                          KEY PRODUCTION COMPANY, INC.

     Key Production is a Delaware corporation formed in 1988.  We are an
independent natural gas and crude oil exploration and production company with
operations in the Anadarko Basin of Oklahoma, the Hardeman Basin of north-
central Texas, the Sacramento Basin of northern California, the Gulf Coast of
Texas, Louisiana and Mississippi and the Rocky Mountains.  Key is headquartered
in Denver, Colorado with regional exploration offices located in Tulsa,
Oklahoma; New Orleans, Louisiana; and Sacramento, California.  We hold interests
in some of our oil and gas properties through our wholly-owned subsidiaries,
Brock Exploration Corporation, Brock Oil & Gas Corporation and Brock Gas Systems
and Equipment, Inc.

                    RATIOS OF EARNINGS TO FIXED CHARGES AND
                RATIOS OF EARNINGS TO COMBINED FIXED CHARGES AND
                           PREFERRED STOCK DIVIDENDS

     Our ratios of earnings to fixed charges and our ratios of earnings to
combined fixed charges and preferred stock dividends were the same for each of
the periods indicated in the table below.  This is because there were no shares
of preferred stock outstanding during any of these periods.

     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

                                      -4-

     -  "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, or, in the case of our ratios of earnings to combined fixed
        charges and preferred stock dividends, those fixed charges plus
        preferred stock dividends.

                                USE OF PROCEEDS

     Unless otherwise indicated in an accompanying prospectus supplement, we
expect to use the net proceeds from the sale of the 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 SECURITIES WE MAY OFFER

     The descriptions of the securities contained in this prospectus, together
with the applicable prospectus supplements, summarize all the material terms and
provisions of the various types of securities that we may offer. The particular
terms of the securities offered by any prospectus supplement will be described
in that prospectus supplement. If indicated in the applicable prospectus
supplement, the terms of the securities may differ from the terms summarized
below. The prospectus supplement will also contain information, where
applicable, about material U.S. federal income tax considerations relating to
the securities, and the securities exchange, if any, on which the securities
will be listed.

     We may sell from time to time, in one or more offerings:

     - common stock;

     - preferred stock; and/or

     - debt securities.

     In this prospectus, we will refer to the common stock, preferred stock, and
debt securities collectively as "securities." The total dollar amount of all
securities that we may issue under this prospectus will not exceed $150,000,000.

     If we issue debt securities at a discount from their original stated
principal amount, then, for purposes of calculating the total dollar amount of
all securities issued under this prospectus, we will treat the initial offering
price of the debt securities as the total original principal amount of the debt
securities.

     This prospectus may not be used to sell securities unless it is accompanied
by a prospectus supplement.

                          DESCRIPTION OF CAPITAL STOCK

     The following description of our common stock and preferred stock, together
with the additional information included in any applicable prospectus
supplements, summarizes the material terms and provisions of these types of
securities. For the complete terms of our common stock, please refer to our
certificate of incorporation and bylaws 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 certificate of incorporation, our authorized capital stock
consists of 50,000,000 shares of common stock, $.25 par value per share.  Key is
not currently authorized to issue preferred shares.  Authority to issue
preferred shares would require a majority vote of Key's stockholders at either
the Annual Meeting of Stockholders or at a Special Meeting called for the
purpose of voting on the authorization of preferred shares. 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 March 31, 1999, Key had 50,000,000 shares of common stock authorized
and 11,524,681 shares of common stock outstanding.  All outstanding shares of
common stock are 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 Key. Our common stock does not have cumulative voting rights. As a
result, subject to the voting rights of any future holders of 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 Key that are legally available to pay
dividends. However, this dividend right is subject to any preferential dividend
rights we may grant to future holders of preferred stock.

 Liquidation

     If Key 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 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 Key. Our articles of incorporation and bylaws do
not restrict the ability of a holder of common stock to transfer his or her
shares of common stock.

                                      -6-
<PAGE>

     When we issue shares of common stock, the shares will be fully paid and
non-assessable. Delaware law provides that, if we make a distribution to our
stockholders other than a distribution of our capital stock, when we are
insolvent, or that renders us 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.

  Listing

     Our common stock is listed on the New York Stock Exchange.

  Transfer Agent and Registrar

     The transfer agent and registrar for our common stock is Continental Stock
Transfer & Trust Company.

PREFERRED STOCK

  General

     Key is not currently authorized to issue preferred shares.  Authority to
issue preferred shares would require a majority vote of Key's stockholders at
either the Annual Meeting of Stockholders or at a Special Meeting called for the
purpose of voting on the authorization of preferred shares.

     If approved by our stockholders, our board of directors will be authorized
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.

  Undesignated Preferred Stock

     This summary of the undesignated preferred stock discusses terms and
conditions that we expect will apply to all series of the preferred stock
offered under this prospectus. The applicable prospectus supplement will
describe the particular terms of each particular series of preferred stock
offered. If indicated in the prospectus supplement, the terms of any series may
differ from the terms described below.

     The following description, together with the applicable prospectus
supplements, will summarize 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 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.  We urge you to read this
certificate of designation.

     We expect the prospectus supplement to 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
        preference per share and the offering price of the preferred stock;

     -  the dividend rate or rates of the shares, the dates at which dividends,
        if declared, will be payable, and whether or not the dividends are to be

                                      -7-
<PAGE>

        cumulative and, if cumulative, the date or dates from which dividends
        shall be cumulative;

     -  the amounts payable on shares of the preferred stock in the event of our
        voluntary or involuntary liquidation, dissolution or winding up;

     -  the redemption rights and price or prices, if any, for the shares of
        preferred stock;

     -  any terms, and the amount, of any sinking fund or analogous fund
        providing for the purchase or redemption of the shares of preferred
        stock;

     -  any restrictions on our ability to make payments on any of our capital
        stock if dividend or other payments are not made on the preferred stock;

     -  any voting rights granted to the holders of the shares of preferred
        stock in addition to those required by Delaware law or our certificate
        of incorporation;

     -  whether the shares of preferred stock will be convertible into shares of
        our common stock or any other class of our capital stock, and, if
        convertible, the conversion price or prices, and any adjustment or other
        terms and conditions upon which the conversion shall be made;

     -  any other rights, preferences, restrictions, limitations or conditions
        relative to the shares of preferred stock permitted by Delaware law or
        our certificate of incorporation;

     -  any listing of the preferred stock on any securities exchange; and

     -  the federal income tax considerations applicable to the preferred stock.

     Subject to our certificate of incorporation 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.

  Anti-Takeover Effect of 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

                                      -8-
<PAGE>

     -  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 Key.

                         DESCRIPTION OF DEBT SECURITIES

     The debt securities will be direct unsecured obligations of Key and may be
senior debt securities, senior subordinated debt securities or junior
subordinated debt securities.

     The debt securities will be issued under one or more indentures in the form
that has been filed as an exhibit to the registration statement of which this
prospectus is a part.  The indentures will be subject to and governed by the
Trust Indenture Act of 1939.

     Key may issue the debt securities in one or more series. Specific terms of
each series of debt securities will be contained in resolutions of Key's board
of directors or in a supplemental indenture. The specific terms will be
described in a prospectus supplement.

     All debt securities of one series need not be issued at the same time and,
unless otherwise provided in the prospectus supplement, Key may issue additional
debt securities of the series without consent of the holders.

     The specific terms of the debt securities may include any of the following:

     -  the title of the debt securities and whether the debt securities are
        senior debt securities, senior subordinated debt securities or junior
        subordinated debt securities;

     -  the aggregate principal amount of the debt securities and any limit on
        the aggregate principal amount;

     -  the price at which the debt securities will be issued;

     -  any right of the holders to convert the debt securities into stock,
        including the initial conversion price and rate and the conversion
        period and any limitations on the transferability of the stock received
        on conversion;

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

     -  the interest rates, which may be fixed or variable;

     -  the dates from which any interest will accrue, the dates on which the
        interest will be payable, the record dates for the interest payments,
        the persons to whom the interest will be payable, and the manner of
        calculating interest ;

                                      -9-
<PAGE>

     -  any right of Key to extend the dates on which principal or interest
        will be payable;

     -  the places where the principal and any interest will be payable, where
        the debt securities may be surrendered for registration of transfer and
        where notices to Key regarding the debt securities and the indenture may
        be served;

     -  any right of Key to elect to redeem the debt securities, including the
        redemption prices and redemption periods;

     -  any obligation of Key to redeem the debt securities under any sinking
        fund or similar provision or at the option of a holder, including the
        redemption prices and redemption periods;

     -  the events that would cause Key to be in default and the consequences of
        default; and

     -  any discharge and release provisions of the indenture.

     The debt securities may be issued at a discount below their principal
amount and provide for less than the entire principal amount to be payable on
acceleration of the maturity of the debt securities. In that case, all material
U.S. federal income tax, accounting and other considerations applicable to the
securities will be described in the prospectus supplement.

     Except as may be set forth in any prospectus supplement, the debt
securities will not contain any provisions that would limit the ability of Key
to incur debt or that would protect holders of debt securities in the event of a
change of control of Key. The prospectus supplement will contain information
with respect to any changes to the events of default of Key that are described
below.

     Covenants

     The prospectus supplement will describe any material covenants of a series
of debt securities.

     Events of Default, Notice and Waiver

     The prospectus supplement and each indenture will describe the events that
would cause Key to be in default and the consequences of default, including the
following:

     -  failure to pay any interest when due that continues for a period of 30
        days;

     -  failure to pay the principal when due;

     -  breach of any other covenant or warranty of Key in the indenture that
        continues for a period of 90 days after written notice as provided in
        the indenture; and

     -  any other event of default provided in the indenture.

     If an event of default under any indenture occurs and is continuing, then
the trustee or the holders of not less than 25 percent in principal amount of
the debt securities of that series will have the right to declare the principal
amount of all the debt securities of that series to be due and payable
immediately by written notice to Key and to the trustee if given by the holders.
If the debt securities of that

                                     -10-
<PAGE>

series were issued at a discount or are indexed securities, only the portion of
the principal amount specified in the terms of the securities may be declared
due and payable. However, at any time after the declaration of acceleration with
respect to debt securities of the series has been made, but before judgement for
payment of the money due has been obtained by the trustee, the holders of a
majority of the principal amount of outstanding debt securities of the series
may rescind the acceleration if all conditions set forth in the indenture are
met.

     The indentures also will provide that the holders of a majority of the
principal amount of the outstanding debt securities of any series may waive any
past default and its consequences, except a default:

     -  in the payment of the principal or interest or

     -  of a provision contained in the indenture that cannot be amended without
        the consent of the holder of each outstanding debt security affected.

     The indentures will provide for other procedures that may be followed by
holders of debt securities, the trustee of any series of debt securities, or
both, if an event of default occurs.

     Amendment of the Indentures

     Amendments of an indenture are permitted with the consent of the holders of
a majority in principal amount of all outstanding debt securities issued under
the indenture affected by the modification or amendment. However, no amendment
may, without the consent of each holder of debt securities affected:

     -  reduce the amount of debt securities whose holders must consent to an
        amendment, supplement or waiver;

     -  reduce the rate of interest or change the time for payment of interest,
        including default interest, on any debt security;

     -  reduce the principal or change the fixed maturity or alter any
        redemption provision or any obligations of Key to offer to purchase or
        to redeem debt securities;

     -  modify the ranking or priority of the debt securities;

     -  waive a continuing default in the payment of principal or interest; or

     -  make any debt security payable at a different place or in different
        currency, or impair the right of any holder to bring suit.

     The holders of a majority in principal amount of the outstanding debt
securities of each series may, on behalf of all holders, waive compliance by Key
with restrictive covenants of the series.

     Key and the trustee may amend the indenture to, among other things, correct
errors and ambiguities without the consent of any holder of debt securities as
set forth in the indenture and as described in the prospectus supplement.

                                     -11-
<PAGE>

     Subordination

     The prospectus supplement will describe any subordination provisions and
will define the senior debt to which the debt securities may be subordinated and
will set forth the approximate amount of senior debt outstanding as of the end
of Key's most recent fiscal quarter.

     Discharge

     Except as otherwise specified in the prospectus supplement, when (1) all
debt securities of a series have become due and payable or will become due and
payable at their stated maturity within one year, and (2) Key deposits with the
trustee funds to pay all amounts due on the entire outstanding series of debt
securities, then Key will have satisfied the indenture with respect to the
series.

     Except as otherwise specified in the prospectus supplement, the indentures
will provide that Key may elect either (a) to be discharged from any series of
debt securities or (b) to be released from certain obligations with respect to
the debt securities under the indenture, in either case after depositing with
the trustee enough money to pay all amounts due on the debt securities on the
scheduled due dates.

     In addition, Key must have delivered to the trustee an opinion of counsel
that the holders of the debt securities (1) will not recognize income, gain or
loss for U.S. federal income tax purposes as a result of the discharge or
release from obligations and (2) 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 discharge or release had not occurred. After a discharge, the
holders of the debt securities will be able to look only to the trust fund for
payment of principal and interest.

     Payment and Paying Agents

     Unless otherwise specified in the applicable prospectus supplement,
principal and interest will be payable at the corporate trust office of the
trustee, the address of which will be stated in the applicable prospectus
supplement. However, at the option of Key, payment of interest may be made by
check mailed to the address of the person entitled to payment as it appears in
the register for the debt securities or by wire transfer of funds to the person
at an account maintained within the United States.

     All monies paid by Key to a paying agent or a trustee for the payment of
principal or interest that remain unclaimed at the end of two years after the
payment has become due will be repaid to Key, and the holder of the debt
security then may look only to Key for payment.

                             BOOK-ENTRY SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, we will
issue securities, other than common stock, in the form of one or more book-entry
certificates registered in the name of a depositary or a nominee of a
depositary. Unless otherwise specified in the applicable prospectus supplement,
the depositary will be The Depository Trust Company. 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,

                                     -12-
<PAGE>

all references to actions by 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 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 clearance and settlement of securities transactions among
        participants through electronic book-entry, thereby eliminating the
        need for the physical movement of securities certificates.

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

                                     -13-
<PAGE>

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.

     DTC has further advised us that its management is aware that some computer
applications, systems, and the like for processing data that are dependent upon
calendar dates, including dates before, on, and after January 1, 2000, may
encounter "Year 2000 problems." DTC has informed its participants and other
members of the financial community that it has developed and is implementing a
program so that its computer systems, as they relate to the timely payment of
distributions to securityholders, book-entry deliveries, and settlement of
trades within DTC, continue to function appropriately. This program includes a
technical assessment and a remediation plan, each of which is complete.
Additionally, DTC's plan includes a testing phase, which is expected to be
completed within appropriate time frames.

     However, DTC's ability to perform properly its services is also dependent
upon other parties, including issuers and their agents, as well as DTC's direct
and indirect participants and third party vendors from whom DTC licenses
software and hardware, and third party vendors on whom DTC relies for
information or the provision of services, including telecommunication and
electrical utility service providers, among others. DTC has informed its
participants and other members of the financial community that it is contacting
and will continue to contact third party vendors from whom it acquires services
to impress upon them the importance of such services being Year 2000 compliant
and determine the extent of their efforts for Year 2000 remediation -- and, as
appropriate, testing -- of their services. In addition, DTC is in the process of
developing contingency plans that it considers appropriate.

     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

                                     -14-
<PAGE>

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.

     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
        depositary 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 Key, 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

     Any of the securities being offered may be sold in any one or more of the
following ways from time to time:

     -  through agents;

     -  to or through underwriters;

     -  through dealers; and

     -  directly by Key.

     The distribution of the securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, at market
prices prevailing at the time of sale, at prices related to the prevailing
market prices or a negotiated prices.

     Offers to purchase securities may be solicited by agents designated by Key.
Any agent involved in the offer or sale of the securities will be named, and any
commissions payable by Key to the agent will be set forth, in the prospectus
supplement. Unless otherwise indicated in the prospectus supplement, the agent
will be acting on a reasonable best efforts basis for the period of its
appointment. The agent may be deemed to be an underwriter, as that term is
defined in the Securities Act of 1933, of the securities so offered and sold.

     If the securities are sold by means of an underwritten offering, Key will
execute an underwriting agreement with underwriters at the time an agreement for
the sale is reached. In that case, the names of the specific managing
underwriter or underwriters, as well as any other underwriters, the amounts
underwritten and terms of the transaction, including commissions, discounts and
any other compensation of the underwriters and dealers, will be set forth in the
prospectus supplement which will be

                                     -15-
<PAGE>

used by the underwriters to make resales of the securities. The underwriters
will acquire securities for their own accounts and may resell them from time to
time in one or more transactions, including negotiated transactions, at fixed
public offering prices or at varying prices determined by the underwriters at
the time of sale. Securities may be offered to the public either through
underwriting syndicates represented by managing underwriters or directly by one
or more underwriters. Unless indicated in the prospectus supplement, the
underwriting agreement will provide that the obligations of the underwriters are
subject to conditions precedent and that the underwriters will be obligated to
purchase all the securities if any are purchased.

     Key may grant to the underwriters options to purchase additional securities
to cover any over-allotments at the initial public offering price, with
additional underwriting commissions or discounts, as may be set forth in the
prospectus supplement.

     If a dealer is used in the sale of the securities, Key will sell the
securities to the dealer as principal. The dealer may then resell the securities
to the public at varying prices to be determined by the dealer at the time of
resale. The dealer may be deemed to be an underwriter, as the term is defined in
the Securities Act, of the securities so offered and sold. The name of the
dealer and the terms of the transaction will be set forth in the prospectus
supplement.

     Offers to purchase securities may be solicited directly by Key and
securities may be sold by Key directly to institutional investors or others, who
may be deemed to be underwriters within the meaning of the Securities Act with
respect to any resale. The terms of the sales will be described in the
prospectus supplement.

     If described in the prospectus supplement, securities may also be offered
and sold, in connection with a remarketing on their purchase, in accordance with
a redemption or repayment under their terms, or otherwise, by one or more
remarketing firms, acting as principals for their own accounts or as agents for
Key. Any remarketing firm will be identified and its compensation and the terms
of any agreement with Key will be described in the prospectus supplement.
Remarketing firms may be deemed to be underwriters, as that term is defined in
the Securities Act, in connection with the securities remarketed.

     If described in the prospectus supplement, Key may authorize agents and
underwriters to solicit offers by certain institutions to purchase securities
from Key at the public offering price set forth in the prospectus supplement
under delayed delivery contracts providing for payment and delivery on the date
or dates stated in the prospectus supplement. The delayed delivery contracts
will be subject to only those conditions set forth in the prospectus supplement.
A commission indicated in the prospectus supplement will be paid to underwriters
and agents soliciting purchases of securities under delayed delivery contracts
accepted by Key.

     Agents, underwriters, dealers and remarketing firms may be entitled under
agreements with Key to indemnification by Key against certain liabilities,
including liabilities under the Securities Act, or to contribution for payments
that the agents, underwriters, dealers and remarketing firms may be required to
make.

     Each series of securities will be a new issue. Other than the common stock,
which is listed on the New York Stock Exchange, new securities will have no
established trading market. Key may elect to list any series of securities on an
exchange, and in the case of common stock, on any additional exchange, but,
unless otherwise specified in the prospectus supplement, Key will not be
obligated to do so. No assurance can be given as to the liquidity of the trading
market for any of the securities.

                                     -16-
<PAGE>

     Agents, underwriters, dealers and remarketing firms may be customers of,
engage in transactions with, or perform services for, Key and its subsidiaries
in the ordinary course of business.

                                 LEGAL MATTERS

     The validity of the common stock and the preferred stock and the status of
the debt securities as binding obligations of Key will be passed on for Key by
Holme Roberts & Owen LLP, Denver, Colorado.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Key's amended certificate of incorporation provides that Key shall, to the
full extent permitted under the Delaware General Corporation Law, 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. Key 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.

                                     II-1
<PAGE>

     Article 6 of Key's bylaws provides, in substance, that directors, officers,
employees and agents of Key shall be indemnified to the fullest extent permitted
by law, including the Delaware General Corporation Law. Additionally, Article IV
of Key's amended certificate of incorporation eliminates in certain
circumstances the personal liability of directors of Key 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 Key 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 Key agrees to in connection with offerings of the
securities registered by this registration statement.

ITEM 17. UNDERTAKINGS.

1.  Key hereby undertakes:

          (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 Key

                                     II-3
<PAGE>

              pursuant to 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.  Key hereby undertakes that, for purposes of determining any liability
         under the Securities Act of 1933, each filing of Key'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 Key pursuant to the provisions described under Item 15
         above, or otherwise, Key has 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 Key of expenses incurred or paid by a
         director, officer or controlling person of Key in the successful
         defense of any action, suit or proceeding) is asserted against Key by
         such director, officer or controlling person in connection with the
         securities being registered, Key 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.  Key hereby undertakes 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 Registrant
              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.

                                     II-4

     5.  Key hereby undertakes 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.

practicable the most recent list available to it of the names and addresses of
Securityholders.  If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least five Business Days before each semi-annual interest
payment date and at such other times as the Trustee may request in writing a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Securityholders.

Section 2.06. Transfer and Exchange.

     Where a Security is presented to the Registrar or a co-Registrar with a
request to register a transfer, the Registrar shall register the transfer as
requested if the requirements of Section 8-01(1) of the New York Uniform
Commercial Code are met.  Where Securities are presented to the Registrar or a
co-Registrar with a request to exchange them for an equal principal amount of
Securities of other denominations, the Registrar shall make the exchange as
requested if the same requirements are met.  To permit transfers and exchanges,
the Trustee shall authenticate Securities at the Registrar's request.  The
Registrar need not transfer or exchange any Security selected for redemption,
except the unredeemed part thereof if the Security is redeemed in part, or
transfer or exchange any Securities for a period of  15 days before a selection
of Securities to be redeemed.  Any exchange or transfer shall be without charge,
except that the Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto except in
the case of exchanges pursuant to  2.09, 3.06, or 9.05 not involving any
transfer.

     Any Holder of a global Security shall, by acceptance of such global
Security, agree that transfers of beneficial interests in such global Security
may be effected only through a book entry system maintained by the Holder of
such global Security (or its agent), and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry.

Section 2.07. Replacement Securities.

     If the Holder of a Security claims that the Security has been lost,
destroyed, mutilated or wrongfully taken, the Company shall issue and, upon
written request of any Officer of the Company, the Trustee shall authenticate a
replacement Security; provided, however, in the case of a lost, destroyed or
wrongfully taken Security, that the requirements of Section 8-405 of the New
York Uniform Commercial Code are met.  If any such lost, destroyed, mutilated or
wrongfully taken Security shall have matured or shall be about to mature, the
Company may, instead of issuing a substitute Security therefor, pay such
Security without requiring (except in the case of a mutilated Security) the
surrender thereof.  An indemnity bond must be sufficient in the judgment of the
Company and the Trustee to protect the Company, the Trustee or any Agent from
any loss which any of them may suffer if a Security is replaced, including the
acquisition of

                                    - 10 -
<PAGE>

such Security by a bona fide purchaser. The Company or the Trustee may charge
the Holder for expenses in replacing a Security.

Section 2.08. Outstanding Securities.

     Securities outstanding at any time are all Securities authenticated by the
Trustee except for those canceled by it and those described in this Section.  A
Security does not cease to be outstanding because the Company or one of its
Affiliates holds the Security.

     If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

     If, on a redemption date or maturity date, the Paying Agent holds money
sufficient to pay Securities payable on that date, then on and after that date
such Securities cease to be outstanding and interest on them ceases to accrue.

     Subject to the foregoing provisions of this Section, 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.

Section 2.09. Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Securities.  Temporary Securities
shall be substantially in the form of definitive Securities but may have
variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and, upon surrender for
cancellation of the temporary Security, the Company shall execute and the
Trustee shall authenticate definitive Securities in exchange for temporary
Securities.  Until so exchanged, the temporary Securities shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
authenticated and delivered hereunder.

Section 2.10. Cancellation.

     The Company at any time may deliver Securities to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange,
redemption or payment.  The Trustee and no one else shall cancel and destroy, or
retain in accordance with its standard retention policy, all Securities
surrendered for registration or transfer, exchange, redemption, paying or
cancellation.  Unless the Authorizing Resolution so provides, the Company may
not issue new Securities to replace Securities that it has previously paid or
delivered to the Trustee for cancellation.

Section 2.11. Defaulted Interest.

     If the Company defaults in a payment of interest on the Securities, it
shall pay the defaulted interest plus any interest payable on the defaulted
interest to the persons who are Securityholders on a subsequent special record
date.  The Company shall fix such special record date and a payment date which
shall be reasonably satisfactory to the Trustee.  At least 15 days before such
special record date, the Company shall mail to each Securityholder a notice that
states the record date, the payment date and the amount of defaulted interest to
be paid.  On or before the date such notice is mailed, the Company shall deposit
with the Paying Agent money sufficient to pay the amount of defaulted interest
to be so paid.  The Company may pay defaulted interest in any other lawful
manner if, after notice given by the Company to the Trustee of the proposed
payment, such manner of payment shall be deemed practicable by the Trustee.

Section 2.12. Treasury Securities.

     In determining whether the Holders of the required principal amount of
Securities of a Series have concurred in any direction, waiver, consent or
notice, Securities owned by the Company or any of its Subsidiaries shall be
considered as though they are not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which the Trustee actually knows
are so owned shall be so considered.

Section 2.13. CUSIP Numbers.

     The Company in issuing the Securities of any Series may use a "CUSIP"
number, and if so, the Trustee shall use the CUSIP number in notices of
redemption or exchange as a convenience to Holders of such Securities; provided
that no representation is hereby deemed to be made by the Trustee as to the
correctness or accuracy of any such CUSIP number printed in the notice or on
such Securities, and that reliance may be placed only on the other
identification numbers printed on such Securities.  The Company shall promptly
notify the Trustee of any change in any CUSIP number.

Section 2.14. Deposit of Moneys.

     Prior to 11:00 a.m. New York City time on each interest payment date and
maturity date with respect to each Series of Securities, the Company shall have
deposited with the Paying Agent in immediately available funds money sufficient
to make cash payments due on such interest payment date or maturity date, as the
case may be, in a timely manner which permits the Paying Agent to remit payment
to the Holders on such interest payment date or maturity date, as the case may
be.

Section 2.15. Book-Entry Provisions for Global Security.

          (a) Any global Security of a Series initially shall (i) be registered
in the name of the depository who shall be identified in the Authorizing
Resolution or supplemental indenture

                                    - 12 -
<PAGE>

relating to such Securities (the "Depository") or the nominee of such
Depository, (ii) be delivered to the Trustee as custodian for such Depository
and (iii) bear any required legends.

          Members of, or participants in, the Depository ("Agent Members") shall
have no rights under this Indenture with respect to any global Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
global Security, and the Depository may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute owner of the global
Security for all purposes whatsoever.  Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a Holder of any Security.

          (b) Transfers of any global Security shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees.  Interests of beneficial owners in the global Security may be
transferred or exchanged for definitive Securities in accordance with the rules
and procedures of the Depository.  In addition, definitive Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests
in a global Security if (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository for the global Security and a
successor depository is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing and the
Registrar has received a request from the Depository to issue definitive
Securities.

          (c) In connection with any transfer or exchange of a portion of the
beneficial interest in any global Security to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more definitive Securities are to
be issued) reflect on its books and records the date and a decrease in the
principal amount of the global Security in an amount equal to the principal
amount of the beneficial interest in the global Security to be transferred, and
the Company shall execute, and the Trustee shall authenticate and deliver, one
or more definitive Securities of like tenor and amount.

          (d) In connection with the transfer of an entire global Security to
beneficial owners pursuant to paragraph (b), the global Security shall be deemed
to be surrendered to the Trustee for cancellation, and the Company shall
execute, and the Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in exchange for its beneficial interest in
the global Security, an equal aggregate principal amount of definitive
Securities of authorized denominations.

          (e) The Holder of any global Security may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities of such Series.

                                   Redemption

Section 3.01. Notices to Trustee.

     Securities of a Series that are redeemable prior to maturity shall be
redeemable in accordance with their terms and, unless the Authorizing Resolution
or supplemental indenture provides otherwise, in accordance with this Article.

     If the Company wants to redeem Securities pursuant to Paragraph 5 of the
Securities, it shall notify the Trustee in writing of the Redemption Date and
the principal amount of Securities to be redeemed.  Any such notice may be
canceled at any time prior to notice of such redemption being mailed to Holders.
Any such canceled notice shall be void and of no effect.

     If the Company wants to credit any Securities previously redeemed, retired
or acquired against any redemption pursuant to Paragraph 6 of the Securities, it
shall notify the Trustee of the amount of the credit and it shall deliver any
Securities not previously delivered to the Trustee for cancellation with such
notice.

     The Company shall give each notice provided for in this Section 3.01 at
least 30 days before the notice of any such redemption is to be mailed to
Holders (unless a shorter notice shall be satisfactory to the Trustee).

Section 3.02. Selection of Securities to be Redeemed.

     If fewer than all of the Securities of a Series are to be redeemed, the
Trustee shall select the Securities to be redeemed by a method the Trustee
considers fair and appropriate.  The Trustee shall make the selection from
Securities outstanding not previously called for redemption and shall promptly
notify the Company of the serial numbers or other identifying attributes of the
Securities so selected.  The Trustee may select for redemption portions of the
principal of Securities that have denominations larger than the minimum
denomination for the Series. Securities and portions of them it selects shall be
in amounts equal to the minimum denomination for the Series or an integral
multiple thereof.  Provisions of this Indenture that apply to Securities called
for redemption also apply to portions of Securities called for redemption.

Section 3.03. Notice of Redemption.

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail a notice of redemption by first-class mail, postage prepaid,
to each Holder of Securities to be redeemed.

     The notice shall identify the Securities to be redeemed and shall state:

                                    - 14 -
<PAGE>

     (1) the redemption date;

     (2) the redemption price;

     (3) the name and address of the Paying Agent;

     (4) that Securities called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

     (5) that interest on Securities called for redemption ceases to accrue on
and after the redemption date; and

     (6) that the Securities are being redeemed pursuant to the mandatory
redemption or the optional redemption provisions, as applicable.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
shall deliver to the Trustee at least 15 days prior to the date on which notice
of redemption is to be mailed or such shorter period as may be satisfactory to
the Trustee, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

Section 3.04. Effect of Notice of Redemption.

     Once notice of redemption is mailed, Securities called for redemption
become due and payable on the redemption date and at the redemption price as set
forth in the notice of redemption.  Upon surrender to the Paying Agent, such
Securities shall be paid at the redemption price, plus accrued interest to the
redemption date.

Section 3.05. Deposit of Redemption Price.

     On or before the redemption date, the Company shall deposit with the Paying
Agent immediately available funds sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date.

Section 3.06. Securities Redeemed in Part.

     Upon surrender of a Security that is redeemed in part, the Company shall
execute and the Trustee shall authenticate for each Holder a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

Section 4.01. Payment of Securities.

     The Company shall pay the principal of and interest on a Series on the
dates and in the manner provided in the Securities of the Series.  An
installment of principal or interest shall be considered paid on the date it is
due, if on that date the Paying Agent holds money designated for and sufficient
to pay the installment.

     The Company shall pay interest on overdue principal at the rate borne by
the Series; it shall pay interest on overdue installments of interest at the
same rate.

Section 4.02. Maintenance of Office or Agency.

     The Company shall maintain the office or agency required under Section
2.03. The Company shall give prior written notice to the Trustee of the
location, and any change in the location, of such office or 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 address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee.

Section 4.03. Compliance Certificate.

     The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company an Officers' Certificate stating whether or not
the signers know of any Default by the Company in performing any of its
obligations under this Indenture.  If they do know of such a Default, the
certificate shall describe the Default.

Section 4.04. Payment of Taxes; Maintenance of Corporate Existence; Maintenance
              of Properties.

     The Company will:

              (a) cause to be paid and discharged all lawful taxes, assessments
and governmental charges or levies imposed upon the Company and its Restricted
Subsidiaries or upon the income or profits of the Company and its Restricted
Subsidiaries or upon property or any part thereof belonging to the Company and
its Restricted Subsidiaries before the same shall be in default, as well as all
lawful claims for labor, materials and supplies which, if unpaid, might become a
lien or charge upon such property or any part thereof; provided, however, that
the Company shall not be required to cause to be paid or discharged any such
tax, assessment, charge, levy or claim so long as the validity or amount thereof
shall be contested in good faith by appropriate proceedings and the nonpayment
thereof does not, in the judgment of the Company, materially adversely affect
the ability of the Company and the Restricted Subsidiaries to pay all

                                    - 16 -
<PAGE>

obligations under this Indenture when due; and provided further, that the
Company shall not be required to cause to be paid or discharged any such tax,
assessment, charge, levy or claim if, in the judgment of the Company, such
payment shall not be advantageous to the Company in the conduct of its business
and if the failure so to pay or discharge does not, in its judgment, materially
adversely affect the ability of the Company and the Restricted Subsidiaries to
pay all obligations under this Indenture when due;

              (b) cause to be done all things necessary to preserve and keep in
full force and effect the corporate existence of the Company and each of its
Restricted Subsidiaries; provided, however, that nothing in this subsection (b)
shall prevent a consolidation or merger of the Company or any Restricted
Subsidiary not prohibited by the provisions of Article Five or any other
provision or the Authorizing Resolution or supplemental indenture pertaining to
a Series, and the Company need not maintain the corporate existence of an
immaterial Restricted Subsidiary ; and

              (c) at all times keep, maintain and preserve the property of the
Company and the Restricted Subsidiaries in good repair, working order and
condition (reasonable wear and tear excepted) and from time to time make all
needful and proper repairs, renewals, replacements, betterments and improvements
thereto, so that the business carried on in connection therewith may be properly
and advantageously conducted at all times; provided, however, that nothing in
this subsection (c) shall prevent the Company from discontinuing the operation
and maintenance of any such properties if such discontinuance is, in the
judgment of the Company, desirable in the conduct of its business and not
disadvantageous in any material respect to the ability of the Company and the
Restricted Subsidiaries to pay all obligations under this Indenture when due.

Section 5.01. When Company May Merge, Etc.

     The Company shall not consolidate with or merge with or into, any other
corporation, or transfer all or substantially all of its assets to, any entity
unless permitted by law and unless (1) the resulting, surviving or transferee
entity, which shall be a corporation organized and existing under the laws of
the United States or a State thereof, assumes by supplemental indenture, in a
form reasonably satisfactory to the Trustee, all of the obligations of the
Company under the Securities and this Indenture and (2) immediately after giving
effect to, and as a result of, such transaction, no Default or Event of Default
shall have occurred and be continuing. Thereafter such successor corporation or
corporations shall succeed to and be substituted for the Company with the same
effect as if it had been named herein as the "Company" and all such obligations
of the predecessor corporation shall terminate.

proposed transaction an Officers' Certificate to the foregoing effect and an
Opinion of Counsel stating that the proposed transaction and such supplemental
indenture comply with this Indenture.

pertaining to any Series provides for different provisions relating to the
subject matter of this Article Five, the provisions in such Authorizing
Resolution or supplemental indenture shall govern for purposes of such Series.

                             Defaults and Remedies

Section 6.01. Events of Default.

     An "Event of Default" on a Series occurs if, voluntarily or involuntarily,
whether by operation of law or otherwise, any of the following occurs:

              (1) the failure by the Company to pay interest on any Security of
such Series when the same becomes due and payable and the continuance of any
such failure for a period of 30 days;

              (2) the failure by the Company to pay the principal or premium of
any Security of such Series when the same becomes due and payable at maturity,
upon acceleration or otherwise;

              (3) the failure by the Company or any Restricted Subsidiary to
comply in all material respects with any of its agreements or covenants in, or
provisions of, the Securities of such Series, or this Indenture (as they relate
thereto) and such failure continues for the period and after the notice
specified below (except in the case of a default with respect to Article Five
(or any replacement provisions as contemplated by Article Five), which will
constitute an Event of Default with notice but without passage of time);

              (4) the acceleration of any Indebtedness (other than Non-Recourse
Indebtedness) of the Company or any Restricted Subsidiary in an amount of $5
million or more, individually or in the aggregate, and such acceleration does
not cease to exist, or such Indebtedness is not satisfied, in either case within
30 days after such acceleration;

              (5) the failure by the Company or any Restricted Subsidiary to
make any principal or interest payment in an amount of $5 million or more,
individually or in the aggregate, in respect of Indebtedness for borrowed money
(other than Non-Recourse Indebtedness) of the Company or any Restricted
Subsidiary within 30 days of such principal or interest becoming due and payable
(after giving effect to any applicable grace period set forth in the documents
governing such Indebtedness);

                                    - 18 -
<PAGE>

              (6) a final judgment or judgments in an amount of $5 million or
more, individually or in the aggregate, for the payment of money having been
entered by a court or courts of competent jurisdiction against the Company or
any of its Restricted Subsidiaries and such judgment or judgments is not covered
by a policy of insurance, satisfied, stayed, annulled or rescinded within 90
days of being entered;

              (7) the Company or any Restricted Subsidiary that is a Significant
Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

                  (A)  commences a voluntary case,

                  (B) consents to the entry of an order for relief against it in
an involuntary case,

                  (C) consents to the appointment of a Custodian of it or for
all or substantially all of its property, or

                  (D) makes a general assignment (except in the case of a
Restricted Subsidiary, to the Company) for the benefit of its creditors; or

              (8) a court of competent jurisdiction enters an order or decree
under any Bankruptcy Law that:

                  (A) is for relief against the Company or any Restricted
Subsidiary that is a Significant Subsidiary as debtor in an involuntary case,

                  (B) appoints a Custodian of the Company or any Restricted
Subsidiary that is a Significant Subsidiary or a Custodian for all or
substantially all of the property of the Company or any Restricted Subsidiary
that is a Significant Subsidiary, or

                  (C) orders the liquidation of the Company or an Restricted
Subsidiary that is a Significant Subsidiary, and the order or decree remains
unstayed and in effect for 90 days.

     A Default as described in sub-clause (3) above will not be deemed an Event
of Default until the Trustee notifies the Company, or the Holders of at least 25
percent in principal amount of the then outstanding Securities of the applicable
Series notify the Company and the Trustee, of the Default and (except in the
case of a default with respect to Article Five (or any replacement provisions as
contemplated by Article Five)) the Company does not cure the Default within 90
days after receipt of the notice.  The notice must specify the Default, demand
that it be remedied and state that the notice is a "Notice of Default." If such
a Default is cured within such time period, it ceases.

     The term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian or similar official under any Bankruptcy Law.

Section 6.02. Acceleration.

     If an Event of Default (other than an Event of Default with respect to the
Company resulting from sub-clauses (7) or (8) above), shall have occurred and be
continuing under the Indenture, the Trustee by notice to the Company, or the
Holders of at least 25 percent in principal amount of the Securities of the
applicable Series then outstanding by notice to the Company and the Trustee, may
declare all Securities of such Series to be due and payable immediately.  Upon
such declaration of acceleration, the amounts due and payable on the Securities
of such Series will be due and payable immediately.  If an Event of Default with
respect to the Company specified in sub-clauses (7) or (8) above occurs, all
amounts due and payable on the Securities of such Series will ipso facto become
and be immediately due and payable without any declaration, notice or other act
on the part of the Trustee and the Company or any Holder.  The Holders of a
majority in principal amount of the Securities of such Series then outstanding
by written notice to the Trustee and the Company may waive any Default or Event
of Default (other than any Default or Event of Default in payment of principal
or interest) with respect to such Series of Securities under the Indenture.
Holders of a majority in principal amount of the then outstanding Securities of
such Series may rescind an acceleration with respect to such Series and its
consequence (except an acceleration due to nonpayment of principal or interest
on the Securities of such Series) if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived.

     No such rescission shall extend to or shall affect any subsequent Event of
Default, or shall impair any right or power consequent thereon.

Section 6.03. Other Remedies.

     If an Event of Default on a Series occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on the Series or to enforce the performance
of any provision in the Securities or this Indenture applicable to the Series.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.

Section 6.04. Waiver of Existing Defaults.

     Subject to Section 9.02, the Holders of a majority in principal amount of
the outstanding Securities of a Series on behalf of all the Holders of the
Series by notice to the Trustee may waive an existing Default on such Series and
its consequences.  When a Default is waived, it is cured and stops continuing,
and any Event of Default arising therefrom shall be deemed to have been cured;
but no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereon.

Section 6.05. Control by Majority.

     The Holders of a majority in principal amount of the outstanding Securities
of a Series 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 it with respect to such Series.  The Trustee, however, may refuse
to follow any direction (i) that conflicts with law or this Indenture, (ii)
that, subject to Section 7.01, the Trustee determines is unduly prejudicial to
the rights of other Securityholders, or (iii) that would involve the Trustee in
personal liability.

Section 6.06. Limitation on Suits.

     A Securityholder of a Series may not pursue any remedy with respect to this
Indenture or the Series unless:

          (1) the Holder gives to the Trustee written notice of a continuing
Event of Default on the Series;

          (2) the Holders of at least a majority in principal amount of the
outstanding Securities of the Series make a written request to the Trustee to
pursue the remedy;

          (3) such Holder or Holders offer to the Trustee indemnity satisfactory

Holder to receive payment of principal of and interest on the Security, on or

of an express trust against the Company for the whole amount of principal and

allowed in any judicial proceedings relative to the Company, its creditors or
its property, and unless prohibited by applicable law or regulation, may vote on
behalf of the Holders in any election of a Custodian, and shall be entitled and
empowered to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same and any Custodian in
any such judicial proceeding is hereby authorized by each Securityholder to make
such payments to the Trustee.  Nothing herein shall be deemed to authorize the
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder or to authorize
the Trustee to vote in respect of the claim of any Securityholder except as
aforesaid for the election of the Custodian.

     Second:  to Securityholders of the Series for amounts due and unpaid on the
              Series for principal and interest, ratably, without preference or

                                    Trustee

Section 7.01. Duties of Trustee.

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall, prior to the receipt of directions from the Holders of a majority in
principal amount of the Securities, exercise its rights and powers and use the
same degree of care and skill in their exercise as a prudent man would exercise
or use under the circumstances in the conduct of his own affairs.

     (b) Except during the continuance of an Event of Default:

         (1) The Trustee need perform only those duties that are specifically
set forth in this Indenture and no others and no implied covenants or
obligations shall be read into this Indenture against the Trustee.

         (2) In the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of his Indenture.  The Trustee,
however, shall examine the certificates and opinions to determine whether or not
they conform to the requirements of this Indenture but need not confirm or
investigate the accuracy of mathematical calculations or other facts or matters
stated herein.

     (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except
that:

         (1) This paragraph does not limit the effect of paragraph (b) of this
Section.

         (2) The Trustee shall not be liable for any error of judgment made in
good faith by a Trust Officer, unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts.

         (3) The Trustee shall not be liable with respect to any action it
takes or omits to take in good faith in accordance with a direction received by
it pursuant to Section 6.05 or any other direction of the Holders permitted
hereunder.

     (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

                                    - 23 -

     (e) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

     (f) The Trustee shall not be liable for interest on any money received by
it except as the Trustee may agree with the Company.  Money held in trust by the
Trustee need not be segregated from other funds except to the extent required by
law.

     (g) None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties or in the exercise of any of its rights
or powers, if there shall be reasonable grounds for believing that the repayment
of such funds or adequate indemnity against such liability is not reasonably
assured to it.

Section 7.02. Rights of Trustee.

     Subject to Section 7.01:

     (a) The Trustee may rely and shall be protected in acting or refraining
from acting on any document, resolution, certificate, instrument, report, or
direction believed by it to be genuine and to have been signed or presented by
the proper person.  The Trustee need not investigate any fact or matter stated
in the document, resolution, certificate, instrument, report, or direction.

     (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both, which shall conform to
Sections 10.04 and 10.05 hereof and containing such other statements as the
Trustee reasonably deems necessary to perform its duties hereunder.  The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on the Officers' Certificate, Opinion of Counsel or any other direction
of the Company permitted hereunder.

     (c) The Trustee may act through agents and shall not be responsible for the
misconduct or negligence of any agent appointed with due care.

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

     (e) The Trustee may consult with counsel, and the written advice of such
counsel or any Opinion of Counsel as to matters of law shall be full and
complete authorization and protection in respect of any action taken, omitted or
suffered by it hereunder in good faith and in accordance with the advice or
opinion of such counsel.

     (f) Unless otherwise specifically provided in the Indenture, any demand,
request, direction or notice from the Company shall be sufficient if signed by
an Officer of the Company.

                                    - 24 -
<PAGE>

     (g) For all purposes under this Indenture, the Trustee shall not be deemed
to have notice or knowledge of any Event of Default (other than under Section
6.01(1) or 6.01(2)) unless a Trust Officer assigned to and working in the
Trustee's corporate trust office has actual knowledge thereof or unless written
notice of any Event of Default is received by the Trustee at its address
specified in Section 10.02 hereof and such notice references the Securities
generally, the Company or this Indenture.

Section 7.03. Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or its Affiliates
with the same rights it would have if it were not Trustee.  Any Agent may do the
same with like rights.  The Trustee, however, must comply with Sections 7.10 and
7.11.

Section 7.04. Trustee's Disclaimer.

     The Trustee makes no representation as to the validity or adequacy of this
Indenture, the Securities or of any prospectus used to sell the Securities; it
shall not be accountable for the Company's use of the proceeds from the
Securities; it shall not be accountable for any money paid to the Company, or
upon the Company's direction, if made under and in accordance with any provision
of this Indenture; it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee; and it shall not be
responsible for any statement of the Company in this Indenture or in the
Securities other than its certificate of authentication.

Section 7.05. Notice of Defaults.

     If a Default on a Series occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Securityholder of the Series notice of
the Default (which shall specify any uncured Default known to it) within 90 days
after it occurs.  Except in the case of a default in payment of principal of or
interest on a Series, the Trustee may withhold the notice if and so long as the
board of directors of the Trustee, the executive or any trust committee of such
directors and/or responsible officers of the Trustee in good faith determine(s)
that withholding the notice is in the interests of Holders of the Series.

Section 7.06. Reports by Trustee to Holders.

     Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, the Trustee shall mail to each Securityholder a brief
report dated as of such May 15 that complies with TIA ss. 313(a) (but if no
event described in TIA ss. 313(2) has occurred within the twelve months
preceding the reporting date no report need be transmitted).  The Trustee also
shall comply with TIA ss. 313(b).

     A copy of each report at the time of its mailing to Securityholders shall
be delivered to the Company and filed by the Trustee with the SEC and each
national securities exchange on

                                    - 25 -
<PAGE>

which the Securities are listed. The Company agrees to notify the Trustee of
each national securities exchange on which the Securities are listed.

Section 7.07. Compensation and Indemnity.

     The Company shall pay to the Trustee or predecessor trustee from time to
time reasonable compensation for their respective services subject to any
written agreement between the Trustee and the Company.  The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it.  Such expenses shall include the reasonable compensation and
expenses of the Trustee's agents and counsel.  The Company shall indemnify the
Trustee and each predecessor trustee, its officers, directors, employees and
agents and hold it harmless against any loss, liability or expense incurred or
made by or on behalf of it in connection with the administration of this
Indenture or the trust hereunder and its duties hereunder including the costs
and expenses of defending itself against or investigating any claim in the
premises.  The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity.  The Company need not reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through the Trustee's, or
its officers', directors', employees' or agents' negligence or bad faith.

     To ensure the Company's payment obligations in this Section, the Trustee
shall have a claim prior to the Securities on all money or property held or
collected by the Trustee, except that held in trust to pay principal of or
interest on particular Securities.  When the Trustee incurs expenses or renders
services in connection with an Event of Default specified in Section 6.01 or in
connection with Article Six hereof, the expenses (including the reasonable fees
and expenses of its counsel) and the compensation for services in connection
therewith are to constitute expenses of administration under any bankruptcy law.

Section 7.08. Replacement of Trustee.

     The Trustee may resign by so notifying the Company.  The Holders of a
majority in principal amount of the outstanding Securities may remove the
Trustee by so notifying the removed Trustee in writing and may appoint a
successor trustee with the Company's consent. Such resignation or removal shall
not take effect until the appointment by the Securityholders or the Company as
hereinafter provided of a successor trustee and the acceptance of such
appointment by such successor trustee.  The Company may remove the Trustee and
any Securityholder may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor trustee for any or no
reason, including if:

          (1) the Trustee fails to comply with Section 7.10 after written
request by the Company or any bona fide Securityholder who has been a
Securityholder for at least six months;

          (2) the Trustee is adjudged a bankrupt or an insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
its property; or

                                    - 26 -
<PAGE>

          (4) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
trustee.  If a successor trustee does not take office within 45 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or any
Holder may petition any court of competent jurisdiction for the appointment of a
successor trustee.

     A successor trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company.  Immediately after that, the
retiring Trustee shall transfer all property held by it as Trustee to the
successor trustee, the resignation or removal of the retiring Trustee shall
become effective, and the successor trustee shall have all the rights, powers
and duties of the Trustee under this Indenture.  A successor trustee shall mail
notice of its succession to each Securityholder.

Section 7.09. Successor Trustee by Merger, Etc.

     If the Trustee consolidates with, merges with or into or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor trustee.

Section 7.10. Eligibility; Disqualification.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss. 310(a)(1).  The Trustee shall have a combined capital and surplus of
at least $10,000,000 as set forth in its most recent published annual report of
condition.  The Trustee shall comply with TIA ss. 310(b).

Section 7.11. Preferential Collection of Claims Against Company.

     The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                             Discharge of Indenture

Section 8.01. Defeasance upon Deposit of Moneys or U.S. Government Obligations.

              (a) The Company may, at its option and at any time, elect to have
either paragraph (b) or paragraph (c) below be applied to the outstanding
Securities of any Series upon compliance with the applicable conditions set
forth in paragraph (d).

                                    - 27 -
<PAGE>

          (b) Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company shall be deemed to have been
released and discharged from its respective obligations with respect to the
outstanding Securities of a Series on the date the applicable conditions set
forth below are satisfied (hereinafter, "Legal Defeasance").  For this purpose,
such Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Securities of
a Series, which shall thereafter be deemed to be "outstanding" only for the
purposes of the Sections and matters under this Indenture referred to in (i) and
(ii) below, and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned, except
for the following which shall survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of outstanding Securities of a Series to
receive solely from the trust fund described in paragraph (d) below and as more
fully set forth in such paragraph, payments in respect of the principal of and
interest on such Securities when such payments are due and (ii) obligations
listed in Section 8.02, subject to compliance with this Section 8.01.  The
Company may exercise its option under this paragraph (b) notwithstanding the
prior exercise of its option under paragraph (c) below with respect to such
Securities.

          (c) Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (c), the Company shall be released and discharged
from the obligations under any covenant contained in Article Five and any other
covenant contained in the Authorizing Resolution or supplemental indenture
relating to such Series to the extent provided for therein, on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Securities of such Series shall thereafter be deemed to be
not "outstanding" for the purpose of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder.  For this purpose, such Covenant Defeasance
means that, with respect to the outstanding Securities of a Series, 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 covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such 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 6.01(3), but, except as specified above,
the remainder of this Indenture and such Securities shall be unaffected thereby.

          (d) The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Securities of the
applicable Series:

                (1) The Company shall have irrevocably deposited in trust with
the Trustee, pursuant to an irrevocable trust and security agreement in form and
substance reasonably satisfactory to the Trustee, money in U.S. dollars or U.S.
government obligations or a combination thereof in such amounts and at such
times as are sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of and interest on the
outstanding Securities of such Series to maturity or redemption; provided,
however, that the Trustee (or other qualifying trustee) shall have received an
irrevocable written order from the Company instructing the Trustee (or other
qualifying trustee) to apply such money or the

                                    - 28 -

<PAGE>

proceeds of such U.S. government obligations to said payments with respect to
the Securities of such Series to maturity or redemption;

          (2) No Default or Event of Default shall have occurred and be
continuing on the date of such deposit;

          (3) Such deposit will not result in a Default under this Indenture or
a breach or violation of, or constitute a default under, any other material
instrument or agreement to which the Company or any of its Subsidiaries is a
party or by which it or any of their property is bound;

          (4) (i) In the event the Company elects paragraph (b) hereof, the
Company shall deliver to the Trustee an Opinion of Counsel in the United States,
in form and substance reasonably satisfactory to the Trustee, to the effect that
(A) the Company has received from, or there has been published by, the Internal
Revenue Service a ruling or (B) since the Issue Date pertaining to such Series,
there has been a change in the applicable federal income tax law, in either case
to the effect that, and based thereon such Opinion of Counsel shall state that,
or (ii) in the event the Company elects paragraph (c) hereof, the Company shall
deliver to the Trustee an Opinion of Counsel in the United States, in form and
substance reasonably satisfactory to the Trustee, to the effect that, in the
case of clauses (i) and (ii), Holders of the Securities of such Series will not
recognize income, gain or loss for United States federal income tax purposes as
a result of such deposit and the defeasance contemplated hereby and will be
subject to federal income tax in the same amounts and in the same manner and at
the same times as would have been the case if such deposit and defeasance had
not occurred;

          (5) The Company shall have delivered to the Trustee an Officers'
Certificate, stating that the deposit under clause (1) was not made by the
Company with the intent of preferring the Holders of the Securities of such
Series over any other creditors of the Company or with the intent of defeating,
hindering, delaying or defrauding any other creditors of the Company or others;

          (6) The Company shall have delivered to the Trustee an Opinion of
Counsel, reasonably satisfactory to the Trustee, to the effect that, (A) the
trust funds will not be subject to the rights of Holders of Indebtedness of the
Company other than the Securities of such Series and (B)  assuming no
intervening bankruptcy of the Company between the date of deposit and the 91st
day following the deposit and that no Holder of Securities of such Series is an
insider of the Company, after the 91st day following the deposit, the trust
funds will not be subject to any applicable bankruptcy, insolvency,
reorganization or similar law affecting creditors' rights generally; and

          (7) The Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent specified
herein relating to the defeasance contemplated by this Section 8.01 have been
complied with.

     In the event all or any portion of the Securities of a Series are to be
redeemed through such irrevocable trust, the Company must make arrangements
satisfactory to the Trustee, at the

                                    - 29 -

<PAGE>

time of such deposit, for the giving of the notice of such redemption or
redemptions by the Trustee in the name and at the expense of the Company.

     (e) In addition to the Company's rights above under this Section 8.01, the
Company may terminate all of its obligations under this Indenture with respect
to a Series when:

          (1) All Securities of such Series theretofore authenticated and
delivered (other than Securities which have been destroyed, lost or stolen and
which have been replaced or paid as provided in Section 2.07 and Securities for
whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged
from such trust) have been delivered to the Trustee for cancellation or all such
Securities not theretofore delivered to the Trustee for cancellation have become
due and payable and the Company has irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust solely for that purpose an
amount of money sufficient to pay and discharge the entire Indebtedness on the
Securities not theretofore delivered to the Trustee for cancellation, for
principal of and interest;

          (2) The Company has paid or caused to be paid all other sums payable
hereunder by the Company;

          (3) The Company has delivered irrevocable instructions to the Trustee
to apply the deposited money toward the payment of the Securities at maturity or
redemption, as the case may be; and

          (4) The Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, stating that all conditions precedent specified
herein relating to the satisfaction and discharge of this Indenture have been
complied with.

Section 8.02. Survival of the Company's Obligations.

     Notwithstanding the satisfaction and discharge of the Indenture under
Section 8.01, the Company's obligations in paragraph 9 of the Securities and
Sections 2.03 through 2.07, 4.01, 7.07, 7.08, 8.04 and 8.05, however, shall
survive until the Securities of an applicable Series are no longer outstanding.
Thereafter, the Company's obligations in paragraph 9 of the Securities of such
Series and Sections 7.07, 8.04 and 8.05 shall survive (as they relate to such
Series).

Section 8.03. Application of Trust Money.

     The Trustee shall hold in trust money or U.S. government obligations
deposited with it pursuant to Section 8.01.  It shall apply the deposited money
and the money from U.S. government obligations in accordance with this Indenture
to the payment of principal of and interest on the Securities of the defeased
Series.

<PAGE>

Section 8.04. Repayment to the Company.

     The Trustee and the Paying Agent shall promptly pay to the Company upon
request any excess money or securities held by them at any time.  The Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two
years; 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 a newspaper of general circulation in the City of New York
or mail to each such Holder 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, any unclaimed balance of such money then
remaining will be repaid to the Company.  After payment to the Company,
Securityholders entitled to the money must look to the company for payment as
general creditors unless applicable abandoned property law designates another
person and all liability of the Trustee or such Paying Agent with respect to
such money shall cease.

Section 8.05. Reinstatement.

     If the Trustee is unable to apply any money or U.S. government obligations
in accordance with Section 8.01 by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture and the Securities relating to the Series shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.01 until
such time as the Trustee is permitted to apply all such money or U.S. government
obligations in accordance with Section 8.01; provided, however, that (a) if the
Company has made any payment of interest on or principal of any Securities of
the Series because of the reinstatement of their obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. government obligations held by the Trustee and
(b) unless otherwise required by any legal proceeding or any order or judgment
of any court or governmental authority, the Trustee shall return all such money
or U.S. government obligations to the Company promptly after receiving a written
request therefor at any time, if such reinstatement of the Company's obligations
has occurred and continues to be in effect.

Section 9.02. With Consent of Holders.

     The Company and the Trustee may amend or supplement this Indenture or the
Securities of a Series without notice to any Securityholder of such Series but
with the written consent of the Holders of at least a majority in principal
amount of the outstanding Securities of each such Series affected by the
amendment.  Each such Series shall vote as a separate class.  The Holders of a
majority in principal amount of the outstanding Securities of any Series may
waive compliance by the Company with any provision of the Securities of such
Series or of this Indenture relating to such Series without notice to any
Securityholder.  Without the consent of each Securityholder of a Series
affected, however, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.04, may not:

     (1) reduce the amount of Securities of such Series whose Holders must
consent to an amendment, supplement or waiver;

     (2) reduce the rate of or change the time for payment of interest,
including defaulted interest, on any Security;

     (3) reduce the principal of or change the fixed maturity of any Security or
alter the provisions (including related definitions) with respect to redemption
of Securities pursuant to Article Three hereof or with respect to any
obligations on the part of the Company to offer to purchase or to redeem
Securities of a Series pursuant to the Authorizing Resolution or supplemental
indenture pertaining to such Series;

     (4) modify the ranking or priority of the Securities of any Series;

     (5) make any change in Sections 6.04, 6.07 or this Section 9.02;

     (6) waive a continuing Default or Event of Default in the payment of the
principal of or interest on any Security; or

                                    - 32 -

<PAGE>

     (7) make any Security payable at a place or in money other than that stated
in the Security, or impair the right of any Securityholder to bring suit as
permitted by Section 6.07.

     An amendment of a provision included solely for the benefit of one or more
Series does not affect the interests of Securityholders of any other Series.

     It shall not be necessary for the consent of the Holders under this Section
to approve the particular form of any proposed supplement, but it shall be
sufficient if such consent approves the substance thereof.

Section 9.03. Compliance with Trust Indenture Act.

     Every amendment to or supplement of this Indenture or the Securities shall
comply with the TIA as then in effect.

Section 9.04. Revocation and Effect of Consents.

     A consent to an amendment, supplement or waiver by a Holder shall bind the
Holder and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent is not made on any Security. Subject to the following paragraph, any
such Holder or subsequent Holder, however, may revoke the consent as to his
Security or portion of a Security.  Such revocation shall be effective only if
the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders of Securities of any Series entitled to
consent to any amendment, supplement or waiver, which record date shall be at
least 10 days prior to the first solicitation of such consent.  If a record date
is fixed, then notwithstanding the last sentence of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date.  No such consent shall be valid or effective for more
than 90 days after such record date.

     After an amendment, supplement or waiver becomes effective, it shall bind
every Holder, unless it makes a change described in any of clauses  (1) through
(7) of Section 9.02, in which case, the amendment, supplement or waiver shall
bind only each Holder of a Security who has consented to it and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security; provided, that any such waiver shall not
impair or affect the right of any Holder to receive payment of principal of and
interest on a Security, on or after the respective due dates expressed in such
Security, or to bring suit for the enforcement of any such payment on or after
such respective dates without the consent of such Holder.

Section 9.05.  Notation on or Exchange of Securities.

     If an amendment, supplement or waiver changes the terms of a Security, the
Company may require the Holder of the Security to deliver it to the Trustee, at
which time the Trustee shall place an appropriate notation on the Security about
the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determines, the Company in exchange for the Security shall issue
and the Trustee shall authenticate a new Security that reflects the changed
terms.

 Section 9.06. Trustee to Sign Amendments, Etc.

     Subject to Section 7.02(b), the Trustee shall sign any amendment,
supplement or waiver authorized pursuant to this Article if the amendment,
supplement or waiver does not adversely affect the rights, duties, liabilities
or immunities of the Trustee.  If it does, the Trustee may but need not sign it.
In signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive and shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel as conclusive evidence
that such amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms.

Certificate or in any indenture supplemental hereto.

     The creation and issuance of a Series and the authentication and delivery
thereof are not subject to any conditions precedent.

Section 2.02.  Execution and Authentication

     Two Officers shall sign, or one Officer shall sign and one Officer shall
attest to, the Securities for the Company by manual or facsimile signature.  The
Company's seal shall be reproduced on the Securities.  If an Officer whose
signature is on a Security no longer holds that office at the time the Trustee
authenticates the Security, the Security shall nevertheless be valid.

     A Security shall not be valid until the Trustee manually signs the
certificate of authentication on the Security.  The signature shall be
conclusive evidence that the Security has been authenticated under this
Indenture.  The Trustee shall authenticate Securities for original issue upon
receipt of an Officers' Certificate of the Company.  Each Security shall be
dated the date of its authentication.

Section 2.03.  Registrar and Paying Agent

     The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("Registrar"), an office
or agency where Securities may be presented for payment ("Paying Agent) and an
office or agency where notices and demands to or upon the Company in respect of
the Securities and this Indenture may be served.  The Registrar shall keep a
register of the Securities and of their transfer and exchange.  The Company may
have one or more co-Registrars and one or more additional paying agents.  The
term "Paying Agent" includes any additional paying agent.

     The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture.  The agreement shall implement the provisions of
this Indenture that relate to such Agent.  The Company shall promptly notify the
Trustee in writing of the name and address of any such Agent and the Trustee
shall have the right to inspect the Securities register at all reasonable times
to obtain copies thereof, and the Trustee shall have the right to rely upon such
register as to the names and addresses of the Holders and the principal amounts
and certificate numbers thereof.  If the Company fails to maintain a Registrar
or Paying Agent or fails to give the foregoing notice, the Trustee shall act as
such.

     The Company initially appoints the Trustee as Registrar and Paying Agent.

Section 2.04.  Paying Agent to Hold Money in Trust

     Each Paying Agent shall hold in trust for the benefit of Securityholders
and the Trustee all money held by the Paying Agent for the payment of principal
of or interest on the Securities, and shall notify the Trustee of any default by
the Company in making any such payment.  If the Company or a Subsidiary acts as
Paying Agent, it shall segregate the money and hold it as a separate trust fund.
The Company at any time may require a Paying Agent to pay all money held by it
to the Trustee.  Upon doing so the Paying Agent shall have no further liability
for the money.


                                      -9-
<PAGE>

Section 2.05.  Securityholder Lists

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders.  If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least 5 Business Days before each semi-annual interest payment
date and at such other times as the Trustee may request in writing a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Securityholders.

Section 2.06.  Transfer and Exchange

     Where a Security is presented to the Registrar or a co-Registrar with a
request to register a transfer, the Registrar shall register the transfer as
requested if the requirements of Section 8-401(1) of the New York Uniform
Commercial Code are met.  Where Securities are presented to the Registrar or a
co-Registrar with a request to exchange them for an equal principal amount of
Securities of other denominations, the Registrar shall make the exchange as
requested if the same requirements are met.  To permit transfers and exchanges,
the Trustee shall authenticate Securities at the Registrar's request.  The
Registrar need not transfer or exchange any Security selected for redemption,
except the unredeemed part thereof if the Security is redeemed in part, or
transfer or exchange any Securities for a period of 15 days before a selection
of Securities to be redeemed.  Any exchange or transfer shall be without charge,
except that the Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto except in
the case of exchanges pursuant to 2.09, 3.06, or 9.05 not involving any
transfer.

     Any Holder of a global Security shall, by acceptance of such global
Security, agree that transfers of beneficial interests in such global Security
may be effected only through a book entry system maintained by the Holder of
such global Security (or its agent), and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry.

Section 2.07.  Replacement Securities

     If the Holder of a Security claims that the Security has been lost,
destroyed, mutilated or wrongfully taken, the Company shall issue and, upon
written request of any Officer of the Company, the Trustee shall authenticate a
replacement Security; provided, however, in the case of a lost, destroyed or
wrongfully taken Security, that the requirements of Section 8-405 of the New
York Uniform Commercial Code are met.  If any such lost, destroyed, mutilated or
wrongfully taken Security shall have matured or shall be about to mature, the
Company may, instead of issuing a substitute Security therefor, pay such
Security without requiring (except in the case of a mutilated Security) the
surrender thereof.  An indemnity bond must be sufficient in the judgment of the
Company and the Trustee to protect the Company, the Trustee or any Agent from
any loss which any of them may suffer if a Security is replaced, including the
acquisition of such Security by a bona fide purchaser.  The Company or the
Trustee may charge the Holder for expenses in replacing a Security.


                                     -10-
<PAGE>

Section 2.08.  Outstanding Securities

     Securities outstanding at any time are all Securities authenticated by the
Trustee except for those canceled by it and those described in this Section.  A
Security does not cease to be outstanding because the Company or one of its
Affiliates holds the Security.

     If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

     If, on a redemption date or maturity date, the Paying Agent holds money
sufficient to pay Securities payable on that date, then on and after that date
such Securities cease to be outstanding and interest on them ceases to accrue.

     Subject to the foregoing provisions of this Section, 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.

Section 2.09.  Temporary Securities

     Until definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Securities.  Temporary Securities
shall be substantially in the form of definitive Securities but may have
variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and, upon surrender for
cancellation of the temporary Security, the Company shall execute and the
Trustee shall authenticate definitive Securities in exchange for temporary
Securities.  Until so exchanged, the temporary Securities shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
authenticated and delivered hereunder.

Section 2.10.  Cancellation

     The Company at any time may deliver Securities to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange,
redemption or payment.  The Trustee and no one else shall cancel and destroy, or
retain in accordance with its standard retention policy, all Securities
surrendered for registration or transfer, exchange, redemption, paying or
cancellation.  Unless the Authorizing Resolution so provides, the Company may
not issue new Securities to replace Securities that it has previously paid or
delivered to the Trustee for cancellation.

Section 2.11.  Defaulted Interest

     If the Company defaults in a payment of interest on the Securities, it
shall pay the defaulted interest plus any interest payable on the defaulted
interest to the persons who are Securityholders on a subsequent special record
date.  The Company shall fix such special record


                                     -11-
<PAGE>

date and a payment date which shall be reasonably satisfactory to the Trustee.
At least 15 days before such special record date, the Company shall mail to each
Securityholder a notice that states the record date, the payment date and the
amount of defaulted interest to be paid. On or before the date such notice is
mailed, the Company shall deposit with the Paying Agent money sufficient to pay
the amount of defaulted interest to be so paid. The Company may pay defaulted
interest in any other lawful manner if, after notice given by the Company to the
Trustee of the proposed payment, such manner of payment shall be deemed
practicable by the Trustee.

Section 2.12.  Treasury Securities

     In determining whether the Holders of the required principal amount of
Securities of a Series have concurred in any direction, waiver, consent or
notice, Securities owned by the Company or any of its Subsidiaries shall be
considered as though they are not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which the Trustee actually knows
are so owned shall be so considered.

Section 2.13.  CUSIP Numbers

     The Company in issuing the Securities of any Series may use a "CUSIP"
number, and if so, the Trustee shall use the CUSIP number in notices of
redemption or exchange as a convenience to Holders of such Securities; provided
that no representation is hereby deemed to be made by the Trustee as to the
correctness or accuracy of any such CUSIP number printed in the notice or on
such Securities, and that reliance may be placed only on the other
identification numbers printed on such Securities.  The Company shall promptly
notify the Trustee of any change in any CUSIP number.

Section 2.14.  Deposit of Moneys

     Prior to 11:00 a.m.  New York City time on each interest payment date and
maturity date with respect to each Series of Securities, the Company shall have
deposited with the Paying Agent in immediately available funds money sufficient
to make cash payments due on such interest payment date or maturity date, as the
case may be, in a timely manner which permits the Paying Agent to remit payment
to the Holders on such interest payment date or maturity date, as the case may
be.

Section 2.15.  Book-Entry Provisions for Global Security

     (a) Any global Security of a Series initially shall (i) be registered in
the name of the depository who shall be identified in the Authorizing Resolution
or supplemental indenture relating to such Securities (the "Depository") or the
nominee of such Depository, (ii) be delivered to the Trustee as custodian for
such Depository and (iii) bear any required legends.  Members of, or
participants in, the Depository ("Agent Members") shall have no rights under
this Indenture with respect to any global Security held on their behalf by the
Depository, or the Trustee as its custodian, or under the global Security, and
the Depository may be treated by the Company, the


                                     -12-
<PAGE>

Trustee and any agent of the Company or the Trustee as the absolute owner of the
global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or
other authorization furnished by the Depository or impair, as between the
Depository and its Agent Members, the operation of customary practices governing
the exercise of the rights of a Holder of any Security.

     (b) Transfers of any global Security shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees.  Interests of beneficial owners in the global Security may be
transferred or exchanged for definitive Securities in accordance with the rules
and procedures of the Depository.  In addition, definitive Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests
in a global Security if (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository for the global Security and a
successor depository is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing and the
Registrar has received a request from the Depository to issue definitive
Securities.

     (c) In connection with any transfer or exchange of a portion of the
beneficial interest in any global Security to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more definitive Securities are to
be issued) reflect on its books and records the date and a decrease in the
principal amount of the global Security in an amount equal to the principal
amount of the beneficial interest in the global Security to be transferred, and
the Company shall execute, and the Trustee shall authenticate and deliver, one
or more definitive Securities of like tenor and amount.

     (d) In connection with the transfer of an entire global Security to
beneficial owners pursuant to paragraph (b), the global Security shall be deemed
to be surrendered to the Trustee for cancellation, and the Company shall
execute, and the Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in exchange for its beneficial interest in
the global Security, an equal aggregate principal amount of definitive
Securities of authorized denominations.

     (e) The Holder of any global Security may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities of such Series.

                                  Redemption

Section 3.01.  Notices to Trustee

     Securities of a Series that are redeemable prior to maturity shall be
redeemable in accordance with their terms and, unless the Authorizing Resolution
or supplemental indenture provides otherwise, in accordance with this Article.

     If the Company wants to redeem Securities pursuant to Paragraph 5 of the
Securities, it shall notify the Trustee in writing of the Redemption Date and
the principal amount of Securities to be redeemed.  Any such notice may be
canceled at any time prior to notice of such redemption being mailed to Holders.
Any such canceled notice shall be void and of no effect.

     If the Company wants to credit any Securities previously redeemed, retired
or acquired against any redemption pursuant to Paragraph 6 of the Securities, it
shall notify the Trustee of the amount of the credit and it shall deliver any
Securities not previously delivered to the Trustee for cancellation with such
notice.

     The Company shall give each notice provided for in this Section 3.01 at
least 30 days before the notice of any such redemption is to be mailed to
Holders (unless a shorter notice shall be satisfactory to the Trustee).

Section 3.02.  Selection of Securities to be Redeemed

     If fewer than all of the Securities of a Series are to be redeemed, the
Trustee shall select the Securities to be redeemed by a method the Trustee
considers fair and appropriate.  The Trustee shall make the selection from
Securities outstanding not previously called for redemption and shall promptly
notify the Company of the serial numbers or other identifying attributes of the
Securities so selected.  The Trustee may select for redemption portions of the
principal of Securities that have denominations larger than the minimum
denomination for the Series. Securities and portions of them it selects shall be
in amounts equal to the minimum denomination for the Series or an integral
multiple thereof.  Provisions of this Indenture that apply to Securities called
for redemption also apply to portions of Securities called for redemption.

Section 3.03.  Notice of Redemption

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail a notice of redemption by first-class mail, postage prepaid,
to each Holder of Securities to be redeemed.


                                     -14-
<PAGE>

     The notice shall identify the Securities to be redeemed and shall state:

     (1) the redemption date;

     (2) the redemption price;

     (3) the name and address of the Paying Agent;

     (4) that Securities called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

     (5) that interest on Securities called for redemption ceases to accrue on
and after the redemption date; and

     (6) that the Securities are being redeemed pursuant to the mandatory
redemption or the optional redemption provisions, as applicable.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
shall deliver to the Trustee at least 15 days prior to the date on which notice
of redemption is to be mailed or such shorter period as may be satisfactory to
the Trustee, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

Section 3.04.  Effect of Notice of Redemption

     Once notice of redemption is mailed, Securities called for redemption
become due and payable on the redemption date and at the redemption price as set
forth in the notice of redemption.  Upon surrender to the Paying Agent, such
Securities shall be paid at the redemption price, plus accrued interest to the
redemption date.

Section 3.05.  Deposit of Redemption Price

     On or before the redemption date, the Company shall deposit with the Paying
Agent immediately available funds sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date.

Section 3.06.  Securities Redeemed in Part

     Upon surrender of a Security that is redeemed in part, the Company shall
execute and the Trustee shall authenticate for each Holder a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

Section 4.01.  Payment of Securities

     The Company shall pay the principal of and interest on a Series on the
dates and in the manner provided in the Securities of the Series.  An
installment of principal or interest shall be considered paid on the date it is
due, if on that date the Paying Agent holds money designated for and sufficient
to pay the installment; provided, however, that money held by the Paying Agent
for the benefit of holders of Senior Indebtedness pursuant to the provisions of
Article 11 hereof shall not be considered paid within the meaning of this
Section 4.01.

     The Company shall pay interest on overdue principal at the rate borne by
the Series; it shall pay interest on overdue installments of interest at the
same rate.

Section 4.02.  Maintenance of Office or Agency

     The Company shall maintain the office or agency required under Section
2.03.  The Company shall give prior written notice to the Trustee of the
location, and any change in the location, of such office or 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 address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee.

Section 4.03.  Compliance Certificate

     The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company an Officers' Certificate stating whether or not
the signers know of any Default by the Company in performing any of its
obligations under this Indenture.  If they do know of such a Default, the
certificate shall describe the Default.

Section 4.04.  Payment of Taxes; Maintenance of Corporate Existence;
Maintenance of Properties

     The Company will:

          (a) cause to be paid and discharged all lawful taxes, assessments and
     governmental charges or levies imposed upon the Company and its Restricted
     Subsidiaries or upon the income or profits of the Company and its
     Restricted Subsidiaries or upon property or any part thereof belonging to
     the Company and its Restricted Subsidiaries before the same shall be in
     default, as well as all lawful claims for labor, materials and supplies
     which, if unpaid, might become a lien or charge upon such property or any
     part thereof; provided, however, that the Company shall not be required to
     cause to be paid or discharged any such tax, assessment, charge, levy or
     claim so long


                                     -16-
<PAGE>

     as the validity or amount thereof shall be contested in good faith by
     appropriate proceedings and the nonpayment thereof does not, in the
     judgment of the Company, materially adversely affect the ability of the
     Company and the Restricted Subsidiaries to pay all obligations under this
     Indenture when due; and provided further, that the Company shall not be
     required to cause to be paid or discharged any such tax, assessment,
     charge, levy or claim if, in the judgment of the Company, such payment
     shall not be advantageous to the Company in the conduct of its business and
     if the failure so to pay or discharge does not, in its judgment, materially
     adversely affect the ability of the Company and the Restricted Subsidiaries
     to pay all obligations under this Indenture when due;

          (b) cause to be done all things necessary to preserve and keep in full
     force and effect the corporate existence of the Company and each of its
     Restricted Subsidiaries; provided, however, that nothing in this subsection
     (b) shall prevent a consolidation or merger of the Company or any
     Restricted Subsidiary not prohibited by the provisions of Article Five or
     any other provision or the Authorizing Resolution or supplemental indenture
     pertaining to a Series, and the Company need not maintain the corporate
     existence of an immaterial Restricted Subsidiary; and

          (c) at all times keep, maintain and preserve the property of the
     Company and the Restricted Subsidiaries in good repair, working order and
     condition (reasonable wear and tear excepted) and from time to time make
     all needful and proper repairs, renewals, replacements, betterments and
     improvements thereto, so that the business carried on in connection
     therewith may be properly and advantageously conducted at all times;
     provided, however, that nothing in this subsection (c) shall prevent the
     Company from discontinuing the operation and maintenance of any such
     properties if such discontinuance is, in the judgment of the Company,
     desirable in the conduct of its business and not disadvantageous in any
     material respect to the ability of the Company and the Restricted
     Subsidiaries to pay all obligations under this Indenture when due.

Section 5.01.  When Company May Merge, etc.

     The Company shall not consolidate with or merge with or into, any other
corporation, or transfer all or substantially all of its assets to, any entity
unless permitted by law and unless (1) the resulting, surviving or transferee
entity, which shall be a corporation organized and existing under the laws of
the United States or a State thereof, assumes by supplemental indenture, in a
form reasonably satisfactory to the Trustee, all of the obligations of the
Company under the Securities and this Indenture and (2) immediately after giving
effect to, and as a result of, such transaction, no Default or Event of Default
shall have occurred and be continuing. Thereafter such successor corporation or
corporations shall succeed to and be substituted for the


                                     -17-
<PAGE>

Company with the same effect as if it had been named herein as the "Company" and
all such obligations of the predecessor corporation shall terminate.

     The Company shall deliver to the Trustee prior to the consummation of the
proposed transaction an Officers' Certificate to the foregoing effect and an
Opinion of Counsel stating that the proposed transaction and such supplemental
indenture comply with this Indenture.

     To the extent that an Authorizing Resolution or supplemental indenture
pertaining to any Series provides for different provisions relating to the
subject matter of this Article Five, the provisions in such Authorizing
Resolution or supplemental indenture shall govern for purposes of such Series.

Series when the same becomes due and payable and the continuance of any such
failure for a period of 30 days;

     (2) the failure by the Company to pay the principal or premium of any
Security of such Series when the same becomes due and payable at maturity, upon
acceleration or otherwise;

all material respects with any of its agreements or covenants in, or provisions
of, the Securities of such Series, or this Indenture (as they relate thereto)
and such failure continues for the period and after the notice specified below
(except in the case of a default with respect to Article Five (or any
replacement provisions as contemplated by Article Five), which will constitute
an Event of Default with notice but without passage of time);

     (4) the acceleration of any Indebtedness (other than Non-Recourse
Indebtedness) of the Company or any Restricted Subsidiary in an amount of $30
million or more, individually or in the aggregate, and such acceleration does

30 days after such acceleration;

     (5) the failure by the Company or any Restricted Subsidiary to make any
principal or interest payment in an amount of $30 million or more, individually
or in the aggregate, in respect of Indebtedness for borrowed money (other than
Non-Recourse Indebtedness) of the Company or any Restricted Subsidiary within 30
days of such principal or interest becoming due and payable


                                     -18-
<PAGE>

(after giving effect to any applicable grace period set forth in the documents

     (6) a final judgment or judgments in an amount of $30 million or more,
individually or in the aggregate, for the payment of money having been entered
by a court or courts of competent jurisdiction against the Company or any of its
Restricted Subsidiaries and such judgment or judgments is not covered by a
policy of insurance, satisfied, stayed, annulled or rescinded within 90 days of
being entered;

     (7) the Company or any Restricted Subsidiary that is a Significant

     involuntary case,

         (C) consents to the appointment of a Custodian of it or for all or
     substantially all of its property, or

         (D) makes a general assignment (except in the case of a Restricted
     Subsidiary, to the Company) for the benefit of its creditors; or

     (8) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

         (A) is for relief against the Company or any Restricted Subsidiary that
     is a Significant Subsidiary as debtor in an involuntary case,

         (B) appoints a Custodian of the Company or any Restricted Subsidiary
     that is a Significant Subsidiary or a Custodian for all or substantially
     all of the property of the Company or any Restricted Subsidiary that is a
     Significant Subsidiary, or

         (C) orders the liquidation of the Company or any Restricted Subsidiary
     that is a Significant Subsidiary, and the order or decree remains unstayed
     and in effect for 90 days.

     A Default as described in sub-clause (3) above will not be deemed an Event
of Default until the Trustee notifies the Company, or the Holders of at least 25
percent in principal amount of the then outstanding Securities of the applicable
Series notify the Company and the Trustee, of the Default and (except in the
case of a default with respect to Article Five (or any replacement provisions as
contemplated by Article Five)) the Company does not cure the Default within 90
days after receipt of the notice.  The notice must specify the Default, demand
that it be remedied and state that the notice is a "Notice of Default." If such
a Default is cured within such time period, it ceases.


                                     -19-

     The term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian or similar official under any Bankruptcy Law.

Section 6.02.  Acceleration

     If an Event of Default (other than an Event of Default with respect to the
Company resulting from sub-clauses (7) or (8) above), shall have occurred and be
continuing under the Indenture, the Trustee by notice to the Company, or the
Holders of at least 25 percent in principal amount of the Securities of the
applicable Series then outstanding by notice to the Company and the Trustee, may
declare all Securities of such Series to be due and payable immediately.  Upon
such declaration of acceleration, the amounts due and payable on the Securities
of such Series will be due and payable immediately.  If an Event of Default with
respect to the Company specified in sub-clauses (7) or (8) above occurs, all
amounts due and payable on the Securities of such Series will ipso facto become
and be immediately due and payable without any declaration, notice or other act
on the part of the Trustee and the Company or any Holder.  The Holders of a
majority in principal amount of the Securities of such Series then outstanding
by written notice to the Trustee and the Company may waive any Default or Event
of Default (other than any Default or Event of Default in payment of principal
or interest) with respect to such Series of Securities under the Indenture.
Holders of a majority in principal amount of the then outstanding Securities of
such Series may rescind an acceleration with respect to such Series and its
consequence (except an acceleration due to nonpayment of principal or interest
on the Securities of such Series) if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived.

     No such rescission shall extend to or shall affect any subsequent Event of
Default, or shall impair any right or power consequent thereon.

Section 6.03.  Other Remedies

     If an Event of Default on a Series occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on the Series or to enforce the performance
of any provision in the Securities or this Indenture applicable to the Series.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.

Section 6.04.  Waiver of Existing Defaults

     Subject to Section 9.02, the Holders of a majority in principal amount of
the outstanding Securities of a Series on behalf of all the Holders of the
Series by notice to the Trustee may waive an existing Default on such Series and
its consequences.  When a Default is waived, it is


                                     -20-
<PAGE>

cured and stops continuing, and any Event of Default arising therefrom shall be
deemed to have been cured; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

Section 6.05.  Control by Majority

     The Holders of a majority in principal amount of the outstanding Securities
of a Series 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 it with respect to such Series.  The Trustee, however, may refuse
to follow any direction (i) that conflicts with law or this Indenture, (ii)
that, subject to Section 7.01, the Trustee determines is unduly prejudicial to
the rights of other Securityholders, or (iii) that would involve the Trustee in
personal liability.

Section 6.06.  Limitation on Suits

     A Securityholder of a Series may not pursue any remedy with respect to this
Indenture or the Series unless:

     (1)  the Holder gives to the Trustee written notice of a continuing Event
          of Default on the Series;

     (2)  the Holders of at least a majority in principal amount of the
          outstanding Securities of the Series make a written request to the
          Trustee to pursue the remedy;

     (3)  such Holder or Holders offer to the Trustee indemnity satisfactory to
          the Trustee against any loss, liability or expense;

     (4)  the Trustee does not comply with the request within 90 days after
          receipt of the request and the offer of indemnity; and

     (5)  no written request inconsistent with such written request shall have
          been given to the Trustee pursuant to this Section 6.06.

     A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

Section 6.07.  Rights of Holders to Receive Payment

     Notwithstanding any other provision of this Indenture, the right of any
Holder to receive payment of principal of and interest on the Security, on or
after the respective due dates expressed in the Security, or to bring suit for
the enforcement of any such payment on or after such respective dates, is
absolute and unconditional and shall not be impaired or affected without the
consent of the Holder.


                                     -21-
<PAGE>

Section 6.08.  Collection Suit by Trustee

     If an Event of Default in payment of interest or principal specified in
Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount of principal and interest remaining unpaid.

Section 6.09.  Trustee May File Proofs of Claim

     The Trustee may file such proofs of claim and 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 and counsel) and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property, and unless prohibited by applicable law or regulation, may vote on
behalf of the Holders in any election of a Custodian, and shall be entitled and
empowered to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same and any Custodian in
any such judicial proceeding is hereby authorized by each Securityholder to make
such payments to the Trustee.  Nothing herein shall be deemed to authorize the
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder or to authorize
the Trustee to vote in respect of the claim of any Securityholder except as
aforesaid for the election of the Custodian.

Section 6.10.  Priorities

     If the Trustee collects any money pursuant to this Article, it shall pay
out the money in the following order:

     First:  to the Trustee for amounts due under Section 7.07;

     Second:  to holders of Senior Indebtedness to the extent required by
     Article 11;

     Third:  to Securityholders for amounts due and unpaid on the Securities for
     principal and interest, ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Securities for
     principal and interest, respectively; and

     Fourth:  to the Company as its interests may appear.  The Trustee may fix a
     record date and payment date for any payment to Securityholders pursuant to
     this Section 6.10.

Section 6.11.  Undertaking for Costs

     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, a court in its discretion may


                                     -22-
<PAGE>

require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having the due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section does not apply to a suit by
the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of
more than 10% in principal amount of the Series.

                                 ARTICLE SEVEN

                                    Trustee

Section 7.01.  Duties of Trustee

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall, prior to the receipt of directions from the Holders of a majority in
principal amount of the Securities, exercise its rights and powers and use the
same degree of care and skill in their exercise as a prudent man would exercise
or use under the circumstances in the conduct of his own affairs.

     (b) Except during the continuance of an Event of Default:

         (1) The Trustee need perform only those duties that are specifically
     set forth in this Indenture and no others and no implied covenants or
     obligations shall be read into this Indenture against the Trustee.

         (2) In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of his Indenture. The
     Trustee, however, shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture but need
     not confirm or investigate the accuracy of mathematical calculations or
     other facts or matters stated herein.

     (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except
that:

         (1) This paragraph does not limit the effect of paragraph (b) of this
     Section.

         (2) The Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer, unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts.

         (3) The Trustee shall not be liable with respect to any action it takes
     or omits to take in good faith in accordance with a direction received by
     it pursuant to Section 6.05 or any other direction of the Holders permitted
     hereunder.


                                     -23-

Trustee is subject to paragraphs (a), (b) and (c) of this Section.

power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

it except as the Trustee may agree with the Company.  Money held in trust by the
Trustee need not be segregated from other funds except to the extent required by
law.

     (g) None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties or in the exercise of any of its rights
or powers, if there shall be reasonable grounds for believing that the repayment
of such funds or adequate indemnity against such liability is not reasonably
assured to it.

Section 7.02.  Rights of Trustee

     Subject to Section 7.01:

     (a) The Trustee may rely and shall be protected in acting or refraining
from acting on any document, resolution, certificate, instrument, report, or

the proper person.  The Trustee need not investigate any fact or matter stated
in the document, resolution, certificate, instrument, report, or direction.

     (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both, which shall conform to
Sections 10.04 and 10.05 hereof and containing such other statements as the
Trustee reasonably deems necessary to perform its duties hereunder.  The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on the Officers' Certificate, Opinion of Counsel or any other direction
of the Company permitted hereunder.

     (c) The Trustee may act through agents and shall not be responsible for the
misconduct or negligence of any agent appointed with due care.

omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture.

     (e) The Trustee may consult with counsel, and the written advice of such
counsel or any Opinion of Counsel as to matters of law shall be full and

suffered by it hereunder in good faith and in accordance with the advice or
opinion of such counsel.

to have notice or knowledge of any Event of Default (other than under Section
6.01(1) or 6.01(2)) unless a Trust Officer assigned to and working in the
Trustee's corporate trust office has actual knowledge thereof or unless written
notice of any Event of Default is received by the Trustee at its address
specified in Section 10.02 hereof and such notice references the Securities
generally, the Company or this Indenture.

Section 7.03.  Individual Rights of Trustee

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or its Affiliates
with the same rights it would have if it were not Trustee.  Any Agent may do the
same with like rights.  The Trustee, however, must comply with Sections 7.10 and
7.11.

Section 7.04.  Trustee's Disclaimer

     The Trustee makes no representation as to the validity or adequacy of this
Indenture, the Securities or of any prospectus used to sell the Securities; it
shall not be accountable for the Company's use of the proceeds from the
Securities; it shall not be accountable for any money paid to the Company, or
upon the Company's direction, if made under and in accordance with any provision
of this Indenture; it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee; and it shall not be
responsible for any statement of the Company in this Indenture or in the
Securities other than its certificate of authentication.

Section 7.05.  Notice of Defaults

     If a Default on a Series occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Securityholder of the Series notice of
the Default (which shall specify any uncured Default known to it) within 90 days
after it occurs.  Except in the case of a default in payment of principal of or
interest on a Series, the Trustee may withhold the notice if and so long as the
board of directors of the Trustee, the executive or any trust committee of such
directors and/or responsible officers of the Trustee in good faith determine(s)
that withholding the notice is in the interests of Holders of the Series.

Section 7.06.  Reports by Trustee to Holders

     Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, the Trustee shall mail to each Securityholder a brief
report dated as of such May 15 that complies with TIA ss.313(a) (but if no event
described in TIA ss.313(2) has occurred within the twelve months preceding the
reporting date no report need be transmitted).  The Trustee also shall comply
with TIA ss.313(b).


                                     -25-
<PAGE>

     A copy of each report at the time of its mailing to Securityholders shall
be delivered to the Company and filed by the Trustee with the SEC and each
national securities exchange on which the Securities are listed.  The Company
agrees to notify the Trustee of each national securities exchange on which the
Securities are listed.

Section 7.07.  Compensation and Indemnity

     The Company shall pay to the Trustee or predecessor trustee from time to
time reasonable compensation for their respective services subject to any
written agreement between the Trustee and the Company.  The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it.  Such expenses shall include the reasonable compensation and
expenses of the Trustee's agents and counsel.  The Company shall indemnify the
Trustee and each predecessor trustee, its officers, directors, employees and
agents and hold it harmless against any loss, liability or expense incurred or
made by or on behalf of it in connection with the administration of this
Indenture or the trust hereunder and its duties hereunder including the costs
and expenses of defending itself against or investigating any claim in the
premises.  The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity.  The Company need not reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through the Trustee's, or
its officers', directors', employees' or agents' negligence or bad faith.

     To ensure the Company's payment obligations in this Section, the Trustee
shall have a claim prior to the Securities on all money or property held or
collected by the Trustee, except that held in trust to pay principal of or
interest on particular Securities.  When the Trustee incurs expenses or renders
services in connection with an Event of Default specified in Section 6.01 or in
connection with Article 6 hereof, the expenses (including the reasonable fees
and expenses of its counsel) and the compensation for services in connection
therewith are to constitute expenses of administration under any bankruptcy law.

appointment by such successor trustee The Company may remove the Trustee and any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor trustee for any or no reason,

          the Company or any bona fide Securityholder who has been a
          Securityholder for at least six months;

     (2)  the Trustee is adjudged a bankrupt or an insolvent;

Holder may petition any court of competent jurisdiction for the appointment of a
successor trustee.

Section 8.01.  Defeasance upon Deposit of Moneys or U.S Government Obligations

     (a) The Company may, at its option and at any time, elect to have either
paragraph (b) or paragraph (c) below be applied to the outstanding Securities of
any Series upon compliance with the applicable conditions set forth in paragraph
(d).

     (b) Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company shall be deemed to have been
released and discharged from its respective obligations with respect to the
outstanding Securities of a Series on the date the applicable conditions set
forth below are satisfied (hereinafter, "Legal Defeasance").  For this purpose,
such Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Securities of
a Series, which shall thereafter be deemed to be "outstanding" only for the
purposes of the Sections and matters under this Indenture referred to in (i) and
(ii) below, and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned, except
for the following which shall survive until otherwise terminated or discharged
hereunder:  (i) the rights of Holders of outstanding Securities of a Series to
receive solely from the trust fund described in paragraph (d) below and as more
fully set forth in such paragraph, payments in respect of the principal of and
interest on such Securities when such payments are due and (ii) obligations

covenant contained in the Authorizing Resolution or supplemental indenture
relating to such Series to the extent provided for therein, on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Securities of such Series shall thereafter be deemed to be
not "outstanding" for the purpose of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder.  For this purpose, such Covenant Defeasance
means that, with respect to the outstanding Securities of a Series, 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 covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such 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 6.01(3), but, except as specified above,
the remainder of this Indenture and such Securities shall be unaffected thereby.

     and substance reasonably satisfactory to the Trustee, money in U.S. dollars
     or U.S government obligations or a combination thereof in such amounts and
     at such times as are sufficient, in the opinion of a nationally recognized
     firm of independent public accountants, to pay the principal of and
     interest on the outstanding Securities of such Series to maturity or
     redemption; provided, however, that the Trustee (or other qualifying
     trustee) shall have received an irrevocable written order from the Company
     instructing the Trustee (or other qualifying trustee) to apply such money
     or the proceeds of such U.S. government obligations to said payments with
     respect to the Securities of such Series to maturity or redemption;

         (2) No Default or Event of Default shall have occurred and be
     continuing on the date of such deposit;

         (3) Such deposit will not result in a Default under this Indenture or a

     instrument or agreement to which the Company or any of its Subsidiaries is
     a party or by which it or any of their property is bound;

         (4) (i) In the event the Company elects paragraph (b) hereof, the
     Company shall deliver to the Trustee an Opinion of Counsel in the United
     States, in form and substance reasonably satisfactory to the Trustee, to

     recognize income, gain or loss for United States federal income tax
     purposes as a result of such deposit and the defeasance contemplated hereby
     and will be subject to federal income tax in the same amounts and in the
     same manner and at the same times as would have been the case if such
     deposit and defeasance had not occurred;

         (5) The Company shall have delivered to the Trustee an Officers'
     Certificate, stating that the deposit under clause (1) was not made by the
     Company with the intent of preferring the Holders of the Securities of such

     Indebtedness of the Company other than the Securities of such Series and
     (B) assuming no intervening bankruptcy of the Company between the date of
     deposit and the 91st day following the deposit and that no Holder of
     Securities of such Series is an insider of the Company, after the 91st day
     following the deposit, the trust funds will not be subject to any
     applicable bankruptcy, insolvency, reorganization or similar law affecting
     creditors' rights generally; and

         (7) The Company has delivered to the Trustee an Officers' Certificate

     In the event all or any portion of the Securities of a Series are to be
redeemed through such irrevocable trust, the Company must make arrangements
satisfactory to the Trustee, at the time of such deposit, for the giving of the
notice of such redemption or redemptions by the Trustee in the name and at the
expense of the Company.

     (e) In addition to the Company's rights above under this Section 8.01, the
Company may terminate all of its obligations under this Indenture with respect
to a Series when:

         (1) All Securities of such Series theretofore authenticated and
     delivered (other than Securities which have been destroyed, lost or stolen
     and which have been replaced or paid as provided in Section 2.07 and
     Securities for whose payment money has theretofore been deposited in trust
     or segregated and held in trust by the Company and thereafter repaid to the
     Company or discharged from such trust) have been delivered to the Trustee
     for cancellation or all such Securities not theretofore delivered to the
     Trustee for cancellation have become due and payable and the Company has
     irrevocably deposited or caused to be deposited with the Trustee as trust
     funds in trust solely for that purpose an amount of money sufficient to pay
     and discharge the entire Indebtedness on the Securities not theretofore
     delivered to the Trustee for cancellation, for principal of and interest;

         (2) The Company has paid or caused to be paid all other sums payable
     hereunder by the Company;

         (3) The Company has delivered irrevocable instructions to the Trustee
     to apply the deposited money toward the payment of the Securities at
     maturity or redemption, as the case may be; and


                                     -30-
<PAGE>

         (4) The Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, stating that all conditions precedent specified
     herein relating to the satisfaction and discharge of this Indenture have
     been complied with.

Section 8.02.  Survival of the Company's Obligations

     Notwithstanding the satisfaction and discharge of the Indenture under
Section 8.01, the Company's obligations in paragraph 9 of the Securities and
Sections 2.03 through 2.07, 4.01, 7.07, 7.08, 8.04 and 8.05, however, shall
survive until the Securities of an applicable Series are no longer outstanding.
Thereafter, the Company's obligations in paragraph 9 of the Securities of such
Series and Sections 7.07, 8.04 and 8.05 shall survive (as they relate to such
Series).

Section 8.03.  Application of Trust Money

     The Trustee shall hold in trust money or U.S government obligations
deposited with it pursuant to Section 8.01.  It shall apply the deposited money
and the money from U.S government obligations in accordance with this Indenture
to the payment of principal of and interest on the Securities of the defeased
Series.

Section 8.04.  Repayment to the Company

     The Trustee and the Paying Agent shall promptly pay to the Company upon
request any excess money or securities held by them at any time.  The Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two
years; 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 a newspaper of general circulation in the City of New York
or mail to each such Holder 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, any unclaimed balance of such money then
remaining will be repaid to the Company.  After payment to the Company,
Securityholders entitled to the money must look to the Company for payment as
general creditors unless applicable abandoned property law designates another
person and all liability of the Trustee or such Paying Agent with respect to
such money shall cease.

Section 8.05.  Reinstatement

     If the Trustee is unable to apply any money or U.S government obligations
in accordance with Section 8.01 by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture and the Securities relating to the Series shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.01 until
such time as the Trustee is permitted to apply all such money or U.S. government
obligations in accordance with Section 8.01; provided, however, that (a) if the
Company has made any payment of interest on or principal of any Securities of
the Series because of the reinstatement of their obligations,


                                     -31-
<PAGE>

the Company shall be subrogated to the rights of the Holders of such Securities
to receive such payment from the money or U.S government obligations held by the
Trustee and (b) unless otherwise required by any legal proceeding or any order
or judgment of any court or governmental authority, the Trustee shall return all
such money or U.S government obligations to the Company promptly after receiving
a written request therefor at any time, if such reinstatement of the Company's
obligations has occurred and continues to be in effect.

Section 9.01.  Without Consent of Holders

     The Company and the Trustee may amend or supplement this Indenture or the

         (3) to provide that specific provisions of this Indenture shall not
     apply to a Series not previously issued;

         (4) to create a Series and establish its terms;

     of Securityholders.

     After an amendment under this Section 9.01 becomes effective, the Company
shall mail notice of such amendment to the Securityholders.

Section 9.02.  With Consent of Holders

     The Company and the Trustee may amend or supplement this Indenture or the
Securities of a Series without notice to any Securityholder of such Series but
with the written consent of the Holders of at least a majority in principal

waive compliance by the Company with any provision of the Securities of such
Series or of this Indenture relating to such Series without notice to any
Securityholder.  Without the consent of each Securityholder


                                     -32-
<PAGE>

of a Series affected, however, an amendment, supplement or waiver, including a

         (1) reduce the amount of Securities of such Series whose Holders must
     consent to an amendment, supplement or waiver;

         (2) reduce the rate of or change the time for payment of interest,

         (7) make any Security payable at a place or in money other than that
     stated in the Security, or impair the right of any Securityholder to bring
     suit as permitted by Section 6.07.

     An amendment of a provision included solely for the benefit of one or more
Series does not affect the interests of Securityholders of any other Series.

     It shall not be necessary for the consent of the Holders under this Section
to approve the particular form of any proposed supplement, but it shall be
sufficient if such consent approves the substance thereof.

     After the issuance of any Securities, an amendment under this Section or
under Section 9.01 may not make any change that adversely affects in any
material respect the rights under Article 11 of the holders of Senior
Indebtedness, unless such holders of Senior Indebtedness consent to the change.

Section 9.03.  Compliance with Trust Indenture Act

     Every amendment to or supplement of this Indenture or the Securities shall
comply with the TIA as then in effect.

Section 9.04.  Revocation and Effect of Consents

     A consent to an amendment, supplement or waiver by a Holder shall bind the
Holder and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent is not made on any Security Subject to the following paragraph, any
such Holder or subsequent Holder, however, may revoke the consent as to his
Security or portion of a Security.  Such revocation shall be effective only if
the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders of Securities of any Series entitled to
consent to any amendment, supplement or waiver, which record date shall be at
least 10 days prior to the first solicitation of such consent If a record date
is fixed, then notwithstanding the last sentence of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date.  No such consent shall be valid or effective for more
than 90 days after such record date.

     After an amendment, supplement or waiver becomes effective, it shall bind
every Holder, unless it makes a change described in any of clauses (1) through
(7) of Section 9.02, in which case, the amendment, supplement or waiver shall
bind only each Holder of a Security who has consented to it and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security; provided, that any such waiver shall not
impair or affect the right of any Holder to receive payment of principal of and
interest on a Security, on or after the respective due dates expressed in such
Security, or to bring suit for the enforcement of any such payment on or after
such respective dates without the consent of such Holder.

Section 9.05.  Notation on or Exchange of Securities

     If an amendment, supplement or waiver changes the terms of a Security, the
Company may require the Holder of the Security to deliver it to the Trustee, at
which time the Trustee shall place an appropriate notation on the Security about
the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determines, the Company in exchange for the Security shall issue
and the Trustee shall authenticate a new Security that reflects the changed
terms Section 9.06 Trustee to Sign Amendments, etc.

     Subject to Section 7.02(b), the Trustee shall sign any amendment,
supplement or waiver authorized pursuant to this Article if the amendment,
supplement or waiver does not adversely affect the rights, duties, liabilities
or immunities of the Trustee.  If it does, the Trustee may but need not sign it.
In signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive and shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel as conclusive evidence
that such amendment or


                                     -34-
<PAGE>

supplemental indenture is authorized or permitted by this Indenture, that it is
not inconsistent herewith, and that it will be valid and binding upon the
Company in accordance with its terms.

                                ARTICLE ELEVEN

                                 Subordination

Section 11.01.  Agreement to Subordinate

     The Company agrees, and each Securityholder by accepting a Security agrees,
that the indebtedness evidenced by the Securities is subordinated in right of
payment, to the extent and in the manner provided in this Article, to the prior
payment in full of all Senior Indebtedness and that the subordination is for the
benefit of the holders of Senior Indebtedness.

Section 11.02.  Certain Definitions

     "Representative" means the indenture trustee or other trustee, agent or
representative for an issue of Senior Indebtedness.

     "Senior Indebtedness" means all Indebtedness (present or future) created,
incurred, assumed or guaranteed by the Company (and all renewals, extensions or
refundings thereof), unless the instrument under which such Indebtedness is
created, incurred, assumed or guaranteed provides that such Indebtedness is not
senior or superior in right of payment to the Securities. Notwithstanding
anything to the contrary in the foregoing, Senior Indebtedness shall not include
(i) any Indebtedness of the Company to any of its subsidiaries, (ii) any trade
payables of the Company or (iii) guarantees by the Company or any of its
Subsidiaries of Indebtedness (a) outstanding at the date hereof or (b) which may
be outstanding in the future, except that Senior Indebtedness shall include any
guarantees as may be listed in a supplemental indenture and any other present
and future guarantees that provide by their terms that they constitute Senior
Indebtedness.

Section 11.03.  Liquidation; Dissolution; Bankruptcy

     Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its Property:

         (1) holders of Senior Indebtedness shall be entitled to receive payment
     in full in cash of the principal of and interest (including interest
     accruing after the commencement of any such proceeding) to the date of
     payment on the Senior Indebtedness before Securityholders shall be entitled
     to receive any payment of principal of or interest on Securities; and


                                     -38-
<PAGE>

         (2) until the Senior Indebtedness is paid in full in cash, any
     distribution to which Securityholders would be entitled but for this
     Article shall be made to holders of Senior Indebtedness as their interests
     may appear, except that Securityholders may receive securities that are
     subordinated to Senior Indebtedness to at least the same extent as the
     Securities.

     For purposes of this Article 11, a distribution may consist of cash,
securities or other property, by set-off or otherwise.

Section 11.04.  Default on Senior Indebtedness

     Upon the final maturity of any Senior Indebtedness by lapse of time,
acceleration or otherwise, all such Senior Indebtedness shall first be paid in
full, or such payment duly provided for in cash or in a manner satisfactory to
the holders of such Senior Indebtedness, before any payment is made by the
Company or any person  acting on behalf of the Company on account of the
principal or interest of the Securities.

     The Company may not pay principal of or interest on the Securities and may
not acquire any Securities for cash or property (other than capital stock of the
Company or other securities of the Company that are subordinated to Senior
Indebtedness to at least the same extent as the Securities) if a default on
Senior Indebtedness occurs and is continuing that permits holders of such Senior
Indebtedness to accelerate its maturity.

     The Company shall resume payments on the Securities and may acquire them,
if this Article otherwise permits the payment or acquisition at that time, when
the default is cured or waived.

Section 11.05.  Acceleration of Securities

     If payment of the Securities is accelerated because of an Event of Default,
the Company shall promptly notify holders of Senior Indebtedness of the
acceleration.  The Company shall pay the Securities when 180 days pass after the
acceleration occurs if this Article permits the payment at that time; provided,
however, that if no Senior Indebtedness is outstanding at the time of such
acceleration, the Company shall pay the Securities in accordance with the
provisions of Article 6.

Section 11.06  When Distributions Must Be Paid Over

     In the event that the Company shall make any payment to the Trustee on
account of the principal or interest on the Securities at a time when such
payment is prohibited by Section 11.03 or 11.04, such payment shall be held by
the Trustee in trust for the benefit of, and shall forthwith be paid over and
delivered to, the holders of Senior Indebtedness (pro rata as to each of such
holders on the basis of the respective amounts of Senior Indebtedness held by
them) or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Indebtedness may have been issued, as their respective
interests may appear, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to pay all Senior


                                     -39-
<PAGE>

Indebtedness in full in accordance with its terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

     If a distribution is made to Securityholders that because of this Article
should not have been made to them, the Securityholders who receive the
distribution shall hold it in trust for holders of Senior Indebtedness and pay
it over to them as their interests may appear.

Section 11.07. Notice by the Company

     The Company shall promptly notify the Trustee and the Paying Agent of any
facts known to the Company that would cause a payment of principal of or
interest on the Securities to violate this Article, but failure to give such
notice shall not affect the subordination of the Securities to the Senior
Indebtedness provided in this Article.  Nothing in this Article shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 7.07.

Section 11.08.  Subrogation

     After all Senior Indebtedness is paid in full and until the Securities are
paid in full, Securityholders shall be subrogated to the rights of holders of
Senior Indebtedness to receive distributions applicable to Senior Indebtedness
to the extent that distributions otherwise payable to the Securityholders have
been applied to the payment of Senior Indebtedness.  A distribution made under
this Article to holders of Senior Indebtedness which otherwise would have been
made to Securityholders is not, as between the Company and Securityholders, a
payment by the Company on Senior Indebtedness.

Section 11.09.  Relative Rights

     This Article defines the relative rights of Securityholders and holders of
Senior Indebtedness Nothing in this Indenture shall:

         (1) impair, as between the Company and Securityholders, the obligation
     of the Company, which is absolute and unconditional, to pay principal of
     and interest on the Securities in accordance with their terms;

         (2) affect the relative rights of Securityholders and creditors of the
     Company, other than holders of Senior Indebtedness; or

         (3) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default or Event of Default, subject to the
     rights of holders of Senior Indebtedness to receive distributions otherwise
     payable to Securityholders.

     If the Company fails to pay principal of or interest on a Security on the
due date because of this Article, the failure is still a Default or Event of
Default.


                                     -40-
<PAGE>

Section 11.10.  Subordination May Not Be Impaired by the Company

     No right of any holder of Senior Indebtedness to enforce the subordination
of the indebtedness evidenced by the Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

Section 11.11.  Distribution or Notice to the Representative

     Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness pursuant to this Article 11, the distribution may be made
and the notice given to their Representative.

Section 11.12.  Rights of the Trustee and Paying Agent

     Notwithstanding any provision of this Article 11 or any other provision of
this Indenture, the Trustee and Paying Agent shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee or a Paying Agent or the taking of any other
action (pursuant to this Article 11) by the Trustee or a Paying Agent unless and
until the Trustee or such Paying Agent, as the case may be, shall have received
at its office specified in Section 10.02 written notice thereof from the
Company, a Representative or a holder of Senior Indebtedness and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Sections 7.01 and 7.02, and such Paying Agent, shall be entitled in all respects
conclusively to assume that no such facts exist.  The Trustee or Paying Agent
may continue to make payments on the Securities unless it receives such a notice
at least three business days prior to the date upon which payment is due.

     The Trustee shall be entitled to rely reasonably in good faith on the
delivery to it of a written notice by a person representing himself, herself or
itself to be a Representative or a holder of Senior Indebtedness to establish
that such notice has been given by a Representative or a holder of such Senior
Indebtedness.  Only the Company, a Representative or a holder of Senior
Indebtedness that has no Representative may give the notice.

     In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article 11, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such person, the extent to which such person is entitled to participate

such Senior Indebtedness and, subject to the provisions of Section 7.02, the
Trustee shall not be liable to any holder of such Senior Indebtedness if it
shall, in the absence of bad faith, pay over or deliver to holders of
Securities, the Company or any other person monies or assets to which any holder
of such Senior Indebtedness shall be entitled by virtue of this Article 11 or
otherwise.

waives and releases all such liability.  The waiver and release are part of the
consideration for the issue of the Securities.

assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with right of survivorship and not as
tenants in common), CUST (= custodian), and U/G/M/A (= Uniform Gifts to Minors
Act).

16.  Subordination.

     To the extent set forth in Article 11 of the Indenture, the Securities are
subordinated to Senior Indebtedness, which generally is any Indebtedness
outstanding on the date of the Indenture or Indebtedness thereafter created,
incurred, assumed or guaranteed by the Company and all renewals, extensions and

subsidiaries, trade payables of the Company and certain Indebtedness of others
guaranteed by the Company.  To the extent provided in the Indenture, Senior

              and

     (20)     any other terms in addition to or different from those contained
              in this Indenture.

     All Securities of one Series need not be issued at the same time and,
unless otherwise provided, a Series may be reopened for issuances of additional
Securities of such Series pursuant to an Authorizing Resolution, an Officers'
Certificate or in any indenture supplemental hereto.

     The creation and issuance of a Series and the authentication and delivery
     thereof are not subject to any conditions precedent.

 Section 2.02. Execution and Authentication.
               ----------------------------

                                       8
<PAGE>

     Two Officers shall sign, or one Officer shall sign and one Officer shall
attest to, the Securities for the Company by manual or facsimile signature.  The
Company's seal shall be reproduced on the Securities.

     If an Officer whose signature is on a Security no longer holds that office
at the time the Trustee authenticates the Security, the Security shall
nevertheless be valid.

     A Security shall not be valid until the Trustee manually signs the
certificate of authentication on the Security.  The signature shall be
conclusive evidence that the Security has been authenticated under this
Indenture.

     The Trustee shall authenticate Securities for original issue upon receipt
of an Officers' Certificate of the Company.  Each Security shall be dated the
date of its authentication.

Section 2.03. Registrar and Paying Agent.
              --------------------------

     The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("Registrar"), an office
or agency where Securities may be presented for payment ("Paying Agent) and an
office or agency where notices and demands to or upon the Company in respect of
the Securities and this Indenture may be served.  The Registrar shall keep a
register of the Securities and of their transfer and exchange.  The Company may
have one or more co-Registrars and one or more additional paying agents.  The
term "Paying Agent" includes any additional paying agent.

     The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture. The agreement shall implement the provisions of
this Indenture that relate to such Agent. The Company shall promptly notify the
Trustee in writing of the name and address of any such Agent and the Trustee
shall have the right to inspect the Securities register at all reasonable times
to obtain copies thereof, and the Trustee shall have the right to rely upon such
register as to the names and addresses of the Holders and the principal amounts
and certificate numbers thereof. If the Company fails to maintain a Registrar or
Paying Agent or fails to give the foregoing notice, the Trustee shall act as
such.

     The Company initially appoints the Trustee as Registrar and Paying Agent.

Section 2.04. Paying Agent to Hold Money in Trust.
              -----------------------------------

     Each  Paying  Agent  shall  hold in trust for the  benefit of
Securityholders and the Trustee all money held by the Paying Agent for the
payment of principal of or interest on the Securities, and shall notify the
Trustee of any default by the Company in making any such payment.  If the
Company or a Subsidiary acts as Paying Agent, it shall segregate the money and
hold it as a separate trust fund.  The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee.  Upon doing so the Paying
Agent shall have no further liability for the money.

                                       9

Section 2.05. Securityholder Lists.
              --------------------

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders.  If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least 5 Business Days before each semi-annual interest payment
date and at such other times as the Trustee may request in writing a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Securityholders.

Section 2.06. Transfer and Exchange.
              ---------------------

     Where a Security is presented to the Registrar or a co-Registrar with a
request to register a transfer, the Registrar shall register the transfer as
requested if the requirements of Section 8-401(1) of the New York Uniform
Commercial Code are met.  Where Securities are presented to the Registrar or a
co-Registrar with a request to exchange them for an equal principal amount of
Securities of other denominations, the Registrar shall make the exchange as
requested if the same requirements are met.  To permit transfers and exchanges,
the Trustee shall authenticate Securities at the Registrar's request.  The
Registrar need not transfer or exchange any Security selected for redemption,
except the unredeemed part thereof if the Security is redeemed in part, or
transfer or exchange any Securities for a period of 15 days before a selection
of Securities to be redeemed.  Any exchange or transfer shall be without charge,
except that the Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto except in
the case of exchanges pursuant to 2.09, 3.06, or 9.05 not involving any
transfer.

     Any Holder of a global Security shall, by acceptance of such global
Security, agree that transfers of beneficial interests in such global Security
may be effected only through a book entry system maintained by the Holder of
such global Security (or its agent), and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry.

Section 2.07. Replacement Securities.
              ----------------------

     If the Holder of a Security claims that the Security has been lost,
destroyed, mutilated or wrongfully taken, the Company shall issue and, upon
written request of any Officer of the Company, the Trustee shall authenticate a
replacement Security; provided, however, in the case of a lost, destroyed or
wrongfully taken Security, that the requirements of Section 8-405 of the New
York Uniform Commercial Code are met.  If any such lost, destroyed, mutilated or
wrongfully taken Security shall have matured or shall be about to mature, the
Company may, instead of issuing a substitute Security therefor, pay such
Security without requiring (except in the case of a mutilated Security) the
surrender thereof.  An indemnity bond must be sufficient in the judgment of the
Company and the

     Trustee to protect the Company, the Trustee or any Agent from any loss
which any of them may suffer if a Security is replaced, including the
acquisition of such Security by a bona

                                      10
<PAGE>

fide purchaser. The Company or the Trustee may charge the Holder for expenses in
replacing a Security.

Section 2.08. Outstanding Securities.
              ----------------------

     Securities outstanding at any time are all Securities authenticated by the
Trustee except for those canceled by it and those described in this Section.  A
Security does not cease to be outstanding because the Company or one of its
Affiliates holds the Security.

     If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

     If, on a redemption date or maturity date, the Paying Agent holds money
sufficient to pay Securities payable on that date, then on and after that date
such Securities cease to be outstanding and interest on them ceases to accrue.

     Subject to the foregoing provisions of this Section, 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.

Section 2.09. Temporary Securities.
              --------------------

     Until definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Securities.  Temporary Securities
shall be substantially in the form of definitive Securities but may have
variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and, upon surrender for
cancellation of the temporary Security, the Company shall execute and the
Trustee shall authenticate definitive Securities in exchange for temporary
Securities.  Until so exchanged, the temporary Securities shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
authenticated and delivered hereunder.

Section 2.10. Cancellation.
              ------------

     The Company at any time may deliver Securities to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Securities  surrendered to them for registration of transfer,  exchange,
redemption or payment.  The Trustee and no one else shall cancel and destroy, or
retain in accordance with its standard retention policy, all Securities
surrendered for registration or transfer, exchange, redemption, paying or
cancellation.  Unless the Authorizing Resolution so provides, the Company may
not issue new Securities to replace Securities that it has previously paid or
delivered to the Trustee for cancellation.

                                      11
<PAGE>

Section 2.11. Defaulted Interest.
              ------------------

     If the Company defaults in a payment of interest on the Securities, it
shall pay the defaulted interest plus any interest payable on the defaulted
interest to the persons who are Securityholders on a subsequent special record
date.  The Company shall fix such special record date and a payment date which
shall be reasonably satisfactory to the Trustee.  At least 15 days before such
special record date, the Company shall mail to each Securityholder a notice that
states the record date, the payment date and the amount of defaulted interest to
be paid.  On or before the date such notice is mailed, the Company shall deposit
with the Paying Agent money sufficient to pay the amount of defaulted interest
to be so paid.  The Company may pay defaulted interest in any other lawful
manner if, after notice given by the Company to the Trustee of the proposed
payment, such manner of payment shall be deemed practicable by the Trustee.

Section 2.12. Treasury Securities.
              -------------------

     In determining whether the Holders of the required principal amount of
Securities of a Series have concurred in any direction, waiver, consent or
notice, Securities owned by the Company or any of its Subsidiaries shall be
considered as though they are not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which the Trustee actually knows
are so owned shall be so considered.

Section 2.13. CUSIP Numbers.
              -------------

     The Company in issuing the Securities of any Series may use a "CUSIP"
number, and if so, the Trustee shall use the CUSIP number in notices of
redemption or exchange as a convenience to Holders of such Securities; provided
that no representation is hereby deemed to be made by the Trustee as to the
correctness or accuracy of any such CUSIP number printed in the notice or on
such  Securities,  and that  reliance may be placed only on the other
identification numbers printed on such Securities.  The Company shall promptly
notify the Trustee of any change in any CUSIP number.

Section 2.14. Deposit of Moneys.
              -----------------

     Prior to 11:00 a.m. New York City time on each interest payment date and
maturity date with respect to each Series of Securities, the Company shall have
deposited with the Paying Agent in immediately available funds money sufficient
to make cash payments due on such interest payment date or maturity date, as the
case may be, in a timely manner which permits the Paying Agent to remit payment
to the Holders on such interest payment date or maturity date, as the case may
be.

Section 2.15. Book-Entry Provisions for Global Security.
              -----------------------------------------

     (a) Any global Security of a Series initially shall (i) be registered in
the name of the depository who shall be identified in the Authorizing Resolution
or  supplemental  indenture

                                      12
<PAGE>

relating to such Securities (the "Depository") or the nominee of such
Depository, (ii) be delivered to the Trustee as custodian for such Depository
and (iii) bear any required legends.

     Members of, or participants in, the Depository  ("Agent Members") shall
have no rights under this Indenture with respect to any global Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
global Security, and the Depository may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute  owner of the global
Security  for all  purposes  whatsoever.  Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a Holder of any Security.

     (b) Transfers of any global Security shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees.  Interests of beneficial owners in the global Security may be
transferred or exchanged for definitive Securities in accordance with the rules
and procedures of the Depository.  In addition, definitive Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests
in a global Security if (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository for the global Security and a
successor depository is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing and the
Registrar has received a request from the Depository to issue definitive
Securities.

     (c) In connection with any transfer or exchange of a portion of the
beneficial interest in any global Security to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more definitive Securities are to
be issued) reflect on its books and records the date and a decrease in the
principal amount of the global Security in an amount equal to the principal
amount of the beneficial interest in the global Security to be transferred, and
the Company shall execute, and the Trustee shall authenticate and deliver, one
or more definitive Securities of like tenor and amount.

     (d) In connection with the transfer of an entire global Security to
beneficial owners pursuant to paragraph (b), the global Security shall be deemed
to be surrendered to the Trustee for cancellation, and the Company shall
execute, and the Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in exchange for its beneficial interest in
the global Security, an equal aggregate principal amount of definitive
Securities of authorized denominations.

     (e) The Holder of any global Security may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities of such Series.

Section 3.01. Notices to Trustee.
              ------------------

     Securities of a Series that are redeemable prior to maturity shall be
redeemable in accordance with their terms and, unless the Authorizing Resolution
or supplemental indenture provides otherwise, in accordance with this Article.
If the Company wants to redeem Securities pursuant to Paragraph 5 of the
Securities, it shall notify the Trustee in writing of the Redemption Date and
the principal amount of Securities to be redeemed.  Any such notice may be
canceled at any time prior to notice of such redemption being mailed to Holders.
Any such canceled notice shall be void and of no effect.

     If the Company wants to credit any Securities previously redeemed, retired
or acquired against any redemption pursuant to Paragraph 6 of the Securities, it
shall notify the Trustee of the amount of the credit and it shall deliver any
Securities not previously delivered to the Trustee for cancellation with such
notice.

     The Company shall give each notice provided for in this Section 3.01 at
least 30 days before the notice of any such redemption is to be mailed to
Holders (unless a shorter notice shall be satisfactory to the Trustee).

Section 3.02. Selection of Securities to be Redeemed.
              --------------------------------------

     If fewer than all of the Securities of a Series are to be redeemed, the
Trustee shall select the Securities to be redeemed by a method the Trustee
considers fair and appropriate.  The Trustee shall make the selection from
Securities outstanding not previously called for redemption and shall promptly
notify the Company of the serial numbers or other identifying attributes of the
Securities so selected.  The Trustee may select for redemption portions of the
principal of Securities that have denominations larger than the minimum
denomination for the Series. Securities and portions of them it selects shall be
in amounts equal to the minimum denomination for the Series or an integral
multiple thereof.  Provisions of this Indenture that apply to Securities called
for redemption also apply to portions of Securities called for redemption.

Section 3.03. Notice of Redemption.
              --------------------

     At least 30 days but not more than 60 days before a redemption date, the
Company shall mail a notice of redemption by first-class mail, postage prepaid,
to each Holder of Securities to be redeemed.

     The notice shall identify the Securities to be redeemed and shall state:

     (1)  the redemption date;

                                      14
<PAGE>

     (2)  the redemption price;

     (3)  the name and address of the Paying Agent;

     (4)  that Securities called for redemption must be surrendered to the
          Paying Agent to collect the redemption price;

     (5)  that interest on Securities called for redemption ceases to accrue on
          and after the redemption date; and

     (6)  that the Securities are being redeemed pursuant to the mandatory
          redemption or the optional redemption provisions, as applicable.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
shall deliver to the Trustee at least 15 days prior to the date on which notice
of redemption is to be mailed or such shorter period as may be satisfactory to
the Trustee, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

Section 3.04. Effect of Notice of Redemption.
              ------------------------------

     Once notice of redemption is mailed, Securities called for redemption
become due and payable on the redemption date and at the redemption price as set
forth in the notice of redemption.  Upon surrender to the Paying Agent, such
Securities shall be paid at the redemption price, plus accrued interest to the
redemption date.

Section 3.05. Deposit of Redemption Price.
              ---------------------------

     On or before the redemption date, the Company shall deposit with the Paying
Agent immediately available funds sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date.

Section 3.06. Securities Redeemed in Part.
              ---------------------------

     Upon surrender of a Security that is redeemed in part, the Company shall
execute and the Trustee shall authenticate for each Holder a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

Section 4.01. Payment of Securities.
              ---------------------

     The Company shall pay the principal of and interest on a Series on the
dates and in the manner provided in the Securities of the Series.  An
installment of principal or interest shall be considered paid on the date it is
due, if on that date the Paying Agent holds money designated for and sufficient
to pay the installment; provided, however, that money held by the Paying Agent
for the benefit of holders of Senior Indebtedness pursuant to the provisions of
Article 11 hereof shall not be considered paid within the meaning of this
Section 4.01.

     The Company shall pay interest on overdue principal at the rate borne by
the Series; it shall pay interest on overdue installments of interest at the
same rate.

Section 4.02. Maintenance of Office or Agency.
              -------------------------------

     The Company shall maintain the office or agency required under Section
2.03.  The Company shall give prior written notice to the Trustee of the
location, and any change in the location, of such office or 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 address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee.

Section 4.03. Compliance Certificate.
              ----------------------

     The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company an Officers' Certificate stating whether or not

              of Properties.
              -------------

     The Company will:

     (a)      cause to be paid and discharged all lawful taxes, assessments and
              governmental charges or levies imposed upon the Company and its
              Restricted Subsidiaries or upon the income or profits of the
              Company and its Restricted Subsidiaries or upon property or any
              part thereof belonging to the Company and its Restricted
              Subsidiaries before the same shall be in default, as well as all
              lawful claims for labor, materials and supplies which, if unpaid,
              might become a lien or charge upon such property or any part
              thereof; provided, however, that the Company shall not be required
              to cause to be paid or discharged any such tax, assessment,
              charge, levy or claim so long as the validity or amount thereof
              shall be contested in good faith by appropriate proceedings and
              the nonpayment thereof does not, in the judgment of the Company,
              materially adversely affect the ability of the Company and the
              Restricted Subsidiaries to pay all obligations under this
              Indenture when due; and provided further, that the Company shall
              not be required to cause to be paid or discharged any such tax,
              assessment,

              charge, levy or claim if, in the judgment of the Company, such
              payment shall not be advantageous to the Company in the conduct of
              its business and if the failure so to pay or discharge does not,
              in its judgment, materially adversely affect the ability of the
              Company and the Restricted Subsidiaries to pay all obligations
              under this Indenture when due;

     (b)      cause to be done all things necessary to preserve and keep in full
              force and effect the corporate existence of the Company and each
              of its Restricted Subsidiaries; provided, however, that nothing in
              this subsection (b) shall prevent a consolidation or merger of the
              Company or any Restricted Subsidiary not prohibited by the
              provisions of Article Five or any other provision or the
              Authorizing Resolution or supplemental indenture pertaining to a
              Series, and the Company need not maintain the corporate existence
              of an immaterial Restricted Subsidiary ; and

     (c)      at all times keep, maintain and preserve the property of the
              Company and the Restricted Subsidiaries in good repair, working
              order and condition (reasonable wear and tear excepted) and from
              time to time make all needful and proper repairs, renewals,
              replacements, betterments and improvements thereto, so that the
              business carried on in connection therewith may be properly and
              advantageously conducted at all times; provided, however, that
              nothing in this subsection (c) shall prevent the Company from
              discontinuing the operation and maintenance of any such properties
              if such discontinuance is, in the judgment of the Company,
              desirable in the conduct of its business and not disadvantageous
              in any material respect to the ability of the Company and the
              Restricted Subsidiaries to pay all obligations under this
              Indenture when due.

              ---------------------------

     The Company shall not consolidate with or merge with or into, any other
corporation, or transfer all or substantially all of its assets to, any entity
unless permitted by law and unless (1) the resulting, surviving or transferee
entity, which shall be a corporation organized and existing under the laws of
the United States or a State thereof, assumes by supplemental indenture, in a
form reasonably satisfactory to the Trustee, all of the obligations of the
Company under the

Securities and this Indenture and (2) immediately after giving effect to, and as
a result of, such transaction, no Default or Event of Default shall have
occurred and be continuing. Thereafter such successor corporation or
corporations shall succeed to and be substituted for the Company with the same
effect as if it had been named herein as the "Company" and all such obligations
of the predecessor corporation shall terminate.

     The Company shall deliver to the Trustee prior to the consummation of the
proposed transaction an Officers' Certificate to the foregoing effect and an
Opinion of Counsel stating that the proposed transaction and such supplemental
indenture comply with this Indenture.

     To the extent that an Authorizing Resolution or supplemental indenture
pertaining to any Series provides for different provisions relating to the
subject matter of this Article Five, the provisions in such Authorizing
Resolution or supplemental indenture shall govern for purposes of such Series.

                             Defaults and Remedies

Section 6.01. Events of Default.
              -----------------

     An "Event of Default" on a Series occurs if,  voluntarily or involuntarily,
whether by operation of law or otherwise, any of the following occurs:

     (1)      the failure by the Company to pay interest on any Security of such
              Series when the same becomes due and payable and the continuance
              of any such failure for a period of 30 days;

     (2)      the failure by the Company to pay the principal or premium of any
              Security of such Series when the same becomes due and payable at
              maturity, upon acceleration or otherwise;

     (3)      the failure by the Company or any Restricted Subsidiary to comply
              in all material respects with any of its agreements or covenants
              in, or provisions of, the Securities of such Series, or this
              Indenture (as they relate thereto) and such failure continues for
              the period and after the notice specified below (except in the
              case of a default with respect to Article Five (or any replacement
              provisions as contemplated by Article Five), which will constitute
              an Event of Default with notice but without passage of time);

     (4)      the acceleration of any Indebtedness (other than Non-Recourse
              Indebtedness) of the Company or any Restricted Subsidiary in an
              amount of $30 million or more, individually or in the aggregate,
              and such acceleration does not cease to exist, or such
              Indebtedness is not satisfied, in either case within 30 days after
              such acceleration;

                                      18
<PAGE>

     (5)      the failure by the Company or any Restricted Subsidiary to make
              any principal or interest payment in an amount of $30 million or
              more, individually or in the aggregate, in respect of Indebtedness
              for borrowed money (other than Non-Recourse Indebtedness) of the
              Company or any Restricted Subsidiary within 30 days of such
              principal or interest becoming due and payable (after giving
              effect to any applicable grace period set forth in the documents
              governing such Indebtedness);

     (6)      a final judgment or judgments in an amount of $30 million or more,
              individually or in the aggregate, for the payment of money having
              been entered by a court or courts of competent jurisdiction
              against the Company or any of its Restricted Subsidiaries and such
              judgment or judgments is not covered by a policy of insurance,
              satisfied, stayed, annulled or rescinded within 90 days of being
              entered;

     (7)      the Company or any Restricted Subsidiary that is a Significant
              Subsidiary pursuant to or within the meaning of any Bankruptcy
              Law:

              (A)  commences a voluntary case,


              (B)  consents to the entry of an order for relief against it in an
                   involuntary case,

              (C)  consents to the appointment of a Custodian of it or for all
                   or substantially all of its property, or

              (D)  makes a general assignment (except in the case of a
                   Restricted Subsidiary, to the Company) for the benefit of its
                   creditors; or

     (8)      a court of competent jurisdiction enters an order or decree under
              any Bankruptcy Law that:

              (A)  is for relief against the Company or any Restricted
                   Subsidiary that is a Significant Subsidiary as debtor in an
                   involuntary case,

              (B)  appoints a Custodian of the Company or any Restricted
                   Subsidiary that is a Significant Subsidiary or a Custodian
                   for all or substantially all of the property of the Company
                   or any Restricted Subsidiary that is a Significant
                   Subsidiary, or

              (C)  orders the liquidation of the Company or any Restricted
                   Subsidiary that is a Significant Subsidiary, and the order or
                   decree remains unstayed and in effect for 90 days.

     A Default as described in sub-clause (3) above will not be deemed an Event
of Default until the Trustee notifies the Company, or the Holders of at least 25
percent in principal amount

                                      19
<PAGE>

of the then outstanding Securities of the applicable Series notify the Company
and the Trustee, of the Default and (except in the case of a default with
respect to Article Five (or any replacement provisions as contemplated by
Article Five)) the Company does not cure the Default within 90 days after
receipt of the notice. The notice must specify the Default, demand that it be
remedied and state that the notice is a "Notice of Default." If such a Default
is cured within such time period, it ceases.

     The term "Custodian" means any receiver, trustee, assignee, liquidator,
custodian or similar official under any Bankruptcy Law.

Section 6.02. Acceleration.
              ------------

     If an Event of Default (other than an Event of Default with respect to the
Company resulting from sub-clauses (7) or (8) above), shall have occurred and be
continuing under the Indenture, the Trustee by notice to the Company, or the
Holders of at least 25 percent in principal amount of the Securities of the
applicable Series then outstanding by notice to the Company and the Trustee, may
declare all Securities of such Series to be due and payable immediately.  Upon
such declaration of acceleration, the amounts due and payable on the Securities
of such Series will be due and payable immediately.  If an Event of Default with
respect to the Company specified in sub-clauses (7) or (8) above occurs, all
amounts due and payable on the Securities of such Series will ipso facto become
and be immediately due and payable without any declaration, notice or other act
on the part of the Trustee and the Company or any Holder.  The Holders of a
majority in principal amount of the Securities of such Series then outstanding
by written notice to the Trustee and the Company may waive any Default or Event
of Default (other than any Default or Event of Default in payment of principal
or interest) with respect to such Series of Securities under the Indenture.
Holders of a majority in principal amount of the then outstanding Securities of
such Series may rescind an acceleration with respect to such Series and its
consequence (except an acceleration due to nonpayment of principal or interest
on the Securities of such Series) if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived.

     No such rescission shall extend to or shall affect any subsequent Event of
Default, or shall impair any right or power consequent thereon.

Section 6.03. Other Remedies.
              --------------

     If an Event of Default on a Series occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on the Series or to enforce the performance
of any provision in the Securities or this Indenture applicable to the Series.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not

                                      20
<PAGE>

impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. No remedy is exclusive of any other remedy. All available
remedies are cumulative.

Section 6.04. Waiver of Existing Defaults.
              ---------------------------

     Subject to Section 9.02, the Holders of a majority in principal amount of
the outstanding Securities of a Series on behalf of all the Holders of the
Series by notice to the Trustee may waive an existing Default on such Series and
its consequences.  When a Default is waived, it is cured and stops continuing,
and any Event of Default arising therefrom shall be deemed to have been cured;
but no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereon.

Section 6.05. Control by Majority.
              -------------------

     The Holders of a majority in principal amount of the outstanding Securities
of a Series 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 it with respect to such Series.  The Trustee, however, may refuse
to follow any direction (i) that conflicts with law or this Indenture, (ii)
that, subject to Section 7.01, the Trustee determines is unduly prejudicial to
the rights of other Securityholders, or (iii) that would involve the Trustee in
personal liability.

Section 6.06. Limitation on Suits.
              -------------------

     A Securityholder of a Series may not pursue any remedy with respect to this
Indenture or the Series unless:

     (1)      the Holder gives to the Trustee written notice of a continuing
              Event of Default on the Series;

     (2)      the Holders of at least a majority in principal amount of the
              outstanding Securities of the Series make a written request to the
              Trustee to pursue the remedy;

     (3)      such Holder or Holders offer to the Trustee indemnity satisfactory
              to the Trustee against any loss, liability or expense;

     (4)      the Trustee does not comply with the request within 90 days after
              receipt of the request and the offer of indemnity; and

     (5)      no written request inconsistent with such written request shall
              have been given to the Trustee pursuant to this Section 6.06.

     A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

                                      21
<PAGE>

Section 6.07. Rights of Holders to Receive Payment.
              ------------------------------------

     Notwithstanding any other provision of this Indenture, the right of any
Holder to receive payment of principal of and interest on the Security, on or
after the respective due dates expressed in the Security, or to bring suit for
the enforcement of any such payment on or after such respective dates, is
absolute and unconditional and shall not be impaired or affected without the
consent of the Holder.

Section 6.08. Collection Suit by Trustee.
              --------------------------

     If an Event of Default in payment of interest or principal specified in
Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount of principal and interest remaining unpaid.

Section 6.09. Trustee May File Proofs of Claim.
              --------------------------------

     The Trustee may file such proofs of claim and 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 and counsel) and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property, and unless prohibited by applicable law or regulation, may vote on
behalf of the Holders in any election of a Custodian, and shall be entitled and
empowered to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same and any Custodian in
any such judicial proceeding is hereby authorized by each Securityholder to make
such payments to the Trustee.  Nothing herein shall be deemed to authorize the
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder or to authorize
the Trustee to vote in respect of the claim of any Securityholder except as
aforesaid for the election of the Custodian.

Section 6.10. Priorities.
              ----------

     If the Trustee collects any money pursuant to this Article, it shall pay
out the money in the following order:

     First:   to the Trustee for amounts due under Section 7.07;

     Second:  to holders of Senior Indebtedness to the extent required by
     Article 11;

     Third:   to Securityholders for amounts due and unpaid on the Securities
     for principal and interest, ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Securities for
     principal and interest, respectively; and

     Fourth:  to the Company as its interests may appear.

                                      22
<PAGE>

     The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.
              ---------------------

     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, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having the due regard to the merits and
good faith of the claims or defenses made by the party litigant.  This Section
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.07 or a suit by Holders of more than 10% in principal amount of the Series.


                                 ARTICLE SEVEN

                                    Trustee

Section 7.01. Duties of Trustee.
              -----------------

     (a)      If an Event of Default has occurred and is continuing, the Trustee
              shall, prior to the receipt of directions from the Holders of a
              majority in principal amount of the Securities, exercise its
              rights and powers and use the same degree of care and skill in
              their exercise as a prudent man would exercise or use under the
              circumstances in the conduct of his own affairs.

     (b)      Except during the continuance of an Event of Default:

              (1)  The Trustee need perform only those duties that are
                   specifically set forth in this Indenture and no others and no
                   implied covenants or obligations shall be read into this
                   Indenture against the Trustee.

              (2)  In the absence of bad faith on its part, the Trustee may
                   conclusively rely, as to the truth of the statements and the
                   correctness of the opinions expressed therein, upon
                   certificates or opinions furnished to the Trustee and
                   conforming to the requirements of his Indenture. The Trustee,
                   however, shall examine the certificates and opinions to
                   determine whether or not they conform to the requirements of
                   this Indenture but need not confirm or investigate the
                   accuracy of mathematical calculations or other facts or
                   matters stated herein.

     (c)      The Trustee may not be relieved from liability for its own
              negligent action, its own negligent failure to act or its own
              willful misconduct, except that:

                                      23
<PAGE>

              (1)  This paragraph does not limit the effect of paragraph (b) of
                   this Section.

              (2)  The Trustee shall not be liable for any error of judgment
                   made in good faith by a Trust Officer, unless it is proved
                   that the Trustee was negligent in ascertaining the pertinent
                   facts.

              (3)  The Trustee shall not be liable with respect to any action it
                   takes or omits to take in good faith in accordance with a
                   direction received by it pursuant to Section 6.05 or any
                   other direction of the Holders permitted hereunder.

     (d)      Every provision of this Indenture that in any way relates to the
              Trustee is subject to paragraphs (a), (b) and (c) of this Section.

     (e)      The Trustee may refuse to perform any duty or exercise any right
              or power unless it receives indemnity satisfactory to it against
              any loss, liability or expense.

     (f)      The Trustee shall not be liable for interest on any money received
              by it except as the Trustee may agree with the Company. Money held
              in trust by the Trustee need not be segregated from other funds
              except to the extent required by law.

     (g)      None of the provisions contained in this Indenture shall require
              the Trustee to expend or risk its own funds or otherwise incur
              financial liability in the performance of any of its duties or in
              the exercise of any of its rights or powers, if there shall be
              reasonable grounds for believing that the repayment of such funds
              or adequate indemnity against such liability is not reasonably
              assured to it.

Section 7.02. Rights of Trustee.
              -----------------

     Subject to Section 7.01:

     (a)      The Trustee may rely and shall be protected in acting or
              refraining from acting on any document, resolution, certificate,
              instrument, report, or direction believed by it to be genuine and
              to have been signed or presented by the proper person. The Trustee
              need not investigate any fact or matter stated in the document,
              resolution, certificate, instrument, report, or direction.

     (b)      Before the Trustee acts or refrains from acting, it may require an
              Officers' Certificate or an Opinion of Counsel or both, which
              shall conform to Sections 10.04 and 10.05 hereof and containing
              such other statements as the Trustee reasonably deems necessary to
              perform its duties hereunder. The Trustee shall not be liable for
              any action it takes or omits to take in good faith in reliance on
              the Officers' Certificate, Opinion of Counsel or any other
              direction of the Company permitted hereunder.

                                      24
<PAGE>

     (c)      The Trustee may act through agents and shall not be responsible
              for the misconduct or negligence of any agent appointed with due
              care.

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

     (e)      The Trustee may consult with counsel, and the written advice of
              such counsel or any Opinion of Counsel as to matters of law shall
              be full and complete authorization and protection in respect of
              any action taken, omitted or suffered by it hereunder in good
              faith and in accordance with the advice or opinion of such
              counsel.

     (f)      Unless otherwise specifically provided in the Indenture, any
              demand, request, direction or notice from the Company shall be
              sufficient if signed by an Officer of the Company.

     (g)      For all purposes under this Indenture, the Trustee shall not be
              deemed to have notice or knowledge of any Event of Default (other
              than under Section 6.01(1) or 6.01(2)) unless a Trust Officer
              assigned to and working in the Trustee's corporate trust office
              has actual knowledge thereof or unless written notice of any Event
              of Default is received by the Trustee at its address specified in
              Section 10.02 hereof and such notice references the Securities
              generally, the Company or this Indenture.

Section 7.03. Individual Rights of Trustee.
              ----------------------------

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or its Affiliates
with the same rights it would have if it were not Trustee.  Any Agent may do the
same with like rights.  The Trustee, however, must comply with Sections 7.10 and
7.11.

Section 7.04. Trustee's Disclaimer.
              --------------------

     The Trustee makes no representation as to the validity or adequacy of this
Indenture, the Securities or of any prospectus used to sell the Securities; it
shall not be accountable for the Company's use of the proceeds from the

Section 7.05. Notice of Defaults.
              ------------------

     If a Default on a Series occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Securityholder of the Series notice of
the Default (which shall specify any uncured Default known to it) within 90 days
after it occurs.  Except in the case of a default in payment of principal of or
interest on a Series, the Trustee may withhold the notice if and so long as the
board of directors of the Trustee, the executive or any trust committee of such
directors and/or responsible officers of the Trustee in good faith determine(s)
that withholding the notice is in the interests of Holders of the Series.

Section 7.06. Reports by Trustee to Holders.
              -----------------------------

     Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, the Trustee shall mail to each Securityholder a brief
report dated as of such May 15 that complies with TIA ss. 313(a) (but if no
event described in TIA ss. 313(2) has occurred within the twelve months
preceding the reporting date no report need be transmitted).  The Trustee also
shall comply with TIA ss. 313(b).

     A copy of each report at the time of its mailing to Securityholders shall
be delivered to the Company and filed by the Trustee with the SEC and each
national securities exchange on which the Securities are listed.  The Company
agrees to notify the Trustee of each national securities exchange on which the
Securities are listed.

Section 7.07. Compensation and Indemnity.
              --------------------------

     The Company shall pay to the Trustee or predecessor trustee from time to
time reasonable compensation for their respective services subject to any
written agreement between the Trustee and the Company.  The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it.  Such expenses shall include the reasonable compensation and
expenses of the Trustee's agents and counsel.  The Company shall indemnify the
Trustee and each predecessor trustee, its officers, directors, employees and
agents and hold it harmless against any loss, liability or expense incurred or
made by or on behalf of it in connection with the administration of this
Indenture or the trust hereunder and its duties hereunder including the costs
and expenses of defending itself against or investigating any claim in the
premises.  The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity.  The Company need not reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through the Trustee's, or
its officers', directors', employees' or agents' negligence or bad faith.

     To ensure the Company's payment obligations in this Section, the Trustee
shall have a claim prior to the Securities on all money or property held or
collected by the Trustee, except that held in trust to pay principal of or
interest on particular Securities.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 6.01 or in connection with Article 6
hereof, the expenses (including

                                      26
<PAGE>

the reasonable fees and expenses of its counsel) and the compensation for
services in connection therewith are to constitute expenses of administration
under any bankruptcy law.

Section 7.08. Replacement of Trustee.
              ----------------------

     The Trustee may resign by so notifying the Company.  The Holders of a
majority in principal amount of the outstanding Securities may remove the
Trustee by so notifying the removed Trustee in writing and may appoint a
successor trustee with the Company's consent. Such resignation or removal shall
not take effect until the appointment by the Securityholders or the Company as
hereinafter provided of a successor trustee and the acceptance of such
appointment by such successor trustee.  The Company may remove the Trustee and
any Securityholder may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor trustee for any or no
reason, including if:

     (1)      the Trustee fails to comply with Section 7.10 after written
              request by the Company or any bona fide Securityholder who has
              been a Securityholder for at least six months;

     (2)      the Trustee is adjudged a bankrupt or an insolvent;

     (3)      a receiver or other public officer takes charge of the Trustee or
              its property; or

     (4)      the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
trustee.  If a successor trustee does not take office within 45 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or any
Holder may petition any court of competent jurisdiction for the appointment of a
successor trustee.

     A successor trustee shall deliver a written  acceptance of its appointment
to the retiring Trustee and to the Company.  Immediately after that, the
retiring Trustee shall transfer all property held by it as Trustee to the
successor trustee, the resignation or removal of the retiring Trustee shall
become effective, and the successor trustee shall have all the rights, powers
and duties of the Trustee under this Indenture.  A successor trustee shall mail
notice of its succession to each Securityholder.

Section 7.09. Successor Trustee by Merger, etc.
              --------------------------------

transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor trustee.

Section 8.01. Defeasance Upon Deposit of Moneys or U.S. Government Obligations.
              ----------------------------------------------------------------

     (a)      The Company may, at its option and at any time, elect to have
              either paragraph (b) or paragraph (c) below be applied to the
              outstanding Securities of any Series upon compliance with the
              applicable conditions set forth in paragraph (d).

     (b)      Upon the Company's exercise under paragraph (a) of the option
              applicable to this paragraph (b), the Company shall be deemed to
              have been released and discharged from its respective obligations
              with respect to the outstanding Securities of a Series on the date
              the applicable conditions set forth below are satisfied
              (hereinafter, "Legal Defeasance"). For this purpose, such Legal
              Defeasance means that the Company shall be deemed to have paid and
              discharged the entire Indebtedness represented by the outstanding
              Securities of a Series, which shall thereafter be deemed to be
              "outstanding" only for the purposes of the Sections and matters
              under this Indenture referred to in (i) and (ii) below, and to
              have satisfied all its other obligations under such Securities and
              this Indenture insofar as such Securities are concerned, except
              for the following which shall survive until otherwise terminated
              or discharged hereunder: (i) the rights of Holders of outstanding
              Securities of a Series to receive solely from the trust fund
              described in paragraph (d) below and as more fully set forth in
              such paragraph, payments in respect of the principal of and
              interest on such Securities when such payments are due and (ii)
              obligations listed in Section 8.02, subject to compliance with
              this Section 8.01. The Company may exercise its option under this
              paragraph (b) notwithstanding the prior exercise of its option
              under paragraph (c) below with respect to such Securities.

                                      28
<PAGE>

     (c)      Upon the Company's exercise under paragraph (a) of the option
              applicable to this paragraph (c), the Company shall be released
              and discharged from the obligations under any covenant contained
              in Article Five and any other covenant contained in the
              Authorizing Resolution or supplemental indenture relating to such
              Series to the extent provided for therein, on and after the date
              the conditions set forth below are satisfied (hereinafter,
              "Covenant Defeasance"), and the Securities of such Series shall
              thereafter be deemed to be not "outstanding" for the purpose of
              any direction, waiver, consent or declaration or act of Holders
              (and the consequences of any thereof) in connection with such
              covenants, but shall continue to be deemed "outstanding" for all
              other purposes hereunder. For this purpose, such Covenant
              Defeasance means that, with respect to the outstanding Securities
              of a Series, 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 covenant, whether directly or indirectly, by
              reason of any reference elsewhere herein to any such covenant or
              by reason of any reference in any such 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 6.01(3), but, except as specified above, the remainder of
              this Indenture and such Securities shall be unaffected thereby.

     (d)      The following shall be the conditions to application of either
              paragraph (b) or paragraph (c) above to the outstanding Securities
              of the applicable Series:

              (1)  The Company shall have irrevocably deposited in trust with
                   the Trustee, pursuant to an irrevocable trust and security
                   agreement in form and substance reasonably satisfactory to
                   the Trustee, money in U.S. dollars or U.S. government
                   obligations or a combination thereof in such amounts and at
                   such times as are sufficient, in the opinion of a nationally
                   recognized firm of independent public accountants, to pay the
                   principal of and interest on the outstanding Securities of
                   such Series to maturity or redemption; provided, however,
                   that the Trustee (or other qualifying trustee) shall have
                   received an irrevocable written order from the Company
                   instructing the Trustee (or other qualifying trustee) to
                   apply such money or the proceeds of such U.S. government
                   obligations to said payments with respect to the Securities
                   of such Series to maturity or redemption;

              (2)  No Default or Event of Default shall have occurred and be
                   continuing on the date of such deposit;

              (3)  Such deposit will not result in a Default under this
                   Indenture or a breach or violation of, or constitute a
                   default under, any other material instrument or agreement to
                   which the Company or any of its Subsidiaries is a party or by
                   which it or any of their property is bound;

<PAGE>

              (4)  (i) In the event the Company elects paragraph (b) hereof, the
                   Company shall deliver to the Trustee an Opinion of Counsel in
                   the United States, in form and substance reasonably
                   satisfactory to the Trustee, to the effect that (A) the
                   Company has received from, or there has been published by,
                   the Internal Revenue Service a ruling or (B) since the Issue
                   Date pertaining to such Series, there has been a change in
                   the applicable federal income tax law, in either case to the
                   effect that, and based thereon such Opinion of Counsel shall
                   state that, or (ii) in the event the Company elects paragraph
                   (c) hereof, the Company shall deliver to the Trustee an
                   Opinion of Counsel in the United States, in form and
                   substance reasonably satisfactory to the Trustee, to the
                   effect that, in the case of clauses (i) and (ii), Holders of
                   the Securities of such Series will not recognize income, gain
                   or loss for United States federal income tax purposes as a
                   result of such deposit and the defeasance contemplated hereby
                   and will be subject to federal income tax in the same amounts
                   and in the same manner and at the same times as would have
                   been the case if such deposit and defeasance had not
                   occurred;

              (5)  The Company shall have delivered to the Trustee an Officers'
                   Certificate, stating that the deposit under clause (1) was
                   not made by the Company with the intent of preferring the
                   Holders of the Securities of such Series over any other
                   creditors of the Company or with the intent of defeating,
                   hindering, delaying or defrauding any other creditors of the
                   Company or others;

              (6)  The Company shall have delivered to the Trustee an Opinion of
                   Counsel, reasonably satisfactory to the Trustee, to the
                   effect that, (A) the trust funds will not be subject to the
                   rights of Holders of Indebtedness of the Company other than
                   the Securities of such Series and (B) assuming no intervening
                   bankruptcy of the Company between the date of deposit and the
                   91st day following the deposit and that no Holder of
                   Securities of such Series is an insider of the Company, after
                   the 91st day following the deposit, the trust funds will not
                   be subject to any applicable bankruptcy, insolvency,
                   reorganization or similar law affecting creditors' rights
                   generally; and

              (7)  The Company has delivered to the Trustee an Officers'
                   Certificate and an Opinion of Counsel, each stating that all
                   conditions precedent specified herein relating to the
                   defeasance contemplated by this Section 8.01 have been
                   complied with.

     In the event all or any portion of the Securities of a Series are to be
redeemed through such irrevocable trust, the Company must make arrangements
satisfactory to the Trustee, at the time of such deposit, for the giving of the
notice of such redemption or redemptions by the Trustee in the name and at the
expense of the Company.

     (e)      In addition to the Company's rights above under this Section 8.01,
              the Company may terminate all of its obligations under this
              Indenture with respect to a Series when:

              (1)  All Securities of such Series theretofore authenticated and
                   delivered (other than Securities which have been destroyed,
                   lost or stolen and which have been replaced or paid as
                   provided in Section 2.07 and Securities for whose payment
                   money has theretofore been deposited in trust or segregated
                   and held in trust by the Company and thereafter repaid to the
                   Company or discharged from such trust) have been delivered to
                   the Trustee for cancellation or all such Securities not
                   theretofore delivered to the Trustee for cancellation have
                   become due and payable and the Company has irrevocably
                   deposited or caused to be deposited with the Trustee as trust
                   funds in trust solely for that purpose an amount of money
                   sufficient to pay and discharge the entire Indebtedness on
                   the Securities not theretofore delivered to the Trustee for
                   cancellation, for principal of and interest;

              (2)  The Company has paid or caused to be paid all other sums
                   payable hereunder by the Company;

              (3)  The Company has delivered irrevocable instructions to the
                   Trustee to apply the deposited money toward the payment of
                   the Securities at maturity or redemption, as the case may be;
                   and

              (4)  The Company has delivered to the Trustee an Officers'
                   Certificate and an Opinion of Counsel, stating that all
                   conditions precedent specified herein relating to the
                   satisfaction and discharge of this Indenture have been
                   complied with.

Section 8.02. Survival of the Company's Obligations.
              -------------------------------------

     Notwithstanding the satisfaction and discharge of the Indenture under
Section 8.01, the Company's obligations in paragraph 9 of the Securities and
Sections 2.03 through 2.07, 4.01, 7.07, 7.08, 8.04 and 8.05, however, shall
survive until the Securities of an applicable Series are no longer outstanding.
Thereafter, the Company's obligations in paragraph 9 of the Securities of such
Series and Sections 7.07, 8.04 and 8.05 shall survive (as they relate to such
Series).

Section 8.03. Application of Trust Money.
              --------------------------

     The Trustee shall hold in trust money or U.S. government obligations
deposited with it pursuant to Section 8.01.  It shall apply the deposited money
and the money from U.S. government obligations in accordance with this Indenture
to the payment of principal of and interest on the Securities of the defeased
Series.

<PAGE>

Section 8.04. Repayment to the Company.
              ------------------------

     The Trustee and the Paying Agent shall promptly pay to the Company upon
request any excess money or securities held by them at any time.  The Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two
years; 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 a newspaper of general circulation in the City of New York
or mail to each such Holder 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, any unclaimed balance of such money then
remaining will be repaid to the Company.  After payment to the Company,
Securityholders entitled to the money must look to the Company for payment as
general creditors unless applicable abandoned property law designates another
person and all liability of the Trustee or such Paying Agent with respect to
such money shall cease.

Section 8.05. Reinstatement.
              -------------

     If the Trustee is unable to apply any money or U.S. government obligations
in accordance with Section 8.01 by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture and the Securities relating to the Series shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.01 until
such time as the Trustee is permitted to apply all such money or U.S. government
obligations in accordance with Section 8.01; provided, however, that (a) if the
Company has made any payment of interest on or principal of any Securities of
the Series because of the reinstatement of their obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. government obligations held by the Trustee and
(b) unless otherwise required by any legal proceeding or any order or judgment
of any court or governmental authority, the Trustee shall return all such money
or U.S. government obligations to the Company promptly after receiving a written
request therefor at any time, if such reinstatement of the Company's obligations
has occurred and continues to be in effect.

affected, however, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.04, may not:

     (1)      reduce the amount of Securities of such Series whose Holders must
              consent to an amendment, supplement or waiver;

     (2)      reduce the rate of or change the time for payment of interest,
              including defaulted interest, on any Security;

     (3)      reduce the principal of or change the fixed maturity of any
              Security or alter the provisions (including related definitions)
              with respect to redemption of Securities pursuant to Article Three
              hereof or with respect to any obligations on the part of the
              Company to offer to purchase or to redeem Securities of a Series
              pursuant to the Authorizing Resolution or supplemental indenture
              pertaining to such Series;

     (4)      modify the ranking or priority of the Securities of any Series;

     (5)      make any change in Sections 6.04, 6.07 or this Section 9.02;

     (6)      waive a continuing Default or Event of Default in the payment of
              the principal of or interest on any Security; or

                                      33
<PAGE>

     (7)      make any Security payable at a place or in money other than that
              stated in the Security, or impair the right of any Securityholder
              to bring suit as permitted by Section 6.07.

     An amendment of a provision included solely for the benefit of one or more
Series does not affect the interests of Securityholders of any other Series.

     It shall not be necessary for the consent of the Holders under this Section
to approve the particular form of any proposed supplement, but it shall be
sufficient if such consent approves the substance thereof.

     After the issuance of any Securities, an amendment under this Section or
under Section 9.01 may not make any change that adversely affects in any
material respect the rights under Article 11 of the holders of Senior
Indebtedness, unless such holders of Senior Indebtedness consent to the change.

Section 9.03. Compliance with Trust Indenture Act.
              -----------------------------------

     Every amendment to or supplement of this Indenture or the Securities shall
comply with the TIA as then in effect.

Section 9.04. Revocation and Effect of Consents.
              ---------------------------------

     A consent to an amendment, supplement or waiver by a Holder shall bind the
Holder and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent is not made on any Security. Subject to the following paragraph, any
such Holder or subsequent Holder, however, may revoke the consent as to his
Security or portion of a Security.  Such revocation shall be effective only if
the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders of Securities of any Series entitled to
consent to any amendment, supplement or waiver, which record date shall be at
least 10 days prior to the first solicitation of such consent.  If a record date
is fixed, then notwithstanding the last sentence of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date.  No such consent shall be valid or effective for more
than 90 days after such record date.

     After an amendment, supplement or waiver becomes effective, it shall bind
every Holder, unless it makes a change described in any of clauses (1) through
(7) of Section 9.02, in which case, the amendment, supplement or waiver shall
bind only each Holder of a Security who has consented to it and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security; provided, that any such waiver shall not

                                      34
<PAGE>

impair or affect the right of any Holder to receive payment of principal of and
interest on a Security, on or after the respective due dates expressed in such
Security, or to bring suit for the enforcement of any such payment on or after
such respective dates without the consent of such Holder.

Section 9.05.   Notation on or Exchange of Securities.
                -------------------------------------

     If an amendment, supplement or waiver changes the terms of a Security, the
Company may require the Holder of the Security to deliver it to the Trustee, at
which time the Trustee shall place an appropriate notation on the Security about
the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determines, the Company in exchange for the Security shall issue
and the Trustee shall authenticate a new Security that reflects the changed
terms.

Section 9.06.   Trustee to Sign Amendments, etc.
                -------------------------------

     Subject to Section 7.02(b), the Trustee shall sign any amendment,
supplement or waiver authorized pursuant to this Article if the amendment,
supplement or waiver does not adversely affect the rights, duties, liabilities
or immunities of the Trustee.  If it does, the Trustee may but need not sign it.
In signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive and shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel as conclusive evidence
that such amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms.

Section 11.01.  Agreement to Subordinate.
                ------------------------

     The Company agrees, and each Securityholder by accepting a Security agrees,
that the indebtedness evidenced by the Securities is subordinated in right of
payment, to the extent and in the manner provided in this Article, to the prior
payment in full of all Senior Indebtedness and that the subordination is for the
benefit of the holders of Senior Indebtedness.

                                      38
<PAGE>

Section 11.02.  Certain Definitions.
                -------------------

     "Representative" means the indenture trustee or other trustee, agent or
representative for an issue of Senior Indebtedness.

     "Senior Indebtedness" means all Indebtedness (present or future) created,
incurred, assumed or guaranteed by the Company (and all renewals, extensions or
refundings thereof), unless the instrument under which such Indebtedness is
created, incurred, assumed or guaranteed provides that such Indebtedness is not
senior or superior in right of payment to the Securities. Notwithstanding
anything to the contrary in the foregoing, Senior Indebtedness shall not include
(i) any  Indebtedness of the Company to any of its subsidiaries, (ii) any trade
payables of the Company or (iii) guarantees by the Company or any of its
Subsidiaries of Indebtedness (a) outstanding at the date hereof or (b) which may
be outstanding in the future, except that Senior Indebtedness shall include any
guarantees as may be listed in a supplemental indenture and any other present
and future guarantees that provide by their terms that they constitute Senior
Indebtedness.

Section 11.03.  Liquidation; Dissolution; Bankruptcy.
                ------------------------------------

     Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its Property:

     (1)        holders of Senior Indebtedness shall be entitled to receive
                payment in full in cash of the principal of and interest
                (including interest accruing after the commencement of any such
                proceeding) to the date of payment on the Senior Indebtedness
                before Securityholders shall be entitled to receive any payment
                of principal of or interest on Securities; and

     (2)        until the Senior Indebtedness is paid in full in cash, any
                distribution to which Securityholders would be entitled but for
                this Article shall be made to holders of Senior Indebtedness as
                their interests may appear, except that Securityholders may
                receive securities that are subordinated to Senior Indebtedness
                to at least the same extent as the Securities.

     For purposes of this Article 11, a distribution may consist of cash,
securities or other property, by set-off or otherwise.

Section 11.04.  Default on Senior Indebtedness.
                ------------------------------

     Upon the final maturity of any Senior Indebtedness by lapse of time,
acceleration or otherwise, all such Senior Indebtedness shall first be paid in
full, or such payment duly provided for in cash or in a manner satisfactory to
the holders of such Senior Indebtedness, before any payment is made by the
Company or any person acting on behalf of the Company on account of the
principal or interest of the Securities.

                                      39
<PAGE>

     The Company may not pay principal of or interest on the Securities and may
not acquire any Securities for cash or property (other than capital stock of the
Company or other securities of the Company that are subordinated to Senior
Indebtedness to at least the same extent as the Securities) if a default on
Senior Indebtedness occurs and is continuing that permits holders of such Senior
Indebtedness to accelerate its maturity.

     The Company shall resume payments on the Securities and may acquire them,
if this Article otherwise permits the payment or acquisition at that time, when
the default is cured or waived.

Section 11.05.  Acceleration of Securities.
                --------------------------

     If payment of the Securities is accelerated because of an Event of Default,
the Company shall promptly notify holders of Senior Indebtedness of the
acceleration.  The Company shall pay the Securities when 180 days pass after the
acceleration occurs if this Article permits the payment at that time; provided,
however, that if no Senior Indebtedness is outstanding at the time of such
acceleration, the Company shall pay the Securities in accordance with the
provisions of Article 6.

Section 11.06.  When Distributions Must Be Paid Over.
                ------------------------------------

     In the event that the Company shall make any payment to the Trustee on
account of the principal or interest on the Securities at a time when such
payment is prohibited by Section 11.03 or 11.04, such payment shall be held by
the Trustee in trust for the benefit of, and shall forthwith be paid over and
delivered to, the holders of Senior Indebtedness (pro rata as to each of such
holders on the basis of the respective amounts of Senior Indebtedness held by
them) or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Indebtedness may have been issued, as their respective
interests may appear, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to pay all Senior Indebtedness in full
in accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

     If a distribution is made to Securityholders that because of this Article
should not have been made to them, the Securityholders who receive the
distribution shall hold it in trust for holders of Senior Indebtedness and pay
it over to them as their interests may appear.

Section 11.07.  Notice by the Company.
                ---------------------

     The Company shall promptly notify the Trustee and the Paying Agent of any
facts known to the Company that would cause a payment of principal of or
interest on the Securities to violate this Article, but failure to give such
notice shall not affect the subordination of the Securities to the Senior
Indebtedness provided in this Article.  Nothing in this Article shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 7.07.

                                      40
<PAGE>

Section 11.08.  Subrogation.
                -----------

     After all Senior Indebtedness is paid in full and until the Securities are
paid in full, Securityholders shall be subrogated to the rights of holders of
Senior  Indebtedness  to receive distributions  applicable to Senior
Indebtedness to the extent that distributions  otherwise payable to the
Securityholders have been applied to the payment of Senior Indebtedness.  A
distribution made under this Article to holders of Senior Indebtedness which
otherwise would have been made to Securityholders is not, as between the Company
and Securityholders, a payment by the Company on Senior Indebtedness.

Section 11.09.  Relative Rights.
                ---------------

     This Article defines the relative rights of Securityholders and holders of
Senior Indebtedness.  Nothing in this Indenture shall:  (1) impair, as between
the Company and Securityholders, the obligation of the Company, which is
absolute and unconditional, to pay principal of and interest on the Securities
in accordance with their terms;

     (2)        affect the relative rights of Securityholders and creditors of
                the Company, other than holders of Senior Indebtedness; or

     (3)        prevent the Trustee or any Securityholder from exercising its
                available remedies upon a Default or Event of Default, subject
                to the rights of holders of Senior Indebtedness to receive
                distributions otherwise payable to Securityholders.

     If the Company fails to pay principal of or interest on a Security on the
due date because of this Article, the failure is still a Default or Event of
Default.

Section 11.10.  Subordination May Not Be Impaired by the Company.
                ------------------------------------------------

     No right of any holder of Senior  Indebtedness to enforce the subordination
of the indebtedness evidenced by the Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

Section 11.11.  Distribution or Notice to the Representative.
                --------------------------------------------

     Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness pursuant to this Article 11, the distribution may be made
and the notice given to their Representative.

Section 11.12.  Rights of the Trustee and Paying Agent.
                --------------------------------------

     Notwithstanding any provision of this Article 11 or any other provision of
this Indenture, the Trustee and Paying Agent shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee or a Paying Agent or the taking of any other
action (pursuant to this Article 11) by the Trustee or a Paying Agent

                                      41
<PAGE>

unless and until the Trustee or such Paying Agent, as the case may be, shall
have received at its office specified in Section 10.02 written notice thereof
from the Company, a Representative or a holder of Senior Indebtedness and, prior
to the receipt of any such written notice, the Trustee, subject to the
provisions of Sections 7.01 and 7.02, and such Paying Agent, shall be entitled
in all respects conclusively to assume that no such facts exist. The Trustee or
Paying Agent may continue to make payments on the Securities unless it receives
such a notice at least three business days prior to the date upon which payment
is due.

     The Trustee shall be entitled to rely reasonably in good faith on the
delivery to it of a written notice by a person representing himself, herself or
itself to be a Representative or a holder of Senior Indebtedness to establish
that such notice has been given by a Representative or a holder of such Senior
Indebtedness.  Only the Company, a Representative or a holder of Senior
Indebtedness that has no Representative may give the notice.

     In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article 11, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee 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 11, and if such evidence is not furnished, the
Trustee 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.

     Upon any payment or distribution of assets of the Company referred to in
this Article 11, the Trustee 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 11.

     The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee.  Any
Agent may do the same with like rights.

Section 11.13.  No Fiduciary Duty to Holders of Senior Indebtedness.
                ---------------------------------------------------

     With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 11, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee or Paying Agent.  Neither the Trustee
nor the Paying Agent shall be deemed to owe any fiduciary duty to the holders of
such Senior

                                      42
<PAGE>

Indebtedness and, subject to the provisions of Section 7.02, the Trustee shall
not be liable to any holder of such Senior Indebtedness if it shall, in the
absence of bad faith, pay over or deliver to holders of Securities, the Company
or any other person monies or assets to which any holder of such Senior
Indebtedness shall be entitled by virtue of this Article 11 or otherwise.

     IN WITNESS WHEREOF, the parties have caused this Indenture to be duly

Re: Key Production Company, Inc. Form S-3 Registration Statement

Ladies and Gentlemen:

     As counsel for Key Production Company, Inc., a Delaware corporation
(the"Company"), we are familiar with Key's Registration Statement on Form S-3
(the "Registration Statement") filed with the Securities and Exchange Commission
(the "SEC") under the Securities Act of 1933 (as amended, the "Act"), File No.
_________, with respect to the offering and issuance from time to time by Key of
up to $150,000,000 aggregate offering price of the following: (i) one or more
series of its debt securities (the "Debt Securities"), (ii) shares of its
Preferred Stock (the "Preferred Stock"), or (iii) shares of its Common Stock,
par value $.25 per share (the "Common Stock").

     All capitalized terms which are not defined herein shall have the meanings
assigned to them in the Registration Statement.

     In connection with our examination of documents as hereinafter described,
we have assumed the genuineness of all signatures on, and the authenticity of,
all documents submitted to us as originals and the conformity to original
documents of all documents submitted to us as copies. With respect to agreements
and instruments executed by natural persons, we have assumed the legal
competency of such persons.

     For the purpose of rendering this opinion, we have made such factual and
legal examination as we deemed necessary under the circumstances, and in that
connection we have examined, among other things, originals or copies of the
following:

     (1) The Certificate of Incorporation of Key, as amended to date;

     (2) The Bylaws of Key, as amended to date;

     (3) The Form of Senior Indenture (and form of notes) filed as an exhibit to
         the Registration Statement;

     (4) The Form of Senior Subordinated Indenture (and form of notes) filed as
         an exhibit to the Registration Statement;

     (5) The Form of Junior Subordinated Indenture (and form of notes) filed as
         an exhibit to the Registration Statement;

     (6) Such records of the corporate proceedings of Key, and such other
         documents that we considered necessary or appropriate for the purpose
         of rendering this opinion; and

     (7) Such other certificates and assurances from public officials, officers
         and representatives of Key that we considered necessary or appropriate
         for the purpose of rendering this opinion.

<PAGE>

     On the basis of the foregoing examination, and in reliance thereon, we are
of the opinion that (subject to compliance with the pertinent provisions of the
Act and, with respect to the Indentures (as defined below) and the Debt
Securities, the Trust Indenture Act of 1939, as amended, and to compliance with
such securities or "blue sky" laws of any jurisdiction as may be applicable):

     1.  When (a) the Debt Securities in substantially the form contained in (as
appropriate) the Form of Senior Indenture, the Form of Senior Subordinated
Indenture or the Form of Junior Subordinated Indenture (as amended or
supplemented in accordance with the respective terms thereof, each an
"Indenture") shall have been authorized, executed and authenticated in
accordance with the terms of the applicable Indenture, (b) the Indentures shall
have been qualified under the Trust Indenture Act of 1939, duly executed and
delivered and (c) the Debt Securities shall have been issued and sold as
described in the Registration Statement, and if in an underwritten offering, in
accordance with the terms and conditions of the applicable underwriting
agreement, and in a manner contemplated in the Registration Statement, including
the Prospectus Supplement relating to any such Debt Securities, the Debt
Securities will be duly authorized and valid and binding obligations of Key,
subject to the effect of any bankruptcy, insolvency, reorganization, moratorium,
arrangement, or similar laws affecting the enforcement of creditors' rights
generally (including, without limitation, the effect of statutory or other laws
regarding fraudulent transfers or preferential transfers) and general principles
of equity, regardless of whether enforceability is considered in a proceeding in
equity or at law.

     2.  When the Preferred Stock shall have been authorized, issued and sold as
described in the Registration Statement, and if in an underwritten offering, in
accordance with the terms and conditions of the applicable underwriting
agreement, and in a manner contemplated in the Registration Statement, including
the Prospectus Supplement relating to the applicable series of such Preferred
Stock, the Preferred Stock will be validly issued, fully paid and nonassessable.

     3.  When the Common Stock shall have been authorized, issued and sold as
described in the Registration Statement, and if in an underwritten offering, in
accordance with the terms and conditions of the applicable underwriting
agreement, and in a manner contemplated in the Registration Statement, including
the Prospectus Supplement relating to the applicable offering of such Common
Stock, the Common Stock will be validly issued, fully paid and nonassessable.

     This opinion is limited to the present corporate laws of the State of
Delaware, the present laws of the States of Colorado and New York and the
present federal laws of the United States and to the present judicial
interpretations thereof and to the facts as they presently exist. We undertake
no obligation to advise you as a result of developments occurring after the date
hereof or as a result of facts or circumstances brought to our attention after
the date hereof.

     This opinion may be filed as an exhibit to the Registration Statement.
Consent is also given to the reference to this firm under the caption "Legal
Matters" in the prospectus contained in the Registration Statement. In giving
this consent, we do not admit we are included in the category of persons whose
consent is required under Section 7 of the Act or the rules and regulations of
the SEC promulgated thereunder.

Very truly yours,
