                                 TRUST AGREEMENT

                          DOMINION CNG CAPITAL TRUST II



         THIS TRUST AGREEMENT is made as of March 28, 2002 (this "Trust
Agreement"), by and between Consolidated Natural Gas Company, a Delaware
corporation, as sponsor (the "Sponsor"), Bank One Delaware, Inc., a Delaware
corporation (the "Delaware Trustee") and G. Scott Hetzer (the "Administrative
Trustee" and together with the Delaware Trustee and any additional trustees
appointed under Section 10, the "Trustees"). The Sponsor and the Trustees hereby
agree as follows:

         1. The trust created hereby shall be known as "DOMINION CNG CAPITAL
TRUST II" (the "Trust") in which name the Trustee or the Sponsor, to the extent
provided herein, may conduct the business of the Trust, make and execute
contracts, and sue and be sued.

         2. The Sponsor hereby assigns, transfers, conveys and sets over to the
Trust the sum of ten dollars ($10.00). Such amount shall constitute the initial
trust estate. It is the intention of the parties hereto that the Trust created
hereby constitute a business trust under Chapter 38 of Title 12 of the Delaware
Code, 12 Del. C. ss. 3801, et seq. (the "Business Trust Act"), and that this
document constitute the governing instrument of the Trust. The Trustees are
hereby authorized and directed to execute and file a certificate of trust with
the Delaware Secretary of State in accordance with the provisions of the
Business Trust Act.

         3. The Sponsor and the Trustees will enter into an amended and restated
Trust Agreement or Declaration satisfactory to each such party to provide for
the contemplated operation of the Trust created hereby and the issuance of the
Preferred Securities and the Common Securities referred to therein. Prior to the
execution and delivery of such amended and restated Trust Agreement or
Declaration, the Trustees shall not have any duty or obligation hereunder or
with respect of the trust estate, except as otherwise required by applicable law
or as may be necessary to obtain prior to such execution and delivery any
licenses, consents or approvals required by applicable law or otherwise.
Notwithstanding the foregoing, the Trustees may take all actions deemed proper
as are necessary to effect the transactions contemplated herein.

         4. The Sponsor, as the sponsor of the Trust, is hereby authorized, in
its discretion, (i) to prepare and file with the Securities and Exchange
Commission (the "Commission") and to execute, in each case on behalf of the
Trust, (a) a Registration Statement (the "1933 Act Registration Statement"),
including all pre-effective and post-effective amendments thereto, relating to
the registration under the Securities Act of 1933, as amended (the "1933 Act"),
of the Preferred Securities of the Trust and (b) a Registration Statement on
Form 8-A (the "1934 Act Registration Statement"), including all pre-effective
and post-effective amendments thereto, relating to the
<PAGE>

registration of the Preferred Securities of the Trust under the Securities
Exchange Act of 1934, as amended; (ii) if and at such time as determined by the
Sponsor, to file with the New York Stock Exchange or any other exchange or the
National Association of Securities Dealers (each, an "Exchange"), and execute on
behalf of the Trust one or more listing applications and all other applications,
statements, certificates, agreements and other instruments as shall be necessary
or desirable to cause the Preferred Securities of the Trust to be listed on any
of the Exchanges; (iii) to negotiate, execute, deliver and perform on behalf of
the Trust an underwriting agreement with one or more underwriters relating to
the offering of the Preferred Securities of the Trust; and (iv) to file and
execute on behalf of the Trust, such applications, reports, surety bonds,
irrevocable consents, appointments of attorney for service of process and other
papers and documents that shall be necessary or desirable to register the
Preferred Securities of the Trust under the securities or "Blue Sky" laws of
such jurisdictions as the Sponsor, on behalf of the Trust, may deem necessary or
desirable.

         In the event that any filing referred to in this Section 4 is required
by the rules and regulations of the Commission, any Exchange or state securities
or "Blue Sky" laws to be executed on behalf of the Trust by the Trustees, the
Trustees, in their capacities as trustees of the Trust, are hereby authorized to
join in any such filing and to execute on behalf of the Trust any and all of the
foregoing, it being understood that the Trustees, in their capacities as
trustees of the Trust, shall not be required to join in any such filing or
execute on behalf of the Trust any such document unless required by the rules
and regulations of the Commission, an Exchange or state securities or "Blue Sky"
laws.

         5.   (a) The Trustees (the "Fiduciary Indemnified Persons") shall not
be liable, responsible or accountable in damages or otherwise to the Trust, the
Sponsor, the Trustees or any holder of the Trust securities (the Trust, the
Sponsor and any holder of the Trust securities being a "Covered Person") for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by the Fiduciary Indemnified Persons in good faith on behalf of the
Trust and in a manner the Fiduciary Indemnified Persons reasonably believed to
be within the scope of authority conferred on the Fiduciary Indemnified Persons
by this Agreement or by law, except that the Fiduciary Indemnified Persons shall
be liable for any such loss, damage or claim incurred by reason of the Fiduciary
Indemnified Person's negligence or willful misconduct with respect to such acts
or omissions.

              (b) The Fiduciary Indemnified Persons shall be fully protected in
relying in good faith upon the records of the Trust and upon such information,
opinions, reports or statements presented to the Trust by any person as to
matters the Fiduciary Indemnified Persons reasonably believes are within such
other person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which distributions to holders of Trust securities might properly be
paid.

         6.  The Sponsor agrees to the fullest extent permitted by applicable
law,

              (a) to indemnify and hold harmless each Fiduciary Indemnified
Persons, or any of its officers, directors, shareholders, employees,
representatives or agents, from and against any loss, damage, liability, tax,
penalty, expense or claim of any kind or nature whatsoever incurred by the
Fiduciary Indemnified Persons by reason of the creation, operation or
termination of the Trust in a manner the Fiduciary Indemnified Persons
reasonably believed to be within the scope of authority conferred on the
Fiduciary Indemnified Persons by this Trust Agreement, except that no Fiduciary
Indemnified Persons shall be entitled to be indemnified in respect of any loss,
damage or claim incurred by the Fiduciary Indemnified Persons by reason of
negligence or willful misconduct with respect to such acts or omissions; and

              (b) to advance expenses (including legal fees) incurred by a
Fiduciary Indemnified Person in defending any claim, demand, action, suit or
proceeding shall, from time to time, prior to the final disposition of such
claim, demand, action, suit or proceeding, upon receipt by the Trust of an
undertaking by or on behalf of such Fiduciary Indemnified Persons to repay such
amount if it shall be determined that such Fiduciary Indemnified Person is not
entitled to be indemnified as authorized in the preceding subsection.

         7. The provisions of Section 6 shall survive the termination of this
Trust Agreement or the earlier resignation or removal of the Fiduciary
Indemnified Persons.

         8. The Trust may terminate without issuing any Trust securities at the

increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware. Subject to the foregoing, the Sponsor is entitled to
appoint or remove without cause any trustee of the Trust at any time. Any
trustee of the Trust may resign upon thirty days' prior notice to the Sponsor.
