                                  THE COMPANY
 
OVERVIEW
 
  Danaher Corporation (the "Company" or "Danaher") designs, manufacturers and
markets industrial and consumer products with strong brand names, proprietary
technology and major market positions in two principal businesses:
Process/Environmental Controls and Tools and Components. The
Process/Environmental Controls segment is a leading producer of leak detection
systems for underground fuel storage tanks, compact professional electronic
test tools and motion, position, speed, temperature, pressure, level, flow,
particulate and power reliability and quality control and safety devices. In
its Tools and Components segment, Danaher is a leading producer and
distributor of general purpose mechanics' hand tools and automotive specialty
tools, as well as tool boxes and storage devices, diesel engine retarders,
wheel service equipment, drill chucks, custom designed headed tools and
components, hardware and components for the power generation and transmission
industries, precision socket screws, fasteners and miniature precision parts.
With the recent acquisitions of Pacific Scientific Company ("Pacific
Scientific") and Fluke Corporation ("Fluke"), on a pro forma basis for the
year ended 1997, the Process/Environmental Controls segment comprises
approximately 57.4% of 1997 net sales. See "Recent Developments." Danaher's
objective is to maintain its market leadership positions, while continuing to
improve financial performance through organic growth, international expansion
and selective acquisitions. The Company's principal executive offices are
located at 1240 24th Street, N.W., Suite 800, Washington, D.C. 20037. Its
telephone number is (202) 828-0850.
 
 
                                       2
<PAGE>
 
PROCESS/ENVIRONMENTAL CONTROLS
 
  The Process/Environmental Controls segment includes the Veeder-Root Company,
Danaher Controls, Partlow, Anderson Instruments, West Instruments, QualiTROL
Corporation, A.L. Hyde Company, Hengstler, American Sigma, the controls
product line business units of Joslyn Corporation, Namco Controls, Dolan-
Jenner, M&M Precision Systems, TxPort, Inc., Communications Technology
Corporation, Current Technology, Inc., Dr. Bruno Lange GmbH and Gems Sensors,
Inc. In addition, on March 9, 1998, Pacific Scientific's, and on July 9, 1998,
Fluke's businesses were added to this segment. See "Recent Developments." The
companies in this segment produce and sell underground storage tank leak
detection systems, compact professional electronic test tools, temperature,
level, speed, motion and position sensing devices, power switches and
controls, communication line products, power protection products, liquid flow
measuring and particulate measuring devices, telecommunication products,
aviation safety products, quality assurance products and systems and
electronic and mechanical counting and controlling devices. These products are
distributed by the Company's sales personnel and independent representatives
to original equipment manufacturers, distributors and other end users.
 
  Danaher's strategy in the Process/Environmental Controls segment is to
concentrate on the rapid expansion of its environmental controls product line,
including the Veeder-Root storage leak detection systems business. The Company
believes that Veeder-Root is the premier manufacturer of state-of-the-art tank
measuring and leak detection systems for underground fuel storage tanks, and,
accordingly, is uniquely positioned to respond to the demand for these
products fueled by environmental regulations.
 
  The Company is also expanding its other offerings in the environmental
controls product line to encompass applications related to markets other than
petroleum storage and to address nonregulatory business requirements. This
expansion program includes both internally developed new product offerings as
well as selective product line acquisitions.
 
  In its instruments and controls product line, Danaher's strategy is to
continue enhancing its global controls and instrument position by both new
product development and complimentary acquisitions. The companies within the
instrument group have significant synergies in both product offerings and
channels of distribution. Danaher's plan is to leverage these synergies in
product design, engineering and manufacturing and product marketing.
 
TOOLS AND COMPONENTS
 
  The Tools and Components segment is comprised of the Danaher Hand Tool Group
(including Special Markets, Professional Tools and Asian Tools divisions),
Matco Tools, Jacobs Chuck Manufacturing Company, Delta Consolidated
Industries, Jacobs Vehicle System, Hennessy Industries and the hardware and
electrical apparatus lines of Joslyn Manufacturing Company. This segment is
one of the largest domestic producers and distributors of general purpose and
specialty mechanics' hand tools. Other products manufactured by these
companies include tool boxes and storage devices, diesel engine retarders,
wheel service equipment, drill chucks, custom designed headed tools and
components, hardware and components for the power generation and transmission
industries, high quality precision socket screws, fasteners and high quality
miniature precision parts.
 
  In Tools and Components, the Company is the principal manufacturer of Sears,
Roebuck and Co.'s Craftsman(R) line, National Automotive Parts Association
(NAPA(R)) line, K-D(R) Automotive line and the Matco(R), Armstrong(R) and
Allen(TM) lines of mechanics' hand tools. The Company also manufactures
Allen(TM) wrenches, Jacobs(R) drill chucks and diesel engine retarders,
Delta(R) storage containers and Coats(R) and Ammco(R) wheel service equipment.
 
  The Company's business strategy in the Tools and Components segment is
focused on increasing sales to existing customers, broadening channels of
distribution, development of new products, geographic expansion and achieving
production efficiencies and enhanced quality and customer service through
"Just-In-Time" and related manufacturing techniques.

DANAHER BUSINESS SYSTEM
 
  The Company manages its two principal business segments with a management
philosophy which it calls "Danaher Business System." The Danaher Business
System is based on the following principles: (1) continuous improvement (a
concept known by the Japanese word "Kaizen"), (2) management process based on
Policy Deployment, (3) total associate involvement, (4) performance measured
by customer satisfaction and (5) enhanced profitability. The Danaher Business
System approach looks to the customer's satisfaction as a guideline for
continuous improvements in quality, delivery, cost and growth within its
businesses. The management process of Policy Deployment entails developing a
one year operating plan that reflects the long-term strategic objectives of
the Company. The purpose of this process is to link major objectives with
specific support plans throughout the Company's organization. Danaher Business
System's focus on associate involvement includes the concepts of creating a
team working environment and encouraging personnel development and creativity.
The Company's performance is measured in terms of customer satisfaction by its
improvement of quality, on-time delivery, cost position and service. Finally,
the Danaher Business System focuses on enhancing the profitability of the
Company to allow for long term growth. The Company began employing the Danaher
Business Systems in its core businesses in 1988 and created an executive level
function to train associates of existing and acquired businesses in 1992.
 
                              RECENT DEVELOPMENTS
 
ACQUISITION OF PACIFIC SCIENTIFIC
 
  On March 9, 1998, the Company acquired Pacific Scientific, an international
business that designs, manufacturers and markets motion control, process
control and safety equipment. The purchase price of this acquisition was
approximately $420 million in cash and approximately $60 million in assumed
debt. The Company has included Pacific Scientific's businesses in its
Process/Environmental Controls segment.
 
  Nearly half of Pacific Scientific's sales consists of electric motors,
drives and controls. These electric motors and controls are sold primarily to
original equipment manufacturers who incorporate them into a wide variety of
products. Pacific Scientific motors are used in factory automation, medical,
printing, plastic extrusion and molding, paper converting, vending, textile,
aerospace, fitness and many other types of equipment. Pacific Scientific's
process control products include devices to measure particles in liquids,

the rights of creditors and shareholders of the Company, to participate in any
distribution of assets of any Subsidiary upon its liquidation or

"Thirty-year Notes" and together with the Ten-year Notes, the "Offered
Securities"). Interest on the Offered Securities will accrue at the rate of
    % per annum on the Ten-year Notes and       % per annum on the Thirty-year
Notes and will be payable semi-annually in arrears on            and
          , commencing on           , 1999, to Holders of record on the

30-day months. Principal, premium, if any, and interest on the Offered
Securities will be payable at the office or agency of the Company maintained
for such purpose within the City and the State of New York or, at the option
of the Company, payment of interest may be made by check mailed to the Holders
of the Offered Securities at their respective addresses set forth in the
register of Holders of Offered Securities; provided that all payments of
principal, premium, if any, and interest with respect to Offered Securities,
the Holders of which have given wire transfer instructions to the Company,
will be required to be made by wire transfer of immediately available funds to
the accounts specified by the Holders thereof. Until otherwise designated by
the Company, the Company's office or agency in New York will be the office of
the Trustee maintained for such purpose. The Offered Securities will be issued
in denominations of $1,000 and integral multiples thereof.
 
OPTIONAL REDEMPTION
 
  The Ten-year Notes and the Thirty-year Notes will be redeemable, as a whole
or in part, at the option of the Company at any time, at a redemption price

redeemed and (b) the sum of the present values of the Remaining Scheduled
Payments (as hereinafter defined) thereon discounted to the redemption date on
a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Treasury Rate (as hereinafter defined) plus    basis points for
the Ten-year Notes and     basis points for the Thirty-year Notes, together in
all cases with accrued interest on the principal amount being redeemed to the

  The term "Remaining Scheduled Payments" means the remaining scheduled
payments of the principal of the Ten-year Notes or the Thirty-year Notes to be
redeemed and interest thereon that would be due after the related redemption

thereon will be reduced by the amount of interest accrued thereon to such
redemption date.
 
  The term "Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity (computed
as of the second business day immediately preceding such redemption date) of

Comparable Treasury Price for such redemption date.
 
  Notice of any redemption will be mailed at least 30 days but no more than 60
days before the redemption date to each Holder of Ten-year Notes or Thirty-
year Notes to be redeemed.
 
  Unless the Company defaults in payment of the redemption price, on and after
the applicable redemption date, interest will cease to accrue on the Ten-year
Notes or the Thirty-year Notes, as applicable, or portions thereof called for
redemption.
 
  There will be no mandatory sinking fund payments for either series of

CERTAIN COVENANTS
 
  LIMITATION ON SECURED DEBT
 
  The Company will not, and will not permit any Subsidiary to, create, assume,
or guarantee any Secured Debt without making effective provision for securing
the Offered Securities equally and ratably with such Secured Debt. This
covenant does not apply to debt secured by (i) purchase money mortgages
created to secure payment for the acquisition or construction of any property
including, but not limited to, any indebtedness incurred by the Company or a
Subsidiary prior to, at the time of, or within 180 days after the later of the
acquisition, the completion of construction (including any improvements on an
existing property) or the commencement of commercial operation of such
property, which indebtedness is incurred for the purpose of financing all or
any part of the purchase price of such property or construction or
improvements on such property, (ii) mortgages, pledges, liens, security
interest or encumbrances (collectively referred to herein as "security
interests") on property, or any conditional sales agreement or any title
retention with respect to property, existing at the time of acquisition

interests on property or shares of capital stock or indebtedness of any
corporation or firm existing at the time such corporation or firm becomes a
Subsidiary, (iv) security interests in property or shares of capital stock or
indebtedness of a corporation existing at the time such corporation is merged
into or consolidated with the Company or a Subsidiary or at the time of a
sale, lease, or other disposition of the properties of a corporation or firm
as an entirety or substantially as an entirety to the Company or a Subsidiary,
provided that no such security interests shall extend to any other Principal
Property of the Company or such Subsidiary prior to such acquisition
 
                                      11
<PAGE>
 
or to other Principal Property thereafter acquired other than additions or
improvements to the acquired property, (v) security interests on property of
the Company or a Subsidiary in favor of the United States of America or any
state thereof, or in favor of any other country, or any department, agency,
instrumentality or political subdivision thereof (including, without
limitation, security interests to secure indebtedness of the pollution control
or industrial revenue type) in order to permit the Company or any Subsidiary
to perform a contract or to secure indebtedness incurred for the purpose of
financing all or any part of the purchase price for the cost of constructing
or improving the property subject to such security interests or which is
required by law or regulation as a condition to the transaction of any
business or the exercise of any privilege, franchise or license, (vi) security
interests on any property or assets of any Subsidiary to secure indebtedness
owing by it to the Company or to another Subsidiary, (vii) any mechanics',
materialmen's, carriers' or other similar lien arising in the ordinary course

which are not yet due or which are being contested in good faith, (viii) any
security interest for taxes, assessments or government charges or levies not
yet delinquent, or already delinquent, but the validity of which is being
contested in good faith, (ix) any security interest arising in connection with
legal proceedings being contested in good faith, including any judgment lien
so long as execution thereof is being stayed, (x) landlords' liens on fixtures
located on premises leased by the Company or a Subsidiary in the ordinary
course of business, or (xi) any extension, renewal or replacement (or
successive extensions, renewals or replacements), in whole or in part, of any
security interest referred to in the foregoing clauses (i) to (x) inclusive.
 
  LIMITATION ON SALE AND LEASEBACK TRANSACTIONS
 
  The Indenture provides that the Company will not, and will not permit any
Subsidiary to, enter any lease longer than three years (excluding leases of
newly acquired, improved or constructed property) covering any Principal
Property of the Company or any Subsidiary that is sold to any other person in
connection with such lease (a "Sale and Leaseback Transaction"), unless either
(a) the Company or such Subsidiary would be entitled, without equally and
ratably securing the Offered Securities, to incur indebtedness secured by a
mortgage on the Principal Property leased pursuant to clauses (i) through (xi)
under "Limitation on Secured Debt" or (b) an amount equal to the value of the
Principal Property so leased is applied to the retirement, within 120 days of
the effective date of such arrangement, of indebtedness for borrowed money
incurred or assumed by the Company or a Subsidiary which is recorded as Funded
Debt (defined to include the Offered Securities and other long-term
indebtedness of the Company or any Subsidiary) as shown on the most recent
consolidated balance sheet of the Company and which in the case of such
indebtedness of the Company, is not subordinate and junior in right of payment
to the prior payment of the Offered Securities.
 
  EXEMPTED INDEBTEDNESS
 
  Notwithstanding the limitations on Secured Debt and Sale and Leaseback
Transactions described above, the Company and any one or more Subsidiaries
may, without securing the Offered Securities, issue, assume, or guarantee
Secured Debt or enter into any Sale and Leaseback Transaction which would
otherwise be subject to the foregoing restrictions, provided that, after
giving effect thereto, the aggregate amount of such Secured Debt then
outstanding (not including Secured Debt permitted under the foregoing
exceptions) and the Attributable Debt of Sale and Leaseback Transactions
(other than Sale and Leaseback Transactions in connection with clauses (a) or
(b) of the preceding paragraph) at such time does not exceed 15% of
Consolidated Net Assets.

assessments, water rates or similar charges or any amounts required to be paid

of the foregoing to the extent that such indebtedness or obligations are not
required by GAAP to be shown on the balance sheet of the Company.
 
  The term "Principal Property" means any manufacturing plant, warehouse,
office building or parcel of real property (including fixtures but excluding

Company and the Subsidiaries, other than any such plant, warehouse, office
building or parcel of real property or portion thereof which, in the opinion

  MERGER
 
  The Indenture provides that the Company may, without the consent of the
Holders, consolidate with, or sell, lease or convey all or substantially all
of its assets to, or merge into any other corporation, provided that, among
other things, in any such case, (i) the successor entity shall be a
corporation, partnership or trust organized and existing under the laws of the
United States, any State thereof or the District of Columbia and such entity
shall expressly assume the due and punctual payment of the principal of (and
premium, if any) and interest on all the applicable Offered Securities,
according to their tenor, and the due and punctual performance and observance
of all the covenants and conditions of the Indenture to be performed by the
Company by supplemental indenture satisfactory to the Trustee, executed and
delivered to the Trustee by such entity; and (ii) immediately after giving
effect to such transaction, no Default shall have occurred and be continuing.
 
  Other than the covenants described above, the Indenture does not contain any
covenants or other provisions designed to afford Holders of the Offered
Securities protection in the event of a takeover, recapitalization or a highly
leveraged transaction involving the Company.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Offered Securities of
any series ("Legal Defeasance") except for (i) the rights of Holders of
outstanding Offered Securities of such series to receive payments in respect
of the principal of, premium, if any, and interest on such Offered Securities
when such payments are due from the trust referred to below, (ii) the
Company's obligations with respect to the Offered Securities of such series
concerning issuing temporary Offered Securities, registration of Offered
Securities, mutilated, destroyed, lost or stolen Offered Securities and the
maintenance of an office or agency for payment and money for security payments
held in trust, (iii) the rights, powers, trusts, duties and immunities of the
Trustee, and the Company's obligations in connection therewith and (iv) the
Legal Defeasance provisions of the Indenture. In addition, the Company may, at
its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Offered Securities of such series. In the event Covenant Defeasance
occurs, certain events (not including non-payment, bankruptcy, receivership,
rehabilitation and insolvency events) described under "Events of Default" will
no longer constitute an Event of Default with respect to the Offered
Securities of such series.
 
  In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Offered Securities of such series, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, in such amounts
as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Offered Securities of such series on the stated
maturity or on the applicable redemption date, as the case may be, and the
Company must specify whether the Offered Securities of such series are being
defeased to maturity or to a particular redemption date; (ii) in the case of
Legal Defeasance, the Company shall have delivered to the Trustee an opinion
of counsel in the United States reasonably acceptable to the Trustee
confirming that (A) the Company has received from, or there has been published
by, the Internal Revenue Service a ruling or (B) since the date of the
Indenture, there has been a change in the applicable federal income tax law,
in either case to the effect that, and based thereon such opinion of counsel
shall confirm that, the Holders of the outstanding Offered Securities of such
series will not recognize income, gain or loss for federal income tax purposes
as a result of such Legal Defeasance and will be subject to federal income tax
on the same amounts, in the same manner and at the same times as would have
been the case if such Legal Defeasance had not occurred; (iii) in the case of
Covenant Defeasance, the Company shall have delivered to the Trustee an
opinion of counsel in the United States reasonably acceptable to the Trustee
 
                                      14
<PAGE>
 
confirming that the Holders of the outstanding Offered Securities of such
series will not recognize income, gain or loss for federal income tax purposes
as a result of such Covenant Defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would
have been the case if such Covenant Defeasance had not occurred; (iv) no
Default or Event of Default shall have occurred and be continuing on the date
of such deposit (other than a Default or Event of Default resulting from the
borrowing of funds to be applied to such deposit) or insofar as Events of
Default from bankruptcy or insolvency events are concerned, at any time in the
period ending on the 91st day after the date of deposit; (v) such Legal
Defeasance or Covenant Defeasance will not result in a breach or violation of,
or constitute a default under any material agreement or instrument (other than
the Indenture) to which the Company or any of its Subsidiaries is a party or
by which the Company or any of its Subsidiaries is bound; (vi) the Company
must have delivered to the Trustee an opinion of counsel to the effect that
after the 91st day following the deposit, the trust funds will not be subject
to the effect of any applicable bankruptcy, insolvency, reorganization or
similar laws affecting creditors' rights generally; (vii) the Company must
deliver to the Trustee an Officer's Certificate stating that the deposit was
not made by the Company with the intent of preferring the Holders of Offered
Securities of such series over the other creditors of the Company with the
intent of defeating, hindering, delaying or defrauding creditors of the
Company or others; and (viii) the Company must deliver to the Trustee an
Officer's Certificate and an opinion of counsel, each stating that all
conditions precedent provided for relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
  A Holder may transfer or exchange Offered Securities of each series in
accordance with the Indenture. The Registrar and the Trustee may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and the Company may require a Holder to pay any taxes and fees
required by law or permitted by the Indenture. The Company is not required to
transfer or exchange any Offered Security of any series selected for
redemption. Also, the Company is not required to transfer or exchange any
Offered Security of any series for a period of 15 days before a selection of
Offered Securities of that series to be redeemed.
 
  The registered Holder of any series of Offered Securities will be treated as
the owner of it for all purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
  Except as provided in the next two succeeding paragraphs, the Indenture or
the Offered Securities of any series may be amended or supplemented with the
consent of the Holders of such series of at least a majority in principal
amount of the Offered Securities of such series then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Offered Securities of such series), and
any existing default or compliance with any provision of the Indenture or the
Offered Securities of any series may be waived with the consent of the Holders
of a majority in principal amount of the then outstanding Offered Securities
of such series (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for, Offered Securities
of such series).
 
  Without the consent of each Holder of such series affected, an amendment or
waiver may not (with respect to any Offered Securities of such series held by
a non-consenting Holder): (i) reduce the principal amount of Offered
Securities of such series whose Holders must consent to an amendment,
supplement or waiver, (ii) reduce the principal of or change the fixed
maturity of any Offered Security of such series or alter the provisions with
respect to the redemption of the Offered Securities of such series, (iii)
reduce the rate of or extend the time for payment of interest on any Offered
Security of such series, (iv) waive a Default or Event of Default in the
payment of principal of or premium, if any, or interest on the Offered
Securities of such series (except a rescission of acceleration of the Offered
Securities by the Holders of such series of at least a majority in aggregate
principal amount of the Offered Securities of such series and a waiver of the
payment default that resulted from such acceleration), (v) make any Offered
Security of such series payable in money other than that stated in the Offered
Securities of such series, (vi) make any change in the provisions of the
Indenture relating to waivers of past Defaults or the rights of Holders of
Offered Securities of such series to receive payments of
 
                                      15
<PAGE>
 
principal of or premium, if any, or interest on the Offered Securities of such
series, (vii) waive a redemption payment with respect to any Offered Security
of such series or (viii) make any change in the foregoing amendment and waiver
provisions.
 
  Notwithstanding the foregoing, without the consent of any Holder of Offered
Securities of any series, the Company and the Trustee may amend or supplement
the Indenture or the Offered Securities of any series to, among other things,
cure any ambiguity, defect or inconsistency, to provide for uncertificated
Offered Securities of any series in addition to or in place of certificated
Offered Securities, to provide for the assumption of the Company's obligations
to Holders of Offered Securities of any series in the case of a merger or
consolidation or sale of all or substantially all of the Company's assets, to
make any change that would provide any additional rights or benefits to the
Holders of Offered Securities of any series or that does not adversely affect
the legal rights under the Indenture of any such Holder, or to comply with
requirements of the SEC in order to effect or maintain the qualification of
the Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
  The Indenture contains certain limitations on the rights of the Trustee,
should it be a creditor of the Company, to obtain payment of claims in certain
cases, or to realize on certain property received in respect of any such claim
as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest (as defined in
the Trust Indenture Act) it must eliminate such conflict within 90 days, apply
to the SEC for permission to continue or resign.
 
EVENTS OF DEFAULT
 
  As to any series of Offered Securities, an Event of Default is defined in
the Indenture as being: (a) default for 30 days in payment of any interest on
the Offered Securities of such series; (b) failure to pay principal or premium
with respect to the Offered Securities of such series, if any, when due; (c)
failure to observe or perform any other covenant in the Indenture or Offered
Securities of any series (other than a covenant or warranty, a default in
whose performance or whose breach is specifically dealt with in the section of
the Indenture governing Events of Default), if such failure continues for 90
days after written notice by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Offered Securities of such series then
outstanding; (d) certain events of bankruptcy, insolvency, receivership or
reorganization; or (e) any other Event of Default provided with respect to
Offered Securities of that series. The Trustee or the Holders of 25% in
aggregate principal amount of the outstanding Offered Securities of any series
may declare the Offered Securities of such series immediately due and payable
upon the occurrence of any Event of Default (after expiration of any
applicable grace period); in certain cases, the Holders of a majority in
principal amount of the Offered Securities of any series then outstanding may
waive any past default and its consequences, except a default in the payment
of principal, premium, if any, or interest.
 
  The Indenture provides that the Trustee shall, within 90 days after the
occurrence of a default with respect to any such series for which there are
Offered Securities outstanding which is continuing, give to the Holders of
such Offered Securities notice of all uncured defaults known to it (the term
default to include the events specified above without grace periods); provided
that, except in the case of default in the payment of principal (or premium,
if any) or interest on any of the Offered Securities of any series, the
Trustee shall be protected in withholding such notice if it in good faith
determines that the withholding notice is in the interest of the Offered
Security Holders.
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee in case an Event of Default with respect to any series of such Offered
Securities shall occur and be continuing, the Indenture provides that the
Trustee shall be under no obligation to exercise any of its rights or powers
under the Indenture at the request, order or direction of any of the Holders
of Offered Securities outstanding of any series unless such Holders shall have
offered to the Trustee reasonable indemnity. The right of a Holder to
institute a proceeding with respect to the Indenture is subject to certain
conditions precedent including notice and indemnity to the Trustee, but the
 
                                      16
<PAGE>
 
Holder has a right to receipt of principal, premium, if any, and interest
(subject to certain limitations with respect to defaulted interest) on their
due dates or to institute suit for the enforcement thereof.
 
  So long as the Offered Securities of any series remain outstanding the
Company will be required to furnish annually to the Trustee an Officer's
Certificate stating whether, to the best of the knowledge of the signers, the
Company is in default under any of the provisions of the Indenture, and
specifying all such defaults, and the nature thereof, of which they have
knowledge. The Company will also be required to furnish to the Trustee copies
of certain reports filed by the Company with the SEC.
 
  The Holders of a majority in principal amount of the Offered Securities
outstanding of such series will have the right to direct the time, method and
place for conducting any proceeding for any remedy available to the Trustee,
or exercising any power or trust conferred on the Trustee, provided that such
direction shall be in accordance with law and the provisions of the Indenture,
and, provided, further, that the Trustee may decline to follow any such
direction if the Trustee in good faith shall, by a responsible officer of the
Trustee, determine that the proceeding would involve the Trustee in personal
liability. The Trustee will be under no obligation to act in accordance with
such direction unless such Holders shall have offered the Trustee reasonable
security or indemnity against costs, expenses and liabilities which may be
incurred thereby.
 
DEPOSITORY PROCEDURES
 
  Except as set forth in the next paragraph, the Offered Securities of any
series to be resold as set forth herein will initially be issued in the form
of one or more Global Securities (the "Global Securities"). The Global
Securities will be deposited on the date of the closing of the sale of the
Offered Securities offered hereby (the "Closing Date") with, or on behalf of,
The Depository Trust Company ("DTC") and registered in the name of Cede & Co.,
as nominee of DTC (such nominee being referred to herein as the "Global
Securities Holder").
 
  DTC is a limited-purpose trust company that was created to hold securities
for its participating organizations (collectively, the "Participants") and to
facilitate the clearance and settlement of transactions in those securities
between Participants through electronic book-entry changes in accounts of its
Participants. The Participants include securities brokers and dealers
(including the Underwriters), banks, trust companies, clearing corporations
and certain other organizations. Access to DTC's system is also available to
other entities such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either
directly or indirectly (collectively, the "Indirect Participants"). Persons
who are not Participants may beneficially own securities held by or on behalf
of DTC only through the Participants or the Indirect Participants. The
ownership interests in, and transfers of ownership interests in, each security
held by or on behalf of DTC are recorded on the records of the Participants
and Indirect Participants.
 
  The Company expects that pursuant to procedures established by DTC, (i) upon
deposit of the Global Securities, DTC will credit the accounts of Participants
designated by the Underwriters with portions of the principal amount of the
Global Securities and (ii) ownership of such interests in the Global
Securities will be shown on, and the transfer of ownership thereof will be
effected only through, records maintained by DTC (with respect to the
interests of the Participants) or by the Participants and the Indirect
Participants (with respect to other owners of beneficial interest in the
Global Securities). Prospective purchasers are advised that the laws of some
states require that certain persons take physical delivery in definitive form
of securities that they own. Consequently, the ability to transfer Offered
Securities of any series evidenced by the Global Securities will be limited to
such extent.
 
  So long as the Global Securities Holder is the registered owner of any
Offered Securities, the Global Securities Holder will be considered the sole
Holder under the Indenture of any Offered Securities evidenced by the Global
Securities. Beneficial owners of Offered Securities evidenced by the Global
Securities will not be considered the owners or Holders thereof under the
Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any
aspect of the records of DTC or for maintaining, supervising or reviewing any
records of DTC relating to the Offered Securities of any series.
 
 
                                      17
<PAGE>
 
  Payments in respect of the principal of, premium, if any, and interest, if
any, on any Offered Securities registered in the name of the Global Securities
Holder on the applicable record date will be payable by the Trustee to or at
the direction of the Global Securities Holder in its capacity as the
registered Holder under the Indenture. Under the terms of the Indenture, the
Company and the Trustee may treat the persons in whose names Offered
Securities, including Global Securities, are registered as the owners thereof
for the purpose of receiving such payments. Consequently, neither the Company
nor the Trustee has or will have any responsibility or liability for the
payment of such amounts to beneficial owners of Offered Securities. The
Company believes, however, that it is currently the policy of DTC to
immediately credit the accounts of the relevant Participants with such
payments, in amounts proportionate to their respective holdings of beneficial
interests in the relevant security as shown on the records of DTC. Payments by
Participants and Indirect Participants to the beneficial owners of Offered
Securities will be governed by standing instructions and customary practice
and will be the responsibility of the Participants or the Indirect
Participants.
 
CERTIFICATED SECURITIES
 
  Subject to certain conditions, any person having a beneficial interest in a
Global Security may, upon the request to the Trustee, exchange such beneficial
interest for Offered Securities in the form of certificated securities. Upon
any such issuance, the Trustee is required to register such certificated
securities in the name of, and cause the same to be delivered to, such person
or persons (or the nominee of any thereof). In addition, if (i) the Company
notifies the Trustee in writing that DTC is no longer willing or able to act
as a depository and the Company is unable to locate a qualified successor
within 90 days or (ii) the Company, at its option, notifies the Trustee in
writing that it elects to cause the issuance of Offered Securities of any
series in the form of certificated securities under the Indenture, then, upon
surrender by the Global Securities Holder of its Global Securities, Offered
Securities in such form will be issued to each person that the Global
Securities Holder and DTC identify as being the beneficial owner of the
related Offered Securities.
 
  Neither the Company nor the Trustee will be liable for any delay by the
Global Securities Holder or DTC in identifying the beneficial owners of
Offered Securities and the Company and the Trustee may conclusively rely on,
and will be protected in relying on, instructions from the Global Securities
Holder or DTC for all purposes.
 
SAME DAY SETTLEMENT AND PAYMENT
 
  The Indenture requires that payments in respect of the Offered Securities
represented by the Global Security (including principal, premium, if any, and
interest) be made by wire transfer of immediately available next day funds to
the accounts specified by the Global Securities Holder. With respect to
certificated securities, the Company will make all payments of principal,
premium, if any, and interest, by wire transfer of immediately available funds
to the accounts specified by the Holders thereof or, if no such account is
specified, by mailing a check to each such Holder's registered address. The
Company expects that secondary trading in the certificated securities will
also be settled in immediately available funds.

  The Company has been advised by the Underwriters that they propose initially
to offer the Ten-year Notes and the Thirty-year Notes to the public at the
public offering price set forth on the cover page of this Prospectus, and to
certain dealers at such price less a concession not in excess of     % of the
principal amount of the Ten-year Notes and      % of the principal amount of
the Thirty-year Notes. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of     % of the principal amount of the
Ten-year Notes and      % of the principal amount of the Thirty-year Notes to
certain other dealers.
 
  In connection with this offering, certain Underwriters and their affiliates
may engage in transactions that stabilize, maintain or otherwise affect the
market price of the Offered Securities. Such transactions may include
stabilization transactions effected in accordance with Rule 104 of Regulation
M, pursuant to which such persons may bid for or purchase the Offered
Securities for the purpose of stabilizing their market price. The Underwriters
may also create a short position for the account of the Underwriters by
selling more of the Offered Securities in connection with the offering than
they are committed to purchase from the Company, and in such case may purchase
the Offered Securities in the open market following completion of the offering
to cover such short position. Any of the transactions described in this
paragraph may result in the maintenance of the price of the Offered Securities
at a level above that which might otherwise prevail in the open market. None
of the transactions described in this paragraph is required, and, if they are
undertaken, they may be discontinued at any time.
 
  The Company does not presently intend to list the Offered Securities on any
exchange. The Company has been advised by the Underwriters that they intend to
make a market in the Offered Securities but that they are not obligated to do
so and may discontinue market making at any time without notice. No assurance
can be given as to the liquidity of the trading market for the Offered
Securities.
 
  The Underwriting Agreement provides that the Company will indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933, as amended, or contribute to payments the
Underwriters may be required to make in respect thereof.
 
  In the ordinary course of their respective business, the Underwriters and
their respective affiliates have engaged and may in the future engage in
commercial banking and investment banking transactions with the Company. In
addition, the Trustee under the Indenture is an affiliate of First Chicago
Capital Markets, Inc., one of the Underwriters.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Under Section 145 of the General Corporation Law of the State of Delaware
(the "DGCL"), a corporation may indemnify its directors, officers, employees
and agents and its former directors, officers, employees and agents and those
who serve, at the corporation's request, in such capacities with another
enterprise, against expenses (including attorney's fees), as well as
judgments, fines and settlements in nonderivative lawsuits, actually and
reasonably incurred in connection with the defense of any action, suit or
proceeding in which they or any of them were or are made parties or are
threatened to be made parties by reason of their serving or having served in
such capacity. The DGCL provides, however, that such person must have acted in
good faith and in a manner he or she reasonably believed to be in (or not
opposed to) the best interests of the corporation and, in the case of a
criminal action, such person must have had no reasonable cause to believe his
or her conduct was unlawful. In addition, the DGCL does not permit
indemnification in an action or suit by or in the right of the corporation,
where such person has been adjudged liable to the corporation, unless, and
only to the extent that, a court determines that such person fairly and
reasonably is entitled to indemnity for costs the court deems proper in light
of liability adjudication. Indemnity is mandatory to the extent a claim, issue
or matter has been successfully defended.
 
  Article Ten of the Company's Certificate of Incorporation provides that the
Company will indemnify its directors and officer to the full extent permitted
by law and that no director shall be liable for monetary damages to the
Registrant or its stockholders for any breach of fiduciary duty, except to the
extent provided by applicable law (i) for any breach of the director's duty of
loyalty to the Registrant or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) pursuant to Section 174 of the DGCL, or (iv) for any transaction
from which such director derived an improper personal benefit. Article Eight
of the Company's Bylaws provides that the Company will indemnify directors,
officers, employees or agents of the Company in non-derivative claims if such
person acted in good faith and in a manner such person reasonably believed to
be in or not opposed to the best interests of the Company, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. For non-derivative claims, termination of any action,
suit or proceeding by judgment, order, settlement, conviction or upon a plea
of nolo contendere or its equivalent, shall not, in itself, create a
presumption that the person did not act in good faith and in a manner which
such person believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that such person's conducts was unlawful. For
derivative claims, Article Eight of the Company Bylaws provides that the
<PAGE>
 
Company will indemnify directors, officers, employees or agents of the Company
if such person acted in good faith and in a manner such person reasonably
believed to be in or not opposed to the best interests of the Company; except
that no indemnification shall be made in respect of any claim, issue or matter
as to which such person shall have been adjudged to be liable to the Company
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

                                 UNDERTAKINGS
 
The Registrant hereby undertakes:
 
  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the SEC such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
<PAGE>
 
The undersigned Registrant hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
<PAGE>
 
                            SIGNATURE OF REGISTRANT
 
  Pursuant to the requirements of the Securities Act, the Registrant certifies
that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the District of Columbia on September 17, 1998.

               ----------                                                   
that:

          (a) Prior to the termination of the offering of the Securities, the
     Company will not file any amendment of the Registration Statement or
     supplement to the Prospectus or any Rule 462(b) Registration Statement
     unless the Company has furnished you a copy for your review prior to filing
     and will not file any such proposed amendment or supplement to which you
     reasonably object.  Subject to the foregoing sentence, if the filing of the
     Prospectus is required under Rule 424(b), the Company will cause the
     Prospectus, properly completed, and any supplement thereto to be filed with
     the Commission pursuant to the applicable paragraph of Rule 424(b) within
     the time period prescribed and will provide evidence satisfactory to the
     Representatives of such timely filing.  The Company will promptly advise
     the Represen  tatives (1) when the Prospectus, and any supplement thereto,
     shall have been filed (if required) with the Commission pursuant to Rule
     424(b) or when any Rule 462(b) Registration Statement shall have been filed
     with the Commission, (2) when, prior to termination of the offering of the
     Securities, any amendment to the Registration Statement shall have been
     filed or become effective, (3) of any request by the Commission or its
     staff for any amendment of the Registration Statement, or any Rule 462(b)
     Registration Statement, or for any supplement to the Prospectus or for any
     additional information, (4) of the issuance by the Commission of any stop
     order suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose and (5) of
     the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the initiation or threatening of any proceeding for such
     purpose.  The Company will use its best efforts to prevent the issuance of
     any such stop order or the suspension of any such qualification and, if
     issued, to obtain as soon as possible the withdrawal thereof.

                                       9

          (b) If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Prospectus as then supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or if it shall be necessary to amend
     the Registration Statement or supplement the Prospectus to comply with the
     Act or the Exchange Act or the respective rules thereunder, the Company
     promptly will (1) notify the Representatives of such event; (2) prepare and
     file with the Commission, subject to the second sentence of paragraph (a)
     of this Section 5, an amendment or supplement which will correct such
     statement or omission or effect such compliance and (3) supply any
     supplemented Prospectus to you in such quantities as you may reasonably
     request.

          (c) As soon as practicable, the Company will make generally available
     to its security holders and to the Representatives an earnings statement or
     statements of the Company and its subsidiaries which will satisfy the
     provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d) The Company will furnish to each of the Representatives and
     counsel for the Underwriters, without charge, a signed copy of the
     Registration Statement (including exhibits thereto) and to each other
     Underwriter a copy of the Registration Statement (without exhibits thereto)
     and, so long as delivery of a prospectus by an Underwriter or dealer may be
     required by the Act, as many copies of each Preliminary Prospectus and the
     Prospectus and any supplement thereto as the Representatives may reasonably
     request.  The Company will pay the expenses of printing or other production
     of all documents relating to the offering.

          (e) The Company will arrange, if necessary, for the qualification of
     the Securities for sale under the laws of such jurisdictions as the
     Representatives may designate, will maintain such qualifications in effect
     so long as required for the distribution of the Securities and will pay any
     fee of the National Association of Securities Dealers, Inc., in connection
     with its review of the offering; provided that in no event shall the
     Company be obligated to qualify to do business in any jurisdiction where it
     is not now so qualified or to take any action that would subject it to
     service of process in suits, other than those arising out of the offering
     or sale of the Securities in any jurisdiction where it is not now so
     subject.

          (f) The Company will not, for the period from the Execution Time to
     and including the Closing Date, offer, sell or contract to sell, or
     otherwise dispose of (or enter into any transaction which is designed to,
     or might reasonably be expected to, result in the disposition (whether by
     actual disposition or effective economic disposition due to cash settlement
     or otherwise) by the Company or any affiliate of the Company or any person
     in privity with the Company or any affiliate of the Company) directly or
     indirectly, or announce the offering of any debt securities issued or
     guaranteed by the Company (other than the Securities).

                                       10

          (g) The Company will not take, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result in, under the Exchange Act or otherwise, stabilization
     or manipulation of the price of any security of the Company to facilitate
     the sale or resale of the Securities.
 
          (h) The Company will use the proceeds of the Securities as described
     in the section entitled "Use of Proceeds" in the Prospectus.

          6.   Conditions to the Obligations of the Underwriters.  The
               -------------------------------------------------      
obligations of the Underwriters to purchase the Securities shall be subject to
the accuracy of the representations and warranties on the part of the Company
contained herein as of the Execution Time and the Closing Date, to the accuracy
of the statements of the Company made in any certificates pursuant to the
provisions hereof, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

          (a) If filing of the Prospectus, or any supplement thereto, is
     required pursuant to Rule 424(b), the Prospectus, and any such supplement,
     will have been filed in the manner and within the time period required by
     Rule 424(b); and no stop order suspending the effectiveness of the
     Registration Statement shall have been issued; and no proceedings for that
     purpose shall have been instituted or threatened.

          (b) The Company shall have furnished to the Representatives the
     opinion of Wilmer, Cutler & Pickering, counsel for the Company, dated the
     Closing Date and addressed to the Representatives, to the effect that:

               (i) the Company and each subsidiary that would constitute a
          significant subsidiary (as such term is defined in Rule 1-02 of
          Regulation S-X) as of the date of this Agreement (individually a
          "Subsidiary" and collectively the "Subsidiaries") has been duly
          incorporated and is validly existing as a corporation in good standing
          under the laws of the jurisdiction in which it is chartered or
          organized, with full corporate power and authority to own or lease, as
          the case may be, its properties and conduct its business as described
          in the Prospectus, and is duly qualified to do business as a foreign
          corporation and is in good standing under the laws of each
          jurisdiction which requires such qualification, except, in each such
          case, that could not reasonably be expected to have a Material Adverse
          Effect.

               (ii) all the outstanding shares of capital stock of each
          Subsidiary have been duly and validly authorized and issued and are
          fully paid and nonassessable, and, except as may be otherwise set
          forth in the Prospectus, all outstanding shares of capital stock of
          the Subsidiaries are owned by the Company either directly or through
          wholly owned subsidiaries free and clear of any perfected security
          interest and, to the knowledge of such counsel, after due inquiry, any
          other security interest, claim, lien or encumbrance;

                                       11
<PAGE>
 
               (iii)  the Company's authorized equity capitalization is as set
          forth in the Prospectus; the Securities conform in all material
          respects to the description thereof contained in the Prospectus;

               (iv) the Indenture has been duly authorized, executed and
          delivered by the Company and (assuming the due execution and delivery
          thereof by the Trustee) is a valid and binding instrument enforceable
          against the Company in accordance with its terms, except as
          enforcement thereof may be limited by bankruptcy, insolvency,
          reorganization, moratorium or other laws relating to or affecting
          enforcement of creditors' rights generally or by general equity
          principles; the Indenture has been duly qualified under the Trust
          Indenture Act, and the Securities have been duly authorized by the
          Company and, when executed and authenticated in accordance with the
          provisions of the Indenture and delivered to and paid for by the
          Underwriters pursuant to this Agreement and the Indenture, will
          constitute legal, valid and binding obligations of the Company
          enforceable in accordance with their terms, except as enforcement
          thereof may be limited by bankruptcy, insolvency, reorganization,
          moratorium or other laws relating to or affecting enforcement of
          creditors' rights generally or by general equity principles, and
          entitled to the benefits of the Indenture;

               (v) to the knowledge of such counsel, there is no pending or
          threatened action, suit or proceeding by or before any court or
          governmental agency, authority or body or any arbitrator involving the
          Company or any of its subsidiaries or its or their property of a
          character required to be disclosed in the Registration Statement which
          is not adequately disclosed in the Prospectus, and to the knowledge of
          such counsel, there is no franchise, contract or other document of a
          character required to be described in the Registration Statement or
          Prospectus, or to be filed as an exhibit thereto, which is not
          described or filed as required; and the statements included in the
          Prospectus under the headings "Description of Offered Securities"
          fairly summarize the matters therein described;

               (vi) the Registration Statement has become effective under the
          Act; any required filing of the Prospectus, and any supplements
          thereto, pursuant to Rule 424(b) has been made in the manner and
          within the time period required by Rule 424(b); to the knowledge of
          such counsel, no stop order suspending the effectiveness of the
          Registration Statement has been issued, no proceedings for that
          purpose have been instituted or  threatened and the Registration
          Statement and the Prospectus (other than the financial statements,
          related schedules and other financial information contained therein,
          as to which such counsel need express no opinion) comply as to form in
          all material respects with the applicable requirements of the Act, the
          Exchange Act and the Trust Indenture Act and the respective rules
          thereunder; and such counsel has no reason to believe that on the
          Effective Date or at the Execution Time the Registration Statement
          contained any untrue statement of a material fact or omitted to state
          any material fact required to be stated therein or 

                                       12
<PAGE>
 
          necessary to make the statements therein not misleading, or that the
          Prospectus, as of its date and on the Closing Date, included or
          includes any untrue statement of a material fact or omitted or omits
          to state a material fact necessary to make the statements therein, in
          the light of the circumstances under which they were made, not
          misleading (in each case, other than the financial statements, related
          schedules and other financial information contained therein, as to
          which such counsel need express no view);

               (vii)  this Agreement has been duly authorized, executed and
          delivered by the Company;

               (viii)  the Company is not and, after giving effect to the
          offering and sale of the Securities and the application of the
          proceeds thereof as described in the Prospectus, will not be an
          "investment company" as defined in the Investment Company Act of 1940,
          as amended;
 
               (ix) no consent, approval, authorization, filing with or order of
          any court or governmental agency or body is required in connection
          with the transactions contemplated herein, except such as have been
          obtained under the Act and such as may be required under the blue sky
          laws of any jurisdiction in connection with the purchase and
          distribution of the Securities by the Underwriters in the manner
          contemplated in the Agreement and in the Prospectus;

               (x) neither the execution and delivery of the Indenture, the
          issue and sale of the Securities, nor the consummation of any other of
          the transactions herein contemplated nor the fulfillment of the terms
          hereof will conflict with, result in a breach or violation or
          imposition of any lien, charge or encumbrance upon any property or
          assets of the Company or its subsidiaries pursuant to (i) the charter
          or by-laws of the Company or its Subsidiaries; (ii) the terms of any
          indenture, contract, lease, mortgage, deed of trust, note agreement,
          loan agreement or other agreement, obligation, condition, covenant or
          instrument to which the Company or its subsidiaries is a party or
          bound or to which its or their property is subject; or (iii) any
          statute, law, rule, regulation, judgment, order or decree applicable
          to the Company or its subsidiaries of any court, regulatory body,
          administrative agency, governmental body, arbitrator or other
          authority having jurisdiction over the Company or its subsidiaries or
          any of its or their properties, other than, in the case of clauses
          (ii) and (iii), any breach, violation, lien, charge or encumbrance
          that could reasonably be expected to have a Material Adverse Effect;
          and

               (xi) no holders of securities of the Company have rights to the
          registration of such securities under the Registration Statement.

                                       13

     In rendering such opinion, such counsel may rely (A) as to matters
     involving the application of laws of any jurisdiction other than the State
     of Delaware, the State of New York or the Federal laws of the United
     States, to the extent they deem proper and specified in such opinion, upon
     the opinion of other counsel of good standing whom they believe to be
     reliable and who are satisfactory to counsel for the Underwriters and (B)
     as to matters of fact, to the extent they deem proper, on certificates of
     responsible officers of the Company and public officials.  References to
     the Prospectus in this paragraph (b) include any supplements thereto at the
     Closing Date.

          (c) The Representatives shall have received from Latham & Watkins,
     counsel for the Underwriters, such opinion or opinions, dated the Closing
     Date and addressed to the Representatives, with respect to the issuance and
     sale of the Securities, the Indenture, the Registration Statement, the
     Prospectus (together with any supplement thereto) and other related matters
     as the Representatives may reasonably require, and the Company shall have
     furnished to such counsel such documents as they request for the purpose of
     enabling them to pass upon such matters.

          (d) The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the Chairman of the Board or the
     President and the principal financial or accounting officer of the Company,
     dated the Closing Date, to the effect that the signers of such certificate
     have carefully examined the Registration Statement, the Prospectus, any
     supplements to the Prospectus and this Agreement and that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date,
          and the Company has complied with all the agreements and satisfied all
          the conditions on its part to be performed or satisfied at or prior to
          the Closing Date;

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge,
          threatened; and

               (iii)  since the date of the most recent financial statements
          included or incorporated by reference in the Prospectus (exclusive of
          any supplement thereto), there has been no material adverse change in
          the condition (financial or otherwise), prospects, earnings, business
          or properties of the Company and its subsidiaries, taken as a whole,
          whether or not arising from transactions in the ordinary course of
          business, except as set forth in or contemplated in the Prospectus
          (exclusive of any supplement thereto).

          (e) The Company shall have caused Arthur Andersen LLP to have
     furnished to the Representatives at the Execution Time and at the Closing
     Date, letters, dated respectively as of the Execution Time and as of the
     Closing Date, in form and substance satisfactory to 

                                       14
<PAGE>
 
     the Representatives, confirming that they are independent accountants
     within the meaning of the Act and the Exchange Act and the respective
     applicable published rules and regulations thereunder and that they have
     performed a review of the unaudited interim financial information of the
     Company for the six-month period ended June 26, 1998, in accordance with
     Statement on Accounting Standards No. 71 and stating in effect that:

               (i) in their opinion the audited financial statements and
          financial statement schedules and pro forma financial data included or
          incorporated by reference in the Registration Statement and the
          Prospectus and reported on by them comply as to form in all material
          respects with the applicable accounting requirements of the Act and
          the Exchange Act and the related published rules and regulations;

               (ii) on the basis of a reading of the latest unaudited financial
          statements made available by the Company and its subsidiaries;
          carrying out certain specified procedures (but not an examination in
          accordance with generally accepted auditing standards) which would not
          necessarily reveal matters of significance with respect to the
          comments set forth in such letter; a reading of the minutes of the
          meetings of the stockholders, directors and any committees of the
          directors of the Company and the Subsidiaries; and inquiries of
          certain officials of the Company who have responsibility for financial
          and accounting matters of the Company and its subsidiaries as to
          transactions and events subsequent to December 31, 1997, nothing came
          to their attention which caused them to believe that:

                    (1) any unaudited financial statements included or
               incorporated in the Registration Statement and the Prospectus do
               not comply as to form in all material respects with applicable
               accounting requirements and with the published rules and
               regulations of the Commission with respect to financial
               statements included or incorporated by reference in quarterly
               reports on Form 10-Q under the Exchange Act; and said unaudited
               financial statements are not in conformity with generally
               accepted accounting principles applied on a basis substantially
               consistent with that of the audited financial statements included
               or incorporated in the Registration Statement and the Prospectus;

                    (2) with respect to the period subsequent to June 26, 1998,
               there were any changes, at a specified date not more than five
               days prior to the date of the letter, in the long-term debt of
               the Company and its subsidiaries or capital stock of the Company
               or decreases in the stockholders' equity of the Company as
               compared with the amounts shown on the June 26, 1998 consolidated
               balance sheet included or incorporated by reference in the
               Registration Statement and the Prospectus, or for the period from
               June 26, 1998 to such specified date there were any decreases, as
               compared with the corresponding period in the preceding year in

                                       15
<PAGE>
 
               net sales or income before income taxes or in total or per share
               amounts of net income of the Company and its subsidiaries, except
               in all instances for changes or decreases set forth in such
               letter, in which case the letter shall be accompanied by an
               explanation by the Company as to the significance thereof unless
               said explanation is not deemed necessary by the Representatives;

               (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Registration Statement and the Prospectus and in Exhibit
          12 to the Registration Statement, including the information included
          or incorporated in Items 1, 6, 7 and 11 of the Company's Annual Report
          on Form 10-K, incorporated by reference in the Registration Statement
          and the Prospectus, and the information included in the "Management's
          Discussion and Analysis of Financial Condition and Results of
          Operations" included or incorporated in the Company's Quarterly
          Reports on Form 10-Q, incorporated by reference in the Registration
          Statement and the Prospectus, and the Current Reports of the Company
          on Form 8-K dated March 9, 1998 and dated July 9, 1998, incorporated
          by reference in the Registration Statement and the Prospectus, agrees
          with the accounting records of the Company and its subsidiaries,
          excluding any questions of legal interpretation; and

               (iv) on the basis of a reading of the unaudited pro forma
          financial statements included or incorporated by reference in the
          Registration Statement and the Prospectus (the "pro forma financial
          statements"); carrying out certain specified procedures; inquiries of
          certain officials of the Company who have responsibility for financial
          and accounting matters; and proving the arithmetic accuracy of the
          application of the pro forma adjustments to the historical amounts in
          the pro forma financial statements, nothing came to their attention
          which caused them to believe that the pro forma financial statements
          do not comply in form in all material respects with the applicable
          accounting requirements of Rule 11-02 of Regulation S-X or that the
          pro forma adjustments have not been properly applied to the historical
          amounts in the compilation of such statements.

          References to the Prospectus in this paragraph (e) include any
     supplement thereto at the date of the letter.

          (f) Subsequent to the Execution Time, there shall not have been (i)
     any change or decrease specified in the letter or letters referred to in
     paragraph (e) of this Section 6 or (ii) any change, or any development
     involving a prospective change, in or affecting the condition (financial or
     otherwise), earnings, business or properties of the Company and its
     subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, except as set forth in or contemplated in

                                       16

     the Prospectus (exclusive of any supplement thereto) the effect of which,
     in any case referred to in clause (i) or (ii) above, is, in the sole
     judgment of the Representatives, so material and adverse as to make it
     impractical or inadvisable to proceed with the offering or delivery of the
     Securities as contemplated by the Registration Statement (exclusive of any
     amendment thereof) and the Prospectus (exclusive of any supplement
     thereto).
 
          (g) The Company shall have caused Ernst & Young LLP, with respect to
     Fluke Corporation, and Deloitte & Touche LLP, with respect to Pacific
     Scientific Corporation, to have furnished to the Representatives at the
     Execution Time, letters, dated as of the Execution Time, in form and
     substance reasonably satisfactory to the Representatives, confirming that
     they are independent accountants within the meaning of the Act and the
     Exchange Act and the respective applicable published rules and regulations
     thereunder.

          (h) Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Act) or any notice given of any intended
     or potential decrease in any such rating or of a possible change in any
     such rating that does not indicate the direction of the possible change.

          (i) Prior to the Closing Date, the Company shall have furnished to the
     Representatives such further information, certificates and documents as the
     Representatives may reasonably request.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancellation shall be given to the Company in writing or by telephone or
facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be
delivered at the office of Latham & Watkins, counsel for the Underwriters, at
233 South Wacker Drive, Chicago, Illinois 60606, on the Closing Date.

          7.   Reimbursement of Underwriters' Expenses.  If the sale of the
               ---------------------------------------                     
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally through Salomon Smith Barney Inc. on demand for all out-of-pocket
expenses (including reasonable fees and disbursements of counsel) that shall
have been incurred by them in connection with the proposed purchase and sale of
the Securities.

          8.   Indemnification and Contribution.
               -------------------------------- 
 
          (a) The Company agrees to indemnify and hold harmless each
     Underwriter, the directors, officers, employees and agents of each
     Underwriter and each person who controls any Underwriter within the meaning
     of either the Act or the Exchange Act against any and all losses, claims,
     damages or liabilities, joint or several, to which they or any of them may
     become subject under the Act, the Exchange Act or other Federal or state
     statutory law or regulation, at common law or otherwise, insofar as such
     losses, claims, damages or liabilities (or actions in respect thereof)
     arise out of or are based upon any untrue statement or alleged untrue
     statement of a material fact contained in the registration statement for
     the registration of the Securities as originally filed or in any amendment
     thereof, or in any Preliminary Prospectus or the Prospectus, or in any
     amendment thereof or supplement thereto, or arise out of or are based upon
     the omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein, in the
     case of the Preliminary Prospectus and the Prospectus, or in any amendment
     thereof or supplement thereto, in light of the circumstances in which they
     were made, not misleading, and agrees to reimburse each such indemnified
     party, as incurred, for any legal or other expenses reasonably incurred by
     them in connection with investigating or defending any such loss, claim,
     damage, liability or action;  provided, however, that the Company will not
                                   --------  -------          
     be liable in any such case to the extent that any such loss, claim, damage
     or liability arises out of or is based upon any such untrue statement or
     alleged untrue statement or omission or alleged omission made therein in
     reliance upon and in conformity with written information furnished to the
     Company by or on behalf of any Underwriter through the Representatives
     specifically for inclusion therein. This indemnity agreement will be in
     addition to any liability which the Company may otherwise have.

          (b) Each Underwriter severally and not jointly agrees to indemnify and
     hold harmless the Company, each of its directors, each of its officers who
     signs the Registration Statement, and each person who controls the Company
     within the meaning of either the Act or the Exchange Act, to the same
     extent as the foregoing indemnity from the Company to each Underwriter, but
     only with reference to written information relating to such Underwriter
     furnished to the Company by or on behalf of such Underwriter through the
     Representatives specifically for inclusion in the documents referred to in
     the foregoing indemnity; and agrees to reimburse the Company, as incurred,
     for any legal or other expenses reasonably incurred by the Company in
     connection with investigating or defending any such loss, claim, damage,
     liability or action.  This indemnity agreement will be in addition to any
     liability which any Underwriter may otherwise have.  The Company
     acknowledges that the statements set forth in the last paragraph of the
     cover page regarding delivery of the Securities, the legend in block
     capital letters on page 1 related to stabilization, syndicate covering
     transactions and penalty bids and, under the heading "Underwriting" (i) the
     sentences related to concessions and reallowances and (ii) the paragraph
     related to stabilization, syndicate covering 

                                       18
<PAGE>
 
     transactions and penalty bids in any Preliminary Prospectus and the
     Prospectus constitute the only information furnished in writing by or on
     behalf of the several Underwriters for inclusion in any Preliminary
     Prospectus or the Prospectus.

          (c) Promptly after receipt by an indemnified party under this Section
     8 of notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against the indemnifying party
     under this Section 8, notify the indemnifying party in writing of the
     commencement thereof; but the failure so to notify the indemnifying party
     (i) will not relieve it from liability under paragraph (a) or (b) above
     unless and to the extent it did not otherwise learn of such action in a
     timely manner and such failure results in the forfeiture by the
     indemnifying party of substantial rights and defenses and (ii) will not, in
     any event, relieve the indemnifying party from any obligations to any
     indemnified party other than the indemnification obligation provided in
     paragraph (a) or (b) above.  The indemnifying party shall be entitled to
     appoint counsel of the indemnifying party's choice at the indemnifying
     party's expense to represent the indemnified party in any action for which
     indemnification is sought (in which case the indemnifying party shall not
     thereafter be responsible for the fees and expenses of any separate counsel
     retained by the indemnified party or parties except as set forth below);
     provided, however, that such counsel shall be reasonably satisfactory to
     --------  -------                                                       
     the indemnified party.  Notwithstanding the indemnifying party's election
     to appoint counsel to represent the indemnified party in an action, the
     indemnified party shall have the right to employ separate counsel
     (including local counsel), and the indemnifying party shall bear the
     reasonable fees, costs and expenses of such separate counsel if (i) the use
     of counsel chosen by the indemnifying party to represent the indemnified
     party would present such counsel with a conflict of interest, (ii) the
     actual or potential defendants in, or targets of, any such action include
     both the indemnified party and the indemnifying party and the indemnified
     party shall have reasonably concluded that there may be legal defenses
     available to it and/or other indemnified parties which are different from
     or additional to those available to the indemnifying party, (iii) the
     indemnifying party shall not have employed counsel reasonably satisfactory
     to the indemnified party to represent the indemnified party within a
     reasonable time after notice of the institution of such action or (iv) the
     indemnifying party shall authorize the indemnified party to employ separate
     counsel at the expense of the indemnifying party.  An indemnifying party
     will not, without the prior written consent of the indemnified parties,
     settle or compromise or consent to the entry of any judgment with respect
     to any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification or contribution may be sought hereunder (whether
     or not the indemnified parties are actual or potential parties to such
     claim or action) unless such settlement, compromise or consent includes an
     unconditional release of each indemnified party from all liability arising
     out of such claim, action, suit or proceeding.

          (d) In the event that the indemnity provided in paragraph (a) or (b)
     of this Section 8 is unavailable to or insufficient to hold harmless an
     indemnified party for any reason, the Company and the Underwriters agree to
     contribute to the aggregate losses, claims, damages and liabilities

                                       19
<PAGE>
 
     (including legal or other expenses reasonably incurred in connection with
     investigating or defending same) (collectively "Losses") to which the
     Company and one or more of the Underwriters may be subject in such
     proportion as is appropriate to reflect the relative benefits received by
     the Company on the one hand and by the Underwriters on the other from the
     offering of the Securities; provided, however, that in no case shall any
                                 --------  -------                           
     Underwriter (except as may be provided in any agreement among underwriters
     relating to the offering of the Securities) be responsible for any amount
     in excess of the underwriting discount or commission applicable to the
     Securities purchased by such Underwriter hereunder.  If the allocation
     provided by the immediately preceding sentence is unavailable for any
     reason, the Company and the Underwriters severally shall contribute in such
     proportion as is appropriate to reflect not only such relative benefits but
     also the relative fault of the Company on the one hand and of the
     Underwriters on the other in connection with the statements or omissions
     which resulted in such Losses as well as any other relevant equitable
     considerations.  Benefits received by the Company shall be deemed to be
     equal to the total net proceeds from the offering (before deducting
     expenses) received by it, and benefits received by the Underwriters shall
     be deemed to be equal to the total underwriting discounts and commissions,
     in each case as set forth on the cover page of the Prospectus.  Relative
     fault shall be determined by reference to, among other things, whether any
     untrue or any alleged untrue statement of a material fact or the omission
     or alleged omission to state a material fact relates to information
     provided by the Company on the one hand or the Underwriters on the other,
     the intent of the parties and their relative knowledge, access to
     information and opportunity to correct or prevent such untrue statement or
     omission.  The Company and the Underwriters agree that it would not be just
     and equitable if contribution were determined by pro rata allocation or any
     other method of allocation which does not take account of the equitable
     considerations referred to above.  Notwithstanding the provisions of this
     paragraph (d), no person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation.  For
     purposes of this Section 8, each person who controls an Underwriter within
     the meaning of either the Act or the Exchange Act and each director,
     officer, employee and agent of an Underwriter shall have the same rights to
     contribution as such Underwriter, and each person who controls the Company
     within the meaning of either the Act or the Exchange Act, each officer of
     the Company who shall have signed the Registration Statement and each
     director of the Company shall have the same rights to contribution as the
     Company, subject in each case to the applicable terms and conditions of
     this paragraph (d).

          9.   Default by an Underwriter.  If any one or more Underwriters shall
               -------------------------                                        
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder, and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the
aggregate principal amount of Securities set forth opposite the names of all the
remaining Underwriters) the Securities which the defaulting Underwriter or
Underwriters agreed but failed to purchase; provided, however, that in the event
                                            --------  -------                   

                                       20
<PAGE>
 
that the aggregate principal amount of Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of
the aggregate principal amount of Securities set forth in Schedule I hereto, the
remaining Underwriters shall have the right to purchase all, but shall not be
under any obligation to purchase any, of the Securities, and if such
nondefaulting Underwriters do not purchase all the Securities, this Agreement
will terminate without liability to any nondefaulting Underwriter or the
Company.  In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Prospectus or in any
other documents or arrangements may be effected.  Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the Company and any nondefaulting Underwriter for damages occasioned by its
default hereunder.

          10.  Termination.  This Agreement shall be subject to termination in
               -----------                                                    
the absolute discretion of the Representatives, by notice given to the Company
prior to delivery of and payment for the Securities, if at any time prior to
such time (i) trading in the Company's Common Stock shall have been suspended by
the Commission, the Pacific Stock Exchange or the New York Stock Exchange or
trading in securities generally on the Pacific Stock Exchange or the New York
Stock Exchange shall have been suspended or limited or minimum prices shall have
been established on such Exchange, (ii) a banking moratorium shall have been
declared either by Federal or New York State authorities or (iii) there shall
have occurred any outbreak or escalation of hostilities, declaration by the
United States of a national emergency or war or other calamity or crisis the
effect of which on financial markets is such as to make it, in the sole judgment
of the Representatives, impractical or inadvisable to proceed with the offering
or delivery of the Securities as contemplated by the Prospectus (exclusive of
any supplement thereto).

          11.  Representations and Indemnities to Survive.  The respective
               ------------------------------------------                 
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors or controlling persons referred to in Section 8 hereof,
and will survive delivery of and payment for the Securities.  The provisions of
Sections 7 and 8 hereof shall survive the termination or cancellation of this
Agreement.

          12.  Notices.  All communications hereunder will be in writing and
               -------

               ----------                                                     
binding upon the parties hereto and their respective successors and the officers

      Section 2.1.    Form and Dating.

              2.1.1.  General



          .  Attached hereto as Annex A-1 and Annex A-2, respectively, are true
and correct copies of specimen securities (each a "Form of Security")
representing the Company's _____% Senior Notes due 2008 (the "Series 1
Securities") and the Company's _____% Senior Notes due 2028 (the "Series 2
Securities," and collectively with the Series 1 Securities, the "Securities").
The Securities may have notations, legends or endorsements required by law,
stock exchange rule or usage.  Each Security shall be dated the date of its
authentication.  The Securities shall be in denominations of $1,000 and integral
multiples thereof.

          The terms and provisions contained in the Securities shall constitute,
and are hereby expressly made, a part of this Indenture, and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.  However, to the extent any
provision of any Security conflicts with the express 


                                      7
<PAGE>
 
provisions of this Indenture, the provisions of this Indenture shall govern and
be controlling.

          2.1.2.  Global Securities

          .  Securities issued in global form shall be substantially in the form
of the applicable Form of Security attached hereto (including the Global
Security Legend thereon and the "Schedule of Exchanges of Interests in the
Global Security" attached thereto).  Securities issued in definitive form shall
be substantially in the form of the applicable Form of Security attached hereto
(but without the Global Security Legend thereon and without the "Schedule of
Exchanges of Interests in the Global Security" attached thereto).  Each Global
Security shall represent such of the outstanding Securities as shall be
specified therein and each shall provide that it shall represent the aggregate
principal amount of outstanding Securities from time to time endorsed thereon
and that the aggregate principal amount of outstanding Securities represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions.  Any endorsement of a Global Security to
reflect the amount of any increase or decrease in the aggregate principal amount
of outstanding Securities represented thereby shall be made by the Trustee or
the Custodian, at the direction of the Trustee, in accordance with instructions
given by the Holder thereof as required by Section 2.6 hereof.

      Section 2.2.  Execution and Authentication.

          Two Officers shall sign the Securities for the Company by manual or
facsimile signature.  The Company's seal shall be reproduced on the Securities
and may be in facsimile form.

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

          A Security shall not be valid until authenticated by the manual
signature of the Trustee.  The signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

          The Trustee shall, upon a written order of the Company signed by two
Officers (an "Authentication Order"), authenticate Series 1 Securities and
Series 2 Securities for original issue up to the aggregate principal amount
stated in paragraph 1 of the applicable Form of Security.  The aggregate
principal amount of Series 1 Securities and Series 2 Securities outstanding at
any time may not exceed such amount except as provided in Section 2.7 hereof.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities.  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.  An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

      Section 2.3.  Registrar and Paying Agent.

          The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Securities may be presented for payment ("Paying Agent").
The Registrar shall keep a register of the Securities and of their transfer and
exchange.  The Company may appoint one or more co-registrars and one or more
additional paying agents.  The term "Registrar" includes any co-registrar and
the term "Paying Agent" includes any additional paying agent.  The Company may
change any Paying Agent or Registrar without notice to any Holder.  The Company
shall notify the Trustee in writing of the name and address of any Agent not a
party to this Indenture.  If the Company fails to appoint or maintain another
entity as Registrar or Paying Agent, the Trustee shall act as such.  The Company
or any of its Subsidiaries may act as Paying Agent or Registrar.

          The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Securities.

          The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Securities.

      Section 2.4.  Paying Agent to Hold Money in Trust.

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or interest on the Securities, and will notify the
Trustee of any default by the Company in making any such payment.  While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee.  The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee.  Upon payment over to the Trustee,
the Paying Agent (if other than the Company or a Subsidiary) shall have no
further liability for the money.  If the Company or a Subsidiary acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the benefit of
the Holders all money held by it as Paying Agent.  Upon any bankruptcy or
reorganization proceedings relating to the Company, the Trustee shall serve as
Paying Agent for the Securities.

      Section 2.5.  Holder 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
all Holders and shall otherwise comply with TIA (S) 312(a).  If the Trustee is
not the Registrar, the Company shall furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders, and
the Company shall otherwise comply with TIA (S) 312(a).

          .  A Global Security may not be transferred as a whole except by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary.  All Global Securities will be exchanged by the Company for
Definitive Securities if (i) the Company delivers to the Trustee notice from the
Depositary that it is unwilling or unable to continue to act as Depositary or
that it is no longer a clearing agency registered under the Exchange Act and, in
either case, a successor Depositary is not appointed by the Company within 120
days after the date of such notice from the Depositary or (ii) the Company in
its sole discretion determines that the Global Securities (in whole but not in
part) should be exchanged for Definitive Securities and delivers a written
notice to such effect to the Trustee.  Upon the occurrence of either of the
preceding events in (i) or (ii) above, Definitive Securities shall be issued in
such names as the Depositary shall instruct the Trustee. Global Securities also
may be exchanged or replaced, in whole or in part, as provided in Sections 2.7
and 2.10 hereof.  Every Security authenticated and delivered in exchange for, or
in lieu of, a Global Security or any portion thereof, pursuant to this Section
2.6 or Section 2.7 or 2.10 hereof, shall be authenticated and delivered in the
form of, and shall be, a Global Security.  A Global Security may not be
exchanged for another Security other than as provided in this Section 2.6.1,
however, beneficial interests in a Global Security may be transferred and
exchanged as provided in Section 2.6.2, 2.6.3 or 2.6.7 hereof.

          2.6.2.  Transfer and Exchange of Beneficial Interests in the Global
Securities

          .  The transfer and exchange of beneficial interests in the Global
Securities shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the applicable procedures.  Transfers of
beneficial interests in the Global Securities also shall require compliance with
either subparagraph (a) or (b) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

          (a) Transfer of Beneficial Interests in the Same Global Security

          .  Beneficial interests in any Global Security may be transferred to
Persons who take delivery thereof in the form of a beneficial interest in a
Global Security.  No written orders or instructions shall be required to be
delivered to the Registrar to effect the transfers described in this Section
2.6.2(a).

          (b) All Other Transfers and Exchanges of Beneficial Interests in
Global Securities

          .  In connection with all transfers and exchanges of beneficial
interests that are not subject to Section 2.6.2(a) above, the transferor of such
beneficial interest must deliver to the Registrar either (A) (1) a written order
from a Participant or an Indirect Participant given to the 


                                      10
<PAGE>
 
Depositary in accordance with the Applicable Procedures directing the Depositary
to credit or cause to be credited a beneficial interest in another Global
Security in an amount equal to the beneficial interest to be transferred or
exchanged and (2) instructions given in accordance with the Applicable
Procedures containing information regarding the Participant account to be
credited with such increase or (B) (1) a written order from a Participant or an
Indirect Participant given to the Depositary in accordance with the Applicable
Procedures directing the Depositary to cause to be issued a Definitive Security
in an amount equal to the beneficial interest to be transferred or exchanged and
(2) instructions given by the Depositary to the Registrar containing information
regarding the Person in whose name such Definitive Security shall be registered
to effect the transfer or exchange referred to in (1) above. Upon satisfaction
of all of the requirements for transfer or exchange of beneficial interests in
Global Securities contained in this Indenture and the Securities or otherwise
applicable under the Securities Act, the Trustee shall adjust the principal
amount of the relevant Global Security(s) pursuant to Section 2.6.7 hereof.

          2.6.3.  Transfer or Exchange of Beneficial Interests for Definitive
Securities

          .  If any holder of a beneficial interest in a Global Security
proposes to exchange such beneficial interest for a Definitive Security or to
transfer such beneficial interest to a Person who takes delivery thereof in the
form of a Definitive Security, then, upon satisfaction of the conditions set
forth in Section 2.6.2(b) hereof, the Trustee shall cause the aggregate
principal amount of the applicable Global Security to be reduced accordingly
pursuant to Section 2.6.8 hereof, and the Company shall execute and the Trustee
shall authenticate and deliver to the Person designated in the instructions a
Definitive Security in the appropriate principal amount. Any Definitive Security
issued in exchange for a beneficial interest pursuant to this Section 2.6.3
shall be registered in such name or names and in such authorized denomination or
denominations as the holder of such beneficial interest shall instruct the
Registrar through instructions from the Depositary and the Participant or
Indirect Participant.  The Trustee shall deliver such Definitive Securities to
the Persons in whose names such Securities are so registered.

          2.6.4.  Transfer and Exchange of Definitive Securities for Beneficial
Interests

          .  A Holder of a Definitive Security may exchange such Security for a
beneficial interest in a Global Security or transfer such Definitive Securities
to a Person who takes delivery thereof in the form of a beneficial interest in a
Global Security at any time.  Upon receipt of a request for such an exchange or
transfer, the Trustee shall cancel the applicable Definitive Security and
increase or cause to be increased the aggregate principal amount of one of the
Global Securities.

          2.6.5.  Transfer and Exchange of Definitive Securities for Definitive
Securities

          .  Upon request by a Holder of Definitive Securities and such Holder's
compliance with the provisions of this Section 2.6.5, the Registrar shall
register the transfer or exchange of Definitive Securities.  Prior to such
registration of transfer or exchange, the requesting Holder shall present or
surrender to the Registrar the Definitive Securities duly endorsed or
accompanied by a written instruction of transfer in form satisfactory to the
Registrar duly executed by such 


                                      11
<PAGE>
 
Holder or by its attorney, duly authorized in writing. In addition, the
requesting Holder shall provide any additional certifications, documents and
information, as applicable. A Holder of Definitive Securities may transfer such
Securities to a Person who takes delivery thereof in the form of a Definitive
Security.

          2.6.6.  Legends

          .  The following legends shall appear on the face of all Global
Securities issued under this Indenture unless specifically stated otherwise in
the applicable provisions of this Indenture.  Each Global Security shall bear a
legend in substantially the following form:

"THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITORY TRUST
COMPANY, A NEW YORK CORPORATION (THE "DEPOSITARY"), OR A NOMINEE THEREOF.  THIS
SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER
THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED
IN THE INDENTURE, AND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY
TO A NOMINEE OF THE DEPOSITARY, BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY

FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS
REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY (AND ANY PAYMENT IS MADE TO CEDE &
CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
THE DEPOSITARY), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER
HEREOF, CEDE & CO., HAS AN INTEREST HEREIN."

          2.6.7.  Cancellation and/or Adjustment of Global Securities

          .  At such time as all beneficial interests in a particular Global
Security have been exchanged for Definitive Securities or a particular Global
Security has been redeemed, repurchased or canceled in whole and not in part,
each such Global Security shall be returned to or retained and canceled by the
Trustee in accordance with Section 2.11 hereof.  At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for
or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Security or for Definitive Securities, the
principal amount of Securities represented by such Global Security shall be
reduced accordingly and an endorsement shall be 

                                      12
<PAGE>
 
made on such Global Security by the Trustee or by the Depositary at the
direction of the Trustee to reflect such reduction; and if the beneficial
interest is being exchanged for or transferred to a Person who will take
delivery thereof in the form of a beneficial interest in another Global
Security, such other Global Security shall be increased accordingly and an
endorsement shall be made on such Global Security by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

          2.6.8.   General Provisions Relating to Transfers and Exchanges.

          (a) To permit registrations of transfers and exchanges, the Company
     shall execute and the Trustee shall authenticate Global Securities and
     Definitive Securities upon the Company's order or at the Registrar's
     request.

          (b) No service charge shall be made to a holder of a beneficial
     interest in a Global Security or to a Holder of a Definitive Security for
     any registration of transfer or exchange, but the Company may require
     payment of a sum sufficient to cover any transfer tax or similar
     governmental charge payable in connection therewith (other than any such
     transfer taxes or similar governmental charge payable upon exchange or
     transfer pursuant to Sections 2.10, 3.6, 5.1 and 9.6 hereof).

          (c) The Registrar shall not be required to register the transfer or
     exchange of any Security selected for redemption in whole or in part,
     except the unredeemed portion of any Security being redeemed in part.

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

          (e) The Company shall not be required (A) to issue, to register the
     transfer of or to exchange any Securities during a period beginning at the
     opening of business 15 days before the day of any selection of Securities
     for redemption under Section 3.2 hereof and ending at the close of business
     on the day of selection, (B) to register the transfer of or to exchange any
     Security so selected for redemption in whole or in part, except the
     unredeemed portion of any Security being redeemed in part or (C) to
     register the transfer of or to exchange a Security between a record date
     and the next succeeding interest payment date.

          (f) Prior to due presentment for the registration of a transfer of any
     Security, the Trustee, any Agent and the Company may deem and treat the
     Person in whose name any Security is registered as the absolute owner of
     such Security for the purpose of receiving payment of principal of and
     interest on such Securities and for all other purposes, and none of the
     Trustee, any Agent or the Company shall be affected by notice to the
     contrary.

          (g) The Trustee shall authenticate Global Securities and Definitive
     Securities in 


                                      13
<PAGE>
 
accordance with the provisions of Section 2.2 hereof.

          (h) All certifications, certificates and Opinions of Counsel required
     to be submitted to the Registrar pursuant to this Section 2.6 to effect a
     registration of transfer or exchange may be submitted by facsimile.

      Section 2.7.  Replacement Securities.

          If any mutilated Security is surrendered to the Trustee or the Company
and the Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Security, the Company shall issue and the Trustee, upon receipt
of an Authentication Order, shall authenticate a replacement Security if the
Trustee's requirements are met.  If required by the Trustee or the Company, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Trustee and the Company to protect the Company, the Trustee, any Agent
and any authenticating agent from any loss that any of them may suffer if a
Security is replaced.  The Company may charge the Holder for its expenses in
replacing a Security.

          Every replacement Security is a valid obligation of the Company and
shall evidence the same debt as the Security for which it is a replacement.

      Section 2.8.  Outstanding Securities.

          The Securities outstanding at any time are all the Securities
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Security
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding.  Except as set forth in Section
2.9 hereof, a Security does not cease to be outstanding because the Company or
an Affiliate of the Company holds the Security.

          If a Security is replaced pursuant to Section 2.7 hereof, it ceases to
be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

          If the principal amount of any Security is considered paid under
Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to
accrue.

          If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Securities payable on that date, then on and after that date
such Securities shall be deemed to be no longer outstanding and shall cease to
accrue interest.

      Section 2.9.  Treasury Securities.

          In determining whether the Holders of the required principal amount of
Securities of either Series have concurred in any direction, waiver or consent,
Securities owned by the Company, 


                                      14
<PAGE>
 
or by any Affiliate of the Company, shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities of such Series that the Trustee knows are so owned shall be so
disregarded.

      Section 2.10. Temporary Securities.

          Until certificates representing Securities are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Securities.  Temporary Securities shall be
substantially in the form of certificated Securities but may have variations
that the Company considers appropriate for temporary Securities and as shall be
reasonably acceptable to the Trustee.  Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities in
exchange for temporary Securities.

          Holders of temporary Securities shall be entitled to all of the
benefits of this Indenture.

      Section 2.11. Cancellation.

          The Company at any time may deliver Securities to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment.  The Trustee and no one else shall cancel all Securities surrendered
for registration of transfer, exchange, payment, replacement or cancellation and
shall destroy canceled Securities (subject to the record retention requirement
of the Exchange Act). Certification of the destruction of all canceled
Securities shall be delivered to the Company.  The Company may not issue new
Securities to replace Securities that it has paid or that have been delivered to
the Trustee for cancellation.

      Section 2.12. Defaulted Interest.

          If the Company defaults in a payment of interest on the Securities of
either Series, it shall pay the defaulted interest in any lawful manner plus, to
the extent lawful, interest payable on the defaulted interest, to the Persons
who are Holders on a subsequent special record date, in each case at the rate
provided in such Securities and in Section 4.1 hereof.  The Company shall notify
the Trustee in writing of the amount of defaulted interest proposed to be paid
on each Security and the date of the proposed payment.  The Company  shall fix
or cause to be fixed each such special record date and payment date, provided
that no such special record date shall be less than 10 days prior to the related
payment date for such defaulted interest.  At least 15 days before the special
record date, the Company (or, upon the written request of the Company, the
Trustee in the name and at the expense of the Company) shall mail or cause to be
mailed to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

                                  REDEMPTION

      Section 3.1.  Notice to Trustee.

          The Company may, with respect to either Series of Securities, reserve
the right to redeem and pay the Series of Securities or may covenant to redeem
and pay the Series of Securities or any part thereof prior to the Stated
Maturity thereof at such time and on such terms as provided for in such
Securities.  If a Series of Securities is redeemable and the Company wants to
redeem prior to the Stated Maturity thereof all or part of the Series of
Securities pursuant to the terms of such Securities, it shall notify the Trustee
of the redemption date and the principal amount of the Series of Securities to
be redeemed.  The Company shall give the notice at least 45 days before the
redemption date (or such shorter notice as may be acceptable to the Trustee).

      Section 3.2.  Selection of Securities to be Redeemed.

          If less than all the Securities of a Series are to be redeemed at any
time, the Trustee shall select the Securities of the Series to be redeemed in
any manner that the Trustee deems fair and appropriate.  The Trustee shall make
the selection from Securities of the Series outstanding not previously called
for redemption.  The Trustee may select for redemption portions of the principal
of Securities of the Series that have denominations larger than $1,000.
Securities of the Series and portions of them it selects shall be in amounts of
$1,000 or whole multiples of $1,000. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption.

      Section 3.3.  Notice of Redemption.

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

          The notice shall identify the Securities of the Series to be redeemed
(including CUSIP numbers) and shall state:

          (a)  the redemption date;

          (b)  the redemption price;

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

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

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


                                      16
<PAGE>
 
          (f) any other information as may be required by the terms of the
     particular Series or the Securities being redeemed.

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense.

      Section 3.4.  Effect of Notice of Redemption.

          Once notice of redemption is mailed or published as provided in
Section 3.3, Securities called for redemption become due and payable on the
redemption date and at the redemption price.  A notice of redemption may not be
conditional.  Upon surrender to the Paying Agent, such Securities shall be paid
in accordance with the provisions provided for in the Securities.

      Section 3.5.  Deposit of Redemption Price.

          On or before 10:00 a.m., New York City time, on the redemption date,
the Company shall deposit with the Paying Agent money sufficient to pay the
redemption price of and accrued interest, if any, on all Securities to be
redeemed on that date.  The Trustee or the Paying Agent shall promptly return to
the Company any money deposited with the Trustee or the Paying Agent by the
Company in excess of the amounts necessary to pay the redemption price of, and
accrued interest on, all Securities to be redeemed.

          If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Securities or the portions of Securities called for redemption.  If a
Security is redeemed on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest shall be
paid to the Person in whose name such Security was registered at the close of
business on such record date.  If any Security called for redemption shall not
be so paid upon surrender for redemption because of the failure of the Company
to comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption date until such principal is paid, and to the
extent lawful on any interest not paid on such unpaid principal, in each case at
the rate provided in the Securities.

      Section 3.6.  Securities Redeemed in Part.

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

      Section 3.7.  Optional Redemption.

          The Securities of either Series will be redeemable, as a whole or in
part, at the option of the Company, pursuant to the terms contained in such
Securities.

                                   COVENANTS

      Section 4.1.  Payment of Principal and Interest.

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

      Section 4.2.  SEC Reports.

          The Company shall deliver to the Trustee, within 15 days after it
files them with the SEC, copies of the annual reports and of the information,
documents, and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) which the Company is required
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 (S) 314(a).

          Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

      Section 4.3.  Compliance Certificate.

          The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company, an Officers' Certificate stating that a
review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his knowledge the Company has kept, observed, performed and fulfilled each and
every covenant (without regard to periods of grace or notice requirements)
contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions hereof (or, if a
Default or Event of Default shall have occurred, describing all such Defaults or
Events of Default of which he may have knowledge).

          The Company will, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default
and what action the Company is taking or proposes to take with respect thereto.

      Section 4.4.  Stay, Extension and Usury Laws.

          The Company covenants (to the extent that it may lawfully do so) that
it will not at 


                                      18
<PAGE>
 
any time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay, extension or usury law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture or the Securities; and the Company (to the extent
it may lawfully do so) hereby expressly waives all benefit or advantage of any
such law and covenants that it will not, by resort to any such law, 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
has been enacted.

      Section 4.5.  Corporate Existence.

          Subject to Article V, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the corporate, partnership or other existence of each Significant
Subsidiary in accordance with the respective organizational documents of each
Significant Subsidiary and the rights (charter and statutory), licenses and
franchises of the Company and its Significant Subsidiaries; provided, however,
that the Company shall not be required to preserve any such right, license or
franchise, or the corporate, partnership or other existence of any Significant
Subsidiary, if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Subsidiaries taken as a whole and that the loss thereof is not adverse in
any material respect to the Holders.

      Section 4.6.  Taxes.

          The Company shall, and shall cause each of its Significant
Subsidiaries to, pay prior to delinquency all taxes, assessments and
governmental levies, except as contested in good faith and by appropriate
proceedings.

      Section 4.7.  Limitation on Secured Debt.

          The Company will not, and will not permit any Subsidiary to, create,
assume, or guarantee any Secured Debt without making effective provision for
securing the Securities equally and ratably with such Secured Debt.  The
foregoing restrictions shall not apply, however, to debt secured by (i) purchase
money mortgages created to secure payment for the acquisition or construction of
any property including, but not limited to, any indebtedness incurred by the
Company or a Subsidiary prior to, at the time of, or within 180 days after the
later of the acquisition, the completion of construction (including any
improvements on an existing property) or the commencement of commercial
operation of such property, which indebtedness is incurred for the purpose of
financing all or any part of the purchase price of such property or construction
or improvements on such property, (ii) mortgages, pledges, liens, security
interest or encumbrances (collectively referred to herein as "security
interests") on property, or any conditional sales agreement or any title
retention with respect to property, existing at the time of acquisition thereof,
whether or not assumed by the Company or a Subsidiary, (iii) security interests
on property or shares of capital stock or indebtedness of any corporation or
firm existing at the time such corporation or firm becomes a Subsidiary, (iv)
security interests in property or shares of capital stock or indebtedness of a
corporation existing at the time such corporation is 


                                      19
<PAGE>
 
merged into or consolidated with the Company or a Subsidiary or at the time of a
sale, lease, or other disposition of the properties of a corporation or firm as
an entirety or substantially as an entirety to the Company or a Subsidiary,
provided that no such security interests shall extend to any other Principal
Property of the Company or such Subsidiary prior to such acquisition or to other
Principal Property thereafter acquired other than additions or improvements to
the acquired property, (v) security interests on property of the Company or a
Subsidiary in favor of the United States of America or any state thereof, or in
favor of any other country, or any department, agency, instrumentality or
political subdivision thereof (including, without limitation, security interests
to secure indebtedness of the pollution control or industrial revenue type) in
order to permit the Company or any Subsidiary to perform a contract or to secure
indebtedness incurred for the purpose of financing all or any part of the
purchase price for the cost of constructing or improving the property subject to
such security interests or which is required by law or regulation as a condition
to the transaction of any business or the exercise of any privilege, franchise
or license, (vi) security interests on any property or assets of any Subsidiary
to secure indebtedness owing by it to the Company or to another Subsidiary,
(vii) any mechanics', materialmen's, carriers' or other similar lien arising in
the ordinary course of business (including construction of facilities) in
respect of obligations which are not yet due or which are being contested in
good faith, (viii) any security interest for taxes, assessments or government
charges or levies not yet delinquent, or already delinquent, but the validity of
which is being contested in good faith, (ix) any security interest arising in
connection with legal proceedings being contested in good faith, including any
judgment lien so long as execution thereof is being stayed, (x) landlords' liens
on fixtures located on premises leased by the Company or a Subsidiary in the
ordinary course of business, or (xi) any extension, renewal or replacement (or
successive extensions, renewals or replacements), in whole or in part, of any
security interest referred to in the foregoing clauses (i) to (x) inclusive.

      Section 4.8.  Limitation on Sale and Leaseback Transactions.

          The Company will not, and will not permit any Subsidiary to, enter any
lease for a term longer than three years (excluding leases of newly acquired,
improved or constructed property) covering any Principal Property of the Company
or any Subsidiary that is sold to any other person in connection with such lease
(a "Sale and Leaseback Transaction"), unless either (a) the Company or such
Subsidiary would be entitled, without equally and ratably securing the
Securities, to incur Indebtedness secured by a mortgage on the Principal
Property leased pursuant to clauses (i) through (xi) of Section 4.7 hereof, or
(b) an amount equal to the value of the Principal Property so leased is applied
to the retirement, within 120 days of the effective date of such arrangement, of
indebtedness for borrowed money incurred or assumed by the Company or a
Subsidiary which is recorded as Funded Debt as shown on the most recent
consolidated balance sheet of the Company and which in the case of such
Indebtedness of the Company, is not subordinate and junior in right of payment
to the prior payment of the Securities.

      Section 4.9.  Exempted Indebtedness.

          Notwithstanding Section 4.7 and Section 4.8, the Company and any one
or more 


                                      20
<PAGE>
 
Subsidiaries may, without securing the Securities, issue, assume, or guarantee
Secured Debt or enter into any Sale and Leaseback Transaction which would
otherwise be subject to the restrictions of Section 4.7 and Section 4.8,
provided that, after giving effect thereto, the aggregate amount of such Secured
Debt then outstanding (not including Secured Debt permitted under the exceptions
set forth in Section 4.7) and the Attributable Debt of Sale and Leaseback
Transactions (other than Sale and Leaseback Transactions in accordance with
clause (a) or (b) of Section 4.8) at such time does not exceed 15% of
Consolidated Net Assets.

transfer or lease all or substantially all of its assets to, another Person

any State or the District of Columbia, and such successor or transferee

supplemental indenture, (b) immediately after giving effect to the transaction,

the Company has delivered to the trustee an Officers' Certificate and an Opinion
of Counsel stating compliance with these provisions.

          Upon any consolidation or merger, or any sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company in
accordance with Section 5.1, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
lease, conveyance or other disposition is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor person has been named
as the Company herein; provided, however, that the predecessor Company in the
case of a sale, lease, conveyance or other disposition shall not be released
from the obligation to pay the principal of and interest, if any, on the
Securities.

                                  ARTICLE VI.

                             DEFAULTS AND REMEDIES

      Section 6.1.  Events of Default.

          "Event of Default," wherever used herein with respect to Securities of
either Series, means any one of the following events:

          (a) default in the payment of any interest on any Security of such
     Series when it becomes due and payable, and continuance of such default for
     a period of 30 days (unless 

                                      21

     the Holders of not less than 25% in principal amount of the outstanding
     Securities of such Series a written notice specifying such default or

      Section 6.2.  Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default with respect to Securities of either Series at
the time outstanding occurs and is continuing (other than an Event of Default
referred to in Section 6.1(d) or (e)), then in every such case the Trustee or
the Holders of not less than 25% in principal amount of the outstanding
Securities of that Series may declare the principal amount of and accrued and
unpaid interest, if any, on all of the Securities of that Series to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), and upon any such declaration such principal amount (or
specified amount) and accrued and unpaid interest, if any, shall become
immediately due and payable.  If an Event of Default specified in Section 6.1(d)
or (e) shall occur, the principal amount (or specified amount) of and accrued
and unpaid interest, if any, on all outstanding Securities shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder.

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

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

               (i)   all overdue interest, if any, on all Securities of that
          Series,

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

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

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

and

          (b) all Events of Default with respect to Securities of that Series,
     other than the non-payment of the principal of Securities of that Series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 6.13.

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


                                      23

      Section 6.3.  Collection of Indebtedness and Suits for Enforcement by
Trustee.

          The Company covenants that if

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

          (b) default is made in the payment of principal of any Security at the
     Maturity thereof,

then, the Company will, upon demand of the Trustee, pay to it, for the benefit
of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal or any
overdue interest, at the rate or rates prescribed therefor in such Securities,
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

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

      Section 6.4.  Trustee May File Proofs of Claim.

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

                                      24
<PAGE>
 
     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 of
     the Holders 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 in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.7.

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

      Section 6.5.  Trustee May Enforce Claims Without Possession of Securities.

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

      Section 6.6.  Application of Money Collected.

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

          First:    To the payment of all amounts due the Trustee under Section
7.7; and

          Second:   To the payment of the amounts then due and unpaid for
principal of and interest on the Securities in respect of which or for the
benefit of which such money has been collected, ratably, without preference or
priority of any kind (subject to any subordination provisions applicable to the
Securities of either Series), according to the amounts due and payable on such
Securities for principal and interest, respectively; and

          Third:    To the Company.

      Section 6.7.  Limitation on Suits.

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

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

          (b) the Holders of not less than 25% in principal amount of the
     outstanding Securities of that Series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

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

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

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

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

      Section 6.8.  Unconditional Right of Holders to Receive Principal and
Interest.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of, premium, if any, and interest, if any, on,
such Security on the Stated Maturity or Stated Maturities expressed in such
Security (or, in the case of redemption, on the redemption date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

      Section 6.9.  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all 

                                      26
<PAGE>
 
rights and remedies of the Trustee and the Holders shall continue as though no
such proceeding had been instituted.

      Section 6.10. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in Section 2.7, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

      Section 6.11. Delay or Omission Not Waiver.

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

      Section 6.12. Control by Holders.

          Subject to Section 7.1(e), the Holders of a majority in principal
amount of the outstanding Securities of either Series shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee, with respect to the Securities of such Series, provided that

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

          (b) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction, and

          (c) subject to the provisions of Section 6.1, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer of the Trustee, determine that the
     proceeding so directed would involve the Trustee in personal liability.

      Section 6.13. Waiver of Past Defaults.

          The Holders of not less than a majority in principal amount of the
outstanding Securities of either Series may on behalf of the Holders of all the
Securities of such Series waive any past Default hereunder with respect to such
Series and its consequences, except a Default in the payment of the principal
of, premium, if any, or interest, if any, on any Security of such Series or, 


                                      27
<PAGE>
 
if applicable, in respect of a covenant or provision which cannot be modified or
amended without the consent of the Holder of each outstanding Security of such
Series affected (provided, however, that the Holders of a majority in principal
amount of the outstanding Securities of either Series may rescind an
acceleration and its consequences, including any related payment default that
resulted from such acceleration). Upon any such waiver, such Default shall cease
to exist, and any Event of Default arising therefrom shall be deemed to have
been cured, for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other Default or impair any right consequent thereon.

      Section 6.14. Undertaking for Costs.

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

                                 ARTICLE VII.

                                    TRUSTEE

      Section 7.1.  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 their exercise as a prudent person
     would exercise or use under the circumstances in the conduct of his or her
     own affairs.

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

               (i) The Trustee need perform only those duties that are
          specifically set forth in this Indenture and no others.

               (ii) 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 Officers'
          Certificates or Opinions of Counsel furnished to the Trustee and
          conforming to the requirements of this Indenture; however, in the case
          of any 


                                      28
<PAGE>
 
          such Officers' Certificates or Opinions of Counsel which by any
          provisions hereof are specifically required to be furnished to the
          Trustee, the Trustee shall examine such Officers' Certificates and
          Opinions of Counsel to determine whether or not they conform to the
          requirements of this Indenture (but need not confirm or investigate
          the accuracy of mathematical calculations or other facts stated
          therein).

          (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:

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

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

               (iii)  The Trustee shall not be liable with respect to any action
          taken, suffered or omitted to be taken by it with respect to
          Securities of either Series in good faith in accordance with the
          direction of the Holders of a majority in principal amount of the
          outstanding Securities of such Series relating to the time, method and
          place of conducting any proceeding for any remedy available to the
          Trustee, or exercising any trust or power conferred upon the Trustee,
          under this Indenture with respect to the Securities of such Series.

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

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

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

          (g) No provision of this Indenture shall require the Trustee to risk
     its own funds or otherwise incur any financial liability in the performance
     of any of its duties, or in the exercise of any of its rights or powers, if
     it shall have reasonable grounds for believing that repayment of such funds
     or adequate indemnity against such risk is not reasonably assured to it.

          (h) The Paying Agent, the Registrar and any authenticating agent shall
     be entitled to the protections, immunities and standard of care as are set
     forth in paragraphs (a), (b) and (c) of this Section with respect to the
     Trustee.

      Section 7.2.  Rights of Trustee.

          (a) The Trustee may conclusively rely on and shall be protected in
     acting or refraining from acting upon 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.  No
     Depository shall be deemed an agent of the Trustee, and the Trustee shall
     not be responsible for any act or omission by any Depository.

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

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

          (g) The Trustee shall not be deemed to have notice of any Default or
     Event of Default unless a Responsible Officer of the Trustee has actual
     knowledge thereof or unless written notice of any event which is in fact
     such a default is received by the Trustee at the Corporate Trust Office of
     the Trustee, and such notice references the Securities and this Indenture.

      Section 7.3.  Individual Rights of Trustee.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate with the same rights it would have if it were not Trustee.  Any Agent
may do the same with like rights.  The Trustee is also subject to Sections 7.10
and 7.11.

      Section 7.4.  Trustee's Disclaimer.

          The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, and it shall not be responsible for any
statement in the Securities other than its authentication.

      Section 7.5.  Notice of Defaults.

          If a Default or Event of Default occurs and is continuing with respect
to the Securities of either Series and if it is known to a Responsible Officer
of the Trustee, the Trustee shall mail to each Securityholder of the Securities
of that Series, notice of a Default or Event of Default within 90 days after it
occurs or, if later, after a Responsible Officer of the Trustee has knowledge of
such Default or Event of Default.  Except in the case of a Default or Event of
Default in payment of principal of or interest on any Security of either Series,
the Trustee may withhold the notice if and so long as its corporate trust
committee or a committee of its Responsible Officers in good faith determines
that withholding the notice is in the interests of Securityholders of that
Series.

      Section 7.6.  Reports by Trustee to Holders.

          The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
TIA at the times and in the manner provided pursuant thereto.  If required by
Section 313(a) of the TIA, the Trustee shall, within sixty days after each April
1 following the date of this Indenture deliver to Holders a brief report, dated
as of April 1, which complies with the provisions of such Section 313(a).

          A copy of each report at the time of its mailing to Securityholders of
either Series shall be filed with the SEC and each stock exchange on which the
Securities of that Series are listed. The Company shall promptly notify the
Trustee when Securities of either Series are listed on any stock exchange or of
any delisting thereof.

      Section 7.7.  Compensation and Indemnity.

          The Company shall pay to the Trustee from time to time such
compensation for its services as shall be agreed in writing between the Company
and the Trustee.  The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust.  The Company shall reimburse the
Trustee upon request for all reasonable out-of-pocket expenses incurred by it.
Such expenses shall include the reasonable compensation and expenses of the
Trustee's agents and counsel.

          Except as set forth in the next paragraph, the Company shall indemnify
each of the Trustee and any predecessor Trustee against any and all loss,
damage, claim, liability or expense (including the cost of defending itself)
incurred by it in the acceptance or performance of its duties under this
Indenture as Trustee or Agent.  The Trustee shall notify the Company promptly of
any claim for which it may seek indemnity.  The Company shall defend the claim
and the Trustee shall 


                                      31
<PAGE>
 
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not
pay for any settlement made without its consent, which consent shall not be
unreasonably withheld. This indemnification shall apply to officers, directors,
employees, shareholders and agents of the Trustee.

          The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee or by any officer, director, employee,
shareholder or agent of the Trustee through negligence or bad faith.

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

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(d) or (e) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

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

      Section 7.8.  Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

          The Trustee may resign with respect to the Securities of either or
both Series by so notifying the Company.  The Holders of a majority in principal
amount of the Securities of either Series may remove the Trustee with respect to
that Series by so notifying the Trustee and the Company.  The Company may remove
the Trustee with respect to Securities of either or both Series if:

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

          (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
     relief is entered with respect to the Trustee under any Bankruptcy Law;

          (c) a Custodian or public officer takes charge of the Trustee or its
     property; or

          (d) the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee.  Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Securities of the
applicable Series may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.


                                      32
<PAGE>
 
          If a successor Trustee with respect to the Securities of either or
both Series does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company or the Holders of at
least 10% in principal amount of the Securities of the applicable Series may
petition, at the expense of the Company, any court of competent jurisdiction for
the appointment of a successor Trustee.

          If the Trustee with respect to the Securities of either or both Series
fails to comply with Section 7.10, any Securityholder of the applicable Series
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee subject to the lien provided for in Section 7.7, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
with respect to each Series of Securities for which it is acting as Trustee
under this Indenture.  A successor Trustee shall mail a notice of its succession
to each Securityholder of each such Series.  Notwithstanding replacement of the
Trustee pursuant to this Section 7.8, the Company's obligations under Section
7.7 hereof shall continue for the benefit of the retiring trustee with respect
to expenses and liabilities incurred by it prior to such replacement.

      Section 7.9.  Successor Trustee by Merger, etc.

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

      Section 7.10. Eligibility; Disqualification.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S) 310(a)(1), (2) and (5).  The Trustee shall always have a
combined capital and surplus of at least $25,000,000 as set forth in its most
recent published annual report of condition.  The Trustee shall comply with TIA
(S) 310(b).

      Section 7.11. Preferential Collection of Claims Against Company.

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

          than Securities that have been destroyed, lost or stolen and that have
          been replaced or paid) have been delivered to the Trustee for
          cancellation; or

               (ii) all such Securities not theretofore delivered to the Trustee
          for cancellation

             (1)  have become due and payable, or

     or

             (4) are deemed paid and discharged pursuant to Section 8.3, as
     applicable;

and the Company, in the case of (1), (2) or (3) above, has deposited or caused
to be deposited with the Trustee as trust funds in trust an amount sufficient
for the purpose of paying and discharging the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation, for

which have become due and payable on or prior to the date of such deposit) or to
the Stated Maturity or redemption date, as the case may be;

          (b) the Company has paid or caused to be paid all other sums payable

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.7, and, if money shall
have been deposited with the Trustee pursuant to clause (a) of this Section, the
provisions of Sections 2.3, 2.6, 2.7, 8.1, 8.2 and  8.5 shall survive.

      Section 8.2.  Application of Trust Funds; Indemnification.

          (a) Subject to the provisions of Section 8.5, all money deposited with
     the Trustee pursuant to Section 8.1, all money and U.S. Government
     Obligations deposited with the Trustee pursuant to Section 8.3 or 8.4 and

     Securities and this Indenture, to the payment, either directly or through
     any Paying Agent (including the Company acting as its own Paying Agent) as
     the Trustee may determine, to the persons entitled thereto, of the
     principal and interest for whose payment such money has been deposited with
     or received by the Trustee.

          (b) The Company shall pay and shall indemnify the Trustee against any
     tax, fee or other charge imposed on or assessed against U.S. Government
     Obligations deposited pursuant to Sections 8.3 or 8.4 or the interest and
     principal received in respect of such obligations other than any payable by
     or on behalf of Holders.

          (c) The Trustee shall deliver or pay to the Company from time to time
     upon Company Request any U.S. Government Obligations or money held by it as
     provided in Sections 8.3 or 8.4 which, in the opinion of a nationally
     recognized firm of independent certified public accountants expressed in a
     written certification thereof delivered to the Trustee, are then in excess
     of the amount thereof which then would have been required to be deposited
     for the purpose for which such U.S. Government Obligations or money were
     deposited or received.  This provision shall not authorize the sale by the
     Trustee of any U.S. Government Obligations held under this Indenture.

          The Company shall be deemed to have paid and discharged the entire
indebtedness on all the outstanding Securities of either Series on the 91st day
after the date of the deposit referred to in subparagraph (d) hereof, and the
provisions of this Indenture, as it relates to such outstanding Securities of
such Series, shall no longer be in effect (and the Trustee, at the expense of
the Company, shall, at Company Request, execute proper instruments acknowledging
the same), except as to:

          (a) the rights of Holders of Securities of such Series to receive,
     from the trust funds described in subparagraph (d) hereof, payment of the

     Company's obligations in connection therewith;

provided that, the following conditions shall have been satisfied:

          (d) the Company shall have deposited or caused to be deposited
     irrevocably with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for and
     dedicated solely to the benefit of the Holders of such Securities cash in
     Dollars (or such other money or currencies as shall then be legal tender in
     the United States) and/or U.S. Government Obligations, which through the
     payment of interest and principal in respect thereof, in accordance with
     their terms, will provide (and without reinvestment and assuming no tax
     liability will be imposed on such Trustee), not later than one day before
     the due date of any payment of money, an amount in cash, sufficient, in the
     opinion of a nationally recognized firm of independent public accountants
     expressed in a written certification thereof delivered to the Trustee, to
     pay and discharge each installment of principal of and interest, if any, on
     all the Securities of such Series on the dates such installments of
     interest or principal are due;

          (e) such deposit will not result in a breach or violation of, or

     or instrument to which the Company or any of its subsidiaries is a party or
     by which it is bound;

          (f) no Default or Event of Default with respect to the Securities of
     such Series shall have occurred and be continuing on the date of such
     deposit (other than a Default or Event of Default resulting from the
     borrowing of funds to be applied to such deposit) or insofar as Events of
     Default pursuant to Section 6.1(d) or Section 6.1(e) are concerned, during
     the period ending on the 91st day after such date;

          (g) the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect (i) that (A) the Company has received from, or there
     has been published by, the Internal Revenue Service a ruling, or (B) since
     the date of execution of this Indenture, there has been a change in the
     applicable Federal income tax law, in either case to the effect that, and
     based thereon such Opinion of Counsel shall confirm that, the Holders of
     the Securities of such Series will not recognize income, gain or loss for
     Federal income tax purposes as a result of such deposit, defeasance and
     discharge and will be subject to Federal income tax on the same amount and
     in the same manner and at the same times as would have been the case if
     such deposit, defeasance and discharge had not occurred and (ii) after the
     91st day following the date of the deposit, the trust funds will not be
     subject to the effect of any applicable Bankruptcy Laws;

          (h) the Company shall have delivered to the Trustee an Officers'
     Certificate 


                                      36

     preferring the Holders of the Securities of such Series over any other
     creditors of the Company or with the intent of defeating, hindering,
     delaying or defrauding any other creditors of the Company;

          (i) such deposit shall not result in the trust arising from such
     deposit constituting an investment company (as defined in the Investment
     Company Act of 1940, as amended), or such trust shall be qualified under
     such Act or exempt from regulation thereunder; and

or condition set forth under Sections 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, and 5.1
(and the failure to comply with any such covenants shall not constitute a
Default or Event of Default under Section 6.1)  with respect to the Securities
of such Series, provided that the following conditions shall have been
satisfied:

          (a) With reference to this Section 8.4, the Company has deposited or
     caused to be irrevocably deposited (except as provided in Section 8.2(c))
     with the Trustee as trust funds in trust, specifically pledged as security
     for, and dedicated solely to, the benefit of the Holders of such Securities
     cash in Dollars (or such other money or currencies as shall then be legal

     assuming no tax liability will be imposed on such Trustee), not later than
     one day before the due date of any payment of money, an amount in cash,
     sufficient, in the opinion of a nationally recognized firm of independent
     certified public accountants expressed in a written certification thereof
     delivered to the Trustee, to pay principal, premium, if any, and interest,
     if any, on the dates such installments of interest or principal are due;

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

          (c) No Default or Event of Default with respect to the Securities of
     such Series shall have occurred and be continuing on the date of such

     or loss for federal income tax purposes as a result of such deposit and

     delaying or defrauding any other creditors of the Company; and

          (f) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to the defeasance contemplated by

                             AMENDMENTS AND WAIVERS

     Section 9.1.  Without Consent of Holders.

          The Company and the Trustee may amend or supplement this Indenture or
the Securities of either or both Series without the consent of any
Securityholder:

          (a) to cure any ambiguity, defect or inconsistency;

          (b) to comply with Article V;

          (c) to make any change that would provide any additional rights or
     benefits to the Securityholders or does not adversely affect the rights of
     any Securityholder;

          (d) to provide for the issuance of and establish the form and terms
     and conditions of Securities of either or both Series as permitted by this
     Indenture;

          (e) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of either
     or both Series and to add to or change any of the provisions of this
     Indenture as shall be necessary to provide for or facilitate the
     administration of the trusts hereunder by more than one Trustee; or

                                      38
<PAGE>
 
          (f) to comply with requirements of the SEC in order to effect or
     maintain the qualification of this Indenture under the TIA.

     Section 9.2.  With Consent of Holders.

          The Company and the Trustee may enter into a supplemental indenture
with the written consent of the Holders of at least a majority in principal
amount of the outstanding Securities of each Series affected by such
supplemental indenture (including consents obtained in connection with a tender
offer or exchange offer for the Securities of such Series), for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the Securityholders of each such Series.  Except as
provided in Section 6.13, the Holders of at least a majority in principal amount
of the outstanding Securities of each Series affected by such waiver by notice
to the Trustee (including consents obtained in connection with a tender offer or
exchange offer for the Securities of such Series) may waive compliance by the
Company with any provision of this Indenture or the Securities with respect to
such Series.

          It shall not be necessary for the consent of the Holders of Securities
under this Section 9.2 to approve the particular form of any proposed
supplemental indenture or waiver, but it shall be sufficient if such consent
approves the substance thereof.  After a supplemental indenture or waiver under
this section becomes effective, the Company shall mail to the Holders of
Securities affected thereby a notice briefly describing the supplemental
indenture or waiver.  Any failure by the Company to mail or publish such notice,
or any defect therein, shall not, however, in any way impair or affect the
validity of any such supplemental indenture or waiver.

     Section 9.3.  Limitations.

          Without the consent of each Securityholder affected, an amendment or
waiver may not:

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

          (b) reduce the rate of or extend the time for payment of interest
     (including default interest) on any Security of such series;

          (c) reduce the principal on, or change the Stated Maturity of, any
     Security of such series ;

          (d) waive a Default or Event of Default in the payment of the
     principal of, or interest, if any, on, any Security of such series (except
     a rescission of acceleration of the Securities of either Series by the
     Holders of at least a majority in principal amount of the outstanding
     Securities of such Series and a waiver of the payment default that resulted
     from such acceleration);

                                      39
<PAGE>
 
          (e) make the principal of, or interest, if any, on, any Security
     payable in any currency other than that stated in the Security;

          (f) make any change in Sections 6.8, 6.13 or 9.3; or

          (g) waive a redemption payment with respect to any Security or change
     any of the provisions with respect to the redemption of any Securities.

     Section 9.4.  Compliance with Trust Indenture Act.

          Every amendment to this Indenture or the Securities of either or both
Series shall be set forth in a supplemental indenture hereto that complies with
the TIA as then in effect.

     Section 9.5.  Revocation and Effect of Consents.

          Until an amendment or waiver becomes effective, a consent to it by a
Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security.  However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment or waiver becomes effective.

          Any amendment or waiver once effective shall bind every Securityholder
of each Series affected by such amendment or waiver unless it is of the type
described in any of clauses (a) through (g) of Section 9.3.  In that case, the
amendment or waiver shall bind each Holder of a Security who has consented to it
and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security.

     Section 9.6.  Notation on or Exchange of Securities.

          The Trustee may place an appropriate notation about an amendment or
waiver on any Security of either Series thereafter authenticated.  The Company
in exchange for Securities of that Series may issue, and the Trustee shall
authenticate upon request, new Securities of that Series that reflect the
amendment or waiver.

     Section 9.7.  Trustee Protected.

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 7.1) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture.  The Trustee shall sign all
supplemental indentures, except that the Trustee need not sign any supplemental
indenture that adversely affects its rights.

twelve 30-day months) at the Treasury Rate (as defined below) plus ______ basis
points, plus, in the case of each of clause (i) and (ii) above, accrued interest
to the date of redemption.

Primary Treasury Dealer.

     "Remaining Scheduled Payments" means, with respect to each Security to be
redeemed, the remaining scheduled payments of the principal thereof and interest
thereon that would be due after the related redemption date but for such
redemption; provided, however, that if such redemption date 


     6

of computing Remaining Scheduled Payments, the amount of the next succeeding
scheduled interest payment thereon will be reduced by the amount of interest

annum equal to the semiannual equivalent yield to maturity (computed as of the

tender offer or exchange offer for the Securities), for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of the Indenture or of any supplemental indenture or of modifying in any manner
the rights of the Securityholders.  Subject to certain limitations described in
the Indenture, the Holders of at least a majority in principal amount of the
outstanding Securities by notice to the Trustee (including consents obtained in
connection with a tender offer or exchange offer for the Securities) may waive
compliance by the Company with any provision of the Indenture or the Securities.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

10.  Restrictive Covenants.

     The Indenture imposes certain limitations on the Company's and its
Subsidiaries' ability to create or incur certain Liens on certain of their
respective properties or assets and to enter into certain sale and lease-back
transactions and on the Company's ability to engage in mergers or consolidations
or the conveyance, transfer or lease of all or substantially all of its
properties and assets.  These limitations are subject to a number of important
qualifications and exceptions and reference is made to the Indenture for a
description thereof.

11.  Defaults and Remedies.

     If an Event of Default shall occur and be continuing, the principal of the
Securities may be declared (or, in certain cases, shall ipso facto become) due

<PAGE>
 
12.  Proceedings.

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

13.  Trustee Dealings with Company.

     The Trustee under the Indenture, in its individual or any other capacity,
may deal with the Company or an Affiliate of the Company with the same rights it
would have if it were not Trustee.

incorporator, as such, of the Company or any successor corporation shall not
have any liability for any obligations of the Company under this Security or the
Indenture or for any claim based on, in respect of, or by reason of such
obligations or their creation.  Each Securityholder by accepting a Security
waives and releases all such liability.  The waiver and release are part of the
consideration of issuance of the Securities.

Default with respect to the Securities and unless also the Holders of at least
25% in principal amount of the Securities at the time outstanding shall have
made written request, and offered reasonable indemnity, to the Trustee to
institute such proceedings as trustee, and the Trustee shall not have received
from the Holders of a majority in principal amount of Securities at the time
outstanding a direction inconsistent with such request, and shall have failed to
institute such proceeding, within 60 days. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any
payment of the principal hereof or any interest hereon on or after the
respective due dates expressed herein.

                    Letterhead of Wilmer, Cutler & Pickering

                               September 17, 1998
Danaher Corporation
1250 24th Street, N.W.
Washington, DC 20037

Ladies and Gentlemen:

     We have acted as counsel for Danaher Corporation, a Delaware corporation
(the "Issuer"), in connection with the Registration Statement on Form S-3 (the
"Registration Statement") being filed by the Issuer with the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Securities Act"), with respect to the debt securities of the
Issuer (the "Offered Securities").  The Offered Securities will be issued under
the indenture (the "Indenture"), between the Issuer and The First National Bank
of Chicago (the "Trustee"), as Trustee, filed as Exhibit 4 to the Registration
Statement.  The Offered Securities are to be sold pursuant to an underwriting
agreement (the "Underwriting Agreement") by and among the Issuer, Salomon Smith
Barney Inc., Chase Securities Inc., First Chicago Capital Markets, Inc. and
Lehman Brothers Inc., filed as Exhibit 1 to the Registration Statement.

     In connection with the foregoing, we have examined originals, or copies
certified or otherwise identified to our satisfaction, of such documents,
corporate records and other instruments as we have deemed necessary or
appropriate for the purposes of this opinion, including (a) the Certificate of
Incorporation, as amended, of the Issuer, (b) the By-laws, as amended, of the
Issuer, (c) the Indenture, (d) the Underwriting Agreement, (e) the form of the
Offered Securities and (f) the resolutions of the Board of Directors of the
Issuer authorizing the registration of the Offered Securities.

     In our examination of documents and records, we have assumed, without
investigation, the genuineness of all signatures, the legal capacity of natural
persons, the authenticity of all documents submitted to us as originals, the
conformity with originals of all documents submitted to us as telecopied,
certified, photostatic or reproduced copies and the authenticity of all such
documents. We have also assumed, but not independently verified, that all
documents executed by a party other than the Company or any respective
subsidiaries thereof were duly and validly authorized, executed and delivered by
such party, that such party has the requisite power and authority to execute,
deliver and perform such agreements and other documents, and that such
agreements and other documents are legal, valid and binding obligations of such
party and enforceable against such party in accordance with their respective
terms.
<PAGE>
 
     Based upon the foregoing and subject to the qualifications hereinafter set
forth, we are of opinion that:

     1.   The Offered Securities have been lawfully and duly authorized, and
such Offered Securities, upon execution and delivery of the Indenture by the
Issuer and the Trustee and upon issuance, execution and delivery of the Offered
Securities in accordance with the terms of the Indenture and the Underwriting
Agreement, and assuming due authentication by the Trustee, will be legal and
binding obligations of the Issuer enforceable against the Issuer in accordance
with their terms.

     This opinion set forth above in paragraph 1 is qualified to the extent we
have assumed the due execution and delivery of the Indenture by the Trustee
pursuant to appropriate corporate authority.

     Our opinion set forth above in paragraph 1 is subject to applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
other similar laws affecting creditors' rights generally from time to time in
effect.  The enforceability of the Issuer's obligations is also subject to
general principles of equity, including, without limitation, concepts of
materiality, reasonableness, good faith and fair dealing, regardless of whether
such enforceability is considered in a proceeding in equity or at law.

     This opinion is limited to the general corporate law of the State of
Delaware, and we express no opinion with respect to the applicability thereto,
or the effect thereon, of any other laws or as to any matters of municipal law
or the laws of any other local agencies within the state. We express no opinion
whatsoever as to any other laws or regulations or as to laws relating to choice
of law or conflicts of law principles.

     The information set forth herein is as of the date hereof. We assume no
obligation to advise you of changes which may thereafter be brought to our
attention. Our opinions are based on statutory and judicial decisions in effect
at the date hereof, and we do not opine with respect to any law, regulation,
rule or governmental policy or decision which may be enacted determined or
adopted after the date hereof, nor assume any responsibility to advise you of
future changes in our opinions.

     We are aware that we are referred to under the heading "Legal Matters" in
the prospectus forming a part of the Registration Statement, and we hereby
consent to such use of our name therein and the filing of this opinion as
Exhibit 5 to the Registration Statement.  In giving this consent, we do not
thereby admit that we are within the category of persons whose consent is
required under Section 7 of the Securities Act or the Rules and Regulations of
the Commission promulgated thereunder.

                                    Very truly yours,

                                    /s/  Meredith B. Cross
