forth in the

                                       7


applicable prospectus supplement, including whether conversion is mandatory or
at our option. If no redemption date or redemption price is indicated with
respect to a Debt Security, we cannot redeem the Debt Security before Stated
Maturity. Debt Securities subject to redemption by us will be subject to the
following terms:

 . redeemable on and after the applicable redemption dates;

 . redemption dates and redemption prices fixed at the time of sale and set
  forth on the Debt Security; and

 . redeemable in whole or in part (provided that any remaining principal amount
  of the Debt Security will be equal to an authorized denomination) at our
  option at the applicable redemption price, together with interest, payable to
  the date of redemption, on notice given not more than 60 nor less than 20
  days before the date of redemption. (Section 1104 of the Senior Indenture &
  Section 3.2 of the Subordinated Indenture.)

    We will not be required to:

 . issue, register the transfer of, or exchange any Debt Securities of a series
  during the period beginning 15 days before the date the notice is mailed
  identifying the Debt Securities of that series that have been selected for
  redemption; or

 . register the transfer of, or exchange any Debt Security of that series
  selected for redemption except the unredeemed portion of a Debt Security
  being partially redeemed. (Section 305 of the Senior Indenture & Section 2.5
  of the Subordinated Indenture.)

Payment and Transfer; Paying Agent

    The paying agent will pay the principal of any Debt Securities only if
those Debt Securities are surrendered to it. Unless we state otherwise in the
applicable prospectus supplement, the paying agent will pay principal, interest
and premium, if any, on Debt Securities, subject to such surrender, where
applicable, at its office or, at our option:

 . by wire transfer to an account at a banking institution in the United States
  that is designated in writing to the Trustee before the deadline set forth in
  the applicable prospectus supplement by the person entitled to that payment
  (which in the case of Book-Entry Debt Securities is the securities depositary
  or its nominee); or

 . by check mailed to the address of the person entitled to that interest as
  that address appears in the security register for those Debt Securities.
  (Sections 307 & 1001 of the Senior Indenture & Section 4.1 of the
  Subordinated Indenture.)

    Neither we nor the Trustee will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests in a Book-Entry Debt Security, or for maintaining,
supervising or reviewing any records relating to the beneficial ownership
interests. We expect that the securities depositary, upon receipt of any
payment of principal, interest or premium, if any, in a Book-Entry Debt
Security, will credit immediately the accounts of the related participants with
payment in amounts proportionate to their respective holdings in principal
amount of beneficial interest in the Book-Entry Debt Security as shown on

                                       8


the records of the securities depositary. We also expect that payments by
participants to owners of beneficial interests in a Book-Entry Debt Security
will be governed by standing customer instructions and customary practices, as
is now the case with securities held for the accounts of customers in bearer
form or registered in "street name" and will be the responsibility of the
participants.

    Unless we state otherwise in the applicable prospectus supplement, the
Trustee will act as paying agent for the Debt Securities, and the principal
corporate trust office of the Trustee will be the office through which the
paying agent acts. We may, however, change or add paying agents or approve a
change in the office through which a paying agent acts. (Section 1002 of the
Senior Indenture & Section 4.4 of the Subordinated Indenture.)

    Any money that we have paid to a paying agent for principal or interest on
any Debt Securities which remains unclaimed at the end of two years after that
principal or interest has become due will be repaid to us at our request. After
repayment to the Company, holders should look only to us for those payments.
(Section 1003 of the Senior Indenture & Section 12.4 of the Subordinated
Indenture.)

    Fully registered securities may be transferred or exchanged at the
corporate trust office of the Trustee or at any other office or agency we
maintain for those purposes, without the payment of any service charge except
for any tax or governmental charge and related expenses. (Section 305 of the
Senior Indenture & Section 2.5 of the Subordinated Indenture.)

Global Securities

    We may issue some or all of the Debt Securities as Book-Entry Debt
Securities. Book-Entry Debt Securities will be represented by one or more fully
registered global certificates. Book-Entry Debt Securities of like tenor and
terms up to $400,000,000 aggregate principal amount may be represented by a
single global certificate. Each global certificate will be deposited and
registered with the securities depositary or its nominee or a custodian for the
securities depositary. Unless it is exchanged in whole or in part for Debt
Securities in definitive form, a global certificate may generally be
transferred only as a whole unless it is being transferred to certain nominees
of the depositary. (Section 305 of the Senior Indenture & Section 2.5 of the
Subordinated Indenture.)

    Unless otherwise stated in any prospectus supplement, The Depository Trust
Company will act as the securities depositary. Beneficial interests in global
certificates will be shown on, and transfers of global certificates will be
effected only through, records maintained by the securities depositary and its
participants. If there are any additional or differing terms of the depositary
arrangement with respect to the Book-Entry Debt Securities, we will describe
them in the applicable prospectus supplement.

    Holders of beneficial interests in Book-Entry Debt Securities represented
by a global certificate are referred to as beneficial owners. Beneficial owners
will be limited to institutions having accounts with the securities depositary
or its nominee, which are called participants in this discussion, and to
persons that hold beneficial interests through participants.

                                       9


When a global certificate representing Book-Entry Debt Securities is issued,
the securities depositary will credit on its book-entry, registration and
transfer system the principal amounts of Book-Entry Debt Securities the global
certificate represents to the accounts of its participants. Ownership of
beneficial interests in a global certificate will be shown only on, and the
transfer of those ownership interests will be effected only through, records
maintained by:

 . the securities depositary, with respect to participants' interests; and

 . any participant, with respect to interests the participant holds on behalf of
  other persons.

    As long as the securities depositary or its nominee is the registered
holder of a global certificate representing Book-Entry Debt Securities, that
person will be considered the sole owner and holder of the global certificate
and the Book-Entry Debt Securities it represents for all purposes. Except in
limited circumstances, beneficial owners:

 . may not have the global certificate or any Book-Entry Debt Securities it
  represents registered in their names;

 . may not receive or be entitled to receive physical delivery of certificated
  Book-Entry Debt Securities in exchange for the global certificate; and

 . will not be considered the owners or holders of the global certificate or any
  Book-Entry Debt Securities it represents for any purposes under the Debt
  Securities or the Indentures. (Section 308 of the Senior Indenture & Section
  2.2 of the Subordinated Indenture.)

    We will make all payments of principal, interest and premium, if any, on a
Book-Entry Debt Security to the securities depositary or its nominee as the
holder of the global certificate. The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of securities in
definitive form. These laws may impair the ability to transfer beneficial
interests in a global certificate.

    Payments participants make to beneficial owners holding interests through
those participants will be the responsibility of those participants. The
securities depositary may from time to time adopt various policies and
procedures governing payments, transfers, exchanges and other matters relating
to beneficial interests in a global certificate. None of the following will
have any responsibility or liability for any aspect of the securities
depositary's or any participant's records relating to beneficial interests in a
global certificate representing Book-Entry Debt Securities, for payments made
on account of those beneficial interests or for maintaining, supervising or
reviewing any records relating to those beneficial interests:

 . the Company;

 . the Trustee;

 . the Trust (only with respect to the Junior Subordinated Debentures if the
  Junior Subordinated Debentures are issued to a Trust); or

 . any agent of any of the above.

Covenants

    Under the Indentures we will:

 . pay the principal, interest and premium, if any, on the Debt Securities when
  due;

 . maintain a place of payment;

 . deliver an officer's certificate to the Trustee at the end of each fiscal
  year

                                       10


  confirming our compliance with our obligations under each of the Indentures;
  and

 . deposit sufficient funds with any paying agent on or before the due date for
  any principal, interest or premium, if any. (Sections 1001, 1002, 1003 & 1006
  of the Senior Indenture & Sections 4.1, 4.2 4.4 & 4.5 of the Subordinated
  Indenture.)

Consolidation, Merger or Sale

    The Indentures provide that we may consolidate or merge with or into, or
sell all or substantially all our assets to, another Person, provided that any
successor assumes our obligations under the Indentures and the Debt Securities
issued under the Indentures. We must also deliver an opinion of counsel to the
Trustee affirming our compliance with all conditions in the applicable
Indenture relating to the transaction. When the conditions are satisfied, the
successor will succeed to and be substituted for us and, in the case of a sale
of all or substantially all our assets, we will be relieved of our obligations.
(Sections 801 & 802 of the Senior Indenture & Sections 11.1, & 11.2 of the
Subordinated Indenture.)

Events of Default

    Event of Default when used in each of the Indentures, will mean any of the
following with respect to Debt Securities of any series:

 . failure to pay the principal or any premium on any Debt Security of that
  series when due;

 . with respect to the Senior Debt Securities, failure to deposit any sinking
  fund payment for that series when due that continues for 60 days;

 . failure to pay any interest on any Debt Securities of that series, when due,
  that continues for 60 days; provided that, if applicable, for this purpose,
  the date on which interest is due is the date on which we are required to
  make payment following any deferral of interest payments by us under the
  terms of Junior Subordinated Debentures that permit such deferrals;

 . failure to perform any other covenant in the Indentures (other than a
  covenant expressly included solely for the benefit of other series) that
  continues for 90 days after the Trustee or the holders of at least 33% of the
  outstanding Debt Securities of that series give us written notice of the
  default;

 . certain events in bankruptcy, insolvency or reorganization of the Company; or

 . any other Event of Default included in the Indentures or any supplemental
  indenture. (Section 501 of the Senior Indenture & Section 6.1 of the
  Subordinated Indenture.)

    In the case of a general covenant default described above, the Trustee may
extend the grace period. In addition, if holders of a particular series have
given a notice of default, then holders of at least the same percentage of Debt
Securities of that series, together with the Trustee, may also extend the grace
period. The grace period will be automatically extended if we have initiated
and are diligently pursuing corrective action.

    An Event of Default for a particular series of Debt Securities does not
necessarily constitute an Event of Default for any other series of Debt
Securities issued under the Indentures. Additional

                                       11


events of default may be established for a particular series and, if
established, will be described in the applicable prospectus supplement.

    If an Event of Default for any series of Debt Securities occurs and
continues, the Trustee or the holders of at least 33% in aggregate principal
amount of the Debt Securities of the series may declare the entire principal of
all the Debt Securities of that series to be due and payable immediately. If
this happens, subject to certain conditions, the holders of a majority of the
aggregate principal amount of the Debt Securities of that series can void the
declaration. (Section 502 of the Senior Indenture & Section 6.1 of the
Subordinated Indenture.)

    The Trustee may withhold notice to the holders of Debt Securities of any
default (except in the payment of principal or interest) if it considers the
withholding of notice to be in the best interests of the holders. Other than
its duties in case of a default, a Trustee is not obligated to exercise any of
its rights or powers under the Indentures at the request, order or direction of
any holders, unless the holders offer the Trustee reasonable indemnity. If they
provide this reasonable indemnification, the holders of a majority in principal
amount of any series of Debt Securities may direct the time, method and place
of conducting any proceeding or any remedy available to the Trustee, or
exercising any power conferred upon the Trustee, for any series of Debt
Securities. (Sections 512, 601 & 602 of the Senior Indenture & Sections 6.6,
7.1 & 7.2 of the Subordinated Indenture.)

    The holder of any Debt Security will have an absolute and unconditional
right to receive payment of the principal, any premium and, within certain
limitations, any interest on that Debt Security on its maturity date or
redemption date and to enforce those payments. (Section 508 of the Senior
Indenture & Section 14.2 of the Subordinated Indenture.)

Satisfaction; Discharge

    We may discharge all our obligations (except those described below) to
holders of the Debt Securities issued under the Indentures, which Debt
Securities have not already been delivered to the Trustee for cancellation and
which either have become due and payable or are by their terms due and payable
within one year, or are to be called for redemption within one year, by
depositing with the Trustee an amount certified to be sufficient to pay when
due the principal, interest and premium, if any, on all outstanding Debt
Securities. However, certain of our obligations under the Indentures will
survive, including with respect to the following:

 . remaining rights to register the transfer, conversion, substitution or
  exchange of Debt Securities of the applicable series;

 . rights of holders to receive payments of principal of, and any interest on,
  the Debt Securities of the applicable series, and other rights, duties and
  obligations of the holders of Debt Securities with respect to any amounts
  deposited with the Trustee; and

 . the rights, obligations and immunities of the Trustee under the Indentures.
  (Section 401 of Senior Indenture & Section 12.1 of Subordinated Indenture.)

Modification of Indentures; Waiver

    Under the Indentures our rights and obligations and the rights of the
holders

                                       12


may be modified with the consent of the holders of a majority in aggregate
principal amount of the outstanding Debt Securities of each series affected by
the modification. No modification of the principal or interest payment terms,
and no modification reducing the percentage required for modifications, is
effective against any holder without its consent. (Section 902 of the Senior
Indenture & Section 10.2 of the Subordinated Indenture.) In addition, we may
supplement the Indentures to create new series of Debt Securities and for
certain other purposes, without the consent of any holders of Debt Securities.
(Section 901 of the Senior Indenture & Section 10.1 of the Subordinated
Indenture.)

    The holders of a majority of the outstanding Debt Securities of all series
under the applicable Indenture with respect to which a default has occurred and
is continuing may waive a default for all those series, except a default in the
payment of principal or interest, or any premium, on any Debt Securities or a
default with respect to a covenant or provision which cannot be amended or
modified without the consent of the holder of each outstanding Debt Security of
the series affected. (Section 513 of the Senior Indenture & Section 6.6 of the
Subordinated Indenture.)

    In addition, under certain circumstances, the holders of a majority of the
outstanding Junior Subordinated Debentures of any series may waive in advance,
for that series, our compliance with certain restrictive provisions of the
Subordinated Indenture under which those Junior Subordinated Debentures were
issued. (Section 4.6 of the Subordinated Indenture.)

Concerning the Trustee

    Bank One Trust Company, National Association, an affiliate of Bank One,
N.A., is the Trustee under the Indentures. We and certain of our affiliates
maintain deposit accounts and banking relationships with Bank One, N.A. Bank
One Trust Company, National Association also performs agency functions with
respect to other securities issued by our affiliates. Bank One, N.A. and its
affiliates have purchased, and are likely to purchase in the future, our
securities and securities of our affiliates.

    The Trustee will perform only those duties that are specifically set forth
in the Indentures unless an event of default under an Indenture occurs and is
continuing. The Trustee is under no obligation to exercise any of its powers
under the Indentures at the request of any holder of Debt Securities unless
that holder offers reasonable indemnity to the Trustee against the costs,
expenses and liabilities which it might incur as a result. (Section 601 of the
Senior Indenture & Section 7.1 of the Subordinated Indenture.)

    The Trustee administers its corporate trust business at 153 West 51st
Street, New York, New York 10019, Attention: Global Corporate Trust Services.

ADDITIONAL TERMS OF SENIOR DEBT SECURITIES

Limitation on Liens

    While any of the Senior Debt Securities are outstanding, we are not
permitted to create liens upon any Principal Property (as defined below) or
upon any shares of stock of any Material Subsidiary (as defined below), which
we now own or own in the future, to secure any of our debt,

                                       13


unless at the same time we provide that the Senior Debt Securities will also be
secured by that lien on an equal and ratable basis. However, we are generally
permitted to create the following types of liens:

    (1) purchase money liens on future property acquired by us; liens of any
  kind existing on property or shares of stock at the time they are acquired
  by us; conditional sales agreements and other title retention agreements
  on future property acquired by us (as long as none of those liens cover
  any of our other properties);

    (2) liens on our property or any shares of stock of any Material
  Subsidiary that exist as of the date of the Senior Indenture; liens on the
  shares of stock of any corporation, which liens existed at the time that
  corporation became a Material Subsidiary; certain liens typically incurred
  in the ordinary course of business;

    (3) liens in favor of the United States (or any State), any foreign
  country or any department, agency or instrumentality or political
  subdivision of those jurisdictions, to secure payments under any contract
  or statute or to secure any debt incurred for the purpose of financing the
  purchase price or the cost of constructing or improving the property
  subjet to those liens, including, for example, liens to secure debt of the
  pollution control or industrial revenue bond type;

    (4) debt that we may issue in connection with a consolidation or merger
  of the Company or any Material Subsidiary with or into any other Person
  (including any of our affiliates or Material Subsidiaries) in exchange for
  secured debt of that Person (Third Party Debt) as long as that debt (i) is
  secured by a mortgage on all or a portion of the property of that Person,
  (ii) prohibits secured debt from being incurred by that Person, unless the
  Third Party Debt is secured on an equal and ratable basis or (iii)
  prohibits secured debt from being incurred by that Person;

    (5) debt of another Person that we must assume in connection with a
  consolidation or merger of that Person, with respect to which any of our
  property is subjected to a lien;

    (6) liens on any property that we acquire, construct, develop or improve
  after the date the Senior Debt Securities are first issued that are
  created before or within 18 months after the acquisition, construction,
  development or improvement of the property and secrue the payment of the
  purchase price or related costs;

    (7) liens in our favor or in favor of our Material Subsidiaries or
  wholly-owned subsidiaries:

    (8) liens securing production payments on oil, gas, coal or other
  mineral properties;

    (9) the placement, extension or renewal of any lien referred to in (1)
  through (8) as long as the amount secrued by the liens or the property
  subject to the liens is not increased; and

    (10) any other lien not covered by (1) through (9) above as long as
  immediately after the creation of the lien the aggregate principal amount
  of debt secured by these liens does not exceed 10% of our common
  shareholders' equity.

                                       14


  When we use the term "lien" in this section, we mean any mortgage, lien,
  pledge, security interest or other encumbrance of any kind; "Material
  Subsidiary" means each of our subsidiaries whose total assets (as
  determined in accordance with GAAP) represent at least 20% of our total
  assets on a consolidated basis; and "Principal Property" means any of our
  plants and facilities (including pipelines) located in the United States
  that in the opinion of our Board of Directors or management is of material
  importance to the business conducted by us and our consolidated
  subsidiaries taken as a whole. (Section 1008 of the Senior Indenture.)

Repayment at the Option of the Holder; Repurchases by the Company

    We must repay the Senior Debt Securities at the option of the Holders
before the Stated Maturity Date only if specified in the applicable prospectus
supplement. Unless otherwise provided in the prospectus supplement, the Senior
Debt Securities subject to repayment at the option of the Holder will be
subject to repayment:

 . on the specified Repayment Dates; and

 . at a repayment price equal to 100% of the unpaid principal amount to be
  repaid, together with unpaid interest accrued to the Repayment Date. (Section
  1302 of the Senior Indenture.)

    For any Senior Debt Security to be repaid, the Trustee must receive, at its
office maintained for that purpose in the Borough of Manhattan, New York City
not more than 60 nor less than 30 calendar days before the date of repayment:

 . in the case of a certificated Senior Debt Security, the certificated Senior
  Debt Security and the form in the Senior Debt Security entitled Option of
  Holder to Elect Purchase duly completed; or

 . in the case of a book-entry Senior Debt Security, instructions to that effect
  from the beneficial owner to the securities depositary and forwarded by the
  securities depositary. Exercise of the repayment option by the Holder will be
  irrevocable. (Section 1303 of the Senior Indenture.)

    Only the securities depositary may exercise the repayment option in respect
of beneficial interests in the book-entry Senior Debt Securities. Accordingly,
beneficial owners that desire repayment in respect of all or any portion of
their beneficial interests must instruct the participants through which they
own their interests to direct the securities depositary to exercise the
repayment option on their behalf. All instructions given to participants from
beneficial owners relating to the option to elect repayment will be
irrevocable. In addition, at the time the instructions are given, each
beneficial owner will cause the participant through which it owns its interest
to transfer its interest in the book-entry Senior Debt Securites or the global
certificate representing the related book-entry Senior Debt Securities, on the
securities depositary's records, to the Trustee. See DESCRIPTION OF THE DEBT
SECURITIES--GLOBAL SECURITIES.

Defeasance

    We will be discharged from our obligations on the Senior Debt Securities of

                                       15


any series at any time if we deposit with the Trustee sufficient cash or
government securities to pay the principal, interest, any premium and any other
sums due to the stated maturity date or a redemption date of the Senior Debt
Securities of the series. If this happens, the holders of the Senior Debt
Securities of the series will not be entitled to the benefits of the Senior
Indenture except for registration of transfer and exchange of Senior Debt
Securities and replacement of lost, stolen or mutilated Senior Debt Securities.
(Section 402 of the Senior Indenture.)

    Under federal income tax law as of the date of this prospectus, a discharge
may be treated as an exchange of the related Senior Debt Securities. Each
holder might be required to recognize gain or loss equal to the difference
between the holder's cost or other tax basis for the Senior Debt Securities and
the value of the holder's interest in the trust. Holders might be required to
include as income a different amount than would be includable without the
discharge. We urge prospective investors to consult their own tax advisers as
to the consequences of a discharge, including the applicability and effect of
tax laws other than the federal income tax law.

ADDITIONAL TERMS OF THE JUNIOR SUBORDINATED DEBENTURES

Additional Covenants Applicable to Junior Subordinated Debentures

    Under the Subordinated Indenture, we will:

 . maintain 100% ownership of any Trust to which the Junior Subordinated
  Debentures have been issued while the Junior Subordinated Debentures remain
  outstanding; and

 . pay to any Trust to which the Junior Subordinated Debentures have been issued
  any taxes, duties, assessments or governmental charges of whatever nature
  (other than withholding taxes) imposed by the United States or any other
  taxing authority on that Trust, so that the net amounts received and retained
  by that Trust (after paying any taxes, duties, assessments or other
  governmental charges) will be not less than the Trust would have received had
  no such taxes, duties, assessments or other governmental charges been
  imposed. (Sections 4.7 & 4.8 of the Subordinated Indenture.)

                                       16


Option to Extend Interest Payment Period

    We can defer interest payments by extending the interest payment period for
the number of consecutive extension periods specified in the applicable
prospectus supplement (each, an Extension Period). Other details regarding the
Extension Period will also be specified in the applicable prospectus
supplement. No Extension Period may extend beyond the maturity of the Junior
Subordinated Debentures. At the end of the Extension Period(s), we will pay all
interest then accrued and unpaid, together with interest compounded quarterly
at the rate for the Junior Subordinated Debentures, to the extent permitted by
applicable law. (Section 2.10 of the Subordinated Indenture.)

    During any Extension Period, we will not make distributions related to our
capital stock, including dividends, redemptions, repurchases, liquidation
payments, or guarantee payments. Also we will not make any payments, redeem or
repurchase any debt securities of equal or junior rank to the Junior
Subordinated Debentures or make any guarantee payments on any such debt
securities. We may, however, make the following types of distributions:

 . dividends paid in common stock;

 . dividends in connection with the implementation of a shareholder rights plan;

 . payments to a trust holding securities of the same series under a guarantee;
  or

 . repurchases, redemptions or other acquisitions of shares of our capital stock
  in connection with any employment contract, benefit plan or other similar
  arrangement with or for the benefit of employees, officers, directors or
  consultants.

Subordination

    Each series of Junior Subordinated Debentures will be subordinate and
junior in right of payment, to the extent set forth in the Subordinated
Indenture, to all Senior Indebtedness as defined below. If:

 . we make a payment or distribution of any of our assets to creditors upon our
  dissolution, winding-up, liquidation or reorganization, whether in
  bankruptcy, insolvency or otherwise;

 . a default beyond any grace period has occurred and is continuing with respect
  to the payment of principal, interest or any other monetary amounts due and
  payable on any Senior Indebtedness; or

 . the maturity of any Senior Indebtedness has been accelerated because of a
  default on that Senior Indebtedness,

then the holders of Senior Indebtedness generally will have the right to
receive payment, in the case of the first instance, of all amounts due or to
become due upon that Senior Indebtedness, and, in the case of the second and
third instances, of all amounts due on that Senior Indebtedness, or we will
make provision for those payments, before the holders of any Junior
Subordinated Debentures have the right to receive any payments of principal or
interest on their Junior Subordinated Debentures. (Sections 14.1 and 14.9 of
the Subordinated Indenture.)

    Senior Indebtedness means, with respect to any series of Junior
Subordinated Debentures, the principal, premium, interest and any other payment
in respect of any of the following:

 . all of our indebtedness for borrowed or purchased money that is evidenced by
  notes, debentures, bonds or other written instruments;

                                       17


 . our obligations for reimbursement under letters of credit, banker's
  acceptances, security purchase facilities or similar facilities issued for
  our account;

 . capitalized lease obligations;

 . any of our other indebtedness or obligations with respect to commodity
  contracts, interest rate commodity and currency swap agreements and other
  similar agreements or arrangements; and

 . all indebtedness of others of the kinds described in the preceding categories
  which we have assumed or guaranteed.

    Senior Indebtedness will not include our obligations to trade creditors or
indebtedness to our subsidiaries. (Section 1.1 of the Subordinated Indenture.)

    Senior Indebtedness will be entitled to the benefits of the subordination
provisions in the Subordinated Indenture irrespective of the amendment,
modification or waiver of any term of the Senior Indebtedness. We may not amend
the Subordinated Indenture to change the subordination of any outstanding
Junior Subordinated Debentures without the consent of each holder of Senior
Indebtedness that the amendment would adversely affect. (Sections 10.2 & 14.7
of the Subordinated Indenture.)

    The Subordinated Indenture does not limit the amount of Senior Indebtedness
that we may issue.

DESCRIPTION OF THE TRUST PREFERRED SECURITIES

    The following is a summary of the principal terms of the Trust Preferred
Securities. The form of amended trust agreement is filed as an exhibit to the
registration statement of which this prospectus forms a part, or is
incorporated by reference. The terms of the Trust Preferred Securities will
include those stated in the amended trust agreement and those made part of the
amended trust agreement by the Trust Indenture Act.

General

    The Trust will exist until terminated as provided in its amended trust
agreement. Except under certain circumstances, we will be entitled to appoint,
remove, or replace trustees, who will conduct the business and affairs of the
Trust. The trustees of the Trust will consist of:

 . two employees, officers or affiliates of the Company as Administrative
  Trustees;

 . a financial institution unaffiliated with us that will act as property
  trustee and as indenture trustee for purposes of the Trust Indenture Act,
  under the terms set forth in a prospectus supplement (the Property Trustee);
  and

 . one trustee with its principal place of business or who resides in the State
  of Delaware and who will act under the terms set forth in a prospectus
  supplement. (Sections 6.1 through 6.5 of the Amended Trust Agreement.)

    The amended trust agreement will authorize the Administrative Trustees to
issue, on behalf of the Trust, two classes of trust securities, Trust Preferred
Securities and trust common securities, each of which will have the terms
described in this prospectus and in the applicable prospectus supplement. We
will own all of the trust common securities. The trust common securities will
rank equally in right of payment, and payments will be made on the trust common
securities, proportionately with the Trust Preferred Securities.

                                       18


However, if an event of default occurs and is continuing under the amended
trust agreement, the rights of the holders of the trust common securities to
payment for distributions and payments upon liquidation, redemption and
otherwise, will be subordinated to the rights of the holders of the Trust
Preferred Securities. We will acquire, directly or indirectly, trust common
securities in a total liquidation amount of approximately 3% of the total
capital of the Trust. (Sections 3.6, 5.1, 5.2 and 7.1 of the Amended Trust
Agreement.)

    The proceeds from the sale of the Trust Preferred Securities will be used
by the applicable Trust to purchase our Junior Subordinated Debentures. These
Junior Subordinated Debentures will be held in trust by the Property Trustee
for the benefit of the holders of the trust securities. We will guarantee the
payments of distributions and payments on redemption or liquidation with
respect to the Trust Preferred Securities, but only to the extent the Trust has
funds available to make those payments and has not made the payments. See
DESCRIPTION OF THE GUARANTEE.

    The assets of the Trust available for distribution to the holders of Trust
Preferred Securities will be limited to payments from us under the Junior
Subordinated Debentures held by the Trust. If we fail to make a payment on the
Junior Subordinated Debentures, the Trust will not have sufficient funds to
make related payments, including distributions, on its Trust Preferred
Securities.

    The Guarantee, when taken together with our obligations under the Junior
Subordinated Debentures, the Subordinated Indenture and the amended trust
agreement, will provide a full and unconditional guarantee of amounts due on
the Trust Preferred Securities issued by the Trust.

    The Trust Preferred Securities will have the terms, including
distributions, redemption, voting, liquidation rights and other preferred,
deferred or other special rights or restrictions that will be described in the
amended trust agreement or made part of the amended trust agreement by the
Trust Indenture Act or the Delaware Business Trust Act. The terms of the Trust
Preferred Securities will mirror the terms of the Junior Subordinated
Debentures held by the Trust. In other words, the distribution rate and the
distribution payment dates and other payment dates for the Trust Preferred
Securities will correspond to the interest rate and interest payment dates and
other payment dates on the Junior Subordinated Debentures. Holders of Trust
Preferred Securities have no preemptive or similar rights. (Section 7.1 of the
Amended Trust Agreement.)

Provisions of a Particular Series

    The Trust may issue only one series of Trust Preferred Securities. The
applicable prospectus supplement will set forth the principal terms of the
Trust Preferred Securities that will be offered, including:

 . the name of the Trust Preferred Securities;

 . the liquidation amount and number of Trust Preferred Securities issued;

 . the annual distribution rate(s) or method of determining such rate(s), the
  payment date(s) and the record dates used to determine the holders who are to
  receive distributions;

 . the date from which distributions will be cumulative;


                                       19


 . the optional redemption provisions, if any, including the prices, time
  periods and other terms and conditions on which the Trust Preferred
  Securities will be purchased or redeemed, in whole or in part;

 . the terms and conditions, if any, upon which the Junior Subordinated
  Debentures and the related Guarantee may be distributed to holders of those
  Trust Preferred Securities;

 . any securities exchange on which the Trust Preferred Securities will be
  listed;

 . whether the Trust Preferred Securities are to be issued in book-entry form
  and represented by one or more global certificates, and if so, the depository
  for those global certificates and the specific terms of the depositary
  arrangements; and

 . any other relevant rights, preferences, privileges, limitations or
  restrictions of the Trust Preferred Securities. (Article 7 of the Amended
  Trust Agreement.)

    The interest rate and interest and other payment dates of Junior
Subordinated Debentures issued to the Trust will correspond to the rate at
which distributions will be paid and the distribution and other payment dates
of the Trust Preferred Securities of that Trust.

Extensions

    We have the right under the Subordinated Indenture to defer payments of
interest on the Junior Subordinated Debentures by extending the interest
payment period from time to time on the Junior Subordinated Debentures. The
Administrative Trustees will give the holders of the Trust Preferred Securities
notice of any Extension Period upon their receipt of notice from us. If
distributions are deferred, the deferred distributions and accrued interest
will be paid to holders of record of the Trust Preferred Securities as they
appear on the books and records of the Trust on the record date next following
the termination of such deferral period. See ADDITIONAL TERMS OF JUNIOR
SUBORDINATED DEBENTURES--OPTION TO EXTEND INTEREST PAYMENT PERIOD.

Distributions

    Distributions on the Trust Preferred Securities will be made on the dates
payable to the extent that the Trust has funds available for the payment of
distributions in the Property Account. The Trust's funds available for
distribution to the holders of the trust securities will be limited to payments
received from us on the Junior Subordinated Debentures. We have guaranteed the
payment of distributions out of monies held by the Trust to the extent set
forth under DESCRIPTION OF THE GUARANTEE.

    Distributions on the Trust Preferred Securities will be payable to the
holders named on the securities register of the Trust at the close of business
on the relevant record dates, which, as long as the Trust Preferred Securities
remain in book-entry only form, will be one business day before the relevant
payment dates. Distributions will be paid through the Property Trustee who will
hold amounts received in respect of the Junior Subordinated Debentures in the
Property Account for the benefit of the holders of the trust securities. If the
Trust Preferred Securities do not continue to remain in book-entry only form,
the relevant record dates will conform to the rules of any securities exchange
on which

                                       20


the Trust Preferred Securities are listed and, if none, the Administrative
Trustees will have the right to select relevant record dates, which will be
more than 14 days but less than 60 days before the relevant payment dates. If
any date on which distributions are to be made on the Trust Preferred
Securities is not a business day, then payment of the distributions payable on
that date will be made on the next succeeding day which is a business day and
without any interest or other payment in respect of that delay, except that, if
that business day is in the next succeeding calendar year, the payment will be
made on the immediately preceding business day, in each case with the same
force and effect as if made on the record date. (Section 7.2 of the Amended
Trust Agreement.)

Mandatory Redemption of Trust Preferred Securities

    The Trust Preferred Securities have no stated maturity date, but will be
redeemed upon the maturity of the Junior Subordinated Debentures or to the
extent the Junior Subordinated Debentures are redeemed before maturity. The
Junior Subordinated Debentures will mature on the date specified in the
applicable prospectus supplement and may be redeemed at any time, in whole but
not in part, in certain circumstances upon the occurrence of a Tax Event or an
Investment Company Event as described under SPECIAL EVENT REDEMPTION.

    Upon the maturity of the Junior Subordinated Debentures, the proceeds of
their repayment will simultaneously be applied to redeem all the outstanding
trust securities at the Redemption Price. Upon the redemption of the Junior
Subordinated Debentures, either at our option or as a result of a Tax Event or
an Investment Company Event, the proceeds from the redemption will
simultaneously be applied to redeem trust securities having a total liquidation
amount equal to the total principal amount of the Junior Subordinated
Debentures so redeemed at the redemption price; provided, that holders of trust
securities will be given not less than 20 nor more than 60 days' notice of the
redemption. If fewer than all of the outstanding trust securities are to be
redeemed, the trust securities will be redeemed proportionately. (Section 7.3
of the Amended Trust Agreement.)

Special Event Redemption

    Both a Tax Event and an Investment Company Act Event constitute Special
Events for purposes of the redemption provisions described in the preceding
paragraph.

    A Tax Event means that the Administrative Trustees have received an opinion
of independent tax counsel experienced in those matters to the effect that, as
a result of any amendment to, change or announced proposed change in:

 . the laws or regulations of the United States or any of its political
  subdivisions or taxing authorities, or

 . any official administrative pronouncement, action or judicial decision
  interpreting or applying those laws or regulations,

which amendment or change becomes effective or proposed change, pronouncement,
action or decision is announced on or after the date the Trust Preferred
Securities are issued and sold, there is more than an insubstantial risk that:

                                       21


 . the Trust is or within 90 days would be subject to U.S. federal income tax
  with respect to income accrued or received on the Junior Subordinated
  Debentures,

 . interest payable to the Trust on the Junior Subordinated Debentures is not or
  within 90 days would not be deductible, in whole or in part, by us for U.S.
  federal income tax purposes, or

 . the Trust is or within 90 days would be subject to a material amount of other
  taxes, duties or other governmental charges.

    Investment Company Event means that the Administrative Trustees have
received an opinion of a nationally recognized independent counsel to the
effect that, as a result of an amendment to or change in the Investment Company
Act or regulations thereunder on or after the date the Trust Preferred
Securities are issued and sold, there is more than an insubstantial risk that
the Trust is or will be considered an investment company and be required to be
registered under the Investment Company Act. (Section 1.1 of the Amended Trust
Agreement.)

Redemption Procedures

    The Trust may not redeem fewer than all the outstanding trust securities
unless all accrued and unpaid distributions have been paid on all trust
securities for all distribution periods terminating on or before the date of
redemption. If fewer than all of the outstanding trust securities are to be
redeemed, the trust securities will be redeemed proportionately.

    If the Trust gives a notice of redemption in respect of the trust
securities (which notice will be irrevocable), and if we have paid to the
Property Trustee a sufficient amount of cash in connection with the related
redemption or maturity of the Junior Subordinated Debentures, then, by 12:00
noon New York City time on the redemption date, the Property Trustee will
irrevocably deposit with the depositary funds sufficient to pay the applicable
redemption price and will give the depositary irrevocable instructions and
authority to pay the redemption price to the holders of the Trust Preferred
Securities, and the paying agent will pay the applicable redemption price to
the holders of the trust common securities by check. If notice of redemption
has been given and funds deposited as required, then, immediately before the
close of business on the date of the deposit, distributions will cease to
accrue and all rights of holders of Trust Preferred Securities called for
redemption will cease, except the right of the holders of the Trust Preferred
Securities to receive the redemption price but without interest on the
redemption price. If any date fixed for redemption of Trust Preferred
Securities is not a business day, then payment of the redemption price payable
on that date will be made on the next succeeding day that is a business day,
without any interest or other payment in respect of any such delay, except
that, if that business day falls in the next calendar year, payment will be
made on the immediately preceding business day. If payment of the redemption
price in respect of Trust Preferred Securities is improperly withheld or
refused and not paid either by the Trust or by us under the Guarantee,
distributions on the Trust Preferred Securities will continue to accrue at the
then applicable rate from the original redemption date to the date of payment,
in which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the redemption price.


                                       22


    Subject to the foregoing and applicable law, including, without limitation,
U.S. federal securities laws, we or our subsidiaries may at any time, and from
time to time, purchase outstanding Trust Preferred Securities by tender, in the
open market or by private agreement. (Section 7.4 of the Amended Trust
Agreement.)

Distribution of the Junior Subordinated Debentures

    We will have the right at any time to dissolve the Trust and, after
satisfaction of the liabilities of creditors of the Trust as provided by
applicable law, to cause Junior Subordinated Debentures to be distributed to
the holders of the Trust Preferred Securities in a total stated principal
amount equal to the total stated liquidation amount of the Trust Preferred
Securities then outstanding. Before any such dissolution, we will obtain any
required regulatory approvals. The right to dissolve the trust and distribute
the Junior Subordinated Debentures will be conditioned on our receipt of an
opinion rendered by an independent tax counsel that the distribution would not
result in the recognition of gain or loss for federal income tax purposes by
the holders. (Section 8.1 of the Amended Trust Agreement.)

Liquidation Distribution Upon Dissolution

    The amended trust agreement will state that the Trust will be dissolved:

 . upon our bankruptcy;

 . upon the filing of a certificate of dissolution or its equivalent with
  respect to us;

 . upon the filing of a certificate of cancellation with respect to the Trust
  after obtaining the consent of at least a majority in liquidation amount of
  the Trust Preferred Securities, voting together as a single class;

 . 90 days after the revocation of our charter, but only if the charter is not
  reinstated during that 90-day period;

 . upon the distribution of the related Junior Subordinated Debentures directly
  to the holders of the trust securities;

 . upon the redemption of all of the trust securities; or

 . upon entry of a court order for the dissolution of us or the Trust.
  (Section 8.1 of the Amended Trust Agreement.)

    Upon a dissolution, after the Trust pays all amounts owed to creditors, the
holders of the Trust Preferred Securities will be entitled to receive:

 . cash equal to the total liquidation amount of the Trust Preferred Security
  specified in an accompanying prospectus supplement, plus accumulated and
  unpaid distributions to the date of payment, or

 . Junior Subordinated Debentures in a total principal amount equal to the total
  liquidation amount of the Trust Preferred Securities.

    If the Trust cannot pay the full amount due on its trust securities because
insufficient assets are available for payment, then the amounts payable by the
Trust on its trust securities will be paid proportionately. However, if an
event of default under the related amended trust agreement occurs, the total
amounts due on the Trust Preferred Securities will be paid before any
distribution on the trust common securities. Under certain circumstances

                                       23


involving the dissolution of a Trust, subject to obtaining any required
regulatory approval, Junior Subordinated Debentures will be distributed to the
holders of the trust securities in liquidation of that Trust. (Section 8.2 of
the Amended Trust Agreement.)

Trust Enforcement Events

    An event of default under the Subordinated Indenture relating to the Junior
Subordinated Debentures will be an event of default under the amended trust
agreement (a Trust Enforcement Event). See DESCRIPTION OF DEBT SECURITIES--
EVENTS OF DEFAULT.

    In addition, the voluntary or involuntary dissolution, winding up or
termination of the Trust is also a Trust Enforcement Event, except in
connection with:

 . the distribution of the Junior Subordinated Debentures to holders of the
  trust securities of the Trust,

 . the redemption of all of the trust securities of the Trust, or

 . mergers, consolidations or amalgamations permitted by the amended trust
  agreement of the Trust.

    Under the amended trust agreement, the holder of the trust common
securities will be deemed to have waived any Trust Enforcement Event with
respect to the trust common securities until all Trust Enforcement Events with
respect to the Trust Preferred Securities have been cured, waived or otherwise
eliminated. Until all Trust Enforcement Events with respect to the Trust
Preferred Securities have been so cured, waived, or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the holders of
the Trust Preferred Securities and only the holders of the Trust Preferred
Securities will have the right to direct the Property Trustee with respect to
certain matters under the amended trust agreement and the Subordinated
Indenture. If any Trust Enforcement Event with respect to the Trust Preferred
Securities is waived by the holders of the Trust Preferred Securities as
provided in the amended trust agreement, under the amended trust agreement the
holders of trust common securities have agreed that the waiver also constitutes
a waiver of the Trust Enforcement Event with respect to the trust common
securities for all purposes under the amended trust agreement without any
further act, vote or consent of the holders of trust common securities.
(Section 2.6 of the Amended Trust Agreement.)

    We and the Administrative Trustees must file annually with the Property
Trustee a certificate evidencing compliance with all the applicable conditions
and covenants under the amended trust agreement. (Section 2.4 of the Amended
Trust Agreement.)

    Upon the occurrence of a Trust Enforcement Event the Property Trustee, as
the sole holder of the Junior Subordinated Debentures, will have the right
under the Subordinated Indenture to declare the principal of, interest and
premium, if any, on the Junior Subordinated Debentures to be immediately due
and payable.

    If the Property Trustee fails to enforce its rights under the amended trust
agreement or the Subordinated Indenture to the fullest extent permitted by law
and subject to the terms of the amended trust agreement and the Subordinated
Indenture,

                                       24


any holder of Trust Preferred Securities may sue us, or seek other remedies, to
enforce the Property Trustee's rights under the amended trust agreement or the
Subordinated Indenture without first instituting a legal proceeding against the
Property Trustee or any other person. If a Trust Enforcement Event occurs and
is continuing as a result of our failure to pay principal of or interest or
premium, if any, on the Junior Subordinated Debentures when payable, then a
holder of the Trust Preferred Securities may directly sue us or seek other
remedies, to collect its proportionate share of payments owned. See
RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES, THE GUARANTEE AND THE JUNIOR
SUBORDINATED DEBENTURES HELD BY THE TRUST.

Removal and Replacement of Trustees

    Only the holders of trust common securities have the right to remove or
replace the trustees of the Trust, except that while an event of default in
respect of the Junior Subordinated Debentures has occurred or is continuing,
the holders of a majority of the Trust Preferred Securities will have this
right. The resignation or removal of any trustee and the appointment of a
successor trustee will be effective only on the acceptance of appointment by
the successor trustee in accordance with the provisions of the amended trust
agreement. (Section 6.6 of the Amended Trust Agreement.)

Mergers, Consolidations or Amalgamations of the Trust

    The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other corporation or other body (each, a
Merger Event), except as described below. The Trust may, with the consent of a
majority of its Administrative Trustees and without the consent of the holders
of its trust securities, consolidate, amalgamate, merge with or into, or be
replaced by another trust, provided that the following conditions are met:

 . the successor entity either

  . assumes all of the obligations of the Trust relating to its trust
    securities, or

  . substitutes other securities for the trust securities that are
    substantially similar to the trust securities, so long as the successor
    securities rank the same as the trust securities for distributions and
    payments upon liquidation, redemption and otherwise;

 . we acknowledge a trustee of the successor entity who has the same powers and
  duties as the Property Trustee of the Trust, as the holder of the Junior
  Subordinated Debentures;

 . the Trust Preferred Securities are listed, or any successor securities will
  be listed, upon notice of issuance, on the same securities exchange or other
  organization that the Trust Preferred Securities are then listed;

 . the Merger Event does not cause the Trust Preferred Securities or successor
  securities to be downgraded by any nationally recognized rating agency;

 . the Merger Event does not adversely affect the rights, preferences and
  privileges of the holders of the trust securities or successor securities in
  any material way, other than with respect to any dilution of the holders'
  interest in the new entity;

                                       25


 . the successor entity has a purpose identical to that of the Trust;

 . before the Merger Event, we have received an opinion of counsel from a
  nationally recognized law firm stating that

  . the Merger Event does not adversely affect the rights of the holders of
    the Trust Preferred Securities or any successor securities in any
    material way, other than with respect to any dilution of the holders'
    interest in the new entity, and

  . following the Merger Event, neither the Trust nor the successor entity
    will be required to register as an investment company under the
    Investment Company Act; and

 . we guarantee the obligations of the successor entity under the successor
  securities in the same manner as in the Guarantee.

    In addition, unless all of the holders of the Trust Preferred Securities
and trust common securities approve otherwise, the Trust will not consolidate,
amalgamate, merge with or into, or be replaced by any other entity or permit
any other entity to consolidate, amalgamate, merge with or into, or replace it,
if, in the opinion of a nationally recognized tax counsel experienced in such
matters, the transaction would cause the Trust or the successor entity to be
classified other than as a grantor trust for U.S. federal income tax purposes.
(Section 3.15 of the Amended Trust Agreement.)

Voting Rights; Amendment of Trust Agreement

    The holders of Trust Preferred Securities have no voting rights except as
discussed under MERGERS, CONSOLIDATIONS OR AMALGAMATIONS OF THE TRUST AND
DESCRIPTION OF THE GUARANTEE--AMENDMENTS, and as otherwise required by law and
the amended trust agreement.

    The amended trust agreement may be amended if approved by a majority of the
Administrative Trustees of the Trust. However, if any proposed amendment
provides for, or the Administrative Trustees otherwise propose to effect,

 . any action that would adversely affect the powers, preferences or special
  rights of the trust securities, whether by way of amendment to the amended
  trust agreement or otherwise, or

 . the dissolution, winding-up or termination of the Trust other than under the
  terms of its amended trust agreement,

then the holders of the Trust Preferred Securities as a single class will be
entitled to vote on the amendment or proposal. In that case, the amendment or
proposal will only be effective if approved by at least a majority in
liquidation amount of the Trust Preferred Securities affected by the amendment
or proposal.

    No amendment may be made to the amended trust agreement if that amendment
would:

 . cause the Trust to be characterized as other than a grantor trust for U.S.
  federal income tax purposes;

 . reduce or otherwise adversely affect the powers of the Property Trustee; or

 . cause the Trust to be deemed to be an investment company which is required to
  be registered under the Investment

                                       26


  Company Act. (Section 11.1 of the Amended Trust Agreement.)

    The holders of a majority of the total liquidation amount of the Trust
Preferred Securities have the right to:

 . direct the time, method and place of conducting any proceeding for any remedy
  available to the Property Trustee; or

 . direct the exercise of any trust or power conferred upon the Property Trustee
  under the amended trust agreement, including the right to direct the Property
  Trustee, as the holder of the Junior Subordinated Debentures, to

 . exercise the remedies available under the Subordinated Indenture with respect
  to the Junior Subordinated Debentures,

 . waive any event of default under the Subordinated Indenture that is waivable,
  or

 . cancel an acceleration of the principal of the Junior Subordinated
  Debentures.

    In addition, before taking any of the foregoing actions, the Property
Trustee must obtain an opinion of counsel stating that, as a result of that
action, the Trust will continue to be classified as a grantor trust for U.S.
federal income tax purposes. (Section 7.5 of the Amended Trust Agreement.)

    As described in the form of amended trust agreement, the Property Trustee
may hold a meeting to have holders of Trust Preferred Securities vote on a
change or have them approve a change by written consent.

    If a vote by the holders of Trust Preferred Securities is taken or a
consent is obtained, any Trust Preferred Securities owned by us or any of our
affiliates will, for purposes of the vote or consent, be treated as if they
were not outstanding, which will have the following consequences:

 . we and any of our affiliates will not be able to vote on or consent to
  matters requiring the vote or consent of holders of Trust Preferred
  Securities; and

 . any Trust Preferred Securities owned by us or any of our affiliates will not
  be counted in determining whether the required percentage of votes or
  consents has been obtained. (Section 7.5 of the Amended Trust Agreement.)

Information Concerning the Property Trustee

    For matters relating to compliance with the Trust Indenture Act, the
Property Trustee will have all of the duties and responsibilities of an
indenture trustee under the Trust Indenture Act. The Property Trustee, other
than during the occurrence and continuance of a Trust Enforcement Event,
undertakes to perform only the duties that are specifically described in the
amended trust agreement and, upon a Trust Enforcement Event, must use the same
degree of care and skill as a prudent person would exercise or use in the
conduct of his or her own affairs. Subject to this provision, the Property
Trustee is under no obligation to exercise any of the powers given it by the
applicable amended trust agreement at the request of any holder of Trust
Preferred Securities unless it is offered reasonable security or indemnity
against the costs, expenses and liabilities that it might incur. However, the
holders of the Trust Preferred Securities will not be required to offer such an
indemnity where the holders, by

                                       27


exercising their voting rights, direct the Property Trustee to take any action
following a Trust Enforcement Event. (Section 3.9 of the Amended Trust
Agreement.)

Information Concerning the Administrative Trustees

    The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Trust in a way that:

 . will not cause it to be deemed to be an investment company required to be
  registered under the Investment Company Act;

 . will cause it to be classified as a grantor trust for U.S. federal income tax
  purposes; and

 . will cause the Junior Subordinated Debentures it holds to be treated as our
  indebtedness for U.S. federal income tax purposes.

    We and the Administrative Trustees are authorized to take any action, so
long as it is consistent with applicable law or the certificate of trust or
amended trust agreement, that we and the Administrative Trustees determine to
be necessary or desirable for those purposes. (Section 3.6 of the Amended Trust
Agreement.)

DESCRIPTION OF THE GUARANTEE

    We will execute the Guarantee from time to time for the benefit of the
holders of the Trust Preferred Securities.

    Bank One Trust Company, National Association will act as Guarantee Trustee
under the Guarantee. The Guarantee Trustee will hold the Guarantee for the
benefit of the holders of the Trust Preferred Securities.

    The following description of the Guarantee is only a summary. The form of
Guarantee is an exhibit to the registration statement.

General

    We will irrevocably and unconditionally agree under the Guarantee to pay
the Guarantee Payments, to the extent specified in the Guarantee, to the
holders of the Trust Preferred Securities, but only to the extent that the
Guarantee Payments are not paid by or on behalf of the related Trust. We are
required to pay the Guarantee Payments to the extent specified in the Guarantee
regardless of any defense, right of set-off or counterclaim that we may have or
may assert against any person. (Section 5.1 of the Guarantee.)

    The following payments and distributions on the Trust Preferred Securities
are Guarantee Payments:

 . any accrued and unpaid distributions required to be paid on the Trust
  Preferred Securities of the Trust, but only to the extent that the Trust has
  funds legally and immediately available for those distributions;

 . the redemption price for any Trust Preferred Securities that the Trust calls
  for redemption, including all accrued and unpaid distributions to the
  redemption date, but only to the extent that the Trust has funds legally and
  immediately available for the payment; and

 . upon a dissolution, winding-up or termination of the Trust, other than in
  connection with the distribution of Junior Subordinated Debentures to the
  holders of Trust Securities of the Trust or the redemption of all the Trust
  Preferred Securities of the Trust, the lesser of:

                                       28


  . the sum of the liquidation amount and all accrued and unpaid
    distributions on the Trust Preferred Securities of the Trust to the
    payment date, to the extent that the Trust has funds legally and
    immediately available for the payment; and

  . the amount of assets of the Trust remaining available for distribution to
    holders of the Trust Preferred Securities of the Trust in liquidation of
    the Trust. (Section 1.1 of the Guarantee.)

    We may satisfy our obligation to make a Guarantee Payment by making that
payment directly to the holders of the related Trust Preferred Securities or by
causing the Trust to make the payment to those holders. (Section 5.1 of the
Guarantee.)

    The Guarantee will be a full and unconditional guarantee, subject to
certain subordination provisions, of the Guarantee Payments with respect to the
related Trust Preferred Securities from the time of issuance of those Trust
Preferred Securities, except that the Guarantee will only apply to the payment
of distributions and other payments on the Trust Preferred Securities when the
Trust has sufficient funds legally and immediately available to make those
distributions or other payments.

    If we do not make the required payments on the Junior Subordinated
Debentures that the Property Trustee holds under a Trust, that Trust will not
make the related payments on its Trust Preferred Securities.

Subordination

    Our obligations under the Guarantee will be unsecured obligations of the
Company. Those obligations will rank:

 . subordinate and junior in right of payment to all of our other liabilities,
  other than obligations or liabilities that rank equal in priority or
  subordinate by their terms;

 . equal in priority with the Junior Subordinated Debentures that we may issue
  and similar guarantees; and

 . senior to our common stock. (Section 6.2 of the Guarantee.)

    The Guarantee will be a guarantee of payment and not of collection. This
means that the guaranteed party may institute a legal proceeding directly
against us, as guarantor, to enforce its rights under the Guarantee without
first instituting a legal proceeding against any other person or entity.
(Section 5.4 of the Guarantee.)

    The terms of the Trust Preferred Securities will provide that each holder
of the Trust Preferred Securities, by accepting those Trust Preferred
Securities, agrees to the subordination provisions and other terms of the
Guarantee.

Amendments

    We may amend the Guarantee without the consent of any holder of the Trust
Preferred Securities if the amendment does not materially and adversely affect
the rights of those holders. We may otherwise amend the Guarantee with the
approval of the holders of at least 50% of the outstanding Trust Preferred
Securities to which that Guarantee relates. (Section 9.2 of the Guarantee.)

                                       29


Termination

    The Guarantee will terminate and be of no further effect when:

 . the redemption price of the Trust Preferred Securities to which the Guarantee
  relates is fully paid;

 . we distribute the related Junior Subordinated Debentures to the holders of
  those Trust Preferred Securities; or

 . the amounts payable upon liquidation of the related Trust are fully paid.
  (Section 7.1 of the Guarantee.)

    The Guarantee will remain in effect or will be reinstated if at any time
any holder of the related Trust Preferred Securities must restore payment of
any sums paid to that holder with respect to those Trust Preferred Securities
or under the Guarantee.

Material Covenants

  We will covenant that, so long as any Trust Preferred Securities remain
outstanding, if there is an event of default under the Guarantee or the amended
trust agreement:

 . we will not make distributions related to our debt securities that rank
  equally with or junior to the Junior Subordinated Debentures, including any
  payment of interest, principal or premium, or repayments, repurchases or
  redemptions; and

 . we will not make distributions related to our capital stock, including
  dividends, redemptions, repurchases, liquidation payments, or guarantee
  payments. We may, however, make the following types of distributions:

  . dividends paid in common stock;

  . dividends in connection with the implementation of a shareholder rights
    plan;

  . payments to a trust holding securities of the same series under a
    guarantee; and

  . repurchases, redemptions or other acquisitions of shares of our capital
    stock in connection with any benefit plan or other similar arrangement
    with or for the benefit of employees, officers, directors or consultants.
    (Section 6.1 of the Guarantee.)

  Because we are a holding company that conducts all of our operations through
our subsidiaries, our ability to meet our obligations under the Guarantee is
dependent on the earnings and cash flows of those subsidiaries and the ability
of those subsidiaries to pay dividends or to advance or repay funds to us. The
Trust, as holder of the Guarantee and the Junior Subordinated Debentures will
generally have a junior position to claims of creditors of our subsidiaries,
including trade creditors, debtholders, secured creditors, taxing authorities,
guarantee holders and any preferred stockholders.

Events of Default

    An event of default will occur under the Guarantee if we fail to perform
any of our payment obligations under the Guarantee. The holders of a majority
of the Trust Preferred Securities of any series may waive any such event of
default and its consequences on behalf of all of the holders of the Trust
Preferred Securities of that series. (Section 2.6 of the Guarantee.) The
Guarantee Trustee is entitled to enforce the Guarantee for the benefit of the
holders of the Trust Preferred Securities of a series if

                                       30


an event of default occurs under the related Guarantee. (Section 3.1 of the
Guarantee.)

    The holders of a majority of the Trust Preferred Securities to which the
Guarantee relates have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee
with respect to that Guarantee or to direct the exercise of any trust or power
that the Guarantee Trustee holds under that Guarantee. Any holder of the
related Trust Preferred Securities may institute a legal proceeding directly
against us to enforce that holder's rights under the Guarantee without first
instituting a legal proceeding against the Guarantee Trustee or any other
person or entity. (Section 5.4 of the Guarantee.)

Concerning the Guarantee Trustee

    Bank One Trust Company, National Association is the Guarantee Trustee. It
is also the Property Trustee, the Subordinated Indenture Trustee and the Senior
Indenture Trustee. Bank One Delaware, Inc. is the Delaware trustee for the
Trust. We and certain of our affiliates maintain deposit accounts and banking
relationships with Bank One, N.A., an affiliate of Bank One Trust Company,
National Association. Bank One Trust Company, National Association also
performs agency functions with respect to other securities listed by our
affiliates. Bank One, NA and its affiliates have purchased, and are likely to
purchase in the future, our securities and securities of our affiliates.

    The Guarantee Trustee will perform only those duties that are specifically
set forth in the Guarantee unless an event of default under the Guarantee
occurs and is continuing. In case an event of default occurs and is continuing,
the Guarantee Trustee will exercise the same degree of care as a prudent
individual would exercise in the conduct of his or her own affairs. (Section
3.1 of the Guarantee.) Subject to those provisions, the Guarantee Trustee is
under no obligation to exercise any of its powers under the Guarantee at the
request of any holder of the related Trust Preferred Securities unless that
holder offers reasonable indemnity to the Guarantee Trustee against the costs,
expenses and liabilities which it might incur as a result. (Section 3.2 of the
Guarantee.)

AGREEMENT AS TO EXPENSES AND LIABILITIES

    We will enter into an Agreement as to Expenses and Liabilities under the
Trust Agreement. The Agreement as to Expenses and Liabilities will provide that
we will, with certain exceptions, irrevocably and unconditionally guarantee the
full payment of any indebtedness, expenses or liabilities of the Trust to each
person or entity to whom that Trust becomes indebted or liable. The exceptions
are the obligations of the Trust to pay to the holders of the related trust
common or other similar interests in that Trust the amounts due to the holders
under the terms of those trust common securities or those similar interests.

RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES, THE GUARANTEE AND THE JUNIOR
SUBORDINATED DEBENTURES HELD BY THE TRUST

    We will guarantee payments of distributions and redemption and liquidation
payments due on the Trust Preferred Securities, to the extent the trust has
funds available for the payments, to the extent described under DESCRIPTION OF
THE GUARANTEE. No single document executed by us in connection with the

                                       31


issuance of the Trust Preferred Securities will provide for our full,
irrevocable and unconditional guarantee of the Trust Preferred Securities. It
is only the combined operation of our obligations under the Guarantee, the
amended trust agreement and the Subordinated Indenture that has the effect of
providing a full, irrevocable and unconditional guarantee of the Trust's
obligations under the Trust Preferred Securities.

    As long as we make payments of interest and other payments when due on the
Junior Subordinated Debentures held by the Trust, those payments will be
sufficient to cover the payment of distributions and redemption and liquidation
payments due on the Trust Preferred Securities issued by the Trust, primarily
because:

 . the total principal amount of the Junior Subordinated Debentures will be
  equal to the sum of the total liquidation amount of the trust securities;

 . the interest rate and interest and other payment dates on the Junior
  Subordinated Debentures will match the distribution rate and distribution and
  other payment dates for the Trust Preferred Securities;

 . we will pay for any and all costs, expenses and liabilities of the Trust
  except its obligations under its Trust Preferred Securities; and

 . the amended trust agreement will provide that the Trust will not engage in
  any activity that is not consistent with the limited purposes of the Trust.

    If and to the extent that we do not make payments on the Junior
Subordinated Debentures, the Trust will not have funds available to make
payments of distributions or other amounts due on its Trust Preferred
Securities. In those circumstances, you will not be able to rely upon the
Guarantee for payment of these amounts. Instead, you may directly sue us or
seek other remedies to collect your proportionate share of payments owed. If
you sue us to collect payment, then we will assume your rights as a holder of
Trust Preferred Securities under the amended trust agreement to the extent we
make a payment to you in any such legal action.

ACCOUNTING TREATMENT

    The Trust will be treated as a subsidiary of ours for financial reporting
purposes. Accordingly, our consolidated financial statements will include the
accounts of the Trust. The Trust Preferred Securities, along with other trust
preferred securities that we guarantee on an equivalent basis, will be
presented as a separate line item in our consolidated balance sheets, and
appropriate disclosures about the Trust Preferred Securities, the Guarantee and
the Junior Subordinated Debentures will be included in the notes to the
consolidated financial statements. We will record distributions that the Trust
pays on the Trust Preferred Securities as an expense in our consolidated
statement of income.

PLAN OF DISTRIBUTION

    We may sell the offered securities (a) through agents; (b) through
underwriters or dealers; or (c) directly to one or more purchasers.

By Agents

    Offered securities may be sold through agents that we designate. The agents
agree to use their reasonable best efforts to solicit purchases for the period
of their appointment.

                                       32


By Underwriters

    If underwriters are used in the sale, the offered securities will be
acquired by the underwriters for their own account. The underwriters may resell
the securities in one or more transactions, including negotiated transactions,
at a fixed public offering price or at varying prices determined at the time of
sale. The obligations of the underwriters to purchase the securities will be
subject to certain conditions. The underwriters will be obligated to purchase
all the securities of the series offered if any of the securities are
purchased. Any initial public offering price and any discounts or concessions
allowed or re-allowed or paid to dealers may be changed from time to time.

Direct Sales

    We may also sell offered securities directly. In this case, no underwriters
or agents would be involved.

General Information

    Underwriters, dealers and agents that participate in the distribution of
the offered securities may be underwriters as defined in the Securities Act of
1933, and any discounts or commissions received by them from us and any profit
on the resale of the offered securities by them may be treated as underwriting
discounts and commissions under the Act. Any underwriters or agents will be
identified and their compensation described in a prospectus supplement.

    We may have agreements with the underwriters, dealers and agents to
indemnify them against certain civil liabilities, including liabilities under
the Act, or to contribute with respect to payments which the underwriters,
dealers or agents may be required to make.

    Underwriters, dealers and agents may engage in transactions with, or
perform services for, us or our subsidiaries in the ordinary course of their
businesses.

LEGAL OPINIONS

    McGuireWoods LLP, counsel to the Company, will issue an opinion about the
legality of the offered securities for us. As of December 20, 2000, partners of
McGuireWoods LLP owned less than one half of one percent of the common stock of
Dominion Resources, Inc. Certain matters relating to the formation of the Trust
and the issuance of the Trust Preferred Securities under Delaware law and the
Trust Agreement will be passed upon by Richards, Layton & Finger P.A., special
Delaware counsel to the Trust and the Company. Any underwriters will be advised
about other issues relating to any offering by their own legal counsel.
