NORCEN ACQUISITION
 
     On March 6, 1998, the Company, through its wholly owned subsidiary Union
Pacific Resources Inc. ('UPRI'), completed the purchase (the 'Norcen
Acquisition') of all the outstanding common shares (the 'Norcen Shares') of
Norcen pursuant to a cash tender offer and a compulsory acquisition procedure,
making Norcen an indirect, wholly owned subsidiary of the Company. The Company
purchased the Norcen Shares for C$19.80 per share ($13.65), or $2.6 billion in
total, and assumed all of Norcen's outstanding net debt of approximately $1
billion, giving the overall transaction a $3.6 billion value.
 
     The Norcen Acquisition was paid for in cash and financed by the Company
with the issuance of commercial paper, supported by a $2.7 billion 364 Day

Competitive Advance/Revolving Credit Agreement, dated March 2, 1998, by and
among the Company, the lenders named therein and the Bank of Montreal, as
syndication agent and The Chase Manhattan Bank, as administrative agent (the
'Norcen Facility').
 
     Norcen is a major Canadian oil and gas exploration and development company
with primary operations in western Canada, the Gulf of Mexico, Guatemala and
Venezuela. In addition, Norcen owns 10 percent of Superior Propane Inc., the
largest propane marketer in Canada.

PLANNED DIVESTITURE
 
     On April 27, 1998, the Company announced that as part of its previously
announced deleveraging program it plans to sell approximately $600 million of
non-core exploration and production properties by the end of 1998. In addition,
the Company announced that it plans to explore opportunities to monetize its
gathering, processing and marketing business.
 
                                USE OF PROCEEDS
 
     The aggregate net proceeds from the sale of the Securities offered hereby
are estimated to be approximately $1,012,392,750. All of such net proceeds will
be used to repay outstanding commercial paper of the Company. As of April 30,
1998, the weighted average interest rate on all outstanding commercial paper
borrowings of the Company was 5.82% per annum with maturities varying from 1 to
120 days.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
     The table below sets forth the ratio of earnings to fixed charges for the
periods indicated and pro forma ratio of earnings to fixed charges for the year
ended December 31, 1997, adjusted to give effect to the Norcen Acquisition as if
such transaction had occurred on January 1, 1997. The ratio of earnings to fixed
charges has been computed on a total enterprise basis. Earnings represent income
before the cumulative effect of accounting changes less equity in undistributed
earnings of unconsolidated affiliates, plus income taxes and fixed charges.
Fixed charges represent interest, amortization of debt discount and expense, and
the estimated interest portion of rental charges.

(1) Includes the plant share of equity gas processed (natural gas and natural
    gas liquids, as appropriate, earned by gas processing facilities through the
    processing of the Company's equity production).
(2) Calculated using the ratio of one Bbl to six Mcf.
(3) The reserve data set forth in this Prospectus Supplement or incorporated by
    reference herein represent only estimates. There are numerous uncertainties
    inherent in estimating quantities of proved reserves and in projecting
    future rates of production and timing of development expenditures, including
    many factors beyond the control of the Company. Reserve engineering is a
    subjective process of estimating underground accumulations of crude oil and
    natural gas that cannot be measured in an exact manner, and the accuracy of

    any reserve estimate is a function of the quality of available data and of
    engineering and geological interpretation and judgment. Accordingly, reserve
    estimates often differ from the quantities of oil and gas that are
    ultimately recovered.
(4) In accordance with the Securities and Exchange Commission's guidelines, the
    Company's estimate of the standardized measure of discounted future net cash
    flows from the Company's properties has been made using oil and natural gas
    sales priced in effect as of the date of such estimate and have been held
    constant throughout the life of the properties except where such guidelines
    permit alternate treatment, including the use of fixed and determinable
    contractual price escalations. Prices for natural gas, natural gas liquids
    and crude oil are subject to substantial fluctuations as a result of
    numerous other factors. The standardized measure of discounting future net
    cash flows relating to proved reserves should not be construed as the
    current market value of estimated natural gas, natural gas liquids and crude
    oil reserves.
(5) Pro forma information is not available for standardized measure of
    discounted future net cash flows.

                                  THE COMPANY
 
GENERAL
 
     The Company is engaged primarily in the exploration for and the development
and production of natural gas, natural gas liquids and crude oil in several
major producing basins in the United States, Canada, Guatemala and Venezuela.
The Company emphasizes natural gas in its exploration and production activities

and also owns and operates significant assets, in proximity to its principal
producing properties, dedicated to 'gas value chain' activities, which consist
of the gathering, processing, transportation and marketing of natural gas and
natural gas liquids. In addition, the Company engages in the hard minerals
business through a nonoperated joint venture and royalty interests in several
coal and trona (natural soda ash) mines located on lands within and adjacent to
its Land Grant (hereinafter defined) holdings in Wyoming. The 'Land Grant'
consists of land granted by the Federal government to a predecessor and former
affiliate of the Company in the mid-1800s which passes through the states of
Colorado and Wyoming and into Utah. The Company has fee ownership of the mineral
rights under approximately 7.9 million acres in the Land Grant.
 
BUSINESS STRATEGY
 
     The Company is primarily in the business of developing and exploring for
natural gas and crude oil in its core geographic areas. The Company's strategy
is to focus on its core geographic areas in which the Company can apply
economies of scale, its operating experience and its expertise in advanced
drilling and completion technologies, as well as, to increase margins through
reductions in drilling and operating costs. This focus generates increased
production and enhanced well results. The Company also increases its drill site
inventory through exploration, farm-in agreements and acquisitions of properties
and companies. With the Norcen Acquisition, the Company added several new core
operating areas and added production and exploration opportunities in the Gulf
of Mexico, Canada, Guatemala and Venezuela. The Company maintains a high working
interest in its core areas and typically serves as operator, which allows it to
control the timing and cost of exploration and development activities and
enhances the Company's ability to apply its expertise to these properties.
 
     The Company strives to improve its service to its customers and other
constituencies, including its partners, governmental agencies, interest owners,
vendors, employees, bankers, and producers. The Company believes that providing
each customer with a high level of service will differentiate the Company from
its competition and provide the Company with a competitive advantage.
 
     On March 6, 1998, the Company completed the Norcen Acquisition. Norcen is a
major Canadian oil and gas exploration and production company with primary
operations in western Canada, the Gulf of Mexico, Guatemala and Venezuela. The
acquisition of Norcen significantly increases the Company's drill site inventory
and expands the Company's operations beyond the Company's historically domestic
focus. The Company intends to apply its superior drilling expertise to Norcen's
property base which the Company believes is of high quality and in many cases
under-exploited. For additional information including information regarding the
impact of the Norcen Acquisition on the Company's capitalization, see 'Recent
Developments--Norcen Acquisition', 'Capitalization' and 'Selected Historical and
Pro Forma Financial Information'.
 
     Norcen's properties are located in four major areas which include western
Canada, the Gulf of Mexico, Guatemala and Venezuela. In addition, Norcen owns
producing properties in Argentina and offshore Australia. As of December 31,
1997, Norcen's proved reserves and production in these areas, on a percentage
basis, are as follows:

PRODUCING PROPERTIES OPERATIONS
 
     Following the Norcen Acquisition, the Company's oil and gas activities
currently are concentrated in eight core geographic areas: (1) the Austin Chalk
trend in Texas and Louisiana, managed by the Austin Chalk business unit, (2) the
western portion of the Land Grant Area in Wyoming, Utah and Colorado with
additional operations primarily in Kansas, managed by the Rockies/Plains
business unit, (3) the onshore Gulf Coast area, including southern Texas and
southern Louisiana, managed by the Gulf Onshore business unit, (4) the offshore
Gulf of Mexico area, managed by the Gulf Offshore business unit, (5) eastern
Texas, managed by the East Texas business unit, (6) western Texas, managed by
the West Texas business unit, (7) western Canada, including northeastern British
Columbia and Alberta, managed by the Canada business unit and (8) other
international operations, managed by the International business unit.
 
     Natural gas and natural gas liquids constituted 81% of the Company's total
proved reserves of 4.1 Tcfe as of December 31, 1997, and 83% of the Company's
sales volumes of 1.9 Bcfed for the year ended December 31, 1997. On a pro forma
basis, natural gas and natural gas liquids constituted 69% of the Company's
proved reserves of 7.3 Tcfe as of December 31, 1997 and 70% of the Company's
sales volumes of 2.5 Bcfed. Approximately 69% of the Company's production from
producing properties during this same period was attributable to
Company-operated properties.
 
     The following table sets forth certain proved reserve and production
information as of and for the year ended December 31, 1997 with respect to each
of the Company's business units as adjusted to give effect to the Norcen
Acquisition. The Company considers such estimates to be reasonable; however,
there are numerous uncertainties inherent in estimated quantities of proved
reserves, including many factors beyond the control of the Company. Reserve
engineering is a subjective process which is dependent on the quality of
available data and on engineering and geological interpretation and judgment.
Such reserve estimates are subject to change over time, as additional
information becomes available.

GATHERING, PROCESSING AND MARKETING OPERATIONS
 
  Processing
 
     As of December 31, 1997, the Company owned interests in 24 natural gas
processing plants, 19 of which it operates, with a current throughput capacity
of 3.4 Bcfd (1.8 Bcfd net to the Company). In 1997, the Company expanded its
gathering, processing and marketing business unit with the purchase of Highlands
Gas Corporation ('Highlands') which included three gas processing plants. The
Company was able to add approximately 300 Mmcfd throughput capacity with the
purchase of Highlands, start-up of the new Masters Creek plant in Louisiana and
the expansion of the Patrick Draw plant in Wyoming. Aggregate throughput of the
Company's gas processing plants for the year ended December 31, 1997 averaged
83% of the plants' aggregate design capacity. For the year ended December 31,
1997, production of natural gas liquids attributable to the Company's ownership
interest in gas processing facilities averaged approximately 41.7 MBbld.
 
  Gathering
 
     The Company invests in gathering systems and natural gas, natural gas
liquids and crude oil pipelines. Some of the Company's more significant
investments in pipelines and gathering systems, include: (1) the Company's 50%
interest in the Black Lake Pipeline, a 317 mile pipeline in Louisiana which
transports natural gas liquids from the Austin Chalk area to markets on the Gulf

Coast; (2) the Company's 90% interest in the Panola Pipeline in the eastern
Texas area; (3) the Company's 100% interest in the Sonora/Fin Tex NGL Pipeline
which serves the western Texas area; (4) the Company's 55% interest in the
Ferguson-Burleson County Gas Gathering System ('Ferguson-Burleson'), which
serves the Giddings area of the Austin Chalk area; (5) the Company's 99%
interest in the Overland Trail Transmission Company pipeline, a 305 mile
pipeline, serving the Green River Basin in Wyoming; and (6) the Company's 100%
interest in the Wahsatch Gathering System, a sour gas pipeline serving the
Overthrust area in Wyoming. In addition, the Company generally owns extensive
gathering systems behind each of its natural gas processing plants which it uses
to transport unprocessed gas from producing wells to the inlet of the plants.
 
  Marketing
 
     In 1997, the Company, primarily through Union Pacific Fuels, Inc. ('UP
Fuels'), sold approximately 2 Bcfd of natural gas (about 57% of which
represented the Company's equity production), 145 MBbld of natural gas liquids
(including 73 MBbld of third party liquids) and 68 MBbld of crude oil and
condensate (including 15 MBbld of third party crude oil and condensate).
 
                                      S-13
<PAGE>
     In addition, UP Fuels provides storage and transportation services in
certain natural gas supply and market areas and manages the Company's market
hubs in eastern Texas and the Land Grant area. The Company has a diverse
customer base for natural gas, which includes local distribution companies,
power generation facilities, pipelines, industrial plants and other wholesale
marketing companies. The natural gas liquids customers that UP Fuels targets are
wholesalers, industrial end users and traders. UP Fuels prefers to sell its
natural gas liquids in local markets, which generally offer more attractive
pricing. Natural gas liquids not sold locally are shipped from the various
plants by pipelines to the Company's partially owned fractionators in Mt.
Belvieu, Texas. To maximize profits, UP Fuels sells crude oil directly to
refiners whenever possible. UP Fuels also exchanges or sells the crude oil
volumes to major trading locations, where the crude oil is sold to both refiners
and marketers.

(1) Includes properties leased to five soda ash producers, estimated to contain
    resources sufficient to support over 30 years of production at current
    production levels.
(2) The Company leases coal resources to six operating mines. In 1997, 58% of
    the Company's coal royalties were attributable to a single mine which
    supplies an adjacent power station that is owned and operated by affiliates
    of the mine owners.
(3) Represents a 49% interest in OCI Wyoming LP, a nonoperated joint venture.
(4) Represents the Company's 50% nonoperating interest in Black Butte Coal
    Company. Of this amount, $59.3 million is attributable to a single coal
    supply contract, the financially beneficial terms of which terminate at the
    end of year 2000.
 
     The Company's low sulfur coal deposits compete with other western United
States coals for industrial and utility boiler markets. At current coal pricing
and extraction cost levels, however, most of the coal deposits are not economic
to extract, except for sale to local markets. As a result, there are currently
limited opportunities for new coal mine development in the Land Grant.
 
     The world's largest deposit of trona ore, constituting 90% of the world's
known trona resources, is located in the Green River Basin in southwestern
Wyoming. Approximately 40% of this trona deposit lies within the Land Grant and
is therefore owned by the Company. Natural soda ash, which is produced by
refining trona ore, is used primarily in the production of glass for containers
and flat glass, in the paper and water treatment industries and in the
manufacture of certain chemicals and detergents. Natural soda ash production
from Wyoming has increased to 30% of the world's soda ash supply with the

remainder principally from synthetic processes. As a result of the increase in
the worldwide demand for soda ash, the Company, along with its partner Oriental
Chemical Industries, Inc. ('OCI'), plans to expand the OCI Wyoming LP soda ash
facility by 950,000 tons per year, from the plant's current nameplate capacity
of 2.3 million tons per year, by 1999. For the year ended December 31, 1997, the
Company invested an additional $19.7 million in OCI Wyoming LP and guaranteed
49% of a $100 million credit facility to finance the soda ash facility
expansion.

     There is no provision for a sinking fund for the Securities.
 
DEFEASANCE
 
     Under certain circumstances, the Company will be deemed to have discharged
the entire indebtedness on all of the outstanding Securities by defeasance. See

'Description of Debt Securities--Defeasance of the Indenture and Debt
Securities' in the accompanying Prospectus for a description of the terms of any
such defeasance and the tax consequences thereof.
 
BOOK-ENTRY SYSTEM
 
     Eash series of the Securities will initially be represented by one or more
global securities (each a 'Global Security') deposited with DTC and registered
in the name of a nominee of DTC, except as set forth below. The settlement of
transactions with respect to each Global Security will be facilitated through
electronic computerized book-entry changes in participants' accounts, thereby
eliminating the physical movement of Security certificates. The Securities will
be available for purchase in denominations of $1,000 and integral multiples
thereof in book-entry form only. Unless and until certificated Securities are
issued under the limited circumstances described below, no beneficial owner of a
Security shall be entitled to receive a definitive certificate representing a
Security. So long as DTC or any successor depositary (the 'Depositary') or its
nominee is the registered owner of a Global Security, the Depositary or such
nominee, as the case may be, will be considered to be the sole owner or holder
of the Securities represented thereby for all purposes. Unless and until it is
exchanged in whole or in part for the Securities represented thereby, a Global
Security may not be transferred except as a whole by the Depositary to a nominee
of the Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by the Depositary or any nominee to a
successor depositary or any nominee of such successor.
 
     So long as Securities are represented by a Global Security, all payments of
principal and interest with respect thereto will be made to the Depositary or
its nominee (or a successor), as the case may be, as the sole registered owner
of the Global Security representing such Securities.
 
     The Company expects that the Depositary or its nominee, upon receipt of any
payment of principal or interest in respect of a Global Security representing
Securities, will credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such Global Security as shown on the records of the Depositary or such
nominee.
 
     If DTC is at any time unwilling, unable or ineligible to continue as
depositary for a Global Security and a successor depositary is not appointed by
the Company within 90 days, the Company will issue certificated Securities in
definitive form in exchange for such Global Security. In addition, the Company
may at any time determine not to have the Securities represented by a Global
Security, and, in such event, will issue certificated Securities in definitive
form in exchange for such Global Security. In either instance, an owner of a
beneficial interest in a Global Security will be entitled to physical delivery
of certificated Securities in definitive form equal in principal amount to such
beneficial interest in such Global Security and to have such certificated
Securities registered in its name. Certificated Securities so issued in
definitive form will be issued in denominations of $1,000 and integral multiples
thereof and will be issued in registered form only, without coupons.

     See 'Description of Debt Securities' in the accompanying Prospectus for
additional information concerning the Debt Securities, the Indenture and the
book-entry system.
 
SAME DAY SETTLEMENT AND PAYMENT
 
     Settlement for the Securities will be made by the Underwriters (as
hereinafter defined) in immediately available funds. All payments of principal
and interest to the Depositary will be made by the Company in immediately
available funds.
 
     Secondary trading in notes and debentures of corporate issuers is generally
settled in clearinghouse or next-day funds. In contrast, the Securities will
trade in the DTC's Same-Day Funds Settlement System until maturity, and, to the
extent that secondary market trading activity in the Securities is effected
through the facilities of DTC, such secondary market trading activity in the
Securities will settle in immediately available funds. No assurance can be given
as to the effect, if any, of settlements in immediately available funds on
trading activity in the Securities.
 
                                  UNDERWRITING

</TABLE>
 
     The Underwriters are obligated to take and pay for all of the Securities if
any are taken. In the event of default by any Underwriter, the Underwriting
Agreement provides that, in certain circumstances, purchase commitments of the
non-defaulting Underwriter may be increased or the Underwriting Agreement may be
terminated.
 
     The Company has been advised by the Underwriters that they propose to offer
the Securities to the public initially at the respective offering prices set
forth on the cover page of this Prospectus Supplement and to certain dealers at
such prices less a concession not in excess of 0.375% of the principal amount of
the 2005 Notes, 0.400% of the principal amount of the 2008 Notes, 0.500% of the
principal amount of the 2018 Debentures and 0.500% of the principal amount of
the 2028 Debentures and that the Underwriters and such dealers may allow a
discount not in excess of 0.25% of the principal amount of the 2005 Notes, 0.25%
of the principal amount of the 2008 Notes, 0.25% of the principal amount of the
2018 Debentures and 0.25% of the principal amount of the
 
                                      S-18
<PAGE>
2028 Debentures on sales to other dealers. After the initial public offering,
the public offering prices and concessions and discount to dealers may be
changed by the Underwriters.
 
     The Company does not intend to apply for listing of the Securities on a
national securities exchange, but has been advised by the Underwriters that they
presently intend to make a market in each of the Securities, as permitted by
applicable laws and regulations.
 
     The Underwriters are not obligated, however, to make a market in each of
the Securities and any such market making may be discontinued at any time at the
sole discretion of the Underwriters. Accordingly, no assurance can be given as
to the liquidity of, or the existence of trading markets for, the Securities.
 
     The Underwriting Agreement provides that the Company has agreed to
indemnify the Underwriters against certain liabilities, including civil
liabilities under the Securities Act of 1933, as amended, or to contribute to
payments which the Underwriters may be required to make in respect thereof.
 
     Certain of the Underwriters or their affiliates engage in transactions with
and perform services, including commercial and investment banking and hedging
services, for the Company and certain of its affiliates in the ordinary course
of business. The Chase Bank of Texas, N.A. (formerly Texas Commerce Bank
National Association), the Trustee, is an affiliate of Chase Securities Inc.
 
     The Underwriters may engage in over-allotment, stabilizing transactions,
short covering transactions and penalty bids in accordance with Rule 104 of
Regulation M under the Exchange Act. Over-allotment involves sales in excess of
the offering size, which creates a short position for the Underwriters.
Stabilizing transactions permit bids to purchase the underlying security so long
as the stabilizing bids do not exceed a specified maximum. Short covering
transactions involve purchases of the Securities in the open market after the
distribution has been completed in order to cover short positions. Penalty bids

permit the Underwriters to reclaim a selling concession from a dealer when the
Securities originally sold by such dealer are purchased in a covering
transaction to cover short positions. Such over-allotment stabilizing
transactions, covering transactions and penalty bids may cause the price of a
'covered security' to be higher than it would otherwise be in the absence of
such transactions.
 
                          FORWARD-LOOKING INFORMATION
 
     Certain information included and incorporated by reference in this
Prospectus Supplement represents, and other materials filed or to be filed by
the Company with the Commission (as well as information included in oral
statements or other written statements made or to be made by the Company)
contain or will contain or include, forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended (the
'Securities Act'), and Section 21E of the Exchange Act. Such forward-looking
statements may be or may concern, among other things, capital expenditures,
drilling activity, acquisitions and dispositions, and conditions and
transactions related thereto, development activities, cost savings efforts,
production activities and volumes, hydrocarbon reserves, hydrocarbon prices,
hedging activities and the results thereof, liquidity, regulatory matters and
competition.
 
     Such forward-looking information is based upon management's current plans,
expectations, estimates and assumptions and is subject to a number of
uncertainties and risks that could significantly affect current plans,
anticipated actions, the timing of such actions and the Company's financial
condition and results of operations. The risks and uncertainties associated with
such forward-looking statements, which are explained in greater detail in the
Company's Annual Report on Form 10-K for the year ended December 31, 1997,
include generally the volatility of hydrocarbon prices and hydrocarbon-based
financial derivatives prices; basis risk and counterpart credit risk in
executing hydrocarbon price risk management activities; economic, political,
judicial and regulatory developments; competition in the industry, as well as
competition from other sources of energy; the economics of producing certain
reserves; hydrocarbon demand and supply; the ability to find or acquire and
develop reserves of natural gas and crude oil; and the actions of customers and
competitors. As a consequence, actual results may differ materially from
expectations, estimates or assumptions expressed in any forward-looking
statements made by or on behalf of the Company.

     The financial statements incorporated by reference in this Prospectus
Supplement and accompanying Prospectus dated March 17, 1997, from the Company's
Annual Report on Form 10-K for the year ended December 31, 1997 and the
financial statements from which the Selected Historical Financial Information
included in this Prospectus Supplement have been derived, have been audited by
Deloitte & Touche LLP, independent auditors, as stated in their report, which is
incorporated herein by reference. Such financial statements and Selected
Historical Financial Information have been included in this Prospectus
Supplement in reliance upon the report of such firm given upon their authority

as experts in accounting and auditing.
 
     With respect to the unaudited interim financial information for the three
months ended March 31, 1997, which is incorporated herein by reference, Deloitte
& Touche LLP have applied limited procedures in accordance with professional
standards for a review of such information. However, as stated in their report
included in the Company's Quarterly Report on form 10-Q for the three months
ended March 31, 1997, and incorporated by reference herein, they did not audit
and they do not express an opinion on that information. Accordingly, the degree
of reliance on their report on such information should be restricted in light of
the limited nature of the review procedures applied. Deloitte & Touche LLP are
not subject to the liability provisions of Section 11 of the Securities Act for
their report on the unaudited interim financial information because those
reports are not 'reports' or a 'part' of the registration statement prepared or
certified by an accountant within the meaning of Sections 7 and 11 of the
Securities Act.
 
     The consolidated financial statements incorporated by reference in this
Prospectus Supplement from Norcen's Annual Report on Form 40-F for the years
ended December 31, 1997, and December 31, 1996, have been audited by Deloitte &
Touche, independent auditors as stated in their reports, which are incorporated
in the Norcen 8-K by reference. Such consolidated financial statements have been
incorporated by reference in this Prospectus Supplement in reliance upon the
reports of such firm given upon their authority as experts in accounting and
auditing.
 
     With respect to the unaudited interim financial information for the quarter
ended March 31, 1998, Arthur Andersen LLP has applied limited procedures in
accordance with professional standards for a review of that information.
However, their separate report thereon states that they did not audit and they
do not express an opinion on that interim financial information. Accordingly,
the degree of reliance on their report on that information should be restricted
in light of the limited nature of the review procedures applied. In addition,
the accountants are not subject to the liability provisions of Section 11 of the
Securities Act for their report on the unaudited interim financial information
because that report is not a 'report' or a 'part' of this Prospectus Supplement
prepared or certified by the accountants within the meaning of Sections 7 and 11
of the Securities Act.

Debt Securities, the 'Debt Securities'), (iii) warrants to purchase Senior Debt
Securities (the 'Debt Warrants'), (iv) shares of preferred stock, without par
value, of the Company (the 'Preferred Stock'), (v) warrants to purchase shares
of Preferred Stock (the 'Preferred Stock Warrants'), (vi) shares of common
stock, without par value, of the Company (the 'Common Stock'), and (vii)
warrants to purchase shares of Common Stock (the 'Common Stock Warrants'), in
amounts, at prices and on terms to be determined by market conditions at the
time of offering. The Debt Warrants, Preferred Stock Warrants and Common Stock
Warrants are referred to herein collectively as the 'Warrants', and the Debt
Securities, Preferred Stock, Common Stock and the Warrants are referred to
herein collectively as the 'Company Securities'.
 
    UPRG Capital Trust I, UPRG Capital Trust II and UPRG Capital Trust III
(each, a 'UPRG Trust' and collectively, the 'UPRG Trusts'), each a statutory
business trust formed under Delaware law, may offer, from time to time,
preferred securities (the 'Trust Preferred Securities') with the payment of
dividends and payments on liquidation or redemption of the Trust Preferred
Securities issued by each such UPRG Trust guaranteed on a subordinated basis by
the Company to the extent described herein and in an accompanying prospectus
supplement (the 'Trust Guarantees'). The Company will be the owner of the trust
interests represented by common securities (the 'Trust Common Securities') to be
issued by each UPRG Trust. Unless indicated otherwise in a prospectus
supplement, each UPRG Trust exists for the sole purpose of issuing its trust
interests and investing the proceeds thereof in Subordinated Debt Securities.
The Company Securities and the Trust Preferred Securities are referred to herein
collectively as the 'Offered Securities'.
 
    The Offered Securities may be issued in one or more series or issuances and
will be limited to $900,000,000 in aggregate public offering price (or its
equivalent, based on the applicable exchange rate, to the extent Debt Securities
are issued for one or more foreign currencies or currency units). The Offered
Securities may be sold for U.S. dollars, or any foreign currency or currencies
or currency units, and the principal of, any premium on, and any interest on,
the Debt Securities may be payable in U.S. dollars, or any foreign currency or
currencies or currency units.
 
    The Offered Securities may be offered separately or as units with other
Offered Securities, in separate series in amounts, at prices and on terms to be
determined at or prior to the time of sale. The sale of other securities under
the Registration Statement of which this Prospectus forms a part or under a
Registration Statement to which this Prospectus relates will reduce the amount
of Offered Securities which may be sold hereunder.
 
    The specific terms of the Offered Securities in respect of which this
Prospectus is being delivered are set forth in the accompanying Prospectus
Supplement (the 'Prospectus Supplement'), including, where applicable, (i) in

the case of Debt Securities, the specific designation, aggregate principal
amount, authorized denomination, initial offering price, maturity (which may be
fixed or extendible), premium (if any), interest rate (which may be fixed or
floating), time of and method of calculating the payment of interest, if any,
the currency in which principal, premium, if any, and interest, if any, are
payable, any redemption or sinking fund terms and other specific terms; (ii) in
the case of Preferred Stock or Trust Preferred Securities, the designation,
number of shares, liquidation preference per share, initial public offering
price, dividend rate (or method of calculation thereof), dates on which
dividends shall be payable and dates from which dividends shall accrue, any
redemption or sinking fund provisions and any conversion or exchange provisions;
(iii) in the case of Common Stock, the number of shares and the terms of the
offering and sale thereof; (iv) in the case of Warrants, the number and terms
thereof, the designation, description and the number of securities issuable upon
exercise, the exercise price, the terms of the offering and sale thereof and
where applicable, the duration and detachability thereof; and (v) in the case of
all Offered Securities, whether such Offered Securities will be offered
separately or as a unit with other Offered Securities. The Prospectus Supplement
will also contain information, where applicable, about certain United States
Federal income tax considerations relating to, and any listing on a securities
exchange of, the Offered Securities covered by the Prospectus Supplement.

which this Prospectus is being delivered, the names of such agents, dealers or
underwriters and any applicable agent's commission, dealer's purchase price or
underwriter's discount will be set forth in or may be calculated from the

such sale will be the purchase price less such commission in the case of an
agent, the purchase price in the case of a dealer, or the public offering price
less such discount in the case of an underwriter and less, in each case, other
attributable issuance expenses. See 'Plan of Distribution'.

                             AVAILABLE INFORMATION
 
     The Company is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the 'Exchange Act'), and in accordance
therewith files reports and other information with the Securities and Exchange
Commission (the 'Commission') relating to its business, financial position,
results of operations and other matters. Such reports and other information can

be inspected and copied at the Public Reference Section maintained by the
Commission at Judiciary Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549
and at certain of its Regional Offices, located at Northwest Atrium Center
(Suite 1400), 500 West Madison Street, Chicago, Illinois 60661, and Seven World
Trade Center, 13th Floor, New York, New York 10048. Copies of such material can
also be obtained from the Public Reference Section of the Commission at
prescribed rates. Such material can also be inspected at the offices of the New
York Stock Exchange, 20 Broad Street, New York, New York 10005. Such material
may also be accessed electronically by means of the Commission's home page on
the Internet (http://www.sec.gov).
 
     No separate financial statements of the UPRG Trusts have been included or
incorporated by reference herein. Neither the UPRG Trusts nor the Company
considers such financial statements material to holders of Trust Preferred
Securities because (i) all of the voting securities of each UPRG Trust will be
owned, directly or indirectly, by the Company, a reporting company under the
Exchange Act, (ii) no UPRG Trust has independent operations but rather each
exists for the purpose of issuing securities representing undivided beneficial
interests in the assets of such UPRG Trust and investing the proceeds thereof in
Subordinated Debt Securities, and (iii) the obligations of the UPRG Trusts under
the Trust Preferred Securities are fully and unconditionally guaranteed on a
subordinated basis by the Company to the extent set forth herein. See 'The UPRG
Trusts' and 'Description of Trust Preferred Securities and Trust
Guarantees--Trust Guarantees.'
 
     The Company and the UPRG Trusts have filed with the Commission a joint
registration statement (the 'Registration Statement') under the Securities Act
of 1933, as amended (the 'Securities Act'), with respect to the securities
offered hereby. This Prospectus does not contain all the information set forth
in the Registration Statement, certain parts of which are omitted in accordance
with the rules and regulations of the Commission. Reference is made to the
Registration Statement and to the exhibits relating thereto for further
information with respect to the Company, the UPRG Trusts and the securities
offered hereby.

is contained in the Registration Statement filed under the Exchange Act under
File No. 1-13916, including all amendments or reports filed for the purpose of

15(d) of the Exchange Act after the date of this Prospectus and before the
termination of the offering of the Offered Securities offered hereby shall be
deemed incorporated herein by reference, and such documents shall be deemed to
be a part hereof from the date of filing such documents. Any statement contained
herein, in a document incorporated or deemed to be incorporated by reference
herein, or in the accompanying Prospectus Supplement, shall be deemed to be

                                  THE COMPANY
 
     The Company is one of the largest independent energy companies in North
America and is engaged primarily in the exploration for and the development and
production of natural gas, natural gas liquids and crude oil in several major
producing basins in the United States and Canada. The Company emphasizes natural
gas in its exploration and production activities and also owns and operates
significant assets, in proximity to its principal producing properties,
dedicated to 'gas value chain' activities, which consist of the gathering,
processing, transportation and marketing of natural gas and natural gas liquids.
The Company, through its wholly owned subsidiary, Union Pacific Fuels, Inc. ('UP
Fuels'), markets a substantial portion of the Company's natural gas and
substantially all of its natural gas liquids and its crude oil, together with
significant volumes of natural gas, natural gas liquids and crude oil produced
by others. UP Fuels ranks among the largest natural gas and natural gas liquids
marketers in the United States. In addition, the Company engages in the hard
minerals business through non-operated joint venture and royalty interests in
several coal and trona (natural soda ash) mines.
 
     The Company's oil and gas activities are concentrated in six core
geographic areas: (1) the Austin Chalk trend in Texas and Louisiana, (2) the
Rockies, consisting of the western portion of the Land Grant Area (as defined
below) in Wyoming and Utah, (3) Plains/Canada, consisting of the eastern portion
of the Land Grant Area in Wyoming and Colorado, with additional operations in
Kansas and western Canada, (4) the onshore and offshore Gulf Coast area, (5)
eastern and southern Texas and (6) western Texas. In each of these core areas,
the focus of the Company is on the exploration for and development of natural
gas and crude oil resources, and on efforts to increase margins through
reductions in drilling and operating costs and effective and efficient sales and
distribution networks. The Company's hard minerals activities are conducted in
areas within and adjacent to the Land Grant Area. The 'Land Grant Area' consists
of land granted by the Federal government to a predecessor of Union Pacific
Corporation ('UPC') in the mid-1800s and significant additional acreage in the
same geographic region. The Land Grant Area passes through the states of
Colorado and Wyoming and into Utah and intersects several highly productive oil
and gas basins. In the Land Grant Area, the Company has fee ownership of the

mineral rights under approximately 7.5 million acres and control of mineral
rights under approximately 700,000 additional acres.
 
     In October 1995, 42.5 million shares (representing approximately 17%) of
the common stock of the Company were sold in an initial public offering. At such
time, the remaining 83% of the Company's common stock was owned by UPC. In
October 1996, UPC distributed pro rata to its stockholders as a dividend its
remaining shares of common stock of the Company by means of a tax free
distribution.

accounting changes less equity in undistributed earnings of unconsolidated
affiliates, plus income taxes and fixed charges. Fixed charges represent
interest, amortization of debt discount and expense, and the estimated interest
portion of rental charges.
 
                                THE UPRG TRUSTS
 
     Each of UPRG Capital Trust I, UPRG Capital Trust II and UPRG Capital Trust
III is a statutory business trust formed under Delaware law pursuant to (i) a
separate Declaration of Trust (a 'Declaration') executed by the Company, as
sponsor for such UPRG Trust, and the Trustees (as defined herein) of such trust
and (ii) the filing of a certificate of trust with the Delaware Secretary of
State. Unless an accompanying Prospectus Supplement provides otherwise, each
UPRG Trust exists for the sole purposes of (i) issuing the Trust Preferred
Securities, (ii) investing the gross proceeds of the sale of the Trust Preferred
Securities in a specific series of
 
                                       3
<PAGE>
Subordinated Debt Securities and (iii) engaging in only those other activities
necessary or incidental thereto. All of the Trust Common Securities will be
owned by the Company. The Trust Common Securities will rank pari passu, and
payments will be made thereon pro rata, with the Trust Preferred Securities,
except that upon the occurrence and continuance of an event of default under the
applicable Declaration, the rights of the holders of the applicable Trust Common

Securities to payment in respect of distributions and payments upon liquidation,
redemption and otherwise will be subordinated to the rights of the holders of
the applicable Trust Preferred Securities. The Company will acquire Trust Common
Securities having an aggregate liquidation amount equal to a minimum of 1% of
the total capital of each UPRG Trust. Each UPRG Trust will have a term of at
least 20 but not more than 50 years, but may terminate earlier as provided in
the applicable Declaration. Each UPRG Trust's business and affairs will be
conducted by the Trustees. The holder of the Trust Common Securities will be
entitled to appoint, remove or replace any of, or increase or reduce the number
of, the Trustees of each UPRG Trust. The duties and obligations of the Trustees
shall be governed by the Declaration of such UPRG Trust. At least one of the
Trustees of each UPRG Trust will be a person who is an employee or officer of or
who is affiliated with the Company (a 'Regular Trustee'). One Trustee of UPRG
Trust will be a financial institution that is not affiliated with the Company,
which shall act as property trustee and as indenture trustee for the purposes of
the Trust Indenture Act of 1939, as amended (the 'Trust Indenture Act'),
pursuant to the terms set forth in a Prospectus Supplement (the 'Property
Trustee'). In addition, unless the Property Trustee maintains a principal place
of business in the State of Delaware and otherwise meets the requirements of
applicable law, one Trustee of each UPRG Trust will be a legal entity having a
principal place of business in, or an individual resident of, the State of
Delaware (the 'Delaware Trustee'). The Company will pay all fees and expenses
related to each UPRG Trust and the offering of the Trust Preferred Securities.
Unless otherwise set forth in the Prospectus Supplement, the Property Trustee
will be Texas Commerce Bank National Association ('TCB'), and the Delaware
Trustee will be The Chase Manhattan Bank, Delaware. The office of the Delaware
Trustee in the State of Delaware is 1201 Market Street, Wilmington, Delaware
19801. The principal place of business of each UPRG Trust is c/o Union Pacific
Resources Group Inc., 801 Cherry Street, Fort Worth, Texas 76102. Telephone:
(817) 877-6000.
 
                                USE OF PROCEEDS
 
     Unless otherwise specified in the Prospectus Supplement, the net proceeds
from the sale of the Company Securities offered hereby will be used for general
corporate purposes, including repayment of borrowings, working capital, capital
expenditures, stock repurchase programs and acquisitions. Unless otherwise
specified in the Prospectus Supplement, each UPRG Trust will use all proceeds
received from the sale of Trust Preferred Securities to purchase Subordinated
Debt Securities of the Company. Additional information on the use of net
proceeds from the sale of the Offered Securities offered hereby may be set forth
in the Prospectus Supplement relating to such Offered Securities.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The following description of the terms of the Debt Securities summarizes
certain general terms and provisions of the Debt Securities to which any
Prospectus Supplement may relate. The particular terms of the Senior Debt
Securities, any Subordinated Debt Securities issued in connection with Trust
Preferred Securities, and the extent, if any, to which such general provisions
may apply to any series of Debt Securities will be described in the Prospectus
Supplement relating to such series.
 
     Senior Debt Securities may be issued, from time to time, in one or more

series under an Indenture (the 'Senior Indenture'), between the Company and TCB,
as trustee, or such other trustee as shall be named in a Prospectus Supplement
(the 'Senior Trustee'). The Senior Indenture is filed as an exhibit to the
Registration Statement of which this Prospectus is a part. Subordinated Debt
Securities may be issued, from time to time, in one or more series under an
indenture (the 'Subordinated Indenture') between the Company and a trustee to be
identified in the related Prospectus Supplement (the 'Subordinated Trustee').
The Subordinated Indenture will be filed with the Commission and incorporated by
reference as an exhibit to the Registration Statement of which this Prospectus
is a part. The Senior Indenture and the Subordinated Indenture are sometimes
referred to collectively as the 'Indentures,' and the Senior Trustee and the
Subordinated Trustee are sometimes referred to collectively as the 'Debt
Trustees.' The following statements are subject to the detailed provisions of
the
 
                                       4
<PAGE>
Indentures. Wherever any particular provisions of the Indentures or terms
defined therein are referred to, such provisions and terms are incorporated by
reference as a part of the statements made herein and such statements are
qualified in their entirety by such references, including the definitions
therein of certain terms. References to particular sections of the Indentures
are noted below. Capitalized terms used herein but not defined herein shall have
the meanings ascribed to them in the Indentures.
 
GENERAL
 
     The Senior Debt Securities will be unsecured and will rank equally and
ratably with other unsecured and unsubordinated debt of the Company, unless the
Company shall be required to secure the Senior Debt Securities as described
below under 'Covenants--Limitation on Liens and Sale Leaseback Transactions.'
The Senior Indenture does not limit the amount of Senior Debt Securities that
can be issued thereunder. (Section 301) Senior Debt Securities will be issued
from time to time and offered on terms determined by market conditions at the
time of sale.
 
     The obligations of the Company pursuant to any Subordinated Debt Securities
will be subordinate in right of payment to all Senior Indebtedness of the
Company, and will be described in an accompanying Prospectus Supplement. The
Subordinated Indenture will not contain any limitation on the amount of Senior
Indebtedness which may be hereafter incurred by the Company.
 
     The Debt Securities may be issued in one or more series with the same or
various maturities, at par, at a premium or at a discount. Any Debt Securities
bearing no interest or interest at a rate which at the time of issuance is below
market rates will be sold at a discount (which may be substantial) from their
stated principal amount. Federal income tax consequences and other special
considerations applicable to any such substantially discounted Debt Securities
will be described in the Prospectus Supplement relating thereto.
 
     Reference is made to the Prospectus Supplement for the following terms of
the Debt Securities offered hereby: (i) the designation, aggregate principal
amount and authorized denominations of such Debt Securities; (ii) the percentage
of their principal amount at which such Debt Securities will be issued; (iii)

the date or dates on which the Debt Securities will mature (which may be fixed
or extendible); (iv) the rate or rates (which may be fixed or floating) per
annum at which the Debt Securities will bear interest, if any, or the method of
determining such rate or rates; (v) the date or dates on which any such interest
will be payable, the date or dates on which payment of any such interest will
commence and the Regular Record Dates for such Interest Payment Dates; (vi) the
terms of any mandatory or optional redemption (including any provisions for any
sinking, purchase or other analogous fund) or repayment option; (vii) the
currency, currencies or currency units for which the Debt Securities may be
purchased and the currency, currencies or currency units in which the principal
thereof, any premium thereon and any interest thereon may be payable; (viii) if
the currency, currencies or currency units for which the Debt Securities may be
purchased or in which the principal thereof, any premium thereon and any
interest thereon may be payable is at the election of the Company or the
purchaser, the manner in which such election may be made; (ix) if the amount of
payments on the Debt Securities is determined with reference to an index based
on one or more currencies or currency units, changes in the price of one or more
securities or changes in the price of one or more commodities, the manner in
which such amounts may be determined; (x) the extent to which any of the Debt
Securities will be issuable in temporary or permanent global form, or the manner
in which any interest payable on a temporary or permanent Global Security will
be paid; (xi) the terms and conditions upon which conversion or exchange of the
Debt Securities into other Debt Securities will be effected, including the
conversion price or exchange ratio, the conversion or exchange period and any
other conversion or exchange provisions; (xii) information with respect to
book-entry procedures, if any; (xiii) a discussion of certain Federal income
tax, accounting and other special considerations, procedures and limitations
with respect to the Debt Securities; and (xiv) any other specific terms of the
Debt Securities not inconsistent with the Indenture. In addition, the applicable
Prospectus Supplement will describe the following terms of the series of
Subordinated Debt Securities offered hereby in respect of which this Prospectus
is being delivered: (a) the rights, if any, to defer payments of interest on the
Subordinated Debt Securities by extending the interest payment period, and the
duration of such extensions, and (b) the subordination terms of the Subordinated
Debt Securities of such series.
 
     If any of the Debt Securities are sold for one or more foreign currencies
or foreign currency units or if the principal of, premium, if any, or any
interest on any series of Debt Securities is payable in one or more foreign
currencies or foreign currency units, the restrictions, elections, Federal
income tax consequences, specific terms
 
                                       5
<PAGE>
and other information with respect to such issue of Debt Securities and such
currencies or currency units will be set forth in the Prospectus Supplement
relating thereto.
 
     Unless otherwise specified in the Prospectus Supplement, the principal of,
any premium on, and any interest on the Debt Securities will be payable, and the
Debt Securities will be transferable, at the Corporate Trust Office of the
applicable Debt Trustee in New York, New York, provided that payment of
interest, if any, may be made at the option of the Company by check mailed on or
before the payment date, first class mail, to the address of the person entitled

thereto as it appears on the registry books of the Company or its agent.
 
     Unless otherwise specified in the Prospectus Supplement, the Senior Debt
Securities will be issued only in fully registered form and in denominations of
$1,000 and any integral multiple thereof (Sections 301 and 302) and Subordinated
Debt Securities issued in connection with the Trust Preferred Securities will be
issued in denominations of $25 or integral multiples thereof. No service charge
will be made for any transfer or exchange of any Debt Securities, but the
Company may, except in certain specified cases not involving any transfer,
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. (Section 305)
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on behalf
of, a depositary (the 'Depositary') identified in the Prospectus Supplement
relating to such series. Global Securities may be issued only in fully
registered form and in either temporary or permanent form. Unless and until it
is exchanged in whole or in part for the individual Debt Securities represented
thereby, a Global Security may not be transferred except as a whole by the
Depositary for such Global Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by the Depositary or any nominee of such Depositary to a successor
Depositary or any nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Debt Securities will be described in the Prospectus Supplement relating to
such series. The Company anticipates that the following provisions will
generally apply to depositary arrangements.
 
     Upon the issuance of a Global Security, the Depositary for such Global
Security or its nominee will credit, on its book entry registration and transfer
system, the respective principal amounts of the individual Debt Securities
represented by such Global Security to the accounts of persons that have
accounts with such Depositary. Such accounts shall be designated by the dealers,
underwriters or agents with respect to such Debt Securities or by the Company if
such Debt Securities are offered and sold directly by the Company. Ownership of
beneficial interests in a Global Security will be limited to persons that have
accounts with the applicable Depositary ('participants') or persons that may
hold interests through participants. Ownership of beneficial interests in such
Global Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the applicable Depositary or its
nominee (with respect to interests of participants) and the records of
participants (with respect to interests of persons other than participants). The
laws of some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Security.
 
     So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
applicable Indenture. Except as provided below, owners of beneficial interests

in a Global Security will not be entitled to have any of the individual Debt
Securities of the series represented by such Global Security registered in their
names, will not receive or be entitled to receive physical delivery of any such
Debt Securities of such series in definitive form and will not be considered the
owners or holders thereof under the applicable Indenture governing such Debt
Securities.
 
     Payments of principal of, any premium on, and any interest on, individual
Debt Securities represented by a Global Security registered in the name of a
Depositary or its nominee will be made to the Depositary or its nominee, as the
case may be, as the registered owner of the Global Security representing such
Debt Securities. Neither the Company, the applicable Debt Trustee for such Debt
Securities, any Paying Agent, nor the Security Registrar for such Debt
Securities will have any responsibility or liability for any aspect of the
records relating to
 
                                       6
<PAGE>
or payments made on account of beneficial ownership interests of the Global
Security for such Debt Securities or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.
 
     The Company expects that the Depositary for a series of Debt Securities or
its nominee, upon receipt of any payment of principal, premium or interest in
respect of a permanent Global Security representing any of such Debt Securities,
immediately will credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such Global Security for such Debt Securities as shown on the records of such
Depositary or its nominee. The Company also expects that payments by
participants to owners of beneficial interests in such Global Security held
through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in 'street name'. Such payments will be
the responsibility of such participants.
 
     If the Depositary for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as depositary and a successor depositary is not
appointed by the Company within 90 days, the Company will issue individual Debt
Securities of such series in exchange for the Global Security representing such
series of Debt Securities. In addition, the Company may at any time and in its
sole discretion, subject to any limitations described in the Prospectus
Supplement relating to such Debt Securities, determine not to have any Debt
Securities of a series represented by one or more Global Securities and, in such
event, will issue individual Debt Securities of such series in exchange for the
Global Security or Securities representing such series of Debt Securities.
Further, if the Company so specifies with respect to the Debt Securities of a
series, an owner of a beneficial interest in a Global Security representing Debt
Securities of such series may, on terms acceptable to the Company, the
applicable Debt Trustee and the Depositary for such Global Security, receive
individual Debt Securities of such series in exchange for such beneficial
interests, subject to any limitations described in the Prospectus Supplement
relating to such Debt Securities. In any such instance, an owner of a beneficial
interest in a Global Security will be entitled to physical delivery of
individual Debt Securities of the series represented by such Global Security

equal in principal amount to such beneficial interest and to have such Debt
Securities registered in its name. Individual Debt Securities of such series so
issued will be issued in denominations, unless otherwise specified by the
Company, of $1,000 and integral multiples thereof, in the case of Senior Debt
Securities, and $25 and integral multiples thereof, in the case of Subordinated
Debt Securities.

applicable (unless waived or amended) so long as any of the Senior Debt
Securities are outstanding, unless stated otherwise in the Prospectus
Supplement.
 
     Limitation on Liens and Sale Leaseback Transactions.  (a) The Company will
not, nor will it permit any Subsidiary to, create, assume, incur or suffer to
exist any Mortgage upon any stock or indebtedness of any Domestic Subsidiary,
whether owned on the date of the Senior Indenture or thereafter acquired, to
secure any Debt of the Company or any other person (other than the Senior Debt
Securities), without in any such case making effective provision whereby all the
outstanding Senior Debt Securities shall be directly secured equally and ratably
with such Debt. There will be excluded from this restriction any Mortgage upon
stock or indebtedness of a corporation existing at the time such corporation
becomes a Domestic Subsidiary or at the time stock or indebtedness of a Domestic
Subsidiary is acquired and any extension, renewal or replacement of any such
Mortgage.
 
     (b) The Company will not, nor will it permit any Restricted Subsidiary to,
create, assume, incur or suffer to exist any Mortgage upon any Principal
Property, whether owned or leased on the date of the Senior Indenture, or
thereafter acquired, to secure any Debt of the Company or any other person
(other than the Senior Debt Securities), without in any such case making
effective provision whereby all the outstanding Senior Debt Securities shall be
directly secured equally and ratably with such Debt. (Section 1006)
 
     There will be excluded from the restriction referred to in the next
preceding paragraph the following Mortgages (the Mortgages set forth in the
following clauses (i) through (vi) the 'Permitted Mortgages') (i) any Mortgage
upon property owned or leased by a corporation existing at the time such
corporation becomes a Restricted Subsidiary, (ii) any Mortgage upon property

Mortgage securing Debt of a Restricted Subsidiary owing to the Company or to
another Restricted Subsidiary, (v) any Mortgage existing on the date of the
Senior Indenture, and (vi) any extension, renewal or replacement, in whole or in

exceed the principal amount of Debt so secured at the time of such extension,
renewal or replacement; and provided, further, that such Mortgage shall be
limited to all or such part of the property which secured the Mortgage so
extended, renewed or replaced.
 
     Notwithstanding the foregoing, the Company may, and may permit any
Restricted Subsidiary to, create, assume, incur or suffer to exist any Mortgage
upon any Principal Property without equally and ratably securing the Senior Debt
Securities if the aggregate amount of all Debt then outstanding secured by such
Mortgage and all similar Mortgages does not exceed 10% of the total consolidated
stockholders' equity (including preferred stock) of the Company as shown on the
audited consolidated balance sheet contained in the latest annual report to
stockholders of the Company; provided that Debt secured by Permitted Mortgages
shall not be included in the amount of such secured Debt.

     For the purpose of the restriction referred to in the third preceding
paragraph, no Mortgage to secure any Debt will be deemed created by (i) the sale

time until, or in an amount such that, the purchaser will realize therefrom a
specified amount of money (however determined) or a specified amount of such oil
or gas or minerals, or (B) any other interest commonly referred to as a
'production payment', and (ii) any Mortgage in favor of the United States (or
any State thereof), or any other country, or any political subdivision of any of
the foregoing, to secure partial, progress, advance or other payments pursuant
to any contract or statute, or any Mortgage upon property intended to be used
primarily for the purpose of or in connection with air or water pollution
control. (Section 1006)
 
     (c) The Company will not, nor will it permit any Restricted Subsidiary to,
enter into any arrangement with any person providing for the leasing by the
Company or a Restricted Subsidiary as lessee of any Principal Property (except
for temporary leases for a term, including renewals, of not more than five
years), which property has been or is to be sold or transferred by the Company
or such Restricted Subsidiary to such person (herein referred to as a
'Sale-Leaseback Transaction'), unless (i) such Sale-Leaseback Transaction occurs
within 120 days from the date of acquisition of such Principal Property or the
date of the completion of construction or commencement of full operations on
such Principal Property, whichever is later, or (ii) the Company, within 120
days after such Sale-Leaseback Transaction, applies or causes to be applied to
the retirement of Funded Debt of the Company or any Subsidiary (other than
Funded Debt of the Company which by its terms or the terms of the instrument
pursuant to which it was issued is subordinate in right of payment to the Senior
Debt Securities) an amount not less than the net proceeds of the sale of such
Principal Property. (Section 1006)
 
     Notwithstanding the foregoing provisions of this paragraph (c), the Company

may, and may permit any Restricted Subsidiary to, effect any Sale-Leaseback
Transaction involving any Principal Property, provided that the net sale
proceeds from such Sale-Leaseback Transaction, together with all Debt secured by
Mortgages other than Permitted Mortgages, does not exceed 10% of the total
consolidated stockholders' equity of the Company as shown on the audited
consolidated balance sheet contained in the latest annual report to stockholders
of the Company.
 
     Limitation on Transfers of Principal Properties to Unrestricted
Subsidiaries.  The Company will not, nor will it permit any Restricted
Subsidiary to, sell, transfer or otherwise dispose of any Principal Property to
any Subsidiary which is not a Restricted Subsidiary other than for cash or other
consideration which, in the opinion of the Company's Board of Directors,
constitutes fair value for such Principal Property. (Section 1007)
 
CONSOLIDATION, MERGER, SALE OR CONVEYANCE
 
     Each Indenture provides that the Company may not consolidate with or merge
into any other corporation or convey or transfer its properties and assets
substantially as an entirety to any person, unless (i) the successor corporation
shall be a corporation organized and existing under the laws of the United
States or any State thereof or the District of Columbia, and shall expressly
assume by a supplemental indenture the due and punctual payment of the principal
of, any premium on, and any interest on, all the outstanding Debt Securities and
the performance of every covenant in the applicable Indenture on the part of the
Company to be performed or observed; (ii) immediately after giving effect to
such transaction, no Event of Default, and no event which, after notice or lapse
of time or both, would become an Event of Default, shall have happened and be
continuing; and (iii) the Company shall have delivered to the applicable Debt
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
such consolidation, merger, conveyance or transfer and such supplemental
indenture comply with the foregoing provisions relating to such transaction.
(Section 801) In case of any such consolidation, merger, conveyance or transfer,
such successor corporation will succeed to and be substituted for the Company as
obligor on the Debt Securities, with the same effect as if it had been named in
the applicable Indenture as the Company. (Section 802) Other than the
restrictions on Mortgages described above, the Indentures and the Debt
Securities do not contain any covenants or other provisions designed to protect
holders of Debt Securities in the event of a highly leveraged transaction
involving the Company or any Subsidiary.
 
EVENTS OF DEFAULT; WAIVER AND NOTICE THEREOF; DEBT SECURITIES IN FOREIGN
CURRENCIES
 
     As to any series of Debt Securities, an Event of Default is defined in each
Indenture as (a) default for 30 days in payment of any interest on the Debt
Securities of such series; (b) default in payment of principal of or any premium
on the Debt Securities of such series at maturity; (c) default in payment of any
sinking or purchase fund or analogous obligation, if any, on the Debt Securities
of such series; (d) default by the Company in the
 
                                       9
<PAGE>
performance of any other covenant or warranty contained in the applicable

Indenture for the benefit of such series which shall not have been remedied for
a period of 90 days after notice is given as specified in the applicable
Indenture; and (e) certain events of bankruptcy, insolvency and reorganization
of the Company. (Section 501)
 
     A default under other indebtedness of the Company will not be a default
under the Indentures and a default under one series of Debt Securities will not
necessarily be a default under another series.
 
     Each Indenture provides that (i) if an Event of Default described in clause
(a), (b), (c) or (d) above (if the Event of Default under clause (d) is with
respect to less than all series of Debt Securities then outstanding) shall have
occurred and be continuing with respect to any series, either the applicable
Debt Trustee or the holders of not less than 25% in aggregate principal amount
of the Debt Securities of such series then outstanding (each such series acting
as a separate class) may declare the principal (or, in the case of Original
Issue Discount Securities, the portion thereof specified in the terms thereof)
of all outstanding Debt Securities of such series and the interest accrued
thereon, if any, to be due and payable immediately and (ii) if an Event of
Default described in clause (d) or (e) above (if the Event of Default under
clause (d) is with respect to all series of Debt Securities then outstanding)
shall have occurred and be continuing, either the applicable Debt Trustee or the
holders of at least 25% in aggregate principal amount of all Debt Securities
then outstanding (treated as one class) may declare the principal (or, in the
case of Original Issue Discount Securities, the portion thereof specified in the
terms thereof) of all Debt Securities then outstanding and the interest accrued
thereon, if any, to be due and payable immediately, but upon certain conditions
such declarations may be annulled and past defaults (except for defaults in the
payment of principal of, any premium on, or any interest on, such Debt
Securities and in compliance with certain covenants) may be waived by the
holders of a majority in aggregate principal amount of the Debt Securities of
such series then outstanding. (Sections 502 and 513)
 
     Under each Indenture the applicable Debt Trustee must give to the holders
of each series of Debt Securities notice of all uncured defaults known to it
with respect to such series within 90 days after such a default occurs (the term
'default' to include the events specified above without notice or grace
periods); provided that, except in the case of default in the payment of
principal of, any premium on, or any interest on, any of the Debt Securities, or
default in the payment of any sinking or purchase fund installment or analogous
obligations, the applicable Debt Trustee shall be protected in withholding such
notice if it in good faith determines that the withholding of such notice is in
the interests of the holders of the Debt Securities of such series. (Section
602)
 
     No holder of any Debt Securities of any series may institute any action
under either Indenture unless (a) such holder shall have given the Debt Trustee
thereunder written notice of a continuing Event of Default with respect to such
series, (b) the holders of not less than 25% in aggregate principal amount of
the Debt Securities of such series then outstanding shall have requested the
Debt Trustee thereunder to institute proceedings in respect of such Event of
Default, (c) such holder or holders shall have offered the Debt Trustee
thereunder such reasonable indemnity as such Debt Trustee may require, (d) the
Debt Trustee thereunder shall have failed to institute an action for 60 days

thereafter and (e) no inconsistent direction shall have been given to the Debt
Trustee thereunder during such 60-day period by the holders of a majority in
aggregate principal amount of Debt Securities of such series. (Section 507)
 
     The holders of a majority in aggregate principal amount of the Debt
Securities of any series affected and then outstanding will have the right,
subject to certain limitations, to direct the time, method and place of
conducting any proceeding for any remedy available to the applicable Debt
Trustee or exercising any trust or power conferred on such Debt Trustee with
respect to such series of Debt Securities. (Section 512) Each Indenture provides
that, in case an Event of Default shall occur and be continuing, the Debt
Trustee thereunder, in exercising its rights and powers under such Indenture,
will be required to use the degree of care of a prudent man in the conduct of
his own affairs. (Section 601) Each Indenture further provides that the Debt
Trustee thereunder shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
under such Indenture unless it has reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
reasonably assured to it. (Section 601)
 
     The Company must furnish to the Debt Trustees within 120 days after the end
of each fiscal year a statement signed by one of certain officers of the Company
to the effect that a review of the activities of the Company during such year
and of its performance under the applicable Indenture and the terms of the Debt
Securities has been made, and, to the best of the knowledge of the signatories
based on such review, the Company has complied
 
                                       10
<PAGE>
with all conditions and covenants of such Indenture or, if the Company is in
default, specifying such default. (Section 1004)
 
     If any Debt Securities are denominated in a coin or currency other than
that of the United States, then for the purposes of determining whether the
holders of the requisite principal amount of Debt Securities have taken any
action as herein described, the principal amount of such Debt Securities shall
be deemed to be that amount of United States dollars that could be obtained for
such principal amount on the basis of the spot rate of exchange into United
States dollars for the currency in which such Debt Securities are denominated
(as evidenced to the applicable Debt Trustee by an Officers' Certificate) as of
the date the taking of such action by the holders of such requisite principal
amount is evidenced to the applicable Debt Trustee as provided in the respective
Indenture. (Section 104)
 
     If any Debt Securities are Original Issue Discount Securities, then for the
purposes of determining whether the holders of the requisite principal amount of
Debt Securities have taken any action herein described, the principal amount of
such Debt Securities shall be deemed to be the portion of such principal amount
that would be due and payable at the time of the taking of such action upon a
declaration of acceleration of maturity thereof. (Section 101)
 
MODIFICATION OF THE INDENTURES
 
     With certain exceptions, the applicable Indenture or the rights of the

holders of the Debt Securities may be modified by the Company and the applicable
Debt Trustee with the consent of the holders of a majority in aggregate
principal amount of the Debt Securities of each series affected by such
modification then outstanding, but no such modification may be made without the
consent of the holder of each outstanding Debt Security affected thereby which
would (i) change the maturity of any payment of principal of, or any premium on,
or any installment of interest on any Debt Security, or reduce the principal
amount thereof or the interest or any premium thereon, or change the method of
computing the amount of principal thereof or interest thereon on any date or
change any place of payment where, or the coin or currency in which, any Debt
Security or any premium or interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the maturity
thereof (or, in the case of redemption or repayment, on or after the redemption
date or the repayment date, as the case may be), or (ii) reduce the percentage
in principal amount of the outstanding Debt Securities of any series, the
consent of whose holders is required for any such modification, or the consent
of whose holders is required for any waiver of compliance with certain
provisions of the applicable Indenture or certain defaults thereunder and their
consequences provided for in such Indenture, or (iii) modify any of the
provisions of certain Sections of the applicable Indenture, including the
provisions summarized in this paragraph, except to increase any such percentage
or to provide that certain other provisions of such Indenture cannot be modified
or waived without the consent of the holder of each outstanding Debt Security
affected thereby. (Section 902)
 
DEFEASANCE OF THE INDENTURE AND DEBT SECURITIES
 
     If the terms of any series of Debt Securities so provide, the Company will
be deemed to have paid and discharged the entire indebtedness on all the
outstanding Debt Securities of such series by (a) depositing with the applicable
Debt Trustee (i) as trust funds in trust an amount sufficient to pay and
discharge the entire indebtedness on all Debt Securities of such series for
principal, premium and interest or (ii) as obligations in trust such amount of
direct obligations of, or obligations the principal of and interest on which are
fully guaranteed by, the government which issued the currency in which the Debt
Securities are denominated as will, together with the income to accrue thereon
without consideration of any reinvestment thereof, be sufficient to pay and
discharge the entire indebtedness on all such Debt Securities for principal,
premium and interest and (b) satisfying certain other conditions precedent
specified in the applicable Indenture. (Section 403) In the event of any such
defeasance, holders of such Debt Securities would be able to look only to such
trust fund for payment of principal of, any premium on, and any interest on
their Debt Securities.
 
     Such defeasance is likely to be treated as a taxable exchange by holders of
the relevant Debt Securities for an issue consisting of either obligations of
the trust or a direct interest in the cash and securities held in the trust,
with the result that such holders would be required for tax purposes to
recognize gain or loss as if such obligations or the cash or securities
deposited, as the case may be, had actually been received by them in exchange
for their Debt Securities. In addition, if the holders are treated as the owners
of their proportionate share
 
                                       11

<PAGE>
of the cash or securities held in trust, such holders would then be required to
include in their income for tax purposes any income, gain or loss attributable
thereto even though no cash was actually received. Thus, such holders might be
required to recognize income for tax purposes in different amounts and at
different times than would be recognized in the absence of defeasance.
Prospective investors are urged to consult their own tax advisors as to the
specific consequences of defeasance.

Warrants.
 
         DESCRIPTION OF TRUST PREFERRED SECURITIES AND TRUST GUARANTEES
 
TRUST PREFERRED SECURITIES
 
     The Declaration pursuant to which each UPRG Trust is organized will be
replaced by an Amended and Restated Declaration of Trust (the 'Amended
Declaration') which will authorize the trustees (the 'Trustees') of such trust
to issue on behalf of such UPRG Trust one series of Trust Preferred Securities
and one series of Trust Common Securities (together, the 'Trust Securities').
The Trust Preferred Securities will be issued to the public pursuant to the
Registration Statement of which this Prospectus forms a part, and the Trust
Common Securities will be issued directly or indirectly to the Company.
 
     The Trust Preferred Securities will have such terms, including dividends,
redemption, voting, conversion, liquidation rights and such other preferred,
deferred or other special rights or such restrictions as shall be set forth in
the applicable Declaration or made part of such Declaration by the Trust
Indenture Act. Reference is made to the applicable Prospectus Supplement
relating to the Trust Preferred Securities of such UPRG Trust for specific
terms, including (i) the distinctive designation of Trust Preferred Securities,
(ii) the number of Trust Preferred Securities issued by such UPRG Trust, (iii)
the annual dividend rate (or method of determining such rate) for Trust
Preferred Securities issued by such UPRG Trust and the date or dates upon which
such dividends shall be payable, (iv) whether dividends on Trust Preferred
Securities issued by such UPRG Trust shall be cumulative, and, in the case of
Trust Preferred Securities having such cumulative dividend rights, the date or
dates or method of determining the date or dates from which dividends on Trust
Preferred Securities issued by such UPRG Trust shall be cumulative, (v) the
amount or amounts which shall be paid out of the assets of such UPRG Trust to

the
 
                                       14
<PAGE>
holder of Trust Preferred Securities of such UPRG Trust upon voluntary or
involuntary dissolution, winding-up or termination of such UPRG Trust, (vi) the
terms and conditions, if any, under which Trust Preferred Securities of such
UPRG Trust may be converted into shares of Capital Stock of the Company,
including the conversion price per share and the circumstances, if any, under
which any such conversion right shall expire, (vii) the terms and conditions, if
any, upon which the related series of the applicable Subordinated Debt
Securities may be distributed to holders of Trust Preferred Securities of such
UPRG Trust, (ix) the obligation, if any, of such UPRG Trust to purchase or
redeem Trust Preferred Securities issued by such UPRG Trust and the price or
prices at which, the period or periods within which and the terms and conditions
upon which Trust Preferred Securities issued by such UPRG Trust shall be
purchased or redeemed, in whole or in part, pursuant to such obligation, (x) the
voting rights, if any, of Trust Preferred Securities issued by such UPRG Trust
in addition to those required by law, including the number of votes per Trust
Preferred Security and any requirement for the approval by the holders of Trust
Preferred Securities, or of Trust Preferred Securities issued by such UPRG
Trust, as a condition to specified action or amendments to the Declaration of
such UPRG Trust, and (xi) any other relevant rights, preferences, privileges,
limitations or restrictions of Trust Preferred Securities issued by such UPRG
Trust consistent with the Declaration of such UPRG Trust or with applicable law.
Pursuant to each Declaration, the Property Trustee will own the Subordinated
Debt Securities purchased by the applicable UPRG Trust for the benefit of the
holders of the Trust Preferred Securities. The payment of dividends out of money
held by the UPRG Trusts, and payments upon redemption of Trust Preferred
Securities or liquidation of any UPRG Trust, will be guaranteed by the Company
to the extent described under '--Trust Guarantees.'
 
     Certain federal income tax considerations applicable to an investment in
Trust Preferred Securities will be described in the Prospectus Supplement
relating thereto.
 
     In connection with the issuance of Trust Preferred Securities, each UPRG
Trust will also issue one series of Trust Common Securities. Each Amended
Declaration will authorize the Regular Trustee of a UPRG Trust to issue on
behalf of such UPRG Trust one series of Trust Common Securities having such
terms, including dividends, conversion, redemption, voting, liquidation rights
or such restrictions as shall be set forth therein. Except as otherwise provided
in the Prospectus Supplement relating to the Trust Preferred Securities, the
terms of the Trust Common Securities issued by such UPRG Trust will be
substantially identical to the terms of the Trust Preferred Securities issued by
such UPRG Trust, and the Trust Common Securities will rank pari passu, and
payments will be made thereon pro rata with the Trust Preferred Securities
except that, upon an event of default under the applicable Declaration, the
rights of the holders of the Trust Common Securities to payment in respect of
dividends and payments upon liquidation, redemption and otherwise will be
subordinated to the rights of the holders of the Trust Preferred Securities.
Except in certain limited circumstances, the Trust Common Securities will also
carry the right to vote and appoint, remove or replace any of the Trustees of
the related UPRG Trust which issued such Trust Common Securities. All of the

Trust Common Securities of each UPRG Trust will be directly or indirectly owned
by the Company.
 
     The Property Trustee and its affiliates provide customary commercial
banking services to the Company and certain of its subsidiaries and participate
in various financing agreements of the Company in the ordinary course of their
business. The Property Trustee acts as the administrative agent under the
Revolving Credit Agreement dated as of October 5, 1995 among the Company and the
Property Trustee.
 
TRUST GUARANTEES
 
     Set forth below is a summary of information concerning the Trust Guarantees
which will be executed and delivered by the Company, from time to time, for the
benefit of the holders of Trust Preferred Securities. The accompanying
Prospectus Supplement will describe any significant differences between the
actual terms of the Trust Guarantees and the summary below. The following
summary does not purport to be complete and is subject in all respects to the
provisions of, and is qualified in its entirety by reference to, the Trust
Guarantee, which will be filed with the Commission and incorporated by reference
as an exhibit to the Registration Statement of which this Prospectus forms a
part.
 
     General.  The Company will irrevocably and unconditionally agree, to the
extent set forth in the Trust Guarantees, to pay in full, to the holders of
Trust Preferred Securities of each series, the Trust Guarantee Payments (as
defined below) (except to the extent paid by such UPRG Trust), as and when due,
regardless of any
 
                                       15
<PAGE>
defense, right of set-off or counterclaim which such UPRG Trust may have or
assert. The following payments with respect to any series of Trust Preferred
Securities to the extent not paid by the applicable UPRG Trust (the 'Trust
Guarantee Payments') will be subject to the Trust Guarantees (without
duplication): (i) any accrued and unpaid dividends which are required to be paid
on the Trust Preferred Securities of such series, to the extent such UPRG Trust
shall have funds legally available therefor, (ii) the redemption price,
including all accrued and unpaid dividends (the 'Redemption Price'), payable out
of funds legally available therefor, with respect to any Trust Preferred
Securities called for redemption by such UPRG Trust and (iii) upon a liquidation
of such UPRG Trust (other than in connection with the distribution of
Subordinated Debt Securities to the holders of Trust Preferred Securities or the
redemption of all of the Trust Preferred Securities issued by such UPRG Trust),
the lesser of (a) the aggregate of the liquidation preference and all accrued
and unpaid dividends on the Trust Preferred Securities of such series to the
date of payment and (b) the amount of assets of such UPRG Trust remaining
available for distribution to holders of Trust Preferred Securities of such
series in liquidation of such UPRG Trust. The Company's obligation to make a
Trust Guarantee Payment may be satisfied by direct payment of the required
amounts by the Company to the holders of Trust Preferred Securities or by
causing the applicable UPRG Trust to pay such amounts to such holders.
 
     Covenants of the Company.  In each Trust Guarantee, the Company will

covenant that, so long as any Trust Preferred Securities issued by the
applicable UPRG Trust remain outstanding, if there shall have occurred any event
that would constitute an event of default under such Trust Guarantee or the
Declaration of such UPRG Trust, then (a) the Company shall not declare or pay
any dividend on, make any distributions with respect to, or redeem, purchase or
make a liquidation payment with respect to, any of its Common Stock (other than
(i) purchases or acquisitions of shares of Common Stock in connection with the
satisfaction by the Company of its obligations under any employee benefit plan,
(ii) as a result of a reclassification of the Company's Common Stock or the
exchange or conversion of one class or series of the Company's Common Stock for
another class or series of the Company's Common Stock, (iii) the purchase of
fractional interests in shares of the Company's Common Stock pursuant to the
conversion or exchange provisions of such Common Stock of the Company or the
security being converted or exchanged or (iv) purchases or acquisitions of
shares of Common Stock to be used in connection with acquisitions of Common
Stock by shareholders pursuant to the Company's dividend reinvestment plan) or
make any guarantee payments with respect to the foregoing and (b) the Company
shall not make any payment of principal or premium, if any, on or repurchase any
debt securities (including guarantees) other than at stated maturity issued by
the Company which rank pari passu with or junior to such Subordinated Debt
Securities.
 
     Amendment and Assignment.  Except with respect to any changes which do not
adversely affect the rights of holders of Trust Preferred Securities of any
series (in which case no vote will be required), each Trust Guarantee with
respect to any series of Trust Preferred Securities may be changed only with the
prior approval of the holders of not less than a majority in liquidation
preference of the outstanding Trust Preferred Securities of such series. The
manner of obtaining any such approval of holders of the Trust Preferred
Securities of each series will be as set forth in an accompanying Prospectus
Supplement. All guarantees and agreements contained in each Trust Guarantee
shall bind the successors, assigns, receivers, trustees and representatives of
the Company and shall inure to the benefit of the holders of the applicable
series of Trust Preferred Securities then outstanding.
 
     Termination of the Trust Guarantees.  Each Trust Guarantee will terminate
as to the Trust Preferred Securities issued by the applicable UPRG Trust (a)
upon full payment of the redemption price of all Trust Preferred Securities of
such UPRG Trust, (b) upon distribution of the Subordinated Debt Securities held
by such UPRG Trust to the holders of the Trust Preferred Securities of such UPRG
Trust or (c) upon full payment of the amounts payable in accordance with the
Declaration of such UPRG Trust upon liquidation of such UPRG Trust. Each Trust
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any holder of Trust Preferred Securities issued by the
applicable UPRG Trust must restore payment of any sums paid under such Trust
Preferred Securities or such Trust Guarantee. The subordination provisions of
the Subordinated Debt Securities and the Trust Guarantees, respectively, will
provide that in the event payment is made on the Subordinated Debt Securities or
the Trust Guarantees in contravention of such provisions, such payments will be
paid over to the holders of Senior Indebtedness.
 
     Ranking of the Trust Guarantees.  Each Trust Guarantee will constitute an
unsecured obligation of the Company and will rank (i) subordinate and junior in
right of payment to all other liabilities of the Company,

 
                                       16
<PAGE>
(ii) pari passu with the most senior preferred or preference stock, if any,
hereafter issued by the Company and with any guarantee hereafter entered into by
the Company in respect of any preferred or preference stock or interests of any
affiliate of the Company and (iii) senior to the Company's Common Stock. Each
Declaration will provide that each holder of Trust Preferred Securities by
acceptance thereof agrees to the subordination provisions and other terms of the
applicable Trust Guarantee.
 
     Each Trust Guarantee will constitute a guarantee of payment and not of
collection. The Trust Guarantees will be deposited with the Property Trustee to
be held for the benefit of any series of Trust Preferred Securities. The
Property Trustee will have the right to enforce the Trust Guarantees on behalf
of the holders of any series of Trust Preferred Securities. The holders of not
less than 10% in aggregate liquidation preference of a series of Trust Preferred
Securities will have the right to direct the time, method and place of
conducting any proceeding for any remedy available in respect of the Trust
Guarantee applicable to such series of Trust Preferred Securities, including the
giving of directions to the Property Trustee. If the Property Trustee fails to
enforce a Trust Guarantee as above provided, any holder of Trust Preferred
Securities of a series to which such Trust Guarantee pertains may institute a
legal proceeding directly against the Company to enforce its rights under such
Trust Guarantee, without first instituting a legal proceeding against the
applicable UPRG Trust, or any other person or entity. Each Trust Guarantee will
not be discharged except by payment of the Trust Guarantee Payments in full to
the extent not paid by the applicable UPRG Trust, and by complete performance of
all obligations under such Trust Guarantee.
 
     Governing Law.  Each Trust Guarantee will be governed by and construed in
accordance with the laws of the State of New York.
 
                              PLAN OF DISTRIBUTION
 
     The Company or the UPRG Trusts may sell the Offered Securities offered
hereby (i) through underwriters or dealers, (ii) through agents, (iii) directly
to purchasers, or (iv) through a combination of any such methods of sale. Any
such underwriter, dealer or agent may be deemed to be an underwriter within the
meaning of the Securities Act. The Prospectus Supplement relating to the Offered
Securities will set forth their offering terms, including the name or names of
any underwriters, dealers or agents, the purchase price of the Offered
Securities and the proceeds to the Company or the UPRG Trusts from such sale,
any underwriting discounts, commissions and other items constituting
compensation to underwriters, dealers or agents, any initial public offering
price, any discounts or concessions allowed or reallowed or paid by underwriters
or dealers to other dealers, and any securities exchanges on which the Offered
Securities may be listed.
 
     If underwriters or dealers are used in the sale, the Offered Securities
will be acquired by the underwriters or dealers for their own account and may be
resold from time to time in one or more transactions, at a fixed price or
prices, which may be changed, or at market prices prevailing at the time of
sale, or at prices related to such prevailing market prices, or at negotiated

prices. The Offered Securities may be offered to the public either through
underwriting syndicates represented by one or more managing underwriters or
directly by one or more of such firms. Unless otherwise set forth in the
Prospectus Supplement, the obligations of underwriters or dealers to purchase
the Offered Securities will be subject to certain conditions precedent and the
underwriters or dealers will be obligated to purchase all the Offered Securities
if any are purchased. Any public offering price and any discounts or concessions
allowed or reallowed or paid by underwriters or dealers to other dealers may be
changed from time to time.
 
     Offered Securities may be sold directly by the Company or the UPRG Trusts
or through agents designated by the Company or the UPRG Trusts from time to
time. Any agent involved in the offer or sale of the Offered Securities in
respect of which this Prospectus is delivered will be named, and any commissions
payable by the Company or the UPRG Trusts to such agent will be set forth, in
the Prospectus Supplement. Unless otherwise indicated in the Prospectus
Supplement, any such agent will be acting on a best efforts basis for the period
of its appointment.
 
     If so indicated in the Prospectus Supplement, the Company or the UPRG
Trusts will authorize underwriters, dealers or agents to solicit offers by
certain specified institutions to purchase Offered Securities from the Company
or the UPRG Trusts at the public offering price set forth in the Prospectus
Supplement pursuant to
 
                                       17
<PAGE>
delayed delivery contracts providing for payment and delivery on a specified
date in the future. Such contracts will be subject to any conditions set forth
in the Prospectus Supplement and the Prospectus Supplement will set forth the
commission payable for solicitation of such contracts. The underwriters and
other persons soliciting such contracts will have no responsibility for the
validity or performance of any such contracts.
 
     Underwriters, dealers and agents may be entitled under agreements entered
into with the Company or the UPRG Trusts to indemnification by the Company or
the UPRG Trusts against certain civil liabilities, including liabilities under
the Securities Act, or to contribution by the Company or the UPRG Trusts to
payments they may be required to make in respect thereof. The terms and
conditions of such indemnification will be described in an applicable Prospectus
Supplement. Underwriters, dealers and agents may be customers of, engage in
transactions with, or perform services for, the Company or the UPRG Trusts in
the ordinary course of business.
 
     Each series of Offered Securities will be a new issue of securities with no
established trading market. Any underwriters to whom Offered Securities are sold
by the Company or the UPRG Trusts for public offering and sale may make a market
in such Offered Securities, but such underwriters will not be obligated to do so
and may discontinue any market making at any time without notice. No assurance
can be given as to the liquidity of the trading market for any Offered
Securities.
 
                                 LEGAL OPINIONS
 

     The validity of the Company Securities will be passed upon for the Company
by Mark L. Jones, General Attorney of the Company. The validity of the Trust
Preferred Securities will be passed upon for the Company and the UPRG Trusts by
Richards, Layton & Finger, Wilmington, Delaware, special Delaware counsel to the
Company and the UPRG Trusts. The validity of the Offered Securities will be
passed upon for the underwriters, dealers or agents, if any, by Cravath, Swaine
& Moore, New York, New York. Mr. Jones beneficially owns, or has rights to
acquire under employee benefit plans, an aggregate of less than 1% of the common
stock of the Company. Cravath, Swaine & Moore has from time to time acted as
counsel for the Company and may do so in the future.
 
                                    EXPERTS
 
     The financial statements incorporated in this Registration Statement by
reference from the Company's Annual Report on Form 10-K for the year ended
December 31, 1995 have been audited by Deloitte & Touche LLP, independent
auditors, as stated in their report, which is incorporated herein by reference,
and have been so incorporated in reliance upon the report of such firm given
upon their authority as experts in accounting and auditing.
 
     With respect to the unaudited interim financial information for periods
ended March 31, 1996 and 1995, June 30, 1996 and 1995 and September 30, 1996 and
1995 which is incorporated herein by reference, Deloitte & Touche LLP have
applied limited procedures in accordance with professional standards for a
review of such information. However, as stated in their reports included in the
Company's Quarterly Reports on Form 10-Q for the quarters ended March 31, 1996,
June 30, 1996 and September 30, 1996 and incorporated by reference herein, they
did not audit and they do not express an opinion on that interim financial
information. Accordingly, the degree of reliance on their reports on such
information should be restricted in light of the limited nature of the review
procedures applied. Deloitte & Touche LLP are not subject to the liability
provisions of Section 11 of the Securities Act for their reports on the
unaudited interim financial information because those reports are not 'reports'
or a 'part' of the registration statement prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Securities Act.
