Prospectus

NUEVO ENERGY COMPANY

Debt Securities, Preferred Stock,
Common Stock and Warrants

NUEVO FINANCING I

Trust Preferred Securities Fully and Unconditionally Guaranteed by Nuevo Energy
Company

Nuevo Energy Company ("Nuevo" or the "Company") may offer and issue from time to
time, together or separately, (i) its debt securities (the "Debt Securities"),
which may be senior or senior subordinated debt securities (the "Senior Debt
Securities") or subordinated debt securities (the "Subordinated Debt
Securities"), consisting of notes, debentures or other secured or unsecured
evidences of indebtedness in one or more series; (ii) its preferred shares,
$1.00 par value per share (the "Preferred Stock"); and (iii) warrants to
purchase Debt Securities or Preferred Stock or Common Stock or any combination
thereof, as shall be designated by the Company at the time of the offering (the
"Warrants") in amounts, at prices and on terms to be determined at the time of
the offering.  Any shares of its common stock, $.01 par value per share ("Common
Stock"), issued by Nuevo hereunder will be issued only upon conversion of, or in
exchange for, other securities, and no Common Stock will be issued by Nuevo in a
primary offering.  Certain Selling Stockholders identified under "Selling
Stockholders" herein may sell up to 2,138,605 shares of Common Stock, in
amounts, at prices and on terms to be determined at the time of the offering.

Nuevo Financing I (the "Nuevo Trust"), a statutory business trust created under
the laws of the State of Delaware, may offer, from time to time, preferred
securities, representing undivided beneficial interests in the assets of the
Nuevo Trust ("Trust Preferred Securities").  Trust Preferred Securities may also
be issuable upon exchange for shares of Preferred Stock issued by the Company.
The payment of periodic cash distributions ("distributions") with respect to
Trust Preferred Securities out of moneys held by the Nuevo Trust, and payment on
liquidation, redemption or otherwise with respect to such Trust Preferred
Securities, will be guaranteed by the Company to the extent described herein
(the  "Trust Preferred Securities Guarantee"). See "Description Of Trust
Preferred Securities Guarantee." The Company's obligations under the Trust
Preferred Securities Guarantee will be subordinate and junior in right to all
other liabilities of the Company and rank pari passu with the most senior
preferred stock, if any, issued from time to time by the Company.  A series of
Subordinated Debt Securities may be issued and sold to the Nuevo Trust, or a
trustee of the Nuevo Trust, in connection with the investment of the proceeds
from the offering of Trust Preferred Securities and Trust Common Securities (as
defined herein, together the "Trust Securities") of the Nuevo Trust. The
Subordinated Debt Securities purchased by the Nuevo Trust may be subsequently
distributed pro rata to holders of Trust Preferred Securities and Trust Common
Securities in connection with the dissolution of the Nuevo Trust upon the
occurrence of certain events as may be described in an accompanying supplement
to this Prospectus (a "Prospectus Supplement"). The Trust Preferred Securities
Guarantee, when taken together with the Company's other obligations under the
Subordinated Debt Securities, the Indenture related thereto and the Declaration
(as defined below), including its obligations to pay costs, expenses, debts and
liabilities of the Nuevo Trust (other than with respect to the Trust
Securities), will provide a full and unconditional guarantee on a subordinated
basis by the Company of payments due on the Trust Preferred Securities. The Debt
Securities, Preferred Stock, Common Stock, Warrants, Trust Preferred Securities
and Trust Preferred Securities Guarantees are collectively called the
"Securities."

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED ON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

_____________, 1996

The Securities to be sold by the Company and/or the Nuevo Trust may be offered
as separate series or issuances at an aggregate initial public offering price
not to exceed $150,000,000 or, if applicable, the equivalent thereof in one or
more foreign currencies, currency units, composite currencies or in amounts
determined by reference to an index as shall be designated by the Company, in

at the time of sale and set forth in the applicable Prospectus Supplement.  The
Prospectus Supplement relating to any series of Securities will contain
information concerning United States federal income tax considerations, if
applicable.

Unless otherwise specified in a Prospectus Supplement, the Senior Debt
Securities, when issued, will be unsecured and will rank on a parity with all
other unsubordinated indebtedness of the Company or, alternatively, will rank on
a parity with all other senior subordinated indebtedness of the Company. The
Subordinated Debt Securities, when issued, will be subordinated in right of
payment to all Senior Indebtedness (as hereinafter defined) of the Company
including any Senior Debt Securities.  If the Debt Securities are secured, the
security, which may consist of oil and gas properties or other assets owned by
the Company, and any related mortgage will be described in the Prospectus
Supplement.

Certain specific terms of the particular Securities in respect of which this
Prospectus is being delivered will be set forth in the applicable Prospectus
Supplement, including, where applicable, (i) in the case of Debt Securities, the
title, aggregate principal amount, denominations, maturity, subordination terms,
if any, any interest rate (which may be fixed or variable) and time of payment
of any interest, the right of the Company, if any, to defer payment of interest
on the Debt Securities and the maximum length of such deferral period, any terms
for redemption at the option of the Company or the holder, any terms for sinking
fund payments, any terms for conversion or exchange into other Securities,
currency or currencies of denomination and payment, if other than U.S. dollars,
any security applicable to Debt Securities which are secured, any listing on a
securities exchange and any other terms in connection with the offering and sale
of the Debt Securities in respect of which this Prospectus is delivered, as well

exchange, distribution rate (or method of calculation thereof), dates on which
distributions shall be payable and dates from which distributions shall accrue,
any voting rights, terms for any conversion or exchange into other Securities,
any redemption, exchange or sinking fund provisions, any other rights,
preferences, privileges, limitations or restrictions relating to the Trust
Preferred Securities and the terms upon which the proceeds of the sale of the
Trust Preferred Securities shall be used to purchase a specific series of
Subordinated Debt Securities of the Company, (iii) in the case of Preferred
Stock, the specific title, the aggregate amount, any dividend (including the
method of calculating payment of dividends), seniority, liquidation, redemption,
voting and other rights, any terms for any conversion or exchange into other
Securities, including Trust Preferred Securities, any listing on a securities
exchange, the initial public offering price and any other terms; and (iv) in the
case of Common Stock, the number of shares of Common Stock, the identity of the
Selling Stockholder and the terms of offering thereof.

exchange.  Any shares of Common Stock issuable upon conversion of any Trust
Preferred Securities, Debt Securities or Preferred Stock will also be listed on
such exchange, subject to official notice of issuance.

The Company, the Selling Stockholders and/or the Nuevo Trust may sell the
Securities directly, through agents, underwriters or dealers as designated from
time to time, or through a combination of such methods. See "Plan Of
Distribution."  If agents of the Company, the Selling Stockholders and/or the
Nuevo Trust or any dealers or underwriters are involved in the sale of the
Securities in respect of which this Prospectus is being delivered, the names of
such agents, dealers or underwriters and any applicable commissions or discounts
will be set forth in or may be calculated from the Prospectus Supplement with
respect to such Securities.  The net proceeds to the Company from such sale also
will be set forth in the applicable Prospectus Supplement.

This Prospectus may not be used to consummate sales of Securities unless
accompanied by a Prospectus Supplement.

IN CONNECTION WITH AN UNDERWRITTEN OFFERING, THE UNDERWRITERS FOR SUCH OFFERING
MAY OVER-ALLOT OR EFFECT TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET

representations other than those contained in this Prospectus, any accompanying
Prospectus Supplement or the documents incorporated or deemed incorporated by
reference herein, and, if given or made, such information or representations
must not be relied upon as having been authorized by the Company, the Nuevo
Trust or by any underwriter, agent or dealer. This Prospectus and any Prospectus
Supplement shall not constitute an offer to sell or a solicitation of an offer
to buy any of the Securities offered hereby in any jurisdiction to any person to
whom it is unlawful to make such offer or solicitation in such jurisdiction.
Neither the delivery of this Prospectus and any Prospectus Supplement nor any
sale made thereunder shall, under any circumstances, create any implication that
the information therein is correct as of any time subsequent to the date

Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the

The Company and the Nuevo Trust have filed a registration statement on Form S-3
(together with all amendments thereto, the "Registration Statement") under the
Securities Act of 1933, as amended (the "Securities Act").  This Prospectus does
not contain all of the information set forth in the Registration Statement,
certain parts of which are omitted in accordance with the rules and regulations
of the Commission.  For further information, reference is made to the
Registration Statement and the exhibits filed as part thereof.  Statements
contained herein are qualified in their entirety by reference to the
Registration Statement and such exhibits.

No separate financial statements of the Nuevo Trust have been included herein.
The Company does not consider that such financial statements would be material
to holders of the Trust Preferred Securities because (i) all of the voting
securities of the Nuevo Trust will be owned, directly or indirectly, by the
Company, a reporting company under the Exchange Act, (ii) the Nuevo Trust has no
independent operations but exists for the sole purpose of issuing securities
representing undivided beneficial interests in the assets of the Nuevo Trust and
investing the proceeds thereof in Subordinated Debt Securities issued by the
Company, and (iii) the Company's obligations described herein and in any
accompanying Prospectus Supplement under the Declaration of the Nuevo Trust, the
guarantee issued with respect to Trust Preferred Securities issued by that
Trust, the Subordinated Debt Securities purchased by that Trust and the related
Indenture, taken together, constitute a full and unconditional guarantee of
payments due on the Trust Preferred Securities.  See "Description Of Debt
Securities" and "Description Of Trust Preferred Securities Guarantees."

The Nuevo Trust is not currently subject to the information reporting
requirements of the Exchange Act.  The Nuevo Trust will become subject to such
requirements upon the effectiveness of the Registration Statement, although it
intends to seek and expects to receive exemptions therefrom.

                                  THE COMPANY

Nuevo is a Houston, Texas based company engaged in the exploitation, exploration
and acquisition of crude oil and natural gas properties. The Company's
properties are located domestically onshore and offshore California, in East
Texas and the onshore Gulf Coast region, and internationally in waters offshore
the Republic of Congo.

                                THE NUEVO TRUST

Nuevo Financing I is a statutory business trust created under Delaware law
pursuant to (i) a separate declaration of trust (as amended, the "Declaration")
executed by the Company, as sponsor for the trust (the "Sponsor") and the Nuevo
Trustees (as defined herein) for the trust and (ii) the filing of a certificate
of trust with the Delaware Secretary of State on November 15, 1996. The Nuevo
Trust exists for the exclusive purposes of (i) issuing the Trust Preferred
Securities and common securities representing undivided beneficial interests in
the assets of the Trust (the "Trust Common Securities" and, together with the
Trust Preferred Securities, the "Trust Securities"), (ii) investing the gross
proceeds of the Trust Securities in a specific series of Subordinated Debt
Securities and (iii) engaging in only those other activities necessary or
incidental thereto. All of the Trust Common Securities will be directly or
indirectly owned by the Company.  The Trust Common Securities will rank pari
passu, and payments will be made thereon pro rata, with the Trust Preferred
Securities except that upon an event of default under the Declaration, the
rights of the holders of the Trust Common Securities to payment in respect of
distributions and payments upon liquidation, redemption and otherwise will be
subordinated to the rights of the holders of the Trust Preferred Securities.
The Company will, directly or indirectly, acquire Trust Common Securities in an
aggregate liquidation amount equal to 3% of the total capital of the Nuevo
Trust. The Nuevo Trust has a term of approximately 35 years, but may earlier
terminate as provided in the Declaration. The Nuevo Trust's business and affairs
will be conducted by the trustees (the "Nuevo Trustees") appointed by the
Company, as the direct or indirect holder of all the Trust Common Securities.
Except in certain limited circumstances, the holder of the Trust Common
Securities will be entitled to appoint, remove or replace any of, or increase or
reduce the number of, the Nuevo Trustees. The duties and obligations of the
Nuevo Trustees shall be governed by the Declaration of the Nuevo Trust.  A
majority of the Nuevo Trustees (the "Regular Trustees") will be persons who are
employees or officers of or affiliated with the Company.  One Nuevo Trustee will
be a financial institution which will be unaffiliated with the Company and which
shall act as property trustee and as indenture trustee for purposes of the Trust
Indenture Act of 1939 , as amended (the "Trust Indenture Act"), pursuant to the
terms set forth in a Prospectus Supplement (the "Property Trustee"). In
addition, unless the Property Trustee maintains a principal place of business in
the State of Delaware, and otherwise meets the requirements of applicable law,
one Nuevo Trustee will have its principal place of business or reside in the
State of Delaware (the "Delaware Trustee").  The Company will pay all fees and
expenses related to the Nuevo Trust and the offering of Trust Securities.  The
payment of periodic distributions with respect to the Trust Preferred Securities
out of moneys held by the Nuevo Trust, and payment on liquidation, redemption or
otherwise with respect to the Trust Preferred Securities, will be guaranteed by
the Company to the extent described herein. See "Description Of Trust Preferred
Securities Guarantee." The Company's obligations under the Trust Preferred
Securities Guarantee will be subordinate and junior in right of payment to all
other liabilities of the Company and rank pari passu with the most senior
preferred shares, if any, issued from time to time by the Company.  The office
of the Delaware Trustee for the Nuevo Trust in the State of Delaware is c/o
Wilmington Trust Company, Rodney Square North, 1100 North Market Street,
Wilmington, Delaware 19890-0001. The principal place of business of the Nuevo

                         DESCRIPTION OF DEBT SECURITIES

The Senior Debt Securities will be issued under an indenture (the "Senior
Indenture") between the Company and a trustee (the "Senior Indenture Trustee");
and the Subordinated Debt Securities are to be issued under a subordinated
indenture ("Subordinated Indenture") between the Company and Wilmington Trust
Company, as trustee (the "Subordinated Indenture Trustee"). The Senior Indenture
and the Subordinated Indenture are sometimes referred to herein collectively as
the "Indentures" or, individually, as an "Indenture." The form of the
Subordinated Indenture has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part or incorporated therein by
reference. The Senior Indenture permits the Company and the Senior Indenture
Trustee, and the Subordinated Indenture permits the Company and the Subordinated
Indenture Trustee, to enter into a Supplemental Indenture to provide for the
appointment of another qualifying bank or trust company to act as trustee with
respect to a series of Senior Debt Securities or Subordinated Debt Securities,
respectively. Any such bank or trust company so appointed will be identified in
the Prospectus Supplement relating to the particular Debt Securities offered
thereby (the "Offered Debt Securities"). The Senior Indenture Trustee and the
Subordinated Indenture Trustee, as well as any such other bank or trust company
as shall have been appointed to act with respect to a series of Offered Debt
Securities, are sometimes referred to herein collectively as the "Trustees" or
individually as a "Trustee."

The Debt Securities will represent unsecured general obligations of the Company,
unless otherwise provided in the Prospectus Supplement, with the relative
rankings indicated in the applicable Prospectus Supplement.

The following summaries of certain provisions of the Debt Securities and the
Indentures do not purport to be complete and are subject to and are qualified in
their entirety by reference to all the provisions of the Indenture applicable to
a particular series of Offered Debt Securities (the "Applicable Indenture"),
including the definitions of certain terms therein.  Wherever particular
Sections, Articles or defined terms of the Applicable Indenture are referred to,
it is intended that such Sections, Articles or defined terms shall be
incorporated herein by reference.  Article and Section references used herein
are references to the 

                                       5
<PAGE>
 
Applicable Indenture or the Indentures, as the case may be. Capitalized terms
not otherwise defined herein shall have the respective meanings given to them in
the Applicable Indenture.

In the event Subordinated Debt Securities are issued to the Nuevo Trust or a
trustee of such trust in connection with the issuance of Trust Securities by the
Nuevo Trust, such Subordinated Debt Securities will be issued pursuant to the
Subordinated Indenture and subsequently may be distributed pro rata to the
holders of such Trust Securities in connection with the dissolution of the Nuevo
Trust upon the occurrence of certain events described in the Prospectus
Supplement relating to such Trust Securities. Only one series of Subordinated
Debt Securities will be issued to the Nuevo Trust or a trustee of such trust in
connection with the issuance of Trust Securities by the Nuevo Trust.

The following description sets forth certain general terms and provisions of the
Debt Securities to which any Prospectus Supplement may relate.  The particular
terms of the Offered Debt Securities and the extent, if any, to which such
general provisions may not apply to the Offered Debt Securities will be
described in the Prospectus Supplement relating to such Offered Debt Securities.

respect to the Offered Debt Securities in addition to those provided in the

<PAGE>
 
described under "Defeasance and Covenant Defeasance"; (20) any authenticating or

the Offered Debt Securities; (21) designation (including whether the Offered
Debt Securities are senior debt, senior subordinated debt or subordinated debt
and whether such debt is convertible); (22) the terms, if any, on which such
Offered Debt Securities will be subordinate to other debt of the Company; (23)

Unless otherwise indicated in the Prospectus Supplement relating thereto, the
Offered Debt Securities are to be issued as registered securities without
coupons in denominations of $1,000 or any integral multiple of $1,000. (Section
302).  No service charge will be made for any transfer or exchange of such
Offered Debt Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.
(Section 305)

Debt Securities may be issued under the Indentures as Original Issue Discount
Debt Securities to be offered and sold at a substantial discount below their
stated principal amount. Special Federal income tax, accounting and other
considerations applicable thereto will be described in the Prospectus Supplement
relating thereto. "Original Issue Discount Debt Security" means any security
which provides for an amount less than the principal amount thereof to be due
and payable upon the declaration of acceleration of the maturity thereof upon
the occurrence and continuance of an Event of Default. (Section 101)

If the Debt Securities are denominated in whole or in part in any currency other
than United States dollars, if the principal of (and premium, if any) or
interest, if any, on the Debt Securities is to be payable, at the election of
the Company or a Holder thereof, in a currency or currencies other than that in
which such Debt Securities are to be payable, or if any index is used to
determine the amount of payments of principal of, premium, if any, or interest
on any series of the Debt Securities, special Federal income tax, accounting and
other considerations applicable thereto will be described in the Prospectus
Supplement relating thereto.

PAYMENT AND PAYING AGENTS

Unless otherwise indicated in the applicable Prospectus Supplement, payment of
interest on a Debt Security on any Interest Payment Date will be made to the
Person in whose name such Debt Security (or one or more Predecessor Debt
Securities) is registered at the close of business on the Regular Record Date
for such interest payment. (Section 307)

Unless otherwise indicated in the applicable Prospectus Supplement, principal of
and any premium and interest on the Debt Securities of a particular series will
be payable at the office of such Paying Agent or Paying Agents as the Company
may designate for such purpose from time to time, except that, at the option of
the Company, payment of any interest may be made by check mailed to the address
of the Person entitled thereto as such address appears in the Security Register.
Unless otherwise indicated in the applicable Prospectus Supplement, the
corporate trust office of the applicable Trustee in New York, New York will be
designated as the Company's sole Paying Agent for payments with respect to Debt
Securities of each series.

Any other Paying Agents initially designated by the Company for the Debt
Securities of a particular series will be named in the applicable Prospectus
Supplement. The Company may at any time designate additional Paying Agents or
rescind the designation of any Paying Agent or approve a change in the office
through which any Paying Agent acts, except that the Company will be required to
maintain a Paying Agent in each place of payment for the Debt Securities of a
particular series. (Section 1002)

All moneys paid by the Company to a Paying Agent for the payment of the
principal of or any premium or interest on any Debt Security which remain
unclaimed at the end of two years after such principal, premium or interest has
become due and payable will be repaid to the Company, and the Holder of such
Debt Security thereafter may look only to the Company for payment thereof.
(Section 1003)

SUBORDINATION OF SUBORDINATED DEBT SECURITIES

Unless otherwise indicated in the Prospectus Supplement, the following
provisions will apply to the Subordinated Debt Securities.

The Subordinated Debt Securities will, to the extent set forth in the
Subordinated Indenture, be subordinate in right of payment to the prior payment
in full of all Senior Indebtedness. Upon any payment 

                                       7
<PAGE>
 
or distribution of assets to creditors upon any liquidation, dissolution,
winding up, reorganization, assignment for the benefit of creditors, marshaling
of assets or any bankruptcy, insolvency, debt restructuring or similar
proceedings in connection with any insolvency or bankruptcy proceeding of the
Company the holders of Senior Indebtedness will first be entitled to receive
payment in full of principal of (and premium, if any) and interest, if any, on
such Senior Indebtedness before the holders of the Subordinated Debt Securities
will be entitled to receive or retain any payment in respect of the principal of
(and premium, if any) or interest, if any, on the Subordinated Debt Securities.
(Subordinated Indenture Section 1502)

By reason of such subordination, in the event of liquidation or insolvency,
Holders of Subordinated Debt Securities may recover less, ratably, than holders
of Senior Indebtedness and holders of Senior Indebtedness may recover more,
ratably, than the holders of the Subordinated Debt Securities. With respect to
any series of Subordinated Debt Securities, Senior Indebtedness may include
Indebtedness which is senior to such Subordinated Debt Securities and
subordinated to other Senior Indebtedness and obligations of the Company.

In the event of the acceleration of the maturity of any Subordinated Debt
Securities, the holders of all Senior Indebtedness (including any Senior
Subordinated Indebtedness) outstanding at the time of such acceleration will
first be entitled to receive payment in full of all amounts due thereon before
the Holders of Subordinated Debt Securities will be entitled to receive any
payment upon the principal of (or premium, if any) or interest, if any, on the
Subordinated Debt Securities. (Subordinated Indenture Section 1503)

No payments on account of principal (or premium, if any) or interest, if any, in
respect of the Subordinated Debt Securities may be made if there shall have
occurred and be continuing (i) a default in the payment of principal of (or
premium, if any) or interest on Senior Indebtedness, (ii) an event of default
with respect to any Senior Indebtedness resulting in the acceleration of the
maturity thereof, or (iii) any other event of default permitting the holders of
Senior Indebtedness to accelerate the maturity or demand payment in full.
(Subordinated Indenture Section 1504)

The Subordinated Indenture does not limit or prohibit the incurrence of
additional Senior Indebtedness, which may include Senior Subordinated
Indebtedness.

The applicable Prospectus Supplement may further describe the provisions, if
any, applicable to the subordination of the Subordinated Debt Securities of a
particular series.  If the Senior Debt Securities are issued on a senior
subordinated basis, the applicable Prospectus Supplement will describe the
related subordination provisions.  All Senior Debt Securities, whether issued on
a senior or senior subordinated basis, will be senior in right of payment to
each series of Subordinated Debt Securities.

CERTAIN COVENANTS OF THE COMPANY

RESTRICTIONS ON MERGER AND SALE OF ASSETS

Each Indenture provides that the Company may not consolidate with or merge into
any other Person or sell, lease or otherwise transfer its property and assets
as, or substantially as, an entirety to any Person, and the Company may not
permit any Person to merge into or consolidate with the Company unless (i)
either (A) the Company will be the resulting or surviving entity or (B) any
successor or purchaser is a corporation, partnership, limited liability company
or trust organized under the laws of the United States of America, any State or
the District of Columbia, and any such successor or purchaser expressly assumes
the Company's obligations on the Debt Securities under a supplemental indenture;
(ii) immediately after giving effect to the transaction no Event of Default, and
no event which after notice or lapse of time or both would become an Event of
Default, shall have occurred and be continuing; and (iii) certain other
conditions are met. (Section 801). Upon any consolidation or merger into any
other Person or any conveyance, transfer or lease of the Company's assets as, or
substantially as, an entirety to any Person, the successor Person shall succeed
to, and be substituted for, the Company under the Indenture, and the Company,
except in the case of a lease, shall be relieved of all obligations and
covenants under the Indenture and the Debt Securities to the extent it was the
predecessor Person. (Section 802)

                                       8
<PAGE>
 
CONVERSION RIGHTS

The terms and conditions, if any, upon which Debt Securities are convertible
into Common Stock, Preferred Stock or other securities of the Company will be
set forth in the applicable Prospectus Supplement relating thereto. Such terms
will include the conversion price (or manner of calculation thereof), the
conversion period, provisions as to whether conversion will be at the option of
the Holders or the Company, the events requiring an adjustment of the conversion
price and provisions affecting conversion in the event of redemption of such
Debt Securities.

EVENTS OF DEFAULT AND NOTICE THEREOF

Unless otherwise specified in the Prospectus Supplement relating to a particular
series of Debt Securities, the following events are defined in the Indentures as
"Events of Default" with respect to Debt Securities of any series: (a) failure
to pay principal (including any sinking fund payment) of (or premium, if any,
on) any Debt Security of that series when due; (b) failure to pay any interest
on any Debt Security of that series when due, continued for 30 days; (c) failure
to perform any other covenant or agreement of the Company under the Applicable
Indenture (other than a covenant the performance of which is dealt with
specifically elsewhere in the Applicable Indenture or which has been included in
the Applicable Indenture solely for the benefit of a series of Debt Securities
other than that series), continued for 60 days after written notice as provided
in the Applicable Indenture; (d) certain events of bankruptcy, insolvency or
reorganization; (e) in the event Subordinated Debt Securities are issued to the
Nuevo Trust or a trustee of such trust in connection with the issuance of Trust
Securities by the Nuevo Trust, the voluntary or involuntary dissolution,
winding-up or termination of the Nuevo Trust, except in connection with the
distribution of Subordinated Debt Securities to the holders of Trust Securities
in liquidation of the Nuevo Trust, the redemption of all of the Trust Securities
of the Nuevo Trust, or certain mergers, consolidations or amalgamations, each as
permitted by the Declaration of the Nuevo Trust; and (f) any other Event of
Default provided with respect to Debt Securities of that series. (Section 501)

Except as defined in the Prospectus Supplement relating thereto, no Event of
Default with respect to Debt Securities of a particular series shall necessarily
constitute an Event of Default with respect to Debt Securities of any other
series. (Section 501) The Holders of a majority in principal amount of
the Outstanding Debt Securities of any series shall have the right, subject to
such provisions for indemnification of the Trustee, to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
under the Applicable Indenture or exercising any trust or power conferred on the
Trustee with respect to Debt Securities of that series. (Section 512)

If an Event of Default (other than an Event of Default specified in clause (d)
of the second preceding paragraph) with respect to Debt Securities of any series
at the time Outstanding shall occur and be continuing, either the Trustee or the
Holders of at least 25% in principal amount of the Outstanding Debt Securities
of that series may, by a notice in writing to the Company (and to the Trustee if
given by the Holders), declare the principal amount (or, if the Debt Securities
of that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all Debt
Securities of that series to be due and payable immediately; provided, however,
that under certain circumstances the Holders of a majority in aggregate
principal amount of Outstanding Debt Securities of that series may rescind or
annul such declaration and its consequences. (Section 502). If an Event of
Default specified in clause (d) of the next preceding paragraph occurs, the
outstanding Debt Securities automatically will become immediately payable
without any declaration or other act on the part of the Trustee or any Holder.
(Section 502). For information as to waiver of defaults, see "Modification and
Waiver" herein.

Reference is made to the Prospectus Supplement relating to any series of Offered
Debt Securities which are Original Issue Discount Securities for the particular
provisions relating to the principal amount of such Original Issue Discount
Securities due on acceleration upon the occurrence of an Event of Default and
the continuation thereof.

No Holder of a Debt Security of any series will have any right to institute any
proceeding with respect to the Applicable Indenture or for any remedy
thereunder, unless such Holder shall have previously given to the applicable
Trustee written notice of a continuing Event of Default with respect to Debt
Securities of that series and unless also the Holders of at least 25% in
principal amount of the Outstanding Debt Securities of the same series shall
have made written request, and offered reasonable indemnity to the applicable
Trustee, to institute such proceeding as trustee, and the applicable Trustee
shall not have received from the Holders of a majority in aggregate principal
amount of the Outstanding Debt Securities of the same series a direction
inconsistent with such request and shall have failed to institute such
proceeding within 60 days. (Section 507). However, such limitations do not apply
to a suit instituted by a
                                       9
<PAGE>
 
Holder of any Debt Security for enforcement of payment of the principal of (or
premium, if any) or interest, if any, on such Debt Security on or after the
respective due dates expressed in such Debt Security. (Section 508)

Subject to the provisions of the Trust Indenture Act, the Trustee will be under
no obligation to exercise any of its rights or powers under the Applicable
Indenture at the request of any of the Holders of Debt Securities unless they
shall have offered to the applicable Trustee security or indemnity in form and
substance reasonably satisfactory to such Trustee against the costs, expenses
and liabilities which might be incurred by it in compliance with such request.
(Section 603)

The Company will be required to furnish to each Trustee annually a statement by
certain officers of the Company as to whether the Company is in default in the
performance and observance of any of the terms, provisions and conditions of the
Applicable Indenture. (Section 1004)

Notwithstanding anything in the Indentures to the contrary, the right of any
Holder of a Debt Security to receive payment of the principal of (or premium, if
any) and interest on such Debt Security, on and after the respective due dates
expressed in such Debt Security (as the same may be extended in accordance with
the terms of such Debt Security) or to institute suit for the enforcement of any
such payment shall not be impaired or affected without the consent of such
Holder, including, in the case of a Subordinated Debt Security issued to the
Nuevo Trust, the holders of the Trust Preferred Securities. In addition, in the
case of a Subordinated Debt Security issued to the Nuevo Trust, if an Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal (or premium, if any) then a
holder of Trust Preferred Securities may directly institute a proceeding against
the Company for payment.

MODIFICATION AND WAIVER

Each Indenture will provide that modifications and amendments of such Indenture
may be made by the Company and the applicable Trustee, with the consent of the
Holders of not less than a majority in principal amount of each series
of the Outstanding Debt Securities under such Indenture affected by the
modification or amendment; provided, however, that no such modification or
amendment may, without the consent of the Holder of each such Outstanding Debt
Security affected thereby: (a) change the Stated Maturity of the principal of
(or premium, if any) or any installment of principal or interest, if any, on any
such Debt Security; (b) reduce the principal amount of (or premium, if any) or
the interest rate, if any, on any such Debt Security or the principal amount due
upon acceleration of an Original Issue Discount Security; (c) adversely affect
any right of repayment at the option of the Holder of any such Debt Security;
(d) reduce the amount of, or postpone the date fixed for, the payment of any
sinking fund or analogous obligation; (e) change the place or currency of
payment of principal of (or premium, if any) or the interest, if any, on any
such Debt Security; (f) impair the right to institute suit for the enforcement
of any such payment on or with respect to any such Debt Security on or after the
Stated Maturity (or, in the case of redemption, on or after the Redemption
Date); (g) reduce the percentage of the aggregate principal amount of
Outstanding Debt Securities of any series, the consent of the Holders of which
is necessary to modify or amend the Applicable Indenture; or (h) modify the
foregoing requirements or reduce the percentage of Outstanding Debt Securities
necessary to waive compliance with certain provisions of the Applicable
Indenture or for waiver of certain defaults. (Section 902)

The Holders of at least a majority of the principal amount of the Outstanding
Debt Securities of any series may, on behalf of all Holders of that series,
waive compliance by the Company with certain restrictive provisions of the
Applicable Indenture and waive any past default under such Indenture, except a
default in the payment of principal, premium or interest or in the performance
of certain covenants. (Sections 1008 and 513)

If the Nuevo Trust or the Property Trustee of the Nuevo Trust holds a series of
Subordinated Debt Securities no such amendment, modification or waiver which
requires the approval of the Holders of a certain percentage in principal amount
of such series of Subordinated Debt Securities shall be effective without the
approval of the holders of the same percentage of aggregate liquidation
preference of Trust Preferred Securities.

Each Indenture provides that a supplemental indenture which changes or
eliminates any covenant or other provision of such Indenture which has expressly
been included solely for the benefit of one or more particular series of Debt
Securities, or which modifies the rights of the Holders of such series with
respect to such covenant or other provision, shall be deemed not to affect the
rights under such Indenture of the Holders of Debt Securities of any other
series. (Section 902)

                                       10
<PAGE>
 
Each Indenture provides that modifications and amendments of such Indenture may
be made by the Company and the applicable Trustee, without the consent of the
Holders of any series of Debt Securities issued thereunder: (1) to evidence the
succession of another Person to the Company in accordance with the covenant
described under "Restrictions on Merger and Sale of Assets" and assumption by
any such successor of the covenants of the Company in such Indenture and in the
Debt Securities issued thereunder; (2) to add to the covenants of the Company or
to add any additional Events of Default; (3) to permit or facilitate the
issuance of Debt Securities in bearer form or to provide for uncertificated Debt
Securities to be issued thereunder; (4) to change or eliminate any provision of
such Indenture, provided that any such change or elimination shall become
effective only when there are no Debt Securities outstanding of any series
created prior to the execution of such supplemental indenture which are entitled
to the benefit of such provision; (5) to secure any Debt Securities issued
thereunder; (6) to establish the form or terms of Debt Securities issued
thereunder; (7) to evidence and provide for a successor trustee under such
Indenture with respect to one or more series of Debt Securities issued
thereunder or to provide for or facilitate the administration of the trusts
under such Indenture by more than one trustee; or (8) to cure any ambiguity, to
correct or supplement any provision in such Indenture that may be inconsistent
with any other provision of such Indenture or to make any other provisions with
respect to matters or questions arising under such Indenture, provided that such
action shall not adversely affect the interests of the Holders of any series of
Debt Securities issued thereunder. (Section 901)

The Indentures provide that in determining whether the Holders of the requisite
principal amount of the Outstanding Debt Securities of any series have given or
taken any direction, notice, consent, waiver or other action under the Indenture
as of any date, (i) the principal amount of an Original Issue Discount Debt
Security that will be deemed to be Outstanding will be the amount of the
principal thereof that would be due and payable as of such date upon
acceleration of the Maturity thereof to such date; (ii) if, as of such date, the
principal amount payable at the Stated Maturity of a Debt Security is not
determinable (for example, because it is based on an index), the principal
amount of such Debt Security deemed to be Outstanding as of such date will be an
amount determined in the manner prescribed for such Debt Security; and (iii) the
principal amount of a Debt Security denominated in one or more foreign
currencies or currency units that will be deemed to be Outstanding will be the
United States dollar equivalent, determined as of such date in the manner
prescribed for such Debt Security, of the principal amount of such Debt Security
(or, in the case of a Debt Security described in clause (i) or (ii) above, of
the amount described in such clause). Certain Debt Securities, including those
for which payment or redemption money has been deposited or set aside in trust
for the Holders and those that have been fully defeased pursuant to the
Applicable Indenture, will not be deemed to be Outstanding. (Section 101) For
purposes of the Indentures, the Debt Securities of any series "Outstanding"
thereunder are deemed to exclude those held by Persons (other than the Nuevo
Trust if it has issued Trust Preferred Securities) that control, are controlled
by or are under common control with the Company; provided that any Person who
does not own, directly or indirectly, more than 5% of the outstanding voting
securities of the Company will not be deemed to control the Company. (Section
101)

Except in certain limited circumstances, the Company will be entitled to set any
day as a record date for the purpose of determining the Holders of Outstanding
Debt Securities of any series entitled to give or take any direction, notice,
consent, waiver or other action under the Indentures, in the manner and subject
to the limitations provided in the Applicable Indenture. In certain limited
circumstances, the Trustee will be entitled to set a record date for action by
Holders. If a record date is set for any action to be taken by Holders of a
particular series, such action may be taken only by persons who are Holders of
Outstanding Debt Securities of that series on the record date. To be effective,
such action must be taken by Holders of the requisite principal amount of such
Debt Securities within a specified period following the record date. For any
particular record date, this period will be 180 days or such shorter period as
may be specified by the Company (or the Trustee, if it set the record date), and
may be shortened or lengthened (but not beyond 180 days) from time to time.
(Section 104)

DEFEASANCE AND COVENANT DEFEASANCE

Each Indenture provides, if such provision is made applicable to the Debt
Securities of any series pursuant to Section 301 of the Indentures (which will
be indicated in the Prospectus Supplement applicable thereto), that the Company
may elect either (A) to defease and be discharged from any and all obligations
with respect to such Debt Securities then outstanding (except for the
obligations to exchange or register the transfer of such Debt Securities, to
replace temporary or mutilated, destroyed, lost or stolen Debt Securities, to
maintain an office or agency in respect of the Debt Securities, and to hold
monies for payments in trust) ("defeasance"), or (B) to be released from its
obligations with respect to such Debt Securities concerning the restrictions
described under "Restrictions on Merger and Sale of Assets" (Section 801) and
any other covenants applicable to such Debt Securities which are subject to
covenant defeasance ("covenant defeasance"), and the occurrence of an event
described and notice thereof in clause (c) under 

                                       11
<PAGE>
 
"Events of Default and Notice Thereof" (with respect to covenants determined,
pursuant to Section 301 of the Applicable Indenture, to be subject to covenant
defeasance) shall no longer be an Event of Default, in each case, upon the
irrevocable deposit with the applicable Trustee (or other qualifying trustee),
in trust for such purpose, of money, and/or U.S. Government Obligations (as
defined in the Indentures) which through the payment of principal and interest
in accordance with their terms will provide money in an amount sufficient
without reinvestment to pay the principal of (and premium, if any) and interest,
if any, on such Debt Securities, and any mandatory sinking fund or analogous
payments thereon, on the scheduled due dates therefor. Such a trust may only be
established if, among other things, (i) the Company has delivered to the
applicable Trustee an opinion of counsel (as specified in the Applicable
Indenture) to the effect that the Holders of such Debt Securities will not
recognize income, gain or loss for federal income tax purposes as a result of
such defeasance or covenant defeasance and will be subject to federal income tax
on the same amounts, in the same manner and at the same times as would have been
the case if such defeasance or covenant defeasance had not occurred, (ii) no
Event of Default or event which with the giving of notice or lapse of time, or
both, would become an Event of Default under the Indenture shall have occurred
and be continuing on the date of such deposit or, insofar as Events of Default
from bankruptcy, insolvency or reorganization events are concerned, at any time
in the period ending on the 91st day after such date of deposit and (iii)
certain other customary conditions precedent are satisfied. In the case of
defeasance under clause (A) above, the opinion of counsel referred to in clause
(i) above must refer to and be based on a ruling of the Internal Revenue Service
issued to the Company or published as a revenue ruling or on a change in
applicable federal income tax law, in each case after the date of such
Indenture. (Article Thirteen)

The Company may exercise the defeasance option with respect to such Debt
Securities notwithstanding its prior exercise of the covenant defeasance option.
If the Company exercises the defeasance option, payment of such Debt Securities
may not be accelerated because of an Event of Default. If the Company exercises
the covenant defeasance option, payment of such Debt Securities may not be
accelerated by reference to the covenants noted under clause (B) above. In the
event the Company omits to comply with the remaining obligations with respect to
such Debt Securities under such Indenture after exercising its covenant
defeasance option and such Debt Securities are declared due and payable because
of the occurrence of any Event of Default, the amount of money and U.S.
Government Obligations on deposit with the applicable Trustee may be
insufficient to pay amounts due on the Debt Securities of such series at the
time of the acceleration resulting from such Event of Default, because the
required deposit in the defeasance trust is based upon scheduled cash flows,
rather than market values, which will vary depending on prevailing interest
rates and other factors. However, the Company will remain liable in respect of
such payments. (Article Thirteen)

The Prospectus Supplement may further describe the provisions, if any,
applicable to defeasance or covenant defeasance with respect to the Debt
Securities of a particular series.

CERTAIN DEFINITIONS

Set forth below is a summary of certain of the defined terms used in the
Indentures. Reference is made to the Applicable Indenture with respect to any
particular series of Debt Securities for the full definition of all such terms,
as well as any other terms used herein for which no definition is provided.

"Capital Stock" means, with respect to any Person, any and all shares,
interests, participations, rights in or other equivalents in the equity
interests (however, designated) in such Person, any rights (other than debt
securities convertible into an equity interest),  warrants or options
exercisable for, exchangeable for or convertible into such an equity interest in
such Person.

"Capitalized Lease Obligation" means any obligation to pay rent or other amounts
under a lease of (or other agreement conveying the right to use) any property
(whether real, person or mixed) that is required to be classified and accounted
for as a capital lease obligation under GAAP.

"GAAP" means generally accepted accounting principles, consistently applied,
that are set forth in the opinions and pronouncements of the Accounting
Principles Board of the American institute of Certified Public Accountants and
statements and pronouncements of the Financial Accounting Standards Board or in

segment of the accounting profession of the United States of America, which are
effective on the date of this Indenture.

"Indebtedness" means, with respect to any Person, without duplication, (a) all
liabilities of such Person for borrowed money or for the deferred purchase price
of property or services (excluding any trade accounts payable and other accrued
current liabilities incurred in the ordinary course of  business), and all
liabilities of such Person incurred in connection with any letters of credit,
bankers' acceptances or other similar 

                                       12

otherwise acquire for value any Capital Stock of such Person, or any warrants,
rights or options to acquire such Capital Stock outstanding on the date of the
Subordinated Indenture or thereafter, (b) all obligations of such Person
evidenced by bonds, notes, debentures or other similar instruments, (c) all
Indebtedness of such Person created or arising under any conditional sale or

though such Person has not assumed or become liable for the payment of such
Indebtedness (the amount of such obligation being deemed to be the lesser of the
value of such property or asset or the amount of the obligation so secured), (f)
all guarantees by such Person of Indebtedness referred to in this definition
(including, with respect to any Production Payments and Reserve Sales, any
warranties or guaranties of production or payment by such Person with respect to

Capital Stock as if such Redeemable Capital Stock were purchased on any date on
which Indebtedness shall be required to be determined pursuant to the
Subordinated Indenture, and if such price is based upon, or measured by, the
fair market value of such Redeemable Capital Stock, such fair market value shall
be determined in good faith by the board of directors of the issuer of such
Redeemable Capital Stock; provided, however, that if such Redeemable Capital
Stock is not at the date of determination permitted or required to be
repurchased, the "maximum fixed repurchase price" shall be the book value of
such Redeemable Capital Stock. Subject to clause (f) of the first sentence of
this definition, Production Payments and Reserve Sales shall not be deemed
Indebtedness.

calculated by applying a fixed or a floating rate of interest on the same
notional amount and shall include, without limitation, interest rate swaps,
caps, floors, collars and similar agreements or arrangements designed to protect
against or manage such Person's and any of its Subsidiaries' exposure to
fluctuations in interest rates.

"Person" means any individual, corporation, limited liability company,
partnership, joint venture, association, joint stock company, trust,
unincorporated organization or government or any agency or political subdivision

obligation of the grantor or transferor to operate and maintain, or cause the
subject interest to be operated and maintained, in a reasonably prudent manner
or other customary standard or subject to the obligation of the grantor or
transferor to indemnify for environmental matters.

"Redeemable Capital Stock" means any Capital Stock that, either by its terms, by
the terms of any security into which it is convertible or exchangeable or by
contract or otherwise, is, or upon the happening of an event or passage of time
would be, required to be redeemed prior to the final date specified in the
Subordinated Debt Securities as the fixed date on which the principal of such
Subordinated Debt Securities is due and payable ("Stated Maturity") or is

Stated Maturity, or is convertible into or exchangeable for debt securities at
any time prior to such final Stated Maturity.

"Senior Indebtedness" means the principal of (and premium, if any) and interest,
if any (including interest accruing on or after the filing of any petition in

                                       13
<PAGE>
 
of the Company, whether incurred on or prior to the date of the Applicable
Indenture or thereafter incurred, unless, in the instrument creating or
evidencing the same or pursuant to which the same is outstanding, it is provided
that such obligations are not superior in right of payment to the Offered Debt
Securities, or to other Indebtedness of the Company which is pari passu with, or
subordinated to the Offered Debt Securities; provided, however, that Senior
Indebtedness shall not be deemed to include the Offered Debt Securities or any
Indebtedness of the Company to any Subsidiary of the Company. (Subordinated
Indenture Section 101)

"Subsidiary" of any Person means (i) a corporation more than 50% of the combined
voting power of the outstanding voting stock of which is owned, directly or
indirectly, by such Person or by one or more other Subsidiaries of such Person

PERMANENT GLOBAL SECURITIES

The Debt Securities of a series may be issued in the form of one or more
permanent Global Securities that will be deposited with a Depositary or its
nominee. In such a case, one or more Global Securities will be issued in a
denomination or aggregate denominations equal to the portion of the aggregate
principal amount of Outstanding Debt Securities of the series to be represented
by such Global Security or Securities. The Prospectus Supplement relating to
such series of Debt Securities will describe the circumstances, if any, under
which beneficial owners of interests in any such permanent Global Security may
exchange such interests for Debt Securities of such series and of like tenor and
principal amount in any authorized form and denomination. Unless and until it is
exchanged in whole or in part for Debt Securities in definitive registered form,
a permanent Global Security may not be registered for transfer or exchange
except in the circumstances described in the applicable Prospectus Supplement.
(Sections 204 and 305)

The specific terms of the depositary arrangement with respect to any portion of
a series of Debt Securities to be represented by a permanent Global Security and
a description of the Depositary will be contained in the applicable Prospectus
Supplement.

GOVERNING LAW

The Indentures and the Debt Securities will be governed by and construed in
accordance with the internal laws of the State of New York. (Section 112)

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

The following description of the capital stock of the Company is subject to the
detailed provisions of the Company's Certificate of Incorporation, as amended

of the provisions of statutory or common law and is subject to, and qualified in
its entirety by reference to, the Certificate of Incorporation and the Bylaws,
each of which are filed as an exhibit to the Registration Statement of which
this Prospectus is a part.

The Company has 50,000,000 authorized shares of Common Stock, par value $.01 per
share. Holders of Common Stock are entitled to receive dividends if, when and as
declared by the Board of Directors of the Company out of funds legally available
therefor. All shares of Common Stock have equal voting rights on the basis of
one vote per share on all matters to be voted upon by stockholders. Cumulative
voting for the election of directors is not permitted. Shares of Common Stock
have no preemptive, conversion, sinking fund or redemption provisions and are
not liable for further call or assessment. Each share of Common Stock is
entitled to share on a pro rata basis in any assets available for distribution
to the holders of the Common Stock upon liquidation of the Company after
satisfaction of any liquidation preference on any series of the Company's
preferred stock. All outstanding shares of Common Stock have been, and all
shares offered in any offering of Offered Securities will be when issued,
validly issued, fully paid and nonassessable.  As of November 8, 1996, there
were 18,976,085 shares of Common Stock issued and outstanding. As of November 8,
1996, a total of 4,863,493 shares of Common Stock were reserved for issuance
of which (a) 863,493 shares were reserved for conversion of the 7% Preferred
Stock (as defined 

                                       14
<PAGE>
 
below), (b) 1,500,000 shares were reserved for exercise of stock options under
the 1990 Stock Option Plan ("1990 Plan") and (c) 2,500,000 shares were reserved
for issuance of options under the Company's 1993 Stock Incentive Plan ("1993
Plan"). As of the date hereof, options to purchase 556,150 and 964,788
shares of Common Stock were outstanding under the 1990 Plan and the 1993 Plan,
respectively. On April 9, 1996, the Company issued warrants to purchase 150,000
shares of Common Stock. These warrants are initially exercisable at $28 per
share and have a maximum term of five years.

PREFERRED STOCK

The following description of the terms of the Preferred Stock sets forth certain
general terms and provisions of the Preferred Stock to which a Prospectus
Supplement may relate. Specific terms of any series of Preferred Stock offered
by a Prospectus Supplement will be described in the Prospectus Supplement
relating to such series. The description set forth below is subject to and
qualified in its entirety by reference to the certificate of designations
establishing a particular series of Preferred Stock, which will be filed with
the Commission in connection with the offering of such series.

Under the Certificate, the Board of Directors of the Company is authorized,
without further stockholder action, to provide for the issuance of up to
10,000,000 shares of Preferred Stock in one or more series. As of the date of
this Prospectus, the 7% Preferred Stock is the only series of Preferred Stock
issued and outstanding. The rights, preferences, privileges, and restrictions,
including dividend rights, voting rights, conversion rights, terms of
redemption, and liquidation preferences, of the Preferred Stock of each series
will be fixed or designated by the Board of Directors pursuant to a certificate
of designations. The specific terms of a particular series of Preferred Stock
offered hereby will be described in a Prospectus Supplement relating to such
series and will include the following: (a) the maximum number of shares to
constitute the series and the distinctive designation thereof; (b) the annual
dividend rate, if any, on shares of the series (or the method of calculating
such rate), whether such rate is fixed or variable or both, the date or dates
from which dividends will begin to accrue or accumulate, and whether dividends
will be cumulative; (c) whether the shares of the series will be redeemable and,
if so, the price at and the terms and conditions on which such shares may be
redeemed, including the time during which such shares may be redeemed and any
accumulated dividends thereon that the holders of such shares shall be entitled
to receive upon the redemption thereof; (d) the liquidation preference, if any,
applicable to shares of the series; (e) whether the shares of the series will be
subject to operation of a retirement or sinking fund and, if so, the extent and
manner in which any such fund shall be applied to the purchase or redemption of
such shares for retirement or for other corporate purposes, and the terms and
provisions relating to the operation of such fund; (f) the terms and conditions,
if any, on which the shares of the series will be convertible into, or
exchangeable for, shares of any other class or classes of capital stock of the
Company, the Nuevo Trust or another issuer or any series of any other class or
classes, or of any other series of the same class, including the price or rate
of conversion or exchange and the method, if any, of adjusting the same; (g) the
voting rights, if any, on the shares of the series; and (h) any other
preferences and relative, participating, optional, or other special rights or
qualifications, limitations, or restrictions thereof.

Each series of Preferred Stock will, when issued, be fully paid and non-
assessable.

The transfer agent, registrar, and dividend disbursement agent for a series of
Preferred Stock will be selected by the Company and will be described in the
applicable Prospectus Supplement.

7% CUMULATIVE CONVERTIBLE PREFERRED STOCK

On May 28, 1992, the Company sold $25,000,000 of 7% Cumulative Convertible
Preferred Stock, $1.00 par value per share, Series A and B (collectively, the
"7% Preferred Stock") to The 1818 Fund, L.P. ("1818 Fund").  The Company issued
22,500 shares and 2,500 shares of 7% Preferred Stock, Series A and Series B,
respectively.  As of November 8, 1996, there were 11,220 shares of 7%
Preferred Stock issued and outstanding. The 7% Preferred Stock, Series B, has
the same powers, preferences, rights, qualifications and restrictions as the 7%
Preferred Stock, Series A.  The holders of the 7% Preferred Stock are entitled
to receive dividends payable in arrears as of the last day of March, June,
September and December.  The 7% Preferred Stock is convertible into shares of
Common Stock equal to the liquidation preference of $1,000 per share divided by
a current conversion price of approximately $13 per share, subject to
adjustment.  9,881 Series A shares were converted into Common Stock on September
21, 1995.  Upon a change of control (as defined in the Designation establishing
the shares), dividends on the 7% Preferred Stock will be payable at a rate of
14% per annum.  The holders of the 7% Preferred Stock are entitled to vote with
the Common Stock on all matters except that the holders of the 7% Preferred
Stock have separate class voting rights on certain matters that affect the
rights of such holders, and are entitled to certain registration rights.  The
Company may redeem the 7% Preferred Stock on or after June 30, 1997, at a price
per share equal to the liquidation preference plus a 4% premium that decreases
ratably to zero after five years.  Upon a change of control, the Company has the
option to redeem the 7% Preferred Stock at a price per share equal to 125% of
the liquidation preference plus accrued and unpaid dividends, if such redemption
occurs prior to June 30, 1997.  The holders of the 7% Preferred Stock have the
right to convert the shares of 7% Preferred Stock into Common Stock on or after
May 28, 1999 through May 28, 2002, at an adjusted price based on the market
price of the Common Stock subject to certain limitations, including a minimum
price of $10.00 per share.  The holders of the 7% Preferred Stock have the right
to appoint a representative to the Company's Board of Directors in the event the
Company fails to pay dividends for two quarters (whether consecutive or not) or
breaches certain provisions of the stock purchase agreement.

In connection with the acquisition of the 7% Preferred Stock, the Company and
the 1818 Fund entered into a registration rights agreement pursuant to which the
Company agreed to register, on three occasions upon demand by the 1818 Fund, the
Preferred Stock or the Common Stock into which such Preferred Stock is
convertible.  The agreement also grants the 1818 Fund "piggy back" registration
rights to include Preferred Stock or shares of Common Stock received upon
conversion thereof in certain registration statements filed by the Company, and
the 1818 Fund has exercised such rights with respect to all of its shares of
Common Stock covered by this Prospectus.  See "Selling Stockholders."

                        CERTAIN ANTI-TAKEOVER PROVISIONS

GENERAL

The Certificate contains several provisions that may make the acquisition of
control of the Company by means of a tender offer, open market purchases, a
proxy fight or otherwise more difficult. The Bylaws also contain provisions that
could have an anti-takeover effect. Many of the following provisions contain
requirements for a vote of 80% or more of the Company's stockholders.

BOARD OF DIRECTORS

Classified Board of Directors. The Certificate and Bylaws provide for the
Company's board of directors (the "Board of Directors") to be divided into three
classes of directors serving staggered three-year terms. As a result,
approximately one-third of the Board of Directors is elected each year.  The
classification of directors will have the effect of making it more difficult for
stockholders of the Company to change the composition of the Board of Directors
in a relatively short period of time. At least two annual meetings of
stockholders, instead of one, will generally be required to effect a change in a
majority of the directors of the Board of Directors.  The classified Board of
Directors provision could have the effect of discouraging a third party from
making a tender offer or otherwise attempting to obtain control of the Company,
even though such an attempt might be beneficial to the Company and its
stockholders. The classified Board of Directors provision could thus increase
the likelihood that incumbent directors will retain their positions.

Number of Directors. The Bylaws provide that the number of directors shall be
not less than three nor more than twenty-one directors, the exact number to be
fixed from time to time by either (i) the Board of Directors, (ii) the
affirmative vote of 80% or more of the voting power of the shares of the Company
or (iii) the Certificate. Accordingly, the Board of Directors could prevent any
stockholder from obtaining 

                                       16
<PAGE>
 
majority representation on the Company's Board of Directors by enlarging the
size of the Board of Directors and filling the new directorships with the Board
of Directors' own nominees.

Removal of Directors. The Certificate provides that, subject to the rights of
the holders of any series of any preferred stock then outstanding, any director
or the entire Board of Directors may be removed from office at any annual or
special meeting called for such purpose, and then only for cause and only by the
affirmative vote of the holders of 80% or more of the voting power of all the
shares of the Company entitled to vote generally in the election of directors,
voting together as a single class. For purposes of director removal, cause means
only the following:  conviction of a felony, proof beyond the existence of a
reasonable doubt that a director has committed grossly negligent or willful
misconduct resulting in material detriment to the Company or commission of a
material breach of fiduciary duty to the Company resulting in a material
detriment to the Company.

The removal of directors provisions could have the effect of discouraging a
third party from attempting to obtain control of the Company, even though such
an attempt might be beneficial to the Company and its stockholders. This
provision could also affect the ability of the stockholders of the Company to
remove incumbent directors and thus may increase the likelihood that incumbent
directors will retain their positions.

Newly-Created Directorships and Vacancies. Subject to the rights of the holders
of any series of any preferred stock then outstanding, newly-created
directorships resulting from any increase in the authorized number of directors
and any vacancies in the Board of Directors resulting from death, resignation,
retirement, disqualification, removal from office or other cause may be filled
by a majority vote of the directors then in office even though less than a
quorum, or by a sole remaining director.  The newly-created directorship and
vacancy provisions could prevent a stockholder from obtaining a position on the
Board of Directors. These provisions could also have the effect of making it
more difficult for stockholders to change the composition of the Board of
Directors of the Company.

SPECIAL MEETINGS

The Bylaws provide that special meetings of stockholders may be called only by
the President, or by the Board of Directors or by the written order of a
majority of the directors, and shall be called by the President or Secretary at
the request in writing of stockholders owning 80% or more of the entire capital
stock of the Company issued and outstanding and entitled to vote. Accordingly,
holders of a significant percentage of the outstanding capital stock of the
Company may not be able to request a special meeting of the stockholders.

COMMON AND PREFERRED STOCK

The Certificate authorizes the Board of Directors to determine, with respect to
any series of Preferred Stock of the Company, the terms and rights of
such series, including the following: (i) the designation of such series and the
number of shares which shall constitute such series, (ii) the rate and time of,
and conditions with respect to, dividends, and whether such dividends are
cumulative, (iii) the price, timing and conditions regarding the redemption of
shares of such series, (iv) the rights and preferences of shares of such series
in the event of dissolution, liquidation or winding up of the affairs of the
Company, (v) the sinking fund provisions, if any, for the redemption or purchase
of shares of such series, (vi) the voting rights, if any, of shares of such
series, (vii) the right, if any, to convert or exchange shares of such series
into or for stock or securities of any other series or class, (viii) the status
as to, re-issuance or sale of such shares redeemed, purchased or otherwise
reacquired, or surrendered to the Company on conversion, (ix) the conditions and
restrictions, if any, on the payment of dividends or on the making of other
distributions on, or the purchase, redemption or other acquisition by the
Company or any subsidiary, of Common Stock or of any other class of stock of the
Company ranking prior to such shares as to dividends or upon liquidation, (x)
the conditions, if any, on the creation of indebtedness of the Company or any
subsidiary and (xi) any other preferences or other special or relative rights of
shares of such series. The Certificate provides that the Common Stock of the
Company shall be junior to the Preferred Stock and is subject to all the rights,
privileges, preferences and priorities of the preferred stock as set forth in
the Certificate or as determined by the Board of Directors, including the
issuance of dividends and distribution of assets in the event of liquidation,
dissolution or winding up. The exclusive voting power of the Company shall be
vested in the Common Stock of the Company, subject to any particular class or
series of Preferred Stock with additional voting rights. No holder of any stock
of any class of the Company shall, as such holder, have any right to purchase or
subscribe for any shares of the capital stock of any class of securities which
the Company may issue or sell, nor shall any holder of any such stock have any
right to purchase or subscribe for any obligation which the Company may issue or
sell that shall be convertible into, or exchangeable for, any shares of the
capital stock of the Company, or to 

                                       17
<PAGE>
 
which shall be attached any warrant or instrument that shall confer upon the
owner of such obligation, warrant or instrument the right to subscribe for, or
to purchase from the company any shares of its capital stock of any class.

The preemptive rights and the Preferred Stock provisions could have the effect
of diluting the voting rights of the Common Stockholders of the Company by
placing voting power in the hands of Preferred Stockholders to the exclusion of
the Common Stockholders.

The Company believes that the availability of Preferred Stock provides it with
increased flexibility in structuring possible future financing and acquisitions,
and in meeting other corporate needs which might arise. Having such authorized
shares available for issuance will allow the Company to issue shares of
Preferred Stock without the expense and delay of a special stockholders'
meeting. The authorized shares of Preferred Stock as well as shares of the
Company's Common Stock, will be available for issuances without further action
by the stockholders, unless such action is required by applicable law or the
rules of any stock exchange on which the Company's capital stock may then be
listed. Although the Board of Directors has no intention at the present time of
doing so, it could issue a series of Preferred Stock that could, depending on
the terms of such series, either impede or facilitate the completion of a
merger, tender offer or other takeover attempt. For instance, such series of
Preferred Stock might impede a business combination by including class voting
rights which would enable the holder to block such a transaction or facilitate a
business combination by including voting rights which would provide a required
percentage vote of stockholders. The Board of Directors will make any
determination to issue such shares based on its judgment as to the respective
best interests of the Company and its then existing stockholders.

BUSINESS COMBINATIONS

The Certificate requires that the following procedures be observed in connection
with the authorization of transactions involving an interested stockholder which
could eliminate or fundamentally change the interests of the remaining
stockholders of the Company ("Business Combinations").

If a Business Combination is proposed which will directly or indirectly involve
an "Interested Stockholder" (as hereinafter defined), such Business Combination
must be approved by the affirmative vote of the holders of the Company's capital
stock representing at least 80% of the votes entitled to be cast by the holders
of all the then outstanding shares of the voting stock, voting together as a
single class, and by the affirmative vote of at least a majority of the entire
Board of Directors of the Company unless such Business Combination is approved
by the majority of the directors who were in office prior to the time the
Interested Stockholder became an Interested Stockholder and who continue in
office (the "Continuing Directors").

A Business Combination includes:

(i) any merger or consolidation of the Company or any subsidiary thereof with
(a) any Interested Stockholder or (b) any other company (whether or not itself
an Interested stockholder) which is, or after such merger or consolidation would
be, an Affiliate or Associate (as hereinafter defined) of an Interested
Stockholder; or

(ii) any sale, lease, exchange, mortgage, pledge, transfer, or other disposition
or security arrangement, investment, loan, advance, guarantee, agreement to
purchase, agreement to pay, extension of credit, joint venture participation, or
other agreement (in one transaction or a series of transactions) with or for the
benefit of any Interested Stockholder or any Affiliate or Associate of an
Interested Stockholder involving any assets, securities, or commitments of the
Company, any subsidiary of any Interested Stockholder, or any Affiliate or
Associate of any Interested Stockholder having an aggregate fair market value
and/or involving aggregate commitments of $1,000,000 or more; or

(iii) the adoption of any plan or proposal for the liquidation or dissolution of
the Company which is voted for, approved, or consented to by any Interested
Stockholder; or

(iv) any reclassification of securities (including any reverse stock split), or
recapitalization of the Company, or any merger or consolidation of the Company
with any of its subsidiaries, or any other transaction (whether or not with or
otherwise involving an Interested Stockholder) that has the effect, directly or
indirectly, of increasing the proportionate share of any class or series of
capital stock, or any securities convertible into capital stock or into equity
securities of any subsidiary, that is beneficially owned by any Interested
Stockholder or any Affiliate or Associate of any Interested Stockholder; or

                                       18
<PAGE>
 
(v) any agreement, contract, or other arrangement providing for any one or more
of the actions specified in the foregoing clauses (i) to (iv).

An "Interested Stockholder" is any person (other than the Company or any
subsidiary thereof and other than any profit-sharing, employee stock ownership,
or other employee benefit plan of the Company or any subsidiary or any trustee
of or fiduciary with respect to any such plan when acting in such capacity) who
(i) is the beneficial owner of voting stock representing 20% or more of the
votes entitled to be cast by the holders of all then outstanding shares of
voting stock or (ii) is an Affiliate or Associate of the Company and at any time
within the two-year period immediately prior to the date in question was the
beneficial owner of voting stock representing 20% or more of the votes entitled
to be cast by the holders of all then outstanding shares of voting stock.

"Affiliate" and "Associate" shall have the respective meanings ascribed to such
terms in Rule 12b-2 under the Exchange Act as in effect on the date that the
Business Combination is approved by the Board of Directors (the term
"registrant" in such Rule 12b-2 meaning, in this case, the Company).

A majority of the Continuing Directors of the Company shall each have the power
and duty to determine, for the purposes of applying the Business Combination
provisions to their respective corporations, on the basis of information known
to them after reasonable inquiry (i) whether a person is an Interested
Stockholder, (ii) the number of shares of capital stock or other securities
beneficially owned by any person, (iii) whether a person is an Affiliate or
Associate of another, and (iv) whether the assets that are the subject of any
Business Combination have, or the consideration to be received for the issuance
or transfer of securities by the Company or any subsidiary in any Business
Combination has, an aggregate fair market value of $1,000,000 or more.

AMENDMENT OF CERTAIN PROVISIONS OF THE CERTIFICATE AND BYLAWS

The Certificate contains provisions requiring the affirmative vote of the
holders of at least 80% of the voting stock to amend the provisions relating to
the election and number of directors and Business Combinations described above.
The Bylaws contain provisions requiring the affirmative vote of holders of at
least 80% of the voting stock to amend the provisions relating to special
meetings of stockholders. These provisions will make it more difficult for
stockholders to make changes in the Certificate or Bylaws, including changes
designed to facilitate the exercise of control over the Company.  In addition,
such requirements will enable the holders of a minority of stock to prevent the
holders of a majority or more of such stock from amending certain provisions of
the Certificate and Bylaws.  The requirements for such vote may be difficult to
obtain, since at least 80% of the Common Stock must be present or represented by
proxy at any meeting at which any such amendment is proposed and must vote in
favor of such amendment.

                            DESCRIPTION OF WARRANTS

The Company may issue warrants to purchase Debt Securities (the "Debt Warrants")
or Preferred Stock (the "Preferred Share Warrants", collectively with the Debt

any other Securities and may be attached to or separate from such Securities.
The Warrants are to be issued under warrant agreements (each a "Warrant
Agreement") to be entered into between the Company and a bank or trust company,

(11) any other terms of such Debt Warrants and terms, procedures and limitations
relating to the exercise of such Debt Warrants.

Debt Warrant certificates will be exchangeable for new Debt Warrant certificates
of different denominations, and Debt Warrants may be exercised at the corporate
trust office of the Warrant Agent or any other office indicated in the
Prospectus Supplement. Prior to the exercise of their Debt Warrants, holders of
Debt Warrants will not have any of the rights of holders of the securities

maximum or minimum number of such Warrants which may be exercised at any time.

EXERCISE OF WARRANTS

Each Warrant will entitle the holder of the Warrants to purchase for cash such
principal amount of Debt Securities or Preferred Stock at such exercise price as
shall in each case be set forth in, or be determinable as set forth in, the
Prospectus Supplement relating to the Warrants offered thereby. Warrants may be
exercised at any time up to the close of business on the expiration date set
forth in the Prospectus Supplement relating to the Warrants offered thereby.
After the close of business on the expiration date, unexercised Warrants will

                   DESCRIPTION OF TRUST PREFERRED SECURITIES

The Nuevo Trust may issue only one series of Trust Preferred Securities having
terms described in the Prospectus Supplement relating thereto. The Declaration
of the Nuevo Trust authorizes the Regular Trustees to issue on behalf of the
Nuevo Trust one series of Trust Preferred Securities. The Declaration will be
qualified as an indenture under the Trust Indenture Act. The Trust Preferred
Securities will have such terms, including distributions, redemption, voting,
liquidation, conversion rights and such other preferred, deferred or other
special rights or such restrictions as shall be set forth in the Declaration or
made part of the Declaration by the Trust Indenture Act, and which will mirror
the terms of the Subordinated Debt Securities held by the Property Trustee and
described in the Prospectus Supplement related thereto. Reference is made to the
Prospectus Supplement relating to the Trust Preferred Securities for specific
terms, including (i) the distinctive designation of such Trust Preferred
Securities; (ii) the number of Trust Preferred Securities; (iii) the annual
distribution rate (or method of determining such rate) for the Trust Preferred
Securities and the date or dates upon which such distributions shall be payable;
provided, however, that distributions on such Trust Preferred Securities shall
be payable on a quarterly basis to holders of such Trust Preferred Securities as
of a record date in each quarter during which such Trust Preferred Securities
are outstanding; (iv) whether distributions on the Trust Preferred Securities
shall be cumulative, and, in the case of Trust Preferred Securities having such
cumulative distribution rights, the date or dates or method of determining the
date or dates from which distributions on the Trust Preferred Securities shall
be cumulative; (v) the amount or amounts which shall be paid out of the assets
of the Nuevo Trust to the holders of the Trust Preferred Securities upon
voluntary or involuntary dissolution, winding-up or termination of the Nuevo
Trust; (vi) the obligation, if any, of the Nuevo Trust to purchase or redeem the
Trust Preferred Securities and the price or prices at which, the period or
periods within which, and the terms and conditions upon which, the Trust
Preferred Securities shall be purchased or redeemed, in whole or in part,
pursuant to such obligation; (vii) the voting rights, if any, of the Trust
Preferred Securities in addition to those required by law, including the number
of votes per Trust Preferred Security and any requirement for the approval by
the holders of the Trust Preferred Securities, as a condition to specified
action or amendments to the Declaration of the Nuevo Trust; (viii) the terms and
conditions, if any, upon which the Trust Preferred Securities may be converted
into shares of Common Stock, including the conversion price per share and the
circumstances, if any, under which any such conversion right shall expire; (ix)
the terms and conditions, if any, upon which the Subordinated Debt Securities
may be distributed to holders of the Trust Preferred Securities; (x) if
applicable, any securities exchange upon which the Trust Preferred Securities
shall be listed; and (xi) any other relevant rights, preferences, privileges,
limitations or restrictions of  the Trust Preferred Securities not inconsistent
with the Declaration of the Nuevo Trust or with applicable law.  All Trust
Preferred Securities offered hereby will be guaranteed by the Company to the
extent set forth below under "Description Of Trust Preferred Securities
Guarantee." Certain United States federal income tax considerations applicable
to any offering of Trust Preferred Securities will be described in the
Prospectus Supplement relating thereto.

In connection with the issuance of Trust Preferred Securities, the Nuevo Trust
will issue one series of Trust Common Securities. The Declaration of the Nuevo
Trust authorizes the Regular Trustees to issue on behalf of the Nuevo Trust one
series of Trust Common Securities having such terms including distributions,
redemption, voting and liquidation rights or such restrictions as shall be set
forth therein. The terms of the Trust Common Securities will be substantially
identical to the terms of the Trust Preferred Securities, and the Trust Common
Securities will rank pari passu, and payments will be made thereon pro rata,
with the Trust Preferred Securities except that, upon an event of default under
the Declaration, the rights of the holders of the Trust Common Securities to
payment in respect of distributions and payments upon liquidation, redemption
and otherwise will be subordinated to the rights of the holders of the Trust
Preferred Securities.  Except in certain limited circumstances, the Trust Common
Securities will also carry the right to vote to appoint, remove or replace any
of the Nuevo Trustees.  All of the Trust Common Securities will be directly or
indirectly owned by the Company.

PROPOSED TAX LEGISLATION

On March 19, 1996, as a part of President Clinton's Fiscal 1997 Budget Proposal,
the Treasury Department proposed legislation (the "Proposed Legislation") that,
among other things, would (i) treat as equity for United States federal income
tax purposes certain debt instruments with a maximum term of more than 20 years
and (ii) disallow interest deductions on certain convertible debt instruments or
defer interest deductions on certain debt instruments issued with original issue
discounts. The Proposed Legislation is proposed to be effective for debt
instruments issued on or after December 7, 1995.

On March 29, 1996, Senate Finance Committee Chairman William V. Roth, Jr. and
House Ways and Means Committee Chairman Bill Archer issued a joint statement
(the "Joint Statement") indicating their intent that the Proposed Legislation,
if adopted by either of the tax-writing committees of Congress, would 

                                       21
<PAGE>
 
have an effective date that is no earlier than the date of "appropriate
Congressional action." However, there can be no assurances that the effective
date guidance contained in the Joint Statement will be incorporated in the
Proposed Legislation, if enacted, or that other legislation enacted after the
date hereof will not otherwise adversely affect the tax treatment of the
Subordinated Debt Securities. In addition, there can be no assurances as to
whether or in what form the Proposed Legislation may be enacted into law or
whether other legislation will be enacted that otherwise adversely affects the
tax treatment of the Subordinated Debt Securities and the Trust Preferred
Securities.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES

If an Event of Default under the Declaration of the Nuevo Trust occurs and is
continuing, then the holders of the Trust Preferred Securities would rely on the
enforcement by the Property Trustee of its rights as a holder of the
Subordinated Debt Securities against the Company. In addition, the holders of a
majority in liquidation amount of the Trust Preferred Securities will have the
right to direct the time, method, and place of conducting any proceeding for any
remedy available to the Property Trustee or to direct the exercise of any trust
or power conferred upon the Property Trustee under the Declaration, including
the right to direct the Property Trustee to exercise the remedies available to
it as a holder of the Subordinated Debt Securities.  If the Property Trustee
fails to enforce its rights under such of Subordinated Debt Securities, a holder
of the Trust Preferred Securities may institute a legal proceeding directly
against the Company to enforce the Property Trustee's rights under such
Subordinated Debt Securities without first instituting any legal proceeding
against the Property Trustee or any other person or entity. Notwithstanding the
foregoing, if an Event of Default under the applicable Declaration has occurred
and is continuing and such event is attributable to the failure of the Company
to pay interest or principal on such Subordinated Debt Securities on the date
such interest or principal is otherwise payable (or in the case of redemption,
on the redemption date), then a holder of the Trust Preferred Securities may
directly institute a proceeding for enforcement of payment to such holder of the
principal of or interest on such Subordinated Debt Securities having a principal
amount equal to the aggregate liquidation amount of the Trust Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Subordinated Debt Securities. In connection with such
Direct Action, the Company will be subrogated to the rights of such holder of
the Trust Preferred Securities under the Declaration to the extent of any
payment made by the Company to such holder of Trust Preferred Securities in such
Direct Action.

              DESCRIPTION OF TRUST PREFERRED SECURITIES GUARANTEE

Set forth below is a summary of information concerning the Trust Preferred
Securities Guarantee which will be executed and delivered by the Company for the
benefit of the holders from time to time of Trust Preferred Securities.  The
Trust Preferred Securities Guarantee will be qualified as an indenture under the
Trust Indenture Act. Wilmington Trust Company will act as the independent
trustee under the Trust Preferred Securities Guarantee (the "Preferred Guarantee
Trustee") for purposes of the Trust Indenture Act. The terms of the Trust
Preferred Securities Guarantee will be those set forth in the Trust Preferred
Securities Guarantee and those made part of the Trust Preferred Securities
Guarantee by the Trust Indenture Act. The summary is subject in all respects to
the provisions of, and is qualified in its entirety by reference to, the form of
Trust Preferred Securities Guarantee, which is filed as an exhibit to the
Registration Statement of which this Prospectus forms a part, and the Trust
Indenture Act. Each Trust Preferred Securities Guarantee will be held by the
Preferred Guarantee Trustee for the benefit of the holders of the Trust
Preferred Securities.

GENERAL

Pursuant to the Trust Preferred Securities Guarantee, the Company will agree, to
the extent set forth therein, to pay in full, to the holders of the Trust
Preferred Securities, the Guarantee Payments (as defined herein) (except to the
extent paid by the Nuevo Trust), as and when due, regardless of any defense,
right of setoff or counterclaim which the Nuevo Trust may have or assert. The
following payments with respect to the Trust Preferred Securities to the extent
not paid by the Nuevo Trust (the "Guarantee Payments"), will be subject to the
Trust Preferred Securities Guarantee thereon (without duplication): (i) any
accrued and unpaid distributions which are required to be paid on such Trust
Preferred Securities, to the extent the Nuevo Trust shall have funds available
therefor; (ii) the redemption price set forth in the applicable Prospectus
Supplement (the "Redemption Price"), which will not be lower than the
liquidation amount, and all accrued and unpaid distributions, to the extent the
Nuevo Trust has funds available therefor, with respect to any Trust Preferred
Securities called for redemption by the Nuevo Trust and (iii) upon a voluntary
or involuntary dissolution, winding-up or termination of the Nuevo Trust (other
than in connection with the distribution of Subordinated Debt Securities to the
holders of Trust Preferred Securities or the redemption of all of the Trust
Preferred Securities), the lesser of (a) the aggregate of the liquidation amount
and all accrued and unpaid distributions on the Trust Preferred Securities to
the date of payment, to the extent the Nuevo Trust has funds available therefor,
and (b) the amount of assets of the 

                                       22
<PAGE>
 
Nuevo Trust remaining available for distribution to holders of the Trust
Preferred Securities in liquidation of the Nuevo Trust. The Company's obligation
to make a Guarantee Payment may be satisfied by direct payment of the required
amounts by the Company to the holders of Trust Preferred Securities or by
causing the Nuevo Trust to pay such amounts to such holders.

The Trust Preferred Securities Guarantee will not apply to any payment of
distributions on the Trust Preferred Securities except to the extent the Nuevo
Trust shall have funds available therefor. If the Company does not make interest
payments on the Subordinated Debt Securities purchased by the Nuevo Trust, the
Nuevo Trust will not pay distributions on the Trust Preferred Securities issued
by the Nuevo Trust and will not have funds available therefor. See "Description
Of Debt Securities - Certain Covenants of the Company." The Trust Preferred
Securities Guarantee, when taken together with the Company's obligations under
the Subordinated Debt Securities, the Indenture and the Declaration, including
its obligations to pay costs, expenses, debts and liabilities of the Nuevo Trust
(other than with respect to the Trust Securities), will provide a full and
unconditional guarantee on a subordinated basis by the Company of payments due
on the Trust Preferred Securities.

The Company has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Nuevo Trust with respect to the Trust Common
Securities (the "Trust Common Securities Guarantee") to the same  extent as the
Trust Preferred Securities Guarantee, except that upon an event of default under
the Subordinated Indenture, holders of Trust Preferred Securities shall have
priority over holders of Trust Common Securities with respect to distributions
and payments on liquidation, redemption or otherwise.

CERTAIN COVENANTS OF THE COMPANY

In the Trust Preferred Securities Guarantee, the Company will covenant that, so
long as any Trust Preferred Securities remain outstanding, if there shall have
occurred any event that would constitute an event of default under such Trust
Preferred Securities Guarantee or the Declaration of the Nuevo Trust, then (a)
the Company shall not declare or pay any dividend on, make any distributions
with respect to, or redeem, purchase or make a liquidation payment with respect
to, any of its capital stock (other than (i) purchases or acquisitions of shares
of Common Stock in connection with the satisfaction by the Company of its
obligations under any employee benefit plans, (ii) as a result of a
reclassification of the Company's capital stock or the exchange or conversion of
one class or series of the Company's capital stock for another class or series
of the Company's capital stock, or (iii) the purchase of fractional interests in
shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock of the Company or the security being converted
or exchanged) or make any guarantee payments with respect to the foregoing and
(b) the Company shall not make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem any debt securities (including
guarantees) issued by the Company which rank pari passu with or junior to the
Subordinated Debt Securities held by the Property Trustee.

MODIFICATION OF THE TRUST PREFERRED SECURITIES GUARANTEE; ASSIGNMENT

Except with respect to any changes which do not materially adversely affect the
rights of holders of Trust Preferred Securities (in which case no vote will be
required), the Trust Preferred Securities Guarantee may be amended only with the
prior approval of the holders of not less than a majority in liquidation amount
of the outstanding Trust Preferred Securities. The manner of obtaining any such
approval of holders of such Trust Preferred Securities will be as set forth in
an accompanying Prospectus Supplement. All guarantees and agreements contained
in the Trust Preferred Securities Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Company and shall inure to the
benefit of the holders of the Trust Preferred Securities then outstanding.

TERMINATION

The Trust Preferred Securities Guarantee will terminate (a) upon full payment of
the Redemption Price of all Trust Preferred Securities, (b) upon distribution of
the Subordinated Debt Securities held by the Property Trustee to the holders of
the Trust Preferred Securities or (c) upon full payment of the amounts payable
in accordance with the Declaration upon liquidation of the Nuevo Trust.  The
Trust Preferred Securities Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of Trust Preferred
Securities must restore payment of any sums paid under the Trust Preferred
Securities or the Trust Preferred Securities Guarantee. The subordination
provisions of the Subordinated Debt Securities provide that in the event payment
is made on the Subordinated Debt Securities in contravention of such provisions
such payments shall be paid over to the holders of Senior Indebtedness.

                                       23
<PAGE>
 
EVENTS OF DEFAULT

An event of default under the Trust Preferred Securities Guarantee will occur
upon (a) the failure of the Company to perform any of its payment or other
obligations thereunder or (b) if applicable, the failure by the Company to
deliver Common Stock upon an appropriate election by the holder or holders of
Trust Preferred Securities to convert the Trust Preferred Securities into shares
of Common Stock.

The holders of a majority in liquidation amount of the Trust Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Preferred Guarantee Trustee in
respect of the Trust Preferred Securities Guarantee or to direct the exercise of
any trust or power conferred upon the Preferred Guarantee Trustee under such
Trust Preferred Securities. If the Preferred Guarantee Trustee fails to enforce
such Trust Preferred Securities Guarantee, any holder of Trust Preferred
Securities may institute a legal proceeding directly against the Company to
enforce the Preferred Guarantee Trustee's rights under such Trust Preferred
Securities Guarantee, without first instituting a legal proceeding against the
Nuevo Trust, the Preferred Guarantee Trustee or any other person or entity.
Notwithstanding the foregoing, if the Company has failed to make a Guarantee
Payment, a holder of Trust Preferred Securities may directly institute a
proceeding against the Company for enforcement of the Trust Preferred Securities
Guarantee for such payment. The Company waives any right or remedy to require
that any action be brought first against the Nuevo Trust or any other person or
entity before proceeding directly against the Company.

STATUS OF THE TRUST PREFERRED SECURITIES GUARANTEE

The Trust Preferred Securities Guarantee will constitute an unsecured obligation
of the Company and will rank (i) subordinate and junior in right of payment to
all other liabilities of the Company, (ii) pari passu with the most senior
preferred or preference stock now or hereafter issued by the Company and with
any guarantee now or hereafter entered into by the Company in respect of any
preferred or preference stock of any affiliate of the Company and (iii) senior
to Common Stock. The terms of the Trust Preferred Securities provide that each
holder of Trust Preferred Securities by acceptance thereof agrees to the
subordination provisions and other terms of the Trust Preferred Securities
Guarantee relating thereto.

The Trust Preferred Securities Guarantee will constitute a guarantee of payment
and not of collection (that is, the guaranteed party may institute a legal
proceeding directly against the guarantor to enforce its rights under the
guarantee without instituting a legal proceeding against any other person or
entity).

INFORMATION CONCERNING THE PREFERRED GUARANTEE TRUSTEE

The Preferred Guarantee Trustee, prior to the occurrence of a default with
respect to the Trust Preferred Securities Guarantee, undertakes to perform only
such duties as are specifically set forth in such Trust Preferred Securities
Guarantee and, after default, shall exercise the same degree of care as a
prudent individual would exercise in the conduct of his or her own affairs.
Subject to such provisions, the Preferred Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by a Trust Preferred
Securities Guarantee at the request of any holder of the Trust Preferred
Securities, unless offered reasonable indemnity against the costs, expenses and
liabilities which might be incurred thereby.

                              PLAN OF DISTRIBUTION

The Securities may be sold by the Company, the Nuevo Trust and/or the Selling
Stockholders (i) through agents, (ii) through underwriters, (iii) through
dealers or (iv) directly to purchasers (through a specific bidding or auction
process or otherwise). In addition, the 1818 Fund may offer and sell Common
Stock on the New York Stock Exchange. The distribution of Securities may be
effected from time to time in one or more transactions at a fixed price or
prices, which may be changed, or at market prices prevailing at the time of
sale, at prices relating to such prevailing market prices or at negotiated
prices.

Offers to purchase the Securities may be solicited by agents designated by the
Company or a Selling Stockholder from time to time. Any such agent involved in
the offer or sale of the Securities will be named, and any commissions payable
by the Company or Selling Stockholder to such agent will be set forth in the
Prospectus Supplement. Unless otherwise indicated in the Prospectus Supplement,
any such agent will be acting on a best efforts basis for the period of its
appointment. Any such agent may be deemed to be an underwriter, as that term is
defined in the Securities Act, of the Securities so offered and sold.

If an underwriter or underwriters are utilized in the sale of Securities, the
Company or any Selling Stockholders selling Common Stock thereunder will execute
an underwriting agreement with such underwriter or underwriters at the time an
agreement for such sale is reached, and the names of the 

                                       24
<PAGE>
 
specific managing underwriter or underwriters, as well as any other underwriters
and the terms of the transactions, including compensation of the underwriters
and dealers, if any, will be set forth in the Prospectus Supplement, which will
be used by the underwriters to make resales of the Securities.

If a dealer is utilized in the sale of the Securities, the Company or a Selling
Stockholder will sell such Securities to the dealer, as principal. The dealer
may then resell such Securities to the public at varying prices to be determined
by such dealer at the time of resale. The name of the dealer and the terms of
the transactions will be set forth in the Prospectus Supplement relating
thereto. Offers to purchase the Securities may be solicited directly by the
Company or a Selling Stockholder and sales thereof may be made by the Company or
a Selling Stockholder directly to institutional investors or others. The terms
of any such sales, including the terms of any bidding or auction process, if
utilized, will be described in the Prospectus Supplement relating thereto.

The Securities may also be offered and sold, if so indicated in the Prospectus
Supplement, in connection with a remarketing upon their purchase, in accordance
with a redemption or repayment pursuant to their terms, or otherwise, by one or
more firms ("remarketing firms"), acting as principals for their own accounts or
as agents for the Company or a Selling Stockholder.  Any remarketing firm will
be identified and the terms of its agreement, if any, with the Company or a
Selling Stockholder and its compensation will be described in the Prospectus
Supplement. Remarketing firms may be deemed to be underwriters in connection
with the Securities remarketed thereby.

Agents, underwriters, dealers and remarketing firms may be entitled under
agreements which may be entered into with the Company or Selling Stockholders to
indemnification by the Company or Selling Stockholders against certain
liabilities, including liabilities under the Securities Act, and any such
agents, underwriters, dealers or remarketing firms, or their affiliates may be
customers of, engage in transactions with or perform services for the Company or
Selling Stockholders in the ordinary course of business.

If so indicated in the Prospectus Supplement, the Company will authorize agents
and underwriters to solicit offers by certain institutions to purchase Debt
Securities from the Company at the public offering price set forth in the
Prospectus Supplement pursuant to Delayed Delivery Contracts ("Contracts")
providing for payment and delivery on the date stated in the Prospectus
Supplement. Such 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 Debt Securities
pursuant to Contracts accepted by the Company.

                              SELLING STOCKHOLDERS

The Selling Stockholders are United Investors Management Company, a Delaware
corporation ("United") and wholly owned subsidiary of Torchmark Corporation, an
insurance and financial services holding company, and the 1818 Fund. As of
September 30, 1996, United owned 1,275,000 shares of Common Stock of Nuevo and
the 1818 Fund owned 112 shares of Common Stock and 11,220 shares of 7% Preferred
Stock convertible into approximately 863,493 shares of Common Stock. United is
registering for sale all of the shares of Common Stock owned by it and the 1818
Fund is registering for sale all of the shares of Common Stock owned by it or
issuable upon conversion of all of the 7% Preferred Stock owned by it. The
Prospectus Supplement relating to any Common Stock being offered by either
Selling Stockholder will set forth the number of shares of Common Stock being
offered for its account as well as the number of such shares and the percentage
of the outstanding Common Stock to be owned by such Selling Stockholder after
completion of the offering.

The shares of Common Stock being registered hereunder for sale by United and
1818 Fund have been registered pursuant to registration rights agreements, one
of which is between Nuevo and the 1818 Fund, dated May 28, 1992 and the other of
which is between Nuevo and Torch Energy Advisors Incorporated, dated April 4,
1996.  Torch Energy Advisors Incorporated subsequently assigned its rights under
the April 4, 1996 agreement to United. Both registration rights agreements
provide a specified number of "demand" registration rights and unlimited "piggy
back" registration rights. The Company has agreed pursuant to the registration
rights agreements to indemnify the 1818 Fund and United (as the case may be)
against certain liabilities including liabilities under the Securities Act, or
to contribute to payments the 1818 Fund or United may be required to make in
respect thereof. The Company is obligated to pay all expenses in connection with
the shares sold by 1818 Fund hereunder, excluding any underwriting discounts or
commissions. United is required to pay its pro rata share of any expenses of
demand registrations requested by it, and the Company is required to pay all
expenses of registration statements in which United participates under its piggy
back registration rights, excluding any underwriting discounts or commissions.

                                       25

The general and managing partner of the 1818 Fund is Brown Brothers Harriman &
Co., a New York partnership ("Brown Brothers"), which has designated its
partners T. Michael Long and Lawrence C. Tucker the sole and exclusive partners
having voting power and investment power with respect to the shares of Common
Stock into which the 7% Preferred Stock is convertible. Mr. Long is a director
of the Company. Brown Brothers has advised the Company that the 1818 Fund is
selling its Common Stock because of the advanced term of the 1818 Fund in
relation to its planned life.

Prior to September 30, 1996, United owned all of the capital stock of Torch
Energy Advisors Incorporated ("Torch Energy") which has rendered administrative
services to the Company since the formation of the Company in 1990 pursuant to
an administrative services agreement, as amended.  Prior to United's
sale of Torch Energy on September 30, 1996, Torch Energy distributed to United
the shares of Common Stock being registered hereunder.  Torch Energy acquired
these shares in exchange for properties sold to Nuevo in April 1996.  For
services rendered in connection with the acquisition of oil and gas properties
in California during April 1996, the Company paid Torch Energy a fee of $10
million.  Prior to September 30, 1996, J.P. Bryan, a director of the Company,
was also a director of Torchmark Corporation.  United has advised the Company
that it is selling its shares pursuant to its previously announced liquidation
of its energy-related investments.

          This Prospectus is not the exclusive means for resale of any Common
Stock of the Selling Stockholders registered hereunder.  For example, the 1818
Fund may also sell Common Stock owned by it pursuant to Rule 144 under the
Securities Act.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the General Corporation Law of the State of Delaware,
pursuant to which the Company is incorporated, provides generally and in
pertinent part that a Delaware corporation may indemnify its directors and
officers against expenses, judgments, fines, and settlements actually and
reasonably incurred by them in connection with any civil, criminal,
administrative, or investigative suit or action except actions by or in the
right of the corporation if, in connection with the matters in issue, they acted
in good faith and in a manner they reasonably believed to be in or not opposed
to the best interests of the corporation, and in connection with any criminal
suit or proceeding, if in connection with the matters in issue, they had no
reasonable cause to believe their conduct was unlawful.  Section 145 further
provides that in connection with the defense or settlement of any action by or
in the right of the corporation, a Delaware corporation may indemnify its
directors and officers against expenses actually and reasonably incurred by them
if, in connection with the matters in issue, they acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation, except that no indemnification may be made in respect of any
claim, issue, or matter as to which such person has been adjudged liable to the
corporation unless the Delaware Court of Chancery or other court in which such
action or suit is brought approves such indemnification.  Section 145 further
permits a Delaware corporation to grant its directors and officers additional
rights of indemnification through bylaw provisions and otherwise, and or
purchase indemnity insurance on behalf of its directors and officers.  Article
Nine of the Certificate of Incorporation of the Company and Article VII the

ITEM 17.  UNDERTAKINGS

The undersigned registrant hereby undertakes:

     1.   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 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 end 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 a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

     (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 (1)(i) and (1)(ii) of this section do
not apply if the registration statement is on Form S-3, Form S-8 or Form F-3,
and the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to section 13 or section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

     (2) 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.

     (3) 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.

     The undersigned registrant undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to section 13(a) or section 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.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable.  In the event that claims for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer, or controlling person of
the Company 

                                     II-4
<PAGE>
 
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Company 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 Securities Act of 1933 and will be governed by the
final adjudication of such issue.

     The undersigned registrant hereby undertakes that:

     (1)  For purposes 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 shall be deemed to be part of this registration
statement as of the time it was declared effective.

     (2)  For purposes 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.

by Holders of Securities of such series, provided that the Company may not set a
record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or
direction referred to in the next paragraph.  If any record date is set pursuant
to this paragraph, the Holders of Outstanding Securities of the relevant series
on such record date, and no other Holders, shall be entitled to take the
relevant action, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on
or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date.  Nothing in
this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken.  Promptly
after any record date is set pursuant to this paragraph, the Company, at its own

Section 502, (3) any request to institute proceedings referred to in Section

respect to Securities of such series. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities of such series on such record
date, and no other Holders, shall be entitled to join in such notice,
declaration, request or direction, whether or not such Holders remain Holders
after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of Outstanding Securities of such series on
such record date. Nothing in this paragraph shall be construed to prevent the
Trustee from setting a new record date for any action for which a record date
has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be canceled
and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee,
at the Company's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Company
in writing and to each Holder of Securities of the relevant series in the manner
set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date.  If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph.  Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

     SECTION 105.  NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention: Corporate
     Trust Administration.

          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing 

                                      -12-
<PAGE>
 
     and mailed, first-class postage prepaid, to the Company addressed to it at
     the address of its principal office specified in the first paragraph of
     this instrument or at any other address previously furnished in writing to
     the Trustee by the Company.

     SECTION 106.  NOTICE TO HOLDERS; WAIVER.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

     SECTION 107.  CONFLICT WITH TRUST INDENTURE ACT.

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control.  If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

     SECTION 108.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

     SECTION 109.  SUCCESSORS AND ASSIGNS.

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

     SECTION 110.  SEPARABILITY CLAUSE.

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

     SECTION 111.  BENEFITS OF INDENTURE.

                                      -13-
<PAGE>
 
     Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder
and the Holders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

     SECTION 112.  GOVERNING LAW.

     This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.

     SECTION 113.  LEGAL HOLIDAYS.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

                                  ARTICLE TWO

such action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the Company
Order contemplated by Section 303 for the authentication and delivery of such
Securities.

     The definitive Securities shall be printed, lithographed or engraved on

     The Trustee's certificates of authentication shall be in substantially the
following form:

          This is one of the Securities of the series designated therein
     referred to in the within-mentioned Indenture.

     SECTION 203.  FORM OF LEGEND FOR GLOBAL SECURITIES.

     Unless otherwise specified as contemplated by Section 301 for the
Securities evidenced thereby, every Global Security authenticated and delivered
hereunder shall bear a legend in substantially the following form:

     THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
     HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A
     NOMINEE THEREOF.  THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART
     FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN
     PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH
     DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES
     DESCRIBED IN THE INDENTURE.

     SECTION 204.  FORM OF CONVERSION NOTICE.

     The form of conversion notice for the conversion of Securities into shares
of Common Stock or other securities of the Company shall be in substantially the
form included with the applicable form of Securities as shall be established
pursuant to Section 201 hereinabove.

     SECTION 205.  SECURITIES IN GLOBAL FORM.

     If Securities of any series are issuable as Global Securities, as specified
as contemplated by Section 301, then, notwithstanding the provisions of Section
301, any such Security shall represent such of the Outstanding Securities of
such series as shall be specified therein and may provide that it shall
represent the aggregate amount of Outstanding Securities of such series from
time to time endorsed thereon and that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be reduced
to reflect exchanges.  Any endorsement of a Global Security to reflect the
amount, or any increase or decrease in the amount, of Outstanding Securities of
such series represented thereby shall be made by the Trustee in such manner and
upon instructions given by such Person or Persons as shall be specified therein
or in the Company Order to be delivered to the Trustee pursuant to Section 303
or Section 304.  Subject to the provisions of Section 303 and, if applicable,
Section 304, the Trustee shall deliver and redeliver any Global Security in the
manner and upon instructions given by the Person or Persons specified therein or
in the applicable Company Order.  If a Company Order pursuant to Section 303 or
304 has been, or simultaneously is, delivered, any instructions by the Company
with respect to endorsement or delivery or redelivery of a Global Security shall
be in writing but need not comply with Section 102 and need not be accompanied
by an Opinion of Counsel.

                                      -15-
<PAGE>
 
     The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security
with written instructions (which need not comply with Section 102 and need not
be accompanied by an Opinion of Counsel) with regard to the reduction in the
principal amount of Securities represented thereby, together with the written
statement contemplated by the last sentence of Section 303.

     Notwithstanding the provisions of Sections 201 and 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium and interest on any Global Security shall be made to the Person or
Persons specified therein.

     Notwithstanding the provisions of Section 308 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company and
the Trustee shall treat a Person as the Holder of such principal amount of
Outstanding Securities represented by a Global Security as shall be specified in
a written statement of the Holder of such Global Security.

<PAGE>
 
     All Securities of any one series shall be substantially identical except as
to denomination and except as may otherwise be provided in or pursuant to the
Board Resolution referred to above and (subject to Section 303) set forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

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

     SECTION 302.  DENOMINATIONS.

     The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof.

     SECTION 303.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its Vice Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries.  The signature of any of these
officers on the Securities may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities.  If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
prior to authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

          (1) if the form of such Securities has been established by or pursuant
     to Board Resolution as permitted by Section 201, that such form has been
     established in conformity with the provisions of this Indenture;

          (2) if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 301, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

                                      -19-
<PAGE>
 
          (3) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and similar laws of general applicability
     relating to or affecting creditors' rights and to general equity
     principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.  Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

     SECTION 304.  TEMPORARY SECURITIES.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder.  Upon surrender for cancellation of any one or 

                                      -20-
<PAGE>
 
more temporary Securities of any series, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

     SECTION 305.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.  The Security Registrar shall be
entitled to the rights and protections extended to the Trustee hereunder.

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

     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency.  Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

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

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

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     If the Securities of any series (or of any series and specified tenor) are
to be redeemed in part, the Company shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption under 

                                      -21-
<PAGE>
 
Section 1103 and ending at the close of business on the day of such mailing, or
(B) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

     The provisions of Clauses (1), (2), (3) and (4) below shall apply only  to
Global Securities:

          (1) Each Global Security authenticated under this Indenture shall be
     registered in the name of the Depositary designated for such Global
     Security or a nominee thereof and delivered to such Depositary or a nominee
     thereof or custodian therefor, and each such Global Security shall
     constitute a single Security for all purposes of this Indenture.

          (2) Notwithstanding any other provision in this Indenture, no Global
     Security may be exchanged in whole or in part for Securities registered,
     and no transfer of a Global Security in whole or in part may be registered,
     in the name of any Person other than the Depositary for such Global
     Security or a nominee thereof unless (A) such Depositary (i) has notified
     the Company that it is unwilling or unable to continue as Depositary for
     such Global Security or (ii) has ceased to be a clearing agency registered
     under the Exchange Act, (B) there shall have occurred and be continuing an
     Event of Default with respect to such Global Security or (C) there shall
     exist such circumstances, if any, in addition to or in lieu of the
     foregoing as have been specified for this purpose as contemplated by
     Section 301.

          (3) Subject to Clause (2) above, any exchange of a Global Security for
     other Securities may be made in whole or in part, and all Securities issued
     in exchange for a Global Security or any portion thereof shall be
     registered in such names as the Depositary for such Global Security shall
     direct.

          (4) Every Security authenticated and delivered upon registration of
     transfer of, or in exchange for or in lieu of, a Global Security or any
     portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
     1107 or otherwise, shall be authenticated and delivered in the form of, and
     shall be, a Global Security, unless such Security is registered in the name
     of a Person other than the Depositary for such Global Security or a nominee
     thereof.

     SECTION 306.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

                                      -22-
<PAGE>
 
     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Company or
the Trustee may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     SECTION 307.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner.  The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this Clause provided.  Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment.  The Trustee shall
     promptly notify the Company of such 

                                      -23-
<PAGE>
 
     Special Record Date and, in the name and at the expense of the Company,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be given to each Holder of Securities
     of such series in the manner set forth in Section 106, not less than 10
     days prior to such Special Record Date. Notice of the proposed payment of
     such Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following Clause (2).

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

     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.

     In the case of any Security which is converted into Common Stock of the
Company after any Regular Record Date and on or prior to the next succeeding
Interest Payment Date (other than any Security whose Maturity is prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion, and such interest (whether or not punctually paid or duly provided
for) shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security which is converted, interest whose Stated
Maturity is after the date of conversion of such Security shall not be payable.

     SECTION 308.  PERSONS DEEMED OWNERS.

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

     SECTION 309.  CANCELLATION.

     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for 

                                      -24-
<PAGE>
 
delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly canceled by the Trustee. No Securities
shall be authenticated in lieu of or in exchange for any Securities canceled as
provided in this Section, except as expressly permitted by this Indenture. All
canceled Securities held by the Trustee shall be disposed of as directed by a
Company Order.

     SECTION 310.  COMPUTATION OF INTEREST.

     Except as otherwise specified as contemplated by Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a 360-day year of twelve 30-day months.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

     SECTION 401.  SATISFACTION AND DISCHARGE OF INDENTURE.

     This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when either (A) all Securities theretofore
authenticated and delivered (other than (i) Securities which have been
destroyed, lost or stolen and which have been replaced or paid as provided in
Section 306 and (ii) 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, as provided in Section
1003) have been delivered to the Trustee for cancellation; or (B) all such
Securities not theretofore delivered to the Trustee for cancellation (i) have
become due and payable, or (ii) will become due and payable at their Stated
Maturity within one year, or (iii) are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company, and
the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to
be deposited with the Trustee as trust funds in trust for the purpose money in
an amount sufficient to pay and discharge the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation, for
principal and any premium and interest to the date of such deposit (in the case
of Securities which have become due and payable) or to the Stated Maturity or
Redemption Date, as the case may be;

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

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

     Notwithstanding the satisfaction and discharge of this Indenture, the
rights of the Trustee under Sections 507(3), 601 and 603, the obligations of the
Company to the Trustee under Section 607, the obligations of the Trustee to any
Authenticating Agent 

                                      -25-
<PAGE>
 
under Section 614 and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of Clause (l) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

     SECTION 402.  APPLICATION OF TRUST MONEY.

     Subject to the provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.
Money deposited pursuant to this Section not in violation of this Indenture
shall not be subject to claims of the holders of Senior Indebtedness under
Article Fifteen hereof.

                                  ARTICLE FIVE

                                   REMEDIES

     SECTION 501.  EVENTS OF DEFAULT.

     "Event of Default", wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

          (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 30 days (whether or not such payment is prohibited by the
     subordination provisions set forth in Article Fifteen hereof); provided,
     however, that a valid extension of an interest payment period by the
     Company in accordance with the terms of any indenture supplemental hereto
     shall not constitute a default in the payment of interest for this purpose;
     or

          (2) default in the payment of the principal of or any premium on any
     Security of that series at its Maturity (whether or not such payment is
     prohibited by the subordination provisions set forth in Article Fifteen
     hereof); or

          (3) default in the deposit of any sinking fund payment, when and as
     due by the terms of a Security of that series; or

          (4) if the Securities of that series are convertible or exchangeable
     into or for shares of Common Stock of the Company or other securities, cash
     or other property pursuant to any supplemental indenture, Board Resolution
     or other instrument authorizing Securities of that series, failure by the
     Company to convert such Securities (whether or not such conversion or
     exchange is prohibited by the subordination provisions set forth in Article
     Fifteen hereof); or

          (5) default in the performance, or breach, of any covenant or warranty
     of the Company in this Indenture (other than a covenant or warranty a
     default in 

                                      -26-
<PAGE>
 
     whose performance or whose breach is elsewhere in this Section specifically
     dealt with or which has expressly been included in this Indenture solely
     for the benefit of series of Securities other than that series), and
     continuance of such default or breach for a period of 60 days after there
     has been given, by registered or certified mail, to the Company by the
     Trustee or to the Company and the Trustee by the Holders of at least 25% in
     principal amount of the Outstanding Securities of that series a written
     notice specifying such default or breach and requiring it to be remedied
     and stating that such notice is a "Notice of Default" hereunder; or

          (6) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or (B) a decree or order adjudging the
     Company a bankrupt or insolvent, or approving as properly filed a petition
     seeking reorganization, arrangement, adjustment or composition of or in
     respect of the Company under any applicable Federal or State law, or
     appointing a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Company or of any substantial
     part of its property, or ordering the winding up or liquidation of its
     affairs, and the continuance of any such decree or order for relief or any
     such other decree or order unstayed and in effect for a period of 60
     consecutive days; or

          (7) the commencement by the Company of a voluntary case or proceeding
     under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or State bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it of a petition or answer or consent seeking reorganization or relief
     under any applicable Federal or State law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a
     custodian, receiver, liquidator, assignee, trustee, sequestrator other

     admission by it in writing of its inability to pay its debts generally as
     they become due, or the taking of corporate action by the Company in
     furtherance of any such action; or

          (8) in the event Securities of that series are issued to the Nuevo
     Trust or a trustee of such trust in connection with the issuance of Trust
     Securities by the Nuevo Trust, the Nuevo Trust shall have voluntarily or
     involuntarily dissolved, wound-up its business or otherwise terminated its
     existence except in connection with (A) the distribution of Securities of
     that series to holders of Trust Securities in liquidation of their interest
     in the Nuevo Trust, (B) the redemption of all of the outstanding Trust
     Securities of the Nuevo Trust or (C) certain mergers, consolidations or
     amalgamations, each as permitted by the Declaration of the Nuevo Trust; or

          (9) any other Event of Default provided with respect to Securities of
     that series.

                                      -27-
<PAGE>
 
     SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default (other than an Event of Default specified in Section
501(6) or 501(7)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable; provided, however, that the Holders of a majority
in aggregate principal amount of Securities of such series then Outstanding may
rescind or annul such declaration and its consequences by objecting in writing
within 30 days of such declaration.  If an Event of Default specified in Section
501(6) or 501(7) with respect to Securities of any series at the time
Outstanding occurs, the principal amount of all the Securities of that series
(or, if any Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified by
the terms thereof) shall automatically, and without any declaration or other
action on the part of the Trustee or any Holder, become immediately due and
payable.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

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

               (A)  all overdue interest on all Securities of that series,

               (B)  the principal of (and premium, if any, on) any Securities of
          that series which have become due otherwise than by such declaration
          of acceleration and any interest thereon at the rate or rates
          prescribed therefor in such Securities,

               (C)  to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

               (D)  all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel;

     and

          (2)  all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have 

                                      -28-
<PAGE>
 
     become due solely by such declaration of acceleration, have been cured or
     waived as provided in Section 513.

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

     SECTION 503.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

     The Company covenants that if:

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 30 days, or

          (2) default is made in the payment of the principal of (or premium, if
     any, on) any Security at the Maturity thereof, the Company will, upon
     demand of the Trustee, pay to it, for the benefit of the Holders of such
     Securities, the whole amount then due and payable on such Securities for
     principal and any premium and interest and, to the extent that payment of
     such interest shall be legally enforceable, interest on any overdue
     principal and premium and on any overdue interest, at the rate or rates
     prescribed therefor in such Securities and if such Securities are held by a
     Nuevo Trust or a trustee of such trust, without duplication of any other
     amounts paid by such Nuevo Trust or trustee in respect thereof, upon
     overdue installments of interest at the rate per annum expressed in such
     Securities; and, in addition thereto, such further amount as shall be
     sufficient to cover the costs and expenses of collection, including the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel.

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

     SECTION 504.  TRUSTEE MAY FILE PROOF OF CLAIM.

     In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding.  In
particular, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute the
same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

                                      -29-
<PAGE>
 
     No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

     SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

     SECTION 506.  APPLICATION OF MONEY COLLECTED.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 607;

     SECOND: To the payment of all Senior Indebtedness of the Company to the
required by Article Fifteen hereof;

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

     FOURTH: To the payment of the remainder, if any, to the Company.

     SECTION 507.  LIMITATION ON SUITS.

     No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless:

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

                                      -30-
<PAGE>
 
          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

     SECTION 508.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
AND INTEREST.

     Notwithstanding any other provision in this Indenture, but subject to
Article Fifteen of this Indenture, the Holder of any Security shall have the
right, which is absolute and unconditional, to receive payment of the principal
of and any premium and (subject to Section 307) interest on such Security on the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

     SECTION 509.  RESTORATION OF RIGHTS AND REMEDIES.

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

     SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given 

                                      -31-
<PAGE>
 
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

     SECTION 511.  DELAY OR OMISSION NOT WAIVER.

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

     SECTION 512.  CONTROL BY HOLDERS. 

     The holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture,

          (2) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     connection therewith, and

          (3) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

     SECTION 513.  WAIVER OF PAST DEFAULTS.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default:

          (1) in the payment of the principal of or any premium or interest on
     any Security of such series, or

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

provided, however, that if the Securities of such series are held by the Nuevo
Trust or a trustee of such trust, such waiver or modification to such waiver
shall not be effective until the holders of a majority in liquidation preference
of Trust Securities of the Nuevo Trust shall have consented to such waiver or
modification to such waiver; provided, further, that if the consent of the
Holder of each Outstanding Security of such series is required, such waiver
shall not be effective until each holder of the Trust Securities of the Nuevo
Trust shall have consented to such waiver.

                                      -32-
<PAGE>
 
     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

     SECTION 514.  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, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.

     SECTION 515.  WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

                                  ARTICLE SIX

                                  THE TRUSTEE

     SECTION 601.  CERTAIN DUTIES AND RESPONSIBILITIES.

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.  Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

     SECTION 602.  NOTICE OF DEFAULTS. 

     If a default occurs hereunder with respect to Securities of any series, the
Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(5) with respect to Securities of such series, no such notice to Holders
shall be given until at least 60 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or 

                                      -33-
<PAGE>
 
after notice or lapse of time or both would become, an event of default with
respect to securities of such series.

     SECTION 603.  CERTAIN RIGHTS OF TRUSTEE.

     Subject to the provisions of Section 601:

          (1) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document believed by it to be genuine and to have been signed or presented

          (3) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

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

          (5) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

          (6) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney; and

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

     SECTION 604.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

                                      -34-
<PAGE>
 
     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness.  The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities.  Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

     SECTION 605.  MAY HOLD SECURITIES.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

     SECTION 606.  MONEY HELD IN TRUST.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law.  The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

     SECTION 607.  COMPENSATION AND REIMBURSEMENT.

     The Company agrees:

          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel), except any such expense,
     disbursement or advance as may be attributable to its negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the costs and expenses of
     defending itself against any claim or liability in connection with the
     exercise or performance of any of its powers or duties hereunder.

     SECTION 608.  CONFLICTING INTERESTS.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.  To the extent
permitted by such Act, the Trustee shall not be deemed 

                                      -35-
<PAGE>
 
to have a conflicting interest by virtue of being a trustee under this Indenture
with respect to Securities of more than one series.

     SECTION 609.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series.  Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000.  If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

     SECTION 610.  RESIGNATION AND REMOVAL, APPOINTMENT OF SUCCESSOR.

     No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or
more series by giving written notice thereof to the Company.  If the instrument
of acceptance by a successor Trustee required by Section 611 shall not have been
delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

     The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

     If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a 

                                      -36-
<PAGE>
 
bona fide Holder of a Security for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee with respect to all Securities and the
appointment of a successor Trustee or Trustees.

     If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect to
the Securities of one or more series, the Company, by a Board Resolution, shall
promptly appoint a successor Trustee or Trustees with respect to the Securities
of that or those series (it being understood that any such successor Trustee may
be appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 611.  If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent
supersede the successor Trustee appointed by the Company.  If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 611, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

     The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders of
Securities of such series in the manner provided in Section 106.  Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

     SECTION 611.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

     In case of the appointment hereunder of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and 

                                      -37-
<PAGE>
 
deliver an indenture supplemental hereto wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.

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

     SECTION 612.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any Person into which the Trustee may be merged or converted or with which
it may be consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any Person succeeding to
all or substantially all the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided such Person shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto.  In case
any Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

     SECTION 613.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. 

     If and when the Trustee shall be or become a creditor of the Company (or 
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the trust 

                                      -38-
<PAGE>
 
indenture act regarding the collection of claims against the company (or any
such other obligor).

     SECTION 614.  APPOINTMENT OF AUTHENTICATING AGENT.

     The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a Person organized and doing
business under the laws of the United States of America, any State thereof or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any Person into which an Authenticating Agent may be merged or converted or
with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Authenticating Agent shall be a party,
or any Person succeeding to the corporate agency or corporate trust business of
an Authenticating Agent, shall continue to be an Authenticating Agent, provided
such Person shall be otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                                      -39-
<PAGE>
 
     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

     any indebtedness which becomes an obligation of the Company or any
     Subsidiary as a result of such transaction as having been incurred by the

     series) or to surrender any right or power herein conferred upon the
     Company; or

                                      -42-

     solely for the benefit of such series); or

          (4)  to add to or change any of the provisions of this Indenture to
     such extent as shall be necessary to permit or facilitate the issuance of
     Securities in bearer form, registrable or not registrable as to principal,

     indenture and entitled to the benefit of such provision nor (ii) modify the
     rights of the Holder of any such Security with respect to such provision or
     (B) shall become effective only when there is no such Security Outstanding;
     or

          (8)  to make provision with respect to the conversion rights of
     Holders pursuant to the requirements of Article Fourteen hereof, including
     providing for the conversion of the Securities into any security or
     property (other than the Common Stock of the Company); or

          (9)  to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture, provided that such action pursuant
     to this Clause (9) shall not adversely affect the interests of the Holders
     of Securities of any series in any material respect.

     SECTION 902.  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; 

                                      -43-
<PAGE>
 
provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Outstanding Security affected thereby:

          (1)  change the Stated Maturity of the principal of, or any
     installment of principal of or interest on, any Security, or reduce the
     principal amount thereof or the rate of interest thereon or any premium
     payable upon the redemption thereof, or reduce the amount of the principal
     of an Original Issue Discount Security or any other Security which would be
     due and payable upon a declaration of acceleration of the Maturity thereof
     pursuant to Section 502, or adversely affect any right of repayment at the
     option of a Holder of any Security, or reduce the amount of, or postpone
     the date fixed for, the payment of any sinking fund or analogous
     obligation, or change any Place of Payment where, or the coin or currency
     in which, any Security or any premium or interest thereon is payable, or
     impair the right to institute suit for the enforcement of any such payment
     on or after the Stated Maturity thereof (or, in the case of redemption, on
     or after the Redemption Date), or

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

          (3)  modify any of the provisions of this Section, Section 513 or
     Section 1008, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1008, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611 and 901(7), or

          (4)  make any change that adversely affects the right to convert any
     Security of any series as provided in Article Fourteen hereof or pursuant
     to Section 301 (except as permitted by Section 901) or decrease the
     conversion rate or increase the conversion price of any such Security of
     such series, or

          (5)  make any change in Article Fifteen hereof that adversely affects
     the rights of any Holders of Outstanding Securities of such series.

If the Securities of such series are held by a Nuevo Trust or a trustee of such
trust, such supplemental indenture shall not be effective until the holders of a
majority in liquidation preference of Trust Securities of the applicable Trust
shall have consented to such supplemental indenture; provided, that if the
consent of the Holder of each Outstanding Security of such series is required,
such supplemental indenture shall not be effective until each holder of the
Trust Securities of the applicable Nuevo Trust shall have consented to such
supplemental indenture.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of 

                                      -44-
<PAGE>
 
Securities of such series with respect to such covenant or other provision,
shall be deemed not to affect the rights under this Indenture of the Holders of
Securities of any other series.

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

     SECTION 903.  EXECUTION OF SUPPLEMENTAL INDENTURES.

     Prior to executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trust created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture.  The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     SECTION 904.  EFFECT OF SUPPLEMENTAL INDENTURES

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder

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

     SECTION 906.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

                                   COVENANTS

     SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

<PAGE>
 
     SECTION 1002.  MAINTENANCE OF OFFICE OR AGENC

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer, exchange or conversion and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served.  The Company will give prompt 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
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes.  The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

     SECTION 1003.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of or any premium
or interest on any Securities of that series, deposit with a Paying Agent a sum
sufficient to pay such amount, such sum to be held as provided by the Trust
Indenture Act, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will (1) comply with the provisions of the
Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

                                      -46-
<PAGE>
 
     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, The City of New York, 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, any unclaimed balance of such money then remaining
will be repaid to the Company.  The Paying Agent shall be entitled to the rights
and protections extended to the Trustee hereunder.

     SECTION 1004.  STATEMENT BY OFFICERS AS TO DEFAULT.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

     SECTION 1005.  EXISTENCE.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

     SECTION 1006.  MAINTENANCE OF PROPERTIES. 

    The Company will cause all properties used or useful in the conduct of its
business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in 

                                      -47-
<PAGE>
 
the judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.

     SECTION 1007.  PAYMENT OF TAXES AND OTHER CLAIMS.

     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (1) all taxes, assessments and governmental
charges levied or imposed upon the Company or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary, and (2) all lawful claims
for labor, materials and supplies which, if unpaid, might by law become a lien
upon the property of the Company or any Subsidiary; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

     SECTION 1008.  WAIVER OF CERTAIN COVENANTS.

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series, the Company may, with respect to the Securities of any series,
omit in any particular instance to comply with any term, provision or condition
set forth in any covenant provided pursuant to Section 301(20), 901(2) or 901(6)
for the benefit of the Holders of such series or in any of Sections 1006, 1007
and 1009, if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series shall,
by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

     SECTION 1009.  COVENANTS AS TO NUEVO TRUST.

     In the event Securities are issued to the Nuevo Trust or a trustee of such
trust in connection with the issuance of Trust Securities by the Nuevo Trust,
for so long as such Trust Securities remain outstanding, the Company will (1)
maintain 100% direct or indirect ownership of the Common Securities of the Nuevo
Trust; provided, however, that any permitted successor of the Company under the
Indenture may succeed to the Company's ownership of the Common Securities, (2)
use its reasonable efforts to cause the Nuevo Trust (A) to remain a statutory
business trust, except in connection with a distribution of Securities of such
series to the holders of Trust Securities in liquidation of the Nuevo Trust, the
redemption of all of the Trust Securities of the Nuevo Trust, or certain
mergers, consolidations or amalgamations, each as permitted by the Declaration
of the Nuevo Trust, and (B) to continue to be classified as a grantor trust for
United States federal income tax purposes and (3) to use its reasonable efforts
to cause each holder of Trust Securities to be treated as owning an undivided
beneficial interest in the Securities of such series.

a Board Resolution or in another manner specified as contemplated by Section 301

of less than all the Securities of any series (including any such redemption
affecting only a single Security), the Company shall, at least 60 days prior to
the Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such series to be redeemed and, if applicable,
of the tenor of the Securities to be redeemed.  In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption

Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

     SECTION 1103.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.  If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for
partial redemption as aforesaid, the principal amount thereof to be redeemed.

     The provisions of the two preceding paragraphs shall not apply with respect
to any redemption affecting only a single Security, whether such Security is to
be redeemed in whole or in part.  In the case of any such redemption in part,
the unredeemed portion of the principal amount of the Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.

                                      -49-

     If Securities of any series selected for partial redemption are converted
in part before termination of the conversion right with respect to the portion
of the Securities of such series so selected, the converted portion of the
Securities of such series shall be deemed (so far as may be) to be the portion
selected for redemption.  Securities (or portions thereof) which have been
converted during a selection of Securities of such series to be redeemed shall
be treated by the Trustee as Outstanding for the purpose of such selection.  In
any case where more than one Security of such series is registered in the same
name, the Trustee in its discretion may treat the aggregate principal amount so
registered as if it were represented by one Security of such series.

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

     SECTION 1104.  NOTICE OF REDEMPTION.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  if less than all the Outstanding Securities of any series
     consisting of more than a single Security are to be redeemed, the
     identification (and, in the case of partial redemption of any such
     Securities, the principal amounts) of the particular Securities to be
     redeemed and, if less than all the Outstanding Securities of any series
     consisting of a single Security are to be redeemed, the principal amount of
     the particular Security to be redeemed,

          (4)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5)  the place or places where each such Security is to be surrendered
     for payment of the Redemption Price,

          (6)  that the redemption is for a sinking fund, if such is the case,
     and

          (7)  if applicable, the conversion rate or price, the date on which
     the right to convert the Securities of such series to be redeemed will
     terminate and the place or places where such Securities may be surrendered
     for conversion.

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

                                      -50-

     SECTION 1105.  DEPOSIT OF REDEMPTION PRICE.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.

     If any Security called for redemption is converted into Common Stock of the
Company, any money deposited with the Trustee or with any Paying Agent or so
segregated and held in trust for the redemption of such Security shall (subject
to any right of the Holder of such Security or any Predecessor Security to
receive interest as provided in the last paragraph of Section 307) be paid to
the Company upon Company Request or, if then held by the Company, shall be
discharged from such trust.

     SECTION 1106.  SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

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

     SECTION 1107.  SECURITIES REDEEMED IN PART

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 SINKING FUNDS

     SECTION 1201.  APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment", and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund payment".  If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202.  Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

     SECTION 1202.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any sinking fund payment with respect
to any Securities of such series required to be made pursuant to the terms of
such Securities as and to the extent provided for by the terms of such
Securities; provided that the Securities to be so credited have not been
previously so credited.  The Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption Price, as specified
in the Securities so to be redeemed, for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

     SECTION 1203.  REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less than 45 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered.  Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104.  Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                               ARTICLE THIRTEEN

                      DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 1301.  COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT
DEFEASANCE.

     The Company may elect, at its option at any time, to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or 1303, in accordance with any applicable requirements provided
pursuant to Section 301 and upon compliance with the conditions set forth below
in this Article.  Any such election shall be evidenced by a Board Resolution or
in another manner specified as contemplated by Section 301 for such Securities.

     SECTION 1302.  DEFEASANCE AND DISCHARGE

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance").  For this purpose, such Defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Company's obligations with respect to such Securities under Sections 304, 305,
306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (4) this Article.  Subject to compliance with this
Article, the Company may exercise its option (if any) to have this Section
applied to any Securities notwithstanding the prior exercise of its option (if
any) to have Section 1303 applied to such Securities.

     SECTION 1303.  COVENANT DEFEASANCE.

Upon the Company's exercise of its option (if any) to have this Section applied
to any Securities or any series of Securities, as the case may be, (1) the
Company shall be released from its obligations under Sections 1006, 1007 and
1009, and any covenants provided pursuant to Section 301(20), 901(2) or 901(6)
for the benefit of the Holders of such Securities and (2) the occurrence of any
event specified in Sections 501(5) (with respect to any of Sections 1006, 1007
and 1009, and any such covenants provided pursuant to Section 301(20), 901(2) or
901(6)) and 501(9) shall be deemed not to be or result in an Event of Default,
in each case with respect to such Securities as provided in this Section on and
after the date the conditions set forth in Section 1304 are satisfied
(hereinafter called "Covenant Defeasance").  For this purpose, such Covenant
Defeasance means that, with respect to such Securities, 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 specified Section (to the extent so specified
in the case of Section 501(5) and 501(8)), 

                                      -53-

whether directly or indirectly by reason of any reference elsewhere herein to
any such Section or by reason of any reference in any such Section to any other
provision herein or in any other document, but the remainder of this Indenture
and such Securities shall be unaffected thereby.

     SECTION 1304.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be:

          (1)  The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee which satisfies the
     requirements contemplated by Section 609 and agrees to comply with the
     provisions of this Article applicable to it) as trust funds in trust for
     the purpose of making the following payments, specifically pledged as
     security for, and dedicated solely to, the benefits of the Holders of such
     Securities, (A) money in an amount, or (B) U.S. Government Obligations
     which through the scheduled payment of principal and interest in respect
     thereof in accordance with their terms will provide, not later than one day
     before the due date of any payment, money in an amount, or (C) a
     combination thereof, in each case sufficient, in the opinion of a
     nationally recognized firm of independent public accountants expressed in a
     written certification thereof delivered to the Trustee, to pay and
     discharge, and which shall be applied by the Trustee (or any such other
     qualifying trustee) to pay and discharge, the principal of and any premium
     and interest on such Securities on the respective Stated Maturities, in
     accordance with the terms of this Indenture and such Securities.  As used
     herein, "U.S. Government Obligation" means (x) any security which is (i) a
     direct obligation of the United States of America for the payment of which
     the full faith and credit of the United States of America is pledged or
     (ii) an obligation of a Person controlled or supervised by and acting as an
     agency or instrumentality of the United States of America the payment of
     which is unconditionally guaranteed as a full faith and credit obligation
     by the United States of America, which, in either case (i) or (ii), is not
     callable or redeemable at the option of the issuer thereof, and (y) any
     depository receipt issued by a bank (as defined in Section 3(a)(2) of the
     Securities Act) as custodian with respect to any U.S. Government Obligation
     which is specified in Clause (x) above and held by such bank for the
     account of the holder of such depository receipt, or with respect to any
     specific payment of principal of or interest on any U.S. Government
     Obligation which is so specified and held, provided that (except as
     required by law) such custodian is not authorized to make any deduction
     from the amount payable to the holder of such depository receipt from any
     amount received by the custodian in respect of the U.S. Government
     Obligation or the specific payment of interest evidenced by such depository
     receipt.

          (2)  In the event of an election to have Section 1302 apply to any
     Securities or any series of Securities, as the case may be, the Company
     shall have delivered to the Trustee an Opinion of Counsel stating that (A)
     the Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date of this instrument, there
     has been a change in the applicable Federal income tax law, in either case
     (A) or (B) to the effect that, and based thereon such opinion shall confirm
     that, the Holders of such Securities will not recognize gain or loss for
     Federal income tax purposes as a result of the 

                                      -54-
<PAGE>
 
     deposit, Defeasance and discharge to be effected with respect to such
     Securities and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would be the case if such
     deposit, Defeasance and discharge were not to occur.

          (3)  In the event of an election to have Section 1303 apply to any
     Securities or any series of Securities, as the case may be, the Company
     shall have delivered to the Trustee an Opinion of Counsel to the effect
     that the Holders of such Securities will not recognize gain or loss for
     Federal income tax purposes as a result of the deposit and Covenant
     Defeasance to be effected with respect to such Securities and will be
     subject to Federal income tax on the same amounts, in the same manner and
     at the same times as would be the case if such deposit and Covenant
     Defeasance were not to occur.

          (4)  The Company shall have delivered to the Trustee an Officer's
     Certificate to the effect that neither such Securities nor any other
     Securities of the same series, if then listed on any securities exchange,
     will be delisted as a result of such deposit.

          (5)  No event which is, or after notice or lapse of time or both would
     become, an Event of Default with respect to such Securities or any other
     Securities shall have occurred and be continuing at the time of such
     deposit or, with regard to any such event specified in Sections 501(6) and
     (7), at any time on or prior to the 90th day after the date of such deposit
     (it being understood that this condition shall not be deemed satisfied
     until after such 90th day).

          (6)  Such Defeasance or Covenant Defeasance shall not cause the
     Trustee to have a conflicting interest within the meaning of the Trust
     Indenture Act (assuming all Securities are in default within the meaning of
     such Act).

          (7)  Such Defeasance or Covenant Defeasance shall not result in a
     breach or violation of, or constitute a default under, any other agreement
     or instrument to which the Company is a party or by which it is bound.

          (8)  Such Defeasance or Covenant Defeasance shall not result in the
     trust arising from such deposit constituting an investment company within
     the meaning of the Investment Company Act unless such trust shall be
     registered under such Act or exempt from registration thereunder.

          (9)  The Company shall have delivered to the Trustee an Officer's
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent with respect to such Defeasance or Covenant Defeasance have been
     complied with.

          (10) No default in the payment of the principal of and any premium and
     interest on any Senior Indebtedness beyond any applicable grace period
     shall have occurred and be continuing.

          (11) No other default with respect to any Senior Indebtedness shall
     have occurred and be continuing and shall have resulted in the acceleration
     of such Senior Indebtedness.

     SECTION 1305.  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST; MISCELLANEOUS PROVISIONS.

     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

     SECTION 1306.  REINSTATEMENT.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

                                ARTICLE FOURTEEN

                           CONVERSION OF SECURITIES

     SECTION 1401.  APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to the Securities of any
series which are convertible into shares of Common Stock of the Company, and the
issuance of such shares of Common Stock upon the conversion of Securities of
such series, except as otherwise specified as contemplated by Section 301 for
the Securities of such series.  The terms and provisions applicable to the
conversion of Securities of any series into securities of the Company (other
than Common Stock) shall, if applicable, be set forth in an Officers'
Certificate or established in one or more indentures supplemental hereto, prior
to the issuance of Securities of such series in accordance with Section 301.

     SECTION 1402.  EXERCISE OF CONVERSION PRIVILEGE

     In order to exercise a conversion privilege, the Holder of a Security of
any series with such a privilege shall surrender such Security to the Company at
the office or agency maintained for that purpose pursuant to Section 1002,
accompanied by written notice to the Company that the Holder elects to convert
such Security or a specified portion thereof.  Such notice shall also state, if
different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock
which shall be issuable on such conversion shall be issued.  Securities of such
series surrendered for conversion shall (if so required by the Company or the
Trustee) be duly endorsed by or accompanied by instruments of transfer in forms
satisfactory to the Company and the Trustee duly executed by the Holder or its
attorney duly authorized in writing; and, if expressly specified, as
contemplated by Section 301, to be applicable to any series of Securities,
Securities of such series so surrendered for conversion during the period from
the close of business on any Regular Record Date to the opening of business on
the next succeeding Interest Payment Date (excluding Securities or portions
thereof called for redemption during such period) shall also be accompanied by
payment in funds acceptable to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of such Security
then being converted, and such interest shall be payable to such Holder
notwithstanding the conversion of such Security, subject to the provisions of
Section 307 relating to the payment of Defaulted Interest by the Company.  As
promptly as practicable after the receipt of such notice and of any payment
required pursuant to a Board Resolution and, subject to Section 301, set forth,
or determined in the manner provided, in an Officers' Certificate, or
established in one or more indentures supplemental hereto setting forth the
terms of the Securities and the surrender of such Securities in accordance with
such reasonable regulations as the Company may prescribe, the Company shall
issue and shall deliver, at the office or agency at which such Security is
surrendered, to such Holder or on its written order, a certificate or
certificates for the number of full shares of Common Stock issuable upon the
conversion of such Security (or specified portion thereof), in accordance with
the provisions of such Board Resolution, Officers' Certificate or supplemental
indenture, and cash as provided therein in respect of any fractional share of
such Common Stock otherwise issuable upon such conversion.  Such conversion
shall be deemed to have been effected immediately prior to the close of business
on the date on which such notice and such payment, if required, shall have been
received in proper order for conversion by the Company and such Security shall
have been surrendered as aforesaid (unless such Holder 

                                      -57-
<PAGE>
 
shall have so surrendered such Security and shall have instructed the Company to
effect the conversion on a particular date following such surrender and such
Holder shall be entitled to convert such Security on such date, in which case
such conversion shall be deemed to be effected immediately prior to the close of
business on such date) and at such time the rights of the Holder of such
Security as such Security Holder shall cease and the person or persons in whose
name or names any certificate or certificates for shares of Common Stock of the
Company shall be issuable upon such conversion shall be deemed to have become
the holder or holders of record of the shares represented thereby. Except as set
forth above and subject to the final paragraph of Section 3.7, no payment or
adjustment shall be made upon any conversion on account of any interest accrued
on the Securities of such series surrendered for conversion or on account of any
dividends on the Common Stock of the Company issued upon such conversion.

     In the case of any Security of any series which is converted in part only,
upon such conversion the Company shall execute and the Trustee shall
authenticate and make available for delivery to or on the order of the Holder
thereof, at the expense of the Company, a new Security or Securities of such
series, of authorized denominations, in aggregate principal amount equal to the
unconverted portion of such Security.

     SECTION 1403.  NO FRACTIONAL SHARES. 

     No fractional share of Common Stock of the Company shall be issued upon
conversions of securities of any series. If more than one security of such
series shall be surrendered for conversion at one time by the same Holder, the
number of full shares which shall be issuable upon conversion shall be computed
on the basis of the aggregate principal amount of the securities of such series
(or specified portions thereof to the extent permitted hereby) so surrendered.
If, except for the provisions of this Section 1403, any Holder of a Security or
Securities of such series would be entitled to a fractional share of Common
Stock of the Company upon the conversion of such Security or Securities, or
specified portions thereof, the Company shall pay to such Holder an amount in
cash equal to the current market value of such fractional share computed, (1) if
such Common Stock is listed or admitted to unlisted trading privileges on a
National securities exchange, on the basis of the last reported sale price
regular way on such exchange on the last trading day prior to the date of
conversion upon which such a sale shall have been effected, or (2) if such
Common Stock is not at the time so listed or admitted to unlisted trading
privileges on a national securities exchange, on the basis of the average of the
bid and asked prices of such Common Stock in the over-the-counter market, on the
last trading day prior to the date of conversion, as reported by the National
Quotation Bureau, incorporated or similar organization if the National Quotation
Bureau, Incorporated is no longer reporting such information, or if not so
available, the fair market price as determined by the Board of Directors. For
purposes of this Section, "trading day" shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday other than any day on which the Common Stock is
not traded on the New York Stock Exchange, or if the Common Stock is not traded
on the New York Stock Exchange, on the principal exchange or market on which the
Common Stock is traded or quoted.

     SECTION 1404.  ADJUSTMENT OF CONVERSION PRICE

     The conversion price of Securities of any series that is convertible into
Common Stock of the Company shall be adjusted for any stock dividends, stock
splits, reclassification, combinations or similar transactions in accordance
with the terms of the supple-

                                      -58-
<PAGE>
 
mental indenture or Board Resolutions setting forth the terms of the Securities
of such series.

     Whenever the conversion price is adjusted, the Company shall compute the
adjusted conversion price in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted conversion price and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall forthwith
be filed at each office or agency maintained for the purpose of conversion of
Securities of such series pursuant to Section 1002 and, if different, with the
Trustee.  The Company shall forthwith cause a notice setting forth the adjusted
conversion price to be mailed, first class postage prepaid, to each Holder of
Securities of such series at its address appearing on the Security Register and
to any conversion agent other than the Trustee.

     SECTION 1405.  NOTICE OF CERTAIN CORPORATE ACTIONS

     In case:

          (1)  the Company shall declare a dividend (or any other distribution)
     on its Common Stock payable otherwise than in cash out of its retained
     earnings (other than a dividend for which approval of any shareholders of
     the Company is required); or

          (2)  the Company shall authorize the granting to the holders of its
     Common Stock of rights, options or warrants to subscribe for or purchase
     any shares of capital stock of any class or of any other rights (other than
     any such grant for which approval of any shareholders of the Company is
     required); or

          (3)  of any reclassification of the Common Stock of the Company (other
     than a subdivision or combination of its outstanding shares of Common
     Stock) or of any consolidation, merger or share exchange to which the
     Company is a party and for which approval of any shareholders of the
     Company is required, or of the sale of all or substantially all of the
     assets of the Company; or

          (4)  of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company;

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their last addresses as they shall appear in the
Security Register, at least 20 days (or 10 days in any case specified in clause
(1) or (2) above) prior to the applicable record date hereinafter specified, a
notice stating (A) the date on which a record is to be taken for the purpose of
such dividend, distribution, rights, options or warrants, or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined, or (B) the date on which such reclassification, consolidation,
merger, share exchange, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, dissolution,
liquidation or winding up.  If at any time the Trustee shall not be the
conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

                                      -59-

     SECTION 1406.  RESERVATION OF SHARES OF COMMON STOCK.

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock or treasury
shares, for the purpose of effecting the conversion of Securities, the full
number of shares of Common Stock of the Company then issuable upon the
conversion of all outstanding Securities of any series that has conversion
rights.

     SECTION 1407.  PAYMENT OF CERTAIN TAXES UPON CONVERSION.

     The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of its Common Stock on conversion of Securities
pursuant hereto.  The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of its Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the person requesting such issue has paid to the
Company the amount of any such tax, or has established, to the satisfaction of
the Company, that such tax has been paid.

     SECTION 1408.  NONASSESSABILITY. 

     The Company covenants that all shares of Common Stock which may be issued
upon conversion of securities will upon issue in accordance with the terms
hereof be duly and validly issued and fully paid and nonassessable.

     SECTION 1409.  EFFECT OF CONSOLIDATION OR MERGER ON CONVERSION PRIVILEGE

Unless otherwise provided as contemplated by Section 301 with respect to
Securities of any series, in case of any consolidation of the Company with, or
merger of the Company into or with any other Person, or in case of any sale of
all or substantially all of the assets of the Company, the Company or the Person
formed by such consolidation or the Person into which the Company shall have
been merged or the Person which shall have acquired such assets, as the case may
be, shall execute and deliver to the Trustee a supplemental indenture providing
that the Holder of each Security then outstanding of any series that is
convertible into Common Stock shall have the right, which right shall be the
exclusive conversion right thereafter available to said Holder (until the
expiration of the conversion right of such Security), to convert such Security
into the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such consolidation, merger or sale by a holder
of the number of shares of Common Stock into which such Security might have been
converted immediately prior to such consolidation, merger or sale, subject to
compliance with the other provisions of this Indenture, such Security and such
supplemental indenture.  Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in such Security.  The above provisions of this Section
shall similarly apply to successive consolidations, mergers or sales.  Unless
otherwise provided as contemplated by Section 301 with respect to Securities of
any series, it is expressly agreed and understood that anything in this
Indenture to the contrary notwithstanding, if, pursuant to such merger,
consolidation or sale, holders of outstanding shares of Common Stock do not
receive shares of common stock of the surviving corporation but receive other
securities, cash or other property or any combination thereof, Holders of
Securities shall not have the right to 

                                      -60-
<PAGE>
 
thereafter convert their Securities into common stock of the surviving
corporation or the corporation which shall have acquired such assets, but
rather, shall have the right upon such conversion to receive the other
securities, cash or other property receivable by a holder of the number of
shares of Common Stock into which the Securities held by such Holder might have
been converted immediately prior to such consolidation, merger or sale, all as
more fully provided in the first sentence of this Section 1409. Anything in this
Section 1409 to the contrary notwithstanding, the provisions of this Section
1409 shall not apply to a merger or consolidation of another corporation with or
into the Company pursuant to which both of the following conditions are
applicable: (1) the Company is the surviving corporation and (2) the outstanding
shares of Common Stock are not changed or converted into any other securities or
property (including cash) or changed in number or character or reclassified
pursuant to the terms of such merger or consolidation.

     As evidence of the kind and amount of shares of stock or other securities
or property (including cash) into which Securities may properly be convertible
after any such consolidation, merger or sale, or as to the appropriate
adjustments of the conversion prices applicable with respect thereto, the
Trustee shall be furnished with and may accept the certificate or opinion of an
independent certified public accountant with respect thereto; and, in the
absence of bad faith on the part of the Trustee, the Trustee may conclusively
rely thereon, and shall not be responsible or accountable to any Holder of
Securities for any provision in conformity therewith or approved by such
independent certified public accountant which may be contained in said
supplemental indenture.

     SECTION 1410.  DUTIES OF TRUSTEE REGARDING CONVERSION.

     Neither the Trustee nor any conversion agent shall at any time be under any
duty or responsibility to any Holder of Securities of any series that is
convertible into Common Stock to determine whether any facts exist which may
require any adjustment of the conversion price, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed,
whether herein or in any supplemental indenture (or whether a supplemental
indenture need be entered into), any resolutions of the Board of Directors or
written instrument executed by one or more officers of the Company provided to
be employed in making the same.  Neither the Trustee nor any conversion agent
shall be accountable with respect to the validity or value (or the kind or
amount) of any shares of Common Stock, or of any securities or property, which
may at any time be issued or delivered upon the conversion of any Securities and
neither the Trustee nor any conversion agent makes any representation with
respect thereto.  Neither the Trustee nor any conversion agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of Common Stock or stock certificates or other securities or property
upon the surrender of any Security for the purpose of conversion or to comply
with any of the covenants of the Company contained in this Article Fourteen or
in the applicable supplemental indenture, resolutions of the Board of Directors
or written instrument executed by one or more duly authorized officers of the
Company.  All Securities delivered for conversion shall be delivered to the
Trustee to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 309.

     SECTION 1411.  REPAYMENT OF CERTAIN FUNDS UPON CONVERSION.

     Any funds which at any time shall have been deposited by the Company or on
its behalf with the Trustee or any other paying agent for the purpose of paying
the principal of, and premium, if any, and interest, if any, on any of the
Securities (including funds 

                                      -61-
<PAGE>
 
deposited for the sinking fund referred to in Article Three hereof) and which
shall not be required for such purposes because of the conversion of such
Securities as provided in this Article Fourteen shall after such conversion be
repaid to the Company by the Trustee upon the Company's written request.

                                ARTICLE FIFTEEN

                          SUBORDINATION OF SECURITIES

     SECTION 1501.  SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS.

     The Company covenants and agrees, and each Holder, by the Holder's
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the indebtedness represented
by the Security and the payment of the principal of and premium and interest on
each and all of the Securities are hereby expressly made subordinate and junior
in right of payment to the prior payment in full of all Senior Indebtedness of
the Company, whether outstanding at the date of this Indenture or thereafter
incurred.  No provision of this Article shall prevent the occurrence of any
default or Event of Default hereunder.

     SECTION 1502.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

     Upon any payment by the Company or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the
Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Senior Indebtedness
of the Company shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any payment is made by the Company on
account of the principal or of any premium or interest on the Securities; and
upon any such dissolution or winding-up or liquidation or reorganization, any
payment by the Company, or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to which the Holders of the
Securities or the Trustee would be entitled to receive from the Company, except
for the provisions of this Article, shall be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Holders of the Securities or by
the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Indebtedness of the Company (pro rata to such holders on the
basis of the respective amounts of Senior Indebtedness held by such holders, as
calculated by the Company) or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay such Senior Indebtedness in
full, in money or money's worth, after giving effect to any concurrent payment
or distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the Holders of the Securities or to the
Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee before all Senior Indebtedness of the Company is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for 

                                      -62-
<PAGE>
 
the benefit of and shall be paid over or delivered to the holders of such Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, and their respective interests may
appear, as calculated by the Company, for application to the payment of all
Senior Indebtedness of the Company, as the case may be, remaining unpaid to the
extent necessary to pay such Senior Indebtedness in full in money in accordance
with its terms, after giving effect to any concurrent payment or distribution to
or for the benefit of the holders of such Senior Indebtedness.

     For purposes of this Article only, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which are subordinated in right of
payment to all Senior Indebtedness which may at the time be outstanding to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article.  The consolidation of the
Company with, or the merger of the Company into, another Person or the
liquidation or dissolution of the Company following the conveyance or transfer
of its properties and assets substantially as an entirety to another Person upon
the terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding-up, liquidation, reorganization, assignment for the benefit
of creditors or marshaling of assets and liabilities of the Company for the
purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or the Person which acquires by conveyance or
transfer such properties and assets substantially as an entirety, as the case
may be, shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article Eight.

     SECTION 1503.  PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION OF
SECURITIES.

     In the event that any Securities are declared due and payable before their
Stated Maturity, then and in such event the holders of Senior Indebtedness shall
be entitled to receive payment in full of all amounts due or to become due on or
in respect of all Senior Indebtedness or provision shall be made for such
payment in cash, before the Holders of the Securities are entitled to receive
any payment (including any payment which may be payable by reason of the payment
of any other indebtedness of the Company being subordinated to the payment of
the Securities) by the Company on account of the principal of or any premium or
interest on the Securities or on account of the purchase or other acquisition of
Securities; provided, however, that nothing in this Section shall prevent the
satisfaction of any sinking fund payment in accordance with Article Twelve by
delivering and crediting pursuant to Section 1202 Securities which have been
acquired (upon redemption or otherwise) prior to such declaration of
acceleration or which have been converted pursuant to Article Fourteen.

     In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

     The provisions of this Section shall not apply to any payment with respect
to which Section 1402 would be applicable.

                                      -63-
<PAGE>
 
     SECTION 1504.  NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

     In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness of the Company, as the case may be, beyond any applicable
grace period with respect thereto, or in the event that the maturity of any
Senior Indebtedness of the Company, as the case may be, has been accelerated
because of a default, or in the event that any other event has occurred and is
continuing on the basis of which the holders of any Senior Indebtedness may
accelerate the maturity thereof or demand payment in full, then, in any such
case, no payment shall be made by the Company with respect to the principal
(including redemption and sinking fund payments) of, or premium, if any, or
interest on the Securities until such default is cured or waived or ceases to
exist or any such acceleration or demand for payment has been rescinded.

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 1504, such payment shall be [paid over or delivered to
the Company] [held in trust for the benefit of, and shall be paid over or
delivered to, the holders of Senior Indebtedness or their respective
representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Indebtedness may have been issued, as their respective
interests may appear, but only to the extent that the holders of the Senior
Indebtedness (or their representative or representatives or a trustee) notify
the Trustee in writing within 90 days of such payment of the amounts then due
and owing on the Senior Indebtedness and only the amounts specified in such
notice to the Trustee shall be paid to the holders of Senior Indebtedness].

     SECTION 1505.  PAYMENT PERMITTED IN CERTAIN SITUATIONS.

     Nothing contained in this Article or elsewhere in this Indenture or in any
of the Securities shall prevent (1) the Company, at any time except during the
pendency of any dissolution, winding-up, liquidation or reorganization of the
Company, whether voluntary or involuntary or any bankruptcy, insolvency,
receivership or other proceedings of the Company referred to in Section 1502 or
under the conditions described in Section 1503 or 1504, from making payments at
any time of principal of, or premium, if any, or interest on the Securities, or
(2) the application by the Trustee of any money deposited with it hereunder to
the payment of or on account of the principal of, or premium, if any, or
interest on the Securities or the retention of such payment by the Holders, if,
at the time of such application by the Trustee, it did not have actual knowledge
that such payment would have been prohibited by the provisions of this Article.

     SECTION 1506.  SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

     Subject to the payment in full of all Senior Indebtedness or the provision
for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Indebtedness, the rights of the Holders of
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Indebtedness pursuant to the provisions of
this Article (equally and ratably with the holders of indebtedness of the
Company which by its express terms is subordinated to indebtedness of the
Company to substantially the same extent as the Securities are subordinated to
the Senior Indebtedness and is entitled to like rights of subrogation) to the
rights of the holders of 

                                      -64-
<PAGE>
 
such Senior Indebtedness to receive payments and distributions of cash, property
and securities applicable to the Senior Indebtedness until the principal of and
any premium and interest on the Securities shall be paid in full. For purposes
of such subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the Holders of
Securities or the Trustee would be entitled except for the provisions of this
Article, and no payments over pursuant to the provisions of this Article to or
for the benefit of the holders of Senior Indebtedness by Holders of Securities
or the Trustee, shall, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

     SECTION 1507.  PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

     The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of Securities on the one hand and
the holders of Senior Indebtedness on the other hand.  Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (1) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article of the holders of Senior Indebtedness, is intended to rank
equally with all other general obligations of the Company), to pay to the
Holders of Securities the principal of and any premium and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (2) affect the relative rights against the Company of the
Holders of Securities and creditors of the Company, as the case may be, other
than the holders of Senior Indebtedness; or (3) prevent the Trustee or the
Holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article of the holders of Senior Indebtedness to receive cash,
property and securities otherwise payable or deliverable to the Trustee or such
Holder.

     [SECTION 1508.  TRUSTEE TO EFFECTUATE SUBORDINATION.

     Each Holder of a Security by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article and appoints the Trustee such Holder's attorney-in-fact for any and all
such purposes.]

     SECTION 1509.  NO WAIVER OF SUBORDINATION PROVISIONS

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

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Trustee or the Holders of Securities, without
incurring responsibility to the Holders of Securities and without impairing or
releasing the subordination provided in this Article or the obligations
hereunder of the Holders of Securities to the holders of Senior 

                                      -65-
<PAGE>
 
Indebtedness do any one or more of the following: (1) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness or otherwise amend or supplement in any manner Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (2) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (3)
release any Person liable in any manner for the collection of Senior
Indebtedness; and (4) exercise or refrain from exercising any rights against the
Company and any other Person.

     SECTION 1510.  NOTICE TO TRUSTEE. 

     The Company shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Company which would prohibit the making of
any payment to or by the Trustee in respect of any Securities pursuant to the
provisions of this Article. Notwithstanding the provisions of this Article or
any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment to or by the Trustee in respect of any Securities pursuant to the
provisions of this Article, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a holder
or holders of Senior Indebtedness or from any trustee therefor; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 602, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall have not received the notice
provided for in this Section at least two business days prior to the date upon
which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of or any premium
or interest on any Securities), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
money and to apply the same to the purposes for which they were received, and
shall not be affected by any notice to the contrary that may be received by it
within two Business Days prior to such date.

     Subject to the provisions of Section 602, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Indebtedness (or a trustee therefor) to establish that
such notice has been given by a holder of Senior Indebtedness (or a trustee
therefor).  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, 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, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

     SECTION 1511.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT.

     Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 603, and the
Holders of Securities shall be entitled to conclusively 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 

                                      -66-
<PAGE>
 
certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, 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, as the case may be, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article.

     SECTION 1512.  TRUSTEE NOT FIDUCIARY FOR 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, and no implied covenants or obligations
with respect to the holders of such Senior Indebtedness shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness and shall not be liable to
any such holders or creditors if it shall in good faith pay over or distribute
to Holders of Securities or to the Company or to any other Person cash, property
or securities to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article or otherwise.

     SECTION 1513.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS,
PRESERVATION OF TRUSTEE'S RIGHTS.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness which may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

     Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

     SECTION 1514.  ARTICLE APPLICABLE TO PAYING AGENTS.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided, however, that
Section 1413 shall not apply to the Company or any Affiliate of the Company if
it or such Affiliate acts as Paying Agent.

     SECTION 1515.  CERTAIN CONVERSIONS DEEMED PAYMENT.

     For the purposes of this Article only, (1) the issuance and delivery of
junior securities (or cash paid in lieu of fractional shares) upon conversion of
Securities in accordance with Article Fourteen, or pursuant to the terms set
forth in an Officers' Certificate or established in one or more indentures
supplemental hereto in accordance with Section 301, shall not be deemed to
constitute a payment or distribution on account of the principal of or premium
or interest on Securities or on account of the purchase or other acquisition of
Securities, and (2) the payment, issuance or delivery of cash, property or
securities (other than junior securities and cash paid in lieu of fractional
shares) upon 

                                      -67-
<PAGE>
 
conversion of a Security shall be deemed to constitute payment on account of the
principal of such Security. For the purposes of this Section, the term "junior
securities" means (A) shares of any stock of any class of the Company and (B)
securities of the Company which are subordinated in right of payment to all
Senior Indebtedness which may be outstanding at the time of issuance or delivery
of such securities to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of Securities, the right, which
is absolute and unconditional, of the Holder of any Security to convert such
Security in accordance with Article Fourteen.

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

     IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.

Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

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

          (ii) requires the consent or vote of greater than a majority in
     principal amount of the holders of the Debentures (a "Super Majority") to

     The foregoing provisions of this Section 2.06(a) shall be in lieu of

Indenture Act is hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. Upon such waiver, any such
default shall cease to exist, and any Event of Default with respect to the Trust

subsequent or other default or an Event of Default with respect to the Trust
Preferred Securities or impair any right consequent thereon. Any waiver by the

Default under the Indenture:

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

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

provided further, each Holder of Common Securities will be deemed to have waived
any such Event of Default and all Events of Default with respect to the Common
Securities and its consequences until all Events of Default with respect to the
Trust Preferred Securities have been cured, waived or otherwise eliminated, and
until such Events of Default have been so cured, waived or otherwise eliminated,
the Institutional Trustee will be deemed to be acting solely on behalf of the
Holders of the Trust Preferred Securities and only the Holders of the Trust
Preferred Securities will have the right to direct the Institutional Trustee in
accordance with the terms of the Securities.  The foregoing provisions of this
Section 2.06(b) shall be in lieu of Section 316(a)(1)(A) and 316(a)(1)(B) of the
Trust Indenture Act and such Section 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. Subject to the foregoing
provisions of this Section 2.06(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

     (c)  A waiver of an Event of Default under the Indenture by the
Institutional Trustee at the direction of the Holders of the Trust Preferred
Securities, constitutes a waiver of the corresponding Event of Default under
this Declaration. The foregoing 

                                       9
<PAGE>
 
provisions of this Section 2.06(c) shall be in lieu of Section 316(a)(1)(B) of
the Trust Indenture Act and such Section 316(a)(1)(B) of the Trust Indenture Act
is hereby expressly excluded from this Declaration and the Securities, as
permitted by the Trust Indenture Act.

     Section 2.07.  EVENT OF DEFAULT; NOTICE.

     (a)  The Institutional Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders of the Securities, notices of all defaults with respect to the
Securities actually known to a Responsible Officer of the Institutional Trustee,
unless such defaults have been cured before the giving of such notice (the term
"defaults" for the purposes of this Section 2.07(a) being hereby defined to be
an Event of Default as defined in the Indenture, not including any periods of
grace provided for therein and irrespective of the giving of any notice provided
therein); provided that, except for a default in the payment of principal of (or
premium, if any) or interest on any of the Debentures or in the payment of any
sinking fund installment established for the Debentures, the Institutional
Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer of the Institutional Trustee in good faith determines that
the withholding of such notice is in the interests of the Holders of the
Securities.

     (b)  The Institutional Trustee shall not be deemed to have knowledge of any
default except:
 
          (i)  a default under Sections 501(1), 501(2) and 501(3) of the
     Indenture; or

               (ii) causing the Trust to be classified for United States federal
          income tax purposes as a grantor trust; and

               (iii)  cooperating with the Sponsor to ensure that the Debentures
          will be treated as indebtedness of the Sponsor for United States
          federal income tax purposes,

          provided that such action does not adversely affect the interests of
     Holders; and

          (q)  to take all action necessary to cause all applicable tax returns
     and tax information reports that are required to be filed with respect to
     the Trust to be duly prepared and filed by the Regular Trustees, on behalf
     of the Trust.

     The Regular Trustees must exercise the powers set forth in this Section
3.06 in a manner that is consistent with the purposes and functions of the Trust
set out in Section 3.03, and the Regular Trustees shall not take any action that
is inconsistent with the purposes and functions of the Trust set forth in
Section 3.03.

                                       13

     Subject to this Section 3.06, the Regular Trustees shall have none of the
powers or the authority of the Institutional Trustee set forth in Section 3.08.

     Any expenses incurred by the Regular Trustees pursuant to this Section 3.06
shall be reimbursed by the Sponsor.

     Section 3.07.  PROHIBITION OF ACTIONS BY THE TRUST AND THE TRUSTEES.

     (a)  The Trust shall not, and the Trustees (including the Institutional
Trustee) shall cause the Trust not to, engage in any activity other than as
required or authorized by this Declaration. In particular, the Trust shall not
and the Trustees (including the Institutional Trustee) shall cause the Trust not
to:

          (i)  invest any proceeds received by the Trust from holding the
     Debentures, but shall distribute all such proceeds to Holders of
     Securities pursuant to the terms of this Declaration and of the Securities;

          (ii) acquire any assets other than as expressly provided herein;

          (iii)  possess Trust property for other than a Trust purpose;

          (iv) make any loans or incur any indebtedness other than loans
     represented by the Debentures;

          (v) possess any power or otherwise act in such a way as to vary the
     Trust assets or the terms of the Securities in any way whatsoever;

          (vi) issue any securities or other evidences of beneficial ownership
     of, or beneficial interest in, the Trust other than the Securities; or

          (vii)  other than as provided in this Declaration or Annex I, (A)
     direct the time, method and place of exercising any trust or power
     conferred upon the Debenture Trustee with respect to the Debentures, (B)
     waive any past default that is waivable under the Indenture, (C) exercise
     any right to rescind or annul any declaration that the principal of all the
     Debentures shall be due and payable, or (D) consent to any amendment,
     modification or termination of the Indenture or the Debentures where such
     consent shall be required unless the Trust shall have received an opinion
     of counsel to the effect that such modification will not cause more than an
     insubstantial risk that for United States federal income tax purposes the
     Trust will not be classified as a grantor trust.

     Section 3.08.LEGAL TITLE TO THE DEBENTURES.

     (a) The legal title to the Debentures shall be owned by and held of record
in the name of the Institutional Trustee in trust for the benefit of the Holders
of the Securities. The right, title and interest of the Institutional Trustee to
the Debentures shall vest automatically in each Person who may hereafter be
appointed as Institutional Trustee in accordance with Section 5.07. Such vesting
and cessation of title shall be effective whether or not conveyancing documents
with regard to the Debentures have been executed and delivered.

                                       14
<PAGE>
 
     (b) The Institutional Trustee shall not transfer its right, title and
interest in the Debentures to the Regular Trustees or to the Delaware Trustee
(if the Institutional Trustee does not also act as Delaware Trustee).

     (c) The Institutional Trustee shall:

          (i) establish and maintain a segregated non-interest bearing trust
     account (the "Institutional Trustee Account") in the name of and under the
     exclusive control of the Institutional Trustee on behalf of the Holders of
     the Securities and, upon the receipt of payments of funds made in respect
     of the Debentures held by the Institutional Trustee, deposit such funds
     into the Institutional Trustee Account and make payments to the Holders of
     the Trust Preferred Securities and Holders of the Common Securities from
     the Institutional Trustee Account in accordance with Section 6.01. Funds in
     the Institutional Trustee Account shall be held uninvested until disbursed
     in accordance with this Declaration. The Institutional Trustee Account
     shall be an account that is maintained with a banking institution (which
     may be with the Institutional Trustee) the rating on whose long-term
     unsecured indebtedness is at least equal to the rating assigned to the
     Trust Preferred Securities by a "nationally recognized statistical rating
     organization", as that term is defined for purposes of Rule 436(g)(2) under
     the Securities Act;

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

          (iii)  upon written notice of Distribution issued by the Regular
     Trustees in accordance with the terms of the Securities, engage in such
     ministerial activities as shall be necessary or appropriate to effect the
     Distribution of the Debentures to Holders of Securities upon the occurrence
     of certain special events (as may be defined in the terms of the
     Securities) arising from a change in law or a change in legal
     interpretation or other specified circumstances pursuant to the terms of
     the Securities.

     (d) The Institutional Trustee shall take all actions and perform such
duties as may be specifically required of the Institutional Trustee pursuant to
the terms of the Securities.

     (e) The Institutional Trustee shall take any Legal Action which arises out
of or in connection with an Event of Default of which a Responsible Officer of
the Institutional Trustee has actual knowledge or the Institutional Trustee's
duties and obligations under this Declaration or the Trust Indenture Act;
provided, however, that the holders of a majority in liquidation amount of the
Trust Preferred Securities will have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Institutional
Trustee or to direct the exercise of any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee to exercise the remedies available to it as a Holder of
the Debentures. If the Institutional Trustee fails to enforce its rights under
the Debentures, a holder of Trust Preferred Securities, to the extent permitted
by law, may institute a legal proceeding directly against Nuevo to enforce the
Institutional Trustee's rights under the Debentures without first instituting
any legal proceeding against the Institutional Trustee or any other 

                                       15
<PAGE>
 
Person; provided further, that, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Sponsor to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
then a Holder of Trust Preferred Securities may directly institute a proceeding
for enforcement of payment to such Holder of the principal of or interest on the
Debentures having a principal amount equal to the aggregate liquidation amount
of the Trust Preferred Securities of such Holder (a "Direct Action") on or after
the respective due date specified in the Debentures. In connection with such
Direct Action, the rights of the Holders of the Common Securities will be
subrogated to the rights of such Holder of Trust Preferred Securities to the
extent of any payment made by the Sponsor to such Holder of Trust Preferred
Securities in such Direct Action. Except as provided in the preceding sentences,
the Holders of Trust Preferred Securities shall have no right or power to
exercise directly any other remedy available to the holders of the Debentures.

     (f) The Institutional Trustee shall continue to serve as a Trustee until
either:

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

          (ii) a Successor Institutional Trustee has been appointed and has
     accepted that appointment in accordance with Section 5.07.

     (g) The Institutional Trustee shall have the legal power to exercise all of
the rights, powers and privileges of a holder of Debentures under the Indenture
and, if an Event of Default actually known to a Responsible Officer of the
Institutional Trustee occurs and is continuing, the Institutional Trustee shall,
for the benefit of Holders of the Securities, enforce its rights as holder of
the Debentures subject to the rights of the Holders pursuant to the terms of
such Securities.

     (h) The Institutional Trustee may authorize one or more Persons (each, a
"Paying Agent") to pay Distributions, redemption payments or liquidation
payments on behalf of the Trust with respect to all Securities and any such
Paying Agent shall comply with Section 317(b) of the Trust Indenture Act. Any
Paying Agent may be removed by the Institutional Trustee at any time and a
successor Paying Agent or additional Paying Agents may be appointed at any time
by the Institutional Trustee.

     (i) Subject to this Section 3.07, the Institutional Trustee shall have none
of the duties, liabilities, powers or the authority of the Regular Trustees set
forth in Section 3.06.

     The Institutional Trustee must exercise the powers set forth in this
Section 3.07 in a manner that is consistent with the purposes and functions of
the Trust set out in Section 3.03, and the Institutional Trustee shall not take
any action that is inconsistent with the purposes and functions of the Trust set
out in Section 3.03.

     Section 3.09.  CERTAIN DUTIES AND RESPONSIBILITIES OF THE INSTITUTIONAL
TRUSTEE.

     (a) The Institutional Trustee, before the occurrence of any Event of
Default and after the curing or waiving of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Declaration and 

                                       16
<PAGE>
 
no implied covenants or obligations shall be read into this Declaration against
the Institutional Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.06(c)) of which a Responsible
Officer of the Institutional Trustee has actual knowledge, the Institutional
Trustee shall exercise such of the rights and powers vested in it by this
Declaration, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

     (b) No provision of this Declaration shall be construed to relieve the
Institutional Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

          (i) prior to the occurrence of an Event of Default and after the
     curing or waiving of all such Events of Default that may have occurred:

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

               (B) in the absence of bad faith on the part of the Institutional
          Trustee, the Institutional Trustee may conclusively rely, as to the
          truth of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the
          Institutional Trustee and conforming to the requirements of this
          Declaration; but in the case of any such certificates or opinions that
          by any provision hereof are specifically required to be furnished to
          the Institutional Trustee, the Institutional Trustee shall be under a
          duty to examine the same to determine whether or not they conform to
          the requirements of this Declaration;

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

          (iii)  the Institutional Trustee shall not be liable with respect to
     any action taken or omitted to be taken by it in good faith in accordance
     with the direction of the Holders of not less than a Majority in
     liquidation amount of the Securities relating to the time, method and place
     of conducting any proceeding for any remedy available to the Institutional
     Trustee, or exercising any trust or power conferred upon the Institutional
     Trustee under this Declaration;

          (iv) no provision of this Declaration shall require the Institutional
     Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers, if it shall have reasonable
     grounds for believing that the repayment of such funds or liability is not
     reasonably assured to it under the terms of this Declaration or indemnity
     reasonably satisfactory to the Institutional Trustee against such risk or
     liability is not reasonably assured to it;

                                       17
<PAGE>
 
          (v) the Institutional Trustee's sole duty with respect to the custody,
     safe keeping and physical preservation of the Debentures and the
     Institutional Trustee Account shall be to deal with such property in a
     similar manner as the Institutional Trustee deals with similar property for
     its own account, subject to the protections and limitations on liability
     afforded to the Institutional Trustee under this Declaration and the Trust
     Indenture Act;

          (vi) the Institutional Trustee shall have no duty or liability for or
     with respect to the value, genuineness, existence or sufficiency of the
     Debentures or the payment of any taxes or assessments levied thereon or in
     connection therewith;

          (vii)  the Institutional Trustee shall not be liable for any interest
     on any money received by it except as it may otherwise agree in writing
     with the Sponsor, and money held by the Institutional Trustee need not be
     segregated from other funds held by it except in relation to the
     Institutional Trustee Account maintained by the Institutional Trustee
     pursuant to Section 3.08(c)(i) and except to the extent otherwise required
     by law; and

          (viii)  the Institutional Trustee shall not be responsible for
     monitoring the compliance by the Regular Trustees or the Sponsor with their
     respective duties under this Declaration, nor shall the Institutional
     Trustee be liable for any default or misconduct of the Regular Trustees or
     the Sponsor.

     request, shall be promptly delivered by the Sponsor or the Regular
     Trustees;

          (iv) the Institutional Trustee shall have no duty to see to any

          (b) The Trust may, with the consent of the Regular Trustees or, if
     there are more than two, a majority of the Regular Trustees and without the
     consent of the Holders of the Securities, the Delaware Trustee or the
     Institutional Trustee, consolidate, amalgamate, merge with or into, or be
     replaced by a trust organized as such under the laws of any State; provided
     that:

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

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

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

          (ii) the Sponsor expressly acknowledges a trustee of the Successor
     Entity that possesses the same powers and duties as the Institutional
     Trustee as the Holder of the Debentures;

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

          (iv) such merger, consolidation, amalgamation or replacement does not
     cause the Trust Preferred Securities (including any Successor Securities)
     to be downgraded by any nationally recognized statistical rating
     organization;

          (v) such merger, consolidation, amalgamation or replacement does not
     adversely affect the rights, preferences and privileges of the Holders of
     the Securities (including any Successor Securities) in any material respect
     (other than with respect to any dilution of such Holders' interests in the
     Trust Preferred Securities as a result of such merger, consolidation,
     amalgamation or replacement);

          (vi) such Successor Entity has a purpose identical to that of the
     Trust;

          (vii)  prior to such merger, consolidation, amalgamation or
     replacement, the Sponsor has received an opinion of a nationally recognized
     independent counsel to the Trust experienced in such matters to the effect
     that:

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

                                       21
<PAGE>
 
               (B) following such merger, consolidation, amalgamation or
          replacement, neither the Trust nor the Successor Entity will be
          required to register as an Investment Company; and

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

          (viii)  the Sponsor guarantees the obligations of such Successor
     Entity under the Successor Securities at least to the extent provided by
     the Securities Guarantees.

     (c) Notwithstanding Section 3.15(b), the Trust shall not, except with the
consent of Holders of 100% in liquidation amount of the Securities, consolidate,
amalgamate, merge with or into, or be replaced by any other Person or permit any
other Person to consolidate, amalgamate, merge with or into, or replace it if
such consolidation, amalgamation, merger or replacement would cause the Trust or
Successor Entity to be classified as other than a grantor trust for United
States federal income tax purposes.

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

on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Regular Trustees may

     Any corporation or bank into which the Institutional Trustee or the
Delaware Trustee, as the case may be, may be merged or converted or with which
either may be consolidated, or any corporation or bank resulting from any
merger, conversion or consolidation to which the Institutional Trustee or the
Delaware Trustee, as the case may be, shall be a party, or any corporation or
bank succeeding to all or substantially all the corporate trust business of the
Institutional Trustee or the Delaware Trustee, as the case may be, shall be the
successor of the Institutional Trustee or the Delaware Trustee, as the case may
be, hereunder, provided such corporation or bank shall be otherwise qualified
and eligible under this Article, without the execution or filing of any paper or
any further act on the part of any of the parties hereto; provided, however,

     (a) The Regular Trustees shall on behalf of the Trust issue one class of
convertible preferred securities representing undivided beneficial interests in
the assets of the Trust having such terms as are set forth in Annex I (the
"Trust Preferred Securities") and one class of convertible common securities
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities"). The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Trust Preferred Securities and the Common Securities.

     (b) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

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

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

     Section 7.02.  EXECUTION AND AUTHENTICATION.

     (a) The Certificates shall be signed on behalf of the Trust by a Regular
Trustee. In case any Regular Trustee of the Trust who shall have signed any of
the Securities shall cease to be such Regular Trustee before the Certificates so
signed shall be delivered by the Trust, such Certificates nevertheless may be
delivered as though the person who signed such Certificates had not ceased to be
such Regular Trustee; and any Certificate may be signed on behalf of the Trust
by such persons who, at the actual date of execution of such 

                                       28
<PAGE>
 
Security, shall be the Regular Trustees of the Trust, although at the date of
the execution and delivery of the Declaration any such person was not such a
Regular Trustee.

     (b) One Regular Trustee shall sign the Trust Preferred Securities for the
Trust by manual or facsimile signature. Unless otherwise determined by the
Trust, such signature shall, in the case of Common Securities, be a manual
signature.

     A Trust Preferred Security shall not be valid until authenticated by the
manual signature of an authorized signatory of the Institutional Trustee. The
signature shall be conclusive evidence that the Trust Preferred Security has
been authenticated under this Declaration.

     Upon a written order of the Trust signed by one Regular Trustee, the
Institutional Trustee shall authenticate the Trust Preferred Securities for
original issue.

     The Institutional Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Trust Preferred Securities. An authenticating agent
may authenticate Trust Preferred Securities whenever the Institutional Trustee
may do so. Each reference in this Declaration to authentication by the
Institutional Trustee includes authentication by such agent. An authenticating
agent has the same rights as the Institutional Trustee to deal with the Company
or an Affiliate of the Company.

     Section 7.03.  FORM AND DATING.

     The Trust Preferred Securities and the Institutional Trustee's certificate
of authentication shall be substantially in the form of Exhibit A-1 and the
Common Securities shall be substantially in the form of Exhibit A-2, each of
which is hereby incorporated in and expressly made a part of this Declaration.
Certificates may be printed, lithographed or engraved or may be produced in any
other manner as is reasonably acceptable to the Regular Trustees, as evidenced
by their execution thereof. The Securities may have letters, numbers, notations
or other marks of identification or designation and such legends or endorsements
required by law, stock exchange rule, agreements to which the Trust is subject,
if any, or usage (provided that any such notation, legend or endorsement is in a
form acceptable to the Trust). The Trust at the direction of the Sponsor shall
furnish any such legend not contained in Exhibit A-1 to the Institutional
Trustee in writing. Each Trust Preferred Security Certificate shall be dated the
date of its authentication. The terms and provisions of the Securities set forth
in Annex I and the forms of Securities set forth in Exhibits A-1 and A-2 are
part of the terms of this Declaration and to the extent applicable, the

thereby.

form, the Trust shall maintain in the Borough of Manhattan, City of New York,
State of New York, an office or agency where the Trust Preferred Securities may
be presented for payment ("Paying Agent"). The Trust shall maintain an office or
agency where Securities may be presented for conversion ("Conversion Agent").
The Trust may appoint the Paying Agent and the Conversion Agent and may appoint
one or more additional paying agents and one or more additional conversion
agents in such other locations as it shall determine. The 

                                       29
<PAGE>
 
term "Paying Agent" includes any additional paying agent and the term
"Conversion Agent" includes any additional conversion agent. The Trust may
change any Paying Agent or Conversion Agent without prior notice to any Holder.
The Trust shall notify the Institutional Trustee in writing of the name and
address of any Agent not a party to this Declaration. If the Trust fails to
appoint or maintain another entity as Paying Agent or Conversion Agent, the
Institutional Trustee shall act as such. The Trust or any of its Affiliates may
act as Paying Agent or Conversion Agent. The Trust shall act as Paying Agent and
Conversion Agent for the Common Securities. The Paying Agent and Conversion
Agent shall be entitled to the rights and protections extended to the
Institutional Trustee when acting in such capacity.

     The Trust initially appoints the Institutional Trustee as Conversion Agent
for the Trust Preferred Securities, and the Trust initially appoints
________________ as Paying Agent for the Trust Preferred Securities.

     Debentures held by the Institutional Trustee shall have been distributed to
     the Holders of Securities in exchange for all of the Securities;

          (vi) upon the distribution of the Sponsor's common stock to all
     Securities Holders upon conversion of all outstanding Trust Preferred
     Securities;

Delaware.

     (c) The provisions of Sections 3.09 and 3.10 and Article 10 shall survive
the termination of the Trust.

                             TRANSFER OF INTERESTS


     Section 9.01.  TRANSFER OF SECURITIES.

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

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

     (c) Subject to this Article 9, the Sponsor and any Related Party may only
transfer Common Securities to the Sponsor or a Related Party of the Sponsor;
provided that, any such transfer is subject to the condition precedent that the
transferor obtain the written opinion of nationally recognized independent
counsel experienced in such matters that such transfer would not cause more than
an insubstantial risk that:

          (i) the Trust would not be classified for United States federal income
     tax purposes as a grantor trust; and

          (ii) the Trust would be an Investment Company required to register
     under the Investment Company Act or the transferee would become an
     Investment Company required to register under the Investment Company Act.

     Section 9.02.  TRANSFER OF CERTIFICATES.

     The Regular Trustees shall provide for the registration of Certificates and
of transfers of Certificates, which will be effected without charge but only
upon payment (with such indemnity as the Regular Trustees may require) in
respect of any tax or other government charges that may be imposed in relation
to it. Upon surrender for registration of transfer of any Certificate, the
Regular Trustees shall cause one or more new Certificates to be issued in the
name of the designated transferee or transferees. Every Certificate surrendered
for registration of transfer shall be accompanied by a written instrument of
transfer in form satisfactory to the Regular Trustees duly executed by the
Holder or such Holder's attorney duly authorized in writing. Each Certificate
surrendered 

                                       31
<PAGE>
 
for registration of transfer shall be canceled by the Regular Trustees. A
transferee of a Certificate shall be entitled to the rights and subject to the
obligations of a Holder hereunder upon the receipt by such transferee of a
Certificate. By acceptance of a Certificate, each transferee shall be deemed to
have agreed to be bound by this Declaration.

     Section 9.03.  DEEMED SECURITY HOLDERS.

     The Trustees may treat the Person in whose name any Certificate shall be
registered on the books and records of the Trust as the sole holder of such
Certificate and of the Securities represented by such Certificate for purposes
of receiving Distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities represented by such
Certificate on the part of any Person, whether or not the Trust shall have
actual or other notice thereof.

     Section 9.04.  BOOK ENTRY INTERESTS.

     Unless otherwise specified in the terms of the Trust Preferred Securities,
the Trust Preferred Securities Certificates, on original issuance, will be
issued in the form of one or more, fully registered, global Trust Preferred
Security Certificates (each a "Global Certificate"), to be delivered to DTC, the
initial Clearing Agency, by, or on behalf of, the Trust. Such Global
Certificates shall initially be registered on the books and records of the Trust
in the name of Cede & Co., the nominee of DTC, and no Trust Preferred Security
Beneficial Owner will receive a definitive Trust Preferred Security Certificate
representing such Trust Preferred Security Beneficial Owner's interests in such
Global Certificates, except as provided in Section 9.07. Unless and until

Trust Preferred Security Beneficial Owners pursuant to Section 9.07:

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

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

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

exercised only through the Clearing Agency and shall be limited to those
established by law and agreements between such Preferred Security Beneficial
Owners and the Clearing Agency and/or the Clearing Agency Participants,
including receiving and transmitting payments of Distributions on the Global
Certificates to such Clearing Agency Participants. DTC will make book entry
transfers among the Clearing Agency Participants; provided, that solely for the
purposes of determining whether the Holders of the requisite amount of Trust
Preferred Securities have voted on any matter provided for in this Declaration,
so long as Definitive Trust Preferred Security Certificates have not been
issued, the Trustees 

                                       32
<PAGE>
 
may conclusively rely on, and shall be protected in relying on, any written
instrument (including a proxy) delivered to the Trustees by the Clearing Agency
setting forth the Trust Preferred Security Beneficial Owners' votes or assigning
the right to vote on any matter to any other Persons either in whole or in part.

     Section 9.05.  NOTICES TO CLEARING AGENCY.

     Whenever a notice or other communication to the Trust Preferred Security
Holders is required under this Declaration, unless and until Definitive Trust
Preferred Security Certificates shall have been issued to the Trust Preferred
Security Beneficial Owners pursuant to Section 9.07, the Regular Trustees shall
give all such notices and communications specified herein to be given to the
Trust Preferred Security Holders to the Clearing Agency, and shall have no
notice obligations to the Trust Preferred Security Beneficial Owners.

     Section 9.06.  APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

     If any Clearing Agency elects to discontinue its services as securities
depositary with respect to the Trust Preferred Securities, the Regular Trustees
may, in their sole discretion, appoint a successor Clearing Agency with respect
to such Trust Preferred Securities.

     Section 9.07.  DEFINITIVE TRUST PREFERRED SECURITY CERTIFICATES.

     If:

     (a) a Clearing Agency elects to discontinue its services as securities
depositary with respect to the Trust Preferred Securities and a successor
Clearing Agency is not appointed within 90 days after such discontinuance
pursuant to Section 9.06; or

     (b) the Regular Trustees elect after consultation with the Sponsor to
terminate the book entry system through the Clearing Agency with respect to the
Trust Preferred Securities,

     then:

     (c) Definitive Trust Preferred Security Certificates shall be prepared by
the Regular Trustees on behalf of the Trust with respect to such Trust Preferred
Securities; and

     (d) upon surrender of the Global Certificates by the Clearing Agency,
accompanied by registration instructions, the Regular Trustees shall cause
Definitive Trust Preferred Security Certificates to be delivered to Trust
Preferred Security Beneficial Owners in accordance with the instructions of the
Clearing Agency. Neither the Trustees nor the Trust shall be liable for any
delay in delivery of such instructions and each of them may conclusively rely on
and shall be protected in relying on, said instructions of the Clearing Agency.
The Definitive Trust Preferred Security Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to 

                                       33
<PAGE>
 
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which Trust Preferred Securities
may be listed, or to conform to usage.

     Section 9.08.  MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

     If:

     (a) any mutilated Certificates should be surrendered to the Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and

     (b) there shall be delivered to the Institutional Trustee or the Regular
Trustees such security or indemnity as may be required by them to keep each of
them harmless, then, in the absence of notice that such Certificate shall have
been acquired by a bona fide purchaser, the Institutional Trustee or any Regular
Trustee on behalf of the Trust shall execute and deliver, in exchange for, or in
lieu of, any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like denomination. In connection with the issuance of any new
Certificate under this Section 9.08, the Institutional Trustee or the Regular
Trustees may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith. Any duplicate
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an ownership interest in the relevant Securities, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

     Section 10.01.  LIABILITY.

     (a) Except as expressly set forth in this Declaration, the Securities
Guarantees and the terms of the Securities, the Sponsor shall not be:

          (i) personally liable for the return of any portion of the capital
     contributions (or any return thereon) of the Holders of the Securities
     which shall be made solely from assets of the Trust; or

          (ii) be required to pay to the Trust or to any Holder of Securities
     any deficit upon dissolution of the Trust or otherwise.

     (b) The Holder of the Common Securities shall be liable for all of the
debts and obligations of the Trust (other than with respect to the Securities)
to the extent not satisfied out of the Trust's assets.

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

     Section 10.02.  EXCULPATION.

     (a) No Indemnified Person shall be liable, responsible or accountable in
damages or otherwise to the Trust or any Covered Person for any loss, damage or
claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith on behalf of the Trust and in a manner such
Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Declaration or by law, except that
an Indemnified Person shall be liable for any such loss, damage or claim
incurred by reason of such Indemnified Person's gross negligence or willful
misconduct with respect to such acts or omissions.

     (b) An Indemnified Person shall be fully protected in relying in good faith
upon the records of the Trust and upon such information, opinions, reports or
statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Trust, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits, losses, or any other facts
pertinent to the existence and amount of assets from which Distributions to
Holders of Securities might properly be paid.

     Section 10.03.  FIDUCIARY DUTY.

     (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration. The provisions of
this Declaration, to the extent that they restrict the duties and liabilities of
an Indemnified Person otherwise existing at law or in equity (other than the
duties imposed on the Institutional Trustee under the Trust Indenture Act), are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person.

     (b) Unless otherwise expressly provided herein:

          (i) whenever a conflict of interest exists or arises between any
     Covered Persons; or

          (ii) whenever this Declaration or any other agreement contemplated
     herein or therein provides that an Indemnified Person shall act in a manner
     that is, or provides terms that are, fair and reasonable to the Trust or
     any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

                                       35
<PAGE>
 
     (c) Whenever in this Declaration an Indemnified Person is permitted or
required to make a decision:

          (i) in its "discretion" or under a grant of similar authority the
     Indemnified Person shall be entitled to consider such interests and factors
     as it desires, including its own interests, and shall have no duty or
     obligation to give any consideration to any interest of or factors
     affecting the Trust or any other Person; or

          (ii) in its "good faith" or under another express standard, the
     Indemnified Person shall act under such express standard and shall not be
     subject to any other or different standard imposed by this Declaration or
     by applicable law.

     Section 10.04.  INDEMNIFICATION.

          (a) (i) The Sponsor shall indemnify, to the full extent permitted by
     law, any Company Indemnified Person who was or is a party or is threatened
     to be made a party to any threatened, pending or completed action, suit or
     proceeding, whether civil, criminal, administrative or investigative (other
     than an action by or in the right of the Trust) by reason of the fact that
     he is or was a Company Indemnified Person against expenses (including
     attorneys' fees), judgments, fines and amounts paid in settlement actually
     and reasonably incurred by him in connection with such action, suit or
     proceeding if he acted in good faith and in a manner he reasonably believed
     to be in or not opposed to the best interests of the Trust, and, with
     respect to any criminal action or proceeding, had no reasonable cause to
     believe his conduct was unlawful. The termination of any action, suit or
     proceeding by judgment, order, settlement, conviction, or upon a plea of
     nolo contendere or its equivalent, shall not, of itself, create a
     presumption that the Company Indemnified Person did not act in good faith
     and in a manner which he reasonably believed to be in or not opposed to the
     best interests of the Trust, and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that his conduct was unlawful.

          (ii) The Sponsor shall indemnify, to the full extent permitted by law,
     any Company Indemnified Person who was or is a party or is threatened to be
     made a party to any threatened, pending or completed action or suit by or
     in the right of the Trust to procure a judgment in its favor by reason of
     the fact that he is or was a Company Indemnified Person against expenses
     (including attorneys' fees) actually and reasonably incurred by him in
     connection with the defense or settlement of such action or suit if he
     acted in good faith and in a manner he reasonably believed to be in or not
     opposed to the best interests of the Trust and except that no such
     indemnification shall be made in respect of any claim, issue or matter as
     to which such Company Indemnified Person shall have been adjudged to be
     liable to the Trust unless and only to the extent that the Court of
     Chancery of Delaware or the court in which such action or suit was brought
     shall determine upon application that, despite the adjudication of
     liability but in view of all the circumstances of the case, such person is
     fairly and reasonably entitled to indemnity for such expenses which such
     Court of Chancery or such other court shall deem proper.

                                       36
<PAGE>
 
          (iii)  To the extent that a Company Indemnified Person shall be
     successful on the merits or otherwise (including dismissal of an action
     without prejudice or the settlement of an action without admission of
     liability) in defense of any action, suit or proceeding referred to in
     paragraphs (i) and (ii) of this Section 10.04(a), or in defense of any
     claim, issue or matter therein, he shall be indemnified, to the full extent
     permitted by law, against expenses (including attorneys' fees) actually and
     reasonably incurred by him in connection therewith.

          (iv) Any indemnification under paragraphs (i) and (ii) of this Section
     10.04(a) (unless ordered by a court) shall be made by the Sponsor only as
     authorized in the specific case upon a determination that indemnification
     of the Company Indemnified Person is proper in the circumstances because he
     has met the applicable standard of conduct set forth in paragraphs (i) and
     (ii). Such determination shall be made (1) by the Regular Trustees by a
     majority vote of a quorum consisting of such Regular Trustees who were not
     parties to such action, suit or proceeding, (2) if such a quorum is not
     obtainable, or, even if obtainable, if a quorum of disinterested Regular
     Trustees so directs, by independent legal counsel in a written opinion, or
     (3) by the Common Security Holder of the Trust.

          (v) Expenses (including attorneys' fees) incurred by a Company
     Indemnified Person in defending a civil, criminal, administrative or
     investigative action, suit or proceeding referred to in paragraphs (i) and
     (ii) of this Section 10.04(a) shall be paid by the Sponsor in advance of
     the final disposition of such action, suit or proceeding upon receipt of an
     undertaking by or on behalf of such Company Indemnified Person to repay
     such amount if it shall ultimately be determined that he is not entitled to
     be indemnified by the Sponsor as authorized in this Section 10.04(a).
     Notwithstanding the foregoing, no advance shall be made by the Sponsor if a
     determination is reasonably and promptly made (i) by the Regular Trustees
     by a majority vote of a quorum of disinterested Regular Trustees, (ii) if
     such a quorum is not obtainable, or, even if obtainable, if a quorum of
     disinterested Regular Trustees so directs, by independent legal counsel in
     a written opinion or (iii) the Common Security Holder of the Trust, that,
     based upon the facts known to the Regular Trustees, counsel or the Common
     Security Holder at the time such determination is made, such Company
     Indemnified Person acted in bad faith or in a manner that such person did
     not believe to be in or not opposed to the best interests of the Trust, or,
     with respect to any criminal proceeding, that such Company Indemnified
     Person believed or had reasonable cause to believe his conduct was
     unlawful. In no event shall any advance be made in instances where the
     Regular Trustees, independent legal counsel or Common Security Holder
     reasonably determine that such person deliberately breached his duty to the
     Trust or its Common or Trust Preferred Security Holders.

          (vi) The indemnification and advancement of expenses provided by, or
     granted pursuant to, the other paragraphs of this Section 10.04(a) shall
     not be deemed exclusive of any other rights to which those seeking
     indemnification and advancement of expenses may be entitled under any
     agreement, vote of stockholders or disinterested directors of the Sponsor
     or Trust Preferred Security Holders of the Trust or otherwise, both as to
     action in his official capacity and as to action in another capacity while
     holding such office. All rights to indemnification under this Section
     10.04(a) shall be deemed to be provided by a contract between the Sponsor
     and each Company Indemnified Person who serves in such capacity at 

                                       37
<PAGE>
 
     any time while this Section 10.04(a) is in effect. Any repeal or
     modification of this Section 10.04(a) shall not affect any rights or
     obligations then existing.

          (vii)  The Sponsor or the Trust may purchase and maintain insurance on
     behalf of any Person who is or was a Company Indemnified Person against any
     liability asserted against him and incurred by him in any such capacity, or
     arising out of his status as such, whether or not the Sponsor would have
     the power to indemnify him against such liability under the provisions of
     this Section 10.04(a)

          (viii)  For purposes of this Section 10.04(a), references to "the
     Trust" shall include, in addition to the resulting or surviving entity, any
     constituent entity (including any constituent of a constituent) absorbed in
     a consolidation or merger, so that any person who is or was a director,
     trustee, officer or employee of such constituent entity, or is or was
     serving at the request of such constituent entity as a director, trustee,
     officer, employee or agent of another entity, shall stand in the same
     position under the provisions of this Section 10.04(a) with respect to the
     resulting or surviving entity as he would have with respect to such
     constituent entity if its separate existence had continued.

          (ix) The indemnification and advancement of expenses provided by, or
     granted pursuant to, this Section 10.04(a) shall, unless otherwise provided
     when authorized or ratified, continue as to a person who has ceased to be a
     Company Indemnified Person and shall inure to the benefit of the heirs,
     executors and administrators of such a person.

     (b) The Sponsor agrees to indemnify, to the fullest extent permitted by
law, (i) the Institutional Trustee, (ii) the Delaware Trustee, (iii) the Paying
Agent, (iv) the Conversion Agent, (v) any Affiliate of the Institutional
Trustee, and the Delaware Trustee, and (vi) any officers, directors,
shareholders, members, partners, employees, representatives, custodians,
nominees or agents of the Institutional Trustee, the Paying Agent, the
Conversion Agent and the Delaware Trustee (each of the Persons in (i) through
(vi) being referred to as a "Fiduciary Indemnified Person") for, and to hold
each Fiduciary Indemnified Person harmless against, any loss, liability or
expense incurred without negligence or bad faith on its part, arising out of or
in connection with the acceptance or administration or the trust or trusts
hereunder, including the costs and expenses (including reasonable legal fees and
expenses) of defending itself against or investigating any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder. The Sponsor also agrees to advance expenses (including legal fees)
incurred by a Fiduciary Indemnified Person in defending any claim, demand,
action, suit or proceeding, from time to time, prior to the final disposition of
such claim, demand, action, suit or proceeding upon receipt by the Sponsor of an
undertaking by or on behalf of the Fiduciary Indemnified Person to repay such
amount if it shall be determined that the Fiduciary Indemnified Person is not
entitled to be indemnified as authorized in the preceding subsection. The
obligation to indemnify as set forth in this Section 10.04(b) shall survive the
satisfaction and discharge of this Declaration.

     Section 10.05.  OUTSIDE BUSINESS.

     Any Covered Person, the Sponsor, the Delaware Trustee and the Institutional
Trustee may engage in or possess an interest in other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Trust, and the Trust and the Holders of Securities shall
have no rights by virtue of this Declaration in and to such independent ventures
or the income or profits derived therefrom, and the pursuit of any such venture,
even if competitive with the business of the Trust, shall not be deemed wrongful
or improper. No Covered Person, the Sponsor, the Delaware Trustee, or the
Institutional Trustee shall be obligated to present any particular investment or
other opportunity to the Trust even if such opportunity is of a character that,
if presented to the Trust, could be taken by the Trust, and any Covered Person
shall have the right to take for its own account (individually or as a partner
or fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Covered Person, the Delaware Trustee and the Institutional
Trustee may engage or be interested in any financial or other transaction with
the Sponsor or any Affiliate of the Sponsor, or may act as depositary for,
trustee or agent for, or act on any committee or body of holders of, securities
or other obligations of the Sponsor of its Affiliates.

                                   ACCOUNTING

     Section 11.01.  FISCAL YEAR.

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

     Section 11.02.  CERTAIN ACCOUNTING MATTERS.

     (a)  At all times during the existence of the Trust, the Regular Trustees
shall keep, or cause to be kept, full books, records and supporting documents,
which shall reflect in detail, each transaction of the Trust. The books of
account shall be maintained on the accrual method of accounting in compliance
with generally accepted accounting principles, consistently applied. The Trust
shall use the accrual method of accounting for the United States federal income
tax purposes. The books of account and the records of the Trust shall be
examined by and reported upon as of the end of each Fiscal Year of the Trust by
a firm of independent certified public accountants selected by the Regular
Trustees.

     (b) The Regular Trustees shall cause to be prepared and delivered to each
of the Holders of Securities and the other Trustees, within 90 days after the
end of each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related income or loss.

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

                                       39
<PAGE>
 
Regular Trustees shall endeavor to deliver all such statements within 30 days
after the end of each Fiscal Year of the Trust.

     (d) The Regular Trustees shall cause to be duly prepared and filed with the
appropriate taxing authority, an annual United States federal income tax return,
on a Form 1041 or such other form required by United States federal income tax
law, and any other annual income tax returns required to be filed by the Regular
Trustees on behalf of the Trust with any state or local taxing authority.

     Section 11.03.  BANKING.

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

     Section 11.04.  WITHHOLDING.
 
     The Trust and the Regular Trustees shall comply with all withholding
requirements under United States federal, state and local law. The Trust shall
request, and the Holders shall provide to the Trust, such forms or certificates
as are necessary to establish an exemption from withholding with respect to each
Holder, and any representations and forms as shall reasonably be requested by
the Trust to assist it in determining the extent of, and in fulfilling, its
withholding obligations. The Regular Trustees shall file required forms with
applicable jurisdictions and, unless an exemption from withholding is properly
established by a Holder, shall remit amounts withheld with respect to the Holder
to applicable jurisdictions. To the extent that the Trust is required to
withhold and pay over any amounts to any authority with respect to distributions
or allocations to any Holder, the amount withheld shall be deemed to be a
distribution in the amount of the withholding to the Holder. In the event of any
claimed over-withholding, Holders shall be limited to an action against the
applicable jurisdiction. If the amount required to be withheld was not withheld
from actual Distributions made, the Trust may reduce subsequent Distributions by
the amount of such withholding.

CONSENT.

     (a) Meetings of the Holders of any class of Securities may be called at any
time by the Regular Trustees (or as provided in the terms of the Securities) to
consider and act on any matter on which Holders of such class of Securities are
entitled to act under the terms of this Declaration, the terms of the Securities
or the rules of any stock exchange on which the Trust Preferred Securities are
listed or admitted for trading. The Regular Trustees shall call a meeting of the
Holders of such class if directed to do so by the Holders of at least 10% in
liquidation amount of such class of Securities. Such direction shall be given by
delivering to the Regular Trustees one or more calls in a writing stating that
the signing Holders of Securities wish to call a meeting and indicating the
general or specific purpose for which the meeting is to be called. Any Holders
of Securities calling a meeting shall specify in writing the Security
Certificates held by the Holders of Securities exercising the right to call a
meeting and only those Securities specified shall be counted for purposes of
determining whether the required percentage set forth in the second sentence of
this paragraph has been met.

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

          (i) notice of any such meeting shall be given to all the Holders of
     Securities having a right to vote thereat at least 7 days and not more than
     60 days before the date of such meeting. Whenever a vote, consent or
     approval of the Holders of Securities is permitted or required under this
     Declaration or the rules of any stock exchange on which the Trust Preferred
     Securities are listed or admitted for trading, such vote, consent or
     approval may be given at a meeting of the Holders of Securities. Any action
     that may be taken at a meeting of the Holders of Securities may be taken
     without a meeting if a consent in writing setting forth the action so taken
     is signed by the Holders of Securities owning not less than the minimum
     amount of Securities in liquidation amount that would be necessary to
     authorize or take such action at a meeting at which all Holders of
     Securities having a right to vote thereon were present and voting. Prompt
     notice of the taking of action without a meeting shall be given to the
     Holders of Securities entitled to vote 

                                       42
<PAGE>
 
     who have not consented in writing. The Regular Trustees may specify that
     any written ballot submitted to the Security Holder for the purpose of
     taking any action without a meeting shall be returned to the Trust within
     the time specified by the Regular Trustees;

          (ii) each Holder of a Security may authorize any Person to act for it
     by proxy on all matters in which a Holder of Securities is entitled to
     participate, including waiving notice of any meeting, or voting or
     participating at a meeting. No proxy shall be valid after the expiration of
     11 months from the date thereof unless otherwise provided in the proxy.
     Every proxy shall be revocable at the pleasure of the Holder of Securities
     executing it. Except as otherwise provided herein, all matters relating to
     the giving, voting or validity of proxies shall be governed by the General
     Corporation Law of the State of Delaware relating to proxies, and judicial
     interpretations thereunder, as if the Trust were a Delaware corporation and
     the Holders of the Securities were stockholders of a Delaware corporation;

          (iii)  each meeting of the Holders of the Securities shall be
     conducted by the Regular Trustees or by such other Person that the Regular
     Trustees may designate; and

          (iv) unless the Business Trust Act, this Declaration, the terms of the
     Securities, the Trust Indenture Act or the listing rules of any stock
     exchange on which the Trust Preferred Securities are then listed or
     trading, otherwise provides, the Regular Trustees, in their sole
     discretion, shall establish all other provisions relating to meetings of
     Holders of Securities, including notice of the time, place or purpose of
     any meeting at which any matter is to be voted on by any Holders of
     Securities, waiver of any such notice, action by consent without a meeting,
     the establishment of a record date, quorum requirements, voting in person
     or by proxy or any other matter with respect to the exercise of any such
     right to vote.
