       Consequences", and under the caption "Underwriting," insofar as they

       insolvency, fraudulent transfer, reorganization, moratorium and other
       laws of general applicability relating to or affecting creditors' rights
       and to general equity principles (regardless of whether such enforcement
       is considered in a proceeding in equity or at law); the Indenture has
       been fully and validly authorized by the Company, is qualified under,
       and complies with, the Trust Indenture Act  and, when duly executed and
       delivered by the Company and the Trustee, will constitute a valid and

       Company in accordance with its terms, subject to bankruptcy, insolvency,
       fraudulent transfer, reorganization, moratorium and other laws of
       general applicability relating to or affecting creditors' rights and to

       thereof contained in the Prospectus;

               (s)    The Trust Agreement has been duly and validly authorized
       by the Company, is qualified under, and complies with, the Trust
       Indenture Act and when


<PAGE>


       validly executed and delivered by the Company and the trustees
       thereto, will constitute a valid and legally binding obligation
       of the Company, enforceable in accordance with its terms, subject
       to bankruptcy, insolvency, fraudulent transfer, reorganization,
       moratorium and other laws of general applicability relating to or
       affecting creditors' rights and to general equity principles (regardless

       "Governmental Licenses") issued by the appropriate federal, state, local
       or foreign regulatory agencies or bodies necessary to conduct the
       business now operated by them, except where the failure to possess such
       Governmental Licenses, would not, singly or in the aggregate, have a
       Material Adverse Effect; the Company and its subsidiaries are in
       compliance with the terms and conditions of all such Governmental
       Licenses, except where the failure so to comply would not, singly or in
       the aggregate, have a Material Adverse Effect; all of the Governmental
       Licenses are valid and in full force and effect, except when the
       invalidity of such Governmental Licenses or the failure of such
       Governmental Licenses to be in full force and effect would not have a
       Material Adverse Effect; and neither the Company nor any of its
       subsidiaries has received any notice of proceedings relating to the
       revocation or modification of any such Governmental Licenses which,
       singly or in the aggregate, if the subject of an unfavorable decision,
       ruling or finding, would reasonably be expected to result in a Material
       Adverse Effect;

               (w)    Each of the Company and its subsidiaries has
       (i) satisfactory title to its oil and gas properties, except for any

       defects except such as are described or incorporated by reference in the
       Prospectus or such as do not materially affect the value of the
       properties of the Company and its subsidiaries, considered as one
       enterprise, and do not interfere with the use made and proposed to be
       made of such properties, by the Company and its subsidiaries, considered
       as one enterprise; and all of the leases and subleases material to the
       business of the Company and its subsidiaries, considered as one
       enterprise, and under which the Company or any of its subsidiaries holds
       properties described in the Prospectus, are in full force and effect,
       and neither the Company nor


<PAGE>


       any of its subsidiaries has any notice of any material claim of
       any sort that has been asserted by anyone adverse to the rights
       of the Company or its subsidiaries under any of the leases or
       subleases mentioned above, or affecting or questioning the rights of
       such the Company or any subsidiary thereof to the continued possession
       of the leased or subleased premises under any such lease or sublease;

               (x)    Except as described in the Prospectus or except for such

       administrative order, consent, decree or judgment, relating to pollution
       or protection of human health, the environment (including, without
       limitation, ambient air, surface water, groundwater, land surface or
       subsurface strata) or wildlife, including, without limitation, laws and
       regulations relating to the release or threatened release of chemicals,
       pollutants, contaminants, wastes, toxic substances, hazardous
       substances, petroleum or petroleum products (collectively, "Hazardous

       affecting the Company or its subsidiaries relating to Hazardous
       Materials or Environmental Laws;

               (y)    Within the preceding six months, none of the Trust, the
       Company or any other person acting on behalf of the Trust or the Company
       (other than the Underwriters, as to whom the Company makes no
       representation) has offered or sold to any person any Securities, or any
       securities of the same or a similar class as the Securities, other than
       Securities offered or sold to the Underwriters hereunder; and

               (z)    None of the transactions contemplated by this Agreement
       (including, without limitation, the use of the proceeds from the sale of
       the Securities) will violate or result in a violation of Section 7 of
       the Exchange Act, or any regulation promulgated thereunder, including,
       without limitation, Regulations G, T, U, and X of the Board of Governors
       of the Federal Reserve System.

       2.      Subject to the terms and conditions herein set forth, (a) the

                      (iii)  The Guarantee and the Debentures have been duly

              with the terms of the Indenture) when delivered and paid for in
              accordance with the terms of the Underwriting Agreement, will
              constitute valid and legally binding obligations of the

              principles (regardless of whether such enforcement is
              considered in a proceeding in equity or at law); and the

              this Agreement, the Guarantee, or the Indenture, except such as
              have been obtained under the Act and the Trust Indenture Act,
              such as may be required under the Act in connection with the

              such consents, approvals,


<PAGE>

              authorizations, registrations or qualifications as may be

              with the purchase and distribution of the Securities by the

                      (vi)   The statements set forth in the Prospectus under
              the caption "Description of the Debentures" "Description of
              Capital Stock" and "Description of the QUIPS," insofar as they
              purport to describe legal matters, fairly present in all
              material respects the matters set forth therein;

                      (vii)  The Company is not an "investment company" or an
              entity "controlled" by an "investment company", as such terms
              are defined in the Investment Company Act; and

                      (viii) The Registration Statement and the Prospectus
              and any further amendments and supplements thereto made by the
              Company prior to the Time of Delivery (other than (a) the
              financial statements and related schedules therein, including
              the notes thereto and the auditor's report thereon, (b) the
              summary reserve report of Ryder Scott Petroleum Engineers
              contained therein, (c) the other financial and reserve
              information included or incorporated by reference therein and
              (d) the exhibits thereto, as to which such counsel need express
              no opinion) appeared on the face thereof as of the effective
              date of the Registration Statement to be appropriately
              responsive in all material respects to the requirements of the
              Act and the rules and regulations thereunder; although they do
              not assume any responsibility for the accuracy, completeness or
              fairness of the statements contained in the Registration
              Statement or the Prospectus, except to the extent stated in
              paragraph (vi) of this Section 7(d), no facts have come to such
              counsel's attention which lead such counsel to believe that as
              of its effective date, the Registration Statement or any
              further amendment thereto made by the Company prior to the Time
              of Delivery (other than (a) the financial statements and
              related schedules therein, including the notes thereto and the
              auditor's report thereon, (b) the summary reserve report of
              Ryder Scott Petroleum Engineers contained therein, (c) the
              other financial and reserve information included or
              incorporated by reference therein and (d) the exhibits thereto,
              as to which such counsel need not comment) contained an untrue
              statement of a material fact or omitted to state a material
              fact required to be stated therein or necessary to make the
              statements therein not misleading or that, as of its date, the
              Prospectus or any further amendment or supplement thereto made
              by the Company prior to the Time of Delivery (other than (a)
              the financial statements and related schedules therein,
              including the notes thereto and the auditor's report therein,
              (b) the summary reserve report of Ryder Scott Petroleum
              Engineers contained therein, (c) the other financial and
              reserve information included or incorporated by reference
              therein and (d) the exhibits thereto, as to which such counsel
              need not comment) contained an untrue statement of a material
              fact or omitted to state a material fact necessary to make the
              statements therein, in the light of the circumstances under
              which they were made, not misleading, and they do not know of
              any contracts or other documents of a character required to be
              filed as an exhibit to the Registration Statement or required
              to be incorporated by reference into the Prospectus or required
              to be described in the Registration Statement or the Prospectus
              which are not filed or incorporated by reference or described.

              at the Time of Delivery and the compliance by the Company with
              all of the provisions of the Guarantee and the Debentures, the

              with or result in a breach or violation of any of the terms or
              provisions of, or constitute a default under, any indenture,
              mortgage, deed of trust, loan agreement or other agreement or
              instrument known to such counsel to which the Company or any of

              which any of the property or assets of the Company or any of
              its subsidiaries is subject, nor will such actions result in
              any violation of the provisions of the Restated Certificate of
              Incorporation or Amended and Restated By-laws of the Company
              or any statute or any order, rule or regulation of any court
              or governmental agency or body having jurisdiction over the

                      (v)    To his knowledge, there are no legal or
              governmental proceedings pending to which the Company
              or any of its subsidiaries is a party or of which any property
              of the Company or any of its subsidiaries is the subject
              which, if determined adversely to the Company or any of its
              subsidiaries, would individually or in the aggregate have a
              Material Adverse Effect; and, to such counsel's knowledge, no
              such proceedings are threatened or contemplated by
              governmental authorities or threatened by others;

                      (vi)   Neither the Company nor any of its subsidiaries
              is in violation of its certificate of incorporation or by-laws
              or in default in the performance or observance of any material
              obligation, covenant or condition contained in any indenture,
              mortgage, deed of trust, loan agreement, lease or other
              agreement or instrument to which it is a party or by which it
              or any of its properties may be bound;

                      (vii)  The documents incorporated by reference in the
              Prospectus or any further amendment or supplement thereto made

              such counsel need express no opinion), when they became
              effective or were filed with the Commission, as the case may
              be, complied as to form in all material respects with the
              requirements of the Act or the Exchange Act, as applicable, and
              the rules and regulations of the Commission thereunder; and he
              has no reason to believe that any of such documents, when such
              documents became effective or were so filed, as the case may
              be, contained, in the case of a registration statement which
              became effective under the Act, an untrue statement of a
              material fact or omitted to state a material fact required to
              be stated therein or necessary to make the statements therein
              not misleading, or, in the case of other documents which were
              filed under the Act or the Exchange Act with the Commission, an
              untrue statement of a material fact or omitted to state a
              material fact necessary in order to make the statements
              therein, in the light of the circumstances under which they
              were made when such documents were so filed, not misleading; and

                      (viii) The Registration Statement and the Prospectus
              and any further amendments and supplements thereto made by the
              Company prior to the Time of Delivery (other than the financial
              statements and related schedules therein, as to which such
              counsel need express no opinion) comply as to form in all
              material respects with the requirements of the Act and the
              Trust Indenture Act and the rules and regulations thereunder;
              although they do not assume any responsibility for the
              accuracy, completeness or fairness of the statements contained
              in the Registration Statement or the Prospectus, he has no
              reason to believe that, as of its effective date, the
              Registration Statement or any further amendment thereto made by
              the Company prior to the Time of Delivery (other than the
              financial statements and related schedules


<PAGE>


       therein, as to which such counsel need express no opinion) contained an
       untrue statement of a material fact or omitted to state a material fact
       required to be stated therein or necessary to make the statements
       therein not misleading or that, as of its date, the Prospectus or any
       further amendment or supplement thereto made by the Company prior to the
       Time of Delivery (other than the financial statements and related
       schedules therein and the Forms T-1; as to which such counsel need
       express no opinion) contained an untrue statement of a material fact or
       omitted to state a material fact necessary to make the statements
       therein and the Forms T-1, in the light of the circumstances under which
       they were made, not misleading or that, as of the Time of Delivery,
       either the Registration Statement or the Prospectus or any further
       amendment or supplement thereto made by the Company prior to the Time of
       Delivery (other than the financial statements and related schedules
       therein, as to which such counsel need express no opinion) contains an
       untrue statement of a material fact or omits to state a material fact
       necessary to make the statements therein and the Forms T-1, in the light
       of the circumstances under which they were made, not misleading; and
       they do not know of any amendment to the Registration Statement required
       to be filed or of any contracts or other documents of a character
       required to be filed as an exhibit to the Registration Statement or
       required to be incorporated by reference into the Prospectus or required
       to be described in the Registration Statement or the Prospectus which
       are not filed or incorporated by reference or described as required.

       In rendering such opinion, such counsel may state that he expresses no
opinion as to the laws of any jurisdiction other than the federal laws of the
United States, the laws of the State of New York and the General Corporation Law
of the State of Delaware, except with respect to the matters set forth in (i),
(ii) and (iii) of this Section 7(f).

       (g)     On the date of the Prospectus at a time prior to the execution of
this Agreement, at 9:30 a.m., New York City time, on the effective date of any
post-effective amendment to the Registration Statement filed subsequent to the
date of this Agreement and also at the Time of Delivery, Arthur Andersen LLP
shall have furnished to you a letter or letters, dated the respective dates of
delivery thereof, in form and substance satisfactory to you, to the effect set
forth in Annex I hereto (the executed copy of the letter delivered prior to the
execution of this Agreement is attached as Annex I(a) hereto and a draft of the
form of letter to be delivered on the effective date of any post-effective
amendment to the Registration Statement and as of the Time of Delivery is
attached as Annex I(b) hereto");

       (h)     (i)  Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus any loss or interference with its
business from fire, explosion, flood or other calamity, whether or not covered
by insurance, or from any labor dispute or court or governmental action, order
or decree, otherwise than as set forth or contemplated in the Prospectus, and
(ii) since the respective dates as of which information is given in the
Prospectus there shall not have been any change in the capital stock or
long-term debt of the Company or any of its subsidiaries or any change, or any
development involving a prospective change, in or affecting the general affairs,
management, financial position, shareholders' equity or results of operations of
the Company and its subsidiaries, otherwise than as set forth or contemplated in
the Prospectus, the effect of which, in any such case described in clause (i) or
(ii), is in the judgment of the Representatives so material and adverse as to
make it impracticable or inadvisable to proceed with the public offering or the
delivery of the Securities being issued at the Time of Delivery on the terms and
in the manner contemplated in the


<PAGE>


Prospectus;

       (i)     On or after the date hereof (i) no downgrading shall have
occurred in the rating accorded the Company's debt securities by any "nationally
recognized statistical rating organization", as that term is defined by the
Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such
organization shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the Company's
debt securities;

       (j)     On or after the date hereof there shall not have occurred any of
the following: (i) a suspension or material limitation in trading in securities
generally on the New York Stock Exchange; (ii) a suspension or material
limitation in trading in the Company's securities on the New York Stock
Exchange; (iii) a general moratorium on commercial banking activities declared
by either Federal or New York or Texas State authorities; or (iv) the outbreak
or escalation of hostilities involving the United States or the declaration by
the United States of a national emergency or war, if the effect of any such
event specified in this clause (iv) in the judgment of the Underwriters makes it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Securities being issued at the Time of Delivery on the terms and in the
manner contemplated in the Prospectus;

       (k)     The shares of Common Stock issuable upon conversion of the
Securities will be duly listed, subject to notice of issuance, on the New York
Stock Exchange;

       (l)     The Company shall have complied with the provisions of Section
5(c) hereof with respect to the furnishing of prospectuses on the Houston
Business Day next succeeding the date of this Agreement;

       (m)     The Company shall have furnished or caused to be furnished to you
at the Time of Delivery certificates of officers of the Company satisfactory to
you as to the accuracy of the representations and warranties of the Company
herein at and as of the Time of Delivery, as to the performance by the Company
of all of its obligations hereunder to be performed at or prior to the Time of
Delivery, as to the matters set forth in subsections (a) and (e) of this Section
and as to such other matters as you may reasonably request; and

       (n)     During a period of 90 days from the date hereof, the Company and
the Trust will not, without the prior written consent of Goldman, Sachs & Co.,
sell, offer to sell, grant any option (excluding options granted under the
Company's long-term employee incentive plans) for the sale of, or otherwise
dispose of any Securities, Common Trust Securities or Debentures, any security
convertible into or exchangeable into or exercisable for, the Securities, Common
Trust Securities or the Debentures or any debt substantially similar to the
Debentures or any equity securities substantially similar to the Securities or
the Common Trust Securities (except as issued hereunder) or any Common Stock
(except shares of Common Stock issuable upon the exercise of options granted
under the Company's long term incentive plans) or any security convertible into
or exchangeable into or exercisable for Common Stock or any equity security
substantially similar to the Common Stock; and the Company shall have obtained a
written undertaking, for delivery to the Underwriters, signed by each director
and officer of the Company stating that such officer or director has agreed to
be bound by this provision.

       8.      (a)  The Company and the Trust will jointly and severally
indemnify and hold


<PAGE>


harmless each Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter may become subject, under the Act
or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
and will reimburse each Underwriter for any legal or other expenses
reasonably incurred by such Underwriter in connection with investigating or
defending any such action or claim as such expenses are incurred; PROVIDED,
HOWEVER, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon
an untrue statement or alleged untrue statement or omission or alleged
omission made in any Preliminary Prospectus, the Registration Statement or
the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any
Underwriter through Goldman, Sachs & Co. expressly for use therein.

       (b)     Each Underwriter will indemnify and hold harmless the Company and
the Trust against any losses, claims, damages or liabilities to which the
Company may become subject, under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through Goldman, Sachs
& Co. expressly for use therein; and will reimburse the Company for any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending any such action or claim as such expenses are
incurred.

       (c)     Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection.  In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation.  No
indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any


<PAGE>


judgment with respect to, any pending or threatened action or claim in
respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes
an unconditional release of the indemnified party from all liability arising
out of such action or claim and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of any
indemnified party.

       (d)     If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Trust on the one hand and the
Underwriters on the other from the offering of the Securities.  If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (c) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Trust on the one hand and the Underwriters on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations.  The relative benefits received
by the Company and the Trust on the one hand and the Underwriters on the other
shall be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Trust bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus.  The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company and the Trust on the one hand or the Underwriters on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Company, the Trust  and the
Underwriters agree that it would not be just and equitable if contribution
pursuant to this subsection (d) were determined by PRO RATA allocation (even if
the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above in this subsection (d).  The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim.  Notwithstanding the provisions of this subsection (d), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Underwriters' obligations in this subsection
(d) to contribute are several in proportion to their respective underwriting
obligations and not joint.

       (e)     The obligations of the Company and the Trust under this Section 8
shall be in addition to any liability which the Company and the Trust may
otherwise have and shall extend,


<PAGE>


upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the
same terms and conditions, to each officer and director of the Company and
the Trust (including any person who, with his or her consent, is named in the
Registration Statement as about to become a director of the Company) and to
each person, if any, who controls the Company or the Trust within the meaning
of the Act.

       9.      (a)  If any Underwriter shall default in its obligation to
purchase the Securities which it has agreed to purchase hereunder, you may in
your discretion arrange for you or another party or other parties to purchase
such Securities on the terms contained herein at a Time of Delivery.  If within
thirty-six hours after such default by any Underwriter you do not arrange for
the purchase of such Securities, then the Company and the Trust shall be
entitled to a further period of thirty-six hours within which to procure another
party or other parties satisfactory to you to purchase such Securities on such
terms.  In the event that, within the respective prescribed periods, you notify
the Company and the Trust that you have so arranged for the purchase of such
Securities, or the Company or the Trust notifies you that it has so arranged for
the purchase of such Securities, you or the Company or the Trust shall have the
right to postpone the Time of Delivery for a period of not more than  seven
days, in order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary.  The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Securities.

       (b)     If, after giving effect to any arrangements for the purchase of
the Securities of a defaulting Underwriter or Underwriters by you and the
Company or the Trust as provided in subsection (a) above, the aggregate number
of such Securities which remains unpurchased does not exceed one-eleventh of the
aggregate number of all the Securities to be purchased at the Time of Delivery,
then the Company and the Trust shall have the right to require each
non-defaulting Underwriter to purchase the number of Securities which such
Underwriter agreed to purchase hereunder at the Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Securities which such Underwriter agreed to
purchase hereunder) of the Securities of such defaulting Underwriter or
Underwriters for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

       (c)     If, after giving effect to any arrangements for the purchase of
the Securities of a defaulting Underwriter or Underwriters by you and the
Company or the Trust as provided in subsection (a) above, the aggregate number
of Securities which remains unpurchased exceeds one-eleventh of the aggregate
number of all the Securities to be purchased at the Time of Delivery, or if the
Company or the Trust shall not exercise the right described in subsection (b)
above to require non-defaulting Underwriters to purchase Securities of a
defaulting Underwriter or Underwriters, then this Agreement shall thereupon
terminate, without liability on the part of any non-defaulting Underwriter, the
Company or the Trust, except for the expenses to be borne by the Company and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.


<PAGE>


       10.     The respective indemnities, agreements, representations,
warranties and other statements of the Company, the Trust and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, the Company or the Trust, or any officer or director or controlling
person of the Company or the Trust, and shall survive delivery of and payment
for the Securities.

       11.     If this Agreement shall be terminated pursuant to Section 9
hereof, the Company and the Trust shall not then be under any liability to any
Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other
reason, any Securities are not delivered by or on behalf of the Trust as
provided herein, the Company and the Trust will jointly and severally reimburse
the Underwriters through you for all out-of-pocket expenses approved in writing
by you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Securities, but the Company shall then be under no further liability to any
Underwriter except as provided in Sections 6 and 8 hereof.

       12.     In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
Underwriters.

       All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the Underwriters in care of Goldman, Sachs &
Co., 32 Old Slip, 21st Floor, New York, New York 10005, Attention: Registration
Department; if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Secretary and if to the Trust shall be
delivered or sent by mail, telex or facsimile transmission to (713) 297-4970;
PROVIDED, HOWEVER, that any notice to an Underwriter pursuant to Section 8(c)
hereof shall be delivered or sent by mail, telex or facsimile transmission to
such Underwriter at its address set forth in its Underwriters' Questionnaire, or
telex constituting such Questionnaire, which address will be supplied to the
Company by you upon request.  Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

       13.     This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Trust, the Company and, to the extent provided
in Sections 8 and 10 hereof, the officers and directors of the Company and each
person who controls the Company or any Underwriter, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement. No purchaser of
any of the Securities from any Underwriter shall be deemed a successor or assign
by reason merely of such purchase.

       14.     Time shall be of the essence of this Agreement.  As used herein,
the term "business day" shall mean any day when the Commission's office in
Washington, D.C.  is open for business,  unless otherwise specified.

       15.     THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH


<PAGE>


THE LAWS OF THE STATE OF NEW YORK.

       16.     This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such respective counterparts shall together constitute one and
the same instrument.







<PAGE>


       If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company, the Trust and each of the Underwriters
plus one for each counsel counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement between each of the Underwriters and
the Company.  It is understood that your acceptance of this letter on behalf of
each of the Underwriters is pursuant to the authority set forth in a form of
Agreement among Underwriters, the form of which shall be submitted to the
Company for examination upon request, but without warranty on your part as to
the authority of the signers thereof.

                                   Very truly yours,

                           DESCRIPTION OF COMFORT LETTER


       Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

               (i)    They are independent certified public accountants with
       respect to the Company and its subsidiaries within the meaning of the
       Act and the applicable published rules and regulations thereunder;

               (ii)   In their opinion, the financial statements and any
       supplementary financial information and schedules (and, if applicable,
       prospective financial statements and/or pro forma financial information)
       examined by them and included or incorporated by reference in the
       Registration Statement or the Prospectus comply as to form in all
       material respects with the applicable accounting requirements of the Act
       or the Exchange Act, as applicable, and the related published rules and
       regulations thereunder; and, if applicable, they have made a review in
       accordance with standards established by the American Institute of
       Certified Public Accountants of the consolidated interim financial
       statements, selected financial data, pro forma financial information,
       prospective financial statements and/or condensed financial statements
       derived from audited financial statements of the Company for the periods
       specified in such letter, as indicated in their reports thereon, copies
       of which have been [SEPARATELY] furnished to the representatives of the
       Underwriters (the "Representatives")[AND ARE ATTACHED HERETO];

               (iii)  They have made a review in accordance with standards
       established by the American Institute of Certified Public Accountants of
       the unaudited condensed consolidated statement of income, consolidated
       balance sheets and consolidated statements of cash flows included in the
       Prospectus and/or included in the Company's quarterly report on Form
       10-Q incorporated by reference into the Prospectus as indicated in their
       reports thereon copies of which [HAVE BEEN SEPARATELY FURNISHED TO THE
       REPRESENTATIVES][ARE ATTACHED HERETO]; and on the basis of specified
       procedures including inquiries of officials of the Company who have
       responsibility for financial and accounting matters regarding whether
       the unaudited condensed consolidated financial statements referred to in
       paragraph (vi)(A)(i) below comply as to form in the related in all
       material respects with the applicable accounting requirements of the
       [ACT AND THE EXCHANGE] Act and the related published rules and
       regulations, nothing came to their attention that caused them to believe
       that the unaudited condensed consolidated financial statements do not
       comply as to form in all material respects with the applicable
       accounting requirements of the [ACT AND THE EXCHANGE] Act and the
       related published rules and regulations;

               (iv)   The unaudited selected financial information with respect
       to the consolidated results of operations and financial position of the
       Company for the five most recent fiscal years included in the Prospectus
       and included or incorporated by


<PAGE>


       reference in Item 6 of the Company's Annual Report on Form 10-K
       for the most recent fiscal year agrees with the corresponding amounts
       (after restatement where applicable) in the audited consolidated
       financial statements for such five fiscal years which were included
       or incorporated by reference in the Company's Annual Reports on
       Form 10-K for such fiscal years;

               (v)    They have compared the information in the Prospectus
       under selected captions with the disclosure requirements of Regulation
       S-K and on the basis of limited procedures specified in such letter
       nothing came to their attention as a result of the foregoing procedures
       that caused them to believe that this information does not conform in
       all material respects with the disclosure requirements of Items 301,
       302, 402 and 503(d), respectively, of Regulation S-K;

               (vi)   On the basis of limited procedures, not constituting an
       examination in accordance with generally accepted auditing standards,
       consisting of a reading of the unaudited financial statements and other
       information referred to below, a reading of the latest available interim
       financial statements of the Company and its subsidiaries, inspection of
       the minute books of the Company and its subsidiaries since the date of
       the latest audited financial statements included or incorporated by
       reference in the Prospectus, inquiries of officials of the Company and
       its subsidiaries responsible for financial and accounting matters and

               described in such letter; and

                      (F)     for the period from the date of the latest

shall be provided within 120 days of the end of each Fiscal Year).

        SECTION 2.05.  Evidence of Compliance with Conditions Precedent.

        Each of the Sponsor and the Regular Trustees on behalf of the Trust
shall provide to the Property Trustee such evidence of compliance with any
conditions precedent provided for in this Declaration which relate to any of the
matters set forth in ss. 314(c) of the Trust Indenture Act. Any certificate or
opinion required to be given by an officer pursuant to ss. 314(c) may be given
in the form of an Officers' Certificate.

        SECTION 2.06.  Events of Default; Waiver.

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

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

             (ii) requires the consent or vote of the holders of greater than a
       majority in aggregate principal amount of the Debentures (a "Super
       Majority") to be waived under the Indenture, 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 Preferred
       Securities that the relevant Super Majority represents of the aggregate
       principal amount of the Debentures outstanding.

The foregoing provisions of this Section 2.06(a) 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. Upon such waiver, any

                                       10
<PAGE>

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

                                       17
<PAGE>

interest of the Property Trustee to the Debentures shall vest automatically in

or not conveyancing documents with regard to the Debentures have been executed
and delivered.

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

       (c)   The Property Trustee shall:

             (i) establish and maintain a segregated non-interest bearing bank
       account (the "Property Account") in the name of and under the exclusive
       control of the Property Trustee on behalf of the Holders of the
       Securities and on the receipt of payments of funds made in respect of the
       Debentures held by the Property Trustee, deposit such funds into the
       Property Account and, without any further acts of the Property Trustee or
       the Regular Trustees, promptly make payments to the Holders of the
       Preferred Securities and Common Securities from the Property Account in
       accordance with Section 6.01. Funds in the Property Account shall be held
       uninvested, and without liability for interest thereon, until disbursed
       in accordance with this Declaration. The Property Account shall be an
       account which is maintained with a banking institution whose long term
       unsecured indebtedness is rated by a "nationally recognized statistical
       rating organization", as such term is defined for purposes of Rule
       436(g)(2) under the Securities Act, at least investment grade;

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

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

       (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

election to defer payments of interest on the Debentures by extending the
interest payment period with respect thereto or (ii) the shortening of the
maturity date of the Debentures in accordance with the terms of the
Supplemental Indenture.

       (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

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

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.

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

        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

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

        (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.

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 that acts as the Property Trustee also acts as the Delaware
       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
       officers, directors or employees of Pogo;

             (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
       the Delaware Trustee and Section 3.11 shall have no application; and

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

Each Trustee shall be either a natural person at least 21 years of age or a
legal entity which shall act through one or more duly appointed representatives.

        (b) The initial Regular Trustees shall be:

            John O. McCoy, Jr.
            John W. Elsenshans
            Gerald A. Morton

            c/o POGO PRODUCING COMPANY
            5 Greenway Plaza, Suite 2700
            Houston, Texas  77046

        (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.

                                    ARTICLE 6
                                  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 a Related Party of the
Sponsor; provided that, any such transfer is subject to the condition
precedent that the transferor obtain the written opinion of nationally
recognized independent counsel experienced in such matters that such transfer
would not cause more than an insubstantial risk that: (i) the Trust would not
be classified for United States Federal income tax purposes as a granter
trust; and (ii) the Trust would be an Investment Company required to register
under the Investment Company Act or the transferee would become an Investment
Company required to register under the Investment Company Act.  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.

        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
Certificate issued pursuant to this section shall constitute conclusive evidence
of an

                                       38

ownership interest in the relevant Securities, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

        SECTION 10.01.  Exculpation.

Indemnified Person in good faith on behalf of the Trust and in a manner such
Indemnified Person reasonably believed to be within the scope of the authority

such acts or omissions.

       (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports

competence and who has been selected with reasonable care by or on behalf of the
Trust, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits, losses or any other facts
pertinent to the existence and amount of assets from which Distributions to
Holders of Securities might properly be paid.

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

        SECTION 10.02.  Indemnification.

       (a) To the fullest extent permitted by applicable law, the Sponsor shall

       (b) The provisions of this Section 10.02 shall survive the termination of
this Declaration or the resignation or removal of any Trustee.

        SECTION 10.03.  Outside Business.

        The Sponsor and any Trustee (in the case of the Property Trustee,
subject to Section 5.01(c)) may engage in or possess an interest in other
business ventures of any nature or description, independently or with others,
similar or dissimilar to the business of the Trust, and the Trust and the
Holders of Securities shall have no rights by virtue of this Declaration in and
to such independent ventures or the income or profits derived therefrom, and the
pursuit of any such venture, even if competitive with the business of the Trust,
shall not be deemed wrongful or improper. Neither the Sponsor nor any Trustee
shall be obligated to present any particular investment or other opportunity to
the Trust even if such opportunity is of a character that, if presented to the
Trust, could be taken by the Trust, and the Sponsor or any Trustee shall have
the right to take for its own account (individually or as a partner or
fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Trustee may engage or be interested in any financial or other
transaction with the Sponsor or any Affiliate of the Sponsor or may act as
depository for, trustee or agent for, or act on any committee or body of holders
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 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;

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

for purposes of United States Federal income taxation as a grantor trust; (y)

ambiguity, (ii) correct or supplement any provision in this Declaration that
may be defective or inconsistent with any other provision of this

Rule 3a-5 or Rule 3a-7 (if the Trust is excluded from the definition of an
Investment Company solely by reason of Rule 3a-5 or 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

Company under the Investment Company Act, and (vii) pursuant to Section 5.02,

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

        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.

        SECTION 14.07.  Intention of the Parties.

        It is the intention of the parties hereto that the Trust not be

        The Trust's obligations hereunder are intended to be the obligations of
the Trust and no recourse for the payment of Distributions, or for any claim
upon the Securities or otherwise in respect thereof, shall be had against any
Holder of Securities or any Affiliate of a Holder of Securities, solely by
reason of such Person's being a Holder of Securities or an Affiliate of a Holder
of Securities, it being understood that the Holder of Securities, solely by
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 1/2% 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 1/2% (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 a cash
        redemption price per Preferred Security equal to the Optional
        Redemption Price (as such term is defined in the Supplemental
        Indenture) per $50 principal amount of Debenture. 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 Sponsor 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 and the Common 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, within 90 days of the occurrence of such Tax
        Event 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 and Common Securities with an aggregate
        liquidation amount equal to the aggregate principal amount of the
        Debentures so redeemed will be redeemed by the Trust at a cash
        redemption price per Preferred Security equal to the Tax Redemption
        Price per $50 principal amount of Debentures, plus accrued and unpaid
        Distributions thereon to the redemption date on a pro rata basis. The
        Common Securites will be redeemed Pro Rata with the Preferred
        Securities, except that if an Event of Default has occurred and is
        continuing, the Preferred Securites will have a priority over the
        common Securities with respect to payment of the Tax Redemption Price.

                        (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 Preferred Securities and Common
                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 Preferred Securities and Common
                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

                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
                Global Certificates, the Property Trustee shall provide for
                the selection for exchange of a portion of the Global
                Certificate representing the Preferred Securities on a pro
                rata basis and (iii) if outstanding Preferred Securities are
                represented by both Global Certificates and Book-Entry
                Preferred Securities Certificates, the Property Trustee shall
                select the portion of the Global Certificate representing the
                Preferred Securities 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 Preferred
                Securities 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 Global
                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 from
                independent nationally recognized tax 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 from independent nationally
                recognized 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 free from any preemptive or other
        similar rights, 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
        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 Exhibit B, 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 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

                                      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.

the Trust and designated the 6 1/2% Cumulative Quarterly Income Convertible

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

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 1/2% (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.

                               CONVERSION REQUEST

        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.

                                                                       EXHIBIT C

                                    TERMS OF
                                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 1/2% 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 1/2% (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 a cash
        redemption price per Common Security equal to the Optional Redemption
        Price (as such term is defined in the Supplemental Indenture per $50
        principal amount of Debenture, 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 Sponsor 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 and Prefered 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 within 90 days of the occurrence of such
        Tax Event, 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 and 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 a cash
        redemption price equal to, the Tax Redemption Price, plus accrued and
        unpaid Distributions thereon to the redemption date on a pro rata
        basis per $50 principal amount of Debentures.  The Common Securities
        will be redeemed Pro Rata with the Preferred Securities, except that
        if an Event of Default has occurred and is continuing, the Preferred
        Securities will have a priority over the Common Securities with
        respect to payment of the Tax Redemption Price.

                        (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 Common Securities and Preferred
                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 Common Securities and Preferred
                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.

<PAGE>

                        (v) "Tax Event" means that the Sponsor and the Regular
                Trustees shall have received an Opinion of Counsel from
                independent nationally recognized tax 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 from independent nationally recognized 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 free from any preemptive or
        other similar rights, 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.

                             NAME: JOHN W. ELSENHANS
                             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 1/2% (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 Common Securities
Certificate.

<PAGE>

    All Debentures of any one series shall be substantially identical except

    If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth  the terms of the series.

    SECTION 2.02.  FORM OF DEBENTURE AND TRUSTEE'S CERTIFICATE.   The
Debentures of any series and the Trustee's certificate of authentication to
be borne by such Debentures shall be substantially of the tenor and purport
as set forth in one or more indentures supplemental hereto or as provided in

such letters, numbers or other marks of identification or designation and
such legends or endorsements typewritten, printed, lithographed or engraved
thereon as the Company may deem appropriate and as are not inconsistent with
the provisions of this Indenture, 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
Debentures of that series may be listed or traded, or to conform to usage.

    SECTION 2.03.  DATE AND DENOMINATIONS OF DEBENTURES AND PROVISIONS FOR
PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.  The Debentures shall be issuable
as registered Debentures and in the denominations of $25 or any integral

series shall bear interest payable on the dates and at the rate specified
with respect to that series. The principal of and the interest on the
Debentures of any series, as well as any premium thereon in case of
redemption thereof prior to maturity, shall, subject to Section 2.01(8) and
(15), be payable in the coin or currency of the United States of America
which at the time is legal tender for public and private debt, at Place of
Payment.  Each Debenture shall be dated the date of its authentication.
Interest on the Debentures shall be computed on the basis of a 360-day year
composed of twelve 30-day months, subject to Section 2.01(5).

    The interest installment on any Debenture which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date for
Debentures of that series shall be paid to the person in whose name said
Debenture (or one or more Predecessor Debentures) is registered at the close
of business on the regular record date for such interest installment. In the
event that any Debenture of a particular series or portion thereof is called
for redemption and the redemption date is subsequent to a regular record date
with respect to any Interest Payment Date and prior to such Interest Payment
Date, interest on such Debenture will be paid upon presentation and surrender
of such Debenture as provided in Section 3.03.

    Any interest on any Debenture which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date for Debentures of the
same series (herein called "Defaulted Interest") shall forthwith cease to be
payable to the registered holder on the

                                       11
<PAGE>

relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Company, at its election, as provided
in clause (1) or clause (2) below:

            (1)  The Company may make payment of any Defaulted Interest on
            Debentures to the persons in whose names such Debentures (or
            their respective Predecessor Debentures) are registered at the
            close of business on a special record date for the payment of
            such Defaulted Interest, which shall be fixed in the following
            manner: the Company shall notify the Trustee in writing of the
            amount of Defaulted Interest proposed to be paid on each such
            Debenture and the date of the proposed payment, and at the same
            time the Company shall deposit with the Trustee an amount of
            money equal to the aggregate amount proposed to be paid in
            respect of such Defaulted Interest or shall make arrangements
            satisfactory to the Trustee for such deposit prior to the date of
            the proposed payment, such money when deposited to be held in
            trust for the benefit of the persons entitled to such Defaulted
            Interest as in this clause provided. Thereupon the Trustee shall
            fix a special record date for the payment of such Defaulted
            Interest which shall not be more than 15 nor less than 10 days
            prior to the date of the proposed payment and not less than 10
            days after the receipt by the Trustee of the notice of the
            proposed payment. The Trustee shall promptly notify the Company
            of such special record date and, in the name and at the expense
            of the  Company, shall cause notice of the proposed payment of
            such Defaulted Interest and the special record date therefor to
            be mailed, first class postage prepaid, to each Debentureholder
            at his or her address as it appears in the Debenture Register,
            not less than 10 days prior to such special record date. Notice
            of the proposed payment of such Defaulted Interest and the
            special record date therefor having been mailed as aforesaid,
            such Defaulted Interest shall be paid to the persons in whose
            names such Debentures (or their Predecessor Debentures) are
            registered on such special record date and shall be no longer
            payable pursuant to the following clause (2).

            (2)  The Company may make payment of any Defaulted Interest on
            any Debentures in any other lawful manner not inconsistent with
            the requirements of any securities exchange or automated
            quotation system on which such Debentures may be listed or
            traded, and upon such notice as may be required by such exchange
            or quotation system, if, after notice given by the Company to the
            Trustee of the proposed payment pursuant to this clause, such
            manner of payment shall be deemed practicable by the Trustee.

    Unless otherwise set forth in a Board Resolution or one or more
indentures supplemental hereto establishing the terms of any series of
Debentures pursuant to Section 2.01 hereof, the term "regular record date" as
used in this Section with respect to a series of Debentures with respect to
any Interest Payment Date for such series shall mean either the fifteenth day
of the month immediately preceding the month in which an Interest Payment

                                       12
<PAGE>

Date established for such series pursuant to Section 2.01 hereof shall occur,
if such Interest Payment Date is the first day of a month, or the last day of
the month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.01 hereof shall occur, if
such Interest Payment Date is the fifteenth day of a month, whether or not
such date is a Business Day.

    Subject to the foregoing provisions of this Section, each Debenture of a
series delivered under this Indenture upon transfer of or in exchange for or
in lieu of any other Debenture of such series shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Debenture.

    SECTION 2.04.  EXECUTION OF DEBENTURES.  The Debentures shall, subject to
the provisions of Section 2.06, be printed on steel engraved borders or fully
or partially engraved, or legibly typed, as the proper officers of the
Company may determine, and shall be signed on behalf of the Company by the
Chairman or Vice Chairman of its Board of Directors or its Chief Executive
Officer, President or one of its Vice Presidents, under its corporate seal
attested by its Secretary or one of its Assistant Secretaries. The signature
of the Chairman, Vice Chairman, Chief Executive Officer, President or a Vice
President and/or the signature of the Secretary or an Assistant Secretary in
attestation of the corporate seal, upon the Debentures, may be in the form of
a manual or facsimile signature and may be imprinted or otherwise reproduced
on the Debentures and for that purpose the Company may use the manual or
facsimile signature of any person who shall have been a Chairman, Vice
Chairman, Chief Executive Officer, President or Vice President, or of any
person who shall have been a Secretary or Assistant Secretary,
notwithstanding the fact that at the time the Debentures shall be
authenticated and delivered or disposed of such person shall have ceased to
be the Chairman, Vice Chairman, President or a Vice President, or the
Secretary or an Assistant Secretary, of the Company, as the case may be. The
seal of the Company may be in the form of a facsimile of the seal of the
Company and may be impressed, affixed, imprinted or otherwise reproduced on
the Debentures.

    Only such Debentures as shall bear thereon a Certificate of
Authentication substantially in the form established for such Debentures,
executed manually by an authorized signatory of the Trustee, or by any
Authenticating Agent with respect to such Debentures, shall be entitled to
the benefits of this Indenture or be valid or obligatory for any purpose.
Such certificate executed by the Trustee, or by any Authenticating Agent
appointed by the Trustee with respect to such Debentures, upon any Debenture
executed by the Company shall be conclusive evidence that the Debenture so
authenticated has been duly authenticated and made available for delivery
hereunder and that the holder is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debenture shall have been authenticated
and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Debenture to the Trustee for cancellation as
provided in Section 2.08, for all purposes of this Indenture such Debenture
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

                                       13
<PAGE>

    At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debentures of any series executed by
the Company to the Trustee for authentication, together with a written order
of the Company for the authentication and delivery of such Debentures, signed
by its President or any Vice President and its Treasurer or any Assistant
Treasurer, and the Trustee in accordance with such written order shall
authenticate and make available for delivery such Debentures.  Each Debenture
shall be dated the date of its authentication by the Trustee.

    In authenticating such Debentures and accepting the additional
responsibilities under this Indenture in relation to such Debentures, the
Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form
and terms thereof have been established in conformity with the provisions of
this Indenture.

    The Trustee shall not be required to authenticate such Debentures if the
issue of  such Debentures pursuant to this Indenture will affect the
Trustee's own rights, duties or immunities under the Debentures and this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee.

    SECTION 2.05.  EXCHANGE OF DEBENTURES.  (a)  Debentures of any series may
be exchanged upon presentation thereof at a Place of Payment, for other
Debentures of such series of authorized denominations, and for a like
aggregate principal amount, upon payment of a sum sufficient to cover any tax
or other governmental charge in relation thereto, all as provided in this
Section.  In respect of any Debentures so surrendered for exchange, the
Company shall execute, the Trustee shall authenticate and such office or
agency shall make available for delivery in exchange therefor the Debenture
or Debentures of the same series which the Debentureholder making the
exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding.

    (b)  The Company shall keep, or cause to be kept, at the Corporate Trust
Office of the Trustee (the register maintained in such office and in any
other office or agency of the Company in a Place of Payment is herein
sometimes collectively referred to as the "Debenture Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
register the Debentures and the transfers of Debentures as in this Article
provided and which at all reasonable times shall be open for inspection by
the Trustee.  The registrar for the purpose of registering Debentures and
transfer of Debentures as herein provided shall be appointed by the Company
(the "Debenture Registrar").  The initial Debenture Registrar shall be the
Trustee.

    Upon surrender for transfer of any Debenture at the office or agency of
the Company in a Place of Payment, the Company shall execute and the Trustee
shall authenticate and deliver, in the name of the transferee or transferees,
one or more new Debentures of the same series as the Debenture presented, of
any authorized denominations and of like tenor and aggregate principal amount.


                                       14
<PAGE>

  All Debentures presented or surrendered for exchange or registration of
transfer, as provided in this Section, shall be accompanied (if so required by
the Company or the Debenture Registrar) by a written instrument or instruments
of transfer, in form satisfactory to the Company or the Debenture Registrar,
duly executed by the registered holder or by his duly authorized attorney in
writing.

  (c)  No service charge shall be made for any exchange or registration of
transfer of Debentures, or issue of new Debentures in case of partial redemption
of any series, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge in relation thereto, other than exchanges
pursuant to Section 2.06, Section 3.03(b) and Section 9.04 not involving any
transfer.

  (d)  The Company shall not be required (i) to issue, exchange or register
the transfer of any Debentures during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of less
than all the outstanding Debentures of the same series and ending at the close
of business on the day of such mailing, nor (ii) to register the transfer of or
exchange any Debentures of any series or portions thereof called for redemption.
The provisions of this Section 2.05 are, with respect to any Global Debenture,
subject to Section 2.11 hereof.


  SECTION 2.06.  TEMPORARY DEBENTURES.  Pending the preparation of definitive
Debentures of any series, the Company may execute, and the Trustee shall
authenticate and make available for delivery, temporary Debentures (printed,
lithographed or typewritten) of any authorized denomination, and substantially
in the form of the definitive Debentures in lieu of which they are issued, but
with such omissions, insertions and variations as may be appropriate for
temporary Debentures, all as may be determined by the Company. Every temporary
Debenture of any series shall be executed by the Company and be authenticated by
the Trustee upon the same conditions and in substantially the same manner, and
with like effect, as the definitive Debentures of such series. Without
unnecessary delay the Company will execute and will furnish definitive
Debentures of such series and thereupon any or all temporary Debentures of such
series may be surrendered in exchange therefor (without charge to the holders),
at a Place of Payment, and upon receipt of a written order of the Company signed
by its President or any Vice President and its Treasurer or any Assistant
Treasurer, the Trustee shall authenticate and deliver in exchange for such
temporary Debentures an equal aggregate principal amount of definitive
Debentures of such series, unless the Company advises the Trustee to the effect
that definitive Debentures need not be executed and furnished until further
notice from the Company. Until so exchanged, the temporary Debentures of such
series shall be entitled to the same benefits under this Indenture as definitive
Debentures of such series authenticated and delivered hereunder.


  SECTION 2.07.  MUTILATED, DESTROYED, LOST OR STOLEN DEBENTURES.  In case
any temporary or definitive Debenture shall become mutilated or be destroyed,
lost or stolen, the Company (subject to the next succeeding sentence) shall
execute, and upon its written request the Trustee (subject as aforesaid) shall
authenticate and make available for delivery, a new

                                     15

<PAGE>

Debenture of the same series bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Debenture, or in
lieu of and in substitution for the Debenture so destroyed, lost or stolen.
In every case the applicant for a substituted Debenture shall furnish to the
Company and to the Trustee such security or indemnity as may be required by
them to save each of them harmless, and, in every case of destruction, loss
or theft, the applicant shall also furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft of  the
applicant's Debenture and of the ownership thereof. The Trustee may
authenticate any such substituted Debenture and make available for delivery
the same upon the written request or authorization of any officer of the
Company. Upon the issuance of any substituted Debenture, the Company may
require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected
therewith. In case any Debenture which has matured or is about to mature
shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Debenture, pay or authorize the payment of
the same (without surrender thereof except in the case of a mutilated
Debenture) if the applicant for such payment shall furnish to the Company and
to the Trustee such security or indemnity as they may require to save them
harmless, and, in case of destruction, loss or theft, evidence to the
satisfaction of the Company and the Trustee of the destruction, loss or theft
of such Debenture and of the ownership thereof.

  Every Debenture issued pursuant to the provisions of this Section in
substitution for any Debenture which is mutilated, destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the mutilated, destroyed, lost or stolen Debenture shall be found at any
time, or be enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Debentures of
the same series duly issued hereunder. All Debentures shall be held and owned
upon the express condition that the foregoing provisions are exclusive with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
Debentures, and shall preclude (to the extent lawful) any and all other rights
or remedies, notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.


  SECTION 2.08.  CANCELLATION OF SURRENDERED DEBENTURES.  All Debentures
surrendered for the purpose of payment, redemption, exchange or registration of
transfer shall, if surrendered to the Company or any paying agent, be delivered
to the Trustee for cancellation, or, if surrendered to the Trustee, shall be
cancelled by it, and no Debentures shall be issued in lieu thereof except as
expressly required or permitted by any of the provisions of this Indenture. On
written request of  the Company, the Trustee shall deliver to the Company
cancelled Debentures held by the Trustee. If the Company shall otherwise acquire
any of the Debentures, however, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Debentures
unless and until the same are delivered to the Trustee for cancellation.

                                     16

<PAGE>

  SECTION 2.09.  PROVISIONS OF INDENTURE AND DEBENTURES FOR SOLE BENEFIT OF
PARTIES AND DEBENTUREHOLDERS.  Nothing in this Indenture or in the Debentures,
express or implied, shall give or be construed to give to any Person, other than
the parties hereto and the holders of the Debentures, any legal or equitable
right, remedy or claim under or in respect of this Indenture, or under any
covenant, condition or provision herein contained; all such covenants,
conditions and provisions being for the sole benefit of the parties hereto and
of the holders of the Debentures.


  SECTION 2.10.  APPOINTMENT OF AUTHENTICATING AGENT.  So long as any of the
Debentures of any series remain outstanding there may be an Authenticating Agent
for any or all such series of Debentures which the Trustee shall have the right
to appoint.  Said Authenticating Agent shall be authorized to act on behalf of
the Trustee to authenticate Debentures of such series issued upon exchange,
transfer or partial redemption thereof, and Debentures so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder.  All references in
this Indenture to the authentication of Debentures by the Trustee shall be
deemed to include authentication by an Authenticating Agent for such series
except for authentication upon original issuance or pursuant to Section 2.07
hereof.  Each Authenticating Agent shall be acceptable to the Company and shall
be a corporation which has a combined capital and surplus, as most recently
reported or determined by it, sufficient under the laws of any jurisdiction
under which it is organized or in which it is doing business to conduct a trust
business, and which is otherwise authorized under such laws to conduct such
business and is subject to supervision or examination by Federal or State
authorities.  If at any time any Authenticating Agent shall cease to be eligible
in accordance with these provisions, it shall resign immediately.

  Any Authenticating Agent may at any time resign by giving written notice of
resignation to the Trustee and to the Company.  The Trustee may at any time (and
upon request by the Company shall) terminate the agency of any Authenticating
Agent by giving written notice of termination to such Authenticating Agent and
to the Company.  Upon resignation, termination or cessation of eligibility of
any Authenticating Agent, the Trustee may appoint an eligible successor
Authenticating Agent acceptable to the Company.  Any successor Authenticating
Agent, upon acceptance of its appointment hereunder, shall become vested with
all the rights, powers and duties of its predecessor hereunder as if originally
named as an Authenticating Agent pursuant hereto.


  SECTION 2.11.  GLOBAL DEBENTURES.  (a)  If the Company shall establish
pursuant to Section 2.01 that the Debentures of a particular series are to be
issued as one or more Global Debentures, then the Company shall execute and the
Trustee shall, in accordance with Section 2.04, authenticate and deliver, one or
more Global Debentures which (i) shall represent, and shall be denominated in an
aggregate amount equal to the aggregate principal amount of, all of the
Outstanding Debentures of such series, (ii) shall be registered in the name of
the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear,
subject to Section

                                     17

<PAGE>

2.01(12), a legend substantially to the following effect: "Except as
otherwise provided in Section 2.11 of the Indenture, this Debenture may be
transferred, in whole but not in part, only to another nominee of the
Depositary or to a successor Depositary or to a nominee of such successor
Depositary."

  (b)  Notwithstanding the provisions of Section 2.05, the Global Debenture
of a series may be transferred, in whole but not in part and in the manner
provided in Section 2.05, only to another nominee of the Depositary for such
series, or to a successor Depositary for such series selected or approved by the
Company or to a nominee of such successor Depositary.

  (c)  If at any time the Depositary for a series of Debentures notifies the
Company that it is unwilling or unable to continue as Depositary for such series
or if at any time the Depositary for such series shall no longer be registered
or in good standing under the Exchange Act, or other applicable statute or
regulation and a successor Depositary for such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such condition, as the case may be, this Section 2.11 shall no longer be
applicable to the Debentures of such series and the Company will execute, and
subject to Section 2.05, the Trustee will authenticate and make available for
delivery Debentures of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Debentures of such series in exchange for
such Global Debentures.  In addition, the Company may at any time determine that
the Debentures of any series shall no longer be represented by one or more
Global Debentures and that the provisions of this Section 2.11 shall no longer
apply to the Debentures of such series.  In such event the Company will execute
and subject to Section 2.05, the Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Company, will authenticate and
deliver Debentures of such series in definitive registered form without coupons,
in authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Debentures of such series in exchange for such
Global Debentures.  Upon the exchange of the Global Debentures for such
Debentures in definitive registered form without coupons, in authorized
denominations, the Global Debentures shall be cancelled by the Trustee.  Such
Debentures in definitive registered form issued in exchange for the Global
Debentures pursuant to this Section 2.11(c) shall be registered in such names
and in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee.  The Trustee shall deliver such Debentures to the Depositary for
delivery to the persons in whose name such Debentures are so registered.

  (d) Debentures distributed to holders of Global Certificates (as defined in
the applicable Declaration of Trust) upon the dissolution of the applicable
Trust shall be distributed in the form of one or more Global Debentures
registered in the name of the Depositary or its nominee, and deposited with the
Debenture Registrar, as custodian for the Depositary, or with such Depositary,
for credit by the Depositary to the respective accounts of the beneficial owners
of the Debentures represented thereby (or such other accounts as they may
direct).  Prior to the distribution of Debentures to holders of Global
Certificates

                                     18

<PAGE>

upon the dissolution of the applicable Trust, the Company shall designate the
Depositary in writing to the Trustee.  Debentures distributed to holders of
Certificates (as defined in the applicable Declaration of Trust), other than
Global Certificates, upon the dissolution of the applicable Trust shall not
be issued in the form of a Global Debenture or any other form intended to
facilitate book-entry trading in beneficial interests in such Debentures.

  (e) The Depositary or its nominee, as the registered owner of a Global
Debenture, shall be the holder of such Global Debenture for all purposes under
this Indenture and the Debentures, and owners of beneficial interests in a
Global Debenture shall hold such interests pursuant to the applicable procedures
of the Depositary.  Accordingly, any such owner's beneficial interest in a
Global Debenture shall be shown only on, and the transfer of such interest shall
be effected only through, records maintained by the Depositary or its nominee or
its participants.  None of the Company, the Trustee or the Debenture Registrar
shall have any liability in respect of any transfer effected by the Depositary.

  (f) The rights of owners of beneficial interests in a Global Debenture
shall be exercised only through the Depositary and shall be limited to those
established by law and agreements between such owners and the Depositary and/or
its participants.


  SECTION 2.12.  CUSIP NUMBERS.  The Company in issuing the Debentures may
use "CUSIP" numbers, and the Trustee shall use such CUSIP numbers in notices of
redemption or exchange as a convenience to Debentureholders and no
representation shall be made as to the correctness of such numbers either as
printed on the Debentures or as contained in any notice of redemption or
exchange.

                                 ARTICLE 3

          REDEMPTION OF DEBENTURES AND SINKING FUND PROVISIONS


  SECTION 3.01.  REDEMPTION.  The Company may redeem the Debentures of any
series issued hereunder on and after the dates and in accordance with the terms
established for such series pursuant to Section 2.01 hereof.


  SECTION 3.02.  NOTICE OF REDEMPTION.  (a)  In case the Company shall desire
to exercise such right to redeem all or, as the case may be, a portion of the
Debentures of any series in accordance with the right reserved so to do, it
shall give notice of such redemption to the Trustee at least 45 days in advance
of the date fixed for redemption.  The Trustee shall then notify holders of the
Debentures of such series who are to be redeemed by mailing, first class postage
prepaid, by a notice of such redemption not less than 30 days and not more than
60 days before the date fixed for redemption of that series to such holders at
their last addresses as they shall appear upon the Debenture Register.  Any
notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the registered holder receives
the notice.  In any case, failure duly to give such notice

                                     19

<PAGE>

to the holder of any Debenture of any series designated for redemption in
whole or in part, or any defect in the notice, shall not affect the validity
of the proceedings for the redemption of any other Debentures of such series
or any other series.  In the case of any redemption of Debentures prior to
the expiration of any restriction on such redemption provided in the terms of
such Debentures or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with any such
restriction.

  Each such notice of redemption shall identify the Debentures to be redeemed
(including CUSIP number) and shall specify:(i) the date fixed for
redemption,(ii) the redemption price at which Debentures of that series are to
be redeemed,(iii) the place or places where Debentures are to be surrendered for
payment of the redemption price,(iv) that payment of the redemption price will
be made upon presentation and surrender of such Debentures at such place or
places,(v) that interest accrued to the date fixed for redemption will be paid
as specified in said notice,(vi) that from and after said date interest will
cease to accrue and (vii) that the redemption is for a sinking fund, if such is
the case.  If less than all the Debentures of a series are to be redeemed, the
notice to the holders of Debentures of that series to be redeemed in whole or in
part shall specify the particular Debentures to be so redeemed.  In case any
Debenture is to be redeemed in part only, the notice which relates to such
Debenture shall state the portion of the principal amount thereof to be
redeemed, and shall state that on and after the redemption date, upon surrender
of such Debenture, a new Debenture or Debentures of such series in principal
amount equal to the unredeemed portion thereof will be issued.

  (b) In the event of a partial redemption of a series of Debentures, the
Company shall give the Trustee at least 45 days' notice in advance of the date
fixed for redemption as to the aggregate principal amount of Debentures of the
series to be redeemed and the other information set forth in the immediately
preceding paragraph, and thereupon the Trustee shall select, by lot or in such
other manner as it shall deem appropriate and fair in its discretion and which
may provide for the selection of a portion or portions (equal to $25 or any
integral multiple thereof) of the principal amount of such Debentures of a
denomination larger than $25, the Debentures to be redeemed and shall thereafter
promptly notify the Company in writing of the numbers of the Debentures to be
redeemed, in whole or in part.  For all purposes of this Indenture, unless the
context otherwise requires, all provisions relating to the redemption of
Debentures shall relate, in the case of any Debenture redeemed or to be redeemed
only in part, to the portion of the principal amount of such Debenture which has
been or is to be redeemed. If the Company shall so direct, Debentures registered
in the name of the Company, any Affiliate or any Subsidiary thereof shall not be
included in the Debentures selected for redemption.

  The Company may, if and whenever it shall so elect, by delivery of
instructions signed on its behalf by its President or any Vice President,
instruct the Trustee or any paying agent to call all or any part of the
Debentures of a particular series for redemption and to give notice of
redemption in the manner set forth in this Section, such notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable.  In

                                     20

<PAGE>

any case in which notice of redemption is to be given by the Trustee or any
such paying agent, the Company shall deliver or cause to be delivered to, or
permit to remain with, the Trustee or such paying agent, as the case may be,
such Debenture Register, transfer books or other records, or suitable copies
or extracts therefrom, sufficient to enable the Trustee or such paying agent
to give any notice by mail that may be required under the provisions of this
Section.

  SECTION 3.03.  PAYMENT UPON REDEMPTION.  (a)  If the giving of notice of
redemption shall have been completed as above provided and funds deposited as
required, the Debentures or portions of Debentures of the series to be redeemed
specified in such notice shall become due and payable on the date and at the
place stated in such notice at the applicable redemption price, together with
interest accrued to, but excluding,  the date fixed for redemption, and interest
on such Debentures or portions of Debentures shall cease to accrue on and after
the date fixed for redemption, unless the Company shall default in the payment
of such redemption price and accrued interest with respect to any such Debenture
or portion thereof.  On presentation and surrender of such Debentures on or
after the date fixed for redemption at the place of payment specified in the
notice, said Debentures shall be paid and redeemed at the applicable redemption
price for such series, together with interest accrued thereon to, but excluding,
the date fixed for redemption (but if the date fixed for redemption is an
interest payment date, the interest installment payable on such date shall be
payable to the registered holder at the close of business on the applicable
record date pursuant to Section 2.03).

  (b)  Upon presentation of any Debenture of such series which is to be
redeemed in part only, the Company shall execute and the Trustee shall
authenticate and the office or agency where the Debenture is presented shall
make available for delivery to the holder thereof, at the expense of the
Company, a new Debenture or Debentures of the same series, of authorized
denominations in principal amount equal to the unredeemed portion of the
Debenture so presented.


  SECTION 3.04.  SINKING FUNDS FOR DEBENTURES.  The provisions of Sections
3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the retirement
of Debentures of a series, except as otherwise specified as contemplated by
Section 2.01 for Debentures of such series.

  The minimum amount of any sinking fund payment provided for by the terms of
Debentures of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Debentures of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Debentures for any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 3.05. Each sinking fund payment shall be applied to the redemption of
Debentures of any series as provided for by the terms of Debentures of such
series.

                                     21

<PAGE>

  SECTION 3.05.  SATISFACTION OF SINKING FUND PAYMENTS WITH DEBENTURES.  The
Company (i) may deliver outstanding Debentures of a series (other than any
previously called for redemption) and (ii) may apply as a credit Debentures of a
series which have been redeemed either at the election of the Company pursuant
to the terms of such Debentures or through the application of permitted optional
sinking fund payments pursuant to the terms of such Debentures, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Debentures of such series required to be made pursuant to the terms of such
Debentures as provided for by the terms of such series; provided that such
Debentures have not been previously so credited. Such Debentures shall be
received and credited for such purpose by the Trustee at the redemption price
specified in such Debentures for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.


  SECTION 3.06.  REDEMPTION OF DEBENTURES FOR SINKING FUND.  Not less than 45
days prior to each sinking fund payment date for any series of Debentures, the
Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing sinking fund payment for that series pursuant to the
terms for that series, the portion thereof, if any, which is to be satisfied by
delivering and crediting Debentures of that series pursuant to Section 3.05 and
the basis for such credit and will, together with such Officers' Certificate,
deliver to the Trustee any Debentures to be so delivered. Not less than 30 days
before each such sinking fund payment date the Trustee shall select the
Debentures to be redeemed upon such sinking fund payment date in the manner
specified in Section 3.02 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 3.02. Such notice having been duly given, the redemption of such
Debentures shall be made upon the terms and in the manner stated in Section
3.03.

                                ARTICLE 4

                   PARTICULAR COVENANTS OF THE COMPANY

  The Company covenants and agrees for each series of the Debentures as
follows:


  SECTION 4.01.  PAYMENT OF PRINCIPAL OF (AND PREMIUM, IF ANY) AND INTEREST
ON DEBENTURES.   The Company will duly and punctually pay or cause to be paid
the principal of (and premium, if any) and interest on the Debentures of that

with respect to such Debentures.


  SECTION 4.02.  MAINTENANCE OF OFFICE OR AGENT FOR PAYMENT OF DEBENTURES,
DESIGNATION OF OFFICE OR AGENCY FOR PAYMENT, REGISTRATION, TRANSFER AND EXCHANGE
OF DEBENTURES.  So long as any series of the Debentures remain outstanding, the
Company agrees to maintain an office or agency in each Place of Payment, with
respect to each such series and at such other location or locations as may be
designated as provided in this Section 4.02, where (i) Debentures of that series
may be presented for payment, (ii) Debentures of

                                     22

<PAGE>

that series may be presented as hereinabove authorized for registration of
transfer and exchange, and (iii) notices and demands to or upon the Company
in respect of the Debentures of that series and this Indenture may be given
or served, such designation to continue with respect to such office or agency
until the Company shall, by written notice signed by its President or a Vice
President and delivered to the Trustee, designate some other office or agency
for such purposes or any of them. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, notices and demands may
be made or served at the Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, notices and demands.

  SECTION 4.03.  DUTIES OF PAYING AGENT; COMPANY AS PAYMENT AGENT; AND
HOLDING SUMS IN TRUST.  (a)  If the Company shall appoint one or more paying
agents for all or any series of the Debentures, other than the Trustee, the
Company will cause each such paying agency to execute and deliver to the Trustee
an instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section:

            (1)  that it will hold all sums held by it as such agent for the
            payment of the principal of (and premium, if any) or interest on
            the Debentures of that series (whether such sums have been paid
            to it by the Company or by any other obligor of such Debentures)
            in trust for the benefit of the persons entitled thereto:

            (2)  that it will give the Trustee written notice of any failure
            by the Company (or by any other obligor of such Debentures) to
            make any payment of the principal of (and premium, if any) or
            interest on the Debentures of that series when the same shall be
            due and payable;

            (3)  that it will, at any time during the continuance of any
            failure referred to in the preceding paragraph (a)(2) above, upon
            the written request of the Trustee, forthwith pay to the Trustee
            all sums so held in trust by such paying agent; and

            (4)  that it will perform all other duties of paying agent as set
            forth in this Indenture.

  (b)  If the Company shall act as its own paying agent with respect to any
series of the Debentures, it will on or before each due date of the principal of
(and premium, if any) or interest on Debentures of that series, set aside,
segregate and hold in trust for the benefit of the persons entitled thereto a
sum sufficient to pay such principal (and premium, if any) or interest so
becoming due on Debentures of that series until such sums shall be paid to such
persons or otherwise disposed of as herein provided and will promptly notify in
writing the Trustee of such action, or any failure (by it or any other obligor
on such Debentures) to take such action. Whenever the Company shall have one or
more paying agents for any series of

                                     23

<PAGE>

Debentures, it will, prior to 11:00 a.m., New York City time on each due date
of the principal of (and premium, if any) or interest on any Debentures of
that series, deposit with the paying agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the persons entitled to such principal,
premium or interest, and (unless such paying agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

  (c)  Anything in this Section to the contrary notwithstanding, (i) the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Section 11.05, and (ii) the Company may at any time, for the
purpose of obtaining the satisfaction and discharge of this Indenture or for any
other purpose, pay, or direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying agent, such sums to be held by the
Trustee upon the same terms and conditions as those upon which such sums were
held by the Company or such paying agent; and, upon such payment by any paying
agent to the Trustee, such paying agent shall be released from all further
liability with respect to such money.


  SECTION 4.04.  APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.  The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

                                   ARTICLE 5

       DEBENTUREHOLDERS LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE


  SECTION 5.01.  COMPANY TO FURNISH TRUSTEE INFORMATION AS TO NAMES AND
ADDRESSES OF DEBENTUREHOLDERS.  The Company will furnish or cause to be
furnished to the Trustee (a) on each regular record date (as defined in Section
2.03) a list, in such form as the Trustee may reasonably require, of the  names
and addresses of the holders of each series of Debentures as of such regular
record date, provided, that the Company shall not be obligated to furnish or
cause to be furnished such list at any time that the list shall not differ in
any respect from the most recent list furnished to the Trustee by the Company
and (b) at such other times as the Trustee may request in writing within 30 days
after the receipt by the Company of any such request, a list of similar form and
content as of a date not more than 15 days prior to the time such list is
furnished; provided, however, no such list need be furnished for any series for
which the Trustee shall be the Debenture Registrar.


  SECTION 5.02.  TRUSTEE TO PRESERVE INFORMATION AS TO NAMES AND ADDRESSES OF
DEBENTUREHOLDERS.  (a)  The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Debentures contained in the most recent list furnished to it as
provided in Section 5.01 and as to the names and addresses of holders of
Debentures received by the Trustee in its capacity as Debenture Registrar (if
acting in such capacity).

                                     24
<PAGE>


  (b)  The Trustee may destroy any list furnished to it as provided in
Section 5.01 upon receipt of a new list so furnished.

  (c)  In case three or more holders of Debentures of a series (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a Debenture for a
period of at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other holders
of Debentures of such series or holders of all Debentures with respect to their
rights under this Indenture or under such Debentures, and is accompanied by a
copy of the form of proxy or other communication which such applicants propose
to transmit, then the Trustee shall within five Business Days after the receipt
of such application, at its election, either:

       (1)  afford to such applicants access to the information preserved at
       the time by the Trustee in accordance with the provisions of
       subsection (a) of this Section 5.02; or

       (2)  inform such applicants as to the approximate number of holders of
       Debentures of such series or of all Debentures, as the case may be,
       whose names and addresses appear in the information preserved at the
       time by the Trustee, in accordance with the provisions of subsection
       (a) of this Section 5.02, and as to the approximate cost of mailing to
       such Debentureholders the form of proxy or other communication, if
       any, specified in such application.

  (d)  If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each holder of such series or of all Debentures, as the case
may be, whose name and address appears in the information preserved at the time
by the Trustee in accordance with the provisions of subsection (a) of this
Section 5.02, a copy of the form of proxy or other communication which is
specified in such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of mailing, unless within five days after
such tender, the Trustee shall mail to such applicants and file with the
Securities and Exchange Commission (the "Commission"), together with a copy of
the material to be mailed, a written statement to the effect that, in the
opinion of the Trustee, such mailing would be contrary to the best interests of
the holders of Debentures of such series or of all Debentures, as the case may
be, or would be in violation of applicable law. Such written statement shall
specify the basis of such opinion.  If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Debentureholders with reasonable
promptness after the entry of such order and the renewal of


                                    25
<PAGE>


such tender; otherwise, the Trustee shall be relieved of any obligation or
duty to such applicants respecting their application.

  (e)  Each and every holder of the Debentures, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee nor any paying agent nor any Debenture Registrar shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the holders of Debentures in accordance with the provisions of
subsection (c) of this Section 5.02, regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under said subsection
(c).


  SECTION 5.03.  ANNUAL AND OTHER REPORTS TO BE FILED BY COMPANY WITH THE
TRUSTEE.  (a)  The Company covenants and agrees to file with the Trustee, within
15 days after the Company is required to file the same with the Commission,
copies of the annual reports and of the information, documents and other reports
(or copies of such portions of any of the foregoing as the Commission may from
time to time by rules and regulations prescribe) which the Company may be
required to file with the Commission pursuant to Section 13 or Section 15(d) of
the Exchange Act; or, if the Company is not required to file information,
documents or reports pursuant to either of such sections, then to file with the
Trustee and the Commission in accordance with the rules and regulations
prescribed from time to time by the Commission, such of the supplementary and
periodic information, documents and reports which may be required pursuant to
Section 13 of the Exchange Act, in respect of a security listed and registered
on a national securities exchange as  may be prescribed from time to time in
such rules and regulations.  Delivery of such reports, information and documents
to the Trustee is for informational purposes only and the Trustee's receipt of
such shall not constitute constructive notice of any information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

    REMEDIES OF THE TRUSTEE AND DEBENTUREHOLDERS ON EVENT OF DEFAULT

  SECTION 6.01.  EVENTS OF DEFAULT DEFINED.  (a) Whenever used herein with
respect to Debentures of a particular series, "Event of Default" means any one
or more of the following events which has occurred and is continuing:

       (1) default in the payment of any installment of interest upon any of
       the Debentures of that series, as and when the same shall become due
       and payable, and continuance of such default for a period of 90 days;
       provided, however, that a valid extension of an interest payment
       period by the Company, in accordance with the terms of Debentures of
       that series established pursuant to Section 2.01 hereof, shall not
       constitute a default in the payment of interest for this purpose;

       (2) default (i) in the payment of the principal of (and premium, if
       any, on) any of the Debentures of that series as and when the same
       shall become due and payable whether at maturity, upon redemption, by
       declaring or otherwise, or (ii) in any payment required by any sinking
       or analogous fund established


                                    27
<PAGE>


       with respect to that series, and in the case of this clause (ii) only,
       continuance of such default for a period of 90 days;

       (3) failure on the part of the Company duly to observe or perform, in
       any material respect, any other of the covenants or agreements on the
       part of the Company with respect to that series contained in such
       Debentures or otherwise established with respect to that series of
       Debentures pursuant to Section 2.01 hereof or contained in this
       Indenture (other than a covenant or agreement which has been expressly
       included in this Indenture solely for the benefit of one or more
       series of Debentures other than such series) for a period of 90 days
       after the date on which written notice of such failure, requiring the
       same to be remedied and stating that such notice is a "Notice of
       Default" hereunder, shall have been given to the Company by the
       Trustee, by registered or certified mail, or to the Company and the
       Trustee by the holders of at least 25% in principal amount of the
       Debentures of that series at the time Outstanding;

       (4) a decree or order by a court having jurisdiction in the premises
       shall have been entered adjudging the Company as bankrupt or
       insolvent, or approving as properly filed  a petition seeking
       liquidation or reorganization of the Company under the Federal
       Bankruptcy Code or any other similar applicable Federal or State law,
       and such decree or order shall have continued unvacated and unstayed
       for a period of 90 days; or an involuntary case shall be commenced
       under such Code in respect of the Company and shall continue
       undismissed for a period of 90 days or an order for relief in such
       case shall have been entered; or a decree or order of a court having
       jurisdiction in the premises shall have been entered for the
       appointment on the ground of insolvency or bankruptcy of a receiver or
       custodian or liquidator or trustee or assignee in bankruptcy or
       insolvency of the Company or of its property, or for the winding up or
       liquidation of its affairs, and such decree or order shall have
       remained in force unvacated and unstayed for a period of 90 days;

       (5) the Company shall institute proceedings to be adjudicated a
       voluntary bankrupt, or shall consent to the filing of a bankruptcy
       proceeding against it, or shall file a petition or answer or consent
       seeking liquidation or reorganization under the Federal Bankruptcy
       Code or any other similar applicable Federal or State law, or shall
       consent to the filing of any such petition, or shall consent to the
       appointment on the ground of insolvency or bankruptcy of a receiver or
       custodian or liquidator or trustee or assignee in bankruptcy or
       insolvency of it or of its property, or shall make an assignment for
       the benefit of creditors; or

       (6) any other Event of Default provided with respect to Debentures of
       that series.


                                      28
<PAGE>


  (b)  In each and every such case, unless the principal of all the
Debentures of that series shall have already become due and payable, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the
Debentures of that series then Outstanding hereunder, by notice in writing to
the Company (and to the Trustee if given by such Debentureholders), may declare
the principal of all the Debentures of that series to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, anything contained in this Indenture or in the
Debentures of that series or established with respect to that series pursuant to
Section 2.01 to the contrary notwithstanding.  Payment of principal and interest
on such Debentures shall remain subordinated to the extent provided in Article
14 notwithstanding that such amount shall become immediately due and payable as
herein provided.


  (c)  SECTION 6.01(b), however, is subject to the condition that if, at any
time after the principal of the Debentures of that series shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, the
Company shall pay or shall deposit with the Trustee a sum sufficient to pay all
matured installments of interest upon all the Debentures of that series and the
principal of (and premium, if any, on) any and all Debentures of that series
which shall have become due otherwise than by acceleration (with interest upon
such principal and premium, if any, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum expressed in the Debentures of that series to the date of such
payment or deposit) and the amount payable to the Trustee under Section 7.06,
and any and all defaults under the Indenture, other than the nonpayment of
principal on Debentures of that series which shall not have become due by their
terms, shall have been remedied or waived as provided in Section 6.06 then and
in every such case the holders of a majority in aggregate principal amount of
the Debentures of that series then outstanding (subject to, in the case of any
series of Debentures held as trust assets of a Trust and with respect to which a
Security Exchange has not theretofore occurred, such consent of the holders of
the Preferred Securities and the Common Securities of such Trust as may be
required under the Declaration of Trust of such Trust), by written notice to the
Company and to the Trustee, may rescind and annul such declaration and its
consequences with respect to that series of Debentures; but no such rescission
and annulment shall extend to or shall affect any subsequent default, or shall
impair any right consequent thereon.


  (d)    In case the Trustee shall have proceeded to enforce any right with
respect to Debentures of that series under this Indenture and such
proceedings shall have been discontinued or abandoned because of such
rescission or annulment or for any other reason or shall have been determined
adversely to the Trustee, then and in every such case the Company and the
Trustee shall be restored respectively to their former positions and rights
hereunder, and all rights, remedies and powers of the Company and the Trustee
shall continue as though no such proceedings had been taken.

  (e)  If, prior to a Security Exchange with respect to the Debentures of any
series, a Default with respect to the Debentures of such series shall have
occurred, the Company


                                 29
<PAGE>


expressly acknowledges that under the circumstances set forth in the
applicable Declaration of Trust, any holder of Preferred Securities of the
applicable Trust may, to the fullest extent permitted by law, enforce
directly against the Company the applicable Property Trustee's rights
hereunder. In furtherance of the foregoing and for the avoidance of any
doubt, the Company acknowledges that, under the circumstances described in
the applicable Declaration of Trust, any such holder of Preferred Securities,
in its own name, in the name of the applicable Trust or in the name of the
holders of the Preferred Securities issued by such Trust, may institute or
cause to be instituted a proceeding, including, without limitation, any suit
in equity, an action at law or other judicial or administrative proceeding,
to enforce the applicable Property Trustee's rights hereunder directly
against the Company as issuer of the applicable series of Debentures, and may
prosecute such proceeding to judgment or final decree, and enforce the same
against the Company.

  SECTION 6.02.  COVENANT OF COMPANY TO PAY TO TRUSTEE WHOLE AMOUNT DUE ON
DEBENTURES ON DEFAULT IN PAYMENT OF INTEREST OR PRINCIPAL (AND PREMIUMS, IF
ANY).  (a) The Company covenants that (1) in case default shall be made in
(A) the payment of any installment of interest on any of the Debentures of a
series and such default shall have continued for a period of 30 days, or (B)
any payment required by any sinking or analogous fund established with
respect to that series as and when the same shall have become due and
payable, and such default shall have continued for a period of 90 days, or
(2) in case default shall be made in the payment of the principal of (or
premium, if any, on) any of the Debentures of a series when the same shall
have become due and payable, whether upon maturity of the Debentures of a
series or upon redemption or upon declaration or otherwise, then, upon demand
of the Trustee, the Company will pay to the Trustee, for the benefit of the
holders of the Debentures of that series, the whole amount that then shall
have become due and payable on all such Debentures for principal (and
premium, if any) or interest, or both, as the case may be, with interest upon
the overdue principal (and premium, if any) and (to the extent that payment
of such interest is enforceable under applicable law and without duplication
of any other amounts paid by the Company or the applicable Trust in respect
thereof) upon overdue installments of interest at the rate per annum
expressed in the Debentures of that series; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, and the amount payable to the Trustee under Section 7.06.

  (b)  In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the
Debentures of that series and collect in the manner provided by law out of the
property of the Company or other obligor upon the Debentures of that series
wherever situated the moneys adjudged or decreed to be payable.

  (c)  In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or other judicial
proceedings affecting the Company,


                                30
<PAGE>


any other obligor on such Debentures, or the creditors or property of either,
the Trustee shall have the power to intervene in such proceedings and take
any action therein that may be permitted by the court and shall (except as
may be otherwise provided by law) be entitled to file such proofs of claim
and other papers and documents as may be necessary or advisable in order to
have the claims of the Trustee and of the holders of Debentures of such
series allowed for the entire amount due and payable by the Company or such
other obligor under the Indenture at the date of institution of such
proceedings and for any additional amount which may become due and payable by
the Company or such other obligor after such date, and to collect and receive
any moneys or other property payable or deliverable on any such claim, and to
distribute the same after the deduction of the amount payable to the Trustee
under Section 7.06; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the holders of Debentures of
such series to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to such
Debentureholders, to pay to the Trustee any amount due it under Section 7.06.

  (d)  All rights of action and of asserting claims under this Indenture, or
under any of the terms established with respect to Debentures of that series,
may be enforced by the Trustee without the possession of any of such Debentures,
or the production thereof at any trial or other proceeding relative thereto, and
any such suit or proceeding instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment shall,
after provision for payment to the Trustee of any amounts due under Section
7.06, be for the ratable benefit of the holders of the Debentures of such
series.

  In case of an Event of Default hereunder, the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any of such rights, either at law or in equity or in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

  Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Debentureholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Debentures of that series or the rights of any holder thereof or to authorize
the Trustee to vote in respect of the claim of any Debentureholder in any such
proceeding.

  SECTION 6.03.  APPLICATION OF MONEYS COLLECTED BY TRUSTEE.  Any moneys
collected by the Trustee pursuant to this Article with respect to a particular
series of Debentures shall be applied in the order following, at the date or
dates fixed by the Trustee and, in case of the distribution of such moneys on
account of principal (or premium, if any) or interest, upon presentation of the
several Debentures of that series, and stamping thereon the payment, if only
partially paid, and upon surrender thereof if fully paid:


                                   31
<PAGE>


    FIRST:  To the payment of costs and expenses of collection and of all
    amounts payable to the Trustee under Section 7.06;

    SECOND:  To the payment of all Senior Debt of the Company if and to the
    extent required by Article 14;

    THIRD:  To the payment of the amounts then due and unpaid upon Debentures
    of such series for principal (and premium, if any) and interest, in respect
    of which or for the benefit of which such money has been collected,
    ratably, without preference or priority of any kind, according to the
    amounts due and payable on such Debentures for principal (and premium, if
    any) and interest, respectively; and

    FOURTH: The balance, if any, to the Person or Persons entitled thereto.

  SECTION 6.04.  LIMITATION ON SUITS BY HOLDERS OF DEBENTURES.  No holder of
any Debenture of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Indenture or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
(i) such holder previously shall have given to the Trustee written notice of an
Event of Default and of the continuance thereof with respect to Debentures of
such series specifying such Event of Default, as hereinbefore provided,(ii) the
holders of not less than 25% in aggregate principal amount of the Debentures of
such series then outstanding shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as trustee
hereunder,(iii) shall have offered to the Trustee indemnity satisfactory to it
against the costs, expenses and liabilities to be incurred therein or
thereby,(iv) the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity, shall have failed to institute any such action, suit or
proceeding and (v) during such 60 day period, the holders of a majority in
principal amount of the Debentures of that series do not give the Trustee a
direction inconsistent with the request; it being understood and intended, and
being expressly covenanted by the taker and holder of every Debenture of such
series with every other such taker and holder and Trustee, that no one or more
holders of Debentures of such series shall have any right in any manner
whatsoever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of the holders of any other of such
Debentures, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Debentures of such series.  For the protection and enforcement of the
provisions of this Section, each and every Debentureholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

  Notwithstanding any other provisions of this Indenture, however, the right
of any holder of any Debenture to receive payment of the principal of (and
premium, if any) and interest on such Debenture, as therein provided, on or
after the respective due dates expressed


                                    32
<PAGE>


in such Debenture (or in the case of redemption, on the redemption date), or
to institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected
without the consent of such holder.

  SECTION 6.05.  REMEDIES CUMULATIVE; DELAY OR OMISSION IN EXERCISE OF RIGHTS
NOT WAIVER OF DEFAULT.

  (a)  All powers and remedies given by this Article 6 to the Trustee or to
the Debentureholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any others thereof or of any other powers and remedies
available to the Trustee or the holders of the Debentures, by judicial
proceedings or otherwise, to enforce performance or observance of the covenants
and agreements contained in this Indenture or otherwise established with respect
to such Debentures.

  (b)  No delay or omission of the Trustee or of any holder of any of the
Debentures to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 6.04, every power and remedy
given by this Article or by law to the Trustee or to the Debentureholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Debentureholders.

  SECTION 6.06.  RIGHTS OF HOLDERS OF MAJORITY IN PRINCIPAL AMOUNT OF
DEBENTURES TO DIRECT TRUSTEE AND TO WAIVE DEFAULTS.  The holders of a majority
in aggregate principal amount of the Debentures of any series at the time
Outstanding, determined in accordance with Section 8.04 (with, in the case of
any series of Debentures held as trust assets of a Trust and with respect to
which a Security Exchange has not theretofore occurred, such consent of holders
of the Preferred Securities and the Common Securities of such Trust as may be
required under the Declaration of Trust of such Trust), shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee with respect to such series; provided, however, that such direction
shall not be in conflict with any rule of law or with this Indenture or unduly
prejudicial to the rights of holders of Debentures of any other series at the
time Outstanding determined in accordance with Section 8.04 not parties thereto.
Subject to the provisions of Section 7.01, the Trustee shall have the right to
decline to follow any such direction if the Trustee in good faith shall, by a
Responsible Officer or Officers of the Trustee, determine that the proceeding so
directed would involve the Trustee in personal liability.  The holders of a
majority in aggregate principal amount of the Debentures of any series at the
time Outstanding affected thereby, determined in accordance with section 8.04
(with, in the case of any series of Debentures held as trust assets of a Trust
and with respect to which a Security Exchange has not theretofore occurred, such
consent of holders of the Preferred Securities and the Common Securities of such
Trust as may be required under the Declaration of Trust of such Trust), may on
behalf of the holders of all of the Debentures of such series waive any past
default in the performance of any of the covenants contained


                                    33
<PAGE>


herein or established pursuant to Section 2.01 with respect to such series
and its consequences, except a default in the payment of the principal of, or
premium, if any, or interest on, any of the Debentures of that series as and
when the same shall become due by the terms of such Debentures otherwise than
by acceleration (unless such default has been cured and a sum sufficient to
pay all matured installments of interest and principal and any premium has
been deposited with the Trustee (in accordance with Section 6.01(c)), or a
call for redemption of Debentures of that series.  Upon any such waiver, the
default covered thereby shall be deemed to be cured for all purposes of this
Indenture and the Company, the Trustee and the holders of the Debentures of
such series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

  SECTION 6.07.  TRUSTEE TO GIVE NOTICE OF DEFAULTS KNOWN TO IT, BUT MAY
WITHHOLD IN CERTAIN CIRCUMSTANCES.  The Trustee shall, within 90 days after the
occurrence of a default with respect to a particular series, transmit by mail,
first class postage prepaid, to the holders of Debentures of that series, as
their names and addresses appear upon the Debenture Register, notice of all
defaults with respect to that series known to the Trustee, unless such defaults
shall have been cured before the giving of such notice (the term "defaults" for
the purposes of this Section being hereby defined to be the events specified in
subsections (1), (2), (3), (4) and (5) of Section 6.01(a), not including any
periods of grace provided for therein and irrespective of the giving of notice
provided for by subsection (3) of Section 6.01(a)); 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 of that series or in the payment of any
sinking fund installment established with respect to that series, the 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 Trustee in good faith determine that the
withholding of such notice is in the interests of the holders of Debentures of
that series; provided further, that in the case of any default of the character
specified in Section 6.01(a)(3) with respect to Debentures of such series no
such notice to the holders of the Debentures of that series shall be given until
at least 30 days after the occurrence thereof.

  The Trustee shall not be deemed to have knowledge of any default, except
(i) a default under subsection (a)(1) or (a)(2) of Section 6.01 as long as the
Trustee is acting as paying agent for such series of Debentures or (ii) any
default as to which a Responsible Officer of the Trustee shall have received
written notice.

  SECTION 6.08.  REQUIREMENTS OF AN UNDERTAKING TO PAY COSTS IN CERTAIN SUITS
UNDER INDENTURE OR AGAINST TRUSTEE.  All parties to this Indenture agree, and
each holder of any Debentures by his or her acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
such suit, having due regard to the merits and


                                  34

<PAGE>

good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Debentureholder, or group of
Debentureholders, holding more than 10% in aggregate principal amount of the
outstanding Debentures of any series, or to any suit instituted by any
Debentureholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Debenture of such series, on or after the
respective due dates expressed in such Debenture or established pursuant to
this Indenture.

                           ARTICLE 7
                     Concerning the Trustee

  Section 7.01.  UPON EVENT OF DEFAULT OCCURRING AND CONTINUING, TRUSTEE
SHALL EXERCISE POWERS VESTED IN IT, AND USE SAME DEGREE OF CARE AND SKILL IN
THEIR EXERCISE, AS PRUDENT INDIVIDUAL WOULD USE.  (a)  The Trustee, prior to the
occurrence of an Event of Default with respect to Debentures of a series and
after the curing of all Events of Default with respect to Debentures of that
series which may have occurred, shall undertake to perform with respect to
Debentures of such series such duties and only such duties as are specifically
set forth in this Indenture, and no implied covenants shall be read into this
Indenture against the Trustee.  In case an Event of Default with respect to
Debentures of a series has occurred (which has not been cured or waived), the
Trustee shall exercise with respect to Debentures of that series such of the
rights and powers vested in it by this Indenture, 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 Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

       (1)  prior to the occurrence of an Event of Default with respect
       to Debentures of a series and after the curing or waiving of all
       such Events of Default with respect to that series which may have
       occurred:

            (i)  the duties and obligations of the Trustee shall with
            respect to Debentures of such series be determined solely by
            the express provisions of this Indenture and the Trust
            Indenture Act, and the Trustee shall not be liable with
            respect to Debentures of such series except for the
            performance of such duties and obligations as are
            specifically set forth in this Indenture, and no implied
            covenants or obligations shall be read into this Indenture
            against the Trustee; and

                                   35
<PAGE>

            (ii)  in the absence of bad faith on the part of the
            Trustee, the Trustee may with respect to Debentures of such
            series 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 Trustee and
            conforming to the requirements of this Indenture; but in the
            case of any such certificates or opinions which by any
            provision hereof are specifically required to be furnished
            to the Trustee, the Trustee shall be under a duty to examine
            the same to determine whether or not they conform to the
            requirements of this Indenture but need not confirm or
            investigate the accuracy of mathematical calculations or
            other facts stated therein;

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

       (3)  the 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 principal
       amount of the Debentures of any series at the time outstanding
       relating to the time, method and place of conducting any proceeding
       for any remedy available to the Trustee, or exercising any trust or
       power conferred upon the Trustee under this Indenture with respect to
       the Debentures of that series;

       (4)  none of the provisions contained in this Indenture shall require
       the 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 there is
       reasonable ground for believing that the repayment of such funds or
       liability is not reasonably assured to it under the terms of this
       Indenture or adequate indemnity against such risk is not reasonably
       assured to it; and

       (5)  whether or not therein expressly so provided, every provision of
       this Indenture relating to the conduct or affecting the liability of
       or affording protection to the Trustee shall be subject to the
       provisions of this Article 7.

    SECTION 7.02.  CERTAIN RIGHTS OF THE TRUSTEE.  Except as otherwise provided
in Section 7.01:

           (a)  The Trustee may conclusively rely and shall be protected in
       acting or refraining from acting upon any resolution, certificate,
       statement,

                                   36
<PAGE>

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

           (b)  Any request, direction, order or demand of the Company
       mentioned herein shall be sufficiently evidenced by a Board Resolution
       or an instrument signed in the name of the Company by the President or
       any Vice President and by the Secretary or an Assistant Secretary or
       the Treasurer or an Assistant Treasurer (unless other evidence in
       respect thereof is specifically prescribed herein);

           (c)  The Trustee may consult with counsel of its selection and the
       written advice of such counsel or any Opinion of Counsel shall be full
       and complete authorization and protection in respect of any action
       taken or suffered or omitted hereunder in good faith and in reliance
       thereon;

           (d)  The Trustee shall be under no obligation to exercise any of
       the rights or powers vested in it by this Indenture at the request,
       order or direction of any of the Debentureholders, pursuant to the
       provisions of this Indenture, unless such Debentureholders shall have
       offered to the Trustee security or indemnity satisfactory to it
       against the costs, expenses and liabilities which may be incurred
       therein or thereby; nothing herein contained shall, however, relieve
       the Trustee of the obligation, upon the occurrence of an Event of
       Default with respect to a series of the Debentures (which has not been
       cured or waived) to exercise with respect to Debentures of that series
       such of the rights and powers vested in it by this Indenture, and to
       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
       such person's own affairs;

           (e)  The Trustee shall not be liable for any action taken or
       omitted to be taken by it in good faith and believed by it to be
       authorized or within the discretion or rights or powers conferred upon
       it by this Indenture;

           (f)  The Trustee shall not be bound to make any investigation into
       the facts or matters stated in any resolution, certificate, statement,
       instrument, opinion, report, notice, request, consent, order,
       approval, bond, security, or other papers or documents, unless
       requested in writing so to do by the holders of not less than a
       majority in principal amount of the outstanding Debentures of the
       particular series affected thereby (determined as provided in Section
       8.04); PROVIDED, HOWEVER, that if the payment within a reasonable time
       to the Trustee of the costs, expenses or liabilities likely to be
       incurred by it in the making of such investigation is, in the opinion
       of the Trustee, not reasonably assured to the Trustee by the security
       afforded to it by the terms of this Indenture, the Trustee may require
       indemnity satisfactory to it against such

                                   37
<PAGE>



       costs, expenses or liabilities as a condition to so proceeding.  The
       reasonable expense of every such examination shall be paid by the Company
       or, if paid by the Trustee, shall be repaid by the Company upon demand;

           (g)  The 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 Trustee shall not be responsible for any
       misconduct or negligence on the part of any agent or attorney
       appointed with due care by it hereunder; and

           (h)  The rights, privileges, protections, immunities and benefits
       given to the Trustee, including, without limitation, its right to be
       indemnified, are extended to, and shall be enforceable by, the Trustee
       in each of its capacities hereunder, and to each agent, custodian and
       other Person employed to act hereunder.

    SECTION 7.03.  TRUSTEE NOT LIABLE FOR RECITALS IN INDENTURE OR IN
DEBENTURES.  (a) The recitals contained herein and in the Debentures (other
than the Certificate of Authentication on the Debentures) shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for
the correctness of the same.

    (b)  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debentures.

    (c)  The Trustee shall not be accountable for the use or application by
the Company of any of the Debentures or of the proceeds of such Debentures,
or for the use or application of any moneys paid over by the Trustee in
accordance with any provision of this Indenture or established pursuant to
Section 2.01, or for the use or application of any moneys received by any
paying agent other than the Trustee.

    SECTION 7.04.  TRUSTEE, PAYING AGENT OR DEBENTURE REGISTRAR MAY OWN
DEBENTURES.  The Trustee or any paying agent or Debenture Registrar, in its
individual or any other capacity, may become the owner or pledgee of Debentures
and, subject to Sections 7.08 and 7.13, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, paying agent or Debenture
Registrar.

    SECTION 7.05.  MONEYS RECEIVED BY TRUSTEE TO BE HELD IN TRUST WITHOUT
INTEREST.  Subject to the provisions of Section 11.05, all moneys received by
the 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 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.

                                   38
<PAGE>

    SECTION 7.06.  TRUSTEE ENTITLED TO COMPENSATION, REIMBURSEMENT AND
INDEMNITY.  (a) The Company covenants and agrees to pay to the Trustee from time
to time, and the Trustee shall be entitled to, such compensation as the Company
and the Trustee shall from time to time agree in writing (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) for all services rendered by it in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and
duties hereunder of the Trustee, and the Company will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any of the provisions of this
Indenture (including the reasonable compensation and the reasonable expenses and
disbursements of its counsel and of all persons not regularly in its employ)
except any such expense, disbursement or advance as may arise from its
negligence or bad faith.  The Company also covenants to indemnify each of the
Trustee and its officers, agents, directors and employees for, and to hold them
harmless against, any loss, liability or expense including taxes (other than
taxes based upon, measured by or determined by the income of the Trustee)
incurred without negligence or bad faith on the part of the Trustee and arising
out of or in connection with the acceptance or administration of this trust,
including the reasonable costs and expenses of defending itself against any
claim of liability in the premises.  The provisions of this Section 7.06 shall
survive the termination of this Indenture and resignation or removal of the
Trustee.

    (b)  The obligations of the Company under this Section to compensate and
indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to
that of the Debentures upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the holders of
particular Debentures.

    SECTION 7.07.  RIGHT OF TRUSTEE TO RELY ON CERTIFICATE OF OFFICERS OF
COMPANY WHERE NO OTHER EVIDENCE SPECIFICALLY PRESCRIBED.  Except as otherwise
provided in Sections 7.01 and 7.02, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking or suffering or omitting
to take any action hereunder, such matter (unless other evidence in respect
thereof be herein specifically prescribed) may, in the absence of negligence or
bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted to be taken by it under the provisions of this Indenture upon the faith
thereof.

  SECTION 7.08.  DISQUALIFICATION; CONFLICTING INTERESTS.  If the Trustee has
or shall acquire any "conflicting interest" within the meaning of Section 310(b)
of the Trust Indenture Act, the Trustee and the Company shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act.
Nothing herein shall prevent the Trustee from filing with


                                   39
<PAGE>

the Commission the application referred to in the second to last paragraph of
said Section 310(b).

    SECTION 7.09.  REQUIREMENTS FOR ELIGIBILITY OF TRUSTEE.  There shall at all
times be a Trustee with respect to the Debentures issued hereunder which shall
at all times be a corporation or 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 or other
Person permitted to act as trustee by the Commission, authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least 50 million U.S. dollars, and subject to supervision or examination by
Federal, State, territorial, or District of Columbia authority.  If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section, 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.  The Company may not, nor
may any person directly or indirectly controlling, controlled by, or under
common control with the Company, serve as Trustee.  In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 7.10.

    SECTION 7.10.  RESIGNATION OF TRUSTEE AND APPOINTMENT OF SUCCESSOR.

    (a)  The Trustee or any successor hereafter appointed, may at any time
resign with respect to the Debentures of one or more series by giving written
notice thereof to the Company and by transmitting notice of resignation by mail,
first class postage prepaid, to the Debentureholders of such series, as their
names and addresses appear upon the Debenture Register.  Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee
with respect to Debentures of such series by written instrument, in duplicate,
one copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor trustee.  If no successor trustee shall have been so
appointed and have accepted appointment within 60 days after the mailing of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee with respect to
Debentures of such series, or any Debentureholder of that series who has been a
bona fide holder of a Debenture or Debentures for at least six months may,
subject to the provisions of Section 6.08, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee.  Such court may thereupon after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

  (b)  In case at any time any of the following shall occur:

       (1)  the Trustee shall fail to comply with the provisions of Section
       7.08 after written request therefor by the Company or by any
       Debentureholder who has

                                   40
<PAGE>

       been a bona fide holder of a Debenture or Debentures for at least
       six months; or

       (2)  the Trustee shall cease to be eligible in accordance with the
       provisions of Section 7.09 and shall fail to resign after written
       request therefor by the Company or by any such Debentureholder; or

       (3)  the Trustee shall become incapable of acting, or shall be
       adjudged  bankrupt or insolvent, or a receiver of the Trustee or of
       its property shall be appointed, or any public officer shall take
       charge or control of the Trustee or of its property or affairs for the
       purpose of rehabilitation, conservation or liquidation, then, in any
       such case, the Company may remove the Trustee with respect to all
       Debentures and appoint a successor trustee by written instrument, in
       duplicate, executed by order of the Board of Directors, one copy of
       which instrument shall be delivered to the Trustee so removed and one
       copy to the successor trustee.  If no successor trustee shall have
       been so appointed and have accepted appointment within 30 days after
       the mailing of such notice of removal, the Trustee so removed may
       petition any court of competent jurisdiction for the appointment of a
       successor trustee with respect to Debentures of such series, or any
       Debentureholder of that series who has been a bona fide holder of a
       Debenture or Debentures for at least six months may, subject to the
       provisions of Section 6.08, on behalf of himself and all others
       similarly situated, petition any such court for the removal of the
       Trustee and the appointment of a successor trustee.  Such court may
       thereupon after such notice, if any, as it may deem proper and
       prescribe, remove the Trustee and appoint a successor trustee.

    (c)  The holders of a majority in aggregate principal amount of the
Debentures of any series at the time outstanding may at any time remove the
Trustee with respect to such series and appoint a successor trustee.

    (d)  Any resignation or removal of the Trustee and appointment of a
successor trustee with respect to the Debentures of a series pursuant to any of
the provisions of this Section shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 7.11.

    (e)  Any successor trustee appointed pursuant to this Section may be
appointed with respect to the Debentures of one or more series or all of such
series, and at any time there shall be only one Trustee with respect to the
Debentures of any particular series.

    SECTION 7.11.  ACCEPTANCE BY SUCCESSOR TO TRUSTEE.

    (a)  In case of the appointment hereunder of a successor trustee with
respect to all Debentures, every such successor trustee so appointed shall
execute, acknowledge and

                                   41
<PAGE>

deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor trustee, such retiring Trustee shall, upon payment
of its charges, execute and deliver an instrument transferring to such
successor trustee all the rights, powers, and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor trustee all
property and money held by such retiring Trustee hereunder.

    (b)  In case of the appointment hereunder of a successor trustee with
respect to the Debentures of one or more (but not all) series, the Company, the
retiring Trustee and each successor trustee with respect to the Debentures of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor trustee shall accept such appointment and which shall (1)
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Debentures of that
or those series to which the appointment of such successor trustee relates, (2)
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Debentures of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee and that no Trustee shall be responsible for any act or
failure to act on the part of any other Trustee hereunder; and upon the
execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein,
such retiring Trustee shall with respect to the Debentures of that or those
series to which the appointment of such successor trustee relates have no
further responsibility for the exercise of rights and powers or for the
performance of the duties and obligations vested in the Trustee under this
Indenture, and each such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Debentures of that or those series
to which the appointment of such successor trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor trustee, to the extent contemplated by
such supplemental indenture, the property and money held by such retiring
Trustee hereunder with respect to the Debentures of that or those series to
which the appointment of such successor trustee relates.

    (c)  Upon request of any such successor trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor trustee all such rights, power and trusts referred to in
paragraph (a) or (b) of this Section 7.11, as the case may be.

                                   42
<PAGE>


    (d)  No successor trustee shall accept its appointment unless at the time
of such acceptance such successor trustee shall be qualified and eligible under
this Article.

    (e)  Upon acceptance of appointment by a successor trustee as provided in
this Section 7.11, the successor trustee shall transmit notice of the succession
of such trustee hereunder by mail, first class postage prepaid, to the
Debentureholders, as their names and addresses appear upon the Debenture
Register.

    SECTION 7.12.  SUCCESSOR TO TRUSTEE BY MERGER, CONSOLIDATION OR SUCCESSION
TO BUSINESS.  Any corporation or banking association into which the Trustee may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such corporation shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.  In case any Debentures shall have been authenticated,
but not made available for delivery, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and make available for delivery the Debentures so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Debentures.

    SECTION 7.13.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.  The
Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding
any creditor relationship described in Section 311(b) of the Trust Indenture
Act.  A Trustee who has resigned or been removed shall be subject to Section
311(a) of the Trust Indenture Act to the extent included therein as though such
resignation or removal, as the case may be, had not occurred.

                           ARTICLE 8
                   Concerning the Debentures

    SECTION 8.01.  EVIDENCE OF ACTION BY DEBENTUREHOLDERS.  Whenever in this
Indenture it is provided that the holders of a majority or specified percentage
in aggregate principal amount of the Debentures of a particular series may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action), the fact that at
the time of taking any such action the holders of such majority or specified
percentage of that series have joined therein may be evidenced by any instrument
or any number of instruments of similar tenor executed by such holders of
Debentures of that series in person or by agent or proxy appointed in writing.


                                   43
<PAGE>

If the Company shall solicit from the Debentureholders of any series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Debentureholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Debentureholders of record at the
close of business on the record date shall be deemed to be Debentureholders for
the purposes of determining whether Debentureholders of the requisite proportion
of Outstanding Debentures of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the Outstanding Debentures of that series
shall be computed as of the record date; provided that no such authorization,
agreement or consent by such Debentureholders on the record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after the record date.

    SECTION 8.02.  PROOF OF EXECUTION OF INSTRUMENTS AND OF HOLDING OF
DEBENTURES.  Subject to the provisions of Sections 7.01 and 7.02, proof of the
execution of any instrument by a Debentureholder (such proof will not require
notarization) or his agent or proxy and proof of the holding by any person of
any of the Debentures shall be sufficient if made in the following manner;

       (a)  The fact and date of the execution by any such person of any
       instrument may be proved in any reasonable manner acceptable to the
       Trustee.

       (b)  The ownership of Debentures shall be proved by the Debenture
       Register of such Debentures or by a certificate of the Debenture
       Registrar thereof.

       (c)  The Trustee may require such additional proof of any matter
       referred to in this Section as it shall deem necessary.

    SECTION 8.03.  WHO MAY BE DEEMED OWNERS OF DEBENTURES.  Prior to the due
presentment for registration of transfer of any Debenture, the Company, the
Trustee, any paying agent and any Debenture Registrar may deem and treat the
person in whose name such Debenture shall be registered in the Debenture
Register as the absolute owner of such Debenture (whether or not such Debenture
shall be overdue and notwithstanding any notice of ownership or writing thereon
made by anyone other than the Debenture Registrar) for the purpose of receiving
payment of or on account of the principal of, premium, if any, and (subject to
Section 2.03) interest on such Debenture and for all other purposes; and neither
the Company nor the Trustee nor any paying agent nor any Debenture Registrar
shall be affected by any notice to the contrary.


                                   44

<PAGE>

    SECTION 8.04.  DEBENTURES OWNED BY THE COMPANY OR CONTROLLED OR CONTROLLING
COMPANIES DISREGARDED FOR CERTAIN PURPOSES.  In determining whether the holders
of the requisite aggregate principal amount of Debentures of a particular series
have concurred in any direction, consent or waiver under this Indenture,
Debentures of that series which are owned by the Company or any other obligor on
the Debentures of that series or by any Subsidiary of the Company or of such
other obligor on the Debentures of that series shall be disregarded and deemed
not to be Outstanding for the purpose of any such determination, except that for
the purpose of determining whether the Trustee shall be protected in relying on
any such direction, consent or waiver, only Debentures of such series which a
Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded.  Debentures so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right so to act with
respect to such Debentures and that the pledgee is not a person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor.  In case of a dispute as to
such right, any decision by the Trustee taken upon the advice of counsel shall
be full protection to the Trustee.

    SECTION 8.05.  INSTRUMENTS EXECUTED BY DEBENTUREHOLDERS BIND FUTURE
HOLDERS.  At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Debentures of a
particular series specified in this Indenture in connection with such action,
any holder of a Debenture of that series which is shown by the evidence to be
included in the Debentures the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.02, revoke such action so far as concerns such Debenture.
Except as aforesaid any such action taken by the holder of any Debenture shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Debenture, and of any Debenture issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Debenture.  Any action
taken by the holders of the majority or percentage in aggregate principal amount
of the Debentures of a particular series specified in this Indenture in
connection with such action shall be conclusively binding upon the Company, the
Trustee and the holders of all the Debentures of that series.

    SECTION 9.01.  PURPOSES FOR WHICH SUPPLEMENTAL INDENTURE MAY BE ENTERED
INTO WITHOUT CONSENT OF DEBENTUREHOLDERS.  In addition to any supplemental
indenture otherwise authorized by this Indenture, the Company and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the

                                   45
<PAGE>

provisions of the Trust Indenture Act as then in effect), without the consent
of the Debentureholders, for one or more of the following purposes:

       (a) to evidence the succession of another corporation or other entity
       to the Company, and the assumption by any such successor of the
       obligations of the Company contained herein or otherwise established
       with respect to the Debentures;

       (b) to add further covenants, restrictions, conditions or provisions
       for the protection of the holders of the Debentures of all or any
       series as the Board of Directors and the Trustee shall consider to be
       for the protection of the holders of Debentures of all or any series,
       and to make the occurrence, or the occurrence and continuance, of a
       default in any of such additional covenants, restrictions, conditions
       or provisions a default or an Event of Default with respect to such
       series permitting the enforcement of all or any of the several
       remedies provided in this Indenture as herein set forth; provided,
       however, that in respect of any such additional covenant, restriction,
       condition or provision such supplemental indenture may provide for a
       particular period of grace after default (which period may be shorter
       or longer than that allowed in the case of other defaults) or may
       provide for an immediate enforcement upon such default or may limit
       the remedies available to the Trustee upon such default or may limit
       the right of the holders of a majority in aggregate principal amount
       of the Debentures of such series to waive such default;

       (c) to cure any ambiguity or to correct or supplement any provision
       contained herein or in any supplemental indenture which may be
       defective or inconsistent with any other provision contained herein or
       in any supplemental indenture, or to make such other provisions in
       regard to matters or questions arising under this Indenture as shall
       not be inconsistent with the provisions of this Indenture and shall
       not materially adversely affect the interests of the holders of the
       Debentures of any series;

       (d) to add to, change or eliminate any of the provisions of this
       Indenture, provided that any such addition, change or elimination
       shall become effective only when there is no Debenture outstanding of
       any series created prior to the execution of such supplemental
       indenture which is entitled to the benefit of such provision;

       (e) to provide for the issuance under this Indenture of Debentures in
       coupon form (including Debentures registrable as to principal only)
       and to provide for exchangeability of such Debentures with the
       Debentures issued hereunder in fully registered form and to make all
       appropriate changes for such purposes;


                                   46
<PAGE>

       (f) to evidence and provide for the acceptance of appointment hereunder
       by a successor trustee with respect to the Debentures;

       (g) to qualify or maintain qualification of this Indenture under the
       Trust Indenture Act;

       (h) to establish the form or terms of Debentures of any series as
       permitted by Section 2.01; or

       (i) to make any addition, change or elimination of any provision of
       this Indenture that does not adversely affect the rights of any
       Debentureholder in any material respect.

    The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, and to make any further appropriate
agreements and stipulations which may be therein contained, but the Trustee
shall not be obligated to, but may in its discretion, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

    Any supplemental indenture authorized by the provisions of this Section may
be executed by the Company and the Trustee without the consent of the holders of
any of the Debentures at the time outstanding, notwithstanding any of the
provisions of Section 9.02.

    SECTION 9.02.  MODIFICATION OF INDENTURE WITH CONSENT OF DEBENTUREHOLDERS.
With the consent (evidenced as provided in Section 8.01) of the holders of not
less than a majority in aggregate principal amount of the Debentures of each
series affected by such supplemental indenture or indentures at the time
outstanding (and, in the case of any series of Debentures held as trust assets
of a Trust and with respect to which a Security Exchange has not theretofore
occurred, such consent of holders of the Preferred Securities and the Common
Securities of such Trust as may be required under the Declaration of Trust of
such Trust), the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect) for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the holders of the Debentures of such series under this
Indenture; provided, however, that no such supplemental indenture shall (i)
extend the fixed maturity of any Debentures of any series, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable upon the redemption thereof,
without the consent of the holder of each Debenture so affected or (ii) reduce
the aforesaid percentage of Debentures, the holders of which are required to
consent to any such supplemental indenture, without the consent of the holders
of each Debenture (and, in the case of any series of Debentures held as trust
assets of a Trust and with respect to which a Security Exchange has not
theretofore occurred, such consent of the

                                   47
<PAGE>


holders of the Preferred Securities and the Common Securities of such Trust
as may be required under the Declaration of Trust of such Trust) then
outstanding and affected thereby.

    Upon the request of the Company, and upon the filing with the Trustee of
evidence of the consent of Debentureholders (and, in the case of any series
of Debentures held as trust assets of a Trust and with respect to which a
Security Exchange has not theretofore occurred, such consent of holders of
the Preferred Securities and the Common Securities of such Trust as may be
required under the Declaration of Trust of such Trust) required to consent
thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture
or otherwise, in which case the Trustee may in its discretion but shall not
be obligated to enter into such supplemental indenture.

    It shall not be necessary for the consent of the Debentureholders of any
series affected thereby under this Section to approve the particular form of
any proposed supplemental indenture, but it shall be sufficient if such
consent shall approve the substance thereof.

    Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice,
setting forth in general terms the substance of such supplemental indenture,
to the Debentureholders of all series affected thereby as their names and
addresses appear upon the Debenture Register.  Any failure of the Trustee to
mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture.

    SECTION 9.03.  EFFECT OF SUPPLEMENTAL INDENTURES.  Upon the execution of
any supplemental indenture pursuant to the provisions of this Article or of
Section 10.01, this Indenture shall, with respect to such series, be and be
deemed to be modified and amended in accordance therewith and the respective
rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Debentures of the
series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental
indenture shall be and be deemed to be part of the terms and conditions of
this Indenture for any and all purposes.

    SECTION 9.04.  DEBENTURES MAY BEAR NOTATION OF CHANGES BY SUPPLEMENTAL
INDENTURES.  Debentures of any series, affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental
indenture pursuant to the provisions of this Article or of Section 10.01, may
bear a notation in form approved by the Company, provided such form meets the
requirements of any exchange upon which such series may be listed or traded,
as to any matter provided for in such supplemental indenture.  If the Company
shall so determine, new Debentures of that series so modified as to conform,
in the opinion of the Board of Directors, to any modification of this
Indenture contained in any such

                                   48
<PAGE>

supplemental indenture may be prepared by the Company, authenticated by the
Trustee and delivered in exchange for the Debentures of that series then
outstanding.

    SECTION 9.05.  OPINION OF COUNSEL.  The Trustee, subject to the provisions
of Sections 7.01 and 7.02, may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant hereto complies with
the requirements of this Article 9.

               CONSOLIDATION, MERGER, SALE OR CONVEYANCE

    SECTION 10.01.  COMPANY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.  The
Company shall not consolidate with or merge into any other Person or convey,
transfer or lease its properties and assets substantially as an entirety to any
other Person, and the Company shall not permit any other Person to consolidate
with or merge into the Company, unless:

            (a)  either the Company shall be the continuing corporation, or
       the corporation (if other than the Company) formed by such
       consolidation or into which the Company is merged or to which the
       properties and assets of the Company substantially as an entity are
       transferred or leased shall be a corporation, limited liability
       company, partnership or trust organized and existing under the laws of
       the United States of America or any state thereof or the District of
       Columbia and shall expressly assume, by an indenture supplemental
       hereto, executed and delivered to the Trustee, in form satisfactory to
       the Trustee, all the obligations of the Company under the Debentures
       and this Indenture; and

            (b)  immediately after giving effect to such transaction no Event
       of Default, and no event which, after notice or lapse of time or both,
       would become an Event of Default, shall have occurred and be
       continuing.

    SECTION 10.02.  SUCCESSOR CORPORATION SUBSTITUTED.  The successor
corporation formed by such consolidation or into which the Company is merged
or to which such transfer or lease is made shall succeed to and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor corporation had been
named as the Company herein, and thereafter (except in the case of a lease to
another Person) the predecessor corporation shall be relieved of all
obligations and covenants under the Indenture and the Debentures and, in the
event of such conveyance or transfer, any such predecessor corporation may be
dissolved and liquidated.

    SECTION 10.03.  OPINION OF COUNSEL.  The Trustee, subject to the provisions
of Sections 7.01 and 7.02, may receive an Opinion of Counsel as conclusive
evidence that any

                                   49
<PAGE>

such consolidation, merger, sale, conveyance, transfer or other disposition,
and any such assumption, comply with the provisions of this Article.

in such amounts as will insure the availability of cash, or a combination
thereof, sufficient in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay (A) the principal of, premium, if any, and
interest on all Debentures of such series on each date that such principal or
interest is due and payable and (B) any mandatory sinking fund payments on the
dates on which such payments are due and payable in accordance with the terms of
the Indenture and the Debentures of such series; and if, in any such case, the

demand of the Company accompanied by an Officers' Certificate and an Opinion
of Counsel and at the cost and expense of the Company, shall execute proper
instruments acknowledging such satisfaction of and discharging this
Indenture; provided, that the rights of the Debentureholders to receive
amounts in respect of principal of, premium, if any, and interest on the
Debentures held by them shall not be delayed longer than required by
then-applicable mandatory rules or policies of any securities exchange or
automated quotation system upon which the Debentures are listed or traded.
The Company agrees to reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred and to compensate the Trustee for
any services thereafter reasonably and properly rendered by the Trustee in
connection with this Indenture or the Debentures of such series.

    (B)  The following provisions shall apply to the Debentures of each series
unless specifically otherwise provided in a Board Resolution or indenture
supplemental hereto provided pursuant to Section 2.01.  In addition to discharge
of the Indenture pursuant to the next preceding paragraph, the Company shall be
deemed to have paid and discharged the entire indebtedness on all the Debentures
of a series on the date of the deposit referred to in subparagraph (a) below,
and the provisions of this Indenture with respect to the Debentures of such
series shall no longer be in effect (except as to (i) rights of registration of
transfer and exchange of Debentures of such series and the Company's right of
optional redemption, if any, (ii) substitution of mutilated, defaced, destroyed,
lost or stolen Debentures, (iii) rights of holders of Debentures to receive

expense of the Company, shall at the Company's request, execute proper
instruments acknowledging the same, if

       (a)  with reference to this provision the Company has irrevocably
       deposited or caused to be irrevocably deposited with the Trustee as
       trust funds in trust, specifically pledged as security for, and
       dedicated solely to, the benefit of the holders of the Debentures of
       such series (i) cash in an amount, or (ii) Governmental Obligations
       maturing as to principal and interest at such times and in such
       amounts as will insure the availability of cash or (iii) a combination
       thereof, sufficient, in the opinion of a nationally recognized firm of
       independent public accountants expressed in a written certification
       thereof delivered to the Trustee, to pay (A) the principal of, or
       premium, if any, and interest on all Debentures of such series on each
       date that such principal or interest is due and payable and (B) any
       mandatory sinking fund payments on the dates on which such payments
       are due and payable in accordance with the terms of the Indenture and
       the Debentures of such series;

       (b)  such deposit will not result in a breach or violation of, or
       constitute a default under, any agreement or instrument to which the
       Company is a party or by which it is bound;

                                   51
<PAGE>

       (c)  the Company has delivered to the Trustee an Opinion of Counsel
       based on the fact that (x) the Company has received from, or there has
       been published by, the Internal Revenue Service a ruling or (y) since
       the date hereof, there has been a change in the applicable Federal
       income tax law, in either case to the effect that, and such opinion
       shall confirm that, the holders of the Debentures of such series will
       not recognize income, gain or loss for Federal income tax purposes as
       a result of such deposit, defeasance and discharge and will be subject
       to Federal income tax on the same amount and in the same manner and at
       the same times, as would have been the case if such deposit,
       defeasance and discharge had not occurred;

       (d)  the Company has delivered to the Trustee an Officers' Certificate
       and an Opinion of Counsel, each stating that all conditions precedent
       provided for relating to the defeasance contemplated by this provision
       have been complied with; and

       (e)   no event or condition shall exist that, pursuant to the
       provisions of Section 14.02 or 14.03, would prevent the Company from
       making payments of the principal of, premium, if any, or interest on
       the Debentures of such series on the date of such deposit.

    SECTION 11.02.  APPLICATION BY TRUSTEE OF FUNDS DEPOSITED FOR PAYMENT OF
DEBENTURES.  Subject to Section 11.04, all moneys deposited with the Trustee (or
other trustee) pursuant to Section 11.01 shall be held in trust and applied by
it to the payment, either directly or through any paying agent (including the
Company acting as its own paying agent), to the Holders of the particular
Debentures of such series for the payment or redemption of which such moneys
have been deposited with the Trustee, of all sums due and to become due thereon
for principal and interest; but such money need not be segregated from other
funds except to the extent required by law.

    SECTION 11.03.  REPAYMENT OF MONEYS HELD BY THE PAYING AGENT.  In connection
with the satisfaction and discharge of this Indenture with respect to
Debentures of any series, all moneys then held by any paying agent under the
provisions of this Indenture with respect to such series of Debentures shall,
upon demand of the Company, be repaid to it or paid to the Trustee and
thereupon such paying agent shall be released from all further liability with
respect to such moneys.

    SECTION 11.04.  REPAYMENT OF MONEYS HELD BY THE TRUSTEE.  Any moneys
deposited with or paid to the Trustee or any paying agent for the payment of the
principal of or interest on any Debenture of any series and not applied but
remaining unclaimed for two years after the date upon which such principal or
interest shall have become due and payable, shall, upon the written request of
the Company and unless otherwise required by mandatory provisions of applicable
escheat or abandoned or unclaimed property law, be repaid to the Company by the
Trustee for such series or such paying agent, and a holder of the Debentures of
such series


                                   52
<PAGE>


shall, unless otherwise required by mandatory provisions of applicable
escheat or abandoned or unclaimed property laws, thereafter look only to the
Company for any payment which such holder may be entitled to collect, and all
liability of the Trustee or any paying agent with respect to such moneys
shall thereupon cease; provided, however, that the Trustee or such paying
agent, before being required to make any such repayment with respect to
moneys deposited with it for any payment series, shall at the expense of the
Company, mail by first-class mail to holders of such Debentures at their
addresses as they shall appear on the Debenture Register, notice, that such
moneys remain and that, after a date specified therein, which shall not be
less than 30 days from the date of such mailing or publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

    SECTION 11.05.  INDEMNIFICATION RELATING TO GOVERNMENTAL OBLIGATIONS.  The
Company shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the Governmental Obligations deposited pursuant
to Section 11.01 or the principal or interest received in respect of such
obligations.

corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Debentures or implied therefrom;
and that any and all such personal liability of every name and nature, either at
common law or in equity or by constitution or statute, of, and any and all such
rights and claims against, every such incorporator, stockholder, officer or
director as such, because of the creation of the indebtedness hereby authorized,
or under or by reason of the obligations, covenants or agreements contained in

expressly waived and released as a condition of, and as a consideration for, the
execution of this Indenture and the issuance of such Debentures.

except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of
this Indenture relating to such particular application or demand, no
additional certificate or opinion need be furnished.

    (b)  Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
in this Indenture (other than the certificate provided pursuant to Section
5.03(d) of this Indenture) shall include (1) a statement that the person making
such certificate or opinion has read such covenant or condition; (2) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are

    SECTION 13.07.  PAYMENTS DUE ON SUNDAYS OR HOLIDAYS.  Except as provided
pursuant to Section 2.01 pursuant to a Board Resolution, and as set forth in an
Officers' Certificate, or established in one or more indentures supplemental to
the Indenture, in any case where the date of maturity of interest or principal
of any Debenture or the date of redemption of any Debenture shall not be a
Business Day, then payment of interest or principal (and premium, if any) may be
made on the next succeeding Business Day, with the same force and effect as if
made on the nominal date of maturity or redemption, and no interest shall accrue
for the period after such nominal date.

    SECTION 13.08.  PROVISIONS REQUIRED BY TRUST INDENTURE ACT OF 1939 TO
CONTROL.  If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control.

    SECTION 13.09.  INDENTURE MAY BE EXECUTED BY ITS COUNTERPARTS.  This
Indenture may be executed in any number of counterparts, each of which shall be
an original; but such counterparts shall together constitute but one and the
same instrument.

    SECTION 13.10.  SEPARABILITY OF INDENTURE PROVISIONS.  In case any one or
more of the provisions contained in this Indenture or in the Debentures of any
series shall for any reason be held to be invalid, illegal or unenforceable in
any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Indenture or of such Debentures, but this Indenture
and such Debentures shall be construed as if such invalid or illegal or
unenforceable provision had never been contained herein or therein.

    SECTION 13.11.  ASSIGNMENT BY COMPANY TO A SUBSIDIARY OR AFFILIATE.  The
Company will have the right at all times to assign any of its rights or
obligations under this Indenture to a Subsidiary or an Affiliate of the Company;
provided that, in the event of any such assignment, the Company will remain
jointly and severally liable for all such obligations.

                                      55

Subject to the foregoing, this Indenture is binding upon and inures to the
benefit of the parties thereto and their respective successors and assigns.
This Indenture may not otherwise be assigned by the parties hereto (other
than pursuant to Article 10).

    SECTION 13.12.  HOLDERS OF PREFERRED SECURITIES AS THIRD PARTY
BENEFICIARIES OF THE INDENTURE; HOLDERS OF PREFERRED SECURITIES MAY INSTITUTE
LEGAL PROCEEDINGS AGAINST THE COMPANY IN CERTAIN CASES.  The Company
acknowledges that, prior to a Security Exchange with respect to Debentures of
any series held as trust assets of a Trust, if the Property Trustee of such
Trust fails to enforce its rights under this Indenture as the holder of the
Debentures of a series held as trust assets of such Trust, any holder of the
Preferred Securities of such Trust may in accordance with the provisions of the
Declaration of Trust of such Trust, to the fullest extent permitted by law,
institute legal proceedings directly against the Company to enforce such
Property Trustee's rights under this Indenture without first instituting any
legal proceedings against such Property Trustee or any other Person; PROVIDED
that, if an Event of Default has occurred and is continuing and such event is
attributed to the failure of the Company 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 of such Trust 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 Company shall be subrogated to the rights of such holder of
Preferred Securities to the extent of any payment made by the Company to such
holders of Preferred Securities in such Holder Direct Action.  Except as
provided in the preceding sentences, the holders of Preferred Securities of such
Trust shall not be able to exercise directly any other remedy available to the
holders of the Debentures.


                                   ARTICLE 14
                          SUBORDINATION OF DEBENTURES

    SECTION 14.01.  AGREEMENT TO SUBORDINATE. The Company covenants and agrees,
and each Debentureholder issued hereunder by his acceptance thereof likewise
covenants and agrees, that all Debentures shall be issued subject to the
provisions of this Article 14; and each person holding any Debenture, whether
upon original issue or upon transfer, assignment or exchange thereof accepts and
agrees to be bound by such provisions.

    The payment by the Company of the principal of, premium, if any, and
interest on all Debentures issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
all Senior Debt, whether outstanding at the date of this Indenture or thereafter
incurred.

                                      56
<PAGE>

    No provision of this Article 14 shall prevent the occurrence of any Default
or Event of Default hereunder.

    SECTION 14.02.  DEFAULT ON SENIOR DEBT.  In the event and during the
continuation of any default by the Company in the payment of principal, premium,
interest or any other payment due on any Senior Debt, or in the event that the
maturity of any Senior Debt has been accelerated because of a default, then, in
either case, no payment shall be made by the Company with respect to the
principal (including redemption payments) of or premium, if any, or interest on
the Debentures until such default shall have been cured or waived in writing or
shall have ceased to exist or such Senior Debt shall have been discharged or
paid in full.

    In the event of the acceleration of the maturity of the Debentures, then no
payment shall be made by the Company with respect to the principal (including
redemption payments) of or premium, if any, or interest on the Debentures until
the holders of all Senior Debt outstanding at the time of such acceleration
shall receive payment in full of such Senior Debt (including any amounts due
upon acceleration).

    In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or any Debentureholder when such payment is prohibited
by the preceding paragraphs of this Section 14.02, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Senior Debt or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Debt may have been
issued, as their respective interests may appear.

    SECTION 14.03.  LIQUIDATION; DISSOLUTION; BANKRUPTCY.  Upon any payment by
the Company or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any liquidation,
dissolution, winding up, receivership, reorganization, assignment for the
benefit of creditors, marshaling of assets and liabilities or any bankruptcy,
insolvency or similar proceedings of the Company, all amounts due or to become
due upon all Senior Debt shall first be paid in full, in cash or cash
equivalents, or payment thereof provided for in accordance with its terms,
before any payment is made on account of the principal of, premium, if any, or
interest on the indebtedness evidenced by the Debentures, and upon any such
liquidation, dissolution, winding up, receivership, reorganization, assignment,
marshaling or proceeding, any payment or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, to which the
Debentureholders or the Trustee under this Indenture would be entitled, except
for the provisions of this Article 14, shall be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Debentureholders or by the
Trustee under this Indenture if received by them or it, directly to the holders
of Senior Debt (pro rata to such holders on the basis of the respective amounts
of Senior Debt held by such holders) or their respective representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing any of such Senior Debt may have been issued, as their respective

                                      57
<PAGE>

interests may appear, to the extent necessary to pay all Senior Debt in full
(including, without limitation, except to the extent, if any, prohibited by
mandatory provisions of law, post-petition interest, in any such proceedings),
after giving effect to any concurrent payment or distribution to or for the
holders of Senior Debt, before any payment or distribution is made to the
holders of the indebtedness evidenced by the Debentures or to the Trustee under
this Indenture.

    In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee under this Indenture or the holders of the Debentures before all Senior
Debt is paid in full or provision is made for such payment in accordance with
its terms, such payment or distribution shall be held in trust for the benefit
of and shall be paid over or delivered to the holders of such Senior Debt or
their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any of such Senior Debt
may have been issued, as their respective interests may appear, for application
to the payment of all Senior Debt remaining unpaid until all such Senior Debt
shall have been paid in full in accordance with its terms, after giving effect
to any concurrent payment or distribution to or for the holders of such Senior
Debt.

    For purposes of this Article 14, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of arrangement, reorganization or readjustment, the payment of which
is subordinated (at least to the extent provided in this Article 14 with respect
to the Debentures) to the payment of all Senior Debt which may at the time be
outstanding; PROVIDED, that (i) the Senior Debt is assumed by the new
corporation, if any, resulting from any such arrangement, reorganization or
readjustment, and (ii) the rights of the holders of the Senior Debt are not,
without the consent of such holders, altered by such arrangement, reorganization
or readjustment.  The consolidation of the Company with, or the merger of the
Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another corporation upon the terms and
conditions provided in Article 10 shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section if such other
Person shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions stated in Article 10.  Nothing in Section 14.02 or
this Section 14.03 shall apply to claims of, or payments to, the Trustee under
or pursuant to Article 7, except as provided therein.  This Section shall be
subject to the further provisions of Section 14.06.

    SECTION 14.04.  SUBROGATION OF DEBENTURES. Subject to the payment in full
of all Senior Debt, the rights of the holders of the Debentures shall be
subrogated to the rights of the holders of Senior Debt to receive payments or
distributions of cash, property or securities of the Company applicable to the
Senior Debt until the principal of, premium, if any, and interest on the
Debentures shall be paid in full; and, for the purposes of such

                                      58
<PAGE>

subrogation, no payments or distributions to the holders of the Senior Debt
of any cash, property or securities to which the holders of the Debentures or
the Trustee on their behalf would be entitled except for the provisions of
this Article 14 and no payment over pursuant to the provisions of this
Article 14 to the holders of Senior Debt by holders of the Debentures or the
Trustee on their behalf shall, as between the Company, its creditors other
than holders of Senior Debt and the holders of the Debentures, be deemed to
be a payment by the Company to or on account of the Senior Debt; and no
payments or distributions of cash, property or securities to or for the
benefit of the Debentureholders pursuant to the subrogation provisions of
this Article, which would otherwise have been paid to the holders of Senior
Debt shall be deemed to be a payment by the Company to or for the account of
the Debentures.  It is understood that the provisions of this Article 14 are
and are intended solely for the purpose of defining the relative rights of
the holders of the Debentures, on the one hand, and the holders of the Senior
Debt, on the other hand.

    Nothing contained in this Article 14 or elsewhere in this Indenture or in
the Debentures is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Debt, and the holders of the
Debentures, the obligation of the Company, which is absolute and unconditional,
to pay to the holders of the Debentures the principal of, premium, if any, and
interest on the Debentures as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the holders of the Debentures and creditors of the Company other than
the holders of the Senior Debt, nor shall anything herein or therein prevent the
holder of any Debenture or the Trustee on his behalf from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article 14 of the holders
of Senior Debt in respect of cash, property or securities of the Company
received upon the exercise of any such remedy.

    Upon any payment or distribution of assets of the Company referred to in
this Article 14, the Trustee, subject to the provisions of Article 7, and the
holders of the Debentures shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which such liquidation,
dissolution, winding up, receivership, reorganization, assignment or marshaling
proceedings are pending, or a certificate of the receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, delivered to the Trustee or to the holders of the Debentures, for
the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 14.

    SECTION 14.05.  AUTHORIZATION BY DEBENTUREHOLDERS.  Each holder of a
Debenture by his acceptance thereof authorizes and directs the Trustee in his
behalf to take such action as may be necessary or appropriate to effectuate
the subordination provided in this Article 14 and appoints the Trustee his
attorney-in-fact for any and all such purposes.

                                      59
<PAGE>

    SECTION 14.06.  NOTICE TO TRUSTEE. The Company shall give prompt written
notice to the Trustee and to any paying agent of any fact known to the
Company which would prohibit the making of any payment of moneys to or by the
Trustee or any paying agent in respect of the Debentures pursuant to the
provisions of this Article 14.  Regardless of anything to the contrary
contained in this Article 14 or elsewhere in this Indenture, the Trustee
shall not be charged with knowledge of the existence of any Senior Debt or of
any default or event of default with respect to any Senior Debt or of any
other facts which would prohibit the making of any payment of moneys to or by
the Trustee, unless and until the Trustee shall have received notice in
writing at its principal Corporate Trust Office to that effect signed by an
officer of the Company, or by a holder or agent of a holder of Senior Debt
who shall have been certified by the Company or otherwise established to the
reasonable satisfaction of the Trustee to be such holder or agent, or by the
trustee under any indenture pursuant to which Senior Debt shall be
outstanding, and, prior to the receipt of any such written notice, the
Trustee shall, subject to the provisions of Article 7, be entitled to assume
that no such facts exist; PROVIDED, HOWEVER, that if on a date at least three
Business Days prior to the date upon which by the terms hereof any such
moneys shall become payable for any purpose (including, without limitation,
the payment of the principal of, or interest on any Debenture) the Trustee
shall not have received with respect to such moneys the notice provided for
in this Section 14.06, then, regardless of anything herein to the contrary,
the Trustee shall have full power and authority to receive such moneys and to
apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary which may be received by it on or
after such prior date.

    The Trustee shall be entitled to conclusively rely on the delivery to it of
a written notice by a Person representing himself to be a holder of Senior Debt
(or a trustee on behalf of such holder) to establish that such notice has been
given by a holder of Senior Debt or a trustee on behalf of any such holder.  In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article 14, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Debt held by such Person,
the extent to which such Person is entitled to participate in such payment or
distribution and any other facts pertinent to the rights of such Person under
this Article 14, and if such evidence is not furnished the Trustee may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment.

    SECTION 14.07.  TRUSTEE'S RELATION TO SENIOR DEBT.  The Trustee and any
agent of the Company or the Trustee shall be entitled to all the rights set
forth in this Article 14 with respect to any Senior Debt which may at any time
be held by it in its individual or any other capacity to the same extent as any
other holder of Senior Debt and nothing in this Indenture shall deprive the
Trustee or any such agent, of any of its rights as such holder.  Nothing in this
Article 14 shall apply to claims of, or payments to, the Trustee under or
pursuant to Article 7.

                                      61
<PAGE>

    With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 14, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt and, subject to the provisions of
Article 7, the Trustee shall not be liable to any holder of Senior Debt if it
shall pay over or deliver to holders of Debentures, the Company or any other
person moneys or assets to which any holder of Senior Debt shall be entitled by
virtue of this Article 14 or otherwise.

    SECTION 14.08.  NO IMPAIRMENT TO SUBORDINATION.  No right of any present or
future holder of any Senior Debt to enforce subordination as herein provided
shall at any time in any way be prejudiced or impaired by any act or failure to
act on the part of the Company or by any act or failure to act, in good faith,
by any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
which any such holder may have or otherwise be charged with.

    Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Debentureholders, without incurring
responsibility to the Debentureholders and without impairing or releasing the
subordination provided in this Article 14 or the obligations hereunder of the
holders of the Debentures to the holders of such Senior Debt, do any one or more
of the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, such Senior Debt, or otherwise amend or
supplement in any manner such Senior Debt or any instrument evidencing the same
or any agreement under which such Senior Debt is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Debt; (iii) release any Person liable in any
manner for the collection of such Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Company, as the case may be, and any other
Person.

    SECTION 14.09.  ARTICLE APPLICABLE TO PAYING AGENTS.  In case at any time
any paying agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article 14
shall in such case (unless the context otherwise requires) be construed as
extending to and including such paying agent within its meaning as fully for all
intents and purposes as if such paying agent were named in this Article 14 in
addition to or in place of the Trustee.

    SECTION 14.10.  TRUST MONEYS NOT SUBORDINATED.  Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of U.S.
Government Obligations held in trust under Section 11.02 of this Indenture by
the Trustee for the payment of principal of and interest on the Debentures
shall not be subordinated to the prior payment of any Senior Debt or subject
to the restrictions set forth in this Article 14, and none of the

                                      62
<PAGE>

Debentureholders shall be obligated to pay over any such amount to the
Company or any holder of Senior Debt or any other creditor of the Company.

    Wilmington Trust Company, as Trustee, hereby accepts the trust in this
Indenture declared and provided, upon the terms and conditions herein above
set forth.

                                      63

    IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed as of the day and year first above written.

         SUPPLEMENTAL INDENTURE NO. 1, dated as of the first day of June, 1999,
between Pogo Producing Company, a corporation duly organized and existing under
the laws of the State of Delaware (the "Company"), and Wilmington Trust Company,
a Delaware banking corporation, as trustee (the "Trustee").

                                       RECITALS

         The Company has heretofore executed and delivered to the Trustee a
Junior Subordinated Indenture, dated as of June 1, 1999 (the "Indenture"),
providing for the issuance from time to time of one or more series of its
unsecured junior subordinated debentures (the "Debentures").

         Pursuant to the terms of the Indenture, the Company desires to provide
for the establishment of a new series of Debentures to be designated as the
6 1/2% Junior Subordinated Convertible Debentures, Series A due 2029 (the
"Series A Debentures"), the form and substance of such Series A Debentures and
the terms, provisions and conditions thereof to be as set forth or provided in
the Indenture and this Supplemental Indenture No. 1.

         The Company has caused Pogo Trust I ("Pogo Trust I") to be created as
a statutory business trust under the Business Trust Act of the State of Delaware
(12 DEL. CODE Section  3801 ET SEQ.) pursuant to a Declaration of Trust, dated
as of March 17, 1999 (the "Original Declaration"), and the filing of a
Certificate of Trust with the Secretary of State of the State of Delaware on
March 18, 1999.

         The Original Declaration is to be amended and restated in its entirety
pursuant to an Amended and Restated Declaration of Trust dated as of June 2,
1999 (such Amended and Restated Declaration of Trust, as amended from time to
time, the "Declaration of Trust").

         Pogo Trust I desires to issue $150,000,000 aggregate liquidation
amount of its 6 1/2% Cumulative Quarterly Income Convertible Preferred
Securities, Series A (the "Preferred Securities") and sell such Preferred
Securities to the underwriters set forth in that certain Underwriting Agreement
dated May 26, 1999 (the "Underwriting Agreement") by and among the Company, Pogo
Trust I and the underwriters named therein.

         In connection with such purchases of Preferred Securities and the
related purchases by the Company of the Common Securities (as defined in the
Declaration of Trust) of Pogo Trust I, Pogo Trust I will purchase and hold as
trust assets up to $154,640,000 aggregate principal amount of the Series A
Debentures.

         Pursuant to the Declaration of Trust, the legal title to the Series A
Debentures shall be owned and held of record in the name of Wilmington Trust
Company or its successor under the Declaration of Trust, as Property Trustee

authorized a series of Debentures designated as the "6 1/2% Junior Subordinated
Convertible Debentures Series A due 2029" (the "Series A Debentures").

         SECTION 2.02.  Limitation on Aggregate Principal Amount.  The
aggregate principal amount of the Series A Debentures shall be limited to

mature and the principal amount thereof shall be due and payable together
with all accrued and unpaid interest thereon, including Additional Interest

PROVIDED, if a Tax Event occurs, then the Company will have the right (a)
prior to the dissolution of Pogo Trust I, to shorten the Maturity Date of the
Series A Debentures, to the minimum extent required, but not earlier than

2014, in each case such that in the opinion of an independent nationally
recognized counsel to the Company, experienced in such matters, after
shortening the Maturity Date, interest paid on the Series A Debentures will
be deductible for federal income tax purposes.

         (b) Whenever the Maturity Date is shortened in accordance with this
Section 2.03, a notice stating the Maturity Date has been adjusted and
setting forth the adjusted Maturity Date shall as soon as practicable be
mailed by the Company to all record holders of the Series A Debentures at

made at the option of the Company by check mailed to the registered holders at
such addresses as shall appear in the Debenture Register and that the payment of
principal with respect to the Series A Debentures will only be made upon
surrender of the Series A Debentures to the Trustee.  Notwithstanding the
foregoing, so long as the Property Trustee is the legal owner and record holder
of the Series A Debentures, the payment of the principal of and interest
(including Additional Interest and Compounded Interest, if any) on the Series A
Debentures held by the Property Trustee will be made by the Company in
immediately available funds on the payment date therefor at such place and to
the Property Account (as defined in the Declaration of Trust) established and
maintained by the Property Trustee pursuant to the Declaration of Trust.

              Trustee by the Property Trustee in exchange for one or more
              Global Debentures representing the Series A Debentures in an
              aggregate principal amount equal to all outstanding Series A
              Debentures, to be registered in the name of the Depositary, or
              its nominee, and delivered by the Trustee to the Depositary for
              crediting to the accounts of its participants pursuant to the
              instructions of the Regular Trustees.  The Company upon any such
              presentation shall execute one or more Global Debentures
              representing the Series A Debentures in such aggregate principal
              amount and deliver the same to the Trustee for authentication and
              delivery in accordance with the Indenture and this Supplemental
              Indenture No. 1.  Payments on the Series A Debentures issued as a
              Global Debenture will be made to the Depositary; and

         (ii) if any Preferred Securities are held in non book-entry
              certificated form, any Definitive Preferred Security Certificate
              (as defined in the Declaration of Trust) which represents
              Preferred Securities other than Preferred Securities held by the
              Clearing Agency (as defined in the Declaration of Trust) or its
              nominee ("Non Book-Entry Preferred Securities") will be deemed to
              represent beneficial interests in Series A Debentures presented
              to the Trustee by the Property Trustee having an aggregate
              principal amount equal to the aggregate liquidation amount of the
              Non Book-Entry Preferred Securities until such Definitive
              Preferred Security Certificate is presented to the Debenture
              Registrar for transfer or reissuance at which time such Preferred
              Security Certificate will be canceled and a Series A Debenture,

              Certificate or the transferee of the holder of such Preferred
              Security Certificate, as the case may be, with

                   liquidation amount of the Definitive Preferred Security
                   Certificate canceled will be executed by the Company and
                   delivered to the Trustee for authentication and delivery in
                   accordance with the Indenture and this Supplemental
                   Indenture No. 1.  Upon issuance of such Series A Debentures,
                   Series A Debentures with an equivalent aggregate amount that
                   were presented by the Property Trustee to the Trustee will
                   be deemed to have been canceled.

         SECTION 2.05.  Interest and Interest Rates.

         (a)  Each Series A Debenture will bear interest at the rate of 6 1/2%
per annum from June 2, 1999 until the principal thereof becomes due and payable,
and on any overdue principal and (to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the
same rate per annum (6 1/2%), compounded quarterly ("Compounded Interest"),
payable (subject to the provisions of Article Four) quarterly in arrears on
March 1, June 1, September 1 and December 1 of each year (each an "Interest
Payment Date"), commencing on September 1, 1999, to the person in whose name
such Series A Debenture or any predecessor Series A Debenture is registered, at

which, except as set forth below, shall be, in respect of any Series A
Debentures of which the Property Trustee is the registered holder or a Global
Debenture, the close of business on the Business Day next preceding that
Interest Payment Date.  Notwithstanding the foregoing sentence, if the Preferred
Securities are no longer in book-entry only form or if pursuant to the
provisions of Section 2.11(c) of the Indenture the Series A Debentures are not
represented by a Global Debenture, the regular record date for such interest
installment shall be the fifteenth day of the month preceding the month in which
that Interest Payment Date occurs.

         (b)  Any such interest installment not punctually paid or duly
provided for shall forthwith cease to be payable to the registered holders on
such regular record date, and shall instead be paid to the person in whose name
the Series A Debenture (or one or more Predecessor Debentures) is registered at
the close of business on a special record date to be fixed by the Trustee for
the payment of such defaulted interest, notice whereof shall be given to the
registered holders of the Series A Debentures not less than 10 days prior to
such special record date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange or quotation
system on which the Series A Debentures may be listed or traded, and upon such
notice as may be required by such exchange or quotation system, all as more
fully provided in Section 2.03 of the Indenture.

         (c)  The amount of interest payable for any full quarterly interest
period will be computed on the basis of a 360-day year of twelve 30-day months,
and for any period shorter than a full quarterly interest period for which
interest is computed, interest shall be computed on the basis of the actual
number of days elapsed per 90-day quarter.  In the event that any date on which
interest is payable on the Series A Debentures is not a Business Day, then


                                          10

<PAGE>

payment of interest payable on such date shall be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay), except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date such payment was originally payable.

         (d)  If at any time Pogo Trust I shall be required to pay any taxes,
duties, assessments or governmental charges of any nature (other than
withholding taxes) imposed by the Internal Revenue Service or any other taxing
authority, then, in any such case, the Company shall pay as additional interest
("Additional Interest") on the Series A Debentures such additional amounts as
shall be required so that the net amounts received and retained by Pogo Trust I
after paying any such taxes, duties, assessments or other governmental charges
shall be equal to the amounts Pogo Trust I would have received had no such
taxes, duties, assessments or other governmental charges been imposed.

         SECTION 2.06.  Denomination of Debentures.  The Series A Debentures
shall be in registered form without coupons and shall be issuable in
denominations of $50 and integral multiples thereof.

         SECTION 2.07.  Currency.  Payment of principal and interest on the
Series A Debentures shall be payable in U.S. dollars.

         SECTION 2.08.  Paying Agent.  The Trustee shall initially serve as
paying agent of the Series A Debentures.

         SECTION 2.09.  Sinking Fund Obligations.  The Company has no
obligation to redeem or purchase any Series A Debentures pursuant to any sinking
fund or analogous provisions (including payments made in cash in anticipation of
future sinking fund obligations) or at the option of a holder thereof.

         SECTION 2.10.  Additional Events of Default.

         (a)  The Events of Default specified in Section 6.01(a) of the
Indenture shall constitute Events of Default with respect to the Series A
Debentures, except as modified below.

         (b)  The Company's failure to pay interest on the Series A Debentures
for 30 days, subject to Company's right to extend the interest payment period of
the Series A Debentures provided in Article IV hereof, shall constitute an Event
of Default under the Indenture.

         (c)  The Company's failure to deliver Shares of Common Stock in
accordance with the provisions of Article V hereof upon appropriate election by
a holder of Series A Debentures to convert such Series A Debentures into Common
Stock shall constitute an Event of Default under the Indenture.

                Optional Redemption of the Series A Debentures

         SECTION 3.01.  Optional Redemption on or after June 1, 2002.

         (a)  Except as provided in Section 3.02 hereof and subject to the
provisions below, Series A Debentures shall not be redeemed by the Company prior
to June 1, 2002.  Subject to the terms of Article 3 of the Indenture, the
Company shall have the right to redeem the Series A Debentures, in whole or in
part, at any time from time to time on or after June 1, 2002, upon not less than
30 nor more than 60 days' notice to each holder of the Series A Debentures,
during the twelve-month periods commencing June 1 in each of the following years
at the indicated redemption price (expressed as a percentage of the principal
amount of the Series A Debentures being redeemed), together with any accrued and
unpaid interest thereon, including Compounded Interest and Additional Interest,
if any, to, but excluding, the date of such redemption (the "Optional Redemption
Price"):

         (b)  If the Series A Debentures are redeemed on any Interest Payment
Date, accrued and unpaid interest shall be payable to holders of record on the
relevant record date.

         (c)  If the Series A Debentures are redeemed after a record date and
on or before the related Interest Payment Date, accrued and unpaid interest
shall be payable to holders of record on the relevant record date.

         (d)  The Company shall not redeem any Series A Debentures unless all
accrued and unpaid interest thereon, including Compounded Interest and
Additional Interest, if any, has been paid in full for all quarterly interest
periods terminating prior to and including the redemption date.


                                          12

<PAGE>

         (e)  If the Company gives a notice of redemption in respect of
Series A Debentures (which notice will be irrevocable), then by 12:00 noon, New
York City time, on the redemption date, the Company shall deposit irrevocably
with the Trustee funds sufficient to pay the applicable Optional Redemption
Price and shall give irrevocable instructions and authority to pay such Optional
Redemption Price to the holders of the Series A Debentures.  If notice of
redemption shall have been given and funds deposited as required, then
immediately prior to the close of business on the redemption date interest shall
cease to accrue on the Series A Debentures called for redemption, such Series A
Debentures shall no longer be deemed to be outstanding and all rights of holders
of such Series A Debentures so called for redemption shall cease, except the
right of the holders of such Series A Debentures to receive the Optional
Redemption Price but without interest on such Optional Redemption Price.

         (f)  If any date fixed for redemption of any Series A Debentures is
not a Business Day, then payment of the Optional Redemption Price payable on
such date shall 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 calender 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 the Company fails to
repay the Series A Debentures on maturity or the date fixed for redemption or if
payment of the Optional Redemption Price in respect of the Series A Debentures
is improperly withheld or refused and not paid by the Company, interest on such
Series A Debentures shall continue to accrue from the original redemption date
to the date of payment, in which case the actual payment date shall be
considered the date fixed for redemption for purposes of calculating the
Optional Redemption Price.

         (g)  In the event of any redemption in part, the Company shall not be
required to (i) issue, register the transfer of or exchange any Series A
Debentures during a period beginning at the opening of business 15 days before
the mailing of a notice of redemption of Series A Debentures and ending at the
close of business on the date of such mailing and (ii) register the transfer of
or exchange any Series A Debentures so selected for redemption, in whole or in
part, except the unredeemed portion of any Series A Debentures being redeemed in
part.

         SECTION 3.02.  Optional Redemption upon the Occurrence of a Tax Event.

         If a Tax Event shall occur and be continuing, the Company shall have
the right within 90 days following the occurrence of such Tax Event to redeem
the Series A Debentures in whole, but not in part, for cash at the Tax
Redemption Price, together with any accrued and unpaid interest thereon,
including  Compounded Interest and Additional Interest, if any, to, but
excluding, the date of such redemption.

<PAGE>


         SECTION 3.03.  Partial Redemption.  If the Series A Debentures are
only partially redeemed pursuant to this Article Three, the Series A Debentures
will be redeemed pro rata or by lot or by any other method utilized by the
Trustee.  Notwithstanding the foregoing, if a partial redemption of the Series A
Debentures 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, the Company shall not be permitted to
effect such partial redemption and will only redeem the Series A Debentures in
whole.

         SECTION 3.04.  Corresponding Redemption of Preferred Securities.  So
long as the Preferred Securities are outstanding, the proceeds from the
redemption of the Series A Debentures will be used by Pogo Trust I to redeem
Preferred Securities having an aggregate liquidation amount equal to the
aggregate principal amount of the Series A Debentures so redeemed.

         SECTION 3.05.  Exchange of Preferred Securities for Series A
Debentures.

         (a)  At any time, the Company shall have the right to dissolve the
Trust and cause the Series A Debentures to be distributed to the holders of
the Preferred Securities in liquidation of Pogo Trust I after satisfaction of
liabilities to creditors of Pogo Trust I as provided by applicable law.

         (b)  If a Special Event in respect of Pogo Trust I shall occur, the
Company shall give the Property Trustee notice of the same. If a Special
Event in respect of Pogo Trust I shall occur and be continuing, the
Declaration of Trust requires the Property Trustee to direct the Conversion
Agent (as defined in the Declaration of Trust) to exchange all outstanding
Preferred Securities for the Series A Debentures having a principal amount
equal to the aggregate liquidation amount of the Preferred Securities to be
exchanged with accrued interest in an amount equal to any unpaid
distributions (including any Additional Interest) on the Preferred
Securities; PROVIDED, THAT, in the case of a Tax Event, the Company shall
have the right to direct the Property Trustee that less than all, or none of
the Preferred Securities be so exchanged (i) if and for so long as the
Company shall have elected to pay any Additional Interest such that the net
amounts received by holders of the Preferred Securities not so exchanged in
respect of 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) if the Company shall instead elect to redeem the Series A Debentures, in
whole or in part, in the manner set forth in Section 3.02.

                                     ARTICLE FOUR

                         Extension of Interest Payment Period

         SECTION 4.01.  Option to Extend Interest Payment Period.

         (a)  So long as no Event of Default has occurred and is continuing,
the Company shall have the right to defer payments of interest on the Series A
Debentures by extending the interest payment period of the Series A Debentures
at any time from time to time for up to 20 consecutive quarterly interest
periods (each such period an "Extended Interest Payment Period"), at the end of
which period the Company shall pay all interest accrued at the interest rate
specified in Section 2.05(a) herein compounded quarterly and unpaid thereon
(together with Compounded Interest and Additional Interest, if any); PROVIDED
THAT no Extended Interest Payment Period may extend beyond the Maturity Date or
redemption date of the Series A Debentures.

         (b)  During any Extended Interest Payment Period, the Company shall
not (i) declare or pay any dividends on, or redeem, purchase, acquire or make a
distribution or liquidation payment with respect to, any of its capital stock,
other than:

              (A)  dividends or distributions in shares of, or options,
                   warrants, rights to subscribe for or purchase shares of, the
                   Common Stock;


                                          14

<PAGE>

              (B)  any declaration of a dividend in connection with the
                   implementation of a shareholders' rights plan, or the
                   issuance of stock under any such plan in the future, or the
                   redemption or repurchase of any such rights pursuant
                   thereto;

              (C)  as a result of a reclassification of the Company's capital
                   stock or the exchange or the conversion of one class or
                   series of the Company's capital stock for another class or
                   series of the Company's capital stock;

              (D)  the payment of accrued dividends and the purchase of
                   fractional interests in shares of the Company's capital
                   stock pursuant to the conversion or exchange provisions of
                   such capital stock or the security being converted or
                   exchanged; or

              (E)  purchases of Common Stock related to the issuance of Common
                   Stock or rights under any of the Company's benefit plans for
                   its directors, officers, employees, any of the Company's
                   dividend reinvestment plans or stock purchase plans, or any
                   of the benefit plans of any of the Company's Affiliates for
                   such Affiliates' directors, officers or employees;

(ii)  make any payment of principal or of interest or premium, if any, on or
repay, repurchase or redeem any debt security of the Company that, ranks PARI
PASSU with or junior in interest to the Series A Debentures; or (iii) make any
guarantee payments with respect to any guarantee by the Company of the debt
securities of any Subsidiary of the Company (other than the Preferred Securities
Guarantee) if such guarantee ranks PARI PASSU with or junior in interest to the
Series A Debentures.

         (c)  Prior to the termination of any Extended Interest Payment Period,
the Company may pay all or any portion of the interest accrued on the Series A
Debentures on any Interest Payment Date to holders of record on the regular
record date for such Interest Payment Date or from time to time further extend
such Extended Interest Payment Period; PROVIDED that such Extended Interest
Payment Period together with all such further extensions thereof shall not
exceed 20 consecutive quarterly interest periods.  Upon the termination of any
Extended Interest Payment Period and the payment of all accrued and unpaid
interest, including any Additional Interest and Compounded Interest, the Company
may commence a new Extended Interest Payment Period, subject to the foregoing
requirements.  No interest shall be due and payable during an Extended Interest
Payment Period, except at the end thereof.  On the Interest Payment Date
occurring at the end of the Extended Interest Payment Period, the Company shall
pay all accrued and unpaid interest on the Series A Debentures, including any
Additional Interest and Compounded Interest,  to the holders of the Series A
Debentures in whose names the Series A Debentures are registered in the
Debenture Register


                                          15

<PAGE>

(regardless of who the holders of record may have been on other dates during the
Extended Interest Payment Period) on the record date for such Interest Payment
Date.

         SECTION 4.02.  Notice of Extension of Interest Payment Period.

         (a)  So long as the Property Trustee is the legal owner and sole
holder of record of the Series A Debentures, at the time the Company elects to
begin an Extended Interest Payment Period, the Company shall give both the
Property Trustee and the Trustee notice of its election to begin such Extended
Interest Payment Period one Business Day prior to the earlier of (i) the next
succeeding date on which Distributions (as defined in the Declaration of Trust)
on the Preferred Securities are payable or (ii) the date Pogo Trust I is
required to give notice of the record date or the date such Distributions are
payable to the New York Stock Exchange or other applicable self-regulatory
organization or to holders of the Preferred Securities, but in any event not
less than one Business Day prior to such record date.

         (b)  If as a result of a Dissolution Event Series A Debentures have
been distributed to holders of Trust Securities, the Company shall give the
holders of the Series A Debentures and the Trustee notice of its election to
begin an Extended Interest Payment Period at least 10 Business Days prior to the
earlier of (i) the next succeeding Interest Payment Date or (ii) the date the
Company is required to give notice of the record or payment date of such related
interest payment to the New York Stock Exchange (if the Series A Debentures are
then listed thereon) or other applicable self-regulatory organization or to
holders of the Series A Debentures.

         (c)  The quarter in which any notice is given pursuant to Section 4.02
shall not be counted as one of the quarters permitted in the maximum Extended
Interest Payment Period permitted under this Article Four.

                                     ARTICLE FIVE

               Conversion of the Series A Debentures into Common Stock

         SECTION 5.01.  Conversion Rights.

         Subject to and upon compliance with the provisions of this Article
Five, the Series A Debentures are convertible, at the option of the holder, at
any time prior to the Conversion Expiration Date, into fully paid and
nonassessable shares of Common Stock of the Company at an initial conversion
rate of 2.1053 shares of Common Stock for each $50 in aggregate principal amount
of Series A Debentures (equal to a conversion price of $23.75 per share of
Common Stock), subject to adjustment as described in this Article Five (as
adjusted the "Conversion Price").  A holder of Series A Debentures may convert
any portion of the principal amount of the Series A Debentures into that number
of fully paid and nonassessable shares of Common Stock (calculated as to each
conversion to the nearest 1/100th of a share)


                                          16

<PAGE>

obtained by dividing the principal amount of the Series A Debentures to be
converted by the Conversion Price.

         SECTION 5.02.  Conversion Procedures.

         (a)  NOTICE OF CONVERSION.  In order to convert all or a portion of
the Series A Debentures, the holder thereof shall deliver to the Property
Trustee, as conversion agent or to such other agent appointed by the Company for
such purposes (the "Conversion Agent") an irrevocable Notice of Conversion
setting forth the principal amount of Series A Debentures to be converted,
together with the name or names, if other than the holder, in which the shares
of Common Stock should be issued upon conversion and directing the Conversion
Agent to convert such Series A Debentures, on behalf of such holder into Common
Stock pursuant to the provisions of this Article Five, and, if such Series A
Debentures are definitive Series A Debentures, surrender to the Conversion Agent
the Series A Debentures to be converted, duly endorsed or assigned to the
Company or in blank.  In addition, a holder of Preferred Securities may exercise
its right under the Declaration of Trust to convert such Preferred Securities
into Common Stock by delivering to the Conversion Agent an irrevocable Notice of
Conversion setting forth the information called for by the preceding sentence
and directing the Conversion Agent (i) to exchange such Preferred Security for a
portion of the Series A Debentures held by the Trust (at an exchange rate of $50
principal amount of Series A Debentures for $50 liquidation amount Preferred
Security) and (ii) to immediately convert such Series A Debentures, on behalf of
such holder, into Common Stock pursuant to the provisions of this Article Five
and, if such Preferred Securities are in the form of Definitive Preferred
Security Certificates, surrendering such Definitive Preferred Security
Certificates, duly endorsed or assigned to the Company or in blank.

         If a Notice of Conversion is delivered after the close of business on
any regular record date and prior to the opening of business on the subsequent
Interest Payment Date, the holder of record on the regular record date shall be
entitled to receive the interest paid on the subsequent Interest Payment Date on
the portion of Series A Debentures to be converted notwithstanding the
conversion thereof prior to such Interest Payment Date.  Except as otherwise
provided in the immediately preceding sentence, in the case of any Debenture
which is converted, interest whose Interest Payment Date is on or after the date
of conversion of such Debenture shall not be payable, and the Company shall not
make nor be required to make any other payment, adjustment or allowance with
respect to accrued but unpaid interest on the Series A Debentures being
converted, which shall be deemed to be paid in full.

         (b)  CONVERSION DATE.  Each conversion shall be deemed to have been
effected immediately prior to the close of business on the day on which the
Notice of Conversion was received (the "Conversion Date") by the Conversion
Agent from the Holder or from a holder of the Preferred Securities effecting a
conversion thereof pursuant to its conversion rights under the Declaration of
Trust, as the case may be.  The Person or Persons entitled to receive the Common
Stock issuable upon such conversion shall be treated for all purposes as the


                                          17

<PAGE>

record holder or holders of such Common Stock as of the Conversion Date and such
Person or Persons will cease to be a record holder or record holders of the
Series A Debentures on that date.

         (c)  DELIVERY OF COMMON STOCK UPON CONVERSION.  As promptly as
practicable on or after the Conversion Date, the Company shall issue and deliver
at the office of the Conversion Agent, unless otherwise directed by the holder
or holders of the Preferred Securities identified in the Notice of Conversion, a
certificate or certificates for the number of full shares of Common Stock
issuable upon such conversion, together with the Fractional Share Cash Payment
Amount to the Person or Persons entitled to receive the same.  The Conversion
Agent shall deliver such certificate or certificates to such person or Persons.

         (d)  SATISFACTION OF OBLIGATIONS UNDER THE SERIES A DEBENTURES.  The
Company's delivery upon conversion of the fixed number of shares of Common Stock
into which the Series A Debentures are convertible (together with the cash
payment, if any, in lieu of fractional shares) shall be deemed to satisfy the
Company's obligation to pay the principal amount at maturity of the portion of
Series A Debentures so converted and any unpaid interest (including Additional
Interest and Compounded Interest, if any) accrued on such Series A Debentures at
the time of such conversion.

         (e)  CASH IN LIEU OF FRACTIONAL SHARES.  No fractional shares of
Common Stock will be issued as a result of conversion, but in lieu thereof, the
Company shall pay to the Conversion Agent a cash adjustment in an amount equal
to the same fraction of the Closing Price with respect to such fractional
interest on the Conversion Date (the "Fractional Share Cash Payment Amount"),
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, and the Conversion Agent in turn will make such
payment, if any, to the holder of the Series A Debentures or the holder of the
Preferred Securities so converted.

         (f)  ISSUANCE OF NEW DEBENTURES UPON PARTIAL CONVERSIONS.  In the
event of the conversion of any Debenture in part only, a new Debenture or
Series A Debentures for the unconverted portion thereof will be issued in the
name of the holder thereof upon the cancellation of the Debenture converted in
part in accordance with Section 2.04.

         (g)  ROLE AND AUTHORITY OF THE CONVERSION AGENT.  In effecting the
conversion transactions described in this Section, the Conversion Agent is
acting as agent of the holders of Preferred Securities (in the exchange of
Preferred Securities for Series A Debentures) and as agent of the holders of
Series A Debentures (in the conversion of Series A Debentures into Common
Stock), as the case may be, directing it to effect such conversion transactions.
The Conversion Agent is hereby authorized (i) to exchange Series A Debentures
held by the Trust from time to time for Preferred Securities in connection with
the conversion of such Preferred Securities in accordance with this Article Five
and (ii) to convert all or a portion of the Series A Debentures into Common
Stock and thereupon to deliver such shares of Common


                                          18

<PAGE>

Stock in accordance with the provisions of this Article Five and to deliver to
the Trust a new Debenture or Series A Debentures for any resulting unconverted
principal amount.

         (h)  COMMON STOCK TO BE ISSUED UPON CONVERSION OF SERIES A
DEBENTURES. The Company shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Series A Debentures, such number of shares of Common Stock
as shall from time to time be issuable upon the conversion of all the Series
A Debentures then outstanding.  Notwithstanding the foregoing, the Company
shall be entitled to deliver upon conversion of Series A Debentures shares of
Common Stock reacquired and held in the treasury of the Company (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. Whenever the Company issues shares of Common Stock
upon conversion of Series A 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. Any shares of Common Stock
issued upon conversion of the Series A 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 Series A
Debentures to the converting holder free and clear of all liens, charges,
security interests and encumbrances, except for United States withholding
taxes.  The Company 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 the Common Stock (and all requirements to
list the Common Stock issuable upon conversion of Series A Debentures that
are at the time applicable), in order to enable the Company to lawfully issue
Common Stock upon conversion of the Series A Debentures and to lawfully
deliver the Common Stock to each holder upon conversion of the Series A
Debentures.

         (i)  PAYMENT OF TAXES.  The Company shall 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 Series A Debentures.
The Company 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 Series A Debentures 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 Conversion
Agent that such tax has been paid.

         SECTION 5.03.  Conversion Price Adjustments.

         The Conversion Price shall be subject to adjustment (without
duplication) from time to time as follows:

         (a)  ADJUSTMENT UPON PAYMENT OF STOCK DIVIDENDS OR SUBDIVISIONS,
COMBINATIONS OR RECLASSIFICATIONS OF COMMON STOCK.  In case the Company shall,
while any of the Series A Debentures are outstanding, (i) pay a dividend or make
a distribution with respect to its Common Stock in shares of Common Stock, (ii)
subdivide its outstanding shares of Common Stock, (iii) combine its outstanding
shares of Common Stock into a smaller number of shares or (iv) issue by
reclassification of its shares of Common Stock any shares of capital stock of
the Company, the Conversion Price in effect immediately prior to such action
shall be adjusted by multiplying it by a fraction, the numerator of which is
equal to the total number of outstanding shares of Common Stock immediately
prior to such dividend, distribution, subdivision, combination or
reclassification, and the denominator of which is equal to the total number of
outstanding shares of Common Stock immediately following such dividend,
distribution, subdivision, combination or reclassification.

         An adjustment made pursuant to this subsection (a) shall become
effective immediately after the record date in the case of a dividend or other
distribution and shall become effective immediately after the effective date in
case of a subdivision, combination or reclassification (or immediately after the
record date if a record date shall have been established for such event).  If,
as a result of an adjustment made pursuant to this subsection (a), the holder of
any Debenture thereafter surrendered for conversion shall become entitled to
receive shares of two or more classes or series of capital stock of the Company,
the Board of Directors (whose determination shall be conclusive and shall be
described in a Board Resolution filed with the Trustee) shall determine the
allocation of the adjusted Conversion Price between or among shares of such
classes or series of capital stock.  In the event that such dividend,
distribution, subdivision, combination or issuance is not so paid or made, the
Conversion Price shall again be adjusted to be the Conversion Price which would
then be in effect if such record date had not been fixed.

         (b)  ADJUSTMENT UPON ISSUANCE OF RIGHTS OR WARRANTS TO ACQUIRE COMMON
STOCK AT PRICES BELOW MARKET VALUE.  In case the Company shall, while any of the
Series A Debentures are outstanding, issue rights or warrants to all holders of
its Common Stock entitling them (for a period expiring within 45 days after the
record date mentioned below) to subscribe for or purchase shares of Common Stock
at a price per share less than the Closing Price per share of Common Stock on
the record date mentioned below, the Conversion Price for the Series A
Debentures shall be adjusted so that the Conversion Price shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the date of issuance of such rights or warrants by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding on the date
fixed for the determination of stockholders entitled to receive such rights or
warrants plus the number of shares which the aggregate offering price


                                          20


<PAGE>

of the total number of shares so offered for subscription or purchase would
purchase at such Closing Price, and the denominator of which shall be the number
of shares of Common Stock outstanding on the date fixed for the determination of
stockholders entitled to receive such rights or warrants plus the number of
additional shares of Common Stock offered for subscription or purchase.  Such
adjustment shall become effective immediately after the record date for the
determination of stockholders entitled to receive such rights or warrants.  For
the purposes of this subsection, the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the Company.

         The Company agrees not to issue any rights or warrants in respect of
shares of Common Stock held in the treasury of the Company.

         In case any rights or warrants referred to in this subsection in
respect of which an adjustment shall have been made shall expire unexercised
within 45 days after the same shall have been distributed or issued by the
Company, the Conversion Price shall be readjusted at the time of such expiration
to the Conversion Price that would have been in effect if no adjustment had been
made on account of the distribution or issuance of such expired rights or
warrants.

         (c)  ADJUSTMENT UPON DISTRIBUTION OF EVIDENCES OF INDEBTEDNESS,
CAPITAL STOCK, CASH OR ASSETS.  Subject to the last sentence of this
subparagraph (c), in case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock evidences of its indebtedness,
shares of any class or series of capital stock, cash or assets (including
securities, but excluding (i) any rights or warrants referred to in
subparagraph (b), (ii) any dividend or distribution paid exclusively in cash
and (iii) any dividend or distribution referred to in subparagraph (a) of
this Section 5.03), the Conversion Price shall be reduced so that the
Conversion Price shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this subparagraph (c) by a
fraction, the numerator of which shall be the Closing Price per share of the
Common Stock on the date fixed for the payment of such distribution (the
"Reference Date") less the fair market value (as determined in good faith by
the Board of Directors, whose determination shall be conclusive and described
in a resolution of the Board of Directors filed with the Trustee), on the
Reference Date, of the portion of the evidences of indebtedness, shares of
capital stock, cash and assets so distributed applicable to one share of
Common Stock, and the denominator of which shall be such Closing Price per
share of the Common Stock, such reduction to become effective immediately
prior to the opening of business on the day following the Reference Date.

         In the event that such dividend or distribution is not so paid or
made, the Conversion Price shall again be adjusted to be the Conversion Price
which would then be in effect if such dividend or distribution had not occurred.
For purposes of this subparagraph (c), any dividend or distribution that
includes shares of Common Stock or rights or warrants to subscribe for or
purchase shares of Common Stock shall be deemed instead to be (i) a dividend or


                                          21

<PAGE>

distribution of the evidences of indebtedness, shares of capital stock, cash or
assets other than such shares of Common Stock or such rights or warrants (making
any Conversion Price reduction required by this subparagraph (c)) immediately
followed by (ii) a dividend or distribution of such shares of Common Stock or
such rights or warrants (making any further conversion price reduction required
by subparagraph (a) or (b)), except (A) the Reference Date of such dividend or
distribution as defined in this subparagraph shall be substituted as (x) "the
record date in the case of a dividend or other distribution," and (y) "the
record date for the determination of stockholders entitled to receive such
rights or warrants" and (z) "the date fixed for such determination" within the
meaning of subparagraphs (a) and (b) and (B) any shares of Common Stock included
in such dividend or distribution shall not be deemed outstanding for purposes of
computing any adjustment of the conversion price in subparagraph (a).

         (d)  ADJUSTMENT UPON ALL-CASH DISTRIBUTIONS.  In case the Company
shall pay or make a dividend or other distribution on its Common Stock
exclusively in cash (excluding (i) any cash dividends on Common Stock to the
extent that the aggregate cash dividends per share of Common Stock in any
consecutive 12-month period do not exceed the greater of (x) the amount per
share of Common Stock of the cash dividends paid on Common Stock in the
immediately preceding 12-month period, to the extent that such dividends for the
immediately preceding 12-month period did not require an adjustment of the
Conversion Price, and (y) 12.5% of the average of the daily Closing Prices of
the Common Stock for the ten consecutive trading days immediately prior to the
date of declaration of such dividend, and (ii) a redemption of any Rights issued
under a rights agreement), the Conversion Price shall be reduced so that the
Conversion Price shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to the effectiveness of the Conversion Price
reduction contemplated by this subparagraph (d) by a fraction, the numerator of
which shall be the Closing Price per share of the Common Stock on the date fixed
for the payment of such distribution less the amount of cash so distributed
(excluding that portion of such distribution that does not exceed 12.5% of the
Closing Price per share, determined as provided above) applicable to one share
of Common Stock and the denominator of which shall be such Closing Price per
share of the Common Stock, such reduction to become effective immediately prior
to the opening of business on the day following the date fixed for the payment
of such distribution; PROVIDED, HOWEVER, that in the event the portion of the
cash so distributed applicable to one share of Common Stock is equal to or
greater than the Closing Price per share of the Common Stock on the record date
mentioned above (excluding that portion of such distribution that does not
exceed 12.5% of the Closing Price per share, determined as provided above), in
lieu of the foregoing adjustment, adequate provision shall be made so that each
holder of  Series A Debentures shall have the right to receive upon conversion
the amount of cash such holder would have received had such holder converted
each of the Series A Debentures immediately prior to the record date for the
distribution of the cash (less that portion of such distribution that does not
exceed 12.5% of the Closing Price per share, determined as provided above).  In
the event that such dividend or distribution is not so paid


                                          22

<PAGE>

or made, the Conversion Price shall again be adjusted to be the conversion price
which would then be in effect if such record date had not been fixed.

         (e)  ADJUSTMENT UPON A TENDER OR EXCHANGE OFFER.  In case a tender
or exchange offer (other than an odd-lot offer) made by the Company or any
Subsidiary of the Company for all or any portion of the Common Stock shall
expire and such tender or exchange offer shall involve the payment by the
Company or such Subsidiary of consideration per share of Common Stock having
a fair market value (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a resolution of the
Board of Directors) at the last time (the "Expiration Time") tenders or
exchanges may be made pursuant to such tender or exchange offer (as it shall
have been amended) that exceeds 110% of the Closing Price of the Common Stock
on the trading day next succeeding the Expiration Time, the Conversion Price
shall be reduced so that the Conversion Price shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (e) by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding (including any tendered or exchanged
shares) at the Expiration Time (including the Purchased Shares) (as defined
below) multiplied by the Closing Price per share of the Common Stock on the
trading day next succeeding the Expiration Time and the denominator of which
shall be the sum of (x) the fair market value (determined as aforesaid) of
the aggregate consideration payable to stockholders based on the acceptance
(up to any maximum specified in the terms of the tender or exchange offer) of
all shares validly tendered or exchanged and not withdrawn as of the
Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "Purchased Shares") (excluding that portion of such
consideration in excess of the Closing Price per share that does not exceed
110% of the Closing Price per share) and (y) the product of the number of
shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the Closing Price per share of the Common Stock on the
trading day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following
the Expiration Time.  In the event that such tender or exchange offer is not
so made, the Conversion Price shall again be adjusted to be the Conversion
Price which would then be in effect if such record date had not been fixed.

         (f)  COMPANY'S OPTION TO REDUCE THE CONVERSION PRICE.  The Company
shall have the right to reduce from time to time the Conversion Price by any
amount selected by the Company for any period of at least 20 Business Days,
provided, that the Company shall give at least 15 days' notice of such reduction
to the Trustee and the holders of the Series A Debentures.  The Company may, at
its option, make such reductions in the Conversion Price, in addition to those
set forth above, as the Board of Directors deems advisable to avoid or diminish
any income tax to holders of Common Stock resulting from any dividend or
distribution of stock or issuance of rights or warrants to acquire stock or from
any event treated as such for tax purposes or for any other reasons.


                                          23

<PAGE>

         (g)  LIMITATION ON ADJUSTMENTS.  If any action would require
adjustment of the Conversion Price pursuant to more than one of the
anti-dilution provisions described above, only one adjustment shall be made and
such adjustment shall be the amount of adjustment that has the highest absolute
value to the holders of the Series A Debentures.  No adjustment in the
Conversion Price will be required unless such adjustment would require an
increase or decrease of at least 1% of the Conversion Price, but any adjustment
that would otherwise be required to be made shall be carried forward and taken
into account in any subsequent adjustment.

         SECTION 5.04.  Fundamental Change.

         (a)  In the event that the Company is a party to any transaction,
including, without limitation, a merger (other than a merger that does not
result in a reclassification, conversion, exchange or cancellation of Common
Stock), consolidation, sale of all or substantially all of the assets of the
Company, recapitalization or reclassification of Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination of Common Stock) or any
compulsory share exchange (each of the foregoing being referred to as a
"Transaction"), in each case, as a result of which shares of Common Stock shall
be converted into the right to receive, or shall be exchanged for, (i) in the
case of any Transaction other than a Transaction involving a Common Stock
Fundamental Change (and subject to funds being legally available for such
purpose under applicable law at the time of such conversion), securities, cash
or other property, each Debenture shall thereafter be convertible into the kind
and, in the case of a Transaction which does not involve a Fundamental Change,
amount of securities, cash and other property receivable upon the consummation
of such Transaction by a holder of that number of shares of Common Stock into
which a Debenture was convertible immediately prior to such Transaction, or (ii)
in the case of a Transaction involving a Common Stock Fundamental Change, common
stock, each Debenture shall thereafter be convertible (in the manner described
herein) into common stock of the kind received by holders of Common Stock (but
in each case after giving effect to any adjustment discussed in paragraphs (b)
and (c) below relating to a Fundamental Change if such Transaction constitutes a
Fundamental Change).  The holders of Series A Debentures or Preferred Securities
will have no voting rights with respect to any Transaction described in this
section.

         (b)  If any Fundamental Change occurs, then the Conversion Price in
effect will be adjusted immediately after such Fundamental Change as described
in paragraph (c) below.  In addition, in the event of a Common Stock Fundamental
Change, each Debenture shall be convertible solely into common stock of the kind
received by holders of Common Stock as a result of such Common Stock Fundamental
Change.

         (c)  The Conversion Price in the case of any Transaction involving a
Fundamental Change will be adjusted immediately after such Fundamental Change
such that:


                                          24

<PAGE>

              (1)  in the case of a Non-Stock Fundamental Change, the
         Conversion Price of the Series A Debentures will thereupon become the
         lower of (A) the Conversion Price in effect immediately prior to such
         Non-Stock Fundamental Change, but after giving effect to any other
         prior adjustments, and (B) the result obtained by multiplying the
         greater of the Applicable Price or the then applicable Reference
         Market Price by a fraction, the numerator of which shall be $50 and
         the denominator of which shall be (x) the amount of the Optional
         Redemption Price for the Debenture if the redemption date were the
         date of such Non-Stock Fundamental Change (or, for the period
         commencing on the first date of original issuance of the Series A
         Debentures and through May 31, 2000, and the twelve-month periods
         commencing June 1, 2000 and June 1, 2001, the product of 106.50%,
         105.85% and 105.20%, respectively, multiplied by $50) plus (y) any
         then-accrued and unpaid interest on the Series A Debentures; and

              (2)  in the case of a Common Stock Fundamental Change, the
         Conversion Price of the Series A Debentures in effect immediately
         prior to such Common Stock Fundamental Change, but after giving effect
         to any other prior adjustments, will thereupon be adjusted by
         multiplying such Conversion Price by a fraction, the numerator of
         which shall be the Purchaser Stock Price and the denominator shall be
         the Applicable Price; provided, however, that in the event of a Common
         Stock Fundamental Change in which (A) 100% of the value of the
         consideration received by a holder of Common Stock is common stock of
         the successor, acquirer, or other third party (and cash, if any, is
         paid only with respect to any fractional interests in such common
         stock resulting from such Common Stock Fundamental Change) and (B) all
         of the Common Stock will have been exchanged for, converted into, or
         acquired for common stock (and cash with respect to fractional
         interests) of the successor, acquirer, or other third party, the
         Conversion Price of the Series A Debentures in effect immediately
         prior to such Common Stock Fundamental Change will thereupon be
         adjusted by multiplying such Conversion Price by a fraction, the
         numerator of which shall be one and the denominator of which shall be
         the number of shares of common stock of the successor, acquirer, or
         other third party received by a holder of one share of Common Stock as
         a result of such Common Stock Fundamental Change.

         SECTION 5.05.  Notice of Adjustments of Conversion Price.

         Whenever the Conversion Price is adjusted as herein provided:

         (a)  the Company shall compute the adjusted conversion price and shall
prepare a certificate signed by the Chief Financial Officer and the Controller
of the Company setting forth the adjusted conversion price and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed with the Trustee, the Conversion Agent and
the Debenture Registrar; and


                                          25

<PAGE>

         (b)  a notice stating the Conversion Price has been adjusted and
setting forth the adjusted Conversion Price shall as soon as practicable be
mailed by the Company to all record holders of the Series A Debentures at their
last addresses as they appear upon the Debenture Register.

         SECTION 5.06.  Dividend or Interest Reinvestment Plans.

         Notwithstanding anything to the contrary in this Article Five, no
adjustment of the Conversion Price will be made upon the issuance of any shares
of Common Stock pursuant to any present or future plan providing for the
reinvestment of dividends or interest payable on securities of the Company.  The
investment of additional optional amounts in shares of Common Stock under any
such plan, and the issuance of any shares of Common Stock or options or rights
to purchase such shares pursuant to any employee benefit plan or program of the
Company or any of its Subsidiaries or joint ventures currently existing or
adopted subsequent to May 26, 1999 or pursuant to any option, warrant, right or
exercisable, exchangeable or convertible security outstanding as of the date the
Series A Debentures were first issued, shall not be deemed to constitute an
issuance of Common Stock or exercisable, exchangeable or convertible securities
by the Company to which any of the adjustment provisions described above
applies.  There shall also be no adjustment of the Conversion Price in case of
the issuance of any stock (or securities convertible into or exchangeable for
stock) of the Company except as specifically described in this Article Five.


         SECTION 5.07.  Trustee Not Responsible for Determining Conversion
Price or Adjustments.

         Neither the Trustee nor any Conversion Agent shall at any time be
under any duty or responsibility to any holder of any Debenture or to any holder
of a Preferred Security to determine whether any facts exist which may require
any adjustment of the Conversion Price, or with respect to the nature or extent
of any such adjustment when made, or with respect to the method employed, or
herein or in any supplemental indenture provided to be employed, in making the
same or whether a supplemental indenture need be entered into.  Neither the
Trustee nor any Conversion Agent shall be accountable with respect to the
validity or value (or the kind of account) of any shares of Common Stock or of
any securities or property, which may at any time be issued or delivered upon
the conversion of any Debenture; and neither the Trustee nor any Conversion
Agent makes any representation with respect thereto.  Neither the Trustee nor
any Conversion Agent shall be responsible for any failure of the Company to make
any cash payment or to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property upon the surrender of any
Debenture for the purpose of conversion, or, except as expressly herein
provided, to comply with any of the covenants of the Company contained in this
Article Five.

in shares of, or options, warrants, rights to subscribe for or purchase shares
of, common stock of the Company, (b) any declaration of a dividend in connection

ranks PARI PASSU with or junior in interest to the Series A Debentures or (iii)
make any guarantee payments with respect to any guarantee by the Company of the
debt securities of any Subsidiary of the Company (other than pursuant to the
Preferred Securities Guarantee or a substantially similar guarantee agreement
relating to a series of trust preferred securities substantially similar to the

default with respect to its Guarantee Payments (as defined in the Preferred
Securities Guarantee) or other payment obligations under the Preferred
Securities Guarantee, (y) there shall have occurred any Event of Default with
respect to the Series A Debentures or (z) the Company shall have given notice of

distribution of the Series A Debentures to the holders of the Preferred

list such Series A Debentures on the New York Stock Exchange or on such other
exchange or quotation system as the Preferred Securities are then listed and
traded.

         SECTION 6.03.  Compliance With the Declaration of Trust.  The Company
covenants and agrees for the benefit of the holders of the Preferred Securities
to comply fully with all


                                          27

<PAGE>

of its obligations and agreements under the Declaration of Trust, including,
without limitation, its obligations under Article 4 thereof.

         SECTION 6.04.  Covenants With Respect to Pogo Trust I.  Prior to the

Common Securities to be transferred except as permitted by the Declaration of
Trust, provided that any permitted successor of the Company under the Indenture
may succeed to the Company's ownership of the Common Securities, and (ii) use
reasonable efforts to cause Pogo Trust I to continue to be treated as a grantor
trust for United States federal income tax purposes, except in connection with a
Dissolution Event.

6 1/2% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURE, SERIES A DUE 2029

         POGO PRODUCING COMPANY, a corporation duly organized and existing
under the laws of the State of Delaware (herein referred to as the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to _________________
_______, or registered assigns, the principal sum of _________ Dollars on
June 1, 2029, PROVIDED, if a Tax Event occurs, then the Company will have the
right (a) prior to the dissolution of Pogo Trust I, to shorten the Maturity Date
of this series of Debentures to the minimum extent required, but not earlier
than June 2, 2014, or (b) to direct the Property Trustee to dissolve Pogo Trust
I (if not previously dissolved) and shorten the Maturity Date of this series of
Debentures to the minimum extent required, but not earlier than June 2, 2014, in
each case such that in the opinion of counsel to the Company, experienced in
such matters, after shortening the Maturity Date, interest paid on this
series of Debentures will be deductible for federal income tax purposes, and to
pay interest on said principal sum from June 2, 1999 or from the most recent
interest payment date (each such date, an "Interest Payment Date") to which
interest has been paid or duly provided for, quarterly in arrears on March 1,
June 1, September 1 and December 1 of each year, commencing September 1, 1999 at
the rate of 6 1/2% per annum plus Additional Interest and Compounded Interest,
if any, until the principal hereof shall have become due and payable, and on
any overdue principal and premium, if any.

         So long as no Event of Default has occurred and is continuing, the
Company shall have the right to defer payments of interest on this series of
Debentures by extending the interest payment period of this series of Debentures
at any time from time to time for up to 20 consecutive quarterly interest
periods (each such period an "Extended Interest Payment Period"), at the end of
which period the Company shall pay all interest accrued and unpaid thereon
(together with Compounded Interest and Additional Interest, if any); PROVIDED
THAT no Extended Interest Payment Period may extend beyond the Maturity Date or
redemption date of this series of Debentures.  Prior to the termination of any
Extended Interest Payment Period, the Company may pay all or any portion of the
interest accrued on this series of Debentures on any Interest Payment Date to
holders of record on the regular record date for such Interest Payment Date or
prepay at any time all or any portion of the interest accrued during an
Extension Period or from time to time further extend such Extended Interest
Payment Period; PROVIDED THAT such Extended Interest Payment Period together
with all such further extensions thereof shall not exceed 20 consecutive
quarterly interest periods or extend beyond the Maturity Date or redemption date
of this series of Debentures.  Upon the termination of any Extended Interest
Payment Period and the payment of all accrued and


                                          29

<PAGE>

unpaid interest, including any Additional Interest and Compounded Interest, the
Company may commence a new Extended Interest Payment Period, subject to the
foregoing requirements.  No interest shall be due and payable during an Extended
Interest Payment Period, except at the end thereof.  On the Interest Payment
Date occurring at the end of the Extended Interest Payment Period, the Company
shall pay all accrued and unpaid interest on this series of Debentures,
including any Additional Interest and Compounded Interest,  to the holders of
this series of Debentures in whose names this series of Debentures are
registered in the Debenture Register (regardless of who the holders of record
may have been on other dates during the Extended Interest Payment Period) on the
record date for such Interest Payment Date.

         The amount of interest payable on any Interest Payment Date shall be
computed on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly interest period for which interest is
computed, interest shall be computed on the basis of the actual number of days
elapsed per 90-day quarter.  In the event that any date on which interest is
payable on this series of Debentures is not a Business Day, then payment of
interest payable on such date shall be made on the next succeeding day which is
a Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date such payment was
originally payable.  The interest installment so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the person in whose name this Debenture (or one or more
Predecessor Debentures, as defined in said Indenture) is registered at the close
of business on the regular record date for such interest installment, [IF POGO
TRUST I OR ITS PROPERTY TRUSTEE IS THE HOLDER OF RECORD OF THIS DEBENTURE --
which shall be the close of business on the Business Day next preceding such
Interest Payment Date, provided if the Preferred Securities of Pogo Trust I are
no longer in book-entry only form, the regular record dates shall be the close
of business on the fifteenth (15th) day of the month in which such Interest
Payment Date occurs] [IF PURSUANT TO THE PROVISIONS OF SECTION 2.11(c) OF THE
INDENTURE THIS series of Debentures IS NOT REPRESENTED BY A GLOBAL DEBENTURE --
which shall be the close of business on the fifteenth (15th) day of the month in
which such Interest Payment Date occurs.]  Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to the
registered holders on such regular record date, and shall instead be paid to the
person in whose name this Debenture (or one or more Predecessor Debentures) is
registered at the close of business on a special record date to be fixed by the
Trustee for the payment of such defaulted interest, notice whereof shall be
given to the registered holders of this series of Debentures not less than 10
days prior to such special record date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
or quotation system on which the Debentures of this series may be listed or
traded, and upon such notice as may be required by such exchange or quotation
system, all as more fully provided in Section 2.03 of the Indenture.  The
principal of and the interest on this


                                          30

<PAGE>

Debenture shall be payable at the Corporate Trust Office of the Trustee, in any
coin or currency of the United States of America which at the time of payment is
legal tender for payment of public and private debts; PROVIDED, HOWEVER, that
payment of interest may be made at the option of the Company by check mailed to
the registered holder at such addresses as shall appear in the Debenture
Register and that the payment of principal will only be made upon the surrender
of this Debenture to the Trustee.  Notwithstanding the foregoing, so long as the
owner and record holder of this Debenture is the Property Trustee (as defined in
the Indenture), the payment of the principal of and interest (including
Additional Interest and Compounded Interest, if any) on this Debenture will be
made by the Company in immediately available funds on the payment date therefor
at such place and to the Property Account (as defined in the Indenture)
established and maintained by the Property Trustee pursuant to the Declaration
of Trust (as defined in the Indenture).

         The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Debt (as defined in the Indenture), and this
Debenture is issued subject to the provisions of the Indenture with respect
thereto.  Each holder of this Debenture, by accepting the same, (a) agrees to
and shall be bound by such provisions, (b) authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to acknowledge
or effectuate the subordination so provided and (c) appoints the Trustee his
attorney-in-fact for any and all such purposes.  Each holder hereof, by his
acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of
Senior Debt, whether now outstanding or hereafter incurred, and waives reliance
by each such holder upon said provisions.

         This Debenture shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any purpose
until the Certificate of Authentication hereon shall have been signed by or on
behalf of the Trustee.

         The provisions of this Debenture are continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

                       (FORM OF REVERSE OF SERIES A DEBENTURE)

         This Debenture is one of a duly authorized series of Debentures of the
Company (herein sometimes referred to as the "Debentures"), specified in the
Indenture, all issued or to be issued in one or more series under and pursuant
to an Indenture dated as of June 1, 1999 duly executed and delivered between the
Company and Wilmington Trust Company, a Delaware banking corporation, as Trustee
(herein referred to as the "Trustee"), as supplemented by the Supplemental
Indenture No. 1 dated as of June 1, 1999 ("Supplemental Indenture No. 1")
between the Company and the Trustee (said Indenture as so supplemented being
hereinafter referred to as the "Indenture"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the holders of the Debentures, and, to the
extent specifically set forth in the Indenture, the holders of Senior Debt and
Preferred Securities.  By the terms of the Indenture, the Debentures are
issuable in series which may vary as to amount, date of maturity, rate of
interest and in other respects as in the Indenture provided.  This series of
Debentures is designated the 6 1/2% Junior Subordinated Convertible Debentures,
Series A due 2029 and is limited in aggregate principal amount as specified in
said Supplemental Indenture No. 1.

         Except as provided in the next paragraph, the Debentures of this
series shall not be redeemed by the Company prior to June 1, 2002.  The Company
shall have the right to redeem this Debenture at the option of the Company, in
whole or in part, at any time from time to time on or after June 1, 2002 (an
"Optional Redemption"), upon not less than 30 nor more than 60 days' notice to
the holders of the Debentures of this series, during the twelve-month periods
commencing June 1 in each of the following years at the indicated redemption
price (expressed as a percentage of the principal amount of the Series A
Debentures being redeemed), together with any accrued but unpaid interest
thereon, including Compounded Interest and Additional Interest, if any, to, but
excluding, the date of such redemption (the "Optional Redemption Price"):

<PAGE>

         The Company shall not redeem any Debentures of this series unless all
accrued and unpaid interest thereon, including Compounded Interest and
Additional Interest, if any, has been paid for all quarterly interest periods
terminating on or prior to the date of notice of redemption.

         If a Special Event shall occur and be continuing, this Series A
Debenture shall be exchangeable for Preferred Securities in accordance with
Section 3.05 of the Indenture or, in certain circumstances, redeemable by the
Company in accordance with Section 3.02 of the Indenture.

         If a Tax Event shall occur or be continuing, the Company shall have
the right at any time to redeem the Debentures of this series in whole, but not
in part, for cash at the Tax Redemption Price, together with any accrued unpaid
interest thereon, including Compounded Interest and Additional Interest, if any,
to but excluding the date of such redemption within 90 days following the
occurrence of such Tax Event.

         "Tax Event" means that the Company and the Regular Trustees shall
have received an opinion of nationally recognized independent 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 the theretofore
generally accepted position or (d) any action taken by any governmental
agency or regulatory authority, which amendment or change is enacted,
promulgated, issued or 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 than a remote risk that (i) Pogo Trust I is, or
will be within 90 days of the date thereof, subject to federal income tax
with respect to income accrued or received on the Debentures of this series,
(ii) Pogo Trust I 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 the Company to Pogo Trust I on the
Debentures of this series is not, or within 90 days of the date thereof will
not be, deductible by the Company for federal income tax purposes;

                                          34

<PAGE>

         "Tax Redemption Price" means with respect to each $50 principal
amount of Series A Debentures (i) if the Series A Debentures are redeemed as
a result of the occurrence of a Tax Event prior to June 1, 2002, the greater
of (a) the total principal amount of such Series A Debenture or the
liquidation amount of the Preferred Securities, (b) the average of the
highest and lowest reported sale prices, regular way, of the Preferred
Securities over the five trading days immediately prior to the day on which
notice of such redemption is given, and (c) the average of the highest and
lowest reported sale prices, regular way, of Preferred Securities on the
trading day immediately prior to the day on which notice of such redemption
is given, or (ii) if the Series A Debentures are redeemed as a result of the
occurrence of a Tax Event on or after June 1, 2002, the principal amount of
such Series A Debentures. For purposes of clauses (b) and (c) above, if the
Series A Debentures have been distributed in exchange for Preferred
Securities, the references to sales prices shall be deemed to refer to the
sales price, of the Series A Debentures.

         If the Debentures of this series are only partially redeemed by the
Company pursuant to an Optional Redemption, the Debentures shall be redeemed pro
rata or by lot or in some other equitable manner determined by the Trustee;
provided if, at the time of redemption, the Debentures of this series are
registered as a Global Debenture, the Depository shall determine the principal
amount of such Debentures of this series held by each holder of Debentures to be
redeemed in accordance with its customary procedures.  Notwithstanding the
foregoing, if a partial redemption of the Debentures of this series 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, the Company shall not be permitted to effect such partial redemption and
will only redeem the Debentures of this series in whole.

         In the event of redemption of this Debenture in part only, a new
Debenture or Debentures of this series for unredeemed portion hereof will be
issued in the name of the holder hereof upon the cancellation hereof.

         Subject to the terms and conditions set forth in Article V of
Supplemental Indenture No. 1, this Debenture is convertible, at the option of
the holder hereof, into shares of Common Stock upon delivery by such holder to
the Conversion Agent of an irrevocable Notice of Conversion [IF DEBENTURE ISSUED
IN CERTIFICATED FORM -- and, surrender to the Conversion Agent by such holder of
this Debenture, duly endorsed or assigned to the Company in a blank.] In
addition a holder of Preferred Securities may exercise its right under the
Declaration of Trust to convert such Preferred Securities into Common Stock by
delivering to the Conversation Agent an irrevocable Notice of Conversion
directing


                                          35

<PAGE>

the Conversion Agent (i) to exchange such Preferred Security for the portion of
this Debenture held by the Trust and (ii) to immediately convert such portion of
this Debenture, on behalf of such holder, into Common Stock, and if such
Preferred Securities are in the form of Definitive Preferred Security
Certificates, surrendering such Definitive Preferred Security Certificates, duly
endorsed or assigned to the Company or in blank.  A form of Notice of Conversion
is included at the end of this Debenture.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Debentures of this
series may be declared, and upon such declaration shall become, due and payable,
in the manner, with the effect and subject to the conditions provided in the
Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Debentures of each series affected at the time
outstanding, as defined in the Indenture (and, if this Debenture is held as a
trust asset of Pogo Trust I, such consent of holders of the Preferred Securities
and the Common Securities as may be required under the Declaration of Trust), to
execute supplemental indentures for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of the Indenture or
of any supplemental indenture or of modifying in any manner the rights of the
holders of the Debentures; PROVIDED, HOWEVER, that no such supplemental
indenture shall (i) extend the fixed maturity of the Debentures of this series,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Debenture so affected or (ii)
reduce the aforesaid percentage of Debentures, the holders of which are required
to consent to any such supplemental indenture, without the consent of the
holders of each Debenture (and, if this Debenture is held as a trust asset of
Pogo Trust I, such consent of the holders of the Preferred Securities and the
Common Securities as may be required under the Declaration of Trust) then
outstanding and affected thereby.  The Indenture also contains provisions
permitting the holders of a majority in aggregate principal amount of the
Debentures of a series at the time outstanding affected thereby (subject, in the
case of a Debenture held as a trust asset of Pogo Trust I and with respect to
which a securities exchange has not theretofore occurred, to such consent of
holders of Preferred Securities and Common Securities as may be required under
the Declaration of Trust), on behalf of the holders of the Debentures of such
series, to waive any past default in the performance of any of the covenants
contained in the Indenture, or established pursuant to the Indenture with
respect to such series, and its consequences, except a default in the payment of
the principal of or premium, if any, or interest on any of the Debentures of
such series as and when the same shall become due by the terms of the Debentures
of such series otherwise than by acceleration (unless such default


                                          36

<PAGE>

has been cured and a sum sufficient to pay all matured installments of interest
and principal and any premium has been deposited with the Trustee), or a call
for redemption of the Debentures of such series.  Any such consent or waiver by
the registered holder of this Debenture (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such holder and upon all future
holders and owners of this Debenture and of any Debenture issued in exchange
herefor or in place hereof (whether by registration of transfer or otherwise),
irrespective of whether or not any notation of such consent or waiver is made
upon this Debenture.

         Subject to Section 13.11 of the Indenture, no reference herein to the
Indenture (other than such Section) and no provision of this Debenture or of the
Indenture shall alter or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of and interest on this Debenture at the
time and place at the rate and in the money herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, this Debenture is transferable by the registered holder
hereof on the Debenture Register, upon surrender of this Debenture for
registration of transfer at the Corporate Trust Office of the Trustee
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company or the Trustee duly executed by the registered
holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Debentures of authorized denominations and for the same aggregate
principal amount and series will be issued to the designated transferee or
transferees.  No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

         Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any paying agent and any Debenture
Registrar may deem and treat the registered holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and notwithstanding any
notice of ownership or writing hereon made by anyone other than the Debenture
Registrar) for the purpose of receiving payment of or on account of the
principal hereof and interest due hereon and for all other purposes, and neither
the Company nor the Trustee nor any paying agent nor any Debenture Registrar
shall be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, shareholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

Holders, as applicable, such documents, reports and information as required
by Section 314(a)(1)-(3) (if any) of the Trust Indenture Act and the
compliance certificates required by Section 314(a)(4) and (c) of the Trust

days of the end of each fiscal year of the Guarantor).

         SECTION 2.05. EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT. The

<PAGE>

Default and its consequences. Upon such waiver, any such Event of Default
shall cease to exist, and any Event of Default arising therefrom shall be
deemed to have been cured, for every purpose of this Guarantee Agreement, but
no such waiver shall extend to any subsequent or other default or Event of
Default, or impair any right consequent thereon.

           (b) The right of any Holder to receive payment of the Guarantee
Payments in accordance with this Guarantee Agreement, or to institute suit for

of each such Holder.

as to the names and addresses of the Holders in accordance with Section 312 of
the Trust Indenture Act, regardless of the source from which such information

law hereafter enacted which does not specifically refer to Section 312 of the
Trust Indenture Act, nor shall the Guarantee Trustee be held accountable by
reason of mailing any material pursuant to a request made under Section 312(b)
of the Trust Indenture Act.

         SECTION 2.08. CONFLICTING INTEREST. The Declaration shall be deemed to

                                    ARTICLE 3
               POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

         SECTION 3.01. POWERS AND DUTIES OF THE GUARANTEE TRUSTEE. (a) This
Guarantee Agreement shall be held by the Guarantee Trustee in trust for the
benefit of the Holders. The Guarantee Trustee shall not transfer its right,
title and interest in this Guarantee Agreement to any Person except a Successor
Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its
appointment to act as Guarantee Trustee or to a Holder exercising his or her
rights pursuant to Section 5.04(iv). The right, title and interest of the
Guarantee Trustee to this Guarantee Agreement shall vest automatically in each
Person who may hereafter be appointed as Guarantee Trustee in accordance with
Article 4. Such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered.

           (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the
Holders.

           (c) This Guarantee Agreement and all moneys received by the Property
Trustee in respect of the Guarantee Payments 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 Guarantee Trustee or its agents or their creditors.

           (d) The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default known to a Responsible Officer of the Guarantee Trustee,
transmit by mail, first class postage prepaid, to the Holders, as their names
and addresses appear upon the List of Holders, notice of all such Events of
Default, unless such defaults shall have been cured before the giving of such
notice; PROVIDED, that, the Guarantee 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

                                       6
<PAGE>

Officers, of the Guarantee Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders. The Guarantee
Trustee shall not be deemed to have knowledge of any Event of Default except
any Event of Default as to which the Guarantee Trustee shall have received
written notice or a Responsible Officer charged with the administration of
this Guarantee Agreement shall have obtained written notice of such Event of
Default.

           (e) The Guarantee Trustee shall continue to serve as a trustee until
a Successor Guarantee Trustee has been appointed and accepted that appointment
in accordance with Article 4.

         SECTION 3.02.  CERTAIN RIGHTS AND DUTIES OF THE GUARANTEE TRUSTEE.
(a)  The Guarantee Trustee, before the occurrence of an Event of Default and
after the curing or waiving of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee.  In case an Event of
Default has occurred (that has not been cured or waived pursuant to Section
2.06), the Guarantee Trustee shall exercise such of the rights and powers
vested in it by this Guarantee Agreement, and use the same degree of care and
skill in its exercise thereof, 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 Guarantee Agreement shall be construed to
relieve the Guarantee 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 Guarantee Trustee
                  shall be determined solely by the express provisions of this
                  Guarantee Agreement, and the Guarantee Trustee shall not be
                  liable except for the performance of such duties and
                  obligations as are specifically set forth in this Guarantee
                  Agreement, and no implied covenants or obligations shall be
                  read into this Guarantee Agreement against the Guarantee
                  Trustee; and

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

          (ii) the Guarantee Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer of the Guarantee
         Trustee, unless it shall be proved that


                                       7

<PAGE>


         the Guarantee Trustee was negligent in ascertaining the pertinent facts
         upon which such judgment was made;

           (iii) the Guarantee 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 a Majority in liquidation amount
         of Preferred Securities relating to the time, method and place of
         conducting any proceeding for any remedy available to the Guarantee
         Trustee, or exercising any trust or power conferred upon the Guarantee
         Trustee under this Guarantee Agreement; and

           (iv)  no provision of this Guarantee Agreement shall require the
         Guarantee 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
         Guarantee Agreement or adequate indemnity against such risk or
         liability is not reasonably assured to it.

         (c) Subject to the provisions of Section 3.02(a) and (b):

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

           (ii)  the Guarantee Trustee (A) may consult with counsel (which may
         be counsel to the Guarantor 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 Guarantee Agreement
         from any court of competent jurisdiction;

           (iii) the Guarantee 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 Guarantee 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 Guarantee Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Guarantee Agreement at
         the request or direction of any Holder, unless such Holder shall have
         offered to the Guarantee Trustee security and indemnity satisfactory to
         the Guarantee Trustee against the costs, expenses (including its
         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 Guarantee

                                      8
<PAGE>



         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 Guarantee Agreement, 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 Guarantee Trustee or its agents
         hereunder shall bind the Holders and the signature of the Guarantee
         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 Guarantee Trustee to so act, or as
         to its compliance with any of the terms and provisions of this
         Guarantee Agreement, both of which shall be conclusively evidenced by
         the Guarantee Trustee's or its agent's taking such action.

         SECTION 3.03. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE.
The recitals contained in this Guarantee Agreement shall be taken as the
statements of the Guarantor and the Guarantee Trustee does not assume any
responsibility for their correctness. The Guarantee Trustee makes no
representations as to the validity or sufficiency of this Guarantee Agreement.

         SECTION 3.04. THE GUARANTEE TRUSTEE MAY OWN PREFERRED SECURITIES. The
Guarantee Trustee, in its individual or any other capacity, may become the owner
or pledgee of Preferred Securities and may otherwise deal with the Guarantor
with the same rights it would have if it were not Guarantee Trustee.

         SECTION 3.05. MONEYS RECEIVED BY THE GUARANTEE TRUSTEE TO BE HELD IN
TRUST WITHOUT INTEREST. All moneys received by the Guarantee 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 Guarantee 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.


                                    ARTICLE 4
                                GUARANTEE TRUSTEE

         SECTION 4.01.  QUALIFICATIONS.  There shall at all times be a Guarantee
Trustee that shall:

           (i)  not be an Affiliate of the Guarantor; and

           (ii) be a national banking association or corporation 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 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 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
         clause (ii), the combined capital and surplus of such corporation shall

                                      9
<PAGE>

         be deemed to be its combined capital and surplus as set forth in its
         most recent report of condition so published.

         If at any time the Guarantee Trustee shall cease to satisfy the
requirements of clauses (i) and (ii) above, the Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section 4.02. If
the Guarantee Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Guarantee Trustee and
the Guarantor shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act.

         SECTION 4.02.  APPOINTMENT, REMOVAL AND RESIGNATION OF THE GUARANTEE
TRUSTEE. (a)  Subject to Section 4.02(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed in accordance with
Section 4.02(a) until a Successor Guarantee Trustee possessing the
qualifications to act as Guarantee Trustee under Section 4.01 has been appointed
and has accepted such appointment by written instrument executed by such
Successor Guarantee Trustee and delivered to the Guarantor and the Guarantee
Trustee being removed.

         (c) The Guarantee Trustee appointed to office shall hold office until
his successor shall have been appointed or until its removal or resignation.

         (d) The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument (a "Resignation Request") in
writing signed by the Guarantee Trustee and delivered to the Guarantor, which
resignation shall take effect upon such delivery or upon such later date as is
specified therein; PROVIDED, HOWEVER, that no such resignation of the Guarantee
Trustee shall be effective until a Successor Guarantee Trustee possessing the
qualifications to act as Guarantee Trustee under Section 4.01 has been appointed
and has accepted such appointment by instrument executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (e) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.02 within 60 days after
delivery to the Guarantor of a Resignation Request, the resigning Guarantee
Trustee may petition any court of competent jurisdiction for appointment of a
Successor Guarantee Trustee. Such court may thereupon after such notice, if any,
as it may deem proper and prescribe, appoint a Successor Guarantee Trustee.


                                    ARTICLE 5
                                    GUARANTEE

         SECTION 5.01. GUARANTEE. To the extent set forth herein, the Guarantor
irrevocably and unconditionally agrees to pay in full to the Holders the
Guarantee Payments (without duplication of amounts theretofore paid by the
Issuer), as and when due, regardless of any defense, right of set-off or
counterclaim which the Issuer may have or assert. The Guarantor's obligation to
make a Guarantee Payment may be satisfied by direct payment of the required
amounts by the Guarantor to the Holders or by causing the Issuer to pay such
amounts to the Holders.

                                      10
<PAGE>

         SECTION 5.02. WAIVER OF NOTICE. The Guarantor hereby waives notice of
acceptance of this Guarantee Agreement and of any liability to which it applies
or may apply, presentment, demand for payment, any right to require a proceeding
first against the Issuer or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands. Notwithstanding anything to the
contrary herein, the Guarantor retains all of its rights under the Indenture to
extend the interest payment period on the Debentures and the Guarantor shall not
be obligated hereunder to make any Guarantee Payment during any Extended
Interest Payment Period (as defined in the Supplemental Indenture) with respect
to the Distributions on the Preferred Securities.

         SECTION 5.03. OBLIGATIONS NOT AFFECTED. The obligations, covenants,
agreements and duties of the Guarantor under this Guarantee Agreement shall in
no way be affected or impaired by reason of the happening from time to time of
any of the following:

           (a) the release or waiver, by operation of law or otherwise, of the
         performance or observance by the Issuer of any express or implied
         agreement, covenant, term or condition relating to the Preferred
         Securities to be performed or observed by the Issuer;

           (b) the extension of time for the payment by the Issuer of all or any
         portion of the Distributions (other than an extension of time for
         payment of Distributions that result from any Extended Interest Payment
         Period), Redemption Price, Liquidation Distribution (as defined in the
         Declaration) or any other sums payable under the terms of the Preferred
         Securities or the extension of time for the performance of any other
         obligation under, arising out of, or in connection with, the Preferred
         Securities (other than an extension of time for payment of
         Distributions that result from any Extended Interest Payment Period);

           (c) any failure, omission, delay or lack of diligence on the part of
         the Holders to enforce, assert or exercise any right, privilege, power
         or remedy conferred on the Holders pursuant to the terms of the
         Preferred Securities, or any action on the part of the Issuer granting
         indulgence or extension of any kind;

           (d) the voluntary or involuntary liquidation, dissolution, sale of
         any collateral, receivership, insolvency, bankruptcy, assignment for
         the benefit of creditors, reorganization, arrangement, composition or
         readjustment of debt of, or other similar proceedings affecting, the
         Issuer or any of the assets of the Issuer;

           (e)  any invalidity of, or defect or deficiency in, the Preferred
         Securities;

           (f) the settlement or compromise of any obligation guaranteed hereby
         or hereby incurred; or

           (g) any other circumstance whatsoever that might otherwise constitute
         a legal or equitable discharge or defense of a guarantor, it being the
         intent of this Section 5.03 that the obligations of the Guarantor with
         respect to the Guarantee Payments shall be absolute and unconditional
         under any and all circumstances.

                                      11
<PAGE>


         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

         SECTION 5.04. ENFORCEMENT OF GUARANTEE. The Guarantor and the Guarantee
Trustee expressly acknowledge that (i) this Guarantee Agreement will be
deposited with the Guarantee Trustee to be held for the benefit of the
Holders;(ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) Holders representing not less than a
Majority in liquidation amount of the Preferred Securities have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Guarantee Trustee in respect of this Guarantee Agreement or
exercising any trust or other power conferred upon the Guarantee Trustee under
this Guarantee Agreement; and (iv) if the Guarantee Trustee fails to enforce
this Guarantee Agreement as provided in clauses (ii) and (iii) above, any Holder
may institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement, without first instituting a legal
proceeding against the Issuer, the Guarantee Trustee or any other Person.
Notwithstanding the foregoing, if the Guarantor has failed to make a Guarantee
Payment, a Holder may directly institute a proceeding against the Guarantor for
enforcement of this Guarantee Agreement for such payment without first
instituting a legal proceeding against the Issuer, the Guarantee Trustee or any
other Person.

         SECTION 5.05.  GUARANTEE OF PAYMENT.  This Guarantee Agreement
creates a guarantee of payment and not merely of collection.  This Guarantee
Agreement will not be discharged except by payment of the Guarantee Payments
in full (without duplication of amounts theretofore paid by the Issuer) or
upon the distribution of the Debentures to the Holders as provided in the
Declaration.

         SECTION 5.06. SUBROGATION. The Guarantor shall be subrogated to all (if
any) rights of the Holders against the Issuer in respect of any amounts paid to
the Holders by the Guarantor under this Guarantee Agreement; PROVIDED, HOWEVER,
that the Guarantor shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any rights which it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Guarantee Agreement,
if, at the time of any such payment, any amounts are due and unpaid under this
Guarantee Agreement. If any amount shall be paid to the Guarantor in violation
of the preceding sentence, the Guarantor agrees to hold such amount in trust for
the Holders and to pay over such amount to the Holders.

         SECTION 5.07. INDEPENDENT OBLIGATIONS. The Guarantor acknowledges that
its obligations hereunder are independent of the obligations of the Issuer with
respect to the Preferred Securities and that the Guarantor shall be liable as
principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03 hereof.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

PASSU with or junior in interest to the Debentures, if at such time (i)the
Guarantor shall be in default with respect to its Guarantee Payments or other
payment obligations hereunder,(ii) there shall have occurred any event of
default under the Declaration or (iii) the Guarantor shall have given notice of

or permit the Common Securities to be transferred except to the extent such
transfer is permitted under Section 9.01 of the Declaration; PROVIDED that any
permitted successor of the Guarantor under the Indenture may succeed to the
Guarantor's ownership of the Common Securities and (ii) will use reasonable
efforts to cause the Issuer to continue to be treated as a grantor trust for
United States federal income tax purposes except in connection with a
distribution of Debentures as provided in the Declaration.

         SECTION 6.02. SUBORDINATION. This Guarantee Agreement will
constitute an unsecured obligation of the Guarantor and will rank
(i) subordinate and junior in right of payment to all other liabilities of the
Guarantor, including the Debentures, except those made PARI PASSU or
subordinate by their terms, and (ii) senior to all capital stock (other than
the most senior preferred stock issued, from time to time, if any, by the
Guarantor, which preferred stock will rank PARI PASSU with this Guarantee
Agreement) now or hereafter issued by the Guarantor and to any guarantee now
or hereafter entered into by the Guarantor in respect of any of its capital
stock (other than the most senior preferred stock issued, from time to time,
if any, by the Guarantor). The Guarantor's obligations under this Guarantee
Agreement will rank PARI PASSU with respect to obligations under

                                      13
<PAGE>

other guarantee agreements which it may enter into from time to time to the
extent that (i) such agreements shall be entered into in substantially the
form hereof and provide for comparable guarantees by the Guarantor of payment
on preferred securities issued by other trusts, partnerships or other
entities affiliated with the Guarantor that are financing vehicles of the
Guarantor and (ii) the debentures or other evidences of indebtedness of the
Guarantor relating to such preferred securities are junior subordinated,
unsecured indebtedness of the Guarantor.

be of no further force and effect (i) upon full payment of the Redemption Price
of all Preferred Securities, (ii) upon the distribution of Debentures to Holders
and holders of Common Securities in exchange for all of the Preferred Securities
and Common Securities, (iii) upon full payment of the amounts payable in
accordance with the Declaration upon liquidation of the Issuer or (iv) upon the
distribution, if any, of Common Stock to Holders in respect of the conversion of
all such Holders' Preferred Securities into Common Stock. Notwithstanding the
foregoing, this Guarantee Agreement will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder must restore payment
of any sums paid with respect to the Preferred Securities or under this
Guarantee Agreement.

applicable law, the Guarantor shall indemnify and hold harmless each Indemnified
Person from and against any loss, damage or claim incurred by such Indemnified
Person by reason of any act or omission performed or omitted by such Indemnified

Pogo Producing Company
5 Greenway Plaza, Suite 2700
Houston, Texas 77046

Ladies and Gentlemen:

          We have acted as counsel to Pogo Producing Company, a Delaware
corporation ("Pogo Producing"), and Pogo Trust I and Pogo Trust II, each of
which is a Delaware statutory business trust (collectively, the "Trusts"),
relating to the registration of (i) $250,000,000 aggregate principal amount of
Junior Subordinated Debt Securities of Pogo Producing and (ii) $250,000,000
aggregate liquidation amount of preferred securities of the Trusts.  In that
connection, reference is made to the registration statement under the Securities
Act of 1933, as amended, of Pogo Producing and the Trusts on Form S-3
(Registration Nos. 333-75105, 333-75105-01, and 333-75105-02) filed with the
Securities and Exchange Commission (the "Commission") on March 26, 1999, as
amended by Pre-Effective Amendment No. 1 thereto filed with the Commission on
May 3, 1999 and Pre-Effective Amendment No. 2 thereto filed with the Commission
on May 10, 1999 and declared effective by the Commission on May 13, 1999 (as
amended, the "Registration Statement"), including a prospectus dated May 13,
1999 (the "Prospectus"), and a prospectus supplement dated May 26, 1999 (the
"Prospectus Supplement") describing the 6 1/2% Cumulative Quarterly Income
Convertible Preferred Securities, Series A of Pogo Trust I (the "Preferred
Securities") and the 6 1/2% Junior Subordinated Debentures, Series A due 2029 of
Pogo Producing (the "Junior Subordinated Debentures").  Capitalized terms not
otherwise defined herein shall have the meaning specified in the Prospectus and
the Prospectus Supplement.

          We have examined the Prospectus, the Prospectus Supplement, and such
other documents and corporate records as we have deemed necessary or appropriate
for purposes of this opinion.  In addition, we have assumed that the Junior
Subordinated Debentures and the Preferred Securities will be issued in
accordance with the operative documents described in the Prospectus and the
Prospectus Supplement.

          Based on the assumptions contained therein, the statements of legal
conclusion set forth under the heading "Federal Income Tax Consequences" in the
Prospectus Supplement reflect our opinions on the material United States federal
income tax consequences of the ownership and disposition of the Preferred
Securities.

Pogo Producing company                   -2-                         May 27,1999

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to this Firm in the section
captioned "Federal Income Tax Consequences" in the Prospectus Supplement.  In
giving this consent, we do not thereby admit that we come within the category of
a person whose consent is required under Section 7 of the Securities Act of
1933, as amended, or the rules and regulations of the Commission thereunder.

                                        Very truly yours,

                                        BAKER & BOTTS, L.L.P.
