                                TRUST AGREEMENT
                                      OF

hereby agree as follows:

     1.   The trust created hereby shall be known as "CNG CAPITAL TRUST I" (the

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. (S) 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 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

                                       1

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

other person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which distributions to holders of Trust securities might properly be
paid.

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

          (a) to indemnify and hold harmless each Fiduciary Indemnified Persons,
or any of its officers, directors, shareholders, employees, representatives or
agents, from and against any

loss, damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by the Fiduciary Indemnified Persons by reason of the
creation, operation or termination of the Trust in a manner the Fiduciary
Indemnified Persons reasonably believed to be within the scope of authority
conferred on the Fiduciary Indemnified Persons by this Trust Agreement, except
that no Fiduciary Indemnified Persons shall be entitled to be indemnified in
respect of any loss, damage or claim incurred by the Fiduciary Indemnified
Persons by reason of negligence or willful misconduct with respect to such acts
or omissions; and

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

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

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

          otherwise eliminated, and until such Trust Enforcement Events with
          respect to the Trust Preferred Securities have been so cured, waived

          Securities and only the Holders of the Trust Preferred Securities will
          have the right to direct the Property Trustee in accordance with 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

          thereon.

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

default except:

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

none of the Trustees (including the Property Trustee) shall cause the Trust to:

               (i)   invest any proceeds received by the Trust from holding the
          Debentures, but shall distribute all such proceeds to Holders of
          Securities pursuant to the terms of this Trust Agreement and of the
          Securities;

               (ii)  acquire any assets other than as expressly provided herein;

<PAGE>

               (vi)   possess any power or otherwise act in such a way as to

     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:

               (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

                                       17
<PAGE>

          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 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:

                                       18
<PAGE>

               (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.

     Section 3.9  Certain Duties and Responsibilities of the Property 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:

                     (A) the duties and obligations of the Property 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

                                       19
<PAGE>

                      (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

          manner as the Property Trustee deals with similar property for its own

          afforded to the Property Trustee under this Trust Agreement and the

          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,

          its obligation to exercise the rights and powers vested in it by this
          Trust Agreement in the manner provided by Section 3.9(a);

          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

          such expenses (including the reasonable fees and expenses of its

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

Administrative Trustees, and except as otherwise required by the Business Trust

     Section 3.14  Duration of Trust. The Trust shall exist until terminated

     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

               (B)  substitutes for the Trust Preferred Securities other
     securities having substantially the same terms as the Trust Preferred
     Securities (the

                                       24
<PAGE>

     "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.

capacity as Debenture Issuer, agrees

     (a)  to pay to the Property Trustee and the Delaware Trustee from time to

applicable requirements.

               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

an instrument of resignation or removal, the resigning or removed Property
Trustee or Delaware Trustee, as applicable, may petition any court of competent
jurisdiction for appointment of a Successor Property Trustee or Successor
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.

     Section 6.7  Vacancies among Trustees. If a Trustee ceases to hold
                  ------------------------
office 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
Section 6.6.

     Section 6.8  Effect of Vacancies. The death, resignation, retirement,
                  -------------------
removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to
perform the duties of a Trustee shall not operate to annul, dissolve or
terminate the Trust. Whenever a vacancy in the number of Administrative Trustees
shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 6.6, the Administrative
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.

     Section 6.9  Meetings. If there is more than one Administrative Trustee,
                  --------
meetings of the Administrative Trustees shall be held from time to time upon the
call of any Administrative

<PAGE>

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
3.6, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing.

     (b) The Administrative Trustees shall have power to delegate from time 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
part of any of the parties hereto.

     (a) The Administrative Trustees shall on behalf of the Trust issue one
class of Trust Preferred Securities representing undivided beneficial ownership
interests in the assets of the Trust and one class of common securities
representing undivided beneficial ownership interests in the assets of the
Trust.

             (i) Trust Preferred Securities. On the initial Closing Date, an
          Administrative Trustee, on behalf of the Trust, shall execute and
          deliver to the underwriters named in the underwriting agreement
          relating to such Trust Preferred Securities, a Trust Preferred
          Securities Certificate, registered in the name of the initial
          Depositary, in an initial aggregate amount of ____________ Trust
          Preferred Securities. Pursuant to the procedures established in an
          Officer's Certificate, the Trust may subsequently issue from time to
          time Tranches of Trust Preferred Securities. The Trust Preferred
          Securities shall have an aggregate Liquidation Amount with respect to
          the assets of the Trust of ____________ ($____). The Trust Preferred
          Securities and any subsequent Tranches thereof are hereby designated
          for identification purposes only as "CNG Capital Trust I ___% Trust
          Preferred Securities" (the "Trust Preferred Securities"). The Trust
          Preferred Security Certificates evidencing the Trust Preferred
          Securities shall be substantially in the form of Exhibit A to this
          Trust Agreement, with such changes and additions thereto or deletions
          therefrom as may be required by ordinary usage, custom or practice or
          to conform to the rules of any stock exchange on which the Trust
          Preferred Securities are listed or quoted.

             (ii) Common Securities. On the initial Closing Date, an
          Administrative Trustee, on behalf of the Trust, shall execute and
          deliver to the Sponsor Common Securities Certificates, registered in
          the name of the Sponsor, in an initial aggregate amount of
          ______________ Common Securities. Pursuant to the procedures
          established in an Officer's Certificate, the Trust may subsequently
          issue from time to time Tranches of Common Securities. The Common
          Securities shall have an initial aggregate Liquidation Amount with
          respect to the assets of the Trust of One Thousand dollars ($1,000).
          The Common Securities and any subsequent Tranches thereof are hereby
          designated for identification purposes only as "CNG Capital Trust I
          ____% Common Securities" (the "Common Securities" and, together with
          the Trust Preferred Securities, the "Securities"). The Common Security
          Certificates evidencing the Common Securities shall be substantially
          in the form of Exhibit B to this Trust Agreement, with such changes
          and additions thereto or deletions therefrom as may be required by
          ordinary usage, custom or practice.

             (iii) On the initial Closing Date, an Administrative Trustee, on
          behalf of the Trust, shall subscribe to and purchase from the Sponsor
          Debentures, registered in the name of the Property Trustee, on behalf
          of the Trust and the Holders and having an initial aggregate principal
          amount equal to $_____________________. To the extent subsequent
          Tranches of Securities are issued, an Administrative Trustee, on
          behalf of the Trust, shall subscribe to and purchase from the Sponsor
          Debentures, registered in the name of the Property Trustee, on behalf
          of the Trust and to Holders having an aggregate principal

                                       33
<PAGE>

          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
all Distribution periods terminating on or prior thereto, or, in the case of
amounts payable on redemption, the full amount of the Redemption Price for all
of the outstanding Trust Preferred Securities then called for redemption, shall
have been made or provided for, and all funds available to the Property Trustee
shall first be applied to the payment in full in cash of all Distributions on,
or the Redemption Price of, the Trust Preferred Securities then due and payable.
The Trust shall issue no securities or other interests in the assets of the
Trust other than the Trust Preferred Securities and the Common Securities.

      (c) The Certificates shall be signed on behalf of the Trust by an
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 Certificates representing Trust Preferred
Securities for original issue and (ii) concurrently with

                                       34
<PAGE>

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 semiannual 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 Second Supplemental Indenture (an "Exclusion Period"),
Distributions on the Securities shall, from the date of original issue, accrue
and be cumulative and shall be payable semiannually, in arrears, on the [last]
day of each June and December, commencing June __, 2001, 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 Property Trustee and to the extent that
the Trust has funds available for the payment of such Distributions in the
Property Account.

                                       35
<PAGE>

  (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)
semiannually 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 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

                                       36
<PAGE>

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 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

                                       37
<PAGE>

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 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

                                       38
<PAGE>

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.

  (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,

                                       39
<PAGE>

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 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.

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

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

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 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 may, to the extent permitted by applicable law, directly
institute a legal proceeding directly

                                       41
<PAGE>

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.

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

  (f) Any required approval or direction of Holders of Common Securities may be
given at a separate meeting of Holders of Common 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 Common Securities are entitled to vote to be mailed to each Holder of
record of Common Securities. Each such notice will include a statement setting

  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

satisfactory to the Trust and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

     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.

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 CNG Capital Trust I 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

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 $1,000 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.

     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).

          (vii)  For purposes of this Section 9.4(a), references to "the 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 a director,
     trustee, officer or employee of such constituent entity, or is or was
     serving at the request of such constituent entity as a 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 respect to such
     constituent entity if its separate existence had continued.

          (viii) The indemnification and advancement of expenses provided by, or
     granted pursuant to, this Section 9.4(a) shall, unless otherwise 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) shall survive the resignation
     or removal of the Delaware Trustee or the Property Trustee or the
     termination of this Trust Agreement.

     (b)  The Debenture Issuer agrees to indemnify the (i) Property Trustee,
(ii) the Delaware Trustee, (iii) any Affiliate of the Property Trustee or the
Delaware Trustee, and (iv) any officers, directors, shareholders, members,
partners, employees, representatives, custodians, nominees or agents of the
Property Trustee or the Delaware Trustee (each of the Persons in (i) through
(iv) being referred to as a "Fiduciary Indemnified Person") for, and to hold
each Fiduciary Indemnified Person harmless against, any loss, liability or
expense incurred without gross negligence or willful misconduct on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or investigating
any claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder. The obligation to indemnify as set forth in this
Section 9.4(b) shall survive the resignation and removal of the Delaware Trustee
or the Property Trustee and the dissolution of the Trust and the termination of
this Trust Agreement. In addition, the Debenture Issuer has agreed in the
Indenture to pay the fees and expenses of the Delaware Trustee and the Property
Trustee.

     Section 9.5  Outside Businesses.  Subject to the provisions of Section 6.3,
                  ------------------
any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee
may engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the
activities of the Trust, and the Trust and the Holders of Securities shall have
no rights by virtue of this Trust Agreement in and to such independent ventures
or the income or profits derived therefrom, and the pursuit of any such venture,
even if competitive with the activities of the Trust, shall not be deemed
wrongful or improper. No Covered Person, the Sponsor, the Delaware Trustee or
the Property Trustee shall be obligated to present any particular investment or
other opportunity to the Trust even if such opportunity is of a character that,
if presented to the Trust, could be taken by the Trust, and any Covered Person,
the Sponsor,

                                      52
<PAGE>

the Delaware Trustee and the Property Trustee shall have the right to take for
its own account (individually or as a partner or fiduciary) or to recommend to
others any such particular investment or other opportunity. Any Covered Person,
the Delaware Trustee and the Property Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the Sponsor,
or may act as depositary for, trustee or agent for, or act on any committee or
body of holders of, securities or other obligations of the Sponsor or its
Affiliates.

     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.

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.

     Section 11.1  Amendments.
                   ----------

     (a)  Except as otherwise provided in this Trust Agreement or by any
applicable terms of the Securities, this Trust Agreement may only be amended by
a written instrument approved and executed by the Sponsor and (i) the
Administrative Trustees (or, if there are more than two Administrative Trustees,
a majority of the Administrative Trustees), (ii) the Property Trustee; and (iii)
the Delaware Trustee if the amendment affects the rights, powers, duties,
obligations or immunities of the Delaware Trustee.

               the terms of this Trust Agreement (including the terms of the
               Securities) and that all conditions precedent to the execution

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.

Securities, the following provisions shall apply to meetings of Holders of
Securities:

          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

          consent without a meeting, the establishment of a record date, quorum
          requirements, voting in person or by proxy or any other matter with
