series its Preferred Stock, par value $.10 per share (the "Preferred Stock"),
and its Common Stock, par value $.10 per share (the "Common Stock"), on terms to

or the equivalent thereof in one or more foreign currencies or composite

offering price of $100,000,000 plus up to an additional 4,000,000 shares. In
addition, up to 150,000 shares of Common Stock may be offered by the Selling
Stockholder of the Company. See "Selling Stockholder." The Company will not
receive any of the proceeds from the sale of such Common Stock (the "Selling
Stockholder Shares"). The Common Stock is listed on the New York Stock Exchange
(the "NYSE") under the symbol "WGR." The Debt Securities, the Preferred Stock
and the Common Stock, including the Selling Stockholder Shares except as
otherwise indicated, are hereafter collectively referred to as the "Securi
ties." The aggregate initial public offering price of all the Securities that
may be offered pursuant to this Prospectus, exclusive of the 4,000,000 shares of
Common Stock and Selling Stockholder Shares, will not exceed $300,000,000 or the
equivalent thereof.

     The accompanying Prospectus Supplement will set forth specific terms
of the Securities, including (i) in the case of Debt Securities, specific
designation, ranking as senior or subordinated Debt Securities, aggregate
principal amount, maturity, rate and time of payment of interest, purchase
price, any terms for redemption, whether and on what terms the Debt Securities
may be converted into the Company's Common Stock, and any other specific terms
of the Debt Securities, (ii) in the case of a particular series of Preferred
Stock, specific designation, aggregate number of shares offered, dividend rate
(or manner of calculation thereof), dividend periods (or manner of calculation
thereof), liquidation preference, voting rights, any terms for redemption,
whether and on what terms the shares of such series may be converted into the
Company's Common Stock at the option of the holder, whether depositary shares
representing shares of such series of Preferred Stock will be offered and, if
so, the fraction of a share of Preferred Stock represented by each depositary
share, listing, if any, on a securities exchange and any other specific terms of
such series of Preferred Stock and (iii) in the case of Common Stock, the number
of shares offered and the purchase price thereof. The accompanying Prospectus
Supplement will also set forth the name of and compensation to each dealer,
underwriter or agent, if any, involved in the sale of the Securities being
offered and the managing underwriters with respect to each series of Securities
sold to or through underwriters. The Company reserves the sole right to accept
and, together with its agents from time to time, to reject, in whole or in part,
any proposed purchase of Securities, exclusive of the Selling Stockholder
Shares, to be made directly or through agents.

 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE  SECURITIES AND
       EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE

     If an agent of the Company or, if applicable, the Selling Stockholder, or
a dealer or underwriter is involved in the sale of the Securities in respect of
which this Prospectus is being delivered, the agent's commission, dealer's
purchase price or underwriter's discount is set forth in, or may be calculated
from, the accompanying Prospectus Supplement and the net proceeds to the Company
and, if applicable, the Selling Stockholder, from such sale will be the purchase
price of such Securities less such commission in the case of an agent, the
purchase price of such Securities 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,
the other attributable issuance expenses. The Company may pay all registration

</TABLE>

     For the purpose of computing the ratio of earnings to fixed charges,
earnings consist of income before income taxes and fixed charges. For the
purpose of computing the ratio of earnings to fixed charges and preferred stock
dividends, earnings consist of income before income taxes and fixed charges and
preferred stock dividends. For purposes of calculating both ratios, fixed
charges consist of interest (including capitalized interest, but excluding
amortization of amounts previously capitalized) on all indebtedness,
amortization of debt discount and expense and that portion (one-third) of rental
expense which the Company believes to be representative of interest. For the
year ended December 31, 1995, the Company's earnings before fixed charges were
insufficient to cover its fixed charges by approximately $9.7 million. In
addition, for the years ended December 31, 1995 and 1994, the Company's earnings
before fixed charges and preferred stock dividends were insufficient to cover
its fixed charges and preferred stock dividends by approximately $30.6 million
and $9.1 million, respectively. Excluding the effect of the adoption of
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of,"
which resulted in a non-cash expense of $17.6 million, the Company's ratio of
earnings to fixed charges and ratio of earnings to fixed charges and preferred
stock dividends would have been 1.19 and .76, respectively, for the year ended
December 31, 1995. See further discussion in "Risk Factors." Statements setting
forth the unaudited computations of the consolidated ratio of earnings to fixed
charges and consolidated ratio of earnings to

                                       4

fixed charges and preferred stock dividends are filed as exhibits to the
Registration Statement of which this Prospectus is a part.

                                USE OF PROCEEDS

     Unless otherwise set forth in the accompanying Prospectus Supplement, the
net proceeds from the sale of the Securities by the Company will be used for
general corporate purposes, which may include repayment of debt, acquisitions,
working capital and capital expenditures. Pending application for specific
purposes, the net proceeds will be invested in short-term marketable securities.
The Company will not receive any of the proceeds from the sale of the Selling
Stockholder Shares.


                                 RISK FACTORS
                                        
     Prospective investors should carefully review the following factors
together with the other information contained in this Prospectus and any
accompanying Prospectus Supplement prior to making an investment decision.

Effect of Volatile Product Prices; Hedging Transactions

     The Company's future financial condition and results of operations will
depend significantly upon the prices received for the Company's natural gas and
NGLs. Prices for natural gas and NGLs are subject to fluctuations in response to
changes in supply, market uncertainty and a variety of additional factors that
are beyond the control of the Company. These factors include the level of
domestic production, the availability of imported oil and gas, actions taken by
foreign oil and gas producing nations, the availability of transportation
systems with adequate capacity, the availability of competitive fuels,
fluctuating and seasonal demand for oil, gas and NGLs, conservation and the
extent of governmental regulation of production and the overall economic
environment. A substantial or extended decline in gas and/or NGL prices would
have a material adverse effect on the Company's financial position, results of
operations and access to capital.

     The Company's risk management policy is to enter into futures, swaps and
option contracts primarily to reduce risk and lock-in profit margins on its
marketing and storage activities. Over-the-counter derivatives, with
creditworthy counterparties, also permit the Company to offer its gas customers
alternate pricing and delivery mechanisms meeting their specific needs. To
ensure a known price for future equity production and a fixed margin between gas
injected into storage and gas withdrawn from storage, the Company typically will
sell a futures contract and related basis swap and thereafter, either (i) make
physical delivery of its product to comply with such futures contract and settle
its basis swap or (ii) buy matching futures and basis position contracts to
unwind its position and sell its production to a customer in the cash market.
The Company also may contract to sell future production to a customer at a fixed
price and then purchase futures contracts to lock-in a margin. These same
techniques also may be utilized to manage price risk for product purchased from
marketing customers. Such contracts may expose the Company to the risk of
financial loss in certain circumstances, including instances where production is
less than expected, the Company's customers fail to purchase or deliver the
contracted quantities of natural gas or NGLs or credit risk with derivatives
counterparties. Furthermore, to the extent that the Company engages in hedging
activities, it may be prevented from realizing the benefits of price increases
above the levels of such hedges.

Gas Supply

     The Company must continually connect new wells to its gathering systems in
order to maintain or increase throughput levels to offset natural declines in
dedicated volumes. Historically, while certain individual plants have
experienced declines in dedicated reserves, the Company has been successful in
connecting additional reserves to more than offset the natural declines and
reserves dedicated to existing facilities. Drilling activity in certain basins
in which the Company operates has continued to be significantly reduced from
levels that existed in prior years. Higher residue gas and NGL prices
experienced since the beginning of 1996 and improved technology (e.g., 3-D
seismic and horizontal drilling) have stimulated drilling in certain of the
basins in which the Company operates, primarily the Permian and Anadarko basins.
The level of drilling will depend upon, among other factors, the prices for gas
and oil, the energy policy of the federal government and the availability of
foreign oil and gas, none of which is within the Company's control. There is no
assurance that the Company will continue to be successful in replacing the
dedicated reserves processed at its facilities.

Uncertainty of Estimates of Oil and Gas Reserves

     Reserve estimates are subject to numerous uncertainties inherent in the
estimation of quantities of proved reserves and in the projection of future
rates of production and the timing of development expenditures. The accuracy of
such estimates is a function of the quality of available data and of engineering
and geological interpretation and judgement. Reserve estimates are imprecise and
should be expected to change as additional information becomes available.
Results of subsequent drilling, testing and production may cause either upward
or downward revisions of previous estimates. In addition, the estimates of
future net revenues from proved reserves of the Company and the present value
thereof are based upon certain assumptions about production levels, prices and
costs, which may not be correct. Further, the volumes considered to be
commercially recoverable fluctuate with changes in prices and operating costs.
The meaningfulness of such estimates is highly dependent upon the accuracy of
the assumptions upon which they were based. Actual results may differ materially
from the results estimated.

     The Company has experienced unexpected water production in one of the wells
at its Black Lake Field. The Company retained an independent engineering firm to
perform an evaluation of the reserves. The evaluation has confirmed the reserves
previously estimated by the Company do not need revision at this time. The
Company will continue to monitor the field performance closely and will revise
the estimate as appropriate.

Ability to Pay Fixed Charges and Preferred Stock Dividends

     For the year ended December 31, 1995, the Company's earnings before fixed
charges were insufficient to cover its fixed charges by approximately $9.7
million. In addition, for the years ended December 31, 1995 and 1994, the
Company's earnings before fixed charges and preferred stock dividends were
insufficient to cover its fixed charges and preferred stock dividends by
approximately $30.6 million and $9.1 million, respectively. Excluding the effect
of the adoption of Statement of Financial Accounting Standards No.
121,"Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of," which resulted in a non-cash expense of $17.6
million, the Company's ratio of earnings to fixed charges and ratio of earnings
to fixed charges and preferred stock dividends would have been 1.19 and .76,
respectively, for the year ended December 31, 1995. The Company has historically
met its fixed charges, including interest, and preferred stock dividends through
cash flow from operations. There can be no assurance that the Company will have
sufficient cash flow from operations to satisfy anticipated cash 

                                       6
<PAGE>
requirements for these items and its planned capital expenditures. See "Ratio of
Earnings to Fixed Charges and Ratio of Earnings to Fixed Charges and Preferred
Stock Dividends."

Expansion Opportunities and Availability of Financing

     In order for the Company to expand its business through either the purchase
or construction of new gathering and processing facilities, the Company will be
required to identify expansion opportunities and to finance such activities,
using cash flow, equity or debt financing or a combination thereof. No assurance
can be given that appropriate opportunities for expansion at levels of
profitability which satisfy the Company's target rates can be obtained or that
financing on terms acceptable to the Company can be obtained. Natural gas and
NGL price volatility make it difficult to estimate the value of acquisitions and
to budget and forecast the return on the Company's projects. In addition,
unusually volatile prices often disrupt the market for gas and NGL properties,
as buyers and sellers have more difficulty agreeing on the purchase price of
properties.

Competition

     The Company competes with other companies in the gathering, processing and
marketing business both for supplies of natural gas and for customers for its
natural gas and NGLs. Competition for natural gas supplies is primarily based on
efficiency, reliability, availability of transportation and ability to obtain a
satisfactory price for the producers' natural gas. Competition for customers is
primarily based upon reli ability and price of deliverable natural gas and NGLs.
For customers that have the capability of using alternative fuels, such as oil
and coal, the Company also competes based primarily on price against companies
capable of providing such alternative fuels. The Company's competitors for
obtaining additional gas supplies, for gathering and processing gas and for
marketing gas and NGLs include national and local gas gatherers, brokers,
marketers and distributors of various size, financial resources and experience.
Until recently, the Company had experienced narrowing margins related to third-
party sales due to the increasing availability of pricing information in the
natural gas industry. The Company believes, by targeting end-use markets, these
margins will continue to stabilize. These sales are highly competitive and there
is no assurance that the Company will be able to expand its current end-use
business.

Environmental Matters

     The construction and operation of the Company's gathering lines, plants and
other facilities used for the gathering, transporting, processing, treating or
storing of natural gas and NGLs are subject to federal, state and local
environmental laws and regulations, including those that can impose obligations
to clean-up hazardous substances at the Company's facilities or at facilities to
which the Company sends wastes for disposal. In most instances, the applicable
regulatory requirements relate to water and air pollution control or waste
management. The Company believes that it is in substantial compliance with
applicable material environmental laws and regulations. Environmental regulation
can increase the cost of planning, designing, constructing and operating the
Company's facilities. The Company believes that the costs for compliance with
current environmental laws and regulations have not had and will not have a
material effect on the Company's financial position or results of operation.

     In 1990, the Congress enacted the Clean Air Act Amendments of 1990 (the
"Clean Air Amendments") which impose more stringent standards on emissions of
certain pollutants and establish an operating permit program for certain new and
existing air emissions sources. Under the Clean Air Amendments, individual
states are required to adopt regulations to implement the operating permit


                                       7
<PAGE>

program. The Company does not believe that compliance with the Clean Air
Amendments will require any material capital expenditures, although it will
increase permitting costs in 1996 and will increase certain operating costs,
such as emissions fees, on an on-going basis. The Company does not believe that
such cost increases will have a material effect on the Company's financial
position or results of operations.

     The Company believes that it is reasonably likely that the trend in
environmental legislation and regulation will continue to be towards stricter
standards. The Company is unaware of future environmental standards that are
reasonably likely to be adopted that will have a material effect on the
Company's financial position or results of operations, but cannot rule out that
possibility.

Regulation

     Many aspects of the gathering, processing, marketing and transportation of
natural gas and NGLs by the Company are subject to federal, state and local laws
and regulations which can have a significant impact upon the Company's overall
operations. However, the gathering, processing and marketing activities of the
Company have generally not been subject to regulation, and therefore, except as
con strained by competitive factors, the Company has considerable pricing
flexibility.

     As a processor and marketer of natural gas, the Company depends on the
transportation and storage services offered by various interstate and intrastate
pipeline companies for the delivery and sale of its own gas supplies as well as
those it processes and/or markets for others. Both the performance of
transportation and storage services by interstate pipelines and the rates
charged for such services are subject to the jurisdiction of the Federal Energy
Regulatory Commission or state regulatory agencies. An inability to obtain
transportation and/or storage services at competitive rates can hinder the
Company's processing and marketing operations and/or affect its sales margins.

Insurance and Operational Risks

     The Company is subject to various hazards which are inherent in the
industry in which it operates such as explosions, product spills, leaks and
fires, each of which could cause personal injury and loss of life, severe damage
to and destruction of property and equipment, and pollution or other
environmental damage, and may result in curtailment or suspension of operations
at the affected facility. The Company maintains physical damage, comprehensive
general liability, workers' compensation and business interruption insurance.
Such insurance is subject to deductibles that the Company considers reasonable.
The Company is not fully insured against all risks in its business, however, the
Company believes that the coverage it maintains is adequate and consistent with
other companies in the industry. Consistent with insurance coverage typically
available to the natural gas industry, the Company's insurance policies do not
provide coverage for losses or liabilities relating to pollution, except for
sudden and accidental occurrences.

                        DESCRIPTION OF DEBT SECURITIES

     The Debt Securities will be issued under an indenture (the "Indenture")
between the Company and Texas Commerce Bank National Association, as trustee
(the "Trustee"). The Debt Securities may constitute either senior or
subordinated debt of the Company as set forth in any accompanying Prospectus
Supplement for a specific series of Debt Securities. The following statements
are subject to the detailed provisions of the Indenture, a copy of the form of
which is filed as an exhibit to the Registration Statement. Wherever references
are made to particular provisions of the Indenture, such provisions are

by reference as a part of the statements made and such statements are qualified
in their entirety by such reference. Capitalized terms are defined in the
Indenture unless otherwise defined herein.

General

     The Indenture does not limit the amount of the Debt Securities which may be

pursuant to which the Debt Securities are convertible or exchangeable into
Common Stock or Preferred Stock or other debt or exchange provisions; (12) any
index or formula used to determine the amount of payments of principal of and
premium, if any, and interest on, such Debt Securities; (13) if other than the
principal amount thereof, the portion of the principal amount of such Debt
Securities that will be payable upon declaration of the acceleration of the
maturity thereof or the method by which such portion shall be determined; (14)
the person to whom any interest on any such Debt Security shall be payable if
other than the person in whose name such Debt Security is registered on the
applicable record date; (15) any addition to, or modification or deletion of,
any event of Default or any covenant of the Company specified in the Indenture
with respect to such Debt Securities; (16) the application, if any, of such

part in the form of one or more temporary or permanent global securities and, if
so, the identity of the depositary for such global security or securities; and
(18) any other specific terms of the Debt Securities. Principal, premium, if
any, and interest, if any, will be payable and the Debt Securities offered
hereby will be transferable, at the corporate trust office of the Trustee's
agent in the borough of Manhattan, the City of New York, provided that payment
of interest, if any, may be made at the option of the Company by check mailed to
the address of the person entitled thereto as it appears in the Security
Register. Unless otherwise specified in the applicable Prospectus Supplement,
the Debt Securities will not be listed on any securities exchange.

     If the accompanying Prospectus Supplement specifies that a series of Debt
Securities is denominated in a currency or currency unit other than United
States dollars, such Prospectus Supplement shall also specify the denomination
in which such Debt Securities will be issued and the coin or currency in which
the principal, premium, if any, and interest, if any, on such Debt Securities
will be payable, which may be United States dollars based upon the exchange rate
for such other currency or currency unit existing on or about the time a payment
is due. Special material United States federal income tax

          considerations applicable to any Debt Securities so denominated shall
          also be described in the applicable Prospectus Supplement.

               The Debt Securities offered hereby will be issued only in fully
          registered form without coupons and, unless otherwise specified in the
          Prospectus Supplement, in denominations of $1,000 and multiples of
          $1,000.  Debt Securities may be issued in book-entry form, without
          certificates.  Any such issue will be described in the Prospectus
          Supplement relating to such Debt Securities.  No service charge will
          be made for any transfer or exchange of the Debt Securities, but the
          Company or the Trustee may require payment of a sum sufficient to
          cover any tax or other government charge payable in connection
          therewith.

               Debt Securities may be issued under the Indenture as Original
          Issue Discount Securities to be sold at a substantial discount from
          their stated principal amount.  Material federal income tax
          consequences and other considerations applicable thereto will be
          described in the applicable Prospectus Supplement.

               The Indenture contains no covenants or other provisions affording
          protection to holders of the Debt Securities in the event of a highly
          leveraged transaction, other transactions that may adversely affect
          the Holders or a change in control of the Company, except to the
          limited extent described under "Limitations on Mergers and Sales of
          Assets."

          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 "Global Depositary"), or its
          nominee, identified in the Prospectus Supplement relating to such
          series.  In such a case, one or more Global Securities will be issued
          in a denomination or aggregate denomination equal to the portion of
          the aggregate principal amount of Outstanding Debt Securities of the
          series to be represented by such Global Security or Securities.
          Unless and until it is exchanged in whole or in part for Debt
          Securities in definitive registered form, a Global Security may not be
          registered for transfer or exchange except as a whole by the Global
          Depositary for such Global Security to a nominee for such Global
          Depositary and except in the circumstances described in the applicable
          Prospectus Supplement.

               The specific terms of the depositary arrangement with respect to
          any portion of a series of Debt Securities to be represented by a
          Global Security and a description of the Global Depositary will be
          provided in the applicable Prospectus Supplement.

          Senior Debt

               The Debt Securities that will be designated and will constitute
          part of the Senior Indebtedness (hereafter defined) of the Company,
          will rank pari passu with all other unsecured and unsubordinated debt
          of the Company.

          Subordinated Debt

               The Debt Securities that will constitute part of the subordinated
          debt of the Company (the "Subordinated Debt Securities"), will be
          subordinated in right of payment, as set forth in the Indenture, to
          the prior payment in full of all existing and future Senior
          Indebtedness of the Company.  "Senior Indebtedness" means the
          principal of (and premium, if any) and interest on (including interest
          accrued after the filing of a petition initiating any proceeding
          pursuant to any Bankruptcy Law, but only to the extent

                                       10
<PAGE>
 
          allowed or permitted to the holder of such Indebtedness against the
          bankruptcy or any other insolvency estate of the Company in such
          proceeding) or accrued Original Issue Discount on and other amounts
          due on or in connection with any Indebtedness incurred, assumed or
          guaranteed by the Company, whether outstanding on the date of the
          Indenture or thereafter incurred, assumed or guaranteed, and all
          renewals, extensions and refunding of any such Indebtedness; provided,
          however, that the following will not constitute Senior Indebtedness:
          (a) any Indebtedness which expressly provides (i) that such
          Indebtedness shall not be senior in right of payment to the
          Subordinated Debt Securities or (ii) that such Indebtedness shall be
          subordinated to any other Indebtedness of the Company, unless such
          Indebtedness expressly provides that such Indebtedness shall be senior
          in right of payment to the Subordinated Debt Securities; (b) any
          Indebtedness or liability for compensation to employees, for goods or
          materials purchased in the ordinary course of business or for
          services; (c) any Indebtedness of the Company to any Subsidiary for
          money borrowed or advanced from such Subsidiary; and (d) any liability
          for federal, state, local or other taxes owed or owing by the Company.
          "Indebtedness" means any and all obligations of a corporation for
          money borrowed which in accordance with generally accepted accounting
          principles would be reflected on the balance sheet of such corporation
          as a liability on the date as of which Indebtedness is to be
          determined.

               By reason of the subordination described herein, in the event of
          insolvency, upon any distribution of the assets of the Company, (i)
          the Holders of the Subordinated Debt Securities are required to pay
          over their share of such distribution to the trustee in bankruptcy,
          receiver or other person distributing the assets of the Company for
          application to the payment of all Senior Indebtedness remaining
          unpaid, to the extent necessary to pay all holders of Senior
          Indebtedness in full and (ii) unsecured creditors of the Company who
          are not Holders of Subordinated Debt Securities or Holders of Senior
          Indebtedness of the Company may recover less, ratably, than Holders of
          Senior Indebtedness of the Company and may recover more, ratably, than
          the Holders of Subordinated Debt Securities.

               In the event that the Subordinated Debt Securities are declared
          due and payable prior to their Stated Maturity by reason of the
          occurrence of an Event of Default, then the Company is obligated to
          notify promptly holders of Senior Indebtedness of such acceleration.
          The Company may not pay the Subordinated Debt Securities until 120
          days have passed after such acceleration occurs and may thereafter pay
          the Subordinated Debt Securities if the terms of the Indenture
          otherwise permit payment at that time.

               No payment of the principal amount at maturity, Issue Price plus
          accrued Original Issue Discount, in the case of Original Issue
          Discount Securities, any redemption price, or interest, if any, in
          respect of the Subordinated Debt Securities may be made, nor may the
          Company otherwise acquire any Subordinated Debt Securities except as
          set forth in the Indenture, if any default with respect to Senior
          Indebtedness occurs and is continuing that permits the acceleration of
          the maturity thereof and the Company has actual knowledge of the
          default, unless (a) 120 days pass after notice of the default is given
          to the Trustee and such default is not then the subject of judicial
          proceedings or the default with respect to the Senior Indebtedness is
          cured (including, without limitation, by the payment of such Senior
          Indebtedness in full) or waived and (b) the terms of the Indenture
          otherwise permit the payment or acquisition of the Subordinated Debt
          Securities at that time.  The Company is required to give the Trustee
          notice of a default with respect to Senior Indebtedness within five
          Business Days after the Company has actual knowledge of the default.

               If this Prospectus is being delivered in connection with a series
          of Subordinated Debt Securities, the accompanying Prospectus
          Supplement or the information incorporated herein by reference will
          set forth

                                       11
<PAGE>
 
          the approximate amount of Senior Indebtedness outstanding as of the
          end of the most recent fiscal quarter for which the Company has filed
          an Annual Report on Form 10-K or a Quarterly Report on Form 10-Q.

          Conversion or Exchange of Debt Securities

               No series of Debt Securities will be convertible into, or
          exchangeable for, other securities or properties except as set forth
          in the applicable Prospectus Supplement.

          Certain Covenants Applicable to Senior Debt Securities

               Unless otherwise set forth in the applicable Prospectus
          Supplement, the following covenants will be applicable to Debt
          Securities that constitute Senior Indebtedness.

               Limitations on Liens.  The Company will not, and will not permit
          any Restricted Subsidiary to, incur, issue, assume or guarantee any
          Indebtedness secured by a Lien on any Restricted Property, or on any
          shares of stock or Indebtedness of a Restricted Subsidiary, without
          providing that the Debt Securities shall be secured equally and
          ratably with (or prior to) such secured Indebtedness, unless after
          giving effect thereto the aggregate amount of all such Indebtedness so
          secured (other than Indebtedness secured by excepted Liens referred to
          in the following sentence), together with all Attributable Debt of the
          Company and its Restricted Subsidiaries in respect of Sale-Leaseback
          Transactions except Sale-Leaseback Transactions the proceeds of which
          are applied to the retirement of Funded Debt, would not exceed 10% of
          Consolidated Adjusted Net Assets as shown on the Company's latest
          audited consolidated financial statements.  This restriction will not
          apply to (a) Liens on property of, or on any shares of stock or
          Indebtedness of, any corporation existing at the time such corporation
          becomes a Subsidiary, (b) Liens on property existing at the time of
          acquisition thereof (including acquisition through merger or
          consolidation) or to secure the payment of all or any part of the
          purchase price or construction cost thereof or to secure any
          Indebtedness incurred prior to, at the time of, or within six months
          after such acquisition or completion of such property for the purpose
          of financing all or any part of the purchase price or construction
          cost thereof, (c) Liens on substantially unimproved property to secure
          the cost of exploration, drilling or development of, or improvements
          to, such property, (d) Liens in favor of the Company or a Restricted
          Subsidiary, and (e) any extension, renewal or replacement of any Lien
          referred to in the foregoing clauses (a) through (d) inclusive,
          provided that such extension, renewal or replacement Liens shall be
          limited to all or part of the same property that secured the Liens
          extended, renewed or replaced (plus improvements on such property).
          The following types of transactions are not deemed to create
          Indebtedness secured by a Lien:  (i) a sale or transfer of crude oil,
          natural gas or NGLs in place for a period of time until, or in an
          amount such that, the purchaser will realize therefrom a specified
          amount of money or of such oil, natural gas or NGLs, or any other
          interest in property commonly referred to as a "production payment,"
          or (ii) the Lien on any property of the Company or any Subsidiary in
          favor of governmental bodies to secure partial, progress, advance or
          other payments to the Company or any Subsidiary pursuant to any
          contract or statute, or the Lien of any property to secured
          Indebtedness of the pollution control or industrial revenue bond type.

               Limitation on Sale-Leaseback Transactions.  The Indenture
          provides that the Company shall not, and it shall not permit any
          Restricted Subsidiary to, enter into a Sale-Leaseback Transaction
          unless:  (1) the lease has a term of three years or less; (2) the
          lease is between the Company and a Restricted Subsidiary or between
          Restricted Subsidiaries; (3) the Company or a Restricted Subsidiary
          could create a Lien under the terms of the Indenture on the Restricted
          Property to secure Funded Debt at least equal in amount to the
          Attributable Debt for the lease; or (4) the Company or a Restricted
          Subsidiary could

                                       12
<PAGE>
 
          create a Lien on Restricted Property under the terms of the Indenture
          to secure Funded Debt at least equal in amount to the Attributable
          Debt for the lease without having to secure equally and ratably any
          Debt Securities that constitute Senior Indebtedness or (5) the Company
          or a Restricted Subsidiary within 120 days of the effective date of
          the Sale-Leaseback Transaction (i) retires Funded Debt of the Company
          or of a Restricted Subsidiary at least equal in amount to the fair
          value (as determined by the Company's Board of Directors) of the
          Restricted Property at the time of the Sale-Leaseback Transaction or
          (ii) if the net proceeds of the Sale-Leaseback Transaction equal or
          exceed the fair value of the Restricted Property (as determined by the
          Company's Board of Directors), applies the net proceeds to fund
          investment in other Restricted Properties which investments were made
          within 12 months prior to or subsequent to the Sale-Leaseback
          Transaction.

          Limitation on Mergers and Sales of Assets

               The Company shall not consolidate with, merge with, or merge into
          any corporation or convey or transfer its properties and assets
          substantially as an entirety to any Person unless the successor entity
          shall be a corporation organized under the laws of the United States
          or any state or the District of Columbia and shall expressly assume
          the obligations of the Company under the Indenture.  If, with respect
          to Debt Securities that constitute Senior Indebtedness, upon any such
          consolidation, merger, conveyance or transfer of the Company with or
          into any Person or of any such Subsidiary with or to any other
          Subsidiary, any Property of the Company or of any Restricted
          Subsidiary or any shares of stock or indebtedness of any Restricted
          Subsidiary would thereupon become subject to any Lien (other than a
          Lien permitted under "Limitation on Liens" without the Company's
          having to secure such Debt Securities equally and ratably), the
          Company will secure such Debt Securities (together with, if the
          Company shall so determine, other securities ranking on a parity with
          such Debt Securities) prior to all Liens other than any theretofore
          existing.

               Although the amount of the Company's property that will
          constitute a sale of such property "substantially as an entirety" is
          not readily quantifiable, a determination whether such a sale has
          occurred will depend on the percentage of operating and total assets
          transferred, among other measurements, and other facts and
          circumstances of the transaction.  In any particular transaction, this
          determination will be made by the Company and, if such a transaction
          occurs, the person to which such amount of the Company's property is
          transferred shall enter into a supplemental Indenture satisfactory in
          form to the Trustee.

          a party where the Company or a Restricted Subsidiary now owns or
          hereafter acquires a Restricted Property, transfers it to a lender, or
          to any person to whom funds have been or are to be advanced by a
          lender on the security of such Restricted Property on the rental

          Events of Default

               The following are Events of Default under the Indenture with
          respect to Debt Securities of any series:  (a) failure to pay
          principal of or premium, if any, on any Debt Security of that series
          at its Maturity (in the case of any Subordinated Debt Securities,
          whether or not payment is prohibited by the provisions described under
          "Subordinated Debt"); (b) failure to pay any interest on any Debt
          Security of that series when due, continued for 30 days (in the case
          of any Subordinated Debt Securities, whether or not payment is
          prohibited by the provisions described under "Subordinated Debt"); (c)
          failure to deposit any sinking fund payment, when due, in respect of
          any Debt Security of that series (in the case of any Subordinated Debt
          Securities, whether or not payment is prohibited by the provisions
          described under "Subordinated Debt"); (d) any other defaults in the
          performance, or breach, of any covenant of the Company in the
          Indenture, continued for 90 days after notice of such default or
          breach from the Trustee or the Holders of at least 25% in principal
          amount of the Outstanding Debt Securities of that series (other than a
          covenant included in the Indenture solely for the benefit of any
          series of Debt Securities other than that series); (e) certain events
          of bankruptcy, insolvency or reorganization; and (f) any other Event
          of Default provided with respect to Debt Securities of that series.

                                       14
<PAGE>
 
               If an Event of Default with respect to Outstanding Debt
          Securities of any series shall occur and be continuing, either the
          Trustee or the Holders of at least 25% in principal amount of the
          Outstanding Debt Securities of that series may declare the principal
          amount (or, if the Debt Securities of that series are Original Issue
          Discount Securities, such portion of the principal amount as may be
          specified in the terms of that series) of all Debt Securities of that
          series to be due and payable immediately.  However, at any time after
          a declaration of acceleration with respect to Debt Securities of any
          series has been made, but before a judgment or decree based on such
          acceleration has been obtained, the Holders of a majority in principal
          amount of Outstanding Debt Securities of that series may, under
          certain circumstances, rescind and annul such acceleration.
          Notwithstanding the foregoing, if any Subordinated Debt Securities are
          declared due and payable prior to their Stated Maturity by reason of
          the occurrence of an Event of Default, the Company may not pay the
          Subordinated Debt Securities until 120 days have passed after such
          acceleration occurs and may thereafter pay the Subordinated Debt
          Securities if the terms of the Indenture otherwise permit payment at
          the time.  See "Subordinated Debt."  For information as to waiver of
          defaults, see "Modification and Waiver."

               The Indenture provides that, subject to the provisions of the
          Trust Indenture Act of 1939, as amended, the Trustee will be under no
          obligation to exercise any of its rights or powers under the Indenture
          at the request or direction of any of the Holders, unless such Holders
          shall have offered to the Trustee reasonable indemnity.  Subject to
          such provisions for indemnification of the Trustee, the Holders of a
          majority in principal amount of the Outstanding Debt Securities of any
          series will have the right to direct the time, method and place of
          conducting any proceeding for any remedy available to the Trustee, or
          exercising any trust or power conferred on the Trustee, with respect
          to the Debt Securities of that series.

               The Company will be required to furnish annually to the Trustee a
          statement as to the performance by the Company of certain of its
          obligations under the Indenture and as to any default in such
          performance.

          Modification and Waiver

               Modifications and amendments to the Indenture may be made by the
          Company and the Trustee with the consent of the Holders of a majority
          in principal amount of the Debt Securities of each series affected
          thereby; provided, however, that no such modification or amendment
          may, without the consent of the Holder of each Outstanding Debt
          Security affected thereby, (a) change the Stated Maturity of the
          principal of, or any installment of principal of or interest on, any
          Debt Security, (b) reduce the principal amount of, or the premium, if
          any, or interest, if any, on, any Debt Security, (c) reduce the amount
          of principal of any Original Issue Discount Security payable upon
          acceleration of the Maturity thereof, (d) change the coin or currency
          in which any Debt Securities or premium, if any, or interest, if any,
          thereon is payable, (e) in the case of convertible Debt Securities,
          adversely affect the right to convert any Debt Security, or (f) reduce
          the percentage in principal amount of Outstanding Debt Securities of
          any series, the consent of the Holders of which is required for (i)
          modification or amendment of the Indenture, (ii) in the case of any
          Subordinated Debt Securities, modification of the subordination
          provisions  in a manner adverse to the Holders of the Subordinated
          Debt Securities, (iii) waiver of compliance with certain provisions of
          the Indenture, or (iv) waiver of certain defaults.

               Modifications and amendments of the Indenture may be made by the
          Company and the Trustee without the consent of any Holder to evidence
          a successor to the Company, to add to, modify or delete any of the
          Company's covenants or Events of Default, to permit or facilitate Debt
          Securities to be issued by book entry or in bearer form or relating to
          the place of payment thereof, to provide for a successor trustee,

                                       15
<PAGE>
 
          to establish forms or terms of Debt Securities, to change or eliminate
          any provision not adversely affecting any interests of Holders of
          Outstanding Debt Securities in any material respect or to cure any
          ambiguity or inconsistency.

               The Holders of a majority in principal amount of the Outstanding
          Debt Securities of any series may on behalf of the Holders of all Debt
          Securities of that series waive, insofar as that series is concerned,
          compliance by the Company with certain restrictive provisions of the
          Indenture.  The Holders of a majority in principal amount of the
          Outstanding Debt Securities of any series may on behalf of the Holders
          of all Debt Securities of that series waive any past default under the
          Indenture with respect to Debt Securities of that series, except a
          default in the payment of the principal of, or premium, if any, or
          interest, if any, on, any Debt Security of that series or in respect
          to any provision which under the Indenture cannot be modified or
          amended without the consent of the Holder of each Outstanding Debt
          Security of that series affected.

          Defeasance

               The following provisions of the Indenture are applicable to the
          Debt Securities.  The Company (a) shall be discharged from its
          obligations in respect of the Debt Securities of such series
          ("defeasance and discharge"), or (b) may cease to comply with certain
          restrictive covenants ("covenant defeasance") including those
          described under "Certain Covenants" and "Limitations on Mergers and
          Sales of Assets" and, in the case of any Subordinated Debt Securities,
          the provisions described under "Subordinated Debt," and any such
          omission shall not be an Event of Default with respect to the Debt
          Securities of such series, in each case at any time prior to the
          Stated Maturity or redemption thereof, when the Company has
          irrevocably deposited with the Trustee, in trust, (i) sufficient funds
          in the currency or currency unit in which the Debt Securities are
          denominated to pay the principal of (and premium, if any), and
          interest to Stated Maturity (or redemption) on, the Debt Securities of
          such series, or (ii) 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, and which are not subject to
          prepayment, redemption or call, as will, together with the
          predetermined and certain income to accrue thereon without
          consideration of any reinvestment thereof, be sufficient to pay when
          due the principal of (and premium, if any), and interest to Stated
          Maturity (or redemption) on, the Debt Securities of such series.  Such
          defeasance and discharge and covenant defeasance are conditioned upon,
          among other things, the Company's delivery of (i) an opinion of
          counsel that the Holders of the Debt Securities will not recognize
          income, gain or loss for United States federal income tax purposes as
          a result of such defeasance, and will be taxed in the same manner as
          if no defeasance and discharge or covenant defeasance, as the case may
          be, had occurred and (ii) an opinion of counsel that such defeasance
          would not cause the Debt Securities to be delisted from any national
          securities exchange on which such Debt Securities may then be listed.
          Upon such defeasance and discharge, the Holders of the Debt Securities
          of such series shall no longer be entitled to the benefits of the
          Indenture, except for the purposes of registration of transfer and
          exchange of the Debt Securities of such series and replacement of
          lost, stolen or mutilated Debt Securities and shall look only to such
          deposited funds or obligations for payment.

          Governing Law

               The Indenture and Debt Securities will be governed by, and
          construed in accordance with, the laws of the State of New York.

          The Trustee

               The Company may have customary banking relationships with the
          Trustee in the ordinary course of business.


                         DESCRIPTION OF CAPITAL STOCK

               The Company is authorized to issue up to 100,000,000 shares of
          Common Stock, par value $.10 per share, and up to 10,000,000 shares of
          Preferred Stock, par value $.10 per share.  As of March 31, 1996,
          there were 25,773,553 shares of Common Stock outstanding.  The Company
          also had outstanding on such date  1,400,000 shares of $2.28
          Cumulative Preferred Stock with a liquidation preference of $25 per
          share (the "$2.28 Preferred Stock") and 2,760,000 shares of $2.625
          Cumulative Convertible Preferred Stock with a liquidation preference
          of $50 per share (the "$2.625 Convertible Preferred Stock").  Unless
          otherwise provided in any Prospectus Supplement for a series of
          Preferred Stock offered hereby (the "Offered Preferred Stock"), the
          $2.28 Preferred Stock and the $2.625 Preferred Stock (collectively,
          the "Existing Preferred Stock") will rank on a parity with the Offered
          Preferred Stock.

               The Board of Directors of the Company has the power, without
          further action by the stockholders unless action is required by
          applicable laws or regulations or by the terms of any outstanding
          Preferred Stock,  to issue Preferred Stock in one or more series and
          to fix the designations, preferences and voting rights, and relative,
          participating, optional and other special rights, and the
          qualifications, limitations and restrictions applicable thereto. The
          rights of holders of any Offered Preferred Stock will be subject to,
          and may be adversely affected by, the rights of holders of any
          Preferred Stock which may be issued in the future.  The Board of
          Directors may cause Preferred Stock to be issued to obtain additional
          financing, in connection with acquisitions and for other proper
          corporate purposes.  Issuance of shares of Preferred Stock by the
          Company may have the effect, under certain circumstances, alone or in
          combination with certain of the provisions of the Company's
          Certificate of Incorporation, as amended (the "Certificate of
          Incorporation"), described below, of rendering more difficult or
          discouraging an acquisition of the Company deemed undesirable by the
          Board of Directors.

               The following summary does not purport to be complete and is,
          subject to, and qualified in its entirety by, the Company's
          Certificate of Incorporation, including the Certificate of Designation
          relating to a specific series of the Offered Preferred Stock (the
          "Certificate of Designation"), which will be in the form filed as an
          exhibit to or incorporated by reference in the Registration Statement
          of which this Prospectus is a part at or prior to the time of issuance
          of such series of Offered Preferred Stock, the Certificate of
          Designation of the $2.28 Preferred Stock and the Certificate of
          Designation of the $2.625 Convertible Preferred Stock.

          Offered Preferred Stock

               The following is a description of certain general terms and
          provisions of the Offered Preferred Stock.  The particular terms of
          any series of Offered Preferred Stock will be described in the
          applicable Prospectus Supplement.  If so indicated in a Prospectus
          Supplement, the terms of any such series may differ from the terms set
          forth below.  The summary of terms of the Company's Offered Preferred
          Stock contained in this Prospectus does not purport to be complete and
          is subject to, and qualified in its entirety by, the provisions of the
          Company's Certificate of Incorporation and the Certificate of
          Designation.

<PAGE>
 
               The Board of Directors is authorized to determine for each series
          of Offered Preferred Stock, and the Prospectus Supplement shall set
          forth with respect to such series: (i) the number of shares that
          constitute such series, (ii) the dividend rate (or the method of
          calculation thereof) on the shares of such series, (iii) the dividend
          periods (or the method of calculation thereof), (iv) the voting rights
          of the shares, (v) the liquidation preference and any other rights of
          the shares of such series upon any liquidation or winding-up of the
          Company, (vi) whether or not and on what terms the shares of such
          series will be subject to redemption at the option of the Company,
          (vii) whether and on what terms the shares of such series will be
          convertible into shares of Common Stock of the Company, (viii) whether
          depositary shares representing shares of such series of Preferred
          Stock will be offered and, if so, the fraction of a share of such
          series of Offered Preferred Stock represented by each depositary share
          (see "Depositary Shares" below), (ix) whether the shares of such
          series of Offered Preferred Stock will be listed on a securities
          exchange and (x) the other rights and privileges and any
          qualifications, limitations or restrictions of such rights or
          privileges of such series.

                    Dividends

               Holders of shares of Offered Preferred Stock shall be entitled to
          receive, when and as declared by the Board of Directors out of funds
          of the Company legally available therefor, an annual cash dividend
          payable at such dates and at such rates per share per annum as set
          forth in the applicable Prospectus Supplement.

               Unless otherwise set forth in the applicable Prospectus
          Supplement, each series of Offered Preferred Stock will be junior as
          to dividends to any Preferred Stock that may be issued in the future
          that is expressly senior as to dividends to the Offered Preferred
          Stock. If at any time the Company has failed to pay accrued dividends
          upon any such senior shares at the time such dividends are payable,
          the Company may not pay any dividend on the Offered Preferred Stock or
          redeem or otherwise repurchase shares of Offered Preferred Stock until
          such accumulated but unpaid dividends on such senior shares have been
          paid or set aside for payment in full by the Company.

               No dividends may be declared or paid or set apart for payment on
          any Preferred Stock, including the Existing Preferred Stock, ranking
          on parity as to dividends with the Offered Preferred Stock unless
          there shall also be or have been declared and paid or set apart for
          payment on the outstanding shares of Offered Preferred Stock dividends
          for all dividend payment periods of the Offered Preferred Stock ending
          on or before the dividend payment date of such parity Preferred Stock,
          ratably in proportion to the respective amounts of dividends, (i)
          accumulated and unpaid or payable on such parity Preferred Stock, on
          the one hand, and (ii) accumulated and unpaid or payable through the
          dividend payment period of the Offered Preferred Stock next preceding
          such dividend payment date, on the other hand. Except as set forth
          above, dividends (other than in Common Stock) may not be paid or
          declared and set aside for payment and other distributions may not be
          made upon the Common Stock or on any other Preferred Stock of the
          Company ranking junior to or on parity as to dividends with the
          Offered Preferred Stock, including the Existing Preferred Stock, nor
          may any Common Stock or such other Preferred Stock of the Company be
          redeemed, purchased or otherwise acquired by the Company for any
          consideration or any payment be made to or available for a sinking
          fund for the redemption of any shares of such stock; provided,
          however, that any monies theretofore deposited in any sinking fund
          with respect to any Preferred Stock in compliance with the provisions
          of such sinking fund may thereafter be applied to the purchase or
          redemption of such Preferred Stock in accordance with the terms of
          such sinking fund, regardless of whether at the time of such
          applications full cumulative dividends upon shares of the Offered
          Preferred Stock outstanding on the last dividend payment date shall
          have been paid or declared and set apart for payment; and provided,

                                       18
<PAGE>
 
          further, that any such junior or parity Preferred Stock or Common
          Stock may be converted into or exchanged for stock of the Company
          ranking junior to the Offered Preferred Stock as to dividends.

               The amount of dividends payable for the initial dividend period
          or any period shorter than a full dividend period shall  be computed
          on the basis of a 360-day year of twelve 30-day months.  Accrued but
          unpaid dividends will not bear interest.

               Convertibility

               No series of Offered Preferred Stock will be convertible into, or
          exchangeable for, other securities or property except as set forth in
          the applicable Prospectus Supplement.

               Redemption and Sinking Fund

               No series of Offered Preferred Stock will be redeemable or
          receive the benefit of a sinking fund except as set forth in the
          applicable Prospectus Supplement.

               Liquidation Rights

               In the event of any liquidation, dissolution or winding up of the
          Company, the holders of shares of each series of Offered Preferred
          Stock are entitled to receive out of assets of the Company available
          for distribution to stockholders, before any distribution of assets is
          made to holders of: (i) any other shares of Preferred Stock ranking
          junior to such series of Offered Preferred Stock as to rights upon
          liquidation, dissolution or winding up and (ii) Common Stock,
          liquidating distributions per share in the amount of the liquidation
          preference specified in the applicable Prospectus Supplement for such
          series of Offered Preferred Stock plus dividends accrued and
          accumulated but unpaid to the date of final distribution; but the
          holders of each series of Offered Preferred Stock will not be entitled
          to receive the liquidating distribution of, plus such dividends on,
          such shares until the liquidation preference of any shares of the
          Company's capital stock ranking senior to such series of the Offered
          Preferred Stock as to the rights upon liquidation, dissolution or
          winding up shall have been paid (or a sum set aside therefor
          sufficient to provide for payment) in full. If upon any liquidation,
          dissolution or winding up of the Company, the amounts payable with
          respect to the Offered Preferred Stock, the Existing Preferred Stock
          and any other Preferred Stock ranking as to any such distribution on a
          parity with the Offered Preferred Stock are not paid in full, the
          holders of the Offered Preferred Stock, the Existing Preferred Stock
          and such other parity Preferred Stock will share ratably in any such
          distribution of assets in proportion to the full respective
          preferential amount to which they are entitled. Unless otherwise
          specified in a Prospectus Supplement for a series of Offered Preferred
          Stock, after payment of the full amount of the liquidating
          distribution to which they are entitled, the holders of shares of
          Offered Preferred Stock will not be entitled to any further
          participation in any distribution of assets by the Company. Neither a
          consolidation or merger of the Company with another corporation nor a
          sale of securities shall be considered a liquidation, dissolution or
          winding up the Company.

               Voting Rights

               Holders of Offered Preferred Stock will not have any voting
          rights except as set forth below or in the applicable Prospectus
          Supplement or as otherwise from time to time required by law. Whenever
          dividends on any applicable series of Offered Preferred Stock or any
          other class or series of stock ranking on a parity with the applicable
          series of Offered Preferred Stock with respect to the payment of
          dividends

                                       19
<PAGE>
 
          shall be in arrears for dividend periods, whether or not consecutive
          containing in the aggregate a number of days equivalent to six
          calendar quarters, the holders of shares of such series of Offered
          Preferred Stock (voting separately as a class with all other series of
          Preferred Stock, upon which like voting rights have been conferred and
          are exercisable) will be entitled to vote for the election of two of
          the authorized number of directors of the Company at the next annual
          meeting of stockholders and at each subsequent meeting until all
          dividends accumulated on such series of Offered Preferred Stock shall
          have been fully paid or set apart for payment. The term of office of
          all directors elected by the holders of such Offered Preferred Stock
          shall terminate immediately upon the termination of the rights of the
          holders of such Offered Preferred Stock to vote for directors. Unless
          otherwise set forth in the applicable Prospectus Supplement, holders
          of shares of Offered Preferred Stock will have one vote for each share
          held.

               So long as any shares of any series of Offered Preferred Stock
          remain outstanding, the Company shall not, without the consent of
          holders of at least two-thirds of the shares of such series of Offered
          Preferred Stock outstanding at the time, voting separately as a class
          with all other series of Preferred Stock upon which like voting rights
          have been conferred and are exercisable (i) issue or increase the
          authorized amount of any class or series of stock ranking prior to the
          outstanding Offered Preferred Stock as to dividends or upon
          liquidation or (ii) amend, alter or repeal the provisions of the
          Company's Certificate of Incorporation or of the resolutions contained
          in the Certificate of Designation relating to such series of Offered
          Preferred Stock, whether by merger, consolidation or otherwise, so as
          to materially adversely affect any power, preference or special right
          of such series of Offered Preferred Stock or the holders thereof;
          provided, however, that any increase in the amount of the authorized
          Common Stock or authorized Preferred Stock or any increase or decrease
          in the number of shares of any series of Preferred Stock or the
          creation and issuance of other series of Common Stock or Preferred
          Stock ranking on a parity with or junior to Preferred Stock as to
          dividends and upon liquidation, dissolution or winding up shall not be
          deemed to materially adversely affect such powers, preferences or
          special rights.

               Miscellaneous

               The holders of Offered Preferred Stock will have no preemptive
          rights. Offered Preferred Stock, upon issuance against full payment of
          the purchase price therefor, will be fully paid and nonassessable.
          Shares of Offered Preferred Stock redeemed or otherwise reacquired by
          the Company shall resume the status of authorized and unissued shares
          of Offered Preferred Stock undesignated as to series, and shall be
          available for subsequent issuance. There are no restrictions on
          repurchase or redemption of the Offered Preferred Stock while there is
          any arrearage on sinking fund installments except as may be set forth
          in an applicable Prospectus Supplement. Neither the par value nor the
          liquidation preference is indicative of the price at which the Offered
          Preferred Stock will actually trade on or after the date of issuance.
          Payment of dividends on any series of Offered Preferred Stock may be
          restricted by loan agreements, indentures and other transactions
          entered into by the Company. The accompanying Prospectus Supplement or
          information incorporated by reference will describe any material
          contractual restrictions on dividend payments.

               No Other Rights

               The shares of a series of Offered Preferred Stock will not have
          any preferences, voting powers or relative, participating, optional or
          other special rights except as set forth above or in the applicable
          Prospectus Supplement, the Certificate of Incorporation or Certificate
          of Designation or as otherwise required by law.

               Transfer Agent and Registrar

               The transfer agent and registrar for each series of Offered
          Preferred Stock will be designated in the applicable Prospectus
          Supplement.

          Depositary Shares

               General

               The Company may, at its option, elect to offer fractional shares
          of the Offered Preferred Stock, rather than full shares of the Offered
          Preferred Stock. In the event such option is exercised, the Company
          will issue receipts for Depositary Shares, each of which will
          represent a fraction (to be set forth in the Prospectus Supplement
          relating to a particular series of Offered Preferred Stock) of a share
          of a particular series of Preferred Stock as described below.

               The shares of any series of Offered Preferred Stock represented
          by Depositary Shares will be deposited under a Deposit Agreement (the
          "Deposit Agreement") among the Company, a depositary to be named in
          the applicable Prospectus Supplement (the "Preferred Stock
          Depositary"), and the holders from time to time of depositary receipts
          issued thereunder. Subject to the terms of the Deposit Agreement, each
          holder of a Depositary Share will be entitled, in proportion to the
          applicable fraction of a share of Offered Preferred Stock represented
          by such Depositary Share, to all the rights and preferences of the
          Offered Preferred Stock represented thereby (including dividend,
          voting, redemption, subscription and liquidation rights).

               The Depositary Shares will be evidenced by depositary receipts
          issued pursuant to the Deposit Agreement ("Depositary Receipts").
          Depositary Receipts will be distributed to those persons purchasing
          the fractional shares of the related series of Offered Preferred
          Stock. Copies of the forms of Deposit Agreement and Depositary Receipt
          are filed as an exhibit to the Registration Statement of which this
          Prospectus is a part, and the following summary is qualified in its
          entirety by reference to such exhibit. Immediately following the
          issuance of shares of a series of Offered Preferred Stock by the
          Company, the Company will deposit such shares with the Preferred Stock
          Depositary, which will then issue and deliver the Depositary Receipts
          to the purchasers thereof. Depositary Receipts will only be issued
          evidencing whole Depositary Shares. A Depositary Receipt may evidence
          any number of whole Depositary Shares.

               Pending the preparation of definitive Depositary Receipts, the
          Preferred Stock Depositary may, upon the written order of the Company,
          issue temporary Depositary Receipts substantially identical to (and
          entitling the holders thereof to all the rights pertaining to) the
          definitive Depositary Receipts but not in definitive form. Definitive
          Depositary Receipts will be prepared thereafter without unreasonable
          delay, and such temporary Depositary Receipts will be exchangeable for
          definitive Depositary Receipts at the Company's expense.

               Dividends and Other Distributions

               The Preferred Stock Depositary will distribute all cash dividends
          or other cash distributions received in respect of the related series
          of Offered Preferred Stock to the record holders of Depositary Shares
          relating to such series of Offered Preferred Stock in proportion to
          the number of such Depositary Shares owned by such holders.

                                       21
<PAGE>
 
               In the event of a distribution other than in cash, the Preferred
          Stock Depositary will distribute property received by it to the record
          holders of Depositary Shares entitled thereto in proportion to the
          number of Depositary Shares owned by such holders, unless the
          Preferred Stock Depositary determines that such distribution cannot be
          made proportionately among such holders or that it is not feasible to
          make such distributions, in which case the Preferred Stock Depositary
          may, with the approval of the Company, adopt such method as it deems
          equitable and practicable for the purpose of effecting such
          distribution, including the sale (at public or private sale) of the
          Securities or property thus received, or any part thereof, at such
          place or places and upon such terms as it may deem proper.

               The amount distributed in any of the foregoing cases will be
          reduced by any amounts required to be withheld by the Company or the
          Preferred Stock Depositary on account of taxes or other governmental
          charges.

               Redemption of Depositary Shares

               If a series of the Offered Preferred Stock underlying the
          Depositary Shares is subject to redemption, the Depositary Shares will
          be redeemed from the proceeds received by the Preferred Stock
          Depositary resulting from any redemption, in whole or in part, of such
          series of the Preferred Stock held by the Preferred Stock Depositary.
          The redemption price per Depositary Share will be equal to the
          applicable fraction of the redemption price per share payable with
          respect to such series of the Offered Preferred Stock.  If the Company
          redeems shares of a series of Offered Preferred Stock held by the
          Preferred Stock Depositary, the Preferred Stock Depositary will redeem
          as of the same redemption date the number of Depositary Shares
          representing the shares of Preferred Stock so redeemed.  If less than
          all the Depositary Shares are to be redeemed, the Depositary Shares to
          be redeemed will be selected by lot or substantially equivalent method
          determined by the Preferred Stock Depositary.

               After the date fixed for redemption, the Depositary Shares so
          called for redemption will no longer be deemed to be outstanding and
          all rights of the holders of the Depositary Shares will cease, except
          the right to receive the moneys payable upon such redemption and any
          money or other property to which the holders of such Depositary Shares
          where entitled upon such redemption, upon surrender to the Preferred
          Stock Depositary of the Depositary Receipts evidencing such Depositary
          Shares.  Any funds deposited by the Company with the Preferred Stock
          Depositary for any Depositary Shares that the holders thereof fail to
          redeem will be returned to the Company after a period of two years
          from the date such funds are so deposited.

               Voting the Preferred Stock

               Upon receipt of notice of any meeting at which the holders of any
          series of the Offered Preferred Stock are entitled to vote, the
          Preferred Stock Depositary will mail the information contained in such
          notice of meeting to the record holders of the Depositary Shares
          relating to such series of Offered Preferred Stock. Each record holder
          of such Depositary Shares on the record date (which will be the same
          date as the record date for the related series of Offered Preferred
          Stock) will be entitled to instruct the Preferred Stock Depositary as
          to the exercise of the voting rights pertaining to the number of
          shares of the series of Offered Preferred Stock represented by such
          holder's Depositary Shares. The Preferred Stock Depositary will
          endeavor, insofar as practicable, to vote or cause to be voted the
          number of shares of the Preferred Stock represented by such Depositary
          Shares in accordance with such instructions, provided the Offered
          Preferred Stock Depositary receives such instructions sufficiently in
          advance of such meeting to enable it to so vote or cause to be voted
          the shares of Offered Preferred Stock, and the Company will agree to
          take

                                       22
<PAGE>
 
          all reasonable action that may be deemed necessary by the Preferred
          Stock Depositary in order to enable the Preferred Stock Depositary to
          do so. The Preferred Stock Depositary will abstain from voting shares
          of the Offered Preferred Stock to the extent it does not receive
          specific instructions from the holders of Depositary Shares
          representing such Offered Preferred Stock.

               Withdrawal of Preferred Stock

               Upon surrender of the Depositary Receipts at the corporate trust
          office of the Preferred Stock Depositary and upon payment of the
          taxes, charges and fees provided for in the Deposit Agreement and
          subject to the terms thereof, the holder of the Depositary Shares
          evidenced thereby will be entitled to delivery at such office, to or
          upon his or her order, of the number of whole shares of the related
          series of Offered Preferred Stock and any money or other property, if
          any, represented by such Depositary Shares. Holders of Depositary
          Shares will be entitled to receive whole shares of the related series
          of Offered Preferred Stock, but holders of such whole shares of
          Offered Preferred Stock will not thereafter be entitled to deposit
          such shares of Offered Preferred Stock with the Preferred Stock
          Depositary or to receive Depositary Shares thereof. If the Depositary
          Receipts delivered by the holder evidence a number of Depositary
          Shares in excess of the number of Depositary Shares representing the
          number of whole shares of the related series of Offered Preferred
          Stock to be withdrawn, the Preferred Stock Depositary will deliver to
          such holder or upon his or her order at the same time a new Depositary
          Receipt evidencing such excess number of Depositary Shares.

               Amendment and Termination of the Deposit Agreement

               The form of Depositary Receipt evidencing the Depositary Shares
          and any provisions of the Deposit Agreement may at any time and from
          time to time be amended by agreement between the Company and the
          Preferred Stock Depositary. However, any amendment that materially
          adversely alters the rights of the holders of Depositary Shares will
          not be effective unless such amendment has been approved by the
          holders of at least a majority of the Depositary Shares then
          outstanding. Every holder of a Depositary Receipt at the time such
          amendment becomes effective will be deemed, by continuing to hold such
          Depositary Receipt, to be bound by the Deposit Agreement as so
          amended. Notwithstanding the foregoing, in no event may any amendment
          impair the right of any holder of any Depositary Shares, upon
          surrender of the Depositary Receipts evidencing such Depositary Shares
          and subject to any conditions specified in the Deposit Agreement, to
          receive shares of the related series of Offered Preferred Stock and
          any money or other property represented thereby, except in order to
          comply with mandatory provisions of applicable law. The Deposit
          Agreement may be terminated by the Company at any time upon not less
          than 60 days prior written notice to the Preferred Stock Depositary,
          in which case, on a date that is not later than 30 days after the date
          of such notice, the Preferred Stock Depositary shall deliver or make
          available for delivery to holders of Depositary Shares, upon surrender
          of the Depositary Receipts evidencing such Depositary Shares, such
          number of whole or fractional shares of the related series of Offered
          Preferred Stock as are represented by such Depositary Shares. The
          Deposit Agreement shall automatically terminate after all outstanding
          Depositary Shares have been redeemed or there has been a final
          distribution in respect of the related series of Offered Preferred
          Stock in connection with any liquidation, dissolution or winding up of
          the Company and such distribution has been distributed to the holders
          of Depositary Shares.

                The Company will pay all transfer and other taxes and the
          governmental charges arising solely from the existence of the
          depositary arrangements. The Company will pay the charges of the
          Preferred Stock Depositary, including charges in connection with the
          initial deposit of the related series of Offered Preferred Stock and
          the initial issuance of the Depositary Shares and all withdrawals of
          shares of the related series of Offered Preferred Stock, except that
          holders of Depositary Shares will pay other transfer and other taxes
          and governmental charges and such other charges as are expressly
          provided in the Deposit Agreement to be for their accounts.

               Resignation and Removal of Depositary

               The Preferred Stock Depositary may resign at any time by
          delivering to the Company written notice of its election to do so, and
          the Company may at any time remove the Depositary, any such
          resignation or removal to take effect upon the appointment of a
          successor Preferred Stock Depositary, which successor Preferred Stock
          Depositary must be appointed within 60 days after delivery of the
          notice of resignation or removal and must be a bank or trust company
          having its principal office in the United States and having a combined
          capital and surplus of at least $50,000,000.

               Miscellaneous

               The Preferred Stock Depositary will forward to the holders of
          Depositary Shares all reports and communications from the Company that
          are delivered to the Preferred Stock Depositary and which the Company
          is required to furnish to the holders of the Offered Preferred Stock.

               Neither the Preferred Stock Depositary nor the Company will be
          liable if it is prevented or delayed by law or any circumstance beyond
          its control in performing its obligations under the Deposit Agreement.
          The obligations of the Company and the Preferred Stock Depositary
          under the Deposit Agreement will be limited to performance with best
          judgment and in the good faith of their duties thereunder, except that
          they are liable for gross negligence and willful misconduct in the
          performance of their duties thereunder, and they will not be obligated
          to appear in, prosecute or defend any legal proceeding in respect of
          any Depositary Receipts, Depositary Shares or series of Preferred
          Stock unless satisfactory indemnity is furnished.  The Preferred Stock
          Depositary and the Company may rely on advice of legal counsel or
          accountants of their choice, or information provided by persons
          presenting Preferred Stock for deposit, holders of Depositary Shares
          or other persons believed in good faith to be competent and on
          documents believed to be genuine.

               The Preferred Stock Depositary's corporate trust office will be
          identified in the applicable Prospectus Supplement. Unless otherwise
          set forth in the applicable Prospectus Supplement, the Preferred Stock
          Depositary will act as transfer agent and registrar for Depositary
          Receipts and if shares of a series of Offered Preferred Stock are
          redeemable, the Preferred Stock Depositary will act as redemption
          agent for the corresponding Depositary Receipts.

          Common Stock

               The holders of Common Stock are entitled to one vote for each
          share held of record on all matters submitted to a vote of
          stockholders except as otherwise provided by law. There are no
          cumulative voting rights with respect to the election of directors.
          Holders of Common Stock are entitled to receive ratably

                                       24
<PAGE>
 
          such dividends as may be declared by the Board of Directors out of
          legally available funds. In the event of dissolution of the Company,
          they will be entitled to share ratably in all assets remaining after
          payment of liabilities and amounts owed in respect of outstanding
          Preferred Stock, including any Offered Preferred Stock and the
          Existing Preferred Stock. Holders of Common Stock have no preemptive
          rights and have no right to convert their Common Stock into any other
          securities.

               The transfer agent and registrar for the Common Stock is The
          First National Bank of Boston.



          $2.625 Convertible Preferred Stock

               On February 25, 1994, the Company issued 2,760,000 shares of
          Preferred Stock designated the "$2.625 Cumulative Convertible
          Preferred Stock." Holders of the $2.625 Convertible Preferred Stock
          are entitled to receive dividends quarterly at an annual rate of
          $2.625 per share, when and as declared by the Board of Directors out
          of funds legally available therefor. Such dividends are cumulative.

               The $2.625 Convertible Preferred Stock has a Liquidation
          Preference of $50 per share. Holders of $2.625 Convertible Preferred
          Stock are entitled, in the event of the Company's liquidation, to
          share ratably in all of the Company's assets remaining after payment
          of all its debts and liabilities up to the amount of the Liquidation
          Preference set forth above, plus all accrued and unpaid dividends. The
          rights of holders of $2.625 Convertible Preferred Stock rank upon
          liquidation of the Company on a parity with the $2.28 Preferred Stock
          and prior to the holders of the Common Stock and of any other series
          of Preferred Stock which is not specifically on a parity with or
          senior to the $2.625 Convertible Preferred Stock.

               The $2.625 Convertible Preferred Stock is redeemable on or after
          February 16, 1997 at a price per share ranging from 103.675% of the
          Liquidation Preference on February 16, 1997 to 100% thereof on or
          after February 16, 2004, plus in all instances all accrued and unpaid
          dividends.

               Each share of $2.625 Convertible Preferred Stock is convertible
          into such number of shares of Common Stock as is equal to the
          Liquidation Preference of such share divided by the Conversion Price.
          As of the date hereof, the Conversion Price is $39.750, subject to
          adjustment for stock dividends, stock splits and other dilutive
          events.

               Holders of $2.625 Preferred Stock have no voting rights except as
          set forth below or as otherwise from time to time required by law.
          Whenever dividends on the $2.625 Preferred Stock or any other class or
          series of stock ranking on a parity with the $2.625 Preferred Stock
          with respect to the payment of dividends shall be in arrears for
          dividend periods, whether or not consecutive, containing in the
          aggregate a number of days equivalent to six calendar quarters, the
          holders of shares of $2.625 Preferred Stock (voting separately as a
          class with all other series of Preferred Stock upon which like voting
          rights have been conferred and are exercisable) will be entitled to
          vote for the election of two of the authorized number of directors of
          the Company at the next annual meeting of stockholders and at each
          subsequent meeting until all dividends accumulated on the $2.625
          Preferred Stock and all other series of Preferred Stock ranking on a
          parity as to dividends with the $2.625 Preferred Stock shall have been
          fully paid or set apart for payment. The term of office of all
          directors elected by the holders of such Preferred Stock shall

                                       25
<PAGE>
 
          terminate immediately upon the termination of the right of the holders
          of such Preferred Stock to vote for directors. Holders of shares of
          $2.625 Preferred Stock have one vote for each share held.

               So long as any shares of the $2.625 Preferred Stock remain
          outstanding, the Company shall not, without the consent of holders of
          at least two-thirds of the shares of $2.625 Preferred Stock
          outstanding at the time, voting separately as a class with all other
          series of Preferred Stock upon which like voting rights have been
          conferred and are exercisable, (i) issue or increase the authorized
          amount of any class or series of stock ranking prior to the
          outstanding $2.625 Preferred Stock as to dividends or upon liquidation
          or (ii) amend, alter or repeal the provisions of the Company's
          Certificate of Incorporation or of the resolutions contained in the
          Certificate of Designation relating to the $2.625 Preferred Stock,
          whether by merger, consolidation or otherwise, so as to materially
          adversely affect any power, preference or special right of the
          outstanding $2.625 Preferred Stock or the holders thereof; provided,
          however, that any increase in the amount of the authorized Common
          Stock or authorized Preferred Stock or any increase or decrease in the
          number of shares of any series of Preferred Stock or the creation and
          issuance of other series of Common Stock or Preferred Stock ranking on
          a parity with or junior to the $2.625 Preferred Stock as to dividends
          and upon liquidation, dissolution or winding up shall not be deemed to
          materially adversely affect such powers, preferences or special
          rights.

 
          $2.28 Preferred Stock

               On November 19, 1992, the Company authorized and issued 1,400,000
          shares of Preferred Stock designated "$2.28 Cumulative Preferred
          Stock." Holders of $2.28 Preferred Stock are entitled to receive
          dividends quarterly at an annual rate of $2.28125 per share, when and
          as declared by the Board of Directors out of funds legally available
          therefor. Such dividends are cumulative.

               The $2.28 Preferred Stock has a liquidation preference of $25.00
          per share. Holders of $2.28 Preferred Stock are entitled, in the event
          of the Company's liquidation, to share ratably in all of the Company's
          assets remaining after payment of all of its debts and liabilities up
          to the amount of the liquidation preference set forth above, plus all
          accrued and unpaid dividends. The rights of holders of $2.28 Preferred
          Stock rank upon liquidation of the Company on a parity with the $2.625
          Preferred Stock and prior to those of the holders of the Common Stock
          and of any other series of Preferred Stock which is not specifically
          on a parity with or senior to the $2.28 Preferred Stock.

               The $2.28 Preferred Stock is redeemable on or after November 15,
          1997 at a redemption price equal to $25.00 per share plus in all
          instances all accrued and unpaid dividends.

               Holders of $2.28 Preferred Stock have no voting rights except as
          set forth below or as otherwise from time to time required by law.
          Whenever dividends on the $2.28 Preferred Stock or any other class or
          series of stock ranking on a parity with the $2.28 Preferred Stock
          with respect to the payment of dividends shall be in arrears for
          dividend periods, whether or not consecutive, containing in the
          aggregate a number of days equivalent to six calendar quarters, the
          holders of shares of $2.28 Preferred Stock (voting separately as a
          class with all other series of Preferred Stock upon which like voting
          rights have been conferred and are exercisable) will be entitled to
          vote for the election of two of the authorized number of directors of
          the Company at the next annual meeting of stockholders and at each
          subsequent meeting until all dividends accumulated on the $2.28
          Preferred Stock and all other series of Preferred Stock ranking on a
          parity as to dividends with the $2.625 Preferred Stock shall have been
          fully paid or set apart for payment. The term of office of all
          directors elected by the holders of such Preferred Stock shall
          terminate

                                       26
<PAGE>
 
          immediately upon the termination of the right of the holders of such
          Preferred Stock to vote for directors. Holders of shares of $2.28
          Preferred Stock have one vote for each share held.

               So long as any shares of the $2.28 Preferred Stock remain
          outstanding, the Company shall not, without the consent of holders of
          at least two-thirds of the shares of $2.28 Preferred Stock outstanding
          at the time, voting separately as a class with all other series of
          Preferred Stock upon which like voting rights have been conferred and
          are exercisable, (i) issue or increase the authorized amount of any
          class or series of stock ranking prior to the outstanding $2.28
          Preferred Stock as to dividends or upon liquidation or (ii) amend,
          alter or repeal the provisions of the Company's Certificate of
          Incorporation or of the resolutions contained in the Certificate of
          Designation relating to the $2.28 Preferred Stock, whether by merger,
          consolidation or otherwise, so as to materially adversely affect any
          power, preference or special right of the outstanding $2.28 Preferred
          Stock or the holders thereof; provided, however, that any increase in
          the amount of the authorized Common Stock or authorized Preferred
          Stock or any increase or decrease in the number of shares of any
          series of Preferred Stock or the creation and issuance of other series
          of Common Stock or Preferred Stock ranking on a parity with or junior
          to the $2.28 Preferred Stock as to dividends and upon liquidation,
          dissolution or winding up shall not be deemed to materially adversely
          affect such powers, preferences or special rights.

          Registration Rights

                The Company has a registration rights agreement with certain
          principal stockholders, including the Selling Stockholder, granting
          them the right to require the Company to effect one registration of
          any or all of their Common Stock at their expense. In addition, they
          have the right to have any or all of such Common Stock included, at
          their pro rata expense, in any registration statement relating to the
          Common Stock filed by the Company, subject to the right of the
          underwriter of that offering to limit the number of shares of such
          Common Stock to be included in that registration.

          Certain Provisions of Certificate of Incorporation and Delaware Law

               The Company's Certificate of Incorporation contains certain
          provisions that may have an effect of delaying, deferring or
          preventing a change of control of the Company. First, the Certificate
          of Incorporation provides that the Board shall consist of three
          classes of Directors, each serving a three-year term ending in a
          successive year. This provision may make it more difficult to effect a
          takeover of the Company because it would generally take two annual
          meetings of stockholders for an acquiring party to elect a majority of
          the Board. As a result, the classified Board may discourage proxy
          contests for the election of Directors or purchases of a substantial
          block of stock because it could operate to prevent obtaining control
          of the Board in a relatively short period of time.

               In addition, the Certificate of Incorporation provides that the
          holders of a minimum of 60% of the Company's capital stock entitled to
          vote on a manner (or such higher percentage as may otherwise be
          required) may take action thereon without a meeting by executing a
          written consent or consents. This increases the percentage that would
          otherwise be required under Delaware law to take certain actions by
          written consent, and thus may make it more difficult to effect a
          takeover of the Company involving certain transactions, such as a
          merger or sale of assets, by requiring a potential acquiror to obtain
          a higher percentage of the Company's voting securities or hold a
          stockholders' meeting before such a transaction could be consummated.

                                       27
<PAGE>
 
       The Company is subject to Section 203 of the Delaware General Corporation
Law, which provides for restrictions on business combinations (as defined
therein) with interested persons (any person who acquires 15% or more of the
Company's outstanding voting stock). In general, the Company is prohibited from
engaging in business combinations with an interested person for a period of
three years from the date a person becomes an interested person, subject to
certain exceptions. By restricting the ability of the Company to engage in
business combinations with an interested person, the application of Section 203
to the Company may provide a barrier to hostile or unwanted takeovers.

rather than pursuant to this Prospectus.

       Offers to purchase Securities may be solicited directly by the Company or
the Selling Stockholder or by agents designated by the Company or the Selling
Stockholder from time to time. Any such agent, who may be deemed to be an
underwriter as that term is defined in the Securities Act of 1933, involved in
the offer or sale of the Securities in respect of which this Prospectus is
delivered will be named, and any commissions payable by the Company or the
Selling Stockholder to such agent will be set forth, in the accompanying

of its appointment (ordinarily five business days or less).

<PAGE>
 
       If an underwriter or underwriters are utilized in the sale, the Company
and, if applicable, the Selling Stockholder, will execute an underwriting
agreement with such underwriters at the time of sale to them and the names of
the underwriters and the terms of the transaction will be set forth in the
accompa nying Prospectus Supplement, which will be used by the underwriters to
make resales of the Securities in respect of which this Prospectus is delivered
to the public.

       If a dealer is utilized in the sale of the Securities in respect of which
this Prospectus is delivered, the Company or the Selling Stockholder will sell
such Securities to the dealer, as principal. The dealer may then resell such
Securities to the public at varying prices to be determined by such dealer at
the time of resale. The name of the dealer and the terms of the transaction will
be set forth in the accompanying Prospectus Supplement.

       Agents, underwriters and dealers may be entitled under the relevant
agreements to indemnification by the Company or the Selling Stockholder against
certain liabilities, including liabilities under the Securities Act. Agents,
dealers and underwriters may be customers of, engage in transactions with, or
perform services for the Company in the ordinary course of business.

       The place and time of delivery for the Securities in respect of which
this Prospectus is delivered are set forth in the accompanying Prospectus
Supplement.

Item 15.  Indemnification of Directors and Officers

       The Company's Bylaws incorporate substantially the provisions of the
General Corporation Law of the State of Delaware providing for indemnification
of directors, officers, employees and agents of the Company against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with any proceeding arising by reason of the fact that such person
is or was an officer, director, employee or agent of the Company. In addition,
the Company is authorized to enter into indemnification agreements with its
directors and officers providing mandatory indemnification to them to the
maximum extent permissible under Delaware law.

       As permitted under Delaware law, the Company's Certificate of
Incorporation provides for the elimination of the personal liability of a
director to the corporation and its stockholders for monetary damages arising
from a breach of the director's fiduciary duty of care. The provision is limited
to monetary damages, applies only to a director's actions while acting within
such person's capacity as a director, and does not entitle the Company to limit
director liability for any judgment resulting from (a) any breach of the
director's duty of loyalty to the Company or its stockholders; (b) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of the law; (c) paying an illegal dividend or approving an illegal
stock repurchase; or (d) any transaction from which the director derived an
improper benefit. In addition, Section 145 of the General Corporation Law of the
State of Delaware provides generally that a person sued as a director, officer,
employee or agent of a corporation may be indemnified by the corporation for
reasonable expenses, including counsel fees, if in the case of other than
derivative suits, such person has acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
corporation (and in the case of a criminal proceeding, and no reasonable cause
to believe that such person's conduct was unlawful). In the case of a derivative
suit, an officer, employee or agent of the corporation who is not protected by
such provisions

                                     II-1
<PAGE>
 
in the Certificate of Incorporation, may be indemnified by the corporation for
reasonable expenses, including attorneys' fees, if such person has acted in good
faith and in a manner such person reasonably believed to be in or not opposed to
the best interests of the corporation, except that no indemnification shall be
made in the case of a derivative suit in respect of any claim as to which an
officer, employee or agent has been adjudged to be liable to the corporation
unless the Delaware Court of Chancery or the court in which such action or suit
was brought shall determine that such person is fairly and reasonably entitled
to indemnity for proper expenses. Indemnification is mandatory in the case of a
director, officer, employee or agent who is successful on the merits in defense
of a suit against such person.

Item 17.  Undertakings

          The undersigned Registrant hereby undertakes:

       (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

          (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
the effective date of the Registration Statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, represent
a fundamental change in the information set forth in the Registration Statement;

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement;

                                     II-3
<PAGE>
 
       provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the Registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the Registration Statement.

       (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

       (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

       (4)  That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in this Registration Statement shall be deemed to be a new Registration
Statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

        (5)  That, for purposes of determining any liability under the
Securities Act of 1933, the information omitted from the form of prospectus
filed as part of this Registration Statement in reliance upon Rule 430A and
contained in a form of prospectus filed by the Registrant pursuant to Rule
424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part
of this Registration Statement as of the time it was declared effective.

       Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Company pursuant to the foregoing provisions, or otherwise, the Company has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Company of expenses incurred or
paid by a director, officer or controlling person of the Company in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                     Shares of Common Stock, par value
                                     $.10 per share, of Selling Stockholder

Dear Sirs,

        I am Vice President-General Counsel for Western Gas Resources, Inc., a 
Delaware corporation (the "Corporation"). I have participated in the preparation
of a registration statement on Form S-3 (the "Registration Statement") with 
respect to the sale by Brian Wise of 150,000 shares (the "Stockholder Shares") 
of common stock, par value $.10 per share, of the Corporation.

        I have examined the originals, or copies certified or otherwise 
authenticated to my satisfaction, of such corporate records of the Corporation, 
certificates of public officials and of officers of the Corporation, and other 
agreements, instruments and documents as I have deemed necessary as a basis for 
the opinions herein expressed.

        On the basis of the foregoing and the assumptions hereinafter set forth,
and in reliance thereon, I advise you that, in my opinion:

        1.      The Corporation has been duly incorporated and is validly
                existing and in good standing under the laws of the State of
                Delaware.

        2.      The Stockholder Shares have been duly authorized by the
                Corporation and are legally issued, fully paid and non-
                assessable.

        I am a member of the Bar of the State of Colorado only and do not 
purport to be an expert on the laws of any other state or jurisdiction other 
than the State of Colorado and the United States. Insofar as opinions herein 
expressed relate to matters governed by Delaware law, I have relied solely upon 
a reading of the applicable statutes and the records of the Corporation and 
certificates of public officials referenced above with respect to the opinions 
given herein.

                                        Respectfully submitted,


                                        John C. Walter, Esq.

                                                                     Exhibit 5.2

    For the purpose of computing the ratio of earnings to fixed charges, earnings consist of income 
before income taxes and fixed charges.  Fixed charges consist of (i) interest (including capitalized
interest, but excluding amortization of amounts previously capitalized) on all indebtedness; (ii) 
amortization of debt discount and expense; and (iii) that portion (one-third) of rental expense
which the Company believes to be representative of interest.

       For the purpose of computing the ratio of earnings to combined fixed charges and preferred stock 
dividends, earnings consist of income before income taxes and fixed charges and preferred stock
dividends.  Fixed charges consist of (i) interest (including capitalized interest, but excluding 
amortization of amounts previously capitalized) on all indebtedness; (ii) amortization of debt discount
and expense;  (iii) that portion (one-third) of rental expense which the Company believes to be 
representative of interest; and (iv) preferred dividends as adjusted for taxes. The ratio for the year
ended December 31, 1991 includes approximately $3 million related to the prepayment in the second quarter 
of the remaining preference distributions of $1.75 per unit to minority holders in the predecessor
company.  Preferred dividends for the years ended December 31, 1991 through December 31, 1994 include 
quarterly dividends on the 7.25% Cumulative Senior Perpetual Convertible Preferred Stock.  In May of
1995, the Company redeemed the 7.25% Cumulative Senior Perpetual Convertible Preferred Stock; thus, the 
ratio for the year ended December 31, 1995 includes dividends paid of $1.2 million, a redemption premium 
of $2.0 million and up-front costs of $1.8 million related to this redemption.  The ratio also includes 
quarterly dividends on the $2.28 Cumulative Convertible Preferred Stock since November 1992 and quarterly 
dividends on the $2.625 Cumulative Convertible Preferred Stock since February 1994.
