4. On April 1, 1998, the Company completed the acquisition of TASC, Inc.("TASC")
   from Primark Corporation for a preliminary purchase price of $432 million in
   cash. TASC is a leading provider of information technology and services to
   the national intelligence sector, the Department of Defense and non-defense
   and commercial customers. The acquisition has been accounted for under the
   purchase method of accounting and reflected herein based upon preliminary
   allocations of the purchase price which is subject to finalization. This
   acquisition has resulted in an increase to goodwill of approximately $365
   million, to be amortized over forty years.

5. The Company adopted Statement of Financial Accounting Standards No. 128,
   "Earnings per Share" ("SFAS 128"), in the quarter ended January 31, 1998.
   SFAS 128 replaced the previously reported primary and fully diluted earnings
   per share ("EPS") with basic and diluted EPS. Basic EPS is calculated based
   on the weighted average number of shares outstanding and diluted EPS includes
   the effects of dilutive potential common shares. EPS amounts for prior
   periods have been restated to conform to the requirements of SFAS 128.
 
   The following table sets forth the computation of basic and diluted earnings

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     The Company reported sales of $1.14 billion and $3.16 billion for the third
quarter and nine months ended April 30, 1998 compared with $1.10 billion and
$3.10 billion for the prior year's periods, respectively. Operating profit
improved to $106.8 million and $294.9 million for the third quarter and nine
months ended April 30, 1998 compared with $95.0 million and $271.2 million for
the corresponding periods of the prior fiscal year. Net earnings rose 11.5% to
$46.8 million for the quarter and 10.9% to $130.9 million for the nine months
ended April 30, 1998. Corresponding amounts for the fiscal year 1997 periods
were $42.0 million and $118.0 million, respectively.
 
     Effective August 1, 1997, the Company's Information Systems businesses have
been reported as a separate segment. Accordingly, the segment information for
the third quarter and nine months ended April 30, 1997 as discussed herein has
been restated to reflect this change.
 
     The Advanced Electronics segment reported sales and operating profit of
$407.8 million and $29.2 million for the third quarter of fiscal year 1998
compared with $419.8 million and $26.7 million, respectively, for the third
quarter of fiscal year 1997. Sales and operating profit for nine months of the
current fiscal year were $1.19 billion and $81.3 million compared with $1.14
billion and $70.6 million, respectively, for the nine months of fiscal year
1997. The improvements in sales and operating profit for the nine months of the
current year were primarily attributable to higher volume on programs in the
integrated avionics systems and radar warning systems businesses and the
acquisition of Racal Marine Group, a provider of marine electronic equipment, in
February 1997. Sales for the current year's third quarter decreased slightly
while operating margins improved as a result of reduced program costs in certain
defense electronics programs. Backlog for this segment at April 30, 1998 was
$1.48 billion compared with $1.61 billion at July 31, 1997.
 
     The Information Systems segment reported sales and operating profit of
$314.6 million and $16.3 million for the third quarter of fiscal year 1998
compared with $279.4 million and $18.9 million for the third quarter of fiscal
year 1997. For the nine months of the current fiscal year, sales and operating
profit were $829.4 million and $48.8 million compared with $792.3 million and
$53.5 million for the nine months of the prior fiscal year. The increase in
sales was mainly due to the acquisitions of TASC in April 1998 as described in
Note 4 of Notes to Consolidated Financial Statements and SAI Technology in March
1997. The contributions from these acquisitions were mitigated by lower volume
under the PRC Inc. subsidiary's ("PRC") Super-Minicomputer program, which is an
indefinite delivery/indefinite quantity contract with various U.S. Government
agencies to provide computer systems integration and networking solutions.
Operating profit was also impacted by investments in new programs and technology
made to address new market opportunities associated with software used in mobile
command and control systems and displays and computer products. Firm backlog at
April 30, 1998 for the Information Systems segment increased to $956.2 million
from $518.1 million at July 31, 1997 due mainly to the acquisition of TASC. In
addition, TASC and PRC have unfunded backlog with potential contract values of
$2.0 billion at April 30, 1998 compared with $1.5 billion for PRC at July 31,
1997.
 
     The Marine Engineering and Production segment reported sales and operating
profit of $279.5 million and $36.6 million for the third quarter of fiscal year
1998 compared with $286.2 million and $34.8 million for the third quarter of
fiscal year 1997. The respective amounts for the nine months of fiscal year 1998
were $740.9 million and $95.8 million compared with $835.9 million and $100.1
million for the nine months of fiscal year 1997. The decline in sales reflected
contracts completed during fiscal year 1997 and lower construction activities on
contracts nearing completion including an Aegis destroyer delivered during the
current quarter and a LHD class amphibious assault ship delivered shortly
thereafter. This sales decline was partially offset by other contracts moving
into more advanced stages of production, including a seventh LHD class
amphibious assault ship and three Aegis destroyers. Operating margins improved
as a result of increased earnings rates on programs maturing in the production
process and continued production efficiencies. Current construction activities
include four Aegis destroyers, one LHD class amphibious assault ship, and
multiple deepwater supply vessels for a commercial customer. During the current
quarter, the U.S. Navy awarded the
 
                                        9
<PAGE>   10
 
Company a contract to build six additional Aegis destroyers with options for two
more, which was the primary reason for the increase in backlog to $3.78 billion
at April 30, 1998 from $3.23 billion at July 31, 1997.
 
     The Electronic Components and Materials segment reported sales and
operating profit of $155.9 million and $26.7 million for the third quarter of
the current fiscal year compared with $128.4 million and $17.7 million for the
prior year's period. Sales and operating profit for the nine months of the
current fiscal year were $442.8 million and $72.4 million compared with $383.4
million and $51.4 million for the nine months of the prior fiscal year. These
improvements were driven by continued strong demand for this segment's
commercial electronics products used in the communications and computer
industries. Process improvements and cost reduction efforts also contributed to
the improved results.
 
     Net interest expense for the third quarter and nine months ended April 30,
1998 amounted to $14.4 million and $35.7 million compared with $11.3 million and
$33.2 million for the prior year's periods, respectively. To finance the
acquisition of TASC in April 1998, the Company issued $100 million principal
amount of 6.05% Senior Notes due 2003, $200 million principal amount of 6.75%
Senior Debentures due 2018 and sold commercial paper. In the second quarter of
the current fiscal year, the Company also incurred short-term borrowings in
connection with a payment of prior years' taxes. The payment included interest
which is deductible and, therefore, reduces estimated tax payments for fiscal
year 1998.
 
     Cash and marketable securities amounted to $60.0 million at April 30, 1998
compared with $19.9 million at July 31, 1997. Management believes that cash flow
from operations, along with availability under credit commitments, will be
sufficient to meet operating requirements.
 
     In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use." SOP 98-1 is
effective for the Company in its fiscal year 2000 and will require the
capitalization of certain costs incurred in connection with developing or
obtaining software for internal use. In April 1998, the AICPA issued SOP 98-5,
"Reporting on the Costs of Start-Up Activities." SOP 98-5 is also effective for
the Company in its fiscal year 2000 and will require that certain costs
associated with start-up activities and organization costs be expensed as
incurred. The Company does not expect the adoption of these statements to have a
material impact on its consolidated financial statements.
 
     The Company is continuing its efforts to evaluate the extent of year 2000
issues through internal programs initiated to identify and resolve such issues.
Costs incurred to date have not been significant and the remaining costs to be
incurred are not expected to have a material impact on the consolidated
financial statements. The Company believes it will satisfactorily resolve its
year 2000 issues.

ITEM 1. LEGAL PROCEEDINGS
 
     Litton is suing Honeywell, Inc. ("Honeywell") for patent infringement
relating to the manufacture of ring laser gyro navigation systems which are used
in commercial aircraft. After trial of that case in the U.S. District Court for
the Central District of California, on August 31, 1993, the jury rendered a
verdict in favor of Litton in the amount of $1.2 billion. On January 9, 1995,
the District Court released a Memorandum of Decision finding Litton's patent
invalid and rejecting the jury verdict. Litton appealed to the U.S. Court of
Appeals for the Federal Circuit. On July 3, 1996, the Court of Appeals rendered
a decision reversing the District Court's decision, finding the patent valid and
infringed by Honeywell. The Court of Appeals reinstated the jury's verdict on
liability including the findings of interference with contract and prospective
business advantage and ordered a new trial on the amount of damages sustained by
Litton in the District Court. On March 17, 1997, the U.S. Supreme Court vacated
the Court of Appeals ruling and remanded the case to the Court of Appeals for
further consideration in view of the Supreme Court's decision in Warner-Jenkins
Co. v. Hilton Davis Chemical Co. On September 30, 1997, a hearing took place
before the Court of Appeals. On April 7, 1998, the Court of Appeals reversed its
prior order remanding the case to the District Court for a new trial on damages
only. Instead, the Court of Appeals ordered a new trial on liability and damages
for the patent and interference with contract and prospective business advantage
claims. On April 21, 1998, Litton filed a motion asking the Court of Appeals to
reconsider its April 7 decision or for a hearing before the entire court.
Honeywell has filed opposition to the motion.
 
     Litton is also suing Honeywell on antitrust grounds in the same U.S.
District Court. On February 29, 1996, a jury rendered a verdict in favor of
Litton. On July 25, 1996, the District Court upheld the jury's verdict that
Honeywell attempted to illegally monopolize and did monopolize the market for
inertial reference systems for large commercial air transport, commuter and
business aircraft. However, the District Court declined to enter the $234
million jury verdict on the basis that Litton's damage study as presented failed
to disaggregate damages between illegal and legal acts. A new trial limited to
the issue of the amount of damages sustained by Litton attributable to
Honeywell's unlawful conduct has been ordered by the District Court. The
District Court set a trial date of October 13, 1998.

Counsel) with regard to the reduction in the Principal Amount of Securities
represented thereby, together with the written statement contemplated by the
last sentence of Section 2.4.

persons specified therein.

the Temporary Global Bearer Security shall be surrendered by the Common
Depositary to the Trustee or its agent, as the Company's agent for such purpose,
to be exchanged, in whole or from time to time in part, at the sole discretion
of the Company for (i) Bearer Securities or (ii) a permanent global Bearer
Security (the "Permanent Global Bearer Security") without charge to Holders, and
the principal Paying Agent or other Paying Agent outside the United States shall
authenticate and deliver (at an office or agency outside the United States), in
exchange for the Temporary Global Bearer Security or the portions thereof to be
exchanged, an equal aggregate principal amount of Bearer Securities or the
Permanent Global Bearer Security, as shall be specified by the beneficial owners
thereof; provided, however, that upon such presentation by the Common
Depositary, the Temporary Global Bearer Security is accompanied by a certificate
dated the Exchange Date or a subsequent date and signed by Euro- Clear as to the
portion of the Temporary Global Bearer Security held for its account then to be
exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by Cedel S.A. as to the portion of the Temporary Global Bearer Security

Global Bearer Security shall be substantially to the effect set forth in this
Indenture.

        Upon any such exchange of a portion of the Temporary Global Bearer
Security for Bearer Securities or the Permanent Global Bearer Security, the
Temporary Global Bearer Security shall be endorsed to reflect the reduction of
the principal amount evidenced thereby. Until so exchanged in full, the
Temporary Global Bearer Security shall in all respects be entitled to the same
benefits under, and subject to the same terms and conditions of, this Indenture
as Bearer Securities authenticated and delivered hereunder, except that none of
Euro-Clear, Cedel S.A. or the beneficial owners of the Temporary Global Bearer
Security shall be entitled to receive payment of interest or other payments

        than denominations of $5,000 and $100,000;

        in which payment of the Principal of and any interest on the Securities

        States, and if so, whether the Securities of the series may be satisfied
        and discharged other than as provided in Article VIII;

               (13) if the amount of payments of principal of and any interest
        on the Securities of the series is to be determined with reference to an
        index, formula or other method, or based on a coin or currency other
        than that in which the Securities are stated to be payable, the manner

        Securities and coupons, if any, of the series to any Holder who is a
        United States Alien (including any modification in the definition of
        such term), in respect of any tax, assessment or governmental charge
        withheld or deducted, under what circumstances and with what procedures
        and documentation the Company will pay such additional amounts, whether
        such additional amounts will be treated as interest or Principal
        pursuant to this Inden ture, and whether the Company will have the
        option to redeem such Securities rather than pay additional amounts (and
        the terms of any such option);

        "Business Day" when used with respect to any Securities of the series;

                (17) if and the terms and conditions upon which the Securities
        of the series may or must be converted into securities of the Company or
        exchanged for securities of the Company or another enterprise;

                                       12
<PAGE>   21

                (18) any terms applicable to Original Issue Discount, if any,
        (as that term is defined in the Internal Revenue Code of 1986 and the
        Regulations thereunder) including the rate or rates at which such
        Original Issue Discount, if any, shall accrue;

                (19) if the Securities of the series may be issued or delivered
        (whether upon original issuance or upon exchange of a temporary Security
        of such series or otherwise), or any installment of Principal of or any

        documents or satisfaction of other conditions in addition to those
        specified in this Indenture, the form and terms of such certificates,
        documents or conditions; and

               (20) any other terms of the series (which terms shall not be
        inconsistent with the provisions of this Indenture, except as permitted
        by Section 9.1(7)).

        All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except as to
denomination and the rate or rates of interest, if any, and Stated Maturity, the
date from which interest, if any, shall accrue and except as may otherwise be
provided in or pursuant to an Officers' Certificate pursuant to this Section
2.3(a) or in any indenture supplemental hereto. All Securities of any one series
need not be issued at the same time and, unless otherwise provided, a series may
be reopened for issuances of additional Securities of such series or for the
establishment of additional terms with respect to the Securities of such series.

        If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of any appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series. With respect to Securities of
a series subject to a Periodic Offering, such Board Resolution or Officers'
Certificate may provide general terms for Securities of such series and provide
either that the specific terms of particular Securities of such series shall be
specified in a Company Order or that such terms shall be determined by the
Company, or one or more of the Company's agents designated in an Officers'
Certificate, in accordance with the Company Order as contemplated by the first
proviso of the third paragraph of Section 2.4.

        (b) Unless otherwise provided as contemplated by Section 2.3(a) with
respect to any series of Securities, any Registered Securities of a series shall
be issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in denominations of $5,000 and
$100,000.

        SECTION II.4 Execution, Authentication, Delivery and Dating. The
Securities shall be executed on behalf of the Company by its Chairman of the
Board, one of its Vice Chairmen, its 

                                       13
<PAGE>   22

President or one of its Vice Presidents, or the Treasurer or any Assistant
Treasurer, attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.
Coupons shall bear the facsimile signature of the Treasurer or any Assistant
Treasurer of the Company.

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

        At any time and from time to time after the execution and delivery of
this Indenture (and subject to delivery of the Board Resolution or Officers'
Certificate or supplemental indenture as set forth in Section 2.3 with respect
to the initial issuance of Securities of any series), the Company may deliver
Securities of any series together with any coupons appertaining thereto,
executed by the Company to the Trustee or its authenticating agent with respect
to Bearer Securities for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee or its
authenticating agent with respect to Bearer Securities in accordance with such
Company Order shall authenticate and deliver such Securities; provided, however,
that, with respect to Securities of a series subject to a Periodic Offering, (a)
such Company Order may be delivered by the Company to the Trustee or its
authenticating agent with respect to Bearer Securities prior to the delivery to
the Trustee of such Securities for au thentication and delivery, (b) the Trustee
shall authenticate and deliver Securities of such series for original issue from
time to time, in an aggregate Principal Amount not exceeding the aggregate
Principal Amount established for such series, pursuant to a Company Order or
pursuant to such procedures acceptable to the Trustee as may be specified from
time to time by a Company Order, (c) the rate or rates of interest, if any, the
Stated Maturity or Maturities, the original issue date or dates, the redemption
provisions, if any, and any other terms of Securities of such series shall be
determined by a Company Order or pursuant to such procedures and (d) if provided
for in such procedures, such Company Order may authorize authentication and
delivery pursuant to oral or electronic instructions from the Company, or the
Company's duly authorized agent or agents designated in an Officers'
Certificate, which oral instructions shall be promptly confirmed in writing; and
provided, further, that, no Bearer Security or coupon shall be mailed or
otherwise delivered to any person who is not a United States Alien or to any
location in the United States. Except as permitted by Section 2.9, the
authenticating agent shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
cancelled.

        If the forms or terms of the Securities of the series and any related
coupons have been established in or pursuant to one or more Officers'
Certificates as permitted by Sections 2.1 and 2.3(a), in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 7.1) shall be fully protected in relying upon, an Opinion of
Counsel stating:

                                       14
<PAGE>   23

        (a) that the form and terms of such Securities and any coupons have been
duly authorized by the Company and established in conformity with the provisions
of this Indenture; and

        (b) that such Securities, together with any coupons appertaining
thereto, when authenti cated and delivered by the Trustee or its authenticating
agent and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company, enforceable in accordance with their terms, subject
to customary exceptions;

provided, however, that, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of
Securities of such series (provided that such Opinion of Counsel covers all
Securities of such series) and that the Opinion of Counsel above may state:

               (x) that the forms of such Securities have been, and the terms of
        such Securities (when established in accordance with such procedures as
        may be specified from time to time in a Company Order, all as
        contemplated by and in accordance with a Board Resolution or an
        Officers' Certificate or supplemental indenture pursuant to Section
        2.3(a), as the case may be) will have been, duly authorized by the
        Company and established in conformity with the provisions of this
        Indenture; and

                (y) that such Securities, together with the coupons, if any,
        appertaining thereto, when (1) executed by the Company, (2) completed,
        authenticated and delivered by the Trustee or in the case of Bearer
        Securities and coupons, an authenticating agent located outside the
        United States, in accordance with this Indenture, and (3) issued by the
        Company in the manner and subject to any conditions specified in such
        Opinion of Counsel, will constitute valid and legally binding
        obligations of the Company, enforce able in accordance with their terms,
        subject to customary exceptions.

        With respect to Securities of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company of any
of such Securities, the form and terms thereof and the legality, validity,
binding effect and enforceability thereof, upon the Opinion of Counsel and other
documents delivered pursuant to Sections 2.1 and 2.3(a) and this Section, as
applicable, at or prior to the time of the first authentication of Securities of
such series unless and until it has received written notification that such
opinion or other documents have been superseded or revoked. In connection with
the authentication and delivery of Securities of a series subject to a Periodic
Offering, the Trustee shall be entitled to assume, unless it has actual
knowledge to the contrary, that the Company's instructions to authenticate and
deliver such Securities do not violate any rules, regulations or orders of any
governmental agency or commission having jurisdiction over the Company.


                                       15
<PAGE>   24

        Notwithstanding the provisions of Section 2.3(a) and of the preceding
three paragraphs, if all Securities of a series are subject to a Periodic
Offering, it shall not be necessary to deliver the Officers' Certificate
otherwise required pursuant to Section 2.3(a) at or prior to the time of
authentication of each Security of such series if such Officers' Certificate is
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

        Each Registered Security shall be dated the date of its authentication;
and, unless otherwise specified as contemplated by Section 2.3(a), each Bearer
Security (including a Bearer Security represented by a temporary global
Security) shall be dated as of the date of original issuance of the first
Security of such series to be issued.

        The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities. Unless otherwise provided in the
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent.

        No Security or coupon 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 duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder. The Trustee's certificate of authentication shall be in
substantially the following form:

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

                                    The Bank of New York, as Trustee



                                    By:
                                       ---------------------------------------
                                                Authorized Signatory


        Notwithstanding the foregoing, if any Security shall have been duly
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 2.12 together with a written statement (which need not
comply with Section 12.4 or 12.5 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall 


                                       16
<PAGE>   25

be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.

        SECTION II.5 Registrar and Paying Agent. The Company shall maintain,
with respect to each series of Securities, an office or agency where such
Securities may be presented for registration of transfer or for exchange
("Registrar") and an office or agency where such Securities may be presented for
purchase or payment ("Paying Agent"). The Registrar shall keep a register of the
Securities and of their transfer and exchange. The Company may have one or more
co-registrars and one or more additional paying agents. The term Paying Agent
includes any additional paying agent.

        The Company shall enter into an appropriate agency agreement with
respect to each series of Securities with any Registrar, Paying Agent or
co-registrar (if not the Trustee). The agreement shall implement the provisions
of this Indenture that relate to such agent. The Company shall notify the
Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent for a particular series of Securities, the
Trustee shall act as such and shall be entitled to appropriate compensa tion
therefor pursuant to Section 7.7. The Company or any Subsidiary or an Affiliate
of either of them may act as Paying Agent, Registrar or co-registrar.

        The Company initially appoints the Trustee as the Registrar and Paying
Agent in connection with such Securities and the Trustee, acting through its
main office in London or as provided in the Officer's Certificate establishing
the Securities, as paying agent and authenticating agent for Bearer Securities.

        SECTION II.6 Paying Agent to Hold Money and Securities in Trust. Except
as otherwise provided herein, prior to or on each due date of payments in
respect of any series of Securities, the Company shall deposit with the Paying
Agent with respect to such Securities a sum of money sufficient to make such
payments when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Holders or the Trustee all money held by such Paying
Agent for the making of payments in respect of the Securities of such series and
shall notify the Trustee of any default by the Company in making any such
payment. At any time during the continuance of any such default, a Paying Agent
shall, upon the written request of the Trustee, forthwith pay to the Trustee all
money so held in trust with respect to such Securities. If the Company, a
Subsidiary or an Affiliate of either of them acts as Paying Agent for a series
of Securities, it shall segregate the money held by it as Paying Agent with
respect to such Securities and hold it as a separate trust fund. The Company at
any time may require a Paying Agent for a series of Securities to pay all money
held by it with respect to such Securities to the Trustee and to account for any
money disbursed by it. Upon doing so, such Paying Agent shall have no further
liability for the money.

                                       17

<PAGE>   26

        SECTION II.7 Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders of each series of Securities. If the
Trustee is not the Registrar for any series of Securities, the Company shall
cause to be furnished to the Trustee at least semiannually on June 1 and
December 1 a listing of Holders of such series of Securities dated within 15
days of the date on which the list is furnished and at such other times as the
Trustee may request in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders of
such series of Securities.

        SECTION II.8 Transfer and Exchange. Upon surrender for registration of
transfer of any Security at the office or agency of the Company designated
pursuant to Section 4.5 for such purpose in a Place of Payment, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of any
authorized denomination or denominations of a like aggregate Principal Amount
and tenor. The Company shall not charge a service charge for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
pay all taxes, assessments or other governmental charges that may be imposed in
connection with the transfer or exchange of the Securities from the
Securityholder requesting such transfer or exchange (other than any exchange of
a temporary Security for a definitive Security not involving any change in
ownership or any exchange pursuant to Section 2.11, 3.6, 9.5 or 10.3, not
involving any transfer).

        Notwithstanding any other provisions (other than the provisions set
forth in the sixth and seventh paragraphs) of this Section, a Security in global
form representing all or a portion of the Securities of a series may not be
transferred except as a whole by the Depositary for such series to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor Depositary for such series or a nominee of such successor Depositary.

        At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
denomination or denominations, of a like aggregate Principal Amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive. Bearer Securities may not
be issued in exchange for Registered Securities.

        At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denomination or denominations and of a like aggregate Principal Amount and
tenor, upon surrender of the Bearer 


                                       18
<PAGE>   27

        Securities to be exchanged at any office or agency of the Company
located outside the United States, with all unmatured coupons and all matured
coupons in default thereto appertaining. If the Holder of a Bearer Security is
unable to produce any such unmatured coupon or coupons or matured coupon or
coupons in default, such exchange may be effected if the Bearer Securities are
accompanied by payment in funds acceptable to the Company and the Trustee or
Paying Agent in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company, the Paying Agent and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless. If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing coupon in respect of which such a payment shall
have been made, such Holder shall be entitled to receive the amount of such
payment; provided, however, that, except as otherwise provided in Section 4.5,
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in exchange for a Regis tered
Security of the same series and like tenor after the close of business at such
office or agency on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or
agency on the related proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Inden ture.

        Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee or a duly appointed authenticating agent shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

        If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series, the Company shall appoint a successor Depositary with
respect to the Securities of such series. If a successor Depositary for the
Securities of such series is not appointed by the Company within 90 days after
the Company receives such notice, the Company will execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Securities of such series, will authenticate and deliver Securities
of such series in definitive form in an aggregate Principal Amount equal to the
Principal Amount of the Security or Securities in global form representing such
series in exchange 


                                       19
<PAGE>   28

for such Security or Securities in global form in accordance with the
instructions, if any, of the Depositary.

        The Company may at any time and in its sole discretion determine that
the Securities of any series issued 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 Order
for the authentication and delivery of definitive Securities of such series,
will authenticate and deliver Securities of such series in definitive form and
in an aggregate Principal Amount equal to the Principal Amount of the Security
or Securities in global form representing such series in exchange for such
Security or Securities in global form in accordance with the instructions, if
any, of the Depositary.

        Notwithstanding the foregoing, except as otherwise specified in the
preceding two paragraphs or as contemplated by Section 2.3(a), any global
Security shall be exchange able only as provided in this paragraph. If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities of such series and of like Principal
Amount and tenor but of another authorized form and denomination, as specified
as contemplated by Section 2.3(a), then without unnecessary delay but in any
event not later than the earliest date on which such interests may be so
exchanged, the Company shall deliver to the Trustee definitive Securities in
aggregate Principal Amount equal to the Principal Amount of such global
Security, executed by the Company. On or after the earliest date on which such
interests may be so exchanged, such global Security shall be surrendered by the
Depositary with respect thereto to the Trustee, as the Com pany's agent for such
purpose, to be exchanged, in whole or from time to time in part, for definitive
Securities without charge and the Trustee or, in the case of Bearer Securities,
an authenticating agent outside the United States shall authenticate and
deliver, in exchange for each portion of such global Security, an equal
aggregate Principal Amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged which, unless the Securities of the series are not
issuable both as Bearer Securities and as Registered Securities, as specified as
contem plated by Section 2.3(a), shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof; pro vided, however, that notwithstanding the last
paragraph of this Section 2.8, no such ex changes may occur during a period
beginning at the opening of business 15 days before any selection of Securities
of that series to be redeemed and ending on the relevant Redemption Date; and
provided, further, that no Bearer Security or coupon delivered in exchange for a
portion of a global Security shall be mailed or otherwise delivered to any
person that is not a United States Alien or to any location in the United
States. If a Registered Security is issued in exchange for any portion of a
global Security after the close of business at the office or agency where such
exchange occurs on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant 


                                       20


<PAGE>   29

Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related proposed date for payment of
Defaulted Interest, interest or Defaulted Interest, as the case may be, will not
be payable on such Interest Payment Date or proposed date for payment, as the
case may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such global Security
is payable in accordance with the provisions of this Indenture.

        Upon the exchange of a Security in global form for Securities in
definitive form, such Security in global form shall be cancelled by the Trustee.
All cancelled Securities and coupons held by the Trustee shall be destroyed by
the Trustee and a certificate of their destruction delivered to the Company
unless the Company directs, by Company Order, that the Trustee shall cancel
Securities and return them to the Company. Registered Secu rities issued in
exchange for a Security in global form pursuant to this Section 2.8 shall be
registered in such names and in such authorized denominations as the Depositary
for such Security in global form, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Registered Securities to the persons in whose names such
Securities are so registered.

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

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

        The Company shall not be required (i) to issue, register the transfer of
or ex change Securities of any series during a period beginning at the opening
of business 15 days before any selection of Securities of that series to be
redeemed and ending (except as otherwise provided in the first proviso in the
eighth paragraph of this Section 2.8) at the close of business on (A) if
Securities of the Series are issuable only as Registered Securi ties, the day of
the mailing of the relevant notice of redemption and (B) if Securities of the
series are issuable as Bearer Securities, the day of the first publication of
the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption, in whole or in
part, except the unredeemed portion of any Security being redeemed in part, or
(iii) to exchange any Bearer Security so selected for redemption except that
such a 

                                       21
<PAGE>   30

Bearer Security may be exchanged for a Registered Security of that series
and like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemp tion.

        SECTION II.9 Replacement Securities and Coupons. If (a) any mutilated
Security or a Security with a mutilated coupon appertaining thereto is
surrendered to the Trustee or paying agent outside the United States, or (b) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security or coupon, and 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 written notice to
the Company, any such paying agent or the Trustee that such Security or coupon
has been acquired by a bona fide purchaser, the Company shall execute and upon
its written request the Trustee or paying agent outside the United States shall
authenticate and deliver, in exchange for any such mutilated Security or coupon
or in lieu of any such destroyed, lost or stolen Security or coupon, or in
exchange for the Security to which a mutilated, destroyed, lost or stolen coupon
appertains (with all appurtenant coupons not mutilated, destroyed, lost or
stolen), a new Security of the same series and of like tenor and Principal
Amount, bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to such destroyed, lost or
stolen Security or coupon, or to the Security to which such destroyed, lost or
stolen coupon appertains.

        In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security or coupon; provided,
however, that the Principal of and any interest on Bearer Securities shall,
except as otherwise provided in Section 4.5, be payable only at an office or
agency located outside the United States and, unless otherwise specified as
contemplated by Section 2.3(a), any interest on Bearer Securities shall be
payable only upon presentation and surrender of the coupons apper taining
thereto.

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

        Every new Security of any series issued pursuant to this Section in lieu
of any mutilated, destroyed, lost or stolen Security, or in exchange for a
Security to which a mutilated, destroyed, lost or stolen coupon appertains,
shall constitute an original addi tional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and any such new Security and coupons, if any, shall be 

                                       22
<PAGE>   31

entitled to all benefits of this Indenture equally and proportionately with any
and all other Securities of that issue and their coupons, if any, 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 or coupons.

        SECTION II.10 Outstanding Securities; Determinations of Holders' Action
 . Securities of any series "Outstanding" at any time are, as of the date of
determination, all the Securities of such series theretofore authenticated by
the Trustee for such series except for those cancelled by it, those delivered to
it for cancellation and those described in this Section 2.10 as not outstanding.
A Security does not cease to be "Outstanding" because the Company or an
Affiliate thereof holds the Security; provided, however, that in determining
whether the Holders of the requisite Principal Amount of Outstanding Securities
have given or concurred in any request, demand, authorization, direction,
notice, consent or waiver hereunder, Securities owned by the Company or any
other obligor upon the Securities or any Affiliate of the Company or such other
obligor shall be disregarded and deemed not to be outstanding, except that, in
determining whether the Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent or waiver, only
Securities which a Trust Officer knows to be so owned shall be so disre garded.
Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Company or any other obligor upon the Securities or any Affiliate of
the Company or of such other obligor. Subject to the foregoing, only Securities
outstanding at the time of such determination shall be considered in any such
determination (including, without limitation, determinations pursuant to
Articles 6 and 9). In addition, in determining whether the Holders of the
requisite Principal Amount of Outstanding Securities have given or concurred in
any request, demand, authorization, direction, notice, consent or waiver
hereunder, (i) the Principal Amount of a Discount Security that shall be deemed
to be Outstanding shall be the amount of the Principal thereof that would be due
and payable as of the date of such determination upon acceleration of the
Maturity thereof pursuant to Section 6.2, (ii) the Principal Amount of a
Security denominated in a foreign currency or currencies shall be the Dollar
equivalent, as determined on the date of original issuance of such Security, of
the Principal Amount (or, in the case of a Discount Security, the Dollar
equivalent on the date of original issuance of such Security of the amount
determined as provided in (i) above) of such Security.

        If a Security has been paid pursuant to Section 2.9 or in exchange for
or in lieu of which another Security has been authenticated and delivered
pursuant to this Indenture, it ceases to be outstanding unless the Trustee
receives proof satisfactory to it that the replaced Security is held by a bona
fide purchaser.


                                       23

<PAGE>   32

        If the Trustee (other than the Company) holds, in accordance with this
Indenture, on a Redemption Date or on Stated Maturity, money sufficient to pay
Securities and any coupons thereto appertaining payable on that date, then on
and after that date such Securities shall cease to be outstanding and interest,
if any, on such Securities shall cease to accrue; provided, that if such
Securities are to be redeemed, notice of such redemption has been duly given
pursuant to this Indenture or provision therefor satisfactory to the Trustee has
been made.

        SECTION II.11 Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute, and upon Company
Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
Officers executing such Securities may determine, as conclusively evidenced by
their execution of such Securities. Such temporary Securities may be in global
form.

        Except in the case of Securities represented by a temporary global
Security (which shall be exchanged in accordance with the provisions of the
three succeeding paragraphs), if temporary Securities for some or all of the
Securities of any series are issued, the Company will cause definitive
Securities representing such Securities to be prepared without unreasonable
delay. Subject to Section 2.2, after the preparation of such definitive
Securities, the temporary Securities shall be exchangeable for such definitive
Securities of like tenor upon surrender of the temporary Securities at the
office or agency of the Company designated for such purpose pursuant to Section
4.5 in a Place of Payment for such series for the purpose of exchanges of
Securities of such series, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities of any series (accompanied
by any unmatured coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like Principal
Amount of definitive Securities of the same series and of like tenor of
authorized denomi nations; provided, however, that no definitive Bearer Security
or Permanent Global Bearer Security shall be delivered in exchange for a
temporary Registered Security. Until so ex changed the temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

        Unless otherwise specified as contemplated by Section 2.3(a), if Bearer
Securities of any series are represented by a Security in temporary global form,
any such temporary global Security shall be delivered to the Depositary for the
benefit of Euro-clear and Cedel S.A., for credit to the respective accounts of
the beneficial owners of such Securities (or to such other accounts as they may
direct).


                                       24

<PAGE>   33

        Without unnecessary delay but in any event not later than the Exchange
Date, the Company shall deliver to the Trustee or paying agent outside the
United States permanent Securities of the same series which may be in definitive
or global form at the sole discretion of the Company, in aggregate Principal
Amount equal to the Principal Amount of such temporary global Security, executed
by the Company. On or after the Exchange Date, such temporary global Security
shall be surrendered by the Depositary to the Trustee or paying agent outside
the United States, as the Company's agent for such purpose, to be exchanged, in
whole or from time to time in part, for permanent Securities of the same series
which may be in definitive or global form at the sole discretion of the Company
and of like tenor without charge and the Trustee shall authenticate and deliver,
in exchange for each portion of such temporary global Security, an equal
aggregate Principal Amount of definitive Securities or interests in the
Permanent Global Bearer Security of the same series of authorized denominations
and of like tenor as the portion of such temporary global Security to be
exchanged. The permanent Securities to be delivered in exchange for any such
temporary global Security shall be in definitive bearer form or registered form,
or shall be represented by a Permanent Global Bearer Security, or any
combination thereof, as specified as contemplated by Section 2.3(a), and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof provided, that no beneficial owner of a registered Temporary Global
Bearer Security who is not a United States alien or who is located in the United
States shall be entitled to receive Bearer Securities.

        Unless otherwise specified in any such Temporary Global Bearer Security,
the interest of a beneficial owner of Securities of a series represented by such
Temporary Global Bearer Security shall be exchanged for permanent Securities of
the same series which may be in definitive or global form at the sole discretion
of the Company and of like tenor following the Exchange Date when the account
holder instructs Euro-clear or Cedel S.A., as the case may be, to request such
exchange on his behalf and delivers to Euro-clear or Cedel S.A., as the case may
be, any certificate specified as contemplated by Section 2.3(a). Unless
otherwise specified in such Temporary Global Bearer Security, any such exchange
shall be made free of charge to the beneficial owners of such Temporary Global
Bearer Security, except that a person receiving permanent Securities must bear
the cost of insurance, postage, transportation and the like in the event that
such person does not take delivery of such permanent Securities in person at the
offices of Euro-clear or Cedel S.A.

        Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as permanent Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 2.3(a), interest payable on a temporary
global Security representing a series of Bearer Securities on an Interest
Payment Date for Securities of such series occurring prior to the applicable
Exchange Date 


                                       25
<PAGE>   34

shall be payable to Euro-clear and Cedel S.A. on such Interest Payment Date,
upon delivery by Euro-clear and Cedel S.A. to a paying agent outside the United
States of any certificate specified as contemplated by Section 2.3(a), for
credit without further interest on or after such Interest Payment Date to the
respective accounts of the persons who are the beneficial owners of such
Temporary Global Bearer Security on such Interest Payment Date and who have each
delivered to Euro-clear or Cedel S.A., as the case may be, any certificate
specified as contemplated by Section 2.3(a).

        SECTION II.12 Cancellation. All Securities or coupons surrendered for
payment, redemption, registration of transfer or exchange, or for credit against
any sinking fund payment, shall, if surrendered to any person other than the
Trustee, be delivered to the Trustee and all Registered Securities and matured
coupons so delivered shall be promptly cancelled by it. All Bearer Securities
and unmatured coupons so delivered shall be held by the Trustee and shall be
cancelled. 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 (including Securities
received by the Company in exchange or payment for other Securities of the
Company) and may deliver to the Trustee (or to any other person for delivery to
the Trustee) for cancellation any Securities previously authenticated hereunder
which the Company has not issued and sold, and all Securities so delivered shall
be promptly cancelled by the Trustee. The Company may not reissue, or issue new
Securities to replace, Securities it has paid or delivered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted in the form of Securities for any particular series or as permitted by
this Indenture. All cancelled Securities and coupons held by the Trustee shall
be returned to the Company.

        SECTION II.13 Payment of Interest; Interest Rights Preserved. Unless
otherwise provided as contemplated by Section 2.3(a) with respect to any series
of Securities, interest on any Registered 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. In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture.


                                       26
  

<PAGE>   35

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

                (1) The Company may elect to make payment of any Defaulted
        Interest to the persons in whose names the Securities of such series (or
        their respective Prede cessor 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 Registered Security and the date of the
        proposed payment, and at the same time the Company shall deposit with
        the Trustee an amount of money equal to the aggregate amount proposed to
        be paid in respect of such Defaulted Interest or shall make arrangements
        satisfactory to the Trustee for such deposit prior to the date of the
        proposed payment, such money when deposited to be held in trust for the
        benefit of the persons entitled to such Defaulted Interest as in this
        Clause provided. Thereupon the Trustee shall fix a Special Record Date
        for the payment of such Defaulted Interest which shall be not more than
        15 days and not less than 10 days prior to the date of the proposed
        payment and not less than 10 days after the receipt by the Trustee of
        the notice of the proposed payment. The Trustee shall promptly notify
        the Company of such Special Record Date and, in the name and at the
        expense of the Company, shall cause notice of the proposed payment of
        such Defaulted Interest and the Special Record Date therefor to be
        mailed, first-class postage prepaid, to each Holder of Registered
        Securities at his address as it appears in the register of the
        Securities, not less than 10 days prior to such Special Record Date.
        Notice of the proposed payment of such Defaulted Interest and the
        Special Record Date therefor having been so mailed, such Defaulted
        Interest shall be paid to the persons in whose names the Securities (or
        their respective Predecessor Securities) are registered at the close of
        business on such Special Record Date and shall no longer be payable
        pursuant to the following Clause (2).

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

        Subject to the foregoing provisions of this Section and Section 2.8,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu 

                                       27
<PAGE>   36

of any other Security shall carry the rights to interest accrued and unpaid, and
to accrue, which were carried by such other Security.

        SECTION II.14 Persons Deemed Owners. Prior to due presentment of a
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the person in whose name such
Registered Security is registered as the owner of such Registered Security for
the purpose of receiving payment of Principal of and (except as otherwise
specified as contem plated by Section 2.3(a) and subject to Section 2.8 and
Section 2.13) interest on such Registered Security and for all other purposes
whatsoever, whether or not such Registered 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.

        Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
as the absolute owner of such Bearer Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Bearer Security or coupon 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.

        None of the Company, the Trustee, any Paying Agent or the 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 Security in
global form or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

        SECTION II.15 Computation of Interest. Except as otherwise specified as
contemplated by Section 2.3(a) for Securities of any series, (i) interest on any
Securities which bear interest at a fixed rate shall be computed on the basis of
a 360-day year comprised of twelve 30-day months and (ii) interest on any
Securities which bear interest at a variable rate shall be computed on the basis
of the actual number of days in an interest period divided by 360.

                                   ARTICLE III

                                   REDEMPTION

        SECTION III.1 Right to Redeem; Notices to Trustee. Securities of any
series which are redeemable before their Stated Maturity shall be redeemable in
accordance with their terms and (except as otherwise specified as contemplated
by Section 2.3(a) for Securities of any series) in accordance with this Article.
In the case of any redemption at 

                                       28
<PAGE>   37

the election of the Company of less than all the Securities of any series, the
Company shall, within the time period set forth below, notify the Trustee in
writing of the Redemption Date, the Principal Amount of and of any other
information necessary to identify the Securities of such series to be redeemed
and the Redemption Price (including the information set forth in clauses (4),
(5) and (6) of Section 3.3).

        The Company shall give the notice to the Trustee provided for in this
Section 3.1 at least 60 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee).

        SECTION III.2 Selection of Securities to be Redeemed. Unless otherwise
specified as contemplated by Section 2.3(a) with respect to any series of
Securities, if less than all the Securities of any series with the same issue
date, interest rate and Stated Maturity are to be redeemed, the Trustee shall
select the particular Securities to be redeemed by such method the Trustee
considers fair and appropriate, which method may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the Principal
Amount of Registered Securities of such series of a denomination larger than the
minimum authorized denomination for Securities of that series. The Trustee shall
make the selection not more than 60 days before the Redemption Date from
Outstanding Securities of such series not previously called for redemption.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly in writing of the Securities to be redeemed and, in the
case of any portions of Securities to be redeemed, the principal amount thereof
to be redeemed.

        SECTION III.3 Notice of Redemption. Unless otherwise specified as
contemplated by Section 2.3(a) with respect to any series of Securi ties, at
least 30 days but not more than 60 days before a Redemption Date, the Company
shall mail a notice of redemption by first-class mail, postage prepaid, to each
Holder of Securities to be redeemed.

        The notice shall identify the Securities (including CUSIP/ISIN numbers)
to be re deemed and shall state:

               (1   the Redemption Date;
               (2   the Redemption Price;

               (3 if fewer than all the Outstanding Securities of any series are
        to be re deemed, the identification (and, in the case of partial
        redemption, the Principal Amounts) of the particular Securities to be
        redeemed;

                                       29
<PAGE>   38


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

               (5 the place or places where such Securities, together in the
        case of Bearer Securities with all coupons appertaining thereto, if any,
        maturing after the Redemption Date, are to be surrendered for payment of
        the Redemption Price; and

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

A notice of redemption published as contemplated by Section 12.2 need not
identify particular Registered Securities to be redeemed.

        At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense; provided,
however, that, in all cases, the text of such Company notice shall be prepared
by the Company.

        SECTION III.4 Effect of Notice of Redemption. Once notice of redemption
is given, Securities called for redemption become due and payable on the
Redemption Date and at the Redemption Price stated in the notice, and from and
after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest) such Securities shall cease to bear
interest and the coupons for such interest appertaining to any Bearer Securities
so to be redeemed, except to the extent provided below, shall be void. Upon
surrender of any such Security for redemption in accordance with said notice,
together with all coupons, if any, appertaining thereto maturing after the
Redemption Date, such Security shall be paid by the Company at the Redemption
Price, together with accrued interest to the Redemption Date; provided, however,
that installments of interest on Bearer Securities whose Stated Maturity is on
or prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 4.5)
and, unless otherwise specified as contemplated by Section 2.3(a), only upon
presentation and surrender of coupons for such interest; and provided, further,
that, unless otherwise specified as contemplated by Section 2.3(a), installments
of interest on Registered Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Dates according to their terms and the provisions of
Sections 2.8 and 2.13.

        If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such miss ing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and a paying agent
located outside the United States if there be furnished to the



                                       30

<PAGE>   39
Company, the Trustee and such paying agent such security or indemnity as they
may require to save each of them and any Paying Agent harmless. If thereafter
the Holder of such Security shall surrender to any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only at
an office or agency located outside the United States (except as otherwise
provided in Section 4.5) and, unless otherwise specified as contem plated by
Section 2.3(a), only upon presentation and surrender of those coupons.

        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 prescribed therefor in the Security.

        SECTION III.5 Deposit of Redemption Price. Prior to 10:00 am, New York
Time on the Redemption Date, the Company shall deposit in the Place of Payment
with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of
either of them is the Paying Agent, shall segregate and hold in trust) money
sufficient to pay the Redemption Price and (except if the Redemption Date shall
be an Interest Payment Date) accrued interest on, of all Securities to be
redeemed on that date other than Securities or portions of Securities called for
redemption which prior thereto have been delivered by the Company to the Trustee
for cancellation. If such money is then held by the Company in trust and is not
required for such purpose, it shall be discharged from such trust.

        SECTION III.6 Securities Redeemed in Part. Any Registered Security which
is to be redeemed only in part shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by,
or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing), and upon such surrender, the Company shall execute and the Trustee
shall authenticate and deliver to the Holder of such Security a new Registered
Security or Securities of the same series and of like tenor, in an authorized
denomination as requested by such Holder, equal in aggregate Principal Amount to
and in exchange for the unredeemed portion of the Principal of the Security
surrendered.

                                    ARTICLE IV

                                     COVENANTS

        SECTION IV.1 Payment of Securities. The Company shall promptly make all
payments in respect of each series of Securities on the dates and in the manner
provided in the Securities and any coupons appertaining thereto and, to the
extent not otherwise so provided, pursuant to this Indenture. An installment of
Principal of or interest on the 

                                       31

Securities shall be considered paid on the date it is due if the Trustee or a
Paying Agent (other than the Company or an Affiliate of the Company) holds on
that date funds (in the currency or currencies of payment with respect to such
Securi ties) designated for and sufficient to pay such installment. Unless
otherwise specified as contemplated by Section 2.3(a) with respect to any series
of Securities, any interest due on Bearer Securities on or before Maturity shall
be payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature. At the
Company's option, payments of Principal or interest may be made by check or by
transfer to an account maintained by the payee subject, in the case of Bearer
Securities, to the provisions of Section 4.5.

        SECTION IV.2 SEC Reports. The Company shall file with the Trustee,
within 15 days after it files such annual and quarterly reports, information,
documents and other reports with the SEC, copies of its annual report and of the
information, documents and other reports (or copies of such portions of any of
the foregoing as the SEC may by rules and regulations prescribe) which the
Company is re quired to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act. The Company also shall comply with the other provisions of TIA
Section 314(a).

        SECTION IV.3 Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year (beginning with the
fiscal year ending on July 31, 1997) an Officers' Certificate stating whether or
not the signers know of any Default that occurred during such period. If they
do, such Officers' Certificate shall describe the Default and its status.

        SECTION IV.4 Further Instruments and Acts. Upon request of the Trustee,
the Company will execute and deliver such further instruments and do such
further acts as may be reasonably necessary or proper to carry out more
effectively the purposes of this Indenture.

        SECTION IV.5 Maintenance of Office or Agency. If Securities of a series
are issuable only as Registered Securities, the Company will maintain in each
Place of Payment for such series an office or agency where Securi ties of that
series may be presented or surrendered for payment, where Securities of that
series may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served. If Securities of a series are issuable
as Bearer Securities, the Company will maintain (A) in the Borough of Manhattan,
the City of New York, an office or agency where any Registered Securities of
that series may be presented or surrendered for payment, where any Registered
Securities of that series may be surrendered for registration of transfer, where
Securities of that series may be surrendered for exchange, purchase or
redemption and where notices and demands to or upon the Company in respect of
the Securities of that 

                                       32

series and this Indenture may be served and where Bearer Securities of that
series and related coupons may be presented or surrendered for payment in the
circumstances described in the following paragraph (and not otherwise), (B)
subject to any laws or regulations applicable thereto, in a Place of Payment for
that series which is located outside the United States, an office or agency
where Securities of that series and related coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Securities of that series pursuant to Section 4.6), and (C) subject to any laws
or regulations applicable thereto, in a Place of Payment for that series located
outside the United States an office or agency where any Registered Securities of
that series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The office of the Trustee in New York, New York, shall be such
office or agency for all of the afore said purposes unless the Company shall
maintain some other office or agency for such purposes and shall give prompt
written notice to the Trustee of the location, and any change in the location,
of such other office or agency. If at any time the Company shall fail to
maintain any such required office or agency in respect of any series of
Securities or shall fail to furnish the Trustee with the address thereof, such
presentations and surrenders of Securities of that series may be made and
notices and demands may be made or served at the address of the Trustee set
forth in Section 12.2, except that Bearer Securities of that series and the
related coupons may be presented and surrendered for payment (including payment
of any additional amounts payable on Bearer Securities of that series pursuant
to Section 4.6) at the place specified for that purpose as contemplated by
Section 2.3(a) or, if no such place is specified, at the main office of The Bank
of New York, London branch, and the Company hereby appoints the same as its
agent to receive such respective presentations, surrenders, notices and demands.

        No payment of Principal or interest on Bearer Securities shall be made
at any office or agency of the Company in the United States, by check mailed to
any address in the United States, by transfer to an account located in the
United States or upon presentation or surrender in the United States of a Bearer
Security or coupon for payment, even if the payment would be credited to an
account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
Principal of and any interest on any such Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section 4.6)
shall be made at the office of the Company's Paying Agent in the Borough of
Manhattan, The City of New York, if (but only if) payment in Dollars of the full
amount of such Principal, interest or additional amounts, as the case may be, at
all offices or agencies outside the United States maintained for such purpose by
the Company in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions.

                                       33
<PAGE>   42

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

        SECTION IV.6 Additional Amounts. If specified as contemplated by Section
2.3(a), the Securities of a series may provide for the payment of additional
amounts, and in such case, the Company will pay to the Holder of any Security of
such series or any coupon appertaining thereto additional amounts as provided
therein. Wherever in this Indenture there is mentioned, in any context, the
payment of the Principal of or any interest on, or in respect of, any Security
of any series or payment of any related coupon, such mention shall be deemed to
include mention of the payment of additional amounts provided for in this
Section to the extent that, in such context, addi tional amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section
and express mention of the payment of additional amounts (if applicable) in any
provisions hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made.

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

        SECTION V.1 When Company May Merge or Transfer Assets.V.1 When Company

series of related transactions, shall not consolidate with or merge with or into
any other person or convey or transfer (by lease, assignment, sale or otherwise)
all or substantially all 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 conveyed or transferred
        (i) shall be a corporation, partnership, limited liability company or

        States or any state thereof or the District of Columbia and (ii) shall
        expressly assume, by an indenture supplemental hereto, executed and

        the obligations of the Company under the Securities and this Indenture;

               (b) immediately after giving effect to such transaction and the
        assumption contemplated by clause (a)(ii) above, no Default or Event of

        Certificate and an Opinion of Counsel, each stating that such consolida
        tion, merger, conveyance or transfer and, if a supplemental indenture is
        required in connection with such transaction, such supplemental
        indenture, comply with this Article and that all conditions precedent
        herein provided for relating to such transaction have been satisfied.

to be the conveyance or transfer of all or substantially all of the properties
and assets of the Company.

succeed to, and be substituted for, and may exercise every right and power of
the Com pany 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 from all obligations and covenants under this Indenture, the
Securities and coupons. 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 VI

                              DEFAULTS AND REMEDIES

        SECTION VI.1 Events of Default. Unless otherwise specified as 
contemplated by Section 2.3(a) with respect to any series of securities, an
"Event of Default" occurs, with respect to each series of the Securities
individually, if:

               (1 the Company defaults in (a) the payment of the principal of
        any Security of such series at its Maturity or (b) the payment of any
        interest upon any Security of such series when the same becomes due and
        payable and continuance of such default for a period of 30 days;

               (2 the Company fails to comply with any of its agreements in the
        Securi ties or this Indenture (other than those referred to in clause
        (1) above and other than a covenant or warranty a default in whose
        performance or whose breach is elsewhere in this Section specifically
        dealt with or which has been expressly included in this Indenture solely
        for the benefit of a series of Securities other than such series) and
        such failure continues for 60 days after receipt by the Company of a
        Notice of Default;

               (3 there shall have been the entry by a court of competent
        jurisdiction of (a) a decree or order for relief in respect of the
        Company in an involuntary case or proceeding under any applicable
        Bankruptcy Law or (b) a decree or order adjudg ing the Company bankrupt
        or insolvent, or seeking reorganization, arrangement, adjustment or
        composition of or in respect of the Company under any applicable federal
        or state law, or appointing a custodian, receiver, liquidator, assignee,
        trustee, sequestrator (or other similar official) of the Company or of
        any substan tial part of its property, or ordering the wind up or
        liquidation of its affairs, and any such decree or order for relief
        shall continue to be in effect, or any such other decree or order shall
        be unstayed and in effect, for a period of 60 consecutive days;

               (4 (a) the Company commences a voluntary case or proceeding under
        any applicable Bankruptcy Law or any other case or proceeding to be
        adjudicated bankrupt or insolvent, (b) the Company consents to the entry
        of a decree or order for relief in respect of the Company in an
        involuntary case or proceeding under any applicable Bankruptcy Law or to
        the commencement of any bankruptcy or insolvency case or proceeding
        against it, (c) the Company files a petition or answer or consent
        seeking reorganization or substantially comparable relief under any
        applicable federal state law, (d) the Company (x) consents to the filing
        of such petition or the appointment of, or taking possession by, a
        custodian, receiver, liquidator, assignee, trustee, sequestrator or
        similar official of the Company or of any substantial part of its
        property, (y) makes an assignment for the benefit of creditors or (z)
        admits in writing its inability to pay its debts generally as they
        become due or (e) the Company takes any corporate action in furtherance
        of any such actions in this clause (4); or

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

               "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors. "Custodian" means any
receiver, trustee, assignee, liquidator, custodian or similar official under any
Bankruptcy Law.

               A Default under clause (2) above is not an Event of Default until
the Trustee notifies the Company, or the Holders of at least 25% in aggregate
Principal Amount of the Outstanding Securities of such series notify the Company
and the Trustee, of the Default and the Company does not cure such Default
within the time specified in clause (2) above after receipt of such notice. Any
such notice must specify the Default, demand that it be remedied and state that
such notice is a "Notice of Default."

        SECTION VI.2 Acceleration. If an Event of Default with respect to
Securities of any series at the time Outstanding (other than an Event of Default
specified in Section 6.1(3) or (4)) occurs and is continuing, the Trustee by
notice to the Company, or the Holders of at least 25% in aggregate Principal
Amount of the Outstand ing Securities of that series by notice to the Company
and the Trustee, may declare the Principal Amount (or, if any of the Securities
of that series are Discount Securities, such portion of the Principal Amount of
such Securities as may be specified in the terms thereof) of all the Securities
of that series to be immediately due and payable. Upon such a declaration, such
Principal (or portion thereof) shall be due and payable immediately. If an Event
of Default specified in Section 6.1(3) or (4) occurs and is continuing, the
Principal (or portion thereof) of all the Securities of that series shall become
and be imme diately due and payable without any declaration or other act on the
part of the Trustee or any Securityholders. The Holders of a majority in
aggregate Principal Amount of the Out-

                                       37
<PAGE>   46

standing Securities of any series, by notice to the Trustee (and without notice
to any other Securityholder) may rescind an acceleration with respect to that
series and its conse quences if the rescission would not conflict with any
judgment or decree and all existing Events of Default with respect to Securities
of such series have been cured or waived except nonpayment of the Principal (or
portion thereof) of Securities of such series that has become due solely as a
result of such acceleration and if all amounts due to the Trustee under Section
7.7 have been paid. No such rescission shall affect any subsequent Default or
impair any right consequent thereto.

        SECTION VI.3 Other Remedies. If an Event of Default with respect to a
series of Outstanding Securities occurs and is continuing, the Trustee may
pursue any available remedy to (a) collect the payment of the whole amount then
due and payable on such Securities for Principal and interest, with interest
upon the overdue Prin cipal and, to the extent that payment of such interest
shall be legally enforceable, upon overdue installments of interest from the
date such interest was due, at the rate or rates prescribed therefor in such
Securities and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including amounts due the Trustee
under Section 7.7 or (b) enforce the performance of any provision of the
Securities or this Indenture.

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

        SECTION VI.4 Waiver of Past Defaults. The Holders of a majority in
aggregate Principal Amount of the Outstanding Securities of any series, by
notice to the Trustee (and without notice to any other Securityholder), may on
behalf of the Holders of all the Securities of such series and any related
coupons waive an existing Default with respect to such series and its
consequences except (1) an Event of Default described in Section 6.1(1) with
respect to such series or (2) a Default in respect of a provision that under
Section 9.2 cannot be amended without the consent of the Holder of each
Outstanding Security of such series affected. When a Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other Default
or impair any consequent right.

        SECTION VI.5 Control by Majority. The Holders of a majority in aggregate
Principal Amount of the Outstanding Securities of any series may direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or of exercising any trust or power conferred on the Trustee with
respect to the Securities of such series. However, the Trustee may refuse to
follow any direction that conflicts with 


                                       38
<PAGE>   47

law or this Indenture or that the Trustee determines in good faith is unduly
prejudicial to the rights of other Securityholders or would involve the Trustee
in personal liability.

        SECTION VI.6 Limitation on Suits. A Holder of any Security of any series
or any related coupons may not pursue any remedy with respect to this Indenture
or the Securities unless:

               (1 the Holder gives to the Trustee written notice stating that an
        Event of Default with respect to the Securities of that series is
        continuing;

               (2 the Holders of at least 25% in aggregate Principal Amount of
        the Outstanding Securities of that series make a written request to the
        Trustee to pursue the remedy;

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

               (4 the Trustee does not comply with the request within 60 days
        after receipt of the notice, the request and the offer of security or
        indemnity; and

               (5 the Holders of a majority in aggregate Principal Amount of the
        Outstanding Securities of that series do not give the Trustee a
        direction incon sistent with such request during such 60-day period.

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

        SECTION VI.7 Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right, which is absolute and
unconditional, of any Holder of any Security or coupon to receive payment of the
Principal of and (subject to Section 2.13) interest on such Security or payment
of such coupon on the Stated Maturity or Maturities expressed in such Security
or coupon (or, in the case of redemption, on the Redemption Date) held by such
Holder, on or after the respective due dates expressed in the Securities or any
Redemption Date, or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected adversely without
the consent of each such Holder.

        SECTION VI.8 Collection Suit by Trustee. If an Event of Default
described in Section 6.1(1) with respect to Securities of any series occurs and
is continuing, the Trustee may recover judgment in its own name and as trustee
of an express trust against the Company for the whole amount owing with respect
to such series of Securities and the amounts provided for in Section 7.7.

                                       39
<PAGE>   48

        SECTION VI.9 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 (irrespec tive
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
proceeding or otherwise,

               (a) to file and prove a claim for the whole amount of Principal
        and interest owing and unpaid in respect of the Securities and to file
        such other papers or documents as may be necessary or advisable in order
        to have the claims of the Trustee (including any claim for the
        reasonable compensation, expenses, disbursements and advances of the
        Trustee, its agents and counsel and any other amount due the Trustee
        under Section 7.7) and of the Holders of Securities and coupons allowed
        in such judicial proceeding, and

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

and any Custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder of Securities and coupons to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments directly
to the Holders of Securities and coupons, to pay the Trustee any amount due it
for the reasonable compensation, expenses, disburse ments and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7.

        Nothing herein contained shall be deemed to authorize the Trustee or the
holders of Senior Indebtedness to authorize or consent to or accept or adopt on
behalf of any Holder of a Security or coupon any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or coupons or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder of a Security or coupon in any such proceeding.

        SECTION VI.10 Priorities.VI. If the Trustee collects any money pursuant
to this Article 6, it shall pay out the money in the following order and, in
case of the distribution of such money on account of Principal or interest, upon
presentation of the Securities or 


                                       40
<PAGE>   49

coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

        FIRST:  to the Trustee for amounts due under Section 7.7;

        SECOND: to Securityholders for amounts due and unpaid for the Principal
and interest on the Securities and interest evidenced by coupons 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 and coupons for Principal and interest, respectively;
and

        THIRD:  the balance, if any, to the Company.

        The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10. At least 15 days before such
record date, the Company shall mail to each Securityholder and the Trustee a
notice that states the record date, the payment date and amount to be paid.

        SECTION VI.11 Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant (other than the Trustee) in the suit of
an undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 or a suit
by Holders of more than 10% in aggregate Principal Amount of the Outstanding
Securities of any series, or to any suit instituted by any Holder of any
Security or coupon for the enforcement of the payment of the Principal of or
interest on any Security or the payment of any coupon on or after the Stated
Maturity or Maturities expressed in such Security or coupon (or, in the case of
redemption, on or after the Redemption Date).

        SECTION VI.12 Waiver of Stay, Extension or Usury 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 or any usury or other 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.

        SECTION VII.1 Duties of Trustee.

        (a)  If an Event of Default has occurred and is continuing, the Trustee 
shall exercise the rights and powers vested in it by this Indenture and use the
same degree of care and skill in its exercise as a prudent person would exercise
or use under the circum stances in the conduct of his/her own affairs.

        (b) Except during the continuance of an Event of Default with respect to
Securi ties of any series:

               (1   the Trustee need perform only those duties that are 
        specifically set forth in this Indenture and no others; and

               (2 in the absence of bad faith on its part, the Trustee may
        conclusively rely, as to the truth of the statements and the correctness
        of the opinions expressed therein, upon certificates or opinions
        furnished to the Trustee and conforming to the requirements of this
        Indenture. However, with respect to any certificates or opinions
        specifically required to be furnished to the Trustee, the Trustee shall
        examine the certificates and opinions to determine whether or not they
        conform to the requirements of this Indenture.

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

               (1   this paragraph (c) does not limit the effect of paragraph 
        (b) of this Section 7.1;

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

               (3 the Trustee shall not be liable with respect to any action it
        takes or omits to take in good faith in accordance with a direction
        received by it pursuant to Section 6.5 or exercising any trust or power
        conferred upon the Trustee under this Indenture.

                                       42
<PAGE>   51

        (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 7.1.
        (e) The Trustee may refuse to perform any duty or exercise any right or
power or extend or risk its own funds or otherwise incur any financial liability
unless it receives indemnity satisfactory to it against any loss, liability or
expense.

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

        SECTION VII.2 Rights of Trustee. (a) The Trustee may rely on any
document believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.

        (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on such
Officers' Certificate or Opinion of Counsel.

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

        (d) Subject to the provisions of Section 7.1 (c), the Trustee shall not
be liable for any action it takes or omits to take in good faith which it
believes to be authorized or within its rights or powers.

        (e) Subject to the provisions Section 7.1, the Trustee may rely and
shall be protected in acting or refraining from acting upon any resolution,
Officers' Certificate, Opinion of Counsel (or both), Company Order or any other
certificate, statement, instrument, opinion report, notice, request, consent,
order, bond, debenture, note, coupon, security or other paper believed to be
genuine and to have been signed or presented by the proper party or parties.

        (f) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or an assistant secretary of the Company.

        (g) The Trustee may consult with counsel and any written advice or
Opinion of Counsel shall, subject to the provisions of Section 7.1, be full and
complete authorization 

                                       43
<PAGE>   52

and protection in respect of any action taken, suffered or omitted to be taken
by it hereunder in good faith and in reliance thereon in accordance with such
advice or Opinion of Counsel.

        (h) The Trustee shall be under no obligation to exercise any of the
trusts or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
security or indemnity satisfactory to the Trustee against the costs, expenses
and liabilities which might be incurred therein or thereby.

        (i) Prior to the occurrence of an Event of Default hereunder and after
the curing or waiving of all Events of Default, the Trustee shall not be bound
to make any investiga tion into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, appraisal, bond, debenture, note, coupon, security or other
paper or document unless requested in writing to do so by the Holders of not
less than a majority in the aggregate principal amount of the Securities of such
series then Outstanding; provided, that, if the payment within a reasonable time
to the Trustee of the costs, expenses or liabilities likely to be incurred by it
in the making of any such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Indenture, the Trustee may require such indemnity satisfactory to it
against such expense or liabilities as a condition to proceeding; the reasonable
expense of every such investigation shall be paid by the Company.

        (j) 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 not regularly in its employ and the Trustee shall not be responsible
for any misconduct or negligence on the part of any such agent or attorney
appointed with due care by it hereunder.

        SECTION VII.3 Individual Rights of Trustee, etc. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
or coupons and may otherwise deal with the Company or its Affiliates with the
same rights it would have if it were not Trustee. Any Paying Agent, Registrar or
co-registrar or any other agent of the Company may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

        SECTION VII.4 Trustee's Disclaimer. The recitals contained herein and in
the Securities, except the Trustee's certificate of authentication, shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or adequacy of this Indenture or the
Securities or coupons. The Trustee shall not be accountable for the Company's
use of the proceeds from the Securities and, shall not be responsible for any
statement in the registration statement for the Securities under the Securities
Act of 1933, 


                                       44
<PAGE>   53

as amended, or in the Indenture or the Securities or any coupons (other than its
certificate of authentication) or for the determination as to which beneficial
owners are entitled to receive any notices hereunder.

        SECTION VII.5 Notice of Defaults.. If a Default with respect to the
Securities of any series occurs and is continuing and if it is known to a Trust
Officer, the Trustee shall give to each Holder of Securities of such series
notice of such Default in the manner set forth in TIA Section 315(b) within 90
days after it occurs. Except in the case of a Default described in Section
6.1(1) with respect to any Security of such series or a Default in the payment
of any sinking fund installment with respect to any Security of such series, the
Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the
interests of the Holders of Securities of such series.

        SECTION VII.6 Reports by Trustee to Holders. Within 60 days after each
May 15 beginning with the May 15 following the date of this Indenture, the
Trustee shall mail to each Holder of Securities a brief report dated as of such
May 15 that complies with TIA Section 313(a). The Trustee also shall comply with
TIA Section 313(b) and (c).

        A copy of each report at the time of its mailing to Holders of
Securities shall be filed with the SEC and each stock exchange on which the
Securities of that series may be listed. The Company agrees to notify the
Trustee whenever the Securities of a particular series become listed on any
stock exchange and of any delisting thereof.

        SECTION VII.7  Compensation and Indemnity. The Company agrees:

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

               (b) to reimburse the Trustee for all reasonable expenses,
        disburse ments and advances incurred or made by the Trustee in
        accordance with any provision of this Indenture (including the
        reasonable compensation and the expenses, advances 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

               (c) to indemnify the Trustee for, and to hold it harmless
        against, any loss, liability or expense incurred without negligence or
        bad faith on its part, arising out of or in connection with the
        acceptance or adminis tration of this trust, including the costs and
        expenses of defending itself 

                                       45
<PAGE>   54

        against any claim or liability in connection with the exercise or perfor
        mance of any of its powers or duties hereunder.

        To secure the Company's payment obligations in this Section 7.7, the
Trustee shall have a lien prior to the Securities and any coupons on all money
or property held or collected by the Trustee, except that held in trust to pay
the Principal of or interest, if any, on particular Securities or for the
payment of particular coupons.

        The Company's payment obligations pursuant to this Section 7.7 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.1(3) or (4), the expenses are
intended to constitute expenses of administration under any Bankruptcy Law.

        SECTION VII.8 Replacement of Trustee. The Trustee may resign by so
notifying the Company; provided, however, no such resignation shall be effective
until a successor Trustee has accepted its appointment pursuant to this Section
7.8. The Holders of a majority in aggregate Principal Amount of the Outstanding
Securities of any series at the time outstanding may remove the Trustee with
respect to the Securities of such series by so notifying the Trustee and may
appoint a successor Trustee. The Company shall remove the Trustee if:

               (1)  the Trustee fails to comply with Section 7.10;

               (2)  the Trustee is adjudged bankrupt or insolvent;

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

               (4) the Trustee otherwise becomes incapable of acting.

        If the Trustee resigns or is removed or if a vacancy exists in the
office of the Trustee for any reason, with respect to the Securities of one or
more series, the Company shall promptly appoint, by resolution of its Board of
Directors, a successor Trustee with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed
with respect to the Securities of one or more or all of such series and that at
any time there shall be only one Trustee with respect to the Securities of any
series).

        In the case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee shall deliver a written
acceptance of its appoint ment to the retiring Trustee and to the Company.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective and the successor Trustee shall have all the

                                       46
<PAGE>   55

rights, powers and duties of the Trustee under this Indenture. The successor
Trustee shall mail a notice of its succession to Holders of Securities of the
particular series with respect to which such successor Trustee has been
appointed. The retiring Trustee shall promptly transfer all property held by it
as Trustee to the successor Trustee, subject to the lien provided for in Section
7.7.

        In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees as co-Trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appoint ment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, subject,
nevertheless, to its lien, if any, provided for in Section 7.7.

        If a successor Trustee with respect to the Securities of any series does
not take office within 30 days after the retiring Trustee resigns or is removed,
the retiring Trustee, the Company or the Holders of a majority in aggregate
Principal Amount of the Outstand ing Securities of such series at the time
outstanding may petition any court of competent jurisdiction for the appointment
of a successor Trustee with respect to the Securities of such series.

                                       47
<PAGE>   56

        If the Trustee fails to comply with Section 7.10, any Holder of a
Security of such series may petition any court of competent jurisdiction for the
removal of such Trustee and the appointment of a successor Trustee.

        SECTION VII.9 Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation, the resulting,
surviving or transferee corporation without any further act shall be the
successor Trustee.

        SECTION VII.10 Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA Section 310(a)(1) and 310(a)(5). The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition. The Trustee shall
comply with TIA Section 310(b), including the optional provision permitted by
the second sentence of TIA Section 310(b)(9). In determining whether the Trustee
has conflicting interests as defined in TIA Section 310(b)(1), the provisions
contained in the proviso to TIA Section 310(b)(1) shall be deemed incorporated
herein.

        SECTION VII.11 Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                                   ARTICLE VIII

Trustee cash sufficient to pay at Stated Maturity the Principal Amount of all
Principal of and interest on Outstanding Securities or all Outstanding
Securities of such series (other than Securities replaced pursuant to Section
2.9), and if in either case the Company pays all other sums payable hereunder by
the Company, then this Indenture shall, subject to Section 7.7, cease to be of
further effect as to all Outstanding Securities or all Outstanding Securities of
any series, as the case may be. The Trustee shall join in the execution of a
document prepared by the Company acknowledging satisfaction and discharge of

being required to make any such return, may at the expense and direction of the
Company cause to be published once in an Authorized Newspaper in each Place of
Payment of or mail to each such Holder notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication or mailing, any unclaimed money then remaining
wilt be returned to the Company. After return to the Company, Holders entitled
to the money must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another person.

        SECTION VIII.3 Option to Effect Defeasance or Covenant Defeasance.
Unless otherwise specified as contemplated by Section 2.3(a) with respect to
Securities of a particular series, the Company, may at its option, by Board
Resolution, at any time, with respect to any series of Securities, elect to have
either Section 8.4 or Section 8.5 be applied to all of the outstanding
Securities of any series (the "Defeased Securities"), upon compliance with the
conditions set forth in this Article VIII.

        SECTION VIII.4 Defeasance and Discharge. Upon the Company's exercise
under Section 8.3 of the option applicable to this Section 8.4, the Company
shall be deemed to have been discharged from its obligations with respect to the
Defeased Securities on the date the conditions set forth below in Section 8.6
are satisfied (hereinafter "defeasance"). For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the defeased Securities, which shall thereafter be
deemed to be "outstand ing" only for the purposes of Sections 2.4, 2.5,2.6, 2.9,
2.11, 2.12, 4.1, 4.5, 6.6, 6.7, 7.7, 7.8 and 8.2 of this Indenture and to have
satisfied all its other obligations under such series of Securities and this
Indenture insofar as such series of Securities are concerned (and the Trustee,
at the expense of the Company, and, upon written request, shall execute proper
instruments acknowledging the same). Subject to compliance with this Article
VIII, the Company may

                                       49
<PAGE>   58

exercise its option under this Section 8.4 notwithstanding the prior exercise of
its option under Section 8.5 with respect to a series of Securities.

        SECTION VIII.5 Covenant Defeasance. Upon the Company's exercise under
Section 8.3 of the option applicable this Section 8.5, the Company shall be
released from its obligations under Sections 4.2 and 4.3 and Article V and such
other provisions as may be provided as contemplated by Section 2.3(a) with
respect to Securities of a particular series and with respect to the Defeased
Securities on and after the date the conditions set forth below in Section 8.6
are satisfied (hereinafter "covenant defeasance"), and the Defeased Securities
shall thereafter be deemed to be not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences if any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to the Defeased
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such Section or
Article described in this Section 8.5, whether directly or indirectly, by reason
of any reference elsewhere herein to any such Section or Article described in
this Section 8.5 or by reason of any reference in any such Section or Article
described in this Section 8.5 to any other provisions herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 6.1 but, except as specified above, the remainder of
this Indenture and such Defeased Securities shall be unaffected thereby.

        SECTION VIII.6 Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of either Section 8.4 or
Section 8.5 to a series of outstanding Securities.

        (a) The Company shall have irrevocably deposited with the Trustee, in

predetermined and certain income to accrue thereon without consideration of any
reinvestment thereof, be sufficient to pay when due the Principal of, and
interest to Stated Maturity (or redemption) on, the Debt Securities of such
series.

        (b) The Company shall (i) have delivered an opinion of counsel that the
Holders of the Securities of such series will not recognize income, gain or loss
for United States Federal income tax purposes as a result of such defeasance,
and will be subject to tax in the same manner as if no defeasance and discharge
or covenant defeasance, as the case 


                                       50
<PAGE>   59

may be, had occurred or (ii) in the case of an election under Section 8.4 the
Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that (A) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (B) since the date this Indenture was first

        created prior to the execution of such supple mental indenture and
        entitled to the benefit of such provision nor (B) modify the rights of
        the Holder of any such Security with respect to such provision; or

               (8)  to secure the Securities; or

               (9) to make any other change that does not adversely affect the
        rights of any Securityholder.

        SECTION IX.2 Supplemental Indentures with Consent of Holders. With the
written consent of the Holders of at least a majority in aggregate Principal
Amount of the Outstanding Securities of each series affected by such
supplemental indenture, the Company and the Trustee may amend this Indenture or
the Securities of any series or 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 such
series and any related coupons under this Indenture; provided, however, that no
such amendment or supplemental indenture shall, without the consent of the
Holder of each Outstanding Security affected thereby:

               (1) change the Stated Maturity of the Principal of, or any
        installment of Principal or interest on, any such Security, or reduce
        the Principal Amount thereof or the rate of interest thereon or any
        premium payable upon redemption thereof or reduce the amount of
        Principal of any such Discount Security that would be due and payable
        upon a declaration of acceleration of maturity thereof pursuant to
        Section 6.2, or change the Place of Payment, or change the coin or
        currency in which, any Principal of, or any installment of interest on,
        any such Security is payable, or impair the right to institute suit for
        the enforcement of any such payment on or after the Stated Maturity
        thereof (or, in the case of redemption, on or after the Redemption
        Date);

               (2) reduce the percentage in Principal Amount of the Outstanding
        Securi ties of any series, the consent of whose Holders is required for

                                       52
<PAGE>   61

        any such amend ment or supplemental indenture, or the consent of whose
        Holders is required for any waiver (of compliance with certain
        provisions of this Indenture or certain de faults hereunder and their
        consequences) with respect to the Securities of such series provided for
        in this Indenture; or

               (3) modify any of the provisions of this Section, Section 6.4 or
        6.7, except to increase the percentage of Outstanding Securities of such
        series required for such actions 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 the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment or
supplemental indenture, but it shall be sufficient if such consent approves the
substance thereof.

        After an amendment or supplemental indenture under this Section 9.2
becomes effective, the Company shall mail to each Holder of the particular
Securities affected thereby a notice briefly describing the amendment.

        SECTION IX.3 Compliance with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall comply with the TIA as then in
effect.

        SECTION IX.4 Revocation and Effect of Consents, Waivers and Actions.
Until an amendment or waiver with respect to a series of Securities becomes
effective, a consent to it or any other action by a Holder of a Security of that
series hereunder is a continuing consent by the Holder and every subsequent
Holder of that Security or portion of that Security that evidences the same
obligation as the consenting Holder's Security, even if notation of the consent,
waiver or action is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent, waiver or action as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the Company or an agent of the Company certifies to the
Trustee that the consent of the requisite aggregate Principal Amount of the
Securities of that series has been obtained. After an amendment, waiver or
action becomes effective, it shall bind every Holder of Securities of that
series.

        The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment or
waiver with respect to 

                                       53
<PAGE>   62

a series of Securities. If a record date is fixed, then notwithstanding the
first two sen tences of the immediately preceding paragraph, those persons who
were Holders of Securities of that series at such record date (or their duly
designated proxies), and only those persons, shall be entitled to revoke any
consent previously given, whether or not such persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date.

        SECTION IX.5 Notation on or Exchange of Securities. Securities of any
series authenticated and delivered after the execution of any supplemental
indenture with respect to such series pursuant to this Article may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such supplemental indenture. If the Company shall so
determine, new Securities of such series so modified as to conform, in the
opinion of the Trustee and the Board of Directors, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for outstanding Securities of that series.

        SECTION IX.6 Trustee to Sign Supplemental Indentures. The Trustee shall
sign any supplemental indenture authorized pursuant to this Article 9 if the
amendment does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may, but need not, sign it.
In signing such amendment, the Trustee shall be entitled to receive, and
(subject to the provisions of Section 7.1) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

        SECTION IX.7 Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby, except
to the extent otherwise set forth thereon.


                                     ARTICLE X

                                   SINKING FUNDS

        SECTION X.1 Applicability of Article. The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a
series, except as otherwise specified as contemplated by Section 2.3(a) for
Securities of such series.

                                       54
<PAGE>   63

        The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 10.2. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of the Securities of such
series.

        SECTION X.2 Satisfaction of Sinking Fund Payments with Securities. The
Company (1) may deliver Outstanding Securities of a series with the same issue
date, interest rate and Stated Maturity (other than any previously called for
redemption), together in the case of any Bearer Securities of such series with
the same issue date, interest rate and Stated Maturity with all unmatured
coupons appertaining thereto, and (2) may apply as a credit Securities of a
series with the same issue date, interest rate and Stated Maturity which have
been redeemed either at the election of the Company pursuant to the terms of
such Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Securities, in each case in satisfaction
of all or any part of any mandatory sinking fund payment with respect to the
Securities of such series with the same issue date, interest rate and Stated
Maturity; provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

        SECTION X.3 Redemption of Securities for Sinking Fund. Not less than 60
days (or such shorter period as shall be acceptable to the Trustee) prior to
each sinking fund payment date for any series of Securities, the Company will
deliver to the Trustee an Officers' Certificate specifying the amount of the
next ensuing sinking fund payment for that series pursuant to the terms of that
series, the portion thereof, if any, which is to be satisfied by payment of cash
and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities of that series pursuant to Section 10.2 and will also
deliver to the Trustee any Securities to be so delivered. Not less than 30 days
before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 3.2 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 3.3. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections 3.4
and 3.6.

                                    ARTICLE XI

<PAGE>   64

                         ACTIONS OF HOLDERS OF SECURITIES

        SECTION XI.1 Purposes for which Meetings may be Called. A meeting of
Holders of Securities of any series may be called at any time and from time to
time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such
series.

        SECTION XI.2 Call, Notice and Place of Meetings. (a) The Trustee may at
any time call a meeting of Holders of Securities of any series for any purpose
specified in Section 11.1, to be held at such time and at such place in the
Borough of Manhattan, The City of New York or, for a series of Securities issued
as Bearer Securities, in London as the Trustee shall determine or, with the
approval of the Company, at any other place. Notice of every meeting of Holders
of Securities of any series, setting forth the time and the place of such
meeting and in general terms the action proposed to be taken at such meeting,
shall be given, in the manner provided in Section 12.2, not less than 21 nor
more than 180 days prior to the date fixed for the meeting.

        (b) In case at any time the Company or the Holders of at least 10% in
Principal Amount of the Outstanding Securities of any series shall have
requested the Trustee to call a meeting of the Holders of Securities of such
series for any purpose specified in Section 11.1, by written request setting
forth in reasonable detail the action proposed to be taken at the meeting, and
the Trustee shall not have made the first publication of the notice of such
meeting within 21 days after receipt of such request or shall not thereafter
proceed to cause the meeting to be held as provided herein, then the Company or
the Holders of Securities of such series in the amount above specified, as the
case may be, may determine the time and the place in the Borough of Manhattan,
The City of New York, or for a series of Securities issued as Bearer Securities,
in London, or in such other place as shall be determined and approved by the
Company, for such meeting and may call such meeting for such purposes by giving
notice thereof as provided in subsection (a) of this Section 11.2.

        SECTION XI.3 Persons Entitled to Vote at Meetings. To be entitled to
vote at any meeting of Holders of Securities of any series, a person shall be
(1) a Holder of one or more Outstanding Securities of such series, or (2) a
person appointed by an instrument in writing as proxy for a Holder or Holders of
one or more Outstanding Securities of such series by such Holder or Holders. The
only persons who shall be entitled to be present or to speak at any meeting of
Holders of Securities of any series shall be the persons entitled to vote at
such meeting and their counsel, any representatives of the Trustee and its
counsel and any representatives of the Company and its counsel.

                                       56
<PAGE>   65

        SECTION XI.4 Quorum; Action. The persons entitled to vote a majority in
Principal Amount of the Outstanding Securities of a series shall constitute a
quorum for a meeting of Holders of Securities of such series. In the absence of
a quorum within 30 minutes of the time appointed for any such meeting, the
meeting shall, if convened at the request of Holders of Securities of such
series, be dissolved. In any other case, the meeting may be adjourned for a
period determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period determined by the
chairman of the meeting prior to the adjournment of such adjourned meeting.
Notice of the reconvening of any adjourned meeting shall be given as provided in
Section 11.2(a), except that such notice need be given only once not less than
five days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an adjourned meeting shall state expressly the
percentage, as provided above, of the principal amount of the Outstanding
Securities of such series which shall constitute a quorum.

        Except as limited by the proviso to Section 9.2, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of a
majority in Principal Amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any
resolution with respect to any request, demand, authoriza tion, direction,
notice, consent, waiver or other action which this Indenture expressly provides
may be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in Principal Amount of the Outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified percentage in Principal Amount of the Outstanding Securities
of that series.

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

        SECTION XI.5 Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section
11.7 and the appointment of any proxy shall be proved in the manner specified in
Section 11.7 or by 

                                       57
<PAGE>   66

having the signature of the person executing the proxy witnessed or guaranteed
by any trust company, bank or banker authorized by Section 11.7 to certify to
the holding of Bearer Securities. Such regulations may provide that written
instruments appointing proxies, regular on their face, may be presumed valid and
genuine without the proof specified in Section 11.7 or other proof.

        (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 11.2(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the persons entitled to vote a majority in Principal Amount of the
Outstanding Securities of such series represented at the meeting.

        (c) At any meeting each Holder of a Security of such series or proxy
shall be entitled to vote with respect to the Outstanding Securities of such
series held or repre sented by him; provided, however, that no vote shall be
cast or counted at any meeting in respect to any Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

        (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 11.2 at which a quorum is present may be adjourned from time
to time by persons entitled to vote a majority in Principal Amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

        SECTION XI.6 Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed signatures of
the Holders of Securities of such series or of their representatives by proxy
and the Principal Amounts and serial numbers of the Outstanding Securities of
such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the facts setting forth a
copy of the notice of the meeting and showing that said notice was given as
provided in Section 11.2 and, if applicable, Section 11.4. Each copy shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one 

                                       58
<PAGE>   67

such copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

        SECTION XI.7 Actions of Holders Generally. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders
in person or by an agent duly appointed in writing. If Securities of a series
are issuable as Bearer Securities, any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of such series may, alternatively, be embodied in
and evidenced by the record of Holders of Securities of such series voting in
favor thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of this Article, or a combination of such instru
ments and any such record. Except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments or record or
both are delivered to the Trustee and, where it is hereby expressly required, to
the Company. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to Section 7.1)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section. The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 11.6.

        (b) The fact and date of the execution by any person of any such
instrument or writing, or the authority of the persons executing the same, may
be proved in any reasonable manner which the Trustee deems sufficient.

        (c) The Principal Amount and serial numbers of Registered Securities
held by the person, and the date of holding the same, shall be proved by the
books of the Registrar.

        (d) The Principal Amount and serial numbers of Bearer Securities held by
any person, and the date of holding the same, may be proved by the production of
such Bearer Securities or by a certificate executed by any trust company, bank,
banker or other depositary, wherever situated, as depositary, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such person had on deposit with such depositary, or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate or affidavit of the person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the 

                                       59
<PAGE>   68

Trustee by some other person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding. The Principal Amount and serial numbers of Bearer Securities held
by any person, and the date of holding the same, may also be proved in any other
manner which the Trustee deems sufficient.

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

        (f) If the Company shall solicit from the Holders any request, demand,
authoriza tion, direction, notice, consent, waiver or other act in accordance
with this Section, the Company may, at its option, by or pursuant to an
Officers' Certificate delivered to the Trustee, fix in advance a record date for
the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or such other act, but the
Company shall have no obligation to do so. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other act
may be given before or after such record date, but only the Holders of record at
the close of business on such record date shall be deemed to be Holders for the
purposes of determin ing whether Holders of the requisite percentage of
Outstanding Securities or Outstanding Securities of a series, as the case may
be, have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other act, and for that
purpose the Outstanding Securities or Outstanding Securities of the series, as
the case may be, shall be computed as of such record date; provided, that no
such authorization, agreement or consent by the Holders on the record date shall
be deemed effective unless such request, demand, authorization, direction,
notice, consent, waiver or other act shall become effective pursuant to the
provisions of clause (a) of this Section 11.7 not later than six months after
the record date.

        SECTION XII.2 Notices. Any notice or communication shall be in writing
and delivered in person or mailed by first-class mail, postage prepaid;
provided, that any notice or communication by and among the Trustee and the
Company may be made by telecopy or other commercially accepted electronic means
and shall be effective upon receipt thereof and shall be confirmed in writing,
mailed by first-class mail, postage prepaid, addressed as follows:

               if to the Company:

               Litton Industries, Inc.
               21240 Burbank Boulevard
               Woodland Hills, California  91367

               Attention: Chief Financial Officer


               if to the Trustee:

               The Bank of New York
               101 Barclay Street, Floor 21 West
               New York, New York 10286

               Attention:  Corporate Trust Administration

        The Company or the Trustee by notice to the other may designate
additional or different addresses for subsequent notices or communications.

        Any notice or communication given to a Holder of Registered Securities
shall be mailed to such Securityholder at the Securityholder's address as it
appears on the registra tion books of the Registrar and shall be sufficiently
given if so mailed within the time prescribed. Notice shall be sufficiently
given to Holders of Bearer Securities if published in an Authorized Newspaper in
The City of New York and in such other city or cities as may be specified in
such Securities on a Business Day at least twice, the first such publication to
be not earlier than the earliest date, and not later than the latest date,
prescribed for the giving of such notice.

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

                                       61
<PAGE>   70

        Failure to mail a notice or communication to a Securityholder or any
defect in it shall not affect its sufficiency with respect to other Holders of
Securities of the same series. If a notice or communication is mailed in the
manner provided above, it is duly given, whether or not received by the
addressee.

        If the Company mails a notice or communication to the Holders of
Securities of a particular series, it shall mail a copy to the Trustee and each
Registrar, co-registrar or Paying Agent, as the case may be, with respect to
such series.

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

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

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

        SECTION XII.3 Communication by Holders with Other Holders..

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

replaced (plus improvements on the property); and

                                (9) any Lien not permitted by clauses (1)

restrictions and the aggregate Value (as defined) of existing Sale and Leaseback
Transactions (as defined) which would be subject to the restrictions of Section
3(k)(ii) herein but for this clause (9), does not at any time exceed 15% of
Consolidated Net Tangible Assets (as defined).

                              (ii) 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 Notes) because such Liens would be of such character that no
        violation of any of the provisions of Section 3(k)(i) herein 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

        (whether by redemption, defeasance, repurchase, or otherwise) an amount
        equal to the Value of such Sale and Leaseback Transaction.

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 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

                        (7) any Lien in favor of the United States of America or
any State thereof or any other country, or any agency, instrumentality or
political subdivision of any of 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

                        (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 (as defined) of existing Sale and Leaseback Transactions (as
defined) which would be subject to the restrictions of Section 3(k)(ii) herein
but for this clause (9), does not at any time exceed 15% of Consolidated Net
Tangible Assets (as defined).

                  (ii) 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 Notes) because such Liens
would be of such character that no violation of any of the provisions of Section
3(k)(i) herein 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 (as defined) (whether by redemption, defeasance,
repurchase, or otherwise) an amount equal to the Value of such Sale and
Leaseback Transaction.

                  extendable or renewable at the option of the obligor to a date

                  being determined) and (2) all goodwill, tradenames,
                  trademarks, patents, unamortized debt discount and expense and
                  other like intangible assets, all as set forth on the most
                  recent balance sheet of the Company and its consolidated
                  subsidiaries and determined in accordance with generally
                  accepted accounting principles.

                  States of America, which, in the opinion of the Board of
                  Directors, is of material importance to the business of the
                  Company and its Subsidiaries taken as a whole, but no such
                  manufacturing facility, or portion thereof, shall be deemed of
                  material importance if its gross book value (before deducting
                  accumulated depreciation) is less than 2% of Consolidated Net

                  with any individual, corporation, partnership, joint venture,
                  association, joint-stock company, trust, unincorporated
                  organization or government or any agency or political

                  or improvement, or the commencement of commercial operation of
                  the Restricted Property, and (4) arrangements pursuant to any

                 provision of law with an effect similar to the former Section
                  168(f)(8) of the Internal Revenue Code of 1954.

                        Only for purposes of this Section 3(k), "Subsidiary" of
                  any specified corporation means (i) a corporation, a majority
                  of whose shares, interests, rights to purchase, warrants,
                  options, participations or other equivalents of or interests
                  (however designated) in stock with voting power, under
                  ordinary circumstances, to elect directors is, at the date of
                  determination, directly or indirectly owned by the Company, by
                  one or more Subsidiaries of the Company or by the Company and
                  one or more Subsidiaries of the Company or (ii) a partnership
                  in which the Company or a Subsidiary of the Company is at the
                  date of determination, a general partner of such partnership,
                  or (iii) any other Person (other than a corporation or a
                  partnership) in which the Company, a Subsidiary of the Company
                  or the Company and one or more Subsidiaries of the Company,
                  directly or indirectly, at the date of determination, has (x)
                  at least a majority ownership interest or (y) the power to
                  elect or direct the election of a majority of the directors or
                  other governing body of such Person.

                        "Value" means, with respect to a Sale and Leaseback
                  Transaction, an amount equal to the present value of the lease
                  payments with respect to the term of the lease remaining on
                  the date as of which the amount is being determined, without
                  regard to any renewal or extension options contained in the
                  lease, discounted at the weighted average interest rate on the
                  Notes of all series (including the effective interest rate on
                  any original issue discount Notes) which are outstanding on
                  the effective date of such Sale and Leaseback Transaction and
                  which have the benefit of Section 3(k)(ii) herein.

        (4) Miscellaneous.

             (a) Capitalized terms used herein and not otherwise defined shall
have the meanings specified in the Indenture.

                                (D) in the case of an Absolute Rate Auction, the
                        rate of interest per annum (specified to the nearest
                        1/10,000th of 1%) (the "MONEY MARKET ABSOLUTE RATE")
                        offered for each such Money Market Loan, and

                                (E) the identity of the quoting Bank.

           A Money Market Quote may set forth up to five separate offers by the
           quoting Bank with respect to each Interest Period specified in the
           related Invitation for Money Market Quotes.

                        (iii) Any Money Market Quote shall be disregarded if it:

                                (A) is not substantially in conformity with
                        Exhibit D hereto or does not specify all of the
                        information required by subsection (d)(ii);

                                (B) contains qualifying, conditional or similar
                        language (other than the limitation set forth in clause
                        (ii)(B)(z) above);

<PAGE>   25


                                (C) proposes terms other than or in addition to
                        those set forth in the applicable Invitation for Money
                        Market Quotes; or

                                (D) arrives after the time set forth in
                        subsection (d)(i).

            (e) Notice to Borrower. The Agent shall promptly notify the Borrower
of the terms (x) of any Money Market Quote submitted by a Bank that is in
accordance with subsection (d) and (y) of any Money Market Quote that amends,
modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market Quote Request. Any
such subsequent Money Market Quote shall be disregarded by the Agent unless such
subsequent Money Market Quote is submitted solely to correct a manifest error in
such former Money Market Quote. The Agent's notice to the Borrower shall specify
(A) the aggregate principal amount of Money Market Loans for which offers have
been received for each Interest Period specified in the related Money Market
Quote Request, (B) the respective principal amounts and Money Market Margins or
Money Market Absolute Rates, as the case may be, so offered and (C) if
applicable, limitations on the aggregate principal amount of Money Market Loans
for which offers in any single Money Market Quote may be accepted.

            (f) Acceptance and Notice by Borrower. Not later than 10:30 A.M.
(New York City time) on (x) the third Euro-Dollar Business Day prior to the
proposed date of Borrowing, in the case of a LIBOR Auction or (y) the proposed
date of Borrowing, in the case of an Absolute Rate Auction (or, in either case,
such other time or date as the Borrower and the Agent shall have mutually agreed
and shall have notified to the Banks not later than the date of the Money Market
Quote Request for the first LIBOR Auction or Absolute Rate Auction for which
such change is to be effective), the Borrower shall notify the Agent of its
acceptance or non-acceptance of the offers so notified to it pursuant to
subsection (e). In the case of acceptance, such notice (a "NOTICE OF MONEY
MARKET BORROWING") shall specify the aggregate principal amount of offers for
each Interest Period that are accepted. The Borrower may accept any Money Market
Quote in whole or in part; provided that:

                (i) the aggregate principal amount of each Money Market
        Borrowing may not exceed the applicable amount set forth in the related
        Money Market Quote Request,

                (ii) the principal amount of each Money Market Borrowing must be
        $15,000,000 or a larger multiple of $1,000,000,



                                       21

<PAGE>   26


                (iii) acceptance of offers may only be made on the basis of
        ascending Money Market Margins or Money Market Absolute Rates, as the
        case may be, and

                (iv) the Borrower may not accept any offer that is described in
        subsection (d)(iii) or that otherwise fails to comply with the
        requirements of this Agreement.

            (g) Allocation by Agent. If offers are made by two or more Banks
with the same Money Market Margins or Money Market Absolute Rates, as the case
may be, for a greater aggregate principal amount than the amount in respect of
which such offers are accepted for the related Interest Period, the principal
amount of Money Market Loans in respect of which such offers are accepted shall
be allocated by the Agent among such Banks as nearly as possible (in multiples
of $1,000,000, as the Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determinations by the Agent of the amounts of
Money Market Loans shall be conclusive in the absence of manifest error.

           SECTION 2.04. Notice to Banks; Funding of Loans. (a) Upon receipt of
a Notice of Borrowing, the Agent shall promptly notify each Bank of the contents
thereof and of such Bank's share (if any) of such Borrowing and such Notice of
Borrowing shall not thereafter be revocable by the Borrower.

            (b) Not later than 12:00 Noon (New York City time) on the date of
each Borrowing, each Bank participating therein shall make available its share
of such Borrowing, in Federal or other funds immediately available in New York
City, to the Agent at its address referred to in Section 9.01. Unless the Agent
determines that any applicable condition specified in Article 3 has not been
satisfied, the Agent will make the funds so received from the Banks available to
the Borrower at the Agent's aforesaid address.

            (c) Unless the Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsection (b) of this Section 2.04 and the Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Agent, such Bank and, if such Bank shall fail to do
so within one Domestic Business Day, the Borrower severally agree to repay to
the Agent forthwith on demand such corresponding amount together with interest
thereon, for each day from the date such amount is made available to the
Borrower until the date such amount is repaid to the Agent, at the Federal Funds
Rate. If such



                                       22
<PAGE>   27



Bank shall repay to the Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Loan included in such Borrowing for purposes of
this Agreement.

           SECTION 2.05. Registry; Notes. (a) The Agent shall maintain a
register (the "REGISTER") on which it will record the Commitment of each Bank,
each Loan made by such Bank and each repayment of any Loan made by such Bank.
Any such recordation by the Agent on the Register shall be presumptively
correct, absent manifest error. Failure to make any such recordation, or any
error in such recordation, shall not affect the Borrower's obligations
hereunder.

            (b) The Borrower hereby agrees that, promptly upon the request of
any Bank at any time, the Borrower shall deliver to such Bank a duly executed
Note, in substantially the form of Exhibit A hereto, payable to the order of
such Bank and representing the obligation of the Borrower to pay the unpaid
principal amount of the Loans made by such Bank, with interest as provided
herein on the unpaid principal amount from time to time outstanding.

            (c) Each Bank shall record the date, amount and maturity of each
Loan made by it and the date and amount of each payment of principal made by the
Borrower with respect thereto, and each Bank receiving a Note pursuant to this
Section, if such Bank so elects in connection with any transfer or enforcement
of any Note, may endorse on the schedule forming a part thereof appropriate
notations to evidence the foregoing information with respect to each such Loan
then outstanding; provided that the failure of such Bank to make any such
recordation or endorsement shall not affect the obligations of the Borrower
hereunder or under the Notes. Such Bank is hereby irrevocably authorized by the
Borrower so to endorse any Note and to attach to and make a part of any Note a
continuation of any such schedule as and when required.

            (d) Each Bank may, by notice to the Borrower and the Agent, request
that its Loans of a particular type be evidenced by a separate Note in an amount
equal to the aggregate unpaid principal amount of such Loans. Each such Note
shall contain appropriate modifications to reflect the fact that it evidences
solely Loans of the relevant type. Each reference in this Agreement to the
"Note" of such Bank shall be deemed to refer to and include any or all of such
Notes, as the context may require.

           SECTION 2.06. Maturity of Loans. (a) Each Committed Loan shall
mature, and the principal amount thereof shall be due and payable (together with
interest accrued thereon), on the Termination Date.



                                       23

<PAGE>   28



            (b) Each Money Market Loan included in any Money Market Borrowing
shall mature, and the principal amount thereof shall be due and payable
(together with interest accrued thereon), on the last day of the Interest Period
applicable to such Borrowing.

           SECTION 2.07. Interest Rates. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for such day. Such interest shall be payable quarterly in arrears on each
Quarterly Payment Date and at maturity. Any overdue principal of or interest on
any Base Rate Loan shall bear interest, payable on demand, for each day until
paid at a rate per annum equal to the sum of 2% plus the rate otherwise
applicable to Base Rate Loans for such day.

            (b) Each CD Loan shall bear interest on the outstanding principal
amount thereof, for each day during each Interest Period applicable thereto, at
a rate per annum equal to the sum of the CD Margin for such day plus the
Adjusted CD Rate applicable to such Interest Period; provided that if any CD
Loan shall, as a result of clause (2)(b) of the definition of Interest Period,
have an Interest Period of less than 30 days, such CD Loan shall bear interest
during such Interest Period at the rate applicable to Base Rate Loans during
such period. Such interest shall be payable for each Interest Period on the last
day thereof and, if such Interest Period is longer than 90 days, at intervals of
90 days after the first day thereof. Any overdue principal of or interest on any
CD Loan shall bear interest, payable on demand, for each day until paid at a
rate per annum equal to the sum of 2% plus the higher of (i) the sum of the CD
Margin for such day plus the Adjusted CD Rate applicable to such Loan on the day
before such payment was due and (ii) the rate applicable to Base Rate Loans for
such day.

           The "ADJUSTED CD RATE" applicable to any Interest Period means a rate
per annum determined pursuant to the following formula:


                                CDBR                
       ACDR =   [   ------------------------------ ]*  +  AR
                             1.00 - DRP             

       ACDR =  Adjusted CD Rate
       CDBR =  CD Base Rate
        DRP =  Domestic Reserve Percentage
         AR =  Assessment Rate



- --------
        *The amount in brackets being rounded upward, if necessary, to the next
higher 1/100 of 1%



                                       24

<PAGE>   29

           The "CD BASE RATE" applicable to any Interest Period is the rate of
interest determined by the Agent to be the average (rounded upward, if
necessary, to the next higher 1/100 of 1%) of the prevailing rates per annum bid
at 10:00 A.M. (New York City time) (or as soon thereafter as practicable) on the
first day of such Interest Period by two or more New York certificate of deposit
dealers of recognized standing for the purchase at face value from each CD
Reference Bank of its certificates of deposit in an amount comparable to the
principal amount of the CD Loan of such CD Reference Bank to which such Interest
Period applies and having a maturity comparable to such Interest Period.

           "DOMESTIC RESERVE PERCENTAGE" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement (including without limitation any
basic, supplemental or emergency reserves) for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of new non-personal time deposits in dollars in New York City having a
maturity comparable to the related Interest Period and in an amount of $100,000
or more. The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Domestic Reserve Percentage.

           "ASSESSMENT RATE" means for any day the annual assessment rate in
effect on such day which is payable by a member of the Bank Insurance Fund
classified as adequately capitalized and within supervisory subgroup "A" (or a
comparable successor assessment risk classification) within the meaning of 12
C.F.R. Section 327.4(a) (or any successor provision) to the Federal Deposit
Insurance Corporation (or any successor) for such Corporation's (or such
successor's) insuring time deposits at offices of such institution in the United
States. The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Assessment Rate.

            (c) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such
day plus the London Interbank Offered Rate applicable to such Interest Period.
Such interest shall be payable for each Interest Period on the last day thereof
and, if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

           The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
each of the Euro-Dollar Reference Banks in the London interbank market at



                                       25

<PAGE>   30

approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Loan of such Euro-Dollar Reference Bank to
which such Interest Period is to apply and for a period of time comparable to
such Interest Period.

            (d) Any overdue principal of or interest on any Euro-Dollar Loan
shall bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the sum of 2% plus the higher of (i) the sum of the
Euro-Dollar Margin for such day plus the London Interbank Offered Rate
applicable to such Loan on the day before such payment was due and (ii) the
Euro-Dollar Margin for such day plus the quotient obtained (rounded upward, if
necessary, to the next higher 1/100 of 1%) by dividing (x) the average (rounded
upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per
annum at which one day (or, if such amount due remains unpaid more than three
Euro-Dollar Business Days, then for such other period of time not longer than
three months as the Agent may select) deposits in dollars in an amount
approximately equal to such overdue payment due to each of the Euro-Dollar
Reference Banks are offered to such Euro-Dollar Reference Bank in the London
interbank market for the applicable period determined as provided above by (y)
1.00 minus the Euro-Dollar Reserve Percentage (or, if the circumstances
described in clause (a) or (b) of Section 8.01 shall exist, at a rate per annum
equal to the sum of 2% plus the rate applicable to Base Rate Loans for such
day).

            (e) Subject to Section 8.01(a), each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the sum of the London
Interbank Offered Rate for such Interest Period (determined in accordance with
Section 2.07(c) as if the related Money Market LIBOR Borrowing were a
Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the
Bank making such Loan in accordance with Section 2.03. Each Money Market
Absolute Rate Loan shall bear interest on the outstanding principal amount
thereof, for the Interest Period applicable thereto, at a rate per annum equal
to the Money Market Absolute Rate quoted by the Bank making such Loan in
accordance with Section 2.03. Such interest shall be payable for each Interest
Period on the last day thereof and, if such Interest Period is longer than three
months, at intervals of three months after the first day thereof. Any overdue
principal of or interest on any Money Market Loan shall bear interest, payable
on demand, for each day until paid at a rate per annum equal to the sum of 2%
plus the Base Rate for such day.



                                       26

<PAGE>   31


            (f) The Agent shall determine each interest rate applicable to the
Loans hereunder. The Agent shall give prompt notice to the Borrower and the
participating Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.

            (g) Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section 2.07. If any Reference
Bank does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available on
a timely basis, the provisions of Section 8.01 shall apply.

           SECTION 2.08. Facility Fee. The Borrower shall pay to the Agent for
the account of the Banks ratably in proportion to their Commitments a facility
fee at the Facility Fee Rate (determined daily in accordance with the Pricing
Schedule). Such facility fee shall accrue (i) from and including the Effective
Date to but excluding the Termination Date (or earlier date of termination of
the Commitments in their entirety), on the daily aggregate amount of the
Commitments (whether used or unused) and (ii) from and including the Termination
Date or such earlier date of termination to but excluding the date the Loans
shall be repaid in their entirety, on the daily aggregate outstanding principal
amount of the Loans. Accrued fees under this Section shall be payable quarterly
in arrears on each Quarterly Payment Date and upon the date of termination of
the Commitments in their entirety (and, if later, the date the Loans shall be
repaid in their entirety).

           SECTION 2.09. Optional Termination or Reduction of Commitments. The
Borrower may, upon at least three Domestic Business Days' notice to the Agent,
(i) terminate the Commitments at any time, if no Loans are outstanding at such
time or (ii) ratably reduce from time to time by an aggregate amount of
$10,000,000 or any larger multiple thereof, the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans.

           SECTION 2.10. Scheduled Termination of Commitments. The Commitments
shall terminate on the Termination Date, and any Loans then outstanding
(together with accrued interest thereon) shall be due and payable on such date.

           SECTION 2.11. Optional Prepayments. (a) The Borrower may (i) upon at
least one Domestic Business Day's notice to the Agent, prepay any Base Rate
Borrowing (or any Money Market Borrowing bearing interest at the Base Rate
pursuant to Section 8.01(a)), (ii) upon at least three Domestic Business Days'



                                       27

<PAGE>   32


notice to the Agent, subject to Section 2.13, prepay any CD Borrowing and (iii)
upon at least three Euro-Dollar Business Days' notice to the Agent, subject to
Section 2.13, prepay any Euro-Dollar Borrowing, in whole at any time, or from
time to time in part in amounts aggregating $15,000,000 or any larger multiple
of $1,000,000, by paying the principal amount to be prepaid together with
accrued interest thereon to the date of prepayment. Each such optional
prepayment shall be applied to prepay ratably the Loans of the several Banks
included in such Borrowing.

            (b) Except as provided in Section 2.11(a), the Borrower may not
prepay all or any portion of the principal amount of any Money Market Loan prior
to the maturity thereof.

            (c) Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share (if any) of such prepayment and such notice shall not
thereafter be revocable by the Borrower.

           SECTION 2.12. General Provisions as to Payments. (a) The Borrower
shall make each payment of principal of, and interest on, the Loans and of fees
hereunder, not later than 12:00 Noon (New York City time) on the date when due,
in Federal or other funds immediately available in New York City, to the Agent
at its address referred to in Section 9.01. The Agent will promptly distribute
to each Bank its ratable share of each such payment received by the Agent for
the account of the Banks. Whenever any payment of principal of, or interest on,
the Domestic Loans or of fees shall be due on a day which is not a Domestic
Business Day, the date for payment thereof shall be extended to the next
succeeding Domestic Business Day. Whenever any payment of principal of, or
interest on, the Euro-Dollar Loans shall be due on a day which is not a
Euro-Dollar Business Day, the date for payment thereof shall be extended to the
next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day
falls in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Dollar Business Day. Whenever any payment of
principal of, or interest on, the Money Market Loans shall be due on a day which
is not a Euro-Dollar Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Dollar Business Day. If the date for any
payment of principal is extended by operation of law or otherwise, interest
thereon shall be payable for such extended time.

            (b) Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Banks hereunder that the
Borrower will not make such payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent
may, in



                                       28

<PAGE>   33


reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the
Agent forthwith on demand such amount distributed to such Bank together with
interest thereon, for each day from the date such amount is distributed to such
Bank until the date such Bank repays such amount to the Agent, at the Federal
Funds Rate.

           SECTION 2.13. Funding Losses. If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan or any Fixed Rate Loan is
converted to a different type of Loan (whether such payment or conversion is
pursuant to Article 2, 6 or 8 or otherwise) on any day other than the last day
of an Interest Period applicable thereto, or the last day of an applicable
period fixed pursuant to Section 2.07(d), or if the Borrower fails to borrow,
prepay, convert or continue any Fixed Rate Loan after notice has been given to
any Bank in accordance with Section 2.04(a), 2.11(c) or 2.16(c), the Borrower
shall reimburse each Bank within 15 days after demand for any resulting loss or
expense incurred by it (or by an existing or prospective Participant in the
related Loan), including (without limitation) any loss incurred in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after such payment or conversion or failure to borrow,
prepay, convert or continue; provided that such Bank shall have delivered to the
Borrower a certificate as to the amount of such loss or expense, setting forth
the basis of calculation thereof, which certificate shall be conclusive in the
absence of manifest error.

           SECTION 2.14. Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
facility fees shall be computed on the basis of a year of 360 days and paid for
the actual number of days elapsed (including the first day but excluding the
last day).

           SECTION 2.15. Regulation D Compensation. For so long as any Bank
maintains reserves against "EUROCURRENCY LIABILITIES" (or any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of such Bank to United
States residents), and as a result the cost to such Bank (or its Euro-Dollar
Lending Office) of making or maintaining its Euro-Dollar Loans is increased,
then such Bank may require the Borrower to pay, contemporaneously (or at such
other time or times as the Borrower and such Bank may mutually agree) with each
payment of interest on the Euro-Dollar Loans, additional interest on the related
Euro-Dollar Loan of such Bank at a rate per annum up to but not exceeding the
excess of (i)



                                       29
<PAGE>   34


(A) the applicable London Interbank Offered Rate divided by (B) one minus the
Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered
Rate. Any Bank wishing to require payment of such additional interest (x) shall
so notify the Borrower and the Agent, in which case such additional interest on
the Euro-Dollar Loans of such Bank shall be payable to such Bank at the place
indicated in such notice with respect to each Interest Period commencing at
least three Euro-Dollar Business Days after the giving of such notice and (y)
shall furnish to the Borrower at least five Euro-Dollar Business Days prior to
each date on which interest is payable on the Euro-Dollar Loans (or at such
other time or times as the Borrower and such Bank may mutually agree) an
officer's certificate setting forth the amount to which such Bank is then
entitled under this Section 2.15 (which shall be consistent with such Bank's
good faith estimate of the level at which the related reserves are maintained by
it). Each such certificate shall be accompanied by such information as the
Borrower may reasonably request as to the computation set forth therein.

           SECTION 2.16. Method of Electing Interest Rates. (a) The Loans
included in each Committed Borrowing shall bear interest initially at the type
of rate specified by the Borrower in the applicable Notice of Committed
Borrowing. Thereafter, the Borrower may from time to time elect to change or
continue the type of interest rate borne by each Group of Loans (subject to
Section 2.16(d) and the provisions of Article 8), as follows:

                (i) if such Loans are Base Rate Loans, the Borrower may elect to
        convert such Loans to CD Loans as of any Domestic Business Day or to
        Euro-Dollar Loans as of any Euro-Dollar Business Day;

                (ii) if such Loans are CD Loans, the Borrower may elect to
        convert such Loans to Base Rate Loans as of any Domestic Business Day or
        convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business
        Day or continue such Loans as CD Loans for an additional Interest
        Period, subject to Section 2.13 if any such conversion is effective on
        any day other than the last day of an Interest Period applicable to such
        Loans; and

                (iii) if such Loans are Euro-Dollar Loans, the Borrower may
        elect to convert such Loans to Base Rate Loans as of any Domestic
        Business Day or convert such Loans to CD Loans as of any Euro-Dollar
        Business Day or elect to continue such Loans as Euro-Dollar Loans for an
        additional Interest Period, subject to Section 2.13 if any such
        conversion is effective on any day other than the last day of an
        Interest Period applicable to such Loans.

           Each such election shall be made by delivering a notice (a "NOTICE OF
           INTEREST RATE ELECTION") to the Agent not later than 10:30 A.M. (New
           York City time) on the third Euro-Dollar Business Day before the
           conversion or continuation selected in such notice is to be effective
           (unless the relevant Loans are to be converted from Domestic Loans of
           one type to Domestic Loans of the other type or are CD Loans to be
           continued as CD Loans for an additional Interest Period, in which
           case such notice shall be delivered to the Agent not later than 10:30
           A.M. (New York City time) on the second Domestic Business Day before
           such conversion or continuation is to be effective). A Notice of
           Interest Rate Election may, if it so specifies, apply to only a
           portion of the aggregate principal amount of the relevant Group of
           Loans; provided that (i) such portion is allocated ratably among the
           Loans comprising such Group and (ii) the portion to which such Notice
           applies, and the remaining portion to which it does not apply, are
           each at least $15,000,000 (unless such portion is comprised of Base
           Rate Loans). If no such notice is timely received before the end of
           an Interest Period for any Group of CD Loans or Euro-Dollar Loans,
           the Borrower shall be deemed to have elected that such Group of Loans
           be converted to Base Rate Loans at the end of such Interest Period.

            (b)   Each Notice of Interest Rate Election shall specify:

                        (i) the Group of Loans (or portion thereof) to which
            such notice applies;

                        (ii) the date on which the conversion or continuation
            selected in such notice is to be effective, which shall comply with
            the applicable clause of Section 2.16(a) above;

                        (iii) if the Loans comprising such Group are to be
            converted, the new type of Loans and, if the Loans resulting from
            such conversion are to be CD Loans or Euro-Dollar Loans, the
            duration of the next succeeding Interest Period applicable thereto;
            and

                        (iv) if such Loans are to be continued as CD Loans or
            Euro-Dollar Loans for an additional Interest Period, the duration of
            such additional Interest Period.

            Each Interest Period specified in a Notice of Interest Rate Election
            shall comply with the provisions of the definition of Interest
            Period.

            (c) Promptly after receiving a Notice of Interest Rate Election from
the Borrower pursuant to Section 2.16(a) above, the Agent shall notify each Bank
of



                                       31

<PAGE>   36


the contents thereof and such notice shall not thereafter be revocable by the
Borrower.

            (d) The Borrower shall not be entitled to elect to convert any
Committed Loans to, or continue any Committed Loans for an additional Interest
Period as, CD Loans or Euro-Dollar Loans if (i) the aggregate principal amount
of any Group of CD Loans or Euro-Dollar Loans created or continued as a result
of such election would be less than $15,000,000 or (ii) a Default shall have
occurred and be continuing when the Borrower delivers notice of such election to
the Agent.

            (e) If any Committed Loan is converted to a different type of Loan,
the Borrower shall pay, on the date of such conversion, the interest accrued to
such date on the principal amount being converted.

            aggregate outstanding principal amount of the Loans will not exceed
            the aggregate amount of the Commitments;

                        (c) the fact that, immediately before and after such

            the Borrower contained in this Agreement shall be true on and as of

                         REPRESENTATIVES AND WARRANTIES

           The Borrower represents and warrants that:

Agreement and the Notes are within the Borrower's corporate powers, have been
duly authorized by all necessary corporate action, require no action by or in

           SECTION 4.03. Binding Effect. This Agreement constitutes a valid and
binding agreement of the Borrower and each Note, when executed and delivered in
accordance with this Agreement, will constitute a valid and binding obligation
of the Borrower, in each case enforceable in accordance with its terms.

           SECTION 4.04. Financial Information. (a) The consolidated balance
sheets of the Borrower and its Consolidated Subsidiaries as of July 31, 1996 and
1997 and the related consolidated statements of operations, shareholders'
investment and cash flows for each of the three years ended July 31, 1997,
reported on by Deloitte & Touche and set forth in the Borrower's 1997 Form 10-K,
a copy of which has been delivered to each of the Banks, fairly present, in
conformity with generally accepted accounting principles, the consolidated
financial position of the Borrower and its Consolidated Subsidiaries as of such
dates and their consolidated results of operations and cash flows for such
fiscal years.

            (b) The consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries as of January 31, 1998 and the related consolidated
statements of operations and cash flows for the six months then ended, set forth

Section, the consolidated financial position of the Borrower and its

adjustments).

            (c) Since January 31, 1998 there has been no material adverse change
in the business, financial position, results of operations or prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.



                                       34

           SECTION 4.05. Litigation. (a) Except for actions, suits or
proceedings (i) described in the Borrower's 1997 Form 10-K or (ii) commenced
after the date of this Agreement and disclosed in writing to the Banks, there is
no action, suit or proceeding pending against, or to the knowledge of the
Borrower threatened against or affecting, the Borrower or any of its
Subsidiaries before any court or arbitrator or any governmental body, agency or
official an adverse decision in which might materially adversely affect the
business, consolidated financial position or consolidated results of operations
of the Borrower and its Consolidated Subsidiaries taken as a whole.

            (b) Since the date of the Borrower's 1997 Form 10-K, there has been
no change in the status of the actions, suits and proceedings described therein
which materially and adversely affects the business, financial position, results

considered as a whole.

            (c) There is no action, suit or proceeding pending against, or to
the knowledge of the Borrower threatened against or affecting, the Borrower or
any of its Subsidiaries before any court or arbitrator or any governmental body,
agency or official which in any manner questions the validity of this Agreement
or the Notes.

           SECTION 4.06. Compliance with ERISA. Each member of the ERISA Group
has fulfilled its obligations under the minimum funding standards of ERISA and
the Internal Revenue Code with respect to each Plan and is in compliance in all
material respects with the presently applicable provisions of ERISA and the
Internal Revenue Code with respect to each Plan. No member of the ERISA Group
has (i) sought a waiver of the minimum funding standard under Section 412 of the
Internal Revenue Code in respect of any Plan, (ii) failed to make any
contribution or payment to any Plan or Multiemployer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could result in the imposition of a Lien or the posting of
a bond or other security under ERISA or the Internal Revenue Code or (iii)
incurred any liability under Title IV of ERISA other than a liability to the
PBGC for premiums under Section 4007 of ERISA.

           SECTION 4.07.  Environmental Matters.  In the ordinary course of its
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Subsidiaries, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain



                                       35

<PAGE>   40

compliance with environmental protection standards imposed by law or as a
condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Substances, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses). On the
basis of this review, and based upon conditions of which the Borrower has
knowledge and upon its estimates of the costs of compliance with and/or
remediation mandated by Environmental Laws, the Borrower has reasonably
concluded that Environmental Laws are unlikely to have a material adverse effect
on the business, financial condition, results of operations or prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.

           SECTION 4.08. Taxes. The Borrower and its Subsidiaries have filed all
United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by the Borrower or any
Subsidiary. In the Borrower's opinion, all material tax liabilities were
adequately provided for as of July 31, 1997 and are now so provided for in the
books of the Borrower and its Consolidated Subsidiaries.

           SECTION 4.09. Material Subsidiaries. Each of the Borrower's Material
Subsidiaries is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation, and has all
corporate powers and all material governmental licenses, authorizations,
consents and approvals required to carry on its business as now conducted.

           SECTION 4.10.  Not an Investment Company.  The Borrower is not an
"INVESTMENT COMPANY" within the meaning of the Investment Company Act of
1940, as amended.

           SECTION 4.11. Use of Proceeds. The proceeds of the loans under this
Agreement will be used for general corporate purposes. None of such proceeds
will be used, directly or indirectly, for the purpose, whether immediate,
incidental or ultimate, of buying or carrying any "MARGIN STOCK", within the
meaning of Regulation U.

           SECTION 4.12. Full Disclosure. All information heretofore furnished
by the Borrower to the Agent or any Bank for purposes of or in connection with
this Agreement or any transaction contemplated hereby is, and all such
information hereafter furnished by the Borrower to the Agent or any Bank will
be, true and accurate in all material respects on the date as of which such
information is stated



                                       36

or certified. The Borrower has disclosed to the Banks in writing any and all
facts which materially and adversely affect or may affect (to the extent the
Borrower can now reasonably foresee), the business, operations or financial
condition of the Borrower and its Consolidated Subsidiaries, taken as a whole,
or the ability of the Borrower to perform its obligations under this Agreement.



                                    ARTICLE 5
                                    COVENANTS

their respective properties in at least such amounts and against at least such
risks (and with such risk retention) as are usually insured against in the same

therewith is contested in good faith by appropriate proceedings.

           Bank;

                      (d) any representation, warranty, certification or
           statement made (or deemed made) by the Borrower in this Agreement or
           in any certificate, financial statement or other document delivered
           pursuant to this Agreement shall prove to have been incorrect in any

           official in an involuntary case or other proceeding commenced against
           it, or shall make a general assignment for the benefit of creditors,

           against the Borrower or any Material Subsidiary under the federal
           bankruptcy laws as now or hereafter in effect;

                      (i) any member of the ERISA Group shall fail to pay when
           due an amount or amounts aggregating in excess of $10,000,000 which
           it shall have become liable to pay under Title IV of ERISA; or notice

           from, or a default, within the meaning of Section 4219(c)(5) of
           ERISA, with respect to, one or more Multiemployer Plans which could
           cause one or more members of the ERISA Group to incur a current
           payment obligation in excess of $10,000,000;

                      (j) a judgment or order for the payment of money in excess
           of $10,000,000 shall be rendered against the Borrower or any Material
           Subsidiary and such judgment or order shall continue unsatisfied and
           unstayed for a period of 30 days; or

                      (k) a Change of Control shall occur;

then, and in every such event, the Agent shall (i) if requested by Banks having
more than 50% in aggregate amount of the Commitments, by notice to the Borrower
terminate the Commitments and they shall thereupon terminate, and (ii) if
requested by Banks holding more than 50% in aggregate principal amount of the
Loans, by notice to the Borrower declare the Loans (together with accrued
interest thereon) to be, and the Loans (together with accrued interest thereon)
shall thereupon become, immediately due and payable without presentment, demand,

Borrower; provided that in the case of any of the Events of Default specified in
clause (g) or (h) above with respect to the Borrower, without any notice to the
Borrower or any other act by the Agent or any Bank, the Commitments shall
thereupon terminate and the Loans (together with accrued interest thereon) shall
become immediately due and payable without presentment, demand, protest or other
notice of any kind, all of which are hereby waived by the Borrower.

appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under this Agreement and the Notes as are delegated to
the Agent by the terms hereof or thereof, together with all such powers as are
reasonably incidental thereto.

           SECTION 7.02. Agent and Affiliates. Morgan Guaranty Trust Company of
New York shall have the same rights and powers under this Agreement as any other

the Agent, and Morgan Guaranty Trust Company of New York and its affiliates may
accept deposits from, lend money to, and generally engage in any kind of
business with the Borrower or any Subsidiary or Affiliate of the Borrower as if
it were not the Agent hereunder.

           SECTION 7.03. Action by Agent. The obligations of the Agent hereunder
are only those expressly set forth herein. Without limiting the generality of
the foregoing, the Agent shall not be required to take any action with respect
to any Default, except as expressly provided in Article 4.

           SECTION 7.04.  Consultation with Experts.  The Agent may consult with
legal counsel (who may be counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

           SECTION 7.05. Liability of Agent. Neither the Agent nor any of its
affiliates nor any of the directors, officers, agents or employees of the
foregoing shall be liable for any action taken or not taken by it or them in
connection herewith (i) with the consent or at the request of the Required Banks
or (ii) in the absence of its or their own gross negligence or willful
misconduct. Neither the Agent nor any of its affiliates nor any of the
directors, officers, agents or employees of the foregoing shall be responsible
for or have any duty to ascertain, inquire into or verify (i) any statement,
warranty or representation made in connection with this Agreement or any
borrowing hereunder; (ii) the performance

satisfaction of any condition specified in Article 3, except receipt of items
required to be delivered to the Agent; or (iv) the validity, effectiveness or
genuineness of this Agreement, the Notes or any other instrument or writing
furnished in connection herewith. The Agent shall not incur any liability by
acting in reliance upon any notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex or similar writing) believed by it to
be genuine or to be signed by the proper party or parties.

           SECTION 7.06. Indemnification. Each Bank shall, ratably in accordance
with its Commitment, indemnify the Agent, its affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the
Borrower) against any cost, expense (including counsel fees and disbursements),
claim, demand, action, loss or liability (except such as result from such
indemnitees' gross negligence or willful misconduct) that such indemnitees may
suffer or incur in connection with this Agreement or any action taken or omitted
by such indemnitees hereunder.

           SECTION 7.07. Credit Decision. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based

appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

           SECTION 7.08.  Successor Agent.  The Agent may resign at any time by
giving notice thereof to the Banks and the Borrower.  Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent, subject to
the approval of the Borrower. If no successor Agent shall have been so appointed
by the Required Banks, with the approval of the Borrower, and shall have
accepted such appointment, within 30 days after the retiring Agent gives notice
of resignation, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a Bank, if any Bank is willing to accept such
appointment, and in any event shall be a commercial bank organized or licensed
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $50,000,000. Upon the
acceptance of its appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the rights
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation hereunder as Agent,



                                       45

<PAGE>   50

the provisions of this Article shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent.

                                    ARTICLE 8
                             CHANGE IN CIRCUMSTANCES

           SECTION 8.01. Basis for Determining Interest Rate Inadequate or
Unfair. If on or prior to the first day of any Interest Period for any CD Loans,
Euro-Dollar Loans or Money Market LIBOR Loan:

                      (a) the Agent is advised by the Reference Banks that
           deposits in dollars (in the applicable amounts) are not being offered
           to the Reference Banks in the relevant market for such Interest
           Period, or

                      (b) in the case of CD Loans or Euro-Dollar Loans, Banks
           having 50% or more of the aggregate amount of the Commitments advise
           the Agent that the Adjusted CD Rate or the London Interbank Offered
           Rate, as the case may be, as determined by the Agent will not
           adequately and fairly reflect the cost to such Banks of funding their
           CD Loans or Euro-Dollar Loans, as the case may be, for such Interest
           Period,

the Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon until the Agent notifies the Borrower that the circumstances giving
rise to such suspension no longer exist, (i) the obligations of the Banks to
make CD Loans or Euro-Dollar Loans, as the case may be, or to continue or
convert outstanding Loans as or into CD Loans or Euro-Dollar Loans, as the case
may be, shall be suspended and (ii) each outstanding CD Loan or Euro-Dollar
Loan, as the case may be, shall be converted into a Base Rate Loan on the last
day of the then current Interest Period applicable thereto. Unless the Borrower
notifies the Agent at least two Domestic Business Days before the date of any
Fixed Rate Borrowing for which a Notice of Borrowing has previously been given
that it elects not to borrow on such date, (i) if such Fixed Rate Borrowing is a
Committed Borrowing, such Borrowing shall instead be made as a Base Rate
Borrowing and (ii) if such Fixed Rate Borrowing is a Money Market LIBOR
Borrowing, the Money Market LIBOR Loans comprising such Borrowing shall bear
interest for each day from and including the first day to but excluding the last
day of the Interest Period applicable thereto at the Base Rate for such day.



                                       46

<PAGE>   51

           SECTION 8.02. Illegality. If, on or after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Euro-Dollar Lending Office) with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency shall make it unlawful or impossible for any Bank (or its
Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and
such Bank shall so notify the Agent, the Agent shall forthwith give notice
thereof to the other Banks and the Borrower, whereupon until such Bank notifies
the Borrower and the Agent that the circumstances giving rise to such suspension
no longer exist, the obligation of such Bank to make Euro-Dollar Loans or to
convert outstanding Loans into Euro-Dollar Loans or continue outstanding Loans
as Euro-Dollar Loans, shall be suspended. Before giving any notice to the Agent
pursuant to this Section 8.02, such Bank shall designate a different Euro-Dollar
Lending Office if such designation will avoid the need for giving such notice
and will not, in the judgment of such Bank, be otherwise disadvantageous to such
Bank. If such notice is given, each Euro-Dollar Loan of such Bank then
outstanding shall be converted to a Base Rate Loan either (i) on the last day of
the then current Interest Period applicable to such Euro-Dollar Loan if such
Bank may lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan
to such day or (ii) immediately if such Bank shall determine that it may not
lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan to such
day. Interest and principal on any such Base Rate Loan shall be payable on the
same dates as, and on a pro rata basis with, the interest and principal payable
on the related Euro-Dollar Loans of the other Banks.

           SECTION 8.03. Increased Cost and Reduced Return. (a) If on or after
(x) the date hereof, in the case of any Committed Loan or any obligation to make
Committed Loans or (y) the date of the related Money Market Quote, in the case
of any Money Market Loan, the adoption of any applicable law, rule or
regulation, or any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Applicable Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency shall
impose, modify or deem applicable any reserve (including, without limitation,
any such requirement imposed by the Board of Governors of the Federal Reserve
System, but excluding



                                       47

<PAGE>   52

(i) with respect to any CD Loan any such requirement included in an applicable
Domestic Reserve Percentage and (ii) with respect to any Euro-Dollar Loan any
such requirement with respect to which such Bank is entitled to compensation
during the relevant Interest Period under Section 2.15), special deposit,
insurance assessment (excluding, with respect to any CD Loan, any such
requirement reflected in an applicable Assessment Rate) or similar requirement
against assets of, deposits with or for the account of, or credit extended by,
any Bank (or its Applicable Lending Office) or shall impose on any Bank (or its
Applicable Lending Office) or on the United States market for certificates of
deposit or the London interbank market any other condition affecting its Fixed
Rate Loans, its Note or its obligation to make Fixed Rate Loans and the result
of any of the foregoing is to increase the cost to such Bank (or its Applicable
Lending Office) of making or maintaining any Fixed Rate Loan, or to reduce the
amount of any sum received or receivable by such Bank (or its Applicable Lending
Office) under this Agreement or under its Note with respect thereto, by an
amount deemed by such Bank to be material, then, within 15 days after demand by
such Bank (with a copy to the Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank for such increased
cost or reduction.

            (b) If any Bank shall have determined that, after the date hereof,
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency (including any determination by any such authority, central
bank or comparable agency that, for purposes of capital adequacy requirements,
the Commitments hereunder do not constitute commitments with an original
maturity of one year or less), has or would have the effect of reducing the rate
of return on capital of such Bank (or its Parent) as a consequence of such
Bank's obligations hereunder to a level below that which such Bank (or its
Parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, within 15
days after demand by such Bank (with a copy to the Agent), the Borrower shall
pay to such Bank such additional amount or amounts as will compensate such Bank
(or its Parent) for such reduction; provided that the Borrower shall not be
liable for any such amounts attributable to a period more than three months
prior to the date of notice by such Bank to the Borrower of its intention to
seek compensation under this subsection (b).

            (c) Each Bank will promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle



                                       48

such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank
claiming compensation under this Section, setting forth the additional amount or
amounts to be paid to it hereunder and the basis of calculation thereof, shall
be conclusive in the absence of manifest error. In determining such amount, such
Bank may use any reasonable averaging and attribution methods.

           SECTION 8.04. Taxes. (a) Any and all payments by the Borrower to or
for the account of any Bank or the Agent hereunder or under any Note shall be
made free and clear of and without deduction for any and all present or future
taxes, duties, levies, imposts, deductions, charges and withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank and the
Agent, taxes imposed on its income, and franchise taxes imposed on it, by the
jurisdiction under the laws of which such Bank or the Agent (as the case may be)
is organized or any political subdivision thereof and, in the case of each Bank,
taxes imposed on its income, and franchise or similar taxes imposed on it, by
the jurisdiction of such Bank's Applicable Lending Office or any political
subdivision thereof (all such non-excluded taxes, duties, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "TAXES"). If the Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any Note to any Bank or the
Agent, (i) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 8.04) such Bank or the Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Agent, at its address referred to in Section 9.01, the original
or a certified copy of a receipt evidencing payment thereof.

            (b) In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made hereunder or under any Note or
from the execution or delivery of, or otherwise with respect to, this Agreement
or any Note (hereinafter referred to as "OTHER TAXES").

            (c) The Borrower agrees to indemnify each Bank and the Agent for the
full amount of Taxes and Other Taxes (including, without limitation, any Taxes
and Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section 8.04) paid by such Bank or the Agent (as the case may be) and



                                       49

<PAGE>   54

any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto. This indemnification shall be made within 15 days from the
date such Bank or the Agent (as the case may be) makes demand therefor.

            (d) Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
and from time to time thereafter if requested in writing by the Borrower (but
only so long as such Bank remains lawfully able to do so), shall provide the
Borrower with Internal Revenue Service form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Bank is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States. If the form provided by a Bank at the time such Bank first becomes a
party to this Agreement indicates a United States interest withholding tax rate
in excess of zero, withholding tax at such rate shall be considered excluded
from "TAXES" as defined in Section 8.04(a).

            (e) For any period with respect to which a Bank has failed to
provide the Borrower with the form required pursuant to Section 8.04(d), if any
(unless such failure is due to a change in treaty, law or regulation occurring
subsequent to the date on which a form originally was required to be provided),
such Bank shall not be entitled to indemnification under Section 8.04(a) with
respect to Taxes imposed by the United States; provided, however, that should a
Bank, which is otherwise exempt from or subject to a reduced rate of withholding
tax, become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Bank shall reasonably
request to assist such Bank to recover such Taxes.

            (f) If the Borrower is required to pay additional amounts to or for
the account of any Bank pursuant to this Section 8.04, then such Bank will
change the jurisdiction of its Applicable Lending Office so as to eliminate or
reduce any such additional payment which may thereafter accrue if such change,
in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

           SECTION 8.05. Base Rate Loans Substituted for Affected Fixed Rate
Loans. If (i) the obligation of any Bank to make, or to continue or convert
outstanding Loans as or to, Euro-Dollar Loans has been suspended pursuant to
Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03 or
8.04 with respect to its CD Loans or Euro-Dollar Loans, and in any such case the



                                       50

<PAGE>   55

Borrower shall, by at least five Euro-Dollar Business Days' prior notice to such
Bank through the Agent, have elected that the provisions of this Section shall
apply to such Bank, then, unless and until such Bank notifies the Borrower that
the circumstances giving rise to such suspension or demand for compensation no
longer exist, all Loans which would otherwise be made by such Bank as (or
continued as or converted to) CD Loans or Euro-Dollar Loans, as the case may be,
shall instead be Base Rate Loans on which interest and principal shall be
payable contemporaneously with the related CD Loans or Euro-Dollar Loans of the
other Banks. If such Bank notifies the Borrower that the circumstances giving
rise to such suspension or demand for compensation no longer exist, the
principal amount of each such Base Rate Loan shall be converted into a CD Loan
or Euro-Dollar Loan, as the case may be, on the first day of the next
succeeding Interest Period applicable to the related CD Loans or Euro-Dollar
Loans of the other Banks.

           SECTION 8.06. Substitution of Bank. If (i) the obligation of any Bank
to make Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii)
any Bank has demanded compensation under Section 8.03 or 8.04, the Borrower
shall have the right, with the assistance of the Agent, to seek a mutually
satisfactory substitute bank or banks (which may be one or more of the Banks) to
purchase the Loans and assume the Commitment of such Bank.

                                    ARTICLE 9
                                  MISCELLANEOUS

           SECTION 9.01. Notices. All notices, requests and other communications
to any party hereunder shall be in writing (including bank wire, telex,
facsimile transmission or similar writing) and shall be given to such party: (x)
in the case of the Borrower or the Agent, at its address or facsimile or telex
number set forth on the signature pages hereof, (y) in the case of any Bank, at
its address or facsimile or telex number set forth in its Administrative
Questionnaire or (z) in the case of any party, such other address or facsimile
or telex number as such party may hereafter specify for the purpose by notice to
the Agent and the Borrower. Each such notice, request or other communication
shall be effective (i) if given by telex, when such telex is transmitted to the
telex number specified in this Section and the appropriate answerback is
received, (ii) if given by mail, 72 hours after such communication is deposited
in the mails with first class postage prepaid, addressed as aforesaid or (iii)
if given by any other means, when delivered at the address specified in this
Section; provided that notices to the Agent under Article 2 or Article 8 shall
not be effective until received.



                                       51

<PAGE>   56

           SECTION 9.02. No Waivers. No failure or delay by the Agent or any
Bank in exercising any right, power or privilege hereunder or under any Note
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies herein provided shall
be cumulative and not exclusive of any rights or remedies provided by law.

           SECTION 9.03. Expenses; Indemnification. (a) The Borrower shall pay
(i) all out-of-pocket expenses of the Agent, including fees and disbursements of
special counsel for the Agent, in connection with the preparation and
administration of this Agreement, any waiver or consent hereunder or any
amendment hereof or any Default or alleged Default hereunder and (ii) if an
Event of Default occurs, all out-of-pocket expenses incurred by the Agent or any
Bank, including fees and disbursements of outside counsel (or, in lieu thereof,
the allocated cost of in-house counsel), in connection with such Event of
Default and collection, bankruptcy, insolvency and other enforcement proceedings
resulting therefrom.

            (b) The Borrower agrees to indemnify the Agent and each Bank, their
respective affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "INDEMNITEE") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be incurred by such Indemnitee in connection
with any investigative, administrative or judicial proceeding (whether or not
such Indemnitee shall be designated a party thereto) brought or threatened
relating to or arising out of this Agreement or any actual or proposed use of
proceeds of Loans hereunder; provided that no Indemnitee shall have the right to
be indemnified hereunder for such Indemnitee's own gross negligence or willful
misconduct.

           SECTION 9.04. Sharing of Set-Offs. Each Bank agrees that if it shall,
by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate amount of principal and interest due with
respect to the Loans held by it which is greater than the proportion received by
any other Bank in respect of the aggregate amount of principal and interest due
with respect to the Loans held by such other Bank, the Bank receiving such
proportionately greater payment shall purchase such participations in the Loans
held by the other Banks, and such other adjustments shall be made, as may be
required so that all such payments of principal and interest with respect to the
Loans held by the Banks shall be shared by the Banks pro rata; provided that
nothing in this Section shall impair the right of any Bank to exercise any right
of set-off or counterclaim it may have and to apply the amount subject to such
exercise to the payment of indebtedness of the Borrower other than its
indebtedness under this Agreement.



                                       52

<PAGE>   57

The Borrower agrees, to the fullest extent it may effectively do so under
applicable law, that any holder of a participation in a Loan, whether or not
acquired pursuant to the foregoing arrangements, may exercise rights of set-off
or counterclaim and other rights with respect to such participation as fully as
if such holder of a participation were a direct creditor of the Borrower in the
amount of such participation.

           SECTION 9.05. Amendments and Waivers. Any provision of this Agreement
or the Notes may be amended or waived if, but only if, such amendment or waiver
is in writing and is signed by the Borrower and the Required Banks (and, if the
rights or duties of the Agent are affected thereby, by the Agent); provided that
no such amendment or waiver shall:

                      (a) unless signed by all the Banks, (i) increase or
           decrease the Commitment of any Bank (except for a ratable decrease in
           the Commitments of all the Banks) or subject any Bank to any
           additional obligation, (ii) reduce the principal of or rate of
           interest on any Loan or any fees hereunder, (iii) postpone the date
           fixed for any payment of principal of or interest on any Loan or any
           fees hereunder or for the termination of any Commitment or (iv)
           change the percentage of the Commitments or of the aggregate unpaid
           principal amount of the Loans, or the number of Banks, which shall be
           required for the Banks or any of them to take any action under this
           Section or any other provision of this Agreement; or

                      (b) unless signed by a Designated Lender or its
           Designating Bank, subject such Designated Lender to any additional
           obligation or affect its rights hereunder (unless the rights of all
           the Banks hereunder are similarly affected).

           SECTION 9.06. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

            (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "PARTICIPANT") participating interests in its Commitment or
in any or all of its Loans. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations



                                       53

<PAGE>   58

under this Agreement. Any agreement pursuant to which any Bank may grant such a
participating interest shall provide that such Bank shall retain the sole right
and responsibility to enforce the obligations of the Borrower hereunder
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such participation
agreement may provide that such Bank will not agree to any modification,
amendment or waiver of this Agreement described in clause (i), (ii) or (iii) of
Section 9.05 without the consent of the Participant. The Borrower agrees that
each Participant shall, to the extent provided in its participation agreement,
be entitled to the benefits of Section 2.15 and Article 8 with respect to its
participating interest. An assignment or other transfer which is not permitted
by subsection (c) or (d) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this subsection (b).

            (c) Any Bank may at any time assign to one or more banks or other
institutions (each an "ASSIGNEE") all, or a proportionate part (equivalent to a
Commitment of not less than $5,000,000) of all, of its rights and obligations
under this Agreement and the Notes (if any), and such Assignee shall assume such
rights and obligations, pursuant to an Assignment and Assumption Agreement in
substantially the form of Exhibit G hereto executed by such Assignee and such
transferor Bank, with (and subject to) the subscribed consent of the Borrower
and the Agent (which consents shall not be unreasonably withheld); provided that
if an Assignee is a Bank or an affiliate of such transferor Bank, no such
consents shall be required; provided further that such assignment may, but need
not, include rights of the transferor Bank in respect of outstanding Money
Market Loans. Upon execution and delivery of such instrument and payment by such
Assignee to such transferor Bank of an amount equal to the purchase price agreed
between such transferor Bank and such Assignee, such Assignee shall be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank
with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required. Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Bank, the Agent and the Borrower shall make appropriate
arrangements so that, if required, a new Note is issued to the Assignee. In
connection with any such assignment, the transferor Bank shall pay to the Agent
an administrative fee for processing such assignment in the amount of $3,000. If
the Assignee is not incorporated under the laws of the United States of America
or a state thereof, it shall deliver to the Borrower and the Agent certification
as to exemption from deduction or withholding of any United States federal
income taxes in accordance with Section 8.04.



                                       54

<PAGE>   59

            (d) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note (if any) to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

            (e) No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under Section 8.03 or
8.04 than such Bank would have been entitled to receive with respect to the
rights transferred, unless such transfer is made with the Borrower's prior
written consent or by reason of the provisions of Section 8.02, 8.03 or 8.04
requiring such Bank to designate a different Applicable Lending Office under
certain circumstances.

           SECTION 9.07. Designated Lenders. (a) Subject to the provisions of
this Section 9.07(a), any Bank may from time to time elect to designate an
Eligible Designee to provide all or a portion of the Loans to be made by such
Bank pursuant to this Agreement; provided that such designation shall not be
effective unless the Borrower and the Agent consent thereto. When a Bank and its
Eligible Designee shall have signed an agreement substantially in the form of
Exhibit H hereto (a "DESIGNATION AGREEMENT") and the Borrower and the Agent
shall have signed their respective consents thereto, such Eligible Designee
shall become a Designated Lender for purposes of this Agreement. The Designating
Bank shall thereafter have the right to permit such Designated Lender to provide
all or a portion of the Loans to be made by such Designating Bank pursuant to
Section 2.01 or 2.03, and the making of such Loans or portions thereof shall
satisfy the obligation of the Designating Bank to the same extent, and as if,
such Loans or portion thereof were made by the Designating Bank. As to any Loans
or portion thereof made by it, each Designated Lender shall have all the rights
that a Bank making such Loans or portion thereof would have had under this
Agreement and otherwise; provided that (x) its voting rights under this
Agreement shall be exercised solely by Designating Bank and (y) its Designating
Bank shall remain solely responsible to the other parties hereto for the
performance of its obligations under this Agreement, including its obligations
in respect of the Loans or portion thereof made by it. No additional Note shall
be required to evidence Loans or portions thereof made by a Designated Lender;
and the Designating Bank shall be deemed to hold its Note (if any) as agent for
its Designated Lender to the extent of the Loans or portion thereof funded by
such Designated Lender. Each Designating Bank shall act as administrative agent
for its Designated Lender and give and receive notices and other communications
on its behalf. Any payments for the account of any Designated Lender shall be
paid to its Designating Bank as administrative agent for such Designated Lender
and neither the Borrower nor the Agent shall be responsible for any Designating
Bank's application of such payments. In addition, any Designated Lender may (i)
with notice to, but without the prior written consent of the Borrower or the
Agent, assign all or portions of its interest in any Loans to its Designating
Bank or to any financial institutions



                                       55

<PAGE>   60

consented to by the Borrower and the Agent providing liquidity and/or credit
facilities to or for the account of such Designated Lender to support the
funding of Loans or portions thereof made by such Designated Lender and (ii)
disclose on a confidential basis any non-public information relating to its
Loans or portions thereof to any rating agency, commercial paper dealer or
provider of any guarantee, surety, credit or liquidity enhancement to such
Designated Lender.

            (b) Each party to this Agreement agrees that it will not institute
against, or join any other person in instituting against, any Designated Lender
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding or other proceeding under any federal or state bankruptcy or similar
law, for one year and a day after all outstanding senior indebtedness of such
Designated Lender is paid in full. The Designating Bank for each Designated
Lender agrees to indemnify, save, and hold harmless each other party hereto for
any loss, cost, damage and expense arising out of its inability to institute any
such proceeding against such Designated Lender. This Section 9.07(b) shall
survive the termination of this Agreement.

           SECTION 9.08. Collateral. Each of the Banks represents to the Agent
and each of the other Banks that it in good faith is not relying upon any
"MARGIN STOCK" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

           SECTION 9.09. Governing Law; Submission to Jurisdiction. This
Agreement and each Note shall be governed by and construed in accordance with
the laws of the State of New York. The Borrower hereby submits to the
nonexclusive jurisdiction of the United States District Court for the Southern
District of New York and of any New York State court sitting in New York City
for purposes of all legal proceedings arising out of or relating to this
Agreement, the Notes or the transactions contemplated hereby. The Borrower
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient forum.

           SECTION 9.10. Counterparts; Integration. This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement constitutes the entire agreement and understanding among the
parties hereto and supersedes any and all prior agreements and understandings,
oral or written, relating to the subject matter hereof.



                                       56

           SECTION 9.11. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENT
AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE NOTES OR
THE TRANSACTIONS CONTEMPLATED HEREBY.

be duly executed by their respective authorized officers as of the day and year
first above written.

           For purposes of this Schedule, the following terms have the following
meanings:

           "D&P" means Duff & Phelps Credit Rating Co., and its successors.

           "LEVEL I STATUS" exists at any date if, at such date, the Borrower's
long-term debt is rated A-/A3 or higher by at least two Rating Agencies.

           "LEVEL II STATUS" exists at any date if, at such date, (i) the
Borrower's long-term debt is rated BBB+/Baa1 or higher by at least two Rating
Agencies and (ii) Level I Status does not exist at such date.

           "LEVEL III STATUS" exists at any date if, at such date, (i) the
Borrower's long-term debt is rated BBB/Baa2 or higher by at least two Rating
Agencies and (ii) neither Level I Status nor Level II Status exists at such
date.

           "LEVEL IV STATUS" exists at any date if, at such date, (i) the
Borrower's long-term debt is rated BBB-/Baa3 or higher by at least two Rating
Agencies and (ii) none of Level I Status, Level II Status or Level III Status
exists at such date.

           "LEVEL V STATUS" exists at any date, if at the close of business on
such date, none of Level I Status, Level II Status, Level III Status or Level IV
Status exists.

           "MOODY'S" means Moody's Investors Service, Inc., and its successors.

           "RATING AGENCIES" means D&P, Moody's and S&P.



<PAGE>   68

           "S&P" means Standard & Poor's Ratings Group, and its successors.

           "STATUS" refers to the determination of which of Level I Status,
Level II Status, Level III Status, Level IV Status or Level V Status exists at
any date.

           "UTILIZATION" means at any date the percentage equivalent of a
fraction (i) the numerator of which is the aggregate outstanding principal
amount of the Loans at such date, after giving effect to any borrowing or
payment on such date, and (ii) the denominator of which is the aggregate amount
of the Commitments at such date, after giving effect to any reduction of the
Commitments on such date. For purposes of this Schedule, if for any reason any
Loans remain outstanding after termination of the Commitments, the Utilization
for each date on or after the date of such termination shall be deemed to be
greater than 33%.

           The credit ratings to be utilized for purposes of determining a
Status hereunder are those assigned to the senior unsecured long-term debt of
the Borrower without third-party credit enhancement, and any rating assigned to
any other debt of the Borrower shall be disregarded; provided that if at any
time the Borrower's senior unsecured long-term debt is rated by exactly two
Rating Agencies and the ratings assigned to such debt by such two Rating
Agencies are more than one full rating category apart, Status shall be
determined based on a rating one category higher than the lower of such two
ratings (e.g., if the S&P rating is BBB+, the Moody's rating is Baa3 and there
is no D&P rating, then Level III Status shall exist); provided further that if
at any time the Borrower's senior unsecured long-term debt, without third party
credit enhancement, is not rated by at least two Rating Agencies, then Status
shall be level V Status. The rating in effect at any date is that in effect at
the close of business on such date.

                                   OPINION OF
                            COUNSEL FOR THE BORROWER

                                                      [Dated the Effective Date]

To the Banks and the Agent
  Referred to Below
c/o Morgan Guaranty Trust Company
  of New York, as Agent
60 Wall Street
New York, New York  10260-0060

Dear Sirs:

           I am the chief legal officer of Litton Industries, Inc. (the
"BORROWER") and have acted in that capacity in connection with the Credit
Agreement (the "CREDIT AGREEMENT") dated as of March 27, 1998 among the
Borrower, the banks listed on the signature pages thereof and Morgan Guaranty
Trust Company of New York, as Agent. Terms defined in the Credit Agreement are
used herein as therein defined.

           I have examined originals or copies, certified or otherwise
identified to my satisfaction, of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as I have deemed necessary or advisable for
purposes of this opinion.

           Upon the basis of the foregoing, I am of the opinion that:

             1. The Borrower is a corporation duly incorporated, validly
existing and in good standing under the laws of Delaware and has all corporate
powers and all material governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted.

             2. The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes are within the Borrower's corporate powers, have
been duly authorized by all necessary corporate action, require no action by or
in respect of, or filing with, any governmental body, agency or official and do
not contravene, or constitute a default under, any provision of applicable law
or regulation or of the certificate of incorporation or by-laws of the Borrower
or of any agreement, judgment, injunction, order, decree or other instrument
binding upon the Borrower or result in the creation or imposition of any Lien on
any asset of the Borrower or any of its Subsidiaries.



<PAGE>   77


             3. The Credit Agreement constitutes a valid and binding agreement
of the Borrower and each Note constitutes a valid and binding obligation of the
Borrower, in each case enforceable in accordance with its terms, except as the
same may be limited by bankruptcy, insolvency or similar laws affecting
creditors' rights generally and by general principles of equity.

             4. (a) Except for actions, suits or proceedings described in the
Borrower's 1997 Form 10-K, there is no action, suit or proceeding pending
against, or to the best of my knowledge threatened against or affecting, the
Borrower or any of its Subsidiaries before any court or arbitrator or any
governmental body, agency or official, in which there is a reasonable
possibility of an adverse decision which could materially adversely affect the
business, consolidated financial position or consolidated results of operations
of the Borrower and its Consolidated Subsidiaries, taken as a whole.

            (b) There is no action, suit or proceeding pending against, or to
the best of my knowledge threatened against or affecting, the Borrower or any of
its Subsidiaries before any court or arbitrator or any governmental body, agency
or official which in any manner questions the validity of the Credit Agreement
or the Notes.

             5. Each of the Borrower's Material Subsidiaries is a corporation
duly incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has all corporate powers and all material
governmental licenses, authorizations, consents and approvals required to carry
on its business as now conducted.

           I am a member of the Bar of the State of California, and the
foregoing opinion is limited to the laws of the State of California, the General
Corporation Law of the State of Delaware and the Federal laws of the United
States of America. Inasmuch as the Credit Agreement and the Notes are governed
by the law of the State of New York, I have assumed for purposes of the
foregoing opinion that such law is the same as the law of the State of
California.

                                                Very truly yours,

                     DAVIS POLK & WARDWELL, SPECIAL COUNSEL
                                  FOR THE AGENT

To the Banks and the Agent
  Referred to Below
c/o Morgan Guaranty Trust Company
  of New York, as Agent
60 Wall Street
New York, New York  10260-0060

Dear Sirs:

           We have participated in the preparation of the Credit Agreement (the
"CREDIT AGREEMENT") dated as of March 27, 1998 among Litton Industries, Inc., a
Delaware corporation (the "BORROWER"), the banks listed on the signature pages
thereof (the "BANKS") and Morgan Guaranty Trust Company of New York, as Agent
(the "AGENT"), and have acted as special counsel for the Agent for the purpose
of rendering this opinion pursuant to Section 3.01(c) of the Credit Agreement.
Terms defined in the Credit Agreement are used herein as therein defined.

           We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as we have deemed necessary or advisable
for purposes of this opinion.

           Upon the basis of the foregoing, we are of the opinion that:

             1. The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes are within the Borrower's corporate powers and
have been duly authorized by all necessary corporate action.

             2. The Credit Agreement constitutes a valid and binding agreement
of the Borrower and each Note constitutes a valid and binding obligation of the
Borrower, in each case enforceable in accordance with its terms, except as the
same may be limited by bankruptcy, insolvency or similar laws affecting
creditors' rights generally and by general principles of equity.



<PAGE>   79


             3. The documents delivered to the Agent by the Borrower pursuant to
Section 3.01 of the Credit Agreement are substantially responsive to the
requirements of said Section.

           We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York, the federal laws of the
United States of America and the General Corporation Law of the State of
Delaware. In giving the foregoing opinion, we express no opinion as to the
effect (if any) of any law of any jurisdiction (except the State of New York) in
which any Bank is located which limits the rate of interest that such Bank may
charge or collect.

           This opinion is rendered solely to you in connection with the above
matter. This opinion may not be relied upon by you for any other purpose or
relied upon by any other person without our prior written consent.


                                                    Very truly yours,

           WHEREAS, this Assignment and Assumption Agreement (the "AGREEMENT")
relates to the Credit Agreement dated as of March 27, 1998 among the Borrower,
the Assignor and the other Banks party thereto, as Banks, and the Agent (as
amended from time to time, the "CREDIT AGREEMENT");

           WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Committed Loans to the Borrower in an aggregate principal
amount at any time outstanding not to exceed $__________;

           WHEREAS, Committed Loans made to the Borrower by the Assignor under
the Credit Agreement in the aggregate principal amount of $__________ are
outstanding at the date hereof; and

           WHEREAS, the Assignor proposes to assign to the Assignee all of the

together with a corresponding portion of its outstanding Committed Loans, and
the Assignee proposes to accept assignment of such rights and assume the
corresponding obligations from the Assignor on such terms;

           NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

           SECTION 1.  Definitions.  All capitalized terms not otherwise defined

and delivery hereof by the Assignor, the Assignee, the Borrower and the Agent
and the payment of the amounts specified in Section 3 required to be paid on the
date hereof (i) the Assignee shall, as of the date hereof, succeed to the rights
and be obligated to perform the obligations of a Bank under the Credit Agreement
with a Commitment in an amount equal to the Assigned Amount, and (ii) the
Commitment of the Assignor shall, as of the date hereof, be reduced by a like
amount and the Assignor released from its obligations under the Credit Agreement
to the extent such obligations have been assumed by the Assignee. The assignment
provided for herein shall be without recourse to the Assignor.

           SECTION 3. Payments. As consideration for the assignment and sale
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds the amount heretofore agreed between them. It is
understood that commitment and/or facility fees accrued to the date hereof are
for the account of the Assignor and such fees accruing from and including the
date hereof in respect of the Assigned Amount are for the account of the
Assignee. Each of the Assignor and the Assignee hereby agrees that if it
receives any amount under the Credit Agreement which is for the account of the
other party hereto, it shall receive the same for the account of such other
party to the extent of such other party's interest therein and shall promptly
pay the same to such other party.

           SECTION 4. Consent of the Borrower and the Agent. This Agreement is
conditioned upon the consent of the Borrower and the Agent, pursuant to Section
9.06(c) of the Credit Agreement. The execution of this Agreement by the Borrower
and the Agent is evidence of this consent. Pursuant to Section 9.06(c) the
Borrower agrees to execute and deliver a Note payable to the order of the
Assignee to evidence the assignment and assumption provided for herein.]

           SECTION 5. Non-reliance on Assignor. The Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Borrower, or the validity and enforceability of the obligations of the Borrower
in respect of the Credit Agreement or any Note. The Assignee acknowledges that
it has, independently and without reliance on the Assignor, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and will continue to be
responsible for making its own independent appraisal of the business, affairs
and financial condition of the Borrower.

           SECTION 6.  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.



<PAGE>   82



           SECTION 7. Counterparts. This Agreement may be signed in any number
of counterparts, each of which shall be an original, with the same effect as if
