 4. On February 16, 1996, the Company completed the acquisition of PRC, Inc.
    ("PRC"), a diversified information technology company, from The Black &
    Decker Corporation for a preliminary purchase price of $425 million in cash.
    This acquisition is being accounted for under the purchase method of
    accounting.
 
    On May 15, 1996, the Company acquired Steerage Corp. ("Steerage") from an
    investment partnership for approximately $158 million in cash, inclusive of
    $52.4 million for repayment of existing Steerage debt. Steerage, which
    conducts operations through its wholly-owned subsidiary Sperry Marine, Inc.
    ("Sperry Marine"), is a provider of advanced electronic navigation and
    guidance systems to military and commercial customers. This acquisition
    will be accounted for under the purchase method of accounting.

     The unaudited pro forma sales, net earnings, primary and fully diluted
earnings per share for the nine months ended April 30, 1996, as if the
combinations had occurred on August 1, 1995, were $3.1 billion, $110.3 million,
$2.31 and $2.31, respectively. These pro forma results are based on preliminary
allocations of the acquisition costs among net assets acquired and intangibles.
The excess purchase price over the estimated fair value of tangible net assets
acquired is being amortized over a period of 30 years for PRC and 25 years for
Sperry Marine. These pro forma amounts are not necessarily indicative of what
the results of operations would have been if the combinations had occurred on
August 1, 1995. Additionally, they may not be indicative of future results.
 
     In connection with the PRC acquisition, the Company issued $300 million
principal amount of 7.75% debentures due March 15, 2026 and $100 million
principal amount of 6.98% debentures due March 15, 2036. The Company also
borrowed, on a short-term basis, approximately $110 million under an existing
revolving credit agreement in connection with the acquisition of Sperry Marine
on May 15, 1996.

                   PART I. FINANCIAL INFORMATION (CONTINUED)
 
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     Sales were $1.0 billion and $2.58 billion for the third quarter and nine
months of fiscal year 1996, representing improvements of 17% and 10% over the
corresponding prior year's amounts of $861.4 million and $2.34 billion,
respectively. Segment operating profit for the third quarter and nine months of
the current fiscal year increased to $83.7 million and $225.8 million, compared
with $73.2 million and $202.0 million for the same periods a year ago. Those
increases resulted in improvements of 9% and 12% in net earnings, respectively.
Interest expense was higher in the current year's periods due to the debt
incurred to finance the acquisition of PRC in February of 1996.
 
     Sales from the Advanced Electronics' businesses in the third quarter of
fiscal year 1996 were $582.3 million compared with $408.1 million in the third
quarter of fiscal year 1995. For the first nine months of fiscal year 1996,
sales were $1.37 billion compared with $1.15 billion for the nine months of last
fiscal year. Operating profit for this segment amounted to $42.2 million and
$105.6 million in the third quarter and nine months ended April 30, 1996
compared with $31.8 million and $89.5 million in the prior year's periods. These
increases reflect the impact of recent acquisitions, including PRC, and improved
operating efficiency. With reported revenues of $712 million in its fiscal year
ended December 31, 1995, PRC is a diversified information technology company
that designs, develops, integrates and supports computer-based information
systems and re-engineers business processes for the U.S. Government, commercial
customers and state and local governments. Although management expects PRC to
contribute significantly in sales, the profit margin for this type of business
is lower in comparison with that historically experienced by the other
businesses in the Advanced Electronics segment. Operating margin for the
Advanced Electronics segment for the third quarter of fiscal year 1996 was 7.3%,
compared with 7.8% for the third quarter of fiscal year 1995. Backlog for this
segment at April 30, 1996 was $3.55 billion, significantly higher than the $1.75
billion at July 31, 1995 primarily due to the PRC acquisition. The Marine
Engineering and Production segment achieved improved operating margins on lower
sales. Sales for the third quarter and nine months of fiscal year 1996 were
$352.8 million and $1.01 billion, compared with $397.3 million and $1.03 billion
for the prior year's periods. The decrease in sales was attributable to lower
construction activity on long-term contracts nearing completion, partially
offset by activity on new contracts and others moving into more advanced stages
of production. Operating margins improved as a result of cost reduction efforts
and increased earnings rates on long-term contracts. The estimated earnings at
completion are adjusted as long-term contracts progress in the production
process and as uncertainties are resolved or, conversely, identified. Backlog
for the Marine Engineering and Production segment at April 30, 1996 was $3.36
billion, comparable to that at July 31, 1995 of $3.31 billion. The Interconnect
Products segment continued to benefit from strong demand for its
electronics-related products during the first nine months of the current fiscal
year. Management believes that its on-going cost reduction efforts and focus on
opportunities for new products will contribute to the solid performances by this
segment.
 
     Management's continued focus on strategic acquisitions has resulted in the
May 15, 1996 acquisition of Sperry Marine for cash of approximately $158
million, which included repayment of $52.4 million in outstanding debt. With
reported revenues of $145 million for its fiscal year ended December 31, 1995,
Sperry Marine is a worldwide leader in the design, development, manufacture,
service and supply of advanced electronic navigation and guidance systems for
marine and aircraft uses.
 
     Interest expense increased to $8.1 million and $14.5 million for the third
quarter and nine months of the current fiscal year compared with $2.9 million
and $9.1 million for the same periods of the prior fiscal year. In connection
with the acquisition of PRC, the Company borrowed $400 million under an existing
revolving credit agreement with various banks at an interest rate of 5.5125%.
This indebtedness was replaced by the subsequent issuance, on March 19, 1996, of
7.75% and 6.98% debentures due 2026 and 2036, respectively. The Company also
borrowed, on a short-term basis, approximately $110 million under the
aforementioned revolving credit agreement in connection with the Sperry Marine
acquisition on May 15, 1996. The Company expects to repay this indebtedness with
existing funds and cash flow from operations.
 
     The Company completed the first nine months of fiscal year 1996 with $151.7
million in cash and marketable securities, compared with $110.7 million at July
31, 1995. Management believes that existing funds, along with cash flow from
operations, are sufficient to meet anticipated cash requirements.

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
Securityholders 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)

by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by an officer of a corporation or a member of a partnership, on
behalf of such corporation or partnership, 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 ownership of Securities shall be proved by the Security

authorization, direction, notice, consent, waiver or other action, the Company
may, at its option, by Board Resolution, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so. Such record date shall be the later of 10 days prior to
the first solicitation of such action or the date of the most recent list of
Holders furnished to the Trustee pursuant to Section 701. If such a record date
is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other action may be given before or after the record date, but only
the Holders of record at the close of business on the record date shall be
deemed to be Holders for the purposes of determining whether Holders of the
requisite proportion of Securities Outstanding have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other action, and for that purpose the Securities Outstanding shall be
computed as of the record date; provided that no such authorization, agreement
or consent by the Holders on the record date shall be deemed effective unless it
shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date, and that no such authorization, agreement
or consent may be amended, withdrawn or revoked once given by a Holder, unless
the Company shall provide for such amendment, withdrawal or revocation in
conjunction with such solicitation of authorizations, agreements or consents or
unless and to the extent required by applicable law.

        (e) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind the Holder of
every Security issued upon the transfer thereof or in exchange therefor or in
lieu thereof, in respect of anything done 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.

        SECTION 105. Notices, etc., to Trustee and Company. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Securityholders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

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


<PAGE>   23
                                       14


              (2) the Company by the Trustee or by any Securityholder shall be
        sufficient for every purpose hereunder (except as provided in Section
        501(4) or, in the case of a request for repayment, as specified in the
        Security carrying the right to repayment) 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 paragraph of this
        instrument, Attention: Treasurer, or at any other address previously
        furnished in writing to the Trustee by the Company.

        SECTION 106. Notices to Securityholders, Waiver. Where this Indenture or
any Security provides for notice to Securityholders of any event, such notice
shall be sufficiently given (unless otherwise herein or in such Security
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Securityholder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Securityholders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Securityholder
shall affect the sufficiency of such notice with respect to other
Securityholders. Where this Indenture or any Security 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 Securityholders 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 as a result
of a strike, work stoppage or otherwise, it shall be impractical to mail notice
of any event to any Securityholder when such notice is required to be given
pursuant to any provision of this Indenture, then any method of notification as
shall be satisfactory to the Trustee and the Company shall be deemed to be a
sufficient giving of such notice.

        SECTION 107. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with the duties imposed by any of Sections 310 to
317, inclusive, of the Trust Indenture Act through operation of Section 318(c)
thereof, such imposed duties shall control.

        SECTION 108. Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

        SECTION 109.  Successors and Assigns.  All covenants and agreements in
this Indenture by the Company shall bind its successors and assigns, whether
so expressed or not.

        SECTION 110. Separability Clause. In case any provision in this
Indenture or in the Securities shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

        SECTION 111. Benefits of Indenture. Nothing in this Indenture or in any
Securities, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Authenticating Agent or Paying Agent,
the Security Registrar and the Holders of Securities (or such of them as may be
affected thereby), any benefit or any legal or equitable right, remedy or claim
under this Indenture.

        SECTION 112.  Governing Law.  This Indenture shall be construed in
accordance with and governed by the laws of the State of New York.

        SECTION 113.  Counterparts.  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 TWO

                                 SECURITY FORMS

        SECTION 201. Forms Generally. The Securities shall have such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon, as may be
required to comply with the rules of any securities exchange, or as may,
consistently herewith, be determined by the officer executing such Securities,
as evidenced by such officer's execution of the Securities. Any portion of the
text of any Security may be set forth on the reverse thereof, with an
appropriate reference thereto on the face of the Security.

        The definitive Securities shall be printed, lithographed or engraved or
produced by any combination of these methods on steel engraved borders or may be
produced in any other manner, all as determined by the officer execut-

<PAGE>   25
                                       16


ing such Securities, as evidenced by such officer's execution of such
Securities, subject, with respect to the Securities of any series, to the rules
of any securities exchange on which such Securities are listed.

        SECTION 202. Forms of Securities. Each Security shall be in one of the
forms approved from time to time by or pursuant to a Board Resolution, or
established in one or more indentures supplemental hereto. Prior to the delivery
of a Security to the Trustee for authentication in any form approved by or
pursuant to a Board Resolution, the Company shall deliver to the Trustee the
Board Resolution by or pursuant to which such form of Security has been
approved, which Board Resolution shall have attached thereto a true and correct
copy of the form of Security which has been approved thereby or, if a Board
Resolution authorizes a specific officer or officers to approve a form of
Security, a certificate of such officer or officers approving the form of
Security attached thereto. Any form of Security approved by or pursuant to a
Board Resolution must be acceptable as to form to the Trustee, such acceptance
to be evidenced by the Trustee's authentication of Securities in that form or a
certificate signed by a Responsible Officer of the Trustee and delivered to the
Company.

        SECTION 203. Form of Trustee's Certificate of Authentication. The form
of Trustee's Certificate of Authentication for any Security issued pursuant to
this Indenture shall be substantially as follows:

                    TRUSTEE'S CERTIFICATE OF AUTHENTICATION

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

                                                   The Bank of New York,
                                                     as Trustee,

                                                   By: ____________________

                                                       Authorized Signatory

        SECTION 204. Securities Issuable in the Form of a Global Security. (a)
If the Company shall establish pursuant to Sections 202 and 301 that the
Securities of a particular series are to be issued in whole or in part in the
form of one or more Global Securities, then the Company shall execute and the
Trustee or

<PAGE>   26
                                       17


its agent shall, in accordance with Section 303 and the Company Order delivered
to the Trustee or its agent thereunder, authenticate and make available for
delivery, such Global Security or Securities, which (i) shall represent, and
shall be denominated in an amount equal to the aggregate principal amount of,
the Outstanding Securities of such series to be represented by such Global
Security or Securities, or such portion thereof as the Company shall specify in
a Company Order, (ii) shall be registered in the name of the Depositary for such
Global Security or Securities or its nominee, (iii) shall be delivered by the
Trustee or its agent to the Depositary or pursuant to the Depositary's
instruction and (iv) shall bear a legend substantially to the following effect:
"Unless this certificate is presented by an authorized representative of the
Depositary to Issuer or its agent for registration of transfer, exchange, or
payment, and any certificate issued is registered in the name of the nominee of
the Depositary or in such other name as is requested by an authorized
representative of the Depositary (and any payment is made to the nominee of the
Depositary or to such other entity as is requested by an authorized
representative of the Depositary), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR
VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered
owner hereof, the nominee of the Depositary, has an interest herein."

        (b) Notwithstanding any other provision of this Section 204 or of
Section 305, and subject to the provisions of paragraph (c) below, unless the
terms of a Global Security expressly permit such Global Security to be exchanged
in whole or in part for individual Securities, a Global Security may be
transferred, in whole but not in part and in the manner provided in Section 305,
only to a nominee of the Depositary for such Global Security, or to the
Depositary, or a successor Depositary for such Global Security selected or
approved by the Company, or to a nominee of such successor Depositary.

        (c) (i)If at any time the Depositary for a Global Security notifies the
Company that it is unwilling or unable to continue as Depositary for such Global
Security or if at any time the Depositary for the Securities for such series
shall no longer be eligible or in good standing under the Securities Exchange
Act of 1934, as amended, or other applicable statute or regulation, the Company
shall appoint a successor Depositary with respect to such Global Security. If a
successor Depositary for such Global Security is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company will execute, and the Trustee

<PAGE>   27
                                       18


or its agent, upon receipt of a Company Request for the authentication and
delivery of individual Securities of such series in exchange for such Global
Security, will authenticate and make available for delivery individual
Securities of such series of like tenor and terms in an aggregate principal
amount equal to the principal amount of the Global Security in exchange for such
Global Security.

        (ii) The Company may at any time and in its sole discretion determine
that the Securities of any series or portion thereof issued or issuable in the
form of one or more Global Securities shall no longer be represented by such
Global Security or Securities. In such event the Company will execute, and the
Trustee, upon receipt of a Company Request for the authentication and delivery
of individual Securities of such series in exchange in whole or in part for such
Global Security, will authenticate and make available for delivery individual
Securities of such series of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of such Global Security
or Securities representing such series or portion thereof in exchange for such
Global Security or Securities.

        (iii) If specified by the Company pursuant to Sections 202 and 301 with
respect to Securities issued or issuable in the form of a Global Security, the
Depositary for such Global Security may surrender such Global Security in
exchange in whole or in part for individual Securities of such series of like
tenor and terms in definitive form on such terms as are acceptable to the
Company and such Depositary. Thereupon the Company shall execute, and the
Trustee or its agent shall authenticate and make available for delivery, without
service charge, (1) to each Person specified by such Depositary a new Security
or Securities of the same series of like tenor and terms and of any authorized
denomination as requested by such Person in aggregate principal amount equal to
and in exchange for such Person's beneficial interest as specified by such
Depositary in the Global Security; and (2) to such Depositary a new Global
Security of like tenor and terms and in an authorized denomination equal to the
difference, if any, between the principal amount of the surrendered Global
Security and the aggregate principal amount of Securities delivered to Holders
thereof.

        (iv) In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee or its agent will
authenticate and make available for delivery individual Securities in definitive
registered

<PAGE>   28
                                       19


form in authorized denominations. Upon the exchange of the entire principal
amount of a Global Security for individual Securities, such Global Security
shall be canceled by the Trustee or its agent. Except as provided in the
preceding paragraph, Securities issued in exchange for a Global Security
pursuant to this Section shall be registered in such names and in such
authorized denominations as the Depositary for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee or the Security Registrar. The Trustee shall deliver at its
Corporate Trust Office such Securities to the Persons in whose names such
Securities are so registered.

                                 ARTICLE THREE

                                 THE SECURITIES

        SECTION 301. General Title; General Limitations; Issuable in Series;
Terms of Particular Series. The aggregate principal amount of Securities which
may be authenticated and delivered and Outstanding under this Indenture is not
limited.

        The Securities may be issued in one or more series up to an aggregate
principal amount of Securities as from time to time may be authorized by the
Board of Directors. All Securities of each series under this Indenture shall in
all respects be equally and ratably entitled to the benefits hereof with respect
to such series without preference, priority or distinction on account of the
actual time of the authentication and delivery or Stated Maturity of the
Securities of such series.

        Each series of Securities shall be created either by or pursuant to a
Board Resolution or by an indenture supplemental hereto. The Securities of each
such series may bear such date or dates, be payable at such place or places,
have such Stated Maturity or Maturities, be issuable at such premium over or
discount from their face value, bear interest at such rate or rates, from such
date or dates, payable in such installments and on such dates and at such place
or places to the Holders of Securities registered as such on such Regular Record
Dates, or may bear no interest, and may be redeemable or repayable at such
Redemption Price or Prices or Repayment Price or Prices, as the case may be,
whether at the option of the Holder or otherwise, and upon such terms, all as
shall be provided for in or pursuant to the Board Resolution or in the
supplemental indenture creating that series. There may also be established 

<PAGE>   29
                                       20

in or pursuant to a Board Resolution or in a supplemental indenture prior to the
issuance of Securities of each such series, provision for:

               (1) the exchange or conversion of the Securities of that series,
        at the option of the Holders thereof, for or into new Securities of a
        different series or other securities except shares of capital stock of
        the Company or any subsidiary of the Company or securities directly or
        indirectly convertible into or exchangeable for any such shares;

               (2)    a sinking or purchase fund or other analogous obligation;

               (3)    a limitation on the aggregate principal amount of the
        Securities of that series;

                (4) the exchange of Securities of that series, at the option of
        the Holders thereof, for other Securities of the same series of the same
        aggregate principal amount of a different authorized kind or different
        authorized denomination or denominations, or both;

                (5) the appointment by the Trustee of an Authenticating Agent in
        one or more places other than the location of the office of the Trustee
        with power to act on behalf of the Trustee and subject to its direction
        in the authentication and delivery of the Securities of any one or more
        series in connection with such transactions as shall be specified in the
        provisions of this Indenture or in or pursuant to the Board Resolution
        or the supplemental indenture creating such series;

               (6) the portion of the principal amount of Securities of the
        series, if other than the principal amount thereof, which shall be
        payable upon declaration of acceleration of the Maturity thereof
        pursuant to Section 502 or provable in bankruptcy pursuant to Section
        504;

               (7) any Event of Default with respect to the Securities of such
        series, if not set forth herein, and any additions, deletions or other
        changes to the Events of Default set forth herein that shall be
        applicable to the Securities of such series;

                (8) any covenant solely for the benefit of the Securities of
        such series and any additions, deletions or other changes to the
        provisions of Sections 1006 and 1007 that shall be applicable to the
        Securities of that series;

               (9) the inapplicability of Section 403 of this Indenture to the
        Securities of such series and any covenant with respect to Section
        403(b) established in or pursuant to a Board Resolution or in a
        supplemental indenture as described above that has not already been
        established herein;

               (10) If the Securities of the series shall be issued in whole or
        in part in the form of a Global Security or Securities, the terms and
        conditions,

<PAGE>   30
                                       21


         if any, upon which such Global Security or Securities may be exchanged
         in whole or in part for other individual Securities; and the Depositary
         for such Global Security or Securities; and

                (11)  any other terms of the series,

all upon such terms as may be determined in or pursuant to a Board Resolution or
in a supplemental indenture with respect to such series. All Securities of the
same series shall be substantially identical in tenor and effect except as to
denomination and except if issued pursuant to Section 311.

        The form of the Securities of each series shall be established pursuant
to the provisions of this Indenture in or pursuant to the Board Resolution or in
the supplemental indenture creating such series. The Securities of each series
shall be distinguished from the Securities of each other series in such manner,
reasonably satisfactory to the Trustee, as the Board of Directors may determine.

        Unless otherwise provided with respect to Securities of a particular
series, the Securities of any series may only be issuable in registered form,
without coupons.

        Any terms or provisions in respect of the Securities of any series
issued under this Indenture may be determined pursuant to this Section by
providing for the method by which such terms or provisions shall be determined.

        SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be provided in the provisions of this
Indenture or in or pursuant to the Board Resolution or the supplemental
indenture creating such series. In the absence of any such provisions with
respect to the Securities of any series, the Securities of that series shall be
issuable only in fully registered form in denominations of $1,000 and any
integral multiple thereof.

        SECTION 303. Execution, Authentication and Delivery and Dating. The
Securities shall be executed on behalf of the Company by its Chairman of the
Board, its Vice Chairman, its President or one of its Vice Presidents. 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.

<PAGE>   31
                                       22


        At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication; and the Trustee shall, upon Company Order,
authenticate and make available for delivery such Securities as in this
Indenture provided and not otherwise.

        Prior to any such authentication and delivery, the Trustee shall be
entitled to receive, in addition to any Officers' Certificate and Opinion of
Counsel required to be furnished to the Trustee pursuant to Section 102, and the
Board Resolution and any certificate relating to the issuance of the series of
Securities required to be furnished pursuant to Section 202, an Opinion of
Counsel stating that:

               (1) all instruments furnished to the Trustee conform to the
        requirements of the Indenture and constitute sufficient authority
        hereunder for the Trustee to authenticate and deliver such Securities;

               (2)    the form and terms of such Securities have been
        established in conformity with the provisions of this Indenture;

               (3) all laws and requirements with respect to the execution and
        delivery by the Company of such Securities have been complied with, the
        Company has the corporate power to issue such Securities and such
        Securities have been duly authorized and delivered by the Company and,
        assuming due authentication and delivery by the Trustee, constitute
        legal, valid and binding obligations of the Company enforceable in
        accordance with their terms (subject, as to enforcement of remedies, to
        applicable bankruptcy, reorganization, insolvency, moratorium or other
        laws and legal principles affecting creditors' rights generally from
        time to time in effect and to general equitable principles, whether
        applied in an action at law or in equity) and entitled to the benefits
        of this Indenture, equally and ratably with all other Securities, if
        any, of such series Outstanding;

               (4)    the Indenture is qualified under the Trust Indenture

        Act; and

               (5)    such other matters as the Trustee may reasonably request;

and, if the authentication and delivery relates to a new series of Securities
created by an indenture supplemental hereto, also stating that all laws and
requirements with respect to the form and execution by the Company of the
supplemental indenture with respect to that series of Securities have been
complied with, the Company has corporate power to execute and deliver any such
supplemental indenture and has taken all necessary corporate action for those
purposes and any such supplemental indenture has been executed and delivered and
constitutes the legal, valid and binding obligation of the Com-

<PAGE>   32
                                       23


pany enforceable in accordance with its terms (subject, as to enforcement of
remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or
other laws and legal principles affecting creditors' rights generally from time
to time in effect and to general equitable principles, whether applied in an
action at law or in equity) and, if the authentication and delivery relates to
Securities of a series issued pursuant to Section 311, paragraphs (2) and (3) of
the foregoing opinion shall read as follows:

               "(2) the form of such Securities and the procedures for
        determining the terms of such Securities as set forth in the procedures
        relating thereto referred to in Section 311 have been established in
        conformity with the provisions of this Indenture, and

               (3) all laws and requirements with respect to the execution and
        delivery by the Company of such Securities have been complied with, the
        Company has the corporate power to issue such Securities and such
        Securities have been duly authorized by the Company and when duly
        executed by the Company and completed and authenticated in accordance
        with the Indenture and issued, delivered and paid for in accordance with
        the applicable selling agency or distribution agreement, will have been
        duly issued under the Indenture and will constitute the legal, valid and
        binding obligations of the Company enforceable in accordance with their
        terms (subject, as to enforcement of remedies, to applicable bankruptcy,
        reorganization, insolvency, moratorium or other laws and legal
        principles affecting creditors' rights generally from time to time in
        effect and to general equitable principles, whether applied in an action
        at law or in equity) and entitled to the benefits of this Indenture,
        equally and ratably with all other Securities, if any, of such series
        Outstanding."

        The Trustee shall not be required to authenticate such Securities if the
issue thereof will adversely affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture.

        Unless otherwise provided in the form of Security for any series, all
Securities shall be dated the date of their 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.

        SECTION 304. Temporary Securities. Pending the preparation of definitive
Securities of any series, the Company may execute, and, upon receipt of the
documents required by Section 303, together with a Company Order, the Trustee
shall authenticate and make available for delivery, 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 such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, 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, without charge to the Holder; and upon
surrender for cancellation of any one or more temporary Securities the Company
shall execute and the Trustee shall authenticate and make available for delivery
in exchange therefor a like principal amount of definitive Securities of such
series of authorized denominations and of like tenor and terms. Until so
exchanged the temporary Securities of such series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

        SECTION 305. Registration, Transfer and Exchange. The Company shall keep
or cause to be kept a register or registers (herein sometimes 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, or of
Securities of a particular series, and for transfers of Securities or of
Securities of such series. Any such register shall be in written form or in any
other form capable of being converted into written form within a reasonable
time. At all reasonable times the information contained in such register or
registers shall be available for inspection by the Trustee at the office or
agency to be maintained by the Company as provided in Section 1002. There shall
be only one Security Register per series of Securities.

        Subject to Section 204, upon surrender for transfer of any Security of
any series at the office or agency of the Company in a Place of Payment, the

<PAGE>   34
                                       25


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
such series of any authorized denominations, of a like aggregate principal
amount and Stated Maturity and of like tenor and terms.

        Subject to Section 204, at the option of the Holder, Securities of any
series may be exchanged for other Securities of such series of any authorized
denominations, of a like aggregate principal amount and Stated Maturity and of
like tenor and terms, 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 make available for
delivery, the Securities which the Securityholder making the exchange is
entitled to receive.

        All Securities issued upon any 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 transfer or exchange.

        Every Security presented or surrendered for transfer or 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.

        Unless otherwise provided in the Security to be transferred or
exchanged, no service charge shall be made on any Securityholder for any
transfer or exchange of Securities, but the Company may (unless otherwise
provided in such Security) require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any transfer
or exchange of Securities, other than exchanges pursuant to Section 304 or 906
not involving any transfer.

        The Company shall not be required (i) to issue, transfer or exchange any
Security 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
such series selected for redemption under Section 1103 and ending at the close
of business on the date of such mailing, or (ii) to transfer or exchange any
Security so selected for redemption in whole or in part.

<PAGE>   35
                                       26


        None of the Company, the Trustee, any agent of the Trustee, any Paying
Agent or the Security Registrar will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests of a Global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

        SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If (i)
any mutilated Security is surrendered to the Trustee, or the Company and the
Trustee receive evidence to their satisfaction of the destruction, loss or theft
of any Security, and (ii) there is delivered to the Company and the Trustee such
security or indemnity as may be required by them to save each 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 upon
its request the Trustee shall authenticate and make available for delivery, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Security, a new Security of like tenor, series, stated maturity and principal
amount, 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 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 the same 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.  Unless
otherwise provided with respect to such Security pursuant to Section 301,
interest

<PAGE>   36
                                       27


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 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 registered
Holder on the relevant Regular Record Date by virtue of his having been such
Holder, and, except as hereinafter provided, such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in Clause (1) or
Clause (2) below:

               (1) The Company may elect to make payment of any Defaulted
        Interest to the Persons in whose names any such Securities (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 such Security and the date of the proposed
        payment, and at the same time the Company shall deposit with the Trustee
        an amount of money equal to the aggregate amount proposed to be paid in
        respect of such Defaulted Interest or shall make arrangements
        satisfactory to the Trustee for such deposit prior to the date of the
        proposed payment, such money when deposited to be held in trust for the
        benefit of the Persons entitled to such Defaulted Interest as in this
        Clause provided. Thereupon the Trustee shall fix a Special Record Date
        for the payment of such Defaulted Interest which shall be not more than
        15 nor less than 10 days prior to the date of the proposed payment and
        not less than 10 days after the receipt by the Trustee of the notice of
        the proposed payment. The Trustee shall promptly notify the Company of
        such Special Record Date and, in the name and at the expense of the
        Company, shall cause notice of the proposed payment of such Defaulted
        Interest and the Special Record Date therefor to be mailed, first class
        postage prepaid, to the Holder of each such Security 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 mailed as
        aforesaid, such Defaulted Interest shall be paid to the Persons in whose
        names such Securities (or their respective Predecessor Securities) are
        registered on such Special Record Date and shall no longer be payable
        pursuant to the following Clause (2).

               (2)    The Company may make payment of any Defaulted Interest
        in any other lawful manner not inconsistent with the requirements of
        any

<PAGE>   37
                                       28


         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.

        If any installment of interest the Stated Maturity of which is on or
prior to the Redemption Date for any Security called for redemption pursuant to
Article Eleven is not paid or duly provided for on or prior to the Redemption
Date in accordance with the foregoing provisions of this Section, such interest
shall be payable as part of the Redemption Price of such Securities.

        Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon 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. The Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name any
Security is registered as the owner of such Security for the purpose of
receiving payment of principal of (and premium, if any), and (subject to Section
307) interest on, such Security and for all other purposes whatsoever, whether
or not such Security be overdue, and neither the Company, the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the contrary.

        SECTION 309. Cancellation. All Securities surrendered for payment,
redemption, transfer, or exchange or credit against a sinking fund shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and, if not already canceled, shall be promptly canceled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Security shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. The Trustee shall deliver all canceled Securities
to the Company.

        SECTION 310. Computation of Interest. Unless otherwise provided as
contemplated in Section 301, interest on the Securities shall be calculated on
the basis of a 360-day year of twelve 30-day months.

                                       29


        SECTION 311. Medium-Term Securities. Notwithstanding any contrary
provision herein, if all Securities of a series are not to be originally issued
at one time, it shall not be necessary for the Company to deliver to the Trustee
an Officers' Certificate, Board Resolution, supplemental indenture, Opinion of
Counsel or Company Order otherwise required pursuant to Sections 102, 202, 301
and 303 at or prior to the time of authentication of each Security of such
series if such documents are delivered to the Trustee or its agent at or prior
to the authentication upon original issuance of the first Security of such
series to be issued; provided that any subsequent request by the Company to the
Trustee to authenticate Securities of such series upon original issuance shall
constitute a representation and warranty by the Company that as of the date of
such request, the statements made in the Officers' Certificate or other
certificates delivered pursuant to Sections 102 and 202 shall be true and
correct as if made on such date.

        A Company Order, Officers' Certificate or Board Resolution or
supplemental indenture delivered by the Company to the Trustee in the
circumstances set forth in the preceding paragraph may provide that Securities
which are the subject thereof will be authenticated and delivered by the Trustee
or its agent on original issue from time to time in the aggregate principal
amount established for such series pursuant to such procedures acceptable to the
Trustee as may be specified from time to time by Company Order upon the
telephonic, electronic or written order of persons designated in such Company
Order, Officers' Certificate, supplemental indenture or Board Resolution (any
such telephonic or electronic instructions to be promptly confirmed in writing
by such persons) and that such persons are authorized to determine, consistent
with such Company Order, Officers' Certificate, supplemental indenture or Board
Resolution, such terms and conditions of said Securities as are specified in
such Company Order, Officers' Certificate, supplemental indenture or Board
Resolution.

        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.

                              SATISFACTION AND DISCHARGE

        SECTION 401. Satisfaction and Discharge of Indenture. This Indenture
shall cease to be of further effect with respect to any series of Securities
(except as to any surviving rights of conversion or transfer or exchange of
Securities of such series expressly provided for herein or in the form of
Security for such series), and the Trustee, on demand of and at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture as to such series, when

        (1)    either

               (A) all Securities of that series theretofore authenticated and
        delivered (other than (i) Securities of such series which have been
        destroyed, lost or stolen and which have been replaced or paid as
        provided in Section 306, and (ii) Securities of such series for whose
        payment money has theretofore been deposited in trust or segregated and
        held in trust by the Company and thereafter repaid to the Company or
        discharged from such trust, as provided in Section 1003) have been
        delivered to the Trustee canceled or for cancellation; or

               (B) all such Securities of that series not theretofore delivered 
        to the Trustee canceled or for cancellation

                      (i)  have become due and payable, or

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

                      (iii) are to be called for redemption within one year
               under arrangements satisfactory to the Trustee for the giving of
               notice of redemption by the Trustee in the name, and at the
               expense, of the Company,

               and the Company, in the case of (i), (ii) or (iii) above, has
               deposited or caused to be deposited with the Trustee as trust
               funds in trust for the purpose an amount, which shall be
               immediately due and payable, sufficient to pay and discharge the
               entire indebtedness on such Securities not theretofore delivered
               to the Trustee canceled or for cancellation, for principal (and
               premium, if any) and interest to the date of such deposit (in the
               case of Securities which have become due and payable), or to the
               Stated Maturity or Redemption Date, as the case may be;

               (2) the Company has paid or caused to be paid all other sums
        payable hereunder by the Company with respect to the Securities of such
        series; and

<PAGE>   40
                                       31


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

Notwithstanding the satisfaction and discharge of this Indenture with respect to
any series of Securities, the obligations of the Company to the Trustee with
respect to that series under Section 607 shall survive and the obligations of
the Trustee under Sections 402 and 1003 shall survive.

        SECTION 402. Application of Trust Money. All money deposited with the
Trustee pursuant to Section 401 or Section 403 shall be held in trust and
applied by it, in accordance with the provisions of the series of Securities in
respect of which it was deposited and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal (and premium, if any) and interest for whose payment such money
has been deposited with the Trustee; but such money need not be segregated from
other funds except to the extent required by law.

        SECTION 403. Defeasance Upon Deposit of Funds or Government Obligations.
Unless pursuant to Section 301 provision is made that this Section shall not be
applicable to the Securities of any series, at the Company's option, either (a)
the Company shall be deemed to have been Discharged (as defined below) from its
obligations with respect to any series of Securities after the applicable
conditions set forth below have been satisfied or (b) the Company shall cease to
be under any obligation to comply with any term, provision or condition set
forth in Sections 1006 and 1007 (and any other Sections applicable to such
Securities that are determined pursuant to Section 301 to be subject to this
provision) with respect to any series of Securities at any time after the
applicable conditions set forth below have been satisfied:

               (1) the Company shall have deposited or caused to be deposited
        irrevocably with the Trustee as trust funds in trust, specifically
        pledged as security for, and dedicated solely to, the benefit of the
        Holders of the Securities of such series (i) money in an amount, or (ii)
        the equivalent in direct obligations of, or obligations the principal of
        and interest on which are fully guaranteed by, the United States of
        America which through the payment of interest and principal in respect
        thereof in accordance with their terms will provide, not later than one
        day before the due date of any payment, money in an amount, or (iii) a
        combination of (i) and (ii),

<PAGE>   41
                                       32


        sufficient, in the opinion (with respect to (ii) and (iii)) of a
        nationally recognized firm of independent public accountants expressed
        in a written certification thereof delivered to the Trustee, to pay and
        discharge each installment of principal (including mandatory sinking
        fund payments) and any premium of, interest on and any repurchase
        obligations with respect to the outstanding Securities of such series
        on the dates such installments of interest or principal or repurchase
        obligations are due;

               (2) no Event of Default or event (including such deposit) which
        with notice or lapse of time would become an Event of Default with
        respect to the Securities of such series shall have occurred and be
        continuing on the date of such deposit; and

               (3) the Company shall have 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 the Company's exercise of its option under this Section 403
        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
        option had not been exercised, and, in the case of Securities being
        Discharged, such opinion shall be based upon at least one of the
        following authorities (issued, enacted or promulgated after the date of
        this Indenture), substantially on point and to the foregoing effect: (i)
        a public ruling of the Internal Revenue Service, (ii) a private ruling
        of the Internal Revenue Service issued to the Company with respect to
        the Securities, (iii) a provision of the Internal Revenue Code, or (iv)
        a final regulation promulgated by the Department of the Treasury.

        "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Securities of such series and to have satisfied all the obligations under this
Indenture relating to the Securities of such series (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), except (A) the rights of Holders of Securities to receive, from the trust
fund described in clause (1) above, payment of the principal and any premium of
and any interest on such Securities when such payments are due; (B) the
Company's obligations with respect to such Securities under Sections 305, 306,
402, 1002 and 1003; and (C) the rights, powers, trusts, duties and immunities of
the Trustee hereunder.

                                    REMEDIES

        SECTION 501. Events of Default. "Event of Default", wherever used
herein, means with respect to any series of Securities any one of the following
events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body), unless such event is either inapplicable
to a particular series or it is specifically deleted or modified in or pursuant
to the supplemental indenture or Board Resolution creating such series of
Securities or in the form of Security for such series:

               (1) default in the payment of any interest upon any Security of
        that series when it becomes due and payable, and continuance of such
        default for a period of 30 days; or

        warranty of the Company in this Indenture in respect of the Securities
        of such series (other than a covenant or warranty in respect of the

        breach of which is elsewhere in this Section specifically dealt with),
        all of such covenants and warranties in the Indenture which are not
        expressly stated to be for the benefit of a particular series of
        Securities being deemed in respect of the Securities of all series for
        this purpose, and continuance of such default or breach for a period of
        90 days after receipt by the Company from the Trustee or by the Company
        and the Trustee from the Holders of at least 25% in principal amount of
        the Outstanding Securities of such series, a written notice, by
        registered or certified mail, 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 of an order for relief against the Company under
        the Federal Bankruptcy Act by a court having jurisdiction in the
        premises or a decree or order by a court having jurisdiction in the
        premises adjudging the Company a bankrupt or insolvent under any other
        applicable Federal, or State law, or the entry of a decree or order

        or any other applicable Federal or State law, or appointing a 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 unstayed and in effect for a period of 90
        consecutive days; or

               (6) the consent by the Company to the institution of bankruptcy
        or insolvency proceedings against it, or the filing by it of a petition
        or answer or consent seeking reorganization or relief under the Federal
        Bankruptcy Code or any other applicable Federal or State law, or the
        consent by it to the filing of any such petition or to the appointment
        of a receiver, liquidator, assignee, trustee, sequestrator (or other
        similar official) of the Company or of any substantial part of its
        property, or the making by it of an assignment for the benefit of
        creditors, or the admission by it in writing of its inability to pay its
        debts generally as they become due, or the taking of corporate action by
        the Company in furtherance of any such action; or

               (7) any other Event of Default provided in the supplemental
        indenture or Board Resolution under which such series of Securities is
        issued or in the form of Security for such series.

        SECTION 502. Acceleration of Maturity, Rescission and Annulment. If an
Event of Default described in paragraph (1), (2), (3), (4) or (7) (if the Event
of Default under paragraph (4) or (7) is with respect to less than all series of
Securities then Outstanding) of Section 501 occurs and is continuing with
respect to any series, then and in each and every such case, unless the
principal of all the Securities of such series shall have already become due and
payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding hereunder
(each such series acting as a separate class), by notice in writing to the
Company (and to the Trustee if given by Holders), may declare the principal
amount (or, if the Securities of such 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 Securities of such series and all accrued
interest thereon to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Securities of such series contained to the
contrary notwithstanding. If an Event of Default described in paragraph (4) or
(7) (if the Event of Default under paragraph (4) or (7) is with respect to all
series of Securities then Outstanding), (5) or (6) of Section 501 occurs and is
continuing, then and in each and every such case, unless the principal of all
the Securities shall have already become due and payable, either the Trustee or
the Holders of not less

<PAGE>   44
                                       35


than 25% in aggregate principal amount of all the Securities then Outstanding
hereunder (treated as one class), by notice in writing to the Company (and to
the Trustee if given by Holders), may declare the principal amount (or, if any
Securities are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms thereof) of all the Securities then
Outstanding and all accrued interest thereon to be due and payable immediately,
and upon any such declaration the same shall become and shall be immediately due
and payable, anything in this Indenture or in the Securities contained to the
contrary notwithstanding.

        At any time after such a declaration of acceleration has been made with
respect to the Securities of any or all series, as the case may be, 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 such 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 installments of interest on the
               Securities of such series,

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

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

                      (D) all sums paid or advanced by the Trustee hereunder and
               the reasonable compensation, expenses, disbursements and advances
               of the Trustee, its agents and counsel and all other amounts due
               the Trustee under Section 607;

        and

               (2) all Events of Default with respect to such series of
        Securities, other than the nonpayment of the principal of the Securities
        of such series which have become due solely by such acceleration, have
        been cured or waived as provided in Section 513.

                                       36


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

        SECTION 503.  Collection of Indebtedness and Suits for Enforcement by
Trustee.  The Company covenants that if

               (1)    default is made in the payment of any installment of
        interest on any Security of any series when such interest becomes due
        and payable, or

               (2)    default is made in the payment of the principal of (or
        premium, if any, on) any Security at the Maturity thereof, or

               (3) default is made in the payment of any sinking or purchase
        fund or analogous obligation when the same becomes due by the terms of
        the Securities of any series,

and any such default continues for any period of grace provided with respect to
the Securities of such series, the Company will, upon demand of the Trustee, pay
to it, for the benefit of the Holder of any such Security (or the Holders of any
such series in the case of Clause (3) above), the whole amount then due and
payable on any such Security (or on the Securities of any such series in the
case of Clause (3) above) for principal (and premium, if any) and interest, with
interest, to the extent that payment of such interest shall be legally
enforceable, upon the overdue principal (and premium, if any) and upon overdue
installments of interest, at such rate or rates as may be prescribed therefor by
the terms of any such Security (or of Securities of any such series in the case
of Clause (3) above); 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 and all other amounts due the Trustee under Section 607.

        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, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities of such series and
collect the money 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 any series of Securities occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce

<PAGE>   46
                                       37


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

               (i) to file and prove a claim for the whole amount of principal
        (and premium, if any) and interest owing and unpaid in respect of the
        Securities and to file such other papers or documents as may be
        necessary and advisable in order to have the claims of the Trustee
        (including any claim for the reasonable compensation, expenses,
        disbursements and advances of the Trustee, its agents and counsel and
        all other amounts due the Trustee under Section 607) and of the
        Securityholders allowed in such judicial proceeding, and

               (ii)   to collect and receive any moneys or other property
        payable or deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, liquidator, sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each
Securityholder to make such payment to the Trustee and in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 607.

        Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Securityholder 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 of any series may be prosecuted and enforced by the Trustee without
the possession of any of the Securities of such series 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 agent and
counsel and any other amounts due the Trustee under Section 607, be for the
ratable benefit of the Holders of the Securities of the series in respect of
which such judgment has been recovered.

        SECTION 506. Application of Money Collected. Any money collected by the
Trustee with respect to a series of Securities 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 premium,
if any) or interest, upon presentation of the Securities of such series 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 upon the
        Securities of that series for principal (and premium, if any) and
        interest, in respect of which or for the benefit of which such money has
        been collected, ratably, without preference or priority of any kind,
        according to the amounts due and payable on such Securities for
        principal (and premium, if any) and interest, respectively.

        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 Securities of
        such series;

               (2) the Holders of not less than 25% in principal amount of the,
        Outstanding Securities of such 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;

<PAGE>   48
                                       39


               (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 such
        series;

it being understood and intended that no one or more Holders of Securities of
such series 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 Holders of Securities of such series, or to obtain or to
seek to obtain priority or preference over any other such Holders or to enforce
any right under this Indenture, except in the manner herein provided and for the
equal and proportionate benefit of all the Holders of all Securities of such
series.

        SECTION 508. Unconditional Right Of Securityholders To Receive
Principal, Premium and Interest. Notwithstanding any other provisions 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 premium, if any)
and (subject to Section 307) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in the case of redemption or
repayment, on the Redemption Date or Repayment Date, as the case may be) and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

        SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Securityholder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, then and in every such case the Company, the Trustee and the
Securityholders shall, subject to any determination in such proceeding, be
restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Securityholders shall
continue as though no such proceeding had been instituted.

        SECTION 510.  Rights and Remedies Cumulative.  No right or remedy
herein conferred upon or reserved to the Trustee or to the Securityholders is
intended to be exclusive of any other right or remedy, and every right and

<PAGE>   49
                                       40


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 Security 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
Securityholders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Securityholders, as the case may be.

        SECTION 512. Control by Securityholders. 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) the Trustee shall have the right to decline to follow any
        such direction if the Trustee, being advised by counsel, determines that
        the action so directed may not lawfully be taken or would conflict with
        this Indenture or if the Trustee in good faith shall, by a Responsible
        Officer, determine that the proceedings so directed would involve it in
        personal liability or be unjustly prejudicial to the Holders not taking
        part in such direction, and

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

        SECTION 513. Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a
default not theretofore cured 

               (1) in the payment of the principal of (or premium, if any) or
        interest on any Security of such series, or in the payment of any
        sinking or purchase fund or analogous obligation with respect to the
        Securities of such series, or

<PAGE>   50
                                       41


               (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.

        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. All parties to this Indenture agree,
and each Holder of any Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Securityholder, or
group of Securityholders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series to which the suit relates, or
to any suit instituted by any Securityholder for the enforcement of the payment
of the principal of (or premium, if any) or interest on any Security on or after
the respective Stated Maturities expressed in such Security (or, in the case of
redemption or repayment, on or after the Redemption Date or Repayment Date, as
the case may be).

        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. (a) Except during the
continuance of an Event of Default with respect to any series of Securities,

                 (1) the Trustee undertakes to perform such duties and only such
         duties as are specifically set forth in this Indenture with respect to
         the Securities of such series, and no implied covenants or obligations
         shall be read into this Indenture against the Trustee; and

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


         (b) In case an Event of Default with respect to any series of
Securities has occurred and is continuing, the Trustee shall exercise with
respect to the Securities of such series such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.


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

                 (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                 (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture with respect to the Securities of such series; and
<PAGE>   52
                                       43


                 (4) 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.


         (d) 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. Within 90 days after the occurrence of
any default hereunder with respect to Securities of any series, the Trustee
shall transmit by mail to all Securityholders of such series, as their names and
addresses appear in the Security Register, notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default in the payment of the
principal of (or premium, if any) or interest on any Security of such series or
in the payment of any sinking or purchase fund installment or analogous
obligation with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interests of the Securityholders of such series; and provided,
further, 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
Securityholders of such series shall be given until at least 90 days after the
occurrence thereof. For the purpose of this Section, the term "default", with
respect to Securities of any series, 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. Except as otherwise provided in
Section 601:

                 (a) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;
<PAGE>   53
                                       44


                 (b) 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;

                 (c) 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;

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

                 (e) 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 Securityholders pursuant to this Indenture,
         unless such Securityholders 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;

                 (f) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, 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;

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

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


         SECTION 604. Not Responsible for Recitals or Issuance of Securities.
The recitals contained herein and in the Securities, except the certificates of
authentication, shall be taken as the statements of the Company, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no repre-

                                       45


sentations as to the validity or sufficiency of this Indenture or of the 
Securities. The Trustee shall not be accountable for the use or application 
by the Company of Securities or the proceeds thereof.


         SECTION 605. May Hold Securities. The Trustee, any Paying Agent, the
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, Paying Agent, Security Registrar or such
other agent.


         SECTION 606. Money Held in Trust. Subject to the provisions of Section
1003 hereof, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
law. The Trustee shall be under no liability for interest on any money received
by it hereunder except as otherwise agreed in writing with the Company.


         SECTION 607. Compensation and Reimbursement. The Company agrees

                 (1) to pay to the Trustee from time to time such compensation
         as the Company and the Trustee shall from time to time agree 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 reasonable expenses, disbursements
         and advances incurred or made by the Trustee in accordance with any
         provision of this Indenture (including the reasonable compensation and
         the expenses and disbursements of its agents and counsel), except any
         such expense, disbursement or advance as may be attributable to its
         negligence or bad faith; and

                 (3) to indemnify each of the Trustee or any predecessor Trustee
         for, and to hold it harmless against, any and all losses, damages,
         claims, liabilities or expenses, including taxes (other than taxes
         based upon, measured by, or determined by 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 this trust,
         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.


         As security for the performance of the obligations of the Company under
this Section the Trustee shall have a claim prior to the Securities upon all
<PAGE>   55
                                       46


property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
particular Securities.


         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.


         The provisions of this Section shall survive the termination of this
Indenture.


         SECTION 608. Disqualification; Conflicting Interests. The Trustee for
the Securities of any series issued hereunder shall be subject to the provisions
of Section 310(b) of the Trust Indenture Act during the period of time provided
for therein. In determining whether the Trustee has a conflicting interest as
defined in Section 310(b) of the Trust Indenture Act with respect to the
Securities of any series, there shall be excluded this Indenture with respect to
Securities of any particular series of Securities other than that series.
Nothing herein shall prevent the Trustee from filing with the Commission the
application referred to in the second to last paragraph of Section 310(b) of the
Trust Indenture Act.


         SECTION 609. Corporate Trustee Required; Eligibility. There shall at
all times be a Trustee hereunder with respect to each series of Securities,
which shall be either

                 (i) a corporation organized and doing business under the laws
         of the United States of America or of any State, authorized under such
         laws to exercise corporate trust powers and subject to supervision or
         examination by Federal or State authority, or

                 (ii) a corporation or other Person organized and doing business
         under the laws of a foreign government that is permitted to act as
         Trustee pursuant to a rule, regulation or order of the Commission,
         authorized under such laws to exercise corporate trust powers, and
         subject to supervision or examination by authority of such foreign
         government or a political subdivision thereof substantially equivalent
         to supervision or examination applicable to United States institutional
         trustees,
<PAGE>   56
                                       47


in either case having a combined capital and surplus of at least $50,000,000. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. Neither the Company nor any
person directly or indirectly controlling, controlled by, or under common
control with the Company shall serve as trustee for the Securities of any series
issued hereunder. If at any time the Trustee with respect to any series of
Securities shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect specified
in Section 610.


         SECTION 610. Resignation and Removal; Appointment of Successor. (a) 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 under Section 611.


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


         (c) The Trustee may be removed with respect to any series of Securities
at any time by Act of the Holders of a majority in principal amount of the
Outstanding Securities of that series, delivered to the Trustee and to the
Company. If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
removal, the Trustee subject to removal may petition any court of competent
jurisdiction for the appointment of a successor Trustee.


         (d) If at any time:

                 (1) the Trustee shall fail to comply with Section 310(b) of the
         Trust Indenture Act pursuant to Section 608 with respect to any series
         of Securities after written request therefor by the Company or by any
         Securityholder who has been a bona fide Holder of a Security of that
         series for at least 6 months, or
<PAGE>   57
                                       48


                 (2) the Trustee shall cease to be eligible under Section 609
         with respect to any series of Securities and shall fail to resign after
         written request therefor by the Company or by any such Securityholder,
         or

                 (3) the Trustee shall become incapable of acting with respect
         to any series of Securities, or

                 (4) the Trustee 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 the series, or in the case of Clause (4), with respect
to all series, or (ii) subject to Section 514, any Securityholder who has been a
bona fide Holder of a Security of such series for at least 6 months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee with respect to the series, or, in the case of Clause (4),
with respect to all series.


         (e) If the Trustee shall resign, be removed or become incapable of
acting with respect to any series of Securities, or if a vacancy shall occur in
the office of the Trustee with respect to any series of Securities for any
cause, the Company, by a Board Resolution, shall promptly appoint a successor
Trustee for that series of Securities. If, within one year after such
resignation, removal or incapacity, or the occurrence of such vacancy, a
successor Trustee with respect to such series of Securities 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, become the successor Trustee with respect to such series and
supersede the successor Trustee appointed by the Company with respect to such
series. If no successor Trustee with respect to such series shall have been so
appointed by the Company or the Securityholders of such series and accepted
appointment in the manner hereinafter provided, subject to Section 514, any
Securityholder who has been a bona fide Holder of a Security of that series for
at least 6 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 such series.
<PAGE>   58
                                       49


                 (f) The Company shall give notice of each resignation and each
         removal of the Trustee with respect to any series and each appointment
         of a successor Trustee with respect to any series by mailing written
         notice of such event by first-class mail, postage prepaid, to the
         Holders of Securities of that series as their names and addresses
         appear in the Security Register. Each notice shall include the name of
         the successor Trustee and the address of its principal Corporate Trust
         Office.


         SECTION 611. Acceptance of Appointment by Successor. Every successor
Trustee appointed hereunder shall execute, acknowledge and deliver to the
Company and to the predecessor Trustee an instrument accepting such appointment,
and thereupon the resignation or removal of the predecessor Trustee shall become
effective with respect to any series as to which it is resigning or being
removed as Trustee, and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the predecessor Trustee with respect to any such series; but, on request of
the Company or the successor Trustee, such predecessor Trustee shall, upon
payment of its reasonable charges, if any, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
predecessor Trustee, and shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such predecessor Trustee
hereunder with respect to all or any such series, subject nevertheless to its
lien, if any, provided for in Section 607. 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.


         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
predecessor Trustee and each successor Trustee with respect to the Securities of
any applicable series shall execute and deliver an indenture supplemental hereto
which shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the predecessor
Trustee with respect to the Securities of any series as to which the predecessor
Trustee is not being succeeded shall continue to be vested in the predecessor
Trustee, and 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
<PAGE>   59
                                       50


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.


         No successor Trustee with respect to any series of Securities shall
accept its appointment unless at the time of such acceptance such successor
Trustee shall be qualified and eligible with respect to that series 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 of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. 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. (a)
Subject to Subsection (b) of this Section, if the Trustee shall be or shall
become a creditor, directly or indirectly, secured or unsecured, of the Company
within 3 months prior to a default, as defined in Subsection (c) of this
Section, or subsequent to such a default, then, unless and until such default
shall be cured, the Trustee shall set apart and hold in a special account for
the benefit of the Trustee individually, the Holders of the Securities and the
holders of other indenture securities (as defined in Subsection (c) of this
Section):

                 (1) an amount equal to any and all reduction in the amount due
         and owing upon any claim as such creditor in respect of principal or
         interest, effected after the beginning of such 3-month period and valid
         as against the Company and its other creditors, except any such
         reduction resulting from the receipt or disposition of any property
         described in paragraph (2) of this Subsection, or from the exercise of
         any right of set-off which the Trustee could have exercised if a
         petition in bankruptcy had been filed by or against the Company upon
         the date of such default; and

                 (2) all property received by the Trustee in respect of any
         claim as such creditor, either as security therefor, or in satisfaction
         or composition
<PAGE>   60
                                       51


thereof, or otherwise, after the beginning of such 3-month period, or an amount
equal to the proceeds of any such property, if disposed of, subject, however, to
the rights, if any, of the Company and its other creditors in such property or
such proceeds.


Nothing herein contained, however, shall affect the right of the Trustee

                 (A) to retain for its own account (i) payments made on account
         of any such claim by any Person (other than the Company) who is liable
         thereon, and (ii) the proceeds of the bona fide sale of any such claim
         by the Trustee to a third person, and (iii) distributions made in cash,
         securities or other property in respect of claims filed against the
         Company in bankruptcy or receivership or in proceedings for
         reorganization pursuant to the Federal Bankruptcy Act or applicable
         State law;

                 (B) to realize, for its own account, upon any property held by
         it as security for any such claim, if such property was so held prior
         to the beginning of such 3-month period;

                 (C) to realize, for its own account, but only to the extent of
         the claim hereinafter mentioned, upon any property held by it as
         security for any such claim, if such claim was created after the
         beginning of such 3-month period and such property was received as
         security therefor simultaneously with the creation thereof, and if the
         Trustee shall sustain the burden of proving that at the time such
         property was so received the Trustee had no reasonable cause to believe
         that a default as defined in Subsection (c) of this Section would occur
         within 3 months; or

                 (D) to receive payment on any claim referred to in paragraph
         (B) or against the release of any property held as security for such
         claim as provided in paragraph (B) or (C), as the case may be, to the
         extent of the fair value of such property.


         For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such 3-month period for property held as security at the
time of such substitution shall, to the extent of the fair value of the property
released, have the same status as the property released, and, to the extent that
any claim referred to in any of such paragraphs is created in renewal of or in
substitution for or for the purpose of repaying or refunding any pre-existing
claim of the Trustee as such creditor, such claim shall have the same status as
such pre-existing claim.


         If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned
between the Trustee, the Securityholders and the holders of other indenture
securities in such manner that the Trustee, the Securityholders and the holders
of other
<PAGE>   61
                                       52


indenture securities realize, as a result of payments from such special account
and payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee anything on account
of the receipt by it from the Company of the funds and property in such special
account and before crediting to the respective claims of the Trustee and the
Securityholders and the holders of other indenture securities dividends on
claims filed against the Company in bankruptcy or receivership or in proceedings
for reorganization pursuant to the Federal Bankruptcy Act or applicable State
law, but after crediting thereon receipts on account of the indebtedness
represented by their respective claims from all sources other than from such
dividends and from the funds and property so held in such special account. As
used in this paragraph, with respect to any claim, the term "dividends" shall
include any distribution with respect to such claim, in bankruptcy or
receivership or proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law, whether such distribution is made in
cash, securities, or other property, but shall not include any such distribution
with respect to the secured portion, if any, of such claim. The court in which
such bankruptcy, receivership or proceedings for reorganization is pending shall
have jurisdiction (i) to apportion between the Trustee and the Securityholders
and the holders of other indenture securities, in accordance with the provisions
of this paragraph, the funds and property held in such special account and
proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to
give to the provisions of this paragraph due consideration in determining the
fairness of the distributions to be made to the Trustee and the Securityholders
and the holders of other indenture securities with respect to their respective
claims, in which event it shall not be necessary to liquidate or to appraise the
value of any securities or other property held in such special account or as
security for any such claim, or to make a specific allocation of such
distributions as between the secured and unsecured portions of such claims, or
otherwise to apply the provisions of this paragraph as a mathematical formula.


         Any Trustee which has resigned or been removed after the beginning of
such 3-month period shall be subject to the provisions of this Subsection as
though such resignation or removal had not occurred. If any Trustee has resigned
or been removed prior to the beginning of such 3-month period, it
<PAGE>   62
                                       53


shall be subject to the provisions of this Subsection if and only if the
following conditions exist:

                 (i) the receipt of property or reduction of claim, which would
         have given rise to the obligation to account, if such Trustee had
         continued as Trustee, occurred after the beginning of such 3-month
         period; and

                 (ii) such receipt of property or reduction of claim occurred
         within 3 months after such resignation or removal.


        (b) There shall be excluded from the operation of Subsection (a) of this
Section a creditor relationship arising from 

                 (1) the ownership or acquisition of securities issued under any
         indenture, or any security or securities having a maturity of one year
         or more at the time of acquisition by the Trustee;

                (2) advances authorized by a receivership or bankruptcy court of
        competent jurisdiction, or by this Indenture, for the purpose of
        preserving any property which shall at any time be subject to the lien
        of this Indenture or of discharging tax liens or other prior liens or
        encumbrances thereon, if notice of such advances and of the
        circumstances surrounding the making thereof is given to the
        Securityholders at the time and in the manner provided in this
        Indenture;  

                 (3) disbursements made in the ordinary course of business in
         the capacity of trustee under an indenture, transfer agent, registrar,
         custodian, paying agent, fiscal agent or depository, or other similar
         capacity;

                 (4) an indebtedness created as a result of services rendered or
         premises rented; or an indebtedness created as a result of goods or
         securities sold in a cash transaction as defined in Subsection (c) of
         this Section;

                 (5) the ownership of stock or of other securities of a
         corporation organized under the provisions of Section 25(a) of the
         Federal Reserve Act, as amended, which is directly or indirectly a
         creditor of the Company; or

                 (6) the acquisition, ownership, acceptance or negotiation of
         any drafts, bills of exchange, acceptances or obligations which fall
         within the classification of self-liquidating paper as defined in
         Subsection (c) of this Section.


         (c) For the purposes of this Section only:

                 (1) The term "default" means any failure to make payment in
         full of the principal of or interest on any of the Securities or upon
         the other indenture securities when and as such principal or interest
         becomes due and payable.
<PAGE>   63
                                       54


                 (2) The term "other indenture securities" means securities upon
         which the Company is an obligor outstanding under any other indenture
         (i) under which the Trustee is also trustee, (ii) which contains
         provisions substantially similar to the provisions of this Section, and
         (iii) under which a default exists at the time of the apportionment of
         the funds and property held in such special account.

                 (3) The term "cash transaction" means any transaction in which
         full payment for goods or securities sold is made within 7 days after
         delivery of the goods or securities in currency or in checks or other
         orders drawn upon banks or bankers and payable upon demand.

                 (4) The term "self-liquidating paper" means any draft, bill of
         exchange, acceptance or obligation which is made, drawn, negotiated or
         incurred by the Company for the purpose of financing the purchase,
         processing, manufacturing, shipment, storage or sale of goods, wares or
         merchandise and which is secured by documents evidencing title to,
         possession of, or a lien upon, the goods, wares or merchandise or the
         receivables or proceeds arising from the sale of the goods, wares or
         merchandise previously constituting the security, provided the security
         is received by the Trustee simultaneously with the creation of the
         creditor relationship with the Company arising from the making,
         drawing, negotiating or incurring of the draft, bill of exchange,
         acceptance or obligation.

                 (5) The term "Company" means any obligor upon the Securities.


         SECTION 614. Appointment of Authenticating Agent. At any time when any
of the Securities remain Outstanding the Trustee, with the approval of the
Company, 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 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 an Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and,
if
<PAGE>   64
                                       55


other than the Company itself, 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.


         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and, if other than the Company, 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, if other than
the Company, 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,
with the approval of the Company, 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 alternate
certificate of authentication in the following form:


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

                     SECURITYHOLDERS' LISTS AND REPORTS BY

                              TRUSTEE AND COMPANY


         SECTION 701. Company To Furnish Trustee Names and Addresses of
Securityholders. The Company will furnish or cause to be furnished to the
Trustee

                 (1) semi-annually, not later than December 1 and June 1 in each
         year in such form as the Trustee may reasonably require, a list of the
         names and addresses of the Holders of Securities of each series as of a
         date not more than 15 days prior to the date such list is furnished,
         and

                 (2) at such other times as the Trustee may request in writing,
         within 30 days after the receipt by the Company of any such request, a
         list of similar form and content as of a date not more than 15 days
         prior to the date such list is furnished,


excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.
<PAGE>   66
                                       57




         SECTION 702. Preservation of Information; Communications to
Securityholders. (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders of Securities
contained in the most recent list furnished to the Trustee as provided in
Section 701 and the names and addresses of Holders of Securities received by the
Trustee in its capacity as Security Registrar. The Trustee may destroy any list
furnished to it as provided in Section 701 upon receipt of a new list so
furnished.

         (b) If 3 or more Holders of Securities of any series (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a Security of such
series for a period of at least 6 months preceding the date of such application,
and such application states that the applicants desire to communicate with other
Holders of Securities of such series or with the Holders of all Securities with
respect to their rights under this Indenture or under such Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within 5 Business Days
after the receipt of such application, at its election, either

                 (i) afford such applicants access to the information preserved
         at the time by the Trustee in accordance with Section 702(a), or

                 (ii) inform such applicants as to the approximate number of
         Holders of Securities of such series or all Securities, as the case may
         be, whose names and addresses appear in the information preserved at
         the time by the Trustee in accordance with Section 702(a), and as to
         the approximate cost of mailing to such Securityholders the form of
         proxy or other communication, if any, specified in such application.


         If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of a Security of such series or to all Securityholders, as
the case may be, whose names and addresses appear in the information preserved
at the time by the Trustee in accordance with Section 702(a), a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless, within 5 days after such tender, the Trustee shall mail to such
applicants and file with the Commission, together with a copy of the material to
be mailed, a written statement to the effect that, in the opinion
<PAGE>   67
                                       58


of the Trustee, such mailing would be contrary to the best interests of the
Holders of Securities of such series or all Securityholders, as the case may be,
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all Securityholders of such series or all
Securityholders, as the case may be, with reasonable promptness after the entry
of such order and the renewal of such tender, otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.


         (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders of Securities in accordance with
Section 702(b), regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Section 702(b).

         SECTION 703. Reports by Trustee. (a) The term "reporting date" as used
in this Section means May 15. Within 60 days after the reporting date in each
year, beginning in 1992, the Trustee shall transmit by mail to all
Securityholders, as their names and addresses appear in the Security Register, a
brief report dated as of such reporting date with respect to any of the
following events which may have occurred during the twelve months preceding the
date of such report (but if no such event has occurred within such period, no
report need be transmitted):

                 (1) any change to its eligibility under Section 609 and its
         qualifications under Section 608;

                 (2) the creation of or any material change to a relationship
         specified in Section 310(b)(1) through Section 310(b)(10) of the Trust
         Indenture Act;

                 (3) the character and amount of any advances (and if the
         Trustee elects so to state, the circumstances surrounding the making
         thereof) made by the Trustee (as such) which remain unpaid on the date
         of such report, and for the reimbursement of which it claims or may
         claim a lien
<PAGE>   68
                                       59


or charge, prior to that of Securities of any series, on any property or funds
held or collected by it as Trustee, except that the Trustee shall not be
required (but may elect) to report such advances if such advances so remaining
unpaid aggregate not more than 1/2 of 1% of the principal amount of the
Securities of such series Outstanding on the date of such report;

                 (4) any change to the amount, interest rate and maturity date
         of all other indebtedness owing by the Company (or by any other obligor
         on the Securities) to the Trustee in its individual capacity, on the
         date of such report, with a brief description of any property held as
         collateral security therefor, except an indebtedness based upon a
         creditor relationship arising in any manner described in Section
         613(b)(2), (3), (4), or (6);

                 (5) any change to the property and funds, if any, physically in
         the possession of the Trustee as such on the date of such report;

                 (6) any additional issue of Securities which the Trustee has
         not previously reported; and

                 (7) any action taken by the Trustee in the performance of its
         duties hereunder which it has not previously reported and which in its
         opinion materially affects the Securities, except action in respect of
         a default, notice of which has been or is to be withheld by the Trustee
         in accordance with Section 602.


         (b) The Trustee shall transmit by mail to all Securityholders, as their
names and addresses appear in the Security Register, a brief report with respect
to the character and amount of any advances (and if the Trustee elects so to
state, the circumstances surrounding the making thereof) made by the Trustee (as
such) since the date of the last report transmitted pursuant to Subsection (a)
of this Section (or if no such report has yet been so transmitted, since the
date of execution of this instrument) for the reimbursement of which it claims
or may claim a lien or charge, prior to that of the Securities of any series, on
property or funds held or collected by it as Trustee, and which it has not
previously reported pursuant to this Subsection, except that the Trustee shall
not be required (but may elect) to report such advances if such advances
remaining unpaid at any time aggregate 10% or less of the principal amount of
the Securities Outstanding of such series at such time, such report to be
transmitted within 90 days after such time.


         (c) A copy of each such report shall, at the time of such transmission
to Securityholders, be furnished to the Company and be filed by the Trustee with
each stock exchange upon which the Securities are listed, and also with the
<PAGE>   69
                                       60


Commission.  The Company will promptly notify the Trustee when the Securities
are listed on any stock exchange.


         SECTION 704.  Reports by Company.  The Company will

                 (1) file with the Trustee, within 15 days after the Company is
         required to file the same with the Commission, copies of the annual
         reports and of the information, documents and other reports (or copies
         of such portions of any of the foregoing as the Commission may from
         time to time by rules and regulations prescribe) which the Company may
         be required to file with the Commission pursuant to Section 13 or
         Section 15(d) of the Securities Exchange Act of 1934, or, if the
         Company is not required to file information, documents or reports
         pursuant to either of said Sections, then it will file with the Trustee
         and the Commission, in accordance with rules and regulations prescribed
         from time to time by the Commission, such of the supplementary and
         periodic information, documents and reports which may be required
         pursuant to Section 13 of the Securities Exchange Act of 1934 in
         respect of a security listed and registered on a national securities
         exchange as may be prescribed from time to time in such rules and
         regulations;

                 (2) file with the Trustee and the Commission, in accordance
         with rules and regulations prescribed from time to time by the
         Commission, such additional information, documents and reports with
         respect to compliance by the Company with the conditions and covenants
         of this Indenture as may be required from time to time by such rules
         and regulations; and

                 (3) transmit by mail to all Securityholders, as their names and
         addresses appear in the Security Register, within 30 days after the
         filing thereof with the Trustee, such summaries of any information,
         documents and reports required to be filed by the Company pursuant to
         paragraphs (1) and (2) of this Section as may be required by rules and
         regulations prescribed from time to time by the Commission.

                                 ARTICLE EIGHT

                 CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER


         SECTION 801. When Company May Merge or Transfer Assets. The Company, in
a single transaction or through a series of related transactions, shall not
consolidate with or merge with or into any other Person or transfer (by lease,
assignment, sale or otherwise) all or substantially all of its properties and
assets to another Person or group of affiliated Persons, unless:

                 (a) either (1) the Company shall be the continuing corporation
         or (2) the Person (if other than the Company) formed by such
         consolidation or into which the Company is merged or to which all or
         substantially all of the properties and assets of the Company are
         transferred (i) shall be a corporation, partnership or trust organized
         and validly existing under the laws of the United States or any State
         thereof or the District of Columbia and (ii) shall expressly assume, by
         an indenture supplemental hereto, executed and delivered to the
         Trustee, in form satisfactory to the Trustee, all of the obligations of
         the Company under the Securities and this Indenture and the performance
         of every covenant of this Indenture on the part of the Company to be
         performed or observed;

                 (b) immediately after giving effect to such transaction, and
         the assumption contemplated by clause (a) above, no Event of Default,
         and no event which, after notice or lapse of time, or both, would
         become an Event of Default, shall have occurred and be continuing; and

                 (c) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger or transfer and, if a supplemental indenture is
         required in connection with such transaction, such supplemental
         indenture, comply with this Article 8 and that all conditions precedent
         herein provided for relating to such transaction have been satisfied.


         For purposes of the foregoing, the transfer (by lease, assignment,
sale or otherwise) of the properties and assets of one or more Subsidiaries
(other than to the Company or another wholly owned Subsidiary), which, if such
assets were owned by the Company, would constitute all or substantially all of
the properties and assets of the Company, shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company.


         The successor Person formed by such consolidation or into which the
Company is merged or the successor Person to which such conveyance, transfer or
lease is made shall succeed to, and be substituted for, and may exercise
<PAGE>   71
                                       62


every right and power of, the Company under this Indenture with the same effect
as if such successor had been named as the Company herein, and thereafter,
except in the case of a lease of its properties and assets substantially as an
entirety, the Company shall be discharged and released from all obligations and
covenants under this Indenture and the Securities. The Trustee shall enter into
a supplemental indenture to evidence the succession and substitution of such
successor Person and such discharge and release of the Company.


                                  ARTICLE NINE

                            SUPPLEMENTAL INDENTURES


         SECTION 901. Supplemental Indentures Without Consent of
Securityholders.  Without the consent of the Holders of any Securities, the
Company, when authorized by a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

                 (1) to evidence the succession of another corporation to the
         Company, and the assumption by any such successor of the covenants of
         the Company herein and in the Securities contained; or

                 (2) to add to the covenants of the Company, or to surrender any
         right or power herein conferred upon the Company, for the benefit of
         the Holders of the Securities of any or all series (and if such
         covenants or the surrender of such right or power are to be for the
         benefit of less than all series of Securities, stating that such
         covenants are expressly being included or such surrenders are expressly
         being made solely for the benefit of one or more specified series); or

                 (3) to cure any ambiguity, to correct or supplement any
         provision herein which may be inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Indenture; or

                 (4) to add to this Indenture such provisions as may be
         expressly permitted by the TIA, excluding, however, the provisions
         referred to in Section 316(a)(2) of the TIA as in effect at the date as
         of which this instrument was executed or any corresponding provision in
         any similar Federal statute hereafter enacted; or

                 (5) to establish any form of Security, as provided in Article
         Two, and to provide for the issuance of any series of Securities as
         provided in Article Three and to set forth the terms thereof, and/or to
         add to the rights of the Holders of the Securities of any series; or
<PAGE>   72
                                       63


                 (6) to evidence and provide for the acceptance of appointment
         by another corporation as a successor Trustee hereunder with respect to
         one or more series of Securities and to 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, pursuant to Section 611; or,

                 (7) to add any additional Events of Default in respect of the
         Securities of any or all series (and if such additional Events of
         Default are to be in respect of less than all series of Securities,
         stating that such Events of Default are expressly being included solely
         for the benefit of one or more specified series); or

                 (8) to provide for the issuance of Securities in coupon as well
         as fully registered form.


         No supplemental indenture for the purposes identified in Clauses (2),
(3), (5) or (7) above may be entered into if to do so would adversely affect
the interest of the Holders of Securities of any series.


         SECTION 902. Supplemental Indentures with Consent of Securityholders.
With the consent of the Holders of not less than a majority in principal amount
of the Outstanding Securities of each series affected by such supplemental
indenture or indentures, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of the Securities of each such series under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Security affected thereby,

                 (1) change the Maturity of the principal of, or the Stated
         Maturity of any premium on, or any installment of interest on, any
         Security, or reduce the principal amount thereof or the interest or any
         premium thereon, or change the method of computing the amount of
         principal thereof or interest thereon on any date or change any Place
         of Payment where any Security or any premium or interest thereon is
         payable, or impair the right to institute suit for the enforcement of
         any such payment on or after the Maturity or the Stated Maturity, as
         the case may be, thereof (or, in the case of redemption or repayment,
         on or after the Redemption Date or the Repayment Date, as the case may
         be); or

                 (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any
<PAGE>   73
                                       64


         such supplemental indenture, or the consent of whose Holders is
         required for any waiver of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences,
         provided for in this Indenture; or

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

         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.

         It shall not be necessary for any Act of Securityholders 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.

         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.


         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.

                                       65


         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

         SECTION 906. Reference in Securities to Supplemental Indentures.

                                  ARTICLE TEN

                                   COVENANTS

         SECTION 1001. Payment of Principal, Premium and Interest. With respect
to each series of Securities, the Company will duly and punctually pay the
principal of (and premium, if any) and interest on such Securities in accordance
with their terms and this Indenture, and will duly comply with all the other
terms, agreements and conditions contained in, or made in the Indenture for the
benefit of, the Securities of such series.


         SECTION 1002. Maintenance of Office or Agency. The Company will
maintain an office or agency in each Place of Payment where Securities may be
presented or surrendered for payment, where Securities may be surrendered for
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and of any change in
the location, of such office or agency. If at any time the Company shall fail to
maintain such office or agency or shall fail to furnish the Trustee
<PAGE>   75
                                       66


with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the principal Corporate Trust Office of the Trustee,
Attention: Corporate Trust Trustee Administration, and the Company hereby
appoints the Trustee its agent to receive all such presentations, surrenders,
notices and demands.


         SECTION 1003.  Money for Security Payments to be Held in Trust.  If
the Company shall at any time act as its own Paying Agent for any series of
Securities, it will, on or before each due date of the principal of (and
premium, if any) or interest on, any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal (and premium, if any) or 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 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 (and
premium, if any) or interest on, any Securities of such series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal (and premium, if any) or interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.


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

                 (1) hold all sums held by it for the payment of principal of
         (and premium, if any) or interest on Securities of such series in trust
         for the benefit of the Persons entitled thereto until such sums shall
         be paid to such Persons or otherwise disposed of as herein provided;

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

                 (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.
<PAGE>   76
                                       67


         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture with respect to any series of
Securities 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 in respect of each and every series of Securities as to which it
seeks to discharge this Indenture or, if for any other purpose, all sums so
held in trust by the Company in respect of all Securities, 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 (and premium, if
any) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium, if any) 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.  The Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company mail to the Holders of the Securities as to which the money to be
repaid was held in trust, as their names and addresses appear in the Security
Register, a notice that such moneys remain unclaimed and that, after a date
specified in the notice, which shall not be less than 30 days from the date on
which the notice was first mailed to the Holders of the Securities as to which
the money to be repaid was held in trust, any unclaimed balance of such moneys
then remaining will be paid to the Company free of the trust formerly impressed
upon it.


         SECTION 1004. Statement as to Compliance. The Company will deliver to
the Trustee, within 120 days after the end of each fiscal year, a written
statement signed by the principal executive officer, principal financial officer
or principal accounting officer of the Company stating that

                 (1) a review of the activities of the Company during such year
         and of performance under this Indenture and under the terms of the
         Securities has been made under his supervision; and
<PAGE>   77
                                       68


                 (2) to the best of his knowledge, based on such review, the
         Company has fulfilled all its obligations under this Indenture and has
         complied with all conditions and covenants on its part contained in
         this Indenture through such year, or, if there has been a default in
         the fulfillment of any such obligation, covenant or condition,
         specifying each such default known to him and the nature and status
         thereof.


         For the purpose of this Section 1004, default and compliance shall be
determined without regard to any grace period or requirement of notice provided
pursuant to the terms of this Indenture.


         SECTION 1005. Legal Existence. Subject to Article Eight the Company
will do or cause to be done all things necessary to preserve and keep in full
force and effect its legal existence.


         SECTION 1006. Limitation on Liens. The Company shall not create, assume
or suffer to exist any Lien upon Restricted Property to secure any debt of the
Company, any Subsidiary or any other person, or permit any Subsidiary so to do,
without making effective provision whereby the Securities then outstanding and
having the benefit of this Section shall be secured by the Lien equally and
ratably with such debt for so long as such debt shall be so secured, except that
the foregoing shall not prevent the Company or any Subsidiary from creating,
assuming or suffering to exist Liens of the following character:

                 (1) with respect to any series of Securities any Lien existing
         on the date of issuance of the series;

                 (2) any Lien existing on property owned or leased by a
         corporation at the time it becomes a Subsidiary;

                 (3) any Lien existing on property at the time of the
         acquisition thereof by the Company or a Subsidiary;

                 (4) any Lien to secure any debt incurred prior to, at the time
         of, or within 12 months after the acquisition of Restricted Property
         for the purpose of financing all or any part of the purchase price
         thereof and any Lien to the extent that it secures debt which is in
         excess of such purchase price and for the payment of which recourse may
         be had only against such Restricted Property;

                 (5) any Lien to secure any debt incurred prior to, at the time
         of, or within 12 months after the completion of the construction and
         commencement of commercial operation, alteration, repair or improvement
         of Restricted Property for the purpose of financing all or any part of
         the cost thereof and any Lien to the extent that it secures debt which
         is in excess

<PAGE>   78
                                       69


         of such cost and for the payment of which recourse may be had only 
         against such Restricted Property;

                 (6) any Lien securing debt of a Subsidiary owing to the Company
         or to another Subsidiary;

                 (7) any Lien in favor of the United States of America of any
         State thereof or any other country, or any agency, instrumentality of
         political subdivision or any or the foregoing, to secure partial,
         progress, advance or other payments or performance pursuant to the
         provisions of any contract or statute, or any Liens securing industrial
         development, pollution control, or similar revenue bonds;

                 (8) any extension, renewal or replacement (or successive
         extensions, renewals or replacements) in whole or in part of any Lien
         referred to in clauses (1) through (7) above, so long as the principal
         amount of the debt secured thereby does not exceed the principal amount
         of debt so secured at the time of the extension, renewal or replacement
         (except that, where an additional principal amount of debt is incurred
         to provide funds for the completion of a specific project, the
         additional principal amount, and any related financing costs, may be
         secured by the Lien as well) and the Lien is limited to the same
         property subject to the Lien so extended, renewed or replaced (plus
         improvements on the property); and

                 (9) any Lien not permitted by clauses (1) through (8) above
         securing debt which, together with the aggregate outstanding principal
         amount of all other debt of the Company and its Subsidiaries owning
         Restricted Property which would otherwise be subject to the foregoing
         restrictions and the aggregate Value of existing Sale and Leaseback
         Transactions which would be subject to the restrictions of Section 1007
         but for this clause (9), does not at any time exceed 10% of
         Consolidated Net Tangible Assets.


         SECTION 1007. Limitation on Sale and Leasebacks. The Company shall not
enter into any Sale and Leaseback Transaction, nor permit any Subsidiary owning
Restricted Property so to do, unless either:

                 (1) the Company or such Subsidiary would be entitled to incur
         debt, in a principal amount at least equal to the Value of such Sale
         and Leaseback Transaction, which is secured by Liens on the property to
         be leased (without equally and ratably securing the outstanding
         Securities) because such Liens would be of such character that no
         violation of any of the provisions of Section 1006 would result, or

                 (2) the Company during the six months immediately following the
         effective date of such Sale and Leaseback Transaction causes to be
         applied to (A) the acquisition of Restricted Property or (B) the
         voluntary retirement of Funded Debt (whether by redemption, defeasance,
         repurchase,
<PAGE>   79
                                       70


         or otherwise) an amount equal to the Value of such Sale and Leaseback
         Transaction.


         SECTION 1008. Waiver of Certain Covenants. Ile Company may omit in
respect of any series of Securities, in any particular instance, to comply with
any covenant or condition set forth in Sections 1006 and 1007, if before or
after the time for such compliance the Holders of at least a majority in
principal amount of the Securities at the time Outstanding of such series shall,
by Act of such Securityholders, either waive such compliance in such instance or
generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant 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 covenant or
condition shall remain in full force and effect.


                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101. Applicability of Article. The Company may reserve the
right to redeem and pay before Stated Maturity all or any part of the Securities
of any series, either by optional redemption, sinking or purchase fund or
analogous obligation or otherwise, by provision therefor in the form of Security
for such series established and approved pursuant to Section 202 and on such
terms as are specified in such form or in the indenture supplemental hereto with
respect to Securities of such series as provided in Section 301. Redemption of
Securities of any series shall be made in accordance with the terms of such
Securities and, to the extent that this Article does not conflict with such
terms, the succeeding Sections of this Article.


         SECTION 1102. Election To Redeem; Notice to Trustee. The election of
the Company to redeem any Securities redeemable at the election of the Company
shall be evidenced by, or pursuant to authority granted by, a Board Resolution.
In case of any redemption at the election of the Company of less than all of 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 and of
the principal amount of Securities of such series and the Tranche (as defined in
Section 1103) to be redeemed.
<PAGE>   80
                                       71


         In the case of any redemption of Securities (i) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (ii) pursuant to an election of
the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.


         SECTION 1103. Selection by Trustee of Securities To Be Redeemed. If
less than all the Securities of like tenor and terms of any series (a "Tranche")
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 Tranche not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate (other than pro rata
selection) and which may include provision for the election for redemption of
portions of the principal of Securities of such Tranche of a denomination larger
than the minimum authorized denomination for Securities of that series. Unless
otherwise provided in the terms of a particular series of Securities, the
portions of the principal of Securities so selected for partial redemption shall
be equal to the minimum authorized denomination of the Securities of such
series, or an integral multiple thereof, and the principal amount which remains
outstanding shall not be less than the minimum authorized denomination for
Securities of such series. If less than all the Securities of unlike tenor and
terms of a series are to be redeemed, the particular Tranche of Securities to be
redeemed shall be selected by the Company.


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


         For a purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal of such Security 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.
<PAGE>   81
                                       72


         All notices of redemption shall state:

                 (1) the Redemption Date;

                 (2) the Redemption Price;

                 (3) the CUSIP number;

                 (4) if less than all Outstanding Securities of any series are
         to be redeemed, the identification (and, in the case of partial
         redemption, the respective principal amounts) of the Securities to be
         redeemed, from the Holder to whom the notice is given;

                 (5) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security, and that interest, if
         any, thereon shall cease to accrue from and after said date;

                 (6) the place where such Securities are to be surrendered for
         payment of the Redemption Price, which shall be the office or agency of
         the Company in the Place of Payment; and

                 (7) that the redemption is on account of a sinking or purchase
         fund, or other analogous obligation, if that be the case.


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


         SECTION 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with 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 all the Securities which are to be redeemed on that date;
provided that such amount shall be so deposited with the Trustee or Paying Agent
in time for the Trustee or Paying Agent, as the case may be, to pay such
Redemption Price in accordance with its normal procedures.


         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) such Securities shall cease to bear
interest. Upon surrender of such Securities for redemption in accordance with
the notice, such Securities shall be paid by the Company at the Redemption
Price. Unless otherwise provided with respect to such Securities pursuant
<PAGE>   82
                                       73


to Section 301, installments of interest the Stated Maturity of which is on or
prior to the Redemption Date shall be payable to the Holders of such Securities
registered as such on the relevant Regular 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 shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security, or as
otherwise provided in such Security.

         SECTION 1107. Securities Redeemed in Part. Any Security which is to be
redeemed only in part shall be surrendered at the office or agency of the
Company in the Place of Payment with respect to that series (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 make available for
delivery to the Holder of such Security without service charge, a new Security
or Securities of the same series and Stated Maturity and of like tenor and
terms, 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.

         SECTION 1108. Provisions with Respect to any Sinking Funds. Unless the
form or terms of any series of Securities shall provide otherwise, in lieu of
making all or any part of any mandatory sinking fund payment with respect to
such series of Securities in cash, the Company may at its option (1) deliver to
the Trustee for cancellation any Securities of such series theretofore acquired
by the Company, or (2) receive credit for any Securities of such series (not
previously so credited) acquired by the Company (including by way of optional
redemption (pursuant to the sinking fund or otherwise) but not by way of
mandatory sinking fund redemption) and theretofore delivered to the Trustee for
cancellation, and if it does so then (i) Securities so delivered or credited
shall be credited at the applicable sinking fund Redemption Price with respect
to Securities of such series, and (ii) on or before the 60th day next preceding
each sinking fund Redemption Date with respect to such series of Securities, the
Company will deliver to the Trustee (A) an Officers' Certificate specifying the
portions of such sinking fund payment to be satisfied by payment of cash and by
delivery or credit of Securities of such series acquired by
<PAGE>   83
                                       74


the Company, and (B) such Securities, to the extent not previously surrendered.
Such Officers' Certificate shall also state the basis for such credit and that
the Securities for which the Company elects to receive credit have not been
previously so credited and were not acquired by the Company through operation
of the mandatory sinking fund, if any, provided with respect to such Securities
and shall also state that no Event of Default with respect to Securities of
such series has occurred and is continuing.  All Securities so delivered to the
Trustee shall be canceled by the Trustee and no Securities shall be
authenticated in lieu thereof.

         If the sinking fund payment or payments (mandatory or optional) with
respect to any series of Securities made in cash plus any unused balance of any
preceding sinking fund payments with respect to Securities of such series made
in cash shall exceed $50,000 (or a lesser sum if the Company shall so request),
unless otherwise provided by the terms of such series of Securities, that cash
shall be applied by the Trustee on the sinking fund Redemption Date with respect
to Securities of such series next following the date of such payment to the
redemption of Securities of such series at the applicable sinking fund
Redemption Price with respect to Securities of such series, together with
accrued interest, if any, to the date fixed for redemption, with the effect
provided in Section 1106. The Trustee shall select, in the manner provided in
Section 1103, for redemption on such sinking fund Redemption Date a sufficient
principal amount of Securities of such series to utilize that cash and shall
thereupon cause notice of redemption of the Securities of such series for the
sinking fund to be given in the manner provided in Section 1104 (and with the
effect provided in Section 1106) for the redemption of Securities in part at the
option of the Company. Any sinking fund moneys not so applied or allocated by
the Trustee to the redemption of Securities of such series shall be added to the
next cash sinking fund payment with respect to Securities of such series
received by the Trustee and, together with such payment, shall be applied in
accordance with the provisions of this Section 1108. Any and all sinking fund
moneys with respect to Securities of any series held by the Trustee at the
Maturity of Securities of such series, and not held for the payment or
redemption of particular Securities of such series, shall be applied by the
Trustee, together with other moneys, if necessary, to be deposited sufficient
for the purpose, to the payment of the principal of the Securities of such
series at Maturity.

         On or before each sinking fund Redemption Date provided with respect to
Securities of any series, the Company shall deposit with the Trustee cash in
<PAGE>   84
                                       75




a sum equal to all accrued interest, if any, to the date fixed for redemption on
Securities to be redeemed on such sinking fund Redemption Date pursuant to this
Section 1108; provided that such cash shall be so deposited with the Trustee in
time for the Trustee to make the payment of such accrued interest in accordance
with its normal procedures.


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

                              [REVERSE OF SECURITY]

                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under a Senior Indenture, dated as of December 15, 1991 (herein
called the "Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and The Bank of New York, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series designated on the face hereof, limited in
aggregate principal amount to $300,000,000.

                  The Securities of this series are subject to redemption upon
not less than 30 days' notice by mail, in whole or in part, at the option of the
Company at any time at a Redemption Price equal to the greater of (i) 100% of
the principal amount of the Securities so redeemed or (ii) as determined by an
Independent Investment Banker, the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the
redemption date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case, accrued
interest thereon to the Redemption Date.

                  "Adjusted Treasury Rate" means, with respect to any Redemption
Date, the rate per annum equal to the semiannual equivalent yield to maturity of
the Comparable Treasury Issue, assuming a price for the Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such Redemption Date, plus 0.10%.

                  "Comparable Treasury Issue" means the United States Treasury
security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term of the Security to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such Security. "Independent Investment Banker"
means one of the Reference Treasury Dealers appointed by the Trustee after
consultation with the Company.

                  "Comparable Treasury Price" means, with respect to any
Redemption Date, (i) the average of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
on the third Business Day preceding such Redemption Date, as set forth in the
daily statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such Business Day, (A) the
Reference Treasury Dealer Quotations for such Redemption Date, after excluding
the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the
Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the
average of all such Quotations. "Reference Treasury Dealer Quotations" means,
with respect to each Reference Treasury Dealer and any Redemption Date, the
average, as determined by the Trustee, of the bid and asked prices for


                                       -4-
<PAGE>   90
the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Trustee by such Treasury Reference
Dealer at 5:00 p.m. on the third Business Day preceding such Redemption Date.

                  "Reference Treasury Dealer" means each of Goldman, Sachs &
Co., CS First Boston Corporation, Merrill Lynch, Pierce, Fenner & Smith
Incorporated and J.P. Morgan Securities Inc. and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), the
Company shall substitute therefor another Primary Treasury Dealer.

                  In the event of redemption of this security in part only, a
new Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

                  The Indenture contains provisions for defeasance at any time
of the entire indebtedness of this Security or certain restrictive covenants
with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

                  If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities of this
series may be declared due and payable in the manner and with the effect
provided in the Indenture.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the Securities at the time Outstanding of each series to be affected. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

                  As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the


                                       -5-
<PAGE>   91
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

                  The Securities of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof. As provided in the Indenture and subject to certain limitations therein
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 transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

                  Prior to due presentment of this Security for transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

                  All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

                  THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

Date") at a price (the "Repayment Price") equal to 100% of the principal amount
thereof, together with accrued interest to March 15, 2006.

                  To exercise such right, the Holder of this Security shall
surrender this Security, at the office or agency of the Company in New York, New
York during the period beginning on January 15, 2006 and ending at 5:00 PM (New
York City time) on February 15, 2006 (or, if February 15, 2006 is not a Business
Day, the next succeeding Business Day), with the form entitled "Option to Elect
Repayment on March 15, 2006" on the reverse hereof duly completed. Any such
notice received by the Company during the period beginning on January 15, 2006
and ending at 5:00 PM (New York City time) on February 15, 2006 (or, if February
15, 2006 is not a Business Day, the next succeeding Business Day) shall be
irrevocable. If the Repayment Date falls between any Regular Record Date and the
next succeeding Interest Payment Date, this Security must be accompanied by
payment from the Holder of an amount equal to the interest thereon which the
registered Holder thereof is to receive on such Interest Payment Date. The
repayment option may be exercised by any Holder for less than the entire
principal amount of this Security, provided that the principal amount with
respect to which such right is exercised must be equal to $1,000 or an integral
multiple of $1,000. All questions as to the validity, form, eligibility
(including time of receipt) and acceptance of this Security for repayment shall
be determined by the Company, whose determination shall be final and binding.

                  Failure by the Company to repay the Debentures Due 2036 when
required as described in the preceding paragraphs will result in an Event of
Default under the Indenture.

                  The Securities of this series are subject to redemption upon
not less than 30 days' notice by mail, in whole or in part, at the option of the
Company at any time after March 15, 2006 at a Redemption Price equal to the
greater of (i) 100% of the principal amount of the Securities so redeemed or
(ii) as determined by an Independent Investment Banker, the sum of the present
values of the remaining scheduled payments of principal and interest thereon
discounted to the redemption date on a semiannual basis (assuming a 360-day


                                       -4-
<PAGE>   96
year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in
each case, accrued interest thereon to the Redemption Date.

                  "Adjusted Treasury Rate" means, with respect to any Redemption
Date, the rate per annum equal to the semiannual equivalent yield to maturity of
the Comparable Treasury Issue, assuming a price for the Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such Redemption Date, plus 0.10%.

                  "Comparable Treasury Issue" means the United States Treasury
security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term of the Security to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such Security. "Independent Investment Banker"
means one of the Reference Treasury Dealers appointed by the Trustee after
consultation with the Company.

                  "Comparable Treasury Price" means, with respect to any
Redemption Date, (i) the average of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
on the third Business Day preceding such Redemption Date, as set forth in the
daily statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such Business Day, (A) the
Reference Treasury Dealer Quotations for such Redemption Date, after excluding
the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the
Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the
average of all such Quotations. "Reference Treasury Dealer Quotations" means,
with respect to each Reference Treasury Dealer and any Redemption Date, the
average, as determined by the Trustee, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Trustee by such Treasury Reference
Dealer at 5:00 p.m. on the third Business Day preceding such Redemption Date.

                  "Reference Treasury Dealer" means each of Goldman, Sachs &
Co., CS First Boston Corporation, Merrill Lynch, Pierce, Fenner & Smith
Incorporated and J.P. Morgan Securities Inc. and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), the
Company shall substitute therefor another Primary Treasury Dealer.

                  In the event of redemption of this Security in part only, a
new Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

                  The Indenture contains provisions for defeasance at any time
after March 15, 2006 of the entire indebtedness of this Security or certain
restrictive covenants with respect to this Security, in each case upon
compliance with certain conditions set forth in the Indenture.

                  If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities of this
series may be declared due and payable in the manner and with the effect
provided in the Indenture.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the Securities at the time Outstanding of each series to be affected. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the transfer hereof or in exchange herefor or in lieu hereof, whether or
not notation of such consent or waiver is made upon this Security.

                  As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

                  The Securities of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof. As provided in the Indenture and subject to certain limitations therein
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 transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

                  Prior to due presentment of this Security for transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

Indenture shall have the meanings assigned to them in the Indenture.

CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.
