                                                                              12

that, if the Event of Default arises out of an Indenture Event of Default:

                  (i) which is not waivable under the Indenture, the
         Event of Default under this Declaration shall also be
         not waivable; or

                  (ii) which requires the consent or vote of (1) holders of
         Debentures representing a specified percentage greater than a majority
         in principal amount of the Debentures affected thereby, or (2) each
         holder of Debentures, the Event of Default under this Declaration may
         only be waived by, in the case of clause (1) above, the vote of Holders
         of Preferred Securities representing such specified percentage of the
         aggregate liquidation amount of the Preferred Securities or, in the
         case of clause (2) above, each Holder of Preferred Securities affected
         thereby.

Upon such waiver, any such default shall cease to exist, and any Event of
Default with respect to the Preferred Securities arising therefrom shall be
deemed to have been cured for every purpose of this Declaration, but no such
waiver shall extend to any subsequent or other default or Event of Default with
respect to the Preferred Securities or impair any right consequent thereto.

                  (b) Subject to Section 2.06(c), Holders of Common Securities
may, by vote of at least a Majority in liquidation amount of the Common
Securities, (A) in accordance with the terms of the Common Securities, direct

Securities, waive any past Event of Default with respect to the Common
Securities and its consequences; provided that if the Event of Default arises
out of an Indenture Event of Default:

                  (i) which is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the
<PAGE>   21
                                                                              13

         Declaration as provided below, the Event of Default under this
         Declaration shall also not be waivable; or

                  (ii) which requires the consent or vote of (1) holders of
         Debentures representing a specified percentage greater than a majority
         in principal amount of the Debentures or (2) each holder of Debentures
         affected thereby, except where the holders of the Common Securities are
         deemed to have waived such Event of Default under this Declaration as
         provided below, the Event of Default under this Declaration may only be
         waived by, in the case of clause (1) above, the vote of Holders of
         Common Securities representing such specified percentage of the
         aggregate liquidation amount of the Common Securities or, in the case
         of clause (2) above, each holder of Common Securities affected thereby;
         and

provided further that each Holder of Common Securities will be deemed to have
waived any Event of Default with respect to the Common Securities and its
consequences until all Events of Default with respect to the Preferred
Securities have been cured or waived by the Holders of Preferred Securities as
provided in this Declaration or otherwise eliminated and until all Events of
Default with respect to the Preferred Securities have been so cured, waived or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of the Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Property Trustee in
accordance with the terms of this Declaration or the Securities. In the event
that an Event of Default with respect to the Preferred Securities is waived by
the Holders of Preferred Securities as provided in this Declaration, the Holders
of Common Securities agree that such waiver shall also constitute the waiver of
such Event of Default with respect to the Common Securities for all purposes
under this Declaration without any further act, vote or consent of the Holders
of the Common Securities. Subject to the foregoing provisions of this Section
2.06(b), upon such waiver, any such default shall cease to exist and any Event
of Default with respect to the Common Securities arising therefrom shall be
deemed to have been cured for every purpose of this Declaration, but no such
waiver shall extend to any

subsequent or other default or Event of Default with respect to the Common
Securities or impair any right consequent thereon.

                  (c) The right of any Holder of Securities to receive payment
of Distributions on the Securities in accordance with this Declaration and the
terms of the Securities set forth in Exhibits B and C on or after the respective
payment dates therefor, or to institute suit for the enforcement of any such
payment on or after such payment dates, shall not be impaired without the
consent of such Holder.

                  (d) As provided in the terms of the Securities set forth in
Exhibits B and C hereto, a waiver of an Indenture Event of Default by the
Property Trustee at the written direction of the Holders of the Preferred
Securities constitutes a waiver of the corresponding Event of Default under this
Declaration in respect of the Securities.

                  SECTION 2.07. Disclosure of Information. The disclosure of
information as to the names and addresses of the Holders of the Securities in
accordance with Section 312 of the Trust Indenture Act, regardless of the source
from which such information was derived, shall not be deemed to be a violation
of any existing law or any law hereafter enacted which does not specifically
refer to Section 312 of the Trust Indenture Act, nor shall the Property Trustee
be held accountable by reason of mailing any material pursuant to a request made
under Section 312(b) of the Trust Indenture Act.

                  (h)(i) direct the time, method and place of exercising any
         trust or power conferred upon the Debenture Trustee with respect to the
         Debentures, (ii) waive any past default that is waivable under Section
         6.06 of the Indenture, (iii) exercise any right to rescind or annul any
         declaration that the principal of all of the Debentures shall be due
         and payable or (iv) consent to any amendment, modification or
         termination of the Indenture or the Debentures, where such consent
         shall be required, unless in the case of this clause (h) the Property
         Trustee shall have received an unqualified opinion of nationally
         recognized independent tax counsel recognized as expert in such matters
         to the effect that such action will not cause the Trust to be
         classified for United States Federal income tax purposes as an
         association taxable as a corporation or partnership and that the Trust
         will continue to be classified as a grantor trust for United States
         federal income tax purposes.

                  SECTION 3.10. Powers and Duties of the Property Trustee. (a)
The Debentures shall be held of record in the name of the Property Trustee in
trust for the benefit of 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 Article V. Such vesting and cessation of title shall be effective whether
or not conveyancing documents have been executed and delivered.

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

                  (c)  The Property Trustee shall:

                  (i) establish and maintain a segregated non-interest bearing
         bank 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 on 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, without any further acts of the Property
         Trustee or the Regular Trustees, promptly make payments to the Holders
         of the Preferred Securities and Common Securities from the Property
         Account in accordance with Section 6.01. Funds in the Property Account
         shall be held uninvested, and without liability for interest thereon,
         until disbursed in accordance with this Declaration. The Property
         Account shall be an account which is maintained with a banking
         institution whose long term unsecured indebtedness is rated by a
         "nationally recognized statistical rating organization", as such term
         is defined for purposes of Rule 436(g)(2) under the Securities Act, at
         least equal to (but in no event less than "A" or the equivalent) the
         rating assigned to the Preferred Securities by a nationally recognized
         statistical rating organization;

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

                  (iii) upon notice of distribution issued by the Regular
         Trustees in accordance with the terms of the Preferred Securities and
         the Common Securities, engage in such ministerial activities as shall
         be necessary or appropriate to effect promptly, pursuant to the terms
         of the Securities, the distribution of Debentures to Holders of
         Securities upon the occurrence of a Special Event; and

                  (iv) have the legal power to exercise all of the rights,
         powers and privileges of a holder of the Debentures under the Indenture
         and, if an Event of

<PAGE>   32
                                                                              24

         Default occurs and is continuing, the Property Trustee, subject to
         Section 2.06(b), shall, for the benefit of the Holders of the
         Securities, enforce its rights as holder of the Debentures under the
         Indenture, subject to the rights of the Holders of the Preferred
         Securities pursuant to the terms of this Declaration, the Business
         Trust Act and the Trust Indenture Act.

                  (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 the Securities set forth in Exhibits B and C hereto.

                  (e) The Property Trustee shall take any Legal Action which
arises out of or in connection with an Event of Default or the Property
Trustee's duties and obligations under this Declaration, the Business Trust Act
or the Trust Indenture Act.

                  (f) All moneys deposited in the Property Account, and all
Debentures held by the Property Trustee for the benefit of the Holders of the
Securities, will not be subject to any right, charge, security interest, lien or
claim of any kind in favor of, or for the benefit of, the Property Trustee or
its agents or their creditors.

                  (g) The Property Trustee shall, within 90 days after the
occurrence of a default with respect to the Securities, transmit by mail, first
class postage prepaid, to the Holders of the Securities, as their names and
addresses appear upon the register, notice of all defaults with respect to the
Securities known to the Property Trustee, unless such defaults shall have been
cured before the giving of such notice (the term "defaults" for the purposes of
this Section 3.10(g) being hereby defined to be an Indenture Event of Default,
not including any periods of grace provided for in the Indenture and
irrespective of the giving of any notice provided therein); provided that,
except in the case of default in the payment of the principal of (or premium, if
any) or interest on any of the Debentures, the Property Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Property
<PAGE>   33
                                                                              25


Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of the Securities. The Property Trustee shall not be
deemed to have knowledge of any default, except (i) a default in the payment of
principal of (or premium, if any) or interest on the Debentures or (ii) any
default as to which the Property Trustee shall have received written notice or a
Responsible Officer charged with the administration of this Declaration shall
have obtained written notice.

                  (h)  The Property Trustee shall not resign as a
Trustee unless either:

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

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

                  (i) The Property Trustee shall act as paying agent in respect
of the Common Securities and the Preferred Securities and, subject to Section
3.08(r), may authorize one or more Persons (each, a "Paying Agent") to pay
Distributions, redemption payments or liquidation payments on behalf of the
Trust with respect to the Preferred Securities. Any such Paying Agent shall
comply with Section 317(b) of the Trust Indenture Act. Any Paying Agent may be
removed by the Property Trustee, after consultation with the Regular Trustees,
at any time and a successor Paying Agent or additional Paying Agents may be
appointed at any time by the Property Trustee, subject to Section 3.08(r).

                  (j) The Property Trustee shall give prompt written notice to
the Holders of the Securities of any notice received by it from PWG of its
election to defer payments of interest on the Debentures by extending the
interest payment period with respect thereto.

                  (k) Subject to this Section 3.10, the Property Trustee shall
have none of the powers or the authority of the Regular Trustees set forth in
Section 3.08.
<PAGE>   34
                                                                              26

                  (1) The Property Trustee shall exercise the powers, duties and
rights set forth in this Section 3.10 and Section 3.12 in a manner which is
consistent with the purposes and functions of the Trust set out in Section 3.05,
and the Property Trustee shall not take any action which is inconsistent with
the purposes and functions of the Trust set forth in Section 3.05.

                  SECTION 3.11. Delaware Trustee. Notwithstanding any other
provision of this Declaration other than Section 5.01(a)(3), the Delaware
Trustee shall not be entitled to exercise any powers, nor shall the Delaware
Trustee have any of the duties and responsibilities of the Regular Trustees or
the Property Trustee described in this Declaration. Except as set forth in
Section 5.01(a)(3), the Delaware Trustee shall be a Trustee for the sole and
limited purpose of fulfilling the requirements of Section 3807 of the Business
Trust Act. In the event the Delaware Trustee shall at any time be required to
take any action or perform any duty hereunder, the Delaware Trustee shall be
entitled to the benefits of Section 3.12(b)(ii), (iii) and (iv) and Section
3.12(c). No implied covenants or obligations shall be read into this Declaration
against the Delaware Trustee.

                  SECTION 3.12. Certain Rights and Duties of the Property
Trustee. (a) The Property Trustee, before the occurrence of an Event of Default
and after the curing or waiving of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Declaration, and no implied covenants shall be read into this Declaration
against the Property Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.06), the Property Trustee shall
exercise such of the rights and powers vested in it by this Declaration, 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.

                                                                              27

                  (b) No provision of this Declaration 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 an Event of Default and after
         the curing or waiving of all such Events of Default that may have
         occurred:

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

                           (B) in the absence of bad faith on the part of the
                  Property Trustee, the Property Trustee may conclusively rely,
                  as to the truth of the statements and the correctness of the
                  opinions expressed therein, upon any certificates or opinions
                  furnished to the Property Trustee and conforming to the
                  requirements of this Declaration; 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 Declaration;

                  (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 as provided herein
         relating to the time,
<PAGE>   36
                                                                              28

         method and place of conducting any proceeding for any remedy available
         to the Property Trustee hereunder or under the Indenture, or exercising
         any trust or power conferred upon the Property Trustee under this
         Declaration; and

                  (iv) no provision of this Declaration 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 ground for believing that the repayment of such funds or
         liability is not reasonably assured to it under the terms of this
         Declaration or adequate indemnity against such risk or liability is not
         reasonably assured to it.

                  (c)  Subject to the provisions of Section 3.12(a)
and (b):

                  (i) whenever in the administration of this Declaration, the
         Property Trustee shall deem it desirable that a matter be proved or
         established prior to 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
         and, if the Trust is excluded from the definition of Investment Company
         solely by means of Rule 3a-7, subject to the requirements of Rule 3a-7,
         request and rely upon a certificate, which shall comply with the
         provisions of Section 314(e) of the Trust Indenture Act, signed by any
         two of the Regular Trustees or by an authorized officer of the Sponsor,
         as the case may be;

                  (ii) the Property Trustee (A) may consult with counsel (which
         may be counsel to the Sponsor or any of its Affiliates and may include
         any of its employees) selected by it in good faith and with due care
         and the written advice or opinion of such counsel with respect to legal
         matters shall be full and complete authorization and protection in
         respect of any action taken, suffered or omitted by it hereunder in
         good faith and in reliance thereon and in accordance with such advice
         and opinion and (B) shall have the right at
<PAGE>   37
                                                                              29

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

                  (iii) the Property Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through agents or attorneys and the Property Trustee shall not be
         responsible for any misconduct or negligence on the part of any agent
         or attorney appointed by it in good faith and with due care;

                  (iv) the Property Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Declaration
         at the request or direction of any Holders, unless such Holders shall
         have offered to the Property Trustee reasonable security and indemnity
         against the costs, expenses (including attorneys' fees and expenses)
         and liabilities that might be incurred by it in complying with such
         request or direction; provided that nothing contained in this clause
         (iv) shall relieve the Property Trustee of the obligation, upon the
         occurrence of an Event of Default (which has not been cured or waived)
         to exercise such of the rights and powers vested in it by this
         Declaration, and to use the same degree of care and skill in such
         exercise, as a prudent person would exercise or use under the
         circumstances in the conduct of his or her own affairs;

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

                  (vi) the Property Trustee may rely and shall be fully
         protected in acting or refraining from acting
<PAGE>   38
                                                                              30


         upon any resolution, certificate, statement, instrument, opinion,
         report, notice, request, consent, order, approval, bond, security or
         other paper or document believed by it to be genuine and to have been
         signed, sent or presented by the proper party or parties; and

                  (vii) the Property Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, approval, bond, security or other paper or document,
         but the Property Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit.

                  SECTION 3.13. Registration Statement and Related Matters. In
accordance with the Original Declaration, PWG and the Trustees have authorized
and directed, and hereby confirm the authorization of, PWG, as the sponsor of

that the Property Trustee and the Delaware Trustee, 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

the same, with all exhibits thereto, and other documents in connection
therewith, with the Commission, granting unto said attorneys-in-fact and agents
full power and authority to do and perform each and every act and thing
requisite and necessary to be done in connection therewith, as fully to all
intents and purposes as PWG or such Trustee might or could do in person, hereby
ratifying and confirming all that said attorneys-in-fact and agents or any of
them, or their or his or her substitute or substitutes, shall do or cause to be
done by virtue hereof.

such date are issued, such purchase to be in such amount so that the Common
Securities continue to represent 3% of the total capital of the Trust.

                  SECTION 4.02. Expenses. (a) In connection with the purchase of
the Debentures by the Trust, the Sponsor, in its capacity as Sponsor and not as

costs and expenses incurred in connection with the disposition of Trust assets).

                  (b) In connection with the purchase of the Debentures by the
Trust, the Sponsor, in its capacity as Sponsor and not as a Holder, will pay any
and all taxes (other than United States withholding taxes attributable to the
Trust or its assets) and all liabilities, costs and expenses with respect to
such taxes of the Trust.

                  (c) The Sponsor's obligations under this Section 4.02 shall be
for the benefit of, and shall be enforceable by, any Person to whom any such
debts, obligations, costs, expenses and taxes are owed (a "Creditor") whether or
not such Creditor has received notice hereof. Any such Creditor may enforce the
Sponsor's obligations under this Section 4.02 directly against the Sponsor and
the Sponsor irrevocably waives any right or remedy to require that any such
Creditor take any action against the Trust or any other Person before proceeding
against the Sponsor. The Sponsor agrees to execute such additional agreements as
may be necessary or desirable in

                  SECTION 5.01. Number of Trustees; Qualifications. (a) Except
as provided in (1) below, the number of Trustees initially shall be five (5). At
any time (i) before the issuance of the Securities, the Sponsor may, by written
instrument, increase or decrease the number of, and appoint, remove and replace
the, Trustees, and (ii) after the issuance of the Securities the number of
Trustees may be increased or decreased solely by, and Trustees may be appointed,

provided that in any case:

                  (1) the number of Trustees shall be at least five (5) unless
         the Trustee that acts as the Property Trustee also acts as the Delaware
         Trustee, in which case the number of Trustees shall be at least three
         (3);

                  (2) at least a majority of the Trustees shall at all times be
         officers or employees of PWG;

                  (3) if required by the Business Trust Act, one Trustee (the
         "Delaware Trustee") shall be either 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 and
         otherwise is permitted to act as a Trustee hereunder under the laws of
         the State of Delaware, except that if the Property Trustee has its
         principal place of business in the State of Delaware and otherwise is
         permitted to act as a Trustee hereunder under the laws of the State of
         Delaware, then the Property Trustee shall also be the Delaware Trustee
         and Section 3.09 shall have no application; and

                                                                              35

                                             New York, New York 10019

                  (c) There shall at all times be one Trustee which shall act as
Property Trustee. In order to act as Property Trustee hereunder, such Trustee

         and subject to supervision or examination by Federal, State,
         Territorial or District of Columbia authority. If such corporation
         publishes reports of condition at least annually, pursuant to law or to
         the requirements of the supervising or examining authority referred to
         above, then for the purposes of this Section 5.01(c)(ii), the combined
         capital and surplus of such corporation shall be deemed to be its
         combined capital and surplus as set forth in its most recent report of
         condition so published; and
<PAGE>   44
                                                                              36

                  (iii) if the Trust is excluded from the definition of an
         Investment Company solely by reason of Rule 3a-7 and to the extent Rule
         3a-7 requires a trustee having certain qualifications to hold title to
         the "eligible assets" (as defined in Rule 3a-7) of the Trust, the
         Property Trustee shall possess those qualifications.

                  If at any time the Property Trustee shall cease to satisfy the
requirements of clauses (i)-(iii) above, the Property Trustee shall immediately
resign in the manner and with the effect set out in Section 5.02(d). If the
Property Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Property Trustee and
the Holders of the Common Securities (as if such Holders were the obligor
referred to in Section 310(b) of the Trust Indenture Act) shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act. The
Preferred Guarantee shall be deemed to be specifically described in this
Declaration for the purposes of clause (i) of the first proviso contained in
Section 310(b) of the Trust Indenture Act.

                  The initial Trustee which shall serve as the Property Trustee

                  (d) The initial Trustee which shall serve as the Delaware
Trustee is Chase Manhattan Bank Delaware, a Delaware banking corporation, whose

                  (e) Any action taken by Holders of Common Securities pursuant
to this Article V shall be taken at a meeting of Holders of Common Securities
convened for such purpose or by written consent as provided in Section 12.02.

                  (f) No amendment may be made to this Section 5.01 which would
change any rights with respect to the number, existence or appointment and
removal of Trustees, except with the consent of each Holder of Common
Securities.

                  SECTION 5.02. Appointment, Removal and Resignation of
Trustees. (a) Subject to Section 5.02(b), Trustees may be appointed or removed
without cause at any time:

                  (i) until the issuance of the Securities, by written

         Holders of a Majority in liquidation amount of the Common Securities
         voting as a class.

                  (b)(i) The Trustee that acts as Property Trustee shall not be
         removed in accordance with Section 5.02(a) until a Successor Property
         Trustee possessing the qualifications to act as Property Trustee under
         Section 5.01(c) has been appointed and has accepted such appointment by
         written instrument executed by such Successor Property Trustee and
         delivered to the Regular Trustees, the Sponsor and the Property Trustee
         being removed; and

                  (ii) the Trustee that acts as Delaware Trustee shall not be
         removed in accordance with Section 5.02(a) until a successor Trustee
         possessing the qualifications to act as Delaware Trustee under Section
         5.01(a)(3) (a "Successor Delaware Trustee") has been appointed and has
         accepted such appointment by written instrument executed by such
         Successor Delaware Trustee and delivered to the Regular Trustees, the
         Sponsor and the Delaware Trustee being removed.

                  (c) A Trustee appointed to office shall hold office until his
         successor shall have been appointed or until his death, removal or
         resignation.

                  (d) Any Trustee may resign from office (without need for prior
         or subsequent accounting) by an instrument (a "Resignation Request") in
         writing signed by the Trustee and delivered to the Sponsor and the
<PAGE>   46
                                                                              38


         Trust, which resignation shall take effect upon such delivery or upon
         such later date as is specified therein; provided, however, that:

                  (i) no such resignation of the Trustee that acts as the
         Property Trustee shall be effective until:

                           (A) a Successor Property Trustee possessing the
                  qualifications to act as Property Trustee under Section
                  5.01(c) has been appointed and has accepted such appointment
                  by instrument executed by such Successor Property Trustee and
                  delivered to the Trust, the Sponsor and the resigning Property
                  Trustee; or

                           (B) if the Trust is excluded from the definition of
                  an Investment Company solely by reason of Rule 3a-7, until the
                  assets of the Trust have been completely liquidated and the
                  proceeds thereof distributed to the Holders of the Securities;
                  and

                  (ii) no such resignation of the Trustee that acts as the
         Delaware Trustee shall be effective until a Successor Delaware Trustee
         has been appointed and has accepted such appointment by instrument
         executed by such Successor Delaware Trustee and delivered to the Trust,
         the Sponsor and the resigning Delaware Trustee.

                  (e) If no Successor Property Trustee or Successor Delaware
         Trustee shall have been appointed and accepted appointment as provided
         in this Section 5.02 within 60 days after delivery to the Sponsor and
         the Trust of a Resignation Request, the resigning Property Trustee or
         Delaware Trustee may petition any court of competent jurisdiction for
         appointment of a Successor Property Trustee or Successor Delaware
         Trustee. Such court may thereupon, after such notice, if any, as it may
         deem proper and prescribe, appoint a Successor Property Trustee or
         Successor Delaware Trustee, as the case may be.

                  (f) The Sponsor shall provide notice to the Property Trustee
         of any resignation or removal of a Regular Trustee.

                  SECTION 5.03. Vacancies Among Trustees. If a Trustee ceases to
hold office for any reason and the number of Trustees is not reduced pursuant to
Section 5.01 or if the number of Trustees is increased pursuant to Section 5.01,
a vacancy shall occur. A resolution certifying the existence of such vacancy by
a majority of the Regular Trustees shall be conclusive evidence of the existence
of such vacancy. The vacancy shall be filled with a Trustee appointed in
accordance with the requirements of this Article V.

                  SECTION 5.04. Effect of Vacancies. The death, resignation,
retirement, removal, bankruptcy, dissolution, liquidation, incompetence or
incapacity to perform the duties of a Trustee, or any one of them, shall not
operate to annul the Trust. Whenever a vacancy in the number of Regular Trustees
shall occur until such vacancy is filled as provided in this Article V, the
Regular Trustees in office, regardless of their number, shall have all the
powers granted to the Regular Trustees and shall discharge all the duties
imposed upon the Regular Trustees by this Declaration.

                  SECTION 5.05. Meetings. Meetings of the Regular Trustees shall
be held from time to time upon the call of any Trustee. Regular meetings of the
Regular Trustees may be held at a time and place fixed by resolution of the

with a hard copy by overnight courier) not less than 48 hours before such
meeting. Notice of any telephonic meeting of the Regular Trustees or any
committee thereof 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 such 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 a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a

Regular 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 Declaration, any action of
the Regular Trustees may be taken at a meeting by vote of a majority of the
Regular 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 Regular Trustees.

                  SECTION 5.06. Delegation of Power. (a) Any Regular Trustee
may, by power of attorney consistent with applicable law, delegate to any other
natural person over the age of 21 his or her power for the purpose of executing
any registration statement or amendment thereto or other document or schedule
filed with the Commission or making any other governmental filing (including,
without limitation the filings referred to in Section 3.13).

                  (b) The Regular Trustees shall have the power to delegate from
time to time to such of their number or to officers of the Trust or to officers
of PWG or PaineWebber Incorporated the doing of such things and the execution of
such instruments either in the name of the Trust or the names of the Regular
Trustees or otherwise as the Regular 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.

                                   ARTICLE VI

                                  Distributions

                  SECTION 6.01. Distributions. Holders shall receive periodic

interest (including Compounded Interest (as defined in the

                                                                              41


Indenture)), premium or principal on the Debentures held by the Property Trustee
(the amount of any such payment being a "Payment Amount"), the Property Trustee
shall and is directed to promptly make a Distribution of the Payment Amount to
Holders in accordance with the terms of the Securities as set forth in Exhibits
B and C hereto.

                                   ARTICLE VII

                             Issuance of Securities

                  SECTION 7.01. General Provisions Regarding Securities. (a) The
Regular Trustees shall issue on behalf of the Trust Securities in fully
registered form representing undivided beneficial interests in the assets of the
Trust in accordance with Section 7.01(b) and for the consideration specified in
Section 3.03.

                  (b) The Regular Trustees shall issue on behalf of the Trust
one class of preferred securities representing preferred undivided beneficial
interests in the assets of the Trust having such terms as are set forth in
Exhibit B (the "Preferred Securities") which terms are incorporated by reference
in, and made a part of, this Declaration as if specifically set forth herein,
and one class of common securities representing common undivided beneficial
interests in the assets of the Trust having such terms as are set forth in
Exhibit C (the "Common Securities") which terms are incorporated by reference
in, and made a part of, this Declaration as if specifically set forth herein.
The Trust shall have no securities or other interests in the assets of the Trust
other than the Preferred Securities and the Common Securities.

                  (c) The Certificates shall be signed on behalf of the Trust by
the Regular Trustees (or if there are more than two Regular Trustees by any two
of the Regular Trustees). Such signatures may be the manual or facsimile
signatures of the present or any future Regular Trustee. Typographical and other
minor errors or defects in any such reproduction of any such signature shall not
affect the validity of any Certificate. In case any Regular Trustee of the Trust
who shall have signed any of the Certificates shall cease to be

                                                                              42


such Regular Trustee before the Certificate so signed shall be delivered by the
Trust, such Certificate nevertheless may be delivered as though the person who
signed such Certificate had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons as, at the
actual date of the execution of such Certificate, shall be the Regular Trustees
of the Trust, although at the date of the execution and delivery of the
Declaration any such person was not such a Regular Trustee. Certificates shall
be printed, lithographed or engraved or may be produced in any other manner as
is reasonably acceptable to the Regular Trustees, as evidenced by their
execution thereof, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements as the Regular
Trustees may deem appropriate, or as may be required to comply with any law or
with any rule or regulation made pursuant thereto or with any rule or regulation
of any stock exchange on which the Securities may be listed, or to conform to
usage. Pending the preparation of definitive Certificates, the Regular Trustees
on behalf of the Trust may execute temporary Certificates (printed, lithographed
or typewritten), in substantially the form of the definitive Certificates in
lieu of which they are issued, but with such omissions, insertions and
variations as may be appropriate for temporary Certificates, all as may be
determined by the Regular Trustees. Each temporary Certificate shall be executed
by the Regular Trustees on behalf of the Trust upon the same conditions and in
substantially the same manner, and with like effect, as definitive Certificates.
Without unnecessary delay, the Regular Trustees on behalf of the Trust will
execute and furnish definitive Certificates and thereupon any or all temporary
Certificates may be surrendered to the transfer agent and registrar in exchange
therefor (without charge to the Holders). Each Certificate whether in temporary
or definitive form shall be countersigned by the manual or facsimile signature
of an authorized signatory of the Person acting as registrar and transfer agent
for the Securities, which shall initially be the Property Trustee.

                  (d) The consideration received by the Trust for the issuance
of the Securities shall constitute a

Trust.

                  (e) Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

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

                  (g) Upon issuance of the Securities as provided in this
Declaration, the Regular Trustees on behalf of the Trust shall return to PWG the
$10 constituting initial trust assets as set forth in the Original Declaration.

         redemption and the amounts necessary for redemption thereof shall have
         been paid to the Holders of Securities in accordance with the terms of
         the Securities; or

                  (ii) all of the Debentures shall have been distributed to the
         Holders of Securities in exchange for all of the Securities in
         accordance with the terms of the Securities; or

                  (iii) upon the expiration of the term of the Trust
         as set forth in Section 3.17,

and thereafter the Trustees shall, after satisfaction of all obligations of the
Trust, file a certificate of cancelation with the Secretary of State of the
State of Delaware and the Trust shall terminate. The Trustees shall so file such
a

certificate as soon as practicable after the occurrence of an event referred to
in this Section 8.01.

                  The provisions of Sections 3.12 and 4.02 and Article X shall
survive the termination of the Trust.

                                   ARTICLE IX

                              Transfer of Interests

                  SECTION 9.01. Transfer of Securities. (a) Securities may only
be transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration. Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.

                  (b) Subject to this Article IX, Preferred Securities shall be
freely transferable.

                  (c) Subject to this Article IX, PWG and any Related Party may
only transfer Common Securities to PWG or a Related Party; provided that any
such transfer shall be subject to the condition that the transferor shall have
obtained (1) either a ruling from the Internal Revenue Service or an unqualified
written opinion addressed to the Trust and delivered to the Trustees of
nationally recognized independent tax counsel experienced in such matters to the
effect that such transfer will not (i) cause the Trust to be treated as issuing
a class of interests in the Trust differing from the class of interests
represented by the Common Securities originally issued to PWG, (ii) result in
the Trust acquiring or disposing of, or being deemed to have acquired or
disposed of, an asset, or (iii) result in or cause the Trust to be treated as
anything other than a grantor trust for United States Federal income tax
purposes and (2) an unqualified written opinion addressed to the Trust and
delivered to the Trustees of a nationally recognized independent counsel
experienced in such matters that such transfer will not cause the Trust to be an
Investment Company or controlled by an Investment Company.

                  SECTION 9.02. Transfer of Certificates. The Regular Trustees
shall cause to be kept at an office or agency to be maintained by the Trust a
register in which, subject to such reasonable regulations as it may prescribe,
the Trust shall provide for the registration of Certificates and of transfers of
Certificates, which will be effected without charge but only upon payment (with
such indemnity as the Trust or the Registrar (as defined below) may require) in
respect of any tax or other government charges which may be imposed in relation
to it. The Property Trustee will be the initial registrar and transfer agent
(the "Registrar") for the purpose of registering Certificates and transfers of
Certificates as provided herein.

                  Upon surrender for registration of transfer of any Certificate
at the office or agency of the Registrar, the Regular Trustees shall execute and
the Registrar shall countersign in accordance with section 7.01(c) one or more
new Certificates of any authorized denominations and of a like aggregate
liquidation amount to be issued in the name of the designated transferee or
transferees. Every Certificate surrendered for registration of transfer shall be
accompanied by a written instrument of transfer in form satisfactory to the
Trust duly executed by the Holder or such Holder's attorney duly authorized in
writing. Each Certificate surrendered for registration of transfer shall be
canceled by the Regular Trustees. A transferee of a Certificate shall be
entitled to the rights and subject to the obligations of a Holder hereunder upon
the receipt by such transferee of a Certificate. By acceptance of a Certificate,
each transferee shall be deemed to have agreed to be bound by this Declaration.

                  SECTION 9.03. Deemed Security Holders. The Trustees may treat
the Person in whose name any Certificate shall be registered on the books and
records of the Trust as the sole holder of such Certificate and of the
Securities represented by such Certificate for purposes of receiving
Distributions 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 Trustees shall have actual or other notice
thereof.

                  SECTION 9.04. Book Entry Interests. Unless otherwise specified
in the terms of the Preferred Securities, the Preferred Securities Certificates,
on original issuance (including Preferred Securities, if any, issued on the
Option Closing Date pursuant to the exercise of the overallotment option set
forth in the Underwriting Agreement), will be issued in the form of one or more,
fully registered, global Preferred Security Certificates (each a "Global
Certificate"), to be delivered to DTC, the initial Clearing Agency, by, or on
behalf of, the Trust. Such Global Certificates shall initially be registered on
the books and records of the Trust in the name of Cede & Co., the nominee of
DTC, and no Preferred Security Beneficial Owner will receive a definitive
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certificates, except as provided in Section
9.07. Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") have been issued
to the Preferred Security Beneficial Owners pursuant to Section 9.07:

                  (i) the provisions of this Section 9.04 shall be in full force
         and effect;

                  (ii) the Trust and the Trustees shall be entitled to deal with
         the Clearing Agency for all purposes of this Declaration (including the
         payment of Distributions on the Global Certificates and receiving
         approvals, votes or consents hereunder) as the Holder of the Preferred
         Securities and the sole holder of the Global Certificates and shall
         have no obligation to the Preferred Security Beneficial Owners;

                  (iii) to the extent that the provisions of this Section 9.04
         conflict with any other provisions of this Declaration, the provisions
         of this Section 9.04 shall control; and

                  (iv) the rights of the Preferred Security Beneficial Owners
         shall be exercised only through the Clearing Agency and shall be
         limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing

                                                                              47

         Agency and/or the Clearing Agency Participants. DTC will make book
         entry transfers among the Clearing Agency Participants and receive and
         transmit payments of Distributions on the Global Certificates to such
         Clearing Agency Participants.

                  SECTION 9.05. Notices to Holders of Certificates. Whenever a
notice or other communication to the Holders is required to be given under this
Declaration, unless and until Definitive Preferred Security Certificates shall
have been issued pursuant to Section 9.07, the relevant Trustees shall give all
such notices and communications, specified herein to be given to Preferred
Securities Holders, to the Clearing Agency and, with respect to any Preferred
Security Certificate registered in the name of a Clearing Agency or the nominee
of a Clearing Agency, the Trustees shall, except as set forth herein, have no
notice obligations to the Preferred Security Beneficial Owners.

                  SECTION 9.06. Appointment of Successor Clearing Agency. If any
Clearing Agency elects to discontinue its services as securities depository with
respect to the Preferred Securities, the Regular Trustees may, in their sole
discretion, appoint a successor Clearing Agency with respect to the Preferred
Securities.

                  SECTION 9.07. Definitive Preferred Securities Certificates. If
(i) a Clearing Agency elects to discontinue its services as securities
depository with respect to the Preferred Securities and a successor Clearing
Agency is not appointed within 90 days after such discontinuance pursuant to
Section 9.06 or (ii) the Regular Trustees elect after consultation with the
Sponsor to terminate the book entry system through the Clearing Agency with
respect to the Preferred Securities, then (x) Definitive Preferred Security
Certificates shall be prepared by the Regular Trustees on behalf of the Trust
with respect to such Preferred Securities and (y) upon surrender of the Global
Certificates by the Clearing Agency, accompanied by registration instructions,
the Regular Trustees shall cause definitive Preferred Security Certificates to
be delivered to Preferred Security Beneficial Owners in accordance with the
instructions of the Clearing Agency. Neither the Trustees nor the Trust shall be
liable for any delay in
<PAGE>   56
                                                                              48

delivery of such instructions and each of them may conclusively rely on, and
shall be protected in relying on, such instructions.

                  SECTION 9.08. Mutilated, Destroyed, Lost or Stolen
Certificates. If (a) any mutilated Certificates should be surrendered to the
Registrar, or if the Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there shall be delivered
to the Trustees such security or indemnity as may be required by them to keep
each of them harmless, then in the absence of notice that such Certificate shall
have been acquired by a bona fide purchaser, any two Regular Trustees on behalf
of the Trust shall execute and deliver, 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 9.08, the Regular 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.

                                    ARTICLE X

                    Limitation of Liability; Indemnification

                  SECTION 10.01 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 the authority conferred on such Indemnified Person by this
Declaration 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, in the case of the Property Trustee,
<PAGE>   57
                                                                              49

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 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 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.

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

                  SECTION 10.02. Indemnification and Compensation. (a) To the
fullest extent permitted by applicable law, the Sponsor shall indemnify and hold
harmless each Indemnified Person from and against any loss, damage or claim
incurred by such Indemnified Person 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 authority conferred on such Indemnified Person by this Declaration, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of gross
negligence (or, in the case of the Property Trustee, negligence) or willful
misconduct with respect to such acts or omissions.

                  (b) To the fullest extent permitted by applicable law,
expenses (including legal fees) incurred by an Indemnified Person in defending
any claim, demand, action, suit or proceeding shall, from time to time, be
advanced by the Sponsor prior to the final disposition of such claim,
<PAGE>   58
                                                                              50


demand, action, suit or proceeding upon receipt by the Sponsor of an undertaking
by or on behalf of the Indemnified Person to repay such amount if it shall be
determined that the Indemnified Person is not entitled to be indemnified as
authorized in Section 10.02(a).

                  (c) The Sponsor agrees to pay the Property Trustee and the
Delaware Trustee from time to time such compensation for all services rendered
by the Property Trustee and the Delaware Trustee hereunder as may be mutually
agreed upon in writing by the Sponsor and the Property Trustee or the Delaware
Trustee, as the case may be, and, except as otherwise expressly provided herein,
to reimburse the Property Trustee and the Delaware Trustee upon its or their
request for all reasonable expenses, disbursements and advances incurred or made
by the Property Trustee or the Delaware Trustee, as the case may be, in
accordance with the provisions of this Declaration, except any such expense,
disbursement or advance as may be attributable to its or their negligence or bad
faith.

                  SECTION 10.03. Outside Businesses. Any Covered Person, the
Sponsor, PWG, 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 business of the
Trust, and the Trust and the Holders of Securities shall have no rights by
virtue of this Declaration 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 business of the Trust, shall not be deemed wrongful or
improper. None of the Covered Persons, the Sponsor, PWG, 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, PWG, 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

                                                                              51

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.

                                   ARTICLE XI

                                   Accounting

                  SECTION 11.01. Fiscal Year. The fiscal year ("Fiscal Year") of
the Trust shall be the calendar year, or such other year as is required by the
Code.

                  SECTION 11.02. Certain Accounting Matters. (a) At all times
during the existence of the Trust, the Regular 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 and records of the Trust, together with a copy of this
Declaration and a certified copy of the Certificate of Trust, or any amendment
thereto, shall at all times be maintained at the principal office of the Trust
and shall be open for inspection by any Holder or its duly authorized
representative for any purpose reasonably related to its interest in the Trust
during normal business hours.

                  (b) The Regular Trustees shall, as soon as available after the
end of each Fiscal Year of the Trust, cause to be prepared and mailed to each
Holder of Securities unaudited financial statements of the Trust for such Fiscal
Year, prepared in accordance with generally accepted accounting principles;
provided that if the Trust is required to comply with the periodic reporting
requirements of Sections 13(a) or 15(d) of the Exchange Act, such financial
statements for such Fiscal Year shall be examined and reported on by a firm of
independent certified public

                                                                              52

accountants selected by the Regular Trustees (which firm may be the firm used by
the Sponsor).

                  (c) The Regular Trustees shall cause to be prepared and mailed
to each Holder of Securities an annual United States Federal income tax
information statement, on such form as is 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 Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

                  (d) The Regular Trustees shall cause to be prepared and filed
with the appropriate taxing authority an annual United States Federal income tax
return, on such form as is required by the Code, and any other annual income tax
returns required to be filed by the Regular Trustees on behalf of the Trust with
any state or local taxing authority, such returns to be filed as soon as
practicable after the end of each Fiscal Year of the Trust.

                  SECTION 11.03. Banking. The Regular Trustees shall maintain
one or more bank accounts in the name and for the sole benefit of the Trust;
provided, however, that all payments of funds in respect of the Debentures held
by the Property Trustee shall be made directly to the Property Account and no
other funds from the Trust shall be deposited in the Property Account. The sole
signatories for such accounts shall be designated by the Regular Trustees;
provided, however, that the Property Trustee shall designate the sole
signatories for the Property Account.

                  SECTION 11.04. Withholding. The Trust and the 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.
<PAGE>   61
                                                                              53

The Property Trustee shall file required forms with applicable jurisdictions
and, unless an exemption from withholding is properly established by a Holder,
the Property Trustee 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 overwithholding, Holders shall be limited to an action against the
applicable jurisdiction. If the amount to be withheld was not withheld from a
Distribution, the Property Trustee may reduce subsequent Distributions by the
amount of such withholding.

                                   ARTICLE XII

                             Amendments and Meetings

                  SECTION 12.01. Amendments. (a) Except as otherwise provided in
this Declaration or by any applicable terms of the Securities, this Declaration
may be amended by, and only by, a written instrument executed by a majority of
the Regular Trustees (or, if there are only two Regular Trustees, both Regular
Trustees); provided, however, that (i) no amendment to this Declaration shall be
made unless the Regular Trustees shall have obtained (A) either a ruling from
the Internal Revenue Service or a written unqualified opinion of nationally
recognized independent tax counsel experienced in such matters to the effect
that such amendment will not cause the Trust to be classified for United States
Federal income tax purposes as an association taxable as a corporation or a
partnership and to the effect that the Trust will continue to be treated as a
grantor trust for purposes of United States Federal income taxation and (B) a
written unqualified opinion of nationally recognized independent counsel
experienced in such matters to the effect that such amendment will not cause the
Trust to be an Investment Company which is required to be registered under the
Investment Company Act, (ii) if Securities are outstanding, any amendment which
would adversely affect the rights, privileges or preferences of any Holder of
Securities may be effected only after
<PAGE>   62
                                                                              54

satisfaction of such additional requirements as may be set forth in the terms of
such Securities, (iii) Section 4.02, Section 9.01(c) and this Section 12.01
shall not be amended without the consent of all Holders of the Securities, (iv)
no amendment which adversely affects the rights, powers and privileges of the
Property Trustee or the Delaware Trustee shall be made without the consent of
the Property Trustee or the Delaware Trustee, as the case may be, (v) Article IV
shall not be amended without the consent of the Sponsor, and (vi) the rights of
Holders of Common Securities under Article V to increase or decrease the number
of, and to appoint, replace or remove, Trustees shall not be amended without the
consent of each Holder of Common Securities.

                  (b) Notwithstanding Section 12.02(a)(ii), this Declaration may
be amended without the consent of the Holders of the Securities to (i) cure any
ambiguity, (ii) correct or supplement any provision in this Declaration that may
be defective or inconsistent with any other provision of this Declaration, (iii)
to add to the covenants, restrictions or obligations of the Sponsor, and (iv) to
conform to any changes in Rule 3a-7 or any change in interpretation or
application of Rule 3a-7 by the Commission, which amendment does not adversely
affect the rights, preferences or privileges of the Holders.

                  (c) The Regular Trustees shall promptly furnish to each of the
Property Trustee and the Delaware Trustee a copy of each amendment to this
Declaration.

                  SECTION 12.02. Meetings of the Holders of Securities; Action
by Written Consent. (a) Meetings of the Holders of Preferred Securities and/or
Common Securities may be called at any time by the Regular Trustees (or as
provided in the terms of the Securities) to consider and act on any matter on
which Holders of such class of Securities are entitled to act under the terms of
this Declaration, the terms of the Securities or the rules of any stock exchange
on which the Preferred Securities are listed or admitted for trading. The
Regular Trustees shall call a meeting of Holders of Preferred Securities or
Common Securities if directed to do so by Holders of at least 10% in liquidation
amount of such class of Securities. Such direction shall be
<PAGE>   63
                                                                              55

given by delivering to the Regular Trustees one or more notices in 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 specified Certificates shall be counted for purposes of
determining whether the required percentage set forth in the second sentence of
this paragraph has been met.

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

                  (i) Notice of any such meeting shall be given by mail to each
         Trustee and all the Holders of Securities having a right to vote
         thereat not less than seven days nor more than 60 days prior to the
         date of such meeting. Whenever a vote, consent or approval of the
         Holders of Securities is permitted or required under this Declaration
         or the rules of any stock exchange on which the 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 if a consent in writing setting forth the action so taken is
         signed by Holders of Securities owning not less than the minimum
         aggregate liquidation amount of Securities 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 Regular Trustees may specify that any written ballot
         submitted to the Holders of Securities for the purpose of taking any
         action without a meeting shall be returned to the Trust within the time
         specified by the Regular Trustees.

                  (ii) Each Holder of a Security may authorize any Person to act
         for it by proxy on all matters in which a
<PAGE>   64
                                                                              56

         Holder of a Security 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 Security executing it.
         Except as otherwise provided herein or in the terms of the Securities,
         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 Regular Trustees or by such other Person that the
         Regular Trustees may designate.

                  (iv) Unless otherwise provided in the Business Trust Act, this
         Declaration or the rules of any stock exchange on which the Preferred
         Securities are then listed or admitted for trading, the Regular
         Trustees, in their sole discretion, shall establish all other
         provisions relating to meetings of Holders of Securities, including
         notice of the time, place or purpose of any meeting at which any matter
         is to be voted on by any Holders of Securities, waiver of any such

                                                                               2


such interest payable unless otherwise stated. A Distribution will be made by
the Property Trustee only to the extent that interest payments are made in
respect of the Debentures held by the Property Trustee. The amount of
Distributions payable for any period will be computed on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a 30-day period
for which Distributions are computed, Distributions will be computed on the
basis of the actual number of days elapsed.

                  (b) Distributions on the Preferred Securities will be
cumulative, will accrue from December 9, 1996, and will be payable monthly in
arrears, on the first day of each month commencing on January 1, 1997, except as
otherwise described below, but only if and to the extent that interest payments
are made in respect of the Debentures held by the Property Trustee. So long as
PWG is not in default in the payment of interest on the Debentures, PWG shall
have the right under the Indenture for the Debentures to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not to exceed 60 consecutive monthly interest periods
(an "Extension Period"), provided, however, that an Extension Period may not
extend beyond the maturity of the Debentures. During any such Extension Period,
monthly Distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at the rate of 8.30% per annum, compounded
monthly . Prior to the termination of any such Extension Period, PWG may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 60 consecutive
monthly interest periods. Upon the termination of any Extension Period and the
payment of all amounts then due, PWG may commence a new Extension Period,
subject to the above requirements. Payments of accrued Distributions will be
payable to Holders of Preferred Securities as they appear on the books and
records of the Trust on the record date for the first interest payment date
occurring at or after the end of the Extension Period.

                  (c) Distributions on the Preferred Securities will be payable
promptly by the Property Trustee (or other Paying Agent) upon receipt of
immediately available funds to the Holders thereof as they appear on the books
and records
<PAGE>   76
                                                                               3


of the Trust on the relevant record dates. While the Preferred Securities remain
in book-entry only form, the relevant record dates shall be one Business Day
prior to the relevant Distribution date, and if the Preferred Securities are no
longer in book-entry only form, the relevant record dates will be the fifteenth
(15th) day of the month immediately preceding the month in which the relevant
Distribution date occurs, which record and payment dates correspond to the
record and interest payment dates for the Debentures. Distributions payable on
any Preferred Securities that are not punctually paid on any Distribution
payment date as a result of PWG having failed to make the corresponding interest
payment on the Debentures will forthwith cease to be payable to the Person in
whose name such Preferred Security is registered on the relevant record date,
and such defaulted Distribution will instead be payable to the Person in whose
name such Preferred Security is registered on the special record date
established by the Regular Trustees, which record date shall correspond to the
special record date or other specified date determined in accordance with the
Indenture; provided, however, that Distributions shall not be considered payable
on any Distribution payment date falling within an Extension Period unless PWG
has elected to make a full or partial payment of interest accrued on the
Debentures on such Distribution payment date. Subject to any applicable laws and
regulations and the provisions of the Declaration, each payment in respect of
the Preferred Securities will be made as described in paragraph 9 hereof. If any
date on which Distributions are payable on the Preferred 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 Business Day, in each case with the same force and effect
as if made on such date.

                  (d) All Distributions paid with respect to the Preferred
Securities and the Common Securities will be paid pro rata to the Holders
thereof entitled thereto. If an Event of Default has occurred and is continuing,
the Preferred Securities shall have a priority over the Common Securities with
respect to Distributions.
<PAGE>   77
                                                                               4


                  (e) In the event that there is any money or other property
held by or for the Trust that is not accounted for under the Declaration, such
money or property shall be distributed pro rata among the Holders of the
Preferred Securities and the Common Securities.

                  3. Liquidation Distribution upon Dissolution. In the event of
any voluntary or involuntary dissolution, winding-up or termination of the
Trust, the Holders of the Preferred Securities and the Common Securities at the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive pro rata solely out of the assets of the Trust available for
distribution to Holders of Preferred Securities and Common Securities after
satisfaction of liabilities to creditors, an amount equal to the aggregate of
the stated liquidation amount of $25 per Preferred Security and Common Security
plus accrued and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution"), unless, in connection with such
dissolution, winding-up or termination, and after satisfaction of liabilities to
creditors, Debentures in an aggregate principal amount equal to the aggregate
stated liquidation amount of such Preferred Securities and Common Securities,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid Distributions on such Preferred Securities and Common Securities, shall
be distributed pro rata to the Holders of the Preferred Securities and Common
Securities in exchange for such Securities.

                  If, upon any such dissolution, 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 Preferred Securities and the Common Securities
shall be paid, subject to the next paragraph, on a pro rata basis.

                  Holders of Common Securities will be entitled to receive
Liquidation Distributions upon any such dissolution pro rata with Holders of
Preferred Securities, except that, if an Event of Default has occurred and is
continuing, the Preferred Securities shall have a priority over the Common
Securities with respect to such Liquidation Distribution.

                                                                               5


                  4. Redemption and Distribution of Debentures. The Preferred
Securities and the Common Securities may only be redeemed if Debentures having
an aggregate principal amount equal to the aggregate liquidation amount of the
Preferred Securities and the Common Securities are repaid, redeemed or
distributed as set forth below:

                  (a) Upon the repayment of the Debentures, in whole or in part,
whether at maturity or upon redemption at any time or from time to time on or
after December 1, 2001, the proceeds of such repayment will be promptly applied
to redeem pro rata Preferred Securities and Common Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so repaid, upon not less than 30 nor more than 60 days notice, at a
redemption price of $25 per Preferred Security and Common Security plus an
amount equal to accrued and unpaid Distributions thereon to the date of
redemption, payable in cash (the "Redemption Price"). The date of any such
repayment of Preferred Securities and Common Securities shall be established to
coincide with the repayment date of the Debentures.

                  (b) If fewer than all the outstanding Preferred Securities and
Common Securities are to be so redeemed, the Preferred Securities and the Common
Securities will be redeemed pro rata, it being understood that Preferred
Securities held of record by a Clearing Agency or nominee will be redeemed as
described in paragraph 4(f)(ii) below. If a partial redemption would result in
the delisting of the Preferred Securities by any national securities exchange or
other organization on which the Preferred Securities are then listed, PWG
pursuant to the Indenture, will only redeem Debentures in whole and the Trust
will only redeem the Preferred Securities in whole.

                  (c) If, at any time, a Tax Event or an Investment Company
Event (each as hereinafter defined, and each a "Special Event") shall occur and
be continuing, the Regular Trustees shall, unless the Debentures are redeemed in
the limited circumstances described below, dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Property Trustee having
an aggregate principal amount equal to the aggregate stated liquidation amount
of, and
<PAGE>   79
                                                                               6


bearing accrued and unpaid interest equal to accrued and unpaid Distributions
on, and having the same record date for payment as, the Preferred Securities and
the Common Securities, to be distributed to the Holders of the Preferred
Securities and the Common Securities on a pro rata basis in liquidation of such
Holders' interests in the Trust, within 90 days following the occurrence of such
Special Event (the "90 Day Period"); provided, however, that in the case of the
occurrence of a Tax Event, as a condition of such dissolution and distribution,
the Regular Trustees shall have received an opinion of a nationally recognized
independent tax counsel experienced in such matters (a "No Recognition
Opinion"), which opinion may rely on any then applicable published revenue
rulings of the Internal Revenue Service, to the effect that the Holders of the
Preferred Securities will not recognize any gain or loss for United States
Federal income tax purposes as a result of the dissolution of the Trust and
distribution of Debentures; and provided further that, if at the time there is
available to PWG or the Regular Trustees, on behalf of the Trust, the
opportunity to eliminate, within the 90 Day Period, the Special Event by taking
some ministerial action, such as filing a form or making an election, or
pursuing some other similar reasonable measure that has no adverse effect on the
Trust, PWG or the Holders of the Preferred Securities (a "Ministerial Action"),
PWG or the Regular Trustees, on behalf of the Trust, will pursue such
Ministerial Action in lieu of dissolution.

                  If in the case of the occurrence of a Tax Event, (i) the
Regular Trustees have received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of a Tax Event, there is more than an insubstantial risk that PWG
would be precluded from deducting the interest on the Debentures for United
States Federal income tax purposes even if the Debentures were distributed to
the Holders of Preferred Securities and Common Securities in liquidation of such
Holder's interest in the Trust as described in this paragraph 4(c) or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, PWG shall have the right
at any time, upon not less than 30 nor more than 60 days notice, to redeem the
Debentures in whole
<PAGE>   80
                                                                               7


or in part for cash at the Redemption Price within 90 days following the
occurrence of such Tax Event, and, promptly following such redemption, Preferred
Securities and Common Securities with an aggregate liquidation amount equal to
the aggregate principal amount of the Debentures so redeemed will be redeemed by
the Trust at the Redemption Price on a pro rata basis; provided, however, that,
if at the time there is available to PWG or the Regular Trustees, on behalf of
the Trust, the opportunity to eliminate, within such 90 day period, the Tax
Event by taking some Ministerial Action, PWG or the Regular Trustees, on behalf
of the Trust, will pursue such measure in lieu of redemption; and provided
further that PWG shall have no right to redeem the Debentures while the Regular
Trustees, on behalf of the Trust, are pursuing such Ministerial Action. The
Common Securities will be redeemed pro rata with the Preferred Securities,
except that if an Event of Default under the Indenture has occurred and is
continuing, the Preferred Securities will have a priority over the Common
Securities with respect to payment of the Redemption Price.

                  "Tax Event" means that the Regular Trustees shall have
obtained an opinion of nationally recognized independent tax counsel experienced
in such matters (a "Dissolution Tax Opinion") to the effect that, on or after
December 4, 1996, as a result of (a) any amendment to, or change (including any
announced prospective change) in, the laws (or any regulations thereunder) of
the United States or any political subdivision or taxing authority thereof or
therein, (b) any amendment to, or change (including any announced prospective
change) in, an interpretation or application of any such laws or regulations by
any legislative body, court, governmental agency or regulatory authority
(including the enactment of any legislation and the publication of any judicial
decision or regulatory determination), (c) any interpretation or pronouncement
that provides for a position with respect to such laws or regulations that
differs from the theretofore generally accepted position or (d) any action taken
by any governmental agency or regulatory authority, which amendment or change is
enacted, promulgated, issued or effective or which interpretation or
pronouncement is issued or announced or which action is taken, in each case on
or after December 4, 1996, there is more than an insubstantial risk
<PAGE>   81
                                                                               8


that (i) the Trust is, or will be within 90 days of the date thereof, subject to
United States Federal income tax with respect to income accrued or received on
the Debentures, (ii) the Trust is, or will be within 90 days of the date
thereof, subject to more than a de minimis amount of other taxes, duties or
other governmental charges or (iii) interest payable by PWG to the Trust on the
Debentures is not, or within 90 days of the date thereof will not be, deductible
by PWG for United States Federal income tax purposes.

                  "Investment Company Event" means that the Regular Trustees
shall have received an opinion of nationally recognized independent counsel
experienced in practice under the Investment Company Act that, as a result of
the occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority (a "Change in 1940 Act Law"), there is more than
an insubstantial risk that the Trust is or will be considered an Investment
Company which is required to be registered under the Investment Company Act,
which Change in 1940 Act Law becomes effective on or after December 4, 1996.

                  On the date fixed for any distribution of Debentures, upon
dissolution of the Trust, (i) the Preferred Securities will no longer be deemed
to be outstanding, and (ii) certificates representing Preferred Securities will
be deemed to represent beneficial interests in 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 Preferred Securities until such certificates are presented to PWG or
its agent for transfer or reissuance.

                  (d) The Trust may not redeem fewer than all the outstanding
Preferred Securities unless all accrued and unpaid Distributions have been paid
on all Preferred Securities for all monthly Distribution periods terminating on
or prior to the date of redemption.

                  (e) If Debentures are distributed to Holders of the Preferred
Securities, PWG, pursuant to the terms of the Indenture, will use its best
efforts to have the Debentures
<PAGE>   82
                                                                               9


listed on the New York Stock Exchange or on such other exchange as the Preferred
Securities were listed immediately prior to the distribution of the Debentures.

                  (f)(i) Notice of any redemption of, or notice of distribution
of Debentures in exchange for, the Preferred Securities and the Common
Securities (a "Redemption/Distribution Notice") will be given by the Regular
Trustees on behalf of the Trust by mail to each Holder of Preferred Securities
and Common Securities to be redeemed or exchanged not less than 30 nor more than
60 days prior to the date fixed for redemption or exchange thereof. For purposes
of the calculation of the date of redemption or exchange and the dates on which
notices are given pursuant to this paragraph (f)(i), 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 Preferred Securities and Common
Securities. Each Redemption/Distribution Notice shall be addressed to the
Holders of Preferred Securities and Common Securities at the address of each
such Holder appearing in the books and records 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.

                  (ii) In the event that fewer than all the outstanding
Preferred Securities are to be redeemed, the Preferred Securities to be redeemed
will be redeemed pro rata from each Holder of Preferred Securities, it being
understood that, in respect of Preferred Securities registered in the name of
and held of record by DTC (or a successor Clearing Agency) or any other nominee,
the Preferred Securities will be redeemed from, and the distribution of the
proceeds of such redemption will be made to, each Clearing Agency Participant
(or person on whose behalf such nominee holds such securities) in accordance
with the procedures applied by such agency or nominee.

                  (iii) Subject to paragraph 9 hereof, if the Trust gives a
Redemption/Distribution Notice in respect of a redemption of Preferred
Securities as provided in this paragraph 4 (which notice will be irrevocable)
then
<PAGE>   83
                                                                              10


(A) while the Preferred Securities are in book-entry only form, by 12:00 noon,
New York City time, on the redemption date, provided that PWG has paid the
Property Trustee in immediately available funds a sufficient amount of cash in
connection with the related redemption or maturity of the Debentures, the
Property Trustee will deposit irrevocably with DTC (or any successor Clearing
Agency) funds sufficient to pay the applicable Redemption Price with respect to
the Preferred Securities and will give DTC (or any successor Clearing Agency)
irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Preferred Securities and (B) if the Preferred Securities are
issued in definitive form, and provided that PWG has paid the Property Trustee
in immediately available funds a sufficient amount of cash in connection with
the related redemption or maturity of the Debentures, the Property Trustee will
pay the relevant Redemption Price to the Holders of such Preferred Securities by
check mailed to the address of the relevant Holder appearing on the books and
records of the Trust on the redemption date. If a Redemption/Distribution Notice
shall have been given and funds deposited as required, if applicable, then
immediately prior to the close of business on the redemption date, Distributions
will cease to accrue on the Preferred Securities called for redemption, such
Preferred Securities will no longer be deemed to be outstanding and all rights
of Holders of such Preferred Securities so called for redemption will cease,
except the right of the Holders of such Preferred Securities to receive the
Redemption Price, but without interest on such Redemption Price. Neither the
Trustees nor the Trust shall be required to register or cause to be registered
the transfer of any Preferred Securities which have been so called for
redemption. If any date fixed for redemption of Preferred 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
falls in the next calendar year, such payment will 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 PWG fails to repay Debentures on maturity
or on the date fixed for redemption or if payment of the Redemption Price in
respect of Preferred Securities is improperly withheld or refused
<PAGE>   84
                                                                              11


and not paid either by the Property Trustee or, pursuant to the Preferred
Securities Guarantee, by PWG, Distributions on such Preferred Securities will
continue to accrue, from the original redemption date to the date of payment, in
which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the Redemption Price.

                  (iv) Redemption/Distribution Notices shall be sent by the
Regular Trustees on behalf of the Trust to DTC or its nominee (or any successor
Clearing Agency or its nominee) if the Global Certificates have been issued or,
if Definitive Preferred Security Certificates have been issued, to the Holders
of the Preferred Securities.

                  (v) Upon the date of dissolution of the Trust and distribution
of Debentures as a result of the occurrence of a Special Event, Preferred
Security Certificates shall be deemed to represent beneficial interests in the
Debentures so distributed, and the Preferred Securities will no longer be deemed
outstanding and may be canceled by the Regular Trustees. The Debentures so
distributed shall have an aggregate principal amount equal to the aggregate
liquidation amount of the Preferred Securities so distributed.

                  (vi) If a partial redemption of the Preferred Securities would
result in the delisting of the Preferred Securities by any national securities
exchange or other organization on which the Preferred Securities are then
listed, the Company pursuant to the Indenture will only redeem Debentures in
whole and, as a result, the Trust would only redeem the Preferred Securities in
whole.

                  (vii) Subject to the foregoing and applicable law (including,
without limitation, United States Federal securities laws), PWG or any of its
subsidiaries may at any time and from time to time purchase outstanding
Preferred Securities by tender, in the open market or by private agreement.

                  5. Voting Rights. (a) Except as provided under paragraph 5(b)
below and as otherwise required by law and
<PAGE>   85
                                                                              12


the Declaration, the Holders of the Preferred Securities will have no voting
rights.

                  (b) If any proposed amendment to the Declaration provides for,
or the Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than in connection
with the distribution of Debentures held by the Property Trustee, upon the
occurrence of a Special Event or in connection with the redemption of Preferred
Securities as a consequence of a redemption of Debentures, then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such amendment or proposal shall not be effective except with the
approval of the Holders of Securities representing 66-2/3% in liquidation amount
of such Securities; provided, however, that (A) if any amendment or proposal
referred to in clause (i) above would adversely affect only the Preferred
Securities or the Common Securities, then only the affected class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of 66-2/3% in liquidation amount
of such class of Securities and (B) amendments to the Declaration shall be
subject to such further requirements as are set forth in Sections 12.01 and
12.02 of the Declaration.

                  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, modification or termination of the Indenture or the Debentures, the
Property Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination. The
Property Trustee shall vote with respect to such amendment, modification or
termination as directed by a Majority in liquidation amount of the Securities
voting together as a single class; provided that where such amendment,
modification or termination of the Indenture requires the consent or vote of (1)
holders of Debentures representing a specified percentage greater than a
majority in principal amount of the Debentures or (2) each holder of Debentures
affected
<PAGE>   86
                                                                              13


thereby, the Property Trustee may only vote with respect to that amendment,
modification or termination as directed by, in the case of clause (1) above, the
vote of Holders of Securities representing such specified percentage of the
aggregate liquidation amount of the Securities, or, in the case of clause (2)
above, each Holder of Securities affected thereby; and provided further that the
Property Trustee shall be under no obligation to take any action in accordance
with the directions of the Holders of Securities unless the Property Trustee
shall have received, at the expense of the Sponsor, an opinion of nationally
recognized independent tax counsel recognized as expert in such matters to the
effect that the Trust will not be classified for United States Federal income
tax purposes as an association taxable as a corporation or a partnership on
account of such action and will be treated as a grantor trust for United States
Federal income tax purposes following such action.

                  Subject to Section 2.06 of the Declaration, and the provisions
of this and the next succeeding paragraph, the Holders of a Majority in
liquidation amount of the Preferred Securities, voting separately as a class,
shall have the right to (A) on behalf of all Holders of Preferred Securities,
waive any past default that is waivable under the Declaration (subject to, and
in accordance with, the Declaration) and (B) direct 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 the
Declaration, including the right to direct the Property Trustee, as the holder
of the Debentures, to (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or exercising any
trust or power conferred on the Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 6.06 of
the Indenture, or (iii) exercise any right to rescind or annul a declaration
that the principal of all the Debentures shall be due and payable; provided that
where the taking of any action under the Indenture requires the consent or vote
of (1) holders of Debentures representing a specified percentage greater than a
majority in principal amount of the Debentures or (2) each holder of Debentures
affected thereby, the Property Trustee may only take such action if directed by,
in the case of clause (1)
<PAGE>   87
                                                                              14


above, the vote of Holders of Preferred Securities representing such specified
percentage of the aggregate liquidation amount of the Preferred Securities, or,
in the case of clause (2) above, each Holder of Preferred Securities affected
thereby. The Property Trustee shall not revoke any action previously authorized
or approved by a vote of the Holders of the Preferred Securities. Other than
with respect to directing the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee or the Debenture
Trustee as set forth above, the Property Trustee shall be under no obligation to
take any of the foregoing actions at the direction of the Holders of Preferred
Securities unless the Property Trustee shall have received, at the expense of
the Sponsor, an opinion of nationally recognized independent tax counsel
recognized as expert in such matters to the effect that the Trust will not be
classified for United States Federal income tax purposes as an association
taxable as a corporation or a partnership on account of such action and will be
treated as a grantor trust for United States federal income tax purposes
following such action. If the Property Trustee fails to enforce its rights under
the Declaration (including, without limitation, its rights, powers and
privileges as a holder of the Debentures under the Indenture), any Holder of
Preferred Securities may, to the extent permitted by law, after a period of 30
days has elapsed from such Holder's written request to the Property Trustee to
enforce such rights, institute a legal proceeding directed against PWG to
enforce the Property Trustee's rights under the Declaration, without first
instituting a legal proceeding against the Property Trustee or any other Person.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of PWG to pay interest
or principal on the Debentures on the date such interest or principal is
otherwise payable (or in the case of redemption, the redemption date), then a
Holder of Preferred Securities may directly institute suit against PWG 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 Preferred Securities held by such Holder on or after the respective due
date specified in the Debentures. The Holders of Preferred Securities will not
be able to exercise directly against PWG
<PAGE>   88
                                                                              15


any other remedy available to the Holders of the Debentures unless the Property
Trustee first fails to do so.

                  A waiver of an Indenture Event of Default by the Property
Trustee at the direction of the Holders of the Preferred Securities will
constitute a waiver of the corresponding Event of Default under the Declaration
in respect of the Securities.

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

                  No vote or consent of the Holders of Preferred Securities will
be required for the Trust to redeem and cancel Preferred Securities in
accordance with the Declaration.

                  Notwithstanding that Holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities at such time that are owned by PWG or by any entity
directly or indirectly controlling or controlled by or under direct or indirect
common control with PWG shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.

                  Holders of the Preferred Securities will have no rights to
increase or decrease the number of Trustees or to appoint, remove or replace a
Trustee, which voting rights
<PAGE>   89
                                                                              16


are vested exclusively in the Holders of the Common Securities.

                  6. Pro Rata Treatment. A reference in these terms of the
Preferred Securities to any payment, distribution or treatment as being "pro
rata" shall mean pro rata to each Holder of Securities according to the
aggregate liquidation amount of the Securities held by the relevant Holder in
relation to the aggregate liquidation amount of all Securities outstanding
unless, in relation to a payment, an Event of Default has occurred and is
continuing, in which case any funds available to make such payment shall be paid
first to each Holder of the Preferred Securities pro rata according to the
aggregate liquidation amount of Preferred Securities held by the relevant Holder
relative to the aggregate liquidation amount of all Preferred Securities
outstanding, and only after satisfaction of all amounts owed to the Holders of
the Preferred Securities, to each Holder of Common Securities pro rata according
to the aggregate liquidation amount of Common Securities held by the relevant
Holder relative to the aggregate liquidation amount of all Common Securities
outstanding.

                  7. Ranking. The Preferred Securities rank pari passu and
payment thereon will be made pro rata with the Common Securities except that
where an Event of Default occurs and is continuing, the rights of Holders of
Preferred Securities to payment in respect of Distributions and payments upon
liquidation, redemption or otherwise rank in priority to the rights of Holders
of the Common Securities.

                  8. Mergers, Consolidations or Amalgamations. The Trust may not
consolidate, amalgamate, merge with or into, or be replaced by, or sell,
transfer or lease all or substantially all its properties and assets to, any
Person.

                  9. Transfer, Exchange, Method of Payments. Payment of
Distributions and payments on redemption of the Preferred Securities will be
payable, the transfer of the Preferred Securities will be registrable, and
Preferred Securities will be exchangeable for Preferred Securities of other
denominations of a like aggregate liquidation amount, at the principal corporate
trust office of the Property Trustee in The City of New York; provided that
payment of

                                                                              17


Distributions may be made at the option of the Regular Trustees on behalf of the
Trust by check mailed to the address of the Persons entitled thereto and that
the payment on redemption of any Preferred Security will be made only upon
surrender of such Preferred Security to the Property Trustee.

                  10. Acceptance of Indenture and Preferred Guarantee. Each
Holder of Preferred Securities, by the acceptance thereof, agrees to the
provisions of (i) the Preferred Guarantee, including the subordination
provisions thereof and (ii) the Indenture and the Debentures, including the
subordination provisions of the Indenture.

                  11. No Preemptive Rights. The Holders of Preferred Securities
shall have no preemptive rights to subscribe to any additional Preferred
Securities or Common Securities.


                  12. Miscellaneous. These terms shall constitute a part of the
Declaration. The Trust will provide a copy of the Declaration and the Indenture
to a Holder without charge on written request to the Trust at its principal
place of business.

                                    TERMS OF
                                COMMON SECURITIES


                  Pursuant to Section 7.01 of the Amended and Restated
Declaration of Trust of PWG Capital Trust I dated as of December 9, 1996 (as
amended from time to time, the "Declaration"), the designations, rights,
privileges, restrictions, preferences and other terms and provisions of the
Common Securities are set forth below (each capitalized term used but not
defined herein having the meaning set forth in the Declaration):

                  1. Designation and Number. Common Securities of the Trust with
an aggregate liquidation amount in the assets of the Trust of up to Six Million
Two Hundred Twenty Four Thousand Two Hundred Fifty Dollars ($6,224,250)
(including up to Eight Hundred Eleven Thousand Eight Hundred Seventy Five
Dollars ($811,875) issuable upon exercise of the overallotment option set forth
in the Underwriting Agreement) and a liquidation amount in the assets of the
Trust of $25 per Common Security are hereby designated as "8.30% Common Trust
Securities". The Common Security Certificates evidencing the Common Securities
shall be substantially in the form attached hereto as Annex I, with such changes
and additions thereto or deletions therefrom as may be required by ordinary
usage, custom or practice. The Common Securities are to be issued and sold to
Paine Webber Group Inc. ("PWG"). In connection with the issuance and sale of the
Preferred Securities and the Common Securities, the Trust will purchase, as
trust assets, Debentures of PWG having an aggregate principal amount equal to
the aggregate liquidation amount of the Preferred Securities and the Common
Securities so issued, and bearing interest at an annual rate equal to the annual
Distribution rate on the Preferred Securities and the Common Securities and
having payment and redemption provisions which correspond to the payment and
redemption provisions of the Preferred Securities and the Common Securities.

                  2. Distributions. (a) Distributions payable on each Common
Security will be fixed at a rate per annum of 8.30% (the "Coupon Rate") of the
stated liquidation amount of $25 per Common Security. Distributions in arrears
for more than one month will bear interest at the rate per annum of 8.30%
thereof (to the extent permitted by applicable law), compounded monthly. The
term "Distributions" as used
<PAGE>   97
                                                                               2


in these terms means such periodic cash distributions and any such interest
payable unless otherwise stated. A Distribution will be made by the Property
Trustee only to the extent that interest payments are made in respect of the
Debentures held by the Property Trustee. The amount of Distributions payable for
any period will be computed on the basis of a 360-day year of twelve 30-day
months, and for any Distribution period shorter than a 30-day period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed.

                  (b) Distributions on the Common Securities will be cumulative,
will accrue from December 9, 1996, and will be payable monthly in arrears, on
the first day of each month, commencing on January 1, 1997, except as otherwise
described below, but only if and to the extent that interest payments are made
in respect of the Debentures held by the Property Trustee. So long as PWG is not
in default in the payment of interest on the Debentures, PWG shall have the
right under the Indenture for the Debentures to defer payments of interest by
extending the interest payment period from time to time on the Debentures for a
period not to exceed 60 consecutive monthly interest periods (each, an
"Extension Period"), provided, however, that an Extension Period may not extend
beyond the maturity of the Debentures. During any such Extension Period, monthly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the rate of 8.30% per annum, compounded monthly.
Prior to the termination of any such Extension Period, PWG may further extend
such Extension Period; provided that such Extension Period, together with all
such previous and further extensions thereof, may not exceed 60 consecutive
monthly interest periods. Upon the termination of any Extension Period and the
payment of all amounts then due, PWG may commence a new Extension Period,
subject to the above requirements. Payments of accrued Distributions will be
payable to Holders of Common Securities as they appear on the books and records
of the Trust on the record date for the first interest payment date occurring at
or after the end of the Extension Period.

                  (c) Distributions on the Common Securities will be payable
promptly by the Property Trustee (or other Paying Agent) upon receipt of
immediately available funds to the
<PAGE>   98
                                                                               3


Holders thereof as they appear on the books and records of the Trust on the
relevant record dates which will be one Business Day prior to the relevant
Distribution date unless the Preferred Securities are no longer in book-entry
only form, in which event the relevant record dates will be the fifteenth (15th)
day of the month immediately preceding the month in which the relevant
Distribution date occurs, which record and payment dates correspond to the
record and interest payment dates for the Debentures. Distributions payable on
any Common Securities that are not punctually paid on any Distribution date as a
result of PWG having failed to make the corresponding interest payment on the
Debentures will forthwith cease to be payable to the Person in whose name such
Common Security is registered on the relevant record date, and such defaulted
Distribution will instead be payable to the Person in whose name such Common
Security is registered on the special record date established by the Regular
Trustees, which record date shall correspond to the special record date or other
specified date determined in accordance with the Indenture; provided, however,
that Distributions shall not be considered payable on any Distribution payment
date falling within an Extension Period unless PWG has elected to make a full or
partial payment of interest accrued on the Debentures on such Distribution
payment date. Subject to any applicable laws and regulations and the provisions
of the Declaration, each payment in respect of the Common Securities will be
made as described in paragraph 9 hereof. If any date on which Distributions are
payable on the Common 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 Business Day, in
each case with the same force and effect as if made on such date.

                  (d) All Distributions paid with respect to the Common
Securities and the Preferred Securities will be paid pro rata to the Holders
thereof entitled thereto. If an Event of Default has occurred and is continuing,
the Preferred Securities shall have a priority over the Common Securities with
respect to Distributions.
<PAGE>   99
                                                                               4


                  (e) In the event that there is any money or other property
held by or for the Trust that is not accounted for under the Declaration, such
money or property shall be distributed pro rata among the Holders of the
Preferred Securities and the Common Securities.

                  3. Liquidation Distribution Upon Dissolution. In the event of
any voluntary or involuntary dissolution, winding-up or termination of the
Trust, the Holders of the Preferred Securities and Common Securities at the date
of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive pro rata solely out of the assets of the Trust available for
distribution to Holders of Preferred Securities and the Common Securities, after
satisfaction of liabilities to creditors, an amount equal to the aggregate of
the stated liquidation amount of $25 per Preferred Security and Common Security
plus accrued and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution"), unless, in connection with such
dissolution, winding-up or termination, and after satisfaction of liabilities to
creditors, Debentures in an aggregate principal amount equal to the aggregate
stated liquidation amount of such Preferred Securities and Common Securities,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid Distributions on such Preferred Securities and Common Securities, shall
be distributed pro rata to the Holders of the Preferred Securities and Common
Securities in exchange for such Securities.

                  If, upon any such dissolution, 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 Preferred Securities and the Common Securities
shall be paid, subject to the next paragraph, on a pro rata basis.

                  Holders of Common Securities will be entitled to receive
Liquidation Distributions upon any such dissolution pro rata with Holders of
Preferred Securities, except that, if an Event of Default has occurred and is
continuing, the Preferred Securities shall have a priority over the Common
Securities with respect to such Liquidation Distribution.

                  4. Redemption and Distribution of Debentures. The Preferred
Securities and the Common Securities may only be redeemed if Debentures having
an aggregate principal amount equal to the aggregate liquidation amount of the
Preferred Securities and the Common Securities are repaid, redeemed or
distributed as set forth below:

                  (a) Upon the repayment of the Debentures, in whole or in part,
whether at maturity or upon redemption at any time or from time to time on or
after December 1, 2001, the proceeds of such repayment will be promptly applied
to redeem pro rata Preferred Securities and Common Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so repaid, upon not less than 30 nor more than 60 days notice, at a
redemption price of $25 per Preferred Security and Common Security plus an
amount equal to accrued and unpaid Distributions thereon to the date of
redemption, payable in cash (the "Redemption Price"). The date of any such
repayment of Preferred Securities and Common Securities shall be established to
coincide with the repayment or redemption date of the Debentures.

                  (b) If fewer than all the outstanding Preferred Securities and
Common Securities are to be so redeemed, the Preferred Securities and the Common
Securities will be redeemed pro rata and, with respect to the Common Securities
to be redeemed, as described in paragraph 4(e)(ii) below. If a partial
redemption would result in the delisting of the Preferred Securities by any
national securities exchange or other organization on which the Preferred
Securities are then listed, PWG, pursuant to the Indenture, will only redeem
Debentures in whole and the Trust will only redeem the Common Securities in
whole.

                  (c) If, at any time, a Tax Event or an Investment Company
Event (each, as hereinafter defined and, each, a "Special Event") shall occur
and be continuing, the Regular Trustees shall, unless the Debentures are
redeemed in the limited circumstances described below, dissolve the Trust and,
after satisfaction of creditors, cause Debentures held by the Property Trustee
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, and bearing accrued and unpaid interest equal to accrued and
<PAGE>   101
                                                                               6


unpaid Distributions on, and having the same record date for payment as, the
Preferred Securities and the Common Securities, to be distributed to the Holders
of the Preferred Securities and the Common Securities on a pro rata basis in
liquidation of such Holders' interests in the Trust, within 90 days following
the occurrence of such Special Event (the "90 Day Period"); provided, however,
that in the case of the occurrence of a Tax Event, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on any then
applicable published revenue rulings of the Internal Revenue Service, to the
effect that the Holders of the Preferred Securities will not recognize any gain
or loss for United States Federal income tax purposes as a result of the
dissolution of the Trust and distribution of Debentures; and provided further
that, if at the time there is available to PWG or the Regular Trustees, on
behalf of the Trust, the opportunity to eliminate, within such 90 Day Period,
the Special Event by taking some ministerial action, such as filing a form or
making an election, or pursuing some other similar reasonable measure that has
no adverse effect on the Trust, PWG or the Holders of the Preferred Securities
(a "Ministerial Action"), PWG or the Regular Trustees, on behalf of the Trust,
will pursue such Ministerial Action in lieu of dissolution.

                  If in the case of the occurrence of a Tax Event, (i) the
Regular Trustees have received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of a Tax Event, there is more than an insubstantial risk that PWG
would be precluded from deducting the interest on the Debentures for United
States Federal income tax purposes even if the Debentures were distributed to
the Holders of Preferred Securities and Common Securities in liquidation of such
Holders' interest in the Trust as described in this paragraph 4(c) or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, PWG shall have the right
at any time, upon not less than 30 nor more than 60 days notice, to redeem the
Debentures in whole or in part for cash at the Redemption Price within 90 days

                                                                               7


following the occurrence of such Tax Event, and, promptly following such
redemption, Preferred Securities and Common Securities with an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
redeemed will be redeemed by the Trust at the Redemption Price on a pro rata
basis; provided, however, that, if at the time there is available to PWG or the
Regular Trustees on behalf of the Trust, the opportunity to eliminate, within
such 90 Day Period, the Tax Event by taking some Ministerial Action, PWG or the
Holders of the Preferred Securities, PWG or the Regular Trustees, on behalf of
the Trust, will pursue such measure in lieu of redemption; and provided further,
that PWG shall have no right to redeem the Debentures while the Regular
Trustees, on behalf of the Trust, are pursuing such Ministerial Action. The
Common Securities will be redeemed pro rata with the Preferred Securities,
except that if an Event of Default under the Indenture has occurred and is
continuing, the Preferred Securities will have a priority over the Common
Securities with respect to payment of the Redemption Price.

                  "Tax Event" means that the Regular Trustees shall have
obtained an opinion of nationally recognized independent tax counsel experienced
in such matters (a "Dissolution Tax Opinion") to the effect that, on or after
December 4, 1996, as a result of (a) any amendment to, or change (including any
announced prospective change) in, the laws (or any regulations thereunder) of
the United States or any political subdivision or taxing authority thereof or
therein, (b) any amendment to, or change (including any announced prospective
change) in, an interpretation or application of any such laws or regulations by
any legislative body, court, governmental agency or regulatory authority
(including the enactment of any legislation and the publication of any judicial
decision or regulatory determination), (c) any interpretation or pronouncement
that provides for a position with respect to such laws or regulations that
differs from the theretofore generally accepted position or (d) any action taken
by any governmental agency or regulatory authority, which amendment or change is
enacted, promulgated, issued or effective or which interpretation or
pronouncement is issued or announced or which action is taken, in each case on
or after December 4, 1996, there is more than an insubstantial risk
<PAGE>   103
                                                                               8


that (i) the Trust is, or will be within 90 days of the date thereof, subject to
United States Federal income tax with respect to income accrued or received on
the Debentures, (ii) the Trust is, or will be within 90 days of the date
thereof, subject to more than a de minimis amount of taxes, duties or other
governmental charges or (iii) interest payable by PWG to the Trust on the
Debentures is not, or within 90 days of the date thereof will not be, deductible
by PWG for United States Federal income tax purposes.

                  "Investment Company Event" means that the Regular Trustees
shall have received an opinion of nationally recognized independent counsel
experienced in practice under the Investment Company Act that, as a result of
the occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority (a "Change in 1940 Act Law"), there is more than
an insubstantial risk that the Trust is or will be considered an Investment
Company which is required to be registered under the Investment Company Act,
which Change in 1940 Act Law becomes effective on or after December 4, 1996.

                  On the date fixed for any distribution of Debentures, upon
dissolution of the Trust, (i) the Common Securities will no longer be deemed to
be outstanding and (ii) any certificates representing Common Securities will be
deemed to represent beneficial interests in 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 Common
Securities until such certificates are presented to PWG or its agent for
transfer or reissuance.

                  (d) The Trust may not redeem fewer than all the outstanding
Common Securities unless all accrued and unpaid Distributions have been paid on
all Common Securities for all monthly Distribution periods terminating on or
prior to the date of redemption.

                  (e)(i) Notice of any redemption of, or notice of distribution
of Debentures in exchange for, the Preferred Securities and the Common
Securities (a "Redemption/Distribution Notice") will be given by the
<PAGE>   104
                                                                               9


Regular Trustees on behalf of the Trust by mail to each Holder of Preferred
Securities and Common Securities to be redeemed or exchanged not less than 30
nor more than 60 days prior to the date fixed for redemption or exchange
thereof. For purposes of the calculation of the date of redemption or exchange
and the dates on which notices are given pursuant to this paragraph (e)(i), 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
Preferred Securities and Common Securities. Each Redemption/ Distribution Notice
shall be addressed to the Holders of Preferred Securities and Common Securities
at the address of each such Holder appearing in the books and records 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.

                  (ii) In the event that fewer than all the outstanding Common
Securities are to be redeemed, the Common Securities to be redeemed will be
redeemed pro rata from each Holder of Common Securities (subject to adjustment
to eliminate fractional Common Securities).

                  (iii) If the Trust gives a Redemption/Distribution Notice in
respect of a redemption of Common Securities as provided in this paragraph 4
(which notice will be irrevocable), then immediately prior to the close of
business on the redemption date, provided that PWG has paid to the Property
Trustee in immediately available funds a sufficient amount of cash in connection
with the related redemption or maturity of the Debentures, Distributions will
cease to accrue on the Common Securities called for redemption, such Common
Securities will no longer be deemed to be outstanding and all rights of Holders
of such Common Securities so called for redemption will cease, except the right
of the Holders of such Common Securities to receive the Redemption Price, but
without interest on such Redemption Price. Neither the Trustees nor the Trust
shall be required to register or cause to be registered the transfer of any
Common Securities which have been so called for redemption. If any date fixed
for redemption of Common Securities is not a Business Day, then payment of the
<PAGE>   105
                                                                              10

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 falls in the next calendar
year, such payment will 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 Common Securities
is improperly withheld or refused and not paid by the Property Trustee,
Distributions on such Common Securities will continue to accrue, from the
original redemption date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the Redemption Price.

                  (iv) Redemption/Distribution Notices shall be sent by the
Regular Trustees on behalf of the Trust to the Holders of the Common Securities.

                  (v) Upon the date of dissolution of the Trust and distribution
of Debentures as a result of the occurrence of a Special Event, Common Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so distributed, and the Common Securities will no longer be deemed outstanding
and may be canceled by the Regular Trustees. The Debentures so distributed shall
have an aggregate principal amount equal to the aggregate liquidation amount of
the Common Securities so distributed.

                  5. Voting Rights. (a) Except as provided under paragraph 5(b)
below and as otherwise required by law and the Declaration, the Holders of the
Common Securities will have no voting rights.

                  (b) Holders of Common Securities have the sole right under the
Declaration to increase or decrease the number of Trustees, and to appoint,
remove or replace a Trustee, any such increase, decrease, appointment, removal
or replacement to be approved by Holders of Common Securities representing a
Majority in liquidation amount of the Common Securities.

                  If any proposed amendment to the Declaration provides for, or
the Regular Trustees otherwise propose to
<PAGE>   106
                                                                              11


effect, (i) any action that would adversely affect the powers, preferences or
special rights of the Securities, whether by way of amendment to the Declaration
or otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than in connection with the distribution of Debentures held by the
Property Trustee, upon the occurrence of a Special Event or in connection with
the redemption of Common Securities as a consequence of a redemption of
Debentures, then the Holders of outstanding Securities will be entitled to vote
on such amendment or proposal as a class and such amendment or proposal shall
not be effective except with the approval of the Holders of Securities
representing 66-2/3% in liquidation amount of such Securities; provided,
however, that (A) if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or the Common Securities,
then only the affected class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of 66-2/3% in liquidation amount of such class of Securities, (B) the
rights of Holders of Common Securities under Article V of the Declaration to
increase or decrease the number of, and to appoint, replace or remove, Trustees
shall not be amended without the consent of each Holder of Common Securities,
and (C) amendments to the Declaration shall be subject to such further
requirements as are set forth in Sections 12.01 and 12.02 of the Declaration.

                  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, modification or termination of the Indenture or the Debentures, the
Property Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination. The
Property Trustee shall vote with respect to such amendment, modification or
termination as directed by a Majority in liquidation amount of the Securities
voting together as a single class; provided that where such amendment,
modification or termination of the Indenture requires the consent or vote of (1)
holders of Debentures representing a specified percentage greater than a
majority in principal amount of the Debentures or (2) each holder of Debentures
affected thereby, the Property Trustee may vote only with respect to
<PAGE>   107
                                                                              12


that amendment, modification or termination as directed by, in the case of
clause (1) above, the vote of Holders of Securities representing such specified
percentage of the aggregate liquidation amount of the Securities, or, in the
case of clause (2) above, each Holder of Securities affected thereby; and
provided, further, that the Property Trustee shall be under no obligation to
take any action in accordance with the directions of the Holders of the
Securities unless the Property Trustee shall have received, at the expense of
the Sponsor, an opinion of nationally recognized independent tax counsel
recognized as an expert in such matters to the effect that the Trust will not be
classified for United States Federal income tax purposes as an association
taxable as a corporation or a partnership on account of such action and will be
treated as a grantor trust for United States Federal income tax purposes
following such action.

                  Subject to Section 2.06 of the Declaration and the provisions
of this and the next succeeding paragraph, the Holders of a Majority in
liquidation amount of the Common Securities, voting separately as a class, shall
have the right to (A) on behalf of all Holders of Common Securities, waive any
past default that is waivable under the Declaration (subject to, and in
accordance with, the Declaration) and (B) direct 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 the
Declaration, including the right to direct the Property Trustee, as holder of
the Debentures, to (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or exercising any
trust or power conferred on the Debenture Trustee with respect to the
Debentures, (ii) waive any past default and its consequences that is waivable
under Section 6.06 of the Indenture, or (iii) exercise any right to rescind or
annul a declaration that the principal of all the Debentures shall be due and
payable; provided that where the taking of any action under the Indenture
requires the consent or vote of (1) holders of Debentures representing a
specified percentage greater than a majority in principal amount of the
Debentures or (e) each holder of Debentures affected thereby, the Property
Trustee may take such action only if directed by, in the case of
<PAGE>   108
                                                                              13


clause (1) above, the vote of Holders of Common Securities representing such
specified percentage of the aggregate liquidation amount of the Common
Securities, or, in the case of clause (2) above, each Holder of Common
Securities affected thereby. Pursuant to this paragraph, the Property Trustee
shall not revoke, or take any action inconsistent with, any action previously
authorized or approved by a vote of the Holders of the Preferred Securities, and
shall not take any action in accordance with the direction of the Holders of the
Common Securities under this paragraph if the action is prejudicial to the
Holders of Preferred Securities. Other than with respect to directing the time,
method and place of conducting any proceeding for any remedy available to the
Property Trustee or the Debenture Trustee as set forth above, the Property
Trustee shall be under no obligation to take any of the foregoing actions at the
direction of the Holders of Common Securities unless the Property Trustee shall
have received, at the expense of the Sponsor, an opinion of nationally
recognized independent tax counsel recognized as expert in such matters to the
effect that the Trust will not be classified for United States Federal income
tax purposes as an association taxable as a corporation or a partnership on
account of such action and will be treated as a grantor trust for United States
income tax purposes following such action.

                  Notwithstanding any other provision of these terms, each
Holder of Common Securities will be deemed to have waived any Event of Default
with respect to the Common Securities and its consequences until all Events of
Default with respect to the Preferred Securities have been cured, waived by the
Holders of Preferred Securities as provided in the Declaration or otherwise
eliminated, and until all Events of Default with respect to the Preferred
Securities have been so cured, waived by the Holders of Preferred Securities or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Property Trustee in
accordance with the terms of the Declaration or of the Securities. In the event
that any Event of Default with respect to the Preferred Securities is waived by
the Holders of Preferred Securities as provided in the Declaration, the Holders
of Common Securities agree that
<PAGE>   109
                                                                              14


such waiver shall also constitute the waiver of such Event of Default with
respect to the Common Securities for all purposes under the Declaration without
any further act, vote or consent of the Holders of the Common Securities.

                  A waiver of an Indenture Event of Default by the Property
Trustee at the direction of the Holders of the Preferred Securities will
constitute a waiver of the corresponding Event of Default under the Declaration
in respect of the Securities.

                  Any required approval 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 of the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Common Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents.

                  No vote or consent of the Holders of Common Securities will be
required for the Trust to redeem and cancel Common Securities in accordance with
the Declaration.

                  6. Pro Rata Treatment. A reference in these terms of the
Common Securities to any payment, distribution or treatment as being "pro rata"
shall mean pro rata to each Holder of Securities according to the aggregate
liquidation amount of the Securities held by the relevant Holder in relation to
the aggregate liquidation amount of all Securities outstanding unless, in
relation to a payment, an Event of Default has occurred and is continuing, in
which case any funds available to make such payment shall be paid first to each
Holder of the Preferred Securities pro rata according to the aggregate
liquidation amount of Preferred Securities held by the relevant Holder relative
to the
<PAGE>   110
                                                                              15

aggregate liquidation amount of all Preferred Securities outstanding, and only
after satisfaction of all amounts owed to the Holders of the Preferred
Securities, to each Holder of Common Securities pro rata according to the
aggregate liquidation amount of Common Securities held by the relevant Holder
relative to the aggregate liquidation amount of all Common Securities
outstanding.

                  7. Ranking. The Common Securities rank pari passu and payment
thereon will be made pro rata with the Preferred Securities except that where an
Event of Default occurs and is continuing, the rights of Holders of Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption or otherwise are subordinate to the rights of Holders of the
Preferred Securities.

                  8. Mergers, Consolidations or Amalgamations. The Trust may not
consolidate, amalgamate, merge with or into, or be replaced by, or sell,
transfer or lease all or substantially all its properties and assets to, any
Person.

                  9. Transfers, Exchanges, Method Payments. Payment of
Distributions and payments on redemption of the Common Securities will be
payable, the transfer of the Common Securities will be registrable, and Common
Securities will be exchangeable for Common Securities of other denominations of
a like aggregate liquidation amount, at the principal corporate trust office of
the Property Trustee in The City of New York; provided that payment of
Distributions may be made at the option of the Regular Trustees on behalf of the
Trust by check mailed to the address of the Persons entitled thereto and that
the payment on redemption of any Common Security will be made only upon
surrender of such Common Security to the Property Trustee. Notwithstanding the
foregoing, transfers of Common Securities are subject to conditions set forth in
Section 9.01(c) of the Declaration.

                  10. Acceptance of Indenture. Each Holder of Common Securities,
by the acceptance thereof, agrees to the provisions of the Indenture and the
Debentures, including the subordination provisions thereof.
<PAGE>   111
                                                                              16

                  11. No Preemptive Rights. The Holders of Common Securities
shall have no preemptive rights to subscribe to any additional Common Securities
or Preferred Securities.

                  12. Miscellaneous. These terms shall constitute a part of the
Declaration. The Trust will provide a copy of the Declaration and the Indenture
to a Holder without charge on written request to the Trust at its principal
place of business.

                  (liquidation amount $25 per Common Security)


                  PWG Capital Trust I, a business trust formed under the laws of
the State of Delaware (the "Trust"), hereby certifies that Paine Webber Group
Inc. (the "Holder") is the registered owner of                common securities

provided in the Indenture.
