     There are no separate financial statements of the Apache Trusts in this
prospectus. We do not believe these financial statements would be helpful
because:

     - the Apache Trusts are wholly-owned subsidiaries of Apache, which files
       consolidated financial information under the Securities Exchange Act;

     - the Apache Trusts will not have any independent operations other than
       issuing trust preferred securities and trust common securities,
       purchasing debt securities of Apache Corporation and other necessary or
       incidental activities as described in this prospectus; and

     - Apache guarantees the trust preferred securities of the Apache Trusts.


     Our web site address is http://www.apachecorp.com. The information on our
web site is not incorporated by reference into this prospectus. You should rely
only on the information incorporated by reference or provided in this prospectus
or any prospectus supplement. Neither Apache nor either Apache Trust has
authorized anyone to provide you with different information.



     Neither Apache nor either Apache Trust is making an offer of the securities
covered by this prospectus in any state where the offer is not permitted. You
should not assume that the information in this prospectus or any prospectus
supplement or in any other document incorporated by reference in this prospectus
is accurate as of any date other than the date of those documents.

           CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference in this
prospectus contain "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. These statements are based on our current expectations, estimates and
projections. Therefore, they could ultimately prove to be inaccurate. Our plans
for capital and exploratory spending and for cost and expense reduction may
change if business conditions, such as energy prices and world economic
conditions, change. Other factors that may have a direct bearing on our results
of operations and financial condition are:

     - competitive practices in the industries in which we compete;

     - fluctuations in oil and gas prices that have not been properly hedged or
       that are inconsistent with our marketing activities;

     - operational and systems risks;

     - environmental liabilities that are not covered by indemnity or insurance;

     - general economic and capital market conditions, including fluctuations in
       interest rates; and

     - the impact of current and future laws and governmental regulations
       (particularly environmental regulations) affecting the energy industry in
       general and Apache's operations in particular.

                               APACHE CORPORATION

     Apache Corporation is a Delaware corporation formed in 1954. We are an
independent energy company that explores for, develops and produces natural gas,
crude oil and natural gas liquids. In North America, our exploration and
production interests are focused on the Gulf of Mexico, the Anadarko Basin, the
Permian Basin, the Gulf Coast and the Western Sedimentary Basin of Canada.
Outside of North America, we have exploration and production interests offshore
Western Australia and in Egypt and exploration interests in Poland and offshore
The People's Republic of China.

     We hold interests in many of our U.S., Canadian and international
properties through operating subsidiaries, such as Apache Canada Ltd., DEK
Energy Company, which was formerly known as DEKALB Energy Company, Apache Energy
Limited, which was formerly known as Hadson Energy Limited, Apache
International, Inc., and Apache Overseas, Inc. The properties referred to in
this prospectus, in any prospectus supplement or in any other document
incorporated by reference in this prospectus may be held by our subsidiaries. We
treat all operations as one line of business.

                                 APACHE TRUSTS

     We created Apache Trust I and Apache Trust II, each of which is a Delaware
business trust, pursuant to trust agreements and the filing of certificates of
trust with the Delaware Secretary of State. We will execute amended and restated
trust agreements for the Apache Trusts, referred to in this prospectus as the
"trust agreements," which will state the terms and conditions for the Apache
Trusts to issue and sell their trust preferred securities and trust common
securities. We have filed a form of trust agreement as an exhibit to the
registration statement of which this prospectus forms a part.

                                        3
<PAGE>   7

     The Apache Trusts will exist solely to:

     - issue and sell their trust preferred securities and trust common
       securities;

     - use the proceeds from the sale of their trust preferred securities and
       trust common securities to purchase Apache's debt securities; and

     - engage in other activities that are necessary or incidental to the above
       purposes.


     We will hold directly or indirectly all of the trust common securities of
each of the Apache Trusts. The trust common securities will represent an
aggregate liquidation amount equal to at least 3% of each Apache Trust's total
capitalization. The trust preferred securities will represent the remaining
percentage of each Apache Trust's total capitalization. The trust common
securities will have terms substantially identical to, and will rank equal in
priority of payment with, the trust preferred securities. However, if Apache
defaults on the debt securities owned by an Apache Trust or another event of
default under the trust agreement occurs, then, so long as the default
continues, cash distributions and liquidation, redemption and other amounts
payable or deliverable on the securities of that trust must be paid or delivered
to the holders of the trust preferred securities of that trust before the
holders of the common securities of that trust.



     The Apache Trusts may not borrow money, issue debt, execute mortgages or
pledge any of their assets.


     The trust preferred securities will be guaranteed by us as described in
this prospectus and the applicable prospectus supplement.

     Unless otherwise specified in the applicable prospectus supplement, the
following four trustees will conduct each Apache Trust's business and affairs:

     - The Chase Manhattan Bank, a New York banking corporation, as property
       trustee;

     - Chase Manhattan Bank Delaware, a Delaware banking corporation, as
       Delaware trustee; and

     - two of our officers, as administrative trustees.


     Only we, as direct or indirect owner of the trust common securities, can
remove or replace the administrative trustees. In addition, we can increase or
decrease the number of administrative trustees. Also, we, as direct or indirect
holder of the trust common securities, will generally have the sole right to
remove or replace the property and Delaware trustees. However, if Apache
defaults on the debt securities owned by an Apache Trust or another event of
default under the trust agreement occurs, then, so long as that default is
continuing, the holders of a majority in liquidation amount of the outstanding
trust preferred securities of that trust may remove and replace the property and
Delaware trustees for that trust.


     We will pay all fees and expenses related to the Apache Trusts and the
offering of the trust preferred securities. We will also pay all ongoing costs
and expenses of the Apache Trusts, except each trust's obligations under the
trust preferred securities and trust common securities.

</TABLE>

     Our ratios of earnings to fixed charges and our ratios of earnings to
combined fixed charges and preferred stock dividends were computed based on:


     - "earnings," which consist of consolidated income or losses from
       continuing operations plus income taxes and fixed charges, except
       capitalized interest or, in the case of our ratios of earnings to
       combined fixed charges and preferred stock dividends, those earnings plus
       preferred stock dividends; and


     - "fixed charges," which consist of consolidated interest on indebtedness,
       including capitalized interest, amortization of debt discount and
       expense, and the estimated portion of rental expense attributable to
       interest.

     Due to the $243.2 million non-cash write-down of the carrying value of our
U.S. proved oil and gas properties for the year ended December 31, 1998, our
1998 earnings were inadequate to cover fixed charges by $236.8 million and
inadequate to cover combined fixed charges and preferred stock dividends by
$239.7 million.

     On May 17, 1995, Apache acquired DEKALB Energy Company, which is now known
as DEK Energy Company, through a merger which resulted in DEKALB becoming a
wholly-owned subsidiary of Apache. The merger was accounted for as a "pooling of
interests." As a result, our financial information for all preceding periods was
restated.

                                USE OF PROCEEDS

     Unless otherwise indicated in an accompanying prospectus supplement, we
expect to use the net proceeds from the sale of our securities for general
corporate purposes, which may include, among other things:

     - the repayment of outstanding indebtedness;

     - working capital;

     - capital expenditures; and

     - acquisitions.

     The precise amount and timing of the application of such proceeds will
depend upon our funding requirements and the availability and cost of other
funds.

     The Apache Trusts will use all proceeds from the sale of the trust common
and trust preferred securities to purchase debt securities of Apache.

                          DESCRIPTION OF CAPITAL STOCK


     The following descriptions of our common stock and preferred stock,
together with the additional information included in any applicable prospectus
supplements, summarize the material terms and provisions of these types of
securities. For the complete terms of our common stock and preferred stock,
please refer to our charter, bylaws and stockholder rights plan that are
incorporated by reference into the registration statement that includes this
prospectus or may be incorporated by reference in this prospectus. The terms of
these securities may also be affected by the General Corporation Law of the
State of Delaware.


     Under our charter, our authorized capital stock consists of 215,000,000
shares of common stock, $1.25 par value per share, and 5,000,000 shares of
preferred stock, no par value. We will describe the specific terms of any common
stock or preferred stock we may offer in a prospectus supplement. If indicated
in a prospectus supplement, the terms of any common stock or preferred stock
offered under that prospectus supplement may differ from the terms described
below.

COMMON STOCK

     As of February 29, 2000, Apache had approximately 113,640,647 shares of
common stock issued and outstanding. Also as of February 29, 2000, subject to
stock dividends and other events, up to 5,737,900 shares of common stock were
issuable upon conversion of our Series C preferred stock, as described below
under "Preferred Stock -- Series C." Each outstanding share of common stock
currently has attached to it one preferred share purchase right issued under our
stockholder rights plan, which is summarized below. All outstanding shares of
common stock are, and any shares of common stock sold pursuant to this
prospectus will be, duly authorized, validly issued, fully paid and
nonassessable.

  Voting

     For all matters submitted to a vote of stockholders, each holder of common
stock is entitled to one vote for each share registered in his or her name on
the books of Apache. Our common stock does not have cumulative voting rights. As
a result, subject to the voting rights of Series B and Series C preferred
stockholders and any future holders of our preferred stock, persons who hold
more than 50% of the outstanding common stock entitled to elect members of the
board of directors can elect all of the directors who are up for election in a
particular year.

  Dividends

     If our board of directors declares a dividend, holders of common stock will
receive payments from the funds of Apache that are legally available to pay
dividends. However, this dividend right is subject to any preferential dividend
rights we have granted to Series B and Series C preferred stockholders or may
grant to future holders of preferred stock.

  Liquidation

     If Apache is dissolved, the holders of common stock will be entitled to
share ratably in all the assets that remain after we pay our liabilities and any
amounts we may owe to the persons who hold our preferred stock.

  Other Rights and Restrictions

     Holders of common stock do not have preemptive rights, and they have no
right to convert their common stock into any other securities. Our common stock
is not subject to redemption by Apache. Our charter and bylaws do not restrict
the ability of a holder of common stock to transfer his or her shares of common
stock.

                                        7
<PAGE>   11

     Delaware law provides that, if we make a distribution to our stockholders
other than a distribution of our capital stock either when we are insolvent or
when we would be rendered insolvent, then our stockholders would be required to
pay back to us the amount of the distribution we made to them, or the portion of
the distribution that causes us to become insolvent, as the case may be.

  Listing

     Our common stock is listed on the New York Stock Exchange and the Chicago
Stock Exchange under the symbol "APA."

  Transfer Agent and Registrar

     The transfer agent and registrar for our common stock is Norwest Bank
Minnesota, National Association.

PREFERRED STOCK

  General

     We have 5,000,000 shares of no par preferred stock authorized, of which
25,000 shares have been designated as Series A Junior Participating Preferred
Stock, 100,000 shares have been designated as 5.68% Series B Cumulative
Preferred Stock and 140,000 shares have been designated as Automatically
Convertible Equity Securities, Conversion Preferred Stock, Series C. The
remaining shares of preferred stock are undesignated.

     Our charter authorizes our board of directors to issue preferred stock in
one or more series and to determine the voting rights and dividend rights,
dividend rates, liquidation preferences, conversion rights, redemption rights,
including sinking fund provisions and redemption prices, and other terms and
rights of each series of preferred stock.

  Series A

     The shares of Series A preferred stock are authorized for issuance pursuant
to rights that trade with outstanding Apache common stock and are reserved for
issuance upon the exercise of the rights discussed below under the caption
"-- Stockholder Rights Plan."

  Series B

     As of February 29, 2000, Apache had issued and outstanding 100,000 shares
of Series B preferred stock in the form of one million depositary shares, each
representing one-tenth ( 1/10) of a share of Series B preferred stock. The
Series B preferred stock has no stated maturity, is not subject to a sinking
fund and is not convertible into Apache common stock or any other securities.
Apache has the option to redeem the Series B preferred stock at $1,000 per share
on or after August 25, 2008. Holders of the depositary shares are entitled to
receive cumulative cash dividends at an annual rate of $5.68 per depositary
share (based on $56.80 for each share of Series B preferred stock) when, as and
if declared by Apache's board of directors.

     The Series B preferred stock has a liquidation preference of $1,000 per
share, which is equivalent to $100 per depositary share, plus accrued and unpaid
dividends.

     The Series B preferred stock ranks prior and superior to our common stock
and Series A preferred stock as to payment of dividends and distribution of
assets upon our dissolution, liquidation or winding up.

     The Series B preferred stock ranks equal to the Series C preferred stock as
to payment of dividends and distribution of assets upon dissolution, liquidation
or winding up.

                                        8
<PAGE>   12

     If dividends are not paid on the Series B preferred stock, cash payments on
our common stock and any other capital stock of Apache that ranks junior to the
Series B preferred stock as to dividends are prohibited and payments on any
other capital stock of Apache that ranks equal to the Series B preferred stock
as to dividends, including the Series C preferred stock, are restricted.


     Shares of Series B preferred stock generally do not have voting rights.
However, if we fail to pay the equivalent of six quarterly dividends payable on
the Series B preferred stock or another class or series of preferred stock that
ranks equally with the Series B preferred stock, including the Series C
preferred stock, then we will increase the size of our board of directors by two
members. The holders of the Series B preferred stock and any other class or
series of preferred stock ranking equally with the Series B preferred stock,
including the Series C preferred stock, voting as a single class together with
any other class of preferred stock ranking equally, will then have the right to
vote for the two additional directors. This voting right would continue until we
have paid all past dividends on all preferred stock.


     Without the vote of at least 80% of the outstanding shares of Series B
preferred stock, we may not amend any provision in our charter so as to
adversely affect the powers, preferences, privileges or rights of the Series B
preferred stock.

     Without the approval of the holders, voting together as a single class, of
80% of all the shares of Series B preferred stock then outstanding and all
shares of any other series of the preferred stock of Apache ranking equally as
to dividends or upon liquidation, including the Series C preferred stock, we
will not:

     - issue, authorize or increase the authorized amount of, or issue or
       authorize any obligation or security convertible into or evidencing a
       right to purchase, any stock of any class ranking prior to the Series B
       preferred stock as to dividends or upon liquidation; or

     - reclassify any authorized Apache stock into any stock of any class, or
       any obligation or security convertible into or evidencing a right to
       purchase such stock, ranking prior to the Series B preferred stock,

provided that no such vote will be required for Apache to take any of these
actions to issue, authorize or increase the authorized amount of, or issue or
authorize any obligation or security convertible into or evidencing a right to
purchase, any stock ranking equally with or junior to the Series B preferred
stock.

     Without the approval of the holders of at least a majority of the shares of
Series B preferred stock then outstanding, we will not become a party to any
merger, conversion, consolidation or compulsory share exchange unless the terms
of that transaction do not provide for a change in the terms of the Series B
preferred stock and the Series B preferred stock ranks equally with or prior to
any capital stock of the surviving corporation as to dividends or upon
liquidation, dissolution or winding up other than prior-ranking Apache stock
previously authorized with the consent of holders of the Series B preferred
stock.

  Series C

     As of February 29, 2000, Apache had issued and outstanding 138,482 shares
of Series C preferred stock in the form of 6,924,100 depositary shares, each
representing one-fiftieth ( 1/50) of a share of Series C preferred stock.
Holders of the shares are entitled to receive cumulative cash dividends at an
annual rate of $2.015 per depositary share (based on $100.75 for each share of
Series C preferred stock) when, as and if declared by Apache's board of
directors.

     On May 15, 2002, each depositary share will automatically convert into
shares of Apache common stock at an exchange rate that will be not more than one
share and not less than

                                        9
<PAGE>   13

0.8197 shares of Apache common stock per depositary share. The exchange rate
will depend on the current market value of Apache common stock prior to the date
of conversion, and is subject to adjustments for stock dividends and other
events.

     At any time prior to May 15, 2002, holders may elect to convert each
depositary share into 0.8197 of a share of Apache common stock, subject to
adjustments for stock dividends and other events.

     The Series C preferred stock has a liquidation preference of $1,550 per
share, which is equivalent to $31 per depositary share, plus accrued and unpaid
dividends.

     The Series C preferred stock ranks prior and superior to our common stock
and Series A preferred stock as to payment of dividends and distribution of
assets upon our dissolution, liquidation or winding up.

     The Series C preferred stock ranks equal to the Series B preferred stock as
to payment of dividends and distribution of assets upon our dissolution,
liquidation or winding up.

     If dividends are not paid on the Series C preferred stock, cash payments on
our common stock and any other capital stock of Apache that ranks junior to the
Series C preferred stock as to dividends are prohibited and payments on any
other capital stock of Apache that ranks equal to the Series C preferred stock
as to dividends, including the Series B preferred stock, are restricted.


     Shares of Series C preferred stock generally do not have voting rights.
However, if we fail to pay the equivalent of six quarterly dividends payable on
the Series C preferred stock or another class or series of preferred stock that
ranks equally with the Series C preferred stock, including the Series B
preferred stock, then we will increase the size of our board of directors by two
members. The holders of the Series C preferred stock and any other class or
series of preferred stock ranking equally with the Series C preferred stock,
including the Series B preferred stock, voting as a single class together with
any other class of preferred stock ranking equally, will then have the right to
vote for the two additional directors. This voting right would continue until we
have paid all past dividends on all preferred stock.


     Without the vote of at least 80% of the outstanding shares of Series C
preferred stock, we may not amend any provision in our charter so as to
adversely affect the powers, preferences, privileges or rights of the Series C
preferred stock.

     Without the approval of the holders, voting together as a single class, of
80% of all the shares of Series C preferred stock then outstanding and all
shares of any other series of the preferred stock of Apache ranking equally as
to dividends or upon liquidation, including the Series B preferred stock, we
will not:

     - issue, authorize or increase the authorized amount of, or issue or
       authorize any obligation or security convertible into or evidencing a
       right to purchase, any stock of any class ranking prior to the Series C
       preferred stock as to dividends or upon liquidation; or

     - reclassify any authorized Apache stock into any stock of any class, or
       any obligation or security convertible into or evidencing a right to
       purchase such stock, ranking prior to the Series C preferred stock,

provided that no such vote will be required for Apache to take any of these
actions to issue, authorize or increase the authorized amount of, or issue or
authorize any obligation or security convertible into or evidencing a right to
purchase, any stock ranking equally with or junior to the Series C preferred
stock.

     Without the approval of the holders of at least a majority of the shares of
Series C preferred stock then outstanding, we will not become a party to any
merger, conversion, consolidation or compulsory share exchange unless the terms
of that transaction do not provide for a change in
                                       10
<PAGE>   14

the terms of the Series C preferred stock and the Series C preferred stock ranks
equally with or prior to any capital stock of the surviving corporation as to
dividends or upon liquidation, dissolution or winding up, other than
prior-ranking Apache stock previously authorized with the consent of holders of
the Series C preferred stock.

     The depositary shares representing Series C preferred stock are listed on
the New York Stock Exchange under the symbol "APAPrC."

     UNDESIGNATED PREFERRED STOCK


     This summary of the undesignated preferred stock discusses terms and
conditions may apply to preferred stock offered under this prospectus. The
applicable prospectus supplement will describe the particular terms of each

supplement, the terms of any series may differ from the terms described below.


     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of any preferred
stock being offered by this prospectus. It does not restate the terms and
provisions in their entirety. We urge you to read our charter and any applicable
certificate of designation that may be on file because they, and not this

our charter as an exhibit to the registration statement which includes this
prospectus. We will incorporate by reference as an exhibit to the registration
statement the form of any certificate of designation before the issuance of any
series of preferred stock.


     The prospectus supplement for any preferred stock that we actually offer
pursuant to this prospectus may include some or all of the following terms:


     - the designation of the series of preferred stock;

     - the number of shares of preferred stock offered, the liquidation

                                       11
<PAGE>   15

     Subject to our charter and to any limitations imposed by any
then-outstanding preferred stock, we may issue additional series of preferred
stock, at any time or from time to time, with such powers, preferences, rights
and qualifications, limitations or restrictions as the board of directors
determines, and without further action of the stockholders, including holders of
our then outstanding preferred stock, if any.

STOCKHOLDER RIGHTS PLAN

     In 1995, our board of directors adopted a stockholder rights plan to
replace the former plan adopted in 1986. Under our stockholder rights plan, each
of our common stockholders received a dividend of one "preferred stock purchase
right" for each outstanding share of common stock that the stockholder owned. We
refer to these preferred stock purchase rights as the "rights." Unless the
rights have been previously redeemed, all shares of Apache common stock are
issued with rights. The rights trade automatically with our shares of common
stock and become exercisable only under certain circumstances described below.

     The purpose of the rights is to encourage potential acquirors to negotiate
with our board of directors before attempting a takeover bid and to provide our
board of directors with leverage in negotiating on behalf of our stockholders
the terms of any proposed takeover. The rights may have certain anti-takeover
effects. They should not, however, interfere with any merger or other business
combination approved by our board of directors.

     The following description is a summary of all the material terms of our
stockholder rights plan. It does not restate these terms in their entirety. We
urge you to read our stockholder rights plan because it, and not this
description, defines the terms and provisions of our plan. Our stockholder
rights plan is incorporated by reference as an exhibit to the registration
statement that includes this prospectus. You may obtain a copy at no charge by
writing to us at the address listed under the caption "Where You Can Find More
Information."

  Exercise of Rights

     Until a right is exercised, the holder of a right will not have any rights
as a stockholder. When the rights become exercisable, holders of the rights will
be able to purchase from us 1/10,000th of a share of our Series A preferred
stock, at a purchase price of $100, subject to adjustment, per 1/10,000th of a
share.

     In general, the rights will become exercisable upon the earlier of:

     - ten calendar days after a public announcement that a person or group has
       acquired beneficial ownership of 20% or more of the outstanding shares of
       our common stock; or

     - ten business days after the beginning of a tender offer or exchange offer
       that would result in a person or group beneficially owning 30% or more of
       our common stock.

  Flip in Event

     If a person or group becomes the beneficial owner of 20% or more of our
common stock, then each right will then entitle its holder to receive, upon
exercise, a number of shares of our common stock which is equal to the exercise
price of the right divided by one-half of the market price of our common stock
on the date of the occurrence of this event. We refer to this occurrence as a
"flip in event." A flip in event does not occur if there is an offer for all of
our outstanding shares of common stock that our board of directors determines is
fair to our stockholders and in Apache's best interests.

                                       12
<PAGE>   16

  Flip Over Event

     If, at any time after a person or group becomes the beneficial owner of 20%
or more of our common stock, Apache is acquired in a merger or other transaction
in which Apache does not survive or in which our common stock is changed or
exchanged or 50% or more of Apache's assets or earning power is sold or
transferred, then each holder of a right will be entitled to receive, upon
exercise, a number of shares of common stock of the acquiring company in the
transaction equal to the exercise price of the right divided by one-half of the
market price of the acquiring company's common stock on the date of the
occurrence of this event. This exercise right will not occur if the merger or
other transaction follows an offer for all of our outstanding shares of common
stock that our board of directors determines is fair to our stockholders and in
Apache's best interests.

  Exchange of Rights

     At any time after a flip in event, our board of directors may exchange the
rights by providing to the holder one share of our common stock or 1/10,000th of
a share of our Series A preferred stock for each of the holder's rights.

  Redemption of Rights

     At any time before a flip in event, we may redeem the rights at a price of
$.01 per right. The rights will expire on the close of business on January 31,
2006, subject to earlier expiration or termination as described in our
stockholder rights plan.

     Unless and until the rights become exercisable, they will be transferred
with and only with the shares of Apache common stock.

ANTI-TAKEOVER EFFECT OF PROVISIONS OF APACHE'S CHARTER AND BYLAWS AND DELAWARE
LAW

     Apache's charter and bylaws include provisions designed to prevent the use
of certain tactics in connection with a potential takeover of Apache. Please
refer to our charter and bylaws that are incorporated by reference into the
registration statement that includes this prospectus. You may obtain copies at
no charge by writing to us at the address listed under the caption "Where You
Can Find More Information."

     Certain provisions of Delaware law described below also have an
anti-takeover effect.

  Apache's Bylaws

     Apache's board of directors is divided into three classes, with directors
serving staggered three-year terms.

  Apache's Charter

     Article Nine provides that Apache's board of directors is divided into
three classes, with directors serving staggered three-year terms.

     Article Twelve generally stipulates that the affirmative vote of 80% of our
voting shares is required to adopt any agreement for the merger or consolidation
with or into any other corporation which is the beneficial owner of more than 5%
of our voting shares. Article Twelve further provides that such 80% approval is
necessary to authorize any sale or lease of assets between Apache and any
beneficial holder of 5% or more of our voting shares.

                                       13
<PAGE>   17

     Article Fourteen contains a "fair price" provision which requires that any
tender offer made by a beneficial owner of more than 5% of our outstanding
voting stock in connection with any:

     - plan of merger, consolidation or reorganization;

     - sale or lease of substantially all of our assets; or

     - issuance of our equity securities to the 5% stockholder

must provide at least as favorable terms to each holder of common stock other
than the stockholder making the tender offer.


     Article Fifteen contains an "anti-greenmail" mechanism which prohibits
Apache from acquiring any voting stock from the beneficial owner of more than 5%
of Apache's outstanding voting stock, except for acquisitions pursuant to a
tender offer to all holders of voting stock on the same price, terms and
conditions, acquisitions in compliance with Rule 10b-18 of the Securities
Exchange Act of 1934 and acquisitions at a price not exceeding the market value
per share.


     Article Sixteen prohibits the stockholders from acting by written consent
in lieu of a meeting.

     The affirmative vote of 80% of the voting shares is required to amend or
adopt any provision inconsistent with Articles Nine, Twelve, Fourteen and
Sixteen.

  Business Combinations with Interested Stockholders Under Delaware Law

     Section 203 of the Delaware General Corporation Law prevents a publicly
held corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless:

     - before the date on which the person became an interested stockholder, the
       board of directors of the corporation approved either the business
       combination or the transaction in which the person became an interested
       stockholder;

     - the interested stockholder owned at least 85% of the outstanding voting
       stock of the corporation at the beginning of the transaction in which it
       became an interested stockholder, excluding stock held by directors who
       are also officers of the corporation and by employee stock plans that do
       not provide participants with the rights to determine confidentially
       whether shares held subject to the plan will be tendered in a tender or
       exchange offer; or

     - on or after the date on which the interested stockholder became an
       interested stockholder, the business combination is approved by the board
       of directors and the holders of two-thirds of the outstanding voting
       stock of the corporation voting at a meeting, excluding the voting stock
       owned by the interested stockholder.

     As defined in Section 203, an "interested stockholder" is generally a
person owning 15% or more of the outstanding voting stock of the corporation. As
defined in Section 203, a "business combination" includes mergers,
consolidations, stock and assets sales and other transactions with the
interested stockholder.

     The provisions of Section 203 may have the effect of delaying, deferring or
preventing a change of control of Apache.

                        DESCRIPTION OF DEPOSITARY SHARES


     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the depositary
shares that we may offer under this prospectus and the related deposit
agreements and depositary receipts. Specific deposit agreements and depositary
receipts will contain additional important terms and provisions. The forms of
the applicable deposit agreement and depositary receipt will be incorporated by
reference as an exhibit to the registration statement that includes this
prospectus before we issue any depositary shares.


     This summary of depositary agreements, depositary shares and depositary
receipts relates to terms and conditions applicable to these types of securities
generally. The particular terms of any series of depositary shares will be
summarized in the applicable prospectus supplement. If indicated in the
applicable prospectus supplement, the terms of any series may differ from the
terms summarized below.

GENERAL

     We may elect to offer fractional shares of preferred stock rather than full
shares of preferred stock. If so, we will issue "depositary receipts" for these
"depositary shares." Each depositary share will represent a fraction of a share
of a particular series of preferred stock. Each holder of a depositary share
will be entitled, in proportion to the fraction of preferred stock represented
by that depositary share, to all the rights, preferences and privileges of the
preferred stock, including dividend, voting, redemption, conversion and
liquidation rights, if any, and all the limitations of the preferred stock. We
will enter into a deposit agreement with a depositary, which will be named in
the applicable prospectus supplement.

     In order to issue depositary shares, we will issue preferred stock and
immediately deposit these shares with the depositary. The depositary will then
issue and deliver depositary receipts to the persons who purchase depositary
shares. Each whole depositary share issued by the depositary may represent a
fraction of a share of preferred stock held by the depositary. The depositary
will issue depositary receipts in a form that reflects whole depositary shares,
and each depositary receipt may evidence any number of whole depositary shares.

     Pending the preparation of definitive engraved depositary receipts, if any,
a depositary may, upon our written order, issue temporary depositary receipts,
which will temporarily entitle the holders to all the rights pertaining to the
definitive depositary receipts. We will bear the costs and expenses of promptly
preparing definitive depositary receipts and of exchanging the temporary
depositary receipts for such definitive depositary receipts.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all cash and non-cash distributions it
receives with respect to the underlying preferred stock to the record holders of
depositary shares in proportion to the number of depositary shares they hold,
subject to any obligations of the record holders to file proofs, certificates
and other information and to pay any taxes or other governmental charges. In the
case of any non-cash distribution, Apache may determine that the distribution
cannot be made proportionately or the depositary may determine that it may not
be feasible to make the distribution. If so, the depositary may, with our
approval, adopt a method it deems equitable and practicable to effect the
distribution, including the sale, public or private, of the securities or other
non-cash property it receives in the distribution at a place and on terms it
deems proper. The amounts distributed by the depositary will be reduced by any
amount required to be withheld by Apache or the depositary on account of taxes.

                                       15
<PAGE>   19

REDEMPTION OF DEPOSITARY SHARES

     If the shares of preferred stock that underlie the depositary shares are
redeemable and we redeem the preferred stock, the depositary will redeem the
depositary shares from the proceeds it receives from the redemption of the
preferred stock it holds. The depositary will redeem the number of depositary
shares that represent the amount of underlying preferred stock that we have
redeemed. The redemption price for depositary shares will be in proportion to
the redemption price per share that we paid for the underlying preferred stock.
If we redeem less than all of the depositary shares, the depositary will select
which depositary shares to redeem by lot, or some substantially equivalent
method.

     After a redemption date is fixed, the depositary shares to be redeemed no
longer will be considered outstanding. The rights of the holders of the
depositary shares will cease, except for the rights to receive money or other
property upon redemption. In order to redeem their depositary shares, holders
must surrender their depositary receipts to the depositary.

VOTING THE PREFERRED STOCK

     When the depositary receives notice about any meeting at which the holders
of preferred stock are entitled to vote, the depositary will mail the
information contained in the notice to the record holders of depositary shares
related to that preferred stock. Each record holder of depositary shares on the
record date, which will be the same date as the record date for the preferred
stock, will be entitled to instruct the depositary on how to vote the shares of
preferred stock represented by that holder's depositary shares. The depositary
will endeavor, to the extent practicable, to vote the preferred stock
represented by the depositary shares in accordance with these instructions. If
the depositary does not receive instructions from the holders of the depositary
shares, the depositary will abstain from voting the preferred stock that
underlies those depositary shares.

WITHDRAWAL OF PREFERRED STOCK

     If a holder of depositary receipts surrenders those depositary receipts at
the corporate office (as defined in the deposit agreement) of the depositary, or
any other office as the depositary may designate, and pays any taxes, charges or
fees, that holder is entitled to delivery at the corporate office of
certificates evidencing the number of shares of preferred stock, but only in
whole shares, and any money and other property represented by those depositary
receipts. If the depositary receipts we deliver evidence a number of depositary
shares in excess of the number of whole shares of preferred stock to be
withdrawn, the depositary will deliver to us at the same time a new depositary
receipt evidencing that excess number of depositary shares. We do not expect
that there will be any public trading market for the shares of preferred stock
except those represented by the depositary shares.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     Apache and the depositary can agree, at any time, to amend the form of
depositary receipt and any provisions of the deposit agreement. However, if an
amendment has a material adverse effect on the rights of the holders of related
depositary shares, the holders of at least a majority of the depositary shares
then outstanding must first approve the amendment. Every holder of a depositary
receipt at the time an amendment becomes effective will be bound by the amended
deposit agreement. However, subject to any conditions in the deposit agreement
or applicable law, no amendment can impair the right of any holder of a
depositary share to receive shares of the related preferred stock, or any money
or other property represented by the depositary shares, when they surrender
their depositary receipts.

     Unless otherwise specified in the applicable prospectus supplement, the
deposit agreement may be terminated by us or by the depositary if there has been
a final distribution in respect of
                                       16
<PAGE>   20

the preferred stock in connection with any liquidation, dissolution or winding
up of Apache and that distribution has been distributed to the holders of
depositary receipts.

CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and the government charges that
relate solely to the depositary arrangements. We will also pay the charges of
each depositary, including charges in connection with the initial deposit of the
related series of preferred stock, the initial issuance of the depositary
shares, and all withdrawals of shares of the related series of preferred stock.
However, holders of depositary shares will be required to pay transfer and other
taxes and government charges, as provided in the deposit agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time. We may remove the depositary at any
time. Any resignation or removal will take effect when we appoint a successor
depositary. We must appoint the successor depositary within 60 days after
delivery of the notice of resignation or removal. The successor depositary must
be a bank or trust company that has its principal office in the United States
and has a combined capital and surplus of at least $50,000,000.

MISCELLANEOUS

     We will be required to furnish certain information to the holders of the
preferred stock underlying any depositary shares. The depositary, as the holder
of the underlying preferred stock, will forward any report or information it
receives from us to the holders of depositary shares.


     Neither the depositary nor Apache will be liable if its ability to perform
its obligations under the deposit agreement is prevented or delayed by law or
any circumstance beyond its control. Each of Apache and the depositary will be
obligated to use its best judgment and to act in good faith in performing its
duties under the deposit agreement. Each of Apache and the depositary will be
liable only for gross negligence and willful misconduct in performing its duties
under the deposit agreement. They will not be obligated to appear in, prosecute
or defend any legal proceeding with respect to any depositary receipts,
depositary shares or preferred stock unless they receive what they, in their
sole discretion, determine to be a satisfactory indemnity from one or more
holders of the depositary shares. Apache and the depositary will evaluate any
proposed indemnity in order to determine whether the financial protection
afforded by the indemnity is sufficient to reduce each party's risk to a
satisfactory and customary level. Apache and the depositary may rely on the
advice of legal counsel or accountants of their choice. They may also rely on
information provided by persons they believe, in good faith, to be competent,
and on documents they believe, in good faith, to be genuine.


     The applicable prospectus supplement will identify the depositary's
corporate trust office. Unless the prospectus supplement indicates otherwise,
the depositary will act as transfer agent and registrar for depositary receipts,
and if we redeem shares of preferred stock, the depositary will act as
redemption agent for the corresponding depositary receipts.

TITLE

     Apache, each depositary and any agent of Apache or the applicable
depositary may treat the registered owner of any depositary share as the
absolute owner of the depositary shares for all purposes, including making
payment, regardless of whether any payment in respect of the depositary share is
overdue and regardless of any notice to the contrary. See "Book-Entry
Securities" below.

                         DESCRIPTION OF DEBT SECURITIES


     The following description, together with any applicable prospectus
supplement, summarizes all the material terms and provisions of the debt
securities that we may offer under this prospectus and the related trust
indentures. We will issue the senior debt securities under a senior indenture,
dated as of November 2, 1995, as supplemented on October 31, 1996, between us
and The Chase Manhattan Bank, as trustee. We will issue the subordinated debt
securities under a subordinated indenture to be executed in the future by us and
The Chase Manhattan Bank, as trustee. The senior indenture and the subordinated
indenture are together referred to in this prospectus as the "indentures." The
senior debt securities and the subordinated debt securities are collectively
referred to in this prospectus as the "debt securities." The Chase Manhattan
Bank or any successor, in its capacity as trustee under either or both of the
indentures, is referred to as the "trustee" for purposes of this section. The
indentures contain and the debt securities, when issued, will contain additional
important terms and provisions. The indentures are, and the debt securities
prior to their issuance will be, filed as exhibits to the registration statement
that includes this prospectus.


     This summary of the indentures and the debt securities relates to terms and
conditions applicable to the debt securities generally. The particular terms of
any series of debt securities will be summarized in the applicable prospectus
supplement. If indicated in the prospectus supplement, the terms of any series
may differ from the terms summarized below.

     Neither indenture limits the amount of debt securities we may issue under
it, and each provides that additional debt securities of any series may be
issued up to the aggregate principal amount that we authorize from time to time.
Debt securities may also be issued pursuant to the indentures in transactions
exempt from the registration requirements of the Securities Act of 1933. Those
debt securities will not be considered in determining the aggregate amount of
securities issued under this prospectus.

     Unless otherwise indicated in the applicable prospectus supplement, we will
issue the debt securities in denominations of $1,000 or integral multiples of
$1,000.

     Principal and any premium and interest in respect to the debt securities
will be payable, and the debt securities will be transferable, at the corporate
trust office of the trustee, unless we specify otherwise in the applicable
prospectus supplement. At our option, however, payment of interest may be made
by check mailed to the registered holders of the debt securities at their
registered addresses.

     We will describe special U.S. federal income tax and other considerations
relating to debt securities denominated in foreign currencies or units of two or
more foreign currencies in the applicable prospectus supplement.


     Unless we specify otherwise in the applicable prospectus supplement, the
covenants contained in the indentures and the debt securities will not provide
special protection to holders of debt securities if we enter into a highly
leveraged transaction, recapitalization or restructuring. Nothing in the
indentures or the debt securities will in any way limit the amount of
indebtedness or securities that we or our subsidiaries, as defined in the
indenture, may incur or issue.


GENERAL

     The prospectus supplement relating to the particular series of debt
securities being offered will specify whether they are senior or subordinated
debt securities and the amounts, prices and terms of those debt securities.
These terms may include:

     - the designation, aggregate principal amount and authorized denominations
       of the debt securities;

     - the date or dates on which the debt securities will mature;

                                       18
<PAGE>   22

     - the percentage of the principal amount at which the debt securities will
       be issued;

     - the date on which the principal of the debt securities will be payable;

     - whether the debt securities will be issued as registered securities,
       bearer securities or a combination of the two;

     - whether the debt securities will be issued in the form of one or more
       global securities and whether such global securities will be issued in a
       temporary global form or permanent global form;

     - the currency or currencies or currency unit or units of two or more
       currencies in which debt securities are denominated, for which they may
       be purchased, and in which principal and any premium and interest is
       payable;


     - if the currency or currencies or currency unit or units for which debt
       securities may be purchased or in which principal and any premium and
       interest may be paid is at our election or at the election of a
       purchaser, the manner in which an election may be made and its terms;


     - the annual rate or rates, which may be fixed or variable, or the method
       of determining the rate or rates at which the debt securities will bear
       any interest, whether by remarketing, auction, formula or otherwise;

     - the date or dates from which any interest will accrue and the date or
       dates on which such interest will be payable;

     - a description of any provisions providing for redemption, exchange or
       conversion of the debt securities at our option, a holder's option or
       otherwise, and the terms and provisions of such a redemption, exchange or
       conversion;

     - information with respect to book-entry procedures relating to global debt
       securities;

     - any sinking fund terms;

     - whether and under what circumstances we will pay "additional amounts," as
       defined in the indentures, on the debt securities to any holder who is a
       "United States alien," as defined in the indentures, in respect of any
       tax, assessment or governmental charge; the term "interest," as used in
       this prospectus, includes any additional amounts;


     - any modifications or additions to, or deletions of, any of the events of
       default or covenants of Apache with respect to the debt securities that
       are described in this prospectus;


     - if either or both of the sections of the applicable indenture relating to
       defeasance and covenant defeasance are not applicable to the debt
       securities, or if any covenants in addition to or other than those
       specified in the applicable indenture shall be subject to covenant
       defeasance;

     - any deletions from, or modifications or additions to, the provisions of
       the indentures relating to satisfaction and discharge in respect of the
       debt securities;

     - any index or other method used to determine the amount of payments of
       principal of, and any premium and interest on, the debt securities; and

     - any other specific terms of the debt securities.

     We are not obligated to issue all debt securities of any one series at the
same time. The debt securities of any one series may not bear interest at the
same rate or mature on the same date.

     If any of the debt securities are sold for foreign currencies or foreign
currency units or if the principal of, or any premium or interest on, any series
of debt securities is payable in foreign
                                       19
<PAGE>   23

currencies or foreign currency units, we will describe the restrictions,
elections, tax consequences, specific terms and other information with respect
to those debt securities and such foreign currencies or foreign currency units
in the applicable prospectus supplement.


     Other than as described below under "The Senior Indenture Limits Our
Ability to Incur Liens," "The Senior Indenture Limits Our Ability to Engage in
Sale/Leaseback Transactions" and "We Are Obligated to Purchase Debt Securities
upon a Change in Control," and as may be described in the applicable prospectus
supplement, the indentures do not limit our ability to incur indebtedness or
afford holders of debt securities protection in the event of a decline in our
credit quality or if we are involved in a takeover, recapitalization or highly
leveraged or similar transaction.


RANKING

  Senior Debt Securities

     Unless otherwise indicated in the applicable prospectus supplement, our
obligation to pay the principal of, and any premium and interest on, the senior
debt securities will be unsecured and will rank equally with all of our other
unsecured unsubordinated indebtedness.

  Subordinated Debt Securities


     Our obligation to pay the principal of, and any premium and interest on,
any subordinated debt securities will be unsecured and will rank subordinate and
junior in right of payment to all senior indebtedness to the extent provided in
the subordinated indenture and the terms of those subordinated debt securities,
as described below and in any applicable prospectus supplement, which may make
deletions from, or modifications or additions to, the subordination terms
described below.


     Upon any payment or distribution of assets or securities of Apache to
creditors upon any liquidation, dissolution, winding-up, reorganization, or any
bankruptcy, insolvency, receivership or similar proceedings in connection with
any insolvency or bankruptcy proceeding of Apache, the holders of senior
indebtedness will first be entitled to receive payment in full of the senior
indebtedness before the holders of subordinated debt securities will be entitled
to receive any payment or distribution in respect of the subordinated debt
securities.


     No payments on account of principal or any premium or interest in respect
of the subordinated debt securities may be made if there has occurred and is
continuing a default in any payment with respect to senior indebtedness or an
event of default with respect to any senior indebtedness resulting in the
acceleration of its maturity, or if any judicial proceeding is pending with
respect to any default.


     "Indebtedness," for purposes of the subordinated indenture, means:


     - indebtedness for borrowed money or for the unpaid purchase price of real
       or personal property of, or guaranteed by, Apache, other than accounts
       payable arising in the ordinary course of business payable on terms
       customary in the trade;



     - indebtedness secured by any mortgage, lien, pledge, security interest or
       encumbrances of any kind or payable out of the proceeds of production
       from property;



     - indebtedness which is evidenced by mortgages, notes, bonds, securities,
       acceptances or other instruments;



     - indebtedness which must be capitalized as liabilities under generally
       accepted accounting principles;


                                       20
<PAGE>   24


     - liabilities under interest rate swap, exchange, collar or cap agreements
       and all other agreements or arrangements designed to protect against
       fluctuations in interest rates or currency exchange rates;



     - liabilities under commodity hedge, commodity swap, exchange, collar or
       cap agreements, fixed price agreements and all other agreements or
       arrangements designed to protect against fluctuations in oil and gas
       prices;



     - guarantees and endorsements of obligations of others, directly or
       indirectly, and all other repurchase agreements and indebtedness in
       effect guaranteed through an agreement, contingent or otherwise, to
       purchase that indebtedness, or to purchase or sell property, or to
       purchase or sell services, primarily for the purpose of enabling the
       debtor to make payment of the indebtedness or to assure the owner of the
       indebtedness against loss, or to supply funds to or in any manner invest
       in the debtor, or otherwise to assure a creditor against loss (but
       excluding guarantees and endorsements of notes, bills and checks made in
       the ordinary course of business); and



     - indebtedness relative to the amount of all letters of credit;



provided, however, that such term shall not include any amounts included as
deferred credits on the financial statements of Apache and computed in
accordance with generally accepted accounting principles.



     "Senior indebtedness," for purposes of the subordinated indenture, means
all indebtedness, whether outstanding on the date of execution of the
subordinated indenture or thereafter created, assumed or incurred, except
indebtedness ranking equally with the subordinated debt securities or
indebtedness ranking junior to the subordinated debt securities.



     "Indebtedness ranking equally with the subordinated debt securities," for
purposes of the subordinated indenture, means indebtedness, whether outstanding
on the date of execution of the subordinated indenture or thereafter created,
assumed or incurred, to the extent the indebtedness specifically by its terms
ranks equally with and not prior to the subordinated debt securities in the
right of payment upon the happening of the dissolution, winding-up, liquidation
or reorganization of Apache. The securing of any indebtedness otherwise
constituting indebtedness ranking equally with the subordinated debt securities
will not prevent the indebtedness from constituting indebtedness ranking equally
with the subordinated debt securities.


     "Indebtedness ranking junior to the subordinated debt securities," for
purposes of the subordinated indenture, means any indebtedness, whether
outstanding on the date of execution of the subordinated indenture or thereafter
created, assumed or incurred, to the extent the indebtedness by its terms ranks
junior to and not equally with or prior to

     - the subordinated debt securities, and

     - any other indebtedness ranking equally with the subordinated debt
       securities,

in right of payment upon the happening of the dissolution, winding-up,
liquidation or reorganization of Apache. The securing of any indebtedness
otherwise constituting indebtedness ranking junior to the subordinated debt
securities will not prevent the indebtedness from constituting indebtedness
ranking junior to the subordinated debt securities.

INTEREST RATES AND DISCOUNTS

     The debt securities will earn interest at a fixed or floating rate or rates
for the period or periods of time specified in the applicable prospectus
supplement. Unless otherwise specified in the applicable prospectus supplement,
the debt securities will bear interest on the basis of a 360-day year consisting
of twelve 30-day months.

                                       21
<PAGE>   25

     We may sell debt securities at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate that at the time of
issuance is below market rates. Federal income tax consequences and special
considerations that apply to any series will be described in the applicable
prospectus supplement.

EXCHANGE, REGISTRATION AND TRANSFER

     Registered securities of any series that are not global securities will be
exchangeable for other registered securities of the same series and of like
aggregate principal amount and tenor in different authorized denominations. In
addition, if debt securities of any series are issuable as both registered
securities and bearer securities, the holder may choose, upon written request,
and subject to the terms of the applicable indenture, to exchange bearer
securities and the appropriate related coupons of that series into registered
securities of the same series of any authorized denominations and of like
aggregate principal amount and tenor. Bearer securities with attached coupons
surrendered in exchange for registered securities between a regular record date
or a special record date and the relevant date for interest payment shall be
surrendered without the coupon relating to the interest payment date. Interest
will not be payable with respect to the registered security issued in exchange
for that bearer security. That interest will be payable only to the holder of
the coupon when due in accordance with the terms of the indenture. Bearer
securities will not be issued in exchange for registered securities.

     You may present registered securities for registration of transfer,
together with a duly executed form of transfer, at the office of the security
registrar or at the office of any transfer agent designated by us for that
purpose with respect to any series of debt securities and referred to in the
applicable prospectus supplement. This may be done without service charge but
upon payment of any taxes and other governmental charges as described in the
applicable indenture. The security registrar or the transfer agent will effect
the transfer or exchange upon being satisfied with the documents of title and
identity of the person making the request. We have appointed the trustee as
security registrar for each indenture. If a prospectus supplement refers to any
transfer agents initially designated by us with respect to any series of debt
securities in addition to the security registrar, we may at any time rescind the
designation of any of those transfer agents or approve a change in the location
through which any of those transfer agents acts. However, if debt securities of
a series are issuable solely as registered securities, we will be required to
maintain a transfer agent in each place of payment for that series, and if debt
securities of a series are issuable as bearer securities, we will be required to
maintain a transfer agent in a place of payment for that series located in
Europe in addition to the security registrar. We may at any time designate
additional transfer agents with respect to any series of debt securities.

     In the event of any redemption, we will not be required to:

     - issue, register the transfer of or exchange debt securities of any series
       during a period beginning at the opening of business 15 days before any
       selection of debt securities of that series to be redeemed and ending at
       the close of business on the day of mailing of the relevant notice of
       redemption; or

     - register the transfer of or exchange any registered security, or portion
       thereof, called for redemption, except the unredeemed portion of any
       registered security being redeemed in part.

PAYMENT AND PAYING AGENTS

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal of, and any premium and interest on, bearer securities will
be payable in accordance with any applicable laws and regulations, at the
offices of those paying agents outside the United States that we may designate
at various times. We will make interest payments on bearer securities and

                                       22
<PAGE>   26

the attached coupons on any interest payment date only against surrender of the
coupon relating to that interest payment date. No payment with respect to any
bearer security will be made at any of our offices or agencies in the United
States by check mailed to any U.S. address or by transfer to an account
maintained with a bank located in the United States. If, however, but only if,
payment in U.S. dollars of the full amount of principal of, and any premium and
interest on, bearer securities denominated and payable in U.S. dollars at all
offices or agencies outside the United States is illegal or effectively
precluded by exchange controls or other similar restrictions, then those
payments will be made at the office of our paying agent in the Borough of
Manhattan, The City of New York.

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal of, and any premium and interest on, registered securities
will be made at the office of the paying agent or paying agents that we
designate at various times. However, at our option, we may make interest
payments by check mailed to the address, as it appears in the security register,
of the person entitled to the payments. Unless we specify otherwise in the
applicable prospectus supplement, we will make payment of any installment of
interest on registered securities to the person in whose name that registered
security is registered at the close of business on the regular record date for
such interest.

     Unless we specify otherwise in the applicable prospectus supplement, the
Corporate Trust Office of the trustee in the Borough of Manhattan, The City of
New York, will be designated:

     - as our sole paying agent for payments with respect to debt securities
       that are issuable solely as registered securities; and

     - as our paying agent in the Borough of Manhattan, The City of New York,
       for payments with respect to debt securities, subject to the limitation
       described above in the case of bearer securities, that are issuable
       solely as bearer securities or as both registered securities and bearer
       securities.

     We will name any paying agents outside the United States and any other
paying agents in the United States initially designated by us for the debt
securities in the applicable prospectus supplement. We may at any time designate
additional paying agents or rescind the designation of any paying agent or
approve a change in the office through which any paying agent acts. However, if
debt securities of a series are issuable solely as registered securities, we
will be required to maintain a paying agent in each place of payment for that
series. If debt securities of a series are issuable as bearer securities, we
will be required to maintain:

     - a paying agent in the Borough of Manhattan, The City of New York, for
       payments with respect to any registered securities of the series and for
       payments with respect to bearer securities of the series in the
       circumstance described above, but not otherwise; and

     - a paying agent in a place of payment located outside the United States
       where debt securities of that series and any attached coupons may be
       presented and surrendered for payment.

     However, if the debt securities of that series are listed on the London
Stock Exchange, the Luxembourg Stock Exchange or any other stock exchange
located outside the United States, and if the stock exchange requires it, we
will maintain a paying agent in London or Luxembourg or any other required city
located outside the United States for those debt securities.

     All monies we pay to a paying agent for the payment of principal of, and
any premium or interest on, any debt security or coupon that remains unclaimed
at the end of two years after becoming due and payable will be repaid to us.
After that time, the holder of the debt security or coupon will look only to us
for payments out of those repaid amounts.

GLOBAL SECURITIES


     The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that we will deposit with a depository
identified in the applicable prospectus supplement. Global securities may be
issued in either registered or bearer form and in either temporary or permanent
form. Unless and until it is exchanged in whole or in part for the individual
debt securities it represents, a global security may not be transferred except
as a whole:



     - by the applicable depositary to a nominee of the depository;



     - by any nominee to the depository itself or another nominee; or



     - by the depositary or any nominee to a successor depository or any nominee
       of the successor.



     To the extent not described below and under the heading "Book-Entry
Securities," we will describe the terms of the depository arrangement with
respect to a series of debt securities in the applicable prospectus supplement.
We anticipate that the following provisions will generally apply to depository
arrangements.



     As long as the depository for a global security, or its nominee, is the
registered owner of that global security, the depository or nominee will be
considered the sole owner or holder of the debt securities represented by the
global security for all purposes under the applicable indenture. Except as
provided under "Book-Entry Securities" or in any applicable prospectus
supplement, owners of beneficial interests in a global security:


     - will not be entitled to have any of the underlying debt securities
       registered in their names;

     - will not receive or be entitled to receive physical delivery of any of
       the underlying debt securities in definitive form; and

     - will not be considered the owners or holders under the indenture relating
       to those debt securities.


     The laws of some states require that certain purchasers of securities take
physical delivery of securities in definitive form. These laws may impair your
ability to transfer beneficial interests in a global security.



     Payments of principal of, and any premium and interest on, individual debt
securities represented by a global security registered in the name of a
depository or its nominee will be made to the depository or its nominee as the
registered owner of the global security representing such debt securities.
Neither we, the trustee, any paying agent nor the registrar for the debt
securities will be responsible for any aspect of the records relating to or
payments made by the depository or any participants on account of beneficial
interests of the global security.



     For a description of the depository arrangements for global securities held
by The Depository Trust Company, see "Book-Entry Securities."


THE SENIOR INDENTURE LIMITS OUR ABILITY TO INCUR LIENS


     Unless we specify otherwise in the applicable prospectus supplement, the
senior indenture provides that neither we nor any of our subsidiaries may issue,
assume or guarantee any notes, bonds, debentures or other similar evidences of
indebtedness for money borrowed that are secured by a mortgage, lien, pledge,
security interest or other encumbrance -- defined in the indenture as
"liens" -- upon any of our property unless we provide that any and all senior
debt


                                       24
<PAGE>   28

securities then outstanding shall be secured by a lien equally and ratably with
any and all other obligations by the lien. The restrictions on liens will not,
however, apply to:

     - liens existing on the date of the senior indenture or provided for under
       the terms of agreements existing on the date thereof;

     - liens securing all or part of the cost of exploring, producing,
       gathering, processing, marketing, drilling or developing any of our or
       our subsidiaries' properties, or securing indebtedness incurred to
       provide funds therefor or indebtedness incurred to finance all or part of
       the cost of acquiring, constructing, altering, improving or repairing any
       such property or assets, or securing indebtedness incurred to provide
       funds therefor;

     - liens securing only indebtedness owed by one of our subsidiaries to us
       and/or to one or more of our other subsidiaries;

     - liens on the property of any corporation or other entity existing at the
       time it becomes our subsidiary;

     - liens on any property to secure indebtedness incurred in connection with
       the construction, installation or financing of pollution control or
       abatement facilities or other forms of industrial revenue bond financing
       or indebtedness issued or guaranteed by the United States, any state or
       any department, agency or instrumentality of either or indebtedness
       issued to or guaranteed for the benefit of a foreign government, any
       state or any department, agency or instrumentality of either or an
       international finance agency or any division or department thereof,
       including the World Bank, the International Finance Corp. and the
       Multilateral Investment Guarantee Agency;

     - any extension, renewal or replacement or successive extensions, renewals
       or replacements of any lien referred to in the foregoing clauses that
       existed on the date of the senior indenture;

     - certain other liens incurred in the ordinary course of business; or

     - liens which secure "limited recourse indebtedness," as defined in the
       senior indenture.

     In addition, the following types of transactions, among others, shall not
be deemed to create indebtedness secured by liens:

     - the sale or other transfer of crude oil, natural gas or other petroleum
       hydrocarbons in place for a period of time until, or in an amount such
       that, the transferee will receive as a result of the transfer a specified
       amount of money or of such crude oil, natural gas or other petroleum
       hydrocarbons;

     - the sale or other transfer of any other interest in property of the
       character commonly referred to as a production payment, overriding
       royalty, forward sale or similar interest; and


     - liens required by any contract or statute in order to permit us or one of
       our subsidiaries to perform any contract or subcontract made with or at
       the request of the U.S. government or any foreign government or
       international finance agency, any state or any department thereof, or any
       agency or instrumentality of either, or to secure partial, progress,
       advance or other payments to us or one of our subsidiaries by any of
       these entities pursuant to the provisions of any contract or statute.


                                       25

THE SENIOR INDENTURE LIMITS OUR ABILITY TO ENGAGE IN SALE/LEASEBACK TRANSACTIONS

     Unless we specify otherwise in the applicable prospectus supplement, the
senior debt indenture provides that neither we nor any of our subsidiaries will
enter into any arrangement with any person, other than us or one of our
subsidiaries, to lease any property to ourselves or a subsidiary of ours for
more than three years. For the restriction to apply, we or one of our
subsidiaries must sell or plan to sell the property to the person leasing it to
us or our subsidiary or to another person to which funds have been or are to be
advanced on the security of the leased property. The limitation does not apply
where:

     - either we or our subsidiary would be entitled to create debt secured by a
       lien on the property to be leased in a principal amount equal to or
       exceeding the value of that sale/leaseback transaction;

     - since the date of the senior indenture and within a period commencing six
       months prior to the consummation of that arrangement and ending six
       months after the consummation of the arrangement, we have or our
       subsidiary has expended for any property an amount up to the net proceeds
       of that arrangement, including amounts expended for the acquisition,
       exploration, drilling or development thereof, and for additions,
       alterations, improvements and repairs to the property, and we designate
       such amount as a credit against that arrangement, with any of that amount
       not being so designated to be applied as set forth in the next item; or

     - during or immediately after the expiration of the 12 months after the
       effective date of that transaction, we apply to the voluntary redemption,
       defeasance or retirement of the senior debt securities and/or other
       senior indebtedness, as defined in the senior indenture, an amount equal
       to the greater of the net proceeds of the sale or transfer of the
       property leased in that transaction or the fair value of such property at
       the time of entering into such transaction, in either case adjusted to
       reflect the remaining term of the lease and any amount we utilize as set
       forth in the prior item; the amount will be reduced by the principal
       amount of senior indebtedness we voluntarily retire within that 12-month
       period.

EACH INDENTURE INCLUDES EVENTS OF DEFAULT

     Unless otherwise specified in the applicable prospectus supplement, any one
of the following events will constitute an "event of default" under each
indenture with respect to the debt securities of any series issued under that
indenture:

     - if we fail to pay any interest on any debt security of that series when
       due, and the failure continues for 30 days;

     - if we fail to pay principal of or any premium on the debt securities of
       that series when due and payable, either at maturity or otherwise;

     - if we fail to perform or we breach any of our other covenants or
       warranties in the applicable indenture or in the debt securities of that
       series -- other than a covenant or warranty included in the applicable
       indenture solely for the benefit of a series of securities other than the
       debt securities of that series -- and that breach of failure continues
       for 60 days after written notice as provided in the applicable indenture;

     - certain events of bankruptcy, insolvency or reorganization involving us
       or any of our subsidiaries; and

     - any other event of default provided with respect to the debt securities
       of that series.

                                       26
<PAGE>   30


     Unless otherwise specified in the applicable prospectus supplement, either
of the following two events will also constitute an "event of default" under the
senior indenture with respect to any senior debt securities:


     - if any of our or any of our subsidiaries' indebtedness, as defined in the
       senior indenture, in excess of an aggregate of $25,000,000 in principal
       amount is accelerated under any event of default as defined in any
       mortgage, indenture or instrument and the acceleration has not been
       rescinded or annulled within 30 days after written notice as provided in
       the senior indenture has been given specifying such event of default and
       requiring us to cause that acceleration to be rescinded or annulled; or

     - if we or any of our subsidiaries fail to pay, bond or otherwise discharge
       within 60 days of entry, a judgment, court order or uninsured monetary
       damage award against us in excess of an aggregate of $25,000,000 which is
       not stayed on appeal or otherwise being appropriately contested in good
       faith.

     If an event of default with respect to the debt securities of any series,
other than an event of default described in the item above pertaining to certain
events of bankruptcy, insolvency or reorganization, occurs and is continuing,
either the trustee or the holders of at least 25% in aggregate principal amount
of the outstanding debt securities of that series may declare the principal
amount of the debt securities of that series to be due and payable immediately.
At any time after a declaration of acceleration has been made, but before a
judgment or decree for payment of money has been obtained by the trustee, and
subject to applicable law and certain other provisions of the applicable
indenture, the holders of a majority in aggregate principal amount of the debt
securities of that series may, under certain circumstances, rescind and annul
such acceleration. If an event of default occurs pertaining to certain events of
bankruptcy, insolvency or reorganization, the principal amount and accrued
interest -- or a lesser amount as provided for in the debt securities of that
series -- shall be immediately due and payable without any declaration or other
act by the trustee or any holder.


     Within 90 days after the occurrence of any event of default under an
indenture with respect to the debt securities of any series issued under that
indenture, the trustee must transmit notice of the event of default to the
holders of the debt securities of that series unless the event of default has
been cured or waived. The trustee may withhold the notice, however, except in
the case of a payment default, if and so long as the board of directors, the
executive committee or a trust committee of directors or responsible officers of
the trustee has in good faith determined that the withholding of the notice is
in the interest of the holders of debt securities of that series.


     If an event of default occurs and is continuing with respect to the debt
securities of any series, the trustee may in its discretion proceed to protect
and enforce its rights and the rights of the holders of debt securities of that
series by all appropriate judicial proceedings.


     Subject to the duty of the trustee during any default to act with the
required standard of care, the trustee is under no obligation to exercise any of
its rights or powers under an indenture at the request or direction of any of
the holders of debt securities issued under that indenture, unless the holders
offer the trustee reasonable indemnity. Subject to indemnifying the trustee, and
subject to applicable law and certain other provisions of each indenture, the
holders of a majority in aggregate principal amount of the outstanding debt
securities of a series issued under that indenture may 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 the
debt securities of that series.


WE ARE OBLIGATED TO PURCHASE DEBT SECURITIES UPON A CHANGE IN CONTROL

     If a change in control, as defined in each indenture, occurs, we must mail
within 15 days a written notice regarding the change in control to the trustee
and to every holder of the debt

                                       27
<PAGE>   31

securities of each series issued under that indenture. The notice must also be
published at least once in an authorized newspaper, as defined in each
indenture, and must state:

     - the event causing the change in control and the date of the event;

     - the date by which notice of the change in control is required by the
       applicable indenture to be given;

     - the date, 35 business days after the occurrence of the change in control,
       by which we must purchase debt securities we are obligated to purchase
       pursuant to the selling holder's exercise of rights on change in control;

     - the price we must pay for the debt securities we are obligated to
       purchase;

     - the name and address of the trustee;

     - the procedure for surrendering debt securities to the trustee or other
       designated office or agent for payment;

     - a statement of our obligation to make prompt payment on proper surrender
       of the debt securities;

     - the procedure for holders' exercise of rights of sale of the debt
       securities; and

     - the procedures by which a holder may withdraw such a notice after it is
       given.

     After we give this notice we will be obligated, at the election of each
holder, to purchase the applicable debt securities. Under each indenture, a
change in control is deemed to have occurred when:

     - any event requiring the filing of any report under or in response to
       Schedule 13D or 14D-1 pursuant to the Securities Exchange Act of 1934
       disclosing beneficial ownership of either 50% or more of our common stock
       then outstanding or 50% or more of the voting power of our voting stock
       then outstanding;

     - the completion of any sale, transfer, lease, or conveyance of our
       properties and assets substantially as an entirety to any person or
       persons that is not our subsidiary, as those terms are defined in each
       indenture; or

     - the completion of a consolidation or merger of Apache with or into any
       other person or entity in a transaction in which either we are not the
       sole surviving corporation or our common stock existing before the
       transaction is converted into cash, securities or other property and in
       which those exchanging our common stock do not, as a result of the
       transaction, receive either 75% or more of the survivor's common stock or
       75% or more of the voting power of the survivor's voting stock.

     We will not purchase any debt securities if there has occurred and is
continuing an event of default under either indenture, other than default in
payment of the purchase price payable for the debt securities upon change in
control. In connection with any purchase of debt securities after a change in
control, we will comply with all federal and state securities laws, including,
specifically, Rule 13e-4, if applicable, of the Securities Exchange Act, and any
related Schedule 13E-4 required to be submitted under that rule.

                                       28
<PAGE>   32

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     We may discharge certain obligations to holders of any series of debt
securities that have not already been delivered to the trustee for cancellation
and that:

     - have become due and payable;

     - will become due and payable within one year; or

     - are scheduled for redemption within one year.

To discharge the obligations with respect to a series of debt securities, we
must deposit with the trustee, in trust, an amount of funds in U.S. dollars or
in the foreign currency in which those debt securities are payable sufficient to
pay the entire amount of principal of, and any premium or interest on, those
debt securities to the date of the deposit if those debt securities have become
due and payable or to the maturity of the debt securities, as the case may be.

     Unless we specify otherwise in the applicable prospectus supplement, we may
elect

     - to defease and be discharged from any and all obligations with respect to
       those debt securities, which we refer to as "legal defeasance"; or

     - with respect to any debt securities, to be released from our covenant
       obligations, as may be provided for under Section 301 of either
       indenture, which we refer to as "covenant defeasance"; or,


     - with respect to any senior debt securities, to be released from our
       obligations under the covenants described above in "The Senior Indenture
       Limits Our Ability to Incur Liens" and "The Senior Indenture Limits Our
       Ability to Engage in Sale/Leaseback Transactions," which we also refer to
       as "covenant defeasance."


     In the case of legal defeasance we will still retain some obligations in
respect of the debt securities, including our obligations:

     - to pay additional amounts, if any, upon the occurrence of certain events
       of taxation, assessment or governmental charge with respect to payments
       on the debt securities;

     - to register the transfer or exchange of the debt securities;

     - to replace temporary or mutilated, destroyed, lost or stolen debt
       securities; and

     - to maintain an office or agency with respect to the debt securities and
       to hold monies for payment in trust.

     After a covenant defeasance, any omission to comply with the obligations or
covenants that have been defeased shall not constitute a default or an event of
default with respect to the debt securities.

     To elect either legal defeasance or covenant defeasance we must deposit
with the trustee, in trust, an amount, in U.S. dollars or in the foreign
currency in which the relevant debt securities are payable at stated maturity,
or in government obligations, as defined below, or both, applicable to such debt
securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of and any premium and interest on those debt securities on their
scheduled due dates.

                                       29
<PAGE>   33

     In addition, we can only elect legal defeasance or covenant defeasance if,
among other things:

     - the applicable defeasance does not result in a breach or violation of, or
       constitute a default under, the applicable indenture or any other
       material agreement or instrument to which we are a party or by which we
       are bound;

     - no default or event of default with respect to the debt securities to be
       defeased shall have occurred and be continuing on the date of the
       establishment of the trust and, with respect to legal defeasance only, at
       any time during the period ending on the 91st day after the date of the
       establishment of the trust; and

     - we have delivered to the trustee an opinion of counsel to the effect that
       the holders of the debt securities will not recognize income, gain or
       loss for U.S. federal income tax purposes as a result of the defeasance
       and will be subject to U.S. federal income tax on the same amounts, in
       the same manner and at the same times as would have been the case if the
       defeasance had not occurred, and the opinion of counsel, in the case of
       legal defeasance, must refer to and be based upon a letter ruling of the
       Internal Revenue Service received by us, a Revenue Ruling published by
       the Internal Revenue Service or a change in applicable U.S. federal
       income tax law occurring after the date of the applicable indenture.


     Each indenture deems a foreign currency to be any currency, currency unit
or composite currency issued by the government of one or more countries other
than the United States or by any recognized confederation or association of
governments.


     Each indenture defines government obligations as securities which are not
callable or redeemable at the option of the issuer or issuers and are:

     - direct obligations of the United States or the government or the
       governments in the confederation which issued the foreign currency in
       which the debt securities of a particular series are payable, for the
       payment of which its full faith and credit is pledged; or

     - obligations of a person or entity controlled or supervised by and acting
       as an agency or instrumentality of the United States or the government or
       governments which issued the foreign currency in which the debt
       securities of a particular series are payable, the timely payment of
       which is unconditionally guaranteed as a full faith and credit obligation
       by the United States or that other government or governments.

Government obligations also include a depositary receipt issued by a bank or
trust company as custodian with respect to any government obligation described
above or a specific payment of interest on or principal of or any other amount
with respect to any government obligation held by that custodian for the account
of the holder of such depositary receipt, as long as, except as required by law,
that custodian is not authorized to make any deduction from the amount payable
to the holder of the depositary receipt from any amount received by the
custodian with respect to the government obligation or the specific payment of
interest on or principal of or any other amount with respect to the government
obligation evidenced by the depositary receipt.


     Unless otherwise specified in the applicable prospectus supplement, if,
after we have deposited funds and/or government obligations to effect legal
defeasance or covenant defeasance with respect to debt securities of any series,
either:


     - the holder of a debt security of that series is entitled to, and does,
       elect to receive payment in a currency other than that in which such
       deposit has been made in respect of that debt security; or

                                       30
<PAGE>   34

     - a conversion event, as defined below, occurs in respect of the foreign
       currency in which the deposit has been made,

the indebtedness represented by that debt security shall be deemed to have been,
and will be, fully discharged and satisfied through the payment of the principal
of, and any premium and interest on, that debt security as that debt security
becomes due out of the proceeds yielded by converting the amount or other
properties so deposited in respect of that debt security into the currency in
which that debt security becomes payable as a result of the election or
conversion event based on:

     - in the case of payments made pursuant to the first of the two items in
       the list above, the applicable market exchange rate for the currency in
       effect on the second business day prior to the date of the payment; or

     - with respect to a conversion event, the applicable market exchange rate
       for such foreign currency in effect, as nearly as feasible, at the time
       of the conversion event.

     Each indenture defines a "conversion event" as the cessation of use of:


     - a foreign currency other than the ECU or euro both by the government of
       the country or the confederation which issued such foreign currency and
       for the settlement of transactions by a central bank or other public
       institutions of or within the international banking community;



     - the ECU or euro both within the European Monetary System and for the
       settlement of transactions by public institutions of or within the
       European Monetary System; or



     - any currency unit or composite currency other than the ECU or euro for
       the purposes for which it was established.


Unless otherwise provided in the applicable prospectus supplement, all payments
of principal of, and any premium and interest on, any debt security that are
payable in a foreign currency that ceases to be used by the government or
confederation of issuance shall be made in U.S. dollars.

     If we effect a covenant defeasance with respect to any debt securities and
the debt securities are declared due and payable because of the occurrence of
any event of default other than an event of default with respect to which there
has been covenant defeasance, the amount in the foreign currency in which the
debt securities are payable, and government obligations on deposit with the
trustee, will be sufficient to pay amounts due on the debt securities at the
time of the stated maturity but may not be sufficient to pay amounts due on the
debt securities at the time of the acceleration resulting from the event of
default. However, we would remain liable for payment of the amounts due at the
time of acceleration.

     The applicable prospectus supplement may further describe the provisions,
if any, permitting defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the debt
securities of or within a particular series.

     Under each indenture, we are required to furnish to the trustee annually a
statement as to our performance of certain of our obligations under the
indenture and as to any default in such performance. We are also required to
deliver to the trustee, within five days after occurrence thereof, written
notice of any event which after notice or lapse of time or both would constitute
an event of default.

MODIFICATION AND WAIVER


     We and the trustee may, without the consent of holders, modify provisions
of each indenture for certain purposes, including, among other things, curing
ambiguities and maintaining


                                       31
<PAGE>   35


the qualification of the applicable indenture under the Trust Indenture Act. We
and the trustee may modify certain other provisions of each indenture with the
consent of the holders of not less than two-thirds, in the case of the senior
indenture, or a majority, in the case of the subordinate indenture, in aggregate
principal amount of the debt securities of each series issued under that
indenture affected by the modification. However, the provisions of either
indenture may not be modified without the consent of the holder of each debt
security affected thereby if the modification would:



     - change the stated maturity or any installment of the principal of, or any
       premium or interest on, or any installment of principal, or any
       additional amounts with respect to, any debt security issued under that
       indenture;


     - reduce the principal amount of, or premium or interest on, or any
       additional amounts with respect to, any debt security issued under that
       indenture;

     - change the coin or currency in which any debt security issued under that
       indenture or any premium or any interest on that debt security or any
       additional amounts with respect to that debt security is payable;

     - if the debt securities are convertible or exchangeable, modify the
       conversion or exchange provision in a manner adverse to holders of that
       debt security;


     - in the case of a subordinated debt security, modify any of the
       subordination provisions in a manner adverse to holders of that debt
       security;


     - impair the right to institute suit for the enforcement of any payment on
       or after the stated maturity of any debt securities issued under that
       indenture or, in the case of redemption, exchange or conversion, if
       applicable, on or after the redemption, exchange or conversion date or,
       in the case of repayment at the option of any holder, if applicable, on
       or after the date for repayment or in the case of a change in control,
       after the change in control purchase date;

     - reduce the percentage and principal amount of the outstanding debt
       securities, the consent of whose holders is required under that indenture
       in order to take certain actions;

     - change any of our obligations to maintain an office or agency in the
       places and for the purposes required by that indenture; or

     - modify any of the above provisions.

     The holders of at least a majority in aggregate principal amount of debt
securities of any series issued under one of the indentures may, on behalf of
the holders of all debt securities of that series, waive our compliance with
certain restrictive provisions of that indenture. The holders of not less than a
majority in aggregate principal amount of debt securities of any series issued
under one of the indentures may, on behalf of all holders of debt securities of
that series, waive any past default and its consequences under that indenture
with respect to the debt securities of that series, except:

     - a payment default with respect to debt securities of that series; or

     - a default of a covenant or provision of that indenture that cannot be
       modified or amended without the consent of the holder of the debt
       securities of that series.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may, without the consent of the holders of the debt securities,
consolidate or merge with or into, or convey, transfer or lease our properties
and assets substantially as an entirety to, any person that is a corporation,
limited liability company, partnership or trust organized and validly existing
under the laws of any domestic jurisdiction. We may also permit any of those
persons to

                                       32
<PAGE>   36

consolidate with or merge into us or convey, transfer or lease its properties
and assets substantially as an entirety to us, as long as:

     - any successor person assumes our obligations on the debt securities;


     - no event of default under the applicable indenture has occurred and is
       continuing after giving effect to the transaction;



     - no event which, after notice or lapse of time or both, would become an
       event of default under the applicable indenture has occurred and is
       continuing after giving effect to the transaction; and


     - certain other conditions are met.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES

     The following applies only in the event that debt securities are held by an
Apache Trust.

     To the extent that any action under any debt securities held by an Apache
Trust is entitled to be taken by the holders of at least a specified percentage
of those debt securities, and unless otherwise specified in the applicable
prospectus supplement, holders of the trust preferred securities issued by that
Apache Trust may take action if the action is not taken by the property trustee
of that Apache Trust. Notwithstanding the foregoing, if an event of default
under those debt securities has occurred and is continuing and is attributable
either to:

     - the failure of Apache to pay the principal of, or any premium or interest
       on, those debt securities on the due date; or


     - the failure by Apache to deliver the required securities or other
       property upon an appropriate conversion or exchange election, if any,


and an event of default has occurred and is continuing under the applicable
trust agreement, a holder of the related trust preferred securities may
institute a direct action.


     A "direct action" is a legal proceeding directly against Apache for
enforcement of payment to the holder of trust preferred securities issued by an
Apache Trust of the principal of or any premium or interest on the debt
securities held by that trust having a principal amount equal to the liquidation
amount of those trust preferred securities held by that holder or for
enforcement of any conversion or exchange rights, as the case may be. Apache may
not amend an indenture to remove this right to bring a direct action without the
prior written consent of the holders of all of the trust preferred securities
outstanding that have an interest in the related debt securities. If the right
to bring a direct action is removed, the Apache Trusts may become subject to the
reporting obligations under the Securities Exchange Act. Notwithstanding any
payments made to a holder of trust preferred securities by Apache in connection
with a direct action, Apache will remain obligated to pay the principal of, and
any premium and interest on, the related debt securities, and Apache will be
subrogated to the rights of the holders of those trust preferred securities with
respect to payments on the trust preferred securities to the extent of any
payments made by Apache to the holder in any direct action.


     The holders of the trust preferred securities will not be able to exercise
directly any remedies, other than those set forth in the preceding paragraph,
available to the holders of the related debt securities unless an event of
default has occurred and is continuing under the applicable trust agreement. See
"Description of Trust Preferred Securities -- Events of Default; Notice" below.

                   DESCRIPTION OF TRUST PREFERRED SECURITIES


     Each Apache Trust will issue under its trust agreement only one series of
trust preferred securities, which will represent beneficial interests in that
Apache Trust. Each Apache Trust will qualify its trust agreement under the Trust

Indenture Act. This summary of certain terms and provisions of the trust
preferred securities and the trust agreement does not purport to be complete and
is subject to, and is qualified in its entirety by reference to, all of the
provisions of the trust preferred securities and the trust agreement, including
the definitions of certain terms, and those made a part of the trust agreement
by the Trust Indenture Act. A form of trust agreement is, and the terms and
conditions of trust securities and forms thereof will be, filed as exhibits to
the registration statement that includes this prospectus.


     Each Apache Trust will describe the specific terms of the trust preferred
securities it is offering in the applicable prospectus supplement, including:


     - the designation, number, purchase price and liquidation amount, if any,
       of the trust preferred securities;

       for the trust preferred securities and, if applicable, any deferral
       provisions;

       payable;



     - the liquidation amount per trust preferred security which will be paid
       out of the assets of that Apache Trust to the holders upon voluntary or
       involuntary dissolution and liquidation of that trust;



     - the obligation or right, if any, of that Apache Trust to purchase or
       redeem its trust preferred securities, whether pursuant to a sinking fund
       or otherwise, and the price or prices at which, the date or dates on
       which or period or periods within which and the terms and conditions upon
       which, it will or may purchase or redeem, in whole or in part, the trust
       preferred securities pursuant to its obligation or right to purchase or
       redeem;



     - the terms and conditions, if any, upon which the trust preferred
       securities may be converted or exchanged, in addition to the
       circumstances described herein, into other securities or property, or a
       combination of the foregoing;


     - the obligation or right, if any, of Apache, that Apache Trust or any
       other party to liquidate that Apache Trust and any terms and conditions
       of such liquidation;

     - the voting rights, if any, of the holders;

     - if applicable, any securities exchange upon which the trust preferred
       securities will be listed;

     - if applicable, a description of any remarketing, auction or other similar
       arrangements;

     - whether the trust preferred securities are issuable in book-entry only
       form and, if so, the identity of the depositary and disclosure relating
       to the depositary arrangements; and

     - any other rights, preferences, privileges, limitations or restrictions of
       the trust preferred securities consistent with the trust agreement or
       with applicable law, which may differ from those described herein.

                                       34
<PAGE>   38

     Each Apache Trust will also describe certain material United States federal
income tax considerations applicable to any offering of trust preferred
securities in the applicable prospectus supplement.

     If indicated in the applicable prospectus supplement, the terms of an
Apache Trust may differ from the terms summarized below.

GENERAL


     The trust preferred securities of each Apache Trust will rank equally, and
payments will be made on the trust preferred securities proportionately, with
the trust common securities of each Apache Trust except as described under
"-- Subordination of Trust Common Securities." Apache Trust will use the
proceeds from the sale of trust preferred securities and trust common securities
to purchase an aggregate principal amount of debt securities of Apache equal to
the aggregate liquidation amount of those trust preferred securities and trust
common securities. The property trustee of each Apache Trust will hold legal
title to the debt securities for the benefit of the holders of the related trust
securities. In addition, Apache will execute a guarantee for the benefit of the
holders of the related trust preferred securities. The guarantees will not
guarantee payment of distributions or amounts payable or securities or other
property deliverable, if any, on redemption, repayment, conversion or exchange
of the trust preferred securities or liquidation of an Apache Trust when the
trust does not have funds or other property legally available for payment or
delivery. See "Description of Trust Preferred Securities Guarantees."



     The revenue of an Apache Trust available for distribution to holders of its
trust preferred securities will be limited to payments under the related debt
securities and any other assets held by that Apache Trust. If Apache fails to
make a required payment in respect of those debt securities or any other assets,
that Apache Trust will not have sufficient funds to make the related payments,
including distributions, in respect of its trust preferred securities.


SUBORDINATION OF TRUST COMMON SECURITIES


     Each Apache Trust will pay distributions on, and the applicable redemption
price of, and any other amounts payable or property deliverable under, the trust
securities it issues equally among its trust preferred securities and its trust
common securities based on their respective liquidation amounts; provided,
however, that if on any distribution date, redemption date, repayment date or
conversion or exchange date, or upon liquidation or an event of default under
the debt securities held by that Apache Trust or any other event of default
under the trust agreement has occurred and is continuing, that Apache Trust will
not pay any distribution on, or applicable redemption or repayment price of, or
convert or exchange any of its trust common securities, and will not make any
other payment on account of the redemption, repayment, conversion, exchange,
liquidation or other acquisition of the trust common securities, unless payment
in full in cash of all accumulated distributions on all of the outstanding trust
preferred securities of that Apache Trust for all distribution periods
terminating on or before the redemption, repayment, conversion, exchange,
liquidation or other acquisition, and, in the case of payment of the applicable
redemption or repayment price, the full amount of the redemption or repayment
price, will have been made or provided for and, in the case of conversion or
exchange, that the trust preferred securities have been converted or exchanged
in full and other amounts payable have been paid. The property trustee will
apply all available funds first to the payment in full in cash of all
distributions on, or the applicable redemption price of, the trust preferred
securities issued by that Apache Trust then due and payable.


     Until any event of default under the trust agreement for an Apache Trust
has been cured, waived or otherwise eliminated, the property trustee will act
solely on behalf of the holders of the trust preferred securities of that Apache
Trust and not on behalf of Apache as the direct or indirect trust common
securities owner, and only the holders of the trust preferred securities

                                       35
<PAGE>   39

issued by that Apache Trust will have the right to direct the property trustee
to act on their behalf.

EVENTS OF DEFAULT; NOTICE


     The occurrence of an event of default under the debt securities and any
other assets held by an Apache Trust will constitute an event of default under
the trust agreement for that Apache Trust. Within 90 business days after the
occurrence of an event of default actually known to the property trustee, the
property trustee will transmit notice of that event of default to the holders of
the trust preferred securities of that Apache Trust, the administrative trustees
and Apache, as sponsor, unless the event of default shall have been cured or
waived.



     For a discussion of the limited circumstances in which holders of trust
preferred securities may bring a direct action against Apache under the debt
securities, see "Description Of Debt Securities -- Enforcement of Certain Rights
by Holders of Trust Preferred Securities." The applicable prospectus supplement
may describe additional events of default under the trust agreement.


REMOVAL OF TRUSTEES


     Unless an event of default under the debt securities held by an Apache
Trust has occurred and is continuing, Apache, as the direct or indirect owner of
trust common securities of that Apache Trust, may remove the property trustee,
the Delaware trustee and the administrative trustees at any time. If an event of
default under the debt securities held by an Apache Trust has occurred and is
continuing, only the holders of a majority in liquidation amount of the
outstanding trust preferred securities of that Apache Trust may remove and
replace the property trustee and the Delaware trustee for that Apache Trust. In
no event will the holders of the trust preferred securities have the right to
vote to appoint, remove or replace the administrative trustees, which voting
rights are vested exclusively in Apache as the direct or indirect trust common
securities owner. No resignation or removal of a property or Delaware trustee,
and no appointment of a successor to that trustee, will be effective until the
acceptance of appointment by the successor trustee in accordance with the
provisions of the applicable trust agreement.


MERGER OR CONSOLIDATION OF PROPERTY OR DELAWARE TRUSTEES


     Any person into which the property trustee or the Delaware trustee 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 will be a party, or any person succeeding to all
or substantially all the corporate trust business of the property trustee or the
Delaware trustee, will be the successor of the property trustee or the Delaware
trustee under the trust agreement, provided that the person will be otherwise
qualified and eligible.


MERGERS, CONVERSIONS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF AN APACHE
TRUST


     An Apache Trust may not merge with or into, convert into, consolidate,
amalgamate, 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,
except as described below or as otherwise described in the applicable prospectus
supplement. An Apache Trust may, at the request of Apache, as sponsor, with the
consent of the administrative trustees but without the consent of the holders of
its trust preferred securities, the Delaware trustee or the property trustee,
merge with or into, convert


                                       36
<PAGE>   40


into, consolidate, amalgamate, or be replaced by a trust organized as such under
the laws of any state of the United States; provided, that:



     - the successor entity expressly assumes all of the obligations of that
       Apache Trust under any agreement to which the trust is a party and
       either:


        - expressly assumes all of the obligations of that Apache Trust with
          respect to the trust securities of that Apache Trust, or


        - substitutes for the trust securities of that Apache Trust other
          securities having substantially the same terms as those trust
          securities, so long as the successor trust securities rank the same as
          the trust securities rank with respect to distributions and payments
          upon liquidation, redemption and otherwise;



     - the successor entity has a trustee possessing substantially the same
       powers and duties as the property trustee;



     - the successor securities are listed, or any successor securities will be
       listed upon notification of issuance, if applicable, on each national
       securities exchange or other organization on which the trust securities
       of that Apache Trust are then listed, if any;



     - the merger, conversion, consolidation, amalgamation or replacement does
       not cause the trust securities, including any successor securities, of
       that Apache Trust to be downgraded or placed under surveillance or review
       by any nationally recognized statistical rating organization;



     - the merger, conversion, consolidation, amalgamation or replacement does
       not adversely affect the rights, preferences and privileges of the
       holders of the trust securities, including any successor securities, of
       that Apache Trust in any material respect;


     - the successor entity has a purpose substantially identical to that of
       that Apache Trust;


     - prior to the merger, conversion, consolidation, amalgamation or
       replacement, Apache has received an opinion from nationally recognized
       independent counsel to that Apache Trust experienced in these matters to
       the effect that



        - the merger, conversion, consolidation, amalgamation or replacement
          does not adversely affect the rights, preferences and privileges of
          the holders of the trust securities, including any successor
          securities, of that Apache Trust in any material respect,



        - following the merger, conversion, consolidation, amalgamation or
          replacement, neither that Apache Trust nor the successor entity, if
          any, will be required to register as an investment company under the
          Investment Company Act of 1940, as amended, and



        - following the merger, conversion, consolidation, amalgamation or
          replacement, that Apache Trust or the successor entity, as the case
          may be, will continue to be classified as a grantor trust for United
          States federal income tax purposes;


     - Apache or any permitted successor or assignee directly or indirectly owns
       all of the common securities of the successor entity and guarantees the
       obligations of the successor entity under the successor securities at
       least to the extent provided by the applicable guarantee; and

     - the property trustee has received our officer's certificate and an
       opinion of counsel, each to the effect that all conditions precedent to
       the transaction as set forth in the trust agreement have been satisfied.

                                       37

VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT


     Except as provided under "-- Mergers, Conversions, Consolidations,
Amalgamations or Replacements of an Apache Trust" and "Description of Trust
Preferred Securities Guarantees -- Amendments and Assignment" and as otherwise
required by law and the trust agreement or specified in the applicable
prospectus supplement, the holders of trust preferred securities will have no
voting rights.


     Apache, the property trustee, the Delaware trustee and the administrative
trustees may amend from time to time the trust agreement for an Apache Trust,
without the consent of the holders of the trust securities of that Apache Trust,


     - to cure any ambiguity, or correct or supplement any provisions in the
       trust agreement that may be defective or inconsistent with any other
       provision,



     - to add to the covenants, restrictions or obligations of the sponsor,



     - to conform to any change in the Investment Company Act or Trust Indenture
       Act or the rules promulgated thereunder, or any written change in
       interpretation of such acts or rules by any governmental authority, or



     - to cause that Apache Trust to continue to be classified for United States
       federal income tax purposes as a grantor trust;



provided, however, that in the case of the first bullet point above, the
modification will not adversely affect in any material respect the interests of
the holders of the trust securities issued by that Apache Trust.


     Without the consent of each holder of trust securities issued by an Apache
Trust, the trust agreement for that Apache Trust may not be amended to:

     - change the distribution rate, or manner of calculation of the
       distribution rate, amount, timing or currency or otherwise adversely
       affect the method of any required payment;

     - change its purpose;

     - authorize the issuance of any additional beneficial interests;

     - change the conversion, exchange or redemption provisions, if any;

     - change the conditions precedent for Apache to elect to dissolve that
       Apache Trust and distribute the debt securities held by that Apache Trust
       to the holders of the trust securities, if applicable;

     - change the liquidation, distribution or other provisions relating to the
       distribution of amounts payable upon the dissolution and liquidation of
       that Apache Trust;

     - affect the limited liability of any holder of its trust securities; or


     - restrict the right of a holder of its trust securities to institute suit
       for the enforcement of any required distribution on or, if applicable,
       after the due date therefor or for the conversion or exchange of the
       trust securities in accordance with their terms.


     So long as the property trustee holds any debt securities for an Apache
Trust, the property trustee, the Delaware trustee and the administrative
trustees for that Apache Trust will not:


     - direct the time, method and place of conducting any proceeding for any
       remedy available to the debt securities trustee, or execute any trust or
       power conferred on the property trustee, with respect to those debt
       securities;


     - waive certain past defaults under the applicable indenture;

     - exercise any right to rescind or annul a declaration of acceleration of
       the maturity of the principal of those debt securities; or

     - consent to any amendment, modification or termination of the applicable
       indenture or those debt securities, where consent is required.
                                       38
<PAGE>   42

without, in each case, obtaining the prior approval of the holders of a majority
in liquidation amount of all outstanding trust preferred securities of that
Apache Trust; provided, however, that where a consent under the applicable
indenture would require the consent of each holder of those debt securities
affected thereby, the property trustee will not consent without the prior
approval of each holder of the trust preferred securities issued by that Apache
Trust. The property trustee, the Delaware trustee and the administrative
trustees may not revoke any action previously authorized or approved by a vote
of the holders of trust preferred securities except by subsequent vote of the
holders. The property trustee will notify each holder of trust preferred
securities of any notice of default with respect to the applicable debt
securities. In addition to obtaining approvals of holders of trust preferred
securities referred to above, prior to taking any of the foregoing actions, the
property trustee, the Delaware trustee and the administrative trustees will
obtain an opinion of counsel experienced in these matters to the effect that the
applicable Apache Trust will not be classified as other than a grantor trust for
United States federal income tax purposes on account of such action.

     Any required approval of holders of trust preferred securities may be given
at a meeting of the holders convened for this purpose or by written consent
without prior notice. The property trustee will cause a notice of any meeting at
which holders of trust preferred securities are entitled to vote to be given to
each holder of record of trust preferred securities in the manner set forth in
the trust agreement.

     Notwithstanding that holders of trust preferred securities are entitled to
vote or consent under any of the circumstances referred to above, any trust
preferred securities that are owned by Apache or any affiliate of Apache will,
for purposes of this vote or consent, be treated as if they were not
outstanding.

GLOBAL TRUST PREFERRED SECURITIES


     Unless otherwise specified in the applicable prospectus supplement, trust
preferred securities will be represented by one or more global certificates
deposited with, or on behalf of, DTC, or other depository identified in the
prospectus supplement, or a nominee of DTC or other depository, in each case for
credit to an account of a participant in DTC or other depository. The identity
of the depository and the specific terms of the depositary arrangements with
respect to the trust preferred securities to be represented by one or more
global certificates to the extent not discussed under "Book-Entry Securities"
will be described in the applicable prospectus supplement. However, unless
otherwise specified in the applicable prospectus supplement, DTC will be the
depositary and the depository arrangements described with respect to the debt
securities will apply to those trust preferred securities as well, except all
references to Apache shall include Apache Trust I and Apache Trust II and all
references to the indentures will refer to the applicable trust agreement. See
"Description of Debt Securities -- Global Securities" and "Book-Entry
Securities."


PAYMENT AND PAYING AGENT


     Payments in respect of any global certificate representing trust preferred
securities will be made to Cede & Co. as nominee of DTC or other applicable
depository or its nominee, which will credit the relevant accounts at DTC or
other depository on the applicable payment dates, while payments in respect of
trust preferred securities in certificated form will be made by check mailed to
the address of the holder entitled thereto as the address will appear on the
register. The paying agent will initially be the property trustee and any
co-paying agent chosen by the property trustee and acceptable to the
administrative trustees and Apache. The paying agent will be permitted to resign
as paying agent upon 30 days prior written notice to the property trustee, the
administrative trustees and Apache. In the event that the property trustee will
no longer be the paying agent, the administrative trustees will appoint a
successor, which will be a bank or trust company acceptable to the
administrative trustees and Apache, to act as paying agent.

                                       39
<PAGE>   43

REGISTRAR AND TRANSFER AGENT

     The property trustee will act as registrar and transfer agent for the trust
preferred securities.


     Registration of transfers of trust preferred securities will be effected
without charge by or on behalf of an Apache Trust, upon payment of any tax or
other governmental charges that may be imposed in connection with any transfer
or exchange. An Apache Trust will not be required to register or cause to be
registered the transfer of its trust preferred securities after they have been
converted, exchanged, redeemed, repaid or called for redemption or repayment.


INFORMATION CONCERNING THE PROPERTY TRUSTEE


     The property trustee, other than during the occurrence and continuance of
an event of default under the trust agreement, will undertake to perform only
the duties that are specifically set forth in the trust agreement and, during
the continuance of that event of default, must exercise the same degree of care
and skill as a prudent person would exercise or use in the conduct of his or her
own affairs. Subject to the foregoing, the property trustee will not be under
any obligation to exercise any of the powers vested in it by the trust agreement
at the request of any holder of the related trust securities unless the holder
offers the property trustee reasonable indemnity against the costs, expenses and
liabilities that it might incur thereby.


MISCELLANEOUS


     The administrative trustees are authorized and directed to conduct the
affairs of and to operate each Apache Trust in such a way that:



     - that Apache Trust will not be deemed to be an investment company required
       to be registered under the Investment Company Act;



     - that Apache Trust will be classified as a grantor trust for United States
       federal income tax purposes; and


     - the debt securities held by that Apache Trust will be treated as
       indebtedness of Apache for United States federal income tax purposes.

Apache and the administrative trustees are authorized to take any action, not
inconsistent with applicable law, the certificate of trust of each Apache Trust
or each trust agreement, that the administrative trustees determine in their
discretion to be necessary or desirable for those purposes, as long as that
action does not materially adversely affect the interests of the holders of the
related trust securities.

     Holders of trust preferred securities will not have any preemptive or
similar rights.


              DESCRIPTION OF TRUST PREFERRED SECURITIES GUARANTEES



     Apache will execute and deliver a guarantee concurrently with the issuance
by an Apache Trust of its trust preferred securities for the benefit of the
holders from time to time of those trust preferred securities. That guarantee
will be held for those holders by a guarantee trustee. Apache will qualify each
of the guarantees as an indenture under the Trust Indenture Act. The guarantees
will be subject to, and governed by, the Trust Indenture Act. This summary of
certain terms and provisions of a guarantee does not purport to be complete and
is subject to, and qualified in its entirety by reference to, all of the
provisions of each guarantee, including the definitions of terms, and those made
a part of each guarantee by the Trust Indenture Act. A form of guarantee is
filed as an exhibit to the registration statement that includes this prospectus.
If


                                       40
<PAGE>   44

indicated in the applicable prospectus supplement, the terms of a particular
guarantee may differ from the terms discussed below.

GENERAL

     Apache will irrevocably agree to pay in full, to the extent set forth
herein, the guarantee payments to the holders of the related trust preferred
securities, as and when due, regardless of any defense, right of set-off or
counterclaim that an Apache Trust may have or assert. The following payments
constitute guarantee payments with respect to trust preferred securities and, to
the extent not paid by or on behalf of an Apache Trust, will be subject to the
applicable guarantee:

     - any accrued and unpaid distributions required to be paid on the
       applicable trust preferred securities, to the extent that an Apache Trust
       has funds legally available therefor at such time;


     - the applicable redemption or repayment price and all accrued and unpaid
       distributions to the date of redemption or repayment with respect to the
       applicable trust preferred securities called for redemption or repayment,
       to the extent that an Apache Trust has funds legally available therefor
       at such time; or



     - upon a voluntary or involuntary dissolution and liquidation of the
       applicable Apache Trust, other than in connection with the distribution
       of the debt securities to holders of its trust preferred securities or
       the redemption, repayment, conversion or exchange of its trust preferred
       securities, if applicable, the lesser of


          - the amounts due upon the dissolution and liquidation of that Apache
            Trust, to the extent that it has funds legally available therefor at
            the time, and

          - the amount of assets of that Apache Trust remaining available for
            distribution to holders of its trust preferred securities after
            satisfaction of liabilities to its creditors as required by
            applicable law.

     Apache's obligation to make a guarantee payment may be satisfied by direct
payment of the required amounts by Apache to the holders of the applicable trust
preferred securities entitled to those payments or by causing the applicable
Apache Trust to pay those amounts to the holders.

     If the trust preferred securities are exchangeable or convertible into
other securities, Apache will also irrevocably agree to cause the applicable
Apache Trust to deliver to holders of those trust preferred securities those
other securities in accordance with the applicable exchange or conversion
provisions.

     Apache will, through the guarantee, the applicable trust agreement, the
related debt securities and the applicable indenture, taken together, fully,
irrevocably and unconditionally guarantee all of each Apache Trust's obligations
under its trust preferred securities. No single document standing alone or
operating in conjunction with fewer than all of the other documents constitutes
a guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of each
Apache Trust's obligations under its trust preferred securities.

RANKING


     Unless otherwise specified in the applicable prospectus supplement, each
guarantee will constitute an unsecured obligation of Apache and will rank equal
to the debt securities held by the Apache Trust that issued the preferred trust
securities covered by the guarantee. Each trust agreement provides that each
holder of trust preferred securities, by acceptance of the applicable trust
preferred securities, agrees to the terms of the related guarantee, including
any subordination provisions.

                                       41
<PAGE>   45

     The guarantees will not limit the amount of secured or unsecured debt,
including indebtedness under the indentures, that may be incurred by Apache or
any of its subsidiaries.

GUARANTEE OF PAYMENT


     Each guarantee will constitute a guarantee of payment and not of
collection. This means that the guaranteed party may institute a legal
proceeding directly against Apache to enforce its rights under a guarantee
without first instituting a legal proceeding against any other person or entity.
A guarantee will not be discharged except by payment of the related guarantee
payments in full to the extent not paid by the applicable Apache Trust or upon
distribution of the debt securities or other assets held by the Apache Trust to
the holders of the its trust preferred securities.


AMENDMENTS AND ASSIGNMENT

     Except with respect to any changes that do not materially adversely affect
the rights of holders of the related trust preferred securities, in which case
no approval will be required, a guarantee may not be amended without the prior
approval of the holders of a majority of the liquidation amount of the
outstanding trust preferred securities covered by that guarantee. The manner of
obtaining any approval will be as set forth under "Description Of Trust
Preferred Securities -- Voting Rights; Amendment of a Trust Agreement." All
guarantees and agreements contained in a guarantee will bind the successors,
assigns, receivers, trustees and representatives of Apache and will inure to the
benefit of the holders of the related trust preferred securities then
outstanding.

EVENTS OF DEFAULT


     An event of default under a guarantee will occur upon the failure of Apache
to perform any of its payment or other obligations under that guarantee,
provided that, except with respect to a default in respect of any guarantee
payment or delivery of any securities upon conversion or exchange of the trust
securities, Apache has not cured the default 90 days from the date the guarantee
trustee obtains knowledge of the event of default. The holders of a majority in
liquidation amount of the trust preferred securities covered by a guarantee will
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 that guarantee
or to direct the exercise of any trust or power conferred upon the guarantee
trustee under that guarantee.


     If the guarantee trustee fails to enforce a guarantee, any holder of the
related trust preferred securities may institute a legal proceeding directly
against Apache to enforce its rights under that guarantee without first
instituting a legal proceeding against the applicable Apache Trust, the
guarantee trustee or any other person or entity.

TERMINATION


     A guarantee will terminate and be of no further force and effect upon full
payment of the applicable redemption or repayment price of the related trust
preferred securities, upon full payment of all amounts or delivery of all
securities or other property due upon the dissolution and liquidation of the
applicable Apache Trust or upon the conversion or exchange of all of the related
trust preferred securities. A guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of the related trust
preferred securities must restore payment of any sums paid or other property
distributed under those trust preferred securities or the related guarantee.


GOVERNING LAW

     The guarantees will be governed by and construed in accordance with the
laws of the State of New York.
                                       42
<PAGE>   46

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

     The guarantee trustee, other than during the occurrence and continuance of
a default by Apache in performance of a guarantee, will undertake to perform
only the duties that are specifically set forth in that guarantee and, during
the continuance of that default, must exercise the same degree of care and skill
as a prudent person would exercise or use in the conduct of his or her own
affairs. Subject to the foregoing, the guarantee trustee will not be under any
obligation to exercise any of the powers vested in it by a guarantee at the
request of any holder of the related trust preferred securities unless it is
offered reasonable indemnity against the costs, expenses and liabilities that it
might incur.

RIGHTS UPON DISSOLUTION

     Unless the debt securities held by an Apache Trust are distributed to
holders of the related trust preferred securities, upon any voluntary or
involuntary dissolution and liquidation of that Apache Trust, after satisfaction
of the liabilities of its creditors as required by applicable law, the holders
of those trust securities will be entitled to receive, out of assets held by
that Apache Trust, the liquidation distribution in cash. Upon any voluntary or
involuntary liquidation or bankruptcy of Apache, the property trustee, as holder
of the debt securities, would be a creditor of Apache.

            DESCRIPTION OF COMMON STOCK PURCHASE CONTRACTS AND UNITS

     We may issue stock purchase contracts, representing contracts entitling or
obligating holders to purchase from Apache, and Apache to sell to the holders, a
specified number of shares of common stock at a future date or dates. The price
per share of common stock may be fixed at the time the contracts are issued or
may be determined by reference to a specific formula set forth in the contracts.
The common stock purchase contracts may be issued separately or as a part of
units, which are referred to in this prospectus as "common stock purchase
units," consisting of a common stock purchase contract and, as security for the
holder's obligations to purchase the common stock under the contracts, the
following:

     - senior debt securities or subordinated debt securities of Apache;


     - preferred stock of Apache;


     - debt obligations of third parties, including U.S. Treasury securities;


     - trust preferred securities of an Apache Trust



     - any other security described in the applicable prospectus supplement; or


     - any combination of the foregoing.

                                       43
<PAGE>   47

     The common stock purchase contracts may require Apache to make periodic
payments to the holders of the common stock purchase units or vice versa, and
such payments may be unsecured or prefunded on some basis. The common stock
purchase contracts may require holders to secure their obligations thereunder in
a specified manner, and in certain circumstances Apache may deliver newly issued
prepaid common stock purchase contracts, which are referred to as "prepaid
securities," upon release to a holder of any collateral securing such holder's
obligations under the original contract.

     The applicable prospectus supplement will describe the terms of any common
stock purchase contracts or units and, if applicable, prepaid securities. The
description in the prospectus supplement will not purport to be complete and
will be qualified in its entirety by reference to the contracts, the collateral
arrangements and depositary arrangements, if applicable, relating to such
contracts or units and, if applicable, the prepaid securities and the document
pursuant to which such prepaid securities will be issued.

                             BOOK-ENTRY SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, we will
issue to investors securities, other than our common stock, in the form of one
or more book-entry certificates registered in the name of a depository or a
nominee of a depository. Unless otherwise specified in the applicable prospectus
supplement, the depository will be The Depository Trust Company, also referred
to as DTC. We have been informed by DTC that its nominee will be Cede & Co.
Accordingly, Cede is expected to be the initial registered holder of all
securities that are issued in book-entry form.

     No person that acquires a beneficial interest in securities issued in
book-entry form will be entitled to receive a certificate representing those
securities, except as set forth in this prospectus or in the applicable
prospectus supplement. Unless and until definitive securities are issued under
the limited circumstances described below, all references to actions by holders
or beneficial owners of securities issued in book-entry form will refer to
actions taken by DTC upon instructions from its participants, and all references
to payments and notices to holders or beneficial owners will refer to payments
and notices to DTC or Cede, as the registered holder of such securities.

     DTC has informed us that it is:

     - a limited-purpose trust company organized under New York banking laws;

     - a "banking organization" within the meaning of the New York banking laws;

     - a member of the Federal Reserve System;

     - a "clearing corporation" within the meaning of the New York Uniform
       Commercial Code; and

     - a "clearing agency" registered under the Securities Exchange Act.

     DTC has also informed us that it was created to:

     - hold securities for "participants"; and

     - facilitate the computerized settlement of securities transactions among
       participants through computerized electronic book-entry changes in
       participants' accounts, thereby eliminating the need for the physical
       movement of securities certificates.

     Participants have accounts with DTC and include securities brokers and
dealers, banks, trust companies and clearing corporations. Indirect access to
the DTC system also is available to

                                       44
<PAGE>   48

indirect participants such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a participant, either
directly or indirectly.

     Persons that are not participants or indirect participants but desire to
buy, sell or otherwise transfer ownership of or interests in securities may do
so only through participants and indirect participants. Under the book-entry
system, beneficial owners may experience some delay in receiving payments, as
payments will be forwarded by our agent to Cede, as nominee for DTC. DTC will
forward these payments to its participants, which thereafter will forward them
to indirect participants or beneficial owners. Beneficial owners will not be
recognized by the applicable registrar, transfer agent, trustee or depositary as
registered holders of the securities entitled to the benefits of the
certificate, the indenture or any deposit agreement. Beneficial owners that are
not participants will be permitted to exercise their rights as an owner only
indirectly through participants and, if applicable, indirect participants.

     Under the current rules and regulations affecting DTC, DTC will be required
to make book-entry transfers of securities among participants and to receive and
transmit payments to participants. Participants and indirect participants with
which beneficial owners of securities have accounts are also required by these
rules to make book-entry transfers and receive and transmit such payments on
behalf of their respective account holders.

     Because DTC can act only on behalf of participants, who in turn act only on
behalf of other participants or indirect participants, and on behalf of certain
banks, trust companies and other persons approved by it, the ability of a
beneficial owner of securities issued in book-entry form to pledge those
securities to persons or entities that do not participate in the DTC system may
be limited due to the unavailability of physical certificates for the
securities.

     DTC has advised us that it will take any action permitted to be taken by a
registered holder of any securities under the certificate, the indenture or any
deposit agreement only at the direction of one or more participants to whose
accounts with DTC the securities are credited.

     According to DTC, the information with respect to DTC has been provided to
its participants and other members of the financial community for informational
purposes only and is not intended to serve as a representation, warranty, or
contract modification of any kind.

     Unless otherwise specified in the applicable prospectus supplement, a
book-entry security will be exchangeable for definitive securities registered in
the names of persons other than DTC or its nominee only if:

     - DTC notifies us that it is unwilling or unable to continue as depositary
       for the book-entry security or DTC ceases to be a clearing agency
       registered under the Securities Exchange Act at a time when DTC is
       required to be so registered; or

     - we execute and deliver to the applicable registrar, transfer agent,
       trustee and/or depositary an order complying with the requirements of the
       certificate, the indenture or any deposit agreement that the book-entry
       security will be so exchangeable.

     Any book-entry security that is exchangeable in accordance with the
preceding sentence will be exchangeable for securities registered in such names
as DTC directs.

     If one of the events described in the immediately preceding paragraph
occurs, DTC is generally required to notify all participants of the availability
through DTC of definitive securities. Upon surrender by DTC of the book-entry
security representing the securities and delivery of instructions for
re-registration, the registrar, transfer agent, trustee or depositary, as the
case may be, will reissue the securities as definitive securities. After
reissuance of the securities, such persons will recognize the beneficial owners
of such definitive securities as registered holders of securities.

                                       45
<PAGE>   49

     Except as described above:

     - a book-entry security may not be transferred except as a whole book-entry
       security by or among DTC, a nominee of DTC and/or a successor depository
       appointed by us; and

     - DTC may not sell, assign or otherwise transfer any beneficial interest in
       a book-entry security unless the beneficial interest is in an amount
       equal to an authorized denomination for the securities evidenced by the
       book-entry security.

     None of Apache, the Apache Trusts, the trustees, any registrar and transfer
agent or any depositary, or any agent of any of them, will have any
responsibility or liability for any aspect of DTC's or any participant's records
relating to, or for payments made on account of, beneficial interests in a
book-entry security.

                              PLAN OF DISTRIBUTION


     Apache and the Apache Trusts may sell the securities through agents,
underwriters or dealers, or directly to one or more purchasers without using
underwriters or agents.



     Apache and the Apache Trusts may designate agents who agree to use their
reasonable efforts to solicit purchases for the period of their appointment or
to sell securities on a continuing basis.



     If Apache and/or an Apache Trust use underwriters for a sale of securities,
the underwriters will acquire the securities for their own account. The
underwriters may resell the securities in one or more transactions, including
negotiated transactions, at a fixed public offering price or at varying prices
determined at the time of sale. The obligations of the underwriters to purchase
the securities will be subject to the conditions set forth in the applicable
underwriting agreement. The underwriters will be obligated to purchase all the
securities offered if any of those securities are purchased. Any initial public
offering price and any discounts or concessions allowed or re-allowed or paid to
dealers will be described in the applicable prospectus supplement and may be
changed from time to time.



     Underwriters, dealers and agents that participate in the distribution of
the securities may be underwriters as defined in the Securities Act and any
discounts or commissions they receive from Apache and/or an Apache Trust and any
profit on their resale of the securities may be treated as underwriting
discounts and commissions under the Securities Act. The applicable prospectus
supplement will identify any underwriters, dealers or agents and will describe
their compensation. Apache and the Apache Trusts may have agreements with the
underwriters, dealers and agents to indemnify them against certain civil
liabilities, including liabilities under the Securities Act. Underwriters,
dealers and agents may engage in transactions with or perform services for us or
our subsidiaries in the ordinary course of their businesses.


TRADING MARKETS AND LISTING OF SECURITIES


     Unless otherwise specified in the applicable prospectus supplement, each
class or series of securities will be a new issue with no established trading
market, other than the common stock, which is listed on the New York Stock
Exchange and the Chicago Stock Exchange. Apache and the Apache Trusts may elect
to list any other class or series of securities on any exchange but are not
obligated to do so. It is possible that one or more underwriters may make a
market in a class or series of securities, but the underwriters will not be
obligated to do so and may discontinue any market making at any time without
notice. Neither Apache nor the Apache Trusts can give any assurance as to the
liquidity of the trading market for any of the securities.


                                       46
<PAGE>   50

STABILIZATION ACTIVITIES

     Any underwriter may engage in over-allotment, stabilizing transactions,
short-covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act. Over-allotment involves sales in excess of
the offering size, which create a short position. Stabilizing transactions
permit bids to purchase the underlying security so long as the stabilizing bids
do not exceed a specified maximum. Short-covering transactions involve purchases
of the securities in the open market after the distribution is completed to
cover short positions. Penalty bids permit the underwriters to reclaim a selling
concession from a dealer when the securities originally sold by the dealer are
purchased in a covering transaction to cover short positions. Those activities
may cause the price of the securities to be higher than it would otherwise be.
If commenced, the underwriters may discontinue any of the activities at any
time.

                                 LEGAL MATTERS


     The legality of the securities issued by Apache will be passed upon for
Apache by its Vice President and General Counsel, Z. S. Kobiashvili, or its
Attorney and Assistant Secretary, Jeffrey B. King. As of the date of this
prospectus, Mr. Kobiashvili holds employee stock options to purchase 56,550
shares of Apache common stock, of which options to purchase 30,125 shares are
currently exercisable, and he holds 1,522 units in Apache's Deferred Delivery
Plan, each equivalent to one share of Apache common stock. As of the date of
this prospectus, Mr. King owns 52 shares of Apache common stock through Apache's
401(k) savings plan and holds employee stock options to purchase 3,950 shares of
Apache common stock, of which options to purchase 487 shares are currently
exercisable. In addition, other customary legal matters relating to the offering
of the securities issued by Apache, including matters relating to our due
incorporation, legal existence and authorized capitalization, will be passed
upon for Apache by Mr. Kobiashvili, Mr. King or Mayor, Day, Caldwell & Keeton,
L.L.P., Houston, Texas. The legality of the securities issued by the Apache
Trusts and certain matters of Delaware law will be passed upon for the Apache
Trusts by Richards, Layton & Finger, P.A., special Delaware counsel to the
Apache Trusts. Unless otherwise specified in the accompanying prospectus
supplement, certain legal matters will be passed upon for any underwriters or
agents by Brown & Wood LLP, New York, New York.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Apache's Certificate of Incorporation and bylaws provide that, to the full
extent permitted under the Delaware General Corporation Law, Apache's directors
shall not be personally liable for monetary damages and Apache shall indemnify
its officers, directors, employees and agents.

     Section 145 of the Delaware General Corporation Law, inter alia, authorizes
a corporation to indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, other than an action by or in the right of the corporation, because
such person is or was a director, officer, employee or agent of the corporation
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation or other enterprise, against expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had no reason to believe his conduct was
unlawful. Similar indemnity is authorized for such persons against expenses,
including attorneys' fees, actually and reasonably incurred in defense or
settlement of any such pending, completed or threatened action or suit by or in
the right of the corporation if such person acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and provided further that, unless a court of competent jurisdiction
otherwise provides, such person shall not have been adjudged liable to the
corporation. Any such indemnification may be made only as authorized in each
specific case upon a determination by the stockholders or disinterested
directors that indemnification is proper because the indemnitee has met the
applicable standard of conduct.

     Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would otherwise have the power to indemnify him. Apache maintains policies
insuring its and its subsidiaries' officers and directors against certain
liabilities for actions taken in such capacities, including liabilities under
the Securities Act of 1933.

     Article VII of Apache's bylaws provides, in substance, that directors,
officers, employees and agents of Apache shall be indemnified to the extent
permitted by Section 145 of the Delaware

                                      II-1
<PAGE>   53

General Corporation Law. Additionally, Article Seventeen of Apache's restated
certificate of incorporation eliminates in certain circumstances the monetary
liability of directors of Apache for a breach of their fiduciary duty as
directors. These provisions do not eliminate the liability of a director:

     - for a breach of the director's duty of loyalty to Apache or its
       stockholders;

     - for acts or omissions by the director not in good faith;

     - for acts or omissions by a director involving intentional misconduct or a
       knowing violation of the law;

     - under Section 174 of the Delaware General Corporation Law, which relates
       to the declaration of dividends and purchase or redemption of shares in
       violation of the Delaware General Corporation Law; and

     - for transactions from which the director derived an improper personal
       benefit.

     Reference is made to the form of underwriting agreements to be incorporated
by reference in this registration statement for a description of the
indemnification arrangements Apache and the Apache Trusts agree to in connection
with offerings of the securities registered by this registration statement.


     The Apache Trusts' trust agreements provide that no trustee, affiliate of
any trustee or any officers, directors, stockholders, members, partners,
employees, representatives or agents of any trustee or any employee or agent of
the Apache Trust or its affiliates, each referred to as an "indemnified person,"
shall be liable, responsible or accountable in damages or otherwise to the
Apache Trust or its affiliates, or any officers, directors, stockholders,
employees, representatives or agents of Apache or its affiliates or to any
holders of trust preferred securities of the Apache Trust for any loss, damage
or claim incurred by reason of any act or omission performed or omitted by the
indemnified person in good faith on behalf of such Apache Trust and in a manner
the indemnified person reasonably believed to be within the scope of the
authority conferred on it by the trust agreement or by law, except that the
indemnified person shall be liable for any loss, damage or claim incurred by
reason of that indemnified person's gross negligence (or, in the case of the
property trustee of the Apache Trust, negligence), bad faith or willful
misconduct with respect to such acts or omissions. The trust agreements also
provide that Apache shall indemnify each administrative trustee, their
affiliates, any officers, directors, shareholders, members, partners, employees,
representatives or agents of any administrative trustee or any affiliate of any
administrative trustee, or any officer, employee or agent of the Apache Trust or
its affiliates, each referred to as a "company indemnified person," who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Apache Trust),
against expenses (including reasonable attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred if such company
indemnified person acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Apache Trust, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his conduct was unlawful. Apache will also indemnify any company indemnified
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the Apache
Trust to procure a judgment in its favor against expenses (including reasonable
attorneys' fees) actually and reasonably incurred by him if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Apache Trust, except that no such indemnification shall be made
if such company indemnified person shall have been adjudged to be liable to the
Trust.


                                      II-2
<PAGE>   54


     The trust agreement further provides that expenses (including legal fees)
incurred by a company indemnified person in defending any civil, criminal,
administrative or investigative action, suit or proceeding shall, from time to
time, be advanced by Apache prior to the final disposition of such action, suit
or proceeding upon receipt by Apache of an undertaking by or on behalf of the
company indemnified person to repay such amount if it shall be determined that
the company indemnified person is not entitled to be indemnified pursuant to the
trust agreement.



     The trust agreements also provide that Apache shall indemnify the property
trustee, the Delaware trustee, any affiliate of the property trustee or the
Delaware trustee, and any officers, directors, shareholders, members, partners,
employees, representatives, custodians, nominees or agents of the property
trustee or Delaware trustee, each a "fiduciary indemnified person," for and hold
each such fiduciary indemnified person harmless against any loss, liability or
expense to the extent incurred without gross negligence (or in the case of the
property trustee, negligence), bad faith or willful misconduct on its part,
arising out of or in connection with the acceptance or administration of the
Apache Trust, including costs and expenses (including reasonable legal fees and
expenses) of defending itself against or investigating any claim or liability in
connection with the exercise or performance of any of its powers or duties under
the trust agreement.

ITEM 17. UNDERTAKINGS

     1. The undersigned Registrants hereby undertake:

          (a) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement.

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in the volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculations of
        Registration Fee" table in the effective Registration Statement; and

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change to such information in the Registration
        Statement;

           Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if
           the information required to be included in a post-effective amendment
           by those paragraphs is contained in periodic reports filed by the
           Registrant pursuant to

                                      II-5
<PAGE>   57

           Section 13 or 15(d) of the Securities Exchange Act of 1934, that are
           incorporated by reference in the Registration Statement;

          (b) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new Registration Statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof; and

          (c) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     2. The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
Apache's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934 that is incorporated by reference in the Registration Statement) shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     3. Insofar as indemnification for liabilities arising under the Securities
Act of 1933, may be permitted to directors, officers and controlling persons of
the Registrants pursuant to the provisions described under Item 15 above, or
otherwise, the Registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
any Registrant of expenses incurred or paid by a director, officer or
controlling person of that Registrant in the successful defense of any action,
suit or proceeding) is asserted against any Registrant by such director, officer
or controlling person in connection with the securities being registered, that
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

     4. The undersigned Registrants hereby undertake that:

          (a) For the purpose of determining any liability under the Securities
     Act of 1933, the information omitted from the form of prospectus filed as
     part of this Registration Statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the Registrants pursuant to Rule
     424(b)(1) or (4) or 497(h) under the Securities Act, as amended, shall be
     deemed to be part of this Registration Statement as of the time it was
     declared effective; and

          (b) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     5. The undersigned Registrants hereby undertake to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Act.

corporation duly organized and existing under the laws of the State of New York
(hereinafter called the "Trustee"), having its Corporate Trust Office located at
450 West 33rd Street, 15th Floor, New York, New York 10001.


                                    RECITALS

         The Company has duly authorized the execution and delivery of this
Indenture to provide for the issuance from time to time of its subordinated
unsecured debentures, notes or other evidence of Indebtedness (hereinafter
called the "Securities"), unlimited as to principal amount, to bear such rates
of interest, to mature at such time or times, to be issued in one or more series
and to have such other provisions as shall be fixed as hereinafter provided.

         The Company may from time to time create or establish one or more
statutory business trusts for the purpose of issuing undivided beneficial
interests in the assets thereof and using the proceeds thereof to acquire the
Company's Securities.

         The Company has duly authorized the execution and delivery of this
Indenture. All things necessary to make this Indenture a valid agreement of the
Company, in accordance with its terms, have been done.

         This Indenture is subject to the provisions of the Trust Indenture Act
of 1939, as amended, and the rules and regulations of the Securities and
Exchange Commission promulgated thereunder that are required to be part of this
Indenture and, to the extent applicable, shall be governed by such provisions.

         NOW, THEREFORE, THIS INDENTURE WITNESSETH:

         For and in consideration of the premises and the purchase of the
Securities by the Holders (as herein defined) thereof, it is mutually covenanted
and agreed, for the equal and proportionate benefit of all Holders of the
Securities or of any series thereof and any Coupons (as herein defined) as
follows:

                                   ARTICLE 1.

             DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

         Section 101. Definitions.

         Except as otherwise expressly provided in or pursuant to this Indenture
or unless the context otherwise requires, for all purposes of this Indenture:

                  (1) the terms defined in this Article have the meanings
         assigned to them in this Article, and include the plural as well as the
         singular;


<PAGE>   10

                  (2) all other terms used herein which are defined in the Trust
         Indenture Act, either directly or by reference therein, have the
         meanings assigned to them therein;

                  (3) all accounting terms not otherwise defined herein have the
         meanings assigned to them in accordance with generally accepted
         accounting principles and, except as otherwise herein expressly
         provided, the terms "generally accepted accounting principles" or
         "GAAP" with respect to any computation required or permitted hereunder
         shall mean such accounting principles as are generally accepted at the
         date of such computation;

                  (4) the words "herein", "hereof", "hereto" and "hereunder" and
         other words of similar import refer to this Indenture as a whole and
         not to any particular Article, Section or other subdivision; and

                  (5) the word "or" is always used inclusively (for example, the
         phrase "A or B" means "A or B or both", not "either A or B but not
         both").

         Certain terms used principally in certain Articles hereof are defined

         "Act", when used with respect to any Holder, has the meaning specified

indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,

whether through the ownership of voting securities, by contract or otherwise;
and the terms "controlling" and "controlled" have the meanings correlative to

         Section 103. Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by or
covered by an opinion of any specified Person, it is not necessary that all such
matters be certified by, or covered by the opinion of, only one such Person, or
that they be so certified or covered by only one document, but one such Person
may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give
an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon an Opinion of Counsel, unless such
officer knows, or in the exercise of reasonable care should know, that the
opinion with respect to the matters upon which his certificate or opinion is
based are erroneous. Any such Opinion of Counsel may be based. insofar as it
relates to factual matters, upon a certificate or opinion of, or representations
by, an officer or officers of the Company stating that information with respect
to such factual matters is in the possession of the Company unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respell to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture or any Security, they may, but need not, be
consolidated and form one instrument.

         Section 104. Acts of Holders and Holders of Preferred Securities.

                  (1) Any request, demand, authorization, direction, notice,
         consent, waiver or other action provided by or pursuant to this
         Indenture to be given or taken by Holders or by holders of Preferred
         Securities may be embodied in and evidenced by one or more instruments
         of substantially similar tenor signed by such Holders or holders of
         Preferred Securities, as applicable, in person or by an agent duly
         appointed in writing. If, but only if, Securities of a series are
         issuable as Bearer Securities, any request, demand, authorization,
         direction, notice, consent, waiver or other action provided in or
         pursuant to this Indenture to be given or taken by Holders of
         Securities of such series or by holders of Preferred Securities may,
         alternatively, be embodied in and evidenced by the record of Holders of
         Securities of such series or by holders of Preferred Securities voting
         in favor thereof, either in person or by proxies duly appointed in
         writing, at any meeting of Holders of Securities of such series duly
         called and held in accordance with the provisions of Article Fourteen,
         or a combination of such instruments and any such record. Except as
         herein otherwise expressly provided, such action shall become effective
         when such instrument or instruments or record or both are delivered to
         the Trustee and, where it is hereby expressly required, to the Company.
         Such instrument or instruments and any such record (and the action
         embodied therein and evidenced thereby) are herein sometimes referred
         to as the "Act" of the Holders or holders of Preferred Securities
         signing such instrument or instruments or so voting at any such
         meeting. Proof of execution of any such instrument or of a writing
         appointing any such agent, or of the holding by any Person of a
         Security, shall be sufficient for any purpose of this Indenture and
         (subject to Section 315 of the Trust Indenture Act) conclusive in favor
         of the Trustee



                                       12
<PAGE>   21

         and the Company and any agent of the Trustee or the Company, if made in
         the manner provided in this Section 104. The record of any meeting of
         Holders of Securities shall be proved in the manner provided in Section
         1406.

                  Without limiting the generality of this Section 104, unless
         otherwise provided in or pursuant to this Indenture, a Holder,
         including a U.S. Depository that is a Holder of a global Security, may
         make, give or take, by a proxy, or proxies, duly appointed in writing,
         any request, demand, authorization, direction, notice, consent, waiver
         or other Act provided in or pursuant to this Indenture to be made,
         given or taken by Holders, and a U.S. Depository that is a Holder of a
         global Security may provide its proxy or proxies to the beneficial
         owners of interests in any such global Security through such U.S.
         Depository's standing instructions and customary practices.

                  The Trustee shall fix a record date for the purpose of
         determining the Persons who are beneficial owners of interest in any
         permanent global Security held by a U.S. Depository entitled under the
         procedures of such U.S. Depository to make, give or take, by a proxy or
         proxies duly appointed in writing, any request, demand, authorization,
         direction, notice, consent, waiver or other Act provided in or pursuant
         to this Indenture to be made, given or taken by Holders. If such a
         record date is fixed, the Holders on such record date or their duly
         appointed proxy or proxies, and only such Persons, shall be entitled to
         make, give or take such request, demand, authorization, direction,
         notice, consent, waiver or other Act, whether or not such Holders
         remain Holders after such record date. No such request, demand,
         authorization, direction, notice, consent, waiver or other Act shall be
         valid or effective if made, given or taken more than 90 days after such
         record date.

                  (2) The fact and date of the execution by any Person of any
         such instrument or writing may be proved in any reasonable manner which
         the Trustee deems sufficient and in accordance with such reasonable
         rules as the Trustee may determine; and the Trustee may in any instance
         require further proof with respect to any of the matters referred to in
         this Section 104.

                  (3) The ownership, principal amount and serial numbers of
         Registered Securities held by any Person, and the date of the
         commencement and the date of the termination of holding the same, shall
         be proved by the Security Register.

                  (4) The ownership, principal amount and serial numbers of
         Bearer Securities held by any Person, and the date of the commencement
         and the date of the termination of holding the same, may be proved by
         the production of such Bearer Securities or by a certificate executed,
         as depositary, by any trust company, bank, banker or other depositary
         reasonably acceptable to the Company, wherever situated, if such
         certificate shall be deemed by the Company and the Trustee to be
         satisfactory, showing that at the date therein mentioned such Person
         had on deposit with such depositary, or exhibited to it, the Bearer
         Securities therein described; or such facts may be proved by the
         certificate or affidavit of the Person holding such Bearer Securities,
         if such certificate or affidavit is deemed by the Trustee to be
         satisfactory. The Trustee and the Company may assume that such
         ownership of any Bearer Security continues until (1) another
         certificate or affidavit



                                       13
<PAGE>   22

         bearing a later date issued in respect of the same Bearer Security is
         produced, or (2) such Bearer Security is produced to the Trustee by
         some other Person, or (3) such Bearer Security is surrendered in
         exchange for a Registered Security, or (4) such Bearer Security is no
         longer Outstanding. The ownership, principal amount and serial numbers
         of Bearer Securities held by the Person so executing such instrument or
         writing and the date of the commencement and the date of the
         termination of holding the same may also be proved in any other manner
         which the Company and the Trustee deem sufficient.

                  (5) If the Company shall solicit from the Holders of any
         Registered Securities any request, demand, authorization, direction,
         notice, consent, waiver or other Act, the Company may at its option
         (but is not obligated to), by Board Resolution, fix in advance a record
         date for the determination of Holders of Registered Securities entitled
         to give such request, demand, authorization, direction, notice,
         consent, waiver or other Act. If such a record date is fixed, such
         request, demand, authorization, direction, notice, consent, waiver or
         other Act may be given before or after such record date, but only the
         Holders of Registered Securities of record at the close of business on
         such record date shall be deemed to be Holders for the purpose of
         determining whether Holders of the requisite proportion of Outstanding
         Securities have authorized or agreed or consented to such request,
         demand, authorization, direction, notice, consent, waiver or other Act,
         and for that purpose the Outstanding Securities shall be computed as of
         such record date; provided that no such authorization, agreement or
         consent by the Holders of Registered Securities 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.

                  (6) Any request, demand, authorization, direction, notice,
         consent, waiver or other Act by the Holder of any Security shall bind
         every future Holder of the same Security and the Holder of every
         Security issued upon the registration of transfer thereof or in
         exchange therefor or in lieu thereof in respect of anything done or
         suffered to be done by the Trustee, any Security Registrar, any Paying
         Agent, any Conversion Agent or the Company in reliance thereon, whether
         or not notation of such Act is made upon such Security.

         Section 105. Notices, etc. to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of Holders or holders of Preferred Securities or other document
provided or permitted by this Indenture to be made upon, given or furnished to,
or filed with,

                  (1) the Trustee by any Holder or holder of a Preferred
         Security or the Company shall be sufficient for every purpose hereunder
         if made, given, furnished or filed in writing to or with the Trustee at
         its Corporate Trust Office, Attention: Corporate Market Fiduciary
         Services, or

                  (2) the Company by the Trustee or any Holder or holder of a
         Preferred Security shall be sufficient for every purpose hereunder
         (unless otherwise herein expressly provided) if in writing and mailed,
         first-class postage prepaid, to the Company addressed to the attention
         of its Treasurer at the address of its principal office specified in



                                       14
<PAGE>   23

         the first paragraph of this instrument or at any other address
         previously furnished in writing to the Trustee by the Company.

         Section 106. Notice to Holders of Securities; Waiver.

         Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

                  (1) such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at his address as it appears in the Security Register, not later
         than the latest date, and not earlier than the earliest date,
         prescribed for the giving of such notice; and

                  (2) such notice shall be sufficiently given to Holders of
         Bearer Securities, if any, if published in an Authorized Newspaper in
         The City of New York and, if such Securities are then listed on any
         stock exchange outside the United States, in an Authorized Newspaper in
         such city as the Company shall advise the Trustee that such stock
         exchange so requires, on a Business Day at least twice, the first such
         publication to be not earlier than the earliest date and the second
         such publication not later than the latest date prescribed for the
         giving of such notice.

         In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

         In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         Section 107. Language of Notices.

         Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted under this Indenture shall be in the
English language, except that, if the Company so elects, any published notice
may be in an official language of the country of publication.

         Section 108. Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

         Section 109. Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         Section 110. Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         Section 111. Separability Clause.

         In case any provision in this Indenture, any Security or any Coupon
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         Section 112. Benefits of Indenture.

         Except as otherwise expressly provided herein with respect to holders
of Senior Indebtedness and holders of Preferred Securities, nothing in this
Indenture, any Security or any Coupon, express or implied, shall give to any
Person, other than the parties hereto, any Security Registrar, any Paying Agent,
any Conversion Agent and their successors hereunder and the Holders of
Securities or Coupons, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

         Section 113. Governing Law.

         This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to

         Section 114. Legal Holidays.

Securities, in any case where any Interest Payment Date, Business Day following
any Change in Control Purchase Date or Stated Maturity or Maturity of any
Security shall be a Legal Holiday at any Place of Payment, then (notwithstanding
any other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and no interest shall accrue on the amount payable on such date or at
such time for the period from and after such Interest Payment Date, Business Day
following any Change in Control Purchase Date, Stated Maturity or Maturity, as
the case may be, to the next succeeding Business Day.

         Section 116. Judgment Currency.

         The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the Required Currency with the Judgment Currency on the
New York Banking Day preceding that on which a final unappealable judgment is
given and (b) the Company's obligations under this Indenture to make payments in
the Required Currency (i) shall not be discharged or satisfied by any tender, or
any recovery pursuant to any judgment (whether or not entered in accordance with
clause (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture. For purposes of the foregoing, "New York Banking Day" means any
day except a Saturday, Sunday or a legal holiday in The City of New York or a
day on which banking institutions in The City of New York are authorized or
obligated by law, regulation or executive order to be closed.

delivered, any instructions by the Company with respect to a Security in global
form shall be in writing but need not be accompanied by or contained in an
Officers' Certificate and need not be accompanied by an Opinion of Counsel.

         Notwithstanding the provisions of Section 307, unless otherwise

                                   ARTICLE 3.

                                 THE SECURITIES

         to Section 304, 305, 306, 905 or 1107, upon repayment on part of any

         any deletions from or modifications of or additions to the terms of
         this Indenture to provide for or to facilitate the issuance of
         Securities denominated or payable, at the election of the Company or a
         Holder thereof or otherwise, in a Foreign Currency;

                  (19) whether the amount of payments of principal of, any

                  (20) any deletions from, modifications of or additions to the
         Events of Default or covenants of the Company with respect to any of
         such Securities, whether or not such Events of Default or covenants are
         consistent with the Events of Default or covenants set forth herein;

                  (21) if either or both of Section 402(2) relating to
         defeasance or Section 402(3) relating to covenant defeasance shall be
         applicable to the Securities of such series, or any covenants in

         certain certificates or other documents or satisfaction of other
         conditions, then the form and terms of such certificates, documents or
         conditions;

                  (24) if there is more than one Trustee, the identity of the

         respect to such Securities;

                  (26) the name of the applicable Trust (which shall distinguish
         such statutory business trust from all other Trusts), if any, to which
         the Securities of such series are to be deposited as assets and the
         date of its Trust Agreement; and

                  (27) any other terms of such Securities and any deletions from
         or modifications or additions to this Indenture in respect of such
         Securities.

         All Securities of any one series and all Coupons, if any, appertaining
to Bearer Securities of such series shall be substantially identical except as
to Currency of payments due thereunder, denomination and the rate of interest,
or method of determining the rate of interest, if any, Maturity, and the date
from which interest, if any, shall accrue and except as may otherwise be
provided by the Company in or pursuant to the Board Resolution and set forth in
the Officers' Certificate or in any indenture or indentures supplemental hereto
pertaining to such series of Securities. The terms of the Securities of any
series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon telephonic or written order of persons designated in the Officers'
Certificate or supplemental indenture (telephonic instructions to be promptly
confirmed in writing by such person) and that such persons are authorized to
determine, consistent with such Officers' Certificate or any applicable
supplemental indenture, such terms and conditions of the Securities of such
series as are specified in such Officers' Certificate or supplemental indenture.
All Securities of any one series need not be issued at the same time and, unless
otherwise so provided by the Company, a series may be reopened for issuances of
additional Securities of such series or to establish additional terms of such
series of Securities.

         If any of the terms of the Securities of any series shall be
established by action taken by or pursuant to a Board Resolution, the Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of such series.

         Section 302. Currency; Denominations.

         Unless otherwise provided in or pursuant to this Indenture, the
principal of, any premium and interest on and any Additional Amounts with
respect to the Securities shall be payable in Dollars. Unless otherwise provided
in or pursuant to this Indenture, Registered Securities denominated in Dollars
shall be issuable in registered form without Coupons in denominations of $1,000
and any integral multiple thereof, and the Bearer Securities denominated in
Dollars shall be issuable in the denomination of $5,000. Securities not
denominated in Dollars shall be issuable in such denominations as are
established with respect to such Securities in or pursuant to this Indenture.

         Section 303. Execution, Authentication, Delivery and Dating.

         Securities shall be executed on behalf of the Company by its Chairman
of the Board, one of its Vice Chairmen, its President, its Treasurer, one of its
Assistant Treasurers or one of its Vice Presidents under its corporate seal
reproduced thereon and attested by its Secretary or one of its Assistant
Secretaries. Coupons shall be executed on behalf of the Company by the
Treasurer, one of its Vice Presidents or any Assistant Treasurer of the Company.
The signature



                                       23
<PAGE>   32

of any of these officers on the Securities or any Coupons appertaining thereto
may be manual or facsimile.

         Securities and any Coupons appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such
Securities or Coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officers' Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 301 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

         (1) an Opinion of Counsel to the effect that:

                  (a) the form or forms and terms of such Securities and
         Coupons, if any, have been established in conformity with the
         provisions of this Indenture;

                  (b) all conditions precedent to the authentication and
         delivery of such Securities and Coupons, if any, appertaining thereto,
         have been complied with and that such Securities, and Coupons, when
         completed by appropriate insertions, executed under the Company's
         corporate seal and attested by duly authorized officers of the Company,
         delivered by duly authorized officers of the Company to the Trustee for
         authentication pursuant to this Indenture, and authenticated and
         delivered by the Trustee and issued by the Company in the manner and
         subject to any conditions specified in such Opinion of Counsel, will
         constitute legally valid and binding obligations of the Company,
         enforceable against the Company in accordance with their terms, except
         as enforcement thereof may be subject to or limited by bankruptcy,
         insolvency, reorganization, moratorium, arrangement, fraudulent
         conveyance, fraudulent transfer or other similar laws relating to or
         affecting creditors' rights generally, and subject to general
         principles of equity (regardless of whether enforcement is sought in a
         proceeding in equity or at law) and will entitle the Holders thereof to
         the benefits of this Indenture; such Opinion of Counsel need express no
         opinion as to the availability of equitable remedies;

                  (c) all laws and requirements in respect of the execution and
         delivery by the Company of such Securities and Coupons, if any, have
         been complied with; and

                  (d) this Indenture has been qualified under the Trust
         Indenture Act; and



                                       24
<PAGE>   33

                  (2) an Officers' Certificate stating that, to the best
         knowledge of the Persons executing such certificate, no event which is,
         or after notice or lapse of time or both would become, an Event of
         Default with respect to any of the Securities shall have occurred and
         be continuing.

         If all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel and an Officers'
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate
Securities of such series for original issue will be deemed to be a
certification by the Company that all conditions precedent provided for in this
Indenture relating to authentication and delivery of such Securities continue to
have been complied with.

         The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

         Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

         No Security or Coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose, unless
there appears on such Security a certificate of authentication substantially in
the form provided for in Section 202 or 611 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 306 or 307, the Trustee
shall not authenticate and deliver any Bearer Security unless all Coupons
appertaining thereto then matured have been detached and cancelled.

         Section 304. Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in of pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

         Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall



                                       25
<PAGE>   34

cause definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities of the same series and containing terms and
provisions that are identical to those of any temporary Securities, such
temporary Securities shall be exchangeable for such definitive Securities upon
surrender of such temporary Securities at an Office or Agency for such
Securities, without charge to any Holder thereof. Upon surrender for
cancellation of any one or more temporary Securities (accompanied by any
unmatured Coupons appertaining thereto), the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

         Section 305. Registration, Transfer and Exchange.

         With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

         Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall




                                       26
<PAGE>   35

authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

         If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, with all unmatured
Coupons and all matured Coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured Coupon or Coupons
or matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

         If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

         Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a



                                       27
<PAGE>   36

successor depository is not appointed by the Company within 90 days of the date
the Company is so informed in writing, (ii) the Company executes and delivers to
the Trustee a Company Order to the effect that such global Security shall be so
exchangeable, or (iii) an Event of Default has occurred and is continuing with
respect to the Securities. If the beneficial owners of interests in a global
Security are entitled to exchange such interests for definitive Securities as
the result of an event described in clause (i), (ii) or (iii) of the preceding
sentence, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities in such form and denominations as
are required by or pursuant to this Indenture, and of the same series,
containing identical terms and in aggregate principal amount equal to the
principal amount of such global Security, executed by the Company. On or after
the earliest date on which such interests may be so exchanged, such global
Security shall be surrendered from time to time by the U.S. Depository or such
other Depository as shall be specified in the Company Order with respect
thereto, and in accordance with instructions given to the Trustee and the U.S.
Depository or such other Depository, as the case may be (which instructions
shall be in writing but need not be contained in or accompanied by an Officers'
Certificate or be accompanied by an Opinion of Counsel), as shall be specified
in the Company Order with respect thereto to the Trustee, as the Company's agent
for such purpose, to be exchanged, in whole or in part, for definitive
Securities as described above without charge. The Trustee shall authenticate and
make available for delivery, in exchange for each portion of such surrendered
global Security, a like aggregate principal amount of definitive Securities of
the same series of authorized denominations and of like tenor as the portion of
such global Security to be exchanged, which (unless such Securities are not
issuable both as Bearer Securities and as Registered Securities, in which case
the definitive Securities exchanged for the global Security shall be issuable
only in the form in which the Securities are issuable, as provided in or
pursuant to this Indenture) shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof, but subject to the satisfaction of any certification
or other requirements to the issuance of Bearer Securities; provided, however,
that no such exchanges may occur during a period beginning at the opening of
business 15 days before any selection of Securities of the same series to be
redeemed and ending on the relevant Redemption Date; and provided, further, that
(unless otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depository or the U.S. Depository, as the case may be, or such other
Depository or U.S. Depository referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next Interest Payment Date, or (ii) any
Special Record Date for such Security and before the opening of business at such
Office or Agency on the related proposed date for payment of interest or
Defaulted Interest, as the case may be, interest shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security, but shall be payable on such Interest
Payment Date or proposed date for payment, as the case may be, only to the
Person to whom interest in respect of such portion of such global Security shall
be payable in accordance with the provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company evidencing the same
debt and entitling the Holders thereof to the same benefits under this Indenture
as the Securities surrendered upon such registration of transfer or exchange.

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

         No service charge shall be made for any registration of transfer or
exchange, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge.

         Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of the selection for redemption of Securities of like tenor and
the same series under Section 1103 and ending at the close of business on the
day of such selection, or (ii) to register the transfer of or exchange any
Registered Security so selected for redemption in whole or in part, except in
the case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

         Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons. if any, appertaining to the surrendered Security.

         If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon has been acquired by a
protected purchaser. the Company shall execute and, upon Company Request the
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Security or in exchange for the Security to
which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons
not destroyed, lost or stolen, a new



                                       29
<PAGE>   38

Security of the same series containing identical terms and of like principal
amount and bearing a number not contemporaneously outstanding, with Coupons
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

         Notwithstanding the foregoing provisions of this Section 306, in case
any mutilated, destroyed, lost or stolen Security or Coupon has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Security, pay such Security or Coupon; provided, however, that
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 1002, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on Bearer Securities and any Additional Amounts with respect to
such interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.

         Upon the issuance of any new Security under this Section 306, 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.

         Every new Security, with any Coupons appertaining thereto issued
pursuant to this Section 306 in lieu of any destroyed, lost or stolen Security,
or in exchange for a Security to which a destroyed, lost or stolen Coupon
appertains shall constitute a separate obligation of the Company, whether or not
the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and the
Coupons, if any, duly issued hereunder.

         The provisions of this Section 306, as amended or supplemented pursuant
to this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

         Section 307. Payment of Interest and Certain Additional Amounts; Rights
                      to Interest and Certain Additional Amounts Preserved.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, and are punctually paid or duty provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered as of the close of
business on the Regular Record Date for such interest. Unless otherwise provided
in or pursuant to this Indenture, in case a Bearer Security is surrendered in
exchange for a Registered Security after the close of business at an Office or
Agency for such Security on any Regular Record Date therefor and before the
opening of business at such Office or Agency on the next succeeding Interest
Payment Date therefor, such Bearer Security shall be surrendered without the
Coupon relating to such Interest Payment Date and interest shall not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but shall



                                       30
<PAGE>   39

be payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, but shall not be punctually paid or duly provided for,
on any Interest Payment Date for such Registered Security (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder thereof
on the relevant Regular Record Date by virtue of having been such Holder; and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Person in whose name such Registered Security (or a
         Predecessor Security thereof) shall be 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 such Registered Security 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 on or prior
         to the date of the proposed payment, such money when so deposited to be
         held in trust for the benefit of the Person 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 be not more than 15 days and not 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 the
         Holder of such Registered Security (or a Predecessor Security thereof)
         at his address as it appears in the Security Register not less than 10
         days prior to such Special Record Date. The Trustee may, in its
         discretion, in the name and at the expense of the Company cause a
         similar notice to be published at least once in an Authorized Newspaper
         of general circulation in the Borough of Manhattan, The City of New
         York, but such publication shall not be a condition precedent to the
         establishment of 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 Person in whose name such Registered Security (or a Predecessor
         Security thereof) shall be registered at the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following clause (2). In case a Bearer Security is surrendered at the
         Office or Agency for such Security in exchange for a Registered
         Security after the close of business at such Office or Agency on any
         Special Record Date and before the opening of business at such Office
         or Agency on the related proposed date for payment of Defaulted
         Interest, such Bearer Security shall be surrendered without the Coupon
         relating to such Defaulted Interest and Defaulted Interest shall not be
         payable on such proposed date of payment in respect of the Registered
         Security issued in exchange for such Bearer Security, but shall be
         payable



                                       31
<PAGE>   40

         only to the Holder of such Coupon when due in accordance with the
         provisions of this Indenture.

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

         Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series, at the option of the Company, interest on
Registered Securities that bear interest may be paid by mailing a check to the
address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States.

         Subject to the foregoing provisions of this Section 307 and Section
305, each Security delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         If any convertible or exchangeable Security of any series is converted
or exchanged after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Security with respect to which
the Stated Maturity Date is prior to such Interest Payment Date), interest that
is due on such Interest Payment Date shall be payable on such Interest Payment
Date notwithstanding such conversion or exchange, and such interest (whether or
not punctually paid or duly provided for ) shall be paid to the Person in whose
name that Security is registered at the close of business on such Regular Record
Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security that is converted or exchanged, interest
shall not be payable if the Regular Record Date is after the date of conversion
or exchange of such Security.

         Section 308. Persons Deemed Owners.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 305 and
307) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall



                                       32
<PAGE>   41

be overdue, and neither the Company, nor the Trustee or any agent of the Company
or the Trustee shall be affected by notice to the contrary.

         No holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent, any Conversion Agent or the Security Registrar will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

         Section 309. Cancellation.

         All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. The Company may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be cancelled promptly by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section 309, except as expressly
permitted by or pursuant to this Indenture. All cancelled Securities and Coupons
held by the Trustee shall be destroyed by the Trustee, unless by a Company Order
the Company directs their return to it.

         Section 310. Computation of Interest.

         Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

                                   ARTICLE 4.

         Section 401. Satisfaction and Discharge.

Trustee, on receipt of a Company Order, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when:

         and delivered and all Coupons appertaining thereto (other than (i)
         Coupons appertaining to Bearer Securities of such series surrendered in
         exchange for Registered Securities of

                           (ii) will become due and payable at their Stated
                  Maturity within one year; or

                           (iii) if redeemable at the option of the Company, are
                  to be called for redemption within one year under arrangements
                  satisfactory to the Trustee for the giving of notice of

                  the Company;

         and the Company, in the case of (i), (ii) or (iii) above, has deposited
         or caused to be deposited with the Trustee as trust funds in trust for
         such purpose, money in the Currency in which such Securities are

         indebtedness on such Securities and any Coupons appertaining thereto
         not theretofore delivered to the Trustee for cancellation, including
         the principal of, any premium and interest on, and any Additional
         Amounts with respect to such Securities and any Coupons appertaining

         payable hereunder by the Company with respect to the Outstanding
         Securities of such series and any Coupons appertaining thereto; and

         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture as to such series have been complied with.

         In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.



                                       34
<PAGE>   43

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 606 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section 401, the
obligations of the Company and the Trustee with respect to the Securities of
such series under Sections 305, 306, 403, 1002, 1003 and Article Twelve, with
respect to the payment of Additional Amounts, if any, with respect to such
Securities as contemplated by Section 1004 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to subclause (b) of
clause (1) of this Section 401), and, unless otherwise provided pursuant to
Section 301 with respect to the Securities of such series, any rights to convert
or exchange the Securities of such series into other securities or rights in
accordance with their terms, shall survive.

         Section 402. Defeasance and Covenant Defeasance.

         defeasance of the Securities of or within a series under clause (2) of
         this Section 402, or (ii) covenant defeasance of the Securities of or
         within a series under clause (3) of this Section 402 shall be
         applicable with respect to the Securities of such series, then such
         provisions, together with the other provisions of this Section 402
         (with such modifications thereto as may be specified pursuant to
         Section 301 with respect to any Securities), shall be applicable to
         such Securities and any Coupons appertaining thereto, and the Company
         may at its option by Board Resolution or Officers' Certificate, at any
         time, with respect to such Securities and any Coupons appertaining
         thereto, elect to have Section 402(2) or Section 402(3) be applied to
         such Outstanding Securities and any Coupons appertaining thereto upon
         compliance with the conditions set forth below in this Section 402.

                  (2) Upon the Company's exercise of the above option applicable
         to this Section 402(2) with respect to any Securities of or within a
         series, the Company shall be deemed to have been discharged from its

         appertaining thereto on the date the conditions set forth in clause (4)
         of this Section 402 are satisfied (hereinafter, "defeasance"). For this
         purpose, such defeasance means that the Company shall be deemed to have
         paid and discharged the entire Indebtedness represented by such

         shall thereafter be deemed to be "Outstanding" only for the purposes of
         clause (5) of this Section 402 and the other Sections of this Indenture
         referred to in clauses (i) and (ii) below, and to have satisfied all of
         its other obligations under such Securities and any Coupons
         appertaining thereto and this Indenture insofar as such Securities and
         any Coupons appertaining thereto are concerned (and the Trustee, at the
         expense of the Company, shall execute proper instruments acknowledging
         the same), except for the following which shall survive until otherwise
         terminated or discharged hereunder: (i) the rights of Holders of such
         Outstanding Securities and any Coupons appertaining thereto to receive,
         solely from the trust fund described in clause (4) of this Section 402
         and as more fully set forth in such Section, payments in respect of the
         principal of (and premium, if any) and interest, if any, on, and
         Additional Amounts, if any, with respect to, such Securities and any
         Coupons appertaining thereto when such payments are due, and any rights
         of such Holder to convert or exchange such Securities

         into Common Stock or other Securities, (ii) the obligations of the
         Company and the Trustee with respect to such Securities under Sections
         305, 306, 1002 and 1003, with respect to the payment of Additional
         Amounts, if any, on such Securities as contemplated by Section 1004
         (but only to the extent that the Additional Amounts payable with
         respect to such Securities exceed the amount deposited in respect of
         such Additional Amounts pursuant to Section 402(4)(a) below), (iii) the
         rights, powers, trusts, duties and immunities of the Trustee hereunder
         and (iv) this Section 402. The Company may exercise its option under
         this Section 402(2) notwithstanding the prior exercise of its option
         under clause (3) of this Section 402 with respect to such Securities
         and any Coupons appertaining thereto.

                  (3) Upon the Company's exercise of the above option applicable
         to this Section 402(3) with respect to any Securities of or within a
         series, the Company shall, to the extent specified pursuant to Section
         301, be released from its obligations in respect of any covenant
         applicable to such Securities, with respect to such Outstanding
         Securities and any Coupons appertaining thereto on and after the date
         the conditions set forth in clause (4) of this Section 402 are
         satisfied (hereinafter, "covenant defeasance"), and such Securities and
         any Coupons appertaining thereto shall thereafter be deemed to be not
         "Outstanding" for the purposes of any direction, waiver, consent or
         declaration or Act of Holders (and the consequences of any thereof) in
         connection with any such covenant, but shall continue to be deemed
         "Outstanding" for all other purposes hereunder. For this purpose, such
         covenant defeasance means that, with respect to such Outstanding
         Securities and any Coupons appertaining thereto, the Company may omit
         to comply with, and shall have no liability in respect of, any term,
         condition or limitation set forth in any such Section or such other
         covenant, whether directly or indirectly, by reason of any reference
         elsewhere herein to any such Section or such other covenant or by
         reason of reference in any such Section or such other covenant to any
         other provision herein or in any other document and such omission to
         comply shall not constitute a default or an Event of Default under
         Section 501(4) or 501(6) or otherwise, as the case may be, but, except
         as specified above, the remainder of this Indenture and such Securities
         and Coupons appertaining thereto shall be unaffected thereby.

                  (4) The following shall be the conditions to application of
         clause (2) or (3) of this Section 402 to any Outstanding Securities of
         or within a series and any Coupons appertaining thereto:

                           (a) The Company shall irrevocably have deposited or
                  caused to be deposited with the Trustee (or another trustee
                  satisfying the requirements of Section 607 who shall agree to
                  comply with the provisions of this Section 402 applicable to
                  it) as trust funds in trust for the purpose of making the
                  following payments, specifically pledged as security for, and
                  dedicated solely to, the benefit of the Holders of such
                  Securities and any Coupons appertaining thereto:

                                    (1) an amount in Dollars or in such Foreign
                           Currency in which such Securities and any Coupons
                           appertaining thereto are then specified as payable at
                           Stated Maturity; or



                                       36
<PAGE>   45

                                    (2) Government Obligations applicable to
                           such Securities and Coupons appertaining thereto
                           (determined on the basis of the Currency in which
                           such Securities and Coupons appertaining thereto are
                           then specified as payable at Stated Maturity) which
                           through the scheduled payment of principal and
                           interest in respect thereof in accordance with their
                           terms will provide, not later than one day before the
                           due date of any payment of principal of and any
                           premium, interest and Additional Amounts on such
                           Securities and any Coupons appertaining thereto,
                           money in an amount; or

                                    (3) a combination thereof;

                           in any case, in an amount, sufficient, without
                           consideration of any reinvestment of such principal
                           and interest, in the opinion of a nationally
                           recognized firm of independent public accountants
                           expressed in a written certification thereof
                           delivered to the Trustee, to pay and discharge, and
                           which shall be applied by the Trustee (or other
                           qualifying trustee) to pay and discharge, the
                           principal of and any premium, interest and Additional
                           Amounts on such Outstanding Securities and any
                           Coupons appertaining thereto on the Stated Maturity
                           of such principal or installment of principal or
                           interest on the day on which such payments are due
                           and payable in accordance with the terms of this
                           Indenture and of such Securities and any Coupons
                           appertaining thereto.

                           (b) Such defeasance or covenant defeasance shall not
                  result in a breach or violation of, or constitute a default
                  under, this Indenture or any other material agreement or
                  instrument to which the Company is a party or by which it is
                  bound.

                           (c) No Event of Default or event which with notice or
                  lapse of time or both would become an Event of Default with
                  respect to such Securities and any Coupons appertaining
                  thereto shall have occurred and be continuing on the date of
                  such deposit and, with respect to defeasance only, at any time
                  during the period ending on the 91st day after the date of
                  such deposit (it being understood that this condition shall
                  not be deemed satisfied until the expiration of such period).

                           (d) In the case of an election under clause (2) of
                  this Section 402, the Company shall have delivered to the
                  Trustee an Opinion of Counsel stating that (i) the Company has
                  received from the Internal Revenue Service a letter ruling, or
                  there has been published by the Internal Revenue Service a
                  Revenue Ruling, or (ii) since the date of execution of this
                  Indenture, there has been a change in the applicable Federal
                  income tax law, in either case to the effect that, and based
                  thereon such opinion shall confirm that, the Holders of such
                  Outstanding Securities and any Coupons appertaining thereto
                  will not recognize income, gain or loss for Federal income tax
                  purposes as a result of such defeasance and will be subject to
                  Federal income tax on the same amounts, in the same manner and
                  at the same times as would have been the case if such
                  defeasance had not occurred.

                           (e) In the case of an election under clause (3) of
                  this Section 402, the Company shall have delivered to the
                  Trustee an Opinion of Counsel to the effect that the Holders
                  of such Outstanding Securities and any Coupons appertaining
                  thereto will not recognize income, gain or loss for Federal
                  income tax purposes as a result of such covenant defeasance
                  and will be subject to Federal income tax on the same amounts,
                  in the same manner and at the same times as would have been
                  the case if such covenant defeasance had not occurred.

                           (f) The Company shall have delivered to the Trustee
                  an Officers' Certificate and an Opinion of Counsel, each
                  stating that all conditions precedent to the defeasance or
                  covenant defeasance under clause (2) or (3) of this Section
                  402 (as the case may be) have been complied with.

                           (g) Notwithstanding any other provisions of this
                  Section 402(4), such defeasance or covenant defeasance shall
                  be effected in compliance with any additional or substitute
                  terms, conditions or limitations which may be imposed on the
                  Company in connection therewith pursuant to Section 301.

                  (5) Subject to the provisions of the last paragraph of Section
         1003, all money and Government Obligations (or other property as may be
         provided pursuant to Section 301) (including the proceeds thereof)
         deposited with the Trustee (or other qualifying trustee, collectively
         for purposes of this Section 402(5) and Section 403, the "Trustee")
         pursuant to clause (4) of Section 402 in respect of any Outstanding
         Securities of any series and any Coupons appertaining thereto shall be
         held in trust and applied by the Trustee, in accordance with the
         provisions of such Securities and any Coupons appertaining thereto and
         this Indenture, to the payment, either directly or through any Paying
         Agent (including the Company acting as its own Paying Agent) as the
         Trustee may determine, to the Holders of such Securities and any
         Coupons appertaining thereto of all sums due and to become due thereon
         in respect of principal of and any premium, interest and Additional
         Amounts, but such money need not be segregated from other funds except
         to the extent required by law.

         Unless otherwise specified in or pursuant to this Indenture or any
Security, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of and any premium and interest on, and any Additional
Amounts with respect to, such Security as the same becomes due out of the
proceeds yielded by converting (from time to time as specified below in the case
of any such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on (x) in the case of payments made
pursuant to clause (a) above, the



                                       38
<PAGE>   47

applicable market exchange rate for such Currency in effect on the second
Business Day prior to each payment date, or (y) with respect to a Conversion
Event, the applicable market exchange rate for such Foreign Currency in effect
(as nearly as feasible) at the time of the Conversion Event. Unless otherwise
provided pursuant to Section 301, the right, if any, to extend an interest
payment period shall terminate upon defeasance or covenant defeasance, as the
case may be.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 402 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

         Anything in this Section 402 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in clause (4) of this Section 402 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Section 402.

         Section 403. Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations deposited with the Trustee pursuant to Section
401 or 402 shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the Coupons and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal, premium, interest and Additional Amounts for whose payment
such money has or Government Obligations have been deposited with or received by
the Trustee; but such money and Government Obligations need not be segregated
from other funds except to the extent required by law.

         Section 404. Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or other wise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to this Article shall be revived and reinstated as though no
deposit has occurred pursuant to this Article with respect to such Securities,
until such time as the Trustee or Paying Agent is permitted to apply all money
held in trust pursuant to this Article with respect to such Securities in
accordance with this Article; provided, however, that if the Company makes any
payment of principal of or any premium or interest on or Additional Amounts with
respect to any such Security following reinstatement of its obligations, the
Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable; provided that in the
case of a series of Securities then held by a Trust, if upon an Event of Default
with respect to the Securities of that series the Trustee has, or the Holders of
not less than 25% in principal amount of the Outstanding Securities of such
series have, failed to declare the principal of all the Securities of such
series to be due and payable immediately, the holders of not less than 25% in
aggregate liquidation amount of the outstanding Preferred Securities of that
Trust shall have such right by a notice in writing to the Company and to the
Trustee.

         If an Event of Default specified in clause (6) or (7) of Section 501
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

         At any time after Securities of any series have been accelerated and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such series
(subject to, in the case of any series of Securities held as 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 Trust Agreement of such Trust), by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if:

                  (1) the Company has paid or deposited with the Trustee a sum
         of money sufficient to pay:

                           (a) all overdue installments of any interest on and
                  Additional Amounts with respect to all Securities of such
                  series and any Coupon appertaining thereto;

                           (b) the principal of and any premium on any
                  Securities of such series which have become due otherwise than
                  by such declaration of acceleration and interest thereon and
                  any Additional Amounts with respect thereto at the rate or
                  rates borne by or provided for in such Securities;

                           (c) to the extent that payment of such interest or
                  Additional Amounts is lawful, interest upon overdue
                  installments of any interest and Additional Amounts at the
                  rate or rates borne by or provided for in such Securities; and

                           (d) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel and all other amounts due the Trustee under Section
                  606; and

                  (2) all Events of Default with respect to Securities of such
         series, other than the non-payment of the principal of, any premium and
         interest on, and any Additional Amounts with respect to Securities of
         such series which shall have become due solely by such declaration of
         acceleration, shall have been cured or waived as provided in Section
         513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

         Section 503. Collection of Indebtedness and Suits for Enforcement by
Trustee.

         The Company covenants that if:

                  (1) there is a failure to pay any installment of interest on
         or any Additional Amounts with respect to any Security or any Coupon
         appertaining thereto when such interest or Additional Amounts shall
         have become due and payable and such default continues for a period of
         30 days; or

                  (2) there is a failure to pay the principal of or any premium
         on any Security at its Maturity;

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and all other
amounts due to the Trustee under Section 606.

         If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and any Coupons
appertaining thereto and collect the monies adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other
obligor upon such Securities and any Coupons appertaining thereto, wherever
situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
and any Coupons appertaining thereto by such appropriate judicial proceedings as
the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

         Section 504. Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any



                                       43
<PAGE>   52

overdue principal, premium, interest or Additional Amounts) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

                  (1) to file and prove a claim for the whole amount, or such
         lesser amount as may be provided for in the Securities of such series,
         of the principal and any premium, interest and Additional Amounts owing
         and unpaid in respect of the Securities and any Coupons appertaining
         thereto and to file such other papers or documents as may be necessary
         or advisable in order to have the claims of the Trustee (including any
         claim for the reasonable compensation, expenses, disbursements and
         advances of the Trustee, its agents or counsel) and of the Holders of
         Securities or any Coupons allowed in such judicial proceeding, and

                  (2) to collect and receive any monies 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 of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities or any Coupons, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security, or any Coupon in any such proceeding; provided, however, that the
Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors' committee or
other similar committee.

         Section 505. Trustee May Enforce Claim without Possession of Securities
                      or Coupons.

         All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of a
Security or Coupon in respect of which such judgment has been recovered

         Section 506.      Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any
premium, interest or Additional Amounts, upon

         predecessor Trustee under Section 606;

                  SECOND: To the payment of the amounts then due and unpaid upon
         the Securities and any Coupons for principal and any premium, interest
         and Additional Amounts 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 aggregate amounts due and payable on such
         Securities and Coupons for principal and any premium, interest and
         Additional Amounts, respectively;

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

         Section 507. Limitations on Suits.

         Except as provided in Section 508 or 516, no Holder of any Security of
any series or any Coupons appertaining thereto or holder of Preferred Securities
of the Trust, if any, that is the Holder of Securities of that series, shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee or for any
other remedy hereunder, unless:

                  (1) such Holder or holder of Preferred Securities has
         previously given written notice to the Trustee of a continuing Event of
         Default with respect to the Securities of such series;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of such series or the holders of not less
         than 25% in aggregate liquidation amount of such outstanding Preferred
         Securities shall have made written request to the Trustee to institute
         proceedings in respect of such Event of Default in its own name as
         Trustee hereunder;

                  (3) such Holder or Holders of such Outstanding Securities of
         such series or the holder or holders of such outstanding Preferred
         Securities have offered to the Trustee reasonable indemnity against the
         costs, expenses and liabilities to be incurred in compliance with such
         request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of such
         series or the holders of a majority in aggregate liquidation amount of
         such outstanding Preferred Securities;

it being understood and intended that no one or more of such Holders of such
Outstanding Securities of such series or the holder or holders of such
outstanding Preferred Securities shall



                                       45
<PAGE>   54

have any right in any manner whatever by virtue of, or by availing of, any
provision of this Indenture or any Security to affect, disturb or prejudice the
rights of any other such Holders or Holders of Securities of any other series or
holder or holders of Preferred Securities of another Trust, or to obtain or to
seek to obtain priority or preference over any other Holders of such Outstanding
Securities of such series or the holder or holders of such outstanding Preferred
Securities or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all such Holders or
holders.

         Section 508. Unconditional Right of Holders to Receive Principal and
                      any Premium, Interest and Additional Amounts.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject
to Sections 305 and 307) interest on, and any Additional Amounts with respect to
such Security or payment of such Coupon, as the case may be, on the respective
Stated Maturity or Maturities therefor specified in such Security or Coupon (or,
in the case of redemption, on the Redemption Date or, in the case of repayment
at the option of such Holder if provided in or pursuant to this Indenture, on
the date such repayment is due, or in the case of a Change in Control, or as to
any Change in Control Purchase Notice given timely, on the Change in Control
Purchase Date) and to convert or exchange such Security in accordance with its
terms, if applicable, and to institute suit for the enforcement of any such
payment or conversion or exchange, and such right shall not be impaired without
the consent of such Holder.

         Section 509. Restoration of Rights and Remedies.

         If the Trustee or any Holder of a Security or a Coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.

         Section 510. Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities or Coupons in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to each and every Holder of a Security or a Coupon is intended
to be exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

         Section 511. Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be,

         Section 512. Control by Holders of Securities.

         Subject to Section 601(5), the Holders of a majority in principal
amount of the Outstanding Securities of any series or, if that series of
Securities is held by a Trust, the holders of a majority in aggregate
liquidation amount of the Preferred Securities of that 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 the Securities of such series and any Coupons
appertaining thereto, provided that:

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or with the Securities of any series;

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction; and

                  (3) such direction is not unduly prejudicial to the rights of
         the other Holders of Securities of such series not joining in such
         action.

         Section 513. Waiver of Past Defaults.

         Subject to Section 502, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series, or, if that series
of Securities is held by a Trust, the holders of a majority in aggregate
liquidation amount of the Preferred Securities of that Trust, on behalf of the
Holders of all the Securities of such series and any Coupons appertaining
thereto, may waive any past or prospective default hereunder with respect to
such series and its consequences, except a default:

                  (1) in the payment of the principal of, any premium or
         interest on, or any Additional Amounts with respect to, any Security of
         such series or any Coupons appertaining thereto; or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

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



                                       47
<PAGE>   56

         Section 514. Waiver of Stay or Extension Laws.

         The Company covenants that (to the extent that it may lawfully do so)
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company expressly waives (to the extent
that it may lawfully do so) all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

         Section 515. Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his 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,
against any party litigant in such suit having due regard to the merits and good
faith of the claim or defenses made by such party litigant; but the provisions
of this Section 515 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or,
if a series of Securities is held by a Trust, the holders of more than 10%
aggregate liquidation amount of the Preferred Securities of that Trust, or to
any suit instituted by any Holder or holder of Preferred Securities, if any, for
the enforcement of the payment of the principal of or any premium or interest on
or Additional Amounts with respect to any Security on or after the respective
Stated Maturities expressed in such Security or pursuant to Section 516 (or, in
the case of redemption, on or after the Redemption Date, in the case of
repayment, on or after the date for repayment and, in the case of Change of
Control, on or after the date for payment of the Change of Control Purchase
Price).

         Section 516. Direct Action Right of Holders of Trust Preferred
                      Securities.

         If an Event of Default has occurred and is continuing and is
attributable either to (a) the failure of the Company to pay the principal of or
any premium or interest on or Additional Amounts with respect to the Securities
on the due date therefor or (b) the failure by the Company to deliver the
required securities or other property upon an appropriate conversion or exchange
right election, and an event of default has occurred and is continuing under the
applicable Trust Agreement, a holder of the related Preferred Securities, in
lieu of any action that may otherwise be taken hereunder as a Holder of
Securities, may institute a legal proceeding directly against the Company for
enforcement of payment to such holder of the principal of or any premium or
interest on or Additional Amounts with respect to such Securities having a
principal amount equal to the liquidation amount of the Preferred Securities
held by such holder or for enforcement of such conversion or exchange rights, as
the case may be (a "Direct Action"). Notwithstanding anything contained herein
to the contrary, the Company may not amend this Indenture to remove the
foregoing right to bring a Direct Action without the prior written



                                       48
<PAGE>   57

consent of the holders of all of the Preferred Securities outstanding.
Notwithstanding any payments made to a holder of Preferred Securities by the
Company in connection with a Direct Action, the Company shall remain obligated
to pay the principal of and any premium or interest on or Additional Amounts
with respect to the related Securities, and the Company shall be subrogated to
the rights of the holder of such Preferred Securities with respect to payments
on the Preferred Securities to the extent of any payments made by the Company to
such holder in any Direct Action.

                                   ARTICLE 6.

                                   THE TRUSTEE

         as provided therein) and any resolution of the Board of Directors may
         be sufficiently evidenced by a Board Resolution;

         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence shall be herein specifically prescribed)
         may, in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                  (4) the Trustee may consult with counsel and the written

         of the rights or powers vested in it by or pursuant to this Indenture
         at the request or direction of any of the Holders of Securities of any
         series or any Coupons appertaining thereto pursuant to this Indenture,

<PAGE>   58

         request, direction, consent, order, bond, security, coupon or other
         paper or document, but the Trustee, in its discretion, may make such
         further inquiry or investigation into such facts or matters as it may
         see fit, and, if the Trustee shall determine to make such further
         inquiry or investigation, it shall be entitled to examine, during
         business hours and upon reasonable notice, the books, records and
         promises of the Company, personally or by agent or attorney;

                  (7) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or

                  therefor by the Company or any such Holder; or

                           (c) the Trustee shall become incapable of acting or
                  shall be adjudged bankrupt or insolvent or a receiver of the

then, in any such case, (i) the Company, by or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder
of a Security who has been a bona fide Holder of a Security of such series for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with
respect to all Securities of such series and the appointment of a successor
Trustee or Trustees.

                  (5) If the Trustee shall resign, be removed or become
         incapable of acting, or if a vacancy shall occur in the office of
         Trustee for any cause, with respect to the Securities of one or more
         series, the Company, by or pursuant to a Board Resolution, shall
         promptly appoint a successor Trustee or Trustees with respect to the
         Securities of that or those series (it being understood that any such
         successor Trustee may be appointed with respect to the Securities of

         only one Trustee with respect to the Securities of any particular

         609. If, within one year after such resignation, removal or
         incapability, or the occurrence of such vacancy, a successor Trustee
         with respect to the Securities of any series shall be appointed by Act
         of the Holders of a majority in principal amount of the Outstanding
         Securities of such series delivered to the Company and the retiring
         Trustee, the successor Trustee so appointed shall, forthwith upon its
         acceptance of such appointment in accordance with the applicable
         requirements of Section 609, become the successor Trustee with respect
         to the Securities of such series and to that extent supersede the
         successor Trustee appointed by the Company. If no successor Trustee
         with respect to the Securities of any series shall have been so
         appointed by the Company or the Holders of Securities and accepted
         appointment in the manner required by Section 609, any Holder of a
         Security who has been a bona fide Holder of a Security of such series
         for at least six months may, on behalf of himself and all others
         similarly situated, petition any court of competent jurisdiction for
         the appointment of a successor Trustee with respect to the Securities
         of such series.

                  (6) The Company shall give notice of each resignation and each
         removal of the Trustee with respect to the Securities of any series and
         each appointment of a successor Trustee with respect to the Securities
         of any series by mailing written notice of such event by first-class
         mail, postage prepaid, to the Holders of Registered Securities, if any,
         of such series as their names and addresses appear in the Security
         Register and, if Securities of such series arc issued as Bearer
         Securities, by publishing notice of such event once in an Authorized
         Newspaper in each Place of Payment located outside the United States.
         Each notice shall include the name of the successor Trustee with
         respect to the Securities of such series and the address of its
         Corporate Trust Office.

         shall execute, acknowledge and deliver to the Company and the retiring

         successor Trustee relates, (2) if the retiring Trustee is not retiring
         with respect to all Securities, shall 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
         Securities of that or those series as to which the retiring Trustee is

         trust or trusts hereunder administered by any other such Trustee and

         Trustee shall become effective to the extent provided therein, such
         retiring Trustee shall 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 with respect to
         the Securities of that or those series to which the appointment of such
         successor Trustee relates other than as hereinafter expressly set
         forth, 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 with respect to the Securities of that
         or those series to which the appointment of such successor Trustee
         relates; but, on request of the Company or such successor Trustee, such
         retiring Trustee, upon payment of its charges with respect to the
         Securities of that or those series to which the appointment of such
         successor relates and subject to Section 1003 shall duly assign,
         transfer and deliver to such successor Trustee, to the extent

         supplemental indenture, the property and money held by such retiring
         Trustee hereunder with respect to the Securities of that or those
         series to which the appointment of such successor Trustee relates,
         subject to its claim, if any, provided for in Section 606.

                      Business.

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,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated
but not delivered by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment or pursuant to Section 306, and
Securities 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. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

         Each Authenticating Agent shall be acceptable to the Company and,
except as provided in or pursuant to this Indenture, shall at all times be a
corporation that would be permitted by the Trust Indenture Act to act as trustee
under an indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 611, it shall resign immediately in the manner and
with the effect specified in this Section 611.

converted or with which it may be consolidated, or any Corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any Corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such
Corporation shall be otherwise eligible under this Section 611, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 611, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall (i) mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Registered Securities, if any, of the series with respect to which
such Authenticating Agent shall serve, as their names and addresses appear in
the Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 611.

         The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section 611. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 606.

         The provisions of Sections 308, 603 and 604 shall be applicable to each
Authenticating Agent.

         If an Authenticating Agent is appointed with respect to one or more
series of Securities pursuant to this Section 611, the Securities of such series
may have endorsed thereon, in addition to or in lieu of the Trustee's
certificate of authentication, an alternate certificate of authentication in
substantially the following form:

to in the within-mentioned Indenture.

one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officers' Certificate by the Company), shall
appoint in accordance with this Section 611 an Authenticating Agent having an
office in a Place of Payment designated by the Company with respect to such
series of Securities.

         them to in any material respect; or

                  (4) to establish the form or terms of Securities of any series

         provision herein which may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to

         purposes of issue, authentication and delivery of Securities, as herein
         set forth; or

         the interests of any Holder of a Security of such series and any
         Coupons appertaining thereto or any other Security or Coupon in any
         material respect; or

                  (10) to secure the Securities; or

                  (11) to make provisions with respect to conversion or exchange
         rights of Holders of Securities of any series; or

                  (12) to amend or supplement any provision contained herein or
         in any supplemental indenture, provided that no such amendment or
         supplement shall materially adversely affect the interests of the
         Holders of any Securities then Outstanding.

         Section 902. Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture (and, in the case of any series of Securities held as
assets of a Trust, such consent of holders of the Preferred Securities and the
common securities of such Trust as may be required under the Trust Agreement of
such Trust), by Act of said Holders delivered to the Company and the Trustee,
the Company (when authorized by or pursuant to a Company's Board Resolution),
and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders of Securities of such series under this
Indenture or of the Securities of such series; provided, however, that no such
supplemental indenture, without the consent of the Holder of each Outstanding
Security affected thereby, shall:

                  (1) except as permitted by the terms of the Securities, change
         the Stated Maturity of the principal of, or any premium or installment
         of interest on or any Additional Amounts with respect to, any Security,
         or reduce the principal amount thereof or the rate (or modify the
         calculation of such rate) of interest thereon or any Additional Amounts
         with respect thereto, or any premium payable upon the redemption
         thereof or otherwise, or change the duration of the maximum consecutive
         period, if any, that payments of interest on such Securities may be
         deferred, if applicable, or change the obligation of the Company to pay
         Additional Amounts pursuant to Section 1004 (except as contemplated by
         Section 801(l) and permitted by Section 901(l)), or reduce the amount



                                       61
<PAGE>   70

         of the principal of an Original Issue Discount Security that would be
         due and payable upon a declaration of acceleration of the Maturity
         thereof pursuant to Section 502 or the amount thereof provable in
         bankruptcy pursuant to Section 504, change the redemption, conversion
         or exchange provisions or adversely affect the right of repayment at
         the option of any Holder as contemplated by Article Twelve, or change
         the subordination provisions that apply to the terms of such Securities
         in a manner adverse to Holders, or change the Place of Payment,
         Currency in which the principal of, any premium or interest on, or any
         Additional Amounts with respect to any Security is payable, or impair
         the right to institute suit for the enforcement of any such payment on
         or after the Stated Maturity thereof (or, in the case of redemption, on
         or after the Redemption Date or, in the case of repayment at the option
         of the Holder, on or after the date for repayment or in the case of
         change in control, after the Change in Control Purchase Date); or

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver (of compliance with certain
         provisions of this Indenture or certain defaults hereunder and their
         consequences) provided for in this Indenture, or reduce the
         requirements of Section 1404 for quorum or voting; or

                  (3) modify any of the provisions of this Section 902, Section
         513 or Section 1008, except to increase any such percentage or to
         provide that certain other provisions of this Indenture cannot be
         modified or waived without the consent of the Holder of each
         Outstanding Security affected thereby.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which shall have been included expressly and
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders of Securities under
this Section 902 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

         Section 903. Execution of Supplemental Indentures.

         As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article Nine or the
modifications thereby of the trust created by this Indenture, the Trustee shall

and (subject to Section 315 of the Trust Indenture Act) shall be fully protected
in relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

         Section 904. Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of a Security theretofore or thereafter authenticated and delivered hereunder
and of any Coupon appertaining thereto shall be bound thereby.

         Section 905. Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article Nine may, and
shall if required by the Trustee, bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee and the Company, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

         Section 906. Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

                                   ARTICLE 10.

                                    COVENANTS

         Section 1001. Payment of Principal, any Premium and Interest.

                  (1) The Company shall pay the principal of, any premium and
         interest on (including interest accruing during any extension period
         and/or on or after the filing of a petition in bankruptcy or
         reorganization relating to the Company, whether or not a claim for
         post-filing interest is allowed in such proceeding) and any Additional
         Amounts with respect to the Securities on or prior to the dates and in
         the manner provided in such Securities or pursuant to this Indenture.
         An installment of principal, and any premium, interest or Additional
         Amounts shall be considered paid on the applicable due date if on such
         date the Trustee or the Paying Agent holds, in accordance with this
         Indenture, money sufficient to pay all of such installment then due.
         With respect to any Security, the Company shall pay interest on overdue
         principal and interest on overdue installments of interest (including
         interest accruing during any extension period and/or on or after the
         filing of a petition in bankruptcy or reorganization relating to the
         Company, whether or not a claim for post-filing interest is allowed in
         such proceeding), or Additional Amounts to the extent lawful, at the
         rate accruing on such Security, compounded with the same frequency as
         interest is payable on such Securities. Interest on overdue interest
         shall accrue from the date such amounts become overdue.

                  (2) Notwithstanding the provisions of Section 1001 (1) or any
         other provision herein to the contrary, the Company shall have the
         right, as provided in an Officer's Certificate or supplemental
         indenture issued pursuant to Article Nine, in its sole and



                                       63
<PAGE>   72

         absolute discretion at any time and from time to time while the
         Securities of any series are outstanding, so long as no Event of
         Default with respect to such series of Securities has occurred and is
         continuing, to defer payments of interest by extending the interest
         payment period for such series of Securities for the maximum
         consecutive period, if any, specified for such series of Securities,
         provided that such extension period must end on an Interest Payment
         Date and shall not extend beyond the Stated Maturity or Redemption Date
         of any Security of such series, and provided further that at the end of
         each extension period the Company shall pay all interest then accrued
         and unpaid (together with interest thereon to the extent permitted by
         applicable law at the rate accruing on such Securities). Prior to the
         termination of an extension period, the Company may shorten or may
         further extend the interest payment period for such series of
         Securities, provided that such extension period together with all such
         previous and further extensions may not exceed the maximum consecutive
         period specified for such series of Securities, end on a date other
         than an Interest Payment Date or extend beyond the Stated Maturity or
         Redemption Date of any Security of such series. The Company shall give
         the Trustee notice of the Company's election to begin an extension
         period for any series of Securities and any shortening or extension
         thereof at least five Business Days prior to: (i) the date notice of
         payment of interest on such Securities is required to be given to any
         national securities exchange on which the related Preferred Securities,
         if any, or Securities are then listed or other applicable
         self-regulatory organization, or (ii) the date of the notice of the
         record or payment date of the related distribution on the Preferred
         Securities issued by the Trust which is the Holder of the Securities of
         such series, but in any event not less than five Business Days prior to
         the Record Date fixed by the Company for the payment of such interest.
         The Company shall give or cause the Trustee to give notice (a form of
         which shall be provided by the Company to the Trustee) of the Company's
         election to begin an extension period to the Holders by first class
         mail, postage prepaid.

         Section 1002. Maintenance of Office or Agency.

         The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series may be presented and surrendered in
the event of a conversion or exchange, and where notices and demands to or upon
the Company in respect of the Securities of such series relating thereto and
this Indenture may be served. If Securities of a series are issuable as Bearer
Securities, the Company shall maintain, subject to any laws or regulations
applicable thereto, an Office or Agency in a Place of Payment for such series
which is located outside the United States where Securities of such series and
any Coupons appertaining thereto may be presented and surrendered for payment;
provided, however, that if the Securities of such series are listed on The Stock
Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg
Stock Exchange or any other stock exchange located outside the United States and
such stock exchange shall so require, the Company shall maintain a Paying Agent
and a Conversion Agent, if applicable, in London, Luxembourg or any other
required city located outside the United States, as the case may be, so long as
the Securities of such series are listed on such exchange. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such Office or



                                       64
<PAGE>   73

Agency. 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 addresses
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of such series and any Coupons appertaining thereto may only be
presented and surrendered for payment at the place specified for the purpose
with respect to such Securities as provided in or pursuant to this Indenture,
and the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

         Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium, interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         The Company may also from time to time designate one or more other
Offices or Agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an Office
or Agency in each Place of Payment for Securities of any series for such
purposes. The Company shall give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other Office or Agency. Unless otherwise provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, The City of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Office or Agency of
the Company in the Borough of Manhattan, The City of New York for such purpose.
The Company may subsequently appoint a different Office or Agency in the Borough
of Manhattan, The City of New York for the Securities of any series.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one, exchange rate agent.

         Section 1003. Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the Currency or Currencies in
which



                                       65
<PAGE>   74
 the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the
principal of or any premium, interest or Additional Amounts so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and shall promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it shall, on or prior to each due date of the principal
of, any premium or interest on or any Additional Amounts with respect to any
Securities of such series, deposit with any Paying Agent a sum (in the Currency
or Currencies described in the preceding paragraph) sufficient to pay the
principal of or any premium, interest or Additional Amounts so becoming due,
such sum to be held in trust for the benefit of the Persons entitled thereto,
and (unless such Paying Agent is the Trustee) the Company will promptly notify
the Trustee of its action or failure so to act.

         The Company shall cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section 1003, that such Paying Agent shall:

                  (1) hold all sums held by it for the payment of the principal
         of, any premium or interest on or any Additional Amounts with respect
         to Securities of such series in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as provided in or pursuant to this Indenture;

                  (2) give the Trustee notice of any default by the Company (or
         any other obligor upon the Securities of such series) in the making of
         any payment of principal of, any premium or interest on or any
         Additional Amounts with respect to the Securities of such series; and

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

         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 by
Company Order direct a 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 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 sums.

         Except as otherwise provided herein or pursuant hereto, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amount shall have become
due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Security or any



                                       66
<PAGE>   75

Coupon appertaining thereto shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in an Authorized
Newspaper in each Place of Payment for such series or to be mailed to Holders of
Registered Securities of such series, or both, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication or mailing nor shall it be later than
two years after such principal and any premium or interest or Additional Amounts
shall have become due and payable, any unclaimed balance of such money then
remaining will be repaid to the Company.

         Section 1004. Additional Amounts.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts, if applicable, in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

         Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at least 10 days prior to the first Interest
Payment Date with respect to such series of Securities (or if the Securities of
such series shall not bear interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of
payment of principal or interest if there has been any change with respect to
the matters set forth in the below-mentioned Officers' Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if
other than the Trustee, an Officers' Certificate instructing the Trustee and
such Paying Agent or Paying Agents whether such payment of principal of and
premium, if any, or interest on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against any loss,
liability or expense reasonably incurred without negligence or bad faith on
their part arising out of or in connection with actions taken or omitted by any
of them in reliance on any Officers' Certificate furnished pursuant to this
Section 1004.

         Section 1005. No Restriction on Indebtedness or Liens.

         Nothing in this Indenture or in the Securities shall in any way
restrict or prevent the Company or any Subsidiary from issuing, assuming,
guaranteeing or otherwise incurring or securing any Indebtedness, or otherwise
granting any Liens in respect thereof.

         For purposes of this Section 1005, "Lien" shall mean, with respect to
any asset, any mortgage, lien, pledge, security interest or encumbrances of any
kind in respect of such asset, whether or not filed, recorded or otherwise
perfected under applicable law.

         Section 1006. Corporate Existence.

         Subject to Articles Eight and Fifteen, the Company shall do or cause to
be done all things necessary to preserve and keep in full force and effect its
corporate existence and that of each Subsidiary and their respective rights
(charter and statutory) and franchises; provided, however, that the foregoing
shall not obligate the Company or any Subsidiary to preserve any such right or
franchise if the Company or any Subsidiary shall determine that the preservation
thereof is no longer desirable in the conduct of its business or the business of
such Subsidiary.

         Section 1007. Payment of Expenses of Each Trust. The Company covenants
for the benefit of the Holders of each series of Securities owned by a Trust to
pay all of the obligations, costs and expenses of such Trust (other than
payments in respect of Trust Securities) in accordance with the provisions of
its Trust Agreement and to pay the taxes of such Trust in accordance with the
provisions of its Trust Agreement in order to permit such Trust to make
distributions on and redemptions of its Preferred Securities in accordance with
its Trust Agreement.

         Section 1008. Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 1001(2) or 1006 with respect
to the Securities of any series if before the time for such compliance the
Holders of at least a majority in principal amount of the Outstanding Securities
of such series, by Act of such Holders, either shall waive such compliance in
such instance or generally shall have waived compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

         Section 1009. Company Statement as to Compliance; Notice of Certain
Defaults.

                  (1) The Company shall deliver to the Trustee, within 120 days
         after the end of each fiscal year, a written statement (which need not
         be contained in or accompanied by an Officers' Certificate) signed by
         the principal executive officer, the principal financial officer or the
         principal accounting officer of the Company, stating that:



                                       68
<PAGE>   77

                           (a) a review of the activities of the Company during
                  such year and of its performance under this Indenture has been
                  made under his or her supervision; and

                           (b) to the best of his or her knowledge, based on
                  such review, (i) the Company has complied with all the
                  conditions and covenants imposed on it under this Indenture
                  throughout such year, or, if there has been a default in the
                  fulfillment of any such condition or covenant, specifying each
                  such default known to him or her and the nature and status
                  thereof, and (ii) no event has occurred and is continuing
                  which is, or after notice or lapse of time or both would
                  become, an Event of Default, or, if such an event has occurred
                  and is continuing, specifying each such event known to him and
                  the nature and status thereof.

                  (2) the Company shall deliver to the Trustee, within five days
         after the occurrence thereof, written notice of any Event of Default or
         any Default.

                                   ARTICLE 11.

                            REDEMPTION OF SECURITIES

         Section 1101. Applicability of Article.

         Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article Eleven.

         Section 1102. Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution or an Officers' Certificate. In case of any
redemption at the election of the Company of (a) less than all of the Securities
of any series or (b) all of the Securities of any series, with the same issue
date, interest rate or formula, Stated Maturity and other terms, the Company
shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed.

         Section 1103. Selection by Trustee of Securities to be Redeemed.

         If less than all of the Securities of any series with the same issue
date, interest rate or formula, Stated Maturity and other terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security of
such series established herein or pursuant hereto.



                                       69
<PAGE>   78

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal of such Securities which has been or is to be redeemed.

         Section 1104. Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed, to the Holders
of Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

         Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

         All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                  (3) if less than all Outstanding Securities of any series are
         to be redeemed, the identification (and, in the case of partial
         redemption, the principal amount) of the particular Security or
         Securities to be redeemed;

                  (4) in case any Security is to be redeemed in part only, the
         notice which relates to such Security shall state that on and after the
         Redemption Date, upon surrender of such Security, the Holder of such
         Security will receive, without charge, a new Security or Securities of
         authorized denominations for the principal amount thereof remaining
         unredeemed;

                  (5) that, on the Redemption Date, the Redemption Price shall
         become due and payable upon each such Security or portion thereof to be
         redeemed, and, if applicable, that interest thereon shall cease to
         accrue on and after said date;

                  (6) the place or places where such Securities, together (in
         the case of Bearer Securities) with all Coupons appertaining thereto,
         if any, maturing after the Redemption Date, are to be surrendered for
         payment of the Redemption Price and any accrued interest and Additional
         Amounts pertaining thereto;



                                       70
<PAGE>   79

                  (7) that, unless otherwise specified in such notice, Bearer
         Securities of any series, if any, surrendered for redemption must be
         accompanied by all Coupons maturing subsequent to the date fixed for
         redemption or the amount of any such missing Coupon or Coupons will be
         deducted from the Redemption Price, unless security or indemnity
         satisfactory to the Company, the Trustee and any Paying Agent is
         furnished;

                  (8) if Bearer Securities of any series are to be redeemed and
         any Registered Securities of such series are not to be redeemed, and if
         such Bearer Securities may be exchanged for Registered Securities not
         subject to redemption on the Redemption Date pursuant to Section 305 or
         otherwise, the last date, as determined by the Company, on which such
         exchanges may be made;

                  (9) that the redemption is out of a sinking fund, if such is
         the case;

                  (10) in the case of Securities of any series that are
         convertible or exchangeable into other securities or rights, the
         conversion or exchange price or rate, the date or dates on which or the
         period or periods during which the right to convert or exchange the
         principal of the Securities of such series to be redeemed will commence
         or terminate and the place or places where such Securities may be
         surrendered for conversion or exchange; and

                  (11) the CUSIP number or the Euroclear or the Clearstream
         Luxembourg reference numbers of such Securities, if any (or any other
         numbers used by a Depository to identify such Securities).

         A notice of redemption mailed as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         Section 1105. Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 1104, with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 301 or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

         Section 1106. Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the



                                       71
<PAGE>   80

Redemption Price and accrued interest) such Securities shall cease to bear
interest and the Coupons for such interest appertaining to any Bearer Securities
so to be redeemed, except to the extent provided below, shall be void. Upon
surrender of any such Security for redemption in accordance with said notice,
together with all Coupons, if any, appertaining thereto maturing after the
Redemption Date, such Security shall be paid by the Company at the Redemption
Price, together with any accrued interest and Additional Amounts to the
Redemption Date; provided, however, that, except as otherwise provided in or
pursuant to this Indenture or the Bearer Securities of such series, installments
of interest on Bearer Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable only upon presentation and surrender of Coupons
for such interest (at an Office or Agency located outside the United States
except as otherwise provided in Section 1002), and provided, further, that,
except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the Regular Record Dates therefor
according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing Coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such Security located outside of the United States except as
otherwise provided in Section 1002.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium, until paid,
shall bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

         Section 1107. Securities Redeemed in Part.

         Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing) and the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order



                                       72
<PAGE>   81

with respect thereto to the Trustee, without service charge, a new Security in
global form in a denomination equal to and in exchange for the unredeemed
portion of the principal of the Security in global form so surrendered.

                                   ARTICLE 12.

                       REPAYMENT AT THE OPTION OF HOLDERS

         Section 1201. Applicability of Article.

         Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 1201, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                                   ARTICLE 13.

                        SECURITIES IN FOREIGN CURRENCIES

         Section 1301. Applicability of Article.

         Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such

         Section 1401. Purposes for Which Meetings May Be Called.

         A meeting of Holders of Securities of any series may be called at any
time and from time to time pursuant to this Article Fourteen to make, give or
take any request, demand, authorization, direction, notice, consent, waiver or
other Act provided by this Indenture to be made, given or taken by Holders of
Securities of such series.

         Section 1402. Call, Notice and Place of Meetings.

                  (1) The Trustee may at any time call a meeting of Holders of
         Securities of any series for any purpose specified in Section 1401, to
         be held at such time and at such place in the Borough of Manhattan, The
         City of New York, or, if Securities of such series have been issued in
         whole or in part as Bearer Securities, in London or in such place
         outside the United States as the Trustee shall determine. Notice of
         every meeting of Holders of Securities of any series, setting forth the
         time and the place of such meeting and in general terms the action
         proposed to be taken at such meeting, shall be given in the manner

         to the date fixed for the meeting.

                  (2) In case at any time the Company (by or pursuant to a Board
         Resolution) or the Holders of at least 10% in principal amount of the
         Outstanding Securities of any series shall have requested the Trustee
         to call a meeting of the Holders of Securities of such series for any
         purpose specified in Section 1401, by written request setting forth in

         publication of the notice of such meeting within 21 days after receipt
         of such request (whichever shall be required pursuant to Section 106)
         or shall not thereafter proceed to cause the meeting to be held as
         provided herein, then the Company or the Holders of Securities of such
         series in the amount above specified, as the case may be, may determine
         the time and the place in the Borough of Manhattan, The City of New
         York, or, if Securities of such series are to be issued as Bearer

         Section 1404. Quorum; Action.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series, the Persons entitled
to vote 66-2/3% in principal amount of the Outstanding Securities of such series
shall constitute a quorum. In the absence of a quorum within 30 minutes after
the time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series, be dissolved. In any other
case, the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10 days
as determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any adjourned meeting shall be
given as provided in Section 1402(l), except that such notice need be given only
once not less than five days prior to the date on which the meeting is scheduled
to be reconvened. Notice of the reconvening of an adjourned meeting shall state
expressly the percentage, as provided above, of the principal amount of the
Outstanding Securities of such series which shall constitute a quorum.

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 902, any
resolution with respect to any consent or waiver which this Indenture expressly
provides may be given by the Holders of at least 66-2/3% in principal amount of
the Outstanding Securities of a series may be adopted at a meeting or an
adjourned meeting duly convened and at which a quorum is present as aforesaid
only by the affirmative vote of the Holders of 66-2/3% in principal amount of
the Outstanding Securities of that series; and provided, further, that, except
as limited by the proviso to Section 902, any resolution with respect to any
request, demand, authorization, direction, notice, consent, waiver or other Act
which this Indenture expressly provides may be made, given or taken by the
Holders of a specified percentage, which is less than a majority, in principal
amount of the Outstanding Securities of a series may be adopted at a meeting or
an adjourned meeting duly reconvened and at which a quorum is present as
aforesaid by the affirmative vote of the Holders of such specified percentage in
principal amount of the Outstanding Securities of such series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section 1404 shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

         Section 1405. Determination of Voting Rights, Conduct and Adjournment
                       of Meetings.

                  (1) Notwithstanding any other provisions of this Indenture,
         the Trustee may make such reasonable regulations as it may deem
         advisable for any meeting of Holders of



                                       75
<PAGE>   84

         Securities of such series in regard to proof of the holding of
         Securities of such series and of the appointment of proxies and in
         regard to the appointment and duties of inspectors of votes, the
         submission and examination of proxies, certificates and other evidence
         of the right to vote, and such other matters concerning the conduct of
         the meeting as it shall deem appropriate. Except as otherwise permitted
         or required by any such regulations, the holding of Securities shall be
         proved in the manner specified in Section 104 and the appointment of
         any proxy shall be proved in the manner specified in Section 104 or by
         having the signature of the person executing the proxy witnessed or
         guaranteed by any trust company, bank or banker authorized by Section
         104 to certify to the holding of Bearer Securities. Such regulations
         may provide that written instruments appointing proxies, regular on
         their face, may be presumed valid and genuine without the proof
         specified in Section 104 or other proof.

                  (2) The Trustee shall, by an instrument in writing, appoint a
         temporary chairman of the meeting, unless the meeting shall have been
         called by the Company or by Holders of Securities as provided in
         Section 1402(2), in which case the Company or the Holders of Securities
         of the series calling the meeting, as the case may be, shall in like
         manner appoint a temporary chairman. A permanent chairman and a
         permanent secretary of the meeting shall be elected by vote of the
         Persons entitled to vote a majority in principal amount of the
         Outstanding Securities of such series represented at the meeting.

                  (3) At any meeting, each Holder of a Security of such series
         or proxy shall be entitled to one vote for each $1,000 principal amount
         of Securities of such series held or represented by him; provided,
         however, that no vote shall be cast or counted at any meeting in
         respect of any Security challenged as not Outstanding and ruled by the
         chairman of the meeting to be not Outstanding. The chairman of the
         meeting shall have no right to vote, except as a Holder of a Security
         of such series or proxy.

                  (4) Any meeting of Holders of Securities of any series duly
         called pursuant to Section 1402 at which a quorum is present may be
         adjourned from time to time by Persons entitled to vote a majority in
         principal amount of the Outstanding Securities of such series
         represented at the meeting; and the meeting may be held as so adjourned
         without further notice.

         Section 1406. Counting Votes and Recording Action of Meetings.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the



                                       76
<PAGE>   85

meeting and showing that said notice was given as provided in Section 1402 and,
if applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                  disposing of Securities within the meaning of Rule 13D-5(b)(1)
                  under the Exchange Act of 1934), together with its Affiliates

                  pursuant to the Exchange Act of 1934 disclosing that such
                  person has become the beneficial owner (as the term
                  "beneficial owner" is defined in Rule 13d-3 under the Exchange
                  Act of 1934, or any successor provision) of either (A) 50% or

                  or more of the voting power of the Voting Stock of the Company
                  then outstanding; provided, however, that for purposes of
                  paragraph (a) of this Section 1501(1), a person shall not be
                  deemed the beneficial owner of (1) any Securities tendered
                  pursuant to a tender offer or exchange offer made by or on
                  behalf of such person, or its Affiliates or Associates, until
                  such tendered Securities are accepted for purchase or exchange
                  thereunder, or (2) any Securities in respect of which
                  beneficial ownership by such person arises solely as a result
                  of a revocable proxy delivered in response to a proxy or
                  consent solicitation that is made pursuant to, and in
                  accordance with, the Exchange Act of 1934 and the applicable
                  rules and regulations thereunder and is not then reportable on
                  Schedule 13D (or any successor schedule, form or report) under

                  or Corporations or other person or persons (other than a
                  Subsidiary of the Company);

                           (c) There shall be consummated any consolidation of
                  the Company with or merger of the Company with or into any
                  other Person (whether or not affiliated with the Company) in
                  which the Company is not the sole surviving or continuing
                  corporation or pursuant to which the shares of Common Stock
                  outstanding immediately prior to the consummation of such
                  consolidation or merger are converted into cash, securities or
                  other property, other than a consolidation or merger in which

                  thereof of such consolidation or merger.

         "Exchange Act of 1934" shall mean the Securities Exchange Act of 1934,
as amended.

         "Associate" shall have the meaning ascribed to such term in Rule 12b-2

         in Control, the Company shall mail a written notice of Change in
         Control by first-class mail to the Trustee and to each Holder (and to
         beneficial owners as required by applicable law, including, without
         limitation, Rule 13c-4 under the Securities Exchange Act of 1934) and,
         if any Bearer Securities are then outstanding, shall cause a copy of

         Authorized Newspaper in such city as the stock exchange so requires.
         The notice shall include or transmit a form of Change in Control
         Purchase Notice (as described below) to be completed by the Holder and
         shall state:

                  Office or Agency;



                                       78
<PAGE>   87

                           (f) that the Securities must be surrendered to the
                  Trustee or the Office or Agency to collect payment;

                           (g) that the Change in Control Purchase Price for any
                  Security as to which a Change in Control Purchase Notice has
                  been duly given and not withdrawn will be paid promptly
                  following the later of the Change in Control Purchase Date or

                  1501(2)(f);

                           (h) the procedures the Holder must follow to exercise

         Control Purchase Notice") to the Trustee or to the Office or Agency at
         any time prior to the close of business of the Change in Control
         Purchase Date, stating:

                           (a) the certificate number or numbers of the Security

         The delivery of the Security, by hand or by registered mail prior to,
on or after the Change in Control Purchase Date (together with all necessary
endorsements), to the Trustee or to the Office or Agency shall be a condition
precedent to the obligation of the Company to pay to the Holder the Change in
Control Purchase Price therefor; provided, however, that such Change in Control
Purchase Price shall be so paid pursuant to this Section 1501 only if the
Security so delivered to the Trustee or such Office or Agency shall conform in
all respects to the description thereof set forth in the related Change in
Control Purchase Notice.

         Notwithstanding anything herein to the contrary, any Holder delivering
to the Trustee or to the Office or Agency, the Change in Control Purchase Notice

Change in Control Purchase Notice at any time prior to or on the Change in

         Section 1502. Effect of Change in Control Purchase Notice.

         Upon receipt by the Company of the Change in Control Purchase Notice

thereafter be entitled to receive solely the Change in Control Purchase Price
with respect to such Security. Such Change in Control Purchase Price shall be

Purchase Date, as the case may be, with respect to such Security (provided the
conditions in Section 1501(3), as applicable, have been satisfied) and (y) the
time of delivery of such Security to the Trustee or to the Office or Agency by
the Holder thereof in the manner required by Section 1501(3) as applicable.

         Securities which remains subject to the original Change in Control
         Purchase Notice, and which has been and will be delivered for purchase
         by the Company.

         There shall be no purchase of any Securities pursuant to Section 1501
if there has occurred and is continuing an Event of Default (other than a

         Section 1503. Deposit of Change in Control Purchase Price.

         Prior to 12:00 Noon (local time in The City of New York) on the
Business Day following the Change in Control Purchase Date, the Company shall
deposit with the Trustee (or, if the Company or a Subsidiary or an Affiliate of

provided in Section 1003) an amount of cash in immediately available funds or
Securities, if expressly permitted hereunder, sufficient to pay the aggregate
Change in Control Purchase Price of all the Securities or portions thereof which

which a Change in Control Purchase Notice has been delivered and not validly
withdrawn shall become due and payable as of the Business Day following the
applicable Change in Control Purchase Date, and on and after such date interest
payable in respect of such Securities shall cease and all other rights of the
Holders thereof shall terminate, other than the right to receive the Change in
Control Purchase Price upon delivery of such Securities to the Trustee.

         Section 1504. Covenant to Comply With Securities Laws Upon Purchase of
                       Securities.

         In connection with any purchase of Securities under Section 1501
hereof, the Company shall (a) comply with Rule 13e-4 under the Securities
Exchange Act of 1934, if applicable, (b) file the related Schedule 13E-4 (or any
successor schedule, form or report) under the Securities Exchange Act of 1934,
if applicable, and (c) otherwise comply with all Federal and state securities
laws regulating the purchase of the Securities (including positions of the
Commission under applicable no-action letters) so as to permit the rights and
obligation under Section 1501 to be exercised in the time and in the manner
specified in Section 1501 and 1502.

         Section 1505. Repayment to the Company.

         The Trustee shall return to the Company any cash, together with
interest or dividends, if any, thereon (subject to the provisions of Section
605) held by it for the payment of the Change in Control Purchase Price of the
Securities that remain unclaimed as provided in the Securities; provided,
however, that to the extent the aggregate amount of cash deposited by the
Company pursuant to Section 1503 exceeds the aggregate Change in Control
Purchase Price of the Securities or portions thereof to be purchased, then
promptly after the Change in Control Purchase Date, the Trustee shall return any
such excess to the Company together with interest or dividends, if any, thereon
(subject to the provisions of Section 605).

                                   ARTICLE 16.

                                  SUBORDINATION

         Section 1601. Securities Subordinated to Senior Indebtedness.

         Notwithstanding the provisions of Section 506 or any other provision
herein or in any Security, the Company and the Trustee and, by their acceptance
thereof, the Holders of the Securities (a) covenant and agree that all payments
by the Company of the principal of and any premium or interest on and any
Additional Amounts with respect to the Securities (other than Securities which
have been discharged pursuant to Article Four or Securities that provide for a
sinking fund pursuant to the Board Resolution, Officers' Certificate or
supplemental indenture establishing the series as to which such sinking fund is
applicable) shall be subordinated in accordance with the provisions of this
Article Sixteen in right of payment to the prior payment in full, in cash or
cash equivalents, of all amounts payable on, under or in connection with Senior
Indebtedness, and (b) acknowledge that holders of Senior Indebtedness are or
shall be relying on this Article Sixteen. Nothing herein or in any Security is
intended to or shall limit the amount of Senior Indebtedness the Company may
incur.

         Section 1602. Priority and Payment of Proceeds in Certain Events:
                       Remedies Standstill.

                  (1) Upon any payment or distribution of assets or securities
         of the Company, as the case may be, of any kind or character, whether
         in cash, property or securities, upon any dissolution or winding up or
         total or partial liquidation or reorganization of the Company, whether
         voluntary or involuntary, or in bankruptcy, insolvency, receivership or
         other proceedings, all amounts payable on, under or in connection with
         Senior



                                       81
<PAGE>   90

         Indebtedness (including any interest accruing on such Senior
         Indebtedness subsequent to the commencement of a bankruptcy,
         insolvency, receivership or similar proceeding) shall first be paid,
         ratably according to the aggregate amounts remaining unpaid on account
         of the principal of and any premium and interest on the Senior
         Indebtedness held or represented by each, to the extent necessary to
         make payment in full of all Senior Indebtedness remaining unpaid, in
         cash, or payment provided for in cash or cash equivalents, ratably
         according to the aggregate amounts remaining unpaid on account of the
         principal of and any premium and interest on the Senior Indebtedness
         held or represented by each, to the extent necessary to make payment in
         full of all Senior Indebtedness remaining unpaid, before the Holders or
         the Trustee on behalf of the Holders or the holders of Preferred
         Securities, if any, shall be entitled to receive from the Company any
         payment of principal of or any premium or interest on or Additional
         Amounts with respect to the Securities or distribution of any assets or
         securities.

                  (2) No direct or indirect payment by or on behalf of the
         Company of principal of or any premium or interest on or Additional
         Amounts with respect to the Securities (other than Securities which
         have been discharged pursuant to Article Four or Securities that
         provide for a sinking fund), whether pursuant to the terms of the
         Securities or upon acceleration or otherwise, shall be made if, at the
         time of such payment, there exists (a) a default in the payment of all
         or any portion of any Senior Indebtedness and the Trustee has received
         written notice thereof from the Company, from holders of Senior
         Indebtedness or from any trustee, representative or agent therefor, or
         (b) any other default affecting Senior Indebtedness as a result of
         which the maturity of Senior Indebtedness has been accelerated and the
         Trustee has received written notice from the Company, from holders of
         Senior Indebtedness or from any trustee, representative or agent
         therefor, and such default shall not have been cured or waived by or on
         behalf of the holders of such Senior Indebtedness.

                  (3) If, notwithstanding the foregoing provisions prohibiting
         such payment or distribution, the Trustee or any Holder shall have
         received any payment on account of the principal of or any premium or
         interest on or Additional Amounts with respect to the Securities when
         such payment is prohibited by this Section 1602 and before all amounts
         payable on, under or in connection with Senior Indebtedness are paid in
         full in cash or cash equivalents, then and in such event (subject to
         the provisions of Section 1608) such payment or distribution shall be
         received and held in trust for the holders of Senior Indebtedness and,
         at the written direction of the trustee, representative or agent for
         the holders of the Senior Indebtedness, shall be paid to the holders of
         the Senior Indebtedness remaining unpaid to the extent necessary to pay
         such Senior Indebtedness in full in cash or cash equivalents.

         Upon any payment or distribution of assets or securities referred to in
this Article Sixteen, the Trustee and the Holders shall be entitled to rely upon
any order or decree of a court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending
or upon a certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making any such payment or distribution,
delivered to the Trustee or to the Holders for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of Senior
Indebtedness and other Indebtedness of the Company, the



                                       82
<PAGE>   91

amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Sixteen.

         Section 1603. Payments which May Be Made Prior to Notice.

         Nothing in this Article Sixteen or elsewhere in this Indenture shall
prevent (1) the Company, except under the conditions described in Section 1602,
from making payments of principal of or any premium or interest on or Additional
Amounts with respect to the Securities or from depositing with the Trustee any
monies for such payments, or (2) the application by the Trustee of any monies
deposited with it for the purpose of making such payments of principal of or any
premium or interest on or Additional Amounts with respect to the Securities, to
the Holders entitled thereto, unless at least two Business Days prior to the
date when such payment would otherwise (except for the prohibitions contained in
Section 1602) become due and payable, the Trustee shall have received the
written notice provided for in Section 1602(2)(a) or (b).

         Section 1604. Rights of Holders of Senior Indebtedness Not to Be
                       Impaired.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time or in any way be
prejudiced or impaired by any act or failure to act in good faith by any such
holder, or by any noncompliance by the Company with the terms and provisions and
covenants herein regardless of any knowledge thereof any such holder may have or
otherwise be charged with.

         The provisions of this Article Sixteen are intended to be for the
benefit of, and shall be enforceable directly by, the holders of Senior
Indebtedness. Notwithstanding anything to the contrary in this Article Sixteen,
to the extent any Holders or the Trustee have paid over or delivered to any
holder of Senior Indebtedness any payment or distribution received on account of
the principal of or any premium or interest on or Additional Amounts with
respect to the Securities to which any other holder of Senior Indebtedness shall
be entitled to share in accordance with Section 1602, no holder of Senior
Indebtedness shall have a claim or right against any Holders or the Trustee with
respect to any such payment or distribution or as a result of the failure to
make payments or distributions to such other holder of Senior Indebtedness.

         Section 1605. Trustee May Take Action to Effectuate Subordination.

         Each Holder of a Security, by his acceptance thereof, authorizes and
directs the Trustee on his behalf to take such action as may be required by the
trustee, representative or agent for holders of Senior Indebtedness or by the
Company to effectuate, as between the holders of Senior Indebtedness and the
Holders, the subordination as provided in this Article Sixteen and appoints the
Trustee his attorney-in-fact for any and all such purposes.

         Section 1606. Subrogation.

         Upon the payment in full, in cash or cash equivalents, of all Senior
Indebtedness, any Holder shall be subrogated to the rights of the holders of
such Senior Indebtedness to receive payments or distributions of assets of the
Company in respect of such Senior Indebtedness until the Securities shall be
paid in full; and for the purposes of such subrogation, no payments or



                                       83
<PAGE>   92

distributions to holders of such Senior Indebtedness of any cash property or
securities to which such Holders of the Securities would be entitled except for
this Article Sixteen, and no payment pursuant to this Article Sixteen to holders
of such Senior Indebtedness by such Holders of the Securities, shall, as between
the Company, its creditors other than holders of such Senior Indebtedness and
such Holders of the Securities, be deemed to be a payment by the Company to or
on account of such Senior Indebtedness, it being understood that the provisions
of this Article Sixteen are solely for the purpose of defining the relative
rights of the holders of such Senior Indebtedness, on the one hand, and such
Holders of the Securities, on the other hand.

         If any payment or distribution to which Holders of Securities would
otherwise have been entitled but for the provisions of this Article Sixteen
shall have been applied, pursuant to this Article Sixteen, to the payment of all
Senior Indebtedness, then and in such case such Holders of the Securities shall
be entitled to receive from the holders of such Senior Indebtedness at the time
outstanding any payments or distributions received by such holders of Senior
Indebtedness in excess of the amount sufficient to pay, in cash or cash
equivalents, all such Senior Indebtedness in full.

         Section 1607. Obligations of Company Unconditional; Reinstatement.

         Nothing in this Article Sixteen or elsewhere in this Indenture or in
any Security is intended to or shall impair, as among the Company, its creditors
other than holders of Senior Indebtedness and Holders of the Securities, the
obligations of the Company, which are absolute and unconditional, to pay to such
Holders the principal of and any premium and interest on and Additional Amounts
with respect to the Securities 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 such Holders of the Securities and creditors of the Company other than
the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or any Holder of Securities or holder of Preferred
Securities, as applicable, from exercising all remedies otherwise permitted by
applicable law under this Indenture, subject to the rights, if any, under this
Article Sixteen of the holders of such Senior Indebtedness in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy.

         The failure to make a scheduled payment of principal of or any premium
or interest on or Additional Amounts with respect to the Securities by reason of
Section 1602 shall not be construed as preventing the occurrence of a Default or
an Event of Default under Section 501; provided, however, that if (1) the
conditions preventing the making of such payment no longer exist, and (2) such
Holders of the Securities are made whole with respect to such omitted payments,
the Default or Event of Default relating thereto (including any failure to pay
any accelerated amounts) shall be automatically waived, and the provisions of
the Indenture shall be reinstated as if no such Event of Default had occurred.

         Section 1608. Trustee Entitled to Assume Payments Not Prohibited in
                       Absence of Notice.

         The Trustee or Paying Agent shall not be charged with the knowledge of
the existence of any default in the payment of all or a portion of any Senior
Indebtedness or any other default affecting Senior Indebtedness as a result of
which the maturity of the Senior Indebtedness has been accelerated, unless and
until the Trustee or Paying Agent shall have received written notice



                                       84
<PAGE>   93

thereof from the Company or one or more holders of Senior Indebtedness or from
any trustee, representative or agent therefor; and, prior to the receipt of any
such written notice, the Trustee or Paying Agent may conclusively assume that no
such facts exist.

         Unless at least two Business Days prior to the date when by the terms
of this Indenture any monies are to be deposited by the Company with the Trustee
or any Paying Agent for any purpose (including, without limitation, the payment
of the principal of or any premium or interest on or Additional Amounts with
respect to any Security), the Trustee or Paying Agent shall have received with
respect to such monies the notice provided for in Section 1602, the Trustee or
Paying Agent shall have full power and authority to receive and apply such
monies to the purpose for which they were received. Neither of them shall be
affected by any notice to the contrary, which may be received by either on or
after such second Business Day. The foregoing shall not apply to the Paying
Agent if the Company is acting as Paying Agent. Nothing in this Section 1608
shall limit the right of the holders of Senior Indebtedness to recover payments
as contemplated by Section 1602. The Trustee or Paying Agent shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself or itself to be a holder of such Senior Indebtedness (or a trustee,
representative or agent on behalf of such holder) to establish that such notice
has been given by a holder of such Senior Indebtedness or a trustee,
representative or agent on behalf of any such holder. The Trustee shall not be
deemed to have any fiduciary duty to the holders (and shall be fully protected
in relying upon such notice) of Senior Indebtedness.

         Section 1609. Right of Trustee to Hold Senior Indebtedness.

         The Trustee and any Paying Agent shall be entitled to all of the rights
set forth in this Article Sixteen in respect of any Senior Indebtedness at any
time held by them, to the same extent as any other holder of such Senior
Indebtedness, and nothing in this Indenture shall be construed to deprive the
Trustee or any Paying Agent of any of its rights as such holder.

         Section 1610. Notice to Trustee.

         The Company shall give prompt written notice to the Trustee or Paying
Agent of any fact known to the Company which would prohibit the making of any
payment to or by the Trustee in respect of the Securities. Failure to give such
notice shall not affect the subordination of the Securities to Senior
Indebtedness. Notwithstanding the provisions of this or any other provision of
this Indenture, the Trustee or Paying Agent shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee or Paying Agent in respect of the Securities, unless and until
the Trustee or Paying Agent shall have received written notice from the Company
or a holder of Senior Indebtedness or from any trustee or agent therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 601, or Paying Agent shall be entitled in all respects to
assume that no such facts exist; provided, however, that if a Responsible
Officer of the Trustee or Paying Agent shall not have received, at least three
Business Days prior to the date upon which by the terms hereof any such money
may become payable for any purpose (including, without limitation, the payment
of the principal of or any premium or interest on or Additional Amounts with
respect to any Security, the notice with respect to such money provided for in
this Section 1610, then, anything herein contained to the contrary
notwithstanding, the Trustee or Paying Agent shall have full power and authority
to receive such money and to apply the same to the purpose for



                                       85
<PAGE>   94

which such money was received and shall not be affected by any notice to the
contrary which may be received by it within three Business Days prior to such
date.

         The Trustee, subject to the provisions of Section 601, or Paying Agent
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself or itself to be a holder of Senior Indebtedness
(or a trustee or agent on behalf of such holder) to establish that such notice
has been given by a holder of Senior Indebtedness (or a trustee or agent on
behalf of any such holder). In the event that the Trustee or Paying Agent
determines in good faith that further evidence is required with respect to the
right of any Person as a holder of Senior Indebtedness to participate in any
payment or distribution pursuant to this Article Sixteen, the Trustee or Paying
Agent may request such Person to furnish evidence to the reasonable satisfaction
of the Trustee or Paying Agent as to the amount of Senior Indebtedness 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 Sixteen, and if such evidence is not furnished, the
Trustee or Paying Agent may defer any payment which it may be required to make
for the benefit of such Person pursuant to the terms of this Indenture pending
judicial determination as to the rights of such Person to receive such payment.

         Section 1611. Reliance on Judicial Order or Certificate of Liquidating
                       Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article Sixteen, the Trustee, subject to the provisions of Section 601,
and the Holders of the Securities shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, liquidating trustee, Custodian, receiver, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness 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
Sixteen.

         Section 1612. Trustee Not Fiduciary for Holders of Senior Indebtedness.

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if
the Trustee shall in good faith mistakenly pay over or distribute to Holders of
Securities or to the Company or to any other Person cash, property or securities
to which any holders of Senior Indebtedness shall be entitled by virtue of this
Article or otherwise. With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or to observe only such of its covenants or
obligations as are specifically set forth in this Article and no implied
covenants or obligations with respect to holders of Senior Indebtedness shall be
read into this Indenture against the Trustee.

         Nothing in this Article shall apply to claims of or payments to, the
Trustee under or pursuant to Section 606.

Guarantee"), dated as of ______________, is executed and delivered by Apache

trustee (the "Preferred Securities Guarantee Trustee"), for the benefit of the
Holders (as defined herein) from time to time of the Preferred Securities (as
defined herein) of Apache Trust [I/II], a Delaware statutory business trust (the
"Issuer").

                  WHEREAS, pursuant to an Amended and Restated Trust Agreement

                  WHEREAS, as incentive for the Holders to purchase the

forth herein; and

                  WHEREAS, the Guarantor is concurrently herewith executing and
delivering a guarantee agreement (the "Common Securities Guarantee") with

benefit of the holders of the Common Securities (as defined herein), except that
if an Event of Default (as defined in the Agreement), has occurred and is
continuing, the rights of holders of the Common Securities to receive Guarantee
Payments under the Common Securities Guarantee are subordinated to the rights of

                     PREFERRED SECURITIES GUARANTEE TRUSTEE

SECTION 3.1 Powers and Duties of the Preferred Securities Guarantee Trustee

                  (a) This Preferred Securities Guarantee shall be held by the
Preferred Securities Guarantee Trustee for the benefit of the Holders, and the
Preferred Securities Guarantee Trustee shall not transfer this Preferred
Securities Guarantee to any Person except a Holder exercising his or her rights
pursuant to Section 5.4(b) or to a Successor Preferred Securities Guarantee
Trustee on acceptance by such Successor Preferred Securities Guarantee Trustee
of its appointment to act as Successor Preferred Securities Guarantee Trustee.
The right, title and interest of the Preferred Securities Guarantee Trustee
shall automatically vest in any Successor Preferred Securities Guarantee
Trustee, and such vesting and succession of title shall be effective whether or
not conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Preferred Securities Guarantee Trustee.

                  (b) If an Event of Default actually known to a Responsible
Officer of the Preferred Securities Guarantee Trustee has occurred and is
continuing, the Preferred Securities Guarantee Trustee shall enforce this
Preferred Securities Guarantee for the benefit of the Holders.

                  (c) The Preferred Securities Guarantee Trustee, before the
occurrence of any Event of Default and after the curing or waiver of all Events
of Default that may have occurred, shall undertake to perform only such duties
as are specifically set forth in this Preferred Securities Guarantee, and no
implied covenants or obligations shall be read into this Preferred Securities
Guarantee against the Preferred Securities Guarantee Trustee. In case an Event
of Default has occurred (that has not been cured or waived pursuant to Section
2.6) and is actually known to a Responsible Officer of the Preferred Securities
Guarantee Trustee, the Preferred Securities Guarantee Trustee shall exercise
such of the rights and powers vested in it by this Preferred Securities
Guarantee, 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.

                  (d) No provision of this Preferred Securities Guarantee shall
be construed to relieve the Preferred Securities Guarantee Trustee from
liability for its own negligent action, its own negligent failure to act, its
own bad faith or its own willful misconduct, except that:

                           (i) prior to the occurrence of any Event of Default
                  and after the curing or waiving of such Events of Default that
                  may have occurred:

                                    (A) the duties and obligations of the
                           Preferred Securities Guarantee Trustee shall be
                           determined solely by the express provisions of this
                           Preferred Securities Guarantee, and the Preferred
                           Securities Guarantee Trustee shall not be liable
                           except for the performance of such duties and

                           obligations as are specifically set forth in this
                           Preferred Securities Guarantee, and no implied
                           covenants or obligations shall be read into this
                           Preferred Securities Guarantee against the Preferred
                           Securities Guarantee Trustee; and

                                    (B) in the absence of bad faith on the part
                           of the Preferred Securities Guarantee Trustee, the
                           Preferred Securities 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 Preferred Securities Guarantee Trustee and
                           conforming to the requirements of this Preferred
                           Securities Guarantee; but in the case of any such
                           certificates or opinions that by any provision hereof
                           are specifically required to be furnished to the

                           Securities Guarantee;

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

                           (iii) the Preferred Securities 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 not less than a Majority in
                  liquidation amount of the Preferred Securities relating to the
                  time, method and place of conducting any proceeding for any
                  remedy available to the Preferred Securities Guarantee
                  Trustee, or exercising any trust or power conferred upon the
                  Preferred Securities Guarantee Trustee under this Preferred
                  Securities Guarantee; and

                           (iv) no provision of this Preferred Securities
                  Guarantee shall require the Preferred Securities 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
                  the Preferred Securities Guarantee Trustee 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 Preferred Securities Guarantee or if indemnity
                  reasonably satisfactory to the Preferred Securities Guarantee
                  Trustee against such risk or liability is not reasonably
                  assured to it.

                  evidenced by the Preferred Securities Guarantee Trustee's or
                  its agent's taking such action;

                           (x) whenever in the administration of this Preferred

                           (iii) if an Event of Default shall have occurred and
                  be continuing, after the issuance of the Preferred Securities,
                  by vote or written consent of the Holders of a Majority in

                                    GUARANTEE

SECTION 5.1 Guarantee

                  The Guarantor irrevocably and unconditionally agrees to pay in

right of set-off or counterclaim that 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.

redemption, liquidation or other provision of the Debentures, the Other
Documents or the Preferred Securities.

SECTION 5.2 Waiver of Notice and Demand

                  The Guarantor hereby waives notice of acceptance of this
Preferred Securities Guarantee 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.

SECTION 5.3 Obligations Not Affected

                  The obligations, covenants, agreements and duties of the
Guarantor under this Preferred Securities Guarantee 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 any sums payable or the performance by the Issuer of any other
obligation under, arising out of, or in connection with, the Preferred
Securities (other than an extension of time permitted by the Indenture);

                  (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 5.3 that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.



                                       14
<PAGE>   19

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

SECTION 5.4 Rights of Holders

                  (a) The Holders of a Majority in liquidation amount of the
Preferred Securities have the right to direct the time, method and place of
conducting of any proceeding for any remedy available to the Preferred
Securities Guarantee Trustee in respect of this Preferred Securities Guarantee
or exercising any trust or power conferred upon the Preferred Securities
Guarantee Trustee under this Preferred Securities Guarantee.

                  (b) If the Preferred Securities Guarantee Trustee fails to
enforce this Preferred Securities Guarantee, any Holder may institute a legal
proceeding directly against the Guarantor to enforce its rights under this
Preferred Securities Guarantee, without first instituting a legal proceeding
against the Issuer, the Preferred Securities Guarantee Trustee or any other
Person. Notwithstanding the foregoing, if the Guarantor has failed to make a
Guarantee Payment or to perform any of its other obligations under Section 5.1,
a Holder may directly institute a proceeding in the Holder's own name against
the Guarantor for enforcement of this Capital Security Guarantee for the portion
of such Guarantee Payment or the performance of such other obligation to which
such Holder is entitled. The Guarantor waives any right or remedy to require
that any action on this Preferred Securities Guarantee be brought first against
the Issuer or any other person or entity before proceeding directly against the
Guarantor.

SECTION 5.5 Guarantee of Payment

                  This Preferred Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6 Subrogation

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

SECTION 5.7 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 Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

Section 2.6    Events of Default; Waiver.

               (a) The Holders of not less than a Majority in liquidation amount
of Trust Preferred Securities may, by vote or written consent, on behalf of the
Holders of all of the Trust Preferred Securities, waive any past Event of
Default in respect of the Trust Preferred Securities and its consequences,
provided that, if the corresponding Debenture Event of Default or Other Document
Event of Default:

                   (i) is not waivable under the Debentures or any Other
        Document, if any, as the case may be, the Event of Default under this
        Agreement shall also not be waivable; or

                   (ii) requires the consent or vote of greater than a majority
        in principal amount of the holders of the Debentures or more than a
        majority of other interests in such Other Document, as the case may be
        (a "Super Majority"), to be waived under the Indenture or such Other
        Document, as the case may be, the Event of Default under this Agreement
        may only be waived by the vote of the relevant Super Majority in
        liquidation amount of Holders of the Trust Preferred Securities.

The foregoing provisions of this Section 2.6(a) shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Agreement and the
Trust Securities, as permitted by the Trust Indenture Act. Upon such waiver, any
such Debenture Event of Default or Other Document Event of Default shall cease
to exist, and any Event of Default with respect to the Trust Preferred
Securities arising therefrom shall be deemed to have been cured, for every
purpose of this Agreement, but no such waiver shall extend to any subsequent or
other default or Event of Default with respect to the Trust Preferred Securities
or impair any right consequent thereon. Any waiver by the Holders of the Trust
Preferred Securities of an Event of Default with respect to the Trust 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 Agreement without any further act, vote, or
consent of the Holders of the Common Securities.

               The Holders of a Majority in liquidation amount of the Trust
Preferred Securities shall 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, including the right to direct the Property Trustee to exercise the
remedies available to it as a holder of the Debentures and any Other Documents;
provided, however, that (subject to the provisions of Section 3.9) the Property
Trustee shall have the right to decline to follow any such direction if the
Property Trustee shall determine that the action so


                                       10
<PAGE>   18

directed would be unjustly prejudicial to the Holders not taking part in such
direction or if the Property Trustee, being advised by competent legal counsel,
determines that the action or proceeding so directed may not lawfully be taken
or if the Property Trustee, in good faith, by its board of directors or
trustees, executive committee, or a trust committee of directors or trustees,
and/or Responsible Officers, shall determine that the action or proceeding so
directed would involve the Property Trustee in personal liability.

               (b) The Holders of a Majority in liquidation amount of the Common
Securities may, by vote or consent, 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 Debentures or Other Document,
        except where the Holders of the Common Securities are deemed to have
        waived such Event of Default under this Agreement as provided elsewhere
        in this Section 2.6, the Event of Default under this Agreement 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 Agreement as provided below
        in this Section 2.6, such Event of Default under this Agreement may only
        be waived by the vote or consent 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, notwithstanding (i) or (ii) above, each Holder of the
Common Securities shall be deemed to have waived any such Event of Default and
all Events of Default with respect to the Common Securities and its consequences
if all Events of Default with respect to the Trust 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 Trust Preferred
Securities and only the Holders of the Trust 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 2.6(b) shall be in lieu of
Sections 316(a)(1)(A) and 316 (a)(1)(B) and of the Trust Indenture Act and such
Sections 316(a)(1)(A) and 316 (a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Agreement and the Securities, as permitted by the
Trust Indenture Act. Subject to the foregoing provisions of this Section 2.6(b),
upon such waiver, any such Debenture Event of Default or Other Document Event of
Default shall cease to exist, and any Event of Default with respect to the
Common Securities arising therefrom shall be deemed to have been cured for every
purpose of this Agreement, 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 a Debenture Event of Default or Other Document
Event of Default by the Property Trustee at the direction of the Holders of the
Trust Preferred Securities constitutes a waiver of the corresponding Event of
Default with respect to the Trust Preferred Securities under this Agreement. Any
waiver of a Debenture Event of Default or Other Document Event of Default by the
Property Trustee at the direction of the Holders of the Trust


                                       11
<PAGE>   19

Preferred Securities shall also be deemed to constitute a waiver by the Holders
of the Common Securities of the corresponding Event of Default under this
Agreement with respect to the Common Securities for all purposes of this
Agreement without further act, vote or consent of the Holders of the Common
Securities. The foregoing provisions of this Section 2.6(c) shall be in lieu of
Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Agreement and the
Securities, as permitted by the Trust Indenture Act.

Section 2.7    Event of Default; Notice.

               (a) The Property Trustee shall, within 90 days after a
Responsible Officer of the Property Trustee obtains actual knowledge of the
occurrence of a default, transmit by mail, first class postage prepaid, to the
Holders of the Securities, notices of all defaults known to the Property Trustee
other than defaults that have been cured or waived before the giving of such
notice (the term "defaults" for the purposes of this Section 2.7(a) being hereby
defined to include Debenture Events of Default and Other Document Events of
Default, if any, not including any periods of grace provided for therein and
irrespective of the giving of any notice provided therein); provided that,
except for a default in the payment of principal of (or premium, if any) or
interest on, or in the delivery of any cash, securities or other property in
exchange for or upon conversion or redemption of or otherwise in accordance with
the terms of, any Debenture or Other Document or the Securities, the Property
Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer of the Property Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders of the Securities.

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

               (i) a default under Sections 501(1) and 501(2) of the Indenture;

               (ii) any failure to deliver any cash, securities or other
        property in exchange for or upon conversion or redemption of or
        otherwise in accordance with the terms of the Debentures or Other
        Documents or the Securities; and

               (iii) any default as to which the Property Trustee shall have
        received written notice or of which a Responsible Officer of the
        Property Trustee shall have actual knowledge.

               (c) The Sponsor and the Administrative Trustee shall file
annually within 30 days after May 15 of each year, commencing with the May 15
that first occurs following the issuance of the Securities, with the Property
Trustee in accordance with Section 314(a)(4) of the Trust Indenture Act a

conditions applicable to them under this Agreement.

                                  ORGANIZATION

Section 3.1    Name.

               The Trust is named "Apache Trust [I/II]," as such name may be
modified from time to time by the Administrative Trustees. The Administrative
Trustees shall give prompt written notice of any change in the name of the Trust
to the Delaware Trustee, the Property Trustee and the Holders of the Securities.
The Trust's activities may be conducted under the name of the Trust or any other
name deemed advisable by the Administrative Trustees.

Section 3.2    Office.

               The address of the principal office of the Trust is c/o Apache
Corporation, One Post Oak Central, 2000 Post Oak Boulevard, Suite 100, Houston,
Texas 77056-4400. On ten Business Days prior written notice to the Property
Trustee and Holders of the Securities, the Administrative Trustees may designate
another principal office.

Section 3.3    Purposes.

               The exclusive purposes and functions of the Trust are (a) to
issue and sell the Securities and use the gross proceeds from such sale to
acquire the Debentures and any Other Documents specified in the Terms and
Conditions, (b) to enter into or hold each Other Document, if any, to be entered
into or held by the Trust in accordance with the Terms and Conditions and (c) to
engage in only those other activities necessary or incidental thereto. The Trust
shall not borrow money, issue debt or reinvest proceeds derived from
investments, pledge any of its assets, execute mortgages or otherwise undertake
(or permit to be undertaken) any activity that would cause the Trust not to be
classified for United States federal income tax purposes as a grantor trust. It
is the intent of the parties to this Agreement for the Trust to be classified as
a grantor trust for United States federal income tax purposes under Subpart E of
Subchapter J of the Code, pursuant to which the owners of the Trust Preferred
Securities and the Common Securities will be the owners of the Trust for United
States federal income tax purposes, and such owners will include directly in
their gross income the income, gain, deduction or loss of the Trust as if the
Trust did not exist. By the acceptance of this Agreement neither the Trustees
nor the Sponsor or the Holders of the Trust Preferred Securities or Common
Securities will take any position for United States federal income tax purposes,
or permit the Trust to make any election, which is contrary to the
classification of the Trust as a grantor trust.

Section 3.4    Authority.

               Subject to the limitations provided in this Agreement and to the
specific duties of the Property Trustee, the Administrative Trustees shall have
exclusive and complete authority to carry out the purposes of the Trust. An
action taken by the Administrative Trustees in accordance with their powers
shall constitute the act of and serve to bind the Trust and an action taken by
the Property Trustee on behalf of the Trust in accordance with its powers shall
constitute the act of and serve to bind the Trust. In dealing with the Trustees
acting on behalf of the Trust, no Person shall be required to inquire into the
authority of the Trustees to bind the


                                       13
<PAGE>   21

Trust. Persons dealing with the Trust are entitled to rely conclusively on the
power and authority of the Trustees as set forth in this Agreement.

Section 3.5 Title to Property of the Trust.

               Except as provided in Section 3.8 with respect to the Trust
Property and the Property Trustee Account or as otherwise provided in this
Agreement, legal title to all assets of the Trust shall be vested in the Trust.
A Holder shall not have legal title to any part of the assets of the Trust, but
shall have an undivided beneficial interest in the assets of the Trust.

Section 3.6    Powers and Duties of the Administrative Trustees.

               The Administrative Trustees shall have the power, duty and
authority, which shall be exclusive except as otherwise set forth herein, and
are hereby authorized and directed to cause the Trust to engage in the following
activities:

               (a) execute, deliver, issue and sell the Trust Preferred
Securities and the Common Securities in accordance with this Agreement;
provided, however, that the Trust may issue no more than one series of Trust
Preferred Securities and no more than one series of Common Securities, and,
provided further, that there shall be no interests in the Trust other than the
Securities, and the issuance of Securities shall be limited to a simultaneous

        placement of a lien on any Trust Property;

               (viii) issue any securities or other evidences of beneficial
        ownership of, or beneficial interest in, the Trust other than the

        amount with respect to the Securities or, where a consent under the
        Indenture or Other Document, as the case may be, would require the
        consent of each holder of Debentures or other interests, as the case may
        be, affected thereby, of each Holder of Securities, and (y) unless the
        Trust shall have received an opinion of nationally recognized

Section 3.8    Powers and Duties of the Property Trustee.

               (a) The legal title to the Trust Property shall be owned by and
held of record in the name of the Property Trustee in trust for the benefit of
the Trust and the Holders of the Securities. The right, title and interest of
the Property Trustee to the Trust Property shall vest automatically in each
Person who may hereafter be appointed as Property Trustee in accordance with
Section 5.6. Such vesting and cessation of title shall be effective whether or
not conveyancing documents with regard to the Trust Property have been executed
and delivered.

               (b) The Property Trustee shall not transfer its right, title and
interest in the Trust Property to the Administrative Trustees or to the Delaware
Trustee (if the Property Trustee does not also act as Delaware Trustee) or,
except in accordance with the provisions of this Agreement and the Securities,
any other Person.

               (c) The Property Trustee shall:

                   (i) establish and maintain one or more segregated
        non-interest bearing trust accounts (collectively, the "Property Trustee
        Account") in the name of and under the exclusive control of the Property
        Trustee on behalf of the Trust and the Holders and, upon the receipt of
        funds in respect of the Trust Property, deposit such funds into the
        Property Trust Account and, upon the receipt of funds distributed to the
        Property Trustee in respect of the Trust Property held by the Property
        Trustee, deposit such funds into the Property Trustee Account, and make
        distributions of such funds out of the Property Trust Account to the
        Holders of the Trust Preferred Securities and the Holders of the Common
        Securities in accordance with the terms of this Agreement and the
        Securities. Funds in the Property Trustee Account shall be held
        uninvested until disbursed in accordance with this Agreement and the
        Securities. The Property Trustee Account shall be one or more accounts
        maintained with one or more banking institutions (which may include the
        Property Trustee if it qualifies hereunder) the rating on whose
        long-term unsecured indebtedness is rated at least "A" or above by a
        "nationally recognized statistical rating organization," as that term is
        defined for purposes of Rule 436(g)(2) under the Securities Act;

                   (ii) upon receipt of any Trust Property on each Closing Date
        and the receipt of any property other than funds distributed to the
        Property Trustee in respect of Trust Property held by the Property
        Trustee, hold such other property in safe keeping and make distributions
        of such other property to the Holders of the Trust Preferred Securities
        and the Holders of the Common Securities in accordance with the terms of
        this Agreement and the Securities; and

                   (iii) engage in such ministerial activities as shall be
        necessary or incidental to hold the Trust Property in accordance with
        the provisions hereof and to effect distributions on and any redemption,
        repayment, conversion or exchange of the Trust Preferred Securities or
        the Common Securities and the distribution of all or any part of the
        Trust Property to Holders in liquidation of the Trust or otherwise, in
        each case in accordance with the terms of this Agreement and the
        Securities.


                                       18
<PAGE>   26

               (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 and this Agreement.

               (e) Subject to Section 3.9(a), the Property Trustee shall take
any Legal Action which arises out of or in connection with an Event of Default
of which a Responsible Officer of the Property Trustee has actual knowledge or
the Property Trustee's duties and obligations under this Agreement, the Business
Trust Act or the Trust Indenture Act; provided, however, that if the Property
Trustee fails to enforce its rights under the Debentures or any Other Document
after a Holder of Trust Preferred Securities has made a written request, such
Holder of Trust Preferred Securities may, to the fullest extent permitted by
applicable law, institute a legal proceeding against the Debenture Issuer or any
obligor under any Other Document, as the case may be, without first instituting
any legal proceeding against the Property Trustee or any other Person.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to (i) the failure of the Debenture
Issuer to pay interest or any premium on or principal of the Debentures on the
date such interest or principal is otherwise payable (including, in the case of
repayment or redemption, on the repayment or redemption date) or, if the
Debentures are exchangeable or convertible, the failure of the Debenture Issuer
to convert or exchange the Debentures into or for other property in accordance
with the terms thereof, or (ii) the failure of any obligor under any Other
Document to pay or deliver cash, securities or other property in accordance with
the terms of such Other Document, then, in the case of (i) and (ii), a Holder of
Trust Preferred Securities may directly institute a proceeding (a "Direct
Action") for enforcement of payment or delivery to such Holder of the principal
of or interest on or other property deliverable upon the exchange or conversion
of Debentures having a principal amount equal to the aggregate liquidation
amount of the Trust Preferred Securities of such holder on or after the due date
specified in the Debentures or any cash, securities or other property that is
required to be paid or delivered pursuant to such Other Document on or after the
due date therefor equal to the percentage of outstanding securities represented
by such Holder's Securities. In connection with such Direct Action, the rights
of the Holders of Common Securities will be subordinated to the rights of such
Holders of Trust Preferred Securities. Except as provided in the preceding
sentences, the Holders of Trust Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures or
Other Documents.

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

                   (i) the Trust has been completely dissolved and wound up and
        the proceeds of the liquidation distributed to the Holders of Securities
        and the Trust is terminated, in accordance with the terms of the
        Securities and this Agreement; or

                   (ii) a successor Property Trustee has been appointed and has
        accepted that appointment in accordance with Section 5.6 (a "Successor
        Property Trustee").

(g) The Property Trustee shall have the legal power to exercise all of the
rights, powers and privileges of the Trust as holder of Debentures under the
Indenture and as beneficiary of or party to any Other Document and, if an Event
of Default actually known to a Responsible Officer of the Property Trustee
occurs and is continuing, the Property Trustee shall,


                                       19
<PAGE>   27

for the benefit of Holders of the Securities, enforce the rights of the Trust as
holder of the Debentures and as beneficiary of or party to any Other Document
subject, in each case, to the rights of the Holders pursuant to the terms of the
Securities and this Agreement.

               (h) The Property Trustee shall be authorized to undertake any
actions set forth in Section 317(a) of the Trust Indenture Act.

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

               (j) For such time as the Property Trustee is the Paying Agent,
the Property Trustee may authorize one or more Persons to act as additional
Paying Agents and to make distributions, redemption payments or liquidation
payments on behalf of the Trust with respect to all Securities. Any such
additional Paying Agent may be removed by the Property Trustee, at any time, so
long as the Property Trustee remains as Paying Agent and a successor Paying
Agent or additional Paying Agents may be (but are not required to be) appointed
at any time by the Property Trustee.

               (k) The Property Trustee must exercise the powers set forth in
this Section 3.8 in a manner that is consistent with the purposes and functions
of the Trust set out in Section 3.3, and the Property Trustee shall not take any
action that is inconsistent with the purposes and functions of the Trust set out
in Section 3.3.

Section 3.9    Certain Duties and Responsibilities of the Property Trustee.

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

               (b) No provision of this Agreement shall be construed to relieve
the Property Trustee from liability for its own negligent action, its own
negligent failure to act, its bad faith 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 Agreement and the Property Trustee shall not be liable
                  except for the performance of such duties and obligations as
                  are specifically set forth in this Agreement, and no implied
                  covenants or obligations shall be read into this Agreement
                  against the Property Trustee; and



                                       20
<PAGE>   28

                           (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 Agreement; provided, 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 Agreement;

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

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

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

                   (v) the Property Trustee's sole duty with respect to the
        custody, safe keeping and physical preservation of the Trust Property
        and the Property Trustee Account shall be to deal with such property in
        a manner that is similar to the manner in which the Property Trustee
        deals with similar property for its fiduciary accounts generally,
        subject to the protections and limitations on liability afforded to the
        Property Trustee under this Agreement, the Business Trust Act and the
        Trust Indenture Act;

                   (vi) the Property Trustee shall have no duty or liability for
        or with respect to the value, genuineness, existence or sufficiency of
        the Trust Property or the payment of any taxes or assessments levied
        thereon or in connection therewith;

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



                                       21
<PAGE>   29

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

               (a) Subject to the provisions of Section 3.9:

                   (i) the Property Trustee may conclusively rely and shall be
        fully protected in acting or refraining from acting upon any resolution,
        certificate, statement, instrument, opinion, report, notice, request,
        direction, consent, order, bond, debenture, note, other evidence of
        indebtedness or other paper or document believed by it to be genuine and
        to have been signed, sent or presented by the proper party or parties;

                   (ii) any direction or act of the Sponsor or the
        Administrative Trustees contemplated by this Agreement shall be
        sufficiently evidenced by a Direction or an Officers' Certificate;

                   (iii) whenever in the administration of this Agreement, the
        Property Trustee shall deem it desirable that a matter be proved or
        established before taking, suffering or omitting any action hereunder,
        the Property Trustee (unless other evidence is herein specifically

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

                   (x) whenever in the administration of this Agreement the

        proportion in liquidation amount of the Securities as would be entitled
        to direct the Property Trustee under the terms of the Securities in
        respect of such remedy, right or action), (B) may refrain from enforcing
        such remedy or right or taking such other action until such instructions
        are received, and (C) shall be protected in conclusively relying on or
        acting in accordance with such instructions, provided that -------- the
        Property Trustee shall not take any action unless it shall have obtained
        the legal opinions required by the applicable provisions of this
        Agreement;

                   (xi) except as otherwise expressly provided by this

jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to

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

                           (B) substitutes for the Trust Preferred Securities
                  other securities having substantially the same terms as the
                  Trust Preferred Securities (the "Successor Trust Preferred
                  Securities"), so long as the Successor Trust Preferred
                  Securities rank the same as the Trust Preferred Securities

                  payments upon liquidation, redemption, repayment and otherwise
                  and substitutes for the Common Securities other securities
                  having substantially the same terms as the Common Securities

                  with respect to distributions of Trust Property and payments
                  upon liquidation, redemption, repayment and otherwise;

        exchange or with another system on which the Trust Preferred Securities
        are then listed, quoted or included for trading;

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

                   (v) such merger, conversion, consolidation, amalgamation or

        material respect;

                   (vi) such Successor Entity has a purpose substantially
        identical to that of the Trust; (vii) prior to such merger, conversion,
        consolidation, amalgamation or replacement, the Sponsor has received an
        opinion of a nationally recognized independent counsel to the Trust
        experienced in such matters to the effect that:

                           (A) such merger, conversion, consolidation,
                  amalgamation or replacement does not adversely affect the
                  rights, preferences and privileges of the Holders of the
                  Securities (including any Successor Securities) in any
                  material respect;

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



                                       25
<PAGE>   33

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

                   (viii) the Sponsor, directly or indirectly, owns all of the
        Successor Common Securities and guarantees the obligations of such
        Successor Entity under the Successor Trust Preferred Securities at least
        to the extent provided by the Securities Guarantees.

                   (ix) the Property Trustee has received an Officers'
        Certificate from the Sponsor and an opinion of counsel, each to the
        effect that all conditions precedent to the transaction as set forth in
        this Agreement have been satisfied.

               (c) Notwithstanding Section 3.14(b), the Trust shall not, except
with the consent of Holders of 100% in liquidation amount of the Securities,
consolidate, amalgamate, merge or convert with or into, or be replaced by any
other Person or permit any other Person to consolidate, amalgamate or merge with
or into, or replace it if such consolidation, amalgamation, merger, conversion,
or replacement would cause the Trust or Successor Entity to be classified as
other than a grantor trust for United States federal income tax purposes.

        Delaware Trustee and delivered to the Trust, the Sponsor, the Property
        Trustee, the resigning Delaware Trustee and, after an Event of Default
        has occurred and is continuing, the Holders of Trust Preferred
        Securities.

               (d) The Holders of the Common Securities or, if an Event of
Default has occurred and is continuing after the issuance of any Securities, the
Holders of Trust Preferred Securities shall use all reasonable efforts to
promptly appoint a Successor Delaware Trustee or Successor Property Trustee, as
the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 5.6.

               (e) If no Successor Property Trustee or Successor Delaware
Trustee shall have been appointed and accepted appointment as provided in this
Section 5.6 within 60 days after delivery to the other Trustees, the Sponsor,
the Trust and, after an Event of Default has occurred and is continuing, the
Holders of the Trust Preferred Securities of an instrument of resignation, the
resigning Property Trustee or Delaware Trustee, as applicable, may petition any
court of competent jurisdiction for appointment of a Successor Property Trustee
or Successor Delaware Trustee. Such court may thereupon, after prescribing such
notice, if any, as it may deem proper, appoint a Successor Property Trustee or
Successor Delaware Trustee, as the case may be.

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

               (g) At the time of the resignation or removal of the Property
Trustee or the Delaware Trustee, the Sponsor shall pay to such Trustee any
amounts that may be owed to such Trustee pursuant to Section 10.4.

Section 5.7    Vacancies Among Trustees.

               If a Trustee ceases to hold office for any reason and the number
of Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees
is increased pursuant to Section 5.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the Administrative Trustees or, if
there are more than two Administrative Trustees, a majority of the
Administrative Trustees shall be conclusive evidence of the existence of such
vacancy. The vacancy shall be filled with a Trustee appointed in accordance with
Section 5.6.

Section 5.8    Effect of Vacancies.

               The death, resignation, retirement, removal, bankruptcy,

Trustee shall not operate to dissolve, terminate or annul the Trust. Whenever a
vacancy among the Administrative Trustees shall occur, until such vacancy is
filled by the appointment of an Administrative Trustee in accordance with
Section 5.6, the Administrative Trustees in office, regardless of their number,
shall have all the powers granted to the Administrative Trustees and shall
discharge all the duties imposed upon the Administrative Trustees by this
Agreement.

Section 5.9    Meetings.

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

Section 5.10   Delegation of Power.

               (a) Any Administrative 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 documents
contemplated in Section 3.6.

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

Section 5.11   Merger, Conversion, Consolidation or Succession to Business.

               Any Person into which the Property Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either may
be consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Property Trustee or the Delaware Trustee, as the case
may be, shall be a party, or any Person succeeding to all or substantially all
the corporate trust business of the Property Trustee or the Delaware Trustee, as
the case may be, shall be the successor of the Property Trustee or the Delaware
Trustee, as the case may be, hereunder, provided 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; provided
however, that such successor shall promptly notify the Sponsor (except that a
Successor Delaware Trustee shall file an appropriate amendment to the
Certificate of Trust of the Trust, if required by the Business Trust Act).

Section 6.1    Distributions.

               If and to the extent that the Trust receives income on any

(including any interest or premium on or the principal of the Debentures, any
securities or other property received in exchange or upon conversion of the
Debentures, or any cash, securities or other property received under any Other
Document), then, unless otherwise specified in this Agreement, the Property
Trustee shall distribute such income, cash, securities and other property to the
Holders of the Securities in accordance with the terms of the Securities they
hold as set forth in this Agreement, including the Terms and Conditions. The
Property Trustee shall make the distributions on the Trust Preferred Securities
and the Common Securities in accordance with the relative rights, preferences
and privileges that apply to each of those classes of Securities as set forth in
this Agreement.

                                  ARTICLE VII.

of the Trust, although at the date of the execution and delivery of the

shall be printed, lithographed or engraved or may be produced in any other
manner as is reasonably acceptable to the Administrative Trustee, as evidenced
by such individual's execution thereof, and may have such letters, numbers or

the Administrative Trustee that signs such Certificates may deem appropriate, or
as may be required to comply with any law or with any rule or regulation of any
stock exchange on which Securities may be listed, or to conform to usage.



                                       36
<PAGE>   44

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

               Each Trust Preferred Security Certificate shall be dated the
date of its authentication by the Property Trustee. Each Common Security
Certificate shall be dated the date it is executed by an Administrative Trustee.

               Upon a written order of the Trust signed by one Administrative
Trustee, the Property Trustee shall authenticate Trust Preferred Security
Certificates, provided the aggregate liquidation amount or number of the Trust
Preferred Securities shall not exceed the aggregate liquidation amount or
number, as the case may be, of Trust Preferred Securities designated in the
Terms and Conditions, as such liquidation amount or number, as the case may be,
may be reduced by redemptions, repayments, exchanges, conversions or liquidating
distributions.

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

               (d) The consideration received by the Trust for 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
Agreement, the Securities so issued shall be deemed to be validly issued, fully
paid and, subject to Section 10.1(b), non-assessable.

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

Section 7.2    Paying Agent and Registrar.

               In the event that the Trust Preferred Securities are not in
book-entry only form:

               (a) The Trust shall maintain in the Borough of Manhattan, The
City of New York, an office or agency where the Trust Preferred Securities may
be presented for payment ("Paying Agent"), and any such Paying Agent shall
comply with Section 317(b) of the Trust Indenture Act. The Administrative
Trustees on behalf of the Trust may appoint the Paying Agent and may appoint one
or more additional paying agents in such other locations as it shall determine.
The term "Paying Agent" includes any additional paying agent. The Administrative
Trustees on behalf of the Trust may change any Paying Agent without prior notice
to any Holder. The Administrative Trustees on behalf of the Trust shall notify
the Property Trustee of the name and address of any Paying Agent not a party to
this Agreement. If the Administrative Trustees on behalf of the Trust fail to
appoint or maintain another entity as Paying Agent, the Property


                                       37
<PAGE>   45

Trustee shall act as such. The Administrative Trustees on behalf of the Trust or
any of its Affiliates (including the Sponsor) may act as Paying Agent. The
Property Trustee at its Corporate Trust Office shall initially act as Paying
Agent for the Trust Preferred Securities and the Common Securities.

               (b) The Trust shall maintain in the Borough of Manhattan, The
City of New York, an office or agency where Trust Preferred Securities may be
presented for registration of transfer or exchange ("Registrar"). The Registrar
shall keep a register of the Trust Preferred Securities and of their transfer or
exchange. The Administrative Trustees on behalf of the Trust may appoint the
Registrar and may appoint one or more co-registrars in such other locations as
it shall determine. The term "Registrar" includes any such additional registrar.
The Administrative Trustees on behalf of the Trust may change any Registrar or
co-registrar without prior notice to any Holder. The Administrative Trustees on
behalf of the Trust shall notify the Property Trustee of the name and address of
any Agent not a party to this Agreement. If the Administrative Trustees on
behalf of the Trust fail to appoint or maintain another entity as Registrar, the
Property Trustee shall act as such. The Trust or any of its Affiliates
(including the Sponsor) may act as Registrar. The Administrative Trustees on
behalf of the Trust shall act as Registrar for the Common Securities.

               (c) Notwithstanding Sections 3.6(b)(vi) and 3.6(l), the Trust
initially appoints the Property Trustee as Registrar for the Trust Preferred
Securities and authorizes it to execute and deliver letters, documents and
instruments with DTC and other Clearing Agencies relating to the Trust Preferred
Securities.

        Property) upon the filing of a certificate of dissolution or its
        equivalent with respect to the Sponsor; or the revocation of the
        Sponsor's charter and the expiration of 90 days after the date of
        revocation without a reinstatement thereof;

                   (ii) upon the entry of a decree of judicial dissolution of

        redemption, repayment, conversion or exchange and the amounts necessary
        for redemption, repayment, conversion or exchange thereof shall have
        been distributed to the Holders in accordance with the terms of this
        Agreement and the Securities;

                   (iv) upon the liquidation of the Trust and the distribution
        to the Holders of all amounts they are required to receive in accordance
        with the terms of this Agreement and the Securities;



                                       38
<PAGE>   46

                   (v) the expiration of the term of the Trust provided in
        Section 3.14 of this Agreement; and

                   (vi) any other event specified in the Terms and Conditions.

               (b) As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a) and upon completion of the winding-up of the
Trust, an Administrative Trustee shall file a certificate of cancellation of the
Certificate of Trust of the Trust with the Secretary of State of the State of
Delaware.

               (c) The provisions of Section 4.4 and Article X shall survive the
termination of the Trust.

                                  ARTICLE IX.
                              TRANSFER OF INTERESTS

Section 9.1    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 Agreement and in the
terms of the Securities. To the fullest extent permitted by law, any transfer or
purported transfer of any Security not made in accordance with this Agreement
shall be null and void.

               (b) Subject to this Article IX and the Terms and Conditions,
Trust Preferred Securities shall be freely transferable.

               (c) Subject to this Article IX, the Sponsor and any Related Party
may only transfer Common Securities 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 grantor trust; and

                   (ii) the Trust would be an Investment Company or the
        transferee would become an Investment Company.

Section 9.2    Transfer or Exchange of Certificates.

               The Registrar shall provide for the registration of Certificates
and of transfers or exchanges of Certificates, which shall be effected without
charge but only upon payment (with such indemnity as the Administrative Trustees
may require) in respect of any tax or other government charges that may be
imposed in relation to it. The Trust will not be required to register or cause
to be registered the transfer of its trust preferred securities after they have
been converted, exchanged, repaid, redeemed or called for redemption. Upon
surrender for registration of transfer or exchange of any Certificate at the
Corporate Trust Office of the Property Trustee, the applicable Registrar shall
cause one or more new Certificates to be issued


                                       39
<PAGE>   47

in the name of the designated transferee or transferees or the party requesting
the exchange, as the case may be. Every Certificate surrendered for registration
of transfer or exchange shall be accompanied by a written instrument of transfer
or exchange in form satisfactory to the applicable Registrar and duly executed
by the Holder or such Holder's attorney duly authorized in writing. Each
Certificate surrendered for registration of transfer or exchange shall be
canceled by the applicable Registrar. A transferee of a Certificate and the
recipient of one or more Certificates issued in exchange for cancelled
Certificates shall be entitled to the rights and subject to the obligations of a
Holder hereunder upon the receipt by such transferee or recipient of a
Certificate or Certificates duly executed by an Administrative Trustee and, in
the case of a Trust Preferred Security Certificate, authenticated by the
Property Trustee. By acceptance of a Certificate, each transferee shall be
deemed to have agreed to be bound by this Agreement.

Section 9.3    Deemed Security Holders.

               The Trustees may treat the Person in whose name any Certificate
shall be registered on the books and records of the Trust as the sole holder of
such Certificate and of the Securities represented by such Certificate for
purposes of receiving Distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities represented by such
Certificate on the part of any Person, whether or not the Trust shall have
actual or other notice thereof.

Section 9.4    Book Entry Interests.

               Unless otherwise specified in the Terms and Conditions, the Trust
Preferred Securities Certificates, on original issuance, shall be issued in the
form of one or more, fully registered, global Trust Preferred Security
Certificates (each a "Global Certificate"), to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Trust. Each such Global Certificate
shall initially be registered on the books and records of the Trust in the name
of Cede & Co., the nominee of DTC, and no Trust Preferred Security Beneficial
Owner will receive a definitive Trust Preferred Security Certificate
representing such Trust Preferred Security Beneficial Owner's interests in any
Global Certificate, except as provided in Section 9.7. Except for the definitive
Trust Preferred Security Certificates issued to the Trust Preferred Security
Beneficial Owners pursuant to Section 9.7 or in accordance with the Terms and
Conditions:

               (a) the provisions of this Section 9.4 shall be in full force and
effect;

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

               (c) to the extent that the provisions of this Section 9.4
conflict with any other provisions of this Agreement other than the Terms and
Conditions, the provisions of this Section 9.4 shall control; and

               (d) the rights of the Trust Preferred Security Beneficial Owners
shall be exercised only through the Clearing Agency and shall be limited to
those established by law and


                                       40
<PAGE>   48

agreements between the Trust Preferred Security Beneficial Owners and the
Clearing Agency and/or the Clearing Agency Participants to receive and transmit
payments and other distributions on the Global Certificates to such Clearing
Agency Participants. DTC will make book entry transfers among the Clearing
Agency Participants; provided, that, solely for the purposes of determining
whether the Holders of the requisite amount of Trust Preferred Securities have
voted on any matter provided for in this Agreement, 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 Trust Preferred Security Beneficial Owners' votes or assigning
the right to vote on any matter to any other Persons either in whole or in part.

Section 9.5    Notices to Clearing Agency.

               Whenever a notice or other communication to the Trust Preferred
Security Holders is required under this Agreement, unless and until definitive
fully registered Trust Preferred Security Certificates shall have been issued to
the Trust Preferred Security Beneficial Owners pursuant to Section 9.7 or
otherwise, the Administrative Trustees shall give all such notices and
communications specified herein to be given to the Trust Preferred Security
Holders to the Clearing Agency, and shall have no notice obligations to the
Trust Preferred Security Beneficial Owners.

Section 9.6    Appointment of Successor Clearing Agency.

               If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Trust Preferred Securities, the
Administrative Trustees may, in their sole discretion, appoint a successor
Clearing Agency with respect to such Trust Preferred Securities.

Section 9.7    Definitive Trust Preferred Security Certificates.

               If:

               (a) a Clearing Agency elects to discontinue its services as
securities depositary with respect to the Trust Preferred Securities and a
successor Clearing Agency is not appointed within 90 days after such
discontinuance pursuant to Section 9.6; or

               (b) the Administrative Trustees elect after consultation with the
Sponsor to terminate the book-entry system through the Clearing Agency with
respect to the Trust Preferred Securities, then:

                   (1) definitive fully registered Trust Preferred Security
               Certificates shall be prepared and executed by the Administrative
               Trustees and authenticated by the Property Trustee on behalf of
               the Trust with respect to such Trust Preferred Securities; and

                   (2) upon surrender of any Global Certificate by the Clearing
               Agency, accompanied by registration instructions, the
               Administrative Trustees shall cause definitive fully registered
               Trust Preferred Securities Certificates to be executed, and the
               Property Trustee shall cause such Trust Preferred Securities
               Certificates to be authenticated and delivered to Trust Preferred
               Security Beneficial Owners in



                                       41
<PAGE>   49

               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, said instructions
               of the Clearing Agency. The definitive fully registered Trust
               Preferred Security Certificates shall be printed, lithographed or
               engraved or may be produced in any other manner as is reasonably
               acceptable to the Administrative Trustees, as evidenced by their
               execution thereof, and may have such letters, numbers or other
               marks of identification or designation and such legends or
               endorsements as the Administrative Trustees and the Property
               Trustee may deem appropriate, or as may be required to comply
               with any law or with any rule or regulation made pursuant thereto
               or with any rule or regulation of any stock exchange on which
               Trust Preferred Securities may be listed, or to conform to usage.

Section 9.8    Mutilated, Destroyed, Lost or Stolen Certificates.

               If:

               (a) any mutilated Certificate shall be surrendered to the
Administrative Trustees, or if the Administrative Trustees shall receive
evidence to their satisfaction of the destruction, loss or theft of any
Certificate; and (b) there shall be delivered to the Administrative Trustees and
the Property Trustee such security or indemnity as may be required by them to
keep each of the Trustees and the Trust harmless, then, in the absence of notice
that such Certificate shall have been acquired by a protected purchaser, any
Administrative Trustee on behalf of the Trust shall execute and deliver, and, in
the case of a Trust Preferred Securities Certificate, the Property Trustee shall
authenticate, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like denomination. In connection
with the issuance of any new Certificate under this Section 9.8, the
Administrative Trustees and the Property Trustee may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith.

        Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

                                   ARTICLE X.
                LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES,
                               TRUSTEES OR OTHERS

Section 10.1   Liability.

               (a) Except as expressly set forth in this Agreement, the
Debentures, any other instrument or agreement, the Securities Guarantees and the
terms of the Securities, the Sponsor shall not be:

                   (i) personally liable for the return of any portion of the
        capital contributions (or any return thereon) of the Holders of the
        Securities, which shall be made solely from assets of the Trust; or



                                       42
<PAGE>   50

                   (ii) required to pay to the Trust or to any Holder of
        Securities any deficit upon dissolution of the Trust or otherwise.

               (b) The Sponsor, as the Debenture Issuer, shall be liable for all
of the debts and obligations of the Trust (other than with respect to the
Securities) to the extent not satisfied out of the Trust's assets.

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

Section 10.2   Exculpation.

               (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Agreement or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or, in
the case of the Property Trustee, negligence), bad faith or willful misconduct
with respect to such acts or omissions.

               (b) An Indemnified Person shall be fully protected in relying in
good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Securities might properly be paid.

Section 10.3   Fiduciary Duty.

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

               (b) Unless otherwise expressly provided herein:

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



                                       43
<PAGE>   51

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

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

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

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

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

Section 10.4   Indemnification.

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

                   (ii) The Sponsor shall indemnify, to the fullest extent
        permitted by law, any Company Indemnified Person who was or is a party
        or is threatened to be made a


                                       44
<PAGE>   52

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

                   (iii) Any indemnification under paragraphs (i) and (ii) of
        this Section 10.4(a) (unless ordered by a court) shall be made by the
        Sponsor only as authorized in the specific case upon a determination
        that indemnification of the Company Indemnified Person is proper in the
        circumstances because he has met the applicable standard of conduct set
        forth in paragraphs (i) and (ii). Such determination shall be made (1)
        by the Administrative Trustees by a majority vote of a Quorum consisting
        of such Administrative Trustees who were not parties to such action,
        suit or proceeding, (2) if such a Quorum is not obtainable, or, even if
        obtainable, if a Quorum of disinterested Administrative Trustees so
        directs, by independent legal counsel in a written opinion, or (3) by
        the Common Security Holder of the Trust.

                   (iv) Expenses (including reasonable attorneys' fees)
        incurred by a Company Indemnified Person in defending a civil, criminal,
        administrative or investigative action, suit or proceeding referred to
        in paragraphs (i) and (ii) of this Section 10.4(a) shall be paid by the
        Sponsor in advance of the final disposition of such action, suit or
        proceeding upon receipt of an undertaking by or on behalf of such
        Company Indemnified Person to repay such amount if it shall ultimately
        be determined that such person is not entitled to be indemnified by the
        Sponsor as authorized in this Section 10.4(a). Notwithstanding the
        foregoing, no advance shall be made by the Sponsor if a determination is
        reasonably and promptly made (i) by the Administrative Trustees by a
        majority vote of a Quorum of disinterested Administrative Trustees, (ii)
        if such a Quorum is not obtainable, or, even if obtainable, if a Quorum
        of disinterested Administrative Trustees so directs, by independent
        legal counsel in a written opinion or (iii) the Common Security Holder
        of the Trust, that, based upon the facts known to the Administrative
        Trustees, independent legal counsel or Common Security Holder at the
        time such determination is made, such person acted in bad faith or in a
        manner that such person did not believe to be in or not opposed to the
        best interests of the Trust, or, with respect to any criminal
        proceeding, that such Company Indemnified Person believed or had
        reasonable cause to believe his conduct was unlawful. In no event shall
        any advance be made in instances where the Administrative Trustees,
        independent legal counsel or Common Security Holder reasonably determine
        that such person deliberately breached such person's duty to the Trust
        or its Common or Trust Preferred Security Holders.

<PAGE>   53

                   (v) The indemnification and advancement of expenses provided
        by, or granted pursuant to, the other paragraphs of this Section 10.4(a)
        shall not be deemed exclusive of any other rights to which those seeking
        indemnification and advancement of expenses may be entitled under any
        agreement, vote of shareholders or disinterested directors of the
        Sponsor or Trust Preferred Security Holders of the Trust or otherwise,
        both as to action in his official capacity and as to action in another
        capacity while holding such office. All rights to indemnification under
        this Section 10.4(a) shall be deemed to be provided by a contract
        between the Sponsor and each Company Indemnified Person who serves in
        such capacity at any time while this Section 10.4(a) is in effect. Any
        repeal or modification of this Section 10.4(a) shall not affect any
        rights or obligations then existing.

                   (vi) The Sponsor or the Trust may purchase and maintain
        insurance on behalf of any person who is or was a Company Indemnified
        Person against any liability asserted against him and incurred by him in
        any such capacity, or arising out of his status as such, whether or not
        the Sponsor would have the power to indemnify him against such liability
        under the provisions of this Section 10.4(a).

                   (vii) For purposes of this Section 10.4(a), references to
        "the Trust" shall include, in addition to the resulting or surviving
        entity, any constituent entity (including any constituent of a
        constituent) absorbed in a consolidation or merger, so that any person
        who is or was a director, trustee, officer or employee of such
        constituent entity, or is or was serving at the request of such
        constituent entity as a director, trustee, officer, employee or agent of
        another entity, shall stand in the same position under the provisions of
        this Section 10.4(a) with respect to the resulting or surviving entity
        as such person would have with respect to such constituent entity if its
        separate existence had continued.

                   (viii) The indemnification and advancement of expenses
        provided by, or granted pursuant to, this Section 10.4(a) shall, unless
        otherwise provided when authorized or ratified, continue as to a person
        who has ceased to be a Company Indemnified Person and shall inure to the
        benefit of the successors, heirs, executors and administrators of such a
        person.

               (b) To the fullest extent permitted by law, the Sponsor agrees to
indemnify each Fiduciary Indemnified Person for, and to hold each Fiduciary
Indemnified Person harmless against, any loss, liability or expense to the
extent incurred without gross negligence (or in the case of the Property
Trustee, pursuant to Section 3.9, negligence), bad faith or willful misconduct
on its part, arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including the costs and
expenses (including reasonable legal fees and expenses) of defending itself
against or investigating any claim or liability in connection with the exercise

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

               (c) The Administrative Trustees on behalf of the Trust shall

Section 11.3   Banking.

               The Administrative Trustees, on behalf of the Trust, shall

Trust; provided however, that all payments for the benefit of holders of
Securities of funds in respect of Trust Property shall be made directly to the
Property Trustee Account and no other funds of the Trust shall be deposited in
the Property Trustee Account. The sole signatories for such accounts shall be
designated by the Administrative Trustees; provided, however, that the Property
Trustee shall designate the signatories for the Property Trustee Account.

Section 11.4   Withholding.

               The Administrative Trustees on behalf of the Trust shall comply
with all withholding requirements under United States federal, state and local
law. The Trust shall request, and the Holders shall provide to the Trust, such
forms or certificates as are necessary to establish an exemption from
withholding with respect to each Holder, and any representations and forms as
shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations. The Administrative
Trustees on behalf of 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 over withholding, Holders shall be limited to an action against the
applicable jurisdiction. If the amount required to be withheld was not withheld
from actual distributions made, the Trust may reduce subsequent distributions by
the amount of such withholding.

the Securities or the rules of any stock exchange on which the Trust Preferred
Securities are listed or admitted for trading. The Administrative Trustees shall

10% in liquidation amount of Securities. Such direction shall be given by
delivering to the Administrative Trustees one or more calls in a writing stating
that the signing Holders of Securities wish to call a meeting and indicating the

        of any stock exchange on which the Trust Preferred Securities are listed
        or admitted for trading, such vote, consent or approval may be given at
        a meeting of the Holders of Securities. Any action that may be taken at
        a meeting of the Holders of Securities may be taken without a meeting
        and without prior notice if a consent in writing setting forth the
        action so taken is signed by the Holders of Securities owning not less

        be necessary to authorize or take such action at a meeting at which all
        Holders of Securities having a right to vote thereon were present and
        voting. Prompt notice of the taking of action without a meeting shall be
        given to the Holders of Securities entitled to vote who have not
        consented in writing. The Administrative Trustees may specify that any
        written ballot submitted to the Holder of Securities for the purpose of
        taking any action without a meeting shall be returned to the Trust
        within the time specified by the Administrative Trustees;

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

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

                   (iv) unless the Business Trust Act, this Agreement, the terms
        of the Securities, the Trust Indenture Act or the listing rules of any
        stock exchange on which the Trust Preferred Securities are then listed
        or trading otherwise provides, the Administrative Trustees, in their
        sole discretion, shall establish all other provisions relating to

        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.

Apache Corporation
2000 Post Oak Blvd., Suite 100
Houston, Texas 77056-4400

Ladies and Gentlemen:

         I am an Attorney for Apache Corporation, a Delaware Corporation (the
"Company"), and am rendering this opinion in my capacity as such in connection
with the registration under the Securities Act of 1933, as amended (the "Act"),
of an aggregate of $1,000,000,000 aggregate initial offering price of (i) the
Company's preferred stock, no par value ("Preferred Stock"), (ii) the Company's
common stock, par value $1.25 per share ("Common Stock"), (iii) the Company's
senior unsecured debt securities (the "Senior Debt Securities"), (iv) the
Company's subordinated debt securities (the "Subordinated Debt Securities"), (v)
the Company's Depositary Shares ("Depositary Shares"), (vi) contracts to
purchase shares of Common Stock (the "Common Stock Purchase Contracts") and
(vii) purchase units of the Company each representing ownership of a Common
Stock Purchase Contract and any Senior Debt Securities, Subordinated Debt
Securities, Preferred Stock, debt obligations of any other person, or any
combination thereof ("Common Stock Purchase Units") (viii) preferred securities
(the "Trust Preferred Securities") of Apache Trust I and Apache Trust II, each a
statutory business trust created under the laws of the State of Delaware (the
"Trusts"), and (ix) the Company's guarantees with respect to the Trust Preferred
Securities (the "Guarantees," and together with the Preferred Stock, the Common
Stock, the Senior Debt Securities, the Subordinated Debt Securities, the
Depositary Shares, the Common Stock Purchase Contracts, Common Stock Purchase
Units and the Trust Preferred Securities, the "Securities") described in the
registration statement on Form S-3 (the "Registration Statement") of the Company
and the Trusts.

         The Securities are to be offered upon the terms and subject to the
conditions set forth in one or more underwriting agreements by and between the
Company and/or the Trusts and the persons named as underwriters therein (each an
"Underwriting Agreement"). The Senior Debt Securities are to be issued in one or
more series pursuant to an Indenture between the Company and The Chase Manhattan
Bank, Trustee. The Subordinated Debt Securities are to be issued in one or more
series pursuant to a Subordinated Indenture between the Company and The Chase
Manhattan Bank, Trustee. The Guarantees will be issued pursuant one or more
guarantee agreements between the Company and The Chase Manhattan Bank, Trustee
(each, a "Guarantee Agreement" and, collectively, the "Guarantee Agreements").
If so specified in the applicable

<PAGE>   2
March 28, 2000
Page 2


prospectus supplement, the Preferred Stock may be represented by depositary
shares entitling the holders proportionally to all rights and preferences of the
Preferred Stock.

         Capitalized terms used but not otherwise defined herein shall have the
meanings assigned to them in the Registration Statement.

         In connection herewith, I have examined the Registration Statement
covering the Securities which is to be filed with the Securities and Exchange
Commission, originals or copies certified or otherwise identified to my
satisfaction of the restated certificate of incorporation and the by-laws of the
Company, each as amended to date, the corporate proceedings with respect to the
offering of the Securities and such other documents and instruments as I have
deemed it necessary or appropriate for the expression of the opinions contained
herein.

         I have assumed the authenticity and completeness of all records,
certificates and other instruments presented to be originals, the conformity to
original documents of all records, certificates, and other instruments submitted
to me as copies, the authenticity and completeness of the originals of those
records, certificates and other instruments submitted to me as copies and the
correctness of all statements of fact contained in all records, certificates and
other instruments that I have examined.

         Based on the foregoing, and having regard for such legal considerations
as I have deemed relevant, I am of the opinion that:

1. The Senior Debt Securities, when duly authorized and duly executed by the
proper officers of the Company, authenticated and delivered by the Trustee in
accordance with the Senior Indenture, and issued and sold pursuant to the terms
of the Underwriting Agreement against payment of the consideration therefor,
will constitute valid and legally binding obligations of the Company enforceable
in accordance with their terms.

2. The Subordinated Debt Securities, when duly authorized and duly executed by
the proper officers of the Company, authenticated and delivered by the Trustee
in accordance with the Subordinated Indenture, and issued and sold pursuant to
the terms of the Underwriting Agreement against payment of the consideration
therefor, will constitute valid and legally binding obligations of the Company
enforceable in accordance with their terms.

3. The Preferred Stock and the Common Stock proposed to be issued, when duly
authorized, issued and delivered against payment therefor in accordance with the
terms of the Underwriting Agreement, will be validly issued, fully paid and
non-assessable.

4. Assuming that a deposit agreement relating to the Depositary Shares (the
"Deposit Agreement") has been duly authorized, and when (i) the Registration
Statement has become effective under the Act, (ii) the Deposit Agreement has
been duly executed and delivered, (iii) the terms of the Depositary Shares and
of their issuance and sale have been duly established in conformity with the
Deposit Agreement relating to such Depositary Shares so as not to violate any
applicable law or result in a default under or breach of any agreement or
instrument binding

<PAGE>   3
March 28, 2000
Page 3


upon the Company and so as to comply with any requirement or restriction imposed
by any court or governmental or regulatory body having jurisdiction over the
Company, (iv) the Preferred Stock has been duly and properly authorized for
issuance, (v) such shares of Preferred Stock have been duly issued and paid for
in the manner contemplated in the Registration Statement and any prospectus
supplement relating thereto, and (vi) receipts evidencing the Depositary Shares
are duly issued against the deposit of the Preferred Stock in accordance with
the Deposit Agreement, such Depositary Shares will be legally issued, fully paid
and non-assessable.

5. Assuming that a purchase contract agreement relating to the Common Stock
Purchase Contracts (the "Purchase Contract Agreement") and such Common Stock
Purchase Contracts have been duly authorized, and when (i) the Registration
Statement has become effective under the Act, (ii) the Purchase Contract
Agreement has been duly executed and delivered, (iii) the terms of the Common
Stock Purchase Contracts and of their issuance and sale have been duly
established in conformity with the Purchase Contract Agreement so as not to
violate any applicable law or result in a default under or breach of any
agreement or instrument binding upon the Company and so as to comply with any
requirement or restriction imposed by any court or governmental or regulatory
body having jurisdiction over the Company, and (iv) the Common Stock Purchase
Contracts have been duly executed and issued in accordance with the Purchase
Contract Agreement relating to such Common Stock Purchase Contracts and issued
and sold in the form and in the manner contemplated in the Registration
Statement and any prospectus supplement relating thereto, such Common Stock
Purchase Contracts will constitute valid and binding obligations of the Company,
enforceable in accordance with their terms.

6. Assuming that a Purchase Contract Agreement relating to the Common Stock
Purchase Contracts comprising a part of the Common Stock Purchase Units and such
Common Stock Purchase Contracts have been duly authorized, and when (i) the
Registration Statement has become effective under the Act, (ii) the Purchase
Contract Agreement has been duly executed and delivered, (iii) the terms of the
Common Stock Purchase Contracts and of their issuance and sale have been duly
established in conformity with the Purchase Contract Agreement so as not to
violate any applicable law or result in a default under or breach of any
agreement or instrument binding upon the Company and so as to comply with any
requirement or restriction imposed by any court or governmental or regulatory
body having jurisdiction over the Company, (iv) the terms of the collateral
arrangements relating to such Common Stock Purchase Units have been duly
established and the agreement(s) relating thereto has been duly executed and
delivered, in each case so as not to violate any applicable law or result in a
default under or breach of any agreement or instrument binding upon the Company
and so as to comply with any requirement or restriction imposed by any court or
governmental or regulatory body having jurisdiction over the Company, and the
collateral has been deposited with the collateral agent in accordance with such
arrangements, and (v) the Common Stock Purchase Contracts have been duly
executed and issued in accordance with the Purchase Contract Agreement relating
to such Common Stock Purchase Contracts, and issued and sold in the form and in
the manner contemplated in the Registration Statement and any prospectus
supplement relating thereto, such Common Stock Purchase Units will constitute
valid and binding obligations of the Company, enforceable in accordance with
their terms.

7. With respect to the Guarantees to be issued pursuant to the applicable
Guarantee Agreement, when (i) such Guarantee Agreement has been duly authorized,
validly executed and delivered by each of the parties thereto and (ii) such
Guarantee Agreement has been duly qualified under the Trust Indenture Act of
1939, as amended, the Guarantees will constitute legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their terms.

         The opinions expressed in paragraphs (1), (2), (5), (6) and (7) above
regarding the enforceability of the Senior Debt Securities, the Subordinated
Debt Securities, the Common Stock Purchase Contracts, the Common Stock Purchase
Units and the Guarantees, respectively, are each subject to the exception of the
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other laws relating to or affecting enforcement of creditors
right's generally or by general equity principals, and except further as
enforcement thereof may be limited by (i) requirements that claims with respect
to any Senior Debt Securities, Subordinated Debt Securities, Common Stock
Purchase Contracts, Common Stock Purchase Units or the Guarantees denominated
other than in U. S. Dollars (or a foreign currency or composite currency in
respect of such claim) be converted into U.S. Dollars at a rate of exchange
prevailing on a date determined pursuant to applicable law or (ii) governmental
authority to limit, delay or prohibit the making of payments outside the United
States.

         The opinions set forth above are limited in all respects to matters of
Texas law and to the Delaware General Corporation Law (including the applicable
provisions of the Delaware Constitution and the reported judicial decisions
interpreting these laws).

         I consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of my name under the caption "Legal
Matters" in the Prospectus included as part of the Registration Statement. In
giving such consent, I do not admit That I am in the category of persons whose
consent is required under Section 7 of the Securities Act of 1933, as amended.


                                            Very truly yours,

                  Re:      Apache Trust I

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for Apache
Corporation, a Delaware corporation (the "Company"), and Apache Trust I, a
Delaware business trust (the "Trust"), in connection with the matters set forth
herein. At your request, this opinion is being furnished to you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a)      The Certificate of Trust of the Trust, dated as of
March 13, 2000 (the "Certificate"), as filed in the office of the Secretary of
State of the State of Delaware (the "Secretary of State") on March 13, 2000;

                  (b)      The Trust Agreement of the Trust, dated as of March
13, 2000, among the Company and the trustees of the Trust named therein;

                  (c)      The Registration Statement (the "Registration
Statement") on Form S-3, including a preliminary prospectus (the "Prospectus"),
relating to the undivided beneficial interests in the assets of the Trust (each,
a "Trust Preferred Security" and collectively, the "Trust

<PAGE>   2

Apache Trust I
March 28, 2000

Preferred Securities"), as proposed to be filed by the Company, the Trust and
others with the Securities and Exchange Commission on or about March 28, 2000;

                  (d)      A form of Amended and Restated Trust Agreement of the
Trust (excluding exhibits) (the "Trust Agreement"), to be entered into among the
Company, the trustees of the Trust named therein, and the holders, from time to
time, of undivided beneficial interests in the assets of the Trust, filed as an
exhibit to the Registration Statement; and

                  (e)      A Certificate of Good Standing for the Trust, dated
March 28, 2000, obtained from the Secretary of State.

                  Initially capitalized terms used herein and not otherwise
defined are used as defined in the Trust Agreement.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Trust Agreement constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Trust Agreement and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, that each of the parties to the
documents examined by us has been duly created, organized or formed, as the case
may be, and is validly existing in good standing under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are signatories to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and

<PAGE>   3

Apache Trust I
March 28, 2000
Page 3


authority to execute and deliver, and to perform its obligations under, such
documents, (v) that each party to the documents examined by us has duly
authorized, executed and delivered such documents, (vi) the receipt by each
Person to whom a Trust Preferred Security is to be issued by the Trust
(collectively, the "Trust Preferred Security Holders") of Trust Preferred
Security Certificate for such Trust Preferred Security in the name of such
Person and the payment for the Trust Preferred Security acquired by it, in
accordance with the Trust Agreement and the Registration Statement, and (vii)
that the Trust Preferred Securities are issued and sold to the Trust Preferred
Security Holders in accordance with the Trust Agreement and the Registration
Statement. We have not participated in the preparation of the Registration
Statement and assume no responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1.       The Trust has been duly created and is validly
existing in good standing as a business trust under the Business Trust Act.

                  2.       The Trust Preferred Securities will represent valid
and, subject to the qualifications set forth in paragraph 3 below, fully paid
and nonassessable undivided beneficial interests in the assets of the Trust.

                  3.       The Trust Preferred Security Holders, as beneficial
owners of the Trust, will be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware. We note that the
Trust Preferred Security Holders may be obligated to make payments as set forth
in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Legal
Matters" in the Prospectus. In giving the foregoing consents, we do not thereby
admit that we come within the category of Persons whose consent is

required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Securities and Exchange Commission thereunder. Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.

                                Very truly yours,

documents examined by us has been duly created, organized or formed, as the case
may be, and is validly existing in good standing under the laws of the

authority to execute and deliver, and to perform its obligations under, such

authorized, executed and delivered such documents, (vi) the receipt by each
Person to whom a Trust Preferred Security is to be issued by the Trust
(collectively, the "Trust Preferred Security Holders") of Trust Preferred
Security Certificate for such Trust Preferred Security in the name of such
Person and the payment for the Trust Preferred Security acquired by it, in
accordance with the Trust Agreement and the Registration Statement, and (vii)
that the Trust Preferred Securities are issued and sold to the Trust Preferred
Security Holders in accordance with the Trust Agreement and the Registration

Statement and assume no responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1.       The Trust has been duly created and is validly
existing in good standing as a business trust under the Business Trust Act.

                  2.       The Trust Preferred Securities will represent valid
and, subject to the qualifications set forth in paragraph 3 below, fully paid
and nonassessable undivided beneficial interests in the assets of the Trust.

                  3.       The Trust Preferred Security Holders, as beneficial
owners of the Trust, will be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware. We note that the
Trust Preferred Security Holders may be obligated to make payments as set forth
in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Legal
Matters" in the Prospectus. In giving the foregoing consents, we do not thereby
admit that we come within the category of Persons whose consent is
