                           DESCRIPTION OF DEBENTURES
 
     The following description of the particular terms of the Debentures offered
hereby (referred to herein as the "Debentures" and in the Prospectus as the
"Debt Securities") supplements, and to the extent inconsistent therewith,
replaces, the description of the general terms and provisions of the Debt
Securities set forth in the Prospectus, to which description reference is hereby
made. The following summary of the Debentures is qualified in its entirety by
reference to the Indenture referred to in the Prospectus.
 
GENERAL
 
     The Debentures will be limited to $100,000,000 in aggregate principal
amount. The Debentures will be issued in denominations of $1,000 and integral
multiples of $1,000, will bear interest from July 15, 1997 at the annual rate
set forth on the cover page of this Prospectus Supplement, and will mature on
July 15, 2027. Interest will be payable semi-annually on January 15 and July 15,
commencing January 15, 1998 to the holders of record of the Debentures on the
preceding January 1 and July 1, respectively. The Debentures will be issued in
book-entry form. See "Description of Debt Securities -- Registered Global
Securities" in the Prospectus.
 
     The Debentures will not be subject to a sinking fund.
 
OPTIONAL REDEMPTION
 
     The Debentures will be redeemable as a whole or in part, at the option of
the Company at any time at a redemption price equal to the greater of (i) 100%
of the principal amount of such Debentures and (ii) the sum of the present
values of the remaining scheduled payments of principal and interest thereon
discounted to the redemption date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Treasury Rate as defined below, plus
15 basis points, plus in each case accrued interest thereon to the date of
redemption.
 
     "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.
 
                                       S-2
<PAGE>   3
 
     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Debentures to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such Debentures. "Independent Investment Banker" means one of
the Reference Treasury Dealers appointed by the Company.
 
     "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such business day, (A) the average
of the Reference Treasury Dealer Quotations for such redemption date, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(B) if the Company obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Quotations. "Reference Treasury Dealer
Quotations" means, with respect to each Reference Treasury Dealer and any
redemption date, the average, as determined by the Company, of the bid and asked
prices for the Comparable Treasury Issue (expressed in each case as a percentage
of its principal amount) quoted in writing to the Company by such Reference
Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption
date.
 
     "Reference Treasury Dealer" means each of Chase Securities Inc. and
Citicorp Securities, Inc. and their respective successors and, at the option of
the Company, additional Primary Treasury Dealers; provided, however, that if any
of the foregoing shall cease to be a primary U.S. Government securities dealer
in New York City (a "Primary Treasury Dealer"), the Company shall substitute
therefor another Primary Treasury Dealer.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Debentures to be redeemed.
 
     Unless the Company defaults in payment of the redemption price, on and
after the redemption date interest will cease to accrue on the Debentures or
portions thereof called for redemption.
 
BOOK-ENTRY SYSTEMS
 
     The Debentures will be issued in fully registered form in the name of Cede
& Co., as nominee of DTC. One or more fully registered certificates will be
issued as Global Securities for the Debentures in the aggregate principal amount
of the Debentures. Such Global Securities will be deposited with DTC and may not
be transferred except as a whole by DTC to a nominee of DTC or by a nominee of
DTC to DTC or another nominee of DTC or by DTC or any nominee to a successor of
DTC or a nominee of such successor.
 
     DTC has advised the Company and the Underwriters as follows:
 
          DTC is a limited-purpose trust company organized under the New York
     Banking Law, a "banking organization" under the New York Banking Law, a
     member of the Federal Reserve System, a "clearing corporation" within the
     meaning of the New York Uniform Commercial Code, and a "clearing agency"
     registered pursuant to the provisions of Section 17A of the Securities
     Exchange Act of 1934, as amended. DTC holds securities that its
     participants ("Participants") deposit with DTC. DTC also facilitates the
     settlement among Participants of securities transactions, such as transfers
     and pledges, in deposited securities, through electronic computerized
     book-entry changes in Participants' accounts, thereby eliminating the need
     for physical movement of securities certificates. Direct Participants
     include securities brokers and dealers, banks, trust companies, clearing
     corporations, and certain other organizations. DTC is owned by a number of
     its Direct Participants and by the New York Stock Exchange, Inc.,
 
                                       S-3
<PAGE>   4
 
     the American Stock Exchange, Inc. and the National Association of
     Securities Dealers, Inc. Access to the DTC system is also available to
     others such as securities brokers and dealers, banks, and trust companies
     that clear through or maintain a custodial relationship with a Direct
     Participant, either directly or indirectly ("Indirect Participants"). The
     rules applicable to DTC and its Participants are on file with the
     Securities and Exchange Commission.
 
          Purchases of Debentures under the DTC system must be made by or
     through Direct Participants, which will receive a credit for the Debentures
     on DTC's records. The ownership of interest of each actual purchaser of
     Debentures ("Beneficial Owner") is in turn to be recorded on the Direct and
     Indirect Participants' records. Beneficial Owners will not receive written
     confirmation from DTC of their purchase, but Beneficial Owners are expected
     to receive written confirmations providing details of the transaction, as
     well as periodic statements of their holdings, from the Direct and Indirect
     Participant through which the Beneficial Owner entered into the
     transaction. Transfers of ownership interests in the Debentures are to be
     accomplished by entries made on the books of Participants acting on behalf
     of Beneficial Owners. Beneficial Owners will not receive certificates
     representing their ownership interests in the Debentures, except in the
     event that use of the book-entry system for the Debentures is discontinued.
 
          To facilitate subsequent transfers, all Debentures deposited by
     Participants with DTC are registered in the name of DTC's partnership
     nominee, Cede & Co. The deposit of Debentures with DTC and their
     registration in the name of Cede & Co. effect no change in beneficial
     ownership. DTC has no knowledge of the actual Beneficial Owners of the
     Debentures; DTC's records reflect only the identity of the Direct
     Participants to whose accounts such Debentures are credited, which may or
     may not be the Beneficial Owners. The Participants will remain responsible
     for keeping account of their holdings on behalf of their customers.
 
          Conveyance of notices and other communications by DTC to Direct
     Participants, by Direct Participants to Indirect Participants, and by
     Direct Participants and Indirect Participants to Beneficial Owners will be
     governed by arrangements among them, subject to any statutory or regulatory
     requirements as may be in effect from time to time.
 
          Redemption notices shall be sent to DTC. If less than all of the
     Global Securities within an issue are being redeemed, DTC's practice is to
     determine by lot the amount of the interest of each Direct Participant in
     such issue to be redeemed.
 
          Neither DTC nor Cede & Co. will consent or vote with respect to the
     Global Securities. Under its usual procedures DTC mails an Omnibus Proxy to
     Issuer as soon as possible after the record date. The Omnibus Proxy assigns
     Cede & Co.'s consenting or voting rights to those Direct Participants to
     whose accounts the Securities are credited on the record date (identified
     in the listing attached to the Omnibus Proxy).
 
     Principal and interest payments on the Global Securities will be made to
DTC. The Company expects that DTC, upon receipt of any payment of principal or
interest in respect of a Global Security, will credit immediately Participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Security as shown on DTC's
records. The Company also expects that payments by Participants to Beneficial
Owners will be governed by standing instructions and customary practices, as is
the case with securities held for the accounts of customers in bearer form or
registered in "street name", and will be the responsibility of such Participant
and not of DTC, the Company or the Trustee, subject to any statutory or
regulatory requirements as may be in effect from time to time.
 
     DTC may discontinue providing its service as securities depositary with
respect to the Debentures at any time by giving reasonable notice to the Company
or the Trustee. In addition, the Company may decide to discontinue use of the
system of book-entry transfers through DTC (or a successor securities
depositary). Under such circumstances, if a successor securities depositary is
 
                                       S-4
<PAGE>   5
 
not obtained, Debenture certificates in fully registered form are required to be
printed and delivered to Beneficial Owners of the Global Securities representing
such Debentures.
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Company believes to be reliable
(including DTC), but the Company takes no responsibility for the accuracy
thereof.
 
     Neither the Company, the Trustee nor the Underwriters will have any
responsibility or obligation to Participants, or the persons for whom they act
as nominees, with respect to the accuracy of the records of DTC, its nominee or
any Participant with respect to any ownership interest in the Debentures, or
payments to, or the providing of notice to Participants or Beneficial Owners.
 
     The Debentures will trade in DTC's Same-Day Funds Settlement System and
secondary market trading activity in the Debentures will, therefore, settle in
immediately available funds. All applicable payments of principal and interest
on the Debentures issued as Global Securities will be made by the Company in
immediately available funds.
 
     For other terms of the Debentures, see "Description of Debt Securities" in
the accompanying Prospectus.
 
DEFEASANCE
 
     The Debentures will be subject to defeasance and discharge and to
defeasance of certain obligations as described under "Description of
Securities -- Defeasance" in the Prospectus.
 
                                  UNDERWRITING
 
     Subject to the terms and conditions set forth in the Underwriting Agreement
(the "Underwriting Agreement"), dated July 9, 1997 among the Company and the
several Underwriters named below (the "Underwriters"), the Company has agreed to
sell to the Underwriters and the Underwriters have severally agreed to purchase
from the Company, the following respective principal amounts of Debentures:

</TABLE>
 
     In the Underwriting Agreement, the Underwriters have agreed, subject to the
terms and conditions set forth therein, to purchase all of the Debentures
offered hereby if any of the Debentures are purchased.
 
     The Company has been advised by the Underwriters that the Underwriters
propose to offer the Debentures to the public initially at the respective
offering price set forth on the cover page of this Prospectus Supplement, and to
certain dealers initially at such price less a discount not in excess of .50% of
the principal amount of the Debentures. The Underwriters may allow, and such
dealers may reallow, a concession to certain other dealers not in excess of .25%
of the principal amount. After the public offering, the public offering price
and such concessions may be changed.
 
     The Underwriters and their affiliates have in the past and may in the
future provide investment banking, general financing and banking or other
services to the Company and its affiliates.
 
     The Company has agreed to indemnify the Underwriters against certain civil
liabilities, including liabilities under the Securities Act of 1933, as amended,
and to contribute to payments which the Underwriters might be required to make
in respect thereof.
 
                                       S-5
<PAGE>   6
 
     In connection with the offering and sale of the Debentures, Chase
Securities Inc., on behalf of the Underwriters, may engage in overallotment,
stabilizing transactions and syndicate covering transactions in accordance with
Regulation M under the Exchange Act. Overallotment involves sales in excess of
the offering size, which creates a short position for the Underwriters.
Stabilizing transactions permit bids to purchase the Debentures in the open
market for the purpose of pegging, fixing or maintaining the price of the
Debentures. Syndicate covering transactions involve purchases of the Debentures
in the open market after the distribution has been completed in order to cover
short positions. Such stabilizing transactions and syndicate covering
transactions may cause the price of the Debentures to be higher than it would
otherwise be in the absence of such transactions. Such activities, if commenced,
may be discontinued at any time.
 
     The Debentures are a new series of securities with no established trading
market. The Underwriters have advised the Company that they intend to make a
market in the Debentures, but are under no obligation to do so and such market
making may be terminated at any time without notice. Therefore, no assurance can
be given as to the liquidity of, or the trading market for, the Debentures.
 
     It is expected that delivery of the Debentures will be made against payment
therefor on or about the date specified in the last paragraph of the cover page
of this Prospectus Supplement, which is the fourth business day following the
date hereof. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as
amended, trades in the secondary market generally are required to settle in
three business days, unless the parties to any such trade expressly agree
otherwise. Accordingly, purchasers who wish to trade the Debentures on the date
hereof or any day prior to the third business day before the date of delivery of
the Debentures will be required, by virtue of the fact that the Debentures will
settle in T+4, to agree to a delayed settlement cycle at the time of any such
trade to prevent a failed settlement. Those who purchase the Debentures and wish
to trade Debentures on the date hereof or the next succeeding business day
should consult their own advisor.
 
                                 LEGAL MATTERS
 
     Certain legal matters in connection with the Debentures will be passed upon
for the Company by William G. von Glahn, Senior Vice President and General
Counsel of Williams, and for the Underwriters by Davis Polk & Wardwell, New
York, New York. Mr. von Glahn beneficially owns approximately 28,331 shares of
Williams' Common Stock and also has exercisable options to purchase an
additional 29,260 shares of Williams' Common Stock. Pursuant to its By-laws and
an indemnity agreement, Williams is required to indemnify Mr. von Glahn to the
fullest extent permitted by Delaware law against any expenses actually and
reasonably incurred by him in connection with any action, suit or proceeding in
which he is made party by reason of his being an officer of Williams. Williams
also maintains directors' and officers' liability insurance under which Mr. von
Glahn is insured against certain expenses and liabilities.

"Plan of Distribution" for possible indemnification arrangements for dealers,
underwriters, and agents.

                                  THE COMPANY
 
     The Company is an interstate natural gas transmission company that owns and
operates a natural gas pipeline system originating in the Louisiana Gulf Coast
area and in East Texas and running generally north and east through Louisiana,
Arkansas, Mississippi, Tennessee, Kentucky, and Indiana and into Ohio, with
smaller diameter lines extending into Illinois. The Company's direct market area
encompasses eight states in the South and Midwest and includes the Memphis,
Tennessee; Louisville, Kentucky; Cincinnati and Dayton, Ohio; and Indianapolis,
Indiana, metropolitan areas. The Company also has indirect market access to the
Northeast through interconnections with unaffiliated pipelines. The Company's
transmission activities are subject to regulation by the Federal Energy
Regulatory Commission ("FERC") under the Natural Gas Act of 1938 and under the
Natural Gas Policy Act of 1978.
 
     The Company was formerly a wholly owned, indirect subsidiary of Transco
Energy Company, which The Williams Companies, Inc. ("Williams") acquired on
January 18, 1995. Following the acquisition, direct ownership of the Company was
transferred to Williams.
 
     The Company was incorporated in Delaware in 1945. The Company's principal
executive offices are located at 3800 Frederica Street, Owensboro, Kentucky
42301 (telephone: (502) 926-8686).
 
                                USE OF PROCEEDS
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the net
proceeds from the sale of the Debt Securities will be used for general corporate
purposes, including repayment of outstanding debt. The Company anticipates that
it may raise additional funds from time to time through debt financings,
including sale of additional Debt Securities.

estimated to represent an interest factor for the Company.
 
                            SELECTED FINANCIAL DATA
 
     The following income statement, balance sheet, and cash flow data for the
quarter ended March 31, 1997, have been derived from the Company's unaudited,
consolidated financial statements included in the Company's Quarterly Report on
Form 10-Q for the quarter ended March 31, 1997, incorporated herein by
reference. The income statement and cash flow data for the years 1994 through
1996 and the balance sheet data for 1995 and 1996 have been derived from the
Company's audited financial statements included in the Company's Annual Report
on Form 10-K for the year ended December 31, 1996, incorporated herein by
reference. The income statement and cash flow data for 1993 and 1992 and the

from audited financial statements of the Company previously filed with the
Commission but not incorporated by reference. The acquisition of Transco Energy
Company and its subsidiaries, including the Company, by Williams was accounted
for by using the purchase method of accounting. Accordingly, the purchase price
was "pushed down" and included in the following selected data beginning January
18, 1995, which affects the comparability of the post-acquisition and pre-
acquisition financial data. The selected financial data should be read in
conjunction with such financial statements, the notes thereto, and the related
management's narrative analysis of the results of operations.

PIPELINE SYSTEM AND CUSTOMERS
 
     The Company's natural gas pipeline system, having a mainline delivery
capacity of approximately 2.8 billion cubic feet (Bcf) of gas per day, is
composed of approximately 6,000 miles of mainline and branch transmission
pipelines and 32 compressor stations having a sea-level-rated capacity totaling
approximately 549,000 horsepower. The Company owns and operates natural gas
storage reservoirs in 10 underground storage fields located on or near its
pipeline system and/or market areas.
 
     The Company transports natural gas to customers in Louisiana, Arkansas,
Mississippi, Tennessee, Kentucky, Indiana, Illinois, and Ohio and to customers
in the Northeast served indirectly by the Company. The Company transports gas
for approximately 133 distribution companies and municipalities for resale to
residential, commercial, and industrial users and provides transportation
services to approximately 102 industrial customers located along the system. The
Company has transportation contracts with approximately 559 shippers.
Transportation shippers include distribution companies, municipalities,
intrastate pipelines, direct industrial users, electrical generators, marketers,
and producers. In 1996, the Company did not have any customer accounting for
more than ten percent of total operating revenues. The Company's firm
transportation agreements are generally long-term agreements with various
expiration dates and account for the major portion of the Company's business.
Additionally, the Company offers interruptible transportation and storage
services under agreements that are generally short term.

(iv) interest rate or rates (or method by which such rate will be determined),
if any; (v) the dates on which any such interest will be payable; (vi) the place
or places where the principal of and interest, if any, on the Offered Debt
Securities will be payable; (vii) any redemption or sinking fund provisions;
(viii) whether the Offered Debt Securities will be issuable in registered or
bearer form or both and, if Offered Debt Securities in bearer form are issuable,
restrictions applicable to the exchange of one form for another and to the
offer, sale, and delivery of Offered Debt Securities in bearer form; (ix) any
applicable United States federal income tax consequences, including whether and
under what circumstances the Company will pay additional amounts on Offered Debt
Securities held by a Person who is not a United States Person (as defined in the
Prospectus Supplement) in respect of any tax, assessment, or governmental charge
withheld or deducted, and if so, whether the Company will have the option to
redeem such Debt Securities rather than pay such additional amounts; and (x) any
other specific terms of the Offered Debt Securities, including any additional
events of default or covenants provided for with respect to such Debt
Securities, and any terms that may be required by or advisable under United
States laws or regulations.
 
     Debt Securities may be presented for exchange, and registered Debt
Securities may be presented for transfer in the manner, at the places, and
subject to the restrictions set forth in the Debt Securities and the Prospectus
Supplement. Such services will be provided without charge, other than any tax or
other governmental charge payable in connection therewith, but subject to the
limitations provided in the applicable Indenture. Debt Securities in bearer form
and the coupons, if any, appertaining thereto will be transferable by delivery.
 
     Debt Securities that bear interest will do so at a fixed rate or a floating
rate. Debt Securities bearing no interest or interest at a rate that at the time
of issuance is below the prevailing market rate will be sold at a discount below
their stated principal amount. Special United States federal income tax
considerations applicable to any such discounted Debt Securities or to certain
Debt Securities issued at par that are treated as having been issued at a
discount for United States federal income tax purposes will be described in the
relevant Prospectus Supplement.
 
REGISTERED GLOBAL SECURITIES
 
     The registered Debt Securities of a series may be issued in the form of one
or more fully registered global Securities (a "Registered Global Security") that
will be deposited with a depositary (the "Depositary") or with a nominee for a
Depositary identified in the Prospectus Supplement relating to such series. In
such case, one or more Registered Global Securities will be issued in a
denomination or aggregate denominations equal to the portion of the aggregate
principal amount of outstanding registered Debt Securities of the series to be
represented by such Registered Global Security or Securities. Unless and until
it is exchanged in whole or in part for Debt Securities in definitive registered
form, a Registered Global Security may not be transferred except as a whole by
the Depositary for such Registered Global Security to a nominee of such
Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor of such Depositary or a nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to any
portion of a series of Debt Securities to be represented by a Registered Global
Security will be described in the Prospectus Supplement relating to such series.
The Company anticipates that the following provisions will apply to all
depositary arrangements.
 
     Upon the issuance of a Registered Global Security, the Depositary for such
Registered Global Security will credit, on its book-entry registration and
transfer system, the respective principal amounts of the Debt Securities
represented by such Registered Global Security to the accounts of Persons that
have accounts with such Depositary ("participants"). The accounts to be credited
shall be designated by any underwriters or agents participating in the
distribution of such Debt Securities. Ownership of beneficial interests in a
Registered Global Security will be limited to participants or Persons that may
hold interests through participants. Ownership of beneficial interests in such
Registered Global Security will be shown on, and the transfer of that ownership
will be effected only through, records maintained by the Depositary for such
Registered Global Security (with respect to interests of participants) or by
participants or Persons that hold
 
                                        7
<PAGE>   14
 
through participants (with respect to interests of Persons other than
participants). So long as the Depositary for a Registered Global Security, or
its nominee, is the registered owner of such Registered Global Security, such
Depositary or such nominee, as the case may be, will be considered the sole
owner or Holder of the Debt Securities represented by such Registered Global
Security for all purposes under the Indenture. Except as set forth below, owners
of beneficial interests in a Registered Global Security will not be entitled to
have the Debt Securities represented by such Registered Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of such Debt Securities in definitive form and will not be considered
the owners or Holders thereof under the Indenture.
 
     Principal, premium, if any, and interest payments on Debt Securities
represented by a Registered Global Security registered in the name of a
Depositary or its nominee will be made to such Depositary or its nominee, as the
case may be, as the registered owner of such Registered Global Security. None of
the Company, the Trustee, or any paying agent for such Debt Securities will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in such Registered
Global Security or for maintaining, supervising, or reviewing any records
relating to such beneficial ownership interests.
 
     The Company expects that the Depositary for any Debt Securities represented
by a Registered Global Security, upon receipt of any payment of principal,
premium, or interest, will immediately credit participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of such Registered Global Security as shown on the records
of such Depositary. The Company also expects that payments by participants to
owners of beneficial interests in such Registered Global Security held through
such participants will be governed by standing instructions and customary
practices, as is now the case with the securities held for the accounts of
customers registered in "street names" and will be the responsibility of such
participants.
 
     If the Depositary for any Debt Securities represented by a Registered
Global Security is at any time unwilling or unable to continue as Depositary and
a successor Depositary is not appointed by the Company within ninety days, the
Company will issue such Debt Securities in definitive form in exchange for such
Registered Global Security. In addition, the Company may at any time and in its
sole discretion determine not to have any of the Debt Securities of a series
represented by one or more Registered Global Securities and, in such event, will
issue Debt Securities of such series in definitive form in exchange for all of
the Registered Global Security or Securities representing such Debt Securities.
 
CERTAIN COVENANTS OF THE COMPANY
 
     Limitation on Liens. The Indenture provides that, subject to certain
exceptions, the Company will not, nor will it permit any Subsidiary to, issue,
assume, or guarantee any Indebtedness secured by a mortgage, pledge, lien,
security interest, or encumbrance ("mortgage") of, or upon any property of the
Company or any Subsidiary without effectively providing that the Debt Securities
issued thereunder shall be equally and ratably secured with such Indebtedness.
Among the exceptions are purchase money mortgages; preexisting mortgages on any
property acquired by the Company or a Subsidiary and mortgages on any property
acquired or constructed by the Company or a Subsidiary and created within one
year after completion of such acquisition or construction; mortgages created on
any contract for the sale of products or services related to the operation or
use of any property acquired or constructed within one year after completion of
such acquisition or construction; mortgages on property of a Subsidiary existing
at the time it became a Subsidiary of the Company or existing on property at the
time of acquisition thereof; and other mortgages not permitted by clauses (a) -
(y) of Section 3.6 therein in an aggregate amount which, at the time of
incurrence and together with the Attributable Debt in respect of sale and
lease-back transactions permitted by paragraph (a) of Section 3.7, does not
exceed five percent of Consolidated Net Tangible Assets. (Section 3.6)
 
     Limitation on Sale and Lease-Back Transactions. The Indenture provides that
the Company will not, nor will it permit any Subsidiary to, sell and lease back
for more than three years any Principal Property acquired or placed into service
more than 180 days before such lease arrangement, unless (a) the lessee would be
entitled to incur Indebtedness secured by a mortgage on such Principal Property
in a principal amount
 
                                        8
<PAGE>   15
 
equivalent to the Attributable Debt in respect of such arrangement without
equally and ratably securing the Debt Securities issued thereunder or (b) the
Company retires Funded Indebtedness or causes Funded Indebtedness to be retired
within 90 days of the effective date of such sale and lease-back transaction
equal to the net proceeds of such sale. This limitation does not apply to sale
and lease-back transactions (i) relating to industrial development or pollution
control financing or (ii) involving only the Company and any Subsidiary or
Subsidiaries, nor are such transactions included in any computation of
Attributable Debt. Notwithstanding the foregoing, the Company and its
Subsidiaries may enter into sale and lease-back transactions so long as the
total consolidated Attributable Debt in respect of such transactions does not
exceed five percent of Consolidated Net Tangible Assets. (Section 3.7)
 
     Consolidation, Merger, Conveyance of Assets. The Indenture provides, in
general, that the Company will not consolidate with or merge into any other
corporation or convey, transfer, or lease its properties and assets
substantially as an entirety to any Person, unless the corporation formed by
such consolidation or into which the Company is merged or the Person that
acquires such assets shall expressly assume the Company's obligations under the
Indenture and the Debt Securities issued thereunder and immediately after giving
effect to such transaction, no Event of Default, and no event which, after
notice or lapse of time or both, would become an Event of Default, shall have
happened and be continuing. (Section 8.1)
 
     Event Risk. Except for the limitations on Liens and Sale and Leaseback
Transactions described above, the Indenture and Debt Securities do not contain
any covenants or other provisions designed to afford holders of the Debt
Securities protection in the event of a highly leveraged transaction involving
the Company.
 
EVENTS OF DEFAULT
 
     In general, an Event of Default is defined under the Indenture with respect
to Debt Securities of any series issued under the Indenture as being: (a)
default in payment of any principal of the Debt Securities of such series,
either at maturity, upon any redemption, by declaration, or otherwise; (b)
default for 30 days in payment of any interest on any Debt Securities of such
series unless otherwise provided; (c) default for 90 days after written notice
in the observance or performance of any covenant or warranty in the Debt
Securities of such series (other than a covenant a default in whose performance,
or whose breach, is dealt with otherwise below); provided, however, that the
occurrence of any of the events described in this clause (c) shall not
constitute an Event of Default if such occurrence is the result of changes in
generally accepted accounting principles; or (d) certain events of bankruptcy,
insolvency, or reorganization of the Company. (Section 4.1)
 
     In general, the Indenture provides that, (a) if an Event of Default
described in clauses (a), (b) or (c) above (if the Event of Default under clause
(c) is with respect to less than all series of Debt Securities then outstanding)
occurs, either the Trustee or the Holders of not less than 25 percent in
principal amount of the Debt Securities of each affected series (voting as one
class) issued under the Indenture and then outstanding may then declare the
entire principal of all Debt Securities of each such affected series and
interest accrued thereon to be due and payable immediately and (b) if an Event
of Default due to a default described in clause (c) above which is applicable to
all series of Debt Securities then outstanding or due to certain events of
bankruptcy, insolvency, and reorganization of the Company shall have occurred
and be continuing, the Trustee or the Holders of not less than 25 percent in
principal amount of all Debt Securities issued under the Indenture and then
outstanding (voting as one class) may declare the entire principal of all such
Debt Securities and interest accrued thereon to be due and payable immediately,
but upon certain conditions such declarations may be annulled and past defaults
may be waived (except a continuing default in payment of principal of, premium,
if any, or interest on such Debt Securities) by the Holders of a majority in
aggregate principal amount of the Debt Securities of all such affected series
then outstanding (voting as one class). (Sections 4.1 and 4.10)
 
     The Indenture contains a provision entitling the Trustee, subject to the
duty of the Trustee during a default to act with the required standard of care,
to be indemnified by the Holders of Debt Securities (treated as one class)
issued under the Indenture before proceeding, at the request of such Holders, to
exercise any right or power under the Indenture. (Section 5.2) Subject to such
provisions in the Indenture for the indemnification of the Trustee and certain
other limitations, the Holders of a majority in aggregate principal
 
                                        9
<PAGE>   16
 
amount of the outstanding Debt Securities of each series affected (voting as one
class) issued under the Indenture may 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. (Section 4.9)
 
     In general, the Indenture provides that no Holder of Debt Securities issued
under the Indenture may institute any action against the Company under the
Indenture (except actions for payment of principal or interest on or after the
due date provided) unless such Holder previously shall have given to the Trustee
written notice of default and continuance thereof and unless the Holders of not
less than 25 percent in principal amount of the Debt Securities of each affected
series (treated as one class) issued under the Indenture and then outstanding
shall have requested the Trustee to institute such action and shall have offered
the Trustee reasonable indemnity and the Trustee shall not have instituted such
action within 60 days of such request and the Trustee shall not have received
direction inconsistent with such written request by the Holders of a majority in
principal amount of the Debt Securities of each affected series (treated as one
class) issued under the Indenture and then outstanding. (Sections 4.6, 4.7, and
4.9)
 
     The Indenture contains a covenant that the Company will file annually with
the Trustee a certificate of no default or a certificate specifying any default
that exists. (Section 3.5)
 
DISCHARGE, DEFEASANCE, AND COVENANT DEFEASANCE
 
     The Company can discharge or defease its obligations under the Indenture as
set forth below. (Section 9.1)
 
     Under terms satisfactory to the Trustee, the Company may discharge certain
obligations to Holders of any series of Debt Securities issued under the
Indenture which have not already been delivered to the Trustee for cancellation
and which have either become due and payable or are by their terms due and
payable within one year (or scheduled for redemption within one year) by
irrevocably depositing with the Trustee cash or, in the case of Debt Securities
payable only in United States dollars, United States Government Obligations (as
defined in the Indenture) as trust funds in an amount certified to be sufficient
to pay at maturity (or upon redemption) the principal of and interest on such
Debt Securities.
 
     The Company may also, upon satisfaction of the conditions listed below,
discharge certain obligations to Holders of any series of Debt Securities issued
under the Indenture at any time ("defeasance"). Under terms satisfactory to the
Trustee, the Company may instead be released with respect to any outstanding
series of Debt Securities issued under the Indenture from the obligations
imposed by Sections 3.6, 3.7, and 8.1, (which contain the covenants described
above limiting liens, sale and lease-back transactions, consolidations, mergers,
and conveyances of assets), and omit to comply with such Sections without
creating an Event of Default ("covenant defeasance"). Defeasance or covenant
defeasance may be effected only if, among other things: (i) the Company
irrevocably deposits with the Trustee cash or, in the case of Debt Securities
payable only in United States dollars, United States Government Obligations, as
trust funds in an amount certified to be sufficient to pay at maturity (or upon
redemption) the principal of and interest on all outstanding Debt Securities of
such series issued under such Indenture; and (ii) the Company delivers to the
Trustee an opinion of counsel to the effect that the Holders of such series of
Debt Securities will not recognize income, gain, or loss for United States
federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to United States federal income tax on the same
amounts, in the same manner, and at the same times as would have been the case
if defeasance or covenant defeasance had not occurred (in the case of a
defeasance, such opinion must be based on a ruling of the United States Internal
Revenue Service or a change in United States federal income tax law occurring
after the date of the Indenture, since such a result would not occur under
current tax law).
 
MODIFICATION OF THE INDENTURE
 
     The Indenture provides that the Company and the Trustee may enter into
supplemental indentures (which conform to the provisions of the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act of 1939")) without the consent
of the Holders to, in general: (a) secure any Debt Securities; (b) evidence the
assumption by a successor Person of the obligations of the Company; (c) add
further covenants for the
 
                                       10
<PAGE>   17
 
protection of the Holders; (d) cure any ambiguity or correct any inconsistency
in the Indenture, so long as such action will not adversely affect the interests
of the Holders; (e) establish the form or terms of Debt Securities of any
series; and (f) evidence the acceptance of appointment by a successor trustee.
(Section 7.1)
 
     The Indenture also contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than the majority in
principal amount of Debt Securities of all series issued under the Indenture
then outstanding and affected (voting as one class) to, in general, add any
provisions to, or change in any manner or eliminate any of the provisions of,
the Indenture or modify in any manner the rights of the Holders of the Debt
Securities of each series so affected; provided that such changes conform to
provisions of the Trust Indenture Act of 1939 and provided that the Company and
the Trustee may not, without the consent of each Holder of outstanding Debt
Securities affected thereby, (a) extend the final maturity of the principal of
any Debt Securities, or reduce the principal amount thereof or reduce the rate
or extend the time of payment of interest thereon, or reduce any amount payable
on redemption thereof or change the currency in which the principal thereof
(including any amount in respect of original issue discount) or interest thereon
is payable, or reduce the amount of any original issue discount security payable
upon acceleration or provable in bankruptcy or alter certain provisions of the
Indenture relating to Debt Securities not denominated in U.S. dollars or for
which conversion to another currency is required to satisfy the judgment of any
court, or impair the right to institute suit for the enforcement of any payment
on any Debt Securities when due or (b) reduce the aforesaid percentage in
principal amount of Debt Securities of any series issued under such Indenture,
the consent of the Holders of which is required for any such modification.
(Section 7.2)
 
CONCERNING THE TRUSTEE
 
     The Trustee is one of a number of banks with which the Company and its
affiliates maintain ordinary banking relationships and with which the Company
and its affiliates maintain credit facilities.
 
               LIMITATIONS ON ISSUANCE OF BEARER DEBT SECURITIES
 
     Except as may otherwise be provided in the Prospectus Supplement applicable
thereto, in compliance with United States federal income tax laws and
regulations, Bearer Debt Securities (including Bearer Debt Securities in global
form) will not be offered, sold, resold or delivered, directly or indirectly, in
the United States or its possessions or to United States persons (as defined
below), except as permitted by United States Treasury Regulations Section
1.163-5(c)(2)(i)(D). Any underwriters, agents and dealers participating in the
offerings of Bearer Debt Securities, directly or indirectly, must agree that (i)
they will not, in connection with the original issuance of any Bearer Debt
Securities or during the restricted period, as defined in United States Treasury
Regulations Section 1.163-5(c)(2)(i)(D)(7) (the "restricted period"), offer,
sell, resell or deliver, directly or indirectly, any Bearer Debt Securities in
the United States or its possessions or to United States persons (other than as
permitted by the applicable Treasury Regulations described above). In addition,
any such underwriters, agents and dealers must have procedures reasonably
designed to ensure that its employees or agents who are directly engaged in
selling Bearer Debt Securities are aware of the above restrictions on the
offering, sale, resale or delivery of Bearer Debt Securities. Moreover, Bearer
Debt Securities (other than temporary global Debt Securities and Bearer Debt
Securities that satisfy the requirements of United States Treasury Regulations
Section 1.163-5(c)(2)(i)(D)(3)(ii)) and any coupons appertaining thereto will
not be delivered in definitive form nor will any interest be paid on any Bearer
Debt Securities, unless the Company has received a signed certificate in writing
(or an electronic certificate described in United States Treasury Regulations
Section 1.163-5(c)(2)(i)(D)(3)(iii) stating that on such date such Bearer Debt
Security (i) is owned by a person that is not a United States person, (ii) is
owned by a United States person that (a) is a foreign branch of a United States
financial institution (as defined in United States Treasury Regulations Section
1.165-12(c)(1)(v)) (a "financial institution") purchasing for its own account or
for resale, or (b) is acquiring such Bearer Debt Securities through a foreign
branch of a United States financial institution and who holds the Bearer Debt
Security through such financial institution through such date (and in either
case (a) or (b), each such United States financial institution agrees, on its
own behalf or through its agent, that the Company may be advised that it will
comply with the requirements of Section 165(j)(3)(A), (B), or (C) of the United
States Internal Revenue Code, and the regulations thereunder) or (iii) is owned
by a United
 
                                       11
<PAGE>   18
 
States or foreign financial institution for the purposes of resale during the
restricted period and such financial institution certifies that it has not
acquired the Bearer Debt Security for purposes of resale directly or indirectly
to a United States person or to a person within the United States or its
possessions.
 
     Bearer Securities (other than temporary global Debt Securities) and any
Coupons appertaining thereto will bear a legend substantially to the following
effect: "Any United States person who holds this obligation will be subject to
limitations under the United States federal income tax laws, including the
limitations provided in Sections 165(j) and 1287(a) of the United States
Internal Revenue Code." The sections referred to in such legend provide that a
United States person (other than a United States financial institution described
above or United States person holding through such a financial institution) who
holds a Bearer Security or coupon will not be allowed to deduct any loss
realized on the sale, exchange, or redemption of such Bearer Security and will
not be eligible for capital gain treatment with respect to any gain recognized
on such sale, exchange, or redemption.
 
     As used herein, "United States person" means any person who is, for United
States federal income tax purposes, a citizen, national, or resident of the
United States, a corporation, partnership, or other entity created or organized
in or under the laws of the United States or any political subdivision thereof,
or an estate or trust the income of which is subject to United States federal
income taxation regardless of its source.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Offered Debt Securities in the following ways: (i)
through agents; (ii) through underwriters; (iii) through dealers; and (iv)
directly to purchasers.
 
     Offers to purchase the Offered Debt Securities may be solicited by agents
designated by the Company from time to time. Any such agent, who may be deemed
to be an underwriter as that term is defined in the Securities Act, involved in
the offer or sale of the Offered Debt Securities in respect of which this
Prospectus is delivered will be named, and any commissions payable by the
Company to such agent set forth, in the Prospectus Supplement. Unless otherwise
indicated in the Prospectus Supplement, any such agent will be acting on a best
efforts basis for the period of its appointment.
 
     If any underwriters are utilized in the sale, the Company will enter into
an underwriting agreement with such underwriters at the time of sale to them and
the names of the underwriters and the terms of the transaction will be set forth
in the Prospectus Supplement, which will be used by the underwriters to make
resales to the public of the Offered Debt Securities in respect of which this
Prospectus is delivered.
 
     If a dealer is utilized in the sale of the Offered Debt Securities in
respect of which this Prospectus is delivered, the Company will sell such
Offered Debt Securities to the dealer, as principal. The dealer may then resell
such Offered Debt Securities to the public at varying prices to be determined by
such dealer at the time of resale.
 
     Agents, dealers, and underwriters may be entitled under agreements entered
into with the Company to indemnification by the Company against certain civil
liabilities, including liabilities under the Securities Act, or to contribution
with respect to payments which such agents, dealers, or underwriters may be
required to make in respect thereof. Agents, dealers, and underwriters may be
customers of, engage in transactions with, or perform services for the Company
in the ordinary course of business.
 
     The Offered Debt Securities may also be offered and sold, if so indicated
in the Prospectus Supplement, in connection with a remarketing upon their
purchase, in accordance with a redemption or repayment pursuant to their terms,
or otherwise, by one or more firms ("remarketing firms"), acting as principals
for their own accounts or as agents for the Company. Any remarketing firm will
be identified and the terms of its agreement, if any, with the Company and its
compensation will be described in the Prospectus Supplement. Remarketing firms
may be deemed to be underwriters in connection with the Offered Debt Securities
remarketed thereby. Remarketing firms may be entitled under agreements which may
be entered into with the Company to indemnification by the Company against
certain civil liabilities, including liabilities under the Securities Act,
 
                                       12
<PAGE>   19
 
and may be customers of, engage in transactions with or perform services for the
Company in the ordinary course of business.
 
     If so indicated in the Prospectus Supplement, the Company will authorize
agents and underwriters or dealers to solicit offers by certain purchasers to
purchase the Offered Debt Securities from the Company at the public offering
price set forth in the Prospectus Supplement pursuant to delayed delivery
contracts providing for payment and delivery on a specified date in the future.
Such contracts will be subject to only those conditions set forth in the
Prospectus Supplement, and the Prospectus Supplement will set forth the
commission payable for solicitation of such offers.
