ITEM 1. BUSINESS
 
                                    GENERAL
 
     In 1987, Tenneco Inc. was incorporated in Delaware and acquired all of the
outstanding shares of TGP. In the Merger discussed below (i) the name Tenneco
Inc. was changed to EPTPC and (ii) EPTPC became an indirect subsidiary of EPG.
EPTPC is a holding company. The major businesses of the Company consist of the
interstate transportation of natural gas, which generally is subject to
regulation by the FERC, as well as certain other non-regulated business
operations, such as gas marketing, intrastate pipeline operations, international
pipelines and power generation operations and domestic power generation
operations. Prior to the Distributions and Merger described below, the Company
also was engaged in the manufacture and sale of automotive exhaust system parts
and ride control products; the manufacture and sale of packaging materials,
cartons, containers and specialty packaging products for consumer and commercial
markets; and the construction and repair of ships.
 
                               ACQUISITION BY EPG
 
     On December 12, 1996, an indirect subsidiary of EPG merged into Old Tenneco
(the "Merger"), resulting in Old Tenneco becoming an indirect subsidiary of EPG.
The Merger was effected in accordance with the Amended and Restated Agreement
and Plan of Merger dated as of June 19, 1996
(the "Merger Agreement"). In the Merger, Old Tenneco changed its name to EPTPC.
Prior to the Merger, Old Tenneco and its subsidiaries effected various
intercompany transfers and distributions which restructured, divided and
separated their businesses, assets and liabilities so that all the assets,
liabilities and operations related to their automotive parts, packaging and
administrative services businesses (collectively, the "Industrial Business") and
their shipbuilding business (the "Shipbuilding Business") were spun-off to Old
Tenneco's then existing common stockholders (the "Distributions"). The entity
consisting of the Industrial Business was subsequently renamed Tenneco Inc.
("New Tenneco") and the entity consisting of the Shipbuilding Business was
subsequently renamed Newport News Shipbuilding Inc. ("Newport News"). Following
the Distributions, the remaining operations of the Company consisted primarily
of those operations related to the transmission and marketing of natural gas and
the discontinued operations of Old Tenneco. In preparation for the Merger and
Distributions, Old Tenneco initiated a realignment of the Company's indebtedness
(the "Debt Realignment"). As part of the Debt Realignment, Old Tenneco initiated
tender offers for certain issues of debt of Old Tenneco and certain of its
subsidiaries and certain other debt issues which were exchanged into New Tenneco
debt, defeased, or otherwise retired. Upon completion of the Debt Realignment
transactions, the Company is only responsible for its remaining debt which was
not tendered, exchanged, defeased or otherwise retired. As a result of the
Merger, EPG owns 100 percent of the common stock of EPTPC, representing at the
effective time of the Merger approximately 75 percent of the equity value of
EPTPC; the balance of the equity value of EPTPC is held by the holders of its
Series A Preferred Stock which was issued in a registered public offering in
November 1996 and remains outstanding. For a further discussion, see Note 1 of
Item 8, Financial Statements and Supplementary Data.
 
                              REGULATED OPERATIONS
 
     The regulated operations of the Company include the interstate pipeline
systems of TGP, Midwestern and East Tennessee, as well as certain joint
ventures, which are primarily engaged in the transportation and storage of
natural gas for producers, marketers, end-users and other gas transmission and
distribution companies. TGP's multiple-line system begins in the gas-producing
regions of Texas and Louisiana, including the continental shelf of the Gulf of
Mexico, and extends into the northeastern section of the U.S., including the New
York City and Boston metropolitan areas. Midwestern's pipeline system extends
from Portland, Tennessee, to Chicago, and principally serves the Chicago
metropolitan area. East Tennessee's pipeline system serves the states of
Tennessee, Virginia and Georgia and connects with TGP's pipeline system in
Springfield and Lobelville, Tennessee. Net revenues from the interstate gas
sales and transportation operations of the
 
                                        1
<PAGE>   5
 
Company accounted for approximately 32 percent, 40 percent, and 39 percent of
total revenues of the Company for 1996, 1995, and 1994, respectively.
 
     The interstate gas transmission systems of the Company include
approximately 16,300 miles of pipeline, gathering lines and sales laterals (with
14,800 miles operated by TGP, 400 miles operated by Midwestern and 1,100 miles
operated by East Tennessee), together with related facilities that include 90
compressor stations with an aggregate of approximately 1.5 million horsepower.
The Company also has interests in or contractual rights to six underground and
above-ground gas storage facilities to permit increased deliveries of gas during
peak demand periods. The total design delivery capacity of the Company's
interstate systems as of December 31, 1996, was approximately 4,900 MMcf/d,
giving effect for deliveries into Midwestern and East Tennessee, and
approximately 5,800 MMcf/d at peak demand, giving effect for gas withdrawn from
storage.
 
     The following table sets forth the volumes of gas sold and transported by
the interstate pipeline systems of EPTPC for the periods shown.

* Sales and transportation volumes include all natural gas sold or transported
  by the Company's interstate pipeline systems (including the proportionate
  share of transportation volumes of the joint ventures in which the Company had
  interests) and have not been adjusted to reflect the sale of (i) a 50 percent
  interest in Kern River in December 1995, and (ii) a 13.2 percent general
  partnership interest in Iroquois in June 1996. Kern River owns a 904-mile
  pipeline system extending from Wyoming to California. Iroquois owns a 370-mile
  pipeline extending from the Canadian border at Waddington, New York, to Long
  Island, New York. Of the total transportation volumes shown, Kern River
  transported approximately 136 MMdth and 130 MMdth during 1995 and 1994,
  respectively. Iroquois transported approximately 20 MMdth, 45 MMdth and 32
  MMdth during 1996, 1995 and 1994, respectively.
 
  Regulatory Environment
 
     The Company's interstate system is subject to the jurisdiction of FERC in
accordance with the Natural Gas Act of 1938 and the Natural Gas Policy Act of
1978.
 
     In the mid-1980s, FERC began a series of actions which ultimately had the
effect of substantially removing interstate pipelines from the gas purchase and
resale business and confining their role to transportation of gas owned by
others. In Order No. 436, issued in 1985, FERC began this transition by
requiring interstate pipelines to provide non-discriminatory access to their
facilities for all transporters of natural gas. This requirement enabled
consumers to purchase their own gas and have it transported on the interstate
pipeline system, rather than purchase gas from the pipelines. The transition was
completed with Order No. 636, issued in 1992, in which FERC required all
interstate pipelines to "unbundle" their sales and transportation services so
that the transportation services they provided to third parties would be
"comparable" to the transportation services accorded to gas owned by the
pipelines. FERC's stated purpose was to ensure that the pipelines' monopoly over
the transportation of natural gas did not distort the gas producer sales market,
which had by then been essentially deregulated.
 
     One of the obstacles to this transition was the existence of long-term gas
purchase contracts between pipelines and producers which required the pipelines
to take or pay for a significant percentage of the gas which the producer was
capable of delivering. While FERC did not deal with this issue initially, it
eventually adopted rate recovery procedures which facilitated negotiations
between pipelines and producers to address take-or-pay issues. In Order No. 636,
FERC provided that pipelines could recover 100 percent of the costs prudently
incurred to terminate their gas purchase obligations. In July 1996, the Court of
Appeals issued its decision upholding, in large part, Order No. 636, and
remanded to FERC several issues for further
 
                                        2
<PAGE>   6
 
explanation, including further explanation of FERC's decision to allow pipelines
to recover 100 percent of GSR costs and FERC's requirement that pipelines
allocate 10 percent of GSR costs to interruptible transportation customers. In
February 1997, FERC reaffirmed its decision to allow pipelines to recover 100
percent of GSR costs. In addition, FERC modified the requirement that pipelines
allocate 10 percent of GSR costs to interruptible customers to permit pipelines
to propose an allocation of any percentage of such costs to their interruptible
customers. For a further discussion of GSR issues related to TGP, see Item 3,
Legal Proceedings, Item 7, Management's Discussion and Analysis of Financial
Condition and Results of Operations, and Note 5 of Item 8, Financial Statements
and Supplementary Data.
 
     In December 1994, TGP filed for a general rate increase (the "1995 Rate
Case"). In January 1995, FERC accepted the filing, suspended its effectiveness
for the maximum period of five months pursuant to normal regulatory process, and
set the matter for hearing. On July 1, 1995, TGP began collecting rates, subject
to refund, reflecting an $87 million increase in TGP's annual revenue
requirement. A Stipulation and Agreement (the "Stipulation") was filed with an
ALJ in this proceeding in April 1996. The Stipulation resolves the rates that
are the subject of the 1995 Rate Case, including a structural rate design change
that results in a larger proportion of TGP's transportation revenues being
dependent upon throughput. Under the Stipulation, TGP is required to refund,
upon final approval of the Stipulation, the difference between the revenues
collected under the July 1, 1995 motion rates and the revenues that would have
been collected pursuant to the rates underlying the Stipulation. In October
1996, FERC approved the Stipulation with certain modifications and
clarifications which are not material. In January 1997, FERC issued an order
denying requests for rehearing of the October 1996 order. One party to the rate
proceeding, a competitor of TGP, filed with the Court of Appeals in February
1997, a Petition for Review of the FERC orders approving the Stipulation.
 
     For a discussion of recent FERC proceedings relating to the recovery by TGP
of certain environmental costs as a component of the rates charged by its
interstate pipeline operations, see Note 5 of Item 8, Financial Statements and
Supplementary Data.
 
  Markets and Competition
 
     The Company's interstate pipeline operations face varying degrees of
competition from alternative energy sources, such as electricity, coal, and oil.
The potential consequences of the proposed restructuring of the electric power
industry are currently unclear. It may benefit the natural gas industry by
creating more demand for gas turbine generated electric power, or it may hamper
demand by allowing more effective use of surplus electric capacity through
increased wheeling as a result of open access. At this time, the Company is not
projecting a significant increase in gas demand as a result of such
restructuring.
 
     Customers of the interstate pipeline operations of the Company include
natural gas producers, marketers and end-users, as well as other gas
transmission and distribution companies. Substantially all of the revenues of
these operations are generated under long-term gas transmission contracts.
Contracts representing approximately 70 percent of the Company's firm
transportation capacity will be expiring over the next four years, principally
in the year 2000. Although the Company cannot predict how much capacity will be
resubscribed, a majority of the expiring contracts cover service to Northeastern
U.S. markets, where there is currently little excess capacity. Several projects,
however, have been proposed to deliver incremental volumes to this area. While
the Company intends to pursue the renegotiation, extension and/or replacement of
these contracts, there can be no assurance as to whether the Company will be
able to extend or replace these contracts (or a substantial portion thereof) or
that the terms of any renegotiated contracts will be as favorable to the Company
as the existing contracts. Accordingly, the Company presently is unable to
ascertain whether or not the expiration and renegotiation, extension and/or
replacement of these transportation contracts will have a materially adverse
effect on the Company's financial position or results of operations.
 
     In a number of key markets, the Company faces competitive pressure from
other major pipeline systems, enabling local distribution companies and
end-users to choose a supplier or switch suppliers based on the short-term price
of gas and the cost of transportation. Competition between pipelines is
particularly intense in the Company's supply area, Louisiana and Texas. In some
instances, the Company has had to discount its
 
                                        3

transportation rates in order to maintain market share. The renegotiation of the
Company's expiring contracts may be impacted by the foregoing competitive
factors.
 
                            NON-REGULATED OPERATIONS
 
  Field and Merchant Services
 
     Certain subsidiaries of EPTPC are engaged in the businesses of marketing
natural gas and owning and operating approximately 1,300 miles of gathering and
intrastate pipelines that serve the Texas Gulf Coast and West Texas markets.
 
     The interstate marketing operations buy, sell and contract for the
transportation of up to 1.2 Bcf/d of natural gas from approximately 300
suppliers, through 40 pipelines to about 500 customers, marketers and end-users.
The Company offers a portfolio of products and services that are intended to
help distributors, end-users and producers manage their gas sales and purchasing
processes. The Company also owns and manages gas gathering systems and natural
gas processing plants in Pennsylvania, Texas, Louisiana and Tennessee.
Additionally, the Company owns and operates, either directly or through joint
ventures, approximately 1,300 miles of intrastate pipelines and gathering lines
in the Texas Gulf Coast and West Texas markets. In addition to offering
transportation capacity, these intrastate pipeline and gathering operations
manage buying, selling and transportation services of up to 1.4 Bcf/d of natural
gas for approximately 135 suppliers and 140 customers and shippers. The
intrastate pipeline operations also provide swing storage services and access to
major intrastate and interstate pipelines in Texas.
 
     The following table sets forth the volumes of gas sold and transported by
the Company's marketing and intrastate pipeline subsidiaries for the periods
indicated:

     In February 1994, the Company sold a 20 percent interest in its marketing
and intrastate pipeline subsidiary to Ruhrgas Aktiengesellschaft, Germany's
largest natural gas company. In anticipation of the Merger, the Company
repurchased this 20 percent interest in September 1996.
 
  International and Other Energy-Related Business
 
     The Company has recently undertaken various activities to extend its
traditional activities in North American pipelines to international pipeline,
power and energy-related projects, with a current focus on activities in Latin
America, Southeast Asia, Australia and Europe. Set forth below are brief
descriptions of the projects that are operational or are in various stages of
development.
 
     Australia Project. In 1995, a subsidiary of the Company was selected to
construct, own and operate a 470-mile natural gas pipeline in Queensland,
Australia. Construction of the pipeline was completed in December 1996 at a
total cost of $170 million. Additionally, in June 1995 the Company acquired the
natural gas pipeline assets of PASA, which includes a 488-mile pipeline, for
$225 million. In December 1996, the Company received approximately $400 million
through debt financing and the subsequent sale of 70 percent of its ownership
interest in these projects.
 
     Indonesia Project. The Company has a 50 percent ownership interest in a
producing gas field (having reserves of approximately 500 Bcf) and a 47.5
percent ownership interest in a 135 MW power generating plant under construction
in South Sulawesi, Indonesia. The $225 million project has been financed with
approximately $179 million in debt. The electricity from the power generating
plant will be sold to the national electric utility pursuant to a long-term
contract. The Company has obtained political risk insurance for its equity
investment.
 
                                        4

     Hungary Project. In September 1996, a subsidiary of the Company was
selected to acquire a 50 percent controlling interest in an operating 70 MW
power plant located in Dunaujvaros, Hungary. The electricity generated at this
plant is consumed by Dunaferr, the largest steel mill in Hungary. Excess power
is sold pursuant to long-term contracts to the Hungarian national electric
utility. Subject to satisfaction of certain conditions, the acquisition is
scheduled to be finalized in the first quarter of 1997. The assets will be
acquired for approximately $25 million and no financing will be involved. The
Company is seeking political risk insurance from the Overseas Private Investment
Corporation for its equity investment. The acquisition agreement requires the
Company to study and, if deemed economically feasible, to expand the electric
generating plant. The feasibility study is underway.
 
     Other Projects. The Company has a 17.5 percent interest in a 240 MW power
plant in Springfield, Massachusetts, and a 50 percent interest in two additional
cogeneration projects in Florida which have a combined capacity of 220 MWs.
 
  Other
 
     As a result of the Merger, the Company holds certain limited assets and is
responsible for certain liabilities, which the Company estimates to be
approximately $600 million, of existing and discontinued operations and
businesses.
 
     Tenneco Credit Corporation (now renamed El Paso Energy Credit Corporation),
an indirect subsidiary of the Company, purchases interest-bearing and
noninterest-bearing trade receivables from the Company's operating subsidiaries.
Through June 1994, it also purchased retail receivables generated primarily by
retail sales of products by Case Corporation. As part of the intercompany
transfers preceding the Merger and Distributions, these Case Corporation retail
receivables and all of the interest and obligations associated with receivables
relating to the Industrial Business were transferred to New Tenneco.
 
                                 ENVIRONMENTAL
 
     The Company is subject to extensive federal, state, and local laws and
regulations governing environmental quality and pollution control. These laws
and regulations require the Company to remove or remedy the effect on the
environment of the disposal or release of specified substances at ongoing and
former operating sites. As of December 31, 1996, the Company had a reserve of
approximately $187 million for the following environmental contingencies which
the Company anticipates incurring through 2002: (i) expected remediation costs
and associated onsite, offsite and groundwater technical studies of
approximately $134 million; and (ii) other costs of approximately $53 million.
For a further discussion of specific environmental matters, see Item 3, Legal
Proceedings, Item 7, Management's Discussion and Analysis of Financial Condition
and Results of Operations, and Note 5 of Item 8, Financial Statements and
Supplementary Data.
 
     In addition, the Company estimates that it will make capital expenditures
for environmental matters of approximately $5 million in 1997 and that capital
expenditures for environmental matters will range from approximately $40 million
to $80 million in the aggregate for the years 1998 through 2007. These
expenditures primarily relate to compliance with air regulations and control of
water discharges.
 
                                   EMPLOYEES
 
     The Company had approximately 2,800 full-time employees on December 31,
1996. Subsequent to the Merger, the Company implemented a program to streamline
operations and reduce operating costs. Since December 31, 1996, the Company has
reduced its workforce by 340 employees. The Company has no collective bargaining
arrangements.

     The Company is of the opinion that it has generally satisfactory title to
the properties owned and used in its businesses, subject to the liens for
current taxes, liens incident to minor encumbrances, and easements and
restrictions that do not materially detract from the value of such property or
the interests therein or the use of such properties in its businesses. In
addition, the Company's physical properties are adequate and suitable for the
conduct of its business in the future.

ITEM 3. LEGAL PROCEEDINGS
 
     In July 1996, TGP was served with a complaint in the matter of Jack J.
Grynberg v. Alaska Pipeline Co., et al., filed in the U.S. District Court for
the District of Columbia. The plaintiff filed this action under the False Claims
Act against most interstate pipelines and others alleging that the defendants
mismeasured natural gas produced from federal and Indian lands, which deprived
the United States of royalties otherwise due it. Among other things, the
plaintiff seeks to recover unspecified treble damages on behalf of the United
States. The plaintiff is also seeking to recover his finder's fee and attorneys'
fees. All defendants, most of whom are pursuing a combined defense, have filed
responsive motions. The plaintiff responded to those motions in January 1997.
Oral arguments are set for March 1997. TGP believes that there are valid
jurisdictional and procedural defenses to the plaintiff's complaint; however,
even if the plaintiff is ultimately entitled to pursue his claims, TGP believes
that it has substantive defenses, including that TGP's
measurement practices are consistent with industry practice and all applicable
standards, regulations, contracts, and tariffs and that TGP should not be liable
in any event. Based on information available at this time, TGP does not believe
that the ultimate resolution of this matter will have a materially adverse
effect on the Company's financial position or results of operations.
 
     On August 1, 1995, the Texas Supreme Court affirmed a ruling of the Texas
Court of Appeals favorable to TGP involving a gas purchase contract and
indicated that it would remand the case to the trial court. On April 18, 1996,
however, the Texas Supreme Court withdrew its initial opinion and issued an
opinion reversing the Court of Appeals opinion. In June 1996, TGP filed a motion
for rehearing with the Texas Supreme Court which was denied in August 1996. In
December 1996, TGP entered into settlement agreements with each of the parties
to this gas purchase contract. As a result of these settlements, the gas
purchase contract is now terminated. TGP paid a total of $74 million to
terminate this contract. In addition, all related litigation was terminated.
During the course of this action, TGP either paid, or provided for the payment
of, amounts it believes were appropriate to cover the resolution of its contract
reformation litigation, including providing a bond in the amount of $206
million. On September 30, 1996, TGP paid approximately $193 million to the
producers and the producers agreed to release all but approximately $2 million
of the bonded amount. On November 1, 1996, a final order was issued which
assessed only $456,000 of the $2 million to TGP and TGP was released from the
remaining bond amount. TGP has filed with FERC to recover these payments from
its customers.
 
     On October 14, 1993, TGP was sued in the State District Court of Ector
County, Texas, by ICA and TransTexas. In that suit, ICA and TransTexas contended
that TGP had an obligation to purchase gas production which TransTexas
unilaterally attempted to add to the reserves originally dedicated to a 1979 gas
contract. An amendment to the pleading sought $1.5 billion from TGP for alleged
damages caused by TGP's refusal to purchase gas produced from the TransTexas
leases covering the new production and lands. In June 1996, TGP reached a
settlement with ICA and TransTexas for $125 million wherein ICA and TransTexas
agreed to terminate their contract rights, released TGP from liability under the
contract, and indemnified TGP against future claims, including royalty owner
claims. TGP has filed with FERC to recover from its customers amounts previously
paid to TransTexas above the market price as well as the $125 million settlement
payment. In connection with that litigation, certain royalty interest owners
filed a claim against TGP alleging that they are sellers entitled to tender gas
to TGP under the settled contract. This claim fell under the indemnification
provisions of TGP's settlement with ICA and TransTexas, requiring ICA and
TransTexas to defend and indemnify TGP. This royalty owner litigation was
settled in December 1996 at no cost to TGP. The royalty owners' claims against
TGP have been dismissed.
 
     TGP is a party in proceedings involving federal and state authorities
regarding the past use by TGP of a lubricant containing PCBs in its starting air
systems. TGP has executed a consent order with the EPA governing the remediation
of certain of its compressor stations and is working with the Pennsylvania and
New York environmental agencies to specify the remediation requirements at the
Pennsylvania and New York stations. Remediation activities in Pennsylvania are
essentially complete; in addition, pursuant to the Consent Order dated August 1,
1995, between TGP and the Pennsylvania Department of Environmental Protection,
TGP funded an environmentally beneficial project for $450,000 in April 1996 and
paid a $500,000 civil penalty in September 1996. Remediation and
characterization work at the compressor stations under its consent order
 
                                        7
<PAGE>   11
 
with the EPA and the jurisdiction of the New York Department of Environmental
Conservation is ongoing. Management believes that the ultimate resolution of
these matters will not have a materially adverse effect on the Company's
financial position or results of operations.
 
     In Commonwealth of Kentucky, Natural Resources and Environmental Protection
Cabinet v. Tennessee Gas Pipeline Company (Franklin County Circuit Court, Docket
No. 88-C1-1531, November 16, 1988), the Kentucky environmental agency alleged
that TGP discharged pollutants into the waters of the state without a permit and
disposed of PCBs without a permit. The agency sought an injunction against
future discharges, sought an order to remediate or remove PCBs, and sought a
civil penalty. TGP has entered into agreed orders with the agency to resolve
many of the issues raised in the original allegations, has received water
discharge permits for its Kentucky stations from the agency, and continues to
work to resolve the remaining issues. Management believes that the resolution of
this issue will not have a materially adverse effect on the Company's financial
position or results of operations.
 
     The Company is a named defendant in numerous lawsuits and a named party in
numerous governmental proceedings arising in the ordinary course of business.
While the outcome of such lawsuits or other proceedings against the Company
cannot be predicted with certainty, management currently does not expect these
matters to have a materially adverse effect on the Company's financial position
or results of operations.

                                    PART II
 
ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED
        STOCKHOLDER MATTERS
 
     Following the consummation of the Merger, a subsidiary of EPG became the
sole holder of EPTPC's common stock, par value $.01 per share (the "Common
Stock"). The Common Stock was delisted from the New York Stock Exchange, and
there is no longer a trading market for such securities.
 
     The declaration of dividends on EPTPC capital stock is at the discretion of
its Board of Directors. The Board of Directors has not adopted a dividend policy
as such; subject to legal and contractual restrictions, its decisions regarding
dividends are based on all considerations that in its business judgment are
relevant at the time, including past and projected earnings, cash flows,
economic, business and securities market conditions and anticipated developments
concerning EPTPC's business and operations. For additional information
concerning the payment of dividends by EPTPC, see Item 7, Management's
Discussion and Analysis of Financial Condition and Results of Operations.
 
     EPTPC's cash flow and the consequent ability of EPTPC to pay any dividends
on its Common Stock is substantially dependent upon EPTPC's earnings and cash
flow available after its debt service and the availability of such earnings to
EPTPC by way of dividends, distributions, loans and other advances. The
instruments setting forth the rights of the holders of the Series A Preferred
Stock contain provisions restricting EPTPC's right to pay dividends and make
other distributions on the Common Stock.
 
     Under applicable corporate law, dividends may be paid by EPTPC out of
"surplus" (as defined under the law), or, if there is not a surplus, out of net
profits for the year in which the dividends are declared or the preceding fiscal
year. At December 31, 1996, EPTPC had surplus of approximately $1.2 billion for
the payment of dividends, and EPTPC will also be able to pay dividends out of
any net profits for the current and prior fiscal year.

ITEM 6. SELECTED FINANCIAL DATA
 
     The consolidated and combined selected financial data as of December 31,
1996, 1995, and 1994 and for the years ended December 31, 1996, 1995, 1994, and
1993 were derived from the audited consolidated and combined financial
statements of the Company. The combined selected financial data as of
December 31, 1993 and 1992 and for the year ended December 31, 1992 are
unaudited and were derived from the accounting records of Old Tenneco. In the
opinion of EPTPC's management, the combined selected financial data of the
Company as of December 31, 1993 and 1992 and for the year ended December 31,
1992 include all adjusting entries (consisting only of normal recurring
adjustments) necessary to present fairly the information set forth therein. The
balance sheet of EPTPC and consolidated subsidiaries as of December 31, 1996,
contained herein reflects the purchase price recorded by EPG effective as of
December 31, 1996 and is referred to herein as "Post-Acquisition Consolidated".
The combined statements of income, cash flows and changes in consolidated
stockholders' equity and combined equity for periods prior to December 31, 1996
are referred to as "Pre-Acquisition Combined". As a result of the change in the
basis of accounting from historical cost to reflect EPG's purchase cost, the
combined financial statements for Pre-Acquisition periods are not comparable to
the consolidated balance sheet for the Post-Acquisition period. This information
should be read in conjunction with Item 7, Management's Discussion and Analysis
of Financial Condition and Results of Operations, and Item 8, Financial
Statements and Supplementary Data.

    in the Company's two Australian pipelines and completed the sale of its oil
    and gas exploration, production and financing unit, Tenneco Ventures. During
    1995, 1994 and 1993, EPTPC completed several acquisitions and dispositions,
    the most significant of which was the acquisition of the natural gas

    based on the ratio of the Industrial Business' and Shipbuilding Business'
    net assets to Old Tenneco's consolidated net assets plus debt. Old Tenneco's
    historical practice has been to incur indebtedness for its consolidated
    group at the parent company level or at a limited number of subsidiaries,
    rather than at the operating company level, and to centrally manage various
    cash functions. Management believes that the historical allocation of
    corporate debt and interest expense is reasonable; however, it is not
    necessarily indicative of EPTPC's debt and interest expense which may be
    incurred in the future. See Note 15 of Item 8, Financial Statements and
    Supplementary Data.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
                               MERGER TRANSACTION
 
     On December 12, 1996, Old Tenneco and an indirect subsidiary of EPG
completed the Merger and Old Tenneco became an indirect subsidiary of EPG. The
Merger was effected in accordance with the Merger Agreement. In the Merger, Old
Tenneco changed its name to EPTPC. Prior to the Merger, Old Tenneco and its
subsidiaries effected various intercompany transfers and distributions which
restructured, divided and separated their businesses, assets and liabilities so
that all the assets, liabilities and operations related to the Industrial
Business and the Shipbuilding Business were spun-off to Old Tenneco's then
existing common stockholders in the Distributions. The entity consisting of the
Industrial Business was subsequently renamed Tenneco Inc. (referred to herein as
"New Tenneco") and the entity consisting of the Shipbuilding Business was
subsequently renamed Newport News. Following the Distributions, the remaining
operations of the Company consisted primarily of those operations related to the
transmission and marketing of natural gas and the discontinued operations of Old
Tenneco. In preparation for the Merger and Distributions, Old Tenneco initiated
the Debt Realignment. As part of the Debt Realignment, Old Tenneco initiated
tender offers for certain issues of debt of Old Tenneco and certain of its
subsidiaries and certain other debt issues which were exchanged into New Tenneco
debt, defeased, or otherwise retired. Upon completion of the Debt Realignment
transactions, the Company is only responsible for its remaining debt which was
not tendered, exchanged, defeased or otherwise retired. As a result of the
Merger, EPG owns 100 percent of the common stock of EPTPC, representing at the
effective time of the Merger approximately 75 percent of the equity value of
EPTPC; the balance of the equity value of EPTPC is held by the holders of its
Series A Preferred Stock that was issued in a registered public offering in
November 1996 and remains outstanding. For a further discussion, see Note 1 of
Item 8, Financial Statements and Supplementary Data.
 
                             RESULTS OF OPERATIONS
 
     Results of operations comparisons have been conformed to the
reclassification of the Combined Statements of Income.
 
YEAR ENDED DECEMBER 31, 1996, COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Operating Revenues
 
     The Company's operating revenues in 1996 increased by 38 percent over the
operating revenues in 1995. Revenues from the energy-related operations of the
Company that are subject to regulation by FERC (generally referred to herein as
its "regulated" operations) increased to $861 million, or 13 percent. Of the
increase, $55 million was primarily due to benefits derived from a new rate
structure implemented on July 1, 1995 and $34 million was due to regulatory
adjustments that had no operating income impact. Revenues from the
energy-related operations of the Company that are not generally subject to
regulation by FERC (generally referred to herein as its "non-regulated"
operations) increased 60 percent to $1.8 billion, primarily due to higher
natural gas prices and volumes. Additionally, the acquisition of the assets of
PASA in June 1995 and new processing and gathering projects increased revenues
by $44 million. Revenues in 1996 from other operations were $29 million compared
with $59 million in the prior year due to lower interest revenue from the
continuing liquidation of Case Corporation receivables.
 
  Operating Income
 
     Operating income from regulated operations increased to $250 million or 40
percent in 1996 due to benefits derived from the new rate structure and
increased transportation volumes. Additionally, approximately $42 million of
environmental costs were reflected in 1995 and offset by insurance recoveries as
a result of the environmental settlement. These insurance recoveries were
included in other income as discussed
 
                                       11
<PAGE>   15
 
below. Offsetting this increase were transition costs recognized in 1996 related
to the Merger and higher operating costs.
 
     Non-regulated operating losses were $6 million in 1996 compared with income
of $3 million in 1995. 1996 increases included higher volumes and prices from
Tenneco Ventures' oil and gas production of $11 million and the acquisition of
PASA in June 1995 which contributed $10 million. Tenneco Ventures and 70 percent
of the Company's interest in the Australian pipelines were sold in December 1996
subsequent to the Merger. These increases were offset primarily by lower margins
from marketing activities.
 
     Operating losses from other operations of the Company increased to $62
million or 26 percent in 1996 primarily due to lower interest revenue from the
continuing liquidation of Case Corporation receivables. In anticipation of the
Merger, Old Tenneco sold all of the Case Corporation retail receivables to New
Tenneco for an amount equal to their book value. Accordingly, income from these
receivables will not be recognized in future periods.
 
  Other (Income) and Expense
 
     Other expense increased to $19 million in 1996. The increase resulted from
a $30 million gain recognized in 1995 from the sale of Kern River, the absence
of earnings due to the sale of Kern River which contributed $33 million in 1995,
higher interest expense in 1996 of $20 million due to higher levels of debt, and
insurance recoveries in 1995 related to environmental costs, as discussed above.
Offsetting these items were $15 million in legal settlements and the recognition
of a $32 million deferred gain on the sale of certain investments. Additionally,
1995 included a $30 million reserve for estimated regulatory and legal
settlement costs and a $25 million reserve for the liquidation of surplus real
estate holdings.
 
     Prior to the Merger, Old Tenneco's historical practice has been to incur
indebtedness for its consolidated group at the parent company level or at a
limited number of subsidiaries, rather than at an operating company level, and
to centrally manage various cash functions. Consequently, the corporate debt of
Old Tenneco and its related interest expense have been allocated to Old
Tenneco's automotive, packaging and shipbuilding businesses ("Old Tenneco's
former non-energy operations") based upon the portion of Old Tenneco's
investment in Old Tenneco's former non-energy operations which was deemed to be
debt, generally based upon the ratio of Old Tenneco's former non-energy
operations' net assets to Old Tenneco's consolidated net assets plus debt.
Interest expense was allocated at a rate equivalent to the weighted average cost
of all corporate debt, which was 8.2 percent, 7.7 percent and 8.3 percent for
1996, 1995 and 1994, respectively. Total pre-tax interest expense allocated to
Old Tenneco's former non-energy operations in 1996, 1995 and 1994 was $211
million, $180 million and $120 million, respectively. Old Tenneco's former
non-energy operations have also been allocated tax benefits approximating 35
percent of the allocated pre-tax interest expense. Although interest expense and
the related tax effects have been allocated to Old Tenneco's former non-energy
operations for financial reporting on a historical basis, Old Tenneco's former
non-energy operations have not been billed for these amounts. The changes in
allocated corporate debt and the after-tax allocated interest expense have been
included as a component of the combined equity of the Company. Although
management believes that the historical allocation of corporate debt and
interest is reasonable, it is not necessarily indicative of the debt and
interest expense of the Company subsequent to the Merger or the debt that it may
incur in the future.
 
  Income Tax Expense (Benefit)
 
     Income tax expense for 1996 was $34 million compared to an $11 million
income tax benefit for 1995. The effective tax rate was 20.9 percent and (7.5)
percent for 1996 and 1995, respectively. The increase in tax expense resulted
primarily from the realization of tax benefits totaling $38 million in 1996
compared to $72 million in 1995. For an additional discussion of income taxes,
see Note 7 of Item 8, Financial Statements and Supplementary Data.
 
                                       12
<PAGE>   16
 
  Extraordinary Loss
 
     In preparation for the Merger and Distributions, Old Tenneco initiated a
realignment of its indebtedness. Upon completion of the debt realignment
transactions, the Company is only responsible for its remaining debt which was
not tendered, exchanged, defeased or otherwise retired (approximately $265
million of such debt remained outstanding immediately after the Merger). The
Company recognized an after-tax extraordinary charge of $234 million related to
the debt realignment immediately prior to the Merger.
 
YEAR ENDED DECEMBER 31, 1995, COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
  Operating Revenues
 
     Operating revenues for 1995 decreased by 18 percent compared with 1994. The
regulated operations experienced a decline in revenues from $920 million in 1994
to $761 million in 1995. Lower regulated merchant gas sales caused a decline of
approximately $222 million. Under FERC Order No. 636, customers assume the
responsibility for acquiring their gas supplies, reducing sales by the pipeline.
Other non-recurring regulatory adjustments, that had no operating income impact,
partially offset the decrease in revenues by $63 million. Revenues in the
nonregulated operations in 1995 were $1,155 million, down $299 million compared
with 1994. Average natural gas prices were lower in 1995 compared with 1994,
contributing approximately $175 million to the revenue decrease. Furthermore,
natural gas volumes declined, contributing $148 million to the revenue decrease.
Warmer weather in early 1995 resulted in lower levels of storage activity during
the year, decreasing demand for natural gas and forcing prices lower. These
effects were offset somewhat by approximately $18 million in revenues earned by
the PASA assets which were acquired by the Company in June 1995. Revenues from
the other operations of the Company were $59 million in 1995 compared with $47
million in 1994.
 
  Operating Income
 
     Operating income from regulated operations was down by $99 million in 1995
as compared with 1994 primarily due to the termination or expiration of
transportation contracts and an $11 million benefit recognized in 1994 from the
Columbia Gas contract settlement. Additionally, approximately $42 million of
environmental costs were reflected in 1995 and offset by insurance recoveries as
a result of the environmental settlement. These insurance recoveries are
included in other income as discussed below. The 1995 operating income for the
nonregulated business decreased by $11 million compared with 1994. The operating
income decline was due to increased startup and development costs on
international programs of approximately $12 million, lower margins and volumes
due to lower demand in gas marketing which resulted in a $9 million decrease,
and an increase in administrative costs of approximately $5 million. These
decreases were partially offset by approximately $9 million in operating income
from the PASA assets during the last half of 1995. The Company's other
operations reported an operating loss of $49 million in 1995 compared to $41
million in 1994.
 
  Other (Income) and Expense
 
     Other income increased to $14 million in 1995. The increase resulted from a
$30 million gain recognized in 1995 from the sale of Kern River, lower interest
expense of $20 million, and insurance recoveries related to environmental costs,
as discussed above. These increases were partially offset by a $23 million gain
from the 1994 sale of a 20 percent interest in the Company's marketing and
intrastate pipeline subsidiary to Ruhrgas Aktiengesellschaft, a $7 million loss
on the 1995 sale of TGP's interest in Ozark, a $30 million reserve for estimated
regulatory and legal settlement costs, and a $25 million charge to establish a
reserve for liquidation of surplus real estate holdings and notes. The Company
reacquired Ruhrgas Aktiengesellschaft's interest in the marketing and intrastate
pipeline subsidiary in September 1996.
 
  Income Tax Expense (Benefit)
 
     Income tax benefit for 1995 was $11 million compared with income tax
expense of $72 million in 1994. The effective tax rate for 1995 was (7.5)
percent compared with 32 percent in 1994.

                        LIQUIDITY AND CAPITAL RESOURCES
 
CASH FROM OPERATING ACTIVITIES
 
     Net cash used in operating activities was $27 million for 1996, compared
with $765 million of net cash provided by operating activities for 1995. This
decrease was due primarily to a reduction in the level of trade receivables
sold, which was $370 million lower in 1996 compared with 1995. Operating cash
flow in 1996 also declined $374 million as a result of higher tax payments
compared with 1995 due to the settlement of 1987 through 1989 federal tax
liabilities and TGP's gas contract settlements of $392 million.
 
     Net cash provided by operating activities was $765 million for 1995
compared with $278 million of net cash used in operating activities for 1994.
The Company generated $783 million from the collection and sale of customer
receivables in 1995 compared with $245 million in 1994. This was due to the sale
of $470 million of receivables and the collection of Case Corporation retail
receivables in 1995.
 
CASH FROM INVESTING ACTIVITIES
 
     The sale of businesses and assets generated $465 million during 1996
compared with $17 million in 1995 and $68 million in 1994, respectively. These
sales included a 50 percent interest in Kern River, 70 percent of the Company's
interests in two natural gas pipeline systems in Australia and the sale of the
Company's oil and gas exploration, production and financing unit, formerly known
as Tenneco Ventures.
 
     In 1996, the Company reacquired for $41 million the 20 percent interest in
the Company's marketing and intrastate pipeline subsidiary. PASA was acquired
for approximately $225 million in 1995.
 
     The Company invested $323 million in capital expenditures in its existing
businesses during 1996, $337 million during 1995 and $345 million during 1994.
The Company's planned capital and investment expenditures for 1997 of $254
million are primarily for the maintenance of pipeline systems and other
facilities, expansion of international operations and non-regulated operations,
and system enhancements.
 
     During 1996, subsequent to the Merger, the Company made advances to EPG of
approximately $170 million.
 
     Future funding for capital expenditures, acquisitions, and other investing
expenditures will be provided by internally generated funds, debt issuances,
available credit facilities and/or contributions from EPG.
 
CASH FROM FINANCING ACTIVITIES
 
     Net cash used in financing activities was $177 million during 1996, $150
million more than the same period in 1995. Dividends paid on Old Tenneco common
and preferred stock during 1996 were $321 million. The Company repurchased $172
million of common stock in 1996, down $483 million from the previous year.
During 1996, the Company had net borrowings under credit facilities and
short-term debt of approximately $1.2 billion, including amounts borrowed under
EPTPC's Revolving Credit and Competitive Advance Facility (the "Credit
Facility"). The proceeds from the 1996 short-term borrowings were generally
utilized to pay distributions to affiliates, dividends, capital expenditures and
to fund other operating cash flow uses discussed above. Old Tenneco also retired
$2.3 billion of long-term debt in 1996 compared to $497 million retired in 1995.
In November 1996, $296 million of Series A Preferred Stock was issued in a
registered public offering and remains outstanding. Finally, the Company
received contributions of $476 million in cash from affiliates, as compared to
contributions from affiliates of $320 million received in 1995. Cash
contributions from and distributions to affiliates vary based on cash generated
by affiliates from operations net of cash required for operating and investing
activities.
 
     Net cash used in financing activities was $27 million during 1995. In
addition to business expansion, the Company used its cash flow during 1995 for
the scheduled retirement of $497 million in long-term debt, to reacquire Old
Tenneco Common Stock for $655 million and to pay $286 million in dividends on
Old Tenneco stock. In addition, the Company issued approximately $1 billion of
total short-term and long-term debt in
 
                                       14
<PAGE>   18
 
1995. During 1994, the Company had a net reduction of $605 million in debt and
paid dividends on Old Tenneco stock of $318 million. Other cash sources included
net contributions from affiliates of $1.4 billion.
 
     Future funding for long-term debt retirements, dividends, and other
financing expenditures will be provided by internally generated funds, debt
issuances, available credit facilities and/or contributions from EPG.
 
LIQUIDITY
 
     Historically, excess net cash flows from operating and investing activities
have been used to meet consolidated debt and other obligations. Conversely, when
cash requirements have been in excess of cash flows from operations, the Company
has utilized its consolidated credit facilities to fund the EPTPC obligations.
Also, depending on market and other conditions, EPTPC has utilized external
sources of capital to meet specific funding requirements.
 
     Prior to the Merger, Old Tenneco restructured its consolidated indebtedness
for money borrowed pursuant to the Debt Realignment through a series of tender
offers, exchange offers, payments, defeasances, and prepayments. At December 31,
1996, the Company's outstanding debt consisted of $265 million of long-term debt
which remained outstanding after the Debt Realignment and $1.6 billion of
borrowings under the $3 billion Credit Facility.
 
     In February 1997, EPG issued 3 million shares of its common stock resulting
in net proceeds of $152 million. This amount was used to reduce the $1.6 billion
outstanding under the Credit Facility at December 31, 1996. The availability of
borrowings under the Company's agreements and facilities is subject to its
ability at the time to meet certain specified conditions, which management
believes it currently meets. These conditions include compliance with the
financial covenants and ratios required by such agreements, absence of default
under such agreements, and continued accuracy of the representations and
warranties contained in such agreements (including the absence of any material
adverse changes since the specified dates).
 
     In February 1997, TGP's shelf registration statement on Form S-3 filed with
the SEC covering an aggregate of $1 billion unsecured debt securities was
declared effective. In March 1997, TGP issued $900 million of long-term debt,
the proceeds of which were used to pay down the Credit Facility.
 
     At December 31, 1996, the Company's balance sheet reflected a negative
working capital balance of $519 million. This included $700 million of
borrowings under the Credit Facility and a $167 million rate refund payable
which will be refunded to customers in March 1997.
 
     The Company believes its internally generated funds from operations,
available credit facilities and contributions from EPG will provide adequate
sources of working capital and funds to finance its future capital requirements.
 
                         COMMITMENTS AND CONTINGENCIES
 
  Capital Commitments
 
     At December 31, 1996, the Company had capital or investment commitments of
$36 million which are expected to be funded through cash provided by operations
and/or incremental borrowings. The Company's other planned capital and
investment projects are discretionary in nature, with no substantial capital
commitments made in advance of the actual expenditures.
 
  Purchase Obligations
 
     In connection with the financing commitments of certain joint ventures, the
Company has entered into unconditional purchase obligations for products and
services of $121 million ($94 million on a present value basis) at December 31,
1996. The Company's annual obligations under these agreements are $22 million
for the years 1997 and 1998, $21 million for the years 1999 and 2000, and $11
million for the year 2001. Payments
 
                                       15
<PAGE>   19
 
under such obligations, including additional purchases in excess of contractual
obligations, were $25 million, $26 million and $34 million for the years 1996,
1995 and 1994, respectively. In addition, in connection with the Great Plains
coal gasification project, TGP continues to have an obligation to purchase 30
percent of a capped volume of the plant output through July 2009. TGP has
executed a settlement of this contract as a part of its GSR negotiations
discussed in "Rates and Regulatory Matters," below.
 
  Guarantees
 
     The Company has guaranteed various obligations of its subsidiaries, which
obligations are not expected to exceed $3 million. For further information, see
Note 4 of Item 8, Financial Statements and Supplementary Data.
 
  Rates and Regulatory Matters
 
     A phased proceeding was scheduled at FERC with respect to the recovery of
TGP's GSR costs. Testimony has been completed in connection with Phase I of that
proceeding relating to the eligibility of GSR cost recovery. Phase II of the
proceeding on the prudency of the costs to be recovered and on certain contract
specific eligibility issues has not yet been scheduled. Although the Order No.
636 transition cost recovery mechanism provides for complete recovery by
pipelines of eligible and prudently incurred transition costs, certain customers
have challenged the prudence and eligibility of TGP's GSR costs and settlement
discussions have been entered into with TGP's customers concerning the amount of
such costs in response to FERC's public statements encouraging such settlements.
 
     On February 28, 1997, TGP filed with FERC a proposed settlement of all
issues related to the recovery by TGP of its GSR and other transition costs and
related proceedings (the "GSR Stipulation and Agreement"). Upon final approval
by FERC, this settlement will become effective retroactive to
January 1, 1997. The settlement is based upon a preliminary GSR understanding,
which called for sharing of transition costs, that EPG reached with TGP's
customers in October 1996 in anticipation of the Merger. The GSR Stipulation and
Agreement allows for TGP to recover up to $770 million in GSR and other
transition costs, including interest, of which approximately $531 million has
previously been recovered, subject to refund, pending resolution of the
transition cost issues. Assuming FERC approves the GSR Stipulation and
Agreement, TGP will be entitled to recover additional transition costs, up to
the remaining $239 million, through a two-year demand transportation surcharge
and an interruptible transportation surcharge. The terms of the GSR Stipulation
and Agreement provide for a rate case moratorium through November 2000
(subject to certain limited exceptions) and provide a rate cap, indexed to
inflation, through October 31, 2005, for certain of TGP's customers. The
purchase accounting adjustments reflected in the Company's consolidated
financial statements assume approval of the settlement with respect to TGP's GSR
and other transition costs in accordance with the terms of the GSR Stipulation
and Agreement.
 
     Although parties to TGP's transition cost proceedings do not have to
declare their support or opposition to the GSR Stipulation and Agreement until
mid-March, management believes that all of TGP's customers will support or not
oppose the GSR Stipulation and Agreement.
 
     In order to resolve litigation concerning purchases made by TGP of
synthetic gas produced from the Great Plains coal gasification plant, TGP, along
with three other pipelines, executed four separate settlement agreements with
Dakota and the U.S. Department of Energy and initiated four separate proceedings
at FERC seeking approval to implement the settlement agreements. Among other
things, the settlement required TGP to pay Dakota over a limited period a
premium over the spot price for Dakota's production and resolves the litigation
with Dakota. As of December 31, 1996, TGP had paid $87 million of this premium
obligation and has accrued its estimated remaining premium obligation through
December 2003 of $55 million. FERC previously ruled that the costs related to
the Great Plains project are eligible for recovery through GSR and other special
recovery mechanisms and that the costs are eligible for recovery for the
duration of the term of the original gas purchase agreements. In October 1994,
FERC consolidated the four proceedings and set them for hearing before an ALJ.
The hearing, which concluded in July 1995, was limited to the issue of whether
the settlement agreements are prudent. The ALJ concluded, in his initial
decision issued in December 1995, that
 
                                       16
<PAGE>   20
 
the settlement was not prudent. In December 1996, FERC unanimously reversed that
decision and upheld the settlements among the pipelines, the U.S. Department of
Energy and Dakota. No parties filed for rehearing of the FERC decision. TGP
notified Dakota in December 1996 that it accepted the settlement.
 
     In December 1994, TGP filed for a general rate increase (the "1995 Rate
Case"). In January 1995, FERC accepted the filing, suspended its effectiveness
for the maximum period of five months pursuant to normal regulatory process, and
set the matter for hearing. On July 1, 1995, TGP began collecting rates, subject
to refund, reflecting an $87 million increase in TGP's annual revenue
requirement. A Stipulation was filed with an ALJ in this proceeding in April
1996. This Stipulation resolves the rates that are the subject of the 1995 Rate
Case, including a structural rate design change that results in a larger
proportion of TGP's transportation revenues being dependent upon throughput.
Under the Stipulation, TGP is required to refund, upon final approval of the
Stipulation, the difference between the revenues collected under the July 1,
1995 motion rates and the revenues that would have been collected pursuant to
rates underlying the Stipulation. In October 1996, FERC approved the Stipulation
with certain modifications and clarifications which are not material. In January
1997, FERC issued an order denying requests for rehearing of the October 1996
order. Refunds will be made in March 1997. The Company has established a
provision for these refunds, and the balance of this provision at December 31,
1996 was $167 million. One party to the rate proceeding, a competitor of TGP,
filed with the Court of Appeals a Petition for Review of the FERC orders
approving the Stipulation.
 
     Management believes the ultimate resolution of the aforementioned rate and
regulatory matters, which are in various stages of finalization, will not have a
materially adverse effect on the Company's financial position. For a further
discussion of regulatory matters, see Note 5 of Item 8, Financial Statements and
Supplementary Data.
 
  Future Projects
 
     In September 1996, a subsidiary of the Company was selected to acquire a 50
percent controlling interest in an operating 70 MW power plant located in
Dunaujvaros, Hungary. The electricity generated at this plant is consumed by
Dunaferr, the largest steel mill in Hungary. Excess power is sold pursuant to
long-term contracts to the Hungarian national electric utility. Subject to
satisfaction of certain conditions, the acquisition is scheduled to be finalized
in the first quarter of 1997. The assets will be acquired for approximately $25
million and no financing will be involved. The Company is seeking political risk
insurance from the Overseas Private Investment Corporation for its equity
investment. The acquisition agreement requires the Company to study and, if
deemed economically feasible, to expand the electric generating plant. The
feasibility study is underway.
 
  Legal Proceedings
 
     See Item 3, Legal Proceedings which is incorporated herein by reference.
 
                                 ENVIRONMENTAL
 
     The Company is subject to extensive federal, state, and local laws and
regulations governing environmental quality and pollution control. These laws
and regulations require the Company to remove or remedy the effect on the
environment of the disposal or release of specified substances at ongoing and
former operating sites. As of December 31, 1996, the Company had a reserve of
approximately $187 million for the following environmental contingencies which
the Company anticipates incurring through 2002: (i) expected remediation costs
and associated onsite, offsite and groundwater technical studies of
approximately $134 million; and (ii) other costs of approximately $53 million.
For a further discussion of specific environmental matters, see Item 3, Legal
Proceedings and Note 5 of Item 8, Financial Statements and Supplementary Data.
 
     The Company and certain of its subsidiaries have been designated, have
received notice that they could be designated, or have been asked for
information to determine whether they could be designated as a PRP with respect
to 25 sites under the Comprehensive Environmental Response, Compensation and
Liability Act
 
                                       17
<PAGE>   21
 
(CERCLA or Superfund) or state equivalents. The Company has sought to resolve
its liability as a PRP with respect to these Superfund sites through
indemnification by third parties and/or settlements which provide for payment of
the Company's allocable share of remediation costs. As of December 31, 1996, the
Company has estimated its share of the remediation costs at these sites to be
between $7 million and $41 million and has provided reserves that it believes
are adequate for such costs. Because the clean-up costs are estimates and are
subject to revision as more information becomes available about the extent of
remediation required, the Company's estimate of its share of remediation costs
could change. Moreover, liability under the federal Superfund statute is joint
and several, meaning that the Company could be required to pay in excess of its
pro rata share of remediation costs. The Company's understanding of the
financial strength of other PRPs has been considered, where appropriate, in its
determination of its estimated liability as described herein. The Company
presently believes that the costs associated with the current status of such
entities as PRPs at the Superfund sites referenced above will not have a
materially adverse effect on the financial position or results of operations of
the Company.
 
     The Company estimates that its subsidiaries will make capital expenditures
for environmental matters of approximately $5 million in 1997 and that capital
expenditures for environmental matters will range from approximately $40 million
to $80 million in the aggregate for the years 1998 through 2007. These
expenditures primarily relate to compliance with air regulations and control of
water discharges.

  SFAS No. 71, Accounting for the Effects of Certain Types of Regulation
 
     The Company's businesses that are subject to the regulations and accounting
requirements of FERC continue to meet the accounting requirements of SFAS No.
71. The Consolidated and Combined Balance Sheets of the Company contain assets
and liabilities related to operations which have been recorded pursuant to SFAS
No. 71. If these accounting principles should no longer be applied, an amount
would be charged to earnings as an extraordinary item. At December 31, 1996,
this amount was estimated to be approximately $59 million, net of income taxes.
Changes in the regulatory and economic environment may, at some point in the
future, create circumstances in which the application of regulatory accounting
principles is no longer appropriate. Any potential charge would be non-cash and
would have no direct effect on the ability to seek recovery of the underlying
deferred costs in future rate proceedings or on the ability to collect the rates
set thereby. For a further discussion of SFAS No. 71 issues, see Note 2 of Item
8, Financial Statements and Supplementary Data.
 
  FERC Compliance Audits
 
     TGP, as with all interstate pipelines, is subject to a FERC audit review of
its books and records. TGP currently has an open audit covering the years 1991
through 1994. FERC audit staff is expected to issue its audit report in early
1997.
 
                             RECENT PRONOUNCEMENTS
 
     The Company adopted SFAS No. 125, SFAS No. 127 and Statement of Position
No. 96-1 effective January 1, 1997. The Company believes that these
pronouncements will not have a material impact on the Company's financial
position or results of operations. In addition, SFAS No. 128 and SFAS No. 129
were issued in early March 1997 and the Company is currently evaluating the
effect of these pronouncements. For a further discussion of these
pronouncements, see Note 2 of Item 8, Financial Statements and Supplementary
Data.

       CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS
            OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
 
     This report contains or incorporates by reference forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995. Where any such forward-looking statement includes a statement of the
assumptions or bases underlying such forward-looking statement, the Company
cautions that, while such assumptions or bases are believed to be reasonable and
are made in good faith, assumed facts or bases almost always vary from actual
results, and the differences between assumed facts or bases and actual results
can be material, depending upon the circumstances. Where, in any forward-looking
statement, the Company or its management expresses an expectation or belief as
to future results, such expectation or belief is expressed in good faith and is
believed to have a reasonable basis, but there can be no assurance that the
statement of expectation or belief will result or be achieved or accomplished.
The words "believe," "expect," "estimate," "anticipate" and similar expressions
identify forward-looking statements.
 
     Taking into account the foregoing, the following are identified as
important factors that could cause actual results to differ materially from
those expressed in any forward-looking statement made by, or on behalf of, the
Company:
 
HIGHLY COMPETITIVE INDUSTRY
 
          The ability to maintain or increase current transmission, gathering,
     processing, and sales volumes, or to remarket unsubscribed capacity, can be
     subject to the impact of future weather conditions, including those that
     favor other alternative energy sources; price competition; drilling
     activity and supply availability; and service competition. Future
     profitability also may be affected by the Company's ability to compete with
     the services offered by other energy enterprises which may be larger, offer
     more services, and possess greater resources. The ability of TGP to
     negotiate new contracts and to renegotiate existing contracts (70 percent
     of which are expiring over the next five years, principally in the year
     2000) could be adversely affected by the proposed construction of
     additional pipeline capacity in the Northeast U.S., reduced demand due to
     higher gas prices, the availability of alternative energy sources, and
     other factors that are not within its control. For a further discussion see
     Item 1, Business -- Regulated Operations -- Markets and Competition.
 
IMPACT OF NATURAL GAS AND NATURAL GAS LIQUIDS PRICES
 
          The value of natural gas transmission services is based on an all-in
     cost, including the cost of the natural gas. Therefore, the Company's
     ability to compete with other transporters is impacted by natural gas
     prices in the supply basins connected to its pipeline systems compared to
     prices in other gas producing regions, especially Canada. Additionally,
     revenues generated by the Company from its gathering and processing
     contracts are dependent upon volumes and rates, both of which can be
     affected by the prices of natural gas and natural gas liquids. Fluctuations
     in energy prices are caused by a number of factors, including regional,
     domestic and international demand, availability and adequacy of
     transportation facilities, energy legislation, federal or state taxes, if
     any, on the sale or transportation of natural gas and natural gas liquids
     and the price and abundance of supplies of alternative energy sources.
 
USE OF DERIVATIVE FINANCIAL INSTRUMENTS
 
          In the ordinary course and conduct of its business, some of the
     Company's non-regulated subsidiaries are engaged in the gathering,
     processing and marketing of natural gas and other energy commodities and
     utilize futures and option contracts traded on the New York Mercantile
     Exchange and Over-The-Counter options and price and basis swaps with other
     gas merchants and financial institutions. The Company could incur financial
     losses in future periods as a result of volatility in the market values of
     the underlying commodities.
 
                                       19
<PAGE>   23
 
ACQUISITIONS AND INVESTMENTS
 
          Opportunities for growth through acquisitions and investments in joint
     ventures, and future operating results and the success of acquisitions and
     joint ventures within and outside the U.S. may be subject to the effects
     of, and changes in, U.S. and foreign trade and monetary policies, laws and
     regulations, political and economic developments, inflation rates, and the
     effects of taxes and operating conditions. Activities in areas outside the
     U.S. also are subject to the risks inherent in foreign operations,
     including loss of revenue, property and equipment as a result of hazards
     such as expropriation, nationalization, war, insurrection and other
     political risks, and the effects of currency fluctuations and exchange
     controls. Such legal and regulatory delays and other unforeseeable
     obstacles may be beyond the Company's control or ability to manage.
 
PENDING REGULATORY PROCEEDINGS
 
          TGP has entered into comprehensive settlements with its customers
     that, if approved by FERC, would resolve many of the transportation rate,
     gas supply realignment and other transition issues in which it is involved.
     Whether FERC will approve such settlements in the form filed or whether
     these regulatory proceedings will be otherwise resolved in a manner
     satisfactory to the Company cannot be predicted with certainty, and the
     business of the Company could be adversely affected thereby. For a
     description of certain regulatory proceedings involving the Company, see
     Item 1, Business -- Regulated Operations -- Regulatory Environment.
 
POTENTIAL ENVIRONMENTAL LIABILITIES
 
          The Company may incur significant costs and liabilities in order to
     comply with existing environmental laws and regulations. It is also
     possible that other developments, such as increasingly strict environmental
     laws, regulations and enforcement policies thereunder, and claims for
     damages to property, employees, other persons and the environment resulting
     from current or discontinued operations, could result in substantial costs
     and liabilities in the future. For additional information concerning the
     Company's environmental matters, see Note 5 of Item 8, Financial Statements
     and Supplementary Data.
 
OPERATING HAZARDS AND UNINSURED RISKS
 
          While the Company maintains insurance against certain of the risks
     normally associated with the transportation, gathering and processing of
     natural gas, including explosions, pollution and fires, the occurrence of a
     significant event that is not fully insured against could have a material
     adverse effect on the Company.
 
POTENTIAL LIABILITIES RELATED TO THE MERGER
 
          The amount of the actual and contingent liabilities of Old Tenneco,
     which remained the liabilities of the Company after the Merger, could vary
     materially from the amount estimated by the Company, which was based upon
     assumptions which may prove to be inaccurate. If New Tenneco or Newport
     News were unable or unwilling to pay their respective liabilities, a court
     could require the Company, under certain legal theories which may or may
     not be applicable to the situation, to assume responsibility for such
     obligations, which could have a material adverse effect on the Company.
 
UNCERTAINTY SURROUNDING INTEGRATION OF OPERATIONS
 
          EPG is engaged in a comprehensive review of the business and
     operations of EPTPC and its subsidiaries and has begun to integrate such
     operations to increase operating and administrative efficiency through
     consolidation and reengineering of facilities, workforce reductions and
     coordination of purchasing, sales and marketing activities. Management
     anticipates that the complementary interstate and intrastate pipeline
     operations and energy marketing activities of the combined company should
     provide increased operating flexibility and access to additional customers
     and markets, although the amount and timing of the realization of such
     benefits will depend upon the Company's ability to integrate
 
                                       20
<PAGE>   24
 
     successfully the businesses and operations of the companies, and the time
     period over which such integration is effected.
 
POTENTIAL FEDERAL INCOME TAX LIABILITIES
 
          In connection with the Merger and Distributions, the IRS issued a
     private letter ruling to Old Tenneco, in which the IRS ruled that for U.S.
     federal income tax purposes: (i) the Distributions would be tax-free to Old
     Tenneco and, except to the extent cash was received in lieu of fractional
     shares, to its then existing stockholders; (ii) the Merger would constitute
     a tax-free reorganization; and (iii) that certain other transactions
     effected in connection with the Merger and Distributions would be tax-free.
     If the Distributions were not to qualify as tax-free distributions, then a
     corporate level federal income tax would be assessed to the consolidated
     group of which Old Tenneco was the common parent. This corporate level
     federal income tax would be payable by EPTPC. Under certain limited
     circumstances, however, New Tenneco and Newport News have agreed to
     indemnify EPTPC for a defined portion of such tax liabilities.
 
REFINANCING AND INTEREST RATE EXPOSURE RISKS
 
          The business and operating results of the Company can be adversely
     affected by factors such as the availability or cost of capital, changes in
     interest rates, changes in the tax rates due to new tax laws, market
     perceptions of the natural gas industry or the Company, or security
     ratings.
 
POTENTIAL FOR CHANGES IN ACCOUNTING STANDARDS
 
          Authoritative generally accepted accounting principle or policy
     changes from such standard setting bodies as the Financial Accounting
     Standards Board, FERC, and the SEC may affect the Company's results of
     operations or financial position.

            NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS
 
1. MERGER AND DISTRIBUTIONS
 
     On December 12, 1996, EPTPC (formerly Tenneco Inc.) became an indirect
subsidiary of EPG as a result of the Merger between Old Tenneco and an indirect
subsidiary of EPG. Prior to the Merger, Old Tenneco and its subsidiaries
effected various intercompany transfers and distributions which restructured,
divided and separated their businesses, assets and liabilities so that all the
assets, liabilities and operations related to the Industrial Business and the
Shipbuilding Business were spun-off to Old Tenneco's then existing common
stockholders in the Distributions. The entity consisting of the Industrial
Business was subsequently renamed Tenneco Inc. (referred to herein as "New
Tenneco") and the entity consisting of the Shipbuilding Business was renamed
Newport News. Following the Distributions, the remaining operations consisted
primarily of those operations related to the transmission and marketing of
natural gas and the discontinued operations of Old Tenneco. Pursuant to the
Merger, Old Tenneco was renamed EPTPC. As a result of the Merger, EPG indirectly
owns 100 percent of the common stock of EPTPC, representing at the effective
time of the Merger approximately 75 percent of the equity value of EPTPC; the
balance of the equity value of EPTPC is held by the holders of its Series A
Preferred Stock, which was issued in a registered public offering in November
1996 and remains outstanding.
 
     As used in these financial statements, unless the context otherwise
requires, the "Company" refers to: (i) for periods as of and subsequent to the
Merger, EPTPC and consolidated subsidiaries; and (ii) for periods prior to the
Merger, the combined historical businesses and operations of Old Tenneco owned
directly or indirectly by EPTPC (the "Energy Businesses of EPTPC"), principally
the energy businesses and certain discontinued operations of Old Tenneco. See
also "Basis of Presentation" discussion below.
 
     In preparation for the Merger and Distributions, Old Tenneco initiated the
Debt Realignment. As part of the Debt Realignment, Old Tenneco initiated tender
offers for certain issues of the Company's debt and certain other debt issues
were exchanged into New Tenneco debt, defeased or otherwise retired. Upon
completion of the debt realignment transactions, the Company is only responsible
for the remaining debt which was not tendered, exchanged, defeased or otherwise
retired. The Company recognized an after-tax extraordinary charge of $234
million related to the Debt Realignment immediately prior to the Merger.
 
     At December 31, 1996, EPTPC had approximately $1.6 billion of borrowings
under the Credit Facility dated as of November 4, 1996. In addition, the Company
had $300 million ($296 million net book value) of Series A Preferred Stock
outstanding and $134 million aggregate principal amount of debt which was not
redeemed or retired as a part of the Debt Realignment. Borrowings under the
Credit Facility are guaranteed by EPG. The primary assets of EPTPC consist of
its investment in TGP, which holds the majority of the Company's operations, and
management anticipates that the funds necessary to service the debt and other
securities of EPTPC will be provided by EPG or the operations and asset sale or
financing transactions of TGP.
 
     On October 30, 1996, the IRS issued a private letter ruling to Old Tenneco,
in which the IRS ruled that for U.S. federal income tax purposes: (i) the
Distributions would be tax-free to Old Tenneco and, except to the extent cash
was received in lieu of fractional shares, to its then existing stockholders;
(ii) the Merger would constitute a tax-free reorganization; and (iii) that
certain other transactions effected in connection with the Merger and
Distributions would be tax-free. If the Distributions were not to qualify as
tax-free distributions, then a corporate level federal income tax would be
assessed to the consolidated group of which Old Tenneco was previously the
common parent. This corporate level federal income tax would be payable by
EPTPC. Under certain limited circumstances, however, New Tenneco and Newport
News. have agreed to indemnify EPTPC for a defined portion of such tax
liabilities.
 
     The consideration provided in the Merger was approximately $4 billion,
including retained debt and EPG equity consideration valued at $913 million.

  Accounting for Acquisition by EPG
 
     The acquisition of the Company by EPG pursuant to the Merger has been
accounted for using the purchase method of accounting and included the
application of "pushdown" accounting to the Company's financial statements
effective as of December 31, 1996. Accordingly, an allocation of the purchase
price has been assigned to the assets and liabilities acquired based upon the
estimated fair value of those assets and liabilities as of the acquisition date.
A substantial portion of the excess purchase price, approximately $1.6 billion,
has been allocated to the property, plant and equipment of the Company's
interstate pipeline systems. Such allocation is based on the Company's internal
evaluation of such assets. An independent appraisal of the fair value of the
property acquired is in process and is expected to be completed by mid-1997.
Should the independent appraisal not support such allocation, the excess of
total purchase price over fair value of net assets acquired will be reflected as
goodwill. In addition, the Company may make adjustments during 1997 to other
components of the preliminary purchase price allocation relating to regulatory,
tax, environmental or other issues based upon any changes in the Company's
preliminary assumptions or analysis. The final results of the independent
appraisal and the ultimate disposition of the purchase price allocation should
not materially impact future operating results. Current FERC policy does not
permit the Company to recover through its rates amounts allocated in purchase
accounting to its regulated operations in excess of original cost.
 
     The consolidated balance sheet of EPTPC and subsidiaries as of December 31,
1996, contained herein reflects the purchase price recorded by EPG and is
referred to herein as "Post-Acquisition". The combined financial statements of
the Company for periods prior to December 31, 1996, are referred to as
"Pre-Acquisition". As a result of the change in the basis of accounting from
historical cost to reflect EPG's purchase cost, the financial statements for
Pre-Acquisition periods are not comparable to those of Post-Acquisition periods.

  Pro Forma Information
 
     The following unaudited pro forma information illustrates the effect of the
Merger and related transactions as if they had occurred at the beginning of
1995, after giving effect to certain pro forma adjustments including the
realignment of the Company's indebtedness, the issuance of the Series A
Preferred Stock, the removal of the results of the Company's exploration and
production business, and other adjustments based on the purchase price
allocation related to the acquisition, together with estimates of the related
income tax effects.

  Basis of Presentation
 
     Although the separation of the Industrial Business and Shipbuilding
Business from Old Tenneco prior to the Merger was structured as a "spin-off" of
New Tenneco and Newport News for legal, tax and other reasons, New Tenneco
succeeded to certain important aspects of the Old Tenneco business, organization
and affairs, namely: (i) New Tenneco was renamed "Tenneco Inc." subsequent to
the consummation of the Merger; (ii) New Tenneco is headquartered at Old
Tenneco's former headquarters in Greenwich, Connecticut; (iii) New Tenneco's
Board of Directors consists of those persons previously constituting the Old
Tenneco Board of Directors prior to the Merger; (iv) New Tenneco's executive
management consists substantially of
 
                                       27
<PAGE>   31
 
the Old Tenneco executive management prior to the Merger; and (v) the businesses
conducted by New Tenneco consist largely of the Industrial Business, which
represented over half of the assets, revenues and operating income of the
businesses, operations and companies constituting Old Tenneco and its
subsidiaries prior to the Merger and Distributions. In New Tenneco's Annual
Report on Form 10-K for the year ended December 31, 1996, New Tenneco has
reflected in its financial statements the historical results of operations and
financial position of the Company and the Shipbuilding Business as discontinued
operations.
 
     Consequently, the Company has restated its historical financial statements
for periods prior to
December 31, 1996 to reflect the combined financial position, results of
operations and cash flows of the Energy Businesses of EPTPC. Additionally,
certain reclassifications have been made to the prior year financial statements
to conform to current year presentation.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Control and Consolidation
 
     As a result of the Merger, EPG owns 100 percent of the common equity of
EPTPC, representing at the effective time of the Merger approximately 75 percent
of the equity value of EPTPC; the balance of the equity value of EPTPC is held
by the holders of the Series A Preferred Stock that was issued in a registered
public offering in November 1996 and remains outstanding.
 
     Investments in 20 percent to 50 percent owned companies where the Company
has the ability to exert significant influence over operating and financial
policies are accounted for by the equity method. Reference is made to Note 12,
"Investment in Affiliated Companies," for information concerning significant
equity method investments.
 
     All significant transactions and balances among combined and consolidated
businesses have been eliminated.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues
and expenses and disclosure of contingent assets and liabilities at the date of
the financial statements. Actual results could differ from those estimates.
 
  Accounting for Regulated Operations
 
     The Company's businesses that are subject to the regulations and accounting
requirements of FERC continue to meet the accounting requirements of SFAS No.
71, Accounting for the Effects of Certain Types of Regulation, which accounting
methods may differ from those used by non-regulated entities. Transactions that
have been recorded differently as a result of regulatory accounting requirements
include: transition costs to be recovered under volumetric surcharges; certain
benefits and other costs and taxes included in or expected to be included in
future rates, including costs to refinance debt. When the accounting method
followed is prescribed by or allowed by the regulatory authority for rate-making
purposes, such accounting conforms to the generally accepted accounting
principle of matching costs against the revenues to which they apply.
 
     Changes in the regulatory and economic environment may, at some point in
the future, create circumstances in which the application of regulatory
accounting principles will no longer be appropriate. If these accounting
principles should no longer be applied, an amount would be charged to earnings
as an extraordinary item. At December 31, 1996, this amount, after consideration
of purchase accounting adjustments, was estimated to be approximately $59
million, net of income taxes. Any potential charge would be non-cash and would
have no direct effect on the regulated companies' ability to seek recovery of
the underlying deferred costs in their future rate proceedings or on their
ability to include such costs in the rates set thereby.
 
                                       28
<PAGE>   32
 
  Cash and Temporary Cash Investments
 
     Short-term investments purchased with an original maturity of three months
or less are considered cash equivalents.
 
  Allowance for Doubtful Accounts and Notes
 
     The Company has established a provision for losses on accounts and notes
receivable, as well as gas imbalances due from shippers and operators, which may
become uncollectible. Collectibility is reviewed regularly, and the allowance
for bad debts is adjusted as necessary primarily under the specific
identification method. The balances of this provision at December 31, 1996 and
1995 were $45 million and $49 million, respectively.
 
  Gas Imbalances
 
     The Company values gas imbalances due to or due from shippers and operators
at the appropriate index price. The gas imbalances are either settled in cash or
made up in-kind.
 
  Inventory
 
     Inventories, consisting of materials and supplies and gas in storage, are
valued at the lower of cost, determined using the average cost method, or
market, as adjusted at December 31, 1996 for purchase accounting considerations
as discussed in Note 1, "Merger and Distributions."
 
  Property, Plant and Equipment
 
     Property, plant and equipment is recorded at cost, adjusted at December 31,
1996 to reflect the allocation of the excess purchase price as discussed in Note
1, "Merger and Distributions." Included in the Company's property, plant, and
equipment is construction work in progress of approximately $110 million and
$223 million at December 31, 1996, and 1995, respectively. An allowance for both
debt and equity funds used during construction is included in the cost of the
Company's property, plant, and equipment.
 
     Depreciation of the Company's regulated transmission facilities are
provided primarily using the composite method over the estimated useful lives of
the depreciable facilities. The rates for depreciation range from approximately
2 percent to 5 percent.
 
     Depreciation of the Company's nonregulated properties is provided using the
straight line or composite method which, in the opinion of management, is
adequate to allocate the cost of properties over their estimated useful lives.
 
     Costs of regulated properties that are not operating units, as defined by
FERC, which are retired, sold, or abandoned are charged or credited, net of
salvage, to accumulated depreciation and amortization. Gains or losses on sales
of operating units are credited or charged to income.
 
     The Company evaluates impairment of its property, plant, and equipment in
accordance with SFAS No. 121.
 
  Goodwill
 
     Goodwill resulting from acquisitions was being amortized over 20 to 40
years using the straight-line method. Such amortization amounted to $1.6 million
in 1996 and $1.8 million for 1995 and 1994, respectively. Accumulated
amortization of goodwill was $5.4 million at December 31, 1995. The pre-Merger
balance of unamortized goodwill was eliminated as part of the purchase
accounting adjustments discussed in Note 1, "Merger and Distributions."
 
                                       29

  Environmental Costs
 
     Expenditures for ongoing compliance with environmental regulations that
relate to current operations are expensed or capitalized as appropriate.
Expenditures that relate to an existing condition caused by past operations, and
which do not contribute to current or future revenue generation, are expensed.
Liabilities are recorded when environmental assessments indicate that remedial
efforts are probable and the costs can be reasonably estimated. Estimates of the
liability are based upon currently available facts, existing technology and
presently enacted laws and regulations taking into consideration the likely
effects of inflation and other societal and economic factors. All available
evidence is considered including prior experience in remediation of contaminated
sites, other companies' clean-up experience and data released by the EPA or
other organizations. These estimated liabilities are subject to revision in
future periods based on actual costs or new circumstances. These liabilities are
included in the accompanying balance sheets at their undiscounted amounts, as
adjusted through purchase accounting at December 31, 1996. Reference is made to
Note 1, "Merger and Distributions." Recoveries are evaluated separately from the
liability and, when recovery is assured, are recorded and reported separately
from the associated liability in the consolidated and combined financial
statements as a regulatory asset.
 
  Other Income
 
     Gains or losses on the sale by a subsidiary of its stock are included in
the accompanying combined statements of income when recognized.
 
  Financial Instruments With Off-Balance-Sheet Risk
 
     The Company is a party to financial instruments with off-balance-sheet risk
in the normal course of business to reduce its exposure to fluctuations in
interest rates and the price of certain energy and power commodities. These
financial instruments include interest rate swaps, price swap agreements,
futures, and options.
 
     Price risks management activities consist of transactions entered into by
the Company to hedge the impact of market fluctuations on assets, liabilities,
production or other contractual commitments. Changes in the market value of
these transactions are deferred until the gains or losses on the hedged item are
recognized. See Note 4 for further discussion of the Company's price risk
management activities.
 
  Income Taxes
 
     The Company accounts for income taxes whereby it recognizes deferred tax
assets and liabilities for the future tax consequences of temporary differences
between the tax basis of assets and liabilities and their reported amounts in
the consolidated and combined financial statements. Deferred tax assets are
reduced by a valuation allowance when, based upon management's estimates, it is
more likely than not that a portion of the deferred tax assets will not be
realized in a future period. The estimates utilized in the recognition of
deferred tax assets are subject to revision in future periods based on new facts
or circumstances.
 
     Old Tenneco, together with certain of its subsidiaries which were owned 80
percent or more, including subsidiaries in the Industrial Business (now held by
New Tenneco) and the Shipbuilding Business (now held by Newport News), had
entered into an agreement to file a consolidated U.S. federal income tax return.
Such agreement provided, among other things, that (i) each company in a taxable
income position would be currently charged with an amount equivalent to its
federal income tax computed on a separate return basis, and (ii) each company in
a tax loss position would be reimbursed currently to the extent its deductions,
including general business credits, were utilized in the consolidated return.
Management believes that income tax amounts reflected in the combined financial
statements of the Company prior to the Merger under the provisions of the tax
sharing arrangement would not be materially different from the income taxes
which would have been provided had the Company filed a separate consolidated tax
return. Under the tax sharing agreement, Old Tenneco paid all federal taxes
directly and billed or refunded, as applicable, its subsidiaries for the
applicable portion of the total tax payments. This tax sharing agreement remains
in effect among EPTPC

and certain of its subsidiaries which are owned 80 percent or more. EPTPC will
continue to file a separate consolidated U.S. federal income tax return
subsequent to the Merger.
 
     As a result of the Merger, the Company entered into a new tax sharing
agreement with Newport News, New Tenneco and EPG. This new tax sharing agreement
provides, among other things, for the allocation among the parties of tax assets
and liabilities arising prior to, as a result of, and subsequent to the
Distributions. Generally, EPTPC will be liable for taxes imposed on the Company.
In the case of federal income taxes imposed with respect to periods prior to the
consummation of the Distributions on the combined activities of Old Tenneco and
other members of its consolidated group prior to giving effect to the
Distributions, New Tenneco and Newport News will be liable to the Company for
federal income taxes attributable to their activities, and each will be
allocated an agreed-upon share of estimated tax payments made by Old Tenneco.
Pursuant to the new tax sharing agreement, the Company will pay New Tenneco for
the tax benefits realized from the deduction of taxable losses generated by a
debt realignment completed prior to the Merger and such amount has been accrued
in the accompanying consolidated balance sheet.
 
  Recent Pronouncements
 
     In March 1995, the Financial Accounting Standards Board issued SFAS No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of, which establishes new accounting standards for the
impairment of long-lived assets and for long-lived assets to be disposed of. The
Company adopted the new standard in the first quarter of 1996 with no material
effect on the Company's financial position or results of operations.
 
     In June 1996, the Financial Accounting Standards Board issued SFAS No. 125,
Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities, which establishes new accounting and reporting standards for
transfers and servicing of financial assets and extinguishment of liabilities.
The statement is effective for transactions occurring after December 31, 1996,
but in December 1996, the Financial Accounting Standards Board issued SFAS No.
127, Deferral of the Effective Date of Certain Provisions of FASB Statement No.
125, which defers the implementation of certain provisions of SFAS No. 125 until
January 1998. The new pronouncements are not expected to have a material impact
on the Company's financial position or results of operations.
 
     In October 1996, the American Institute of Certified Public Accountants
issued Statement of Position No. 96-1, "Environmental Remediation Liabilities,"
which establishes new accounting and reporting standards for the recognition and
disclosure of environmental remediation liabilities. The provisions of the
statement are effective for fiscal years beginning after December 15, 1996. This
pronouncement is not expected to have a material impact on the Company's
financial position or results of operations.
 
     In March 1997, SFAS No. 128, Earnings Per Share, and SFAS No. 129,
Disclosures of Information about Capital Structure, were issued. The Company is
currently evaluating the impact of these pronouncements.
 
3. LONG-TERM DEBT AND OTHER FINANCING
 
     In contemplation of the Merger and Distributions, Old Tenneco initiated a
Debt Realignment to restructure, realign, and divide the Company's indebtedness.
As part of this Debt Realignment, Old Tenneco completed certain cash tender
offers for approximately $1.5 billion aggregate principal amount of the
Company's outstanding notes and debentures. In addition, approximately $1.9
billion aggregate principal amount of Old Tenneco notes and debentures were
exchanged into notes and debentures of New Tenneco. Certain other components of
the Company's historical short-term and long-term debt were defeased, redeemed
or otherwise retired in the Debt Realignment. The cash funding requirements of
the Debt Realignment were financed with internally generated cash, new
borrowings under the Credit Facility, cash contributions from New Tenneco and
Newport News, and proceeds from the issuance of the Series A Preferred Stock.
All obligations relating to the Series A Preferred Stock, all borrowings under
the Credit Facility, and the other remaining debt of the Company, including debt
which was not tendered or exchanged in the Debt Realignment, has been retained
by the Company subsequent to the Merger. Restrictive covenants
 
                                       31

on the Company's remaining debt which was subject to the Debt Realignment were
eliminated as a part of the Debt Realignment transactions. The Company
recognized an after-tax extraordinary charge of $234 million (net of $126
million income tax benefit) related to the Company's debt realignment
immediately prior to the Merger.
 
     Subsequent to the Merger, the majority of the Company's debt consists of
borrowings under the Credit Facility and the notes and debentures that were not
tendered or exchanged pursuant to the Debt Realignment. The long-term and
short-term debt amounts at December 31, 1995, presented in the accompanying
balance sheet represent the historical indebtedness of the Company, the majority
of which was subject to the debt realignment, and includes a reduction for the
amount of corporate debt allocated to the Industrial Business and the
Shipbuilding Business. See Note 15 for information concerning debt allocated to
the Industrial Business and the Shipbuilding Business. The long-term debt
amounts at December 31, 1996 have been adjusted to fair market value in the
application of purchase accounting, as discussed in Note 1, "Merger and
Distributions."
 
     Long-term debt outstanding at December 31, 1996 and 1995, consisted of the
following:

     In November 1996, Old Tenneco established with a group of banks a 364-day
revolving credit and competitive advance facility (previously defined as the
"Credit Facility") with an initial termination date in November 1997.
Outstanding borrowings under the Credit Facility which are unpaid at the initial
termination date become due by the second anniversary following that date. Under
the Credit Facility, the banks initially agreed to make up to $3 billion of
credit available to EPTPC, which amount had been reduced by EPTPC to $2 billion
at December 31, 1996. At such date approximately $1.6 billion in borrowings and
$400 million in unused loan commitments remained outstanding under the Credit
Facility. Borrowings under the Credit Facility are guaranteed by EPG, and EPTPC
is required to pay commitment fees on the unused loan commitments under the
Credit Facility. In March 1997, TGP issued $900 million of long-term debt, with
interest rates ranging from 7 percent to 7 5/8 percent and maturities ranging
from 20 to 40 years. The proceeds of this borrowing were be used to pay down
borrowings under the Credit Facility. Due to the refinancing of the Credit
Facility borrowings with long-term debt of TGP, the Company has classified $900
million of borrowings at December 31, 1996 under that facility as long-term
debt.

4. FINANCIAL INSTRUMENTS
 
  Fair Value of Financial Instruments
 
     The following disclosure of the estimated fair value of financial
instruments is presented in accordance with the requirements of SFAS No. 107.
The estimated fair value amounts have been determined by the Company using
available market information and valuation methodologies.
 
     As of December 31, 1996, and 1995, the carrying amounts of certain
financial instruments employed by the Company, including cash, temporary cash
investments, short-term borrowings and investments, and trade receivables and
payables are representative of fair value because of the short-term maturity of
these instruments. The fair value of the long-term debt has been estimated based
on quoted market prices for the same or similar issues. The fair value of all
derivative financial instruments is the estimated amount at which management
believes they could be liquidated over a reasonable period of time, based on
quoted market prices, current market conditions, or other estimates obtained
from third-party dealers.
 
     At December 31, 1996, the Company's aggregate customer and long-term
receivables balance was concentrated within the energy industry. Consequently,
the Company's credit risk could be effected by changes in the condition of the
energy industry. At December 31, 1995, the Company's aggregate customer and
long-term receivable balance was concentrated by industry as follows: energy
industry 22 percent; automotive parts industry 9 percent; packaging industry 8
percent; and farm and construction equipment industries 52 percent; all other
amounts were not significant. Receivables in the automotive parts, packaging and
farm and construction equipment industries resulted from Tenneco Credit
Corporation's (renamed El Paso Energy Credit Corporation) financing of
receivables of current and former operating divisions of Old Tenneco. See Note
15 for a further discussion.

  Derivative
 
     Interest Rate Swaps -- The fair value of interest rate swaps was based on
the cost that would have been incurred to buy out those swaps in a loss position
and the consideration that would have been received to terminate those swaps in
a gain position. At December 31, 1996 all outstanding interest rate swaps had
fully matured. At December 31, 1995, the Company was a party to swaps with a
notional value of $1.5 billion, $750 million of which were in a net receivable
position and $795 million of which were in a net payable position. Notional
amounts associated with these swaps do not represent future cash payment
requirements. These contractual amounts are only used as a base to measure
amounts to be exchanged at specified settlement dates. The counterparties to
these interest rate swaps were major international financial institutions. The
risk associated with counterparty default on interest rate swaps were measured
as the cost of replacing, at the prevailing market rates, those contracts in a
gain position.
 
     Price Risk Management -- The Company uses exchange-traded futures and
option contracts and over-the-counter option and swap contracts to reduce its
exposure to fluctuations in the prices of natural gas. The fair value of these
contracts is based upon the estimated consideration that would be received to
terminate those contracts in a gain position and the estimated cost that would
be incurred to terminate those contracts in a loss position. As of December 31,
1996 and 1995, these contracts, maturing through 2000 and 1997, respectively,
had an absolute notional contract quantity of 237 Bcf and 321 Bcf, respectively.
Since the contracts described above are designated as hedges whose fair values
correlate to price movements of natural gas, any gains or losses on the
contracts resulting from market changes will be offset by losses or gains on the
hedged transactions. The Company has off-balance sheet risk of credit loss in
the event of non-performance by counterparties to all over-the-counter
contracts. However, the Company does not anticipate non-performance by the
counterparties.

  Non-derivative
 
     Guarantees -- At December 31, 1996 and 1995, the Company had guaranteed
payment and performance of approximately $3 million and $14 million,
respectively, primarily with respect to letters of credit and other guarantees
supporting various financing and operating activities.
 
5. COMMITMENTS AND CONTINGENCIES
 
  Rates and Regulatory Matters
 
     In 1992, FERC issued Order No. 636 which restructured the natural gas
industry by requiring mandatory "unbundling" of pipeline sales and
transportation services. Numerous parties appealed to the Court of Appeals,
challenging the legality of Order No. 636 generally, as well as the legality of
specific provisions of Order No. 636. In July 1996, the Court of Appeals issued
its decision upholding, in large part, Order No. 636, and remanded to FERC
several issues for further explanation, including further explanation of FERC's
decision to allow pipelines to recover 100 percent of their GSR costs and FERC's
requirement that pipelines allocate 10 percent of GSR costs to interruptible
transportation customers. In February 1997, FERC reaffirmed its decision to
allow pipelines to recover 100 percent of GSR costs. In addition, FERC modified
the requirement that pipelines allocate 10 percent of GSR costs to interruptible
customers to permit pipelines to propose an allocation of any percentage of such
costs to their interruptible customers.
 
     TGP implemented revisions to its tariff, which restructured its
transportation, storage and sales services to convert TGP from primarily a
merchant to primarily a transporter of gas as required by Order No. 636. As a
result of this restructuring, TGP's gas sales declined while certain obligations
to producers under long-term gas supply contracts continued, causing TGP to
incur significant restructuring transition costs. Pursuant to the provisions of
Order No. 636 allowing for the recovery of transition costs related to the
restructuring, TGP has made filings to recover the following transition costs:
(i) costs related to its Bastian Bay facilities; (ii) the "stranded" costs of
TGP's continuing contractual obligations to pay for capacity on other pipeline
systems ("TBO costs"); (iii) GSR costs resulting from TGP's remaining gas
purchase obligations (collectively referred to as "Transition Costs"); and (iv)
the remaining unrecovered balance of purchased gas ("PGA") costs. The filings
implementing TGP's recovery mechanisms for these transition costs were accepted
by FERC effective September 1, 1993, subject to refund and pending FERC review
and approval for eligibility and prudence.
 
     TGP's filings to recover costs related to its Bastian Bay facilities have
been rejected by FERC based on the continued use of the gas production from the
field; however, FERC recognized the ability of TGP to file for the recovery of
any losses upon disposition of these assets. TGP has filed for appellate review
of FERC actions and is confident that the Bastian Bay costs will ultimately be
recovered; FERC has not contested the ultimate recoverability of these costs.
 
     TGP is recovering through a surcharge, subject to refund, TBO costs
formerly incurred to perform its sales function. FERC issued an order requiring
TGP to refund certain of these costs and refunds were made in May 1996. TGP is
appealing this decision and believes such appeal will likely be successful.
 
     A phased proceeding was scheduled at FERC with respect to the recovery of
TGP's GSR costs. Testimony has been completed in connection with Phase I of that
proceeding relating to the eligibility of GSR cost recovery. Phase II of the
proceeding on the prudency of the costs to be recovered and on certain contract
specific eligibility issues has not yet been scheduled. Although the Order No.
636 transition cost recovery mechanism provides for complete recovery by
pipelines of eligible and prudently incurred transition costs, certain customers
have challenged the prudence and eligibility of TGP's GSR costs and settlement
discussions have been entered into with TGP's customers concerning the amount of
such costs in response to FERC's public statements encouraging such settlements.
 
     On February 28, 1997, TGP filed with FERC a proposed settlement of all
issues related to the recovery by TGP of its Transition Costs and related
proceedings, as discussed above. Upon final approval by FERC, this settlement
will become effective retroactive to January 1, 1997. The settlement is based
upon the preliminary GSR understanding, which called for sharing of transition
costs, that EPG reached with TGP's
 
                                       36
<PAGE>   40
 
customers in October 1996 in anticipation of the Merger. The GSR Stipulation and
Agreement allows for TGP to recover up to $770 million in Transition Costs,
including interest, of which approximately $531 million has previously been
recovered, subject to refund, pending resolution of the Transition Costs issues.
Assuming FERC approves the GSR Stipulation and Agreement, TGP will be entitled
to recover additional Transition Costs, up to the remaining $239 million,
through a two-year demand transportation surcharge and an interruptible
transportation surcharge. The terms of the GSR Stipulation and Agreement provide
for a rate case moratorium through November 2000 (subject to certain limited
exceptions) and provide a rate cap, indexed to inflation, through October 31,
2005, for certain of TGP's customers. The purchase accounting adjustments
reflected in the Company's consolidated financial statements assume approval of
the settlement with respect to TGP's Transition Costs in accordance with the
terms of the GSR Stipulation and Agreement.
 
     Although parties to TGP's Transition Cost proceedings do not have to
declare their support or opposition to the GSR Stipulation and Agreement until
mid-March, management believes that all of TGP's customers will support or not
oppose the GSR Stipulation and Agreement.
 
     Following negotiations with its customers, TGP filed in July 1994 with FERC
a Stipulation and Agreement (the "PGA Stipulation"), which provides for the
recovery of PGA costs of approximately $100 million and the recovery of costs
associated with the transfer of storage gas inventory to new storage customers
in TGP's restructuring proceeding. The PGA Stipulation eliminates all challenges
to the PGA costs, but establishes a cap on the charges that may be imposed upon
former sales customers. In April 1995, FERC orders approving the PGA Stipulation
and resolving all outstanding issues became final. TGP implemented the terms of
the PGA Stipulation and made refunds in May 1995. The refunds had no material
effect on the Company's reported net income. The orders approving the PGA
Stipulation have been appealed to the Court of Appeals by certain customers. TGP
believes the FERC orders approving the PGA Stipulation will be upheld on appeal.
 
     In order to resolve litigation concerning purchases made by TGP of
synthetic gas produced from the Great Plains coal gasification plant, TGP, along
with three other pipelines, executed four separate settlement agreements with
Dakota and the U.S. Department of Energy and initiated four separate proceedings
at FERC seeking approval to implement the settlement agreements. Among other
things, the settlement required TGP to pay Dakota over a limited period a
premium over the spot price for Dakota's production and resolves the litigation
with Dakota. As of December 31, 1996, TGP had paid $87 million of this premium
obligation and has accrued its estimated remaining premium obligation through
December 2003 of $55 million. FERC previously ruled that the costs related to
the Great Plains project are eligible for recovery through GSR and other special
recovery mechanisms and that the costs are eligible for recovery for the
duration of the term of the original gas purchase agreements. In October 1994,
FERC consolidated the four proceedings and set them for hearing before an ALJ.
The hearing, which concluded in July 1995, was limited to the issue of whether
the settlement agreements are prudent. The ALJ concluded, in his initial
decision issued in December 1995, that the settlement was not prudent. In
December 1996, FERC unanimously reversed that decision and upheld the
settlements among the pipelines, the U.S. Department of Energy and Dakota. No
parties filed for rehearing of the FERC decision. TGP notified Dakota in
December 1996 that it accepted the settlement.
 
     In December 1994, TGP filed the 1995 Rate Case. In January 1995, FERC
accepted the filing, suspended its effectiveness for the maximum period of five
months pursuant to normal regulatory process, and set the matter for hearing. On
July 1, 1995, TGP began collecting rates, subject to refund, reflecting an $87
million increase in TGP's annual revenue requirement. A Stipulation was filed
with an ALJ in this proceeding in April 1996. This Stipulation resolves the
rates that are the subject of the 1995 Rate Case, including a structural rate
design change that results in a larger proportion of TGP's transportation
revenues being dependent upon throughput. Under the Stipulation, TGP is required
to refund, upon final approval of the Stipulation, the difference between the
revenues collected under the July 1, 1995 motion rates and the revenues that
would have been collected pursuant to the rates underlying the Stipulation. In
October 1996, FERC approved the Stipulation with certain modifications and
clarifications which are not material. In January 1997, FERC issued an order
denying request for rehearing of the October 1996 order. Refunds will be made in
March 1997. The Company has established a provision for these refunds, and the
balance of this
 
                                       37
<PAGE>   41
 
provision at December 31, 1996 was $167 million. One party to the rate
proceeding, a competitor of TGP, filed with the Court of Appeals a Petition for
Review of the FERC orders approving the Stipulation.
 
     Management believes the ultimate resolution of the aforementioned rate and
regulatory matters, which are in various stages of finalization, will not have a
materially adverse effect on the Company's financial position or results of
operations.
 
  Environmental Matters
 
     As of December 31, 1996, the Company had a reserve of approximately $187
million to cover environmental assessments and remediation activities as
discussed below. The reserve for such issues at December 31, 1996 has been
adjusted to reflect the purchase price allocation discussed in Note 1,
"Merger and Distributions."
 
     Since 1988, TGP has been engaged in an internal project to identify and
deal with the presence of PCBs and other substances of concern, including
substances on the EPA List of Hazardous Substances at compressor stations and
other facilities operated by both its interstate and intrastate natural gas
pipeline systems. While conducting this project, TGP has been in frequent
contact with federal and state regulatory agencies, both through informal
negotiation and formal entry of consent orders, in order to assure that its
efforts meet regulatory requirements.
 
     Due to the current uncertainty regarding the further activity necessary for
TGP to address the presence of PCBs, substances on the EPA List of Hazardous
Substances and other substances of concern on its sites, including the
requirements for additional site characterization, the actual amount of such
substances at the sites, and the final, site-specific cleanup decisions to be
made with respect to cleanup levels and remediation technologies, the Company
cannot at this time accurately project what additional costs, if any, may arise
from future characterization and remediation activities. While there are still
many uncertainties relating to the ultimate costs which may be incurred, based
upon the Company's evaluation and experience to date, the Company believes that
the recorded estimate for the reserve is adequate.
 
     Following negotiations with its customers, TGP in May 1995 filed with FERC
a separate Stipulation and Agreement (the "Environmental Stipulation") that
establishes a mechanism for recovering a substantial portion of the
environmental costs. In November 1995, FERC issued an order approving the
Environmental Stipulation. Although one shipper filed for rehearing, FERC denied
rehearing of its order in February 1996. This shipper filed a Petition for
Review in April 1996 in the Court of Appeals; TGP believes the FERC order
approving the Environmental Stipulation will be upheld on appeal. The
Environmental Stipulation, which was effective July 1, 1995, had no material
effect on the Company's financial position or results of operations. As of
December 31, 1996, the balance of the regulatory asset was $49 million.
 
     TGP has completed settlements with and has received payments from the
majority of its liability insurance policy carriers for remediation costs and
related claims. TGP believes that additional recoveries from the remaining
carriers in the pending litigation against such carriers are reasonably
possible. In addition, TGP has settled its pending litigation against and
received payment from the manufacturer of the
PCB-containing lubricant previously used in the starting air systems in a
portion of TGP's pipeline. TGP has reduced the amount it is seeking to recover
under the Environmental Stipulation by the amount it has received in these
proceedings.
 
     The Company and certain of its subsidiaries have been designated, have
received notice that they could be designated, or have been asked for
information to determine whether they could be designated as a PRP with respect
to 25 sites under the Comprehensive Environmental Response, Compensation and
Liability Act (CERCLA or Superfund) or state equivalents. The Company has sought
to resolve its liability as a PRP with respect to these Superfund sites through
indemnification by third parties and/or settlements which provide for payment of
the Company's allocable share of remediation costs. Because the clean-up costs
are estimates and are subject to revision as more information becomes available
about the extent of remediation required, the
 
                                       38
<PAGE>   42
 
Company's estimate of its share of remediation costs could change. Moreover,
liability under the federal Superfund statute is joint and several, meaning that
the Company could be required to pay in excess of its pro rata share of
remediation costs. The Company's understanding of the financial strength of
other PRPs has been considered, where appropriate, in its determination of its
estimated liability as described herein. The Company presently believes that the
costs associated with the current status of such entities as PRPs at the
Superfund sites referenced above will not have a materially adverse effect on
the financial position or results of operations of the Company.
 
     In addition, the Company has identified a number of formerly owned or
leased sites, and certain other sites associated with its discontinued
operations, where environmental remediation may be required. The Company
presently believes that the costs to remediate these sites will not have a
materially adverse effect on its financial position or results of operations.
 
     The Company has identified other sites where environmental remediation may
be required should there be a change in ownership, operations or applicable
regulations. These possibilities cannot be predicted or quantified at this time
and, accordingly, no provision has been recorded. However, provisions have been
made for all instances where it has been determined that the incurrence of any
material remedial expense is probable. The Company believes that the provisions
recorded for environmental exposures are adequate based on current estimates.
 
  Capital Commitments
 
     At December 31, 1996, the Company had capital or investment commitments of
$36 million which are expected to be funded through cash provided by operations
and/or incremental borrowings. The Company's other planned capital and
investment projects are discretionary in nature, with no substantial capital
commitments made in advance of the actual expenditures.
 
  Purchase Obligations
 
     In connection with the financing commitments of certain joint ventures, the
Company has entered into unconditional purchase obligations for products and
services of $121 million ($94 million on a present value basis) at December 31,
1996. The Company's annual obligations under these agreements are $22 million
for the years 1997 and 1998, $21 million for the years 1999 and 2000, and $11
million for the year 2001. Payments under such obligations, including additional
purchases in excess of contractual obligations, were $25 million, $26 million
and $34 million for the years 1996, 1995 and 1994, respectively. In addition, in
connection with the Great Plains coal gasification project, TGP continues to
have an obligation to purchase 30 percent of a capped volume of the plant output
through July 2009. TGP has executed a settlement of this contract as a part of
its GSR negotiations discussed in "Rates and Regulatory Matters" above and has
established a provision for the estimated costs in excess of market prices which
management believes is adequate.

6. ACQUISITIONS AND DISPOSITIONS
 
  Acquisitions
 
     During 1995, the Company acquired the natural gas pipeline assets of PASA
which includes a 488-mile pipeline, for approximately $225 million. Also during
1995, the Company acquired a 50 percent interest in two gas-fired cogeneration
plants from ARK Energy, a privately owned power generation company, for
approximately $65 million.
 
                                       39
<PAGE>   43
 
     In May 1996, the Company acquired a 50 percent ownership interest in a
producing gas field (approximately 500 Bcf) and a 47.5 percent ownership
interest in a 135 MW power generating plant under construction in South
Sulawesi, Indonesia.
 
     In September 1996, the Company reacquired for $41 million the 20 percent
interest in the Company's marketing and intrastate pipeline subsidiary.
 
     Each of the acquisitions discussed above was accounted for as a purchase.
Net income would not have been significantly different from amounts reported if
the acquisitions had occurred at the beginning of each respective year.
 
  Disposition of Assets
 
     In 1994, the Company's marketing and intrastate pipeline subsidiary issued
50 shares of its common stock, diluting Old Tenneco's ownership in this
subsidiary to 80 percent and resulting in a gain of $23 million. No taxes were
provided on the gain because management expected that the recorded investment
would be recovered in a tax-free manner.
 
     In December 1995, the Company sold its 50 percent interest in Kern River
for a pre-tax gain of $30 million. Kern River owns a 904-mile pipeline extending
from Wyoming to California. Also in 1995, the Company sold certain other
facilities and assets for a combined pre-tax loss of $19 million.
 
     During 1996, TGP sold its 13.2 percent interest in Iroquois, its 50 percent
interest in Dauphin Island Gathering System and certain other assets, resulting
in a net pre-tax gain of $35 million.
 
     In December 1996, subsequent to the Merger, the Company sold 70 percent of
its interests in two natural gas pipeline systems in Australia to CNGI Australia
Pty. Limited, a wholly-owned indirect subsidiary of Consolidated Natural Gas
Company, and four Australian investors for approximately $400 million, inclusive
of related debt financing involving these projects, and completed the sale of
its oil and gas exploration, production and financing unit, formerly known as
Tenneco Ventures, in a $105 million transaction. There was no gain or loss
recognized on these transactions due to the Merger and the application of
pushdown accounting to the Company. The net proceeds from these transactions
were utilized to retire outstanding borrowings under the Credit Facility
subsequent to year end.

     As reflected by the valuation allowance in the table above, the Company had
potential tax benefits of $117 million at December 31, 1995, which were not
recognized in the combined statements of income when generated. These benefits
resulted primarily from U.S. capital loss carryforwards which were available to
offset future capital gains. During 1996, these capital loss carryforwards were
utilized to offset taxes on capital gain transactions of the Company and certain
Old Tenneco affiliates. The table above reflects the deferred tax effects of the
purchase price allocation at December 31, 1996, as discussed in Note 1, "Merger
and Distributions."

8. EMPLOYEE BENEFITS
 
  Postretirement Benefits
 
     As part of the Distributions and Merger, the Company assumed responsibility
for certain benefits for former employees of Old Tenneco and the postretirement
health care plans for the Company's employees were significantly changed. The
Company will be responsible for benefits for both the Company's former employees
and former employees of operations previously disposed of by Old Tenneco.
Employees who retire before July 1, 1997 will receive the same benefits as
former employees. While employees who retire on or after July 1, 1997 will
continue to receive $10,000 of postretirement life insurance, they will not
receive any employer subsidized postretirement health care benefits. All of
these benefits may be subject to deductibles, co-payment provisions and other
limitations. The Company has reserved the right to change these benefits.
 
     The majority of the Company's postretirement benefit plans are not funded.
In June 1994, two trusts were established to fund postretirement benefits for
certain plan participants of TGP. The contributions are collected from customers
in FERC approved rates. As of December 31, 1996, cumulative contributions were
$16 million. Plan assets consist principally of fixed income securities.
 
     The funded status of the postretirement benefit plans reconciles with
amounts recognized on the consolidated and combined balance sheets at December
31, 1996 and 1995, as follows:

Note: The accrued postretirement benefit cost has been recorded based upon
      certain actuarial estimates, which are subject to revision in future
      periods given new facts or circumstances, as described below, and reflects
      adjustments recorded in purchase accounting at December 31, 1996. For the
      1996 period the plan liabilities were estimated as of December 31, 1996
      and for the 1995 period the plan liabilities were estimated at September
      30, 1995 and rolled forward to December 31, 1995.
 
     In December 1992, FERC issued a statement of policy which allows
jurisdictional pipelines to recognize allowances for prudently incurred costs of
postretirement benefits other than pensions on an accrual basis consistent with
the accounting principles set forth in SFAS No. 106. The Company believes that
all costs of providing postretirement benefits to its employees are necessary
and prudent operating expenses and that such costs are recoverable in rates.
Accordingly, postretirement benefit costs related to FERC regulated operations
have been deferred as a regulatory asset. At December 31, 1996 the balance of
this regulatory asset was $28 million and is being recovered through rates.

</TABLE>
 
     The initial weighted average assumed health care cost trend rate used in
determining the 1996, 1995 and 1994 accumulated postretirement benefit
obligation was 6 percent, 7 percent and 8 percent, respectively, declining to 5
percent in 1997 and remaining at that level thereafter.
 
     Increasing the assumed health care cost trend rate by one percentage-point
in each year would increase the 1996, 1995 and 1994 accumulated postretirement
benefit obligations by approximately $5 million, $14 million and $14 million,
respectively, and would increase the aggregate of the service cost and interest
cost components of the net postretirement benefit cost for 1996, 1995 and 1994
by approximately $1 million, $1 million and $3 million, respectively.
 
     The discount rates (which are based on long-term market rates) used in
determining the 1996, 1995 and 1994 accumulated postretirement benefit
obligations were 7.75 percent, 7.75 percent and 8.25 percent, respectively.
 
  Pension Plans
 
     In conjunction with the Distributions in December 1996, benefit accruals
for Company employees in the Old Tenneco Retirement Plan (the "TRP") were frozen
as of the last day of December 1996 and all benefits were fully vested. New
Tenneco became the sole sponsor of the TRP such that the Company is not
responsible for any benefits accrued before the last day of December 1996. The
Company employees became participants in the new EPG Cash Balance Pension Plan
("CBP Select") as of January 1, 1997 with no account balances credited for prior
service.
 
     The Company's employees who were age 55 with at least 10 years of service
as of December 31, 1996 are eligible for special benefits under the 1997 Early
Retirement Incentive Program (the "ERIP") under the CBP Select. As a result of
the Merger, certain eligible employees who elected to retire under the ERIP will
receive an enhanced credit under the CBP Select which will be one year of pay
for most employees. The Company has accrued for these enhanced benefits as of
December 31, 1996.
 
9. PREFERRED STOCK
 
     At December 31, 1996, EPTPC had authorized 20,000,000 shares of preferred
stock. In November 1996, the Company issued 6,000,000 shares of Series A
Preferred Stock. The Series A Preferred Stock is not convertible into shares of
any other class or series of stock of the Company and it has no maturity date.
Holders of shares of Series A Preferred Stock are entitled to receive cash
dividends payable quarterly at the rate of 8 1/4% of the stated value of $50 per
share. It is not redeemable at the option of EPTPC prior to December 31, 2001,
unless one or more amendments to the Internal Revenue Code are enacted that
reduce the percentage of the dividends received deduction as specified in
Section 243(a)(1) of the Internal Revenue Code. On or after December 31, 2001,
the Series A Preferred Stock is redeemable at the option of the Company, in
whole or in part, upon not less than 30 days' notice at a redemption price of
$50 per share, plus unpaid dividends.
 
     In December 1996, the remaining outstanding shares of the $7.40 and $4.50
preferred stock issues of Old Tenneco were exchanged for EPG equity and
cancelled in accordance with the terms of the Merger. The $7.40 and $4.50
preferred stock issues had a mandatory redemption value of $100 per share and
were recorded
 
                                       43
<PAGE>   47
 
at their fair value at the date of original issue (an aggregate of $250 million)
with periodic accretions of the excess of the redemption value over the fair
value at the date of issue.
 
     In March 1997, the Company issued 3,036,600 shares of a new series of
preferred stock (the "Series B Preferred Stock"), which is subordinated to the
Series A Preferred Stock, to EPG in exchange for cancellation of indebtedness
owed to EPG of approximately $152 million. EPG is entitled to receive
cash dividends payable annually at the rate of 8 1/2% of the stated value of $50
per share. On or after
December 31, 2001, the Series B Preferred Stock is redeemable at the option of
the Company, in whole or in part, upon not less than 30 days' notice at a
redemption price of $50 per share, plus unpaid dividends.

12. INVESTMENT IN AFFILIATED COMPANIES
 
     The Company holds investments in various affiliates which are accounted for
on the equity method of accounting. The principal equity method investments were
the Company's investments in international

<PAGE>   48
 
pipelines, interstate pipelines, power generation plants, gathering systems and
natural gas storage facilities. These investments were subject to certain
purchase accounting adjustments at December 31, 1996, as discussed in Note 1,
"Merger and Distributions."
 
     At December 31, 1996 and 1995, the Company's consolidated stockholders'
equity and combined equity, respectively, included equity in undistributed
earnings from equity method investments of $12 million and $25 million,
respectively. Dividends and distributions received from affiliates accounted for
on the equity method were $43 million, $53 million and $48 million during 1996,
1995 and 1994, respectively.
 
     At December 31, 1996, the Company's investment in affiliates balance
exceeded the underlying net assets of its investments by $69 million. The excess
is being amortized into income by decreasing equity in net income of affiliated
companies using the straight-line method over the estimated economic useful
life.
 
     Summarized financial information of the Company's proportionate share of 50
percent or less owned companies accounted for by the equity method of accounting
as of December 31, 1996, 1995 and 1994, and for the years then ended is as
follows:

NOTE: Balance sheet amounts related to Kern River are not included in the table
      above as of December 31, 1996 and 1995, due to the Company's sale of its
      investment in Kern River in December 1995. Reference is made to Note 6 for
      information concerning the sale of Kern River.
 
13. NATURE OF OPERATIONS AND SIGNIFICANT CUSTOMERS
 
     The Company is engaged in the transportation, gathering, processing and
marketing of natural gas. For the year ended December 31, 1996, the Company's
operating revenues were predominately derived from the transportation and
marketing of natural gas. The Company's principal end markets for the
transportation of natural gas are the Northeast and Midwest United States. Prior
to the Merger, Tenneco Credit Corporation (now renamed El Paso Energy Credit
Corporation), a Company subsidiary, was engaged in financing, on a nonrecourse
basis, receivables of other operating divisions of Old Tenneco. El Paso Energy
Credit Corporation continues to sell certain energy receivables in the ordinary
course of its business subsequent to the Merger.
 
     The Company did not have gross revenues from any customer equal to, or in
excess of, 10 percent of the combined operating revenues for the years ended
December 31, 1996, 1995, and 1994.

15. TRANSACTIONS WITH AFFILIATES
 
  Combined Equity
 
     The "Combined Equity" caption in the accompanying combined financial
statements represents Old Tenneco's cumulative investment in the combined
businesses of the Company prior to the Merger. Changes in the "Combined Equity"
caption represent the net income (loss) of the Company, cash paid for interest
allocated to affiliates, net of tax, changes in corporate debt allocated to
affiliates, contributions from (distributions to) Old Tenneco stockholders, and
net cash and noncash contributions from (distributions to) affiliates. Reference
is made to the statements of changes in consolidated stockholders' equity and
combined equity for an analysis of activity in the "Pre-Acquisition Combined
Equity" caption for each of the three years in the period ended December 31,
1996.
 
  General and Administrative Expenses
 
     Included in the total general and administrative expenses for 1996, 1995
and 1994, is $17 million, $16 million, and $13 million, respectively, which
represents the Company's share of Old Tenneco's corporate general and
administrative costs for legal, financial, communication and other
administrative services. Old Tenneco's corporate general and administrative
expenses have been allocated based on the estimated level of effort devoted to
Old Tenneco's various operations and relative size based on revenues, gross
property and payroll. The Company's management believes the method for
allocating corporate general and administrative expenses is reasonable and that
total general and administrative expenses reflected in the accompanying
pre-acquisition combined statements of income are reasonable when compared with
the total general and administrative costs the Company would have incurred on a
stand-alone basis.
 
  Corporate Debt and Interest Allocations
 
     The Company's historical practice has been to incur indebtedness for its
consolidated group at the parent company level or at a limited number of
subsidiaries rather than at the operating company level, and to centrally manage
various cash functions. Consequently, corporate debt of the Company and its
related interest expense have been allocated to Old Tenneco's automotive,
packaging, and shipbuilding businesses ("Old Tenneco's non-energy operations")
based upon the portion of Old Tenneco's investment in Old Tenneco's non-energy
operations that is deemed to be debt, generally based upon the ratio of Old
Tenneco's non-energy operations' net assets to Old Tenneco's consolidated net
assets plus debt. Interest expense was allocated at a rate equivalent to the
weighted-average cost of all corporate debt, which was 8.2 percent, 7.7 percent
and 8.3 percent for 1996, 1995 and 1994, respectively. Total pre-tax interest
expense allocated to Old Tenneco's non-energy operations in 1996, 1995 and 1994
was $211 million, $180 million and $120 million, respectively. Old Tenneco's
non-energy operations have also been allocated tax benefits totaling
approximately 35 percent of the allocated pre-tax interest expense. Although
interest expense, and the related tax effects, have been allocated to Old
Tenneco's non-energy operations for financial reporting on a historical basis,
Old Tenneco's non-energy operations have not been billed for these amounts. The
changes in allocated corporate debt and the after-tax allocated interest expense
have been included as a component of the Company's combined equity. Although
management believes that the historical allocation of corporate debt and
interest expense is reasonable, it is not necessarily indicative of the debt
currently borrowed by the Company or the debt which the Company may incur in the
future.
 
  Notes and Advances Receivable or Payable with Affiliates
 
     "Cash contributions from (distributions to) affiliates" in the statements
of changes in consolidated stockholders' equity and combined equity consist of
net cash changes in notes and advances receivable or payable between the Company
and the Industrial Business and Shipbuilding Business which have been included
in combined equity. Historically, Old Tenneco has utilized notes and advances to
centrally manage cash funding requirements for its consolidated group.
 
     At December 31, 1995, the Company had an interest-bearing note payable to
the Industrial Business totaling $494 million, which was due on demand and
included as a component of the Company's combined
 
                                       46
<PAGE>   50
 
equity. At December 31, 1995, the Company had a non-interest bearing note
payable to the Shipbuilding Business totaling $965 million, which is included as
a component of the Company's combined equity. The unpaid balances of all notes
and advances between the Company, the Industrial Business and the Shipbuilding
Business were capitalized and forgiven immediately prior to the Distributions.
 
     The "Note payable to affiliates" balance at December 31, 1996 relates to an
interest-bearing demand loan made to TGP from EPG in December 1996 subsequent to
the Merger.
 
  Accounts Receivable and Accounts Payable -- Affiliated Companies
 
     The December 31, 1995 "Accounts payable -- Affiliated companies" balance
primarily includes billings for general and administrative costs incurred by the
Industrial Business and charged to the Company. The December 31, 1995 "Accounts
receivable -- Affiliated companies" balance primarily relates to billings for
U.S. income taxes incurred by Old Tenneco and charged to the Industrial Business
and Shipbuilding Business. Affiliated accounts receivable and accounts payable
between the Company and the Industrial Business and Shipbuilding Business were
settled, capitalized or converted into ordinary trade accounts, as applicable,
as part of the Distributions.
 
     The December 31, 1996 "Accounts receivable -- Affiliated companies" balance
relates to
interest-bearing advances of cash flows from TGP operations to EPG.
 
  Employee Benefits
 
     Certain employees of the Company participated in Old Tenneco's employee
stock ownership and employee stock purchase plans. The Old Tenneco employee
stock ownership plan provided for the grant of Old Tenneco common stock options
and other stock awards at a price not greater than market value at the date of
grant. The Old Tenneco employee stock purchase plan allowed employees to
purchase Old Tenneco common stock at a 15 percent discount subject to certain
thresholds. Certain employees of the Industrial Business and Shipbuilding
Business also participated in Old Tenneco's employee stock ownership and
employee stock purchase plans. The cost of stock issued to these employees was
billed to the Industrial Business and Shipbuilding Business. In connection with
the Distributions, outstanding options on Old Tenneco common stock held by the
Company's employees were vested so that they became fully exercisable prior to
the Merger. If not exercised prior to the Merger, such options were cancelled
upon consummation of the Merger. Outstanding options on Old Tenneco common stock
held by the Industrial Business and Shipbuilding Business employees were
converted into new options of New Tenneco and Newport News, as applicable, so as
to preserve the aggregate value of the options held prior to the Distributions.
 
     Employees of the Company also participated in certain Old Tenneco
postretirement and pension plans. Reference is made to Note 8, "Employee
Benefits," for a further discussion of the plans.
 
  Sales of Receivables
 
     At December 31, 1995, Tenneco Credit Corporation (now renamed El Paso
Energy Credit Corporation) had purchased $513 million of trade receivables from
Old Tenneco's Industrial Business. Tenneco Credit Corporation sold a portion of
these trade receivables to a third party in the ordinary course of business. In
addition, at December 31, 1995, Tenneco Credit Corporation had certain notes
receivable primarily related to retail sales of farm and construction equipment
by Case Corporation which it received in a prior transaction. As a part of the
intercompany transfers preceding the Merger and Distributions, Tenneco Credit
Corporation transferred these Case Corporation retail receivables and all of its
interest and obligations associated with receivables relating to the Industrial
Business held or factored at that time to New Tenneco.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To El Paso Tennessee Pipeline Co.:
 
     We have audited the accompanying post-acquisition balance sheet of El Paso
Tennessee Pipeline Co. ("EPTPC") and consolidated subsidiaries as of December
31, 1996 and the pre-acquisition combined balance sheet of the Energy Businesses
of EPTPC, as predecessor operations to EPTPC and consolidated subsidiaries (see
Note 1), as of December 31, 1995, and the related pre-acquisition combined
statements of income, cash flows and changes in consolidated stockholders'
equity and combined equity for each of the three years in the period ended
December 31, 1996. These consolidated and combined financial statements, and the
schedule referred to below, are the responsibility of EPTPC's management. Our
responsibility is to express an opinion on these consolidated and combined
financial statements and schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated and combined financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the consolidated
and combined financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall consolidated and combined financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
     In our opinion, the consolidated and combined financial statements referred
to above present fairly, in all material respects, the post-acquisition
financial position of EPTPC and consolidated subsidiaries as of December 31,
1996 and the pre-acquisition combined financial position of the Energy
Businesses of EPTPC as of December 31, 1995, and the results of their
pre-acquisition combined operations and cash flows for each of the three years
in the period ended December 31, 1996, in conformity with generally accepted
accounting principles.
 
     Our audits were made for the purpose of forming an opinion on the basic
consolidated and combined financial statements taken as a whole. The
supplemental schedule listed in the index to Part IV, Item 14 is presented for
purposes of complying with the Securities and Exchange Commission's rules and is
not part of the basic consolidated and combined financial statements. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic consolidated and combined financial statements and, in
our opinion, fairly states in all material respects the financial data required
to be set forth therein in relation to the basic consolidated and combined
financial statements taken as a whole.

                 If any such adjustment to the annual dividend rate occurs
         after a Dividend Payment Date as to which the Corporation previously
         paid dividends on the Series A Preferred Stock, additional dividends
         will be payable, out of funds legally available therefor, on each
         share of Series A Preferred Stock on the next succeeding Dividend
         Payment Date (or if such adjustment occurs after the dividend payable
         on the next succeeding Dividend Payment Date has been declared, on the
         second succeeding Dividend Payment Date following the date of such
         adjustment) to the holder of record of such share of Series A
         Preferred Stock as of the record date established for such succeeding
         Dividend Payment Date (or second succeeding Dividend Payment Date, as
         the case may be) in an amount equal to the excess of (x) the aggregate
         amount of dividends that would have been payable on such share on all
         Dividend Payments as to which the Corporation previously paid
         dividends on the Series A Preferred Stock if dividends had accrued
         from the date of issuance of the Series A Preferred Stock at the
         adjusted annual dividend rate, over (y) the aggregate amount of
         dividends actually paid with respect to such share of Series A
         Preferred Stock. If the annual dividend rate is adjusted as provided
         above, the Corporation will cause notice of such adjustment to be sent
         to the holders of record of the Series A Preferred Stock as they
         appear in the stock register of the Corporation.

                 Section 2. Changes in the Dividends Received Percentage. (a)
         Notwithstanding Section 1 hereof, if one or more amendments to the
         Internal Revenue Code of 1986, as amended (the "Code"), are enacted
         that reduce the percentage of the dividends received deduction as
         specified in Section 243(a)(1) of the Code or any successor provision
         (the "Dividends Received Percentage") to below 70%, the amount of each
         dividend payable per share of the Series A Preferred Stock for
         dividend payments made on or after the effective date of such change
         (or the second succeeding dividend payment after such effective date,
         as herein described) will be adjusted by multiplying the amount of the
         dividend payable pursuant to Section 1 (before adjustment pursuant to
         this Section 2) by a factor, which will be the number determined in
         accordance with the following formula (the "DRD Formula"), and
         rounding the result to the nearest cent:

                              1 - (.35(1 - .70))
                            ------------------------
                              1 - (.35(1 - DRP))
                                                                 
                 For the purposes of the DRD Formula, "DRP" means the Dividends
         Received Percentage applicable to the dividend in question. No
         amendments to the Code, other than a change in the percentage of the
         dividends received deduction set forth in Section 243 (a)(1) of the
         Code or any successor provision, will give rise to an adjustment.
         Notwithstanding the foregoing provisions of this Section 2, in the
         event that, with respect to any such amendment, the Corporation
         receives either an unqualified opinion of nationally


                                       2
<PAGE>   10
         recognized independent tax counsel selected by the Corporation or a
         private letter ruling or similar form of authorization from the
         Internal Revenue Service to the effect that such an amendment would
         not apply to dividends payable on the Series A Preferred Stock, then
         any such amendment will not result in the adjustment provided for
         pursuant to the DRD Formula. The opinion referenced in the previous
         sentence must be based upon a specific exception in the legislation
         amending the DRP or upon a published pronouncement of the Internal
         Revenue Service addressing such legislation. The Corporation's
         calculation of the dividends payable, as so adjusted and as certified
         accurate as to calculation and reasonable as to method by the
         independent public accountants then regularly engaged by the
         Corporation, will be final and not subject to review absent manifest
         error.
        
                 (b) If any amendment to the Code which reduces the Dividends
         Received Percentage to below 70% is enacted after a dividend payable
         on Dividend Payment Date has been declared but prior to the applicable
         Dividend Payment Date, the amount of dividend payable on such Dividend
         Payment Date will not be increased. Instead, an amount, equal to the
         excess of (x) the product of the dividends paid by the Corporation on
         such Dividend Payment Date and the factor derived from the DRD Formula
         (where the DRP used in the DRD Formula would be equal to the reduced
         Dividends Received Percentage for such dividends), over (y) the
         dividends paid by the Corporation on such Dividend Payment Date, will
         be payable, out of funds legally available therefor, to holders of
         record as of the record date established for the next succeeding
         Dividend Payment Date in addition to any other amounts payable on such
         date. Notwithstanding the foregoing, no such additional dividend will
         be payable pursuant to this Section 2 if the such amendment to the
         Code would not result in an adjustment to the DRD Formula due to the
         Corporation having received either an opinion of counsel or tax ruling
         referred to in paragraph (a) of this Section 2.

                 (c) If, prior to March 31, 1997, an amendment to the Code is
         enacted that reduces the Dividends Received Percentage to below 70%
         and such reduction retroactively applies to a Dividend Payment Date as
         to which the Corporation previously paid dividends on the Series A
         Preferred Stock (each an "Affected Dividend Payment Date"), additional
         dividends (the "Additional DRD Dividends") will be payable out of
         funds legally available therefor on the succeeding Dividend Payment
         Date (or if such amendment is enacted after the dividend payable on
         such Dividend Payment Date has been declared, on the second succeeding
         Dividend Payment Date following the date of enactment) to holders of
         record as of the record date established for such succeeding Dividend
         Payment Date (or second succeeding Dividend Payment Date, as the case
         my be) in an amount equal to the excess of (x) the product of the
         dividends paid by the Corporation on each Affected Dividend Payment
         Date and the factor derived from the DRD Formula (where the DRP used
         in the DRD Formula would be equal to the reduced Dividends Received
         Percentage applied to each Affected Dividend Payment Date), over (y)
         the dividends paid by the Corporation on all Affected Dividend Payment
         Dates.

                 (d) Additional DRD Dividends will not be payable in respect to
         the enactment of any amendment to the Code on or after March 31, 1997
         which retroactively reduces the Dividends Received Percentage to below
         70%, or if enacted prior to March 31, 1997, which would not result in
         an adjustment due to the Corporation having received either an opinion
         of counsel or tax ruling referred to in paragraph (a) of this Section
         2. The Corporation shall only be required to make one payment of
         Additional DRD Dividends.

                 (e) In the event that the amount of dividends payable per
         share of the Series A Preferred Stock are adjusted pursuant to the DRD
         Formula and/or Additional DRD Dividends are to be paid, the
         Corporation shall cause notice of each such adjustment and, if
         applicable, any Additional DRD Dividends to be sent to the holders of
         record of the Series A Preferred Stock as they appear in the stock
         register of the Corporation.

                 Section 3. Optional Redemption. (a) At any time or from time
         to time, on or after December 31, 2001, the Series A Preferred Stock
         may be redeemed at the option of the Corporation, in whole or in part,
         out of funds legally available therefor, at a redemption price equal
         to $50.00 per share plus an amount equal to accrued and unpaid
         dividends (whether or not declared) to but excluding the date fixed
         for redemption including any changes in dividends payable due to
         changes in the annual dividend rate or Dividends Received Percentage,
         and Additional DRD dividends, if any. In addition to any restrictions
         or limitations


                                      3
<PAGE>   11
         contained in the Certificate of Incorporation, if any, if full
         cumulative dividends on the Series A Preferred Stock for all past
         dividend periods have not been paid or declared and set apart for
         payment, the Series A Preferred Stock may be redeemed only in full
         (but not in party) by the Corporation pursuant to this paragraph (a)
         and the Corporation shall not purchase or acquire any shares of Series
         A Preferred Stock other than pursuant to Section 4 hereof or pursuant
         to a purchase or exchange offer made on the same terms to all holders
         of the Series A Preferred Stock. If fewer than all the outstanding
         shares of Series A Preferred Stock are to be redeemed, the Corporation
         will select those to be redeemed pro rata, by lot or by a
         substantially equivalent method.

                 (b) If the Dividends Received Percentage is equal to or less
         than 40% and, as a result, the amount of dividends on the Series A
         Preferred Stock payable on any Dividend Payment Date will be or is
         adjusted upwards as provided in Section 2, the Corporation, at its
         option, may redeem all, but not less than all, of the outstanding
         shares of the Series A Preferred Stock, out of funds legally available
         therefor, provided that within 60 days of the date on which an
         amendment to the Code is enacted which reduces the Dividends Received
         Percentage to 40% or less, the Corporation gives notice of redemption
         as provided in paragraph (d) of this Section 3 to all holders of
         record of the Series A Preferred Stock. A redemption of the Series A
         Preferred Stock in accordance with this paragraph (b) shall be at the
         applicable redemption price set forth in the following table, in each
         case plus an amount equal to accrued and unpaid dividends (whether or
         not declared) thereon to but excluding the date fixed for redemption,
         including any changes in dividends payable due to changes in the
         annual dividend rate or Dividends Received Percentage, and Additional
         DRD Dividends, if any:

                 of the stockholders of the Corporation entitled to vote thereon
                 on or prior to March 31, 1997; or (iii) the Corporation shall

         such may be amended, supplemented or modified from time to time) among
         the Corporation, New Tenneco Inc., a newly formed wholly-owned
         subsidiary of the Corporation ("New Tenneco"), and Newport News
         Shipbuilding Inc., a wholly-owned subsidiary of the Corporation
         ("Newport News"), undertake various intercompany transfers and
         distributions designed to restructure, divide and separate their
         various businesses and assets so that all of the assets, liabilities
         and operations of (A) their automotive parts, packaging and
         administrative services businesses ("Industrial Business") are owned
         and operated by New Tenneco, and (B) their shipbuilding business
         ("Shipbuilding Business") are owned and operated by Newport News; (ii)
         the Corporation will then distribute pro rata to holders of the common
         stock of the Corporation all of the outstanding common stock of New
         Tenneco and Newport News; and (iii) thereafter a subsidiary of El Paso
         will merge with and into the Corporation, which will then consists of
         the remaining existing and discontinued operations of the Corporation
         and its subsidiaries other than those relating to the Industrial
         Business or the Shipbuilding Business, including the transmission and
         marketing of natural gas, pursuant to the Merger Agreement.

                 Notice of redemption pursuant to this Section 4 will be given
         by mail, not less than 30 nor more than 60 days prior to the Mandatory
         Redemption Date to each record holder of shares of Series A Preferred
         Stock at the address of such holder in the stock register of the
         Corporation. If a notice of redemption has been given, from and after
         the Mandatory Redemption Date (unless the Corporation defaults in
         making payment of the redemption price), dividends on the Series A
         Preferred Stock will cease to accrue, such shares will no longer be
         deemed to be outstanding, and all rights of the holders thereof as
         stockholders of the Corporation (except the right to receive the
         redemption price) will cease. Subject to applicable escheat and
         similar abandoned property laws, and moneys set aside by the
         Corporation for such redemption and unclaimed at the end six months
         from the Mandatory Redemption Date shall revert to the general funds


                                      5

         of the Corporation, after which reversion the holders of such shares
         so called for redemption shall look only to the general funds of the
         Corporation for the payment of the amounts payable upon such
         redemption. Any interest accrued on funds so deposited shall be paid
         to the Corporation from time to time.

                 Section 5. Voting. The Series A Preferred Stock shall not have
         any voting rights except as required by law or the Certificate of
         Incorporation, or as hereinafter set forth:

                          (a) Each share of Series A Preferred Stock shall
                 entitle the holder thereof to one vote on all matters
                 submitted to a vote of the holders of Series A Preferred
                 Stock.

                          (b) The holders of Series A Preferred Stock, voting
                 as separate series from all other series of Junior Preferred
                 Stock and classes of capital stock, shall be entitled, at each
                 annual meeting of stockholders of the Corporation, to elect a
                 number of directors of the Corporation equivalent to the
                 smallest number representing at least one-sixth of the number
                 of members of the Board of Directors as if there were no
                 vacancies or unfilled newly created directorships on such
                 Board, without giving effect to any directorships created or
                 directors elected pursuant to paragraph (c) below. Any
                 director so elected shall hold office until the next annual
                 meeting and until his or her successor shall be elected and
                 qualify, subject, however, to prior death, resignation,
                 retirement, disqualification or removal from office. So long
                 as any shares of Series A Preferred Stock are outstanding, the
                 number of members of the Board of Directors of the Corporation
                 (as if there were no vacancies or unfilled newly created
                 directorships on such Board, without giving effect to any
                 directorships created or directors elected pursuant to
                 paragraph (c) below) shall be set at an integral multiple of
                 six.

                          A director elected pursuant to the terms of this
                 paragraph (b) may be removed without cause only by the holders
                 of a majority in voting power of the outstanding Series A
                 Preferred Stock.

                          At such time as all shares of the Series A Preferred
                 Stock shall cease to be outstanding, the term of office of any
                 director elected pursuant to this paragraph (b), or his or her
                 successor, shall automatically terminate.

                          (c) Whenever, at any time or times, dividends payable
                 on the Series A Preferred Stock shall be in arrears for
                 dividend periods, whether or not consecutive, containing in
                 the aggregate a number days equivalent to six calendar
                 quarters, the holders of outstanding Series A Preferred Stock
                 shall have the exclusive right, in addition to the rights
                 under (b) above, voting as a separate series from all other
                 series of Junior Preferred Stock and classes of capital stock
                 of the Corporation, at each meeting of the stockholders held
                 for the purpose of electing directors, to elect two directors
                 of the Corporation, until such time as all dividends
                 accumulated on the Series A Preferred Stock and in arrears
                 shall have been paid in full or declared and set apart for
                 payment, at which time the right of the holders of the Series
                 A Preferred Stock to vote pursuant to the provisions of this
                 paragraph (c) shall terminate, subject to revesting in the
                 event of each and every subsequent default of the character
                 and for the time above mentioned.

                          At any time when voting rights shall, pursuant to the
                 provisions of this paragraph (c), be vested in the Series A
                 Preferred Stock, the number of directors of the Corporation
                 shall be automatically increased, to the extent necessary, so
                 that two directors may be elected by the holders of the Series
                 A Preferred Stock and a proper officer of the Corporation
                 shall, upon the written request of the holders of record of at
                 least ten percent in aggregate liquidation value of the Series
                 A Preferred Stock then outstanding, addressed to the Secretary
                 of the Corporation, call a special meeting of holders of the
                 Series A preferred Stock. Such meeting shall be held at the
                 earliest practicable date but in no event shall a special
                 meeting be held if the annual meeting of the stock holders of
                 the Corporation is to be held within 90 days of the receipt by
                 the Secretary of the Corporation of such request. If such
                 meeting shall not be called by the proper officer of the
                 Corporation as required within 20 days after personal service
                 of the said written request upon the Secretary of the
                 Corporation, or within 20 days after mailing the same within
                 the United States of America by certified or registered mail,
                 return receipt requested,

<PAGE>   14
                 addressed to the Secretary of the Corporation at its principal
                 office (such mailing to be evidenced by the registry receipt
                 issued by the postal authorities), then the holders of record
                 of at least ten percent of the aggregate liquidation value of
                 the Series A preferred Stock then outstanding may designate in
                 writing one of their number to call such meeting, and such
                 meeting may be called by such person designated upon the
                 notice required for annual meetings of stockholders but in no
                 event shall a special meeting be held if the annual meeting of
                 stockholders of the Corporation is to be held within 90 days
                 of the receipt by the Secretary of the Corporation of such
                 request. Any holder of the Series A Preferred Stock so
                 designated shall have access to the stock books of the
                 Corporation for the purpose of causing a meeting of
                 stockholders to be called pursuant to these provisions.

                          Upon any termination of the right of the holder of
                 the Series A Preferred Stock to vote for directors as a class
                 as described in this paragraph (c), the term of office of the
                 directors so elected as described in this paragraph (c) shall
                 automatically terminate and the number of directors shall be
                 reduced accordingly.

                          (d) At any meeting so called pursuant to paragraph (c)
                 above, and at any other meeting of stockholders held for the
                 purpose of electing directors at which the holders of the
                 Series A Preferred Stock shall have the right to elect
                 directors as provided in paragraph (b) or paragraph (c) above,
                 the presence in person or by proxy of a majority in voting
                 power of the outstanding shares of the Series A Preferred
                 Stock, shall be required to constitute a quorum thereof for the
                 election of any director by the holders of the Series A
                 Preferred Stock.

                          At any such meeting or adjournment thereof, (x) the
                 absence of the required quorum of the Series A Preferred Stock
                 shall not prevent the election of directors other than those to
                 be elected by the Series A Preferred Stock and the absence of a
                 quorum for the election of such other directors shall not
                 prevent the election of the directors to be elected by the
                 Series A Preferred Stock, and (y) in the absence of either or
                 both such quorums, a majority in voting power of the holders
                 present in person or by proxy of the stock or stocks which lack
                 a quorum shall have power to adjourn the meeting, subject to
                 applicable law, for the election of directors which they are
                 entitled to elect from time to time without notice other than
                 announcement at the meeting until a quorum shall be present.

                          (e) If by reason of any resignation, retirement,
                 disqualification, death or removal there are not in office all
                 such directors that the holders of the Series A Preferred
                 Stock are entitled to elect pursuant to paragraph (c), then
                 any such vacancy shall be filled only by the remaining
                 director or directors elected by such holders or, only in the
                 event there is no such remaining director, by the holders of
                 the Series A Preferred Stock entitled to vote thereon. If by
                 reason of any resignation, retirement, disqualification, death
                 or removal there are not in office all such directors that the
                 holders of the Series A Preferred Stock are entitled to elect
                 pursuant to paragraph (b), then any such vacancy shall be
                 filled only by a majority of the remaining directors elected
                 by such holders or, in the event there are no such remaining
                 directors, by the majority vote of the remaining directors
                 then constituting the Board of Directors.

                          Promptly after the right of the holders of the Series
                 A Preferred Stock to fill any vacancy as set forth in the
                 first sentence of the immediately preceding paragraph arises,
                 the Board of Directors may cause a special meeting of the
                 holders of Series A Preferred Stock entitled to vote thereon,
                 to be held for the purpose of filling such vacancy and such
                 vacancy shall be filled at any such special meeting. Such
                 meeting shall be held at the earliest practicable date, but in
                 no event shall a special meeting be held if the annual meeting
                 of stockholders of the Corporation is to be held within 90
                 days of the occurrence of such vacancy.

                          Notwithstanding the immediately preceding paragraph,
                 at any time after the right of the holders of the Series A
                 Preferred Stock to fill any vacancy as set forth above in the
                 first sentence of the first paragraph of this paragraph (e)
                 arises, a proper officer of the Corporation shall, upon the
                 written request of the holders of record of at least ten
                 percent in aggregate liquidation value of the Series A
                 Preferred Stock then outstanding, addressed to the Secretary
                 of the Corporation, call a special meeting of holders


                                      7
<PAGE>   15
                 of the Series A Preferred Stock. Such meeting shall be held at
                 the earliest practicable date but in no event shall a special
                 meeting be held if the annual meeting stockholders of the
                 Corporation is to be held within 90 days of the occurrence of
                 such vacancy. If such meeting shall not be called by the proper
                 officer of the Corporation as required within 20 days after
                 personal service of the said written request upon the Secretary
                 of the Corporation, or within 20 days after mailing the same
                 within the United States of America by registered mail
                 addressed to the Secretary of the Corporation as its principal
                 office (such mailing to be evidenced by the registry receipt
                 issued by the postal authorities), then the holders of record
                 of at least ten percent of the aggregate liquidation value of
                 the Series A Preferred Stock then outstanding may designate in
                 writing one of their number to call such meeting, and such
                 meeting may be called by such person designated upon the notice
                 required for annual meetings of stockholders and shall be held
                 at the place at which the last preceding annual meeting of the
                 stockholders of the Corporation was held. Any holder of the
                 Series A Preferred Stock so designated shall have access to the
                 stock books of the Corporation for the purpose of causing a
                 meeting of stockholders to be called pursuant to these
                 provisions.

                          (f) In addition to any other vote or consent of
                 stockholders required by law or the Certificate of
                 Incorporation, if any, so long as any shares of Series A
                 Preferred Stock are outstanding, the Corporation shall not,
                 without the consent of the holders of at least a majority in
                 voting power of the outstanding shares of Series A Preferred
                 Stock, given in person or by proxy, either in writing or by
                 vote at annual meeting or a special meeting called for that
                 purpose:

                                  (A) issue any additional shares of Series A
                          Preferred Stock (other than the 6,000,000 shares of
                          Series A Preferred Stock authorized hereby), or issue
                          any shares of any class or series of stock ranking
                          prior to or on parity with the Series A Preferred
                          Stock as to the payment of dividends or as to the
                          distribution of assets on liquidation, dissolution or
                          winding up:

                                  (B) issue any obligations or security
                          convertible into share of stock ranking prior to or
                          on parity with the Series A Preferred Stock as to the
                          payment of dividends or as the distribution of assets
                          on liquidation, dissolution or winding up; or

                                  (C) amend the Certificate of Incorporation or
                          the Certificate of Designation if the amendment would
                          alter or change the powers, preferences or special
                          rights of the shares of Series A Preferred Stock so
                          as to affect such shares adversely.

                 Section 6. Restrictions or Dividends and Stock Repurchase.
         Subject to any additional restrictions or limitations contained in the
         Certificate of Incorporation, if any, so long as any shares of Series
         A Preferred Stock remain outstanding, unless full cumulative dividends
         on the outstanding shares of Series A Preferred Stock for all past
         dividend periods have been paid, or declared and set apart for
         payment, and the Corporation shall not be in default with respect to
         its obligations under Section 4 hereof, dividends may not be paid or
         declared and other distributions may not be made upon any class or
         series of stock of the Corporation ranking junior to or on a parity
         with the Series A Preferred Stock as to dividends or rights upon
         dissolution, liquidation or winding up the Corporation nor may any
         such class or series of stock of the Corporation be purchased,
         retired or otherwise acquired by the Corporation, in either case
         without consent, given in person or by proxy, either in writing or by
         vote at any annual meeting or as a special meeting called for that
         purpose, of the holders of at least a majority in voting power of the
         outstanding shares of Series A Preferred Stock present in person or by
         proxy at such meeting, provided that quorum, consisting of at least a
         majority in voting power of the then outstanding shares of Series A
         Preferred Stock is present; provided, however, that, notwithstanding
         the foregoing provisions of this Section 6 (but subject to any
         restrictions or limitations to the contrary contained in the
         Certificate of Incorporation), the Corporation may any time redeem,
         purchase or acquire, out of funds legally available therefor, shares
         of stock ranking junior to or on a parity with the Series A Preferred
         Stock as to dividends and rights upon liquidation, dissolution and
         winding up of the Corporation in exchange for, or out of net cash
         proceeds from a substantially concurrent sale of, other shares of any
         stock of the Corporation ranking junior to the Series A Preferred
         Stock as to dividends and rights upon liquidation, dissolution and
         winding up.

     Section 7. Ranking. (a) Any class or series of stock of the Corporation
shall be deemed to rank:

        (i) prior to the Series A Preferred Stock as to the payment of
     dividends or as to distributions of assets upon liquidation, dissolution or
     winding up, as the case may be, if the holders of such class or series 
     shall be entitled to the receipt of dividends or of amounts distributable 
     upon liquidation, dissolution or winding up, as the case may be, in 
     preference or priority to the holders of Series A Preferred Stock:

        (ii) on a parity with the Series A Preferred Stock as to the payment of
     dividends, whether or not the dividend rates or dividend payment dates 
     thereof be different from those of the Series A Preferred Stock, if the 
     holders of such class or series of stock and the holders of the Series A 
     Preferred Stock shall be entitled to the receipt of dividends in 
     proportion to their respective amounts of accrued and unpaid dividends 
     per share, without preference or priority one over the other, and on a 
     parity with the Series A Preferred Stock as to the distribution of assets 
     upon liquidation, dissolution or winding up, whether or not the 
     liquidation prices per share thereof be different from those of the Series
     A Preferred Stock, if the holders of such class or series of stock and the 
     holders of the Series A Preferred Stock shall be entitled to the receipt 
     of amounts distributable upon liquidation, dissolution or winding up
     in proportion to their respective liquidation preferences, without

    dividends or as to the distribution of assets upon liquidation, dissolution
    or winding up, as the case may be, if the holders of Series A Preferred 
    Stock shall be entitled to receipt of dividends or of amounts distributable
    upon liquidation, dissolution or winding up, as the case may be, in 
    preference or priority to the holders of shares of such class or series.

    (b) Except for the Common Stock, par value $5.00 per share, of the
Corporation (as such may be constituted from time to time, the "Common Stock")
and the Series A Participating Junior Preferred Stock, without par value, of
the Corporation (the "Participating Junior Preferred Stock"), each other class
and series of stock of the Corporation existing on the date of the adoption of
this Certificate shall be deemed to rank prior to the Series A Preferred Stock
both as to the payment of dividends and as to the distribution of assets upon
liquidation, dissolution or winding up.  The Common Stock and the Participating
Junior Preferred Stock shall be deemed to rank junior to the Series A Preferred
Stock both as to the payment of dividends and as to the distribution of assets
upon liquidation, dissolution or winding up.

        Section 8. Liquidation Rights. (a) The amount that the holders of
Series A Preferred Stock shall be entitled to receive in the event of any
dissolution, liquidation or winding up of the affairs of the Corporation,
whether voluntary or involuntary (collectively, a "Liquidation"), shall be
$50.00 per share, plus an amount equal to all accrued and unpaid dividends to
the date of Liquidation including any changes in dividends payable due to
changes in the annual dividend rate of Dividends Received Percentage, and
Additional DRD Dividends, if any, and no more.  After such amount is paid in
full, no further distributions or payments shall be made in respect of shares
of Series A Preferred Stock, such shares of Series A Preferred Stock shall no
longer be deemed to be outstanding or be entitled to any powers, preferences,
rights or privileges, including voting rights, and such shares of Series A
Preferred Stock shall be surrendered for cancellation to the Corporation.

     (b) In the event of any liquidation, dissolution or winding up of the
affairs of the Corporation, then before any distribution or payment shall be
made to the holders of any class or series of stock of the Corporation ranking
junior to the Series A Preferred Stock, the holders of the Series A Preferred
Stock (subject to the rights of the holders of any stock ranking prior to the
Series A Preferred Stock as to the rights on liquidation, dissolution and
winding up) shall be entitled to be paid in full the amounts set forth in
paragraph (a) of this Section 8. After such payment shall have been made in
full to the holders of the Series A Preferred Stock, the remaining assets and
funds of the Corporation shall be distributed among the holders of the stock of
the Corporation ranking junior in respect thereof to the Series A Preferred
Stock according to their respective rights.  In the event that the assets of
the Corporation available for distribution to holders

                                       9
<PAGE>   17
        of Series A Preferred Stock shall not be sufficient to make the 
        payment herein required to be made in full and to pay in full the
        liquidation preference on all other shares of stock of the Corporation
        ranking on a parity with the Series A Preferred Stock as to amounts 
        distributable upon dissolution, liquidation or winding up of the 
        Corporation, such assets shall be distributed to the holders of the 
        respective shares of Series A Preferred Stock and any such other 
        parity stock pro rata in proportion to the full amounts payable upon
        the shares of Series A Preferred Stock and any such other parity stock 
        if all amounts payable thereon were paid in full.

           Section 9. Maturity.  Unless otherwise redeemed as provided herein, 
        the term of the Series A Preferred Stock shall be perpetual.

                            ------------------------
 
     I, Stacy J. James, Secretary of El Paso Tennessee Pipeline Co. (hereinafter
referred to as the "Corporation"), a corporation organized and existing under
the General Corporation Law of the State of Delaware, in accordance with the
provisions of Section 151 thereof, DO HEREBY CERTIFY:
 
     That pursuant to authority conferred upon the Board of Directors by the
Certificate of Incorporation of said Corporation, as amended, the Board of
Directors, by unanimous written consent, pursuant to Section 141(f) of the
General Corporation Law of the State of Delaware, dated as of March 5, 1997,
adopted a resolution providing for the issuance of a series of Preferred Stock,
to be designated "8 1/2% Cumulative Junior Preferred Stock, Series B", which
resolution is as follows:
 
     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation by the Certificate of Incorporation of the Corporation, as
amended (as such may be further amended from time to time, the "Certificate of
Incorporation"), a series of Preferred Stock, par value $0.01 per share, of the
Corporation (the "Preferred Stock") be, and hereby is, created to be designated
"8 1/2% Cumulative Junior Preferred Stock, Series B" (hereinafter referred to as
the "Series B Preferred Stock"), consisting of 3,036,600 shares, and the
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions of the Series B Preferred Stock are
hereby fixed and stated to be as follows (all terms used herein that are defined
in the Certificate of Incorporation shall be deemed to have the meanings
provided therein):
 
     SECTION 1. Dividends. (a) The dividend rate on the Series B Preferred Stock
shall be 8 1/2% of $50 per share of Series B Preferred Stock per annum.
Dividends on shares of the Series B Preferred Stock shall accrue, whether or not
declared, on a daily basis from the date of issuance of such shares. Accrued but
unpaid dividends shall not bear interest.
 
     (b) Dividends on the Series B Preferred Stock shall be payable, when, as
and if declared by the Board of Directors of the Corporation out of assets
legally available therefor, annually on the last day of December in each year
(each, a "Dividend Payment Date"), with the first dividend payment date being
the next Dividend Payment Date following the date of issuance. Dividends on each
Dividend Payment Date will be payable to holders of record of the Series B
Preferred Stock as they appear on the stock books of the Corporation on a record
date, not more than 60 days preceding such Dividend Payment Date, fixed for such
purpose by the Board of Directors in advance of such Dividend Payment Date.
Dividends payable on the Series B Preferred Stock for any period shorter than a
year shall be computed on the basis of a 360-day year of twelve 30-day months.
The Series B Preferred Stock shall rank on a parity with each other series of
Preferred Stock as to the payment of dividends, except to the extent otherwise
provided in Section 5 hereof or in the resolution or resolutions providing for
the issuance of such other series.
 
     SECTION 2. Optional Redemption. (a) At any time or from time to time, on or
after December 31, 2001, the Series B Preferred Stock may be redeemed at the
option of the Corporation, in whole or in part, out of funds legally available
therefor, at a redemption price equal to $50.00 per share plus an amount equal
to accrued and unpaid dividends (whether or not declared) to but excluding the
date fixed for redemption. In addition to any restrictions or limitations
contained in the Certificate of Incorporation, if any, if full cumulative
dividends on the Series B Preferred Stock for all past dividend periods have not
been paid or declared and set apart for payment, the Series B Preferred Stock
may be redeemed only in full (but not in part) by the Corporation pursuant to
this paragraph (a) and the Corporation shall not purchase or acquire any shares
of Series B Preferred Stock other than pursuant to a purchase or exchange offer
made on the same terms to all holders of the Series B Preferred Stock. If fewer
than all the outstanding shares of Series B Preferred Stock
<PAGE>   26
 
are to be redeemed, the Corporation will select those to be redeemed pro rata,
by lot or by a substantially equivalent method.
 
     (b) Notice of redemption pursuant to paragraph (a) of this Section 2 will
be given by mail, not less than 30 days prior to the date fixed for redemption
thereof, to each record holder of the shares of Series B Preferred Stock to be
redeemed at the address of such holder in the stock register of the Corporation.
If a notice of redemption has been given, from and after the specified
redemption date (unless the Corporation defaults in making payment of the
redemption price), dividends on the Series B Preferred Stock so called for
redemption will cease to accrue, such shares will no longer be deemed to be
outstanding, and all rights of the holders thereof as stockholders of the
Corporation (except the right to receive the redemption price) will cease.
Subject to applicable escheat and similar abandoned property laws, any moneys
set aside by the Corporation for such redemption and unclaimed at the end of six
months from the redemption date shall revert to the general funds of the
Corporation, after which reversion the holders of such shares so called for
redemption shall look only to the general funds of the Corporation for the
payment of the amounts payable upon such redemption. Any interest accrued on
funds so deposited shall be paid to the Corporation from time to time.
 
     SECTION 3. Voting. The Series B Preferred Stock shall not have any voting
rights except as required by law or the Certificate of Incorporation, or as
hereinafter set forth:
 
          (a) Whenever, at any time or times, dividends payable on the Series B
     Preferred Stock shall be in arrears for dividend periods, whether or not
     consecutive, containing in the aggregate a number of days equivalent to six
     calendar quarters, the holders of outstanding Series B Preferred Stock
     shall have the exclusive right, voting as a separate series from all other
     series of Preferred Stock and classes of capital stock of the Corporation,
     at each meeting of the stockholders held for the purpose of electing
     directors, to elect two directors of the Corporation, until such time as
     all dividends accumulated on the Series B Preferred Stock and in arrears
     shall have been paid in full or declared and set apart for payment, at
     which time the right of the holders of the Series B Preferred Stock to vote
     pursuant to the provisions of this paragraph (a) shall terminate, subject
     to revesting in the event of each and every subsequent default of the
     character and for the time above mentioned.
 
          At any time when voting rights shall, pursuant to the provisions of
     this paragraph (a), be vested in the Series B Preferred Stock, the number
     of directors of the Corporation shall be automatically increased, to the
     extent necessary, so that two directors may be elected by the holders of
     the Series B Preferred Stock and a proper officer of the Corporation shall,
     upon the written request of the holders of record of at least ten percent
     in aggregate liquidation value of the Series B Preferred Stock then
     outstanding, addressed to the Secretary of the Corporation, call a special
     meeting of holders of the Series B Preferred Stock. Such meeting shall be
     held at the earliest practicable date but in no event shall a special
     meeting be held if the annual meeting of stockholders of the Corporation is
     to be held within 90 days of the receipt by the Secretary of the
     Corporation of such request. If such meeting shall not be called by the
     proper officer of the Corporation as required within 20 days after personal
     service of the said written request upon the Secretary of the Corporation,
     or within 20 days after mailing the same within the United States of
     America by certified or registered mail, return receipt requested,
     addressed to the Secretary of the Corporation at its principal office (such
     mailing to be evidenced by the registry receipt issued by the postal
     authorities), then the holders of record of at least ten percent in
     aggregate liquidation value of the Series B Preferred Stock then
     outstanding may designate in writing one of their number to call such
     meeting, and such meeting may be called by such person designated upon the
     notice required for annual meetings of stockholders but in no event shall a
     special meeting be held if the annual meeting of stockholders of the
     Corporation is to be held within 90 days of the receipt by the Secretary of
     the Corporation of such request. Any holder of the Series B Preferred Stock
     so designated shall have access to the stock books of the Corporation for
     the purpose of causing a meeting of stockholders to be called pursuant to
     these provisions.
 
          Upon any termination of the right of the holders of the Series B
     Preferred Stock to vote for directors as a class as described in this
     paragraph (a), the term of office of the directors so elected as described
     in
 
                                        2
<PAGE>   27
 
     this paragraph (a) shall automatically terminate and the number of
     directors shall be reduced accordingly.
 
          (b) At any meeting so called pursuant to paragraph (a) above, and at
     any other meeting of stockholders held for the purpose of electing
     directors at which the holders of the Series B Preferred Stock shall have
     the right to elect directors as provided in paragraph (a) above, the
     presence in person or by proxy of a majority in voting power of the
     outstanding shares of the Series B Preferred Stock shall be required to
     constitute a quorum thereof for the election of any director by the holders
     of the Series B Preferred Stock.
 
          At any such meeting or adjournment thereof, (x) the absence of the
     required quorum of the Series B Preferred Stock shall not prevent the
     election of directors other than those to be elected by the Series B
     Preferred Stock and the absence of a quorum for the election of such other
     directors shall not prevent the election of the directors to be elected by
     the Series B Preferred Stock, and (y) in the absence of the required quorum
     of the Series B Preferred Stock, a majority in voting power of the holders
     of Series B Preferred Stock present in person or by proxy shall have power
     to adjourn the meeting, subject to applicable law, but only with respect to
     the election of directors which they are entitled to elect from time to
     time without notice other than announcement at the meeting until a quorum
     shall be present.
 
          (c) If by reason of any resignation, retirement, disqualification,
     death or removal there are not in office all such directors that the
     holders of the Series B Preferred Stock are entitled to elect pursuant to
     paragraph (a) above, then any such vacancy shall be filled only by the
     remaining director elected by such holders or, only in the event there is
     no such remaining director, by the holders of the Series B Preferred Stock
     entitled to vote thereon.
 
          Promptly after the right of the holders of the Series B Preferred
     Stock to fill any vacancy as set forth in the immediately preceding
     paragraph arises, the Board of Directors may cause a special meeting of the
     holders of Series B Preferred Stock entitled to vote thereon to be held for
     the purpose of filling such vacancy, and such vacancy shall be filled at
     any such special meeting. Such meeting shall be held at the earliest
     practicable date, but in no event shall a special meeting be held if the
     annual meeting of stockholders of the Corporation is to be held within 90
     days of the occurrence of such vacancy.
 
          Notwithstanding the immediately preceding paragraph, at any time after
     the right of the holders of the Series B Preferred Stock to fill any
     vacancy as set forth above in the first paragraph of this paragraph (c)
     arises, a proper officer of the Corporation shall, upon the written request
     of the holders of record of at least ten percent in aggregate liquidation
     value of the Series B Preferred Stock then outstanding, addressed to the
     Secretary of the Corporation, call a special meeting of holders of the
     Series B Preferred Stock. Such meeting shall be held at the earliest
     practicable date but in no event shall a special meeting be held if the
     annual meeting of stockholders of the Corporation is to be held within 90
     days of the occurrence of such vacancy. If such meeting shall not be called
     by the proper officer of the Corporation as required within 20 days after
     personal service of the said written request upon the Secretary of the
     Corporation, or within 20 days after mailing the same within the United
     States of America by registered mail addressed to the Secretary of the
     Corporation at its principal office (such mailing to be evidenced by the
     registry receipt issued by the postal authorities), then the holders of
     record of at least ten percent in aggregate liquidation value of the Series
     B Preferred Stock then outstanding may designate in writing one of their
     number to call such meeting, and such meeting may be called by such person
     designated upon the notice required for annual meetings of stockholders and
     shall be held at the place at which the last preceding annual meeting of
     the stockholders of the Corporation was held. Any holder of the Series B
     Preferred Stock so designated shall have access to the stock books of the
     Corporation for the purpose of causing a meeting of stockholders to be
     called pursuant to these provisions.
 
     SECTION 4. Restrictions on Dividends and Stock Repurchases. Subject to any
additional restrictions or limitations contained in the Certificate of
Incorporation, if any, so long as any shares of Series B Preferred Stock remain
outstanding, unless full cumulative dividends on the outstanding shares of
Series B Preferred Stock for all past dividend periods have been paid, or
declared and set apart for payment, dividends may not be
 
                                        3
<PAGE>   28
 
paid or declared and other distributions may not be made upon any class or
series of stock of the Corporation ranking junior to or on a parity with the
Series B Preferred Stock as to dividends or rights upon dissolution, liquidation
or winding up of the Corporation nor may any such class or series of stock of
the Corporation be redeemed, purchased, retired or otherwise acquired by the
Corporation, in either case without the consent, given in person or by proxy,
either in writing or by vote at any annual meeting or at a special meeting
called for that purpose, of the holders of at least a majority in voting power
of the outstanding shares of Series B Preferred Stock present in person or by
proxy at such meeting, provided that a quorum, consisting of at least a majority
in voting power of the then outstanding shares of Series B Preferred Stock is
present; provided, however, that, notwithstanding the foregoing provisions of
this Section 4 (but subject to any restrictions or limitations to the contrary
contained in the Certificate of Incorporation), the Corporation may at any time
redeem, purchase or acquire, out of funds legally available therefor, shares of
stock ranking junior to or on a parity with the Series B Preferred Stock as to
dividends and rights upon liquidation, dissolution and winding up of the
Corporation in exchange for, or out of net cash proceeds from a substantially
concurrent sale of, other shares of any stock of the Corporation ranking junior
to the Series B Preferred Stock as to dividends and rights upon liquidation,
dissolution and winding up.
 
     SECTION 5. Ranking. (a) Any class or series of stock of the Corporation
shall be deemed to rank:
 
          (i) prior to the Series B Preferred Stock as to the payment of
     dividends or as to distributions of assets upon liquidation, dissolution or
     winding up, as the case may be, if the holders of such class or series
     shall be entitled to the receipt of dividends or of amounts distributable
     upon liquidation, dissolution or winding up, as the case may be, in
     preference or priority to the holders of Series B Preferred Stock;
 
          (ii) on a parity with the Series B Preferred Stock as to the payment
     of dividends, whether or not the dividend rates or dividend payment dates
     thereof be different from those of the Series B Preferred Stock, if the
     holders of such class or series of stock and the holders of the Series B
     Preferred Stock shall be entitled to the receipt of dividends in proportion
     to their respective amounts of accrued and unpaid dividends per share,
     without preference or priority one over the other, and on a parity with the
     Series B Preferred Stock as to the distribution of assets upon liquidation,
     dissolution or winding up, whether or not the liquidation prices per share
     thereof be different from those of the Series B Preferred Stock, if the
     holders of such class or series of stock and the holders of the Series B
     Preferred Stock shall be entitled to the receipt of amounts distributable
     upon liquidation, dissolution or winding up in proportion to their
     respective liquidation preferences, without preference or priority one over
     the other; and
 
          (iii) junior to the Series B Preferred Stock as to the payment of
     dividends or as to the distribution of assets upon liquidation, dissolution
     or winding up, as the case may be, if the holders of Series B Preferred
     Stock shall be entitled to receipt of dividends or of amounts distributable
     upon liquidation, dissolution or winding up, as the case may be, in
     preference or priority to the holders of shares of such class or series.
 
     (b) Except for the Common Stock, par value $0.01 per share, of the
Corporation (as such may be constituted from time to time, the "Common Stock"),
each other class and series of stock of the Corporation existing on the date of
the adoption of this Certificate shall be deemed to rank prior to the Series B
Preferred Stock both as to the payment of dividends and as to the distribution
of assets upon liquidation, dissolution or winding up. The Common Stock shall be
deemed to rank junior to the Series B Preferred Stock both as to the payment of
dividends and as to the distribution of assets upon liquidation, dissolution or
winding up.
 
     SECTION 6. Liquidation Rights. (a) The amount that the holders of Series B
Preferred Stock shall be entitled to receive in the event of any dissolution,
liquidation or winding up of the affairs of the Corporation, whether voluntary
or involuntary (collectively, a "Liquidation"), shall be $50.00 per share, plus
an amount equal to all accrued and unpaid dividends to the date of Liquidation,
and no more. After such amount is paid in full, no further distributions or
payments shall be made in respect of shares of Series B Preferred Stock, such
shares of Series B Preferred Stock shall no longer be deemed to be outstanding
or be entitled to any powers, preferences, rights or privileges, including any
voting rights, and certificates representing such shares of Series B Preferred
Stock shall be surrendered for cancellation to the Corporation.

     (b) In the event of any liquidation, dissolution or winding up of the
affairs of the Corporation, then, before any distribution or payment shall be
made to the holders of any class or series of stock of the Corporation ranking
junior to the Series B Preferred Stock, the holders of the Series B Preferred
Stock (subject to the rights of the holders of any stock ranking prior to the
Series B Preferred Stock as to rights on liquidation, dissolution and winding
up) shall be entitled to be paid in full the amounts set forth in paragraph (a)
of this Section 6. After such payment shall have been made in full to the
holders of the Series B Preferred Stock, the remaining assets and funds of the
Corporation shall be distributed among the holders of the stock of the
Corporation ranking junior in respect thereof to the Series B Preferred Stock
according to their respective rights. In the event that the assets of the
Corporation available for distribution to holders of Series B Preferred Stock
shall not be sufficient to make the payment herein required to be made in full
and to pay in full the liquidation preference on all other shares of stock of
the Corporation ranking on a parity with the Series B Preferred Stock as to
amounts distributable upon dissolution, liquidation or winding up of the
Corporation, such assets shall be distributed to the holders of the respective
shares of Series B Preferred Stock and any such other parity stock pro rata in
proportion to the full amounts payable upon the shares of Series B Preferred
Stock and any such other parity stock if all amounts payable thereon were paid
in full.
 
     SECTION 7. Maturity. Unless otherwise redeemed as provided herein, the term
of the Series B Preferred Stock shall be perpetual.

SECTION 1.  ANNUAL MEETINGS

     A meeting of the stockholders for the purpose of electing Directors and

meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.

     4.2  NOTICE OF ADJOURNED MEETINGS.  When a meeting is adjourned to another
time and place, notice of the adjourned meeting need not be given if the time
and place thereof are announced at the meeting at which the adjournment is
given.  If the adjournment is for more than thirty days, or if after the

the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

     4.3  WAIVER OF NOTICE

     4.3.1  Whenever any notice is required to be given to any stockholder
under the provisions of these By-laws, the Certificate of Incorporation or the
general Corporation Law of the State of Delaware, a waiver thereof in writing,
signed by the person or persons entitled to such notice, whether before or
after the time stated therein, shall be deemed equivalent to the giving of such
notice.

     4.3.2  The attendance of a stockholder at a meeting shall constitute a
waiver of notice of such meeting, except when a stockholder attends a meeting
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.

SECTION 5.  FIXING OF RECORD DATE FOR DETERMINING STOCKHOLDERS

     5.1  MEETINGS.  For the purpose of determining stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
the Board may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board, and
which record date shall not be more than sixty nor less than ten days before
the date of such meeting.  If no record date is fixed by the Board, the record
date for determining stockholders shall be at the close of business on the day
next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on





                                       2
<PAGE>   7
which the meeting is held.  A determination of stockholders of record entitled
to notice of or to vote at the meeting of stockholders shall apply to any
adjournment of the meeting; provided, however, that the Board may fix a new
record date for the adjourned meeting.

     5.2  DIVIDENDS, DISTRIBUTIONS AND OTHER RIGHTS.  For the purpose of
determining stockholders entitled to receive payment of any dividend or other
distribution or allotment of any rights or the stockholders entitled to
exercise any rights in respect of any change, conversion or exchange of stock,
or for the purpose of any other lawful action, the Board may fix a record date,
which record date shall not precede the date upon which the resolution fixing
the record date is adopted, and which record date shall be not more than sixty
days prior to such action.  If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board adopts the resolution relating thereto.

SECTION 6.  QUORUM

     A majority of the outstanding shares of stock of the corporation entitled
to vote, present in person or represented by proxy, shall constitute a quorum
at a meeting of the stockholders; provided that where a separate vote by a
class or classes or by a series of a class is required, a majority of the
outstanding shares of such class or classes or of such series of a class,
present in person or represented by proxy at the meeting, shall constitute a
quorum entitled to take action with respect to the vote on that matter.  Shares
of stock will be counted toward a quorum if they are either (i) present in
person at the meeting or (ii) represented at the meeting by a valid proxy,
whether the instrument granting such proxy is marked as casting a vote or
abstaining, is left blank or does not empower such proxy to vote with respect
to some or all matters to be voted upon at the meeting.  If less than a
majority of the outstanding shares entitled to vote are represented at a
meeting, a majority of the shares so represented may adjourn the meeting from
time to time without further notice.  If a quorum is present or represented at
a reconvened meeting following such an adjournment, any business may be
transacted that might have been transacted at the meeting as originally called.
The stockholders present at a duly organized meeting may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

SECTION 7.  ORGANIZATION

     At each meeting of the stockholders, the Chairman of the Board, or in his
absence the Chief Executive Officer, the President or the Vice Chairman of the
Board, or if all of the said officers are absent, a person designated by the
Board, the Chairman of the Board, the Chief Executive Officer, the President or
the Vice Chairman of the Board, or in the absence of such designated person, a
person elected by the holders of a majority in number of shares of stock
present in person or represented by proxy and entitled to vote, shall act as
chairman of the meeting.

     The Secretary, or in his absence or in the event he shall be presiding
over the meeting in accordance with the provisions of this Section, an
Assistant Secretary or, in the absence of the





                                       3
<PAGE>   8
Secretary and all of the Assistant Secretaries, any person appointed by the
chairman of the meeting, shall act as secretary of the meeting.

SECTION 8.  VOTING

     8.1  GENERAL PROVISIONS.  Unless otherwise provided in the Certificate of
Incorporation or a resolution of the Board creating a series of stock, at each
meeting of the stockholders, each holder of any share of any series or class of
stock entitled to vote at such meeting shall be entitled to one vote for each
share of stock having voting power in respect of each matter upon which a vote
is to be taken, standing in his name on the stock ledger of the corporation on
the record date fixed as provided in these By-laws for determining the
stockholders entitled to vote at such meeting.  In all matters other than the
election of Directors, if a quorum is present, the affirmative vote of the
majority of the shares present in person or represented by proxy at the meeting
and entitled to vote on the subject matter shall be the act of the
stockholders, unless the vote of a greater number is required by these By-laws,
the Certificate of Incorporation or the General Corporation Law of the State of
Delaware.  In determining the number of votes cast for or against a proposal,
shares abstaining from voting on a matter (including elections) will not be
treated as a vote for or against the proposal.  A non-vote by a broker will be
treated as if the broker never voted, but a non-vote by a stockholder will be
counted as a vote "for" the management's position.  Where a separate vote by a
class or classes or by a series of a class is required, if a quorum is present,
the affirmative vote of the majority of shares of such class or classes or
series of a class present in person or represented by proxy at the meeting
shall be the act of such class or classes or series of a class.  The provisions
of this Section will govern with respect to all votes of stockholders except as
otherwise provided for in these By-laws, the Certificate of Incorporation or
the General Corporation Law of the State of Delaware.

     8.2  VOTING FOR DIRECTORS.  At each election of Directors the voting shall
be by written ballot.  Directors shall be elected by a plurality of the votes
of the shares present in person or represented by proxy at the meeting and
entitled to vote on the election of Directors.

     8.3  SHARES HELD OR CONTROLLED BY THE CORPORATION.  Shares of its own
capital stock belonging to the corporation, or to another corporation if a
majority of the shares entitled to vote in the election of Directors of such
other corporation is held by the corporation, shall neither be entitled to vote
nor counted for quorum purposes.

     8.4  PROXIES.  A stockholder may vote by proxy executed in writing by the
stockholder or by his attorney-in-fact.  Such proxy shall be filed with the
Secretary of the corporation before or at the time of the meeting.  A
stockholder may revoke any proxy which is not irrevocable by attending the
meeting and voting in person or by filing an instrument in writing revoking the
proxy or another duly executed proxy bearing a later date with the Secretary of
the corporation.  A proxy shall become invalid three years after the date of
its execution, unless otherwise provided in the proxy.  A proxy with respect to
a specified meeting shall entitle the holder thereof to vote at any reconvened
meeting following adjournment of such meeting but shall not be valid after the
final adjournment thereof.





                                       4

SECTION 9.  INSPECTORS

     Prior to each meeting of stockholders, the Board shall appoint two
Inspectors who are not Directors, candidates for Directors or officers of the
corporation, who shall receive and determine the validity of proxies and the
qualifications of voters, and receive, inspect, count and report to the meeting
in writing the votes cast on all matters submitted to a vote at such meeting.
In case of failure of the Board to make such appointments or in case of failure
of any Inspector so appointed to act, the Chairman of the Board shall make such
appointment or fill such vacancies.  Each Inspector, immediately before
entering upon his duties, shall subscribe to an oath or affirmation faithfully
to execute the duties of Inspector at such meeting with strict impartiality and
according to the best of his ability.

SECTION 10.  LIST OF STOCKHOLDERS

     The Secretary or other officer or agent having charge of the stock ledger
of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote
at said meeting, arranged in alphabetical order and showing the address of each
stockholder and the number of shares of each class and series registered in the
name of each such stockholder.  Such list shall be open to the examination of
any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held, which place shall
be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held.  Such list shall also be produced and
kept at the time and place of the meeting during the whole time thereof, and
may be inspected by any stockholder who is present.  The stock ledger shall be
the only evidence as to who are the stockholders entitled to examine the stock
ledger, the list required by this section, or the books of the corporation, or
to vote in person or by proxy at any such meeting.

SECTION 11.  STOCKHOLDER PROPOSALS

     Stockholder proposals for inclusion in any proxy statement to be issued in
connection with the annual meeting of stockholders must be mailed to the
Corporate Secretary, El Paso Tennessee Pipeline Co., P. O. Box 1492, El Paso,
Texas 79978, and must be received by the Corporate Secretary at least by the
150th day preceding the annual meeting of stockholders unless the specific
deadline for stockholder proposals is set forth in the corporation's proxy
statement.

<PAGE>   10
Directors then in office fix the specific number of Directors to constitute the
Board.  At each annual meeting of stockholders a Board shall be elected by the
stockholders for a term of one year.  Each Director shall serve until his
successor is duly elected and shall qualify.

SECTION 2.  VACANCIES

     Vacancies in the Board and newly created directorships resulting from any
increase in the authorized number of Directors may be filled by a vote of the
majority of the Directors then in office, although less than a quorum, or by a
sole remaining Director, at any regular or special meeting of the Board.

SECTION 3.  RESIGNATIONS

     Any Director may resign at any time upon written notice to the Board, the
Chairman of the Board, the Chief Executive Officer, the President, the Vice
Chairman of the Board or the Secretary of the corporation.  Such resignation
shall take effect on the date of receipt of such notice or at any later time
specified therein; and the acceptance of such resignation, unless otherwise
required by the terms thereof, shall not be necessary to make it effective.
When one or more Directors shall resign effective at a future date, a majority
of the Directors then in office, including those who have resigned, shall have
power to fill such vacancy or vacancies to take effect when such resignation or
resignations shall become effective.

SECTION 4.  REMOVALS

     Any Director may be removed, with or without cause, at any special meeting
of the stockholders called for that purpose, by the affirmative vote of the
holders of a majority in number of shares of the corporation entitled to vote
for the election of such Director, and the vacancy in the Board caused by any
such removal may be filled by the stockholders at such a meeting.

SECTION 5.  PLACE OF MEETINGS; BOOKS AND RECORDS

     The Board may hold its meetings, and have an office or offices, at such
place or places within or without the State of Delaware as the Board from time

the books and records of the corporation, and offices or agencies for the
issue, transfer and registration of the capital stock of the corporation, to be
kept at such place or places outside of the State of Delaware as, from time to
time, may be designated by the Board.

SECTION 6.  ANNUAL MEETING OF THE BOARD

     The first meeting of each newly elected Board, to be known as the Annual
Meeting of the Board, for the purpose of electing officers, designating
committees and the transaction of such other business as may come before the
Board, shall be held as soon as practicable after the adjournment of the annual
meeting of stockholders, and no notice of such meeting shall be





                                       6
<PAGE>   11
necessary to the newly elected Directors, provided a quorum shall be present.
In the event such meeting is not held due to the absence of a quorum, the

given as hereinafter provided for special meetings of the Board, or as shall be
specified in a written waiver signed by all of the newly elected Directors.

SECTION 7.  REGULAR MEETINGS

     The Board shall provide for regular meetings of the Board at such times

the Chief Executive Officer, the President or the Vice Chairman of the Board
and shall be called by the Secretary on the written request of three Directors
on such notice as the person or persons calling the meeting shall deem
appropriate in the circumstances.  Notice of each such special meeting shall be
mailed to each Director or delivered to him by telephone, telegraph or any
other means of electronic communication, in each case addressed to his
residence or usual place of business, or delivered to him in person or given to
him orally.  The notice of meeting shall state the time and place of the
meeting but need not state the purpose thereof.  Whenever any notice is
required to be given to any Director under the provisions of these By-laws, the
Certificate of Incorporation or the General Corporation Law of the State of
Delaware, a waiver thereof in writing, signed by the person or persons entitled
to such notice, whether before or after the time stated therein, shall be
deemed equivalent to the giving of such notice.  Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the Board
or any committee appointed by the Board need be specified in the waiver of
notice of such meeting.  Attendance of a Director at any meeting shall
constitute a waiver of notice of such meeting except when a Director attends a
meeting for the express purpose of objecting to the transaction of any business
because the meeting was not lawfully called or convened.

SECTION 9.  QUORUM AND MANNER OF ACTING

     Except as otherwise provided by statute, the Certificate of Incorporation,
or these By-laws, the presence of a majority of the total number of Directors
shall constitute a quorum for the transaction of business at any regular or
special meeting of the Board, and the act of a majority of the Directors
present at any such meeting at which a quorum is present shall be the act of
the Board.  In the absence of a quorum, a majority of the Directors present may
adjourn the meeting, from time to time, until a quorum is present.  Notice of
any such adjourned meeting need not be given.

SECTION 10.  ORGANIZATION

     At every meeting of the Board, the Chairman of the Board or in his absence
the Chief Executive Officer, the President or the Vice Chairman of the Board,
or if all of the said officers are absent, a chairman chosen by a majority of
the Directors present shall act as chairman of the





                                       7
<PAGE>   12
meeting.  The Secretary, or in his absence, an Assistant Secretary, or in the
absence of the Secretary and all the Assistant Secretaries, any person
appointed by the chairman of the meeting, shall act as secretary of the
meeting.

SECTION 11.  CONSENT OF DIRECTORS IN LIEU OF MEETING

     Unless otherwise restricted by the Certificate of Incorporation or by
these By-laws, any action required or permitted to be taken at any meeting of
the Board, or any committee designated by the Board, may be taken without a
meeting if all members of the Board or committee consent thereto in writing,
and such written consent is filed with the minutes of the proceedings of the
Board or committee.

SECTION 12.  TELEPHONIC MEETINGS

     Members of the Board, or any committee designated by the Board, may
participate in any meeting of the Board or committee by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in such a
meeting shall constitute presence in person at such meeting.

     Each Director, who is not a full-time salaried officer of the corporation
or any of its wholly owned subsidiaries, when authorized by resolution of the
Board, may receive as a Director a stated salary or an annual retainer, and any
other benefits as the Board may determine, and in addition may be allowed a
fixed fee or reimbursement of his reasonable expenses for attendance at each
regular or special meeting of the Board or any committee thereof.

SECTION 14.  INTERESTED DIRECTORS

Directors or officers, or between the corporation and any other corporation,
partnership, association or other organization in which one or more of its
Directors or officers are Directors or officers of this corporation, or have a
financial interest in such contract or transaction, shall be void or voidable
solely for this reason, or solely because the Director or officer is present at
or participates in the meeting of the Board or committee thereof which
authorizes the contract or transaction, or solely because his or their votes
are counted for such purpose, if:  (1) the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board or the committee, and the Board or committee in good
faith authorizes the contract or transaction by the affirmative votes of a
majority of the disinterested Directors, even though the disinterested
Directors be less than a quorum; or (2) the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or
are known to the stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders;
or (3) the contract or transaction is fair as to the corporation as of the time
it is authorized, approved or ratified by the Board, a committee thereof or the
stockholders.





                                       8
<PAGE>   13
Common or interested Directors may be counted in determining the presence of a

                                INDEMNIFICATION

SECTION 1.  GENERAL

     The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any contemplated, pending or completed action,
suit, arbitration, alternate dispute resolution mechanism, investigation,
administrative hearing or any other proceeding, whether





                                       18
<PAGE>   23
civil, criminal, administrative or investigative ("Proceeding") (other than a
Proceeding by or in the right of the corporation to procure a judgment in its
favor) in whole or in part attributable to (i) the fact that he is or was a
director or officer of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, employee benefit plan, trust or other
enterprise ("Indemnitee"), or (ii) anything done or not done by such Indemnitee
in any such capacity, against expenses (including attorneys' fees) and losses,
claims, liabilities, judgments, fines and amounts paid in settlement incurred
by him or on his behalf in connection with such Proceeding ("Losses") if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal Proceeding, had no reasonable cause to believe his conduct was
unlawful; provided, however, that except as provided in Section 6 of this
Article X, the corporation shall indemnify any such Indemnitee in connection
with a Proceeding initiated by such Indemnitee only if such Proceeding was
authorized by the Board of Directors.

SECTION 2.  ACTIONS BY OR IN THE RIGHT OF THE CORPORATION

         The corporation shall indemnify any person who was or is made a party
or is threatened to be made a party to any pending, completed or threatened
Proceeding brought by or in the right of the corporation to procure a judgment
in its favor in whole or in part attributable to (i) the fact that he is or was
a director or officer of the corporation, or is or was serving at the request
of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise (also an
"Indemnitee") or (ii) anything done or not done by such Indemnitee in any such
capacity, against expenses (including attorneys' fees) actually incurred by him
or on his behalf in connection with such action or suit if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, provided that no such indemnification shall
be made in respect of any claim, issue or matter as to which Delaware law
expressly prohibits such indemnification by reason of an adjudication of
liability of such person to the corporation unless and only to the extent that
the Court of Chancery of the State of Delaware or the court in which such
action or suit was brought shall determine such indemnification to be equitable
under the circumstances.

SECTION 3.  INDEMNIFICATION IN CERTAIN CASES

         Notwithstanding any other provision of this Article X, to the extent
that an Indemnitee has been wholly successful on the merits or otherwise in
defense of any Proceeding referred to in Sections 1 or 2 of this Article X or
in defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) incurred by him or on his behalf
in connection therewith.  If Indemnitee is not wholly successful in such
Proceeding but is successful, on the merits or otherwise, as to one or more but
less than all claims, issues or matters in such Proceeding, the corporation
shall indemnify Indemnitee, to the maximum extent permitted by law, against
expenses (including attorneys' fees) actually incurred by Indemnitee in
connection with each successfully resolved claim, issue or matter.  For
purposes of this Section 3 and without limitation, the termination of any such
claim, issue or matter by dismissal with or without prejudice shall be deemed
to be a successful resolution as to such claim, issue or matter.





                                       19
<PAGE>   24
SECTION 4.  PROCEDURE

         4.1  Any indemnification under Sections 1 and 2 of this Article X
(unless ordered by a court) shall be made by the corporation only as authorized
in the specific case upon a determination that indemnification of the
Indemnitee is proper (except that the right of Indemnitee to receive payments
pursuant to Section 5 of this Article X shall not be subject to this Section 4)
in the circumstances because he has met the applicable standard of conduct set
forth in such Sections 1 and 2, as applicable.  When seeking indemnification,
Indemnitee shall submit a written request for indemnification to the
corporation.  Such requests shall include documentation or information which is
necessary for the corporation to make a determination of Indemnitee's
entitlement to indemnification and what is reasonably available to Indemnitee.
Such determination shall be made promptly, but in no event later than 30 days
after receipt by the corporation of Indemnitee's written request for
indemnification.  The Secretary of the corporation shall, promptly upon receipt
of Indemnitee's request for indemnification, advise the Board of Directors that
Indemnitee has made such request for indemnification.

         4.2     The entitlement of Indemnitee to indemnification shall be
determined in the specific case by a majority vote of the directors who are
Disinterested Directors, even though less than a quorum, except that such
determination shall be made by Independent Legal Counsel, if either there are
no Disinterested Directors or a majority of such Disinterested Directors so
directs.

         4.3     In the event the determination of entitlement is to be made by
Independent Legal Counsel, such Independent Legal Counsel shall be selected by
the Board of Directors and approved by Indemnitee.  Upon failure of the Board
of Directors to so select such Independent Legal Counsel or upon failure of
Indemnitee to so approve, such Independent Legal Counsel shall be selected by
the Chancellor of the State of Delaware or such other person as such Chancellor
shall designate to make such selection.

         4.4     If the Board of Directors or Independent Legal Counsel shall
have determined that Indemnitee is not entitled to indemnification to the full
extent of Indemnitee's request, Indemnitee shall have the right to seek
entitlement to indemnification in accordance with the procedures set forth in
Section 6 of this Article X.

         4.5     If the person or persons empowered pursuant to Section 4.2 of
this Article X to make a determination with respect to entitlement to
indemnification shall have failed to make the requested determination within 90
days after receipt by the corporation of such request, the requisite
determination of entitlement to indemnification shall be deemed to have been
made and Indemnitee shall be absolutely entitled to such indemnification,
absent (A) misrepresentation by Indemnitee of a material fact in the request
for indemnification or (B) a final judicial determination that all or any part
of such indemnification is expressly prohibited by law.

         4.6     The termination of any Proceeding by judgment, order,
settlement or conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, adversely affect the rights of Indemnitee to
indemnification hereunder except as may be specifically provided herein, or
create a presumption that Indemnitee did not act in good faith and in a manner
which Indemnitee





                                       20
<PAGE>   25
reasonably believed to be in or not opposed to the best interests of the
corporation or create a presumption that (with respect to any criminal action
or proceeding) Indemnitee had reasonable cause to believe that Indemnitee's
conduct was unlawful.

         4.7     For purposes of any determination of good faith hereunder,
Indemnitee shall be deemed to have acted in good faith if Indemnitee's action
is based on the records or books of account of the corporation or an Affiliate,
including financial statements, or on information supplied to Indemnitee by the
officers of the corporation or an Affiliate in the course of their duties, or
on the advice of legal counsel for the corporation or an Affiliate or by an
independent certified public accountant or by an appraiser or other expert
selected with reasonable care by the corporation or an Affiliate.  The
provisions of this Section 4.7 of this Article X shall not be deemed to be
exclusive or to limit in any way the other circumstances in which the
Indemnitee may be deemed to have met the applicable standard of conduct set
forth in these By-laws.

         4.8     The knowledge and/or actions, or failure to act, of any
director, officer, agent or employee of the corporation or an Affiliate shall
not be imputed to Indemnitee for purposes of determining the right to
indemnification under these By-laws.

         4.9     Without limiting the generality of the foregoing, in the event
any Indemnitee is made a party or is threatened to be made a party to any
Proceeding:

         (A)     the Indemnitee may retain counsel satisfactory to him with the
    consent of the corporation, which may not be unreasonably withheld or
    delayed;

         (B)     the corporation shall pay all fees and expenses of such
    counsel for the Indemnitee promptly as statements therefor are received;
    and

         (C)     the corporation will use all reasonable efforts to assist in
    the vigorous defense of any such matter, provided that the corporation
    shall not be liable for any settlement effected without its written
    consent, which consent, however, shall not be unreasonably withheld.

Any Indemnitee wishing to claim indemnification under this Article X, upon
notice that such person has been made or is threatened to be made a party to
any such Proceeding, shall notify the corporation (but any failure so to notify
shall not relieve the corporation from any liability which it may have under
this Article X, except to the extent such failure materially prejudices the
corporation) and shall deliver to the corporation any undertaking required by
Section 145(e) of the Delaware General Corporation Law.  The Indemnitees as a
group may retain only one law firm to represent them with respect to each such
Proceeding unless there is, under applicable standards of professional conduct,
a conflict on any significant issue between the positions of any two or more
Indemnitees.

SECTION 5.  ADVANCES FOR EXPENSES AND COSTS

         All expenses (including attorneys' fees) incurred by or on behalf of
Indemnitee (or reasonably expected by Indemnitee to be incurred by Indemnitee
within three months) in





                                       21
<PAGE>   26
connection with any Proceeding shall be paid by the corporation in advance of
the final disposition of such Proceeding within 20 days after the receipt by
the corporation of a statement or statements from Indemnitee requesting from
time to time such advance or advances whether or not a determination to
indemnify has been made under Section 4 of this Article X (and even if the
Disinterested Directors or Independent Legal Counsel has determined, pursuant
to Section 4, that Indemnitee is not entitled to indemnification by reason of
their conclusions that Indemnitee (i) did not act in good faith or in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of
the corporation or (ii) had reasonable cause to believe his conduct was
unlawful, but not after the conclusion of judicial proceedings under Section
6).  Indemnitee's entitlement to such advancement of expenses shall include
those incurred in connection with any Proceeding by Indemnitee seeking an
adjudication or award in arbitration pursuant to these By-laws.  Such statement
or statements shall evidence such expenses incurred (or reasonably expected to
be incurred) by Indemnitee in connection therewith and shall include or be
accompanied by a written undertaking by or on behalf of Indemnitee to repay
such amount if it shall ultimately be determined that Indemnitee is not
entitled to be indemnified therefor pursuant to the terms of this Section 5 of
Article X.  The financial ability of an Indemnitee to repay an advance shall
not be a prerequisite to the making of such an advance.

SECTION 6.  REMEDIES IN CASES OF DETERMINATION NOT TO INDEMNIFY OR TO ADVANCE
EXPENSES

         6.1     In the event that (A) a determination is made that Indemnitee
is not entitled to indemnification hereunder, (B) advances are not made
pursuant to Section 5 of this Article X or (C) payment has not been timely made
following a determination of entitlement to indemnification pursuant to Section
4 of this Article X, Indemnitee shall be entitled to seek a final adjudication
in an appropriate court of the State of Delaware or any other court of
competent jurisdiction of Indemnitee's entitlement to such indemnification or
advance.

         6.2     In the event a determination has been made in accordance with
the procedures set forth in Section 4 of this Article X, in whole or in part,
that Indemnitee is not entitled to indemnification, any judicial proceeding
referred to in Section 6.1 of this Article X shall be de novo and Indemnitee
shall not be prejudiced by reason of any such prior determination that
Indemnitee is not entitled to indemnification.

         6.3     If a determination is made or deemed to have been made
pursuant to the terms of Sections 4 or 6 of this Article X that Indemnitee is
entitled to indemnification, the corporation shall be bound by such
determination in any judicial proceeding in the absence of (A) a
misrepresentation of a material fact by Indemnitee or (B) a final judicial
determination that all or any part of such indemnification is expressly
prohibited by law.

         6.4     To the extent deemed appropriate by the court, interest shall
be paid by the corporation to Indemnitee at a reasonable interest rate for
amounts which the corporation indemnifies or is obliged to indemnify Indemnitee
for the period commencing with the date on which Indemnitee requested
indemnification (or reimbursement or advance of expenses) and ending with the
date on which such payment is made to Indemnitee by the corporation.

<PAGE>   27
SECTION 7.  RIGHTS NON-EXCLUSIVE

         The rights of indemnification and advancement of expenses provided by,
or granted pursuant to, this Article X shall not be deemed exclusive of any
rights to which any person seeking indemnification or advancement of expenses
may be entitled under any law, certificate of incorporation, by-law, agreement,
vote of stockholders or resolution of directors or otherwise, both as to action
in his official capacity and as to action in another capacity while holding
such office.  No amendment, alteration, rescission or replacement of these
By-laws or any provision hereof shall be effective as to Indemnitee with
respect to any action taken or omitted by such Indemnitee in Indemnitee's
position with the corporation or an Affiliate or any other entity which
Indemnitee is or was serving at the request of the corporation prior to such
amendment, alteration, rescission or replacement.

SECTION 8.  INSURANCE

         The corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnify him against
such liability under the provisions of this Article X.

SECTION 9.  SURVIVING OF RIGHTS

         The indemnification and advancement of expenses provided by, or
granted pursuant to this Article X shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
the heirs, executors and administrators of such a person.

SECTION 10.  INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE CORPORATION

         The corporation may, by action of the Board of Directors from time to
time, grant rights to indemnification and advancement of expenses to employees
and agents of the corporation, with the same scope and effect as the provisions
of this Article X with respect to the indemnification of directors and officers
of the corporation.

SECTION 11.  DEFINITIONS

         For purposes of this Article X:

         (a)     "Affiliate" includes any corporation, partnership, joint
    venture, employee benefit plan, trust or other enterprise directly or
    indirectly owned by the corporation.

         (b)     "Corporation" includes all constituent corporations absorbed
    in a consolidation or merger as well as the resulting or surviving
    corporation so that any person who is or was a





                                       23
<PAGE>   28
    director, officer, employee or agent of such a constituent corporation or is
    or was serving at the request of such constituent corporation as a director,
    officer, employee or agent of another corporation, partnership, joint
    venture, trust or other enterprise shall stand in the same position under
    the provisions of this Article X with respect to the resulting or surviving
    corporation as he would if he had served the resulting or surviving
    corporation in the same capacity.

         (c)     "Disinterested Director" shall mean a director of the
    corporation who is not or was not a party to the Proceeding in respect of
    which indemnification is being sought by Indemnitee.

         (d)     "Independent Legal Counsel" shall mean a law firm or lawyer
    that neither is presently nor in the past five years has been retained to
    represent:  (i) the corporation or Indemnitee in any matter material to
    either such party or (ii) any other party to the Proceeding giving rise to
    a claim for indemnification hereunder.  Notwithstanding the foregoing, the
    term "Independent Counsel" shall not include any firm or person who, under
    the applicable standards of professional conduct then prevailing, would
    have a conflict of interest in representing either the corporation or
    Indemnitee in an action to determine Indemnitee's right to indemnification
    under these By- laws.  All fees and expenses of the Independent Counsel
    incurred in connection with acting pursuant to these By-laws shall be borne
    by the corporation.

circumstances.

SECTION 2.  DEPOSITS

<PAGE>   21
 
                                       13
 
substantially similar tenor signed (either physically or by means of a facsimile
or an electronic transmission, provided that such electronic transmission is
transmitted through the facilities of a Depositary) by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered (either physically or by means of a facsimile or an electronic
transmission, provided that such electronic transmission is transmitted through
the facilities of a Depositary) to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 315 of the
Trust Indenture Act) conclusive in favor of the Trustee and the Company, if made
in the manner provided in this Section.
 
  The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.
 
  The ownership, principal amount and serial numbers of Securities held by any
Person, and the date of commencement of such Person's holding the same, shall be
proved by the Security Register.
 
  Any request, demand, authorization, direction, notice, consent, waiver or
other action of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.
 
  Without limiting the foregoing, a Holder entitled hereunder to give or take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
<PAGE>   22
 
                                       14
 
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any different part of such principal amount.
 
  The Company may set any day as the record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities of such series, but the Company shall have no obligation to do so.
With regard to any record date set pursuant to this paragraph, the Holders of
Outstanding Securities of the relevant series on such record date (or their duly
appointed agents), and only such Persons, shall be entitled to give or take the
relevant action, whether or not such Holders remain Holders after such record
date.
 
  SECTION 105. Notices, Etc., to Trustee and Company.
 
  Any request, demand, authorization, direction, notice, consent, waiver or Act
of Holders or other document provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with,

  every purpose hereunder if made, given, furnished or filed in writing to or
  with the Trustee at its Corporate Trust Office, Attention: Corporate Trustee
  Administration Department, or
 
    (2) the Company by the Trustee or by any Holder shall be sufficient for
  every purpose hereunder (unless otherwise herein expressly provided) if in
  writing and mailed, first-class postage prepaid, to the Company addressed to
  it at 1001 Louisiana, Houston, Texas 77002, to the attention of the Secretary,
  or at any other address previously furnished in writing to the Trustee by the
  Company.
 
  SECTION 106. Notice to Holders; Waiver.
 
  Where this Indenture provides for notice to Holders of any event, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid (if international mail, by air
mail), to each Holder affected by such event, at his address as it appears in
the Security Register, not later than the latest date (if any), and not earlier
than the earliest date (if any), prescribed for the giving of such notice. In
any case where notice to Holders is given by mail, neither the failure to mail
such notice, nor any defect in any notice so mailed, to any particular Holder
shall affect the sufficiency of such notice with respect to other Holders. Any
notice
<PAGE>   23
 
                                       15
 
mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually
receives such notice.
 
  Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.
 
  In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.
 
  SECTION 107. Conflict with Trust Indenture Act.
 
  If any provision hereof limits, qualifies or conflicts with a provision of the
Trust Indenture Act that is required under such Act to be a part of and govern
this Indenture, the latter provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or excluded, as the case may be.
 
  SECTION 108. Effect of Headings and Table of Contents.
 
  The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.
 
  SECTION 109. Successors and Assigns.
 
  All covenants and agreements in this Indenture by the Company shall bind its
successors and assigns, whether so expressed or not.
 
  SECTION 110. Separability Clause.
 
  In case any provision in this Indenture or in the Securities shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.
 
  SECTION 111. Benefits of Indenture.
 
  Nothing in this Indenture or in the Securities, express or implied, shall give
to any Person, other than the parties hereto and their successors hereunder and

  THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.
 
  SECTION 113. Legal Holidays.
 
  In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of the Securities of any series which specifically
states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest Payment Date,
Redemption Date or Stated Maturity, as the case may be.
 
  SECTION 114. Language of Notices, Etc.
 
  Any request, demand, authorization, direction, notice, consent, waiver or Act
required or permitted under this Indenture shall be in the English language,
except that any published notice may be in an official language of the country
of publication.
 
  SECTION 115. Incorporators, Stockholders, Officers and Directors of the
Company Exempt from Individual Liability.
 
  No recourse under or upon any obligation, covenant or agreement of or
contained in this Indenture or of or contained in any Security, or for any claim
based thereon or otherwise in respect thereof, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or any successor Person, either directly or through the
Company or any successor Person, whether by virtue of any constitution, statute
or rule of law, or by the enforcement of any assessment or penalty or otherwise;

this series, the Holders of not less than 25% in principal amount of the
Securities of all affected series at the time Outstanding (treated as a single
class) shall have made written request to the Trustee to institute proceedings
in respect of such Event of Default as Trustee and offered the Trustee
reasonable indemnity and the Trustee shall not have received from the Holders of
a majority in principal amount of Securities of this series at the time
Outstanding a direction inconsistent with such request, and shall have failed to
institute any such proceeding, for 60 days after receipt of such notice, request
and offer of indemnity. The foregoing shall not apply to any suit instituted by
the Holder of this Security for the enforcement of any payment of principal
hereof or [any premium or] interest hereon on or after the respective due dates
expressed herein.

tenor, of authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.]

contained in the Indenture or of or contained in any Security, or for any claim
based thereon or otherwise in respect thereof, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor Person, either directly or through
the Company or any successor Person, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment, penalty or
otherwise; it being expressly understood that all such liability is hereby
expressly waived and released by the acceptance hereof and as a condition of,
and as part of the consideration for, the Securities and the execution of the
Indenture.
 
  The Indenture provides that the Company (a) will be discharged from any and
all obligations in respect of the Securities (except for certain obligations
described in the Indenture), or (b) need not comply with certain restrictive
covenants of the Indenture, in each case if the Company deposits, in trust, with
the Trustee money or U.S. Government Obligations (or a combination thereof)
which through the payment of interest thereon and principal thereof in
accordance with their terms will provide money, in an amount sufficient to

                                       27

be segregated from other funds except to the extent required by law.
 
  This Security shall be governed by and construed in accordance with the laws
of the State of New York.

Company's agents designated in an Officer's Certificate, in accordance with a
Company Order.
 
  SECTION 302. Denominations.
 
  The Securities of each series shall be issuable only in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such specified denomination with respect to
the Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.
 
  SECTION 303. Execution, Authentication, Delivery and Dating.
 
  The Securities shall be executed on behalf of the Company by its Chairman of
the Board, its Chief Executive Officer, its Chief Financial Officer, its
President or any Vice President and need not be attested. The signature of any
of these officers on the Securities may be manual or facsimile.
 
  Securities bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.
 
  At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities; provided,
however, that in the case of Securities offered in a Periodic Offering, the
Trustee shall authenticate and deliver such Securities from time to time in
accordance with such other procedures (including, without limitation, the
receipt by the Trustee of oral or electronic instructions from the Company or
its duly authorized agents, thereafter promptly confirmed in writing) acceptable
to the Trustee as may be specified by or pursuant to a Company Order delivered
to the Trustee prior to the time of the first authentication of Securities of
such series. If the form or terms of the
<PAGE>   41
 
                                       33
 
Securities of the series have been established in or pursuant to one or more
Board Resolutions as permitted by Sections 201 and 301, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating,
 
    (1) if the form or forms of such Securities have been established by or
  pursuant to Board Resolution as permitted by Section 201, that such form or
  forms have been established in conformity with the provisions of this
  Indenture;
 
    (2) if the terms of such Securities have been, or in the case of Securities
  of a series offered in a Periodic Offering, will be, established by or
  pursuant to a Board Resolution as permitted by Section 301, that such terms
  have been, or in the case of Securities of a series offered in a Periodic
  Offering, will be, established in conformity with the provisions of this
  Indenture, subject, in the case of Securities of a series offered in a
  Periodic Offering, to any conditions specified in such Opinion of Counsel; and
 
    (3) that such Securities, when authenticated and delivered by the Trustee
  and issued by the Company in the manner and subject to any conditions
  specified in such Opinion of Counsel, will constitute valid and legally
  binding obligations of the Company enforceable in accordance with their terms,
  subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
  moratorium and similar laws of general applicability relating to or affecting
  creditors' rights and to general equity principles.
 
If such form or forms or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.
 
  Notwithstanding the provisions of Section 301 and of the preceding paragraph,
if all Securities of a series are not to be originally issued at one time, it
shall not be necessary to deliver the Officer's Certificate otherwise required
pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise
required pursuant to such preceding paragraph at or prior to the time of
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.
<PAGE>   42
 
                                       34
 
  With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Company of any of such
Securities, the form or forms and terms thereof and the legality, validity,
binding effect and enforceability thereof, upon the Opinion of Counsel and the
other documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.
 
  Each Security shall be dated the date of its authentication.
 
  No Security shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 309 for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.
 
  SECTION 304. Temporary Securities.
 
  Pending the preparation of Definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the Definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.
 
  If temporary Securities of any series are issued, the Company will cause
Definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of Definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for Definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company maintained pursuant to Section 1002 for the
purpose of exchanges of Securities of such series, without charge to the Holder.
Upon
<PAGE>   43
 
                                       35
 
surrender for cancellation of any one or more temporary Securities of any series
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor one or more Definitive Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor.
Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as Definitive Securities
of such series and tenor.
 
  SECTION 305. Registration, Registration of Transfer and Exchange.
 
  The Company shall cause to be kept at an office or agency of the Company in
The City of New York a register (the register maintained in such office or in
any other office or agency of the Company in a Place of Payment being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Company will,
prior to the issuance of any Securities hereunder, appoint the Trustee as the
initial "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided and its corporate trust office which,
at the date hereof, is located at 450 West 33rd Street, New York, New York 10001
as the initial office or agency in The City of New York where the Security
Register will be maintained. The Company may at any time replace such Security
Registrar, change such office or agency or act as its own Security Registrar.
The Company will give prompt written notice to the Trustee of any change of the
Security Registrar or of the location of such office or agency.
 
  Upon surrender for registration of transfer of any Security of any series at
the office or agency of the Company maintained pursuant to Section 1002 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.
 
  At the option of the Holder, Securities of any series (except a Global
Security) may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.
<PAGE>   44
 
                                       36
 
  All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.
 
  Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.
 
  No service charge shall be made for any registration of transfer or exchange
of Securities, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 304, 906 or 1107 not involving any transfer.
 
  The Company shall not be required (1) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (2) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.
 
  Notwithstanding any other provision in this Indenture and except as otherwise
specified as contemplated by Section 301, no Global Security may be transferred
to, or registered or exchanged for Securities registered in the name of, any
Person other than the Depositary for such Global Security or any nominee
thereof, and no such transfer may be registered, except as provided in this
paragraph. Every Security authenticated and delivered upon registration or
transfer of, or in exchange for or in lieu of, a Global Security shall be a
Global Security, except as provided in this paragraph. If (1) (A) the Depositary
for a Global Security notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or ceases to be a clearing
agency registered under the Exchange Act, and (B) a successor Depositary is not
appointed by the Company within 90 days, or (2) the Company determines in its
sole discretion that Securities of a series issued in global form shall no
longer be represented by a Global Security, then such Global Security may be
exchanged by such Depositary for Definitive Securities of the same series, of
any authorized denomination and of a like aggregate principal amount and
<PAGE>   45
 
                                       37
 
tenor, registered in the names of, and the transfer of such Global Security or
portion thereof may be registered to, such Persons as such Depositary shall
direct.
 
  SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.
 
  If any mutilated Security is surrendered to the Trustee, together with, in
proper cases, such security or indemnity as may be required by the Company or
the Trustee to save each of them and any agent of either of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.
 
  If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.
 
  In case any such mutilated, destroyed, lost or stolen Security has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, pay such Security.
 
  Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.
 
  Every new Security of any series issued pursuant to this Section in exchange
for any mutilated Security or in lieu of any destroyed, lost or stolen Security
shall constitute an original additional contractual obligation of the Company,
whether or not the mutilated, destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series duly issued hereunder.
<PAGE>   46
 
                                       38
 
  The provisions of this Section are exclusive and shall preclude (to the extent
lawful) all other rights and remedies with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities.
 
  SECTION 307. Payment of Interest; Interest Rights Preserved.
 
  Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.
 
  Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:
 
    (1) The Company may elect to make payment of any Defaulted Interest to the
  Persons in whose names the Securities of such series (or their respective
  Predecessor Securities) are registered at the close of business on a Special
  Record Date for the payment of such Defaulted Interest, which shall be fixed
  in the following manner. The Company shall notify the Trustee in writing of
  the amount of Defaulted Interest proposed to be paid on each Security of such
  series and the date of the proposed payment, and at the same time the Company
  shall deposit with the Trustee an amount of money equal to the aggregate
  amount proposed to be paid in respect of such Defaulted Interest or shall make
  arrangements satisfactory to the Trustee for such deposit prior to the date of
  the proposed payment, such money when deposited to be held in trust for the
  benefit of the Persons entitled to such Defaulted Interest as in this clause
  provided. Thereupon the Trustee shall fix a Special Record Date for the
  payment of such Defaulted Interest which shall be not more than 15 days and
  not less than 10 days prior to the date of the proposed payment and not less
  than 10 days after the receipt by the Trustee of the notice of the proposed
  payment. The Trustee shall promptly notify the Company of such Special Record
  Date and, in the name and at the expense of the Company, shall cause notice of
  the proposed payment of such Defaulted Interest and the Special Record Date
  therefor to be mailed, first-class postage prepaid, to each Holder of
  Securities of such series at his address as it appears in the Security
  Register, not less than 10 days prior to such Special Record Date. Notice of
  the proposed payment of such Defaulted Interest and the Special Record Date
  therefor having been so
<PAGE>   47
 
                                       39
 
  mailed, such Defaulted Interest shall be paid to the Persons in whose names
  the Securities of such series (or their respective Predecessor Securities) are
  registered at the close of business on such Special Record Date and shall no
  longer be payable pursuant to the following clause (2).
 
    (2) The Company may make payment of any Defaulted Interest on the Securities
  of any series in any other lawful manner not inconsistent with the
  requirements of any securities exchange on which such Securities may be
  listed, and upon such notice as may be required by such exchange, if, after
  notice given by the Company to the Trustee of the proposed payment pursuant to
  this Clause, such manner of payment shall be deemed practicable by the
  Trustee.
 
  Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.
 
  SECTION 308. Persons Deemed Owners.
 
  Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, prior to due presentment of a Security for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of
and any premium and (subject to Sections 305 and 307) any interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.
 
  No holder of any beneficial interest in any Global Security held on its behalf
by a Depositary shall have any rights under this Indenture with respect to such
Global Security, and such Depositary may be treated by the Company, the Trustee,
and any agent of the Company or the Trustee as the owner of such Global Security
for all purposes whatsoever. None of the Company, the Trustee nor any agent of
the Company or the Trustee will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of a Global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

  SECTION 309. Cancellation.
 
  All Securities surrendered for payment, redemption, registration of transfer
or exchange or for credit against any sinking fund payment shall, if surrendered
to any Person other than the Trustee, be delivered to the Trustee and shall be
promptly cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of in accordance with its customary procedures, and
the Trustee shall thereafter deliver to the Company a certificate with respect
to such disposition.
 
  SECTION 310. Computation of Interest.
 
  Except as otherwise specified in or as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.
 
  SECTION 311. CUSIP Numbers.
 
  The Company in issuing the Securities may use "CUSIP" numbers (in addition to
the other identification numbers printed on the Securities), and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such "CUSIP" numbers either as
printed on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such "CUSIP" numbers.

  SECTION 401. Satisfaction and Discharge of Indenture.
 
  This Indenture shall upon Company Request cease to be of further effect with
respect to Securities of any series (except as to any surviving rights of
registration of transfer or exchange of such Securities herein expressly
provided for), and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture
with respect to such Securities, when
 
     (1) either
 
       (A) all such Securities theretofore authenticated and delivered (other
     than (i) such Securities which have been destroyed, lost or stolen and
     which have been replaced or paid as provided in Section 306, and (ii) such
     Securities for whose payment money or U.S. Government Obligations has
     theretofore been deposited in trust or segregated and held in trust by the
     Company and thereafter repaid to the Company or discharged from such trust,
     as provided in Section 1003) have been delivered to the Trustee for
     cancellation; or
 
       (B) all such Securities not theretofore delivered to the Trustee for
     cancellation
 
         (i) have become due and payable, or
 
         (ii) will become due and payable at their Stated Maturity within one
       year, or
 
         (iii) are to be called for redemption within one year under
       arrangements satisfactory to the Trustee for the giving of notice of
       redemption by the Trustee in the name, and at the expense, of the
       Company,
 
  and the Company in the case of (i), (ii) or (iii) above, has deposited or
  caused to be deposited with the Trustee as trust funds in trust for the
  purpose an amount of money in the currency or currency units in which such
  Securities are payable or, if such Securities are payable in United States
  Dollars, U.S. Government Obligations sufficient to pay and discharge the
  entire indebtedness on such Securities not theretofore delivered to the
  Trustee for cancellation, for principal and any premium and interest to the
  date of such deposit (in the case of Securities which have become due and
  payable) or to the Stated Maturity or Redemption Date, as the case may be;
 
    (2) the Company has paid or caused to be paid all other sums payable
  hereunder by the Company with respect to such Securities; and

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

to Securities of any series, (x) the obligations of the Company to the Trustee
under Section 607, the obligations of the Trustee to any Authenticating Agent
under Section 614 and the right of the Trustee to resign under Section 610 shall

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 any
premium and interest for whose payment such money or U.S. Government Obligations
has been deposited with the Trustee.

series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

  solely for the benefit of series of Securities other than that series), and
  continuance of such default or breach for a period of 60 days after there has
  been given, by registered or certified mail, to the Company by the Trustee or
  to the Company and the Trustee by the Holders of at least 25% in principal
  amount of the Outstanding Securities of all series outstanding (or, if any
  such term, covenant or warranty is not applicable to all series of Securities,
  by the Holders of at least 25% in principal amount of the Outstanding
  Securities of all series to which it is applicable) (in each case treated as a
  single class) a written notice specifying such default or breach and requiring

    (6) any other Event of Default provided as contemplated by Section 301 with
  respect to Securities of that series.
 
     SECTION 502. Acceleration of Maturity; Rescission and Annulment.
 
  If an Event of Default of the type described in clauses (1), (2), (3) or (6)
of Section 501 occurs and is continuing, then, and in each and every such case,
except for any series of Securities the principal of which shall have already
become due and payable, either the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Securities of all affected series then
Outstanding hereunder (voting as a single class) by notice in writing to the
Company (and to the Trustee if given by Holders), may declare the entire
principal (or, if the Securities of any such affected series are Original Issue
Discount Securities, such portion of the principal amount as may be specified
<PAGE>   52
 
                                       44
 
in the terms of such series) of all Securities of all such affected series, and
the interest accrued thereon, if any, to be due and payable immediately, and
upon any such declaration the same shall become immediately due and payable.
 
  If an Event of Default of the type described in clause (4) or (5) of Section

any series of Securities the principal of which shall have already become due
and payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of all the Securities then Outstanding hereunder (voting as a
single class), by notice in writing to the Company (and to the Trustee if given
by Holders), may declare the entire principal (or, if Securities of any series
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of such series) of all the Securities then
Outstanding, and interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due
and payable.
 
  At any time after such a declaration of acceleration with respect to
Securities of all affected 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 all such affected series (voting as a single class) by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if
 
    (1) the Company has paid or deposited with the Trustee a sum sufficient to
  pay
 
       (A) all overdue interest on all such affected Securities,
 
       (B) the principal of (and premium, if any, on) any such affected
     Securities which have become due otherwise than by such declaration of
     acceleration and any interest thereon at the rate or rates prescribed
     therefor in such Securities,
 
       (C) to the extent that payment of such interest is lawful, interest upon
     overdue interest at the rate or rates prescribed therefor in such
     Securities, and
 
       (D) all sums paid or advanced by the Trustee hereunder and the reasonable
     compensation, expenses, disbursements and advances of the Trustee, its
     agents and counsel;
<PAGE>   53
 
                                       45
 
     and
 
    (2) all Events of Default with respect to such affected Securities, 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 513.
 
No such rescission shall affect any subsequent Default or impair any right
consequent thereon.
 
  SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.
 
     The Company covenants that if
 
    (1) default is made in the payment of any interest on any Security when such
  interest becomes due and payable and such default continues for a period of 30
  days, or
 
    (2) default is made in the payment of the principal of (or premium, if any,
  on) any Security at the Maturity thereof,
 
the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.
 
  If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.
 
  If an Event of Default with respect to Securities of any series occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Securities of such series by such
<PAGE>   54
 
                                       46
 
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.
 
  SECTION 504. Trustee May File Proofs of Claim.
 
  In case of any judicial proceeding relative to the Company or any other
obligor upon the Securities, their property or their creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.
 
  No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.
 
  SECTION 505. Trustee May Enforce Claims Without Possession of Securities.
 
  All rights of action and claims under this Indenture or the Securities may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the
<PAGE>   55
 
                                       47
 
Holders of the Securities in respect of which such judgment has been recovered.
 
  SECTION 506. Application of Money Collected.
 
  Any money collected by the Trustee pursuant to this Article shall be applied
in the following order, at the date or dates fixed by the Trustee and, in case
of the distribution of such money on account of principal or any premium or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:
 
    FIRST: To the payment of all amounts due the Trustee under Section 607;
 
    SECOND: To the payment of the amounts then due and unpaid for principal of
  and any premium and interest on the Securities in respect of which or for the
  benefit of which such money has been collected, ratably, without preference or
  priority of any kind, according to the amounts due and payable on such
  Securities for principal and any premium and interest, respectively; and
 
    THIRD: The balance, if any, to the Company.
 
  SECTION 507. Limitation on Suits.
 
  No Holder of any Security of any series shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
 
    (1) such Holder has previously given written notice to the Trustee of a
  continuing Event of Default with respect to the Securities of that series;
 
    (2) the Holders of not less than 25% in principal amount of the Outstanding
  Securities of all affected series (treated as a single class) shall have made
  written request to the Trustee to institute proceedings in respect of such
  Event of Default in its own name as Trustee hereunder;
 
    (3) such Holder or Holders have offered to the Trustee reasonable indemnity
  against the costs, expenses and liabilities to be incurred in compliance with
  such request;
 
    (4) the Trustee for 60 days after its receipt of such notice, request and
  offer of indemnity has failed to institute any such proceeding; and
 
    (5) no direction inconsistent with such written request has been given to
  the Trustee during such 60-day period by the Holders of a majority in
  principal amount of the Outstanding Securities of that series;
<PAGE>   56
 
                                       48
 
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.
 
  SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest.
 
  Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Sections 305 and
307) interest on such Security on the respective 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 509. Restoration of Rights and Remedies.
 
  If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder, and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.
 
  SECTION 510. Rights and Remedies Cumulative.
 
  Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.
<PAGE>   57
 
                                       49
 
  SECTION 511. Delay or Omission Not Waiver.
 
  No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.
 
  SECTION 512. Control by Holders.
 
  The Holders of a majority in aggregate principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series; provided, however, that
 
    (1) such direction shall not be in conflict with any rule of law or with
  this Indenture;
 
    (2) the Trustee may take any other action deemed proper by the Trustee which
  is not inconsistent with such direction; and
 
    (3) subject to the provisions of Section 601, the Trustee shall have the
  right to decline to follow any such direction if the Trustee in good faith
  shall determine that the proceeding so directed would involve the Trustee in
  personal liability.
 
  SECTION 513. Waiver of Past Defaults.
 
  The Holders of a majority in aggregate principal amount of the Outstanding
Securities of all series with respect to which an Event of Default shall have
occurred and be continuing (voting as a single class) may on behalf of the
Holders of all such Securities waive any past default hereunder with respect to
such Securities and its consequences, except
 
    (1) a continuing default in the payment of the principal of or any premium
  or interest on any such Security, or
 
    (2) a default in respect of a covenant or provision hereof which under
  Article Nine cannot be modified or amended without the consent of the Holder
  of each Outstanding Security of such series affected.
 
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
<PAGE>   58
 
                                       50
 
purpose of this Indenture, but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.
 
  SECTION 514. Undertaking for Costs.
 
  In any suit for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken, suffered or omitted by
it as Trustee, a court may require any party litigant in such suit to file an
undertaking to pay the costs of such suit, and may assess costs against any such
party litigant, in the manner and to the extent provided in the Trust Indenture
Act; provided, however, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.
 
  SECTION 515. Waiver of Usury, Stay or Extension Laws.
 
  The Company covenants (to the extent that it may lawfully do so) that it will
not at any time insist upon, or plead, or in any manner whatsoever claim or take
the benefit or advantage of, any usury, stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

  SECTION 601. Certain Duties and Responsibilities.
 
  The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section.

                                       51
 
  SECTION 602. Notice of Defaults.
 
  If a Default occurs and is continuing with respect to the Securities of any
series, the Trustee shall, within 90 days after it occurs, transmit, in the
manner and to the extent provided in Section 313(c) of the Trust Indenture Act,
notice of all uncured or unwaived Defaults known to it; provided, however, that,
except in the case of a Default in payment on the Securities of any series, the
Trustee may withhold the notice if and so long as the board of directors, the
executive committee or a trust committee of its directors and/or its duly
authorized officers in good faith determines that withholding such notice is in
the interests of Holders of Securities of such series; provided further,
however, that, in the case of any default or breach of the character specified
in Section 501(3) with respect to the Securities of such series, no such notice
to Holders shall be given until at least 60 days after the occurrence thereof.
 
  SECTION 603. Certain Rights of Trustee.
 
  Subject to the provisions of Section 601:
 
    (1) the Trustee may rely on and shall be protected in acting or refraining
  from acting upon any resolution, certificate, statement, instrument, opinion,
  report, notice, request, direction, consent, order, bond, debenture, note,
  other evidence of indebtedness or other paper or document reasonably believed
  by it to be genuine and to have been signed or presented by the proper party
  or parties;
 
    (2) any request, direction, order or demand of the Company mentioned herein
  shall be sufficiently evidenced by a Company Request or Company Order (other

  pursuant to Section 303, which shall be sufficiently evidenced as provided
  therein) and any resolution of the Board of Directors shall be sufficiently
  evidenced by a Board Resolution;
 
    (3) whenever in the administration of this Indenture the Trustee shall deem
  it desirable that a matter be proved or established prior to taking, suffering
  or omitting any action hereunder, the Trustee (unless other evidence be herein
  specifically prescribed) may, in the absence of bad faith on its part, rely
  upon an Officer's Certificate;
 
    (4) the Trustee may consult with counsel and the written advice of such
  counsel or any Opinion of Counsel shall be full and complete authorization and
  protection in respect of any action taken, suffered or omitted by it hereunder
  in good faith and in reliance thereon;
 
    (5) the Trustee shall be under no obligation to exercise any of the rights
  or powers vested in it by this Indenture at the request or direction of any of
<PAGE>   60
 
                                       52
 
  the Holders pursuant to this Indenture, unless such Holders shall have offered
  to the Trustee reasonable security or indemnity against the costs, expenses
  and liabilities which might be incurred by it in compliance with such request
  or direction;
 
    (6) the Trustee shall not be bound to make any investigation into the facts
  or matters stated in any resolution, certificate, statement, instrument,
  opinion, report, notice, request, direction, consent, order, bond, debenture,
  note, other evidence of indebtedness or other paper or document but the
  Trustee, in its discretion, may make such further inquiry or investigation
  into such facts or matters as it may see fit;
 
    (7) the Trustee may execute any of the trusts or powers hereunder or perform
  any duties hereunder either directly or by or through agents or attorneys and
  the Trustee shall not be responsible for any misconduct or negligence on the
  part of any agent or attorney appointed with due care by it hereunder; and
 
    (8) the Trustee may request that the Company deliver an Officer's
  Certificate setting forth the names of individuals and/or titles of officers
  authorized at such time to take specified actions pursuant to this Indenture,
  which Officer's Certificate may be signed by any person authorized to sign an
  Officer's Certificate, including any person specified as so authorized in any
  such certificate previously delivered and not superseded.
 
  SECTION 604. Not Responsible for Recitals or Issuance of Securities.
 
  The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their
correctness Neither the Trustee nor any Authenticating Agent makes any
representations as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee or any Authenticating Agent shall not be accountable for
the use or application by the Company of Securities or the proceeds thereof.
 
  SECTION 605. May Hold Securities.
 
  The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would

Registrar or such other agent.

  SECTION 606. Money Held in Trust.
 
  Money held by the Trustee in trust hereunder need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.
 
  SECTION 607. Compensation and Reimbursement.
 
  The Company agrees
 
    (1) to pay to the Trustee from time to time reasonable compensation for all
  services rendered by it hereunder (which compensation shall not be limited by
  any provision of law in regard to the compensation of a trustee of an express
  trust);
 
    (2) except as otherwise expressly provided herein, to reimburse the Trustee
  upon its request for all reasonable expenses, disbursements and advances
  incurred or made by the Trustee in accordance with any provision of this
  Indenture (including the reasonable compensation and the expenses and
  disbursements of its agents and counsel), except any such expense,
  disbursement or advance as may be attributable to its negligence or bad faith;
  and
 
    (3) to indemnify the Trustee for, and to hold it harmless against, any loss,
  liability or expense incurred without negligence or bad faith on its part,
  arising out of or in connection with the acceptance or administration of the
  trust or trusts hereunder, including the costs and expenses of defending
  itself against any claim or liability in connection with the exercise or
  performance of any of its powers or duties hereunder, except those
  attributable to its negligence or bad faith.
 
  The obligations of the Company under this Section to compensate the Trustee
and to pay or reimburse the Trustee for expenses, disbursements and advances
shall constitute additional indebtedness hereunder. Such additional indebtedness
shall be secured by a lien prior to that of the Securities upon all property and
funds held or collected by the Trustee as such, except funds held in trust for
the benefit of the Holders of particular Securities.
 
  Without limiting any rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with an Event
of Default specified in Section 501(4) or Section 501(5), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for such services are intended to constitute expenses of
administration under any applicable Bankruptcy Law.

                                       54
 
  The provisions of this Section shall survive the satisfaction and discharge of
this Indenture and the defeasance of the Securities.
 
  SECTION 608. Disqualification; Conflicting Interests.
 
  If the Trustee has or shall acquire a conflicting interest within the meaning
of the Trust Indenture Act, the Trustee shall either eliminate such interest or
resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture.
 
  SECTION 609. Corporate Trustee Required; Eligibility.
 
  There shall at all times be one or more Trustees hereunder with respect to the
Securities of each series, at least one of which shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus required by the Trust Indenture Act. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of a supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.
 
  SECTION 610. Resignation and Removal; Appointment of Successor.
 
  No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 611.
 
  The Trustee may resign at any time with respect to the Securities of one or
more series by giving written notice thereof to the Company. If the instrument
of acceptance by a successor Trustee required by Section 611 shall not have been
delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.
 
  The Trustee may be removed at any time with respect to the Securities of any
series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of all series for which such Trustee is acting as
Trustee, delivered to the Trustee and to the Company.
<PAGE>   63
 
                                       55
 
  If at any time:
 
    (1) the Trustee shall fail to comply with Section 608 after written request
  therefor by the Company or by any Holder who has been a bona fide Holder of a
  Security for at least six months, or
 
    (2) the Trustee shall cease to be eligible under Section 609 and shall fail
  to resign after written request therefor by the Company or by any such Holder,
  or
 
    (3) the Trustee shall become incapable of acting or shall be adjudged a
  bankrupt or insolvent or a receiver of the Trustee or of its property shall be
  appointed or any public officer shall take charge or control of the Trustee or
  of its property or affairs for the purpose of rehabilitation, conservation or
  liquidation,
 
then, in any such case, (A) the Company may remove the Trustee with respect to
all Securities, or (B) subject to Section 514, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee with respect to all Securities and the appointment of
a successor Trustee or Trustees.
 
  If the Trustee shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of Trustee for any cause, with respect to the
Securities of one or more series, the Company shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of that or those series (it
being understood that any such successor Trustee may be appointed with respect
to the Securities of one or more or all of such series and that at any time
there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 611. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 611, become the successor Trustee with
respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by
<PAGE>   64
 
                                       56
 
Section 611, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.
 
  The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders of
Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.
 
  SECTION 611. Acceptance of Appointment by Successor.
 
  (a) In case of the appointment hereunder of a successor Trustee with respect
to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.
 
  (b) In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or

change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees as co-trustees of the same trust and
that each such Trustee shall be trustee of a trust or trusts hereunder separate
and apart from any trust or trusts hereunder administered by any other such
Trustee; and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.
 
  (c) Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.
 
  (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.
 
  SECTION 612. Merger, Conversion, Consolidation or Succession to Business
 
  Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

                                       58
 
  SECTION 613. Preferential Collection of Claims Against Company.
 
  If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).
 
  SECTION 614. Appointment of Authenticating Agent.
 
  The Trustee (upon notice to the Company) may appoint an Authenticating Agent
or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue (in accordance with procedures acceptable to
the Trustee) and upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.
 
  Any corporation into which an Authenticating Agent may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Authenticating Agent shall be
a party, or any corporation succeeding to all or substantially all
<PAGE>   67
 
                                       59
 
of the corporate agency or corporate trust business of such Authenticating
Agent, shall continue to be an Authenticating Agent, provided such corporation
shall be otherwise eligible under this Section, without the execution or filing
of any paper or any further act on the part of the Trustee or such
Authenticating Agent.
 
  An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.
 
  Except with respect to an Authenticating Agent appointed at the request of the
Company, the Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed by the Company for such payments,
subject to the provisions of Section 607.
 
  If an appointment with respect to one or more series is made pursuant to this
Section, the Securities of such series may have endorsed thereon, in addition to
the Trustee's certificate of authentication, an alternative certificate of
authentication in the following form:
<PAGE>   68
 
                                       60
 
  This is one of the Securities of the series designated therein referred to in
the within-mentioned Indenture.

  days after the receipt by the Company of any such request, a list of similar

  series) or to surrender any right or power herein conferred upon the Company;
  or
 
    (4) to add to, change or eliminate any of the provisions of this Indenture
  in respect of one or more series of Securities; provided, however, that any

    (5) to establish the form or terms of Securities of any series as permitted
  by Sections 201 and 301; or

                                       64
 
    (6) to cure any ambiguity, to correct or supplement any provision herein
  which may be inconsistent with any other provision herein, to comply with any
  applicable mandatory provisions of law or to make any other provisions with
  respect to matters or questions arising under this Indenture, provided that

    (7) to evidence and provide for the acceptance of appointment hereunder by a
  successor Trustee with respect to the Securities of one or more series and to

  under the Trust Indenture Act or under any similar federal statute
  subsequently enacted, and to add to this Indenture such other provisions as

  SECTION 902. Supplemental Indentures with Consent of Holders.

                                       65

  however, that this clause shall not be deemed to require the consent of any
  Holder with respect to changes in the references to "the Trustee" and
  concomitant changes in this Section, or the deletion of this proviso, in
  accordance with the requirements of Sections 611 and 901(7).

provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.
 
  It shall not be necessary for any Act of Holders under this Section to approve
the particular form of any proposed supplemental indenture, but it shall be
sufficient if such Act shall approve the substance thereof.
 
  SECTION 903. Execution of Supplemental Indentures.
 
  In executing, or accepting the additional trusts created by, any supplemental

executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.
 
                                  ARTICLE TEN
 
                                   COVENANTS
 
  SECTION 1001. Payment of Principal, Premium and Interest.
 
  The Company covenants and agrees for the benefit of each series of Securities
that it will duly and punctually pay the principal of and any premium and
interest on the Securities of that series in accordance with the terms of the
Securities and this Indenture.
 
  SECTION 1002. Maintenance of Office or Agency.
 
  The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.
<PAGE>   75
 
                                       67
 
  The Company may also from time to time designate one or more other offices or
agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.
 
  Except as otherwise specified with respect to a series of Securities as
contemplated by Section 301, the Company hereby initially designates as the
Place of Payment for each series of Securities The City and State of New York,
and initially appoints the Trustee at its Corporate Trust Office as the
Company's office or agency for each such purpose in such city.
 
  SECTION 1003. Money for Securities Payments to Be Held in Trust.
 
  If the Company shall at any time act as its own Paying Agent with respect to
any series of Securities, it will, on or before each due date of the principal
of or any premium or interest on any of the Securities of that series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.
 
  Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, on or prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.
 
  The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will (1) hold all sums held by it for the
payment of the principal of (and premium, if any) or interest, if any, on
Securities of that series in trust for the benefit of the Persons entitled
thereto until such sums shall be paid to such Persons or otherwise disposed of
as herein provided; (2) give the Trustee notice of any default by the Company
(or any
<PAGE>   76
 
                                       68
 
other obligor upon the Securities of that series) in the making of any payment
of principal (and premium, if any) or interest, if any, on the Securities of
that series; and (3) during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums held in
trust by such Paying Agent for payment in respect of the Securities of that
series.
 
  The Company may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose, pay, or by Company Order
direct any Paying Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.
 
  Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of or any premium or interest
on any Security of any series and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in an Authorized Newspaper in each Place of Payment with
respect to such series, notice that such money remains unclaimed and that, after
a date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company.
 
  SECTION 1004. Statement by Officers as to Default.
 
  The Company will deliver to the Trustee, within 150 days after the end of each
fiscal year of the Company ending after the date hereof, an Officer's
Certificate, stating whether or not to the best knowledge of the signer thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the
<PAGE>   77
 
                                       69
 
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.
 
  SECTION 1005. Existence.
 
  Subject to Article Eight, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence, rights
(charter and statutory) and franchises; provided, however, that the Company
shall not be required to preserve any such right or franchise if it shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company.
 
  SECTION 1006. Limitations on Liens.
 
  The Company will not, nor will it permit any Restricted Subsidiary to, create,
assume, incur or suffer to exist any Lien upon any Principal Property, whether
owned or leased on the date of this Indenture or thereafter acquired, to secure
any Debt of the Company or any other Person (other than the Securities issued
hereunder), without in any such case making effective provision whereby all of
the Securities Outstanding hereunder shall be secured equally and ratably with,
or prior to, such Debt so long as such Debt shall be so secured. This
restriction shall not apply to:
 
    (i) any Lien upon any property or assets of the Company or any Restricted
  Subsidiary in existence on the date of this Indenture or created pursuant to
  an "after-acquired property" clause or similar term in existence on the date
  of this Indenture or any mortgage, pledge agreement, security agreement or
  other similar instrument in existence on the date of this Indenture;
 
    (ii) any Lien upon any property or assets created at the time of acquisition
  of such property or assets by the Company or any Restricted Subsidiary or
  within one year after such time to secure all or a portion of the purchase
  price for such property or assets or Debt incurred to finance such purchase
  price, whether such Debt was incurred prior to, at the time of or within one
  year of such acquisition;
 
    (iii) any Lien upon any property or assets existing thereon at the time of
  the acquisition thereof by the Company or any Restricted Subsidiary (whether
  or not the obligations secured thereby are assumed by the Company or any
  Restricted Subsidiary);
 
    (iv) any Lien upon any property or assets of a Person existing thereon at
  the time such Person becomes a Restricted Subsidiary by acquisition, merger or
  otherwise;
<PAGE>   78
 
                                       70
 
    (v) the assumption by the Company or any Restricted Subsidiary of
  obligations secured by any Lien existing at the time of the acquisition by the
  Company or any Restricted Subsidiary of the property or assets subject to such
  Lien or at the time of the acquisition of the Person which owns such property
  or assets;
 
    (vi) any Lien on property to secure all or part of the cost of construction
  or improvements thereon or to secure Debt incurred prior to, at the time of,
  or within one year after completion of such construction or making of such
  improvements, to provide funds for any such purpose;
 
    (vii) any Lien on any oil, gas, mineral and processing and other plant
  properties to secure the payment of costs, expenses or liabilities incurred
  under any lease or grant or operating or other similar agreement in connection
  with or incident to the exploration, development, maintenance or operation of
  such properties;
 
    (viii) any Lien arising from or in connection with a conveyance by the
  Company or any Restricted Subsidiary of any production payment with respect to
  oil, gas, natural gas, carbon dioxide, sulphur, helium, coal, metals,
  minerals, steam, timber or other natural resources;
 
    (ix) any Lien in favor of the Company or any Restricted Subsidiary;
 
    (x) any Lien created or assumed by the Company or any Restricted Subsidiary
  in connection with the issuance of Debt the interest on which is excludable
  from gross income of the holder of such Debt pursuant to the Internal Revenue
  Code of 1986, as amended, or any successor statute, for the purpose of
  financing, in whole or in part, the acquisition or construction of property or
  assets to be used by the Company or any Subsidiary;
 
    (xi) any Lien upon property or assets of any foreign Restricted Subsidiary
  to secure Debt of that foreign Restricted Subsidiary;
 
    (xii) Permitted Liens;
 
    (xiii) any Lien created by any Alternate Program or any document executed by
  any Subsidiary or Restricted Affiliate in connection therewith, provided that
  such Lien is limited to the trade or other receivables in respect of which
  such Alternate Program is created or exists, and the proceeds thereof;
 
    (xiv) any Lien on Margin Stock;
 
    (xv) any Lien upon any additions, improvements, replacements, repairs,
  fixtures, appurtenances or component parts thereof attaching to or required to
  be attached to property or assets pursuant to the terms of any mortgage,
  pledge agreement, security agreement or other similar instrument, creating a
  Lien upon such property or assets permitted by clauses (i) through (xiv),
  inclusive, of this Section; or
<PAGE>   79
 
                                       71
 
    (xvi) any extension, renewal, refinancing, refunding or replacement (or
  successive extensions, renewals, refinancing, refundings or replacements) of
  any Lien, in whole or in part, that is referred to in clauses (i) through
  (xv), inclusive, of this Section, or of any Debt secured thereby; provided,
  however, that the principal amount of Debt secured thereby shall not exceed
  the greater of the principal amount of Debt so secured at the time of such
  extension, renewal, refinancing, refunding or replacement and the original
  principal amount of Debt so secured (plus in each case the aggregate amount of
  premiums, other payments, costs and expenses required to be paid or incurred
  in connection with such extension, renewal, refinancing, refunding or
  replacement); provided, further, however, that such extension, renewal,
  refinancing, refunding or replacement shall be limited to all or a part of the
  property (including improvements, alterations and repairs on such property)
  subject to the encumbrance so extended, renewed, refinanced, refunded or
  replaced (plus improvements, alterations and repairs on such property).
 
  Notwithstanding the foregoing provisions of this Section, the Company may, and
may permit any Restricted Subsidiary to, create, assume, incur or suffer to
exist any Lien upon any Principal Property to secure any Debt of the Company or
any other Person (other than the Securities) that is not excepted by clauses (i)
through (xvi), inclusive, of this Section without securing the Securities issued
hereunder, provided that the aggregate principal amount of all Debt then
outstanding secured by such Lien and all similar Liens, together with all net
sale proceeds from Sale-Leaseback Transactions (excluding Sale-Leaseback
Transactions permitted by clauses (i) through (iv), inclusive, of Section 1007),
does not exceed 15% of Consolidated Net Tangible Assets.
 
  SECTION 1007. Restriction of Sale-Leaseback Transaction.
 
  The Company will not, nor will it permit any Restricted Subsidiary to, engage
in a Sale-Leaseback Transaction unless:
 
    (i) such Sale-Leaseback Transaction occurs within one year from the date of
  acquisition of the Principal Property subject thereto or the date of the
  completion of construction or commencement of full operations on such
  Principal Property, whichever is later;
 
    (ii) the Sale-Leaseback Transaction involves a lease for a period, including
  renewals, of not more than three years;
 
    (iii) the Company or such Restricted Subsidiary would be entitled to incur
  Debt secured by a Lien on the Principal Property subject thereto in a
  principal amount equal to or exceeding the net sale proceeds from such Sale-
  Leaseback Transaction without securing the Securities; or
<PAGE>   80
 
                                       72
 
    (iv) the Company or such Restricted Subsidiary, within a one-year period
  after such Sale-Leaseback Transaction, applies or causes to be applied an
  amount not less than the net sale proceeds from such Sale-Leaseback
  Transaction to (A) the repayment, redemption or retirement of Funded Debt of
  the Company or any Subsidiary, or (B) investment in another Principal
  Property.
 
  Notwithstanding the foregoing provisions of this Section, the Company may, and
may permit any Restricted Subsidiary to, effect any Sale-Leaseback Transaction
that is not excepted by clauses (i) through (iv), inclusive, of this Section,
provided that the net sale proceeds from such Sale-Leaseback Transaction,
together with the aggregate principal amount of then outstanding Debt (other
than the Securities) secured by Liens upon Principal Properties not excepted by
clauses (i) through (xvi), inclusive, of Section 1006, do not exceed 15% of the
Consolidated Net Tangible Assets.
 
  SECTION 1008. Waiver of Certain Covenants.
 
  The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 1005, 1006 or 1007 with respect to
the Securities of any series if before the time for such compliance the Holders
of at least a majority in aggregate principal amount of the Outstanding
Securities of all affected series (voting as one class) shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.
 
  A waiver which changes or eliminates any term, provision or condition of this
Indenture which has expressly been included solely for the benefit of one or
more particular series of Securities, or which modifies the rights of the
Holders of Securities of such series with respect to such term, provision or
condition, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series.

                            REDEMPTION OF SECURITIES
 
  SECTION 1101. Applicability of Article.
 
  Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.
 
  SECTION 1102. Election to Redeem; Notice to Trustee.
 
  In case of any redemption at the election of the Company of less than all the
Securities of any series, the Company shall, at least 45 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such series to be redeemed and, if applicable,
of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities (1) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (2)
pursuant to an election of the Company which is subject to a condition specified
in the terms of such Securities, the Company shall furnish the Trustee with an
Officer's Certificate evidencing compliance with such restriction or condition.
 
  SECTION 1103. Selection by Trustee of Securities to Be Redeemed.
 
  If less than all the Securities of any series are to be redeemed (unless all
the Securities of such series and of a specified tenor are to be redeemed), the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.
 
  The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.
<PAGE>   82
 
                                       74
 
  For all purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities shall relate, in the case of
any Securities redeemed or to be redeemed only in part, to the portion of the
principal amount of such Securities which has been or is to be redeemed.
 
  SECTION 1104. Notice of Redemption.
 
  Notice of redemption shall be given by first-class mail (if international
mail, by air mail), postage prepaid, mailed not less than 30 nor more than 60
days prior to the Redemption Date, to each Holder of Securities to be redeemed,
at his address appearing in the Security Register.
 
  All notices of redemption shall state:
 
    (1) the Redemption Date,
 
    (2) the Redemption Price,
 
    (3) if less than all the Outstanding Securities of any series and of a
  specified tenor are to be redeemed, the identification (and, in the case of
  partial redemption of any Securities, the principal amounts) of the particular
  Securities to be redeemed,
 
    (4) that on the Redemption Date the Redemption Price will become due and
  payable upon each such Security to be redeemed and, if applicable, that
  interest thereon will cease to accrue on and after said date,
 
    (5) the place or places where such Securities are to be surrendered for
  payment of the Redemption Price, and
 
    (6) that the redemption is for a sinking fund, if such is the case.
 
  Notice of redemption of Securities to be redeemed shall be given by the
Company or, at the Company's request, by the Trustee in the name and at the
expense of the Company.
 
  SECTION 1105. Deposit of Redemption Price.
 
  On or prior to any Redemption Date, the Company shall deposit with the Trustee
or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.
<PAGE>   83
 
                                       75
 
  SECTION 1106. Securities Payable on Redemption Date.
 
  Notice of redemption having been given as aforesaid, the Securities so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest. Upon surrender of any such Security for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.
 
  If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.
 
  SECTION 1107. Securities Redeemed in Part.
 
  Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 SINKING FUNDS
 
  SECTION 1201. Applicability of Article.
 
  The provisions of this Article shall be applicable to any sinking fund for the
retirement of Securities of a series except as otherwise specified in or as
contemplated by Section 301 for Securities of such series.
 
  The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.
 
  SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.
 
  The Company (1) may deliver Outstanding Securities of a series (other than any
previously called for redemption), and (2) may apply as a credit Securities of a
series which have been redeemed either at the election of the Company pursuant
to the terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.
 
  SECTION 1203. Redemption of Securities for Sinking Fund.
 
  Not less than 45 days prior to each sinking fund payment date for any series
of Securities (unless a shorter period shall be satisfactory to the Trustee),
the Company will deliver to the Trustee an Officer's Certificate specifying the
amount of the next ensuing sinking fund payment for that series pursuant to the
terms of that series, the portion thereof, if any, which is to be satisfied by
<PAGE>   85
 
                                       77
 
payment of cash and the portion thereof, if any, which is to be satisfied by
delivering and crediting Securities of that series pursuant to Section 1202 and
stating the basis for such credit and that such Securities have not been
previously so credited, and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.
 
                                ARTICLE THIRTEEN
 
                                   DEFEASANCE
 
  SECTION 1301. Applicability of Article.
 
  The provisions of this Article shall be applicable to each series of
Securities except as otherwise specified as contemplated by Section 301 for
Securities of such series.
 
  SECTION 1302. Legal Defeasance.
 
  In addition to discharge of the Indenture pursuant to Section 401, the Company
shall be deemed to have paid and discharged the entire indebtedness on all the
Securities of such a series on the 91st day after the date of the deposit
referred to in clause (1) below, and the provisions of this Indenture with
respect to the Securities of such series shall no longer be in effect (except as
to (i) rights of registration of transfer and exchange of Securities of such
series and the Company's right of optional redemption, if any, (ii) substitution
of mutilated, destroyed, lost or stolen Securities, (iii) rights of Holders of
Securities to receive payments of principal thereof and interest thereon, upon
the Stated Maturities therefor or on the Redemption Dates therefor (but not upon
acceleration), and remaining rights of the Holders to receive mandatory sinking
fund payments, if any, (iv) the rights, obligations, duties and immunities of
the Trustee hereunder, (v) the rights of the Holders of Securities of such
series as beneficiaries hereof with respect to the property so deposited with
the Trustee payable to all or any of them, and (vi) the obligations of the
Company under Section 1002), and the Trustee, at the expense of the Company,
shall, upon a Company Request, execute proper instruments ac-
<PAGE>   86
 
                                       78
 
knowledging the same, if the conditions set forth below are satisfied
(hereinafter, "defeasance"):
 
    (1) The Company has irrevocably deposited or caused to be deposited with the
  Trustee as trust funds in trust, for the purposes of making the following
  payments, specifically pledged as security for, and dedicated solely to, the
  benefit of the Holders of the Securities of such series (i) cash in an amount,
  or (ii) in the case of any series of Securities the payments on which may only
  be made in legal coin or currency of the United States, U.S. Government
  Obligations, maturing as to principal and interest at such times and in such
  amounts as will insure the availability of cash, or (iii) a combination
  thereof, 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 (A) the principal and interest and premium,
  if any, on all Securities of such series on each date that such principal,
  interest or premium, if any, is due and payable or on any Redemption Date
  established pursuant to clause (3) below, and (B) any mandatory sinking fund
  payments on the dates on which such payments are due and payable in accordance
  with the terms of the Indenture and the Securities of such series;
 
    (2) The Company has delivered to the Trustee an Opinion of Counsel based on
  the fact that (x) the Company has received from, or there has been published
  by, the Internal Revenue Service a ruling, or (y) since the date hereof, there
  has been a change in the applicable federal income tax law, in either case to
  the effect that, and such opinion 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 and defeasance and will be
  subject to federal income tax on the same amount and in the same manner and at
  the same times, as would have been the case if such deposit and defeasance had
  not occurred;
 
    (3) If the Securities are to be redeemed prior to Stated Maturity (other
  than from mandatory sinking fund payments or analogous payments), notice of
  such redemption shall have been duly given pursuant to this Indenture or
  provision therefor satisfactory to the Trustee shall have been made;
 
    (4) No Default or Event of Default shall have occurred and be continuing on
  the date of such deposit; and
 
    (5) The Company has delivered to the Trustee an Officer's Certificate and an
  Opinion of Counsel, each stating that all conditions precedent provided for
  relating to the defeasance contemplated by this provision have been complied
  with.
 
  For this purpose, such defeasance means that the Company and any other obligor
upon the Securities of such series shall be deemed to have paid and
<PAGE>   87
 
                                       79
 
discharged the entire debt represented by the Securities of such series, which
shall thereafter be deemed to be "Outstanding" only for the purposes of Section
1304 and the rights and obligations referred to in clauses (i) through (vi),
inclusive, of the first paragraph of this Section, and to have satisfied all its
other obligations under the Securities of such series and this Indenture insofar
as the Securities of such series are concerned.
 
  SECTION 1303. Covenant Defeasance.
 
  The Company and any other obligor, if any, shall be released on the 91st day
after the date of the deposit referred to in clause (1) below from its
obligations under Sections 704, 801, 1005, 1006 and 1007 with respect to the
Securities of any series on and after the date the conditions set forth below
are satisfied (hereinafter, "covenant defeasance"), and the Securities of such
series shall thereafter be deemed to be not "Outstanding" for the purposes of
any request, demand, authorization, direction, notice, waiver, consent or
declaration or other action or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
Outstanding for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to the Securities of such series, the
Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such Section, whether directly or
indirectly by reason of any reference elsewhere herein to such Section or by
reason of any reference in such Section to any other provision herein or in any
other document and such omission to comply shall not constitute a Default or an
Event of Default under Section 501, but, except as specified above, the
remainder of this Indenture and the Securities of such series shall be
unaffected thereby. The following shall be the conditions to application of this
Section 1303:
 
    (1) The Company has irrevocably deposited or caused to be deposited 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 the Securities of such series, (i) cash in an
  amount, or (ii) in the case of any series of Securities the payments on which
  may only be made in legal coin or currency of the United States, U.S.
  Government Obligations, maturing as to principal and interest at such times
  and in such amounts as will insure the availability of cash, or (iii) a
  combination thereof, 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 (A) the principal and interest and
  premium, if any, on all Securities of such series on each date that such
  principal,
<PAGE>   88
 
                                       80
 
  interest or premium, if any, is due and payable or on any Redemption Date
  established pursuant to clause (2) below, and (B) any mandatory sinking fund
  payments on the day on which such payments are due and payable in accordance
  with the terms of the Indenture and the Securities of such series;
 
    (2) If the Securities are to be redeemed prior to Stated Maturity (other
  than from mandatory sinking fund payments or analogous payments), notice of
  such redemption shall have been duly given pursuant to this Indenture or
  provision therefor satisfactory to the Trustee shall have been made;
 
    (3) No Default or Event of Default shall have occurred and be continuing on
  the date of such deposit;
 
    (4) The Company shall have delivered to the Trustee an Opinion of Counsel
  which 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 and covenant defeasance and will be subject to federal income tax
  on the same amount and in the same manner and at the same times, as would have
  been the case if such deposit and covenant defeasance had not occurred; and
 
    (5) The Company shall have delivered to the Trustee an Officer's Certificate
  stating that all conditions precedent provided for relating to the covenant
  defeasance contemplated by this provision have been complied with.
 
  SECTION 1304. Application by Trustee of Funds Deposited for Payment of
Securities.
 
  Subject to the provisions of the last paragraph of Section 1003, all moneys or
U.S. Government Obligations deposited with the Trustee pursuant to Section 1302
or 1303 (and all funds earned on such moneys or U.S. Government Obligations)
shall be held in trust and applied by it to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent),
to the Holders of the particular Securities of such series for the payment or
redemption of which such moneys have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest; but such money
need not be segregated from other funds except to the extent required by law.
Subject to Sections 1302 and 1303, the Trustee promptly shall pay to the Company
upon request any excess moneys held by them at any time.
<PAGE>   89
 
                                       81
 
  SECTION 1305. Repayment to Company.
 
  The Trustee and any Paying Agent promptly shall pay or return to the Company
upon Company Request any money and U.S. Government Obligations held by them at
any time that are not required for the payment of the principal of and any
interest on the Securities of any series for which money or U.S. Government
Obligations have been deposited pursuant to Section 1302 or 1303.
 
  The provisions of the last paragraph of Section 1003 shall apply to any money
held by the Trustee or any Paying Agent under this Article that remains
unclaimed for two years after the Maturity of any series of Securities for which
money or U.S. Government Obligations have been deposited pursuant to Section
1302 or 1303.
 
  This instrument may be executed with counterpart signature pages or in any
number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the

                           7 1/2% DEBENTURE DUE 2017
 
  This Security is one of a duly authorized issue of securities of the Company
(the "Securities"), issued and to be issued in one or more series under an
Indenture dated as of March 4, 1997 (the "Indenture"), between the Company and
The Chase Manhattan Bank, as Trustee (the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. As
provided in the Indenture, the Securities may be issued in one or more series,
which different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest, if any, at different rates, may be
subject to different redemption provisions, if any, may be subject to different
sinking, purchase or analogous funds, if any, may be subject to different
covenants and Events of Default and may otherwise vary as in the Indenture
provided or permitted. This Security is one of the series designated on the face
hereof, limited in aggregate principal amount to U.S.$300,000,000.
 
  The Securities of this series are not redeemable prior to Stated Maturity.
 
  If an Event of Default with respect to Securities of this series shall occur
and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.
 
  The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all series to be affected (voting as one class). The
Indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all affected series
(voting as one class), on behalf of the Holders of all Securities of such
series, to waive compliance by the Company with certain provisions of the
Indenture. The Indenture permits, with certain exceptions as therein provided,
the Holders of a majority in principal amount of Securities of all affected
series then Outstanding (voting as a single class) to waive past defaults under
the
<PAGE>   10
 
                                        5
 
Indenture with respect to such Securities and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.
 
  As provided in and subject to the provisions of the Indenture, the Holder of
this Security shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of all affected series at the time Outstanding (treated as a
single class) shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity and the Trustee shall not have received from the
Holders of a majority in principal amount of Securities of this series at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or interest hereon on or after the respective due
dates expressed herein.
 
  No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Security at the times, place(s) and rate, and in the coin or currency, herein
prescribed.
 
  This Global Security or portion hereof may not be exchanged for Definitive
Securities of this series except in the limited circumstances provided in the
Indenture.
 
  The holders of beneficial interests in this Global Security will not be
entitled to receive physical delivery of Definitive Securities except as
described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture.
 
  The Securities of this series are issuable only in registered form without
coupons in denominations of U.S. $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
<PAGE>   11
 
                                        6
 
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.
 
  No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.
 
  Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.
 
  No recourse under or upon any obligation, covenant or agreement of or
contained in the Indenture or of or contained in any Security, or for any claim
based thereon or otherwise in respect thereof, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor Person, either directly or through
the Company or any successor Person, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment, penalty or
otherwise; it being expressly understood that all such liability is hereby
expressly waived and released by the acceptance hereof and as a condition of,
and as part of the consideration for, the Securities and the execution of the
Indenture.
 
  The Indenture provides that the Company (a) will be discharged from any and
all obligations in respect of the Securities (except for certain obligations
described in the Indenture), or (b) need not comply with certain restrictive
covenants of the Indenture, in each case if the Company deposits, in trust, with
the Trustee money or U.S. Government Obligations (or a combination thereof)
which through the payment of interest thereon and principal thereof in
accordance with their terms will provide money, in an amount sufficient to pay
all the principal of and interest on the Securities, but such money need not be
segregated from other funds except to the extent required by law.
 
  THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK.
 
  All terms used in this Security which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.

                             7% DEBENTURE DUE 2027
 
  This Security is one of a duly authorized issue of securities of the Company
(the "Securities"), issued and to be issued in one or more series under an
Indenture dated as of March 4, 1997 (the "Indenture"), between the Company and
The Chase Manhattan Bank, as Trustee (the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. As
provided in the Indenture, the Securities may be issued in one or more series,
which different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest, if any, at different rates, may be
subject to different redemption provisions, if any, may be subject to different
sinking, purchase or analogous funds, if any, may be subject to different
covenants and Events of Default and may otherwise vary as in the Indenture
provided or permitted. This Security is one of the series designated on the face
hereof, limited in aggregate principal amount to U.S.$300,000,000.
 
  The Holder of this Security may elect to have this Security (or any portion
hereof that is an integral multiple of $1,000) repaid on March 15, 2007 (or, if
such day is not a Business Day, the next succeeding Business Day), at a
repayment price equal to the principal amount of this Security (or such portion
hereof), together with accrued and unpaid interest thereon to the date of
repayment. In order for the Holder of this Security to make this election, the
Company must receive at its office or agency in New York, New York, during the
period beginning on January 15, 2007 and ending at 5:00 p.m. (New York City
time) on February 15, 2007 (or, if such day is not a Business Day, the next
succeeding Business Day) this Security with the form entitled "Option to Elect
Repayment on March 15, 2007" below duly completed. Any such election received
during the period beginning on January 15, 2007 and ending at 5:00 p.m. (New
York City time) on February 15, 2007 shall be irrevocable. All questions as to
the validity, form, eligibility (including time of receipt) and acceptance of
this Security for repayment will be determined by the Company whose
determination shall be final and binding. Failure of the Company to repay this
Security (or such portion hereof) when required shall constitute an
<PAGE>   10
 
                                        5
 
Event of Default with respect to the 7% Debentures Due 2027 only and not with
respect to any other series of Securities. If applicable, the Company will
comply with the requirements of Rule 14e-1 under the Securities Exchange Act of
1934, as amended, in connection with any election by Holders to have the
Securities repaid on March 15, 2007 (or, if such day is not a Business Day, the
next succeeding Business Day).
 
  The Securities of this series are redeemable, upon not less than 30 nor more
than 60 days' notice by mail, as a whole or in part, at the option of the
Company at any time and from time to time after March 15, 2007 at a redemption
price equal to greater of (i) 100% of the principal amount of such Securities
and (ii) as determined by an Independent Investment Banker, the sum of the
present values of the remaining scheduled payments of principal and interest
hereon discounted to the date of redemption on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
together, in each case, with accrued and unpaid interest to such Redemption
Date, but interest installments whose Stated Maturity is on or prior to such
Redemption Date will be payable to the Holders of such Securities, or one or
more Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the Indenture.
 
  "Adjusted Treasury Rate" means, with respect to any Redemption Date, the rate
per annum equal to the semi-annual 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 date of redemption, plus .15%.
 
  "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 Securities of this series 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 securities.
 
  "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.
<PAGE>   11
 
                                        6
 
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 date of redemption,
after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such Reference Treasury Dealer
Quotations.
 
  "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by the Trustee after consultation with the Company.
 
  "Reference Treasury Dealer" means each of Donaldson, Lufkin & Jenrette
Securities Corporation, Morgan Stanley & Co. Incorporated, Chase Securities Inc.
and Citicorp Securities, Inc. and their respective successors; provided,
however, that if any of the foregoing shall not 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.
 
  "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day preceding such Redemption Date.
 
  In the event of redemption of this Security in part only, a new Security or
Securities of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder hereof upon the cancellation hereof.
 
  If an Event of Default with respect to Securities of this series shall occur
and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.
 
  The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all series to be affected (voting as one class). The
Indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all affected series

series,
<PAGE>   12
 
                                        7
 
to waive compliance by the Company with certain provisions of the Indenture. The
Indenture permits, with certain exceptions as therein provided, the Holders of a
majority in principal amount of Securities of all affected series then
Outstanding (voting as a single class) to waive past defaults under the
Indenture with respect to such Securities and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.
 
  As provided in and subject to the provisions of the Indenture, the Holder of
this Security shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of all affected series at the time Outstanding (treated as a
single class) shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity and the Trustee shall not have received from the
Holders of a majority in principal amount of Securities of this series at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or interest hereon on or after the respective due
dates expressed herein.
 
  No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Security at the times, place(s) and rate, and in the coin or currency, herein
prescribed.
 
  This Global Security or portion hereof may not be exchanged for Definitive
Securities of this series except in the limited circumstances provided in the
Indenture.
 
  The holders of beneficial interests in this Global Security will not be
entitled to receive physical delivery of Definitive Securities except as
described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture.

                                        8
 
  The Securities of this series are issuable only in registered form without
coupons in denominations of U.S. $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.
 
  No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.
 
  Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.
 
  No recourse under or upon any obligation, covenant or agreement of or
contained in the Indenture or of or contained in any Security, or for any claim
based thereon or otherwise in respect thereof, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor Person, either directly or through
the Company or any successor Person, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment, penalty or
otherwise; it being expressly understood that all such liability is hereby
expressly waived and released by the acceptance hereof and as a condition of,
and as part of the consideration for, the Securities and the execution of the
Indenture.
 
  The Indenture provides that the Company (a) will be discharged from any and
all obligations in respect of the Securities (except for certain obligations
described in the Indenture), or (b) need not comply with certain restrictive
covenants of the Indenture, in each case if the Company deposits, in trust, with
the Trustee money or U.S. Government Obligations (or a combination thereof)
which through the payment of interest thereon and principal thereof in
accordance with their terms will provide money, in an amount sufficient to pay
all the principal of and interest on the Securities, but such money need not be
segregated from other funds except to the extent required by law.

                           7 5/8% DEBENTURES DUE 2037
 
  This Security is one of a duly authorized issue of securities of the Company
(the "Securities"), issued and to be issued in one or more series under an
Indenture dated as of March 4, 1997 (the "Indenture"), between the Company and
The Chase Manhattan Bank, as Trustee (the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. As
provided in the Indenture, the Securities may be issued in one or more series,
which different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest, if any, at different rates, may be
subject to different redemption provisions, if any, may be subject to different
sinking, purchase or analogous funds, if any, may be subject to different
covenants and Events of Default and may otherwise vary as in the Indenture
provided or permitted. This Security is one of the series designated on the face
hereof, limited in aggregate principal amount to U.S.$300,000,000.
 
  The Securities of this series are not redeemable prior to Stated Maturity.
 
  If an Event of Default with respect to Securities of this series shall occur
and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.
 
  The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all series to be affected (voting as one class). The
Indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all affected series
(voting as one class), on behalf of the Holders of all Securities of such
series, to waive compliance by the Company with certain provisions of the
Indenture. The Indenture permits, with certain exceptions as therein provided,
the Holders of a majority in principal amount of Securities of all affected
series
<PAGE>   10
 
                                        5
 
then Outstanding (voting as a single class) to waive past defaults under the
Indenture with respect to such Securities and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.
 
  As provided in and subject to the provisions of the Indenture, the Holder of
this Security shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of all affected series at the time Outstanding (treated as a
single class) shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity and the Trustee shall not have received from the
Holders of a majority in principal amount of Securities of this series at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or interest hereon on or after the respective due
dates expressed herein.
 
  No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Security at the times, place(s) and rate, and in the coin or currency, herein
prescribed.
 
  This Global Security or portion hereof may not be exchanged for Definitive
Securities of this series except in the limited circumstances provided in the
Indenture.
 
  The holders of beneficial interests in this Global Security will not be
entitled to receive physical delivery of Definitive Securities except as
described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture.
 
  The Securities of this series are issuable only in registered form without
coupons in denominations of U.S. $1,000 and any integral multiple thereof. As
<PAGE>   11
 
                                        6
 
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.
 
  No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.
 
  Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.
 
  No recourse under or upon any obligation, covenant or agreement of or
contained in the Indenture or of or contained in any Security, or for any claim
based thereon or otherwise in respect thereof, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor Person, either directly or through
the Company or any successor Person, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment, penalty or
otherwise; it being expressly understood that all such liability is hereby
expressly waived and released by the acceptance hereof and as a condition of,
and as part of the consideration for, the Securities and the execution of the
Indenture.
 
  The Indenture provides that the Company (a) will be discharged from any and
all obligations in respect of the Securities (except for certain obligations
described in the Indenture), or (b) need not comply with certain restrictive
covenants of the Indenture, in each case if the Company deposits, in trust, with
the Trustee money or U.S. Government Obligations (or a combination thereof)
which through the payment of interest thereon and principal thereof in
accordance with their terms will provide money, in an amount sufficient to pay
all the principal of and interest on the Securities, but such money need not be
segregated from other funds except to the extent required by law.
 
  THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK.
 
  All terms used in this Security which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.
