         subordinated unsecured debt securities in one or more series.

         supplement to this prospectus.

         underwriters, dealers or agents or through any combination of these
         methods.
 
*        A supplement to this prospectus will name any underwriters, dealers or
         agents involved in the sale of our debt securities and describe their
         compensation.

                             ABOUT THIS PROSPECTUS
 
This prospectus is part of a registration statement that we filed with the
Securities and Exchange Commission utilizing a "shelf" registration process.
Under this shelf process, we may, over the next two years, use the registration
statement and the shelf process to sell any combination of the debt securities
described in this prospectus in one or more offerings up to a total dollar
amount of $500,000,000. This prospectus provides you with a general description
of the debt securities we may offer. Each time we sell debt securities, we will
provide a prospectus supplement that will contain specific information about the
terms of that offering. The prospectus supplement may also add, update or change
information contained in this prospectus. It is important for you to carefully
read both this prospectus and any prospectus supplement together with additional
information described under the heading "Where You Can Find More Information" in
making your investment decision.
 
For more detail, you should read the exhibits filed with our registration
statement.
 
                      WHERE YOU CAN FIND MORE INFORMATION
 
We file annual, quarterly and special reports and other information with the
SEC. Our SEC filings are available to the public over the internet at the SEC's
web site at http://www.sec.gov. You may also read and copy any document we file
at the SEC's public reference rooms in Washington, D.C., New York, New York, and
Chicago, Illinois. Please call the SEC at 1-800-SEC-0330 for further information
on the public reference rooms.
 
The SEC allows us to "incorporate by reference" the information we file with
them, which means that we can disclose important information to you by referring
you to those documents. The information incorporated by reference is an
important part of this prospectus, and information that we file later with the
SEC will automatically update and supersede this information. We incorporate by
reference the documents listed below and any future filings made by us with the
SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of
1934 until we or the underwriters sell all of the securities that we have
registered.

                       SPECIAL NOTE OF CAUTION REGARDING
                           FORWARD-LOOKING STATEMENTS
 
Certain statements in (a) this prospectus under the caption "Risk Factors," (b)
any applicable prospectus supplement and (c) the documents incorporated by
reference into this prospectus may constitute "forward-looking statements"
within the meaning of federal securities laws. Forward-looking statements are
based on our management's beliefs, assumptions, and expectations of our future
economic performance, taking into account the information currently available to
them. These statements are not statements of historical fact. Forward-looking
statements involve risks and uncertainties that may cause our actual results,
performance or financial condition to be materially different from the
expectations of future results, performance or financial condition we express or
imply in any forward-looking statements. Some of the important factors that
could cause our actual results, performance or financial condition to differ
materially from our expectations are:
 
*         Fluctuations in our costs to maintain and update our fleet and
          facilities;
 
*         Changes in government regulations, particularly environmental
          regulations;
 
*         Changes in demand for our products;
 
*         Changes in the general domestic economy;
 
*         Degree and nature of our competition; and
 
*         Other factors described in this prospectus, any prospectus supplement
          or the documents we file with the SEC and incorporate by reference
          into this prospectus.
 
When used in our documents or oral presentations, the words "anticipate,"
"estimate," "expect," "objective," "projection," "forecast," "goal" or similar
words are intended to identify forward-looking statements. We qualify any such
forward-looking statements entirely by these cautionary factors.

                                  ABOUT AMERCO
 
GENERAL INFORMATION
 
AMERCO owns all of the stock of our principal subsidiary, U-Haul International,
Inc. U-Haul rental operations represented over 80% of our total revenue for each
of the past five (5) fiscal years ended March 31, 1998. We also own all the
stock of Republic Western Insurance Company, Oxford Life Insurance Company, and
Amerco Real Estate Company. Throughout this prospectus, unless otherwise
indicated, AMERCO and references to "we," "our," "ours" and "us" includes all of
our subsidiaries. Our principal executive offices are located at 1325 Airmotive
Way, Suite 100, Reno, Nevada 89502, and our telephone number is (775) 688-6300.
 
U-HAUL OPERATIONS
 
*         U-Move Operations
 
Founded in 1945, U-Haul is primarily engaged, through its subsidiaries, in the
rental of trucks, automobile-type trailers, and support rental items to the
do-it-yourself moving customer. Our do-it-yourself moving business operates
under the U-Haul name through an extensive and geographically diverse
distribution network of approximately 1,100 company-owned U-Haul centers and
approximately 15,000 independent dealers throughout the United States and
Canada. We believe that we have more moving equipment rental locations than our
two largest competitors combined. The U-Haul rental equipment fleet consists of
92,900 trucks, 79,600 trailers, and 18,300 tow dollies. Additionally, U-Haul
sells related products (such as boxes, tape, and packaging materials) and rents
various kinds of equipment (such as floor polishing and carpet cleaning
equipment).
 
*         Self-Storage Rental Operations
 
U-Haul entered the self-storage business in 1974 and offers for rent more than
27.2 million square feet of self-storage space through over 800 company-owned or
managed storage locations. We believe we are the second largest self-storage
operator (in terms of square feet) in the industry. We believe our self-storage
operations are complementary to the do-it-yourself moving business. All of our
self-storage space is located at or near one or more U-Haul centers or
independent U-Haul dealers.

INSURANCE OPERATIONS
 
*         Republic Western
 
Republic Western originates and reinsures property and casualty type insurance
products for independent third parties, U-Haul customers, and U-Haul. Republic
Western's principal strategy is to capitalize on its knowledge of insurance
products aimed at the moving and rental markets. Approximately 29.8% of Republic
Western's written premiums relate to insurance underwriting activities involving
AMERCO's affiliates. Approximately 90.8% of Republic Western's invested assets
are in investment grade (NAIC-2 or greater) fixed income securities. Republic
Western is rated "A+-VIII" by A.M. Best.
 
*         Oxford
 
Oxford primarily reinsures life, health, and annuity insurance products and
administers our self-insured employee health plan. Approximately 2.9% of
Oxford's premium revenues are from business with AMERCO's affiliates.
Approximately 91.4% of Oxford's invested assets are in investment grade (NAIC-2
or greater) fixed income securities. Oxford is rated "A-VII" by A.M. Best.
 
REAL ESTATE OPERATIONS
 
*         Amerco Real Estate
 
Amerco Real Estate owns or actively manages over 1,150 properties throughout the
United States and Canada. In addition to its U-Haul operations, Amerco Real
Estate actively seeks to lease or dispose of our surplus properties.

                                  THE OFFERING
 
We may offer and sell from time to time, in one or more series, unsecured senior
or subordinated debt securities, which may consist of notes, debentures or other
evidences of indebtedness.
 
The total initial offering prices of the debt securities we may offer and sell
pursuant to this prospectus and supplements to it will not be greater than
$500,000,000 (or the equivalent amount in a foreign currency or currency unit at
the time of sale). We will offer these securities in amounts, at prices and on
terms that we determine in light of market conditions at the time of sale and
specify in a prospectus supplement.

                                  RISK FACTORS
 
*         HIGHLY COMPETITIVE INDUSTRY
 
The truck rental industry is highly competitive and includes a number of
significant national and hundreds of regional and local competitors. Competition
is generally based on price, product quality, convenience, availability, brand
name recognition and service. Competition could adversely affect AMERCO's
operating results by forcing us to reduce prices or delay price increases.
 
*         MANAGEMENT'S DISCRETION AS TO USE OF PROCEEDS
 
We will use the net proceeds from the sale of the debt securities in the manner
set forth in the prospectus supplement relating to each offering of the debt
securities. Consequently, our Board of Directors and management will have broad
discretion in allocating the net proceeds of this offering.
 
*         CONTROL BY CERTAIN EXISTING STOCKHOLDERS
 
Edward J. Shoen, Chairman of the Board and President of AMERCO, James P. Shoen,
Vice President and a Director of AMERCO, and Mark V. Shoen, President of U-Haul
Phoenix Operations collectively own 9,205,476 shares (approximately 40.1%) of
the outstanding common stock of AMERCO. Accordingly, Edward J. Shoen, Mark V.
Shoen, and James P. Shoen will be in a position to continue to influence the
election of the members of the Board of Directors and decisions requiring
stockholder approval. In addition, 2,849,124 shares (approximately 12.6%),
including shares allocated to employees and unallocated shares, are held by the
AMERCO Employee Savings and Employee Stock Ownership Trust.
 
*         ENVIRONMENTAL MATTERS
 
Compliance with environmental requirements of federal, state and local
governments significantly affects AMERCO's business. Among other things, these
requirements regulate the discharge of materials into the water, air and land
and govern the use and disposal of hazardous substances. Under environmental
laws, AMERCO can be held strictly liable for hazardous substances that are found
on real property AMERCO has owned or operated. AMERCO is aware of issues
regarding hazardous substances on some of our real estate and AMERCO has put in
place a remedial plan at each site where we believe such a plan is necessary.
AMERCO regularly makes capital and operating expenditures to stay in compliance
with environmental laws. In particular, AMERCO has managed a testing and removal
program since 1988 for our underground storage tanks. Under this program, AMERCO
has removed over 3,000 tanks at a total cost of $39.0 million since April 1988.
As of December 31, 1998, AMERCO has twelve known sites containing thirteen known
underground storage tanks. Despite these compliance efforts, risk of
environmental liability is part of the nature of our business. AMERCO cannot
assure you that environmental liabilities, including compliance and remediation
costs, will not have a material adverse effect on AMERCO in the future. In
addition, future events may lead to additional compliance or other costs that
could have a material adverse effect on AMERCO. Such future events could include
changes in, or new interpretations of, existing laws or enforcement policies.

*         YEAR 2000 DISCLOSURE
 
AMERCO is and has been working since 1997 to identify and complete the changes
necessary to our existing computerized business systems to make these systems
compliant for Year 2000 processing. The Year 2000 processing problem is caused
by currently installed computer systems and software products, including several
used by AMERCO, being coded to accept only the last two digit entries in the
date code field instead of four digits to indicate the year. Such programs may
interpret the year 2000 to mean 1900 instead, producing erroneous information or
date-related computer failures.
 
AMERCO's date reliance functions related to the Year 2000 and beyond, such as
rental transaction processing and financial systems, may be adversely affected
unless these computer systems are or become Year 2000 compliant. Replacing,
upgrading or modifying key financial systems has been on-going in the normal
course of business. AMERCO is utilizing both internal and external resources to
identify, correct, reprogram and test our systems for Year 2000 compliance. In
particular, AMERCO has an outside consulting firm on-site currently making the
Year 2000 compliance related modifications to existing systems. The assessment
phase is complete for information technology. AMERCO's internal information
technology conversion phase is underway, with the testing phase going on at the
same time.
 
AMERCO is also assessing our non-information technology items for Year 2000
compliance, such as rental vehicles and storage facilities security systems.
 
AMERCO is communicating with our major business partners to determine the
efforts being made on their part for compliance. Critical vendors with
electronic data interchange will be scheduled for testing between January and
March of 1999, with other vendor testing to be scheduled during the remainder of
the calendar year 1999. There can be no assurance AMERCO will not be adversely
affected by the failure of others to become Year 2000 compliant. For example,
AMERCO may be affected by, among other things, the failure of inventory
suppliers, credit card processors, security companies or other vendors and
service providers to become Year 2000 compliant.
 
AMERCO expects to be Year 2000 compliant by the fall of calendar year 1999.
Initially, the budget was $2.0 million; as the conversion process continues, we
now anticipate an additional $0.8 million may be incurred. Through December 31,
1998, $1.4 million has been incurred. AMERCO is accelerating the replacement of
our payroll system due to year 2000 non-compliance at an estimated cost of $0.3
million to be incurred starting in June 1999. AMERCO has not deferred any major
computer programming or update projects due to Year 2000 efforts. Although
AMERCO believes we will achieve compliance on a timely basis, no assurance can
be given that AMERCO's computer systems will be Year 2000 compliant by the fall
of 1999 or otherwise in a timely manner or that AMERCO will not incur
significant additional costs pursuing Year 2000 compliance. If the appropriate
modifications are not made, or are not timely, the Year 2000 problem may have a
material adverse effect on AMERCO.
 
                                        8
<PAGE>   12
 
AMERCO considers our most reasonably likely worst case scenario to be if a
business partner is not Year 2000 compliant. AMERCO is in the process of
developing and refining contingency plans to be used if a business partner is
not compliant. The contingency plans will include processing of rental
transactions, payments to employees and vendors, licensing of equipment,
preparation of financial statements and the movement of funds. It is anticipated
that the contingency plans will be completed by the end of March of 1999, with
refinement continuing until the year 2000.
 
Despite AMERCO's efforts to date, there can be no assurance that the Year 2000
problem will not have a material adverse effect on AMERCO in the future.
 
                                USE OF PROCEEDS
 
The use of proceeds from the sale of the debt securities will be set forth in a
prospectus supplement relating to each offering of debt securities.

                       RATIO OF EARNINGS TO FIXED CHARGES
 
The following table shows AMERCO's ratio of earnings to fixed charges for the
periods indicated. For purposes of computing the ratio of earnings to fixed
charges, "earnings" consists of pretax earnings from operations plus total fixed
charges excluding interest capitalized during the period, and "fixed charges"
consists of interest expense, capitalized interest, amortization of debt expense
and discounts, and one-third of the our annual rental expense (which we believe
is a reasonable approximation of the interest factor of these rentals). The
ratio for the nine months ended on December 31, 1998 may be different from the
ratio for fiscal 1999 because, among other reasons, U-Haul rental operations are
seasonal and proportionally more of our earnings are generated in the first and
second quarters of each fiscal year.

                         DESCRIPTION OF DEBT SECURITIES
 
The following is a description of certain general terms of the debt securities
to which any prospectus supplement may relate. The particular terms of the debt
securities, including the senior securities and the subordinated securities,
offered by any prospectus supplement (the "Offered Securities") and the extent,
if any, to which such general provisions may apply to the debt securities so
offered will be described in the prospectus supplement relating to such Offered
Securities.
 
The senior securities are to be issued under an indenture (the "Senior
Indenture"), between AMERCO and The Bank of New York, as trustee (the "Senior
Trustee"). The subordinated securities are to be issued under an Indenture (the
"Subordinated Indenture") between AMERCO and The Bank of New York, as trustee
(the "Subordinated Trustee," together with the Senior Trustee, the "Trustees").
The Senior Indenture and the Subordinated Indenture (collectively, the
"Indentures") are exhibits to the registration statement. The following
summaries of certain provisions of the Indentures do not purport to be complete
and are subject to, and are qualified in their entirety by reference to, all
provisions of the Indentures, including the definitions therein of certain
terms. Because this is a summary, it does not contain all the information that
may be important to you. You should read each of the applicable Indentures in
their entirety, including the definitions of certain terms, and the applicable
prospectus supplement before you make any investment decision. Wherever
particular provisions or defined terms of the Indentures are referred to, such
provisions or defined terms are incorporated herein by reference. Certain
defined terms in the Indentures are capitalized herein.

                                    GENERAL
 
Unless otherwise indicated in the prospectus supplement relating to Offered
Securities, the debt securities will be unsecured obligations of AMERCO.
 
The Indentures do not limit the amount of Offered Securities that may be issued
thereunder and provide that the Offered Securities may be issued thereunder from
time to time in one or more series. All Offered Securities of one series need
not be issued at the same time and, unless otherwise provided, a series may be
reopened under the applicable Indenture, without the consent of any holder, for
issuances of additional Offered Securities of such series. The senior securities
will rank pari passu with all other unsecured and unsubordinated indebtedness of
AMERCO. The subordinated securities will rank pari passu with other subordinated
indebtedness of AMERCO and, together with such subordinated indebtedness, will
be subordinated in right of payment to the prior payment in full of all Senior
Indebtedness of AMERCO as described under "Subordinated Securities" below.
 
Reference is made to the prospectus supplement relating to the Offered
Securities for the following terms, where applicable, of the Offered Securities:
 
       *         the title of the Offered Securities;
 
       *         any limit on the aggregate principal amount of the Offered

                 registered at the close of business on the regular record date
                 for such interest;
 
       *         the date or dates on which the Offered Securities will mature;
 
       *         the rate or rates (which may be fixed or variable) at which the
                 Offered Securities will bear interest, if any, and the date or
                 dates from which such interest will accrue;
 
       *         the dates on which such interest, if any, will be payable and
                 the regular record dates for such interest payment dates;

                 registration of transfer or exchange and where notices to or
                 demand upon AMERCO may be delivered;
 
       *         the period or periods within which, the price or prices at
                 which, and the terms and conditions upon which, the Offered
                 Securities may be redeemed in whole or in part, at the option
                 of AMERCO;
 
       *         the mandatory or optional redemption provisions applicable to
                 the Offered Securities;
 
                                       11
<PAGE>   15
 
       *         the obligation, if any, of AMERCO to redeem or purchase such
                 Offered Securities pursuant to any sinking fund or analogous

       *         any additional restrictive covenants under the applicable
                 Indenture;
 
       *         the right of AMERCO to defease the Offered Securities or
                 certain restrictive covenants and certain Events of Default
                 under the Indentures;
 
       *         the currency or currencies in which payment of principal and
                 premium, if any, and interest on the Offered Securities will be
                 payable, if other than United States dollars;
 
       *         if the principal of and premium, if any, or interest, if any,
                 on such Offered Securities is to be payable, at the election of
                 AMERCO or a holder thereof, in a currency or currencies other
                 than that in which such Offered Securities are stated to be
                 payable, the currency or currencies in which payment of the
                 principal of and premium, if any, or interest, if any, on such
                 Offered Securities as to which such election is made will be
                 payable and the period or periods within which, and the terms
                 and conditions upon which, such election may be made;
 
       *         any index used to determine the amount of payments of principal
                 of and premium, if any, and interest, if any, on the Offered
                 Securities;
 
       *         if the Offered Securities will be issuable only in the form of
                 a global note as described under "Book-Entry Securities," the
                 Depository or its nominee with respect to the Offered
                 Securities, and the circumstances under which the global note
                 may be registered for transfer or exchange in the name of a
                 person other than the Depository or its nominee;
 
       *         any additional Events of Default under the applicable
                 Indenture; and
 
       *         any other terms of the Offered Securities.
 
If the principal of and premium, if any, or any interest on Offered Securities
of any series are payable in a foreign or composite currency, the restrictions,
elections, federal income tax consequences, specific terms and other information

                                       12
<PAGE>   16
 
payable, and the Offered Securities will be exchangeable and transfers thereof
will be registrable, at the office of the applicable Trustee at 101 Barclay
Street, Floor 21 West, New York, New York, 10286, provided that, at the option
of AMERCO, payment of interest may be made by:
 
       *         wire transfer on the date of payment in immediately available
                 federal funds or next day funds to an account specified by
                 written notice to the applicable Trustee from any holder of
                 Offered Securities;
 
       *         any similar manner that such holder may designate in writing to
                 the applicable Trustee; or
 
       *         by check mailed to the address of the person entitled thereto
                 as it appears in the security register.
 
Any payment of principal and premium, if any, and interest, if any, required to
be made on an interest payment date, redemption date, or at maturity that is not
a business day need not be made on such day, but may be made on the next
succeeding business day with the same force and effect as if made on the
interest payment date, redemption date, or at maturity, as the case may be, and
no interest shall accrue for the period from and after such interest payment
date, redemption date, or maturity.
 
Unless otherwise indicated in the prospectus supplement relating to Offered
Securities, the debt securities will be issued only in fully registered form,
without coupons, in denominations of $1,000 or any integral multiple thereof. No
service charge will be made for any transfer or exchange of Offered Securities,
but AMERCO may require payment of a sum sufficient to cover any tax or other
government charge payable in connection therewith.
 
Offered Securities may be issued under the Indentures as original issue discount
securities to be offered and sold at a substantial discount from their stated
principal amount. In addition, under United States treasury regulations, it is
possible that Offered Securities that are offered and sold at their stated
principal amount would, under certain circumstances, be treated as issued at an
original issue discount for federal income tax purposes. Federal income tax
consequences and other special considerations applicable to any such original
issue discount securities (or other debt securities treated as issued at an
original issue discount) and to "investment units" will be described in the
prospectus supplement relating thereto. An "original issue discount security"
means any security that provides for an amount less than the principal amount
thereof to be due and payable upon a declaration of acceleration of the maturity
thereof upon the occurrence of an Event of Default and the continuation thereof.
 
                               BOOK-ENTRY SYSTEM
 
The debt securities will be represented by one or more permanent global notes
deposited with, or on behalf of, The Depository Trust Company, as Depository
under the Indentures
 
                                       13
<PAGE>   17
 
and the related supplemental indentures (the "Depository"), and registered in
the name of the Depository's nominee. Except as set forth below:
 
       *         owners of beneficial interests in a global note will not be
                 entitled to have debt securities represented by such global
                 note registered in their names, will not receive or be entitled
                 to receive physical delivery of notes in definitive form and
                 will not be considered the owners or holders thereof under the
                 Indentures and the related Supplemental Indentures; and
 
       *         each global note may be transferred, in whole and not in part,
                 only to another nominee of the Depository or to a successor of
                 the Depository or its nominee.
 
Accordingly, beneficial interests in the debt securities will be shown on, and
transfers thereof will be effected only through, records maintained by the
Depository and its participants. The laws of some states require certain
purchasers of securities to take physical delivery thereof in definitive form.
The depository arrangements described above and such laws may impair the ability
to own or transfer beneficial interests in a global note.
 
Owners of beneficial interests in any global note will not be entitled to
receive debt securities in definitive form and will not be considered holders of
debt securities unless:
 
       *         the Depository notifies AMERCO that it is unwilling or unable
                 to continue as Depository for such global note or if at any
                 time the Depository ceases to be a clearing agency registered
                 under the Exchange Act;
 
       *         AMERCO executes and delivers to the applicable Trustee a
                 company order that such global note shall be so exchangeable;
                 or
 
       *         there shall have occurred and be continuing an Event of Default
                 or an event which, with the giving of notice or lapse of time,
                 or both, would constitute an Event of Default with respect to
                 the debt securities (a "Default").
 
In such circumstances, upon surrender by the Depository or a successor
depository of any global note, debt securities in definitive form will be issued
to each person that the Depository or a successor depository identifies as the
beneficial owner of the related debt securities. Upon such issuance, the
applicable Trustee is required to register such debt securities in the name of,
and cause such debt securities to be delivered to, such person or persons (or
nominees thereof). Such debt securities would be issued in fully registered form
without coupons, in denominations of $1,000 and integral multiples thereof.
 
The Depository is a limited-purpose trust company organized under the laws of
the State of New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. The
Depository was created to hold securities for its participants and to facilitate
the clearance and settlement of securities transactions among its participants
in such securities through electronic book-entry changes in accounts of the
participants, thereby eliminating the need for physical movement of securities
certificates. The Depository's direct participants include securities brokers
and dealers, banks, trust companies, clearing corporations, and certain other
organizations, some of whom (and/or their representatives) own the Depository.
Access to the Depository's book-entry system is also available to others known
as indirect participants, such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship
                                       14
<PAGE>   18
 
with a participant, either directly or indirectly. The Depository agrees with
and represents to its participants that it will administer its book-entry system
in accordance with its rules and by-laws and requirements of law.
 
Principal and interest payments on debt securities registered in the name of or
held by the Depository or its nominee will be made to the Depository or its
nominee, as the case may be, as the registered owner of the global note
representing such debt securities. Under the terms of the Indentures and the
related Supplemental Indentures, AMERCO and the applicable Trustee will treat
the persons in whose names the debt securities are registered as the holders of
such debt securities for the purpose of receiving payment of principal and
interest on such debt securities and for all other purposes whatsoever.
Therefore, none of AMERCO, the Trustees or any paying agent has any direct
responsibility or liability for the payment of principal of or interest on the
debt securities to owners of beneficial interests in any global note. The
Depository has advised AMERCO and the Trustees that its current practice is to
credit the accounts of participants with payments of principal or interest on
the date payable in amounts proportionate to their respective holdings in
principal amount of beneficial interests in a global note as shown in the
records of the Depository, unless the Depository has reason to believe that it
will not receive payment on such date. The Depository's current practice is to
credit such accounts, as to interest, in next-day funds and, as to principal, in
same-day funds. Payments by participants and indirect participants to owners of
beneficial interests in a global note will be governed by standing instructions
and customary practices, as is now the case with securities held for the
accounts of customers in bearer form or registered in "street name" and will be
the responsibility of the participants and indirect participants.
 
The Depository has advised AMERCO that it will take any action permitted to be
taken by an owner or holder of debt securities only at the direction of one or
more participants to whose account with the Depository such holder's debt
securities are credited. Additionally, the Depository has advised AMERCO that it
will take such actions with respect to any percentage of the beneficial interest
of holders who hold debt securities through participants only at the direction
of and on behalf of participants whose account holders include undivided
interests that satisfy any such percentage. The Depository may take conflicting
actions with respect to other undivided interests to the extent that such
actions are taken on behalf of participants whose account holders include such
undivided interests.
 
                               SENIOR SECURITIES
 
Payment of the principal of, premium, if any, and interest on senior securities
issued under the Senior Indenture will rank pari passu with all other unsecured
and unsubordinated indebtedness of AMERCO.
 
                            SUBORDINATED SECURITIES
 
Payment of the principal of, premium, if any, and interest on subordinated
securities issued under the Subordinated Indenture will rank pari passu with all
other subordinated indebtedness of AMERCO and will be subordinate and junior in
right of payment, to the extent and in the manner set forth in the Subordinated
Indenture, to all Senior
 
                                       15
<PAGE>   19
 
Indebtedness of AMERCO. The Subordinated Indenture does not contain any
limitation on the amount of Senior Indebtedness than can be incurred by AMERCO.
 
The Subordinated Indenture provides that AMERCO may make no principal, interest
or other payment on account of any subordinated securities or redeem, defease
(other than payments made by the Subordinated Trustee pursuant to the provisions
of the Subordinated Indenture described under "Defeasance") or acquire any of
the subordinated securities for cash, property or securities:
 
       *         upon the maturity of the Designated Senior Indebtedness or any
                 other Senior Indebtedness with an aggregate principal amount in
                 excess of $1,000,000 unless and until all principal, premium
                 and interest on such Senior Indebtedness and all other
                 obligations in respect thereof are first paid in full in cash
                 or cash equivalents or such payment is duly provided for, or
                 unless and until any such maturity by acceleration has been
                 rescinded or waived; or
 
       *         in the event of default in the payment of any principal,
                 premium or interest on or any other amount payable in respect
                 of the Designated Senior Indebtedness or any other Senior
                 Indebtedness with an aggregate principal amount in excess of
                 $1,000,000 when it becomes due and payable, whether at maturity
                 or at a date fixed for prepayment or by declaration or
                 otherwise, unless and until such payment default has been cured
                 or waived or has otherwise ceased to exist.
 
Upon the happening of a default (any event that after notice or passage of time
would be an event of default) or an event of default (any event that permits the
holders of Senior Indebtedness or their representative or representatives
immediately to accelerate its maturity) with respect to any Senior Indebtedness,
other than a default in payment of the principal, premium or interest on such
Senior Indebtedness, and upon written notice of such default or event of default
given to AMERCO and the Subordinated Trustee by the holders of a majority of the
principal amount outstanding of the Designated Senior Indebtedness or their
representative or, at such time there is not Designated Senior Indebtedness, the
holders of a majority of the principal amount outstanding of all Senior
Indebtedness or their representative or representatives or, if such default or
event of default results from the acceleration of the subordinated securities,
immediately upon such acceleration, then, unless such default or event of
default has been cured or waived or otherwise has ceased to exist, AMERCO may
make no payment with respect to any obligation or claim in respect of the
subordinated securities.
 
Notwithstanding the foregoing, unless the Senior Indebtedness in respect of
which such default or event of default exists has been declared due and payable
in its entirety within 180 days after the date written notice of such default or
event of default is delivered as set forth above or the date of such
acceleration as the case may be (the "payment blockage period"), and such
declaration or acceleration has not been rescinded, AMERCO may then pay all sums
not paid to the holders of the subordinated securities during the payment
blockage period due to the foregoing prohibitions and resume all other payments
as and when due on the subordinated securities. Any number of such notices may
be given; provided, however, that (1) during any 360 consecutive days, only one
payment blockage
 
                                       16
<PAGE>   20
 
period may commence and (2) any such default or event of default that existed
upon the commencement of a payment blockage period may not be the basis for the
commencement of any other payment blockage period, unless such default or event
of default shall have been cured or waived for a period of not less than 90
consecutive days.
 
In the event that any payment or distribution of assets of AMERCO from any
source is received by the Subordinated Trustee or the holders on account of any
obligation or claim in respect of the subordinated securities at a time when
such payment or distribution is prohibited by the foregoing provisions, such
payment or distribution will be held in trust for the benefit of the holders of
Senior Indebtedness, and will be paid or delivered by the Subordinated Trustee
or such holders, as the case may be, to the holders of the Senior Indebtedness
remaining unpaid or unprovided for ratably according to the aggregate amounts
remaining unpaid on account of the Senior Indebtedness.
 
The holders of the Senior Indebtedness and their respective representatives are
authorized to demand specific performance of the provisions with respect to
subordination in the Subordinated Indenture at any time when AMERCO or any
holder shall have failed to comply with any provision with respect to
subordination in the Subordinated Indenture applicable to it, and AMERCO and
each holder irrevocably waives any defense based on the adequacy of a remedy at
law that might be asserted as a bar to the remedy of specific performance of
such subordination provision in any action brought therefor by the holders of
the Senior Indebtedness and their respective representatives.
 
By reasons of such subordination, in the event of the liquidation or insolvency
of AMERCO, creditors of AMERCO who are not holders of Senior Indebtedness,
including holders of the subordinated securities, may recover less, ratably,
than holders of Senior Indebtedness.
 
No provision contained in the Subordinated Indenture or the subordinated
securities will affect the obligation of AMERCO, which is absolute and
unconditional, to pay, when due, principal of, premium, if any, and interest on
the subordinated securities. The subordination provisions of the Subordinated
Indenture and the subordinated securities will not prevent the occurrence of any
Event of Default under either of the Indentures or limit the rights of the
Subordinated Trustee or any holder, except as provided in the seven preceding
paragraphs, to pursue any other rights or remedies with respect to the
subordinated securities.
 
                                   COVENANTS
 
The Indentures contain several restrictive covenants. The Indentures do not
contain:
 
       *         any restrictions on AMERCO paying dividends or making other
                 distributions on any of its capital stock or purchasing or
                 redeeming any of its capital stock;
 
       *         any restrictions on AMERCO incurring, assuming or become liable
                 upon senior indebtedness or subordinated indebtedness or any
                 other type of debt securities or other obligations;
 
       *         any restrictions on AMERCO creating liens on its property for
                 any purpose; or
 
                                       17
<PAGE>   21
 
       *         any requirement on AMERCO adhering to any financial ratios or
                 specified levels of net worth or liquidity.
 
Any additional restrictive covenants relating to any series of debt securities
will be described in the prospectus supplement relating to such series. If any
such covenants are described, the prospectus supplement will also state whether
the "covenant defeasance" provisions described below will apply.
 
*         Corporate Existence
 
AMERCO will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and material rights (charter and
statutory) and material franchises of AMERCO; provided, however, that AMERCO
shall not be required to preserve any such right or franchise if our Board of
Directors shall determine that the preservation of such rights and franchises is
no longer desirable in the conduct of the business of AMERCO and our
consolidated subsidiaries considered as a whole, and that the loss thereof is
not disadvantageous in any material respect to the holders of the debt
securities.
 
*         Consolidation, Merger, and Sale of Assets
 
AMERCO, without the consent of any holders of outstanding debt securities, may
consolidate or merge with or into, or transfer or lease its assets as an
entirety to, any corporation, provided that (i) the corporation (if other than
AMERCO) formed by such consolidation or into which AMERCO is merged or that
acquires or leases the assets of AMERCO substantially as an entirety is a
corporation, partnership or trust, is organized and existing under the laws of
any United States jurisdiction and expressly assumes AMERCO's obligations on the
debt securities and under the Indentures, (ii) after giving effect to such
transaction no Event of Default, and no event that, after notice or lapse of
time or both, would become an Event of Default, shall have occurred and be
continuing (provided that a transaction will only be deemed to be in violation
of this condition (ii) as to any series of debt securities as to which such
Event of Default or such event shall have occurred and be continuing), and (iii)
certain other conditions are met.
 
                               EVENTS OF DEFAULT
 
The following are Events of Default under each Indenture with respect to debt
securities of any series issued thereunder:
 
       (1)      failure to pay principal of or premium, if any, on any debt
                security of that series when due;
 
       (2)      failure to pay any interest on any debt security of that series
                when due, continued for 30 days;
 
       (3)      (i) the failure by AMERCO or any of our subsidiaries to pay
                indebtedness for money borrowed (including debt securities of
                other series) in an aggregate principal amount exceeding
                $10,000,000 at the later of final maturity or upon the
                expiration of any applicable period of grace with respect to
                such principal amount or (ii) acceleration of the maturity of
                any indebtedness for money borrowed of AMERCO or any of our
                subsidiaries in
 
                                       18
<PAGE>   22
 
                excess of $10,000,000, if such failure to pay or acceleration is
                not discharged or such acceleration is not annulled within 15
                days after due notice;
 
       (4)      failure to deposit any sinking fund payment, when due, in
                respect of any debt security of that series;
 
       (5)      failure to perform any other covenant or warranty of AMERCO in
                such Indenture (other than a covenant or warranty included in
                such 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 such Indenture;
 
       (6)      certain events in bankruptcy, insolvency or reorganization; and
 
       (7)      any other Event of Default provided with respect to debt
                securities of that series.
 
If an Event of Default specified in clause (6) above occurs and is continuing
with respect to a series of debt securities, then the principal amount of the
outstanding debt securities shall become immediately due and payable without any
declaration or other act on the part of the applicable Trustee or any holder. If
an Event of Default (not specified in clause (6) above) shall occur and be
continuing with respect to outstanding debt securities of any series, either the
applicable Trustee or the holders of at least 25% in principal amount of the
outstanding debt securities of that series may 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 the debt securities of that series to be due and payable
immediately by written notice to AMERCO (and to the applicable Trustee if given
by the holders). At any time after a declaration of acceleration with respect to
debt securities of any series has been made, but before a judgment or decree
based on acceleration has been obtained, the holders of a majority in principal
amount of the outstanding debt securities of that series may, under certain
circumstances, rescind and annul such acceleration. For information as to waiver
of defaults, see "Modification and Waiver" below.
 
Reference is made to the prospectus supplement relating to each series of
Offered Securities that are original issue discount securities for the
particular provisions relating to acceleration of the maturity of a portion of
the principal amount of such original issue discount securities upon the
occurrence of an Event of Default and the continuation thereof.
 
The Indentures provides that each Trustee will be under no obligation, subject
to the duty of the applicable Trustee during default to act with the required
standard of care, to exercise any of its rights or powers under the related
Indenture at the request or direction of any of the holders, unless such holders
shall have offered to the applicable Trustee reasonable indemnity. Subject to
such provisions for indemnification of the applicable Trustee, the holders of a
majority in principal amount of the outstanding debt securities of any series
will have the right to direct the time, method, and place of conducting any
proceeding for any remedy available to that Trustee, or exercising any trust or
power conferred on that Trustee, with respect to the debt securities of that
series.
 
                                       19
<PAGE>   23
 
AMERCO will furnish to each Trustee annually a certificate as to compliance by
AMERCO with all terms, provisions and conditions of the applicable Indenture.
 
                                   DEFEASANCE
 
The prospectus supplement will state if any additional defeasance provision will
apply to the Offered Securities.
 
Defeasance and Discharge
 
Each Indenture provides that, if applicable, AMERCO will be discharged from any
and all obligations in respect of the debt securities of any series issued
thereunder (except for certain obligations to register the transfer or exchange
of debt securities of such series, to replace stolen, lost, or mutilated debt
securities of such series, to maintain paying agencies and to hold monies for
payment in trust) upon the irrevocable deposit with the applicable Trustee, in
trust, of money and/or U.S. Government obligations, which through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of and premium, if
any, and each installment of interest on the debt securities of that series on
the stated maturity of such payments in accordance with the terms of the
applicable Indenture and the debt securities of such series. Such a trust may
only be established if, among other things, AMERCO has delivered to the
applicable Trustee an opinion of counsel (who may be an employee of or counsel
for AMERCO) to the effect that AMERCO has received from, or there has been
published by, the Internal Revenue Service a ruling or there has been a change
in the applicable United States federal income tax law to the effect that
holders of the debt securities of that series will not recognize income, gain,
or loss for federal income tax purposes as a result of such deposit, defeasance,
and discharge and will be subject to federal income tax on the same amount and
in the same manner and at the same times as would have been the case if such
deposit, defeasance, and discharge had not occurred.
 
However, the Statement of Financial Accounting Standards No. 125 "Accounting for
Transfers and Services of Financial Assets and Extinguishments of Liabilities"
as issued by the Financial Accounting Standard's Board will generally not permit
the in-substance defeasance of debt as described above.
 
Defeasance of Certain Covenants and Certain Events of Default
 
Each Indenture provides that AMERCO may omit to comply with the covenants
described under "Covenants," and that may be described in a prospectus
supplement and as set forth in a related Supplemental Indenture, and that
violations of such covenants will not be deemed to be an Event of Default under
the applicable Indenture to the extent that the conditions described herein are
met. Each Indenture also provides with respect to the Offered Securities of any
series issued thereunder, to the extent provided for in the prospectus
supplement, that AMERCO may omit to comply with certain restrictive covenants
provided for in this prospectus or the prospectus supplement and, to the extent
provided in the prospectus supplement, that violations of certain restrictive
covenants provided for in the prospectus supplement shall not be deemed to be an
Event of Default under the applicable Indenture and the debt securities of such
series, upon the deposit with the applicable Trustee, in trust, of money and/or
U.S. Government obligations which
 
                                       20
<PAGE>   24
 
through the payment of interest and principal in respect thereof in accordance
with their terms will provide money in an amount sufficient to pay the principal
of and premium, if any, and each installment of interest on the debt securities
of such series on the stated maturity of such payments in accordance with the
terms of the applicable Indenture and the debt securities of such series. The
obligations of AMERCO under the applicable Indenture and the debt securities of
such series other than with respect to the covenants referred to above and the
Events of Default other than the Event of Default referred to above shall remain
in full force and effect. Such a trust may only be established if, among other
things, AMERCO has delivered to the applicable Trustee an opinion of counsel
(who may be an employee of or counsel for AMERCO) to the effect that the holders
of the debt securities of such series will not recognize income, gain or loss
for federal income tax purposes as a result of such deposit and defeasance of
certain covenants and Events of Default and will be subject to federal income
tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit and defeasance had not occurred.
 
Defeasance and Certain Other Events of Default
 
In the event AMERCO exercises its option to omit compliance with certain
covenants of the applicable Indenture with respect to the Offered Securities of
any series as described above issued thereunder and the Offered Securities of
such series are declared due and payable because of the occurrence of any Event
of Default other than the Event of Default due to certain events in bankruptcy,
insolvency, or reorganization described under "Events of Default," the amount of
money and U.S. Government obligations on deposit with the applicable Trustee
will be sufficient to pay amounts due on the Offered Securities of such series
at the time of their stated maturity but may not be sufficient to pay amounts
due on the Offered Securities of such series at the time of the acceleration
resulting from such Event of Default. However, AMERCO shall remain liable for
such payments.
 
                            MODIFICATION AND WAIVER
 
Modifications and amendments of the Indentures may be made by AMERCO and the
Trustees with the consent of the holders of a majority in principal amount of
the outstanding debt securities of each series affected by such modification or
amendment; provided, however, that no such modification or amendment may,
without the consent of the holder of each outstanding debt security affected
thereby:
 
*         change the stated maturity of the principal of, or any installment of
          principal of or interest on, any debt security;
 
*         reduce the principal amount of, or the premium, if any, or interest,
          if any, on any debt security or any premium payable upon the
          redemption thereof;
 
*         reduce the amount of principal of an original issue discount security
          payable upon acceleration of the maturity thereof;
 
*         adversely affect the rights of such holder under any mandatory
          redemption or repurchase provision or any right or redemption or
          repurchase at the option of such holder;
 
                                       21
<PAGE>   25
 
*         change the place or currency of payment of principal of, or premium,
          if any, or interest, if any, on, any debt security;
 
*         impair the right to institute suit for the enforcement of any payment
          on or with respect to any debt security;
 
*         with respect to the Subordinated Indenture, modify the terms relating
          to subordination in a manner adverse to the holders of debt securities
          issued under such Subordination Indenture; or
 
*         reduce the percentage in principal amount of outstanding debt
          securities of any series, the consent of the holders of which is
          required for modification or amendment of the applicable Indenture or
          for waiver of compliance with certain provisions of the applicable
          Indenture or for waiver of certain defaults.
 
The holders of a majority in principal amount of the outstanding debt securities
of any series may on behalf of the holders of all debt securities of that series
waive, insofar as that series is concerned, compliance by AMERCO with certain
restrictive provisions of the applicable Indenture. The holders of a majority in
principal amount of the outstanding debt securities of any series may on behalf
of the holders of all debt securities of that series waive any past default
under the applicable Indenture with respect to that series, except a default in
the payment of the principal of or premium, if any, or interest on any debt
security of that series or in respect of a provision that under the applicable
Indenture cannot be modified or amended without the consent of the holder of
each outstanding debt security of that series affected.
 
                              CERTAIN DEFINITIONS
 
Set forth below is a summary of certain of the defined terms used in the
covenants contained in the applicable Indenture. Reference is made to the
applicable Indenture for the full definition of all such terms as well as any
other capitalized terms used herein for which no definition is provided.
 
"consolidated subsidiary" means any subsidiary of a person or of any
consolidated subsidiary which is consolidated with such person for financial
reporting purposes in accordance with United States generally accepted
accounting principles.
 
"Designated Senior Indebtedness" means any class of Senior Indebtedness the
aggregate principal amount outstanding of which exceeds $50,000,000 and which is
specifically designated in the instrument evidencing such Senior Indebtedness or
the agreement under which such Senior Indebtedness arises as "Designated Senior
Indebtedness."
 
"indebtedness for money borrowed," when used with respect to AMERCO or any of
our subsidiaries, means any obligation of, or any obligation guaranteed by,
AMERCO or any of our subsidiaries for the repayment of borrowed money, whether
or not evidenced by bonds, debentures, notes or other written instruments, and
any deferred obligation of, or any such obligation guaranteed by, AMERCO for the
payment of the purchase price of property or assets.
 
                                       22
<PAGE>   26
 
"Senior Indebtedness" as defined in the Subordinated Indenture means the

created:
 
       *         for money borrowed by AMERCO;
 
       *         for money borrowed by, or obligations of, others and either
                 assumed or guaranteed, directly or indirectly, by AMERCO;

                 secured by property included in the property, plant and
                 equipment accounts of AMERCO at the time of the acquisition of
                 such property by AMERCO, for the payment of which AMERCO is
                 directly liable;
 
and (b) all deferrals, renewals, extensions and refunding of, and amendments,

subordinated to other indebtedness of AMERCO. Notwithstanding anything to the
contrary in the Subordinated Indenture or the subordinated securities, Senior
Indebtedness shall not include (1) any indebtedness of AMERCO which, by its

                                 GOVERNING LAW
 
The Indentures and the Offered Securities will be governed by and construed in
accordance with the laws of the State of New York.
 
                                       23
<PAGE>   27
 
                              PLAN OF DISTRIBUTION
 
We may sell the Offered Securities:
 
       *         through agents;
 
       *         through underwriters or dealers;
 
       *         directly to one or more purchasers; or
 
       *         through some combination of these methods.
 
By Agents
 
The Offered Securities may be sold through agents we designate. Except as
otherwise set forth in a prospectus supplement, the agents will agree to use
their reasonable best efforts to solicit purchases for the period of their
appointment.
 
By Underwriters
 
If underwriters are used in the sale, the underwriters will acquire the Offered
Securities for their own account. The underwriters may resell the Offered
Securities in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The obligations of the underwriters to purchase the Offered Securities will be
subject to certain conditions. The underwriters will be obligated to purchase
all the Offered Securities of the series offered if any of the Offered
Securities are purchased. Any public offering price and any discounts or
concessions allowed or re-allowed or paid to dealers may be changed from time to
time.
 
By Dealers
 
If dealers are used in the sale, we will sell the Offered Securities to the
dealers, as principal. The dealers may then resell the Offered Securities to the
public at varying prices to be determined by them at the time of sale.
 
Direct Sales
 
We may also directly sell the Offered Securities. In this case, no underwriters,
dealers or agents would be involved.
 
General Information
 
Any underwriter, dealer or agent involved in the offer and sale of the Offered
Securities will be named in the applicable prospectus supplement. Underwriters,
dealers and agents that participate in the distribution of the Offered
Securities may be deemed underwriters under the Securities Act of 1933, and any
discounts or commissions they receive from us or commissions from purchasers of
the Offered Securities may be treated as underwriting discounts, concessions or
commissions under the Securities Act. Any underwriter, dealer or agent will be
identified and their compensation described in the applicable prospectus
supplement.
 
                                       24
<PAGE>   28
 
We may have agreements with the underwriters, dealers and agents to indemnify
them against certain civil liabilities, including liabilities under the
Securities Act, or to contribute to payments that the underwriters, dealers or
agents may be required to make.
 
Certain of the underwriters or agents and their affiliates may be customers of,
engage in transactions with and perform investment banking, commercial banking
and other financial services for AMERCO and our affiliates in the ordinary
course of business.
 
Each series of Offered Securities will be a new issue with no established
trading market. We do not intend to list any of the Offered Securities on a
national securities exchange or quotation system. It is possible that one or
more underwriters or broker-dealers may make a market in the Offered Securities,
but will not be obligated to do so and may discontinue any market making at any
time without notice. Therefore, we can give you no assurance as to the existence
or liquidity of a trading market for any of the Offered Securities.
 
In connection with an offering of our Offered Securities, underwriters, dealers
or agents may purchase and sell them in the open market. These transactions may
include stabilizing transactions and purchases to cover syndicate short
positions created in connection with the offering. Stabilizing transactions
consist of certain bids or purchases for the purpose of preventing or slowing a
decline in the market price of the Offered Securities; and syndicate short
positions involve the sale by the underwriters, dealers or agents, as the case
may be, of a greater number of Offered Securities than they are required to
purchase from us in the offering. Underwriters also may impose a penalty bid,
which means that the underwriting syndicate may reclaim selling concessions
allowed to syndicate members or other broker dealers who sell Offered Securities
in the offering for their account if the syndicate repurchases the securities in

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
The Nevada General Corporation Law requires AMERCO to indemnify officers and
directors for any expenses incurred by any officer or director in connection
with any actions or proceedings, whether civil, criminal, administrative, or
investigative, brought against such officer or director because of his or her
status as an officer or director, to the extent that the director or officer has
been successful on the merits or otherwise in defense of the action or
proceeding. The Nevada General Corporation Law permits a corporation to
indemnify an officer or director, even in the absence of an agreement to do so,
for expenses incurred in connection with any action or proceeding if such
officer or director acted in good faith and in a manner in which he or she
reasonably believed to be in or not opposed to the best interests of the
corporation and such indemnification is authorized by the stockholders, by a
quorum of disinterested directors, by independent legal counsel in a written
opinion authorized by a majority vote of a quorum of directors consisting of
disinterested directors, or by independent legal counsel in a written opinion if
a quorum of disinterested directors cannot be obtained. AMERCO's Restated
Articles of Incorporation eliminate personal liability of directors and
officers, to AMERCO or its stockholders, for damages for breach of their
fiduciary duties as directors or officers, except for liability (i) for acts or
omissions that involve intentional misconduct, fraud, or a knowing violation of
law, or (ii) for the unlawful payment of dividends. In addition, AMERCO's Bylaws
provide that AMERCO shall indemnify, to the fullest extent authorized or
permitted by law, any person made, or threatened to be made, a defendant in any
threatened, pending, or completed action, suit, or proceeding by reason of the
fact that he or she was a director or officer of AMERCO. AMERCO has also
executed Indemnification Agreements that provide that certain of AMERCO's
directors and officers shall be indemnified and held harmless by AMERCO to the
fullest extent permitted by applicable law or the Restated Articles of
incorporation or Bylaws of AMERCO. AMERCO has established a trust fund with
Harris Trust and Savings Bank as trustee in order to fund its obligations under
the Indemnification Agreements. AMERCO has agreed to maintain a minimum balance
in the trust fund of $1,000,000. The Nevada General Corporation Law prohibits
indemnification of a director or officer if a final adjudication establishes
that the officer's or director's acts or omissions involved intentional
misconduct, fraud, or a knowing violation of the law and
<PAGE>   31
 
were material to the cause of action. Despite the foregoing limitations on
indemnification, the Nevada General Corporation Law may permit an officer or
director to apply to the court for approval of indemnification even if the
officer or director is adjudged to have committed intentional misconduct, fraud,
or a knowing violation of the law. The Nevada General Corporation Law also
provides that indemnification of directors is not permitted for the unlawful
payment of distributions, except for those directors registering their dissent
to the payment of the distribution.

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 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.
 
(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
<PAGE>   32
 
         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.
 
(4)      That, for purposes of determining any liability under the Securities
         Act of 1933, each such filing of the registrant's annual report
         pursuant to Section 13(a) or 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.
 
(5)      That, 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.
 
(6)      That, for the purpose of determining any liability under the Securities
         Act of 1933, each post-effective amendment that contains a form of
         prospectus shall be deemed to be a new registration statement relating
         to the securities offered therein, and the offering of such securities
         at that time shall be deemed to be the initial bona fide offering
         thereof.
 
(7)      To file an application for the purpose of determining the eligibility
         of the Trustee to act under subsection (a) of Section 310 of the Trust
         Indenture Act of 1939 in accordance with the rules and regulations
         prescribed by the Commission under Section 305(b)(2) of the Trust
         Indenture Act of 1939.
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 15 above, or otherwise,
the registrant 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 a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant 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 registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

all such matters be certified by, or covered by the opinion of, only one such

or representations by, counsel, unless such officer knows, or in the exercise of

it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the

substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such

<PAGE>   18
individual signing such instrument or writing acknowledged to him the execution
thereof. Where such execution is by a signer acting in a capacity other than his
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority. The fact and date of the execution of any
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

                  (c) The Company may, in the circumstances permitted by the
Trust Indenture Act, fix any day as the record date for the purpose of
determining the Holders of Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action, or to vote on any action, authorized or permitted to be given or taken
by Holders of Securities of such series. If not set by the Company prior to the
first solicitation of a Holder of Securities of such series made by any Person
in respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be. With regard to any record date for action to be taken by the Holders of
one or more series of Securities, only the Holders of Securities of such series
on such date (or their duly designated proxies) shall be entitled to give or
take, or vote on, the relevant action.

                  (d) The ownership of Securities shall be proved by the
Security Register.

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

                           (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 (whether in its original or
                  facsimile form) to or with the Trustee at its office, 101
                  Barclay Street, Floor 21 West, New York, New York, 10286 ,
                  Attention: Michele Russo, or at such other address as
                  furnished in writing to the Company by the Trustee, or

                           (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 and mailed,
                  first-class postage prepaid, to the Company addressed to it at
                  the

<PAGE>   19
                  address of its principal office specified in the first

                  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.

part of and govern this Indenture, the Trust Indenture Act provision shall
control. If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or excluded,
as the case may be.

impaired thereby.

                  In any case where any Interest Payment Date, Redemption Date

Payment, then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of the Securities of any series 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, provided
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

                  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 in registered
form without coupons in such denominations as shall be specified as contemplated
by Section 301. In the absence of any such provisions 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 (whether in its original or
facsimilie form) reproduced thereon attested by its Treasurer, one of its
Assistant Treasurers, 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.


                                       22
<PAGE>   31
                  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 in or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in 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

                  (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 time
of 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


                                       23
<PAGE>   32
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 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
a like aggregate principal amount and tenor. 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.

                  Upon surrender for registration of transfer of any Security of
any series at the office or agency 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 a like aggregate
principal amount and tenor.


                                       24
<PAGE>   33
                  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 a like aggregate principal amount and tenor, 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.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
1103 and ending at the close of business on the day of such mailing, or (ii) 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.

                  Notwithstanding the foregoing, no Book-Entry Security shall be
registered for transfer or exchange, or authenticated and delivered, whether
pursuant to this Section, Sections 304, 306, 906 or 1107 or otherwise, in the
name of a Person other than the Depository for such Book-Entry Security or its
nominee until (i) the Depository with respect to a Book-Entry Security notifies
the Company that it is unwilling or unable to continue as Depository for such
Book-Entry Security or the Depository ceases to be a clearing agency registered
under the Exchange Act at a time when such Depository is required to be so
registered in order to act as Depository, (ii) the Company executes and delivers
to the Trustee a Company Order that such Book-Entry Security shall be so
transferable and exchangeable or (iii) there shall have occurred and be
continuing an Event of Default with respect to the Securities of such series.
Upon the occurrence in respect of any Book-Entry Security of any series of any
one or more of the conditions specified in clauses (i), (ii) or (iii) of the
preceding sentence or such other conditions as may be specified as contemplated
by Section 301 for such series, such Book-Entry Security may be registered for


                                       25
<PAGE>   34
transfer or exchange for Securities registered in the names of, or authenticated
and delivered to, such Persons as the Depository with respect to such series
shall direct.

                  Except as provided in the preceding paragraph, any Security
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, any Book-Entry Security, whether pursuant to this Section,
Section 304, 306, 906 or 1107 or otherwise, shall also be a Book-Entry Security
and bear the legend specified in Section 204.

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.

                  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 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 provided in this
clause. Thereupon the Trustee shall fix a Special Record Date for the payment of
such Defaulted Interest which shall not be more than 15 days and not less than
10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Securities of such series
at his address as it appears in the Security Register, not less than 10 days
prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been 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 pay 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.


                                       27
<PAGE>   36
                  Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 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.

                  Notwithstanding the foregoing, with respect to any Book-Entry
Security, nothing herein shall prevent the Company, the Trustee, or any agent of
the Company or the Trustee, from giving effect to any written certification,
proxy or other authorization furnished by a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depository as Holder of such Book-Entry Security.

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 cancelled 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
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 cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of by
the Trustee in its customary manner.

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.

SECTION 311.               Book-Entry System.


                                       28
<PAGE>   37
                  The Securities shall be represented by one or more permanent
global notes (each, a "Global Security") deposited with, or on behalf of, The
Depositary Trust Company, as Depository under the Indenture (the "Depository"),
and registered in the name of the Depository's nominee. Except as set forth in
the following paragraph, (1) owners of beneficial interests in a Global Security
shall not be entitled to have Securities represented by such Global Securities
registered in their names, will not receive or be entitled to receive physical
delivery of Securities in definitive form and shall not be considered the owners
or Holders thereof under the Indenture and (2) each Global Security may be
transferred, in whole and not in part, only to another nominee of the Depository
or to a successor of the Depository or its nominee. Accordingly, beneficial
interests in the Securities shall be shown on, and transfers thereof shall be
effected only through, records maintained by the Depository and its
participants.

                  Notwithstanding any provisions of Section 305 hereof, no
Security that is a Global Security shall be registered for transfer or exchange,
or be authenticated and delivered, and owners of beneficial interests in any
Global Security will not be entitled to receive Securities in definitive form
and will not be considered Holders of Securities unless (1) the Depository
notifies the Company that it is unwilling or unable to continue as Depository
for such Global Security or if at any time the Depository ceases to be a
clearing agency registered under the Exchange Act, (2) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (3) there shall have occurred and be continuing a Default or an
Event of Default. In such circumstances, upon surrender by the Depository or a
successor depository of any Global Security, Securities in definitive form will
be issued to each Person that the Depository or successor depository identifies
as the beneficial owner of the related Securities. Upon such issuance, the
Trustee is required to register such Securities in the name of, and cause such
Securities to be delivered to, such Person or Persons (or nominees thereof).
Such Securities would be issued in fully registered form without coupons, in
denominations of $1,000 and integral multiples thereof.

                  The Depository shall be permitted to take any action permitted
to be taken by an owner or Holder of Securities only at the direction of one or
more participants in the Depository, as it may from time to time determine.

                  Principal and interest payments on Securities registered in
the name of or held by the Depository or its nominee shall be made to the
Depository or its nominees, as the case may be, as the registered owner of the
Global Security representing such Securities. The Company and the Trustee shall
treat the Persons in whose name the Securities are registered as the Holders of
such Securities for the purpose of receiving payment of principal and interest
on such Securities and for all other purposes whatsoever. Therefore, none of the
Company, the Trustee or any Paying Agent has direct responsibility or liability
for the payment of principal and interest on the Securities to owners of
beneficial interests in any Global Security. Payments by direct and indirect
participants in the Depository shall be the responsibility of such participants.

<PAGE>   38
                  The Securities shall trade in the Depository's Same-Day Funds
Settlement System until Maturity (or until they are subject to acceleration
pursuant to Article Five hereof), and secondary market trading activity in the
Securities may be required by the Depository to settle in immediately available
funds.

SECTION 312.               CUSIP Numbers.

                  The Company in issuing the Securities may use "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

                           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

                  (1)      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

to time upon Company Request any money or U.S. Government Obligations held by it
as provided in Section 403 or 1005 which, in the opinion of a nationally

specifically pledged as security for, and dedicated solely to, the benefit of
the Holders of the Securities of that series, with reference to this Section
403, (A) money in an amount, or (B) U.S. Government Obligations which through

the same times, as would have been the case if such deposit, defeasance and
discharge had not occurred; and

                  (5) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions

default in whose performance or whose breach is elsewhere in this Section
specifically dealt with or which has expressly been included in this Indenture

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

or order for relief or any such other decree or order unstated and in effect for
a period of 60 consecutive days; or

                  (6) the commencement by the Company of a voluntary case or

at the later of final maturity thereof or upon the expiration of any applicable
period of grace with respect to such principal amount or (ii) in such Debt in an
aggregate principal amount


                                       34
<PAGE>   43
exceeding $10,000,000 becoming or being declared due and payable prior to the
date on which it would otherwise have become due and payable without such Debt
having been discharged, or such acceleration having been rescinded or annulled,
within a period of 15 days after there shall have 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 Securities, a written
notice specifying such default and requiring the Company to cause such Debt to
be discharged or to cause such acceleration to be rescinded or annulled and
stating that such notice is a "Notice of Default" hereunder; provided, however,
that the Trustee shall not be deemed to have knowledge of such default unless
either (A) an officer in the Corporate Trust Administration of the Trustee shall
have actual knowledge of such default or (B) the Trustee shall have received
written notice thereof from the Company, from any Holder, from the holder of any
such Debt or from the trustee under any such mortgage, indenture or other
instrument; or

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

                  Upon receipt by the Trustee of any Notice of Default pursuant
to this Section 501 with respect to Securities of a series all or part of which
is represented by a Book-Entry Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such Notice of Default, which record date shall be at the close of business on
the day the Trustee receives such Notice of Default. The Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to join in such Notice of Default, whether or not such Holders remain Holders
after such record date; provided, that unless Holders of at least 10% in
principal amount of the Outstanding Securities of such series, or their proxies,
shall have joined in such Notice of Default prior to the day which is 90 days
after such record date, such Notice of Default shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new Notice of Default which is
identical to a Notice of Default which has been canceled pursuant to the proviso
to the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 501.

SECTION 502.               Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default 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 (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series 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, except that no such
declaration shall be required upon the occurrence of an Event of Default
specified in Section 501(5) or 501(6).


                                       35
<PAGE>   44
                  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 and premium, if any, of
Securities of that series which have 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.

                  Upon receipt by the Trustee of any written notice declaring
such an acceleration, or recision and annulment thereof, with respect to
Securities of a series all or part of which is represented by a Book-Entry
Security, a record date shall be established for determining Holders of
Outstanding Securities of such series entitled to join in such notice, which
record date shall be at the close of business on the day the Trustee receives
such notice. The Holders on such record date, or their duly designated proxies,
and only such Persons, shall be entitled to join in such notice, whether or not
such Holders remain Holders after such record date; provided, that unless such
declaration of acceleration, or rescission and annulment, as the case may be,
shall have become effective by virtue of the requisite percentage having joined
in such notice prior to the day which is 90 days after such record date, such
declaration of acceleration, or rescission and annulment, as the case may be,
shall automatically and without further action by any Holder be canceled and of
no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy
of a Holder, from giving, after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission or annulment thereof, as
the case may be, which has been canceled


                                       36
<PAGE>   45
pursuant to the proviso to the preceding sentence, in which event a new record
date shall be established pursuant to the provisions of this Section 502.

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, 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 the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon such Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such
Securities, wherever situated.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series 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 Proofs 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


                                       37
<PAGE>   46
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.

                  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.

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; and

                  SECOND: To the payment of the amounts then due and unpaid for
principal of 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.

                  THIRD: 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:


                                       38
<PAGE>   47
                  (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;

                  (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, 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) any interest on such Security on the Stated Maturity or
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.


                                       39
<PAGE>   48
                  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 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, and

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

                  Upon receipt by the Trustee of any written notice directing
the time, method or place of conducting any such proceeding or exercising any
such trust or power, with respect to Securities of a series all or part of which
is represented by a Book-Entry Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that unless Holders of a majority in principal amount of the
Outstanding Securities of such series shall have joined in such notice prior to
the day which is 90 days after such record date, such notice shall automatically
and without further action by any Holder be canceled and of no further effect.
Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, after expiration of such 90-day period, a new notice identical


                                       40
<PAGE>   49
to a notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 512.

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 which under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to waive any past
default hereunder. If a record date is fixed, the Holders on such record date,
or their duly designated proxies, and only such Persons, shall be entitled to
waive any default hereunder, whether or not such Holders remain Holders after
such record date; provided, that unless such majority in principal amount shall
have been obtained prior to the date which is 90 days after such record date,
any such waiver previously given shall automatically and without further action
by any Holder be canceled and of no further effect.

                  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 (including reasonable attorneys' fees and expenses) against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act.

SECTION 515.               Waiver of 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 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


                                       41
<PAGE>   50
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 and this Indenture. 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, upon receipt by a Responsible Officer of such notice of
default, 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(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or 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 conclusively rely and shall be fully
protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or
document (whether in its original or facsimile form) believed by it to be
genuine and to have been signed or presented by the proper party or parties;


                                       42
<PAGE>   51
                  (2) any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution;

                  (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 of its own selection
and the 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 at the expense of the Company and shall incur no liability or
additional liability of any kind by reason of such inquiry or investigation of
Trustee;

                  (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; and

                  (8) the rights, privileges and benefits (including right to
indemnity) of trustee are extended to and shall be enforceable by the trustee in
each of its capacities hereunder and each agent employed to act hereunder.

SECTION 604.               Not Responsible for Recitals or Issuance of
                           Securities.

                  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 the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no


                                       43
<PAGE>   52
representations as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee or any Authenticating Agent shall not be accountable for
the use or application by the Company of Securities or the process 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 such compensation
as shall be agreed upon from time to time in writing 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 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 willful misconduct; and

                  (3) to fully indemnify the Trustee and any predecessor Trustee
for, and to hold it harmless against, any and all loss, claim, damage, liability
or expense (including taxes other than taxes based on the income of the Trustee)
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.

<PAGE>   53
SECTION 608.               Disqualification; 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.

SECTION 609.               Corporate Trustee Required; Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
a Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $50,000,000. If such Person
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 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 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.

                  (1) 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.

                  (2) 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, at
the expense of the Company, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

                  (3) 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.

                  (4) If at any time:

                           (a) 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

                           (b) 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


                                       45
<PAGE>   54
                           (c) 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, (i) the Company by a Board
Resolution may remove the Trustee with respect to all Securities, or (ii)
subject to Section 514, any Holder who has been a 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.

                  (5) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, with respect to the Securities of one or more series, the Company, by
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.

                  (6) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
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.

                  (1) 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


                                       46
<PAGE>   55
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.

                  (2) 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 deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (a) 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, (b) 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 (c) 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.

                  (3) 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 paragraph (2) and (3) of this Section, as the case may be.

                  (4) 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.


                                       47
<PAGE>   56
                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. 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 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 corporation 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 corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion


                                       48
<PAGE>   57
or consolidation to which such Authenticating Agent shall be a party, or any
corporation succeeding to the corporate agency or corporate trust business of an
Authenticating Agent, shall continue to be an Authenticating Agent, provided
such corporation 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 mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder

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

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such
record date or their duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental indenture, whether or not such Holders
remain Holders after such record date; provided, that unless such consent shall
have become effective by virtue of the requisite percentage having been obtained
prior to the date which is 90 days after such record date, any such consent
previously given shall automatically and without further action by any Holder be
canceled and of no further effect.

                  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.

                  In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trusts 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 of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

SECTION 905.               Conformity with Trust Indenture Act.

                  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


                                       55
<PAGE>   64
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.


                                   ARTICLE TEN
                                    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 of that series and this Indenture.

SECTION 1002.              Maintenance of Office or Agency.

                  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 or exchange 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.


                                       56
<PAGE>   65
                  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 (i) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) 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, and 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.

                  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.

SECTION 1004.              Corporate Existence.

                  The Company shall do or cause to be done all things necessary
to preserve and keep in full force and effect its corporate existence and
material rights (charter and statutory) and material franchises of the Company;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors of the Company shall determine


                                       57
<PAGE>   66
that the preservation of such rights and franchises is no longer desirable in
the conduct of the business of the Company and its Consolidated Subsidiaries
considered as a whole, and that the loss thereof is not disadvantageous in any
material respect to the Holders of the Securities.

SECTION 1005.              Defeasance of Certain Obligations.

                  If this Section 1005 is specified, as contemplated by Section
301, to be applicable to Securities of any series, (i) the Company may omit to
comply with any term, provision or condition of those certain covenants
established pursuant to Sections 301 and 1004 hereof and to which this Section
1005 is to be made applicable, and (ii) Section 501(4) with respect to such
covenants to which this Section 1005 is to be made applicable shall be deemed
not to be an Event of Default, in each case with respect to the Securities of
that series, provided that the following conditions have been satisfied:

                  (1) With reference to this Section 1005, the Company has
deposited or caused to be deposited with the Trustee (or another trustee
satisfying the requirements of Section 609) irrevocably (irrespective of whether
the conditions in subparagraphs (2), (3), (4), (5) and (6) below have been
satisfied, but subject to the provisions of Section 402(3) and the last
paragraph of Section 1003), as trust funds in trust, specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of the
Securities of that series, (A) money in an amount, or (B) U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide not later than the opening
of business on the due date of any payment referred to in clause (i) or (ii) of
this subparagraph (1) money in an amount, or (C) a combination thereof,
sufficient, in the opinion of a nationally recognized firm of independent
certified public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge (i) the principal (and premium,
if any) and each installment of principal (and premium, if any) and interest on
the Outstanding Securities of that series on the Stated Maturity of such
principal or installment of principal or interest and (ii) any mandatory sinking
fund payments or analogous payments applicable to Securities of such series on
the day on which such payments are due and payable in accordance with the terms
of this Indenture and of such Securities;

                  (2) Such deposit shall not cause the Trustee with respect to
the Securities of that series to have a conflicting interest for purposes of the
Trust Indenture Act with respect to the Securities of any series;

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

                  (4) No Event of Default or event which with the giving of
notice or lapse of time, or both, would become an Event of Default with respect
to the Securities of that series shall have occurred and be continuing on the
date of such deposit and no Event of Default under Section


                                       58

501(5) or Section 501(6) or event which with the giving of notice or lapse of
time, or both, would become an Event of Default under Section 501(5) or Section
501(6) shall have occurred and be continuing on the 91st day after such date;

                  (5) The Company has delivered to the Trustee an Opinion of
Counsel to the effect that Holders of the Securities of such series will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance of certain obligations and will be subject to
federal income tax on the same amount and in the same manner and at the same
times, as would have been the case if such deposit and defeasance had not
occurred; and

                  (6) 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 defeasance contemplated by this
Section have been complied with.

SECTION 1006.              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.


                  The Company shall deliver to the Trustee, as soon as possible
and in any event within five days after the Company becomes aware of the
occurrence of any Event of Default or an event which, with notice or the lapse
of time or both, would constitute an Event of Default, an Officers' Certificate
setting forth the details of such Event of Default or default and the action
which the Company proposes to take with respect thereto.


SECTION 1007.              Waiver of Certain Covenants.

                  The Company may omit in any particular instance to comply with
any term, provision or condition of those certain covenants contained herein or
established pursuant to Section 301 hereof to which this Section 1007 is said to
be applicable, with respect to the Securities of any series if before the time
for such compliance the Holders of at least a majority in principal amount of
the Outstanding Securities of such series 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.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to waive any such term,
provision or condition. If a record date is fixed, the Holders on such record
date or their duly designated proxies, and only such Persons, shall be entitled
to waive any such term, provision or condition hereunder, whether or not such
Holders remain Holders after such record date; provided, that unless the Holders
of at least a majority in principal amount of the Outstanding Securities of such
series shall have waived such term, provision or condition prior to the date
which is 90 days after such record date, any such


                                       59
<PAGE>   68
waiver previously given shall automatically and without further action by any
Holder be canceled and of not further effect.

SECTION 1008.              Calculation of Original Issue Discount.

                  The Company shall file with the Trustee promptly at the end of
each calendar year (I) a written notice specifying the amount of the original
issue discount (including daily rates and accrual periods) accrued on
Outstanding Securities as of the end of such year and (ii) such other specific
information relating to such original issue discount as may then be relevant
under the Internal Revenue Code of 1986, as amended from time to time.


                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

SECTION 1101.              Applicability of Article.

                  Securities of any series which are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 301 for Securities of any
series) in accordance with this Article.

SECTION 1102.              Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or by action taken pursuant to a Board
Resolution. In case of any redemption at the election of the Company of less
than all the Securities of any series, 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
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

SECTION 1103.              Selection by Trustee of Securities to Be Redeemed.

                  If less than all the Securities of any series are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate (but subject to compliance with
the rules of any Securities Exchange on which the Securities of such series may
be listed) and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities of that series or
any integral multiple thereof)


                                       60
<PAGE>   69
of the principal amount of Securities of such series of a denomination larger
than the minimum authorized denomination for Securities of that series; provided
that if less than all the Securities of a series having different tenor are to
be redeemed, the specific Securities to be redeemed shall be selected by the
Company. If less than all of the Securities of such series and of a specified
tenor are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series and specified tenor not previously
called for redemption in accordance with the preceding sentence.

                  The Trustee shall promptly notify the Company (or, in the case
of a selection by the Company, the Company shall promptly notify the Trustee) in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in
part, to the portion of the principal 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
are to be redeemed, the identification (and, in the case of partial redemption
of any Securities, the principal amounts) of the particular Securities 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 such Securities are to be
surrendered for payment of the Redemption Price,

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


                                       61
<PAGE>   70
                  (7) the CUSIP numbers, if any, of the Securities to be
redeemed.

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

SECTION 1105.              Deposit of Redemption Price.

                  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.

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 shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the 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. If a Book-Entry Security is so
surrendered, such new Security so issued shall be a new Book-Entry Security.

                                  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 a series except as otherwise
specified as contemplated by Section 301 for Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment". If provided for by the terms of Securities of
any series, 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 of any series as provided for by the
terms of Securities of such series.

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 the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities 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 60 days prior to each sinking fund payment date
for any series of Securities, the Company will deliver to the Trustee an
Officers' Certificate specifying the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, 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
of that series pursuant to Section 1202 and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 and not more than 60 days before
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


                                       63
<PAGE>   72
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                  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.

a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved

vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be. With regard to any record date for action to be taken by the Holders of
one or more series of Securities, only the Holders of Securities of such series

take, or vote on, the relevant action.

                  Barclay Street, Floor 21 West, New York, New York, 10286 ,
                  Attention: Michele Russo, or at such other address as

                           (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 and mailed,
                  first-class postage prepaid, to the Company addressed to it at
                  the address of its principal office specified in the first

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

                  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 effected or
impaired thereby.

set forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same.

                  No service charge shall be made for any such registration of

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

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 in registered

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 Treasurer, one of its Assistant Treasurers, its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.


                                       23
<PAGE>   33
                  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 in or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in 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

                  (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 time
of 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.


                                       24
<PAGE>   34
         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 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
a like aggregate principal amount and tenor. 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

                                       25
<PAGE>   35
Trustee is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of securities as herein provided.

                  Upon surrender for registration of transfer of any Security of
any series at the office or agency 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 a like aggregate
principal amount and tenor.

                  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 a like aggregate principal amount and tenor, 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.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
1103 and ending at the close of business on the day of such mailing, or (ii) 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.

                  Notwithstanding the foregoing, no Book-Entry Security shall be
registered for transfer or exchange, or authenticated and delivered, whether
pursuant to this Section, Sections 304, 306, 906 or 1107 or otherwise, in the
name of a Person other than the Depository for

                                       26
<PAGE>   36
such Book-Entry Security or its nominee until (i) the Depository with respect to
a Book-Entry Security notifies the Company that it is unwilling or unable to
continue as Depository for such Book-Entry Security or the Depository ceases to
be a clearing agency registered under the Exchange Act at a time when such
Depository is required to be so registered in order to act as Depository, (ii)
the Company executes and delivers to the Trustee a Company Order that such
Book-Entry Security shall be so transferable and exchangeable or (iii) there
shall have occurred and be continuing an Event of Default with respect to the
Securities of such series. Upon the occurrence in respect of any Book-Entry
Security of any series of any one or more of the conditions specified in clauses
(i), (ii) or (iii) of the preceding sentence or such other conditions as may be
specified as contemplated by Section 301 for such series, such Book-Entry
Security may be registered for transfer or exchange for Securities registered in
the names of, or authenticated and delivered to, such Persons as the Depository
with respect to such series shall direct.

                  Except as provided in the preceding paragraph, any Security
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, any Book-Entry Security, whether pursuant to this Section,
Section 304, 306, 906 or 1107 or otherwise, shall also be a Book-Entry Security
and bear the legend specified in Section 204.

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.

                  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 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.

                                       27
<PAGE>   37
                  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 provided in this
clause. Thereupon the Trustee shall fix a Special Record Date for the payment of
such Defaulted Interest which shall not be more than 15 days and not less than
10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Securities of such series
at his address as it appears in the Security Register, not less than 10 days
prior to such Special Record Date. Notice of the proposed payment of such
Defaulted

                                       28
<PAGE>   38
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 pay 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.

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.

                  Notwithstanding the foregoing, with respect to any Book-Entry
Security, nothing herein shall prevent the Company, the Trustee, or any agent of
the Company or the Trustee, from giving effect to any written certification,
proxy or other authorization furnished by a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depository as Holder of such Book-Entry Security.

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 cancelled 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
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 cancelled by the Trustee. No

                                       29
<PAGE>   39
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of by
the Trustee in its customary manner.

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.

SECTION 311. Book-Entry System.

                  The Securities shall be represented by one or more permanent
global notes (each, a "Global Security") deposited with, or on behalf of, The
Depositary Trust Company, as Depository under the Indenture (the "Depository"),
and registered in the name of the Depository's nominee. Except as set forth in
the following paragraph, (1) owners of beneficial interests in a Global Security
shall not be entitled to have Securities represented by such Global Securities
registered in their names, will not receive or be entitled to receive physical
delivery of Securities in definitive form and shall not be considered the owners
or Holders thereof under the Indenture and (2) each Global Security may be
transferred, in whole and not in part, only to another nominee of the Depository
or to a successor of the Depository or its nominee. Accordingly, beneficial
interests in the Securities shall be shown on, and transfers thereof shall be
effected only through, records maintained by the Depository and its
participants.

                  Notwithstanding any provisions of Section 305 hereof, no
Security that is a Global Security shall be registered for transfer or exchange,
or be authenticated and delivered, and owners of beneficial interests in any
Global Security will not be entitled to receive Securities in definitive form
and will not be considered Holders of Securities unless (1) the Depository
notifies the Company that it is unwilling or unable to continue as Depository
for such Global Security or if at any time the Depository ceases to be a
clearing agency registered under the Exchange Act, (2) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (3) there shall have occurred and be continuing a Default or an
Event of Default. In such circumstances, upon surrender by the Depository or a
successor depository of any Global Security, Securities in definitive form will
be issued to each Person that the Depository or successor depository identifies
as the beneficial owner of the related Securities. Upon such issuance, the
Trustee is required to register such Securities in the name of, and cause such
Securities to be delivered to, such Person or Persons (or nominees thereof).
Such Securities would be issued in fully registered form without coupons, in
denominations of $1,000 and integral multiples thereof.

                  The Depository shall be permitted to take any action permitted
to be taken by an owner or Holder of Securities only at the direction of one or
more participants in the Depository, as it may from time to time determine.

                                       30
<PAGE>   40
                  Principal and interest payments on Securities registered in
the name of or held by the Depository or its nominee shall be made to the
Depository or its nominees, as the case may be, as the registered owner of the
Global Security representing such Securities. The Company and the Trustee shall
treat the Persons in whose name the Securities are registered as the Holders of
such Securities for the purpose of receiving payment of principal and interest
on such Securities and for all other purposes whatsoever. Therefore, none of the
Company, the Trustee or any Paying Agent has direct responsibility or liability
for the payment of principal and interest on the Securities to owners of
beneficial interests in any Global Security. Payments by direct and indirect
participants in the Depository shall be the responsibility of such participants.

                  The Securities shall trade in the Depository's Same-Day Funds
Settlement System until Maturity (or until they are subject to acceleration
pursuant to Article Five hereof), and secondary market trading activity in the
Securities may be required by the Depository to settle in immediately available
funds.

SECTION 312. CUSIP Numbers.

                  The Company in issuing the Securities may use "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify

satisfaction and discharge.

SECTION 402. Application of Trust Money.

                  (1) Subject to the provisions of the last paragraph of Section
1003, all money deposited with the Trustee pursuant to Section 401, all money

to time upon Company Request any money or U.S. Government Obligations held by it
as provided in Section 403 or 1005 which, in the opinion of a nationally

specifically dealt with or which has expressly been included in this Indenture

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

                  (5) the entry by a court having jurisdiction in the premises

Company 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 unstated and in effect for
a period of 60 consecutive days; or

                  (6) 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 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 or other similar official of the Company or of

                  (7) default (including a default with respect to debt
securities of any series other than the Securities) under any Debt of the
Company or any Subsidiary thereof, which default shall have resulted (i) in a
failure to pay an aggregate principal amount exceeding $10,000,000 of such Debt
at the later of final maturity thereof or upon the expiration of any applicable
period of grace with respect to such principal amount or (ii) in such Debt in an
aggregate principal amount exceeding $10,000,000 becoming or being declared due
and payable prior to the date on which it would otherwise have become due and
payable without such Debt having been discharged, or such acceleration having
been rescinded or annulled, within a period of 15 days after there shall have
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 Securities, a written notice specifying such default and requiring the
Company to cause such Debt to be discharged or to cause such acceleration to be
rescinded or annulled and stating that such notice is a "Notice of Default"
hereunder; provided, however, that the Trustee shall not be deemed to have
knowledge of such default unless either (A) an officer in the Corporate Trust
Administration of the Trustee shall have actual knowledge of such default or (B)
the Trustee shall have received written notice thereof from the Company, from
any Holder, from the holder of any such Debt or from the trustee under any such
mortgage, indenture or other instrument; or

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

                  Upon receipt by the Trustee of any Notice of Default pursuant
to this Section 501 with respect to Securities of a series all or part of which
is represented by a Book-Entry Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such Notice of Default, which record date shall be at the close of business on
the day the Trustee receives such Notice of Default. The Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to join in such Notice of Default, whether or not such Holders remain Holders
after such record date; provided, that unless Holders of at least 10% in
principal amount of the Outstanding Securities of such series, or their proxies,
shall have joined in such Notice of Default prior to the day which is 90 days
after such record date, such Notice of Default shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph

                                       36
<PAGE>   46
shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of
such 90-day period, a new Notice of Default which is identical to a Notice of
Default which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 501.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default 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 (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series 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, except that no such
declaration shall be required upon the occurrence of an Event of Default
specified in Section 501(5) or 501(6).

                  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 and premium, if any, of
Securities of that series which have

                                       37
<PAGE>   47
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.

                  Upon receipt by the Trustee of any written notice declaring
such an acceleration, or recision and annulment thereof, with respect to
Securities of a series all or part of which is represented by a Book-Entry
Security, a record date shall be established for determining Holders of
Outstanding Securities of such series entitled to join in such notice, which
record date shall be at the close of business on the day the Trustee receives
such notice. The Holders on such record date, or their duly designated proxies,
and only such Persons, shall be entitled to join in such notice, whether or not
such Holders remain Holders after such record date; provided, that unless such
declaration of acceleration, or rescission and annulment, as the case may be,
shall have become effective by virtue of the requisite percentage having joined
in such notice prior to the day which is 90 days after such record date, such
declaration of acceleration, or rescission and annulment, as the case may be,
shall automatically and without further action by any Holder be canceled and of
no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy
of a Holder, from giving, after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission or annulment thereof, as
the case may be, which has been canceled pursuant to the proviso to the
preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 502.

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, 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 the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding

                                       38
<PAGE>   48
for the collection of the sums so due and unpaid, may prosecute such proceeding
to judgment or final decree and may enforce the same against the Company or any
other obligor upon such Securities and collect the moneys adjudged or decreed to
be payable in the manner provided by law out of the property of the Company or
any other obligor upon such Securities, wherever situated.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series 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 Proofs 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.

                  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.

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.

                                       39
<PAGE>   49
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 the amounts then due and unpaid for
principal of 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

                  THIRD:  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;

                  (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,

                                       40
<PAGE>   50
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, 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) any interest on such Security on the Stated Maturity or
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 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

                                       41
<PAGE>   51
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, and

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

                  Upon receipt by the Trustee of any written notice directing
the time, method or place of conducting any such proceeding or exercising any
such trust or power, with respect to Securities of a series all or part of which
is represented by a Book-Entry Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that unless Holders of a majority in principal amount of the
Outstanding Securities of such series shall have joined in such notice prior to
the day which is 90 days after such record date, such notice shall automatically
and without further action by any Holder be canceled and of no further effect.
Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, after expiration of such 90-day period, a new notice identical to a
notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 512.

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


                                       42
<PAGE>   52
                  (2) in respect of a covenant or provision hereof which under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to waive any past
default hereunder. If a record date is fixed, the Holders on such record date,
or their duly designated proxies, and only such Persons, shall be entitled to
waive any default hereunder, whether or not such Holders remain Holders after
such record date; provided, that unless such majority in principal amount shall
have been obtained prior to the date which is 90 days after such record date,
any such waiver previously given shall automatically and without further action
by any Holder be canceled and of no further effect.

                  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 (including reasonable attorneys' fees and expenses) against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act.

SECTION 515. Waiver of 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 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.

<PAGE>   53
                  The duties and responsibilities of the Trustee shall be as
provided by the Trust Indenture Act and this Indenture. 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, upon receipt by a Responsible Officer of such notice of
default, 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(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or 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 conclusively rely and shall be fully
protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or
document (whether in its original or facsimilie form) believed by it to be
genuine and to have been signed or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein

                  (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 of its own selection
and the advice of such counsel or any Opinion of Counsel shall be full and
complete authorization and

                                       44
<PAGE>   54
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 at the expense of the Company and shall incur no liability or
additional liability of any kind by reason of such inquiry or investigation of
Trustee;

                  (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; and

                  (8) the rights, privileges and benefits (including right to
indemnity) of trustee are extended to and shall be enforceable by the trustee in
each of its capacities hereunder and each agent employed to act hereunder.

SECTION 604. Not Responsible for Recitals or Issuance of Securities.

                  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 the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. The Trustee
or any Authenticating Agent shall not be accountable for the use or application
by the Company of Securities or the process 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

                                       45
<PAGE>   55
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 such compensation
as shall be agreed upon from time to time in writing 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 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 willful misconduct; and

                  (3) to fully indemnify the Trustee and any predecessor Trustee
for, and to hold it harmless against, any and all loss, claim, damage, liability
or expense (including taxes other than taxes based on the income of the Trustee)
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. Disqualification; 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.

SECTION 609. Corporate Trustee Required; Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
a Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and

                                       46
<PAGE>   56
surplus of at least $50,000,000. If such Person 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 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 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.

                  (1) 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.

                  (2) 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, at
the expense of the Company, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

                  (3) 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.

                  (4) If at any time:

                      (a) 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

                      (b) 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

                      (c) 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, (i) the Company by a Board
Resolution may remove the Trustee with respect to all Securities, or (ii)
subject to Section 514, any Holder who has been a 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

                                       47
<PAGE>   57
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

                  (5) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, with respect to the Securities of one or more series, the Company, by
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.

                  (6) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
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.

                  (1) 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.

                                       48
<PAGE>   58
                  (2) 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 deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (a) 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, (b) 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 (c) 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.

                  (3) 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 paragraph (2) and (3) of this Section, as the case may be.

                  (4) 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 corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of

                                       49
<PAGE>   59
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 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 corporation 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 corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation 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.

                                       50
<PAGE>   60
                  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 mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. 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.

                  The Company agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section.

                  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.

                  With the consent of the Holders of not less than a majority in

                  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 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.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such
record date or their duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental indenture, whether or not such Holders
remain Holders after such record date; provided, that unless such consent shall
have become effective by virtue of the requisite percentage having been obtained
prior to the date which is 90 days after such record date, any such consent
previously given shall automatically and without further action by any Holder be
canceled and of no further effect.

                  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.

                  In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications

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 of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

SECTION 905. Conformity with Trust Indenture Act.

                  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.

<PAGE>   67
                  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.


                                   ARTICLE TEN
                                    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 of that series and this Indenture.

SECTION 1002. Maintenance of Office or Agency.

                  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 or exchange 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.


                                       58
<PAGE>   68
                  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 (i) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) 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, and 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.

                  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

                                       59
<PAGE>   69
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.

SECTION 1004. Corporate Existence.

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

SECTION 1005. Defeasance of Certain Obligations.

                  If this Section 1005 is specified, as contemplated by Section
301, to be applicable to Securities of any series, (i) the Company may omit to
comply with any term, provision or condition of those certain covenants
established pursuant to Sections 301 and 1004 hereof and to which this Section
1005 is to be made applicable, and (ii) Section 501(4) with respect to such
covenants to which this Section 1005 is to be made applicable shall be deemed
not to be an Event of Default, in each case with respect to the Securities of
that series, provided that the following conditions have been satisfied:

                  (1) With reference to this Section 1005, the Company has
deposited or caused to be deposited with the Trustee (or another trustee
satisfying the requirements of Section 609) irrevocably (irrespective of whether
the conditions in subparagraphs (2), (3), (4), (5) and (6) below have been
satisfied, but subject to the provisions of Section 402(3) and the last
paragraph of Section 1003), as trust funds in trust, specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of the
Securities of that series, (A) money in an amount, or (B) U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide not later than the opening
of business on the due date of any payment referred to in clause (i) or (ii) of
this subparagraph (1) money in an amount, or (C) a combination thereof,
sufficient, in the opinion of a nationally recognized firm of independent
certified public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge (i) the principal (and premium,
if any) and each installment of principal (and premium, if any) and interest on
the Outstanding Securities of that series on the Stated Maturity of such
principal or installment of principal or interest and (ii) any mandatory sinking
fund payments or analogous payments applicable to Securities of such series on
the day on which such payments are due and payable in accordance with the terms
of this Indenture and of such Securities;


                                       60
<PAGE>   70
                  (2) Such deposit shall not cause the Trustee with respect to
the Securities of that series to have a conflicting interest for purposes of the
Trust Indenture Act with respect to the Securities of any series;

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

                  (4) No Event of Default or event which with the giving of
notice or lapse of time, or both, would become an Event of Default with respect
to the Securities of that series shall have occurred and be continuing on the
date of such deposit and no Event of Default under Section 501(5) or Section
501(6) or event which with the giving of notice or lapse of time, or both, would
become an Event of Default under Section 501(5) or Section 501(6) shall have
occurred and be continuing on the 91st day after such date;

                  (5) The Company has delivered to the Trustee an Opinion of
Counsel to the effect that Holders of the Securities of such series will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance of certain obligations and will be subject to
federal income tax on the same amount and in the same manner and at the same
times, as would have been the case if such deposit and defeasance had not
occurred; and

                  (6) 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 defeasance contemplated by this
Section have been complied with.

SECTION 1006. 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.

                  The Company shall deliver to the Trustee, as soon as possible
and in any event within five days after the Company becomes aware of the
occurrence of any Event of Default or an event which, with notice or the lapse
of time or both, would constitute an Event of Default, an Officers' Certificate
setting forth the details of such Event of Default or default and the action
which the Company proposes to take with respect thereto.

SECTION 1007. Waiver of Certain Covenants.

                  The Company may omit in any particular instance to comply with
any term, provision or condition of those certain covenants contained herein or
established pursuant to Section 301 hereof to which this Section 1007 is said to
be applicable, with respect to the Securities of any series if before the time
for such compliance the Holders of at least a majority in principal amount of
the Outstanding Securities of such series 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

                                       61
<PAGE>   71
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.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to waive any such term,
provision or condition. If a record date is fixed, the Holders on such record
date or their duly designated proxies, and only such Persons, shall be entitled
to waive any such term, provision or condition hereunder, whether or not such
Holders remain Holders after such record date; provided, that unless the Holders
of at least a majority in principal amount of the Outstanding Securities of such
series shall have waived such term, provision or condition prior to the date
which is 90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be canceled and of not
further effect.

SECTION 1008. Calculation of Original Issue Discount.

                  The Company shall file with the Trustee promptly at the end of
each calendar year (I) a written notice specifying the amount of the original
issue discount (including daily rates and accrual periods) accrued on
Outstanding Securities as of the end of such year and (ii) such other specific
information relating to such original issue discount as may then be relevant
under the Internal Revenue Code of 1986, as amended from time to time.


                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

                  Securities of any series which are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 301 for Securities of any
series) in accordance with this Article.

SECTION 1102. Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or by action taken pursuant to a Board
Resolution. In case of any redemption at the election of the Company of less
than all the Securities of any series, 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
provided in the terms of such Securities or

                                       62
<PAGE>   72
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

SECTION 1103. Selection by Trustee of Securities to Be Redeemed.

                  If less than all the Securities of any series are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate (but subject to compliance with
the rules of any Securities Exchange on which the Securities of such series may
be listed) and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities of that series or
any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of that series; provided that if less than all the Securities of a
series having different tenor are to be redeemed, the specific Securities to be
redeemed shall be selected by the Company. If less than all of the Securities of
such series and of a specified tenor are to be redeemed, the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

                  The Trustee shall promptly notify the Company (or, in the case
of a selection by the Company, the Company shall promptly notify the Trustee) in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

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


                                       63
<PAGE>   73
                  (3) if less than all the Outstanding Securities of any series
are to be redeemed, the identification (and, in the case of partial redemption
of any Securities, the principal amounts) of the particular Securities 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 such Securities are 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) the CUSIP numbers, if any, of the Securities to be
redeemed.

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

SECTION 1105. Deposit of Redemption Price.

                  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.

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 shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.


                                       64
<PAGE>   74
                  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. If a Book-Entry Security is so
surrendered, such new Security so issued shall be a new Book-Entry Security.


                                 ARTICLE TWELVE
                                  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 a series except as otherwise
specified as contemplated by Section 301 for Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment". If provided for by the terms of Securities of
any series, 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 of any series as provided for by the
terms of Securities of such series.

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 the Securities of such series required to be made
pursuant to the terms

                                       65
<PAGE>   75
of such Securities as provided for by the terms of such series; provided that
such Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities 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 60 days prior to each sinking fund payment date
for any series of Securities, the Company will deliver to the Trustee an
Officers' Certificate specifying the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, 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
of that series pursuant to Section 1202 and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 and not more than 60 days before
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.

                  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.


                                ARTICLE THIRTEEN
                                  SUBORDINATION

SECTION 1301. Securities Subordinated to Senior Indebtedness.

                  The Company, for itself and its successors, and each Holder,
by his or her acceptance of Securities, agrees that the payment of the principal
of or any premium and interest on the Securities is subordinated, to the extent
and in the manner provided in this Article Thirteen, to the right of payment in
full to all present and future Senior Indebtedness, and that these subordination
provisions are for the benefit of the holders of Senior Indebtedness.

                  The provisions of this Article Thirteen are for the benefit of
the holders of the Senior Indebtedness from time to time (and their successors
and assigns) and shall be enforceable directly by them and their respective
representatives directly against the Company, the Trustee and the Holders (and
their successors and assigns). The provisions of this Article Thirteen shall be
a continuing agreement and shall be irrevocable and shall remain in full force

                                       66
<PAGE>   76
and effect until payment in the full of the Senior Indebtedness in cash or cash
equivalents, and shall constitute a continuing and irrevocable offer to all
Persons who become holders of, or continue to hold, Senior Indebtedness (whether
such Senior Indebtedness was created or acquired before or after the issuance of
the Securities), each of which holders shall be deemed for the purposes hereof
to have acquired Senior Indebtedness in reliance upon the provisions of this
Article Thirteen. The provision of this Article Thirteen shall survive the
commencement of any reorganization or other proceedings with respect to the
Company or any other Person and the discharge of any claim in connection with
such reorganization or other proceedings, including, without limitation, the
discharge of any Senior Indebtedness.

                  The holders of the Senior Indebtedness and their respective
representatives are hereby authorized to demand specific performance of the
provisions of this Article Thirteen at any time when the Company or any Holder
shall have failed to comply with any provision of this Article Thirteen
applicable to it, and the Company and each Holder hereby irrevocably waives any
defense based on the adequacy of a remedy at law that might be asserted as a bar
to the remedy of specific performance hereof in any action brought therefor by
the holders of the Senior Indebtedness and their respective representatives.

SECTION 1302. No Payment on Securities in Certain Circumstances

                  (a) No payment shall be made by or on behalf of the Company on
account of any obligation or, to the extent the subordination thereof is
permitted by applicable law, claim in respect of the Securities, including the
principal of or any premium or interest on the Securities, or to redeem (or make
a deposit in redemption of), defease (other than payments made by the Trustee
pursuant to Article 4 with respect to a defeasance permitted by this Indenture,
including the subordination provisions herein) or acquire any of the Securities
for cash, property or securities, (i) upon the maturity of the Designated Senior
Indebtedness or any other Senior Indebtedness with an aggregate principal amount
in excess of $1,000,000 by lapse of time, acceleration or otherwise, unless and
until all principal of or any premium and interest on such Senior Indebtedness
and all other obligations in respect thereof shall first be paid in full in cash
or cash equivalents or such payment is duly provided for, or unless and until
any such maturity by acceleration has been rescinded or waived or (ii) in the
event of default in payment of any principal of or any premium or interest on or
any other amount payable in respect of the Designated Senior Indebtedness or any
other Senior Indebtedness with an aggregate principal amount in excess of
$1,000,000 when it becomes due and payable, whether at maturity or at a date
fixed for prepayment or by declaration or otherwise, unless and until such
payment default has been cured or waived or has otherwise ceased to exist.

                  (b) Upon the happening of a default (any event that, after
notice or passage of time would be an event of default) or an event of default
(any event that permits the holders of Senior Indebtedness or their
representative or representatives immediately to accelerate its maturity) with
respect to any Senior Indebtedness, other than a default in payment of the
principal of or any premium or interest on such Senior Indebtedness, upon
written notice of

                                       67
<PAGE>   77
such default or event of default given to the Company and the Trustee by the
holders of a majority of the principal amount outstanding of such Designated
Senior Indebtedness or their representative or at such time as there is no
Designated Senior Indebtedness by the holders of a majority of the principal
amount outstanding of all Senior Indebtedness or their representative or
representatives, or if such default or event of default results from the
acceleration of the Securities, immediately upon such acceleration, then, unless
and until such default or event of default has been cured or waived or otherwise
has ceased to exist, no payment may be made by or on behalf of the Company with
respect to any obligation or claim in respect of the Securities, including the
principal of or any premium or interest on the Securities or to redeem (or make
a deposit in redemption of), defease or acquire any of the Securities for cash,
property or securities. Notwithstanding the foregoing, unless the Senior
Indebtedness in respect of which such default or event of default exists has
been declared due and payable in its entirety within 180 days after the date
written notice of such default or event of default is delivered as set forth
above or the date of such acceleration, as the case may be (the "Payment
Blockage Period"), and such declaration or acceleration has not been rescinded,
the Company shall be required then to pay all sums not paid to the Holders of
the Securities during the Payment Blockage Period due to the foregoing
prohibitions and to resume all other payments as and when due on the Securities.
Any number of such notices may be given; provided, however, that (i) during any
360 consecutive days, only one Payment Blockage Period shall commence and (ii)
any such default or event of default that existed upon the commencement of a
Payment Blockage Period may not be the basis for the commencement of any other
Payment Blockage Period, unless such default or event of default shall have been
cured or waived for a period of not less than 90 consecutive days.

                  (c) In the event that, notwithstanding the foregoing
provisions of this Section 1302, any payment or distribution of assets of the
Company from any source whether in cash, property or securities, shall be
received by the Trustee or the Holders on account of any obligation or claim in
respect of the Securities at a time when such payment or distribution is
prohibited by the foregoing provisions, such payment or distribution shall be
held in trust for the benefit of the holders of Senior Indebtedness, and shall
be paid or delivered by the Trustee or such Holders, as the case may be, to the
holders of the Senior Indebtedness remaining unpaid or unprovided for or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any of such Senior
Indebtedness may have been issued, ratably according to the aggregate amounts
remaining unpaid on account of the Senior Indebtedness held or represented by
each, for application to the payment of all Senior Indebtedness remaining
unpaid, to the extent necessary to pay or to provide for the payment in full in
cash or cash equivalents of all such Senior Indebtedness, after giving effect to
any concurrent payment or distribution to the holders of such Senior
Indebtedness.

                   The Company shall give prompt written notice to the Trustee
of any default or event of default, and any cure or waiver thereof, or any
acceleration under any Senior

                                       68
<PAGE>   78
Indebtedness or under any agreement pursuant to which Senior Indebtedness may
have been issued.

SECTION 1303.     Securities Subordinated to Prior Payment of All Senior
                  Indebtedness on Dissolution, Liquidation or Reorganization of
                  Company.

                  Upon any distribution of assets of the Company upon any
dissolution, winding up, total or partial liquidation or reorganization or
readjustment of the Company, whether voluntary or involuntary, in bankruptcy,
insolvency, receivership or similar proceeding or upon assignment for the
benefit of creditors, or any other marshalling of the assets and liabilities of
the Company or otherwise:

                  (a) the holders of all Senior Indebtedness would first be
         entitled to receive payment in full in cash or cash equivalents (or
         have such payment duly provided for) of the principal, premium and
         interest payable in respect thereof before the Holders would be
         entitled to receive any payment on account of the principal of or any
         premium and interest on the Securities;

                  (b) any payment or distribution of assets of the Company of
         any kind or character, from any source, whether in cash, property or
         securities to which the Holders or the Trustee on behalf of the Holders
         would be entitled, except for the subordination provisions of this
         Article Thirteen, would be paid by the liquidating trustee or agent or
         other person making such a payment or distribution directly to the
         holders of Senior Indebtedness remaining unpaid or unprovided for or
         their representative or representatives, or to the trustee or trustees
         under any indenture pursuant to which any instruments evidencing any of
         such Senior Indebtedness may have been issued, ratably according to the
         aggregate amounts remaining unpaid on account of the Senior
         Indebtedness held or represented by each, for application to the
         payment of all Senior Indebtedness remaining unpaid, to the extent
         necessary to pay or provide for the payment in full in cash or cash
         equivalents of all such Senior Indebtedness, after giving effect to any
         concurrent payment or distribution to the holders of such Senior
         Indebtedness; and

                  (c) in the event that, notwithstanding the foregoing, any
         payment or distribution of assets of the Company from any source,
         whether in cash, property or securities, shall be received by the
         Trustee or the Holders on account of principal of or interest on the
         Securities before all Senior Indebtedness is paid in full in cash or
         cash equivalents (or such payment is duly provided for), such payment
         or distribution (subject to the provision of Sections 1306 and 1307)
         shall be held in trust by the Trustee or such Holders for the benefit
         of the holders of the Senior Indebtedness, or their representative,
         ratably according to the respective amounts of Senior Indebtedness held
         or represented by each, to the extent necessary to make payment in full
         (except as such payment otherwise shall have been provided for) of all
         Senior Indebtedness remaining unpaid after giving effect to all
         concurrent payments and distributions and all provisions

                                       69
<PAGE>   79
         therefor to the holders of such Senior Indebtedness, but only to the
         extent that as to any holder of Senior Indebtedness, as promptly as
         practicable following notice from the Trustee to the holders of Senior
         Indebtedness that such prohibited payment has been received by the
         Trustee or Holder(s), such holder (or a representative therefor)
         notifies the Trustee in writing of the amounts then due and owing on
         the Senior Indebtedness held by such holder and only the amounts
         specified in such notices to the Trustee shall be paid to the holders
         of Senior Indebtedness.

                  The Company shall give prompt written notice to the Trustee of
any dissolution, winding up, liquidation or reorganization of the Company or
assignment for the benefit of creditors by the Company.

SECTION 1304. Securityholders to Be Subrogated to Rights of Senior Indebtedness.

                  Subject to the payment in full in cash or cash equivalents of
all Senior Indebtedness (or provision made for its payment), the Holders of
Securities shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until all amounts owing on the Securities
shall be paid in full, in cash or cash equivalents and for the purpose of such
subrogation no such payments or distributions to the holders of Senior
Indebtedness by or on behalf of the Company, or by or on behalf of the Holders
by virtue of this Article Thirteen, which otherwise would have been made to the
Holders shall, as between the Company and the Holders, be deemed to be payment
by the Company to or on account of the Senior Indebtedness, it being understood
that the provisions of this Article Thirteen are and are intended solely for the
purpose of defining the relative rights of the Holders, on the one hand, and the
holders of Senior Indebtedness, on the other hand.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article Thirteen
shall have been applied, pursuant to the provisions of this Article Thirteen, to
the payment of amounts payable under Senior Indebtedness, then the Holders shall
be entitled to receive from the holders of such Senior Indebtedness any payments
or distributions received by such holders of Senior Indebtedness in excess of
the amount sufficient to pay all amounts payable under or in respect of the
Senior Indebtedness in full in cash or cash equivalents.

SECTION 1305. Obligations of the Company Unconditional.

                  Nothing contained in this Article Thirteen or elsewhere in
this Indenture or in the Securities is intended to or shall impair, as between
the Company and the Holders, the obligation of the Company, which is absolute
and unconditional, to pay to the Holders the principal of or any premium and
interest on the Securities as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the Holders and creditors of the Company other than the holders of the
Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or
any Holder from

                                       70
<PAGE>   80
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article Thirteen, of
the holders of Senior Indebtedness in respect of cash, property or securities of
the Company received upon the exercise of any such remedy. Notwithstanding
anything to the contrary in this Article Thirteen or elsewhere in this Indenture
or in the Securities, upon any distribution of assets of the Company referred to
in this Article Thirteen, the Trustee and the Holders shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction in which
such dissolution, winding up, liquidation or reorganization proceeding is
pending, or a certificate of the liquidating trustee or agent or other person
making any distribution to the Trustee or to the Holders for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Thirteen.
Except as otherwise provided in this Section 1305, in the event of any
inconsistency between the provisions of this Article Thirteen, on the one part,
and any other provision of this Indenture or any provision of the Securities, on
the other part, the provisions of this Article Thirteen shall govern.

SECTION 1306.  Trustee Entitled to Assume Payments Not Prohibited in Absence of
               Notice.

                  The Trustee shall not at any time be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee unless and until the Trustee shall have received, no later than
three Business Days prior to such payment, written notice thereof from the
Company or from one or more holders of Senior Indebtedness or from any
representative therefor and, prior to the receipt of any such written notice,
the Trustee shall be entitled in all respects conclusively to assume that no
such fact exists.

SECTION 1307. Application by Trustee of Assets Deposited with It.

                  Money or U.S. Government Obligations deposited in trust with
the Trustee pursuant to and in accordance with Section 401 shall be for the sole
benefit of Holders and, to the extent (i) the making of such deposit by the
Company shall not have been in contravention of any term or provision of any
agreement creating or evidencing Senior Indebtedness and (ii) allocated for the
payment of Securities, shall not be subject to the subordination provisions of
this Article Thirteen. Otherwise, any deposit of assets by the Company with the
Trustee or any Paying Agent (whether or not in trust) for the payment of
principal of or interest on any Securities shall be subject to the provisions of
Sections 1301, 1302, 1303 and 1304; provided that, if prior to the second
Business Day preceding the date on which by the terms of this Indenture any such
assets may become distributable for any purpose (including without limitation,
the payment of either principal of or interest on any Securities) the Trustee or
such Paying Agent shall not have received with respect to such assets the
written notice provided for in Section 1306, then the Trustee or such Paying
Agent shall have full power and authority to receive such assets and to apply
the same to the purpose for which they were received, and

                                       71
<PAGE>   81
shall not be affected by any notice to the contrary which may be received by it
on or after such date.

SECTION 1308.  Subordination Rights Not Impaired by Acts or Omissions of the
               Company, the Trustee or Holders of Senior Indebtedness.

                  No act, or failure to act, of any holder of the Senior
Indebtedness or their respective representatives (including without limitation,
any action referred to in this Section 1308), the Company, the Trustee, any
Holder or any other Person with the terms, covenants or the provisions of this
Article Thirteen (regardless of any knowledge thereof which any such holder of
the Senior Indebtedness may have or otherwise be charged with) or any
reorganization or similar proceeding with respect to the Company shall affect
the provisions of this Article Thirteen, the obligations owed by the Company,
the Trustee or any Holder to the holders of the Senior Indebtedness under this
Article Thirteen or the rights of any holder of Senior Indebtedness under this
Article Thirteen.

                  The Company, the Trustee and each Holder each hereby agree
that the taking of any of the following actions, with or without notice, by the
holders of the Senior Indebtedness and their respective representatives, will
not in any way affect the provisions of this Article 13: (i) changing the
manner, place or terms of payment or extending the time of payment of, or
renewing or altering, any agreement or instrument creating, evidencing or
governing any Senior Indebtedness, or consenting to any amendment or change of
any terms of any such agreement or instrument, each as amended from time to
time; (ii) granting extensions or renewals of any such agreement or instrument
and any other indulgence with respect thereto, or effecting any release,
compromise or settlement with respect thereto; (iii) releasing any Person liable
in any manner for the payment or collection of any Senior Indebtedness; (iv)
substituting, exchanging or releasing or otherwise disposing of any item of
security at any time securing any Senior Indebtedness, whether or not the
collateral, if any, received upon the exercise of such power shall be of a
character or value the same as or different from the character or value of the
item of security released; (v) exercising or refraining from exercising any
rights or remedies against the Company or any other Person; and (vi) taking any
other action, or refraining from taking any action, that, in the absence of
authority granted hereby, could have the effect of impairing, invalidating or
rendering unenforceable, in whole or in part, or otherwise affecting, any of the
provisions of this Article Thirteen.

SECTION 1309.  Holders Authorize Trustee to Effectuate Subordination of
               Securities.

                  Each Holder of the Securities by his or her acceptance thereof
authorizes and expressly directs the Trustee on his or her behalf to take such
action in accordance with the terms of this Indenture as may be necessary or
appropriate to effectuate the subordination provisions contained in this Article
Thirteen and to protect the rights of the Holders pursuant to this Indenture,
and appoints the Trustee his or her attorney-in-fact for such purpose,
including, in the event of any dissolution, winding up, liquidation or any
reorganization or

                                       72
<PAGE>   82
similar proceeding with respect to the Company (whether in bankruptcy,
insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or any other marshalling of assets and liabilities of the Company)
tending towards liquidation of the business and assets of the Company, the
immediate filing of a claim for the unpaid balance of his or her Securities in
the form required in said proceedings and cause said claim to be approved. If
the Trustee does not file a proper claim or proof of debt in the form required
in such proceeding prior to 30 days before the expiration of the time to file
such claim or claims, then the holders of the Senior Indebtedness or their
respective representatives are hereby authorized to have the right to file and
are hereby authorized to file an appropriate claim for and on behalf of the
Holders of said Securities. Nothing herein contained shall be deemed to
authorize the Trustee or the holders of Senior Indebtedness or their respective
representatives 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 or the holders of Senior Indebtedness or their respective
representatives to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 1310. Right of Trustee to Hold Senior Indebtedness.

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

SECTION 1311. Article Thirteen Not to Prevent Events of Default.

                  The failure to make a payment on account of principal of or
interest on the Securities by reason of any provision of this Article Thirteen
shall not be construed as preventing the occurrence of a Default or an Event of
Default under Section 501 or in any way prevent the Holders from exercising any
right hereunder other than the right to receive payment on the Securities.

SECTION 1312. No Fiduciary Duty of Trustee to Holders of Senior Indebtedness.

                  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness, and shall not be liable to any such holders
(other than for its willful misconduct, bad faith or negligence) if it shall in
good faith mistakenly pay over or distribute to the Holders of Securities or the
Company or any other person, cash, property or securities to which any holders
of Senior Indebtedness shall be entitled by virtue of this Article Thirteen or
otherwise. Nothing in this Section 1312 shall affect the obligation of any other
such person to hold such payment for the benefit of, and to pay such payment
over to, the holders of Senior Indebtedness or their representative.

         Re:       Registration Statement on Form S-3

Gentlemen:

         At your request, we have examined the Registration Statement on Form
S-3 ("Registration Statement") relating to the registration and sale from time
to time by you of up to an aggregate of $500,000,000 of debt securities ("Debt
Securities") notes and/or other evidences of indebtedness representing unsecured
obligations of AMERCO in amounts, at prices, and on terms to be determined at
the time of offering. Capitalized terms used but not otherwise defined herein
shall have the meanings ascribed to them in the Registration Statement.

In connection with this opinion, we have examined:

         a. the Registration Statement;

         b. the Articles of Incorporation of AMERCO, as amended, as filed with
the Nevada Secretary of State; and

         c. the Bylaws of AMERCO certified by the Secretary of AMERCO.

         We have assumed that the proceeds from the sale of the Debt Securities
will be used for valid corporate purposes.

         We have assumed the authenticity of all documents submitted to us as
originals, the genuineness of all signatures, the legal capacity of natural
persons and the conformity to originals
<PAGE>   2
AMERCO
March 3, 1999
Page 2


of all copies of all documents submitted to us. We have relied upon the
certificates of all public officials and corporate officers with respect to the
accuracy of all matters contained therein.

         We further assume the following:

         a. The Registration Statement being declared effective under the
Securities Act of 1933, as amended;

         b. The due authorization of any resolutions of the Board of Directors
of AMERCO by which the Debt Securities are to be issued;

         c. The due authorization by the appropriate members of the Board of
Directors of AMERCO and the subsequent execution and delivery of the agreements
or indentures pursuant to which the Debt Securities are to be issued, and the
authentication of any such agreements or indentures under the Trust Indenture
Act of 1939, as amended, if required;

         d. The due execution, registration and delivery of the certificate or
instrument or instruments evidencing the Debt Securities; and

         e. The Debt Securities being established, issued and sold in the manner
specified in the Registration Statement and the exhibits thereto, in accordance
with corporate and governmental authorities and not in violation of any
applicable law, agreement or instrument.

Based upon the foregoing and subject to the following it is our opinion that:

         The Debt Securities to be issued by AMERCO will be legally issued and
will be the binding obligations of AMERCO subject to bankruptcy, insolvency,
moratorium and similar laws affecting the rights of creditors generally and to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law) and except that certain
provisions of the Debt Securities may not be enforceable in whole or in part
under the laws of the State of Nevada.

         You have informed us that you intend to issue the Debt Securities from
time to time on a delayed or continuous basis. Accordingly, this opinion is
subject to the laws, including the rules and regulations, as in effect on the
date hereof. We understand that prior to issuing any Debt Securities you will
advise us in writing of the terms thereof, will afford us an opportunity to
review the operative documents pursuant to which such Debt Securities are to be
issued (including the applicable Prospectus Supplement) and will file such
supplement or amendment to this opinion (if any) as we reasonably consider
necessary or appropriate by reason of the terms of

the Debt Securities.

         Nothing herein shall be deemed an opinion as to the laws of any
jurisdiction other than the State of Nevada.

         This opinion is intended solely for the use of AMERCO in connection
with the Registration Statement. It may not be relied upon by any other person
or for any other purpose, or reproduced or filed publicly by any person, without
the written consent of this firm.

         We hereby consent to the use of this opinion as an exhibit to the
Registration Statement, and we further consent to the use of our name under the
caption "Legal Opinions" in the Registration Statement and Prospectus and in
"Legal Matters" in any Prospectus Supplement.
We disclaim liability as an expert under law.

                                                      Very truly yours,
