every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or an Event of Default with respect to the Preferred
Securities or impair any right consequent thereon. Any waiver by the Holders of
the Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holders of the Common Securities.

       (b) The Holders of a Majority in liquidation amount of the Common
Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

             (i) is not waivable under the Indenture, except where the Holders
       of the Common Securities are deemed to have waived such Event of Default
       under this Declaration as provided above in Section 2.06(a) or below in
       this Section 2.06(b), the Event of Default under this Declaration shall
       also not be waivable; or

             (ii) requires the consent or vote of a Super Majority to be waived,
       except where the Holders of the Common Securities are deemed to have
       waived such Event of Default under this Declaration as provided above in
       Section 2.06(a) or below in this Section 2.06(b), the Event of Default
       under this Declaration may only be waived by the vote of the Holders of
       at least the proportion in aggregate liquidation amount of the Common
       Securities that the relevant Super Majority represents of the aggregate
       principal amount of the Debentures outstanding;

provided, further, that the Holders of Common Securities will be deemed to have
waived any such Event of Default and all Events of Defaults with respect to the
Common Securities and their consequences until all Events of Default with
respect to the Preferred Securities have been cured, waived or otherwise
eliminated, and until such Events of Default 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 the Securities. The foregoing provisions of this
Section 2.06(b) shall be in lieu of ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the
Trust Indenture Act and such ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. 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 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 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


                                       11
<PAGE>

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) A waiver of an Event of Default under the Indenture by the Property
Trustee, at the direction of the Holders of Preferred Securities, constitutes a
waiver of the corresponding Event of Default under this Declaration. The
foregoing provisions of this Section 2.06(c) shall be in lieu of ss.
316(a)(1)(B) of the Trust Indenture Act and such ss. 316(a)(1)(B) of the Trust
Indenture Act is hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.

        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 ss. 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 ss. 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 ss. 312(b) of the Trust Indenture Act.

       (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

       436(g)(2) under the Securities Act, at least investment grade;

             (ii) engage in such ministerial activities as shall be necessary or
       appropriate to effect promptly the redemption of the Preferred Securities

             (iii) upon notice of distribution issued by the Regular Trustees in
       accordance with the terms of the Preferred Securities and the Common

       the Holder of Common Securities to distribute the Debentures to Holders
       of Securities and dissolve the Trust; 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 Default occurs and is continuing, the Property Trustee, subject
       to Section 3.10(e), 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.

                                       18
<PAGE>

       (e) If an Event of Default has occurred and is continuing, then the
Holders of a Majority in liquidation amount of the Preferred Securities will
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Property Trustee or to direct the exercise of
any trust or power conferred upon the Property Trustee under this Declaration,
including the right to direct the Property Trustee to exercise the remedies
available to it as a holder of the Debentures. If the Property Trustee fails to
enforce its rights under the Debentures, a Holder of Preferred Securities, to
the extent permitted by applicable law, may, after a period of 30 days has
elapsed since such Holder's written request to the Property Trustee to enforce
such rights, institute a legal proceeding directly against the Sponsor to
enforce the Property Trustee's rights under the Debentures without first
instituting any legal proceeding against the Property Trustee or any other
Person; provided further, that, if an Event of Default has occurred and is
continuing and such event is attributed to the failure of the Sponsor to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
then a Holder of Preferred Securities may directly institute a proceeding for
enforcement of payment to such Holder of the principal of or interest on the
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities of such Holder (a "Holder Direct Action") on or
after the respective due date specified in the Debentures. In connection with
such Holder Direct Action, the Sponsor will be subrogated to the rights of such
Holder of Preferred Securities to the extent of any payment made by the Sponsor
to such Holders of Preferred Securities in such Holder Direct Action. Except as
provided in the preceding sentences, the Holders of Preferred Securities will
not be able to exercise directly any other remedy available to the Holders of
the Debentures.

       (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 actually known to a Responsible Officer
of the Property Trustee, transmit by mail, first class postage prepaid, to the
holders of the Securities, as their names and addresses appear upon the
register, notice of such 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 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,
premium 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.

                                       19
<PAGE>

       (h) The Property Trustee shall continue to serve as a Trustee until
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 5.

       (i) The Property Trustee shall act as paying agent in respect of the
Common Securities and, if the Preferred Securities are not in book entry only
form, the Preferred Securities and, subject to Section 3.08(q), 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 ss. 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(q).

       (j) The Property Trustee shall give prompt written notice to the Holders
of the Securities of any notice received by it from Pogo 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.

       (l) 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 Trustees 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 ss. 3807(a) of the
Business Trust Act. 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 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



                                       20
<PAGE>

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.

       (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; provided, however, that 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 of not less than a Majority in
       liquidation amount of the Securities relating to the time, method and
       place of conducting any proceeding for any remedy available to the
       Property Trustee 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
       grounds 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.

                                       21

       (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 an Officers' Certificate which, upon receipt of such request,
       shall be promptly delivered by the Sponsor or the Regular Trustees;

             (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 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 Holder, unless such Holder shall have offered
       to the Property Trustee security and indemnity satisfactory to the
       Property Trustee 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 this
       exercise, as a prudent person would exercise or use under the
       circumstances in the conduct of his or her own affairs; and

             (v) any action taken by the Property Trustee or its agents
       hereunder shall bind 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.

       (d) The Property Trustee, in its individual or any other capacity, may
become the owner or pledgee of Preferred Securities and may otherwise deal with
the Sponsor with the same rights it would have if it were not the Property
Trustee.

                                       22

       (e) All moneys received by the Property Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from other funds except to the extent
required by law. The Property Trustee shall be under no liability for interest
on any moneys received by it hereunder except such as it may agree in writing to
pay thereon.

       (f) Whether or not expressly stated, every provision of this Declaration
pertaining to the Property Trustee shall be subject to this Section 3.12.

execute on behalf of the Trust any such document unless required by the rules
and regulations of the Commission, any Exchange, Nasdaq, the NASD or state
securities or blue sky laws. In connection with all of the foregoing, Pogo and

<PAGE>

effective amendments) to the 1933 Act Registration Statement and the 1934 Act
Registration Statement and to file 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 Pogo 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, may
lawfully do or cause to be done by virtue hereof.

        SECTION 3.14.  Filing of Amendments to Certificate of Trust.

        The Certificate of Trust as filed with the Secretary of State of the
State of Delaware on March 18, 1999 is attached hereto as Exhibit A. On or after

authorized to execute and deliver on behalf of the Trust any documents which the
Regular Trustees have the power and authority to execute or deliver pursuant to

        SECTION 3.16.  Trustees Not Responsible for Recitals or Issuance of
        Securities.

        The recitals contained in this Declaration and the Securities shall be
taken as the statements of the Sponsor, and the Trustees do not assume any
responsibility for their correctness. The Trustees make no representations as to
the value or condition of the property of the Trust or any part thereof. The
Trustees make no representations as to the validity or sufficiency of this
Declaration or the Securities.

        SECTION 3.17.  Duration of the Trust.

        The Trust, absent dissolution pursuant to the provisions of Article 8
hereof, shall continue without dissolution until December 31, 2053.

        SECTION 3.18.  Mergers.

       (a) The Trust may not merge with or into, convert into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, except as described in
Section 3.18(b) and (c) of this Declaration.

       (b) The Trust may, at the request of the Sponsor, with the consent of the
Regular Trustees or, if there are more than two, a majority of the Regular
Trustees and without the consent of the Holders, the Delaware Trustee or the
Property Trustee, merge with or into, convert into, consolidate,

                                       24
<PAGE>

amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets as an entirety or substantially as an entirety to, a trust organized as
such under the laws of any State; provided that:

             (i) such successor entity (the "Successor Entity") either:

                    (A) expressly assumes all of the obligations of the Trust
             under the Securities and this Declaration; or

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

             (ii) the Sponsor expressly appoints a trustee of the Successor
       Entity that possesses the same powers and duties as the Property Trustee
       as the holder of the Debentures;

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

             (iv) if the Preferred Securities (including any Successor
       Securities) are rated by any nationally recognized statistical rating
       organization prior to such transaction, such merger, conversion,
       consolidation, amalgamation, replacement, conveyance, transfer or lease
       does not cause the Preferred Securities (including any Successor
       Securities), or if the Debentures are so rated, the Debentures, to be
       downgraded by any nationally recognized statistical rating organization;

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

             (vi) such Successor Entity has purposes substantially identical to
       those of the Trust;

             (vii) prior to such merger, conversion, consolidation,
       amalgamation, replacement, conveyance, transfer or lease, the Sponsor has
       received an Opinion of Counsel experienced in such matters that:

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

                                       25
<PAGE>

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

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

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

             (ix) there shall have been furnished to the Property Trustee an
       Officers' Certificate and an Opinion of Counsel, each to the effect that
       all conditions precedent in this Declaration to such transaction have
       been satisfied.

       (c) Notwithstanding Section 3.18(b), the Trust shall not, except with the
consent of Holders of 100% in liquidation amount of the Securities, consolidate,
amalgamate, merge with or into, convert into, or be replaced by, or convey,
transfer or lease its properties and assets as an entirety or substantially as
an entirety to, any other Person or permit any other Person to consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger, conversion, replacement, conveyance, transfer or lease
would cause the Trust or the Successor Entity not to be classified as a grantor
trust for United States Federal income tax purposes or would cause the Holders
of the Securities not to be treated as owning an undivided interest in the
Debentures.

        SECTION 3.19.  Property Trustee May File Proofs of Claim.

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

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


                                       26
<PAGE>

advances of the Property Trustee, its agents and counsel) and of the Holders
allowed in such judicial proceeding, and

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

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

        Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or compensation affecting
the Securities or the rights of any Holder thereof to authorize the Property
Trustee to vote in respect of the claim of any Holder in any such proceeding.

                                     SPONSOR

        SECTION 4.01.  Purchase of Common Securities by the Sponsor.

        On the Closing Date, the Sponsor will purchase all of the Common

be issued on such date are issued, such purchase to be in an amount equal to or
greater than 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 a Holder, shall be responsible
for and shall pay for all debts and obligations (other than with respect to the
Securities) and all costs and expenses of the Trust (including, but not limited
to, costs and expenses relating to the organization of the Trust, the issuance
of the Preferred Securities to initial purchasers thereof, the fees and expenses
(including reasonable counsel fees and expenses) of the Trustees (including any
amounts payable under Article 10), the costs and expenses relating to the
operation of the Trust, including, without limitation, costs and expenses of

<PAGE>

        (b) In connection with the purchase of the Debentures by the Trust, the
Sponsor, in its capacity as Sponsor and not as a Holder, shall 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.

       (d) The Sponsor shall be subrogated to all (if any) rights of the Trust
in respect of any amounts paid to any Creditor by the Sponsor under this Section
4.02.

                                    TRUSTEES

        SECTION 5.01.  Number of Trustees; Qualifications.

       (a) 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, removed
or replaced solely by, vote of Holders of Common Securities representing a
Majority in liquidation amount of the Common Securities voting as a class;
provided that in any case:

             (1) the number of Trustees shall be at least five (5) unless the

       Trustee, in which case the number of Trustees shall be at least four (4);

             (2) at least a majority of the Trustees shall at all times be

             (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


                                       28
<PAGE>

       laws of the State of Delaware, then the Property Trustee shall also be

             (4) there shall at all times be a Property Trustee hereunder which
       shall satisfy the requirements of Section 5.01(c).

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

             (i) not be an Affiliate of the Sponsor;

             (ii) be a corporation or national banking association organized and
       doing business under the laws of the United States of America or any
       State or Territory thereof or of the District of Columbia, or a
       corporation, national banking association or Person permitted by the
       Commission to act as an institutional trustee under the Trust Indenture
       Act, authorized under such laws to exercise corporate trust powers,
       having a combined capital and surplus of at least $50,000,000, and
       subject to supervision or examination by Federal, State, Territorial or
       District of Columbia authority. If such corporation or national banking
       association 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

             (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

                                       29
<PAGE>

meaning of ss. 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 ss. 310(b) of the Trust Indenture Act) shall in all respects comply with
the provisions of ss. 310(b) of the Trust Indenture Act. The Preferred
Securities Guarantee and the Indenture shall be deemed to be specifically
described in this Declaration for the purposes of clause (i) of the first
proviso contained in ss. 310(b) of the Trust Indenture Act.

        The initial Trustee which shall serve as the Property Trustee is
Wilmington Trust Company, whose address is as set forth in Section 14.01(b).

       (d) The initial Trustee which shall serve as the Delaware Trustee is
Wilmington Trust Company, whose address is as set forth in Section 14.01(c).

       (e) Any action taken by the Holders of Common Securities pursuant to this
Article 5 shall be taken at a meeting of the 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 the 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 instrument
       executed by the Sponsor; and

             (ii) after the issuance of the Securities by vote of the Holders of
       a Majority in liquidation amount of the Common Securities voting as a
       class.

       (b) (i) The Trustee that acts as the Property Trustee shall not be
removed in accordance with Section 5.02(a) until a Successor Trustee possessing
the qualifications to act as the Property Trustee under Section 5.01(c) (a
"Successor Property Trustee") 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 the Delaware Trustee shall not be
       removed in accordance with Section 5.02(a) until a successor Trustee
       possessing the qualifications to act as the 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.

                                       30
<PAGE>

       (c) A Trustee appointed to office shall hold such 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 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 has been appointed and has
             accepted such appointment by instrument executed by such Successor
             Property Trustee and delivered to the Regular Trustees, 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 Regular Trustees,
       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 of a notice of removal or a Resignation Request,
the Property Trustee or Delaware Trustee being removed of resigning as the case
may be may petition any court of competent jurisdiction for appointment of a
Successor Property Trustee or Successor Delaware Trustee, as the case may be.
Such court may thereupon after prescribing 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.

        SECTION 5.03.  Vacancies among the 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 5.

        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


                                       31
<PAGE>

to dissolve, terminate or annul the Trust. Whenever a vacancy in the number of
Regular Trustees shall occur until such vacancy is filled as provided in this
Article 5, 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 Regular Trustee. Regular meetings of the Regular Trustees may be
held at a time and place fixed by resolution of the Regular Trustees. Notice of
any in-person meeting of the Regular Trustees shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 48 hours before such meeting. Notice of any
telephonic 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 otherwise provided 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 power to delegate from time to time
to such of their number or to officers of the Trust the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the 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.

        SECTION 5.07. Merger, Conversion, Consolidation or Succession to
        Business.

        Any Person into which the Property Trustee or the Delaware Trustee or
any Regular Trustee that is not a natural person, as the case may be, may be
merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which the Property
Trustee or the Delaware Trustee or the Regular Trustees, as the case may be,
shall be a party, or any Person succeeding to all or substantially all of the
corporate trust business of the


                                       32
<PAGE>

Property Trustee or the Delaware Trustee or any Regular Trustee, as the case may
be, shall be the successor of the Property Trustee or the Delaware Trustee or
that Regular Trustee, as the case may be, hereunder, provided that such Person
shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto.

                                  DISTRIBUTIONS

        SECTION 6.01.  Distributions.

        Holders shall receive periodic distributions, redemption payments and
liquidation distributions in accordance with the applicable terms of the
relevant Holder's Securities as set forth in Exhibits B and C hereto
("Distributions"). If and to the extent that Pogo makes a payment of interest
(including Additional Interest and/or Compounded Interest (as defined in the
Indenture)), premium and/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 the extent funds are available for that
purpose, 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. The record dates and payment dates for Distributions shall be the same
as the record dates and payment dates for the Debentures held by the Property
Trustee.


                                    ARTICLE 7
                           ISSUANCE OF THE SECURITIES

        SECTION 7.01.  General Provisions Regarding the Securities.

       (a) The Regular Trustees shall on behalf of the Trust issue 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") hereto, 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") hereto, 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.

                                       33
<PAGE>

        (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 who shall
have signed any of the Certificates shall cease to be 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, although at the
date of the execution and delivery of this Declaration any such person was not a
Regular Trustee. Certificates shall be typewritten, 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 or automated
quotation system on which Securities may be listed or traded, or with any rule
or regulation of the Clearing Agency, 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
(or, if there are more than two Regular Trustees, by any two of 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 Preferred Security Certificate whether in
temporary or definitive form shall be countersigned upon receipt of a written
order of the Trust signed by one Regular Trustee, by the manual signature of an
authorized signatory of the Person acting as registrar and transfer agent for
the Preferred Securities, which shall initially be the Property Trustee.

       (d) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the 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 Pogo the $10
constituting initial trust assets as set forth in the Original Declaration.

        SECTION 7.02.  Conversion Agent.

        The Trust shall maintain an office or agency where Preferred Securities
may be presented for conversion into Common Stock in accordance with the terms
of the Preferred Securities as set forth in Exhibit B hereto ("Conversion
Agent"). The Trust may appoint the Conversion Agent and may appoint one or more
additional Conversion Agents in such other locations as it may determine. The
term "Conversion Agent" includes any additional Conversion Agent. The Trust may
change any Conversion Agent without prior notice to any Holders. If the Trust
fails to appoint or maintain another entity as Conversion Agent, the Property
Trustee will act as such. The Trust or any of its Affiliates may act as
Conversion Agent. The Conversion Agent shall be entitled to the rights and
protections extended to the Property Trustee when acting in such capacity.

        The Property Trustee is hereby initially appointed as the Conversion
Agent for the Preferred Securities.

                            DISSOLUTION OF THE TRUST

        SECTION 8.01.  Dissolution of the Trust.

        The Trust shall dissolve:

             (i) when all of the Securities shall have been called for
       redemption and the amounts necessary for redemption thereof shall have
       been paid to the Holders of the Securities in accordance with the terms
       of the Securities; or

             (ii) when all of the Debentures shall have been distributed to the
       Holders of the 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; or

             (iv) upon a decree of judicial dissolution; or

             (v) upon the distribution of Common Stock to all Securities Holders
       upon conversion of all outstanding Securities.

Upon dissolution and the completion of the winding up of the affairs of the
Trust, the Trust and this Declaration shall terminate when a certificate of
cancellation is filed by the Trustees with the Secretary of State of the State
of Delaware. 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.


                                       35
<PAGE>

        The provisions of Sections 3.12 and 4.02 and Article 10 shall survive
the dissolution and termination of the Trust and this Declaration.


                                    ARTICLE 9
                              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 and in
the terms of the Securities. To the fullest extent permitted by law, any
transfer or purported transfer of any Security not made in accordance with this
Declaration shall be null and void.

       (b) Subject to this Article 9, Preferred Securities shall be freely
transferable.

       (c) The Holder of the Common Securities may not transfer the Common
Securities except (a) in connection with transactions permitted under Section
10.01 of the Indenture, or (b) to the Sponsor or an Affiliate thereof in
compliance with applicable law (including the Securities Act and applicable
state securities and blue sky laws). To the fullest extent permitted by law, any
attempted transfer of the Common Securities other than as set forth in the
immediately preceding sentence shall be null and void.

        SECTION 9.02.  Transfer of Certificates.

        The Regular Trustees 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 Regular Trustees may require) in
respect of any tax or other government charges which may be imposed in relation
to it. Upon surrender for registration of transfer of any Certificate, the
Regular Trustees shall cause one or more new Certificates 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 Regular Trustees 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,

                                       36
<PAGE>

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 Security Certificates, on original issuance 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, except as
       set forth herein in Section 9.07 or in Rule 3a-7 (if the Trust is
       excluded from the definition of an Investment Company solely by reason of
       Rule 3a-7) with respect to the Property Trustee, 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 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, provided,
       that solely for the purposes of determining whether the Holders of the
       requisite amount of Preferred Securities have voted on any matter
       provided for in this Declaration, so long as definitive Preferred
       Security Certificates have not been issued (pursuant to Section 9.07
       hereof), the Trustees may conclusively rely on, and shall be protected in
       relying on, any written instrument (including a proxy) delivered to the
       Trustees by the Clearing Agency setting forth the Preferred Security
       Beneficial Owners' votes or assigning the right to vote on any matter to
       any other Persons either in whole or in part.

        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 Holders of Preferred Securities, 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
in Rule 3a-7 (if the Trust is excluded from the definition of an Investment
Company solely by reason of Rule 3a-7) with respect to the Property Trustee,
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 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 Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and (b) there
shall be delivered to the Regular Trustees such security or indemnity as may be
required by them to keep each of them and the Trust harmless, then in the
absence of notice that such Certificate shall have been acquired by a bona fide
purchaser, the Regular Trustees (or if there are more than two Regular Trustees
by any two of the 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

        SECTION 10.03.  Outside Business.

        The Sponsor and any Trustee (in the case of the Property Trustee,

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,

the Trust even if such opportunity is of a character that, if presented to the
Trust, could be taken by the Trust, and the Sponsor or any Trustee shall have
the right to take for its own account (individually or as a partner or

of, securities or other obligations of the Sponsor or any of its Affiliates.

                                   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.

       (b) If required by applicable law, 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 Section 13(a) or 15(d) of the Exchange Act,
such financial


                                       40
<PAGE>

statements for such Fiscal Year shall be examined and reported on by a firm of
independent certified public accountants selected by the Regular Trustees (which
firm may be the firm used by the Sponsor).

       (c) The Regular Trustees shall cause to be duly prepared and mailed to
each Holder of Securities any annual United States Federal income tax
information statement required by the Code, containing such information with
regard to the Securities held by each Holder as is required by the Code and the
Treasury Regulations. Notwithstanding any right under the Code to deliver any
such statement at a later date, the 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 duly 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.

        SECTION 11.03.  Banking.

        The Trust 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 Regular
Trustees 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 Regular Trustees to assist them in determining the extent of,
and in fulfilling, the Trust's withholding obligations. The Trust shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to Distributions or allocations to any Holder, the amount withheld shall
be deemed to be a Distribution in the amount of the withholding to the Holder.
In the event of any claimed 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 Trust may reduce subsequent Distributions by
the amount of such withholding.

        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;
provided, however, that (i) no amendment or modification to this Declaration
shall be made, and any such purported amendment shall be void and ineffective:
(A) unless the Property Trustee shall have first received: (x) an Officers'
Certificate that such amendment is permitted by, and conforms to, the terms of
this Declaration; and (y) an Opinion of Counsel that such amendment is permitted
by, and conforms to, the terms of this Declaration and that all conditions
precedent, if any, in this Declaration to the execution and delivery of such
amendment have been satisfied; and (B) to the extent the result of such
amendment would be to: (x) cause the Trust to fail to continue to be classified
for purposes of United States Federal income taxation as a grantor trust; (y)
reduce or otherwise adversely affect the rights or powers of the Property
Trustee in contravention of the Trust Indenture Act; or (z) cause the Trust to

Securities which remain outstanding, any amendment which would adversely affect
the rights, privileges or preferences of any Holder of Securities may be
effected only with such additional requirements as may be set forth in the terms
of such Securities; (iii) Section 4.02, Section 9.01(c), this Section 12.01 and
the distribution rate and conversion provisions of the Securities as set forth
in Exhibits B and C hereto shall not be amended without the consent of all of

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)
add to the covenants, restrictions or obligations of the Sponsor, (iv) conform
to any changes in Rule 3a-7 (if the Trust is excluded from the definition of an
Investment Company solely by reason of Rule 3a-7) or any change in
interpretation or application of Rule 3a-7 (if the Trust is excluded from the
definition of an Investment Company solely by reason of Rule 3a-7) by the
Commission, (v) make any other provisions with respect to matters or questions
arising under this Declaration which shall not be inconsistent with the other
provisions of this Declaration, (vi) modify, eliminate or add to any provisions

Investment Company Act, and (vii) pursuant to Section 5.02, evidence the
acceptance of the appointment of a successor Trustee or fill a vacancy created
by an

                                       42

increase in the number of Regular Trustees, in each case which amendment does
not adversely affect in any material respect the rights, preferences or
privileges of the Holders.

        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 the
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 or
automated quotation system on which the Preferred Securities are then listed,
traded or quoted. The Regular Trustees shall call a meeting of the 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 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 the Holders of
Securities:

             (i) Notice of any such meeting shall be given by mail to all the
       Holders of Securities having a right to vote thereat not less than seven
       (7) days nor more than sixty (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 or automated quotation system on which the Preferred Securities
       are then listed, traded or quoted, such vote, consent or approval may be
       given at a meeting of the Holders of Securities. Any action that may be
       taken at a meeting of the Holders of Securities may be taken without a
       meeting and without prior notice if a consent in writing setting forth
       the action so taken is signed by 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 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
       the Security executing it. Except as otherwise provided herein or in the
       terms of the Securities, all matters relating to the

                                       43
<PAGE>

       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 or automated quotation
       system on which the Preferred Securities are then listed, traded or
       quoted, 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 notice, action by consent without a meeting, the establishment of a
       record date, quorum requirements, voting in person or by proxy or any
       other matter with respect to the exercise of any such right to vote.

reason of being a Holder of Securities, has limited liability (in accordance
with the provisions of the Business Trust Act) for the liabilities and
obligations of the Trust. Nothing contained in this Section 14.09 shall be
construed to limit the exercise or enforcement, in accordance with the terms of
this Declaration, the Preferred Guarantee and the Indenture, of the rights and
remedies against the Trust or the Sponsor.

                                                                       EXHIBIT B

                                    TERMS OF
                              PREFERRED SECURITIES

        Pursuant to Section 7.01(b) of the Amended and Restated Declaration of
Trust of Pogo Trust I dated as of June 2, 1999 (as amended from time to time,
the "Declaration"), the designations, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred 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. Three million (3,000,000) Preferred
Securities of the Trust with an aggregate liquidation amount at any time
outstanding with respect to the assets of the Trust of One Hundred Fifty Million
Dollars ($150,000,000), and each with a liquidation amount with respect to the
assets of the Trust of $50 per Preferred Security, are hereby designated as
"6.50% Cumulative Quarterly Income Convertible Preferred Securities, Series A".
The Preferred Security Certificates evidencing the Preferred 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 or to conform to the rules of any stock exchange or automated
quotation system on which the Preferred Securities are then listed, traded or
quoted. In connection with the issuance and sale of the Preferred Securities and
the Common Securities, the Trust will purchase as trust assets Debentures of
Pogo 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 Preferred Security
will be fixed at a rate per annum of 6.50% (the "Coupon Rate") of the stated
liquidation amount of $50 per Preferred Security, such rate being the rate of
interest payable on the Debentures to be held by the Property Trustee.
Distributions in arrears for more than one calendar quarter will accumulate
additional distributions thereon at the Coupon Rate per annum (to the extent
permitted by applicable law), compounded quarterly. The term "Distributions" as
used herein means such periodic cash distributions and any such additional
distributions 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 and to the extent the
Trust has funds on hand legally available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

          (b) Distributions on the Preferred Securities will accumulate from
     June 2, 1999 and will be payable quarterly in arrears, on March 1, June 1,
     September 1 and December 1 of each year, commencing on September 1, 1999,
     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 Pogo shall not be in default in the payment of
     interest on the

<PAGE>

     Debentures, Pogo has the right under the Indenture for the Debentures to
     defer payments of interest on the Debentures by extending the interest
     payment period at any time and from time to time on the Debentures for a
     period not exceeding 20 consecutive quarterly interest periods (each, an
     "Extension Period"), during which Extension Period no interest shall be due
     and payable on the Debentures. As a consequence of such deferral,
     Distributions shall also be deferred. Despite such deferral, Distributions
     will continue to accumulate with additional distributions thereon (to the
     extent permitted by applicable law but not at a rate greater than the rate
     at which interest is then accruing on the Debentures) at the Coupon Rate
     compounded quarterly during any such Extension Period; provided that no
     Extension Period shall extend beyond the stated maturity of the Debentures
     or the date on which Debentures are redeemed. Prior to the termination of
     any such Extension Period, Pogo may further extend such Extension Period;
     provided that such Extension Period together with all such previous and
     further extensions thereof may not exceed 20 consecutive quarterly interest
     periods. Upon the termination of any Extension Period and the payment of
     all amounts then due, Pogo may commence a new Extension Period, subject to
     the above requirements. On the Distribution payment date at the end of an
     Extension Period, payments of accumulated Distributions will be payable to
     Holders of Preferred Securities as they appear on the books and records of
     the Trust (regardless of who the Holders may have been on other dates
     during the Extension Period) on the record date for such Distribution
     payment date.

          (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 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 prior to the
     relevant Distribution date, which record and payment dates correspond to
     the record and interest payment dates on the Debentures. Distributions
     payable on any Preferred Securities that are not punctually paid on any
     Distribution payment date as a result of Pogo's 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 Pogo
     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 section 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

                                      B-2
<PAGE>

     Business Day, in each case with the same force and effect as if made on the
     date such payment was originally payable. Notwithstanding anything herein
     to the contrary, the record dates and payment dates for Distributions shall
     be the same as the record dates and payment dates for the Debentures.

          (d) All Distributions paid with respect to the Preferred Securities
     and the Common Securities will be paid Pro Rata (as defined below) 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.

          (e) In the event of an election by the Holder to convert its Preferred
     Securities through the Conversion Agent into Common Stock pursuant to the
     terms of the Preferred Securities as set forth in this Exhibit B to the
     Declaration, no payment, allowance or adjustment shall be made with respect
     to accumulated and unpaid Distributions on such Preferred Securities, or be
     required to be made; provided, however, that if a Preferred Security is
     surrendered for conversion after the close of business on any regular
     record date for payment of a Distribution and before the opening of
     business on the corresponding Distribution date, then, notwithstanding such
     conversion, the Distribution payable on such Distribution date will be paid
     in cash to the person in whose name the Preferred Security is registered at
     the close of business on such record date.

          (f) 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. (a) In the event of any
voluntary or involuntary dissolution of the Trust, the Holders of the Preferred
Securities and the Common Securities will be entitled to receive Pro Rata solely
out of the assets of the Trust legally available for distribution to Holders of
Preferred Securities and Common Securities after satisfaction of liabilities to
the creditors of the Trust, an amount equal to the aggregate of the stated
liquidation amount of $50 per Preferred Security and Common Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
dissolution and after satisfaction of liabilities to the creditors of the Trust,
Debentures in an aggregate principal amount equal to the aggregate stated
liquidation amount of such Preferred Securities and the Common Securities and
bearing accrued and unpaid interest in an amount equal to the accumulated and
unpaid Distributions on, such Preferred Securities and the Common Securities,
shall be distributed Pro Rata to the Holders of the Preferred Securities and the
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 on hand legally 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.

                                      B-3
<PAGE>

        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.

        (b) The Holder of the Common Securities shall have the right to direct
the Property Trustee in writing at any time to dissolve the Trust and to
distribute Debentures to Holders in exchange for Securities (which direction is
optional and wholly within the discretion of the Holder of the Common
Securities). Upon the receipt of any such written direction, the Property
Trustee shall promptly (i) distribute Debentures in an aggregate principal
amount equal to the aggregate stated liquidation amount of the Preferred
Securities and the Common Securities held by each Holder, which Debentures bear
accrued and unpaid interest in an amount equal to the accumulated and unpaid
Distributions on the Preferred Securities and the Common Securities of such
Holder, in exchange for the Preferred Securities and Common Securities of such
Holder and (ii) dissolve the Trust.

        (c) 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 may be canceled by the Regular Trustees, 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 accumulated and unpaid Distributions on, such Preferred
Securities until such Certificates are presented to Pogo or its agent for
transfer or reissuance.

        (d)If Debentures are distributed to Holders of the Preferred Securities,
Pogo, pursuant to the terms of the Indenture, will use its best efforts to have
the Debentures 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.

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

                (a) Upon the repayment of the Debentures, in whole or in part,
        whether at maturity, upon redemption at any time or from time to time on
        or after June 1, 2002, 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 or redeemed, upon not less than 30
        nor more than 60 days' notice, at the Optional Redemption Price (as such
        term is defined in the Supplemental Indenture). The date of any such
        repayment or redemption 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

                                      B-4

<PAGE>

        Pro Rata and the Preferred Securities will be redeemed as described in
        section 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 or traded, Pogo pursuant to the Indenture will redeem
        Debentures only in whole and, as a result, the Trust may redeem the
        Preferred Securities only in whole.

                (c) (i) If a Special Event shall occur and be continuing, the
        Regular Trustees shall give notice of such Special Event to the Property
        Trustee and shall direct the Conversion Agent to exchange all
        outstanding Preferred Securities for Debentures having a principal
        amount equal to the aggregate liquidation amount of the Preferred
        Securities to be exchanged and with accrued interest (including
        Additional Interest and Compounded Interest, if any) in an amount equal
        to any unpaid Distributions on the Preferred Securities; provided,
        however, that, in the case of a Tax Event, the Sponsor shall have the
        right to (i) direct that less than all, or none, as appropriate, of the
        Preferred Securities be so exchanged if and for so long as the Depositor
        shall have elected to pay any Additional Interest (as defined in the
        Supplemental Indenture) such that the net amounts received by Holders of
        Preferred Securities not so exchanged in respect of Distributions and
        other distributions are not reduced as a result of such Tax Event, and
        shall not have revoked any such election or failed to make such payments
        or (ii) cause the Preferred Securities to be redeemed in the manner set
        forth below. If a Tax Event shall occur or be continuing, the Sponsor
        shall have the right, upon not less than 30 nor more than 60 days'
        notice, to redeem the Debentures, in whole but not in part, for cash at
        the Tax Redemption Price (as defined in the Supplemental Indenture),
        plus accrued and unpaid interest thereon (including Additional Interest
        and Compounded Interest, if any). Promptly following such redemption,
        Preferred 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 Tax Redemption Price, plus accrued and
        unpaid Distributions thereon to the Redemption Date on a pro rata basis.

                        (ii) Notice of any exchange pursuant to this Section
                4(c) (an "Exchange Notice") of the Preferred Securities, which
                Exchange Notice shall be irrevocable, will be given by the
                Property Trustee by first-class mail to the Sponsor and to each
                record Holder of Trust Securities to be exchanged not fewer than
                30 nor more than 60 days prior to the date fixed for exchange
                thereof. For purposes of the calculation of the date of exchange
                and the dates on which notices are given pursuant to this
                paragraph (b), an Exchange Notice shall be deemed to be given on
                the day such notice is first mailed by first-class mail, postage
                prepaid, to each Holder. Each Exchange Notice shall be addressed
                to each Holder of Preferred Securities at the address of such
                Holder appearing in the books and records of the Trust. Each
                Exchange Notice shall state: (A) the exchange date; (B) the
                aggregate liquidation amount and any unpaid Distributions on the
                Trust Securities to be exchanged and the aggregate principal
                amount and any accrued interest on the Debentures to be
                exchanged therefor; (C) that on the exchange date the Preferred
                Securities to be so exchanged shall be exchanged for Debentures
                and that Distributions on the Preferred Securities so exchanged
                will cease to accumulate on and after said date; and (D) the
                identity of the Conversion Agent, if any, and the place or
                places where each Preferred Securities Certificate to be
                exchanged is to be surrendered

                                      B-5

<PAGE>

                in exchange for Debentures. No defect in the Exchange Notice or
                in the mailing thereof with respect to any Preferred Security
                shall affect the validity of the exchange proceedings for any
                other Preferred Security.

                        (iii) In the event that fewer than all the outstanding
                Preferred Securities are to be exchanged, then, on the exchange
                date, (i) if all of the outstanding Preferred Securities are
                represented by Definitive Preferred Securities Certificates, the
                particular Preferred Securities to be exchanged will be selected
                by the Property Trustee from the outstanding Preferred
                Securities not previously called for redemption or exchange on a
                pro rata basis, (ii) if all of the outstanding Preferred
                Securities are represented by Book-Entry Preferred Securities
                Certificates, the Property Trustee shall provide for the
                selection for exchange of a portion of the Global Certificate
                representing the Book-Entry Preferred Securities Certificates on
                a pro rata basis and (iii) if outstanding Preferred Securities
                are represented by both Definitive Preferred Securities
                Certificates and Book-Entry Preferred Securities Certificates,
                the Property Trustee shall select the portion of the Global
                Certificate representing the Book-Entry Preferred Securities
                Certificates and the particular outstanding Preferred Securities
                represented by Definitive Preferred Securities Certificates to
                be exchanged on a pro rata basis. In the case of clause (ii) or
                (iii) above, the particular Book-Entry Preferred Securities
                Certificates to be exchanged shall be selected in accordance
                with the applicable rules and procedures for the Clearing Agency
                in whose name, or whose nominee's name, such Global Certificate
                is then held. Any Preferred Securities Certificate that is to be
                exchanged only in part shall be surrendered with due endorsement
                or by a written instrument of transfer fully executed by the
                Holder thereof (or its attorney duly authorized in writing) and
                the Trust shall prepare and deliver to such Holder, without
                service charge, a new Preferred Securities Certificate or
                Certificates in aggregate stated liquidation amount equal to,
                and in exchange for, the unredeemed portion of the Preferred
                Securities Certificate so surrendered. The Common Securities
                shall be exchanged in a similar manner.

                        (iv) In the event of an exchange pursuant to this
                Section 4(c), on the date fixed for any such exchange, (i) if
                the Preferred Securities are represented by Book-Entry Preferred
                Securities Certificates, the Clearing Agency or its nominee, as
                the record Holder of such Preferred Securities, will exchange
                through the Conversion Agent the Global Certificate representing
                the Preferred Securities to be exchanged for a registered Global
                Certificate or certificates representing the Debentures to be
                delivered upon such exchange, (ii) if the Preferred Securities
                are represented by Definitive Preferred Securities Certificates,
                the certificates representing the Preferred Securities to be so
                exchanged will be deemed to represent Debentures having a
                principal amount equal to the aggregate stated Liquidation
                Preference of such Preferred Securities until such certificates
                are presented to the Conversion Agent for exchange for
                definitive certificates representing Debentures and (iii) all
                rights of the Holders of the Preferred Securities so exchanged
                will cease, except for the right of such Holders to receive
                Debentures. The Common Securities shall be exchanged in a
                similar manner.

                        (v) Each Holder, by becoming a party to the Declaration,
                will be deemed to have agreed to be bound by these exchange
                provisions in regard to the exchange of Preferred Securities for
                Debentures pursuant to the terms described above.

                        (vi) "Tax Event" means that the Sponsor and the Regular
                Trustees shall have received an Opinion of Counsel experienced
                in such matters to the effect that on or after May 26, 1999 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 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 or the publication of any judicial decision or
                regulatory determination), (c) any interpretation or
                pronouncement by any legislative body, court, governmental
                agency or regulatory authority that provides for a position with
                respect to such laws or regulations that differs from its
                previous position or a theretofore commonly accepted position or
                (d) any action taken by any governmental agency or regulatory
                authority, which amendment or change is enacted, promulgated,
                issued or announced or which interpretation or pronouncement is
                issued or announced or which action is taken, in each case on or
                after May 26, 1999, there is more than a remote risk 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 Pogo to the Trust on the
                Debentures is not, or within 90 days of the date thereof will
                not be, deductible by Pogo for United States Federal income tax
                purposes.

                        (vii) "Investment Company Event" means that the Sponsor
                received an Opinion of 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
                Investment Company 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 Investment Company Act
                Law becomes effective on or after May 26, 1999.

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


                (e) [Intentionally omitted.]

                (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

                                      B-7
<PAGE>

        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 section 4(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 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, DTC (or successor Clearing Agency).

                        (iii) Subject to section 9 hereof, if the Trust gives a
                Redemption/Distribution Notice in respect of a redemption of
                Preferred Securities as provided in this section 4 (which notice
                will be irrevocable) then (A) while the Preferred Securities are
                in book-entry only form, with respect to the Preferred
                Securities, by 12:00 noon, New York City time, on the redemption
                date, provided that Pogo 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 successor Clearing Agency) funds sufficient to pay the
                applicable Redemption Price with respect to the Preferred
                Securities and will give DTC (or 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, with respect
                to the Preferred Securities and provided that Pogo 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 accumulate 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

                                      B-8
<PAGE>


                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 payment of the Redemption Price in respect of
                Preferred Securities is improperly withheld or refused and not
                paid either by the Property Trustee or by Pogo pursuant to the
                Preferred Securities Guarantee, Distributions on such Preferred
                Securities will continue to accumulate, 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) Subject to the foregoing and applicable law
                (including, without limitation, United States Federal securities
                laws), Pogo or any of its Affiliates may at any time and from
                time to time purchase outstanding Preferred Securities by
                tender, in the open market or by private agreement.

        5. Conversion Rights. The Holders of Preferred Securities shall have the
right at any time prior to the close of business on May 31, 2029 or, in the case
of Preferred Securities called for redemption, prior to the close of business on
the Business Day prior to the redemption date, at their option, to cause the
Conversion Agent to convert Preferred Securities, on behalf of the converting
Holders, into shares of Common Stock in the manner described herein on and
subject to the following terms and conditions:

                (a) The Preferred Securities will be convertible at the office
        of the Conversion Agent maintained for such purpose in the Borough of
        Manhattan, The City of New York, into fully paid and nonassessable
        shares of Common Stock pursuant to the Holder's direction to the
        Conversion Agent to exchange such Preferred Securities for a portion of
        the Debentures theretofore held by the Trust on the basis of one
        Preferred Security per $50 principal amount of Debentures, and
        immediately convert such amount of Debentures into fully paid and
        nonassessable shares of Common Stock at an initial rate of 2.1053 shares
        of Common Stock per $50 principal amount of Debentures (which is
        equivalent to a conversion price of $23.75 per share of Common Stock,
        subject to certain adjustments set forth in Sections 5.03 and 5.04 of
        the Supplemental Indenture (as so adjusted, "Conversion Price")).

                (b) In order to convert Preferred Securities into Common Stock,
        the Holder shall submit to the Conversion Agent at the office referred
        to above an irrevocable request to convert Preferred Securities on
        behalf of such Holder (the "Conversion Request"), together, if the
        Preferred Securities are in certificated form, with such Preferred
        Security Certificates.

                                       B-9
<PAGE>

        The Conversion Request shall (i) set forth the number of Preferred
        Securities to be converted and the name or names, if other than the
        Holder, in which the shares of Common Stock should be issued and (ii)
        direct the Conversion Agent (a) to exchange such Preferred Securities
        for a portion of the Debentures held by the Trust (at the rate of
        exchange specified in the preceding paragraph) and (b) to immediately
        convert such Debentures on behalf of such Holder into Common Stock,
        subject to certain adjustments set forth in the Supplemental Indenture
        (at the conversion rate specified in the preceding paragraph). The
        Conversion Agent shall notify the Trust of the Holder's election to
        exchange Preferred Securities for a portion of the Debentures held by
        the Trust and the Trust shall, upon receipt of such notice, deliver to
        the Conversion Agent the appropriate principal amount of Debentures for
        exchange in accordance with this Section. The Conversion Agent shall
        thereupon notify the Sponsor of the Holder's election to convert such
        Debentures into shares of Common Stock. If a Preferred Security is
        surrendered for conversion after the close of business on any regular
        record date for payment of a Distribution and before the opening of
        business on the corresponding Distribution payment date, then,
        notwithstanding such conversion, the Distribution payable on such
        Distribution payment date will be paid in cash to the person in whose
        name the Preferred Security is registered at the close of business on
        such record date. Except as provided above, neither the Trust nor the
        Sponsor will make, or be required to make, any payment, allowance or
        adjustment upon any conversion on account of any accumulated and unpaid
        Distributions accumulated on the Preferred Securities surrendered for
        conversion, or on account of any accumulated and unpaid dividends on the
        shares of Common Stock issued upon such conversion, and the delivery of
        Common Stock upon conversion of the Preferred Securities shall be deemed
        to constitute full payment for all accumulated and unpaid Distributions
        on the Preferred Securities. Preferred Securities shall be deemed to
        have been converted immediately prior to the close of business on the
        day on which a Conversion Request relating to such Preferred Securities
        is received by the Trust in accordance with the foregoing provision (the
        "Conversion Date"). The Person or Persons entitled to receive Common
        Stock issuable upon conversion of the Debentures shall be treated for
        all purposes as the record holder or holders of such Common Stock at
        such time. As promptly as practicable on or after the Conversion Date,
        the Sponsor shall issue and deliver at the office of the Conversion
        Agent a certificate or certificates for the number of full shares of
        Common Stock issuable upon such conversion, together with the cash
        payment, if any, in lieu of any fraction of any share to the Person or
        Persons entitled to receive the same calculated in the manner set forth
        in Section 5.02(e) of the Supplemental Indenture, unless otherwise
        directed by the Holder in the Conversion Request, and the Conversion
        Agent shall distribute such certificate or certificates, together with
        the applicable cash payment, if any, to such Person or Persons.

                (c) Each Holder of a Preferred Security by his acceptance
        thereof appoints Wilmington Trust Company as the "Conversion Agent" for
        the purpose of effecting the conversion of Preferred Securities in
        accordance with this Section. In effecting the conversion and
        transactions described in this Section, the Conversion Agent shall be
        acting as agent of the Holders of Preferred Securities directing it to
        effect such conversion transactions. The Conversion Agent is hereby
        authorized (i) to exchange Preferred Securities from time to time for
        Debentures held by the Trust in connection with the conversion of such

                                      B-10
<PAGE>

        Preferred Securities in accordance with this Section and (ii) to convert
        all or a portion of the Debentures into Common Stock and thereupon to
        deliver such shares of Common Stock in accordance with the provisions of
        this Section and to deliver to the Trust a new Debenture or Debentures
        for any resulting unconverted principal amount.

                (d) No fractional shares of Common Stock will be issued as a
        result of conversion, but in lieu thereof, such fractional interest will
        be paid by the Sponsor in cash (based upon the Closing Price (as defined
        in the Supplemental Indenture) of Common Stock on the Conversion Date,
        which in turn will make such payment to the Holder or Holders of
        Preferred Securities so converted, or, if such day is not a day on which
        any securities are traded on the national securities exchange or
        quotation system used to determine the Closing Price, on the next such
        trading day.

                (e) The Sponsor shall at all times reserve and keep available
        out of its authorized and unissued Common Stock, solely for issuance
        upon the conversion of the Debentures, such number of shares of Common
        Stock as shall from time to time be issuable upon the conversion of
        all the Debentures then outstanding. Notwithstanding the foregoing,
        the Sponsor shall be entitled to deliver upon conversion of
        Debentures, shares of Common Stock reacquired and held in the treasury
        of the Sponsor (in lieu of the issuance of authorized and unissued
        shares of Common Stock), so long as any such treasury shares are free
        and clear of all liens, charges, security interests or encumbrances.
        Any shares of Common Stock issued upon conversion of the Debentures
        shall be duly authorized, validly issued and fully paid and
        nonassessable. The Conversion Agent shall deliver the shares of Common
        Stock received upon conversion of the Debentures to the converting
        Holder of Preferred Securities free and clear of all liens, charges,
        security interests and encumbrances, except for United States
        withholding taxes. Whenever the Company issues shares of Common Stock
        upon conversion of Debentures and the Company has in effect at such
        time a share purchase rights agreement under which holders of Common
        Stock are issued rights ("Rights") entitling the holders under certain
        circumstances to purchase an additional share or shares of Common
        Stock or other capital stock of the Company, the Company will issue,
        together with each such share of Common Stock, such number of Rights
        (which number may be a fraction) as shall at that time be issuable
        with a share of Common Stock pursuant to such share purchase rights
        agreement. Each of the Sponsor and the Trust shall prepare and shall
        use its best efforts to obtain and keep in force such governmental or
        regulatory permits or other authorizations as may be required by law,
        and shall comply with all applicable requirements as to registration
        or qualification of Common Stock (and all requirements to list Common
        Stock issuable upon conversion of Debentures that are at the time
        applicable), in order to enable the Sponsor to lawfully issue Common
        Stock to the Trust upon conversion of the Debentures and the Trust to
        lawfully deliver Common Stock to each Holder of Preferred Securities
        upon conversion of the Preferred Securities.

                (f) The Sponsor will pay any and all taxes that may be payable
        in respect of the issue or delivery of shares of Common Stock excluding
        United States withholding taxes on conversion of Debentures and the
        delivery of the shares of Common Stock by the Trust upon conversion of
        the Preferred Securities. The Sponsor shall not, however, be required to
        pay

                                      B-11
<PAGE>

        any tax which may be payable in respect of any transfer involved in the
        issue and delivery of shares of Common Stock in a name other than that
        in which the Preferred Securities so converted were registered, and no
        such issue or delivery shall be made unless and until the Person
        requesting such issue has paid to the Conversion Agent the amount of any
        such tax, or has established to the satisfaction of the Trust that such
        tax has been paid.

                (g) Nothing in the preceding paragraph (f) shall limit the
        requirement of the Trust to withhold taxes pursuant to the terms of the
        Preferred Securities or set forth in this Exhibit B to the Declaration
        or to the Declaration itself or otherwise require the Property Trustee
        or the Trust to pay any amounts on account of such withholdings.

        6. Voting Rights. (a) Except as provided under paragraph 6(b) below and
as otherwise required by law and 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, other than
        as described in Section 12.01(b) of the Declaration or section 3 of
        Exhibit B, or otherwise, or (ii) the dissolution, winding-up or
        termination of the Trust, other than as described in Section 8.01 of the
        Declaration, then the Holders of outstanding Securities will be entitled
        to vote on such amendment or proposal as a single class and such
        amendment or proposal shall not be effective except with the approval of
        the Holders of Securities of at least a Majority in liquidation amount
        of the Securities, voting together as a single class; 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 of Securities will be entitled
        to vote on such amendment or proposal and such amendment or proposal
        shall not be effective except with the approval of at least a Majority
        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, however, 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,
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; and provided, further, that the Property Trustee shall be
under no obligation to take any action in accordance with

                                      B-12
<PAGE>

the directions of the Holders of Securities unless the Property Trustee shall
have received, at the expense of the Sponsor, an Opinion of Counsel experienced
in such matters to the effect that the Trust will not be classified for United
States Federal income tax purposes as other than a grantor trust on account of
such action.

        So long as any Debentures are held by the Property Trustee, the Trustees
shall not (i) direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee of the Indenture (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 of acceleration of the maturity of the principal of the Debentures,
without, in each case, obtaining the prior approval of the Holders of a Majority
in liquidation amount of all outstanding Preferred Securities and Common
Securities. The Trustees shall not revoke any action previously authorized or
approved by a vote of the Holders of the Preferred Securities except by
subsequent vote of such Holders. The Property Trustee shall notify each Holder
of Preferred Securities of any notice of default with respect to the Debentures.

        If an Event of Default has occurred and is continuing, then the Holders
of a Majority in liquidation amount of the Preferred Securities will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Property Trustee or to direct the exercise of any trust
or power conferred upon the Property Trustee under the Declaration, including
the right to direct the Property Trustee to exercise the remedies available to
it as a holder of the Debentures. If the Property Trustee fails to enforce its
rights under the Debentures, a Holder of Preferred Securities, to the extent
permitted by applicable law, may, after a period of 30 days has elapsed since
such Holder's written request to the Property Trustee to enforce such rights,
institute a legal proceeding directly against the Sponsor to enforce the
Property Trustee's rights under the Debentures without first instituting any
legal proceeding against the Property Trustee or any other Person; provided
further, that, if an Event of Default has occurred and is continuing and such
event is attributed to the failure of the Sponsor to pay interest or principal
on the Debentures on the date such interest or principal is otherwise payable
(or in the case of redemption, on the redemption date), then a Holder of
Preferred Securities may directly institute a proceeding for enforcement of
payment to such Holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such Holder (a "Holder Direct Action") on or after the respective
due date specified in the Debentures. In connection with such Holder Direct
Action, the Sponsor will be subrogated to the rights of such Holder of Preferred
Securities to the extent of any payment made by the Sponsor to such Holders of
Preferred Securities in such Holder Direct Action. Except as provided in the
preceding sentences, the Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the Holders of the Debentures.

        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.

                                      B-13
<PAGE>

        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 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 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, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote and (iii) instructions for the delivery of proxies.

        No vote or consent of the Holders of Preferred Securities will be
required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures 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 Pogo or by any Affiliate of
Pogo 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 have no rights to increase or
decrease the number of Trustees or to appoint, remove or replace a Trustee,
which voting rights are vested exclusively in the Holders of the Common
Securities.

        7. 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.

        8. Ranking. The Preferred Securities rank pari passu and payment thereon
will be made Pro Rata with the Common Securities, except that when 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.

        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 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


                                      B-14
<PAGE>

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 Securities Guarantee. Each
Holder of Preferred Securities, by the acceptance thereof, agrees to the
provisions of (i) the Preferred Securities Guarantee, including the
subordination provisions therein, 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 or similar 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 of Preferred Securities without charge on written request to the
Trust at its principal place of business.

                            FORM OF PREFERRED SECURITY CERTIFICATE

        [IF THE PREFERRED SECURITY IS TO BE A GLOBAL CERTIFICATE INSERT This
Preferred Security is a Global Certificate within the meaning of the Declaration
hereinafter referred to and is registered in the name of The Depository Trust
Company ("DTC") or a nominee of DTC. This Preferred Security is exchangeable for
Preferred Securities registered in the name of a person other than DTC or its

transfer of this Preferred Security (other than a transfer of this Preferred
Security as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or
another nominee of DTC) may be registered except in limited circumstances.

        Unless this Preferred Security is presented by an authorized
representative of The Depository Trust Company (55 Water Street, New York, New

  6.50% Cumulative Quarterly Income Convertible Preferred Securities, Series A

the Trust and designated the 6.50% Cumulative Quarterly Income Convertible
Preferred Securities, Series A (liquidation amount $50 per Preferred Security)
(the "Preferred Securities"). The Preferred Securities are transferable on the
books and records of the Trust, in person or by a duly authorized attorney, upon
surrender of this Certificate duly endorsed and in proper form for transfer. The
designations, rights, privileges, restrictions, preferences and other terms and
provisions of the Preferred Securities are set forth in, and this Certificate
and the Preferred Securities represented hereby are issued and shall in all
respects be subject to the terms and provisions of, the Amended and Restated
Declaration of Trust of the Trust dated as of June 2, 1999, as the same may be
amended from time to time (the "Declaration") including the designation of the
terms of Preferred Securities as set forth in Exhibit B thereto. The Preferred
Securities and the Common Securities issued by the Trust pursuant to the
Declaration represent undivided beneficial interests in the assets of the Trust,
including the Debentures (as defined in the Declaration) issued by Pogo
Producing Company, a Delaware corporation ("Pogo"), to the Trust pursuant to the
Indenture referred to in the Declaration. The Holder is entitled to the benefits
of the Guarantee Agreement of Pogo dated as of June 2, 1999 (the "Guarantee") to
the extent provided therein. The Trust will furnish a copy of the Declaration,
the Guarantee and the Indenture to the Holder without charge upon written

to have (i) agreed to the terms of the Indenture and the Debentures, including
that the Debentures are subordinate and junior in right of payment to all Senior

agreed to the terms of the Guarantee, including that the Guarantee is
subordinate and junior in right of payment to all other liabilities of Pogo,
including the Debentures, except those made pari passu or subordinate by their
terms, and senior to all capital stock (other than the most senior preferred
stock issued, from time to time, if any, by Pogo, which preferred stock will
rank pari passu with the Guarantee) now or hereafter issued by Pogo and to any
guarantee now or hereafter entered into by Pogo in respect of any of its capital
stock (other than the most senior preferred stock issued, from time to time, if
any, by Pogo).

and is entitled to the benefits thereunder.

                          [FORM OF REVERSE OF SECURITY]

        Distributions payable on each Preferred Security will be fixed at a rate
per annum of 6.50% (the "Coupon Rate") of the stated liquidation amount of $50
per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one quarter will accumulate additional distributions thereon at the Coupon
Rate per annum (to the extent permitted by applicable law), compounded
quarterly. The term "Distributions" as used herein means such periodic cash
distributions and any such additional distributions payable unless otherwise
stated. A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Property Trustee and to the extent the
Trust has funds on hand legally available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

        Distributions on the Preferred Securities will accumulate from June 2,
1999, and will be payable quarterly in arrears, on March 1, June 1, September 1
and December 1 of each year, commencing on September 1, 1999, 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 Pogo shall not be in default in the payment of
interest on the Debentures, Pogo has the right under the Indenture for the
Debentures to defer payments of interest on the Debentures by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 20 consecutive quarterly interest periods (each an
"Extension Period"), during which Extension Period no interest shall be due and
payable on the Debentures. As a consequence of such deferral, Distributions
shall also be deferred. Despite such deferral, Distributions will continue to
accumulate with additional distributions thereon (to the extent permitted by
applicable law but not at a rate greater than the rate at which interest is then
accruing on the Debentures) at the Coupon Rate compounded quarterly during any
such Extension Period; provided that no Extension Period shall extend beyond the
stated maturity of the Debentures. Prior to the termination of any such
Extension Period, Pogo may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarterly interest periods. Upon the
termination of any Extension Period and the payment of all amounts then due,
Pogo may commence a new Extension Period, subject to the above requirements. On
the Distribution payment date at the end of the Extension Period, payments of
accumulated Distributions will be payable to Holders of Preferred Securities as
they appear on the books and records of the Trust (regardless of who the Holders
may have been on other dates during the Extension Period) on the record date for
such Distribution payment date.

        The Preferred Securities shall be redeemable or subject to mandatory
exchange upon the occurrence of a Special Event as provided in the Declaration.

        The Preferred Securities shall be convertible into shares of Common
Stock (as defined in the Declaration), through (i) the exchange of Preferred
Securities for a portion of the Debentures and (ii) the immediate conversion of
such Debentures into Common Stock, in the manner and according to


                                      B-19

the terms set forth in the Declaration upon submission of a Conversion Request
(as defined in the Declaration) to the Conversion Agent (as defined in the
Declaration). A form of Conversion Request is provided at the end of this
Preferred Securities Certificate.

        To: Wilmington Trust Company, as Property Trustee of Pogo Trust I

        The undersigned owner of these Preferred Securities hereby irrevocably
exercises the option to convert these Preferred Securities, or the portion below
designated, into Common Stock (as that term is defined in the Amended and
Restated Declaration of Trust, dated as of June 2, 1999 (as amended from time to
time, the "Declaration"), by John O. McCoy, Jr., John W. Elsenshans and Gerald
A. Morton as Regular Trustees, Wilmington Trust Company, as the Delaware
Trustee, Wilmington Trust Company, as the Property Trustee, Pogo Producing
Company, as Sponsor, and by the Holders, from time to time, of undivided
beneficial interests in the assets of the Trust to be issued pursuant to the
Declaration) in accordance with and subject to the terms and conditions of the
Declaration. Pursuant to the aforementioned exercise of the option to convert
these Preferred Securities, the undersigned hereby directs the Conversion Agent
(as that term is defined in the Declaration) to (i) exchange such Preferred
Securities for a portion of the Debentures (as that term is defined in the
Declaration) held by Pogo Trust I (at the rate of exchange specified in the
terms of the Preferred Securities set forth as Exhibit B to the Declaration) and
(ii) immediately convert such Debentures on behalf of the undersigned into
Common Stock (at the conversion rate specified in the terms of the Preferred
Securities set forth as Exhibit B to the Declaration, subject to certain
adjustments set forth in the Supplemental Indenture (as that term is defined in
the Declaration)).

        The undersigned does also hereby direct the Conversion Agent that the
shares of Common Stock issuable and deliverable upon conversion, together with
any check in payment for fractional shares, be issued in the name of and
delivered to the undersigned, unless a different name has been indicated in the
assignment below. If shares of Common Stock are to be issued in the name of a
person other than the undersigned, the undersigned will pay all transfer taxes
payable with respect thereto.

                                COMMON SECURITIES

        Pursuant to Section 7.01(b) of the Amended and Restated Declaration of
Trust of Pogo Trust I dated as of June 2, 1999 (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. Ninety-two thousand eight hundred (92,800)
Common Securities of the Trust with an aggregate liquidation amount at any time
outstanding with respect to the assets of the Trust of Four Million Six Hundred
Forty Thousand Dollars ($4,640,000), and each with a liquidation amount with
respect to the assets of the Trust of $50 per Common Security, are hereby
designated as "6.50% Cumulative Quarterly Income Convertible Common Securities,
Series A". 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. In connection with the issuance and sale of the
Preferred Securities and the Common Securities, the Trust will purchase as trust
assets Debentures of Pogo 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 6.50% (the "Coupon Rate") of the stated
liquidation amount of $50 per Common Security, such rate being the rate of
interest payable on the Debentures to be held by the Property Trustee.
Distributions in arrears for more than one calendar quarter will accumulate
additional distributions thereon at the Coupon Rate per annum (to the extent
permitted by applicable law), compounded quarterly. The term "Distributions" as
used herein means such periodic cash distributions and any such additional
distributions 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 and to the extent the
Trust has funds on hand legally available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

                (b) Distributions on the Common Securities will accumulate from
        June 2, 1999 and will be payable quarterly in arrears, on March 1, June
        1, September 1 and December 1 of each year commencing on September 1,
        1999, 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

                                      C-1
<PAGE>

        Property Trustee. So long as Pogo shall not be in default in the payment
        of interest on the Debentures, Pogo has the right under the Indenture
        for the Debentures to defer payments of interest on the Debentures by
        extending the interest payment period at any time and from time to time
        on the Debentures for a period not exceeding 20 consecutive quarterly
        interest periods (each, an "Extension Period"), during which Extension
        Period no interest shall be due and payable on the Debentures. As a
        consequence of such deferral, Distributions shall also be deferred.
        Despite such deferral, Distributions will continue to accumulate with
        additional distributions thereon (to the extent permitted by applicable
        law but not at a rate greater than the rate at which interest is then
        accruing on the Debentures) at the Coupon Rate compounded quarterly
        during any such Extension Period; provided that no Extension Period
        shall extend beyond the stated maturity of the Debentures or the date on
        which Debentures are redeemed. Prior to the termination of any such
        Extension Period, Pogo may further extend such Extension Period;
        provided that such Extension Period together with all such previous and
        further extensions thereof may not exceed 20 consecutive quarterly
        interest periods. Upon the termination of any Extension Period and the
        payment of all amounts then due, Pogo may commence a new Extension
        Period, subject to the above requirements. On the Distribution payment
        date at the end of the Extension Period, payments of accumulated
        Distributions will be payable to Holders of Common Securities as they
        appear on the books and records of the Trust (regardless of who the
        Holders may have been on other dates during the Extension Period) on the
        record date for such Distribution payment date.

                (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 Holders thereof as they appear on the
        books and records of the Trust on the relevant record dates. While the
        Preferred Securities remain in book-entry only form, the relevant record
        dates for the Common Securities 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 for the Common
        Securities will be the fifteenth (15th) day of the month prior to the
        relevant Distribution date, which record and payment dates correspond to
        the record and interest payment dates on the Debentures. Distributions
        payable on any Common Securities that are not punctually paid on any
        Distribution payment date as a result of Pogo's 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
        Pogo 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 section 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

                                      C-2
<PAGE>

        made on the immediately preceding Business Day, in each case with the
        same force and effect as if made on the date such payment was originally
        payable. Notwithstanding anything herein to the contrary, the record
        dates and payment dates for Distributions shall be the same as the
        record dates and payment dates for the Debentures.

                (d) All Distributions paid with respect to the Common Securities
        and the Preferred Securities will be paid Pro Rata (as defined below) 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.

                (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. (a) In the event of any
voluntary or involuntary dissolution of the Trust, the Holders of the Preferred
Securities and the Common Securities will be entitled to receive Pro Rata solely
out of the assets of the Trust legally available for distribution to Holders of
Preferred Securities and Common Securities after satisfaction of liabilities to
the creditors of the Trust, an amount equal to the aggregate of the stated
liquidation amount of $50 per Preferred Security and Common Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
dissolution, and after satisfaction of liabilities to the creditors of the
Trust, Debentures in an aggregate principal amount equal to the aggregate stated
liquidation amount of such Preferred Securities and the Common Securities and
bearing accrued and unpaid interest in an amount equal to the accumulated and
unpaid Distributions on, such Preferred Securities and the Common Securities,
shall be distributed Pro Rata to the Holders of the Preferred Securities and the
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 on hand legally 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.

        (b) The Holder of the Common Securities shall have the right to direct
the Property Trustee in writing at any time to dissolve the Trust and to
distribute Debentures to Holders in exchange for Securities (which direction is
optional and wholly within the discretion of the Holder of the Common
Securities). Upon the receipt of any such written direction, the Property
Trustee shall promptly (i) distribute Debentures in an aggregate principal
amount equal to the aggregate stated liquidation amount of the Preferred
Securities and the Common Securities held by each Holder, which Debentures bear
accrued and unpaid interest in an amount equal to the accumulated and unpaid
Distributions on the Preferred Securities and the Common Securities of such
Holder, in


                                      C-3
<PAGE>

exchange for the Preferred Securities and Common Securities of such Holder and
(ii) dissolve the Trust.

        (c) 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 may be canceled by the Regular Trustees and (ii) 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
accumulated and unpaid Distributions on, such Common Securities until such
Certificates are presented to Pogo or its agent for transfer or reissuance.

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

                (a) Upon the repayment of the Debentures, in whole or in part,
        whether at maturity, upon redemption at any time or from time to time on
        or after June 1, 2002, 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 or redeemed, upon not less than 30
        nor more than 60 days' notice, at the Optional Redemption Price (as such
        term is defined in the Supplemental Indenture). The date of any such
        repayment or redemption 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 the Common
        Securities will be redeemed as described in section 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 or traded, Pogo pursuant
        to the Indenture will redeem Debentures only in whole and, as a result,
        the Trust may redeem the Common Securities only in whole.

                (c) (i) If a Special Event shall occur and be continuing, the
        Regular Trustees shall give notice of such Special Event to the Property
        Trustee and shall direct the Conversion Agent to exchange all
        outstanding Common Securities for Debentures having a principal amount
        equal to the aggregate liquidation amount of the Common Securities to be
        exchanged and with accrued interest (including Additional Interest and
        Compounded Interest, if any) in an amount equal to any unpaid
        Distributions on the Common Securities; provided, however, that, in the
        case of a Tax Event, the Sponsor shall have the right to (i) direct that
        less than all, or none, as appropriate, of the Common Securities be so
        exchanged if and for so long as the Depositor shall have elected to pay
        any Additional Interest (as defined in the Supplemental Indenture) such
        that the net amounts received by Holders of Common Securities not so
        exchanged in respect of Distributions and other distributions are not
        reduced as a result of such Tax Event, and shall not have revoked any
        such election or failed to make such payments or (ii) cause the Common
        Securities to be redeemed in the manner

                                      C-4
<PAGE>

        set forth below. If a Tax Event shall occur or be continuing, the
        Sponsor shall have the right, upon not less than 30 nor more than 60
        days' notice, to redeem the Debentures, in whole but not in part, for
        cash at the Tax Redemption Price (as defined in the Supplemental
        Indenture), plus accrued and unpaid interest thereon (including
        Additional Interest and Compounded Interest, if any). Promptly following
        such redemption, 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 Tax Redemption Price, plus accrued
        and unpaid Distributions thereon to the Redemption Date on a pro rata
        basis.

                        (ii) Notice of any exchange pursuant to this Section
                4(c) (an "Exchange Notice") of the Common Securities, which
                Exchange Notice shall be irrevocable, will be given by the
                Property Trustee by first-class mail to the Sponsor and to each
                record Holder of Trust Securities to be exchanged not fewer than
                30 nor more than 60 days prior to the date fixed for exchange
                thereof. For purposes of the calculation of the date of exchange
                and the dates on which notices are given pursuant to this
                paragraph (b), an Exchange Notice shall be deemed to be given on
                the day such notice is first mailed by first-class mail, postage
                prepaid, to each Holder. Each Exchange Notice shall be addressed
                to each Holder of Common Securities at the address of such
                Holder appearing in the books and records of the Trust. Each
                Exchange Notice shall state: (A) the exchange date; (B) the
                aggregate liquidation amount and any unpaid Distributions on the
                Trust Securities to be exchanged and the aggregate principal
                amount and any accrued interest on the Debentures to be
                exchanged therefor; (C) that on the exchange date the Common
                Securities to be so exchanged shall be exchanged for Debentures
                and that Distributions on the Common Securities so exchanged
                will cease to accumulate on and after said date; and (D) the
                identity of the Conversion Agent, if any, and the place or
                places where each Common Securities Certificate to be exchanged
                is to be surrendered in exchange for Debentures. No defect in
                the Exchange Notice or in the mailing thereof with respect to
                any Common Security shall affect the validity of the exchange
                proceedings for any other Common Security.

                        (iii) In the event that fewer than all the outstanding
                Common Securities are to be exchanged, then, on the exchange
                date, the particular Common Securities to be exchanged will be
                selected by the Property Trustee from the outstanding Common
                Securities not previously called for redemption or exchange on a
                pro rata basis. Any Common Securities Certificate that is to be
                exchanged only in part shall be surrendered with due endorsement
                or by a written instrument of transfer fully executed by the
                Holder thereof (or its attorney duly authorized in writing) and
                the Trust shall prepare and deliver to such Holder, without
                service charge, a new Common Securities Certificate or
                Certificates in aggregate stated liquidation amount equal to,
                and in exchange for, the unredeemed portion of the Common
                Securities Certificate so surrendered. The Common Securities
                shall be exchanged in a similar manner.

                        (iv) Each Holder, by becoming a party to the
                Declaration, will be deemed to have agreed to be bound by these
                exchange provisions in regard to the exchange of Common
                Securities for Debentures pursuant to the terms described above.

                                      C-5
<PAGE>

                        (v) "Tax Event" means that the Sponsor and the Regular
                Trustees shall have received an Opinion of Counsel experienced
                in such matters to the effect that on or after May 26, 1999, 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 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 or 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 its previous position or a
                theretofore commonly accepted position or (d) any action taken
                by any governmental agency or regulatory authority, which
                amendment or change is enacted, promulgated, issued or announced
                or which interpretation or pronouncement by any legislative
                body, court, governmental agency or regulatory authority is
                issued or announced or which action is taken, in each case on or
                after May 26, 1999, there is more than a remote risk 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 Pogo to the Trust on the
                Debentures is not, or within 90 days of the date thereof will
                not be, deductible by Pogo for United States Federal income tax
                purposes.

                        (vi) "Investment Company Event" means that the Sponsor
                and the Regular Trustees shall have received an Opinion of
                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 Investment Company
                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 Investment Company Act Law becomes effective on
                or after May 26, 1999.

                (d) The Trust may not redeem fewer than all the outstanding
        Common Securities unless all accumulated and unpaid Distributions have
        been paid on all Common Securities for all quarterly 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
        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 section 4(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

                                      C-6
<PAGE>

        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 section 4 (which notice will be irrevocable),
                then immediately prior to the close of business on the
                redemption date, provided that Pogo 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 accumulate 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 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 accumulate, 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 Holders of the
                Common Securities.

        5.   Conversion Rights.

        The Holders of Common Securities shall have the right at any time prior
to the close of business on May 31, 2029 or, in the case of Common Securities
called for redemption, prior to the close of business on the Business Day prior
to the redemption date, at their option, to cause the Conversion Agent to
convert Common Securities, on behalf of the converting Holders, into shares of
Common Stock in the manner described herein on and subject to the following
terms and conditions:

                                      C-7
<PAGE>

                (a) The Common Securities will be convertible at the office of
        the Conversion Agent into fully paid and nonassessable shares of Common
        Stock pursuant to the Holder's direction to the Conversion Agent to
        exchange such Common Securities for a portion of the Debentures
        theretofore held by the Trust on the basis of one Common Security per
        $50 principal amount of Debentures, and immediately convert such amount
        of Debentures into fully paid and nonassessable shares of Common Stock
        at an initial rate of 2.1053 shares of Common Stock per $50 principal
        amount of Debentures (which is equivalent to a conversion price of
        $23.75 per share of Common Stock, subject to certain adjustments set
        forth in Sections 5.03 and 5.04 of the Supplemental Indenture (as so
        adjusted, "Conversion Price")).

                (b) In order to convert Common Securities into Common Stock, the
        Holder shall submit to the Conversion Agent at the office referred to
        above an irrevocable request to convert Common Securities on behalf of
        such Holder (the "Conversion Request"), together, if the Common
        Securities are in certificated form, with such Common Security
        Certificates. The Conversion Request shall (i) set forth the number of
        Common Securities to be converted and the name or names, if other than
        the Holder, in which the shares of Common Stock should be issued and
        (ii) direct the Conversion Agent (a) to exchange such Common Securities
        for a portion of the Debentures held by the Trust (at the rate of
        exchange specified in the preceding paragraph) and (b) to immediately
        convert such Debentures on behalf of such Holder, into Common Stock,
        subject to certain adjustments set forth in the Supplemental Indenture
        (at the conversion rate specified in the preceding paragraph). The
        Conversion Agent shall notify the Trust of the Holder's election to
        exchange Common Securities for a portion of the Debentures held by the
        Trust, and the Trust shall, upon receipt of such notice, deliver to the
        Conversion Agent the appropriate principal amount of Debentures for
        exchange in accordance with this Section. The Conversion Agent shall
        thereupon notify the Sponsor of the Holder's election to convert such
        Debentures into shares of Common Stock. If a Common Security is
        surrendered for conversion after the close of business on any regular
        record date for payment of a Distribution and before the opening of
        business on the corresponding Distribution payment date, then,
        notwithstanding such conversion, the Distribution payable on such
        Distribution payment date will be paid in cash to the person in whose
        name the Common Security is registered at the close of business on such
        record date. Except as provided above, neither the Trust nor the Sponsor
        will make, or be required to make, any payment, allowance or adjustment
        upon any conversion on account of any accumulated and unpaid
        Distributions accumulated on the Common Securities surrendered for
        conversion, or on account of any accumulated and unpaid dividends on the
        shares of Common Stock issued upon such conversion, and the delivery of
        Common Stock upon conversion of the Common Securities shall be deemed to
        constitute full payment for all accumulated and unpaid Distributions on
        the Common Securities. Common Securities shall be deemed to have been
        converted immediately prior to the close of business on the day on which
        a Conversion Request relating to such Common Securities is received by
        the Trust in accordance with the foregoing provision (the "Conversion
        Date"). The Person or Persons entitled to receive Common Stock issuable
        upon conversion of the Debentures shall be treated for all purposes as
        the record holder or holders of such Common Stock at such time. As
        promptly as practicable on or after the Conversion Date, the Sponsor
        shall issue and deliver at the office of the Conversion Agent a
        certificate or certificates for the number of full shares of Common
        Stock issuable upon such conversion, together with the cash payment, if

                                      C-8
<PAGE>

        any, in lieu of any fraction of any share to the Person or Persons
        entitled to receive the same calculated in the manner set forth in
        Section 5.02(e) of the Supplemental Indenture, unless otherwise directed
        by the Holder in the Conversion Request, and the Conversion Agent shall
        distribute such certificate or certificates, together with the
        applicable cash payment, if any, to such Person or Persons.

                (c) Each Holder of a Common Security by his acceptance thereof
        appoints Wilmington Trust Company as the "Conversion Agent" for the
        purpose of effecting the conversion of Common Securities in accordance
        with this Section. In effecting the conversion and transactions
        described in this Section, the Conversion Agent shall be acting as agent
        of the Holders of Common Securities directing it to effect such
        conversion transactions. The Conversion Agent is hereby authorized (i)
        to exchange Common Securities from time to time for Debentures held by
        the Trust in connection with the conversion of such Common Securities in
        accordance with this Section and (ii) to convert all or a portion of the
        Debentures into Common Stock and thereupon to deliver such shares of
        Common Stock in accordance with the provisions of this Section and to
        deliver to the Trust a new Debenture or Debentures for any resulting
        unconverted principal amount.

                (d) No fractional shares of Common Stock will be issued as a
        result of conversion, but in lieu thereof, such fractional interest will
        be paid by the Sponsor in cash (based upon the Closing Price (as defined
        in the Supplemental Indenture) of Common Stock on the Conversion Date,
        which in turn will make such payment to the Holder or Holders of Common
        Securities so converted, or, if such day is not a day on which any
        securities are traded on the national securities exchange or quotation
        system used to determine the Closing Price, on the next such trading
        day.

                (e) The Sponsor shall at all times reserve and keep available
        out of its authorized and unissued Common Stock, solely for issuance
        upon the conversion of the Debentures, such number of shares of Common
        Stock as shall from time to time be issuable upon the conversion of all
        the Debentures then outstanding. Notwithstanding the foregoing, the
        Sponsor shall be entitled to deliver upon conversion of Debentures,
        shares of Common Stock reacquired and held in the treasury of the
        Sponsor (in lieu of the issuance of authorized and unissued shares of
        Common Stock), so long as any such treasury shares are free and clear of
        all liens, charges, security interests or encumbrances. Any shares of
        Common Stock issued upon conversion of the Debentures shall be duly
        authorized, validly issued and fully paid and nonassessable. The
        Conversion Agent shall deliver the shares of Common Stock received upon
        conversion of the Debentures to the converting Holder of Common
        Securities free and clear of all liens, charges, security interests and
        encumbrances, except for United States withholding taxes. Whenever the
        Company issues shares of Common Stock upon conversion of Debentures and
        the Company has in effect at such time a share purchase rights agreement
        under which holders of Common Stock are issued rights ("Rights")
        entitling the holders under certain circumstances to purchase an
        additional share or shares of Common Stock or other capital stock of the
        Company, the Company will issue, together with each such share of Common
        Stock, such number of Rights (which number may be a fraction) as shall
        at that time be issuable with a share of Common Stock pursuant to such
        share purchase rights agreement. Each of the Sponsor and the Trust shall
        prepare and shall use its best

                                       C-9

<PAGE>

        efforts to obtain and keep in force such governmental or regulatory
        permits or other authorizations as may be required by law, and shall
        comply with all applicable requirements as to registration or
        qualification of Common Stock (and all requirements to list Common Stock
        issuable upon conversion of Debentures that are at the time applicable),
        in order to enable the Sponsor to lawfully issue Common Stock to the
        Trust upon conversion of the Debentures and the Trust to lawfully
        deliver Common Stock to each Holder of Common Securities upon conversion
        of the Securities.

                (f) The Sponsor will pay any and all taxes that may be payable
        in respect of the issue or delivery of shares of Common Stock excluding
        United States withholding taxes on conversion of Debentures and the
        delivery of the shares of Common Stock by the Trust upon conversion of
        the Common Securities. The Sponsor shall not, however, be required to
        pay any tax which may be payable in respect of any transfer involved in
        the issue and delivery of shares of Common Stock in a name other than
        that in which the Common Securities so converted were registered, and no
        such issue or delivery shall be made unless and until the Person
        requesting such issue has paid to the Conversion Agent the amount of any
        such tax, or has established to the satisfaction of the Trust that such
        tax has been paid.

                (g) Nothing in the preceding section 5(f) shall limit the
        requirement of the Trust to withhold taxes pursuant to the terms of the
        Common Securities or set forth in this Exhibit C to the Declaration or
        to the Declaration itself or otherwise require the Property Trustee or
        the Trust to pay any amounts on account of such withholdings.

        6. Voting Rights. (a) Except as provided under section 6(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 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, other than as described in
Section 12.01(b) of the Declaration, or otherwise, or (ii) the dissolution,
winding-up or termination of the Trust, other than as described in Section 8.01
of the Declaration or section 3 of this Exhibit C, then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a single class and such amendment or proposal shall not be effective except with
the approval of the Holders of Securities of at least a Majority in liquidation
amount of the Securities, voting together as a single class; 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 of Securities will be entitled to vote on such amendment
or proposal and such amendment or proposal shall not be effective except with
the approval of at least a Majority in liquidation amount of such class of
Securities, (B) the rights of Holders of Common Securities under Section 5.02 of
the Declaration to increase or decrease the number of, and to appoint, replace
or

                                      C-10
<PAGE>

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, however, 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,
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; 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 Counsel experienced in such matters to the
effect that the Trust will not be classified for United States Federal income
tax purposes as other than a grantor trust on account of such action.

        So long as any Debentures are held by the Property Trustee, the Trustees
shall not (i) direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee of the Indenture (the "Debenture Trustee"),
or exercising any trust or power conferred on such 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 of acceleration of the maturity of the principal of the Debentures,
without, in each case, obtaining the prior approval of the Holders of a Majority
in liquidation amount of all outstanding Common Securities and Preferred
Securities. The Trustees shall not revoke any action previously authorized or
approved by a vote of the Holders of the Common Securities except by subsequent
vote of such Holders. The Property Trustee shall notify each Holder of Common
Securities of any notice of default with respect to the Debentures.

        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 such waiver shall also constitute the waiver of
such

                                      C-11
<PAGE>

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

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

        7. 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 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.

        8. Ranking. The Common Securities rank pari passu and payment thereon
will be made Pro Rata with the Preferred Securities, except that when 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.

        9. Transfer, Exchange, Method of 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

                                      C-12
<PAGE>

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 Indenture and the Debentures,
including the subordination provisions of the Indenture.

       11. No Preemptive Rights. The Holders of Common Securities shall have no
preemptive or similar 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 of Common Securities without charge on written request to the Trust
at its principal place of business.

                             TITLE: REGULAR TRUSTEE


                          BY_________________________, AS REGULAR TRUSTEE
                             NAME: GERALD A. MORTON
                             TITLE: REGULAR TRUSTEE

<PAGE>

                         [FORM OF REVERSE OF SECURITY]

        Distributions payable on each Common Security will be fixed at a rate
per annum of 6.50% (the "Coupon Rate") of the stated liquidation amount of $50
per Common Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one calendar quarter will accumulate additional distributions thereon at
the Coupon Rate per annum (to the extent permitted by applicable law) compounded
quarterly. The term "Distributions" as used herein means such periodic cash
distributions and any such additional distributions payable unless otherwise
stated. A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Property Trustee and to the extent the
Trust has funds on hand legally available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

        Distributions on the Common Securities will accumulate from June 2, 1999
and will be payable quarterly in arrears, on March 1, June 1, September 1 and
December 1 of each year, commencing on September 1, 1999, 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 Pogo shall not be in default in the payment of
interest on the Debentures, Pogo has the right under the Indenture for the
Debentures to defer payments of interest on the Debentures by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 20 consecutive quarterly interest periods (each an
"Extension Period"), during which Extension Period no interest shall be due and
payable on the Debentures. As a consequence of such deferral, Distributions
shall also be deferred. Despite such deferral, Distributions will continue to
accumulate with additional distributions thereon (to the extent permitted by
applicable law but not at a rate greater than the rate at which interest is then
accruing on the Debentures) at the Coupon Rate compounded quarterly during any
such Extension Period; provided that no Extension Period shall extend beyond the
stated maturity of the Debentures. Prior to the termination of any such
Extension Period, Pogo may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarterly interest periods. Upon the
termination of any Extension Period and the payment of all amounts then due,
Pogo may commence a new Extension Period, subject to the above requirements. On
the Distribution payment date at the end of the Extension Period, payments of
accumulated Distributions will be payable to Holders of Common Securities as
they appear on the books and records of the Trust (regardless of who the Holders
may have been on other dates during the Extension Period) on the record date for
such Distribution payment date.

        The Common Securities shall be redeemable or subject to mandatory
exchange upon the occurrence of a Special Event as provided in the Declaration.

        The Common Securities shall be convertible into shares of Common Stock
(as defined in the Declaration), through (i) the exchange of Common Securities
for a portion of the Debentures and (ii) the immediate conversion of such
Debentures into Common Stock, in the manner and according to the terms set
forth in the Declaration upon submission of a Conversion Request (as defined
in the

                                      C-16

Declaration) to the Conversion Agent (as defined in the Declaration). A form of
Conversion Request is provided at the end of this Preferred Securities
Certificate.
