                                 TRUST AGREEMENT
                                       OF
                          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,
<PAGE>

              (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
election of the Sponsor.

         9. This Trust Agreement may be executed in one or more counterparts.

         10. The number of trustees of the Trust initially shall be two and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Sponsor which may
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.

         11. The Delaware Trustee shall not have any of the powers or duties of

purpose of fulfilling the requirements of ss. 3807(a) of the Business Trust Act

          have the right to direct the Property Trustee in accordance with the
          terms of the Securities. The foregoing provisions of this Section
          2.6(b) shall be in lieu of Sections 316(a)(1)(A) and 316(a)(1)(B) of

          from this Trust Agreement and the Securities, as permitted by the
          Trust Indenture Act. Subject to the foregoing provisions of this
          Section 2.6(b), upon such cure, waiver or other elimination, any such
          default shall cease to exist and any Trust Enforcement Event with
          respect to the Common Securities arising therefrom shall be deemed to
          have been cured for every purpose of this Trust Agreement, but no such
          waiver shall extend to any subsequent or other Trust Enforcement Event
          with respect to the Common Securities or impair any right consequent
          thereon.

     (c)  A waiver of an Indenture Event of Default by the Property Trustee at
the direction of the Holders of the Trust Preferred Securities constitutes a
waiver of the corresponding Trust

Enforcement Event with respect to the Trust Preferred Securities under this
Trust Agreement. The foregoing provisions of this Section 2.6(c) shall be in
lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Trust Agreement and the Securities, as permitted by the Trust Indenture Act.

Trust Enforcement Event actually known to a Responsible Officer of the Property
Trustee, transmit by mail, first class postage prepaid, to the Holders of the
Securities, notices of all such defaults with respect to the Securities, unless
such defaults have been cured before the giving of such notice (the term
"defaults" for the purposes of this Section 2.7(a) and (b) being hereby defined
to be an Indenture Event of Default, not including any periods of grace provided
for therein and irrespective of the giving of any notice provided therein);
provided that, except for a default in the payment of principal of (or premium,
if any) or interest on any of the Debentures, the Property Trustee shall be
protected in withholding such notice if and so long as a Responsible Officer of
the Property Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders of the Securities.

     (b)  The Property Trustee shall not be deemed to have knowledge of any
default except:

                    (i)    a default under Sections 6.1(a) and (b) of the
          Indenture; or

                    (ii)   any default as to which the Property Trustee shall
          have received written notice pursuant to Section 3.10(a)(xiv) or of
          which a Responsible Officer of the Property Trustee charged with the
          administration of this Trust Agreement shall have actual knowledge.

     Section 3.8    Powers and Duties of the Property Trustee.
                    -----------------------------------------

     (a)  The legal title to the Debentures shall be owned by and held of record
in the name of the Property Trustee for the benefit of the Trust and the Holders
of the Securities. The right, title and interest of the Property Trustee to the
Debentures shall vest automatically in each Person who may hereafter be
appointed as Property Trustee in accordance with Section 6.6. Such vesting and
cessation of title shall be effective whether or not conveyancing documents with
regard to the Debentures have been executed and delivered.

     (b)  The Property Trustee shall not transfer its right, title and interest
in the Debentures to the Administrative Trustees or to the Delaware Trustee (if
the Property Trustee does not also act as Delaware Trustee).

     (c)  The Property Trustee shall:

                                      17
<PAGE>

               (i)     establish and maintain a segregated non-interest bearing
          trust account (the "Property Account") in the name of and under the
          exclusive control of the Property Trustee on behalf of the Holders of
          the Securities and, upon the receipt of payments of funds made in
          respect of the Debentures held by the Property Trustee, deposit such
          funds into the Property Account and make payments to the Holders of
          the Trust Preferred Securities and Holders of the Common Securities
          from the Property Account in accordance with Section 7.2. Funds in the
          Property Account shall be held uninvested until disbursed in
          accordance with this Trust Agreement. The Property Account shall be an
          account that is maintained with a banking institution the rating on
          whose long-term unsecured indebtedness is at least equal to the rating
          assigned to the Trust Preferred Securities by a "nationally recognized
          statistical rating organization", within the meaning of Rule 436(g)(2)
          under the Securities Act;

               (ii)    engage in such ministerial activities as shall be
          necessary or appropriate to effect the redemption of the Trust
          Preferred Securities and the Common Securities to the extent the
          Debentures are redeemed or mature; and

               (iii)   upon written notice of distribution issued by the
          Administrative Trustees in accordance with the terms of the
          Securities, engage in such ministerial activities as so directed and
          as shall be necessary or appropriate to effect the distribution of the
          Debentures to Holders of Securities upon the occurrence of a Special
          Event.

     (d)  The Property Trustee shall take all actions and perform such duties as
may be specifically required of the Property Trustee pursuant to the terms of
this Trust Agreement and the Securities.

     (e)  Subject to Section 3.9(a) the Property Trustee may take any Legal
Action which arises out of or in connection with a Trust Enforcement Event of
which a Responsible Officer of the Property Trustee has actual knowledge or the
Property Trustee's duties and obligations under this Trust Agreement or the
Trust Indenture Act; provided, however, if the Property Trustee fails to enforce
its rights under this Trust Agreement or the Indenture to the fullest extent
permitted by law and subject to the terms of this Trust Agreement and the
Indenture, then a Holder of Trust Preferred Securities may directly institute a
proceeding against the Debenture Issuer to enforce the Property Trustee's rights
under this Trust Agreement or the Indenture without first instituting a legal
proceeding against the Property Trustee or any other person; provided, further,
that if a Trust Enforcement Event has occurred and is continuing and such event
is attributable to the failure of the Debenture Issuer to pay interest,
principal or other required payments on the Debentures on the date such
interest, principal or other required payments are otherwise payable (or in the
case of redemption, on the redemption date), then a Holder of Trust Preferred
Securities may directly institute a proceeding against the Debenture Issuer for
enforcement of payment to such Holder of the principal of or interest on
Debentures having a principal amount equal to the aggregate Liquidation Amount
of the Trust Preferred Securities of such Holder (a "Direct Action") on or after
the respective due date specified in the Debentures. Notwithstanding anything to
the contrary in this Trust Agreement or the Indenture, the Debenture Issuer
shall have the right to set-off any payment it is otherwise required to make
under the Indenture in
                                       18
<PAGE>

respect of any Trust Preferred Security to the extent the Debenture Issuer has
heretofore made, or is currently on the date of such payment making, a payment
under the Guarantee relating to such Trust Preferred Security or under Section
6.5 of the Indenture.

       (f)    The Property Trustee shall continue to serve as a Trustee until
either:

                     (i)    the Trust has been completely liquidated and the
              proceeds of the liquidation distributed to the Holders of
              Securities pursuant to the terms of the Securities; or

                     (ii)   a Successor Property Trustee has been appointed and
              has accepted that appointment in accordance with Section 6.6.

       (g)    The Property Trustee shall have the legal power to exercise all of
the rights, powers and privileges of a holder of Debentures under the Indenture
and, if a Trust Enforcement Event actually known to a Responsible Officer of the
Property Trustee occurs and is continuing, the Property Trustee may, for the
benefit of Holders of the Securities, enforce its rights as holder of the
Debentures subject to the rights of the Holders pursuant to this Trust Agreement
and the terms of the Securities.

       (h)    Subject to this Section 3.8, the Property Trustee shall have none
of the duties, liabilities, powers or the authority of the Administrative
Trustees set forth in Section 3.6.

       The Property Trustee shall exercise the powers set forth in this Section
3.8 in a manner that is consistent with the purposes and functions of the Trust
set out in Section 3.3, and the Property Trustee shall have no power to, and
shall not, take any action that is inconsistent with the purposes and functions
of the Trust set out in Section 3.3.

                     ---------------------------------------------------
                     Trustee.
                     -------

       (a)    The Property Trustee, before the occurrence of any Trust
Enforcement Event and after the curing of all Trust Enforcement Events that may
have occurred, shall undertake to perform only such duties as are specifically
set forth in this Trust Agreement and no implied covenants shall be read into
this Trust Agreement against the Property Trustee. In case a Trust Enforcement
Event has occurred (that has not been cured or waived pursuant to Section 2.6)
of which a Responsible Officer of the Property Trustee has actual knowledge, the
Property Trustee shall exercise such of the rights and powers vested in it by
this Trust Agreement, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

       (b)    No provision of this Trust Agreement shall be construed to relieve
the Property Trustee from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that:

                     (i)    prior to the occurrence of a Trust Enforcement Event
              and after the curing or waiving of all such Trust Enforcement
              Events that may have occurred:

                     Trustee shall be determined solely by the express
                     provisions of this Trust Agreement and the Property Trustee
                     shall not be liable except for the performance of such
                     duties and obligations as are specifically set forth in
                     this Trust Agreement, and no implied covenants or
                     obligations shall be read into this Trust Agreement against
                     the Property Trustee; and

                            (B) in the absence of bad faith on the part of the
                     Property Trustee, the Property Trustee may conclusively
                     rely, as to the truth of the statements and the correctness
                     of the opinions expressed therein, upon any certificates or
                     opinions furnished to the Property Trustee and conforming
                     to the requirements of this Trust Agreement; but in the
                     case of any such certificates or opinions that by any
                     provision hereof are specifically required to be furnished
                     to the Property Trustee, the Property Trustee shall be
                     under a duty to examine the same to determine whether or
                     not they conform to the requirements of this Trust
                     Agreement;

                     (ii)   the Property Trustee shall not be liable for any
              error of judgment made in good faith by a Responsible Officer of
              the Property Trustee, unless it shall be proved that the Property
              Trustee was negligent in ascertaining the pertinent facts;

                     (iii)  the Property Trustee shall not be liable with
              respect to any action taken or omitted to be taken by it, in good
              faith in accordance with the direction of the Holders of not less
              than a Majority in Liquidation Amount of the Securities relating
              to the time, method and place of conducting any proceeding for any
              remedy available to the Property Trustee, or exercising any trust
              or power conferred upon the Property Trustee under this Trust
              Agreement;

                     (iv)   no provision of this Trust Agreement shall require
              the Property Trustee to expend or risk its own funds or otherwise
              incur personal financial liability in the performance of any of
              its duties or in the exercise of any of its rights or powers, if
              it shall have reasonable grounds for believing that the repayment
              of such funds or liability is not reasonably assured to it under
              the terms of this Trust Agreement or indemnity reasonably
              satisfactory to the Property Trustee against such risk or
              liability is not reasonably assured to it;

                     (v)    the Property Trustee's sole duty with respect to the
              custody, safe-keeping and physical preservation of the Debentures
              and the Property Account shall be to deal with such property in a
              similar manner as the Property Trustee deals with similar property
              for its own account, subject to the protections and limitations on
              liability afforded to the Property Trustee under this Trust
              Agreement and the Trust Indenture Act;

                     (vi)   the Property Trustee shall have no duty or liability
              for or with respect to the value, genuineness, existence or
              sufficiency of the Debentures or

                                       20

              the payment of any taxes or assessments levied thereon or in
              connection therewith;

                     (vii)  the Property Trustee shall not be liable for any
              interest on any money received by it except as it may otherwise
              agree with the Sponsor. Money held by the Property Trustee need
              not be segregated from other funds held by it except in relation
              to the Property Account maintained by the Property Trustee
              pursuant to Section 3.8(c)(i) and except to the extent otherwise
              required by law; and

                     (viii) the Property Trustee shall not be responsible for
              monitoring the compliance by the Administrative Trustees or the
              Sponsor with their respective duties under this Trust Agreement,
              nor shall the Property Trustee be liable for any default or
              misconduct of the Administrative Trustees or the Sponsor.

                     (iii)  whenever in the administration of this Trust
              Agreement, the Property Trustee shall deem it desirable that a
              matter be proved or established before taking, suffering or
              omitting any action hereunder, the Property Trustee (unless other
              evidence is herein specifically prescribed) may, in the absence of
              bad faith on its part, request and conclusively rely upon an
              Officers' Certificate which, upon receipt of such request, shall
              be promptly delivered by the Sponsor or the Administrative
              Trustees;

                     (iv)   the Property Trustee shall have no duty to see to

              choice or other experts and the advice or opinion of such counsel
              and experts with respect to legal matters or advice within the

              any time to seek instructions concerning the administration of
              this Trust Agreement from any court of competent jurisdiction;

              exercise any of the rights or powers vested in it by this Trust

              indemnity, reasonably satisfactory to the Property Trustee,
              against the costs, expenses (including reasonable attorneys' fees
              and expenses and the expenses of the Property Trustee's agents,
              nominees or custodians) and liabilities that might be incurred by

              reasonable advances as may be requested by the Property Trustee;
              provided that, nothing contained in this Section 3.10(a) shall be
              taken to relieve the Property Trustee, upon the occurrence of a
              Trust Enforcement Event, of its obligation to exercise the rights
              and powers vested in it by this Trust Agreement in the manner
              provided by Section 3.9(a);

                     (vii)  the Property Trustee shall not be bound to make any
              investigation into the facts or matters stated in any resolution,
              certificate, statement, instrument, opinion, report, notice,
              request, direction, consent, order, bond, debenture, note, other
              evidence of indebtedness or other paper or document, but the

                     (viii) the Property Trustee may execute any of the trusts
              or powers hereunder or perform any duties hereunder either
              directly or by or through agents, custodians, nominees or

              any misconduct or negligence on the part of any agent or attorney
              appointed with due care by it hereunder;

                     (ix)   any action taken by the Property Trustee or its
              agents hereunder shall bind the Trust and the Holders of the
              Securities, and the signature of the Property Trustee or its
              agents alone shall be sufficient and effective to perform any such
              action and no third party shall be required to inquire as to the
              authority of the Property Trustee to so act or as to its
              compliance with any of the terms and provisions of this Trust
              Agreement, both of which shall be conclusively evidenced by the
              Property Trustee's or its agent's taking such action;

              Agreement the Property Trustee shall deem it desirable to receive
              instructions with respect to enforcing any remedy or right or
              taking any other action hereunder, the Property Trustee (i) may
              request instructions from the Holders of the Securities which
              instructions may only be given by the Holders of the same
              proportion in Liquidation Amount of the Securities as would been
              entitled to direct the Property Trustee under the terms of the
              Securities in respect of such remedy, right or

                                       22
<PAGE>

              action, (ii) may refrain from enforcing such remedy or right or
              taking such other action until such instructions are received, and
              (iii) shall be protected in conclusively relying on or acting in
              or accordance with such instructions;

                     (xi)   except as otherwise expressly provided by this Trust
              Agreement, the Property Trustee shall not be under any obligation
              to take any action that is discretionary under the provisions of
              this Trust Agreement;

                     (xii)  the Property Trustee shall not be personally liable
              for the payment of any indebtedness or expenses of the Trust or be
              liable for the breach or failure of any obligation,
              representation, warranty or covenant made or undertaken by the
              Trust under this Trust Agreement, except if such breach or failure
              is due to any gross negligence or willful misconduct of the
              Property Trustee.;

                     (xiii) without prejudice to any other rights available to
              the Property Trustee under applicable law, when the Property
              Trustee incurs expenses or renders services in connection with a
              bankruptcy, such expenses (including the reasonable fees and
              expenses of its counsel) and the compensation for such services
              are intended to constitute expenses of administration under any
              bankruptcy law or law relating to creditors rights generally;

                     (xiv)  the Property Trustee shall not be charged with
              knowledge of a Trust Enforcement Event unless a Responsible
              Officer of the Property Trustee obtains actual knowledge of such
              event or the Property Trustee receives written notice of such
              event from Holders holding more than a Majority in Liquidation
              Amount of the Trust Preferred Securities; and

       (b)    No provision of this Trust Agreement shall be deemed to impose any
duty or obligation on the Property Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

       Section 3.15  Mergers.
                     -------

       (a)    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 Person, except as described in Section
3.15(b) and (c) or Section 8.2.

       (b)    The Trust may, at the request of the Sponsor and with the consent
of the Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees and without the consent of the Holders of the
Securities, the Delaware Trustee or the Property Trustee, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties substantially as an entirety to a trust organized as such under
the laws of any State; provided, that:

                     (i)    if the Trust is not the successor, such successor
              entity (the "Successor Entity") either:

                            (A) expressly assumes all of the obligations of the
                     Trust with respect to the Securities; or

                                       24
<PAGE>

                            (B) substitutes for the Trust Preferred Securities
                     other securities having substantially the same terms as the
                     Trust Preferred Securities (the "Successor Securities") so
                     long as the Successor Securities rank the same as the Trust
                     Preferred Securities rank in priority with respect to
                     Distributions and payments upon liquidation, redemption and
                     otherwise;

                     (ii)   if the Trust is not the successor Entity, the
              Sponsor expressly appoints a trustee of such Successor Entity that
              possesses the same powers and duties as the Property Trustee as
              the holder of the Debentures;

                     (iii)  the Trust Preferred Securities or any Successor
              Securities are listed, or any Successor Securities will be listed
              upon notification of issuance, on any national securities exchange
              or with any other or organization on which the Trust Preferred
              Securities are then listed or quoted;

                     (iv)   such merger, consolidation, amalgamation,
              replacement, conveyance, transfer or lease does not cause the
              Trust Preferred Securities (including any Successor Securities) to
              be downgraded by any nationally recognized statistical rating
              organization;

                     (v)    such merger, consolidation, amalgamation,
              replacement, conveyance, transfer or lease does not adversely
              affect the rights, preferences and privileges of the Holders of
              the Trust Preferred Securities (including any Successor
              Securities) in any material respect, other than with respect to
              any dilution of the Holders' interest in the new entity;

                     (vi)   such Successor Entity has a purpose substantially
              identical to that of the Trust;

                     (vii)  prior to such merger, consolidation, amalgamation,
              replacement, conveyance, transfer or lease the Sponsor has
              received an opinion of independent counsel to the Trust
              experienced in such matters to the effect that:

                            (A) such merger, consolidation, amalgamation,
                     replacement, conveyance, transfer or lease does not
                     adversely affect the rights, preferences and privileges of
                     the Holders of the Trust Preferred Securities (including
                     any Successor Securities) in any material respect, other
                     than with respect to any dilution of the Holders' interest
                     in the new entity;

                            (B) following such merger, consolidation,
                     amalgamation, replacement, conveyance, transfer or lease
                     neither the Trust nor the Successor Entity will be required
                     to register as an Investment Company; and

                            (C) following such merger, consolidation,
                     amalgamation or replacement, the Trust (or the Successor
                     Entity) will continue to be classified as a grantor trust
                     for United States federal income tax purposes;

                                       25
<PAGE>

                     (viii) the Sponsor or any permitted successor or assignee
              owns all of the common securities and guarantees the obligations
              of such Successor Entity under the Successor Securities at least
              to the extent provided by the Guarantee; and

                     (ix)   such Successor Entity expressly assumes all of the
              obligations of the Trust with respect to the Trustees.

       (c)    Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in aggregate Liquidation Amount of the
Securities, 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 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, such consolidation, amalgamation,
merger, replacement, conveyance, transfer or lease would cause the Trust or
Successor Entity to be classified as other than a grantor trust for United
States federal income tax purposes and each Holder of the Securities not to be
treated as owning an undivided interest in the Debentures.

       Section 3.16  Property Trustee May File Proofs of Claim. In case of the
                     -----------------------------------------
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Trust or any other obligor upon the Securities or the
property of the Trust or of such other obligor or their creditors, the Property
Trustee (irrespective of whether any Distributions on the Securities shall then
be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Property Trustee shall have made any demand on the
Trust for the payment of any past due Distributions) shall be entitled and
empowered, to the fullest extent permitted by law, by intervention in such
proceeding or otherwise:

       (a)    to file and prove a claim for the whole amount of any
Distributions owing and unpaid in respect of the Securities (or, if the
Securities are original issue discount Securities, such portion of the
Liquidation Amount as may be specified in the terms of such Securities) and to
file such other papers or documents as may be necessary or advisable in order to
have the claims of the Property Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel) and of the Holders allowed in such judicial proceeding; and

       (b)    to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Property Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

       Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement

                                       26

adjustment or compensation affecting the Securities or the rights of any Holder
thereof or to authorize the Property Trustee to vote in respect of the claim of
any Holder in any such proceeding.

          has accepted such appointment by instrument executed by such Successor
          Property Trustee and delivered to the Trust, the Sponsor and the
          resigning Property Trustee; or

                  (B)  until the assets of the Trust have been completely

     Trustee shall be effective until a Successor Delaware Trustee has been

     resigning Delaware Trustee.

    (d)   The Holders of the Common Securities shall use their best efforts to

Delaware Trustee, as applicable. Such court may thereupon, after prescribing
such notice, if any, as it may deem proper, appoint a Successor Property Trustee
or Successor Delaware Trustee, as the case may be.

     (f)  No Property Trustee or Delaware Trustee shall be liable for the acts
or omissions to act of any Successor Property Trustee or Successor Delaware
Trustee, as the case may be.

                  ------------------------
for any reason and the number of Trustees is not reduced pursuant to Section
6.1, or if the number of Trustees is increased pursuant to Section 6.1, a
vacancy shall occur. A resolution certifying the existence of such vacancy by
the Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees shall be conclusive evidence of the existence of such
vacancy. The vacancy shall be filled with a Trustee appointed in accordance with

                  -------------------

terminate the Trust. Whenever a vacancy in the number of Administrative Trustees
shall occur, until such vacancy is filled by the appointment of an

Trustees in office, regardless of their number, shall have all the powers
granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Trust Agreement.

Trustee. Regular meetings of the Administrative Trustees may be held at a time
and place fixed by resolution of the Administrative Trustees. Notice of any in-
person meetings of the Administrative Trustees shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 48 hours before such meeting. Notice of any
telephonic meetings of the Administrative Trustees shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 24 hours before a meeting. Notices shall
contain a brief statement of the time, place and anticipated purposes of the
meeting. The presence (whether in person or by telephone) of an Administrative
Trustee at a meeting shall constitute a waiver of notice of such meeting except
where an Administrative Trustee attends a meeting for the express purpose of
objecting to the transaction of any activity on the ground that the meeting has
not been lawfully called or convened. Unless provided otherwise in this Trust
Agreement, any action of the Administrative Trustees may be taken at a meeting
by vote of a majority of the Administrative Trustees present (whether in person
or by telephone) and eligible to vote with respect to such matter, provided that
a Quorum is present, or without a meeting by the unanimous written consent of
the Administrative Trustees. In the event there is only one Administrative
Trustee, any and all action of such Administrative Trustee shall be evidenced by
a written consent of such Administrative Trustee.

     Section 6.10  Delegation of Power.
                   -------------------

     (a)     Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any natural person over the age of 21 his, her
or its power for the purpose of executing any documents contemplated in Section

to time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

     Section 6.11  Merger, Conversion, Consolidation or Succession to Business.
                   -----------------------------------------------------------
Any corporation into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with such Trustee may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of such Trustee shall be the successor of such Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the

          to this Trust Agreement, with such changes and additions thereto or

          an initial aggregate Liquidation Amount with respect to the assets of
          the Trust of ___________________________________________ dollars
          ($____________). The Common Securities and any subsequent Tranches

          "Dominion CNG Capital Trust II ___% Common Securities" (the "Common
          Securities" and, together with the Trust Preferred Securities, the
          "Securities"). The Common Security Certificates evidencing the Common

          Holders having an aggregate principal amount equal to the aggregate
          Liquidation Amount of such Tranches of Securities.

     (b)  Payment of Distributions on, and payment of the Redemption Price upon
a redemption of, the Trust Preferred Securities and the Common Securities, as
applicable, shall be made Pro Rata based on the Liquidation Amount of such Trust
Preferred Securities and Common Securities; provided, however, that if on any
date on which amounts payable on distribution or redemption, an Indenture Event
of Default shall have occurred and be continuing, no payment of any Distribution
on, or Redemption Price of, any of the Common Securities, and no other payment
on account of the redemption, liquidation or other acquisition of such Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions on all of the outstanding Trust Preferred Securities for

Administrative Trustee. Such signature shall be the manual or facsimile
signature of any present or any future Administrative Trustee. In case an
Administrative Trustee of the Trust who shall have signed any of the
Certificates shall cease to be such an Administrative Trustee before the
Certificates so signed shall be delivered by the Trust, such Certificates
nevertheless may be delivered as though the person who signed such Certificates
had not ceased to be such an Administrative Trustee; and any Certificate may be
signed on behalf of the Trust by any person who, at the actual date of execution
of such Certificate, shall be an Administrative Trustee of the Trust, although
at the date of the execution and delivery of the Trust Agreement such person was
not such an Administrative Trustee. Certificates shall be printed, lithographed
or engraved or may be produced in any other manner as is reasonably acceptable
to the Administrative Trustees, as evidenced by an Administrative Trustee's
execution thereof, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements as the
Administrative Trustees may deem appropriate, or as may be required to comply
with any law or with any rule or regulation of any stock exchange on which
Securities may be listed, or to conform to usage.

     A Certificate representing Trust Preferred Securities shall not be valid
until authenticated by the manual signature of an authorized officer of the
Property Trustee. Such signature shall be conclusive evidence that such
Certificate has been authenticated under this Trust Agreement.

     The Trust Preferred Security Certificates shall be dated their date of
authentication.

     Upon a written order of the Trust signed by one Administrative Trustee,
the Property Trustee shall (i) concurrently with the initial issuance of the
Securities, authenticate the

                                      34
<PAGE>

Certificates representing Trust Preferred Securities for original issue and (ii)
concurrently with each periodic issuance of Tranches, evidence the current
number of outstanding securities by endorsing Schedule A to each Certificate..

     The Property Trustee may appoint an authenticating agent acceptable to the
Trust to authenticate Certificates. An authenticating agent may authenticate
Certificates whenever the Property Trustee may do so. Each reference in this
Trust Agreement to authentication by the Property Trustee includes
authentication by such agent. An authenticating agent has the same rights as the
Property Trustee to deal with the Sponsor or an Affiliate of the Sponsor.

     (d)  The consideration received by the Trust for each issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

     (e)  Except to the extent set forth in Section 9.1(b), upon each issuance
of the Securities as provided in this Trust Agreement, the Securities so issued
shall be deemed to be validly issued, fully paid and non-assessable undivided
beneficial ownership interests in the assets of the Trust.

     (f)  Every Person, by virtue of having become a Holder or a Trust Preferred
Security Beneficial Owner in accordance with the terms of this Trust Agreement,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by, this Trust Agreement and the terms of the Securities, the
Guarantee, the Indenture and the Debentures.

     (g)  The holders of the Securities shall have no preemptive or similar
rights.

     (h)  To the extent the Trust issues additional Tranches, the Property
Trustee shall (i) increase the number of Securities evidenced by each
Certificate by appropriate endorsement on Schedule A to each Certificate and
(ii) instruct the Depositary to credit the account of the purchaser of the
Tranche of Trust Preferred Securities.

     Section 7.2  Distributions.
                  -------------

     (a)   Holders of Securities shall be entitled to receive cumulative cash
Distributions at the rate per annum of ___% of the stated Liquidation Amount of
$__ per Security. The amount of Distributions payable for any period shall be
computed on the basis of a 360-day year of twelve 30-day months. The amount of
Distributions payable for any period shorter than a full [quarterly]
distribution period shall be computed on the basis of a 30-day month and for
periods of less than a month, the actual number of days elapsed per 30-day
month. Subject to Section 7.1(b), Distributions shall be made on the Trust
Preferred Securities and the Common Securities on a Pro Rata basis. Unless the
Sponsor exercises its right to extend the interest payment period for the
Debentures pursuant to Article IV of the First Supplemental Indenture (an
"Exclusion Period"), Distributions on the Securities shall, from the date of
original issue, accrue and be cumulative and shall be payable [quarterly], in
arrears, on each of _________, ________, _______, and __________, commencing
_______________, 20__, when, as and if available for payment, by the Property
Trustee, except as otherwise described below. Distributions are payable only to
the extent that payments are made in respect of the Debentures held by the

                                      35
<PAGE>

Property Trustee and to the extent that the Trust has funds available for the
payment of such Distributions in the Property Account.

     (b)  Distributions not paid on the scheduled payment date will accumulate
and compound (including interest payable on unpaid interest at the percentage
rate per annum set forth above, to the extent permitted by applicable law)
[quarterly] at the rate of ___% per annum ("Compounded Distributions").
"Distributions" shall mean ordinary cumulative distributions together with any
Compounded Distributions or any payment of Additional Tax Sums.

     (c)  If and to the extent that the Debenture Issuer makes a payment of
interest, premium and/or principal on the Debentures held by the Property
Trustee or any payment of Additional Tax Sums (the amount of any such payments
being a "Payment Amount"), the Property Trustee shall and is directed, to the
extent funds are available for that purpose, to make a Pro Rata distribution of
the Payment Amount to Holders, subject to Section 7.1(b).

     (d)  Distributions on the Securities shall be payable to the Holders
thereof as they appear on the register of the Trust as of the close of business
on the relevant record dates. While the Trust Preferred Securities are
represented by one or more Global Securities, the relevant record dates shall be
the close of business on the Business Day next preceding such Distribution
payment date, unless a different regular record date is established or provided
for the corresponding interest payment date on the Debentures. The relevant
record dates for the Common Securities shall be the same as for the Trust
Preferred Securities. If the Trust Preferred Securities shall not continue to
remain represented by one or more Global Securities, the relevant record dates
for the Trust Preferred Securities shall be selected by the Administrative
Trustees and shall be more than 14 days but no less than 60 days prior to the
relevant payment dates. At all times, the Distribution payment dates shall
correspond to the interest payment dates on the Debentures. Distributions
payable on any Securities that are not punctually paid on any Distribution
payment date, as a result of the Debenture Issuer having failed to make a
payment under the Debentures, shall cease to be payable to the Person in whose
name such Securities are registered on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined with respect to the related interest payment date pursuant to the
Indenture. If any date on which Distributions are payable on the Securities is
not a Business Day, then payment of the Distribution payable on such date will
be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding day which is a Business Day, in each case with the
same force and effect as if made on such payment date.

     (e)  In the event that there is any money or other property held by or for
the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata among the Holders of the Securities.

     Section 7.3  Redemption of Securities.
                  ------------------------

     (a)  Upon the repayment or redemption, in whole or in part, of the
Debentures held by the Trust, whether at the stated maturity of the Debentures
or upon earlier redemption or

                                      36
<PAGE>

acceleration as provided in the Indenture, the proceeds from such repayment or
redemption shall be simultaneously applied Pro Rata (subject to Section 7.1(b))
to redeem Securities having an aggregate Liquidation Amount equal to the
aggregate principal amount of the Debentures so repaid or redeemed at the
Redemption Price. Holders shall be given not less than 20 nor more than 60 days
notice of such redemption in accordance with Section 7.4.

     (b)  On the date fixed for any distribution of Debentures, upon dissolution
of the Trust, (i) the Securities will no longer be deemed to be outstanding and
(ii) certificates representing Securities will be deemed to represent the
Debentures having an aggregate principal amount equal to the stated Liquidation
Amount of, and bearing accrued and unpaid interest equal to accrued and unpaid
distributions on, such Securities until such certificates are presented to the
Sponsor or its agent for transfer or reissuance.

     (c)  Certificates called for redemption in whole must be surrendered to the
Paying Agent in order to receive payment of the Redemption Price.

     Section 7.4  Redemption Procedures.
                  ---------------------

     (a)  Notice of any redemption of, or notice of distribution of Debentures
in exchange for, the Securities (a "Redemption/Distribution Notice"), which
notice shall be irrevocable, will be given by the Trust by mail to each Holder
of Securities to be redeemed or exchanged not fewer than 20 nor more than 60
days before the date fixed for redemption or exchange thereof which, in the case
of a redemption, will be the date fixed for redemption of or the date of final
maturity of the Debentures. For purposes of the calculation of the date of
redemption or exchange and the dates on which notices are given pursuant to this
Section 7.4(a), a Redemption/Distribution Notice shall be deemed to be given on
the day such notice is first mailed by first-class mail, postage prepaid, to
Holders of Securities. Each Redemption/Distribution Notice shall be addressed to
the Holders of Securities at the address of each such Holder appearing in the
register of the Trust. No defect in the Redemption/Distribution Notice or in the
mailing of either thereof with respect to any Holder shall affect the validity
of the redemption or exchange proceedings with respect to any other Holder.

     (b)  If fewer than all the outstanding Securities are to be so redeemed,
the Common Securities and the Trust Preferred Securities will be redeemed Pro
Rata (subject to Section 7.1(b)) and the Trust Preferred Securities to be
redeemed will be redeemed as described in Section 7.4(c) below. The Trust may
not redeem the Securities in part unless all accumulated and unpaid
Distributions to the date of redemption have been paid in full on all Securities
then outstanding. For all purposes of this Trust Agreement, unless the context
otherwise requires, all provisions relating to the redemption of Trust Preferred
Securities shall relate, in the case of any Trust Preferred Security redeemed or
to be redeemed only in part, to the portion of the aggregate Liquidation Amount
of Trust Preferred Securities which has been or is to be redeemed.

     (c)  Subject to the Trust's fulfillment of the notice requirements set
forth in Section 7.4(a) above, if Securities are to be redeemed, then (i) with
respect to Trust Preferred Securities represented by one or more Global
Securities, by 2:00 p.m., New York City time, on the redemption date (provided
that the Debenture Issuer has paid the Property Trustee a sufficient amount of
immediately available funds in connection with the related redemption or
maturity of

                                      37
<PAGE>

the Debentures), the Property Trustee will deposit irrevocably with the
Depositary or its nominee (or successor Clearing Agency or its nominee) funds
sufficient to pay the applicable Redemption Price with respect to the Trust
Preferred Securities and will give the Depositary irrevocable instructions and
authority to pay the Redemption Price to the Holders of the Trust Preferred
Securities and (ii) with respect to Securities not represented by one or more
Global Securities (provided that the Debenture Issuer has paid the Property
Trustee a sufficient amount of immediately available funds in connection with
the related redemption or maturity of the Debentures), the Paying Agent will pay
the relevant Redemption Price to the Holders of such Securities by check mailed
to the address of the relevant Holder appearing on the register of the Trust on
the redemption date. If any date fixed for redemption of Securities is not a
Business Day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
is in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
in respect of any Securities is improperly withheld or refused and not paid
either by the Property Trustee or by the Sponsor as guarantor pursuant to the
Guarantee, Distributions on such Securities will continue to accrue at the then
applicable rate from the original redemption date to the actual 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. For these purposes,
the applicable Redemption Price shall not include Distributions which are being
paid to Holders who were Holders on a relevant record date. If a
Redemption/Distribution Notice shall have been given and funds deposited or paid
as required, then immediately prior to the close of business on the date of such
deposit or payment, Distributions will cease to accrue on the Securities called
for redemption and all rights of Holders of such Securities so called for
redemption will cease, except the right of the Holders to receive the Redemption
Price, but without interest on such Redemption Price, and from and after the
date fixed for redemption, such Securities will cease to be outstanding.

     Neither the Administrative Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Securities that have been
called for redemption, except in the case of any Securities being redeemed in
part, any portion thereof not to be redeemed.

     (d)  Subject to the foregoing and applicable law (including, without
limitation, United States federal securities laws), the Debenture Issuer or its
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 7.5  Voting Rights of Trust Preferred Securities.
                  -------------------------------------------

     (a)  Except as provided under Section 11.1 and this Article 7 and as
otherwise required by the Business Trust Act, the Trust Indenture Act and other
applicable law, the Holders of the Trust Preferred Securities shall have no
voting rights.

     (b)  Subject to the requirement of the Property Trustee obtaining a tax
opinion in certain circumstances set forth in Section 7.5(d) below, the Holders
of a Majority in Liquidation Amount of the Trust Preferred Securities voting
separately as a class have the right to direct the

                                      38
<PAGE>

time, method and place of conducting any proceeding for any remedy available to
the Property Trustee, or to direct the exercise of any trust or power conferred
upon the Property Trustee under the Trust Agreement, including the right to
direct the Property Trustee, as Holder of the Debentures, to (i) exercise the
remedies available to it under the Indenture as a Holder of the Debentures; (ii)
consent to any amendment or modification of the Indenture or the Debentures
where such consent shall be required (iii) waive any past default and its
consequences that is waivable under Section 6.6 of the Indenture or (iv) cancel
an acceleration of the principal of the Debentures; provided, however, that if
an Indenture Event of Default has occurred and is continuing, then the Holders
of 33% of the aggregate Liquidation Amount of the Trust Preferred Securities may
direct the Property Trustee to declare the principal of and interest on the
Debentures due and payable; provided, further, that where a consent or action
under the Indenture would require the consent or act of the Holders of more than
a majority of the aggregate principal amount of Debentures affected thereby,
only the Holders of the percentage of the aggregate stated Liquidation Amount of
the Trust Preferred Securities which is at least equal to the percentage
required under the Indenture may direct the Property Trustee to give such
consent to take such action provided, further, that (subject to the provisions
of Section 3.9) the Property Trustee shall have the right to decline to follow
any such direction if the Property Trustee shall determine that the action so
directed would be unjustly prejudicial to the Holders of Trust Preferred
Securities not taking part in such direction or if the Property Trustee, being
advised by counsel, determines that the action or proceeding so directed may not
lawfully be taken or if the Property Trustee, in good faith, by its board of
directors or trustees, executive committee, or a trust committee of directors or
trustees, and/or Responsible Officers, shall determine that the action or
proceeding so directed would involve the Property Trustee in personal liability.

     (c)  If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of Trust Preferred Securities has made a written
request, such Holder of Trust Preferred Securities may, to the extent permitted
by applicable law, institute a legal proceeding directly against the Debenture
Issuer to enforce the Property Trustee's rights under the Indenture without
first instituting any legal proceeding against the Property Trustee or any other
Person. In addition, if a Trust Enforcement Event has occurred and is continuing
and such event is attributable to the failure of the Debenture Issuer to make
any interest, principal or other required payments when due under the Indenture,
then a Holder of Trust Preferred Securities may directly institute a Direct
Action against the Debenture Issuer on or after the respective due date
specified in the Debentures.

     (d)  Subject to Section 2.7, the Property Trustee shall notify all Holders
of the Trust Preferred Securities of any notice of any Indenture Event of
Default received from the Debenture Issuer with respect to the Debentures. Such
notice shall state that such Indenture Event of Default also constitutes a Trust
Enforcement Event. Except with respect to directing the time, method, and place
of conducting a proceeding for a remedy, the Property Trustee shall be under no
obligation to take any of the actions described in clauses 7.5(b)(i) and (ii)
above unless the Property Trustee has obtained an opinion of independent tax
counsel to the effect that the Trust will not fail to be classified as a grantor
trust for United States federal income tax purposes as a result of such action,
and each Holder will be treated as owning an undivided beneficial ownership
interest in the Debentures.

                                      39
<PAGE>

     (e)  In the event the consent of the Property Trustee, as the Holder of the
Debentures, is required under the Indenture with respect to any amendment or
modification of the Indenture, the Property Trustee shall request the direction
of the Holders of the Securities with respect to such amendment or modification
and shall vote with respect to such amendment or modification as directed by not
less than a Majority in Liquidation Amount of the Securities voting together as
a single class; provided, however, that where a consent under the Indenture
would require the consent of the Holders of more than a majority of the
aggregate principal amount of the Debentures, the Property Trustee may only give
such consent at the direction of the Holders of at least the same proportion in
aggregate stated Liquidation Amount of the Securities. The Property Trustee
shall not take any such action in accordance with the directions of the Holders
of the Securities unless the Property Trustee has obtained an opinion of
independent tax counsel to the effect that the Trust will not be classified as
other than a grantor trust for United States federal income tax purposes as a
result of such action, and each Holder will be treated as owning an undivided
beneficial ownership interest in the Debentures.

     (f)  A waiver of an Indenture Event of Default with respect to the
Debentures will constitute a waiver of the corresponding Trust Enforcement
Event.

     (g)  Any required approval or direction of Holders of Trust Preferred
Securities may be given at a separate meeting of Holders of Trust Preferred
Securities convened for such purpose, at a meeting of all of the Holders of
Securities or pursuant to written consent. The Administrative Trustees will
cause a notice of any meeting at which Holders of Trust Preferred Securities are
entitled to vote to be mailed to each Holder of record of Trust Preferred
Securities. Each such notice will include a statement setting forth (i) the date
of such meeting, (ii) a description of any resolution proposed for adoption at
such meeting on which such Holders are entitled to vote and (iii) instructions
for the delivery of proxies.

     (h)  No vote or consent of the Holders of Trust Preferred Securities shall
be required for the Trust to redeem and cancel Trust Preferred Securities or
distribute Debentures in accordance with this Trust Agreement and the terms of
the Securities.

     (i)  Notwithstanding that Holders of Trust Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Securities that are owned at such time by the Debenture Issuer, any
Administrative Trustee or any entity directly or indirectly controlled by, or
under direct or indirect common control with, the Debenture Issuer or any
Administrative Trustee, shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if such Securities were not
outstanding; provided, however, that persons otherwise eligible to vote to whom
the Debenture Issuer or any of its subsidiaries have pledged Trust Preferred
Securities may vote or consent with respect to such pledged Trust Preferred
Securities under any of the circumstances described herein.

     (j)  Subject to Sections 6.6(a) and 7.5(k), Holders of the Trust Preferred
Securities shall have no rights to appoint or remove the Trustees, who may be
appointed, removed or replaced solely by the Common Securities Holder.

     (k)  Subject to the rights of the Holders of a Majority in Liquidation
Amount of the Common Securities to appoint or remove Administrative Trustees as
provided in Section

                                      40

6.6(a)(iii), if an Indenture Event of Default has occurred and is continuing,
the Trustees may be removed at such time only by a Majority in Liquidation
Amount of the Trust Preferred Securities.

decrease the number of Trustees.

otherwise eliminated and subject to the requirement of the Property Trustee
obtaining a tax opinion in certain circumstances set forth in this paragraph
(c), the Holders of a Majority in Liquidation Amount of the Common 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 this Trust Agreement,
including the right to direct the Property Trustee, as Holder of the Debentures,
to (i) exercise the remedies available to it under the Indenture as a Holder of
the Debentures, (ii) consent to any amendment or modification of the Indenture
or the Debentures where such consent shall be required or (iii) waive any past
default and its consequences that is waivable under Section 6.6 of the
Indenture; provided, however, that where a consent or action under the Indenture

Securities which is at least equal to the percentage required under the
Indenture may direct the Property Trustee to have such consent or take such

the Property Trustee shall determine that the action so directed would be
unjustly prejudicial to the Holders of Common Securities not taking part in such
direction or if the Property Trustee, being advised by counsel, determines that
the action or proceeding so directed may not lawfully be taken or if the
Property Trustee, in good faith, by its board of directors or trustees,
executive committee, or a trust committee of directors or trustees, and/or
Responsible officers, shall determine that the action or proceeding so directed
would involve the Property Trustee in personal liability. Except with respect to
directing the time, method, and place of conducting a proceeding for a remedy,
the Property Trustee shall be under no obligation to take any of the actions
described in clauses 7.6(c)(i) and (ii) above unless the Property Trustee has
obtained an opinion of independent tax counsel to the effect that, as a result
of such action, for United States federal income tax purposes the Trust will not
fail to be classified as a grantor trust and each Holder will be treated as
owning an undivided beneficial ownership interest in the Debentures.

     (d)  If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of Common Securities has made a written request, such
Holder of Common Securities

                                      41
<PAGE>

may, to the extent permitted by applicable law, directly institute a legal
proceeding directly against the Debenture Issuer to enforce the Property
Trustee's rights under the Debentures without first instituting any legal
proceeding against the Property Trustee or any other Person.

     (g)  No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
Debentures in accordance with the Trust Agreement and the terms of the
Securities.

     Section 7.7  Paying Agent. The Trust shall maintain in the Borough of
                  ------------
Manhattan, City of New York, State of New York, an office or agency where the
Trust Preferred Securities may be presented for payment ("Paying Agent"). The

without prior notice to the Holders. The Trust shall notify the Property Trustee
of the name and address of any Paying Agent not a party to this Trust Agreement.
If the Trust fails to appoint or maintain another entity as Paying Agent, the
Property Trustee shall act as such. The Trust or any of its Affiliates may act
as Paying Agent. The Property Trustee shall initially act as Paying Agent for
the Securities. In the event the Property Trustee shall no longer be the Paying
Agent, the Administrative Trustees shall appoint a successor (which shall be a

     (a)  Securities may only be transferred, in whole or in part, in accordance
with the terms and conditions set forth in this Trust Agreement and in the terms
of the Securities. To the fullest extent permitted by law, any transfer or
purported transfer of any Security not made in accordance with this Trust
Agreement shall be null and void.

     (b)  (i)     Subject to this Article 7 and to the requirements of the
          Securities Act and applicable state securities and blue sky laws, the
          Trust Preferred Securities shall be freely transferable.

                                      42
<PAGE>

          (ii)  The Holder of the Common Securities may not transfer the Common
     Securities except (A) in compliance with a consolidation, merger, sale,
     conveyance or lease of the Sponsor in compliance with Article XI of the
     Indenture or (B) to the Sponsor or an Affiliate thereof in compliance with
     applicable law, including the Securities Act and applicable state
     securities and blue sky laws. To the fullest extent permitted by law, any
     attempted transfer of the Common Securities other than as set forth in the
     immediately preceding sentence shall be null and void.

     (c)  The Trust shall cause to be kept at the Corporate Trust Office of the
Property Trustee a register (the register maintained in such office being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Trust shall provide for the
registration of Trust Preferred Securities and of transfers of Trust Preferred
Securities. The Property Trustee is hereby appointed "Security Registrar" for
the purpose of registering Trust Preferred Securities and transfers of Trust
Preferred Securities as herein provided.

     (d)  Upon surrender for registration of transfer of any Security at an
office or agency of the Trust designated for such purpose, the Trust shall
execute, and in the case of Trust Preferred Securities the Property Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denominations and of a
like aggregate principal amount.

     (e)  At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency. Whenever any Securities are so surrendered for exchange, the Trust shall
execute, and in the case of Trust Preferred Securities the Property Trustee
shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.

     (f)  Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Trust or the Property Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Trust and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

     (g)  No service charge shall be made for any registration of transfer or

with any registration of transfer or exchange of Securities.

     (h)  If the Securities are to be redeemed in part, the Trust shall not be

selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

     Section 7.10   Mutilated, Destroyed, Lost or Stolen Certificates.  If:
                    -------------------------------------------------

     (a)  any mutilated Certificates should be surrendered to the Administrative
Trustees or the Property Trustee, or if the Administrative Trustees and the
Property Trustee shall receive evidence to their satisfaction of the
destruction, loss or theft of any Certificate; and

     (b)  there shall be delivered to the Administrative Trustees and the
Property Trustee such security or indemnity as may be required by them to keep
each of the Trustees, the Sponsor and the Trust harmless, then, in the absence
of notice that such Certificate shall have been acquired by a bona fide
purchaser, any Administrative Trustee on behalf of the Trust shall execute and
deliver and, with respect to Trust Preferred Securities Certificates, the
Property Trustee shall authenticate, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination.

     In connection with the issuance of any new Certificate under this Section
7.10, the Administrative Trustees may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time. The provisions of this Section
are exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement of mutilated, destroyed, lost or stolen
Certificates.

     Section 7.11  Deemed Security Holders. The Trustees may treat the Person in
                   -----------------------
whose name any Certificate shall be registered on the register of the Trust as
the sole holder of such Certificate and of the Securities represented by such
Certificate for purposes of receiving Distributions (subject to Section 7.2(d))
and for all other purposes whatsoever and, accordingly, shall not be bound to
recognize any equitable or other claim to or interest in such Certificate or in
the Securities represented by such Certificate on the part of any Person,
whether or not the Trust shall have actual or other notice thereof.

     Section 7.12  Global Securities. The Trust Preferred Securities may be
                   -----------------
issued in the form of one or more Global Securities. If the Trust Preferred
Securities are to be issued in the form of one or more Global Securities, then
an Administrative Trustee on behalf of the Trust shall execute and the Property
Trustee shall authenticate and deliver one or more Global Securities that (i)
shall represent and shall be denominated in an amount equal to the aggregate
Liquidation Amount of all of the Trust Preferred Securities to be issued in the
form of Global Securities and not yet cancelled, (ii) shall be registered in the
name of the Depositary for such Global Security or the nominee of such
Depositary, and (iii) shall be delivered by the Property Trustee to such
Depositary or pursuant to such Depositary's instructions. Global Securities
shall bear a legend substantially to the following effect:

          "This Trust Preferred Security is a Global Security within the meaning
     of the Trust Agreement hereinafter referred to and is registered in the
     name of The Depository Trust Company, a New York corporation (the
     "Depositary"), or a nominee of the Depositary. This Trust Preferred
     Security is exchangeable for Trust Preferred Securities registered in the
     name of a person other than the Depositary or its nominee only in the

                                      44
<PAGE>

     limited circumstances described in the Trust Agreement and no transfer of
     this Trust Preferred Security (other than a transfer of this Trust
     Preferred Security as a whole by the Depositary to a nominee of the
     Depositary or by a nominee of the Depositary to the Depositary or another
     nominee of the Depositary) may be registered except in limited
     circumstances.

          Unless this Trust Preferred Security Certificate is presented by an
     authorized representative of the Depositary to Dominion CNG Capital Trust
     II or its agent for registration of transfer, exchange or payment, and any
     Trust Preferred Security Certificate issued is registered in the name of
     Cede & Co. or such other name as requested by an authorized representative
     of the Depositary (and any payment hereon is made to Cede & Co. or to such
     other entity as is requested by an authorized representative of the
     Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
     OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
     hereof, Cede & Co., has an interest herein."

     Trust Preferred Securities not represented by a Global Security issued in
exchange for all or a part of a Global Security pursuant to this Section 7.12
shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Property Trustee. Upon execution and
authentication, the Property Trustee shall deliver such Trust Preferred
Securities not represented by a Global Security to the Persons in whose names
such definitive Trust Preferred Securities are so registered.

     At such time as all interests in Global Securities have been redeemed,
repurchased or cancelled, such Global Securities shall be, upon receipt thereof,
cancelled by the Property Trustee in accordance with standing procedures of the
Depositary. At any time prior to such cancellation, if any interest in Global
Securities is exchanged for Trust Preferred Securities not represented by a
Global Security, redeemed, cancelled or transferred to a transferee who receives
Trust Preferred Securities not represented by a Global Security therefor or any
Trust Preferred Security not represented by a Global Security is exchanged or
transferred for part of Global Securities, the principal amount of such Global
Securities shall, in accordance with the standing procedures of the Depositary,
be reduced or increased, as the case may be, and an endorsement shall be made on
such Global Securities by the Property Trustee to reflect such reduction or
increase.

     The Trust and the Property Trustee may for all purposes, including the
making of payments due on the Trust Preferred Securities, deal with the
Depositary as the authorized representative of the Holders for the purposes of
exercising the rights of Holders hereunder. The rights of the owner of any
beneficial interest in a Global Security shall be limited to those established
by law and agreements between such owners and depository participants provided,
that no such agreement shall give any rights to any Person against the Trust or
the Property Trustee without the written consent of the parties so affected.
Multiple requests and directions from and votes of the Depositary as holder of
Trust Preferred Securities in global form with respect to any particular matter
shall not be deemed inconsistent to the extent they do not

                                      45
<PAGE>

represent an amount of Trust Preferred Securities in excess of those held in the
name of the Depositary or its nominee.

     If at any time the Depositary for any Trust Preferred Securities
represented by one or more Global Securities notifies the Trust that it is
unwilling or unable to continue as Depositary for such Trust Preferred
Securities or if at any time the Depositary for such Trust Preferred Securities
shall no longer be eligible to act as such under the Exchange Act, the Trust
shall appoint a successor Depositary with respect to such Trust Preferred
Securities. If a successor Depositary for such Trust Preferred Securities is not
appointed by the Trust within 90 days after the Trust receives such notice or
becomes aware of such ineligibility, the Trust's election that such Trust
Preferred Securities be represented by one or more Global Securities shall no
longer be effective and the Trust shall execute, and the Property Trustee will
authenticate and deliver, Trust Preferred Securities in definitive registered
form, in any authorized denominations, in an aggregate Liquidation Amount equal
to the principal amount of the Global Security representing such Trust Preferred
Securities in exchange for such Global Security.

     The Trust may at any time and in its sole discretion determine that the
Trust Preferred Securities issued in the form of one or more Global Securities
shall no longer be represented by a Global Security. In such event the Trust
shall execute, and the Property Trustee, shall authenticate and deliver, Trust
Preferred Securities in definitive registered form, in any authorized
denominations, in an aggregate Liquidation Amount equal to the principal amount
of the Global Security representing such Trust Preferred Securities, in exchange
for such Global Security.

     Notwithstanding any other provisions of this Trust Agreement (other than
the provisions set forth in Section 7.9), Global Securities may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

     Subject to the third preceding paragraph, interests of beneficial owners in
a Global Security may be transferred or exchanged for Trust Preferred Securities
not represented by a Global Security and Trust Preferred Securities not
represented by a Global Security may be transferred or exchange for Global
Securities in accordance with rules of the Depositary and the provisions of
Section 7.9.

redemption, registration of transfer or exchange shall, if surrendered to any
Person other than the Property Trustee, be delivered to the Property Trustee and
shall be promptly cancelled by it. No Certificates shall be executed or
authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as permitted by this Trust Agreement. All
cancelled Certificates held by the Property Trustee shall be disposed of by it
in accordance with its customary procedures.

     Section 8.1  Dissolution and Termination of Trust.
                  ------------------------------------

     (a)  The Trust shall dissolve upon the earliest of:

                  (i)    a Bankruptcy Event of the Holder of the Common
          Securities or the Sponsor;

                  (ii)   the filing of a certificate of dissolution or its
          equivalent with respect to the Sponsor; the dissolution of the Trust
          after obtaining the consent of the Holders of at least a Majority in
          Liquidation Amount of the Securities to dissolve the Trust; or the
          revocation of the Sponsor's charter and the expiration of 90 days
          after the date of revocation without a reinstatement thereof;

                  (iii)  the entry of a decree of judicial dissolution of the
          Sponsor or the Trust;

                  (iv)   the time when all of the Securities shall have been
          called for redemption and the amounts then due shall have been paid to
          the Holders in accordance with the terms of the Securities;

                  (v)    at the Sponsor's election by notice and direction to
          the Property Trustee to distribute the Debentures to the Holders of
          the Securities in exchange for all of the Securities; provided that
          the Sponsor will be required to obtain an opinion of an independent
          counsel that the distribution of the Debentures will not be taxable to
          the Holders of the Trust Preferred Securities for United States
          federal income tax purposes; or

                  (vi)   the time when all of the Administrative Trustees and
          the Sponsor shall have consented to dissolution of the Trust provided
          such action is taken before the issuance of any Securities.

     (b)  As soon as is practicable after the occurrence of an event referred to
in Section 8.1(a) and upon completion of the winding up and liquidation of the
Trust, the Trustees shall terminate the Trust by filing a certificate of
cancellation with the Secretary of State of the State of Delaware.

     (c)  The provisions of Section 4.2 and Article 9 shall survive the
termination of the Trust.

     Section 8.2  Liquidation Distribution Upon Dissolution of the Trust.
                  ------------------------------------------------------

     (a)  In the event of any voluntary or involuntary liquidation, dissolution,
or winding-up of the Trust (each a "Liquidation"), the Holders of the Securities
on the date of the Liquidation will be entitled to receive, out of the assets of
the Trust available for distribution to Holders of Securities after satisfaction
of the Trusts' liabilities to creditors, if any, distributions

                                      47
<PAGE>

in cash or other immediately available funds in an amount equal to the aggregate
of the stated Liquidation Amount of $__ per Security plus accumulated and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless, in connection with such Liquidation, the Debentures
shall be distributed on a Pro Rata basis to the Holders of the Securities in
exchange for such Securities.

     (b)    If, upon any such Liquidation, the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then the amounts payable directly
by the Trust on the Securities shall be paid on a Pro Rata basis. The Holders of
the Common Securities will be entitled to receive distributions upon any such
Liquidation Pro Rata with the Holders of the Trust Preferred Securities except
that if an Indenture Event of Default has occurred and is continuing, the Trust
Preferred Securities shall have a preference over the Common Securities with
regard to such distributions.

 LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES, DELAWARE TRUSTEES OR OTHERS

     Section 9.1  Liability.
                  ---------

     (a)    Except as expressly set forth in this Trust Agreement, the Guarantee
and the terms of the Securities, the Sponsor:

                  (i)    shall not be personally liable for the return of any
            portion of the capital contributions (or any return thereon) of the
            Holders of the Securities which shall be made solely from assets of
            the Trust; and

                  (ii)   shall not be required to pay to the Trust or to any
            Holder of Securities any deficit upon dissolution of the Trust or
            otherwise.

     (b)    Pursuant to Section 3803(a) of the Business Trust Act, the Holder of
the Common Securities shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware; provided, however,
the Holders of the Common Securities shall be liable for all of the debts and
obligations of the Trust (other than with respect to the Securities) to the
extent not satisfied out of the Trust's assets.

     (c)    Pursuant to Section 3803(a) of the Business Trust Act, the Holders
of the Trust Preferred Securities shall be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the General Corporation Law of the State of Delaware.

     Section 9.2  Exculpation.
                  -----------

     (a)    No Indemnified Person shall be liable, responsible or accountable in
damages or otherwise to the Trust or any Covered Person for any loss, damage or
claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith on behalf of the Trust and in a manner such
Indemnified Person reasonably believed to be within the scope of

                                      48
<PAGE>

the authority conferred on such Indemnified Person by this Trust Agreement or by
law, except that an Indemnified Person shall be liable for any such loss, damage
or claim incurred by reason of such Indemnified Person's gross negligence or
willful misconduct with respect to such acts or omissions.

     (b)  An Indemnified Person 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 Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has, if selected by such Indemnified Person, been selected by
such Indemnified Person with reasonable care 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 Securities
might properly be paid.

     Section 9.3  Fiduciary Duty.
                  --------------

     (a)  To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Trust Agreement shall not be liable to the Trust or to another Covered Person
for its good faith reliance on the provisions of this Trust Agreement. The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person.

     (b)  Unless otherwise expressly provided herein:

                  (i)   whenever a conflict of interest exists or arises between
          any Covered Person and any Indemnified Person; or

                  (ii)  whenever this Trust Agreement or any other agreement
          contemplated herein or therein provides that an Indemnified Person
          shall act in a manner that is, or provides terms that are, fair and
          reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Trust Agreement or any other
agreement contemplated herein or of any duty or obligation of the Indemnified
Person at law or in equity or otherwise.

     (c)  Whenever in this Trust Agreement an Indemnified Person is permitted or
required to make a decision:

                                      49
<PAGE>

                 (i)  in its "discretion" or under a grant of similar authority,
          the Indemnified Person shall be entitled to consider such interests
          and factors as it desires, including its own interests, and shall have
          no duty or obligation to give any consideration to any interest of or
          factors affecting the Trust or any other Person; or

                 (ii) in its "good faith" or under another express standard, the
          Indemnified Person shall act under such express standard and shall not
          be subject to any other or different standard imposed by this Trust
          Agreement or by applicable law.

     Section 9.4 Indemnification.
                 ---------------

     (a) (i)     The Debenture Issuer shall indemnify, to the full extent
     permitted by law, any Debenture Issuer Indemnified Person who was or is a
     party or is threatened to be made a party to any threatened, pending or
     completed action, suit or proceeding, whether civil, criminal,
     administrative or investigative (other than an action by or in the right of
     the Trust) by reason of the fact that he is or was a Debenture Issuer
     Indemnified Person against expenses (including attorney fees), judgments,
     fines and amounts paid in settlement actually and reasonably incurred by
     him in connection with such action, suit or proceeding if he acted in good
     faith and in a manner he reasonably believed to be in or not opposed to the
     best interests of the Trust, and, with respect to any criminal action or
     proceeding, had no reasonable cause to believe his conduct was unlawful.
     The termination of any action, suit or proceeding by judgment, order,
     settlement, conviction or upon a plea of nolo contendere or its equivalent,
     shall not, of itself, create a presumption that the Debenture Issuer
     Indemnified Person did not act in good faith and in a manner which he
     reasonably believed to be in or not opposed to the best interests of the
     Trust, and, with respect to any criminal action or proceeding, had
     reasonable cause to believe that his conduct was unlawful.

         (ii)    The Debenture Issuer shall indemnify, to the full extent
     permitted by law, any Debenture Issuer Indemnified Person who was or is a
     party or is threatened to be made a party to any threatened, pending or
     completed action or suit by or in the right of the Trust to procure a
     judgment in its favor by reason of the fact that he is or was a Debenture
     Issuer Indemnified Person against expenses (including attorneys' fees)
     actually and reasonably incurred by him in connection with the defense or
     settlement of such action or suit if he acted in good faith and in a manner
     he reasonably believed to be in or not opposed to the best interests of the
     Trust and except that no such indemnification shall be made in respect of
     any claim, issue or matter as to which such Debenture Issuer Indemnified
     Person shall have been adjudged to be liable to the Trust unless and only
     to the extent that the Court of Chancery of Delaware or the court in which
     such action or suit was brought shall determine upon application that,
     despite the adjudication of liability but in view of all the circumstances
     of the case, such person is fairly and reasonably entitled to indemnity for
     such expenses which such Court of Chancery or such other court shall deem
     proper.

                                      50
<PAGE>

                  (iii) Any indemnification under paragraphs (i) and (ii) of
         this Section 9.4(a) (unless ordered by a court) shall be made by the
         Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Debenture Issuer Indemnified
         Person is proper in the circumstances because he has met the applicable
         standard of conduct set forth in paragraphs (i) and (ii). Such
         determination shall be made (1) by the Administrative Trustees by a
         majority vote of a quorum consisting of such Administrative Trustees
         who were not parties to such action, suit or proceeding, (2) if such a
         quorum is not obtainable, or, even if obtainable, if a quorum of
         disinterested Administrative Trustees so directs, by independent legal
         counsel in a written opinion, or (3) by the Holders of the Common
         Securities of the Trust.

                  (iv)  Expenses (including attorneys' fees) incurred by a
         Debenture Issuer Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section 9.4(a) shall be paid by the
         Debenture Issuer in advance of the final disposition of such action,
         suit or proceeding upon receipt of an undertaking by or on behalf of
         such Debenture Issuer Indemnified Person to repay such amount if it
         shall ultimately be determined that he is not entitled to be
         indemnified by the Debenture Issuer as authorized in this Section
         9.4(a). Notwithstanding the foregoing, no advance shall be made by the
         Debenture Issuer if a determination is reasonably and promptly made (i)
         by the Administrative Trustees by a majority vote of a quorum of
         disinterested Administrative Trustees, (ii) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Administrative Trustees so directs, by independent legal counsel in a
         written opinion or (iii) the Common Security Holder of the Trust, that,
         based upon the facts known to the Administrative Trustees, counsel or
         the Common Security Holder at the time such determination is made, such
         Debenture Issuer Indemnified Person acted in bad faith or in a manner
         that such person did not believe to be in or not opposed to the best
         interests of the Trust, or, with respect to any criminal proceeding,
         that such Debenture Issuer Indemnified Person believed or had
         reasonable cause to believe his conduct was unlawful. In no event shall
         any advance be made in instances where the Administrative Trustees,
         independent legal counsel or Common Security Holder reasonably
         determine that such person deliberately breached his duty to the Trust
         or its Common or Trust Preferred Security Holders.

                  (v)   The indemnification and advancement of expenses provided
         by, or granted pursuant to, the other paragraphs of this Section 9.4(a)
         shall not be deemed exclusive of any other rights to which those
         seeking indemnification and advancement of expenses may be entitled
         under any agreement, vote of stockholders or disinterested directors of
         the Debenture Issuer or Trust Preferred Security Holders of the Trust
         or otherwise, both as to action in his official capacity and as to
         action in another capacity while holding such office. All rights to
         indemnification under this Section 9.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Debenture
         Issuer Indemnified Person who serves in such capacity at any time while
         this Section 9.4(a) is in effect. Any repeal or modification of this
         Section 9.4(a) shall not affect any rights or obligations then
         existing.

                  (vi)  The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Debenture
         Issuer Indemnified Person against any

                                      51
<PAGE>

         liability asserted against him and incurred by him in any such
         capacity, or arising out of his status as such, whether or not the
         Debenture Issuer would have the power to indemnify him against such
         liability under the provisions of this Section 9.4(a).

         Trust" shall include, in addition to the resulting or surviving entity,
         any constituent entity (including any constituent of a constituent)
         absorbed in a consolidation or merger, so that any person who is or was

         director, trustee, officer, employee or agent of another entity, shall
         stand in the same position under the provisions of this Section 9.4(a)
         with respect to the resulting or surviving entity as he would have with

         provided when authorized or ratified, continue as to a person who has
         ceased to be a Debenture Issuer Indemnified Person and shall inure to
         the benefit of the heirs, executors and administrators of such a
         person. The obligation to indemnify as set forth in this Section 9.4(a)

     Section 10.2   Certain Accounting Matters.
                    --------------------------

     (a)  At all times during the existence of the Trust, the Administrative
Trustees shall keep, or cause to be kept, full books of account, records and
supporting documents, which shall reflect in reasonable detail, each transaction
of the Trust. The books of account shall be maintained on the accrual method of
accounting, in accordance with generally accepted accounting principles,
consistently applied. The Trust shall use the accrual method of accounting for
United States federal income tax purposes. The books of account and the records
of the Trust shall be examined by and reported upon as of the end of each Fiscal
Year of the Trust by a firm of independent certified public accountants selected
by the Administrative Trustees.

     (b)  The Administrative Trustees shall cause to be prepared and delivered
to each of the Holders of Securities, within 90 days after the end of each
Fiscal Year of the Trust, annual financial statements of the Trust, including a
balance sheet of the Trust as of the end of such Fiscal Year, and the related
statements of income or loss.

     (c)  The Administrative Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, an annual United States federal
income tax information statement, required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations. Notwithstanding any right under the Code
to deliver any such statement at a later date, the Administrative Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

     (d)  The Administrative Trustees shall cause to be duly prepared and filed
with the appropriate taxing authority, an annual United States federal income
tax return, on a Form 1041 or such other form required by United States federal
income tax law, and any other annual income tax returns required to be filed by
the Administrative Trustees on behalf of the Trust with any state or local
taxing authority.

                    -------
in the name and for the sole benefit of the Trust; provided, however, that all
payments of funds in respect of the Debentures held by the Property Trustee
shall be made directly to the Property Account and no other funds of the Trust
shall be deposited in the Property Account. The sole signatories for

                                      53

such accounts shall be designated by the Administrative Trustees; provided,
however, that the Property Trustee shall designate the signatories for the
Property Account.

     Section 10.4   Withholding. The Trust and the Administrative Trustees shall
                    -----------
comply with all withholding requirements under United States federal, state and
local law. The Trust shall request, and the Holders shall provide to the Trust,
such forms or certificates as are necessary to establish an exemption from
withholding with respect to each Holder, and any representations and forms as
shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations. The Administrative
Trustees shall file required forms with applicable jurisdictions and, unless an
exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions. To the
extent that the Trust is required to withhold and pay over any amounts to any
authority with respect to distributions or allocations to any Holder, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to the Holder. In the event of any claimed over withholding, Holders shall be
limited to an action against the applicable jurisdiction. If the amount required
to be withheld was not withheld from actual Distributions made, the Trust may
reduce subsequent Distributions by the amount of such withholding.

          of any distribution of the Securities or otherwise adversely affect
          the amount of any distribution required to be made in respect of the
          Securities as of a specified date or (b) restrict the right of a
          Holder of Securities to institute suit for the enforcement of any such
          payment on or after such date, will entitle the Holders of such
          Securities, voting together as a single class, to vote on such

          effective except with the approval of each of the Holders of the
          Securities affected thereby; and

          powers, preferences or rights of the Securities, whether by way of
          amendment to this Trust Agreement or otherwise or (b) result in the
          dissolution, winding-up or termination of the Trust other than

                    --------------------------------------------------------
Consent.
-------

     (a)  Meetings of the Holders of any class of Securities may be called at
any time by the Administrative Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Trust Agreement, the
terms of the Securities or the rules of any stock exchange on which the Trust
Preferred Securities are listed or admitted for trading. The Administrative
Trustees shall call a meeting of the Holders of such class if directed to do so
by the Holders of at least 10% in Liquidation Amount of such class of
Securities. Such direction shall be given by delivering to the Administrative
Trustees one or more calls in a writing stating that the signing Holders of
Securities wish to call a meeting and indicating the general or specific purpose
for which the meeting is to be called. Any Holders of Securities calling a
meeting shall specify in writing the Certificates held by the Holders of
Securities exercising the right to call a meeting and only those Securities
specified shall be counted for purposes of determining whether the required
percentage set forth in the second sentence of this paragraph has been met.

     (b)  Except to the extent otherwise provided in the terms of the
Securities, the following provisions shall apply to meetings of Holders of
Securities:

                                      56
<PAGE>

     (i)   notice of any such meeting shall be given to all the Holders of
Securities having a right to vote thereat at least 7 days and not more than 60
days before the date of such meeting. Whenever a vote, consent or approval of
the Holders of Securities is permitted or required under this Trust Agreement or
the rules of any stock exchange on which the Trust Preferred Securities are
listed or admitted for trading, such vote, consent or approval may be given at a
meeting of the Holders of Securities. Any action that may be taken at a meeting
of the Holders of Securities may be taken without a meeting and without prior
notice if a consent in writing setting forth the action so taken is signed by
the Holders of Securities owning not less than the minimum amount of Securities
in Liquidation Amount that would be necessary to authorize or take such action
at a meeting at which all Holders of Securities having a right to vote thereon
were present and voting. Prompt notice of the taking of action without a meeting
shall be given to the Holders of Securities entitled to vote who have not
consented in writing. The Administrative Trustees may specify that any written
ballot submitted to the Security Holders for the purpose of taking any action
without a meeting shall be returned to the Trust within the time specified by
the Administrative Trustees;

     (ii)  each Holder of a Security may authorize any Person to act for it by
proxy on all matters in which a Holder of Securities is entitled to participate,
including waiving notice of any meeting, or voting or participating at a
meeting. No proxy shall be valid after the expiration of 11 months from the date
thereof unless otherwise provided in the proxy. Every proxy shall be revocable
at the pleasure of the Holder of Securities executing such proxy. Except as
otherwise provided herein, all matters relating to the giving, voting or
validity of proxies shall be governed by the General Corporation Law of the
State of Delaware relating to proxies, and judicial interpretations thereunder,
as if the Trust were a Delaware corporation and the Holders of the Securities
were stockholders of a Delaware corporation;

     (iii) each meeting of the Holders of the Securities shall be conducted by
the Administrative Trustees or by such other Person that the Administrative
Trustees may designate; and

     (iv)  unless the Business Trust Act, this Trust Agreement, the terms of the
Securities, the Trust Indenture Act or the listing rules of any stock exchange
on which the Trust Preferred Securities are then listed for trading, otherwise
provide, the Administrative Trustees, in their sole discretion, shall establish
all other provisions relating to meetings of Holders of Securities, including
notice of the time, place or purpose of any meeting at which any matter is to be
voted on by any Holders of Securities, waiver of any such notice, action by
consent without a meeting, the establishment of a record date, quorum
requirements, voting in person or by proxy or any other matter with respect to
the exercise of any such right to vote.
